What holds true for meadows would seem to apply to arable land, too: mixed cultures are more fruitful than monocultures.
西华大学高分子物理英文课件Chapter7 Yield & fracture of polymers。
Light-weight 2D format hyperspectral imagers operable from unmanned aerial vehicles (UAV) have become common in various remote sensing tasks in recent years. Using these technologies, the area of inte...
Monitoring forage yield throughout the growing season is of key importance to support management decisions on grasslands/pastures. Especially on intensely managed grasslands, where nitrogen fertilizer...
Breeding in plants and animals typically involves straightforward addition. As beneficial new traits are discovered—like resistance to drought or larger fruits—they are added to existing prized variet...
We present studies on a series of photosynthetic reaction center (RC) mutants created in the background of the Rhodobacter capsulatus D(LL) mutant, in which the D helix of the M subunit has been subst...
The effect of an applied electric field has been measured for the quantum yield of formation of the P[sup +]H[sup [minus]], P[sup +]Q[sub A][sup [minus]], and [sup 3]P states of nonoriented Rb. sphaer...
Radical-pair decay kinetics and molecular triplet quantum yields at various magnetic fields are reported for quinone-depleted reaction centers from the photosynthetic bacterium Rhodopseudomonassphaero...
We report the observation that the yield of a radical-pair reaction in the solid state can depend strongly on the orientation of the reactants in a magnetic field. This phenomenon is expected to be qu...
Contribution of Spin-Spin Interactions to the Magnetic Field Dependence of the Triplet Quantum Yield in Photosynthetic Reaction Centers.
This report describes how to optimize linear static control problems involving first and second moments and yield objectives for Gaussian distributions. These problems can be cast as second-order cone...
Precision echo sounder surveys of bathymetry and sediment thickness of Lee Creek Reservoir and Lake Shepherd Springs (northwest Arkansas) were combined with Geographic Information Systems (GIS) analys...
A study has been conducted in three sub-watersheds to model the spatial distribution of runoff and sediment yield. The basic structure of the model includes generation of runoff using SCS curve number...
This study compares the effects of slope information derived from three GIS software on sediment yield as estimated using AGNPS model. The three GIS software are IDRISI for Windows, ERDAS Imagine and ...
A two-factorial experiment was carried out on 6 groups (10 animals each) of Polish Black and White Holstein-Friesian cows in the transition period to determine the effect of glucogenic additive (G...
