In conclusion, dental implants protruding into the nasal cavity can cause an alteration to the airflow.
In its defense, Samsung told the station that the battery was a replacement and not a Samsung, and that the company's user guide warns consumers that if their units are covered by bedding or other material, choked-off airflow could cause a fire.
This can cause the airflow through the engine to reverse, with the high-pressure gas in the centre of the engine being violently forced out through the engine intake.
Asthma progression often involves airway remodelling (permanent structural changes in airways), which may cause irreversible airflow obstruction and is associated with poorer clinical outcome among patients with asthma (2).
For example, the SKC biosampler directs airflow via three tangential nozzles to create a swirling airflow that causes a liquid collection medium to swirl along the inside surface of the glass collection chamber, causing nearly 100% collection efficiency for particles over 1 µm and 90% efficiency for 0.5 µm (aerodynamic diameter) particles (Willeke et al., 1998).
The tumour acted as a ball valve to cause severe expiratory airflow obstruction.
Nasal obstruction from a deviated nasal septum may cause turbulent nasal airflow precipitating in dryness and crusting of the nose, frequent nosebleeds, and recurrent sinusitis [7].
A heating appliance such as a far-infrared radiation heater that did not cause airflow could have been employed [11].
The airflow velocities (0.24 1.32 ms−1) caused a pressure drop (9.96 346.23 Pa) across the empty drum.
The wind-catchers – long, rectangular structures that cause airflow from the cooler undergrounds to the main rooms – in old homes are even more intricate than those found in Yazd, in the central desert.
The force required to maintain inflation of the lung and to cause airflow is provided by the chest and diaphragm (the muscular partition between chest and abdomen), which are in turn stretched inward by the pull of the lungs.
