Evaluation of Crude and Modified Cordia myxa Gum for its Nutraceutical Benefits

Plants are a rich source of safe and valuable bioactive compounds and since ancient times they have been used as medicines. Medicinal herbs are used as traditional means of treating many human diseases in many parts of the world. In current study, the green synthesis pathway was investigated for modification, reducing and crown potential of Cordia myxa gum for the synthesis of silver nanoparticles. The seeding process and the synthesis of silver nanoparticles were tracked by taking ultraviolet/visible absorption spectra during the reaction. Nutritional as well as medicinal potential of raw and modified gums were analyzed. Synthesized spherical nanoparticles were up to 65 nm in size. The ultraviolet/visible spectroscopic results revealed an intense peak at 428 nm together with other small peaks in the region of 390-450 nm due to the presence of nanoparticles of polydispersed silver. The purified gum showed the highest phenolic contents (i.e. 14.71±0.04 mg) and percentage scavenging activity (i.e. 87.92±2.25). The maximum bactericidal activity was showed by nanoformulated gum against Escherichia coli with inhibition zone of 42 mm while minimum was found to be against Staphylococcus aureus with inhibition zone of 14 mm. Nano formulated gum samples also exhibited optimal fungicidal effects against Fusarium solani with inhibition zone of 11.09 mm and Aspergillus niger with inhibition zone of 15.53 mm. The results of current study portrayed that modifications in Cordia myxa gum would be beneficial to food products as an additive.
Phytochemicals, Quality and Glycemic Response Fern Red Herbal (Stenochlaena palustris)

Red fern (Stenochlaena palustris) is an endemic plant that is widely present in open swamps and in tropical rainforests of Borneo. Fern is used as a vegetable by Dayak tribe and has potential for health. Therefore it is necessary to research the utilization of ferns as functional food with the addition of basil leaves as a natural flavor. The research method was performed using Completely Randomized Design (CRD) with a single factor with 6 treats of adding basil leaves of 5 g, 4 g, 3 g, 2 g, 1 g and as a 0 g control. The results of phytochemical analysis on fresh red fern positively contain alkaloids, flavonoids, hydroquinone phenols, steroids, and saponins. The addition of basil leaves has no significant effect on water content, ash content, hedonic and hedonic quality of color, hedonic and hedonic quality of aroma, hedonic and hedonic taste quality, color formation speed without stirring, color forming speed with stirring and color intensity. The best treatment is the addition of basil leaves as much as 5 g with water content of 16.37 ± 4.88%, ash content of 0.95 ± 0.004%, hedonic color like, hedonic quality of brownish red color, aroma rather like, hedonic quality basil-scented aroma, hedonic taste rather like, Hedonic taste very sweet, color formation speed without stirring 7.18 ± 0.75 minutes, color formation speed with stirring 24.85 ± 4.37 seconds, color intensity 0.76 ± 0.05. EC 50 red fern herbal drink is 174,95 ppm. The healthy volunteers who drank a 150 ml red herbal fern drink with the addition of 10 g sugar had a lower glycemic response compared with a control drinking only 150 ml of water with 10 g of sugar added.
Use of KDP crystal as a Kerr nonlinear medium for compressing PW laser pulses down to 10 fs

Abstract The input pulse of the laser PEARL with energy of 18 J and pulse duration of about 60 fs was compressed to 10 fs after passage through a 4-mm-thick KDP crystal and reflection at two chirped mirrors with sum dispersion of −200 fs2. The experiments were performed for the В-integral values from 5 to 19 without visible damage to the optical elements, which indicates that small-scale self-focusing is not a significant issue. It was shown that, by virtue of the low dispersion of the group velocity, the KDP crystal has some advantages over silica: a larger pulse compression coefficient, especially at a small value of the В-integral (B = 5, …, 9), lower absolute values of chirped mirror dispersion, and also a possibility to control the magnitude of nonlinearity and dispersion by changing crystal orientation.
La asociación entre las Actividades de Responsabilidad Social Corporativa y la calidad de los ingresos: Evidencia de la industria extractiva

Building on the ethical theory to solve the research questions, we examine the relationship between Corporate Social Responsibility Disclosure (CSRD) and Earnings Quality (EQ). Using 368 firm-year observations covering the 2010-2017 period. In so doing, we applied content analysis to assess the CSRD dimensions, and we applied discretionary accruals as a proxy of EQ activity. Based on panel data regression, we find a significant and negative relationship between CSRD and EQ in Mozambican extractive industry. Empirical evidence also shows that the influence of positive CSRD indicator (CSRD strengths scores) is much stronger than that negative CSRD indicator (CSRD concerns scores) in reducing earnings quality. These findings are consistent with the idea that the opportunistic managers use CSRD to reach their particular interest, suggesting that the managers are using CSRD as a strategic device to engage in earnings management (poorer earnings quality). The results are robust to alternative proxy measures of CSRD and earnings quality. Con base en la teoría ética para resolver las cuestiones de investigación, examinamos la relación entre Divulgación de Responsabilidad Social Corporativa (CSRD) y la Calidad de los Ingresos (EQ). Usando 368 observaciones de año base cubriendo el período 2010-2017. Al hacer esto, aplicamos el análisis de contenido para evaluar las dimensiones de la CSRD y aplicamos acrecimientos discrecionales como proxy de la actividad de EQ. Con base en la regresión de datos en panel, encontramos una relación significativa y negativa entre el CSRD y el EQ en la industria extractiva de Mozambique. La evidencia empírica también muestra que la influencia del indicador positivo de CSRD (puntuaciones de fuerza CSRD) es mucho más fuerte que el indicador negativo de CSRD (CSRD se refiere a las puntuaciones) en la reducción de la calidad de ingresos. Estas constataciones son consistentes con la idea de que los gerentes oportunistas utilizan la actividad de RSCD para alcanzar su interés particular, sugiriendo que los gerentes están usando el CSRD como un dispositivo estratégico para involucrarse en la gestión de resultados (peor EQ). Los resultados son robustos a medidas alternativas de proxy del CSRD y la EQ. Industria extractiva.
Organizational learning culture in industry 4.0: relationships with work engagement and turnover intention

ABSTRACT The period of digital transformation that we are experiencing, called Industry 4.0, has marked a series of changes in the way we relate as a society, requiring constant adaptation and new knowledge on the part of companies and professionals. This study sought to contribute to the understanding of the relationship between the organizational learning culture in Information Technology companies based in Brazil, the work engagement, and the turnover intention of its employees. Among the results of the correlation and network analyses, it is shown that organizational actions aimed at connecting the organization to its environment dimension have a direct effect on work engagement. The high level of work engagement, on the other hand, has not been shown to reduce the turnover intention. The results of the study allow the identification of cultural aspects related to learning, which dimensions of culture are directly related to work engagement, and what are their impact on the turnover intention. They also evidence elements of the organizational culture to be prioritized in interventions, in addition to offering indications on how to develop professionals within the organizational routine.
The Impact of Civic and Religious Social Capital on the Antisocial Attitudes of the Youth: A Multi-Level Cross-National Study

The main goal of this paper is to investigate whether some dimensions of civic and religious social capital are connected to antisocial attitudes of the youth. Based on the social capital theory and previous research, the author assumed that membership of voluntary associations as a dimension of civic social capital and attendance at religious services as a dimension of religious social capital, will be negatively correlated with antisocial attitudes of the youth. The integrated dataset of the last European Values Study and the World Values Survey waves were used as the sources of the research data. The dataset was comprised of 11,411 respondents who were younger than 25 years old from 79 countries. As hypothesized, at the individual level, attendance at religious services was negatively correlated with antisocial attitudes, whereas membership of voluntary associations was positively correlated with antisocial attitudes. At the country level, none of the hypothesized correlations were confirmed. A cross-level interaction between GDP and associational membership was found. The author explains the findings by evoking the special characteristics of religious social capital and its strength in building moral obligations and by suggesting possible differences in incentives for joining voluntary associations in the countries with different levels of economic wealth.
Trends in the oxidation and relative volatility of chamber-generated secondary organic aerosol

Abstract The relationship between the oxidation state and relative volatility of secondary organic aerosol (SOA) from the oxidation of a wide range of hydrocarbons is investigated using a fast-stepping, scanning thermodenuder interfaced with a high-resolution time-of-flight aerosol mass spectrometer (AMS). SOA oxidation state varied widely across the investigated range of parent hydrocarbons but was relatively stable for replicate experiments using a single hydrocarbon precursor. On average, unit mass resolution indicators of SOA oxidation (e.g., AMS f43 and f44) are consistent with previously reported values. Linear regression of H:C vs. O:C obtained from parameterization of f43 and f44 and elemental analysis of high-resolution spectra in Van Krevelen space both yield a slope of ∼−0.5 across different SOA types. A similar slope was obtained for a distinct subset of toluene/NOx reactions in which the integrated oxidant exposure was varied to alter oxidation. The relative volatility of different SOA types displays similar variability and is strongly correlated with SOA oxidation state (C). On average, relatively low oxidation and volatility were observed for aliphatic alkene (including terpenes) and n-alkane SOA while the opposite is true for mono- and polycyclic aromatic hydrocarbon SOA. Effective enthalpy for total chamber aerosol obtained from volatility differential mobility analysis is also highly correlated with C indicating a primary role for oxidation levels in determining the volatility of chamber SOA. Effective enthalpies for chamber SOA are substantially lower than those of neat organic standards but are on the order of those obtained for partially oligomerized glyoxal and methyl glyoxal. © 2018 American Association for Aerosol Research
1. Introduction

This study highlights the role of economic materialism, i.e., the set of values and personality traits that prioritise the pursuit of material goals, as a cultural phenomenon of significance in relation to economic transformation and development. It presents a model that shows why an endogenous cultural change towards more widespread adherence to materialistic values is both a cause and an effect of productivity growth. This cultural-economic complementarity is a powerful mechanism of endogenous productivity growth; it also determines the prevalence of different cultural values vis-à-vis the prominence of material objectives. The model’s calibration reveals that its outcomes offer a reasonably good fit for the differences in the evolution of income per capita in England and France between 1500 and 1880.
Jahn–Teller distortion in 2-pyridyl-(1,2,3)-triazole-containing copper(II) compounds

The syntheses, characterization and experimental solid state X-ray structures of five low-spin paramagnetic 2-pyridyl-(1,2,3)-triazole-copper compounds, [Cu(Ln)2Cl2], are presented in this study, for the following five Ln ligands: L1 = 2-(1-(p-tolyl)-1H-(1,2,3-triazol-4-yl)pyridine), L2 = 2-(1-(4-chlorophenyl)-1H-(1,2,3-triazol-4-yl)pyridine), L3 = 4-(4-(pyridin-2-yl)-1H-(1,2,3-triazol-4-yl)benzonitril), L4 = 2-(1-phenyl-1H-(1,2,3-triazol-4-yl)pyridine) and L5 = 2-(1-(4-(trifluoromethyl)phenyl)-1H-(1,2,3-triazol-4-yl)pyridine). These five [Cu(Ln)2Cl2] complexes each contain two bidentate 2-pyridyl-(1,2,3)-triazole (Ln) and two chloride ions as ligands, with the Cu–N(pyridine) bonds, Cu–N(triazole) and Cu–Cl bonds trans to each other. All five [Cu(Ln)2Cl2] compounds display elongation Jahn–Teller distortion, either along opposite Cu–N(triazole) bonds, or along opposite Cu–Cl bonds, as indicated by their obtained solid state crystal structures. Quantum chemistry calculations, using density functional theory, indicated however that elongation Jahn–Teller distortion is in fact possible along any two opposite bonds in these octahedral compounds with the elongation distortion along the opposite Cu–N(triazole) bonds being the most stable structure.
Frequency filter for elastic bending waves: Poincaré map method and experiment

In this work, the Poincaré map numerical method was successfully developed to solve the fourth-order differential equation that describes the flexural vibrations of a beam, within the Timoshenko beam theory. The Euler-Bernoulli continuity conditions were considered, which are valid for frequencies smaller than the critical frequency. As an example, this method was used to design a complex elastic structure, characterized by a flexural frequency spectrum with a broad band gap. Such structure consists of two coupled phononic crystals, which were designed with filling factor values in such a way that in their bending frequency spectra, an allowed band of the first part, overlaps with a band gap of the second one and vice versa. The resulting composed system has a much wider effective gap than its original components, between 4 and 10.5 kHz. This system works as an elastic bending wave filter. Finally, these three structured elastic systems were constructed, and characterized by the acoustic resonance spectroscopy technique. The natural flexural frequencies as well as the corresponding wave amplitudes of each structured beam were measured. The experimental measurements show excellent agreement with the numerical simulation.
Bridging international political economy and public policy and administration research on central banking

ABSTRACT Central banking as an avenue of research has been of interest to scholars from International Political Economy (IPE) and Public Policy and Administration (PPA) disciplines. Nevertheless, there is very little dialogue between these two perspectives to bridge macro, meso, micro-level analyses and examine the reciprocal relationship between the global and domestic political economy context and monetary policy conduct. This article investigates the Turkish experience to bridge IPE and PPA scholarship on central banking in emerging economies. In doing so, we adopt an analytic eclectic approach combining multiple structural, institutional, and agential causal explanations with particular reference to the Structure, Institution, and Agency (SIA) theoretical framework. This is because analytic eclecticism complements, speaks to, and selectively incorporates theoretical approaches such as the New Independence Approach (NIA) of IPE and institutional and ideational PPA approaches. Drawing on the empirical context of the historical evolution of the Turkish political economy, we explore domestic and international interactions among micro, meso, and macro levels that shape central banking behavior. Our analysis also reveals how global dynamics are translated into domestic policy choices and how particular ideas influence the policymaking process. The analysis underscores the constraining and enabling influence of international dynamics, politics of ideas on emerging economy central banking, and the essential role individual and organizational agency play in the policymaking process.
Trends in Antarctic ozone hole metrics 2001–17

Linear trends over the years 2001–17 are reported of a number of standard metrics used to describe the severity of the Antarctic ozone hole, both with and without a simple adjustment to account for meteorological variability. The trends were compared to those from the years 1979–2001. All metrics considered showed a trend towards reduced ozone depletion since 2001, at significance levels ranging from 2.4 to 3.9 standard errors of the trend after the adjustment was performed. The adjustment for meteorological variability had little effect on the values of the trends but did substantially reduce the scatter and, therefore, uncertainty of the trends.
Quality Evaluation and Acceptability of Cookies Produced From Rice (Oryza glaberrima) and Soybeans (Glycine max) Flour Blends

ABSTRACT This study was carried to evaluate the quality attributes and acceptability of cookies produced from rice (Oryza glaberrima) and soybeans (Glycine max) flour blends, a gluten-free product. Simplex lattice design was used for product formulation that provided five experimental runs of rice flour and soy beans flour composites. Five composite flour samples were mixed in the following ratios 100:0, 95:5, 90:10, 85:15 and 80:20. Cookie samples produced from the combinations were evaluated for proximate, anti-nutrients, amino acids and vitamins profile analyses and sensory evaluation. Results showed (P ≤ 0.05) that the protein contents in % ranged from 8.94 ± 0.01 to 17.51 ± 0.03% while tannin, phytates, trypsin inhibitors and protease inhibitors in mg/100g ranged from 34.63 ± 0.06 to 70.82 ± 0.06, 69.82 ± 0.08 to 98.83 ± 0.09, 30.62 ± 0.02 to 69.61 ± 0.08 and 28.27 ± 0.02 to 64.79 ± 0.08, respectively. The thiamine, niacin and riboflavin contents in mg/100g for the cookies produced from rice and soybean flour blends with 0%, 5%, 10%, 15%, and 20% soy beans flour substitution were 0.41 ± 0.01, 0.53 ± 0.01, 0.59 ± 0.01, 0.68 ± 0.01 and 0.77 ± 0.01 for thiamine, 3.22 ± 0.02, 3.31 ± 0.02, 3.63 ± 0.02, 3.74 ± 0.02 and 3.89 ± 0.02 for niacin, 0.18 ± 0.00, 0.30 ± 0.00, 0.46 ± 0.01, 0.58 ± 0.01 and 0.70 ± 0.01 for riboflavin, respectively. The results of sensory evaluation also showed that increase in the level of soy beans flour in the composite rice flour improved overall acceptability of the cookies. Furthermore, cookies with 85% rice flour and 15% soybean flour had the highest overall acceptability value of 7.6. Cookies with 85% rice flour and 15% soybean flour also had the highest ratings in terms of crispiness, texture, flavour, taste and colour.
Body difficulties in junior rhythmic gymnastics according to the fig code of points

This study aimed at analysing the 2018 European Championships from the perspective of rhythmic gymnastics routines at junior level, based on the criterion of difficulty elements and execution times, taking into consideration the current FIG Code of Points. Secondly, we aimed at comparing the finalists’ routines with those of the Romanian gymnasts according to the same criterion. Data were collected using the video analysis of 39 routines performed during the qualifications and finals for four apparatus: hoop, ball, clubs and ribbon. The investigated gymnasts were aged between 13 and 15 years. Descriptive statistics were used for the following cues: number of difficulty elements divided by body and apparatus difficulties and their contribution to the maximal number allowed, along with the scores and execution times for all difficulty elements performed in the routines. Data reveal several interesting aspects related to: the ratio between the number and value of the difficulty elements determined by the gymnasts’ capabilities and their prevalence in the four apparatus events; the implications of the Code of Points difficulty provisions on the variety of compositions; the relevance of the execution times for the possibility of adding more difficulty elements; the differential notes of the Romanian gymnasts’ compositions and their weight in the final score. The Code of Points puts an emphasis on the apparatus handling variety, with implications on the uniqueness and spectacular effects on the judges and public.
Analysis of Online Learning Readiness in College Students and Its Implications for Higher Education

Readiness to learn online is a determining factor for student success in learning, especially in the digital era. This study aims to analyze online learning readiness among students at a state university in Jakarta, Indonesia. This study involved 245 college students who were randomly selected. Measurement of online learning readiness data uses the Student Online Learning Readiness or SOLR (Yu & Richardson, 2015). SOLR instruments consist of four dimensions: technical competence, social competence with the instructor, social competence with classmates, and communication competence. This instrument consists of 20 statement items. The data that has been collected is processed and analyzed using descriptive statistics. The results showed that students' online learning readiness was quite a good category. The implications of this study will be discussed.
Smart Fertilization Based on Sulfur–Phosphate Composites: Synergy among Materials in a Structure with Multiple Fertilization Roles

Sulfur is currently a bottleneck for agronomic productivity. Many products are based on the application of elemental sulfur (S°), but the ability of the soil to oxidize them is variable and dependent on the presence of oxidizing microorganisms. In this work, a composite was designed based on a matrix of S° prepared by low-temperature extrusion, reinforced by rock phosphate particles acting as P fertilizer, and with encapsulation of Aspergillus niger as an oxidizing microorganism. This structure was shown to be effective in significantly increasing S° oxidation while providing P by rock phosphate dissolution in an acid environment. X-ray absorption near-edge structure (XANES) spectra provided information about P fixation in the soil after dissolution, showing that the composite structure with A. niger modified the nutrient dynamics in the soil. This fully integrated material (a smart fertilizer) is an innovative strategy for eco-friendly agronomic practices, providing high nutrient delivery with minimal so.
Students’ and teachers’ perceptions of self-assessment and teacher feedback in foreign language teaching in general upper secondary education – A case study in Finland

Abstract This qualitative case study examined how foreign language teachers in Finnish general upper secondary schools enhance self-regulated learning (SRL) with self-assessment and teacher feedback. Nine students and ten teachers from six schools were interviewed, and the data were analyzed using content analysis. The results revealed that self-assessment is used in courses but not extensively, and most teachers do not teach their students to self-assess their learning. Most students consider teacher feedback to be useful, but they reported a lack of oral feedback. The participants expressed contradictory perceptions regarding their motivation, as students do not find teacher feedback to be motivating, while teachers believe their feedback is motivating. To a certain extent, teachers enhance SRL with self-assessment and feedback, but their practices could be improved.
