New Spectrophotometric Estimation and Cloud Point Extraction of Cefdinir
...Show More Authors

A sensitive spectrophotometric method was developed for the estimation of cefdinir (CFD), a cephalosporin species. This study involves two methods, and the first method includes the preparing of azo dye by the reaction of CFD diazonium salt with 4-Tert-Butylphenol (4-TBP) and 2-Naphthol (2-NPT) in alkaline medium, which shows colored dyes measured at λmax 490 and 535 nm, respectively. Beer's law was obeyed along the concentration range of (3-100) μg.ml-1. The limits of detection were 0.246, 0.447 μg.ml-1 and molar absorptivities were 0.6129×104, 0.3361×104 L.mol-1cm-1 for (CFD-4-TBP) and (CFD-2-NPT), respectively. The second method includes preconcentration for cefdinir dyes by using cloud point extraction in the presence of Triton X-114 (10% v/v) and recording measurements using the UV-Visible technique. Cloud point extraction enables the drug to be precisely estimated under the optimal experimental conditions. The concentrations were ranged between (0.1-6.0) and (0.2-6.0) μg.ml-1. The limits of detection were 0.032, 0.054 μg.ml-1 and molar absorptivities were 0.4733×105, 0.2788×105 L.mol-1cm-1, respectively. Enrichment factors were 24.61, 24.58, and distribution coefficients were 1526, 1393 for (CFD-4-TBP), (CFD-2-NPT), respectively. The proposed methods have been applied for the determination of CFD in commercial formulation with no interference. The results appear to be no significant difference between the two methods.

Synthesis, Characterization and Preliminary Anti-inflammatory Evaluation of New Etodolac Derivatives
...Show More Authors

Three new hydrazone derivatives of Etodolac were synthesized and evaluated for their anti-inflammatory activity by using egg white induced paw edema method. All the synthesized target compounds were characterized by CHN- microanalysis, FT-IR spectroscopy, and 1HNMR analysis. The synthesis of the target (P1-P3) compounds was accomplished following multistep reaction procedures. The synthesized target compounds were found to be active in reducing paw edema thickness and their anti-inflammatory effect was comparable to that of the standard (Etodolac).

Robust estimation of multiple linear regression parameters in the presence of a problem of heterogeneity of variance and outliers values
...Show More Authors

Often times, especially in practical applications, it is difficult to obtain data that is not tainted by a problem that may be related to the inconsistency of the variance of error or any other problem that impedes the use of the usual methods represented by the method of the ordinary least squares (OLS), To find the capabilities of the features of the multiple linear models, This is why many statisticians resort to the use of estimates by immune methods Especially with the presence of outliers, as well as the problem of error Variance instability, Two methods of horsepower were adopted, they are the robust weighted least square(RWLS)& the two-step robust weighted least square method(TSRWLS), and their performance was verifie
