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. ...

Momordica foetida phytochemical screening

CHAPTER ONE 1.0 INTRODUCTION Bioactive 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 assisted scientists in elevating these claims, by studying the chemical composition and biological potential (Bisignano et al., 1996; Hammer et al., 1999). This ...

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...

GEOLOGICAL WIRELINE LOGS AND THEIR APPLICATION

ABSTRACT Wireline 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 ai...

Background: The use of household insecticides for the eradication of insects especiallymosquitoes in Nigeria is increasing. These insecticides are used without consideration of theiradverse effect on human health.Aim: This study is therefore sought to investigate the effect of common household insecticidesused in Nigeria on oxidative stress biomarkers.Methodology: Thirty (30) male Wistar rats were divided into five groups of six (6) each. Rats ingroup 1 were exposed to Rambo, those in group 2...

Chemical Content and Antioxidant Potential of Aqueous Extract of Irish Potato Tubers Traditionally Used for Ulcer Treatment in Nigeria

Aim: The study evaluated the chemical contents and antioxidant potential of aqueous extract of Irishpotato tubers traditionally used for ulcer treatment in Nigeria.Methods: Freshly harvested Irish potato tubers were purchased from Aba grocery market, AbiaState. They were thoroughly washed in running water, peeled, sliced and dried in an oven at 60ºC toa constant weight. The dried potatoes were milled into fine powder (flour) and extracted using wateras the solvent. The proximate, mineral, ph...

Bigi Soft Drinks might Induce Hyperglycemia and Hyperlipidemia in Wistar Rats

Background: Bigi soft drinks are carbonated drinks produced by Rite Foods Limited. Thecompany is an indigenous company in Nigeria. Before 2016, Coca-cola bottling company and 7upbottling company products were the dominant soft drinks in Nigeria.
