Estimados lectores de la revista ARS Pharmaceutica,
 Son ya más 60 años desde que Pharmaceutica comenzó sus primeras publicaciones, y entonces el incremento en calidad los artículos así como regularidad publicaciones se ha mantenido reto constante.

Standard theories of the influence of a fluctuating director on spin relaxation in nematic liquid crystals are based on the notion that the mean-square angular displacement (8’) of the director is small, such that terms of this and higher orders are negligible. One consequence of this ‘small-angle’ approximation is that director fluctuations contribute only to the spectral density J , ( o o ) a...

Interactive narrative environments offer significant potential for creating engaging narrative experiences that are tailored to individual users. Increasingly, applications in education, training, and entertainment are leveraging narrative to create rich interactive experiences in virtual storyworlds. A key challenge posed by these environments is devising accurate models of director agents’ st...

We have studied the linearity of XP3062 Philips photomultipliers over a range of more than four orders of magnitude. The effect of continuous light background on the gain was also investigated. We have concluded that the XP3062 is a good candidate for the Auger FD camera.
