Nuclear magnetic resonance (NMR) logging provides a new means of estimating the hydraulic conductivity (K) of unconsolidated aquifers. The estimation of K from the measured NMR parameters can be performed using the Schlumberger-Doll Research (SDR) equation, which is based on the Kozeny-Carman equation and initially developed for obtaining permeability from NMR logging in petroleum reservoirs. T...

A new equation for microbial growth has been proposed and its implications discussed. The proposed equation has a distinct advantage over B e r t a l a n f f y ' s in being an explicit relationship between growth parameter and time. Attempt has been made to read the proposed equation in the light of H i n s h e 1 w o o d's auto-synthetic model. The constants occurring in the proposed equation h...

The spinor Bethe-Salpeter equation describing bound states of a fermion-antifermion pair with massless-boson exchange reduces to a single (uncoupled) partial differential equation for special combinations of the fermion-boson couplings. For spinless bound states with positive or negative parity this equation is a generalization to nonvanishing bound-state masses of the equations studied by Kumm...

This paper investigates the viability and stability of anisotropic compact stars in framework f(R,T2) theory (R is Ricci scalar T2=TτυTτυ). In this perspective, we use Finch–Skea symmetry consider different models to examine physical characteristics stars. We match interior spacetime with exterior region find values unknown constants. Further, analyze behavior several quantities such as effecti...

The origin of the concept of a molecular complex between oxygen and hemoglobin can be traced to Stokes, a century and a half ago. Subsequently, physicochemical concepts of equilibria provided a path to quantitative formulations of these ligand-receptor interactions. Then, it took a quarter of a century before a proper format was prepared in terms of four stoichiometric equilibria and their asso...

We report an experimental determination of the state-to-state rate constants of N2 in the vibrational ground state as a function of temperature, in the range 3,T,16 K. These rate constants were obtained by inversion of the master equation in a procedure not resorting to any particular fitting law. The coefficients of the master equation were obtained experimentally on the basis of Raman spectro...
