ABSOLUTE INSTABILITY OF COMPRESSIBLE THREE-DIMENSIONAL FLOW

TASK Quarterly, 1999
In the present paper the instability character (absolute/convective) of compressible viscous flow around geometries rotating in uniform flow is analysed. The linear local stability theory is used to investigate the boundary layer stability.

THE BETWEEN-PLACE AND THE CULTURAL STUDIES

Travessias, 2007
In this paper, we investigate the importance of the term in-between, theoretically constituted in Silviano Santiagos work and thoroughly used in the discursive field of the Cultural Studies.

Study of wide band-gap crystal LiCaAlF6 by IR-reflection spectroscopy and ab initio calculations

EPJ Web of Conferences, 2017
Polarized IR-reflection spectra and results of ab initio calculations of vibrational and electronic properties of LiCaAlF6 single crystal are presented. It is shown that the crystal band gap is direct. Experimental and theoretical parameters are obtained

Pulp Screen Plugging Characteristics

BioResources
Aperture plugging is a phenomenon that limits both the capacity and efficiency of pulp screens, which are critical components of the papermaking process. An understanding of how plugs are created and how they can be avoided can enhance the manufacture of

Doppler and Non-Doppler Shifts in Dispersion Relations for Rossby Waves and Galilean Invariance

Russian Journal of Earth Sciences
The purpose of this work is to draw the reader's attention to a paradoxical fact – the existence of two different dispersion relations for linear Rossby waves: with Doppler and nonDoppler shifts.

Novel methotrexate long-acting system using ambroxol coating and hydroxypropyl methylcellulose encapsulation for preferential and enhanced lung cancer efficiency.

PLoS ONE
Methotrexate (MTX) is classified as an antimetabolite. It's commonly used to treat lung cancer. MTX is an immunosuppressant following the above-mentioned mechanism of action due to its poor selectivity.

Comparative Study of Matrix Methods for Modeling the Dispersive Character of Ultrasonic Guided Waves

Engineering Transactions
This paper presents a comparative study of various matrix methods for obtaining the dispersion curves of ultrasonic guided waves in anisotropic media for both planar and cylindrical geometries. First, the mathematical formulation of the problem is introduced.
