Machine learning (ML) is transforming all areas of science. The complex and time-consuming calculations in molecular simulations are particularly suitable for an ML revolution and have already been profoundly affected by the application of existing ML ...Read More
It is suggested that, in spite of its well–known limitations (/), the Kozeny–Carman equation can provide a reasonably satisfactory description of the major features of fluid flow through textile materials, provided that the fluid flow is streamline and that the permeability of the yarns themselves is taken into accoun…

The Laplace equation for the pressure drop across curved liquid-gas interfaces is applied to the solution of the profile of a static liquid meniscus on the outside of a wire of circular cross-section. The resulting differential equation is integrated numerically, an operation complicated by the existence of boundary c…
The piezoelectric modulus d 33 , electromechanical coupling factor k 33 and elastic compliance coefficients s 33 D , s 33 E of SbSI have been determined by measuring the resonant and anti-resonant frequencies on single crystals of 3 mm in length and 0.7×0.7 mm 2 in cross section. The d 33 has been found to show the hi…
The crystal structure of erbium titanate, Er 2 Ti 2 O 7 , has been shown by X-ray and neutron powder diffraction to be of the cubic pyrochlore type, with a o = 10.0762 ± 6 Å. Least-squares isotropic refinement based on resolved single reflections gave x(O 2 ) = 0.4200 ± 10 and R = 2.25%. Ionic and neutral X-ray scatte…
1. The effect of ultraviolet irradiation on acid-soluble and neutral-salt-soluble calf-skin collagen was studied by chromatography, gel filtration, amino acid analysis and sedimentation of the sub-units, and the reaction kinetics of degradation were obtained from viscosity and optical rotation measurements. 2. It was…

Paramagnetic alpha-MnMoO4, the stable phase at STP, is monoclinic with lattice constants a=10.469±0.005, b=9.516±0.005, c=7.143±0.005 Å, and β=106°17′±6′, and space group C2/m. The crystal structure has been solved and refined by a combination of three-dimensional Patterson and Fourier series and by the method of leas…
ESR studies of three paramagnetic tetraphenylporphine chelates: vanadyl, cobalt, and copper reveal distorted crystal-field surroundings which are more pronounced in the cobalt derivative. The spin-Hamiltonian parameters and the 3d energy levels of the cobalt derivative are greatly influenced by axial distortions. The…
The copepod Lernaea sp. was found parasitizing 14 of 28 species of fishes collected from the Des Moines River, Iowa. Forty-nine diatom taxa from 15 genera were identified in a collection prepared by digestion of 50 algal-covered copepods. No diatoms were observed on copepods collected from the lower zone of the river.…

The calculation performed in [1] is extended to the case of impurity ferromagnetism and of an external magnetic field. It is shown that depending on the ratio between ${T}_{\mathrm{max}}$ (see [1]), ${T}_{c}$ (Curie temperature) and $\mathrm{\ensuremath{\mu}}H$ various kinds of non-monotonic behaviour of the resistanc…
Abstract Dilatometrically determined glass transition temperatures and thermal expansion coefficients of 47 different polymers, most of them acrylics, are reported. The experimental values are discussed in terms of the effect of side‐chain flexibility, bulkiness, and polarity on the glass transition temperature and ar…
Abstract : The crystal structure of yttrium orthoferrite has been determined from full three-dimensional counter data and refined in the space group Pbnm by least squares to an accuracy of about .001 and .01A in positional parameters of Y(3+) and O(2-) respectively. Parameters are compared with those of GdFeO3, derive…
