Stability of Fireballs and γ-Ray Bursts
Fireballs are an essential part of any cosmological fl-ray burst. We drive here a stability criterion for fireballs and show that fireballs are Rayleigh-Taylor unstable in any region in which the entropy decreases outward.

ABSTRACT Resource efficiency has become a priority for the European agri‐food sector, yet adoption remains uneven across countries and firms. This study examines how European agri‐food small and medium‐sized enterprises (SMEs) adopt resource efficiency practices.

We describe fireballs that rehadronize from a perfect fluid of quark matter, characterized by the lattice QCD equation of state, to a chemically frozen, multi-component mixture, that contains various kinds of observable hadrons.

Evidence from spectra of bright fireballs [PDF]
Spectral data with dispersions from 11 to 94 A/mm on 4 fireballs of actual brightness of -4 to -12 magnitude and with velocities of about 30 km/s at 70 to 80 km heights are used for studies of meteor radiation problems.

ABSTRACT In the Chinese kimchi industry, manufacturers employ product names, photographs, and logistical strategies to promote their kimchi's “Koreanness.” So, what makes their kimchi “Korean,” and how does its Koreanness formulate kimchi's commodity value?

Real-Time Detection of Sporadic Meteors in the Intensified TV Imaging Systems
The automatic observation of the night sky through wide-angle video systems with the aim of detecting meteor and fireballs is currently among routine astronomical observations.

Abstract The focus on fostering innovative work behaviour among public servants in Vietnam reflects a strategic effort to enhance public service delivery and citizen satisfaction. However, empirical insights into how to effectively motivate such behaviours remain scarce.

The Independent Football Regulator: An Idea Whose Time Had Come?
Abstract Major public policy change is both driven and constrained by consensus and dissensus. As J. W. Kingdon observed, when old agreements falter, new alliances can be built, ‘sometimes very rapidly, by cutting in many and diverse interests’. We show how a peculiar set of circumstances following the Covid pandemic brought together an unusual ...

Research on Temperature Distribution Reconstruction of Deflagration Fields via Spectral-Image Fusion
Multispectral temperature measurement technology based on blackbody radiation theory has been widely applied in the field of non-contact temperature measurement. However, its applicability is limited by the single-point measurement mode.
