ABSTRACTBackground: To be stricken with a cardiac infarction is among other things linked to different risk factors.  Many studies show that the participants in cardiac rehabilitation programs learn to deal with the risk factors, increase their quality of life and lessen the risk for re-infarction.Objective: To describe the lifestyle and perceived quality of life of the individuals after having participated in cardiac rehabilitation program and to see if they had maintained their results up to a year after having a cardiac infarction.Method: The 19 individuals who had participated in cardiac rehabilitation in 2010 after having had a cardiac infarction were asked to participate in the study. Everyone agreed to participate. The study was made analyzing the surveys, one a locally made, that the individuals had filled out four and eight months after cardiac infarction, and the other the generic Quality of life questionnaire EQ-5D, that the individuals had filled out two and twelve months after cardiac infarction. Result: The individuals have not changed their lifestyle after having participated in cardiac rehabilitation which can be interpreted that they have followed existing recommendations. The mean weight increased with one kilogram, no depression is shown and they stress less.

The survival of hatchery reared smolts is generally low after release. To get a better understanding of what variables affecting migration success, Atlantic salmon smolts were studied during their out-migration in the old river channel in the lower part of river Umeälven. The area consists of shifting habitat and complex structures which causes difficulties for smolt on their migration out to sea. The aim of this study was to try to determine the effects of feed restriction, fin conditions and different physical barriers in the river, on the migratory behavior of Atlantic salmon smolts in the river Umeälven. The river was divided into six different sections using acoustic receivers strategically deployed along the river. Two-year old hatchery-reared smolts (n=150), in three different weight classes, were tagged with acoustic transmitters.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

AbstractA systematic replication study was conducted at the training site at the University of Karlstad. Student therapists performed cognitive-behavioural therapy (CBT) as a part of their master?s degree in psychology.  The systematic replication that took place was based on the work of Hiltunen et al. (2013), who evaluated the efficacy of CBT treatment conducted at the training site previously mentioned.

This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.

SyfteSnusandet har ökat de senaste åren, särskilt bland kvinnor och yngre personer och till flera samhällsgrupper. Rökning har under många år genomgått rigorös forskning och därigenom bevisats vara förenat med ohälsa. Däremot är forskning på snusanvändandets hälsoeffekter eftersatt. En fysiologisk effekt som föreslagits av långvarigt snusande är påverkan på balans (posturalt svaj). Uppsatsens huvudsyfte är att undersöka effekten på balans av ett långvarigt (sex veckor) uppehåll från snus i en grupp av dagligsnusare. MetodI studien genomförde dagligbrukare av snus (n=13) tester av posturalt svaj före och efter sex veckors uppehåll från snus.

Övervikt och fetma beror till stor del på ändrade levnadsvanor och är ett problem att ta på största allvar eftersom fetma kan leda till allvarliga följdsjukdomar och sänkt livskvalitet. Preventiva åtgärder är nödvändiga för att hindra den fortsatta fetmaepidemin och här kan sjuksköterskan fylla en viktig funktion som stödjare och rådgivare för obesa personer. Syftet är att beskriva vuxna obesa personers upplevelser och hantering av viktnedgång. Metoden som använts är litteraturbaserade studier av åtta kvalitativa artiklar. De obesa personernas upplevelser framkommer i tre teman. Upplevelser innan viktnedgång beskriver olika stadier som obesa personer genomgår innan de beslutar sig för viktnedgång samt beskriver även upplevelser av fördömande attityder.

The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity in biosorbing heavy metals.

The aim of this study was to compare activity, lying down and getting up behaviour, weight gain and cleanliness in heifers in cubicles versus on deep-litter. The study was conducted from autumn of 2005 until autumn of 2006 in a commercial organic dairy herd with 340 cows. In 2005 the farm rebuilt half of the young stock accommodation from deep-litter pens to cubicles. The experiment used 150 heifers of the breeds Swedish Red, Swedish Holstein and crossbreeds between these, all born on the farm. The animals were divided into three blocks based on breed and within each block they were sorted after increasing age. The youngest heifer in each block was randomly allocated to one of two groups, cubicle or deep-litter pen.

Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Vitamin D supplementation and its effect on body composition in the overweightand obese ? a systematic reviewAuthor: Johanna Blum and Emma Sellin FrimodigSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: There is an increasing burden of overweight and obesity worldwide. Theconditions lead to morbidity and lowered quality of life. Since there is research showing aconnection between obesity and low levels of serum 25(OH)D, this raises the question ifsupplementation of vitamin D may have positive effects on body weight, waist circumference andbody composition in the overweight and obese.Objective: To investigate if there is enough scientific evidence to recommend vitamin Dsupplementation combined with nutrition therapy to overweight and obese patients.Search strategy: The systematic collection of data was performed in the databases PubMed andScopus. Search terms included were ?vitamin D supplementation?, ?obesity? ?cohort?, ?vitamin D?,?vitamin D3 supplementation? and ?overweight?.Selection criteria: Human studies with RCT, CCT or cohort design written in English orSwedish were included.

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

In 2013 a new emission standard for heavy trucks was introduced and hence a number of new parts was brought in to Scania CV AB. This created a need for modifications in the silencers flow. The flow is highly complex involving several suppliers, call off methods and different models of silencers. The aim for this project was to improve the existing silencers flow. The flow, from supplier to assembling, has therefore been mapped.

The purpose of this report is to investigate the possibilities with drain water heat recovery (DWHR) in residential buildings. Information and relevant theory has been collected and summarized in this report. Calculations have been done for given scenarios to evaluate profits. DWHR heat exchangers use simple technology and have long life-time. The heat exchanger is connected to outgoing drainage pipe and incoming cold-water supply so countercurrent flow is accomplished.
