A study on
the effect Moringa Oleifera leaf extract on Citrullus lanatus was carried out
at the Biological Garden of Usman Danfodiyo University, Sokoto. The aim was to
determine the effect of Moringa leaf extract at different concentration on seed
germination and early seedling growth of C. Lanatus (water Mellon). Aqueous
extract was prepared by driving freshly leaf formed Moringa leaves e water and
filtered out to obtain liquid extract which was then diluted with water in the
following concentrations: 0ml, 20ml, 40ml, 60ml, 80ml. control treatment was
set up using disliked water only. The six treatment were applied directly on C.
lanatus seeds raised in 18 poly pots of 18cm long 2cm wide. The experiment was
laid out in a completely randomize design in three (3) replicate. It was run
for 15 days. Data were collected on number of leaves, stem high, root length,
shoots fresh and dry weight at harvest, while germination rate was within 15
days of the experiment and where subjected to analysis of varience. Result obtain
showed significant (P˂ 0.05) effect of the treatment on all the
characters measured. Base on the results obtain, Moringa leaf extract has an
improving effect on seed germination and growth of C. lanatus parts farmers are
therefore recommended to adopt the use of this extract since it is easier,
inexpensive, cheaper and can be obtain in large quantities in order to meet up
demand of large hectares of land.
Several
factors are responsible for neighborhood preferences and choices ranging from
neighborhood attributes to benefits derived from it as well as personal values
of neighborhood user. As a
geographically localized community within a larger city, it is of utmost
importance for people to choose the kind of neighborhood they live therein. The
quality of the neighborhood environments and their evaluations are so
significant to the residents. These evaluations are often based on the
diversity and complexity of personal senses of looking at the neighborhood
setting as well as the varied lifestyles, personal demands, and preferences.
More often than not, the choices of a given neighborhood are motivated or
otherwise by the outcomes of the evaluations made by potential residents. The
aim of this paper is to present factors influencing residents’ choices and
preferences of neighborhood environments in Yola, Nigeria. The study was
conducted within the methodological framework of means-end chain (MEC) research
model, using the laddering interview technique. Ten respondents were
interviewed, response recorded, transcribed and content analyzed. The results
showed that several neighborhood attributes (proximity, family setup,
accessibility, quietness, terrain, and not overcrowded) are reasons for
preference and choice. Six of the Schwartz’s value domains of hedonism,
security, universalism, achievement, self-direction, and benevolence were found
to motivate these preferences and choices factors. It is important to plan
neighborhoods that will engender safety of residents, make them very happy and
give them a sense of satisfaction.
In Nigeria, Compensation valuation as a result of oil spill is undertaken based on the provision of the enabling laws and other relevant status. There are several augments as regards the factors to be considered when valuing for compensation payable as a result of oil spill. This study aimed at ascertaining the benefits of incorporating long term impact of oil spills into oil spill compensation valuation. Compensation provision of the various laws were reviewed and found to only provide assessment and payment of compensation on land, buildings, crops and economic trees, no provisions was made for the long-term impact of the spill. Consequently, both primary and secondary data were collected through questionnaires and interviews. The analysis identified the benefits as; Increase in compensation payable, improvement on already existing claims factors, increase in pipeline maintenance and surveillance and reduction in oil spill incidences. Recommendations were made and if adhered to, there is the tendency that the present inadequate compensation crisis among polluters and victims which have caused serious and lengthy litigation in the court will be reduced to the barest minimum. The researcher made the following recommendations having identified the importance of the long-term impact of oil spill in compensation determination, it is recommended that the long-term impact (value) of oil spill be incorporated into compensation valuation and the regulations governing compensation practices in Nigeria be reviewed, so as to incorporate long term impact of oil spill as an important factor in compensation determination.
A study on nutrient digestibility of Japanese quails fed
fermented mango kernel composite (FMKCM) was carried out using complete
randomized design (CRD). One hundred and ninety five (195) unsexed Japanese
quails were randomly allotted to five dietary treatments comprising of 0%, 10%,
15%, 20% and 25% inclusion levels of fermented mango kernel composite meal for
T1, T2, T3, T4 and T5 respectively.
Each treatment was replicated thrice with thirteen (13) birds per replicate.
The result of this study showed that there were no significant (P>0.05) differences
across treatments in nutrient digestibility and retention. This shows that
fermented mango kernel composite meal had no effect on nutrient digestibility.

ABSTRACT
In
view of the usefulness of chemistry to nearly all fields of human endeavor, the
poor achievement and retention of student in chemistry in college has been a
source of concern. Most of the time, poor achievement and retention are caused
by poor teaching methods used by chemistry teachers, therefore this study
examined possible ways of enhancing chemistry students’ achievement by creating
enabling learning community through activity based approach. The study employed
pretest-posttest, control group quasi experimental research design. Chemistry
achievement test (CAT) was developed by the researchers and administered to 150
chemistry student (boys and girls) in secondary school in SS2 from six (6)
randomly selected secondary schools. Data were analyzed using descriptive
statistics and the hypotheses were tested using chi-square which gave result
that there is significant difference between student exposed to ABA and those
exposed to conventional learning. Hypothesis one, t-calculated=23.605 and
t-critical=1.960 with a significance level of p<0.05, hypothesis two
t-calculated=0.623 and t-critical =1.960. Results obtained reviewed that
students perform better in chemistry when taught using ABA as compared to
conventional method. However, findings from hypothesis two reveal that gender
has no significant effect on students’ academic achievement. Analysis of the
study also found that post-test scores shows that experimental group had a mean
score of 19.25 while the control group had a mean score of 8.62, this implies
that ABA had a positive effect on the student’ academic achievement. It was
concluded that ABA is more effective than conventional learning strategy. It
was also recommended that ABA should be replicated in all science disciplines.
Ideology in
architectural practice consists of architectural ideologies or the ideas that
drive the styles and designs and the corporate ideology or the shared belief of
the principal architects that guide the running of the architectural firm.
Corporate ideologies play a significant role in strategy formulation, as an
organisations’ core ideology is essentially the ‘glue’ that holds the
organisation together. Studies have also shown that ideology has an effect on
the firms’ management structure. Ideologies can also illuminate the core values
of an organisation. Studies assert that core values are important tools of
measurement when determining if organisational approaches are viable. Firm
ideology as a component of firm culture is, by implication a critical factor
for determining viability of the firm. The objectives include identifying the
prevalent ideologies in architectural firms in North Central Nigeria, relating
the ideologies to viable and sustainable architectural practice in Nigeria. The
sample was derived from firms in the Architects Registration Council of Nigeria
(ARCON) Register, purposively selecting cities where architectural firms were
most concentrated in North Central Nigeria. The principal survey instrument was
a structured questionnaire, and a total of one hundred and two (102) questionnaires
were collated and analysed. Data from the questionnaires were also analysed
using Pearson’s product-moment correlation coefficient, and regression
analysis. Results of the study revealed most firms intuitively operated with
architectural practice ideologies which significantly enhanced viability. These
findings have created awareness that while Nigerian architecture practice does
not show commitment to ideology, ideologies exist.

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.
