The methods of differential geometry are used with the assumption that rays of light follow geodesic trajectories in a space whose metric is determined by the refraction index. Keeping this in mind, we show that these hypotheses are equivalent to…

The thesis examines the utility of a pre-developed conceptual framework for learning about the human resource development (HRD) needs in a national context. The literature review focuses on knowledge-building within the main development theories and paradigms, two mainstream approaches to…

To calculate retinal magnification and visual acuity in highly myopic phakic eyes corrected with anterior chamber intraocular lenses (IOLs) versus correction by other methods.
Relative retinal magnification (RRM) was used to study changes in retinal image size induced by different…

This study examined the prevalence of information epidemics in the physics literature. The primary interest was to find out whether outliers observed on time series charts of literatures are due to information epidemics, whether these epidemics are widespread occurrences in…

ABSTRACT: Fifty-three endophytic enterobacteria isolates from citrus, cocoa, eucalyptus, soybean, and sugar cane were evaluated for susceptibility to the antibiotics ampicillin and kanamycin, and cellulase production. Susceptibility was found on both tested antibiotics. However, in the case of ampicillin susceptibility…

When aberrations are small, it is possible to use wave aberration variance to obtain the position of the best image plane in both conventional and holographic optical systems. However, when aberrations increase, this measurement is not sufficient and it does…

A spectroelectrochemical study of the adsorption and oxidation of glycine on a Pt(111) electrode has been carried out in 0.1 M HClO4 solution. Two types of adsorbate were identified. On the one hand, strongly adsorbed cyanide which comes from the…

Previously we described a large collection of cloned human DNAs that encode chemically defined missense mutations
within the ribosomal protein S14 sequence. We determined that biologically inactive (i.e. null) alleles resulted primarily
from point mutations targeted to two internal segments…

Para facilitar la gestión de revistas, su publicación y difusión en línea la UNLP ha creado el proyecto denominado Portal de Revistas de la UNLP.
El portal sirve a revistas existentes que no cuentan con una versión digital, a…
