| 1 | Degradation of malathion by Pseudomonas during activated sludge treatment system using principal component analysis (PCA)显示文摘Popular descriptive multivariate statistical method currently employed is the principal component analyses (PCA) method. PCA is used to develop linear combinations that successively maximize the total variance of a sample where th ere is no known group structure. This study aimed at demonstrating the performan ce evaluation of pilot activated sludge treatment system by inoculating a strain of Pseudomonas capable of degrading malathion which was isolated by enrichment technique. An intensive analytical program was followed for evaluating the effic iency of biosimulator by maintaining the dissolved oxygen (DO) concentration at 4.0 mg/L. Analyses by high performance liquid chromatographic technique revealed that 90% of malathion removal was achieved within 29 h of treatment whereas COD got reduced considerably during the treatment process and mean removal efficien cy was found to be 78%. The mean pH values increased gradually during the treatm ent process ranging from 7.36—8.54. Similarly the mean ammonia-nitrogen (NH3-N) values were found to be fluctuating between 19.425—28.488 mg/L, mean nitrite-n itrogen (NO3-N) ranging between 1.301—2.940 mg/L and mean nitrate-nitrogen (NO3 -N) ranging between 0.0071—0.0711 mg/L. The study revealed that inoculation of bacterial culture under laboratory conditions could be used in bioremediation of environmental pollution caused by xenobiotics. The PCA analyses showed that pH, COD, organic load and total malathion concentration were highly correlated and emerged as the variables controlling the first component, whereas dissolved oxyg en, NO3-N and NH3-N governed the second component. The third component repeated the trend exhibited by the first two components. | Hashmi Imran Khan M Altaf Kim Jong-Guk | 2006 | Journal of Environmental Sciences2006，18，4： | 3 |
| 2 | Structural, electronic, and optical properties of ZnO_(1-x)Se_x alloys using first-principles calculations显示文摘The structural, electronic, and optical properties of binary ZnO, ZnSe compounds, and their ternary ZnO 1-x Se x alloys are computed using the accurate full potential linearized augmented plane wave plus local orbital (FP-LAPW + lo) method in the rocksalt (B1) and zincblende (B3) crystallographic phases. The electronic band structures, fundamental energy band gaps, and densities of states for ZnO 1-x Se x are evaluated in the range 0 ≤ x ≤ 1 using Wu-Cohen (WC) generalized gradient approximation (GGA) for the exchange-correlation potential. Our calculated results of lattice parameters and bulk modulus reveal a nonlinear variation for pseudo-binary and their ternary alloys in both phases and show a considerable deviation from Vegard's law. It is observed that the predicted lattice parameter and bulk modulus are in good agreement with the available experimental and theoretical data. We establish that the composition dependence of band gap is semi-metallic in B1 phase, while a direct band gap is observed in B3 phase. The calculated density of states is described by taking into account the contribution of Zn 3d, O2p, and Se 4s, and the optical properties are studied in terms of dielectric functions, refractive index, reflectivity, and energy loss function for the B3 phase and are compared with the available experimental data. | Muhammad Rashid Fayyaz Hussain Muhammad Imran S A Ahmad N A Noor M U Sohaib S M Alay-e-Abbas | 2013 | Chinese Physics B2013，22，8： | 2 |
