The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

There exists a great need among companies and other organizations to be able to visualize statistics. It?s also increasingly common to ask for web-based solutions for increased flexibility and accessibility for users. This paper describes how large amounts of geovisual data, for a large number of regions, can be visualized in an interactive and well-presented manner. The paper let?s you walk through two application scenarios, developed in a Flash environment, using the GeoViz component library for visualization. The first application has been developed for Statistics Sweden (SCB), to give a solution on how to visualize statistics for Sweden?s zip code regions.

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

The purpose of this study is to find out what preschool teachers think about antisocial children's literature. Based on five qualitative interviews with teachers at a preschool that works with a standard critical approach. In order to fulfill my purpose with this study, I focused on how these teachers felt that it was important to use the standard critical children's literature in preschool. I wanted to find out what the teachers' thoughts were on the concept of standard critical children's literature and how and whether they use it in their daily activities. When I analyzed the results of my interviews I used the queer theories that include standard critical pedagogy and literature in preschool.

Being able to predict the future had been an invaluable competitive advantage for any corporation. Forecasting is a vital part of any business, hence a good forecast allows enterprises to invest in a beneficial way. However, there are several ways to prepare forecasts and the forecast methodology can vary. An industry that is dependent on forecasts is the energy industry. By predicting consumers' energy consumption, Swedish energy companies can hedge on the Nordic power market Nord Pool.

The telenursing service deals with offering the public guidance as what to do with their health and illness concern. More specifically this service includes triage, support, advice, education, referral, information and coordination. To conduct telephone advice is a complicated task to perform and put specific demands of the nurse?s communication skills.The purpose of this study was to critically review the impact of telephone counseling focused on context of implementation, perspective, design and clinical relevance by a sample of studies within the field.The critical review focused on inconsistencies in the material. Strengths and weaknesses of the studies were explored, with emphasis on detecting areas of skill gaps.Twelve of thirteen studies were made in the context of telenursing.

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

The purpose with our essay was to examine which clients/patients get treatment for alcohol problems from either health care units or social service units. We also wanted to find out how staff in these units considers the importance of social background in the assessment of treatment. The questions we have focused are: How do the clients/patients get in contact with the units? How does staff in these units consider the importance of social background in the assessment of treatment? How is the social background like for the present clients/patients? To fulfil the purpose with our investigation and to get answers to our questions, we performed an explorative examination and applied a qualitative method in the form of a semi-structured interview with six persons. The investigation showed that clients/patients get in contact with the units by looking for treatment by themselves or by relatives and other organisations.

Today there are various methods to use when euthanizing horses. Earlier the use of free or captive bullet was the most common method, but in recent decades this has changed and chemical euthanasia is now considered the most common method. The chemical euthanasia has in Sweden been dominated by the use of barbiturates. Somulose® entered the market in the beginning of the 90?s as an alternative to previous chemical euthanasia.

The purpose of this essay is to review the Swedish international development cooperation carried out by Sida to control whether the implementation of the international aid is compatible with the policy. There are a lot of different ways to implement the economic aid that are being used by the donors today.

To answer the main question there are two themes in the essay:? What kind of countries is supposed to receive developing aid from Sweden according to the policy?? What kind of countries is receiving the aid, and how can this be understood?This essay is mainly based on quantitative data obtained from Sida, together with index of corruption and poverty will the different types of Swedish cooperation countries be described.The conclusions of this essay are that there are two objectives of the policy: to fight poverty, and to strengthen the civil rights.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.

This study covers reading comprehension and the introduction of the "Tell me" approach as proposed by Chambers (1993) to a group of teachers in a Swedish F-3 school. Five teachers got to use the method for three weeks and were interviewed before and after the experiment to analyze their current ways of working and reactions to using the method in everyday tutoring. The result from the first interview showed that all of the participants had been using methods to improve the children?s reading comprehension prior to the study, but no one had tried the "Tell me" approach. After trying the method throughout the test period, all of the participants were positive about the methodology and showed an interest in continuing the use of it.

Proteins are vital to all cells in the body. They consist of long chains of amino acids. To be able to study the amino acid composition of a protein it is necessary to hydrolyse it, followed by separation and quantification. When the protein is hydrolysed, in this case ß-lactoglobulin, the protein is divided into individual amino acids. The method that traditionally has been used to hydrolyse proteins takes 24-72 hours to complete.
