The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

This report is intended to give an insight in the Network Performance Assessment Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..

The purpose of this study was to examine how school personnel describe and interpret the phenomenon bullying among girls, and also what their interpretations are based upon. More specifically its aim was to find out what characterizes and causes girl-to-girl bullying, according to school welfare officers and teachers. We wanted to find out how school personnel look upon aggression among girls and social expectations on girls behavior. The analysis was based on two kinds of perspectives: one focusing on gender and one focusing on power in relationships. Research shows that girl-to-girl bullying is hard to observe and that this problem has been invisible in earlier studies.

This paper examines the possibilities of using video games as a tool for education of virtue ethics. By comparing learning aspects in Marc Prensky?s theory Digital Game-Based Learning and Aristotelian virtue ethics, this paper tries to look for similarities in how each theory looks at learning. Prensky?s theory is about how one can use video games in education, which is why it is used here.

According to the Swedish Bankruptcy Act (SFS 1987:672) legal transactions can be reopened in cases of bankruptcy, if the transactions have been the cause of or were performed while the debtor was no longer solvent and thus harming the creditors. The legislations of the Bankruptcy Act chapter 4 §5 aim to protect creditors so that the debtor cannot withdraw their property in case of a forthcoming bankruptcy, as well as prevent creditors from taking measures against the debtor when the debtor is in financial difficulties. However, according to the Swedish jurisprudence there is a hierarchy as of according to which legal rules a legal transactions shall be enquired in case of bankruptcy. Firstly, a legal act must be valid, the transaction must thus be valid accordingly to either the law of contract, the law of property or according to the rules of corporate law. Each of these three legal areas have their own rules of annulment and any legal act has to be valid in accordance to any of the rules above before an action of reopening the transaction according to the Bankruptcy Act may be brought before a court.

Problem discussion: Syncron experience a challenge in realizing the full market potential of its newly developed IT-based price management system, Global Price Management (GPM). The system has already been implemented and is currently running with success within the IT-structures of the first customer. The fact that the development of the system has been initiated by a customer, and thereby has left Syncron oblivious of the real underlying drivers and incentives for the development, is part of the problem. Understanding the customers? incentives for developing their pricing process thus reducing the application uncertainty is a good starting point.

Humans have always been fascinated by the thought of bringing non living objects to life. We wanted to explore the possibilities of trying to create an artefact that the audience would consider possess emotional states and have a life of its own. TaS is a interactive chair that functions as a social entity. The idea is to try and enhance the bond between human and artefact, based upon the emotional connection. We try and produce, enhance and maintain this bond through curiosity based interaction.

The purpose of this study was to compare naturally regenerated Scots pine (Pinus sylvestris (L.)) against seeded Scots pine in terms of benefits and differences. An inventory was performed at a number of different sites, 4 ? 6 years after soil scarification and data on the number of new established plants, their height growth as well as ground-line diameter was collected. Information about site conditions such as altitude, quarter exposure and frost risk was also collected. A review of previous studies was conducted in addition to the field study.

The dog (Canis lupus familiaris) is the first species ever domesticated. They can develop a close bond towards other dogs, almost like a relationship among siblings, which can be a high valuable resource for good relations and cooperation?s. Dominance in dogs is sometimes used to explain undesired behaviors and explained as a personality trait. Dominance though, is not a trait in a dog or a source for undesired behaviors, but can rather be explained as a relationship between individuals, were one of them receives more submissive signals from the other.

This paper will portray the differences and similarities that exist between students whoattended the Swedish School of Library and Information Science in Borås.The study is based upon quantitative information gathered from a survey which wasdistributed to first-year students in Borås in the auturnn term 1994. A total of 77 studentsresponded to the survey.We also do a comparative study of the students at all the library programs in Sweden.This is partially based on the findings by a thesis prior to this one by the authorsSvalstedt and Österdahl.We found that the students in Borås differ mainly in their personal histories and backgrounds.When it comes to their attitudes towards the profession and educationalmatters they are similar. Further we found the same to be tme in our comparison of thelibrary programs in total..

This report is a case study of ?citizen forums? in the municipality of Uppsala. These forums are arranged to make people participate more in local politics. The aim of this study is to find out if the opinions and the wishes coming from the citizens are later involved in the planning process etc made by the authorities. The aim is also to explain why or why not the opinions from the citizens are of any importance.My empirical data come from interviews that I have made with seven different respondents, both politicians and civil servants.

The main object for this thesis is to study how students in library and information science at Högskolan i Borås search and valuate documents in the process of writing a paper. The study is based on a series of interviews with 12 students. Our methodology is also based on studies of their final product. The goal of the study was to map out how the students make their decisions during their search process. We studied the students use of search words, relevance judgements and how their need for information changed trough out the writing of their paper.

Many theories describe failed states as potential threats to international security due to the breeding ground they constitute for transnational terrorism. Ken Menkhaus believes however that transnational terrorists are dependent on a state for their own protection in order to be able to operate.This essay seeks out the relevance in Ken Menkhaus? theory which states that transnational terrorists rather exploit corrupted states than operate in countries where there is a state collapse. His theory will be applied on a case study on post-Libya after Gadhafi?s fall.

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

In light of the European Union`s 2012 theme year: Active aging and solidarity between generations I wished to gain an understanding of weather elderly immigrant are provided with equal possibilities and access to local community information as the majority population and their participation in activities arranged for senior citizens in the municipality where they live. I have done this by meeting with those who work in this capacity. I also chose to meet with representatives for immigrant organizations in the local community to enquire of their work with senior citizens within their own ethnic group. This is a qualitative study on a phenomenological ground based on nine interviews and four observations. I have had two theories to help me analyze my empirical material.
