Research ArticleOpen accessIn the keywordsThe Effect of Temperature and Acid Concentration on Corrosion of Low Carbon Steel in Hydrochloric Acid MediaAnees A. Khadom, Aprael S. Yaro, Abdul Amir H. Kadum et al.Problem statement: The effect of different temperatures and acid concentrations on the corrosion of low carbon steel in hydrochloric acid were addressed in this study. Approach: The effect of temperature was explained by application of Arrhenius equation and transition state theory, while the acid concentration effect was explained using reaction kinetic equations. The combined effect of temperature and acid concentration … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 11,473 accessesView PDF Cite

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 abstractCoaching for Monitoring Education Quality and Quality Assurance of Modular Education Program Based on Public-Private PartnershipDulma Tsyrendashiyevna Dugarova, Sesegma Zandaraevna Kimova, Natalia Anatolyevna KazachekA new stage in the development of quality management theory was the transition to knowledge management. Coaching is considered an important instrument of influence on the performance of individuals and the organization as a whole in terms of knowledge management. Modern management in the coaching style gives priority to look at employees as the main resource of the organization. The … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 9 Nov 2016 · 7,107 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTheoretical Study of the Proton Transfer in EnaminonesRita Sabah EliasProblem statement: Hydrogen bonding has a vital rule to unrevealed the nature of many different interactions both in gas phase and condensed media thus it is one of the most important concepts in chemistry. Enaminoes with their ability to form intrahydrogen bonded cheated rings represent one of the suitable compounds to study such concept. Approach: The three possible tautomers of … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,418 accessesView PDF Cite

Research ArticleOpen accessIn the abstractQuantum Mechanical Calculation of the Optical Absorption of Silver and Gold Nanoparticles by Density Functional TheoryElham Gharibshahi, Elias SaionProblem statement: Metal nanoparticles confine the motion of conduction electrons and exhibit a strong optical absorption of electromagnetic radiation in the UV-vis-NIR region. The absorption is classically derived from the collective oscillations of free electrons in a metallic nanostructure as a consequence of incident electromagnetic radiation polarizing the particle optically embedded in a dielectric matrix. These oscillations, known as the … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 16,181 accessesView PDF Cite
