To determine the effects of atmospheric aerosols on the radiative heating of the earth-atmosphere system, the radiative transfer equation is solved analytically in the two-stream approximation. It is found that the sign of the heating is independent of optical thickness of an aerosol layer and the amount of heating approaches a finite limit with ...

Field-deployable, high-resolution, time-of-flight aerosol mass spectrometer.
Analytical Chemistry, 2006The development of a new high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS) is reported. The high-resolution capabilities of this instrument allow the direct separation of most ions from inorganic and organic species at the same ...

The success of aerosol therapy depends upon the delivery of ample amounts of the drug to appropriate sites in the lung with minimal side effects. Successful aerosol therapy delivery systems must provide sufficient respirable particles or droplets, with minimal loss of the drug. Ultimately, the patient must be able to use the device easily, maintain it,

Aerosol sampler for analysis of fine and ultrafine aerosols
Analytica Chimica Acta, 2018A new aerosol sampler based on the original version of Aerosol Counterflow Two-Jets Unit (ACTJU) is described. The ACTJU collector, connected with a water-based Condensation Growth Unit (CGU) placed upstream of the ACTJU, accomplished the quantitative collection of fine and ultrafine aerosol particles down to a few nanometers in diameter.

Bronchiolitis is a common illness of the lower respiratory tract affecting infants that has considerable short and long-term morbidity and occasional mortality. It is the commonest cause of hospitalization for respiratory infection in early childhood, and the seasonal nature of the illness places considerable strain on health care resources during the ...

This overview introduces atmospheric aerosol, including basic definitions and properties. Types of aerosols, sources, transformation processes and sinks are described. The spatial distribution of atmospheric aerosol is discussed on the basis of field observations conducted at the DLR Institute of Atmospheric Physics.

Aerosol medications are used commonly in mechanically ventilated patients. Several classes of drugs with different properties and indications may be given by inhalation. In all cases, inhaled therapy's main advantage over the systemic route is that, for a given therapeutic response, the drug dose is several-fold lower, whereas systemic absorption is ...

Aerosols Climatology of Stratospheric Aerosols
Herein, we discuss the significance and measurement of stratospheric aerosols. Stratospheric aerosols play an important role in the chemistry and climate. In the past several decades, their levels have been highly variable and primarily controlled by a series of low latitude eruptions.Vernier, Jean-Paul, Berthet, Gwenaël
