We report low-temperature measurements of the electrical transport properties of few-atom contacts of the superconducting metal zinc, arranged with lithographically fabricated mechanically controllable breakjunctions (MCB). The conductance histogram shows several narrow peaks, not regularly observed for multivalent metals. The first peak corresponding to the single-atom contact is located sligh...

background: pain is a common experience among mechanically ventilated patients. pain among mechanically ventilated patients is aggravated by factors such as stage of illness, invasive procedures, and surgical interventions. the aim to this study was to investigate pain levels and predictors among mechanically ventilated patients during rest and routine nursing interventions. materials and metho...

background: underlying diseases and aggressive procedures, such as different types of surgery and care, for patients with critical conditions in intensive care units (icu) may be associated with physiological disorders. objectives: this study intended to determine the effect of therapeutic touch on physiological variables of patients undergoing mechanical ventilation in icu. methods: this rando...

  Abstract   The effect of mechanical activation using an attrition mill on the particle size of an ilmenite concentrate and its effect on the ability of the concentrate for Iron separation during hydrochloric acid leaching and the kinetics of the dissolution process have been investigated. It was observed that mechanical activation in an attritor significantly enhances the dissolution of iron ...

background ventilator-associated pneumonia (vap) develops in mechanically ventilated patients 48 hours after putting the patients on the ventilator. vap is the second most common nosocomial infection in neonatal intensive care units (nicu). objectives the current study was conducted to determine the rate, microbiological characteristics and outcome of vap in neonates admitted in the nicu of sho...

We have developed a veriied application proved to be both eeective and eecient. The application generates moves in the puzzle-game Nim and is coded in Piton, a language with a formal semantics and a compiler veriied to preserve its semantics on the underlying machine. The Piton compiler is targeted to the FM9001, a recently fabricated veriied microprocessor. The Nim program correctness proof ma...
