In developing countries, the study of intellectual disability has enormous knowledge gaps, especially in the areas of intervention, utilization of services and legislation. This article provides information not only for aiding in the potential development of sexuality in individuals with…

Brachypelma vagas belongs to a genus of tarantulas protected against illegal trading. Its distribution range is in Mesoamerica. The spiderlings remain together in the maternal burrow after hatching and after several weeks, they disperse forming a column of about hundred…

Ethnoarchaeological research at the site of Cuentepec, Mexico includes experimental pottery dating in which social knowledge is obtained from archaeometric techniques. At Cuentepec, open kilns are used for firing pottery. Samples from volcanic rocks in the kilns were taken to…

Knowledge of soil petrophysical parameters is very useful for agricultural and environmental impact analysis. Therefore, it is important to develop techniques and methodologies to help obtain soil petrophysical maps both quickly and inexpensively. This paper shows two techniques for estimating…

Measurements of multiphoton ionization and dissociation of acetone are reported in the wavelength range 490.0-510.0 nm at 1 nm intervals. To our knowledge there are no available results of (3+1) REMPI on acetone in this region. The experiments were performed…

Secure multimedia communication presents new challenges that are difficult to handle using by currently adopted encryption schemes (RSA-Rivest-Shamir-Adelman, AES-Advanced Encryption Standard, and IDEA-International Data Encryption algorithm) (28). It requires the processing of huge amounts of information at speeds ranging from…

The radiofrequency coil is a crucial component of the magnetic resonance imaging scanners, so that a solid knowledge on the design and physical characteristics is important for those interested in its development. A birdcage coil with a 10 cm radius…

In this work we present a theoretical study of the spontaneous capillary flow of a viscous liquid, developed in the gap between a couple of parallel corrugated plates (corrugated Hele-Shaw cell). The periodical corrugation of the interior walls of the…

We give an elementary proof of the Liouville theorem, which allows us to obtain n constants of motion in addition to n given constants of motion in involution, for a mechanical system with n degrees of freedom, and we give…

The problem of nuclear track overlapping is addressed assuming the stochastic character of charged particle registry and the fact that even monoenergetic beam perpendicularly impacting on detector surface will show a distribution for track radius values. Asymmetric distributions of overlapping…
