Augustine Spanish Floridais the first known and recorded Christian marriage anywhere in what is now the continental United States. The settlers and the slaves who had not escaped returned to Haitiwhence they had come. The status of indentured servants in early Virginia and Maryland was similar to slavery. Servants could be bought, sold, or leased and they could be physically beaten for disobedience or running away.
The small-signal speed of sound in humid air is calculated from a model which includes the real-gas effects from the equation of state for humid air and the vibrational dispersion due to N2, O2, and CO2 relaxation.
Other atmospheric effects such as dispersion due to viscothermal and rotational relaxation, heat radiation, propagation along the air-ground boundary, the density gradient, turbulance, aerosols and fogs are considered and found to be unimportant for frequencies between 1Hz and 5 HHz at one atmosphere.
The uncertainty African studies dubois vs washington predicting the sound speed varies between 0. Experimental results in humid air at 20C and 30C are in excellent agreement with the model.
For the propagation frequency of 20 Hz, it is found that the presently used sound-ranging formula, c - A correction to the "sonic" temperature determination is suggested with results in deviations of less than 0. For over a century, various neuroanatomical measures have been employed as assays of cognitive ability in comparative studies.
Nevertheless, it is still unclear whether these measures actually correspond to cognitive ability.
A recent meta-analysis of cognitive performance of a broad set of primate species has made it possible to provide a quantitative estimate of general cognitive ability across primates. We find that this estimate is not strongly correlated with neuroanatomical measures that statistically control for a possible effect of body size, such as encephalization quotient or brain size residuals.
Instead, absolute brain size measures were the best predictors of primate cognitive ability. Moreover, there was no indication that neocortex-based measures were superior to measures based on the whole brain.
The results of previous comparative studies on the evolution of intelligence must be reviewed with this conclusion in mind. Originally published in This study investigated the effect of different breathing rates on cardiac autonomic tone and blood pressure control.
The influence of nose and mouth-only breathing was also assessed. After obtaining ethical approval and informed consent, sixteen healthy subjects 8 males, 8 females, aged Cardiac autonomic tone was assessed by heart rate variability HRV in the time domain and by power spectral analysis PSA in the frequency domain.
Blood pressure control was evaluated by baroreflex sensitivity BRS derived from a transfer function analysis of the PSA data. Time domain measures showed that compared to spontaneous breathing, standard deviation of normal RR intervals SDNN ms Total power ms2 a frequency domain measure of HRV was increased at 6 cpm Compared with mouth breathing, nose-only breathing decreased nLF These data suggest that reduced breathing frequency particularly 6 cpm is associated with increased parasympathetic activity, cardiac autonomic tone and blood pressure control, and that nose-only breathing is associated with altered sympathovagal balance, predominantly reflecting increased cardiac vagal activity.
Toussaint, Terry Winograd, and David R. We demonstrate relationships between the classic Euclidean algorithm and many other fields of study, particularly in the context of music and distance geometry.
Specifically, we show how the structure of the Euclidean algorithm defines a family of rhythms which encompass over forty timelines ostinatos from traditional world music. We prove that these Euclidean rhythms have the mathematical property that their onset patterns are distributed as evenly as possible: Indeed, Euclidean rhythms are the unique rhythms that maximize this notion of evenness.
We also show that essentially all Euclidean rhythms are deep: Finally, we characterize all deep rhythms, showing that they form a subclass of generated rhythms, which in turn proves a useful property called shelling.
All of our results for musical rhythms apply equally well to musical scales.

African Americans (also referred to as Black Americans or Afro-Americans) are an ethnic group of Americans with total or partial ancestry from any of the black racial groups of Africa. The term typically refers to descendants of enslaved black people who are from the United States. As a compound adjective, the term is usually hyphenated as African-American.
