To determine the transmissivity of solar radiation, incident global radiation was measured throughout the production cycle of soybean with a pyranometer coupled to a datalogger (LICOR 1400), measuring from 10:00 am until 12:00 noon.
Estimating aquifer transmissivity in a basin based on stream hydrograph records using an analytical approach.
- By using SKe-Lid as a cover material for quartz glass (also compatible with glass with AR codes), the transmissivity of high-output deep ultraviolet LEDs can be increased.
Also, the performances of these models when considering several locations spread in the country were a bit worse than those reported by specific locations [51-53], which is mainly caused by the greater [Q.sub.g] variability observed around the country with the different atmospheric transmissivity caused by diverse cloud types.
[[tau].sub.atm] is the transmissivity of the atmosphere in the infrared spectrum.
The greenhouse had 50m of length, 7m of width, 4m of height (north-south direction), divided in two environments: Environment I (EI)--covered with low-density polyethylene film (solar radiation (SR) transmissivity: 80%) associated with thermoreflective screen (SR transmissivity: 57-60%), installed internally at the ceiling height; Environment II (EII)--covered with a diffusive plastic film (SR transmissivity: 60%).
In that work sapphire emission was excluded from the infrared recordings by using two filters of center wavelength 3.275 [micro]m and 3.86 [micro]m, where sapphire was expected to have high transmissivity. Glass and like materials become opaque in the region of about 4-5 [micro]m [23].
The well response depends on the flow of water through the porous medium and therefore is sensitive to the aquifer transmissivity and storage.
where [T.sub.fi] is the transmissivity of fracture and [x.sub.i] is the local coordinate of fracture.
The sensitivity analysis showed that recharge and transmissivity of the aquifer were most sensitive parameters.
