Exosomes as a potential mechanism of intercellular spread of prion protein

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Barns erövrande av litteracitet i den fria aktiviteten - miljöns och materialets betydelse

The aim of this study is, from a norm-critical approach, to find, investigate and analyse human representation in the visual culture of one preschool in order to understand if the children enrolled are represented or not. The research questions are: In what ways is there imagery of human representations in images and materials designed for play? What skin-colors and origins are dominant in the data collected?We carried out a qualitative study in the form of visual ethnography. This method allowed us to use a combination of different data collection tools such as photography and ethnographic field notes to collect our data. The photographs we took of images and material used for play, was then analysed through semiotic picture analysis.

As a step in their improvement efforts, focus was directed ondeveloping the company's fixtures for machining.Efforts were focused on two main objectives: to develop a complete proposal on afixture which leads to a more rational use of an assigned part and also form general design advice for development of fixtures in the future.During the work progress, discussions have been made with experts at International Aluminum Casting within the field of fixture design. The objective was to obtain sufficient knowledge about the underlying problems with the current fixture for the part. At this stage of the thesis, a number of essential criteria for fixture design were produced.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

This graduate thesis contains the first claw health survey made on Swedish sheep. The chief objective was to give an overview of sheep claw diseases and to assess claw health in adult sheep.

Visuell informationshantering i tunga fordon : Behovsanalys och förslag till förbättringsåtgärder

The flow of information in road vehicles intensifies as new techniques develop. Informationsources such as cell phones, navigation equipment and radios demand the driver?s attentionwhile he or she must stay focused on the road to perform a safe driving. Today the visualinformation inside the vehicle is mostly located on the dashboard, which forces the driver tolook down when shifting attention between the environment outside and the informationinside the vehicle. One way to avoid this is to useHead-up Display (HUD), a technique thatprojects information in the visual field of the user.This master thesis has been performed in cooperation with Scania CV AB, a world leadingtruck producer.

This study investigates the main question ?How can the small, blue spring bulb genera Chionodoxa, Puschkinia and Scilla be used in Swedish outdoor settings, with main focus on the genus Scilla?? This is done by answering four sub-questions: Which of these Scilla-species are hardy in Sweden? Which are their characteristics and habitats? What does their history of application look like? What is commercially available today? The aim of the work has been to make a survey of hardy and available Scilla-species, their character-istics, field of application and history.
