1. Extended impregnation kraft cooking of softwood : Effects on reject, yield, pulping uniformity, and physical properties
Sammanfattning : Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. LÄS MER
2. Isomeric yield ratios in nuclear fission
Sammanfattning : Isomeric yield ratios (IYR), referring to the relative yield of the high spin states of a nucleus to the total yield of all observed states, is an observable of nuclear fission that has the potential to improve our understanding of the fission dynamics. Apart from that, systematic observations of IYRs can also contribute to other areas, such as the validation of fission models, modelling of the r-process in stellar nucleosynthesis, studies of the antineutrino mixing angle, the safety of present-day nuclear reactors, and the design of advanced reactor systems.

3. Aspects of extended impregnation kraft cooking for high-yield pulping of hardwood
Sammanfattning : The long-term trend regarding wood is an increase in price. Because wood contributes to a large part of production costs, the efficient utilisation of wood is greatly desired to reduce production costs for kraft pulp producers. During the 1990s, the development of improved modified kraft cooking began, which led to higher yields. LÄS MER
4. Torque and angle controlled tightening over the yield point of a screw
Sammanfattning : .... LÄS MER
5. The relationship between climate, disease and coffee yield: optimizing management for smallholder farmers
Sammanfattning : Climate change and diseases are threatening global crop production. Agroforestry systems, which are characterized by complex multispecies interactions, are considered to provide nature-based solutions for climate change mitigation and pest and disease regulation. LÄS MER
