After Swan developed the initial balloon tip, Ganz used Fronek's idea and added a small thermistor (temperature probe) about 3 cm behind the tip. 10 ml of saline (0.9% NaCl) under 10 °C or room temperature (not as accurate) is injected into an opening in the right atrium. As this cooler fluid passes the tip thermistor, a very brief drop in the ...
A swan neck flask, also known as a gooseneck flask, is a round-bottom flask with a narrow s-shaped tube as its opening to reduce contact between the inner contents and external environment.

[1]: 26 The model was developed independently by Robert Solow and Trevor Swan in 1956, [2] [3] [note 1] and superseded the Keynesian Harrod–Domar model. Mathematically, the Solow–Swan model is a nonlinear system consisting of a single ordinary differential equation that models the evolution of the per capita stock of capital. Due to its ...
The largest living species, including the mute swan, trumpeter swan, and whooper swan, can reach a length of over 1.5 m (59 in) and weigh over 15 kg (33 lb). Their wingspans can be over 3.1 m (10 ft). [15] Compared to the closely related geese, they are much larger and have proportionally larger feet and necks. [16]

The black swan theory or theory of black swan events is a metaphor that describes an event that comes as a surprise, has a major effect, and is often inappropriately rationalized after the fact with the benefit of hindsight. The term is based on a Latin expression which presumed that black swans did ...
