1. Leachate and vinasse used in a biological process combined with Fenton’s reaction: a green method for treatment of textile effluents
Abstract: The production of textiles generates a large amount of liquid residues considered to be environmentally problematic and which, if discarded without due treatment, may cause eutrophication of water sources, the intoxication of living beings, and the blocking of light penetration. Some methods have been applied for the treatment of this type of waste

3. Estudo comparativo do tingimento de malha PES/CO com água tratada com resíduo de clarificação de óleo vegetal, na forma natural e calcinada
RESUMO A indústria têxtil utiliza um grande volume de água, o que torna necessário encontrar opções mais sustentáveis para o seu uso, como a reutilização em novos tingimentos. O uso de um resíduo industrial sólido, como adsorvente, poderá ser uma alternativa para tratar o efluente têxtil. Este estudo teve como objetivo testar a viabilidade do re

4. Increased atmospheric CO2 changes the photosynthetic responses of Acrocomia aculeata (Arecaceae) to drought
ABSTRACT Water availability is the main factor that explains current patterns of palm abundance. However, the interaction between water stress and increasing atmospheric CO2 concentrations caused by climatic change and its effects on palm physiology remain poorly known. Macauba palm is a widespread Neotropical species commonly found in ecosystems subjected t

5. Mitigation of drought stress effects on soybean gas exchanges induced by Azospirillum brasilense and plant regulators
RESUMO O déficit hídrico é limitante à produção agrícola, tendo como efeito primário a redução nas trocas gasosas vegetais, e a continuidade da incidência resulta em menor produtividade. Objetivou-se avaliar as respostas fotossintéticas e a produção de soja sob déficit hídrico severo induzido, em relação à inoculação via semente e aplica

6. APPLICATION OF POLYCARBOXYLIC ACIDS AS BINDERS FOR TiO2 IMMOBILIZATION ON COTTON TEXTILES
ABSTRACT Immobilizing the photocatalyst on a support is an alternative solution to a critical issue in photocatalysis, which is the need for unit operations to remove the photocatalyst from the effluent. In this work, TiO2 was immobilized onto a cotton textile substrate by polycarboxylic acid binders (succinic and citric acids) using a solution deposition me

7. AGRONOMIC PERFORMANCE OF RADISH GENOTYPES UNDER DIFFERENT IRRIGATION DEPTHS
ABSTRACT In radish production, the choice of proper genotypes and irrigation regime is of great importance to achieve success. In light of this, the current study aimed to evaluate the agronomic performance of a few radish genotypes under different irrigation strategies. The plants were grown in the city of Unaí - MG, in Brazil, under field conditions, and

8. New technologies from the bioworld: selection of biopolymer-producing microalgae
Abstract Microalgae are studied because of their biotechnological potential. The growth of microalgae aims at obtaining natural compounds. Due to the large amount of accumulated polymer waste, one of the solutions is the use of biodegradable polymers. The objective of this work was to select biopolymer-producing microalgae and to study the cell growth phase

9. DISEÑO Y CARACTERIZACIÓN TEÓRICA DE MATERIALES FOTOACTIVOS EFICIENTES BASADOS EN DERIVADOS DE NAFTOPIRROL Y DE NAFTOTIOFENO PARA CELDAS SOLARES ORGÁNICAS
In this research we have designed electron donors D-π-A type containing two different π fragments to obtain naphthopyrrole (D-NPR-A) and naphthotiophene (D-NTP-A) derivatives, proposed for the use in organic bulk hetero-junction (BHJ) solar cells (OSCs). These derivatives were characterized by DFT and TD-DFT calculations. For all the electron donors the an

10. Morphological Plasticity and Gas Exchange of Ligustrum lucidumW.T. Aiton in Distinct Light Conditions
ABSTRACT The objective of this study was to understand the different morpho-physiological strategies of Ligustrum lucidum, an invasive species occurring in Brazilian forest fragments under heterogeneous light conditions. Ten individuals of L. lucidum were selected and evaluated for morphological of the leaves and physiological traits. For morphological param

11. Performance of Broilers Reared under Monochromatic Light Emitting Diode Supplemental Lighting
ABSTRACT The purpose of this study was to evaluate the effect of green monochromatic light emitting diodes (LED) or white fluorescent lamps on the growth performance of broilers reared in open houses. Two hundred broilers (Ross 308) were sexed and divided into four treatments, according to sex and supplemental light source: T1, males under green LED; T2, mal

12. Jatropha curcasand Ricinus communisdisplay contrasting photosynthetic mechanisms in response to environmental conditions
Higher plants display different adaptive strategies in photosynthesis to cope with abiotic stress. In this study, photosynthetic mechanisms and water relationships displayed byJatropha curcasL. (physic nuts) andRicinus communisL. (castor bean), in response to variations in environmental conditions, were assessed.R. communis showed higher CO2 assimilation, st
