The CRCW PRAM under dynamic fail-stop (no restart) processor behavior is a fault-prone multiprocessor model for which it is possible to both guarantee reliability and preserve eeciency. To handle dynamic faults some redundancy is necessary in the form of many processors concurrently performing a common read or write task. In this paper we show how to(More)
Fifty patients with seborrhoeic dermatitis were treated with 2% ketoconazole cream (n = 24) or with 1% hydrocortisone cream (n = 26) for 4 weeks in a double-blind comparative study. These twice daily applications resulted in 87.2% symptomatic improvement for hydrocortisone vs. 81.6% for ketoconazole. The number of P. ovale yeasts was significantly reduced(More)

OBJECTIVES To investigate whether air pollution is a potential risk factor for airways obstruction. METHODS A prospective cohort study (11.3 +/- 2.9 years) that took place in two areas (Eordea where concentration of PM10 was high and Grevena, Greece). We used the MRC questionnaire, spirometry, and anterior rhinomanometry at both visits. RESULTS(More)
Concurrent computations should combine eeciency with reliability , where eeciency is usually associated with parallel and reliability with distributed computing. Such a desirable combination is not always possible, because of an intuitive trade-oo: eeciency requires removing redundancy from computations whereas reliability requires some redundancy. We(More)
Forty patients with gastro-oesophageal reflux disease and oesophagitis, documented by endoscopy (grades I to III by the Savary-Miller classification) were randomized to participate in a comparative double-blind trial to receive cisapride (10 mg q.d.s.) or ranitidine (150 mg b.d.) for an 8-week period. Upper gastrointestinal endoscopy was performed(More)
Twenty-one women (mean age, 35.3 years) with 2 to 4 episodes of vaginal candidosis in the last 6 months were included in the study to evaluate the efficacy and safety of itraconazole as short-term, as well as prophylactic, treatment of chronic candidosis. After clinical evaluation and laboratory confirmation of candidosis, 200 mg of itraconazole were given(More)
