The topic of how to improve the utilization of charge of have been drawing great attention from researchers and designer in this filed. In present paper,in order to investigate the influence of charge initiation manners on the scattering characteristics of semi-preformed fragment warhead, the numerical simulations and experimental test are conducted.Firstly, the influence of grid density on numerical results is investigated, and a proper numerical model with relatively high accuracy and effectiveness is determined. Then. numerical simulations of three kinds of different initiation position of a semi-preformed fragment warhead are carried out. An experimental test of the explosion of a semi-preformed fragment warhead is carried out. By comparing and analyzing the numerical results and experimental data, it is found that the initiation manners have great influence on scattering characteristics of semi-preformed fragment warhead. The researcher work of this paper would provide an effective alternative method to optimize the design of warhead.展开更多

It is important and necessary for people to know the differences between Chinese and western table tanners, which can help to have a better understanding of the dietary culture in two cultures. Learning and applying table manners correctly can not only help to prevent gaffe, but also develop the ability of cross-culture communication and avoid cultural conflicts.展开更多

We surveyed the incidence of all deaths that occurred from 2018 through 2021 which came through the Marion County Coroner’s Office, Indiana. The data was then divided into two halves. According to the data, the leading manner of death in the first half and second half was accidental. This study revealed a total of 8732 cases: 3817 of them were observed to be accidental, 3092 natural, 956 homicide, 689 suicide, and 178 were undetermined. There were initially 318 drug overdose related deaths in 2018 and they increased to 2163 by 2021. In 2018, the number of deaths due to fentanyl related overdoses increased from 195 to 799 in 2021. This research will contribute to the forensic science field by providing information about the manner of death and fentanyl trends in Marion County over the last four years.展开更多
