The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.

Drawing on a broad theoretical framework that includes theories about globalisation and honourculture, this thesis aim is to demonstrate that globalisation and honourculture, constitute a conceptual network, i.e a structural relational matrix in which concepts are embedded. Being part of conceptual network, these concepts are related to each other ontologically. The idea of conceptual network, and the thesis as a whole, draw upon what has been called ?relational perspective?This study aims to show the impact of globalisation on honourculture. The study shows the importance of narrative in the construction of discursive boundaries.

As social interactions migrate to the ubiquitous Internet we are facing a change in theway we relate to each other, which presents interesting new opportunities foranonymity to create identities. An aspect of this radically evolving technology thatexhibits strong possibilities for altering or producing identities is the rapidly growingonline game genre MMOG (Massive Multiplayer Online Game) which isentertainment that millions of people all over the globe engage in daily. Thisrelatively new platform for socialising has become of cultural and social significance,which is why it calls for examination and research. Thus, the main research questionsasked in this thesis are as following: How does players of MMOGs utilise the nighcomplete anonymity to present or modify their identities online? In which ways areMMOGs used as a platform for socialising and development of social groupdynamics? After observing a large group of players in a popular MMOG, as well asconducting several interviews with key identities within the group, I discovered three fundamental parts of identity creation, and created a model for use and applicationin different social situations and constellations..

This master thesis has been performed at the department of Machine Design at KTH, The Royal Institute of Technology. The thesis has been a part of a global development project in collaboration with Luleå University of Technology, Lund Faculty of Engineering and Stanford University. Corporate liaison and sponsor has been Immerse Global Inc. The project was also performed on sponsorship from the Product Innovation Engineering Program, PIEp. The thesis is a representation of some of the contributions made by the authors.The lack of clean drinking water is one of the key issues facing the world today.

The thesis has been written as a part of the Bachelor degree in Industrial engineering and management at the School of Engineering in Jönköping. The work is focused on the part of Husqvarna AB?s supply chain that is associated with the lorry transports to Italy. Husqvarna AB has approximately ten Italian customers, whose delivery patterns have been studied from January 2007 to July 2008. Some of the customers have a low delivery frequency and small amounts of goods that they therefore have not been fully analyzed in this report.

AbstractWhy don't (some) regimes with formal democratic features undergo transition to democracy? Which are the internal dynamics of these regimes that can offer comprehension to this state of affairs? The main purpose of this thesis is to advance the above questions, and, on a lower level of abstraction, examine the case of Egypt. The Egyptian regime is characterized by, for instance, a multiparty-system, steps toward economic liberalization, and some level of persistent state opposition, and has been considered on the way to liberal democracy, but can still hardly be estimated as such.Thus, the thesis takes part in a theoretical framework on democratization, and further analyzes the case of Egypt on grounds of socioeconomic development, political culture, and class configuration. By this contextual approach, the thesis adduces that a low level of modernization, an incomplete democratic political culture, and a bourgeoisie supported by the state are impending significant factors. The thesis additionally remarks on the interconnection of the adopted theories, and discusses a potential need for new theoretical propositionsA secondary aim of the thesis also gives some insights into the concurrence of regime stability and the absence of democracy in, what often could be labelled, authoritarian regimes.

The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.

This thesis is based on thirteen qualitative interviews with civil servants and politicians. The purpose of the study is to research these informants? attitudes towards integration and their reflections about immigrants? lower chances in an ethnically segregated housing and labour market. The theoretical frame of references is based on social constructionism and focuses on including and excluding power structures. The empirical material provides both structural and cultural explanations to immigrants? problems as regards inclusion in Swedish society.

It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.

AbstractIn this thesis I will discuss the relationship between the European Union and the regions of Europe. The development of the European Union has meant that many decisions are taken in Bruxelles. Many actors participate in the policyprocess ranging from national goverment to policynetworks of different kinds. An emerging actor has been the regions of Europe. Their influence on the policyprocess have grown and today almost all of them are represented in Bruxelles through Region Offices.

The elderly care is an area of great importance to women. Women are more often in need of elderly care; they work with the service and provide a majority of the informal service. Research shows that managers? work-related prerequisites are significantly different between the male dominated technical administration and the female dominated care and educational administration. Studies also show that what the highest managerial organisation gives priority to, often permeate the whole organisation.
