NUMERICAL INVESTIGATION OF GROUNDWATER REMEDIATION USING STEAM INJECTION
A.A. Dare, A.A. Adegbola
Abstract:
Groundwater is of major importance to civilization, because it is the largest reserve of drinkable water in regions where humans can live. The pollution of groundwater by Non Aqueous Phase Liquid (NAPL) has become an increasing concern with industrialization. The effects of these pollutants may remain in the aquifers for many years because the residence time of groundwater is very slow. This work is thus aimed at investigating the remediation of polluted groundwater using steam injection.

NEEM OIL AS A SOURCE OF FUEL ENERGY
K. Hamza, E.O Ajala
Abstract:
As we all know that the petroleum resources are limited and are non-renewable in nature, we must start to think about the alternatives as we are likely to run out of the petroleum resources in few decades, Bio-fuel is renewable energy fuel that can be used directly in any existing, the research emphasis the feasibility of using Neem oil as a substitute of Diesel and Kerosene, Physical properties like kinematic viscosity, carbon residue, flash point, fire point and Absorption has been determined.

Analysis of the transposition of frequency and itsfidelisation: application to aFrequency Modulation radio channelin Lubumbashi, DRC
MbanguTshingej Néné, Kasama Mumba Egide, Cike Nkumwimba1, Banza Wa Banza Bonaventure
Abstract:
The study aimed to study the selectivity of the frequency of a signal emitted by a broadcasting station in frequency modulation (FM). The measurements and analyzes were made using Persian and Spectrum Analyzer in the laboratory of the Regulatory Authority of Posts and Telecommunication of Congo (ARPTC). This study synthesized measurements and spectral analyzes made on the various FM radio channels of the city of Lubumbashi. The observation made reveals that some local channels do not respect the frequency excursions and the bandwidths allocated to the frequency modulation; this is particularly the case of Tam-Tam radio station in Africa. Thus, in this work, we proceeded by measuring the transmission frequency of the aforementioned radio station, and its spectrum delimited by the bandwidth. The analysis of the bandwidth of Tam-Tam radio in Africa shows an expansion of its spectrum, whose bandwidth is 500 kilohertz, instead of 300 kilohetz, as recommended in FM, with the consequence of jamming stations located immediately to the left and to the right.
