On some properties of the water-vapor spectrum and their relations to atmospheric radiation

In the present paper we investigate the physical consequences of the fact that the water vapor spectrum in the far infrared consists of a large number of narrow lines. It will be shown that the average width of these lines is much smaller than the intervals which could be resolved with the spectrographs used hitherto. For thick layer of vapor complete absorption is nevertheless reached in most parts of the spectrum. It can be shown that under such circumstances the total absorption is approximately proportional to the air pressure in the absorbing layers and is inversely proportional to the square root of the absolute temperature. There is an additional variation with temperature of a more complex type which cannot yet be quantitatively evaluated from the available measurements, but it is probably not very large

Weather and Plant-Development Data as Determinants of Grazing Periods on Mountain Range

Fundamental in economical range-resource management is the determination of proper grazing periods. It is of prime importance to be able to establish a date in the spring when the range has produced sufficient feed to keep livestock in thrifty condition, when it is reasonably safe from excessive trampling and packing of the soil, and when the more important key forage plants have attained sufficient development to withstand grazing use. Such opening dates, as well as the time to defer and rotate grazing and to remove livestock from the range, are dependent in part on the prevailing weather conditions and on the dates when active growth of the forage plants begins and when subsequent developmental stages of the plants are reached

Socioeconomic Status/Class and Asian Americans

This brief discusses the recent influx of immigrants from Asia and broad spectrum of individuals that are included in the ethnoracial grouping “Asian American”. It also looks at income data and polls reporting on satisfaction with economic status. There are many factors that come factor into the socioeconomic status of Asian Americans including but not limited to: level of education, job type, and ethnic background

Time-asymmetry of probabilities versus relativistic causal structure: an arrow of time

There is an incompatibility between the symmetries of causal structure in relativity theory and the signaling abilities of probabilistic devices with inputs and outputs: while time-reversal in relativity will not introduce the ability to signal between spacelike separated regions, this is not the case for probabilistic devices with space-like separated input-output pairs. We explicitly describe a non-signaling device which becomes a perfect signaling device under time-reversal, where time-reversal can be conceptualized as playing backwards a videotape of an agent manipulating the device. This leads to an arrow of time that is identifiable when studying the correlations of events for spacelike separated regions. Somewhat surprisingly, although time-reversal of Popuscu-Roerlich boxes also allows agents to signal, it does not yield a perfect signaling device. Finally, we realize time-reversal using post-selection, which could lead experimental implementation.Comment: 4 pages, some figures; replaces arXiv:1010.4572 [quant-ph
