Investigation of tissue factor mRNA levels in human platelets using real-time PCR
Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.
Referensarbete i Sverige och Tyskland ? en jämförelse
The purpose of this Master thesis is to compare the perception and significance of reference work in two countries, Sweden and Germany. This will be achieved by means of a literature review of previous research literature and public documents and a content analysis of articles from two library journals.A first step was to examine the historical development of reference work in the selected countries. In connection with this there proved to be distinct phases in the discussion regarding reference work. These phases with their specific discourses, themes and emphases reflected and thus later were confirmed in the second part of the study.The results show that despite some similarities there are also quite a few differences in how reference work is perceived in both countries. For Sweden, the idea of reference work was introduced relatively early.

acts.
Flickor och pojkar går i samma klass i Sverige : En undersökning om nyanlända elevers syn och uppfattning om den svenska skolan
The purpose of my study was to find out about the newly arrived students? views and perceptions of the Swedish high school, how this vision and perception looked like before they moved here, and if it has changed. I also wanted to find out how they perceived the meeting with the Swedish school, and if they believed that this meeting should or could be improved. In this study, I used a qualitative research method, the phenomenological method, in which I have used qualitative research interviews to collect the empirical data and detect patterns in my research. The theory I used is cultural encounters, and with it, I try to understand how people with different cultural backgrounds create interactions to work together in communities.
Accountability: En studie av hur omfattande omgivningens krav är på ett företags ansvar i tid och rum vid en etisk skandal
Internet and media have led to companies' operations becoming more visible and transparent to the public during the 21st century. Several notable corporate scandals have led to society placing greater demands on businesses to assume more accountability for their actions. This study aims to examine and develop existing research regarding accountability, by adding dimensions of time and space. More specifically, the study examines the extent to which stakeholders hold corporations accountable after the revelation of an ethical corporate scandal, through a qualitative case study on a pending lawsuit against the Swedish corporation Boliden. Our theory is based on John Roberts' (1991) research presented in the article "The Possibilities of Accountability" and Martin Messner's (2009) research presented in the article "The Limits of Accountability".
Effektivitetsundersokning av medeltida kastmaskiner

This study will highlight the refugee children?s personal experiences and their point of view regarding the schools preparatory class, ordinary class, together with other pupils behaviour against them in the social interaction.
Psykologisk diagnosticering av tvåspråkiga barn Hur tar skolan emot elever med inlärningssvårigheter i förberedelseklass?
Abstract Abstract
The aim of this essay was to investigate the level of the organizational state of readiness for receiving students with learning disabilities in classes specialized in working with students recently arrived in Sweden, called förberedelseklasser, which could be translated as preparational classes. I tried to do so by answering two questions:
*What routines do principals believe that the particular School has for dealing with cases in which a student in a preparational class is suspected to have some form of learning disability?
*What perception do teachers have in regards to whether or not the system at their School is well prepared for discovering and aiding students in preparational classes suspected to have learning disabilities?
The first question was directed to principals currently working in schools where a large part of the students are bilingual, and many of those recently arrived in Sweden. The second question was aimed at teachers that work in preparational classes.
By interviewing two principals and three teachers I came to the conclusion that the teachers believe that their students are often misplaced in preparational classes when in deed they should be placed in a special educations group. My essay also shows that both principals and teachers are dissatisfied with the amount of time the process of discovering, investigating and diagnosing a student with learning disabilities takes.
Värmesystemsutveckling
In cooperate with Asko Cylinda we have developed a new heat system too short the process
time and reduce the energy consume in a dishwasher and still have it too be a class AAA.
The environment and quality is important for the company too still be the number one on
the market, If they want too keep that position the product developed of new innovations will
be very important. The systems we have developed are more effective and reduce energy up
too 25 %. The process time is reduced too less than two hours, from the today two and
half-hour. The solutions are too heat up the rinse water and the dishwater at the same time,
with a new heating system and it make are solutions unique and effective. Its good for the
dish and the environment.
Prövning av liggtidssensorer som indikator på förestående kalvning hos dikor
The aim of the study was to find repetitive behavioral patterns pre calving that could be used as indications of calving in beef cattle. In the study sixteen Standing- and lying down sensors were attached to the leg of sixteen beef cows. Ten of the sixteen beef cows gave birth to calves during the trial period. From these ten cows, data from six cows were used to assess the sensors fitness for use as calving indicators. The analytical part of the experiment was divided into two parts, calculation of divergence of mean lying time within different time intervals, and the number of lying bouts.The first part consisted of optimization of an equation used to highlight divergence in mean lying time within eight different time intervals (3, 6, 9, 12, 15, 18, 21 and 24 hours).
IFRIC 15 : och dess påverkan på byggföretagens intäktsredovisning
The number of studies on IFRIC 15 is very limited. The available studies have either been conducted before the introduction of IFRIC 15 or at an early stage of the implementation. This study examines IFRIC 15s practice from a longer perspective. The purpose of this study is to explain the effect that the interpretation IFRIC 15 has had on accounting objectives and qualitative characteristics of the revenue recognition of Swedish construction companies. The study will also analyze whether the construction companies has changed their perception of IFRIC 15 after applying it form a longer time perspective.
Samhällets syn på fattigdom : En jämförelse av begreppen "nödtorftig vård" och "skälig levnadsnivå"
The purpose of this bachelor's thesis in social work has been to examine whether society's perception of poverty and poor people has changed over the more than 160 years have passed since the first national Poor regulation was enacted in Sweden. With a social constructionist approach and inspired by the critical discourse analysis we have conducted two studies to find answers to what differences and similarities between the concepts of scanty care (1847) and standards of living (2002). A study based on previous research was conducted to examine how society's perception of poverty has changed and designed in a historical perspective. We also conducted a textual analysis of relevant legal texts and legislative history to show how these texts reflect the society's official view of poverty based interventions targeted to poor people.The two sub-studies show that the concepts at different times in history has been crucial for the community support poor people were entitled to. Our overall conclusion is that despite today's advanced social policy there are many obvious similarities between the concepts of scanty care and standards of living.
"De öppnade portarna för mig och sa `hej då`" : en kvalitativ studie om personers berättelser som frihetsberövande på grund av misstanke till ett brott och tiden efter frisläppningen.
Being detained means that a person loses their freedom and have limited contact with others. Police can on suspicion of a crime arrest a person, in order that the suspected person won´t be able to eliminate evidence. Being convicted of a crime and go to prison is terrible, but what about the experiences of being detained on suspicion of a crime you did not commit? Our purpose with the study is exploring stories of people who have been detained. It´s about their time as detainees to the time they got free from suspicions of the crime.
Optimering av prestanda och utnyttjande av flertrådsteknik
The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..
Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering
Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.
