Riskfaktorer för Staphylococcus aureus i mjölk och på has hos mjölkkor :
Mastitis is the most common disease of dairy cows. Mastitis can be painful for the dairy cow and causes economical losses for the farmer. These losses are due to decreased milk production, more working hours for the farmer, treatment costs and possible costs due to culling of the cow. The udder inflammation, mastitis, is often caused by bacteria infection. One of the most common bacteria found to cause mastitis in Sweden is Staphylococcus aureus (S.
Ändamålsanpassad TINA-sortering av sågtimmer :
Swedish sawmills of today suffer from unsatisfying economy with high costs and low
benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner.
Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way
gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are
mainly manual but can in some rare cases be automatic.

This essay will connect population changes with land use.
Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess
This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
Informationssystem för service av truckar och städmaskiner
This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided.
Följdeffekter av olika användningssätt för vedråvara : en ekonomisk studie
Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased.
As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.
Prognostisering av aktieavkastningar med hjälp av makroekonomiska variabler - en svensk studie
Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.
Gåpall : Ett produktkoncept

The product aims tosatisfy the demands and needs of the target group called theon the go parent. Trends, qualityand purchase power are features that characterize this particular target group.The project resulted in a walking stool namedBRIO Circus after its source of inspiration.
Genflödet från genetiskt modifierade grödor till vilda populationer
Tillämpningen av genetiskt modifierade (GM) grödor har varit utbredd över hela världen och har ökat markant sedan den första GM-grödan blev tillgänglig för kommersiellt bruk 1996. Sedan starten har det tillkommit mycket forskning kring risken för spridning av transgener från grödor till vilda populationer. För att en transgen ska kunna etableras i en vild population så måste tidiga generationer av hybrider överleva för att kunna återkorsas upprepade gånger med den vilda arten, det gör att det genetiska materialet från grödan succesivt reduceras i varje generation tills det att transgenen är det enda DNA från grödan kvar hos avkomman. För att denna process ska vara stabil krävs det en stark selektion för transgenen. Det här sättet för en gen att etableras i en population kallas för introgression och tros ha spelat en stor roll i växternas evolution.
Demokratins förutsättningar i Västafrika : En jämförande studie av Ghana och Guinea
In subsequent to Post-colonialism the African nations have dilated into different political directions. While some nations have established well-functioning democracies, others are still under authoritarian regimes. The aim of this thesis is to examine if civil society has an impact on democratic development in West Africa. Therefore the theoretical starting point is Putnam?s theory of social capital, but this study will also examine other possible causal explanations for democratic transition.This study will be based on a comparative analysis of Ghana and Guinea.
Fyraåringars kostvanor och fysiska aktivitet
Övervikt och fetma bland barn är ett snabbt växande hälsoproblem i västvärlden, problemet är bland annat minskad fysisk aktivitet och kost med ett stort fett- och sockerinnehåll Den som varit överviktig som barn kan i större utsträckning få hälsoproblem i vuxen ålder Eftersom detta grundläggs redan i barndomen har distriktssköterskan på barnavårdscentralen en viktig roll att fylla. För att distriktssköterskan skall kunna hjälpa och stötta familjen bör de veta hur fyråringar äter och hur de rör sig. De Svenska näringsrekommendationerna kan vara stöd i samtal med föräldrar. Syftet var att kartlägga fyraåringars kostvanor och fysiska aktivitet och undersöka samband i en regional population i Mellansverige. Kostvanorna hos den regionala populationen av fyraåringar jämfördes med kostvanor hos en nationell population fyraåringar.
Behaviour and throughput of dairy cows when entering and exiting two types of parallel rotaries
Today a trend can be seen towards fewer dairy farms and increasing number of cows per farm. Larger farms set a higher demand of more labour efficient milking systems. The time to enter and exit milking rotary platforms is crucial to maintain a high cow throughput. This study is a project initiated by DeLaval in order to evaluate the cow throughput and cow behaviour during entry and exit in two types of parallel external rotaries with different bail designs. The two rotaries compared were DeLaval parallel rotary PR2100 and PR3100HD.
Sensory studies of an energy dense drink for elderly people
The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition.
Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health
care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious
foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly
consumers as a strategy to prevent malnutrition among elderly.
