The ligand 4-amino-N-(5-methylisoxazole-3-yl)-benzene-sulfonamide(L1) (as a chelating ligand) was treated with Pd(II),Pt (IV) and Au(III) ions in alcoholic medium in order to prepare a series of new metal complexes. Mixed ligand complexes of this primary ligand were prepared in alcoholic medium in presence of the co-ligand 4,4'-dimethyl-2,2'-bipyridyl(L2) with Cu(II) ,Pd(II) and Au(III) ions. The complexes were characterized in solid state using flame atomic absorption, elemental analysis C.H.N.S, FT-IR, UV-Vis Spectroscopy, conductivity and magnetic susceptibility measurements. The nature of some complexes formed in ethanolic solution has been studied following the molar ratio method, also stability constant was studied and the complexes found to be stable in molar ratio1:1.an octahedral geometry was suggested for PdL1L2, PtL1and AuL1L2 complexes, square planar was suggested for AuL1 and PdL1complexes,while CuL1L2 complex has a square pyramidal geometry. Cytotoxic effect of theprepared complexes as well as ligands was evaluated against Hep-2 cell line using four different concentrations (625, 1250, 2500&5000 µg/ml) respectively in an exposure time 48 hrs comparing this effect with control positive Cis-Pt as reference drug. The obtained results refers to the higher inhibition rates of all complexes and their ligands and ligand (L1) and its complexes give more activity against tested cell than ligand (L2) and its complexes comparable with control positive .
This study was conducted during the spring season of 2023-2024 and the fall season of 2024-2025 at the fields of the College of Agricultural Engineering Sciences, University of Baghdad, to investigate effects of irrigation intervals I1 ,I2 (3 and 6 days) , soil amendment with zeolite at three concentrations Z0 ,Z1,Z2 (0, 4, and 8 g. kg soil⁻¹), and foliar spraying with kaolin for three concentrations C0,C1,C2 (0, 0.5, and 1 g .L⁻¹). The results revealed that the treatment I1Z2C2 significantly excelled in leaf area, chlorophyll concentrations, and yield for both seasons, achieving 31.0 dm², 21.5 mg per 100 g fresh weight, and 1984.7 g in the first season, and 34.08 dm², 23.6 mg per 100 g fresh weight, and 2526.3 g in the

The prepared AlO-AM and AlO-AP were characterized by Fourier-transform infrared, differential scanning calorimetry , thermogravemetric analyzer and particle size distribution. Adsorption equilibrium isotherms, adsorption kinetics and thermodynamic studies of the batch adsorption process were used to examine the fundamental adsorption properties of phenol (P) and p-chlorophenol (PCP). The experimental equilibrium adsorption data were analyzed by three widely used two-parameters Langmuir, Freundlich and DubininRadushkevich isotherms. The maximum P and PCP adsorption capacities based on t

The molding method is used to prepare sheets of UPE / sawdust composite and UPE / chopped reeds composite. The mechanical properties were studied including flexural strength and Young's modulus for the samples at normal conditions (N.C). The Commercial wood, UPE and its composite samples were immersed in water for about 30 days to find the weight gain (Mt%) of water for the samples, also to find the effect of water on their flexural strength and Young's modulus. The results showed that the samples of UPE / chopped reeds composite gained highest values of flexural strength (24.
