Images for an Isothermal Ellipsoidal Gravitational Lens from a Single Real Algebraic Equation [PDF]

open access: yes, 2002
We present explicit expressions for the lens equation for a cored isothermal ellipsoidal gravitational lens as a single real sixth-order algebraic equation in two approaches; 2-dimensional Cartesian coordinates and 3-dimensional polar ones.

Nucleic Acid-Based Diagnostic Tests for the Detection SARS-CoV-2: An Update

open access: yesDiagnostics, 2021
The coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began as a cluster of pneumonia cases in Wuhan, China before spreading to over 200 countries and territories on six continents in less than six

Adaiabtic theorems and reversible isothermal processes

open access: yes, 2005
Isothermal processes of a finitely extended, driven quantum system in contact with an infinite heat bath are studied from the point of view of quantum statistical mechanics.

First Order Chemical Reaction Effects on Exponentially Accelerated Vertical Plate with Variable Mass Diffusion in the Presence of Thermal Radiation

open access: yesInternational Journal of Applied Mechanics and Engineering, 2015
Effects of transfer of mass and free convection on the flow field of an incompressible viscous fluid past an exponentially accelerated vertical plate with variable surface temperature and mass diffusion are studied.

Bi-quartic parametric polynomial minimal surfaces

open access: yes, 2015
Minimal surfaces with isothermal parameters admitting B\'{e}zier representation were studied by Cosin and Monterde. They showed that, up to an affine transformation, the Enneper surface is the only bi-cubic isothermal minimal surface.

The density structure and star formation rate of non-isothermal polytropic turbulence [PDF]

open access: yes, 2015
The interstellar medium of galaxies is governed by supersonic turbulence, which likely controls the star formation rate (SFR) and the initial mass function (IMF).

Hydromagnetic Flow Past an Exponentially Accelerated Isothermal Vertical Plate with Uniform Mass Diffusion in the Presence of Chemical Reaction of first Order

open access: yesInternational Journal of Applied Mechanics and Engineering, 2013
An exact solution of an unsteady flow past an exponentially accelerated infinite isothermal vertical plate with uniform mass diffusion in the presence of a transverse magnetic field has been studied.

Deactivation of TEM-1 beta-Lactamase investigated by isothermal batch and non-isothermal continuous enzyme membrane reactor methods [PDF]

open access: yes, 2009
The thermal deactivation of TEM-1 β-lactamase was examined using two experimental techniques: a series of isothermal batch assays and a single, continuous, non-isothermal assay in an enzyme membrane reactor (EMR).

The Commercial Validation of Three Tomato Brown Rugose Fruit Virus Assays

open access: yesPhytoFrontiers, 2023
Tomato brown rugose fruit virus (ToBRFV) was first described infecting tomatoes in 2015 after breaking tobamovirus resistance in production cultivars. As an emerging pathogen, ToBRFV commercial assays were developed and subsequently validated.
