1. 6. On cardiovascular responses to hypovolemic circulatory stress. An experimental study in man

   Författare :Henrik Olsen; Helsingborg Kliniska Vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetology; secreting systems; Endocrinology; vein.; type 1 diabetes; skeletal muscle; LBNP; compliance; CFC; Ageing; baroreceptor; Endokrinologi; sekretion; diabetologi; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : Aged subjects have a decreased tolerance to hypovolemia, which could contribute to their increased cardiovascular morbidity. One possible etiological factor might be an age-related reduction in the efficiency of the baroreceptor reflex axis. LÄS MER

3. 7. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard

   Författare :Wen Jiang; Stergios Adamopoulos; Sheikh Ali Ahmed; Sergej Medved; Carsten Mai; Johannes Konnerth; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bark; Catalysts; Industrial side-streams; Liquefaction; Oat husks; Optimization; Particleboards; Polyurethane; Polyhydric alcohols; Wood adhesives; Wood sawdust; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

4. 8. The Hydrodynamics of Waterjet/Hull Interaction

   Författare :Arash Eslamdoost; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trim angle; vena-contracta; transom clearance; net thrust; waterjet hull interaction; waterjet propulsion; capture area; exit drag; non-linear free-surface; intake drag; gross thrust; sinkage; streamtube; RANS; thrust deduction; potential flow; VOF;

   Sammanfattning : The objective of the present investigation is to explore the physics behind the waterjet/hull interaction, and in particular the negative thrust deduction often reported in the semi-planing speed range. Another objective is to propose a validated numerical technique for computing the hydrodynamics of waterjet-driven hulls. LÄS MER

5. 9. Cardiovascular responses to hypovolemic circulatory stress in women : With special reference to venous compliance and capacitance

   Författare :Marcus Lindenberger; Toste Länne; Peter Friberg; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; Kardiologi;

   Sammanfattning : Acute haemorrhage is a leading cause of death in trauma. Young women (YW) seem more susceptible to hypovolemic circulatory stress than young men (YM), but the underlying mechanisms are not clear. LÄS MER

7. 10. Exploring the resilience in coral reefs

   Författare :Jerker Lokrantz; Magnus Nyström; Morgan Pratchett; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coral Reefs; Resilience; Functional Groups; Vulnerability; Overfishing; Ecosystem Indicators; Tanzania; Zanzibar; Marine ecology; Marin ekologi; naturresurshushållning; Natural Resources Management;

   Sammanfattning : Considering the unprecedented global decline of coral reefs concerns about their future existence are well-justified. Safeguarding ecological resilience (i.e. the capacity of ecosystems to absorb disturbance without changing their identity) has become a prime goal for management in order to combat further degradation of coral reefs.
