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

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.
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.
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.
