A new species of spikemoss from Yunnan Province of China, Selaginella dianzhongensis, is described and illustrated based on evidence from gross morphology, micromorphology and molecular phylogeny.S.dianzhongensis is most similar to S.amblyphylla in its habit of creeping stem, leaf size, and obviously dimorphic sporophylls, but is distinct by its ve
The Notch signalling pathway controls differentiation of hair cells and supporting cells in the vertebrate inner ear.Here, we have investigated whether Numb, a known regulator of Notch activity in Drosophila, is involved in this process in the embryonic chick.The chicken homologue of Numb is expressed throughout the otocyst at early stages of devel
Slump is a workability-related characteristic of concrete mixture.This paper investigates the efficiency of a novel optimizer, namely ant lion optimization (ALO), for fine-tuning of a neural network (NN) in the field of concrete slump prediction.Two well-known optimization techniques, biogeography-based optimization (BBO) and grasshopper optimizati
The cleavage activity of synthetic ribozymes needs to be characterized by reliable and rapid methods.A chromatographic method to simultaneously quantitate the amounts of substrate, cleavage fragments and ribozyme is described.The method allows the rapid normalization of analytical data because the sum of Laptop Power Adaptor the 260-nm peak areas o
The aim of the present study was to investigate the effect of educational and motivational self-talk on dart throwing performance with different difficulties.A total of 60 beginners and right-handers with an age range of 22 to 28 years were randomly selected and randomly divided into three groups of educational self-talk, motivation and control.The
