title: Differential expression analysis to aluminum toxicity in Citrus x limonia Osbeck

description: Here we deliver the Differential gene expression on genes response to aluminum toxicity in <em>Citrus</em> x<em> limonia. </em>Root apices of ‘Mandarin’ lime plants grown for 60 days in nutrient solutions either with 1480 mM Al<sup>3+</sup> or 0 mM Al<sup>3+</sup> were analyzed by RNA-seq. Clean reads were mapped to the sweet orange (<em>Citrus sinensis</em>) genome (Xu et al. 2013). Gene expression levels were calculated by CPM (Counts per million) reads. We used HTSeq ver. 0.6.1 (Anders et al. 2015) CPM estimation.

title: Synthesis of BaTIO3 and SrTIO3 by microwave assisted hidrotermal method (mah) using anatase as titanium precursor

description: In this work barium titanate (BT) and strontium titanate (ST) were prepared by Microwave-Assisted Hydrothermal (MAH) method, using a Ti precursor different from those shown in the literature and various concentrations (1, 3 e 6 mol L-1) of KOH mineralizer. As a titanium precursor, an anatase complex with hydrogen peroxide were used. For the precursors of barium and strontium, chlorides were used. The materials resulting from the synthesis processes were characterized in room temperature by different techniques as like: X-Ray Diffraction (XRD), micro-Raman Spectroscopy, UV-Vis, Scanning Electron Microscopy (SEM) and Photoluminescence (PL). The results show that there were differences in crystallinity, morphology, number of phases and photoluminescence depending on the concentration of the mineralizer.

title: Thermogravimetric and spectroscopic study (TG–DTA/FT–IR) of activated carbon from the renewable biomass source babassu

description: Activated carbons (ACs) with well–developed microstructure and high microporosity were obtained from biomass by potassium hydroxide activation. The preparation process consisted in producing carbon materials in the ratios of activating agent to raw material 70:30, 50:50, 30:70 and 25:75 (w/w) characterized by thermal analysis coupled to spectroscopy (TG–DTA / FT–IR), scanning electron microscopy (SEM), N2 adsorption isotherms at –196 ºC and activation isotherm at 500 and 600 ºC for 3.0 h. Specific surface areas (SBET) within 728 and 1712 m2 g-1 and (Smic) within 1054 and 1923 m2 g-1 were obtained, while the micropores surface area was calculated using the Dubinin-Astakhov (DA) equation and the pore size distribution calculated from density functional theory (DFT) was found to be in the range 1.09 – 1.77 nm. Adsorption isotherms were fitted using Langmuir and Freundlich non–linear models and the adsorption capacity determined for methylene blue dye was between 27.13 and 459.20 mg g-1.

title: SYNTHESIS, THERMAL STUDIES AND CONVERSION DEGREE OF DIMETHACRYLATE POLYMERS USING NEW NON-TOXIC COINITIATORS

description: The aim of this paper is to replace toxic coinitiators (tertiary amines) by non-toxic compounds such as glycerol and inositol (polyalcohol) in dimethacrylate resins. For this purpose, mid infrared spectroscopy (MIR) was used to calculate the monomers' degree of conversion (�); as well as simultaneous Thermogravimetric Analysis – Differential Thermal Analysis (TGA-DTA) and Differential Scanning Calorimetry (DSC) were conducted to evaluate thermal stability, degradation steps, and thermal events. The use of different initiator systems did not modify the thermal events or the thermal stability of each of the dimethacrylate resins. Results show a substitution of system 2 (toxicity) by system 3 (low toxicity), which had a good conversion velocity and total conversion in some monomers, is plausible.

title: QUANTIFICATION OF SOIL CO2 EMISSIONS IN TWO FORESTED AREAS UNDER DIFERENT REGENERATION STAGES IN ATLANTIC FOREST

description: In order to quantify emission rates of CO2 through the soil from the Atlantic forest under different regeneration stages, two areas located in Rio Claro(SP) were studied. In the first area the forest is regenerated (Plot 23) and the average CO2 emission is 1.91 mmol m-2s-1, while in the recently planted area (Plot 15), the average emission is 1.38 mmol m-2s-1. The CO2 emissions are fairly correlated to soil moisture (r=0.53, P=&lt;0.0001), C/N ratio (r=0.27, p&lt;0.05) and time of measurement (r=0.33, p&lt;0.05). Multiple linear regression models developed are better to reproduce CO2 soil emissions in recently planted area.

title: QUANTUM DOT-SENSITIZED SOLAR CELLS

description: Quantum dot solar cells (QDSC) have been subject of extensive research in recent years. QDSC, as a promising alternative to existing solar cells, are among the candidates for next-generation photovoltaic devices that require low cost, high efficiency, so that quantum dots stand out for their unique features and versatile desirable on photovoltaic systems. The rapid development of QDSC provided a significant increase in energy conversion efficiency, which was certified for the first time in 2010 as 2% then being currently as 11.3%, according to the National Renewable Energy Laboratory (NREL). This paper presents a review of the quantum dot-sensitized solar cells and the major advances reported concerning these cells, besides other types of cell architectures involving quantum dots.

title: SELECTIVE SYNTHESIS OF PEG-MONOESTER USING CESIUM HETEROPOLY ACID AS HETEROGENEOUS CATALYST

description: Esterification of oleic acid with polyethylene glycol 600 (PEG-600) to produce polyethylene glycol monooleate (PEG-monooleate) and polyethylene glycol dioleate (PEG-dioleate) as by-product has been studied in the presence of heterogeneous acid catalysts, i.e. cesium heteropoly acid (Cs HPA). The results are compared with those obtained from a classical homogeneous acid catalyst; p-toluene sulphonic acid (p-TSA). The reaction was conducted under nitrogen flow with vigorous stirring at 130 ºC and 150 ºC. The catalyst loading kept at 4% and the reaction was monitored at 1, 3, 7 and 24 hours. Reaction samples were analyzed using high performance liquid chromatography (HPLC) equipped with evaporative light scattering detector (ELSD). The results obtained showed that Cs HPAs exhibit 100% selectivity of PEG-monooleate from the first hour until 24 hours. However, this does not happen with homogeneous p-TSA, where formation of by-product; PEG-dioleate is observed in the initial stage. It is also showed that the mole ratio is the most important parameter not only to produce high yield of monoester but also to maintain it along the reaction. Chemical and physical properties of catalysts were characterized using Thermal Gravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), Fourier Tranmittance Infra-Red (FTIR), ammonia temperature programmed desorption (NH3-TPD) and X-ray Diffraction (XRD).

title: GLOBAL AND LOCAL ELECTROPHILIC POWER INDICES FOR THEORETICAL STUDY OF THE CHEMICAL REACTIVITY: APPLICATION TO α,β-UNSATURATED CARBONYL DERIVATIVES

description: In this study two new global descriptors for chemical reactivity are proposed, namely the electrophilic power and nucleophilic power. These have been developed by performing the normalization of the local electrophilic power and local nucleophilic power respectively, which were recently proposed elsewhere. In particular, the usefulness of both global and local electrophilic power was evaluated by studying the chemical reactivity of six series of α,β-unsaturated carbonyl compounds whose experimental reactivity measures toward the nucleophile glutathione are available. It was observed in the majority of the cases the global and local electrophilic powers work as better than the popular global and local electrophilicity indices, respectively.

title: RAPID SPECTROPHOTOMETRIC DIFFERENTIATION BETWEEN PALM OIL BIODIESEL AND RED DYE ADDED TO DIESEL FUEL

description: Currently, there are two mixtures of biodiesel/diesel fuel sold in Brazil: BX/S500 and BX /S10 (X = volume/volume biodiesel percentage; S500 and S10 = sulfur content in diesel fuels - 500 ppm and 10 ppm, respectively). In order to differentiate these mixtures, red dye is added to diesel oil as required by the National Agency for Petroleum, Natural Gas and Biofuels (ANP), regulatory agency in Brazil. Since the palm oil biodiesel has also a reddish color, mixing this product with diesel fuel leads to difficulty in visual differentiation of the mixtures BX/S500 and BX/S10. We propose the use of UV-Vis spectrophotometry, which is a low cost, simple and rapid technique. Spectra obtained for different mixtures show that qualitative distinction is possible. For quantification of red dye in the presence of palm oil biodiesel, the method is limited when dye is present in low concentrations (&lt; 0.1 mg L-1) due to matrix effects. The method showed good repeatability of the absorbance responses, wide linear dynamic range (0.02 mg L-1 to 40.00 mg L-1) and low limits of detection and quantification (0.006 mg L-1 and 0.019 mg L-1, respectively).

title: Repeatmasker Tables Custom Part 1

description: We annotated repeats in assemblies through two rounds of annotation with RepeatMasker4.1.0 (Smit et al. 2020), the first round used custom repeat libraries generated by RepeatModeler2 for each respective assembly and with search engine “ncbi” and option -xsmall. We then converted the softmasked assembly resulting from the first RepeatMasker round to a hardmasked assembly using the lc2n.py script (https://github.com/PdomGenomeProject/repeat-masking), and re-ran RepeatMasker on the hard-masked assembly with RepeatMasker’s internal arthropod repeat library and species “Arthropoda”. We then merged RepeatMasker output tables from both runs to summarize the abundance of RE categories.<br><br><br><i>Authors: John S.

title: MATHEMATICAL MODEL OF CATALYTIC PROCESSES AT MODIFIED ELECTRODES

description: A mathematical modeling of electrocatalytic processes taking place at modified electrodes is discussed. In this paper we obtained the approximate analytical solutions for the nonlinear equations under non steady state conditions using homotopy perturbation method. Simple and approximate polynomial expressions for the concentration of reactant, product and charge carrier were obtained in terms of diffusion coefficient and rate constant. In this work the numerical simulation of the problem is reported using Scilab program. In this manuscript analytical results are compared with simulation results and satisfactory agreement is noted.
