The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

 AbstractBackground: Among elderly people with dementia pain is a common problem. In older persons, particularly those suffering from dementia and cognitive impairment pain is often underdiagnosed and undertreated causing unnecessary pain, suffering and affect quality of life negatively. Dementia complicates the identification of pain when the natural ability to communicate decreases when a person is suffering from dementia. It is important that health professionals working with older persons with dementia are aware of the person?s pain expression.Aim: To clarify how older persons with dementia communicate pain expression.Method: To study this area a literature review was used.

Swedish goats are mainly held for cheese production and therefore, both milk quality and composition are of great importance for dairymen. Today, only few data exists on milk composition from Swedish dairy goats and the casein content is still unknown. One way to reduce the work load for goat farmers and increase animal welfare can be to keep goats and kids together for longer periods. The aims of this study were to investigate how milk yield and composition were affected when kids suckled their dams during 8 weeks, and to measure the casein content on farm level by a mid-infrared spectroscopy method, previously calibrated for goat milk. Lactating goats were kept in two different MIX- systems where the dams are both suckled and milked.

The main purpose of this study has been to survey the pupils? general comprehension of the content and aim of Swedish as a subject in upper secondary school and their attitude towards the subject. Furthermore the study aims at discerning whether there is a distinguishable difference between programmes with vocational and academic character.The study is based on the results of 101 answers from students in an opinion poll handed out at a Western Swedish upper secondary school. Throughout the analysis the results of the two programme groups have been weighed against each other. The result of the survey shows that:? The understanding of the aim and content of Swedish at upper secondary school is acceptable as a whole.

Introduction: Sleep is necessary for human survival. Difficulty sleeping occurs in about one in four adult person in Sweden, insomnia in every ten. There are several reasons for difficulty sleeping, where stress is one of the most common. The quality of life and health are affected negatively. Treatment with proven efficacy against insomnia is not only sleep medication, but also cognitive behavioral therapy, CBT.

Glycogen is the storage form of glucose and is used by the skeletal musculature as energy both for intense and endurance events. The glycogen content in the horse?s middle gluteal muscle is more than 600 mmol/kg dry weight, and almost 400 mmol/kg dry weight in the human?s Vastus lateralis. In some special occasions, for example in competitions with several moments on following days, there is a need of a fast muscle glycogen resynthesis. The feed intake is of importance for the velocity of the resynthesis.

Dementia is a concept that describes different conditions when memory and cognitive abilities degenerate. Approximately 140 000 persons in Sweden suffers from some kind of dementia. Many are stricken with behavioral and psychological symptoms of dementia, BPSD. The aim of this study was to illuminate nursing staff?s experiences of caring for persons suffering from dementia and BPSD within municipal and institutional care.

Detta examensarbete genomfördes våren 2013 på Karlstads universitet där TD Rail & Industry i Västerås stod som uppdragsgivare. Projektet innefattade att kartlägga nuvarande omlastningslösningar av enhetslaster mellan järnvägstransporter och vägtransporter, och utarbeta en konceptuell omlastningslösning med fokus på att öka järnvägstransporternas flexibilitet gentemot vägtransporterna. Där vikten lades på att utarbeta ett välarbetat helhetskoncept.Projektet genomfördes med designprocessen som grund och innehöll bland annat momenten; förstudie, kravspecificering, idégenerering, konceptval m.m.Resultatet blev en vidareutveckling av det redan befintliga systemet CCT som bygger på horisontell överföringsteknik och möjliggör därför omlastning av enhetslaster direkt under kontaktledning. Skillnaden mellan RES och CCT är att man tagit bort ombyggnationen av tågvagn och lastbilschassi, som var en av CCTs stora svagheter, genom två hydrauliska ?teknikplattor?.

The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.

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.

Purpose: Our purpose is to achieve a higher understanding of which factors University of Uppsala is using to attract and keep their existing workers.Theory: We have worked with Barrow & Mosley's the employer brand mix, this modelexplains 12 important factors that exists within the employer branding process. External reputation, internal communication, the board, values and corporate social responsibility, internalmeasuring systems, service support, work environment, rewards and acknowledgements, learningand development, performance estimation, team management and recruitment and introduction.Method: To achieve an understanding of our subject we have chosen to work with a qualitativemethod. This type of method is more considerate of the interviewed person?s way of seeingthings and also accounts for how the person answers. To answer our problem statement we haveconducted a case study on University of Uppsala where we used semi structured interviewsbecause we wanted to limit the risk of leading questions.Empirical findings: University of Uppsala were used as material for our empirical discussionContext: The main reasons that workers is attracted to and are staying at the university dependson the external status they achieve when working there, this combined with that the workers getsto be a part of the university's brand.

Det ställs idag större krav på studie- och yrkesvägledarna och deras kunskaper då det sker stora förändringar i vår omvärld, arbetsmarknad och utbildningsväsende. Vi vill med denna studie klargöra vilka kunskaper inhämtade från studie- och yrkesvägledarprogrammet, yrkesverksamma studie- och yrkesvägledare använder sig av i sitt yrke inom grund- och gymnasieskola. Vårt syfte är också att undersöka vad som möjliggör och begränsar användandet av dessa kunskaper. Vi kopplar följande frågor till vårt syfte; Vilka kunskaper från studie- och yrkesvägledarprogrammet använder vägledare sig framförallt av i yrkeslivet på grundskola och gymnasieskola? Vilka faktorer begränsar och möjliggör användandet av kunskaper som studie- och yrkesvägledare besitter? Anser sig studie- och yrkesvägledare sakna någon kunskap, som borde ingått i deras utbildning, i så fall vilken? De begrepp och teorier vi använt är Bourdieus Habitusteori, Social Cognitive Career Theory samt begreppen organisationskultur och yrkesroll.

Magisteruppsatsen studerar pedagogers erfarenhet av motstånd mot genusarbete samt försöker förklara motståndet utifrån socialpsykologiska teorier. Semistrukturerade intervjuer genomfördes med lärare som arbetar med skolans äldre åldrar. Samtliga lärare var engagerade i genusarbete på sina skolor. Tidsbrist samt ointresse var två former av motstånd som kollegor och skolledning utövade. En svårare form av motstånd visade sig vara tillmötesgående motstånd ? då motståndsaktörer ger sken av att vilja arbeta med genusperspektiv men i själva verket låter det bero.
