H?RNERVMOSSANS P?VERKAN P? LJUNGHEDENS ARTM?NGFALD: En f?ltstudie fr?n Sandsj?backas naturreservat

Campylopus introflexus is a moss species that originates from the southern hemisphere and has spread worldwide during the 20th century. Today it is classified as an invasive alien species in many countries, and it has been seen during inventories that it has become widespread in Sweden as well. The purpose of this essay is to contribute to new knowledge about how this moss affects species diversity on Calluna heathlands in Sweden. The study includes both fieldwork and an analysis of scientific literature on the subject, and the question that is answered is if C. introflexus has an impact on species richness in the heather peat.

Ragnar Edenmans kulturpolitiska problematisering: styrning av estetisk bildning och estetisk miljö i statlig socialdemokratisk kulturpolitik 1957-67

This master?s thesis analyzes how cultural policy was problematized in three governmental policy areas; culturalpolicy for the free sector, education policy and popular education policy, during the social democrat Ragnar Edenman?s time (1957-67) as minister of ecclesiasticalaffairs. Earlier research has examined the policy for the free sector, concerning artist?s economic problems. This thesisadds an analysis of the other fields of policy, which were reformed in the 1960?s by the same ministry.

Kvinnor i litteraturhistorien : en undersökning av hur kvinnors skrivande och deras litterära verk beskrivs och värderas i litterära översiktsverk för gymnasieskolan

The purpose of this masters thesis is to examine outlines of literary history for students at upper secondary school from a gender studies perspective. Earlier theoretical work concerning outlines of literary history is sparse. There are three dissertations, but none with an explicit gender perspective. The theoretical approach comes mainly from theories in literary historiography and gender research. Also discussed are the following concepts: canon, literary field and literary valuation.

Studier i parametrisk modellering. 3D-CAD modellering applikationer

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Effekten av frekvenskomprimerande hörapparater på taluppfattningen hos patienter med grava diskantnedsättningar ? En experimentell studie

A pilot study conducted on four patients, which we received from the Sahlgrenska University Hospital, who were all potential candidates for a cochlear implant. We fitted our test subjects with a pair of frequency compressing hearing aids called Phonak Naida V SP during the study and let them evaluate them for about seven weeks. Measurements made with monosyllabic words throughout the study showed significant differences in speech perception (p?0.05) compared to their regular hearing aids in 3 out of 4 cases. De-activation of the frequency transposed function showed significant decreases in 3 out of 4 cases compared to when it was activated.All test subjects were satisfied with the new hearing aids and chose to keep using them at the end of the study..

Distribution of wild boar (Sus scrofa) damage and harvest loss in crop fields

The last decades the populations of wild boar (Sus scrofa) has increased rapidly over the species? entire European range, including Sweden. This is followed by increasing human-wildlife conflicts as a result of the wild boar foraging behavior, causing damage to agricultural crop fields due to trampling and feeding. To be able to minimize damage we need more knowledge of where in the fields the risk of damage is high and what features in the landscape that affect this risk. I analyzed damage distribution in relation to the distance to six different landscape features; forest, road, ditch, building, game field and bait station, in the study area, the Island Mörkö in eastern central Sweden.

Skördemetoder av industrihampa :

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

Design and implementation of a 5GHz radio front-end module

The overall goal of this diploma work is to produce a design of a 5 GHz radio frontend using Agilent Advanced Design System (ADS) and then build a working prototype. Using this prototype to determine if RF circuits at 5 GHz can be successfully produced using distributed components on a laminate substrate. The design process for the radio front-end consists of two stages. In the first stage the distributed components are designed and simulated, and in the second stage all components are merged into a PCB. This PCB is then manufactured and assembled.

Kulturellt relevant socialt arbete? : En fältstudie i en SOS-barnby, Swaziland

The purpose of this study was to examine how SOS Children's Villages as an organization in Swaziland is affected by, and takes into account, the cultural, organizational and societal context in which it acts. Material was gathered through a field study during one month in one of the three SOS Children's Villages in Swaziland. The study has a qualitative approach and is based on the result from 12 semi-structured interviews with village mothers and other representatives from the organization. The other representatives were: social worker, program director, child and youth development coordinator, board member and educational manager. Since this study is both characterized by a specific historical, cultural and organizational context, we decided to connect the postcolonial perspective with an organization theory with focus on the concepts of culture, power and a children?s right perspective.

Resistenta rapsbaggar :

Oilseed rape crops are an important in southern Sweden because of the high intensity of wheat growing. Pollen beetles are the most important pest in oilseed rape and causes often economic losses. Therefore it?s of great importance that we can control the population density, e g by using insecticides if necessary, to avoid mayor yield losses. In year 2000 pollen beetles were numerous in the province of Östergötland. The farmers sprayed with insecticides several times, but with low effects on the beetles. Field trials and laboratory experiments showed that pollen beetles had developed resistance against pyrethroids.
