  • Immobilization with metal hydroxides as a mean to concentrate food patthogens for increasing sensitivity of pcr based detection method

    Immobilization with metal hydroxides as a mean to concentrate food patthogens for increasing sensitivity of pcr based detection method

    Cố định vi khuẩn bằng hydroxide kim loại làm tăng độ nhạy của phương pháp PCR khi phát hiện vi khuẩn trong thực phẩm. Vi khuẩn ở nồng độ thấp không qua nuôi dưỡng có thể phát hiện được bằng phương pháp PCR nhờ cô đặc vi khuẩn từ thực phẩm bằng hydroxide kim loại. Enzyme DNase I được sử dụng để loại bỏ DNA từ vi khuẩn sống, do đó phương...

  • Using a combination of theoretical descriptors and a neural network to predict the activity of a set of N-alkyl-n-acyl- -aminoamide derivatives

    Using a combination of theoretical descriptors and a neural network to predict the activity of a set of N-alkyl-n-acyl- -aminoamide derivatives

    A back -propagation artificial neural net has been trained to estimate the activity values of a set of 18 N-alkyl-N-acyl- -aminoamide derivatives from the results of molecular mechanics and RHF/PM3/SCF MO semi-empirical calculations. The input descriptors include molecular properties such as the partition coefficient P, 3d structure dependent parameters, charge dependent parameters, and topological descriptors.

  • Plasma-Induced Graft Polymerization of Acrylic Acid onto Poly (ethylene terephthalate) Films: Hydrophilic Modification

    Plasma-Induced Graft Polymerization of Acrylic Acid onto Poly (ethylene terephthalate) Films: Hydrophilic Modification

    A complete and permanent hydrophilic modification of poly (ethyleneterephthalate) (PET) films is achieved by argon-plasma irradiation, subsequently grafting acrylic acid (AA) in vapor phase onto their surface. Both Ar plasma irradiation alone and post grafting AA rendered a complete hydrophilicity to PET surfaces. However, the hydrophilicity of the PET surface, only treated with the Ar plasma, is not permanent. In contrast, PET films,...

  • Limiting Mechanisms of Thermal Transport in Carbon Nanotube-Based Heterogeneous Media

    Limiting Mechanisms of Thermal Transport in Carbon Nanotube-Based Heterogeneous Media

    The outstanding thermal properties of carbon nanotubes (CNTs) have generated considerable interest and research activity. A very promising application is the use of vertically aligned arrays of CNTs as thermal interface materials (TIMs) for electronic systems.

  • Synchrous Machine

    Synchrous Machine

    With the development of the technology and the way in which human labour is getting minimized and the comforts increasing tremendously the use of electrical energy is ever increasing.... The AC voltages generated may be single phase or 3-phase depending on the power supplied. For low power applications single phase generators are preferable. The basic principles involved in the production of emf and the constructional details of the generators...
