Evaluation of Sand Filtration and Activated Carbon Adsorption for the Post-Treatment of a Secondary Biologically-Treated Fungicide-Containing Wastewater from Fruit-Packing Industries

In this work, a sand filtration-activated carbon adsorption system was evaluated to remove the fungicide content of a biologically treated effluent. The purification process was mainly carried out in the activated carbon column, while sand filtration slightly contributed to the improvement of the pollutant parameters. The tertiary treatment system, which operated under the batch mode for 25 bed volumes, resulted in total and soluble COD removal efficiencies of 76.5 ± 1.5% and 88.2 ± 1.3%, respectively, detecting total COD concentrations below 50 mg/L in the permeate of the activated carbon column. A significant pH increase and a respective electrical conductivity (EC) decrease also occurred after activated carbon adsorption. The total and ammonium nitrogen significantly decreased, with determined concentrations of 2.44 ± 0.02 mg/L and 0.93 ± 0.19 mg/L, respectively, in the activated carbon permeate. Despite that, the initial imazalil concentration was greater than that of the fludioxonil in the biologically treated effluent (i.e., 41.26 ± 0.04 mg/L versus 7.35 ± 0.43 mg/L, respectively). The imazalil was completely removed after activated carbon adsorption, while a residual concentration of fludioxonil was detected. Activated carbon treatment significantly detoxified the biologically treated fungicide-containing effluent, increasing the germination index by 47% in the undiluted wastewater or by 68% after 1:1 v/v dilution.
Analysis of the earnings management methods of China’s electric power companies based on modified Jones model

With the constant revision of accounting standards, the earnings management methods are constantly changed and innovated in order to achieve the purpose of beautifying the statements and manipulating profits. This paper took the electricity listed companies as the research object, selected the financial data of 52 listed companies in the Shanghai Stock Exchange and the Shenzhen Stock Exchange from 2014 to 2016 as the sample, and employed the SPSS statistics software to analyze the earnings management methods of the listed companies in the electric power industry and to draw the conclusions through empirical research. Based on the preliminary statistical analysis of the earnings management methods of listed companies in the electric power industry, this paper used the modified Jones model to verify the empirical analysis. The main conclusions of this paper are as follows: There is a positive linear relationship between fixed assets management, assets impairment management and discretional accruals of the listed companies in the electric power industry. The degree of its influence is more obvious and stable than that of other earnings management methods, and passed the significance test. The collinear diagnostics can also prove a more reasonable correlation among the variables, indicating that the results obtained from the modified Jones model is more significant.
Post-Disaster Distribution System Restoration With Logistics Support and Geographical Characteristics

Repair scheduling and routing and logistics support are interdependent and critical for post-disaster distribution system restoration (PDSR), which is also influenced by the geographical characteristics of outage area. Hence, we develop a co-optimization model for the PDSR with logistics support and geographical characteristics. A hybrid improved bacterial colony chemotaxis algorithm is proposed to solve the model, in which A* algorithm is employed to route repair crews and material delivery in the transportation network considering geographical characteristics, and an improved bacterial colony chemotaxis algorithm is proposed to determine the repair scheduling and material allocation in the distribution system. Different scale of distribution system instances with different damage levels and different geographical characteristics are used to demonstrate the effectiveness of the proposed methodology.
IN SILICO MOLECULAR MODELING AND DOCKING STUDIES OF HERBAL COMPOUND MEDIATED INHIBITION OF Κβ KINASEβ (INHIBITOR OF Κβ KINASE SUBUNIT β) FOR OSTEOARTHRITIS TREATMENT

Objective: This study was intended to investigate and characterize the phytoconstituents of plant herbs and inhibitors, evaluate its anti-osteoarthritis (OA) and anti-inflammatory potential under in silico conditions. Methods: Docking studies were performed to find out the maximum interaction between design ligands and selected five proteins using Schrodinger Software NY. Structures of selected proteins were downloaded from protein data bank. Results: Morin, salubrinal, icariin, and chondroitin sulfate, and sesamol have higher binding energy than other compounds. Based on these properties out of 9 compounds we have selected 5 best-docked and compounds selected were molecular dynamics simulation with inhibitor of κβ kinase subunit (IKK) β. Arg20, Leu21, Thr23, Lys44, Glu61, Glu97, Cys99, Lys106, Asp145, Asn150, andAsp166 were actively involved in H-bond interaction with ligands. Each compound has different binding modes, which reflects the difference of interacting residues with different functional groups. Morin has better interaction than other compounds. Either Cys99 or Lys44 found predominantly in most of the complex except in β-ecdysterone whereas both found interacting with morin. Conclusion: The results revealed out that the herbal compounds can inhibit the IKKβ protein. The virtual screening yielded five potential IKKβ inhibitors: Morin, salubrinal, icariin, and chondroitin sulfate, and sesamol. This inhibitor shows good interaction, energy, and pharmacophoric activity and will be suitable for further experiments of an anti-OA target.
Co-creation of knowledge – an effective mechanism for managing decommissioning stakeholders

Despite the fact that it has been 26 years since the events of Brent Spar, stakeholder impacts are still continuing to affect the performance of oil and gas decommissioning projects. If stakeholders are not well managed, not only can they have devastating consequences on project costs and schedules, but there may also be further social and environmental implications as well. On the flip side, if organisations can get it right, stakeholders can also bring about various benefits. An ongoing research project to enhance project managers’ understanding of the United Kingdom and Australian decommissioning landscapes found that knowledge creation through interactions between organisations and stakeholders has brought about benefits to various decommissioning projects, including the Maureen, Miller, and Brae decommissioning projects. The concept of co-creation of knowledge has been mentioned in many academic works to be an effective mechanism for managing stakeholders in the field of sustainable development, product development, and healthcare. However, the explicit links between co-creation of knowledge and decommissioning have yet to be drawn. This article proposes that co-creation of knowledge be adopted as a best practice to manage decommissioning stakeholders. By actively co-creating knowledge with stakeholders and extending the existing body of knowledge in decommissioning, the extent of alignment and trust between organisations and stakeholders are strengthened, creating long-term relationships that greatly improves the probability of stakeholder acceptance and approval.
Quality of Life, Thyroid Function and Type of Surgery in Low Risk Thyroid Cancer

Background: Low risk thyroid cancer can be treated with lobectomy or total thyroidectomy. Studies have shown that the risk of recurrence does not differ between the two surgeries, although there are higher rates of complications with total thyroidectomy. Our study aimed to find if there were differences in quality of life and thyroid function in the two treatments. Methods: Low risk DTC survivors answered three QoL questionnaires (EQ5D3L, SF36, and EORTC QLQ C30) and had their thyroid function evaluated. Results: Twenty-six lobectomy patients and 101 total thyroidectomy were included. Hypoparathyroidism occurred more in the total thyroidectomy, and TSH was more likely to be on target (0.5-2.0) in lobectomy. There was no difference between groups regarding QoL, but there was a significant difference regarding thyroid function. In SF36 form, TSH off target led to more physical limitations, pain, less vitality, and worse social aspects. Abnormal total T3 level was associated with pain, less vitality, and worse mental health. In the EORTC QLQ C30, off target TSH led to worse role functioning, fatigue, and nausea. EQ5D form showed that worse utility index was found when TT3 was not in normal range. Conclusion: This study showed there was a difference among thyroid function, specially TSH depending on type of surgery. When uncontrolled, TSH was associated with worse aspects of the quality of life. Therefore, lobectomy patients have a better thyroid function control and less surgical complications which might have an impact in some aspects of the quality of life when compared to total thyroidectomy.
Theory of Ferromagnetism in Reduced ZrO2–x Nanoparticles

Bulk ZrO2 is both nonreducible and nonmagnetic. Recent experimental results show that dopant-free, oxygen-deficient ZrO2–x nanostructures exhibit a ferromagnetic behavior at room temperature (RT). Here, we provide a comprehensive theoretical foundation for the observed RT ferromagnetism of zirconia nanostructures. ZrO2 nanoparticles containing up to 700 atoms (3 nm) have been studied with the help of density functional theory. Oxygen vacancies in ZrO2 nanoparticles form more easily than in bulk zirconia and result in electrons trapped in 4d levels of low-coordinated Zr ions. Provided the number of these sites exceeds that of excess electrons, the resulting ground state is high spin and the ordering is ferromagnetic. The work provides a general basis to explain magnetism in intrinsically nonmagnetic oxides without the help of dopants.
Effects of fertilizer on growth and yield of red beans under competition conditions with Amaranthus retroflexus

Abstract In order to investigate the effect of organic and chemical fertilizers on the yield and some physiological traits of beans under conditions of competition with Amaranthus retroflexus, an experiment was performed in the form of slip plots as a complete randomized block design (RCBD) with three replications. The experimental treatments included three densities of Amaranthus retroflexus as the main factor and fertilizer at five levels as the sub-factor. The results showed that the amount of weed nitrogen, ranging from the highest to the lowest, under the intense competitive pressure of Amaranthus retroflexus (D3 = 14) was related to nitrogen (85.08%), biochar (65.78%), compost (19.51%) and manure (16.44%) fertilizer, respectively. The results of this experiment indicated that the negative impact of wild Amaranthus retroflexus competition on grain yield depends on the type of fertilization and weed density of Amaranthus retroflexus. Among all fertilization treatments, at high competitive density of Amaranthus retroflexus, the highest rise in grain yield, compared to non-fertilization was related to compost (184.152), manure (119.24%), biochar (55.76%) and nitrogen (43.99%) treatments respectively. At low competitive weed density, the greatest increase in the grain yield was observed in compost (132.33%), manure (104.43%), biochar (55.71%) and nitrogen (22%) treatments compared to no fertilizer. In the absence of Amaranthus retroflexus, the highest to the lowest level of yield was obtained from the treatments of nitrogen, manure, compost, biochar and no fertilizer, while no statistically significant difference was found between nitrogen treatment and manure.
Effects of COVID-19-related worry and rumination on mental health and wellbeing during the pandemic: Longitudinal analyses of adults in the UK COVID-19 Mental Health & Wellbeing study

Background: The lasting effects of the coronavirus disease 2019 (COVID-19) pandemic are likely to be significant, particularly in regard to mental health and wellbeing. The current study aimed to track worry and rumination (perseverative cognition) levels during the COVID-19 pandemic and to investigate whether periods with higher COVID-related worry and rumination were associated with more negative mental health outcomes in the UK population. Methods: Quota survey design and a sampling frame that permitted recruitment of a national sample was employed. Findings for waves 1 (31 March-9 April 2020), 2 (10 April-27 April 2020), 3 (28 April-11 May 2020), 4 (27 May-15 June 2020), 5 (17 July-7 August 2020) and 6 (1 October-4 November 2020) are reported here (N=1943 adults). At each wave COVID-related worry and rumination were assessed together with depression, anxiety and mental wellbeing.Results: Worry and rumination levels were highest at the beginning of the first UK lockdown and declined across the six waves but increased when the UK returned to lockdown. Worry levels were significantly higher than rumination levels throughout. COVID-related worry and rumination were significantly associated with higher symptoms of depression, anxiety and lower wellbeing. The adverse effects of COVID-related worry on depression and anxiety levels were most marked in individuals living with a pre-existing mental health condition. Conclusions: Psychological interventions should include components that specifically target COVID-related worry and rumination. Individuals with pre-existing mental health conditions should be prioritised as we continue to emerge from the current pandemic and in any future public health crises.
Pursuit of complete markets: the missing perspectives

India's financial sector reform path has been a measured, cautious and steady process, aiming to attain standards of international best practice, but fine-tuning the process keeping the context in view. Although much has been achieved, this paper focuses on the remaining gaps. But post-crisis the pursuit of complete markets is no longer the holy grail of regulation. In particular, underlying needs and systemic risk assessment should drive the regulatory framework for cash markets, not the elusive search for market completion and efficient derivatives markets.
Interrogating theoretical and empirical approaches to employability in different global regions

This special issue expands the scope of a panel presentation at the Society for Research into Higher Education Annual Conference 2019 and makes two identified contributions to the field. First, drawing from existing literature, this introductory paper proposes three categorisations of employability as: outcomes approach, process approach and conceptual approaches. This moves beyond normative conceptualisation of employability from mostly the outcomes approach. The applicability of the categorisation is further enumerated by the diversity of contributions in this special issue that highlights (a) the complexity in the field and (b) the interrelatedness of the categories. Second, the special issue puts together a rarely combined collection of global perspectives on conceptualisations of employability, and insights from research on little studied groups in Western and non‐Western contexts (the UK, Portugal, Australia, the Indo‐Pacific Region, Germany, Kenya and Kazakhstan). The papers, therefore, illustrate the need to widen our scope of understanding employability beyond current dominant perspectives. The broadening that is required in employability discourses is further needed in view of unprecedented disruption brought on higher education during the COVID‐19 pandemic. This suggests the need to rethink our conceptualisations of employability amidst uncertainty and potential disruption to the future of work.

Design, Synthesis and Antibacterial Activity Evaluation of 4,5-Diphenyl-1H-Imidazoles Derivatives

Due to the continuous emergence and rapid spread of drug-resistant strains of bacteria, there is an urgent need for the development of novel antimicrobials. Along this line, the synthesis and antibacterial activity of 4,5-diphenylimidazol-2-thiol derivatives 2a-g and 6a-e are reported. The structures of the synthesized compounds were confirmed by Nuclear Magnetic Resonance (NMR) and High Resolution Mass Spectrometry (HRMS). All compounds were screened in vitro for their antibacterial activity against Pseudomonas aeruginosa and Escherichia coli (Gram-negative bacteria) and also against Staphyloccocus aureus and Enterococcus faecalis (Gram-positive bacteria). The results showed most of the synthesized compounds have no antibacterial activity. However compound 6d was two-fold potent than ciprofloxacin against Staphylococcus aureus with Minimum Inhibitory Concentration (MIC) of 4 μg/mL and 6c showed moderate biological activity against Staphylococcus aureus (16 μg/mL) and Enterococcus faecalis (16 μg/mL).
An Emerging Trend of Slow Tourism: Perceptions of Hungarian Citizens

Besides slow food, slow city, slow fashion, education, and marketing - slow tourism is one of the several different slow movements. Several trends justify the importance and the reasons for the existence of slow tourism: the aging society, the growing power of women in making travel decisions. Slow tourism was born as a possibility for those, who would like to live their life in a different way even during their travels: giving respect to the environment and to the local people, too. In case of slow tourism local culture, traditions, gastronomy is in the center. Sustainability is also a priority, meanwhile, the well-being and interests of the inhabitants of the destination are also taken into account. Instead of mass tourism products authentic, not standardized experiences are in the supply. The research aimed to investigate the attitudes and perceptions of respondents towards different slow tourism elements. The study is based on quantitative data from an online survey conducted with 386 Hungarian respondents in the framework of omnibus research. To reveal the perceptions and attitude of the respondents towards slow elements multidimensional scaling model and principal component methods were applied. Based on the results it can be concluded, that the "local" elements of a journey are important for the respondents, meanwhile, the personalized services, the spirituality of the destination, and the sustainable approach do not matter. Only a small proportion of respondents avoids crowded destinations, so traveling to hidden places is not a favorite holiday option for the majority of Hungarians. However, the coronavirus epidemics can strengthen the demand for this tourism product, since expectedly there will be more tourists, who want to avoid crowded places during their holiday. Service providers can also benefit from the results of the research, and concentrate on the elements that proved to be important for Hungarian travelers.
Credibility in Online Health Communities: Effects of Moderator Credentials and Endorsement Cues

Online health communities (OHCs) are a common and highly frequented health resource. To create safer resources online, we must know how users think of credibility in these spaces. To understand how new visitors may use cues present within the OHC to establish source credibility, we conducted an online experiment (n = 373) manipulating cues for perceptions of two primary dimensions of credibility—trustworthiness and expertise—by manipulating the presence of endorsement cues (i.e., likes) and of moderators’ health credentials (i.e., medical professional) using a fake OHC. Participants were predominantly male (60.4%) and Caucasian (74.1%). Our findings showed that moderators with health credentials had an effect on both dimensions of source credibility in OHCs, however, likes did not. We also observed a correlation between the perceived social support within the community and both dimensions of source credibility, underscoring the value of supportive online health communities. Our findings can help developers ascertain areas of focus within their communities and users with how perceptions of credibility could help or hinder their own assessments of OHC credibility.
ON THE ΔVbumpHB PARAMETER IN GLOBULAR CLUSTERS

We present new empirical estimates of the ΔVbumpHB parameter for 15 Galactic globular clusters (GGCs) using accurate and homogeneous ground-based optical data. Together with similar evaluations available in the literature, we ended up with a sample of 62 GGCs covering a very broad range in metal content (−2.16 dex ⩽ [M/H] ⩽ −0.58 dex). Adopting the homogeneous metallicity scale provided either by Kraft & Ivans or by Carretta et al., we found that the observed ΔVbumpHB parameters are larger than predicted. In the metal-poor regime ([M/H] ≲ −1.7, −1.6 dex) 40% of GCs show discrepancies of 2σ (≈0.40 mag) or more. Evolutionary models that account either for α- and CNO-enhancement or for helium enhancement do not alleviate the discrepancy between theory and observations. The outcome is the same if we use the new solar heavy-element mixture. The comparison between α- and CNO-enhanced evolutionary models and observations in the Carretta et al. metallicity scale also indicates that observed ΔVbumpHB parameters, in the metal-rich regime ([M/H] ⩾ 0), might be systematically smaller than predicted.
Internal Audit Function and Audit Fees: Evidence from Nigeria

The purpose of this study is to analyse the relationship between audit fees and internal audit function in the Nigerian listed companies. This study observes 60 non-financial firms over four years (2012 to 2015) and uses random effect regression model to examine the hypothesis. The result of the study found internal audit to be significantly related with amount of audit fees paid by the listed firms. Specifically, this study found internal audit expertise and size of internal audit unit to have a positive and significant relationship with audit fees while no relationship was documented between internal audit certificate and the amount of audit fees. The study concludes that company with effective and adequate internal audit unit tend to pay higher audit fees to the external auditors.
A Statistical Formulation for Master Modulus Curves of a Vinyl Ester Polymer

ABSTRACT Master modulus curves are developed for a vinyl ester polymer with variability in its material properties. Tensile creep strains were obtained at three temperatures below the Tg through digital image correlation. A spectrum function was used to represent the viscoelastic strain response and modulus. A two-parameter Weibull distribution was used to characterize the probability distribution of the longitudinal modulus. The Weibull probability density functions of the viscoelastic modulus were obtained for each test configuration and found to be time and temperature dependent. Longitudinal modulus curves at constant probabilities were used to develop the master curves using the time–temperature superposition principle. GRAPHICAL ABSTRACT
