ABSTRACT A study of the semiannual variation of the Monthly mean Dst-related disturbance in H and Z components of the geomagnetic field has been carried out. Magnetograms from fifteen (15) geomagnetic stations in the high- mid- and low latitudes, and which includes three of the stations used in computing the Dst index have been analyzed. Sixty-one years data (1950-2010) was utilized. The H-component (Hdiff) and Z-component (Zdiff) of the Dst-related disturbance were computed by removing the s...
A good understanding (If the structure and mode of evolution of the continental margin of Nigeria is crucial for many reasons. In terms of hydrocarbon accumulation, the area is of high economic importance as demonstrated by the high level of exploration activities that has been maintained in the area especially in the last three decades. The fishing industry would also benefit from a proper understanding of the bathymetry and morphology of the margin. Nigeria's scientific institutions have ye...

ABSTRACT Scale formation has become a big burden to sugar manufacturing industries, especially in evaporators, this is because of the characteristics of cane juice which is allowed in evaporators. Evaporators are used to evaporate as much water as possible from the juice using exhaust steam from the powerhouse as the heating medium so as to concentrate the juice which is called syrup (that is the juice leaving the evaporator) and the juice entering the evaporator is termed as clear juice. S...
ABSTACT Palmprint recognition has been investigated over ten year years. Palmprint is proven to be distinguishable from other features because of number of attributes. These attributes include color, clarity, position, continuity, length and variation in thickness. Lines are represented in a very efficient way and it needs low storage and consistency in detection and these are efficient for shape matching involving large database. But there will always be a problem of missing or broken lines ...
ABSTRACT Many calculations on atomic collisions and scattering processes have been performed on electron impact excitation of the lowest autoionizing state of rubidium, but not much attempt has been made with positron impact which is of equally fundamental importance and is receiving attention nowadays with the availability of improved positron beam experiments. So, in this study, total cross-sections, differential cross-sections, lambda parameter, R parameter and the alignment parameter...
ABSTRACT The rapid increase in traffic intensity, axle loading, rigorous climatic changes and commercial road transport continues to impose severe demands of load and environment on the highway system. Bitumen mostly used as a binder for road construction, waterproofing agent, coating, and insulation among others has poor mechanical and thermal properties. Different synthetic binder modifies that are being used to improved performance lead to environmental pollution during disposal. Therefore...
ABSTRACT Atomic collision cross sections are of interest because they can show the collision dynamics involved in the scattering process. There has been an upsurge in interest on positron collision processes due to recent advancement in positron beam experiments. In these studies, alkali metal atoms receive preference due to their simple electronic structure and spectra. We have calculated differential cross-sections, integral cross-sections, lambda (λ) parameter and the alignment parameter ...
ABSTRACT Iron industry in Kenya is dependent on imported raw materials. Local deposits of iron ore have been identified at various places in the country but not much has been done to determine whether the deposits are viable in quantity and quality for commercial exploitation. The location and delineation of the iron deposits and formation in the Mbeu area appraises the potential of such mineralization. Ground magnetic survey of Mbeu area was conducted to investigate subsurface geology on the...
Abstract This thesis consists of two parts. The first part deals with existerice and approximation techniques for finding solutions of operator equations or fixed points of operators belonging to certain classes of mappings. The classes of mappings studied include the K-posztz~~dee finzte operators, the suppressive mappings and accretive-type rntippings. In particular, it is proved that for a real Banach space X, the equation Au = f , f E X, where A is a Kpd operator with the same domain�...

Abstract We find two new classes of exact solutions to the Einstein-Maxwell system of equations. The matter distribution satisfies a linear equation of state consistent with quark matter. The field equations are integrated by specifying forms for the measure of anisotropy and a gravitational potential which are physically reasonable. The first class has a constant potential and is regular in the stellar interior. It contains the familiar Einstein model as a limiting case and we can generate ...
