A rocket-borne spectrograph detected H I Lyman alpha emission from the disk of Saturn and from the vicinity of the planet. The signal is consistent with an emission brightness of 700 rayleighs for the disk and 200 rayleighs for the vicinity of Saturn. The emission from the vicinity of the planet may be due to a hydrogen atmosphere associated with the saturnian ring system.

The Wisconsin H-Alpha Mapper (WHAM) Northern Sky Survey is revealing that many intermediate-velocity (|v LSR | ≤ 100 km s −1) neutral clouds and complexes have an associated ionized component. We present the first map of the Hα emission from an intermediate-or high-velocity structure: Complex K. This large, high-latitude feature stretches from ℓ ≈ 10 • to 70 • , b ≈ +30 • to +70 • and peaks in ...

The most recent generalization of octonion Fourier transform (OFT) is the linear canonical (OLCT) that has become popular in present era due to its applications color image and signal processing. On other hand Wigner distribution (WD) analysis cannot be excluded. In this paper, we introduce novel integral coined as domain (WDOL). We first propose definition one dimensional WDOL (1DWDOL), extend...

abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...

Virtual acoustic environments (VAEs) are commonly realized via dynamic binaural synthesis. Therefore, anechoic audio is convolved in real time with head related impulse responses (HRIRs) or binaural room impulse responses (BRIRs). Binaural filters are exchanged inaudibly and in real time according to the listener’s head movements, thus providing a realistic auditory experience. From Lord Raylei...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...

in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

Neptune has been observed on seven occasions with the International Ultraviolet Explorer Observatory (IUE, Boggess et al. 1978) in an attempt o detect planetary H Ly-a line emission. The observing technique is the same as previously employed in IUE observations of Uranus, described in detail by Clarke et al. (1986), and consists of spatial separation of the planetary emission from background ge...
