soil in which they were found but are the remains of animals living in the sea on whose bed the soil (sediment) was deposited. The latter paper is a summary of a projected further work which unfortunately never appeared. It is the Prodromus that contained the first statement of the Law of Superposition; and much more. 'If, in a certain stratum, we find great abundance of rushes, grass, pine con...

An overview is presented on the program to study the nucleon structure at the 12 GeV JLab upgrade using the CLAS12 detector. The focus is on deeply virtual exclusive processes to access the generalized parton distributions, semi-inclusive processes to study transverse momentum dependent distribution functions and inclusive spin structure functions, and resonance transition form factors at high ...

The potential for efficient production of hydrogen-rich gas from hydrocarbon fuels using thermal plasmas has been investigated both analytically and experimentally. Thermodynamic analysis shows that the most efficient production of hydrogen from hydrocarbons can be achieved by partial oxidation (lambda = 0.25); at optimal conditions, the availability of the output fuel mixture is 83 percent of ...

Objectives: Success of regenerative dental procedures highly depends on their acceptance by the clinicians; yet, little is known about dental residents’ attitudes regarding this new technology. The purpose of this study was to assess the knowledge and attitude of post-graduate dental students towards stem cells and regenerative dentistry as part of future dental treatments. Methods: This cross...
