Sokoto Basin is one of the major sub-basins of the Illummedan basin of West Africa. The Basin lies in the sub-Saharan Sudan belt of West Africa in zone of Savanna-type vegetation generally classified as semi-arid. It lies in northwestern Nigeria between latitudes 8°301 and 14°001 N and longitudes 3°301and 7°001 E occupying a total of […]

The study investigates the rate of corrosion and its impact on mild steel. The test was carried out in different selected environments, to understand their environmental influence and the rate of corrosion in that environment namely: 0.1M of Hydrochloric acid, Underground (soil), Atmosphere, Salt water and Fresh water. A mild steel of diameter 1.2cm and […]

The effect of pulsed Nd-YAG laser welding of AISI 304 to AISI 430 stainless steel was investigated. Laser parameters such as (peak power, pulse duration and welding speed) were changed and the change in properties was measured. Optical microscope was used to examine cracks, pores and weld geometry of welded samples. The results of tensile […]

The formation of rainfall has been studied empirically and theoretically within the compass of physics accompanied by a meteorological background. The study shows the energy transformations from molecular potential energy at ground level after the possession of heat from the sun to kinetic energy at the atmosphere after evaporation and the retransformation from kinetic in […]

This paper describes a gully erosion study undertaken at Umuagwo – Urualla in the Ideato North Local Government Area of Imo State, Nigeria. The study involved the morphometric measurement of the gully, collection of soil samples for geotechnical analysis, geophysical investigation (using Vertical Electric Sounding) to determine the subsurface complexities of the gully area, peizometric […]

Electroless nickel-phosphorus (EN) coating is a chemical reaction process results in a reduction of the metallic ion. It depends on catalytic action. In thiswork, several samples of base metal were coated with (Ni-P) deposit. Then nano-sized (40nm SiC) and micro-sized (11.22µm SiC) particles were added separately to the bath to be incorporated into the coating […]

Studies on extreme temperature are beneficial to human understanding of extreme events. Decision-makers and researchers in climatology will benefit from knowledge about the behaviour of extreme temperature, as appropriate policies and plans can be drawn to prepare the general public for changes due to extreme temperature. This can be achieved through Extreme Value of Analysis […]

For keeping the integrity of a message data we can commonly use a Checksum or a CRC (Cyclic Redundancy Code). It is well-known that there is very little information available about their relative performance and effectiveness. Despite that fact we would agree that the choice of the CRC-computing method should be a successful task. For […]

In India, of late much emphasis is being given for bivoltine silkworm rearing to boost up the quality silk production matching international standards. Indian sericulture is dominated by the usage of only one or two bivoltine hybrids, either double/single, that are developed for usage under optimal conditions particular for favourable seasons only. There is a […]

The aims of this study were to determine energy (input-output) and energy cost analysis and prediction of output energy for maize production in Shooshtar County of Iran, Data were collected from 40 maize farms by using a face to face questionnaire method in 2015. The results revealed that in maize production, total energy input was […]
