Second crash

This experiment does have some features of a direct vision observation. First, the glowing spot is directly visible. Second, it is easy to imagine an invisible stream of particles hurtling through the triangular hole in the electrode to crash against the fluorescent screen in a burst... 

Requires little maintenance, while providing long-term durability. Crash beams have a slower response time (normally 9.5-15.3 seconds, but can be reduced to 7-10 seconds in emergency situations) than do other types of active security barriers, such as wedge barriers. Because emergency activation of the barrier causes more wear and tear on the system than does normal activation, it is recommended for use only in true emergency situations. 

That was the second crash landing by a fledging research bird attempting initial flight. I affected unconcern about my lack of success. That may be one reason Dr. Rioch called me over to his office a year later.

A friend at work said it should not be hard to actually pronounce the secret four-letter name of God, the Tetragrammaton miT , by having his computer consider every possible vowel, or phoneme, combination with the four consonants. He coupled the output of his computer to a speech synthesizer, so the computer would actually speak the words at a rate of one name per second. At some point, he theorized, the computer should say the name of God. My friend was not concerned about the wrath of God because it was the computer uttering the name of God, not him. During one vocalization, my friend s computer crashed. He stopped the experiment and never ran the program again. 

Tho mechanical constitution of the two products does not come so directly under the consideration of the chemist. The Editor will, therefore, merely give tlie results of some experiments which were laid before the British Association a few years ago. In the following table, the second column shows the force in1 pounds necessary to crash a cylinder, the transverse section of which is a square inch the diird column, gives the force in pounds, which is required to tear asunder the same cylinder and the ratios of these forces are shown in the fourth column —... 

Goepp, Jr.,1 a book entitled The Chemistry of the Carbohydrates. Because of Dr. Isbell s withdrawal and Dr. Goepp s death in an airplane crash in 1946, Pigman was left to complete the book alone. This book,2 published in 1948, was destined to become the standard reference on the subject, and to establish Pigman as an authority on sugar chemistry. It was to be followed, in 1957, by a multi-authored volume, The Carbohydrates, edited by Pigman its success prompted a second edition of The Carbohydrates, in four volumes, which he edited in collaboration with Derek Horton. 

Many cocaine addicts use downers to come off a high in order to avoid crashing. They often use drugs such as alcohol, Valium, or heroin, creating a vicious cycle and becoming dependent on the second drug. 

A few seconds after the administration there is a subjective euphoric phase (rush), a feeling of extreme pleasure and comfort. Then a rapid rebound of the cortical depression (down) leads the subject to a condition of anxiety, depression, and irritability. When regularly used, the physical and psychological discomfort that accompanies the end of the effects is configured as a real abstinence syndrome (crash), whose main symptoms are depression, physical breakdown, irritability, and above all the compulsive and uncontrollable desire for cocaine. 

As discussed in Chapter 4, emulsion polymerization received a significant boost in the United States during the Second World War. When Japan overran countries that supplied natural rubber to the West, a crash program to manufacture synthetic rubber was initiated in the United States and Canada. The product was called Government Rubber-Styrene (GR-S), and was produced by the emulsion polymerization of butadiene and styrene. The fundamental recipe for GR-S is still used as a teaching tool for those learning the art and science of emulsion polymerization. 

The difference between the crash rates per mile in the first two reports is due to the use of a bounding rate (using general data) in the first report and a carrier-specific rate in the second report. The third report derived a truck crash rate per billion ton-miles, based on Federal Motor Carrier Safety Administration data for the number of commercial vehicle hazmat crashes divided by the number of commercial vehicle ton-miles. The commercial vehicle accident rate per ton-mile value was multiplied first by 0.59 and then by 0.013 to account for the number of ton-miles for for-hire commercial vehicles and for Class 6 poisons, respectively. These adjustments to the accident rate are inappropriate without consideration of the corresponding hazmat crashes, for which no data were used. The total accident scenario probabilities may be conservative (too high), however, when the probabilities of fire occurring, impact forces sufficiently high, etc. are considered. These probabilities do not appear to have been addressed, and the committee did not review the reports at that level of detail. 

In the early 1980 s a neoprene-type foam (VONAR) made by Du Pont was developed specifically for use as a comfort cushioning material for critical applications where low flammabUity was required, such as in transport aircraft seat cushions. This material is designed for use over flame-retardant polymethane foam and is believed to provide 50 seconds more of evacuation time in the event of a post-crash fire. VONAR has a density of 10.66 Ib/ft , compared to 7-8 Ib/ft for standard neoprene foam, and 1.2-2 Ib/ft for polyurethane foam (5).
