To study the effects of early drought priming at 5th‐leaf stage on grain yield and nitrogen‐use efficiency in wheat (Triticum aestivum L.) under post‐anthesis drought and heat stress, wheat plants were first exposed to moderate drought stress (drought priming; that is, the leaf water potential reached ca. −0.9 MPa) at the 5th‐leaf stage for 11 days, and leaf water relations and gas exchange rates,...
In this study, wastes and minerals were incorporated into the production of bricks as a kind of waterpurifying substrate. The brick contained 72% clay, 10% bagasse, 10% steel slag, 5% zeolite, and 3% calcite by weight. The brick exhibited highly and hierarchically porous structure. It can remove phosphate and ammonium simultaneously from aqueous solutions with the maximum adsorption amount of 3.8...
Negative bias temperature instability (NBTI) recovery for pure-SiO2 and plasma-nitrided oxide (PNO)-based PMOSFET has been investigated at room and below temperature. It is found that the generated hole traps in SiON dielectric under NBTI stress has a broadened energy distribution than that in SiO2 dielectric. This broadened maybe due to nitrogen related traps (K center) In SiON. The traps' location...
An experiment was established in 1992 in eastern Ontario, Canada to determine the effects of crop rotation (continuous maize, soybean-maize and alfalfa-maize) and nitrogen (N) amendment [0, 100 and 200 kg N ha−1 of fertilizer (NH4NO3), and 50 and 100 Mg ha−1 (wet wt.) each of stockpiled and rotted dairy manure] on maize production and soil properties. From 1997 to 1999, an additional study was added...
