Realisering av en modulär skogsmaskin - En skalmodell
Wood for commercial use is harvested from forests using forest machines like harvesters which folds, branches and cuts trees and forwarders which transports logs to a landing area for further transport to a processing facility. Future forest machines have to be much gentler to the machine operators and forest soil than today's machines. Hence new machine solutions must be developed and tested. A practical way is to develop a physical scale model which can be used as a test-bed to incorporate different types of solutions for suspensions, cabin damping, tires and tracks, crane and overall architecture. The aim of this project was to develop such a 1:5 scale model of a forest machine, named as ?Skogbil.A scaling strategy was employed to arrive at important scale dimensions and specifications ofSkogbil which would be comparable to the full scale model.
En diktaturs väg in i Informationssamhället Kina och World Summit on the Information Society
This masters thesis investigates the relation between China and the Information Society as it is manifested in the UN conference the World Summit on the Information Society WSIS. The first phase of this two-phase conference took place in Geneva 10-12 December 2003, with two documents, Declaration of principles DP and Plan of action PA, as main results. The information policy is central to an authoritarian rule in its efforts to keep control over the national identity. The thesis investigates the impact that the information revolution and Internet might have on the Chinese national identity through the acceptance of DP and PA in various aspects. With the use of the information science theories by Manuel Castells and Frank Webster, the vision of WSIS was compared with the Chinese information policy.
Vattenkemin i Fyrisån under snösmältningen
Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.
Arbetsgivarens utökade medfinansiering och rehabiliteringsansvar
Sjukfrånvaron har ökat sedan 1980-talet. Regeringen har åtskilliga gånger försökt utreda hur de bäst ska kunna sänka sjukfrånvaron och öka arbetsgivarnas delaktighet i problemet. Den senaste åtgärd regeringen genomfört är införandet av lagen (2004:1237) om särskild sjukförsäkringsavgift och ändringar i lagen (1962:381) om allmän försäkring och lagen (1991:1047) om sjuklön. Införandet har medfört att arbetsgivaren har ett utökat medfinansieringsansvar och därmed ett större rehabiliteringsansvar. Uppsatsens syfte är att studera om regeringens intentioner har fått önskad effekt på de arbetsgivare vi intervjuat.

Årlig gödsling med NPK bäst för gröda, miljö och ekonomi
Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.
Risk för exponering av växtskyddsmedel i växthusmiljö
Plant Protection Products (PPP) used in the horticulture industry can be both chemical and biological. They are used for weeds (herbicides), insects (insecticides), and fungi (fungicides) and as growth retarders.Many horticulture workers get in touch with plants, treated with PPPs and many of these don?t use any protective equipment.The aim of this project is to illustrate the work environment hazards for staff working with greenhouse pot plants, after they have been sprayed.The method used was observations of the operations for packing plants. I studied the operations and took notes of how operations were performed and what protective equipment they used. I also took photos and asked questions.A literature study completed the observations.
Det för(s)könade biblioteket En diskursteoretisk läsning av biblioteket vid KVINFO
This thesis applies a discourse theoretical approach in order to examine in whatways and with what possible meanings the library at KVINFO participates in the overall gender discourse in society. This means that our reading takes place at a metatheoretical level, focussing on the library as a constructor of meaning in relation to society's gender discourse.Besides the actual reading, the thesis argues for the fruitfulness of using both a discourse theoretical and a feministic perspective in the field of Library and Information Science. By looking at libraries in general through a lens provided by these perspectives, libraries are staged as battlegrounds for competing discourses,that attempt to promote its particular knowledge claim on how reality should be perceived.The reading shows that it is possible to perceive the library at KVINFO as amaterial articulation that takes shape by and is part in a feministic counterdiscourse against the masculinistic hegemonic discourse, which throughout ?hisstory? has positioned women as ?the other?, and established men as the normative category in society, including the libraries. Through its practise KVINFO has contributed to a change in the collective identity ascribed to women.
Berättande i datorbaserade rollspel - en empirisk och teoretisk designstudie om datorspel
VD:n för spelindustrins intresseorganisation (Interactive Digital Software
Association) förutspår i den årliga State of the Industry rapporten för åren
2000 ? 2001, att spelindustrin snart kan nå 70 procent av världens hushåll,
vilket gör spelmaskinen, näst intill, lika vanlig som videon.
I denna dag börjar många spelutbildningar växa fram i hela landet, så som i
Karlshamn, Visby och Kramfors. Trots denna tillväxt finns det nästan ingen
akademisk forskning i ämnet speldesign. Detta gör att hjulet i många fall
tvingas återuppfinnas om och om igen.
I detta kandidatarbete är huvuddiskussionen hur man designar ett spel
innehållande både spelfrihet och en färdig berättelse, vilket är en konflikt i
sig. Vi försöker identifiera kärnan av ett spels design genom att samarbeta
med både användare och designers av digital underhållning och sätta detta i
relation till de studier av spel vi gjort.
Inverkan av SPC på induktion av protein AF och produktionsresultat hos slaktkyckling
This study was a degree in Master of Science in agriculture with specialization in animal science for the Department of animal nutrition and management at SLU. The subject was created by AS-Faktor, a small company for science and development within the company Lantmännen AB. It was a test of the effect of SPC (Special Processed Cereals) on induction of the endogenous protein AF (an antisecretory factor) in plasma and intestinal lumen in broilers. Previous results have shown positive effects on different intestinal diseases in pigs, horses, dogs as well as in humans. Beside the induction we also studied the effects on results in a conventional slaughter chicken production, including the ability of SPC to compete with or be affected by the coccidiostat, Salinomax.When diarrhoea occurs, it's because there is an imbalance between the secretion and the absorption and it can be caused by for example toxins.
Arbetsgivares primära förhandlingsskyldighet enligt 11 § medbestämmandelagen
The employer is obligated to call for negotiation on his own initiative, before he makes decisions in questions, which constitute important changes of the employer?s business or of the worker?s working conditions and terms of employment. The obligation to negotiate is reserved to the organisations, which the employer has collective agreements with. But what does the concept of important changes mean? What areas are included in the concept of important changes, according to legal framework and case law? How extensive is in fact the employer?s obligation to negotiate? The purpose of this report has been to seek answers to the above-mentioned questions, through partly describing how the employer?s obligation to negotiate has developed, and partly describing how the codes of negotiations in the Employment (Co-Determination in the Workplace) Act of 1976 are raised and applied.

Allt utom byn Sökandet efter en vikingatida by i sydöstra Blekinge, med områdena runt Järrestad på Österlen och Sorte Muld på Bornholm som jämförelsematerial.
The purpose of this essay is to see if villages or bigger settlement locations can be found in south-eastern Blekinge during the viking age. There have been many archaeological findings from this period in Blekinge, for example grave findings, ring-forts , old roads and ancient harbors. But no evidence of a village has been found yet. If south-eastern Blekinge is compared with the area surrounding Järrestad on Österlen in south-eastern Skåne and the area surrounding Sorte Muld on Bornholm, many likenesses can be seen. In this essay, the findings in Blekinge will be used as different components when the three areas are compared with each other.
Platsrelaterat själv och autobiografiska minnnen hos svenskar boende i Schweiz
The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.
Vinterförvaring av Pelargonium x hortorum :
There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?.
The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to.
Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.
