lipoid congenital adrenal hyperplasia (lipoid cah), a rare disorder of steroid biosynthesis, is the most severe form of cah. in this disorder the synthesis of glucocorticoids, mineralocorticoids and sex steroids is impaired which result in adrenal failure, severe salt wasting crisis and hyperpigmentation in phenotypical female infants irrespective of genetic sex. in this report, we presented a ...

This article describes a quality improvement initiative, implemented by a patient education workgroup within a tertiary Magnet® facility. The project focused on the association between inadequate care transitions in patients with heart failure and subsequent costly readmissions. The teach-back initiative was piloted with patients hospitalized with heart failure, because of this population's hig...

In nuclear facilities, the reading of sensors is very important in assessments system state. The existence an abnormal state could be caused by a failure sensor itself instead system. So, being unable to identify main cause “abnormal state” and take proper actions may end unnecessary shutdown for facility that have expensive economic consequences. That why, it extremely supervision control case...

This paper describes the XSAP safety analysis platform. XSAP provides several model-based safety analysis features for finiteand infinite-state synchronous transition systems. In particular, it supports library-based definition of fault modes, an automatic model extension facility, generation of safety analysis artifacts such as Dynamic Fault Trees and Failure Mode and Effects Analysis tables. ...

The aim of the present paper is to analyze probabilistically various performance measures of two redundant systems under Weibull failure and repair activities using semi-Markov processes and regenerative point technique. Two stochastic models comprise of one original and one duplicate units are developedwith the provision of a single repair facility and priority. All repairs and preventive main...

BACKGROUND Optimal waiting time before first use of vascular access is not known. METHODS Two practices-first cannulation time for fistulae and grafts, and blood flow rate-were examined as potential predictors of vascular access failure in the Dialysis Outcomes and Practice Patterns Study (DOPPS). Access failure (defined as time to first failure or first salvage intervention) was modelled usi...

This study is concerned with the performance modeling of a fault tolerant system consisting of operating units supported by a combination of warm and cold spares. The on-line as well as warm standby units are subject to failures and are send for the repair to a repair facility having single repairman which is prone to failure. If the failed unit is not detected, the system enters into an unsafe...

We study the problem of locating facilities on the nodes of a network to maximize the expected demand serviced. The edges of the input graph are subject to random failure due to a disruptive event. We consider a special type of failure correlation. The edge dependency model assumes that the failure of a more reliable edge implies the failure of all less reliable ones. Under this dependency mode...
