DETERMINATION OF VISCOSITIES OF SOME SELECTED LIQUIDS USING STOKE’S METHOD

ABSTRACTViscosity is a property of a liquid and is defined as the resistance of a liquid toflow. This research is to determine the viscosities of motor oils (10w – 40w, 20w –50w), vegetable oil and honey using the fall sphere method. The viscosity of honeywith 4.44Ns/m2was found to be the highest and that of vegetable oil having a valueof 0.002861Ns/m2  is termed the lowest. The viscosities of motor oils (20W-50W )and (10W-40W) were found to be 0.00468Ns/m2  and 0.00374Ns/m2&nbs...

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...

Garlic Bulb Prevents High Blood Pressure in Egg Yolk induced Hypertensive Rats

The aim of this study is to access the antihypertensivepotential of garlic juice in rats. To achieve this, 30 Wistar ratswere divided into three groups of 10 each. Rats in groups 1 and 2received aspecial prepared egg feed diet (24 egg yolkmixed with 1kg of normal rat diet) while those in group 3 received normalfeed diet and they served as the control group. Animals in group2 were administered 3 mL/100g body weight of undiluted garlicjuice simultaneously with the feeding. The animals were fedo...

Egg Yolk induces High Blood Pressure in Wistar Rats

Hypertension constitutes a major risk factor forseveral cardiovascular diseases such asatherosclerosis, heart failure, renal insufficiency,coronary artery disease and stroke. The risk factorincreases with age in both sexes. According to WHO,about one-third of the world’s population suffersfrom hypertension and the incidence has beenincreasing at a rapid rate due to life stylemodification. This study is aimed at investigating theeffect of egg yolk on blood pressure of Wistar rats. Toachieve ...

Effect of Consumption of Garri Processed by Traditional and Instant Mechanical Methods on Lipid Profile of Wistar Rats

Aim: This study focuses on the effect of consumption of garri processed by traditional and instantmechanical methods on the lipid profile of Wistar rats.Methods: Cassava samples were obtained from the International Institute of Tropical Agriculture(IITA), Ibadan and were processed using traditional and instant mechanical methods. Fifteen adultmale Wistar rats were purchased from the Animal Holding Unit of the Department of Physiology,University of Ibadan, Nigeria with body weight between 100 ...

Air Freshener induced Oxidative Stress and Adveresly affects Immunity

Recently, the use of ‘sunlight’ air freshener in Nigeria is on the increase. Some people use airfreshener in the office, car as well as in their homes, thereby constantly being exposed to it withoutconsideration of its adverse effect on human health. This study is therefore aimed at assessing theeffect of “sunlight” air freshener on oxidative stress biomarkers. Thirty (30) Wistar rats were dividedinto three groups of ten each and kept in different rooms. Rats in group 1 were not expos...

Solving Credit Card Fraud using Ant Colony Algorithm and Artificial Neural Network

Credit card fraud has been a common theft process around the globe recently. This project looks into solving and minimizing the risk of credit card fraud using AI (Artificial Intelligence) models. 

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. In th...

Rationale for Vitamin C Treatment of COVID-19 and Other Viruses

Vitamin C and Coronavirus: Not aVaccine; Just a Humble CureCommentary by William F. Simmons and Robert G.Smith, PhDDuring the pneumonia epidemic in North Carolina in the 1940's,after American soldiers returned from the war in Europe, a small-town physician used ananti-infective protocol of intravenous vitamin C to cure 42 cases of viral pneumonia. [1]During the same period, the physician used a similar treatment to cure 60 cases of viralpoliomyelitis. All patients were clinically well within ...

Momordica foetida phytochemical screening

CHAPTER ONE1.0 INTRODUCTIONBioactive plants are commonly used by traditional healers or in folklore medicines for the relief of pain or some alignments. This act of medication has made some plant families popular (Heinrich 2000; Kuete et al., 2006).The acceptance of traditional medicine as an alternative form of health care has assistedscientists in elevating these claims, by studying the chemical composition and biological potential (Bisignano et al., 1996; Hammer et al., 1999). This has led...

On the Comparison of Some Link Functions of Binary Response Analysis Under Symmetric and Asymmetric Assumption

Binary response analysis is modeled when the response variable is nominal and as such violates the use of the ordinary linear regression model. This paper utilizes the classical approach to fit a categorical response regression model using the logit, probit. loglog and the complementary loglog (Cloglog) link functions under symmetric and asymmetric assumptions. It is captured in past studies that we can only make comparisons between these link functions when n is large say (n > 1000), In ...

On Efficient Memory-Type Control Charts for Monitoring out of Control Signals in a Process Using Diabetic Data

Control chart is a useful technique which helps in detecting out of control signal in a process and it can either be a memory-type or memory-less control chart. This work is focused on evaluating the monthly incidence of diabetic disease using four univariate memory-type control charts. In this study we evaluated the average run length (ARL) properties of the memory-type control charts by adjusting the ARL value’s determinant parameters in each control charts, and the ARL value was set to...

Modeling Monthly Average Temperature of Dhahran City of Saudi-Arabia Using Arima Models

Temperature is the coldness and hotness of the body and its unit is measured in Celsius. The data used for this research work is the average monthly temperature of Dhahran city which is located in the Kingdom of Saudi Arabia. The data range is from 1951 to 2010, and sample data of 1951 to 2008 was used for the estimation to choose the best model and the sample data from 2009 through 2010 was left for the forecast. Different models were tried but ARIMA (2, 1, 1) (0, 1, 1)12 is selected as ...

GEOLOGICAL WIRELINE LOGS AND THEIR APPLICATION

ABSTRACTWireline logging is a veritable tool for the determination of hydrocarbon beneath the subsurface, it is applied by prospecting companies hence, this work studies geological wireline logging and their application in oil and gas reservoir beneath the earth’s surface. Wireline logging is performed by lowering a logging tool of one or more instruments on the end of a wireline into an oil well and recording petro physical properties using a variety of sensors. This logging process is aid...
