Utredning av laserskärningens materialpåverkan inför drag- och slagprovning : Teknisk Fysik med Materialvetenskap

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

Träden : en naturlig inspiration kring lärande i naturen

The aim of our study was to examine Swedish crime reporters? approach to the social medium Flashback. Our main focus was the crime reporters? use of the medium Flashback, and attitude towards their own use of media ethics in relation to the medium Flashback.Flashback as a medium is not obliged to any media ethics and lacks a legally accountable publisher. In the search for information about committed crimes people tends to visit Flashback for the information that the traditional media cannot offer.

Eskortverksamhet med fokus på försäljning av BDSM-tjänster

The purpose of this study is to examine escort-business with a focus on sales of BDSM-services (Bondage and Discipline, Dominance and Submission, Sadism and Masochism). The study is based on qualitative interviews with three informants providing BDSM-services, as well as a survey with 96 men who requested domination of escorts (the survey was carried out by an escort in the 1980s). The analysis of this material resulted in the identification of three themes on which the study centers: The personal experiences of the three escorts, the interaction between the escorts and the clients, and the changes over time when it comes to the performance of BDSM-services. The study has a gender perspective with a focus on feminism and queer-theory. The important conclusions are that there are several differences between prostitution having a focus on BDSM-services and other prostitution.

Mjölkkors välbefinnande i AMS och konventionell lösdrift : skillnader i beteende och hormonstatus för oxytosin och kortisol mellan kor av hög och låg social rang

The purpose with this study was to investigate how the behaviour and physiological parameters differ between high ranked and low ranked cows, and between cows in an automatic milking system verses conventional milking parlour. The study was carried out at the Kungsängen research Centre, Department of animal nutrition an management, Swedish University of Agriculture Sciences, Uppsala. Twelve cows, the six highest and the six lowest in social rank were selected from the automatic milking system for the experiment. Ten cows, the five highest and five lowest in social rank were selected from the conventional system. Blood samples were taken during milking and resting.

Energikartläggning av ett 1970-tals lägenhetshus på Skarpövägen i Nacka kommun : Simulering av energibesparande åtgärder i ?IDA Indoor Climate and Energy?

This study has been carried out in the spring of 2014 on behalf of PQR Consult AB in Stockholm. The aim of the study has been to analyse the energy usage of the building Skarpövägen 1 in order to explore the possibilites of saving energy by using appropriate equipment. These possible solutions have been simulated by using the programe IDA Indoor Climate and Energy, combined with a life cycle cost analysis. The laundry building, Skarövägen 23, has also been analysed due to its high amount of energy usage. The result of the energy analysis showed that the energy usage was much higher than the energy declaration.

Resurser för närstående på Sveriges intensivvårdsavdelningar - En kartläggning

In the care for the critically ill patient the next of kin is of great importance. Their support, love and care for the patient, increases the wellbeing and makes a connection to the patient?s normal lifeworld. For the next of kin to be able to be that support the next of kin needs to be helped to maintain the basic need of for example their sleep, food, hygiene and psychosocial support. The critical care nurse must see to the patient?s whole lifeworld which includes their next of kin.The aim of the study was to identify the resources available for the next of kin in intensive care units in Sweden.

"Det är inget fel på dig!" - en kvalitativ studie om upplevelser av stöd hos kvinnor med diagnosen vestibulit

Background: Documents and legislation inform us that parts of the public health service of Sweden, at a political level, aim to support people?s sexual health. Statistics show there has been an increase among young woman, seeking help for sexual pain during intercourse. The diagnosis that the media has come to observe lately is vulvar vestibulitis. In general there is a lack of knowledge about the existence of this state of pain and its causes, which impacts woman to get appropriate help and support in time.

Optimization and validation of a triplex real-time PCR assay for thermotolerant Campylobacter species associated with foodborne disease

The genus Campylobacter is globally recognised as the leading bacterial cause of human foodborne gastroenteritis. Every year around 8000 Swedes are infected by Campylobacter. Most people are infected by thermotolerant Campylobacter species, commonly C. jejuni and C. coli.

Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden

Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.

Analys av åldersstrukturen hos sik (Coregonus lavaretus) i sjöar utan gädda (Esox lucius)

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

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.

Pseudoslumptalsgenerering : En studie av pseudoslumpsalgoritmer i allmänhet med fokus på C++11-biblioteketRandom samt implementation av en modifierad XORShift

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..
