This report reflects an examination work performed for Getrag All Wheel Drive AB during the spring of 2005. Among the companies range of products there exists some concern regarding the amount of clamping force and friction on bolted joints caused by the assembly torque.The aim of this project has been to determine if there is a simple way in which to identify and then practically apply testing methods for clamping force and friction through utilization of existing testing equipment.Three separate methods of clamping force and friction determination have been tested in rear drive unit, RDU, at a 30 Nm assembly torque. A fourth and final method, screw elongation with ultrasound, has been used as reference. The methods are:?Torque-Tension test.?Screw elongation with micrometer.?Joint stiffness test.?Screw elongation with ultra sound for reference.The results from tests can be viewed in table below.MethodTorque-TensionMicrometerCs=318 kN/mm Assembled with torque wrenchMicrometerCs=318 kN/mm Assembled on lineUltra-soundCS=311 kN/mm Ultra- soundCS=318 kN/mm Joint stiffnessTheoreticalClamping force-21,8 kN17,6 kN17,3 kN17,6 kN17,1 kN17,3 kNFriction-0,110,1470,1530,1470,1520,149.

Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.

The main purposes of this study were to 1) quantify bacterial production in winter during ice conditions, and 2) to compare these production measures with values measured from summer and open water conditions in three humic lakes situated in northern Sweden. Another purpose of this study was to 3) examine whether clear-cutting significantly affected bacterial production or water chemistry in two lakes situated in catchments were a large part of the forest had been removed through logging compared to an undisturbed reference lake. In winter (March/April 2014), the bacterial production ranged from 0, 7 - 2, 2 µgC/L/day and in the summer of 2013 the production values was 4 ? 10 times higher. The main reason for lower bacterial production in winter was ascribed to lower water temperatures as well as to older and more recalcitrant DOC, as there were no significant differences in total dissolved nitrogen or DOC concentration or -quality, that could explain a lower production compared to summer.

This thesis has been carried out in New Zealand in collaboration with the University of Waikato. In association with Dr. Mike Duke the purpose of this work is to investigate whether two different software for modeling of photovoltaic systems are useful in the teaching of solar energy.The next ten years grid-connected photovoltaic systems are assumed to increase and therefore also a rising demand for people with engineering knowledge are to be predicted. For engineer students with a focus on solar energy a more practical teaching with design software´s can be a good method to make the students comprehend more when it comes to large scale photovoltaic systems and be more prepared for working life.The software´s used is called Transient System Simulation (TRNSYS) and Photovoltaic Systems (PVSYST) which are both well used throughout the world. To assess the reliability of the software´s, a reference solar power plant at 16.1 kWp installed capacity are used, which consists of photovoltaic modules from four different manufacturers.

Formulation and testing of a new type of chainsaw lubricantThe company Agro Oil has come up with the idea of developing an environmentally adapted chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have been investigated. Desired viscosity and price are determined for different formulations. The new lubricants tested show lower pour points than almost all products on the Swedish market.A test equipment has been developed to investigate the wear.

Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.

Det här är en kvantitativ studie av hur kreditpreferenser hos mikrobolag med en årsomsättning om mindre än 10 miljoner SEK beror av branschtillhörighet och företagsstorlek. Mikrobolag är små bolag med mindre än 10 personer anställda och en årsomsättning på mindre än 2 miljoner euro. Det teoretiska ramverket utgår från asymmetrisk informationsteori och mer specifikt från pecking order theory, POT samt trade off-teorin. Kreditpreferenserna mäts genom två olika parametrar, dels genom mikrobolagens avsättning till periodiseringsfonder vilket kan ses som ett mellanting mellan extern och intern finansiering, dels genom förekomsten av externa lån från kreditinstitut. Branscherna som undersöks är tillverkning samt tjänster vilka anses skilja sig åt vad gäller kreditpreferenser.

The purpose of this master?s thesis is to study an electronic reference service from a user perspective. By qualitative interviews with eight students the thesis examines their information behaviour, why and when they use the service, the user?s experiences of the service and the communication with the librarian. The users have all used the Swedish electronic reference service Fråga biblioteket ? Forskningsbibliotek.

Internet has made information more easy to get, but also more difficult to retrieve. There is a need for information retrieval systems that assure accurate, reliable and up to date information. Quite a number of both commercial and non commercial search services has been developed on the Internet. We have made a qualitative study of one for-pay product in particular, NetS k, produced by BTJ (Bibliotekstj nst), Lund. It is a database that contains collected, evaluated and classified links, and is especially developed to suit public librarians in Sweden.

Svenska banker har genomgått flera finanskriser som resulterat i olika konsekvenser, bland annat kreditförluster. Intresset för varför en del banker drabbades mer medan andra drabbades mindre påverkade valet av problemområde. Många studier har gjorts beträffande kreditbeslut vid nya krediter, dock verkade området kring kredituppföljningen, det sekundära kreditbeslutet, vara relativt outforskat. Förhoppningen var att kunna bidra med kunskap som dels kunde vara användbar för kreditgivare, genom att dra lärdom av bra exempel, och dels vara brukbar för låntagarna. En annan önskan var att ge inspiration till ytterligare studier i ett relativt outforskat område.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

The aim of this thesis is to examine how different kinds of information seekers are evaluating information quality in the information flow online. To address the problem stated, qualitative interviews were carried out with a librarian as a reference person and a group consisting of journalists and scientists. The result of the study implies that the reference person is well aware of the strategies employed by her in the search process. However, the respondents are not aware of the strategies they are actually using. An explanation is the respondents lack of education in information seeking.
