Yelp users can make restaurant reservations in Yelp through Yelp Reservations, a feature initially added in June 2010; in 2021 the service was consolidated with others into "Yelp Guest Manager". [ 101 ] [ 102 ] Yelp's reservation features have been done through SeatMe , which was acquired by Yelp in 2013. [ 55 ]
Molybdenum dioxide is a constituent of "technical molybdenum trioxide" produced during the industrial processing of MoS 2: [4] [5]. 2 MoS 2 + 7 O 2 → 2 MoO 3 + 4 SO 2 MoS 2 + 6 MoO 3 → 7 MoO 2 + 2 SO 2
Vortices are points in 2D fields and lines in 3D fields (as they have codimension two). Integrating the phase of the field around a path enclosing a vortex yields an integer multiple of 2 π. This integer is known as the topological charge, or strength, of the vortex. A hypergeometric-Gaussian mode (HyGG) has an optical vortex in its center ...
Vortec is a trademarked name for a line of gasoline engines for General Motors trucks.The name first appeared in an advertisement for the 1985 model year 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air / fuel atomization. [1]
The vortex is begun by briefly turning on a diffuse heater (83) and electrically driving the turbines (21) as fans. This moves mildly heated air into the vortex arena (2). The air must have only a mild temperature difference because large temperature differences increase mixing with cold ambient air and reduce efficiency.
The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing , of an aircraft as an infinitely thin sheet of discrete vortices to compute lift and induced drag .
A bubble ring, or toroidal bubble, is an underwater vortex ring where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins poloidally as it travels through the water, much like a flexible bracelet might spin when it is rolled on to a person's arm.
