  1. 11. Hearing by Bone Conduction. Physical and Physiological Aspects

    Author : Stefan Stenfelt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Bone conduction as a phenomenon, physically and physiologically, is of vital importance in both the diagnosis of a hearing impairment and the development of bone conduction hearing aids. Understanding hearing by bone conduction is difficult, involving sound transmission by wave motion in a complex geometrical structure of layered bone covered with soft tissue and cartilage, finally received by the highly delicate cochlea.

    Keywords : nanoparticles; cobalt; stainless steel welding fume particles; biomolecules; metal release; trophic transfer; adsorption; agglomeration; algae; nanopartiklar; kobolt; rostfritt stål svetsrök partiklar; biomolekyler; metallfrigöring; trofisk överföring; adsorption; agglomerering; alger; Kemi; Chemistry;

    Abstract : Nanoparticles (NPs) and nanomaterials (NMs) are present everywhere in the environment. They can form both as an act of nature and during human activities. Various kinds of NPs and NMs are engineered for different applications in the ongoing development of nanoscience and technology. READ MORE

  4. 14. Ambulance Work : Relationships between occupational demands, individual characteristics and health-related outcomes

    Author : Ulrika Aasa; Ewa Wigaeus Tornqvist; Umeå universitet; []
    Keywords : ambulance; autonomic reactivity; body size; cortisol; demand-control-support; emergency personnel; fitness; gender; heart rate variability; low-back pain; neck-shoulder pain; occupational; physical capacity; work simulated test; worry; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Although musculoskeletal disorders (MSDs) and other health complaints are an occupational problem for ambulance personnel, there is a lack of knowledge regarding work-related factors associated with MSDs and other health complaints. The overall aim of this thesis was to investigate the relationships between occupational demands, individual characteristics and health-related outcomes among ambulance personnel. READ MORE

  5. 15. Seed dormancy and germination in an ecological context : comparative studies of annual weeds

    Abstract : Germination ecology studies, i.e. studies of interactions between characteristics of the seeds and environmental circumstances, provide understanding of spatial and temporal patterns of emergence of wild species, as weeds in the field. A large number of species have seed dormancy, i. READ MORE
