Gender and Segregation: An Introduction
Gender &History, Volume 37, Issue 3, Page 795-804, October 2025.ABSTRACT This introduction to the Special Issue explores the ways in which a gendered analysis illuminates histories of segregation. It argues three key points. First, it is essential to understand segregation from an intersectional perspective, one that fully integrates gender alongside other factors and dynamics in order to fully understand the ...

Observational clues for a role of circumstellar accretion in PMS X-ray activity [PDF]
, 2002 We revisit the published analyses of ROSAT X-ray observations of the star forming regions NGC 2264 and Chamaeleon I (~3 and ~5 Myr old respectively) in the light of newly published optical data.

Higher Objectives of Islamic Law (Maqāṣid al‐Sharīʿa) in Substantiating Justice in Land Tax
The Muslim World, Volume 115, Issue 4, Page 295-319, Autumn 2025.Abstract This article discusses the relationship between the systemization of kharāj (land tax) and the higher objective of Islamic law or Maqāṣid al‐Sharīʿa. After the conquest of Sawād region (located in modern‐day southern Iraq), the First Caliph ʿUmar (634 ‐ 644 CE) introduced a new approach to the distribution of ghanīmah (spoils of war), leaving ...

Permitted Iron Emission Lines in the Classical T Tauri Star DR Tauri
The Astrophysical Journal, 1998 We present a study of permitted emission lines of Fe I and Fe II in the spectrum of the high-accretion rate classical T Tauri star DR Tau. Echelle spectra collected at the 4 m Mayall telescope at Kitt Peak National Observatory between 1988 and 1992 include four epochs with red spectral coverage (~5000-6800 A) and three with blue spectral coverage ...

An ecological framework for microbial metabolites in the ocean ecosystem
Limnology and Oceanography Letters, Volume 10, Issue 5, Page 636-659, September 2025.Abstract The ocean microbe‐metabolite network involves thousands of individual metabolites that encompass a breadth of chemical diversity and biological functions. These microbial metabolites mediate biogeochemical cycles, facilitate ecological relationships, and impact ecosystem health. While analytical advancements have begun to illuminate such roles,

, 2016 Most existing studies of the angular momentum evolution of young stellar populations have focused on the youngest (1-3 Myr) T Tauri stars. In contrast, the angular momentum distributions of older T Tauri stars (4-10 Myr) have been less studied, even ...

Lithium abundances in classical and weak T Tauri stars
The Astrophysical Journal, 1992 A study on the lithium abundance in 36 T Tauri stars (mass range 0.4-2.25 M ⊙ ), partly based on high-dispersion spectra taken with the Isaac Newton Telescope, is presented. Veiling effects have been taken into account when measuring the Li I λ670.8 nm doublet equivalent width.
