edge detection and edge enhancement techniques play an essential role in interpreting potential field data. this paper describes the application of various edge detection techniques to gravity data in order to delineate the edges of subsurface structures. the edge detection methods comprise analytic signal, total horizontal derivative (thdr), theta angle, tilt angle, hyperbolic of tilt angle (h...

Freshwater input to estuaries may be greatly altered by the river barrages required to meet human needs for drinking water and irrigation and prevent salt water intrusion. Prior studies have examined the salt plugs associated with evaporation and salt outwelling from tidal salt flats in single-channel estuaries. In this work, we discovered a new type of salt plug formation in the multi-channel ...

Abstract Type-III secretion systems (T3SSs) of the bacterial flagellum and evolutionarily related injectisome are capable translocating proteins with a remarkable speed several thousand amino acids per second. Here, we investigate how T3SSs able to transport at such high rate while preventing leakage small molecules. Our mutational evolutionary analyses demonstrate that an ensemble conserved me...

This study presents a comparison of forcings between density gradient and tides in idealized funnel-shaped salt-plug estuaries. Three-dimensional numerical model results also examine longitudinal lateral circulations. In estuaries, positive estuarine circulation is observed landward salinity maximum zone or salt plug. Seaward the plug, estuary shows an inverse cell. The flows show fortnightly v...

In the Molten Salt Reactor, freeze plug is one of components that plays an important role when a reactor accident occurs. designing plug, selection constituent material based on ability to spread heat. Therefore, studies are needed provide information regarding design. The modified melting process has been simulated using Moving Particle Semi-Implicit method. This study aims observe behavior ph...

This study employs Multi-Layer Perceptron (MLP) to estimate environmental impact of salt plugs using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). VNIR and SWIR datasets of ASTER were assessed in mapping and detecting Jahani, Konarsiah, and Kohe Gach salt plugs and the affected areas located at SE Shiraz, Iran. PC color composite and geological map of the region were u...

We describe here an improved method for isolating, purifying, and cloning DNA from diverse soil microbiota. Soil microorganisms were extracted from soils and embedded and lysed within an agarose plug. Nucleases that copurified with the metagenomic DNA were removed by incubating plugs with a high-salt and -formamide solution. This method was used to construct large-insert soil metagenomic librar...

Novel fabrication techniques and polymer systems are being explored to enable mass production of low cost microfluidic devices. In this contribution we discuss a new fabrication scheme for making microfluidic devices containing porous polymer components in situ. Contact lithography, a living radical photopolymer (LRPP) system and salt leaching were used to fabricate multilayer microfluidic devi...

Ionic liquid based aqueous biphasic systems (IL-ABS) were formed by the addition in water of a hydrophilic ionic (1-Butyl-3-methylimidazolium Chloride, C4mimCl) and kosmotropic salt (tripotassium phosphate, K3PO4). The flow patterns IL-ABS studied capillary channels with 0.2, 0.5 0.8 mm internal diameter; this is first time such two-phase flows have been investigated. Three weight concentration...
