Compound <strong><em>1</em></strong> &amp; <strong><em>2</em></strong> were crystallized in monoclinic system with the space group P2(1)/n and P2(1)/c, respectively. The interaction effects of two α-aminophosphonate derivatives (<em>1</em> &amp; <em>2</em>) with BSA were investigated and the binding constants were 1.07 × 10<sup>4</sup> M<sup>-1</sup>, 1.68 × 10<sup>4</sup> M<sup>-1</sup>, respectively. Besides, the values of n were indicated that 1:1 complex was formed between BSA and 1&amp;2.</p> 2019-11-12T00:00:00+00:00 ##submission.copyrightStatement## http://www.journalcsij.com/index.php/CSIJ/article/view/30139 Investigation of Selected Heavy Metals Concentration in Animal Feeds in United Arab Emirates 2019-11-14T06:24:27+00:00 Nizar A.

Al Jeaidi <p>The animal feed materials contaminated with heavy metals, which usually comes from soils to plant, atmosphere and contaminated seawater. Various animal feed and feed supplements imported by local agents at United Arab Emirates (UAE) subjected for analysis using ICP- MS technique the concentration of the four selected heavy metals, namely; Arsenic (As), Lead (Pb), Cadmium (Cd), and mercury (Hg), found to be within the national standard.</p> 2019-11-13T00:00:00+00:00 ##submission.copyrightStatement##
