The Shitoukengde Ni-Cu deposit, located in the Eastern Kunlun Orogen, comprises three mafic–ultramafic complexes, with the No. I complex hosting six Ni-Cu orebodies found recently. The deposit is host...
Using stable isotopes to assess mineral absorption and utilization by children
Calcium absorption iron absorption mineral requirements
2016/6/2
Adequate mineral intake is a crucial part of a
healthy diet for children—it supports appropriate growth and
development and provides protection against childhood conditions
like anemia and helps to...
Molybdenum absorption and utilization in humans from soy and kale intrinsically labeled with stable isotopes of molybdenum
Molybdenum absorption utilization
2016/5/31
Stable-isotope studies of molybdenum metabolism
have been conducted in which molybdenum was added to
the diet and was assumed to be absorbed and utilized similarly to
the molybdenum in foods.
Pre-Whaling Genetic Diversity and Population Ecology in Eastern Pacific Gray Whales: Insights from Ancient DNA and Stable Isotopes
Population Ecology Pre-Whaling Genetic Diversity
2015/12/11
Commercial whaling decimated many whale populations, including the eastern Pacific gray whale, but little is known about
how population dynamics or ecology differed prior to these removals. Of partic...

ocean model Community Earth System Model
2015/8/11
Carbon isotopes in the ocean are frequently used
as paleoclimate proxies and as present-day geochemical
ocean tracers. In order to allow a more direct comparison of
climate model results with this ...
Following the highly publicized 1998 E1 Niño event, interest in how climatic events in the tropics affects global climate has grown. However, an understanding of the long-term natural variability...
GEOTRACES—A Global Study of the Marine Biogeochemical Cycles of Trace Elements and Their Isotopes
Marine Biogeochemical Cycles Trace Elements Their Isotopes
2015/7/28
Since the late 1990s there has been a growing impetus for a comprehensive global study of the marine biogeochemical cycles of trace elements and their isotopes (TEIs). This has led to the development ...

The hillslope rainfall-outflow interactions, groundwater fluxes, and hydrological balance were examined in the small mountainous headwater catchment Uhlířská, the jizera Mountains, the Czech Repu...
Altitudinal gradients of natural abundance of stable isotopes of nitrogen and carbon in the needles and soil of a pine forest in Nepal
pine forest Nepal stable isotopes
2015/1/29
This paper deals with natural abundance of 15N and 13C in the soil and needles of the pine forest (Pinus roxburghii, Sargent) along an altitudinal gradient. The study area lies in the elevation range ...
Semi-Lagrangian transport of oxygen isotopes in polythermal ice sheets: implementation and first results
Semi-Lagrangian transport oxygen isotopes polythermal ice sheets implementation first results
2014/12/19
Modelling the evolution of the Earth system on long timescales requires the knowledge and understanding of driving mechanisms, such as the hydrological cycle. This is dominant in all components of the...
