Sentence examples for using a beta attenuation from inspiring English sources

Outdoor PM2.5 concentrations were monitored and recorded hourly using a beta attenuation monitor (BAM; model 1020; Met One Instruments Inc., Grant Pass, OR, USA) with air inlets placed outside of the same windows as aethalometers.

Moreover, attenuation was not performed because attenuation correction using a linear attenuation coefficient of radionuclides other than for clinically relevant radionuclides is challenging.

Typically, SPECT attenuation correction is performed using a co-registered attenuation map based on computed tomography (CT) images.

One attenuation compensation method involves a multiplicative postprocessing correction using an assumed constant attenuation coefficient.

Adipose tissue was highlighted and computed using an attenuation range from −190 to −30 Hounsfield units.

In particular, for particulate matter, PM10 were currently obtained using beta-ray attenuation monitors and corrected TEOM (Tapered Element Oscillating Microbalance).

Hourly PM2.5 is measured using the Met-One BAM with a PM2.5 SCC beta attenuation method.

In the mammary epithelium, attenuation of TGF-β signaling using a dominant negative type II transforming growth factor-beta receptor (TβRII) resulted in lobular alveolar hyperplasia and an increased rate of tumor formation in conjunction with a TGF-α transgene [ 8]; however, decreased pulmonary metastasis resulted when dominant negative TβRII was expressed along with a c-Neu transgene [ 8, 9].

The networks use tapered-element oscillating microbalance and beta attenuation monitor samplers (Ville de Montréal 2010) for PM2.5 measurements and ultraviolet absorption analyzers for ozone.

Attenuation was corrected using a 137Cs single photon transmission measurement.

A similar pattern of growth attenuation was observed using a cell counter (data not shown).
