Adsorption Behavior of Acid-Treated Brazilian Palygorskite for Cationic and Anionic Dyes Removal from the Water

The effect of acid treatment on the adsorptive capacity of a Brazilian palygorskite to remove the crystal violet (CV) and congo red (CR) dyes was investigated. The raw palygorskite was acid-treated by different HCl solutions (2, 4, and 6 mol/L). The modifications on the palygorskite structure were investigated using X-ray diffraction, X-ray fluorescence, Fourier-transform infrared spectroscopy, N2 adsorption/desorption, and thermogravimetric and differential thermal analysis. The efficiency of CV and CR adsorption was investigated, and the effect of the initial concentration, contact time, pH, and adsorbent amount was analyzed. The results revealed that CV adsorption in the acid-treated palygorskite was higher than that of the raw material. A Langmuir isotherm model was observed for the adsorption behavior of CV, while a Freundlich isotherm model was verified for the CR adsorption. A pseudo-second-order model was observed for the adsorption kinetics of both dyes. The higher CV adsorption capacity was observed at basic pH, higher than 97%, and the higher CR removal was observed at acidic pH, higher than 50%. The adsorption parameters of enthalpy (ΔH), entropy (ΔS), and Gibbs energy (ΔG) were evaluated. The adsorption process of the CV and CR dyes on the raw and acid-treated Brazilian palygorskite was predominantly endothermic and occurred spontaneously. The studied raw palygorskite has a mild-adsorption capacity to remove anionic dyes, while acid-treated samples effectively remove cationic dyes.
Green Building Adoption on Office Markets in Europe: An Empirical Investigation into LEED Certification

The goal of the paper is to evaluate the impact of selected factors on the adoption of LEED (Leadership in Energy and Environmental Design) green building certification in Europe. In the empirical part of the paper we track the fraction of LEED-registered office space in selected European cities, and assess the impact of selected socioeconomic and environmental factors on the certification adoption rate. This research contributes to the ongoing debate about the adoption of green buildings in commercial property markets. In this paper, we investigate factors affecting the adoption of LEED certification using the Arellano and Bond generalized method-of-moments estimator. Compared to prior studies, which relied on cross-sectional data, our research uses a panel approach to investigate the changes in green building adoption rates in selected European cities. Among the cities that are quickly adopting LEED are Frankfurt, Warsaw, Stockholm, and Dublin. The adoption process was not equally fast in Brussels and Copenhagen. Using the dynamic panel model approach, we found that the adoption of green building certification is linked to overall innovativeness in the economy and the perceived greenness of the city. Contrary to some previous studies we did not observe links between the size of the office market and the LEED adoption rate.
Effects of Plant Density and Row Spacing on Yield and Yield Components of Peanut (Arachis hypogaea L.) on the Coastal Sandy Land Area in Nghe An Province, Vietnam

Background: Understanding the effects of different plant densities and row spacing on yield and yield components of peanut L14 is essential for designing and adjusting management practices to improve yield. Methods: Five planting densities were tested in Randomized Complete Block Design with three replications in 2019 spring crop on the coastal sandy land area in Dien Chau district, Nghe An, Vietnam. Result: The different density treatments affect the growth, development and yield of the peanut variety L14. With increasing plant density, the number of pod per plant, 100 pods weight, 100 seeds weight decreased, whereas plant height, leaf area index, dry matter production increased. Population yield increased with increasing plant density from the lowest density of 25 plants m-2 (2.78 tons ha-1), reached the highest at 35 plants m-2 (4.53 tons ha-1), then decreasing with increasing plant density. Peanut variety L14 is grown in plant densities and row spacing of 35 plants m-2 (25 cm × 25 cm) and 40 plants m-2 (25 cm × 20 cm) are most appropriate; plants grow, develop better and give a higher yield than other densities under the same conditions.
Bionomics of slender burnished brass (Thysanoplusia orichalcea [Fabricius, 1775], Lepidoptera: Noctuidae) on potato (Solanum tuberosum L.) in Kashmir

A study on biology, morphometrics and geometrical progression of Thysanoplusia orichalcea was conducted on Solanum tuberosumunder laboratory conditions. Different stages viz., egg, larva, pupa and adult of T. orichalcea were observed for their duration and morphometric measurements. The pest depicted five larval instars and moultedfour times during the entire period. The average pre oviposition and oviposition period was observed to be 3.80 and 2.80 days respectively.Further, fecundity ranges between 381.0-400.0 with an average of 388.0 eggs. The mean incubation period was found to be 4.2 days. The average larval, pre pupal and pupal period was completed in 23.1, 1.4 and 9.5 days respectively. While mean adult longevity on S. tuberosum was 7.45 days. The total life cycle was completed in 41.0-51.0 days with an average of 45.65 days. Moreover, mean head capsule width of first, second, third, fourth and fifth larval instar was found to be 0.33, 0.54, 0.88, 1.46 and 2.24 mm respectivelywith Dyar’s ratio/ growth ratio of 1.63 mm. The expected head capsule width of first, second, third, fourth and fifth larval instar wasobserved as 0.33, 0.53, 0.86, 1.40 and 2.28 mm respectively.
STEM Learning Environment: Perceptions and Implementation Skills in Prospective Science Teachers

The STEM learning environment is the practice of students’ class solving problems. They use two or more STEM disciplines to solve the problem. The study aims to analyze the perceptions and implementation skills of the STEM learning environment in science education students before and after teaching internships. Perceptions and implementation skills of STEM in prospective teachers or initiatives about STEM are essential in shaping prospective teachers’ characters in facilitating their students as the 21st-century generation. This research used a qualitative approach with descriptive statistical analysis. The data had been retrieved since 2019, then in 2020 after teaching internship. The total of students in this study was 86 from the 2018 class. The students came from three Islamic State Universities in Indonesia. Data collection was carried out through interviews, surveys, and pictures of perceptions and the implementation skill of STEM. The STEM learning environment instruments used were based on integration, personal experience, realistic problems, multiple representation, collaboration, student-centered instruction, and the engineering design process. The results of this study indicated that there is a significant increase in the perception and implementation skill of the STEM learning environment in science education students after teaching internship, indicated by the result of the paired sample t-test were the Asymp Sig. α<5 for each indicator. Perceptions and skills of implementing STEM learning environments in students’ science education increased from before and after the teaching internship. It shows that the curriculum of the science education study program must be designed with a STEM learning environment approach to have good teaching skills. Curriculum design that leads to increased understanding has pedagogic and professional courses, especially pedagogical courses which include strategic subjects, learning models, learning media, and learning tools.
The Influence of Leadership Style on Managerial Performance of Village Governments with Motivation as Mediation

This study aims to understand the leadership style’s influence on the village government’s managerial performance with motivation as mediation. This test used the village government’s managerial performance as the dependent variable, transactional leadership style and transformational leadership style as independent variables, and motivation as a mediating variable. The sample employed was the village government apparatus in Sleman Regency, Indonesia, utilizing a convenience sampling method. The data type used in this study was the primary data. Based on the distributing questionnaires’ process obtained a sample of 102 respondents. Hypothesis testing in this study employed simple regression and multiple regression using SPSS v.15 software applications. The results showed that transactional leadership style, transformational leadership style, and motivation positively influenced the village government’s managerial performance. Meanwhile, motivation could not mediate the relationship between leadership style and managerial performance.
Computational approaches to fragment based screening

Polarization is an often - neglected term in molecular modelling, and this is particularly the case in docking. However, the growing interest in fragment - based drug design, coupled with the small size of fragments that makes them amenable to quantum mechanical treatment, has created new opportunities for including polarization, anisotropic electrostatics and realistic repulsion potentials in docking. We have shown that polarization implemented as induced charges can offer in the region of a 10-15% improvement in native docking results, as judged by the percentage of poses within a rather tight threshold of 0.5 or 1.0 A, where accurate prediction of binding interactions, are more likely. This is a significant improvement given the quality of current commercial docking programs (such as Glide use d here). This improvement is most apparent when the correct pose is known a priori, so that the extent of polarization is correctly modelled, and scoring is based on force - fields that do not scale the electrostatics. The introduction of specific active - sit e water molecules was shown to have a far greater effect than the polarization, probably because of the introduction of 3 additional full charges, rather than introduction of smaller charge perturbations. With active site waters , polarization is more likely to improve the docking when the water molecule is carefully orientated using quantum mechanical/molecular mechanics (QM/MM) methods. The placement of such water molecules is a matter of great current interest; we have shown that the water molecule can be placed with some degree of reliability simply by docking with the ligand present, provided that the water makes good hydrogen bonding interactions (these are the very conditions under which it is desirable to include the specific active-site water). Anisotropic electrostatics and exponential repulsion for rigid fragments was investigated using Orient and compared to QM/MM methods, all methods merited further research. The general hierarchy is that native docking using Glide (with polarization)> QM/MM (with MM polarization)> Orient-based methods. Thus, we expanded the Glide (with polarization) dataset to include more realistic crossdocking experiments on over 5000 structures. RMSD analysis resulted in many examples of clear improvement for including polarization.
Assessment of soil degradation through soil aggregation and particulate organic matter following conversion of riparian buffer to continuous cultivation

Agriculture in the temperate zone of the Midwestern USA has removed most riparian buffer zones from the landscape, which impairs the soil functioning of the soil in these ecosystems. The objective of this study was to assess soil degradation in a non‐buffered riparian zone with an annual row crop (ARC) and in a longer established (more than 85 years) riparian cool season grass (CSG) buffer in central Iowa, USA. To achieve our objective, we compared the functioning of the target system, ARC, with a system that has been undisturbed since 1990, CSG. We measured the aggregate size distribution and stability of macroaggregrates, aggregate‐associated soil organic carbon and particulate organic matter (POM). The categorization of aggregates by size and water stability (slaking resistance) showed a significantly larger (P < 0.05) proportion of water‐stable macroaggregates (> 250 µm) under CSG (53%) than under ARC (26.3%). On the other hand, soil under ARC had the larger proportion of large and small water‐unstable macroaggregates. The results indicate that the concentration of organic C associated with the total water‐stable aggregates is 1.9 times greater under CSG (23.9 mg C g−1) than for the ARC (12.4 mg C g−1). The concentration of carbon in light particulate organic matter (LPOM‐C) under CSG accounted for 12% of total soil organic carbon (TSOC), but only 6% under ARC management. The chemical composition of LPOM in the ARC soil had a large alkyl‐C/O‐alkyl C ratio, which suggests more organic matter decomposition than with the CSG. Electronic micrographs showed evidence that under CSG roots and fungal hyphae form an extensive network around the large macroaggregates (> 2000 µm), and thus maintain the stability of the macroaggregates. Preserving the CSG buffer reduces soil erosion and the processes associated with nonpoint source pollutants, which improves water quality in an intensively managed agricultural system.
The potential role of S-allylcysteine as antioxidant against various disorders in animal models

Successful regulation of cellular equilibrium among oxidation and anti-oxidation is significant for cellular function and DNA integrity as well as gene expression for signal transduction. Numerous pathological processes, such as cancer, diabetes, heart and/or kidney diseases, ParkinsonÂs and AlzheimerÂs diseases, have been revealed to be associated to the redox state of cells. In a challenge to curtail the onset of oxidative stress, administration with diverse recognized antioxidants has been recommended. Glutathione (GSH) is accepted for its capability to reduce oxidative stress and downstream the harmful effects such as lipid peroxidation. Antioxidants thus play a significant part in protecting the human body against the damage caused by reactive oxygen species. S-Allylcysteine (SAC), a sulfur containing amino acid derived from garlic, has been experimentally demonstrated to possess antioxidant and other beneficial activities. In the present review, we addressed the therapeutic effects of SAC as a potential antioxidant on various disorders by increasing GSH and other antioxidants. Authenticated with a number of in vivo, in vitro, animal experiments and some human clinical trials, beneficial effects of SAC were reported in cancer, neurodegeneration, nephrotoxicity, ischemic stroke, myocardial infarction and other heart diseases, AlzheimerÂs disease, ParkinsonÂs disease, preeclampsia and diabetes mellitus. On the other hand, there is no scientific evidence against SAC for having adverse effects.
THE ROLE OF COMPANY REPUTATION IN MITIGATING NEGATIVE WORD OF MOUTH

The study aims to investigate whether a company reputation can be used to reduce the impact of negative electronic word of mouth (eWOM). We conducted experimental research in two studies along with 225 college students, who at least have two accounts in different social media, as participants. We use both qualitative and quantitative methodologies. Qualitative research was carried out with focus group interviews to decide the number of high or low negative reviews as well as the level of credibility. Quantitative research used cross-sectional field design by pilot study and the main study. The model was tested and developed using data collected by questionnaires in paper surveys. The results of study 1 suggest that negative eWOM reduces purchase intentions mediated by the subjective norms and perceived behavior control. High negative eWOM reduces purchase intention more than low ones. Study 2 found out that in a condition of high negative eWOM, good company reputation’s perception affected purchase intention mediated by attitude. Furthermore, purchase intention is higher when a good company reputation’s perception is stronger. Therefor Organizations should convey its company reputation to their customer visually to get a good perception. Further research to investigate another variable that the company has is required.
Scale Evaluation and Eligibility Determination of a Field-Test Version of the Assessment, Evaluation, and Programming System–Third Edition

Rasch and classification analyses on a field-test version of the third edition of the Assessment, Evaluation, and Programming System (AEPS-3), a curriculum-based assessment used to assess young children birth to age 6 years, were conducted. First, an evaluation of the psychometric properties of data from each developmental area of an AEPS-3 field-test version was conducted. Next, cutoff scores at 6-month age intervals were created and then the validity of the cutoff scores was evaluated. Results using Rasch modeling indicated acceptable model fit statistics with reasonable reliability estimates within each developmental area. Classification results showed cutoff scores accurately classified a high percentage of eligible children. Findings suggest that scores from a field-test version of the AEPS-3 are reliable within developmental areas. To the extent allowed by state criteria, early childhood interventionists could possibly use a new field-test version of the AEPS-3 to determine or corroborate eligibility for special education services.
Different Leaders in a COVID-19 Scenario: CEO Altruism and Generous Discourse

Academic literature has begun to be interested in the informational gaps between what companies say and do in relation to their financial performance and their commitment to society and the environment, identifying the use of self-protection and self-enhancement strategies before their interest groups. In this research, based on a statistical analysis of textual data and a correspondence analysis, the sentiment of the discourse that Spanish CEOs have held with their stakeholders regarding the operational and strategic decisions they made in the face of COVID-19 is analysed. The evidence shows that managers who promptly reported negative news regarding divestments, cutting expenses and destroying jobs, used the epidemic as justification. The leaders who combined these decisions with responsible actions—focused on the ethical and commercial sustainable dimensions—adopted an approach with a different degree of self-enhancement to value their responsible decisions. In contrast, optimistic CEOs, altruistically committed to society, opted for more personal, emotional, dynamic and constant channels and procedures, avoiding selfish attributions for their actions.
A Deferasirox Derivative That Acts as a Multifaceted Platform for the Detection and Quantification of Fe3+

Here, we report that ExSO3H, a synthetically accessible, water-soluble, non-toxic derivative of the clinical iron chelator deferasirox, acts as a colorimetric chemosensor that permits the detection and quantification of Fe3+ in aqueous samples at pH 2–5. In addition, we observed that a fluorescent turn-on response was produced when this chelator was allowed to interact with human serum albumin (HSA). This fluorescence was quenched in the presence of Fe3+, thus allowing us to monitor the presence of this biologically important metal cation via two independent methods.
When #BlackLivesMatter at the Women’s March: a study of the emotional influence of racial appeals on Instagram

ABSTRACT Protestors often carry signs expressing their support or opposition to political issues. In recent years, people often take pictures holding their protests signs and post these images to social media platforms like Instagram. “Black Lives Matter” has become a common and controversial refrain used on protest images online. Black protestors as well as white protestors have posted images holding signs that say “Black Lives Matter. ” In this study, I use experimental methods to explore how exposure to Instagram posts that vary the race of the protestor as well as the message on the protester’s sign influence white people’s emotional responses to political messages. I make use of new media to demonstrate the ways in which white guilt remains a powerful mobilizing tool in the era of social media. Using data from Amazon’s Mechanical Turk, I conduct sentiment analysis of open-ended survey responses to explore the role of emotions in the process of political agenda setting. I find that when racial appeals elicit white guilt, they motivate support for identifying racism as an important issue in this country. However, when racial appeals elicit feelings of annoyance or irritation white respondents are significantly less likely to identify racism as an important issue.
Electrochemical Determination of Ascorbic Acid Based on Hydrothermal Synthesized ZnO Nanoparticles

In this work, ZnO nanoparticles (NPs) were prepared through an easy one-pot hydrothermal method. After synthesis, the obtained ZnO NPs were successfully adopted for surface modification of a glassy carbon electrode (GCE). The GCE modified with ZnO NPs was utilized to detect ascorbic acid (AA) in a sensitive and selective way. The biosensor revealed a linear correlation with AA concentration in the range of 1-800 μM, with a limit of detection of 0.312 μM (S/N = 3). The presented AA sensor manifested outstanding stability and repeatability and an anti-interference nature.
National identity exploration attenuates the identification–prejudice link

Social identity exploration is a process whereby individuals actively seek information about their group membership and show efforts to understand its meaning. Developmental theory argues that exploration-based ingroup commitment is the basis for outgroup positivity. We tested this notion in relation to national identity and attitudes towards immigrants. The results of five experimental studies among German adolescents and early adults (N = 1,146; 16–25 years) and one internal meta-analysis suggest that the positive identification–prejudice link is weaker when participants are instructed to explore the meaning of their identity (Study 1). This is not mediated via self-uncertainty (Study 2), but via a reduction in intergroup threat (Study 3) and an increase in deprovincialization (Study 4). In addition, identity exploration enabled strong identifiers to oppose descriptive ingroup norms (Study 5). We conclude that identity exploration can contribute to a further understanding of the identification–prejudice link.
Studying the Urban Heat Island Usinga Local Climate Zone Scheme

With rapid urbanization and the rise of climate change awareness, policy makers and urban planners are seeking methods and schemes that consider the urban heat island (UHI) effect. In order to investigate to what extent a homogeneous urban fabric leads to a specific thermal pattern, a local climate zone (LCZ) scheme was utilized and classification has been applied in the urban areas of Chongqing. Urban indicators were calculated to match LCZ types of measurement points. Using a mobile measurement approach, we analyzed screen-height air temperature distribution inside local climate zones in both spring and summer. An apparent seasonal difference inside LCZs was found, with air temperature amplitude about 0.8oC in spring and 0.9oC in summer. The average air temperature difference in LCZ 1 was 2.9oC between the two seasons, while in LCZ H this difference was as high as 3.5oC. The reasons why LCZ H had relatively high air temperature were explained and further investigation of UHI using LCZ scheme was proposed.
