A new method for computing evolutionary distances between DNA sequences is proposed. Contrasting with classical methods, the underlying model does not assume that sequence base compositions (A, C, G, and T contents) are at equilibrium, thus allowing unequal base compositions among compared sequences. This makes the method more efficient than the usual ones in recovering phylogenetic trees from ...

[Purpose] To create a regression formula in order to estimate 1RM for knee extensors, based on the maximal isometric muscle strength measured using a hand-held dynamometer and data regarding the body composition. [Subjects and Methods] Measurement was performed in 21 healthy males in their twenties to thirties. Single regression analysis was performed, with measurement values representing 1RM a...

We introduce the concept of Expressive Performance Generated Composition where the initial specification for a composition comes from the details of an expressive performance. This expressive performance may have been of a previous piece or be specially produced for the composition. The expressive deviations in the performance are used to generate a meaningful interpretation of the performance ...

The electrophoretic mobilities in starch gels have been determined for eight enzymes in extracts of representative cultures of members of the family Enterobacteriaceae. These values were compared with each other and with those obtained from certain bacteria not in this family. The migrations of the eight enzymes were virtually identical for each of eight strains of Escherichia coli and for two ...

We outline a framework within which machine compositions may be evaluated objectively. In particular, the framework allows statements about those compositions to be refuted on the basis of empirical experimentation. We consider this to be fundamental if we wish to evaluate the degree to which our programs achieve their compositional aims. Furthermore, a review of the literature reveals that thi...

Weighted composition operators appear in the study of dynamical systems and also in characterizing isometries of some classes of Banach spaces. One of the most important generalizations of weighted composition operators, are generalized weighted composition operators which in special cases of their inducing functions give different types of well-known operators like: weighted composition operat...

This article discusses the geochemical and petrological evolution of São José do Campestre granite complex (SJCgr), last Neoarchean plutonic event so far described in massif NE Brazil. We report field, petrographic, zircon U-Pb dating, whole rock mineral chemistry for representative SJCgr samples. Laser ablation data indicate that emplacement took place at 2664 ± 13 Ma. The rocks comprising hav...

The Rio Jacaré Batholith (RJB; 617 ± 4 Ma) is inserted in the Poço Redondo Domain, Sergipano Orogenic System. This batholith formed by monzodiorite, quartz monzonite, and with abundant microgranular enclaves (MEs). MEs vary from black to light gray exhibit globular slightly elongated shapes clear-cut, crenulated, cuspate, or, more rarely, diffuse contacts. They correspond diorites, monzodiorite...

this study investigated the effect of season (wet and dry) on milk composition of the dromedary camel (camelus dromedarius). milk samples representing the wet and dry seasons were analyzed for total solids (ts), fat (f), solids-non-fat (snf), ash, crude protein (cp), nitrogen soluble at ph 4.6 (sn), mineral content (mc) and casein fraction (cnf). camel milk had higher (p<0.05) fat content in th...

introduction: during ramadan, adult muslims abstain from drinking and eating from sunrise to sunset. this religious practice influences individuals’ lifestyle factors such as eating behavior, meal schedule, and sleep pattern. these changes may affect endocrine and neuroendocrine circadian patterns, and consequently, cardiovascular indices. this study was performed to investigate the effects of ...
