THE ISOLATION OF GUM FROM DELONIX REGIA, ITS MODIFICATION USING BORAX (DISODIUMTETRABORATE DECAHYDRATE) AND ITS CHARACTERIZATION

Delonix regia popularly known as the flamboyant plant because of its onyx attractive color has been generally cultivated in the tropics. Although it was widely cultivated in the 19th century, yet the native habitat of the flamboyant tree was unknown until the 1930s, when it was retraced to native growing in the wild in Madagascar. The uses of Delonix regia as binders in drugs, adhesives, stabilizers, etc. have been some of its numerous applications in the field of science and biomedicine and ...

EVALUATION OF DELTAMETHRIN ON SITOPHILUS ZEAMAIS

ABSTRACTLaboratory 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 the ...

THE MATHEMATICAL MODELLING CONCEPT pt1

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 ...

Effect of Emilia Sonchifolia on Globulin and Bilirubin level of Winter rat

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 Sonchifol...

THE POSITIVE AND NEGATIVE IMPACTS OF ICT

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 loo...

Discrete time mathematical SIR model for disease transmission

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  ...

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 is...

DESIGN AND IMPLEMENTATION OF MOBILE ONE-TIME PASSWORD AND RIVEST CIPHER FOUR ENCRYPTION FOR CLOUD COMPUTING SECURITY

ABSTRACTThe use of cloud computing in recent times has recorded remarkable growth while securityand privacy issues have remained a critical challenge and a thing of concern forresearchers. The reason partly is associated to the fact that most users do not have baselineknowledge 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 theDesign and Implementation of Mobile One-Time Password an...

Codigestion of Oryza sativa Husks and Musa paradisiaca Peels for the Production of Biogas

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...

NoSql data collection on comparative analysis of Archaea economic importance and other domain of life

verviewStatsCommentsCitationsReferences (29)Related research (10+)AbstractEnvironmental investigations show that the Archaea are diverse and abundant not only in extreme environments, but also in soil, oceans and freshwater, where they may exhbit a key function in the biogeochemical cycles of the planet. 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 E...

Kinetic studies of the biosorption of lead and zinc from solution using tea fibre

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. Kine...

FERTILITY ENHANCING POTENTIAL AND METABOLIC EFFECT OF ETHANOLIC ROOT EXTRACT OF SPHENOCENTRUM JOLLYANUM IN MALE WISTAR RATS

CHAPTER ONE1.0    INTRODUCTIONProcreation 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, ...

The Security Implications of Virtual Local Area Network VLAN Niger Mills Calabar Nigeria

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 b...
