As all schools are forced to close to curb the spread of this virus, students are at home, saving the world, trying and putting things in places. Executive of Social Sciences Students' Association (SOSSA), Ekiti State University chapter duly led by Hon. Comr. A...

Christoffel symbols

An overview of Christoffel symbols and covariant derivative 

Pagano's theorem. A generalized form of the Dirichlet integral involving Laplace Transforms techniques

The problem of integration technique over integrands of the form f(t)/t^n, can be solved by differentiation(n times)  by using Leibniz's rule to get rid of t^n, that leads to integrate back (n times) to end the game which it's harder than the original problem.This work focuses on the derivation of the formula (Pagano's Theorem) which is a perfect tool to avoid that hard task. It allows to change the difficult n iterated integrals  into a more outstanding easier problem which consists of n -...

Laplace Transform application in Control System

Abstract: An introduction to Laplace Transform is the topic of this  paper. It deals with what Laplace Transform is, and what is it actually used for. The definition  of  Laplace  Transform  and  most  of  its  important  properties  have been  mentioned  with  detailed  proofs.  This  paper  also  includes  a  brief overview  of  Inverse  Laplace  Transform  as  well  as  a  brief  overview  of application  in  control  system.  A  few  practical  life�...

Application of Water Quality Index in the Drinking Water Quality Assessment of a Southeastern Nigeria River

Abstract: The physico-chemical parameters of Ikwu River were studied between January and June 2016 in 3 stations to assess its drinking water quality using water quality index. Weighted arithmetic water quality index (WAWQI) method was used. Thirteen parameters were evaluated which included temperature, pH, electrical conductivity (EC), dissolved oxygen, total dissolved solid (TDS), chemical oxygen demand (COD), nitrate, alkalinity, phosphate, sulphate, chloride and calcium. The physico-c...

Intravenous Ascorbic Acid (IVAA) for COVID-19 Supportive Treatment in Hospitalized COVID-19 Patients (Based on use in China and US settings)

Abstract:  Intravenous ascorbic acid (IVAA) is a well-known intervention in medicine, which currently is rarely used  in US hospitals. Due to the unusual and extreme clinical demands of hospitalized COVID-19 patients, IVAA has been implemented in Chinese hospitals, and data published by the “Expert Group on Clinical  Treatment of New Corona Virus Disease in Shanghai” (direct translation) details the use of IVAA as safe  and effective adjunctive care of hospitalized COVID-19 patients. ...

A Philosophical Appraisal of the Politics and Economics of Food in Africa

The continent of Africa has recorded impressive economic growth for over two decades. Factors identified as contributing to this growth include commercial oil deposits, inflation control, government liberalization and privatization policies, foreign direct investment, private sector investment in industries such as construction and service sectors, and a strong agricultural production. The continent is likely to continue enjoying strong economic growth if these resources are well managed. Afr...

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/savings. T...

AN INVESTIGATION INTO THE EFFECT OF FLOOD ON RADIOACTIVITY LEVEL OF WATER SEDIMENT IN MAKURDI RIVER BENUE STATE

In this work, the radiation monitor 4/4EC was used to measure radiations. The radiations in seven different locations were monitored and measured. The mean of all the readings were taken and subtracted from the background radiation and the radiological survey of the Makurdi River at seven different locations showed no gamma, beta and alpha measurements above typical background levels (5 to 25 at random intervals). The expected dose equivalence of the samples are within acceptable dose limits ...

Effect of Leaf-Type on the Nutritive and Organoleptic Properties of Ogiri-Egusi (Fermented Citrullus vulgaris) Seeds

ABSTRACT---- The effect of wrapping type on the nutritive and organoleptic properties of Ogiri-egusi (fermented Citrullus vulgaris) seeds was studied. The leaves used were miracle fruit leaves (Thaumatococcus danellii), cocoyam leaves (Colocasia spp), and banana leaves (Musa sapientum). The melon seeds were hulled, sorted and washed, boiled for 4h, ground and then wrapped in small portions in different leaf-types and fermented for five days. Proximate analysis and sensory evaluation were...
