1. Morphoagronomic characterization of a germplasm collection of Furcraea spp. and Agave spp.
ABSTRACT This work was carried out in Antioquia, Colombia, in a collection of the Furcraea and Agave genera, important in the country for manufacturing strings, sacks, geotextiles, and handicrafts Currently, to enhance its use, applications have been developed in textiles, biodegradable materials and thermo-acoustic insulation, among others. The aim of this

2. Land-use influence on the soil hydrology: An approach in upper Grande River basin, Southeast Brazil
RESUMO A Bacia do Alto Grande (ARG) é responsável pela drenagem de vários rios no sudeste do Brasil, sendo uma região hidrológica de grande importância para o Sistema Elétrico Brasileiro. Portanto, estudos sobre a disponibilidade de água nesta região são indispensáveis para uma melhor tomada de decisão na gestão dos recursos hídricos. O objetiv

4. TEMPORAL VARIATION AND SPATIAL DISTRIBUTION OF RELATIVE INDICES OF LEAF CHLOROPHYLL IN GRAPEVINE cv. CHARDONNAY
ABSTRACT Variation in the spatial distribution of leaf chlorophyll content associated with the progression of the phenological cycle of crops may occur in cultivated areas as a result of the variability of environmental conditions and of the intrinsic properties of the plants. The objective of the present study was to model the trend in variation and assess

5. Ex situ initial seedling development of Hymenaea courbaril L. (Fabaceae): a crucial phase to preserve the species
RESUMO Hymenaea courbaril L. é uma importante espécie Neotropical, que aparece com baixa densidade populacional, restrita a fragmentos de florestas semidecíduas, com baixa mortalidade e baixo recrutamento. Assim, algumas questões orientaram os objetivos deste trabalho, incluindo a capacidade de sementes armazenadas para formar mudas normais. Sementes col

6. Comparative cytogenetic analysis in Erythrolamprus snakes (Serpentes: Dipsadidae) from Argentina
ABSTRACT We described the karyotypes of five snake taxa from Argentina: Erythrolamprus almadensis, E. ceii, E. poecilogyrus caesius, E. p. schotti and E. p. sublineatus, and also intergrading individuals between the last two subspecies by conventional staining, chromosome bandings and fluorescent in situ hybridization (FISH) with 28S ribosomal DNA probes.

7. Real time and in situ Near-Infrared Spectroscopy (Nirs) for Quantitative Monitoring of Biomass, Glucose, Ethanol and Glycerine concentrations in an alcoholic fermentation
Abstract This study investigates the application of NIR spectroscopy for real-time monitoring of process parameters in alcoholic fermentations. For this purpose, fermentation batches using Saccharomyces cerevisiae were carried out and monitored in situ by an immersed NIRS probe. Samples were collected throughout the fermentations, and concentrations of bioma

8. Isotopic variation among Amazonian floodplain woody plants and implications for food-web research
Isotopic variation within food sources adds uncertainty to models intended to reconstruct trophic pathways. Understanding this variation is pivotal for planning sampling protocols for food-web research. This study investigates natural variation in C and N stable isotopes among plant species in two western Amazon flooded forests with contrasting watershed bio

9. Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review
OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, a

10. Chromosome mapping of ribosomal genes and histone H4 in the genus Radacridium (Romaleidae)
In this study, two species of Romaleidae grasshoppers, Radacridium mariajoseae and R.nordestinum, were analyzed after CMA3/DA/DAPI sequential staining and fluorescence in situ hybridization (FISH) to determine the location of the 18S and 5S rDNA and histone H4 genes. Both species presented karyotypes composed of 2n = 23, X0 with exclusively acrocentric chrom

11. Chromosomal divergence and evolutionary inferences in Rhodniini based on the chromosomal location of ribosomal genes
In this study, we used fluorescence in situ hybridisation to determine the chromosomal location of 45S rDNA clusters in 10 species of the tribe Rhodniini (Hemiptera: Reduviidae: Triatominae). The results showed striking inter and intraspecific variability, with the location of the rDNA clusters restricted to sex chromosomes with two patterns: either on one

12. Characterization of Brazilian accessions of wild Arachis species of section Arachis (Fabaceae) using heterochromatin detection and fluorescence in situ hybridization (FISH)
The cytogenetic characterization of Arachis species is useful for assessing the genomes present in this genus, for establishing the relationship among their representatives and for understanding the variability in the available germplasm. In this study, we used fluorescence in situ hybridization (FISH) to examine the distribution patterns of heterochromatin
