Progress toward new Reference Correlations for the Transport Properties of Carbon Dioxide | NIST

While the thermodynamic properties of CO2 are available with excellent accuracy from the referencequality equation of state of Span and Wagner, the current reference correlations for transport properties (thermal conductivity and viscosity) are relatively old and have significant room for improvement. We describe current work at NIST to improve the data situation for both transport properties. For the viscosity, new theoretical results for the dilute vapor and a semitheoretical scaling approach for the liquid allow us to produce an improved correlation. In the case of the thermal conductivity, we measured new data with a transient hot-wire instrument. These measurements cover temperatures from 219 K to 751 K at pressures up to 69 MPa, with uncertainties near 0.5 % for the liquid and compressed gas, increasing to 3 % for low-pressure gases and conditions very near the critical point. This improves the uncertainty at most conditions by more than a factor of two compared to previous measurements. These new data, in combination with literature data and theoretical results for the dilute gas, are being employed to produce a new standard correlation for the thermal conductivity as a function of temperature and density. The new correlation will employ state-of-the-art theory to incorporate the near-critical enhancement of the thermal conductivity that is significant in a sizable region around the critical point.
Discovering what makes a SME website good for international trade

The effectiveness of websites has an impact on the representation of a SME and can have an effect on foreign trade. Thus, developing a reliable and robust model to assess the effectiveness of SME websites is important for researchers and practitioners. The aim of the study is to propose a SME website efficiency evaluation methodology from an international trade perspective. Determining the effectiveness of websites is a multi-dimensional decision-making problem which encompasses the assessment of information quality, system quality, and service quality. The criteria and sub-criteria affecting website effectiveness were determined through literature research and expert panel assistance. AHP method was utilized to determine the relative weights of the evaluation criteria in the study. Then, fuzzy linguistic variables were adopted to rank the websites of SMEs engaged in foreign trade. The proposed evaluation model identifies key factors regarding the criteria and sub-criteria of a website effectiveness. The model can provide a helpful reference in designing useful websites which are an important task for SMEs involved in international trade.
Seismology of curved coronal loops with vertically polarised transverse oscillations

Aims. Using a model of vertically polarised fast magnetoacoustic waves in curved coronal loops, the method of coronal seismology is applied to observations of transverse loop oscillations. Methods. A coronal loop is modeled as a curved magnetic slab in the zero plasma-β limit. For an arbitrary piece-wise continuous power law equilibrium density profile, the dispersion relation governing linear vertically polarised fast magnetoacoustic kink waves is derived. The ways in which this model can be used for coronal seismology are explored and applied to two observational examples. Results. The Alfven speed and equilibrium density profile are determined from observations. It is shown that the mechanism of lateral leakage of fast magnetoacoustic kink oscillations described in this model is efficient. In fact, the damping is so efficient that in order to match predicted values with observational ones, either the loop needs to be highly contrasted or the transverse Alfven speed profile needs to be close to linear. Possible improvements to make the modeling of lateral wave leakage in loops more realistic, allowing a lower damping efficiency, are discussed.
Change‐Point Detection in the Conditional Correlation Structure of Multivariate Volatility Models

ABSTRACT We propose semiparametric CUSUM tests to detect a change-point in the correlation structures of nonlinear multivariate models with dynamically evolving volatilities. The asymptotic distributions of the proposed statistics are derived under mild conditions. We discuss the applicability of our method to the most often used models, including constant conditional correlation (CCC), dynamic conditional correlation (DCC), BEKK, corrected DCC, and factor models. Our simulations show that, our tests have good size and power properties. Also, even though the near-unit root property distorts the size and power of tests, de-volatizing the data by means of appropriate multivariate volatility models can correct such distortions. We apply the semiparametric CUSUM tests in the attempt to date the occurrence of financial contagion from the US to emerging markets worldwide during the great recession.

Elementary School Entry: Stress, Competence and Adjustment in First Grade Students

This study aimed to compare children from the 1st year of Elementary Education (EE) with or without stress symptoms regarding indicators of adjustment and competence related to academic, social, and behavioral domains, separately for boys and girls. The participants were 85 boys and 72 girls. Twentyfi ve teachers participated as informants. The children answered the Childhood Stress Scale, the School Hassles Inventory and the academic test Provinha Brasil. The teachers evaluated the social skills and externalizing, and internalizing behavior problems of the children using the Social Skills Rating System. There was no gender difference in self-reported stress symptoms. Girls outperformed boys in the academic achievement test. The teachers rated the girls as more socially skilled and the boys with more externalizing behavior problems. In the comparison of the children with or without stress symptoms, boys with stress were disadvantaged in all variables. Among girls, a similar pattern was found for six out of the 10 variables studied. The results suggest that children that are more competent deal more easily with the transitional requirements of the fi rst year in EE. These children fi nd the adaptive tasks less stressful, which appears to make them less susceptible to the adverse effects of stress.
body image in adolescence than in emerging adulthood : A gender comparison in a follow-up study

background Body image dissatisfaction has been linked with a range of adverse psychosocial outcomes in both genders and has become an important public health issue. Across all ages, women have reported being more dissatisfied with their bodies than men. The aim of the current study was to examine if fitness and physical activity associate with body image satisfaction differently across gender and age, measured in the same participants.
Changes in the timing and duration of the near-surface soil freeze/thaw status from 1956 to 2006 across China

Abstract. The near-surface soil freeze/thaw status is an important indicator of climate change. Using data from 636 meteorological stations across China, we investigated the changes in the first date, the last date, the duration, and the number of days of the near-surface soil freeze over the period 1956–2006. The results reveal that the first date of the near-surface soil freeze was delayed by about 5 days, or at a rate of 0.10 ± 0.03 day yr−1, and the last date was advanced by about 7 days, or at a rate of 0.15 ± 0.02 day yr−1. The duration of the near-surface soil freeze decreased by about 12 days or at a rate of 0.25 ± 0.04 day yr−1, while the actual number of the near-surface soil freeze days decreased by about 10 days or at a rate of 0.20 ± 0.03 day yr−1. The rates of changes in the near-surface soil freeze/thaw status increased dramatically from the early 1990s through the end of the study period. Regionally, the changes in western China were greater than those in eastern China. Changes in the near-surface soil freeze/thaw status were primarily controlled by changes in air temperature, but urbanization may also play an important role.
Mathematik in den Naturwissenschaften Leipzig A constitutive model for granular materials with grain crushing by

A constitutive model for granular materials is developed within the framework of strain–hardening elastoplasticity, aiming at describing some of the macroscopic effects of the degradation processes associated with grain crushing. The central assumption of the paper is that, upon loading, the frictional properties of the material are modified as a consequence of the changes in grain size distribution. The effects of these irreversible microscopic processes are described macroscopically as accumulated plastic strain. Plastic strain drives the evolution of internal variables which model phenomenologically the changes of mechanical properties induced by grain crushing by controlling the geometry of the yield locus and the direction of plastic flow, An application of the model to Pozzolana Nera is presented. The stress–dilatancy relationship observed for this material is used as a guidance for the formulation of hardening laws. One of the salient features of the proposed model is its capability of reproducing the stress–dilatancy behaviour observed in Pozzolana Nera, for which the minimum value of dilatancy always follows the maximum stress ratio experienced by the material. ∗Università degli Studi di Perugia, via G.

Chinese Validation of the Team Climate Inventory: A Measure of Team Climate for Innovation in R&D Teams

The team climate inventory (TCI) is a facet-specific measure of team climate for innovation. The present study assessed the psychometric properties and the validity of the Chinese translation of TCI in 208 group members from 31 teams employed in RD context. The data were evaluated by means of rwg(j) values, Cronbach's alpha coefficient, confirmatory factor analysis, and Pearson's product moment correlations. The acceptable rwg (j) values showed appropriate internal consistency of the scales, Cronbach's alpha revealed satisfactory reliabilities and exploratory factor analysis successfully extracted a five -factor structure of the inventory, and Pearson's product moment correlation matrix indicated adequate levels of intra -scale correlation. Criterion validity was explored by correlating TCI scores with self-reported innovativeness scores. Significant positive relationships were found between five TCI scales and perceived innovativeness. Compared to the original TCI, Chinese version of the TCI is a reliable and valid instrument for measuring team climate for innovation also in RD context.

Bipolar disorder is also known as manic depression because a person’s mood can alternate between manic state and depressive state. This study presents a case of MR. X of 57 years of age. He was brought Fouji Foundation hospital with the symptoms insomnia, distractibility, racing thoughts and poor judgement and rapid ups and down in mood. Diagnosed was made according to DSM-5. Through detail examination it was concluded that his sign and symptoms are due to his circumstances not due to any biological or neurological deficits. Client was successfully treated cognitive and behavioural therapies. The client showed significant improvement in his condition.
The enigma of the 10-year wildlife population cycle solved? Evidence that the periodicity and regularity of the cycle are driven by a lunar zeitgeber

Despite nearly 100 years of research, the periodicity and regularity of the 10-year wildlife population cycle remain an enigma. This paper presents the hypothesis that the 9.3-year nodal half-cycle of the moon is the zeitgeber (“time-giver”) of the 10-year wildlife population cycle. The period of the population cycles of the Snowshoe Hare ( Lepus americanus ) and Ruffed Grouse ( Bonasa umbellus ) is close to 9.3 years. These wildlife cycles have stayed closely in phase with the 9.3-year nodal half-cycle for 150 years. Population density of the Snowshoe Hare and Ruffed Grouse is inversely related to a 9.3-year cycle of the moon's tidal force. There is also a 9.3-year cycle of “nights without darkness” at the equinoxes, in which the full moon rises before sunset and sets after sunrise the following morning in certain years. Snowshoe Hare and Ruffed Grouse cycles are positively correlated with this phenomenon. The nodal cycle provides explanations for the key features of the 10-year wildlife cycle: regularity, periodicity, amplitude, distribution, and synchrony. Population models based solely on the nodal cycle account for 62% of the variation in the Canada Lynx ( Lynx canadensis ) cycle and 37% in the Ruffed Grouse cycle. The mechanism(s) by which herbivore cycles might be entrained by the lunar nodal cycle could involve a cyclic effect on factors including predation, stress, photoperiod, phenology, temperature, cloudiness, ultraviolet B radiation, cosmic rays, and food plant quality.
Quantitative suspension tests for the evaluation of bactericidal, fungicidal and sporicidal effects of biocides used in vaccine production facility

The appropriate use of biocides is essential in any vaccine production facility and their proper evaluation using standardized tests marks the first step to ensure their proper use. Quantitative suspension tests against reference and environmental isolates were carried out to evaluate the efficacy of various biocides used in the main vaccine production facility in Egypt. Several use-dilutions of the biocides were evaluated at contact times of up to 5 min in case of antiseptics and 30 min in case of disinfectants to measure the biocide activity against bacteria, fungi and spores. Standard strains were used in addition to the main bacterial isolates identified in an environmental monitoring program carried out in the same facility. Alcohol based biocides showed bactericidal and fungicidal activity but no sporicidal activity. Chlorine based compounds and glutaraldehyde showed bactericidal and fungicidal effect while, the sporicidal effects depended on the used dilution and the contact time. Hydrogen peroxide showed bactericidal, fungicidal and sporicidal activity. Quaternary ammonium compounds tested showed very weak activity in all tests. Evaluation of the biocide is an essential step to guarantee the use of the most appropriate agent in any location. Key words: Biocides, antiseptics, disinfectants, vaccines, Egypt.
Comparison of fibroblast and osteoblast response to cultivation on titanium implants with different grain sizes

The in vitro response of human fibroblast cell line HFL1 and human osteoblast cell line hFOB 1.19 on nanostructured titanium with different grain sizes has been compared in the present study. Used samples of titanium produced by equal channel angular (ECA) pressing have grain sizes of 160 nm, 280 nm, and 2400 nm with cross- and longitudinal sections. Similar cellular behaviour was observed on all studied biomaterials. There were significant differences related to the initial phase of attachment, but not in proliferation. Furthermore, the results indicate that osteoblasts grow best on material with grain size of 160nm with a longitudinal section in comparison with other examined materials. Therefore, this material could be recommended for further evaluation with respect to osseointegration in vivo.
BUILDING ECOLOGICAL INTELLIGENCE THROUGH INDONESIAN LANGUAGE LEARNING BASED ON KETHEK OGLENG DANCE

Kethek Ogleng is a unique factor that shapes the aesthetics of language learning. Unfortunately, the relation between Kethek Ogleng and language learning draws only a little attention. To reveal the phenomenon, the present qualitative descriptive study was performed by investigating Indonesian language learning based on Kethek Ogleng dance. The study was conducted in SMPN (State Junior High School) 3 Nawangan, to the second semester ninth grade students of the 2017/2018 academic year. The research findings reveal that the approach can build the level of ecological intelligence of the students. Based on the responses to the questionnaire distributed, the average level of ecological intelligence and environmental skills of the students shows signs of progress. The data indicate that the mean score was 3.2 and the percentage of ecological intelligence was 65%, indicating the attainment of knowledge and skills of school and home environment preservation. The indicators of the success of this approach can be seen in the changes of attitude and behavior of students in environmental management, covering clean and healthy classrooms and toilets, the use of recyclable materials, water and electricity conservation in the classroom, protection of trees and plants around the classrooms, proper treatment of trash, and organic and inorganic waste utilization.
Subliminal In uence on Generosity*

We experimentally subliminally prime subjects prior to charity donation decisions by showing words that have connotations of pro-social values for a very brief time (17ms). Our main nding is that, compared to a baseline condition, the pro-social prime increases donations by approximately 10-17 percent among subjects with strong pro-social preferences (universalism values). We nd a similar e ect when interacting the prime with the Big 5 personality characteristic of agreeableness. We furthermore introduce a novel method for testing for priming, "subliminity". This method reveals that some subjects are capable of recognizing prime words, and the overall results are weaker when we control for this capacity.
Learning With Technology: The Impact of Laptop Use on Student Achievement

Rapid technological advances in the last decade have sparked educational practitioners’ interest in utilizing laptops as an instructional tool to improve student learning. There is substantial evidence that using technology as an instructional tool enhances student learning and educational outcomes. Past research suggests that compared to their non-laptop counterparts, students in classrooms that provide all students with their own laptops spend more time involved in collaborative work, participate in more project-based instruction, produce writing of higher quality and greater length, gain increased access to information, improve research analysis skills, and spend more time doing homework on computers. Research has also shown that these students direct their own learning, report a greater reliance on active learning strategies, readily engage in problem solving and critical thinking, and consistently show deeper and more flexible uses of technology than students without individual laptops. The study presented here examined the impact of participation in a laptop program on student achievement. A total of 259 middle school students were followed via cohorts. The data collection measures included students’ overall cumulative grade point averages (GPAs), end-of-course grades, writing test scores, and state-mandated norm- and criterion-referenced standardized test scores. The baseline data for all measures showed that there was no statistically significant difference in English language arts, mathematics, writing, and overall grade point average achievement between laptop and non-laptop students prior to enrollment in the program. However, laptop students showed significantly higher achievement in nearly all measures after one year in the program. Cross-sectional analyses in Year 2 and Year 3 concurred with the results from the Year 1. Longitudinal analysis also proved to be an independent verification of the substantial impact of laptop use on student learning outcomes.
The impact of pension reforms and demography on stock markets

Population aging is just beginning to hit the industrialized countries in full force, and it will have a tremendous impact on capital markets. Capital market effects of population aging are particularly strong in continental European economies such as Germany, with their large pay-as-you- go public pension systems. The younger generations in these countries are becoming aware of the need to provide for more retirement income through own private saving, and these effects will be accentuated by fundamental pension reforms that aim at more pre-funding. Population aging therefore changes householdsâ€™ savings behavior and portfolio composition, and much more assets will be invested in the stock market. Capital markets will grow in size, and active institutional investors such as pension funds are likely to become more important in continental European countries.
Recovering the Rotational Light Curve of Phoebe

We present rotational light-curve data for Saturn's satellite Phoebe taken over the observing period prior to the Cassini mission's encounter with that moon. We find a rotation period of 9.2735 ± 0.0006 hr, a factor of 25 improvement in the rotation period's uncertainty over previously published data. This improved rotation period measurement allow s us to correlate previously observed spectral features and colors with albedo features observed by Voyager and to predict which side of Phoebe will be observed by Cassini during its 2004 June 11 encounter. The light curve, sampled at subobserver latitudes farther south than achieved by Voyager, shows evidence of surface features that cannot be explained by previously published shape models or albedo maps and that may be located in the regions in Phoebe's southern hemisphere that were unobserved by Voyager.
