Abstract: The effects of post-hydration heating over a broad range of temperatures are evident in many Mighei-like carbonaceous (CM) chondrites as a variety of mineral transitions. To better understand these processes and how a CM chondrite's starting composition may have affected them, we experimentally heated two meteorites with different degrees of aqueous alteration, Allan Hills 83100 and Murchison, at 25 °C temperature steps from 200 °C to 950 °C and 300 °C to 750 °C, respectively. During heating, synchrotron in situ X-ray diffraction patterns were collected.

Despite the remarkable achievements of female master athletes, their participation rates remain significantly lower than those of their male counterparts, particularly at more advanced ages. This review examines the biological sex gap in sports participation among master athletes and the subsequent disparity in empirical research, thereafter exploring possible contributing factors.

Purpose: This study both investigated and compared Gaelic games players' and practitioners' perceptions of the importance of postexercise recovery strategies.
Methods: Gaelic players (n = 1178 [n = 574 female], age 24.6 [6.
Objectives: The objective of this study was to synthesise the evidence of older persons' experiences of frailty.
Background: The world's population is ageing with those aged over 60 years expected to total 2 billion by 2050. Although not exclusive to ageing, there is a higher prevalence of frailty in older adults, with corresponding demand for related healthcare.
