Designing polymeric photocatalysts at the molecular level to modulate photogenerated charge behavior is a promising and challenging strategy for efficient hydrogen peroxide (H2O2) photosynthesis. Here, we introduce electron-deficient 1,4-dihydroxyanthraquinone (DHAQ) into framework of resorcinol-formaldehyde (RF) resin, which modulates donor/acceptor ratio from perspective design promoting sepa...

Based on both theoretical and practical experiences, the measures aimed at controlling emergency shutdowns of stopes have been highlighted. These are connected with rigid settlements powered complexes. In terms Western Donbas mines, there certain risks a shutdown stopping operations within zone primary roof caving. Thus, causes support may include following: layers main rocks hanging not timely...

This paper examines the use of a hierarchical coevolutionary genetic algorithm under different partnering strategies. Cascading clusters of sub-populations are built from the bottom up, with higher-level sub-populations optimising larger parts of the problem. Hence higher-level sub-populations potentially search a larger search space with a lower resolution whilst lower-level sub-populations se...

Educators and administrators often use sub-scores derived from state accountability assessments to diagnose learning/instruction and inform curriculum planning. However, there are several psychometric limitations of observed sub-scores, two of which were the focus of the present study: (1) limited reliabilities due to short lengths, and (2) little distinct information in sub-scores for most exi...

Wide-range level shifters play critical roles in ultralow-voltage circuits and systems. In this paper level shifter circuits that are capable of converting subthreshold to above threshold signal levels are presented. Level shifters are designed using current mirrors. The circuit has a distinctive current generation scheme using a logic error correction circuit that works by detecting the input ...

In this study, the response of selected almond cultivars on different rootstocks under drought stress base on Morpho-physiological traits using a factorial experiment in a randomized complete block design with three replications was investigated. The experimental was carried out at the Temperate Fruit Research Center of Horticultural Sciences Research Institute (HSRI) in 2016. The factors inclu...
