The tubular ascidian heart is composed of a single layer of cells joined together by apical (zonulae occludentes) and spot (maculae occludentes) nexuses. Intercalated discs or desmosomes were not observed in this tissue. Rectangular pulses of current were applied across the opened and flattened myocardium. Assuming that all the transepithelial current flowed through a uniform gap between cells,...

Abstract Cubadak area was located in depression zone of great Sumatra fault which affected by normal faults. Geothermal this characterized the appearance hot springs type chloride-bicarbonate on Cubadak, Sawah Mudik and Talu. The manifestation temperature is about 37,1° - 74,8° C. This study purpose to recontruct model subsurface geothermal system based MT data. Model 1-D processed apply Bostic...

Abstract Seismic inversion is a geophysical technique used to estimate subsurface rock properties from seismic reflection data. data has band-limited nature and contains generally 10–80 Hz frequency hence combines well log information along with extract high-resolution acoustic impedance which low as high frequencies. This property qualitative quantitative of that can be analyzed enhance geolog...

This paper introduces a concept that allows the creation of low-resistance composites using a network of compliant conductive aggregate units, connected through contact, embedded within the composite. Due to the straight-forward fabrication method of the aggregate, conductive composites can be created in nearly arbitrary shapes and sizes, with a lower bound near the length scale of the conducti...

3 Ordered Cu-(35–50) at.% Pd alloys (B2-type superstructure) have a high corrosion resistance and are distinguished by possessing very low electrical resistivity r » (4–8) × 10 ohm m (1), two properties which make them of interest to researchers developing functional materials. However, wide-scale use of these alloys is hindered by their relatively poor strength properties: the yield stress of ...

The passive electrical properties of glycerol-treated muscle fibers, which have virtually no transverse tubules, were determined. Current was passed through one intracellular microelectrode and the time course and spatial distribution of the resulting potential displacement measured with another. The results were analyzed by using conventional cable equations. The membrane resistance of fibers ...

This paper reports the recent development and applications of conductive boron-doped ultrananocrystalline diamond (BD-UNCD). The authors have determined that BD-UNCD can be synthesized with an H-rich gaseous chemistry and a high CH4/H2 ratio, which is opposite to previously reported methods with Ar-rich or H-rich gas compositions but utilizing very low CH4/H2 ratios. The BD-UNCD reported here h...

the subsoil and groundwater were suspected to be polluted by leakage from underground tanks around the oil storage facility in Dhanbad, Jharkhand, India. to delineate the seepage zone, integrated geophysical methods comprising Ground Penetrating Radar (GPR) and 2D electrical Resistivity Imaging (eRI) methods were employed over the suspected zone and in the close vicinity. the studies were condu...

DOI: 10.17014/ijog.9.2. The phenomenon of land subsidence in Negeri Sila Nusalaut Island was caused by an earthquake Ambon and surrounding areas on September 26, 2019 with the magnitude 6.5. This research had been conducted using a resistivity method dipole-dipole configuration. Land occurred due to seawater intrusion around area. trigger, so soil creep occurred.The purpose this study is obtain...
