Efficiency of light-scattering aerosol particle counters.
The counting efficiency as a function of particle size has been calculated for a particular forward scattering aerosol particle counter that uses white light illumination for spherical particles with indexes of refraction 1.33-0i, 1.40-0i, 1.50-0i, 1.592-0i, 1.50-0.05i, 1.50-0.1i, 1.50-0.5i, and 1.95-0.66i. The counting efficiency differs from 100% because of statistical effects: photoelectron ...
متن کاملThe effect and correction of aerosol forward scattering on retrieval of aerosol optical depth from Sun photometer measurements
[1] The Sun photometer is widely used to retrieve aerosol optical depth (AOD). In this study, the effect of atmospheric forward scattering on the measurement of direct solar irradiance is analyzed. In most cases, this effect can be safely neglected. However, in the case of heavy dust loading, errors in AOD derived from Sun photometer measurements can be significant which warrants a correction o...
متن کاملgradual erasure of subjectivity: a study of samuel beckett’s trilogy in the light of postmodernism
ساموئل بکت بیشتر از هر نویسنده دیگری در نیم? دوم قرن بیستم با گفتارش زمان? ما را به آستان? از هم پاشیدگی کشانده است، آستانه ای که در آن مدرنیته با سرانجام گریزان اما غیرقابل اجتناب خود مواجه می شود. در این تحقیق روی مفهوم فردیت و محو آن در دوران پسامدرن تاکید شده و در طی آن سعی شده است که فردیت مدرن و پسامدرن در رمان های سه گانه بکت بررسی گردد. تحقیق حاضر یک بررسی کتابخانه ای و کیفی بر روی سه ر...
15 صفحه اولSerum ionised calcium concentration: measurement versus calculation.
Four hundred and eighteen measurements of serum ionised calcium, total calcium, and protein concentrations were made from 47 normal volunteers, 104 patients with chronic renal failure (33 being treated conservatively and 71 with regular haemodialysis), and 83 renal transplant recipients. The serum ionised calcium concentration was measured with an Orion SS-20 meter and calculated from the total...
