The purpose of these theses is to show the financial economical situation during the change from conventional dairy production to ecological production. The thesis is accomplished by collecting information from literature and interviews where needed. The target group of these theses is dairy producers who will transform their production from conventional dairy production to certified ecological dairy production. The theses emphasise on the economic situation during the adjustment years. For this I have studied a presently producing dairy farm.

Deregulation on the market for agricultural products leads to a more globalised market with increasing price fluctuations. This, in turn, places the farmer in positions influenced by new risks but also improved opportunities. The farmers are faced by uncertainty in terms of financial outcome. To be able to utilise these new market conditions it becomes increasingly important for farmers to continuously follow the price trend, and to develop strategies how to manage the risks exposed by a volatile market. Farmers with different conditions perceive risk in different ways. Hence, their risk management behaviour will vary.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.

The tribo system ice-curling stone was investigated in order to understand the mechanisms behind the stones' behavior on the ice sheet. The problem with non-identical stones should also be addressed.The stone curls, that is, its sliding path deviates from a straight line to the right for a clock-wise rotation and to the left for a anti-clock-wise rotation. Several mechanisms to explain this behavior have been proposed over the years but none has been successful.By carrying out experiments at the local curling rink and studying silicon castings of ice- and stone-surfaces with scanning electron microscopy and vertical scanning interferometry, it has been decided that the curl is not due to dry friction, ice-debris or the difference in friction on the left and right side of the stone. The side force comes from the fact that the friction is higher at the back of the stone than at the front.The contact between stone and ice is never completely dry, nor in the hydrodynamic lubrication regime. It is probably a combination of hydrodynamic lubrication and a contribution from mechanical scratching of the ice.

Frågan om revisorns oberoende har historiskt sett alltid varit en aktuell fråga och är idag själva grunden för revisionsyrket. Revisorns oberoende har blivit kraftigt ifrågasatt under den senaste tiden, vilket beror på en rad olika redovisningsskandaler runt om i världen. För att återupprätta allmänhetens förtroende för yrket har lagstiftare implementerat nya lagar och regler. EUs svar på revisorns bristande trovärdighet är intern rotation av påskrivande revisor och nyckelpersoner inom revisionsteamet. I Sverige gäller lagen om den interna revisorsrotationen för noterade bolag.

This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.

Skiljer sig utvecklingen av spädbarns förmåga att planera griprörelser mot ett objekt relativt att anpassa handen till objektets rotation? Nitton spädbarn i åldrarna 6 och 10 månader studerades. Spädbarnen grep mot en stav i rotation och deras griprörelser registrerades med hjälp av ett ProReflex system (Qualisys). Såväl handens hastighet fram mot staven som handens vridningshastighet beräknades och delades in i rörelseenheter bestående av en accelerationsfas och en inbromsningsfas. Resultatet visar att antalet enheter sjunker med ökande ålder för båda hastigheterna.

The quality of bread wheat is a large subject to study. The quality rests on two legs. The first one is the inheritance of specific characters, which can be influenced through plant breeding and type of cultivar. The other one is the environmental influences, such as Crop rotation, nutrition, harvest and storage. The latter factors are possibly to affect through cultivation practices, while other factors are not possible to influence on for the grower, such as seasonal changes of weather and the soil content.

The boiling properties are an important quality issue of the potato. In order to obtain adequate boiling properties the growth of the potato needs to be controlled and interrupted at the right time. However, it is difficult to determine when to stop the growth. Specific gravity can easily be measured and can sometimes be used as a tool for estimating the boiling properties. This report discusses different aspects of the specific gravity of the potato and how it can be used as a tool to determine the appropriate time for vine killing.

The Swedish cooperative Lantmännen Ekonomiska Förening has initiated a project labelled "Operation Blåljus" that includes an extensive program for closing down elevators. The number of elevators will be reduced from 92 to approximately 15 after harvest of 2007. The objective of Blåljus is to increase the price of grain with 10 öre/kg. A project has been initiated at the Lantmännen Grain division where the purpose is to provide the farmers with support in their decisions and practical advice how they can load a 35 ton grain truck on 30 minutes. The result from the project will serve as a support system to the farmer in his ambition to achieve cost efficient systems to load a truck with grain on the farm.

Agricultural land could be polluted by radioactive substances after a fallout. We would then need information about the level of contamination to decide whether the crops could be utilized as food under these circumstances. In an experiment carried out during the 1990ies the retention of 134Cs in potato haulm and the transfer to the tubers were studied. The experiment was carried out during three consecutive years. The plants were cultivated in pots under field conditions and the artificial deposition was sprayed directly onto the potato haulm at different times during the growing season.

The payment for produced grain is constantly going down in price. It is important for farmers to become more effective in cultivating more land in a shorter time perspective. At the same time we have to calculate with the risk of getting lowered subsidies from the EU. This is why I would like to find out the possibilities for establishing winter wheat without ploughing. I hope to find a difference in the number of plants due to different soil preparations. With this experiment I expect to find out whether I can establish winter wheat at a lower cost, with the same numbers of plants per square meter.

It is important for today?s farmers to minimize the costs for crop establishment, because of decreased prices and support from the EU. Farmers, who plow in autumn on heavy clay soil, often do some kind of tillage in autumn to get better soil structure before spring seeding. This is especially important when growing small seed crop, e.g. sugar beet and oil plants.
