The long-term goal of this project is to predict the radiative properties of the marine atmosphere based on aerosol and cloud properties. OBJECTIVES The objective of the project is to improve our understanding of the role of aerosols in the Marine Boundary Layer and our ability to simulate marine stratocumulus clouds as a function of aerosol properties and the large-scale meterology. APPROACH T...

We investigated the effects of a selective beta(2)-agonist, salbutamol, and of phosphodiesterase type 4 inhibition with 4-(3-butoxy-4-methoxy benzyl)-2-imidazolidinone (Ro-20-1724) on the airway and parenchymal mechanics during steady-state constriction induced by MCh administered as an aerosol or intravenously (iv). The wave-tube technique was used to measure the lung input impedance (ZL) betw...

Formation of new aerosol particles by nucleation and growth is a significant source of aerosols in the atmosphere. New particle formation events usually take place during daytime, but in some locations they have been observed also at night. In the present study we have combined chamber experiments, quantum chemical calculations and aerosol dynamics models to study nocturnal new particle formati...

Particulates that deposit in the acinus region of the lung have the potential to migrate through the alveolar wall and into the blood stream. However, the fluid mechanics governing particle transport to the alveolar wall are not well understood. Many physiological conditions are suspected to influence particle deposition including morphometry of the acinus, expansion and contraction of the alve...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 2009...

Abstract The paper gives an overview of experiments on the study natural fires, carried out by staff Department Physical and Computational Mechanics Faculty Mathematics TSU. A number recommendations for safe conduct are given, requirements measuring equipment its use in conducting firefighting activities indicated. It is noted that early detection it best to allows you estimate size aerosol par...

the present research article highlights the metal (cd, cu, pb, zn and fe)distribution pattern in the rspm generated in different hot spot sites located at kochi, thequeen of arabian sea. these sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...

Contact mechanics is related to the deformation study of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. Contact mechanics gives essential information for the s...
