While interest in the United States has focused on the aborting of hurricanes and to a lesser extent on rain-making, it appears that the major Russian interest is in hail prevention. A secondary effect of causing precipitation by cloud-seeding is the removal of clouds and of fog. It has been possible to create enough of a hole in a cloud and fog layer over an airport to enable planes to resume operations (Salt Lake Qty, Utah, December 1962). ... 

It is not impossible, for example in weather modification (rain making, hail prevention and fog dissipation), but almost through catalytic triggering. 

Hail guards of stiff hardware cloth mounted in a removable frame are used to prevent hail damage to the relatively soft fins in hail-susceptible areas. If damaged just slighdy the performance is not impaired. 

To achieve a good intrinsic visible fruit quality, biotic and abiotic stress to the trees has to be controlled. Therefore, conventional fruit orchards are often fitted with relatively expensive installations such as wind break hedges, hail nets, irrigation systems and wind machines for frost prevention, irrigation and liquid fertilisation facilities and wild animal fences. Apart from liquid fertilisation systems, most of these installations can also be installed in organic orchards and help to assure yield and quality security.

To Prevent the Hail Growing into the Toe. If tho nail of your toe he hard, and apt to grow round, and into the comers of your toe, take a piece of broken glass and scrape the top very thin do this whenever you cut your nails, and, by constant use, it m cs tho comers fly up and grow fiat, so that it is impossible they should give yon any pain. Do not fiul to try this. 

The letter proposed that "until the potential hazards of such recombinant DNA molecules have been better evaluated or until adequate methods are developed for preventing their spread, scientists throughout the world join with the members of this committee in voluntarily deferring [certain] experiments." This request by scientists for a voluntary "moratorium" on such work while questions of safety were further evaluated was widely hailed in the press.

Roofing materials are exposed to harsh conditions, which cause degradation in properties over time. Deterioration occurs due to wind damage, sunlight exposure, rain, snow, hail, and temperature variations [20]. To prevent, or at least slow down these processes, thermal and UV stabilizers, antioxidant materials, and flame retardants are added to the plastic in appropriate amounts. PVC membranes also contain plasticizers for flexibility.
