The 3-aminoacetophenone and 4-aminoantipyrine were used as precursors to prepare new six ligands. The three new ligands (L1,L2 and L3) were synthesis by reacting one mole of 3-aminoacetophenone with one mole of (Acetyl chloride), (benzoyl chloride), (4-methoxybenzoyl chloride) and ammonium thiocyanat in acetone as a solvent, they are:- L1 (AAA) =[N-(3-acetylphenylcarbamothioyl)acetamide] L2 (BAA) =[N-(3-acetylphenylcarbamothioyl)benzamide] L3 (MAA) =[N-(3-acetylphenylcarbamothioyl)-4-methoxy benzamide] Also three new derivatives of 4-aminoantipyrine were synthesis by reacting one mole of 4-aminoantipyrine with one mole of (Acetyl chloride), (benzoyl chloride), (4-methoxybenzoyl chloride) and ammonium thiocyanat in acetone as solvent and the ligands are given: L4 (AAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)acetamide] L5 (BAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)benzamide] L6 (MAD) =[N-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-ylcarbamothioyl)-4-methoxybenzamide] These ligands were identified by FT-IR ,1H,13C-NMR,elemental analysis(C.H.N.S), electronic spectra, the molecular formula of there were concluded:- L1 (AAA) = C11H12O2N2S L2 (BAA) = C16H14O2N2S L3 (MAA) = C17H16O3N2S L4 (AAD) = C14H16N4O2S L5 (BAD) = C19H18O2N4S L6 (MAD) = C20H20O3N4S The ligands were reacted with some metal ions (M+2 =VO, Mn, Co, Ni, Cu, Zn, Cd , Hg and Pd), to give complexes with molecular formulas:- [M(AAA)2(H2O)2]Cl2 , [M(BAA)2(H2O)2]Cl2 , [M(MAA)2(H2O)2]Cl2, [M(AAD)2(H2O)2]Cl2 , [M(BAD)2(H2O)2]Cl2, [M(MAD)2(H2O)2]Cl2 Where (M+2 = Mn, Co, Ni, Cu, Zn, Cd , Hg and Pd) [VO(AAA)2]SO4 , [VO(BAA)2]SO4 , [VO(MAA)2]SO4, [VO(AAD)2]SO4 , [VO(BAD)2]SO4, [VO(MAD)2]SO4 The complexes were characterized by solubility, melting point and decomposition, FT-IR, electronic spectra, molar conductivity, magnetic susceptibility measurements, element microanalysis for some complexes and flame atomic absorption. From above results, one can conclude that complexes of (M+2 = Mn, Co, Ni, Cu, Zn, Cd, Hg and Pd) have an octahedral geometry while the square pyramid for complexes for(VO+2) The biological effects of ligands and some of their complexes have been investigated on two types of bacteria species Staphylococcus aureu a gram positive and Escherichia coli a gram negative In agricultural agar medium, the results exhibited all the compounds (expect Ni2+ with L1)have varsity anti bacterial activities
The leaves and stems of the local Purslane plant ( Portulaca oleracea oleracea L. ) were used to preapare the extract of two types ( wet and dried extractions) the extracts were prepared by weighting of 60grams of the wet and the dried plant individually, then boiled in 500ml of distal water. Finally the volume was completed to1 liter, then we used these extracts to prepare of 8 types of the culture media contained basic, selective and enrichment media for growing a group of pathogenic bacteria. 8 types of bacteria were used for this purpose: Escherichia coli, Pseudomonas flouresence, Staphylococcus aureus , Staphylococcus epidermidis, Bacillus subtilis , Klebsiella pneumoniae , Proteus mirabilis and Proteus vulgaris.

Background: This study was conducted to evaluate the hard palate bone density and thickness during 3rd and 4th decades and their relationships with body mass index (BMI) and compositions, to allow more accurate mini-implant placement. Materials and method: Computed tomographic (CT) images were obtained for 60 patients (30 males and 30 females) with age range 20-39 years. The hard palate bone density and thickness were measured at 20 sites at the intersection of five anterioposterior and four mediolateral reference lines with 6 and 3 mm intervals from incisive foramen and mid-palatal suture respectively. Diagnostic scale operates according to the bioelectric impedance analysis principle was used to measure body weight; percentages of body fa

Volumetric chemical adsorption was done in a volumetric apparatus using hydrogen gas at room temperature on eleven platinum catalyst, commercial catalysts (RG-412,RG-402 ,RG-432, RG-451, RG-482, and PS-10) and prepared platinum catalysts with 0.1, 0.2 , 0.45 , and 0.55% by weight of Pt supported with Y-alumina. The results show that the metal crystallite area increases with increasing platinum content. The dispersion and particle size of metal crystallite located between 48.2-96.1% and 3.85-12.72 nm, respectively. For bimetallic catalysts, the hydrogen intake decrease in the following order : Re < Sn < Ir.

In this paper, a new seven-parameter Mittag-Leffler function of a single com-plex variable is proposed as a generalization of the standard Mittag-Leffler function, certain generalizations of Mittag-Leffler function, hypergeometric function and confluent hypergeometric function. Certain essential analytic properties are mainly discussed, such as radius of convergence, order, type, differentiation, Mellin-Barnes integral representation and Euler transform in the complex plane. Its relation to Fox-Wright function and H-function is also developed.

Cancer stay to be one of the leading causes of death throughout the world due to a limited success to use treatments. The new synthesized metal complexes with formula: [Ni L2 (H2O)2]. 2.5 E t OH and [Cd L2]. ½ H2O Where L = Bis [ 5 – ( P – nitrophenyl ) - 4 – phenyl 1 , 2 , 4 – trazol – 3 – dithiocarbamato hydrazide ] and the aqueous extract of Teucrium polium L.(TP) plant (Ja,adahin Arabic) were examined against growth cells of hepatocellular Carcinoma cell Line ( HeP2 ). The cytotoxicity assay of cancer cell line was used for determination of inhibition rate with three concentrations; (62.5, 105 and 250 µg /200µl). The aqueous extract of TP plant induced death of cancer cells by significant elevation of the inhib
