Occurrence of pesticides used in tobacco farming in edible vegetables and environmental samplesMunjanja, Basil K.; Madzivire-Penduka, Cecilia; Sanganyado, Edmond, 2013-09A method was developed and validated for the analysis of chlorothalonil (CT), dimethoate (DM) and triadimenol (TD) in soil, surface water and edible green vegetables. In method development, A range of solvents were evaluated, and ethyl acetate was ob[more...]
On a Fundamental Physical Basis forMaxwell-Heaviside GravitomagnetismNyambuya, G. G., 2014Gravitomagnetism is universally and formally recognised in contemporary physics as being the linear first order approximation of Einstein’s field equations emerging from the General Theory of Relativity (GTR). Herein, we argue, as has been done by ot[more...]
On a New 4-Vector Cosmological Field Theory.Nyambuya, G. G., 2005-05-05The original Dirac Equation is modified in the simplest imaginable and
most trivial manner to include a universal 4-Vector Cosmological Field term in the space and
time dimensions. This cosmological field leads to a modified Dirac Equation capable [more...]
On a simpler, much more general and truly marvellous proof of Fermat’s last theorem (I)Nyambuya, G. G., 2016-01English mathematics Professor, Sir Andrew John Wiles of the University of Cambridge finally and
conclusively proved in 1995 Fermat’s Last Theorem which had for 358 years notoriously resisted
all gallant and spirited efforts to prove it even by thre[more...]
On a Simpler, Much More General and Truly Marvellous Proof of Fermat’s Last Theorem (II)Nyambuya, G. G., 2014-09-24English mathematics Professor, Sir Andrew John Wiles of the University of Cambridge
finally and conclusively proved in 1995 Fermat’s Last Theorem which had for 358 years notoriously resisted all efforts to prove it. Sir Professor Andrew Wiles’s proo[more...]
On the Accelerated Expansion of the Universe and the Preponderance of Matter over Antimatter.Nyambuya, G. G., 2016-04The original Dirac equation is modified in the simplest imaginable and most trivial manner to
include a universal all-pervading and all-permeating Cosmic Four Vector Field (CFVF), μ. This
CFVF leads to a modified Dirac equation that violates all t[more...]
On the Cosmic Variation of the Fine Structure Constant. Was the Universe Created at an Instant?Nyambuya, G. G., 2015-02-28Without veering off the shores of conventional physics and without making any exogenous addition on our part, but well within the mathematical and physical logic of the accepted domains and confines of classical Maxwellian electrodynamics - in a very[more...]
On the expanding earth and shrinking moonNyambuya, G. G., 2014-03Exactly 101 years ago, German scientist Alfred Lothar Wegener, sailed against the prevailing wisdom
of his day when he posited that not only have the Earth’s continental plates receded from
each other over the course of the Earth’s history, but tha[more...]
On the Extra Anomalous Gyromagnetic Ratio of the Electron and Other General Spin-1/2 ParticlesNyambuya, G. G., 2015-04-15As is well known, amongst the greatest successes of the Dirac equation at its birth
where its ability to naturally account for spin as a relativistic phenomenon and its almost arcane prediction of the correct gyromagnetic ratio of the Electron. The [more...]
On the Fundamental Origins of the Dirac EquationNyambuya, G. G., 2016Despite its great success in explaining the physical world as we know it, the fundamental origins of the Dirac equation remains for the most part, enshrouded in deep mystery. What are the fundamental origins of this beautiful equation? To begin with,[more...]
On the Fundamental Theoretical Foundations of Newton’s Law of CoolingNyambuya, G. G., 2017-04Unlike the famous Stefan-Boltzmann Law (SBL),
one can safely say that Newton (1700)’s Law of Cooling
(NCL) is without any fundamental theoretical foundations
and that – no importance has been placed to seek the most
fundamental basis of this law.[more...]
On the gravitational bending of light —Was Sir Arthur Stanley Eddington right?Nyambuya, G. G.; Simango, W., 2014-03The paramount British-Led (May 29, 1919) Solar Eclipse Result of Eddington et al. has been tremendous if not an arcane effect in persuading scientists, philosophers and the general public, to
accept Einstein’s esoteric General Theory of Relativity ([more...]
On the Perihelion Precession of Solar Planetary OrbitsNyambuya, G. G., 2013-02The present letter presents an improved version of the Azimuthally Symmetric
Theory of Gravitation (ASTG-model) which was presented for the first time in the
present journal four years ago. We propose a solution to the standing problem of
the -pa[more...]
On the Plausibility of an Upper Bound Uncertainty PrincipleNyambuya, G. G., 2014-10We argued previously from a physical and number theoretic standpoint that an upper bound speed
limit such as the speed of light implies the existence of a lower limit to the duration of events in the
Universe. Consequently, this leads to a minimum [more...]
On the Preponderance of Matter over AntimatterNyambuya, G. G., 2015Quantum electrodynamics (QED) is built on the original Dirac equation, an equation that exhibits
perfect symmetry in that it is symmetric under charge conjugation (C), space (P) and time (T) re-
versal and any combination of these discrete symmetri[more...]
On the Radiation Problem of High Mass Stars.Nyambuya, G. G., 2010-03-10A massive star is defined to be one with a mass greater than 8 - 10M .
Central to the on-going debate on how these objects [massive stars] come into being is
the so-called Radiation Problem. For nearly forty years now, it has been argued that the[more...]
