group results in more non-coplanar conformation of the DPNA species in the 6F-alpha NA PI, as compared to that of the beta-tethering in the 6F-beta NA PI, therefore producing a higher energy barrier that prevents the back charge transfer processes, consequently leading to the WORM vs. flas...
(H7) respectively, these two strains have typical bipyramidal parasporal inclusions.They not only have high biological activities on diamondback moth and beet armyworm,but also are toxic to insects of Diptera.K9903 has cryⅠAa,cryⅠAb,cryⅠAc,cryⅠE and cryⅡ genes,while K9805 has cryⅠAa...
Because of instantaneous multi-tooth contact and line-contact, an Archimedean spiroid worm drive is sensitive to manufacturing and assembly errors. To solve the sensitivity of the spiroid worm drive (SWD), this paper proposes a kind of two-generating-surface method (TGSM) that transforms the co...
A roundworm, also known as a nematode, is a very small worm that lives in the intestines of people, pigs, and other animals. Discover the physical characteristics and taxonomic classification of roundworms as well as examples of roundworms that infect humans and how these infections are treated...
Sedimentary characteristics of worm reefs constructed by the sabellariid polychaete Phragmatopoma lapidosa Kinberg were examined to determine whether sediments of specific size and/or composition were selected for use in tube construction. Sediment size class distributions and CaCO 3 content were determine...
