Antecedents of consumer brand loyalty in the Australian wine industry

The wine industry has become fiercely competitive worldwide and as a result, consumers are increasingly exposed to a wider range of wines in retail outlets. This expanding consumer choice means that there is a need for Australian wineries to develop and build consumer loyalty toward their brands. This paper aims to empirically examine the factors influencing consumer loyalty to wine brands. Using data from Australian wine consumers, the authors empirically test a model of antecedents of wine brand loyalty. The model considers wine brand trust, wine brand satisfaction, wine knowledge, and wine experience. Hypotheses were tested with structural equation modeling. The findings of this study show that wine knowledge and wine experience affect wine brand loyalty indirectly through wine brand trust and wine brand satisfaction. In addition, it is demonstrated that consumer satisfaction with a wine brand is the strongest driver of wine brand loyalty. The result of this study has value for Australian wineries, wine retailers, and wine marketers.
Effect of Moisture Conditions in Rice Paddies on Phosphorus Fractionation in Agriculture Soils of Rapidly Developing Regions of China

Moisture conditions in rice paddies play an important role in phosphorus (P) cycling and may affect P loss to nearby water bodies. This study seeks to identify factors that contribute to P-fraction transformations in flooded rice paddies on Cambosols and Anthrosols using Zhangjiagang County of the Yangtze River delta region, China, as a study area. Soil samples preserved under flooded and aerobic conditions (n = 60) were collected, and P fractions and soil properties were measured. Under flooded conditions, soluble and loosely bound P significantly decreased to half of aerobic levels, aluminum/iron-bound P increased by 66%, and organic-bound P decreased by 64%. Soil organic matter, cation exchange capacity, pH, and active iron were well correlated with soil P fractions under both moisture conditions across two soil orders despite a disparity in soil properties. Further research goals that would aid in specific fertilizer recommendations and management strategies are identified.
Fragmentation of a Single Molten Metal Droplet Penetrating Sodium Pool I Copper Droplet and the Relationship with Copper Jet

The progression of hypothetical core disruptive accidents in metallic fuel fast breeder reactors is strongly affected by the fragmentation of molten metallic fuels due to the molten fuel-coolant interaction (FCI). As a basic study of FCI, the present paper focuses on the fragmentation of a single molten copper droplet with mass from 1 to 5 g, whichpenetrated a sodium pool at instantaneous contact interface temperatures (Ti) from 995 to 1,342°C. Intensive fragmentation of a single molten copper droplet was clearly observed even if Ti values are below the melTsing point (1,083°C) of copper besides the higher Ti range. The intensive fragmentation shows that the mass median diameters (Dm) of copper droplets with a fivefold difference in mass or the same mass have little difference, i.e., they are nearly the same. Under the lower Ti condition, the Dm data of droplet fragments of both the same and different masses scatter widely. It is found that the present Dm/D0 data of mass median diameter normalized by the diameter before touching sodium (D0) give a distribution with larger values than those of molten copper jets with large mass from 20 to 300 g under the lower Ti condition, which were previously reported by the authors, because of the limited amount of heat of droplets. The present Dm=D0 data under the higher Ti condition are found to show an effecTive fragmentation compared with those of molten copper jets with a large mass of 4 kg.
Morphological changes in Enterococcus faecium on exposure to Citrus essential oils in vapor phase as determined by TEM, SEM and AFM

The antimicrobial effects of essential oils in vapor phase have been previously reported although the mechanism whereby they bring about their effect continues to be investigated. Morphological changes give some indication of the extent of the damage to cells brought about by exposure to essential oils and may provide a means of substantiating the physiological and biochemical changes that are integral to the antimicrobial effect. In this study, the morphological changes that occur during exposure of Enterococcus faecium to a Citrus essential oil in vapor phase has been investigated using transmission electron microscopy (TEM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). TEM shows membrane damage, vacuole formation and leakage of cytoplasmic material, SEM shows deformation of shape, whereas AFM, which gives the most information, confirms the deformation, which could be seen even after 15 minutes exposure using this method.
Speciation of Heavy Metals in Sediment of Agbabu Bitumen deposit area, Nigeria

Speciation of heavy metals Cu, Cd, Pb, Ni, Zn, Mn, Fe, Cr and Hg was carried out on sediment of Agbabu with a sequential extraction procedure in the dry and rainy seasons of year 2008. Hg was not detected in all the fractions in the two seasons. In the dry season, all the metals were mostly abundant in Fraction-5, however, Cr (30%) and Mn (23.73%) had high abundance in Fraction-1, Zn (30.97%) was high in Fraction-III, Cu (45.14%) and Fe (31.67%) were also high in Fraction-4. In the rainy season, Cr (35.82%) was mostly abundant in Fraction-1, Zn (36.71%) was high in Fraction-3, Cu (29.28%) was high in Fraction-4 and the remaining metals were mostly abundant in Fraction-V. From the results of the two seasons, the metals had high abundance in Fraction-5 indicating firstly, low mobility and bioavailability, secondly, low degree of pollution by the metals considered and thirdly, the origin of the metals in the environment was likely to be lithogenic. The average potential mobility was calculated for the metals in the two seasons and the following decreasing order was obtained: Cr>Zn>Cu>Mn>Fe>Cd>Ni>Pb>Hg. @JASEM J. Appl. Sci. Environ. Manage.

Dehydration processes in the meta-autunite group minerals meta-autunite, metasaléeite, and metatorbernite

Abstract We investigated dehydration processes in uranyl phosphate minerals of the meta-autunite group that consist of uranyl phosphate sheets and interlayer cations, and water molecules. Meta-autunite [Ca(UO2PO4)2⋅6H2O], metasaléeite [Mg(UO2PO4)2⋅8H2O], and metatorbernite [Cu(UO2PO4)2⋅8H2O] were selected for our study. The change in basal spacing between two adjacent uranyl phosphate sheets with temperature was examined by temperature-controlled X-ray diffraction (XRD) analysis from room temperature (RT) to 300 °C to determine structurally distinct, dehydrated phases. Thermogravimetric and differential thermal analyses (TG/DTA) were also performed under conditions similar to those used for the XRD analysis to clarify the hydration states of the dehydrated phases. Retention of the structure of the uranyl phosphate sheets under a high vacuum, equivalent to 300 °C, was confirmed by transmission electron microscopy. Meta-autunite, metasaléeite, and metatorbernite decreased their basal spacings by losing water molecules. Comparison of the TG/DTA and XRD results indicates that the changes in basal spacings of the dehydrated phases with temperature are as follows: 8.32 Å (6 H2O per unit formula) at RT, 7.31 (? H2O) and 6.68 Å (? H2O) at 75 °C, 6.34 Å (2 H2O) at 120°C, and 5.81 Å (1 H2O) at 300°C for meta-autunite; 8.29 (8 H2O) and 7.73 Å (? H2O) at RT, 6.62 Å (probably, 2 H2O) at 40 °C, 6.54 Å (2 H2O) at 160 °C, and 5.52 Å (1 H2O) at 300 °C for metasaléeite; and 8.61 Å (8 H2O) at RT, 8.07 Å (4 H2O) at 100 °C, 6.58 Å (2 H2O) at 200 °C, and 5.60 Å (1 H2O) at 300 °C for metatorbernite. The dehydration processes revealed by XRD and TG/DTA under similar experimental conditions are slightly different from those obtained by previous studies. Our results clearly demonstrate the presence of previously unknown dehydrated phases of the meta-autunite group minerals with basal spacings less than 6Å that may have distinct thermodynamic properties
Synthesis, spectroscopic and X-ray structure analyses of two N-[(3′-aryl) prop-2′-ynyl]-N,N′-1,2-phenylene di-p-tosylamides

Two N-substituted phenylene diamines C27H24N2S3O4 (I) and C29H25N2S2O4Cl (II), acyclic precursors leading to quinoxaline derivatives, have been synthesized, and characterized by spectroscopic and X-ray structural studies. The molecules of compounds (I) and (II) are linked through intermolecular N—H···O and C—H···O hydrogen bonds into centrosymmetric dimers, with characteristic R22(14) and R22(26) rings, which combine to form infinite polymeric chains propagating along the [001] direction. Additional intermolecular C—H···O hydrogen bonds connect the molecules of (I) into two-dimensional sheet of R44(32) rings in the ab-plane and one-dimensional C(7) chain propagating along the [100] direction in (II). The combination of two-dimensional sheets in the ab-plane (in I) and one-dimensional C(7) chains along the [100] direction (in II) with the polymeric chains along the [001] direction generates a three-dimensional supramolecular assembly in (I) and a two-dimensional framework in (II).
Synthesis and characterization of metal complexes of 3-( N -phenyl)-thiourea-pentanone-2

Copper and cobalt complexes derived from 3-(N-phenyl)-thiourea-pentanone-2 were characterized by elemental, XRD, FTIR, UV–Vis, SEM and 1H NMR spectroanalytical studies. The X-ray diffraction studies indicate that 3-(N-phenyl)-thiourea-pentanone-2 and complexes with copper and cobalt are crystalline in nature with simple cubic lattice structure. IR spectroscopic data were used to assign characteristic vibrational frequencies of groups present in these compounds. Scanning electron micrograms were used to assign morphology and particle size.
Interfacial reactions in ultrahigh vacuum deposited Y‐Si multilayer thin films

Interfacial reactions of ultrahigh vacuum deposited Y‐Si multilayer thin films have been studied by both conventional and high‐resolution transmission electron microscopy, Auger electron spectroscopy, and x‐ray diffraction. An amorphous Y‐Si intermixing layer with a composition approximately equal to YSi2 was found to form in multilayer films with a composition ratio of 1Y:2Si at room temperature. Homogenization in atomic composition in the amorphous phase proceeded in samples annealed at 250–350 °C. In samples annealed at 400 °C for 30 min, the amorphous layer was completely transformed to crystalline YSi2. The formation of crystalline Y5Si3 and YSi was detected in as‐deposited samples with concentration ratios 1Y:1Si and 5Y:3Si as well as in samples prepared with excess Y. Y5Si3 was the only silicide phase present in 5Y:3Si films after 400 °C annealing. The results indicated that the phase formation and stability in Y‐Si multilayers depend critically on the composition. Based on the prediction of a grow.
Application of random forest regression to spectral multivariate calibration

The performance of the random forest (RF) algorithm on the spectroscopic data was studied and compared by bootstrap aggregating of classification and regression trees (bagging CART), partial least squares (PLS) and nonlinear support vector machine (SVM) algorithms. The performances of these algorithms were investigated on four real data sets; these data sets were: (1) UV-Visible spectra of two cardiovascular drugs (hydrochlorothiazide and valsartan); (2) visible spectra of copper, cobalt and nickel complexes with 4-(2-pyridylazo) resorcinol (PAR) as chromogenic reagent; (3) near infrared spectra of corn samples, and (4) near infrared diffuse transmission spectra of pharmaceutical tablets. Results indicate that besides its comparable accuracy and mathematical simplicity, it is computationally fast and robust to noise. Therefore, RF is a useful tool for regression studies and has potential for modeling linear and nonlinear multivariate calibration.
Effect of Fuel Nozzle Geometry on the Stability of a Turbulent Jet Methane Flame

The effect of asymmetric fuel nozzles on the stability of turbulent jet methane flame discharging into still air is investigated experimentally. The emphasis of this study is however, more on the flame liftoff height and velocity, as well as reattachment and blowout velocities. Five nozzles; a pipe, a contracted circular, a triangular, a rectangular and a square, which all have an equivalent diameter of approximately 4.50 mm, are tested. The experimental results reveal that asymmetric nozzles reduces the jet flame liftoff height, and hence stabilizes the flame base closer to the nozzle compared with conventional circular nozzles. This finding correlates well with the entrainment rate of the corresponding non-reacting jets. That is, the flame liftoff height decreases as the jet entrainment increases. Furthermore, the asymmetric nozzles are found to significantly influence the blowout, liftoff and reattachment velocities. The blowout is believed to be primarily governed by the far-field local mixing rate.
Computer Simulation of Single Pit Propagation in Stainless Steel under Potentiostatic Control

A model is proposed for the propagation of corrosion pits in stainless steel under potentiostatic conditions. The model is based on the requirement of a near-saturated local chemistry in the pit and uses an equation previously formulated for the anodic dissolution kinetics in this environment, Salt film precipitation, electrolytic migration, and transport outside the pit are each considered explicitly. Numerical simulations of pit growth have reproduced the experimentally observed characteristics of pitting, including development of a pit cover, spontaneous repassivation of metastable pits, increased stability at higher applied potentials, and a tendency for pits to become dish-shaped rather than hemispherical.
Oxidative Coupling of Methane over Na-W-Mn/SiO2 Catalysts at Elevated Pressures

Na-Mn-W/SiO2 catalysts were studied for the oxidative coupling of methane (OCM) in a micro xed bed reactor made of stainless steel reactor at elevated pressures. The eect of operating conditions, such as GHSV, pressure, temperature and CH4/O2 ratio on the catalytic performance of OCM was investigated. The C2+ selectivity of 80.3% was obtained at a CH4 conversion of 16.1% at 750 , 1.5 10 5 h 1 GHSV, and 0.6 MPa. Also, there is a small output of C3 and C4 hydrocarbons in the tail gas. The results show that unfavorable eects due to elevated pressure can be overcome by increasing GHSV, and the OCM reaction is strongly dependent on the operating conditions at elevated pressures, particularly GHSV and the CH4/O2 ratio.
Use of Dielectric Spectroscopy for Determining Quality Attributes of Poultry Meat

Use of dielectric spectroscopy for determining quality attributes of poultry meat was investigated at frequencies between 200 MHz and 20 GHz and temperatures ranging from -16 oC to 70 oC. Dielectric measurements were performed with an open-ended coaxial-line probe and a vector network analyzer. Samples were cut from chicken breast and placed in a temperature-controlled sample holder for the dielectric spectroscopy measurements. Also, for each chicken breast the pH and water holding capacity were measured. The frequency dependence of the dielectric properties of chicken breast indicates that ionic conduction is the dominant mechanism at the lower frequencies and there is a dipolar relaxation at about 10 GHz. Temperature dependence of the dielectric properties of chicken breast reveals a sharp increase of the dielectric constant and dielectric loss factor at 0 oC. This behavior is similar to that of water.
The occurrence of taranakite in the "dry" Cioclovina Cave (Sureanu Mountains, Romania)

This paper documents the chemistry, physical properties, thermal and infrared behavior and unit-cell parameters of taranakite in the "dry" Cioclovina Cave, which is the second documented occurrence of this mineral in Romania. The mineral occurs as earthy white nodules scattered throughout the terra rossa mass. Associated minerals are low (alpha) quartz and scarce illite. Individual crystals do not exceed 7μm in diameter, are roughly hexagonal and tabular on (0001). The indices of refraction are e = 1.508(1) and to = 1.502(1). The measured density [D m = 2.11(1) g/cm 3 agrees well with the calculated value [D x = 2.133 g/cm 3 ]. A wet-chemical analysis yielded (in wt.%): K 2 O = 9.06, Na 2 O = 0.11, (NH 4 ) 2 O = 0.33, MnO = 0.02, MgO = 0.07, CaO = 0.31, Al 2 O 3 = 18.78, Fe 2 O 3 = 0.34, P 2 O 5 = 42.32, H 2 O = 28.30, total 99.64, which leads to the chemical-structural formula: [K 2 . 5 8 1 Na 0 . 0 4 1 (NH 4 ) 0 . 1 6 9 Ca 0 . 0 7 4 Mg 0 . 0 2 3 Mn 0 . 0 0 4 ](Al 4 . 9 4 2 Fe 0 . 0 5 7 )(PO 4 ) 1 . 9 9 (HPO 4 ) 6 . 0 1 18.07H 2 O. The hexagonal cell parameters refined from three sets of X-ray powder data are a = 8.687(9)A, c = 95.69(5)A, V = 6254(16)A 3 , a: c = 0.091:1. Thermal analyses showed that the molecular water is lost in two steps, before 200°C; the dehydration is complete at 365°C. The band multiplicity on the IR-absorption spectrum suggests that the protonated and unprotonated phosphate groups have C 3 and C 3 v punctual symmetries, respectively, whereas the strong imprint of the bands assumed to P-O-H vibrations suggests the local presence of (H 2 PO 4 ) - groups. Taranakite from Cioclovina is authigenic and crystallized through the in situ fixation of the potassium and aluminum ions derived from a clay precursor into a phosphate structure.

How are Biogenic Amines Metabolized by Monoamine Oxidases

Monoamine oxidases (MAOs) are flavoenzymes important in regulating amine neurotransmitter levels and are the central pharmacological targets in treating depression and Parkinson’s disease. On the basis of quantum chemical calculations, we have proposed a new two-step hydride mechanism for the MAO-catalysed oxidative deamination of amines. In the rate-limiting first step, through its N5 atom, the flavin abstracts a hydride anion from the substrate α-carbon atom and forms a strong covalent adduct with the thus created cation. This is followed by flavin N1 deprotonation of the substrate amino group, facilitated with two active-site water molecules, to produce fully reduced flavin, FADH2, and neutral imine. We have demonstrated that our mechanism is in agreement with available experimental data and provided evidence against both traditional polar nucleophilic and single-electron radical pathways. These results provide valuable information for mechanistic studies on other flavoenzymes and for the design of new antidepressants and antiparkinsonian drugs.
Changes in Pasting Behaviour of Rice during Ageing

Abstract Fifteen varieties of rice belonging to six quality types were stored at room temperature for 51 months. Their Brabender viscograms were determined at intervals for several slurry concentrations. The progressive viscogram patterns showed several distinctive features: first, the paste breakdown steadily decreased with time of storage; simultaneously there was a steady increase in setback, in the temperature or heating time at which the peak viscosity (P) appeared, in the minimum value of P at which a breakdown appeared, and in the P value at which the setback became zero. Clearly ageing rendered the rice substance progressively more organized and resistant to swelling and disintegration. Second, the changes were relatively rapid at first, gradually slowing down later, but did not show signs of being halted even after 4 years, suggesting that ageing of rice probably had no definite end-point. Third, despite the ageing changes, rice of different quality types broadly maintained their inter-quality differences throughout the storage period. Fourth, it is remarkable that the cold-paste:hot-paste viscosity ratio in the samples remained virtually unchanged throughout even while all other viscogram indices changed with storage time. Considering the viscographic technique, the results confirmed that (i) the fixed-P system is far superior to the fixed-concentration one and (ii) breakdown is the primary viscogram index.
Dielectric Constant and Stability of Fluorine‐Doped Plasma Enhanced Chemical Vapor Deposited SiO2 Thin Films

As device geometry shrinks to 0.35 μm and below, the parasitic capacitance between closely spaced metal lines becomes important in terms of resistance-capacitance time delay in device switching. In this study, we investigated the use of fluorine doped plasma enhanced chemical vapor deposition grown silicon oxide thin film as a low dielectric constant intermetal dielectric material. We evaluated C 2 F 6 and an organometallic liquid source triethoxyfluorosilane as the F dopant. It was found that the dielectric constant generally decreased as the F concentration increased. However, we also found that above a certain F concentration, the F-doped oxide film would become unstable and absorb moisture from the ambient. At similar F concentrations, the films deposited with the liquid source are always more stable than those deposited with C 2 F 6 . This, in addition to the different stress vs. low frequency radio frequency power behavior between the two types of film, suggests that the already present Si-F bond in the liquid precursor results in a denser and more stable film compared to the C 2 F 6 doped film where interstitial F may be present.
