High-temperature phase transitions in tungsten trioxide - the last word?

The structures of tungsten trioxide, WO3, have been studied in fine temperature steps, from room temperature to 1000 °C, by means of very high-resolution neutron powder diffraction. It was confirmed that the sample used was single-phase monoclinic in space group P21/n at room temperature. In addition to this monoclinic structure, the structures observed were an orthorhombic structure in Pbcn from about 350 to 720 °C, another monoclinic structure in P21/c from about 720 to 800 °C, a tetragonal structure in space group P4/ncc from 800 to 900 °C, and above 900 °C a second tetragonal structure in P4/nmm. The transformation from the Pbcn orthorhombic to the P21/c monoclinic structure was certainly discontinuous, and indeed just above 720 °C two-phase mixtures were observed. The other transitions were continuous or nearly so, all three being apparently tricritical in nature. The sequence of phases, and nature (continuous or otherwise) of the transitions between them, can be well understood by reference to the results from a group theoretical analysis.
Big Data Approach to Realised Volatility Forecasting Using HAR Model Augmented With Limit Order Book and News

The study determines if information extracted from a big data set that includes limit order book (LOB) and Dow Jones corporate news can help to improve realised volatility forecasting for 23 NASDAQ tickers over the sample from 28 June 2007 to 17 November 2016. The out-of-sample forecasting results indicate that CHAR model outperformed all other models in the HAR-family of models, and there is strong evidence that news and LOB data provide statistically significant improvement in RV forecasts. Specifically, the slope of the bid-side of LOB has better predictive power than the slope from the ask-side. For normal volatility day, the ‘negative’ sentiment derived from the news has a clear impact, while ‘news count’, and to a lesser extent, ‘weak modal’, and ‘uncertainty’ can help to forecast volatility jumps. The depth of the LOB also helps to forecast volatility jumps. Indeed, the findings also suggest normal volatility and volatility jumps should be separately analysed as variables improve the forecasting performance of normal days causes a degradation in the forecasting performance of volatility jumps and vice versa. On the other hand, increasing the estimation sample size causes statistically signiﬁcant degradation in the forecasting performance of volatility on normal days, especially if it includes extreme volatility period such as the 2008 financial crisis, but a longer sample improves the forecast of volatility jumps.
IMPACT OF MANURE APPLICATION ON SOIL PHOSPHORUS SORPTION CHARACTERISTICS AND SUBSEQUENT WATER QUALITY IMPLICATIONS

For nutrient management purposes, it is important to understand the impact of manure application on soil phosphorus (P) sorption characteristics and what it means with regard to potential environmental problems. The objectives of this study were (i) to determine whether previous manure applications impact P sorption capacity and strength; (ii) to characterize the relationship between water soluble-P (WSP) and degree of P saturation (DPS); and (iii) to characterize the relationship between WSP and P sorption capacity and strength. Phosphorus sorption isotherms were constructed for seven pairs of soils with and without a history of manure application. Within a soil series, P sorption isotherms were compared to determine the effects of manure application. Manure application increased sorption capacity significantly in the Nicollet soil series. Phosphorus sorption capacity was unchanged by manure application in the Waukegan soil series. Manure application reduced P sorption capacity in the Port Byron, Sanburn, Verndale, Ves, and Barnes soils. Phosphorus sorption strength decreased in five of the seven soil series after manure application. The degree of P saturation and soil test P were strongly linearly correlated to WSP. Water soluble-P was less than 1 mg L−1 when DPS was less than 21.7%. When manure application increased DPS to more than 26%, sorption strength was reduced; P was bound less tightly to the soil on low strength sorption sites, such that P was more readily available. Sorption strength was used to determine the soil test P level above which there is increased risk to water quality because of reduced sorption strength and subsequent increases in WSP; this occurred when Bray-P was greater than 60 mg kg−1. Phosphorus sorption strength seems to be the sorption property that is most sensitive to applications of P.
Effects of Strain and Skip-a-day Feed Restriction on Carcass Characteristics of Broiler Chickens at Finisher Stage

The present study was undertaken to investigate the effects of strain and feed restriction on live weight and carcass characteristics of broiler chickens. Feed restriction is a management tool designed to reduce the amount of feed consumed by broilers to produce more meat without jeopardizing their health condition. The strains of broilers reared are Arbor Acre, Hubbard and Marshall. The four treatments are: Afull feeding (control), B-5 th week feed restricted, C6 th week feed restricted and D7 th week feed restricted groups. After each feed restriction regime the birds were restored to full feeding until the termination of the experiment on the 56 th day. Analyzed results showed that there was no significant (p>0.05) effect of strain on live weight, bled weight, dressed weight, eviscerated weight, breast weight, back weight, thigh, drumstick, wing weight, head, heart, liver, proventriculus, intestine weight, spleen, lung + trachea, vent and shank. Arbor Acre, Hubbard and Marshal strains of broiler recorded similar mean values regardless of the treatment imposed on them. Therefore, any of the strains of broiler chickens can be reared for meat production and revenue generation. In addition, there was significant (p<0.01) effect of feed restriction regimes on live weight of broiler chickens and carcass traits except back, thigh and wing muscle weights. The 5 th week restricted birds recorded superior mean values than 6 th and 7 th week restricted birds in some of the traits measured. It is therefore suggested that feed restriction be carried out at younger age, say 5 th week, for farmers to derive maximum benefits from the concept. Any other time during finisher stage may be counterproductive.
Immobilization of Lead with Nanocrystalline Carbonated Apatite Present in Fish Bone

Reactions of lead with phosphate can immobilize lead in situ in contaminated soils. We investigated reactions between dissolved lead and fish bones, which are an environmentally useful phosphate source for lead immobilization. Fish bones contain biogenic nanocrystalline apatite [Ca5(PO4)3OH(s)] that is carbonated and hydroxyl-deficient. Experiments compared the lead removal upon reaction with unheated fish bones, fish bones that had been heated to char the organic phase, and a synthetic hydroxylapatite solid. The investigation combined analyses of the aqueous phase with direct characterization of the solid phase by laser Raman microprobe spectroscopy to determine the identity and location of any lead phosphate precipitates. Dissolved lead concentrations decreased by several orders of magnitude after reaction with all of the solid phosphates studied. The immobilization of lead had a slight but measurable effect on the continuing release of calcium and phosphate from the solid phase to solution. The fish bo.
A New Observation on the Phase Transformation of TiO2 Nanoparticles Produced by a CVD Method

Titania (TiO2) nanoparticles with primary diameters of less than 30 nm were produced by the thermal decomposition of TTIP and by the oxidation of TiCl4 in a cylindrical furnace reactor at 1200°C. Particle size, crystalline phase, and phase transformation were investigated as a function of precursor concentration and total flow rate by TEM, a DMA/CNC system, XRD, and TG-DTA. The results show that both particle size and number concentration were increased with increasing precursor concentration, and that the primary size could be controlled by changing the operating conditions. An anatase-to-rutile phase transformation occurred at TTIP concentrations above 7.68 × 10−6 mol/l and this was enhanced with increasing precursor concentration. It is noteworthy that the transformation is independent of grain size but appears to be related to the presence of carbon impurities in the nanoparticles.
High Temperature Spouted Bed Paddy Drying with Varied Downcomer Air Flows and Moisture Contents: Effects on Drying Kinetics, Critical Moisture Content, and Milling Quality

Abstract This research is an experimental study on paddy drying conducted in a two-dimensional spouted bed batch dryer to investigate the effects of downcomer airflow, drying temperature, and initial moisture content on drying kinetics, milling quality, and thermal energy consumption. The system of spouted bed drying and a comparison of spouted bed drying in the present study, and fluidized bed drying in the related literature, are also discussed. Downcomer air flows of 0, 20, and 30% ([defined as mass flow rate of downcomer air/total mass flow rate of air] × 100%), inlet air temperatures of 110, 130, and 150°C, and initial moisture contents of 18–35% d.b. were used. It was found that moisture transfer did not only occur in the spout region but also took place in the downcomer region. The moisture content and temperature of the paddy dropped as grain moved downward in the downcomer, which resulted from the presence of an evaporative cooling phenomenon. The characterization of drying curves regardless of any drying condition could be described by nearly linear relationships between moisture content and time. Although high downcomer air flow and drying temperature could enhance effective moisture reduction, they caused an adverse decrease in critical moisture content and HRY (head rice yield). Critical moisture content and HRY could also increase with an increase in initial moisture content. The difference in moisture content between the initial and critical moisture contents varied between 4.5 and 8.0%d.b. , depending upon drying conditions. No significant effect on color was evident. From the point of view of HRY, the correct management of a two-stage spouted bed drying system could be a suitable and attractive alternative for rice mills. Finally, a comparison between the spouted bed drying and fluidized bed drying showed that the spouted bed had advantages over the fluidized bed in terms of product quality. The specific drying rates (kg water evaporated h−1 m−3) of both techniques were comparable. With respect to energy consumption, spouted bed drying was not as efficient as fluidized bed drying for intermediate initial moisture content, but a contrary result was obtained for low initial moisture content.
Coins for Bombs: Increased Transparency of the Global Financial System - Evidence from Terrorist Attacks Financing Detection in Blockchain-based Currencies

The proliferation of blockchain-based cryptocurrencies, which essentially use public accounting ledgers, has two opposing effects related to the global financial system's transparency. On the one hand, governments, market regulators, and financial institutions make significant efforts to curtail the financing of illicit activities that cryptocurrencies may be able to circumvent. On the other hand, funds and transfers that used to be known only by the involved parties are now transparent to anyone with knowledge of blockchain and accounting. This study empirically examines whether it is possible for outsiders to identify evidence of financing international terrorist attacks on public blockchain systems. We do so by utilizing empirical strategies based on accounting and finance literature, forensic accounting, and machine learning algorithms on millions of cryptocurrencies' transfers. We provide evidence that blockchain-based cryptocurrencies are used to finance terrorist attacks. However, the blockchain ledger underlying transparency also enables outsiders to identify the fund trails and predict terrorist attacks. <br>
Pengaruh Disiplin Kerja Terhadap Kinerja Karyawan Dengan Lingkungan Kerja Sebagai Variabel Moderasi

This study aims to analyze the effect of work discipline on employee performance with the Work Environment as a Moderation Variable. At one of the private universities in Semarang. The sample is all members of the population using a saturated sampling method. The analytical tool used in this research is Moderation Regression Analysis. Hypothesis 1 testing shows that the value of t count = 2.745> t table = 1.645 with a significance number = 0.005 < = 0.05 (significant). So (H1) which states that work discipline has a positive effect on employee performance is proven. Regression coefficient β1 = 0.257 (positive sign), this can be interpreted that the higher the work discipline, the higher the employee performance. Hypothesis testing 2. Testing (H2) shows that the t value of the influence of the moderating variable is 2.599> t table = 1.645 with a significance number = 0.016 < = 0.05 (significant). (H2) which states that the Work Environment positively moderates the effect of Work Discipline on Employee Performance. The interaction test shows β2 = 0.175 (positive sign), this can be interpreted that a good work environment will strengthen the effect of work discipline on employee work discipline. Keywords: work discipline, Employee performance, Work environment
Polyethersulfone-Activated Carbon Hybrid Particles for Phenobarbital Removal

Polyethersulfone-Activated carbon (PES-AC) hybrid particles are prepared using a liquid-liquid phase separation technique. The PES-AC hybrid particles are then used for the removal of phenobarbital (PB) from its aqueous solutions. The adsorption ability of the particles increased significantly when activated carbon was embedded into the particles, and with the increase of the activated carbon content in the hybrid particles, the PB adsorbed amount increased. Also when the PB concentration increased, the adsorbed amount increased. The adsorption of PB to the hybrid particles belongs to the Freundlich adsorption. To more effectively remove PB, PES-AC particle columns were prepared; and the particle column showed more high removal efficiency for PB. The results suggested that the PES -AC hybrid particles have a potential to be used for the removal of PB, and may be used in blood purification.
The influence of surfactants to the stability of coal water suspension

In this work a coal-water suspension with containing of 30% (mass) coal was investigated. Obtained coal-water suspension was stabilized by sodium dodecyl sulphate (SDS) and oxyethylated alkyl phenol (ОP-10). A wettability isotherm of coal surface by surfactants, optimal regime of coal dispersion, adsorption isotherm, viscosity, fluidity and heat of combustion of 30% (mass) coal-water suspension were determined. Obtained results allow to recommend 30% coal-water suspension stabilized by surfactants as a fuel.
The effect of size, sex and season on the accumulation of heavy metals in perch (perca fluviatilis L., pisces: Cyprinidae) in lake Koronia (Macedonia, Greece)

The concentrations of Cd, Cr, Cu, Fe, Pb and Zn were determined in whole perch (Perca fluviatilis, L.) from lake Koronia (Greece). The mean concentrations of Cd, Pb and Zn were all significantly higher (P 0.05) with sex. All metal concentrations were negatively correlated (P < 0.05) with fish body weight whereas concentrations of Cr, Cu, Fe and Zn were negatively correlated (P < 0.05) with total length. Binary intermetallic relationships showed significant correlations (P < 0.007) between the most metals examined. Principal components analysis revealed that there was a relationship between metal concentrations and the different sources of metal contamination. In general, all metals displayed minimum concentrations in May and maximum ones in winter and early spring.
Disease model identification methods based on maximum test and performance analysis

Combinatorial explosion and computational burden are always the challenges for genome-wide association study. In order to reduce the computation cost, many multi-stage methods were put forward to identify the disease models. However, one-way and two-way disease models always can be detected to leave out some SNPs for non-significance. And these SNPs are combined with other SNPs to get higher disease models. In this paper, three test statistics, Max Gtest, Max Entropy Difference and Max Relative Entropy, had been presented for the first stage to detection disease models with main effect and without main effect. Five testing methods were used for examining multiply simulation datasets and real dataset. Results were revealed that Max Entropy Difference test is the best method of recognition in five filtering methods with main-effect and max-statistic test is just right method to identify model without main-effect. Results also were showed that five statistics can get interest power for two-ways on simulation datasets and real dataset. We believe that these statistics can find strong and weak SNPs for next step in computationally and statistically.
Phenomenology of childhood hoarding

Abstract Hoarding disorder (HD) has been recently added as a separate diagnostic category in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. HD is a common and disabling disorder, with an estimated prevalence in the general population of 2–6%. Although evidence suggests that the onset of hoarding symptoms is usually during childhood and adolescence (youth), relatively little is known about HD in this population. The present article is a selective review of emerging literature on the clinical features of hoarding in youth.
Month-End Reporting, Cash-Flow News, and Asset Pricing

We show that the stock market regularly and systematically receives information about company fundamentals through month-end reporting, even before the quarterly earnings announcement. Such cash-flow news concentrates at the beginning of a month and affects company announcements, analyst revisions, and stock returns. Using this time variation in cash-flow news, we show evidence supporting cash-flow news being more persistent than discount-rate news. Individual stock returns exhibit a post-monthly-announcement drift. Time series market momentum exists only when conditioning on past first-half month return, and is stronger when the past market-wide earnings surprise is bigger.
Optimal Control Approach For HIV-1 Infection in CD4+T Cells with RTI and PI Treatments

The purpose of this paper is to expose the optimal approach of controlling HIV-1 infection in CD4+T cells with Reverse Transcriptease Inhibitors (RTI) and Protease Inhibitors (PI) treatments. The scope of the paper includes a proposed model of the dynamic system of HIV-1 infection in CD4 cells with RTI and PI as controls and a proposed objective function model that minimizes infected CD4+T Cells, the population of free virus and therapeutic costs. From the dynamics system model and objective function model, we designed an optimal control for HIV-1 infection control. In this paper, we obtained optimal control for RTI and PI therapies. The results of this paper are as follows: by using the optimal control approach, we obtained infectious control strategy that minimizes actively infected CD4+T Cells, the population of free virus and the cost of treatment. In other words, optimal control is a good approach in determining infection control strategies that minimizes the objective function.
Impact of Masculinity and Normative Male Alexithymia on Interpersonal Difficulties in Young Adult Males

The study of psychology of men and masculinity received scientific attention recently focusing on gender differences and its impact in communicating and expressing emotions. It has been proposed that men, who had been discouraged as boys in expressing and talking about their emotions showed difficulty in identifying and expressing emotions throughout their lives which has been termed as normative male alexithymia (Levant, 2011). Emotions are related to many vital functions, and its awareness leads to healthy intrapersonal and interpersonal functioning. The present study aimed to explore the impact of masculinity and normative male alexithymia on interpersonal difficulties in young adult males. Assessment measures included a demographic form, sex role attitude scale, normative male alexithymia scale, and interpersonal difficulties scale. Sample of the study (N=232) included young adult males (Age = 18 to 24) who were approached through the universities of Lahore. Results suggested that with the increase in traditional masculinity, normative male alexithymia and interpersonal difficulties also increases. Further it was found that traditional masculinity predicted interpersonal difficulties and normative male alexithymia aggravate the relationship. Moreover, normative male alexithymia mediates the relationship between traditional masculinity and interpersonal difficulties. Findings of the study were explained and future implications were discussed.
Modeling and Optimization of Mechanical Properties of PA6/NBR/Graphene Nanocomposite Using Central Composite Design

Thermoplastic elastomer of PA6/NBR reinforced by various nanoparticles have wide application in many industries. The properties of these materials depend on PA6, NBR, and nanoparticle amount and characteristics. In this study, the simultaneous effect of NBR and graphene nanoparticle content on mechanical, thermal properties, and morphology of PA6/NBR/Graphene nanocomposites investigated by Central Composite Design (CCD). Thermal properties and morphology of PA6/NBR/Graphene nanocomposites were investigated by Differential Scanning Calorimetry (DSC), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The results indicate that a small percentage of error between predicted values of mechanical properties and experimental values was achieved. An increase in graphene content have a positive impact on the tensile strength but increasing the NBR phase has the opposite effect. A maximum tensile strength of 35.3 MPa for PA6/NBR/Graphene nanocomposites was obtained at the NBR and graphene content of 20 %wt and 1.5 %wt, respectively. The thermal behavior of the PA6/NBR blend improved with addition graphene. With the addition of 1.5 % graphene content to PA6/NBR blend, the crystallization temperature and melting temperature increased from 192.1 to 196.2 °C and 221.1 to 223.4 °C, respectively.
