Tjejgrupp - stärkande eller problematiskt kollektiv? : En analys av erfarenheter och minnen från feministiska tjejgrupper
This essay investigates the results of participation by teenage girls in feminist groups, the so called girl groups. These groups are descendants of the awareness-raising groups of the 1970?s feminist movement. The essay assumes the relevance of theories of heteronormativity and performativity, as well as theories surrounding two different ways to organize girl groups. It is done either through the Pippi-feminism, named after strong independent book character Pippi Longstocking, or through the collective empowerment feminism.
Miljöarbete i försäkringsbranschen : Agria Djurförsäkringar AB
It has become more and more common that companies in the service sector are beginning to understand their own effect on the environment and thus the need to contribute to a sustainable development through acting in a deliberate way. Serious environmental work can help a company to improve their image and in that way win competitive advantage that leads to improved profitability. In a short time perspective, adjustment to the environment is an opportunity to gain competitive advantage and an opportunity to develop a profile. In a long time perspective it is about survival. The environmental work has become a sequel to the work with quality.
Framtagande av OEE-mall
At Volvo Cars Torslanda's paint shop there is a requirement to in a fast and effective way get an overview of the plants capacity. Therefore a capacity template was constructed as a tool for the engineers at Volvo several years ago. This template has during the years become complicated and outdated. Thus this thesis work will resort as a new capacity template, built from scratch. The new template has been built up based on requirements from Volvo and the concept of OEE (Overall Equipment Effectiveness).
Livscykelanalys av en ekologisk bomullsskjorta - miljöpåverkan från vagga till grav
This study includes a life cycle assessment, LCA, on an ecological produced cotton shirt for the company Reflective Circle, which designs ethical and ecological clothes.Initially were cotton farming and textile production studied to gather basic knowledge about the processes. Since this shirt is being ecological produced in the whole production chain, we studied what an ecological production means, but also how a conventional production works. When this was done we could start to discuss the differences and similarities between the production of the shirt and general conventional production.When the LCA was first initiated, the main focus was on the green house gas emissions from the manure at the cultivation. Thereafter the process steps such as picking, ginning, carding, spinning, weaving and sewing were being studied. The picking is done by hand, but the rest of the processes are handed by machines which consumes energy.
Solar energy on Swedish pig farms : a sunny story?
In Sweden there is a large interest in renewable energy but the market for solar power is still small compared to other countries such as Germany. Here many farmers produce their own electricity. The Federation of Swedish farmers have acknowledged the potential for Swedish farmer to produce electricity and there is an interest among the farmers. The agricultural branches in Sweden most suitable for solar power are pig production and poultry due to the even electricity need throughout a year. Swedish pig farmers are going through a period of unsteady profitability which makes it interesting to see whether producing their own electricity can affect the economic situation.

There the patients get treated by therapeutics that uses the garden as the main tool.The fact that gardens and parks have a positive effect on humans have been used by people for a long time but it?s not until recently that the research has taken speed.
Kontroll och kreativitet: En fallstudie av tre reklambyråer
There is consensus in research, policy, business and many other areas around the benefits of creativity. Previous research shows that creativity is only spurred under certain conditions. Usually creativity is not associated with concepts such as control, deadline or cost effectiveness. Companies, by contrast, have the need for control and management of their operations, which implies that the two processes can be difficult to reconcile. A company that wants a high creativity while maintaining control and management is forced into a series of organizational compromises.
Solvärme till Östersunds Rehabcentrums terapibad : Förstudie av förutsättningar för, - och lönsamhet med, solfångare för att värma terapibadet
This report treats whether it is viable to invest in solar heating to heat the therapy pool at Östersunds Rehabcentrum. The rehab center is owned by the county council of Jämtland and is located on Solliden in Östersund city. The solar heating where supposed to be a complement to the district heating that was heating the pool in the current situation. Later, it however showed that this was not the case. The pool is currently being heated by a radiator circuit that is being heated by the district heating.
Manöverkrigets förutsättning : En kvalitativ studie om förhållandet mellan praktik och teori
The term maneuver warfare is frequently used in western defense doctrines and theoreticaltextbooks. The ambition of the Swedish armed forces is to attempt maneuver warfare in allappropriate situations. Theories and doctrines indicate the importance of decentralized command and control systems. Mission command (Auftragstaktik) is one such system and should be applied to all situations of the Swedish Armed Forces. There are theoretical and doctrinal bases for warfare and command, but in practice, what are the preconditions for this? Previous research addresses many theoretical questions but there are flaws in existing studies investigating practical realities.The purpose of this study has been to reach a deeper understanding of armed forces ability to maneuver warfare by analyzing conformity of command and leadership perspectives in practice.This is an interview-based qualitative case study in which respondent´s statements were analyzed and interpreted in relation to a theoretical framework.
Utbyte av massaved och biobränsle i några typbestånd av Contorta :
The aim of this study is to describe a number of type stands of lodge pole pine in Norrbotten with respect on stem volume and total biomass. Further questions to answer is if there is stand characteristics that make the stands more suitable for pulpwood in early thinning, or if it is better to apply whole tree harvest. The study shall also give an indication if bio energy can be an economical interesting alternative for Sveaskog.
Sampled trees represented the variation in the different stands. Five trees were selected from each stand to represent that stand. Stem volume and biomass (kg dry weight (DW) per hectare) for each fraction was calculated.
Hur man vinner ett val i Sverige
Studies have found that the applicability of commercial marketing strategies within politics have increased in recent years as a result of a rising number of swing voters. The purpose of this paper was to investigate the effects of the commercial theory of incongruent information in political marketing in Sweden. Subsequently, an experiment with 742 participants was conducted, testing the effects of congruent and incongruent ad messages for two established Swedish parties. The effect of ad message choice on several well-established measures of ad effectiveness such as awareness, credibility, attitude, conviction and voting intentions was analyzed. The results showed that incongruent information effectively increases attitude, conviction and voting intention for voters who decide on the election day what party to vote for.
Marknadsundersökning inom datacenterbranschen : Undersökning av tekniska inköp, med fokuspå kyllösningar
The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.

Alternativa produktionsmetoder vid anläggningsarbeten Kringgjutning av el- och telekabelkanalisation
I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.
Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
