Shopping for groceries often means that, as consumers, we travel to the grocery store ourselves, by ear, bike or on foot. At the store we pick out the groceries that we want, go the register and pay for them. During the last couple of years consumers in Sweden have been given the opportunity to let someone else select and transport the groceries to their home instead, so called home shopping. As this report is being written, the possibility to buy groceries this way is somewhat limited, but many forecasters believe that in the near future it will increase immensely. Because of the large volumes of groceries that are being transported, there is great transport work being done in the supply chain.
Passivhusen på Oxtorget
Syftet med vårt examensarbete är att undersöka hur passivhus eller så kallade nollenergihus skiljer sig i funktion samt uppbyggnad från konventionella hus.I vår undersökning tar vi upp hur utformning, orientering, material samt ett väl fungerande klimatskal påverkar energiförbrukningen.Vi har tittat närmare på faktorer som sparar energi samt hur ett typiskt passivhus är uppbyggt. För att se hur teorin fungerar i praktiken har vi tittat närmare på befintliga passivhus, nämligen de på Oxtorget i Värnamo.Vi har kommit fram till att passivhus fungerar och vi anser det som väldigt viktigt att man fortsätter driva fram arbetet och informera om dess betydelse för miljön.Passivhus blir mer och mer uppmärksammat. De är något dyrare att bygga, men man tjänar in det i längden. Lönsamheten är dock inte det viktigaste utan känslan av att man gör något bra för miljön..
ESDP - att vara eller inte vara -Rationella förklaringar och ledarskapets betydelse för ESDP:s födelse i Köln 1999.
At the EU summit in Cologne in 1999, a consensus was reached concerning the common foreign and security policy within the European Union. It was decided at the summit that the WEU (Western European Union) should be incorporated into the EU - whom would then be given military capability to act autonomously without the necessity of Nato involvement. This essay investigates the factors that made this agreement possible from a rational choice perspective, but also from the perspective of the power and influence on negotiations on behalf of various types of leadership present at the meeting. Many nations at the summit of Cologne where for the creation of a military force in the form of ESDP (European Security and Defence Policy) within the Union, and many where against such a decision. However a consensus was reached and that is what this essay shall try to explain.
Går Sverige mot en mer hållbar energianvändning?
Sambandet mellan samhällsutvecklingen och de växande miljöproblemen kom i
slutet av 1980-talet att få en allt mer framskjuten roll på den politiska
agendan i Sverige. I och med att energianvändningen står för en stor del av
miljöproblemen har allt fler kommit att inse vikten av att uppnå en hållbar
situation för energianvändandet. För att se hur arbetet mot en hållbar
energianvändning fortskrider har International Atomic Energy Agency (IAEA)
tagit fram en modell för detta. Studiens övergripande syfte har varit att
analysera huruvida Sverige går mot en mer hållbar energianvändning med
hjälp av IAEA:s indikatorer. Teorin i studien har baserats på grundläggande
miljöekonomiska resonemang.
Analys och beräkning av emissionsfaktorer för växthusgaser
An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
Eskortverksamhet med fokus på försäljning av BDSM-tjänster
The purpose of this study is to examine escort-business with a focus on sales of BDSM-services (Bondage and Discipline, Dominance and Submission, Sadism and Masochism).
The study is based on qualitative interviews with three informants providing BDSM-services, as well as a survey with 96 men who requested domination of escorts (the survey was carried out by an escort in the 1980s). The analysis of this material resulted in the identification of three themes on which the study centers: The personal experiences of the three escorts, the interaction between the escorts and the clients, and the changes over time when it comes to the performance of BDSM-services. The study has a gender perspective. The important conclusions are that there are several differences between prostitution having a focus on BDSM-services and other prostitution.
Fodersammansättningens betydelse för tillväxt hos häst :
The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.
Simulering av värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem
In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.
Sekundärnät för lågtempererad fjärrvärme
Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

Hållbar energi : - Ett initiativ till utveckling av bränsleceller i Sverige
In the world we live in today the environmental issues has become increasingly important, and we have begun to realize that we can not continue to use fossil fuels at the rate we do. When it comes to generating electricity we are constantly trying to come up with cleaner and more efficient solutions. The fuel celltechnology is one such alternative and has been around for over 100 years. Yet, it is not until now that the world has started to notice this great technology. The fuel cell has been developed in several areas and can today be used for handheld electronics, vehicles and small settlements.
Undersökning av solcellspotentialen för golfverksamheter i Sverige
Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.
Utveckling och konstruktion av dämpare och låssystem för vågkraftverk
The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.
En beslöjad debatt : En jämförande diskursanalys mellan den mediala och den politiska diskursen av burka i Sverige utifrån Köpenhamnsskolan
The debate concerning face veiling has been brought in to view by several governments in Europe. Luca Mavelli studies the debate regarding the burqa using the concept of securitization and from that the objective of this study is to analyze the medial- and the political discourse in Sweden regarding the burqa. The formulated questions drawn from this is; who are the securitizing actors? According to the securitization actors, who can de defined as a referent object? Wherein is the threat according to the securitizing actors? Is it possible to recognize a difference between the medial and the political discourse?Furthermore the paper adopts the theoretical framework that is the concept of securitization, formulated by the Copenhagen School of security. The methodological foundation is based on a social constructivist approach and consequently uses Norman Faircloughs critical discourse analyzes as an analytical tool.
Improvement in agricultural production in a rural area of Cambodia between 2004 and 2011 - with an emphasis on small scale cattle production
Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.
