Report

The variable stars population of the extended young globular cluster NGC 1851

Autor: Ferro, A. Arellano, Parra, C. E. Pérez, Yepez, M. A., Fierro, I. H. Bustos, Prudil, Z., Guillen, L. J. Zerpa

We report VI CCD photometry of the globular cluster cluster NGC 1851. We aim to study the membership of the variable stars detected in the field of the cluster as listed in the Catalogue of Variable stars in Globular Clusters (CVSGC; Clement et al. 2

Report

The variable stars in the field of the bulge cluster NGC 6558

Autor: Ferro, A. Arellano, Guillen, L. J. Zerpa, Yepez, M. A., Fierro, I. H. Bustos, Prudil, Z., Parra, C. E. Pérez

We made a survey of the variable stars in a $13.2 \times 13.2$ arcmin$^2$ centered on the field of the Galactic bulge cluster NGC 6558. A total of 78 variables was found in the field of the cluster. Many of these variables are included in the Catalog

Desde la hermenéutica filosófica de Martin Heidegger al ser docente militar

Autor: Janett J. Zerpa Higuera

Publikováno v: Horizontes. Revista de Investigación en Ciencias de la Educación. 1:23-27

El estudio se enfoca en el ser docente militar a partir de la pregunta del ser de Martin Heidegger. Se hace necesario preguntarse por el “Es”: quién es ese sujeto y objeto del conocimiento y cómo se devela ante sí y ante los otros. Heidegger,

Publikováno v: Biomass and Bioenergy. 149:106075

There is a need for data on commercial-scale harvesting operations in hybrid poplar short rotation crops to better understand costs and logistics, especially for modeling large scale biorefineries. An investigation was conducted on the in-field perfo

Stem photosynthesis and hydraulics are coordinated in desert plant species

Autor: Louis S. Santiago, Antonio J. Zerpa, Eleinis Ávila-Lovera

Publikováno v: New Phytologist. 216:1119-1129

Coordination between stem photosynthesis and hydraulics in green-stemmed desert plants is important for understanding the physiology of stem photosynthesis and possible drought responses. Plants with photosynthetic stems have extra carbon gain that c
