Interactions between peripheral conduction system and myocardial wave fronts control the ventricular endocardial activation sequence. To assess those interactions during sinus and paced ventricular beats, we recorded unipolar electrograms from 528 electrodes spaced 0.5 mm apart and placed over most of the perfused rabbit right ventricular free wall endocardium. Left ventricular contributions to...

The article deals with the problems of buildings built many years ago, in which current and major repairs were not carried out an appropriate manner. At same time, experience various deformations, such as yield, heel, subsidence, deflections, bends, twists, distortions, horizontal displacements. survey residential 80s is described analysis results one these out. theoretical problem distribution...

The topography of somatosensory evoked magnetic fields (SEFs) following stimulation of the upper and lower lips was investigated in 6 normal subjects. When the lateral side of the upper lip was stimulated, P20m and its counterpart, N20m, were identified in the hemisphere contralateral to the stimulated side. The equivalent current dipoles (ECDs) of N20m-P20m were considered to be located in lip...

The research and analysis of technical conditions, deflections, bearing capacity subjected to fire impact reinforced concrete slabs raised “panel per room” typical design model 1-480a a five-storey residential building in Lviv are present. A study the condition floor structures area high temperatures. In intense decrease rigidity shelf tent slab under action temperatures was found. Due impact, ...

this paper deals with the solution of a column with balcony loads. it is intended to determine the expressions for deflections and bending moments of the sections of a column under the action of transmitted loads from a balcony loaded at its free end by a force «p» and rigidly connected to the column somewhere between its ends. the action of this load on the column is equivalent to that of the ...

Trigeminal ganglion neurons in adult rats adapt to periodic whisker deflections in the range of 1-40 Hz, manifested as a reduction in spike counts to progressively later stimuli in a train of pulsatile or sinusoidal deflections. For high velocity, pulsatile deflections, adaptation is time- and frequency-dependent; as in the case of thalamic and cortical neurons, adaptation is greater at higher ...

Common quasi-static electrostatic micro actuators have significant limitations in deflection due to electrode separation and unstable drive regions. State-of-the-art electrostatic actuators achieve maximum deflections of approximately one third of the electrode separation. Large electrode separation and high driving voltages are normally required to achieve large actuator movements. Here we rep...

Surface stress is a material property that underpins many physical processes, such as the formation of self-assembled monolayers and the deposition of metal coatings. Due to its extreme sensitivity, atomic force microscopy ~AFM! has recently emerged as an important tool in the measurement of surface stress. Fundamental to this application is theoretical knowledge of the effects of surface stres...
