However, limited transformation into other humic substances potentially occurred, but could not be quantified because the yield of the CuO oxidation method proved somewhat variable with incubation time.
Wines made from older vines also tend to have more texture, because the yield of grapes is lower; younger vines, meanwhile, can be "green harvested" to reduce the number of bunches of grapes and make the juice more intense.
In SIRIS devices the secondary ions are rejected because the yield of these ions can be greatly affected by the composition of the host material (known as the matrix effect).
Livestock was raised for use as draft animals and for food, and, because the yield of the grainfields did not greatly exceed human requirements, stock was pastured on poor land or harvested fields.
Today, however, the tax advantage of municipals makes sense for people in any tax bracket, largely because the yield of municipal securities with maturities of five years or more is nearly the same as the before-tax yield on comparable United States Treasury securities for the first time in more than a decade.
Because the yield of the Al/ZrO2/Pt device fabricated at RT is higher than that of the other samples, more detailed investigations focused on this device are shown as follows.
We assume the energy output of CNPC, Sinopec, and Yanchang is 3.89 × 104 MJ, then that of CNOOC is 2.14 × 104 MJ, because the yield of light oil products for CNOOC is lower about 1.75 × 104 MJ per tonne than that of other companies.
Because the yield of -menthol N-acetylglucosamine was too low, the structure of -menthol N-acetylglucosamine was determined using only MS/MS and HR-ESI MS data (m/z 382.3 [M+Na]+, 360.3 [M+H]+, 204.2 [N-acetylglucosamine+H] +; HRESIMS: m/z 360.2385 (M+H +, calcd.
This is largely a result of increasing CO2 loss with increasing relative frequency of carboxylates because the yield of both backbone fragments and oxidized molecular ions decreases nearly linearly with increasing relative frequency of carboxylates.
