Fuktegenskaper hos Quartzene impregnerat med salter
Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.
COP15 - Jakten efter ett ambitiöst och globalt klimatavtal. -Vad motiverar Danmark att verka för ambitiösa bindande klimatmål?
Until recently the Danish government was hesitant about whether investments in climate and energy policies were the right strategy for Denmark. Today the Danish government argues that during the forthcoming climate conference in Copenhagen in 2009 (COP15), the world's countries must agree upon ambitious climate objectives. Denmark is together with EU-27 aiming at an ambitious climate agreement. This thesis intends to contribute with an understanding of why Denmark, both politically and economically, invests profound resources into committing the world's countries to a climate agreement. The study uses both a neoliberal institutionalism and a constructivist theory in analyzing the Danish engagement.
Kvicksilver i skogsmark
I mer än hälften av Sveriges sjöar innehåller gädda en kvicksilverhalt som övergår Food and Agriculture Organization?s (FAO) rekommendationer. Det kvicksilver som finns lagrat i svensk skogsmark är ett resultat av antropogent nedfall. Studier visar att kvicksilver utlakas vid skogsbruksåtgärder på hela skogsmarken som en följd av förhöjd rörlighet av dissolved organic carbon (DOC). En ökad metylering av kvicksilver sker vid vattenmättade, syrefattiga förhållanden där det finns tillgång till organiskt material.
Corporate Social Responsibility - Alla företag har ett klimatavtryck, det är bäst vi lägger oss ner och dör!
Sustainability work is something that is emphasized more and more. Corporate Social Responsibility, CSR, is discussed and the question of how much responsibility companies should really take is frequently in the news. Companies tend to ask themselves how much responsibility they should take. CSR is a common concept of companies environmental and social work and a concept we tend to see here and there in our modern society. CSR includes companies? social responsibilities, both in terms of carbon footprint, working conditions, social responsibility and more.
Svaveldosering av biopanna : En utvärdering av doseringen med svavelgranuler för att minska utsläpp av kolmonoxid från biopannan hos Arvika Fjärrvärme
Detta arbete utfördes i syfte att analysera och utvärdera effekterna av att dosera svavel till förbränningen i en biopanna. En utrustning för detta ändamål installerades till biopannan vid fjärrvärmeverket i Arvika för att få bukt med höga halter av kolmonoxid i rökgaserna. Analysen har genomförts med avseende på hur väl svaveldoseringen uppfyller sitt tilltänkta syfte men även på eventuella bieffekter. Korrosionsrisker, halter av oförbränt svavel i rökgaser, rökgaskondensat, flyg- och bottenaska samt vad som sker kemiskt i förbränningsprocessen vid tillsats av svavel har studerats. Driftrapporter från biopannan analyserades parallellt med en informationshämtning i form av en litteraturstudie och kontakt med sakkunniga personer för att svara på ställda frågor.

Visbys färger : exteriör färgsättning av bostadshus i Visby innerstad 1860?1930
The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).
Åkerinäringens inställning till biodiesel : en marknadsundersökning
In Sweden, there an increasing need for transport and this leads directly to fuel demand of the transport sector is expected to increase. Both politicians and industry believes that renewable fuels are a realistic and significant method to reduce the transport sector's environmental impact. This study aims to document the Swedish haulage contractor?s attitude to biodiesel. Also to document the strengths and weaknesses of biodiesel, based on opinions from the ultimate consumers.
Krafttag : sociala dimensioner i industrimiljöer med fokus på vattenkraftverk
Det här arbetet syftar till att återinföra frågorna om samhällelig nytta och estetik i debatten kring, och byggnadsprocesserna för vattenkraftverk. Det argumenterar att vår omgivning spelar roll både för vårt psykiska och fysiska välbefinnande och att genom att öppna upp verksamma industriområden till att bli en integrerad del av samhället kan en spännande ny plattform skapas där det finns plats för lärande och förståelse av industriella funktioner samtidigt som helt andra aktiviteter och funktioner också kan finnas. Från att vara en exkluderande plats med bara en funktion går industriområdet till att vara en välkomnande multifunktionell plats. Transparens och deltagande är ledord.
Sedan modernismen har industriella miljöer blivit allt mer åtskilda från de städer och samhällen som de ingår i eller gränsar till. Genom funktionsseparering har nya industriella områden tillåtits bilda introverta enklaver som gör sitt bästa för att hålla människor både fysiskt och visuellt uteslutna.
Påverkan från den förväntade klimatförändringen på tillväxten i norra Sveriges skogar : En litteraturanalys
This is a literature review of how the climate change affects the forest growth innorthern Sweden. The temperature will rise about 5 °C with the largest increase in thewinter season (December - February) and the CO2level in the atmosphere is expected tobe doubled. Precipitation patterns will change and increase with 25-35 % and theprecipitation will be in form of rain rather than snow. Today the forests in northernSweden are entirely dominated by coniferous stands. This may shift with the climatechange and results in a larger number of deciduous trees, preferably birch will becomestronger and grow better and faster.
Faktorer som påverkar magnesiumabsorptionen i våmmen hos kor
In metabolism Mg plays an important role because it affects many cellular enzymes in the body. The energy metabolism and protein synthesis are dependent on Mg as an enzyme activator, Mg is also involved in the synthesis of RNA and DNA. Absorption of Mg primarily takes place over the ruminal epithelium in ruminants. The main storage of Mg is in the bones but that can only be reached if the cow is in great need of calcium or phosphorus, it's a hormonal regulated process that induces catabolism of bones. Free and available sources of Mg are found in soft tissues and in the extra cellular fluids that includes cerebrospinal fluids and blood.
Hästtransportsläp - krav, utformning och funktion :
SUMMARY
The interest of horses in the riding sector has increased the last decades. A large amount
of horses are transported in a 1 or 2-horse trailer, which is pulled by a car. Today a large
number of different products and designs of trailers can be found on the market. The
difference in shaping of trailers depends on tradition and experience. There are no
detailed directions on the demands for shaping of horse trailers today.
The literature review contains a market analysis of both Swedish and imported horse
trailers.
Optimering av SNCR-system i en biobränsleeldad panna : möjligheter till minskade NOx-utsläpp för ENA Energi
Emission of nitrogen oxides as well as carbon monoxides is an inevitable result of combustion. A Swedish law "Law of environmental fee for emissions of nitrogen oxides as a result of energy production" (lagen om miljöavgift på utsläpp av kväveoxider vid energiproduktion (SFS 1990:613)) controls the emission of NOx from energy production by a system of fees. The system has resulted in a strong approach toward less emissions of NOx among the energy production plants. High emission levels, today exceeding 52 mg/MJsupplied fuel, leads to costs for energy production companies. This paper examines possibilities to reduce the emissions of NOx by optimization of the SNCR-technique in a biofuel fired heat and power plant.
Transit Objekt
Transit Objects In the Master Essay I argue around two existing levels in the works presented at the graduation exhibition. On the one hand, it is about influence; on the other hand it is about the phenotypes of purpose-ness. In the introduction, I describe the relationship between the shapes that I have come to call Transit objects, and their on the one hand ideological superstructure; on the other hand, the different aspects of their shapes regarding the imitation I, in creating the objects, performed. In the case with the objects shape-aspects, I stand on the thoughts that I found during my bachelor's work, that is, to express the phenotypes of purpose-ness.When it comes to influence, I speculate about how linguistics, and particularly a branch called neuro-linguistics, illustrates how the arguments that make up our world can be transformed. I use a meta-model and a conversation model as a tool to illustrate this. When I, like that, illustrate the plasticity of meaning, and cognition, I note Catherine Malabous taught (in her book What Should we do with our brain?) on the plasticity of the brain in relation to the neo-liberal systems of capitalism. She argues for how the brain has come to stand model for the organization of different types of networks. I hint the link to a future scenario where the desire to influence takes new forms and uses the latest brain research challenges, more specifically the use of ultrasound for the treatment of pain and other similar conditions. This also can be used as generating various types of seizures, pleasant or unpleasant.
Modellerade och uppmätta kväveflöden i energiskog som bevattnas med avloppsvatten
The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.
