a uterocutaneous fistula is a rare clinical presentation that occurs following cesarean section and other pelvic operations. there are only a few reports discussing the treatments. we describe a patient with successful surgical management and review the literature. a 25-year-old woman referred to our department 13 months after her first cesarean section. she had a history of an abdominal mass a...

Nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. This has resulted in unanticipated congestion interfaces in regional transmission systems. The system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. To make the m...

this paper presents a relatively new management model for the optimal design and operation of irrigation water pumping systems. the model makes use of the newly introduced particle swarm optimization algorithm. a two step optimization model is developed and solved with the particle swarm optimization method. the model first carries out an exhaustive enumeration search for all feasible sets of p...

The issue of unit commitment is one of the most important economic plans in power system. In modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. Hence power system operation confronts units’ participation and input considering network security constrains. The issue of units’ participation is ...

background: nursing project management is widely used in different aspects of the society. however, whether the nursing project management can control the infections in the operation room (or) is rarely reported. we evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the or infections. methods: overall, 382...

background: several reservoir systems have been constructed for hydropower generation around the world. hydropower offers an economical source of electricity with reduce carbon emissions. therefore, it is such a clean and renewable source of energy. reservoirs that generate hydropower are typically operated with the goal of maximizing energy revenue. yet, reservoir systems are inefficiently ope...

For most beef cow herds, the single most important means of increasing income is increasing the number of calves weaned and sold, relative to the number of cows in the operation, or by definition, increasing reproductive efficiency. While certain production and carcass traits can be most directly influenced by genetic selection, reproductive performance is overwhelmingly influenced by managemen...

The focus of this paper is ontology-based knowledge management in the framework of a mobile communication and information system for rescue operation management. We present a novel ontology data service, combining prior domain knowledge about large-scale rescue operations with dynamic information about a developing operation. We also discuss the integration of such a data service into a service...
