Lysosomal membrane damage suggests that it would be the major contributing factor of myocardial infarction followed by necrosis. The present investigation was carried out on the defensive effect of ethanolic extract of Rosa damascena Mill. L. extract on alterations in myocardial lysosomal enzyme activity and membrane bound Na+/K+ ATPases against isoproterenol induced myocardial infarction in rats...
Most of the organizations today generate and share textual descriptions of their products, services, and actions. Such textual collections consists of significant amount of structured information, which remains buried in the unstructured text. Even though information extraction algorithms provides the extraction of structured relations, they are often expensive and inaccurate. We present an alternative...
This paper presents the analysis of a renewal input multiple working vacations queue with balking, reneging and heterogeneous servers. Whenever the system becomes empty the second server leaves for a working vacation whereas the first server remains idle in the system. During a working vacation the second server provides service at a slower rate rather than completely stopping service. The steady-state...
This paper investigates a discrete-time single server finite buffer queue with single working vacation wherein the customers decide either to join the queue or balk. The inter-arrival times, service times and vacation times are assumed to be independent and geometrically distributed. Using matrix method, the steady-state probabilities are obtained. Various performance measures of the model and average...
This paper analyzes a finite buffer single server queueing system with multiple working vacations in which customers balk (i.e., refuse to join the queue). The inter-arrival times and service times during regular busy period are, respectively, arbitrarily and exponentially distributed. Vacation times and service times during vacation are exponentially distributed. Using embedded Markov chain and supplementary...
This paper analyzes a finite buffer renewal input queueing system with state-dependent services and state-dependent multiple working vacations. Service times during a service period and service times during a vacation period are exponentially distributed with state-dependent rates. We provide a recursive algorithm using the supplementary variable technique and treating the remaining inter-arrival...
