AuNPs are being conventionally synthesized by traditional methods (physical and/or chemical) with preferred and well-defined morphology, size shape. On the other hand, it has been reported that these involve difficult reaction conditions toxic chemicals. In this study, an easy, cost effective more environmentally biological-friendly method was described for synthesis of gold nanoparticles Dimri...

Attempts were made to test the validity of the general view that inferotemporal lesions in monkeys do not result in a visual acuity disorder. It was found in the first experiment that monkeys with total removal of the inferotemporal visual area (TIT monkeys) showed a significant elevation of the discrimination limen for visual patterns of reduced sizes even when compared to monkeys with removal...

Pierce’s disease (PD) causes symptoms of leaf scorch and fruit cluster wilt on wine, table and raisin grapes, and is caused by the bacterial pathogen Xylella fastidiosa. These fastidious, gram-negative bacteria occur only in the xylem of infected plants and are transmitted by xylem-feeding insects; leafhoppers and sharpshooters. The close association of plants with bacteria, either pathogenic o...

Dissolved organic carbon (DOC) is critically important in the chemistry of freshwater. It complexes heavy metals, making them less bioavailable to aquatic organisms, and absorbs and attenuates UVB radiation, undergoing degradation and alteration in the process. This study examined changes in metal toxicity to the freshwater green alga Pseudokirchneriella subcapitata in high- and low-DOC natural...

Advanced micrometeorological methods have become increasingly important in soil, crop, and environmental sciences. For many scientists without formal training in atmospheric science, these techniques are relatively inaccessible. Surface renewal and other flux measurement methods require an understanding of boundary layer meteorology and extensive training in instrumentation and multiple data ma...
