Research ArticleOpen accessIn the keywordsLow Cost Long Distance Detector for Explosives and Chemical Analysis by IEC ApplicationGeorge H. Miley, Heinrich Hora, Frederick Osman et al.A radiation source for detecting specific chemicals at several meter distances even behind walls, car doors or other barriers is the application of Million electron Volts (MeV) neutrons from nuclear fusion reactions at such low intensities to avoid any danger for human bodies. The chemical analysis consists in the neutron activation of nuclei emitting then gamma radiation of lines very … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractShift of Zeeman Components of Ionic Spectral Lines Caused by the Angular Doppler EffectEugene OksThe angular Doppler effect was introduced by Garetz. While the usual Doppler effect is caused by the translational motion of the emitter, the angular Doppler effect is caused by the rotational motion of the emitter. It results into the frequency shift of a circularly-polarized light. In the present paper we analyze the angular Doppler effect caused by the rotational motion … …Physics International, Vol. 15, Issue 1 · 16 Jun 2025 · 6,449 accessesView PDFCite
Research ArticleOpen accessIn the abstractElementary Structure of Matter can be Studied with New Quantum ComputersNicolae Petrescu, Florian Ion Tiberiu PetrescuMuch has been talked about quantum computers. Today they are working on difficult simulations, so we can already congratulate the college of researchers at the Oak Ridge National Laboratory as the world's first to successfully simulate an atomic nucleus using a quantum computer. The results that were published in the physical examination letters demonstrate the huge capacity of quantum systems … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 25 Jun 2018 · 7,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Proposed Solutions to Achieve Nuclear FusionRelly Victoria Virgil Petrescu, Aversa Raffaella, Samuel Kozaitis et al.Despite research carried out around the world since the 1950s, no industrial application of fusion to energy production has yet succeeded, apart from nuclear weapons with the H-bomb, since this application does not aims at containing and controlling the reaction produced. There are, however, some other less mediated uses, such as neutron generators. The fusion of light nuclei releases enormous … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 20 Jul 2017 · 8,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrations of Seismic Data, Petro-physical Evaluation and Reserve Estimation in Fimkassar Oil Field of Eastern Potwar, PakistanMuhammad Ishfaque, Hafeez Ur Rehman, Bilal Khalid et al.In upper Indus basin Potwar plateau is a successful exploration area for hydrocarbon. The study area is consisting of Fimkassar oil field and research data is obtained from Land Mark Resources with the special permission of Director General of Petroleum Concession Ministry of petroleum and natural resources Islamabad. The study area consists of well#1 and #2 and seismic lines 97-CP-07, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 13 Apr 2017 · 8,092 accessesView PDFCite
Research ArticleOpen accessIn the abstractKRETSCHMANN INVARIANT AND RELATIONS BETWEEN SPACETIME SINGULARITIES ENTROPY AND INFORMATIONIoannis Gkigkitzis, Ioannis Haranas, Omiros RagosCurvature invariants are scalar quantities constructed from tensors that represent curvature. One of the most basic polynomial curvature invariants in general relativity is the Kretschmann scalar. This study is an investigation of this curvature invariant and the connection of geometry to entropy and information of different metrics and black holes. The scalar gives the curvature of the spacetime as a … …Physics International, Vol. 5, Issue 1 · 28 Mar 2014 · 11,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractNUCLEAR DETONATION AROUND COMPACT OBJECTSC. Sivaram, Kenath Arun, O.V. KirenIn this study we explore the various aspects involved in nuclear detonations occurring around compact objects and the energetics involved. We discuss the possibility of sub-Chandrasekhar white dwarfs detonating due to the buildup of a layer of hydrogen on the CO white dwarf by accreting from a companion star to explain observed deviations such as subluminous type Ia. We also … …Physics International, Vol. 5, Issue 1 · 24 Mar 2014 · 8,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractTHORIA EHANCEMENT OF NUCLEAR REACTOR SAFETYBarbara Szpunar, Jerzy SzpunarThe recent nuclear accident in Fukushima demonstrates that a nuclear mishap should be viewed using interdisciplinary tools. For example, the urania fuel melts not only because of enhanced neutron flux but also because its thermal conductivity degrades when it oxidizes. Here we present the application of first principles calculations to evaluate the structural, mechanical and thermal properties of traditional urania … …Physics International, Vol. 4, Issue 2 · 20 Dec 2013 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Absorbed and Effective Dose from Natural Background Radiation around a Nuclear Research FacilityMuhammad Auwal Musa, Idris Isa Funtua, Simon Peter Malam, Abdullahi Suleiman ArabiProblem statement: This study presents result of outdoor absorbed dose rate and estimated effective dose from the naturally occurring radionuclides 232Th and 238U series 40K, around a Nuclear Research Reactor at the Centre for Energy Research and Training (CERT), Zaria, Nigeria. Approach: A high-resolution in situ γ-ray spectrometry was used to carry out the study. CERT houses a 30Kw Research … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeedup of Particle Transport Problems with a Beowulf ClusterZhongxiang Zhao, G. Ivan MaldonadoThe MCNP code is a general Monte Carlo N-Particle Transport program that is widely used in health physics, medical physics and nuclear engineering for problems involving neutron, photon and electron transport[1]. However, due to the stochastic nature of the algorithms employed to solve the Boltzmann transport equation, MCNP generally exhibits a slow rate of convergence. In fact, engineers and scientists … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Dec 2006 · 6,918 accessesView PDFCite
