Shielding a room using aluminum foil
A local hospital was interested in shielding some sensitive equipment and contemplated installing a shielded room. The room under consideration was the typical laminated wood core panel with galvanized steel on both surfaces, with a RF shielded door, honeycomb air vent panels and filters for ac power, telephone and any other signals, meeting the shielding effectiveness requirements of MIL-STD-2...
متن کاملSmall-intestine Perforation with an Aluminum-foil Foreign Body
We present the first case documented in the literature of perforation of bowel due to drug tablet with package ingestion. A diagnosis of perforation was made by CT imaging revealing a staple-like foreign body with air-content in the distal ileum. Adjacent abscess with free air formation also noted. This is an unusual case of small intestine perforation due to a foreign body that was preoperativ...
متن کاملNon-linear Transient Heat Conduction Analysis of Insulation Wall of Tank for Transportation of Liquid Aluminum
This paper deals with transient non-linear heat conduction through the insulation wall of the tank for transportation of liquid aluminum. Tanks designed for this purpose must satisfy certain requirements regarding temperature of loading and unloading, during transport. Basic theoretical equations are presented, which describe the problem of heat conduction finite element analysis, starting from...
متن کاملExperimental Study of Fire Hazards of Thermal-Insulation Material in Diesel Locomotive: Aluminum-Polyurethane
This work investigated experimentally and theoretically the fire hazards of thermal-insulation materials used in diesel locomotives under different radiation heat fluxes. Based on the experimental results, the critical heat flux for ignition was determined to be 6.15 kW/m² and 16.39 kW/m² for pure polyurethane and aluminum-polyurethane respectively. A theoretical model was established for both ...
متن کاملThe Stardust Interstellar Dust Collector Crater Origins and Hypervelocity Cratering at Oblique Angles in Aluminum Foil
From 1999 to 2006 the NASA Stardust mission collected cometary particles from the Wild 2 comet and interstellar dust from the interstellar medium in two collectors made from aerogel tiles and aluminum foil. By studying their isotopic compositions, these particles can provide us with information about nucleosynthetic processes in stars. Both collector trays are being studied for traces of these ...
