Advances in Sustainable Production of Bio‐Derived 5‐Alkoxymethylfurfural and Levulinate Esters: A Comprehensive Review

Carbon Energy, EarlyView.
The present review discusses the advancement in the catalytic synthesis of 5‐alkoxymethylfurfural (AMF) and levulinate esters (LEs) from the aspects of catalytic systems, reaction mechanisms, product isolation, and techno‐economic analysis, supplying valuable insights toward future sustainable and efficient manufacture of AMF and LEs. ABSTRACT The huge

A Meta‐Analytic Review of Board Characteristics and Carbon Emission Disclosure: The Moderating Effect of Contextual Factors

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The relationship between board governance and corporate carbon emission disclosure remains persistently inconsistent across the empirical literature, despite decades of accumulated evidence. Drawing on agency, stakeholder, legitimacy, institutional, and upper echelons perspectives within a single analytical framework, we conduct a three‐level ...

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...

Advancing mine pillar design: Evaluating traditional methods and integrating AI for enhanced stability of pillars in the Great Dyke, Zimbabwe

Deep Underground Science and Engineering, EarlyView.
B1 is bord width 1, B2 is bord width 2, L is the pillar length, W is the pillar width, red color and letter A represent the pillars, and white color and number 1 represent excavated areas. Pstress is the average pillar stress; σv is the vertical component of the virgin stress, MPa; and e is the areal extraction ratio. e = B o B o + B P ${\rm{e}}=\frac{{

Basketball Surfaces and Coefficient of Restitution

International Scholastic Journal of Science, 2015
A basketball was released from varying drop heights to simulate the impact speeds of a typical soft, medium, and hard dribble. This was repeated across four different surfaces that students typically play on–exposed aggregate concrete, maple wood ...

Uniaxial compressive strength prediction and ratio parameter optimization of titanium tailings composite backfill materials using intelligent hybrid models

Deep Underground Science and Engineering, EarlyView.
Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling

Deflection characteristics of wood-joist floors

, 1960
Two separate criteria must be considered in designing joists, strength and deflection. Because specified deflection limits for wood-joist floors were found to vary from building code to building code and from country to country the author looked into how stiff residential wood- joist floors should be.

Associations Between Microbial Depletion and Autonomic Dysregulation in Binge‐Eating Disorder

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective The interplay between the gut microbiome and autonomic nervous system remains unexplored in binge‐eating disorder (BED). We aimed to explore specific microbial alterations in BED and examine their potential association with cardiac vagal tone as a distinct bio‐behavioral phenotype.
