Asbestos and Airflow Limitation

Journal of Occupational and Environmental Medicine, 1986
To assess the effect of asbestos on the airways, researchers studied 45 shipyard workers who were lifelong nonsmokers and had asbestos-related abnormalities seen on their chest roentgenograms. Patients with interstitial lung disease, bronchial asthma prior to asbestos exposure, recurrent pneumonias, or significant cardiovascular disease were excluded ...

Visual Exploration of Nasal Airflow

IEEE Transactions on Visualization and Computer Graphics, 2009
Rhinologists are often faced with the challenge of assessing nasal breathing from a functional point of view to derive effective therapeutic interventions. While the complex nasal anatomy can be revealed by visual inspection and medical imaging, only vague information is available regarding the nasal airflow itself: Rhinomanometry delivers rather ...

Investigation on Underhood Airflow Management - Effect of Airflow Statistics

SAE Technical Paper Series, 2018
<div class="section abstract"><div class="htmlview paragraph">The objective of this work is to examine the suitability of cooling airflow non-uniformity on radiator frontal surface as a factor to evaluate three attributes: airflow distribution, front fascia geometry and deterioration in heat rejection. In literature, the effect of front end

Laminar airflow and mixing ventilation: Which is better for operating room airflow distribution near an orthopedic surgical patient?

American Journal of Infection Control, 2019
BACKGROUND There has been little research on the performance of laminar airflow (LAF) and mixing ventilation (MV) systems regarding clean airflow distribution near a surgical patient in operating rooms (ORs).

The Numerical Simulation of Swirling Airflow Field for Different Swirling Airflow Head in Swirling Airflow Finishing

Applied Mechanics and Materials, 2014
The key of swirling airflow finishing is how to generate the swirling airflow. In the paper, three swirling airflow head are discussed according the manners of tangential inflow. By means of FLUENT, the general software of CFD, the swirling airflow field from different airflow head is simulated. The simulation results are shown by the flow line graphs,

Measurement of Airflow in Speech

Journal of Speech and Hearing Research, 1977
It has been shown previously that a mask-type wire screen pneumotachograph can be constructed with a time resolution of % msec. In this paper it is shown that with careful design a resolution of about % msec can be achieved. The various factors involved in optimizing such a mask are described.

Pathology of chronic airflow obstruction

Chest, 1990
Classification of chronic airflow obstruction may be based on the site of the obstructing lesions. It is seldom that only one type of lesion is present, but one may often dominate. In chronic bronchitis, the major disease of large airways, chronic mucus hypersecretion, is reflected by an increase in size of bronchial mucous glands. This may be a factor
