Period Changes of Mira Variables, RR Lyrae Stars, and Type II Cepheids

open access: yes, 2013
Mira variables, RR Lyrae variables, and type II Cepheids all represent evolved states of low-mass stars, and long term observations have revealed that changes in pulsation period occur for each of these classes of variable. Most Mira variables show small or no period changes, but a few show large period changes that can plausibly be associated with ...

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

open access: yesStructural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.

Microplastics and the Endocrine–Metabolic Interface: Novel Diagnostic Tools Targeting Thyroid–Adipose Axis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Microplastics (MPs) have been identified as major environmental contaminants that can affect organisms directly and act as carriers of particles and chemical additives, thereby aggravating endocrine networks that coordinate metabolic homeostasis.
