Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

To be able to plan for the expansion of a town, one needs a vision of the future appear-ance of the town. It is the current issues (social situation, supply and demand, political control etc.) which decide what the ideal for town planning is. This is turn is the steering factor of the physical structure of the town. Therefore, the town's structure is decided by these ideals.In this report, I will present planning ideals that have historically been, and which criticisms that have been directed towards them. With reference to these issues, I will present those guidelines and ideals we have today for planning of our towns.

In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.

This work is about the expanded conception of text and takes off in the use of this expression in the high school curriculum. The work begins with a theory chapter, where a few different definitions of text are the basis for reasoning about factors which can have contributed to an expansion of the conception. Hereby other important expressions, related to the expanded conception of text, as hypertext, multimedia and intermediality, are brought up. Further, is examined empirically how the expanded conception of text is interpreted, rhetorically and practically, by a few teachers in the High School. Finally, covered scientist?s theories are discussed and compared with the concluded empiric data.The study shows however, that the expanded conception of text in the curriculum has not become a conception for the teachers who were interviewed.

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Truancy is a problem in the Swedish schools today, just as well as in other European and other developed countries where educataion is gratuitous. Teachers all over Sweden go to classes with a clear and well-planned schedule for the day. But some are unable to do their work because of asent students. In this study I have chosen to focus on the perspective of the youths and the main question is: how do students discuss and think about truancy. During the study I have chosen a qualitative approach and have therefore done observation in various classes in a Swedish senior high school in a suburb outside Stockholm during twelve weeks.

BackgroundMalnutrition in hospitalized patients has a high prevalence. This led to an action plan against malnutrition that was conducted in 2012 at Enköpings hospital. This paper investigated the nursing staff perceptions of this project on nutrition and nutrient intake in two different departments, and whether these perceptions differ between departments. MethodAn inductive approach with semi-structured interview was used in interviews with eight persons from the staff of the two departments of the hospital in Enköping involved in the project. Interviews were recorded, transcribed and analyzed by content analysis. ResultsIn the interview material four categories were identified as well as six different subcategories. The different categories were: "Attitude", "Knowledge", "Procedures" and "Workload".

The aim of this paper is to examine venture capital in football player contracts in Sweden. This is a phenomena that have existed in Sweden since 1999 when the company Djurgården fotboll AB was founded, since then eight other companies have been started. These companies form an alliance with a football club and invest in player contracts. These contracts have high risk since it is valued by the performance of the contracted player. The venture capital firms have no formal control over their investments and they are showing negative results.

The aims of the thesis are to describe ways to obtain information needed for teaching andlearning practical and artistic subjects at a folk high school, to look into which part the library plays in this search for information, and finally, to see what the library can do to meet the information needs existing arnong teachers and students of arts and craft.Qualitative interviews were made with four teachers, seven students and one librarian atone folk high school, providing data for the thesis. The results indicate five main ways to obtain information among the persons interviewed:through books, by their own work process, by sensuous experience, throughcommunication with other people, and by the master of the craft passing on his/herknowledge to the apprentice.In this thesis some suggestions are also given for helping the library to meet the information needs of people involved in arts and craft work..

Half of Sweden?s 140 000-150 000 sows are culled and replaced by 75 000 gilts annually. Culling of old sows is necessary and allows new breeding material to enter the herd. However, many of the culled sows are young, and have not yet become profitable at the time for culling. Therefore, it is an important question for the pig industry, how to raise gilts to sows with a high and sustainable production level.

The bachelor's thesis is to examine the explanatory factors affecting the choice of capital structure in real estate companies. The analysis is based on data collected from the main financial reporting from 2007; all listed real estate companies listed on Swedish, Norwegian, Danish and Finnish stock market. Based on previous research and theories, we have defined five independent variables that are linked to the debt ratio, which are: profitability, growth, firm size, cost of debt and operational risk. The statistical tests have resulted in that we can say with certainty that profitable firms tend to have a lower debt to equity ratio. We can also say with certainty that property companies with high interest costs have a high level of indebtedness..

Laboratory work is a big part of chemistry education in high school. During our student training placement we have noticed that the laboratory work is not fully utilized to develop students´ chemistry knowledge. This problem made us want to investigate how the laboratory work in chemistry could be set, to become more meaningful for students. We introduced two preparation methods, and examined the outcome of students learning experiences and their acquisition of chemistry knowledge. This was examined both through surveys and observation.

Gerbera jamesonii is a plant with a large amount of pollen and various flower colours and a favourite host plant for Frankliniella occidentalis. The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.
