Green Synthesis, SC-XRD, Non-Covalent Interactive Potential and Electronic Communication via DFT Exploration of Pyridine-Based Hydrazone

Ultrasound-based synthesis at room temperature produces valuable compounds greener and safer than most other methods. This study presents the sonochemical fabrication and characterization of a pyridine-based halogenated hydrazone, (E)-2-((6-chloropyridin-2-yl)oxy)-N′-(2-hydroxybenzylidene) acetohydrazide (HBPAH). The NMR spectroscopic technique was used to determine the structure, while SC-XRD confirmed its crystalline nature. Our structural studies revealed that strong, inter-molecular attractive forces stabilize this crystalline organic compound. Moreover, the compound was optimized at the B3LYP/6-311G(d,p) level using the Crystallographic Information File (CIF). Natural bonding orbital (NBO) and natural population analysis (NPA) were performed at the same level using optimized geometry. Time-dependent density functional theory (DFT) was performed at the B3LYP/6-311G (d,p) method to calculate the frontier molecular orbitals (FMOs) and molecular electrostatic potential (MEP). The global reactivity descriptors were determined using HOMO and LUMO energy gaps. Theoretical calculations based on the Quantum Theory of Atoms in Molecules (QT-AIM) and Hirshfeld analyses identified the non-covalent and covalent interactions of the HBPAH compound. Consequently, QT-AIM and Hirshfeld analyses agree with experimental results.
A Systematic Literature Review on the Academic and Athletic Identities of Student-Athletes

Academic and athletic identities are related to performance and wellbeing indicators in both the educational and sport domains, respectively. This paper presents a systematic literature review examining empirical research into the academic and athletic identities of student-athletes in dual (education and sport) careers. The 42 records identified in this review suggest that research on the academic and athletic identities of student-athletes has focused on the themes of: identity development, role conflict, career development and motivation, and student-athlete stereotypes. Future research directions are considered, including the need for mixed-methods and longitudinal assessments of academic and athletic identities to assess to dynamic nature of identity development, and to ascertain how these relate to future performance and wellbeing outcomes.
Troubleshooting to Learn via Scaffolds: Effect on Students’ Ability and Cognitive Load in a Robotics Course

Studies have indicated the importance of scaffolding in the problem-solving process, as well as the potential of integrating learning content into the troubleshooting tasks. However, few have explored in depth the learning process during troubleshooting via scaffolds while also taking students' cognitive load into account. To address this issue, four kinds of scaffolds (with/without process information plus with/without solution) were set up during three learning phases (Introductory, Mastery, Applicable) in a robotics course. A total of 171 seventh graders participated in the course and learned by troubleshooting with different scaffolds. An experiment with 4 × 3 mixed design was employed to evaluate students' troubleshooting performance (higher-order ability), cognitive load and programming skill (lower-order ability). Across the three learning phases, the scaffold with process information while without solution, was always more effective for students’ higher-order ability compared to the other scaffolds. However, there was no significant difference in the low-order ability among the four scaffolds in the Applicable Phase. Results confirmed that the expertise-reversal effect of learning scaffold would appear in the students’ lower-order ability cultivation, but not the higher-order ability. This is a new finding for deeper insights into learning scaffolds with process information.
Prevalence of possible developmental coordination disorder among Grade 1 learners in low socio-economic environments in Mangaung, South Africa

Background: Developmental coordination disorder (DCD) affects motor skills and consequently has an impact on the performance in daily living activities of learners with this impairment.Aim: The aim of this study was to determine the prevalence of possible DCD in Grade 1 (Gr. 1) learners in a low socio-economic environment in Mangaung, South Africa.Setting: The study was conducted in the Mangaung Metro, Motheo District, Free State Province. Gr. 1 learners, 6–8 years old (n = 242), from a low socio-economic environment attending Quintile 1–3 schools were randomly selected for assessment.Methods: The Movement Assessment Battery for Children-2nd edition (MABC-2) was used to identify learners with possible DCD. Furthermore, results were compared with regard to gender.Results: Of the 242 learners, 9.9% were identified with possible DCD. With regard to gender, 10.5% of boys and 9.3% of girls showed signs of possible DCD. No significant difference (p = 0.9439) has been found between boys and girls.Conclusion: The prevalence of possible DCD among Gr. 1 learners in this setting was higher than that in previously reported studies in other low and high socio-economic environments of South Africa. Further research is required to establish the full extent of possible DCD within learners living in low socio-economic environments.

We administered a 39-question survey, including open-ended questions that were coded for qualitative analyses, to 2,853 students to delineate the scope of this problem and identify actionable solutions. The prevalence of food insecurity in this population is 28.5%, with one in five (21.3%) reporting lack of food impacting academic performance.
VALIDATION OF A BIOANALYTICAL REVERSE-PHASE HIGH-PERFORMANCE LIQUID CHROMATOGRAPHIC METHOD FOR THE QUANTITATION OF NYSTATIN IN AN ANIMAL MODEL AFTER INTRANASAL IN SITU GEL ADMINISTRATION

Objective: The aim of the study was to develop and validate a bioanalytical reverse-phase high-performance liquid chromatographic (HPLC) method for the estimation of nystatin in rat plasma after intranasal administration. Methods: The reversed-phase HPLC system was equipped with a Luna C18 column, the mobile system comprised of methanol, water, and dimethylformamide (55:30:15) and the flow rate was set at 0.9 ml/min. Results: The elution time for nystatin was 4.096±0.025 min. The calibration curves constructed in rat plasma were linear from 0.25 to 50 μg/ml. The lower limit of quantification (LOQ) was found to be 0.25 μg/ml. The standards for accuracy and precision of the intra- and inter-day variation studies were in the acceptable ranges as per the FDA guidelines. Conclusion: The LOQ value determined by the proposed method was noted to be satisfactory for inspecting the plasma pharmacokinetics of nystatin in rats’ post-administration of a nasal in situ gelling liquid crystalline precursor formulation in an in vivo study.
Joint effects of the liability network and portfolio overlapping on systemic financial risk: contagion and rescue

We examine the conjoined contagion mechanism of the inter-liability network and portfolio overlapping in shaping systemic financial risk. We first develop an iterative algorithm to compute the largest clearing payment vector and price vector, and prove its existence and continuity. A concrete form of total wealth loss is then derived to specify the joint effects of the inter-liability network and portfolio overlapping. Next, we show how inter-institutional liability connections and portfolio diversification can amplify the impact of initial negative shocks and lead later to financial crisis. We prove that illiquidity is a critical factor in triggering risk contagion and that higher inter-institutional leverage can cause larger losses for both the institutions and the outside obligees. Based on the theoretical findings, we propose a rescue strategy via solving a series of linear programs and conclude with some practical suggestions for the management of systemic financial risk.
Palaeogene stratigraphy and chronology of the western Sivas Basin, central Anatolia (Turkey): Tectono‐sedimentary evolution of a well‐preserved basin along the northern Neotethys suture zone

The Sivas Basin overlaps the northern Neotethys suture zone in central Anatolia (Turkey) and contains a ca. 12‐km thick succession of Cenozoic strata that provides an exceptional record of major tectonic transitions from subduction to continental assembly and tectonic escape. Consensus regarding the tectonic and palaeogeographic evolution of this segment of the Arabia‐Eurasia collision zone has been hindered by uncertainty in the tectonic setting of the early (Palaeogene) Sivas Basin, which has been variably interpreted as a remnant ocean, forearc, foreland, wedge‐top or intracontinental extensional basin. Here we integrate new geologic mapping (>5,000 km2), stratigraphy, facies analysis and U‐Pb geochronology from the western Sivas Basin to produce a detailed time‐stratigraphic framework and a refined Palaeogene tectono‐sedimentary model for the Sivas Basin. Earliest marine sedimentation occurred during the Maastrichtian‐Palaeocene in a remnant ocean setting due to incomplete closure of the northern Neotethys Ocean. Rapid accumulation of >2 km of basin floor turbidites during the middle to late Eocene reflect a transition to a foreland setting. A major late Eocene unconformity (ca. 38–34 Ma) coincides with the initiation of the north‐vergent southern Sivas fold‐thrust belt, which inverted and structurally partitioned the basin into a southern wedge‐top and a northern evaporitic foreland basin; the entire basin was dominantly nonmarine after this unconformity. Published palaeomagnetic data integrated with a newly discovered tuff dated at 31.9 Ma reveal that the 2.8‐km thick Altinyayla Formation was deposited from ca. 34 to 26 Ma in an unconfined braided fluvial system. Close stratigraphic correlations between the western, central and northern Sivas Basin suggest that the entire basin evolved from a remnant ocean to peripheral retro‐foreland basin during the middle to late Eocene, and finally a fragmented foreland basin since the Oligocene. This general evolution may be a characteristic of such sedimentary basins formed on suture zones across Anatolia and in other collisional orogens globally.
Physiological and Biochemical Basis of Faba Bean Breeding for Drought Adaptation—A Review

Grain legumes are commonly used for food and feed all over the world and are the main source of protein for over a billion people worldwide, but their production is at risk from climate change. Water deficit and heat stress both significantly reduce the yield of grain legumes, and the faba bean is considered particularly susceptible. The genetic improvement of faba bean for drought adaptation (water deficit tolerance) by conventional methods and molecular breeding is time-consuming and laborious, since it depends mainly on selection and adaptation in multiple sites. The lack of high-throughput screening methodology and low heritability of advantageous traits under environmental stress challenge breeding progress. Alternatively, selection based on secondary characters in a controlled environment followed by field trials is successful in some crops, including faba beans. In general, measured features related to drought adaptation are shoot and root morphology, stomatal characteristics, osmotic adjustment and the efficiency of water use. Here, we focus on the current knowledge of biochemical and physiological markers for legume improvement that can be incorporated into faba bean breeding programs for drought adaptation.
Effects of heat stress on growth, photosynthetic pigments, oxidative damage and competitive capacity of three submerged macrophytes

ABSTRACT There is an information gap regarding heat stress-induced oxidative damage and the species-specific behavior of plants under stress conditions. The present study was designed with the hypothesis that heat stress may induce species-specific oxidative damage that determines the competitive capacity of common submerged macrophytes. We conducted two laboratory experiments to simulate mono- and mixed cultures of three submerged macrophytes with the application of two heat shock treatments. The results showed that both heat shocks had significant effects on growth, photosynthetic pigments and the ability to induce strong oxidative damage for all three species. The comparative results of mono- and mixed cultures showed that P. crispus had an advantage in both the control and high-temperature treatments over the other two species as a strong competitor in the mixed culture. Further, the competitive capacity of P. crispus increased in the moderately high-temperature condition compared to the control.

Variation in essential oil composition of coriander (Coriandrum sativum L.) varieties cultivated in two different ecologies

Abstract Coriander, Coriandrum sativum L, is an important medicinal plant belonging to Apiaceae family, which is grown in many parts of Turkey. In this study, essential oil and composition of 6 Turkish coriander cultivars (Gamze, Arslan, Erbaa, Pelmus, Kudret, Gürbüz) were examined in two different (Mardin and Tokat) ecologies. Essential oils were isolated with distillation method in maturated fruits and component composition was determined with gas chromatography–mass spectrometry (GC-MS). Main component was linalool in all cultivar, and it was higher in the conditions of Mardin having a warmer climate in all the cultivars than that of Tokat with temperate climate. Contrary to linalool, α-pinene and neryl acetate contents of all cultivar were higher in Tokat.
The Body Design of Hagfishes (Eptatretus stoutii and Myxine glutinosa) Protects from Biting Predators

The Body Design of Hagfishes (Eptatretus stoutii and Myxine glutinosa) Protects from Biting Predators Sarah Boggett Advisors: University of Guelph, 2017 Dr. D. S. Fudge Dr. P. A. Wright This thesis investigates how the body structure of hagfishes plays a role in defence against biting predators. Evidence of hagfish being attacked by biting predators show them swimming away relatively unscathed even after a violent initial attack. I hypothesized that the flaccid and loose body design of hagfishes protects them from biting predators by the minimal attachments between the skin and musculature combined with a large subcutaneous sinus allowing its internal organs to avoid damage from penetrating teeth. To test this, I quantified the flaccidity of the subcutaneous sinus, simulated shark attacks with a customized guillotine, and manipulated the adhesion and flaccidity between the skin and body of hagfishes and lamprey. Here I provide evidence consistent with my hypothesis. This ability of hagfishes to survive initial attacks from biting predators may be an essential component of a strategy that relies on defensive slime to thwart further attacks.
Structured Teaching and the Play of Preschoolers With Developmental Disabilities: An Evaluation

Play represents an important component of early childhood education and is linked to the development of communication and social skills, particularly for children with developmental disabilities who often lack play skills. Structured teaching is a systematic method that entails visually arranging and organizing the learning environment. Although effective for older individuals with disabilities, research examining the efficacy of structured teaching in increasing the play skills of young children is limited. This study examined the effects of structured teaching on the appropriate play of five preschool-age children with developmental disabilities. Results suggest structured teaching produced a higher level of play for two of the participants; however, gains were generally not maintained following discontinuation of the instruction. Findings, though mixed, have implications for practice and future research.

The effects of university research and teaching climate strength on faculty self-reported teaching performance

ABSTRACT In the university setting, faculty must engage in multiple job duties such as research and teaching. Devoting one’s time and effort to teaching or research is not only dependent on individual differences in teaching dedication, but also the university’s research and teaching climate strengths. Using organizational climate and person-situation interaction theories, we examined how interactions between university faculty teaching dedication and distinct university research and teaching climate strengths affect self-reported teaching performance. Multilevel analyses were conducted with 191 full-time College of Business faculty nested within 45 public universities. Results suggest that the interaction effect between teaching dedication and research climate strength on self-reported teaching performance supports the proposition that a weak organizational climate strengthens the relationship between teaching dedication and self-reported teaching performance. Specifically, the positive relationship between teaching dedication and self-reported teaching performance was amplified in a weak research climate compared to a strong research climate. Surprisingly, however, a strong teaching climate strengthened rather than attenuated the relationship between teaching dedication and self-reported teaching performance. Implications for how the results of this study might affect university recruitment and selection of faculty are discussed.
The Impact of the COVID-19 Pandemic on User Experience with Online Education Platforms in China

During the COVID-19 pandemic, social education has shifted from face to face to online in order to avoid large gatherings and crowds for blocking the transmission of the virus. To analyze the impact of virus on user experience and deeply retrieve users’ requirements, this paper constructs a reasonable evaluation index system through obtaining user reviews about seven major online education platforms before and after the outbreak of COVID-19, and by combining the emotional analysis, hot mining technology, as well as relevant literature. At the same time, the variation coefficient method is chosen to weigh each index based on the difference of index values. Furthermore, this paper adopts the comprehensive evaluation method to analyze user experience before and after the outbreak of COVID-19, and finally finds out the change of users’ concerns regarding the online education platform. In terms of access speed, reliability, timely transmission technology of video information, course management, communication and interaction, and learning and technical support, this paper explores the supporting abilities and response levels of online education platforms during COVID-19, and puts forward corresponding measures to improve how these platforms function.
