E. Hamza <p>The study of magnetic suspensions (MS) and magnetic field effects on their rheological properties is of evident practical importance due to its ability to orient and change their physical properties, especially their viscosity, by magnetic fields. This research presents the effect of a uniform magnetic field on the flow of MS in the annular region between two concentric cylinders. The motion of the fluid is due to the rotation of the inner cylinder with a constant angular velocity. An exact solution of the governing equations is obtained in the form of modified Bessel functions of the first and second kinds. The torque, which must be applied to the inner cylinder in order to maintain the rotation, is also calculated. The results show that as the magnetic parameter increases, the velocity profile decreases, while the torque increases due to the effect of magnetic force against the flow direction.</p> <p>In order to model the magnetoviscous effects, experiments were performed for different shear rates and different magnetic field strengths by using specially designed rheometers. The studied samples are iron oxide-water-glycerol system, &nbsp;ferrofluid nanoparticles, MAG DX biocompatible ferrofluid. The theoretical analysis is based on Giesekus model for MS. This model gives more accurate results and takes into account the effects of viscoelastic shear thinning characteristics. It is found that a magnetic field increases the viscosity of all suspensions under consideration. Finally, new proposed correlation for the viscosity of MS as a function of both shear rate and magnetic field has been suggested.</p> 2019-05-06T00:00:00+00:00 Copyright (c) 2019 S.E. E.

E. Hamza <p>This Paper deals wit the effects of suction (injection) on magnetohydrodynamic (MHD) steady flow of a viscous and electrically conducting fluid in an annular porous region between two concentric cylinders. The inner cylinder is rotating with uniform angular velocity and the outer one is fixed. The two cylinders are&nbsp; porous with uniform permeability. It is assumed that the suction rate at the inner cylinder is equal to the injection rate at the outer cylinder. A uniform axial magnetic field was applied perpendicular to the flow direction. The flow resistance presented by the porous medium is governed by the Darcy law. By using similarity transformation, the governing partial differential equations have been transformed to a system of nonlinear ordinary differential equations. The solution of the obtained system in its general form has been obtained. Analytical expression for velocity field is obtained in terms of Bessel function of first and second kind. The effects of various parameters such as susction (injection), magnetic and permeability parameters on the flow are discussed and the obtained results are presented graphically. The obtained figures show that, the velocity distribution increased with the increase of permeability parameter of the the porous medium and with suction process. On the other hand, the velocity distribution decreased with the increase of magnetic parameter and with injection parameter.</p> 2019-05-20T05:59:15+00:00 Copyright (c) 2019 S.E. E.

The microstructure characteristics of the tested alloys had been investigated using optical microscope (OM), scanning electron microscope (SEM) and x-ray diffraction (XRD). The impression creep had been carried out using Vickers micro-hardness indenter under different loads (10, 50 and 100gm). The stress exponent values were found to be varied from 3.2 to 8.4. The energy activating the creep processes support dislocation climb as the rate controlling mechanism. The dislocation mobility was restricted due to the agglomerations of the Ag3Sn eutectic phase in the above three solders. Whereas; the presence of the twinning of ?-Sn phase, and the dispersion of fine CdSn1.9 IMCs throughout Sn-3.5wt.%Ag-0.27wt.%Cd made strongly blockage of the dislocation motion.</p> 2019-05-20T06:42:42+00:00 Copyright (c) 2019 Amal Mohamed Yassin, B.A. Khalifa, R.

The resultant fibers were characterized using X-ray differaction (XRD), scanning electron microscope with energy dispersive X-Ray spectrophotometry (SEM,EDX), Fourier transform infrared (FTIR). SEM,EDX and FTIR exhibited a total decomposition of the organic precursor after calcination and formation of zinc oxide (ZONF and CZONF). The mean fiber diameter was found to be increased with increasing MWCNTs concentration and ranged 490-767 nm. XRD patterns indicated that ZnO was corundum with the hexagonal wurtzite structure. The crystallite size of ZONF and CZONF were determined by shurrer equation to be26 and&nbsp; 29.7&nbsp; nm, respectively. The optical analysis indicated that the percentage transmittance increased after calcination.The band gap for the electrospun fibers before and after calcination was calculated. CZONF nanofibers have elec­trical properties similar to those of semiconductors.

Basically you take a 4-dimensional manifold, transform them into two superimposed Riemann Spheres and isolate a circle (call this Pp) in one of the spheres. Then one specifies the circle to turn by a unit amount (the turn is an quantum rotation: turn from state A to state B without visiting the in between states) as measured along the circle, every time the Pp encounters a space point. Space fluctuates and expands so this does not give a static circle Pp. The circle's infinity point stays at the north pole of the Riemann Sphere for any finite rotation since: infinity - constant = infinity. Using this one can define basic spacetime and from basic spacetime, Time can be defined if we require special particles to be in the particles of a clock. We go on to define photons and antiphotons. The model predicts that there is a direction in which photons (from the same process) are never emitted. We continue to define a pi-minus.</p> 2019-08-14T08:26:42+00:00 Copyright (c) 2019 Willem Francois Esterhuyse Fine-structure constant from Sommerfeld to Feynman 2019-08-30T04:12:14+00:00 Michael A. Sherbon <p>The fine-structure constant, which determines the strength of the electromagnetic interaction, is briefly reviewed beginning with its introduction by Arnold Sommerfeld and also includes the interest of Wolfgang Pauli, Paul Dirac, Richard Feynman and others. Sommerfeld was very much a Pythagorean and sometimes compared to Johannes Kepler. The archetypal Pythagorean triangle has long been known as a hiding place for the golden ratio. More recently, the quartic polynomial has also been found as a hiding place for the golden ratio. The Kepler triangle, with its golden ratio proportions, is also a Pythagorean triangle. Combining classical harmonic proportions derived from Kepler’s triangle with quartic equations determine an approximate value for the fine-structure constant that is the same as that found in our previous work with the golden ratio geometry of the hydrogen atom. These results make further progress toward an understanding of the golden ratio as the basis for the fine-structure constant.</p> 2019-08-30T04:09:59+00:00 Copyright (c) 2019 Michael A. Sherbon A Trial to Predict the Diurnal Global Solar Irradiance Received On A Horizontal Plane for Clear Days in Terms of The Solar Angles. 2019-09-13T11:29:40+00:00 Samia Sayed Shaban <p>A general distribution function is suggested to predict both symmetrical and asymmetric diurnal global solar irradiance q (t) W/m<sup>2</sup> received on a horizontal surface, where “t” is the local day time "h" .The distribution is given in terms of well-established parameters, namely: t<sub>d</sub> :- the length of the solar day expressed in term of the solar angles.</p> <p>t<sub>max</sub> :- the time of the day at which the irradiance reaches its maximum value q<sub>max</sub> W/m<sup>2</sup> for symmetrical distribution&nbsp; t<sub>max</sub> = &nbsp; i.e. &nbsp;it occurs at the midday time.</p> <p>t<sub>d</sub> , t<sub>max</sub> and q<sub>max</sub> are taken as parameters.</p> <p>The suggested expression can be easily integrated along the length of the day time. This gives the daily totals of the received solar energy per unit horizontal area.This is of vital technical importance for solar energy exploitations and applications. &nbsp;Comparison between computed according to the present model and published experimental meteorological data in Barcelona (Spain), Hong Kong (China), Jeddah and Makah (Saudi Arabia) is given as illustrative examples. Comparison with the published trials for the same locations is also clarified. The introduced model itself gives good fitting for the intermediate interval points of the local day time which is the more effective region.</p> 2019-09-13T11:28:48+00:00 Copyright (c) 2019 Samia Sayed Shaban The Inverse Infinite Spiral Placement of Prime Numbers and Their Derivatives at the Cone of Pythagoras 1:3 2019-09-27T05:48:16+00:00 Vinoo Cameron <p>All mathematics of placement in this paper is mathematically absolute and precise by clear mathematics. This paper(<strong>section1</strong>) is the very basic “synopsis” of an upcoming book by the author “The God of Papa Einstein and Sir Isaac Newton “. It delineates the predictable expanding spirals of the prime numbers and their derivatives, by two cords, that hug the half-line of the 1:3 Pythagoras inverse cone. The <em>inner spiral</em> of all predictable spirals of prime numbers and their derivatives and the <em>outer spiral</em> at the predictable template of a spiral of prime number 5(+10,+20 alternate), which is the exact replicate of the <em>inner spiral</em> of prime numbers and their derivatives. The two spirals expand at two separate predictable geometric intervals, the <em>outer spiral</em> expanding predictably slower than the inner spiral as a replicate in geometric placement and in a sieve . These prime numbers and their derivatives ( Pseudo prime numbers) are sieved by placement in the continuum&nbsp; by a&nbsp; predictable formula demonstrated by the table at the end of this paper.</p> <p>In a separate exhaustive (<strong>Section 11) </strong>of this paper to be submitted separately, the author along with a contributing physicist discusses the synopsis of the &nbsp;patent configuration of prime numbers at the 1:3 cone, that is the &nbsp;genesis of the curvature of space and format -1 zero by the placement of prime numbers and their derivatives .”The mother of all science is mathematics”, this paper celebrates that dictum.</p> 2019-09-25T11:06:15+00:00 Copyright (c) 2019 Vinoo Cameron Golden Ratio Geometry and the Fine-Structure Constant 2019-10-22T06:10:52+00:00 Michael A. Sherbon <p>The golden ratio is found to be related to the fine-structure constant, which determines the strength of the electromagnetic interaction. The golden ratio and classical harmonic proportions with quartic equations give an approximate value for the inverse fine-structure constant the same as that discovered previously in the geometry of the hydrogen atom. With the former golden ratio results, relationships are also shown between the four fundamental forces of nature: electromagnetism, the weak force, the strong force, and the force of gravitation.</p> 2019-10-22T05:39:08+00:00 Copyright (c) 2019 Michael A. Sherbon The Inverse Precise Placement of Numbers Based at Pythagoras 1:3 and the Precise Configuration of Numbers as the Basis of a Unified Theorem That Binds the Physics of Mass, Space, Energy and the Torque Power (Inertia) That Sustains the Finite Universe. 2019-11-01T04:53:33+00:00 Vinoo Cameron <p>This paper is based on the precise inverse cone of Pythagoras 1:3. As in section 1 of this paper, all mathematics presented in this paper is by precise &nbsp;mathematics equations and the author has maintained by proof that the base numbers constant from which all physics constants can be derived are -1 to 19 ( the value 6 is&nbsp; as per this paper is the constant for expansion of&nbsp; all bounded space and 19 is the patent “end value” of the base constant numbers as shown in section 1 and &nbsp;referenced in this section11). Numbers <em>as created</em> and as placed at the cone of Pythagoras 1:3 are precise manifestation of the numbers of linear composite. However, this paper shows that the invention of designated angles (Trigonometry) is an approximate arbitrary arrangement invented by man, based on the created fixed angle of 90 degrees and is certainly flawed as shown here in this paper. Likewise, any attempts to measure curvature by linear numbers is fraught with much error. The author maintains that “If the atomic density and structure of &nbsp;meteorites from far space have the same configuration as those found on this earth, then by all created logic , these numbers configuration presented in&nbsp; these two papers and the book (The God of Papa Einstein and Sir Isaac Newton) are a constant unified theorem of &nbsp;all the space and mass ( &nbsp;Quantum mechanics) in the universe”. Einstein’s Theory of relativity and all other interstellar phenomena are not addressed in the context of this paper because all this is observed science phenomena and not a physical science, and this paper deals with precise numbers configuration as in the section 1 of the paper. Einstein’s relativity is a <em>real observed natural phenomenon</em>, not science by itself, it is a natural aberration of the fact that observed relativity is due to inherent curvature and linear relationship between any two points in the universe and because of the spiral progression of curved space. Neither does light bend it appears to bend, nor does time really dilate in real terms even though it is a real observed phenomenon, neither numbers or distances dilate by any continuum, unfortunately, that is why Einstein’s misconception about time dilation is a Theory and will always be Theory.</p> 2019-10-28T00:00:00+00:00 Copyright (c) 2019 Vinoo cameron Sense and Motion: The Barrier Preventing Us from Understanding Motion 2019-11-01T08:26:01+00:00 Aaron Fu <p>Currently, scientific study and advancements are at odds with the natural motion systems that surround us. This paper explores how it is our sensory form and the cognition developed upon this sensory form that creates a barrier preventing us from truly understanding the laws of motion. It begins by isolating and defining two distinct forms of information and information processing mechanisms: motion information and integrated information. From this new perspective, it then explains how our sensory system is necessarily based on an integrated information mechanism to support basic survival needs, but is essentially blind to the true features of motion.&nbsp; The far-reaching effects of this discovery include the limitations within our cognitive mode and the current methods of scientific study and development.</p> 2019-10-30T10:53:38+00:00 Copyright (c) 2019 Aaron Fu Study The Influence of The Number of Beams on Radiotherapy Plans for The Hyopfractionated Treatment of Breast Cancer Using Biological Model 2019-11-04T10:20:19+00:00 Z.

Abdel Hamid Possible Explanation of the Quark Confinement and Asymptotic Freedom, and Possible Solution to the Yang-Mills Mass Gap Problem 2019-11-04T08:14:25+00:00 Antonio Puccini <p>With this work, we try to answer 3 fundamental questions that have plagued mathematicians and physicists for several decades. As known, the spontaneous symmetry breaking (SSB) and the Brout-Englert-Higgs Mechanism (BEH-M) solved the Yang-Mills Mass Gap Problem. However, various mathematicians, even prestigious ones, consider the basic assumptions of the gauge theories to be wrong, as well as in conflict with the experimental evidences and in clear disagreement with the facts, distorcing the physical reality itself. Likewise, the Quantum Fields Theory (QFT) is mathematically inconsistent, adopting a mathematical structure somewhat complicated and arbitrary, which does not satisfy the strong demands for coherence. The weakest point of the gauge theories, in our opinion, consists in imposing that all the particles must be free of an intrinsic mass (massless).</p> <p>On the contrary, even for the particle considered universally massless, i.e. the photon (P), our calculations show a dynamic-mass, a push-momentum (p) of 1.325⋅10−22[g⋅cm/s]. That is, an optic P hits a particle with an energy-mass greater than 100 protons rest-mass’. It is clear that if we replaced this value with the full value of the P inserted in the equations of the Perturbation Theory, QFT and Yang-Mills theories, all divergences, that is all zeroes and infinities, would suddenly disappear.</p> <p>Consequently, the limits imposed by the SSB disappear so that there is no longer any need to deny the mass to the Nuclear Forces bosons, including the Yang-Mills b quantum. Still, the photons (Ps) are the basis of the quantum vacuum energy, which is distributed ubiquitously, also within the intra-atomic spaces. It is likely that a lot of Ps were trapped in atomic nuclei (at the time of nucleosynthesis) and among quarks (Qs) at the time of primordial nucleonic synthesis. We believe that when Qs get too close to each other, till repelling each other (Asymptotic Freedom of Qs), this may depend on the presence of a multitude of Ps that, no further compressible, begin to exert an antigravity repulsive force, just as a Dark Energy. This limit to Compressibility (C) of the radiation is shown in equation: PV 4/3 = C, where V is the volume, and P is the Pressure of the photonic gas. Quantum Mechanics plays a crucial role, through the Uncertainty Principle, in the spatial Confinement of Qs, which have remained eternally confined in an extremely narrow space by the&nbsp; Strong Interaction, but in primis by the very short range (likely ≈8.44[±1.44]⋅10-16cm) and lifetime of gluon(G) which, from our calculations, is ≈2.73[±0.564]⋅10-26 sec. Therefore, a new parameter may be added to the Qs and G spatial Confinement: the b quantum or G Temporal Confinement (and of their Colours and anti-Colours).&nbsp;</p> 2019-11-04T07:20:07+00:00 Copyright (c) 2019 Antonio Puccini The Algorithm of Information and the Origin of Basic Particles 2019-11-07T06:51:29+00:00 Bhekuzulu Khumalo <p>Everything is information because everything will inform you about itself through our senses, there is no other way to say it when discussing the philosophy of science. All information has similar basic characteristics including randomness. The reality of randomness gave the concepts to the theory of the algorithm of information the basis of all degrees of randomness. Everything is about relationships; the algorithm of information is the tool existence uses to determine the chances of relationships. If everything is about relationships, then relationships must begin with the particles. Not the basic particles having relationships with other basic particles as it was first postulated. The basic particle itself must be the result of an event and thus a relationship, it was not always there. This paper aims to shed some light on the question of where do particles come from? What relationships led to the event that created elementary particles?</p> 2019-11-07T06:05:51+00:00 Copyright (c) 2019 Bhekuzulu Khumalo Random Stability of Quadratic Functional Equations 2019-11-09T08:47:26+00:00 Mee Kwang Kang <p>In this paper, we investigate the generalized Hyers-Ulam stability on random -normed spaces associated with the following generalized quadratic functional equation <img src="/public/site/images/editor/8373_11.PNG"><img src="/public/site/images/editor/8373_2.PNG">,where &nbsp;is a fixed positive integer via two methods</p> 2019-11-09T08:46:26+00:00 Copyright (c) 2019 Mee Kwang Kang
