Denna rapport kommer att redogöra för NK-cellers (Naturliga mördarceller) beteende vid odopat tillstånd. Det vi kallar dopning är när NK-celler aktiveras genom interleukin-2, detta är en signalerande molekyl i vårt immunsystem som reglerar aktiviteten hos vita blodkroppar vilka utgör en del av immunförsvaret.Med hjälp av ett par mikroskopfilmer har vi kunnat följa varje enskild NK-cells migration(rörelse) och interaktion med våra målceller i ett prov under en 8-timmars period. De målceller vi använder är en sorts tumörceller, HEK 293T(Human embryonic kidney 293T cells. Vi har valt att spåra cellerna manuellt med ett program kallat ImageJ och automatiskt med ett matlabprogram, Baxter algorithm. Anledningen till att vi dessutom valt att spåra automatiskt är för att kunna avgöra hur väl detta program kan spåra celler.

Methods used are GIS-analyses, interviews with staff of Huddinge Municipality, and field observations.

AbstractTitle: The picture of the Swedish church - Young peoples image of the organization in comparison with the organizations profile (Bilden av Svenska kyrkan ? Unga människors image av organisationen i jämförelse med organisationens profil)Number of pages: 55 (57 including enclosures)Author: Ebba GöranzonTutor: Göran SvenssonCourse: Media and Communication Studies CPeriod: Fall 2006University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The aim of this essay is to study the external communication of the Swedish Church, and how they want young people (16-18 years old) to perceive them. Further I would like to compare that information with how young people actually perceive the Swedish church. Do the both pictures agree?Method/Material: Together with literature studies, a qualitive method has been used and four focus group interviews with a total of 16 informants have been conducted.

This thesis deals with information provision to the knowledge intense biotechnology businesses of Ideon Science Park in Lund, Sweden. Previous research concerning the information needs of Science Park companies has been conducted from the information provider s perspective. Instead, we apply a user perspective to find out what information needs these companies have, and how they prefer to acquire information. Central terms are: information, -needs, -acquisition, -consciousness, -strategy, small and medium sized enterprises, scientists and engineers, information (resources) management, networks, tacit knowledge, knowledge transfer and innovative milieux. The companies need scientific and business information; the latter is easily obtained within Ideon.

I dagens samhälle blir det allt mer intressant att spara energi, dels med tanke på miljön och dels föratt minska på utgifterna. Denna energi ska sparas på ett sådant sätt att effekten för användarna blirså liten som möjligt.I denna rapport beskrivs hur ett reglersystem kan byggas för att minska energiförbrukningen hosväxthus genom att reglera belysningen på ett effektivt sätt. Systemet är helt automatiskt vilket göratt användarna inte behöver tänka på styrningen av lamporna alls när väl systemet är uppsatt ochkonfigurerat.För att styra lamporna på ett bra sätt mäts det inkommande ljuset med en PAR-sensor. Lampornatänds och släcks därefter beroende på ljusmängden och även på hur varmt, eller kallt, det är iväxthusen.Styrningen av belysningen sker med en mikrokontroller från Microchip, en PIC18F4620 som ärprogrammerad i C18. Kringkomponenter som portexpasioner, klocka och reläer användes också föratt bygga ett bra reglersystem.Resultatet är att det är möjligt att bygga ett reglersystem med begränsad budget som styr lampornapå ett effektivt sätt.

Bakgrund: Ventrikeldränage används inom neurokirurgisk vård för medicinsk behandling, dränering av likvor samt mätning av intrakraniellt tryck. En infektion relaterat till ett ventrikeldränage kan vara livshotande och ge permanenta skador hos patienten. Syfte: Att analysera dokumenterade skillnader i ventrikeldränagerelaterade infektioner, vårdtid och mortalitet, före och efter införande av nya hygienrutiner - ett åtgärdspaket. Metod: Ett åtgärdspaket med medicinska- och omvårdnadsåtgärder har med hjälp av genombrottsmetoden tagits fram för att minska de ventrikeldränagerelaterade infektionerna. Studien är kvantitativ med empirisk ansats.

Denna studie är inriktad mot ordavkodning vilket är en nödvändig faktor för god läsfärdighet. Redan från årskurs ett ger en snabb ordavkodningsförmåga en god prognos för elevers fortsatta läsutveckling. Studiens syfte är att undersöka om tre veckors intensiv upprepad läsning i helklass har positiva effekter på elevers ordavkodningsförmåga på vårterminen i årskurs ett. Upprepad läsning avses i denna studie när två elever läser högt för varandra i helklass. 28 elever i en undersökningsgrupp fick, varje morgon under tre veckor, läsa samma text fyra gånger vid det första lästillfället, och ytterligare en gång nästkommande dag.

And throughout the years many loanwords have been introduced to the Swedish vocabulary. And this phenomenon occurs in the texts written by Swedish sport journalists. But in what extent do loanwords from the English vocabulary occur in texts written by Swedish sportjournalists, in what types of texts they can be found. And also why the usage of loanwords occur.The purpose of our study is to find out how frequent English loanwords are in Swedish sports journalism.

The present study examines the demolition of a house on Hammarkulletorget in 1996 and the discourse of Hammarkullen, Gothenburg(Sweden), drawn from the perspective of historicization [?historisering?]. I have examined how the past played role inpresentations of Hammarkullen and how the past affected the decision to demolish a house. By examining which role the neighbourhood?spast time played in the perception of the neighbourhood, the thesis aims at providing a better understanding of howthe past can influence and legitimize major changes in the urban environment.In the early 1980s the image of Hammarkullen as a victim of negative publicity is established and this reputation lives beyond thesimplistic and negative descriptions themselfs.

The setting of pupils' final grades in the Swedish upper secondary school system is the responsibility of their teachers and once grades are set, they are not open to appeal. This can be compared with the British system where an external, central examination board sets the final grades based on the result of externally marked examinations (A-levels). These grades are then open to appeal if it is felt that an injustice has been made.This research paper has been an investigation into how pupils in one Swedish upper secondary school attempt to influence their teachers in the grade-setting process and how these teachers are affected by these different methods. Five teachers in total were interviewed in a qualitative case study. The study has also taken up the controversial issue of how grades, which are set individually by thousands of teachers across the country, can be deemed to be fair and equivalent.The study revealed that pupils employ many different methods when trying to influence their teachers in the grade-setting process e.g.

Background and problem: The background to this study is the organizations increased difficulty to retain employees in the organization when more and more employees today choose to do their career in several organizations. The problem to keep the employees in the organization leads to several problems where the loss of experience reduces efficiency and increased risks and cost associated with recruitment are some problems that arise. The problem therefore faced for this study is: How can opportunities for career development within an organization created to get employees to stay over time?Purpose and method: The purpose for this study is to describe how organizations can create opportunities for the development of career that gets employees to stay within the same organization and make their career in this organization. The method used for this study is a qualitative approach where data is collected through semi-structured interviews in a case study.Empiricism: The empirical result have shown there are four factors that an organization should overhaul to create an opportunity for the development of a career that gets employees to stay in an organization over time.

This study draws from Zygmunt Bauman´s theory that a governmental policy of values can reduce the personal responsibility and moral choices for employees, to focus only on maintaining the government?s internal rules and regulations. The apparent risk with this type of moral attenuation is that the employee is deprived of the possibility to react morally on conduct of the government?s external misuse of power. In this study, this theory is connected to the Swedish Armed Forces? policy of values, as these values do not include a critical standpoint for officers and soldiers.

The strive for control over employees has developed throughout the years. This paper has its focus on how normative control can work as a powerful method to create and uphold a sought for behavior. Many companies have found an interest in a higher moral stance to get competitive advantages, and offer their customers and partners a more ethical product. This phenomenon has in Sweden resulted in a sphere of companies who has earned the R-licens. The R-licens is earned by companies if they fulfill ethical and cultural criteria.
