Student-level numerical simulation of conditions inside an exploding fission-bomb core

Natural Science 2010年第3期2卷 139-144页

作者： bruce cameron reed 不详

This paper describes a freely-available spread-sheet that has been developed to simulate the conditions of reaction rate, core acceleration and velocity, energy generation, and pressure within a detonating fission-bomb core. When applied to a model of the Hiroshima Little Boy bomb, the spreadsheet predicts a yield of 12.7 kilotons, a figure in reasonable agreement with published values.

A desktop-computer simulation for exploring the fission barrier

引用

Natural Science 2011年第4期3卷 323-327页

作者： B. cameron reed 不详

A model of a fissioning nucleus that splits symmetrically both axially and equatorially is used to show how one can predict the presence of a fission barrier of several tens of MeV for nuclides of mass number A ~ 90 and of ~ 10 MeV for elements such as uranium. While the present model sacrifices some physical realism for the sake of analytic and programming simplicity, it does reproduce the general behavior of the run of fission barrier energy as a function of mass number as revealed by much more sophisticated models. Its intuitive appeal and tractability make it appropriate for presentation in a student-level “Modern Physics” class.

Aberrant Right Ovarian Artery from Proximal Internal Iliac Artery in Uterine Artery Embolization Patient

引用

Open Journal of Radiology 2012年第4期2卷 117-119页

作者： Richard A. reed bruce McLucas Department of Obstetrics and Gynecology David Geffen School of Medicine at the University of California Los Angeles USA Department of Radiology Huntington Memorial Hospital Pasadena USA

Some patients who undergo Uterine Artery Embolization (UAE) for symptomatic leiomyomata have collateral ovarian artery supply to the uterus. This typically occurs when the ipsilateral uterine artery is small or absent, and the ovarian artery supply to the uterus can lead to UAE failure. The authors present a case of a woman treated with UAE who had an atretic right uterine artery and an enlarged right ovarian artery supplying the fibroids. The ovarian artery arose from the proximal internal iliac artery. This rare variant vessel was embolized leading to eradication of the patient’s symptoms. The success of this case highlights the need to evaluate for possible variant ovarian artery supply and to embolize these vessels in an attempt to prevent UAE failure.

疯狂英语（阅读版） 2009年第8期 50-53页

作者： W. bruce cameron 远行的心

念中学时，我很怕我女友的父亲。我相信他总怀疑我要对他女儿毛手毛脚。他会打开门，立马露出一副“笑里藏刀”的表情，伸出手来和我握手，而当我的手被他握住时，感觉那股力量能把碳压炼成钻石。

"无焰"氧—燃料燃烧是一项成形技术,已在钢包预热和加热炉上应用。在应用过程中发现,该项技术可以节省约50%的燃料,同时也可以减少CO2排放。将部分无焰氧—燃料燃烧原理应用到高炉热风炉是一种新的尝试。与传统燃烧方式相比,该技术可使操作成本大幅降低,这是源于其有效的废热回收,以及采用"热"的富氧烟气循环来替代"冷"空气。由于用二氧化碳替代了不辐射的氮分子,增强了炉内的热量传递。氧—燃料燃烧概念的一个重要推论就是烟道烟气中CO2的体积分数大约可提升40%~50%,且质量流量变为原来的两倍。该项技术容易实现低成本碳捕获,而且如果实现碳封存,那么就有可能减少整个炼钢流程中大约30%的碳足迹。
