To examine spatial scale-dependent variation in the vegetation in Mu Ussandy land, in the semi-arid area of NW China, two transects (5 kmin length, meeting at right angle) were set, and two vegetation attributes(quantitative descriptors), vegetation cover and number of plant species, wereinvestigated. The data were analyzed combining geostatistics and(More)
MIL-101 is a chromium terephthalate-based mesoscopic metal-organic framework and one of the most porous materials reported to date. In this study, we investigate the adsorption of CO(2) and CH(4) in dehydrated and hydrated MIL-101 and the effect of terminal water molecules on adsorption. The atomistic structures of MIL-101 are constructed from experimental(More)
The amplitude and periodicity of the re#ection high-energy electron di!raction (RHEED) oscillations displayed strong temperature dependence in homoepitaxy of SrTiO 3 (STO) "lms. Combining with the AFM observations, the results suggest that the oscillations are not directly related to the layer-by-layer growth. ( 2000 Elsevier Science B.V. All rights(More)
Neutrophilic sebaceous adenitis (NSA) was initially described in dogs, with an unclear etiology. Only three human cases have been reported.1–3 We reported another case in an Asian man, who responded well to oral isotretinoin. The 38-year-old man had suffered from erythematous plaques with satellite papules on bilateral cheeks for 3 months. The lesions(More)
A molecular simulation study is reported for CO(2) adsorption in rho zeolite-like metal-organic framework (rho-ZMOF) exchanged with a series of cations (Na(+), K(+), Rb(+), Cs(+), Mg(2+), Ca(2+), and Al(3+)). The isosteric heat and Henry's constant at infinite dilution increase monotonically with increasing charge-to-diameter ratio of cation (Cs(+) < Rb(+)(More)
