The results indicate that the ratios of Ca, Mg, and K to one another in water and DTPA extracts of soilless media are good indicators of the availability of these elements to plants. Healthy specimens of the test plants grew in media whose DTPA extracts had a minimum Ca/Mg mole ratio of...
The relative increase in the 96-h Cu LC50 at higher Ca concentrations, but similar total hardness concentrations, was between 28 and 86% when the low Ca treatment was similar to American Society for Testing and Materials laboratory water (Ca:Mg molar ratio = 0.7). Failureto account for ...

12 This is typically addressed by training a classifier on one set of exemplars and testing it on the other.13,52 Such learning has been described as “abstract representation” or “deploying a schema,” and the ability to generalize rules across novel stimuli and contexts is thought to ...
and damage results from the breakage of silicate chains and calcium ions.Interlayer structure in z direction shows weakest loading resistance, due to unstable H-bond network and shielding Ca2+.Displacement of water layers under tension loading results in shrinkage and creep of cement at macro-level...
Calcium imaging with protein-based indicators1,2 is widely used to follow neural activity in intact nervous systems, but current protein sensors report neural activity at timescales much slower than electrical signalling and are limited by trade-offs bet
Effects of CAPS2 knockdown in the MHb on anxiety- and depression-like behaviors. (a) Experimental paradigm for behavioral testing of mice infected with the virus. (b) Schematic representation of the AAV vector engineered to induce CAPS2 knockdown. (c) GFP expression of AAV-sh-vehicle (CON) ...
Prototypes were mixed with distilled water. Materials were compacted inside round rubber moulds (9 mm-diameter, 1.2 mm-height). Following initial setting time of hydraulic cements which was determined according to the American Society for Testing and Materials (ASTM) standards for setting time of ...
