Revisiting the nonsingular black holes in the 4-dimensional regularized Lovelock gravityThe European Physical Journal Plus - Tập 137 - Trang 1-11 - 2022
S. Habib Mazharimousavi
Static, spherically symmetric nonsingular/regular black holes in the vacuum
4-dimensional Lovelock gravity are revisited. We follow the footsteps of
Changjun Gao et al in their recent work (Gao et al. in Phys Dark Univ 31:100754,
2021) where they introduced nonsingular black holes in regularized Lovelock
gravity and studied their physical properties. In addition to what already has
been done, we i... hiện toàn bộ
Travelling waves and instability in a Fisher–KPP problem with a nonlinear advection and a high-order diffusionThe European Physical Journal Plus - Tập 136 - Trang 1-18 - 2021
José Luis Díaz Palencia
The instability of travelling waves (TW) in high-order operators has been a
source of investigation in the last years. Instability shall be understood as
the existence of oscillatory exponential bundles of solutions. One of the
principal topics to explore is related with the characterization of the
mentioned instability phenomena in the proximity of the stationary solutions
given by KPP-Fisher ter... hiện toàn bộ
Effect of impact force for dual-hose dry blasting nozzle geometry for various pressure and distance: an experimental workThe European Physical Journal Plus - Tập 135 - Trang 1-11 - 2020

Dry ice blasting plays an essential role in today’s cleaning industry, where
many industry players have used it after realizing its advantages. The
disadvantage of dry ice blasting is relatively small kinetic energy and offer
less aggressive clean effect, especially for dual-hose nozzle geometry. This
project was mainly to study the impact force of nozzle geometry of dry ice
blasting concerning pr... hiện toàn bộ
Simple synthesis, structural and optical properties of cobalt ferrite nanoparticlesThe European Physical Journal Plus - Tập 134 - Trang 1-10 - 2019
A. V. Ravindra, M. Chandrika, Ch. Rajesh, Pratap Kollu, Shaohua Ju, S. D. Ramarao
Cobalt ferrite (CoFe2O4) nanoparticles have been successfully synthesised by
simple and economic co-precipitation method at 90 °C for 2h using a
biodegradable surfactant (starch), and by annealing at 500 °C for 1, 2, and 6h.
The XRD patterns reveal spinel CoFe2O4 phase for as-synthesized and annealed
samples without any impurity phase. FTIR spectra also demonstrate the
characteristic absorption ba... hiện toàn bộ
Parametrization of cross sections for elementary hadronic collisions involving strange particlesThe European Physical Journal Plus - Tập 133 - Trang 1-34 - 2018

The production of strange particles (kaons, hyperons) and hypernuclei in light
charged-particle-induced reactions in the energy range of a few GeV (2-15 GeV)
has become a topic of active research in several facilities (e.g., HypHI and
PANDA at GSI and/or FAIR (Germany), JLab (USA), and JPARC (Japan)). This energy
range represents the low-energy limit of the string models (degree of freedom:
