Pasto, Colombia

The University of Nariño , also called Udenar, is a public, coeducational, research university based primarily in the city of Pasto, Nariño, Colombia. It is the largest higher education institution by student population in the department with 9,867 students. Its origins can be traced to 1712, but it was officially established by governor Julian Buchelli through decree 049 of November 7, 1904.The university has three campuses in Pasto. The main one, known as the University City of Torobajo, is located in the northern part of the city in the neighborhood of the same name, the second in the neighborhood of San Vicente is known as the Panamericana campus, and the last is in the city's downtown, which was its first location. Udenar has several satellite campuses across the department in the cities of Ipiales, Samaniego, Tumaco, and Tuquerres. The university offers education at technological, undergraduate and postgraduate levels, with 56 academic programs, which includes 5 master's and a doctorate in education. It is also the host for 79 research groups recognized by COLCIENCIAS.The university is member of the Association of Colombian Universities and the Iberoamerican University Network Universia.

Here we show that the Weak Basis Transformation is an appropriate mathematical tool that can be used to find texture zeros in the quark mass matrix sector of the Standard Model. So, starting with the most general quark mass matrices and taking physical data into consideration, it is possible to obtain more than three texture zeros by any Weak Basis transformation. The general quark mass matrices considered, were obtained through a special weak basis transformation wherein the up-quark mass matrix (down-quark mass matrix ) has been taken to be diagonal and the down-quark mass matrix (up-quark mass matrix), in general form, includes the Cabibbo-Kobayashi-Maskawa matrix. © 2015 Elsevier B.V..

Stimulated by the recent attention given to the texture zeros found in the quark mass matrices sector of the standard model, an analytical method for identifying (or excluding) texture zeros models will be implemented here. Starting from arbitrary quark mass matrices and making a suitable weak basis transformation, we are be able to find an equivalent quark mass matrix. It is shown that the number of nonequivalent quark mass matrix representations is finite. We give exact numerical results for parallel and nonparallel four-texture zeros models. We find that some five-texture zeros Ansätze are in agreement with all present experimental data, and we confirm definitively that six-texture zeros of Hermitian quark mass matrices are not viable models anymore. © 2012 American Physical Society.

Immature stages of five species of Gerridae are described and illustrated for the first time: Rheumatobates longisetosus Polhemus & Manzano, Rheumatobates probolicornis Polhemus & Manzano, Rheumatobates peculiaris Polhemus & Spangler, Telmatometra whitei Bergroth and Telmatometroides rozeboomi (Drake & Harris). The first two were distributed in the Pacific region of Colombia, R. peculiaris distributed along the Pacific region of Colombia to Ecuador, T. whitei distributed from Mexico to Colombia and Ecuador, T. rozeboomi from Central America to Colombia and Ecuador. The five species were collected in the southwest of Colombia, near the Pacific coast. Copyright © icipe 2013. Source
