Agriculture has to be performed in a sustainable way in order to sustain high yields and to support a globally growing population. Functional soil properties are fundamental for high yields and in order to achieve good soil conditions sustainable management is a key. Loss of soil organic material and increased soil acidity are problems associated with degradation of soils and hence less sustainable agriculture. In this thesis, the effect of different agricultural systems on soil organic matter, pH and yield was examined. The systems examined are a cereal system with straw removal or returning and a ley system, all with different nitrogen levels.

Platelets are important for the healing of damaged blood vessels since they have an importantpart to play in the coagulation process. At the same time, the blood must be kept fluid and notcoagulate at the wrong time. Therefore there are factors that effect the aggregation of plateletsin a positive or a negative way.Previous investigations have shown that platelets during stirring conditions produce reactiveoxygen species (ROS) that weaken the inhibiting effect of nitric oxides (NO) on platelets andthat the drug Dexamethasone (Dex) can reduce the ROS-production.The aim of this project was to investigate if glucocorticoids, in this case Dexamethasone,could restore the inhibiting effect of NO on platelets and if there was any decrease in ROS-production.The result of the ROS-measurements showed a great variance and it was difficult to draw anyconclusions from them, but a clear decrease in ROS, as previous reported, was not shown. In the aggregation experiments the inhibiting effect of NO was observed through the drug S-nitroso-N-acetylpenicillamine (SNAP), a NO-donator.From the aggregation experiments, the result seemed to be that SNAP during longerincubation time lost its inhibiting effect, probably because the cells become desensitized.With superoxid dismutase (SOD), the effect of SNAP increased, both in the experiment withlonger and shorter incubation times. Dex seemed to reinforce the aggregation in relation toboth SOD and SNAP.

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

ABSTRACTThis paper aims to shed light to what extent a financier have learnt about sustainableorganizational change, through development projects taking part in the Swedish knowledgeFoundations program, ICT in Teacher?s training. Some questions asked were: Has theSwedish Knowledge Foundation learnt by researchers? and self evaluation?s ?stirring up? ofongoing projects? What type of learning process has been going on? Has new, mutual,knowledge been constructed or has already existing knowledge been transferred?The study consists of one participating observation and three interviews. They showhow the financed projects have been ?stirred up? so that a developmental learning process hasstarted within their organization.

AbstractTitle: The first thing I do when I wake up is to log on to Facebook. A study regarding how users of Social Networks experiences the User Generated production. (Det första jag gör när jag vaknar är att logga in på Facebook. En studie om hur användare av de sociala nätverken upplever den användargenererande produktionen.)Number of pages: 37 (39 including enclosures) Author: Per MagnussonTutor: Christian ChristensenCourse: Media and Communication Studies CPeriod: Fall semester 2010University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The ambition with this essay is to examine how the online users of social networks experience the development of the Internet towards Web 2.0, and the enormous User Generated Content emerging from it. How do we receive User Generated Content from other people, and particularly what do we think about our own production.Material/Method: In order to obtain a deeper understanding of the attitudes and perceptions amongst people regarding this subject I used qualitative interviews with 9 people.

Hållbar utveckling i skolan? en studie om hur lärare arbetar med hållbar utvecklingSustainable development in school? a study about teachers work with sustainable developmentI detta arbete har jag tittat på hur lärare med inriktning mot naturvetenskapliga ämnen arbetar med hållbar utveckling i klassrummet. Jag har i teoriavsnittet valt att börja med en definition av begreppet hållbar utveckling där de tre olika perspektiven miljö, socialt och ekonomi tas upp. Sedan beskrivs det aktuella miljöproblemet global uppvärmning, för att sedan i teori delen ta upp vad som står om hållbar utveckling i läroplanen och i kursplanerna för kemi, biologi och fysik. I det sista teoriavsnittet beskrivs hur två olika skolor har arbetat på olika sätt med hållbar utveckling.Metoden som har använts i undersökningen är kvalitativa intervjuer där fyra naturvetenskapslärare har intervjuats om sin undervisning i hållbar utveckling.

The Swedish consumption of lamb a increasing, and today we yearly eat a kilo of lamb per person each year. As a consequence the Swedish degree of self production according to lamb is steadily decreasing, and is today about 39 %.Today Swedish Meats is now cooperating with the Swedish lamb breeders organisation to raise that percentage. At the same time the European Union presents a new agricultural reform, the MTR (Mid Term Review). The shape of this new reform is not yet fully known, but the general policy has been more or less outlined. The new reform is split into three propositions: the farm model, the regional model and the mixed model.

The focus of this essay is on a political party that was founded in Sweden in 1904. Today, we known it as Moderata Samlingspartiet. Historically, this party has transitioned through multiple phases which have included a change of name and also a change of substance in the area of trade policy. The party that was cheering globalisation at the 2006 congress had its roots in protectionism and had been founded as a strict protectionist organisation. The question raised here is what has caused this dramatic change in the trade politic?In addressing this important question, I have used both organization and party strategy theories to identify the main underlying reasons.

Traditionally, mining has been performed mechanically with implementation ofyesterdays (and older) data. Several mining companies have started to useautonomous technology and robotics in the production areas although the harshmining environments make it unsuitable for today's electronic equipment. Despite allthe obstacles along the way of digitization, there seems to be no end in sight as thisdevelopment continues. This thesis focuses on what the mining industry is aiming forand why the mining companies are interested in these technologies. The actors of themining industry can be found to have a vision for the future mine, a production with ahigher degree of digitization and resemblances to a factory.

Fossil fuels are affecting our climate negatively and there is a limited amount of them in the world, which leads to the importance of finding alternative fuels. One alternative is biogas, which is produced though a digestion process of different organic materials in a biogasreactor. Organic substrate that comes from farms has the biggest potential to increase the production of biogas in Sweden. Primarily crops from farms, but also waste products like manure are of great importance.Today there is a calculated theoretical potential for biogasproduction of 14TWh per year, which is around ten times larger than Sweden?s production today.

Denna rapport innehåller en redogörelse för mitt examensarbete, Charlie åkerkarusell, som gjordes vid Carl Malmsten ? Furniture Studies, LinköpingsUniversitet, våren 2012. I mitt arbete undersöker jag hur man kan serietillverkaen liten produkt med hjälp av mallar och fixturer anpassade för film och hur mandokumenterar processen med hjälp av film. Jag har tittat på olika filmer som rörämnet och olika typer av mallar för att sedan formge en liten figur vid namnCharlie, som serietillverkades i en serie av 30 stycken. Jag utförde några avmomenten i serietillverkningen med hjälp av en typ mall som jag konstruerade.Mallen, som jag valt att kalla för karusellmall, är inte den mest rationella men ärdäremot betydligt mer spännande och spektakulär än en traditionell mall.
