Osman, E. O., A. M. Mahmoud, S. S. El-Mosallamy, and H. B. El-Nassan, "Electrochemical synthesis of tetrahydrobenzo[b]pyran derivatives in deep eutectic solvents", Journal of Electroanalytical Chemistry, vol. 920, pp. 116629, 2022. AbstractWebsite

The current work reported the first synthesis of 4H-pyran derivatives via one pot reaction of dimedone, malononitrile and aromatic aldehydes under electrochemical (EC) synthesis conditions in deep eutectic solvents (DES). The effects of different experimental factors like; solvent, electrodes, supporting electrolytes, temperature and reaction time were studied to optimize the reaction conditions in order to maximize the products yield. The reaction proceeded completely using different substituted aldehydes except for hydroxybenzaldehydes where oxidation seems to hinder the formation of the target reaction product. Combining EC and DES afforded the pyran derivatives in high yields within short reaction times and in highly pure forms. Moreover, the use of DES eliminated the need for supporting electrolyte. The DES have been recycled two times without a significant loss in the catalytic activity. The procedure was highly efficient, catalyst-free and eco-friendly as evident from the calculations of the green chemistry metrics.

Osman, E. E. A., "Analytical investigation of different mathematical approaches utilizing manipulation of ratio spectra.", Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, vol. 188, pp. 469-477, 2018 Jan 05. Abstract

This work represents a comparative study of different approaches of manipulating ratio spectra, applied on a binary mixture of ciprofloxacin HCl and dexamethasone sodium phosphate co-formulated as ear drops. The proposed new spectrophotometric methods are: ratio difference spectrophotometric method (RDSM), amplitude center method (ACM), first derivative of the ratio spectra (1DD) and mean centering of ratio spectra (MCR). The proposed methods were checked using laboratory-prepared mixtures and were successfully applied for the analysis of pharmaceutical formulation containing the cited drugs. The proposed methods were validated according to the ICH guidelines. A comparative study was conducted between those methods regarding simplicity, limitations and sensitivity. The obtained results were statistically compared with those obtained from the reported HPLC method, showing no significant difference with respect to accuracy and precision.

Although it is well documented that moderate exercise enhances cell-mediated
immunity, effect of moderate exercise on breast milk leukocytes has not been studied yet. So,
the aim of this study was to investigate the effect of moderate exercise on breast milk
leukocytes in exclusively breast-feeding mothers. Forty-seven exclusively breast-feeding
mothers at 1st to 5th month postpartum were randomized into two groups. Group A received
breast-feeding and nutritional counseling and engaged in moderate aerobic exercise for 4
weeks with a total of 12 sessions. Group B received only the same breast-feeding and
nutritional counseling for 4 weeks. Both groups were evaluated pre and post-intervention.
The outcome measures were maternal anthropometric parameters and breast milk total and
differential leukocytes counts. Post-intervention, there was a non-significant difference in the
maternal anthropometric parameters (P > 0.05) while there was a highly significant increase
in breast milk total and differential leukocytes counts (P = 0.001) in favor of group A. There
was a significant inverse relationship between maternal anthropometric parameters and
lymphocytes count in group A. This study explored that moderate aerobic exercise during
exclusive breast-feeding was associated with increased breast milk total and differential
leukocytes counts.

Osman, T. A., Misalignment Effect on the Static Characteristics of Magnetized Journal Bearing Lubricated with Ferrofluid, , vol. 11, issue 3, pp. 195 - 203, 2001. AbstractWebsite

In this paper a generalized Reynolds equation suitable for misaligned hydrodynamic journal bearings lubricated by either Newtonian or non-Newtonian ferrofluid is developed. The equation has been solved numerically by the finite difference technique with an appropriate iterative method and the pressure distributions have been obtained. Design charts for all static characteristics (including load capacity, attitude angle, side flow, friction force and misaligned moments) under different misalignment conditions are presented. The effects of misalignment conditions on all these bearing-performance characteristics are analyzed. The results conclude that magnetic lubrication improves, in general, the bearing performance under misalignment.
