A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.

The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.

In the 1980?s the moose population in Sweden grew explosively due to big changes in the silviculture with clear cuttings instead of single-tree selection. Clear cuttings brought big areas of young forest and therefore a lot of fodder in one place. Since this change, the discussion about how to manage the moose population has grown into a very big problem. Forest owners think that the population needs to be strongly reduced because of all the damage that is done to the young forest when the moose seeks its food, and the economic losses because of that.

Artificial insemination (AI) has had a great influence on the development of pig production and is today widely practiced (Gerrit et al., 2005). With AI, genetic progress can at a short period of time be spread worldwide compared with using natural service and the best boars can be intensively used. This is also one of the biggest risks with AI; the impact of semen containing a genetic disease or contamination of pathogens can be enormous. Fortunately, it is a small risk of disease transmission due to many tests of the boars and the semen before use (Maes et al, 2008). It is important that the boars used for insemination have good breeding values along with good reproduction features and have good fertility results (Robinson et al., 2005).

SAMMANFATTNINGTitel: Valutariskhantering vid rörelseexponering - En kvantitativ studie av svenska börsföretagNivå: C -uppsats i ämnet företagsekonomi.Författare: Gustaf Bergquist och Jimmy Mattsson.Handledare: Peter Lindberg.Datum: 2015 - juni.Syfte: Syftet med studien är att studera förekomsten av skillnader och likheter mellan svenska börsnoterade företags hantering av rörelseexponering mot valutarisk beroende på vilket segment de tillhör på Stockholmsbörsen.Metod: Studien är av kvantitativ natur med en deduktiv ansats. Data har samlats in genom internetbaserade enkäter som sedan har ställts mot tidigare forskning och teorier. Utfallet har sedan analyserats genom korrelationsanalys och presenteras tillsammans med resultatet.Resultat & slutsats: Studiens resultat visar på förekomsten av flertalet skillnader och likheter vad gäller hantering av valutarisk som kan kopplas till segmenttillhörighet. Den slutsats som dras i studien visar att benägenheten att skydda sig för rörelseexponering mot valutarisk och att hantera valutarisk internt är störst hos företag på Large Cap och att benägenheten att ta hjälp externt vid valutariskhantering är störst hos företag på Small Cap. Gällande förekomsten av storleksrelaterade likheter visar studien att dessa är relativt små.Förslag till fortsatt forskning: Då denna studie är av kvantitativ natur skulle det i framtiden vara intressant att komplettera enkätundersökningen med intervjuer för att ge en bättre förståelse kring valutasäkringsprocessen.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.

During the period 2009-2013, investments in the Swedish national grid increase by a factor of ten compared to previous years. In order to fulfil their mission to manage the national grid in a safe, efficient and environmentally sound way, Svenska Kraftnät (Swedish National Grid) needs to take all these perspectives into account while planning new investments. To compare and relate perspectives of technology, economy and environment the same yard stick must be used. That yard stick is commonly money. A problem arises however as environmental issues are difficult to price.The purpose of this master?s degree project was to develop a tool for evaluation of environmental impact related to investments in the Swedish national grid.

Low stumps represent on their own up to 80% of the dead wood remaining on clear cuts and therefore supply suitable habitat for saproxylic insects i.e. insects depending on dead wood for their survival. Recent stump harvesting activities threaten this substrate of ecological importance and increase the anthropogenic negative impacts on these species. Because of technical and environmental reasons (nutrient leakage, erosion) guidelines for stump harvesting recommend to retain stumps standing in wet parts of clear cuts. However, stumps in wet positions might not be a satisfactory substrate for saproxylic insects and therefore might not be as much used as stumps in dry positions.

Not enough attention has been paid to the correlation between the failure of peacekeeping operations and the actual source of civil wars. This text is an attempt to fill that gap. Hence the question: under which conditions is it possible for peacekeeping operations to replace the responsibility of the state concerning the security aspects of the social contract? The outset of the text, using the theories of Robert Nozick, is a theoretical approach towards the founding of states, described as the merging of entities. The theory serves a purpose since it, in combination with identity, illustrates in what manner the glue of society occurs and the rallying around other kind of loyalties like clans and ethnicities.

Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. Therefore, measures affecting forage quantity and distribution might be a tool to reduce the economical losses in forestry without decreasing the ungulate densities and thereby decrease the conflict between different interest groups.This study investigated the potential biomass production and utilisation of marrow-stem kale (Brassica oleracea var. medullosa), at game fields in Misterhult, Sweden, as well as browsing effects on adjacent forests.

Miljöbron is a non-profit organization; their main purpose is to merge companies and students into different environmental projects. The projects can be an assignment, practical vocational training or degree thesis. Miljöbron is expanding and the demand from students and companies is rapidly growing. Because of the expansion, a large amount of information needs to be stored and managed in a structured database. Also the need of a interface that is structured and easy to use when managing information and Miljöbron?s statistics, for Miljöbron?s staff.

During 2009-2010 Sweden participated in an international military operation whose intention, according to the Swedish news media, was to fight Somali pirates. The purpose of this thesis is to study various decisions and documents behind the Swedish efforts, both military and foreign aid, regarding the matter of Somali pirates during the years 2009-2010 and analyze the results using an interpretation of the security-development-nexus-theory. The method used is text analysis based on the hermeneutic idea of understanding and interpretation.The thesis studies the international resolutions and national decisions that lead to the military operations in the Gulf of Aden and also the international strategies and national approaches regarding Sweden's assistance in the development of Somalia. The theoretical section contains an interpretation of the vast security-development-nexus-theory. The concepts of security and development are first presented separately and then collectively in terms of military security, societal security, economic security, regime security and human security.

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.

In this paper discourse analysis on the Ethiopian National Action Program (NAP) to combat desertification is made. The aim is to describe how the overall image/picture of desertification, its causes, and effects and of possible solutions are presented in the NAP. The result of this analysis shows that the main cause of desertification is human activities mainly due to the poorly developed socio-economic situation in the dryland areas. It is indicated that an excessive dependency of the rural population on the natural resources, particularly land, is the major cause of land degradation and this deterioration of land is said to have been caused by the rapid population growth, overgrazing, forest clearing as well as past government and institutional failures. In addition it is indicated that the effect of desertification usually involves ecological changes that sap land of its ability to sustain agriculture and human habitation, therefore the most serious threat to human welfare.
