This paper determined the size of the heat sink of auxiliary converter of HXD1C locomotive.The required cooling air volume was calculated through experience formula.Three-dimensional calculation model for duct cooling systems numerical simulation had been set up by here using CFD software FLUENT, which was used to solve the temperature distribution
This paper investigated English swear words used read more in a novel.This study was urgent to conduct because using swear words is a natural behavior in communication which is indicated by the employment of certain swear words to express emotion, to reduce frustrated feeling, and to show solidarity to others.Two research points to resolve were as
Abstract Allioideae includes economically important bulb crops such as garlic, onion, leeks, and some ornamental plants in Amaryllidaceae.Here, we reported the complete chloroplast genome (cpDNA) sequences of 17 species of Allioideae, five of Amaryllidoideae, and one of Agapanthoideae.These cpDNA sequences represent 80 protein-coding, 30 tRNA, and
In nature Citrus tristeza virus (CTV), genus Closterovirus, infects only the phloem cells of species of Citrus and related genera.Finding that the CTV T36 strain replicated in Nicotiana benthamiana (NB) protoplasts and produced normal tillman 750m virions allowed development of the first genetic system based on protoplast transfection with RNA tran
This paper puts forward a constructive heuristic algorithm called the method of inserting the minimum neighbor edge from outside to the center (IMNEFOTC) that can be applied to solve large-scale and ultra-large-scale travelling salesman problems.Through it and iphone 14 price chicago the randomized greedy heuristic algorithm (RGH) which greedy heur
