Brief Communications HIGHER FOLATE INTAKE IS RELATED TO LOWER RISK OF ALZHEIMER'S DISEASE IN THE ELDERLY

What is new in the art to which my invention pertains is that it allows for a repair or restoration of a pressure retaining item that has local material degradation to an acceptable state of condition for continued operation without the need to cut out the degraded section of material or breach the pressure boundary of a pressure retaining item. Common methods of repair include removal of degraded or affected material section and replacement with a new section of equivalent material by joining the new material to an existing item at a location of adequate thickness using full or complete penetration welds. This type of repair may be referred to in the industry as a "flush patch repair". An additional type of repair where a section of material degradation may be localized is a "weld build-up repair' wherein weld metal is deposited onto the existing area of affected material to return the material to its original thickness. Both "flush patch repair" and weld build-up repair" methods require breaching of the pressure boundary integrity of a pressure retaining item to implement a repair. The invention does not require breaching a pressure boundary.
