Vinster med återvinning, Stena Recycling
This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.
"Sök Er ej till Stockholm" : -Om sambandet mellan bostadsbrist och tillväxt
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Energieffektiva principer : Påverkan på en villas arkitektur och energiprestanda
Kraven på att nybyggda bostäder ska vara energisnåla i driftskedet ökar hela tiden av flera anledningar. Dels vill brukarna hålla driftskostnaderna så låga som möjligt och dels är det miljöaspekten som spelar in. Men hur energisnål kan en villa egentligen göras och hur påverkas arkitekturen då den görs extremt energieffektiv?I den här rapporten utreds tio energieffektiva principer som kan användas för att göra en villa mer energisnål och energiproducerande. Alla tio principer har tillämpats i en villa som projekterats under arbetets gång.
Det praktiska intellektet: timmerlagning med mallbr?da som exempel
This thesis presents a method of making repairs in log houses. The purpose of the thesis is to use this
method to exemplify crafters practical intellect. The method is based on the use of a template board to
transfer the measurements onto the new log. There is a dearth of literature dealing with timber repairs,
and the literature regarding using a template board for this is non-existent. The description of this
method has therefore been compiled from interviews with active timber crafters.
Underifrånperspektiv - en analys av utvärderingen av demokrati och delaktighetsmålet i storstadssatsningen i Malmö
The Swedish metropolitan politics have had the bottom-up perspective as a major principle to evolve the democratic participation in segregated areas. My objective was to investigate if a bottom-up perspective has been used as a method of evaluation in a sample of 10 evaluation reports made about democratic participation in Malmö.The key questions were; In the evaluations:- How was the bottom-up perspective and related concepts defined?- What criterias and theories were used?- What values surfaced?- What methods were used?- Has a critical approach been used?The method used is analysis using the theories of Critical Social Method by Alvesson & Deetz, Values in evaluation by House & Howe and Choices of perspective by Eliasson.None of the analysed evaluations have used participatorial methods. As participation is defined mainly statistically, the criterias are usually quantitative measurements, though the evaluators agree that democracy is a matter of quality. There is a common lack of theoretical basis of analysis and methodology description.
The effect of a lowered light intensity at night on cow traffic and milk yield in automatic milking systems
Automatic milking systems (AMS) provide the opportunity for less manual labour and an increased milking frequency. But in order to reach an optimal milking frequency a well-functioning cow traffic is crucial. There are many factors affecting cow traffic but one factor that has not been studied thoroughly yet is the effect of different light intensities during the night, 22.00 h to 05.00 h. Therefore the aim of this study was to determine the effect of different light intensities during the night on number of selection gate passages (GP), milking frequency and milk yield. The study was conducted as a Latin square were three light intensities were applied: LOW (11 ± 3 lux), INT (33 ± 1 lux) and HIGH (74 ± 6 lux), in three different herds.
Pensionärspooler : Pensionär med fortsatt anställning efter ett yrkesverksamt liv
A qualitative survey has been carried out in a manning company whose business concept was to employ pensioners. Six pensioners have been interviewed regarding their views on resumed employment. The results of these interviews have been analysed supported by analytic induc-tion. Areas investigated cover: promotion of better health through work, motivation factors, groupings and control, experience and learning, work and spare time and finally strategies that appeal to an older workforce.The purpose of the survey was to investigate whether the manning company utilizes pension-ers? experience and work skills from their former working life.

Energikonsumtion hos en diskmaskin
The dishwasher is a wide spread product that occurs in many households. It saves the user time,water and energy. When using a dishwasher instead of doing dishes by hand a lot of energy issaved.The importance of lowering the energy consumption does not only come from the consumerwinnings but also from an environmental point of view. Scientists are certain that the globalwarming comes from the emission of green house gasses that is created by human consumptionof oil, gas and coal.Dishwashers today are a lot more energy efficient than older dishwashers, but there are stillmargins to lower the energy consumption. The aim with this project is to investigate thedishwasher and it?s washing cycle, noting different phases and components that contribute towaste of energy.
Språk som maktutövningsmedel En studie om försök att rättfärdiga Operation Iraqi Freedom
The purpose of this study is to investigate the way George W. Bush used the language as a means to exercise power in an attempt to justify Operation Iraqi Freedom. The theories used to answer the purpose are discourse analysis and three different moral metaphors that are applied on the data.The collected material for the metaphors is constituted of cognitive linguistic books from prominent linguists, such as George Lakoff, Alan Cruse and William Croft, and the material for the discourse analysis is also collected from prominent discourse analysts such as Michél Foucault and Norman Fairclough. The official White House website provides the material for my data. The scientific method used in this study has been qualitative text analysis where the hermeneutic approach has been an essential part of it.The main question: In what way did George W.

Växtmaterialet i 1700-talets engelska park : en växtplan för Engelska kullen på Gunnebo
Gunnebo House and Gardens was designed during the late 18th century by architect Carl Wilhelm Carlberg as a summer residence for the wealthy merchant John Hall Sr. and his family. The garden consists of formal garden, kitchen garden and English park. For the first two parts several original drawings have been preserved and here a lot of restoration work has been carried out. This paper aims to examine how the English park might have been implemented during John Hall Sr.?s time and to create a plant scheme for the area called ?Engelska kullen? (The English hill).
Miljövärdering av resurssnål betong med införande i BIM
This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.
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..
