The Evolution of Disk Winds from a Combined Study of Optical and Infrared Forbidden Lines

2020

We analyze high-resolution (dv=<10km/s) optical and infrared spectra covering the [OI] 6300 angstrom and [NeII] 12.81 micron lines from a sample of 31 disks in different evolutionary stages. Following work at optical wavelengths, we use Gaussian profiles to fit the [NeII] lines and classify them into HVC (LVC) if the line centroid is more (less) blueshifted than 30 km/s with respect to the stellar radial velocity. Unlike for the [OI] where a HVC is often accompanied by a LVC, all 17 sources with a [NeII] detection have either a HVC or a LVC. [NeII] HVCs are preferentially detected toward high accretors (Macc > 10$^{-8}$ Msun/yr) while LVCs are found in sources with low Macc, low [OI] …

Efeitos da sustentabilidade e valor logístico nas relações entre empresas de transporte marítimo

2020

Resumen El objetivo de este trabajo fue analizar cómo la sostenibilidad (económica, social y ambiental), bajo el enfoque de triple línea base, afecta la calidad de servicio, el valor logístico y la satisfacción en empresas del sector marítimo. Se propone un modelo teórico que se contrasta con la información suministrada por una muestra de 50 responsables de empresas (transitarios, importadores y exportadores) en Panamá. La información se analiza mediante la estimación de regresión por mínimos cuadrados parciales, que permite confirmar el carácter multidimensional de la sostenibilidad y del valor logístico. Los resultados también confirman que las percepciones de los clientes sobre las inici…
