Long fibers of bone-like hydroxyapatite/collagen nanocomposites were fabricated via a self-organization under biomimetic conditions in order to obtain much more suitable biomechanical and biochemical properties for artificial bone and tissue engineering scaffolds. The fiber growth was controlled with ionic strength in the reaction vessel and was explained by a crystal growth model. The composit...

Assessment of likely consequences of a potential accident is a major concern for loss prevention and safety promotion in process industry. Loss of confinement on a storage tank, vessel or piping on industrial sites could imply atmospheric dispersion of toxic or flammable gases. Gas dispersion forecasting is a difficult task since turbulence modeling at large scale involves expensive calculation...

A well-functioning vascular access remains the lifeline for patients with end-stage renal failure, who are being treated by chronic haemodialysis. Since 1966, the radiocephalic arteriovenous (AV) fistula, initially described by Brescia and Cimino, has been employed as a vascular access in many dialysis patients [1]. The Brescia-Cimino AV fistula has a low rate of complications and a high patenc...

Planing vessels usually have low ratios of resistance to weight, so they can move fast on sea surface than the displacement or semi-displacement ships. Access to higher speeds is one of the attractions for designers and users. To achieve higher speeds, reducing the hydrodynamic resistance is a necessity for this class of vessels. In this study, a 3D finite volume approach is used to analyze the...

This paper proposes a biometric system for authentication that uses the retina blood vessel pattern. The retina biometric analyzes the layer of blood vessels located at the back of the eye. The blood vessels at the back of the eye have a unique pattern, from eye to eye and person to person. The retina, a layer of blood vessels located at the back of the eye, forms an identity card for the indiv...

Direct detection and analysis of biomolecules and cells in physiological microenvironment is urgently needed for fast evaluation of biology and pharmacy. The past several years have witnessed remarkable development opportunities in vitro organs and tissues models with multiple functions based on microfluidic devices, termed as "organ-on-a-chip". Briefly speaking, it is a promising technology in...
