Research ArticleOpen accessPhrase in the titleShift 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 accessPhrase in the titleImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNew Solution for Reducing Doppler Shift in the MB-OFDM System Over High Mobility Multipath Channel for V&I CommunicationSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.The MB-OFDM has been proposed as a good candidate to ensure Vehicle to Infrastructure communication (V&I). Fast moving vehicles present challenges for the proposed system especially for high mobility (250 km h-1). The main objective in this study is to study and investigate the impact of Doppler shift on the quality of transmitted/received signal in terms of Bit Error Rate … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 29 Apr 2015 · 7,170 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphological Changes in Brain Tissue During Experimental HypoxiaAizhan Mussayeva, Ulbossin Kozhaniyazova, Laura Koibasova et al.The extensive application of hypoxic training to enhance cerebral circulation highlights its significant role in effectively realizing the therapeutic and health-promoting benefits of this method. The discrepancy between the data on the features of cerebral circulation and cellular metabolism in brain tissues during circulatory hypoxia and significant interest in the physiological patterns of the integrative response of the body determined … …OnLine Journal of Biological Sciences, Vol. 25, Issue 4 · 20 Feb 2026 · 1,552 accessesView PDFCite
Research ArticleOpen accessIn the abstractColor Doppler Evaluation of Isovolumetric Relaxation Time and of Signals Arising from Axons of the Median Nerve as a Means to Evaluate Mitochondrial Functionality in the Context of Immunotherapy of Cancer and Chronic Conditions Associated with Mitochondrial DysfunctionStefania Pacini, Marco RuggieroReactive Oxygen Species (ROS) arising from the disruption of mitochondrial respiration act as endogenous mutagens and tumor promoters. When production of ROS exceeds the capacity of DNA repair mechanisms, random mutations and aneuploidy ensue, thousands of genes become unbalanced and genetic/epigenetic chain reactions lead to progressive aneuploidy with only two outcomes: karyotypes so altered that are not viable or karyotypes … …American Journal of Immunology, Vol. 15, Issue 1 · 12 Oct 2019 · 9,690 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethadone and Dexmedetomidine Combination as Premedicant Agents for Ovariectomy in CatsH. Tayari, I. Vannozzi, G. Breghi, A. BrigantiThe purpose of this study was to assess sedative and analgesic effects produced by the association of methadone and dexmedetomidine, administered intramuscularly as premedication for ovariectomy in cats. Twenty-four healthy cats were enrolled in the study. The values of heart and respiratory rate were recorded as Tbase. Cats received methadone 0.5 mg kg-1 and dexmedetomidine 5 mcg kg-1 IM. Sedation … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 2 · 27 Jun 2015 · 8,400 accessesView PDFCite
Research ArticleOpen accessIn the abstractREVIEW OF GRAVITATIONAL WAVE DETECTIONS: DYNAMICAL SPACEReginald Thomas CahillThis is a review of the numerous successful gravitational wave detections and the implications for the nature of space and time. The prevailing space time paradigm in physics was founded on the putative "null" results of the Michelson-Morley (MM) 1887 interferometer experiment to detect light speed anisotropy and which resulted in two different new relativity theories: Lorentz relativity (Lorentz, 1904) … …Physics International, Vol. 5, Issue 1 · 27 Mar 2014 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractANALYSIS AND SOLUTION FOR MULTI-BAND ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING ULTRA WIDE BAND SYSTEM IN REAL ENVIRONMENT FOR VEHICLE TO INFRASTRUCTURE APPLICATIONSanaa Kabil, Raja Elassali, Fouzia Elbahhar et al.Many researches in the world deal with driving on the road to ensure optimum safety. In this context, several telecommunication technologies are often used to connect the vehicles via continuous wireless communication with the infrastructure, exchange data and information relevant to increase overall road safety and enable cooperative traffic management. These systems are not reliable for all situations and the … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractDYNAMICAL 3-SPACE: NEO-LORENTZ RELATIVITYReginald Thomas CahillThe major extant relativity theories-Galileo’s Relativity (GaR), Lorentz’s Relativity (LR) and Einstein’s Special Relativity (SR), with the latter much celebrated, while the LR is essentially ignored. Indeed it is often incorrectly claimed that SR and LR are experimentally indistinguishable. Here we show that (i) SR and LR are experimentally distinguishable, (ii) that comparison of gas-mode Michelson interferometer experiments with spacecraft … …Physics International, Vol. 4, Issue 1 · 17 Jul 2013 · 6,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Coastal Current of the Andaman Sea Revealed by Reprocessed ObservationsSakharin Suwannathatsa, Prungchan Wongwises, Worachat Wannawong, Suphat VongvisessomjaiProblem statement: The surface currents in the Andaman Sea are observed and quantified by many studies in opposite of the local coastal current that is unclear. Knowing the contributor to this local current improves the simulation work in the most accurate way. This study reviews reprocessed observations from satellites and creates an oceanic model by taking data of 1995 to … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 22 May 2012 · 7,067 accessesView PDFCite
