ABSTRACT

Nigerians are experiencing a lot of difficulties as a result of poor Generation, Transmission and Distribution of electricity. As of 2016, the electricity energy consumption in the world from the world fact book revealed that the average power per capital (watts per person) in the United States is 1,377 Watts. In Canada, it is as high as 1,704 Watts per person and in South Africa; it is 445 Watts per person. The average power per capital in Australia is 1,112 Watts and in New Zealand it is 1,020 W per person. Whereas, the average electricity consumed in watts per person in Nigeria is just 14 Watts.  This has put Nigeria in a rank of 189 out of 219 countries estimated. 

Currently, power generating capacity in Nigeria is estimated to be 6,803 megawatts, with average working capacity between 3,500 MW for over 170 million people (20.59 W/person). The power Companies in Nigeria face a lot of problems. Some of the highest priority issues being low generation of power, inadequate equipment and technical team for the clearance of faults, inadequate protection devices, transmission losses and low reliability of the distribution system. The Nigerian power problem has resulted to incessant planned, forced and unplanned outages. This has grounded many activities and has destroyed many industrial operations and processes. In addition, it has resulted to erratic and unreliable supply of electricity. It has reduced productivity and has increased unemployment and crime rates in the country. Hence, an analytical method is developed to study the dynamic- reliability of the distribution system, as well as optimizes the occurrence of faults and outages along the consumer point in each feeder in order to improve the performance of the system. A great need for fault evaluation and reliability studies of electric power system was observed. This research work analyzed the problems facing the Distribution System. Efforts were made to provide adequate solutions to the problems. The research work evaluated the occurrence and causes of faults and outages in the Distribution Network Area for a period of 8 years. In addition, it analyzed and reduced the effects of power losses along each of the feeders in the Distribution Network Area. This research work revealed the downtime, failure rate and reliability index along each of the eight feeders. It also improved the reliability and performance of the distribution system

ABSTRACT

Entrepreneurship involves identification and creation of a previously unexploited opportunities followed by will and initiative to seize these opportunities. The classical model of entrepreneurship involves creation of new venture, but modern entrepreneurial approaches are also an integral part of establishing corporate academics and government organizations. Polymer materials can be found everywhere nowadays, such as plastic water and beverages bottles, the silicon rubber tips on your phone, the nylon and polyesters in your jacket or sneakers, plastic hospital and domestic waste among others are all polymers. This paper tends to review the entrepreneurial opportunity from recycling of these waste plastic materials. The plastics materials can be recycled and reuse as packaging materials ranging for local soft drinks makers such as Sobo and ginger. Similarly different source of energy can be generated from these waste plastics ranging from solid briquettes, liquid fuels as well as combustible gaseous fuels. Therefore, these techniques such as recycling, reuse and energy generation from these waste materials can provide many entrepreneurial opportunities to teaming chemistry graduates as well as wealth creation, thus improving revenue generation to the nation entirely. Polymer recycling technique is also an amiable in reducing environmental problems caused by these polymeric waste accumulations on daily basis. It will also help in conserving our natural resources being from petrochemicals.

ABSTRACT

In this study we, developed and analysed a deterministic model for the transmission dynamics and control of Gonorrhea. Three nonlinear ordinary differential equations were used to describe this spread. The equilibrium points of the model are found and their stabilities are investigated. The basic reproduction number  was also calculated. The model exhibits two equilibria namely the disease free equilibrium in which all infected compartments are zero and the endemic equilibrium in which all the compartments are greater than zero. It was found that for, the Disease Free Equilibrium is locally asymptotically stable and unstable if otherwise.

Keywords: Stability, Disease Free Equilibrium, Gonorrhea,Basic reproduction number.

ABSTRACT

Vital sign component in human life is very significant for healthy growth. The main objective of this research work is to determine the relationship between vital sign component and its consequence as well as to demonstrate the use of statistical methods in medicine to figure out the efficiency of the model. The result reveals that logistic and inverse models perform better than other models under the studies and that pulse response and age are vital signs components in human health.
