13. Parents choice and genetic divergence between cambuci fruit tree accessions
Abstract Fifty-eight cambuci fruit accessions were collected and propagated by seeds. Forty fruits of each accession were collected and evaluated for longitudinal and transverse diameter, fruit weight, number of seeds, seeds weight, total soluble solids, % citric acid, ratio, pH, firmness, vitamin C, and color. The phenotypic correlation between the characte

14. The HPLC Fingerprint Analysis of Selected Cirsium Species with Aid of Chemometrics
Twelve Cirsium sp. methanolic extracts were analyzed using high-performance liquid chromatography gradient elution method with run time of 45 min. Four Kinetex (150 × 4.6 mm) chromatographic columns (C18 5 µm, C18 2.6 µm, pentafluorophenyl 5 µm, phenyl-hexyl 5 µm) and mobile phase consisting of methanol/water/formic acid 1% were used. Eight standards (n

15. A COMPARATIVE STUDY BETWEEN ARTIFICIAL NEURAL NETWORK AND SUPPORT VECTOR MACHINE FOR ACUTE CORONARY SYNDROME PROGNOSIS
ABSTRACT Despite medical advances, mortality due to acute coronary syndrome remains high. For this reason, it is important to identify the most critical factors for predicting the risk of death in patients hospitalized with this disease. To improve medical decisions, it is also helpful to construct models that enable us to represent how the main driving fact

16. Fe3+-SELECTIVE ENHANCED FLUORESCENCE PROBE BASED ON A RHODAMINE DERIVATIVE
A novel Fe3+-selective and turn-on fluorescent probe 1 incorporating a rhodamine fluorophore and quinoline subunit was synthesized. Probe 1 displayed high selectivity for Fe3+ in CH3CN–H2O (95:5 v/v) in the presence of other relevant metal cations. Interaction with Fe3+ in 1:1 stoichiometry could trigger a significant fluorescence enhancement due to the fo

17. Genetic divergence among cupuaçu accessions by multiscale bootstrap resampling
This study aimed at investigating the genetic divergence of eighteen accessions of cupuaçu trees based on fruit morphometric traits and comparing usual methods of cluster analysis with the proposed multiscale bootstrap resampling methodology. The data were obtained from an experiment conducted in Tomé-Açu city (PA, Brazil), arranged in a completely random

18. Automatic segmentation and classification of blood components in microscopic images using a fuzzy approach
INTRODUCTION: Automatic detection of blood components is an important topic in the field of hematology. Segmentation is an important step because it allows components to be grouped into common areas and processed separately. This paper proposes a method for the automatic segmentation and classification of blood components in microscopic images using a genera

19. Assessment of som (Persea bombycina) clones for resistance against Phyllosticta persae
Som (Persea bombycina) is an economically important tree used as food source by the muga silkworm, Antheraea assamensis. Phyllactinia leaf spot (PLS), caused by Phyllosticta persae, affects all som cultivars during June to September (rainy season) and is responsible for foliage losses up to 26%. Information about the effect of this disease at the farmer leve

20. Cluster evaluation of Brazilian and Moroccan goat populations using physical measurements
The aim of this study was to compare the genetic diversity of 12 populations of goats in Brazil and Morocco (n = 796) through the use of physical measurements and different multivariate techniques. Traits measured included wither height (WH), distance from the brisket to the ground (BH) and ear length (EL). The standardized Euclidean distance (D) was adopted

21. Interspecific variation in the allelopathic potential of the family Myrtaceae
Allelopathy is a type of biotic interference wherein a plant releases bioactive metabolites into an environment, thereby affecting the adjacent biota. Stressful environments stimulate the production of these metabolites. The present study tests the novel weapons hypothesis, which postulates that species belonging to the same genus and from the same environme

22. Modelos de distribuição de espécies de vellozia (Velloziaceae) endêmicas da Cadeia do Espinhaço e o efeito amostral sobre os mapas preditivos
The effectiveness of conservation actions depends on the knowledge of the geographical distribution of species. However, this knowledge is far from being achieved for most species, especially those occurring in mountainous tropical environments, such as the rocky fields (campos rupestres) of the Espinhaço Range, characterized by forming islands of vegetatio

23. Divergence of the fermentative and bromatological characteristics of 25 sorghum hybrid silages
The objective of this study was to evaluate the divergence of bromatological and fermentative characteristics of silages of 25 sorghum (Sorghum bicolor L. Moench) hybrids. The experimental design was completely randomized with 25 treatments and four replications. The mean values of pH differed with variation from 3.45 to 3.87 for hybrids 866005 and 870051, r

24. Monitoring sugar cane crops through dtw-based method for similarity search in NDVI time series.
Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. Due to the strategical importance of this agricultural commodity, it is necessary to improve models that assist the crops monitoring process. Recently, remote sensing images have also been used to crops monitoring. Vegetation index ima
