fenpropathrin is a new pyrethroid insecticide used to control crop pests. the aim of this study was to evidence fenpropathrin-induced oxidative stress and alterations in biochemical parameters in the freshwater fish, alburnus mossulensi s. total antioxidant capacity, malondialdehyde (mda), catalase activity (cat), aspartate aminotransferase (ast), alanine aminotransferase (alt), alkaline phosph...

A dominating coloring by k colors is a proper k coloring where every color i has a representative vertex xi adjacent to at least one vertex in each of the other classes. The b-chromatic number, b(G), of a graph G is the largest integer k such that G admits a dominating coloring by k colors. A graph G = (V,E) is said b-monotonous if b(H1) ≥ b(H2) for every induced subgraph H1 of G and every subg...

Understanding the stability limitations and defect formation mechanisms in 2D magnets is essential for their utilization spintronic memory technologies. Here, we correlate defects mono- to multilayer CrSBr with structural, vibrational magnetic properties. We use resonant Raman scattering reveal distinct signatures. In pristine CrSBr, show that bromine atoms mediate interlayer coupling, allowing...

Inscription of embedded photoluminescent microbits inside micromechanically positioned bulk natural diamond, LiF and CaF2 crystals was performed in sub-filamentation (geometrical focusing) regime by 525 nm 0.2 ps laser pulses focused 0.65 NA micro-objective as a function pulse energy, exposure inter-layer separation. The resulting were visualized 3D-scanning confocal Raman/photoluminescence mic...

This paper is the first microscopic observation of entire cracking process in delayed fracture high-strength steel bolt after long-term atmospheric exposure. A sufficiently fresh surface exhibits initiation propagating crack a thin zone beneath screw groove, resulting from merging multiple cracks nucleated therein. The morphology initially intergranular, exhibiting three-dimensional shape prior...

Noise induced hearing loss (NIHL) is one of the most important occupational disease worldwide. NIHL has been found potentiate by simultaneous carbon monoxide (CO) exposure. Free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the CO hypoxia. This study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

Let F be a class of finite groups, p a prime and π a set of some primes. A finite group G is called a p-quasi-F-group (respectively, by π-quasi-F-group) provided that for every F-eccentric G-chief factor H/K of order divisible by p (respectively, by at least one prime in π), the automorphisms of H/K induced by all elements of G are inner. In this paper, we obtain the characterizations of p-quas...

The present study was planned to investigate the efficiency of explicit teaching and adequacy of the L2 learners' exposure to L2 input in academic contexts in Iran. The case at hand was the acquisition of referential, quasi and expletive subject pronouns, as three different types of obligatory subjects in English. 96 Iranian EFL learners were selected from two universities in Isfahan. They were...
