ABSTRACT Laboratory experiments were conducted to evaluate the effects of deltamethrin dust as a protectant of maize against Sitophilus zeamais under ambient laboratory conditions of 27 ± 3°C and 70 ± 5% relative humidity. Four sets of fifty grams of disinfested maize grains were measured into jars in four replicates. Each replicate was infested with ten 0-7days old adult S.zeamais. Each set of three replicates were treated separately with 0.25g, 0.187g and 0.125g of deltamethrin while th...
The mathematical equations and concepts we learned in schools can actually be summed up to be relevant in the prediction, estimation and understanding of certain real world situations or problems that surrounds us. Some examples could be, How can we predict the break of a new infectious disease affecting the country Nigeria? How can reduction in the import of items into the country Nigeria affect the long term economy of the country Nigeria? How can we apply certain mathematical concept in ...
ABSTRACT The place of adequate nutrition in the live of the young especially in the recently weaned cannot be overemphasized. The abrupt change in diet, leading to possible immune system weakness and disease conditions, is a focal point in the care of the young. This project examined serum globulin and bilirubin levels in weanling rats whose feed was supplemented with Emilia sonchifolia leaf extract.Present investigation were carried out on the effect of ethanolic extract of Emilia Sonchifo...
As it is known from time immemorial that everything in life is like the two side of a coin, there is always a positive and negative side of every phenomenon. But whether the effect is positive or negative the effects of Information Communication Technology (ICT) is far reaching and cannot be overemphasized. The Effects of ICT lens looks at how our lives have been changed, for better and for worse, by the impact of ICT. It includes both positive effects and negative effects and looks at how ...
ABSTRACT: Infectious disease has become a source of fear and superstition since the first ages of human civilization. In this study, we consider the Discrete SIR model for disease transmission to explain the use of this model and also show significant explanation as regard the model. We discuss the mathematics behind the model and various tools for judging effectiveness of policies ...
Information Technology has revolutionized the way we go about doing our daily activities. The web for instance has revolutionized the way information can be accessed thereby making the world a global village. The impact of information technology has grown to the level that virtually all domains of life now has everything in Electronic. Now we have E-Commerce, E-Examination, E-Voting, E-Registration. The availability and deployment of all of these is made possible with the use of the Intern...
A Students Web Based Course Registration System is a subsection of the Management Information System (MIS) that obtains its input from the transaction processing system; a subsection of the Business Information System (BIS). Business Information System (BIS) is the base of a Management Information System in any institution with the sole aim of integrating human, business and technology together in order to achieve efficiency in the execution of duties, thus the MIS provides information that i...
ABSTRACT The use of cloud computing in recent times has recorded remarkable growth while security and privacy issues have remained a critical challenge and a thing of concern for researchers. The reason partly is associated to the fact that most users do not have baseline knowledge of how to securely use cloud services and as such they end up becoming victims, because hackers take advantage of their inadequate knowledge. This thesis is on the Design and Implementation of Mobile One-Time Passw...
Oryza sativa husks and peels of Musa paradisiaca were pretreated by hydrothermal and acid fermentation using cassava mill effluent, and co-digested in a laboratory scale reactor maintained at 45 ± 2 ⁰C for 42 days. Five digesters were used for the experiment and each digester contained equal proportion of Oryza sativa husks and Musa paradisiaca in the ratio of 1:1; and cow dung (the inoculum) was added across. Substrate in Digester X (Control) was not pretreated. Digester A contained Oryza...

Archaea display unique capacities, such as methanogenesis and survival at temperatures higher than 90 °C that make them crucial for understanding the nature of the biota of early Earth. M...
Abstract: This paper presents a biobsorption study on Zn and Pb(II) from dilute aqueous solution using tea fiber as the biosorbent. The biosorption study was carried out as a function of contact time, initial metal ion concentration and biosorbent dosage. The residual Zn and Pb(II) in solution were determined using atomic absorption spectrophotometer. The biosorption was also time dependent as maximum biosorption was obtained after 10 and 20 min, for both lead and zinc respectively....
CHAPTER ONE 1.0 INTRODUCTION Procreation is an important moral and religious issue and aphrodisiacs are sought to ensure both male and female potency. Sexual potency is part of the male ego, the anxiety and the humiliation that are associated with a declining sexual ability are common to all cultures. That is why the popularity of aphrodisiacs has not shown any sign of decline throughout history. Successful treatment of sexual dysfunction may improve not only sexual relationships, but al...
The overall objective of this study is to scientifically evaluate the claimed fertility enhancing potential and to assess the metabolic effect of the ethanolic extract of Sphenocentrum jollyanum pierre (Menispermaceae) root using male wistar rats as model. The specific objectives include the following · To determine the proximate and phytochemical composition of the ethanolic extract of Sphenocentrum jollyanum (root) this will justify the ethno pharmacological use of th...
Virtual local area network (VLAN), is a logical grouping of network users and resources connected to administratively define the operation of activated ports on a switch. The creation of VLAN is saddled with the ability to develop smaller broadcast domain within a layer-2 switching router; by assigning different ports on the switch to different sub networks. The application was a re-design project carried out on the Niger-Mills’ network to improve the operational short falls identified by t...
— Investigations have shown that interior places of the nation lacked capacity for high speed Internet usage; except the cosmopolitan sections. This article, therefore, conceptualizes a robust Broadband roadmap that can effectively deliver IP-wholesale and IP-retail services, through traffic convergence. The interconnect platforms are designed to ensure automatic re-routing of broadband traffic during link or node failure. The IP-wholesale services can be delivered to all main cities in Nig...
