Known statistical techniques have been applied to the free amino acid composition of 107 samples from 10 different almond cultivars (Marcona, Desmayo-Largueta, Guara, Tuono, Ferragnes, Masbovera, Non Pareil, Titan, Texas, and Primorskyi) cultivated in seven different locations and growing conditions. It is concluded that free amino acid composition can constitute a basis for classifying and typifying these cultivars into five groups: (1) Marcona and Texas, (2) Ferragnes and Masbovera (and probably Primorskyi), (3) Tuono and Guara, (4) Non Pareil (and probably Titan), and (5) an isolated cultivar (Desmayo Largueta). As a result, an easy decision tree is proposed to discriminate the cultivar of an almond flour, as used in confectionery, if it consists of a single cultivar.
Abstract-The holographic storage of information is based on the interference of two waves: the reference wave and the object wave, the latter is generated by using a spatial light modulator, and in the case of applications of data storage this corresponds to a binary pattern of one and zeros. The interference pattern is recorded in a photosensitive medium (photopolymers, photographic emulsions, photorefractive, etc.), so that when illuminated by the reference wave the object wave is reproduced. In order to properly investigate the characteristics of the generated hologram it is necessary to adequately study the interaction of electromagnetic radiation with the recording medium. In this work we develop a completely vectorial formalism for solving the Helmholtz equation that allows investigation of electromagnetic dispersion in dielectric media in which the refractive index varies spatially. The method is based on the technique of Green's tensor and allows to correctly simulate the behavior of a volume hologram. This method is compared with the method of discrete dipoles and a formalism based on the first Born approximation to determine the intensity of light scattered by a volume hologram.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
