The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

FLUTD - Feline Lower Urinary Tract Disease ? is a complex disease and a common sight in the veterinary setting. Although FLUTD excluding urethral obstruction may be discomforting for the cat and its owner due to symptoms such as periuria, stranguria, hematuria, dysuria and pollakiuria, obstruction presents an acute and potentially lethal form of the disease as a result of uremia and disturbances in fluids, electrolytes and acid-base balances. A study of literature has been performed to investigate the causes of FLUTD with urethral obstruction and the actions available to the owner to avert them. Potential causes of obstructive and non-obstructive FLUTD have been found to include infections, uroliths, urethral plugs, neoplasia, anatomic abnormalities, trauma, neurogenic or iatrogenic causes. Most commonly a cause cannot be identified and the terms idiopathic FLUTD or feline idiopathic cystitis are used. As the mortality rate due to urethral obstruction likely is somewhere around 5.8-8.9% and FLUTD including and excluding urethral obstruction constitute great inconveniences, precautionary measures are warranted.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

The objective of this study was investigating social worker?s perspective of how alcohol consumption can affect, and what elements in the social environment that may be of significance for, alcohol consumption and development of identity. The questions at issue were: Do social workers experience any positive effects from alcohol consumption in 16-17 year-old girls with problematic alcohol consumption and what influence do the effects have on self esteem, self image and development of identity? What do social workers experience are the negative effects from alcohol consumption on self esteem, self image and development of identity? How important do social workers find the social environment and how do they believe the social environment affect the alcohol consumption and development of identity? This was investigated with a qualitative approach from a social worker?s perspective, hence social workers were interviewed. The study?s theoretical basis was Symbolic Interactionism and Erikson?s theory of Psychosocial Development.

Issues regarding the environment are commonly discussed in the media. The most common problem that is discussed is how to decrease the emissions of greenhouse gases by human beings. The municipality of Kristianstad has chosen to work with a project named ?Biogas Kristianstad? which purposes are to use all of the produced biogas as motor fuel and to speed up the introduction of biogas on the local market. This is in an effort to decrease the effects on the environment in the municipality of Kristianstad.

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Abstract The purpose of this study is to examine how teachers in primary school reason about and problematize the phenomenon of concentration difficulties. I want to know what the teachers think characterizes concentration difficulties, the situations in which difficulties creates the most problems, and whether the teachers think that these difficulties solely depend on external factors. To examine this, I chose to do interviews with three teachers in years four to six. I have completed parts of my work with my colleague Elin Preisz. We have used the same purpose and issues in our studies, although Elin has interviewed teachers in preschool. With this we want to be able to compare the reasoning between teachers at different stages in school. The results of my study shows that the interviewees think that it is hard to describe what characterizes the problems in concentration difficulties because the problems is very individual.

The purpose of this Bachelor thesis is to examine how children describe their experiences of their own reading, with focus on different aspects of reading: Choice of reading, reading environment, response to reading and book talk. Our aim is also to examine which approaches to reading their stories illustrate. The research is founded on semi-structured interviews with six children aged 10, in connection with book talks. For analysis we used Åse Hedemark?s study Barn berättar : En studie av 10-årningars syn på läsning och bibliotek as well as Aidan Chambers? theories concerning reading and reading environment.

Aim: To find out what nurses at a hospital in central Sweden are experiencing as good care and what they believe is needed to achieve good care. To examine what barriers exist and how the work environment plays into good nursing care. Method: Descriptive and exploratory qualitative design with semi-structured interviews as the data collection method. Seven nurses, all women between the ages of 25 and 52 were interviewed at a hospital in central Sweden. An interview analysis model was used to analyze the results.

Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.
