Today?s environmental discussions have led to more progress in the different transportareas. To ride a bicycle is often one of the most efficient alternative when it comes totransport. An Electric bike is, and makes transportation more efficient than a regularbicycle. Electric bicycles do not affect the environment significantly and allows moreconvenient transportation than ordinary bicycles do.

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Background: Myocardial infarction is the most common individual disease among people in the west world. In Sweden there are over 50 000 women and men who get myocardial infarction every year and about 40 % of them dies. Exercise training is one part of cardiac rehabilitation and since 1980 Sweden use the guidelines from that time. Aim: The aim was to review exercise-training modalities in cardiac rehabilitation after myocardial infarction and the physiologic- and psychological effects. Method: Facts were obtained by searching through the database PubMed for articles published from 1994 and ten years forward.

Abstract Title:                       Grades at Primary School ? A study of local politicians' arguments in                       connection with the division into grades at Swedish primary schools.Author:                       Annie LinderUniversity of KalmarC-essay in Social StudiesAutumn 2011 The study aims to investigate local politicians' decisions since municipalities took overSwedish primary education in 1990/91. The arguments put forward in support of how stages are organised have been studied, likewise whether municipalities have acted rationally when making their decisions.Six municipalities are included in the survey. They were divided into three educational categories: lower, middle and high level schools; previous and recent schools and F9 schools with pre-schools and primary schools integrated.Minutes from politicians' and civil servants' meetings have been studied and categorised according to arguments for and against. The most common supportive arguments are about economy and organisation, others concern school premises, trends and the wish for a comprehensive compulsory school.

Our main purpose has been to describe and compare two community's ways of organising and executing the social welfare sectors drug and alcohol abuse programs. We also wanted to explain the similarities and differences we found with the help of an organisations theoretical perspective. A second purpose has been to try to find out if the difference affects the clients possibility to receive equal care.To find out how the community's organise and execute their drug and alcohol programs, we interviewed two social workers in leading positions in Landskrona and Ängelholm. We have further more, to find out if the differences we found influencing the clients possibility to recieve equal care, completed an inquiry with fictional cases that all of the involved social workers, at each community, built an opinion upon.Our main result showed more simmularities than differences in our two community's ways of organasing and executing their drug and alcohol programs. We judged the clients possibility to adequate care to be equally sufficient no matter where he sought care, since our study showed that the social workers choice of approach did not differ significantly between the two communities, even though we found differences in their way to organise and execute the social welfare sectors drug and alcohol abuse programs..

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

In this report the importance of irrigation scheduling in dry climate is shown, how it can save water and energy; how this method can improve crop yield by supplying the right amount of water at the right time. It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..

The aim of this study was to understand the everyday mobility of families who are involuntarily carless and the practical consequences that arise when the private car is not an available alternative. Previous research shows that the involuntarily carless, as opposed to the voluntarily carfree, generally have lower income and fewer mobility options. This, in turn, affects the available strategies for organising everyday life. Using qualitative interviews, guided by thematic analysis, this study explores how carless families organise their daily lives and what strategies they use to make everyday life work.The results show that these carless families use a variety of transport modes, though the degree to which they use different transport options is highly situational, depending upon the length and distance of the trip, along with material and monetary means. Multiple interviewees recount that they lack the financial resources necessary to use carpooling options, to pay for public transport, or to buy bicycles for the family.

The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.

The main purpose of this study was to determine the impact of bedding material on the faecal microflora of horses. Another objective was to investigate the hygienic and physical qualities of the bedding materials used and how these may change in the course of the trial period. The bedding materials used were sphagnum peat and wood shavings. Six horses had each material as bedding for a three week period in a change?over experiment.

Background: In the past 10 years private label has increased significantly in the Swedish grocery market. This is an important strategic event, which is a great challenge to suppliers as it causes stiff competition. To handle this situation an increasing number of suppliers have to make the decision whether to produce private label or not.Purpose: The purpose of this study is to find and analyse factors that influence suppliers in the Swedish grocery market to produce private label. On this basis we intend to confirm or develop existing theories within the field of study.Research method: The study has a qualitative approach where empirical data has been gathered through interviews with suppliers and retailers in the Swedish grocery market.Results: This study has identified factors that underlie suppliers? decision to produce private label.

The purpose with our study is to investigate in which way a public field of action has succeeded to make the economic management more effective and also find out which factors/activities that have contributed to get the result of the budget in balance. We also want to find out in which degree the balanced scorecard (BSC) has contributed to the positive result of the budget. Method: We had started out from the qualitative method theory which is based on the hermeneutic theory, because we will interpret and understand. With this starting point we have chosen to use a case study with semi-standardised interviews supplemented with information from different documents, and to get the theoretic connection we have studied literature in the subject field. The analyse and even the theoretic connection have then started from, for this study, a special analyse model.
