Reconstructing the impact of human activities in a NW Iberian Roman mining landscape for the last 2500 years [PDF]

, 2014
This article was made available through the Brunel Open Access Publishing Fund.Little is known about the impact of human activities during Roman times on NW Iberian mining landscapes beyond the geomorphological transformations brought about by the use of

A Novel Anatomical Description of the Normal Terminal Fibular Artery and the Terminal Fibular Window: Radiological Findings and Surgical Implications

Clinical Anatomy, EarlyView.
ABSTRACT A novel anatomical description and radiological finding, related to the anatomical course of the terminal fibular artery (FibA) was recently reported. In the article, the authors found the terminal FibA to change its course, from being posterior and medial to the fibula to surface anteriorly and laterally before residing below the tibiofibular

Syntheses and Properties of Pentafluoroethylplumbanes in the Oxidation States +II, +III, and +IV

Chemistry – A European Journal, EarlyView.
Syntheses of pentafluoroethyl substituted plumbanes in the formal oxidation states +II, +III, and +IV are reported. The compounds were characterized by multinuclear NMR spectroscopy, including 207Pb NMR spectroscopy, mass spectrometry and single‐crystal x‐ray diffraction experiments. ABSTRACT Mono‐, bis‐, and tris(pentafluoroethyl)plumbanes of the type

Photoinduced ROS Production by Poly(3‐hexylthiophene) (P3HT) is due to Autoxidation Rather Than Catalysis

Chemistry – A European Journal, EarlyView.
P3HT is widely treated as a photocatalyst that generates ROS under light. We show otherwise: ROS production comes at the expense of the polymer itself. Photoexcited P3HT acts as a self‐sacrificial photosubstrate, undergoing irreversible autoxidation during light‐driven oxygen reduction—a distinction critical for interpreting its behavior in emerging ...

Development of a Mechanically Regenerating Desublimator for Freeze‐Drying Systems in the Food Industry

Chemie Ingenieur Technik, EarlyView.
Thermal defrosting limits desublimator efficiency in freeze‐drying. This review and case study compares thermal versus mechanical regeneration, links frost properties and external heat transfer to energy demand, and summarizes pilot‐scale scraping results enabling single‐unit, continuous lyophilization.

Total Roman Domination Edge-Supercritical and Edge-Removal-Supercritical Graphs [PDF]

, 2020
A total Roman dominating function on a graph G is a function f : V (G) → {0, 1, 2} such that every vertex v with f(v) = 0 is adjacent to some vertex u with f(u) = 2, and the subgraph of G induced by the set of vertices w such that f(w) > 0 has no ...

Extended batch adsorber analogue model (e‐BAAM) for rapid evaluation of CO2 capture pressure swing adsorption cycles

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This work presents a simplified extended‐batch adsorber analogue model (e‐BAAM) to quantify key performance metrics such as purity, recovery, and energy trends for various pressure swing adsorption (PSA) process cycles for CO2$$ {\mathrm{CO}}_2 $$ capture.

Variants of the Domination Number for Flower Snarks [PDF]

, 2023
We consider the flower snarks, a widely studied infinite family of 3--regular graphs. For the Flower snark $J_n$ on $4n$ vertices, it is trivial to show that the domination number of $J_n$ is equal to $n$. However, results are more difficult to determine

One century of teaching, research, and innovation in chemical engineering in Mexico: The role of chemical engineering in the background and future of polymer science and industrial production in Mexico

The Canadian Journal of Chemical Engineering, EarlyView.
Timeline of key academic milestones and individuals that shaped chemical engineering at FQ‐UNAM and in Mexico. Abstract One hundred years after the beginning of the teaching of Chemical Engineering in Mexico, which started in 1925 in the former National School of Chemical Sciences, currently Faculty of Chemistry (FQ) at National Autonomous University ...
