In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review. Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.

E.ON Elnät has in their project Operational Performance developed a priority tool forconstruction and operation. The tool will help the users to increase the capability to prioritybetween new development projects and removal of faults. The tool can be seen as a measuringfor different bay?s reliability, size and the community usefulness. The result of the priority isdirectly connected to which calibration that is chosen in the tool.The priority tool is still under development and there is therefore an uncertainty about howsensitive the tool is for changes in the calibration.

Farmers? main reason for crossbreeding dairy cows is that they have seen a decline in functional traits, especially in the Holstein breed. Throughout crossbreeding, the farmers can combine functional and production traits of different dairy breeds and utilize the heterosis effects which emerge when two or more breeds are crossed. Results from different studies with Holstein crossed with Jersey, Brown Swiss, Normande and Scandinavian Red have shown that the crosses had higher fertility, longer productive life, had fewer stillborn calves and had easier calvings than purebred Holstein. The Holstein crosses have shown very good results and sometimes even better than the purebred Holstein for fat production, which gave higher amount of energy corrected milk (ECM) and higher income for the farmers.

Swedish farmers have the possibility to be subsidized by EU rural development programme for grazing animals on pastures to promote the biodiversity of flora and fauna. The environmental remedy sometimes does not allow supplementary feed and at the same time the Swedish Animal Welfare Act and the Swedish Agricultural Board?s regulations for animal welfare and protection states that animals, in this case horses, shall be fed with food of good quality and adapted for the species. The regulations also state that they should have an individual feeding regime that enables them to maintain a normal body condition. The aim with this master thesis has been to investigate if it is possible to keep Gotland ponies on extensive pastures, during late spring and summer and still maintain animal welfare. The horses were assessed every fourth week using a welfare assessment protocol developed in line with the Welfare Quality® project (submitted, Viksten et al) where physical, behavioural and resourcebased parameters were observed. Twelve one-year old stallions of the breed Gotland ponies purchased from different breeders were used in the study.

The focus of this project has been on the drainage tank of the reheater on Ringhals 1. This tank has on two previous occasions received such a high water level that the system automatically emergency stopped. For this reason, events and various readings from these two occasions has been specifically studied and analyzed. In order to prove theories about what causes these problems a model of the system was created in the program Dymola. Using simulation results from the model, we have been able to demonstrate how the system's measured values should look likeunder normal conditions with respect to flows, pressures, temperatures, valve positions and water level in the drainage tank.

It has in a broader extent become important for companies and other organizations with large organizations to have a properly functioning web platform where content management is an essential part. Polopoly is a web content management system developed in Sweden, used by several European corporations but foremost Scandinavian such working in different media related business areas.Our aim has been to analyze this tool and render a report which hopefully will assist the initiator of our thesis; a consulting enterprise called Qurius, in their negotiations with future customers, when to suggest Polopoly as a suitable content management solution.By using case studies at companies currently using Polopoly, our goal is to define which characteristic makes the product a competitive publishing tool. To put our analysis in perspective, we will compare the most important aspects of Polopoly with a similar product.According to the results of our investigation we consider Polopoly being a beneficial choice with regard to a number of important parameters. Finally we have summarized these properties in a list of examples explaining in which cases Polopoly is a preferable alternative as a web based content management platform..

Med tankar från pedagogen Montessori och filosoferna Platon och Baudrillard har detta arbete behandlat frågor om datorn och dess betydelse för en grafiker. Frågeställningen formulerades efter hand och lydde tillslut: ?Hur kan materia te sig i digital form?? Forskningen resulterade i en hypotes för hur digital materia skulle födas i datorn: genom att blanda två uppsättningar av data, såsom två genuppsättningar tillsammans skapar en ny organism. Under produktionen utvecklades därmed en metod för hur en grafiker ska kunna skapa tillsammans med en dator. Syftet är att ge andra grafiker ett nytt sätt att se på digital grafik.

In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.

The purpose of this paper is for the reader to realise how national innovation systems are deeply intertwined with the legal background of a country and to understand the processes that involves national innovation systems specifically regarding the stem cell / genetics research and how the need for specific community law must be considered targeting the stem cell patents. The legal part will try to answer: Why is it important given the actual state of the European stem cell national innovation systems for the European Commission to take a stand and tackle issues regarding the patenting of the human stem cell innovations? This is done from a country industry analysis (business approach) and then linking it with competition law from a community stand point of view (that tackles biotechnology issues). In order to achieve this the paper is divided into three separate analyses beginning with a theoretical background of general biotechnology / genetic terms that will enable the reader to have a general understanding of the importance of this kind or research ( genetics / stem cell research). The chosen countries case studies exemplify very diverse economies and development perspective from the traditionally R&D intensive to the least and from the biggest countries in Europe to one of the smallest, thus giving cultural, legal, economic and scientific variety..

This master thesis is an in-depth study of an existing heating system at a household cooperative in Uppsala that has been converted from district heating to a bedrock heat pump system. The study focuses on an economical system optimisation of the building?s complete heating system. The aim was to determine how well a heat pump system in large buildings actually work, find out possible ways to optimize the existing system and point out important system parameters for new heat pump installations in larger buildings.The project points out a possible energy cost reduction of 45 % without investment and further cost reductions with equipment investments. A reduction by 30 % is possible by improvements in the regulation system and 15 % is possible by maintaining the brine system.

To make your company change from a conventional workflow to an ICC-based workflow you need tomake investments in time and money. On the other hand you get your reward in terms of a stable andquality safe production. To choose this way of adjusting your company to new routines requires accuracyas well as a great deal of commitment. It is not only about having the right equipment. There area lot of factors that affect the quality of production.Our ambition with this report is to bring out the importance of general thinking when it comes toICC-profiling and to discuss on which basis printing profiles should be created.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

There are two species of potato cyst nematode (PCN), the yellow, Globodera rostochiensis, and the white, Globodera pallida. Each of them can appear in different pathotypes. These are separated by testing the nematode ability to multiply on a number of potato cultivars with different resistance properties. The aim of this project was to examine the virulence of Swedish and foreign PCN populations and to compare two test methods. Biotests are today the only available tests used to study virulence.
