We present all-electrical operation of a ${\mathrm{Fe}}_{x}{\mathrm{Cr}}_{1\ensuremath{-}x}$-based Curie switch at room temperature. More specifically, we study the current-induced thermally driven transition from ferromagnetic to antiferromagnetic Ruderman-Kittel-Kasuya-Yosida (RKKY) indirect coupling in ${\mathrm{Fe}/\mathrm{Cr}/\mathrm{Fe}}_{17.5}{\mathrm{Cr}}_{82.5}/\mathrm{Cr}/\mathrm{Fe}$...

OBJECTIVES We aimed to identify who sustains needlestick and sharps injuries, under what circumstances and what actions are taken to minimize the risk and in response to intraoperative NSSIs. METHODS The cross-sectional study was conducted in 2013 on 215 operation room personnel in 14 hospitals of the Hormozgan province, Iran. RESULTS Two hundred and fifty appropriate responders completed t...

STUDY OBJECTIVE To determine whether playing music or blocking noise can reduce bispectral index (BIS) values during propofol sedation. DESIGN Prospective, randomized, single-blinded study. SETTING Operating room. PATIENTS 63 ASA physical status I and II patients, aged 55 to 75 years, undergoing total knee replacement. INTERVENTIONS Patients were divided into three groups: noise, silenc...

the effect of clonidine, a central alpha2-adrenoreceptor agonist on reduction of anxiety, producing sedation and attenuation hemodynamic changes, were assessed during thissemi-experimental study in one of the hospitals of iran medical sciences university in tehran, 1994.   fifty surgical patients of either sex, 18-60 years of age, with asa physical status i or ii, gave informed consent to enter...

appendicitis is the most common surgical emergency with the incidence rate of 6-10%. although several studies have compared the two approaches of open (oa) and laparoscopic appendectomy (la) the technique of choice is still a matter of controversy. considering this background we designed a study to compare oa and la outcomes in our center. one hundred patients were included in this study perfor...

To realize high-temperature operation of Si qubits, deep impurity levels with large confinement energy, which are hardly thermally excited, have been introduced into wafers. Group II Zn and group VI impurities S Se, known to form levels, were the substrates by ion implantation. These samples analyzed for concentration-depth profiles, energy level depths, absence defects. introduce thin channels...
