The Min River is the largest river in Fujian Province southeastern China. construction of a series dams along upper reaches River, especially Shuikou Dam, which started filling 1993, modified flow processes at lower leading to significant increase low-flows and slightly decrease flood-flows. At same time, reservoirs have more effects on sediment transport process than by trapping most reservoir...

The formation of radicals in the gas phase oxidation of cyclohexane over metal oxides was studied using spin trapping and EPR spectroscopy; the results confirmed that during the catalytic initiation, the oxygen responsible for the radicals formation originates from the lattice of the metal oxide.

The electronic structure of the cation of [Fe(ptz)(6)](BF(4))(2), a prototype of a class of complexes that display light-induced excited-state spin trapping (LIESST), has been investigated by time-independent and time-dependent density-functional theories. The density of states of the singlet ground state reveals that the highest occupied orbitals are metal centered and give rise to a low spin ...

A general definition of a black hole is given, and general ‘laws of black-hole dynamics’ derived. The definition involves something similar to an apparent horizon, a trapping horizon, defined as a hypersurface foliated by marginal surfaces of one of four non-degenerate types, described as future or past, and outer or inner. If the boundary of an inextendible trapped region is suitably regular, ...

Sediment samples from the coastal area of Asaluyeh harbor were collected during autumn and spring 2015. The acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) were measured to assess the sediment quality and potential ecological risks. The average concentrations (and relative standard deviation (RSD)) of AVS in the industrial sediments were 12.32 μmol/g (36.91) and 6.34 μmol...

OBJECTIVE To determine the time and financial costs of programs for live trapping feral cats and determine whether allowing cats to become acclimated to the traps improved trapping effectiveness. DESIGN Prospective cohort study. ANIMALS 107 feral cats in 9 colonies. PROCEDURE 15 traps were set at each colony for 5 consecutive nights, and 5 traps were then set per night until trapping was ...
