The textile industry moves the economy of several countries, being of great importance for the internal market and also for the external market, but it is considered one of the industries that consume a greater volume of water in its productive process, being one of the largest producers of effluents. Effluents from the textile industries carry toxic, mutagenic and potentially carcinogenic substances, and are resistant to chemical and/or biological degradation, pre-venting traditional effluent treatment methodologies from removing significant quantities of these molecules, compromising the quality of receiving water bodies. The present work aims to demonstrate the conventional methodologies used in the treatment of effluents from textile industries and present new technologies discovered for this purpose and present a greater efficiency in the removal of the dyes used in the productive chain of these industries.

Abstract: The Dof (DNA-binding with one finger) proteins are a class of plant-specific transcription factors that can trigger several processes involved in plant growth and development, as well as in stress responses. Here, we performed a systematic bioinformatics analysis to characterize all Dof genes in common bean, which included analysis of the genome sequence, conserved protein domains, chromosomal locations, subcellular locations, phylogenetic relationships, gene duplications, and gene expression profiles in different tissues. Bioinformatics analysis revealed 36 putative genes related to PvDof that were classified into seven subfamilies (A, B1, B2, C1, C2, D1, and, D2) by comparative phylogenetic analysis. Based on our genome duplication analysis, a total of 36 genes were found to be distributed on all 11 chromosomes, and they expanded through gene duplication in tandem, suggesting the involvement of segmental duplication events in the evolutionary process. Synteny events and phylogenetic comparisons of the Dof proteins of common bean with those of A. thaliana, O. sativa, and G. max L. led to the identification of several orthologous and paralogous genes, which provided further insight into the diversity of the evolutionary characteristics of genes of this family in other plant species. Expression profiles revealed that most of the PvDof genes were expressed in different tissues, indicating that PvDof genes may be involved in various physiological functions during plant development. The results of this study provide additional information and potential biotechnological resources for further understanding the molecular basis of this gene family and consequently improvement of common bean crops.

Crop Breeding and Applied Biotechnology , 2009,
Abstract: The consequences of climate change for the agribusiness in Brazil have been widely debated. The issue isdiscussed in this publication to show the expected problems, particularly those associated with increases in temperature andwater stress. It is emphasized that the genetic improvement of plants, based on the experience in the past, has much tocontribute to mitigate these problems. To invest in the breeding of new cultivars, selected under stress conditions, is certainlythe best possible strategy for agriculture to cope with changes caused by climate alterations.

Agricultural Sciences (AS) , 2015, DOI: 10.4236/as.2015.63037
Abstract: Ornamental plants are distinguished by the shape and color of their leaves/flowers and their use in landscaping and gardening. In urban areas, their presence is relevant for the maintenance of bees. Aiming to list the ornamental bee plants species occurring in Santa Catarina State (SC), southern Brazil, a survey of forage resources for bees, recorded in the State, was performed. We refer all published works developed in SC (resulting in the period 1983-2014) which include data from reports of scientific research, monographs, dissertations, Masters Dissertations, Doctoral Thesis, annals of scientific events, scientific articles and books. From the 28 ensuant works, we listed, as ornamental bee plants occurring in SC, 201 species, of 156 genera and 66 botanical families. Of these species, 92 are native (N), 26 endemic to Brazil and 109 exotic (E). Families with more ornamental bee species are: Fabaceae (22 species), Asteraceae (20), Solanaceae (11), Rosaceae (10) and Lamiaceae (8). The most cited species are: Lantana camara L. (N) (Verbenaceae) (9 quotes), Aloysia virgata (N) (Ruiz & Pav.) Juss. (Verbenaceae) (8), Hedychium coronarium J. Koenig (naturalized) (Zingiberaceae) (6) and Brachyscome multifida (E) (Asteraceae) (5), regarding habitus, herbs (48.5%) predominate, followed by bushes (21.5%), trees (16.5%) and vines (10.5%). Preferred colours of flowers by bees are, in decreasing order: white, yellow, red/pink, and others. The genus Ipomoea, Calliandra, Passiflora, Prunus and Senecio have more ornamental bee plant species. A large botanical diversity arises, demonstrating the possibilities for urban bee foraging and ornamental featuring, in a perspective of sustainability.

Abstract: this is a descriptive analytical cross-sectional study conducted with 2282 male and female students who attended high school in three cities of the western interior of s?o paulo, brazil. data collection was done by a self-reported questionnaire with 131 questions. this paper discusses the sexual trajectories of these adolescents who enrolled in homoerotic sexual practices or not. these adolescents’ relationships with their families, peer groups and the subject of “coming out” are discussed as political tools. based on sedgwick’s concepts we analyze the moments when “coming out” can be one in many other ways of manifestation of different sexualities in relation to heteronormativity. relying on post-structuralism theories, we also discuss theoretical constructions and discourses about adolescence, pointing at new manifestations of juvenile in contemporaneity. finally, we realize the existence of many factors that affect the decisions of non-heterosexual youths in relation to “coming out of the closet” beyond homophobia: personal events, life stories and even the revelation of their sexuality to their parents and/or to others.

Revista Brasileira de Pesquisa em Alimentos , 2011,
Abstract: Pequi (Caryocar brasiliense Camb.) is a fruit from Brazilian “cerrado”, whose pulp has a substantial oil content, which represents great economic, nutritional and sensory importance. This oil is mainly constituted by saturated and monounsaturated fatty acids, which gives it a good oxidating stability. The aim of this study was to evaluate the pequi pulp crude oil regarding its quality as comestible vegetable oil. The oil was purchased from the state of Minas Gerais, and subjected to physical and chemical analysis for proper characterization. The results for acid value (3.23 mg KOH/ g), peroxide (11.16 meq/1000 g) saponification (97.58 mg KOH/ g), iodine (60.39%), index of refraction (1.4613), moisture content (1.00%), and instrumental color (L = 64.00 a * = 23.57 b * = 68.04) showed that the pequi pulp crude oil was in good condition, according to current legislation requirements, and with characteristics similar to those previously reported. Thus, the pequi pulp crude oil was qualified as suitable for human consumption, considering the adopted forms of assessment.

Abstract: A simple, reproducible and efficient high-performance liquid chromatography (HPLC) method was developed. Water (0.05% TFA):acetonitrile (0.05% TFA) was used as the mobile phase in a gradient system for the determination of epicatechin (EP) in leaves of Maytenus ilicifolia (Schrad.) Planch. The analysis was performed using an RP C-18 column (5 μm) as the stationary phase, with a flow rate of 0.8 mL/min, at a wavelength of 210 nm for detection and determination. The main validation parameters of the method were also determined. The calibration curve was found to be linear, with a range of 10-120 μg/mL (EP). The correlation coefficient of the linear regression analysis was within 0.9988, and the detection and quantification limits were 28.61 and 86.77 μg/mL, respectively. The content of EP was successfully determined, with satisfactory reproducibility and recovery. Recovery of the EP was 99.32%. The method was successfully applied to the determination of epicatechin in leaves of M. ilicifolia. The interlaboratorial evaluation showed the reproducibility of the method with a relative standard deviation of 14.62%.
