Purpose/Aim: The goal of this thesis is to examine access and knowledge computers and the Internet among the senior-year students of Anacostia High School. Do the students of this facility have the same opportunity as the residents from better socioeconomical backgrounds or are they being excluded from the technology? Material/Method: To approach the thesis goal I have used a quantitative method. More specifically, a questionnaire was handed out to the senior year students at Anacostia High School. Main results: The study has shown that most of the students of Anacostia had in some way access to computers and Internet.

This study was performed to investigate the possibility to use ultrasonography as a diagnostic tool for sub-clinical mastitis in dairy cows. Five cows with high cell counts, and four cows with low cell counts were selected as cases and controls, respectively, and their udders examined with ultrasound during a 5 week period. The image of the udders of cows with high cell counts exhibited small, hyper-echoic, rounded foci, approximately 1 cm in diameter, near the milk cisterns and the base of the teats. These changes were not found consistently in all cows with high cell count, however. Ultrasonography may be a valuable complementary tool in the diagnosis of sub-clinical mastitis in dairy cow, but more cases need to be monitored before its full value can be ascertained..

Planet rendering plays an important role in universe visualization and geographic visualization. The recent tools and methods allow better data acquisition, usually with very high resolution. However in computer graphics, there is always the limitation on the resolution of geometry and texture due to numerical imprecision. Not many applications can handle high resolution data effectively.This thesis introduces, Implicit Surface Scene, a level of detail scene management inspired by dynamic coordinate system and SCALEGRAPH? which change over time depending on the current camera position relative to the planet surface.

AimThe purpose with our study has been to investigate if upper secondary high schools in the south of Sweden, Stockholm and north of Sweden follow the outdoor education regulations stated in the curriculum (Lpf-94). Moreover, we aim to study if the teachers? previous experiences as well as the students affect the outdoor education. Finally, the purpose is to find out how the outdoor-life-education can be improved. These are the research questions:o How do the chosen high schools follow the outdoor education regulations stated in Lpf-94?o What obstacles, advantages and differences exist between the outdoor-life-education in these high schools?o In what way do the teachers? outdoor life experiences influence their education at school?o How can the students influence the outdoor education in their High Schools?o How can outdoor education be improved?MethodThe study is based upon data collected from four interviews with PE ( physical education) teachers from four different high schools.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

The purpose of this study was to describe perceived psychosocial work environment and musculoskeletal complaints among baggage handlers, and to evaluate whether there is any linear relationship between them. The study is a questionnaire based cross-sectional study, and part of an ongoing larger project. Therefore, the number of forms has been limited to those that were collected in the project by 2010-11-25 (N=117). The questions analyzed in the study come from the Copenhagen Psychosocial Questionnaire and ?Nordiska Ministerrådets formulär om besvär i rörelseorganen?, respectively.

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

AbstractThe purpose of this work is to try to find out how young people's reading habits among students look at different types of secondary school, ie. both theoretical and practical, and what factors might encourage them to read more. My questions have been; do young people read today? Is there any difference between city, gender or program? What can a teacher do to inspire young people to read more? I have made a questionnaire survey among different students at two different high schools in Skaraborg. The first school is a high school located in a medium sized town, where I made inquiries to the scientific program, social program, Business and Administration Program and the Electricity Program.

The purpose of this study has been to examine different aspects of the professional role of the high school librarian, especially the educational role, and its delimitations to the teacher's role. The methods that were used were studies of literature within the subject area and qualitative interviews with high school librarians and high school teachers of social studies. Andrew Abbot's theory on the system of professions was used in the analysis of the results of the study. The high school librarians who were interviewed enabled access to information, both intellectually and physically. They helped students develop information seeking skills and they functioned as educators and counselors.

Genom konstruktion och tillverkning av prototyper samt med hjälp av ljud- och flödesmätningar av dessa, tillsammans med standardmodellen, har vi lyckats förbättra flödet genom ventilen Al-db 450, producerad av Fresh AB i Gemla. För ljudmätningar har en testrigg konstruerats och tillverkats..

Kundrelationerna i svenska B2C-företag är inte lika goda som de var för 60 år sedan och de är inte lika goda som företagen skulle önska att de var. Forskningsfrågan och syftet med uppsatsen var därför att förklara vad som påverkar svenska B2C-företags beslut att utnyttja Radio Frequency Identification (RFID) som identifieringsteknik för att personliggöra kundrelationer inom sina lojalitetsprogram. Studien utfördes som en fallstudie då vi undersökte hur två stora svenska B2C-företag, IKEA Family och ICA, arbetade med lojalitetsprogram, identifieringstekniker och hur de ställde sig till alternativa identifieringstekniker gestaltat genom RFID. Studien utfördes med deduktiv ansats genom inledande teoriinsamling och därefter genom intervjuer med en intervjuperson på vardera företag. De slutsatser som sedermera kunde dras var att tillräcklig kunskap saknas kring RFID och dess potential, att det är en ekonomisk fråga och en stor investering för företag som inte brukar vara först att ta till sig ny teknik som dessutom inte är standardiserad samt att det skulle kunna kränka kundernas integritet och därmed ha motsatt effekt till lojalitetsprogrammens syfte..

Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

This thesis investigates how the level of implementation of New Public Management affects an organization?s efficiency. According to theory, a high level of implementation leads to a more efficient organization. This thesis is based on two case studies conducted on two units within Stockholms Stad. One of the units shows a high level of implementation of NPM and a high level of efficiency.

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.
