  | The James M. DuPont Meteorite Collection - Measurements of the Vatican Meteorite Collection The porosity of meteorites, a fundamental characteristic of their fabric, is important to a number of interesting problems in meteoritics. A knowledge of porosity is essential to calibrate the penetration depth of high energy particles, whose tracks in meteorites tell us exposure histories. Porosity may be an indicator of the lithostatic pressures experienced by a Meteorite telling us how deep within an asteroid it was originally placed. Most recently, comparing the bulk density of meteorites to that of asteroids has been used, with some controversy, to infer bulk asteroidal composition; at the very least a knowledge of Meteorite porosity is essential to estimate

 | The Don't quit poem Scene from the movie "career opportunities" http://www.imdb.com/title/tt0101545/ .. Don't quit When things go wrong, as they sometimes will, When the road you're trudging seems all uphill, When the funds are low and the debts are high, And you want to smile, but you have to sigh, When care is pressing you down a bit, Rest, if you must, but do not quit Life is queer with its twists and turns, As every one of us sometimes learns, And many a failure turns about, When he might have won had he stuck it out; Don't give up though the pace seems slow-- You may succeed with another blow. Often the goal is nearer than, It seems to a faint and faltering man, Often the struggler has given up, When he might have captured the victor's cup, And he learned too late when the night slipped down, How close he was to the golden crown. Success is failure turned inside out-- The silver tint of the clouds of doubt, And you never can tell how close you are, It may be near when it seems so far, So stick to the fight when you're hardest hit-- It's when things seem worst that you must not quit

We will discuss the new porosity data and their error sources and present some applications of the data for Meteorite research. References: [1] Schmitt et al. (1994) LPS XXV, 1209-1210.

 | The James M. DuPont Meteorite Collection - the classical water immersion technique [6,7]. In this comparison we have used various geological rock samples (in addition to meteorites) with variable porosity, mass, and shape. The water immersion measurements were carried out in the GSF laboratory by soaking the samples in tap water for 2-5 days and then drying the samples in an oven (%3C=105 degrees C) for a few days. The pore volume is calculated from the mass difference between water-saturated and dried samples, and the sample volume is determined by weighing the surface-dried wet sample in air and water (Archimedes' principle). Comparison of the two datasets reveal that there is an overall agreement with porosity over a wide range of values from 0.5% to 30%. However, the porosity values do not plot exactly

 | The James M. DuPont Meteorite Collection - pressure and temperature of the reference chamber filled with He (Pr, Tr) are measured, after which He is allowed to expand to the sample chamber, and the resulting Ps and Ts are recorded and time-monitored to obtain stationary readings. Knowing the geometric volume of the sample and the residual pressure of the chambers before they are filled with He, the porosity (epsilon) of the sample can be calculated using ideal gas equations [7]. The system is calibrated with standard aluminum disks. The advantages of this method are that measurements are relatively fast, and the often rare and fragile Meteorite samples are not disturbed (weathered) by water. In order to check the reliability of the instrument we compared He-pycnometer porosities with those obtained by

 | Song: The Perfect Drug Artist: nine inch nails Section: Break 2/Break 2A Very fun to play. It is easier than it looks so don't be too amazed ;) -------------------------------------- If you would like to talk to me, add me on MSN Messenger, my e-mail address is awfuldarkjedi@hotmail.com The way I record my videos with such high-quality, is because I use a Dazzle DVC 100. It captures audio and video straight from the TV so you don't hear other "outside the tv" noise. I do NOT play drums in real life but on Christmas 2008 I might be getting a drumset! So I may post some videos of me playing. Gamertag: AwfulDARK JEDI The mod that I currently have for my bass Pedal is the Roadie Pedal. And the mod for my pads that I have is the Sock Mod. Visit azuritereaction's channel for a tutorial on how to set up the Sock Mod. It works AMAZINGLY!
