Ghada A. Al-HamdanyGhada A. Al-Hamdany, Khalid M. Dawod,
Graphics analysis, components of genetic variation and heritability, for the characters: plant height, number of vegetative branches, number of fruiting branches, number of bolls per plant, boll...
Direct Determination of Sulfacetamide Sodium by Derivative UV Spectrophotometry
Isam J. Al-Nuri, Israa’ A. Al-Obaydi
UV Derivative spectra were used for the direct quantitative determination of sulfacetamide sodium in distilled water. The quantification was accomplished using the integrated area under the peaks....
Spectrophotometric Determination of some Phenothiazines Using N-Chlorosuccinimide
Theia N. Al-Sabha, Saladdin M. Al-Talib,
A simple and sensitive spectrophotometric method has been developed for the determination of some phenothiazine derivatives as pure and in dosage form. The method is based on oxidation of...
Synthesis of some N-Aryl- p-Toluene Sulfonamide Compounds
Ahlam M.N. Yahya, Mohammad A. Al-Iraqi,
A number of acetylenic amine (4a-e) were synthesis from propagyl p-(p-toluene sulfonamido) benzoate (3) with secondary amines via Mannich reaction. The carbonyl isothiocynate compound (5) was...
The Effect of the Chain Sequence Distribution, Nature of Monomers and Temperature on the Electrical Conductivity of some Unsaturated Amide-Ester Copolymers
Yousif A. Shahab, ad F. Mahmood, Asaad F. Khattab,
Ten Amide-ester copolymers were synthesized, whereby the sequence distribution and the used dicarboxylic acids were varied. The electric conductivity of the copolymers are determined in the pure...
Synthesis of some Acetylenic Amines Derivatives by Mannich Reaction
Haiffaa Y. Hussin,
Some acetylenic amine derivatives containing nitrogen bases (cytosine, uracil) were synthesized through Mannich reaction which involved reaction of N-propargyl cytosine or uracil with...
Spectrophotometric Determination of Phenylephrine Hydrochloride by Coupling with Diazotized 2- Aminobenzothiazole
Noha Th. Abdul Fatah, Nabeel S. Othman,
A spectrophotometric method for determination of microgram amounts of phenylephrine-HCl(PE) has been proposed. The method is based on coupling of phenylephrine-HCl with diazotized...
Improved Synthesis of 3-(α , α-diphenyl –α- hydroxymethyl)- 4-amino 1,2,4-triazoline-5-thione and Facile Route to 3,6-Disubstituted 1,2,4-triazolo [3,4-b][1,3,4] thiadiazoles(*)
Salim J. Mohammed, Badie A. Ahmed,
The reaction of thiocarbohydrazide (1) with benzilic acid (2) at the melting temperature (160-170 C) allows an improved preparation of...
Estimation of Net Radiation in Iraq
Amal M. Banoosh, Rajaa A. Basheer, Waleed I. Al- Rijabo,
FAO-56 Model was used to estimatenet Net Radiation falling on horizontal surface in Mosul, Baghdad and Nasiriyah stations for the time series (1980-2002). Results showed that there is a sort of...
