First of all, according to Wuhan Iron and Steel Plant sales in Hunan Province and the relative position of the city, the transport costs are calculated from Wuhan Iron and Steel Plant to the demand point. We further analyze the necessity of establishing steel logistics distribution center, using the precise center of gravity to determine the actual location of the distribution center. After the establishment of distribution center, the total freight is reduced by 15.46 million yuan from Wuhan Iron and Steel Plant to each city in Hunan province via distribution center each year. The results of this paper can provide theoretical basis for the logistics node planning of related enterprises.展开更多

It also causes a lot of skin discomfort after the consumers carry out such projects. This study, which combines small molecule active peptides (RW3) and active collagens and imitates the photoelectric treatment through in vitro and in vivo experiment, finds that small molecule active peptides (RW3) and active collagens have different improvement effects on cell proliferation, migration, anti-UV damage, inhibition of ear swelling and inflammation in mice, repair of UV damage and skin damage caused by microneedles. .展开更多
