Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.

Sedan 2005 redovisar alla koncerner inom EU enligt normer och standarder framtagna av IASB. Övergången till dessa internationella, gemensamma redovisningsstandarder ämnar skapa större möjlighet för jämförbarhet mellan bolag och skydda investerare. Noterade bolag vid Nasdaq OMX Stockholm kommer årligen ut med en bokslutskommuniké som är den fjärde och sista delårsrapporten. De resultatbegrepp som ska användas i denna är reglerade enligt IAS 1 och IAS 34.Denna studie ämnar undersöka om det förekommer andra resultatbegrepp, så kallade non-GAAP measures, än de reglerade, i 204 bokslutskommunikéer från noterade bolag vid Nasdaq OMX Stockholm 2009. Huvudsyftet har en deskriptiv ansats och ämnar besvara i vilken omfattning alternativa resultatbegrepp förekommer, hur dessa benämns och om förklaringar ges till begreppen.

The purpose of this essay was to study some selected magazine articles by examining how the concept of child poverty is produced in the public debate, and to see if the definition of the term has changed over time. The theoretical approach on which this study is based has been used as a tool to provide better understanding on the subject. Furthermore, theories of consumer society, the "collateral damage" and the theory of welfare regimes have been used. In the previous research presented in the paper focuses on linking children and families living in precarious economic conditions, consumer standards and welfare systems that characterize society.This study has a qualitative approach as it attempts to capture and increase understanding of how the concept of child poverty can be understood from a Swedish context. The study is based on newspaper articles that are studied using a structural text analysis.

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

The Security Council?s resolution 1325 addressed the major negative impact that armed conflict has on women and children. This in turn complicates the Council?s work on maintaining international peace and security. The resolution therefore highlights women?s rights as participants in peace- and conflict processes.

The aim of this paper is to try to explain how specific, foreign policy decisions are made, and why one state decides to use violence against another state. A qualitative method is used, and text and documents are analysed. The two theoretical points of departure are central within foreign policy analysis: realism´s theories on external threats and constructivism´s theories on ideas´ policy influence. The empirical case chosen is the US decision to use military violence against Iraq. The paper investigates whether the real threat from Saddam Hussein´s Iraq was the cause of the American military attacks, or whether the ideas of leading politicians in the USA were decisive for the decision to invade the country.

Abortion remains a contentious issue, which greatly raises ethical problems. This thesis examines the leading arguments in the Swedish abortion debate around the ? in terms of legislation ? critical years of 1938 and 1974. With Foucault's genealogical method, Butler's theories of gender as a social construction in relation to power and doxa, the study examines what the development of the argumentation says about the views on morality, the woman's body, life, individual and state? How has the arguments pro and against abortion changed over time and what does this say about the norms that guide and orientate the arguments? The most obvious change in argumentation is seen in the shift from an absolute moral and conservative position into an increasingly relativistic and liberal position, and this study will argue that this shift has its prerequisites in the changing status of the citizen and state.

The case study investigates study association representatives? perspectives on the activities of the popular education within the social sector in Örebro and why they are organized. It further investigates the cooperation and dialogue between the study associations and the municipality of Örebro regarding this activity. The study is based on critical realism. A questionnaire survey was conducted among all ten study associations in Örebro, combined with qualitative interviews with representatives from six of the active associations.

The Swedish state and educational system are secular, so to say they do not depend on the former protestant state church anymore. Many people in Sweden are also secular. Even so, in school teachers meet students with a religious faith. The purpose of this study is to examine how teachers without a religious belonging experience the encounter with religious students. The method used was semistructured interviews with five teachers in a upper secondary school in a multicultural suburb of Stockholm.

Every second woman in Sweden suffers in their lifetime of fracture that is related to osteoporosis. Osteoporosis and fractures affect the person´s everyday life. The aim of the study was to describe experiences of feeling well among women with osteoporosis. Six women were interviewed with semi- structured interviews. The interviews were transcribed and the text was analyzed with thematic content analysis.

During the last decades the fertility of dairy cows has declined in the same rate as the milk yield has increased. This is a result of the negative genetic correlation between milk yield and fertility, failure to show estrous signs and metabolic problems in the cow. The purpose of this review was to investigate the function of metabolites and hormones as markers for disturbances in fertility, health and production in the dairy cow. There are several metabolites that are suggested to indicate the cow?s energy balance.

Effects of climate change, urbanization and global homogenization are resulted in the degradation of land and losses of natural habitats. Ecological design integrates nature into urban environment by respecting natural ecological principles and processes and creating resilient urban biotopes which also can be used by local urban communities. The aim of the thesis is to answer the research questions: How ecological design principles can be applied for re-design of Toledo Riverfront (with requirements of the design competition)? and What is the ecological design in landscape architecture? I participated in the USA design competition with the aim to create a vision and redesign of Toledo Riverfront in Ohio State, USA. The site is located in the south point of Lake Erie. As a result of a long industrial activity, riverfront of Toledo had been transformed into inaccessible and abandoned brownfields. In my proposal I applied ecological design principles on three scales: the city of Toledo by reinforcing of ecological connection and creating green corridors along the river; the intermediate scale by suggesting public parks along the river front and on the fine level by proposing detailed design including remediation of the site and use of dredged material.

The Swedish healthcare systems have over the past decades experienced a major reorganization that involves reduction of costs and cuts due to the financial problems that the public health system faced. Healthcare was criticized because it was considered to be bureaucratic and inefficient (Funck, 2007). The solution to this problem was to focus on other measures rather than the economic measures, such as modernizing the healthcare instead of cutting down. Implementing a balanced scorecard in a public sector as a hospital, perceived as failures. This is due to several factors such as communication, knowledge and expected time are not taken into consideration when implementing the scorecard.

It is extremely important that the construction of the environment where children and youngsters spend the majority of their days supports the progress of their mentality. That is why I in this study will investigate what a certain amount of teachers consider of the interplay between learning and environment and how they thought a satisfactory environment structure eras of learning and also what the teachers consider to be missing at this point.The schools where I gathered my material are located in Thailand but they use the Swedish curriculum as a starting point and the students at these schools are mostly Swedish speaking.An important element that I came across was the impact of the surrounding on how to shape and use the environment as a tool in the teaching. Thailand?s climate is different than the Swedish climate; I want to investigate if that has any effect in the teaching.The educational environment in schools includes not only the classrooms but also every other space closely connected. Earlier scientific research as well as those people that I used as objects for interviews agrees regarding the fact that a suitable and stimulating environment are one of the most impact on how well children learn.

The study has been conducted to find out whether aesthetic expressions and experiences can benefit the smallest children's language development. How do the teachers at the preschool relate to aesthetic expression? Do they think that aesthetic expression and experience will be favorable for stimulating children's language? Children perceive through their senses, logically aesthetic expressions should promote children's learning and development. How does this claim stand in relation with the smallest children's language development and teachers' views on aesthetics as a pedagogical tool for language stimulation? To get closer to the answer a survey have been done.
