Motiverad för riskmedvetenhet? En studie om stadsarkitekterna i Dalarnas läns medvetenhet om, motivation för och arbete med risker vid fysisk planering.

The purpose of this study is to examine how risk is perceived by the urban architect's in the region Dalarna, as well as how this is reflected in their everyday work with risk and decision- making according to urban planning. The ambition is also to show how their risk awareness could be improved. The study is written in cooperation with Länsstyrelsen Dalarna as a part of their regional long-term goal to improve the region's proactive risk' and crisis management. The study is based upon 12 semi-structured interviews with local urban architects conducted during the summer and autumn 2007. The result shows that some architects are motivated for working with risk and think that risk awareness should be integrated in their everyday work, while others are not motivated and think that risk is more of a passing trend.

Diagnostiksystem i gaffeltruckar

This is a final thesis done at BT, considering one of their forklift truck models called Reflex. The first part of this report is about a preliminary investigation investigating what kind of diagnostic systems BTwants to use, and also which demands there are to meet all expectations on such system. Secondly a diagnostic system, which will show if the drive wheel is worn out, will be presented. In the preliminary investigation, two kinds of diagnostic systems were mentioned. These were Model based diagnosis and Predictive analysis.

Andlig växtodling, historiesyn och kunskapsteori - hur hänger dessa begrepp ihop? : en översikt av fyra odlingspraktikers ideologier.

Abstract Spiritual gardening, historical perspective and epistemology, - how do these concepts connect? A review of the ideologies of four pragmatic growers. The purpose of this thesis is: ? to present an alternative forthcoming perspective on knowledge, that may be of significance for future theories and knowledge about growing and gardening. ? to lift experiences with Nature Spirits into an academic context, that permits us a closer look at the phenomenon. ? to contribute to an academic platform connecting humanistic and natural sciences. The intention of this text is to bridge the differences between the strictly rational traditions of knowledge and those more experience based ones. The thesis wants to show that much can be won if feeling based and mental reflections once again are approached as equal sources of knowledge. The aim is to give an orientation about the subject of Nature Spirits. The interesting fact is not whether (that) one can talk to nature, but how one does it and that more can be understood about nature and the reality that the established sciences study. The form for this study of literature is a describing presentation; to put names on and give wording to the phenomena of Nature Spirits and Plantdevas. The sources of literature are four pragmatic practitioners of spiritual gardening who have written extensively about their own work.

Acceptansgränsen för solceller i lågspänningsnät : Kan den ökas?

Microproduction, also called distributed generation, is something that has become more and more popular in the electric grid. Microproduction can however lead to unacceptable performance if several units are installed in the same low voltage network. It is therefore good to know a limit where the performance of the low voltage network becomes unacceptable based on given parameters. This limit is usually called hosting capacity.In this report the hosting capacity with respect to voltage and current have been studied in three low voltage networks which are located in Falu Elnäts concession area. This has been done by simulations in a GIS-program where critical times of the grid have been simulated.

Kan svarta män älska vita kvinnor?

AbstractRelationships between white women and black men have become a topic of interest in various discussion forums. By examining different arguments within certain discourses, it becomes clear that discourses that have a distinct autocrat outline, i.e. a closed and declaring nature which excludes alternative discursive arguments, also define these relationships as different and deviant in comparison to relationships that does not encompass and include the constellation white women and black men. As a result of the use of autocrat discourses the white women and black men who enter into relationships are displaced and positioned as subaltern. A position which, on the one hand, allows for uninhibited criticism, but, on the other hand, and most importantly, it is a position from where they can be defined by others.

Gotland och Montenegro - att söka Bysans i den västerländska kulturen : en undersökning av Manastir Mora?asoch Mästerby kyrkas muralmålningar

In this essay the author has chosen to analyze the similarities and differences between some of the northern Europe?s late Mesolithic and Neolithic cultures. The research is of a processual standpoint and the information is mainly gathered from secondary sources as well as ethnological studies. The material collected has been analyzed in both a processual and a post-processual manner to most accurately study the foundations of the three primary theories describing the Pitted Ware Culture?s origin.

Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material

Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

Mjölkureahalten som mått på vom-mikrobernas kväveförsörjning och kons miljöbelastning

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

Samverkan mellan bibliotekarie och lärare kring elever med dyslexi : En intervjustudie av fyra bibliotekariers erfarenheter kring elever med dyslexi och samverkan med lärare kring dyslektiska elever  

This research focus on key groups; students with dyslexia, librarians and teachers, and interaction between these two professional groups regarding students with dyslexia. In searching for the exchange of knowledge and experience to meet dyslexic students needs, I have in this study turned the attention to librarians and their experiences with students with dyslexia.The purpose of the research has been through semi-structured qualitative interviews with four librarians, to explore and describe how they experience their work, in working with pupils with severe reading and writing problems, dyslexia, and interaction with teachers on this user group. The qualitative approach in the gathering of the empirical evidence is based on a desire to have an indepth and thoroughly understanding of the librarians experience.All informants in this study indicate that they see it as a natural part of their duty to keep themselves updated about dyslexia and what materials to suit the dyslexic user group. The informants have knowledge of dyslexia and have great knowledge and keep abreast on the latest technology of compensatory aids - alternative tools.The informants have primary a consulting and supply function for teachers and dyslexic students, where they are consulted on  suitable material in both fiction and facts in various disciplines. The informants highlights the importance of planning and preparation time to find suitable material, as audio books or easy read, so students who have a need for this also can be provided.

Ser det inte lite lika ut? : En kvalitativ studie av den icke stylade bildens potential att inspirera individen

Purpose: The purpose of this study is to investigate the effect and potential of a non-styled home reportage, and how they influence and inspire to promote individual creativity.Method: I have used a qualitative analysis to be able to create a deep understanding. This is based on three interviews with women in age 22-27, which have a dedicated interest in interior design. I have also sent questionnaires to two persons who run interior design blogs.Conclusions: My analysis shows that the non-styled home reportage is the start of an inspirational process that is beyond consumption and status objects. It promotes individual creativity and willingness to create, based on personnel taste. The essay highlights the importance that the individual critically examines the aesthetics of interior design as presented in diverse media.

Barns upplevelser av högläsning och boksamtal

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.

Corporate Social Responsibility, vara eller inte vara ? En undersökning om CSR förekommer hos svenska modeföretag och modekonsumenter.

The main purpose is to illuminate how a company links certain values to its brand in an effort to achieve a competitive position. We have done this by studying the government owned company Svenska Spel and its entrance on the netpokermarket. With Corporate Social Responsibility as a guidance for the company they wanted to offer Swedish gamblers an alternative to the, often morally dubious, international actors. Our thesis has taken an internal (corporate) as well as an external (consumer) perspective on the result of this strive. Our conclusions are that although Svenska Spel is successfully integrating social responsibility into their netpokerbusiness, they are facing a difficulty in making the consumer fully appreciate it.

S:t Göransområdet : gestaltningsprogram för ett stadsutvecklingsområde på nordvästra Kungsholmen i Stockholm

North Western Kungsholmen in Stockholm is confronting big changes and Stockholmsstad is planning that the area will be an extended part of the existing structure in centralStockholm. Dwellings and offi ces are built and the population increase heavily. Th isresult in a need to look at how public green areas can develop and be designed. Th epurpose is to design a proposal for a master plan of S:t Göranområdets public greenareas. Exploateringskontoret, Stockholm stad, who has initialized the task, claim thatthere is a need of clarifying and shield the qualities in the green areas of today and howto create new green structure.The problem formulations which are current in this master thesis are:? Is there a need of a distinct identity for the green areas of S:t Göransområdet? If so,how is this created?? How can the green parks and nature areas inside S:t Göransområdet be improved anddevelop?? How can the connections between the green areas inside S:t Göransområdet beclarifi ed and how can they connect to the surroundings?To get inspiration and information for the design this thesis include a study of theincluding parts in the design process.
