… and unselected semen. Since the NucleoCounter SP-100 is a relatively new machine a comparison was also made with flowcytometry regarding viability. Concentration measured with NucleoCounter SP-100 was compared by the use of manual counting with the Bürker chamber. The results …
… hard. In this thesis we evaluate the alternatives of investing in new machinery; utilize the current machinery better by using them more days annually or through a shift work system. Finally we evaluate a combination of these. The study has two purposes. First to help the …
det teknologiska traumat i J.G. Ballards The Atrocity Exhibition
… it proves to be the agent of his trauma, but also functions as his shield. The machine is thus in a position of the hinge, the point in a structural system that both enables and deconstruct the system. In the same position we find the woman. She is the very epicentre of the …
… The picking is done by hand, but the rest of the processes are handed by machines which consumes energy. This conduce emissions like carbon dioxide, methane gas and nitrous oxide. The cotton farming is settled in Peru, and from there the textile is sent via Sweden to Estonia to …
Detta är ett examensarbete som genomförts hos Göteborg Energi AB och syftar till att utreda omkryogen uppgradering av biogas med fördel kan ske genom att producera nödvändig kyla medvärmedriven absorptionskylmaskin. Göteborg Energi är en av tre parter som tillsammans ska bygga …
… after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials. The asphalt materials were leached by water during 24 …

… necessary electrical for the control system of the vehicle. The rebuild of the machine to a complete electrical machine was successful and the performance is similar to the original construction but easier to drive, less noisy and more environmental.
… such as acceleration, temperature and speed conclusions can be drawn on machinery health. The aim is to evaluate hardware and software solutions for a possible future product. Based on a requirement specification a proper hardware design has be developed. The hardware consists …
… be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined …
… to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester’s path by creating a ”log plot”. This feature was not used to its full potential however, since only one out of eight of the forwarders …
… in Swedish forestry. This study compare different concepts concerning machinery, namely two general-purpose excavators of different sizes, 8 tonnes and 15 tonnes, versus a dedicated machine constructed solely to deal with ditch-cleaning. The machines were tested on rough as well …

… tree volume and the proportion of Lodgepole pine of harvested biomass. At machine cost of 550 SEK/E0-hour, a forest fuel prize of 210 SEK/m3solid, a forwarding distance of 100 m, a productivity of 0.88 ODt/E0-hour and harvested tree size of 19 dm3solid the profitability was -1 …
… that belonged to their position. The respondents all agreed that the forest machine operators was the ones that had been most affected when Sveaskog started to extract logging residue. There where communication obstacles that prevented the person that worked with forwarding …
