in this paper, we have de ned and studied a generalized form of topological vectorspaces called s-topological vector spaces. s-topological vector spaces are de ned by using semi-open sets and semi-continuity in the sense of levine. along with other results, it is provedthat every s-topological vector space is generalized homogeneous space. every open subspaceof an s-topological vector space is ...
There is no other naturally occurring defense agent against cancer that has a stronger effectthan paclitaxel, commonly known under the brand name of Taxol®. The major drawback for themore widespread use of paclitaxel and its precious precursor, 10-deacetylbaccatin III (10-DABIII), is that they require large-scale extraction from different parts of yew trees (Taxus species),cell cultures, taxane...
Vegetative propagation of pear rootstocks using semi hardwood cuttings The objective of this work was to evaluate the technical viability of the vegetative propagation of the pear rootstocks ‘Taiwan Nashi-C’, ‘Taiwan Mamenashi’ (Pyrus calleryana Dcne.) and ‘Seleção IAC-1’ (Pyrus spp.) using semi-hardwood cuttings. The experiment was conducted in a nursery with an intermittent mist system at the...
