2011年4月22曰,就在安贝尔•莫里斯(Amber Morris)计划结婚前不久,她走进了圣路易斯的一家“好市多”超市。等待她的是一个水坑。莫里斯在店里滑倒了,右膝盖重重地摔在地板上,膝盖骨脱臼。未婚夫把她扶起来,拍了一张她摔倒的地板上沾满烤鸡油的照片。两周后,莫里斯接受了紧急手术,却再也没能走出手术室。心脏里的血块让她的生命永远定格在了39岁。她葬礼那天本应是她举行婚礼的日子。

我8岁的时候，很讨厌去主日学校。我宁愿待在家里。但每个星期日，妈妈都不停地催我起床，梳洗更衣，准备去主日学校。等我一切搞定，往往已经耽搁了不少时间。害得大家一路匆匆忙忙，几乎每次都要跑着进教堂才不至于迟到。

墨西哥圣金廷作为一个地理独立系统为整体分析物质流动和社会经济约束提供了理想场所。由于园艺作作(主要是西红柿)的种植,该地区陆地部分自然资源利用主要受地下水开采制约。灌溉用水量超过补给量减去输出量差值的6倍。牡蛎养殖主导着海湾内的资源利用。牡蛎的食物由潮汐时海湾水和海洋水交换而提供。牡蛎和整个系统的呼吸量表明,当前的水产养殖水平是可持续水平的40%。提出"物质不可持续能力指数"(PhUI)来衡量最大限制性资源利用远离可持续利用水平的比例:陆地由6,海湾内为0.4。在PhUI和测算经济发展的基础上,我们得出了水产养殖业比农业更可行的结论。

We present detailed characterization of laser-driven fusion and neutron production(-10^(5)/second) using 8 mJ, 40 fs laser pulses on a thin(vistic intensity(~ 5 × 10^(18)W/cm^(2))and high repetition rate(1 kHz), the system produces deuterium±deuterium(D-D) fusion, allowing for consistent neutron generation. Evidence of D-D fusion neutron production is verified by a measurement suite with three independent detection systems: an EJ-309 organic scintillator with pulse-shape discrimination, a ~3He proportional counter and a set of 36 bubble detectors. Time-of-flight analysis of the scintillator data shows the energy of the produced neutrons to be consistent with 2.45 Mev. Particle-in-cell simulations using the WarpX code support significant neutron production from D-D fusion events in the laser±target interaction region. This high-repetition-rate laser-driven neutron source could provide a low-cost, on-demand test bed for radiation hardening and imaging applications.
