Environmental variables determining the occurrence of Cladonia parasitica and Hertelidea botryosa, two boreal lichens confined to wood

Biodiversity is essential for human well-being and it is defined as the genetic variation within species and the variety of species and ecosystems. Biodiversity provides several ecosystem services which are necessary for human beings but there are different threats towards the biodiversity. The biodiversity linked to the forest in Sweden are threatened, about 50 % of the red-listed species in Sweden are associated with forests. This is linked to the commercial exploitation of the boreal forest in Sweden which started 200 years ago. The forestry the last 50 years, with clear-cuts, have contributed to a fragmented forest landscape.

Ett vattendrags väg genom tid och landskap : Höje å

Water is a vital element and also enriches the experience of landscapes. It is naturally in constant movement and change but also exposed to the hands of man. In this paper two stretches of water is described through landscape and time in correlation between development and the experience of the watercourse Höje-å in the rural parts of southern Sweden. The intention is to investigate how Höje-å has changed over time and also how it is experienced in the surrounding landscape. With the help of literary studies the history of Höje-å have been described and through the course of field-studies the experience of two different areas along the watercourse.The biggest changes of Höje-å and its surrounding area have taken part during the last two centuries.

Att lämna en kriminell livsstil : En studie om ungdomars motivation och friskfaktorer efter en dom om institutionsplacering eller samhällstjänst

ÖREBRO UNIVERSITYDepartment of Behavioural, Social and Legal SciencesC-essay in Social work, Advanced course2006To give up a criminal life styleA study of motivation and protectional factors of juveniles after a sentence of institutional care or community workEmma Henriksson & Karin TengnäsABSTRACTThe purpose of the study was to investigate the factors that juveniles sentenced to institutional care or community work perceive as important for their decision to give up a criminal life style. The study approach was based on a few specific questions: (1) What aspects of the treatment have contributed to a motivation to abandon the criminal life style? (2) What have motivated the juveniles to make a decision to leave the criminal life style? (3) Are there any specific internal or external protectional factors that have been decisive for the rehabilitation process and, if so, are they linked to intrinsic or extrinsic motivation? The study rests on the theoretical foundation created by earlier research on institutional care, motivation and protectional factors. Interviews were chosen as a method to secure qualitative data and the interview manual was designed on the basis of themes that reflect the questions of the study. Six young people?s perception of their treatment is documented in the study, as well as their opinion on the effectiveness of the treatment.

Marknadsföringsstrategier för spelutvecklingsteam under utbildning

Syftet med denna slutreflektion är att visa problemen men även möjligheterna i marknadsföringen av spelet Forced2Fight av det lilla teamet i Kick the Owl Productions. Begränsad budget, osäker framtid för både team och spel är något som måste övervinnas. För att kunna angripa dessa problem har jag studerat en rad olika tillvägagångssätt och kommit fram till ett lämpligt tillvägagångssätt riktat åt gräsrötterna för att bygga upp varumärket. Den effektivaste strategin bör i min mening vara att marknadsföra gruppen via traditionella medier och förankra spelet i den relevanta målgruppen direkt via fora och andra sociala medier. Kontakta både framträdande medlemmar i sociala grupper samt expertgrupper bestående av kunniga spelentuseaster.

Inverkan av ensilagets partikelstorlek på beteende och beteendestörningar hos mjölkraskvigor :

Modern milk production have come a long way when it comes to accommodating the nutritional and physiological needs of the animals, but unfortunately the behavioural and psychological needs of cows and heifers are often left unfulfilled. A long time for eating is beneficial for the digestion and also gives the cattle something to do and decreases the risks for developing abnormal behaviours. An important factor that influences eating- and ruminating time is the particle size of the roughage. The aim of the study was to find out if particle size influences the behaviour of dairy heifers, in particular with regard to eating behaviour and abnormal behaviours. The study was conducted at Uddetorp farm high school in Skara. Forty-two heifers of the breeds SR and SF were housed in 8 slatted floor pens.

Numerisk simulering av jordtryck mot rörbro ? Med tillämpning av programmet PLAXIS

This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.

Human-cattle interactions and attitudes within dairy farming in Sweden and The Netherlands

Human-animal interaction is suggested to be a main feature within livestock production. The quality of handling, for instance, appears to be greatly depending on the attitudes and behaviour of the stock people. Various studies have been conducted on relationships between human and animals, but few have looked upon differences in human-animal interaction and attitudes between countries. Two countries often discussed in livestock production are The Netherlands and Sweden. It would be of interest to compare these two countries to find out whether (assumed) differences are reflected in the attitudes between animal handlers.

Restriktioner av växthusgasemissioner : hur påverkas lantbruksföretagens ekonomi och produktionsinriktning?

The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.

Optimalt råvarulager för biobränsleföretaget :

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

Strömmar av vatten och politik - en studie om policyprocesser och anpassning.

One of the distinguishing features of successful societies is the ability to adapt to change, bothsocial but also natural changes like climate change. Climate change is a complex, dynamic,non-linear process with a great deal of uncertainty concerning the time perspective, risks andconsequences. A combination of factors like climate change, geographical vulnerability, adensely populated and highly built up coast line along with factors like deficient handling ofsurface runoff and a large usage of ground water leads to an increasingly vulnerable society. Italso puts a greater pressure on the society to have preventive measures in place.The number of actors working with preparing society to the expected impacts of climatechange and variability is increasing. However more than half of Sweden?s municipalities donot consider changing climatic conditions when planning, and many times even allow theconstruction of new living areas in known climatically vulnerable areas.

Gårdsbaserade system för spannmålshantering i den framtida Lantmännenorganisationen :

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

Plantors och träds tillväxt efter schackrutehuggning och i konventionellt trakthyggesbruk

Eftersom hållbart skogsbruk innebär att man i skogsbruket tar lika stor hänsyn till de ekologiska och sociala aspekterna som de ekonomiska är det viktigt att utvärdera alternativ till det konventionella trakthyggesbruket för att säkerställa att alla värden i skogen uppnås. Ett så kallat schackrutesystem, eller Chequered-Gap-Shelterwood-System (CGS-system), är ett system där träd avverkas i mindre luckor som sedan alterneras med motsvarande skärmställningar. Detta skapar ett tvåskiktat bestånd med schackrutemönster. CGS-systemet är ett skötselförslag där fördelarna från både trakthyggesbruk och kalhyggesfritt skogsbruk eventuellt skulle kunna kombineras. Målet med denna studie är att utvärdera tillväxten av plantor och träd i CGS-system.

Hinder för svenskt trä inom den italienskabyggbranschen i allmänhet och produktsegmentenfönster och dörrar i synnerhet :

Italy is the third largest market in Europe with a population of almost 58 million. The country is the tenth most important market for Swedish sales. Italy has a fairly good economy at the moment and the forecast tells of an increasing strength during coming years. Despite all of this, Sweden is exporting a fairly small amount of wood to Italy. Only around 2,3 % of all Sweden?s wood export goes to Italy.

Metangasutsläpp från deponier och osäkerheter i beräkningsmodeller kring detta

I Sverige finns uppskattningsvis mellan 4000 och 8000 stycken deponier. De flesta av deponierna är nedlagda och år 2001 fanns det 142 stycken aktiva deponier för hushållsavfall. År 2010 hade antalet minskat till 76 stycken.  Vid nedbrytning av organiskt material i deponier bildas metanhaltig deponigas som bidrar till växthuseffekten. Utsläppens omfattning prognostiseras med hjälp av beräkningsmodeller, exempelvis IPCCs. Dessa modeller fordrar att antaganden görs av exempelvis andelen gas som utvinns via gasuppsamlingsutrustningen, det organiska materialets halveringstid och avfallets sammansättning och mängd.

Ett studium av olika aspekter av tid i Göran Tunströms roman Juloratoriet
