Wind Effect on Single-Column Support Billboard [PDF]

Iranica Journal of Energy and Environment
Billboards are one of the types of structures that wind load can be the dominant lateral load on this type of structures. Since billboards are usually placed in public places, destroying these structures under wind can cause irreparable damage.

Pressure‐Assisted Drug Delivery Using High‐Pressure Balloon Platform Improves Vascular Drug Penetration and Anti‐Restenotic Effects

Advanced Healthcare Materials, EarlyView.
A dual‐layer high‐pressure drug‐coated balloon (HP@DCB) increased balloon‐wall contact and promoted deeper paclitaxel (PTX) penetration than a conventional noncompliant DCB. In in vivo study, HP@DCB treatment improved luminal patency and reduced neointimal hyperplasia, supporting pressure‐assisted drug delivery as a promising strategy for enhancing the

A CFD Model for Biomass Flame-Combustion Analysis [PDF]

Chemical Engineering Transactions, 2016
The present work addresses the study of the combustion of individual biomass particle surrounded by a gas stream of N2/O2 under the operating conditions encountered in a drop tube reactor. The aim of this analysis is to give a better insight into the chemical and physical processes that occur both at particle and reactor scale where the volatiles ...
