Article Abstract

Carbon-fiber-reinforced plastics (CFRPs) are of increasing popularity in a wide range of applications, and microwave curing promises significant reduction in processing times. However, for the design of an efficient microwave curing system, the composites' effective material parameters must be known. This work presents a measurement system using a wall perturbation approach with a coaxial cavity to determine the effective conductivity of a CFRP along the fiber direction.

Habitat fragmentation represents a multifaceted global conservation threat, exerting both direct and indirect effects on individual animals and communities. Reptiles, particularly smaller species with limited migratory abilities, are especially vulnerable to these changes. This study examines how small reptiles adapt their life history strategies in fragmented habitats and determines whether their responses are primarily due to phenotypic plasticity or genetic adaptation.

Cigarette smoke (CS) has detrimental effects on placental growth and embryo development, but the underlying mechanisms remain unclear. This study aims to investigate the impact of CS on trophoblast cell proliferation and regulated cell death (RCD) by examining its interference with iron-sulfur cluster (ISC) proteins and the CIA pathway. Exposure to CS disrupted the cytosolic ISC assembly (CIA) pathway, downregulated ISC proteins, and decreased ISC maturation in the placenta of rats exposed to passive smoking.
