When exposed to them, isocyanates can induce serious injuries in the respiratory tract and irritation on the skin and in the eyes. They are therefore interesting from the point of view of occupational health. The purpose of this thesis was to collect isocyanates in air with impinger-filter samplers and solvent free samplers. Furthermore the isocyanates were to be analyzed with liquid chromatography-mass spectrometry. The solvent free sampler consists of a polypropylene tube and filter holder fitted with glass fiber filters impregnated with derivatization reagent, coupled with a pump.

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.

The essay concerns the role of fiction in school. The research questions is; what is ?readable?, what does the authors think of teacher's task to develop students' literacy skills through fiction and how do the authors think of the teachers' task of using fiction in school. The questions give a basis that describes the role of fiction in school today based on the authors' perspective. We have chosen to use the open surveys as a method.

The aim of the study was to investigate the students´ attitudes towards mathematics, their knowledge in the subject area they find the least interesting and whether laborative/practical working methods could awaken their interest and curiosity. During our work, we have looked into previous studies regarding girls´ and boys´ attitude and performance in mathematics. We handed out surveys to students in grade 9 at a School with many people from other cultures and nationalities in Malmö in order to find the answers to our questions. The result showed that most of the students thought that the subject area "scaling" was the least interesting. The implemented action program was a laborative/practical task within the "scaling" area.

This assignment has been performed at location and commissioned by AttenditAB in Jönköping. The task has been to develop a client/server system to accessdata stored in SQL databases where the client application is developed to run onregular cellular telephones. The importance has been to develop as reliable mobilecommunication as possible. The functionality that is demanded upon the mobilecommunication is:? Secured for future versions? Interoperability? Data should not be bugged, modified or disappearunnoticed? Resource efficientWe have achieved these demands by developing our own protocol that is on top ofthe TCP protocol.

Det här examensarbetet är baserat på idéer ur ett uppdrag från företaget Saab Aerotech men är ett eget arbete.Målet var att undersöka om det finns behov av ett verktyg som statiskt kan detektera dynamiska minneshanteringsproblem, som till exempel minnesläckage, i applikationer skrivna i C/C++. På grund av att minneshanteringsfel i C/C++ länge har varit ett känt problem undersökte vi detta och de befintliga lösningarna till det.Vi fann två metoder till lösningar som de flesta verktyg använde sig av; statisk och dynamisk detektering. De flesta verktyg löste problemet genom att dynamiskt detektera minnesläckor och andra brister som till exempel buffer overflows. Ett verktyg löste dock problemet genom att statisk detektera minneshanteringsfel i källkoden för applikationerna. Eftersom alla befintliga lösningar har någon form av ineffektivitet så har vi undersökt möjligheten att utveckla ett mer effektivt verktyg.

Literature describes what it is like to be a leader in the healthcare and what is looked upon as the most characteristic quality for female leadership. Women often use a leadership technique that motivates the employee and they allow themselves to develop a humanitarian leadership. The aim of this study was to describe female head nurses? experience of their leadership in healthcare. The collection of data has been carried out from interviews.

The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.

It is statutory that teachers shall document their student's development of knowledge in different subjects. The teachers employed by Sundbybergs municipality have been commissioned to do the documentation in the web-based electronic system Projekt- och Omdömesdatabasen, P.O.D.B. The purpose of this study was to investigate witch effect the IT-solution P.O.D.B has brought for the teachers in their task of student documentation. By conducting interviews and questionnaire studies I have been looking for answers to if the target achievements have increased by using the IT-solution, and if the teachers are aware of what they may or may not write about their students in the system. The conclusions I have been able to draw through my studies are that the teachers have accepted the commission to use P.O.D.B.

The purpose of this study is to investigate and describe what factors are most important to students when choosing training center, and how these factors affect the choice of each training center. We investigated this by performing a qualitative research and a quantitative survey of students at Karlstad University that trains at Friskis & Svettis and Sats in Karlstad. The results show that there are a number of important factors in the total customer experience that affects a student's choice of training center and that they also differ between a premium center and basic center. Our conclusion is that when a total customer experience concept consists of a core, core experience and peripheral experiences well linked into each other competitive advantages is created, resulting in more satisfied and loyal customers. .

Today many people immigrate to Sweden, many of them with another religious belonging than the Christian. According to Lpfö98 and Lpo94, the Kindergarten and the school have the task to help alla the pupils to develop an understanding for their own cultural inheritance and the the swedish culture. The task is also to make the pupils feel as a part of the common culture.The aim with this essay is to investigate if - and how - the teachers in two different schools are u sing the immigrant pupils experiences and knowledge about other cultures and religions than the Christian. Does the teachers use the parents of the immigrant pupils or other relatives as a resource in their teaching?We also wanted to investigate what the teachers are doing with the pupils of another religious belonging than the Christian, who is not allowed to join the celebration of Christian festivals in school, such as Easter, Christmas and breaking-up ceremonies in the church.In this essay we have used a form.

The purpose of this thesis is to present a review of research themes and practice in the field of art image registration. The objectives of the review are twofold. The primary task is to distinguish which problems, in regard to theory and practice, that have been dealt with in the field of art image registration and the secondary task is to investigate which discursive, institutional and tool-related factors have had an impact on theoretical discussions and practice in the art image domain. The empirical content in the review is structured according to four epistemological viewpoints and is analyzed with a domain analytical approach. The result of the study is that two major problems are frequently discussed in the art image domain, namely lack of standardization and which discourse is the best suited for registration of art images.
