Single-particle levitation system for automated study of homogeneous solute nucleation [PDF]

open access: yes, 2006
We present an instrument that addresses two critical requirements for quantitative measurements of the homogeneous crystal nucleation rate in supersaturated aqueous solution. First, the need to perform repeated measurements of nucleation incubation times

Controls on spatial and temporal variations in sand delivery to salmonid spawning riffles [PDF]

open access: yes, 2017
Fine sediment infiltration into gravel interstices is known to be detrimental to incubating salmonid embryos. Infiltration into spawning riffles can show large spatial variations at the scale of a morphological unit and over time, with significant ...

Between the Atolls: Sea Turtle Nesting in the Maldives from 2018 to 2024

open access: yesAnimals
Sea turtles are a vital part of the marine ecosystem in the Maldives. While five species have been recorded in-water in the country, only two have been historically known to nest here: hawksbills and greens. In this study, we present cumulative data from
