Abstract: In this study, a model of MHD convective tin-oxide(TiO₂) nanofluid flow over a cylindrical porous plate was examined. The governing equations of continuity, momentum, energy, and concentration modelled in terms of partial differential equations with boundary conditions were non-dimensionalised using the Buckingham’s π-theorem and then were transformed into ordinary differential equations using the regular perturbation technique, each of these equations was solved in isolation using Frobenius Method which gave the analytic solutions. The solutions obtained for the momentum, energy, and concentration were subjected to analysis which gave the results for the temperature profile, concentration profile, and velocity profile graphically. It was observed that, when the radiation parameter was increased, the temperature profile dropped; as the chemical reaction was increased, the concentration profile and the velocity profile were reduced; again as the magnetic field number was increased, it lowered the profile of the velocity. The velocity profile was enhanced with an increase in the porosity parameter, and this, as a result, tended to increase in the size of the pore spaces of the porous medium; the concentration profile, temperature profile, and velocity profile all improved as the nanofluid volume fraction increased.

Keywords: Nanofluid, MHD flow, Convection, Cylindrical Porous Plate, Analytical Solutions.

Abstract: Schiff base was synthesized by the condensation of o-phenylenediamine and 2-hydroxy-1-napthaldehyde. Its metal complexes were also prepared by reacting the Schiff with metal chlorides in ethanol.. The Schiff base and its metal (II) complexes were characterized by solubility test, melting and decomposition determination, FTIR, magnetic susceptibility, molar conductance analysis. Solubility test was carried on the Schiff base and the complexes which showed that they are all soluble in ethanol DMSO and DMF, but insoluble in water. From the FTIR result, Azomethine v(C=N) stretching vibration was observed at 1608 cm^-1 which shifted to 1707cm^-1 in manganese (II) complex, 1707cm^-1 in cobalt (II) complex, and 1707cm^-1 in zinc (II) complexes respectively. Also a broad band was observed in the Schiff base and the complexes at 3108cm^-1 which indicate presence of water of crystalliation to the complex structure. The complexes are paramagnetic except for zinc which is diamagnetic, non electrolytic in nature and have high thermal stability. Job’s method of continuous variation suggests 1:2 metal to ligand ratio. The antimicrobial studies of the Schiff base and its metal(II) complexes reveals that the metal(II) complexes show better activity when compared to that of the ligand.

Abstract: Lead is naturally occurring toxic metal found in the Earth’s crust. Its widespread use has resulted in extensive environmental contamination, human exposure and significant public health problems. In this research, adsorption studies were carried out for the removal of Pb2+ from aqueous solution. The carbons were activated using 40% Phosphoric acid. It was characterized using BET, SEM and FTIR methods of characterization. The BET analysis was used to determine the surface area which was gotten to be 1383 m2/g. The surface area of the chemically activated carbon from the SEM image is found to consist of highly packed bundles of deep long cylindrical pores and some pits indicating the good adsorptive capacity. The peaks obtained from the FT-IR analysis are O-H band, C-H stretch and nitrile triple (HC≡N) bond. Equilibrium adsorption data were modeled using Langmuir, Freundlich, Redlich-Peterson and Elovich models, Langmuir model fitted more compared to other models. Adsorption kinetic data were tested using pseudo-first order and pseudo-second order, the adsorption followed the pseudo-second order mechanism with a correlation coefficient (R2) of 0.9999.

Abstract: We have applied the principles of Lyra’s geometry in modifying the Reissner Nordström metric to develop the metric for charged black holes and derived the first two components of the metric from the modified Einstein’s field equation. In this paper we analysed the complex dynamical system for the trajectories of the charged particles in the context of lyra’s geometry based on Sen and Dunn’s modification of the coupled Einstein-maxwell equation. The analysis begins by formulating the modified geodesic equations of motion for the RN metric in Lyra's geometry. As a result some interesting properties of the interaction of charged particles with the Reissner blackhole are studied.

Abstract: Integrated geophysical and geochemical investigation was helpful in mapping areas of contamination in subsurface formation. Electrical resistivity surveys were carried out at a site of shallow hydrocarbon contamination and were correlated with geochemical analysis in Ikarama, aimed at investigation contamination plume of the subsoil. Thus, three (3) Electrical profiling were carried out using ABEM SAS 1000 terrameter, and six (6) subsoil samples were collected from the study area; which was analyzed using the Atomic Absorption Spectroscope (AAS) and UV Spectrophotometer and the analyzed result was compared with the World Health Organization Standard.  The result revealed high contamination content of lead (Pb) at profile 1, 18 mg/l and profile 2, 8.1302 mg/l, while Mn was 6.6611mg/l and 7.7778mg/l at profile 1 and profile 2 respectively. While for the TPH, we have high (404 mg/l) and (124 mg/l) contamination concentration at profile 1 and profile 2 respectively; both at the unsafe zone and low (25.8mg/l) at profile 3, known as the control zone. The very high contamination concentration values for all subsoil samples which exceeded the WHO permissible standard indicates that aquifer may likely be polluted by intrusion. It is advisable to carry out proper water treatment from source and soil degradation, for potable drinking water and cultivation of agricultural product respectively for social economic development.

The polymerization process involves the breaking of the double bond and the formation of a single bond between the monomers, resulting in a long-chain polymer. Addition polymers are characterized by their high molecular weight, high melting point, and high tensile strength. They are also resistant to chemical and biological degradation, making them useful in a wide range of applications.

Addition polymers have a wide range of applications in various fields due to their unique properties. For instance, they are used in the production of medical devices, such as catheters and implants, due to their biocompatibility and resistance to degradation. Due to their high electrical insulation properties, they are also used in producing electronic devices, such as circuit boards and displays. Addition polymers are also used to make adhesives, coatings, and paints due to their high adhesive properties and resistance to wear and tear.

The use of addition polymers in various applications brings about challenges and considerations that necessitate attention to their sustainable and effective utilization.

Abstract: Over time, the Differential Transform Method (DTM) has emerged as a powerful mathematical technique that can be deployed in solving differential equations like ODEs and PDEs. DTM was first presented by Anastassiou in the late 1980s and has since been widely used in various fields of mathematics, engineering, and physics (Chen, 2004). The DTM works by transforming the PDE into an algebraic equation, which can then be solved using standard algebraic techniques.

Abstract: We found the centripetal force to apply to atomic physics, which is very different from the accepted physics. We found the speeds and accelerations hidden in a circular smooth motion. We formulated some of why atomic physics was misformulated, and we proved the area and volume of spheres, different from the existing ones.

We set principles, like the ancient Greek philosophers, to formulate the theory.

We formulated the two different magnetic fields, producing a circularly rotating charge.

We found a consistent system of units required by atomic theory and showed that System International is inconsistent.

We have formulated the existence of the ether. An ether with low viscosity does not contradict the Mickelson-Morley experiment and much more, it does not contradict the geocentric system of the universe, where the earth is almost stationary.
