The mol-ecules of the title compound, C15H14N2O3, possesses crystallographically imposed twofold rotational symmetry, so the asymmetric unit contains one half-mol-ecule. The fused-ring system deviates significantly from planarity; the planes of the five- and six-membered rings are twisted with respect to each other by 3.0 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules related b...

BACKGROUND Preoperative malnutrition is increasingly prevalent in patients undergoing cardiac surgery. Although prealbumin is a widely used indicator of nutrition status, its use in the preoperative assessment of patients undergoing cardiac surgery is not well defined. The purpose of this study is to determine the impact of preoperative prealbumin levels on outcomes after cardiac surgery. MAT...

Recently, yield shocks due to extreme weather events and their consequences for food security have become a major concern. Although long time series are available in Europe, few studies been conducted analyze them order investigate the impact of adverse climate on under current future conditions. Here we designated lowest 10th percentile relative anomaly as shock analyzed subnational wheat acro...

The classical Gumbel probability distribution is modified in order to study the failure times of a given system. Bayesian estimates of the reliability function under five different parametric priors and the square error loss are studied. The Bayesian reliability estimate under the non-parametric kernel density prior is compared with those under the parametric priors and numerical computations a...

Since second-order probability distributions assign probabilities to probabilities there is uncertainty on two levels. Although different types of uncertainty have been distinguished before and corresponding measures suggested, the distinction made here between firstand second-order levels of uncertainty has not been considered before. In this paper previously existing measures are considered f...

This study assessed the impact of climate change on monthly streamflow in Verde River Basin, located Grande Basin headwater. For this purpose, SWAT and VIC hydrological models were used to simulate under RCP4.5 RCP8.5 scenarios, obtained by Regional Climate Models Eta-HadGEM2-ES, Eta-CanESM2 Eta-MIROC5 baseline period (1961-2005) three time-slice (2011-2040, 2041-2070, 2071-2099) inputs. At end...
