Cryogenics And The Future :: essays research papers

Cryogenics and the Future Cryogenics is a study that is of great importance to the human race and has been a major project for engineers for the last 100 years. Cryogenics, which is derived from the Greek word kryos meaning "Icy Cold," is the study of matter at low temperatures. However low is not even the right word for the temperatures involved in cryogenics, seeing as the highest temperature dealt with in cryogenics is 100 (C (-148 (F) and the lowest temperature used, is the unattainable temperature -273.15 (C (-459.67 (F). Also, when speaking of cryogenics, the terms Celsius and Fahrenheit are rarely used. Instead scientists use a different measurement called the Kelvin (K). The Kelvin scale for Cryogenics goes from 173 K to a fraction of a Kelvin above absolute zero. There are also two main sciences used in cryogenics, and they are Superconductivity and Superfluidity. Cryogenics first came about in 1877, when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure"(McClintock 4). After Cailletet and Pictet, a third method, known as cascading, was developed by Karol S. Olszewski and Zygmut von Wroblewski in Poland. At this point in history Oxygen was now able to be liquefied at 90 K, then soon after liquid Nitrogen was obtained at 77 K, and because of these advancements scientist all over the world began competing in a race to lower the temperature of matter to Absolute Zero (0 K) [Vance, 1-10]. Then in 1898, James DeWar mad a major advance when he succeeded in liquifying hydrogen at 20 K. The reason this advance was so spectacular was that at 20 K hydrogen is also boiling, and this presented a very difficult handling and storage problem. DeWar solved this problem by inventing a double- walled storage container known as the DeWar flask, which could contain and hold the liquid hydrogen for a few days. However, at this time scientists realized that if they were going to make any more advances they would have to have better holding containers. So, scientists came up with insulation techniques that we still use today.

Mango Street Essay Essay

Throughout history, women have been seen as inferior to men. In the novel, The House On Mango Street, the main character, Esperanza sees many examples of women who are treated lower by their husbands. These women are imprisoned in their own homes on Mango Street. The author, Sandra Cisneros uses the motif of Imprisoned Females to show that women have been seen as inferior to men. There were many chapters in the novel in which women were seen as inferior to men. On page 79 in the novel, Rafael gets locked indoors because her husband is afraid Rafaela will run away since she is too beautiful to look at. Rafael is just one of the many victims of Imprisoned Females on Mango Street. She is scared to leave because she thinks her husband will do something, he doesn’t want other man to take her away from him. Esperazana could also been considered a â€Å"Imprisoned Female. All she wants to do is live in a house she can call her own and be free but she is stuck on Mango Street where she meets all these other women who are stuck like her and she thinks she will never get out. Men treat women like they are nothing. Why? Because they are scared. Scared that women will leave them for someone better. Scared that women will tell someone of all the awful things they have done to them. Scared that women will finally tell the truth.

RoseWood Hotels & Resorts

RoseWood Hotels & Resorts: Branding to increase customer profitability and lifetime value. Rosewood Hotels& Resorts(Rosewood) , a private hotel management company started in 1979, that built a global reputation with iconic luxury hotels such as The Mansion and The Carlyle, became well known for its ability to enhance a property’s value by creating unique, one-of-a-kind properties with a small ultra-luxury residential style. But amidst this, the brand ROSEWOOD became muted, unmentioned. The issue here is to establish Rosewood as a true brand. A branding decision is to be made to establish the company’s future. Rosewood with or without a corporate brand needs to be evaluated in order to arrive at a decision. The first thing is-whether or not a corporate branding. * Establishing a corporate brand would mean to fall into the same league where other corporate brands were in. Rosewood without a corporate branding was at par with the branded ones. Its occupancy rate across years has been almost the same for- be it The Marriott or The Four Seasons Hotels, inspite of relatively higher prices at RoseWood. Moreover, it would mean to keep the brand promise across the properties – by ensuring perfect product/service performance across the portfolio, internal soft branding initiatives and significant marketing investment. But keeping in mind the uniqueness of each Rosewood hotel and their â€Å"SENSE OF PLACE† philosophy, consistent brand-wide performance standards seems a bit unrealistic. Each place has something new and unique to offer its guests. Standardizing it was not the Rosewood way of work. They understood the customer needs according to their functioning place and believed in offering the same. This was their Unique Selling Point and diverting from this would mean a high impact on the customer expectation. A corporate branding is not the only solution to increasing the customer profitability and lifetime value. Surely Rosewood needs cross-property increase. Seeing RoseWood’s statistics, upto 40% customers come back to the same hotel of Rosewood’s But only 5% are involved in cross property usage. In the individual brand range, they typically had 5-10% cross property usage rate and this number went upto 10-15% In case of corporate-branded hotels. But RoseWood was struggling at a mere rate of 5%- the lowermost rate even in the individual brand range. So they need to boost up this number to at least gain the higher edge in their own category of individual brands. I would suggest these short term course of action so as to achieve higher customer profitability and lifetime value. 1. People definitely like being at RoseWood- keeping in mind their occupancy rate (average of 60% for last 3 years) and 40% customers coming back again to the same hotel. Customers are happy to be at RoseWood properties. But little can they relate with other RoseWood hotels. The RoseWood hotel they go to provides them with a comfortable stay. When their guests go to a new place that also has a RoseWood property, they should know what to expect and those who liked it first will definitely want to have the same comfortable stay again. For e. g. A Mc-Donalds store worldwide is known for the food they provide. When going in a Mc-D they know what to expect and what level of food they will get. But even a Mc-D store in Gujarat has customized itself according to the place they are at and provides only vegetarian there. RoseWood’s main strength is their uniqueness. But they need to build an inter relation among their hotels so that they maintain almost same level of service and comfort. People should go in to experience something new but with the faith of same level of service. 2. When a customer checks-out from a RoseWood property, they can be asked to fill a small interactive feedback form and a satisfied customer should be handed with a handout of other RoseWood hotels with a promise that they can have the same satisfaction of stay there as well. . RoseWood can implement that when a guest leaves, he is made aware of other RoseWood hotels with a provision that whenever they are to go to a place having another of RoseWood’s hotels, they can just contact the manager of their regular RoseWood hotel staff/manager and all arrangements for their stay at that place can be made beforehand as per the guests convenience. Also, by this the customers would not go to a new place and make choices whether or not to turn up to RoseWood hotel at that place. They could implement the branding in a bit subtle way like The Mansion-from the house of RoseWood or The Mansion (RoseWood properties) so that people can be aware of and relate to them. 5. They need to collaborate more with the travel agents. They do promote the hotel but not the brand. Educating the customers about RoseWood as well along with the hotel would help the customers to relate and entrust in them. 6. Even the guests who have stayed in RoseWood hotels do not know of RoseWood as a brand. They need to bring the guests’ focus on RoseWood as well during their stay. Logo and promotion should be moved towards higher profile amenities as well. Their conversations on telephone to the dress of the staff should justify that they are a part of the RoseWood. As far as the long term initiative is concerned, being a status symbol never hurts. In Fact it is the need of the hour to be a leader in the competition. So, they might as well like to go for corporate branding if willing to compromise on their â€Å"Sense Of Place† philosophy to some extent.

Tranquility of a Cemetery

As we come in to a cemetery, we might be filled with fears or have some sort of dreadful feeling. Our first impression may be of dark cold nights and ended lives. What is a scary and dreadful place for some people; it is a very meaningful place for me. This place is so meaningful to me because my father is buried there. Cemeteries are important to bringing perspective and serenity, because they bring us a connection to where we came from, it helps us realize the tenderness of life, and they help us to relax a little bit through their calmness. I have had so many things impact my life and they all seem to end up in the same place. Cemeteries are not the dreaded and scary things of superstitions. They are holding places for memories and faith. The memories I hold from Bellevue memorial park are not from within the place itself but from the people it holds. It helped me realize the delicacy of life by taking many people I loved before I expected them to go. My father is buried in my most meaningful place; my grandma and one of my uncles are there too. The day we buried my dad it was a beautiful day outsides, it was nice and sunny although it looked like it was going to rain. As I entered the cemetery I saw tombstones piled up from left to right and right to left , there’s was people buries in every direction. On one corner there are tombstones dated as far back as the 1800’s, those are the oldest tombs. Then there’s a section as you are coming in to the cemetery, called the mausoleum. As you go in there it’s very quiet, but the smell of the mausoleum is the same smell of a rotting piece of meat. As you approach to the middle section of the cemetery there is the baby section. This section is always filled with balloons flowers and all kinds of decorations, for their birthdays or special occasions. This is the saddest section of the whole cemetery because you always see at least 1 mother crying to their dead child. In the older sections of the cemetery there where caskets coming out the ground, you could see that since they have been there too long the dirt has pushed them out. I walked around the whole cemetery and I felt sad for all f these people that have lost their lives in accidents, crimes, or just health problems. I kind of felt like I was in fear of losing my life too, because I was surrounded by death. As we approached to the section where my father was going to be buried, it smelled like fresh flowers and plants, but if u smelled deep enough there was a humid smell in the air of the rotting corpses underneath the ground I was stepping on. I’ve been at this ce metery three times and as close as I can remember it felt the same. I felt scared, anxious; my heart beat was accelerating as we were getting closer to putting my loved ones underground. The grass was green and freshly cut; it seemed as if they had just cut it for this occasion. Every time I go to the cemetery I’m not scared anymore I feel peaceful, when you go there you get relaxed because it’s very quiet, there is no sound in sight all u can hear is the static in your ears. Also it’s hard to explain the emotions you get as you enter a cemetery; you feel sad, scared, anxious lots of mixed emotions. One thing I remember the most is the feeling of knowing that once my dad was going underground I was never going to see him again all I was left with was his memory and his tomb.

Development within the European Union of the Second World Countries Assignment

Development within the European Union of the Second World Countries - Assignment Example Thus, in the course of discussion on the development process of these countries, it is inevitable to tackle the history of transition of these countries from a system of planned economy to their membership to the European Union and their subsequent integration to the global free market. A brief presentation on the situation of the Second World countries during the late 1990s was presented in this paper; however, the whole discussion gives its main focus in the past ten years of the new millennium. Introduction The European Union has become one of the most influential economic and political organizations in the world since the Second World War. Starting from a membership of six countries in 1958, European Union has now a membership of twenty seven countries and still expanding. European Union was established based on the framework of Europe-wide single market that would promote peace, stability and prosperity. Economic cooperation is at the core of the guiding principles of EU country -members basis of unity. EU stands for borderless economy within Europe and strives to make Europe an accessible place to live and work for all the Europeans. It is still a glaring reality; however, that unequal development still exists within the European Union. For the last five to ten years, changes within the boundaries associated with the European regions have caused altered changes in the economy of European Union. Despite of the thrust to create a single Europe, member-countries of the European Union sill differs from each in other in terms of economy, politics and social well-being of the people in the society. Specifically in terms of economy, the differences between the second world countries within the union have created a gap in the past decade. The economic activities of the second world countries in the region have been directly affected by their membership in the European Union either positively or negatively. How do the second world countries progress as members of t he European Union? Is this helpful for them as a whole? Basically, this paper will delve on these matters. This paper will examine the economic growth of the second world countries within the European Union for the last five to ten years. This paper also tries to establish that in as much as the Second World countries need the integration within the framework of the European Union, Europe would also benefit from the accession. In the past years, Europe has been insulated in productivity, especially in terms of labor. An American worker generates 27 percent more output per dollar compared to the European workers. Employers in France and Belgium are entitled at least twenty six paid national holidays in addition to their vacations. A German worker being is paid with 14.5 months of work per year but actually works for 9.5 months (Tupy, 2003). Also, the European GDP per capita today is less that two thirds compared to that of the United States, whereas they were roughly equal before. Th e glaring reality of Europe’s economy – slow growth, generous social provisions, high unemployment rate, and high taxes on European’s citizens – raises questions on the correctness of the European economic model would be able to help the Second World countries in their thrust for prosperity (Tupy, 2003). Thus, this paper will also discuss how the status of the economy of the second world countries affects the stature of European Union as a whole. Second

Audit of School Community Resources and Supports Assignment

Audit of School Community Resources and Supports - Assignment Example This makes the school administration to document the resources that it has and identify the gaps and weaknesses. Using this information, it can devise viable ways through which it can source for important resources. It is against this background that this paper provides an audit of the school in light of the community services and supports. To ensure a coherent consideration, it analyses the relative strengths and gaps in a bid to underscore the extent of these inconsistencies to the performance of the school and improvement of student behavior. Activities Conducted During the Audit The researcher spoke to about 50 individuals to determine the type of resources and support systems that were in place as well as their importance to the school. This also sought to determine the resources that were missing and what would be done to ensure that they are sourced. Further, the researcher interviewed the students to determine the manner in which they benefit from the available resources. The interviews were aimed at establishing whether the students are comfortable with the available resources and what they think should be done to improve performance. The researcher then spoke with the key stakeholders in the industry and specifically, those that were directly involved in the support system. These ranged from the school administrators such as the superintendants, teachers, chief academic officers, parents and a host of other education officials. Further, the researcher conducted a survey of the fifth grade students to determine whether they feel both physically and emotionally supported, safe, challenged or connected. Underlying efforts in this regard were also geared towards underscoring the nature of the learning environment and to what extent it encourages, inhibits or and supports social responsibility. Finally, the researcher reviewed the reports that had been previously made regarding the current support systems, their impacts on the behavioral wellbeing of the s tudents as well as their contribution to the academic performance of the students. The preceding activities had insightful views about the state of the support system and its contribution and influence on the overall performance of the students. They identified the support systems and services currently available and those that are missing. Most importantly, the findings underscored the strengths and weaknesses of each. At this point, it is worth noting that the preceding information is vitally important. Essentially, Scott and Hunter (2001) assert that it would act as a basement upon which critical decisions would be made. In particular, it would be important to positively emphasize the strength and eliminate or discourage the weaknesses. This way, the support systems and services would yield desirable outcomes. Critique of Strengths and Gaps One of the strengths that the institution has pertains to the active parent involvement in the education of the students. In this regard, the parents are well informed about their roles in the learning process. They attend all the meetings that are geared towards addressing the challenges that the students face. In addition, there is a cordial relationship between the teachers and the parents. In this respect, Lawson and Sailor (2000) assert that active involvement of the parent in the life of the student enables the former to understand the challenges being faced by the
