Preparation and Characterization Of Liquid Crystalline Compounds as Stationary Phases in Gas Chromatography

This work involves the preparation of two liquid crystalline compounds, 4,4´-bis-(4-propoxybenzylidene amino)biphenyl (2b), and 2,5-bis-[4-(4´-propoxybenzylideneamino)phenyl]1,3,4-oxadiazole (1f).The prepared compounds were characterized qualitatively by using FTIR, 1HNMR, and elemental analysis (EA).

Simulation of Neutron Activation Analysis Using Monte Carlo Method and Application for Environmental Samples

          Two neutron activation analysis systems were designed and studied. Americium-beryllium (Am-Be) was employed as a neutron source in both systems. Two different types of neutron sources (which differ in neutron flux) were used. One of them was used paraffin moderator  which was theoretically simulated using Monte Carlo method by GEANT4 package program of objective oriented programming.

Synthesis and characterization of new cross linked polymers as stationary phases for HPLC separation

Two cross linked polymers were synthesized, the first polymer was synthesized by condensation reaction between glycerol triethanol amine with maleic anhydride. The second polymer was synthesized by addition polymerization of free radical for acrylamide, bisacrylamide with ammonium persulphate and N,N,N,N-tetramethyldiamine (TEMED). The products were characterized by FTIR & X-ray. The resulted polymer have high rigidity and easily grinded, with high stability and used as stationary phase for HPLC.

Effect of Some Synthesized Urea, Thiourea and Schiff Bases Derivatives Against Proteus spp. from Urinary Tract Infections

Novel series of 14 (urea and thiourea) derivative compounds were prepared from reaction of urea and thiourea with aromatic amine compounds (homocyclic and heterocyclic), in addition to preparation of 6 Schiff bases (C=N) compounds that were prepared from reaction of some derived compounds with benzyldehyde in this study. All the 20 prepared compounds were characterized according to F.T.I.R.

A Study of Relationship between Leptin with Estradiol, Antioxidants (Selenium and Vitamin E) in the Polycystic Ovary Syndrome Patients

Objective: Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of reproductive women.  It is affecting from 5-10% of women in reproduction age. The symptoms include infertility, hirsutism and acne, menstrual abnormalities, Obesity and may cause endometrial cancer, cardiovascular disorder and diabetes mellitus.   Leptin, the product of the ob gene, is a small peptide molecule synthesized by white adipose tissues with an important role in the regulation of fat body and food intake.

Laplace Transform Method for Solving Ordinary Fractional Order Differential Equations with Constant Coefficients

Fractional Calculus is a branch of mathematical analysis that satisfies the possibility of considering the power of the differential operator as a real number. Several different families of fractional derivatives (such as,Riemann–Liouville, Caputo, Hadamard and others) are developed.In this work, we are investigate the applications of the Laplace transform to construct the solution of homogenous and nonhomogeneous
