Once the selected interval time elapsed, the first lever press resulted in the delivery of one food pellet into the feeding aperture, which served as reinforcement.
The receiver's gaze makes the social request to be fed (mouth aperture) effective at activating a social affordance.
Since high gain must be obtained based on limited feed antenna's aperture, dielectric-loaded horn antenna was designed as the feed of parabolic reflector antenna to receive the power radiated from the object.
It is known that proximity and aperture coupled feeding structures are sensitive to the transverse feed point location.

In contrast, the proposed feeding architecture is very easy to fabricate and it overcomes the alignment difficulties arising from the proximity and aperture coupled feeding structures.
Dome-shaped papillae are commonly present on trematodes tegument surfaces, and they are believed to have a sensory function [71] related to feeding at the oral aperture, pressure detection on the general body surface, and sexual reception around the genital pore [72].
Effectiveness of hydrocyclone separations is highly dependent on their geometrical characteristics such as: chamber dimensions, aperture diameters or feed inlet geometry, for instance.
Using equivalent magnetic and electric currents at the aperture of the feed antenna and employing free space dyadic Green's functions, an optimization was performed for the design of a fan beam shaped reflector, needless of any far-field approximation.
Conversely, we studied the effects of the social request to be fed (i.e. the mouth aperture) on planning of sequences unrelated to feeding directed to inanimate (experiment 2) and animate (experiment 4) final targets.
MASCS consists of a small Cassegrain telescope with 257-mm effective focal length and a 50-mm aperture that simultaneously feeds an UltraViolet and Visible Spectrometer (UVVS) and a Visible and InfraRed Spectrograph (VIRS).
