The housing estates in the outskirts of Sandviken, consist of relatively large scale apartment buildings. This report, that is a B.A. thesis at 10 Swedish university points, aims to investigate and describe the opportunities to improve safety and security for inhabitants in Norra Björksätra. The purpose with this report is to make Norra Björksätra to a more attractive place to live in, by changing the negative trends in the area. Since demolition of at least some of the houses could be of current interest in some years; the purpose is also to investigate whether demolition or renewal of the area is the best solution.

This thesis studies settlement continuity on Gotland between approximately AD 200 and AD 1700. The method used is to calculate correlation between the geographical distribution of all known Iron Age stone-wall-houses (on Gotland known as "kämpagravar") and all farms included in the detailed taxation maps from approximately 1700. The number of remaining house foundations is between 1800 and 1900. A model to estimate the number of removed foundations is presented. It is based on the assumption that the settlement density was proportional to land use around 1700, and that the rate of removal is related to the current land use.

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.

During an investigation of animal welfare in animal production, the focus has for a long time been focused on the absence of stress, suffering and injuries, and positive emotions have not been prioritized. However, in recent years that has been drastically changed. The public interest have increased for buying animal products from animals that have had a decent life, which have led to that play, exploratory behavior and other positive behaviours has come to play a significant role in welfare assessment. The welfare of cattle is difficult to assess since there is currently no ancestors to study, it is thus difficult to determine which behaviors can be regarded as natural and thus positively related, acordingly the welfare of cattle have been forgotten and research on positive emotions of cattle have not been prioritized. The aim of this study was to observe which behavior growing cattle performe, and if there was any differences of which kind of behavior that was observed, if the cattle is keept on slatted floor or on a deep straw bedding. Furthermore, antoher purpose was to investigate if the observed behaviours indicate a positive, negative or natural welfare, and if it is possible to use the observed behaviours in a welfare assessment.

The aim of this study was to investigate which elements that functioned in a positive way on the natural behaviors of dairy cattle among KRAV certificated and conventional farms. The study was based on reading of earlier research and completed by interviews with farmers, animal health inspectors and consumers. The results showed us that the KRAV certificated farms used only loose housing barns and that the cattle were allowed a pasturetime of five months, or more, in one year. Our interviews with the consumers confirmed that KRAV was a well known trademark. The conventional farms were more flexible in their choice of housing systems, and used both loose housing barns and barns with the cattle tethered.

In 1993, Sweden signed the Convention on Biological Diversity and thus agreed to conserve our indigenous biological diversity. As a part of the convention, Sweden is obliged to conserve a number of domestic animal breeds and among them the Linderöd pig. In 1952, the zoo, Skånes Djurpark, took care of a pregnant sow that was regarded to be related to the old "forest pig". The old forest pig was thought to have been extinguished by the early 20th century as a result of the ban on boars not approved by state inspectors. However, according to later accounts, several farmers still kept some of these non-approved pigs.

The Falun area has been undergoing mining activity for a very long time and miningslag piled up and was used as foundations for building houses and roads, Ingarvetstarted expanding in the 1970s to an industrial area. The main goal for this report is toreconstruct a soil map of how the landscape was before anthropogenic effects. With thehelp of ArcGIS and geotechnical reports a soil map for parts of Ingarvet, Falun werecreated..

This bachelor thesis aims at investigate how a specified house can optimize its energy consumption.Today the house often stands for the major part of the energy consumption in a consumers? life,whereas an energy optimization creates economic as well as environmental advantages. It is importantto make old houses more energy efficient, but putting high energy demands on new houses could beargued to be more important. The installations functions as both the heart and brain in a house, thusmaking it important to energy optimize these. Since the background describes the importance ofenergy efficiency and optimization in a house, the focus area of this report will be an investigation ofdifferent types of heating systems in order to be able to choose the one most suited for the house.Aspects considered when choosing the heating system was how economic the system is both inservice- and investment costs and how environmental and operational friendly the system is.Through literature reviews there were sufficient information gathered that served as a foundation whencomparing and choosing between the four systems - district heating, pellet-fired boiler, geothermalheating and solar heating.

I syfte att undersöka om, och i så fall hur, förskollärare arbetar med djuretik som en värderingsfråga undersöks (1) förskollärares tolkning av läroplanens skrivning om ?respekt för allt levande?, (2) hur förskollärare arbetar med värderingsfrågan djuretik och (3) vilken hänsyn de tar till läroplanens krav på saklighet och allsidighet i detta arbete. Empirin bygger på kvalitativa intervjuer med sex förskollärare varav 3 är vegetarianer. Analysen baseras på poststrukturalistisk teori och teori om den dolda läroplanen. Informanterna anger att de arbetar med djuretik i ringa omfattning men visar också att förskollärarna förmedlar omedvetna budskap om djuretik.

Dental implants that are integrated into the jaw bones are widely used to replace lost teeth in human beings. Tooth-loss is often related to loss of the surrounding alveolar bone. This can make implant placement difficult and a bone substituting material may be required. The standard method is to use a bone graft harvested from the patient which requires additional surgery than that needed for implant placement. Limitations in the amount of bone that can be harvested also pose a problem.

Soybean meal from South America is the most common protein feed used for animal production in Sweden. Production of soybean has negative effects on the environment and the transports from South America to Sweden causes considerable CO2 emissions. Therefore it is a growing interest in locally produced protein feed in Sweden. Protein feeds that are possible to grow in Sweden are rapeseed, peas, faba beans and lupins. Those are adapted to the Nordic climate and are perfect to grow in cereal rotations.
