Electrochemical machining (ECM) represents an essential processing method for deep and narrow grooves in metals. By applying electrochemical principles to calculate modify the cathode, L-shaped design was developed control electrode distance by replicating optimizing sidewall taper of a molded aiming minimize its impact. A physical simulation model analyze stress distribution, flow velocity influence current density on cathodes with varying tapers. Experiments were conducted system...
The low efficiency of somatic cell nuclear transfer (SCNT) greatly limits its application. Compared with the fertilized embryo, cloned embryos display abnormal epigenetic modification and other inferior developmental properties. In this study, small RNAs were isolated, miR-34c miR-125b quantified by real-time PCR; results showed that these micro-RNAs highly expressed in sperm. test sample was divided into three groups: one group, SCNT control group (NT-C group), third consisted injected...
Extracellular vesicles (EVs), as a promising platform for drug delivery, have attracted much attention. Degradation and regeneration of EVs maintain their homeostasis in vivo, but this is missing the vitro culture (IVC) system, which likely to lead negative effects. It particularly concerning that most studies involving addition IVC seem overlook point.We used rabbit embryos oviduct fluid model embryo development examine effect loss or gain EV functionality an system. Embryonic ratios were...
Rocket kerosene plays an important role in the regenerative cooling process of rocket thrust chambers. Its thermal conductivity determines efficiency and tendency to coke engines. In this paper, graphene nanoplatelets (GNPs) were introduced into improve its conductivity. Molecular dynamics simulation was used investigate composite system underlying mechanism. Firstly, by studying effect mass fraction GNPs, it found that, when increases from 1.14% 6.49%, 4.26% 17.83%, which can be explained...
In this paper, the bubble nucleation process of water was studied by molecular dynamics (MD) simulation. The mechanism on a grooved substrate revealed from perspective hydrogen bond and energy change, effect system pressure studied. results show that molecules is essentially in which thermal motion gradually intensifies continues to break with increase kinetic energy. As breaks, continuously converted intermolecular potential By analyzing composition energy, it found electrostatic much...
This study explores the bubble nucleation process and heat transfer characteristics on nanostructured solid surfaces with mixed-wettable pillars using molecular dynamics simulations. Five different were designed by varying wettability of central while keeping lateral hydrophilic. The behavior argon bubbles was observed to differ significantly across these due combined effects nanostructuring mixed wettability. On hydrophilic pillars, nuclei primarily formed above minimal among them, owing...
Low-voltage DC power distribution system has obvious advantages in distributed supply grid connection, quality and dispatch management, which is an important way to transform the traditional low-carbon environment-friendly system. It become a research hotspot field of electric energy internet today. makes fault identification difficult problem due rapid development faults numerous sources. In this paper, we propose longitudinal directional differential protection method based on variable...
At present, the electric power industry is developing rapidly. The installed capacity of each plant expanding, and short circuit current also growing traditional limiter not only difficult to break large current. Before breaking off may have caused damage equipment, causing huge economic losses. in order meet demand market our country, research development a new practical which can limit high fault imperative. Besides will bring benefits plants substations industry, it be used supply sets...
Abstract When a short-circuit fault occurs, it is important to avoid the problem of excessive current. This paper offers current limiter scheme which considers both flow capacity and limiting capacity. The feasibility verified by building simulation model power grid around 110/11 kV substation. In addition, optimal performance parameters each component are determined.
