Revisiting the Total Hildebrand and Partial Hansen Solubility Parameters of Analgesic Drug Meloxicam

Liquids, 2023
The reported total Hildebrand solubility parameter (δ2) value of meloxicam, as calculated based on the group contribution method proposed by Fedors, was compared with those estimated based on the maximum solubility peaks observed in different aqueous ...

Different Patterns of Chromospheric Evaporation in a Flaring Region Observed with Hinode/EIS

, 2010
We investigate the chromospheric evaporation in the flare of 2007 January 16 using line profiles observed by the EUV Imaging Spectrometer (EIS) onboard Hinode. Three points at flare ribbons of different magnetic polarities are analyzed in detail. We find

A 19F Solvatomagnetic Comparison Method for the Determination of the α1 Scale of Solvent Hydrogen‐Bond Donation and Its Application to Deep Eutectic Solvents

Journal of Physical Organic Chemistry, Volume 38, Issue 1, January 2025.
A single 19F NMR spectrum of a solution of 4‐fluoro‐2‐methylpyridine and of 4‐fluoronitrobenzene yields the hydrogen‐bond donation parameter α1 of the solvent, through the solvatomagnetic comparison method. ABSTRACT We develop a nonsolvatochromic comparison method for the determination of the α1 scale of solvent hydrogen‐bond acidity by means of 19F ...

Carbonyl stretching vibrations of 5-halogen-2-thiophenecarboxaldehydes: KBM, AN, SWAIN and LSER parameters

Pamukkale University Journal of Engineering Sciences, 2016
Halogen and solvent influence on the conformational stability and carbonyl stretching vibration of 5-Halogeno-2-thiophene-carboxaldehydes (C5H3XOS; X=F, Cl or Br) were investigated by the density functional theory using the B3LYP functional, 6-311+G(3df,p) basis set and polarizable continuum model. Calculations were performed by the cis and trans forms

Modeling headspace solid-phase microextraction of volatile organic compounds from water samples with porous coatings using finite element analysis

Advances in Sample Preparation, 2022
This research was aimed at the development of the COMSOL Multiphysics® (CMP) model for simulating the headspace (HS) solid-phase microextraction (SPME) of volatile organic compounds (VOCs) from water using Carboxen/polydimethylsiloxane coating at 25 °C ...

Solar stereoscopy - where are we and what developments do we require to progress? [PDF]

, 2009
Observations from the two STEREO-spacecraft give us for the first time the possibility to use stereoscopic methods to reconstruct the 3D solar corona. Classical stereoscopy works best for solid objects with clear edges.

RETRACTED: Tolerable random interruption duration based reliability estimation of stand alone hybrid renewable energy system by network reduction and sequential Monte Carlo simulation

IET Generation, Transmission &Distribution, Volume 18, Issue 24, Page 4168-4179, December 2024.
This paper evaluates reliability indices for a stand‐alone hybrid renewable energy system under the consideration of tolerable random interruption duration in the event of down time. Abstract This paper presents a novel tolerable random interruption duration (TRID) concept for estimation of reliability indices of stand‐alone hybrid renewable energy ...

A detailed mathematical model of the human atrial cardiomyocyte: integration of electrophysiology and cardiomechanics

The Journal of Physiology, Volume 602, Issue 18, Page 4543-4583, 15 September 2024.
Abstract figure legend Three phases of novel human atrial electromechanically coupled model, MBS2023. Phase 1 deals with model development, the conceptual background, and the coupling of forward and backward pathways. Phase 2 is based on calibration of parameters related to contraction, stretch activated channels, and Ca2+ handling.

A Nonlinear Force-Free Magnetic Field Approximation Suitable for Fast Forward-Fitting to Coronal Loops. II. Numeric Code and Tests

, 2012
Based on a second-order approximation of nonlinear force-free magnetic field solutions in terms of uniformly twisted field lines derived in Paper I, we develop here a numeric code that is capable to forward-fit such analytical solutions to arbitrary ...
