The armored scales (Family Diaspididae) constitute one of the most successful groups of plant-parasitic arthropods and include some of the most damaging and refractory pests of perennial crops and ornamentals. The Diaspididae is the largest and most specialized of the dozen or so currently recognized families which compose the superfamily Coccoidea. A recent world catalog ( 19) lists 338 valid ...

High solids content film-forming poly[styrene-co-(n-butyl acrylate)] [poly(Sty-co-BuA)] latexes armored with Laponite clay platelets have been synthesized by soap-free emulsion copolymerization of styrene and n-butyl acrylate. The polymerizations were performed in batch in the presence of Laponite and a methyl ether acrylate-terminated poly(ethylene glycol) macromonomer in order to promote poly...

and-held GPS receivers are used by soldiers to find their way in strange lands, especially at night. H GPS receivers are also used to find downed pilots and locate other strategic personnel. After the Gulf War, the U.S. Army announced it would install GPS in all armored vehicles to help minimize friendly fire incidents, which was a major source of casualties in Operation Desert Storm. Friendly ...

The National Automotive Center (NAC) Ground Vehicle Simulation Laboratory (GVSL) is developing and applying engineering simulators and simulations for the evaluation of ground vehicles during all stages of a weapon system’s life cycle research, development, and procurement of new systems; technology insertion and modifications to fielded systems; and trouble-shooting activities arising from tes...

The Composite Armored Vehicle (CAV) is an advanced technology demonstrator of an all-composite ground combat vehicle. The CAV upper hull is made of a tough light-weight S2-glass/epoxy laminate with embedded ceramic tiles that serve as armor. The tiles are bonded to a rubber mat with a carefully selected, highly viscoelastic adhesive. The integration of armor and structure offers an efficient co...

A method of calculating the effect vibrations sprung body and operation suspension system an armored combat vehicle on its autonomy has been developed. One main indicators is power reserve, which depends specific fuel consumption. In process moving over bumps, a significant part plant's energy, accordingly fuel, spent occurrence machine unsprung masses. Then energy these converted into heat in ...
