Where from Mass Came in the Universe? Did the Mass Originate from a Zero Rest Mass less Particle in Higgs Field
Abstract: A very interesting hypothesis based upon the possibility of a “Zero Rest Mass Particle in Higgs Field” in the Universe is described in this study. This is review of some hypothesis on mathematical basis on possibility of zero rest mass particles in the earliest moments of the Big Bang where Higgs Particles fused to give mass in Higg’s Scalar Field. The hypothesis is validated and considered the same truly correct …

Parameter Identification of Vibrating MIMO Mass-Spring-Damper Mechanical Systems with Coulomb Friction
Abstract: This study presents a time-domain method for identifying parameters in multi-degree-of-freedom (DOF) linear mass-spring-damper systems that include Coulomb friction, where the friction coefficient varies within a limited range, using measurements of position and control force. For mass identification in single-degree-of-freedom (DOF) vibrating mechanical systems with stiffness and no damping but Coulomb friction, the friction term is eliminated by first derivative processing. In addition, the identification of the coefficient of friction …

Democracy and Gasset’s ‘The Revolt of the Masses’: An Exposition
Abstract: Democracy simply put, is the government of “the people”. There is no doubt that the rise of “the people” is now a principal political force in our contemporary world. Though democracy is largely celebrated today, Ortega y Gasset, in his book Revolt of the Masses thinks that it is an unfortunate incident. For him, the masses, regrettably, are vulgar. The masses are drunken by the possibilities that contemporary science has …

Unified Mass–Energy Dissolution Cosmology (UMEDC): A Staged Framework for Cosmic Energy Transformation and Late-Time Acceleration
Abstract: The ΛCDM model successfully describes the universe’s expansion but remains fundamentally descriptive: it assigns fixed densities to matter, dark matter, and dark energy without providing a unifying physical mechanism behind their coexistence or evolution. In this work, we introduce the Unified Mass–Energy Dissolution Cosmology (UMEDC), a novel framework based on the staged transformation M → DM → DE, where ordinary matter gradually dissolves into a dark-matter-like reservoir, which subsequently transforms …

Development and Validation of Liquid Chromatography-Tandem Mass Spectrometric Method for Assay of Zidovudine in Human UrineDevelopment and Validation of Liquid Chromatography-Tandem Mass Spectrometric Method for Assay of Zidovudine in Human Urine
Abstract: A sensitive and selective liquid chromatographic-tandem mass spectrometric (LC-MS-MS) method was developed to determine zidovudine (ZDV) in human urine. After solid-phase extraction with SPE cartridge, the urine sample was analyzed on a C18 column (Symmetry 3.5 µm; 75×4.6 mm i.d) interfaced with a triple quadrupole tandem mass spectrometer. Positive electrospray ionization was employed as the ionization source. The mobile phase consisted of water-acetonitrile (20:80, v/v).The method was linear over a …

Study on the Method of Calculation of the Additional Mass of Parachute
Abstract: As is well known, the air drag experienced by a parachute when it is open is one of the important parameters that must be taken into account in studying the parachute opening process. If this term is not calculated correctly, it can have a negative effect on the parachute canopy, and may lead to errors in the number of parachute strings, the nominal diameter of the parachute, and the material …

Dalk (massage): A Remedial Therapy for Waja Uz Zahr (Low Back Pain)
Abstract: Dalk (Massage) is one of the oldest forms of remedial therapy, It is a universal method that is potentially applicable in all reflex changes produced by pain (nociceptive stimuli). It is pleasurable, routinely brings relief and is therefore also very popular with patients. Massage has the potential to influence emotion, biochemistry and biomechanics, usually without adding excessively to the adaptation load, and is therefore uniquely placed to be able to …

The Effect of Dynamics and Mass Transfer Limitation on the Kinetic Growth Rate of Methane Gas Hydrates
Abstract: Hydrate management aims to prevent impediments to fluid flow in pipes caused by hydrate deposition. To achieve this goal effectively, a comprehensive understanding of the thermodynamics and kinetics of hydrate formation is essential for predicting their equilibrium conditions, quantifying the amount of deposition, and estimating the associated risk. Hydrate growth studies are a relatively new field, and independent laboratory experiments have shown that hydrate growth is controlled by heat transfer, …

Interference Effect Analysis of Pilot Contaminated Massive MIMO Downlink with Different Pre-coders and Channel Estimation
Abstract: A new idea in cellular MU-MIMO is the use of large numbers of BS antennas to serve several single-antenna terminals simultaneously. In multi-cell environments, adjacent cells using the same spectrum cause a pilot contamination problem and degrade signal quality. This pilot overhead can be reduced by reusing pilot sequences in nearby cells; however, this potentially introduces interference in the channel estimation phase, the so-called "pilot contamination" effect. The achievable rate …

Design and Analysis of MEMS based Piezoelectric Accelerometer Having Square Shaped Proof Mass
Abstract: In any spacecraft launching program, the most prominent issue is to locate the spacecraft or satellite, in particular orbit of any particular planet. Now, while making the position of that spacecraft in space, abrupt changes in velocity occur and these velocity changes can break the controlling circuitry of the system since the velocity changes occur at very high environmental pressure. The designed device converts the deflections due to mentioned pressure …
