Research ArticleOpen accessIn the keywordsEffect of Activation Energies on Thermal Explosion in the Interior of the EarthAmos Oladele PopoolaProblem statement: Literatures have shown that thermal processes in the interior of the earth and the classical thermal explosion are analogous and that combustion processes are characterized by ignition and explosion. The heat released during the thermal explosion that occurs in the interior of the earth requires more attention. Approach: The study investigated the role of activation energies ratio in … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 27 Jul 2011 · 7,283 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTransformity: The Dependence of the Laws of Physics on Higher-Dimensional Coordinate TransformationsPaul S. WessonIn unified field theories with more than four dimensions, the form of the equations of physics in spacetime depends in general on the choice of coordinates in higher dimensions. The reason is that the group of coordinate transformations in (say) five dimensions is broader than in spacetime. This kind of gauge dependence is illustrated by two examples: a cosmological model … …Space Science International, Vol. 1, Issue 2 · 10 Dec 2013 · 9,627 accessesView PDFCite
Research ArticleOpen accessIn the keywordsProcess Physics: Emergent Unified Dynamical 3-Space, Quantum and Gravity: A ReviewReginald Thomas CahillExperiments have repeatedly revealed the existence of a dynamical structured fractal 3-space, with a speed relative to the Earth of some 500 km sec-1 from a southerly direction. Experiments have ranged from optical light speed anisotropy interferometers to zener diode quantum detectors. This dynamical space has been missing from theories from the beginning of physics. This dynamical space generates a … …Physics International, Vol. 6, Issue 2 · 4 Aug 2015 · 8,518 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeficient Reasoning for Dark Matter in GalaxiesJames Q. Feng, C.F. GalloIn this universe, not all of the matter around us can be readily seen. The further an object is away from us and the less luminous it is, the less visible it becomes. Just by looking at an object is usually difficult, if not impossible, to tell the amount of mass it contains. But astronomers have been using the measured … …Physics International, Vol. 6, Issue 1 · 14 Sep 2015 · 8,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractPostnatal Muscle Growth and Allometry in Anatomical Regions of Russian Black-Pied Heifers and their Crosses With Hereford and Charolais Under Intensive RearingIvan Petrovich Prokhorov, Grigorii Sergeyevich Shekhovtsev, Yulia Vasilevna ShoshinaCrossbreeding dairy cattle with specialized beef breeds is an effective strategy to increase beef production, yet data on muscle growth patterns in crossbred heifers remain limited. This study aimed to evaluate the growth intensity and redistribution of muscle mass in anatomical regions of carcasses in Russian Black-Pied heifers and their crosses with Hereford and Charolais breeds. A scientific experiment was … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 2 · 10 Aug 2026 · 923 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrajectory Optimization for First Human Asteroid Exploration MissionAtiksha Sharma, Santosh KosambeAfter the successful completion of robotic expeditions on Mars, an ultimate goal was set for space fairing nations and agencies around the world to send astronauts to Mars by 2030. Unfortunately, a mission to Mars would last upwards for years meanwhile several asteroids fly close to the Earth. A manned trip to an asteroid would be a valuable stepping stone … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 8 Aug 2020 · 6,435 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hypothesis Which Supports the Possibility of the Existence of Dark Matter with Negative MassFlorian Ion Tiberiu PetrescuThe paper presents an algorithm for calculating the negative mass of an atomic electron, a fact that from a physical point of view shows the possibility of the existence of the matter with the negative mass that could constitute the dark matter that separated from the normal matter with the positive mass due to the huge masses of different matter … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 Jan 2020 · 7,923 accessesView PDFCite
