Genetic networks are typically composed of a series of connected motifs that confer specific logic and dynamic properties to the resulting circuits. While some feed forward loop (FFL) variants abound in such networks, others (e.g. the type-4 incoherent FFL or
The regulatory and metabolic networks that rule biodegradation of pollutants by environmental bacteria are wired to the rest of the cellular physiology through both transcriptional factors and intermediary signal molecules. In this review, we examine some formalisms for describing catalytic/regulatory
Analytical sciences : the international journal of the Japan Society for Analytical Chemistry, 24(8), 963-966 (2008-08-12)
An analytical method, based on separation with gas chromatography (GC) and detection with optical fiber (OF), was used for the separation, detection and quantification of benzene, toluene, ethylbenzene, p-xylene, m-xylene and o-xylene. The use of OF as a detector is
Titanium dioxide (TiO(2)) is a preferred catalyst for photocatalytic oxidation of many air pollutants. In an effort to enhance its photocatalytic activity, TiO(2) was modified by pulsed plasma treatment. In this work, TiO(2) nanoparticles, coated on a glass plate, were
Huan jing ke xue= Huanjing kexue, 32(12), 3623-3627 (2012-04-04)
An ion mobility spectrometer array was designed, in order to broaden the detection range of ion mobility spectrometer and improve the accuracy of compound identification. This instrument was based on the combination of ionization sources of 63Ni positive ion mode
