Spontaneous Rayleigh-Brillouin scattering of ultraviolet light in nitrogen, dry air, and moist air.
Atmospheric lidar techniques for the measurement of wind, temperature, and optical properties of aerosols rely on the exact knowledge of the spectral line shape of the scattered laser light on molecules. We report on spontaneous Rayleigh-Brillouin scattering measurements in the ultraviolet at a scattering angle of 90 degrees on N(2) and on dry and moist air. The measured line shapes are compare...
متن کاملRevised formula for the density of moist air (CIPM-2007)
Measurements of air density determined gravimetrically and by using the CIPM-81/91 formula, an equation of state, have a relative deviation of 6.4 × 10−5. This difference is consistent with a new determination of the mole fraction of argon xAr carried out in 2002 by the Korea Research Institute of Standards and Science (KRISS) and with recently published results from the LNE. The CIPM equation ...
متن کاملEstimation of Moist Air Thermodynamic Properties using Artificial Neural Network
In this study, the equations obtained non-iteratively are presented for moist air thermodynamic properties as a function of dry-bulb temperature and relative humidity. In this regard, an artificial neural network (ANN) was performed by using MATLAB software. In the ANN, dry-bulb temperature and relative humidity were specified as inputs, and water vapor saturation and partial pressures, wet-bul...
متن کاملAvian infectious laryngotracheitis.
Avian infectious laryngotracheitis (ILT) herpesvirus continues to cause sporadic cases of respiratory disease in chickens world-wide. Sources of transmission of ILT infection are three-fold, namely: chickens with acute upper respiratory tract disease, latently infected 'carrier' fowls which excrete infectious laryngotracheitis virus (ILTV) when stressed, and all fomites (inanimate articles as w...
متن کاملEveryday Practice ACUTE LARYNGOTRACHEITIS
Acute Laryngotracheitis can be defined as subacute viral illness characterized by low grade fever, barking cough, inspiratory stridor and expiratory rhonchi. It is also known as infectious croup. Croup is an old Scottish word for sore throat with harsh breathing. It is seen in children between 3 month to 3 years of age (mean age 18 months)(l). Boys are more frequently affected. It occures more ...
