Begreppet lågkolhydratkost myntades för första gången 1921 och efter det har en rad olika varianter av kosten uppmärksammats. En svensk variant som har fått stor genomslagskraft är Low Carb High Fat (LCHF). Där förespråkas, i motsats till de nuvarande svenska näringsrekommendationerna, en hög andel fett, gärna mättat, samt en låg andel kolhydrater. Viktminskning har visat sig fungera effektivt med LCHF och lågkolhydratkost. Det finns även undersökningar på att kosten har en positiv inverkan på blodfetter, blodtryck, diabetes typ 2, humör och mättnad, men dessa resultat är fortfarande tvetydiga.

This report discusses the development of lessons based on laborations for middle and high school.The purpose of the project was to research the possibility to affect students' attitude towards physicsthrough well-planned stimulating lessons. The lessons were based on the Light and Lasers OutreachKit, a teaching package made by the organisation Laser Classroom, and have been adapted for physicsin middle and high school. The lessons were developed on a pedagogical and didactical ground andwere improved with surveys and peer and self assessment. The lessons were based on laser light and itsproperties. One lesson covered the topic of single-slit diffraction, while the other treated geometricaloptics.

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.

Lerbodaälven is a river in the municipality of Kil which, due to high phosphorus content is not meeting the requirements for good ecological status according to the Water Framework Directive. The purpose of this report is to investigate the causes for the high content of phosphorus that has been measured in Lerbodaälven between 1995-2010. Four questions will be answered in this report. 1. Does the sewage treatment work affect the phosphorus level in Lerbodaälven? The result from the time series analysis shows that the sewage treatment works have a small impact on the phosphorus level in Lerbodaälven.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as ?embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area.

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 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.

Syftet med denna studie är att belysa gymnasielärares syn på begreppet hälsa och hur de definierar hälsobegreppet inom ämnet idrott och hälsa. Vidare är syftet att undersöka på vilket sätt dessa lärare beskriver att de arbetar med hälsa i ämnet på gymnasiet utifrån kursplanen Idrott och hälsa 1. Studien utgår ifrån följande frågeställningar: Hur definierar lärare i idrott och hälsa begreppet hälsa? Hur beskriver lärare i idrott och hälsa begreppet hälsa inom ramen för idrott och hälsa? och Hur framställer lärare i idrott och hälsa att de arbetar med hälsa i sin undervisning utifrån kursplanen Idrott och hälsa 1?Kvalitativa intervjuer med lärare i idrott och hälsa på olika gymnasieskolor har använts som metod för att insamla data till undersökningen. Studien är en kandidatuppsats och är inte generaliserande för en större population.

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..

Introduktion: Regionalt cancercenter (RCC) har i samarbete med Sveriges kommuner och landsting (SKL) beslutat att varje patient med en cancerdiagnos ska bli tilldelad en kontaktsjuksköterska.Syfte: Att undersöka hur väl implementeringen av kontaktsjuksköterskan har fungerat inom den onkologiska vården på Akademiska sjukhuset i Uppsala samt om de kontaktsjuksköterskor som finns arbetar i enlighet med SKL:s definition.Metod: Kvalitativ metod med semi-strukturerade intervjuer av åtta patienter med olika cancerdiagnos.Huvudresultat: Fem av de åtta deltagarna blev tilldelade en kontaktsjuksköterska eller motsvarande när de fick sin diagnos, antingen i direkt samband med diagnosen eller i ett senare skede. Resultaten tyder på att de patienter som ingår i någon slags forskningsstudie upplever sig ha en kontaktsjuksköterska som underlättar för dem och även deras behandling. Patienter som inte ingår i läkemedelsstudier upplever inte att kontaktsjuksköterskan har arbetat enligt SKL:s definition.Slutsats: Forskningssjuksköterskor är den personalkategori som arbetar närmast definitionen av kontaktsjuksköterska. Brister gällande sjukvårdens tillgänglighet, förmåga att ge fullgod information samt att erbjuda anhöriga stöd har uppmärksammats. Ytterligare forskning måste utföras för att resultaten ska kunna bekräftas.  .

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.
