Comparison of various airflow measurements in symptomatic textile workers.
AIMS To investigate the poorly understood relationship between work-related respiratory symptoms, airway reactivity, across working shift change in forced expiratory volume in 1 s (FEV(1)) and work-related changes in serial peak expiratory flow (sPEF) measures in a group of textile workers. METHODS Fifty-three workers, 34 exposed to cotton dust and 19 to man-made fibre (MMF), were investigate...
متن کاملairflow resistance in walnuts
the harvested walnut has a relatively high moisture content of 30% compared with the safe storage moisture content of 8%. one of the common means of reducing the moisture content is by drying. for design of drying and other aeration systems for agricultural products including walnuts, the relationship between the drop in pressure and airflow velocity must be known. an airflow resistance app...
متن کاملForced expiration: a test for airflow obstruction in horses.
The purpose of this study was to assess whether our method of inducing forced expiration detects small airway obstruction in horses. Parameters derived from forced expiratory flow-volume (FEFV) curves were compared with lung mechanics data obtained during spontaneous breathing in nine healthy horses, in three after histamine challenge, and in two with chronic obstructive pulmonary disease (COPD...
