1. Green Extraction Optimization of Bioactive Compounds from Rosemary (Rosmarinus officinalis L.) Using Response Surface Methodology
Rosemary (Rosmarinus officinalis L.) is known for its bioactive compounds with high antioxidant potential and pharmacological properties, such as antibacterial, antidepressant and anti-inflammatory. These properties are attributed to the presence of (poly)phenolic compounds. In the literature there is no extraction of these compounds with a totally non-toxic

2. POLYETHERIMIDE/POLYVINYLPYRROLIDONE HOLLOW-FIBER MEMBRANES FOR USE IN HEMODIALYSIS
Abstract In this study, polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes (HFMs) were synthesized by the phase inversion method. The synthesized PEI/PVP membranes were characterized by morphological analysis and transport properties (hydraulic permeability and solute rejection coefficient). Their performance in uremic solutes separation wa

3. DEEP EUTECTIC SOLVENTS BASED ON BETAINE AND PROPYLENE GLYCOL AS POTENTIAL DENITRIFICATION AGENTS: A LIQUID-LIQUID EQUILIBRIUM STUDY
Abstract Two deep eutectic solvents (DES) based on betaine (B) and propylene glycol (PG) in molar ratios of 1:4 and 1:5 were prepared and their physico-chemical properties were determined. Liquid-liquid equilibria at 298.15 K and atmospheric pressure were determined for 13 quasi-three-component systems with a hydrocarbon (n-hexane, n-heptane, i-octane or tol

4. Elastic and Osmotic Adjustment of Talipariti elatum (Sw) Frixell Grown in Organic Substrates
ABSTRACT The aim of the present study was to evaluate the water response of Talipariti elatum cultivated in different substrates. Sugarcane straw, peat, biochar and mixtures of sugarcane straw and biochar, and peat and biochar were used. The physical properties of each substrate and the water parameters of the species were determined based on the pressure-v

5. TRANSPORT PARAMETERS OF POTASSIUM FROM DIFFERENT SOURCES IN SOIL COLUMNS
ABSTRACT This study aimed to determine some transport parameters of potassium in soil columns by miscible displacement of effluent from a Sewage Treatment Plant (STP). This effluent was collected at different stages of treatment, and potassium chloride solutions were prepared with the same K pulse concentration as the effluent. They were used to conduct a mi

8. Physiological and biochemical responses to drought stress in Barbados cherry
To evaluate physiological genotypic differences between two Barbados cherry genotypes (13- and 14-CPA) under water deficit, initial growth, water relations, and organic solute accumulation were evaluated in an experiment performed using four-month-old seedlings, which were subjected to four water treatments (100, 75, 50, and 25% of field capacity), with five

9. Accumulation of organic and inorganic solutes in NaCl-stressed sorghum seedlings from aged and primed seeds
Although it has been known that the seed's physiological potential affects its response to osmoconditioning and abiotic stresses, researches involving seed aging and priming associated to abiotic stresses are scarce. The aim of this work was to evaluate the role of seed priming on salt tolerance in sorghum seedlings from seeds with two vigor levels (aged or

10. Termodinâmica de sistemas fullerênicos em soluções / Thermodynamic systems fullerenic solutions
In this work, we present a computational study of the solvation process of the C60 fullerene and its hydroxylated derivate, the fullerenol C60(OH)24, in aqueous environment and organic solvents, using classical molecular dynamics simulations. Diverse sets of parameters to the Lennard-Jones interaction potential have been utilized in simulations of fullerenes

11. Metodologia AGOA: a modelagem de clusters de hidratação no complexo aziridina···ácido fluorídrico
We present a theoretical study of solvent effect on C2H5N···HF hydrogen-bonded complex through the application of the AGOA methodology. By using the TIP4P model to orientate the configuration of water molecules, the hydration clusters generated by AGOA were obtained through the analysis of the molecular electrostatic potential (MEP) of solute (C2H5N···

12. Retenção de metais pesados em solos agricultáveis do Estado de Goiás / Retention of heavy metals in agricultural soils of the State of Goiás
The intensification of the use of land for farming has caused great concern, mainly due to the impacts that these activities are causing the environment, particularly with regard to its contamination by chemicals. The application of chemicals and waste ground and in several, or in plants in order to take agronomically solid waste, improve productivity and in
