Influence of Biological Treatment and Ultraviolet Disinfection System on Pseudomonas spp. Diversity in Wastewater as Assessed by Denaturing Gradient Gel Electrophoresis

Biological treatment methods use natural processes of ubiquitous living organisms to improve or upgrade the quality of a wastewater. To investigate the dominance of Pseudomonas spp. community in untreated and treated wastewater from full-scale biodiscs treatment plant, PCR–denaturing gradient gel electrophoresis coupled with sequence analysis of 16S rRNA gene fragments from dominant bands, were performed. The Pseudomonas species distribution over the total treatment process and over seasons (summer and winter) was obtained by comparing the denaturing gradient gel electrophoresis (DGGE) patterns to a normalized mix of nine reference Pseudomonas strains.ResultsindicatedthatPseudomonas putidaand Pseudomonas fluorescensstrainsshowed dominance in wastewater, remarkable stability in the biofilm and resistance to UV irradiation. A reduction of Pseudomonas aeruginosa in treated wastewater was also observed. In addition, climatic and operational conditions results in selection of microbial community. The high temperature and intense solar radiation contribute to the total absence of the Pseudomonas syringae strain. In this work, the effect of increasing UV254 germicidal dose on the Pseudomonas community in secondary treated wastewater effluent was also tested.At a dose of 1200mWs/cm 2 , total disappearance of the band corresponding toP. aeruginosa, was noted. The DGGE approach can be used as an effective method to assess directly the Pseudomonas community shifts in studied wastewater treatment plant.
Studies on Cu/CeO2: A New NO Reduction Catalyst

Fine particle and large surface area Cu/CeO{sub 2} catalysts of crystallite sizes in the range of 100--200 {angstrom} synthesized by the solution combustion method have been investigated for NO reduction. Five percent Cu/CeO{sub 2} catalyst shows nearly 100% conversion of NO by NH{sub 3} below 300 C, whereas pure ceria and Zr, Y, and Ca doped ceria show 85--95% NO conversion above 600 C. Similarly NO reduction by CO has been observed over 5% Cu/CeO{sub 2} with nearly 100% conversion below 300 C. Hydrocarbon (n-butane) oxidation by NO to CO{sub 2}, N{sub 2}, and H{sub 2}O has also been demonstrated over this catalyst below 350 C making Cu/CeO{sub 2} a new NO reduction catalyst in the low temperature window of 150--350 C. Kinetics of NO reduction over 5% Cu/CeO{sub 2} have also been investigated. The rate constants are in the range of 1.4 {times} 10{sup 4} to 2.3 {times} 10{sup 4} cm{sup 3}/g s between 170 and 300 C. Cu/CeO{sub 2} catalysts are characterized by X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, and electron paramagnetic resonance spectroscopy where Cu{sup 2+} ions are shown to be dispersed on the CeO{sub 2} surface.
The Synthesis and Crystal Structure of Doped Uranium Brannerite Phases U1−xMxTi2O6 (M=Ca2+, La3+, and Gd3+)

Doped uranium brannerite phases (U1−xMxTi2O6; M=Ca2+, La3+ and Gd3+; x<0.5) were synthesized at 1400°C; the range of solid solution was found to vary depending on whether sintering took place in argon or air. Powder X-ray diffraction revealed that these phases crystallized to form monoclinic (C2/m) structures. In particular, the crystal structures of U0.74Ca0. 26 Ti2O6 (1) (a=9.8008(2); b=3.7276(1); c=6.8745(1); β=118.38(1); V=220.97(1); Z=2; RP=7.3%; RB=4.6%) and U0.55La0. 45Ti2O6 (2) (a=9.8002(7); b=3.7510(3); c=6.9990(5); β=118.37(4); V=226.40(3); Z=2; RP=4.5%; RB=2.9%) were refined from powder neutron diffraction data, revealing planes of corner and edge-sharing TiO6 octahedra separated by 8-fold coordinate U/M atoms. The oxygen sites within these structures were found to be fully occupied, confirming that the doping of lower valence M atoms occurs in conjunction with the oxidation of U(IV) to U(V).
COSMO-RS-based extractant screening for phenol extraction as model system

The focus of this investigation is the development of a fast and reliable extractant screening approach. Phenol extraction is selected as the model process. A quantum chemical conductor-like screening model for real solvents (COSMO-RS) is combined with molecular design considerations. For this purpose, phenol distribution coefficients KD of known phenol extractants are determined experimentally and in silico. Molecular variations of different extractants are tested concerning their effect on KD to facilitate extractant improvement. It is shown that KD depends on the molecular structure of the extractant. Calculations with COSMO-RS provide a qualitative trend of simulated extraction efficiency and even a quantitatively correct description of KD. The simulations for alkylamine components are, however, not accurate, which is a well-known problem. During the screening process, phosphorus containing aliphatic substances, especially the trialkylphosphine oxide compound Cyanex 923, were determined as the most promising phenol extractants, which agrees with the state of the art.
Bioactive Components of Mexican Oregano Oil as Affected by Moisture and Plant Maturity

Abstract The effect of moisture and plant growth on Mexican oregano (Lippia graveolens HBK) essential oil composition was examined in field trials. Essential oil content of dry oregano leaves was about 2% (w/w). Thymol and carvacrol were the major components in the oil fraction and plant maturity had a significant effect on oil composition. However, moisture effect and plant growth phase/moisture interaction were not significant. Examination of the oil composition of samples collected from three cultivated and one wild oregano type indicated that the oil obtained from wild plants contained significantly lower amount of 1,8-cineole and carvacrol than the cultivated types. The thymol content of the wild variety was higher.
A first-principles study of cementite (Fe3C) and its alloyed counterparts: Elastic constants, elastic anisotropies, and isotropic elastic moduli

A comprehensive computational study of elastic properties of cementite (Fe3C) and its alloyed counterparts (M3C (M = Al, Co, Cr, Cu, Fe, Hf, Mn, Mo, Nb, Ni, Si, Ta, Ti, V, W, Zr, Cr2FeC and CrFe2C) having the crystal structure of Fe3C is carried out employing electronic density-functional theory (DFT), all-electron PAW pseudopotentials and the generalized gradient approximation for the exchange-correlation energy (GGA). Specifically, as a part of our systematic study of cohesive properties of solids and in the spirit of materials genome, following properties are calculated: (i) single-crystal elastic constants, Cij, of above M3Cs; (ii) anisotropies of bulk, Young’s and shear moduli, and Poisson’s ratio based on calculated Cijs, demonstrating their extreme anisotropies; (iii) isotropic (polycrystalline) elastic moduli (bulk, shear, Young’s moduli and Poisson’s ratio) of M3Cs by homogenization of calculated Cijs; and (iv) acoustic Debye temperature, θD, of M3Cs based on calculated Cijs. We provide a critica.
Organic-Inorganic Hybrid Materials for Nonlinear Optics Applications

Abstract Three types of organic-inorganic hybrid materials were prepared by the sol-gel processable monomers derived from 3-isocyanatopropyltriethoxysilane with three different hydroxy-functionalized nonlinear optical chromophores. The measured values of NLO coefficient strongly depended on conditions such as poling temperature, poling time and heating rate. The hybrid films heated at 200°C exhibited d 33 = 50–58 pm/V in Maker-fringe measurement. It was found that the thermal stabilities of the films were greatly enhanced as poling time increased and a poling temperature became higher. Also, we observed good waveguiding properties of the films at 810 nm and 1064 nm. The optical propagation losses of the films for TE mode were about 2 dB/cm at 810 nm and 0.5 dB/cm at 1064 nm.
Budget Deficit and Trade Deficit Causality in the

Budget deficit is defined as the difference between what a government spends and what it collects in taxes in a given period. If the government expenditures exceed revenue, the government must borrow to finance the deficit. In contrast, if government revenue exceeds expenditures, this means that government is spending less than it is collecting in taxes and the government is running a surplus. A budget surplus is simply a negative budget deficit (Case and Fair, 2007). On the other hand, trade deficit occurs when a country’s exports of goods and services are less than its imports of goods and services in a given period. The reverse is called a trade surplus. These two deficits are also known as ‘’twin deficits’’ which appears as ‘’Siamese Twins’’ that could not be separated (Feldstein, 1992).
Stability Limit Determination for Pure Compounds

Abstract The Helmholtz criteria for equilibrium and stability were used with the Peng-Robinson (P-R) equation of state to determine the limits of stability for n-hexane, cyclohexane, and benzene, as representative paraffinic, naphthenic, and aromatic compounds, respectively. The cubic equation that results from the criteria of stability was solved to obtain the three roots of volume at different pressures. The intersection of the stability curve and the temperature isotherm determines the limit of stability for a compound. The stability limits tend to increase with increase in temperature alone for each substance.
INTER-LABORATORY COMPARISON OF SULPHUR AND NITROGEN ANALYSIS IN PLANTS AND SOILS

Ten United Kingdom laboratories participated in a study to evaluate variability of analysis for total concentrations of sulphur (S) and nitrogen (N) in plant materials and extractable S in soil samples. Four plant and two soil samples were prepared and distributed to the participants. Results show that laboratories were in reasonable agreement for analysis of total N in plant materials, with coefficients of variation (CVs) in the range of 2.7–5.4%. In contrast, the inter-laboratory variability for total S was much higher, with CVs varying from 8.2 to 20.3%. The inter-laboratory variability for plant N:S ratio was similar to that for total S, indicating that the reliability of N:S was limited by the accuracy of the S analysis. Large differences (5-fold) between laboratories were reported for extractable S in soil, with CVs of 36–45%. The laboratories used different analytical methods for both soil and plant analyses, but method bias does not seem to explain the large inter-laboratory variability. Diagnosis of S deficiency based on S analysis may be of questionable validity if S analyses results for plant and soil samples are not accurate. To improve analytical reliability, more method development and standardization are needed.

What does traceability mean for beef meat consumer

Post BSE crisis in France was managed with meat traceability as standard. All the beef meat supply chain quickly faced to problems of clear application and economical absorption of traceability. The valorisation with distributors and consumers of this peculiar effort is still unresolved (LATOUCHE et al., 1998). According to the incorporation principle (FISCHLER, 1990) it seems that consumers are likely reluctant to accept technological argument with respect to food. Consumers expectations for high quality beef meat become more oriented towards labelled meat despite a strict trade-off that does not accept high price premium (DRANSFIELD, 1997, VERBERKE & VIÆNE, 1999). Nowadays there is a very high probability of discrepancy between consumer reinsurance needs and the technical way used by the beef meat chain to satisfy such expectations by means of traceability (GRUNERT, 1999).
On the distribution of cell areas in a Voronoi network

Abstract The distribution of cell areas for a Voronoi network is examined by computer simulation, and a rough argument is presented as to how this form of distribution may be derived analytically. The resulting form is a gamma function as was previously used by Kiang (1966) to fit numerical data of cell areas. Computer-generated distributions for large samples of cells are here used to test this suggested function more stringently than in Kiang's work.
RELEASE OF POTASSIUM BY 18 ONTARIO SOILS DURING CONTINUOUS CROPPING IN THE GREENHOUSE

Eighteen Ontario soils were ranked according to their capacity to supply potassium from non-exchangeable forms to eight successive crops of alfalfa. This capacity was found to be closely related to the percentage of clay in the soils. Potassium content of the alfalfa and total uptake of potassium were highly correlated with both exchangeable soil potassium and release of potassium from non-exchangeable forms. Exchangeable potassium levels below 100 lb. per acre gave low yields and potassium content of the crop. Excessively high exchangeable potassium levels resulted in luxury consumption of potassium by the crop or in fixation by the soil. In soils at or near their equilibrium exchangeable potassium levels, i.e., not heavily fertilized, there was a close relationship between potassium-supplying power and the exchangeable potassium content measured either before cropping commenced or at the end of the cropping period.
Effect of electronic correlation on molecules adsorbed on metallic surfaces

The combination of spintronics and organic electronics, is believed to lead to a new generation of spin based devices, which would likely open a new broad range of applications in the field of organic spintronics. ln this context, this work focuses on organic molecules adsorbed on metallic surfaces and their electronic structure changes due to the important screening of the metallic environment. We have studied different systems, starting with a Ni2 complex adsorbed on Cu (001), where Kondo effect sets in. This study is followed by oligoacene chains (fused benzene rings) where an extraordinary property is seen: an oscillation of the energy band gap with respect to the molecular length. This property is proved to survive under the screening of surfaces such as Au(111) and Si02. We finally focused on small molecules, like ethane and ethylene, adsorbed on Cu and Co. The difference of energy between the lowest unoccupied molecular orbital (LUMO) and the highest occupied molecular orbital (HOMO) is studied using density functional theory (DFT)and GW methodologies.
PREPARATION OF CaCO3 PARTICLES IN WATER POOL IN NONAQUEOUS NONIONIC SURFACTANT SOLUTIONS

ABSTRACT CaCO3 particles were prepared by bubbling of CO2 into the systems consisting of polyoxyethylene(6) nonylphenyl ether/aqueous Ca(OH) 2/cyclohexane. Spherical particles were formed in any systems, but those size distribution depended on the solubility behavior of aqueous Ca(OH) 2 in surfactant solutions, i.e., monodisperse particles were formed in colorless solution, whereas in blue translucent solution they became bimodal. Such change was also observed for the size of reversed micelles. This suggested that the formation of CaCO3 particles were related with that of micelles. On the other hand, the particles obtained were consisted of calcite, vaterite and aragonite. Those fraction differed also from the solubility behavior of aqueous Ca(OH) 2. Both the vaterite and aragonite were transformed into calcite and those rate constants were order of 10−6 sec−1.
A Combined Site‐Specific Metals Sorption and Transport Model for Intact Soil Columns

Simulation of metal attenuation in natural soil environments requires model descriptions of combined sorption and transport processes that are generally transferable to assess potential risk. A non‐electrostatic equilibrium ion exchange and surface complexation model (SCM), developed from batch experiments of Pb and Cd sorption to natural soils, was used to describe coupled transport in undisturbed soil column experiments. The model, based on soil mineral component additivity, was applied to reproduce metal transport without adjustment of sorption reactions or conditional equilibrium constants derived from batch experiments. Good agreement between model results and experimental soil column data for Pb and Cd uptake and release indicates that their transport at two different concentrations and flow rates can be described by sorption equilibria except for Pb at low concentration and slow flow rate. Model simulations were less successful in describing the transport behavior of Ca and Al, and effluent acidic pH, suggesting that additional reactions involving Al are needed. Fluctuations in effluent pH were not well simulated by the model, but model results were within ∼0.25 to 0.5 log units of observed pH. Model results suggest that sorption competition between Pb, Cd, and Ca (from the background electrolyte) was mostly associated with ion exchange sites attributed to weathered illite at acidic pH, with additional adsorption of Pb on hydroxyl sites of extractable Fe‐oxides. Simulations predicted net retention of Pb and Cd by soil columns from −9% to +13% of observed metal retention. This study demonstrates the ability to transfer a relatively small set of equilibrium sorption reactions and constants from batch to hydrodynamic column experiments under a limited set of flow conditions without arbitrary parameter fitting by using soil properties and mineralogy as constraints in model formulation.
Atrazine biotransformation in wetland sediment under different nutrient conditions‐i: Anaerobic

Abstract Anaerobic biotransformation of atrazine under three different nutrient conditions, i.e., D.I water, wetland water, and basal salt media (BSM), was investigated with the sediment from a wetland receiving sugar mill wastewa‐ter in Louisiana. None of the well‐known metabolites and their hydroxy analogs, except hydroxyatrazine were detected in all sample reactors. About 50% of 10 mg/L of atrazine disappeared after 38 weeks of incubation from liquid and sediment phases of the sample reactors with D.I. water and wetland water. However, more than 25% of the disappeared atrazine still existed as hydroxyatrazine in those sample reactors. BSM substantially increased the removal rate of atrazine. Atrazine concentrations dropped to less than detectable level after 38 weeks of incubation in the sample reactors with BSM. However, the hydroxyatrazine level in liquid and sediment phases of the BSM reactors was still about 2.5 mg/L. BSM without (NH4)2SO4 decreased the atrazine transformation rate.
Field dependence of impact ionization coefficients in In/sub 0.53/Ga/sub 0.47/As

Electron and hole ionization coefficients in In/sub 0.53/Ga/sub 0.47/As are deduced from mixed carrier avalanche photomultiplication measurements on a series of p-i-n diode layers, eliminating other effects that can lead to an increase in photocurrent with reverse bias. Low field ionization is observed for electrons but not for holes, resulting in a larger ratio of ionization coefficients, even at moderately high electric fields than previously reported. The measured ionization coefficients are marginally lower than those of GaAs for fields above 250 kVcm/sup -1/, supporting reports of slightly higher avalanche breakdown voltages in In/sub 0.53/Ga/sub 0.47/As than in GaAs p-i-n diodes.
Thermoelectric properties of Al–Pd–Re quasicrystal sintered by Spark Plasma Sintering (SPS): effect of improvement of microstructure

Abstract We report the thermoelectric properties of poly-grain Al–Pd–Re icosahedral quasicrystals and discuss an effect of improvement of their microstructure. The improvement of microstructure by using Spark Plasma Sintering (SPS) method resulted into a large increase of the electrical conductivity but less increase of the thermal conductivity. The relative density dramatically increased up to more than 90% by SPS. On the other hand, the microstructure itself does not have critical influence on the Seebeck coefficient, which is found to be strongly correlated with e/a (sample’s compositions). Consequently, the dimensionless figure of merit (ZT) increased three times from 0.05 to 0.15.
Evaluation of few insecticides against insect pests of cashew

Efficacy of certain insecticides against cashew insect pests was tested in the experimental farm of the Regional Research Centre, BCKV, Jhargram during 2014-15 and 2015-16. Among the insecticides applied Lambda cyhalothrin @ 0.003% showed maximum efficacy to control leaf and blossom webber (9.57%) and leaf miner (8.4%) of cashew 30 days after first spray while acetamiprid @0.01% was also reported equally effective against the same insects and were statistically at par. Acetamiprid (0.01%) was recorded as most effective treatment to control apple and nut borer with 2.89% of damage which was closely followed by lambda cy-halothrin (2.97%) at 30 days after third spray. The trees treated with Neem oil soap @ 4% followed by Lambda Cyhalothrin @ 0.003% followed by again Neem oil soap was recorded superior to control thrips over the other treatments applied. However, imidacloprid @ 0.011% was recorded as least effective treatment to control cashew insects in the present study.
Molecular Dynamics Study of Gas−Liquid Aqueous Sodium Halide Interfaces. II. Analysis of Vibrational Sum Frequency Generation Spectra

The vibrational sum frequency generation (SFG) spectra of gas−liquid interfaces of NaCl and NaI aqueous solutions are computed and analyzed by molecular dynamics (MD) simulations using a flexible and polarizable molecular model. The MD calculations have reproduced the experimental features of SFG spectra, including observed perturbation on the NaI spectra in contrast to little perturbation on NaCl. Analysis of the nonlinear susceptibility revealed that the intermolecular correlation has a significant contribution to the vibrationally resonant amplitude, which largely distorts the generally accepted relationship between the SFG intensity and orientation of individual molecules. In NaI solutions, modest enhancement of ssp intensity in the 3400 cm-1 region is thereby elucidated by this mechanism. Regarding the sps spectra, three spectral components are assigned and elucidated. Calculated remarkable enhancement in the 3400−3800 cm-1 region for NaI solutions is found to be sensitive to the electric double laye.
