Title: Prediction of compression strength of high performance concrete using artificial neural networks
Authors: Torre, A.; Garcia, F.; Moromi, Isabel; Espinoza, P.; Acuña, L.
Abstract: High-strength concrete is undoubtedly one of the most innovative materials in construction. Its manufacture is simple and is carried out starting from essential components (water, cement, fine and aggregates) and a number of additives. Their proportions have a high influence o...
Title: Equivalence between p-cyclic quasimonotonicity and p-cyclic monotonicity of affine maps
Authors: Ocaña, Eladio; Cotrina, John; Bueno, Orestes
Abstract: We prove that the notions of -cyclic quasimonotonicity and -cyclic monotonicity are equivalent for affine maps defined on Banach spaces. First this is done in a finite dimensional space by using the index of asymmetry for matrices defined by J.-P. Crouzeix and C....
Title: Fabrication of ultra-sharp tips from carbon fiber for scanning tunneling microscopy investigations of epitaxial graphene on 6H-SiC(0001) surface
Authors: Morán Meza, José Antonio; Lubin, Christophe; Thoyer, F.; Villegas Rosales, Kevin Amilcar; Gutarra Espinoza, Abel Aurelio; Martin, F.; Cousty, Jacques
Abstract: The fabrication of ultra-sharp tips from carbon fiber (CF), which are mounted on a qPlus probe for combined dynamic scanning tunneling microscopy (STM) and frequency modulation atomic force microscopy (FM-AFM) experiments, is reported. The carbon fiber tips were electrochemically e...
Title: Influence of the spray pyrolysis seeding and growth parameters on the structure and optical properties of ZnO nanorod arrays
Authors: Rodríguez, Juan; Feuillet, Guy; Donatini, Fabrice; Onna, Diego; Sanchez, Luis; Candal, Roberto J.; Marchi, María Claudia; Bilmes, Sara A.; Chandezon, Frédéric
Abstract: ZnO nanorods (NRs) were grown on fluorine doped tin oxide (FTO) substrates at low temperatures (90 °C) from Zn2+ precursors in alkaline media previously seeded with ZnO nanoparticles. These were deposited onto the FTO substrate heated at 350 °C by spray pyrolysis of&...
Title: A refined FSDT for the static analysis of functionally graded sandwich plates
Authors: Mantari, J. L.; Granados, E. V.
Abstract: This paper presents a static analysis of functionally graded plates (FGPs) by using a new first shear deformation theory (FSDT). This theory contains only four unknowns, with is even less than the classical FSDT. In this paper a simply supported FG square sandwich&#x...
Title: Synthesis and Characterization of ZnO Nanorod Films on PET for Photocatalytic Disinfection of Water
Authors: Sanchez, Luis; Guz, Lucas; García, Pilar; Ponce, Silvia; Goyanes, Silvia; Marchi, María Claudia; Candal, Roberto J.; Rodríguez, Juan
Abstract: ZnO nanorods (ZnO NRs) were grown on ZnO seeded polyethylene tert-phtalate (PET) substrates obtained from recycled soda bottles at low temperatures (90 °C) from Zn2+ precursors in alkaline aqueous solution. The ZnO seeds were deposited on the PET substrates by spray gel&#...
Title: Helminth Egg Removal Capacity of UASB Reactors under Subtropical Conditions
Authors: Yaya Beas, Rosa Elena; Ayala Limaylla, Christian; Kujawa Roeleveld, Katarzyna; Van Lier, Jules B.; Zeeman, Grietje
Abstract: This research was conducted to study the anaerobic sludge filtration capacity regarding helminth egg removal in upflow anaerobic sludge blanket (UASB) reactors. Two 25 L lab-scale UASB reactors were operated at an ambient temperature which varied between 17.1 and 28.6 °C. ...
Title: Defining fishing spatial strategies from VMS data: Insights from the world's largest monospecific fishery
Authors: Joo, Rocio; Salcedo, Omar; Gutierrez, Mariano; Fablet, Ronan; Bertrand, Sophie
Abstract: Understanding the spatiotemporal behavior of fishermen at the fleet scale is key for defining effective strategies for fisheries management. Here we classify the spatial patterns exhibited by fishing trip trajectories in the world's largest monospecific fishery, the Peruvian anchovy...
Title: Influence of parameter values on the oscillation sensitivities of two p53–Mdm2 models
Authors: Cuba, Christian E.; Valle, Alexander R.; Ayala-Charca, Giancarlo; Villota, Elizabeth R.; Coronado, Alberto M.
Abstract: Biomolecular networks that present oscillatory behavior are ubiquitous in nature. While some design principles for robust oscillations have been identified, it is not well understood how these oscillations are affected when the kinetic parameters are constantly changing or are not&...
Title: Preparation by co-precipitation of Ce–Mn based catalysts for combustion of n-hexane
Authors: Picasso Escobar, Gino Italo; Cruz, Rómulo; Sun Kou, María del Rosario
Abstract: Catalysts for combustion of n-hexane, based on Ce-Mn mixed oxides with different Ce/Mn molar ratios ranging from 0.5 to 2, have been prepared by co-precipitation at constant pH with aging times of 4, 18 and 24 h. XRD patterns of the mixed oxides showed ...
