A comparison of physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech to subjective judgments of audibility threshold, MCL and UCL for three normally hearing listeners

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

Input/output measurements of otoacoustic emissions and differential diagnosis of cochlear function

This study provides detailed information on the ability of healthy ears to generate distortion product otoacoustic emissions (DPOAEs).

La educación inclusiva en la experiencia educativa de la congregación de hermanas oblatas de San Francisco de Sales en el Ecuador: el caso de la Unidad Educativa San francisco de Sales de Alausí

La Unidad Educativa “San Francisco de Sales” de Alausí regentada por las Hermanas Oblatas tiene un reconocido historial en la vida del pueblo de Alausí, enclavado en el perfil Andino y fiel testigo del encuentro de dos culturas diferentes, la Europea y la Ecuatoriana, relacionadas con la región central de nuestro país. La Iglesia en aquel tiempo, asumió diversidad de tareas, la mayor parte de ellas orientadas hacia la cultura y la educación. Las políticas educativas, siempre asociadas al perfil de los gobiernos que se iban sucediendo uno tras otro, a lo largo del siglo diecinueve, poco o ningún favor hicieron a esta estratégica gestión. Es en 1895, que el país comienza a transitar por una corriente educativa sin influencias dogmáticas. Este es el caso de las dos Instituciones regentadas por la Congregación de las hermanas Oblatas de San Francisco de Sales, la escuela Isidro Narváez de niños indígenas y la Unidad Educativa San Francisco de Sales de niños y jóvenes mestizos, que hoy al compartir la propuesta de inclusión educativa, los directivos han comenzado la fusión, y han diseñado alternativas que benefician y fortalecen el aprendizaje.

First CRDS-measurements of water vapour continuum in the 940nm absorption band

Measurements of near-infrared water vapour continuum using continuous wave cavity ring down spectroscopy (cw- CRDS) have been performed at around 10611.6 and 10685:2 cm1. The continuum absorption coefficients for N2- broadening have been determined for two temperatures and wavenumbers. These results represent the first near-IR continuum laboratory data determined within the complex spectral environment in the 940nm water vapour band and are in reasonable agreement with simulations using the semiempirical CKD formulation.

Pure water vapor continuum measurements between 3100 and 4400 cm1: Evidence for water dimer absorption in near atmospheric conditions

Despite the potentially important role that water dimers may play in the Earth’s energy balance, there is still a lack of firm evidence for absorption of radiation by dimers in near-atmospheric conditions. We present results of the first high-resolution laboratory measurements of the water vapor continuum absorption within the 3100–4400 cm1 spectral region at a range of near-room temperatures. The analysis indicates a large contribution of dimer absorption to the water vapor continuum, significantly in excess of that predicted by other modern representations of the continuum. The temperature dependence agrees well with that expected for dimers.

Achieving accurate FTIR measurements on high performance bandpass filters

The sources of ordinate error in FTIR spectrometers are reviewed with reference to measuring small out-of-band features in the spectra of bandpass filters. Procedures for identifying instrumental artefacts are described. It is shown that features well below 0.01%T can be measured reliably.
