    Notes:
    A device to obtain an estimate of the spectrum of a time-variable magnetic field has been developed. The amplitude of each spectral component of the magnetic field series is obtained by analyzing with a double demodulation technique the signal generated from a flux-gate-like detector operating in open loop configuration. This device shows a sensitivity of about 1 mV/nT in the range from 0 to 300 Hz. For frequencies higher than 300 Hz the sensitivity decreases, and a correction factor that depends on the transfer function of the electronic device must be applied. The present device can be applied to environmental measurements, industrial applications, traffic control, and scientific research. © 1995 American Institute of Physics.

    We discuss the magnetization processes in sensors based on the superposition of a magneto- restrictive amorphous ribbon over a piezoelectric plate. These devices show an unusual behavior of the null condition in the response curves, which we have related theoretically and experimentally to the coercive force of the magnetic sample and to changes in the magnetic domain pattern for frequencies near the longitudinal piezoelectric resonance frequency. © 1996 American Institute of Physics.

    Background Airway hyperresponsiveness to pharmacological agonists is a common feature in subjects with allergic rhinitis.Objective The aim of this study was to investigate differences in threshold value and shape of the concentration-response curves to methacholine between subjects with perennial allergic rhinitis and subjects with seasonal rhinitis.Methods We studied a sample of 72 non-asthmatic patients with allergic rhinitis. They were subdivided into two groups: subjects with only seasonal symptoms and skin sensitization to grass and/or Parietaria pollen allergens (seasonal group, n= 38), and subjects with perennial symptoms and skin sensitization to house dust mite, alone or with other allergens (perennial group, n = 34). They were challenged with methacholine (up to 200mg/mL), and concentration-response curves were characterized by the threshold value (PC20= provocative concentration of methacholine required to produce a 20% fall in FEV1) and maximal response plateau, if possible. The measurements in the seasonal group were done within the pollen season.Results The geometric mean methacholine PC20 for subjects of the perennial group was 6.9mg/mL, compared with 23.4mg/mL in subjects of the seasonal group (P 0.01). A plateau response was detected in 16 subjects of the perennial group and in 28 subjects of the seasonal group (p 0.05). Moreover, the level of plateau was higher in subjects of the perennial group when compared with subjects of the seasonal group (23.8 ±2.0% vs 19.2 ±1.6%, P 0.05).Conclusion In subjects with allergic rhinitis, sensitization to perennial allergens is associated not only with lower methacholine threshold values, but also with lower prevalence and higher level of plateau than sensitization to pollen allergens.
