The behavioral effects of nonnutritive sucking on infants of differential fetal growth

open access: yes, 2012
Newborn infants with differential patterns of fetal growth, as determined by their weight-for-length, typically display behaviors which have been conceptualized as reflecting the integrity of the infant's behavioral organization.

Reverse Engineering and Performance Evaluation of a Pump Impeller Fabricated With Additive Manufacturing

open access: yesChemie Ingenieur Technik, EarlyView.
This study explores the process chain for reverse engineering and additive manufacturing of a water pump impeller in a process plant. Key aspects include digital twin creation, CAD redesign, material certification, Hirtisation postprocessing, and performance testing. Insights highlight iterative design for improved precision and reliability.

Caracterização do comportamento de vitelos em regime intensivo na procura de factores de risco para cross-sucking

open access: yes, 2014
Dissertação de Mestrado Integrado em Medicina VeterináriaEm Portugal, um dos entraves à introdução de crossbreeding nas explorações leiteiras é o cross-sucking. O cross-sucking é a sucção não nutritiva direccionada ao corpo de outro vitelo.

Tunable amylopectin graft copolymers for flocculating and dewatering iron ore tailings

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Polyacrylamide (PAM), the standard flocculant for mining tailings, often produces turbid supernatants and poorly dewatered sediments, limiting water reuse and tailings densification. We synthesized amylopectin‐graft‐poly[(2‐methacryloyloxy)ethyl]trimethylammonium chloride (AP‐g‐PMETAC) copolymers with systematically varied graft frequency (N =

Application of dynamic modelling and model‐based predictive control to enhance a cooling tower

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Model predictive control (MPC) applied to improve the operation of cooling towers. Abstract Model predictive control (MPC) differs from traditional feedback control by making predictions within a time horizon, providing better control actions for the process.

A Simple Regeneration Process Using a CO2‐Switchable‐Polarity Solvent for Cellulose Hydrogels

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The effect of transformation of the anion chemical structure on cellulose solubility by flowing CO2 gas into aqueous pyrrolidinium hydroxide solutions was investigated. The changes in anion structure allowed for the modulation of cellulose solubility in aqueous pyrrolidinium hydroxide solutions, thus establishing a simple and safe cellulose ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an
