Abstract: A method of manufacturing an antenna assembly includes additively manufacturing an element that is a monolithic structure and that includes (i) a ground plane including one or more aperture slots, (ii) a patch antenna above the ground plane, and (iii) a sacrificial support feature to support the patch antenna above the ground plane. The method further includes applying a dielectric material between the ground plane and the patch antenna. In an example, applying the dielectric material between the ground plane and the patch antenna includes providing a dielectric foam between the ground plane and the patch antenna, where the dielectric foam at least in part supports the patch antenna above the ground plane. The method further includes removing at least a section of the sacrificial support feature, such that any remnant of the support feature does not physically couple the ground plane to the patch antenna.

Abstract: Systems and methods of making carbon particles with thermal transfer gas. A method of making carbon particles may comprise heating a thermal transfer gas by Joule heating and contacting the thermal transfer gas with a reactive hydrocarbon feedstock gas to generate the carbon particles and hydrogen gas. A method of making carbon particles may comprise heating a thermal transfer gas with the aid of Joule heating and mixing the thermal transfer gas with a hydrocarbon feedstock gas to generate the carbon particles.

Abstract: A heating element for a vaporizer cartridge is provided. The vaporizer cartridge may include a reservoir containing vaporizable material and a wicking element in fluid communication with the reservoir. The heating element may include a heating portion, a cartridge contact, and a leg. The heating portion includes at least two tines spaced apart from one another. The cartridge contact may be in in electrical communication with a power source. The leg extends between the heating portion and the cartridge contact. The heating portion may be crimped around the wicking element such that the heating portion secures the wicking element to the heating element and contacts at least two surfaces of the wicking element.

Abstract: 1,4-Dihydropyridine derivatives which combine both calcium agonist and alpha.sub.1 -antagonist activity are useful in treating congestive heart failure. These derivatives are compounds having the formula: ##STR1## wherein Ar, R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are defined in the specification.

Abstract: Certain antihypertensive 1-substituted cyclic lactam-2-carboxylic acids and their derivatives are prepared by reacting an ester of the formula ##STR1## with a suitable derivative of the formula ##STR2##

Abstract: 1-Substituted cyclic lactam-2-carboxylic acids and their derivatives are useful as antihypertensive agents.

Abstract: A process for preparing nitroaromatic glycosides is described. The process comprises contacting an acetylated glycoside of maltotetraose, maltopentaose or maltohexaose with a phenol, nitrating the resulting product to place a NO.sub.2 group on the aromatic moiety and deacetylating the nitrated product. The nitroaromatic glycosides are useful as standard substrates for the assay of .alpha.-amylase.

Abstract: Nitroaromatic derivatives of glycosides such as maltotetraose, maltopentaose and maltohexaose are described. These compounds are useful as standard substrates for the assay of .alpha.-amylase either manually or automatically on suitable instruments.

Abstract: Substituted pyrazole compounds have been found to be effective plant growth regulants. Exemplary of the effective compounds are 3-(2-carboxyphenyl)-5-phenyl-pyrazole, its 2-ethanolamine salt, and 3-(2-carboxy-1-cyclohexen-1-yl)-5-phenylpyrazole.
