Backgrounds and Objectives: There is a considerable notice in the use of noise barriers in recent years. Noise barriers as a control noise solution can increase the insertion loss to protect receivers. This paper presents the results of an investigation about the acoustic efficiency of primitive root sequence diffuser (PRD) on environmental single T-shape barrier.Materials and Methods: A 2D bou...

In article number 2100707, Christoph Scheurer and co-workers stabilize solid state electrolyte grains against Li dendrite nucleation growth with a nanometer thin complexion. This naturally forming encapsulating layer serves as an effective electronic barrier while being permeable for ions. Future interfacial engineering could exploit corresponding local separation of ionic flux at solid-solid i...

The aim of this research was to investigate the effects of the oral administration of Gum Arabic on haematological and some oxidative stress markers in Mugil cephalus. For this purpose 60 mullet caught in Faro Lake (Italy), were acclimatized and fed with commercial diet for 20 days prior to the start of experiment, which lasted 15 days. After acclimatization, fish were randomly divided into two...

Despite the importance of reactive oxygen species (ROS) in plant immunity, stress signaling, and development (Mori and Schroeder, 2004; Gadjev et al., 2006), the molecular identities of Ca-permeable channels responding to ROS have not been established. Here, we propose annexins as candidate channel proteins. Elevation of cytoplasmic free calcium ([Ca2+]cyt) as a regulatory step in plant immunit...

The endothelium forms a selective semi-permeable barrier controlling bidirectional transfer between blood vessel and irrigated tissues. This crucial function relies on the dynamic architecture of endothelial cell–cell junctions, and in particular, VE -cadherin-mediated contacts. VE -cadherin indeed chiefly organizes the opening and closing of the endothelial barrier, and is central in permeabil...
