Slow-release of methanogenic inhibitors derived from encapsulated calcium carbide using paraffin wax and/or rosin: matrix optimization and diffusion characteristics.
Waste Manag Res 29(11) , 1197-204, (2011) Acetylene has been found to significantly inhibit biological activity of methanogens and thus might be applicable for reducing the generation and emission of methane from municipal solid waste landfills. However, acetylene is gaseous and so it is considered p... |

[Optimization on slow-release inhibition of biomethane and the kinetics model of diffusion].
Huan Jing Ke Xue 31(7) , 1689-94, (2010) The diffusion mechanism of acetylene,which can inhibit the activity of methanogens, was studied. Paraffin wax and rosin were used as matrix of slow-release and calcium carbide was used as inhibition material. Based on the T. Higuchi equation and the character... |

Rapid resolution liquid chromatography (RRLC) analysis for quality control of Rhodiola rosea roots and commercial standardized products.
Nat. Prod. Commun. 6(5) , 645-50, (2011) A simple, sensitive and reliable reversed phase Rapid Resolution Liquid Chromatography (RRLC) method was developed and validated for six biologically active compounds (salidroside, tyrosol, rosarin, rosavin, rosin and rosiridin) in Rhodiola rosea L. roots and... |

Chemical profile of the organic residue from ancient amphora found in the Adriatic Sea determined by direct GC and GC-MS analysis.
Molecules 16(9) , 7936-48, (2011) An ancient organic residue was collected from the bottom of a Greco-Italian amphora found in the Adriatic Sea and investigated by direct GC and GC-MS analysis. The headspace composition was determined by HS-SPME using: (1) DVB/CAR/PDMS and (2) PDMS/DVB fibres... |

Chemical composition of natural colophony from Pinus brutia and comparison with synthetic colophony.
Nat. Prod. Commun. 5(11) , 1729-32, (2010) The compositions of colophony resins obtained from Pinus brutia Ten trees by three different methods (acid paste, carved hole and scraping) from Ayvacik, Gökova and Kemalpaşa in Turkey were analyzed by capillary GC-MS. The main components were the monoterpene... |

Positive concomitant test reactions to allergens in the standard patch test series.
Int. J. Dermatol. 49(5) , 517-9, (2010) Patch testing is performed to evaluate suspected allergic contact dermatitis. Common wisdom suggests that various allergens cross-react but only a few larger studies have published confirmations of this. The purpose of our study was to identify significant co... |
