Moments of the Negative. Two Small Nihilist Episodes from the 1940s [PDF]

open access: yesPhainomena
Evoking Leo Strauss’s 1941 text “German Nihilism” and his forceful claim that nihilism is above all “the rejection of the principles of civilization as such,” my intention is to thematize the possible forms of coexistence that survive and develop despite

Evaluation of the impact strength of the traction gearbox housing for the traction of a high-speed electric train in terms of deformation rate of the material

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2023
Introduction. Solving a wide range of problems to maintain the strength of train undercarriage under the impact of ballast particles, such as ice chunks, during the cold season is considered a topical issue for high-speed railways.

Creative Destruction and Cultural Lag in the Digital Age [PDF]

open access: yes, 2020
Recently, there has been renewed interest in the two ideas of \u201ccreative destruction\u201d and \u201ccultural lag\u201d both brought together in this article to analyze cutting-edge changes in the digital world, especially as they relate to ...

Quantum scaling laws in the onset of dynamical delocalization [PDF]

open access: yes, 2006
We study the destruction of dynamical localization, experimentally observed in an atomic realization of the kicked rotor, by a deterministic Hamiltonian perturbation, with a temporal periodicity incommensurate with the principal driving. We show that the

Reviewing South Africa’s Non-Proliferation Policy and Strategic Trade Controls

open access: yesThe Thinker
The prohibition of Weapons of Mass Destruction (WMDs) in South Africa is governed through the implementation of an integrated and robust non-proliferation and arms control policy, legislative and regulatory framework, which has been revised and improved

Modeling of Chelyabinsk meteorite fall [PDF]

open access: yesКомпьютерные исследования и моделирование, 2013
We study the motion and destruction of Chelyabinsk meteoroid using simple physical and mathematical models. We evaluate the parameters of the motion, taking into account the ablation and mechanical destruction of the meteoroid, and compare our results to

Destabilization of the hard coal microstructure by a weak electric field [PDF]

open access: yes, 2018
This study aims to analyse physical and chemical changes in hard coal samples under the influence of low-intensity electric fields in comparison to the fragments of ejected coal, as well as the coal samples selected from the zones ...
