Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
"Så nära men ändå så långt borta" : ? en studie om hållbar destinationsutveckling på Sandhamn
Sustainable destination development has in recent years become an increasingly important concept for tourism destinations. A destination must take into account the environment if it wants to continue being a successful tourism destination in the future. This essay investigates what needs to be developed on theislandofSandhamnfor that the destination can be more attractive in the off season and how the players on Sandhamn integrate to develop Sandhamn in a sustainable manner. One market research and interviews with five different players were made. Through these interviews grew an understanding for how the cooperation between the municipal and the private party looks like and how the history of Sandhamn is the foundation for the islands tourism development.
Vattensork och åkersork - skadegörare i svensk fruktodling
There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.
Subjektiv och objektiv bedömning av underlag på svenska hopptävlingar på elit- och nationell nivå
Bark-stripping by red deer (Cervus elaphus) cause extensive damage to economically valuable spruce trees (Picea abies) in Swedish forests. The underlying causes for bark-stripping are not fully understood, and the frequency and severity of damage unpredictably differ between regions. In this study, I investigated if landscape structure (e.g. agricultural dominated landscape opposed to forest dominated landscape), forage availability, population density and disturbance (e.g. roads and settlements) affect bark-stripping frequency.
Förekomst av törskate (Cronartium flaccidum, Peridermium pini) på tall (Pinus sylvestris) i relation till markfuktighet och fältskikt : en studie om 2000-talets törskateepidemi i norra Sverige
Resin-top disease is a rust fungi that occurs both as a host alternating form, Cronartium flaccidum G. Winter., and as a non-host alternating form, Peridermium pini Pers. The host alternating form can use a variety of hosts but the most commonly used species in the boreal forest is Melampyrum sylvaticum. In Scandinavia the Resin-top disease infect Scots pine, Pinus sylvestris L. The fungus infects the needles through the stomata and then grows through the branch to the stem where it strangulates the vessels transporting water and nutrition to the treetop, which kills the top.
Övergödning av Mälaren : Betydelsen av antalet beviljade dispenser av stallgödselspridning vid Sagån
Eutrophication was recognized in the early 1900's and results in severe algal blooms, increased biomass production and eventually leads to an altered ecosystem. In Mälardalen we find the most eutrophic lakes. Most of the applied phosphorus and nitrogen into seas and oceans comes from agriculture, and the nutrients losses are affected by local weather conditions and soil type. Guidelines for storage and distribution of manure were introduced in the 80s, and the rules were strengthened January 1, 2010. Localities and previous county administrations can whether there are special reasons, grant an exemption for manure application during winter-periods despite the current ban.In this essay I have examined how many exemptions of manure application that has been granted at the Sagån river, and what implications it has for the eutrophication of Lake Mälaren.
Optimering av reducerad bearbetning : högre skörd till lägre kostnad
Optimization of soil tillage and crop rotation is important in many aspects, but particularly in maximizing profit margins. Since the economic outcome is usually decisive, it can be interesting to study different combinations of soil tillage systems and crop rotations in order to identify the maximum economic outcome. How a crop functions in a particular tillage system determines whether it is profitable to grow that crop. Different tillage systems affect the soil and its processes in different ways. Reduced tillage often works best on weak-structured heavy clays and on silty clays.

Titel: Human being and Christian ? creationtheology of Gustaf Wingren.Analysis of an accentshift from a juridical theological metaphor to a biological theological metaphor.Author: Tove Pilroth.The purpose of the essay is to analyse the meaning and the consequences, in a critical and constructive way, of an accentshift of interpretation and understanding of the gospel, from a juridical theological metaphor to a biological theological metaphor. The purpose is presented in the frame of the creationtheology of Wingren. To be able to make the research and to answer the purpose of the essay, the following questions are essential:The human being is captive and redemption is liberation. If we are serious about that the gospel gives the human being rehabilitation, satisfaction, liberation and a life and a future with God, the essential question is which metaphor, a juridical or a biological, that speaks to the human being in the best way? What is the meaning of an accentshift from a juridical to a biological metaphor? How does the creationtheologhy of Wingren, from a biological metaphor, meets the situation of the existence for the human being, her longing for life, health and meaning? What kind of theological resources are present in the creationtheology of Wingren, in the confrontation with future theological challenges?The essay is stressing the need of pluralism in the interpretation of the gospel.
Upptag av bly, kadmium, tallium, torium och uran i vete, råg, sallat och potatis - resultat från en litteraturstudie och ett dosförsök
Denna studie behandlar upptaget av de hälsovådliga metallerna bly, kadmium, tallium, torium och uran i några viktiga grödor som vete, råg, potatis och sallat som används för humankonsumtion. Syftet var att studera faktorer och mekanismer som kan påverka grödornas upptag av dessa metaller. Målsättningen var även att utröna hur stor påverkan dessa faktorer har på grödornas upptag av Pb, Cd, Tl, Th och U.En litteraturstudie visade att de domesticerade grödorna vete, potatis, råg och sallat tar upp Pb, Cd, Tl, Th och U. Upptaget är störst hos sallat och potatis, förhöjda koncentrationer i åkermarken medför därför en ökad risk för att hälsovådliga koncentrationer återfinns i grödan. En ökad metallkoncentration av dessa grundämnen i marklösning och odlingssubstrat ger oftast högre metallkoncentrationer i aktuell gröda.
Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys
The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district.
The aim of this master thesis was to present an economic analysis of Norway spruce versus
birch.
Tidningen Dagens Nyheters uppfattning om vildsvinen (Sus scrofa)? : en innehållsanalys av en rikstäckande nyhetstidning
Since the wild boars (Sus scrofa) escaped from their enclosures in the 1970s, their numbers has increased dramatically. It is an animal that is currently involved in many traffic accidents. The wild boar is a popular animal to hunt. As the population has grown so has the hunting. But, unfortunately, there have also been an increased numbers of attacks on hunters.
Att ta vara på solens fulla uppvärmningskapacitet
The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.
