When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

Background:Incoming medical alarm is a common routine for emergency nurses. Working in these situations may represent a major burden on the individual nurse. Purpose: To investigate emergency room nurses' experiences in receiving medical alerts focused on education, safety, security, skills and experience, and andherence to guidelines. The purpose was also to investigate whether there were any differences in action between the emergency room nurses who had worked longer or shorter period than two years with this.Method:The design was quantitative, comparative and descriptive. Surveys were distributed to 30 nurses who worked in the emergency room at a Swedish hospital.

This essay is about integration's discourses in newspapers. It compares four different newspapers with each other and it compares them also in a time perspective. The four different newspapers that the essay compares are Aftonbladet, Svenska Dagbladet, Dagens Nyheter and Expressen. These are Swedish newspapers and they are distributed all over the country. The time perspective is a two months period, one month in the year 1994 and one month in the year 2002.

Laws and regulations govern the school kitchens in Sweden. The municipality controls how well the school kitchens obey those laws. An annual fee covers the municipality?s expenses for the public control of the school kitchens. To be able to calculate this annual fee, a risk evaluation needs to be done.

SUMMARYEnvironmental issues are currently a hot topic of debate. Studies within the optics branch have not specifically been conducted previously, so the aim of this study was to determine the extent of environmental-awareness specifically within this branch.A survey, consisting of questions relating to environmental issues, was distributed to 100 randomly-selected opticians in Sweden. Of these 100 surveys, 64 were returned and showed a varied branch-engagement for environmental issues.Results of this survey showed that opticians were best in sorting newspapers, magazines, other paper and hazardous waste. Metal and rigid plastic were not sorted to any larger extent.Choosing environmentally-safe products was not so popular and only six stores always do this. 25 shops turn off electrical machines and equipment over night; while the majority of the remaining stores leave the machines on during the night.27 stores did not know if their electrical company provided ?green electricity?.Results showed that there is a lot of work to be done in making the stores more environmentally friendly.

Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.

The purpose of this study is to investigate how power is distributed in the mathematics classroom and how students achieve agency when ICT (Information and communication technology) is used as a teaching tool. Three learning situations, structured by mathematics, are analysed: in the first situation mathematics is taught in a traditional way, in the second mathematics is taught in interdisciplinary projects, and in the third mathematics is taught using ICT as a pedagogical tool. The theoretical concepts of power and agency are used as analytical tools within a socio-political framework. The concept of power is used to assess the students? ability to influence their learning and degree of inclusion in the three learning situations.

This Bachelor Thesis is entitled ?Swedish parental leave and gender equality. Effects on women?s conditions on the labour market?. Through our empirical results in conjunction with economical and sociological theories, this Bachelor Thesis attempts to answer the questions: 1) Why are the claims for Swedish parental leave unevenly distributed between men and women? 2) Does the uneven distribution result in discrimination of women on the labour market? 3) How do different designs of parental leave scheme influence women?s conditions on the labour market and which possibilities are there to change these conditions through changes in the design? We make use of case studies from Denmark, Iceland and Great Britain, which work as basis for policy implications for the Swedish parental leave scheme.

AimThe aim of this study was to try to understand youngsters and their attitude to alcohol in the countryside and in a large city. The questions at issue have been: How do youngsters from the countryside, who drink, and do not drink alcohol, view the school- family- and friendsituation? How do youngsters from a large city, who drink, and do not drink alcohol, view the school- family- and friendsituation? Can we understand youths? attitude to alcohol on basis of the factors: School, family and friends? Are there any differences and similarities?MethodInterviews have been implemented with four youngsters in a large city and in the countryside. To gain as much as possible from the interviews a questionnaire was distributed to two classes in year nine in the countryside, and one class in the large city. The interview material was analysed on the basis from earlier research and two theoretical models.ResultsAccording to the youngsters that drink, both in the countryside and the large city, the most common view in school was that high demands are put on the youngsters and that they should study more then they do.

Cheetahs in the wild are declining due to hunting, lack of prey, exploitation of habitats and loss of cubs to predators. Those are the main reasons to why cheetahs are kept in captivity today for conservation. Many cheetahs kept in captivity are seen pacing ? a behaviour that arise when the animal is prohibited from performing natural behaviours. It is believed to being attributed to a lack of stimulation in the environment where they are being held.
