Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Arkitektkontoret Sweco Architects i Göteborg har tagit fram ett förslag för ett bostadsområde i Varberg, där Varbergs kommun var beställare. De föreslog att ett eget områdesförslag skulle tas fram i Revit Architecture utifrån de planbestämmelser som gäller i området. Som en fördjupning i detta arbete valdes att även studera arbetsprocessen i programmet samt hur denna process kan tidsoptimeras. Ett problem idag är att en sådan process kan vara tidskrävande och ineffektiv. Syftet med detta arbete var att finna idéer på hur processen kan effektiviseras och att utveckla kunskaperna om Revit.Som en inledning modellerades hur området ser ut idag i Revit utifrån en ritning skapad i AutoCAD.

Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.

The aim of this study is to examine how one can understand the experiences that social workers within the social service's have of children who have committed sexual assault against other children, and the social workers? thoughts about the choice of actions and the family involvement in those actions. The study has a qualitative character. Information was obtained through interviews with social workers within two Swedish counties, and the analysis of the results was based on earlier research findings as well as theoretical aspects, such as systemic theory and salutogenesis.Regarding the actions taken for the target group, the social workers have, in many ways, a systemic perspective as they emphasize elements within the child as well as within the family. It is also shown that the collaboration with other authorities affects the choice of actions, and that it is important to involve the entire family in any interventions, so that the effect of those interventions may last over time.

In Sweden and in the rest of the world we face the problem how to create a sustainable development. At the same time the Swedish million program, a housing program made in the 1960:s and 1970:s, is facing a renewal due to lack of maintenance during many years. An attempt to join these two interests has been made in the residential area of Gårdsten north of Gothenburg. This paper is a case study to review the project and its approach to the sustainability concept. The purpose is to spread knowledge about the problems that can arise. By studying documentation about the reconstruction I have analyzed the approach that has been used. The housing company?s starting point was user participation and an intention to make the changes visible.

Energy losses are an essential part of a power grid company?s costs. From anenvironmental and economic perspective, it is important to reduce these costs. Toknow where efforts should be deployed, it is important to have good knowledge ofwhere in the network losses are situated. When creating network tariffs, there is alsonecessary to have a correct distribution such that the network customers that use acertain part of the network, only pays for the network losses in this area.

This paper constitutes graduate work at the Depart-ment of Urban and Rural Development at the Swedish University of Agricultural Sciences. In this paper the urban structure of the million program suburb Husby in Stockholm is examined and what effect this structure has on social life in the area. The main objective of the study has been to, with the help of morphological analyses, examine how to create meeting places and make the Husby Park more accessiblefor the inhabitants in Husby. There has been a selection of analyses to ensure that Husby?s spatial relationship with surrounding suburbs as well as local spaces in the Husby Park is described.

Deciduous forests are, according to the National Environmental Quality Objectives, a priority area. Deciduous forests are rich in species and the occurrence of dead wood is an important factor for biodiversity. In order to identify valuable deciduous forests for bio-diversity, conservation needs good analyses and planning tools. Habitat models combined with geographic information systems can be used to study the spatial structure of suitable habitat. The Lesser spotted woodpecker (Dendrocopos minor) has been proposed as an indicator species for deciduous forests, since this species is highly specialized on insect larvae in dead wood and requires large areas of deciduous-rich environments. Many riparian forest with high species richness and high nature conservation values are found along the Ume river in Umeå municipality.

A large number of rivers in northern Sweden have hydropower developments that cause negative effects on both up- and downstream migrations of anadromous species like Atlantic salmon. So far, most attention has focused on the hindrances of adult fish during their upstream spawning migration. However, since turbines in power stations cause losses on downstream passing fish, the focus on negative effects on smolts has increased. The aim of this study was to compare three different causes of losses of salmon smolts passing downstream through a power station area in the flow-controlled River Åbyälven in northern Sweden.A total of 61 wild salmon smolts were caught and radio-tagged in the River Åbyälven during their downstream migration in June 2009. The salmon smolts were released at three locations, 1.1 km upstream from the power station, in the turbine intake and in the upper part of a fishway, acting both for up- and downstream fish passage.

The aim of the study was to through empirical studies interpret the relation between three partially investigated house foundations, on an abandoned farm in Langhammars on northern Fårö. This relation focused upon two main questions; the time of use and the spatial distribution of the archaeological finds.Trough comparative analysis two of these houses can establish to have been contemporary, the third one is too roughly examined. A discussion about the hypothec idea of two or three contemporary farms was made with a negative result.In house 1 smaller processing of tools of flint has taken place near the fireplace in the larger room. A concentration of pottery was also visible near the fireplace, likely to be connected to cooking and eating. The smallest room in the northeast part of the house could have functioned as a storeroom and/or held workshop activities.The archaeological finds and the distribution of it, strongly indicates that house 1 mostlikely consisted of a dwelling house and house 2 functioned as a workshop; linked to activities with handicrafts.

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

The purpose of this study was to investigate produced laser data from the new national height model's airborne laser scanning in Sweden, what quality it has and whether it can be used for forest management planning. From airborne laser scanning one can obtain information on forest variables such as tree species, height, diameter and basal area. Norra skogsägarna is the principal employer of this project and they wanted know to the quality of the laser data which needs to cope with their standards. If the laser data the quality required it can replace some of the operations performed by field planners. To examine the quality of the produced laser data a control tax assessment has been performed in 30 forest departments. This was done in an objective manner.

This study aims to examine young peoples? attitudes towards crimes related to riots. It also examines if there?s a difference in attitudes to different crimes and if there is a connection between these attitudes and friends experience of crime, gender, socioeconomic position or residential area. There is a lack of research in this area, most of the studies on riots focus on the reasons and driving forces leading to riots.
