| Fractality has emerged as a feature of the organization of some complex natural systems. Several biological secretions show fractal-like patterns for their crystallization phenomena but their presence in crystallizations of bovine cervical mucus (BCM) is yet unknown. In order to assess the fractality of BCM crystallization, samples of this fluid were taken from heifers at oestrus, their crystalline patterns photographed and its morphology analyzed. Among the many images obtained for BCM crystallizations, one of them had a highly symmetrical geometric arrangement, possessing three zones characterized by pine-like, arboriform structures, evidencing a remarkable similarity between them. Moreover, fractal dimensions obtained for these zones were statistically... |

| Las transformaciones de la Región Metropolitana de Buenos Aires han impactado en territorios rurales. Es el caso de Cañuelas, donde “proyectos de desarrollo urbano” han avanzado, con lo cual desplazaron actividades agrícolas. No obstante, algunos de ellos intentan ser parte de la “nueva ruralidad” que se busca para el partido. Esta investigación exploratoria busca contribuir al estado del arte sobre “nueva ruralidad”. Específicamente, indagamos sobre transformaciones territoriales y modelos de desarrollo que se disputan hegemonía en el territorio. Se utiliza un enfoque que conjuga estudios urbanos y rurales, una metodología cualitativa y basada en fuentes secundarias. Los resultados plantean una... |
