Mathematical Modelling of insitu-Bioremediation of Crude Oil Polluted Soil

A bioremediation model was developed for the bioremediation of a crude oil polluted soil. The developed mathematical model considers a batch process. The model was designed to predict the quantity of crude oil remaining per time in crude oil contaminated areas during in-situ bioremediation. The model can be used to monitor the progress of soil bioremediation by monitoring crude oil residual concentration per time. Comparing the results of the simulations of the derived model to the results of an existing model, shows that the new model is valid and reliable for monitoring the progress of any batch bioremediation process of crude oil polluted soils

A Review On The Comparative Roles Of Mathematical Softwares In Fostering Scientific And Mathematical Research

Mathematical software tools used in science, research and engineering have a developmental trend. Various subdivisions for mathematical software applications are available in the aforementioned areas but the research intent or problem under study, determines the choice of software required for mathematical analyses. Since these software applications have their limitations, the features present in one type are often augmented or complemented by revised versions of the original versions in order to increase their abilities to multi-task. For example, the dynamic mathematics software was designed with integrated advantages of different types of existing mathematics software as an improved version for understanding numerical related problems for advanced mathematical content (advanced simulation). In recent times, science institutions have adopted the use of computer codes in solving mathematics related problems. The treatment of complex numerical analysis with the aid of mathematical software is currently used in all branches of physical, biological and social sciences. However, the programming language for mathematics related software varies with their functionalities. Many invaluable researches have been compromised within the confines of unacceptable but expedient standards because of insufficient understanding of the valuable services the available variety of mathematical software could offer. In the developing countries, some mathematical software like Matlab and MathCAD are very common. A comparative review for some mathematical software was embarked upon in order to understand the advantages and limitations of some of the available mathematical software

Theoretical Design of Lightning Panel

The light trapping device (LTD) was theoretically designed to suggests the best way of harvesting the energy derived from natural lightning. The Maxwell's equation was expanded using a virtual experimentation via a MATLAB environment. Several parameters like lightning flash and temperature distribution were consider to investigate the ability of the theoretical lightning panel to convert electricity efficiently. The results of the lighting strike angle on the surface of the LTD shows the maximum power expected per time. The results of the microscopic thermal distribution shows that if the LTD casing controls the transmission of the heat energy, then the thermal energy storage (TES) can be introduced to the lightning far

Verification of Aerosols Loading Over Kano: A Theoretical Estimation via Mathematical Rudiments

The danger of aerosols loading is dangerous to human as well as the atmosphere. The estimation of the aerosol loading can be very difficult in any location in West Africa because of its proximity to the influence of the north-east winds from the Sahara desert. An established analytical and statistical approach was used to estimate the aerosol loading over Kano. The maximum aerosol retention over Kano is 31.28%. The atmospheric constant which also describes the aerosols loading over Kano was found to be 0.708 and 0.8984. This means that Kano may be facing high thermal discomfort as well as spread of disease if not checked

Optimizing the Efficiency of Measuring Instruments in Ouagadougou- Burkina Faso

At the moment, AERONET or AMMA database shows a large volume of data loss. With only about 47% data set available to the scientist, it is evident that accurate nowcast or forecast cannot be guaranteed. The calibration constants of most radiosonde or weather stations are not compatible with the atmospheric conditions of the West African climate. A dispersion model was developed to incorporate salient mathematical representations like a Unified number. The Unified number was derived to describe the turbulence of the aerosols transport in the frictional layer of the lower atmosphere. Fourteen years data set from Multi-angle Imaging SpectroRadiometer (MISR) was tested using the dispersion model. A yearly estimation of the atmospheric constants over Ouagadougou using the model was obtained with about 87.5% accuracy. It further revealed that the average atmospheric constant for Ouagadougou-Niger is a_1 = 0.626, a_2 = 0.7999 and the tuning constants is n_1 = 0.09835 and n_2 = 0.266. Also, the yearly atmospheric constants affirmed the lower atmosphere of Ouagadougou is very dynamic. Hence, it is recommended that radiosonde and weather station manufacturers should constantly review the atmospheric constant over a geographical location to enable about eighty percent data retrieva

Virtual Observation of Femtosecond Spin Dynamics Mechanism in Graphene

Abstract—The mechanism of the femtosecond spin dynamics is still not properly understood. The remodeled Bloch – Schrödinger equation was incorporated into the Hamiltonian. The mechanism of the femtosecond dynamics was investigated under three quantum states. The spin relaxation mechanism operated in a single continuous time scale (>70ps) which was in variance with knownpostulate. The transient reflectivity was measured to be within an angular range of 18.6o to 90.0o at a pulse range of 1MHz to 6.5 MHz. Beyond the pulse intensity of -2.5, the system elapsed into a quasi-equilibrium state which explains the independence of the magnetic moment on the pulse intensity. Different possibilities of the femtosecond spin dynamics were worked out for future study

A Project Design for Air Pollution Studies Over Bobodioulasso-Burkina Faso

This paper introduces a project design on estimating air pollution over geographical regions that have a mono-source of data acquisition. Fifteen years (2000-2013) aerosol optical depth dataset was obtained from the Multi-angle Imaging Spectro-Radiometer (MISR). The peculiar design that has been discussed in this paper focusses on human health and environmental disturbances. The secondary datasets that were generated from the primary data were aerosol loading, particles sizes, Angstrom parameter, and the statistics of the primary dataset. A computational data treatment was introduced for the determination of data reliability of the dataset. The techniques highlighted in this study are germaine to be reproduced in several geographical locations
