Analys av framtidens system för hantering av avloppsvatten och matavfall i Eskilstuna

Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling

Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.

Herrelösa katter i Skåne : problem och hantering

The large number of surrendered and feral cats is a big animal welfare problem all over the world. Populations of feral cats arise through a large number of unwanted cats which can lead to surrender of these, through cats allowed to roam free outside which can lead to the owner losing these and through the reproduction that occurs amongst these surrendered or lost cats. One aim of this study is to give an account of this problem. It is however difficult to draw general conclusions about these populations of cats since studies all over the world has been carried out on different types of populations, during different conditions and different periods of time. The welfare of many of these cats is presumably low because they are exposed to risks as disease, starvation, climate, traffic, other animals and humans.

Budgetstöd : relationen till de svenska biståndspolitiska målen: att skapa förutsättningar för de fattiga att själva driva sin utveckling, uppnå jämlika förhållanden mellan givare och mottagare och fattigdomsbekämpning

There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.

Miljökommunikation i dagspressen : En diskursanalys av hur SvD och DN framställer miljöfrågor

The starting point of this study is that the news media in general strongly influence which topics determine the public agenda by their choice of what is considered newsworthy. The study is based on articles from two major Swedish daily newspapers, Svenska Dagbladet and Dagens Nyheter. The aim of our thesis is to establish how the environmental public debate as portrayed in the newspaper corresponds to the environmental discussion within the scientific (subject matter expert) field, that is taught by the academic institutions, or if the two materially differ. The environmental communication discourse at the academic institutions advocates ?episodic? formation as the driving force behind transformation of attitudes and behavioral preconceptions. This episodic formation is aimed at incentivizing change by creating intimacy to the incident by linking cause and consequence to the individual citizen instead of to society as a whole.

Design Program for Dessie Campus, Wollo University, Ethiopia

A geographical position and its social, cultural and political context as well as climate and specific physical characteristics define the scope for a landscape design project. This has become clearer for us in our master project where we have made a Design Program for the outdoor environment of Wollo University in Dessie, Ethiopia and analysed and reflected on the work and process. The aim for the project has been to design an attractive and functional outdoor environment for the Campus, based on the inventories and the needs and wishes of clients and users. But, the aim has also been for us as landscape architect students to gain a greater knowledge about landscape architecture and the design process by position ourselves outside our usual context. The method has been open and seeking where the site, literature studies, dialogues with people and our own experiences from the field study in Ethiopia has influenced the work. Wollo University is situated 400 kilometers north of Addis Ababa, in a mountainous landscape. It faces problems of heavy rainfall during the summer, soil erosion, a lack of essential facilities, and is still a construction site with empty spaces in-between buildings and infrastructure.

Ung och stressad : En kvalitativ studie om unga tjejers upplevelser och hantering av skolans krav

A considerable number young of students are suffering from sociopsychological complaints. The psychological complaints emerge from differnt sources. Important factors for psychological well being are experiences of a satisfactory social network, efficient coping strategies and a supportive school climate.The aim of this study was to examine how young girls in the age of 16-18 years old experience and cope with demands from school. To fulfill the aim of this study we have five questions: What do the girls apprehend as a satisfactory/unsatisfactory working environment? How do the girls define stress? How do the girls cope with stress? What importance has leisure time? What importance has the social network? The method we used for this study was qualitative and the material was collected through four focus groups.

Riskkapitalinvesteringar i svensk miljöteknik - obalans mellan utbudet och efterfrågan?

Earth?s resources have been exploited unsustainably. If an entire conception of exploitationof natural resources does not change now, this will entail enormous costs in the future.This insight has lead to a recently increased interest in clean technologies among privateequity capitalists. In the fourth quarter of 2006 about 10 percent of all private equityinvestments made in the US market were placed in the cleantech industry. Despite a goodinvesting climate in Sweden, Swedish capitalists have shown little interest in cleantechinvestments.

Pallaskattens (Otocolobus manul) beteende i två djurparker - påverkan av hägndesign och miljö

The Pallas cat is a small cat living in central Asia. The cat is approximately the size of a domestic cat but the Pallas cat is more stocky build and has a much thicker fur that enables the cat to live in a climate with temperatures plummeting to -50°C. The thick fur is one of the reasons this cat has been a popular game for hunters in the past. Nowadays there are other threats to the Pallas cat. One of the major threats today is the reduction of food sources.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron

In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.

Inverkan av nederbörd, temperatur och frost på årsringens egenskaper hos boreal tall (Pinus sylvestris L.) :

The wide distribution range of our boreal pine (Pinus sylvestris L.) provides a great variation in growing conditions and climate/weather factors that influence the wood development of the trees. A great number of extensive studies have been conducted over the years in order to clarify growth trends of this and other species over more or less wide-ranging areas. In this thesis effects of weather factors were instead compared between different forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and silvicultural treatment; fertile ? high stem density, fertile ? low stem density, poor ? high stem density and poor ? low stem density.

The Psychology Driving&Barriers to Skunk Work Project

The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.

Integrerade ledningssystem : Drivkrafter, möjligheter och hinder

The world is changing and the business context is no exception. One of the clearest tendencies is a tougher business climate with harder competition due to increased international trade and the expansion of the e-business. At the same time the customers are becoming more sophisticated and demanding. The last decades have also meant that tougher and more frequent demands are being aimed at the businesses from a wider variety of stakeholders; demands regarding how environmental issues, social responsibilities and business ethics should be dealt with. All of the above have driven companies towards implementation of different management systems to be able to cope with the demands as well as to ensure that these issues are being dealt with in an efficient and effective manner.
