Currently, there is a great interest in the study of gels, especially their transport or release properties. Hydrogels have countless definitions, but generally speaking, they are hydrophilic systems with a three-dimensional structure that tend to swell and hold large amounts of water ... En savoir plus

Valves are widely used to control fluid flow in various engineering applications. It’s crucial to study the flow characteristics inside the valve and the fluid-structure interaction between the fluid and valve’s sleeve for design, optimization and improvement of valves. However, because ... En savoir plus

Transdermal drug delivery is an emerging mechanism for continuous systematic solutions in medical healthcare problem. Transdermal drug delivery has significant advantages when compared to conventional methods such as oral administration or intramuscular injection. Most of the ... En savoir plus

This work is focused on the development of a physical-mathematical model capable of predicting the temperature and water content fields within a pasta sample which is exposed to a stream of drying air flowing under turbulent conditions. Therefore, the equations concerning the transfer of ... En savoir plus

The paper attempts to give a contribution to the dynamic analysis of musical instruments. A multidisciplinary approach oriented to the study of mechanical, structural, vibratory and acoustical phenomena related to stringed instruments is discussed. The case study focused in this paper ...

Macroscopic modeling of fluid flow and thermal diffusion, in a porous medium, requires the description of equivalent properties (permeability, conductivity and diffusivity). However, depending on the microstructure topology of the porous medium and the fluid flow regime at the ... En savoir plus

Microbubble oscillations in the presence of ultrasound wave inside blood vessel have been widely studied for therapeutic applications like drug and gene delivery[1], blood-brain barrier opening[2], and lysis of blood clot[3] and cell membrane[4]. An oscillating bubble exerts stresses on ... En savoir plus

Solenoid valves control fluid flow by using the passage of an electric current to produce a magnetic field that controls the displacement of a pre-tensioned plunger. As the electric current increases, the induced force causes the plunger to move upward against the force exerted by a ... En savoir plus

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... En savoir plus
