Marine plastic debris - a new surface for microbial colonization.

open access: yesEnvironmental Science and Technology, 2020
Plastics become rapidly colonized by microbes when released into marine environments. This microbial community - the Plastisphere - has recently sparked a multitude of scientific enquiries and generated a breadth of knowledge, which we bring together in ...

Debris Thickness of Glaciers in the Everest Area (Nepal Himalaya) Derived from Satellite Imagery Using a Nonlinear Energy Balance Model [PDF]

open access: yes, 2014
Debris thickness is an important characteristic of debris-covered glaciers in the Everest region of the Himalayas. The debris thickness controls the melt rates of the glaciers, which has large implications for hydrologic models, the glaciers' response to

Numerical Modeling of Debris Flows Induced by Dam-Break Using the Smoothed Particle Hydrodynamics (SPH) Method [PDF]

open access: yes, 2020
Dam-break flows may change into debris flows if certain conditions are satisfied, such as abundant loose material and steep slope. These debris flows are typically characterized by high density and can generate strong impact forces. Due to the complexity

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]

open access: yes, 2011
The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

QUANTIFICATION OF ECONOMIC AND SOCIAL RISKS OF DEBRIS FLOWS FOR THE BLACK SEA COASTAL REGION OF THE NORTH CAUCASUS

open access: yesGeography, Environment, Sustainability, 2014
Debris flows are the most frequent and disastrous natural hazards among other exogenic processes at the Black Sea coastal region of the North Caucasus. Numerous debris flow releases are reported every year between Novorossiysk and Krasnaya Polyana.

Distributed Global Debris Thickness Estimates Reveal Debris Significantly Impacts Glacier Mass Balance

open access: yesGeophysical Research Letters, 2021
Supraglacial debris affects glacier mass balance as a thin layer enhances surface melting, while a thick layer reduces it. While many glaciers are debris‐covered, global glacier models do not account for debris because its thickness is unknown.

Development of a Debris Index [PDF]

open access: yes, 2018
Environmental indices for space objects have been proposed to identify good candidates for active debris removal missions and to deal with the licensing process of space objects before their launch. A way to rank the environmental impact of spacecraft may be based on the assessment of how their fragmentations would affect operational satellites.

TREM2 activation on microglia promotes myelin debris clearance and remyelination in a model of multiple sclerosis

open access: yesActa Neuropathologica, 2020
Multiple sclerosis (MS) is an inflammatory, demyelinating, and neurodegenerative disease of the central nervous system (CNS) triggered by autoimmune mechanisms.

Estimation of magnitudes of debris flows in selected torrential watersheds in Slovenia [PDF]

open access: yes, 2006
In this paper the application of different methods for estimation of magnitudes of rainfall-induced debris flows in 18 torrents in the Upper Sava River valley, NW Slovenia, and in 2 torrents in Pohorje, N Slovenia is described. Additional verification of
