Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

The virus-mediated disease Rift Valley fever (RVF) was discovered during an outbreak in Kenya in the 1930s. Since then it has spread to most parts of Sub-Saharan Africa, and in the last decades several outbreaks have caused economic and health issues in Africa, Yemen and Saudi-Arabia. The disease mainly affects domestic livestock, causing abortions, but is also a zoonosis. To be able to control the spread of the disease it is important with surveillance for better knowledge about the distribution and virus circulation even in inter-epidemic/epizootic periods. The human population is growing, and people and their livestock constantly move closer to areas with wild animals which act as reservoirs for different viruses. Also, humans and their animals often get within reach for arthropod vectors, hosting or carrying viruses.

Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

The purpose of our essay is to investigate the role of the practice period under supervision from a skilled practioner as a part of the student?s development of knowledge. This essay?s main participants are students who are studying their sixth semester during the spring 2009 at the bachelor program of social work at the University of Gothenburg and active skilled practioners during the autumn of 2008 and spring 2009. The essay has primarily a qualitative approach.

This is a case study that explores the ways in which implemented university reforms have affected employees in the higher educational sector. Previous research within the research field has mainly focused on policy related consequences of the reforms. This is why a study that brings attention to the ways the reforms have affected employees is sorely needed.The aim with the study is to examine whether there is a discrepancy between formal changes and the ways the employees experience them. The study is based on interviews with 8 lecturers from two universities and the material is analyzed mainly through sociological neo-institutional theories, such as Richard Scott?s theory of the three pillars within an informal institution and Helmke and Levintskys theory of the relationship between formal and informal institutions.The results show that there is a discrepancy between the formal changes and the ways employees perceive them.

Title Greenlighted employees ? The internal value of Schenker?s environmental work.Author David Fridner.Course Master thesis in Science of Media and Communication.Department of Journalism and Mass Communication, University of Gothenburg.Semester Spring semester 2009.Tutor Professor Monika Djerf-Pierre.Number of pages 55 (appendix 23).Aim The aim is to study the internal value of Schenker?s environmental work.Method Qualitative and quantitative method.Material 20 interviews from four workgroups: managers (4), sales (5), customer-services (4) and truck drivers (7). 148 websurveys from two workgroups: sales (106) and customer-services (42).Main result Schenker is perceived as an environmentally friendly enterprise. Much due to the fact that the company?s impact on nature only has little to do with how the staff evaluate its ?greenness?.

The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

Posttraumatic Stress Disorder (PTSD) is an anxiety disorder resulting from exposure to a traumatic event. The purpose of this study was to examine the exposure to Potentially Traumatic Events (PTE) and the prevalence of PTSD among students at the University of Lund. Sexdifferences among these variables were also examined. Using surveys as research method, 380 students from five different faculties participated. The results indicated that these students have been more exposed to PTE than the general Swedish population.

The purpose of this study was to examine if there were anychanges in quality in the voices of speech and language pathology studentsafter four years of study at the University of Gothenburg. Recordings oftwenty student voices from the first and eight semesters were evaluatedperceptually by six speech-language pathologists. The parameters judgedwere: vocal fry, glottal attacks, strain, breathiness and resonant voice, usinga scale from 0 to 10. Acoustical measures were made of F0 mean andmedian to detect possible differences between the two recordings. Theresults show a significant decrease in vocal fry, glottal attacks and strain aswell as an increase in resonant voice and a significant decrease in F0 meanand median.

Är dykare spänningssökare? Är män mer spänningssökande än kvinnor? 51 dykare, 27 män och 24 kvinnor, läts fylla i enkäten Sensation seeking scale version 5 (SSS-V). Sensation seeking scale har utvecklats av Marvin Zuckerman med kollegor sedan 1960-talet och mäter graden av spänningssökande personlighetsdrag, på engelska: sensation seeking. Enkäten har visat sig valid på flera hundra studier men har bara testats på dykare ett fåtal gånger. Hypoteserna är att dykare är mer spänningssökande än normalpopulationen (H1) och att dykande män är mer spänningssökande än dykande kvinnor (H2).

The purpose of the study was to review the current veterinary literature regarding gastric dilatation and volvulus (GDV) considering pathophysiology and treatment, and to evaluate the operative technique (incisional gastropexy) used during the years 2005 and 2006 at the University Animal Hospital (Universitetsdjursjukhuset), SLU, Uppsala, Sweden. GDV has a complicated pathophysiology which foremost effects the circulatory system. Progress is often acute and it is not unusual that patients are affected with shock. The initial treatment targets to alleviate the shock by fluid therapy and decompression of the stomach. There is a high risk of recurrence in the long term perspective unless the stomach is surgically fixated by gastropexy. The study describes two different techniques for gastropexy; incisional gastropexy, and funduspexy. Long term complications were rare among the patients that were treated surgically, while about half out of the eighteen dogs that undergo surgery do experience complications of various severity in the short term..
