—A monolithic active pixel sensor operating in current mode for charged particle detection is described. The sensing element in each pixel is an n-well/p-sub diode with a PMOS transistor integrated in an n-well. The drop of the n-well potential from the collection of charge modulates the transistor channel current. Each pixel features two current mode(More)
CMOS pixel sensors are being developed for the CBM Micro-Vertex Detector (MVD). They provide the high resolution required to reconstruct efficiently decay vertices of short-lived particles , such as charmed mesons. The present R&D is mainly driven by the severe running conditions expected in the vicinity of the experimental target. The most significant(More)
We carried out a prospective study of 200 pregnant women who required induction of labor at full term, at the Lalla Meryem maternity unit of the Ibn Rochd University Hospital, Casablanca, between January 1st 1996 and June 30th 1997. The aim of this study was to evaluate the efficacy, tolerance and acceptance of misoprostol (Cytotec) as a drug for inducing(More)
Sciatic nerve endometriosis is rare but must be included in the sciatic pain aetiology diagnosis. Typically the patient's sciatic pain is cyclic. Electromyography and computed tomographic scanning or nuclear resonance imagery contribute to the diagnosis. Different mechanisms of this localization have been proposed. The patient often requires conservative(More)
We carried out a retrospective analysis of 3,231 cases of cesarean section between 1994 and 1997, to assess the maternal mortality and morbidity associated with this intervention. The frequency of cesarean delivery was 12.4%. The indications for cesarean section were of three types: elective indications (627 cases, 19.4%), emergency indications (454 cases,(More)
CMOS Monolithic Active Pixel Sensors (MAPS) are proposed as a technology for various vertex detectors in nuclear and particle physics. We discuss the mechanisms of ionizing radiation damage on MAPS hosting the the dead time free, so-called self bias pixel. Moreover, we discuss radiation hardened sensor designs which allow operating detectors after exposing(More)
