We propose a modified phenomenological equation for heat and impurity fluxes in solids by analogy with the Cattaneo-Vernotte concept. It leads to the second-order elliptical equations describing the evolution of temperature and impurity profiles with finite rate of propagation. The comparison of transfer peculiarities in the framework of parabolic and elliptic equations is discussed.

Proton nuclear magnetic resonance (1H NMR) is the application of nuclear magnetic resonance in NMR spectroscopy with respect to 1H within the molecules of a substance, in order to determine the structure of its molecules. The work focused on determining the 1H NMR spectrum of the molecule here called Xalapa, in homage of the city of Xalapa, the capital city of the Mexican state of Veracruz and the name of the surrounding municipality. The 1H NMR spectrum was obtained via computational methods ab initio Restricted Hartree-Fock. Optimization of molecular structure via UFF, followed by PM3, RHF/EPR-II and RHF/STO-6G, thus obtaining a stable structure, in STP, NMR via the GIAO(Gauge-Independent Atomic Orbital) method. The IUPAC name of the molecule was obtained, whose composition is C: 81.7%; H: 7.1%; N: 3.4%; O: 7.8%, formula weight: 411.53536 g, and molecular formula: C28H29NO2. Limitations our study has so far been limited to computational simulation via quantum mechanics (QM) an applied theory. Our results and calculations are compatible with the theory of QM, but their physical experimental verification depends on experimental data that should be laboratory for experimental biochemical.

We study the Swahili-English Dictionary by Charles W. Rechenbach. We draw the natural logarithm of the number of the words, normalised, starting with a letter vs the natural logarithm of the rank of the letter, normalised. We find that the dictionary is classified by BP(4,βH=0.04). β is 1/(k_B T) where, T is temperature and k_B is the Boltzmann constant. BP(4,βH=0.04) is the magnetisation curve for the Bethe-Peierls approximation of the Isingmodel with four nearest neighbours in the presence of little external magnetic field, H, such that βH is equal to 0.04. Moreover, the words of the dictionary go over to the Onsager solution on successive normalisations.

In our previously published work, we have reported colossal magnetoresistance, Andreev oscillations, ferromagnetism, and granular superconductivity in oxygen-implanted carbon fibers, graphite foils, and highly oriented pyrolytic graphite (HOPG). In this follow-up research, more results on these oxygen-implanted graphite samples are presented. We show results from transport measurements on oxygen-implanted diamond-like carbon thin coatings, amorphous carbon films, and HOPG. Significantly, a three-order magnitude drop in the electrical resistance of the oxygen-implanted diamond-like carbon films is observed at the 50 K temperature that we have previously reported for the transition to the superconducting state. Below 50 K, the films' resistance oscillates between the high and low resistance states, less when the sample is under a transverse magnetic field. This metastability between the insulating and superconducting-like states possibly reflects the evolution of the amplitude for the superconducting order parameter also known as the longitudinal Higgs mode. Transitions to low resistance state and metastability are also observed for amorphous carbon films. Finally, the HOPG samples’ resistance have a thermally activated term that can be understood on the basis of the Langer–Ambegaokar–McCumber–Halperin model applied to narrow SC channels in which thermal fluctuations can cause phase slips. We also find that in oxygen-implanted carbon materials, the electron charge and spin correlations do not compete and their interplay rather facilitates the emergence of high-temperature superconductivity, and thus, additional unexpected effects like Heisenberg spin waves and magneto-structural transitions are observed.

A new detailed theory is developed for how isotopes of nonzero nuclear magnetic moments (NMMs) provide nuclear pressures for hidden stimulations for driving transportations locally for agitations; for transformations for chemical, catalytic and enzymatic activities; for thermodynamics for novel energetic, equilibrium and entropic redistributions; and for transmutations reversibly and fractionally. Such are basis for normal life activities by positive NMMs of 1H, 14N and 31P and other less abundant NMMs from stable isotopes of other elements as in vital minerals: 25Mg, 63Cu, 65Cu, 64Zn, 66Zn, 67Zn, 68Zn, 57Fe, 43Ca, 23Na, 55Mn, 95Mo, 97Mo, 53Cr, 77Se, 19F, 39K, 40K and 41K and others. Where bolds have negative NMMs, boldless have positive NMMs, and italics have 100% or nearly compositional 100% relative abundances. On the basis of such more details are added for aging of living organisms as isotopes redistribute in biomolecules for clumping into specific chemical bonds on nanoscales and possibly gradual to cataclysmic enrichments in nano-domains of uncommon isotopes of 13C, 15N, 17O, 25Mg, and 33S for altering the nuclear pressures for dissipative cycles of 1H, 14N, and 31P for causing aging and disease. The passage of these isotopes are considered during cellular replications. The catalytic prominent role of 17O for aging and cancer is demonstrated. The basis for accelerated enrichment by external electromagnetic waves and static magnetic fields and electric fields is developed. The stronger property shift by greater altering electrons is reasoned by multiple cataclysmic fractional, reversible fissing and fusing. Distinct effects of nanodomains of all positive NMMs, all negative NMMs, homogeneous mix of positive and negative NMMs, and heterogeneous mix of positive and negative NMMs are developed. The contributions of these different stable isotopes by their NMMs to normal logistics and cancer logistics are developed. The differing impacts of these stable isotopes are reasoned based on their electronic states and the change in NMMs by replacing common primordial isotopes by uncommon nonprimordial isotopes.

We find that the Essential Dutch Dictionary by G. Quist and D. Strik is classified by a magnetisation curve of a Spin-Glass in the presence of little external magnetic field.
