The question of providing the density interface between the coupling halves of the hull underwater-gauge steel coupling designed for repair of the underwater section of pipeline.Stress-strain condition of coupling was calculated by finite elements method.Offered the option of simplifying the design of the coupling and Project Panels reduce the load
The Ivory-billed Woodpecker has long held a special place in the psyche of North foot tube foam American conservation, eliciting unusually colorful prose, even from scientists, as an icon of the wild.The reverence in which it was held did little to slow the habitat loss that led to its apparent extinction 60 years ago.A consequence of the emotion a
A narrow frequency bandwidth of epsilon-near-zero metamaterials limits the use foot tube foam of many optical, microwave, and electronic devices.In this paper, we propose a recipe to broaden the operational bandwidth by employing a structure of properly tailored square frames nested within each other.To illustrate this effect, we derive the effecti
