Research has been designed to focusing and evaluation the effect of cypermethrin as insecticide material in the skin of the rabbits. Cypermethrin was applied on the skin after shaving the dorso-lateral aspect of rabbits .The animals (12) were classified into four groups (A, B, C and D), three animals per group. Groups (B, C and D) were exposed to cypermethrin at doses (0.001, 0.005, 0.010)mg/kg respectively, while (A) was a control group. After ten days of drug's application, animals of group (D) were died at ending of the study because they received heavy dose. The groups (B and C) shown excitation signs, followed by inhibition and depression of their activity. The animals of groups (A, B and C) were scarified and a specimens (0.5) cm3 of skin from the dorso- lateral aspect were obtained, washed with water and put in formalin (10)% then processed after (24) hours by using histological technique, sectioned at (5)µm thickness, stained with Hematoxylin and Eosin a then examined under light microscopic at different powers.

Authors: Hather Ibraheem Abed  
Published: April 2023

Image segmentation is an important process in image processing. Though, there are many applications are affected by the segmentation methods and algorithms, unfortunately, not one technique, but the threshold is the popular one. Threshold technique can be categorized into two ways either simple threshold which has one threshold or multi- thresholds separated which has more than two thresholds . In this paper, image segmentation is used simple threshold method which is a simple and effective technique. Therefore, to calculate the value of threshold solution which is led to increase exponentially threshold that gives multi-thresholds image segmentation present a huge challenge. This paper is considered the multi-thresholds segmentation model for the optimization problem in order to overcome the problem of excessive calculation. The objective of this paper proposed an slgorithmto solve the optimization problem and realize multi-thresholds image segmentation. The proposed multi-thresholds segmentation algorithm should be segmented the raw image into pieces, and compared with other algorithms results. The experimental results that show multi-thresholds image segmentation based on backtracking search optimization algorithm are feasible and have a good segmentation.

A total of 18 surface soil samples were collected from surrounding of industrial district at north Baiji town, and the concentration of seven trace elements (i.e. Cu, Pb, Zn, Ni, As, Cd and Cr) were analyzed. The geo-accumulation index, pollution index, Nemerow pollution index, ecological risk factor and potential ecological risk index were utilized to assess soil contamination by trace elements. The mean values of geo-accumulation index showed that the study area soils are ranged from moderate to heavy contamination by Ni and slight contamination by As, Cd and Cr and uncontaminated by Zn, Pb and Cu. According to categories of pollution index, the surface soil of study area considers strongly polluted by Ni, moderately polluted by Cr and non-polluted by Cu, Zn, As, Pb and Cd. The Nemerow pollution index values of study area showed 11% of sites are slightly polluted, 17% of sites are moderately polluted and 72% of sites are seriously polluted. According to Eco- risk factor for an individual metal, the values showed moderate to considerable ecological risk by Cd, low to moderate ecological risk by Ni and low ecological risk for Cu, Zn, As, Pb and Cr. For Eco-risk index for metals, the results also showed that 27.8% of sites are low potential ecological risk and 72.2% of sites are moderate potential ecological risk

Published: April 2023

A rapid, simple, accurate, and economized spectrophotometric method for the determination of salbutamol sulfate(SAL) has been suggest using an oxidation-reduction reaction. This method depends on the oxidation of SAL medication with an excess amount of chromate (CrO42- ) as an oxidant agent in the acidic medium of 2N Sulphuric acid and the presence of Sodium oxalate as a catalyst of the oxidation process. Then the remaining quantity of chromate will be reacted with 1,5-diphenylcarbazide to form a pink-reddish and stable water-soluble complex which is exhibiting maximum absorption at 543 nanometers. The optimum conditions for the present work were studied experimentally. The linearity of the proposed method follows Beer’s law in the concentration range of 50 to 900 μg in a final volume of 25ml with a molar absorptivity which is equal to 0.538×104 l.mol-1.cm-1. The proposed method shows good recovery values, accuracy, and precision. The present method was so good to be successfully applied for the determination of SAL medication in its pure form and pharmaceutical preparations.
