Two models of protein folding are currently being confirmed: 1  The diffusion collision model, in which first a nucleus forms, then the secondary structure, and finally these secondary structures collide and pack tightly together. 2  The nucleation-condensation model, in which the secondary and tertiary structures of the protein are made at the same time.
Air Currents: If there are fans, wind , or other sources of air movement, gases may tend to rise or collect in certain areas of a facility. The local air currents should be assessed to aid in selecting the sensor location. Air convection can often be more important in determining gas concentration areas than factors of vapor density. Gas Emission Sources: As a rule, at least one sensor shouold be located in close proximity to each point where an emission is likely to occur.
Quick Facts. The Coso volcanic field is located about 160 km (100 mi) northeast of Bakersfield, California, mainly within the boundary of the Naval Air Weapons Station, China Lake.t covers approximately 400 km 2 (roughly 150 mi 2) and is home to one of the largest producers of geothermal power in the U.S., with an output sufficient to supply the needs of 270,000 homes.
