Investigation of the fluid behavior of asphaltenes and toluene insolubles by high-temperature proton nuclear magnetic resonance and rheometry and their application to visbreaking [PDF]

, 2016
The fluid behavior of asphaltenes at elevated temperatures impacts coke formation in a number of hydrocarbon conversion processes, including visbreaking and delayed coking. In this study, the asphaltenes from a number of sources, namely, a vacuum residue,

Creating Flood Disasters: Environmental Memory and Adaptation in Aotearoa New Zealand

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 2, June 2026.
This article explores three questions. First, why does New Zealand have widespread flooding hazards? Second, why are these persistent, with little seemingly learned from the memory of earlier events? And third, beyond reiterating conventional solutions, what examples of alternatives or adaptations are being developed in different places?

Political Cycles, Electricity Policy, and Mexico's Economy

Latin American Policy, Volume 17, Issue 2, June 2026.
ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Supercritical multicomponent solvent coal extraction [PDF]

, 1983
The yield of organic extract from the supercritical extraction of coal with larger diameter organic solvents such as toluene is increased by use of a minor amount of from 0.1 to 10% by weight of a second solvent such as methanol having a molecular ...

A Method to Estimate Health Effects Based on Error‐Prone Simulated Environmental Exposure: An Application to a Multi‐Country Study on Birthweight and Fine Particulate Matter

GeoHealth, Volume 10, Issue 5, May 2026.
Abstract Earth System Models provide spatiotemporally continuous environmental exposure data but remain underused in environmental epidemiology because of uncertainty from measurement errors. We developed a novel latent‐variable approach to correct for measurement error characterized by spatiotemporal error covariance, which was derived from ...
