ABSTRACT We investigate the temporal and colour variability of 897 blazars, comprising 455 BL Lacertae objects (BL Lacs) 442 Flat Spectrum Radio Quasars (FSRQs), selected from Roma-BZCAT catalogue, using multiband light curves Zwicky Transient Facility (ZTF DR6) survey. Assessing characteristics over ∼2 yr time-scales, we found that 18.5 per cent (84 out 455) Lacs showed a stronger bluer-when-b...

Introduction: AKI incidence reported in COVID-19 patients is increasing with contradictory study results about development increased mortality. This was conducted to assess a possible correlation between risk factors that led and Methods: A total of eight articles found through an online database published 2020 2021 were used. 9 455 divided into non-AKI.

Continued gravitational collapse gives rise to curvature singularities. If a curvature singularity is globally naked then the space-time may be causally future ill-behaved admitting closed time-like or null curves which extend to asymptotic distances and generate a Cosmic Time Machine (de Felice (1995) Lecture Notes in Physics 455, 99). The conjecture that Cosmic Time Machines give rise to high...
