Spawning a hydroelectric plant
Article Abstract:
A hydroelectric facility is being constructed at the Columbia River's McNary Dam. The project aims to exploit the untapped source of water power at a fishway and save the salmonids passing through the fishway. The proposed power station is being built between the dam and the fish ladder. Computer simulations of water flow were conducted to come up with a turbine geometry that will meet the final water-passage specifications. The turbine will be operated at a slower-than normal rate to reduce water velocity and minimize vibrations that may be harmful to the salmonids.

The warranty alternative
Article Abstract:
Contractors traditionally are not responsible for the long-term performance of roadway or highway projects. Warranty contracting guarantees the integrity of a product and of contractors' responsibility to repair or correct any deficiencies for a number of years after the project is completed. State highway agencies with decreasing budgets and resources have resorted to methods such as warranty contracting to better allocate resources, enhance quality and promote innovation.

Alternative NAD (P) H dehydrogenases of plant mitochondria
Article Abstract:
Plant mitochondria has a highly branched electron transport chain that provides great flexibility for oxidation of cytosolic and matrix NAD (P) H. To understand NAD (P) H oxidation in plant mitochondria, knowledge of mitochondrial structure and compartmentalization is essential.
