1. 16. Articular distension in arthroscopy : an experimental study on intra- and extra-articular effects of pressure

   Författare :Anders Sperber; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Arthroscopy; intra-articular pressure; in vivo measurements; knee joint capsule; tensile properties; stress-strain; multicompartmental pressures; lower leg venous blood flow; ultrasound; acromioplasty; intra-muscular pressure; fluid absorption; shoul;

   Sammanfattning : The purpose of this thesis was to analyse the effects of various intra-articular pressures (IAP) on soft tissues and to provide guidelines for the choice of safe infusion pressures during arthroscopy. The tensile properties of the knee-joint capsule were recorded from stress-strain-relaxation tests within 170 mmHg IAP. LÄS MER

3. 17. Atomistic Computer Simulations of Melting, Diffusion and Thermal Defects in High Pressure Solids

   Författare :Sergio Davis; Anatoly Belonoshko; Börje Johansson; Leonid Zhigilei; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

   Sammanfattning : The present work describes the use of atomistic computer simulations in the area of Condensed Matter Physics, and speci cally its application to the study of two problems: the dynamics of the melting phase transition and the properties of materials at extremely high pressures and temperatures, problems which defy experimental measurements and purely analytical calculations. A good sampling of techniques including classical and rst-principles Molecular Dynamics, and Metropolis Monte Carlo simulation have been applied in this study. LÄS MER

4. 18. Tools for protective lung ventilation. The elastic pressure-volume curve and aspiration of dead space

   Författare :Edoardo De Robertis; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; radiology; tomografi; medicinsk instrumentering; radiologi; Klinisk fysiologi; tomography; medical instrumentation; Respiratory system; Andningsorganen;

   Sammanfattning : Ventilator-induced lung injury (VILI) may contribute to morbidity and mortality of acute lung injury (ALI). Lung protective ventilation (LPV), that reduces VILI, may involve low tidal volume (Vt). Particularly low Vt is possible if dead space ventilation is reduced e.g. LÄS MER

5. 19. Effect of Compactive Effort on the Behaviour of a Gypsiferous Subgrade Soil

   Författare :Dina K Kuttah; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gypsum; Soil; Clay; Compaction; California bearing ratio; Triaxial; Moisture content; Pore water pressure; 62 Road: Soil mechanics; 62 Road: Soil mechanics;

   Sammanfattning : Presented in this thesis is a study of the effect of compactive effort and long-term soaking on strength, stiffness and deformation characteristics of a gypsiferous subgrade soil from Kirkuk city.The tested soil is sandy lean clay (CL) according to the Unified Soil Classification System and A-6 (6) soil according to AASHTO soil classification system.

7. 20. Decision support for sustainable water security

   Författare :Karin Sjöstrand; Dale Whittington; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; risk assessment; decision support; water security; water availability; multi-criteria decision analysis; water scarcity; sustainability; drinking water supply; cost-benefit analysis; marginal abatement cost curves;

   Sammanfattning : Society’s large dependence on water, in combination with climate, socio-economic and demographic changes, places a massive pressure on our freshwater resources. As a result, water crisis, defined as a significant decline in the available quality and quantity of freshwater, is now considered to be among the most critical global risks to society. LÄS MER
