As to now, no study has been made of the mica tempered pottery found along side the asbestos tempered pottery in Norrland during the Bronze Age and Early Iron Age. Its Occurrence has previously only briefly been noted in a few published works and the dating and geographical distribution of mica tempered pottery in the north of Sweden has to a large extent been unknown. This paper aims to compile the available information about this type of pottery and the locations where it has been discovered in order to date and explain the Occurrence of mica tempered pottery in Norrland. It's also suggested that the Occurrence of mica tempered pottery is connected to the spread of the early metalwork from the east to areas that today makes up the north of Norrland..

Reduced tillage has increased in Sweden during several years, primarily to decrease costs andincrease efficiency in crop production. Despite this, mouldboard ploughing is still the mostcommon primary tillage method on most farms. The aim with this thesis was to compare theuse of pesticides and the Occurrence of weeds on ten farms in Skåne and ten farms inMälardalen that use different soil tillage systems. The object of the study was also to clarifywhy the farms had chosen their specific soil tillage system and the consequences it has had onweed Occurrence and use of pesticides. The result showed a slightly higher use of pesticideson the farms that use reduced tillage.

Dead wood is important for many species. The amount of coarse dead wood (diameter >10 cm) is much lower in managed forest than in unmanaged forests. Stumps constitute the largest proportion of the volume of coarse dead wood in managed forests. Since stump harvest for biofuel may increase, the amount of dead wood will decrease even more, which may threaten biodiversity. The first aim of this study was to compare the amounts of fine woody debris (FWD, .

Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the Occurrence of the saproxylic beetle Upis ceramboides. This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very rare and decreasing, and Norrbotten where this study was conducted.

This study examines work relations on a real estate agency. My interest is to examine how real estate agents apprehend their work relations, and how a recession can affect these relations. Previous research shows that the Occurrence of competition in groups decreases the motivation to cooperate. A different research illustrates that reward interdependence is important to performance, and that task interdependence drives observed cooperative behavior. The study contained six interviews with real estate agents working on commission.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage Occurrence.

It is well known that dogs often have Helicobacter spp in their stomach. The importance of these bacteria in the development of gastrointestinal disease in dogs is still unknown. In humans, Helicobacter pylori is a causative agent of chronic gastritis and gastric ulcers. In contrast to humans, dogs seldom harbour naturally acquired H. pylori.

Abstract  The importance of the co-Occurrence of callous-unemotional traits and impulsivity concerning aggressive acts was examined by a survey. The participants consisted of 1478 Swedish youth. Three groups with extreme scores on callous-unemotional traits and impulsivity was identified.  The group scored high on both was more prone to show higher levels of aggressive and conduct problems behavior compare to the other groups. The aggressive and conduct problem behavior was shown at higher level in all examine variables. This study highlight that impulsivity can identify extreme aggressive individuals, without taking HIA (Hyperactivity, Impulsivity and Attention) problem as a entirety, to account, if shown with callous-unemotional traits. Keywords: Callous-unemotional traits, impulsivity, aggressive, conduct problem, youth, co-Occurrence..

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.

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.

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.

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.

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.
