Development of a natural products database from the biodiversity of Brazil

We describe herein the design and development of an innovative tool called the NuBBE database (NuBBEDB), a new Web-based database, which incorporates several classes of secondary metabolites and derivatives from the biodiversity of Brazil. This natural product database incorporates botanical, chemical, pharmacological, and toxicological compound information. The NuBBEDB provides specialized information to the worldwide scientific community and can serve as a useful tool for studies on the multidisciplinary interfaces related to chemistry and biology, including virtual screening, dereplication, metabolomics, and medicinal chemistry. The NuBBEDB site is at http://nubbe.iq.unesp.br/nubbeDB.html. © 2013 The American Chemical Society and American Society of Pharmacognosy.

Modelagem do “tempo de execução” de obras civis: estudo de caso na Universidade Federal do Pará (UFPA)

O objetivo desta pesquisa é propor um modelo numérico prognóstico que trate a variável “tempo” de forma eficiente e eficaz, com a finalidade de atender às reais necessidades dos clientes-usuários e à sociedade em geral. Todavia, realizou-se um levantamento bibliográfico sobre gestão pública, no tocante a obras públicas, estatística e pesquisa operacional para sistema organizacional, visando à modelagem numérica. A pesquisa foi baseada em metodologias quantitativas, com ênfase na pesquisa operacional para o estudo das obras públicas executadas sob a gerência da Prefeitura (PCU) da Universidade Federal do Pará (UFPA). Para a elaboração da base de dados, foram coletados informações de obras, reformas e ampliações, executadas durante o período de 2006 a 2009, junto à Comissão Permanente de Licitação (CPL) e à Fundação de Amparo ao Desenvolvimento da Pesquisa (FADESP). Mediante as regressões lineares e, após as transformadas das funções, foram obtidos para o modelo prognóstico os parâmetros estatísticos: coeficiente de correlação (R), de 0,899; coeficiente de determinação (R²), de 0,808; coeficiente de determinação ajustado (R² ajustado), de 0,796; e erro padrão (Se), de 0,41. Esses parâmetros demonstram forte correlação linearizada entre as variáveis, indicando que 79,60% da variabilidade do tempo para executar uma obra pública é causada ou produzida pela variação, em conjunto, da área; do valor orçado; da capacidade técnica operacional da IFES; da capacidade operacional da empresa; da tipologia de serviço; e da estação do ano. Com os resultados obtidos, conclui-se que é possível aplicar e implementar o modelo prognóstico para execução de obras públicas, pois se obteve uma ferramenta potente em sua aplicação para as melhorias dos procedimentos administrativos, tanto na estrutura como no seu desempenho, cujo principal resultado é a previsão do tempo para execução do empreendimento público.

Interaction between GIS and hydrologic model: a preliminary approach using ArcHydro Framework Data Model

In different regions of Brazil, population growth and economic development can degrade water quality, compromising watershed health and human supply. Because of its ability to combine spatial and temporal data in the same environment and to create water resources management (WRM) models, the Geographical Information System (GIS) is a powerful tool for managing water resources, preventing floods and estimating water supply. This paper discusses the integration between GIS and hydrological models and presents a case study relating to the upper section of the Paraíba do Sul Basin (Sao Paulo State portion), situated in the Southeast of Brazil. The case study presented in this paper has a database suitable for the basin's dimensions, including digitized topographic maps at a 50,000 scale. From an ArcGIS®/ArcHydro Framework Data Model, a geometric network was created to produce different raster products. This first grid derived from the digital elevation model grid (DEM) is the flow direction map followed by flow accumulation, stream and catchment maps. The next steps in this research are to include the different multipurpose reservoirs situated along the Paraíba do Sul River and to incorporate rainfall time series data in ArcHydro to build a hydrologic data model within a GIS environment in order to produce a comprehensive spatial-temporal model.

Green Supply Chain Management: uma análise da produção científica recente (2001-2012)

The goal of this study was to analyze international scientific production in the area of constant-production green supply chain management from 2001 to 2012 using the Business Source Complete database (EBSCO Host). The database was checked for cooperation between authors and institutions, author entrants, production and continuity categories, regularity of publication and distribution of publications over time. Ninety articles were included in the sample, and the results showed a reduction in the number of publishing authors, concentrated in one-timers category with 68.90%. The highest yield for a single author was 10 articles, and the most prolific periodical was the Journal of Cleaner Production, with 12 articles published on the subject. Clark University (USA) stood out in terms of output, with 12 affiliated authors. It was concluded that the subject had experienced a significant rise in published literature over that time period.

A tool for controlling accelerometers. Secondary calibration data

Vibration monitoring requires acceleration transducers capable of providing data with high precision. Accelerometers are the most frequently used vibration transducers. Their calibration plays an important role in measuring vibrations and is a key component in ensuring the integrity of the vibration measurement. For managing secondary calibration data of accelerometers, a database computer system was implemented. The implementation of this software has been an important step forward in providing a wide range of analysis and display tools. This paper reviews the main concepts involving accelerometer secondary calibration and describes the tool developed and the methods used in its development. (C) 2013 Academie des sciences.

Rapid Assessment of Seed Removal and Frugivore Activity as a Tool for Monitoring the Health Status of Tropical Forests

Ecological processes in tropical forests are being affected at unprecedented rates by human activities. Yet, the continuity of ecological functions like seed dispersal is crucial for forest regeneration. It thus becomes increasingly urgent to be able to rapidly assess the health status of these processes in order to take appropriate management measures. We tested a method to rapidly evaluate seed removal rates on two animal-dispersed tree species, Virola kwatae and V.michelii (Myristicaceae), at three sites in French Guiana with increasing levels of anthropogenic disturbance. We counted fallen fruits, fruit valves, and seeds of each focal fruiting tree in a single 1m2 quadrat, and calculated two indices: the proportion of seeds removed and the proportion of fruits opened by mammals. They both provide an indirect and rapid assessment of frugivore activity. Our results showed a significant decrease in the proportion of removed seeds (16%) and fruits opened (19%) at the most impacted site in comparison with the other two sites (79% for seeds, 60% and 35% for fruits). This testifies to an increased impoverishment of the primate and toucan communities at the disturbed sites. This standardized protocol provides fast information about the health status of the community of seed dispersers and predators and of their seed removal services. It is time- and cost-effective and is not species-specific, allowing comparisons among sites or over time. We suggest using it with the pantropical Myristicaceae and any other capsule-producing family to rapidly assess the health status of seed removal processes across the tropics.

Modelagem do transporte de sedimentos na alta Bacia do Córrego Cachoeirinha (Rio Claro, SP) através do software Soil and Water Assessment Tool (SWAT)

This study aimed to simulate and evaluate the sediment transport in Upper Basin Stream Cachoeirinha in Rio Claro, SP, and compare the results with previous studies performed in the same basin. The modeling software used in this study was Soil and Water Assessment Tool (SWAT), which is a very comprehensive tool that discusses many physical processes. In this work, the hydrosedimentological processes were treated, aiming to understand the sediment production and transport. The Basin Stream Cachoeirinha has an area with predominantly agricultural use, especially sugar cane. The database for inclusion in software was constructed from the following elements: climatic, topographical, soil type and use and land cover of the area, also including the parameters of Modified Universal Soil Loss Equation (MUSLE). The analysis was conducted for a period of 16 years (1994-2010), which is the range of data available from CEAPLA. The results were analyzed in terms of annual runoff and sediment yield. The average sediment delivery in the simulation was 0.94 t/ha/year, while the maximum annual contribution was 7.28 t/ha/year
