Through an industrial application, we were confronted with the planning of experiments where human intervention of a chemists is required to handle the starting and termination. This gives rise to a new type of scheduling problems, namely problems of finding schedules with time periods when the tasks can neither start nor finish. We consider in this paper the natural case of small periods where...

This multimethod, prospective study examined the nature of pathways between interparental hostility and withdrawal, parental emotional unavailability, and subsequent changes in children's internalizing and externalizing behaviors, and school adjustment difficulties over a 3-year period in a sample of 210 mothers, fathers, and 6-year-old children. The results of autoregressive structural equatio...

This paper considers scheduling problems where the processing of a set of jobs has been scheduled (i.e., planned) to minimize a classical cost objective, under the assumption that the jobs are all available at the start of the planning horizon. Before processing starts, however, the availability of a subset of the jobs is delayed. Therefore, the decision maker needs to adjust the existing sched...

Touch is a critical channel of communication used by mothers to communicate and interact with their infants and to contribute to their infants' socio-emotional development. The present study examined maternal touching in 41 mothers with and without depressive symptomatology. Mothers and their 4-month-old infants participated in the Still-Face (maternal emotional unavailability) and Separation (...

Middleware has become an integral part of many distributed applications offering effective integration and interoperability solutions. In some situations a problem may occur where the integration of distributed information applications may be affected by scheduled unavailability of one or more of these applications. The scheduled unavailability occurs due to several reasons including applicatio...

In real world scheduling applications, machines might not be available during certain time periods due to deterministic or stochastic causes. In this article, the machine scheduling with availability constraints for both deterministic and stochastic cases with different environments, constraints and performance measures will be discussed. The existing body of research work in the literature wil...

fifty six episodes of dka occurred in 33 patients during the period between 1998 -96. these patients were admitted and treated in bahrami children hospital, a tehran university teaching medical center. the most frequent clinical manifestations consisted of polyuria and polydipsia (66%), nausea and vomiting (64%), reduction in consciousness (53%), and kussmaul respiration (53.5%). 54.6% of dka e...

Timely administration of dopamine agonists is of the essence in Parkinson's disease. The perioperative period especially for abdominal surgeries under general anaesthesia poses a challenge to oral drug administration. Alternatives such as rotigotine patches and subcutaneous apomorphine administration have been described but unavailability restricts their use. Sublingual administration of tablet...
