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.

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med hjälp av UV-ljus och ozon

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

Barns delaktighet och inflytande i den pedagogiska dokumentationen i förskolan

The purpose of this study is to find out what the educators idea of educational documentations in ratio to childrens inclusion and impact in pre-school are, together with the child's own perception of the concepts of documentation. We proceeded from the following issues: What are the significance of educational work according to the teachers? What is the teachers idea of a childs impact and inclusion in educational documentation? In what way do the children have influence over, and inclusion in educational documentation? What are the childrens feelings of the documentations? In order to find answers to our questions, we used qualitative examinations consisting of seven educators and seven children from various pre-schools in Stockholm, and thereby, we have analyzed our results. As our theoretical frame, we used ourselves of Vygotskijs and Säljö's sociocultural perspective that is about "progress and learning", which is achieved by interaction and cooperation in a social context. The result shows that the aim of educational documentation is to reveal the childs development and learning, and also to involve the parents by putting up documents on the wall.

Från papper till pixel : Kvarnholmen studerad utifrån historiska kartor med stöd av GIS

Sweden has a long tradition as a mapmaking nation. Tens of thousands of historical maps,dating from the sixteenth century and onwards are still preserved in archives today, providinga rich resource for studies of city growth and changes in the landscape through time. For morethan ten years an effort has been made by public authorities to transfer this material frompaper onto digital media. Due to modern technology, as for example GeographicalInformation Systems (GIS), researchers have been given improved possibilities to study andanalyze this material. This study uses a qualitative approach, based on both literature studiesas well as map studies.

Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns

The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.

Märstaån ? ett vattenlandskap : Är våtmarker och dammar vägen framåt?

The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed.  The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas.  The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.

Skogspolitik i Sverige

For a long time the Swedish forests were used by the landowner?s mainly for providing wood to the household itself. The wood was not, to a greater extent, considered a product to be sold. During the 1800s the industrial era led to a demanding need for wood in the industry and thus the use of forest, forest production kicked off. The forest production was not regulated by law, which led to a differentiated forest production over the whole country without consideration of re-growth.

: En undersökning om hur tillväxtstrategier kan tillämpas med hänsyn till hållbar utveckling

Att börja växa som företag är svårt, inte minst inom klädindustrin där det granskas stygn för stygn av media. Under de två senaste decennierna har fler klädföretag börjat arbeta med hållbar utveckling. Det som tidigare har genererat tillväxt från den industriella utvecklingen går emot dagens hållbarhetstänk, som har blivit viktigare i klädföretagen. Samtidigt behövs tillväxt hos klädföretag för att konkurrera på den mer globaliserade marknaden. I denna studie undersöks det hur tillväxtstrategier kan tillämpas i ett klädföretag som arbetar med hållbar utveckling.

Dikesavståndets inverkan på såtid och skörd

All arable land in Sweden need a proper drainage for an effectively agriculture to take place. Of all arable land in Sweden, about 50% is naturally drained and 50% need artificial drainge. More than half of the tile drained area is in need of new drainage or renewed drainage. A good drainage improves farming and crop growth and increases the opportunity to achieve a high and safe harvest level. Future climate change and agriculture size rationalization will increase the need for good drainage. In this paper, two trials with three drainage distances, performed at Lanna experimental station, were analyzed using a mixed linear model.

Institutions Matters - En teoriprövande studie om institutionell struktur och ekonomiskt välstånd inom transitionsländerna

This thesis analyzes and discusses the role of institutions concerning countries' abilities to create economic wealth. The countries that we are analyzing are the former members of the Warsaw pact and former Yugoslavia. These countries are referred to as transition countries. In order to analyze the transition countries institutional structure we are using Douglass C. North's theory regarding institutions and institutional building.

IFRS 2005 : Övergången till IFRS i små svenska börsnoterade bolag

Bakgrund: Dagens näringsliv har fått en alltmer global prägel och de flesta börsnoterade företagen har internationella kontakter i någon form. EU- parlamentet har beslutat att alla bolag vars aktier eller skuldebrev är noterade på en börs ska upprätta sin koncernredovisning enligt International Financial Reporting Standards, IFRS, och detta måste följas av samtliga noterade bolag inom EU senast 1 januari, 2005. Syfte: Uppsatsens syfte är att beskriva och förklara hur väl anpassade små svenska företag är och vilka eventuella problem de har i anpassningen till IFRS. Syftet är vidare att skapa en beskrivande modell över hur företagens anpassningsprojekt bör utformas. Avgränsningar: Med små företag avses i denna uppsats företag som är noterade på de officiella listorna och har en omsättning som understiger 200 miljoner kronor.

Vad kostar deltid? Kvinnors deltidsarbete ur ett pensionsperspektiv

Mothers of small children often work part-time in Sweden. Since old age pensions are based on lifetime income, part-time work leads to lower pensions, as long as there is no compensation from non-actuarial benefits such as minimum pensions. In this paper, I investigate whether different components of the Swedish pension system provide incentives for part-time work among women. The analysis is performed through a simulation of future pensions for 9 typical women in a certain cohort. For three levels of education, I compare pensions of women with different labor market participation rates in different growth scenarios.

The role of cell cycle control mechanisms in regulated and sustained cell proliferation

The cell cycle is the time a cell spends between two cell divisions. The cell cycle includes several parallel processes, all of which must be completed before a cell is mature for dividing. In the first place, all subcomponents (RNA, protein and membrane lipids) need to double in quantity and this occurs continuously through the cell cycle. Furthermore, the genome and some chromosomal proteins must double and this take place during a limited interval in the middle of the cell cycle (S-phase). On either side of the S-phase are two "gaps" which is called G1 and G2. When the cell has passed a point in the G-phase they are irreversibly programmed to progress through the remaining of the cell cycle and will undergo the next cell division. When a cell have passed a point in the G1 phase, approximately four hours after mitosis, a normal cell is in a state of indecision.

Osäkerheten i ombyggnationsprojekt : Case Study av ombyggnation av Praktikertjänst huvudkontor

The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.
