mapping based on total concentrations of micronutrients may be useful in fertility management including fertilizer and/or wastewater application. the aims of this work were to (1) investigate the spatial distribution of total concentrations of copper (cu), zinc (zn), manganese (mn) and iron (fe); (2) to select the suitable spatial estimator; and (3) to understand the effect of wastewater irriga...

ABSTRACT Soil erosion is one of the fundamental issues in the fields of environmental , natural resources and agriculture. And today know this topics and related issues that should be considered to take over. using Of new method Instead of traditional methods in order understanding and applying appropriate planning is essential. The aim of this study review Erodibility and Boir Ahmad province u...

in this work‎, ‎we formulate chatterjea contractions using graphs in metric spaces endowed with a graph ‎‎and‏ ‎‎‎‎investigate ‎the ‎existence‎ ‎of ‎fixed ‎points ‎for such mappings ‎under two different hypotheses‎. we also discuss the uniqueness of the fixed point. the given result is a generalization of chatterjea's fixed point theorem from metric spaces to metric spaces endowed with a graph.

Background and Aim: Rabies, a viral and zoonotic disease, causes acute and fetal encephalitis in humans and other mammals and is a cause of death in developing countries. It is usually transmitted by animal bite, but other routes of transmission are mucus membranes, breathing, placenta, contaminated instruments, and organ implanting. This study shows the mapping of geographical distribution of ...
