let $g$ be a finite group‎. ‎we denote by $psi(g)$ the integer $sum_{gin g}o(g)$‎, ‎where $o(g)$ denotes the order of $g in g$‎. ‎here we show that‎ ‎$psi(a_5)< psi(g)$ for every non-simple group $g$ of order $60$‎, ‎where $a_5$ is the alternating group of degree $5$‎. ‎also we prove that $psi(psl(2,7))

BACKGROUND Regional cerebral oxygen saturation (rSO2) as assessed by near infrared frontal cerebral spectroscopy decreases in circulatory arrest and increases with high-quality cardiopulmonary resuscitation. We hypothesized that higher rSO2 during cardiopulmonary resuscitation and after return of spontaneous circulation (ROSC) would predict survival to discharge and neurological recovery. MET...

OBJECTIVES To evaluate the use of extracorporeal membrane oxygenation in prolonged cardiopulmonary resuscitation and to estimate how long cardiopulmonary resuscitation can be extended with acceptable results. DESIGN Review of consecutive adult in-hospital cardiopulmonary resuscitation patients without return of spontaneous circulation in 10 mins and with extracorporeal membrane oxygenation re...

cardiac magnetic resonance imaging (cmri) is a well-established noninvasive imaging modality in clinical cardiology. its ability to provide tissue characterization make it well suited for the study of patients with cardiac diseases. we describe a multi-modality imaging evaluation of a 45-year-old man who experienced a near drowning event during swimming. we underline the unique capability of ti...

conclusions the survival rate after in-hospital cpr was very low. the duration of cpr and the time of initiating cpr effects patients’ outcomes. these findings highlight the crucial role of an organized, skilled, well-established and timely cpr team. background despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (cpr). o...

further to our recently published findings, we have completed the analysis of our second year of prehospital data collection for the same service. we wish to expedite the availability of this data to clinicians, researchers and policy makers in the region. our 2015/2016 out-of-hospital cardiac arrest (ohca) data displayed the following demographic results: 514 ohca resuscitation attempts were a...

Background Effective basic newborn resuscitation is an important strategy to reduce the incidence of birth asphyxia and associated newborn morbidity and mortality. There is presently no valid and reliable tool to evaluate clinical midwives confidence to apply required s...

For finite groups, we investigate both converse Lagrange theorem (CLT) orders and supersolvable (SS) orders, and see that the latter form a proper subset of the former. We focus on the difference between these two sets of orders, reformulate the work of earlier authors algorithmically, and construct a computer program to enumerate such NSS-CLT orders. We establish several results relating to NS...
