    Notes: A drift-Alfvén magnetoturbulence model that augments reduced magnetohydrodynamics with evolution of electron density under parallel compression and fluid advection has been studied numerically. In the Alfvénic regime, measurement of spectral transfer rates, frequency spectra, energy partitions, and the ensemble-averaged turbulent response reveals both Alfvénic and hydrodynamic characteristics. The rms turbulent frequency is Alfvénic, the energies are equipartitioned, and there is a fast, Alfvén-time scale relaxation in the turbulent response. The mean frequency is hydrodynamic, with diamagnetic and eddy straining signatures, and there is an eddy straining decorrelation appearing as a distinct, long time scale branch in the turbulent response. The decay rates and relative fluctuation strengths associated with fast and slow time scale decorrelation are in good agreement with theoretical predictions that posit a Kolmogorov spectrum in the Alfvénic regime. © 1997 American Institute of Physics.

    Technique for the experimental estimation of nonlinear energy transfer in fully developed turbulence (1996)

    Notes: A new procedure for calculating the nonlinear energy transfer and linear growth/damping rate of fully developed turbulence is derived. It avoids the unphysically large damping rates typically obtained using the predecessor method of Ritz [Ch. P. Ritz, E. J. Powers, and R. D. Bengtson, Phys. Fluids B 1, 153 (1989)]. It enforces stationarity of the turbulence to reduce the effects of noise and fluctuations not described by the basic governing equation, and includes the fourth-order moment to avoid the closure approximation. The new procedure has been implemented and tested on simulated, fully developed two-dimensional (2-D) turbulence data from a 2-D trapped-particle fluid code, and has been shown to give excellent reconstructions of the input growth rate and nonlinear coupling coefficients with good noise rejection. However, in the experimentally important case where only a one-dimensional (1-D) averaged representation of the underlying 2-D turbulence is available, this technique does not, in general, give acceptable results. A new 1-D algorithm has thus been developed for analysis of 1-D measurements of intrinsically 2-D turbulence. This new 1-D algorithm includes the nonresonant wave numbers in calculating the bispectra, and generally gives useful results when the width of the radial wave number spectrum is comparable to or less than that of the poloidal spectrum. © 1996 American Institute of Physics.

    Energy partitions in saturated compressible electron magnetoturbulence (1995)

    Notes: The two-dimensional stationary turbulence of magnetic field and density fluctuations coupled through the compressibility of parallel electron motion is shown to possess three distinct stationary states under driving of the magnetic field by the time-dependent thermal force and damping by resistivity and collisional diffusivity. The three states are the equipartitioned magnetic state that occurs when short-wavelength fluctuations interact principally through the long-wavelength magnetic field fluctuation, a magnetic energy-dominated state induced by the decorrelation of nonlinear interactions by strong diamagnetic rotation, and an internal energy-dominated state possible when the dissipation of the density is weaker than the resistive diffusion. The equipartitioned and internal energy-dominated states can occur for identical parameters, making the driven/damped turbulent steady state nonunique. © 1995 American Institute of Physics.

    Notes: Abstract. Remediation techniques for soil pollution have been studied in the aftermath of a tailing spill from a pyrite-mine holding pond in Aznalcóllar (southwest Spain). Given the extent of the accident and the characteristics of the affected area, we conclude that, after the removal of the tailings, the only feasible remediation measure involves chemical immobilization of the pollutants. The best treatment tested proved to be liming in combination with amendment materials such as soils rich in iron oxides and clay. Monitoring for 3 years has demonstrated that the system is effective for reducing the solubility of the most mobile forms of the main pollutant elements, although further monitoring is recommended.

    Surimi-Derived Elver Substitutes: Microscopic Appearance and Physicochemical and Sensory Properties (2002)

    Notes: : Elver substitutes made from kamaboko-type fish gels have recently been introduced onto the market in Spain. Kamaboko is made by addition of 2.5 to 3.0% salt, and optionally other additives, to surimi (minced fish). The present study investigated the usefulness of microscopy techniques for characterizing the structure and composition of two elver substitutes of this type. Sensory and physicochemical analyses were also performed, with the aim of defining the organoleptic characteristics of these products. The results obtained indicate that microscopy techniques are useful for rapid identification of certain additives in products of this type. Furthermore, many of the between-brand differences in microscopic appearance showed clear correspondence with differences in physicochemical and sensory properties.

    Siberian hamster: a new indoor source of allergic sensitization and respiratory disease (2002)

    Notes: Background: The identification of ‘unknown’ allergic sensitizations may determine the prognosis and treatment of patients with respiratory airway disease. Currently, the presence in homes of ‘exotic’ animals as pets is increasing. In this article the Siberian hamster or dwarf hamster (Phodopus sungorus) was identified as a new indoor source of aeroallergens and respiratory disease. Methods: The subjects were six outpatients who were treated for asthma and rhinitis. Siberian hamster hair extract was prepared with a standard wt/vol method, and patients were skin-prick tested with the extract. Serum-specific immunoglobulin (Ig)E against the Siberian hamster, common hamster (Cricetus cricetus) and golden hamster (Mesocricetus auratus) was determined. IgE-immunoblotting was also performed for all six sera. Specific bronchial challenge was carried out with the Siberian hamster extract. Results:  Skin prick tests (SPT) with the Siberian hamster extract, and specific IgE-antibodies against Siberian hamster, were strongly positive in all six patients. Determinations of specific IgE-antibodies against C. cricetus and M. auratus were negative in all patients. IgE-immunoblotting of the sera revealed two IgE-binding fractions (MW 18 and 32 kDa) in five of the six sera. Specific bronchial provocation tests resulted in early asthmatic responses in the two patients who were challenged. Conclusions: The present study reveals the Siberian hamster to be able to induce both sensitization and disease, and this species of hamster should be taken into consideration as a cause of respiratory disease in exposed subjects. A noteworthy finding was the lack of sensitization in our patients to common hamster allergens (M. auratus and C. cricetus) that are usually tested when hamster allergy is suspected.
