The formation, structural characterization of mixed ligand complexes of Co II, Zn II, Cd II and Hg II metal ions with the Schiff base ligand (Z)-3,4,5-trihydroxy-N'-(4-hydroxybenzylidene) benzohydrazide and 8-hydroxyquinolineare reported. Ligand and complexes were characterized by analytical and spectroscopic analyses including; FTIR, electronic and 1H, 13C-NMR spectroscopy, microanalysis, chloride content, thermal analysis, magnetic susceptibility and conductance. Physico-chemical techniques indicated the formation of complexes with fourcoordinated arrangement in the solid and solution state. Biological activity of the prepared ligand and their mixed complexes were screened for their antimicrobial activity against four bacterial species (Staphylococcus aureus and Bacillus subtitles (G+)), Enterobacter and Escherichia coli (G-)). Biological data showed that complexes become potentially more active against these tested bacteria compared with the free ligands
Electronic spectra and kinetic studies of the hydrolysis of trans complexes where fernet acidic media,where carried out fairly
Image of landsate-7 taken by thematic mapper was used and classified using supervised method. Results of supervised classification indicated presence of nine land cover classes. Salt-soils class shows the highest reflectance value while water bodies' class shows the lowest values. Also the results indicated that soil properties show different effects on reflectance. There was a high significant positive relation of carbonate, gypsum, electric conductivity and silt content, while there was a week positive relation with sand and negative relation with organic matter, water content, bulk density and cataion exchange capacity.

The platelet activity and some immunological aspects of
coronary heart disease CIID were investigated by employing platelet count and serum levels of IgG,IgM and lgA,C3 and C4.Three groups of patients were investigated : patients with ischemic heart disease IHD, patients with lliD+hypcrtension and patients with IHD+unstable angina.The results revealed that the mean of platelets (mm') was significantly reduced in IHD+unstable angina group
2.72.L I.l2 compared with conrol b'TOUp 8.13±2.72.
With respect to the immunological study, the re;;ults revea
... Show MoreAn oxidative polymerization approach was used to create polyaniline (PANI) and Fe2O3 /PANI nanoparticle combination. Various characterization approaches were used to investigate the structural, morphological, and Fe2O3 /PANI nanoparticle structures. The findings support the synthesis of polycrystalline nanoparticle PANI and Fe2O3 /PANI spherical nanoparticle composites. Gram-positive bacteria are tested for antibacterial activity. Various quantities of Nanoparticles of PANI and Fe2O3 /PANI nanoparticle composites were used to test Staph-aureus and gram-negative bacteria, E-coli, and candida species. PANI has antibacterial properties against all microo

This research shows the problem of the economic development of underdeveloped countries in an unconventional way, as these papers explain the problems of the economic development. This research not only reviews the problems, but it illustrates them in a philosophical way, basis of the data of modernity, this mean it is a process of connecting between the absence of the modernity values and the failure of development in underdeveloped countries. The Search follows the descriptive approach to get to the goal of search by four main axes. The first axis includes clarifying modernity and its principles, the second axis includes clarifying the economic development , the third axis includes the features of the mod

Proverbs are considered as a major source of ancient events and happenings. Similar to other past events related to life, proverbs have many important and famous values in people's life. This study will shed lights on the use of proverbs as short sentences based on long experiences. The aim of the study is to explicate the roles, and the importance of proverbs in our life and how they are used to convey thoughts to people throughout simple words with denotation. Thus, proverbs explicate the truth and experience of our grandfathers when directed for criticism. Few proverbs were used by writers to criticize, mimic and reprint their personalities. Hence, proverbs will achieve portions of the unique roles of understanding. The model to
