Det virtuella kontoret : En litteraturstudie i möjligheter och utmaningar med att använda 3D kollaborativa virtuella miljöer inom distribuerad systemutveckling

Distributed system development is a common occurrence in today?s technological and global world. Because the consequences of its geographically distributed nature it creates barriers between people that affects their communication and collaboration efforts in the distributed context. Despite a lot of technological breakthroughs over the last decades and the occurrence of video-conference applications and other tools for communication and collaboration, cultural and geographical issues have so far not yet been completely resolved. In this study I have made a literature study over distributed system development to form a set of central factors that affects the distributed development process.

Skademönster på Gotland : Kontaktorsak, skadeplats och skadeorsak med fokus på ålders ? och könsskillnader

Injuries are considered to be a major public health issue. More than 4600 people die each year and 10 % of all hospitalization in Sweden is related to injuries. The cost in a societal perspective is estimated to 59 billion a year. Injuries are possible to prevent. However it needs knowledge that the injury has occurred and the surrounding circumstances.

Förekomst av Chlamydia/Chlamydophila spp hos gris med och utan konjunktivit.

ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.

En osynlig risk : studie av människors inställning till radonrisk och åtgärder

Approximately 400 people in Sweden die each year by lung cancer caused by radon gas. Authorities have in recent years invested big resources and organized campaigns to encourage people to take action against high occurrence of radon in residences. With low frequency of applications for radon allowances as the main measure, a lot interprets on a very low commitment. The purpose of this thesis is to investigate the reasons for the low commitment among people. The study is based on a questionnaire survey sent to 444 house owners in Uppsala.

Duk i buk : Functional Resonance Accident Model i en vårdrelaterad kontext

Ett stort antal människor dör på grund av skador som de fått inom vården och som hade kunnat förebyggas. Det finns siffror som pekar på att dessa vårdskador överskrider antalet döda i trafiken. Vid Östergötlands landsting finns sedan år 2005 en fast enhet som arbetar med patientsäkerhet. En av deras uppgifter är att, tillsammans med berörd verksamhet, utföra händelseanalyser inför anmälningar av Lex Maria-fall. Den analysmetod som används av patientsäkerhetsenheten är uppbyggd på en epidemiologisk olycksmodell.Syftet med denna studie har varit att använda analysmetoden FRAM (Functional Resonance Accident Model), som är en systemisk analysmetod utarbetad av Erik Hollnagel, i en vårdrelaterad kontext, någonting som inte har gjorts tidigare.

?Alltså man kan typ rätta sig själv med båda språken? : Tvåspråkiga elever resonerar kring sina språk och språkens nytta i skolan.

The purpose of the essay is to study and create understanding to the bilingual students' perspective on their linguistic skills and the use of them as resources in a scholastic context. A qualitative method has been used to collect empirical data, based on the experiences and perspectives of the students. Bilingualism is defined and past research, which has shown how their bilingualism has influenced them, has been linked with this study. Definition of mother tongue and the meaning of mother tongue tuition for student immigrants' development have been discussed. This research has shown that the students feel their bilingualism is a natural occurrence.

Uptake of 137Cs by fungi and plants due to potassiumfertilization in Heby municipality in response to theChernobyl nuclear accident

The fallout from the Chernobyl nuclear accident resulted in large deposits of caesium, iodineand strontium as well as noble gases in various parts of Sweden. 137Cs has a radioactive halflifeof about 30 years and is therefore one of few radio-fission products remaining inmeasurable quantities in the Swedish soil. Radiocaesium behaves similarly to potassium insoil-plant systems and is easily absorbed by plants. It is important to understand how 137Csbehaves in different ecosystems in order to minimize the risk toward humans.The aim of this study was to determine how potassium fertilization influences radiocaesiumcontent in different forest plants and fungi. Potassium fertilizer was spread once in 1992 withapproximately 200 kg KCl per ha.

Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Wildlife Detection Network

Traffic accidents where wild animals are involved represents between 60 and 80 percent of all reported accidents, depending on location in Sweden. In a country like Sweden, with a lot of forest, there is always risk of a collision with a wild animal. Imagine if you, as a road user, had the possibility to receive warnings when the risk of an accident according to statistics is extra high.Wildlife Detection Network is a wildlife warning system with an information service, which makes the whole concept unique. When an animal is approaching the road, it is registered by sensors, and warning lights along the road are lit to inform drivers of the potential danger. In conclusion, this is a direct warning to all drivers on the road where the system is placed.When an animal is registered by the sensors, information containing time, date, weather circumstances and coordinates are sent to a database.

Occurrence of Verotoxin-encoding phages in mussels grown downstream the sewage treatment plant in Lysekil

The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.

Kartläggning och jämförelse av träning i neonatal återupplivning på svenska sjukhus

The purpose of this study was to survey the occurrence of and obstacles to team training inneonatal life support in Swedish hospitals and, accordingly, to compare university hospitalswith other hospitals. The study included all the managers in 37 pediatric wards whoparticipated in telephone interviews with the aid of a questionnaire. The results showed that81 % of the Swedish hospitals that have a paediatric ward train the staff in neonatal lifesupport. All of the university hospitals and 74 % of the other hospitals are running training insome form. The methods of training varied and so did the occurrence of training.

Vattenkvalitet och risker vid ändrat intag för vattenförsörjning i Västerås

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :

Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

Urspårad nyhetsrapportering : En kvalitativ textanalys av en lokal och en rikstäckande tidningsrapportering av tågolyckan utanför Kimstad

The purpose with this study is to examine how the media coverage of the train accidentoutside Kimstad, on the night of September 12th 2010, was framed in one local (Norrköpingsnyheter) and one national newspaper (Expressen) and how the coverage of the accident wasdifferent in the local newspaper compared to the national newspaper.The material is 12 articles within a fixed time limit which is from September 13th toSeptember 15th. The material consists of six articles from each newspaper.The method we use a qualitative text analysis with its basis in medialogic, news value andframing theory.In the essay?s analysis we show a synthesis of both newspapers coverage of the train accidentoutside Kimstad and how they stand in relation to the theory of news value and we end with aterminative comment about the results.The conclusion shows that the coverage of the event was different in many ways. Expressenuses a more dramatic framing and a more sensational language which describes the eventmore badly than it was. NT uses a more informative and objective information which almosttrifles the event but which informs about relevant information for the locals.

Environmental variables determining the occurrence of the red-listed Carbonicola anthracophila and C. myrmecina in boreal forests

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.
