The meaning of ISOTOPE is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. How to use isotope in
Lanzhousaurus magnidens, a large non-hadrosauriform iguanodontian dinosaur from the Lower Cretaceous Hekou Group of Gansu Province, China has the largest known herbivorous dinosaur teeth. Unlike its hadrosauriform relatives possessing tooth batteries of many small teeth, Lanzhousaurus utilized a small ...

Recently discovered elements are given names and symbols following an International Union of Pure and Applied Chemistry (IUPAC) recommendation until they are given proper names, for example, element 117 / Uus / ununseptium. For more information, see also convert/iupac. • To see the isotopes...
being a suitable tool for the reconstruction of the diet of past organisms. The proportion between the light and heavy isotopes of carbon and nitrogen in bone collagen, allows the identification of the origin of the proteins assimilated by the individual, since each large food group has its char...
Ratio of stable isotopes of carbon based on atomic weights 15N/14N: Ratio of stable isotopes of nitrogen based on atomic weights δ13C: Stable isotopes of carbon with an atomic weight of 13 δ15N: Stable isotopes of nitrogen with an atomic weight of 15 VDPB: Vienna Pee Dee Belemni...
Now, you need to introduce the name of your carbon content file. Later, you will get a message “The name of your Project is able to be processed”. Press y, if you want to continue the analysis, the process will be cancelled when you press n. When the analysis is successfully ...
This was expected because the enrichment of carbon isotopes per trophic level is low (i.e. ~1 ‰; DeNiro & Epstein 1978, Tieszen et al. 1983) compared to nitrogen isotopes (i.e. ~3 to 4 ‰; Minagawa & Wada 1984). Further, similar to Takai et al. (2000), we found a significant...
The Arctic environment harbors a complex mosaic of mercury (Hg) and carbon (C) reservoirs, some of which are rapidly destabilizing in response to climate warming. The sources of riverine Hg across the Mackenzie River basin (MRB) are uncertain, which leads to a poor understanding of potential ...
Figure 1: Location and elevation (meters above sea level) of tap water sample locations in China, sampling locations with names mentioned in context are presented as rhombuses in different colors and other general sample locations are presented as circles in royal blue. ...
