The asymptotic procedure proposed allows to derive closed hydrodynamical equations from the kinetic equations of carriers and phonons (treated as a partecipating species) in a photon background. The direct generation-recombination processes are accounted for. The fluid-dynamical equations constructed for the chemical potentials of carriers, temperature, and drift velocity, are related to the ex...

Proper chemical imaging tools are critical to the pharmaceutical industry due to growing regulatory demand for intermediate and end-product content uniformity testing. Herein we demonstrate stimulated Raman scattering (SRS) imaging of active pharmaceutical ingredient (API) and four excipients within tablets. Tablets from six manufactures were imaged with a speed of 53 s per frame of 512 × 512 p...

FDA's PAT Initiative provides an unprecedented opportunity for chemical engineers to play significant roles in the pharmaceutical industry. On-line process control, as an enabling process understanding tool and advanced quality control strategy, has been widely adopted in other industrial sectors. In the present manuscript, the authors will provide their perspectives on the need of chemical eng...

Using econometric evidence, this article confirms that distribution of medicines online is split into two market segments of very diverse quality, and identifies the factors that drive quality and quality assurance in this activity. Unlike fraudulent, 'rogue,' websites, which offer scant guarantees and usually sell just a few medicines without prescription, online pharmacies offering insurance ...

In recent years, there has been considerable interest in using microalgal lipids the food, chemical, pharmaceutical, and cosmetic industries. Several species can accumulate appreciable lipid quantities therefore are characterized as oleaginous. formulations, their derivatives one of main ingredients. Different classes great moisturizing, emollient, softening agents, work surfactants emulsifiers...

S. K. Shyama*, K. S. Rathore, Roshan Keshri B. N. Institute of Pharmaceutical Sciences, Udaipur Rajasthan 313001 Erythrocytes, also known as red blood cells, have been extensively studied for their potential carrier capabilities for the delivery of drugs and drug-loaded microspheres. Such drug-loaded erythrocytes are prepared simply by collecting blood samples from the organism of interest, sep...
