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.

Da?rfo?r vill man ligga i framkant na?r det ga?ller att underso?ka nya tekniker som kan fo?rba?ttra plattformarna och go?ra dem mer tidsenliga. BBM har bland annat velat ta fram ett rekommendationssystem som ska anva?ndas till att go?ra inneha?llet individanpassat pa? webbplatserna och pa? ett effektivt sa?tt presentera detta sa? att de olika ma?lgrupperna fa?r den information de fo?rva?ntar sig.

The purpose of this study is to describe melanotic tumours and the pathogenesis of these tumours. The focus of this study is on differences between benign and malignant tumours as well as the prognosis one may expect when diagnosing this disease. The mechanisms responsible for the occurrences of the tumours are not yet fully understood. It is believed that factors such as chronic trauma, infections, medications and hormones affect the cell mechanisms in some way. Determinants of the malignancy of the tumour are not completely known.

Det är idag mellan 700 ? 800 patienter som väntar på ett nytt organ i Sverige. Dock är tillgången på organ betydligt mindre än efterfrågan, vilket leder till att väntan på ett nytt organ kan bli mycket lång. För en del patienter orkar inte kroppen med den långa väntan vilket leder till en för tidig död. Att vänta på ett nytt organ innebär ett stort lidande för patienten.

Syftet med denna litteraturstudie var att beskriva upplevelser hos levertransplanterade patienter. Metod: En systematisk litteraturstudie där artiklarna är sökta i databasernaElin@Dalarna, Blackwell Synergy, EBSCO Host, CINAHL (EBSCO), PubMed, Wiley, inter Science. Sammanlagt analyserades 15 artiklar. Både kvalitativa och kvantitativa vetenskapliga artiklar ingick. Artiklarna kvalitetsgranskades med hjälp av granskningsmallar och de artiklar som var av hög eller medelhög kvalitet inkluderades.Resultat: Detta resulterade i tio kategorier; känslan av hopp och glädje samt oro, känslan avatt förlora kontrollen, tacksamhetskänsla, identitet, stöd och trygghet i återhämtningsprocessen, relation till andra och sig själv, plågsam smärta, emotionellt och fysiskt välbefinnande,önskan om att återgå till det normala livet och upplevelser av sjukvårdspersonalensstöd.

Denna projektrapport är avsedd att vara ett hjälpmedel för SiCell, en del av SciLifeLab Uppsala som ska bli Europas första plattform för enkelcellgenomik till hösten 2013. SiCell har bett projektgruppen om undersökningar gällande ett Laboratory Information Management System, LIMS. På svenska ett datahanteringsystem för laboratorier. Ett sådant system skulle kunna effektivisera SiCells verksamhet. Undersökningarna har resulterat i en kravspecifikation som ett LIMS för SiCell ska uppfylla och en sammanställning av tillgängliga mjukvaror som bäst uppfyller dessa krav.

A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.

In this bachelor thesis, diagnostic methods for one of Siemens stem inlet control valves have been developed. The work has taken place during ten weeks at Siemens Industrial Turbomachinery AB in Finspång. The company produce steam- and gas turbines and also provides service and maintenance. The purpose with this project has been to develop diagnostic methods that oversee the health of the control valves. By using the developed methods you will know when it?s time for maintenance.

The effectiveness of communication in the Swedish healthcare system context has long been the subject of debate. Issues stemming from usability, accessability and interpretation affect the lives of patients, and yet the vocal groups in the healthcare communication debate are patients and administrators, not healthcare professionals. With the advent of eHealth services and new demands being put forth on the ability of healthcare professionals' to handle increasingly numerous and innovative systems, it is of more importance than ever to understand the healthcare professionals' work context. This article is based on interviews with five healthcare professionals concerning their views on electronic health records (EHR), eHealth services, trends in healthcare services development in Sweden, as well as their views on the future of eHealth solutions and health information technology (HIT). Analysis of collected information shows an apprehension among healthcare professionals towards electronic communication, as well as a dissatisfaction with the usability of modern healthcare systems.

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

Mastocytom är den vanligaste typen av kutana tumörer som ses hos hundar, och utgör 7-21 % av hundens alla hudtumörer. Majoriteten av alla mastocytom hos hundar uppstår i dermis eller i subkutan vävnad. Etiologin bakom uppkomsten av kutana mastocytom hos hundar är fortfarande inte helt klarlagd, och den är förmodligen multifaktoriell. Syftet med den här litteraturstudien är att diskutera olika mekanismer som kan ligga bakom utvecklingen av kutana mastocytom hos hund. Studien tar även upp frågan om det finns en genetisk predisponering hos vissa hundraser. Mastceller härstammar från hematopoetiska stamceller.

Stump treatment today requires large quantities of clean water mixed with the protective product Rotstop, to fully cover the stump surface. In order to reduce the water consumption without reducing the coverage of the stump surface, the pressure in the stump treatment device can be increased. Therefore, the Phlebiopsis gigantea (Fr.) Jül. suspension used as a biological control agent to prevent Heterobasidion annosum (Fr.) Bref. infection was pressure-tested.

Feline odontoclastic resorptive lesion (FORL) is a tooth disease affecting both domestic and wild cats. Although FORL was described as early as the 1920´s, the etiology is still unclear. Several hypotheses have been presented but different studies have obtained contradictory results, and today there is no generally accepted etiology. Teeth affected by FORL are characterized by root resorption with progressive destruction of the tooth structure and alveolar bone as a consequence of clast cell activity. The disease is considered very painful when reaching a certain stage.

In this study, the effects of using fine milled cassava stems as an additive in biofuel pellet production was compared to the effects of refined starch addition. The bulk biomass fuel raw material, to which the additive was added, was a blend of spruce and pine sawdust. An experimental design in the factors cassava/starch content, moisture content and material temperature was used. Measured responses were pellet bulk density, pellet durability, amount of fines, pelletizer motor current, pellet temperature, die temperature and CV for pelletizer motor current (a measure of process stability). Each response was modeled by multiple linear regression (MLR).
