Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

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.

The representative democracy has become weakened during the last decades. At the same time the United Nations declared at the Rio de Janeiro meeting in 1992 that environmental problems can best be solved by involvement of all concerned citizens in decision-making. The main purpose of this study has been to examine if citizens panels is a possible way to involve citizens in environmental decision-making and what the outcomes can be. Furthermore the study has investigated what the participation has contributed to environmental politics and how representative the results have been. This has been carried out by investigating the Piteåpanel in the municipality of Piteå by conducting interviews.The result of the study shows that the involvement of the citizens in the decision-making influenced the environmental politics of the municipality.

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.

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.

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.

In today?s hectic society more and more people experience stress and our lifestyle gives us a very limited chance to recover. For some it sometimes goes that far that they get burnt-out, they have pushed themselves to the ultimate limit. There are different methods and treatments to recover but one very efficient treatment is to spend time in a rehabilitation garden. 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.

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.

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.

This thesis aims to examine how the renowned swedish writer and critic Olof Lagercrantz wrote about communist China under Mao Zedong's leadership in the years 1970?1971. Lagercrantz served as editor-in-chef and as cultural director on one of Sweden's major daily newspapers, Dagens Nyheter, between 1951 and 1975. He travelled to China in 1970 as one of the first European reporters to get admission after the cultural revolution. This series of articles about China also changed the image of Lagercrantz, afterwards he was referred to as Maoist.

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.

This examination studies the gender balance of contemporary art exhibitions in Sweden. To what extent genders are equally represented assumes to be based on how the curating process considers equality work. Three categories of art organisations are studied with the intention to determine differences in equality approach between the categories. Official documents of each organisation are examined to understand how they formally relate to equality work. Statistics of the actual gender balance of each organisation are produced based on the last two years exhibition archives.
