Mathematical-Physics Analyses of the Nozzle Shaping at the Aperture Gas Outlet into Free Space under ESEM Pressure Conditions

open access: yesSensors
The paper presents a methodology that combines experimental measurements and mathematical-physics analyses to investigate the flow behavior in a nozzle-equipped aperture associated with the solution of its impact on electron beam dispersion in an ...

Dispersion characteristics of a nonlinear elastic metamaterial

open access: yesAIP Advances, 2014
We study wave dispersion in a one-dimensional nonlinear elastic metamaterial consisting of a thin rod with periodically attached local resonators. Our model is based on an exact finite-strain dispersion relation for a homogeneous solid, utilized in ...

Algorithm of the Rehabilitation of Patients with Pigmentary Glaucoma

open access: yesActa Biomedica Scientifica, 2019
Background. Irreversible changes in corneoscleral trabecula lead to persistent hydrodynamic disturbances not only in pigmentary glaucoma but also in pigmentary dispersion syndrome. In these cases isolated laser iridectomy cannot compensate ophthalmotonus

Phenomenology of the temperature-frequency dispersion of electrical properties of aluminium-substituted lithium-iron spinel

open access: yesФізика і хімія твердого тіла, 2020
The conductivity of the Li-containing Al-oxoferrite samples has been studied. Using Jonsher’s phenomenological approach, existence of 2 types of conductivity (electronic and ionic) in the above mentioned samples has been confirmed. Using Cole-Cole method,

The dramatically dispersive character of the traveling wave

open access: yesAIP Conference Proceedings
Using optical coherence tomography (OCT) vibrometry we studied wave propagation by recording at multiple longitudinal positions in the gerbil and guinea pig cochlea. Our aims are to (1) fully portray the unusual dispersive character of the wave; (2) derive from these properties the underlying physics of the wave and the way it is regulated by ...

SURFACE CHARACTER OF IRON OXIDE/CARBON NANOPARTICLES SYNTHESIZED BY SUBMERGED ARC DISCHARGE METHOD IN ETHANOL/UREA MEDIUM

open access: yesAlchemy, 2017
Synthesis of iron oxide nanoparticles modified with carbon has been successfully performed by submerged arc-discharge method in ethanol/urea medium. Iron oxide used in the fabrication process was prepared by iron electrolysis in an electrolyte solution ...

Role of Silica on Clay-Catalyzed Ozonation for Total Mineralization of Bisphenol-A

open access: yesMolecules, 2023
Catalytic ozonation for the total mineralization of bisphenol-A (BPA) from aqueous solution was investigated in the presence of various silica-based catalysts such as mesoporous silica, acid-activated bentonite (HMt) and montmorillonite-rich materials ...

The interiorization of Brazilian violence, policing, and economic growth

open access: yesEconomiA, 2015
Brazilian homicide rates are among the highest in the world, inclusive of actual war zones. However, the character of Brazil's violence is changing.

The Evolution and Biogeography of Wolbachia in Ants (Hymenoptera: Formicidae)

open access: yesDiversity, 2020
Wolbachia bacteria are widely distributed across invertebrate taxa, including ants, but several aspects of this host-associated interaction are still poorly explored, especially with regard to the ancestral state association, origin, and dispersion ...
