On the Shell Structure of Nuclear Bubbles [PDF]
, 1997 We investigate the shell structure of spherical nuclear bubbles in simple phenomenological shell model potentials. The shell correction energies for doubly magic bubbles may be as large as -40 MeV and probably imply a very long lifetime against ...

Blowing bubbles: Dermoscopy of bubble hair
International Journal of Trichology, 2017 Exposing wet hair to high temperatures can create gas bubbles within the hair shaft, leading to brittle, dry hairs in a disorder known as bubble hair abnormality. We present a case of a 61-year-old woman who presented for hair breakage over her crown. She regularly dried her damp hair with a blow dryer.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.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 ...

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials
Advanced Engineering Materials, EarlyView.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

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 ...

Visualization of toner ink adsorption at bubble surfaces [PDF]
, 2006 Flotation deinking involves interactions between inks particles and bubbles surfaces. These interactions are very difficult to observe directly or to quantify in bench-scale experiments or mill operations, making it difficult to evaluate effects of ...
