A Multicultural Comparison of Engineering Students

A multicultural personality profile of engineering students is presented in this work. The Myers-Briggs Type Indicator (MBTI) was used as an instrument to sort personality types of engineering students at both King Fahd University of Petroleum and Minerals in Saudi Arabia and University of Western Ontario in Canada. The paper discusses the diferences and similarities in the personality profile of Saudi and Canadian engineering students and its implications for engineering education in the light of the MBTI scales

Unsupervised Learning: Using Educational Videos as a Learning Tool to Enhance the English Vocabulary Use for the I-Generation

Words are the foundation that we need to build our meaning on therefore without vocabulary one cannot communicate properly or create a single comprehensible conversation Ghazal 2007 p 84 Furthermore Bowen and Marks 2002 describe vocabulary as follows words are the base of language which makes them the base of communication indicating the pivotal role of vocabulary knowledge in second language acquisition as cited in Ebrahimzadeh 2017 p 1 Consequently not having an adequate amount of vocabulary leads to a deficiency in language production Ebrahimzadeh 2017 p 1 This paper aims to highlight the most salient studies that are related to enhance the new generation of EFL students vocabulary attainment through the use of educational videos outside the classroom settin

A Multicultural Comparison of Engineering Students: Implications to Teaching and Learning

Problem statement: Personality considerations have become increasingly important in recent years, but studies involving the personality characteristics of engineers have been scarcely reported. Engineers today are expected to have a broader range of skills than in the recent past because users are now equally concerned with the technical as well as the personal services provided by engineers. Approach: A multicultural personality profile of engineering students had been presented in this study. The MBTI was used as an instrument to sort personality types of engineering students at both King Fahd University of Petroleum and Minerals in Saudi Arabia and University of Western Ontario in Canada. Results: The study had discussed the differences and similarities in the personality profile of Saudi and Canadian engineering students and its implications for engineering education in the light of the MBTI dimensions. Although there had been some teaching strategies useful to a whole class, the personality differences among engineering students made it necessary for instructors to diversify those teaching strategies. Conclusion/Recommendations: Adjusting instruction to accommodate the learning styles of different types of students had increased both achievement and enjoyment of learning. Hence, this study had improved the degree of understanding among teachers and engineering students

Geochemical Signature of Mesozoic Volcanic and Granitic Rocks in Madina Regency Area, North Sumatra, Indonesia, and Its Tectonic Implication

Http://dx.doi.org/10.17014/ijog.vol4no2.20094Five samples consisting of two Permian-Triassic basalts, two Triassic-Jurassic granitic rocks, and a Miocene andesite were collected from the Madina Regency area in North Sumatra that is regionally situated on the West Sumatra Block. Previous authors have proposed three different scenarios for the geological setting of West Sumatra Permian Plutonic-Volcanic Belt, namely an island-arc, subduction related continental margin arc, and continental break-up. Petrographic analysis of the Mesozoic basaltic samples indicates that they are island-arcs in origin; however their trace element spider diagram patterns (Rock/MORB ratio) also show the character of back-arc marginal basin, besides the island-arc. Furthermore, their REE spider diagram patterns (Rock/ Chondrite ratio) clearly reveal that they were actually generated in a back-arc marginal basin tectonic setting. Meanwhile, the two Mesozoic granitic rocks and the Miocene andesite reflect the character of an active continental margin. Their spider diagram patterns show a significant enrichment on incompat- ible elements, usually derived from fluids of the subducted slab beneath the subduction zone. The high enrichment on Th makes their plots on Ta/Yb versus Th/Yb diagram are shifted to outside the active continental margin field. Although the volcanic-plutonic products represent different ages, their La/Ce ratio leads to a probability that they have been derived from the same magma sources. This study offers another different scenario for the geological setting of West Sumatra Permian Plutonic-Volcanic Belt, where the magmatic activities started in a back-arc marginal basin tectonic setting during the Permian-Triassic time and changed to an active continental margin during Triassic to Miocene. The data are collected through petrographic and chemical analyses for major, trace, and REE includ- ing literature studies

SrCo1−xTixO3−δ perovskites as excellent catalysts for fast degradation of water contaminants in neutral and alkaline solutions

Perovskite-like oxides SrCo1−xTixO3−δ (SCTx, x = 0.1, 0.2, 0.4, 0.6) were used as heterogeneous catalysts to activate peroxymonosulfate (PMS) for phenol degradation under a wide pH range, exhibiting more rapid phenol oxidation than Co3O4 and TiO2. The SCT0.4/PMS system produced a high activity at increased initial pH, achieving optimized performance at pH  ≥ 7 in terms of total organic carbon removal, the minimum Co leaching and good catalytic stability. Kinetic studies showed that the phenol oxidation kinetics on SCT0.4/PMS system followed the pseudo-zero order kinetics and the rate on SCT0.4/PMS system decreased with increasing initial phenol concentration, decreased PMS amount, catalyst loading and solution temperature. Quenching tests using ethanol and tert-butyl alcohol demonstrated sulfate and hydroxyl radicals for phenol oxidation. This investigation suggested promising heterogeneous catalysts for organic oxidation with PMS, showing a breakthrough in the barriers of metal leaching, acidic pH, and low efficiency of heterogeneous catalysis

Directed Evolution of an Artificial Imine Reductase

Artificial metalloenzymes, resulting from incorporation of a metal cofactor within a host protein, have received increasing attention in the last decade. The directed evolution is presented of an artificial transfer hydrogenase (ATHase) based on the biotin-streptavidin technology using a straightforward procedure allowing screening in cell-free extracts. Two streptavidin isoforms were yielded with improved catalytic activity and selectivity for the reduction of cyclic imines. The evolved ATHases were stable under biphasic catalytic conditions. The X-ray structure analysis reveals that introducing bulky residues within the active site results in flexibility changes of the cofactor, thus increasing exposure of the metal to the protein surface and leading to a reversal of enantioselectivity. This hypothesis was confirmed by a multiscale approach based mostly on molecular dynamics and protein-ligand dockings
