Abstract This study aimed to identify species of Astyanax bimaculatus group from four Itaipu Reservoir tributaries (Paraná River Basin) by cytogenetics and molecular markers (COI) to investigate the possible occurrence of cryptic diversity in part o

ABSTRACT The transposable elements (TE) have been widely applied as physical chromosome markers. However, in Loricariidae there are few physical mapping analyses of these elements. Considering the importance of transposable elements for chromosomal e

Basic and molecular cytogenetic techniques were carried out in 3 Neotropical region populations of catfishes, two of Trachelyopterus galeatus (one from the marshlands of Paraguay River basin and another from Lago Catalão, Amazon River basin) and one

I describe a simple new method for collimating a Cassegrain telescope that gives near-perfect correction over a wide field of view. This method was used to collimate the 6.5 m MMT in 2002 with remarkably good results. The first step is to point the p

We describe a multi-element refractive corrector for the prime focus of the proposed Lowell four-meter telescope. The design provides sub-half arcsecond images over a two-degree field of view, with a flat image surface and images that are confocal ac

The Gemini Laser Launch Telescope will reside behind the secondary support structure of the Gemini 8m telescope, where it will expand an incoming sodium laser beam to 450 mm diameter and launch it into the sky, co-axial to the main telescope. The tig

Seeing is generally caused by non-homogeneous variations in the refractive index of the column of air in the observed light path. The refractive index is affected by wavelength, air pressure, temperature and relative humidity. In this paper the Cauch

The WIYN 3.5 meter telescope uses active thermal control of the primary mirror and both active and passive ventilation of the observatory enclosure. These features have proven effective for delivering consistently excellent images, and make the WIYN
