a frequency based assignment model for congested transit networks with strict capacity constraints characterization and computation of equilibria
Transportation Research Part B-methodological, 2006Co-Authors: M Cepeda, Roberto Cominetti, Michael FlorianAbstract:Abstract This paper concerns a frequency-based route choice model for congested transit networks, which takes into account the consequences of congestion on the predicted flows as well as on the expected waiting and travel times. The paper builds on the results presented in Correa [Correa, J., 1999. Asignacion de flujos de pasajeros en redes de transporte publico congestionadas. Engineering thesis, U. de Chile, Santiago] and Cominetti and Correa [Cominetti, R., Correa, J., 2001. Common-lines and passenger assignment in congested transit networks. Transportation Science 35(3), 250–267], extending these to obtain a new characterization of the equilibria which allows us to formulate an equivalent optimization problem in terms of a computable gap function that vanishes at equilibrium. This new model formulation can deal with flow dependent travel times and is a generalization of the previously known strategy (hyperpath) based transit network equilibrium models. The approach leads to an algorithm which has been applied successfully on large scale networks. Computational results for transit networks originating from practice demonstrate the applicability of the proposed approach.

Contradictions that Endure: Family Norms, Social Reproduction, and Rafael Correa's Citizen Revolution in Ecuador
Politics & Gender, 2012Co-Authors: Amy LindAbstract:Upon entering office in 2007, socialist Rafael Correa launched his Citizen Revolution in Ecuador, with the aim of establishing a postneoliberal order. His antineoliberal political discourse called for a “living well” (i.e., buen vivir in spanish; sumaq kawsay in Quichua) development model that favored solidarity over competition and sustainability over economic growth. It also called for increased political inclusivity and a form of redistribution that reaches a broader range of citizens. In line with other Latin American populist-socialist leaders, such as Hugo Chavez of Venezuela and Evo Morales of Bolivia, Correa claimed that his revolution “has a woman's face.” Yet personally, Correa is a devout Catholic and trained economist who opposes abortion and homosexuality and favors a traditional familial model—one that reinforces a notion of “modern economic man” that is both Eurocentric and heteronormative.

one step biofabrication of copper nanoparticles from aegle marmelos Correa aqueous leaf extract and evaluation of its anti inflammatory and mosquito larvicidal efficacy
RSC Advances, 2014Co-Authors: Gangadhara Angajala, Pasupala Pavan, Radhakrishnan SubashiniAbstract:The present investigation is focused on the biofabrication of copper nanoparticles (CuNPs) using Aegle marmelos Correa aqueous leaf extract as a reducing agent. The synthesized CuNPs were successfully characterized by UV-Vis spectroscopy, FT-IR, XRD, SEM and AFM studies. The phytosynthesis of CuNPs was done at room temperature (30 °C) for 24 h and at 60 °C, and 100 °C for 4 h. The green synthesis of spherical-shaped CuNPs biofabricated from Aegle marmelos Correa with a face centered cubic structure showed average particle sizes of 50–100 nm and 100–200 nm, which is inconsistent with the particle size calculated by the XRD Scherer equation. We further explored the in vitro anti-inflammatory and mosquito larvicidal efficacy of biosynthesized CuNPs with crude leaf extracts of Aegle marmelos Correa against three blood feeding parasites, namely, Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. A comparative study was performed on the bioefficacy of different sizes of CuNPs coated with Aegle marmelos Correa with that of CuNPs synthesized by a chemical reduction method using NaBH4. The results obtained clearly show that CuNPs (50–100 nm) of Aegle marmelos Correa possess good anti-inflammatory efficacy, with a percentage inhibition of 78.90 ± 1.23 for the membrane stabilization method and 74.18 ± 1.48 for the albumin denaturation method at a concentration of 100 μg ml−1, which is comparable to standard Aceclofenac, and better larvicidal activity against Anopheles stephensi with an LC50 of 500.06 ppm, when compared to crude leaf extracts of Aegle marmelos Correa and that of standard Temephos.

in vitro anti inflammatory and mosquito larvicidal efficacy of nickel nanoparticles phytofabricated from aqueous leaf extracts of aegle marmelos Correa
Acta Tropica, 2014Co-Authors: Gangadhara Angajala, R Ramya, Radhakrishnan SubashiniAbstract:Abstract In recent years there is a tremendous growth in the interdisciplinary world of nanotechnology across the globe and emergence of its potential applications remains as a big revolution to the industry. Fusion of green nanotechnology and medicine represents one of the major breakthroughs of modern science with the aim of developing nanomaterials for diagnosis, treatment, prevention of various diseases and overall improving health for the beneficial of mankind. In the present study phytofabrication of nickel nanoparticles (nickel NPs) was carried out by using indigenous Aegle marmelos Correa aqueous leaf extracts as a reducing, stabilizing and capping agents. Nickel NPs were characterized by UV-spectroscopy, FTIR, XRD, SEM, AFM and TGA studies. Phytosynthesis of nickel NPs was monitored both at room temperature (25 °C) and at 60 °C for 5 h. The green synthesis of triangular shape nickel NPs phytofabricated from A. marmelos Correa aqueous leaf extracts having face centered cubic structure showing an average particle size of 80–100 nm which is in consistent with the particle size calculated by XRD Scherer equation. We further explored and compared nickel NPs of A. marmelos Correa with crude leaf extracts of A. marmelos Correa for its in-vitro anti-inflammatory and mosquito larvicidal efficacy against three blood feeding parasites. The results obtained clearly gives an idea that nickel NPs of A. marmelos Correa (NiNPs of AmC) possess an enhanced anti-inflammatory and larvicidal activity when compared to crude leaf extracts of A. marmelos Correa.
