Materials Science and Engineering Faculty Research & Creative Works

The deformation behavior of friction stirs processed magnesium alloy with average grain size ranging from 25 μm to 240 nm was studied. an evaluation of critical grain size for transition of deformation mode from twinning to slip was carried out by employing tensile and compressive tests. the role of critical grain size in transition of deformation behavior from strain hardening to softening was established. Inhomogeneous yielding was observed during tensile test of ultrafine-grained magnesium alloy below the critical grain size. © 2012 Elsevier B.V.

Understanding Dyslexia In Children Through Human Development Theories, Thuraya A. Al-Shidhani, Vinita Arora

Sultan Qaboos University Medical Journal

Dyslexia is a specific learning disability that is neurological in origin, with an estimated overall worldwide prevalence of 5–10% of the population. It is characterised by difficulties in reading, accuracy, fluency, spelling and decoding abilities. The majority of publications reviewed indicated that screening is performed at the preschool level. Screening can also be conducted at birth or the first year of life. Understanding human development theory, for example, Piaget’s human development theory, may help determine at which stage of childhood development dyslexia is more detectable, and therefore guide the management of this disability. The objective of this review is to …

Nodular Melanoma Mimicking Keratoacanthoma : Lessons To Learn, Leelavathi Muthupalaniappen, Srijit Das, Norazirah Md Ali, Siti Am

Sultan Qaboos University Medical Journal

A 67-year-old man of Chinese descent presented with a painless nodular lesion that had been present on his right forearm for the previous 3 months. A single, well-defined, dome-shaped, firm nodule with a central keratin plug surrounded by erythema was noted. Keratoacanthoma with secondary bacterial infection was suspected and the patient underwent an excision biopsy. Biopsy of the nodule and immunohistochemical staining supported a diagnosis of nodular malignant melanoma. It should be noted both that nodular malignant melanoma may present with a wide variety of clinical appearances, and that the lack of melanin pigment in nodular malignant melanoma may hinder …

Spectroelectrochemical Elucidation Of The Kinetics Of Two Closely Spaced Electron Transfers, Robert L. Keesey, Michael D. Ryan

Chemistry Faculty Research and Publications

The use of spectroelectrochemistry to facilitate the analysis of an EE mechanism was reported in this work. Using a set of spectra as a function of potential, the spectra of all three oxidation states were determined using evolving window factor analysis. From these spectra, the concentration of each species in solution was determined for each potential. Using these data, the current was calculated. Unlike the direct measurement of current, the current due to each redox process was determined, allowing one to analyze each redox process separate from the other. With the use of the Butler–Volmer equation, the redox potential and …

Rehearsal Guide: An Analysis Of The Music, History, Teaching Considerations And Professional Recordings Of Choral Literature For Male Chorus, Robert J. Graham Ii

Research Papers

As a choral conductor, there are several factors to take into consideration when programming literature for the choral ensemble. These factors will influence the methods one will use in teaching this literature, informing the conductor of all the necessary information he or she needs to bring the score to life. One must consider the historical era in which the piece was composed, the background on the composer and poet, as well as have an understanding of the general characteristics of its style. One must observe the range and tessitura of the piece and determine if the ensemble is technical capable …

What (If Anything) Do We Owe Wild Animals?, Clare A. Palmer

Between the Species

It’s widely agreed that animal pain matters morally – that we shouldn’t, for instance, starve our animal companions, and that we should provide medical care to sick or injured agricultural animals, and not only because it benefits us to do so. But do we have the same moral responsibilities towards wild animals? Should we feed them if they are starving, and intervene to prevent them from undergoing other forms of suffering, for instance from predation? Using an example that includes both wild and domesticated animals, I outline two contrasting ways of thinking about our moral responsibilities with respect to assisting …

Stress- And Sex-Related Differences In The Activation Of Neuronal Subtypes In The Basolateral Amygdala Of The Rat, Alejandra E. Lopez, Christina C. Ruiz, Juan M. Bolanos, Jameel N. Hamdan, Kristin Gosselink

COURI Symposium Abstracts, Summer 2012

Previous studies suggest that stress alters the activational profiles among phenotypically-distinct subpopulations of neurons within the basolateral amygdala (BLA) of the rat. Given the connectivity of this region of the brain to the hippocampus, and the implications of the role of the BLA in modulating long-term potentiation associated with memory and learning, inferences of stress having a negative impact on cognition and memory can be drawn. Observations regarding stress response disparities between males and females in our model prompted the investigation of the role gender plays in cognition under conditions of stress, as well as the responses to stress itself. …

Transition States Of Dbt Molecule At The Mos2/Co9s8 Interface: First Principles, Svetlana Gelpi, Alvaro S. Laham, Gilles Berhault, Brenda Torres, Russel R. Chianelli, Manuel Ramos *

COURI Symposium Abstracts, Summer 2012

Sulfur removal in crude oil, is one of most important application when designing catalytic material to target hydrodesulphurization reactions. This particular study comprehends the quantum computational calculations for the transitional states during the HDS reaction in the molecular model of MoS₂/Co₉S₈, which is a theoretical molecular model to describe the synergic contact between both crystallographic structures. Results produced using the exchange correlation Perdew-Burke-Ernzerhof(PBE) functional indicate the existence of endothermic and exothermic transitions during the attachment of DBT molecules. In addition, it proves that promotion (addition of Co, Ni) provokes the electronic configuration of electron …

Is Africa Semper Aliquod Novi?, Maybelle Botha

Proceedings of the IATUL Conferences

I chose to paraphrase Pliny's famous remark about there always being something new out of Africa as a title for this brief overview of information technologies in Southern Africa, because I would like to illustrate that we on the Southern point of Africa are not as isolated as we or the rest of the world sometimes imagine . I will also try to show that we are also there when it comes to something new.
