Drought as a natural but temporary imbalance of water availability is the interaction between natural environment and human life resulting in diminished water resources availability and reduced carrying capacity of the ecosystems. Drought indices are essential elements for an efficient drought monitoring system. These indices make the transforming information of climatic anomalies easier and al...

The present study investigated the volatile compound, physicochemical, and antioxidant properties of beany flavor-removed soy protein isolate (SPI) hydrolyzates produced by combined high temperature pre-treatment and enzymatic hydrolysis. Without remarkable changes in amino acid composition, reductions of residual lipoxygenase activity and beany flavor-causing volatile compounds such as hexanol...

Drought is a complex phenomenon which can be characterised mainly by its severity, duration and areal extent. Among these three dimensions, drought severity is the key factor which can be used for drought analysis. Drought indices are typically used to assess drought severity in a meaningful way. DrinC (Drought Indices Calculator) is a software package which was developed for providing a simple...

INTRODUCTION Obstructive sleep apnea (OSA) is a well-recognized risk factor of cardiovascular disorders and is related to metabolic syndrome. The aim of this study was to evaluate the effect of BMI and AHI/RDI on metabolic disturbances in patients suspected of OSA. MATERIAL AND METHODS Ninety-nine patients referred with suspected OSA underwent standard polysomnography or limited sleep study. ...

BACKGROUND Protein needs for athletes are likely higher than those for the general population. However, athletes may perceive their protein needs to be excessively high. The purpose of this research was to compare collegiate athletes' perceived protein needs and measured protein intake to the recommended protein intake (RDI) for healthy adults (i.e. 0.8 g/kg/d) and to the maximum beneficial lev...

This manuscript aims to develop a new multivariate composite index for monitoring agricultural drought. To achieve this, the AVHRR, VIIRS, CHIRPS data series over period of 40 years, rainfall and crop yield as references were used. Variables include parameters vegetative stress (SVCI, PV, SMN), water (PCI, RDI, NRDI), heat (SMT, TCI, STCI), variable related environmental conditions was calculat...
