    Fully developed flow of non-Newtonian fluids in a straight uniform square duct through porous medium
    (University of Bahrain, 2017-06) Devakar, M.; Ramesh, K.; Chouhan, Sagar; Raje, Ankush
    In this paper, we have studied the flow of incompressible fluids in a straight square duct through the porous medium. The couple stress fluid model and Jeffrey fluid model are considered separately to study the flow properties. The governing partial differential equations have been solved numerically using finite difference method in each case. In both the cases, the variation of different flow parameters on the fluid velocity is illustrated graphically and the numerical results for the volume flow rate have been presented through tables. It is observed that, the velocity and volume flow rate decrease with an increase in couple stress parameter and porosity parameter, while the velocity and volume flow rate increase with an increase in Jeffrey parameter and pressure gradient.

    Quintic spline collocation method for fractional boundary value problems
    (University of Bahrain, 2017-06) Akram, Ghazala; Tariq, Hira
    The spline collocation method is a competent and highly effective mathematical tool for constructing the approximate solutions of boundary value problems arising in science, engineering and mathematical physics. In this paper, a quintic polynomial spline collocation method is employed for a class of fractional boundary value problems (FBVPs). The FBVPs are expressed in terms of Caputo’s fractional derivative in this approach. The consistency relations are derived in order to compute the approximate solutions of FBVPs. Finally, numerical results are given, which demonstrate the effectiveness of the numerical scheme.

    Solution of mixed integral equation in position and time using spectral relationships
    (University of Bahrain, 2017-06) Abdou, M.A.; Basseem M.,
    n this article, the existence of a unique solution of Fredholm–Volterra integral equation of the second kind is guaranteed. The Fredholm integral term is assumed in position with bad kernel, while the Volterra integral term is considered in time with continuous kernel. Under certain conditions and new discussions, the bad kernel will tend to a logarithmic kernel. Then, using Chebyshev polynomial, a main theorem of spectral relationships of Fredholm integral equation of the first kind with logarithmic kernel multiplying by a smooth kernel is stated and used to obtain numerically the Fredholm–Volterra integral equation of the second kind. Finally, numerical results are obtained and the error, in each case, is computed.

    2-Amino-4-(2,4-dihydroxyphenyl) quinoline-3-carbonitrile as sustainable corrosion inhibitor for SAE 1006 steel in 1 M HCl: Electrochemical and surface investigation
    (University of Bahrain, 2017-06) Verma, Chandrabhan; Quraishi, M.A.
    The corrosion inhibition efficiency of 2-amino-4-(2,4-dihydroxyphenyl) quinoline-3-carbonitrile (ADQC) on SAE 1006 steel has been investigated using electrochemical (EIS and Polarization), surface (SEM, EDX and AFM) and quantum chemical calculation methods. Results showed that inhibition efficiency increases with increasing ADQC concentration and maximum value of 96.12% was obtained at 25 mg/L concentration. EIS results showed the ADQC inhibits SAE 1006 steel corrosion becoming the adsorbate at metal/electrolyte interfaces. Polarization study showed that ADQC acts as cathodic type inhibitor. SEM, EDX and AFM finding supported the adsorption of ADQC on the mild steel surface. The quantum chemical calculations provide good insight about the adsorption and inhibition mechanism of ADQC. The experimental and quantum chemical calculation results were in good agreement.

    Determination of iron, cobalt and nickel ions from aqueous media using the alkali modified miswak
    (University of Bahrain, 2017-06) Moawed, E.A.; El-ghamry, M.A.; El-Hagrasy, M.A.; El-Shahat, M.F.
    This paper describes a simple, rapid, inexpensive method for the preparation of a new biosorbent based on the modification of miswak fibers by NaOH (AT-Miswak-F). The synthesized AT-Miswak-F sorbent was utilized as an efficient sorbent for the extraction and preconcentration of iron group metal ions from various water samples. In this study, it was found that Fe(III), Co(II) and Ni(II) ions were completely extracted (100%) at pH range of 3–7 and flow rate of 0.3–2.0 mL min _1. Also, the sorption capacity of AT-Miswak-F for Fe(III), Co(II) and Ni(II) are 0.54, 0.24 and 0.15 mmol g _1, respectively. Equilibrium was best described by Freundlich isotherm model (R2 =0.793) and the initial rate constants were 0.077, 0.054 and 0.035 mmol g_1 min _1, respectively. Under the optimized conditions, the method exhibited a detection limit of 1.4, 2.8 and 2.1 ng mL _1 for Fe(III), Co(II) and Ni(II) ions in water samples with relative standard deviations of 2.6% (n= 4). The method was successfully applied for the determination of Fe(III), Co(II) and Ni(II) ions in sea, ground and contaminated water samples.

    Shortening full-length aptamer by crawling base deletion – Assisted by Mfold web server application
    (University of Bahrain, 2017-06) Gopinath, Subash C.B.; Lakshmipriya, Thangavel; Arshad, M.K. Md; Voon, C.H.; Adam, Tijjani; Hashim, Uda; Singh, Harbant; Chinni, Suresh V.
    Systematic Evolution of Ligands by EXponential enrichment (SELEX) is the method to select the specific aptamer against a wide range of targets. For this process, the initial library usually has a length of random sequences from _25 and it reaches over 100 bases. The lengthy sequences have disadvantages such as difficult to prepare, less stable and expensive. It is wise to prefer shorter version of aptamer for a wide range of applications including drug delivery process. It is a common practice to shorten the full-length aptamer by mapping analyses and it is tedious. Here, we used a crawling method to shorten the aptamer by different sequential deletion of bases from both 50 and 30 ends, assisted by Mfold web server application. Two different kinds of aptamer with varied lengths (randomized region of 30 and 74 bases) were desired for this study, generated against Influenza A/Panama/2007/1999 (H3N2) and gD protein of Herpes Simplex Virus-1. It was found that shortening the aptamer length by crawling pattern is possible with the assistance of Mfold web server application. The obtained results resemble the shortened aptamer derived by mapping analyses. The proposed strategy is recommended to predict the shorter aptamer without involving any wet experimental section.

    Assessment of adsorption kinetics for removal potential of Crystal Violet dye from aqueous solutions using Moroccan pyrophyllite
    (University of Bahrain, 2017-06) Miyah, Youssef; Lahrichi, Anissa; Idrissi, Meryem; Boujraf, Sa?d; Taouda, Hasnae; Zerrouq, Farid
    This study involves the adsorption of Crystal Violet (CV) dye adsorbed from solution on the pyrophyllite’s surface. The batch technique was used under a variety of conditions to produce quantitative adsorption, namely amount of adsorbent, dye concentration, contact time, pH solution and temperature. The maximum adsorption capacity of Crystal Violet on pyrophyllite was 9.58 mg/g for 10 mg/L of CV concentration, pH =6.8 at a temperature 20 _C and 1 g/L of adsorbent. This study of adsorption kinetics was carried out within framework of three models: intraparticle diffusion, pseudo-first order and pseudo-second order. The experimental isotherm data were analyzed using Langmuir and Freundlich models. Different thermodynamic parameters have shown spontaneous reaction with endothermic nature (The estimated value for DG was_7.64 kJ/mol at 293 K). Various techniques for characterizing the adsorbent were applied including X-ray diffraction (XRD), X-ray fluorescence spectroscopy (XRF), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) coupled by energy dispersive X-ray spectroscopy (EDX). In addition, the regenerated adsorbents technique was reused several times; this demonstrated an economical aspect of using pyrophyllite which underlines the re-use importance considering the material capacity to regenerate.

    Money laundering regulatory risk evaluation using Bitmap Index-based Decision Tree
    (University of Bahrain, 2017-06) Jayasree, Vikas; Balan, R.V. Siva
    This paper proposes to evaluate the adaptability risk in money laundering using Bitmap Index-based Decision Tree (BIDT) technique. Initially, the Bitmap Index-based Decision Tree learning is used to induce the knowledge tree which helps to determine a company’s money laundering risk and improve scalability. A bitmap index in BIDT is used to effectively access large banking databases. In a BIDT bitmap index, account in a table is numbered in sequence with each key value, account number and a bitmap (array of bytes) used instead of a list of row ids. Subsequently, BIDT algorithm uses the ‘‘select” query performance to apply count and bit-wise logical operations on AND. Query result coincides exactly to build a decision tree and more precisely to evaluate the adaptability risk in the money laundering operation. For the root node, the main account of the decision tree, the population frequencies are obtained by simply counting the total number of ‘‘1” in the bitmaps constructed on the attribute to predict money laundering and evaluate the risk factor rate. The experiment is conducted on factors such as regulatory risk rate, false positive rate, and risk identification time.

    (University of Bahrain, 2017-06) Vekariya, Rajesh H.; Patel, Kinjal D.; Rajani, Dhanji P.; Rajani, Smita D.; Patel, Hitesh D.
    A convenient, one-pot, multi-component protocol for the preparation of 2-(1-(2-oxo-2Hchromen-3-yl)ethylidene)hydrazinecarbothioamide derivatives has been achieved. Here, firstly we have reported the synthesis of 3-acetyl-2H-chromen-2-one using starch sulfuric acid and cellulose sulfuric acid as biodegradable catalysts. Subsequently, we also carried out the reaction of isothiocynates, hydrazine hydrate and 3-acetyl-2H-chromen-2-one in the presence of catalytic amount of glacial acetic acid in refluxing ethanol to afford corresponding 2-(1-(2-oxo-2H-chromen-3-yl)ethyli dene)hydrazinecarbothioamide derivatives in high to excellent yields. All synthesized compounds were screened for antimicrobial activity. All compounds were found to show good to excellent activity against Escherichia coli MTCC 443.
