I syfte att undersöka psykometriska egenskaper hos Affektiv självskattningsskala (AS-18) fyllde 88 patienter med diagnos bipolär typ I (N=46) eller typ II (N=42) i självskattningsskalorna AS-18 och MADRS-S vid två tillfällen med en dags mellanrum. Principalkomponentsanalys för AS-18 genomfördes med extrahering av två komponenter. Items laddade i de delskalor de tillhörde. Intern konsistens mättes med Cronbachs alfa och överensstämmelse med Cohens kappa. Test-retest-reliabiliteten beräknades.

The aim of this study was to detect antibodies in swine serum against proteins in soy beans, wheat, oat and barley. Two methods were used: agar gel immunodiffusion test (AGID), and SDS-PAGE followed by immunoblotting. The sera examined originated (I) from piglets younger than one week (negative control), (II) pigs from a feed trial with soy bean in a herd with PMWS, and (III) pigs inoculated with Brachyspira hyodysenteriae and Escherichia coli after being fed with soy. The AGID-test was negative concerning all examined sera which were analysed against proteins in soy bean, wheat, oat and barley. In the experiment based on immunoblot antibodies were demonstrated within all three groups of examined pigs.

Around 85 percent of the total population in Sweden today lives in an urban environment. This means that the nature within the urban areas has come to play an important role for the human well being. At the broader picture, the nature within urban areas is profitable in many ways. It is therefore important for the municipalities around in Sweden to work for sustainability within the urban areas. Linköping adopted an environmental policy, in year 2001, from the delegate of the municipality.

AbstraktKonditionsträning aktiverar stora muskelgrupper och ökar aerob och anaerob energiomsättning. Bikarbonat (bi) har stor betydelse för gasutbyte för att konditionsutövare inte ska bli utmattade genom försurning i kroppen. Forskare har därför undersökt om ett tillskott av bikarbonat kan leda till ökad prestation vid konditionsträning.Syftet med studien är att undersöka om bikarbonat kan utöka fysiskt aktiva mäns prestationsförmåga.Vi har använt oss av en randomiserad crossoverstudie. Manliga deltagare (n=13) undersöktes i studien (ålder 27 ± 9, längd 183 ± 8 cm, vikt 81 ± 14 kg). Deltagarna utförde tre Coopertest vid tre separata tillfällen.

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products. The report is a thesis work of a bachelor mechanical engineer program, in the field product development and design.The project is a study of the development opportunities within drive belt for a gear driven gearbox to one of Husqvarnas petrol powered hedge trimmers. A big part of the project was also to find combinations of materials for all components in the gearbox, to reduce weight and maintain or improve the performance of the system. Belt drive was of interest to investigate as an alternative solution to the current design that can reduce wear on the system at a performance test performed in the company before the product is released to market.

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.

Att perceptuellt uppfatta och identifera lukter påverkas av en rad olika kortikala system och kognitva förmågor. Syftet med föreliggande studie var att undersöka huruvida personer med afasi har en luktförmåga som skiljer sig från normalpopulationen och ifall en afasiproblematik påverkar de faktorer som normalt involverar luktförmågan.         I studien medverkade tio försökspersoner, sex män och fyra kvinnor. Personerna hade varierande grad och typ av afasi och var mellan 42 och 76 år. Deltagarna delades in i åldersgrupper där två personer klassades som yngre och åtta som äldre. Samtliga testdeltagare genomförde två olika lukttest: Odor Threshold Test (OTT), och Swedish Odor Identification Test (SOIT).

This study investigated the relation between Extraversion and Conscientiousness with job satisfaction and job selection in the two occupational groups of telemarketing and administration. The study also set out to explore the relation between social desirability as assessed with an Implicit Association Test (IAT) and total reaction time on the IAT. The questionnaire was administered over the Internet to forty-one subjects (24 women and 17 men) in the age range 16-65. Results indicated that people working with telemarketing tend to be extrovert while people working with administration often are conscientious. Job satisfaction correlated with Extraversion in the telemarketing group.

To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Mitt examensarbete behandlar förskolepedagogers syn på den fria leken. Problemet är ofta vad pedagogerna ska lägga i ordet fritt. Jag har dock kommit fram till att de flesta förskolepedagoger är relativt samstämmiga vad gäller friheten kontra de regler som behövs i den fria leken, men att det finns oenigheter om t.ex. var man ska dra gränsen när barn leker krig och hur tillåtande man ska vara när det gäller de mer fysiska lekarna, som att springa och jaga varandra, brottas och när barnen, enligt pedagogerna, är högljudda. Jag har valt att använda mig av kvalitativa intervjuer som metod i mitt examensarbete och spelade in intervjuerna, med sex förskolepedagoger, på min Iphone 5, för att sen skriva ner dem ordagrant och efter det övergå till att sammanställa resultat och analysera intervjuerna. Jag har analyserat intervjuerna utifrån mina frågeställningar: > Vad innebär fri lek i förskolan, enligt pedagogerna? > Vad anser pedagogerna att syftet är med den fria leken? > Vilka regleringar finns kring fri lek och vad kan dessa innebära? I mina teoretiska utgångspunkter vid analysen har jag använt mig av såväl Vygotskij och Dewey, som av moderna forskare som Pramling Samuelsson och Knutsdotter Olofsson. Efter att ha gjort detta arbete har jag kommit fram till att samtliga pedagoger ser den fria leken som det viktigaste på förskolan.

This thesis, designed as a case study, is about complications concerning conservation of a decorative oil paint on lime plaster from the drawing-room in Mostorp castle sited in the county of Halland in south-west of Sweden. The building was built 1878-80 with an exterior of granite. The interior walls were made of clay bricks, lime mortar and lime plaster. The oil paint is applied to a layer of putty. The combination of different materials, which are organic and inorganic, affects the movement caused by internal and external stress.

In order to understand user behaviour and navigation patterns, user logging is today widely used in analysis and development of user interfaces. These user logs tend to be quite many and can contain a lot of different data. A big issue is how to process and display this data in a perspicuous way to the stakeholder. This study is about how to develop a prototype to handle this issue. It was solved by various methods from human-computer interaction.

This project is about development of virtual drums for iPhone and iPad. The project aims to provide the company Toontrack AB with a good foundation to build drumbased apps. The focus has been on getting a quick response when playing and that user interfaces should be easy to use, intuitive and customizable. The result is impressive and both audio and graphics are of excellent quality thanks to good collaboration with Toontrack, that previously has developed drum-based software. The drum kit offers a variety of articulations and even the ability to play various dynamics, although the screens are not pressure sensitive..
