The imbalance of phase loads is a natural negative property low-voltage three-phase four-wire network due to uneven connection the phases and difference in individual consumer demand for electricity. nodes leads decrease quality electricity, overestimated technical losses current overloads one power lines. In paper, balancing performed using heuristic algorithm based on average hourly readings ...

statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...

the aim of this study was to evaluate the long-term outcome of treatment using kirschner wires and tensioning bands for tarsocrural luxation with malleolus fractures resulting from trauma in dogs. eight dogs with tarsocrural luxation due to malleolus fracture were selected. following intrathecal anesthesia, the malleolus bone was returned to its normal position using two kirschner wires and ten...

Two companion papers describe an internally consistent general power theory valid for instantaneous and average power for systems with any number of wires, under conditions of unbalance, distortion or dc components. Measuring apparent power and power factor under non-ideal conditions, even in typical three-phase four wire systems, needs the resistances of the wires, particularly the neutral wir...

Why do we grow up to have the traits we do? Most 20th century scientists answered this question by referring only to our genes and our environments. But recent discoveries in the emerging field of behavioral epigenetics have revealed factors at the interface between genes and environments that also play crucial roles in development. These factors affect how genes work; scientists now know that ...

The static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. Thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. To do so, the wires are austenitized at different temperatures and cooled in different rates. Then the wires are drawn and aged at a specific temperature and time. Before and after aging of each...
