Influence of the sample area in the variability of losses in the mechanical harvesting of soybeans
(2014-01-01)
The mechanical harvesting is an important stage in the production process of soybeans and, in this process; the loss of a significant number of grains is common. Despite the existence of mechanisms to monitor these losses, ...
Geotechnology applied to estimate soil loss by water erosion
(2015-01-01)
Water erosion is a major environmental problem that may compromise agricultural areas and the volume of water in a watershed. This paper presents the estimated soil loss in a watershed using Equation Revised Universal Soil ...

Tolerância de perdas de solo na bacia do rio Itiquira, Mato Grosso, Brasil
(2004-06-01)
The geographic area of the present study corresponds to the basin of the Itiquira river high course (Figure 1), in the portion that extends from the tributaries of its source, in the east of the plateau Correntes/Itiquira, ...
The Dirac-delta functions for signal path-loss modeling at mid-sized urban areas
(Institute of Electrical and Electronics Engineers Inc., 2014-09)
A study of the Dirac-Delta functions with polynomial argument for modeling the signal path-loss in mid-sized urban areas is presented. From the fundamental "spike" property of the Dirac-Delta functions, or simply Delta, ...
Critical yield components and key loss factors of tropical cucumber crops

Assessing how habitat loss restricts the geographic range of Neotropical anurans
(Springer, 2016-11-01)
Habitat loss and fragmentation exert unquestionable negative effects in a wide range of taxa on both regional and local scales. However, there is a debate over whether habitat change impacts geographic species distribution. ...
STATISTICAL PROCESS CONTROL APPLIED TO MONITOR LOSSES IN THE MECHANIZED SUGARCANE HARVESTING
(Soc Brasil Engenharia Agricola, 2020-07-01)
The mechanized sugarcane harvesting process is considered one of the major economic bottlenecks, with low operational efficiency and, mainly, high losses of stalks left in the field. In order to minimize these problems and ...
Colheita mecanizada e perdas quantitativas de sementes de crotalária
(2010-03-01)
In mechanized harvesting of seeds can occur losses, which reduce productivity, decrease the profitability and can do serious damage to the producer. The objective of this work was to evaluate the quantitative seed losses ...
Evaluating and classifying contaminated areas based on loss functions using annealing simulations
(Elsevier B.V., 2009-06-01)
This paper presents a methodology based on geostatistical theory for quantifying the risks associated with heavy-metal contamination in the harbor area of Santana, Amapa State, Northern Brazil. In this area there were ...
