Simultaneous 4-Chamber Strain

Simultaneous 4-Chamber Strain

Analysis of myocardial deformation, or strain imaging, is becoming part of routine echocardiography. The most widely accepted parameter to date has been global longitudinal strain as a measure of global left ventricular (LV) function. Global longitudinal strain (LS) of the LV, in (negative) percent, is the average of the maximal shortening (in percent) in the apicobasal direction of each of 18 ...

Muscle chamber with strain gauge adapted for isotonic/isometric recording.

Simple devices are described that can facilitate student experiments on mechanical and electrical aspects of muscle contraction, for example, of isolated preparations such as frog gastrocnemius and sartorius muscles and gut. The system includes a general-purpose preparation bath that was previously described for electrophysiological observations with suction electrodes [D.M. Easton. Am.J. Physi...

Application of dual chamber microbial fuel cell with aeration cathode for bioelectricity generation and simultaneous industrial wastewater treatment

Background and Objective: Microbial fuel cell (MFC) is a new green technology that uses the catabolic ability of microorganisms to produce bioenergy while simultaneously removing organic matter and other wastewater contaminants. Electrode material is one of the factors affecting the performance of microbial fuel cells. The aim of this study was to investigate the performance of microbial fuel c...

Simultaneous Interpolation of 4 Spatial Dimensions

The Minimum Weighted Norm Interpolation (MWNI) algorithm (Liu and Sacchi, 2001) has been proposed as a method to reconstruct band-limited seismic data along 1, 2 and 3 spatial dimensions. In addition, tests showing the ability of the method to reconstruct data prior to amplitude versus angle wave equation migration were provided in Liu et. al (2003). The method incorporates bandwidth limitation...
