The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.

The purpose of this project has been to cut production costs for the fascia panels ofGetinge?s largest autoclaves. The cost for the stainless steel plates currently used is veryhigh. An alternative material solution could cut costs significantly.In addition, improvements have been made to the instrument tower which is a central partof the fascia panel. As a result of the new modular design in a new material theinstrument tower has been improved in several aspects..

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

The aim of this Master?s Thesis is to study readers and authors of Harry Potter fan fiction, in order to answer the question of why they read and write fan fiction about Harry Potter, and which factors determine what kind of fan fiction stories they read. The empirical material consists of three qualitative interviews with fan fiction readers and authors, and a textual analysis of four internet forums for discussions about Harry Potter and fan fiction. The theoretical background is based on reception theory and reader-response criticism. The results show, that commitment to, and interest in, the source material is an important reason as to why the participants of the study read and write Harry Potter fan fiction.

Vattentäthet och ?andning? är två eftersträvade komfortegenskaper hos funktionsplagg idag. Utveckling pågår kontinuerligt och nya material dyker ständigt upp på marknaden. Vattentäthet mäts vanligtvis genom hydrostatisk testmetod där resultatet visar de tryck i meter vattenpelare (mvp) ett material klarar innan 3 droppar tränger igenom dess konstruktion. Prestanda i mvp hos funktionsplagg kan idag sträcka sig till upp emot 30 mvp.

Earlier quantitative entrepreneurial studies with a focus on poverty rate has centred their arguments and analyses entirely on income differences which has resulted in a high poverty rate among self-employed. Their results shows that variables such as age, gender, hours of labour and structure of the household significantly affect the poverty rate among self-employed. In this study we aim the focus on material living standards instead of income differences, thus using a more representative approach while studying entrepreneurial poverty. The purpose of the study was to examine how personality traits (big five) affect the material living standards among the self-employed in Sweden, using a group of employed as a control group. Variables earlier known to affect the poverty risk among self-employed where used as control variables together with education and household income.

SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

Aim: The aim of this study was to examine health professionals´ experiences of giving advice regarding sleep to parents of infants and to perform and evaluate an intervention in the form of introducing information about the sleep of infants.Method: The study was designed as an intervention study with a qualitative approach where data was collected from two focus groups in the form of interviews. The intervention consisted of the information material Sugen på sömn. There were five participants whom three of them participated in the second interview. The interviews were processed by content analysis.Results: Health professionals´ experience of giving advice on sleep was summarized in three themes. The experiences of giving advice in interaction with parents, health professional themselves experienced the power to influence the parents with the advice they gave, while the parents' previous experience and knowledge impacted on how the advice came into practice.

Cremated remains have long been regarded as a highly complex material that often provides unsatisfactory results. This essay discusses the problems that arise when methods commonly used on unburned bone material are used in a cremated skeletal material. The present essay discusses the results from osteological analysis of seven cremations from Pre-Roman Iron Age from a large cemetery in Alvastra, Smörkullen. Several methods were ultimately not applied in the present study as they were insufficient for application on the relevant material. Since the methods were inapplicable and fragments available for gender assessments too low, no sex assessments were made.

Arbetet handlar om hur förskollärare arbetar med antalsuppfattning i förskoleklass och vad de utgår ifrån för material i detta arbete då deras läroplan Lgr 11 (Skolverket, 2011) inte har med något om antalsuppfattning. Förskoleklass är övergången mellan förskola och skola från hösten då eleven fyller sex år. Det är en frivillig skolform. Syftet med arbetet var att besvara följande frågeställningar: Hur arbetar lärare i förskoleklass med antalsuppfattning? Vilket material utgår lärarna från i sitt arbete med antalsuppfattning? Vi har använts oss av en kvalitativ undersökning.

This report will outline a proposal for the improvement of the baggage sorting facility at Arlanda airport. Swedavia is a state owned company group that operates, owns and develops airports in Sweden. One of their main roles is to create accessibility needed to facilitate and streamline the work at the airport.Swedavia is constantly working to develop new solutions and enhancements that will help to standardize and automate the work at airports without major impact on climate and above all adapt these solutions to work.The project has been aimed to identify and isolate the problem at the check-in counter, investigate the possibility of setting a speed control on the DC motor driving the luggage conveyer belt at the check-in desk so that the luggage does not lose tracking already there, as well as evaluate the new sorting systems planned to be introduce in the upcoming refurbishment of the sorting area.To determine the parameters that are used to regulate the speed of the baggage conveyor belt, information about the inputs and outputs that participated in the process was gathered. Information was collected both practically and theoretically. Process was followed and monitored by the supervisor of the company, and a theoretical study was done separately on my own.

Resultatet från TIMSS-undersökningen år 2011 visar att svenska elever har försämrat sina kunskaper inom området taluppfattning. Matematikundervisningen är vanligtvis läroboksstyrd med lite variation i arbetssätt. Författare och forskare belyser att laborativt material är ett redskap som kan användas för att konkretisera abstrakt matematik. Därmed undersöker denna studie hur användandet av laborativt material inverkar på elevernas utveckling av taluppfattning. Vidare granskas relevanta faktorer som läraren bör ha i åtanke vid denna undervisningsmetod.

The primary purpose of this paper is to find the determinants of first-day returns on the Stockholm Stock Exchange. Our research will cover the 1996 ? 2004 periods. Our secondary purpose is intended to find a profitable trading strategy with regard to future IPOs on the Stockholm Stock Exchange. By using regression analysis, focusing on company specific factors and the IPO process, we hope to find a function exhibiting statistical significance, determining future first-day returns from which construction of a profitable trading strategy will be possible.
