The capacity of human sensory systems for transmitting information has been approximated in the past by using statistical estimators. However, a substantial margin of error remained. The problem is that the error can be reduced to a negligible level only by increasing the number of human trials or tests to the order of about 10(4). Since a human subject can perform at peak only in the order of ...

Labor force participation rates of married women have increased substantially since 1950s; and the educational gender gaps for cohorts born after 1950 have also witnessed a shrinkage and, in fact, a reversal. In this paper, we advance a novel connection between the two trends: the decrease in the maternal time input in the children’s education as a result of the increase in maternal employment ...

a number of 36 varieties of rice were compared for different traits. the correlation coefficient of grain yield with tiller number, harvest index, length of grain, ratio of length to width of grain, amylase content, days to 50 percent flowering and days to full maturity were positive and significant (p

ABSTRACT In this paper I summarize our recent investigations (Park and Kim, Phys Chem C 111:14903, 2007; Solid State Ionics 179:1329, 2008) on the origin of the grain-boundary resistance in a doped LaGaO3, a perovskite-structured solid electrolyte. The partial electronic and ionic resistances of the bulk and the grain boundaries, as well as the total resistance, in 1 mol% Sr-doped LaGaO3 were m...

Twenty multiparous Holstein cows, 4 of them surgically fitted with ruminal cannulas, were used in a replicated 4 x 4 Latin square to compare the effects of whole-plant silage and grain produced from NutriDense (ND), leafy NutriDense (LND), or a conventional yellow dent (YD) hybrid on ruminal fermentation, total tract nutrient digestibility, and performance of lactating dairy cows. On a DM basis...
