Surveillance of Geomyces destructans in Swedish bats and Bat Hibernacula

White-Nose Syndrome, WNS, is an emerging fungal disease in the Northern American bat population causing mass mortality in infected hibernacula. Geomyces destructans is a newly discovered psychrophilic fungus causing WNS but the pathogenesis and epidemiology of the disease is not yet fully clarified. Geomyces destructans has been found in Europe but has not been a cause of mass mortality there. This study is the first investigation done to see if G. destructans is present in Sweden.

Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Klassificering av allvarlig kronisk parodontit: En jämförelse av fem olika klassificeringar utifrån prevalensen av allvarlig kronisk parodontit i en population från Kalmar län

Bakgrund: Parodontit definieras som en inflammationssjukdom orsakad av en obalans mellan bakterier i den dentala biofilmen och värdens immunförsvar. Det saknas en enhetlig klassificering för allvarlig kronisk parodontit i epidemiologiska studier; internationell data avseende prevalens och utbredning av kronisk parodontit är därför svårtolkade. Det saknas studier som har undersökt huruvida och hur mycket variationerna av klassificeringar påverkar utfallet, det vill säga prevalensen av allvarlig kronisk parodontit. Syfte: Syftet med studien var att utvärdera skillnaderna mellan fem olika klassificeringar av allvarlig kronisk parodontit: (i) Konsensuskonferensen 1999, (ii) American Academy of Periodontology and Centers for Disease Control and Prevention (AAP/CDC), (iii) European Federation of Periodontology (EFP), (iv) Jönköpingsstudien samt (v) Skånestudien. Material och Metod: För att kunna jämföra klassificeringarna studerades prevalensen av allvarlig kronisk parodontit utifrån en population i Kalmar län.

Begåvningsnivå och psykiska problem - en undersökning av en kohort tvångsvårdade flickor och kvinnor

This study describes the intellectual ability of a cohort consisting of 120 young women in compulsory care at a SiS institution in Sweden, tested and analyzed between January 2001 and May 2005. The women have been tested with the intelligence tests WISC-III or WAIS-R, as well as the personality trait tests BCT, CMPS and SCL-90, and the personality disorder test SCID-II. This material has been analyzed to investigate how these women's intellectual ability relates to other factors. The analyses show that the main difference between the women of this study and the normal population is their level of intelligence and presence of personality disorders. The IQ level of these women is statistically proven on an average one standard deviation lower than the normal population.

Integrering av 3D-fysikmotor i simuleringsramverk för telekrigdueller

Syftet med det här arbetet har varit att välja ut och integrera en lämplig fysikmotor med öppen källkod i simuleringsprogramvaran EWSim på Totalförsvarets Forskningsinstitut (FOI). EWSim är ett ramverk för duellsimulering i olika telekrigsscenarier. Teorin bakom fysikmotorer och några vanliga tekniker för fysiksimulering har beskrivits kortfattat. Tre fysikmotorer har presenterats och utvärderats med avseende på lämplighet för integrering i EWSim.Fysikmotorn Bullet valdes ut och integrerades i simuleringsprogramvaran. En av de huvudsakliga slutsatserna av arbetet är att fysikmotorer som Bullet mest kan bidra med ökad visuell realism i EWSim.

Äldres erfarenheter av aktiviteter i ett socialt sammanhang. En narrativ studie om den åldrande människan

There is no general aging process therefore should health efforts directed at elderly population based on each individual as a unique person with specific needs. When aging becomes a fact not generally decrease the lust and the desire to be active but it is perhaps more about the body's ability to keep up on what the head wants. Therefore the range of activities towards the elderly population requires some adjustment that can partly be achieved by taking some of the older people?s experiences. The purpose of this study was that by the older people?s experiences of organized activities in a social context to illustrate how they perceive their participation.

"Folk är inte lika för att dom kommer från Sudan" : en översikt av förekomsten av familjer med annan kulturell bakgrund vid Familjenheten i Lund

The purpose of this study was to, using statistical analysis, investigate to what extent families of a different cultural background have participated in family therapy and other family treatment programs at Familjeenheten in Lund. With questions regarding the goals of treatment, and the importance of cultural competence in the treatment process we have let two unit managers comment on the statistics. The population of the study is too small to allow general conclusions to be drawn, however, we have been able to ascertain that families of a different background are over-represented relative to their percentage of Lund´s population. Familjeenheten has no statistical record of ethnicity and the interviewed persons express no certain importance in the families´ cultural origins. They express no need to develop special treatment methods that take the clients´ cultural background in regard as they feel that so many of family issues are universal.

Identifikation av icke-representativa svar i fra?geunderso?kningar genom detektion av multivariata avvikare

To United Minds, large-scale surveys are an important offering to clients, not least the public opinion poll Va?ljarbarometern. A risk associated with surveys is satisficing ? sub-optimal response behaviour impairing the possibility of correctly describing the sampled population through its results. The purpose of this study is to ? through the use of multivariate outlier detection methods - identify those observations assumed to be non-representative of the population.

Svininfluensan : en kritisk diskursanalys av medias rapportering

Media has the power to influences society. Some call them the third power of a state.

These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

Jämförelse av den individuella vertikala CD-kvoten mellan höger och vänster öga hos en normal population

Syfte: Studiens syfte var att ta reda på om det fanns någon individuell skillnad i vertikal CD-kvot (cup/disk-asymmetri) mellan höger och vänster öga hos en normal population. Metod: Ett biomikroskop och en volklins (+78D) användes vid bedömningen av synnervspapillen. Papillens (diskens) och cupens vertikala storlek mättes genom justering av ljusspaltens höjd på biomikroskopet och de båda värdena lästes sedan av från spalthöjdsskalan på biomikroskopet. CD-kvoten räknades ut på höger respektive vänster öga genom att cupens uppmätta värde dividerades med diskens uppmätta värde. Därefter gjordes en jämförelse av den individuella CD-kvoten på höger och vänster öga.
