Detection of molecular hydrogen at z = 1 . 15 toward HE 0515 – 4414 ⋆
A new molecular hydrogen cloud is found in the sub-damped Lyα absorber [logN(H i) = 19.88± 0.05] at the redshift zabs = 1.15 toward the bright quasar HE 0515–4414 (zem = 1.71). More than 30 absorption features in the Lyman band system of H2 are identified in the UV spectrum of this quasar obtained with the Space Telescope Imaging Spectrograph (STIS) aboard the Hubble Space Telescope. The H2-bea...
متن کاملRecent Progress Toward Hydrogen Medicine: Potential of Molecular Hydrogen for Preventive and Therapeutic Applications
Persistent oxidative stress is one of the major causes of most lifestyle-related diseases, cancer and the aging process. Acute oxidative stress directly causes serious damage to tissues. Despite the clinical importance of oxidative damage, antioxidants have been of limited therapeutic success. We have proposed that molecular hydrogen (H(2)) has potential as a "novel" antioxidant in preventive a...
متن کاملDetection of molecular hydrogen in the atmosphere of Mars.
Four hydrogen (H2) lines have been detected in a spectrum of Mars observed with the Far Ultraviolet Spectroscopic Explorer. Three of those lines are excited by the solar Lyman beta photons. The line intensities correspond to a column H2 abundance of 1.17 (+/-0.13) x 10(13) per square centimeter above 140 kilometers on Mars. A photochemical model for the upper atmosphere that simulates the obser...
متن کاملMolecular detection of pathogenic Leptospira in Iran
Leptospirosis is an acute infectious, systemic and septisemic disease which had recent outbreaks in some parts of Iran especially in north provinces. Rapid detection is a critical step for treatment and control of this disease. In this research a PCR based method was evaluated for detection of Iranian local endemic serovars. All reported endemic serovars of Leptospira including Leptospira gri...
متن کاملIsotope effects in complex scattering lengths for He collisions with molecular hydrogen
We examine the effect of theoretically varying the collision-system reduced mass in collisions of He with vibrationally excited molecular hydrogen and observe zero-energy resonances for select atomic “hydrogen” masses less than 1 u or a “helium” mass of 1.95 u. Complex scattering lengths, state-to-state vibrational quenching cross sections, and a low-energy elastic scattering resonance are all ...
