(Escola De MinasOuro PretoBrasil, 2012)
Computer-Assisted Approach to Structural Elucidation of Lignans
(TAYLOR & FRANCIS INC, 2008)
This paper reports an expert system (SISTEMAT) developed for structural determination of diverse chemical classes of natural products, including lignans, based mainly on 13C NMR and 1H NMR data of these compounds. The ...
Cystic spermatogenesis in three species of the prolixus complex (Hemiptera: Triatominae)
(Taylor &francis Ltd, 2015-04-03)
The reproductive biology of triatomines and, more specifically, the general aspects of spermatogenesis and spermiogenesis are well known. However, reported structural analyses of the testicles are restricted to the genus ...
Synthesis, leishmanicidal activity, structural descriptors and structure-activity relationship of quinoline derivatives
(Future Sci Ltd, 2018-09-01)
Aim: Considering the epidemiology of leishmaniasis, the emergence of resistant parasites to the approved drugs, and severe clinical manifestations, the development of novel leishmanicidal molecules has become of considerable ...
The correlation between electronic structure and antimalarial activity of tetrahydropyridines
(Soc Brasileira Quimica, 2015-02-01)
In this study, correlations between electronic structure and the antimalarial activities reported for a group of 21 tetrahydropyridines were evaluated by multivariate methods. Simple and multiple linear regressions, principal ...
Analysing green supply chain management practices in Brazil's electrical/electronics industry using interpretive structural modelling
Industries need to adopt the environmental management concepts in the traditional supply chain management. The green supply chain management (GSCM) is an established concept to ensure environment-friendly activities in ...
Initial description of the phylogeography, population structure and genetic diversity of Atlantic spotted dolphins from Brazil and the Caribbean, inferred from analyses of mitochondrial and nuclear DNA
We provide initial information regarding the population structure and genetic diversity of Stenella frontalis from the Caribbean and southeastern Brazil from analyses of mitochondrial control region sequences and sequences ...
Evaluating the existence of structural change in the brazilian term structure of interest: evidence based on cointegration models with structural break
This paper investigates whether there is evidence of structural change in the Brazilian term structure of interest rates. Multivariate cointegration techniques are used to verify this evidence. Two econometrics models are ...
