We present suggestive evidence for an inverse energy cascade within Jupiter’s atmosphere through a calculation of the power spectrum of its kinetic energy and its c...

High-resolution spectroscopy measures the transitions between energy levels with high accuracy; typically, uncertainties are in the region of 1 part in 108. Although it is possible, under favorable circumstances, to obtain this sort of accuracy by fitting effective Hamiltonians to observed spectra (see Bauder 2011: Fundamentals of Rotational Spectroscopy, this handbook), such ultrahigh accuracy...

the synthesis, spectroscopic and magnetic characterization of a series of new alkoxo-bridged binuclear copper (ii) compounds are described. all complexes have the general formula [cu (m-or)(l)2]2(clo4)2 · x h2o, in which m-or = ch3o-, c2h5o- or c3h7o-, l = 2-amino-4-methylpyridine (abbreviated a4pic) and 2-amino-5-methylpyridine ( abbreviated a5pic). the title compounds all consist of dinuclear...

the coupling of tetrazotised 1,8-diaminonaphthalene with 1,3-dicarbonyl compounds [acetylacetone,methylacetoacetate and acetoacetanilide] yielded a new series of tetradentate ligand systems. analytical, ir,1h nmr and mass spectral data indicate that the compounds exist in the intramolecularly hydrogen bondeddihydrazone form. dibasic tetradentate n2o2 coordination of these compounds in their [ml...

We study energy dependencies of quasi-periodic oscillations from a number of black hole X-ray binaries. The selected sources were observed by RXTE at time periods close to state transitions and showed QPO in the 1–10 Hz range. We have constructed QPO rootmean-square energy spectra, which provide information about underlying physical process leading to QPO generation. These spectra show an inter...

N K and 3d atom L absorption spectra of hexacyano complexes in solid K Fe(CN) , Na Fe(CN) , K Cr(CN) , 2,3 4 6 4 6 3 6 K Mn(CN) , K Fe(CN) , and K Co(CN) have been measured by detecting the total electron yield. The N K spectra of the 3 6 3 6 3 6 complexes are very similar and differ only in intensity of the lowest-energy absorption band. The intensity of this feature 32 systematically decrease...

Understanding of the major sources, sinks, and reservoirs of energy in the ocean is briefly updated in a diagram. The nature of the dominant kinetic energy reservoir, that of the balanced variablity, is then found to be indistinguishable in the observations from a sum of barotropic and first baroclinic ordinary quasi-geostrophic modes. Little supporting evidence is available to partition the sp...

The deposition of x-ray energy resulting from the microexplosion i.o an inertial confinement fusion reactor and the subsequent thermal response of candidate wall coating and structural materials is examined. Evaporation losses and resulting melt layer thicknesses for these materials exposed to a variety of different x-ray energies and spectra are calculated. Softer x-ray energy spectra absorbed...

Aims. We investigate the signature of the photospheric albedo contribution in solar flare hard X-ray spectra, the effect of low energy cutoffs in electron spectra, and the directivity of hard X-ray emission. Methods. Using Ramaty High Energy Solar Spectroscopic Imager (RHESSI) flare data we perform a statistical analysis of spatially integrated spectra and positions of solar flares. Results. We...
