Renewable diesel, or green diesel, is the biofuel with the fastest growing use in the world. Its use as a replacement for fossil diesel is important to reduce the impact of carbon emissions. Green diesel is formed by a mixture of hydrocarbons with a chemical composition similar to that of fossil fuel, making it a drop-in biofuel. Commercial processing employs hydrotreatment of vegetable oil, which, in addition to producing green diesel, can also be used to produce biofuel for aviation, bionaphtha ...

Scales measuring positive and negative symptoms in schizophrenia remain the primary mo Scales measuring positive and negative symptoms in schizophrenia remain the primary mode of assessing and diagnosing schizophrenia by clinicians and researchers. The scales are mainly used to monitor the severity of positive and negative symptoms and track treatment response in schizophrenics. Although these scales are widely used, quality as well as general utility of each scale varies. The quality is determined ...

This paper presents two methodologies for monitoring the service condition of diesel-engine lubricating oils on the basis of infrared spectra. In the first approach, oils samples are discriminated into three groups, each one associated to a given wear stage. An algorithm is proposed to select spectral variables with good discriminant power and small collinearity for the purpose of discriminant analysis classification. As a result, a classification accuracy of 93% was obtained both in the middle ( ...

We have previously described an immortal rat central-nervous-system progenitor cell line, AF5, which is able to exit the cell cycle and assume a differentiated state with neuronal properties. The phenotypic specification of differentiated AF5 cells, however, is not known. In the present study, when induced to differentiate by serum starvation in Neurobasal medium, AF5 cells down-regulate glial fibrillary acidic protein and up-regulate expression of β–III–tubulin, medium-molecular-weight neurofilament ...

The use of the Successive Projections Algorithm (VSPA) to select variables for building robust transferable Multiple Linear Regression (MLR) models is investigated. The robustness requirement is explicitly taken into account by introducing some spectra acquired by the slave instrument in the validation set that guides VSPA selection. The transfer samples are selected by the classic Kennard–Stone (KS) algorithm or a modified version of VSPA (SSPA) that operates across the rows of the instrumental response ...

The main aim of this work is to implement and evaluate the performance of a neural network-based model predictive control (MPC) applied to a fluid catalytic cracking (FCC) unit. The studies were carried out by dynamic simulation of a Kellogg Orthoflow F converter. The output signals were modified by random noise. From steady-state conditions, a sequence of step changes was imposed on the usual manipulated variables. Information on the process dynamics and interactions among variables is supplied by ...

The pyrolysis of vegetable oil waste is an alternative way to convert biomass into high-quality second-generation biofuels, with social, economic and environmental sustainability. The present work deals with the pyrolysis of oleic acid as a model compound and an industrial vegetable oil residue on CuNiAl mixed oxide catalysts, derived from layered double hydroxides. Reactions of the oils pre-adsorbed on the catalysts (catalyst:oil mass ratio of 5:1) were performed at 550 °C on a micro-pyrolysis system ...

Markers are regularly used to detect fraud and adulteration in fuel as well as to track products in a distribution chain. Herein, we tested the use of CdSe semiconductor fluorescent nanocrystals, quantum dots, as a new class of fuel markers. Quantum dots show bright fluorescence and they can be excited by light sources covering a broad spectral range, from ultraviolet up to the near infrared region. This class of markers presents great advantages over conventional ones, such as high detectability ...

Energy cane is a genotype derived from species of sugarcane (Saccharum officinarum and Saccharum spontaneum) with a lower sucrose content and higher fiber content for bioenergy purposes. It is a rustic plant that demands less fertile soils that do not compete with food crops. In this work, an analysis of energy cane bagasse pyrolysis products was performed, assessing the effect of reaction temperature and kinetic and thermodynamic parameters. Anhydrosugars, such as D-allose, were the primary compounds ...

The chemical recycling of poly(ethylene terephthalate) (PET) residues was performed via glycolysis with ethylene glycol (EG) over Mg-Fe and Mg-Al oxide catalysts derived from layered double hydroxides. Catalysts prepared using the high supersaturation method (h.s.c.) presented a higher surface area and larger particles, but this represented less PET conversion than those prepared by the low supersaturation method (l.s.c.). This difference was attributed to the smaller mass transfer limitations inside ...

Artificial Neural Networks (ANNs) constitute a technology that has recently become the focus of great attention. The reason for this is due mainly to its capacity to treat complex and nonlinear problems. This work consists of the identification and control of a fluid cracking catalytic unit (FCCU) using techniques based on multilayered ANNs. The FCC unit is a typical example of a complex and nonlinear process, possessing great interaction among the operation variables and many operational constraints ...

This communication shows the recipe for plasma-enhanced atomic layer deposition (PEALD) Al2O3 ultra-thin films with thicknesses below 40 nm. Al2O3 ultra-thin films were deposited by PEALD to improve the rubidium optically pumped atomic magnetometers’ (OPMs) cell lifetime. This requirement is due to the consumption of the alkali metal (rubidium) inside the vapor cells. Moreover, as a silicon wafer was used, an on-chip photodiode was already integrated into the fabrication of the OPM. The ALD parameters ...

La notion de corporéité s'inscrit au cœur d'une anthropologie philosophique où l'on distingue deux orientations, phénoménologique et scientifique. Celles-ci peuvent-elles se rejoindre au lieu de l'originaire? La « chair » du monde, au sens ontologique, et la genèse de l'homme dans l'évolution des vivants peuvent-elles s'ordonner au concept de structure? Mais la notion de structure du comportement dans l'analyse de la perception, de l'émotion, de l'expressivité, ne peut rendre compte de l'ipséité affective ...

La phenomenologie revele les modalites affectives comme modulations de la structure temporelle (Horizon-Instant) de l'existence (Cf. le texte de Heidegger sur l'ennui, 1929). Mais ce qui specifie la temporalite propre dans sa dimension relationnelle, c'est la rencontre: elle suscite l'axe bipolaire d'amplitude ou du repli de l'existence (plaisir-douleur, joie-tristesse, selon les etats: emotion, passion, sentiment). La rencontre porte le signe originel d'une polarite affective dont le paradigme fondateur ...
