TUNGIASIS: A NEGLECTED TROPICAL DISEASE

ABSTRACT Tungiasis is an ecto-parasitic disease of humans and animals caused by the burrowing of gravid female fleas of the genus ‘Tunga’. Of the known species of Tunga fleas, Tunga penetrans and Tunga trimamillata are parasites of humans besides other warm blooded mammals, most of which are peri-domestic. The host of the others is limited to a few genera of wild mammals. The burrowed female flea rapidly expands its body size, causing immense itching, inflammation, pain a...

On mathematical models for pension fund optimal selection strategies

Pension, being regular payments made to retirees or their beneficiaries after retiring from active service, needs efficient and effective management because of the funds involved as the living standard of the retirees and their dependants rest on it after retirement. In attempt to maximize the wealth of pension contributors, the investors may end up losing the pension fund assets because higher returns on investment go hand in hand with higher risk of loss of invested contributions/savi...

COMPARATIVE STUDIES OF THE BIOSORPTION OF HEAVY METALS ( LEAD & ZINC) USING TEA LEAVES (CAMELIA SINENSIS) & TEA FIBRE AS ADSORBENT

Abstract: This research has helped us to ascend from the initial two exploratory studies to a more advanced general conclusion and theory that tea leaves (Camellia sinensis) has a great potential for Pb(ii) and Zn uptake, as such, a more suitable Low-cost adsorbent for the effective removal of Pb (II) and Zn from industrial effluents waste water than tea fibre. This is coined from the results of the different biosorption studies carried out as a function of contact time, initial metal ion...

EFFECT OF CELLGEVITY ON CATALASE ACTIVITY OF RAT MODEL OF PARKINSON DISEASE

Parkinson’s disease is a degenerative neurological disease, which is characterized by the preferential death of dopaminergic neurons in the Substantia Nigra. Current drug treatments are aimed primarily for the treatment of symptoms to improve the quality of life. Therefore, there is a need to find out new therapeutic strategies that not only provide relief but also halt or reverse the neuronal damage hampering PD progression, thus this research therefore aimed at investigating th...

A STUDY OF THE PHYTOCHEMICAL CONSTITUENTS, NUTRITIVE AND ANTI-NUTRITIVE VALUES OF CALABASH FRUIT

The calabash (Cresentia cujete) fruit was studied for its proximate and mineral composition as well as its phytochemical constituents.  The sugar content, energy content, protein, nitrogen, crude fibre, moisture content, sucrose, fructose, galactose and energy content are quite reasonably high (viz: 1.13%, 8.35%, 1.34%,  4.28%,  84.92%,  59.86%,  25.09%, 18.24% and 88.69%). The pH of the fruit falls within the acidic range (4.8) and the mean value recorded for the ele...

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  ...

Design of an Online Tutorial System

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 Internet...

Design and Implementation of a Web Based Course Registration System

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...
