Bovin tuberkulos : smittvägar mellan människa och nötkreatur på den östafrikanska landsbygden
Tuberculosis is one of many infectious diseases in the world and is responsible for a large number of human deaths each year. The cause is Mycobacterium ssp included in the tuberculosis-complex, there among Mycobacterium bovis and Mycobacterium tuberculosis. Infection with M. bovis causes bovine tuberculosis in cattle which in 90 % has a pulmonary location. Humans are infected mainly by milk from infected cows but also by close contact with coughing animals or by eating raw meat.

Ett folkbibliotek och dess användare: användares uppfattningar av service relaterade till verksamhetsintentioner
The aim of this MA thesis is to examine how users regard and receive the services offered by a specific public library. We also examine what the conception of service means to the users and how they perceive this service being offered by the library. We look upon if and to what extent the service conception depends on contact with the library staff. The methods used are qualitative interviews and analyses of documents directing the library activities. The public library we have examined in this respect is the public library of Västerås.
Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs
Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation.
Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Sjuksköterskans upplevelse av att bedriva psykiatrisk omvårdnad : En litteraturstudie
Background: Studies have shown that 66 children and teenagers in Sweden suffers from brain tumor every year. Children and teenagers who can´t participate in the regular school for a longer time for whatever reason, have by the school law the right to education in hospitals or institutions. Education that take place in other places than school most try to follow the same guidelines as his/hers usual school. This applies to students in elementary school, compulsory school, special school, Sami school, secondary school and upper secondary school.Purpose: The purpose of this study was to find out how three teachers at a hospital school plans their work with children in grade from 1 to 3, who suffer from cancer, especially brain tumor. How can the teachers at the hospital school plan and organize their teaching so that it´s possible for the children whit brain tumor to feel as normal as possible. How does the common work between the consultant nurse, teachers at the hospitals and their ordinary school prevent the children to feel like an outsider?Method: I have chosen to do a qualitative study followed by three interviews whit three informants who works at a hospital school.
En studie av sociala faktorer : Som kan medföra problem vid implementering av informationssystem
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.
Produktutveckling och prestandatest av ett vattenvärmedrivet torkskåp : Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
AbstractElectricity consumption is a globally increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high efficiency because they use the residual heat for domestic heating. The CHP plant often use fuels from renewable resources, giving them a lower carbon footprint, but are also depending on the heat demand. If electric powered products such as drying cabinets convert to heat powered products more environmentally friendly electricity will be produced by CHP plants, which can supplant electricity, produced from coal power plants and reduce carbon emissions.

Oljefilmens tjocklek mellan kolvring och cylinderlopp
Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

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.
