Probing the Oxidation State of Ocean Worlds with SUDA: Fe (ii) and Fe (iii) in Ice Grains

open access: yesThe Planetary Science Journal
Characterizing the geochemistry of Europa and Enceladus is a key step for astrobiology investigations looking for evidence of life in their subsurface oceans.

Production of Oxidants by Ion Bombardment of Icy Moons in the Outer Solar System

open access: yesAdvances in Astronomy, 2011
Our groups in Brazil, France and Italy have been active, among others in the world, in performing experiments on physical-chemical effects induced by fast ions colliding with solids (frozen gases, carbonaceous and organic materials, silicates, etc.) of ...

Factoring Origin of Life Hypotheses into the Search for Life in the Solar System and Beyond

open access: yesLife, 2020
Two widely-cited alternative hypotheses propose geological localities and biochemical mechanisms for life’s origins. The first states that chemical energy available in submarine hydrothermal vents supported the formation of organic compounds and ...

Review of Saturn’s icy moons following the Cassini mission

open access: yesReports on Progress in Physics, 2018
We review our knowledge of the icy moons of Saturn prior to the Cassini orbital mission, describe the discoveries made by the instrumentation onboard the Cassini spacecraft.

Interlinkages Between Agri‐Food Trade and the SDGs at the Global, Regional and Local Level

open access: yesJournal of International Development, EarlyView.
ABSTRACT This study is a structured review on the interlinkages between agri‐food trade and the SDGs in the environmental, social and economic dimensions to identify any missed opportunities that agri‐food trade could positively impact the SDGs and provide policy guidance for the missed opportunities at the global, regional and national levels. A great

Practitioner Review: Attention‐deficit hyperactivity disorder and autism spectrum disorder – the importance of depression

open access: yesJournal of Child Psychology and Psychiatry, Volume 64, Issue 1, Page 4-15, January 2023., 2023
Young people with neurodevelopmental disorders, such as attention‐deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD), show high rates of mental health problems, of which depression is one of the most common. Given that depression in ASD and ADHD is linked with a range of poor outcomes, knowledge of how clinicians should assess ...

The Occurrence of Permafrost within the Glacial Domain

open access: yesGeosciences, 2020
The occurrence of permafrost within glacial environments has never been comprehensively defined based on scientific evidence, despite its importance in determining how all the components of the cryosphere associate and interact.

A Submersible, Off-Axis Holographic Microscope for Detection of Microbial Motility and Morphology in Aqueous and Icy Environments. [PDF]

open access: yesPLoS ONE, 2016
Sea ice is an analog environment for several of astrobiology's near-term targets: Mars, Europa, Enceladus, and perhaps other Jovian or Saturnian moons.

Crustal Failure on Icy Moons from a Strong Tidal Encounter [PDF]

open access: yes, 2015
Close tidal encounters among large planetesimals and moons should have been more common than grazing or normal impacts. Using a mass spring model within an N-body simulation, we simulate the deformation of the surface of an elastic spherical body caused by a close parabolic tidal encounter with a body that has similar mass as that of the primary body ...

Work Engagement in Agile Teams: Extending Multilevel JD‐R Theory

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT Teams often fail to mobilize their resources effectively, which can undermine team engagement. Prominent work engagement theories, including Job Demands‐Resources (JD‐R) theory, have not accounted for this conceptually. By taking a closer look at how teams can mobilize resources through their use of agile work practices (AWPs), we develop a ...
