Gentiana gaurii sp. nov. is described from Indian Western Himalayan region (Chamoli district). It is morphologically similar to G. ornata , G. lawrencei , and G. hexaphylla from which differ by both vegetative and sexual characters. A molecular study using the nuclear ribosomal DNA internal transcribed spacers (nrITS) support the recognition of the new species. A diagnosis, detailed taxonomic description, original photos and d...

Allium jammuense , a new species from the Trikuta Hills of Jammu and Kashmir, India, is described here as a member of Allium subgenus Cepa section Cepa . The species is discovered based on a combination of morphological characteristics and molecular evidence. Phylogenetic analysis based on nuclear ribosomal Internal Transcribed Spacer (nrITS) sequences supports that A. jammuense is closely related to A. farctum and A. roylei ,...

During the operation of a reversible pump-turbine, a hump area can easily appear under the pump condition, which will greatly affect the performance of a storage unit, with pressure pulsation being the key factor for the stable operation of a pump-turbine. Therefore, in order to explore the pressure pulsation characteristics of each flow component in the hump area, this paper first compared the full characteristics of the mode...
