Det sjuka benet och de friska människorna : en studie av osteoporos och osteoartrit i kvarteret Banken 1 i Visby

This essay deals with the diseases osteoporosis and osteoarthritis in a medieval population from Visby in Sweden. The aim has been to evaluate to what extent and in what way these diseases have influenced the people of a relatively large harbour town during the Middle Ages. 24 individuals were analysed osteologicaly and 19 of them became subject for measurements of bone density through DEXA readings. Furthermore four individuals were x-rayed based on external differences due to osteoarthritis and a change in the depression at the base of the medial surface of the greater trochanter. Similar studies have been made in Trondheim, Norway and Wharram Percy, Great Britain.

Promotionsarbete med unga i förorten : - En kvalitativ fallstudie av RGRA, Rörelsen gatans röst & ansikte

This studie explores how a promotive youth movement that aims to activate adolescents in economically and socially exposed areas, can affect the youth?s participation in society and oppose their experience of stigmatization. The youth movement, whom is being studied, uses urban art expressions as a mean to engage and motivate the adolescents.

The result has been analyzed through Pierre Bourdieus field theory.

Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?

The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.

Tillgänglighet 2010 ? om implementeringen av tillgänglighet på biblioteken

Högfrekvenshandel ? Ett hot mot de finansiella marknaderna?

?Högfrekvenshandel har de senaste åren växt till att bli en betydande kraft på de finansiella marknaderna och således även fått mycket medial uppmärksamhet. Den här medieuppmärksamheten intensifierades den 6:e maj 2010 då "Flash-krashen" inträffade på Dow Jones indexet i New York och påverkade marknader över hela världen.Vår avsikt med den här kandidatuppsatsen är att kritiskt granska högfrekvenshandeln som fenomen samt den diskussion som förs angående ytterligare reglering av handeln. Detta görs genom en inledande period av litteraturstudier som kompletteras med djupintervjuer av olika aktörer på marknaden.Våra resultat visar att högfrekvenshandeln inte för med sig så stora negativa effekter som media målar upp, och att den forskning som gjorts på ämnet indikerar att handeln främst tillför positiva effekter i form av ökad likviditet och minskad volatilitet.Uppsatsen behandlar även dagens regleringssituation och analyserar de förslag på åtgärder som har lagts fram på EU-nivå. Vår analys visar att många av de förslag som diskuteras är direkt missriktade och inte adresserar det egentliga problemet? en situation som kantas av oklara roller gällande tillsyn och övervakning..

Den ryska friheten: En studie av förändringen i massmedial frihet från 1985 till 2008

Uppsatsens syfte är att göra en komparativ studie av hur den ryska friheten för media har förändrats under tre olika politiska perioder mellan åren 1985 och 2008 tillsammans med de olika presidenter som personifierade dessa perioder. Arbetet utgår ifrån ramarna av yttrande- och pressfrihet mot bakgrunden av FN:s och EU:s konventioner om mänskliga rättigheter och Dahls demokratikriterier. Fri media spelar en avgörande roll för demokratin. Politiker står genom media till svars för sina handlingar och medborgarna får viktig information och för detta krävs det yttrande- och pressfrihet. Utan rätten till dessa försvinner snabbt den vanliga medborgarens förmåga att delta i, och positivt påverka politiken.

Detektion av temperaturförändringar med hjälp av trådlösa sensornät

Målet med detta examensarbete var att erhålla kunskap om teknik och möjligheter hos trådlösa sensornät. Speciellt undersöktes hur temperaturförändringar kan detekteras med hjälp av ett trådlöst sensornät. Ett sådant nät sattes upp inomhus med enheter som kallas Tmote Sky och som tillverkas av Moteiv Corporation från USA. Enheterna har flera givare och kan kommunicera med varandra via radio. Härefter kommer de trådlösa sensorerna att kallas ?smolk? efter direktöversättning från engelskans ?mote?.

Energioptimering : Resteffektkylning av mellanlager för använt kärnbränsle (CLAB) Oskarshamn

This thesis is done in cooperation with SWECO Energuide in Växjö. They have been assigned by SKB in Oskarshamn to renew their electrical power supply and the ancillary processing systems in their Central provisional storage of spent nuclear fuel, CLAB. Today in the CLAB facility, the spent fuel is cooled down with water pumps, driven by asynchronous induction motors, where the water is regulated by mechanical valves to the desired flow. After the upgrade, the engines will be powered by AC drives that can control the pumps by changing the rotational speed and thus change the water's cooling effect on the nuclear fuel. In this study, I investigated the interference AC drives causes the feeding network and how to go about averting them.

Utborgaren -en studie om SVT:s roll för den sociala sammanhållningen i en svensk demokrati

Sveriges Television kallar sig en TV i allmänhetens tjänst och har en erkänd roll som viktig aktör i den svenska demokratin. I sin roll som public service-företag har SVT en mängd uppgifter att fylla genom sitt programutbud. Public service uppgifter som alla tillsammans skall främja ett demokratiskt samhälle. I takt med att medielandskapet och samhället har förändrats så står SVT:s ar-bete med dessa uppgifter och mål inför nya utmaningar. Vi har i denna upp-sats anammat teorin om att TV-utbudet för public service idag börjat efterlikna de mer nöjesanpassade TV-kanalerna i fråga om programutbud.

Från vilda till domesticerade djur - kan man gå ett steg längre?

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

En ny musikarena utan solister

The music industry has been subject to great changes during the last ten years. The most significant factor contributing to this change is the increasing usage of broadband and thereby the increasing frequency of downloading music illegally. Music piracy and file sharing have caused record sales to plummet. Consumers have now moved on to consuming music in a digital format, not only through downloading but also from streaming music online, an activity partly made possible by social media channels such as YouTube. As the consumption patterns have changed companies within the music industry have been forced to find other sources of income than record sales and they have also needed to find alternate ways to market their artists.
