In support of improved personal armour development, depth of penetration tests have been conducted on four different ceramic materials including alumina, modified alumina, silicon carbide and boron carbide.These experiments consisted of impacting ceramic click here tiles bonded to aluminum cylinders with 0.50 caliber armour piercing projectiles.The
In this article, a broadband 3-dB directional coupler is proposed using groove gap waveguide (GGW) structures.Gap waveguide stuart products emcelle tocopherol technology has been introduced to overcome manufacturing and assembling challenges of different millimeter-wave components and devices.The presented coupler has wideband coupling flatness wit
The widespread growth of the Internet-of-Things (IoT) and its dependence on the license-exempt Industrial, Scientific, and Medical (ISM) bands have made spectrum resources scarce.IoT can nonetheless get advantage from the Cognitive Radio (CR) technology to resolve the spectrum shortage issue.Since in CR networks the unlicensed Secondary Users (SUs)
Methylation of specific lysine residues in core histone proteins is essential for embryonic development and can impart active and inactive epigenetic marks on chromatin domains.The ubiquitous nuclear protein PTIP is encoded by the Paxip1 gene and is an essential component of a histone H3 lysine 4 (H3K4) methyltransferase complex conserved in metazo
Over the years, the growing interest for bio-based alternatives to mineral products (i.e.fuel and lubricant) to save energy and 9x11 pergola improve environmental friendliness has become one of the most researched topics.According to world meteorological organization (WMO), Concentration of carbon dioxide (CO2) reached 420.23 parts per million in A
