One case tests the constitutionality of the Child Online Protection Act, a 1998 law that makes it a crime to transmit, for commercial purposes, material over the Internet that is "harmful to minors".
Our findings suggest that inter-organisational links served two important and complementary purposes: material and symbolic.
The CIA's analysis was seldom double-checked; detection of dual-purpose materials, that might possibly be used in weapon programmes, was routinely taken as proof that such programmes existed; and ambiguous scraps of intelligence were compiled to reach an unambiguous conclusion, a process known as "layering".
Guidelines to develop on-purpose materials are given from thermodynamics and material state of the art.
For this purpose, materials based on AC-44200 alloy reinforced with Al2O3 particles were made using the squeeze casting method.
Magnetic properties of various G-FRP Dewar-purpose materials are explored with a χ-meter furnished with a RF SQUID magnetometer.
Modern construction projects are complex engineering structures that vary in purpose, materials, height, the regulatory period of service, purpose and features of operation.
Modern construction projects represent complex engineering structures that vary in purpose, materials, height, the regulatory period of service, purpose and features of operation.
Nowadays, ethanol is an attractive renewable energy that can be produced from multi-purpose materials such as rice, sweet sorghum, sugar cane or even substrates from food industrial waste.
For that purpose, materials ought to be close enough to whoever needed them.
