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
Shiranish formation has been divided into two microfacies units: 1 - Many biowackestone facies and 2 - maly packstone using planktonic foraminifera and other carbonate components in the rock cutting and core slides. Microfacies reflect marin deep shelf margin in the lower part of the formation, the upper part was deeper. The thickness of the formation is determined, depending on addition to the presence of echinoderm framents debris and spines. This is in disagreement with the 195 ft thickness reported by the Oil Exploration Company The age of the formation is estimated depending on the recognized biostratigraphic zone using the index fossils to be Upper - Middle Mastrichtion.
The present research included synthesis of silver nanoparticle from(1*10-3,1*10-4 and1*10-5) M aqueous AgNO3 solution through the extract of M.parviflora reducing agent. In the process of synthesizing silver nanoparticles we detected a rapid reduction of silver ions leading to the formation of stable crystalline silver nanoparticles in the solution.

One of the most important parameters determining structural members' durability and strength is the fire flame's influence and hazard. Some engineers have advocated using advanced analytical models to predict fire spread impact within a compartment and considering finite element models of structural components to estimate the temperatures within a component using heat transfer analysis. This paper presented a numerical simulation for a reinforced concrete beam’s structural response in a case containing Water Absorbing Polymer Spheres (WAPS) subjected to fire flame effect. The commercial finite element package ABAQUS was considered. The relevant geometrical and material parameters of the reinforced concrete beam model a

Fullerene nanotube was synthesized in this research by pyrolysis of plastic waste Polypropylene (PP) at 1000 ° C for two hours in a closed reactor made from stainless steel using molybdenum oxide (MoO3) as a catalyst and nitrogen gas. The resultant carbon was purified and characterized by energy dispersive X-ray spectroscopy (EDX), X-ray powder diffraction (XRD). The surface characteristics of C60 nanotubes were observed with the Field emission scanning electron microscopy (FESEM). The carbon is evenly spread and has the highest concentration from SEM-EDX characterization. The result of XRD and FESEM shows that C60 nanotubes are present in Nano figures, synthesized at 1000 ° C and with pyrolysis tempera

A developed model has been put for the hypothesis of capturing moons in explaining the origin of Jupiter moons, and study the change of the orbital properties of these satellites as well as the distance from the planet. Jupiter moons were divided into two types according to their physical and orbital properties, they are the moons , which are formed from the same material as the planet, so it was named the original moons ,while the moons that have been captured from the surrounding space was renamed exotic moons . And the moons of exotic origin asteroid belt and the Kuiper belt in the region which is behind Neptune, the origin of each clique of moons is an asteroid fragmented after colliding previously with another body and
