    Abstract : The history of surgery is nearly as old as the human race. Control of wound infection has always been an essential part of any surgical procedure, and is still an important challenge in hospital operating rooms today. For patients undergoing surgery there is always a risk that they will develop some kind of postoperative complication. READ MORE

  2. 2. Design and Control Parameter Optimization of Soft Ankle Exoskeleton for People with Dropfoot and Excessive Inversion

    Author : Xiaochen Zhang; Elena Gutierrez-Farewik; Ruoli Wang; Susanne Palmcrantz; Shaoping Bai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Assistive device; Biomechanics; Gait impairment; Movement augmentation; Assistiv enhet; Biomekanik; Gångnedsättning; Rörelseförstärkning; Teknisk mekanik; Engineering Mechanics;

    Abstract : Wearable robotics and exoskeletons have been explored for their efficacy in physical rehabilitation and for assistance in daily activities for people with motor disorders. The overall objective of this thesis is to design a powered soft exoskeleton for people with dropfoot and excessive inversion, commonly after a stroke, and to optimize the control parameters for each individual while considering different dimensions.

  3. 3. Allochthonous and autochthonous carbon sources of lake bacterioplankton

    Author : Emma Kritzberg; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marinbiologi; limnologi; akvatisk ekologi; aquatic ecology; marine biology; Hydrobiology; bacterial community composition; bacterial growth efficiency; bacterioplankton; carbon subsidy; dissolved organic carbon; limnology;

    Abstract : Organic substrates for pelagic bacteria are derived from dissolved organic carbon (DOC) in the water column that originates either from primary production from within the lake itself (autochthonous), or import of organic matter from the terrestrial watershed (allochthonous production). This thesis addresses the utilization of allochthonous versus autochthonous carbon (C) sources by lake bacterioplankton. READ MORE

  4. 4. The prey perspective - behaviour and appearance in a world of predators

    Author : Johan Ahlgren; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Local adaptation; predator regime; phenotypic plasticity; inducible defence; mortality; animal personality; predator; trait-compensation;

    Abstract : The varieties of prey phenotypes that have been revealed in nature are vast and many of these phenotypes are the result of the selective force that predators have had on prey traits in the past. Even within species and populations we see variations due to both differences in the selection forces they live under but also due to individual trait variation. READ MORE

  5. 5. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

    Author : Kim H. Berndt; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

    Abstract : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. READ MORE
