Möjliga alternativ för att ersätta direktverkande el i flerbostadshus

I have in my thesis, examined the possibilities in terms of energy for a condominium association.To have an effective and good energy is becoming increasingly important with today's rising electric and oil prices. In my thesis I have used the condominium association Kärralyckan, which is situated in Falkenberg. The buildings at Kärralyckan are built in the mid-1970s, and are heated by electric radiators. The tap water is heated by an electric boiler.Based on that calculation I can show the various energyststem. The different solutions have been developed by contact manufacturers and installers through phone calls and e-mail.According to the results shows that geothermal heating has been a great solution for Kärralyckan.

Swedish Open: Konsekvenser av ett evenemang

Syftet med föreliggande studie är att få en ökad förståelse för vilken betydelse tennisturneringen Swedish Open har för Båstad genom att undersöka vilka effekter som evenemanget genererar utifrån en hållbarhetsaspekt.Studien utgår ifrån ett fenomenlogiskt och konstruktivistiskt synsätt. Vidare utgår den från en abduktiv forskningsansats med hjälp av en kvalitativ forskningsmetod. Denna kvalitativa metod görs med hjälp av egna primärkällor som består av tre djupintervjuer med nyckelpersoner som på olika sätt kommer i kontakt med Swedish Open.

Sustainable Construction in the Transportation Infrastructure Industry? as a vision and in practice

This study has been conducted on behalf of Vectura Consulting AB with the purpose to examine how different actors perceive the dimensions of sustainability and sustainable construction. The purpose is also to provide an understanding of existing barriers and opportunities for sustainable construction within the industry and exemplify with different directions for the actors in order to develop sustainability. The study has approach the research problem by using systems theory, developed by Checkland, to identify the relevant system. Other systems theories has been used as an theoretical framework in order to identify barriers and opportunities, which in this study are based on Hughes?s theory about reverse salients and salients.

Nordiskt försvarssamarbete : Är det en ny företeelse eller en fortsättning på det som tidigare ägt rum i hemlighet?

There are changes in Sweden's foreign policy, and Sweden is no longer a non-aligned and neutral nation. Sweden has expressed a willingness to actively participate in creating peace and stability in the world by giving and receiving military assistance in case of war, crisis or disaster. This is described as complete turnaround in Swedish policy compared to the neutrality and non-alignment during the Cold war.However new research shows that defence cooperation is not new in the Nordic region. Sweden cooperated secretly with Denmark and Norway, two NATO countries, about co-operative defence of Scandinavia during the Cold War.Is our historical picture wrong and what we perceive as new and revolutionized not particularly new? Is today's open Nordic defence cooperation a continuation of what was done in secret during the Cold War? The essay investigates and compares two different Swedish defence cooperation?s where one was previously secret and the other is open.

Energivinst vid hybridisering av hydrauliskt system

Today's high oil prices and more stringent environmental requirements have led to that manufacturers of mobile construction equipment try to make their products more energy efficient. With this in mind a project about hybridization of hydraulic systems has been formed. The purpose of this project was to analyze the savings that can be achieved by hybridization of hydraulic systems. A reach stacker truck (Kalmar DRD450-80S4XS) were simulated in some load cases with conventional hydraulic systems and with three types of hybridized hydraulic systems. Different parts of the hydraulic systems were also analyzed separately.

Mänsklig säkerhet i Sudan- För vem och mot vad?

The concept of security is a contested one. The United Nations definition in UNDPs Development report of 1994 is the most authoritive and commonly cited. The civil war in Sudan has led to 2 million deaths and over 5.5 million refugees. In a resolution from 2005, the UN decided that the war in Sudan was a threat to international security and peace. The 10th of January UN decided that a peace commission ought to be send with 10 000 military and civil men including 700 policemen.The main purpose of this thesis is to improve our knowledge of those factors which can cause an increased risk of conflict within a state, and how that can affect the social conditions for individuals.

On the hunt for improvements : possibilities of increasing welfare in captive cheetahs through hunting enrichment

The cheetah (Acinonyx jubatus) is one of the big feline species kept in zoos worldwide. The wild populations are quite small and therefore the captive population make up an important part of the total population of the world. Although life in the wild is not always easy and a captive environment provides shelter and food it does not come without problems. In captivity cheetahs become chronically ill and also develop stereotypic behaviours. Neither of these are problems in wild populations and both can be linked to stress in captivity.

Har antalet naturvärdesträd i Sverige förändrats mellan 1999-2009?

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

Axellagring till Klasserare

GE Healthcare wants to investigate whether additive manufacturing would be an alternative method in their workshops in the Umea? plant. Additive manufacturing is called 3D printing in everyday language and manufactures details by building them up layer by layer in an automated machine. The purpose of this work is therefore to investigate how mature additive manufacturing methods are and how they could be used at GE.The work has been divided into three parts. The first section investigates how additive manufacturing would work in the production workshop at GE.

Normer kring konflikthantering i förskolan

The aim of this study is to enlighten how todays working environment affects young individuals descriptions of how to reach success in work life, now often titled as ?career?. Our purpose has been to analyse how the term career is constituted discursively among young people in jobs characterized by flexibility. The study is based on six qualitative interviews with young adults in the media industry, all between 20-30 years old. By utilising a Foucaultdian discourse analysis we want to expose how the competing and dominating discourses, that our interviewees? statements are based on, can be associated with a wider social context.  The study reveals that our interviewees describe career in two separate ways, both positively and negatively.

Avgång av lustgas från luftningsprocessen på Käppalaverket

The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

Småskalig livsmedelsförsörjning av mjölk :

During the last year?s Swedish agriculture have had difficult times, with decreasing prices and at the same time increasing production costs, which has led to bad profitability and faith in the future. The dairies in Sweden have also had a rough time and there have been large rationalizations during the years. In the beginning of the 20th century there were almost 1700 diaries in the Swedish countryside. There has been a large technical development during the 20th century resulting in a decrease in diaries to only 46 in the whole country today. They are owned by 15 diary companies, of which 7 large and dominate on the market and the rest are small-scale companies. With this development the confidence and feeling for the diary companies also has decreased.
