The aerodynamic characteristics of cat allergen

Clinical & Experimental Allergy, 1993
SummaryTo further characterize airborne cat allergen and a newly established cat challenge facility, airborne Fel d I levels and particle size distributions were studied in both the cat challenge room and home environments under different conditions of ventilation and physical activity.

Analysis on Aerodynamic Characteristics of a Paraglider Airfoil

Aerotecnica Missili & Spazio, 2016
Paraglider sail (canopy) consists of a series of flexible boxes pressurized by special openings located at the leading edge, in the region near to the front stagnation point. Therefore, in order to avoid the deflation of the wing, the pressure inside the sail must remain above a certain threshold.

Aerodynamic characteristics of trills

The Journal of the Acoustical Society of America, 1998
What are the aerodynamic conditions required for trills? To find out we had two subjects produce steady-state voiced, voiceless, and ejective alveolar trills. The backpressure during trills was intermittently bled with a tube of varying diameter (and thus impedance) inserted in the speaker’s mouth via the buccal sulcus and gap behind the back molars ...

The Aerodynamic Characteristics of a Microbus

Advanced Materials Research, 2011
This work is focused on the reduction of the aerodynamic resistance of a microbus. The approach is the three dimensional (3-D) numerical simulation. The RNG k–ε turbulence models are adopted in the computation. Based on the model of SC6350 Chang’an microbus and the improved rear shape, the aerodynamic characteristics of both models at different speeds ...

Acoustic and Aerodynamic Characteristics of Choral Singers

Journal of Voice, 2019
The study aimed to investigate and compare the acoustic and aerodynamic characteristics of choral singers and nonsingers.Twenty choral singers and 20 nonsingers in the age range of 20-30 years with no vocal pathology participated in the study. For acoustic analysis, the voice sample was recorded and analyzed using Praat software (Phonetic Sciences ...

Aerodynamic characteristic of a canard guided rocket

International Journal of Modeling, Simulation, and Scientific Computing, 2017
The computational fluid dynamics (CFD) numerical simulation was used to investigate the aerodynamic characteristic of a canard guided rocket based on the technology of high quality point-to-point multi-block structured grid. The results of numerical simulation and experiments showed that the method is highly credible, and the method could be used to ...

Aerodynamic Characteristics of the Wings and Body of a Dragonfly

Journal of Experimental Biology, 1996
ABSTRACT The aerodynamic characteristics of the wings and body of a dragonfly and of artificial wing models were studied by conducting two types of wind-tunnel tests and a number of free-flight tests of gliders made using dragonfly wings. The results were consistent between these different tests.

Aerodynamic Characteristics of Tracheostomy Speaking Valves

Journal of Speech, Language, and Hearing Research, 1993
Pressure-flow characteristics were determined for four different one-way valves used for speech production in the patient who has had a tracheotomy. Each valve was tested at steady-state flow rates of 150, 250, 350, and 450 ml/sec in isolation and attached to a tracheostomy tube. Results indicated significant differences in resistance among the valves.
