Kunskapens konstellationer: om ämnesanalys och tvärvetenskaplighet

The aim of this study has been to discuss ideas of knowledge within classification theory and subject analysis in the light of theories of fundamental changes in the production of scientific knowledge. Guiding questions have been: How have the conditions of knowledge production changed? How has interdisciplinarity as part of this development evolved? What assumptions lie behind theories of classification and subject analysis? How do these stand in relation to the alleged changes in the production and understanding of science? Three works about the changing conditions for knowledge production and the growth of crossdisciplinarity have been presented and discussed. These works stress the loosening up of boundaries between traditional knowledge domains and open up for discussions about how to organize knowledge production in the light of these changes. In the study it is argued that their works also could open up for discussions about the way knowledge is organized for retrieval purposes.

Svenskars benägenhet att ha en utrikes född partner : En kvantitativ studie om hur unga svenskars utbildning och bostadsort påverkar benägenheten att ha en utrikes född partner

Uppsatsens syfte ämnar undersöka svenskars benägenhet att välja en utrikes född partner utifrån individers bostadsort samt deras egen och föräldrars utbildning. Valet av partner analyseras utifrån ett perspektiv där valet inte sker slumpmässigt utan styrs av faktorer som påverkar möjligheterna till vilken partner svenskar träffar. Tidigare forskning har främst studerat parförhållanden mellan olika minoritetsgrupper och minoriteters tendens att ha en inrikes född partner. Eftersom parförhållanden mellan majoriteten och minoriteterna anses vara en indikator på hur starka gränserna är mellan olika grupper i samhället, är det av sociologiskt intresse att också studera hur majoritetsgruppen väljer en partner från minoritetsgrupper. Teoriavsnittet beskriver inledningsvis begreppen endogami, homogami och exogami som olika former av parförhållanden för att sedan diskutera hur svenskars partnermarknad påverkas av deras socioekonomiska resurser och sociala kontext.

Integrerad hästanläggning : ridhus/stall

Today there is an increasing market for businesses concerning horses, and since we are already running such establishments we sort of speak already have a finger in the pie. Due tothe increasing competition and demands, new and more practical constructions have become a necessity. In doing this project I wanted to make a comparison between having a stable integrated with a manege and having both constructions kept separate. I wanted to compare different layout and make an estimate of costs to see which solution would be less expensive and better with regard to working environment. I will further also deal with different ventilation-systems andlight transmissions.

Kartläggning av Kassationerpå Bubs Godis

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.

Studie i exteriör belysning : med tillämpning på Bokenäs, Volvos fritids- och konferensby

When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important. In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment. After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs. Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.

Lysande belysning? En komparativ sutdie mellan belysningsmöjligheter och rekommendationer

One part of preventive conservation is controlling the lighting in the exhibitions. As a first step we have to accept the fact that the very act of displaying objects is causing them damage, and because the trend is for everything to be open to the public view all the time, the aim is to minimize light exposure of exhibits.This essay will present lighting options and relate them to the current recommendations. I have put the emphasis upon describing which methods one can use to minimize the degradation of exhibits on display by eliminating UV- and IR-radiation and reducing the visible light. The intention with this essay is to investigate the current lighting options and compare these to the recommendations on lighting exhibitions.The selections of different lighting options such as LED-, halogen- and energysaving lamps were made based on avaibility. Thereafter I did two types of investigations.

Mätning av träddelar och flis på Dåvamyran, Umeå energi :

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

En ?terinventering och analys av den svenska populationen av svart nervmossa (Campylopus atrovirens)

Bristly swan-neck moss (Campylopus atrovirens) is in Sweden a very rare moss that only grows on a few blocks and cliffs around Gothenburg. The species can globally only be found in areas with high precipitation. Rain fall in Gothenburg has increased with a stronger greenhouse effect. Air pollution in Gothenburg has also improved. Mosses generally benefit from these conditions and this papers hypothesis is that the population of the species has grown because of these more beneficial conditions.

Vaktelproduktion för ägg och kött

The aim of this study is to review the commercial quail production for eggs and meat in the world. Another aim is to review the potential for increased production. Globally the quail production is very small, except in China where it is the second largest poultry industry. The production globally is small despite the quail's rapid growth, early sexual maturity and its high feed efficiency. The quail is also used as a laboratory animal and can be reared to be released in hunting areas.

Utvärdering av ett Bränslecellsdrivet Flygplan.

 With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.

Radiella vikter i Rn och lokala dimensioner

Kapaciteter kan vara till stor nytta, bland annat då partiella differentialekvationer ska lösas. Kapaciteter är dock i många fall väldigt svåra att beräkna exakt, speciellt i viktade rum. Vad som istället kan göras är att försöka uppskatta kapaciteterna, vilket för ringar runt en fix punkt kan utföras med hjälp av fyra olika exponentmängder, underline{Q}_0, underline{S}_0, overline{S}_0 och overline{Q}_0, som beskriver hur vikten beter sig i närheten av denna punkt och i viss mån ger rummets lokala dimension.För att kunna dra nytta av exponentmängderna är det bra att veta vilka kombinationer av dessa som kan förekomma. För att få fram nya kombinationer använder vi olika sätt att mäta volym av klot med varierande radier. Dessa mått är definierade genom olika vikter.Det har tidigare funnits ett fåtal exempel på hur olika kombinationer av exponentmängderna kan se ut.

Food traceability system for Swedish origin food items : an assessment of the application ?våga fråga - få en bonde på köpet? from a farmer perspective

In June 2013 a debate concerning the consumers? right to a label of origin on food packages was held in the Swedish parliament (www, Riksdagen, 2014). The debate was sparked by some food scandals where labelling was falsely used, claiming something that was not true ? the horse-meat scandal, frozen strawberries infected by Hepatitis A, pork sold as beef, etc. These cases were not only wrong in terms of food safety, but also fraudulent and threating consumers? right to fair origin labelling.

OLED : Evaluation and clarification of the new Organic Light Emitting Display technology

Organic Light Emitting Displays (OLEDs) are a new type of thin emissive displays predicted to possess superior properties to existing techniques e.g. Liquid Crystal Display (LCD). The main advantages are low power consumption and a thin display structure. This report contains an explanation of the emissive OLED technology, its functionality and the physics of the organic layer structure in an OLED. The technology is described with respect to the two classes of organic materials used in displays, small molecules and conjugated polymers.

Long-term Storage of Starch Potato and its Effect on Starch Yield

Lyckeby Starch AB is a farmer-owned company that produces products based on potato starch. In order to increase their production efficiency and their international competitiveness the company is investigating the possibilities of keeping their factories open longer. To achieve this, potato has to be stored for a longer period of time than what is practiced today. Starch potato is usually stored in large piles covered by straw and plastic, either in the field or on the farmyard. The objective was to examine in what way starch yield (starch content*tuber weight) in three different potato varieties was affected by storage in two different types of storage piles. The potato was stored for three months in total and starch content and tuber weight were controlled throughout the period. Stored tubers were also visually examined and prescense of mechanical damage as well as wet rots and dry rots was recorded. Bacteria and fungi were isolated and identified. In general, varietal differences were greater than differences between the storage piles.
