Origin and formation of a chondritic xenolith in Krymka (LL3.2, breccia): Indications for a late formation of the accretionary breccia

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.

Comparative Evaluation of Single and Combined Adsorption and Peroxone Processes for Taste and Odour Control in Reservoir Water

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Taste and odour compounds (T&O), particularly 2‐methylisoborneol (2‐MIB) and geosmin, pose persistent challenges in drinking water treatment, as conventional methods often achieve limited removal. This study provides a comparative evaluation of five treatment strategies: activated carbon (AC) adsorption, sulfonic acid‐modified activated carbon

ENABLING PARTIAL UPGRADING IN ALBERTA: A REVIEW OF THE REGULATORY FRAMEWORK AND OPPORTUNITIES FOR IMPROVEMENT

open access: yesThe School of Public Policy Publications, 2019
One of the ways that Alberta can help alleviate its worsening bottleneck in oilexport pipelines is by partially upgrading oil sands bitumen before shipping it to market.

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...

Fatigue and Rutting Performance of FAA and Conventional Asphalt Mixture Systems

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 8, Page 3500-3511, August 2026.
ABSTRACT This study evaluates the laboratory fatigue and rutting performance of two specification‐compliant asphalt mixture systems: an FAA‐compliant airfield mixture designed according to FAA AC 150/5370‐10H and a conventional highway mixture designed according to the Turkish General Directorate of Highways requirements.

Predicting the Solvent Properties of Supercritical Water by Integrating Solubility Parameter Theory and Molecular Force Fields

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 1, July 2026.
The study maps molecular force fields to three‐component solubility parameters (δd, δp, and δhb). Solvent behavior reflects the competition between physical effects and hydrogen‐bond network evolution. Crucially, fluid density determines the absolute magnitude of cohesive interactions, whereas temperature functions as a key variable to selectively ...

Exploratory study on bitumen content determination for foamed bitumen mixes based on porosity and indirect tensile strength

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2017
Optimum bitumen content determination is one of the major aims for foamed bitumen mix design. However, mix design procedures for foamed bitumen mixes are still under development.

Correlating High‐Resolution Terrestrial Organic Carbon Isotope Records Across the Cretaceous‐Paleogene Boundary

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Cretaceous–Paleogene boundary (∼66 million years ago) represents the most recent mass extinction event when an estimated 75% of all species became extinct, including all non‐avian dinosaurs. Here we focus on the stable carbon isotope (δ13C) analysis of coal and coaly sediments across the terrestrial K/Pg boundary from 10 sites, between 42 ...

Dependences of SMA mixture and its bituminous binder properties on bitumen batching system, mixing time and temperature on asphalt mixing plant

open access: yesJournal of Civil Engineering and Management, 2013
Bitumen holds the aggregate in hot mix asphalt (HMA). Without asphalt binder, HMA would simply be crushed stone or gravel. A bitumen batching system (BBS) is comprised of bitumen storage, transportation, weighing and discharge equipment in an asphalt ...
