Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

The chief aim of this study is to investigate the impact of context on written peer response. A second aim is to explore students? attitudes towards peer response. The investigation has taken place at an upper secondary school in the south-east of Sweden, involving 20 students in grade 2 and 3 in the course Swedish C. The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.

This paper deals with archaeological prospecting for the purpose of finding a prehistoric settlement in Alsike hage, Alsike parish, Uppland. The methods being used are soil phosphate analysis, electromagnetic survey and settlement analysis. Two 20x20 meters areas have been prospected. As Alsike hage contains several late Iron Age burial fields, large splendid zones for settlement location, closeness to water as well as farmland there was a hope of locating remains of prehistoric settlement in the area. None of the prospected areas showed any distinct evidence of settlement remains.

The purpose of this thesis is to investigate the degree of influence of holes in the web of steel beams with long spanson weakening of their bearing capacity. Making holes in the web of the beam generally reduces the bearing capacity of the beam. However, it might be necessary seen from both an architectural perspective as well as from a building services perspective by creating an opportunity for building installations.The objective of this thesis is to examine how much an I-beam can be weakened without sacrificing safety and functionality. The investigation has been done by using Finite Element Method through commercial software.The regulation for structural design of building structures in Sweden used to be specified in the document known as BKR. But this was replaced by the European norm Eurocode back in May 2011.

In this essay I have studied Aftonbladets portrayal of the Swedish businessman Jan Stenbeck and if the reporting changes before and after his death, and if so, in which ways. With help from a qualitative syntax analysis and a content analysis I studied my material about Stenbeck during the time period 2000-09-19 to 2004-09-19. In my quantitative analysis I studied 140 articles and in my syntax analysis I studied ten articles, five before and five after Stenbecks death. The theoretical perspectives that I applied in my study is Sigurd Allerns theory about tabloid papers novelty criteria and Adam Shehatas theory about Framing. Allerns theory describes what criteria the tabloid papers have on news and Shehatas theory about framing describes the political forces behind the news who wants to set their own agenda.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

This case-study examines the correlation between young men and democratic instability in group discussions with two analyzing methods in one. One part of the method used is deliberative democracy which aims to explain how democracy works within the frames of discussion in ordinary citizens groups. In this study the citizens is upper level secondary school students. The other part of the method used is the theory pulled by many scholars lately, the demographic impact on democracy. With these two combined in one this study compare the theory of young men as more active in political violence and as a destabilising factor of democracy on country-level with the results of the study in deliberative democracy in small group discussions.

The explosion of information technology has given users direct access to an ocean of information. Increased availability puts increasing demands on the ability of students and researchers to search for, filter, and structure information. In response, the role of the research library has shifted from being primarily an information resource to being an educational resource with a focus on teaching users what is known as information literacy. This thesis is a study of user-education at the Karolinska Institute Library KIB, the largest medical library in the Nordic countries. KIB has invested significant resources in developing user-education, and has a full-time user-education developer and a formal pedagogical platform for user-education.

Bakgrund: Prostatacancer är den vanligaste formen av cancer bland män i Sverige. Att få en cancerdiagnos innebär stress för både patienten och dess partner.Syfte: Syftet med denna studie var att undersöka grad av stressreaktioner i form av undvikande beteende och pa?trängande tankar hos patienter med prostatacancer och deras partner. Ytterligare ett syfte var att kvalitetssäkra mätinstrumentets formulering och svarsalternativ.Metod: Arbetet var en kvantitativ tvärsnittsstudie. Datainsamlingen gjordes med hjälp av enkät ?Impact of Event Scale? (IES) samt en enkät utformad enligt ?The Question and Answer Model? (QAM) för att kvalitetssäkra IES.

The study examines the price elasticity of demand for cigarettes in the short- and long run in Sweden. The time period for the study is 17 years and covers the years 1996-2012. The results of the study shows that the price elasticity of demand for cigarettes in the long run is higher than in the short run for the Swedish consumers, which is in line with previous studies in the area. The fact that the price elasticity of demand for cigarettes is higher in the long run, indicates that the substitution effect has a significant impact on the price elasticity of demand for cigarettes in the long run. The study was conducted in two parts where the authors investigated the effect of cigarette tax on cigarette prices and in addition the cigarette prices impact on the demand for cigarettes in Sweden.

For the last decades, Sweden has transformed from a state with strong elements of corporatism, to a governance of pluralistic character. This development has opened up to a new form of participation ? lobbyism ? which since has spread and commercialized. Because of this, a report on the state of Swedish democracy ? Demokratiutredningen ? was issued to examine the phenomenon of lobbyism as it was feared to challenge the functioning of a representative democracy.

This thesis will discuss teachers handling of the background, experience and earlier acquired knowledge of students. Our aim is to study the teachers? use of the cultural knowledge that of which the students already possess and the consideration the teachers have for the students own parental tongue. From this we want to see if there are any obstacles or pits with the work of gathering up experiences. The study is based on interviews with seven different teachers at a multi cultural elementary school in one the suburbs of Stockholm.

New innovation and technology have influenced the development of product development processes and the four largest banks in Sweden have more or less been forced to adapt their products and services along new customer requirements. It may therefore be considered appropriate to involve customers in this process. This by collecting customer information and allow customers to influence the process to a greater extent. The payment solutions of Sweden?s largest banks' continue to evolve and to pay with electronic money has come to change banks' product development processes of payment solutions.

The aim of this study was through applying a new perspective reach the people who during medieval time lived and worked on the farm. On the basis of my previously study and a gender perspective this study have compared general literature with local and then interpreted the farm from a local context. The questions raised here concerns division of work and spatial distribution on the farm as well as local impact on gender constructions.This study resulted in interesting problems within the archaeology itself but also in significant details about the farm. No gender restrictions could be seen in the houses except in Hus 1 were a smaller space, which probably used as storage or a workshop had been restricted tomales. Instead the buildings social space mainly consisted of a mixed gender environment.

To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.
