The thermal sound

attenuation coefficient [[alpha].

T] = average temperature v = velocity p = Pressure P = perimeter of the shaft Pr = Prandtl number W = thickness of the shaft wall x = height of interests Greek symbols a = temperature

attenuation coefficient [DELTA] = difference [epsilon] = roughness [eta] = normalized temperature rise in the fire floor due to fire [theta] = normalized temperature [lambda] = thermal conductivity [mu] = dynamic viscosity v = kinematic viscosity [?

The effective

attenuation coefficient was then estimated according to

The integral version of the primary production model needs (as initial data) an irradiance estimate for the entire PAR spectrum (the spectral values of the incident irradiance and diffuse

attenuation coefficient are not necessary).

x] is the one used in Eq (1) (usually the one used for air under normal pressure) and

attenuation coefficient [xi] is calculated from Eq (1).

CDOM]([lambda]), but

attenuation coefficient spectra of filtered water, [c.

A good match between the amplitude of the wakes and the

attenuation coefficient is evident on some days.

5 shows the values of the longitudinal sound wave

attenuation coefficient after analysing acoustic properties of wood chipboard and gypsum cardboard.

The

attenuation coefficient describes the loss of ultrasonic energy due to scattering.

The mass

attenuation coefficient is a material property of the mat that can be determined by a calibration experiment or from literature (Olson and Arganbright 1981, Moschler and Dougal 1988, Cullity and Stock 2001).

The mean linear

attenuation coefficients in the mid labial region in 1 mm steps from incisor tip to the root apex were measured and calibrated against the aluminium wire standard with a linear correlation coefficient of 1.

Beam

attenuation coefficient was measured with the same instrument.

The data consist of the concentrations of OAS in ice and under-ice water, the spectra of the beam

attenuation coefficient for filtered and unfiltered water (for ice they are determined from meltwater), and the values of quantum irradiance above and below ice cover.

An algorithm called Microvis (2000) developed by Embrapa Agricultural Instrumentation (CNPDIA--Sao Carlos, Brazil) was used for image reconstruction, using tomographic units (TU) related to the soil linear

attenuation coefficient [mu] ([cm.

Moreover, detection of changes in the refractive indices of a medium is more sensitive parameter than X-ray

attenuation coefficient or mismatch of ultrasonic acoustic impedance.
