This research explores how fluid flow, structural movement, and sound interact in an elastic baffle system. Using a numerical approach based on the finite element method, the study analyzes how noise and vibrations change with different baffle configurations. The findings reveal that shortening the baffle by half reduces noise transmission by 9%, while

CFD Study of a New Annular Lift Fan Configuration with High Lift Efficiency
A new annular lift fan configuration that has very high lift efficiency is explored by using a numerical scheme. The inlet lip radius and diffuser angle are maximized by semicircle duct walls and the location of the lift fan is moved from the throat to ...

After collecting Musa paradisiaca leaves, some were dried and others were used to produce aqueous extracts. The extracts and powders were characterized and then administered to rats made anaemic by PHZ. After 14 days of administration of the two samples, the rats were euthanized and it was observed that after 9 days of treatment, the aqueous extract ...

Large scale wind tunnel investigation of a semispan wing equipped with an externally-blown jet flap [PDF]
A wind tunnel investigation was made of the aerodynamic characteristics of a 14.5 foot semispan, externally-blown jet flap model. The model was equipped with a single 30-inch diameter, ducted fan with a 1.03 pressure ratio.

Lifting-line theory for subsonic axial compressor rotors [PDF]
July 1972Includes bibliographical references (leaf 25)The three-dimensional compressible vortex theory of an axial compressor rotor or ducted fan is extended by relating blade loading to blade geometry in the lifting-line approximation.

The role of the host—Neutrophil biology
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
