Ordinary tin is composed of nine stable isotopes 18 unstable isotopes are also known. Ordinary tin is a silver-white metal, is malleable, somewhat ductile, and has a highly crystalline structure. Due to the breaking of these crystals, a "tin cry" is heard when a bar is bent. 

No mechanistic aspects of organic chemistry (or, for this reason, any reaction intermediates) were ever mentioned by Zemplen in his lectures or writings, nor did he consider or accept their existence. I never heard him mention the names of Meerwein, Ingold, Robinson, or any other pioneers of the mechanistic electronic theory of organic chemistry. The possible role of organic ions was similarly never mentioned. He was. 

METHOD 3 Things start to look easier and the yields higher when the following method is employed [122]. This method uses a solvent called DMSO (dimethylsulfoxide). Maybe you ve never heard of this solvent but Strike has. It is a common solvent used in all fields of science and although Strike is not 100% sure. Strike believes that one can substitute DMF (dimethylformanilide) for DMSO. 

Incident Details Describe in your own words circumstances leading lo the incident, what happened during the incident, what happened after the incident, personal sensations such as what you saw, heard, tasted, or smelled. 

Maybe you ve heard your auto mechanic say on installing a new radiator watera or alternator onto your car. .. that if it runs for 5 minutes, then it will run for i i years. If It s going to fail, it will do so within the first five minutes. 

Water hammer is not always accompanied by noise. Some types of water hammer, resulting from localized abrupt pressure drops, are never heard. The consequences, however, may be just as severe. 

Atrophy Atrophy is a wasting or decrease in size of a bodily organ, tissue, or part owing to disease, injury, or lack of use. You may have heard this term used in reference to accident or paralysis victims "his muscles atrophied because of nonuse." Exposure to certain chemicals can cause internal organs to degrade, weaken and decrease in size, particularly with chronic (long-term) exposure. 

You may have heard other terms sueh as job safety analysis (JSA), aetivity hazard analysis (AHA), or task-speeifie hazards analysis (THA). No matter what you eall the term, a job hazard analysis (JHA) is a proeess that ean used to help develop safe work praetiees or proeedures. 

A more eomplieated or dangerous site will require a more extensive orientation. A seasoned erew on a site where the hazards are eonsidered low would not require the same length orientation as a nonexperieneed erew at a site they had never seen or heard of Initial orientation on a large, eomplieated or extremely hazardous site may take several hours or... 

The plant employed 119 people in three shifts, but only 30 were there when the explosion occurred. Terra s plant produced about 12% of the U.S. nitrogen-based liquid solution fertilizer. About one half of the plant was totally destroyed, the other half of the plant was damaged. The explosion was heard 50 to 60 miles away and shook Sioux City. 

Another somewhat similar incident occurred when butadiene from a reactor flowed in the wrong direction up a line used for adding emulsifier. The check valve, which should have prevented the flow, was obstructed. The emulsifier tank was in a building and had an open vent. Butadiene came out and exploded. The explosion was heard 15 km away, but damage was minimized by the light construction of the building, w hich ruptured at the junction of the roof and walls [13]. 

Also in 1815, but before Davy presented his first lamp to the public, George Stephenson (one of the pioneers in the development of the steam locomotive) quite independently was also working on a safe miner s lamp. He discovered during his experiments that flame produced by a particular gas at a given concentration will not pass through a tube smaller than a certain diameter. While most people have heard of Davy s lamp (it seems that Sir Humphrey received all the credit), it was actually Stephenson s discov-... 

The fire destroyed a farmhouse, six outbuildings, and an automobile. Two other houses and a car were damaged. Two persons died in the farmhouse. Three persons who lived across the highway from the rupmred pipeline had heard the pipeline burst and were fleeing their house when the propane ignited. All three persons received bums on over 90% of their bodies, and one later died from the bums. Fire departments extinguished smaller fires in the woods and adjacent homes. 

The tank truck left the road near the campsite and crashed at 4 29 p.m. (Figure 2.29). Propylene seems to have been released. The resulting vapor cloud was ignited, possibly by camp cooking hies. One or two explosions then occurred. (Some witnesses heard two explosions.)... 

Heard explosion which was then followed by control room damage, including windows blowing in. 

Heard loud explosion. Ran to control room and found that the windows had been blown in. Supervisor then sounded plant alarm. Then went to separation module and found it severely damaged and on fire.
