Jämförelse av resultat mellan manuell gelkortsanalys och automatisk immunohematologisk gelkortsanalys vid utförande av blodgruppskontroll och antikroppsscreening (BAS-test)
Incompatibility between donors and recipients can cause fatal hemolytic transfusion reactions (HTR), kidney damage and death and immunization of the recipient. Antigens on the surface of erythrocytes in the ABO blood group system and regular natural antibodies against these in the patient?s plasma must be considered. An individual always has a corresponding antibody of IgM in their plasma. Irregular antibodies acquired by transfusion or pregnancy and active in body temperature also cause the HTR incompatibility.
Kontextmedvetenhet som ett sätt att reducera Information Overload : Designriktlinjer för kontextmedvetna smartphone-applikationer
The main topic of this thesis is to evaluate the impact on the usability of web pages when using responsive web design, a concept for developing web pages whose design adapts to the screen size being used. This is done by creating a responsive prototype based on an existing web site. A number of usability tests are conducted on the two versions of the site in order to compare the time to complete the tests and to observe the behaviour of the test participants. The tests are conducted on desktop as well as on mobile devices with varying screen size.The number of test participants was relatively low, and so the quantitative result is not statistically valid. However, the conclusion is that the most effective combination is to use either of the sites on desktop format.
Begreppet hållbar utveckling : Dess historia samt internationella och lokala användning
This thesis is a case study of the search function on the University of Uppsala?s web site. The search function in this study was chosen since it exists on a large and complex web site and there were apparent lacks in the old version of the search function. The thesis highlights some of the problems that can appear in the development of a search function on a local site. One interesting find is that one of the most difficult issues is organizational and not technical.
Globalt mode på en lokal marknad : - En case study av H&M och hur de väljer att profilera sig i deras globala kampanj, Conscious Collection
The aim of this research is to develop a better understanding of how preschool-teachers respond to children in preschool, when they show that they want to have some influence. I have concentrated this study on how the preschool-teachers respond to the children in the gatherings and when the children are playing freely indoors, where the questions at issue are:How do the preschool-teachers respond to the children?s initiative for participation in the gathering and while playing freely?There have been four preschool-teachers and 14 children who have taken part in this study. The children who took part are in the ages of three to five. The study was done at a section in a preschool in middle Sweden.The method used in this study is unstructured observations.
Ska vi träffas på biblioteket? En undersökning om folkbibliotekets funktion som mötesplats
The aim of this Master thesis is to study the public libraries' function as a place for people to meet. Four major questions are taken up: + Do the public libraries have the function of a meeting place? + How important do the librarians and the visitors find the libraries possible function as a meeting place? Do they think that this function is important? + What differs the public libraries from other places in society when it comes to the function of a meeting place? + What differences are there between a larger and a smaller library when it comes to the function of a meeting place ? The basis of this study are interviews with employees at a province library in Jönköping and at a smaller library in Sjöbo in Borås municipality. Our study deals with the history of public libraries, its functions as a meeting place, its architecture, culture, and statistics concerning numbers of visitors and loans of books. The conclusions that are drawn are that the public libraries have qualifications to function as a meeting place even if that isn't always the case.
Kan grad av degenerativ hjärnsjukdom prediceras med hjälp av mått på kognitiv försämring?
Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.
En beskrivning av manuellt test : Svagheter och styrkor med och utan stöd avett testverktyg
Test is an area in system development. Test can be performed manually or automated. Test activities can be supported by Word documents and Excel sheets for documenting and executing test cases and as well for follow up, but there are also new test tools designed to support and facilitate the testing process and the activities of the test. This study has described manual test and identified strengths and weaknesses of manual testing with a testing tool called Microsoft Test Manager (MTM) and of manual testing using test cases and test log templates developed by the testers at Sogeti. The result that emerged from the problem and strength analysis and the analysis of literature studies and firsthand experiences (in terms of creating, documenting and executing test cases) addresses the issue of the following weaknesses and strengths.

Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.
Användbarheten hos WNV: granskning av ett nytt icke-verbalt intelligenstest för barn
This paper investigates the usability of the intelligence test Wechsler Nonverbal Scale of Ability (WNV). Twenty four children in two different age-groups were tested with WNV, 10 children between ages 5 - 6, and 14 children between ages 9 - 10. The WNV turned out to be a useful test when some verbal communication was used in the test situation. This was especially apparent among the younger children, who needed extra verbal instructions and verbal support through the different subtests. The test also contained standardized verbal instructions for all ages.

USA:s m?ngfacetterade strategi i Myanmar En komparativ analys av liberalism och realism i amerikansk utrikespolitik
This thesis examines the USA?s response to the military coup in Myanmar 2021 through a
comparative analysis of the two dominant international relations theories: realism and
liberalism. The study uses a qualitative text analysis of the US Burma act of 2021 to test the
explanatory power of the theories in the formulation of US policy. The results shows that
liberal theory has the greater explanatory power, as the US response was systematically
motivated by a normative desire to restore democracy in Myanmar. However, some realist
tendencies could be observed, especially through exception clauses preserving US national
security interest and the mention of China?s support for the military junta in Myanmar.
Värdet av demand response på den svenska elmarknaden
Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.
Insatsens akustik och dess påverkan på hörapparatens förstärkning
The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.
Att genom design effektivisera räddningsinsatsen för motorcyklister i trafikolycka
What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..
Svarar människor mer eller mindre socialt önskvärt beroende på hur de genomför ett personlighetstest?
A personality test is a useful tool in recruitment contexts. Studies have shown that participants distort their answers in a socially desirable manner. The purpose of this study was to investigate if people respond more or less socially desirable depending on how they rate themselves in a personality test, based on the "big five" personality dimensions.Eighty people, (40 women and 40 men), 19-42 years, (M= 24,1 SD= 3,76) rated themselves on a personality test. Group one, (20 women and 20 men) completed the test on paper. Group two, (20 women and 20 men) completed the test verbally.
