BACKGROUND Muslim women tend to postpone their menstrual period using short course oral contraceptives (OC) during Ramadan, Muslims fasting month. Recently, many cases of stroke, particularly cerebral vein thrombosis (CVT), have been reported in Ramadan. OBJECTIVE This work studies the incidence of CVT and its relation to Ramadan. MATERIALS AND METHODS This is a cohort study conducted from ...

SAR images are used in many applications which highlight the monostatic configuration limitations. Thus, we study in this paper a new imaging scheme : the bistatic configuration which seems to overcome some of the monostatic limitations. In order to validate the interest of this particular geometrical configuration, we developed a bistatic SAR simulator and validated the obtained results by exp...

We present herein a topological invariant of oriented alternating knots and links that predicts the three-dimensional (3D) writhe of the ideal geometrical configuration of the considered knot/link. The fact that we can correlate a geometrical property of a given configuration with a topological invariant supports the notion that the ideal configuration contains important information about knots...

“Telehealth” is a delivery of health-related services and information via telecommunications technologies. Clinical video telehealth (CVT) is a form of telehealth using a real-time video and audio transmission that is used to virtually connect a health care professional and a patient. CVT links the patient at a clinic closer to his or her home to a provider at another location. The goal of tele...
