DeKay, J.F., 1830, On the remains of extinct reptiles of the genera Mosasaurus and Geosaurus found in the secondary formation of New Jersey; and on the occurrence of a substance recently named coprolite by Dr. Buckland, in the same locality: Annals of the Lyceum of Natural History of New...
It is obvious that research into the existence of biotic or abiotic “humification” processes only makes sense if humic substances are entities that do indeed exist naturally in soil. Thus the basis of research into the humification concept is the assumption that a humic substance such as a ...

By integrating these key events and the results of previous studies on replant disease formation, a new picture of the damaging mechanisms that cause replant disease stress emerged. Replant disease altered the metabolic balance of R. glutinosa, activated immune defence systems, increased levels of ...
For example, Lou’s group developed a new pyrolyzed PAN/selenium (pPAN/SeS2) composite as the cathode for Li-ion storage [15]. This nanocomposite effectively combined the benefits of pPAN/S and pPAN/Se while avoiding their disadvantages, resulting in excellent reaction kinetics, good chemical...
a connection of tributaries as a central depression may continually provide a point of weakness for the ice to rupture14. However, this does not explain why new troughs have not yet been observed to form within an existing radial araneiform in the present day. Whether the araneiforms of the...
Economic Substance Law Apart from the global effort for tax transparency, Cayman has enacted legislation that requires proof of economic substance in order for entities incorporated or registered there not be taxed. The International Tax Co-operation Economic Substance Act went into application from 1 ...
Thus, having a friend who is deviant or antisocial is likely to foster deviant or antisocial behaviour. For instance, one important determinant of adolescents’ use of alcohol and drugs is substance use by their close friends. Adolescents who have close friends who use alcohol or drugs are more...
Density is an indicator of where a substance will be. If it is heavier than air, it would move downward (e.g., in a lower level of a building), near the floor in a room, or in a lower compartment of a vehicle (e.g., a boat’s hull). If it is lighter than air, it will...
