Energisystem med utnyttjande av restprodukter för gödsling av Salixodling för energiproduktion : studier av kretslopprojektet i Enköping och dess applicering på en kommun i Ryssland.
The purpose of this work is to study a circulation project in Enköping municipality, where the society?s rest products are used to make beneficial products. In Enköping the rest products from waste treatment plants and private sewers are used to fertilize and irrigate Salix plantations that later are harvested and burned at the local combined heating and power plant, ENA Energy AB, to produce electricity and heat. Possibilities to apply this kind of project ona municipality in Russia are also explored.Guryevsk municipality in Kaliningrad region was chosen since there is a need to improve energy systems and reduce emissions to water and air. This municipality strives to become environmentally friendly.
Energieffektiviserande åtgärder i samband med renovering av flerbostadshus
In Sweden, a big part of the energy use is used in the housing sector. Political goals and targets are set up which the housing sector needs to work towards. Apartment buildings are a major part of the housing sector in Sweden and therefore reduction of energy use in these kinds of buildings are key to lower the energy use in Sweden. But there are not only political incentives to reduce the energy use. Some energy?saving measures are directly profitable and should thus be performed.
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..
The Consumer as Barrier vs. The Consumer as Partner
First objective: To bring forward managers? perceptions of the underserved consumers in emerging markets. Second objective: To reveal what implications managers? perceptions of underserved consumers in emerging markets provide for branding in these markets. Our study indicates that managers? perceptions are still lacking consumer insights within five elements (value, loyalty, purchasing power, consumers and consumption).
Passivhus ur en brukares perspektiv
Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.
H?LLBARA INTERMODALA TRANSPORTER I EU En studie om EU:s transportpolitiks inflytande p? samverkan mellan transportslag f?r h?llbar mobilitet
The transport sector is one of the biggest pollutants in the European Union. In relation to
transport policies and environmental policies, intermodal transportation solutions are of high
relevance to establish a sustainable transport sector for the future. Intermodality which is
defined as smooth transition between transport modes is a key figure for how modal shares
are divided between the modes of transportation. The aim of this bachelor?s thesis is to
examine the research gap whether policies intended for a specific transport mode affects each
other in relation to EU policies intended for intermodality.

Bloggens betydelse för unga kvinnors självkänsla
Med denna C-uppsats vill vi belysa bloggens betydelse för den unga bloggläsaren i Halmstad och Laholmskommun. Genom tre teman som är konsumtion, livsstil och intrycksstyrning vill vi få en ökad förståelse för bloggens betydelse för den unga kvinnans självkänsla med fokus på bloggläsaren och bloggerskan. Metodtriangulering var grunden för vår metodologiska utgångspunkt. Vi har tittat på skriftliga källor, tidigare forskning och tre bloggare som vi sedan intervjuat. Samt en enkätundersökning som utfördes bland elever på olika gymnasieskolor i Halmstad och Laholm, vi lämnade ut totalt 105 enkäter. För att ge undersökningen en bättre bild av hur läsaren upplever bloggen intervjuade vi även tre bloggläsare. Vi har kommit fram till att bloggen har stor betydelse för den unga kvinnans självkänsla och vi belyser detta ur en bredare kulturell synvinkel. .
"I en optimal värld skulle det inte se ut som det gör idag" : En kvalitativ fallstudie om vad som ha?nder na?r kravdokumentation inte tas pa? allvar
Requirements engineering is a widespread topic in the research field of informatics. However, there is little research regarding lack of requirements documentation and how it is perceived. The same applies for how requirements engineering in retrospect can be implemented. This is a debated issue on blogs and forums but it has not been reflected in the research area.Therefore, this study concerns research questions regarding how the developers, testers and requirements analyst experience the lack of requirements documentation and how requirements engineering in retrospect can be implemented.To answer these questions, data collection has been conducted through qualitative interviews with individuals affected by this problem in their everyday work.This study has provided an explanation of how the problem is perceived and what the consequences are, both direct and indirect. The impacts are divided into three categories and are presented as, emotional consequences, system implications and consequences regarding re source consumption.
Ser det inte lite lika ut? : En kvalitativ studie av den icke stylade bildens potential att inspirera individen
Purpose: The purpose of this study is to investigate the effect and potential of a non-styled home reportage, and how they influence and inspire to promote individual creativity.Method: I have used a qualitative analysis to be able to create a deep understanding. This is based on three interviews with women in age 22-27, which have a dedicated interest in interior design. I have also sent questionnaires to two persons who run interior design blogs.Conclusions: My analysis shows that the non-styled home reportage is the start of an inspirational process that is beyond consumption and status objects. It promotes individual creativity and willingness to create, based on personnel taste. The essay highlights the importance that the individual critically examines the aesthetics of interior design as presented in diverse media.
En exakt konst: : (Re)produktion och gestaltning av makt och normalitet genom mat och måltider i Virginia Woolfs Mot fyren
The aim of this essay is to analyze how food and meals produce and reproduce values and power relations and how these processes are portrayed in Virginia Woolf?s To the Lighthouse. Using sociological writings in the field of food consumption and production I study the structures that affect our relation to food and eating. This perspective is combined with a phenomenological view, aiming to examine how food is perceived, which is also inspired by queer theories. Using the method of close reading, the theories are applied to Woolf?s work.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Framtidens bank : en studie av hur banker skulle kunna utformas med hjälp av användbarhet och social media
The retail banks are usually looked upon as conservative. Since the launch of internet banks in the 90's they have not developed much. Meanwhile the internet is developing in a fast pace and social websites are increasing in popularity. The purpose of this essay was to investigate how internet banking will develop in the near future based on interviews, literature and trend studies. With web 2.0 techniques the internet bank could develop to help the costumers take more informed decisions regarding their economic situation.
INDUSTRIALISERING AV FLERBOSTADSHUS
The construction process which is used today while constructing residential buildings has for along time remained unchanged. Unfortunately the development process has gone away frombecoming industrialized and instead most of the work is done at the construction site. In thisrespect this is a worse alternative because the project outcome will be more expensive and theconstruction time will be longer. Skanska?s vision is to have a process which is more like the oneused in small residential buildings which is fully industrialized.The constructing process for residential building involves more parties and therefore it becomesmore complicated.
Metoder för kartläggning och analys av nätförluster i lågspänningsnät
An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.
