In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

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.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Kursutvärderingar kan ge svar på många frågor, och leda till ett väl motiverat förbättrings- och utvecklingsarbete. De kan även vara mycket svåra att genomföra. Forskning visar att utvärderingar ofta saknar tydliga mål, vilket leder till att resultaten blir svåra att använda. I detta examensarbete diskuteras kursutvärderingarna på företaget Kärnkraftsäkerhet och Utbildning. Målet är att arbetet ska leda till elevenkäter och undersökningsresultat som kan bidra till utvecklingen av kurserna vid Kärnkraftsäkerhet och Utbildning i Barsebäck.

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..

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.

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.

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).

Mastitis in dairy cows is an emerging and challenging disease in the tropics, including India. Nation-wide reports suggest that the incidence of clinical mastitis varies from 3.94% to 23.25%, and for subclinical mastitis from 15.78% to 81.60%. In Assam, a northeastern province of India, dairy is an essential part of the mixed farming system that exists in the state, but the milk yield is far below domestic standards. In 2009-2010, International Livestock Research Institute (ILRI) and local associates started to develop a training program for local farmers in Assam, in order to enhance the informal bovine dairy sector in and around Guwahati, India. The project continued until mid-2013.
