Optimering av driftläggningar i Fortums nät

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Missuppfattningar inom genetiken: En litteraturstudie om hur missuppfattningar inom genetiken hos h?gstadie- och gymnasieelever kan motverkas

In schools, misconceptions about genetics can arise due to several factors, and the consequences of these misunderstandings can be significant. Lack of education can play a central role in the spread of misinformation about genetics. When teachers lack sufficient knowledge or do not have access to up-to-date resources, they risk inadvertently conveying inaccuracies to students. Additionally, students own preconceived notions and misinterpretations can be reinforced through interaction with their peers, creating a vicious cycle of misinformation. In this study, various misconceptions within genetics education have been identified and analyzed, while different strategies to prevent these misconceptions have been examined. The study revealed that the two most common misconceptions are the confusion between "genes" and "DNA" and the simplified perception of genetic determinism.

?Verksamhetsmålen, jag vet att de finns!? - en studie av en glesbygdskommuns verksamhetsmål utifrån personalens perceptioner inom Socialpsykiatrin

Blood-borne infectious diseases such as Human Immunodeficiency Virus (HIV)and Hepatitis C Virus (HCV) spread when the addicts share needles and injecting equipmentwithin contact networks. A quantitative cross-sectional study was conducted in Winnipeg,Canada in December 2003 - September 2004. Through a special questionnaire, respondentswere asked to answer questions about themselves and about their contacts, about relationshipsand how they shared syringes and other injection supplies. Blood tests were used to identifywhether they carried any blood-borne infectious diseases. We selected some variables from theoriginal data set.

Mätegenskaper för fruktsamhet och modersegenskaper i fåraveln :

The aim of this literature review was to suggest suitable index traits to use in the Swedish Sheep Recording Scheme for fertility and maternal traits. Since fertility and some of the maternal traits are not normally distributed advanced methodology is needed to calculate genetic parameters. Breeding is a tool to improve the economy of the farm and for the selection of breeders estimated breeding values (EBV) for important traits are of high value. In sheep breeding both lambs born and lambs weaned should be taken into consideration as well as the ewe?s maternal ability, which includes lambing ease, lamb survival, ewe behaviour as mother and the early growth of the lambs.

Hur patienter med hiv upplever bemötandet från vårdpersonal

Background: During the 1980s, the fear of HIV spread over the world. Health professionals'attitudes to patients with HIV, was negatively impacted because of their fear to be infected.Patients with HIV have therefore,during disease history's first two decades, experienced stigma and discrimination in the response from health professionals. Because of the increasing knowledge of HIV it is of interest to study patients' contemporary experiences of the encounter with health professionals. Aim:To explore how patients with HIV experiencing the meeting with health professionals. Method:Literature study with seven qualitative and three quantitative articles.

Projektdokumentation : Kritiska framgångsfaktorer

Projects of all kinds generate documentation that needs to be organized and stored for future use. Well adapted tools, together with a unified modus operandi need to be available for both the project members and those having a more organizing role if an organization is to be effective.A study of the tools available to project members at Svenska Kraftnät have been performed along with an analysis of the guidelines for the tools' usage. The study has focused on the needs of the project members, not the organization as a whole, thus providing a bottom-up approach to the problem instead of the more organizational top-down approach. Interviews of around 20 project members, whose roles include project leaders, technical experts and documentation supervisors, have been conducted to get an idea of the practical problems that exists.All systems, except for a local network storage device, were found to at least meet Svenska Kraftnät's current demands. The usage guidelines, however, covers only the general process that a project should follow and lacks detailed information on a per system level in several areas.

Hållbarhetsredovisning : Med fokus på negativ information

To establish sustainability reports is an increasing trend for more and more companies. This has led to a spread of the international framework Global reporting initiative, GRI, guidelines to make a sustainability reports. This trend has got a lot of critics from various stakeholders who believe that companies in these reports communicate the information in a way of window dressing. Both negative and positive information has to be represented according to GRI: s principle of balance.  Window dressing is created by adding a greater emphasis on the positive information. The researchers review the context of the negative information to study the extent to which it is reported and whether there are patterns and variations in the reported information.
