The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

There are more and more elderly people and different diseases will affect them. How will the public care be able to face this need of care for the elderly? There are a lot that shows that there will be an increasing demand on the achievements of the relatives. How can this development be answered to? Shall the achievements be concentrated on giving support to the relatives, or will there be a concentration on nursing staff? The purpose of the study was to enlighten who elderly people will be nursed by if a disease affects them.

This essay will explain the effects of decentralisation, and what impact it has on the efficiency to create a better integration for immigrants on the Swedish labour market. Examples of literature that has been examined are Marcus Gossas and Jon Pierre. From these authors, I have been trying to explain the relationship between decentralisation, cooperation and efficiency.Since the end of the Second World War until the middle of 1980, Sweden mostly received labour immigrant. Since then, the immigrant pattern has changed to consist of mostly refugees. Changed immigration patterns together with increasing debts for the Swedish government has lead to decentralisation and cooperation between public authorities has therefore become a target to reach better efficiency.

The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.

Background: Ill-health related to unhealthy lifestyle is increasing and despite existing knowledge about healthy lifestyle it is difficult to change behaviour. Counselling in the primary health care is often superficial and without critical elements for behaviour change. Aim: The aim of this paper to elucidate interventions for change of lifestyle with respect diet and physical activity. Method: A literature review was carried out and ten scientific articles were analyzed and compiled in two main categories: design of these interventions and participation in them. Results: Education, decision making, goal setting, feedback, social support and follow-up were identified as critical elements for behaviour change.

Our curiosity was awakened when we became aware that many social workers use "mindfulness" methods in their profession. In this study, we used qualitative methodology in our desire to examine and understand why the mindfulness approach, with its roots in eastern philosophy, is becoming established in society at large and, simultaneously, being used in the social work field. We were interested in when and why social workers choose to use mindfulness with their clients. Our prior research has revolved around development and use of methods in social work, and on the human reaction to stress.We conducted seven semi-structured interviews, which incorporated four comprehensive questions:1. Why has the mindfulness method become established in the social work field and in the culture in general?2.

This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.

For many years, I have tried to understand why students end up in difficulties in mathematics. As a future teacher, it is extremely important to have knowledge of the various factors that leads to difficulties in mathematics. As a teacher it is obvious to meet the students who find mathematics a difficult subject, and, therefore it is necessary to have a broader knowledge of how to respond and support these students. According to Ahlberg, number of students with mathematics difficulties is increasing every year, therefore, it is important to help students and organize a supporting school environment that promotes and encourages learning (Ahlberg 2001, p. 104-105).

This Degree project is a study about the Mortgage Cap, introduced in October of 2010, and its impact on the demand for rented apartments. The mortgage cap was introduced to decrease the households? loan-to-value ratio and thereby increase their economical resistance during times of financial instability.The past ten years Swedish households have continuously increased their average loan-to-value ratio. In an attempt prevent this negative development Finansinspektionen introduced a mortgage cap stating that banks should no longer grant mortgages corresponding to more than 85 percent of the property?s market value.In order to answer the main question two methods were used both a survey and two interviews.

The web is a constantly growing medium that presumably plays an increasing role in public library reference services. In order to provide high quality reference service the librarians need to be able to master this medium. Therefore it is interesting to get an understanding of how librarians actually use the web. The aim of this Master s thesis is to investigate what web search tools are used by public librarians in reference service. Furthermore, the aim is to get an understanding of how the librarians think about those tools and what background factors influence their selection of tools.

Background: With increasing age follows higher risks of conditions and illnesses which can cause a decrease in health and wellbeing. A meaningful social environment can positively impact the physical health of older people. Dogs are increasingly being used for different purposes within health care and animal assisted therapy aims to improve people?s physical, social, emotional and cognitive function.Aim: The purpose of this study was to determine the effects of animal assisted therapy on older people?s health and wellbeing.Methods: A literature review where searches for academic articles in databases PubMed, Cinahl and PsychInfo were performed. The searches resulted in 14 articles which were selected for further review.

A reforming trend is captured showing that countries are shifting from defined benefit pension systems towards defined contribution systems. The reforms have been justified through predictions that the defined benefit systems will not manage to provide good enough pensions to members in the future. The newer defined contribution pension plans often include individual financial accounts where individuals have the possibility to choose how a part of their pension savings should be invested. Sweden was early to introduce such a system, which at the moment provides more than 800 funds to choose from. The aim of this thesis is to capture the market risk associated with these individual investments and does so by using Monte Carlo simulations for six selected pension funds.

ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method:  Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine.  Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.
