Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.

During the last two hundred years many wetlands and streams in Sweden have been lowered to provide land for agriculture and forestry. Some of the coastal wetlands and streams probably served as spawning sites for certain species of fish in the Baltic Sea, but the present situation is not well known. As standardized methods to monitor fish in running waters are carried out during late summer or autumn, there is a need for methods to sample spring-spawning fish in these streams.The aim of this study was to survey the lower kilometer stretch of Hammerstaån in Stockholm, to investigate the extent to which the stream is used by spring-spawning fish. Furthermore, the study aims to evaluate a new type of survey fishing gill net called strömöversiktsnät (SÖN). This was done by comparing the catch of fish by SÖN with that of fyke nets.

The purpose of this study was to examine what students themselves think about using computers in school. The study was conducted in a school in central Sweden.

The interviews were analyzed using thematic analysis.

Dropout among youth players is a problem in Swedish icehockey. Leaders in youth hockey teams work closely with players on an almost everyday basis during season and have a big influence on players and their activities. This study aims to identify possible reasons for dropouts by interviewing coaches and leaders in icehockey clubs. A total of eight coaches and leaders in different ice hockey clubs were interviewed. Results show that the coaches highlight three reasons for early dropout; focus on competition, results and too much training in younger ages..

The main purpose of this Masters thesis is to examine how Braille users needs are satisfied by The Library of Talking Books and Braille TPB. The other issues are: How do some of the library workers at TPB experience that the needs of Braille users are satisfied? Is it possible to make the service better in the future for Braille users and in that case, how? The study is based upon interviews with five persons, who have defective vision and read Braille. I have also interviewed two employees at TPB who have defective vision. To build up a complete background presentation of the subject I have chosen a book about hermeneutic interpretation to understand how historic facts influence the function of the subject today and in the future.

Regeringen vill lägga mer vikt på att stärka möjligheten till kultur och social delaktighet. De belyser vikten av att skapa trygghet och att minska isolering inom grupper som till exempel långtidssjukskrivna och långtidsarbetslösa. Kulturaktiviteter som konst, film, musik och teater har bevisats ha en positiv effekt på hälsan genom bland annat ökad social funktion, ökad livskraft och ökad fysisk hälsa. Det avser både att delta i samt att uppleva utan att delta i kulturen.Syftet med denna studie var att undersöka om kulturaktiviteter kan påvisa en skillnad i återgång till arbete och psykisk ohälsa hos långtidssjukskrivna personer med psykisk ohälsa, samt undersöka vilken påverkan egna förväntningar har på återgång till arbete. Det insamlade materialet kom från enkätdata ur projektet Kultur och hälsa, genomförd av landstingets enhet Kompetenscentrum för hälsa i Västerås stad.

This makes the study aim regards investigating which non-verbal signals a real estate agent express.Purpose: This study has a two-parted purpose whereas the first part intends to point out similarities and differences in a realtor?s non-verbal communication.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Artificial sweeteners in beverage and their effecton hunger and energy intakeAuthor: Sofia Andersson and Sofia JakobssonSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 11, 2012BackgroundIn 2010 the total consumption of soft drinks in Sweden was estimated to 69 litres per person and17 % of the domestic production was estimated to consist of soft drinks sweetened with artificialsweeteners. The effects of artificial sweeteners on hunger is not yet fully understood. It isspeculated that they might increase hunger and hence increase energy intake.ObjectiveThe aim was to compile the evidence regarding the effects of an intake of a beverage sweetenedwith artificial sweeteners compared to sucrose on subsequent hunger and energy intake.Search strategyA systematic search for literature was performed in the databases PubMed and Scopus.Selection criteriaThe inclusion criteria were RCT, human studies, articles published in Swedish or English, studieson healthy adults and studies measuring hunger with a subjective scale or energy intake. Theexclusion criteria were studies who measured energy intake under other forms than standardisedor controlled, studies without a standardised dose of the beverage and articles needed to beordered against payment.Data collection and analysisFour articles were selected and examined according to a template developed by SBU. Theevidence for each outcome was weighed together and graded according to GRADE based on asummarised evidence form developed by the Sahlgrenska Academy.Main resultsAll four articles measured subjectively rated hunger.

Bakgrund: Bonussystem är något som började växa fram under 1980-talet och är ett inte sällan förekommande debattämne. Inte minst i dagens situation med en stark recession och en finansiell kris om knuten. Flertalet artiklar har tagit upp ämnet, där man har ifrågasatt olika företags utdelning utav enorma rörliga ersättningar trots den svåra tid vi nu befinner oss i. Företagen motiverar olika andledningar till varför de väljer att betala ut bonusar till sina vd:ar, som grundar sig på olika typer av variabler.Syfte: Uppsatsens syfte är att undersöka vilken typ av variabler som visar starkast korrelation med storleken på företagsledarnas bonusar, och att se om dessa kan tänkas påverka deras risktagande.Metod: Uppsatsen bygger på en kvantitativ undersökning av sekundärdata som har inhämtats från de utvalda företagens årsredovisningar. Undersökningen tar en deduktiv ansats, där de valda teorierna appliceras på de resultat som undersökningen visar.Resultat: De fem företagen som betalar ut högst total ersättning är ABB, Ericsson, AstraZeneca, Getinge och Scania.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

The Swedish road transport sector relies almost completely on fossil fuels. In 2007, as much as 96 percent of the total sales of fuels was made up of petrol and diesel, while at the same time the share of total emissions of greenhouse gases in Sweden that came from road transports amounted to close to 30 per cent. Sweden is by no means worse off than any other European country in these respects. In order to address the questions of high oil dependence and CO2 emissions the European Commission has proposed a reinforcement of the legislative framework, with a 10 percent minimum for the market share of biofuels in 2020. Furthermore, the proposed target is binding for the member states, unlike the current voluntary target of 5.75 percent by 2010. More than doubling the usage of biofuels in only a bit more than a decade will most likely not be possible without policy interventions.

Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.

The aim of this essay was to describe and interpret the managements and organizations impact regarding the caregivers working conditions. To examine this we used a qualitative method. We completed two group interviews and five individual interviews with a total of fifteen enrolled nurses that worked within elderly care. In our interviews we found that the enrolled nurses felt that the organizations economic interests collided with their personal values regarding good quality elderly care. We also found that the caregivers experienced that they had an impact on their working conditions and that their employer was the main reason for making it possible..

The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand.
