in the past 25 years, rising of the caspian sea level, part of a natural treat to the sea, has inundated and destroyed many buildings and arable lands and threatened many inhabitations in coastal areas. the main reason for these damages is that the law-setback has lost its efficiency and human activities have proceeded seaward. the goal of this study is to introduce a proper setback line for th...

Kresoxim-methyl is nowadays widely used to combat a diversity of common diseases affecting high-value crops. In this article, we report the development and characterization of two novel immunoassays for the analysis of this pioneer strobilurin fungicide, and for the first time, a validation study with food samples was performed. A direct and an indirect competitive immunoassay based on a new an...

Abstract This work aims to introduce a simple high-performance sensitive electrochemical sensor of reformed carbon paste (CP) with iron oxide nanoparticles (IONs). It was developed determine one the most important drugs called vitamin B 6 in medium phosphate buffer (PBS) over pH ranging from 5.0 8.0. The and surface characterization achieved by different techniques comprising impedance spectros...

Communities looking to improve fire protection may consider incorporating landscape features that ‘buffer’ the effects of a between developed and undeveloped lands. While landscapes such as golf courses, vineyards, or agriculture are already being considered part this buffer zone, few empirical studies demonstrate causally how well these different operate buffer. This research selects courses a...

Feedback regulation in biochemical systems is fundamental to homeostasis, with failure causing disease or death. Recent work has found that cooperation between feedback and buffering—the use of reservoirs of molecules to maintain molecular concentrations—is often critical for biochemical regulation, and that buffering can act as a derivative or lead controller. However, buffering differs from d...

‎We firstly prove the completeness of the category of crossed modules in a modified category of interest‎. ‎Afterwards‎, ‎we define pullback crossed modules and pullback cat objects that are both obtained by pullback diagrams with extra structures on certain arrows‎. ‎These constructions unify many corresponding results for the cases of groups‎, ‎commutative algebras and can also be adapted to ...

A rapid, specific, and reproducible high-pressure liquid chromatographic method was developed for the determination of cefoperazone concentration in serum and tissue. The assay uses a simple methanol extraction, with cefoxitin as the internal standard. The limits of detection are 1 to 150 micrograms/ml; the maximum coefficient of variation is 7.4%. Using the same chromatography column, muBondap...
