a new hydroxylamine sensor has been fabricated by immobilizing oxadiazol denvative at the surface ol aglassy carbon electrode (gce) modified by multi-wall carbon nanotube (mivcnt). the adsorbed thin illms oroxadiazol derivative on the mwcnt modified gce show a pair of peaks with surface confined characierisnus.the oxadiazol derivative mwcni (omwcnt) modified gce shows highly catalytic activity ...

medical environments such as hospital waiting rooms can affect a client’s anxiety level as wellas psychological and physiological responses to his or her situation. the aim of this research was to evaluatethe use of environmental design, specifically the design which incorporates elements of nature, in clinics andhospitals to decrease anxiety, blood pressure and pulse rates of waiting clients. ...

Introduction: Electroporation is a practical technique used to transport the molecules across the cell membrane. The utilization of fluorescent molecules is the method widely used to evaluate the electropermeability of cell membrane as a result of pulse application. It is also possible to use mathematical methods to predict the changes caused in cell electropermeability as a result of the chang...

Due to the growing demand for higher bandwidth, employing optical devices instead of electronic devices in data transmission systems has attracted much attention in recent years. Optical switches, modulators and wavelength converters are a few examples of the required optical devices. CMOS compatible fabrication of these devices, leads to much more growing of this technology. Optical pulse comp...

In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Dispos...

A 76-yr-old man with unipolar ventricular pacemaker, previously implanted in the right ventricular apex, presented with syncopal attack and twitching of the right pectoralis muscle. He finally was diagnosed as having Twiddler's syndrome. The patient had a pulse rate of 36/min and cannon waves in the neck veins. Chest radiography showed a dislodged pacing lead completely wrapped around the pulse...

background several studies have been carried out to evaluate the effects of dialysis on o2 saturation. while the dialysis procedure may lead to hypoxia under different circumstances, there are few studies available on the effects of membrane type on o2 saturation in these patients. objectives this study was to appraise the effects of high and low flux membrane on pulse oxymetery in dialysis pat...
