The exposition of this topic continues with a reprise of early theoretical considerations of biofeedback, the meaning and value of theta brain rhythms in human thought, creativity, and "trans personal psychology." This selection makes clear the foct that the Greens saw self-regulation by means of biofeedback not so much as an end in itself as a gateway to approaching personal development ofa mu...

www.sciencemag.org SCIENCE VOL 326 13 NOVEMBER 2009 909 COVER The Interstellar Boundary Explorer (IBEX) spacecraft has returned the first global images of the interaction of our heliosphere with the local interstellar medium. IBEX observations show a ribbon of energetic neutral atoms (reds to greens), snaking between the positions of the two Voyager spacecraft (white dots). This ribbon marks th...

Four different colors are needed to make maps that avoid adjacent countries of the same color. Because the retinal image is two dimensional, like a map, four dimensions of chromatic experience would also be needed to optimally distinguish regions returning spectrally different light to the eye. We therefore suggest that the organization of human color vision according to four-color classes (red...

Demand for Asian vegetables is rising rapidly due to changing demographics and increasing consumer awareness of their health benefits. However, growers are not familiar with growing these “foreign” crops insufficient technical information regarding suitable cultivars different regions, production schedules, disease pest susceptibility, postharvest management. The objective this study was conduc...

We use the results of Zhang [15, 16] and Davies [7] on the behavior of the heat kernel p(t, x, y) on a bounded C domain D to find again the result of Grunau-Sweers [9] concerning the estimates of the iterated Greens functions Gm,n(D). Next, we use these estimates to characterize, by means of p(t, x, y), the Kato class Km,n(D) and we give new examples of functions belonging to this class.

theoretically, in order to describe the behavior of a spectrum, a mathematical model whichcould predict the spectrum characteristics is needed. since in this study a two-state system has beenused like models which was introduced previously past and could couple with the environment, theformer ideas have been extended in this study. we use the second quantized version for writing thishamiltonian...

results: of the 50 samples tested by the elisa method, 26 samples (52%) were positive for igg . no samples were positive for igm. of the 50 samples tested by the chemiluminescence method, 28 samples (56%) were positive for igg. no samples were positive for igm. conclusions: a significant relationship between the age of the youngest child and the infection rate was seen. no significant correlati...
