El objetivo del presente estudio fue identificar el efecto agudo de una sesión Educación Física orientada a la meditación en los niveles estrés escolares 8 12 años., Participaron 34 chilenos, cuales fueron divididos manera aleatoria un grupo experimental (n18) y control (n16). Durante clase realizó mindfulness con duración 15 minutos, mientras hizo encuesta hábitos saludables conducta sedentari...

Whether oxidative deamination is the favored initial step in the catabolism of histidine, as may be the case with many of the amino acids, is open to question. The supporting evidence of Krebs (1) is less striking with r,-histidine than with most other natural amino acids. Kidney slices yielded somewhat more ammonia in the presence of histidine and oxygen than in the absence of either, and live...

via time slices which involve only nine information symbols, viz. u t ; u t01 ; 1 1 1 ; u t08. From the time slices for the phases that are multiples of 4 it follows that information symbol u t08 does not contribute to the corresponding output. This information symbol does not contribute to the outputs in the following time instants either; hence, we do not have to store it! Thus the Kötter–Var...

The state of stress in the Eastern California Shear Zone (ECSZ) changed significantly because of the occurrence of the 1992 Mw 6.1 Joshua Tree and the Mw 7.3 Landers earthquakes. To quantify this change, focal mechanisms from the 1975 Galway Lake sequence, the 1979 Homestead Valley sequence, background seismicity from 1981 to 1991, and the 1992 Landers sequence are inverted for the state of str...

Lipid biomarker analysis has proven valuable in testing the hypothesis that attributes of the extant microbiota can directly reflect the occurrence of contaminant biodegradation. Two past research efforts have demonstrated this utility and are described here. A 4.5 m vertical core was obtained from a diesel fuel oil contamination plume. Core material was assayed for total petroleum hydrocarbons...

Experiments in tivo have demonstrated that animals are able to invert certain n-amino acids to their natural forms (l-4). This inversion has been repeatedly confirmed in studies with different species of animals by their ability to utilize the D enantiomorphs for t-he purposes of growth or maintenance of nitrogen equilibrium. In the case of the rat, the D isomers of histidine (5, 6), methionine...

Genetic Algorithm Combining Operation Tree (GAOT) was constructed to estimate the slump flow of high-performance concrete (HPC) by using seven concrete ingredients. HPC is a highly complex material; because modeling its behavior is extremely difficult, robust optimization techniques are required. GAOT is a type of evolutionary algorithm that simultaneously optimizes functions and their associat...
