Wind erosion is one of the major meteorological hazards in Ningxia, and climate change has caused changes wind erosion–climatic activity recent years. This study uses factor (C) proposed by Food Agriculture Organization United Nations to assess impact on erosion–climate erosion, results show that (1) distribution degree Ningxia region central > northern southern. Seasonally, it higher spring...

The replacement of group 10-based materials by superatoms has gained great attention due to studies presenting similarities in electronic character and reactive nature between pairs. The current study extends the concept to systems of larger and varied composition as the pairs PdO(+) and ZrO(2)(+) as well as NiO(+) and TiO(2)(+) are interacted with C(2)H(4) and CO through DFT calculations and g...

Cyclodextrin-based host-guest chemistry has been exploited to facilitate co-crystallization of recombinant human acid β-glucosidase (β-glucocerebrosidase, GlcCerase) with amphiphilic bicyclic nojirimycin analogues of the sp(2)-iminosugar type. Attempts to co-crystallize GlcCerase with 5-N,6-O-[N'-(n-octyl)iminomethylidene]nojirimycin (NOI-NJ) or with 5-N,6-S-[N'-(n-octyl)iminomethylidene]-6-thi...

It is well known that approach of the classical R-matrix formalism to the specific infinitedimensional Lie algebras can be used for systematic construction of field and lattice integrable dispersive systems (soliton systems) as well as dispersionless integrable field systems (see [1]-[17] and the references there). The Lie algebra of pseudo-differential operators (PDO) leads to the construction...

INTRODUCTION Composite mesh prostheses incorporate the properties of multiple materials for ventral hernia repair. This study evaluated a polypropylene/ePTFE composite mesh with a novel internal polydioxanone (PDO) absorbable ring. METHODS Composite mesh was placed intraperitoneally in 16 pigs through an open laparotomy and explanted at 2, 4, 8, and 12 weeks. Intraabdominal adhesions were mea...

The formation, thermal decomposition, and reduction of small PdO particles were studied by high-resolution transmission electron microscopy and selected area electron diffraction. Well-defined Pd particles (mean size of 5-7 nm) were grown epitaxially on NaCl (001) surfaces and subsequently covered by a layer of amorphous SiO2 (25 nm), prepared by reactive deposition of SiO in 10(-2) Pa O2. The ...
