Hälsosam vikt på sikt
Background: First Line Managers are expected to create a health promoting work environment. Research has shown that the prerequisites for accomplishing a health promoting leadership are not always the best. Aim: The aim was to elucidate the prerequisites for a health promoting leadership as First Line Manager at a University hospital in Sweden based on competence, role, support structures and own durability. Results: First Line Managers at the chosen hospital seems to have rather good conditions for conducting a health promoting leadership. All respondents did have a university degree and most thought that their competence corresponded well with the role.
Kartläggning av fallriskfaktorer för äldre i ordinärt boende inom landstingen Västmanland och Uppsala län (underlag för intervention)
AbstractObjective: To investigate the occurrence of and the risk factors for falls and to investigate level of fall-related self-efficacy and health-related quality of life in people living in community living, 75 years or older within Uppsala and Västmanlands county. A further aim was to identify predictive risk factors for falls. Design: A cross-section study with a descriptive, comparative and correlative design based on a questionnaire was used. Participants: The participants were recruited from Uppsala and Västmanlands county. A random selection on 525 individuals was done, from a population based sample, in the detailed municipalities.
Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering
Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
Physiological (heart rate and cortisol concentration in saliva) and behavioural responses in horses to four reactivity tests compared to the trainer's opinion about the horses? temperament
When performing studies that test the reactions of horses in different situations, important information
may be available about the horse?s reactivity level. With information from these tests, accidents and
dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological
parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.
Structure and tree diversity of lowland limestone forest on Seram Island, Indonesia
There have previously been very few studies of forests on Seram Island in the Eastern Indonesian archipelago and none before on lowland limestone primary forests. The COLUPSIA project on collaborative land use planning has therefore chosen Seram as one of two project sites. The objective of the COLUPSIA project is to establish collaborative and equitable land use planning. In order to achieve its objective the COLUPSIA project aims to improve understanding of traditional resource management and how it interacts with governmental systems, as well as enhancing knowledge about tropical landscapes and ecosystem services.The aim of this study was to contribute to the COLUPSIA project through describing lowland limestone forest on Seram Island in respect to (1) forest structure, (2) tree species richness and (3) tree species composition. We set up 5 plots, each of 0.2 ha, at one site, Mawalai, and collected data on tree variables (tree diameter ?10 cm) as well as for some other life forms and environmental data.
Vätskepreferenser hos unga kalvar
Den vanligast förekommande sjukdomen hos unga kalvar med infektiös orsak i Sverige är diarré. Enterit kan leda till uttorkning, acidos, rubbningar i elektrolytbalansen och i värsta fall dödsfall. Snabbt insatt behandling är avgörande. Till kalvar med fungerande digestionssystem rekommenderas i första hand behandling med oral vätsketerapi. Endast lite forskning har utförts om hur kalvar helst dricker sitt vatten.
Utbildning i våld i nära relationer. En kvantitativ studie om betydelsen av personalutbildning för att främja det preventiva arbetet.
Background: Intimate partner violence (IPV) is a large public health problem that foremost affects both women and children, nationally and globally. Several accessible reports about IPV and education for staff that in their occupation can meet battered people shows the importance of increased education for several occupational groups to decrease the large number of unrecorded cases.Purpose: The study explored how six occupational groups, in the municipality of Kungälv, related to IPV in their professions, were influenced by whether they had education in IPV or not.Method: We chose a quantitative approach, a cross sectional study. A questionnaire was constructed and handed out to 156 participations. The occupational groups were a section in a hospital, the police, the home care services, an elementary school, a pre-school and the public dental care. The answer frequency was 86 %.

Effect of plant maturity at harvest of haylage on digestibility and faecal particle size in horses fed forage-dominated diets
Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.
Development of real-time RT-PCR for the detection of human sapovirus in foods
Food-poisoning is a major health problem and an estimated half a million Swedes are food-poisoned annually, with acute gastroenteritis as a consequence. One of the major causes of contaminated foods is related to food- and waterborne viruses. To be able to trace back the source of contaminant, the method of detecting viruses must be specific and sensitive. No standardized method for detecting foods for sapovirus exists today.
The aim of the work described in this bachelor thesis is to implement and opti-mize a real-time RT-PCR method for the detection of all genogroups of human sapovirus in foods.
Nedfästning av oljemåleri på puts.En fallstudie från salongen på Mostorps slott i Halland
This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.
Forage production and summer use by ungulates on game fields and surrounding areas
Ungulates are causing conflicts between stakeholders due to browsing damage on forests and agricultural crops. At the same time there is a big demand of keeping high ungulate densities for sports hunting and recreational purposes. Movement patterns of ungulates are strongly correlated with forage availability. Therefore, measures affecting forage quantity and distribution might be a tool to reduce the economical losses in forestry without decreasing the ungulate densities and thereby decrease the conflict between different interest groups.This study investigated the potential biomass production and utilisation of marrow-stem kale (Brassica oleracea var. medullosa), at game fields in Misterhult, Sweden, as well as browsing effects on adjacent forests.
Ett holländskt fenomen i Värmland : Faktorer bakom och effekter av en holländsk inflyttning
AbstractDuring the last five years there has been a considerable immigration from the Netherlands to Värmland in Sweden. INVA, Invest in Värmland, wanted to highlight this phenomenon and therefore contacted Karlstad University to make a survey about how extensive the immigration is and what consequences it brings for the business life and municipalities in Värmland. We were luckily chosen to perform this research and the main focus in this study has been the following questions:? Why do the Dutchmen choose to buy their house in Värmland?? What are the main reasons for leaving the Netherlands?? What consequences does the immigration cause for the business life in Värmland?? How do the Dutchmen experience the contact with Swedish authorities?To answer the questions we designed a questionnaire that was sent to 200 Dutch house purchasers. The ambition was to survey all the Dutch house purchasers in Värmland, but with the time constrains and the municipalities having problem to find complete data, we limited the survey to 200 households.
Undersökning av förekomst av okända virus hos svenska fjällrävar med encefalit :
The artic fox is under threat of extermination in Europe. The population decreased strongly at the beginning of the twentieth century because of intensive hunting. The artic fox was placed under protection by law 1928 in Sweden but despite this the population has had difficultly to recover. This can depend on several reasons, but the main threats are shortage of food and competition from the red fox. Along with Norway and Finland, Sweden has carried out a project called SEFALO (Saving the Endangered Fennoscandian Alopex lagopus), whose objectives were to prevent continued decreased populationnumbers and through, for example supplementary feeding, help the population to recover.
Nord Pools systempris - en studie av prispåverkande faktorer
The intention of this thesis is, from a basic statistical viewpoint, to capture the relationship between the price of electricity and a sample of factors influencing the price. The thesis also aims at investigating whether knowledge about the relationship is useful when investing on Nord Pool. Tested factors are temperature, import, price of emission rights as well as a number of hydrological factors. The investigated period stretches from year 2000 until week 32 year 2007. The relevance of each factor was also evaluated yearly as well as for shorter periods in order to get a more comprehensive view of the relationship.
