Application of Cantabrian and Binder Drainage Tests in Designing of Porous Asphalt Binder Content [PDF]

open access: yes, 2004
Traditional mix design methods which normally incorporate the Marshall test are not appropriate to design porous asphalt because of the insensitivity of the Marshall stability values to variations in binder content.

Nanoclay‐Engineered Scaffolds for the Controlled Delivery of Biomolecules in Regenerative Medicine

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Regenerative medicine combines biomaterials, cells, scaffolds, and bioactive agents via modern technologies to aid in the reconstruction and repair of damaged tissues. Among these, nanoclay scaffolds have demonstrated unique advantages in facilitating the delivery of therapeutic agents.

From armadillos to sloths: Patterns and variations in xenarthran coronary anatomy

open access: yesThe Anatomical Record, EarlyView.
Abstract Species of the superorder Xenarthra play a vital ecological role in the Neotropics. Despite their evolutionary significance, anatomical studies on their coronary circulation remain scarce. This study investigated the coronary anatomy of 82 hearts from nine Xenarthra species across the Dasypodidae, Myrmecophagidae, and Bradypodidae.

Marshall Properties and Rutting Resistance for Asphaltic Mixtures Modified by Nano-Montmorillonite

open access: yesJournal of Engineering
Rutting is a significant problem in flexible asphalt pavements, causing permanent deformation. Increased traffic, axle load, tire pressure, and hot weather have recently accelerated rutting in flexible pavements. Several researchers have suggested using

Effects of intermittent exposure to hypobaria and cold on the microarchitecture and morphofunctional profile of rat gastrocnemius muscle

open access: yesThe Anatomical Record, EarlyView.
Abstract Intermittent hypobaric hypoxia (IHH) enhances oxygen transport, muscle metabolism, and cardiovascular health; however, the combined effects of hypobaria and cold are less well understood. Exposure to these stressful environmental factors, even intermittently, can affect skeletal muscle due to its plasticity, thereby altering its metabolic and ...
