This app employs Single Linear Correlation technics for univariate analysis and Principal Component Analysis (PCA) for multivariate exploratory analysis, including Partial Least Square Regression (PLS). The image data are acquired using the device main camera and photo album, both converted in RGB histograms. In addition, apart color channels of RGB, HSV, HSL and HSI systems are used during the univariate and multivariate processes. It is possible to send by e-mail the image data, analysis data and charts. In order to validate the obtained results, the same sets of data were tested using Microsoft Excel© and ChemoStat©. The results in both applications coincided in various combinations. This app calculates and plot: eigenvalues, eigenvectors, scores, loadings using Singular Value Decomposition in Multivariate Analysis. This app calculates and plot: slope (span), intercept (off-set) and regression (Pearson product-moment correlation coefficient) in Univariate Calibration Analysis. http://dx.doi.org/10.5935/0103-5053.20160182

Below is a message from the event organizers: Dear Colleagues and Friends, We are thrilled to welcome you to the 54rd Annual Meeting of the Brazilian Society of Biochemistry and Molecular Biology (SBBq), at the Majestic Hotel Convention Center in Águas de Lindóia, SP, May 17 to 20, 2025. SBBq´s annual meeting is one of Brazil's most esteemed scientific events, having been held continuously for over four decades. It is a vital forum for scientific exchange, promoting the advancement of knowledge in Biochemistry, Molecular Biology, and related fields. It also fosters discussions on scientific education and training, as well as consensus positions in the field, contributing towards public policies. This year, the organizing committee has created an engaging interdisciplinary program that features 8 plenary lectures and 18 symposia led by world-class scientists. These sessions will highlight the latest advancements and current challenges across various research topics in Biochemistry and Molecular Biology. We are also pleased to include policy thinkers who will assess the landscape of science and technology in our country. We eagerly anticipate your presence in Águas de Lindóia! Alicia J. Kowaltowski SBBq President
