Single crystal elasticity of lawsonite

Abstract The single-crystal elastic moduli of lawsonite [CaAl2(Si2O7)(OH)2·H2O] were measured by Brillouin spectroscopy at ambient conditions. The Voigt-Reuss-Hill averaged aggregate elastic moduli are KS = 125(2) GPa and μ = 52(2) GPa, for the adiabatic bulk modulus and shear modulus, respectively. Our acoustic results resolve discrepancies between the bulk moduli obtained in earlier compression studies. Lawsonite has distinctive acoustic properties, being characterized by extremely high shear elastic anisotropy (74%), a high VP to VS ratio (VP/VS = 1.94), and a large Poisson’s ratio (σ = 0.318)
Smart Automated Language Teaching Through the Smart Sender Platform

The purpose of the research was to identify whether the English language e-classes that are automated and delivered through the Smart Sender platform influence the students’ attendance and procrastination rates, their motivation, time management skills, cognitive processing speed, and satisfaction. The study used qualitative and quantitative methods to monitor students’ attendance and procrastination rates, motivation and engagement, time management skills, thinking speed, and satisfaction. The questionnaire on learning motivation, engagement, and competence, the time management skills test, the mental speed test, and the course satisfaction questionnaire were used to collect data. The focus group discussion questionnaire was used to obtain verbal feedback for the participants. The Smart Sender platform proved effective as an instructional tool for teaching the English Language to students majoring in Philology, International Business, and Law. The automated delivery of the English language e-classes was effective in addressing the issues of dropouts and procrastination in distance learning through automation of the lesson delivery based on the ‘push’ factor. It increased students’ motivation, improves time management skills, and satisfaction. The quantitative findings showed that the students experienced a positive change in attendance, motivation and learning engagement, time management skills, and thinking speed due to the intervention. The students perceived the automated delivery-based approach to language teaching positively. They reported that the delivery approach content met the participants’ expectations and needs. Focus group discussion revealed that the intervention changed their learning behaviour and strategies which were considered the improvements of the quality learning outcomes.
Integrated Equine-Assisted Short Term Psychodynamic Psychotherapy (EASTPP) equals regular STPP and outperforms in overcoming core problems of patients with personality problems: interpersonal sensitivity and self esteem

Introduction: Patients with personality pathology need interventions which include opportunities for intersubjective relations to emerge on both verbal and nonverbal levels. The aim of this study is to investigate if equine-assisted psychotherapy integrated in Short Term Psychodynamic Psychotherapy facilitates these nonverbal components and intersubjective relations compared to regular Short Term Psychodynamic Psychotherapy (STPP)
Serum levels of Vitamin D3, Zinc, and Parathyroid Hormone in HCV-induced Hepatocellular Carcinoma.

Background and AimThe role of the metabolic syndrome in hepatocellular carcinoma (HCC) has been previously reported. This study aims to investigate the possible role of vitamin D3, Zinc, Parathyroid hormone (PTH), calcium and phosphorus serum levels as non-traditional metabolic risk factors in HCV-related HCC.MethodThis cross-sectional observational study recruited HCV infected patients with and without HCC. All patients were subjected to demographic, biochemical, and hematological assessment. Serum levels of vitamin D3, Zinc, PTH, calcium, and phosphorus were determined in all the study participants.ResultsThis study includes 50 patients with HCV-related HCC compared to 40 patients with HCV-related liver cirrhosis and 30 patients with HCV chronic hepatitis C (CHC) without HCC. Our results show significantly higher age, male sex, aspartate transaminase (AST), PTH and corrected serum calcium levels in the HCC patients compared to values in the other two groups, (p < 0.001); while significant lower vitamin D3 and zinc levels were detected among the HCC patients compared to patients with non-HCC liver cirrhosis and CHC, (p < 0.001). Vitamin D3 deficiency was detected in 96% of the HCC patients, while it was detected in only 22.5% of the cirrhotic patients and in none of the CHC patients, (p < 0.001). However, on multiple stepwise regression analysis, only the age, AST, PTH, and corrected calcium levels were the independent predictors for HCC when studied in relation to chronic liver disease.ConclusionThis study indicates the prevalent deficient levels of vitamin D3 and zinc in HCC patients; however, a causal relationship is not established in this study.
Projection Bias and Youth’s and Parents’ Perceptions of Their Joint Political Discussions

ABSTRACT This study investigated the idea that youth’s perceptions of the frequency of family political discussions and of parental political support mostly derive from their own political interest, a form of projection bias. Tests were performed of whether the same bias applies to parents, and whether youth’s and parents’ perceptions of political discussions and political support overlap to only a limited extent. Multivariate multiple regression analyses, combining two age cohorts of adolescent-parent pairs (509 13-year-olds and 541 16-year-olds), supported these expectations, indicating that parents and youth live, at least in part, in different perceptual worlds. These findings explain differences in youth’s and parents’ reports of political interactions, illuminate the theoretical models indicating that family discussions determine whether or not a child is interested in politics, and show the limitations of relying solely on reports of either youth or parents when studying the influence of family political discussions on youth’s political development.
Image translation between high-resolution optical and synthetic aperture radar (SAR) data

ABSTRACT This paper presents a novel study: remote-sensing image translation between high-resolution optical and Synthetic Aperture Radar (SAR) data through machine learning approaches. To this end, conditional Generative Adversarial Networks (cGANs) have been proposed with the guide of high-level image features. Efficiency of the proposed methods have been verified with different SAR parameters on three regions from the world: Toronto, Vancouver in Canada and Shanghai in China. The generated SAR and optical images have been evaluated by pixel-based image classification with detailed land cover types including: low and high-density residential area, industry area, construction site, golf course, water, forest, pasture and crops. Results showed that the translated image could effectively keep many land cover types with compatible classification accuracy to the ground truth data. In comparison with state-of-the-art image translation approaches, the proposed methods could improve the translation results under the criteria of common similarity indicators. This is one of first study on multi-source remote-sensing data translation by machine learning.
Viromics of extant insect orders unveil the evolution of the flavi-like superfamily

Abstract Insects are the most diversified and species-rich group of animals and harbor an immense diversity of viruses. Several taxa in the flavi-like superfamily, such as the genus Flavivirus, are associated with insects; however, systematic studies on insect virus genetic diversity are lacking, limiting our understanding of the evolution of the flavi-like superfamily. Here, we examined the diversity of flavi-like viruses within the most complete and up-to-date insect transcriptome collection comprising 1,243 insect species by employing a Flaviviridae RdRp profile hidden Markov model search. We identified seventy-six viral sequences in sixty-one species belonging to seventeen insect, one entognathan, and one arachnidan orders. Phylogenetic analyses revealed that twenty-seven sequences fell within the Flaviviridae phylogeny but did not group with established genera. Despite the large diversity of insect hosts studied, we only detected one virus in a blood-feeding insect, which branched within the genus Flavivirus, indicating that this genus likely diversified only in hematophagous arthropods. Nine new jingmenviruses with novel host associations were identified. One of the jingmenviruses established a deep rooting lineage additional to the insect- and tick-associated clades. Segment co-segregation phylogenies support the separation of tick- and insect-associated groups within jingmenviruses, with evidence for segment reassortment. In addition, fourteen viruses grouped with unclassified flaviviruses encompassing genome length of up to 20 kb. Species-specific clades for Hymenopteran- and Orthopteran-associated viruses were identified. Forty-nine viruses populated three highly diversified clades in distant relationship to Tombusviridae, a plant-infecting virus family, suggesting the detection of three previously unknown insect-associated families that contributed to tombusvirus evolution.
A novel carrier element‐free co‐precipitation method for separation/preconcentration of lead and cadmium ions from environmental matrices

A new separation and pre‐concentration method was presented in this study for two trace heavy metal ions, lead (Pb2+) and cadmium (Cd2+) from aqueous solutions, based on a carrier element free co‐precipitation (CEFC) method using a triazole derivate, 3‐(4‐tert‐butylphenyl)−5‐phenyl‐4‐(2‐hydroxy‐5‐methoxybenzylamino)−4H‐1,2,4‐triazole as an organic co‐precipitating agent. The method was optimized with some analytical parameters which affect the quantitative recoveries of study metals. According to the results, optimum pH of solution, quantity of co‐precipitating agent, centrifugation and incubation time, and sample volume were determined as 6.0, 1.5 mg, 10 min, and 10 min, and 100 mL, respectively. In addition, no significant matrix interferences were observed over the recovery of the metal ions. For analytical figure of merit, RSD values of the method were found as 5.7 and 4.8 for Pb2+ and Cd2+, respectively. LOD values were also calculated as 2.0 µg L−1 for Pb2+ and 0.2 µg L−1 for Cd2+. The accuracy of method was checked with spiked/recovery tests and analysis of a standard reference material. The developed method was finally applied to the real liquid/solid samples under the optimum conditions. © 2016 American Institute of Chemical Engineers Environ Prog, 35: 1709–1715, 2016
Preparation and Characterization of Polyamidoamine G2.0-Hematin as a Biocatalyst for Fabricating Catecholic Gelatin Hydrogel

In this study, we report that an enzyme-mimicking biocatalyst polyamidoamine (PAMAM) dendrimer G2.0-hematin (G2.0-He) was fabricated successfully. The chemical structure of G2.0-He was verified by 1H NMR and FT-IR spectroscopy. G2.0-He exhibited a size distribution from 11.6 ± 1.7 nm to 12.5 ± 2.9 nm and a zeta potential from 32.5 mV to 25.6 mV along with the enhancement of the hematin conjugation degree. The relative activity of G2.0-He was evaluated based on pyrogallol oxidation reactions at pH = 7 . The results showed that G2.0-He was more stable than horseradish peroxidase (HRP) enzyme in high H2O2 concentrations. The HRP-mimic ability of G2.0-He was also confirmed by the catalyzation when preparing catecholic gelatin hydrogels under mild conditions. Moreover, our results also revealed that these hydrogels performed with excellent cytocompatibility in an in vitro study and could be used as a potential scaffold for adhesion and proliferation of fibroblast cells. The obtained results indicated that G2.0-He is a suitable platform for altering the HRP enzyme in several biomedical applications.
On the Indian Tradition of Mathematical Names: A Scientific Analysis

The current paper explores the potential interlink between names of individuals in a society and its collective social consciousness, particularly with reference to the pervasive occurrence of the ‘mathematical names’ in the current Hindu society in the Indian subcontinent and beyond. Initially, an attempt is made to put things into mathematical perspective by drawing a quick sketch of some of the stellar achievements of the Indian mathematicians. Under the six broad categories of geometry, trigonometry, numeration, arithmetic, algebra, and mathematics in the Vedic tradition, a concise simple description of these subdivisions is presented, underlining the names of the concepts and terms, sometimes by producing the textual references. Then, upon identification of such mathematical terms, an attempt is made to juxtapose these with the names current in the Indian Hindu society. By employing an extensive dataset of university student names in India and the directories of Facebook and LinkedIn, we produce both qualitative and quantitative evidence of the presence of such names in the Indian subcontinent. Evidently, these names reflect the impressions of the tremendously rich mathematical heritage left by the Hindu stalwart mathematicians. This hypothesis has also been examined by taking surveys of people bearing these mathematical names, as well as by documenting the ‘conscious procedures’ that go behind the naming of a Hindu Indian child. In trying to investigate if such a phenomenon is unique to the Indian tradition, a stark contrast with the ‘names in mathematics’ as prevalent in the European mathematical traditions is presented, as cultural roots of mathematics are explored. Further, we ascribe the presence of these names as the extant remains of the colossal impact of multifarious mathematical traditions existing in India. Interestingly, the present research also brings to the fore, certain unseen facets of the Indian Hindu society as regards the education of mathematics to women – through an indirect exploration of their names. We also show that the pervasive occurrence of these names is not merely the result of semantic chance events, but denotes the richness of the Indian mathematical legacy. Next, we also present cross-cultural comparisons to show the uniqueness of Indian mathematical and scientific traditions that led to the pervasiveness of ‘mathematical names’ in India. Finally, an attempt is made to clarify some subtle points on the associations between mathematics and religion in India and other cultures of the world. It is sincerely hoped that the present study may shed light on the cultural roots of mathematics and may furnish a new dimension in the study of mathematics, culture and civilizations across the world.
Social Media as a Civic Mobilizer: Community Storytelling Network, Social Media, and Civic Engagement in South Korea

ABSTRACT This study advances communication infrastructure theory by testing the effects of an integrated community storytelling network (ICSN) and social media as a newly emerging community storytelling agent on civic engagement. A nationwide survey in South Korea indicates that, while ICSN is a robust driving force for civic engagement, social media news use and social media news expression played a vital role in promoting collective efficacy as well as neighborhood belonging and online civic participation, respectively. In particular, social media news use moderated the effects of ICSN on offline and online civic participation. These findings suggest that social media as an emerging storytelling network in the CIT framework can play distinct yet selective roles in predicting civic engagement.
Levels of Crude Proteins and Some Inorganic Elements in Selected Green Vegetables of Dar es Salaam

Eight green vegetables commonly grown in Dar es Salaam were analyzed for their contents of crude proteins, 4 macro minerals (Mg, K, Ca and Na) and 7 heavy metals (Pb, Cd, Zn, Cu, Mn, Cr and Fe). The values of crude proteins ranged between 1.03-5.23% on fresh weight. These vegetables were found to be rich in macro minerals. The levels of Pb and Cd in some vegetables were above the permissible limits recommended by FAO/WHO. Overall data have, however, indicated that consumption of these vegetables is unlikely to pose any health hazard to the consumer, as these vegetables are good sources of some other essential elements.
New Turner-Fairbank Alkali-Silica Reaction Susceptibility Test for Aggregate Evaluation

The ASTM C1260 and ASTM C1293 are generally accepted as being the best available accelerated tests to evaluate the alkali-silica reactivity of aggregates used in concrete. Unfortunately, these tests have limitations, such as the significant amount of false-positive and false-negative results in ASTM C1260 and the alkali leaching in ASTM C1293, that reduce their accuracy. This paper introduces an alternative test method, the Turner-Fairbank alkali-silica reaction (ASR) susceptibility test (T-FAST) that overcomes traditional limitations of both ASTM standards. In the new test, the ASR was accelerated by exposing the aggregates to a 1 N NaOH solution, three different amounts of CaO, and two temperatures for 21 days. The reactivity index (RI), calculated based on the 21-day concentrations of aluminum, calcium, and silicon in liquid phase, was used to assess the alkali-silica reactivity of 24 well-known aggregates—17 coarse and 7 fine. The results agreed with the classification of the same based on ASTM C1293 and historic field performance available in the literature. The alkali levels at which the ASR reaction was triggered in a selection of aggregates were measured using the T-FAST experimental set up. The threshold alkali values obtained matched those previously reported using accelerated concrete expansion tests as well as with concrete blocks in outdoor exposure sites. The alkali threshold determined for a river sand from Arkansas helped to understand the unexpected ASR distress observed in the field for an aggregate traditionally categorized as nonreactive. This case is a good example of mismatch between the information obtained from accelerated-ASR standard tests and field performance.

The tensile strength of bleached mechanical pulps from the Mg(OH)2-based and NaOH-based peroxide bleaching processes

De la pâte chimico-thermomecanique (PCTM) d'erable, de la pâte mecanique sous pression (PMSP) d'erable et de la pâte thermomecanique (PTM) d'epinette a divers indices d'egouttage ont ete blanchies au peroxyde a l'aide de Mg(OH) 2 ou de NaOH comme source d'alcali. La resistance a la traction de la PTM d'epinette est demeuree inchangee ou a diminue legerement lors du blanchiment au peroxyde a base de Mg(OH) 2 . Quant au blanchiment au peroxyde a base de NaOH, les proprietes de resistance de la PTMd'epinette blanchie ont ete fonction de la charge d'alcali. Pour la PMSP et la PCTM d'erable, le blanchiment au peroxyde a base de Mg(OH) 2 et le blanchiment au peroxyde a base de NaOH ont produit des pâtes blanchies possedant des proprietes de resistance plus elevees que les pâtes ecrues, l'effet etant plus prononce lors du blanchiment a base de NaOH. Les resultats de la spectroscopie ESCA soutiennent la conclusion qu'une acidification survenant apres le blanchiment occasionne la redeposition de la lignine dissoute et des matieres extractives sur les fibres de pâte, ce qui entraine une diminution de la cohesion entre les fibres.
The Influence of Self-efficacy on Resilience in Students Who Work in Thesis

Students who are working on their final project often faced with various problems and pressures. They need to build self-efficacy to be able to increase confidence in achieving something. Self-efficacy is an individual’s belief in their ability to organize and take steps in solving certain problems or tasks. Individuals with high self-efficacy view difficult tasks as challenges to face rather than as threats to avoid. Respondents are highly committed to achieving its goals, respondents will also invest a high level of effort and strategic thinking to deal with failure. Resilience is the ability to thrive in the face of adversity in every individual whilst facing problems or pressure. By increasing resilience, humans can develop life skills such as communicating, realistic abilities in making life plans, and being able to take the right steps for their lives. This study was conducted to determine whether self-efficacy has an effect on resilience. The research design used in this study is a quantitative research design with a sample of 75 people and the population of this study is students who are working on a thesis. The data were first analysed for validity, reliability, and followed by simple regression analysis. The results showed that self-efficacy had an effect on the resilience of 30,5% and a significant value of p = . 000 (p<0.05), testing the effect of the dimensions of selfefficacy on resilience showed results that strength has the greatest influence on resilience.
