Stable isotopes (Deuterium and Oxygen-18) have a broad application in many of water related sciences. Precipitation is the most important input to the water cycle which shows considrable spatial and temporal variability in its isotope content. To study the precipitation isotope content, 51 samples from August 2015 to July 2016 have been collected mainly on a monthly basis with few events based ...

Abstract Stable hydrogen and oxygen isotopes were used as natural tracers to identify spatial-temporal control on groundwater wells recharge basic physico-chemical parameters between lower Zab Tigris river South of AlShirqat city-Iraq. the search aimed study relationships in isotope compositions evaluate source recharge. Seven water samples analyzed for stable two periods, (dry wet), 2021. Ther...

Recently we prepared sulfated, low-molecular-weight lignins (LMWLs) to mimic the biological activities of heparin and heparan sulfate. Chemo-enzymatically prepared sulfated LMWLs represent a library of diverse non-sugar, aromatic molecules with structures radically different from the heparins, and have been found to potently inhibit thrombin and factor Xa. To assess their effect on the fibrinol...

Abstract. The stable oxygen (?18Oleaf) and hydrogen (?2Hleaf) isotopes of leaf water act as a bridge that connects the hydroclimate to plant-derived organic matter. However, it remains unclear whether source (i.e., twig water, soil precipitation) or meteorological parameters temperature, relative humidity, are dominant controls on ?18Oleaf ?2Hleaf. Here, we reported seasonal analysis ?2Hleaf to...

The International Organization for Standardization (ISO) published a new Technical Specification (TS), ISO/TS 20646-1 "Ergonomic procedures for the improvement of local muscular workloads (LMWL)--Part 1: Guidelines for reducing local muscular workloads" in 2004. However, little is known about whether the ISO/TS is really effective in taking action to improve the work conditions in real workplac...

This paper presents research related to the estimation of precipitation fraction in soil water a sloped vineyard at SUPREHILL Critical Zone Observatory (CZO) Zagreb, Croatia. Numerous investigations have shown that exploration hillslope soils can be very challenging due existence heterogeneity and different properties, as well anthropogenically induced processes, which affect infiltration flow....

Our current understanding of the intracellular thermodynamics and kinetics of Zn(ii) ions is largely based on the application of fluorescent sensor molecules, used to study and visualize the concentration, distribution and transport of Zn(ii) ions in real time. Such agents are designed for high selectivity for zinc in respect to other biological metal ions. However, the issue of their sensitivi...

Stable isotope studies on stable isotope ratios of hydrogen and oxygen in water within plants provide new information on water sources and water use patterns under natural conditions. In this study, the sources of water uptake for two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were determined at four different-aged revegetated sites (1956, 1964, 1981, and 1987) in t...

Moisture conditions are important ecological factors limiting plant growth in karst areas. In areas, because bedrock exposure and permeability significant soils dispersed—without spatial continuity—and shallow, the water storage required for uptake rock fissures as well shallow is very limited, therefore, an factor influencing growth. order to discover sources of used by plants zone ecosystem s...
