… trees not suitable for pulpwood are removed to simplify the later work of the harvester. The study compares the economic results from thinning of four parcels each treated differently regarding harsh or light pre-clearance and extraction of only pulpwood, or both pulpwood and …
… the county of Östergötland and four from the county of Västergötland.Fungi on harvested broad beans were identified by using terminal restriction fragment length polymorphism, (T-RFLP), where the internal transcribed spacer (ITS) region in the fungal DNA, which is unique for …
… with possible explanations, like the need of provisions, trade goods, harvest cycles in Africa and America, though the essay doesn't have any pretensions of proving actual causal relations, just that the seasonality of the slave trade coincided with other seasonal cycles.
… chainsaw lubricant with a new unusual base fluid. A field test with a tree-harvester shows unsatisfactory low temperature properties and high wear. In this work the viscosity, price and pour point of different combinations of the given base fluid and three other base fluids have …

… has been to find a cheaper wayto open the large engine hood of the company’s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous …
… radiation from the sun is an interesting alternative. One way of harvesting this energy is by using solar cells, devices that generate DC current when exposed to electromagnetic radiation. The goal of this master’s thesis was to design a solar powered power supply to Syntronic …
effects of maturity stage at harvest and feeding strategy
Trakealkollaps är relativt ovanligt förekommande hos hästar men är något vanligare hos småvuxna ponnyraser. Sjukdomen har ett progressivt förlopp och är ofta långt framskriden innan respirationssymtom som missljud, hosta och dyspné uppkommer. De tillgängliga …
… 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 included in the study had computers that were compatible …
