This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

A segmented market, according to traditional methods, appears increasingly difficult in mature consumer markets. A common explanation is that the mature markets are often characterised by over-supply which results in a great variety of choices for the consumer. Furthermore, the consumer of today has a more complex and flexible purchase behaviour which is difficult to catch. This makes consumer segmentation difficult. International studies indicate that dividing consumers into generation cohorts might be advantageous in understanding consumers of today.

 The purpose with my study was primarily to illuminate the students' expectations on gained knowledge during their studies at the upper secondary school Hotel- and Restaurant program, and to what extent these expectations were fulfilled. Secondarily, the purpose was to compare the students' expected and perceived knowledge with the program goals set by the Swedish government and the knowledge requirements expressed in a pilot study made by the Education council of the Hotel and restaurant business (UHR, 2007).I chose a quantative approach and I used an anonymous group enquiry among students at the Hotel- and Restaurant program at two different upper secondary schools to carry out my study.Tendencies in the result suggested that the students at the Hotel- and Restaurant program expected high knowledge level within the competence areas of Guest reception and communication, Cleaning and hygiene, Cooking of cold and hot dishes and Waiting. The expectations were not big within the areas Computers and Internet and Business economics and management.Fulfillment of expected knowledge tended to be high within the areas where the expectations were big. It might therefore be a good investment for schools to work on the student expectations to increase motivation within the low expectation areas.A confrontation of the tendencies in the result with the program goals and the competence requirements expressed in the UHR study, suggested that the upper secondary Hotel- and Restaurant education might focus some more the areas of Guest reception and communication, Beverages and Organization of banquets. Business economics and management should be given much more weight..

.Syfte: Syftet med uppsatsen är att undersöka sambandet mellan Morningstars rating och framtida avkastning, samt om detta skiljer sig åt i olika börsklimat.Metod: Undersökningen bygger på en kvantitativ metod då vi har samlat in sekundärdata från dagstidningar och Internet. Den insamlade sekundärdatan kommer att ligga till grund för empirin då vi testar sambanden mellan variablerna rating och avkastning, risk och avkastning samt rating och risk. Teoretiska perspektiv: Uppsatsens teoretiska utgångspunkt är den effektiva marknadshypotesen och kapitalmarknadslinjen. Teorin grundas även på tidigare studier av bland annat Morey (2003). Empiri: Med hjälp av statistikprogrammet SPSS undersöker vi korrelationen mellan variablerna rating och avkastning, risk och avkastning samt rating och risk.

SEB Merchant Banking provides to its institutional customers a true market neutral product called Dynamic Manager Alpha (DMA). The DMA is constructed by a long position in an exceptionally well performing mutual fund and a beta adjusted short position in an appropriate index. The key to making the product market neutral is adjusting with the correct beta, since the beta changes, it is very important to have a good model for predicting beta in the future.This master thesis begins with describing what beta is in a CAPM sense. It then continues with recognizing the so called ?Two Beta Trap?, which separates two kinds of beta.

The aim of this essay is to investigate the attitudes towards religion and religious people held by a group of Swedish high school students. The main questions are; what causes these attitudes andhow do they shape the students? encounter with religion and religious people and in what way could religious education help the students problematize these attitudes?The method used is a quantitative method using a questionnaire, with a Likert scale, posing different questions about religion as such, world religion and religious people. The theoretical basis, in order to discuss the result of the questionnaire, is a gender theory and the theory of social psychology.The result of the study confirms earlier studies of youths both in Sweden and Western Europe. The result shows that there is a certain degree of negative attitudes towards religion, most of all againstIslam.

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity. The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program. The method resulted in four different themes: 1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections. 2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.

During the cultivation season there are a several cropping activities to carry out. At what time these activities are carried out is affecting the result and also on the economy of the crop production. As the production costs are high in potato production, it is important to keep an eye on the economy. Profitability is the most important factor in most crop production systems. If the costs are not covered, it is difficult to justify the production.

Nature´s healing capacity is well known and is today an important asset in the protection against stress. Noise problems in cities and it´s green spaces are increasing which in turn provokes stress and in the long term can lead to cardiovascular diseases. To promote people?s health it is important that natural environments have good soundscapes, research show that visiting natural surroundings and listening to sounds of nature promote rehabilitation and relief stress. The purpose of this essay is to determine the value of rehabilitation in forests in Carlshem and Röbäck.

Background: Atopic eczema has increased in the last decade among children. The nurse can have a major role to prevent the disease. Aim: the aim of this study as to describe the nurses´ work in primary care with prevention to families with atopi with focus on atopic eczema among children. Method: A literature review based on analysis of fifteen scientific articles was done. Results: If the child was breastfed both positive and negative effects were evident.

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Today, the management concept of lean has stretched far from its origins in the Japanese automobile industry. When reaching the Swedish restaurant industry, the conditions for a successful implementation of lean change as a result of the high employee turnover and the significant amount of part-time employees characteristic for the industry. Combined with a high-end service profile, these workforce characteristics seem inconsistent with some of the basic principles of lean. By conducting a case study, this thesis aims to investigate the effects of a variable workforce on the enablers for a successful implementation of lean in a high-end service industry. Using a theoretical framework consisting of enablers for an implementation of lean in services, the study finds that the variable workforce inhibits an implementation of lean by complicating the effects of traditional training, as well as the possibility of understanding the lean concept at all levels of the organization.
