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.

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

It is important to know what is normal in the wound healing process in order to determine what happens when a wound does not heal as expected. If the amount of bacteria in the wound gets too large the body will not be able to defend itself and it becomes an infection. Colonization and infection are common elements in wound management and it is often the veterinary nurse role to deal with wounds in a proper manner. Antibiotics are drugs that either kill or inhibit the multiplication of bacteria or fungi, and have been in veterinary medicine for approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it.

Schools inspections investigation has shown that most pedagogues are experiencing significant challenges to stimulate students and to invite students to participate and to influence the teaching structure and content. This study is based in the school inspections school questionnaire from 2013 which shows that Vallentuna high school results in two categories stimulation as well as participation and influence gets a low index value compared to all participating school units. Previous research has shown that the field studies creates greater amount of stimulation, increases students? participation and provide experience of a bigger influence. Careful preparations are also important and the right form of field studies.

The sandy beaches of Vänern are threatened by overgrowth and thereby the biodiversity is at high risk to decline. This study is based on an inventory of vegetation of overgrowth character and mosses. The frequency and spread of mosses is perceived as an indication of initial or present overgrowth. External factors that have been taken into consideration are wind-, wave- and ice erosion, the slope of the beach, wear and grade of exposure. The purpose of the investigation is to control the beaches grade of overgrowth and find out which external factor is of most importance for the maintenance of the biotope. The results show that the beaches environment is affected by the slope of the beach, grade of exposure, size, wear and overgrowth.

Abstrakt All around the world there are a lots of people that suffers from chronic pain. One great factor for the devolopment of chronic pain is the phenomen fear-avoidance/kinesophobia that appear to have negative effects on rehabilitation of chronic painproblems. The aim of the present study was to describe and identify how patient that took part in a rehabilitationprogram in year 2004 and 2005 with focus on behaviourchanges estimate their fear-avoidance/kinesophobia and examine if there was any changes estimate fear-avoidance/kinesophobia respectivly before and after and respecivly before and 12 month after the rehabilitationcourse. The study had a describing prospecitive design. Data was collected by the Swedish version of Tampascale for kinesophobia.

PURPOSE: To analyze how companies in the Swedish beer industry strategically workingwith CSR externally in order to increase their legitimacy.METHOD: Qualitative interviews and text analysis to enable data to stakeholder analysis.MATERIAL: Respondent interviews with key individuals, textual analysis of CSR-relateddocuments of the largest beer producers in Sweden.MAIN RESULTS: The study shows that it is possible to distinguish three main categories ofstakeholders to the beer producers. These have various high stakeholder values, wherecustomers are those with the highest value, then consumers and third critics. That these havevarious high values allows different strategic approach to the key issue of how preventivemeasures, that can be said to work against their own products, affects the beer producerslegitimacy among stakeholders..

AbstractTitle: Does supplementation with omega 3 improve oxygen uptake among athletes?Author: Jonna Gustafsson and Maria Bohlin Nygren Supervisor: Frode Slinde Examiner: Ingrid Larsson Programme: Programme in dietetics, 180/240 hp Type of paper: Bachelor?s thesis in clinical nutrition, 15 hp Date: May 26, 2015Background: Previous research has shown that omega 3 fatty acids may improve cardiovascular functions by decreased aggregation and increased red blood cell deformability. This produces an increased blood flow and could have a potential effect on oxygen uptake. Optimal aerobic capacity is a determinant factor of performance within endurance exercise.Objective: To compile scientific research of the possibility that omega 3 supplementation could improve oxygen uptake among athletes.Search strategy: The literature research is based on searches in PubMed and Scopus with the terms ?Physical Endurance?, ?Oxygen Consumption?, ?Fatty Acids Omega 3?, ?Dietary Supplements?, ?Exercise?, ?Fatty Acids Essential?, ?Docosahexaenoic Acids?, ?Eicosanoic Acids?, ?Fish Oils?, ?oxygen consumption?, ?maximal oxygen consumption?, ?VO2 max?, ?athlete?, ?omega-3 supplementation?, ?physical endurance?, ??-3?, ?omega-3?, ?Maximal Aerobic Power?, ?Oxygen Uptake?, ?VO2? and ?Maximal Aerobic Capacity?.Selection criteria: Randomized controlled trials (RCT) with an intervention of omega 3-supplementation during three weeks or more were included.

English title: Is a literary canon necessary? A comparative study based on seven senior high school teachers´ different approaches towards the place of canon in the education of Swedish. The purpose of this study is to describe and analyze how seven senior high school teachers relate to a literary canon in Swedish while teaching literature in senior high school, identifying similarities and differences among the teachers? view and opinions about an outspoken formal literary canon and a silent, informal canon.The earlier research opens the door slightly to the American debate and gives insight about the complexity of the concept of canon. The study continues with exploring possible relations to postcolonial theory and didactics.    The study reveals that the majority of the concerns against canon are that too much centrally governed education may decrease the motivation and commitment of the teacher. In addition, the dominant canon passivizes a certain variety of literature, thus various points of views. On the other hand, views on the equalizing effect of canon on the level of education and its benefits in increased knowledge of the history of the literature are salient. .

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

This is a study of some risk factors for Diabetes Mellitus (DM) in dogs. As a pilot study it is meant to give information to be used in a planned later, larger and better controlled study. The present study hypothesized that suboptimal feeding (high percentage of homemade and table foods), lack of activity and overweight contribute to the risk of DM. Twenty consecutive dogs diagnosed with DM at the Veterinary University Clinic in Uppsala between 2000 ? 2003 were chosen as the experimental group.
