Estimating changes in ocean ventilation from early 1990s CFC-12 and late 2000s SF6 measurements [PDF]

, 2013
Transient tracer measurements can constrain the rates and pathways of ocean ventilation and act as proxies for biogeochemically relevant gases such as CO2 and oxygen.

Exploring the Interrelationships Among Supply Chain Emissions, Financial Performance, Market Value, and Board Sustainability: An Exploration of the European Landscape

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT National and supranational institutions are establishing emission trading systems and control schemes in an attempt to manage stakeholders' willingness to engage with regulatory systems and reduce greenhouse gas emissions (GHG). Nonetheless, despite the national and supranational focus on carbon neutrality, little research has been centered ...

Rumen methanogenic archaea and their correlation with enteric methane emission in ruminant animals: A systematic review and meta‐analysis

JSFA reports, EarlyView.
Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Age of air from ACE-FTS measurements of sulfur hexafluoride [PDF]

Atmospheric Chemistry and Physics
Climate models predict that the Brewer–Dobson circulation (BDC) will accelerate due to tropospheric warming, leading to a redistribution of trace gases and, consequently, to a change of the radiative properties of the atmosphere.

Sulfur hexafluoride (SF₆) emissions in East Asia determined by inverse modeling [PDF]

Atmospheric Chemistry and Physics, 2014
Sulfur hexafluoride (SF6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global SF6 emission trend, from

Using CFCs and SF6 for groundwater dating : a SWOT analysis [PDF]

, 2010
A knowledge of the residence time of groundwater is of importance in understanding key issues in the evolution of water quality. Chlorofluorocarbons (CFCs) and sulphur hexafluoride (SF6) offer a convenient way of dating waters up to ~60 yrs old.

Rayleigh-Brillouin scattering in SF$_6$ in the kinetic regime

, 2016
Rayleigh-Brillouin spectral profiles are measured with a laser-based scatterometry setup for a 90 degrees scattering angle at a high signal-to-noise ratio (r.m.s. noise below 0.15 \% w.r.t. peak intensity) in sulphur-hexafluoride gas for pressures in the

The late-time development of the Richtmyer–Meshkov instability [PDF]

, 2000
Measurements have been made of the growth by the Richtmyer–Meshkov instability of nominally single-scale perturbations on an air/sulfur hexafluoride (SF6) interface in a large shock tube.

Multiparametric Ultrasound Findings of Testicular Sarcoidosis

Journal of Ultrasound in Medicine, EarlyView.
Objectives To characterize the multiparametric ultrasound (MPUS) features of testicular sarcoidosis, incorporating greyscale, color Doppler ultrasound (CDUS), contrast‐enhanced ultrasound (CEUS), and strain elastography (SE), and to assess their collective diagnostic value.
