In this work we have developed and characterized a novel fabrication process for producing dense, porous array of silica particles packed inside a plastic microfluidic channel. The novel approach relies on in-situ crystallization of colloidal silica particles within specific regions of a microchannel defined by plasma processing. These selfassembled silica colloids through a plastic microchanne...

Abstract Aiming at the problems of large cross-section size change and low shape position accuracy workpiece rolled by four-power rolling mill, based on analyzing plastic deformation mechanism metal crystals, simulation was carried out deform software to analyze variation section height equivalent stress distribution section. The results show that under action mutual vertical force, with a leng...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

Connections with Reduced Beam Section (RBS) have been investigated in the last 20 years both from an analytical point of view and from an experimental point of view. Several experimental tests demonstrated that RBS connections designed according to themost modern seismic codes are able to obtain the desired goal: the protection of the connection due to the yielding of the adjacent RBS. But in a...

The annual American Society of Plastic Surgeons’ “Plastic Surgery: The Meeting” is always filled with great educational events and endeavors, and the 2015 gathering in Boston was truly exceptional. Perhaps the most memorable and most rewarding panel that we had the honor and pleasure to be a part of was the Medical Student Session, moderated by one of the first Plastic and Reconstructive Surger...

Background A literature review did not reveal any study investigating the prevalence of depression among plastic surgery residents. Methods We conducted a cross-sectional mail survey and included all Saudi Plastic Surgery residents in our local program in Saudi Arabia. The Beck Depression Inventory II was used. Results The inventory showed that mild, moderate, and severe depressive symptoms...

Aesthetic plastic surgery is a branch of medicine using surgical techniques to alter the appearance of patients. In this paper it is considered whether aesthetic plastic surgery should be viewed as an art form. The question is answered by trying to see how aesthetic plastic surgery fits a number of classical concepts in philosophical aesthetics, concepts such as “artist” and “work of art”. Furt...
