Modern Theology, EarlyView.Abstract Examining work by Rowan Williams, this essay explores what he often refers to as the ‘difficulty’ of writing theology. The difficulty of theology lies in engaging the ruse of having ultimate answers to ultimate questions. The stakes are high: ‘God‐talk’ must concern itself with truth, with reality.

Flow field and flame surface density of turbulent flames by simultaneous PIV/OH-PLIF measurements
Journal of Thermal Science and Technology, 2018 In this study, we have examined the flow field and the flame surface density in premixed combustion by simultaneous particle image velocimetry (PIV) and OH-planar laser induced fluorescence (OH-PIIF) measurements. Turbulent flames are formed in a cyclone-

Journal of Applied Toxicology, Volume 46, Issue 6, Page 1987-2002, June 2026.ABSTRACT Unsymmetrical dimethylhydrazine (UDMH), a highly toxic rocket propellant with known multiorgan effects, requires urgent characterization of its chronic low‐dose toxicity. Using an integrated approach including exploratory transcriptomics (n = 3/group) and metabolomic (n = 4/group) approaches in male Sprague–Dawley rats exposed to high‐dose ...

PFAS properties and destruction methods: A focus on enzymatic degradation
Journal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1126-1152, June 2026.Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...
