The recently emerged Covid-19 virus has caused more than 65,872,391 infections and 1,523, 656 deaths up to December 8, 2020
worldwide. The disease continues to spread in all countries. The use of mathematical models in public health plays an important role in
many aspects, such as rapid visualization of epidemiological information, monitoring, fore...
RESUMO: A deficiência hídrica do solo por ocasião do plantio e associação de patógenos com sementes podem ocasionar a diminuição da germinação e vigor de um lote de sementes, levando à redução do estande e introdução de doenças no campo. Nesse trabalho utilizou-se sementes de algodoeiro cultivar Deltapine Acala 90 (suscetível a ramulose) e linhagem...
RESUMO -O objetivo deste trabalho foi de encontrar a relação entre a produtividade de sementes de soja e seus respectivos índices de vegetação e seu comportamento espectral. O estudo foi realizado no município de Alto Garças -Mato Grosso. De posse dos dados de produtividade georreferenciados, foram utilizadas imagens multiespectrais do satélite Lan...
The objective of this study was to develop a methodology to characterize the intensity of soybean crop production, based on the association of data of production obtained in municipal level and image of orbital remote sensing, as well as to generate a model of soybean production forecasting in function of cultivated area in Mato Grosso state. The d...
Coffee production has historical importance in the development of Brazil. The characteristics of this grain crop are influenced by soil properties regarding the availability of nutrients needed for appropriate metabolic cycle of the plant. Among these nutrients, phosphorus has important role in the development of coffee because their deficiency aff...
The spatial analysis of micronutrient distribution of manganese in the soil of coffee crops is important for increasing crop productivity and lower costs. The use of geostatistical tools are fundamental to assess the distribution of parameters that affect the development of crops such as coffee. A deficiency of manganese in the coffee plantations c...
Geostatistics was used to detect the existence of spatial variability of variables constituting an important tool in the analysis and detailed description of the variability of soil chemical attributes. In recent years, the geoestatistic has been applied in many precision agriculture works. This study aims to analyze the spatial variability of the...
The Pantanal is one of the richest biomes of Brazil in relation to its beauty and diversity of fauna and flora. Pantanal has many landscapes like the bays. In the Pantanal of Mato Grosso, one of the most prominent bays is the one called Chacororé. This bay receives sediments from the highlands of their surroundings and over these sediments can harm...
The yield mapping is essential in precision agriculture, as it helps to define management zones. With geostatistical calculations is possible to map productivity with reliable results. The objective was to evaluate the use of precision agriculture technology to monitor the harvest of soybean in the field, through sensors embedded in harvester machi...
The Pantanal is one of the largest sedimentary plains of the globe and is distinguished by having distinct seasons, times of drought and flood. Considering that, by means of remote sensing is possible to facilitate and improve the analysis of information such as water, soil and vegetation, aimed to achieve the spatial and temporal assessment of the...
This study aims to monitor the Xingu Indigenous Park for Remote Sensing, comparing satellite images provided by the sensor AWiFS by satellite IRS-P6, at June 11, 2010. Post perform radiometric and geometric correction of images, it was determined the indices (1) soil adjusted vegetation index, (2) leaf area index (LAI) (3), fraction of absorbed pho...

... Studies have reported that COVID-19 has the potential to travel large distances in a tumultuous atmosphere and infect neighboring countries. The rapidity at which this infection is spreading among populations is extraordinary (1)(2)(3)(4)(5). The COVID-19 pandemic is a major health crisis affecting several countries, and such widespread outbreaks are associated with adverse mental health consequences during the pandemic situation (6). ...

... O CV não tem sido considerado como bom indicador da variabilidade espacial dos atributos do solo, quando utilizado individualmente, pois em alguns casos pode mascarar a real interpretação da heterogeneidade espacial sobre os valores médios. Nesse caso, é recomendada a utilização da análise geoestatística (Sampaio et al., 2011). ...
... From the processing and geo-referencing for the horizontal Datum SIRGAS, 2000, Zone 23S and UTM projec� on, the images were added to the GIS, by using the so� ware ArcGIS 10.3.1. The colored composi� on of RGB bands and false color of the orbital images from Landsat satellites was performed with the objec� ve to emphasize the diff eren� a-� on between water bodies and land (Meneses and Almeida, 2012; Rosa et al., 2011). ...
