The Anatomical Record, EarlyView.Abstract Dental microwear texture analysis (DMTA) has emerged as a valuable method for investigating the feeding ecology of vertebrates. Over the past decade, three‐dimensional topographic data from microscopic regions of tooth surfaces have been collected, and surface texture parameters have been published for both extant and fossil species.

Study of the effect of green sand properties on thermal conductivity variation of sand mould
Journal of Engineering and Applied ScienceThermal conductivity of moulding sands is very poorly known. In addition, the study of thermal conductivity variation of moulding sand as a function of its properties is a crucial step in the prediction of moulding defects.

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy
The Anatomical Record, EarlyView.Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Efficacy of Drying Maize Seeds Using Zeolite Beads Under Hermetic Storage Conditions
Cereal Chemistry, EarlyView.ABSTRACT Background Sun drying of seeds prior to storage is a common practice in Sub‐Saharan Africa (SSA), but this method is unpredictable, especially during rainy seasons. Seed longevity and survival in storage depend on seed moisture content (MC); hence, controlling MC in storage is essential.
