I denna studie har prestationsa?ngest underso?kts i relation till tre olika typer av socialt sto?d och tva? faktorer inom tidspress. Tidigare forskning pekar pa? att socialt sto?d spelar en betydande roll fo?r minskad prestationsa?ngest i studier, samt att tidspress ger en o?kad effekt. Underso?kningen hade 151 manliga studenter fra?n tva? olika program pa? en ho?gskola.

 Conclusion:Medical treatment may have a role in platelet count after transfusion. Since the TACSI platelets passed the quality requirements, and the vast majority of patients platelet count increased after TACSI platelet transfusion, the TACSI platelets will replace the old method to produce platelets at the Uppsala University hospital.  Methods: A new approach that pools 8 buffy coats (TACSI platelets) that were separated into 2 units instead of 4-6 buffy coats pooled to 1 unit was investigated in this study. After the platelets were extracted from the buffy coats their quality was controlled and subsequently the platelet product was evaluated in 96 patients. Results: The results showed that 80 % of the platelet units passed the European quality requirements. Further, the platelet count was increased in most patients that received TACSI platelets. Conclusion: Medical treatment may have a role in platelet count after transfusion.

AbstractGlobalisation has lead to changes on many levels of our society; -industrial, technological, and corporate to name a few. This is an ongoing process which affects the society we live in today. The process is affecting the working-conditions for everyone through the changes of the relations on the working market. The unions have enjoyed a very special role in Sweden for a long time, but that role is now affected by these changes. The relationship between state and unions is changing, and the unions? influence in politics is decreasing.

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Malignant melanoma represents 4-7% of all canine neoplasms and they are the most common malignant tumors of the oral cavity and digits. These tumors are often aggressive and metastasize quickly. To date there is no effective treatment and survival times are short. Most dogs are euthanized due to complications caused by metastases. Melanin pigment is a hallmark of melanomas and is usually present in large amounts in these tumors.

Detta examensarbete behandlar friktionen hos fluida och solida smörjmedel, under höga, upp till 2,5GPa, transienta tryck. Friktionsstudier har gjorts i en befintlig ?Ball and Bar utrustning? vid Luleå tekniska universitet. Utifrån dessa studier har kurvor som representerar friktionskoefficienten som funktion av tiden för 15 oljor vid olika tryck och temperatur erhållits. Exempel av dessa finns inkluderade i rapporten.

Syftet med studien är att undersöka och skildra några studenters motiv, motivation och upplevelser kring högre studier. I bakgrunden ingår forskning kring studentidentiteter (Bron m. fl., 2013), men efter hand tillkommer andra begrepp och teorier som bidrar till att belysa undersökningsmaterialet. Studien är grundad på kvalitativ metod, med semistrukturerade intervjuer av sex studenter i åldrarna 25-30 år. Resultatet av de sex studenterna redovisas som personporträtt, där både likheter och skillnader mellan studenternas motiv, motivation och upplevelser i relation till högre studier framgår.

This work is a product development of a product which facilitates enduro drivers swallowing fluid while driving. My own experience of the problem and a custom survey gave me some frames and requirements of how such a product would look. To obtain the different concepts the method of brainstorming was used where I outlined the various proposals. The basic concept was that some kind of pump would build pressure in the liquid and when the user opens the nozzle the liquid will come out without the need to use the mouth to suck. The screening phase consisted of two steps.

Denna kandidatuppsats undersöker vilka upp­fattningar sjuksköterskor och homo­sexuella män har kring reglerna för blodgivning, med inriktning på att homosexuella män i praktiken inte får donera blod. Studien har genomförts med kvalitativ intervju som metod.Resultatet framhäver att mina informanter klassificerat blod och människor olika, där både utländskt blod och svenskt blod rangordnas efter potentiell risk för smitta. Sjuksköterskorna och de homosexuella männen hanterar även reglerna olika, där sjuksköterskorna lägger ett större fokus på att skydda de som ska få blodet. Samtidigt anser de i likhet med de homosexuella männen att reglerna är diskriminerande och bygger på fördomar om att homosexuella män skulle bete sig mer riskfyllt än andra i samband med smitta. Egentligen går det inte med säkerhet att veta om någon är ärlig när de besvarar hälsodeklarationen som ska hjälpa blodcentralen att sålla bort olämpliga donatorer.Bloddonation från homosexuella män går att se från olika håll och är därför ett komplext ämne utan ett lätt svar, då tekniken inte kan upptäcka smitta omedelbart från smittillfället.

This study has been made to evaluate if there is a significant difference between non-estral intact versus ovariohysterectomized queens in their production of estradiol after exogenous gonadotrophin-releasing hormone stimulation. The purpose is to find a tool, which can help to diagnose if a free-roaming queen is already ovariohysterectomized or not. There are also other situations where this tool could be useful, for example to diagnose the ovarian remnant syndrome. Previous studies in bitches have shown that GnRH-stimulation is an excellent tool to diagnose the presence of ovaries in the bitch. Eleven ovariohysterectomized and eleven intact queens have been included in this study where we have analyzed plasma estradiol and progesterone concentrations before and after a single intramuscular injection of the GnRH agonist buserelin (Receptal?).

Detta examensarbete på 22,5 hp har under våren 2007 genomförts av Annica Flödén, student vid Innovations- och designingenjörsprogrammet på Karlstads universitet på uppdrag av Claratappen.Under arbetet har en lösning på Claratappens problem med att plasmagivarna har svårt att ersätta den vätska de förlorar under tappningen med någon slags dryck tagits fram, då deras ostadiga bord gör att vattenmuggarna spills ut över dem.Detta gjordes genom att tillämpa designprocessen som vi under utbildningen lärt oss. Tonvikten under researchfasen lades på att observera hur det fungerar på Claratappen samt en enkät som sändes ut till andra blodcentraler runt om i landet. Utifrån det som framkom under researchfasen togs sedan några olika lösningar fram och en av dessa valdes ut för vidare utveckling.Den utvalda lösningen kom att bli ett avställningsbord, Huvudfoting, ett bord som fästs på britsens underrede där själva bordet kan vridas i fyra fasta lägen, bordet har också två hål för vattenmuggar så det kan delas av två olika givare. Den har även en bottenplatta som gör att den kan stå själv vid till exempel förvaring då den inte behövs. Fästet är konstruerat så att den kan fästas på båda sidor om britsen.

In this project a washing station has been constructed for Albany International AB. At present, there is no existing system to clean the dirty pipes that are coming back to the company.The work followed the product development process, and it started with the requirements list. This was followed by brainstorming, evaluation and completion.The result was a concept for de present time and one concept for the future.The present concept is intended to be built immediately. This is an adjustable bench with sliding bearings to facilitate the work. The actual cleaning is done with a high pressure washer that uses hot water.

AbstractThis essay concerns a qualitative case study seeking to understand six boys? reading habits and to investigate why it is that some boys who do not like reading nevertheless display good reading comprehension according to the results achieved for that skill in national tests. The study shows that the boys? perception of reading has a lot to do with the contact they have with books when they are small. Whether or not there are adult role models in the home and whether the early encounter with texts in school is a positive or negative experience is significant for the boys? later attitude to reading.

Internship is a new form of interaction between the academic world and the market and a phenomena increasingly popular among elite universities in Europe. The educational system has traditionally kept an academic approach where the institutions for higher education have acted isolated without extensive influence from the market. Today pressure from the market has led to intensified interaction between the universities and companies among many European elite universities. We have carried out a situational analysis concerning interaction between the academic institutions and companies in Europe. More specifically, we looked at the potential for Stockholm School of Economics (SSE) to strengthen its position on the educational market by adjusting its strategies and implement internships as a part of the education.
