Beluga (Delphinapterus leucas) Novel Bubble Helix Play Behavior [PDF]
Animal Behavior and Cognition, 2014 Cetaceans demonstrate considerable ingenuity in their play with bubbles. Both wild and captive cetaceans have been reported to manipulate self-produced bubbles (Delfour & Aulagnier, 1997; Gewalt, 1989; Kuczaj, Makecha, Trone, Paulos, & Ramos, 2006 ...

Experimental Economics, 2017 Smith et al. (1988) reported large bubbles and crashes in experimental asset markets, a result that has been replicated by a large literature. Here we test whether the occurrence of bubbles depends on the experimental subjects' cognitive sophistication.

Effect of viscosity on the dynamics of a non-equilibrium bubble in free-field and near a free-surface [PDF]
Experimental Thermal and Fluid Science, Volume 116, 1 August 2020,
110113, 2023 The effect of viscosity on the behaviour of a non-equilibrium bubble is investigated experimentally, in two scenarios; firstly, when the bubble is generated in the bulk of the fluid (termed as ``free-field'' bubble) and secondly when the bubble is generated near a free-surface (termed as ``free-surface'' bubble).

PROCEDURE FOR DETERMINING HYDRAULIC JET BARBOTTER RESISTANCE FOR COLLECTING FINE DUST
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2020 North Caucasian Institute of Mining and Metallurgy (State Technological University) has developed a design of a jet bubbler which is based on the patented design of the device main unit – a distribution plate, which allows to implement a foam mode in the

SSRN Electronic Journal, 2014 We introduce noisy information in the determination of stock prices. Agents receive a noisy signal about the structural shock driving future dividend variations. The resulting equilibrium stock price includes a transitory component { the \noise bubble" { which can be responsible for boom and bust episodes unrelated to economic fundamentals.

The role of the bubble–bubble interaction on radial pulsations of bubbles
Ultrasonics Sonochemistry, 2021 Using a model that with or without considering the interaction between bubbles through the radiated pressure waves, numerical simulations of cavitation bubbles have been performed in order to study the effect of the bubble-bubble interaction on radial pulsations of bubbles. Comparing the results obtained by with or without considering the bubble-bubble

From social distancing to social containment
Medicine Anthropology Theory, 2020 This essay develops an anthropological critique of ‘social distancing’. While the 2020 coronavirus pandemic requires us to reconfigure established forms of sociality, distancing regimes such as ‘lockdowns’ can profoundly disrupt the provision of care and

Frontiers in Physiology, 2021 We suggested that the nanobubbles, which appear at the active hydrophobic spots (AHSs) at the luminal aspect of the blood vessels, are the gas micronuclei from which the decompression bubbles evolve and the endothelial injury during the decompression is ...

Theoretical study on bubble dynamics under hybrid-boundary and multi-bubble conditions using the unified equation [PDF]
, 2023 This paper aims to use the unified bubble dynamics equation to investigate bubble behavior in complex scenarios involving hybrid free surface/wall boundaries and interactions between multiple bubbles. The effect of singularity movement on the unified equation's form is analyzed after deriving the bubble pulsation equation using a moving point source ...
