Recurrences are close returns of a given state in a time series, and can be used to identify different dynamical regimes and other related phenomena, being particularly suited for analyzing experimental data. In this work, we use recurrence quantification analysis to investigate dynamical patterns in scalar data series obtained from measurements of floating(More)
Plasma edge turbulence in Tokamak Chauffage Alfvén Brésilien TCABR R. M. O. Galvão et al., Plasma Phys. Contr. Fusion 43, 1181 2001 is investigated for multifractal properties of the fluctuating floating electrostatic potential measured by Langmuir probes. The multifractality in this signal is characterized by the full multifractal spectra determined by(More)
The muscular system of a variety of the goldfish Carassius auratus gibelio fantail is investigated and described in detail for the first time. The structure of the muscular system principally corresponds to that of other Teleostei. At the same time, in contrast to other fish, in the fantail three posterior lower-keel muscles are found for the first time,(More)
Plasma resistivity is estimated in runaway discharges on TCABR tokamak from the decay of positive voltage spikes using method developed in I. El Chamaa Neto et al., Phys. Plasmas 7, 2894 (2000). In this regime, the plasma detachment from the limiter is observed experimentally indicating that plasma recombination is the main process of plasma particle(More)
A histological study of oogenesis of paliya Salvelinus alpinus complex (from larvae aged 3 weeks after hatching to the age of 3 years and 9 months) has been carried out. The fish was bred in tanks of the Federal Center of Fish Genetics and Selection (FCFGS, Ropsha, Leningrad oblast). Three-week-old larvae had primordial cells and gonia of the first orders(More)
In this work, we discuss the preliminary analysis of some disruptive plasma discharges in the TCABR tokamak, operating in the high density limit. The Fourier analysis of the MHD activity was greatly facilitated because the magnetic coils inside the TCABR were installed as to take into consideration the toroidal geometry of the system, in a straightforward(More)
