We report on the variation of a methyl tunnel splitting with pressure. The measurements are the first studies of thepressure variation of a methyl tunnel splitting using low-field, of order 80 gauss, dipole-dipole driven NMR spectroscopywith rapid field-cycling. Pressures up to 1.8kbar were applied with an operating temperature of 4.2K. In addition protonspin-lattice relaxation time...

In this data article, we presented the electrochemical data of the working electrode made of Co3O4 semi-transparent film. Electrochemically stable, porous nature of Kirkendall-diffusion grown Co3O4 films were applied to generate hydrogen from the seawater splitting (Patel et al., 2017) [1]. The data presented in this article includes the photograph of prepared samples, polarization curves for w...

The current status of the determination of corrections to the hyperfine splitting of the ground state in hydrogen is considered. Improved calculations are provided taking into account the most recent value for the proton charge radius. Comparing experimental data with predictions for the hyperfine splitting, the Zemach radius of the proton is deduced to be 1.045(16) fm. Employing exponential pa...

The effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated. Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass a...

In order to provide more watermarks and to minimize the distortion of the watermarked image, a novel technique using the combinational spatial and frequency domains is presented in this paper. The splitting of the watermark image into two parts, respectively, for spatial and frequency insertion relies on the user’s preference and data importance. Experimental results provide the comparisons whe...

The deuteron, N N analyzing powers A y , and the singlet scattering length show great sensitivity to the πN N coupling constant g π. While the pp A y data favor g 2 π /4π ≤ 13.6, the np A y data and the deuteron quadrupole moment imply g 2 π /4π ≥ 14.0. The two diverging values could be reconciled by the assumption of (substantial) charge-splitting of g π. However, the established theoretical e...

This paper proposes a triangulation method for a digitized surface whose points are located on a regular lattice. The method relies on an iterative and adaptive splitting of triangular faces of an initial polyhedral surface. Assuming a bijection between the digitized surface and its approximation, a partition of the data base is performed. The method allows the measurement of the local quality ...
