Structure of 10 Be from the 12 C ( 12 C , 14 O ) 10 Be reaction
The 12C(12C,14O) two-proton pick-up reaction has been measured at 211.4 MeV incident energy to study the structure of states of 10Be up to excitation energies of 12 MeV. The measured partial angular distributions show pronounced oscillatory shapes, which were described by coupled-reaction-channels calculations. Spin-parity assignments could be derived from these characteristic shapes and two de...
متن کاملHemispheric average Cl atom concentration from 13 C / 12 C ratios in atmospheric methane
Methane is a significant atmospheric trace gas in the context of greenhouse warming and climate change. The dominant sink of atmospheric methane is the hydroxyl radical (OH). Recently, a mechanism for production of chlorine radicals (Cl) in the marine boundary layer (MBL) via bromine autocatalysis has been proposed. The importance of this mechanism in producing a methane sink is not clear at pr...
متن کاملPrevalence of hepatitis C virus infection among hemodialysis patients at a tertiary-care hospital in Mexico City, Mexico.
We determined the prevalence of hepatitis C virus (HCV) in hemodialysis patients by antibody testing and HCV RNA determination by PCR. A total of 149 patients with kidney failure with replacement therapy were tested. The prevalence of anti-HCV was 6.7% (10 of 149 patients), and viremia was detectable in 8 of 149 (5%) patients. Three of 149 patients (2%) were anti-HCV negative with detectable HC...

15 صفحه اولNatural 14 C in Saccoglossus bromophenolosus compared to 14 C in surrounding sediments
The natural radiocarbon (14C) content of whole, gut voided Saccoglossus bromophenolosus collected in Lowes Cove, Maine, USA, was compared with that of a non-voided worm, sectioned individuals, and the natural product 2,4-dibromophenol (2,4-DBP) isolated from S. bromophenolosus. In all cases, the 14C content was greater than that of the sediment from which the enteropneusts were collected. The 1...
