Research ArticleOpen accessEvery word in the titlePhysics Models of Pronuclear Movements in EggsKang Cheng, Changhua ZouBased on published experimental data, Newton's laws, and Coulomb's law, we investigate natural and normal pronuclear movements in wild types of eggs and develop physics models to fit the experimental data quantitatively. The difference between our modeling calculated results and the experimental data is less than 20%. Our models explain why and how pronuclei move in even or in variant … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,743 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of an Enhanced (G'/G)-Expansion Method to Find Exact Solutions of Nonlinear PDEs in Particle PhysicsS.M. Rayhanul IslamThe enhanced (G'/G)-expansion method is very effective and powerful method to find the exact traveling wave solutions of nonlinear evolution equations. We choose the Phi-4 equation to illustrate the validity and advantages of this method. As a result, many exact traveling wave solutions are obtained, which include soliton, hyperbolic function and trigonometric function solutions. …American Journal of Applied Sciences, Vol. 12, Issue 11 · 13 Nov 2015 · 7,037 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvolution of Time Concept in Physics and in PhilosophyC. Sivaram, Kenath Arun, O. V. KirenWhat is ’time’? This is a question that has perplexed many a physicist and philosophers alike. The perception of the passage of time appears ingrained in all biological systems where growth, evolution and decay of objects, etc. are measurable indicators of the passage of time. Here we look at various physical models of time, from Newtonian to relativistic. We also … …Physics International, Vol. 6, Issue 2 · 9 Jul 2015 · 8,957 accessesView PDFCite

Research ArticleOpen accessIn the keywordsEarly Greek Astrophysics: The Foundations of Modern Science and TechnologyXenophon MoussasThe foundations of modern science and technology, metrology, experimental physics, theoretical physics, theoretical mathematics, astrophysics, including applied optics and spectroscopy go back to the Prehistoric, Presocratic, Classical and Hellenistic Greece. This tradition is well deep rooted in time, going back mainly to the epoch of the prehistoric Aegean sea, the mainland of Greece and the Islands, Cycladic, Euboea, as well … …Space Science International, Vol. 1, Issue 2 · 4 Feb 2014 · 8,679 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Rise of the Physical Sciences in “Stricto Sensu” The Developmental Approach and the History of SciencesGeorg W. OesterdiekhoffJ. Piaget dedicated several books and articles on the psychogenetic reconstruction of the history of sciences. A couple of disciples followed Piaget´s ideas and reconstructed the history of single disciplines or of some scientific developments in terms of developmental psychology. They found a striking similarity between childish psychological stages and the sciences in their premodern period. Correspondingly, they also found … …Physics International, Vol. 8, Issue 1 · 31 Oct 2017 · 8,636 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDiscovering Nature’s Hidden Relationships, an Unattainable Goal?James R. JohnsonDiscovering hidden relationships, relationships that may reveal the secrets of nature, is a difficult if not impossible goal. This is primarily because the models of the two worlds, the Standard Model of Particle Physics (SMPP) and the Standard Model of Cosmology (SMC) have no elements in common, they are completely disjoint. Thus, relationships are hidden and finding them, may prove … …Physics International, Vol. 6, Issue 1 · 13 Aug 2015 · 7,877 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegration of Quantum Cryptography through Satellite Networks TransmissionSkander Aris, Abderraouf Messai, Malek Benslama et al.Problem statement: The security of the telecommunications satellite has become a crucial issue. The telecommunications can be set using the classical cryptography. But this so-called classical cryptography provides cryptographic security. This means that security is based on the difficulty of some mathematics problems. On the other hand, quantum cryptography provides security without conditions based on the law of quantum physics. … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,516 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,365 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresenting a New Equation that Accurately Determines the Size of a Moving Elementary ParticleFlorian Ion Tiberiu PetrescuThe paper briefly presents a new Eq. (9). The role of Eq. (9) is to accurately determine the size of a moving elementary particle, depending on its velocity (or particle energy). Although Eq. (9) has a general character, it can be applied to any elementary particle in motion to determine the size of that particle, in the study, it was … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 24 Nov 2022 · 6,475 accessesView PDFCite
