a b s t r a c tDuring the investigation of rust fungi collected in western China, two morphologically different rusts were found on Cornus plants. From uredinial and telial morphology, they belong to Thekopsora, and they were distinct from previously described Pucciniastrum corni on Cornus and other Thekopsora species. Therefore, they were described as new species, Thekopsora lanpingensis and T. triangula, respectively. Phylogenetic analyses by ITS1-5.8S-ITS2 and 28S rRNA gene partial sequences also supported the morphological results. The previously described Pucciniastrum corni in China was corrected as T. triangula. The presence of P. corni in China was not confirmed.
Solid base CaO was prepared and characterized, which was used to catalyze depolymerization of lignite in supercritical methanol. Methanolysis products were analyzed by gas chromatography-mass spectrometry (GC-MS) and Fourier transform infrared spectroscopy (FTIR). The results showed that the solubility of methanolysis products in organic solvent increased, the majority species of methanolysis products were aliphatic hydrocarbon and oxygenated compounds such as alkyl substitution phenol. CaO can catalyze selective depolymerization of lignite with the reaction of cleavage of ether bond under given condition.
The penetration of multi-touch devices have created a new generation of users comfortable with the gestures associated with such devices. Developers have already embraced such trends by capturing and handling them in their applications. We propose a novel approach to use mobile devices as system controls for applications. Unlike existing approaches, our solution has three key features. First, it is flexible to customize for different applications. Second, it allows multiple users to interact with the application as well as to interact with each other. Third, it fully supports multi-touch and user-defined gestures. The feasibility of our solution is demonstrated through the implementation test we have made for web applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
