Ecological aspects of the state of natural and technical systems in the zone of irrigated agriculture effect

The purpose of the study is to identify the ecological aspects of the state of natural and technical systems in the zone of irrigated agriculture effect on the example of the hydrographic network of the left bank of the Lower Don. The Semikarakorsky district of the Rostov region was chosen as the object of the study. The subject of the study was the water quality in natural-technical systems – receivers of collector-drainage runoff from reclaimed lands, collector-drainage network, irrigation channels, as well as hydrochemical indicators of groundwater with a depth of no more than 5 m, soils from irrigated fields and fields with natural irrigation (boghara). The analysis of the results showed the widespread effect of groundwater on the formation of the drainage runoff and natural water composition, the accumulation of sodium ions and sulfates in soils, which is due to the rise of the capillary fringe due to the rise of the groundwater level. In general, the chemical composition of drainage water corresponds to the geochemical background of the territory and is a consequence of their natural desalinisation

Cyclometallated 1,2,3-triazol-5-ylidene iridium(III) complexes: synthesis, structure, and photoluminescence properties

A series of heteroleptic cyclometallated 1,2,3-triazol-5-ylidene Ir III complexes were synthesized and structurally characterized. These new complexes demonstrated photoluminescence in green (550 nm) and cyan (499, 496 nm) regions. Their photophysical properties were rationalized using DFT calculations. © 201

Tiered Information Disclosure: An Empirical Analysis of the Advance Peek into the Michigan Index of Consumer Sentiment

This paper studies market microstructure implications of informed high-frequency traders (HFTs) from two seconds of advance peek into the Michigan Index of Consumer Sentiment (ICS), provided by Thomson Reuters to its elite customers. Using individual stocks in the NASDAQ data set, we show how HFTs trade around ICS events. We find that liquidity demanders during two seconds of advance peek earn substantive profits, which are consistent with the notion that HFTs\u27 informational advantages may increase adverse selection costs for other market participants. This evidence elucidates the debate on regulatory oversight and its role in circumventing the potentially adverse effects from an advance peek into ICS
