Early detection enhancement of the kick and near-balance drilling using mud logging warning sign
Publication date: Available online 2 October 2015 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Mohammed A. Ahmed, Omar A. Hegab, Ahmed Sabry Early kick detection is of great concern while drilling wells. The late kick detection can lead to uncontrolled blowout which increases the possibility of injury and potential lose of life and equipment. Causes of kick and the importance of early kick detection are introduced. Kick detection from mud logging real time data and kick detection in the offshore Nile Delta are discussed. Limitation of the conventional well control procedure in low permeable fo...

Time-fractional effect on pressure waves propagating through a fluid filled circular long elastic tube
Publication date: Available online 9 September 2015 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Essam M. Abulwafa, E.K. El-Shewy, Abeer A. Mahmoud The pressure waves propagating through an incompressible inviscid fluid that moves in a circular cylindrical long elastic tube are considered. The reductive perturbation method is used to derive the KdV equation from the hydrodynamic equations of the system. The Euler–Lagrange variational technique described by Agrawal has been applied to formulate the time-fractional KdV equation. The derived time-fractional KdV equation is solved by employing t...

Antimicrobial, analgesic, antioxidant and in silico study of synthesized salicylic acid congeners and their structural interpretation
Publication date: Available online 31 August 2015 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Jyotirmaya Sahoo, Sudhir Kumar Paidesetty A series of azosalicylic acid analogs were newly synthesized by coupling various aryl and heteroarylamine functionalities with salicylic acid nucleus. All the synthesized compounds were structurally confirmed by various modern analytical methods. The said synthesized compounds were screened to investigate their antimicrobial, analgesic and antioxidant activities. The compounds 4e and 4h showed excellent significant antibacterial activity against most of the bac...

Black berry juice attenuates neurological disorders and oxidative stress associated with concurrent exposure of aluminum and fluoride in male rats
The objective of this study was to assess the protective effect of black berry juice (BBJ) on the neurological disorders and oxidative stress induced by co-exposure to ALCL3 and NaF in male albino rats. Administration of either AlCl3 (200 mg/kg bw) or NaF (10 mg/kg bw) or both of them caused a significant increase in serum and brain TL, TC, TG as well as serum LDLC and VLDLC levels while serum HDLC level was decreased significantly. Additionally, brain neurotransmitter (DA and 5-HT) levels, AChE, Na-K ATPase activity and ATP values were decreased significantly but NE level was increased in rats administered Al or F alo...

Fungal keratitis: Rapid diagnosis using methylene blue stain
Publication date: Available online 19 August 2015 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Dalia Moemen, Tamer Bedir, Eman A. Awad, Adel Ellayeh Earlier and accurate diagnosis of the fungal infection in the cornea is necessary for effective treatment. In developing countries, microscopical evaluation is the most valuable and rapid diagnostic tool. Therefore we aimed to investigate the efficacy of methylene blue (MB) staining in comparison with potassium hydroxide (KOH) and calcofluor white (CW) stain. Corneal scraping from 48 cases with suspected fungal keratitis were included in the stu...

Some applications of Dα-closed sets in topological spaces
Publication date: Available online 18 August 2015 Source:Egyptian Journal of Basic and Applied Sciences Author(s): Osama Rashed Sayed, Ahmed Mostafa Khalil In this paper, a new kind of sets called Dα-open sets are introduced and studied in a topological spaces. The class of all Dα-open sets is strictly between the class of all α-open sets and g-open sets. Also, as applications we introduce and study Dα-continuous, Dα-open, and Dα-closed functions between topological spaces. Finally, some properties of Dα-closed and strongly Dα-closed graphs are investigated. (Source: Egyptian Journal of Basic and Applied Sciences)
