High-resolution organic carbon isotope ( ? 13 C), Hg concentration and isotopes curves are presented for the Permian-Triassic boundary (PTB) sections at Guryul Ravine (India) Meishan D (China). The total (TOC)-normalized concentrations reveal more intense environmental changes Latest Permian Mass Extinction (LPME) earliest Triassic (ETME) horizons coinciding with major C shifts. To highlight pa...
The present study was conducted to find the effect of three heavy metals, Ag, Hg and Pb on the expression level of a gene encoding plasma membrane H+-ATPase in Aeluropus littoralis. The experiment was laid out in a completely random design with three replications. The expression of the main gene was normalized to the expression of the housekeeping gene actin. Two 259 and 187 bp fragments were a...
Introduction: Exposure to mercury (Hg) by consumption of fish is a recent health concern. So, it is important to evaluate the health risks related to canned fish consumption. The purpose of this study was to investigate the potential health risk based on Hg concentration in people who consumed canned fish with a probabilistic approach in Isfahan City, the central province in Iran. Materials an...
This paper analytically and numerically investigates misalignment mode-mismatch induced power coupling coefficients losses as a function of Hermite Gauss (HG) mode order. We show that higher-order HG modes are more susceptible to beam perturbations when, for example, into optical cavities: the mode-mismatch-induced scale linearly quadratically with respect indices respectively. As result, toler...
