Adubação fosfatada corretiva para cultura do milho.
No full textO experimento foi conduzido durante três anos consecutivos, em condições de campo, em um Latossolo Vermelho distrófico argiloso, com o objetivo de verificar os efeitos da adubação fosfatada corretiva na produção de grãos de milho e em algumas características químicas do solo. Foram utilizadas seis doses de termofosfato magnesiano (0 – 180 – 270 – 360 – 450 – 540 kg ha-1 de P2O5), aplicadas no primeiro ano, a lanço com posterior incorporação com grade. Verificou-se que a adubação fosfatada corretiva promoveu incrementos significativos na produção de grãos de milho e nos teores de P no solo. De maneira geral, doses superiores a 270 kg ha-1 de P2O5 foram eficientes até o terceiro ano agrícola. Uma produção relativa de 90% esteve associada a uma concentração de P no solo ao redor de 15 mg dm-3 . A dose mais elevada de termofosfato promoveu, nos dois primeiros anos, um aumento significativo na saturação por bases, valor de pH e teores de Ca e Mg no sol
The ground state tunneling splitting of malonaldehyde: Accurate full dimensional quantum dynamics calculations
No full textCoutinho-Neto MD, Viel A, Manthe U. The ground state tunneling splitting of malonaldehyde: Accurate full dimensional quantum dynamics calculations. Journal of Chemical Physics. 2004;121(19):9207-9210.Benchmark calculations of the tunneling splitting in malonaldehyde using the full dimensional potential proposed by Yagi [J. Chem. Phys. 115, 10647 (2001)] are reported. Two exact quantum dynamics methods are used: the multiconfigurational time-dependent Hartree (MCTDH) approach and the diffusion Monte Carlo based projection operator imaginary time spectral evolution (POITSE) method. A ground state tunneling splitting of 25.7+/-0.3 cm(-1) is calculated using POITSE. The MCTDH computation yields 25 cm(-1) converged to about 10% accuracy. These rigorous results are used to evaluate the accuracy of approximate dynamical approaches, e.g., the instanton theory. (C) 2004 American Institute of Physics.

Variability and spatial distribution of hydrodynamic properties in soil with preserved caatinga
No full textThe functions of soil water retention and hydraulic conductivity are indispensable for the characterization and modeling of the infiltration and water transfer processes in the vadose zone. In the case of the Brazilian semi-arid region, characterized by the scarcity of water resources, there is a lack of information on the hydrodynamic properties of the soil. Also, these properties have numerous factors of variability, requiring the characterization of their magnitude and distribution in space. This research presents an analysis of the infiltration process and the hydrodynamic properties of the soil under native Caatinga forest, observing its spatial distribution. This vegetation is typical of the Brazilian semi-arid region. One developed a 48-point grid in an area of approximately 875 m2, and applied on it the Beerkan methodology. The analyzes were performed based on the application of the BEST-Slope algorithm and statistical measures of the position, dispersion, and adherence tests. The results showed medium to high variability indices for the hydrodynamic properties, with random spatial distribution, despite the verification of a homogeneous texture in the area. Thus, it was found that the soil structure was predominant in the processes of water infiltration

Semantic Search of Mobile Applications Using Word Embeddings
No full textThis paper proposes a set of approaches for the semantic search of mobile applications, based on their name and on the unstructured textual information contained in their description. The proposed approaches make use of word-level, character-level, and contextual word-embeddings that have been trained or fine-tuned using a dataset of about 500 thousand mobile apps, collected in the scope of this work. The proposed approaches have been evaluated using a public dataset that includes information about 43 thousand applications, and 56 manually annotated non-exact queries. Our results show that both character-level embeddings trained on our data, and fine-tuned RoBERTa models surpass the performance of the other existing retrieval strategies reported in the literature
Embedding Reservoir Physics into Machine Learning
No full textThe aim of this thesis is to explore and develop proxy models for a petroleum reservoir numerical simulator based on scientific machine learning methods. Numerical reservoir simulation is an essential tool used in all stages of petroleum reservoir exploitation. Several technical studies are performed using these simulations, supporting many business decisions. These simulations are computationally expensive, and the complexity of the analysis may require thousands of simulations. An active research area is searching for a proxy model which could estimate the simulation outputs with a fraction of its computational cost.
We developed the Embed to Control and Observe method based on a convolutional autoencoder and the control system approach with physical loss functions. We showed our proxy model���s potential by applying it to three reservoir models. The last two models contained non-active grid blocks, which most real reservoir simulation models also have. To overcome this, we introduce the use of partial convolutional layers in reservoir simulation applications. The error obtained on our application are considerably low, so a reliable proxy can be obtained by applying the proposed method.
Physics Informed Neural Network has emerged as a powerful scientific machine learning tool. We developed a partial differential equation solver for hyperbolic problem that can automatically handle discontinuities. Our method can learn and localize the application of artificial viscosity during the neural network training procedure. We solved the Inviscid Burger���s equation and the Buckley-Leverett problem. The method can potentially be applied to solve other hyperbolic PDE systems. We also formulate a two-dimensional two-phases reservoir simulation PDE set of equations to be used on the Physics Informed Neural Network framework.
The significance of this study is that it shows the development and application of machine learning techniques associated with physical knowledge of the fluid flow phenomenon. These techniques have the potential to provide an inexpensive and reliable prediction of essential reservoir simulation outputs for the petroleum industry
Nitrogen fertilization management in no-tillage maize with different winter crops.
No full textThe nitrogen (N) utilization by maize grown in a no-tillage system is dependent on the quality of the preceding crop residues, which may promote differences in N fertilization efficiency with respect to time. Thus, the purpose of this study was to evaluate the nutritional state, dry matter production and grain yield of maize grown in a clayey soil (Typic Acrustox) under a no-tillage system. The split-plot experimental design was set up in randomized complete blocks with three replications, in which the main plot was treated with different N application strategies and the split-plots were planted with winter crops (soybean and maize). The fertilizer strategies (rate: 120 kg ha-1 of N) used were as follows: (0 ? 0), (20 ? 100), (60 ? 60), (120 ? 0) and (0 ? 120), with the first number corresponding to the rate of N (kg ha-1) applied before planting and the second number corresponding to the top dressing rate (V4-5 stage). Nitrogen fertilization raised the N content (in shoots and leaves) and maize yield (in the shoot dry matter and grain). The maize grown after soybean had both greater N concentrations and production (dry matter and grain) relative to the maize grown after maize. Applying 120 kg ha-1 N did not significantly affect the evaluated variables, regardless of the winter crop
Coelho Neto Canibal: Pseudônimos shakespearianos e literatura licenciosa no Brasil (1890-1940) / Coelho Neto Cannibal: Shakespearean pseudonyms and licentious literature in Brazil (1890-1940)
No full textResumo: Este trabalho estuda a trajetória do pseudônimo shakespeariano Caliban, adotado pelo escritor Henrique Coelho Neto (1864-1934), em 1890, para veicular literatura licenciosa nos impressos. Acompanhamos o pseudônimo desde sua estreia até sua última aparição no mundo editorial na década de 1940. Para levar a cabo a tarefa, consultamos os livros publicados por Caliban e investigamos sua atuação na imprensa periódica por meio da consulta online dos jornais na Hemeroteca Digital Brasileira. Caliban foi um autor de sucesso e parte desse reconhecimento vinha da origem erudita de seu nome. O filtro shakespeariano era crucial para a aceitação dessa literatura nos circuitos letrados, mas muitos a consideravam como mera pornografia. A literatura de Caliban revela um Coelho Neto moderno, contestador e inovador que foi esquecido pela tradição crítica.Palavras-chave: Coelho Neto; William Shakespeare; Caliban; literatura licenciosa.Abstract: This work studies the trajectory of the Shakespearean pseudonym “Caliban”, adopted by writer Henrique Coelho Neto (1864-1934) in the 1890s to convey licentious literature in print. We follow the pseudonym from its debut until its last appearance in the publishing world in the 1940s. To carry out the task, we consulted the books published by Caliban and investigated his performance in the periodic press through online consultation of newspapers in the Hemeroteca Digital Brasileira. Caliban was a successful author and part of that recognition came from the erudite origin of his name. The Shakespearean filter was crucial for the acceptance of this literature in literary circuits, but many considered it as mere pornography. Caliban’s literature reveals a modern, challenging and innovative Coelho Neto who has been overlooked by critical tradition.Keywords: Coelho Neto; William Shakespeare; Caliban; licentious literature
Megistops adiae Clark & Lillrose & Belo Neto 2013, new species
No full text<i>Megistops adiae</i>, new species <p>(Figures 18, 37, 45)</p> <p> <b>Diagnosis.</b> The large, apically truncate and bifurcate spur at the apex of each hind tibia is alone sufficient to distinguish this from all other chrysomelid species known to occur in the Cayman Islands. For specimens in which the position of the legs makes this character difficult to see, the large, nearly contiguous eyes, in combination with the greatly enlarged hind femora and essentially impunctate elytra, will also quickly enable identification. Similarly colored species of <i>Megistops</i> elsewhere in the West Indies are <i>M. bahamensis</i> Blake from the Bahamas, <i>M. parvula</i> Blake from Jamaica, and <i>M. tabebuiae</i> Blake from Cuba. In comparison with <i>M. adiae</i>, the elytral markings of well-marked specimens of <i>M. bahamensis</i> are less irregular in shape, and the aedeagus is much more arcuately broadened before the apex. The aedeagus of <i>M. parvula</i> is more similar to that of <i>M. adiae</i>, but the pale areas of the body are reddish brown instead of yellowish brown, the elytral markings are much smaller, the anterior marking sometimes being entirely absent, and the hind femora are pale (femora largely piceous in <i>M. adiae</i>, except for in the pale specimen from Grand Cayman). The aedeagus of <i>M. tabebuiae</i> is also similar to that of <i>M. adiae</i>, although Blake (1937) illustrated the sclerotized orificial covering as being much wider. The venter of <i>M. tabebuiae</i> is described as being yellowish or reddish brown. In <i>M. adiae</i>, the venter and hind femora are largely piceous (except for in the palely marked specimen from Grand Cayman).</p> <p> <b>Description of male.</b> Form elongate oval, narrower in front than behind; length 3.0 mm; width 1.7 mm.
