A two-layer feed forward neural network was successfully applied to predict the adsorptive removal of textile dye direct blue 86 using microwave assisted activated carbon. The Levenberg–Marquardt back-propagation method was used to train the artificial neural network (ANN) at various experiment...

This work tests the viability of applying ozone (O3) and O3 combined with ultraviolet (UV) to degrade the content of synthetic wastewater containing Direct Blue 86 (DB-86) dye. The tested parameters, which included pH, initial concentration of DB-86 dye and time of reaction, were tested in a bat...

NiFe2O4 fusiformis was derived from Ni/Fe bimetal metal-organic frameworks (MOFs) precursors prepared using a facile hydrothermal method, and the corresponding morphology, microstructure, and gas sensing properties were investigated. After thermal treatment at 350 °C in air, the Ni/Fe MOFs elli...

Xylenes are common aromatic volatile organic compounds, which can cause severe environmental pollution and healthy issues. The current instrumental detection methods are generally expensive, time-consuming, complex, and unable to be used for on-site detection. It is thus highly desirable to deve...

The compressed liquid viscosities of ortho-xylene, meta-xylene, para-xylene and ethylbenzene were measured using a vibrating-wire viscometer at different temperatures and pressures. The measurements were performed over the temperature ranges of (273 to 373) K for o-xylene and m-xylene, (293 to 3...

Organic solvent-resistant microorganisms are strongly desired for efficient fermentative production of hydrophobic substances in water-organic solvent two-phase systems. To improve organic solvent-resistance of microorganisms, a better understanding of the effects of organic solvents on microbia...

Even at trace concentrations the presence of heavy hydrocarbons such as BTEX compounds (benzene, toluene, ethylbenzene, and xylenes) in liquefied natural gas (LNG) production streams poses a significant risk of blockage and eventually plant shutdown. However, although p-xylene has the highest me...

In this study, isothermal saturation method was used to measure and correlate the solubility of musk xylene in ten organic solvents at temperatures ranging from 278.15 K to 313.15 K , including methanol, ethanol, isopropanol, n-butanol, cyclohexane, n-hexane, n-heptane, N,N-dimethylacetamide, et...

BackgroundTo examine psychoacoustics in mice, we have used 2,2,2-tribromoethanol anesthesia in multiple studies. We find this drug is fast-acting and yields consistent results, providing 25–30 min of anesthesia. Our recent studies in binaural hearing prompted development of a regimen to anesthe...

Poly(alkyl methacrylate)s (alkyl = methyl, ethyl, n-butyl and n-hexyl) synthesized by Atom Transfer Radical Polymerization (ATRP) using 2,2,2 tribromoethanol as initiator present a first mass loss below 200 °C in thermogravimetric experiments. In order to investigate the possible mechanism of t...

A moderate red wine consumption and a colored fruit-rich diet protect the cardiovascular system, thanks to the presence of several polyphenols. Malvidin-3-0-glucoside (malvidin), an anthocyanidine belonging to polyphenols, is highly present in red grape skin and red wine. Its biological activity...

Vascular inflammatory responses are key mediators of endothelial dysfunction that leads to various pathologies in many diseases including atherosclerosis and cancer. The purpose of the study was to investigate the effects and molecular mechanisms of Malvidin, a natural pigment with strong antiox...

UV-A radiations are known to induce cellular oxidative stress, leading to premature skin aging. Consumption of açai fruit (Euterpe oleracea Martius) is known to have many health benefits due to its high level of antioxidants. Herein, we analyzed the ability of phenolic compounds extracted from t...

We recently demonstrated that California table grapes and a methanol-extractable, polyphenol-rich fraction decreased adiposity, insulin resistance, or markers of inflammation in high-fat fed mice. Malvidin and peonidin glycosides were the 2 most abundant anthocyanins in the polyphenol-rich fract...

BackgroundAnthocyanidins are plant phytochemicals found at high concentrations in berries, vegetables and flowers. Anthocyanidins have been extensively investigated due to their antioxidative, antidiabetic and anti-inflammatory effects. Few studies show that anthocyanidins decrease obesity and i...

Quantum dots (QDs) can be used for a wide range of practical applications including solar energy conversion, light-emitting display, bio-imaging, and sensing. However, toxic heavy metal elements of Pb- and Cd-based QDs cause potential environmental problems and limit their wide applicability. To...

Photodynamic therapy (PDT) is a new treatment modality that uses porphyrin derivatives and visible light, especially for the treatment of cancer. However, PDT with certain photosensitisers can cause prolonged skin photosensitization. This is particularly true for Photofrin II (Photofrin)-mediate...

Responses of sea-ice microalgae to changes in light intensity and quality were studied from March to May 1983 on the first-year ice of southeastern Hudson Bay (Canadian Arctic). Photosynthetic parameters PBmax, αB and βB of the ice algae progressively increased throughout the sampling season. ...

Methods are given for obtaining spectral regimes related to algal absorption regions (red, green, violet) and to coastal, underwater light. Amphidinium and Biddulphia maintained for several months in these regimes have the same structure as when maintained in white light except Biddulphia in the...

Twelve species of Hypomyces/Cladobotryum producing red pigments are reported growing in various tropical areas of the world. Ten of these are described as new, including teleomorphs for two previously known anamorphic species. In two species the teleomorph has been found in nature and in three o...
