Role of empowerment and identification with work teams in innovation climate
(Fundacao Getulio Vargas, Escola de Administracao de Empresas de Sao Paulo, 2020)
Acceso abierto
Several studies argue that an organizational climate oriented to promote innovation generates greater competitiveness in companies. However, very few researchers have explored the factors that lead to the formation of ...
TiO2:Cex onto Al Clays for Photocatalytic Solar Water Disinfection
(Hindawi, 2020)
Acceso abierto
A novel methodology was employed to prepare new nanocomposites with photocatalytic properties based on Ce-doped TiO2 nanoparticles arranged over a layered silicate. The catalysts were porous materials formed by exfoliated ...
Mixing design for optimizing ultrasound-assisted extraction of phenolic components and anthocyanins from blue berries and grape marc
(Taylor & Francis, 2020)
Acceso restringido
Waste from fruit processing can be used for obtaining additives as colorants and antioxidant compounds by extraction processes. Despite there are many works optimizing parameters as temperature and solvent concentration ...
Software Curriculum Transformation at the University Level
(IEEE, 2020)
Acceso restringido
Many software-related degrees exist, and a diversity of programs makes it difficult for candidates to choose where they wish to study. Selecting the wrong program costs students time, money, and considerable effort. Though ...
Synthesis, Spectroscopic Characterization, Structural Studies, and in Vitro Antitumor Activities of Pyridine-3-carbaldehyde Thiosemicarbazone Derivatives
(Hindawi, 2020)
Acceso abierto
Eight new thiosemicarbazone derivatives, 6-(1-trifluoroethoxy)pyridine-3-carbaldehyde thiosemicarbazone (1), 6-(4'-fluorophenyl)pyridine-3-carbaldehyde thiosemicarbazone (2), 5-chloro-pyridine-3-carbaldehyde thiosemicarbazone ...
Physicochemical characterization and oxidative stability of microencapsulated edible sacha inchi seed oil by spray drying
(Consejo Superior de Investigaciones Científicas, 2020)
Acceso abierto
The aim of this work was to obtain sacha inchi oil (SIO) microcapsules from two different spe-cies, Plukenetia volubilis L. (SIVO) and Plukenetia huayllabambana L. (SIHO), using different biopolymers as wall materials and ...
Development of a Fuzzy Logic-Based Solar Charge Controller for Charging Lead–Acid Batteries
(Springer, 2020)
Acceso restringido
The design and implementation of a solar charge controller for lead–acid batteries is intended to supplement a component of the water purification module of the water treatment unit for natural disaster relief. This unit ...
Indole-3-carbaldehyde Semicarbazone Derivatives: Synthesis, Characterization, and Antibacterial Activities
(Hindawi Limited, 2020)
Acceso abierto
The two-dimensional NMR (in acetone-d6) spectral data revealed that the molecules 1 and 2 in solution are in the cisE isomeric form. This evidence is supported by DFT calculations at the B3LYP/6-311++G(d,p) level of theory ...
Semantic Segmentation of Weeds and Crops in Multispectral Images by Using a Convolutional Neural Networks Based on U-Net
(Springer, 2020)
Acceso restringido
A first step in the process of automating weed removal in precision agriculture is the semantic segmentation of crops, weeds and soil. Deep learning techniques based on convolutional neural networks are successfully applied ...
Water treatment plant prototype with ph control modeled on fuzzy logic for removing arsenic using fe(VI) and fe(III)
(Multidisciplinary Digital Publishing Institute, 2020)
Acceso abierto
This study proposes a fuzzy control strategy embedded in a Siemens IoT2040 gateway developed for removing inorganic arsenic from synthetic underground water in a treatment plant prototype. The prototype is used to dose a ...
