Habitat preferences and reproductive success forthe threatened longhorn beetle Plagionotusdetritus
Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species reproductive success. The reproductive success was measured in two ways, the larval mortality and the size of the hatching holes.
Nedskrivningsprövning av Goodwill - En kvantitativ
Since the year 2005 listed companies are supposed to use international accounting standards when they set up their group accountancy. One thing that has changed with the new standards is the accounting of goodwill and long-lived intangible assets. Earlier companies were supposed to write of their goodwill during the years they had expected the extra profit to arise. According to the new regulation, an impairment test shall be done annually, as well as when there is an indication of decreased value. According to IAS 36 point 134, the company shall provide information in their accountancy about the impairment test.The aim of this study is to find out if some companies may be willing to reveal less information in their accountancy, and if there are any factors that affect this.
Filter och kapsling för IR-givare
This paper describes the work done trying to diminish the noise present in the signal from an IR-detector. The project was aiming towards two different kinds of applications; heat protection and presence detection. The hypothesis was that the signal-noise ratio would decrease if a filter and a proper installation were used for the detector. Some experiments were executed to determine what kind of filter were the most suitable for each application and how these could be installed. After executing the experiments and evaluate the results we recommend to use a specific filter for each application.
Hållfasthetssortering av plankor med hjälp av röntgendata
The aim of this thesis is to find a statistical model that sort logs according to a predicted modulus of elasticity on the sawn boards. The input parameters for the model are X-ray variables from an X-ray scanner. For some of the log classes sawn at the sawmill it is desirable to have a narrow distribution of modulus of elasticity on the sawn boards. 250 pine logs from five different diameter classes were numbered and followed through the sawmill process. Log data were collected from X-ray and 3-D scanners in the log intake.
Utveckling av processparametrar inom en hårdmetallindustri
This report analyzes and examines a hypothesis for finding a method to optimize thelength of the delubrication process time based on a total charge weight. The work hasfocused on the holding time for delubrication and the total charge weight.An important step in the manufacturing chain of cutting tools is when the greenbodies undergo the sintering process. Today, the delubrication step has the sameprocess time independent of the total charge weight. An implementation of a methodto adjust the delubrication process time would give more consistent quality of thecutting tool´s internal characteristics but also reduce the time course of the sinteringprocess. In the present project two methods for this goal were tested, thedevelopment of an algorithm and a weight interval subdivision with associateddelubrication process times.During delubrication a pressure increase is observed due to the decomposition of thePEG in the powder mixture.
Kvalitetssäkring och processtyrningav ytstruktur på lackerat objekt
To be allowed to sell Z-suspended vehicles with dipped beam Xenon or LED lighting, Scania have to develop automatic headlight level control. This master?s thesis aims to be the foundation to that development.The thesis consists of several parts; a market analysis of how competitors to Scania and the general vehicle industry solve this problem; several available principles for detecting the amount of control needed; the construction of a test station for sensors, a control unit and components connected controlled by the control unit; a further theoretical and practical development of one principle ? one rotational sensor connected between the chassis and the back drive axis; a state flow model programmed in Simulink that produces the control signal for the headlight leveling from the sensor input.Lastly the thesis gives some recommendations to the further development and implementation of automatic headlight level control on Scania vehicles..
Demand and perception of fertilizer : among small-holder farmers in Kenya
Hunger is a problem in some parts of the world (www, FAO 1, 2012). The lack of food is often a result of insufficient knowledge in soil fertility management (Röing de Nowina, 2012). Ongoing hunger and malnourishment are quite prevalent in Sub-Saharan Africa and are often combined with poverty (www, FAO 1, 2012). Farming is the most common occupation in this area and the farms are often small-scale farms with subsistence crops and a few cattle. The farmers who operate these small-scale farms are economically a weak group.
Förintelsen i historieböckerna : En jämförande läromedelsstudie
This study of Swedish history books for grade 9 will examine and compare what the books say about The Holocaust and how it is presented. I analyse how the books present The Holocaust and how it is portrayed. I use questions to evaluate the content of the texts and thereafter I compare them to each other. My hypothesis is that history books are affected by the society in which they are written. Therefore I think that comparing books from different years, I will be able to see a difference between the books when it comes to the way they choose to present The Holocaust.
Gotlands solelpotential
The aim of this thesis is to investigate the electric solar potential on the Swedish island Gotland. The Gotlandic habitations have been divided into four house categories. For each category energy demand, roof area, geographic orientation androof tilt have been decided. Solar radiation data have been collected from the Swedish solar radiation model STRÅNG (STRÅNG, 2012).The buildings characteristics and the solar radiation have been used as input values in common solar formulas, the solar potential for each building category have been summed up to a total electric solar potential for the region.The electric solar potential on Gotland was calculated to 242 GWh/year with solar data from 2010. Gotlands largest city, Visby, is marked as cultural heritage by UNESCO (UNESCO, 2012).
Vi lämnar spår på Internet : Integritet i relation till loggning på UpUnet
This study focuses on the integrity of students at Uppsala University that has used the university?s network, UpUnet. We?ve studied their opinions with the use of questionnaires that cover questions related to privacy and awareness about logging of data traffic.The results showed that more students than our hypothesis suggested were unaware of the surveillance on the network, and the majority of these also had a negative opinion towards logging of data traffic. However, we found that there were several relations between how the students responded on our questionnaire, and we?ve presented these in the analysis chapter towards the end of the essay..
Blockpolitik i riksdagen : Har riksdagsledamöterna förvandlats till röstboskap?
This thesis aims at studying the development of the party cohesion and oligarchichaltendencies in the party groups of the Swedish national parliament, riksdagen, after theintroduction of two clear block coalitions during the years 2006-2010.The result of the cohesion during these years has been compared towards the years 1998-2006.The research method being used has been 18 semi structured interviews with member of the parliament during the examined years. The main findings show an increment of both the cohesion and the oligarchical tendencies after the block coalitions during the years 2006-2010. The result verified therefore also the two originally stated hypothesis..
Iron bioavailability and pro- and prebiotics
Iron deficiency is one of the most frequent micronutrient deficiencies around the world. Low iron bioavailability simultaneously with a high iron requirement is a high risk factor for developing iron deficiency. Probiotics are microorganisms that confer a health benefit on the host. Prebiotics are oligosaccharides which provide a health benefit on the host due to a positive modulation of the microflora in the gut. The aim of this paper is to evaluate if there is a connection between pro-and/or prebiotics and iron bioavailability.
Kan regional påverkan från Danmark förklara Sverigedemokraternas valframgångar i Skåne?
ABSTRACTCan Danish experience explain why Sverigedemokraterna had a higher support among voters in Skåne, than among other Swedish voters?Essay in Political Science, C-levelAuthor: Jenny WoodTutor: Gregg Bucken-KnappAutumn 2006/ Spring 2007The key question of this essay concerns the outcome of Sweden?s latest election. When all the votes where counted, the county of Skåne showed an exceptionally high support for the right wing nationalist party Sverigedemokraterna. Why then, did Sverigedemokraterna have a higher support among voters in Skåne (as part of the larger and transnational Öresund region), than among other Swedish voters? My hypothesis is the following: the regional interaction within Öresund has not only had positive effects concerning the values that the people of Skåne hold.
Ett ledarskapsperspektiv av innovation och knowledge management : - En kvalitativ studie
I organisationer idag bo?rjar det bli mer och mer centralt att fokusera pa? medarbetarnas innovationsmo?jligheter och kunskap. Organisationer bo?r numera fokusera mer pa? den tysta kunskapen och go?ra denna explicit fo?r att utnyttja den fulla potentialen till innovation. I dagens organisationer kra?vs det a?ven att medarbetarna va?gar arbeta o?ver gra?nserna och att ledningen tydliggo?r att allas input inom organisationen va?rderas likva?rdigt.
Att driva etablerad Buddhistisk och Muslimsk verskamhet i Karlstad kommun : De verksammas uppfattning om möjligheter och svårigheter som religiös i Karlstad
I wanted to focus this essay on the operative?s perspective of running religious organizations in the city of Karlstad and to see positive and negative aspects of their day-to-day life working with their organization, following up with a comparison of the difference and the similarities between those groups. After delimitating which groups I was going to examine, I implemented a qualitative study of four people, from two different religious groups, whom I performed interviews with. My method of performing these interviews and understanding the perspective of the informants, I had a semi structured interview guide along with a recent study that was opting for similar conclusions, only in a different county and with different input perspective. The result of my study showed a difference in establishment of their region but with a lot of similarities in problems with their religious and structural premises.
