The physiological response induced by acute prolonged sitting is not fully understood. Therefore, we examined the effects of 8-h constant sitting on microcirculation and associated factors in the lower extremity among healthy males. We also evaluated the protective effects of lower-pressure thigh-length elastic compression garments on these paramet...

Treated wastewater in micro-irrigation is a promising approach that could be used to decrease the pressure on good quality water resources. However, the clogging of such systems due to biofilm development and chemical precipitation constitute a constraint with the use of treated wastewater (TWW) and lead to lower irrigation system performance. The ...

Robust micro machined high temperature gradient calorimetric (HTGC) transducers were developed for flow separation control. Based on thermal principle, the transducers measure the mean and fluctuating bidirectional shear stress that is particularly useful for flow separation detection. More than a hundred micro-sensors were simultaneously micro-mac...

Soil bioengineering techniques for riverbank protection are nature based solutions that have to fulfil most of the ecological functions of a natural riverbank, and they have also to achieve a sustainable erosion control function. Nevertheless, there are very few existing sizing methods, ant this lack is the main stand in the way of developing bioen...

Recent research is showing growing interest in low-power electromechanical de-icing systems and, in particular, de-icing systems based on piezoelectric actuators. These systems use the vibrations generated by piezoelectric actuators at resonance frequencies to produce shear stress at the interface between the ice and the support or to produce tensi...

In the context of global change reaching the general hydro-ecological and biodemographic parameters, micro-irrigation used in agriculture with treated wastewater is a promising approach to reduce water expenditure. However, the clogging of micro-irrigation systems constitutes a constraint on the use of these waters containing micro-organisms, nutri...

In landfills, geosynthetics (GSYs) are implemented on the bottom and side slopes of the waste cells to prevent the leachate infiltration into groundwater, as a lining system. In piggy-back landfill expansions (PBLE) where a new landfill is built over an older one, this lining system can be subject to high tensile forces (tear) and interface shear s...

Shear stress is determined by three physical components described in a famous triad: blood flow, blood viscosity and vessel geometry. Through the direct action on endothelium, shear stress is able to radically interfere with endothelial properties and the physiology of the vascular wall. Endothelial cells (ECs) have also to sustain biochemical stre...

Endothelial cells undergo a rapid cell-cell junction inclination following exposure to atheroprotective unidirectional flow. In contrast, atherosclerotic lesions correlate with a heterogeneous distribution of the junctional wall inclination in cells exposed to time-varying, reversing, and oscillatory flow as well as to low mean shear stress. Howeve...

Bonded joints are used in several industrial applications as a surrogate of more expensive repairs, but their reliability must be ascertained. Failure in a bonded joint mainly occurs in the adhesive due to stress concentrations that directly depend on the adhesive thickness. In practice, it is difficult to ensure a good accuracy of the final adhesi...
