Att levandegöra historia : En undersökning om att använda Stockholms Stadsmuseums historia i historieundervisningen
The purpose of this paper has been to shed light on the ways the history represented at the City Museum of Stockholm can be used in education at the Gymnasia level. I have made use of the following set of questions to attain this purpose: 1) How is the City Museum's activity vis-á-vis the gymnasia organized and what is the purpose of this activity? 2) What positive results do the interviewees see in the collaboration between the schools and the Museum? 3) Why did the teachers represented in this paper choose to make use of the Museum in their education? The bulk of the study is based upon three interviews with the First Curator at the City Museum of Stockholm and two teachers, from Viola Gymnasiet and Skogsgårds Gymnasiet respectively. My method is qualitative and interpretative with hermeneutic features.In my interpretation of the source material I have made use of historian Klas-Göran Karlsson's classifications regarding the needs for various forms of history, use of history, users and functions of results. In this way I have been able to establish how the Museum and the teachers represented in the study make use of the history that is represented at the Museum.
Bremsningens effekter hos häst : utvärderat med hjälp av termografi, hormonanalyser och hematologi
Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.
Diabetes hos hund : utfodring, motion och vikt som möjliga predisponerande faktorer
This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.
Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark
In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease.
This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.
Cultivation of Chlorella vulgaris in nutrient solution from greenhouse tomato production : a possibility to reduce nutrient levels and produce commercially interesting metabolites
The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value.
Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.
Förebyggande effekter av fysisk aktivitet på depression : ? en litteraturstudie
Objective: To study the evidence on physical activity (PA) as an effective preventive strategy for depression.Methods: A search of electronic databases was performed for articles between 2007 and 2012, both original research and review articles, concerning the link between PA and depression on children, youth and adults. Three reviews, five longitudinal and two cross sectional studies were included.Results: PA reduced the likelihood of depression in many studies and a sedentary or inactive lifestyle increased the risks for mental health symptoms such as depression. One study showed that low PA in childhood increased the odds of depression as an adult and other studies on teenagers saw a connection and mediation between PA and self-esteem whereas physical fitness showed no mediating effect. Many of the studies and reviews point out the insecurity regarding the dose-response association and the difficulties in defining causality.Conclusion: PA might have a preventive effect on depression. Some evidence exist to support that PA in childhood prevents depression in adults.
Karlskrona stadsbibliotek 1906-1959 ? En bit av ett biblioteks historia
This master?s thesis will try to describe the beginning and development towards a modern public library of the town library in Karlskrona between 1906 and 1959. The specific years refers to the year the library was established and the year it moved to the new library building in the centre of Karlskrona. The aim of the thesis has been to do this historical description and to look at the course from the perspective of the national policies and development for the Swedish modern public library. The thesis is based mainly on reports of the proceedings of the public library and other biographical documents and literature, which has been found in two local archives.
Broiler production in Zambia - management, growth, diseases and welfare
Successful broiler production in hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare.
The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
Betydelsen av ämnet idrott och hälsa för att aktivera ungdomar på fritiden: en förebyggande åtgärd mot ohälsa
A large problem in our society is the diseases that inactivity brings to the population. The lifestyle you have in adolescence is often the same that you have in adulthood. Because of this, prevention should start in youth. The aim of this study was to investigate the experience that youths have of physical education and it?s influence in their spare-time activities.
Samband mellan en längre tillväxtsäsong och en ökad smoltstorlek i Vänerområdet
AbstractThe purpose of this study was to see if there is a connection between smolt length from Brattfors salmon cultivation and temperature. Climate changes are expected to give a higher temperature that could result in a longer growing season for the fish.Cultivated smolt is today bigger than it was before, it is also bigger than the wild salmon. The growth season of salmonids depend on the water temperature, salmonids need 6-80C to grow. Water temperature has been surveyd since the late 50´s in Brattfors. The result shows that it?s now considerable more days per year with higher temperature.
Pilotstudie av en ny metod för mätning avendotoxinaktiviteten i blodet hos tikar med pyometra
Förhöjda halter av endotoxin i blodet förekommer ofta vid sjukdomen pyometra hos tik och kan orsaka många av de allmänna symtom som ses vid sjukdomen. Endotoxin Activity Assay (EAA) är en ny, snabb metod för mätning av endotoxinaktivitet i helblod. EAA-metoden är anpassad för humanpatienter, men har testats i forskningsstudier och visats fungera även för hundar och efter viss modifiering också för hästar. Två olika apparaturer från finns att tillgå för EAA (från Spectral Diagnostics Incorporated). Den apparatur som utvärderas i den här studien har aldrig tidigare testats på djurslaget hund.

The cooking liquid is called white liquor.
Elastiska bibliotek : en undersökning av två folkbiblioteks formbarhet och gränser med hjälp av begreppet elasticitet
The purpose of this Master thesis is to examine whether the term elasticity is relevant and functional to apply to public library organisations. Another aim of the thesis is to relate the term elasticity to public library organisations in a network society. Sociologist Manuel Castells provide the theoretical framework on the network society. Three investigations (meant to complement each other) in two Swedish public libraries seek to give answers to these questions.To be able to examine which areas of public library activity are elastic, I make a rough definition of what public library organisations consist of ? nine activity fields are identified using IFLA?s guidelines in combination with Swedish law of public libraries.

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.
