Revenge in Shakespeares The Tempest Essay -- The Tempest Essays

Revenge in Shakespeare's The Tempest The nucleus of the plot in Shakespeare's The Tempest revolves around Prospero enacting his revenge on various characters who have wronged him in different ways. Interestingly enough, he uses the spirit of Ariel to deliver the punishments while Prospero delegates the action. Prospero is such a character that can concoct methods of revenge but hesitates to have direct involvement with disillusioning his foes. In essence, Prospero sends Ariel to do his dirty work while hiding his involvement in shipwrecking his brother, Antonio, from his daughter, Miranda. Prospero, the "rightful" duke of Milan, primarily seeks revenge against two people, Antonio and Caliban. But, Prospero allows his anger toward them to trickle to the other castaways on the island. He encourages Ariel to separate Sebastian, Duke Alonso's brother, from his son Ferdinand during the raging sea storm, causing Sebastian to assume his son has drowned. (1.2.213-224) The other "drunkards" on the island also feel the brunt of Prospero's revenge against Caliban when Ariel tempts them with a banquet stocked with alcohol and then disillusions them into thinking the banquet was a figment of their imagination. (2.1) But why the tendency toward revenge in the first place? What was it about the personality and mental disposition of Prospero that caused him to lust for revenge against his brother, Antonio? And Caliban. Why couldn't Prospero overlook his social naà ¯vetà © when it came to handling a woman?

Exploring the Relationship Between Mother and Baby Essay

Exploring the relationship between mother and baby in the NICU in relation to nursing support. Abstract Aim -To explore the effect of interaction related to care-giving and information exchange between nurses and mothers in relation to maternal stress and maternal-infant relationship in the newborn intensive care unit (NICU) throughout the hospital stay. Background – Mothers in the NICU experience depression, anxiety, stress, and loss of control, and they fluctuate between feelings of inclusion and exclusion related to the provision of health care to their neonate. This literature review helps to identify nursing interventions that promote positive outcomes between mother and baby by reducing maternal feelings of stress and anxiety. Search Method – A literature search covering the period 2008-2012 was conducted. Five articles reporting both quantitative and qualitative studies relative to the subject were retrieved. Findings – Findings reveal that positive and trustful relationships between nurses and mothers develop when nurses communicate and interact with mothers. This alleviated mother’s anxiety and enhanced their confidence when interacting with their baby. Discussion – Critical analysis as well as strengths and weaknesses of the relative journals reviewed is given together with useful recommendations that emerge from the evidence. Conclusion – The literature reviewed shows that nurse-mother interaction improves mother-infant relationship. In turn, this will eventually assist in decreasing maternal stress and improve the maternal well-being. INTRODUCTION Mothers develop attachment to their baby during pregnancy, which continues and develops more fully after the child is born (Cleveland 2009). However, the pathway to becoming a mother is threatened with the admission of the baby to the NICU. This occurs due to the unfamiliar and intimidating environment of the NICU (Obeidat et al 2009). During the initial admission parents can believe that the healthcare team is more able to care for their baby and this can instill feelings of inadequacy (Cockfort 2011). As a result, maternal attachment may be delayed by the lack of socialisation between mother and baby as most of the care is done by nurses (Cleveland 2009). DeRouck and Leys (2009), found that the parents of an infant admitted to the NICU face challenges including access to information, disclosure about the diagnosis, treatment and prognosis of their newborn, as well as a lack of control over the care of their newborn. Adding to this distress is the uncertainty of survival or the eventual impact of the infant’s condition on later health and well-being. In addition, feeling guilty to mother an unhealthy infant creates fear of social prejudice. Further, the structure of the NICU places significant barriers on mothers’ abilities to enact the parental role since decision-making and the daily care of the infant is taken over by medical and nursing staff restricting interactions with the babies stripping off their maternal authority (Cleveland 2009). In fact, when babies are in the NICU, traditional conceptualizations of the parental role are altered. The situation demands heightened parental participation while simultaneously placing severe restrictions on parental involvement. In response, parents need to negotiate this tension and traditional definitions of the parental role, which must be continually redefined throughout their experience What emerges is that the predominant source of distress is inability of the mother to protect the infant from pain and provide appropriate pain management. (Fenwick et al 2008). A lot of procedures cause pain in the neonate creating concerns for the mother, starting from peripheral cannulas, indwelling catheters and intubation to mention a few. In intubated babies, even though morphine infusions are administered, the baby still shows signs of distress during nursing times. In this case, we administer a small bolus of pain relief prior to nursing so that the baby would be more comfortable. Conversely, Fenwick et al (2008) describes factors that contribute to parents’ satisfaction in the NICU. These include; assurance and psychological support, the provision of consistent information, education, environmental follow-up care, appropriate pain management, and parental participation and proximity, as well as physical and spiritual support. Therefore, it is imperative that nurses should do their best to improve the mothers’ sense of confidence, competence and connection with her infant through guided participation (Domanico et al 2011). Johnson (2008) notes that skin-to-skin holding or kangaroo care promotes maternal-infant feelings of closeness, builds maternal confidence, and may be a stress-reducing experience for both the mother and infant. Hence the importance of providing the opportunity for kangaroo care to occur. Hunt (2008), notes that KMC is also crucial to stabilize parameters, such as cardio-respiratory parameters whilst being beneficial for maintaining body temperature. They add that even the incidence of nosocomial sepsis and the duration of hospital stay decreased with practicing KMC. In addition, Ali et al., (2009), found that Kangaroo mother care also showed positive outcomes towards practicing exclusive breastfeeding. Cockfort (2011) notes that, continuity of care needs to be ensured hence the importance of documentation. Therefore, it is suggested that handover should not be rushed, whilst a more comprehensive handover can ensure the smooth transition of care for staff and the family. When parents ask questions relating to their baby they feel assured in the competency of staff when information has been passed on correctly. When information is not shared effectively parents can lose trust and the partnership breaks down. In Malta, even though handover of 2 consecutive days is given, conflicting advice is still given at times due to the nurses’ different view-points. Consequently, this requires ward meetings in order to clarify important issues so that advice given and practice is consistent. In Malta, about 373 babies are admitted yearly (Grech et al 2012). In view of the benefits discussed, nurses should do their utmost to improve the overall experience of the mothers of such babies. Search Method A review of published research consisted of the following steps; broad reading to determine areas of focus, identification of inclusion and exclusion criteria, literature search (appendix 1) and retrieval, critical appraisal and analysis of the research evidence and synthesis of evidence. Evidence was reviewed with the aims of identifying barriers that affect the motherinfant interaction within the neonatal intensive care unit and how nurses can actively support attachment. Articles were included if the setting was primarily in a neonatal intensive care unit (neonatal unit or neonatal intensive care unit) and the participants were mothers of infants admitted to neonatal intensive care units or nurses working within that setting. In addition, All articles were critically analyzed with two primary questions in mind: (a) What are the needs of parents in the NICU? (b) What nursing behaviors support parents in meeting these needs? Articles were also included if they were primary research studies published between 2008 and 2012 and written in the English language. Primary and secondary literature searches were conducted through the EBSCO, ERIC, Sciencedirect and Medline databases. The primary search terms included â€Å"NICU,† â€Å"Neonatal Intensive Care Unit,† â€Å"family support,† â€Å"communication,† â€Å"nurse† and â€Å"early intervention.† The secondary literature search terms included â€Å"nursing support,† â€Å"efficacy,† â€Å"family,† â€Å"communication,† â€Å"support†, â€Å"neonatal† and â€Å"Kangaroo Mother Care†. These terms were used and utilised in all possible combinations to perform an extensive literature search of the above mentioned electronic databases. Thirdly, a review of references was conducted of the identified articles for any further studies. Eighteen articles were found through the search. Six studies met the inclusion criteria of which, 3 were qualitative and 3 quantitative (appendix 2). The subject was limited to the last 5 years. This time frame helps in the getting the most recent experiences since NICU is a changing environment especially as regards to technology which effects the mothers as well as the nurses. Both quantitative and qualitative studies were found. Both qualitative and quantitative research was conducted to identify what is known about the needs of NICU parents and what behaviours support these parents. Both methods of research were included because of the potential for each to contribute to a more complete understanding of this topic. In selecting a research design, researchers should be guided by one overarching consideration: whether the design does the best possible job of providing trustworthy answers to the research questions. One needs to note that both studies have limitations (Cottrell & McKenzie, 2011). In quantitative research, the researcher’s aim is to determine the relationship between one variable (an independent variable) and another (a dependent or outcome variable) in a population (Morrow 2009). In contrast to quantitative designs, qualitative designs do not result in numerical data for statistical analysis (Schira, 2009). In qualitative methods, researchers are interested in interpreting social phenomena and exploring the meanings that people attach to their experiences (Polit and Beck 2010). Moreover, views, attitudes and behaviours may be explored (Wood & Kerr, 2011), through grounded theory as it develops theories that are â€Å"grounded† in the group’s observable experiences, but researchers add their own insight into why those experiences exist. Findings Table 1 includes information about the 5 studies that met the inclusion criteria . Once an infant is admitted into an NICU, many factors account for parental stress. Admission of the infant to the NICU places mothers in a stressful situation where they must cope with the NICU environment and its associated demands. In the study conducted by Parker (2011), a grounded theory approach was used to understand feeling and stressors of 11 mothers whose new-borns were in the NICU. It was found that the early days shock and numbness accompanied feelings of none or little control over their lives. Moreover, all mothers described feeling unprepared for the premature delivery and the sight of their baby in the NICU. Comparative results were found by Lee et al (2009), with regards to the shock experienced with the initial sight of the baby. Everyday unpredictable changes occur leaving no time for adjustment or preparation. Constant fears about the life and death of the baby do not subside and several mothers spoke about their experience of always anticipating the death of the baby. These findings are also reflected in my clinical setting when mothers would be recounting their experience once the baby’s condition improves. This is in line with the findings of Fenwick et al (2009) and Lee et al (2009). In addition, the findings imply that the positive reassurance of the effects of a positive and caring environment and support network between parents and nurses in the NICU is not always evident among every unit. Nicholas-Sargent (2009) found that assurance is the most important aspect to be fulfilled. Her quantitative study of 46 mothers found that the length of stay in the NICU and mothers’ information needs were found to be significantly inversely correlated. Therefore, this suggests that the longer an infant remains hospitalized in the NICU, the less emphasis the mother places on receiving information about the infant’s condition. This shows that the needs of the mothers in the NICU can change over time. My observations match these findings since mothers familiarise themselves and adapt to the situation. Moreover, they would eventually want to be successful with the care of the baby. This is reflected in the grounded theory analysis conducted by Fenwick et al (2008), using semi-structured interviews. They found that the nurse-mother relationship had the potential to significantly affect how women perceived their connection to the infant and their confidence in caring for their infant which occurred through a three way interaction. Being successful in their desire to care for the baby, engendered feelings associated with being a ‘‘real’’ mother. However, not all women in this study were able to successfully employ these strategies. In the situation where the mother perceived herself as ‘‘quiet and unassertive’’, and in a position without any power, it was very difficult to gain the confidence needed in order to be able to openly question, negotiate and direct the care of her infant. Therefore, it is very important to identify these mothers in order to help them by giving them continuous reassurance. This would particularly be required when the situation changes from support needing to encouragement in participation. Lee et al (2009) found that mothers received support from the healthcare professionals and the social networks that mothers made. These helped to create the connections that developed between the mothers and infants making their journey towards parenthood possible. They discovered that challenges are further compounded in Taiwan, where women are traditionally required to practice the cultural ritual which includes confinement to the house with a special balanced diet for the first month postnatal. Lee et al (2009) used the grounded theory approach with in-depth interviews and constant comparison. All interviews were audio-taped and notes were made during and immediately after the interview concerning actions and body language of the mother during the interview. The finding of this study further indicated that the initial sight of the life-support equipment was shocking. The technological environment created a fearful atmosphere, and the medical equipment attached to their infants caused the mothers further physical separation. The mothers indicated that they were so afraid of the equipment that it took them a long time to be able to participate in their infants’ care. In turn, this hampered them from establishing positive mother–infant interactions. Chiu and Anderson (2008), found that preterm births often negatively influence mother–infant interaction due to lack of physical contact. In addition, they found that skin-to skin contact post-birth has positive effects on infant development. These researchers conducted a randomized controlled trial (RCT) using questionnaires for data collection. In addition, mothers were further video-taped during a feeding session. Ali et al., (2009),highlight the importance of kangaroo care in their RCT where the researchers conducted their study with one hundred and fourteen infants. This study showed that the infants exposed to kangaroo mother care had an increase in rectal temperature compared to conventional care, therefore having a decreased risk of hypothermia. The mean temperature during kangaroo mother care was of 37 degrees Celsius while the mean temperature during conventional care was of 36.7 degrees Celsius. The data collected was through posted questionnaires. Discussion In the 3 qualitative studies found, the data was collected through interviews of which 2 were semi-structured while 1 was unstructured. Parker (2011), Fenwick et al (2008) and Lee et al (2008), used the Grounded theory approach. However, while Parker and Fenwick use semi-structured interviews, Lee uses unstructured interviews. In semi-structured interviews there is a topic guide with list of areas or questions to be covered with each respondent. This technique ensures that researchers will obtain all the information required, and gives respondents the freedom to respond in their own words, provide as much detail as they wish, and offer illustrations and explanations. Lee et al (2009) uses ground theory approach but incorporated with unstructured interviews. Unstructured interviews also known as are flexible but are more time-consuming than semi-structured since the interviewer listens and does not take the lead. The interviewer listens to what the interviewee has to say. The interviewee leads the conversation (Wood & Ross-Kerr, 2011). However, anonymity for confidentiality which is of utmost importance is not possible. When using unstructured interviews, the researchers have to be able to establish rapport with the participant. The reason is that the interviewers have to be trusted if someone is to reveal intimate life information. This may lead to interviewee bias. Also, it is important to realise that unstructured interviewing can produce a great deal of data which can be difficult to analyse. Lee et al (2008) and Fenwick et al (2008) conducted the interviews themselves while Parker (2011) did not, thus reducing the bias. However, interviewer bias occurs even if someone else is conducting the interview. The number of mothers in the study of Lee et al (2008) was adequate since with in-depth interviews 20 participants are enough. However, to account for the small sample, more interviews and observations were done with the same participants in order to reach theoretical saturation. Usually informants are selected for in-depth interviews in a purposive manner questioning the generalizability of the results (Wood & Kerr, 2011). A major controversy among grounded theory researchers relates to whether to follow the original Glaser and Strauss procedures or to use the adapted procedures of Strauss and Corbin (Polit & Beck 2010). Grounded theory method according to Glaser emphasizes induction or emergence, and the individual researcher’s creativity within a clear frame of stages, while Strauss is more interested in validation criteria and a systematic approach. Parker (2011) uses the original Glaser and Strauss (1967) paradigm while Lee et al (2008) and Fenwick et al (2008) use Strauss and Corbin (1998) procedures. One of the fundamental features of the grounded theory approach is that data collection, data analysis, and sampling of study participants occur simultaneously. A procedure referred to as constant comparison is used to develop and refine theoretically relevant categories. Categories elicited from the data are constantly compared with data obtained earlier in the data collection process so that commonalities and variations can be determined. As data collection proceeds, the inquiry becomes increasingly focused on emerging theoretical concerns. All 3 studies use constant comparison. All the above 3 studies use audio-taping for data collection except for Fenwick et al (2008) who used field note documentation as well. Audio-taping enables eye contact to be maintained and to have a complete record for analyses, however, some interviewees may be nervous of tape-recorders. On the contrary, in note taking on the other hand, a lot of eye contact is lost unless a type of short-hand is learnt. However, the interviewer will have plenty of useful quotations for report when transcribing the interview. Randomized controlled trials consist of a complete experimental test of a new intervention, involving the random assignment of a large and varied sample to different groups (Polit & Beck, 2010). The intention of an RCT is to arrive to a judgment as to whether the novelty of an intervention is more effective than the traditional intervention (Polit & Beck, 2010). This intention was well noticed throughout the RCTs chosen by Ali etal., (2009). Wood & Kerr, (2011) sustain that RCTs are the most rigorous method to determine a cause-effect relationship between the treatment and the outcome. Furthermore, RCTs were also described as the gold standard trial for evaluating the effectiveness of a clinical intervention ((Muijs 2010). One of the primary aims of RCTs is to prevent selection bias by distributing the patient, randomly between the two groups, so that the difference in the outcome and results can be justified and attributed only to the intervention under study. Thus, through random selection there is a better balancing of any confounding factors, therefore creating similarity between the groups (Cottrell & McKenzie, 2010). In effect in this literature review, RCTs were found to be useful and beneficial to compare the effect of KMC and conventional care on the physiological aspects of the infant. Ali et al., (2009) chose to add blocking to randomisation so as to ensure a better balance in the number of infants allocated in the groups. These groups were randomized through simple randomization and the disruption of groups was achieved by delivering a concealed envelope technique. Through random sampling, Polit & Beck (2010) explain that each element in the population has an equivalent, autonomous chance of being chosen. However, this design is not used frequently as it is lengthy and may be expensive (Wood & Kerr, 2011). Chiu and Anderson (2008), use mixed methods of data collection by using both questionnaires and video-taped interviews. The use of multiple sources or referents to draw conclusions about what constitutes the truth is called triangulation. This is one approach in establishing credibility as it enables the researcher to counteract the weaknesses in both designs. The use of video-taping provides the most comprehensive recording of an interview since it captures body language, facial expressions and interaction (Gerrish and Lacey 2010). However the interviewee may become uncomfortable and act differently than in normal circumstances questioning the reliability of the data collected. In addition, questionnaires are the main research tools used in quantitative research. They are very advantageous as they can be constructed in such a way as to meet the objectives of almost any research project. In the Family Needs Inventory used by Nicholas-Sargent (2009), the ‘not applicable’ part was removed from the Likert scale in order to report definite opinions. Questionnaires can measure the participants’ factual knowledge about a certain subject or an idea or else they can be used to explore opinions, attitudes or behaviours (McNabb, 2008). Moreover, questionnaires are also less expensive than most other research instruments and are also less time-consuming . Self-administered questionnaires provide the participants with anonymity, and responses are not affected by the interviewer’s mood or presence (Wood & Ross-Kerr, 2011). On the other hand, the main disadvantage of questionnaires is that there is a high possibility of a poor response rate since some questions are ignored, misinterpreted, incorrectly completed or inadequately detailed (Polit and Beck 2010). The RCT of Chiu and Anderson (2009) and Ali etal. (2009),, is one of the most powerful tools of research where people are allocated at random to receive one of several clinical interventions. However RCT’s are vulnerable to multiple types of bias at all stages of their workspan (Geretsegger et al 2012). Hence the need to establish validity and reliability. In the study done by both Ali etal.,(2009) and Chiu and Anderson (2009),the researchers increase the rigor on the study by using a large number of participants. In addition, Chiu and Anderson (2009) use the Nursing Child Assessment Satellite Training Program (NCAST) Feeding and Teaching scales. Nicholas-Sargent (2009), improved the rigour by using the Critical Care Family Needs Inventory (CCFNI), as a framework for the FNI. CCFNI has been thoroughly reported with results indicating internal consistency and construct validity (Gerrish and Lacey 2010). Despite this, Nicholas-Sargent (2009), use a small scale study and therefor e the results cannot be generalized. Limitations In the study done by Lee et al (2008), the data were only collected from one hospital in this present study causing generalisability of the results to be low. Moreover, the sample was restricted to those who did not have additional social, cultural or medical circumstances to consider. Moreover, coding was done by researcher itself and this might have caused some bias. Both Nicholas-Sargent (2009) and Parker (2011) use small scale studies but these were qualitative studies. Therefore, to a certain extent the findings cannot be generalized across the population of families involved with the NICU. In addition, Parker (2011) uses a retrospective study, which might have been subject to bias in recalling information. There was absence of pilot study in both Nicholas-Sargent (2009) and Chiu and Anderson (2009). The use of pilot studies helps to assess the design, methodology and feasibility of the tool and typically includes participants who are similar to those who will be used in the larger research study ( Wood & Kerr 2011). Hence, their importance. Also, the instruments chosen by Chiu and Anderson (2009), being the (NCAST and the feeding and teaching scales) for this study might not be sensitive enough to capture any between-group difference in changes resulting from the intervention. Finally, Ali et al., (2009) fail to mention intention to treat analysis where researchers can introduce reality into research by outlining that not all randomised participants will continue throughout the study. Therefore, this might be a potential weakness in this study. It was also noted the there was no detailed report about the time intervals between the two different groups. Hence, this may also have introduced performance bias. In the grounded theory approach taken by Fenwich et al (2008), limitations lie in the method of data collection itself through semi-structured interviews that were tape-recorded and field note documentation done. The authors did not acknowledge limitations in the study. Recommendations Maternal contact Fenwich et al (2008) suggests prioritising maternal-infant closeness when underpinning policies and protocols and suggests the unrestricted access to their child. Lee et al (2008) found that in Taiwan mothers are allowed to visit for 30 minutes twice a day. In Malta, mothers are allowed to stay with the child 24 hours a day. In addition, skin-to-skin contact is recommended by both Lee et al (2008) and Chiu and Anderson (2009). The latter suggests that all mothers, if they are able and whether or not they ask for it, skin-to-skin contact should be encouraged. My suggestions on interventions for critically ill infants include encouraging the parents’ presence at the bedside, assisting the parents in personalizing the bedside, and teaching the parents to gently touch their infant. Another approach is to hang a simple picture board with the first names of nurses and practitioners near the entrance to the unit. This picture board helps anxious families feel welcomed in this healing environment. In our unit, those babies who have central lines such as umbilical arterial catheters (UAC), the mothers are not allowed to hold the baby for fear of bleeding if the UAC gets dislodged. However, if the mother shows signs of needing contact with the baby, we allow her to hold the baby with constant supervision. In the case of babies that are ventilated mothers are only allowed to hold their baby if the prognosis is very poor. Therefore, this shows that, if the baby is on long term ventilation, skin-to-skin is hindered from being introduced. Fenwich et al (2008), recommend the development of tools that can better evaluate the satisfaction of the mother. Hence, the need for longitudinal qualitative research. In my opinion this would yield good results when past experiences would show which improvements were helpful and which were not. NICE standards (2010), specify the use of surveys. We can incorporate these surveys after consideration with the midwifery officer. Mother-nurse-infant interaction Because of the complexity of illness, parents of critically ill infants are anxious and fear the worst with every visit to the NICU. Strategies need to be adapted to decrease maternal anxiety while supporting the needs of these infants. (Nicholas-Sargent 2009). Nurses play a vital role in helping parents throughout the stressful and challenging experience of the NICU by developing therapeutic relationships and providing emotional support. These approaches enable parents to feel more supported, more involved, confident, and more effective as parents of their vulnerable newborn. The experience of parents in the NICU occurs during an emotionally intense period fraught with anxiety, stress, depression, and feelings of hopelessness. Therefore, Nicholas-Sargent (2009) suggests that, it would be vital to do an NICU orientation for expectant parents with a high risk of giving birth to a premature infant or a compromised newborn. Supporting and facilitating their parenting role will help decrease their stress, strain, anxiety, and depression. Lee et al (2008), nurses need to respect the cultural preferences of mothers as this would promote desired health outcomes. This would aid in meaningful, holistic and individualized care. According to Nicholas-Sargent (2009), personalized one-to-one as opposed as opposed to group support would be helpful. In addition Nicholas-Sargent (2009), suggests that nurse education is needed to improve the awareness of the impact of the counselling service. However, the service needs to be more flexible due to fluctuations in the health condition of the baby. In fact, what we notice is that mothers would require counselling at different stages of the hospitalization. Therefore, if the service was refused once, it may still mean that mothers would need it at some other point in time. Nicholas-Sargent (2009), further suggests that the counselling service would be extended to the whole family from the hospital as well as in the community., Both the DH (2009), and NICE (2010) highlight the importance of Family-Centered Care (FCC) views the family as the ‘child’s primary source of strength and support’ and allows for collaboration, respect, and support with the parents and family during all levels of the service delivery. To foster participation in care for the infant, unrestricted visiting hours should be encouraged for the nuclear family of the neonate. In Malta, visiting hours are restricted to parents only due to increase in cross infection when family members were allowed to visit for 1 hour everyday during the day. However, timing of care may still be arranged to facilitate parents’ participation. In addition, special moments such as baby’s first time off CPAP (continuous positive airway pressure) needs to take place during parents’ presence. Cockfort (2011), highlights that missed opportunities to involve parents in care, heighten anxiety and can create a sense of sadness and loneliness . Information for mothers Mothers vary in the amount of information they can assimilate under stress. Therefore identifying parents’ feelings through active listening and observing will help us to pick up on parents cues and respond appropriately in order to provide parents with accurate and clear information (Fenwick et al 2008). Nicholas-Sargent (2009), adds that, information regarding the health status of the baby needs to be give in a timely provision. Parker (2011), recommends the access to certified interpreters for non-English speaking parents to enable them to ask questions and get the information they need as well as information regarding the counselling services. Likewise, an updated information board at the infant’s bedside helps mothers retain information while feeling welcome at the bedside. In my opinion, these interventions create an environment that facilitates maternal- infant attachment by promoting maternal competence with meaningful positive parenting skills and fostering partnership in care.. Conclusion In summary, the findings showed that parents of infants admitted to the NICU experience stress, depression, anxiety, and feelings of powerlessness, hopelessness, and alienation within the environment of the NICU. These situations are often overwhelming and catastrophic for the mothers keeping in mind that the process of motherhood is a protecting and loving phenomenon. Therefore mothers should participate in the care of their sick, fragile infant in the NICU through mother-infant interaction. Nurses need to be supportive and informative in dealing with parents in the NICU. Therefore, the need for parents to be given the access of interpretation by certified interpreters in order to overcome language barriers has been identified. Further, information and emotional support is required throughout the stay in the NICU, However, it was further found that information in preparation for discharge planning is vital. This enhances parental knowledge and decreases stress, which promotes more effective parenting. Further, as understanding of the parents’ experience of having an infant admitted to the NICU increases, nurses will be better prepared to meet parental needs and alleviate parental suffering. Providing holistic, developmentally supportive care and open communication with parents in this stressful experience is essential. Moreover, the need for family-centered care has been identified.

Kennedy is arguably one of Americas greatest U.S. Presidents. Don’t waste time! Our writers will create an original "John F. Kennedy One of Greatest U.S. Presidents" essay for you Create order Elected in 1960, he brought an energy and grace to the Oval Office (John F. Kennedy: World War II Naval Hero to President). John F. Kennedy, the 35th President of the United States, was assassinated in Houston, Texas on November 22, 1963. He was commonly known by his initials, JFK. John F. Kennedy possessed many qualities that helped him become a great President. He had incredible charisma, was highly competitive, a risk taker and he was very courageous. claim When President Kennedy was assassinated the United States became immediately immersed in a state of mourning for this great leader. John F. Kennedy was full of charisma. This was definitely part of his leadership style. He was able to win over the people of the United States with his charm and become one of the most well known Presidents. In an essay written concentrating on JFKs leadership qualities, it was written, What makes a charismatic leader different from others is his vision to encapsulate obedience of the followers. Using unconventional methods allows a charismatic leader to convince followers that they are not the ?normal leaders-they are new, different, and inspiring. Trust and credibility comes from the willingness of these people to sacrifice themselves for the betterment of people and organizations. Charismatic leaders usually have high follower expectations, and are able to encourage these expectations by using unconventional behaviours to establish credibility, sensitivity, and appeal (John F. Kennedy and His Leadership Style History Essay). A study of President Kennedy and his many traits could not overlook his competitive nature. One of the most common personality traits found among presidents is a highly competitive nature. This makes sense, as any person who wants to become a president has to be constantly striving towards the top. As a result of wanting to be president, John F. Kennedy was known as being highly competitive. Whether this was a simple game or the presidency of the United States, John F. Kennedy always put his heart and soul in what he did (John F. Kennedy Personality Traits). Data #1 He was highly competitive and rarely settled for anything in his life other than the best. Is this a continuation of competitive? John F. Kennedy, himself, stated There are risks and costs to a program of action. But they are far less than the long-rang risks and costs of comfortable inaction. data #2 JFK believed and lived by the thought that a person would not get anywhere unless they were willing to take risks. The trick is knowing what risks to take and what risks to not take. The Cuban Missile Crisis helped solidify ?risk taker as a trait of John F. Kennedy. Along with a series of other risks taken both in his presidency and during his election, John F. Kennedy was not adverse to taking risks when it benefited himself and his country (John F. Kennedy Personality Traits). Data #3President Kennedy knew, also, when not to take risks. Even though it caused problems with some of his staff, he did not back down. Many people admired John F. Kennedy for his courage and bravery. He exhibited these qualities even before he was elected President of the United States. Jack joined the U.S. Navy in 1941 and two years later was sent to the South Pacific, where he was given command of a Patrol-Torpedo (PT) boat. In August 1943, a Japanese destroyer struck the craft, PT-109, in the Solomon Islands. Kennedy helped some of his marooned crew back to safety, and was awarded the Navy and Marine Corps Medal for heroism (History.com Staff). Data #1 After he became president, JFK continued to exemplify the great trait of courage. At one particular time, he found himself at odds with the Soviet Union and its volatile leader, Nikita Khrushchev. After a U.S.-backed invasion of communist Cuba in April, 1961 ended in disaster at the Bay of Pigs, Khrushchev concluded that JFKs administration was weak. In the autumn of 1962, the Soviet Union began shipping nuclear missiles to Cuba, from there they could be aimed at t he United States from just a few hundred miles away. When JFK found out about these missiles, he imposed a naval quarantine on Cuba and pondered an invasion (SparkNotes Editors). Data #2 needs backing between these two datas. After two weeks, where the entire world was on the edge of nuclear war, Khrushchev finally agreed to remove the missiles, ending the crisis (SparkNotes Editors).Data #3 There is no doubt that his courage during this time in history saved our country many lives and much destruction. Most people considered John F. Kennedy to be a really good person. A lot of people liked him as President of the United States of America. His predominate characteristics helped him to win over many voters and citizens of the United States. His incredible charisma helped him foster the trust of the people. John F. Kennedys competitive nature drove him to constantly strive towards the top of whatever he was endeavoring. He was willing to be a risk taker knowing that he would not achieve his goals if he was willing to take the risks. The courage he exhibited in making the hard decisions was part of his nature and one that helped him to become a beloved President of the United States of America.

Fibre Reinforced Polymers Composites In Strengthening Of Structures - Free Essay Example

Aim The project aim is to identify the use of FRP (Fibre Reinforced Polymers) composites in strengthening of structures. The general process and methodology considered in achieving this objective is by externally bonding Fibre reinforced plastics to the metal structure/plate and thus testing the specimen under 3 point bend as well as 4 point bend tests. The preliminary report will focus on the project introduction, literature review related to the project topic, project plan and further to be carried out. Analysis of Tasks As mentioned the projectà ¢Ã¢â€š ¬Ã¢â€ž ¢s main focus is strengthening of structures. So the question is why is there a need for strengthening of structures? The reason behind the strengthening of structures is that the structure will be able to support greater magnitude of loads than the values for which the structures are originally designed. Strengthening may become necessary in course of time in order to overcome the damage caused due to environmental factors such as corrosion as well as fatigue cracking. The method of bonding reinforcement represents an attractive solution to the problem as it can be achieved with relatively small impact on the structure. The next stage of the preliminary thesis will focus on the literature review. The literature review section is divided in to two sections firstly it will focus on the topics related to the Composite Materials, which will involve the following topics. Don’t waste time! Our writers will create an original "Fibre Reinforced Polymers Composites In Strengthening Of Structures" essay for you Create order Definition of Composite Material Classification of Composite Materials Types of Matrix Types of Reinforcement Advantages and Disadvantages of Composite Materials Manufacturing of Composite Materials The next section of the literature review will focus on the topics related to strengthening of structures. For this section following topics will be considered. Different Methods for Structure Strengthening Different Methods for Structure Strengthening using FRP Composites. The preliminary thesis will also look at the comparison between the structural strengthening using FRP Composites and Steel plates. This will help in giving a suitable reason as to why Composites are preferred over Steel plates for structural strengthening. Composites are considered as one of the most promising material for reducing the weight as well as increasing the strength of the material. The theory of hybrid material has been successfully exploited when studying sandwich panel technology. Now the concept of integrated multi materials is extended to a wider variety of structures, components and applications. Fibre reinforced plastics (FRPà ¢Ã¢â€š ¬Ã¢â€ž ¢s) have been successfully used for the post strengthening of structures over a number of years. The design and manufacturing of composites has led to its application in variety of industries such as automotive, aerospace, sporting goods, construction and in the marine as well as oil and gas industries. Moreover the method of bonded reinforcements also comes into account when there have been cases where errors in design or construction of a structure have questioned safety aspect. This can be achieved by externally bonding reinforcements at a cost of very small impact to the structures. Project Time-Line (Gantt chart) Literature Review Composite Materials Composite materials also known as composites are defined as a combination of two or more materials to give a unique combination of properties [1]. This definition is very general and thus includes metals, alloys, plastic co-polymers, minerals and wood. A material is only classified as a composite if the material satisfies the following conditions [2]: The material must be manufactured It should consist of two or more physically and/or chemically distinct, suitably arranged or distributed phases with an interface separating them. The characteristics of the composites are not depicted by any of the components in the isolation. Fibre reinforced composite materials differ slightly from the general definition because in this FRP the constituent materials are different at the molecular level and at mechanically separable. However the final material properties of the composite are better in comparison to that of the constituents. The figure 1 below gives a basic idea of how the structure of composite material looks like. The composites can be classified as fibre reinforced, particle reinforced, dispersion strengthened and laminates composites. Figure Structure of Composite Material [https://resources.edb.gov.hk/~s1sci/R_S1Science/sp/en/syllabus/unit14/new/images/s.gif] The composite material consists of two main elements the matrix and reinforcements (fibre). The classification of Composite materials is as shown in figure 2. Composite Materials Matrix Reinforcements Polymer Metal Ceramic Particle Reinforcement Fibre Reinforcement Structural Reinforcement Laminates Long Fibre Short Fibre Preferred Orientation Random Orientation Bidirectional Unidirectional Preferred Orientation Random Orientation Figure Classification of Composite Material Types of Matrix There are three main types of matrix considered when studying composites materials namely Polymer, Metal and Ceramic. Polymer Matrix composites are the most common types of matrix composites. They are also known as FRP (Fibre reinforced polymers). The resin used in here is polymer based combined with a variety of fibres such as Glass, Carbon and Aramid as reinforcements. Metal Matrix Composites are mainly used in the automotive industry. The materials use a metal for example Aluminium as the matrix which is then reinforced with fibres such as silicon carbide. Ceramic Matrix Composites are used in very high temperature environments. This type of materials uses Ceramic as the matrix and the matrix is then reinforced with short fibres such as Silicon Carbide and Boron Nitride. A matrix plays an important role in a Composite structure. There are several functions of Matrix most of which are very important to the satisfactory performance of the structure. The following points outline the important functions of the matrix. The matrix binds the fibre together and thus transfers the load to the fibres. The matrix provides the rigidity and shape to the structure. The matrix isolates the fibres such that each individual fibre can perform separately, due to this crack propagation process slows down. The surface finish quality of the structure is provided by the matrix. The matrix acts as a protection to the reinforced fibres from chemical attack and mechanical wear and tear. The type of material selected as matrix affects the ductility and failure mode of the structure together with the fibreà ¢Ã¢â€š ¬Ã¢â€ž ¢s compatibility. Types of Reinforcements The other constituent in the composite material is called the Reinforcement. This gives the composite the necessary strength and stiffness. The structure of the reinforcement is thin rod like. The most commonly used reinforcements are Glass, Carbon, Aramid, and Boron fibres. The diameters of these fibres range from 5 µm to 20  µm. [1] Due to the thin diameter of the fibre, the fibres are flexible and can be formed easily into any shapes. Fibres can come into many forms such as continuous fibre, discontinuous fibre, short fibres, long fibres, organic fibres and inorganic fibres. Fibre brings out the high performance of the material; this is due to three important characteristics of the fibres. The orientation of the fibres also has an impact on the performance of the composite. The fibres can be unidirectional, cross ply or random in its arrangement. Small diameter in comparison to the grain size. As a result of this higher fraction of theoretical strength can be attained. High aspect ratio (length/diameter); this allows a larger amount of load to be transferred. High degree of flexibility. The main functions of fibres are as listed below [1]; To carry the load. Hence fibres are made from materials with high tensile strength and high elastic modulus. Provides strength, stiffness, thermal stability and other structural properties in the composites. Provide electrical conductivity or insulation, depending on the type of fibre used. Advantages of Composites Composites are designed to perform in applications which require lighter weight and higher performance. The advantages of using composites are listed below. High resistance to Corrosion; due to this the application in marine, infrastructure and chemical is very good. High specific stiffness and high specific strength; this gives a weight reduction so is used for the application in aerospace, automotive and manufacturing of sporting goods. The impact resistance is high compared to metal. Higher fatigue strength. Unidirectional carbon/epoxy composites have good fatigue strength of almost 90% of its static strength. Composite materials offer increased amount of design of flexibility. For example the coefficient of thermal expansion of composite can be made zero if suitable constituents and lay up sequence is selected. As the coefficient of thermal expansion is relatively low compared to metals, the composite structure thus provides a good dimensional stability. Also due to the design flexibility, composite materials can be formed into any shapes. Process cycle times and costs are also reduced because of the use of composites in production of net shape and near net shape parts. Composite materials dampen the vibrations an order of magnitude better than metals. Glass reinforced and aramid reinforced composite meet the FAA and JAR requirements for low smoke and toxicity and thus are used in interior panels of aircrafts, stow bins and galley walls. Disadvantages of Composites There will always be limitations to the benefits of the composites. The disadvantages are as listed below. Weaker in transverse direction and low in toughness. Material cost is high compared to that of steel and aluminium. The lack of high volume production limits the wide spread use of composite materials. However this is changing as modern production methods such as Pultrusion, Resin transfer Moulding and other methods have been automated to increase the rate of production. The knowledge through books and database is limited when comes to designing parts with composite. Composites absorb moisture, which affects the properties and dimensional stability of the composite. Difficult to join together with other material due to its anisotropic properties and high sensitivity to damage. For example when drilling holes for mechanical fastening. Brittle like behaviour. Difficult to repair as most composites use thermo set matrices that can not be re shaped. On the contrary thermoplastics can be repaired how ever they are rare [4]. Solvent resistance, chemical resistance and environmental stress cracking of composite depend on the properties of polymers. Some polymers have low resistance to the solvents and environmental stress cracking[1]. Manufacturing of Composite Materials Before looking into manufacturing of composite materials; it is important to look at manufacturing of fibre performs briefly. Fibre performs is how fibre are manufactured before being bonded to the matrix to form a composite material. Fibre performs are often manufactured in sheets or filaments in case of spraying applications. The fibre manufacturing process is carried out by adopting the technique used in textile industry. The techniques used are weaving, knitting, braiding and stitching [5]. The manufacturing process of composite material in general can be divided into two main processes. Prepreg Moulding Wet Moulding PrepReg Moulding The process of prepreg moulding can be further categorized as: Bladder Moulding Compression Moulding Autoclave/Vacuum bag Moulding Mandrel Wrapping [6]Bladder Moulding: In this process the sheets of prepreg material are laid up and placed in female style mould along with a balloon like bladder. The mould is then closed and placed in the heated press. Eventually, the bladder is pressurized which then forces the layers of material against mould walls. The part is then cured and removed from the hot mould. The process is ideally suited for complex hollow shapes. Also the process has great cost to performance balance. Typical example of equipment using bladder moulding technique is the manufacturing of tennis racquet. Average cure cycle range is 15-60 minutes. Compression Moulding: A process where a à ¢Ã¢â€š ¬Ã…“performà ¢Ã¢â€š ¬? or à ¢Ã¢â€š ¬Ã…“chargeà ¢Ã¢â€š ¬? of single moulding compound (SMC) or bulk moulding compound (BMC) or sometimes prepreg fabric is placed in the mould cavity. Once the mould is closed, the material is compacted and cured inside by heat and pressure. The process also offers excellent detailing for geometric shapes. The average cure cycle range is 2-20 minutes. The tooling is process is often more expensive. Auto Clave/Vacuum Bag Moulding: The figure below gives an idea of vacuum bagging for prepreg lay-up process. Figure Vacuum bagging for prepreg lay up process [https://www.highcomp.no/design/bilder/vacum/vacum.gif] Once all the prepregs are laid out in the desired sequence, vacuum bagging preparations are set up as per the figure 3 for curing of the part. First step is application of release film on the top of all the prepreg. The release film is a perforated film that allows captured air, excess resin and volatiles to escape. Secondly is the application of bleeder on top of release film; it is a porous fabric that absorbs moisture and excess resin coming from stack of prepregs/laminates. Thirdly is the application of non porous and non-perforated film on top of bleeder. After this a breather layer is applied; this is a porous fabric which creates even pressure around the part and at the same time allowing air and volatiles to escape. Then final layer is of vacuum bag. The vacuum bag is an expendable polyamide film. The film is sealed on all sides of laminate using a seal tape. A nozzle is inserted into the vacuum bag and is then connected to hose vacuum pump for creating vacuum. Mandrel Wrapping: In these process sheets of prepreg material is wrapped around steel or aluminium mandrel. The prepreg material is compacted by nylon or polypropylene cello tape. Parts are cured by hanging in the oven. Once the curing process is completed, the cello and mandrel are removed which results in a hollow carbon tube. Advantages of prepreg lay up process are that it is simple process when manufacturing complex parts. Also strong and stiff parts can be fabricated using this process. Also allows production of high fibre volume fraction. Prepregs usually have more than 60% fibre volume fraction. Limitations of the process being that labour is intensive as a result of which the process is not suitable for high volume production applications. Also parts manufactured by this process are very expensive. Wet Moulding Wet moulding process can be divided into following processes. Wet layup Spray Up process Filament winding Pultrusion Resin transfer Moulding (RTM) Resin transfer moulding under vacuum (VARTM) Wet Lay-up: in this process a fabric is placed in open mould which is then hand saturated with wet resin. The curing occurs normally at room temperature. However it can be cured at higher temperatures based on the heat resistance of the mould. The advantage of this process is that the material cost and tooling cost is low. Because of this the process is considered as low tech process. Spray-up process: The processing steps are similar to that of the wet lay-up process except for the method of creating the laminates. The basic steps are as follows [1]. The mould is waxed and polished for easy de-moulding Gel coat is applied to the mould surface and allowed to harden before building any other layer. The barrier coat is applied to avoid fibre print through the gel coat surface. Oven curing of barrier coat. Mixing of resin with fillers and the mixture is then pumped to a holding tank. Spraying of resin, catalyst and chopped fibres on the mould surface. This is done with the aid of hand held spray gun. The spraying is carried out in typical pattern to create uniform thickness of the laminate. A roller is then used in order to make the fibre and resin material compact as well as create a smooth and even surface. The laminate is then cured in the oven. The part is then de-moulded and sent for finishing work. The process of spray lay-up is very economical, maximizes the use of low cost tooling as well as low cost material systems however it is not suitable for making parts that have high structure requirements, fibre volume fraction can be difficult to control as well as the thickness. The surface finish on both the sides is not same. Also dimensional tolerance is poor. Filament Winding: This is a process in which resin-impregnated fibres are pulled and wound over a rotating mandrel at desired angle. The fibre pulled is from a wet bath of resin. Curing occurs at room temperature or higher temperature. The performance is limited and it is difficult to obtain uniform fibre distribution and resin content through out the thickness of the laminate. The process is very suitable for tubular parts such as pressure vessels. Figure Filament Winding Process [https://www.thaicomposites.com/images/filament-winding.gif] The advantages of this process being its ability to utilize low cost raw material and low cost tooling systems. It can be automated for the production of high volume composite parts. The figure 4 gives an indication of the filament winding process. Pultrusion: As the name suggests, it is a process which will have pulling and extrusion (cutting). In this process resin impregnated fibres are pulled through to make a part. Saturated material is pulled through a heated closed die and cured while continuously moving through the die. The figure 5 gives an indication of the process. Figure Pultrusion process [https://www.ultrafiberglass.com/pultrusion%20process.jpg] The advantage of pultrusion process is that it is a continuous process and can be completely automated to get the finished product. The process is suitable for making high volume composite parts. Utilizes low cost fibre and resin systems thus provide a low production cost of products. The limitations being that the thin wall parts, tapered and complex parts cannot be produced. Resin Transfer Moulding A resin and catalyst are placed in two separate tanks A and B. A release agent such as gel coat is then applied to mould for good surface finish. The preform is placed inside the mould and the mould is then clamped. The mould is then heated to a specified temperature. Mixed Resin is then injected at selected temperature and pressure. Vacuum is also created to remove air bubbles as well as assist in resin flow. The injection continues until the mould is completely filled. The vacuum is turned off. The pressure inside the mould is increased to ensure that remaining porosity is collapsed. After curing for certain period of time depending on resin, the composite part is removed from mould. In this process, fabrics are placed in to a mould and then wet resin is injected. Resin is pressurized and is then forced into the cavity which is under vacuum. In the VARTM process resin is completely pulled in to cavity under vacuum. This moulding process allows precise tolerance and detailed shaping, however this may result in at times failure to fully saturate fabric leading to weak shape in the final product. The figure and steps following the figure describe the process. Figure Resin Transfer Moulding [https://www.ctihuatai.com/index.files/rtmstatic.gif] Strengthening of Structures The next stage of literature review will now focus on the strengthening of structures. As explained earlier the need for strengthening of structures; it is important to look at first the different methods adopted in order to strengthen the structure. The structure strengthening methods include the following. Span Shortening Pre-stressed Concrete Section Enlargement Structure Strengthening using FRP Composites. Span Shortening This is method in which length of a beam is shortening. This is achieved by installing additional supports underneath the existing members. Materials used in this process are mainly structural steel members and cast in place reinforced concrete members. The members are connected mechanically using bolts and adhesive anchors. Span shortening reduces the deflection in the beam. This can be proved by means of simple calculation. P1ÃŽÂ ´1 Let us consider a beam of length à ¢Ã¢â€š ¬Ã…“L (m)à ¢Ã¢â€š ¬? under a load P kN undergoing a 3 point bend test. l1 Where ÃŽÂ ´ is the deflection in the beam. Let us consider a pair of equations in order to calculate deflection in the beam. ; If ratio of the deflection is taken in to account, and doubling the span length meaning l2 = 2l1. Then, Then ÃŽÂ ´2 = 8 x ÃŽÂ ´1; this means that central deflection will become 8 times. So to conclude the method shorter the span, less deflection will occur at the centre. Pre stressed Concrete Pre stressed concrete is a method used for overcoming concreteà ¢Ã¢â€š ¬Ã¢â€ž ¢s natural weakness in tension. Pre-stressing tendons generally made of high tensile steel rods are used to provide clamping load that generates compressive stresses which balances out the tensile stress that would be experienced by the concrete beams due to bending [7]. The process of pre stressing can be achieved in three ways: pre tensioned concrete, bonded or un-bonded post-tensioned concrete. However the method is mainly used for civil engineering and construction projects. The figure below gives an indication of the method. Figure Pre Stressing Method [https://www.fhwa.dot.gov/BRIDGE/pt/images/pt102.gif] Section Enlargement In simple terms, it is when the second moment of area is changed. The method involves placing an additional bonded reinforcement concrete to an existing structure member in the form of an overlay or a jacket. The main advantage of this technique is that it increases the load bearing capacity or stiffness. The technique reduces bending and shear forces on overstressed beams. Structure Strengthening using FRP Composites Fibre reinforced polymers are applied to strengthen structure. There method can be primarily divided in to two categories. One is the strengthening of structure at manufacturing phase and other is after manufacturing. The technique used to strengthen structure at manufacturing phase is known as Near Surface Mounted Reinforcement (NSMR) and the strengthening of structure can be achieved once the manufacturing is completed is by external plate bonding method. Near Surface Mounted Reinforcement Near surface mounted reinforcement is one of the latest and most promising techniques to be considered when strengthening concrete structures. Using FRP instead of steel in this technique has many advantages such as its better resistance to corrosion, quick and easy installation due to light weight. When compared with external bonding method, the NSMR has many advantages such as amount of site installation work is reduced for example removal of plaster, etc. second advantage being that NSMR is less prone to de-bonding from concrete substrate. NSMR bars can be easily anchored into adjacent members to prevent failures due to de-bonding. This feature is very important when considering flexural strengthening. NSMR bars can be easily pre-stressed. As the bars are covered by cover of concrete, so they are less exposed to accidental impact or mechanical damage such as fire or wear and tear. As the NSMR technique is new, the knowledge on this technique is limited than that of externally bonded reinforcement. In recent studies CFRP (carbon fibre reinforced polymer) NSM reinforcements have been widely used to strengthen structures. The following general steps must be performed during the strengthening. Sawing up slots in concrete cover, depth of the structure is dependent on the product used. After sawing of slots, careful cleaning is required. If using an epoxy system, the slots where the bars are to be installed must be dry before bonding. If cement system is used then the surface must be wet. Adhesive is applied in the slot when using epoxy system or cement mortar is used when using cement system. The figure below gives an indication of the technique. Figure Near Surface mounted Reinforcement technique [https://msw.mcmaster.ca/~koranyy/Photos/NSM-vertical.jpg] In the above figure it can be seen that a carbon fibre rope is placed in the centre of the brick wall and an epoxy paste is applied. The figure on the left is for vertical reinforcement and the figure on the right is for horizontal reinforcement. The second part of the images is the finished version of structure once the method is completed. The application of this technique is mainly on flat surfaces and is suitable for strengthening in bending. The process is also helpful in increasing the shear capacity of the beams. The next method considered for structure strengthening using FRP composites is external plate bonding. However it is first important to compare the advantage of using composites over steel plates. These are explained in the next segment of the report. External Plate Bonding The general principle of external plate bonding method is that in this method transfer of stresses takes place from the structural element to the additional plates that are adhered or bolted. Whilst strengthening structure many problems are faced such as. Load Increases: Structure with externally bonded plates has capacity to accept higher live loads for example in factories where heavy machines are installed. External plate bonding also reduces deformation and is also helpful where vibrations are an issue. Damage to Structural Parts: it can be utilized in cases where the building has been damaged due to fire or vehicle collision. Improvement in suitability: This can be achieved by limiting deflection and reducing crack widths and stresses. Modification of Structural System: Plate bonding provides a cost effective solution where structure has been weakened by removal of walls and columns or opening cuts. Errors in planning or construction: Plate bonding provides solution to earlier design errors and calculation errors. In general terms external plate bonding can reduce deflection thus limit cracking as well as increase the load bearing capacity and also increase the flexural strength and finally improve resistance to shear in certain cases. As the method of plate bonding can be achieved by both using Composites as well as steel plates so it is important to understand the advantage of composite over steel plates. This analysis will be carried on three grounds namely technical, practical/application and Economic. The table on the next page summarizes the technical differences between the composite and steel plates Composite Steel Plates High tensile strength of Carbon fibre (5650N/mm2) Tensile strength of steel is (235 N/mm2) No corrosion Highly prone to corrosion Strength to weight ratio is higher Strength to weight ratio is lower Table Technical differences between Composite and Steel Plates When performing practical application on site; installation of steel plates requires an extensive amount of work such as drilling holes in plates, wrapping plates and bolting the plates. Where as the composite plates would require very limited work such as bonding to the metal plate using an epoxy. Table 2 summarizes the economic differences Potential Cost Composite Steel Plates High Low Volume Typically 10-50% of steel Relatively high Adhesive smaller area of plates required so less adhesive Area of plates is high so higher amount of adhesive Preparation Off site On site Limited Limited Extensive Extensive Labour Requirement Low High Equipment Low High Temporary support None Yes Time Fast Slow Table Economic Differences between Composite and steel plates The application of the plates externally can be varying such as if the surface is horizontal than FRP is applied horizontally or in the U shape. If the structure is a circular column then FRP is applied by wrapping around it. Wrapping sheets have fabrics in same direction or bi-directional. One thing to be considered when using FRP is that it needs to be protected from fire. An FRP plate applied to the bottom of structure (tension face) increases the strength of beam and reduces deflection. Where as application of FRP strips attached in U shape around the sides and bottom of beam increases shear resistance. Wrapping of sheets around column results in higher strength and restrains lateral expansion of columns. The figures below give an example of application of FRP composite to structure.

Discussion The project is currently in its research phase. The topics covered in the literature review section of the report are vital as it is important to gain knowledge about the subject and understand its applications in the real engineering world. The future work in the project will involve an additional literature review for structural strengthening and the next stage will be to set up a meeting with the supervisor to discuss the experiment as to what needs to be performed. Once this is completed the project plan will be reviewed to meet the final submission date of the thesis as mentioned earlier in the deliverables section. To conclude the test to be carried out for this purpose will be a 3 point bend test and 4 point bend test and thus the results will be concluded.

Ands Boniface was born in Manila in 1863, the son of a government official. When both his parents died in the sasss, he left school to support his five brothers and sisters. By the mid-1 8805, he had become a fervent Filipino nationalist. When Joss Racial established the Alga Filipino in 1892, Boniface was one of its first members.After the Spanish arrested Racial in July 1892, Boniface decided that the Philippines would only achieve independence through revolution. On July 7, he founded the Justinian, a secret society open to both peasants and the middle class that employed Masonic rituals to impart an air of sacred mystery. It insinuated itself into the community by setting up mutual aid societies and education for the poor. By 1896, the Justinian had over 30,000 members and functioned at the national, provincial, and municipal levels.Following the execution of Racial in 1896, Boniface proclaimed Filipino independence on August 23, 1896. This time, the Spaniards moved against him, forcing his flight to the Marking mountains, while other forces headed y Emilio Continual were more successful and won control over some towns. When Boniface tried to rein him in, Continual ordered him arrested and charged with treason and sedition. He was tried and convicted by his enemies and executed on May 10, 1897. Today he is regarded as a national hero of the Philippines.Emilio Action Name: Emilio Action (December 15, 1875 to April 16, 1899) Born: December 15, 1875 Father: Marino Action Mother: Josef Dijon Better Known: Brain of the Justinian Emilio was born in Torso, Manila on December 15, 1875. When his father, Marino Action died, his mother Josef Dijon, a midwife, had to work harder o support his studies. Later, he was forced to live with his uncle, Don Jose Dijon, who enrolled him at the San Juan De Lateran College. Then he transferred to the University of Santos Tomato to take up Law. His studies however, were interrupted when he joined the Justinian at the start of the Philippine Revolution in 1896. His sad experiences with his Spanish classmates, his sensitivity to the flight of his people, and his readings about the Spanish injustices led him to do so against the wishes of his mother and his uncle. He was only 19 years old, but became one of the ablest leaders of the Justinian. To Boniface, he was an adviser, a secretary, and a fiscal. He edited the Nag Callahan, the newspaper of the Justinian which informed the people of the aims and activities of the association.He wrote the Sartorial, the primer of the Justinian which contained its rules and regulations. He supervised the manufacture of gunpowder. Thus, he was called the Brain of the Justinian. Action was also a poet. His greatest poem was A La Patria, inspired by Racals Ultimo Adios. It was signed Dimes-law, Casinos pen name. In one of the battles in Majesty, Laguna, Emilio Action was wounded artistically; he died on April 16, 1899 at the age of 24. Application Mamboing Martian (July 22, 1864 -? May 13, 1903) Application Mamboing was a Filipino political philosopher and architect of the Philippine revolution.He formulated the principles of a democratic popular government, endowing the historical struggles of the Filipino people with a coherent ideological orientation. Application Mamboing was born in Tale, Tanana, Battings, on July 22, 1864. His parents belonged to the impoverished peasantry. He studied at the College De San Juan De Lateran in 1881 and at the University of Santos Thomas, here he received the law degree in 1894. During this time he earned his living by teaching Latin and then serving as copyist in the Court of First Instance in Manila.In 1 896 Mamboing contracted an illness, probably infantile paralysis, that deprived him of the use of his legs. When the Justinian revolt broke out late that year, the Spanish authorities arrested him. Unknown to many, Mamboing was already a member of Joss Racals reformist association, the Alga Filipino. And though as a pacifist reformist, he was at first skeptical of Andrea Benefactions armed uprising, Mamboing later became convinced of the peoples almost fanatical desire for emancipation. Subsequently, he turned out subversive manifestos appealing to all Filipinos to unite against Spain.In May 1 898 Emilio Continual summoned Mamboing to act as his adviser. Mamboing formulated the famous decree of June 1 8, which reorganized the local government under Filipino control. His policy throughout the struggle can be epitomized by a statement in that decree: The first duty of the government is to interpret the popular will faithfully. Mamboing was also instrumental in supervising the proper administration of justice, the election of delegates to he revolutionary congress, and the establishment of the mechanism of the revolutionary government itself.When the revolutionary congress was convoked in Bargains, Mallows, Vulcan, on Septet. 15, 1898, Mamboing found himself opposed to the plans of the wealthy bourgeoisie to draft a constitution. He believed that, given the emergency conditions of war, the function of the congress was simply to advise the president and not to draft a constitution. Defeated by the majority, Mamboing then submitted his own constitutional plan, based on the Statutes of Universal Masonry. It was rejected in favor of a composite draft submitted by Feline G. Cauldron, which became the basis of the Mallows Constitution of the first Philippine Republic.Ambits conflict with the conspiracy of property owners and the landlord class in the congress led to his eclipse in 1899 as Gondolas trusted adviser the only competent thinker and theoretician in the Continual Cabinet. Mamboing succeeded in exposing the vicious opportunism of the Pattern-Bemoaning clique, who were tying to gain control over, and to profit from, the financial transactions of the revolutionary government. When the Continual camp fled from the advancing American forces, Mamboing was captured on DCE. 0, 1899. Still refusing to swear an oath of allegiance to the U.S. Government and continuing to support the insurgents in their ideological struggle, he was deported to Guam in 1901. He died on May 13, 1903. Ambits chief work, La Revolution Filipino, a reasoned analysis and cogent argument concerning the ideological implications of the revolution against Spain and the resistance to the American invaders, reveals the progressive and democratic impulse behind his thinking. He always tried to mediate between the peoples will and the decisions of their leaders. He was a selfless and dedicated patriot.

Pierre Trudeaus Just Society Essays - Pierre Trudeau,

Pierre Trudeau's Just Society In 1968, Pierre Elliott Trudeau had just become Canada's fifteenth prime minister. "I've always dreamt of a society where each person should be able to fulfill himself to the extent of his capabilities as a human being, a society where inhibitions to equality would be eradicated. This means providing individual freedoms, and equality of opportunity, health, and education, and I conceive of politics as a series of decisions to create this society." Trudeau, who resigned as prime minister in 1984, died on September 28, 2000, at the age of eighty. He believed that the nation must be strong enough to withstand the overwhelming economic and cultural pressures from its giant neighbor, the United States, and he believed in a "Just Society," one of his favorite phrases that held many meanings for him. The concept of a Just Society was never merely a convenient phrase; it was the inspiration for Trudeau's deepest feelings. He believed that the ever- widening gulf between rich and poor at home and in underdeveloped countries should be reduced. He thought it was the government's responsibility to provide equal status, equal opportunity, and fair treat-merit for all. As justice minister he introduced legislation that broadened grounds for divorce and abortions and abolished penalties for homosexual acts between consenting adults, with the famous remark, "The state has no business in the bedrooms of the nation." One of Trudeau's first moves as prime minister was to make Canada a bilingual country, with the Official Languages Act, which gave French and English equal status by law. Trudeau also "brought home" the Canadian constitution with the Constitution Act of 1982, rectifying an anomaly from the previous century that required the amending process to be approved by the British Parliament. He incorporated a Charter of Rights and Freedoms into the Constitution, which enshrined French and English education rights across the country; created PetroCanada, Canada's own oil company; instituted the controversial National Energy Program, which extended federal government control of the gas and oil industry; appointed the first woman to the Supreme Court of Canada and the first female governor-general; and introduced new employment and educational opportunities for the young. "Not all his policies were well received," recalls Ivan Head, Trudeau's former principal adviser on foreign policy. "His National Energy Program in 1980, designed to increase Canadian ownership of the oil industry from 15 percent to 50 percent, to introduce conservation measures, and to revise the division of oil revenues between the producing provinces and the federal government created immense controversy. The province of Alberta and the United States government both retaliated against what they regarded as `anti-Alberta' and `anti-American' actions. Trudeau was "a breath of fresh air for what was then a very staid society, which has undergone tremendous change because of his impact." Trudeaumania was the Nickname given in early 1968. Trudeaumania continued during the subsequent federal election campaign and during Mr. Trudeau's early years as Prime Minister of Canada. Many young people in Canada at this time were influenced by the 1960s counterculture and identified with Trudeau, a young, energetic, nonconformist. They were dazzled by Trudeau's charm and good looks, and a large fan base was established throughout the country. He would often be stopped in the streets for his autograph or for a quick photograph. Trudeau was also admired for his laid-back attitude and his celebrity relationships; in that word's prevailing use at the time, describing a modern, hip and happening person, he was described as a swinger. Trudeaumania began to fizzle after Pierre Trudeau married Margaret Sinclair in 1971, but he is remembered to this day as one of Canada's most polarizing politicians and prime ministers: fondly recalled by many Central and Eastern Canadians while at the same time unpopular in the western provinces and among conservative thinkers and Quebec nationalists. Official bilingualism is the term used in Canada to collectively describe the policies, constitutional provisions, and laws which give English and French a privileged status over other languages in Canada's courts, parliament and administration. In addition to the symbolic designation of English and French as official languages, official bilingualism is generally understood to include any law or other measure which: . mandates that the federal government conduct its business in both official languages and provide government services in both languages; . encourages or mandates lower tiers of government (most notably the provinces and territories, but also some municipalities) to conduct themselves in both official languages and to provide services in both English and French rather than in just one or the other; . places obligations on private actors in
