Early and late systolic wall stress differentially relate to myocardial contraction and relaxation in middle-aged adults: the Asklepios study Ghent University
Experimental studies implicate late systolic load as a determinant of impaired left ventricular (LV) relaxation. We aimed to assess the relationship between the myocardial loading sequence and left ventricular (LV) contraction and relaxation. Time-resolved central pressure and time-resolved LV geometry were measured with carotid tonometry and speckle-tracking echocardiography, respectively, for computation of time-resolved ejection-phase ...
Evaluation of cold stress of young industrial chicory (Cichorium intybus L.) by chlorophyll a fluorescence imaging. II. Dark relaxation kinetics Research Institute for Agriculture, Fisheries and Food Ghent University KU Leuven
Industrial chicory, Cichorium intybus L., has rather poor early vigour under the typical early spring morning conditions of low temperatures and high light intensity. Screening tools are being developed to assess the cold tolerance/sensitivity of young industrial chicory plants under these conditions. Refinement of such tools requires better understanding of the plants' physiological responses. In this paper we discuss the effects of growth ...
Effects of Stress and Relaxation on Central Pain Modulation in Chronic Whiplash and Fibromyalgia Patients Compared to Healthy Controls Vrije Universiteit Brussel Ghent University University of Antwerp
BACKGROUND: Compelling evidence has demonstrated that impaired central pain modulation contributes to persistent pain in patients with chronic whiplash associated disorders (WAD) and fibromyalgia (FM). However, there is limited research concerning the influence of stress and relaxation on central pain modulation in patients with chronic WAD and FM.
OBJECTIVES: The present study aims to investigate the effects of acute cognitive stress ...
Strain-rate sensitivity and stress relaxation of hybrid self-reinforced polypropylene composites under bending loads KU Leuven
© 2018 Elsevier Ltd The strain-rate sensitivity and stress relaxation of self-reinforced polypropylene (SRPP) and hybrid carbon fibre/SRPP composites were analysed under bending loads. For this purpose, three point bending static tests were performed at room temperature and displacement rates of 200, 20, 2, 0.2 and 0.02 mm/min. Tests of stress relaxation were also carried out, where a fixed strain was applied and the stress was recorded during ...
Nonmonotonic Stress Relaxation after Cessation of Steady Shear Flow in Supramolecular Assemblies Hasselt University KU Leuven
Stress relaxation upon cessation of shear flow is known to be described by single-mode or multimode monotonic exponential decays. This is considered to be ubiquitous in nature. However, we found that, in some cases, the relaxation becomes anomalous in that an increase in the relaxing stress is observed. Those observations were made for physicochemically very different systems, having in common, however, the presence of self-associating units ...
Temperature and time dependence on recovery stress relaxation in nickel titanium wire during isothermal holding at high temperatures KU Leuven
In this study, the influence of kinematically constrained thermal cycling (heating, isothermal holding and cooling) on the recovery stress in annealed nickel titanium wire was investigated. A 4% pre-strained nickel titanium wire was heated to temperatures (150, 200, 250 and 300 °C) much higher than the austenite finish temperature. It was observed that the maximum recovery stress obtained at different conditions decreases significantly after the ...
