We derive the equation linking the Weyl tensor with its Lanczos potential, called the Weyl-Lanczos equation, in 1+3 covariant formalism for perfect fluid Bianchi type I spacetime and find an explicit expression for a Lanczos potential of the Weyl tensor in these spacetimes. To achieve this, we first need to derive the covariant decomposition of the Lanczos potential in this formalism. We also study an example by Novello and Velloso and derive their Lanczos potential in shear-free, irrotational perfect fluid spacetimes from a particular ansatz in 1+3 covariant formalism. The existence of the Lanczos potential is in some ways analogous to the vector potential in electromagnetic theory. Therefore, we also derive the electromagnetic potential equation in 1+3 covariant formalism for a general spacetime.

This is the end report of my final exam at Medieteknik. It covers the planning, work process and review of a Flash based web application that I set out to do. The goal was to create a user friendly, interactive e-shop with embedded functionality for playing music, displaying rich media content and researching possible payment solutions, to enable buying music files online. The project involved creating the user interface, the programmatic functionality of a Flash client (an SWF file). Also, setting up an Apache HTTP Server and establishing a working ?bridge? between the Flash client and the web server with Flash Remoting components and AMFPHP.

The existence for companies today consists of constant challenges with customers that want more individual products with high quality as quickly as possible. For a company to be able to have a short delivery time, it must also have a short production time. This makes streamlining and improvement of processes a big part of a company?s workThis thesis has been carried out together with the company Lasermax Roll Systems AB, a world-leading manufacturer of feeding, finishing and monitoring systems for high-speed digital printers. They manufacture their products according to the assembling for costumer order principle.The purpose with this thesis is to map and analyze, the assembling process and the test process at Lasermax Roll Systems AB.

This paper aims to present a theoretical understanding of the emergence of extreme right- wing populist parties (ERP), and more specifically the electoral breakthrough of the ERP party, Sverigedemokraterna in the municipality of Karlskrona. By doing so the study is constructed as a theoretical framework, where the empirical material and the theoretical aspects are interwoven. This means that the theoretical framework also functions as an analytical part. The paper shows how Sverigedemokraterna could be understood as an ERP party, based on e.g its populist anti-establishment critique, and its critique towards the ?immigrant issue?.

The purpose of this master thesis is to examine some pre-school teacher's and parent's perceptions about communication within the pre-school context and how this can be described in terms of conceptual dichotomy.The empirical investigation consists of a qualitative study, where data have been collected by interviewing two focus groups and one single parent.The main theoretical tools which the study uses as its premiss is Derridas' theory of hospitality and Habermas' theory of deliberative dialogues. The study also considers the conception of the intermediate domain as an arena for communication between parents and pre-school teachers, and further more the conception of stereotyping in social and cultural contexts.In order to explore these processes I have used the qualitative method of interpretation; Hermeneutic, also with a narrative approach to the analysis.The results and the analysis of the data show that the interviewed parent and pre-school teachers have a poor sense of knowing how much influence to give to each other. The parents were not satisfied with the level of open communication and how the pre-school teachers share information of the activities..

This thesis examines the subject of reference interviews and the ways librarians form an opinion of users information needs. Using literature and interviews with three librarians I look at the questions below: - Why and when are reference interviews needed? - What significance do they have? - What ideas exist about the performance of reference interviews? - Are there any differences in librarians views of the questions above compared to views in the literature? Results from literature studies and interviews show that reference interviews can be important when librarians try to find out more about users information needs. However its neither necessary nor possible to analyse all reference questions. Librarians therefore need to determine if a reference interview is needed or not.

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.

The aims of the study were to investigate the prevalence and antibiotic resistance of Campylobacter jejuni and Campylobacter coli in chicken and chicken products, and to investigate farmer awareness of antibiotic resistance development. The study was conducted in the Can Tho province in Vietnam during six weeks in October to November 2008. Ninety-six samples from raw chickens were collected from twelve market places and analysed for the presence of Campylobacter. A total of 96 cloacal swabs from 20 farms were obtained and analysed for the presence of Campylobacter. Farmers were asked to answer eight questions concerning the housing of the chickens, modes of handling sick animals as well as use and knowledge of antibiotics and resistance development to antibiotics.

This quantitative study explores how employee perceived efficiency within customer service is affected by standardized routines, digital tools, and motivational factors. The study is based on survey data collected from 42 employees across five customer service departments in a larger organization. The theoretical foundation integrates Weber?s bureaucracy theory, the Technology Acceptance Model (TAM), and the Job Characteristics Model (JCM), allowing for a multidimensional analysis to capture the employees' experiences of efficiency. Findings reveal a statistically significant positive relationship between perceived efficiency and both standardized routines and perceived digital tool usefulness and ease of use. Furthermore, the study identifies that skill variety and task significance are positively correlated with experienced meaningfulness, which indicates a potential mediating relationship between these motivational aspects and perceived efficiency.

This paper sets out to investigate how companies can create advertisement that focus not only on selling but also on entertainment. The research is based on seven TV-commercials produced by the Swedish food chain ICA. The commercials were analyzed according to the methods of discourse analysis, semiotic analysis and rhetorical analysis. Furthermore, the research compares the analysis made with the thoughts and ideas of Tobias Karlsson, Head of marketing and communications development at ICA to find out how the comprehension of the commercials correlate with the original intentions made by the company.The study shows that ICA creates a commercial that contains the perfect mix of rhetorical approaches, communication strategies and entertainment mixed with gravity. The study also shows that ICA fails with its primary goal which is to sell selected products; however, by producing the entertaining commercials, they manage to strengthen their brand.

ästerbottens färgrika stenskatter - Spatiala presentationer och analyser av skifferfynd i Västerbottens län(The colorful stone treasures of Västerbotten ? Spatial presentations and analysis of slate artefacts in Västerbotten County)This essay pertains to the spatial distributions and analysis of slate artefacts in Västerbotten County, Sweden. The authors aim is to give answers the issues of what the distribution patterns of slate artefacts can tell us about the prehistoric humans in this area. By using GIS software and geospatial analysis the author strengthens the theories about separate interior and coastal economies, as well as the theory that the main share of production of slate artifacts are linked in the interior of the County, the author also refers to earlier research, both domestic and international. The theories of non-pragmatic preferences by the late Mesolithic and Neolithic people for red colored slate are also added to.

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

In this multistudy the aim was to measure the effect of mindfulness and yoga in negative stress. Is it possible for yoga and mindfulness to increase awareness and acceptance to inner and outher circumstances? Mindfulness-Based Stress Reduction (MBSR) has shown good results in how to cope with negative stress and how to stay calm in a stressful envirorment. The qualitative study where Visby Yoga Center and Stockholm Yoga Shakti attended in a survey. Correlation showed no relationship between stress and mindfulness and no significant value, n=20, Cohens d=0,16.

Background: Phonemically balanced word lists are used when obtaining speech recognition scores in noise. These lists are designed for adults, but are still used for children. To properly obtain speech recognition scores in noise for children, normative data is needed to show what differences there are to be expected between children of different ages. Purpose: The main purpose is to obtain normative data for children in the ages of 7, 10 and 13 years for speech recognition scores in noise using words and to compare these with each other and with normative data of adults. A further purpose is to examine if there is any practice- or exhaustion effect to be seen when obtaining speech recognition scores in noise for children in the ages of 7, 10 and 13 years.Material: The participants were ten 7-year-olds, ten 10-year-olds and ten 13-year-olds.

Library and information science (LIS), being a research area characterized by theoretical discord and definition disarray, provides an interesting field of inquiry. Its content, boundaries, scope and superior identity are not clearly stated. This Master s thesis focuses on a thus far unexplored perspective on the discipline: a conceivable statistic and causes- and- effect relationship between the LIS students appreciated identification with the superior identity of the discipline, and the chosen vocational direction within the field. This relationship is examined through testing a working hypothesis on the results of a major quantitative questionnaire survey. The theory behind our research derives mainly from Thomas Kuhn and Richard Whitley.
