    This article is published on IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS). It is a study conducted on cattle based in Zimbabwe Matabeleland South Province. It focuses on psramphistome effects on aspects of blood plasma composition in infected cattle.Cattle originating from various localities in Matabeleland South Province were examined for adult Paramphistome prevalence. Of the three thousand 27% were infected with paramphistomes. For identification of paramphistomes, the structures and measurements of diagnostic features were made in median sagittal sections. Analysis of the structures of the acetabulum, pharynx and genital atrium revealed the following parasites in the area: Calicophoron microbothrium, Calicophoron clavula, Calicophoron calicophorum, Calicophoron raja, and Gigantocotyle symmeri in 20 %, 2 %, 5%, 2 % and 2% of cattle examined respectively. The visible damage by adult parasites on the hosts? tissue were as a result of their sucking the reticulum and rumen mucosa into the acetabulum, which eventually nipped off, leading to slightly hardened areas devoid of rugae due to necrosis. In a few severe cases the papillae was damaged and catarrhal pus like exudate was noticed on the mucosa. Fifty coded Nguni cattle aged three years, infected with paramphistomes had their final carcass mass and blood chemistry recorded. Only total protein and cholesterol showed significant difference between the infected and the controls p<0.05. The final carcass mass was significantly different between cattle harboring more than 500 parasites per animal and the controls P<0.05.Funded by NUST Research Board, Mpilo Hospital Laboratory for blood analysis, and the SABRIO PROJEC

    On the Plausibility of an Upper Bound Uncertainty Principle

    No full text
    This article is published in Prespacetime Journal which has been published by Quantum Dream, Inc. in October 2014.We 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 characteristic length separation for events in the Universe. Herein, we argue that matter and energy that is in compliance with and in observance of the upper bound light speed limit is governed by the lower limiting uncertainty principle of Heisenberg. We also ask the natural and logical question `What would an upper bound uncertainty principle mean?' We come to the interesting conclusion that an upper bound uncertainty principle must apply to particles that travel at speeds greater than the speed of light. Further, we argue that consequently a tachyon must exist in a permanent state of con nement and must be intrinsically and inherently unstable in which event it oscillates between di erent states. These two requirements place quarks in a position to be good candidates for tachyon

    On a Fundamental Physical Basis forMaxwell-Heaviside Gravitomagnetism

    No full text
    This is a journal articleGravitomagnetism 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 others in the past by others that, gravitomagnetism can be viewed as a fully-fledged independent theory of gravitomagnetism that can be divorced from Professor Einstein?s GTR. The gravitomagnetic theory whose exposition we give herein is exactly that envisioned by Professor Maxwell and Dr. Heaviside. The once speculativeMaxwell-Heaviside Gravitomagnetic theory now finds full justification as a fully fledged theory from Professor Jos?e Hera?s Existence Theorem which states that all there is needed for there to exist the four Maxwell-type field equations is that a mass-current conservation law be obeyed. Our contribution in the present work ? if any; is that we demonstrate conclusively that like electromagnetism, the gravitomagnetic phenomenon leads to the prediction of gravitomagnetic waves that travel at the speed of light. Further, we argue that for the gravitational phenomenon, apart from the Newtonian gravitational potential, there are four more potentials and this operate concurrently with the Newtonian potential. At the end of it all, it is seen that the present work sets the stage for a very interesting investigation of several gravitational anomalies such as the ponderous Pioneer Anomaly, the vexing Flyby Anomalies, the mysterious Anomalous Rotation Curves of Spiral Galaxies and as-well, the possibility of the generation of stellar magnetic fields by rotating gravitationalmasses

    Revisiting the 1887 Michelson-Morley Experiment (Paper IV)

    Journal article from Scientific Research. 2014. Journal of Morden Physics. Vol. 5(12).This is the last instalment in a four part series, the aim of the work being to introduce absolute motion into Einstein?s Special Theory of Relativity (STR). In Paper (I), we provided a new solution to the traditional twin paradox of Einstein & Langevin. This new solution suggests that hidden within the labyrinth of its seemingly coherent and consistent structure and fabric, Einstein?s STR implies absolute motion. In Paper (II) we proposed the truly paradoxical case of the symmetric travelling twins. It is seen therein that this case unearths the deeply hidden inconsistency of Einstein?s STR. This irretrievable contradiction seen in the case of the symmetric twins not only suggests, but points to the undeniable need and necessity for absolute motion. We thus set-forth in Paper (III) a relativistic aether model, which at best can be described as the Special Theory of Relativity in Absolute Space (STRAS). Having build the theory, we herein revisit several experiments carried out to detect absolute motion. The new theory i.e. the STRAS, requires that these experiments be recalibrated. So doing ? i.e. recalibrating these experiments, we find that the Earth?s speed through the hypothetical aether medium varies in the range ? 130 ? 350 kms?1 i.e. 240 ? 110 kms?1

    A journal article from Journal of Morden Physics, 2014, 5(12).This is the third instalment in a four part series, the aim of the work being to introduce absolute motion into Einstein?s Special Theory of Relativity (STR). In Paper (I), we provided a new novel and ingenious solution to the traditional twin paradox of Einstein. This new solution suggested that hidden within the labyrinth of its seemingly coherent and consistent structure and fabric - against the deeply entrenched philosophy of relativity due to Einstein; Einstein?s STR implies absolute motion. In Paper (II) we proposed the truly paradoxical case of the symmetric travelling twins. It is seen therein that this case unearths the hidden inconsistency deeply embedded in Einstein?s STR. This irretrievable contradiction seen in the case of the symmetric twins not only suggests, but points to the undeniable need and necessity for absolute motion. Taking this implied absolute motion into account ? herein, we thus set-forth a relativistic aether model, which at best can be described as the Special Theory of Relativity in Absolute Space (STRAS)

    On the gravitational bending of light ?Was Sir Arthur Stanley Eddington right?

    This work is licensed under the Creative Commons Attribution International License (CC BY)The 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 (GTR) thereby ?deserting? Newtonian gravitation altogether, especially in physical domains of extreme gravitation where Einstein?s GTR is thought or believed to reign supreme. The all-crucial factor ?2? predicted by Einstein?s GTR has been ?verified? by subsequent measurements, more so by the most impressive and precision modern technology of VLBA measurements using cosmological radio waves to within 99.998% accuracy. From within the most well accepted provinces, confines and domains of Newtonian gravitational theory, herein, we demonstrate that the gravitational to inertial mass ratio of photons in Newtonian gravitational theory where the identities of the inertial and gravitational mass are preserved, the resulting theory is very much compatible with all measurements made of the gravitational bending of light. Actually, this approach posits that these measurements of the gravitational bending of light not only confirm the gravitational bending of electromagnetic waves, but that, on a much more subtler level; rather clandestinely, these measurements are in actual fact a measurement of the gravitational to inertial mass ratio of photons. The significant 19% scatter is seen in the measurements where white-starlight is used, according to the present thesis, this scatter is seen to imply that the gravitational to inertial ratio of photons may very well be variable quantity such that for radio waves, this quantity must?to within 99.998% accuracy, be unity. We strongly believe that the findings of the present reading demonstrate or hint to a much deeper reality that the gravitational and inertial mass, may?after all; not be equal as we have come to strongly believe.National University of Science & Technology (NUST)?s Research & Innovation Department and Research Boar

    Development of a Braided Polypropylene Rope Using Polypropylene Tape Yarns

    Development of a Braided Polypropylene Rope Using Polypropylene Tape Yarns is a journal article.Traditionally, braided ropes are manufactured using either staple yarns or multifilament yarns. This study therefore sought to break this traditional paradigm by uniquely and economically manufacturing braided polypropylene ropes using polypropylene tape yarns. A recipe made up of virgin polypropylene granules, calcium carbonate and black masterbatch was used to produce a polypropylene plastic sheet, which was extruded on a Barmag machine. Tape yarns with a width of 22 mm on average were produced. Count, width, thickness, elongation and tensile strength of the tape yarns used to produce the rope were tested. The elongation and tensile strength tests were done on a Micro 500 Testometric strength-testing machine. Test results on the tape yarns revealed that they have properties that fall within the standard range of fibrillated polypropylene tape yarns. Sorptive properties of both the tape yarns used and the braided rope developed revealed a slight increase in water absorbance to approximately 0.15% compared to standard water absorbance of less than 0.1%. This increment in water absorbance, however, did not change the floating properties of both the tape yarns and the braided rope as they both remained with their positive buoyancy. Also, no signs of microbial attack were seen on the tape yarns and the braided rope by naked eyes after exposing the samples to water. The resultant braided rope produced was made up of 12 X 4973 denier polypropylene tape yarns with a 9200-denier polypropylene bailer twine as the core. The count and diameter of the resultant rope were found to be close to those of hazard barrier and hydro-pulling ropes and were also analogous to those of 5 mm cotton braided ropes produced

    Digital Access and E-Government: Perspectives from Developing and Emerging Countries

    No full text
    This book chapter is published in the IGI Global book series Advances in Electronic Government, Digital Divide, and Regional DevelopmentThe concept of e-Government sub-assumes that of digital access to activities of public and private sector organisations. Explicitly, digital access includes improving government processes, connecting citizens, and building external interactions. Following the formation of the inclusive government as determined by the Global Political Agreement (GPA), Zimbabwe established the Ministry of Information Communication Technology whose mission is to promote the deployment and use of Information and Communication Technologies (ICTs) to intensify national competitiveness and growth. Driving the digital access and e-Government agenda in Zimbabwe is a Modernisation Unit within the Office of the President and Cabinet and the Ministry of Information Communication Technology guided by ?Zimconnect,? the e-Government framework, and other enabling instruments. Particular attention is paid to instruments that enable digital access and e-Government in Zimbabwe. The chapter attempts to contextualise digital access and e-Government, outlines e-Government policy objectives and constraints, explains the e-Government framework, including ?Zimconnect? and others, and concludes with a section on strategies for enabling digital access and e-Government with a special focus on the possible role of library and information services

    A Perdurable Defence to Weyl?s Unified Theory

    No full text
    A Perdurable Defence to Weyl?s Unified Theory is a published article of the Applied Physics department.Einstein dealt a lethal blow to Weyl?s unified theory by arguing that Weyl?s theory was at the very best ? beautiful, and at the very least, un-physical, because its concept of variation of the length of a vector from one point of space to the other meant that certain absolute quantities, such as the ?fixed? spacing of atomic spectral lines and the Compton wavelength of an Electron for example, would change arbitrarily as they would have to depend on their prehistories. This venomous criticism of Einstein to Weyl?s theory remains much alive today as it was on the first day Einstein pronounced it. We demonstrate herein that one can overcome Einstein?s criticism by recasting Weyl?s theory into a new Weyl-kind of theory were the length of vectors are preserved as is the case in Riemann geometry. In this New Weyl Theory, the Weyl gauge transformation of the Riemann metric g and the Maxwellian electromagnetic field A are preserved

    Secular increase in the earth?s LOD strongly implies that the earth might be expanding radially on a global scale

    This work is licensed under the Creative Commons Attribution International License (CC BY).Exactly 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 that they are currently in a state of motion relative to one another. To explain this, Wegener set forth the hypothesis that the Earth must be expanding as a whole. Wegener?s inability to provide an adequate explanation of the forces and energy source responsible for continental drift and the prevailing belief that the Earth was a rigid solid body resulted in the acrimonious dismissal of his theories. Today, that the continents are receding from each other is no longer a point of debate but a sacrosanct pillar of modern geology and geophysics. What is debatable is the energy source driving this phenomenon. An expanding Earth hypothesis is currently an idea that is not accepted on a general consensus level. Antiproponent of the expanding Earth mercilessly dismiss it as a pseudo or fringe science with their main point of rejection being the energy source to power this supposed expansion. Be that as it may, we show herein that from the well accepted law of conversation of spin angular momentum, Stephenson [1]?s result that over the last 2700 years or so, the length of the Earth?s day has undergone a change of about +17.00 ?s/yr, this result invariably leads to the plausibility the Earth may very be expanding radially at a paltry rate of about +0.60 mm/yr. If correct, this simple fact, automatically move the expanding Earth hypothesis from the realm of pseudo or fringe science, to that of plausible science. Keyword
