A screening for Schmallenberg virus among sheep, goats and cattle in Zambezia province, Moçambique : and preparations for a metagenomic survey of virus in mosquitoes

As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming, leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs. Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.

Analysmodellen - en variation i tillämpningen?

The purpose of our essay is to examine if variation exists in the way that auditors try their independence, this so called analysis-model. We will suggest some factors that influence the way auditors practise the analysis-model. The institutional theory predicts no differencies since the normative pressure could be expected to be severe. But we found that among other things people?s qualifications, personalities and audit firm?s size and age influence the way auditors try their independence.

Träbroar för järnvägstrafik

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.

Omfattningen av icke avverkade områdeni samband med slutavverkning :

This final thesis is performed on commission of Torsby forestry administration, Stora Enso Skog. Stora Enso Skog is one of the major forestry companies of Sweden. The main business area is located in and around the region of Bergslagen. During the last decade the practice of forest management has rapidly changed due to a new forest legislation. The new law has resulted in that the production goal is equal to the environmental goal within forestry.

Skogsvård hos privata skogsägare : vilka åtgärder utförs och av vem?

Many participants in the Swedish timber market procure raw material from private forest owners. They often also offer forest services to ensure reforestation after final felling. Selling silviculture services can be a part of creating a long term relationship with the landowner for future timber purchases. The Swedish Forest Agency monitors forest rejuvenation results in the entire country. In the latest survey (2006 - 2008) the proportion of approved regeneration area was 78%.

Urban vindkraft : Vindkraftsprojekt Järvafältet & vindkraft i Sverige

Wind power is an energy source that is becoming increasingly popular in Sweden and around the world. The establishment of large wind farms supply and contributes to energy production within grid in search of a more sustainable energy production. Wind power is becoming more popular and opens up new areas of implementation. More cities are starting to use small-scale urban wind power, everything from full-scale work for a little less work adapted to the villas. Sweden has high goals regarding the production of green electricity and the work which deals with the conditions Sweden plays in achieving those goals.

De Nordeuropeiska långhögarna : Hus för de döda

The discovery and excavation of Long Barrows has been one of the major developments in the understanding of the Early Neolithic in Southern Scandinavia during the last decade. The Long Barrows are one of the oldest monumental burial forms that we see in northern Europe in the neolithic. They are also the first example of a common idea that is connected to a monumental burial form amongst the people. In this essay I attempt to show that there actually are quite a large number of Long Barrows in Scandinavia that show similarities with Long Barrows in well-known areas such as Kujavia (Poland) and Pommerania (Germany/Poland), in both architecture and location in the landscape. I also scrutinise some theories regarding this phenomenon and discuss, and i some cases, criticise them.

Leanorienterad flödesutveckling : av kärntillverkningen på Affärsenhet Cylinder ASSA AB

Business unit Cylinder at ASSA AB in Eskilstuna are having problem with frictions in their production process. Changes are occurring and older products along with machineries are phased out and transferred to low-cost countries. This opens up possibilities to at a larger extend customize physical flows after production flows. The authors where given the task to analyze the production and find problem areas to improve and to give suggestion on how Business unit Cylinder can work to optimize their production flow.The aim of the thesis work is to come up with suggestions on how to reduce the lead time in production and how the tied up capital can be reduced. In more detail the task included to find problem areas that are counteracting an effective flow, give solutions on new flows for the production of the cylinder core, give suggestions for new stock points for the production and how the production shall be managed and controlled.During the last twelve months ASSA AB has sold over 700 different types of cylinder cores, and the product range is very wide.

Analys av fingeravtryck

This report describes a system for verification of fingerprints against a previous created template. It describes how and why a fingerprint image must be processed before it can be used to either identify or verify a person. The method is based on special features of a fingerprint, called minutiae points. The whole process from image to matching is described, every step in the process with image enhancement, binarization, thinning and how to find the minutiae points. Also what false minutiae points are, how they arise, why they deteriorate the result, and how to handle them, is discussed.

Alla vill beta men ingen vill bränna : skogshistoria inom Särna-Idre besparingsskog i nordvästra Dalarna

In this work I have tried to reconstruct the forest history within Särna-Idre forest common in northern Dalarna from the 19th century until present time. The Särna-Idre region has been an extensively used landscape for a long time. Pollen which indicates grazing has been found in samples orginating from the 10th century. Early travellers from the 18th and 19th centuries seem to have been passing trough a "used" landscape. Burned forests on naked ground are described as common. Also large areas are mentioned as undisturbed with lots of large trees, snags and dead wood.

Naturen som pedagogisk resurs : Fritidspedagogers syn på utemiljön

The purpose with my project is to evaluate how Recreational Leaders use the outdoor environment, how much they use it and why. My method was to assemble the surveys which were answered nationally by Recreational Leaders. During my project I have investigated Recreational Leaders view on the outdoor environment by reviewing a survey. Those who answered the survey find that the desire to use the outdoor environment exists; they think that the benefits of moving the teaching process outside are plenty. The children receive fresh air, they get to practise manual ability and gross motor functions, stay healthy and are able to use their imagination and creativity.

Gymnasieskolan i förändring - hur väl anpassade är skolbiblioteken?

The general view of learning has dramatically changed during the last two decades. Today we talk about learning for life and educate to meet the demands of the information society. This new view forces us to constantly relearn and develop new knowledge ? something which has resulted in large restructuring within the upper secondary school. New forms of teaching, where the pupils are given the opportunity to a more active search for knowledge, is developing.

Förväxlingar av ord i testet FB S/N +4

It is always more demanding and the risk for misunderstanding increases when communicating in noisy environments. The confusions and the mistakes that occur when speech is disturbed are very interesting and happens constantly. The purpose of this study was to examine speech recognition results from the test PB S/N +4 and find out which confusions that are made by the normal hearing and by the hearing impaired persons in the speech lists 3 and 4, and also analyse the mistakes from a phonetic perspective. Ten normal hearing and 50 persons with impaired hearing participated in the study. The people with impaired hearing were divided into two groups; DTMV 40 dB HL.The results were compared between the normal hearing and those with impaired hearing.

Anslaget till Handslaget-vad fick vi för pengarna? : en utvärdering av samarbetet med skolorna i Gästrikland andra året

AimThe Swedish government has allocated a milliard Swedish Crowns on the project ?Ett handslag med idrotten?, (A handshake with sports), to make it possible for more children to participate in sports. The project goes on for four years and my work is an evaluation of the projects that have received fundings from Gästriklans Idrottsförbund for the second year. One aim is to see how many pupils that have been involved with the projects and especially the numbers of pupils earlier not active in a sport club and the number of girls. It is interesting to see what?s in common in the sport clubs that have had a large number from those two groups.
