The registration of periodic variations spectral line widths serves as the main method for observing torsional Alfvén waves. Theoretically, seems valid, yet it entails a number caveats when applied to data. For instance, amplitudes these observations should vary with changes location on disk and they be associated no intensity oscillations. We analyze extensive observational material non-therma...

methadone is widely being used for opioid substitution therapy. however, the administration of methadone to opioid dependent individual is frequently accompanied by withdrawal syndrome and chemical dependency develops. other than that, it is also difficult to retain patients in the treatment programme making their retention rates are decreasing over time. this article is written to higlights th...

We present time-series spectroscopy and multi-band photometry of the sdBV PG1605+072 carried out simultaneously at the Calar Alto 2.2m and 3.5m telescopes. The periodogram analysis of the radial velocity curves reveals three frequencies at 2.078, 2.756, and 1.985 mHz for Hβ and at 2.076, 2.753, and 1.978 mHz for Hγ . The corresponding radial velocity amplitudes are 12.7, 8.0, and 7.9 km/s for H...

This paper presents new laboratory data on long-wave (surf-beat) forcing by the random breaking of shorter gravity water waves on a plane beach. The data include incident and outgoing wave amplitudes, together with shoreline oscillation amplitudes at long-wave frequencies, from which the correlation between forced long waves and short-wave groups is examined. A detailed analysis of the cross-sh...

We use the infrared consistency of one-loop amplitudes in N = 4 Yang-Mills theory to derive a compact analytic formula for a tree-level next-to-next-to-maximal helicity-violating gluon scattering amplitude in QCD, the first such formula known. We argue that the infrared conditions, coupled with recent advances in calculating one-loop box coefficients, can give a new tool for computing tree-leve...

We identify a large class of one-loop amplitudes for massless particles that can be constructed via unitarity from tree amplitudes, without any ambiguities. One-loop amplitudes for massless supersymmetric gauge theories fall into this class; in addition, many non-supersymmetric amplitudes can be rearranged to take advantage of the result. As applications, we construct the one-loop amplitudes fo...

this research deals with the concept of uniqueness in creativity as one of the artist's concerns and her personal features differentiates her from her peers in literary approach and critical view horizon based on her learned knowledge and literature.the reflection of such concept can be found in the book teyf-e- al-khialwritten by sharif al-murtazain both poetry and its criticism. the poet...

PURPOSE In infants with frequent therapy resistant seizures (TRS-infants), clinical detection of pyridoxine-dependency (PD) or -responsiveness (PR) occurs by empirical intravenous (IV) pyridoxine administration during recording of the EEG. However, in undiagnosed TRS-infants it is still unclear to what extent EEG alterations by pyridoxine-IV are attributable to PD/PR or to non-specific response...

abstract aim and background: evidences show that both negative and positive affects play role in tendency to use substances, giving this issue, the current study was conducted in other to investigate relationships between distress tolerance, negative and positive urgency with severity of dependence and craving in people with substance dependency. methods and materials: the method of this resear...
