Core Ideas The optimum leaf area index (LAI) at beginning bloom to reach the yield potential is between 3.6 (indeterminate stem termination) and 4.5 (determinate termination). LAI maximum 6.0 6.5 for indeterminate determined cultivars. high should be adjusted according maturity group, termination sowing date. increase in was observed with of experiments farms a technological level (soybean more than Mg ha −1 ). interactive influence climate management factors on soybean has not been...

In recent years, the consumption of electricity has increased considerably in industrial, commercial and residential sectors. This prompted a branch research which attempts to overcome this problem by applying different information communication technologies, turning houses buildings into smart environments. paper, we propose design an energy saving technique based on relationship between user's activities electrical appliances home The proposed method utilizes machine learning techniques...
This work presents the design of a variable-damping prosthesis for above-knee amputees. The proposed low cost system is self-contained and based on four-bar polycentric mechanism, in which magnetorheological linear damper integrated to enable control. paper also describes control strategy Finite State Machine, will modulate damping level according actual state gait cycle. Preliminary tests an amputee subject provided satisfactory performance while operating passive mode, i.e., simulating...
The inappropriate use of features intended to improve usability and interactivity web applications has resulted in the emergence various threats, including Cross-Site Scripting(XSS) attacks. In this work, we developed ETSS Detector, a generic modular vulnerability scanner that automatically analyzes find XSS vulnerabilities. Detector is able identify analyze all data entry points application generate specific code injection tests for each one. results shows correct filling input fields with...
Potato (Solanum tuberosum ssp. Tuberosum) crop is particularly susceptible to water deficit because of its small and shallow root system. The fraction transpirable soil (FTSW) approach has been widely used in the evaluation plant responses different crops. FTSW 34 threshold (when stomatal closure starts) a trait particular interest it an indicator tolerance deficit. for decline transpiration leaf growth was evaluated drying identify potato clones tolerant Two greenhouse experiments were...
Abstract: The objective of this work was to evaluate soybean cultivation in a hydromorphic or nonhydromorphic soil, with without supplemental irrigation. Field experiments were carried out the TECIRGA 6070RR and A 6411RG cultivars highlands (nonhydromorphic soils) lowlands (hydromorphic soils), which are traditionally cultivated irrigated rice. following parameters determined both cultivars: leaf area index, developmental stages, dry matter partition, gas exchange. Low water stresses,...
ABSTRACT There was a change in the genetics of soybeans grown southern Brazil from 2000s, which requires investment basic and detailed studies about growth development. The purpose this paper to characterize overlap period vegetative reproductive phases, height emission nodes after beginning flowering determinate indeterminate cultivars different sowing dates soybean regions Rio Grande do Sul. Field experiments were conducted during growing seasons 2012/2013 2013/2014, Santa Maria, Itaqui,...
Percutaneous surgical procedures depend on the precise positioning of needle tip for effectiveness. Although, robustly locating still represents a challenge, specially when flexible needles are used. An imaging technique widely used this task is 2D ultrasound, however low signal/noise ratio makes it difficult to apply conventional image processing techniques. In work, we propose an alternative method detecting in ultrasound and tracking during complete insertion. The proposed combines...
RESUMO A irrigação suplementar e a cobertura do solo ("mulching") são práticas de manejo comumente usadas na agricultura. O objetivo deste trabalho foi quantificar temperatura desnudo com sem irrigação, sob diferentes coberturas solo. Um ensaio campo conduzido em Santa Maria-RS (29o 43' S latitude, 53º 42' W longitude 95 m altitude), seis áreas: "mulching" plástico transparente (espessura 100 µm), opaco preto 110 branco 150 µm) vegetal palha dose 5 t ha-1. medida 0,05 profundidade,...
In percutaneous surgical procedures, the precise positioning of needle tip is paramount relevance for good performance. Nevertheless, locate a inserted in patient still represent challenge. An imaging technique widely used this task ultrasound imaging, however low signal/noise ratio often make virtually impossible use simple image processing techniques. work, we propose an alternative way to detect needles images using Multi-Layer Perceptron neural networks. The results show detection most...
