The direct access model of hemispheric asymmetry was tested in a letter reflection (normal of reflected) judgement task. In the baseline condition letters were presented in their upright orientation, and reaction times were faster to letters presented in the right visual field than to those presented in the left visual field. In two other conditions the slides, and thus the letters, were rotate...

In grade school, students learn a standard set of Euclidean triangles. Among this set, the usual 45–45–90 and 30–60–90 triangles are the only right triangles with rational angles and side lengths each containing at most one square root. Are there any other such right triangles? We answer this question completely and present an elegant complement called Ailles’ rectangle that deserves to be in e...

As cases of the novel coronavirus disease (COVID-19) continue to rise, so are concerns effects this pandemic could have on people living with HIV. In response pandemic, measures been put in place by African governments limit spread virus.

No evidence of previous local or total body irradiation, transplantation, iatrogenic immunosuppression, blood transfusion, tuberculosis, or acquired immunodeficiency syndrome was found in the patient’s medical history. She had undergone extraction of her right maxil...

the right ventricle (rv) is a complex structure with abstruse function that reveals important differences when compared to the left ventricle (lv), so it cannot be described as a simple geometric form and achromatic physiology. as an inference from this fact, in the present review, we aim to describe rv structure including the embryology, anatomy, and physiology and present a functional, hemody...
