Isolation and Identification of Wide-Spectrum Antifungal Bacteria
Omar M. Al-Obaidy
A type of bacteria was isolated from garden soils (rhizosphere soils of some garden plants) that showed a great antagonistic activities toward different phytopathogenic and even human and...
Measurement of Glutamate-Oxalacetate Transaminase Activity in Human Blood Serum Using Differential Pulse Anodic Stripping Voltammetry
Ramiz S. Alkasir, Haitham A. Al-Wahab, Saadallah T. Sulaiman
A new electrochemical method for measuring the activity of glutamate-oxalacetate transaminase (GOT) in human blood serum was developed based on the appearance of a voltammetric peak current of...
Synthesis and Cyclization of some N-(2-Pyridyl) Anthranilic Acids
Azam A. AL-Hadedi, Rafid K. Jameel
A series of N-(2-Pyridyl) anthranilic acids (Ia-f) have been synthesized by Ullmann reaction. Cyclization of (Ib,d,f) by phosphorusoxy chloride (POCl3) gives substituted 5-chlorobenzo [b][1,8]...
Synthesis of Five Membered Heterocycles Using Microwaves Technique
Moayed S. AL. Gawady
A series of N-(5-substituted 1,3,4thiadiazol-2-yl maleimides (14-18) were prepared by cyclization of corresponding maleamic acids (7-12).These acids were prepared by the reaction of...
Synthesis of some Fused Heterocyclic Compounds from α-Bromo Tetralone and Indanone
Akram N. Mohammad, Ahlam M.N. Yahya
A number of heterocyclic compounds (7-14) were prepared by the reaction of -bromo ketones (3,4) with 2-amino-5-phenyl-1,3,4(thiadiazole or oxadiazole) and 5-phenyl-1,3,4-triazole-2-thiol....
Spectrophotometric Determination of Vitamin B6 by Coupling with Diazotized p-Nitroaniline
Asma N. Abdul Kadir
A spectrophotometric method has been described for the determination of pyridoxine hydrochloride (vitamin B6) in pure and pharmaceutical preparations. The method is based on coupling reaction of...
Determination of Catechol Using Flow Injection -Electrochemical Detection with Banana Paste Electrode: Application to Adrenaline Determination
Yousra M. Al. Shaker, Amer T. Al-Taee, Wadala A. Bashir
This work involves indirect determination of catechol compounds using flow-injection electrochemical detector. The detector based on the three-electrodes system, banana paste [which contained the...
A New Approach for Evaluation of the Hubble and the Deceleration Parameters
Aziz J. Abdel-Kadder, Nazzeha A. Daod, Mohammed K. Zeki
In this work we studied the dependence of the Cosmological parameters (the Hubble H(t) and deceleration q(t) parameters) on the red shift through the scale factor R(t), so we obtained two relations...
