Hail stones

These four unfortunate guys may be interested in yet another acetylene connection — one that involves the idea of getting stoned. French researchers have found a way to reduce crop damage caused by hail. They have developed a gun equipped with a combustion chamber in which acetylene mixes with air to create an explosion the gun s hornlike barrel is aimed upward to send a shock wave into the clouds. A series of such shock waves breaks up the hail stones, ensuring that the crops below — and people — don t get stoned. [Pg.157]

The dust which is carried down with rain, hail, or snow has been analyzed by many. W. Stark, A. F. Wiegmand, W. L. Zimmermann, R. Braudes, C. Bertels, J. D. Bohlig. etc., noted the presence of calcium salts—chiefly sulphate—in rain-water J. Girardin, in hail-stones and A. F. Wiegmand, in snow-water. The last-named also noted the presence of phosphates in atm. dust—vide infra, chlorides, etc. A. Ditte, and W. N. Hartley and H. Ramage have discussed the occurrence of metals as well as meteoric dusts in the atmosphere. [Pg.2]

The four elements by their manifold combinations make up all the material universe. Water, thinks Plato, by heat is converted to vapor and eventually into air by cooling, on the other hand, it is converted into snow or hail or ice and under the earth, by heat or cold and pressure, it may be converted into rocks or stones. [Pg.123]

On the inside of the second circuit, that is to say of the second ring of buildings, paintings of all kinds of precious and common stones, of minerals and metals, are seen and a little piece of the metal itself is also there with an apposite explanation in two small verses for each metal or stone. On the outside are marked all the seas, rivers, lakes, and streams which are on the face of the earth as are also the wines and the oils and the different liquids, with the sources from which the last are extracted, their qualities and strength. There are also vessels built into the wall above the arches, and these are full of liquids from one to 300 years old, which cure all diseases. Hail and snow, storms and thunder, and whatever else takes place in the air, are represented with suitable figures and little verses. The inhabitants even have the art of representing in stone all the phenomena of the air, such as the wind, rain, thunder, the rainbow, etc. [Pg.59]

Discussions about the current and general scope and limitations associated with MIPS are ongoing. For a while, a good number of pubUcations were of two minds in their assessment of the potential of MIPs, where small advances in performance were hailed as stepping stones to rival, if not excel, antibody and enzyme methods. This was followed by a healthy sobering period. Over the last ten years a much more reafistic assessment of the potential of... [Pg.215]
