Internrevisioner är ett krav om företag och organisationer är certifierade enligt ISO 9001 eller ISO 14001. Främsta syftet med internrevisioner är enligt Wahlman (2004) att bekräfta att ledningssystemet och de arbetssätt som beskrivs i ledningssystemen ger den önskade effekten. Examensarbetets omfattning är att beskriva och jämföra de två olika metoderna för internrevisioner som finns inom kärnkraftsbranschen. Dessutom ges konkreta förbättringsförslag för de olika internrevisionsmetoderna. De två olika metoderna för internrevisioner har författaren studerat på fallföretaget Ringhals AB som är ett kärnkraftverk.

Mastitis, an inflammation of the udder mainly caused by a bacterial infection, induces an increase in the somatic cell count (SCC) in milk and is consequently one of several factors affecting SCC in milk. In this literature review it is investigated whether SCC; on udder quarter, cow composite or bulk tank milk level, can be used as a quality marker with focus on milk composition in terms of the content of fat, lactose, total protein, casein and whey protein. According to this literature review the relation between SCC and milk composition is not reliable either on udder quarter, cow composite or bulk tank milk level. SCC was related to lactose, casein and whey protein on udder quarter level; lactose and whey protein on cow composite level and lactose on bulk tank milk level.

Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.

This thesis is based on a case study for the real estate manager Mimer in Västerås. Mimer provides a great deal of this city?s rental apartments. Many of their buildings have ventilation systems with a type of heat-recovery called ?heatpipe?.

Denna rapport består av information och data som har samlats in i syfte att kunna presentera en genomförbar konvertering av linfärjan Toras framdrivningssystem, som idag utgörs av dieselelektrisk drift, till bränslecellsdrift. Den bränslecell som behandlas i rapporten är PEMFC och är en bränslecellstyp som drivs av ren vätgas. Resultaten tjänar som en informationskälla för en potentiell konvertering och presenteras för Trafikverket, som ett alternativ i linje med Sveriges regerings mål att reducera mängden CO2 utsläpp på en nationell nivå. Informationen i rapporten har insamlats via mail- och telefonkontakt samt ett besök på Tora på plats i Stockholm. Ett genomförande av konverteringen är fullt möjligt men mer kostsamt än dieseldrift i dagsläget med avseende på höga bränsle- och inköpskostnader utav bränsleceller.

Sport horses are widely used for performance in jumping, dressage, endurance etc. To enable comparisons of horses, training facilities, programs or physical status, an exercise test can be used. Exercise tests are also important to increase knowledge about exercise physiology of the horse considering different ways of training to compare training methods or individual qualities, development of an individual or other investigations of equine exercise physiology. Since several investigations are done on standard- and thoroughbred horses but less on sport horses, it is of great importance to get an overview of the investigations done. Most common is to investigate heart rate and lactate concentration.

The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party.By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data.The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber.

Röntgenläkarna väljer ofta att byta undersökningsteknik för att fastställa misstänkt patologi som inte går att diagnostisera med en metod. Vid röntgenundersökningar av sinus (bihålor) så kan läkaren välja mellan konventionell röntgen eller en datortomografiundersökning. Skälet är att diagnoser som tumör, benpåverkan eller ansiktstrauma inte avbildas lika bra med den konventionella metoden. Syftet med den här studien är att jämföra datotomografi och konventionell röntgen vid sinusundersökningar, vilka för och nackdelar som de olika metoderna har, hur bildinformationen och diagnostiken skiljer sig, vilka risker som finns med joniserad strålning samt vilka biologiska effekter strålningen har på människan. Intervju har gjorts med odontologi läkare som berättat om för och nackdelar med de olika metoderna, och litteratur och artiklar har gett kunskap för att komma fram till resultatet.

Nuclear power production carries potential risks both for the environment and for the work force. Different safety measures are employed and they stem from local rules as well as from regulatory authorities. This work describes the development of a safety promoting tool at Forsmark Power Plant, one of Sweden?s three Nuclear power plants. We describe the development of a computer based system for Pre-Job Briefing and Post-Job Debriefing.

MARIA HEDIN, CIVILINGENJÖRSPROGRAMMET, Ergonomisk design och produktion MARIA MARKLUND, TEKNOLOGIE MAGISTEREXAMEN, Industriell design Examensarbetet har utförts inom programmen Industriell design samt Ergonomisk design och produktion vid Luleå tekniska universitet under en period av 20 veckor i oktober 2006 till februari 2007. Uppgiften var att utveckla koncept för ett lyfthjälpmedel till den MultiTask-cell (MTC) som nyligen installerats i Volvo Aeros produktion i Trollhättan. Cellen består av fem MultiTask-maskiner vilket innebär att varje maskin kan utföra alla nödvändiga operationer (borrning, svarvning, fräsning etc.). I maskinerna bearbetas detaljer till flygmotorer med hjälp av verktyg som till största delen hanteras av industrirobotar. När den bearbetande delen på verktygen ska bytas sker däremot hanteringen manuellt av operatörerna. I MTC:n finns ett område speciellt avsett för byte av den bearbetande delen på verktyg, även kallat ställning av verktyg.

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

Can degree of degenerative brain disease be predicted with the help of measurements of cognitive deterioration?Alzheimer?s disease progresses through nerve cell break down in the brain and the simultaneous deterioration of the individual?s cognitive function. This disease is common among elderly persons. This thesis examines if the level of deterioration of cognitive function is associated with different biochemical and clinical markers for degenerative brain diseases. In addition, this thesis examines if the level of decline in cognitive functions vary between groups with different levels of degenerative brain disease.

Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production.

Today, there are more than 12 000-14 000 farms worldwide using an automatic milking system (AMS). Studies have shown that transition to AMS affects the udder health of cows adversely, recognized primarily as elevated somatic cell counts. There are several reasons for this, for example the greater variation in milking frequency seen in AMS. On one hand, short milking intervals may lead to bad teat condition of the cows due to the stress the milking procedure exposes the teats to. Too long milking intervals, on the other hand, seem to predispose for milk leakage, which is, in turn, a risk factor for the development of mastitis.
