Diversitet hos jordlöpare (Col: Carabidae) i hävdade strandnära gräsmarker :

Diversity of ground beetles (Col: Carabidae) in managed riparian grasslands. The carabid community in moist seminatural grasslands was studied at three different sites in mid-Sweden. Pitfall trapping was carried out during six weeks in spring and early summer 2003. Eight transects, each containing seven pitfall traps, were placed in three different management regimes, either late or continous grazing, or meadow. The species composition was analysed by ordination analyses, i.e. DCA and CCA.

Efficient Frequency Grouping Algorithms for iDEN

This Master?s Thesis deals with a special problem that may be of importance when planning a frequency hopping mobile communication network. In normal cases the Frequency Assignment Problem is solved, in order to plan the use of frequencies in a network. The special case discussed in this thesis occurs when the network operator requires that the frequencies must be arranged into groups. In this case the Frequency Assignment Problem must be solved with respect to the groups, i.e.

Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

Hållbart jordbruk inom vattenskyddsområde : En studie om Sverige, Danmark, Frankrike och Tyskland

To guarantee protection of our drinking water, water catchment protections are established. These are divided into three different zones and in the first zone it is most likely that an activity, such as agriculture, will contaminate the water resource. Hence the activities are strongly regulated or banned. The EU communion is working towards a sustained water quality through several directives; Nitrate Directive, Waterframwork directives and Sustainable use of pesticide directive. The main purpose is to regulate the diffuse pollution from agriculture.This thesis is about how Denmark, Germany and France are working towards a sustainable agriculture within water protection areas.

Framing och epidemier : En studie av framing i relation till fiktiva och reella epidemier

The present study aimed to replicate Tversky & Kahneman's' survey of 1981 The Asian Disease Problem. A survey was conducted on the Internet (N = 200). An identical problem was added, yet with The Swine Flu as the disease. This was done to be able to investigate if there are any order effects, and also if it matters whether the mentioned disease is fictional or real. The results show the same results as Tversky & Kahneman already noted; positively and negatively framed problems generate different responses from the participants.

Uppdraget möter verkligheten : En essä om korstrycket på pedagoger

This essay is about the meeting of the pedagogic mission and the reality of the conditions in preschools. It is about the frustrations that I, as a pedagogue, experience when I cannot fulfill this mission. An example of this is working when understaffed.My purpose is the acknowledgment of two main areas of the curriculum: caring and learning. This essay demonstrates the diversity of the occupation and it ?s constant need of positioning.

Hållbarhetslivscykelanalys på kakel och klinker : Analys av vägen från vagga till grav ur ett hållbarhetsperspektiv

In this report two Sustainability Life Cycle Assessments are carried out for two types of tiles for Riksbyggen, to contribute to a sustainable urban transition. Sustainability Life Cycle Assessment involves performing a life cycle assessment based on four principles based on scientific research and presented by the non- governmental, non-profit organization, The Natural Step. The principles concern raw materials, chemically produced substances, degeneration of nature and social conditions.Origin of products, manufacturing sites and manufacturing procedures were initially completely unknown and much of the work has consisted of finding the entire cycles, understand manufacturing processes of ceramic tiles and evaluating what materials and what type of energy sources that are required for the production. A socially sustainable perspective has been of high relevance alongside an ecologically sustainable perspective.The report begins with the basic underlying facts and the purposes of this investigation and that the reasons why Sustainability Life Cycle Assessments are carried out are to provide Riksbyggen and the own workers with documents presenting Riksbyggens ideas regarding sustainability and to hopefully get the ideas further down in the supply chain. The methods used to fulfill the investigation are presented and scientific facts about LCA and ceramic building materials are reviewed.

Judendomens livsbejakande budskap : Framställs detta i den svenska gymnasieskolansreligionsläroböcker?

Detta är en uppsats som har fått sin utgångspunkt från rapporten ?Om sociala problem i nya bostadsområden? från Centralförbundet för socialt arbete. Rapporten från 1976 konstaterade att det i hög grad förekom sociala problem i de nya bostadsområden som byggts enligt Miljonprogramsmodellen. I Halmstad byggdes bostadsområdet Andersberg för att bota den bostadsbrist som under 1960-talet rådde i Halmstad. Då området byggdes enligt normer från just Miljonprogrammet, blev uppsatsens syfte att se hur väl detta bostadsområde stämde överrens med de definitioner av sociala problem som preciserades i rapporten, samt att ge en lokal och levande bild av det tidiga Anderberg.

Detektor på skördare för utsortering av träd med metallskrot

Fortifikationsverket which is the landlord for the Swedish national defence has a great problem in their forestry due to the relatively large amount of metal objects in their timber. These metal objects cause different types of economical losses in the timber refinement chain. To enable out sorting of logs containing metal objects already in the harvesting phase, Fortifikationsverket is interested of the possibility to utilize some type of metal detector in a harvesting head for that purpose.The goal of this study was to, with help of a case study, enlighten the problem that metal objects in timber cause for Fortifikationsverket and their customers of timber and to investigate conditions of to mount and utilize some kind of metal detector in a harvesting head at present.The saw timber deliveries by Fortifikationsverket during the time period 2003-2005 was used as a reference volume for calculations of economical losses. In this case study was included two sawmills where timber from Fortifikationsverket were delivered to for further refinement. Factors investigated were the type of damage metal objects caused in these two sawmills and the economical signification of these damages.

Ljusföroreningar i stadsmiljö : Hur kan ljusföroreningar förebyggas vid nybyggnation?

Light pollution in urban areas - How to prevent light pollution at construction Jakob Sjöling Light pollution is a relatively new but rapidly growing form of pollution. Society's increasing demand for light coupled with the pace at which lighting technology evolves is accelerating that growth. The purpose of this study was to analyse how the construction industry plan and design outdoor lighting when erecting new buildings, specifically with regards to the issue of light pollution. It also investigated how local authorities work with these issues during urban planning. In both cases special interest was placed in ways to improve the planning and use of outdoor lighting in order to minimize light pollution.

Uppdatering av metadata i ett Data Warehouse: ett organisatoriskt perspektiv

Data Warehouse är ett relativt nytt fenomen i jämförelse med traditionella databassystem, och i och med de senaste årens kraftiga tekniska utveckling har förutsättningar för att realisera konceptet skapats. Inom branschen finns ett antal problem rörande metadata, som i denna uppsats legat till grund för vår inriktning. Många av dessa problem beskrivs utifrån ett tekniskt perspektiv, vilket detta arbete inte gör. Vi har istället valt att undersöka vilka problem som föreligger vid säkerställning av att metadata hålls uppdaterat i ett Data Warehouse med hjälp av tydlig ansvarsfördelning. Vi har funnit att det föreligger vissa likheter mellan de problem som konceptet Knowledge Management angriper och de problem som en organisation ställs inför när man söker säkerställa att metadata hålls uppdaterat med hjälp av tydlig ansvarsfördelning.
