16. Effect of seed size and protein content and N application timing on seedling vigor and grain yield of barley.
The objective of this study was to evaluate the effect of seed size, protein content and N application timing on barley seedling vigor and grain yield. Two seed sizes, three protein levels and two genotypes (Hazen and Hazen semi-dwarf, SD, isotype pair) were used in a laboratory and in a field study. In a greenhouse study with Hazen only, N application timin

17. Decision criteria for optimizing postemergence Johnsongrass control in soybean crops in Argentina.
Field studies were established in Zavalla and Oliveros, Argentina, during four years in order to optimize Johnsongrass (Sorghum halepense (L.) Pers.) chemical control by means of the thermal calendar model in comparison with other criteria (weed height or days after sowing). The effect of three application dates of postemergence herbicides was determined by

18. SIMOO-RT : an object-oriented framework for the development of real-time industrial automation systems
This paper presents SIMOO-RT, an object-oriented framework designed to support the whole development cycle of real-time industrial automation systems. It is based on the concept of distributed active objects, which are autonomous execution entities that have their own thread of control, and that interact with each other by means of remote methods invocation.

19. Timing of nitrogen fertilizer application in no-tillage cotton in Brazil.
This study aimed at evaluating the agronomic efficiency of nitrogen (N) fertilizers blended with urease inhibitor, nitrification inhibitor, and a slow-release polymer applied at different times in a no-till cotton crop as well as the possibility of reducing the number of broadcast applications using conventional and alternative N sources. The experiment was

20. Resistance of soybean [Glycine max (L.) Merr.] to Fusarium solani f. sp. Glycines, causal agent of sudden death syndrome.
ABSTRACT: Sudden death syndrome (SDS) caused by the soilborne fungus Fusarium solani f. sp. glycine (FSG) is a major disease in soybean [Glycine max (L.) Merr.]. Slecetion for SDS resistance in the field is difficult because of the impact of the environment on disease development. The objective of my first study was to evaluate the effect of field inoculatio

21. Dinâmica folicular de vacas de corte tratadas com três protocolos de sincronização da ovulação =Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation / Ovarian follicular dynamics in beef cows treated with three protocols of synchronization of ovulation
Background: Artificial insemination is an established and viable technique to accelerate the genetic advancement and economic return of the cattle. However, compromises the efficiency of detection of estrus results in low insemination rates. To avoid these problems in beef herd, synchronization protocols have been developed that allow inseminate large number

22. Design of CAN-based distributed control systems with optimized configuration
A current trend in distributed control systems is the application of communication networktechnologies such as CAN - Controller Area Network. A recent utilization approach ofthese technologies is the networked control systems (NCS). The fundamental challenges inthe development of NCS are the analysis of the network delay effects and the prediction of the tim

23. Proposta de melhoria de tempo de resposta para o protocolo FTT-CAN : estudo de caso em aplicação automotiva
Embedded computing systems have become widely used in many areas. The greater part of those systems has time constraints and therefore they can be characterized as real time embedded systems. Nowadays, distributed computing has reached the embedded application, where some fieldbuses are already being used as communication platforms. Some important researches
