The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

A new species of jewel‐babbler (Cinclosomatidae: Ptilorrhoa) from the Southern Fold Mountains of Papua New Guinea

Ibis, EarlyView.
Based on distinctive morphological and vocal characters we describe a new species of jewel‐babbler (genus Ptilorrhoa) from the forested karst of the Southern Fold Mountains in Papua New Guinea. The description is based on camera trap data and is presented in accordance with ICZN Declaration 45.

Impact of Oxygenated Additives on Soot Properties during Diesel Combustion

Energies, 2020
Emissions from diesel engines can be limited and potentially decreased by modifying the fuel chemical composition through additive insertion. One class of additives that have shown to be particularly efficient in the reduction of the particulates from ...

Pregnancy shifts endothelial progenitor cell morphology and function: Role of metabolism, pro‐inflammatory cytokines and fetal sex

The Journal of Physiology, EarlyView.
Abstract figure legend We recruited non‐pregnant women (NP), women in early pregnancy (EP) and late pregnancy (LP) for isolation of endothelial colony forming cells (ECFCs) via density gradient centrifugation. Plasma supernatant was collected for analysis of markers of glucose and lipid metabolism (fasting glucose, triglycerides, cholesterol, low ...

δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.

Soot modeling with temperature- and size-based collision efficiency for nucleation and condensation

Applications in Energy and Combustion Science
Temperature- and size-based collision efficiencies for the collision of dimerizing gas-phase species and for the condensation of dimers onto soot particles were estimated based on theoretical principles. These collision efficiencies were then implemented

Effects of Equilibrium and Non‐Equilibrium Adsorption States on the Photoreduction and Isotope Fractionation of Hg(II) in Urban Aerosols

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Mercury (Hg) photoreduction on urban aerosols plays a critical role in atmospheric Hg cycling, yet the effects of the adsorption state on its kinetics and isotopic fractionation remain poorly constrained. This study investigates Hg(II) photoreduction under equilibrium (EAC) and non‐equilibrium adsorption conditions (NAC) using a flow‐through ...
