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 ...

Survey to assess the economic stability and mental health of households with people receiving enteral and parenteral nutrition

Nutrition in Clinical Practice, EarlyView.
Abstract Background The landscape of nutrition support faces challenges, including rising costs, product shortages, reimbursement gaps, and infusion providers closing. This nationwide survey aimed to describe the perceptions and attitudes related to costs, therapy access, and mental health among households with at least one family member requiring ...

Nutritional status and functions in children with cerebral palsy at different gestational ages

Pediatric Investigation, EarlyView.
The nutritional status of cerebral palsy was significantly associated with their motor, eating and drinking ability, and their ability of daily living in the 28–32‐week and the ≥37‐week gestational age group, whereas in 33–36‐week group, correlation was only observed between the nutritional status and eating and drinking ability.

Pressure‐Decay Kinetic Modeling of Homogeneous Ethylene Polymerization with Et(Ind)2ZrCl2/TIBA‐Borate Catalyst System in a Batch Reactor

Polymer Engineering &Science, EarlyView.
A kinetic model comprising both propagation and deactivation functions was developed for metallocene‐catalyzed ethylene polymerization in a batch reactor. The model predicted polymer yields very close to the experimental ones. The polymer molecular weight increased with ethylene pressure and decreased with temperature.

Hyperspectral species maps and LiDAR‐based structured population models show future forest fire frequency may compromise forest resilience

Remote Sensing in Ecology and Conservation, EarlyView.
Monitoring forest recovery from disturbances at scale requires tracking tree dynamics, yet traditional ground‐based approaches are resource‐intensive. We present a pipeline to parameterize integral projection models (IPMs) using LiDAR data and hyperspectral‐based species maps to assess post‐fire recovery across large, forested areas at the Caribou ...

Classification of tree species and standing dead trees in Boreal forests using UAV‐based RGB, multispectral, and LiDAR point clouds

Remote Sensing in Ecology and Conservation, EarlyView.
We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Perfluorohexanone for Clean Fire Suppression: Mechanisms, System Design, Applications, and Future Directions

Safety Science and Technology, EarlyView.
Driven by halon and high GWP agent phase out, perfluorohexanone is increasingly deployed in enclosures such as data centers, marine machinery spaces, and industrial process lines. This review summarizes application performance, discharge and distribution design, material compatibility, and byproduct control and maps practical gaps for large volume and ...
