The self-complexation of mono-benzimidazole functionalized β-cyclodextrins was investigated. The unique molecular structure employed as supramolecular nanovalves were installed on the external surface of mesoporous silica to assemble mechanized silica nanoparticles, which showed pH-triggered release property.

We show how to improve one of the constructors of separation algebras to increase modularity and expressibility. Our technique has advantages for both paper and mechanized proofs. Our results are implemented in Coq.

the purpose of this study was to evaluate the species-environment relationships in arid and semi-arid rangelandsof nodushan, yazd. the plant species cover and the environmental variables were measured at 9 sites. soil sampleswere taken for measurement of 12 attributes in 0-10 cm and 10-80 cm layers. vegetation was classified using twowayindicator species analysis (twinspan). data was analyzed u...
