Noise control by a rotating rod in a rod-airfoil configuration

21st AIAA/CEAS Aeroacoustics Conference, 2015
In the present paper, a rotating cylinder is investigated as a noise reduction technique in the rod-airfoil canonical benchmark. Noise prediction is realized by a 2D hybrid computational aeroacoustics approach. Rotation is introduced to the cylinder at rotational frequencies ranging from 1/32 to 2 times the shedding frequency of the nonrotating case ...

CONTROL OF ROD SHEDDING IN THE FROG RETINA

Neurochemistry International, 1980
In all vertebrate species examined thus far, rod outer segment shedding follows a cyclic pattern in which the outer segment tips are shed shortly after the onset of light. Work in the rat retina suggests that rod shedding may follow a circadian rhythm which is controlled by one or more circadian oscillators.

Control Rod Economics

Nuclear Science and Engineering, 1961
The cost of control rods, which contributes a significant fracion to the total cost of a power reactor core, is discussed as a function of metallurgical composition and reactor endurance. Materials considered include hafnium, Cd5- Inl5-Ag80 alloy, several boron carrying systems, and dispersions of such rare- earth oxides as Eu/sub 2/O/sub 3/, Gd/sub 2 ...

Calibration of Control Rods

Nuclear Science and Engineering, 1957
Two methods for calibrating control rods are presented. A theoretical treatment is given of an oscillating technique and experimental results obtained by this method are compared with those obtaine...

Diurnal control of rod function in the chicken

Visual Neuroscience, 1991
AbstractWe studied rod function in the chicken by recording corneal electroretinograms (ERGs). The following experiments were performed to demonstrate rod function during daytime: (1) determining the dark-adaptation function; (2) measuring the spectral sensitivity by a a–b-wave amplitude criterion in response to monochromatic flickering light of ...

Rod width under control

Nature Microbiology, 2019
The finding that the two cell wall elongation systems of Bacillus subtilis have opposite effects on cell diameter and on the amount of oriented material along the sidewalls elucidates the long-standing question of how cell width is controlled in rod-shaped bacteria.

Standardized Control Rods

Aircraft Engineering and Aerospace Technology, 1939
MASS production methods in the construction of modern aircraft demand far‐reaching standardization of such component parts as can be used in various types of aeroplane. Such standardization has, for instance, been applied to the power plant control rods of the Ju 52 where a unified design of welded steel levers is found together with standardized ...

Development of a Composite Control Rod

Nuclear Science and Engineering, 1958
The scarcity and high cost of hafniuin for use as a reactor control material has lead to the development of a composite control rod of hafnium and B/ sup 10/. The fabrication technique developed involves the use of a wrought hafnium and a 3.5 wt. % B/sup 10/ dispersion in titanium powder.
