Review ArticleOpen accessIn the abstractPermanent Magnetic FluidsNicolae Petrescu, Florian Ion Tiberiu PetrescuA team of researchers at the University of Massachusetts Amherst has accidentally obtained the first magnetized permanent liquid in the world, the droplets of this liquid moving in unison and able to associate in different forms while being manipulated exterior by means of a magnet, according to a new study published in the latest issue of the journal Science, reports … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 22 Aug 2019 · 8,842 accessesView PDFCite
Literature ReviewOpen accessIn the abstractA Short Communication: ‘Hasret’s Theory’; Quantum Observation Caused by the Filling of a Helium-3 Electron Hole in an INVIZICLOUD© via a ‘Celalettin-Field Quantum Observation Tunnel’Metin Celalettin, Horace KingIn anti-ferromagnetism, the magnetic moments of particles related to electron spin; a regular pattern, the remaining particles in the ensemble are like ferromagnetism; a manifestation of ordered magnetism. The attraction between a magnet and a ferromagnetic the quality of magnetism first apparent to the formation of the Earth 4 Billion years ago until today. Generally, antiferromagnetic order is directly proportional … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 29 Jul 2019 · 8,238 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,060 accessesView PDFCite
Research ArticleOpen accessIn the abstractGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,409 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA has Found the Most Distant Black HoleRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuScientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole. This matter-eating beast is 800 million times the mass of our Sun, which is astonishingly large for its young age. Researchers report the find in the journal Nature. "This black hole grew far larger than we expected in only 690 million years after the … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractParticle Size Determination in Rice Bran Testing with Various Levels of Rice Husks Using Ultrasonic WavesUrip Rosani, Iman Hernaman, Rahmat Hidayat, Darmawan HidayatThe principle of ultrasonic waves in detecting materials is based on their physical properties. The size of particles has an impact on various aspects of their composition and function. The limited information that reports the particle size of RH-contaminated RB samples tested using ultrasonic waves is the basis for this study. This study aims to determine the optimal sample particle … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 6 Nov 2024 · 4,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological and Structural Reaction of Avena sativa Seedlings to the Effects of Nano and Microparticles of ZincArailym Serikbai, Aidar Aitkulov, Anna Stanco et al.Kazakhstan has a well-developed mining and metallurgical industry, which produces macroand nanoparticles of heavy metals, including zinc emitted to the environment. The nanoscale particles have a different biological activity, which requires some additional research. The effects of various concentrations of zinc macroparticles and nanoparticles on the anatomical structure of oat seedlings (Avena sativa L.) and their accumulation in vegetative organs … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 9 Jul 2024 · 4,406 accessesView PDFCite
Review ArticleOpen accessIn the abstractOverview of Atherosclerotic Plaque: From Formation to ComplicationAnastasia Vladimirovna Poznyak, Varvara Alexandrovna Orekhova, Vasily Nikolaevich Sukhorukov et al.Atherosclerosis is a serious worldwide health problem. The pathogenesis of this disease is complex and includes a multilevel interaction of such processes as inflammation, endothelial dysfunction, mitochondrial dysfunction, and multiple modifications of lipid particles. With the increase in life expectancy, mankind is more and more often faced with the unpleasant consequences of atherosclerosis. Atherosclerosis is a precursor to serious health … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Mar 2024 · 5,393 accessesView PDFCite
Research NotesOpen accessIn the abstractTurbulent-Fluid-Based Simulation of Dynamic Liquefaction Using Large Deformation Analysis of Solid PhaseRohollah TaslimianTo accurately simulate the cyclic liquefaction phenomenon, it is necessary to establish a well-defined coupling between the solid particles and the high-velocity percolating pore fluid. For this purpose, the existing literature extensively examines large deformation liquefaction analyses for the solid phase, regardless of the fluid flow nonlinearity. On the other hand, the transient fluid pressure gradient governed by the turbulence … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 22 Feb 2024 · 6,015 accessesView PDFCite
