“…This is, to the best of our knowledge, the first prospective and controlled study to assess the time dependent effects of intermittent fasting on microvascular function in humans. The study design of our study differs markedly from previous numerous uncontrolled trials on this topic, were some cardiovascular parameters and laboratory measures were often recorded before and after fasting without much standardization [19,20,[34][35][36]. In our study, measures were carefully reiterated to determine if the effects of fasting persisted thereafter.…”

Background: Reduced endothelial nitric oxide bioavailability, a hallmark of endothelial dysfunction, is commonly encountered in cardiovascular diseases. Intermittent fasting reduces serum markers of oxidative stress, while nitric oxide levels may rise. Whether this translates into persistent improvements in endothelial function is unknown. The aim of the study was to address the effects of intermittent «Ramadan-type» fasting on endothelial function, nitric oxide bioavailability, biological parameters and blood pressure.

Established high temperature operation of gas foil bearings (GFB) is of great interest for gas turbine applications. The effects of (high) shaft temperature on the structural stiffness and mechanical energy dissipation parameters of a foil bearing (FB) must be assessed experimentally. Presently, a hollow shaft warmed by an electric heater holds a fioating second generation FB that is loaded dynamically by an electromagnetic shaker. In te.sts with the shaft temperature up to 184°C, the measurements of dynamic load arid etisuing FB defiection render the bearing structural parameters, stiffness and damping, as a function of excitation frequency and amplitude of motion. The identified FB .stiffness and viscous damping coefficients increase with shaft temperature due to an increase in the FB assembly interference or preload. The bearing material structural loss factor best representing mechanical energy dissipation decreases slightly with shaft temperature while increasing with excitation frequency. Separate static load measurements on the bearing also make evident the preload of the test bearing-shaft system at room temperature. The loss factor obtained from the area inside the hysteresis loop of the static load versus the defiection curve agrees remarkably with the loss factor obtained from the dynamic load measurements. The static procedure offers substantial savings in cost and time to determine the energy dissipation characteristics of foil bearings. Post-test inspection of the FB reveals sustained wear at the locations, where the bumps contact the top foil and the bearing sleeve inner surface, thus, evidences the bearing energy dissipation by dry friction.

Dense and gastight dead-end tubular Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3-d (BSCF) membranes were fabricated by thermoplastic extrusion. Optimal feedstocks for the extrusion of dead-end tubular structures were obtained for a feedstock consisting of 89.83 wt% BSCF powder, 5.63 wt% ethylene vinyl acetate (EVA), 3.56 wt% paraffin wax (PW), and 0.98 wt% stearic acid (SA). Thermogravimetric analysis (TGA) was used to determine the thermal characteristics of the feedstock and to characterize the amount of binder removed during the wicking step. Straight and round dead-end tubular membranes with wall thickness of 0.5 mm could be achieved after sintering. The gastightness test showed that the membranes were leak-tight up to a pressure of 35 bar.
