Impact of Weathering on the Chemical Identification of Microplastics From Usual Packaging Polymers in the Marine Environment [PDF]

open access: yes, 2021
[Abstract] Most of the plastics produced worldwide are finally disposed into the environment, most of them being one-use plastic packaging. Once released, plastics may undergone degradation through several agents, such as solar radiation, mechanical ...

Plasma Double Layers at the Boundary Between Venus and the Solar Wind [PDF]

open access: yes, 2020
The solar wind is slowed, deflected, and heated as it encounters Venus’s induced magnetosphere. The importance of kinetic plasma processes to these interactions has not been examined in detail, due to a lack of constraining observations.

Prevalidation of Salivary Biomarkers for Oral Cancer Detection [PDF]

open access: yes, 2012
Background: Oral cancer is the sixth most common cancer with a 5-year survival rate of approximately 60%. Presently, there are no scientifically credible early detection techniques beyond conventional clinical oral examination.

Self-Assembled Nanostructures of Peptide Amphiphiles: Charge Regulation by Size Regulation [PDF]

open access: yes, 2019
Self-assembled nanostructures of peptide amphiphiles (PAs) with molecular structures C16K2 and C16K3 (where C indicates the number of carbon atoms in the alkyl chain and K is the lysine in the head group) were studied by a combination of theoretical ...

Assessment of Automated Crowd Behaviour Analysis Based on Optical Flow [PDF]

open access: yes, 2016
In visual surveillance, camera streams are often used to keep an eye on dense crowds. The examination of this data is mostly done manually by observers. When analysing multiple cameras some assistance is desirable.

Exclusion of soil macrofauna did not affect soil quality but increased crop yields in a sub-humid tropical maize-based system

open access: yes, 2015
Soil macrofauna such as earthworms and termites are involved in key ecosystem functions and thus considered important for sustainable intensification of crop production.

On functional equations leading to exact solutions for standing internal waves [PDF]

open access: yes, 2014
The Dirichlet problem for the wave equation is a classical example of a problem which is ill-posed. Nevertheless, it has been used to model internal waves oscillating harmonically in time, in various situations, standing internal waves amongst them.

Effect of increasing pressure on excess volumes for cavities in TIP4P water [PDF]

open access: yes, 2016
NPT simulation results on excess volumes computed by the direct method are presented for spherical cavities in TIP4P water. The cavity is created by defining an exclusion volume for water-oxygen.
