Föreningslivets (TUF) och skolans betydelse för turkiska ungdomars identitet : En kvalitativ studie om fem turkiska ungdomars uppfattning om deras identitetskapande  

The Swedish society has gone through a radical change. From being a monoculture society it has developed into a multicultural society representing a mixture of people from all around the world. This change has had a significant impact on both the Swedish school system and the teacher?s role. Therefore a subsequent ambition for a multicultural school would be to recognize this diversity and establish guidelines for how to meet each individual students need.

Energieffektivisering i ett verkstadsföretag : En analys av energibesparande åtgärder samt uppvärmnings- och kylsystems driftkostnader och koldioxidutsläpp

The energy use in a workshop company has been examined in this work in order to find areas for energy efficiency improvement. The combined oil and electricity heating in the company were compared with other alternative heating systems including cooling of the premises in following combinations:Ground source heat pump for heating and coolingDistrict heating and absorption coolingDistrict heating and low temperate surface water coolingEnergy use, operation costs and carbon dioxide emissions were calculated for the current heating systems and the three alternatives including cooling. The ground source heat pump for heating and cooling decreases bought energy with 34 MWh annually compared to current heating only. The district heating and low temperate surface water cooling has the largest reduction of operation cost and carbon dioxide. The operation cost decreases with 42 kSEK and the carbon dioxide with 43 metric ton CO2 annually.

Beräkning av koldioxidutsläppet från bostadssektorn i Stockholms län

During the last decades the housing sector has increased continuously, and housings and services accounted for 40 % of the energy usage in Sweden during 2011. The expansion in number of buildings in society has resulted in an increase in both energy usage and emissions of greenhouse gases. It is crucial to enable a sustainable development of society and as a result, the demand to reduce the emissions of carbon dioxide is a current question. In this study, the carbon dioxide emitted from the housing sector in Stockholm is estimated. The housing sector can be divided into different types of houses such as apartment blocks, single-family houses and holiday houses. By collecting information of the energy purchased in respective households, a computational model is generated that calculates the total emission of carbon dioxide.

Hur ser de kemiska principerna för mätning av metabolism med hjälp av indirekt kalorimetri ut? En metodjämförelse mellan Douglas-bag och Oxycon Stationary Pro

Oxygen consumption and carbon dioxide production are usual measurements within the sports and training physiology. The same measurements are also common when it comes to establish the amount of energy that is used during work and to establish the intensity of work. The volume of oxygen that is consumed contra the volume of carbon dioxide that is produced can be used to calculate the metabolic rate within the human body. This calculation shows the percent relationship between carbohydrates and fat in the metabolism. The first accurate method to measure the breathing gases for use in metabolic calculation was established in the early twenty century when the Douglas bag method was introduced.

?Vi läkare är inte utbytbara!?: - en studie om identitetsskapandevid fusioner i sjukvården

During the last 20 years, the Swedish health care system has faced major changes. One of them is the increasing pressure to generate economic profit due to private businesses entering the market. Health care units are forced to make some structural changes in order to become effective and efficient. As a result merger and acquisitions has become a part of the health care sector, and seems to be an increasing phenomenon. Mergers and acquisitions have mainly been studied in the industry.

Aktivering av en dissolvingmassa med enzymer före en konventionell viskosprocess

In conventional viscose manufacturing, a large amount of carbondisulfide is consumed. This amount has to be decreased to keep the production cost down and to reduce the environmental impact. The purpose with this work was to show if an enzyme treatment of a dissolving pulp could increase the degree of substitution in the viscose so that the amount of carbon disulfide consumed in the process could be decreased. Previous investigations by Kvarnlöf (2007), Engström et.al. (2006) and Henriksson et.al.

Vem köper KlimatEl och varför? : Kvantitativ undersökning av Kalmar Energis elhandelskunder

Private individuals can voluntarily buy EU Allowances (EUA) in order to remove them from the European Union Greenhouse Gas Emission Trading System (EU ETS). It leads to progressive reduction of total carbon dioxide emissions in Europe. Kalmar Energi offers customers to obtain one EUA (equivalent to one ton of CO2) per year by paying 25 SEK a month as a KlimatEl-supplement. The purpose of this research is to examine the customers? attitudes in the issue of climate compensation and trying to define the reasons behind their choices.The results of the quantitative questionnaire were analyzed by using descriptive and analytical statistical methods and have shown some correlation between customers? ages and decisions to accept or not the offer of KlimatEl.

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader

Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

Gropkeramiska lerfiguriner ? stumma ber?ttare om en gemensam v?rldsbild

An archaeological excavation that was made in 2016 of a Pitted Ware Culture settlement at Tr?s?ttra in the northern archipelago of Stockholm was very rich in artefacts and features. Especially unique was the over 300 fragments of clay figurines that were found. Never had so many been discovered at a neolithic place in Sweden. In Scandinavia it is only on the Finnish islands of ?land that similar figurines have been found. The aim of this study is to increase the understanding of the clay figurines of Tr?s?ttra and ?land through comparative studies.

Statistisk kartläggning av dimma längs E4:an mellan Helsingborg och Jönköping

Fog is a small-scale weather phenomenon that are fascinating to people. However, the presence of fog in road traffic reduces the visibility and increases the risk of road accidents. By the Swedish Road Weather Information System (VViS), the safety on roads could ameliorate and road accidents caused by fog and other weather hazards could be prevented. Fog is however a complex and usually local phenomenon, why fog formation generally is not easy to predict. For that reason, a statistical mapping of fog, especially along a motorway with high traffic volumes, could be useful in planning to prevent road accidents.

NUDGING Kan nudging leda oss till att äta mer klimatsmart - Ett empiriskt experiment på IKEA med syfte att få restauranggästerna att äta mer vegetariskt

Food consumption generates externalities such as carbon dioxide emissions, which contribute to global warming. The principal issue is that emissions are not covered by the "polluter pays principle". For this reason, new policy instruments need to be tested and implemented to correct the externalities. In food production, beef and dairy production has the largest environmental impact in terms of carbon emissions. As food is a necessity, simply reducing production will not solve the problem.

Title: Overreaction on the Swedish stock market Seminar date:2008-01-30 Course:Nek K01- Bachelor Thesis in Economics (15 ETCS) Authors: Advisor:Oskar Herbe and Ludvig Persson Hossein Asgharian Key Words:Overreaction, Anomalies, Market Efficiency, Contrarian investment strategies Purpose:The purpose of this thesis is to test if the overreaction hypothesis as originally described by De Bondt and Thaler is a good explanation model for the Swedish stock market. Further, our intension is to divide the stock market into three segments by company size, in terms of market capitalization, to control for size effects. Method:We have conducted this study by analyzing Swedish stock data in the period of 1989-2007. Within this time span, using overlapping formation periods, we have constructed two types of portfolios, winner portfolios and looser portfolios. The portfolios represent the 30 per cent best performing respectively worst performing stocks in terms of returns.

Valsningsteknik för extremt höghållfasta tunna stål

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.
