Localized calcium events in the endothelial cells (EC) can modulate smooth muscle cell (SMC) calcium (Ca2+) and membrane potential dynamics through release of endothelium derived hyperpolarizing and relaxing factors. Ca2+ levels in the smooth muscle cell (SMC) determine its contractile ... En savoir plus

Lake Victoria is the largest tropical lake in the world and is very important for environment and economy in East Africa. The hydrodynamic processes in the shallow (40-80 m deep) water system are unique due to its location at the equator which makes Coriolis effects noticeable also for ... En savoir plus

Previous research into acoustic omnidirectional absorber (AOA) has shown the feasibility of forming acoustic black hole to guide the incident wave into the central absorptive cavity. However, major restrictions to practical applications exist due to complexity of designing metamaterials ... En savoir plus

Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by ... En savoir plus

For the last two centuries, the conventional Fourier heat conduction equation has been used for modeling a diffusive nature of macroscale heat conduction by considering the energy conservation and Fourier's linear approximation of heat flux. However, it cannot accurately predict heat ... En savoir plus

Introduction: Glass relaxation occurs in a range of temperature during transition from equilibrium to super-cooled liquid. Viscoelastic material model can be applied to simulate glass behavior during the glass transition regime and to predict the glass deformation and stress evolution. ... En savoir plus

Electrocoalescence is the phenomenon of coalescence of droplets suspended in an insulating liquid or in a gas under the action of an electric field. Electrocoalescence is considered a promising tool in many petrochemical industries for desalting crude oils. However, this technique ... En savoir plus

The computation of electric field strength is the state-of-the-art technique for designing and optimizing High-Voltage (HV) equipment. In this research, the equipment under analysis is Cable Termination (CaTr) which is used to apply high-voltage (75 kV – 800 kV AC) on the cable to be ... En savoir plus

Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, ... En savoir plus

Sensors have diverse applications ranging from the medical field to space exploration. They convert physical parameters such as temperature, pressure, humidity etc. into an electrical output. The discovery of piezoresistivity property of silicon and germanium led to miniaturization of ... En savoir plus
