Optimal design av strukturer - Utvärdering av problem och lösningsförslag inom topologioptimering

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Känslor syns inte utanpå men känns inuti : Barns behov av vuxna i sin krisbearbetning

Varje skola har skyldighet att inneha en aktuell krisplan att tillgå vid händelser och situationer som kan utlösa en krisreaktion hos en eller flera individer på skolan. Det finns inga direktiv från varken arbetsmiljöverket eller skolverket kring hur dessa krisplaner skall vara utformade eller vilka händelser och situationer som bör tas upp. Detta ger varje enskild skola stora friheter i utformningen av krisplanerna. Jag har inhämtat krisplaner från fem grundskolor med årskurser från förskoleklass till årskurs fem och gjort kritiska diskursanalyser av dessa varpå jag upptäckt stora skillnader och även likheter mellan dessa vilka jag ger en redogörelse för i mitt resultat. Jag har fokuserat på tre utkristalliserade teman:Elevs dödsfallUppföljning av elever som mår dåligt till följd av inträffat dödsfallSituationer som en enskild skola är ensam om att lyfta uppVidare för jag en diskussion kring krisplanernas utformning och de utkristalliserade teman jag funnit och kopplar dessa till psykologisk forskning kring barns känslor, krisreaktioner samt barnens bearbetningsprocess vid en kris.Jag söker även efter indikationer på att barn som mår dåligt till följd av att föräldrarna separerar lyfts upp i krisplanerna.

Lärarstudenters erfarenheter av förhållandet mellan modersmål, identitet och inlärning

ABSTRACT Our main objective with this essay is to provide a description of old people?s stories about aging. The essay is based on the empirical source of four qualitative interviews with older people over the age of eighty years young. The main goal is to inquire answers about; their time in the workforce; retirements; healthissues; media/advertisements; adolescence/youthfulness and attitudes. The following main questions have been dealt with: What do the elderly emphasize when they describe ageing? Are healthissues the prime subjects the elderly talk about? Do the elderly experience positive or negative attitudes towards ageing? What is their point of view of younger generations? In what way do they describe their years as workers? In what way do they describe aspects about their retirement? We reserved to consider the opinion of their own, to be the most valuable source in our study.

Hållbara uppvärmningsalternativ för hotellstugorna på Grinda : En kvantitativ studie gällande hållbara uppvärmningsalternativ på en skärgårdsö

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

Krigarkvinna i det hedniska Norden : En undersökning av två samtida skildringar av sköldmön Ladgerd i den fornnordiska religionen

The essay has its beginning in the source material that deal with ancient Norse religion before the people in the Nordic countries became Christian. The fact that there are no contemporary written or authentic sources available that can tell us something about the Norse religion during the Viking age is problematic. Archeological source materials is available, but tend to talk more about power relationships and social status than the old Norse religion and the way people practiced their faith. Medieval Christian writers are a source of knowledge of the Norse religion; however, they can only highlight the Norse religion from a Christian point of view and ways of evaluating the pagan faith, making them less reliable.The written sources of this paper are based on the written by two medieval Christian writers, Saxo Grammaticus and Snorri Sturluson. These sources are among the first to treat the Norse religion process after the introduction of Christianity in Scandinavia.

Hantering av negativ eWOM på Twitter - Ett sätt att skapa kundrelationer

Consumers are facing a wide selection of brands trying to get their attention. An increasing amount of corporations are incorporating non-traditional media in their marketing strategies as an attempt to build relationships with their customers. However, along with the new opportunities to enhance consumer emotions about the brand, social media has brought along new risks for corporations to face. This paper investigates the consequences of different ways of handling such electronic word-of-mouth (eWOM) crisis on Twitter. Furthermore, we investigate potential differences depending on the credibility of the source that sent the message.

Hur en för tidig avvänjning påverkar kattens beteende

Enligt svensk lag måste alla katter vara minst 12 veckor vid försäljning. I bl.a. Storbritannien kan kattungar dock säljas vid 8 veckors ålder. Med utgångspunkt från detta har jag ställt upp de två frågeställningarna ?hur påverkas kattens beteende om avvänjningen från modern sker före 12 veckors ålder?, och ?vilka problem kan man som djurägare få med sin katt om den avvänjs för tidigt?. Med begreppet beteendeproblem menas beteenden som anses oacceptabla av djurägaren, som ?wool-sucking? eller överdriven vokalisering.

Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa

Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..

Högskolebibliotekariers informationssökning : en studie i hur högskolebibliotekarier söker information till sig själva och för andra

The purpose of this thesis is to examine how academic librarians seek information for themselves and for others, and what differences exist. The terms self-generated and imposed information seeking is used to describe the two different types of information seeking. Step 2 ? define and understand the problem, step 3 ? choose a search system and step 4 ? formulate a query of Marchionini?s information-seeking model forms the basis of the theoretical framework, which is supplemented with Soergel and Katz. Qualitative interviews with eight academic librarians were conducted and analyzed in order to gather empirical facts.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

Ryssen Kommer : Synen på det ryska hotet i svensk landsortspress, från 1858 - 1898.

With this essay, I want to examine the image of Russians in the Swedish rural press during the second half of the 19th century, how rusophobia appeared in Swedish rural press and how the image of Russians changed during this time. To find this out, I set these questions:  ? How was Russians and Russia portrayed in the Swedish rural press? ? Did the view of Russians change during this time?The essay is written so that I have interpreted my empirical material to do a discourse analysis in which I analyse different articles that have been written about Russia and Russians in a stereotypical way. The source material used in the thesis comes from 41 news articles; the bulk of the source material comes from newspapers that were published during the late 19th century.Rural press reporting on Russia and Russians were in the second half of the 19th century mostly negative. Of the 41 articles that were examined it was found that about half were negative, less than one-sixth were positive, while about a third were neutral.The reason that many of the articles were negative has to do with Sweden's shared history with Russia, with many wars and territorial losses.

Intranät : en kunskapskälla i arbetet?

The ambition with this study is to look into and create an understanding for how an intranet can work as a support system in work processes in capacity as a source of knowledge. We want to enhance the understanding for which kind of knowledge that can be coded in and transmitted by an intranet, and which that is lost in this process. We also want to clarify what it takes to get this knowledge, in collaboration with the intranet, to support the work in an organization. It is a qualitative case study at a Swedish bank. It consisted of semi standardized, half structured interviews with five people in one of the bank?s local offices.
