Debris Flow Debris Flow Detection by Combinations of LVP Sensors and Wires: Examples in Sakura-jima Island in Japan

Journal of the Civil Engineering Forum
Various kinds of sensors for debris flows detection have been proposed such as wire sensor, acceleration sensor, and so on. In Europe, a geophone that is based on a vibration meter is usually used though the applicability is not confirmed for debris ...

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

Nonlinear Modified Flood Method for Calculating the Debris-flow Peak Discharge in Wenchuan Earthquake Region

工程科学与技术, 2010
:Mitigating debris-flow hazards is a great challenge in a period after Wenchuan Earthquake. Because of the complexity of debris supply and formation, the debris-flow discharge with respect to flood discharge was amplified in runoff, converging and moving

Evolution of Debris‐Flow Initiation Mechanisms and Sediment Sources During a Sequence of Postwildfire Rainstorms

Journal of Geophysical Research - Earth Surface, 2019
Wildfire alters vegetation cover and soil hydrologic properties, substantially increasing the likelihood of debris flows in steep watersheds. Our understanding of initiation mechanisms of postwildfire debris flows is limited, in part, by a lack of direct

Sacrificial‐Layer‐Assisted Heat‐Affected‐Zone Suppression in Laser Patterning of PET for High‐Performance Flexible Devices

Advanced Functional Materials, EarlyView.
A removable sacrificial polymer layer engineers the thermal boundary condition during nanosecond laser ablation of PET, suppressing heat‐affected‐zone formation without relying on costly ultrafast lasers. This strategy enables deep, high‐aspect‐ratio trenches with no detectable heat‐affected zone, templating silver‐filled mesh electrodes with record ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Experimental study on the impact load characteristics of a single-row pile dam against debris flow

Geomatics, Natural Hazards & Risk
A single-row pile dam is a type of rigid debris flow barrier structure. In order to reveal the mutual interaction effects between debris flow and a single-row pile dam and the distribution law of debris flow impact forces, an analysis of the correlation ...

Role of bank erosion on the unsteady dynamics of debris flow motion

Shui kexue jinzhan, 2018
Debris flow as non-Newtonian fluid has a large yield stress and moved unsteadily. Many models have been established to study the impact of erosion on the unsteady motion, but most of the models were studied the role of the bottom erosion and dam break on

Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells

Advanced Functional Materials, EarlyView.
In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Morphological characteristics and conditions of drainage basins contributing to the formation of debris flow fans: an examination of regions with different rock strength using decision tree analysis [PDF]

Natural Hazards and Earth System Sciences
Debris flows cause severe disasters that can result in human casualties and the collapse of houses. The establishment of early warning systems in basins with high debris flow risks is needed to reduce the negative impacts of debris flow disasters ...
