Nanofluids are two-phase mixtures consisting of small percentages of nanoparticles (sub 1-10 %vol) inside a carrier fluid. The typical size of nanoparticles is less than 100 nm. These fluids have been exhibiting experimentally a significant increase of thermal performance compared to the corresponding carrier fluids, which cannot be explained using the classical thermodynamic theory. This study...

Although for many years insects were believed to be insensitive to curare (Harlow, 1958; Hopf, 1952; Krupp, Lendle & Stapenhorst, 1952; Roeder, 1948, 1953; Roeder & Weiant, 1950; Usherwood, 1963), the recent report of Larsen, Miller & Yamamoto (1966) has demonstrated that insects are, indeed, sensitive to curare. Subsequent investigations (McCann, 1966; Flattum, Friedman & Larsen, 1967; Friedma...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...

We present a computational investigation into the line shapes of peaks in conductance histograms, finding that they possess high information content. In particular, the histogram peak associated with conduction through a single molecule elucidates the electron transport mechanism and is generally well-described by beta distributions. A statistical analysis of the peak corresponding to conductio...

We investigated the bipolar resistive switching characteristics of the resistive random access memory (RRAM) device with amorphous carbon layer. Applying a forming voltage, the amorphous carbon layer was carbonized to form a conjugation double bond conductive filament. We proposed a hydrogen redox model to clarify the resistive switch mechanism of high/low resistance states (HRS/LRS) in carbon ...

introduction: vestibular evoked myogenic potential (vemp) has recently been broadly studied in vestibular disorders. as it is evoked by loud sound stimulation, even mild conductive hearing loss may affect vemp results. bone-conducted (bc) stimulus is an alternative stimulation for evoking this response. this study aims to assess the characteristics of bc-vemp in different groups of patients.   ...

Sebacic acid-based thixotropic supramolecular Ni( ii )/Zn( )-metallogels are utilized for inhibiting poisonous bacteria and offering light-responsive semiconducting diodes with non-ohmic conduction mechanism.

Asynchrony of conduction may prove to be an important mechanism for reentrant arrhythmias. The purpose of these experiments was to explore asynchronous conduction in the distal branches of the canine Purkinje system. Microelectrodes were placed in Purkinje bundle preparations resembling a T configuration, thereby permitting assessment of differential conduction times induced by premature beats ...
