TOTAL PHYSICAL RESPONSE AS AN INTEGRAL FACTOR FOR TEACHING ENGLISH VOCABULARY TO PRE-ADOLESCENT LEARNERS

Društvene i Humanističke Studije, 2020
The primary concern of this paper was the vocabulary acquisition of young, pre-adolescent, learners through the use of TPR (Total Physical Response). The paper attempted to investigate whether pre-adolescent learners (sixteen students who participated as

Valorization of paper sludge for bioethanol and biogas production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study evaluated the physicochemical properties and bioenergy potential of three distinct paper sludges: virgin pulp sludge (VP‐PS), corrugated cardboard sludge (CR‐PS), and tissue and printing paper sludge (TPR‐PS). From the experimental runs, VP‐PS exhibited the highest ethanol yield (46.8 ± 3.7 g L−1, 87.4% conversion), which can be ...

More Than 10 Years on: Does a State‐of‐the‐Art Review and Synthesis Offer New Frameworks to Guide Future Design for Remanufacturing Research?

Business Strategy and the Environment, EarlyView.
ABSTRACT There is strong evidence that design for remanufacturing (DfRem) can reduce initial‐design carbon emissions by up to 30%, and that product design can critically affect remanufacturing feasibility, yet academic adoption of DfRem remains limited.

Decoding Emotional Signatures of Ethical Ads: An Analysis of Actor‐Viewer Synchrony

Journal of Consumer Behaviour, EarlyView.
ABSTRACT We examine whether ethical advertisements differ from conventional ads in their on‐screen emotional signatures and whether those signatures transfer to actor‐viewer synchrony. Study 1 analyses 138 professionally produced YouTube ads using Automated Facial Expression Recognition (AFER) and Convolutional Neural Networks (CNN) to quantify actor ...

Simultaneous Photoactivation of Copper and Ti‐Doped CeO2−x Enables Optimal Acceleration of the RWGS Reaction

Carbon Energy, EarlyView.
A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

Entropy‐Controlled Exsolution of Highly Dispersed Nickel‐Based Active Metals From Spinel Oxide via Optimizing Metal‐Support Interaction for Dry Reforming of Methane

Carbon Energy, EarlyView.
The incorporation of transition‐metal elements into spinel oxides results in enhanced configurational entropy and increased metal‐support interaction, which continuously modulate the exsolution of nickel‐based active metal. The highly dispersed nickel‐based metal catalyst, formed through the entropy‐controlled strategy, demonstrates remarkable activity

Boosting C=O Bond Scissoring Over a Pyridinic Nitrogen‐Modified Cu–MoC Interface for High‐Efficiency CO2 Hydrogenation to CO

Carbon Energy, EarlyView.
ABSTRACT Reverse water‐gas shift (RWGS) reaction‐aided sustainable CO2 conversion has emerged as one promising and effective approach for simultaneously mitigating climate change and solidifying energy security. Molybdenum carbide‐based catalysts demonstrate excellent selectivity for sustainably transforming CO2 into CO product, but harsh carburization
