The scope of solid-state transitions, from melting temperatures down to 4.2 K, is described for six systems: K x VF 3 , Rb x VF 3 , Cs x VF 3 , K x CrF 3 , Rb x CrF 3 , and Cs x CrF 3 (for x = 0.0 to 1.0). Connections are drawn between the compounds’ composit…

The El Ni n o Index, defined as 4 intensities (very strong, strong, moderate, weak) in Oceanic Niño Index (ONI), was positively correlated with the average sunspot number at each intensity. The La Niña Index, defined as 3 intensities (strong, modera…

Glutamate, the most abundant excitatory neurotransmitter in the nervous system, can induce biophotonic activity and transmission in mouse brain slices. As a signaling molecule, aspartate is not considered to be an independent neurotransmitter during the long…

If Goldbach’s conjecture is true, then for each prime number p there is at least one pair of primes symmetric with respect to p and whose sum is 2 p . In the multiplicative number theory, covering the positive integers with primes, during the prime factorizat…

This article describes the use of the first order system transfer function for learning and memory studies involving consumption of marijuana and other plant based products. We provide detailed instructions on how the model can be used to analyze the performa…

The problems of unattainable infinity and infinitesimal are discussed. Limitations connected with the absolute zero of temperature and the maximal velocity are considered, as well as the consequences of these limitations. A geometric approach is proposed as a…

A preliminary attempt is made to address Stommel’s suggestion that the established offshore shear in the Gulf Stream’s surface velocity is large (up to 0.5 f , where f is the Coriolis parameter) and that this needs to be understood better. Using Bernoulli’s l…

Surface roughness is one of the most important evaluation indexes in machine cutting. In order to analyze how the tool path affects the roughness of the surface after milling, series of simulations are implemented in MasterCAM. We set up the same processing c…
