The cytobacteriological
examination of urine is a biological test most commonly asked in the hospital.
The results of a large part of urinary sample analyzed are negative,
representing a heavy workload for bacteriology laboratories, burden that we
would like to limit. In this context the aim of our study was to evaluate a
screening test for urinary tract infection by urine dipstick compared to the
reference method; th ...

Insert Glycolysis that occurs in vitro venous blood samples is known to induce a rapid drop in blood sugar. The use of an antiglycolytic is prob-lematic, sodium fluoride creates hemolysis and mono-iodoacetate is active two hours after sampling. However, many laboratories are uncentrifuged specimens from distant sampling sites with varying delivery times some-times several hours. The objective of this study is firstly to determine ...

As a follow up of the
author’s earlier papers the new theory of radiation reaction is placed on a
sound theoretical basis. This includes the nature of the equation of motion
both under a relativistic Lorentz transformation as well as under a
non-relativistic Galilean transformation. It is claimed that both momentum and
energy carried out by the radiated fields need to be considered to reach the
desired results. It is also sho ...

This paper discusses the Bayesian
approach to estimation and prediction of the reliability of software systems
during the testing process. A Non-Homogeneous
Poisson Process (NHPP) arising from the Musa-Okumoto (1984)
software reliability model is proposed for the software failures. The
Musa-Okumoto NHPP reliability model consists of two components—the execution
time component and the calendar time component, and is a popular model ...

This study demonstrates the effectiveness of Klopfer’s taxonomy and a candidate
hypothetico-deductive thinking and reasoning theory of didactic transposition,
in teaching critical thinking skills, analogies and transferability of
knowledge for problem-solving now and for the future in the experimental sciences.
It was conducted in four socio-cultural zones of Cameroon involving 307 high school students (166 English-speaking and

In this paper, we have investigated and introduced some new definitions of transitivity on the set of all continuous maps, denoted by , called the point-wise convergence transitive, the compact-open transitive and point wise convergence topological transitive sets. Relationship between these new defini-tions is studied. Finally, we have introduced a number of very important topo-logical concepts and shown that every compact-open ...

represents a major public health burden with more than 375 million people with
chronic hepatitis B infection and 130 to 150 million with hepatitis C for 2016.
Sub-Saharan Africa has the heaviest burden of the epidemic. Objective: The objective of this review is to present
the characteristics of hepatitis B and C infections (HBV and HCV), present the
synthesis and estimate its magnitude in the Democratic ...
