Bogsår hos digivande suggor: inverkan av strategisk halmning och hull
The objectives of this Experimental study were to investigate if a strategic method to supply loose housed sows with large quantities of straw 2 days before expected farrowing and if the sow?s body condition had any effect on the occurrence of shoulder lesions 5 weeks after farrowing. Data came from a study conducted on four commercial piglet-producing farms in southwest Sweden between March and December 2009. At each farm one batch of sows was followed during two consecutive lactations. The sows were randomly assigned to two different treatment groups and the sows that remained in the batch during the second lactation switched treatment group.
A Brief Moment Of Peace. Ett utforskande i visuellt uttryck inom 3d-grafik och animerad film
This project was about the creation of a shorter computer animated film. Thegoal of the project was to explore a different technique of the visual outcomethat should not rely on photorealistic rendering and how to find new interestingways to use 3d-graphic for visuals. A big part of the project was also toincorporate music to create a chosen atmosphere and impact on the viewer butalso to help the story forward and questions such as; ?How can you create anexpression for the feeling you want to transmit?? were formulated. The scenewas built up in a 3d-application consisting of a house and surrounding garden,which within an character was animated to tell the plot.
Seroprevalence of Rift Valley fever in domestic sheep and goats of Gaza province, Mozambique
Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.
Formuleringens betydelse vid intervjuer av utgruppsmedlemmar - kan bristande diagnosticitet leda till diskriminering?
Vilken betydelse har en arbetssökandes etnicitet och beslutsunderlagets diagnosticitet (informationskvalitet) för en granskarens benägenhet att rekommendera anställning? 172 studenter fick läsa en utskrift från en anställningsintervju och skatta hur pass anställbar den arbetssökande (svensk eller utländsk) var utifrån den information som erhölls (diagnostisk eller ickediagnostisk). Hypotesen om att sämre information om den sökandes personlighetsegenskaper medför lägre skattad anställningslämplighet för sökande med invandrarbakgrund (p.g.a. av negativa stereotyper) men inte för svenskar kunde inte bekräftas. Tvärtom skattades den utländske sökanden som mer anställbar än den svenske när informationen var ickediagnostisk (p = .03).
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
Stärkelsenedbrytningens betydelse för mjölkkors konsumtionsmönster och mjölkproduktion :
Feed intake in dairy cows is regulated by a variety of factors influencing hunger and satiety.
One of the regulation systems includes the short chain fatty acids produced during feed
degradation in the rumen. Starch can be digested either in the rumen where short chain fatty
acids are produced or in the small intestine where glucose is the end product. Since glucose
does not have the same effect on satiety that short chain fatty acids have, the site of starch
digestion might be an important factor that affects feed intake and milk production. The aim
of this study was to investigate the effects of site of starch digestion on feeding behaviour
(feed intake, consumption time, and eating frequency) and milk production.
Because feeding behaviour is closely connected to the cows? environment, the study also
included observations of behaviour.
Three different feed rations were compared.
Träning med mål och coachning för patienter med knäartros
Aim: To investigate if physical exercise in combination with coaching will reduce pain and improve knee function in patients with mild to moderate osteoarthritis in the knee compared to physical exercise alone.Method: The study consisted of 42 patients who were randomized to either an intervention group or a control group. Both groups followed a standardized training program at home, but the intervention group received additional support with regard to the aim of their training, as well as extra coaching during the training period of ten weeks. A Visual Analog Scale (VAS) was used to evaluate the patients? pain. A 10 metre walking test, the Index of Muscle Function (IMF) and the Knee injury and Osteoarthritis Outcome Score (KOOS) were also used to evaluate knee function.
Cross-Language Information Retrieval: En granskning av tre översättningsmetoder använda i experimentell CLIR-forskning.
The purpose of this paper is to examine the three main translation methods used in experimental Cross-language Information Retrieval CLIR research today, namely translation using either machine-readable dictionaries, machine translation systems or corpus-based methods. Working notes from research groups participating in the Text Retrieval Conference TREC and the Cross-Language Evaluation Forum CLEF between 1997 and 2000 have provided the main source material used to discuss the possible advantages and drawbacks that each method presents. It appears that all three approaches have their pros and cons, and because the different researchers tend to favour their own chosen method, it is not possible to establish a "winner approach" to CLIR translation by studying the working notes alone. One should remember however that the present interest in cross-language-applications of information retrieval has arisen as late as in the 1990s, and thus the research is yet in its early stages. The methods discussed in this paper may well be improved, or perhaps replaced by others in the future..
Om att skapa en databas över Enaforsholms fjällträdgårds 60-åriga växtförsök
Enaforsholms mountain garden is situated in the western parts of the Swedish province Jämtland. This means a maritime climate. After a donation made by wholesaler A. W. Bergsten the country estate became KSLA property in 1937.
Mjölkningsfrekvensens inverkan på mjölkfettets kvalitet :
The milk production has developed rapidly the last years. The milk production per cow is increasing and the production units are larger with an increasing number of animals and a decreasing number of workers. Many milk producers invest in automatic milking systems (AM) to meet this change. In these systems the cows can voluntary decide milking frequency and usually the milking frequency are higher than two times per day. But how does the milking frequency effect the composition of the milk?
The aim of the present study was to study the effect of milking frequency on the milk composition and the milk fat quality.
Deltack, Blanket Study
There are two objectives of this study.The first one was to study the new instrument Deltack fromPrufbau, and with the new knowledge, study the interaction between blanket and paper.Deltack is a new instrument to measure the ink splitting force. Blankets from an earlier study doneby GATF have been montered on 12 different Deltack print forms and those have together with Deltackbeen the base for this project.This study together with information from GATF?s study shows that some of the blankets have ahigher capability to adsorb ink. Those blankets generate a sharper shape on the force curve, they havea lower dot gain, but they print not as good solid..

Arbetsbelastning hos flygledare: utveckling av belastningsenkät för flygledningsarbete på mindre flygplatser.
In this thesis, it is investigated if it is possible to create a common factor of the work tasks done by an air traffic controller, which then can measure workload. This will lead to the development of a tool to measure workload at small airports. In the research project a questionnaire is created to measure the different tasks an air traffic controller has. The same questionnaire will also measure the number of environmental factors that exists around the air traffic controller. To measure the validity of the questionnaire, the authors are using NASA-TLX.
