چکیده

The cycles of the water isotopic species (HDO and H2 0) have been incorporated in three atmospheric General Circulation Models (GCMs) with the main objective of predicting the distribution of water stable isotopes in precipitation, The performances of those models are examined for present-day climate through a comparison with existing data available from the IAEA/WMO network established in 1961 and from other sources. Deuterium et oxygène-18 dans les précipitations contemporaines: données et modélisation Résumé Les cycles des formes isotopiques de l'eau (HDO et H2 0) ont été désormais incorporés dans trois modèles de circulation générale de l'atmosphère (MCG) avec pour objectif principal de prédire la répartition de ces isotopes stables dans les précipitations. Dans cet article de synthèse, nous examinons les performances de ces modèles pour le climat actuel à travers une comparaison avec les données disponibles grâce au réseau AIEA/OMM établi en 1961 et à d'autres sources.

Eocene and Oligocene variations in deuterium isotopes across the Sierra Nevada and Miocene–Quaternary differences in deuterium and oxygen isotopes between the Great Valley of California and the Basin and Range

Although geomorphic observations suggest that the Sierra Nevada has tilted so that the crest has risen 1–2 km since late Miocene time, deuterium and oxygen-18 isotope concentrations in Cenozoic geologic materials decrease eastward across California and Nevada similarly to those in modern, orographically induced precipitation, as if little change in Sierra Nevadan elevations has occurred since E...

Pre-Clinical and Clinical Data Confirm the Anticancer Effect of Deuterium Depletion

The two stable isotopes of hydrogen, protium (1H) and deuterium (2H) differ in their physicochemical nature. Deuterium-depleted water (DDW) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted MDA-MB-231, MCF-7 human breast adenocarcinomas and PC-3 human prostate tumors in vivo. The apoptosis-triggering effect of DDW was demonstrat...

Hydrochemistry and stable isotopes study of the precipitation at Haraz Basin, north of Iran

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 ...

Comparison of physical, chemical and hydrogeological characteristics of karst springs in the western and eastern regions of Ilam province, Iran

Karst springs in the western and eastern regions of Ilam province have different physical and chemical properties. The springs of  the western regions, are sulfuric and thermal with high salinity; while, springs in the eastern regions, are fresh and cold. Geological, hydrogeological, hydrogeochemical and isotope studies were performed to compare and determine the factors affecting the physical ...

Artificial intelligence-based approaches for multi-station modelling of dissolve oxygen in river

ABSTRACT: In this study, adaptive neuro-fuzzy inference system, and feed forward neural network as two artificial intelligence-based models along with conventional multiple linear regression model were used to predict the multi-station modelling of dissolve oxygen concentration at the downstream of Mathura City in India. The data used are dissolved oxygen, pH, biological oxygen demand and water...
