Research ArticleOpen accessIn the keywordsIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,452 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluating the Impact of Topography on Flooding in Owerri North, Imo State, Nigeria Using GIS and Remote Sensing TechniquesSylvanus Ibeabuchi IroThe aim of this study is to analyze the topographical contribution to floods in Owerri, North Imo State, Nigeria. Research was carried out to ascertain whether topographical elements played a role in the flooding in specific areas of Owerri North. As a result, very little research has looked at the effects of topography on flooding. Thus, there is a barrier … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 29 Jan 2025 · 7,197 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOne can Achieve the Nuclear Fission Reaction of Lithium by Accelerated Hydrogen Nuclei or NeutronsRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuThe idea circulated among physicists that in the upper area of the physical elements the fission reaction can be obtained and in the lower one the fusion reaction occurs. In the presented paper we want to impose another rule, namely the obtaining in the lower part of the physical elements of the fission and fusion nuclear reactions, with the obvious … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 7 Sep 2021 · 9,516 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHydrogen is a Friend, or an Enemy, of the Environment?Relly Victoria Virgil Petrescu, Raffaella Aversa, Taher M. Abu-Lebdeh et al.Hydrogen is the best friend of man and the environment. Actually, it is the core element from that can extract energy, at infinity, in various forms. Until now has not been sufficiently exploited, but once with the evolution of the human species is the time to start to pool all types of energy which the hydrogen and its isotopes may … …Energy Research Journal, Vol. 9, Issue 1 · 6 Feb 2019 · 7,029 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInvolvement of Bone Marrow Megakaryocytes in the Formation of the Bone Marrow-Blood Barrier in Transgenic MicePawel Laskowski, Karol Ostrowski, Beata Klim et al.Mature cell release takes place through the hypothetical barrier- the bone marrow-blood barrier. It consists of blood vessels and cells that surround them. Such cells are, among others, megakaryocytes. They are involved in the release of platelets or other cellular components of blood. The amount and the development of megakaryocytes and thus the maturity of barrier depends on many factors. … …American Journal of Pharmacology and Toxicology, Vol. 8, Issue 3 · 19 Sep 2013 · 7,180 accessesView PDF Cite
