A theory of the birefringence produced in a substance perpendicular to a strong magnetic field (the Cotton-Mouton effect) is presented. Allowance is made for electrical anisotropy induced directly by the magnetic field, an effect which can occur even for isotropic molecules. The effect of molecular interaction on meas…
The present work was undertaken with the purpose of considering why and how reaction takes place in an ultrasonic field, rather than studying the chemical kinetics of such reactions. Experimental evidence is presented which supports the conclusions that chemical processes brought about by ultrasonics require cavitatio…

If a textile yarn segment, clamped at each end, is impacted transversely at the mid point, the stress-strain curve for this yarn can be obtained from measurements on a high speed photographic record of the yarn's motion. This paper describes the apparatus and procedure used. Stress-strain curves for high rates of stra…
The influence of differences in the Al / Si -distribution of feldspars on the infrared absorption in the region of 7 to 16 μ is shown. Relations between the low- and high-temperature modifications of feldspars in view of their absorption spectrae are discussed. The value of infrared absorption measurements for the dis…
By using special acoustical and optical arrangements, vortex motions are discovered in the vicinity of small vibrating sources in liquids. Of particular importance is the vigorous eddying that typically takes place near a vibrating gas bubble when it rests on a boundary. This bubble-associated streaming has been obser…
The movement of liquid water in fiber assemblies such as yarns and fabrics is examined in terms of a theory of water transport based on a capillary penetration mechanism. Yarn construction features, such as twist, diameter, crimp, and fiber denier, are shown to be related to the rate of water transport in such fiber a…

Silicon carbide was hot‐pressed to uniform densities of the order of 98% of the theoretical density, with slight additions of aluminum and iron aiding in this densification. Other elements having some effect were lithium, calcium, chromium, zirconium, and boron. This dense silicon carbide had very high strength at hig…
Abstract The preferential orientation of the carbon planes in blocks of graphite prepared by extrusion or pressing is described in terms of an orientation function and it is shown how this varies with the particle size of the starting materials. An ‘anisotropy factor’ is defined as a useful index of the material. A di…
A modified Landau-Lifshitz equation is solved for a single-domain sphere and an infinitely-wide thin single-domain sheet of ferromagnetic material neglecting anisotropy. The external magnetic field is switched from one direction to its opposite instantaneously at the initial time and the behavior of the magnetization…

Por vía teórica también experimentalmente se llega a la conclusión de que, en general, es conveniente elevar la cifra máxima SO3 mantenida en la actualidad en la mayor parte de las normas para cemento. Esta medida es particularmente beneficiosa en el aspecto de la retracción.
