QUANTUM SPRING [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2012
In this paper, we will give a short review on quantum spring, which is a Casimir effect from the helix boundary condition that proposed in our earlier works. The Casimir force parallel to the axis of the helix behaves very much like the force on a spring that obeys the Hooke's law when the ratio r of the pitch to the circumference of the helix is ...

Vanishing Springs in Nepalese Mountains: Assessment of Water Sources, Farmers' Perceptions, and Climate Change Adaptation

open access: yesMountain Research and Development, 2017
The Thulokhola watershed of the Nuwakot district in the midhills region of Nepal can be considered typical of climate change-related stresses in the region.

Contribution des zones d'échanges entre eau de surface et eau souterraine à la biodiversité des hydrosystèmes : exemple d'une rivière méditerranéenne, la Cèze

open access: yesPhysio-Géo, 2019
In a close future, Mediterranean rivers will support strong disturbances due to climate changes, with inexorable consequences for their fauna. The invertebrate biodiversity of the Cèze River (South of France) was studied in a karstic area.

Insect jumping springs [PDF]

open access: yesCurrent Biology, 2018
How do some insects jump so quickly? As anyone who has tried to catch a grasshopper or a planthopper knows, many insects can jump very rapidly. A planthopper can accelerate in less than 1 millisecond to a take-off velocity of 5 m s–1, requiring a power output (energy per given time) of tens of thousands of Watts per kilogram of muscle.

A new family of bacterial actin-like proteins regulates cell morphology in a filamentous cyanobacterium

open access: yesmSphere
Actin proteins are common to all domains of life and exhibit ATP-dependent polymerization to form filaments. In bacteria, four families of bacterial actin-like proteins (BALPs) have been identified and characterized.

Loading regimes and designing helical coiled springs for safe fatigue life

open access: yesResearch in Agricultural Engineering, 2005
Springs are loaded by harmonic forces very often. High cycles fatigue damage and failure can be found during its service loading. This paper shortly describes stress concentration factor for helical springs on the inner diameter of the spring wire and ...
