The City of Stockholm has decided to invest in renewable energy and especially in photovoltaics. The objective of this thesis is to investigate the photovoltaic potential on roof areas that the city possesses and to further investigate some buildings of the Property Management Department. The thesis also compares some existing photovoltaic plants with the solar irradiance map which shows available roof area on each building in Stockholm. The report ends with a literature study about the climate impact and greenhouse gas emissions of photovoltaic.The total available roof area suitable for photovoltaic plants is estimated to 700 000 m2, with a potential electricity production of 110 GWh per year. This corresponds to 17 % of the City of Stockholm?s yearly electricity consumption.

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

The value of a company's employees is considered to be higher and more important for a business success than ever. Losing employees is not only a loss of valuable knowledge, it also implies a significant cost related to the recruitment of new employees. To attract potential personnel, it is important for the companies to understand how to communicate with talents. Choosing a communication medium for a job advertisement is not easy when new options constantly arise. Despite the development of new communication mediums and channels, such as social mediums, the traditional communication medias still remain available.

In this diploma work we present the results from a study of how adult immigrants utilise the services provided by the public library in Biskopsgården, Gothenburg. A survey encompassing 51 library visitors of foreign origin and an interview with two librarians at the library were performed.The results from the survey show that the majority of the informants were male students inages from 26 to 45 years and that they had been living in Sweden for a maximum of five years. 73% of the informants used the library to borrow literature in Swedish, 53% to read newspapers and periodicals in their native language, 43% to borrow literature in their native language and 43% to read newspapers and periodicals in Swedish.These results were compared with two other related studies with which partial correspondencewas found. In addition, related topics such as multicultural librarianship and the psychological aspects of immigration are discussed..

My essay is concerned with intercultural leadership and practical knowledge. The essay is about ethical dilemmas and the diversity of issues we face constantly at the preschool. In my story I examine the different views of knowledge and the opportunities to lead people in an intercultural way, and how they relate to each other. I start by looking at the ethical ideas that form the basis for our actions and our view of knowledge. Then, I examine how the practical wisdom guides the ethical dilemmas that arise at the preschool.

In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite. The aim of the study is to interpret the history of the forest in the area, i. e.

The purpose of this paper is to examine whether, and if so, how tourism effect the construction of a new city district with a stadium in focus. The study is based on a case study of Swedbank Arena and Arenastaden as nearby area. There has been an interest from the writers to study Swedbank Arena and Arenastaden, as it is a current subject, and both of them are under construction, which means that it was possible to see how the process works from the ground up. It has been shown that Swedbank Arena is built up in an entirely new district in which there will be new infrastructure that is tailored to the stadium and the crowd it?s expected to attract.

Girls in honour cultures have been the subject of many studies and are often debated in the media. The purpose with this study was to focus on boys in honour cultures. I wanted to understand the situation of boys in honour cultures with a perspective of the rights of children. My central questions were: How is it to be a boy in honour cultures? Are boys in honour cultures exposed? How are they exposed? My study was a qualitative study in which I interviewed four professionals who meet boys in honour cultures in their work.

The aim of this study is to examine the understanding, preschool teachers, have about their work related to energy conversion in the human body. Through individual interviews, answers have been sought to the following questions: What do the preschool teachers believe they need to know about the link between food and energy? What are the different methods preschool teachers use to workwith the area of energy conversion in the human body?The results show that preschool teachers have knowledge in terms of food and its nutrients as an energy source for the body to cope with. However the more thorough and detailed questions become all the more uncertainty there is about the topic. Preschool teachers on their own initiative do bring up the topic with the children and begin conversations as well as ask questions, perform experiments and demonstrations.

The city of Kalmar has a desire that their 3D maps of the city should come to a greater use and get residents more involved in Kalmar city. The purpose of this report is to show one way to work with these 3D maps when it comes to presenting information about Kalmar for its residents and tourists in a specific area.  The report also includes information about advantages and disadvantages with the use of 2D and 3D maps in different environments. Various reports and other sources indicate an interest in 3D and a use for this, but even that 2D is still seen as a natural way to read a map. By collecting information from relevant literature, interviews and user testing, the group has obtained sufficient background information to present the results of a web site, where the visitor can navigate in both 2D and 3D in a specific area of Kalmar. User tests and surveys have been conducted in two rounds and the web site has been revised after their results..

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Syftet med studien var att utvärdera vad tidigare klienter på Lenagården HVB, ett behandlingshem för vuxna med psykiska problem, upplevde som värdefullt, respektive vad de upplevde som negativt eller saknade i sin behandling. Utvärderingsfrågorna utgick från Lenagårdens programteori samt aspekter som tidigare forskning kring institutionsbehandling pekat ut som viktiga för framgångsrik behandling. Data samlades in via kvalitativa intervjuer med fyra tidigare klienter. Systemteorin har använts som utgångspunkt för resultaatanalysen.Utvärderingen visar bland annat att gott bemötande i termer av vänlighet och respekt samt personalens kompetens ansågs vara värdefulla faktorer i behandlingen. Själva terapin och behandlingsmetoden ansågs av samtliga intervjupersoner vara givande.

In today?s larger companies internal auditing is a common concept. For about twenty years ago companies? use of internal auditing took a turn from having been something popular to becoming more notorious. In this thesis we examine what might have caused that turn, We do this by looking at the vision and way of working for about twenty years ago and how the view of the area is today.

Storm water is defined as runoff from precipitation such as rain or snow. It is collected in sewage disposal systems and since it mainly originates from urban areas it can contain high levels of heavy metals, nutrients and oil etc. Polluted storm water is currently treated by different methods such as wet ponds, constructed wetlands and filter strips. This study investigates these methods, which in earlier studies have shown to give varying results regarding their treatment efficiency.This thesis has been written on commission of SWECO VIAK and was aimed at studying those parameters that may affect the treatment efficiency of nutrients and heavy metals in storm water treatment facilities (STF:s). Through literature studies the dominating treatment processes in ponds and wetlands were examined.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.
