The Experience Of Becoming A Family - 1638 Words
Endeavoring to become a family health nurse has been a long and rock-strewn journey. Yet, like climbing a mountain with its downfalls and peaks, I have become more astute in managing circumstances and have developed a new understanding of what a family nurse embodies. The purpose of this paper will be to illuminate the experience of becoming a family-oriented nurse and how I utilized my knowledge from Family Health course to achieve this outcome. I will deliberate on an event that summarizes my experience, what I have discovered about myself, applying themes from works of literature, and the development of future goals. I will then conclude with a brief summary of my comic manifesto. The Meaningful Experience of Practicing Family Healthâ⬠¦show more contentâ⬠¦This idea was further emphasized during an activity in week seven in which groups of students shared health-promoting practices that were based on their culture and upbringing (Appendix A). Such activity placed the complexity of relational practice into a simple picture in which one can visualize how the developed strengths and unique expertise of individuals were rooted by context. Indeed, in deterring from the attitude of the expert nurse to adopting the concept of shared expertise, I have noticed a decrease in my tendency to label families negatively, and instead, visualize their strengths and built partnerships. The integration of these discoveries into practice was reflected when the patientââ¬â¢s appetite plummeted. In his prolonged stay in the unit, I had witnessed his daughtersââ¬â¢ resilience and how they had encouraged their father in ways that others could not. I recalled asking them, ââ¬Å"What does he like to eat? Can you bring food from home? What does he normally do when he feels unwell and how has he or your family managed it?â⬠. In seeking their assistance I had hoped to develop meaningful interventions that best reflected the patientââ¬â¢s culture and life context (Doane Varcoe, 2005).

Understanding A Child Needs And Child Development - 851 Words
Understanding a child needs and the way to interact with them a key knowledge to create different ways for the child to development at their appropriate age level. In the beginning of the semester, I only have some knowledge of child development. I didnââ¬â¢t know the method of teaching a child are even to speak to them. After this class and participating in programs relating to children s development, such as Jumpstart, i slowly understand the importance of ways to express and take to the children. The environment that a child grows in affects a child in a certain degree that would either be negative or positive. For example, if a child is growing in a place that lack of space and material to manipulate, then the child will have lack of that skill he or she is supposed to acquire at a certain age and that will maintain for a lifetime. On the other hand, if the child have the spacious environment to implement play meaning that child would have enough material to develop the devel opmental skills that is appropriate for his or her age. In a classroom, it is best that there is enough materials for each individual that are able to use to reach the developmental skills. I think the most important thing that a classroom should have is natural lighting, which meaning that there should be windows. ââ¬Å"In early childhood centers located in spaces not originally designed for childrenâ⬠¦.create a safe, healthy, and engaging environmentâ⬠( Smith, 2013 p.9).

Letter to the George Bush Team to Visit City Florence Free Essays
Dear Sir, It is great honor for me to be a guide for George Bush in Florence. I will do my best to ensure that he remembers Florence as the most beautiful place on Earth and realizes why this city is literally a magnet attracting tourists from the most remote areas. Every person who is fond of art needs to visit this gorgeous spot at least once in his life. We will write a custom essay sample on Letter to the George Bush Team to Visit City Florence or any similar topic only for you Order Now Florence gets visited by tourists in the millions because it offers them an astonishing variety of scenes. Even though one day of being in Florence is by no means enough to grasp the whole feeling of the city, it can still create an overwhelming delight in the personââ¬â¢s heart, and make him thirsty to see more during the following visits. It is my goal to help George Bush get immersed into Florenceââ¬â¢s atmosphere from the very first minutes of the visit. He will be able to understand why Florence is one of the worldââ¬â¢s most enjoyable cities. He will never forget this beautiful experience and keep desiring to return here many times in the future. Due to the short length of the visit, I have decided to pick out the most interesting sites for the President. We will have time to visit only three places of interest, but I can assure you that they will all tell a great deal about the history of Florence and its uniqueness. In our city, we have enough monuments to keep a tourist occupied for years, but even a day is enough to understand that there is no similar place on Earth to Florence, no matter how much you look. I want to organize this excursion in such a way that George Bush realizes why Florence is considered the cradle of Renaissance. Many people know that Florence was the Italian city which gave birth to Renaissance, but very few of them can actually explain why. In order to be able to answer this question, one needs to get acquainted with the masterpieces of Renaissance artists. They do not have any analogues in the world; they are absolutely unique. Every piece of art created during that epoch breathes with the feeling of freedom and unlimited inspiration which knows no borders. I want to show such pieces of art to George Bush so that he hears them talk to him through ages. The first place of interest which we are going to visit will be The Casa Buonarroti, the house in which outstanding artist Michelangelo lived; then we will proceeded to Romanesque baptistery which is famous for scenes from Old Testament created by Lorenzo Ghiberti on its doors; and finally we are going to visit Brancacci Chapel the frescos of which were gradually painted by Masolino, Masaccio and Filippino Lippi, the most famous Renaissance artists. All of these places are very unique, and they can tell a great deal about the Renaissance epoch. The Casa Buonarroti is going to be particularly interesting for the President because this is the place where Michelangelo lived and created his masterpieces. There can be nothing more extraordinary than starting to visit to Florence from visiting the house of the perhaps the most outstanding artist of Renaissance. Even though Michelangelo did not step in his house for many centuries, it is possible to feel his presence there many years after. The house was transformed into a museum by one of Michelangeloââ¬â¢s relatives, Michelangelo Buonarroti the Younger, in 17th century. The museum not only has created work of Michelangelo, but also painting of other famous artists depicting the scenes from his life and his virtues. It is impossible to avoid visiting this museum during the visit to Florence. Romanesque baptistery is going to impress George Bush due to many reasons; first, it is one of the oldest buildings in Florence and thus tells a lot about its history; second, it would appeal to the Presidentââ¬â¢s interest in religion; third, it has scenes from Old Testament created by famous Lorenzo Ghiberti on its doors. Lorenzo Ghiberti is one of the most famous sculptors of his time. It is common truth that these days, some people would pass by this legendary building even without stop. Some young people do not appreciate these masterpieces as much as they should. However, Romanesque baptistery needs to be noticed and remembered by everybody because nothing can compare to Lorenzo Ghibertiââ¬â¢s creative work on its panels. The gates which he created into the baptistery were called ââ¬Å"gates to paradiseâ⬠by his contemporaries. One can easily tell which scenes from Bible the artist depicted. He worked most of his life on these pieces of art, and they impress tourists until these days. In the middle panel there is a scene of Jacob and Esau depicted. All of the characters of the Bible are painted in such a way as if they are alive and are almost going to jump off the panels. The last site which we are going to visit is Brancacci Chapel. It has very unique architecture and it famous for the frescos gradually painted by Masolino, Masaccio and Filippino Lippi. The history of painting frescos for this chapel is really impressive. In the beginning of 15th century a Florence ambassador to Egypt commissioned Masolino to paint the frescos for the cathedral. After completing some work, the famous artist charged his student Masaccio with this task, and Masaccio brilliantly coped with the part of the work which the master assigned to him. However, Masolino did not have a chance to finish the work entirely due to his death, therefore, the frescos remained unfinished until Filippino Lippi, another famous artist, added the last strokes to the paintings in the end of 15th century. This chapel will be particularly interesting for George Bush because it will tell him very much about the differences of styles of one of the most famous Italian painters of all times. One can easily capture slight differences between the strokes done by Masolino, Masaccio and Filippino Lippi because each of them had his own unique style. However, the frescos turned out completely extraordinary as the result of their combined work. I very much hope that the visit of George Bush to Florence turns out very enjoyable. All of the sites which I picked out for him are going to let him fall in love with Florence during one day, and look forward to going back soon. Bibliography. Art History Gardeners Art through Ages.

Essay on How does Heat Transfer Works Example For Students
Essay on How does Heat Transfer Works I chose the topic of heat transfer because I find it really intriguing to learn about. I wanted to look further into how heat from two substances reacts with one another through another material that was placed between them. I will be looking at how to calculate the rate of heat transfer in a one dimensional space. This means that I will only be focusing on two temperatures, one hot and one cold, and a medium of which the heat will pass through. External factors such as other temperatures and time will not be used as they are for three dimensional spaces. Heat is a type of energy that transfers between two pieces of matter that have different temperatures. There are three ways heat can be transferred. The first way is through radiation and the second is convection. The third way is through conduction which is when an object or material conducts the heat from one substance through itself and to another. This is the method I will be focusing on. As stated in the second law of thermodynamics, heat flows from the matter or objects with the higher temperature to the one containing lower temperature and is not possible from cold to hot. This will continue until both objects have reached a thermal equilibrium. At this point, one object does not contain a higher temperature than the other, so the heat transfer ends. The rate at which the heat is transferred depends on the composition of the material that separates the two temperatures. For example, the rate at which heat flows from hot water to cold water through a copper cup will be different than if the cup is porcelain. The rate that the heat energy is transferred is directly proportionate to the rate at which the temperature changes. Also, since the lower temperature is gaining the same amount of heat that the higher temperature is losing, the graphs of these two should be negative reciprocals of each other. The higher temperature ââ¬ËAââ¬â¢ will generally have a negative slope whereas the lower temperature ââ¬ËBââ¬â¢ will have a positive slope. When both A and B have the same temperature, as mentioned before, they have reached a thermal equilibrium and therefore will have a slope of zero as neither one is gaining or losing heat. This chart represents the increase and decrease in temperature due to the loss and gain of heat. It does not represent any set data and is not a completely accurate diagram. The heat that the hot water loses is gained by the cold water. This continues until the hot water is the same temperature as the cold water. At this point, neither one is warmer nor colder than the other, so the transfer stops, resulting in a gradient of zero. To start off, I have two variables to work with. The first variable is the difference in temperature of the two objects; in this case, it is water. The second variable is the composition of the material that is separating the two different temperatures. I have considered this variable because it is directly involved with the heat transfer as the heat energy is passing from one object, through the material, and into the second object. As mentioned before, heat flows from the region with the higher temperature to the region with the lower temperature. Let G represent the rate at which the heat is transferred through conduction. This should be equivalent to the temperature gradient of dT/dx , where T(x) is the temperature and x is the distance travelled in the same direction and the heat is flowing. G=dT/dx However, with the current equation, there is no variable for the area of which the heat is transferring through. It only states that the gradient of dT/dx is the rate at which heat is transferred. It implies that the heat transfer between two substances will be the same if the area is 5cm2 and if it is 5km2. Area is another variable that affects the rate at which heat transfers. The larger the area of a medium, the more heat is transferred because there is more surface area that is conducting the heat from one substance and into another. An example of this is a large window in a building compared to a smaller one. Rooms with large windows tend to be colder because more heat has been lost from there. G=A dT/dx dT/dx is the temperature gradient in the direction which is normal to the area. This equation includes the area (A) of the surface that the heat is passing through, but it does not factor in the conductivity of the material placed between the two substances. Let the variable c represent the thermal conductivity of the material involved in the transfer. G=K A dT/dx In addition, the second law of thermodynamics states that heat energy must flow from a warmer region to a colder one. A negative sign must be placed on the right side of the above equation since the heat is being transferred in the direction of increasing x values will result in a positive quantity. .uf1eb2ee37c20adaa25ca0e0a2cce839a , .uf1eb2ee37c20adaa25ca0e0a2cce839a .postImageUrl , .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text-area { min-height: 80px; position: relative; } .uf1eb2ee37c20adaa25ca0e0a2cce839a , .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover , .uf1eb2ee37c20adaa25ca0e0a2cce839a:visited , .uf1eb2ee37c20adaa25ca0e0a2cce839a:active { border:0!important; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .clearfix:after { content: ""; display: table; clear: both; } .uf1eb2ee37c20adaa25ca0e0a2cce839a { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:active , .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text-area { width: 100%; position: relative ; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:hover .ctaButton { background-color: #34495E!important; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uf1eb2ee37c20adaa25ca0e0a2cce839a .uf1eb2ee37c20adaa25ca0e0a2cce839a-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uf1eb2ee37c20adaa25ca0e0a2cce839a:after { content: ""; display: block; clear: both; } READ: Biology: The Thermodynamics of Protein-Protein Interactions EssayConduction heat flow ÃâT/Ãâx is negative if the value of x increases while the temperature decreases G=-k A dT/dx The equation, G=-k A dT/dx , can be altered to form another equation.

The area (A) is expressed in squared metres (m2). The temperature (K) is expressed in Kelvin. X is expressed in metres. The rate of heat flow is expressed in watts (W).

The equation for thermal resistance is: R= L/Ak L stands for thickness A stands for area k stands for thermal conductivity G=ÃâT/(L/Ak) G=Ak/L(T1-T2) These equations are measured in k/W which is equivalent to à °C/W. Using these equations, I can find the thermal resistance and the rate of heat transfer through a medium. Take for example, a large aluminum slate (k = 237 W/m K) of which the dimensions are 1 metre (m) in height, 0.5 metres (m) as the width, and a 0.5 centimetre (cm) thickness (depth) where the exterior temperature is 25à °C and the interior temperature is 30à °C. Thermal resistance: R= L/Ak R= (0.005 m)/(1 m Ãâ"0.5 m Ãâ"237 W/m K) R= 4.2194Ãâ"ãâ¬â"10ãâ¬â"^(-5) k/W Rate of heat loss: G=Ak/L(T1-T2) G=((T1-T2))/R G=((30-25)à °C )/(4.2194 Ãâ"ãâ¬â"10ãâ¬â"^(-10 ) k/W) G=(5à °C)/(4.2194 Ãâ"ãâ¬â"10ãâ¬â"^(-10 ) k/W) G=118,500 W This graph shows the change is temperature as a result of heat transfer over time. One temperature starts off much warmer than the other. As the process of heat transfer commences, the hot temperature loses heat and gets cooler. At the same time, the cold temperature gains the lost heat and becomes warmer. When both have reached a thermal equilibrium, there is no more heat to transfer and both remain the same temperature. Heat transfer that takes place in a room is similar to the examples I have given, except that it occurs in three dimensional spaces. This means that other factors are required to make the equations work and come up with an appropriate answer. From these equations, other ones can be created to solve many other problems on heat transfer. Anywhere that temperature exists, there is some sort of heat transfer happening. By predicting, analysing, and testing any equation in thermodynamics, we can learn how to conserve heat and energy for when we actually do need it. Bibliography Kreith, Frank, and Mark S. Bohn.
