Disposal of low-level radioactive waste.

The Act encouraged states to form regional compacts for the disposal of low-level radioactive waste (LLRW). The Act contained both positive and negative incentives. The positive incentive was a provision that allowed compacts to restrict access to their regional LLRW disposal facility to member states beginning in 1993, thus limiting the amount of waste disposed of in any state hosting a region...

A Novel Low Voltage, Low Power and High Gain Operational Amplifier Using Negative Resistance and Self Cascode Transistors

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...

Performance evaluation of waste fried vegetable oil in a medium grade low heat rejection diesel engine

Investigations were carried out to evaluate the performance of direct injection diesel engine with medium grade low heat rejection (LHR) combustion chamber and 3 mm air gap insulated piston, 3 mm air gap insulated liner, and ceramic coated cylinder head [ceramic coating with the thickness of 500 µ was made on the inside portion of the cylinder head].The engine had different operating conditions...
