Convergent/divergent channels have real-world applications including the production of fibers and glass, fabrication plastic sheets, manipulation molten metal streams, industrial casting metal. This article intends to discuss flow thermal transport mixture nanoparticles, namely, copper molybdenum oxide in a base fluid (water) over wedge-shaped channel. The dissipation effects are taken into acc...

Sudden releases of pressurised hydrogen may spontaneously ignite by the so-called “diffusion ignition” mechanism. Several experimental and numerical studies have been performed on spontaneous ignition for compressed at ambient temperature. However, there is no knowledge phenomenon cryogenic temperatures. The study aims to close this gap performing experiments using a computational fluid dynamic...

The repertoire of Kv1 potassium channels expressed in presynaptic terminals of mammalian central neurons is shaped by intrinsic trafficking signals that determine surface-expression efficiencies of homomeric and heteromeric Kv1 channel complexes. Here, we show that a determinant controlling surface expression of Kv1 channels is localized to the highly conserved pore region. Point-mutation analy...

We consider a diamond-shaped dual-hop communication system consisting a source, two parallel half-duplex relays and a destination. In a single antenna configuration, it has been previously shown that a two-phase node-scheduling algorithm, along with the decode and forward strategy can achieve the capacity of the diamond channel for a certain symmetric channel gains [1]. In this paper, we obtain...

This study presents an experimental and numerical investigation on the use of high-resolution injection techniques to deliver sample plugs within a capillary electrophoresis (CE) microchip. The CE microfluidic device was integrated into a U-shaped injection system and an expansion chamber located at the inlet of the separation channel, which can miniize the sample leakage effect and deliver a h...

This paper aims to simulate an immiscible two-phase flow in two-dimensional T-shaped, modified cross-shaped, and cross-shaped micromixers numerically. The effects of various parameters, including Capillary number, phase rate ratio, channel width on the generation droplets were studied. Also, modification T-shaped was proposed. results reveal that equidistant tiny are generated compared ordinary...

The expression patterns of plasma membrane transporters that specify the epithelial cell type are acquired with ontogeny. To study this process during metanephrogenic mesenchyme-to-epithelium transition, branching ureteric buds with their adjacent mesenchymal blastema (mouse embryonic day E14) were dissected and explanted on a collagen matrix. In culture, induced mesenchymal cells condensed, ag...

  This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...

The microchannel heat sink has been recognized as an excellent solution in high-density flux devices for its high efficiency removal with limited spaces; however, the most effective structure of microchannels dissipation is still unknown. In this study, fluid flow and transfer high-temperature wavy various shaped fins, including bare channel, channel circular, square, diamond-shaped are numeric...

In this paper, we study a new problem of finding a convex drawing of graphs with a non-convex boundary. It is proved that every triconnected plane graph whose boundary is fixed with a star-shaped polygon admits a drawing in which every inner facial cycle is drawn as a convex polygon. Such a drawing, called an inner-convex drawing, can be obtained in linear time.
