The overall objective of this paper is to demonstrate the relevance of
deduction (with/out falsification) to qualitative research. It provides the
reader with a concise synopsis of an alternative approach to qualitative
research enquiry. The philosophy is supported by Hyde [1] who believes that both qualitative and quantitative research possess
deductive and inductive components. It supports this by proposing that a
quasi-deductive approach based on fo...

For a w-hyponormal operator T acting on a separable complex Hilbert
space H, we prove that: 1) the quasi-nilpotent part Ho(T - λI ) is equal to...

The purified Immunoglobulin G (IgG) is effectively used in passive
immunization. There are various methods to isolate the IgG from serum, with its
own advantages and disadvantages. In the current study, a comparative efficacy
of the affinity chromatography using Protein A—Sepharose and ion
exchange chromatography using DEAE Sephadex A50 was done with regard to yield
and purity of IgG. Both methods were found equally effective in isolation of
pure IgG with similar recovery, indicating that resear...

Twelve durum wheat genotypes were evaluated for their grain yield and
related traits using two rates of nitrogen fertilizer application
(69 kg N ha ﹣1 and 115 kg N ha ﹣1) in a randomized complete block design with three replications. The
experiment was done on Vertisol at Adet Agricultural Research Center in the
main cropping season 2009. All agronomic traits respond positively to applied
nitrogen rates. The highest grain yield (33.8 Qt·ha ﹣...

In this paper, we obtain some results on compact
operators. More specially, we prove that if T is a unitary operator on a
Hilbert space H, then it is compact if and only if H has a finite
dimension. Also, we prove that, if H is a Hilbert space with Heine-Borel
property, then  .

A new numerical evaluation of the Newtonian component of Mercury’s
perihelion advance over more than two centuries starting from about the year
2000 is made. Results are given for about the last 30 years of this interval.
Comparison with perturbation theory calculation results indicates necessity of
revision of previously held estimates of this quantity.

Variations in level of fluid in wells caused by
Earth tides and earthquakes are governed by two leading processes: deformation
of medium and filtration. These processes are described by identical systems of
equations and are united by the term “hydrodynamical phenomena”. The exact
solution is obtained for the problem of level variations in wells due to Earth
tides. The similar problem is solved for short-term precursors of a tectonic
earthquake. Results are consistent with data of field observat...

This study examined the influence of spatial
comfort and environmental workplace ergonomics on the job satisfaction of
librarians in the federal and state university libraries in Southern Nigeria.
The study adopted the survey research
design. The total enumeration technique was used to survey the 500
librarians from the 37 federal and
state universities libraries in Southern Nigeria. Descriptive statistics was
used to analyze the data collected. The findings revealed that there was
a positive re...

Let  be a sequence
of completely asymmetric stable process or stable subordinators defined on a
common probability space . In this paper, for proper selection of norming
constants, we study almost sure limit inferior for increments of stable
subordinators of geometr...

In this paper, the model of a multiverse made up of entangled pairs of
universes is presented. The arrow of time obtained from the principles of
thermodynamics and the arrow of time given by the thermodynamics of entanglement
for single universes are analyzed. The latter requires that the single
universes expand once they have crossed the quantum barrier at the Euclidean
regime. The possible relationship with respect to the growth of local
structures in a single universe is also discussed.
