Structural-functional roles of microtubules in cells and cell appendages are becoming well established . A "static" supportive function could be assigned to the microtubular arrays in the axonemes of Heliozoa (Actinophrys, 7 ; Echinosphaerium, 18) and Radiolaria (Nassellaria, 5), in the tentacles of Suctoria (Acineta, 3 ; Tokophrya, 12), and in the endosprits of the ciliate Cyathodinium (9) . M...

We report the discovery of sipunculan worms from the Lower Cambrian Maotianshan Shale, near Kunming (southwest China). Their sipunculan identity is evidenced by the general morphology of the animals (sausage-shaped body with a slender retractable introvert and a wider trunk) and by other features, both external (e.g. perioral crown of tentacles, and hooks, papillae and wrinkle rings on the body...

It is shown that square free set theoretic involutive non-degenerate solutions of the Yang-Baxter equation whose associated permutation group (referred to as an involutive Yang-Baxter group) is abelian are retractable in the sense of Etingof, Schedler and Soloviev. This solves a problem of Gateva-Ivanova in the case of abelian IYB groups. It also implies that the corresponding finitely presente...

A series of experiments was performed to determine whether sign-tracking would occur in rats with intravenous (i.v.) cocaine as the unconditioned stimulus. In Experiment 1, a retractable lever paired with food produced strong sign-tracking, but a lever paired with one of three doses of i.v. cocaine did not elicit any approach or contact behavior. Experiment 2 demonstrated that doses of cocaine ...

biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

Abstract In recent years, as a new type of gob-side entry retaining method, roadway automatically formed by roof cutting and pressure releasing (RAFRCPR) has been widely used in China. Under the condition deep mining, deformation gangue rib is difficult to control, it for traditional I-shaped steel provide needed support. To effectively control rib, U-shaped retractable prevention structure (UR...

The genus Pallisentis has been mostly found among the freshwater fishes of Channidae family. ophiocephali is characterized with some unique characters proboscis, hooks, and spines. However, initial description a little sketchy yet not updated. present study communicates detail morphology an acanthocephalan species obtained from two host family—Channa striatus Channa punctatus—during one-year su...

Public bulletin boards are widely used in various public places, but due to the large size of billboards, it is not easy carry, and traditional billboards integrated, when need be transferred, limited storage space vehicle needs occupied It extremely inconvenient, at night, install additional light sources illuminate them, which greatly increases energy consumption. Based on this paper designed...
