1. Bioaccumulation, Growth and Photosynthetic Response of a New Found in Bulgaria Invasive Species Lemna minuta and L. valdiviana to Heavy Metal Pollution
RESUMO: Metais pesados podem ser encontrados no meio ambiente como ingredientes naturais ou de práticas agrícolas, industriais e químicas. Este estudo foi conduzido com o objetivo de traçar o potencial das plantas aquáticas L. minuta e L. valdiviana para a bioacumulação de Cu, Cd e Pb a partir de água contaminada com baixos níveis desses elementos.

3. Production and characterization of a biosurfactant produced by Streptomyces sp. DPUA 1559 isolated from lichens of the Amazon region
Surfactants are amphipathic compounds containing both hydrophilic and hydrophobic groups, capable to lower the surface or interfacial tension. Considering the advantages of the use of biosurfactants produced by microorganisms, the aim of this paper was to develop and characterize a biosurfactant produced by Streptomyces sp. DPUA1559 isolated from lichens of

4. Effects of Transplanting Time on 15-Nitrogen Utilization and Industrial Quality of Flue-Cured Tobacco
Abstract Nicotine concentration is a key index and directly affects the industrial quality and availability of flue-cured tobacco (FCT). Seedlings transplanted at different times were subjected to different climatic conditions, which were closely correlated with the growth, development, and nicotine synthesis of FCT. An appropriate transplanting time is impe

5. Preparation and Characterization of Nanowhiskers Cellulose from Fiber Arrowroot (Maranta arundinacea)
The agribusiness generates countless sources of biomass that are not appropriately and / or adequately utilized, turning them into industrial wastes. This study aims to explore the Arrowroot fiber as a source of raw material for the cellulose nanowhiskers production by acidic hydrolysis. Hydrolyses were carried out varying the temperature and the sulfuric ac

6. OPTIMIZATION OF THE OPERATING CONDITIONS FOR RHAMNOLIPID PRODUCTION USING SLAUGHTERHOUSE-GENERATED INDUSTRIAL FLOAT AS SUBSTRATE
AbstractBiosurfactants have a wide range of applications in emulsions, separations, and solubilization because these chemicals reduce the surface tension and viscosity of solutions. This work studied rhamnolipid production using a batch bioreactor with a working volume of 1.5 liters, Pseudomonas aeruginosa ATCC (American Type Culture Collection) 10145 strain

7. Degradation of organic pollutants and characteristics of activated sludge in an anaerobic/anoxic/oxic reactor treating chemical industrial wastewater
A laboratory-scale anaerobic/anoxic/oxic system operated at the hydraulic retention times (HRT) of 20, 40, and 60 h with mixed liquor suspended solids (MLSS) concentrations of 3 g/L and 6 g/L was considered for treating chemical industrial wastewater rich in complex organic compounds and total dissolved solids. Extending the HRT and increasing the MLSS conce

8. Alterations of palm oil (Elaeis guineensis) in the continuous industrial par frying of breaded chicken snacks
The physical and chemical alterations in palm oil during continuous industrial par frying of breaded chicken snacks were evaluated using a pseudo first-order kinetic model. The acidity index, refractive index, concentration of polar compounds, viscosity, color, and absorbance (232 and 268 nm) of 238 samples of the frying oil collected during 26 days of produ

9. Avaliação da contaminação de córregos de Cerrado por metais pesados utilizando-se larvas de Odonata como bioindicadores / Assessment of heavy metal contamination in Brazilian savannas streams using Odonata larvae as bioindicators
The aquatic ecosystems are the main receptors of pollutants and contaminants from industrial and agricultural activities and of the discharge of sewage. Among the various substances potentially harmful, heavy metals are a threat to the aquatic ecosystems and the biota. This research aimed to evaluate the contamination of Cerrados streams by heavy metals usin

10. O COMPORTAMENTO DO SETOR DE TELEFONIA MÃVEL BRASILEIRO APÃS A PRIVATIZAÃÃO DAS TELECOMUNICAÃÃES / THE BEHAVIOR OF BRAZILIAN MOBILE SECTOR AFTER PRIVATIZATION OF TELECOMMUNICATIONS
A privatizaÃÃo do setor de telecomunicaÃÃes, no Brasil, provocou mudanÃas estruturais nesse mercado, que passou de monopÃlio estatal a uma estrutura prÃxima de mercados competitivos. A fim de comprovar essa noÃÃo de desconcentraÃÃo, calcularam-se, para o setor de telefonia mÃvel, algumas medidas de concentraÃÃo industrial, quais sejam: Market S
