The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

The aim of this work was to investigate how it is to move in hierarchy from crew toofficer within the seafaring profession and how to be affected by this. How you areperceived by the crew when going from to represent a part of a system to represent adifferent part of the same system and if you are ready to assume the responsibilities of thenew role entails?This is relevant and interesting as we will soon is facing at this transition. The work isbased on a qualitative approach. The choice of this method gave the information neededfor a perfect result.Interviews were conducted through personal meetings with active officers which alsoprovided the opportunity to ask follow-up questions and the respondents were given theopportunity to share their experiences.

Reinforcement is of great importance to fulfill the dimensioned strength of a concrete construction. This requires that the work needs to be carried out with adequate results that neither endangers the workers or the safety of the construction. Progressive development of the planning phase, construction documents, and construction methods is in constant need since the technology constantly evolves.In order for contractors to be able to get acceptances from their quotations requires that they have to increase their working pace in order to be able to leave a quotation with a lower price than the competition.Due to the increasing pace the different parts involved in the construction process is subjected to time pressure. The design stage, construction documents, work preparation and the execution are all affected when everything has to be finished quickly. To avoid problems, it is required that all parts are able to deliver good quality solutions and results under the influences of time pressure, which is not always easy.

During the last years around 100 000 immigrants have arrived to Sweden, people with different reasons and different goals for settling down in Sweden. The reason for immigrating to Sweden that will be dealt with in this thesis is following immigration, i.e. when someone moves here because they have relatives living in the country.The reason why it is interesting to study following immigration is that it is an affecting factor for how many that will immigrate to Sweden the following years and may then be used to make a forecast, based on how many first time immigrants there are. To be able to investigate the following immigration analyses are made with time series, logistic regression and Poisson regression. An ARIMA-model has been used to estimate the number of following immigrants in the future.The other part of this thesis will inquire the matter how inclined immigrants are to become Swedish citizens, whether they even apply for citizenship and also how long time it takes from the time when they fulfil the conditions for Swedish citizenship until they apply.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

Making the work in the public sector more efficient is something that has been seen as necessary during the later years. One way to do this on municipal level has been to apply solutions former used mostly by private companies. The organisational parts have also been adjusted to existing conditions in this work of change. For example more and more municipalities have come to use the purchaser-supplier model since the beginning of the 1990's. Norrköping, Linköping and Motala have been chosen in this essay for a closer study of the effects of the changes of the 90's, from an efficiency point of view.

This thesis is closely related to the Dynamically Self-Configuring Automotive System(DySCAS) project. DySCAS is a middleware for electronics in an automotive system. Thethesis work has been performed in cooperation with ENEA. Parts of the demonstrationplatform Self configurable High Availability and Policy based platform for Embeddedsystem (SHAPE) developed for the DySCAS project by ENEA have been used in theimplementation phase of this master thesis.The goal of this thesis was to evaluate how the Meteor MW, an offspring of the DySCASmiddleware, should handle QoS and to design a Quality of Service Manager (QoSM) for theMeteor MW that fulfilled hard real-time requirements. The thesis also had the objectiveof analysing and identifying the requirements on such a QoSM from a QoS perspective.Specifically the requirements to guarantee real-time support for applications running onthe MW.

Aim: The aim of this study was to describe what nurses experienced in connection with waiting time related frustration among patients and relatives in the emergency department and also what strategies nurses use to manage waiting time related frustration.Background: The numbers of emergency department visits are increasing and lead to waiting times which can cause frustration among patients and relatives, a frustration that nurses encounter in their everyday work and need strategies to deal with.Methods: This is a descriptive qualitative study. Interviews are conducted with five nurses, transcribed and analyzed by qualitative content analysis.Findings: The nurses feel inadequate and powerless when they meet patients and relatives frustration. In order to deal with patients and relatives frustration, they use the strategy of participation, which implies to involve and meet patients and relatives needs for information and to be seen. In order to prevent themselves becoming frustrated they use adaptability, by creating an inner calm, not take it personally and to distance themselves from the frustration.Conclusion: The result highlights the importance of managing the activity to reduce waiting time related frustration, for example through reflection and working for reducing waiting times. Further research is also needed..

The aim of this study was to gain insight into how two enterprises work with competence development and thereby study how the relationship between competence development and workers, employees, look like. The focus was on the workers motives and motivation towards a participation in a competence development course, their attitude to education, and how the transfer of skills gained from the course, into the workplace looks like. Further on, the work situations influence on the workers competence development has been taken into account.In the study, six people were interviewed in the role of either manager, coach or course participant who are employed in two different enterprises in the south of Sweden.The results showed that the participants were motivated by a strive for personal development or that the participants viewed education implementation as a part of the professionalcareer, which has resulted in a positive attitude towards the competence development course. The managers? motive for decisions about education was to change the prevailing attitude among the staff for the better and thereby strengthen the company?s brand. The work situation has encouraged the desire to participate in developmental education as the feeling of control has encouraged the workers to further development.

The purpose of my study is to examine how children through interaction are recognized and understood by other children and teachers at the preschool for one hour in the afternoon. This study gives voice to what young children in preschool do after snack. The overall purpose of this study is to find out what young children's experiences will be in preschool through interaction. The purpose of my research is to gain knowledge about how the time and opportunity for interaction exists between children 1;7-2;5 years, and educators as well as other children, and how this interaction appears during afternoon activities in the preschool.My research questions are:1) What experiences do children get in terms of their development of identity for one hour in the afternoon? 2) How does the interaction that the youngest children are involved in during the afternoon appear?

To turn the dairy heifers out on pasture is the most natural way for the cattle to get feed. At the same time it is cheap and if it is right treated a feed of high nutritive value. The problem today is to get dairy heifers to grow enough when they are grazing at natural pasture for the entire summer. Therefore, the opinions differ whether pasture is a resource or a problem. The increasing interest of pasture production is due to the fact that you can receive grants for preserving valuable natural assets and cultural landscape elements in the pasture land. A high grazing pressure is necessary to preserve an open landscape and a great variety of species. In the same time the heifers have to supply their nutritive needs in order to grow and be large enough to show heat and be pregnant in right time to calve with a sufficient body size and at an economically right age. This paper includes a literature review on natural pasture, pasture production, and growth of dairy heifers together with own interviews with dairy farmers about their point of view to the pasture husbandry on the farms, how they plan for pasture, look after natural pasture, treatment areas and take care of the calves and heifers. The results indicate that the time it takes and the demanded work are the biggest factors to how and why the farmers do as they do..

All over the world, scientists agree that to succeed with a conservation project, it is important to have a good relationship with the local people. If they do not receive a good impression of the project, they will not be willing to collaborate and the project will probably fail. According to previous studies, there are different factors affecting attitudes to conservation, like the level of education of the participant. Many studies have shown that the higher education the people have, the more positive attitude they have to adjacent conservation areas. Economical factors are also important, it is often stated that having more money results in a better attitude.

This study deals with work environment from a legal perspective. The study includes legislative history, legislation today and one empirical study. The legislation that concerns work environment (health and safety) in Sweden today is found in the Swedish Work Environment Act (WEA), the Work Environment Ordinance (WEO), Provisions issued by the Work Environment Authority, related legislations and also collective agreements. The WEA, passed by the parliament in 1977, came into force on the 1st of July 1978 and it defines the framework for Provisions issued by the Work Environment Authority, which is an authority superintended by the Swedish government. These Provisions contain more detailed stipulations and obligations with reference to the working environment.
