Detonation velocity is an important parameter for explosive, and it is crucial for many fields such as dynamic chemistry burn models, detonation propagation prediction, explosive performance estimation, and so on. Dual-channel detonation velocity measurement method and system are described. The CFBG sensors are pasted both on the surface and in the center of the explosive cylinder. The length o...

the aim of this study was to investigate the effect of three types of resistance training program on girls' physical fitness. 30 girls were divided into 3 groups: plyometric training with vascular occlusion (plo), plyometric training without vascular occlusion (pl) and power-resistance training (pr). training programs were conducted for six weeks. physical fitness tests were conducted befo...

G protein-coupled receptor (GPCR) is a huge family of about 1000~2000 members in the mammal, and it has indeed various functions. The gene numbers in families are not equally distributed but show significant bias, in which species specific family are dominant. For instance, odorant receptors occupy more than 50% of GPCRs in mammals. Many previous works suggested that the species specific famili...

Recent post explosive control avalanches and the lack of analytical methods for evaluating explosive control have motivated this study to better quantify the effects explosives on snow. Currently, there are insufficient tools for predicting the effects that explosives will have on snow avalanche release. While there is significant practitioner experience, that experience has (on occasion) not a...

The assessment of fragmentation through blasting and therefore subsequent crushing and grinding stages is important in order to control and optimize the mining operation. Prediction of the mean size of fragmented rock by the rock mass characteristics, the blasting geometry, the technical parameters and the explosive properties is an important challenge for the blasting engineers. Some of the ef...

Giant mass failures of oceanic shield volcanoes that generate tsunamis potentially represent a high-magnitude but low-frequency hazard, and it is actually difficult to infer the mechanisms and dynamics controlling them. Here we document tsunami deposits at high elevation (up to 132 m) on the north-western slopes of Tenerife, Canary Islands, as a new evidence of megatsunami generated by volcano ...

Realistic explosion effects can enhance the realism and immersion in virtual battlefield. The real-time explosion effects simulation of the explosion products and their interactions, such as explosive fireball, explosive smoke and explosive ash, will be exploded into two phases: explosions and fuel modeling. The explosions modeling describe the formation and spreading of the explosive fireball....

This paper provides a means of accurately simulating explosive autoregressive processes, and uses this method to analyse the distribution of the likelihood ratio test statistic for an explosive second order autoregressive process. Nielsen (2001) has shown that for the asymptotic distribution of the likelihood ratio unit root test statistic in a higher order autoregressive model, the assumption ...

Trace explosive test surfaces are often required for the evaluation of trace detection equipment to determine the equipment performance. Test surfaces of C-4, Detasheet, Semtex-H, TNT, and HMTD were prepared by transferring trace amount of explosive deposited on polytetrafluoroethylene (PTFE) transfer strips onto different surfaces (Kraft paper, hard plastic, woven fabric, and soft vinyl). The ...

The field of mechanobiology has witnessed an explosive growth over the past several years as interest has greatly increased in understanding how mechanical forces are transduced by cells and how cells migrate, adhere and generate traction. Actin, a highly abundant and anomalously conserved protein, plays a large role in forming the dynamic cytoskeleton that is so essential for cell form, motili...
