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...
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 This project work present the alkylating reaction of [Pt2(μ-S)2(PPh3)4] with boronic acid alkylating agents.The reactivity of the metalloligand [Pt2(μ-S)2(PPh3)4] with the boron-functionalized alkylating agents BrCH2(C6H4)B(OR)2 (R = H or C(CH3)2) was investigated by electrospray ionization mass spectrometry (ESI-MS) in real time using the pressurized sample infusion (PSI). The macroscopic reaction of [Pt2(μ-S)2(PPh3)4] with one mole equivalent of alkylating agents BrCH2(C6H4)B{O...
ABSTRACT There are large areas of Nigeria and probably of West Africa that have never been visited or studied by a geologist or geophysicist. Not so in the region surrounding the Benue Trough. This area has repeatedly attracted a lot of attention in the past, and with the advent of plate tectonics the available geological and geophysical data from the region have been interpreted in various ways to suit different tectonic models. No attempt is made here to review the relevant published work o...
Abstract - Igneous intrusives of basic to intermediate (syenilic) compositions in the Lowcr Bcnue Trough had produced contact cffccts which ro.lge from the lowcr albite- cpidotc hornfels to the cordierite hornfels facies on the host sedimentary rocks which vary mainly from pelitic to calcareous pelitic types. Contact effects of low intensity and size were produced by three smaller igneous bodies of basic composition whose thicknesses range from 1 to 3 m. The mineral assemblages of the aureole...
ABSTRACT As a result of poor performance in statistics introductory course among the students in the universities; the study wanted to find out the factors that influence the performance of students. The purpose of the study was to conceptualize and empirically test ordinal logistic model on the factors affecting students’ statistics performance in public universities. Students’ performance was indicated by the grades they scored in the past statistical courses they undertook. The predict...
