River Research and Applications, EarlyView.ABSTRACT Regulated rivers represent complex hydrological systems where groundwater–surface water interactions are governed by natural conditions and human interventions. This study investigates the spatiotemporal dynamics of groundwater–surface water exchanges in the Nechako River, British Columbia (Canada), using numerical simulations.

European Physical Journal C: Particles and FieldsIn this study, we investigate the gravitational collapses of rotating stellar systems accounting for gamma-ray burst jet progenitors. Based on the virial theorem of hadron collisional relaxations and Newtonian slow-rotating approximation, we analyze the ...

Particular aspects of calculating affecting factors of fireballs emerging from aircraft crash
MATEC Web of Conferences, 2018 The article reveals an algorithm of calculating the heat loads which emerge during fireball-involving accidents. By way of illustration it considers a situation when a heavy aircraft crashes in the vicinity of a typical reactor building of a nuclear ...

EVOLUTION OF COMET-LIKE ORBITS OF METEORITE- PRODUCING GROUPS AND THEIR PARENT BODIES
Odessa Astronomical Publications, 2019 This paper presents the results of the study of evolution of Jupiter-family comet-like orbits of six meteorite-producing groups, including sporadic fireballs from the IAU MDC database 2007 [1], sporadic meteors from the SonataCo database [2 ...

THE FORMATION AND DISSIPATION OF A METEOR COMA
Odessa Astronomical Publications, 2017 The results of reduction of instantaneous fireball photographs are presented. The observational data testify to the fact that linear dimensions of the region radiating after the meteor’s flight amount to tens and hundreds of meters, and in the case of ...

Standard GRB, Dirty Fireballs, and the Excluded Middle
, 2011 It is shown that the contribution of faint gamma-ray bursts (GRB) to the total allsky GRB energy flux is small. The allsky flux of GRB appears to be $5.3 \times 10^{-3}$ erg/$\rm cm^2 y$, with little additional component hidden within weak or otherwise ...

The Nexus Between Circular Economy and Sustainable Supply Chain Management: PRISMA Methodology
Sustainable Development, EarlyView.ABSTRACT The intersection of sustainable supply chain management (SSCM) and circular economy (CE) has attracted increasing academic and practical attention, emphasizing the need for integrated sustainability approaches. This study employs the PRISMA protocol and conceptualizes the CE–SSCM relationship as a dynamic system in which internal capabilities,
