EN TOTALKOSTNADSJÄMFÖRELSE MELLAN CELL-, SKUM- OCH LECA-BETONG
This report provides a comparison between the products cellular concrete, foam concrete and LECA concrete. The questions to be answered during the work is how the cellular concrete stands up in cost terms to the existing competitors on the market, how the concrete products differ in design work, and in which situations the concrete varieties are preferred to use.Cellular concrete is a variant of ordinary concrete, with the difference that the ballast is exchanged from stone materials to expanded polystyrene beads (EPS). This substitution gives a product with higher insulation values but lower weight than ordinary concrete.The work was carried out by designing a survey which was sent to two hundred randomly chosen companies across Sweden, to see the building industry?s opinion of the product cellular concrete. The survey showed that cellular concrete was equals its competitors in terms of price, while the product was said to be more flexible, quicker and easier to cast.Then some of the companies, who participated in the survey, were interviewed to see more carefully, how the price, the workmanship and the time for casting and dehydration differed between the products.
Mätning av kranskärlet LAD:s slingrighet : en pilotstudie
The background to this report is the author?s ambition to understand individuals? work situation, how it?s formed in interaction between the individual and factors in the work-setting. Such an ambition is well in line with the concept of Human-Technology-Organization (HTO), a cross-scientific approach that puts a system-oriented perspective on how human, technolog-ical and organizational factors interact within work systems.The aim of this report was to explore managers? work-situation and generate an understanding of it from an HTO-perspective by using an organizational model as a framework for an interview guide and to analyze the work situation from an HTO-perspective following the ques-tions at issue:1. How does the managers experience their work situation?2.

Termisk hantering av litium-jon- batterier i elektriska drivsystem
The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

Fastställande av referensintervall för fibrinogen i plasma hos friska föl :
Establishing a reference interval for plasma fibrinogen in foals
Fibrinogen concentrations were analysed in EDTA preserved blood plasma samples from 34 thoroughbred foals born in 2001 and 2002 at one stud farm. The foals were between 0 and 240 days old at the time of the sampling, and there were 19 fillies and 12 stallions in the group. The foals were examined for clinical symptoms of disease and their body temperature was measured before blood was sampled from the jugular vein. From totally 156 blood samples, 31 were selected as originating from clinically healthy foals, and used to determine a reference range for thoroughbred foals. Samples originating from foals showing clinical symptoms of disease or an abnormal body temperature at the time of sampling, were classified as coming from unhealthy animals.
Oralt skivepitelkarcinom på katt : uppkomst och förekomst
Oralt skivepitelkarcinom är den överlägset vanligast förekommande tumören i munhålan på katt och 10 % av alla tumörer som drabbar djurslaget består av denna cancerform. Lokala infiltrationer är vanliga medan metastasrisken till andra delar av kroppen är relativt låg. En katt som diagnostiserats med sjukdomen har endast 9,5 % chans att överleva en ettårsperiod och även efter behandling är överlevnadschanserna relativt små. Behandling med mandibulaektomi verkar vara den mest effektiva men medför ofta kroniska postoperativa komplikationer som ätsvårigheter, framskjutande tunga, snedvriden underkäke, ökad salivering, svårigheter då katten ska tvätta och slicka sig samt felaktigt bett med skador på gommen som följd. Tumören utvecklas oftast i den mandibulära gingivan eller i de sublinguala delarna av munhålan och mukösa ulcerationer, nekroser och variga inflammationer tillhör de patologiska fynden.
Det är osäkert hur oralt skivepitelkarcinom på katt uppstår men forskningen pekar på att det rör sig om cancerstamceller som driver utvecklingen.
Inverkan av juverhälsostatus på variation i mjölkens sammansättning och innehåll av utvalda inflammatoriska markörer
SAMMANFATTNINGMastit är den vanligaste och mest kostsamma sjukdomen hos mjölkkor. Enligt statistik från Svensk Mjölk har cirka 65 % av alla kor i Sverige mastit någon gång under en laktation. Subklinisk (utan märkbara symtom) mastit utgör det största problemet. De är svåra att upptäcka då även mjölken ser normal ut, vilket resulterar i att den hamnar i tanken och levereras till mejeriet. Mjölk från kor med mastit har ett ökat celltal samt försämrad kvalitet och sammansättning vilket i slutändan medför sämre betalt för lantbrukaren.
Development of new food products with components active against Helicobacter pylori - with purpose to improve gastric health in humans
Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.
Juverinfektion hos tackor med kliniskt friska juver : möjliga riskfaktorer och djurägarattityder
Juverinflammation (mastit), oftast orsakad av en juverinfektion, är en betydelsefull sjukdom hos får och den vanligaste utslagsorsaken hos svenska tackor registrerade i Fåravelförbundets avelsregister. För att kunna förebygga juverinfektion är det viktigt att ha kunskap om riskfaktorer för juverinfektion. Det finns dock få studier som undersökt detta och mer kunskap om riskfaktorer för juverinfektion behövs.
Syftet med denna studie var att försöka undersöka möjliga riskfaktorer för juverinfektion hos svenska tackor med kliniskt friska juver. Vidare var syftet, att med hjälp av en utskickad enkät, undersöka svenska fårägares kunskaper om och attityd till mastit som sjukdom.
Mjölkprover från 753 tackor i 22 svenska kött- och pälsproducerande fårbesättningar togs vid lamning och/eller avvänjning mellan juni 2013 och augusti 2014. Ett protokoll för juverundersökning och tackdata fylldes i för samtliga provtagna tackor.
Metodik för robotsimulering och programmering av bågsvetsrobotar
Det finns flera fördelar med robotiserad bågsvetsning jämfört med manuell bågsvetsning. När det gäller produktivitet och repeterbarhet är robot överlägsen människa, vilket gör att produkterna håller jämnare kvalitet. I slutet av 80-talet började offline-programmering att tillämpas. Att programmera en robot offline innebär att utföra programmeringen med dator utan direkt tillgång till roboten. Genom simulering visualiseras ett robotprogram i en grafisk modell av den fysiska robotcellen utan att den fysiska roboten behöver tas ur produktion.
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.
