Rosenstone Goes to Quilombo/The Quilombo Goes to Rosenstone
Bulletin of Latin American Research, Volume 46, Issue 1, January 2027.ABSTRACT This article examines Cacá Diegues's Quilombo (1984) through Robert Rosenstone's concept of the innovative historical film, focusing on the film's reworking of Palmares through music, ritual, performance and allegory. While Rosenstone provides a productive framework for understanding its cinematic engagement with the past, the article argues ...

Chaotic motion in a comet disk beyond Neptune - The delivery of short-period comets
The Astronomical Journal, 1989 Recent Monte Carlo simulations have demonstrated that a source with a spherical distribution of orbital angular momenta such as the Oort Cloud cannot give rise to the highly flattened distribution of short-period comets. It was also demonstrated that the problem of delivery could be resolved if short-period comets originate in a low inclination disk of

, 2010 Aims. The aim of this paper is to contribute to the characterisation of the general properties, differences, and commonalities of the short period comet family and, more in particular, to characterise the dust environment of three poorly studied members ...

Glia, Volume 74, Issue 12, December 2026.Müller glia and the retinal pigment epithelium interact around cone outer segment in the subretinal space of both zebrafish and mouse. The contacts are established early during development but subsequent to outer segment emergence. ABSTRACT Homeostasis of the vertebrate retina critically depends on two non‐neuronal cell populations, Müller glia and the

Investigation of Split Comet 240P/NEAT
The Astronomical JournalWe present time-series observations of the split comet 240P/NEAT near perihelion, obtained using the Nordic Optical Telescope. The brighter component, 240P-A, has an estimated radius in the range 400–600 m, and loses dust at the peak rate 130 kg s ^−1 ...

European Journal of Haematology, Volume 117, Issue 6, Page 1637-1646, December 2026.ABSTRACT Background Higher von Willebrand factor (VWF) levels and lower ADAMTS13 activity are linked to increased risk of atherosclerotic cardiovascular disease, but their association with atherosclerosis burden, a potential underlying mechanism, remains unclear.

A Dormant Captured Oort Cloud Comet Awakens: (18916) 2000 OG44
The Astrophysical Journal LettersWe report the discovery of activity emanating from (18916) 2000 OG _44 (alternately designated 1977 SD), a minor planet previously reported to be both an extinct comet and an asteroid on a cometary orbit. We observed 2000 OG _44 with a thin tail oriented
