The study examines the relationship between bank
credit and economic growth in Nigeria by considering the total bank credit
extended to the production sector (which comprises manufacturing, agriculture,
fishery and forestry, mining and quarrying, real estate and construction), general
commerce sector (comprising: bills discounted, domestic trade, exports and imports)
and services sector (comprising: public utilities, transport and communication,
credit to financial institutions). Time series dat...

In this paper, the Magnetohydrodynamic (MHD) Flow of
Viscous Fluid over a Nonlinear Stretching Sheet is investigated numerically.
The partial differential equations governing the flow are reduced to a non
linear ordinary differential equations by using similarity transformations. The
resulting
transformed equations are numerically solved by an explicit finite difference
scheme known as the Keller Box Method. The velocity profiles are determined
and the effects of the magnetic parameter and non l...

This study analyzes a single server queueing
model with a time-dependent arrival rate and
service rate is constant. In this model, the incoming arrivals are Poisson
stream; service time is exponentially distributed and the first-come first-served
queueing discipline. We obtain an explicit expression for the state
probability distribution with time-dependent arrival rate using unit step
function.

Policy reforms in education have considerable
potential to correct social inequities and assist in the building of more
inclusive societies either through improved efficiencies and/or equity in education
service provision. Primary education is a public service whose consumption has
huge positive externalities—social and economic benefits. In many developing
countries, girls are usually excluded from
the consumption of this service for a variety of reasons—some of which are
social, cultural or ec...

Calcifying Epithelial Odontogenic Tumor (CEOT) is a
rare benign odontogenic tumor that was first described by Pindborg in 1955. It
accounts for less than 1% of all odontogenic neoplasms. This lesion is a locally
aggressive benign odontogenic neoplasm arising from epithelial tissue. The radiographic
appearance is characterized by uni- or multilocular radiolucent areas with
radiopaque masses of varying sizes; there is a frequent association with an
unerupted tooth. Most CEOT are intraosseous lesio...

Background: The pregnancy outcome following cervical
cerclage for women with cervical incompetence is generally favourable. However,
the outcome for emergency cerclage is less favourable. Methodology: A
retrospective analysis of the case notes of pregnant women who underwent
emergency cervical cerclage from January 2007 until December 2010 at Garkuwa
Hospital and Sheehan Hospital was performed. Results: There were a total of 56
cases of cervical cerclage comprising 46 elective and 10 emergency c...

In this paper new
method is introduced for complex numbers; this method does not include imaginary
number “i” but produces the same
results that occur in Addition, Subtraction, Multiplication & Division of
complex numbers, also proof of Eluer Formula eiθ and De Moivre theorem without using imaginary number
“i”. Furthermore placing the light on
the square root of a negative number, the square root of a negative number is
equal t ...

The various methods of remediation of contaminated
soils include isolation, immobilization, toxicity reduction, physical
separation and extraction. In this context, a noteworthy technique is vermicomposting,
which uses worms to break down recent organic matter, turning it into a chemically
more stable form able to retain metal ions, rendering them unavailable to the
environment. To understand the transport of these elements in the soil, it is
necessary to study their dynamics in the environment....

In the present theoretical work, an attempt has been
made to derive an expression for the quantum volume of discrete space and its
growth rate using first rank tensorial Einstein-Gauss gravitation law, Einstein’s
mass energy equivalence and Heisenberg’s uncertainty principle. It is found
that the universe may have come into quantum existence with volume thrice the
Planck’s volume within the framework of physical laws when it already had an
age ~10 ﹣43 s provided the Planck’s time is at...

The author discusses the conceptual bases related to
general and clinimetric properties of stroke scales, relating them to its
application in research and clinical practice. This paper briefly presents the
definitions of reliability and validity and its usage in clinical studies, and didactically
demonstrates statistical approaches for obtaining agreement and correlation coefficients.
Finally, it proposed to criticize the most common bias in the literature on the
use of these concepts and forwar...
