Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Asphalt and bitumen ageing

European Journal of Science, Innovation and Technology, 2022
The ageing of asphalt and the associated changes in its performance are largely due to the ageing binder it contains. Ageing makes bitumen harder and more brittle. The hardening and embrittlement of the binder has a direct effect on the performance characteristics of the asphalt.

Review of Lab-Accelerated Aging Techniques of Asphalt Mixes

Journal of Engineering
Bitumen aging contributes to main pavement distress due to the changes in rheological, chemical, and physical characteristics of bitumen. Mainly, aging process can be divided into two categories, the first category namely short-term aging takes place ...

A Newly Discovered Tablet‐Making Facility in Nineveh: Insights From Scientific Analysis

Archaeometry, EarlyView.
ABSTRACT This paper addresses the question of tablet technology in the Neo‐Assyrian capital city of Nineveh. Recent excavations in the lower town of Nineveh by the Iraqi–Italian Archaeological Expedition uncovered an exceptional assemblage of more than 200 tablets from an elite residence that appears to have included a scriptorium.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

European Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

Journal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.
