1. Microbial activity and studies on excavated megalithic micaceous potsherds from Peninsular India
Abstract The abundantly available mica flakes were added in raw materials to manufacture pottery in Central Peninsular India during the early Iron Age (700-300 BCE) for storage and glittering. The micaceous potsherds from the excavated megalithic site of Nagpur were studied for their composition, manufacturing techniques, microstructural features, microbial

2. MULTILEVEL NONLINEAR MIXED-EFFECTS MODEL AND MACHINE LEARNING FOR PREDICTING THE VOLUME OF Eucalyptus SPP. TREES
ABSTRACT Volumetric equations is one of the main tools for quantifying forest stand production, and is the basis for sustainable management of forest plantations. This study aimed to assess the quality of the volumetric estimation of Eucalyptus spp. trees using a mixed-effects model, artificial neural network (ANN) and support-vector machine (SVM). The datab

3. Editorial Comment: Robotic versus other nephroureterectomy techniques: a systematic review and meta-analysis of over 87,000 cases
ABSTRACT Purpose Preoperative computed tomography or magnetic resonance (MR) imaging are commonly used for radiological evaluation of renal cell carcinoma (RCC) before radical nephrectomy or nephron sparing surgery(NSS). This study aimed to assess the role of MRI for predicting postoperative renal function by preoperative estimation of renal parenchymal vo

4. Estimation of soil phosphorus availability via visible and near-infrared spectroscopy
ABSTRACT: Spectroscopic techniques have great potential to evaluate soil properties. However, there are still questions regarding the applicability of spectroscopy to analyze soil phosphorous (P) availability, especially in tropical soils with low nutrient contents. Therefore, this study evaluated the possibility to estimate P availability in soil and its po

5. Uncertainty estimation in hydrodynamic modeling using Bayesian techniques
RESUMO A avaliação de incertezas tem emergido como estudo primordial para se conhecerem os efeitos dos erros inerentes aos processos de modelagem de perfis de escoamento de vazões de cheia, de natureza aleatória e epistêmica, presentes em dados de entrada como vazões e topobatimetria, na estrutura e parametrização dos modelos matemáticos utilizados

6. ESTIMATING VEGETATION VOLUME OF COFFEE CROPS USING IMAGES FROM UNMANNED AERIAL VEHICLES
ABSTRACT Tree crops, such as Arabica coffee (Coffea arabica L.), present enormous technical challenges in terms of pesticide application. The correct deposition and distribution of the active ingredient throughout the aerial part of these plants depends on knowledge of the canopy volume, but manually determining this volume is time consuming and imprecise. T

7. Is the colon mucosa affected by ten days of gastric restriction in an animal model?
Abstract Purpose To identify whether the colon mucosa is affected by ten days of gastric restriction in an animal model. Methods An experimental model of gastric restriction was devised using rats. The animals were submitted to surgical gastrostomy, and a cylindrical loofah was inserted into the stomach. We studied 30 adult male Wistar rats divided into

8. Radionuclide therapy: current status and prospects for internal dosimetry in individualized therapeutic planning
The efficacy and toxicity of radionuclide therapy are believed to be directly related to the radiation doses received by target tissues; however, nuclear medicine therapy continues to be based primarily on the administration of empirical activities to patients and less frequently on the use of internal dosimetry for individual therapeutic planning. This revi

9. Crown Area as a Parameter for Biomass Estimation of Croton sonderianus Müll. Arg.
RESUMO As técnicas modernas para estimar biomassa arbórea geralmente usam dados de sensoriamento remoto e modelos alométricos para validação, que relacionam parâmetros não destrutivos com a biomassa da planta, normalmente empregando diâmetro basal ou diâmetro à altura do peito e altura da planta. No bioma Caatinga, muitas plantas apresentam múltip

10. Micropropagation, plantlets production estimation and ISSR marker-based genetic fidelity analysis of Guadua magna and G. angustifólia
RESUMO Os bambus Guadua magna e G. angustifolia têm sido propagados vegetativamente quase que exclusivamente por técnicas convencionais de propagação. Objetivou-se micropropagar, estimar a produção de mudas e analisar a fidelidade genética de G. magna e G. angustifolia por marcadores moleculares ISSR. Plantas matrizes de ambas as espécies foram culti

11. Bayesian sequential procedure to estimate the viability of seeds Coffea arabica L. in tetrazolium test
ABSTRACT: Tetrazolium tests use conventional sampling techniques in which a sample has a fixed size. These tests may be improved by sequential sampling, which does not work with fixed-size samples. When data obtained from an experiment are analyzed sequentially the analysis can be terminated when a particular decision has been made, and thus, there is no nee

12. Exponential smoothing for intermittent demand with demand basis updated more frequently than seasonality factors
Resumo Este estudo tem como objetivo apresentar uma técnica alternativa de suavização exponencial para estimar a demanda de itens com demanda intermitente e sazonal. A técnica usual consiste em agregar alguns períodos (meses agregados em trimestres, por exemplo) e calcular um fator de sazonalidade para o conjunto e, após fazer a estimativa para este,
