1. An analysis of the prevalence of HIV and AIDS at General Hospital Minna using canonical correlation analysis

Chapter One 1.0 General Introduction
Ever since the identification of Human immunodeficiency virus (HIV) as the cause of Acquired Immune Deficiency Syndrome (AIDS) in 1983, the infection has become a global epidemic. HIV/AIDS is a unique and complex crisis that requires immediate attention and long-term solutions. Tumer and Unal (2000) argue that HIV/AIDS is a highly intricate health issue of the 21st century. Despite the significant efforts made in terms of funding,...

2. SOCIETAL AND PUBLIC HEALTH MEASURES AGAINST THE EFFECTS OF SARS-COV-2 ON THE TRANSMISSION DYNAMICS OF MALARIA: A MATHEMATICAL MODELLING APPROACH

INTRODUCTION: Human beings are at constant risk of infectious diseases. No human can be exempted from the menace of epidemic disease (Ademola and Odeniran 2016) . The continuous reports from emerging and re-emerging infectious diseases remain a global concern. Transmission mecha-nisms of epidemic disease can only be properly understood by developing potent prophylactic tools for existing and emerging organisms (CDC 2019). Micro-organisms are usually the main causes of infectious diseases, dep...

3. A THEORETICALLY LOSSLESS METHOD FOR DERIVING EMPIRICAL ORTHOGONAL FUNCTIONS FROM UNEVENLY SAMPLED DATA

ABSTRACT

The Lomb-Scargle discrete Fourier transform (LSDFT) is a fairly popular technique for analyzing time series within the astronomy community. However, this algorithm is largely unknown in many other disciplines, despite many potential applications. In particular, the atmospheric sciences stand to benefit substantially from implementing it, since much of the corpus of observational data is irregularly sampled. In this study, a solution for empirical orthogonal functions (EOFs)...

4. APPLICATION OF ECONOMIC ORDER QUANTITY MODEL FOR THE PURCHASE AND GROWTH OF ORGANIC POULTRY WITH INCREMENTAL QUANTITY DISCOUNTS

ABSTRACT

The purpose of the study is to develop a lot sizing model for growing chickens if the supplier of the products offers incremental quantity discounts. A mathematical model was derived to determine the Optimal Inventory Policy which minimizes the total inventory cost in both the owned and rented facilities. A solution procedure for solving the model is developed and illustrated through a numerical example. Sensitivity Analysis was performed to demonstrate the response of the...

5. COMBINATORIAL PROPERTIES OF THE ALTERNATING & DIHEDRAL GROUPS AND HOMOMORPHIC IMAGES OF FIBONACCI GROUPS

Abstract

be a finite n -element set and let

Sn , An

and Dn

be the

Symmetric, Alternating and Dihedral groups of

X n , respectively. In this thesis we

obtained and discussed formulae for the number of even and odd permutations (of an n - element set) having exactly k fixed points in the alternating group and the generating functions for the fixed points. Further, we give two different proofs of the

number of even a...

6. DETERMINATION OF THE NUMBER OF NON-ABELIAN ISOMORPHIC TYPES OF CERTAIN FINITE GROUPS

Abstract

The first part of this work established, with examples, the fact that there are more than one non-abelian isomorphic types of groups of order n = sp, (s,p) = 1, where s<p and p º 1 (mod s) for 100 < p < 4000. The factors s and p are distinct primes. Specifically considered here are groups of order n = 2p, 3p, 5p, 7p, 11p and 13p. It was discovered that the number of non-abelian isomorphic types of groups of order n = sp, s<p increased as n increased. The de...

7. DETERMINATION OF THE EFFECT OF EXTRACTED OXYGEN HETEROCYCLE ON THE DEHYDROCHLORINATION OF VI NYLIDENE CHLORIDE COPOLYMER

1.1Background of study

Vinylidine chloride, also referred to as 1,1-dichloroethylene (1,1-DCE) is a colourless liquid (b.p.  32.2qC),  produced  by  dehydrochlorination  of  1,1,2  ±trichloroethane  [Cl2CH CH2Cl],  a relatively  unwanted  by-product  formed  in  the  production  of  1,1,1±trichloroethane  and  1,2± dichloroethane. Conversion to 1,1±DCE involves...

8. DEVELOPMENT OF FALKNER-TYPE METHOD FOR NUMERICAL SOLUTION OF SECOND ORDER INITIAL VALUE PROBLEMS IN ORDINARY DIFFERENTIAL EQUATIONS

ABSTRACT

This research focuses on the formulation of block hybrid methods with power series as basic function through interpolation and collocation techniques for numerical solution of second order initial value problems in ordinary differential equations. The step number for the derived block hybrid method is k=2 with two off-step point and four off- step points. The basic properties of numerical methods were analyzed and findings revealed that the methods were consistent, zero-sta...

9. EFFECTS OF MNEMONIC AND PRIOR KNOWLEDGE-BASED INSTRUCTIONAL STRATEGIES ON SENIOR SECONDARY SCHOOL STUDENTS’ LEARNING OUTCOMES IN MATHEMATICS IN IBADAN

ABSTRACT

Mathematics is the bedrock of scientific, technological and national development. Despite the importance of Mathematics, poor performance of students in the subject still persists at the secondary school level. The problem has been attributed to several factors which include non- utilisation of instructional strategies that make use of student’s prior knowledge and memory such as the Mnemonic and Prior knowledge-based instructional strategies. Studies have shown that...

10. IMPACT OF INQUIRY AND PROBLEM - SOLVING STRATEGIES ON ATTITUDE, RETENTION, AND PERFORMANCE IN TRIGONOMETRY AMONG SENIOR SECONDARY SCHOOL STUDENTS’ IN ZAMFARA STATE, NIGERIA

ABSTRACT

This study investigated the impact of inquiry and problem-solving Strategies on Attitude, Retention and Performance in Trigonometry among Senior Secondary School Students in Zamfara State, Nigeria. A Quasi-experimental research design with pretest-posttest control group design was adopted. The study used senior secondary school two (SSII) students with population of 23,910 admitted during 2015/2016 academic session in Zamfara state. A Multi-stage sampling procedure was used...
