In this paper I will present my research about different kinds of social workers, and there way of looking at and working with adolescents alcohol use. To get my result, we interviewed eight social workers from four different organizations. The Interview participants were people working with adolescents on their spare time, and in the school environment. There were also participants representing social services and the police. The theory that we have chosen to apply to our thesis is systems theory.

In this work an assessment of the compressed air system in the facilities of Vattenfall Heat Uppsala has been conducted. The facilities constitutes, among others, a combined heat and power plant, and two waste incineration plants. The compressed air is supplied primarily by seven rotary screw compressors and yearly electric energy consumption in these has been determined. Furthermore, the usage of compressed air has been mapped in order to find processes with energy savings potential. Several suggestions how to reduce the usage of compressed air have been presented, resulting in decreased need of electric energy and reduced CO2-emissions.The results show that total need of electric energy in the compressors, during a standard production year, amounts to 5.83 GWh.

Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare. The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.

Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.

According to the immigration service forecasts Sweden faces large refugee influxes in the coming years. This means that educators in the kindergarten, preschool and school, will meat children from the war torn countries. In this study, the purpose is to find out the educators different conceptions of war-affected refugee children, because my theory is that their beliefs influence their actions. I wanted to get answers to their beliefs about the difficulties or challengers that children and educators may be faced with. Furthermore, I wanted to know what educators envisioned about their own role?s importance to the war affected refugee children and their perceptions of the Swedish culture, environment, language and school.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

The purpose of this thesis is to examine how reading different media forms can lead to different experiences for the reader and how they choose which media form to read. Two questions are posed in the study. Question number one is: How does the media form influence the reading experience of the book and question number two is: What reasons can be seen behind the different choices of media forms?The study is based upon qualitative interviews with six readers using different media forms. Two different theories are used for analyzing the result.

This report consists of two parts, out of which the first deals with the planning and designing ofa small house in the Swedish city of Huddinge, using the weather conditions of the Swedish cityof Malmö. The house has to be in accordance with the Swedish building- and constructionregulations, as well as with the limitations in energy consumption given.The house itself has to consist of at least two bedrooms, and blueprints of the house, variousconstructional elements, ventilation, sanitation and electricity have to be drawn. Calculations ofthese aspects also have to be made, to ascertain that the different parts function as they should,and that the dimensions are sufficient.The second part is called ?Allergy free home?, and investigates how indoor climate affects us,and whether it has changed during the last few decades. It also makes an effort to see whetherthe increase of allergies and asthma is correlated with possible changes in indoor climate, andwhether technical solutions might help to handle or even decrease the issues arisen.

Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.

Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Animal welfare during transport has for a long time been a problem around the world. Many animals are transported in stressful environments for slaughter. Even during Roman and Antiquity times wild animals were transported from Africa to the amusement parks in Rome. The aim of our work was to compare how well Sweden and Denmark are performing their inspections of transports of cattle and pigs for slaughter. Today, overloaded transports and poor treatment is not uncommon in Europe and every year 22 million animals are transported between countries.

The purpose of this essay is to analyze and understand how people in different ways can take on the role as carriers of brands and understand what part they play in today?s society. Brands are everywhere today and the competitions are becoming harder and harder for the customers? attention and consumption, which is why I am curious of how an individual in a company?s frontline or a celebrity can help the success of a brand. The essay is based on a qualitative method where six interviews have been performed.

Abstract The global average temperature has increased by 0,74°C over the last 100 years. Most probably, the explanation is due to increasing use of fossil fuels and the agricultural expansion of land use. The new life stile of mankind leads to increasing concentrations of greenhouse gases in the atmosphere. Food consumption contributes with approximately a quarter of the total greenhouse gas emission per person and year, why it is an important task to reduce these. The aim of this work is to quantify energy use and greenhouse gas emissions for (Swedish) herbs produced in Swedish greenhouses. The study is based on a LCA (Life Cycle Assessment) and collected data from participating companies producing herbs in pots.
