The skeleton of the green Iguana iguana (Squamata: Iguanidae) and its intraspecific morphological variation

The Anatomical Record, EarlyView.
Abstract The green iguana (Iguana iguana) is an iguanine lizard with herbivorous and arboreal habits, whose distribution spans through South America, Central America to the south of North America. Although the genus Iguana is well‐known, the species still lacks a comprehensive and up‐to‐date anatomical study, particularly addressing the axial skeleton,

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Comparative Study of High Voltage Spinel∥Lithium Titanate Lithium‐ion Batteries in Ethylene Carbonate Free Electrolytes

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
FEC and sulfone‐based co‐solvents are investigated as EC‐free electrolytes for LNMO∥LTO cells. FEC‐containing electrolytes demonstrate enhanced electrochemical stability by stabilizing the CEI and SEI layers, mitigating transition metal migration. Conversely, sulfone electrolytes form thinner CEIs and thick, sulfur‐rich SEIs, which are less effective ...

Preliminary Numerical Evaluation of Directly Heated Structured Packings to be Used for Separation Processes

Chemie Ingenieur Technik, EarlyView.
In terms of electrification, directly heated structured packings are a viable option. They offer the advantage of providing energy where it is required, thereby positively impacting the separation process and helping to minimize heat loss. Using CO2 desorption from aqueous MEA solution as an exemplary process, different heating strategies are compared.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

Deep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...
