Antimicrobial and pharmaceutical properties of Khaya senegalensis seed oil
(2006-01-26) Jennifer D. Audu-Peter; , Patrick O. Olorunfemi; Ngozi Njokú
The fruits of Khaya senegalensis plant, family Meliaceae, were collected early in the year and appropriately
identified. The seed oil was extracted just before the rains came in the month of March using traditional methods of
extraction of the Higgi (Kamue) people in Michika L.G.A., Adamawa State of Nigeria. The seeds were removed
from the fruits and dried under sunlight until crisp and then roasted on earthenware pot, pounded to a smooth paste
in a wooden mortar and pestle mixed with water (pH 8) and boiled for about 3 hours. The oil settling on top was
skimmed off and heated to remove excess water and then filtered. The oil was subjected to antibacterial and anti
fungal testing, then formulated into a lotion and subjected to stability testing. The oil was found to possess some
activity against Staphylococcus aureus and Pseudomonas aeruginosa. The oil has potential as a cosmetic product
due to its easy emulsification, good spreadability, consistency, emollient property and being easily washed off from
the skin.
Accumulation of Polychlorinated Biphenyls (PCBS) in Soil and Water from Electrical Transformers Installation Sites in Selected Locations in Jos Metropolis, Plateau State, Nigeria
(Journal of Environmental & Analytical Toxicology, 2018-04-15) Ibrahim et al.,; Gushit, JS2,; Salami,SJ2; Dalen, MB2
Soil and water samples from surroundings of selected Electricity Transformer installations belonging to the Jos
Electricity Distribution (JED) Plc, Jos were analyzed for different congeners of polychlorinated biphenyls (PCBs)
widely used as coolants. The EPA 3550 and 3510 methods were used for the sampling, preparation and extraction
of the soil and water samples respectively. The extracts were cleaned up using column chromatography packed with
silica gel (120 mesh). Thereafter, it was concentrated for characterization and quantification using Gas
Chromatography coupled with Mass Spectroscopy Detector (GC-MSD). Fifteen (15) congeners were identified and
quantified in the soil samples. The result obtained shows C52 to have the highest concentration with the value of
5.84 mg/kg. The range for the concentrations of the various congeners identified are: C18 (0.00-0.05 mg/kg), C20
(0.27-0.70 mg/kg), C28 (0.28-0.39 mg/kg), C29 (0.28-0.39 mg/kg), C44 (0.15-0.54 mg/kg), C52 (0.09-5.84 mg/kg),
C101 (0.38-0.51 mg/kg), C137 (0. 45-1.79 mg/kg), C142 (0.00-0.55 mg/kg), C153 (0.37-1.20 mg/kg), C170 (0.15-1.59
mg/kg), C180 (0.00-0.47 mg/kg) and C194 (0.00-0.32 mg/kg). Similarly, for the water samples only C20, C28, C29, C101,
C105 and C153 were identified and quantified. The result shows C153 having the highest concentration with the value
of 0.57 mg/l followed by C105 (0.48 mg/l), C101 (0.37 mg/l), C28 and C29 have same concentration of 0.28 mg/l. From
thirty samples analyzed, the result of the soils is below the Canadian Reference maximum allowable limit while that
of water has some values higher than the recommended allowable limit. The studies showed various concentrations
are link with ages of Transformer installation, as those installed earlier had more congeners with higher
concentrations than the recent ones
Emerging Challenges in Nigerian Teaching Profession: Way Forward
(2017-03) Oke, Tolutope Idowu (Ph. D); Ogundele, Michael Olanrewaju (Ph.D); Mainoma, Hauwa’u Muhammad (Ph.D)
The paper examined the emerging challenges in Nigerian Teaching profession and way forward. The issues relating to the
Teaching Professions, Concepts and the features of a Profession as compare to the teaching in Nigeria are also discussed.
The Emerging challenges as discussed in this paper are; Poor Teachers’ Salary Structure and Other Remunerations,
Deteriorating condition of resources allocation for enhance Teaching-Learning process, Differential Categorization of Teachers,
Discriminative Political Interference and Low Degree of Autonomy is Accorded Teaching Profession and solutions were also
suggested. It was however concluded that teaching Profession should be accorded high respect through adequate motivation,
capacity buildings and ranked similarly with other Professions in Nigeria.
INFORMATION SERVICE AND ENTREPRENEURIAL SKILLS ACQUISITION FOR THE STUDENTS WITH SPECIAL NEEDS IN NIGERIAN SECONDARY SCHOOLS
(2017-08-22) Michael Olarewaju Ogundele; Chalibiya Simon
The paper examined information service and entrepreneurial skills acquisition for the
students with the special needs in Nigerian secondary schools. Since information provision for
the citizens is power, information services for developing entrepreneurial skills acquisition in
students with special needs, is inevitable. It is therefore essential for the educational mangers to
provide all the necessary information services which assist the students with special need. The
current expository study explained the concepts of information services, types of information,
flow of information, causes of information blockage, needs for entrepreneurship skills
acquisitions, methods of providing information services that will aid students with special needs
to acquire necessary entrepreneurial skills to help them in their later life. Suggestions were made
for the school managers to provide necessary information available for the career choices of
students with special needs especially students of secondary schools.
A Hybrid Backtracking and Pencil and Paper Sudoku Solver
(International Journal of Computer Applications, 2019-04) Onokpasa Eva; Bisandu Desmond; Bakwa Dunka
In an earlier research [1] it was found that based on the
number of iterations taken to solve puzzles from [2] the pencil
and paper (PnP) was the most efficient method for solving
Sudoku puzzles rated easy and medium by [2]. However for
more difficult puzzles this method p*roved ineffective. Next,
the method of alternating projections proved more efficient at
solving all test puzzles compared to the backtracking (BT)
algorithm. In this research work, a hybrid solver is created
using the pencil and paper method and backtracking methods.
This method solves all sample puzzles in finite seconds. The
execution time outperforms the BT method for most of the
sample puzzles.
