Debuten av gluten ? Har tidpunkt för glutenintroduktion någon betydelse för risken att utveckla celiaki hos högriskbarn?
AbstractTitle: The debut of gluten ? Does timing of gluten introduction affect the risk ofceliac disease in high-risk children?Author: Sandra Hagwall Frohm and Maria IngmarSupervisor: Frode SlindeExaminer: Mette AxelsenProgramme: Programme in dietetics, 180/240 ECTSType of paper: Bachelor?s thesis in clinical nutrition, 15 hpDate: May 26, 2015Background: Celiac disease is a chronic disease in which the intestinal mucosa is damaged bygluten exposure, and the only treatment is a lifelong gluten-free diet. The disease affects about1 % of the population worldwide, but the majority are undiagnosed. Ingestion of gluten and thegenotype HLA-DQ2/8 are required for disease development, although additional genetic andenvironmental factors are believed to be of importance. One hypothesis is that timing of glutenintroduction in infants affects the disease risk.
Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils.
The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after direct seeding and planting. The study also attempts to simulate growth until first thinning.
Björnkram eller björntjänst? Möjligheter för personer med neuropsykiatriska funktionshinder att känna och uttrycka inflytande i insatser med avsikt att bidra till deras delaktighet i samhället.
In Sweden there are laws and recommendations from The National Board of Health and Welfare about the importance of a user's involvement in and possibility of influencing services directed at them. Even with such good intentions the same board reports that it is hard to know if people experience that they do. The purpose of my study was to examine how professionals can use their knowledge to help users increase their sense of influence in services that they use. My focus has been on adults with neuropsychiatric disabilities within the autistic spectra, such as Asperger syndrome, and on the professionals working with them. The specific problem among people with neuropsychiatric disabilities is a lack of social skills.
Bomullens nya ansikte ? Kan man finna ett material som kan agera substitut till bomullen för producenter inom yrkeskläder?
Syftet med undersökningen är att undersöka, beskriva och analysera kring hur vida det finns ett bra substitut till bomull. Undersökningen kommer att belysa hur marknaden ser ut i dag och vilka material som används. Vidare utreds parametrarna funktion, kundnytta och hållbarhet, som kan komma att spela roll i valet av material för producenter av yrkeskläder. I dagsläget finns det inget solklart val av material som skulle kunna mäta sig med bomullen gällande de parametrarna som uppsatsen tar upp. Vad man väljer att använda istället för bomull beror mycket på hur företagen väljer att fokusera gällande just funktion, kundnytta och hållbarhet.
Trimning av lead och lag filter
The work describes the development of an adjustment algorithm that will replace today?s manual adjustment of Lead- and Lag-filters at ABB Robotics industrial robots. The adjustment is mainly for the filter parameters in the control system.Three different algorithms have been created to replace the manual adjustment. One of them is based on the criterion from the manual adjustment and another one on optimization of the sensitivity function. The last one is a combination of the two.The report describe the development of the algorithms and how they behave during simulations and tests on real robots.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
Val av byggproduktionsmetod/ Praktikfall Klammerdamm : Golvgips eller avjämningsmassa
This report is about how to decide which method is the most suitable as floor covering at projectKlammerdamm in the centre of Halmstad. The covering has to be fire resistant and soundproof inorder to protect the wood structure and stop noise from traveling between apartments. There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long truck has nopossibility to reach the site. The construction site is small and the storage area is limited.
Implementering av Patientsimulator för Anestesimaskiner
In order to facilitate testing of anesthesia machines a patient simulator has been required by Maquet Critical Care AB. A patient simulator has been developed to reduce expensive and time consuming animal experiments and temporary lab arrangements. The patient simulator has been developed and designed to simulate human lungs with regards to anesthetic uptake, production of carbon dioxide and heating and moisturizing exhaled air.The system comprises a container and a test lung to simulate the volume and the dynamic of the human lung. The simulation of uptake of anesthetics has been implemented by pumping a fraction of the gas from the container through a bypass circuit with an active charcoal filter that adsorbs volatile anesthetics. The flow through the bypass circuit is generated by a pump and is controlled by a linear valve.The resulting performance of the patient simulator has fulfilled the requirements.
Från pre-human till post-human : Embryots reproduktiva status i skärningspunkten mellan stat och medicin
The aim of the thesis is twofold: the first aim is to identify a number of reproductive logics that are used to construct Swedish regulation of embryo donation for reproductive use as either ethical or unethical in the governmental ? and medical discussions ? and to examine how these logics are interconnected with notions of gender and parenthood. The second aim is to identify a number of tensions that arise in the application of the governmental ethical logic on the embryo and embryo donation and discuss how these tensions can be solved with a feminist material approach. I argue that the terminology used to distinguish between genetic, biological, social and legal parenthood in my material is insufficient for understanding the value of the embryo outside its pre-human status. I therefore argue for an embryonic feminist bioethics that is attentive to the embryos post-human status, and for a reformulation of the parenthood terminology in line with what I call ?reproductive ties?..
Livscykelanalys av flerbostadshus ? energieffektiviseringsåtgärder för minskade koldioxidutsläpp
The importance of energy- and environmental issues has increased, and the work towards reducing carbon dioxide emissions plays a major part. The European Union has set up goals for the membership countries to work towards this to happen. The carbon dioxide emissions in Sweden have been reduced the last few years, but there is still a lot to do. About 30 per cent of Sweden?s carbon dioxide emissions generate from energy usage related to housing, this is why the housing sector is of interest to examine.
Androstenons fysiologiska roll hos grisar
It is mainly high levels of androstenone and skatole in adipose tissue that is the reason behind boar-taint, which is an unpleasant odor and taste from the meat of adult male boars. The purpose of this literature study is to provide an overview of current knowledge about the physioloical functioning of androstenone. There are several studies showing androstenone´s function as a pheromone, and that it is an important part of communication and mating behavior between pigs. Androstenone is produced in the testes of the boar and transported via the bloodstream to the salivary glands where it is excreted with the saliva. Sows sense the pheromone, not via the vomeronasal organ as previously considered, but via the olfactory mucosa.
Effects of shade on milk production in Swedish dairy cows on pasture
Heat stress negatively influences the performance of dairy cattle such as lactation and reproduction. Heat stress can cause production losses as well as welfare problems. Years of research have shown that heat stress is a huge problem for dairy cattle in both the tropics and temperate zones but no such research have so far been done in northern European countries. It seems like shade is an important tool when improving pasture conditions and therefore
deserves more attention. The aim with this study was to investigate whether there is a need of providing shade for grazing dairy cows during the summer in Sweden.
Two groups of lactating Swedish Red dairy cows (n=15 per group) were kept on pasture.

Långtidsuppföljning och artrosutveckling hos hundar kirurgiskt behandlade för ruptur av kraniala korsbandet :
The high incidence of cranial cruciate ligament injury in dogs results in both
suffering and significant costs due to treatment and care of affected dogs. Today
there are several different technics for surgical treatment in dogs with ruptured
cranial cruciate ligament. At University Animal Hospital (UDS), SLU, in Uppsala
two fundamentally different methods; TPLO (Tibial Plateau Leveling Osteotomy)
and external fixation with suture material are practiced.
The aim of this study was to estimate if the different surgery technics result in any
difference regarding the function of the dog in a long term perspective. Since
motion and function are very affected by arthritis, was the purpose also to
determine if there are any differences in developing arthritis between dogs
surgical treated with external fixation respectively with TPLO. Development of
arthritis is common after surgery or traumatic injuries in a joint, such as cruciate
ligament rupture.
Unfortunately was the number of dogs in the study to small to achieve two
comparable groups.
Islandshästar med hosta och/eller prestationsnedsättning : skiljer de sig åt jämfört med andra raser?
The purpose of the study was to investigate whether or not Icelandic horses are
less severely affected in clinical symptoms of cough or decreased performance
than other breeds of horses. A breed variation in chronic respiratory disease
severity was suspected based on clinical experience at the Institution for surgery &
medicine, large animal, SLU Uppsala. A retrospective journal study of 17
Icelandic horses and 17 Swedish Standardbred horses with chronic problems with
cough and/or decreased performance compared several measurements of disease
severity.
The clinical signs, physical examination and laboratory testing results compared
were respiratory rate, abdominal breathing, lung auscultation, endoscopy results,
broncho-alveolar lavage (BAL) results and the blood gases pO2 and pCO2. All
parameters were available for all 34 individuals except for the blood gases, which
were analysed, in only four Icelandic horses and four Swedish Standardbred
horses.
The only parameters that appeared different between the two groups were
respiratory rate and pO2. The four Icelandic horses, which had blood gases
analysed, had more severe hypoxemia.
