normal 0 false false false en-us x-none ar-sa background: the aim of this study was to compare the postoperative pain scores and morphine requirements between spinal anesthesia (sa) with hyperbaric bupivacaine 0.5% and general anesthesia (ga) with 1 minimal alveolar concentration (mac )of isoflurane in 50% n2o and o2 after elective lower abdominal surgery. materials and methods: in this randomi...

background: there is evidence that electrocardiographic (ecg) changes occur during elective cesarean section in parturients. these changes, mostly in the form of st-segment depression, have been noted in either regional anesthesia or general anesthesia. we performed this study to compare hemodynamic variables and electrocardiographic changes suggestive of myocardial ischemia following administr...

High-frequency digital signal processors are increasingly suffering from electro-magnetic interference, due to its ever-increasing integration level and operation speed. The accurate prediction of its electro-magnetic effects require less effort to be spared in the design procedures to obtain better electro-magnetic compatibility and to avoid later modifications that are lengthy and expensive. ...

The effect of a sacrificial layer residue on a cantilever beam in the nano-electro-mechanical nonvolatile memory is investigated for the optimization of reliability characteristics. Different from previous research, pull in voltage model of nano-electro-mechanical nonvolatile memory used triangular residue layer which is considered by real wet etching process. Modified pull in voltage model was...

Different electro-optic polymer systems are analyzed with respect to their electro-optic activity, glass transition temperature (Tg) and photodefinable properties. The polymers tested are polysulfone (PS) and polycarbonate (PC). The electro-optic chromophore, tricyanovinylidenediphenylaminobenzene (TCVDPA),which was reported to have a highest photochemical stability [1] has been employed in the...
