The Universidad Bolivariana de Venezuela is a state university in Venezuela founded in 2003 by decree of President Hugo Chávez.The UBV is a part of the Chávez government's "Mission Sucre" social programs, which aim to provide free higher education to the poor. Consequently, enrollment at the UBV is free and open to all, regardless of academic qualifications, prior education or even nationality. The government expects the student body to grow to 1 million by 2009, with more than 190 satellite classrooms throughout Venezuela. The education programme at the UBV is generally in line with Hugo Chávez's democratic socialist vision of a Latin American "Bolivarian Revolution". Opposition leader Julio Borges though, labels it a "thinly disguised propaganda factory that takes advantage of the country's most vulnerable citizens". However, others are more optimistic. Maria Ejilda Castellano, the rector of the Bolivarian University in Caracas, has said that the institution is designed to benefit the poor precisely by encouraging the open exchange of ideas. Castellano said that the Bolivarian University is based on UNESCO principles for education and that "The professional produced by this institution will work for the transformation of society. She will be a critical thinker who can stimulate others and generate questions." Wikipedia.

This article presents the design of a Reed Solomon encoder circuit based on a concurrent LFCS - Linear Structure Concurrent Feedback - allowing the generation of code redundancy symbols in parallel, provided that you supply the k information symbols to encode simultaneously, the encoder provides at its output corresponding redundancy symbols. To achieve this development was generalized mathematical model describing the behavior of the encoder, the configuration was done in VHDL hardware description language of a Reed Solomon encoder, taking as case study the RS (7.3), the design was simulated validating the proposed operation, and finally the comparison of the encoder implementation between the sequential version and the version based on LFCS, obtaining a reduction of hardware components and optimizing the speed of response and power consumption. In conclusion, the proposed encoder design validates the concurrent model generalized from the correspondence with the architecture of LFCS.

The preferential solvation of thiophene- and furan-2-carboxaldehyde phenylhydrazone derivatives in DMSO-water and DMSO-n-octanol mixtures has been studied using visible absorption spectroscopy with a previous characterization of the electronic transitions by Time-Dependent Density Functional Theory (TDDFT) and solvatochromic study in several solvents with different hydrogen-bond donor capacity. The results indicate that the phenylhydrazones are preferentially solvated by clusters of DMSO-water existing in the solvent mixture and the dielectric enrichment as preferential solvation mechanism was discarded. A relation between local DMSO concentration with nitro groups and the electronegativity of the heteroatom of the five-membered ring was found. For DMSO-1-octanol mixtures, the results showed no preferential solvation. © 2012 Elsevier B.V. All rights reserved.

The bees are important animals in the pollination of them natural and cultivated plants, inclusive they have established specific relations, appearing botanical important species in the sustentation of bees's populations. The intention of this investigation was to identify the bees (Hymenoptera: Apoidea) visitors of W. americana L. (Sterculaceae) in agricultural area of the Rómulo Gallegos University, Guárico, Venezuela; in order to evaluate the potential of this plant in the managing of the bees. An area was established by 10 plants of W. Americana and all the visitors bees of this plant were collected with insect-net. The samplings were done between the hours 6:00-14:00, during October-November months (2008) by eight samplings for month. There were collected 3009 individuals distributed in four families and 40 species of bees, correspondents to: Apidae 2785 individuals, 22 species; Halictidae 186 individuals, 11 species; Megachilidae 35 individuals, five (5) species and Andrenidae three (3) individuals and two (2) species. Apis mellifera turned out to be the most frequent specie (52,21%). Ten species of bees (25% of the richness) 2835 individuals add up. W. americana is a specie of great potential for the maintenance of the richness and abundance of bees in the agricultural areas of the Rómulo Gallegos University.

This paper presents the experience in implementing the curriculum of the Training Program in Computer Science Degree for the Social Management of the Bolivarian University of Venezuela which is based on project-based learning as a means of integration of training university in accordance with the needs of the country. The axis modular curriculum is integrated into the basic unit, called the project, which develops permanently and continuously throughout the race, interacting with communities and institutions. The project includes training components of the axes that make up the curriculum to solve real problems, but of different complexity, throughout the race. © 2012 IEEE.

Achieving success in modern industry requires the orchestration of the stakeholders of the manufacturing process as well as accessing information distributed along the manufacturing network involved; this latter is a key factor. Many manufacturing approaches have appeared with the aim of speeding up the manufacturing process by means of accessing certain knowledge encoded in a way that makes it reusable. Ontologies and the Semantic Web are emerging technologies proposed for knowledge representation and reasoning, which tend to be adopted in the manufacturing domain in order to deal and to facilitate such tasks. However, we have identified that many of the shortcomings of the proposed technologies have been neglected by some authors, compromising the feasibility of including them into any proposed approach. In this study we aim at describing the most prominent approaches which relate manufacturing with knowledge representation. Furthermore some formal aspects of Ontology and Semantic Web technologies will be introduced, with the intention of present a general view that integrates research contributions which combine both approaches in an emerging approach called Semantic Manufacturing. © 2015 Elsevier Ltd.
