Effects of Salinity on Bubble Cloud Characteristics
A laboratory experiment investigates the influence of salinity on the characteristics of bubble clouds in varying saline solutions. Bubble clouds were generated with a water jet. Salinity, surface tension, and water temperature were monitored.

Beluga (Delphinapterus leucas) Novel Bubble Helix Play Behavior [PDF]
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 ...

Current Tracking Adaptive Control of Brushless DC Motors
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Non-biodegradable objects may boost microbial growth in water bodies by harnessing bubbles
Given the ubiquity of bubbles and non-biodegradable wastes in aqueous environments, their transport through bubbles should be widely extant in water bodies. In this study, we investigate the effect of bubble-induced waste transport on microbial growth by

IceCube and HAWC constraints on very-high-energy emission from the Fermi bubbles [PDF]
The nature of the $\gamma$-ray emission from the \emph{Fermi} bubbles is unknown. Both hadronic and leptonic models have been formulated to explain the peculiar $\gamma$-ray signal observed by the Fermi-LAT between 0.1-500~GeV. If this emission continues

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Numerical analysis of bubble growth in a molten steel/(N2,H2) supersaturation system
A water/carbon dioxide system was used to study bubble growth dynamics in a molten steel/(N2,H2) supersaturation system. Bubble nucleation and growth mechanism models in the aqueous solution and the molten steel were respectively established.Bubble ...

Velocity distribution in the boundary layer of a bubble rising with a rectilinear motion
The boundary layer of a bubble is an important factor that determines its rising velocity. But it is generally very thin to simulate using typical interface capturing method, such as volume of fluid method.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Doubly-periodic array of bubbles in a Hele-Shaw cell
Exact solutions are presented for a doubly-periodic array of steadily moving bubbles in a Hele-Shaw cell when surface tension is neglected. It is assumed that the bubbles either are symmetrical with respect to the channel centreline or have fore-and-aft ...
