Reducering av markskador vid GROT-skotning
Swedish energy policy aims to increase the use of energy from renewable sources and this should be done in a safe, environmentally and sustainable manner. According to the Energy Agency the use bio-fuel increased by 73% between 1990 - 2006. Stands with high share of slash are often located on areas with high productivity which often are located on soils with poor bearing capacity. This will increase traffic on susceptible soil leading to increased ground damage. To reduce the risk of ground damage at slash-forwarding, ground protection is needed.
Användarvänlighet i blötutfodring : enkätstudie för smågrisproducenter
It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.

Computer Modelling of the Influence of Surface Topography on Water Repellency and a Study on Hydrophobic Paper Surfaces with Partly Controlled Roughness
A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..
OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Dessa har sedan bedömts efter listor av deras respektive för- och nackdelar som kunnat urskiljas.Arbetet visar framtagandet av ett väl fungerande förslag som kan verka som en bas för idéer till nutida och framtida förändringar kring den fysiska planeringen.
Passivhus ur en brukares perspektiv
Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.
Derivativ talan och Corporate Governance. En komparativ studie ur ett rättsekonomiskt perspektiv
The world is getting smaller. Global markets, political processes and communication technology bring people together. Even though many of these processes are dynamic and constructive, they have also resulted in a need for better and more effective ways of international conflict resolution. This thesis investigates central issues connected to the concept of humanitarian interventions in relation to current and future legislation of the European Union. The overall question is whether the rapid globalization process has resulted in a change of international law towards more liberal view where authorization of the security council is not always needed? And, if there has actually been such a liberalization, how does that affect the legal possibilities for the European Union to carry out armed operations without the consent of the global community?The conclusion of the thesis is that international law has been modified mainly in two aspects: First, the concept of sovereignty is no longer seen merely as a right of the nation, but also as a responsibility.
Does Party Politics Matter? - En hypotesprövande studie om USA:s partipolitiska position till europeiskt säkerhetssamarbete
In his recent article Professor of International Affairs Charles Kupchan claims that Party Politics has become increasingly important for American Foreign Policy since the end of the Cold War. This assertion makes it valuable to assess how the substance of the Foreign Policy differs between the two American parties in various cases and if this difference is characterized by consistency or by change. In this thesis I examine these Party positions in relation to the European Security Policy.In order to examine this I compare the positions of the Democratic and Republican Parties? policy concerning both the European Defence Community (EDC) and the European Security and Defence Policy (ESDP). The purpose of this thesis is to examine the hypothesis that the Democratic Party to a higher extent than the Republican Party is more concerned to maintain good relations to Europe respectively EU.The results show that there are small indications that my hypothesis concerning the two parties is valid.
Meddelartrygghet : För privatanställda på offentligt finansierade jobb
This paper examines how notifies security looks for private employed workers in jobs founded by the public. The aim is to clarify the legal situation surrounding notifies law, and to analyze possible shortcomings in the law with a focus on the future.Notifies law is based on five cornerstones. Where freedom of information, a right to provide information to the media for publication, ?acquires the right? and protection to be anonymous when talking to the press goes to all workers. The other two pillars, ?a look up prohibitions? and ?retaliatory forbid? apply only to employees in the public sector.
Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal
Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.
Solenergi på Nya Karolinska Solna
In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.
Frihet, Säkerhet, Rättvisa - En diskursanalytisk studie av Frontex roll i EU:s gränspolitik
This is a study based on discourse theory in purpose to examine the border-politics ofthe EU. Since the EU step by step has developed into an area of free movement on capital, people and services, the external frontiers have been given prioritiy on the political scene. Development in recent years have put questions of foreign- and security politics on a supranational level, meaning that the EU-member states in a wider range now cooperate in these political areas.To handle the increasing ammount of (illegal) migration to the EU an independet agency, Frontex,was established 2005 in favour of coordinating the Member States in issues regarding bordersecurity. The focal point of this study is to critically examine the identity of Frontex by using Becks theory of risk combined with the theory of governmentality. By doing so I seek to highlight the relation between Frontex and the EU and also that of Frontex mission in relation to illegal immigration.
Eskortverksamhet med fokus på försäljning av BDSM-tjänster
The purpose of this study is to examine escort-business with a focus on sales of BDSM-services (Bondage and Discipline, Dominance and Submission, Sadism and Masochism).
The study is based on qualitative interviews with three informants providing BDSM-services, as well as a survey with 96 men who requested domination of escorts (the survey was carried out by an escort in the 1980s). The analysis of this material resulted in the identification of three themes on which the study centers: The personal experiences of the three escorts, the interaction between the escorts and the clients, and the changes over time when it comes to the performance of BDSM-services. The study has a gender perspective with a focus on feminism and queer-theory. The important conclusions are that there are several differences between prostitution having a focus on BDSM-services and other prostitution.
