Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Onset of Habitable Conditions on the Hadean Earth Set by Feedback between Tides and Greenhouse Forcing

open access: yesThe Planetary Science Journal
In the aftermath of the Moon-forming giant impact, the Hadean Earth’s mantle and surface crystallized from a global magma ocean blanketed by a dense volatile-rich atmosphere.

The Effects of Tidal Forcing on Nutrient Fluxes in the Tidal, Freshwater James River Estuary, VA

open access: yes, 2016
A 12-month study (January to December 2015) focused on the effects of tidal forcing on nutrient fluxes in the tidal, freshwater segment of the James River Estuary (JRE). Discrete sampling of nutrient chemistry and continuous monitoring of tidal discharge

Three‐dimensional geometric morphometric analysis of diaphragmatic dome motion in COPD patients

open access: yesThe Anatomical Record, EarlyView.
Abstract Diaphragmatic dysfunction is a hallmark of chronic obstructive pulmonary disease (COPD), especially in emphysema, where hyperinflation alters diaphragm geometry and impairs inspiratory mechanics. However, quantitative three‐dimensional (3D) assessments of diaphragmatic dome shape and motion across COPD phenotypes are limited.

A Nested-Grid Ocean Circulation Model for Simulating Three-Dimensional Circulation and Hydrography over Canadian Atlantic Coastal Waters

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2010
A one-way nested-grid coastal ocean circulation modeling system was developed for Canadian Atlantic coastal waters based on an operational prototype shelf circulation forecast system known as Dalcoast3 and a high-resolution coastal circulation model ...

Relativistic tidal forces

open access: yesThe Astrophysical Journal, 1983
The post-Newtonian, relativistic (1/c/sup 2/) tidal force is calculated within the general PPN framework of all metric theories of gravity. There are no relativistic tides in general relativity, but they are generally nonzero in other metric theories of gravity, including scalar-tensor theories.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Periodic tidal forcing and seismic response in the diverse tectonic settings of the Andaman–Sumatra subduction zone, Sunda Arc

open access: yesFrontiers in Earth Science
Tidal modulation of seismicity is globally reported in fluid-rich environments of hydrothermal systems, particularly in oceanic or coastal settings. Specifically, the short-period and high-amplitude stress variations caused by ocean tidal loading within ...

Observations and modelling of the variability of the Solent-Southampton Water estuarine system

open access: yes, 2008
Understanding the effect of physical forcing on estuarine functioning is of major importance to determine the rate of exchange of water, sediments, pollutants and nutrients between the continent and the ocean.
