Ecophysiology modeling by artificial neural networks for different spacings in eucalypt

Growth and production models are widely used to predict yields and support forestry decisions. Artificial Neural Networks (ANN) are computational models that simulate the brain and nervous system human functions, with a memory capable of establishing mathematical relationships between independent variables to estimate the dependent variables. This work aimed to evaluate the efficiency of eucalypt biomass modeling under different spacings using Multilayer Perceptron networks, trained through the backpropagation algorithm. The experiment was installed in randomized block, and the effect of five planting spacings was studied in three blocks: T1 – 3.0 x 0.5 m; T2 – 3.0 x 1.0 m; T3 – 3.0 x 1.5 m; T4 – 3.0 x 2.0 m e T5 – 3.0 x 3.0 m. A continuous forest inventory was carried out at the ages of 48, 61, 73, 85 and 101 months. The leaf area, leaf perimeter and specific leaf area were measured at 101 months in one sample tree per experimental unit. Two thousand ANN were trained, using all inventoried trees, to estimate the eco-physiological attributes and the prognosis of the wood biomass. The artificial neural networks modeling was adequate to estimate eucalypt wood biomass, according to age and under different spacings, using the diameter-at-breast-height and leaf perimeter as predictor variables.Growth and production models are widely used to predict yields and support forestry decisions.

Climatic suitability for Eucalyptus cloeziana cultivation in four Brazilian states

The objective of this work was to identify zones with climatic potential for Eucalyptus cloeziana cultivation in four Brazilian states (Bahia – BA, Mato Grosso do Sul – MS, Minas Gerais – MG e São Paulo – SP). 490 records of this species in Australia were obtained. Current prediction of the distribution of habitat suitability was based on climatic conditions recorded between 1960 and 1990. For the future projections of 2050, four scenarios were used: RCP 2.6 W/m2, RCP 4.5 W/m2, RCP 6.0 W/m2 and RCP 8.5 W/m2. MaxEnt was used in modeling, and only climatic information was used as predictor variables. The modeling was robust and presented high values of AUC (> 0.95). Annual precipitation and isothermal were the variables that contributed the most for the quality of the models. It was concluded that the Brazilian mesoregions of Itapetininga (SP), Litoral Sul Paulista (SP) and Zona da Mata (MG) presented the most climatically suitable sites for E. cloeziana cultivation. Climatic changes may restrict the distribution of suitable zones for E. cloeziana cultivation. The negative effect of global warming was more prominent in MG

CROWN MORPHOMETRIC INDEXES OF EUCALYPT ESTIMATED BY LOGISTIC REGRESSION AND SUPPORT VECTOR MACHINES

The proper choice of the modeling method for morphometric tree crown estimates is important to optimize measurement and support silvicultural decision-making. This study aims to evaluate the efficiency of interdimensional morphometric relationships modeling of eucalypt crown under different spacings using logistic regression and Support Vector Machines (SVM). The experiment was set up with four spacings (T1: 3.0 × 0.5 m; T2: 3.0 × 1.0 m; T3: 3.0 × 1.5 m and T4: 3.0 × 2.0 m). A continuous forest inventory was carried out at the ages of 24, 37, 48, 59 and 72 months. Two modeling methods, one using nonlinear regression (logistic model) and the other using SVM, were tested. The range, salience and vital space indexes decreased with increasing tree stem dimensions, tending to stabilization. The logistic model was satisfactorily adapted to the problems, more specifically in prediction of the first two indexes. SVM modeling using radial base Kernel function can be used with good precision for crown morphometric indexes estimation of eucalypt, simultaneously, for different planting spacings

Modelos hipsométricos para mudas de Aspidosperma polyneuron Müll. Arg. (Apocynaceae) e Cedrela fissilis Vell. (Meliaceae) / Hypsometric models for seedlings of Aspidosperma polyneuron Mull. Arg. (Apocynaceae) and Cedrela fissilis Vell. (Meliaceae)

A relação hipsométrica pode ser definida como a regressão da altura sobre o diâmetro e sua aplicação permite reduzir o tempo gasto com levantamentos biométricos, aumentando o rendimento da amostragem. O objetivo foi testar e selecionar os melhores modelos hipsométricos tradicionais e lineares para estimar a altura de mudas de Aspidosperma polyneuron e de Cedrela fissilis. Os dados foram obtidos de mudas produzidas via propagação seminal e, posteriormente, divididos entre grupos de parametrização e validação. O desempenho de 12 modelos, que descrevem as alturas em função dos diâmetros na região do coleto, foram testados. O critério de seleção das equações mais precisas foi baseado em um conjunto de medidas de precisão e de estabilidade. O Syx(%) foi diferente entre os modelos testados; variando mais para A. polyneuron (de 16,20% a 19,78%) e menos para C. fissilis (de 17,41% a 17,95%). O modelo hiperbólico “” e o exponencial “” foram aqueles de melhor performance quando ajustados para estimar a altura das mudas de A. polyneuron e de fissilis, respectivamente. Esses modelos foram validados com dados independentes, proporcionando estimativas confiáveis

An Electroanalytical Solution for the Determination of Pb2+ in Progressive Hair Dyes Using the Cork–Graphite Sensor

open7Lead is one of the most toxic metals for living organisms: once absorbed by soft tissues, it is capable of triggering various pathologies, subsequently bioaccumulating in the bones. In consideration of this, its detection and quantification in products for human consumption and use is of great interest, especially if the procedure can be carried out in an easy, reproducible and economical way. This work presents the results of the electroanalytical determination of lead in three different commercial products used as progressive hair dyes. Analyses were performed by cyclic voltammetry (CV) and differential pulse stripping voltammetry (DPSV) using a composite cork–graphite sensor in 0.5M H2SO4 solution or 0.1M acetate buffer (pH 4.5), in the presence and absence of hair dye samples. The H2SO4 solution gave better results in terms of analyte sensitivity than the acetate buffer electrolyte. In both cases, well-defined signals for lead were obtained by DPSV analyses, enabling the calibration curve and figures of merit to be determined. The limits of detection (LOD) were found to be approximately 1.06 µM and 1.26 µM in H2SO4 and acetate buffer, respectively. The DPSV standard addition method was successfully applied to quantify the lead in hair dye samples, yielding values below 0.45% in Pb. All three analyzed samples were shown to comply with the limit set by the Brazilian Health Regulatory Agency, i.e., 0.6% lead in this type of product. The comparison of the electroanalytical results with those obtained by the reference method, based on the use of inductively coupled plasma optical emission spectrometry (ICP–OES), confirmed that the electroanalytical detection approach is potentially applicable as a strategy for quality control.openBarros, Thalita Medeiros; Medeiros de Araújo, Danyelle Medeiros de; Lemos de Melo, Alana Tamires Lemos de; Martínez-Huitle, Carlos Alberto; Vocciante, Marco; Ferro, Sergio; Vieira dos Santos, Elisama Vieira dosBarros, Thalita Medeiros; Medeiros de Araújo, Danyelle Medeiros de; Lemos de Melo, Alana Tamires Lemos de; Martínez-Huitle, Carlos Alberto; Vocciante, Marco; Ferro, Sergio; Vieira dos Santos, Elisama Vieira do

Crown projection area of Licania tomentosa (Benth.) Fritsch (Chrysobalanaceae), estimated by linear regression / Área de projeção da copa de Licania tomentosa (Benth.) Fritsch (Chrysobalanaceae), estimada por regressão linear

Knowledge of the Crown Projection Area (CPA) allows to make inferences about the shading and to know space occupied by a tree. However, crown measurements are more time-consuming and laborious when compared to those of Circumference Breast Height (CBH). Thus, this work aimed to evaluate regression models and present the most suitable to CPA estimate of Licania tomentosa, in an urban area of São João Evangelista municipality, Brazil. Fifty trees distributed over 7 public roads were sampled. CBH and Crown Diameter (CD, m) were measured for later calculation of its projection area (CPA, m2). Four regression models were tested in order to estimate CPA as a function of CBH alone. The equation derived from of the model “” showed a homoscedastic distribution of the percentage residues, with closer deviations around the abscissa axis. It is concluded that the equation obtained with the adjustment of the simple linear model was the most efficient to estimate of the crown projection area of L. tomentosa. This projection area increased as the stem of the trees thickened

LEGISLAÇÃO DE COSMETOVIGILÂNCIA NO BRASIL E PERFIL DAS CONSUMIDORAS DE COSMÉTICOS DO CENTRO UNIVERSITÁRIO DE ANÁPOLIS

A produção de cosméticos no Brasil vem apresentando crescimento bem acima da média geral de produtos. O aumento no consumo fez crescer o aumento nas reclamações e reações adversas relacionadas a estes produtos. O objetivo da pesquisa é relatar a evolução das normas brasileiras referentes à segurança e eficácia de produtos cosméticos e descrever o perfil de consumo e uso de cosméticos por estudantes do Centro Universitário de Anápolis (CUA). Buscou-se normas e leis sobre cosméticos nos sites Bireme, CAPES e ANVISA. As palavras chave pesquisadas foram: cosmetovigilância, reações adversas, consméticos, SAC. De 93 artigos selecionados utilizou-se 20, excluindo-se aqueles cujo tema não se relacionava com os descritores. Aplicou-se um questionário a 200 consumidoras de cosméticos do CUA. Os resultados demostram que 60% das consumidoras relataram reações adversas. Os locais de ocorrência das reações são a face (42%), couro cabeludo (14%), a pele do corpo (21% ) e olhos (18%). As reações adversas mais relatadas foram: vermelhidão (54%), coceira (49%), ardência/queimação (39%) e descamação (23%). Os principais produtos causadores das reações foram os cosméticos para área dos olhos, filtros solares e cremes depilatórios. Observou-se que apenas 30% das entrevistadas possuem o hábito de conferir a existência do nº de telefone do SAC nos rótulos, e 78% das consumidoras sempre verificam o prazo de validade antes de utilizar o produto. Apesar da grande porcentagem de efeitos adversos, apenas 4,0% das entrevistadas entraram em contato com o SAC das empresas. Destas, 62% não obtiveram solução para seu problema, 17% tiveram solução parcial e 22% tiveram solução total para o caso. Os resultados demonstram que é preciso haver melhorias e mudanças nos SAC’s, para que sejam mais eficientes
