Failed dwarf galaxy survives galactic collision thanks to full dark-matter jacket
Failed dwarf galaxy survives galactic collision thanks full dark-matter jacket
2014/6/19
Like a bullet wrapped in a full metal jacket, a high-velocity hydrogen cloud hurtling toward the Milky Way appears to be encased in a shell of dark matter, according to a new analysis of data from the...

An inevitable consequence of the development of the offshore petroleum industry is the eventual obsolescence of large offshore structures. Proper methods for removal of decommissioned offshore platfor...
柴油机缸盖水腔流动与沸腾传热的流固耦合数值模拟（Fluid-solid Coupling Numerical Simulation on Flow and Boiling Heat Transfer of Cooling Water-jacket in Cylinder Head of Diesel Engine）
气缸盖 冷却水腔 沸腾传热 流固耦合 数值模拟
2010/5/5
采用CFD软件STAR-CD和FEA软件ABAQUS对226B型柴油机缸盖冷却水腔内的流动和传热过程进行了流固耦合数值模拟计算。为反映沸腾传热的影响，基于FORTRAN语言开发了单相流沸腾传热模型，将其嵌入到STAR-CD中。与试验结果的比较表明，加入沸腾传热模型可以大幅度提高模拟计算的精度，最大误差由18%下降至7%，为柴油机冷却水腔的优化设计提供了理论依据。 Fluid-solid coupl...
An evaluation of buoyancy jacket safety in 1,000 diving incidents
DIVING Equipment BUOYANCY Buoyancy compensation buoyancy compensating device fatality equipment failure jacket accident Incident maintenance
2009/5/26
There were 154 incidents involving buoyancy jacket
use, misuse and malfunction in the first 1,000 incidents
reported to the Diving Incident Monitoring Study (DIMS).
Forty eight of these incidents i...
The time came when I humbled Warden Atherton to unconditional surrender, making a vain and empty mouthing of his ultimatum, "Dynamite or curtains." He gave me up as one who could not be killed in a st...
Next to Oppenheimer and Morrell, who rotted with me through the years of darkness, I was considered the most dangerous prisoner in San Quentin. On the other hand I was considered the toughest-- toughe...
Suspended animation is nothing new, not alone in the vegetable world and in the lower forms of animal life, but in the highly evolved, complex organism of man himself. A cataleptic trance is a catalep...
You, my reader, will remember, far back at the beginning of this narrative, how, when a little lad on the Minnesota farm, I looked at the photographs of the Holy Land and recognized places and pointed...
Warden Atherton, when he thinks of me, must feel anything but pride. I have taught him what spirit is, humbled him with my own spirit that rose invulnerable, triumphant, above all his tortures. I sit ...
When, at the conclusion of my first ten days' term in the jacket, I was brought back to consciousness by Doctor Jackson's thumb pressing open an eyelid, I opened both eyes and smiled up into the face ...
Long before daylight the camp at Nephi was astir. The cattle were driven out to water and pasture. While the men unchained the wheels and drew the wagons apart and clear for yoking in, the women cooke...
Now that I had learned the trick the way was easy. And I knew the way was bound to become easier the more I travelled it. Once establish a line of least resistance, every succeeding journey along it w...
The door clanged, shutting out all but a little light, and I was left alone on my back. By the tricks I had long since learned in the jacket, I managed to writhe myself across the floor an inch at a t...
And above all things, next morning Warden Atherton came into my cell on murder intent. With him were Captain Jamie, Doctor Jackson, Pie- Face Jones, and Al Hutchins. Al Hutchins was serving a forty-ye...
One thing of great value I learned in the long, pain-weary hours of waking--namely, the mastery of the body by the mind. I learned to suffer passively, as, undoubtedly, all men have learned who have p...
