Improvement of the Wettability Properties of Compost Using Seaweed

ABSTRACT. Composting substrate components from a wide variety of organic materials are becoming more prevalent in ornamental growing medium mixes. Hazelnut husk (HH) and seaweed (HHSW) composts were investigated for their different hydro-physical roles in substrate dynamics. The water repellent material HH was composted either solely or mixed with seaweed (1:1 by volume) and the hydro-physical properties related to the water retention and wettability of the two composts were evaluated using the water drop penetration (WDPT) and molarity of ethanol droplet (MED) tests and contact angle (θ) determination. The addition of seaweed to the HH compost mixture had positive effects on the water holding capacity, water conductivity, air porosity, and wettability characteristics compared to pure HH compost. Although both composts exhibited signs of hydrophobicity under dry conditions, the repellency rate was more severe in the pure HH compost. The wettability tests results indicate that seaweed improved the hydrophobicity of HH compost by at least two ranking classes, from severe hydrophobicity to moderate hydrophobicity. Also, the contact angle reduced from 107° to 103° by composting seaweed. Seaweed was found to have an influence on the hydrological properties when incorporated as a compost component with the HH substrate.
The role of taxpayers’ education in mediating the relationship between tax sanctions and taxpayers’ motivations to use e-filling

This study aimed to test empirically the effect of tax-payers educational status to the corerelation between the taxpayers’ perceptions about tax sanctions and taxpayers’ willingness in reporting tax using e-Filling. This study used tax-payers educational status as moderated variable, taxpayers’ perceptions about tax sanctions as independent variable, and taxpayers’ willingness in reporting tax using e-Filling as dependent variable. This study used primary data that are collected by using questionnaire with incidental random sampling as the sampling technique. The sample of the research is the taxpayers domiciled in South and East Denpasar. Since South and East of Denpasar are the service area of KPP Pratama East Denpasar. The sample of this research were 100 people. The data analysis of this research used Statistical Analysis Method by using Moderated Reggresion Analysis. The results of the research show that the taxpayers perception about tax sanctions has significantly positive effect against the taxpayers willingness in reporting tax using e-Filing and the level of taxpayers educational status has significantly negative effect to the relationship between taxpayers’ perceptions about tax sanctions and taxpayers’ willingness in reporting tax using e-Filling. Keywords: Educational Status, Tax Sanctions, e-Filling

Defect Chemistry of Donor‐Doped and Undoped Strontium Titanate Ceramics between 1000° and 1400°C

The electrical conductivity, sigma, of donor-doped and undoped strontium titanate (SrTiO3) ceramics and, in some cases, single crystals, Sr1-xLaxTiO3 (0 ≤ to x ≤ 0.1), was investigated in the temperature range of 1000°-1400°C under oxygen partial pressures, PO2, of 10-20-1 bar. In conjunction with Hall data and thermopower data from related papers, a set of constants for a defect-chemical model was determined, precisely describing point-defect concentrations and transport properties of these materials. In contrast to former works, temperature-dependent transport parameters and their non-negligible influence on the determination of the constants was considered, as well as the equilibrium restoration phenomena of the cation sublattice, which can be studied only at such high temperatures. It was shown that defects in the cation sublattice completely govern the electrical behavior of donor-doped and undoped SrTiO3. In the latter case, frozen-in strontium vacancies act as intrinsic acceptors, determining the sigma(PO2) curves at lower temperatures. This intrinsic acceptor concentration also can be calculated with this model. The very good agreement between calculation and measurement is shown in many examples.
Transition states, trapped trajectories, and classical bound states embedded in the continuum

We show that the best choice of transition state, for the atom exchange reaction in a classical collinear collision of an atom with a diatomic, is a classical bound state embedded in the continuum: a periodic vibration of the triatomic system across the interaction region of the potential surface. These unstable bound states also serve as limit sets of the trapped trajectories that form the boundary of reactivity bands in molecular collisions, and we comment on the implications of this result for calculation of product state distributions. Numerical calculations of transition states are presented for the collinear H+H2 and F+H2 reactions.
The Relationship between Purity Culture and Rape Myth Acceptance

The current study investigated the relationship between purity culture, rape myth acceptance, and intrinsic religiosity in the Christian population. Specifically, this study explored if purity culture endorsement would be associated with increased rape myth acceptance and increased likelihood of incorrectly labeling rape. It was also examined whether intrinsic religiosity would ameliorate the relationship between purity culture and rape myth acceptance. Ninety-nine Christian men and women participated in this study. Results demonstrated that endorsement of purity culture was related to increased endorsement of rape myths and increased likelihood of labeling marital rape and acquaintance rape as consensual sex. Intrinsic religiosity was also found to be a significant moderator of the relationship between purity culture and rape myth acceptance. Overall, these findings have important implications for how purity culture is taught and understood, and how these teachings relate to the Christian population’s involvement in the cultural dialogue surrounding sexual assault.
Simultaneous determination and pharmacokinetic study of P-hydroxybenzaldehyde, 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucoside, emodin-8-O-β-D-glucopyranoside, and emodin in rat plasma by liquid chromatography tandem mass spectrometry after oral administration of Polygonum multiflorum

A rapid and specific liquid chromatography tandem mass spectrometry (LC-MS/MS) method was developed for the simultaneous analysis of P-hydroxybenzaldehyde, 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucoside, emodin-8-O-β-D-glucopyranoside, and emodin in rat plasma, and it was applied to the pharmacokinetics (PK) studies of the four compounds from the herb Polygonum multiflorum. The analysis was carried out on a Phenomenex Hydro-RP C18 (150 × 2.0 mm, 4 μm) reversed-phase column by gradient elution with a flow rate of 0.4 mL min−1. All of the analytes including internal standards (I.S.) were monitored by selected reaction monitoring with an electrospray ionization source. Linear responses were obtained for P-hydroxybenzaldehyde, 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucoside, emodin-8-O-β-D-glucopyranoside, and emodin ranging from 1 to 1000 ng mL−1. The intra-day and inter-day precisions (RSD) were less than 8.61% and 8.75%, respectively. The extraction recovery ranged from 77.00 ± 5.54 to 91.30 ± 2.96, and the I.S. was 85.82 ± 3.58%. Stability studies showed that the accuracies of P-hydroxybenzaldehyde, 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucoside, emodin-8-O-β-D-glucopyranoside, and emodin ranged from 94.66 ± 3.54 to 106.84 ± 6.91; the matrix effects ranged from 92.14 ± 3.63 to 103.98 ± 8.71. The validated method was successfully used to determine the concentration–time profiles of P-hydroxybenzaldehyde, 2,3,5,4′-tetrahydroxystilbene-2-O-β-glucoside, emodin-8-O-β-D-glucopyranoside, and emodin.

Treatment of fishery washing water by ultrafiltration

The recovery and concentration of proteins from the waste water of a fish plant was achieved by ultrafiltration. Two UF modules equipped with Ceraver and Patterson Candy International (PCI) membranes were tested. Despite different cut-off values, similar apparent rejection coefficients (70% and 80% respectively) were obtained. Optimum economic conditions were established, corresponding to average transmembrane pressures of 2.2 x10 5 and 3.8 x 10 5 Pa and tangential flow rates of 6.0 and 0.47 m s -1 for Ceraver and PCI membranes, respectively. The protein concentration in the feed solution was increased from 5 to 35 g dm -3 . The study showed that the method could reduce pollution due to organic matter by decreasing the value of the Biological Oxygen Demand after 5 days (BOD 5 ) by about 80%.
Expressions of microRNA-29a and microRNA-34a in pleomorphic adenomas of salivary glands.

Background The most common type of salivary gland tumor is pleomorphic adenoma. The genetic area of focus in the diagnosis of salivary gland tumors is a study of the role of miRNA. Methods Twenty-two patients with pleomorphic adenomas of the salivary glands were used for the examinations. The histological typing of the salivary gland tumors was performed when using routine staining with hematoxylin and eosin, as well as with immunohistochemistry. The expressions of miR-34a and miR-29a were evaluated by using reverse transcription and the quantitative polymerase chain reaction in a real-time setting. In addition, the study also calculated the levels of expression of miR-29a and miR-34a in the venous blood. Results The majority of patients-15 (68.18%) and 22 (100.00%) had a positive response to human papillomavirus (HPV) and pleomorphic adenoma gene 1 (PLAG1), respectively. The conducted analyses of the expressions of miR-34a and miR-29a showed that the highest expression was observed in the salivary gland tissue adjacent to the tumor (1,052.02±367.20 and 111.93±56.97, versus 47.72±28.93 and 8.12±4.40 in the intact salivary gland tissue, respectively). Conclusions There was a sufficiently high level of miR-34a and miR-29a expressions in the tissues of the tumor of pleomorphic adenomas of the salivary glands when compared with the intact salivary gland tissue.
Model for Melting‐Curve Maxima at High Pressure

A two‐species model for the liquid proposed by Klement in order to account for the existence of high‐pressure melting‐curve maxima is further examined from the point of view of the theory of regular solutions. Equations for the concentration of the two species as a function of pressure and temperature are derived. A survey of structural data on liquids provides positive evidence for the existence of two species in the melts of some pure substances.
Flame structure and NO emissions in gas combustion of low calorific heating value

Numerical study on addition effects of CO and CO2 in fuel side (H2/Ar) on flame structure and NO emission behaviour in counterflow diffusion flame has been conducted with detailed chemistry to fundamentally understand gas combustion of low calorific heating value. A modified Miller–Bowman reaction scheme including a complementary C2‐reaction subset is adopted. The radiative heat loss term, which is based on an optically thin model and it especially important at low strain rates, is included to cover the importance of the temperature dependence on NO emission. Special interest is taken to estimate the roles of added CO and CO2 in fuel side on flame structure and NO emission characteristics. Increasing CO concentration in fuel side contributes to the enhancement of combustion due to the increase effect of the concentration of reactive species. The increase of added CO2 concentration in fuel side suppresses overall reaction rate due to the high heat capacity. It is seen that chemical effects due to the breakdown of added CO2 in fuel side make C2‐branch chemical species be remarkably formed and the prevailing contribution of prompt NO is a direct outcome of these effects. It is found that in the combined forms of H2/CO/CO2/Ar fuels the effects of added CO and CO2 concentrations in fuel side compete contrarily to each other in NO emission behaviour. Particularly the role of added CO is stressed in the side of restraining prompt NO. Copyright © 2003 John Wiley & Sons, Ltd.
Interfacial supercooling and the precipitation of hydrohalite in frozen NaCl solutions by X-ray absorption spectroscopy

Laboratory experiments are presented on the phase change at the surface of sodium chloride – water mixtures at 14 temperatures between 259 K and 240 K. Chloride is a ubiquitous component of polar coastal surface snow. The chloride 15 embedded in snow is involved in reactions that modify the chemical composition of snow as well as ultimately impact the 16 budget of trace gases and the oxidative capacity of the overlying atmosphere. Multiphase reactions at the snow – air interface 17 have found particular interest in atmospheric science. Undoubtedly, chemical reactions proceed faster in liquids than in solids; 18 but it is currently unclear when such phase changes occur at the interface of snow with air. In the experiments reported here, 19 a high selectivity to the upper few nanometres of the frozen solution – air interface is achieved by using electron yield near20 edge X-ray absorption fine structure (NEXAFS) spectroscopy. We find that sodium chloride at the interface of frozen solutions, 21 which mimic sea-salt deposits in snow, remain as supercooled liquid down to 240 K. Below this temperature, hydrohalite 22 exclusively precipitates, anhydrous sodium chloride is not detected. In this work, we present the first NEXAFS spectrum of 23 hydrohalite. The hydrohalite is found to be stable while increasing the temperature towards the eutectic temperature of 253 K. 24 Taken together, this study reveals no differences in the phase changes of sodium chloride at the interface as compared to the 25 bulk. That sodium chloride remains liquid at the interface upon cooling down to 240 K, which spans the most common 26 temperature range in Polar marine environments, has consequences for interfacial chemistry involving chlorine as well as for 27 any other reactant for which the sodium chloride provides a liquid reservoir at the interface of environmental snow. 28 Implications for the role of surface snow on atmospheric chemistry are discussed. 29 30 https://doi.org/10.5194/tc-2020-253 Preprint.

Qualitative and quantitative analysis of gallic acid in Alchemilla vulgaris, Allium ursinum, Acorus calamus and Solidago virga-aurea by chip-electrospray ionization mass spectrometry and high performance liquid chromatography

AbstractThis study presents the results obtained from qualitative and quantitative analysis of gallic acid from hydro-alcoholic extracts (methanol, ethanol) of plants from Plantae regnum. Plant qualitative analysis was performed using a novel mass spectrometric (MS) method based on fully automated chip-nanoelectrospray ionization (nanoESI) high capacity ion trap (HCT) while quantitative analysis was carried out by high performance liquid chromatography (HPLC). These methods were applied to Alchemilla vulgaris — common lady’s-mantle (aerial part), Allium ursinum — bear’s garlic (leaves), Acorus calamus — common sweet flag (roots), Solidago virga-aurea — goldenrod (aerial part). Obtained results indicated that methanol extracts (96%, 80%) have a gallic acid content ranging between 0.0011–0.0576 mg mL−1 extract while the ethanol extracts (96%, 60%) exhibit a gallic acid concentration that varies between 0.0010–0.0182 mg mL−1 extract.
Annular dynamical disorder of the rare earth ions in a La2Zr2O7 pyrochlore via single crystal synchrotron X-ray diffraction

Abstract The reciprocal lattices of a range of rare earth titanate and zirconate pyrochlores have recently been shown to exhibit an extremely characteristic diffuse intensity distribution identical in form to that characteristic of β-cristobalite implying the existence of β-cristobalite-like orientational disorder of essentially rigid, (O2)(R3+)4 tetrahedra within the pyrochlore structure type. A single crystal X-ray diffraction study of La2Zr2O7 has been carried out utilizing synchrotron radiation in order to investigate this proposed orientational disorder and to determine an unknown oxygen atom fractional co-ordinate. An annular distribution of residual electron density is found around the average La ion positions in {111} planes perpendicular to the local O2–La–O2 directions and interpreted as implying that the La ions never in fact occupy the average 16d positions but rather are dynamically disordered around an annulus perpendicular to that direction in an exactly analogous manner to that which occurs in β-cristobalite.
Benefits of the Adaptive Algorithm for Retracking Altimeter Nadir Echoes: Results From Simulations and CFOSAT/SWIM Observations

The accuracy of sea surface parameters retrieved from altimeter missions is predominantly governed by the choice of the so-called “retracking” algorithm, i.e., the model and inversion method implemented to obtain the surface parameters from the backscattered waveform. For continuity reasons, the choice of space agencies is usually to apply the same retracker from one satellite mission to the other to ensure long-time homogeneous series. In this article, taking the opportunity of a new configuration of the nadir pointing measurements onboard the recently launched China France Oceanography Satellite (CFOSAT) with the Surface Waves Investigation and Monitoring (SWIM) instrument (Hauser et al., 2020), the retracking method was upgraded, by implementing a novel algorithm, called “Adaptive” retracker. It combines the improvements brought by Poisson et al., (2018) for the estimation of surface parameters from peaked waveforms over sea ice, improvements in the way the instrumental characteristics are considered in the model (mispointing, point target response) and a more accurate consideration of speckle statistics. In this article, we first show from simulations carried out in the instrumental configuration of SWIM that the Adaptive algorithm has better accuracy and performance than the classical MLE4 algorithm. Then, the geophysical parameters obtained with real data from SWIM are analyzed with comparisons to reference data sets (model and products from altimeters). We show that this new algorithm has several benefits with respect to the classical MLE4 method: no need of lookup tables to correct biases, significant noise reduction on all geophysical variables especially the significant wave height, and performance of inversion over a large set of echo shapes, resulting from standard oceanic scenes as well as highly specular conditions such as over bloom or sea ice.
Game fish response to dredging of a eutrophic urban lake in Minnesota

Abstract Mundahl ND, Hoisington J. 2020. Game fish response to dredging of a eutrophic urban lake in Minnesota. Lake Reserv Manage. 37:170–185. We compared relative abundances, average weights, and growth rates of 6 game fish species before and after the 1999–2001 partial dredging of Lake Winona, a eutrophic, urban lake in Minnesota, to determine whether lake dredging sustainably changed fish population structure to the benefit of anglers. Relative catch rates (trap nets, gill nets, electrofishing) and growth rates were obtained from various fish population assessments and lake surveys conducted by the Minnesota Department of Natural Resources (MN DNR) from 1980 to 2016 for both Lake Winona and Lake Oscar, an ecologically similar lake that has not been dredged. Before-after control-impact (BACI) analyses revealed that compared to Lake Oscar, relative catch rates in Lake Winona after dredging declined significantly for bluegill (Lepomis macrochirus), black crappie (Pomoxis nigromaculatus), and northern pike (Esox lucius), and increased significantly for walleye (Sander vitreus) and largemouth bass (Micropterus salmoides). Average weights of yellow perch (Perca flavescens) and pike increased significantly after dredging. Only black crappie displayed improved growth after dredging. Largemouth bass catch rates for quality- and preferred-size fish increased in postdredging surveys. Although predredging data are lacking, population size structures and relative weights of bluegill, crappie, and bass post dredging were within ranges that meet MN DNR management objectives. Overall, dredging of Lake Winona was followed by improved quality and structure of game fish populations in this system, something that decades of previous biomanipulation and macrophyte management had not accomplished.
