Insect-proofing during Building Construction

چکیده
TRUCTURAL AND HOUSEHOLD PEST S CONTROL in the United States requires annual expenditures of hundreds of millions of dollars and the services of 27,000 licensed pest control operators. Preventive measures against structural and household pests should be taken during the construction of a building, because such measures are most effective and economical at that time. Preventive measures fall into two general categories, depending on whether they are directed against (1) subterranean termites, which invade a building from colonies in the soil and which first attack in the substructure; or (2) a number of other insect species that spend either all or a considerable part of their life in the attic, wall voids, or in other enclosed spaces in various parts of the building. Construction procedures and other measures to prevent insect attack and damage differ considerably depending on which of the groups of pests they are directed against.

Proofing: Efficient SSA-based Java Verification
Verification is essential for assuring the integrity of a Java virtual machine when executing untrusted code. Existing verifiers decide whether or not a given bytecode program is safe. In contrast, we introduce the concept of proofing. Proofing does not change the semantics of programs that would have passed the original bytecode verifier. For programs that would have failed verification, our a...

متن کاملReliability Effects with Proofing of Tantalum Capacitors
In traditional tantalum capacitors, the construction consists of a tantalum anode, Ta2O5 dielectric, and MnO2 as the cathode. The benefit of having MnO2, as the cathode, is the self-healing effect it provides. The conversion of MnO2 to a higher resistive state allows fault sites within the dielectric to be shut off from the rest of the capacitor. To mitigate problems developed during reflow, it...
