A PLP‐SEC Investigation of Di(Ethylene Glycol) Methyl Ether Methacrylate Radical Polymerization Propagation Kinetics in Solution

Macromolecular Reaction Engineering, EarlyView.
The propagation rate coefficient of di(ethylene glycol) methyl ether methacrylate exhibits the same temperature dependency but is a factor of 12 higher in aqueous solution compared to bulk. Smaller increases are observed in ethanol and ethanol/water mixtures, with the value of the rate coefficient decreasing as the monomer concentration in solution is ...

Modeling n‐Butyl Acrylate Polymerization using Complementary Modeling Techniques

Macromolecular Reaction Engineering, EarlyView.
Two different simulation methods are used for the radical polymerization of nBA: deterministic in Predici and stochastic with mcPolymer. It has been successfully implemented across a wide temperature range. It turns out that the partially different implementation of chain‐length‐dependent termination and β‐scission are important for obtaining ...

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

Near Surface Geophysics, EarlyView.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Current Insight into Human Ornithine Aminotransferase: A Review

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Human ornithine aminotransferase (hOAT) is a mitochondrial matrix pyridoxal‐5′‐phosphate enzyme (PLP) that catalyzes the reversible transfer of the δ‐amino group of L‐ornithine (L‐Orn) to α‐ketoglutarate (α‐KG) yielding glutamate‐5‐semialdehyde (GSA) and glutamate. GSA is prone to cyclize to Δ1‐pyrroline‐5‐carboxylate.

Influence of Oxygen Contamination on the Genesis of Nonmetallic Inclusions in a Microalloyed Steel

steel research international, EarlyView.
Oxygen contamination during melting of steels strongly affects the evolution of nonmetallic inclusions. Controlled remelting experiments, combined with SEM/EDS analysis and thermodynamic simulations, reveal how reoxidation promotes the transformation of alumina‐based inclusions into complex FeO–MnO oxides and other interactions.

Interactive Videos in Multimodal Listening Assessments: Examining Language Learners' Perspectives

TESOL Quarterly, EarlyView.
Abstract The academic success of international students who speak English as a second language (L2) hinges on their ability to effectively communicate and comprehend information in English, which requires well‐developed listening skills. Given that real‐world listening mostly involves processing both auditory and visual information, incorporating ...

Mapping the effects of specific radiation damage and solvent radiolysis in buffers and crystals with online UV–Vis absorption spectroscopy

Acta Crystallographica Section D, EarlyView.
Radiation‐induced changes during X‐ray crystallographic data collection can compromise concurrent spectroscopic studies. Suitable protocols to detect and identify spectral artefacts from crystallization buffers and cryoprotectants are essential for the reliable analysis of chromophoric ligands in macromolecules.Online UV–Vis absorption spectroscopy is ...

On Burenkov's extension operator preserving Sobolev-Morrey spaces on Lipschitz domains

, 2016
We prove that Burenkov's Extension Operator preserves Sobolev spaces built on general Morrey spaces, including classical Morrey spaces. The analysis concerns bounded and unbounded open sets with Lipschitz boundaries in the n-dimensional Euclidean space ...

Mapping the lineage of prostate tissue ablation medical device predicates for focal therapy of prostate cancer approved via the FDA 510(k) clearance pathway

Surgical Practice, EarlyView.
Abstract Objective Medical devices are reviewed by the US Food and Drug Administration (FDA) for safety and effectiveness. Class II devices can receive 510(k) clearance if they are “substantially equivalent” to an existing predicate device. This process can be repeated iteratively, leading to a lineage of predicates for newly cleared devices.
