The authors offer a partial portrait of overall emissions, concentrating on residential electricity and fuel use and the mileage traveled by cars and trucks — factors that contribute about half of overall carbon emissions.
Their radio emission is concentrated along a narrow cone, producing a series of pulses corresponding to the rotation of the neutron star, much like the beacon from a rotating lighthouse lamp.
Since the emission is concentrated in a very compact region (with typical size r⩽0.1 pc) and it is not possible to obtain resolved images of the source, spectroscopic studies of this radiation represent the only valuable key to constrain the physical properties of matter and its structure in the center of active galaxies.
Treatment of the cells with [Ru] (20 μM) and PhSH (100 μM) for 20 min led to the characteristic staining of ethidium bromide in the red channel, with the emission mainly concentrated in the nuclei and nucleoli (Fig. 9f), while almost no signal was observed in the green channel (Fig. 9d), suggesting that the uncaging had been very efficient.
Global carbon emissions are concentrated in a few nations with China and the US alone producing 39% of global emissions.
Logging emissions are concentrated at the beginning of the disturbance event, as biomass is removed and there is collateral damage to nearby trees.
An analysis of the highly detailed maps yields the following findings: First, CO2 emissions are concentrated in over-urbanized areas, where the population density is higher than 5000 people/km2.
Thermophotonics is a recent development of this concept where the emitter is "active", namely a heated diode, increasing the rate of energy transfer for a given emitter temperature and concentrating emission in an energy range more suited for conversion by the receiver.
Surprisingly, despite its significant in vitro DNA binding affinity, the intracellular emission was not concentrated in the cell nuclei, but showed instead a cytosolic filamentous pattern, consistent with mitochondrial localization of the dye.
The aim of the present study was to conduct a randomized placebo-controlled trial to test the efficacy of a white LED device whose light emission was relatively concentrated in shorter wavelengths (the "Litebook", The Litebook Company Ltd., Alberta, Canada).
