Nowadays naval units are participating in international missions, where new and in many cases tougher conditions will affect their propulsion. This essay deals with some of the now developed nanostructure coatings and gives a presentation of how the coatings could function on some exposed parts of the naval powertrain. The essay investigates the possibility that the coatings can be used as a protective layer that will reduce or prevent wear on selected parts of the naval powertrains. As a basis for the essay, nanotechnology is described, as well as different reasons that wear occurs and application techniques for coatings The conclusion is that nanostructured coatings can be applied and provide a much better result on hardness and wear resistance as of naval powertrains compared to micro-structural coatings, both for manufacturing and renovation. The essay presents a few examples of the military utility of the nanostructure coatings as well as suggestions for further research..

Bachelor essay in political science by Andreas Byfeldt, autumn 2007?The practice of deliberative democracy- limitations or enhancements of representative democracy??Supervisor: Erik AmnåThe purpose of this study is to find out what impact the practice of deliberative democracy might have on a representative democracy. What effects deliberative democracy could have in this context are scientifically as well as publically relevant seeing that participation in representative democracies as well as the forms of representation is altering.The essay contains both a theoretical segment and a case study. The information regarding the case is based on the results from a questioner, conversations by and observations from the author. In addition an analysis is performed in the case study.The conclusion of the essay is that there is too little empirical research on the subject of deliberative democracy to make a qualified conclusion about what effects the practice of deliberative democracy could have on a representative democracy.

2007, Swedish television, ?Uppdrag granskning,? aired their story about ?Louise? from Vetlanda. A drug dependent father had gotten custody of his daughter and sexually abused her from the age of 10 to 15. The local social services got several notifications about Louise suffering of negligence, and did investigate the family several times without taking any actions to protect her. At one time, father and daughter were living in his trailer placed in a gravel pit, and the police worried about her and called social services, because it was below cero degrees outside.

Furthermore, -the study analyzes what music itself, and its performance mean in these students? social and personal lives.

Barnamordsplakatet (a Infanticide Proclamation) of 1778 was a circular allowing unmarried mothers to give birth at an undisclosed location without giving up the name of the father. The proclamation was supposed to ease the situation for the unwed mother in Sweden.The aim was to investigate whether women in Assembly of Hällefors, far from government and close to remote forest Finnskogen, was affected by the Infanticide Proclamation, between 1771 and 1830.Case studies has been done on people who had illegitimate children, if they were convicted, what the crime was and what the punishment was. The investigation is made at a local level and compared against national analyzes on the same theme.A lot of illegitimate children were born in Grythyttan nearby and slightly less in Hällefors, compared to other places of Sweden. Mothers and fathers were convicted in the district court for crimes, including, sexual intercourse between unmarried persons. More women than men were convicted.

The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.

The purpose of this study is to examine a preschool's work to counteract traditional gender roles, which strategies are used and how norms about gender roles are produced and treated. The study also examines whether the preschool has an intersectional perspective in it's gender work, which analyzes how they relate to other categories such as ethnicity, race, class, age and sexuality in their work. I have been observing and conducting four interviews with teachers at a preschool with a gender profile. In my analysis I have used Foucault's theories about discourse and power. The results show that the informants had a high awareness of gender and that the main strategies used were: an individual perspective, seeing the individual and not the sex, and a gender-neutral strategy, removing everything that is gendered, for example, in language and environment.

This thesis aims to analyse a time series containing the annual accumulation rate of minerogenic matter in the lake Kassjo?n. First there is a theoretical survey of some frequently used tools for the analysis of time series in the time domain and in the frequency domain. This survey is followed by a simulation study that illustrates how the theoretical tools work in practice. After this, the time series "toolbox" is used to analyse the time series from Kassjo?n (5701 data points).

Could patterns change the way we as consumers feel about a product as it ages and wears down? Why do some products increase their value as they are being worn downand others do not? Could the same affection that increases with your favourite jeans or an old, worn down, scratched and beautiful wooden furniture, be applied on otherproducts with different ability?s and history?The goal was to explore patterns and beautiful aging in products to increase the consumers desire to keep the well used product a little bit longer. Not to prolong the products ?lifetime? from brand new till it?s no longer inhabit their main function, but at that precise momentwhen you as a consumer decides to through it away in favour for a new, updated version. To buy ?new and fresh?.Patterns with different expressions, colouring and size, were explored that increase the value of a product which in this project contained handles and varies of surfaces on casseroles, frying pans, whisks, cutlery etc.

Inventory management is a key part of a company?s logistics function and is of great importance to companies as it is a substantial cost. It is of high importance for a company to make sure that the warehouse is efficient as possible. In this thesis two factors that hurt a warehouse?s efficiency are introduced; inventory inaccuracies and lead-time variations.This thesis has been dedicated to analyze how inventory inaccuracies and lead-time variations arise and how to eliminate them.To be able to solve this question we have used a qualitative research method.

Environment friendly transports are one of the main topics in the industry and society today.Shell organizes an annual university competition called Shell Eco Marathon. The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.

This report deals with the design of a controller for SmartMedia? flash memory cards, based on a hardware description found in the SmartMedia? Interface Library - SMIL. The design was made on logic gate level, using standard cells in OrCAD Capture. After simulation of the design in PSpice A/D, it was exported as an EDIF netlist, which was used to make a chip layout in L-Edit, a layout tool for making integrated circuits. The layout was made using a method called Standard Place and Route - SPR, where the layout tool places standard cells from a library and connects them according to the EDIF netlist.

Legionella can be prevented, the question is how. This report is a degree in construction engineering education at Chalmers University in Gothenburg. A comprehensive written publication for Legionella-safe plumbing installations is not available and therefore requested. The purpose of this report is to present preventative measures against Legionella bacteria growth in tap water and in other systems where Legionella bacteria are a potential problem. Technical solutions are presented including how different systems function and what their advantages and disadvantages are.

The purpose of this thesis is to determine whether the student councils at two schools really have the power to influence, or if it is a matter of mock democracy. I wanted to determine how the student councils work in reality. I conducted my investigation through personal and qualitative interviews with the board of the student council, a social studies teacher and the principle/school management at both schools. After the interviews I compared an analysed my findings. The results show that the two schools work very differently when it comes to studentdemocracy, and even have very different levels of ambition when it comes to the degree of influence that the student council should have at their respective schools.

The present study aims to examine how teachers write polemical articles. This genre often occurs in national standardized tests in Swedish schools. The study seeks to analyze argumentative structures in the articles. It also categorizes assessment notes written by the teachers in response to each others? articles, by interpreting response texts.    The examination shows that there is uncertainty among the teachers about how to create structures in argumentative text types.
