Pages 1-9 Ganesamoorthy Thirunarayanan Abstract A series containing sixteen titled pyrazoline derivatives have been synthesized by perchloric acid catalyzed cyclization cum acetylation of 3- hydroxyphenyl chalcones, hydrazine hydrate and acetic anhydride by refluxing condition. The yields of the synthesized 1 N-acetylpyrazolines were found to be more than 90%. These 1-acetylpyrazolines were characterized by their physical constants and spectral data. The antioxidant

Pages 11-19 Ali Abd Ali, Rana Hammza, Asim Balakit, Ahmed Al-Amiery and Emad Yousif Abstract The effect of 3-[(4- bromo-5- methylthiophen-2- yl) methylene amino]-2-isopropyl quinazolin-4(3- H) one (3-4- 5QZ) as a corrosion inhibitor was studied using weight loss measurement. The rate of corrosion was found to be decreased with increasing inhibitor concentration. The adsorption of (3-4-5QZ) on

Pages 21-31 Yousry Ghazaw, Tarek Elmitwalli and Abdul Razzaq Ghumman Abstract Water scarcity is one of the most sensitive issues of this century. Several countries are posed with the same problem of water scarcity in the Kingdom of Saudi Arabia (KSA). Thus, an optimal use of various water resources, including rainwater, is extremely crucial. However, the quality of

Pages 33-44 Tarneem O. Barayyan, Arshpreet Kaur and Shilpa Shilpa Abstract Rapid advancements in wireless sensor network have significantly supported the wireless body area networks (WBAN). In WBAN, especially in medical application, the energy efficiency of the sensor nodes is critical in the Intra-body communication level. In this case, the communication occurs between the sensor nodes (placed inside

Pages 45-54 Jibril Y., Salawudeen A. T., Salawu A. and Zainab M.  Abstract The aim of the present study is to build an intelligent Proportional-Integral- Derivative (PID) controller for deep space antenna position control using a modified artificial fish swarm optimization algorithm. The PID controller remains the most widely used controller in the engineering industries due to its ease

Pages 55-61 Mohammed N. Alghamdi Abstract This paper reports the preparation of mica-reinforced polypropylene composites by twin-screw extrusion and characterization of various properties. The composites were prepared by the varying weight percentages of the filler up to 40%. Structural identification was carried out by Fourier Transform Infra-red spectroscopy and shifting of few functional groups was noted. Mechanical properties such as
