The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

The thesis aims to investigate the farmer?s perception of currency hedging and interest rate bonds and to investigate the farm size of companies categorized by number of acres, has no effect on this. The work also aims to gain an insight into what active farmers consider to be important what to consider when they choosing a bank and a personal banker. The work is based on the survey and has been supplemented by a literature review on the subject. For the survey were selected out randomly 50 farmers with Agriculture and Rural Management education. The requirement of the farmers was that they should be farmers by profession, and also made sure that the farmers of various sizes came with. We got a total of 32 responses within the set response time we said, which was better response than we expected. When the final result came we ranged the farms in a size range. We found out that all farmers in the study diligently follow the market and are easy to assimilate new ideas, providing opportunities to profitability of their business with the different instruments that are available on both the financial level and farm level. The investigation revealed that the major in favor of having a personal banker. They think it´s good to have a special plug to turn to who has knowledge and experience of how the agriculture sector operates.

Government regulations and customs duties restrict the import of trucks to some of the markets to which Scania tries to sell their trucks. The distribution problem due to these regulations is solved by the foreign assembly department, KD, at Scania. This means that competence is needed and costs are added not related to Scania's core operations.The aim of this master thesis has been to analyse and to evaluate alternative ways of managing the packing operations considering cost, quality and work organisation. To study and examine the work methods and operations of today and also to present methods measuring the operations effectiveness and productivity.We have used the system approach to maintain totality and to understand the component's relation to this totality. Field studies combined with studies of relevant literature and studies of other companies operations have given us the knowledge and the understanding of the packing operations needed.

The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.
