The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Study: Degree project in teacher education, Advanced Level 15pUniversity of Skövde Title: Using a blog as a tool for pedagogical documentation in interaction between two preschool teachers and parents. Pages: 39 Authors: Beatrice Johansson and Ellinor Pettersson Tutor: Urban Carlén Date: HT 2013 Keywords: Pedagogical documentation, interaction, blog, communication. The purpose of this study is to examine preschool teachers? use of blogging as a tool for pedagogical documentation and the parents? participation in the blog. The study examines the interaction between the preschool and the children?s homes as well as if the use of a blog contributes to a greater insight for parents in the pedagogical activities.In the latest curriculum, there have been a point of monitoring, evaluation and development, which seems to be a goal in the curriculum that creates uncertainty among the profession, how to configure them. Therefore, we felt that pedagogical documentation would be interesting to investigate.

Oavsiktlig lindrig hypotermi förekommer hos upp till 60 % av de patienter som genomgår en operation. Hjärnans förmåga att reglera kroppstemperaturen under ett operativt ingrepp påverkas av läkemedel som ges under anestesi. De åtgärder som vidtas innan och under operationen för att minska temperatursänkning är ofta otillräckliga och behöver förbättras. Idag finns få rutiner för hur oavsiktlig lindrig hypotermi skall undvikas för att minska det lidande som kan uppstå då patienten oavsiktligt utsätts för avkylning perioperativt. Syftet med studien var att påvisa de risker och effekter som uppstår i samband med oavsiktlig lindrig hypotermi perioperativt, samt att belysa framkomna skyddande faktorer.

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

To distribute goods to customers in urban areas is necessary to support the economic and social development in the cities, but has consequences that affect both residents of cities as well as the environment. The environmental effects of these types of transport involves not only the emissions of various pollutants, but also an increased noise level inside the cities. Many companies and organizations are working hard to change the distribution pattern to streamline transport in the urban area, while environmental impact is reduced. This is in line with what is called the City Logistics. The purpose of this thesis is to create a method for describing and measuring a given transport solution in order to compare it with an altered transport solution to achieve a more sustainable development.

Public WiFi networks is one of the dominant technologies for users to get public internet access. The problem is that the networks are designed for accessability rather than security ? a problem users seldom are aware of. Users who carelessly access WiFi networks may reveal sensitive information which, among other things, can lead to an identity theft. Previous research suggests that users must be educated and informed about the risks they incur, but not how this should be done.

Background: Markets in Financial Instruments Directive, MiFID, was implemented in Swedish law in 2007 and aimed to increase competition of the securities market in order to achieve efficiency and lower transaction costs and to enhance investor protection. Another aim was to increase confidence in the market. After the implementation of MiFID some doubts had been highlighted regarding its intentional effects. This evoked the authors? interest to examine the directive?s effects and its impact on investors? trust.Aim: To examine how various participants in the Swedish securities market experienced changes since the implementation of MiFID in 2007, and its impact on the securities market and minor investors' trust.Method: The study applied a qualitative method with a deductive approach to describe, interpret and understand the problem area.

In order to drive innovation and growth in a nation is it important to have innovative companies. Many of those innovative companies are smaller companies, which are in need of capital injections for expansion of its operations or to be able to produce a commercial product. In many cases the banks will not lend because they believe there is too great a risk that they will not get their money back. It is in this situation venture capital becomes interesting. Venture capitalists? see the potential the product and/or entrepreneur possesses and are therefore more willing to take the risk in investing in these companies.

The study begins with a historical background over the fisheries development in North America and in the Baltic Sea area in Finland and Sweden. As we can see the fisheries development depends on the interaction between ecology, state of production, politic and also social factors. In Sweden the fishery politic has changed over the period of the study. In the 1970: s the main politic focus was on the fisheries progress, expansion and rationalization. The State in Sweden took a vast part in this development and gave economic support.

Bakgrund och problemdiskussion: Under årens gång har det inträffat flera företagsskandaler. Det har sett bra ut på ytan men insidan har visat motsatsen. Fasaden kollapsar till följd av bristande kontroll. Intern styrning och kontroll och COSO:s Internal Controll ? Integrated Framework blir allt mer aktuellt för att få ordning och reda.

The spruce bark beetle (Ips typographhus) is one of the 25 000 species of insects in Sweden, an insect of great economic importance because it can alone terminate forest of high value. During the past decade, insights of climate change received with increasing attention. If the future brings a milder climate in the north and therefore a longer growing season, one would think that it would only affect the forestry to the better? Yet in recent time, outbreaks after storm felling seems to occur more frequently. The Spruce bark beetle ruins millions of cubic meter of Norway spruce (Picea abies) in Sweden alone, with more frequent storm felling and a larger amount of wind thrown threes in the forests there will also be room for an advancing reproduction.

In Sweden there are about 4 million hectares of bare peat (mire). This land has great potential to be transformed into productive forest land, provided drainage is carried out and, in some cases, even fertilization with ashes. Drainage of mires is necessary because the high groundwater table prevents trees from growing due to reduced oxygen availability. Some of the key nutrients that trees need to grow appear in too small quantities in mires, especially potassium (K) and phosphorus (P). Ash from the combustion of biomass contains these elements and is therefore suitable as a fertilizer.
