1. COMPARAÇÃO ENTRE MÉTODOS PARA DETERMINAÇÃO DE CARGAS ATÔMICAS EM SISTEMAS MOLECULARES: A MOLÉCULA N-{N-(PTERINA-7-IL)CARBONILGLICIL}-L-TIROSINA (NNPT)
Selecting a method to compute partial atomic charges is not trivial because different methods usually provide different charge values and there is no consensus on the most useful approach. In this work, Mulliken, MBS, Chelp, Chelpg, MK, Hirshfeld, NPA, DMA and AIM methods were selected to compute atomic charges and electric dipole moment vector of N-{N-(Pter

2. Growth analysis of potato genotypes
ABSTRACT Analyzes of plant growth throughout the crop vegetative cycle are important to know the dynamics of the plant development. Thus the objective of this work was to study the development of potato genotypes throughout the crop cycle, in three environments. Experiments were conducted in Canoinhas-SC, Pelotas-RS, and Brasília-DF, Brazil, in the 2018 cro

3. Ornamental fishing in the region of Barcelos, Amazonas: socioeconomic description and scenario of activity in the view of “piabeiros”
Resumo A bacia do rio Negro é considerada a maior área de extrativismo de peixes ornamentais do Brasil. Esta área possui importância fundamental para as populações da Amazônia. O presente estudo objetivou descrever o perfil socioeconômico de pescadores conhecidos como “piabeiros” no município de Barcelos, bem como a pesca ornamental, área de pe

4. Mimosa scabrella Benth. as Facilitator of Forest Successional Advance in the South of Brazil
ABSTRACT Pioneer species have the potential to colonize disturbed environments, contributing to the establishment of other species and driving the dynamics and advancement of the structure of forest communities. The aim of this study was to assess the evolution of floristic-structural composition in the regenerating stratum of communities formed in the Mimos

5. System dynamics for social good
Abstract Paper aims This paper portrays three examples of system dynamics modes applied to social good. Originality System dynamics has a strong tradition of applied research addressing complex social issues ranging from world and urban dynamics to the spread of infectious diseases. System dynamics can provide insight and inform long-term policy in complex

6. Thresholds Are Everywhere: A Systems Approach to Public Policy
Abstract The analysis of public policies often fails to account for effects beyond mere cost-benefit analysis. Incorporating elements from the literature on system dynamics, complexity and legitimacy, the present paper develops a framework to understand long-term effects and important constraints for public policies. We call it the thresholds framework, cons

7. Orchid bees (Hymenoptera, Apidae, Euglossini) are seasonal in Seasonal Semideciduous Forest fragments, southern Brazil
Abstract Seasonal fluctuations in the abundance of orchid bees have already been reported. The variations in population dynamics may be expected to occur in more predictable and pronounced manners in environments with a clear distinction between rainy and dry seasons, where climatic variables are regarded to be good predictors of populational patterns. The m

8. Relevant parameters for characterizing mountain rivers: a review
RESUMO Rios montanhosos estão presentes em uma grande porção dos territórios do planeta, especialmente nas regiões de cabeceiras, e vêm sendo utilizados para diversos fins, tais como recreação e atividades desportivas, mananciais de água e geração de energia hidrelétrica. Entretanto, suas características hidrogeomorfológicas ainda não são pl

9. Competitive Capacity and Rhizosphere Mineralization of Organic Matter During Weed-Soil Microbiota Interactions
RESUMO: A competição entre plantas daninhas e culturas é um dos principais fatores responsáveis por perdas de produtividade nos campos agrícolas. Esta revisão teve como objetivo apresentar e discutir como a interação entre plantas daninhas e microrganismos pode afetar a capacidade competitiva de plantas daninhas, bem como as propriedades físico-quí

10. Genesis and Classification of Nitisols from Volcano-Sedimentary Lithology in Northeastern Brazil
ABSTRACT On the southern coast of Pernambuco State (PE), Brazil, lithotypes of the Cabo Basin (volcanic and sedimentary rocks), in association with the relief, allow the determination of the dynamics of the formation of Nitossolos Háplicos (Nitisols), including those with high levels of exchangeable aluminum. The objective of this study was to evaluate the

11. Investigar la “otredad” en hospitales: desafíos en un estudio cualitativo sobre terapias no-convencionales en espacios de salud oficiales (Argentina)
Este artigo discute os problemas encontrados em um estudo qualitativo de orientação etnográfica que explora o fenômeno das medicinas não-convencionais em ambientes hospitalares, em Buenos Aires (Argentina). Em diálogo com a literatura acadêmica que explora os desafios metodológicos, éticos e políticos da etnografia no campo da saúde, o artigo é d

12. Lessons and perspectives for applications of stochastic models in biological and cancer research
The effects of randomness, an unavoidable feature of intracellular environments, are observed at higher hierarchical levels of living matter organization, such as cells, tissues, and organisms. Additionally, the many compounds interacting as a well-orchestrated network of reactions increase the difficulties of assessing these systems using only experiments.
