This thesis reports on a case study of a forest company, Stora Enso, and their experience from a number of trials and experiments with ash recycling. A literature survey and a total of eleven in-depth interviews were carried out. Ash recycling was found to be the concern of three different divisions of the company. The pulp industry which produces the ash, the forest division which would be responsible for identifying land and spreading the ash, and Stora Research, which has had a major part in the design and implementation of research trials. Lacking an overall company decision on ash recycling the matter is left to the individual divisions.

The purpose of this thesis is to study how homosexuals and homosexuality were represented in the press during the trials against the Pentecostal pastor Åke Green, and to what kind of social representations and narratives these representations can be related.Using critical discourse analysis and theories about the differentiation between in- and outgroups I try to unveil implicit meanings and attitudes towards gay people mainly at the local text level. The material consists of articles in Ölandsbladet and Dagens Nyheter that were produced before, during and after the trials.The analysis suggests that homosexuals are construed as a deviant outgroup and that the majority, the ingroup, is presented as an essentially heterosexual, tolerant community. Homosexuality is wrong and heterosexuality is the right way of living. Homosexuals, in terms of group lobbyism, are construed as an enemy, a threat, against Western ideals such as family values and freedom of speech. They indirectly become a threat to Swedish democracy.

The purpose of this study is to investigate witch knowledge and thoughts children will have about the term of floating and sinking, and witch possibilities there is to make various knowledge visible in preschool physics through playing with water. The study also concern the differences and similarities between two different groups of age who have participated in the study. The study was carried out by an activity with participant observation and feedback interviews afterwards. The result shows that the possibilities to physics are many in preschool. The children expressed new thoughts and ideas who concern other phenomena in physics during the investigation and discussed similar experiments and material to examine.

There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

Firewalls protect network traffic and decide witch traffic to send further and witch traffic will be blocked. All this depends on the rules in the firewall. The firewall is installed between the internal network and the Internet. It is difficult to find a firewall that can protect us against different threats. Firewalls have both advantages and disadvantages and all this make them vulnerable.

Regeneration with scarification and planting is a well known method, but the plants have a tuff period in the beginning. Decease of plants comes from pine weevils, dry weather, browsers, wrong method of scarification and wrong time for the planting. These are some courses why not every planting gets successful. The purpose with this study is to investigate witch time of planting gives the best result, spring or autumn planting and to give a answer of witch factors are the main course of deceases. The goal is to have the study to decide witch time to plant after final felling. The choices of plantings were maid from a period of three years. Spring plantings were from year 2005, 2006 and 2007 and autumn plantings were from 2004, 2005, and 2006.The purpose was to compare differences in deceases at the same spring weather.

This report was performed in order to evaluate a new technological measure and focuses generally on a heat pump system to a HWC-washing machine. The client is Asko Appliances AB, a company well known for its environmentally friendly products. The goal of this study was to improve the energy efficiency of a washing machine by combining a heat pump device to the heater of the wash water, in order to reduce the energy consumed for heating the water. Besides reducing the energy consumption in heating the water, the washing machine was required to meet low noise and short operating time specifications. For that purpose, nine trials in three test series have been carried out.

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Alpha-linolenic acid from flaxseed oil and effects on blood pressure ? A systematic reviewAuthor: Christine Hårdfelt och Liduina van SitterenSupervisor: Helen LindqvistExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 9th, 2014Background: High blood pressure is strongly associated with an increased risk of developing cardiovascular disease, particularly stroke. ALA-fatty acids have previously been associated with decreased blood pressure. Flaxseed oil is very rich in these fatty acids and has also been highlighted as an affordable and sustainable source.Objective: To investigate whether ALA-fatty acids from flaxseed oil may affect blood pressure in people with high risk for cardiovascular disease.Search strategy: Two searches in PubMed and Scopus were performed. The sample was specified by using specific keywords.Selection criteria: The criteria for inclusion of studies required that flaxseed oil was compared with a control and that blood pressure was measured as an endpoint.

Due to the new demands put upon combat vehicles of today the development quickly strives for-ward. With developers and experts across the globe working to meet the needs of tomorrows armies. The question we ask ourselves is what will be the characteristics of these vehicles. In order to be able to categorize combat vehicle and analyze its characteristics we use the principles of war. Based on J.F.C Fullers theory from the early 19 hundreds that anything can be analysed using these principles, through a modern interpretation of the Swedish army, we can categorise the present and future abilities of combat vehicles.

Postcolonial feminist theory says that ones identity is constructed by severalfactor, not only gender but even culture, ethnicity and class imbedded in the socialcontext. This paper examines what happens to women's identities if the socialcontext changes. Does an identity shift occur? By interviewing five women fromBosnia-Herzegovina I try to understand the affects migration has on women?sidentity. Postcolonial feminist theory says that our identities are constantlychanging, as their constructing factors.

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.

Fair trials? rights under Swedish law of public administration (FL) are regulated by Article 7 of the Statute. Similarly, fair trials? right under the European Convention of Human Rights (EU Convention) is regulated by Article 6.1. The essay conducts a comparative study of the two legislations and seeks to determine whether Article 7 of the Swedish law of public administration is consistent and compliance with Article 6.1 of the EU Convention.

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.
