Mjölkureahalten som mått på vommikrobernas kväveförsörjning och kons miljöbelastning
The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.

Effect of insulin during oocyte maturation in vitro on bovine early embryo development : partially evaluated by novel fluorescent staining
Fertility is of central interest in the dairy production but has during the last decades declined. Increased milk yield has resulted in high pressure on the metabolism of the dairy cows that are supposed to manage the transition from dry cows to lactating cows within a few weeks around the parturition. Much indicate that metabolism and fertility are closely linked, with insulin playing a substantial part. There are many studies suggesting that the main part of gestation loss can be found during the early embryo development, a period which can be studied in vitro. The aim of this study was to test the effect of insulin during maturation in vitro and to evaluate two different fluorescent stainings on oocytes and embryos; a nuclear stain and a staining of apoptotic cells through the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)-method.

Inredningsförslag till Bolandgymnasiets matsal
My bachelor?s dissertation concerns the creation of a proposal for interior decoration of the Boland High School?s canteen. I have been in contact with personnel, students and the school principal through the duration of the project. In the end, substantive changes of lighting, interior decoration and movement were proposed for the canteen. In the proposal I have focused on accentuating the school?s profile, on creating smaller spatial configurations within the larger configuration of the room, lowering the noise level, creating a good movement flow, increase the number of seats and creating a pleasant environment in which to eat..
Commercialisation of inventions from a legal and business perspective
This thesis is about university spin-offs and the competition in high technology industries. In the light of efforts to increase the competitiveness of the European Union, an effective transfer of cutting edge technology from universities to the industry plays an important role. University spin-offs, start-ups founded to exploit academic inventions, are likely to face considerable market entry barriers. This is among other reasons due to high capital requirements for further technology development and lack of complementary resources. With a combination of relevant literature and empirical investigation, commercialisation of technologies within spin-offs is investigated and analysed.
Att vara eller inte vara motiverad och kreativ i teaterprojektmiljö : En undersökning av motivationsfaktorer och kreativitet i en teaterorganisation.
Abstract Project as a method was defined in the American defense industry in the 1950´s and has since then developed to encompass many different areas such as industrial management, administration, research and development and IT etc. In the cultural sector project is a common way of organizing work and within theatre, which is the focus of this study, one can claim that project as a form of work has been used for hundreds of years, if not by definition.Theatre is generally assumed to be an form of art representing creativity and innovation, highly demanding from an individual perspective relative to the project result, i.e. the final performance. Time pressure, fierce competition, limited resources and responsibility to deliver on time with high quality are natural conditions given.The aim of the study is to find out what circumstances and conditions affect and have a clear impact on motivation and creativity in those working professionally within theatre.This study is based upon qualitative interviews with a limited number of employees with different occupations, within a major publicly-funded Swedish theatre institution.Contemporary research indicates both intrinsic and extrinsic motivation as essential for how we experience and commit ourselves to our work, either as two separate forces but also as they interact.Extensive studies further state our individual experience from work, the conditions provided by the organization and social environment as crucial to our work performance. A positive experience from these factors enhance our motivation and creativity.The results of this study show theatre to be an activity supported by strong visions and clear goals where challenge and creativity are essential and where it´s members show strong commitment to the task whether they are beside or on the stage..
"GODNATTSAGAN - Vart tog den vägen?" : En undersökning av småbarnsföräldrars aktiviteter tillsammans med sina barn.
The overall purpose of this essay is to come to a deeper understanding about videos in the Youtube beauty community by using a mixture of qualitative and quantitative methods. By answering the main questions of the essay which are; What quantitatively measurable components are there in the videos that can be seen as contributing factors leading to the fact that some generate more views that others?; Is there a set mold for success containing certain aspects that a video must have to stand out?; What correlations can be found between the two categories of analysis and how do these potential correlations affect the popularity of the video? and What effects do specific components on the level of popularity of the video?, we?ve been able to distinguish differences as well as similarities on both qualitative and quantitative levels. We have also seen that using the two methods together have enabled us to reach more profound results. The main result that we have found on a quantitative level is that there are obvious correlations between a high level of popularity and a good visual quality.
Humant papillomvirus : Gymnasieelevers kunskaper om och attityder till HPV, HPV-vaccin, kondomanvändning och cellprovtagning
Purpose: To assess awareness and attitudes regarding HPV, HPV-vaccines, use of condom and participation in pap-smear screening among high-school students in Uppsala County. The intention was also to investigate if there were any differences between students at theoretical programmes and vocational programmes.Methods: 608 students from seven high-schools in Uppsala County answered a questionnaire covering demographics, awareness and attitudes regarding HPV, HPV-vaccine, use of condoms and pap-smear tests.Results: A majority of the students had never heard of HPV (86 %, n=521), HPV-vaccine (94 %, n=537) or the link between HPV and cervical cancer (88 %, n=563). Most respondents had a positive attitude towards HPV-vaccine (84 %, n=508), but the biggest obstacle was the high cost (37 %, n=227). The students believed that it was less likely that they would use a condom with a new partner if vaccinated (mean=78, SD=26, p<0.001), or if they or their partner used contraceptive pills (mean=62, SD=32, p<0.001) compared to how likely it was that they would use a condom in general with a new partner. The girls rated the probability that they would participate in a pap-smear screening as relatively low if vaccinated (mean=59 SD=27).
