Using natural hemp fibers to reinforce the tensile characteristics of polymer matrix composites is investigated in this article. The fibers were applied to the epoxy matrix in unidirectional and hybrid tissue forms. After preparation of standard tensile stress test specimens via manual layup, the standard tensile test was done.  Young’s modulus, ultimate tensile stress, and the amount of absorb...

Unidirectional electromagnetic modes have significant potential for routing radiation and are highly desirable various applications, such as isolators, splitters, switches. In this study, we theoretically investigate surface magnetoplasmons (SMPs) in a four-layer structure consisting of perfect magnetic conductor (PMC)–semiconductor–dielectric–metal, which exhibits complete unidirectional propa...

The reactivation of inherited tectonic structures formed during the Paleoproterozoic Trans-Hudson Orogeny (THO) has played a significant role in generating high-grade unconformity-related uranium deposits eastern Athabasca Basin. these is now investigated through series two-dimensional hydrothermal numerical models. Two modelling scenarios are considered: (1) models THO peak metamorphism and (2...

Exchange bias is a unidirectional magnetic anisotropy that often arise from interfacial interaction of ferromagnetic and antiferromagnetic layers. In this article, we show metallic layer with spin-orbit coupling can induces an exchange via interface magnetoelectric effect. linear response regime, the effect induced by couplings arises broken symmetry system. Furthermore, demonstrate be controll...

The study is related to the formulation and evaluation of mucoadhesive buccal tablets Anastrozole enhance its bioavailability by avoiding 1st pass effect. succeeded in developing containing two layers (mucoadhesive backing layer) a design that permits unidirectional release drug. Tablets were prepared double direct compression method using (carbopol 934) as primary polymer, Sod.alginate, Na CMC...

There is growing interest in providing multimedia and broadband access over satellites. However there are several technical challenges need to be addressed. One challenge is security in terms of understanding threats and providing an effective security system. Also this paper presents a ULE security solution using ULE mandatory extension headers. The design issues and choices are discussed. The...

This paper describes new concepts the author has proposed and demonstrated to realize metal and polymer based sensitive and/or active structural material systems suitable for smart structures. Most of the developments have been done by simple and innovative methods without using sophisticated and expensive sensors and actuators. The following topics are mainly examined: (1) forming optical inte...

Malfunction of the unidirectional valve in a breathing circuit system may cause hypercapnia from the rebreathing of expired gas, ventilation failure, and barotrauma. Capnography is a useful method for monitoring the integrity of the unidirectional valve. We experienced two cases of malfunction of a unidirectional valve which caused leakage and reverse flow, diagnosed early as a change of the ca...
