Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Betydelsen av kön och sexualitet i mötet med sjukvårdsrådgivningen.
SammanfattningDetta är en studie av sjuksköterskors bemötande av patienter på Sjukvårdsrådgivningen i Region Skåne. Syftet är att undersöka hur det helhetstänkande som är vanligt förekommande i teoretiska debatter om sjukvården är förankrat i den praktiska verksamheten. Jag fokuserar på bemötande som kompetens, och studerar dess plats och auktoritet i organisationen. Jag undersöker även hur helhetstänkandet praktiskt fungerar i mötet mellan sjuksköterska och patient genom att fokusera på hur kön och sexualitet synliggörs och beaktas i samtalen.Jag utgår från Judith Butlers teori om den heterosexuella matrisen och om hur kön och sexualitet görs genom social interaktion. Jag använder mig också av intersektionalitet som ett analysverktyg.
Bibliometrisk kartläggning av det idrottspsykologiska fältet
Objectives: The aim in this thesis has been to generate information relevant for strategic positioning and future evaluations within the scientific field of sport and exercise psychology. This has been done by request, and in collaboration with The Group of Sport and Exercise Psychology at the Institution of Psychology at the University of Umeå.Research questions: (1) How does the cognitive structure within the field of sport and exercise psychology take shape with respect to research topics in current sport-psychological research, i.e. the research front? (2) How does the social structure within the field of sport and exercise psychology take shape with respect to formal scientific collaboration?Data: 879 articles published between 2008-2011 were used in this study. The population of articles were collected from a set of 5 core journals: International Journal of Sport Psychology, Journal of Applied Sport Psychology, Journal of Sport and Exercise Psychology, The Sport Psychologist, Psychology of Sport and Exercise.
Effekt av ACE-hämmare på incidens av hjärt-kärlsjukdom och mortalitet hos diabetiker typ 2 samt av diabetes hos hypertonipatienter.
Background: Diabetes mellitus is a chronic disease that manifests as an increased level of glucose in the blood. According to the World Health Organization (WHO), 347 million people have diabetes worldwide. In year 2004, 3.4 million people died from the consequences of high blood glucose. In the Swedish population the prevalence of diabetes is estimated to 3-4 %, out of which 85-90% are Type 2. Among senior citizens a prevalence of diabetes is seen in Sweden up to 14 - 15%.
Leder kastrering av hanhundar till bättre djurvälfärd?
Castration of dogs holds many reasons and opinions, therefore methods, traditions and rea-sons vary. The approaches have during time changed from mostly surgical castrations to also including hormonal treatments. Castration is used to control the dog's reproductive abilities, for medical reasons and to possibly rectify problems of behavioral nature. How common a particular method of castration is in a country is highly dependent on the country's traditions. In Sweden it is most common with castration for medical reasons, such as possible elimina-tion of diseases, for example, benign colorectal tumors.
Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :
Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse.
This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.
Effects of biogas residues on respiration and denitrification in arable soil : evaluation of methods, microbial activity and agronomic implications
Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.
Toxicitetsanalys med luminescenta bakterier: undersökning av yt- och grundvatten från Gällivare bangård
Examensarbetet har utförts på uppdrag av Banverket Norra banregionen. Syftet var dels att identifiera vilka föroreningar som finns på Gällivare bangård, dels att få en uppfattning om toxicitetstest, främst bioluminescenta test och att utföra en screening med vatten från Gällivare bangård med ett bioluminescent bakterietest. Försök gjordes även med en metallösning av koppar och PAH-förorenat vatten samt en blandning av koppar och PAH. EC50-värden efter 15 och 30 minuter har beräknats för de vattenprov där så varit möjligt. Vattnet från Gällivare bangård analyserades på laboratorium för att om möjligt kunna identifiera vilka eller vilket ämne som ger upphov till eventuell toxicitet.
