DESIGN AND CONSTRUCTION OF A LOW-COST HEARING AID
(International Journal of Scientific & Engineering Research, 2019-09) Domtau, D.L.1, Chagok, N.M.D.2, Akparanta, P.H.3, Fom, T.P.4, Mado, S.D.5
A low-cost hearing aid device was designed and constructed to produce an amplified sound for people with hearing loss. A 9V dc was used as the
power supply. The condenser microphone was used as input transducer to pick up sound from the environment for conversion to electrical signal,
NPN transistor (BC548C) along with three capacitors and five resistors were used as pre-amplifier.to amplify. The integrated circuit (IC)
TDA2822M, available in 8-pin mini chip package and specially designed for portable power amplification was used for the amplification
function. A 32 ohms ear phone was used as the output transducer to convert the amplified electrical signals back to sound. The computed current
gain was 100. Rc was obtained as 3.3Ω, 𝐼𝐵 = 0.025𝐴, 𝐼𝐸 = 2.5𝐴, 𝑅𝐸 = 1.5Ω, the impendence 𝑍0 = 1.9Ω.

RESOURCE UTILIZATION AND QUALITY DELIVERY OF NOMADIC EDUCATION PROGRAMME IN NORTH CENTRAL NIGERIA FOR GLOBAL COMPETITIVENESS
(The Online Journal of New Horizons in Education, 2019-07) OGUNDELE, MICHAEL OLAREWAJU (Ph.D)
The study examined the relationship between resource utilization and quality delivery of nomadic education
programme in plateau state Nigeria for global competitiveness. A correlational research design was adopted for
the study. The population for the study are 650 respondents which comprised of the headteachers, teachers,
parent-teachers, association executives and prefects. Sample of 450 respondents were selected using
proportionate stratified random sampling technique. Three research questions and three hypotheses were
formulated for the study. A self-designed research instrument tagged resource utilization and quality delivery
questionnaire (RUQUDQ) was validated by the experts in Economic Education, Educational Management and
the reliability index of 0.82 was obtained after subjecting the instruments to split half reliability method and
tested at .05 using spearman ranking order statistics. Descriptive statistics like percentages, mean score and
standard deviation was used to answer all the research questions whole. The hypotheses were tested with
Pearson product moment correlation statistics at 0.05 significance level. It was however concluded that all the
hypotheses tested were rejected which showed that low significant relationship existed between resource
utilization and quality delivery indicators in nomadic education in Plateau state which affect global
competitiveness of the programme in the state. It is however recommended that the local resources in nomadic
education should be used during teaching-learning processes using practical and activity oriented for effective
utilization of the available resource s. however, innovative approach for resource utilization in nomadic
education in plateau state will definitely enhance global competitive of the programme.
Architecture Design Pratice in Nigeria: What Role for a Design Guide
(Humanities and Social Sciences Review, 2014) .Allu,Evelyn L. A
The shift from traditional design practices to sustainable design practices, the challenges of climate
change and the global concern for the sustainability of the built environment motivate this study. The
focus for this paper is to encourage sustainable conscious design by architects in Nigeria, through the
use of a design guide. The survey was carried outto provide insights into the design practices and the
perceptions of these professionals in regards to their roles to provide sustainable buildings and their
willingness to use design guide in order to improve their design output. Findings suggest that on one
hand, there is a low level (41%) of knowledge on the relationship between climate change and
buildings. On the other hand, there is the willingness (100%) on the part of these professionals to use a
sustainable design guide. This study also recommends a design checklist for architects, clients and
design approval agency in Nigeria in order to ensure standards and compliance to the use of sustainable
features by designers
PREVALENCE OF GASTROINTESTINAL PARASITIC INFECTION IN A SECONDARY HEALTH FACILITY IN DADIN KOWA COMMUNITY, JOS METROPOLIS, CENTRAL NIGERIA
(INTERNATIONAL JOURNAL OF CURRENT RESEARCH, 2012-06) Emmanuel I. Bigwan; Gabriel C. Okezie; Sheyin, Z.
Objectives: This study investigated the prevalence of gastro- intestinal parasites among patients
attending a secondary health care facility in Dadin Kowa community, Jos metropolis, North Central
Nigeria.
Methods: Fecal samples from 300 patients were examined microscopically using formal ether
concentration technique.
Results: Out of 300 stool samples examined the overall prevalence of intestinal parasites was
43(14.3%).The males had the highest with 16(16.5%) while the females had 27(13.3%).Patients in
age group 21-40 years had the highest with 26(16.6%) while age group 1-20 years had the lowest
with 10(11.0%).The study revealed that those patients that uses water closet system had the lowest
prevalence of 3(3.0%), followed by those using pit latrines with 18(16.4%), while those that usually
defecate indiscriminately in the bush/open air had the highest with 22 (24.4%). The study reveals that
those with non-formal education had the highest with 18(22.5%), followed by those with primary
education with 13(21.7%), those with secondary education had 7(10.0%), and those with tertiary
education had the least with 5(5.6%).The study indicates that those using ponds/stream water as
sources of drinking /domestic purposes had the highest with 6(60%),followed by those using well
water with 34(37.8%) and the least were among those using tap/bottled water with 3(1.5%) .The
gastrointestinal parasites recovered in the study area were Entamoeba histolytica, Ascaris
lumbricoides, Hookworm and Schistosoma mansoni having a prevalence of 8.7%, 3.7%, 1.3% and
0.7% respectively.
Conclusion: The high prevalence recorded was found to be associated with poverty, illiteracy, poor
water supply and poor environmental sanitation.
A Class of New Block Generalized Adams Implicit Runge-Kutta Collocation Methods
(International Journal of Scientific & Engineering Research,, 2015-12-12) 1Kumleng, G.M.,; 2Chollom, J. P; 3Omagwu ,.S.
In this paper, the reformulation of the block generalized Adams methods into block generalized Adams implicit Rung-Kutta methods for step numbers k =3, 4, 5, is considered. This is because of the usefulness of block implicit Runge-Kutta methods for the solution of stiff ordinary differential equations. The new methods proposed in this paper turn out to be A-stable and possess the stability properties of the Runge-Kutta methods and have implicit structure for accurate and efficient implementation. Numerical examples obtained demonstrate the accuracy and efficiency of the new block methods.
