Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

open access: yesEnergy Science &Engineering, EarlyView.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

open access: yesFire and Materials, EarlyView.
ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

The beetles of St. Lucia, Lesser Antilles (Insecta: Coleoptera): diversity and distributions [PDF]

open access: yes, 2009
The published beetle fauna of the island of St. Lucia is summarized. It contains 135 genera, and 175 species in 25 families. Four species are accidentally introduced by human activities. Twenty three species are endemic (restricted) to the island. Twenty

Wonder as a Gateway to Science Meaning‐Making: Primary Pupils’ Narrative Journeys

open access: yesFuture in Educational Research, EarlyView.
ABSTRACT This study explores how wonder fosters transformative learning in science education for pupils (11–12 years old), creating meaning about cycles in nature. As an emotional and epistemic trigger, wonder may bridge everyday experiences with abstract scientific concepts by stimulating curiosity and creativity. Through a narrative writing task, the

Anemomenotatic orientation in beetles and scorpions [PDF]

open access: yes, 1972
Orientation, by beetles and scorpions, according to wind direction and force are analyzed. Major efforts were made to determine: (1) which physical qualities of the air current influence anemomenotaxis, (2) which physiological mechanism is responsible ...

Enhancing the Sensitivity of Colorimetric Aptasensor Through Cd2+‐Thymine Interactions in ssDNA Loops for Food Contaminant Detection

open access: yesFood Safety and Health, EarlyView.
This picture illustrates a novel aptamer‐based colorimetric assay, which demonstrates that high sensitivity, selectivity, and reliability for the rapid detection of cadmium ions (Cd2+) in water. Molecular dynamics (MD) simulations have revealed that the complexes are more stable, with Cd2+ binding more tightly to the thymine (T) within the aptamer loop.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...
