1. Selectivity and residual weed control of pre-emergent herbicides in soybean crop
ABSTRACT The use of pre-emergent herbicides is important for the current agricultural production systems that present weeds resistant to herbicides. Considering the complexity of using these products, the objective of this work was to evaluate their selectivity and residual weed control in soybean crops and their effect on the weeds Amaranthus hybridus, Bide

2. Breaking the misconception of a dry and lifeless semiarid region: the diversity and distribution of aquatic flora in wetlands of the Brazilian Northeast
ABSTRACT The semiarid region of northeastern Brazil possesses a set of wetlands characterized by hydrographic basins with deficient drainage networks, a few large and permanent lotic systems and several permanent and temporary lagoons. Aquatic plants are widely distributed in these wetlands and the present study aims to determine if those of Ceará state hav

3. Control of Italian ryegrass and Alexandergrass in corn using different corn sowing date, pre- and post-emergent herbicides
ABSTRACT Glyphosate-resistant (GR) Italian ryegrass (LOLMU) and Alexandergrass (URPLA) are troublesome weeds in corn cropping systems in Southern Brazil. The emergence pattern of those weeds is not uniform and may change according to the season’s environmental characteristics. Also, herbicide resistance has been diminishing the success of the weed control

4. Dolops carvalhoi as a vector of Epistylis sp. between cultivated and wild specimens of Oreochromis niloticus in Brazil
Resumo Epistilíase tem sido caracterizada como uma doença emergente de grande impacto nas pisciculturas, especialmente em sistemas de produção de Oreochromis niloticus. Embora seja importante epidemiologicamente, informações sobre a dispersão desses parasitas e seus vetores mecânicos são escassos. O presente estudo relata a coocorrência de Epistyli

5. Integrating the pastoral component in agricultural systems
ABSTRACT This paper aims to discuss the impact of the introduction of pastures and grazing animals in agricultural systems. For the purposes of this manuscript, we focus on within-farm integrated crop-livestock systems (ICLS), typical of Southern Brazil. These ICLS are designed to create and enhance the synergisms and emergent properties have arisen from agr

6. Impacts of Interactive and Diagnostic Control System Use on the Innovation Process
Abstract This research explores the innovation process in organizations based on the Management Control System (MCS). We examined the link between the diagnostic and interactive uses of management control systems and their association with the intensity of the innovation process. Motivations for the research are: (a) enhance the potentiality of the model by

7. A proposal towards resilient complex networks through evaluation and adaptation mechanisms
Attacks and failures tolerance of complex networks is related to the concept of vulnerability in different contexts, from biology and sociology to computer science and physics. Studies have revealed that the topologies of these networks are inherently vulnerable to failures of central elements. Complex adaptive systems, emergent in nature, are considered mor

8. Modelo de múltiplas escalas para a dinâmica de crescimento de estruturas biológicas ramificadas / Multiscale model for the dynamics of growth of biological branching structures
The characterization of fractals and the search for general rules and mechanisms for description of non-linear phenomena brought the attention of the scientific community to the interdisciplinary area of complex systems. Complex phenomena can be found in almost every branch of natural science. One example is the simulation using cellular automata of self-org

9. Complejidad: una introducción
Complexity appears in the twentieth century as a way to understand many phenomena that are perceived as chaotic and complex from classical thought, which still persist in our way of explaining the world. Its purpose is to study the complex and adaptive systems that are sensitive to inicial conditions. Some of the characteristics of complex thought are system

10. Análise do gerenciamento ambiental nos hospitais de Caxias do Sul - RS
The activities of the elderly health assistance institutions generate tons of hospital residues daily. The efficiency of the health sector is questioned, concerning the management of hospital residues, as an emergent subject in the environmental problematic. Currently we count on management practices and the support of the current laws that are designed with

11. Effect of organic tomato ( Lycopersicon esculentum ) extract on the genotoxicity of doxorubicin in the Drosophila wing spot test
The consumption of organic tomatoes (ORTs) reduces the risk of harmful effects to humans and the environment caused by exposure to toxic agrochemicals. In this study, we used the somatic mutation and recombination test (SMART) of wing spots in Drosophila melanogaster to evaluate the genotoxicity of ORT and the effect of cotreatment with ORT on the genotox

12. Learning about brain physiology and complexity from the study of the epilepsies
The brain is a complex system, which produces emergent properties such as those associated with activity-dependent plasticity in processes of learning and memory. Therefore, understanding the integrated structures and functions of the brain is well beyond the scope of either superficial or extremely reductionistic approaches. Although a combination of zoom-i
