Oceanic Plastic Trash Conveys Disease To Coral Reefs（图）
Oceanic Plastic Trash Conveys Disease Coral Reefs
2018/2/1
For coral reefs, the threat of climate change and bleaching are bad enough. An international research group led by Cornell University has found that plastic trash – ubiquitous throughout the world’s o...
If it smells like food, and looks like food, it must be food, right?Not in the case of ocean-faring birds that are sometimes found with bellies full of plastic. But very little research examines ...
The mechanics of Campi Flegrei unrests as related to plastic behaviour of the caldera borders
Campi Flegrei unrest machanism caldera structure discontinuities plastic effects
2015/10/8
We present here a model which explains the mechanism of generation of unrest episodes at Campi Flegrei caldera from a mechanical point of view. The mechanism involves the effects of plastic zones at t...
Green turtles are swallowing plastic at twice the rate they did 25 years ago, according to a University of Queensland study.

Mapping the initiation of plastic deformation in nanoindentation
plastic deformation nanoindentation
2010/11/17
Under the inhomogenous stress field set up by nanoindentation, the smaller the extent of the stress field the greater the yield pressure. When the specimen contains a thin layer of softer material, th...
Assessment of Extruded Wood Plastic Composite Decking Materials
Extrusion Flexural Property High Density Polyethylene (HDPE) Recovered Milk Bottles Recycling Saw Dust Saw Dust-Recovered HDPE Composite Decking
2011/12/22
Wastes such as saw dust (Pinus Radiata) and milk bottles (High Density Polyethylene - HDPE) are available in abundance. Composite decking materials, consisting of different weight percentages (60%, 70...
Development of crystallographic preferred orientation and microstructure during plastic deformation of natural coarse-grained quartz veins
Development of crystallographic preferred orientation and microstructure plastic deformation natural coarse-grained quartz veins
2014/5/20
The microstructure and crystallographic preferred orientation (CPO) of quartz were quantified in 17 samples of natural monomineralic tabular veins. The veins opened and were= deformed, up to shear str...
Study of temperature variation in human peripheral region during wound healing process due to plastic surgery
Wound healing Finite element method
2010/9/17
In this paper, investigations are made to analyze the human body temperature during wound healing process due to surgery. Wound is considered after the skin graft. Skin graft is a technique used in pl...
HANDS-ON OCEANOGRAPHY——Sorting Out Sediment Grain Size and Plastic Pollution
Beach erosion beach plastic pollution sediment particle size the buoyancy material density sand
2015/7/6
This activity familiarizes students with beach erosion, beach health, and the pervasive nature of plastic pollution. Students use measurements of sediment grain size and the buoyancy and density of ma...
Shearing tests with a thin layer of clay between filter slabs render possible large and cyclic deformations with drainage. In the pressure range of 100 kPa they serve to validated visco-hypoplastic co...
The impacts of future climate change and sulphur emission reductions on acidification recovery at Plastic Lake, Ontario
climate change Plastic Lake sulphur emission
2009/4/29
Climate-induced drought events have a significant influence on sulphate export from forested catchments in central Ontario, subsequently delaying the recovery of surface waters from acidification. In ...
Existence of Regular Solutions for a One-Dimensional Simplified Perfect-Plastic Problem with a Unilateral Gradient Constraint
Regular Solutions Unilateral Gradient Constraint One-Dimensional Simplified Perfect-Plastic Problem
2009/2/5
This work is devoted to the study of the existence of "regular" solutions for a one-dimensional problem with unilateral constrained gradient in Perfect-Plasticity.
The particularity of this problem ...
The large-scale two-dimensional rheology of a sea ice pack arises from the local contact forces between adjacent does in convergence. It is conventionally modeled by a viscous-plastic constitutive rel...
Asymptotic Stability of the Viscous–Plastic Sea Ice Rheology
Asymptotic Stability Viscous–Plastic Sea Ice Rheology
2008/12/3
The stability of the viscous–plastic rheology used extensively to model the dynamics of large–scale sea ice covers is studied. Using energy methods, it is shown that on a bounded domain, the viscous–p...
