TL;DR: Isomeric cross section ratios were measured for (n, 2n) reactions induced by 14.7 MeV neutrons in In and Sb isotopes to compare with the theoretical calculations performed with the Huizenga and Wandenbosch method.

TL;DR: It has been shown that lymphoid cells from subjects immunized against bacteria are able to immobilize the specific antigen on their surface, and gamma globulins on the cell membrane.
Abstract: IT is generally agreed that at least some lymphocytes carry immunoglobulins with antibody properties on their surface. It is still a matter of discussion whether or not these immunoglobulins are synthesized by the cell itself, and whether their presence is related to lymphocyte immunocompetence. It has been shown, however, that lymphoid cells from subjects immunized against bacteria are able to immobilize the specific antigen on their surface. Nevertheless, because of technical difficulties, it is very hard to demonstrate directly the presence of gamma globulins on the cell membrane; even very sensitive methods, such as immunonuorescence, have given variable and inconsistent results1,2.

TL;DR: In this paper, an investigation was undertaken on the influence of the drill point geometry on the cutting forces, and the results were compared with those of cutting tests made with these drill points.
Abstract: SUMMARY An investigation was undertaken on the influence of the drill point geometry on the cutting forces. A number of measurements were performed on a lot of nominally similar twist drills, and the results were compared with those of cutting tests made with these drills. The effects of several dimensional parameters were thus assessed, and the results were discussed in the light of an approximate analysis of the drill point geometry.

Abstract: In this letter, the reciprocity relationship of electromagnetic theory is established for the bianisotropic media. The result is applied to the particular case of a uniformly moving medium, even when it has anisotropic properties in its rest frame.

TL;DR: In this article, the scattering of slow neutrons from spherical-top molecules of point groups was analyzed and discussed, taking into account the rotation-vibration interaction, and explicit extensive expressions for the intermediate scattering function and the partial differential cross section were derived.
Abstract: The scattering of slow neutrons from spherical-top molecules of point group ${T}_{d}$ is analyzed and discussed, taking into account the rotation-vibration interaction. After the introduction of the general formulation for the partial differential cross section, the Hamiltonian of the spherical-top molecule is discussed, and the contribution of the rotation-vibration interaction is considered in detail. By using group-theoretical methods, the rotational-vibrational wave function, and then the total wave function, are obtained. Finally, explicit extensive expressions for the intermediate scattering function and the partial differential cross section are derived.

TL;DR: In this paper, a variant of the well known method of interpolation in the network sense due to Smilen is presented; with this variant, a saving of reactive elements may be obtained in the transformerless case.

TL;DR: In this article, the behavior of a curved slits chopper-monochromator has been examined and the path of a neutron passing through it has been determined without any restriction on the incidence angle and on the angle of rotation of the chopper.

TL;DR: The described procedures represent an improvement over the preceding solutions for the following reasons: they are systematic and consist of simple algebraic operations, and can be usefully employed for synthesizing incompletely specified functions.
Abstract: The paper contains some new contributions to the problem of synthesizing an assigned function with three-input majority gates. The obtained networks have a tree structure and can be calculated using two different types of decompositions.

Journal ArticleDOI
TL;DR: In this paper, an elastic theory for shells generated by translation of an arbitrary profile Λ along an arc of finite rise and large chord, as compared with the dimensions of Λ, is developed on a three-dimensional basis by the method of parametric expansions.

Journal ArticleDOI
TL;DR: In this paper, the authors deal with the behavior of an axially loaded viscoelastic structure at one degree of freedom in the large deformation range; the stress-strain relation assumed is linearly visco-elastic, with the kernel at non invariant memory, typical of concrete.
