ELECTRONIC AND VIBRATIONAL ABSORPTION SPECTRAL STUDY OF SOME N - SUBSTITUTED ANILIDES AND SULPHONANLIDES

ABSTRACT  The electronic and vibrational absorption spectra of some N - substituted anilides and sulphonanilides have been studied. The different bands observed have been assigned to the proper electronic and vibrational transitions respectively. The solvent dependence of n - n* and n- n* transitions in these compounds was investigated by studying their UV spectra in pure organic solvents of different polarities. The longest wavelength band displayed by the anilides and the sulphonanilide i...

Antidiabetic Properties of Total Phenol Content of Zanthoxylum zanthoxyloides Leaves on Albino Rats

ABSTRACT    In this study, we evaluated the effect of the total phenol extract of Zanthoxylum zanthoxyloides leaves on oral glucose tolerance, lipid profile, liver function, oxidative stress parameters, and pancreas histopathology in diabetic rats. Diabetes was induced in rats by administration of alloxan monohydrate in a dose of 130 mg/kg b/w. Total phenol content of Z. zanthoxyloides leaves was administered to rats at 100, 200 and 400 mg/kg b/w daily for 15 days. Blood glucose was measur...

Numerical Solution Of Special Second Order Initial Value Problems By Hybrid Type Method

INTRODUCTION The foreign policy of a nation is a reflection of its national demands, needs and aspirations. Much as there is a relationship between a state national interest and those foreign to it. The study is aimed at examining the foreign policy of Nigeria and its national interest under President Goodluck Ebele Jonathan. Foreign and national policy issues are related products of the same political system and are designed to define and implement overall national purposes. Foreign and nati...

Karyotypes of some Ghanaian Shield-Bugs and the Higher Systematics of Pentatomidae(Hemiptera : Heteroptera)

ABSTRACT Data on 2n-numbers of some fifty-five (55) species , belonging to six families of some Ghanaian shield bugs, collected in Southern Ghana, west Africa are presented. Microphotographs and tracings of karyotypes observed for each species are produced as figures. Histograms of chromosome numbers of the various families have been constructed and these results together with the existing information in literature, is analyzed and discussed. In all two hundred and seventeen (217) species of...

Design Of Sun Tracker For A PV System

ABSTRACT This project involves a design of sun tracker for PV system. The circuit of the sun tracker is designed in such a way that it follows the track of the sun as it travel in the sky. The LDR are connected to noninverter input of the operational amplifier whose reference voltage resistor R1 and R2 is 10Ω each. At the output of the operational amplifier are NPN and PNP transistor. These transistors are used to drive the DC motor in forward and backward directions which corresponds to t...

Modulatory Effects Of The Crude Methanol Leaf Extract Of Cissampelos Owariensis On Some Biochemical Parameters In Bleomycin-Induced Lung Fibrosis In Male Wistar Rats

ABSTRACT Antioxidants have been shown to play protective role in the treatment of bleomycin-induced lung fibrosis. The goal of the study was to determine the effect of Cissampelos owariensis (CO) leaves, an alkaloid rich antioxidant on BLM-induced lung fibrosis in rat models. The CO (UIH22559) leaves were extracted using methanol and fractionated using vacuum liquid chromatography (VLC) to obtain the ethyl-acetate fraction (EAF) and methanol fraction (MEF). The active component of CME was de...

Decision Support System For Telecommunication Companies In Nigeria: (A Case Study Of Airtel Nigeria)
