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.

This thesis analyses the conditions for subject indexing of fiction by studying the relationship between the nature of fiction and the properties of subject indexing. The analysis is founded on a reading of a recently published Swedish subject headings list and uses a theoretical framework of Adornos theory of modern reason. The study is conducted through a qualitative text analysis in three steps. In the first step the subject headings list is analysed by examining how it provides subject access to fiction by the aspects of form, frame and subject. In the second step of the analysis these aspects of subject access are analysed and discussed by relating them to relevant research of subject indexing of fiction.

Identity includes an individual´s self-image and the consciousness about their self. It is about being the same person despite changes in their life situation. The identity often get´s fragile because of the disease. Beacuse of the individual´s feeling of lost identity there may arise a conflict between the person and people in his or her surroundings. They may no longer see the sick person in the same way as they used to.

Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..

Konsumtion kan vara allt från ditt köp av tuggummi, ett par nya skor, en gammal päls från 70-talet, en resa till Indien, till en kebabrulle nere på hörnet. Samtidigt innebär detta att du betalar för smaker, utseende, åsikter, upplevelser, känslor och kulturer. Detta är att leva i ett konsumtionssamhälle. Det du konsumerar speglar vem du är och hur du vill att andra ska uppfatta dig ? alltså din identitet.

By immersion in the situation of the food production today and a historical study of how past development has led us to this point, one goal of this essay is to discuss whether the current way of farming can be applied in a sustainable future. Another objective of the essay is to study the vision Vertical farming as an alternative approach, and to focus on different aspects of this phenomenon in order to provide as comprehensive a picture as possible.The paper, thus, seeks to broaden the views for alternative approaches regarding a well-established method which we often take for granted. The aim is also to initiate a discussion around the need to also take radical ideas in regard if we want to face the future in a sustainable manner. The method is a qualitative literary study where scientific articles and papers have been used to discuss the issues: why has the idea of Vertical farming arisen, what is Vertical farming and how is the Vertical Farm meant to operate? Does Vertical farming have a place in the sustainable city of the future? For a long time us humans lived as one with nature, in a symbiotic relationship in which we gave and took as a functioning part of an ecosystem.

Introduction     Knowledge has come to be an increasingly important factor for both individuals in the labor market and companies in competition. When a person leaves an organization the knowledge often follows, and a knowledge gap is created. When knowledge is shared within an organization, the individual?s knowledge is available for all members of the organization. Knowledge can thus be converted from human capital to structural capital.

The paper evaluates two housing proposals with Space syntax as method. The proposals are very different in a topological sense but are in a configural sense almost the same. This effect is because both proposals connect themselves to the existing configural structure of the city in the same way. Neither of them takes advantages of the most integrated streets in the existing structure and use them to concentrate pedestrian and car flows to the streets or points which are intended to be the most urban areas. The knowledge of Space syntax and this evaluation puts focus on the pour understanding among architects and planners of what effect urban design proposals will have..

This thesis is a study over changes and similarities of people's activities in Berzelii park, with focus on the second half of the 19th century and present time. As one of the oldest public parks in Stockholm, Berzelii park has been a place for outdoor activity for more than a hundred years. During that time both the park and the society have undergone changes, but people are still using this green area in the city centre in a similar way as generations before have done. It is still a place for social gathering and during the summer month the park invite for optional and social activities such as a pause in the sun and pic-nic with friends. Some customs has disappeared like the 19th century social stroll, but through small changes in rules or design others have become given, like using the lawns as seating..

Libraries exist around us and for most of us they are a part of our every day life. But how often do we stop and think about their meaning?Libraries in fiction are usually not the center of the narrative, they play a role quietly in the background and offer a backcloth to the story. Yet they are a vital part of the story. Without them a big part of the magic in the stories would be lost.And what is their role in our lives? What do the libraries mean to the books they harbor, the readers who seek them out and society in which they have their axiomatic role?This essay?s focus is my story ?Between the shelves?, which is about the young girl Julia and the mysterious passageway she discovers in her local library.

One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.

AbstractThe political parties in Sweden are losing members. This is seen as a problem because the political parties are the base and the recruiting ground for members to decision-making bodies. Social movements are seen as a place where people with a modest background could express their opinions and also learn the political process. These movements have also lost members during the last decades and this could seriously affect the representation of lower social groups among the decision-makers. This essay emanates from Robert D.

This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..
