Increased understanding of the mechanisms that operate in conjunction with the welding of metal surfaces may help to improve existing manufacturing processes, and to enable new products and combinations of materials. The purpose of the project has therefore been to acquire a deeper understanding of what is happening in the bond for steel and for the factors that form the basis for a bond to develop between metals in the production of laminates by pressing. The merge has been done by pressing and the surfaces after the experiments have been studied in detail in the scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and with interferenceprofilometry in Wyko, to provide a greater understanding of the mechanisms that influence the bonding in the interface between metals. The project was limited to contain the materials Docol 1000, HyTens 1200, Aluminum AA3003 and a commercial steel. The parameters varied in the experiments to study their influence closer are temperature, pressure, heat treatment and pretreatment. This has been implemented by pressing with varying temperature and pressure.

Trycksår kan medföra fysiska och psykiska komplikationer hos den drabbade.

In search of Umbilicaria subglabra In Sweden Umbilicaria subglabra has its only known occurrence in Lybergsgnupens nature reserve in the county of Dalarna where it has been found only once in 1936. It was found on the east-facing rock spur, approximately 650 meters above sea-level. The lichen is now red-listed as Regionally Extinct (RE) in Sweden. The aim of this study was find U. subglabra.

Hemoplus® (Sarstedt, Nümbrecht, Tyskland) is a guaiac-based fecal occult blood test developed for human medicine. Guaiac-based tests make use of the pseudoperoxidase activity of hemoglobin so the test is not specific for human hemoglobin and can therefore be used in veterinary medicine. Peroxidase-containing foods such as meat (hemoglobin and myoglobin) can cause false-positive results of the test. To ensure that a positive result is not caused by diet, it has been suggested that canine patients should be fed a meatless diet for a few days prior to fecal occult blood testing. The aim of this study was to evaluate the effect of commercial dog food on guaiac-based tests. In this study fecal samples from healthy dogs were analyzed with Hemoplus®.

Sweden has been a member of the European Union since 1995 and the power of the organisation to make decisions has increased over the years in a rate which hasn?t been followed by an equally increase in democratization. This is partly due to the lack of participation in the decision making process and at the national level the citizens don?t possess enough channels to compensate the loss of influence. To solve this democratic dilemma, more and more countries are turning to the referendum.

Bakgrund: En kombination av olika riskfaktorer och ett yttre tryck bidrar till att patienter drabbas av trycksår. Sjuksköterskor i samarbete med undersköterskor ansvarar för att förhindra risken för trycksår hos patienter. Tidigare studie påvisar att femton procent av inneliggande patienter på sjukhus drabbas av trycksår. Syfte: Syftet med studien är att belysa varför patienter får trycksår trots att sjuksköterskan i samarbete med undersköterskan bör ha kunskaper för att förebygga vårdrelaterade trycksår. Metod: Författarna använder sig av metoden allmän litteraturöversikt.

Syftet med denna litteraturstudie var att undersöka om nutritionstillskott, tryckavlastning och typ av förband har någon påvisad effekt på läkningen av trycksår. Litteraturstudien grundar sig på Goodmans systematiska tillvägagångssätt. Litteratursökningen gjordes i CINAHL, PubMed och The Cochrane Library samt att artiklar som inte var tillgängliga i fulltext via någon av databaserna söktes via Samsök. Granskning och kvalitetsbedömning av artiklarna gjordes individuellt utav författarna oberoende av varandra utefter ett modifierat granskningsprotokoll. Elva artiklar av varierande kvalitet inkluderades i litteraturstudien.

Vattenfall Heat Uppsala runs the waste incineration plant in Uppsala, which produces district heating, process steam, district cooling and electricity. Vattenfall Heat Uppsala has decided to introduce an energy management system with the aim to increase the energy efficiency of the plant. The basis in such a system is to make an energy mapping.In this thesis an energy mapping has been performed at the waste incineration plant with the aim to identify and determine the size of energy flows. The investigated energy flows are used fuel, produced and used steam, produced district heating and cooling. Also the use of electricity to run the processes has been investigated.

This article starts with a review of the literature regarding the normal reproductive physiology of the mare, normal luteolysis, different causes of prolonged luteal phase and theories behind these. The article also presents a study where it was examined if treatment with human choriongonadotropic hormone (hCG) during the luteal phase induces prolonged luteal phase in mares, thus preventing estrus. The study consisted of two parts: one intensive study of eight mares at the former Department of Obstetrics and Gynaecology at SLU, Uppsala, Sweden and one field study of seven mares at a stud farm 70 km north of Uppsala. The mares in the intensive study were divided in two groups: one with four mares that were injected with hCG in luteal phase when they had a follicle of minimum 30 mm and a second group with four mares that were injected with sodium chloride at the same time. These mares were examined with ultrasonography and blood samples.

Syftet med denna litteraturstudie var att beskriva hur sjuksköterskor arbetar med preventiva åtgärder vid trycksårs uppkomst samt vilka omvårdnadsåtgärder som ges till patienter som utvecklat trycksår. Vetenskapliga artiklar söktes i databaserna Medline via Pubmed och Cinahl med sökorden nursing, pressure ulcer, prevention, treatment, therapy, intervention. Endast artiklar från år 2003- mars 2008 användes i studien. Både kvantitativa och kvalitativa artiklar användes, dessa artiklar granskades utifrån två modifierade granskningsprotokoll. Resultatet påvisade variationer av dessa preventiva insatser som sjuksköterskor använde sig av.

In the assembly process of airframe structures there are many drilled holes and on some parts the holes are mainly drilled manually with pneumatic handheld drilling machines. During conventional drilling in metal, burrs appear. To remove these burrs the parts of the structure must be separated and deburred before they can be put together for fastening. This is a time consuming measure and therefore expensive. To facilitate this process and lower production costs some parts of the process needs to be automated.A part of this thesis was a project in co-operation with Saab, Novator, Specma Automation and the University of Linköping.

Hemoglobin is built up from protein and heme groups which give the blood its red colour . Hemoglobin transports oxygen and carbon dioxide between the lungs and other tissues in the body. Normally, a piglet has a hemoglobin value of 130-150 gram per liter blood, and the lower limit before anaemia appears is 80 grams per liter blood. The immune defense is also dependent upon the presence of iron in hemoglobin, since iron participates in different enzyme systems. When the piglet develops anaemia, it becomes pale and thicker around the neck.

ABSTRACT. Introduction: Human Immunodeficiency Virus (HIV) is a retrovirus which occurs worldwide and spreads between humans mainly through sex, from mother to child, blood and blood products and between injecting drug users. After been infected with HIV for a couple of years the final stage of the infection progress into Acquired Immune Deficiency Syndrome (AIDS), and there is no cure or vaccine, only medication that delays the development of the disease. Objective: The aim of this thesis is to examine the preventive work against HIV in Sweden, the groups at risk for getting infected and to highlight sexual attitudes and behaviours among adolescents and young adults. Method: A literature based study method was used and the material is based on scientific articles and reports from active actors within the field of HIV prevention.

AbstractUppsatsen handlar om tv-spelen Hitman: Blood Money (2006) och Hitman: Absolution (2012) samt dess adaptionsförhållanden till filmtolkningen Hitman (2007). Spelen är utvecklade av det danska spelföretaget IO Interactive och filmen är regisserad av den franska regissören Xavier Gens. Analysen är baserad på åtta teoretiska texter varav en text handlar om tv-spel och dess förhållande till film, fyra texter om adaption (varav två närmare går in på auteurteorier), en text om våld, en text om skräck och slutligen en text om genreteori. Uppsatsen tar upp problematiken i adaptionsprocessen med fokus på överföring från spel till film och sedan vice versa.Den tar också upp tre fördjupningsämnen som är anpassade till spelen och filmen samt ett mindre fördjupningsämne om vem som har rätt till att kalla sig auteur. Dessa tre primära fördjupningsämnen är skräck, våld och genre.

Today most dosages used in horse medicine are based on studies in adult horses. Since there are differences between adult and neonatal horses with respect to different pharmacological parameters this can cause problems when administring drugs to neonatal foals. Neonatal sepsis is a common cause of morbidity and mortality in foals and aggressive antibiotic treatment is needed immediately when sepsis is suspected. In Sweden the combination of trimethoprim/sulphadiazine and bensylpenicillin is often used as the initial treatment. When administering drugs, interactions can occur between the drugs and endogenous substances.
