This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

Progesteron har många fysiologiska effekter, vilka främst syftar till bevarad dräktighet. Tikens reproduktionscykel är unik genom att hon tidvis påverkas av långvarigt höga halter progesteron även om hon inte är dräktig. Det här arbetet fokuserar på hur progesteronets effekter kan orsaka problem hos den icke-dräktiga tiken genom att bidra till uppkomst av pyometra. Man har experimentellt kunnat inducera pyometra genom tillförsel av progesteron, vilket tyder på att effekten av progesteron är en viktig del i etiologin för tillståndet. Progesteron har visats dämpa immunförsvaret genom att förhindra uppkomsten av ett Th1-svar och således även den cellmedierade immuniteten, samt orsaka en förskjutning mot ett Th2-svar. Progesteron har även visats sänka förmågan hos immunförsvarsceller att svara mot bakteriella agens.

Atopisk dermatit hos hund (CAD) är en kliande hudsjukdom med komplex patogenes som involverar felreglering av immunförsvaret, allergisk sensibilisering, defekter i hudbarriären, mikrobiell kolonisation samt olika miljöfaktorer. Dock är den inbördes relationen mellan dessa faktorer inte klargjord. En ökad förståelse för sjukdomens patogenes, bland annat den immunologiska bakgrunden inklusive vilken T-cells- och cytokinprofil som kännetecknar sjukdomen, skulle kunna öka drabbade hundars livskvalitet genom förbättrade behandlingsmetoder. Studier har undersökt cellinfiltrat och visat att både CD4+ och CD8+ T-celler förekommer i ökade mängder i huden hos AD-hundar, och således att det finns Th-celler samt CTLs och/eller suppressoriska T-celler i denna hud. Dessa studier hittade också förhöjda CD4/CD8-kvoter, vilket visar på en ökad lymfocytreaktivitet.

Introduction: More and more children and young people get the diagnosis celiac disease established. Celiac is a life-long disease, which means that the child during the rest of its life has to be on a strictly gluten-free diet. There are few studies so far, which have examined how children having a life-long disease with food treatment and increasing prevalence really experience their health related quality of life (HRQoL).Purpose: The purpose of the study was to examine how children (8 ? 18 years old) suffering from celiac valued their HRQoL and to illustrate as well whether the age of the child and its extent of disease when it was taken ill affected the child?s evaluation of HRQoL later in life. The purpose was also to compare whether the children?s parents valued the HRQoL of their children to the same extent as the children did.Method: 160 children, 54 boys and 102 girls were included in the study.

The objective of this work was to evaluate and compare three field methods for detection of mastitis, California Mastits Test (CMT), DeLaval cell counter DCC (DCC) and FMA2001 Farm Milk Analyzer (FMA2001). Furthermore, to investigate at what cell count level clinical symptoms of mastitis are seen, and finally to check if the clinical findings and cell counts could be related to bacteriological findings. DCC and FMA2001 are new analytic instruments to be used on dairy farms for detection of mastitis. CMT has been a widely used cow-side-test of milk quality in mastitis control efforts, but it cannot be used for estimating cell counts in scientific studies or investigations. Two hundred and eight quarter milk samples from 52 cows were analysed with DCC and CMT, and 168 of these samples with FMA2001. Microbiological examination was done on 38 milk samples with CMT scores of 4 and 5.

Helsädesensilage är en benämning som omfattar ensilage av hela spannmålplantor och/ eller baljväxter. Helsäd av spannmål är i många avseenden ett användbart fodermedel. På grund av att det bara skördas en gång per år kan maskin och arbetskostnader hållas nere. Spannmål går dessutom att så ihop med vall eller som efterföljande gröda i växtföljden och innebär därför inget merarbete för att få det att fungera odlingsmässigt. Vid utfodring av helsäd till mjölkkor och växande nötkreatur behöver näringsvärdet och hållbarheten tas i beräkning.

Svansbitning är ett stort problem i slaktsvinsproduktionen ur såväl djurvälfärdsmässig som ekonomisk synvinkel. Etiologin bakom problemet anses vara multifaktoriell och är ej helt utredd. Man kan dela in faktorerna i interna riskfaktorer och externa riskfaktorer. De interna riskfaktorerna avser genetiska egenskaper med avseende på ras och härstamning, beteende, rangordning, kön, exteriör, vikt, ålder och allmän hälsostatus. De externa riskfaktorerna avser faktorer i miljön, som beläggningsgrad, möjlighet att böka, berikning i miljön, strömaterial, temperatur, ventilation, ljus, säsong på året, boxens utformning, utfodringssystem och fodrets sammansättning. Detta är en retrospektiv studie där prevalensen svansbitningar i en slaktsvinsbesättning har jämförts före och efter en ändring i utfodringsrutiner.

Sweden?s forestry legislation was updated in 2010 and a new definition of forest land was introduced. This definition was adapted to the one used by the Food and Agriculture Organization of the United Nations (FAO) for international statistics on the state of the world's forests. It is in short based on the lands ability to grow forest that reaches 5 meters, 10 % canopy closure and has a continuous distribution, according to FAO at least 0.5 hectares. A country-wide laser scanning is now carried out for the production of a new national elevation model; the laser data also provides information on forest height and density.

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

The background to this work was to see if there was a connection between large woody debris (LWD) and the presence of brown trout in our Swedish forest streams. Previous researches by Degerman et al. (2004) have shown that there is a strong correlation between the amount of dead wood and the presence of brown trout. The goal was then to find a way to restore, maintain and increase the trout habitats by constructing and adding manmade wooden structures that would mimic natural deadwood and its features in flowing water. The inspiration was partially taken from a water restoration program in the Klamath River of northern California, USA.

Discourse Analysis of editorials from Danish and Pakistani newspapers related to 'Cartoon Controversy'. The study examines the intercultural dimensions of media ethics, focusing on the meaning of freedom of speech and CSR as it is perceived by the journalists in the respective contexts.

There is an ongoing evolution in scholarly communication. The traditional way of communicating scholarly results through scientific journals is beginning to be replaced by other means of dissemination. One new channel for scholars to communicate their results is digital publication in so-called open archives. An open archive is a kind of full text database, where a scholar may archive/publish his or her articles, as a complement or a substitute to publishing in scientific journals. There are discipline-oriented archives and institutional archives.

One of the most important components of a harvester is the crane. Most harvester cranes are only possible to pivot (or horizontally rotate) at the crane pillar. Cranab in Vindeln, Sweden, has developed a new type of harvester crane which has an extra pivot point on the outer boom. This makes it possible to reach around residual trees, easing thinning work in dense stands. The aim of the study was to analyze if the use of a pivoting outer boom (POB) crane gave an increase in thinning production and if there were any differences in time consumption between the work elements for the POB crane and a conventional crane. A Valmet 911.3 equipped with a POB crane was used in the study.

The emerging Swedish suburbs of the 1960- 1970s started out as a utopian vision: a new city for the modern people. Media presented a different view and emphasized the inhuman livingenvironment and the social problems of the suburbs. Nationwide there have been local attempts to avoid this negative publicity by adjusting identified suburban problems. Due to medial presentation the suburbs are still associated with segregation, criminality and social problems. The presentation of suburbs and immigrants affects not only the process of integration and the general public idea of integration processes, but also the individual perception of themselves and their living.
