The detection of hydrogen sulfide (H₂S) and ethanediamine, toxic gases that are emitted from industrial processes, is important for health and safety. An optical sensor, based on the absorption spectrum of tetrakis(4-nitrophenyl)porphyrin (TNPP) immobilized in a Nafion membrane (Nf) and deposited onto an optical waveguide glass slide, has been developed for the detection of these gases. Respons...
We derived a simple model that relates the classification of biogeoclimatezones, (co)existence and fractional coverage of plant functional types (PFTs), and patternsof ecosystem carbon (C) stocks to long-term average values of biogeoclimatic indices in atime- and space-varying fashion from climate-vegetation equilibrium models. ProposedDynamic Ecosystem Classification and Productivity (DECP) mo...
In this study, cellulose nanocrystals (CNC) was prepared and meso-tetrakis(4-nitrophenyl)porphyrin (TNPP) was immobilized on it. The product was identified by techniques of UV-Vis, fourier transform infrared (FT-IR), diffuse reflectance UV-Vis spectroscopy (DRS), energy-dispersive X-ray spectroscopy (EDX) and scanning electron microscopy (SEM). The effect of an amount of a loaded porphyrin comp...
in this study, 5,10,15,20-tetrakis(4-nitrophenyl)porphyrin (tnpp) and its zinc porphyrin complex (zntnpp) were synthesized in situ using the microwave method and identified by uv-vis, ft-ir and 1h nmr. the photostability and photodynamic antimicrobial activity (pact) of these compounds were investigated on pseudomonas aeruginosa and bacillus subtilis under visible light irradiation. mic, mbc an...

Growth and yield data from a loblolly pine plantation in southeastern Louisiana were obtained yearly from 1993 to 1996 on numbered trees within two stands initially planted on a by spacing, and two stands planted on a by spacing. Using allometric equations derived from a 1994 on-site destructive harvest, cited nitrogen concentrations of various tree tissues, and accounting for foliar nitrogen r...
