Since it is common for casing pipes materials exposure in the H2S/CO2 environment like Puguang gas field, the cracking sensitivity of C110 after cold hardening is very important.
The product has a number of eco-features, such as using LED as its lighting source and recycled polyethylene terephthalate (PET) material for its casing.
The sugars used most widely as casing materials for tobacco are sucrose and invert sugar (the hydrolysis product of sucrose, mainly glucose and fructose).
"Nanocomposites" made of natural materials, could one day be used for casing and circuit board construction, and are in development, as are adhesives made from marine organisms that could improve the construction and disassembly process for electronic devices.
The specific surface area of the starting material influenced the reaction rate; therefore, to obtain a comprehensive kinetic analysis for reactions using any form of aluminum materials (powder, casing, and foil), the reaction rate constant was calculated per unit of surface area (k′) for each reaction condition (Table 3).
In addition to the casing integrity, radial and tangential stresses for casing, cement and formation are presented.
Tarnished metal, bullet casings, and magnets sound like materials for a post-apocalyptic war machine, but in the hands of new media design group PanGenerator, they're quite the opposite.
One year old next January, his company PocketQube Shop provides the basic materials for doing this, most importantly the PocketQube structure itself - a tiny, 5cm³ casing made from aerospace-grade aluminium – which houses each satellite's components.
The HOC made an initial purchase for supplies and stock from existing programming funds to get the program started, but after that, a portion of the casings that the worms produce are exchanged with a vendor for fresh materials for further processing at no cost to the HOC.
For a typical liner material, the penetrated casing hole size is related to the liner geometry, the amount of the explosive charge, and the shape as well as the thickness of the charge case.
