Social behaviour and time budget of breeding bulls
The aim of this study was to investigate the social behaviour and time budget of breedingbulls kept at VikingGenetics, Falkenberg in Sweden when the staff was off duty. It was ofinterest to see if there was any difference between bulls housed in group pens and bullshoused in individual pens. It was also of interest to investigate if there was any differencein the behaviour between the dairy breeds Swedish Red (SR) and Swedish Holstein (SH).Sixteen bulls were used in this study. Eight bulls kept in individual pens and eight bullskept in group pens were used. The individually housed bulls had a social gate with widerbars where the bulls could but their head and neck through to have social contact with thebulls in its neighbouring pens.
Evaluation of tools for analysis and quantification of Fusarium mycotoxins
Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

Intranät från ett användarperspektiv: En fallstudie om hur en grupp bibliotekarier upplever och använder sig av intranät i deras yrkesroll.
This is an investigation into the ways in which a group of librarians experience and make use of the intranet in their vocational role. The theoretical frame of reference consists of a model of how professionals seek information, which is based on a role-theory. As a method, I have applied a qualitative case-study. Using semi-structured qualitative interviews I have interviewed five librarians and the webmaster responsible for the intranet in their library. I have investigated how elements such as the age and vocational role of the librarians affect their use of the intranet.
Driva tulpaner i näringslösning eller i jord :
The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands.
There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
När LSS krockar med AML : Enhetschefers upplevelser av åtskilda rättighetslagstiftningar som möts inom utförandet av personlig assistans
The aim of this study was to examine how heads of unit in charge of personal assistance (PA)for the disabled experience and handle ethical dilemmas and situations within theirworkgroups when The Work Environment Act and The Swedish Act Concerning Support andService for Persons with Certain Functional Impairments collide with each other. The methodof the study was to use semi-structured interviews based around three main topics; the head ofunits opinions about the value and purpose of The Work Environment Act in theadministering and implementation of personal assistance services, the problem solvingprocess and the head of units own individual experiences of ethical dilemmas or workenvironment-related conflicts or situations within their workgroups. Four heads of unit wereinterviewed for this study. The results of this study showed that the interviewed heads of unitexperienced a lack of clear and factual information about how they were meant to solvedilemmas emerging from the two laws conflicting with each other regarding the rights of thecare recipient to layout their personal assistance to their liking, versus the rights of thepersonal assistant to have acceptable working conditions. The heads of unit could not rely onlegislation and/or other specific directive documents when work environment-relatedproblems arose.
Är tiden inne för virtual reality i hemmet? - En experimentell studie av virtual reality med 3D och head tracking
Genom åren har intresset för och satsningar på underhållning i tredimensionellt format (3D) gått i vågor. Idag har de flesta biografer stöd för att visa 3D-filmer. Utöver detta intresse har det på senare år även börjat komma mer teknik för 3D i hemmet. Det har också introducerats många nya mer immersiva och intuitiva inmatnings-enheter som bidrar till under-hållning med element av virtual reality hemma. Företagen Sony, Nintendo och Microsoft har alla lanserat olika typer av avancerade tekniker för sådana inmatnings-enheter till sina spel-system.

Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64
The report comprises two separate parts:part 1: Temperature needs for district heating in the paint shop for axles in building 210part 2: Energy and low temperature waste heat solutions in heating and cooling systems for building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
Salmonella prevalence in the poultry feed industry in Pakistan
Abstract
One of the leading causes of food borne infections in the world is due to Salmonella by con-suming poultry products including eggs and meat. According to US Food and Drug Admin-istration (2009), 2 to 4 million cases of Salmonellosis in humans occur every year only in US. Salmonella causes wide range of diseases with enteric and typhoid fever, food poisoning, di-arrhea and gastro-enteritis. Many serotypes of Salmonella do not have host specificity and cause disease in all kinds of animals and humans. Salmonella has capability to modify accord-ing to the changing environment and it can develop resistance against routine elimination practices of sanitation, chemical treatments and antibacterial drugs.
Newly established poultry industries in Pakistan are confronting various infectious diseases including Salmonellosis while in Sweden Salmonella prevalence in animal products con-sumed for humans is extremely low.
Oljetemperaturens inverkan på motoroljans degradering i lastbil
The market for heavy duty engines is constantly requiring engines that should be more andmore powerful, while still maintaining low fuel consumption. As a result of increasing enginepower, the engine and coolant temperature increases as well due to insufficient coolingperformance (because of design issues, cost etc.).Also, emission legislations, both current and future, require more and more measures to betaken by engine manufacturers. One way of meeting the legislations is the use of cooled EGR(Exhaust Gas Recirculation), which also lead to increased coolant temperatures.Both these factors also naturally lead to increased engine oil temperatures, the consequencesof which are not thoroughly investigated.This thesis project aims to investigate effects of high temperatures on engine oil degradation,with focus on the greatest degradation process: oxidation. To do this several engine runs havebeen performed on a 310 hp engine with EGR to see what happens to the engine oil in a realengine when exposed to high temperatures. During the tests oil samples have been taken andanalysed for important parameters.As a complement to these engine tests some laboratory oxidation testing have also beenperformed, to be able to compare engine test data with laboratory tests.One goal of the project was to try to formulate an empirical oxidation model, which would beable to predict oil oxidation levels in an engine, given any running parameters.
Några rektorers syn på specialpedagoguppdraget
SAMMANFATTNING:
Månsson, Paula & Jönsson, Lars-Gunnar (2011). Några rektorers syn på
specialpedagoguppdraget ? Vad förväntar sig rektorer i grundskolan av
specialpedagoger? Some head masters views on special education mandate ? What do
head masters in primary and secondary schools expect from special educators?
Skolutveckling och ledarskap, Specialpedagogik, Lärarutbildningen, Malmö högskola.
I detta forskningsarbete vill vi undersöka hur väl specialpedagogprogrammets
examensordning överensstämmer med de förväntningar som finns på vår kommande
yrkesprofession bland rektorer ute på skolorna.
Vi vill belysa detta från rektorers synvinkel eftersom det är de som anställer oss
blivande specialpedagoger. Detta gör vi genom att tillfråga 50 slumpvis utvalda rektorer
i Sverige. Det är våra tolkningar av de 25 inkomna svaren som ger oss en bild av hur
rektorer ser på specialpedagogisk verksamhet.
Vi sände ut en onlineenkät där rektorerna svarade på frågor om verksamheten,
verksamhetens syn på elever i behov av särskilt stöd samt specialpedagogiska insatser.
Frågeområden som vi anser ringar in vårt problemområde på ett relevant sätt.
Undersökningen visade att rektorerna anser att den specialpedagogiska verksamheten är
viktig men då budgeten är för snäv blir denna verksamhet lidande.
Modern virtual reality
Målet med detta projektet var att se hur långt vi kunde ta virtual reality med hjälp av moderna tekniker och ideer. Detta genom att kombinera traditionell virtual reality med en Head Mounted Display samt headtracking, sedan lägga till relativ positionering. Sammantaget skulle det ge en helt ny spelupplevelse med dig som spelare i centrum. Genom att titta på andra projekt ska vi undvika att göra om deras misstag. Sedan var vårat huvudmål att utvärdera människans reaktion på en virituell verklighet..
