electric power in Nigeria; a key input to the effective development of this nation. At present, the
generation of power, the upstream sector of the electrical power industry, is beset with
challenges and difficulties, which can be met with a synergy of natural gas and other options.
This paper presents an effective optimization of power synergy; the key to unlocking unlimited
megawatts of electricity for Nigeria. This will be enhanced through best practices,
innovativeness and a free market system.

ABSTRACT: By virtue of the vital nature of electric power, both to our economic and personal
well being, a power system is expected to supply electrical energy as economically as possible,
and with a high degree of quality and reliability. The developing countries in general place
higher reliability standard on the performance of electricity supply. However, there has been no
significant study in the context of the Nigeria power sector to power system simulation model
based on probability analysis the technical appraisal of the state power systems in general is
confined to examining the Plant Load Factor (PLF) as a measure of capacity utilization only.
The present study is a modest attempt to evaluate the reliability of the Nigeria power system in
the framework of a theory-informed methodology power system simulation model based on
probability analysis.

ABSTRACT: A copolymer from propylene and methyl acrylate would produce an alternating
copolymer of highly desirable properties for paint and allied chemical industries; indicative of
the properties of the individual homopolymers. In this work, a kinetic model was developed for
the copolymerization of propylene and methyl acrylate. A radical initiator was used for the
initiation to form a couple and subsequent propagation steps presented. Transfer specie used for
the termination step. The various rate expressions and subsequent kinetic models were
presented, thereby showing the relationship between various polymerization parameters with
time. Such parameters includes: concentration of initiator, concentration of growing polymer
chain and concentration of dead polymer chain. The models developed will prove invaluable if
annexed in the design, control and optimization of the polymer production process.

ABSTRACT
The study examined the effects of oil exploration and exploitation
activities on food production and the health of the inhabitants of
Oloibiri environ in Bayelsa State. Two objectives and two hypotheses
were generated. The hypotheses were tested at 0.5 significant level of
probability. A sample of 390 people from three communities were
randomly selected. The data-set were selected using the effects of oil
exploration activities on human health and food production determinant
questionnaire (EDEHFO), designed and used to elicit the data for the
study. The one-way analysis of variance (ANOVA) was used for the data
analysis with the aid of the statistical package for social sciences
(SPSS). The results based on the first hypotheses which states that
there is a significant difference in food production resulting from oil
exploration and exploitation activities are accepted. Since F-cal (0.25)
< F-Crit (3.00) at 2 and 689 degree of freedom at 0.05 level of
significance – by and large the results indicates a negative impact on
the environment of the study area.

ABSTRACT: This paper evaluated the tensile strength and hardness of AISI 304 stainless
steel heat treated to temperatures of 400oC, 600oC and 800oC and soaking durations of 30
minutes, 2 hours, 12 hours, 24 hours and 72 hours in each temperature level. The tensile
strength was measured using Automated Ball Indentation (ABI) technique while the hardness
was on the Brinell scale. To establish confidence in the ABI technique, values obtained were
compared with similar studies conducted with the conventional tensile measurement tool. The
tensile and hardness properties of type 304 SS increased with treatment temperatures of
400oC and 600oC for all the holding durations up to 72 hours. The long stay was akin to work
hardening which increased the tensile strength. The cooling in hot sand bed may have
equally contributed to increased surface hardness measured. At temperature of 600oC,
precipitation of chromium carbides along grain boundaries coupled with a dense formation
of sigma phase and other phases like the chi combined to influence the tensile strength.
Temperature of 800oC and soaking duration beyond 30 minutes produced decreased tensile
and hardness properties in the steel. At this temperature, transformation of the steel grains by
re-crystallisation and relief of internal stresses occurred. The extended soaking duration of
72 hours led to increase of Cr diffusion to the surface.

ABSTRACT
Intestinal parasitosis remains an important public health problem in
underdeveloped and developing countries. Intestinal nematode parasites
comprise an important group of human endoparasites that infect mostly
school age children. This research was carried out to determine the
prevalence of intestinal nematode parasites (INP) in children attending
two primary schools in Mbaitoli Local Government Area, Imo State,
South-Eastern Nigeria. Two hundred feacal samples from 200 school
children were examined using direct smear. The overall infected
samples were 85(42.50%), comprising 43(21.50%) females and
42(21.00%) males. Three intestinal nematode parasite species were
indentified: Ascaris lumbricoides, Trichuris trichiura and hookworm.
When ranked by proportion, parasite loads were found as follows:
Ascaris lumbricoides (67.06%), hookworm (27.06%) and Trichuris
trichiura (21.18%). Statistical analysis indicates a significant difference
(p>0.05) in prevalence of the parasites with Ascaris lumbricoides having
the highest rate of prevalence. There were single and double infections
in the study. We conclude that there is a pronounced intestinal
nematode parasitic burden amongst school children in Mbaitoli Local
Government Area, Imo State, Nigeria. Therefore, regular de-worming
exercise with appropriate antihelminthes, education on personal hygiene
and other health campaign programmes if carried out in the rural areas
will improve the health status of school children.

ABSTRACT
Spawning pattern of Nematopalemon hastatus in River Nun Estuary,
Bayelsa State in the Niger Delta was studied for one year. Samples
were collected from artisanal shrimpers operating along the estuary on
a monthly basis and stored in 9% formalin for laboratory analysis. The
N. hastatus in each monthly sample were observed for gravity, using a
hand lens. There was a colour change in the eggs from light orange to
dark brown with maturation. Eggs in different stages of maturation
from light orange to dark brown were observed in the samples all year
round, comprising both rainy and dry seasons. Main spawning observed
was between July and September. The peak spawning activity occurred
in September while the lowest was between November and December.
Largest satus with eggs measured 14mmCL (carapace length) and the
smallest 7mmCL. Statistical analysis to test the level significance of
gravid N. hastatus between seasons showed that more spawners were
landed during the rainy season than the dry season. Spawners are
usually caught before they have the chance to lay their eggs and this
could lead to a reduction in the reproductive process, resulting in a
decrease in biomass. It is therefore pertinent to introduce management
strategies involving, fisheries scientist, fisheries managers and the
shrimpers.

ABSTRACT
Different control measures have been targeted against vectors of
diseases, and attempts relied heavily on the use of such synthetic
pesticides. Unfortunately, the repeated use of synthetic insecticides
has disrupted natural biological control system. The development of
resistance and human health concerns has led to a search for
alternative control measures. To test the toxicity of the ethanol
extract of Moringa oleifera seed oil on Simulium larvae, larvae of
Simulium were used for larvicidal bioassay. 120 larvae were released in
plastic containers. 20 for every set of experiment, with two replicates
for each concentration of Moringa oleifera seed oil. 200ml of water was
used, after which the oil extract was introduced. A total of 100%
mortality was recorded in 0.1ml and 0.2ml treatment levels, showing an
excellent toxicity on the larvae sampled. The result of this study
suggests that the plant extract can act as larvicide against Simulium
larvae in breeding sites.

ABSTRACT
This paper describes the phytochemical and antifungal studies of two
members of the Capparidaceae family which are Gynandropsis
gynandra and Buchholzia coriacea. These two plants were screened for
the presence of their active constituents. The leaves and the stem
were screened separately. The antifungal activities of the leaves and
stem were tested using Aspergillus niger, Penicillum sp., Candida
albicans, Fusarium oxysporium and Aspergillus flavus. The activity of
the extract at 200mg/100ml (0.02g/10ml) of methanol was compared
with methanol as the control and Tioconazole as reference standard.
The result of the antifungal assay of the plant extracts justifies
their use in traditional medicine.
