Konstruktion av kostnadseffektiv fläkt till härdningsugnar

Scana-Booforge is a Swedish company which specialize in heat treatment of various metal. The treatments take place in quenching ovens, where fans are used to circulate the hot air. The fans used today do not have a satisfactory lifespan. This thesis aims to develop a new design of the fans for the quenching ovens, and the goal is that the new fans will bring cost savings for Scana-Booforge.The design development process started with mapping out the environment in which the fans operate, and with analysis of the existing fan structure and damages, in order to establish the cause of failure and of short durability. The performance of the fan were also established at this stage.

Translationsnoggrannhet i läsningen mellan tRNA och mRNA : En analys av variationen i den maximala diskrimineringen d i initialselektion

The purpose of this thesis is to analyze the variation in the maximal discrimination of the interaction between cognate and a non-cognate codon and anti-codon (also called the d-value). The variation was analyzed with a multiple regression model with the d-value as the dependent variable and with the codon position and the different mRNA and tRNA bases as independent variables. The result of the analysis not only confirmed earlier studies that the maximal accuracy was highest in the second codon position and lowest in the third codon position but we also found significant relationships and interaction effects..

Rättvis värdering av hälsa : En kvantitativ jämförelse mellan Person Trade Off- och Time Trade Off- metoden

One must consider cost effectiveness when deciding how resources within the health sector should be distributed. Quality adjusted life years (QALYs) are used to measure the value of different medical treatments. QALY is based on utility maximization theory, which suggests that a QALY is always a QALY regardless of who receives it. Therefore, a produced QALY is worth the same regardless of the age or the initial health of the patient. Previous research has shown that these assumptions do not seem to fit the real preferences of individuals.

Tala är silver : ?- En kvalitativ studie om synen på dialekter

SAMMANFATTNING Syftet med denna studie var att undersöka om det finns något samband mellan dialekter och åhörarnas förväntningar på identitet hos den dialekttalande. Är våra förväntningar så hårt inpräntade av tidigare erfarenheter att vi analyserar en person, och dömer den enbart med hjälp av personens dialekt? Frågeställningarna blev följande: hur ser intervjupersonerna på sin egen dialekt? På vilket sätt påverkas intervjupersonen av de olika dialekterna samt vilka förutfattade meningar, sedan tidigare erfarenheter, om dialektbrukarens identitet går att finna hos dessa intervjupersoner? Metodologiskt användes en semistrukturerad intervjuform som åtföljdes av en ram som fångade in olika huvudteman. Urvalet bestod av tolv intervjupersoner i åldrarna 20-30 år. Intervjuerna varade mellan 30-40 minuter.

Från John Silver till Kapten Nemo : En studie i arbetet med klassikerläsning i en årskurs åtta

Syftet med den här studien är att undersöka hur ett projekt med klassikerläsning i en årskurs åtta går till. Frågeställningarna är hur och varför läraren väljer att lägga upp undervisningen på ett visst sätt, hur eleverna upplever läsningen och lärarens undervisning, samt om det finns några skillnader mellan killar och tjejers läsning. Undersökningen är kvalitativ och har ett didaktiskt och ett receptionsteoretiskt perspektiv. Resultatet visar att läraren konstruerar svenskämnet utifrån ett erfarenhetspedagogiskt perspektiv med skönlitteraturen i centrum och att hon använder sig av litteräranalytiska redskap som beskrivning av tid, huvudperson och handling. Tjejerna är generellt mer positiva till läsning än killarna.

EU - ett medel i kampen mot organiserad brottslighet : En fallstudie av hur EU bekämpar organiserad brottslighet i Italien

?During the past few years cooperation between the EU member states has expanded considerably in areas such as justice and homeland affairs. International cooperation in criminal justice has become more important as borders between EU countries has been lifted and because of this, various criminal groups have also had more opportunities to commit crimes cross borders. The Italian mafia groups in particularly have been operating in almost every country in Europe and have exploited the possibilities offered by the EU. The increase of organized crime in Europe has created a demand for EU to step up their actions against the organized crime.The purpose of this essay is to investigate exactly how the significant EU is has been in battling organized crime in Italy.

Datorbaserad examination: En studie om användarhinder och systemacceptans bland lärare

The aim of this thesis is to examine how teachers use computer based assessment in their work and what user barriers they experience while working with computer based assessments. The result of the thesis is meant to provide an understanding of which factors affect the use of computer based assessments and how a company who provide computer based assessments applications can increase the rate of use amongst teachers.To investigate this, the author examined a company in Sweden who provide a computer based assessment application for both universities and high schools. The study was carried out at two different schools, a university and a high school, both located in Stockholm. In total nine teachers were interviewed. The author also conducted observations at the company whose computer based assessment application was examined.The author?s findings suggest that a lack of functions within the application and lack of costumer support from the company all negatively impacted the teacher?s use of the application.

När tiga är silver och tala är guld - hur organisationer behandlar negativ publicitet internt

Syftet med uppsatsen är att öka förståelsen för hur organisationer som utsätts för negativ publicitet bör kommunicera med medarbetarna, för att bibehålla deras förtroende för organisationen. Vi har genomfört en kvalitativ fallstudie där vi samlat in vår empiri genom semistrukturerade intervjuer. Upprättandet av en dialog är det effektivaste kommunikationsmedlet för att kommunicera med medarbetare. För stora organisationer är det svårt att upprätta en genomgående dialog på alla nivåer, och även om den i viss mån förekommer i den dagliga kommunikationen, så uppstår svårigheter när negativ publicitet ska kommuniceras på ett internt plan. Trots att begränsade resurser kan hindra optimal kommunikation vid negativ publicitet, är det viktigt att ledningen inte tiger, utan kommenterar det inträffade.

Honung och biodling : honungens ursprung, egenskaper och effekter på människans hälsa

This report describes honey, its origin, properties and effects on human health. Honey has been used for a long time in most civilizations and apiculture is an important activity sector in many parts of the world. The trend is an increase in honey production but a decrease in the number of beekeepers in Sweden. Honeybees live in a highly developed society with a strong hierarchy and a well organized distribution of the tasks. They visit a broad spectrum of plants and collect nectar to store it as honey.

?Jag tycker bara att jag gör vad jag vet att jag kan göra? : en undersökning av en webbaserad bibliotekskatalogs användarvänlighet utifrån användarnas perspektiv

The purpose of this Master's thesis is to examine whether a web-based library catalogue is to be considered user-friendly. We have examined this from a user-perspective by interviewing users of a web-based catalogue at a public library. In order to get a picture of the user-friendliness of a catalogue, the thesis is centred upon the following questions: How is a web-based catalogue used? What problems do the users experience? How is the catalogue perceived by its users? Since the producers of these catalogues now are taking into account the research upon human-computer interaction, we are also interested in finding out whether a web-based catalogue is more user-friendly than a more traditional OPAC. We do this by comparing the results of our examination with earlier studies of OPAC use.

Diabetes hos hund : en uppföljning av behandlade hundar ur ett djurägarperspektiv

Diabetes Mellitus is one of the most common endocrinologic disorders among dogs. The disorder has a complex background, and successful treatment requires a well-functioning co-operation between pet owners and the veterinarian. The purpose of this study is to investigate the owners? perspective of diabetic treatments offered, and to estimate expected length of survival post-insulin therapy. The research findings are based on a survey mailed to 77 pet owners, whose dogs were diagnosed with diabetes between 1999 and 2003 at the small animal clinic of the Swedish University of Agricultural Sciences. The median survival for the dogs that underwent insulin treatment was 31 months, i.e.

In this degree project I have studied how an anti-discrimination bureau can adapttheir online information to the target group ? immigrants who only have modestunderstanding of the Swedish language. This group is often subject of discriminationmatters, and therefore it?s important that they can take part of the information.To find answers to my questions I have studied different relevant theories, performeda readability analysis on the online information and have had qualitativeinterviews with representatives from the target group. I have also tested my rewrittentexts on both representatives and other readers.The result from my studies has shown that it is words that are the most difficult inthe current online information, while length and structure of the sentences are alsoof importance when it comes to the readability.

Äldre mäns erfarenheter när sexualiteten påverkas vid prostatacancer : En litteraturbaserad studie

Background: Prostate cancer is the fourth most common cancer disease in the world and affects mainly older men. While having prostate cancer the treatment can be both medical and surgical and both these treatments can give side effects like erectile dysfunction, lost libido and hot flushes. Sexuality among elderly is often associated with taboo, but sexuality exists among elderly and is important for their wellbeing and quality of life. It is common that nurses don?t address and discuss questions concerning sexuality with patients, even though they know that sexuality often is affected while having a disease or experiencing illness.

LIKHET ELLER SKILLNAD? : Om hur ambassadörer för UNICEF i Sverige representeras i relation till barn/?de Andra? utifrån könade och rasifierade diskurser om bistånd

This essay aims to examine what subject positions are possible within the discourse of relationship anarchy. Through semi-structured interviews with four people who define themselves as relationship anarchists I've made a discourse analysis to determine how these relationship anarchists explain what, in the discourse they?re in, is described as an relationship anarchistic way of being, what isn?t and how they relate to this. Relationship anarchy is described as an ideology based on freedom. It is about the right to define their relationships as they like, as something constantly changing and that does not hold a specific value based on its label.
