Our results suggest that plant functional types capture much of the variability required to predict the seasonal patterns of evapotranspiration among cities, as well as differences in evapotranspiration that could result from changes in climate, land use, or vegetation composition. 1. Introduction [2]...
All in all, Cat6a can perform just about the same as Cat7 but at a lower price point. Most of our AV and IP surveillance customers opt for Cat6a STP or Cat6a FTP. Both offer shielding from alien crosstalk and interference around high voltage lines. Cat7 is suited for use in datacente...
is one of the most popular grain crops in the semiarid Loess Plateau region, but low air temperatures and drought in April and May often results in poor plant establishment. In dryland farming systems, plastic-film mulching has been used for the micro-catchment of water and to increase ...
The influence of water type was similar for both the acute screening and definitive plant tests. No effect of water type on seedling emergence was observed. Shoot growth was greater in barley watered with nutrient solution, but no difference was observed among other water types. Root length was...
