The term "siphon" is used for a number of structures in human and animal anatomy, either because flowing liquids are involved or because the structure is shaped like a siphon, but in which no actual siphon effect is occurring: see Siphon (disambiguation). There has been a debate if whether the siphon mechanism plays a role in blood circulation ...
The chain fountain phenomenon, also known as the self-siphoning beads, Mould effect, or Newton beads is a physical phenomenon observed with a chain placed inside a jar. One end of the chain is pulled from the jar and is allowed to fall under the influence of gravity .
As the water level reaches the high point of the tube, it creates a siphon effect, sucking water out of the chamber. Eventually air rushes into the tube and breaks the siphon, stopping the flow if there is no other source feeding the spring, or reducing the flow if there is a continuous flow from another non-siphon source.

A picture of a bottle with a gas inlet is shown in the works of Mariotte, [1] but this construction was made to show the effect of outside pressure on mercury level inside the bottle. It further misses a siphon or an outlet for the liquid.
Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
Phạm Hùng, Secretary of the Central Office of South Vietnam (COSVN), outlined the requirements about the ordered anthem: [1] [2] The anthem's targets were all of the population of South Vietnam. The anthem had to call for the armed insurrection against the US-backed Saigon regime and the unification of Vietnam as a whole.
Vietnam has abundant surface and ground water resources. [11] Nevertheless, local shortages can occur during the dry season. For example, the basins of the Dong Nai River in South Vietnam, the Southeast River Cluster, Ma River in North Central Vietnam, Kone River and Huong River are expected to be at risk of exceeding projected water needs in ...
The Vietnam War effectively began with the start of the North Vietnamese backed VC insurgency in 1959/60 and the U.S. increased its military aid and advisory support to South Vietnam in response. [3]: 119–20 With the worsening military and political situation in South Vietnam, the U.S. increasingly became directly involved in the conflict.
