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

The financial markets are one of the sectors whose data is characterized by continuous movement in most of the times and it is constantly changing, so it is difficult to predict its trends , and this leads to the need of methods , means and techniques for making decisions, and that pushes investors and analysts in the financial markets to use various and different methods in order to reach at predicting the movement of the direction of the financial markets. In order to reach the goal of making decisions in different investments, where the algorithm of the support vector machine and the CART regression tree algorithm are used to classify the stock data in order to determine

Show MoreThe study aimed to identify the awareness degree of teacher students in the department of Arabic language and their supervisors at Al-aqsa University for their future roles in the age of knowledge. To achieve this objective, descriptive- analytical approach was used. The instruments of this study were two questionnaires: first one consist of (20) item for teacher students, and the second consist of (27) item for educational supervisors which covered three roles: professional, technological, and humanitarian. The sample was (120) student selected randomly, and (39) supervisors of Arabic language. The result revealed that the mean of degree awareness of teacher students and their supervisors of future role are (3.857), (3.472) respectively

The grey system model GM(1,1) is the model of the prediction of the time series and the basis of the grey theory. This research presents the methods for estimating parameters of the grey model GM(1,1) is the accumulative method (ACC), the exponential method (EXP), modified exponential method (Mod EXP) and the Particle Swarm Optimization method (PSO). These methods were compared based on the Mean square error (MSE) and the Mean Absolute percentage error (MAPE) as a basis comparator and the simulation method was adopted for the best of the four methods, The best method was obtained and then applied to real data. This data represents the consumption rate of two types of oils a he
