| 1 | A study of fire propagation in coal seam with numerical simulation of heat transfer and chemical reaction rate in mining field显示文摘Spontaneous combustion of coal is a problem that affects the mining operation and generates environ-mental,economic,social and geotechnical impacts.This phenomenon has been divided into two pro-cesses:ignition and propagation.Fire propagation develops in coal seams because of a set of factors such as direction and wind speed,fracturing and temperature.In this work,heat transfer and chemical kinetics are studied from conservation equations of energy and species,respectively,using the software COMSOL Multiphysics to simulate the propagation of fires in coal seams.Two possible scenarios were analyzed that usually occur in the walls of the coal seams,such as fire focus and fire complete screens.It was found that the propagation kinetics of the fire changes depending on the temperature,the fractur-ing of rock mass and the area of fire influence.For temperature values lower than 300℃,there is con-sumption around 250 cm^3/h,values around 700℃,the consumption is 1500 cm^3/h,and for fires of 1200℃ have values of 3000 cm^3/h.Depending on the speed of propagation can vary from 4 to 17cm/day,considering on the level and fracturing of the final wall of the open pit. | Moisés Oswaldo Bustamante Rúa Alan José Daza Aragón Pablo Bustamante Baena | 2019 | International Journal of Mining Science and Technology2019，29，6： | 8 |
| 2 | Surface chemistry of carbon nanoparticles functionally select their uptake in various stages of cancer cells显示文摘表面的关系有他们和生物实体的相互作用的 nanoparticles 的物理化学的特征可以为 nanomedicinal 申请提供批评信息。这里,我们报导介绍的 sub-50 nm 碳 nanoparticles (CNP ) 的系统的合成中立, anionic,和 cationic 表面功能。有 10, 20,和 40 nm 水动力学缩放的 ~ 的 CNP 的一个子集与中立表面 headgroups 被综合。第一次,这些 CNP 的细胞的成为主观系统地在乳癌房间的各种各样的阶段被确定(早、迟了、变形) ,从而提供对充电和尺寸的一个参量的评价完成。当这些系统在各种各样的阶段与癌症房间交往了时,不同活动被观察。我们的结果显示变形乳癌能被介绍 anionic 磷酸盐组的 nanosystem 指向。为在癌症的迟了的舞台的病人,相反,药能与 sulfonate functionalized 碳 nanoparticles 被交付,它有细胞内部的运输的更高的概率。这研究将便于 nanoparticle 生物的实体相互作用的更好的理解,并且有 pathophysiology 的这知识的集成将与在癌的房间内为药交货穿过 endocytic 障碍的优异可能性的支持 nanomedicine 的工程。 | Indrajit Srivastava Santosh K.
