1. Hybrid Quaternions of Leonardo
ABSTRACT In this article, we intend to investigate the Leonardo sequence presenting the hybrid Leonardo quaternions. To explore Hybrid Quaternions of Leonardo, the priori, sequence of Leonardo, quaternions and hybrid numbers were presented. Soon after, its recurrence, characteristic equation, its relation with the Fibonacci quaternions, generating function,

2. How much do we know about the groundwater quality and its impact on Brazilian society today?
Resumo As águas subterrâneas são um recurso imprescindível para a sociedade e o meio ambiente no Brasil. Mais de 557 m3/s (17.5 km3/a) são extraídos através de 2.5 milhões de poços para atender a demanda nas cidades e no campo, gerando uma economia de R$ 56 bilhões ao ano (US$ 14 bilhões/ano). O aquífero tem função impar no ciclo hidrológico,

3. SPATIAL DEPENDENCE DEGREE AND SAMPLING NEIGHBORHOOD INFLUENCE ON INTERPOLATION PROCESS FOR FERTILIZER PRESCRIPTION MAPS
ABSTRACT Data interpolation is widely required in precision agriculture. However, its effectiveness is a function of the characteristics of the dataset, being necessary for the evaluation of several parameters. This study aimed to identify how the spatial interpolators, Kriging, and Inverse Distance Weighting, are influenced by the degree of spatial dependen

4. MEMORY COMPATIBILISM: PRESERVING AND GENERATING POSITIVE EPISTEMIC STATUS
RESUMO O debate epistemológico contemporâneo acerca do papel epistêmico da memória tem sido dominado pela disputa entre duas visões diferentes: o preservacionismo da memória e o gerativismo da memória. Enquanto o primeiro sustenta que a memória apenas preserva o status epistêmico já adquirido via outra fonte, o último defende que existem situaçõ

5. The Log-Odd Normal Generalized Family of Distributions with Application
Abstract: The normal distribution has a central place in distribution theory and statistics. We propose the log-odd normal generalized (LONG) family of distributions based on log-odds and obtain some of its mathematical properties including a useful linear representation for the new family. We investigate, as a special model, the log-odd normal power-Cauchy

6. Generation of Non-diffraction Vortex Beam and Its Application in Digital Communication
Abstract An axicon-frustum basin-type Bessel resonator is designed for generating non-diffraction vortex beams with opposite propagation directions under different conditions. Based on the theory of geometric optics, the principle of creating vortex beams is analyzed in this axicon-frustum basin-shaped resonant cavity. It is shown that a non-diffraction vort

7. Consumo de forragem por ovinos ingerindo grama missioneira gigante com ou sem acesso a amendoim forrageiro
RESUMO A grama missioneira gigante (Axonopus catharinensis Valls) é uma espécie forrageira que merece ser melhor investigada tanto pura como recebendo a inclusão de leguminosas. Objetivou-se avaliar o consumo de MS por ovinos pastejando grama missioneira gigante com ou sem acesso a pastos de amendoim forrageiro (Arachis pintoi cv. Amarillo). Para isso, fo

8. The Nadarajah-Haghighi Lindley distribution
Abstract: We define a new lifetime model based on compounding the Lindley and Nadarajah-Haghighi distributions. The proposed distribution is very competitive to other lifetime models. Some of its mathematical properties are investigated including generating function, mean residual life, moments, Bonferroni and Lorenz curves and mean deviations. We discuss th

9. Scenario reduction using machine learning techniques applied to conditional geostatistical simulation
Abstract One of the basic factors in mine operational optimization is knowledge regarding mineral deposit features, which allows to predict its behavior. This could be achieved by conditional geostatistical simulation, which allows to evaluate deposit variability (uncertainty band) and its impacts on project economics. However, a large number of realizations

11. Modeling and FPGA-based implementation of an efficient and simple envelope detector using a Hilbert Transform FIR filter for ultrasound imaging applications
Abstract Introduction Although the envelope detection is a widely used method in medical ultrasound (US) imaging to demodulate the amplitude of the received echo signal before any back-end processing, novel hardware-based approaches have been proposed for reducing its computational cost and complexity. In this paper, we present the modeling and FPGA impleme

12. Liver Damage Induced by Succinylacetone: A Shared Redox Imbalance Mechanism between Tyrosinemia and Hepatic Porphyrias
To show liver failure mediated by 5-aminolevulinic acid (ALA), a heme precursor accumulated in inborn and acquired porphyrias, rats were treated with succinylacetone methyl ester (SAME). Treated rats underwent the expected ALA accumulation in plasma, liver and urine as a result from inhibition of ALA dehydratase (ALAD) activity. The enzyme activity decreased
