depletion technology
1Depletion-load NMOS logic — Depletion load nMOS/NMOS (n channel metal oxide semiconductor) is a form of nMOS logic family which uses depletion mode n type MOSFETs as load transistors as a method to enable single voltage operation and achieve greater speed than possible with …
2Depletion gilding — is a method for producing a layer of nearly pure gold on an object made of gold alloy by removing the other metals from its surface. It is sometimes referred to as a surface enrichment process.[1] Contents 1 Process 2 Variations 3 …

7Oil depletion — per major producing country. This model assumes world oil depletion remains constant at the 2004 level of 80 million barrels per day.[1] However, world oil depletion is currently (as of 2008) at 85 million barrels per day …
8Gas depletion — is the inescapable result of extracting and consuming natural gas since it is a nonrenewable natural resource. The number of years of natural gas left is estimated by the ratio of proven natural gas reserves to the current consumption rate.… …
9Uranium depletion — is the inescapable result of extracting and consuming uranium since it is a finite resource. The journal Environmental Science and Technology argues that the availability of high grade uranium ore will deplete over time making the fuel more… …
10Appropriate technology — (AT) is technology that is designed with special consideration to the environmental, ethical, cultural, social and economical aspects of the community it is intended for. With these goals in mind, AT typically requires fewer resources, is easier… …
