Q: DENNY CRANE!: I used to be a fan of Boston Legal... until they got too political... but this is just a goofy question.

Q: The war is during 1899, and it's not the Spanish-American war.This isn't assignment, I'm just curious to know.: Sounds like War to me According to the black and bare lands, with women and babies weeping , etc. A person in the midst of this upheaval..the only one it seems Evidentely was ask milions of questions of why Because he was the only one who asked Why? He did not know the answer but he was the only one who cared..to me this is the meaning of the poem Stephen Crane wrote some brain teasing material..Read In the Desert

Q: i have an echo-1 m8a4 cqb it has a crane stock that fits a 9.6 1500mah battery but it wont fit a 2000mah so i want to switch to a full stock but im haveing trouble figuring out how to switch them. does anyone own this gun and know how to do it?: Ok, I can help. The first step is to take the crane stock off. To do so, extend the stock fully. Then, take the tab you use to extend it, and instead of pushing up to extend it, pull it down and slide the stock off. It make take some force. Be careful of any wires and that you don't break them! Next: take the buffer tube out. Take a long phillips head screw driver and stick it down the shaft. Remove the screw. The whole tube should come out. Don't lose the screw! Next: Install your stock. Next: Screw the screw back in to secure the stock. Done! Make sure the wires are still ok and that they are not pinched!

Q: What is the calibration value of a tower crane?: Do you mean the calibration value of crane lifting moment? That should be the product of the maximum magnitude of the tower crane and the corresponding maximum lifting load.

Q: What is the scrap standard of tower crane hook?: The American Standard can provide for your reference:1, hook hanging points in the effective area of cross sectional wear more than 10%, should be disabled and scrapped.2 any visible permanent deformation and cracks shall be disabled and scrapped.3, if the wear is in the same area in two directions, it should be controlled within 5%.4, any hook opening deformation is not greater than 5%, or in accordance with the manufacturer's guidelines to determine.5, hook bow hook (i.e. intermediate position hook C shape) wear amount should be less than 5%.

Q: They like fly on peoples face, i dont know why they come up on the face and it creeps me out, i have no idea why it comes inside of the house in the first place?: How To Kill Crane Flies

Q: a. its season of migrationb.the route it followsc.how is it guidedd.distance it travels in a yeare.reason behind migrationplz help me..ill be highly grateful!!!!: This species breeds in arctic Russia in Yakutia and western Siberia. It is a long distance migrant. The eastern population winters on the Yangtze River in China, the central population at Keoladeo National Park, India and the western population in Fereidoonkenar and Esfahan in Iran. It breeds and winters in wetlands, where it feeds on the shoots, roots and tubers of aquatic plants. This is a large white crane. Large males can exceed 140 cm (55 inches) in length and weigh over 10 kg (22 lbs). Adults are all white, except for a dark red mask extending from the bill to behind the eye. It has a yellow iris and reddish legs. The male is slightly larger than the female. Juveniles have a feathered mask and buff or cinnamon plumage. The voice is flute-like and musical. The status of this crane is critical, as it is expected to undergo a rapid population decline in the near future. The wintering site in China holding 95% of the population is threatened by hydrological changes caused by the Three Gorges Dam. Historic records from India suggest that a number of them wintered there in the past. This number has steadily declined and the birds are no longer found there. Mr. Rutledge of Entally told me that for twenty years he tried unsuccessfully to get live specimens of this crane, but did not succeed till a few years ago, when he and one of the native dealers got so many that the market was quite glutted, and many were sent to Europe. Since then the bird got scarce again, so this was evidently only a temporary invasion. —Frank Finn, Frank Finn in How to know the Indian waders. 1906 The Siberian Crane is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies and is subject of a Memorandum of Understanding concluded under the Bonn Convention. =]

Q: Okay, well obviously, in The Legend of Sleepy Hollow,he was ugly, but wat exactly made him ugly?? it tells you, but its way too complicated for me. Could anybody just make it... simpler?: His okorder /

Q: A. Power LinesB. WaterC. FiresD. Overturns: Um, caused by operators who get their training on Yahoo Answers? Overturns are more dangerous to others, a couple years ago a crane killed someone in an apartment across the street from where the crane was working, in a city not far from where I live, but the operator survived. However power lines might be more dangerous to the operator since I suspect they happen more often.

Q: What did Stephen crane contribute to history?: I think his greatest contribution was The Red Badge of Courage. It was the most ealistic portrayal of a Civil War soldier written at the time; so real, in fact, that veterans swore the had fought alongside him during battle (Crane wasn't even alive during the war).
