Development and validation of a UPLC-MS method for determination of atazanavir sulfate by the “analytical quality by design” approach [PDF]

open access: yes, 2020
A UPLC-MS method for the estimation of atazanavir sulfate was developed using the “analytical quality by design” approach. The critical chromatographic quality attributes identified were retention time, theoretical plates and peak tailing.

New insights on the matter-gravity coupling paradigm

open access: yes, 2012
The coupling between matter and gravity in General Relativity is given by a proportionality relation between the stress tensor and the geometry. This is an oriented assumption driven by the fact that both the stress tensor and the Einstein tensor are ...

Surface singularities in Eddington-inspired Born-Infeld gravity

open access: yes, 2012
Eddington-inspired Born-Infeld gravity was recently proposed as an alternative to general relativity that offers a resolution of spacetime singularities. The theory differs from Einstein's gravity only inside matter due to nondynamical degrees of freedom,

Software-assisted analytical Quality by Design for stability-indicating method development: integration of DoE and predictive retention modeling using MODDE® and DryLab® [PDF]

open access: yesMakedonsko Farmacevtski Bilten
In modern pharmaceutical development, the increasing complexity of drug substances, formulations, and regulatory expectations has rendered traditional one-factor-at-a-time (OFAT) approaches to analytical method development inefficient and increasingly ...

Multivariate optimization and evaluation of quaternary mixture in bulk and co-formulated dosage forms by central composite design

open access: yesFuture Journal of Pharmaceutical Sciences, 2021
Background The current study describes the use of central composite design for multivariate optimization of resolution and retention time, taking into account different critical method parameters like organic phase, pH, flow rate, and wavelength for risk

Flavor Symmetries and The Problem of Squark Degeneracy

open access: yes, 1993
If supersymmetry exists at low energies, it is necessary to understand why the squark spectrum exhibits sufficient degeneracy to suppress flavor changing neutral currents.

Quality-by-design in pharmaceutical development: From current perspectives to practical applications [PDF]

open access: yes, 2021
Current pharmaceutical research directions tend to follow a systematic approach in the field of applied research and development. The concept of quality-by-design (QbD) has been the focus of the current progress of pharmaceutical sciences. It is based on,

Hidden Q-structure and Lie 3-algebra for non-abelian superconformal models in six dimensions

open access: yes, 2014
We disclose the mathematical structure underlying the gauge field sector of the recently constructed non-abelian superconformal models in six spacetime dimensions. This is a coupled system of 1-form, 2-form, and 3-form gauge fields.
