Spelar tarmcellernas interna fettförbränning en roll i regleringen av födointag?
Since several lifestyle diseases are associated with obesity much research is carried out within the area. Researchers have found that oxidation of fatty acids within the body?s cells may give rise to peripheral signals which regulate food intake, but it is still unclear where such a mechanism takes place. Although much evidence suggests that it is the hepatocytes in the liver that send signals regulating food intake, some researchers have begun to question this theory. Instead they argue that the mechanism takes place within the enterocytes since they are well localised in the gut for such assignment.
?Vissa kan man lita på mer än andra? . En studie i gymnasieelevers källkritiska bedömningar
The main purpose of this master thesis is to examine how high school students think when they independently are evaluating information for a school assignment. We examine what types of sources they use, and what their reasons are. Besides that we also examine what sorts of criteria they use when evaluating if a source is usable, and if there are any other factors that can have an influence for their choice of material. We have done a qualitative study with 23 students, where the students wrote down their answers in a questionnaire containing wide open questions. We have created our own tool for analysing the material by extracting the most general things in our chapter of earlier research, concerning the three questions which our study is based on.
Medborgaren som kund och brukare : En idealtypsanalys utifrån den kommunala demokratin
? Does Karlstad municipality have adequate institutional conditions to make the best use ofthe citizens? proposals??The purpose with the thesis is to investigate if citizens? proposals lead to a broader politicalinfluence. To answer that, I have done a case study about how Karlstad municipal administers citizens? proposals. The research assignment is: Does Karlstad municipal have adequate institutional conditions to make the best use of the citizens? proposals? The perspective is a democracy perspective and the theory is institutional theory and policy process theory.A selection of citizens? proposals that have arrived to Karlstad municipal between 2008 and 2010 have been studied in detail to analyze how the proposals have been administered and if it matters how the proposals are phrased.
Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
Bring Your Own Device : Analys av trenden, dess möjligheter och problem
Syftet med denna studie är att få en grundläggande kunskap kring begreppet bring your own device. Eftersom ämnet är väldigt nytt och att det finns en viss okunnighet kring begreppet är det intressant att ta reda på varför BYOD är en uppgående trend, hur svenska verksamheter tänker inför tillåtandet, vilka krav som ställs och vilka problem som följer. För att komma fram till dessa slutsatser har intervjuer genomförts på tre olika verksamheter. Varav en verksamhet har tagit sig an BYOD och de andra två planerar inför tillåtandet av BYOD. Det har även genomförts intervjuer på både unga studenter, unga i arbetslivet samt en jurist för att få en tydligare bild av företeelsen.
Electronic Journals, Just in Case, Just in Time, Just for You ? användning av elektroniska tidskrifter vid Chalmers tekniska högskola
This user study was carried out at the library at Chalmers University of Technology in Gothenburg in the spring of 1999. Chalmers wanted to investigate how much their employees use electronic journals. To facilitate decision-making and be cost effective, the library needed to know about their customers' opinions. The main purpose was to investigate the usage of electronic journals, how the library's choice of these journals affects the frequency of use and what the attitudes towards them are. A questionnaire was sent out to 2 400 employees; 477 replies were received.
Vox pop, enkät och fem funderar. : En kvantitativ innehållsanalys av enkäter i tre svenska dagstidningar åren 1997 och 2007.
The purpose of this BA-thesis was to study how three daily Swedish newspapers use a specific type of exemplars, which are recognized by a number of attributes. A photograph of the person that is interviewed always illustrates this type of exemplars and at least two persons are asked the same question. The three newspapers that have been compared in this study each represent one of the major types of Swedish newspapers: morning press, tabloids and local press. By using a quantitative content analysis, one month was examined in all three newspapers in the year of 1997 and 2007. Two of the theories that have been central in the thesis are Colin Sparks model of tabloidization, which demonstrates the process of tabloidization and McQuail?s description of commercialization.

Their difference in assignment demands different leadership, and that explains the occasion.

Matematisk problemlösning med förskolebarn : Lösningsstrategier på matematiska problem innehållande division/delning
Vårt syfte med det här arbetet var att undersöka hur förskolebarn agerar när de ställs inför två matematiska problem innehållande division/delning. Vilka lösningsstrategier använder de för att lösa givna problem? Vi valde att genomföra en fallstudie på den förskola där vi alla tre arbetar, och metoden vi använde oss av var deltagande observation, samt videofilmning. I studien ingick nio stycken femåringar. När vi transkriberade videoinspelningen såg vi att barnen använde sig av de olika lösningsstrategierna som vi tog upp i den teoretiska bakgrunden, i olika utsträckning.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.
Heuristisk utvärdering vs Usability Problem Taxonomy : En utvärdering ur ett klassificeringsperspektiv
För att identifiera och klassificera problem relaterade till användbarhet i mjukvarubaserade produkter används metoder speciellt utformade för detta ändamål. En av dessa metoder är Heuristisk utvärdering, men kritik har framförts mot denna metod och dess förmåga att klassificera användbarhetsproblem. I detta arbete jämförs Heuristisk utvärdering med en annan metod, i ett försök att utreda om kritiken är korrekt. Denna metod är Usability Problem Taxonomy, en metod skapad för att klassificera samt analysera användbarhetsproblem. Syftet med denna jämförelse är att ta fasta på vilken av metoderna som är lämpligast att använda vid klassificering av användbarhetsproblem, något som bedöms genom att undersöka metoderna och deras förmåga att noggrant klassificera användbarhetsproblem.
Sambandet mellan personlighet och alkoholkonsumtion samt alkoholrelaterade problem
Syftet med studien var att undersöka sambandet mellan de fem personlighetsdimensionerna; neuroticism, extraversion, öppenhet, sympatiskhet och samvetsgrannhet, och om de kan predicera vuxnas alkoholkonsumtion och alkoholrelaterade problem i ett svenskt urval. En webbenkät skickades till ett urval av anställda inom socialförvaltningen i Stockholms Län. Resultaten tyder på ett negativt samband mellan öppenhet och frekvensen av högkonsumtion av alkohol samt alkoholrelaterade problem. De indikerar vidare ett positivt samband mellan extraversion och kvantiteten av alkoholkonsumtionen vid ett typiskt tillfälle man dricker alkohol samt frekvensen av högkonsumtion av alkohol..
