Photodegradation of Rhodamine-B using Gallium Hybrids as an Efficient Photocatalyst

Rhodamine B is a cationic xanthene dye widely used in the printing, textile, photography, and pharmaceutical industries. It is also well-recognized as water fluorescent and dyes laser material because of its good stability. It is toxic to human beings irritating the skin, and eyes. The present study is designed to study the photodegradation of Rhodamine B using gallium oxide and gallium hybrids as photocatalyst. Precipitation coupled with the sonochemical method is adopted for the synthesis of gallium oxide while the post grafting method is adopted for the synthesis of gallium hybrids with the indole and its derivatives. FTIR spectra showed the characteristic absorption bands of gallium oxide and gallium hybrids at 400-700 cm-1 and 1400-1600 cm-1. SEM and XRD showed the micro-sized rectangular rod-shaped gallium oxide with rhombohedral geometry. The BET isotherm revealed the adsorption type-IV and hysteresis loop (H3) proposing multilayer and mesoporous structures. XPS confirmed the presence of gallium, oxygen, nitrogen, and carbon. The gallium oxide and gallium hybrids showed 47-72% optimum degradation of Rhodamine B under two hours of illumination at pH 7 and 0.03mg/L. The degradation rate followed a Langmuir-Hinshelwood model with R2 >0.9.
Factors Influencing Satisfaction with Service Delivery Among National Health Insurance Scheme Enrollees in Ibadan, Southwest Nigeria

Perceived quality of care is a determinant of uptake of health services. This study aimed to assess the determinants of quality of care of enrollees in the National Health Insurance Scheme (NHIS) in Nigeria. The outcome was satisfaction with health care services, which was used as a proxy for quality. Findings will assist in the intervention to enhance enrollment in the scheme and for universal health coverage attainment. This was a descriptive cross-sectional study conducted among enrollees in selected NHIS facilities in Ibadan, Nigeria. Data on satisfaction with health care were collected among selected 432 enrollees with the aid of an adapted semi-structured WHO-USAID interviewer-administered questionnaire. Data were analyzed using chi-square and multiple logistic regression models (α = 0.05). Among predictors of satisfaction with health services were younger age (OR = 1.85, 95% CI = 1.05–3.25, p = .024), working in the private sector (OR = 1.84, 95% CI = 1.03–3.28, p = .022), and seeking information about quality of services prior enrollment (OR = 1.63, 95% CI = 1.04−2.53, p = .013). Targeted intervention based on the findings of this study should be implemented to improve satisfaction with the services offered.

Protective effect of carvacrol against hepato-renal toxicity induced by azathioprine in rats

Background and aims: Azathioprine (AZA) is an immunosuppressant medication that has toxicity to kidneys and liver. This study aimed to investigate the protective activity of carvacrol (CAR) against hepatorenal toxic activity of AZA in male Wistar rats. Methods: All study rats were divided into five groups: control (saline, ip); azathioprine-only (AZA 50 mg/kg, ip), Sily+AZA (Silymarin 50 mg/kg, gavage), CAR+AZA (CAR 10 mg/kg, gavage), and CAR+AZA (CAR 20 mg/kg, gavage) groups. Silymarin was used as the standard hepatoprotective drug. The drugs were administered once daily for 21 days in III-V groups, and a single dose of AZA was injected on the seventh day of the experiment. Results: AZA-intoxicated rats exhibited an elevation in aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase (ALP) activity in serum, as well as an increase in extent of lipid peroxidation. Activities of enzymatic antioxidants (superoxide dismutase – SOD, catalase - CAT) in the serum, liver, and kidney were decreased as for the AZA group (P<0.05). Co-treatment of CAR (both doses of 10 and 20 mg/kg) lowered the serum transaminases and ALP level, the elevation of endogenous enzymes levels, and the malondialdehyde (MDA) in serum and both tissues (P<0.05). This protective effect was greater in CAR 10 compared to 20 mg/kg doses, which was comparable to silymarin. Conclusion: This study demonstrated that the renal and nephrotoxic activities of AZA could be attributed to the generated increased oxidative stress, as well as to the CAR with antioxidant effect similar to that in silymarin, which protected these tissues against AZA-induced nephrotoxicity hepatotoxicity.
Our Gains, Pains and Hopes: Community Partners’ Perspectives of Service-Learning in an Undergraduate Business Education

In assessing the impact of service-learning, most studies focus on its effects on students’ learning than community partners and the communities served; leaving largely unanswered, the question of whether service-learning in business education still contributes value to community organizations and the wider society. This study investigates the impact of service-learning on communities through the perspectives of community partners from nonprofit and for-profit organizations in Canadian urban communities. Using semi-structured interviews and qualitative analysis, the authors collected and analyzed data from 30 participants to confirm their perspectives of service-learning in an undergraduate business education. The study found that service-learning offered practical benefits to communities and presented challenges that impacted partners’ experiences of service-learning. The penultimate sections of the paper provide recommendations for the improvement of the pedagogical practices of service-learning and advancement of community organizations. Key recommendations to maximize benefits for community partners include more faculty-community partners’ collaboration and creating networking opportunities for community partners.
Public understanding of climate change and support for mitigation

In this study, a large, representative sample of the Irish population undertook a multiple-choice quiz about climate change. The 10-minute quiz was designed to engage participants and to measure their understanding, not of facts and figures, but of the scientific relationships behind climate change – of what causes what, and how. The study was conducted in mid-October 2021. As well as revealing how well the population understands climate change, the central focus of the study was the relationship between understanding and willingness to act. To investigate this, the study contained an experiment that tested whether exposing people to the answers to the quiz questions altered their attitudes to climate policy and individual behaviour. Half the sample was randomly assigned to see the answers to the quiz questions, while the other half was not.We then measured support for climate mitigation policy (in particular, a carbon tax) and judgements of individual behaviour. In this way, we conducted an experimental test of whether engaging with accurate scientific information about climate change has an impact on willingness to tackle it.
Relationships Among Normative Beliefs About Aggression, Moral Disengagement, Self-Control and Bullying in Adolescents: A Moderated Mediation Model

Purpose Adolescent bullying has varying degrees of negative impact on both bullies and victims. Bullying in adolescents is complex, and the influence of individual factors and social factors should not be underestimated. Normative beliefs about aggression play an important role in adolescents’ bullying. However, the mediating and moderating mechanisms underlying this association remain largely unknown. The current study investigated the mediating role of moral disengagement between normative beliefs about aggression and bullying, as well as the moderating role of self-control in this relationship from the perspective of individual cognition. Methods A sample of 491 Chinese adolescents (female = 38.9%; mean age = 13.05 years) were study participants. They completed questionnaires about normative beliefs about aggression, bullying, moral disengagement and self-control. SPSS21.0 statistical software was used to collate the obtained data, analyze descriptive statistics, and carry out reliability analysis and correlation analysis. Results Moral disengagement mediated the relationship between normative beliefs about aggression and bullying (ab=0.13, 95% CI=[0.07, 0.21]). The association between normative beliefs about aggression and moral disengagement was moderated by self-control (β=−0.08, t=−2.25, p<0.05). The association between moral disengagement and bullying was moderated by self-control (β=−0.09, t=−2.42, p<0.05). Conclusion Results revealed that moral disengagement mediates the link between normative beliefs about aggression and bullying. Self-control moderated the relationship between normative beliefs about aggression and moral disengagement, and between moral disengagement and bullying.
The effect of psychological capital training on psychological burden and emotional self-regulation styles of mothers having children with cerebral palsy

Background and aims: This study aimed to investigate the effect of psychological capital training on psychological burden and emotional self-regulation styles of mothers having children with cerebral palsy. Methods: This quasi-experimental study was performed in 2019 on mothers of children with cerebral palsy who had files in rehabilitation centers under the supervision of Shahrekord Welfare (n=270). Samples were selected through convenience sampling method such that 30 people were selected from among eligible people and volunteers to cooperate, and then they were randomly divided into experimental and control groups. As for the intervention group, the psychological capital training program was implemented once a week for 10 sessions; but the control group was not given any intervention. Data were collected using the Psychological Burden Questionnaire designed by Zarit et al and the Emotional Self-Regulatory Questionnaire developed by Hoffman and Kashdan in three measurement steps. The collected data were analyzed by multivariate and repeated measure analysis of variance using SPSS-18 software. Results: The results showed that the mean scores of burden, secrecy, adaptability, and tolerance were significantly different in the post-test compared to the pre-test (P<0.05), as well as in the follow-up stage compared to the pre-test (P<0.001). Furthermore, the mean scores of post-test and follow-up for the experimental group increased in comparison with those for the control group in three styles of emotional regulation, and psychological burden decreased (P<0.001). Conclusion: The educational intervention of psychological capital could be adopted to increase using adaptive styles of emotional self-regulation, and to reduce psychological burden of mothers having children with cerebral palsy.
Update of the recommendations of the Sociedade Portuguesa de Cuidados Intensivos and the Infection and Sepsis Group for the approach to COVID-19 in Intensive Care Medicine

Introduction: The Sociedade Portuguesa de Cuidados Intensivos and the Infection and Sepsis Group have previously issued health service and management recommendations for critically ill patients with COVID-19. Due to the evolution of knowledge, the panel of experts was again convened to review the current evidence and issue updated recommendations. Methods: A national panel of experts who declared that they had no conflicts of interest regarding the development of the recommendations was assembled. Operational questions were developed based on the PICO methodology, and a rapid systematic review was conducted by consulting different bibliographic sources. The panel determined the direction and strength of the recommendations using two Delphi rounds, conducted in accordance with the principles of the GRADE system. A strong recommendation received the wording “is recommended”, and a weak recommendation was written as “is suggested. ” Results: A total of 48 recommendations and 30 suggestions were issued, covering the following topics: diagnosis of SARS-CoV-2 infection, coinfection and superinfection; criteria for admission, cure and suspension of isolation; organization of services; personal protective equipment; and respiratory support and other specific therapies (antivirals, immunomodulators and anticoagulation). Conclusion: These recommendations, specifically oriented to the Portuguese reality but that may also apply to Portuguese-speaking African countries and East Timor, aim to support health professionals in the management of critically ill patients with COVID-19. They will be continuously reviewed to reflect the progress of our understanding and the treatment of this pathology.
Two-port network model of wind turbine generator for three- phase unbalanced distribution system load flow analysis

Received May 19, 2021 Revised Oct 12, 2021 Accepted Jan 6, 2022 An unbalanced electric power system can occur due to unequal lines and/or loads in each phase of the system. For a system with a high level of unbalance, the assumption that the system is balanced becomes incorrect. For a case like this, the system must be analyzed using three-phase approaches because single-phase analysis techniques can no longer be used to obtain accurate results. Therefore, the development of three-phase models of all components of the electric power system, including the wind turbine generating system (WTGS), is very important so that the system can properly be analyzed and its performance can correctly be evaluated. This paper proposes a method to incorporate WTGS in a three-phase load flow analysis of an unbalanced distribution system. The proposed method is based on the previously published single-phase two-port network model. In this paper, the single-phase two-port network model is modified and extended so that it can be applied to unbalanced systems. The model is then included in the three-phase distribution system load flow (DSLF) analysis. The proposed method is validated using 12-node and 19-node distribution systems.
Economic uncertainty and structural reforms: Evidence from stock market volatility

Does economic uncertainty promote the implementation of structural reforms? We answer this question using one of the most exhaustive cross‐country panel data sets on reforms in six major areas and measuring economic uncertainty with stock market volatility. To identify causality, we exploit exogenous differential variation in countries' exposure to foreign volatility shocks due to predetermined and time‐invariant bilateral characteristics. Across all specifications, we find that stock market volatility has a positive and significant effect on the adoption of reforms. This result is robust to the inclusion of a large number of controls, such as political variables, economic variables, crisis indicators, and a host of country, reform and time fixed effects, as well as across various approaches for accommodating heterogeneous trends and contemporaneous shocks. Overall, this evidence suggests that times of market turmoil, which are characterized by a high degree of uncertainty, may facilitate the implementation of reforms that would otherwise not pass.
Dietary protein levels affected on the growth and body composition of tilapia (Oreochromis niloticus)

The experiment was carried out for 40 days in order to determine the effect of dietary protein levels on growth performance and body composition of tilapia (Oreochromis niloticus). Four isolipidic test diets, containing protein concentrations of 28, 32, 36 and 40%, each one with three replications, were used. Fifty fish with the average body weight of 5.0±0.5 g were reared in a 120 L aquarium. The specimens were fed three times daily. The results showed that the best O. niloticus growth performance was gained on the diet with the protein level of 40.06% (diet 4), with the weight gain (WG) and specific growth rate (SGR) values of 388.05±3.50% and 3.90±0.21% day, respectively. The WG and SGR values corresponding to the consumed diets containing protein at concentrations of 40.06% (diet 4) and 36.05% (diet 3) were not significantly different (p>0.05). Significant differences were shown for the body composition, including crude protein and amino acids profiles, as the effects of different dietary protein levels. The WG and SGR polynomial regression analysis showed that dietary protein requirements for the O. niloticus were 37.85 and 37.43%, while the dietary lipid level was 10.05%.
KOREAN JOURNAL OF ENGLISH LANGUAGE AND LINGUISTICS

The current study aims to explore to what extent L2 English student writers make their authorial presence explicit or implicit, using personal and impersonal authorial references in Applied Linguistics single-author research articles (RAs) throughout the whole RA or across article sections, compared to L1 English expert writers. The study constructed an L2 English corpus of 33 RAs written by Korean postgraduates and an L1 English corpus of 25 RAs written by L1 English scholars. It analyzed the frequency of four types of personal or impersonal authorial references in the two corpora: first-person singular and plural pronouns, their-person NPs and inanimate NPs. The results of the study revealed predominant use of inanimate NPs, abstract rhetors, in the two corpora; yet, author group variations were also noted from underuse of first-person singular and plural pronouns, overuse of third-person NPs, and less section-specific use of authorial references in the L2 English student writer corpus; and from preferred choice of specific impersonal self-reference expressions between the corpora. The findings from the study suggest not only the influence of impersonal written discourse style but also that of L2 English student writers’ native language, culture and literacy practice, and their status in the academic community and publication context, on their authorial references.
Characterizing binaural sensitivity to dynamic interaural level differences

Introduction The binaural system is usually described as being sluggish and there are many reports in the literature of time constants of binaural temporal windows, ranging from about 10 ms to 250 ms, depending on the experimental method. A recent physiological study [1] reported some neurons that respond to fluctuations in interaural correlation and encoded rates to at least an order of magnitude higher than the detectable rates reported in psychoacoustic studies using similar stimuli. In the current study, two psychoacoustic experiments were performed in order to determine if the binaural system is able to make use of the available temporal information or if a simple lowpass filter is sufficient to describe the performance of human listeners in binaural detection tasks with dynamic interaural cues.

Motor unit buckling in variable recruitment fluidic artificial muscle bundles: implications and mitigations

Fluidic artificial muscles (FAMs) are a popular actuation choice due to their compliant nature and high force-to-weight ratio. Variable recruitment is a bio-inspired actuation strategy in which multiple FAMs are combined into motor units that can be pressurized sequentially according to load demand. In a traditional ‘fixed-end’ variable recruitment FAM bundle, inactive units and activated units that are past free strain will compress and buckle outward, resulting in resistive forces that reduce overall bundle force output, increase spatial envelope, and reduce operational life. This paper investigates the use of inextensible tendons as a mitigation strategy for preventing resistive forces and outward buckling of inactive and submaximally activated motor units in a variable recruitment FAM bundle. A traditional analytical fixed-end variable recruitment FAM bundle model is modified to account for tendons, and the force–strain spaces of the two configurations are compared while keeping the overall bundle length constant. Actuation efficiency for the two configurations is compared for two different cases: one case in which the radii of all FAMs within the bundle are equivalent, and one case in which the bundles are sized to consume the same amount of working fluid volume at maximum contraction. Efficiency benefits can be found for either configuration for different locations within their shared force–strain space, so depending on the loading requirements, one configuration may be more efficient than the other. Additionally, a study is performed to quantify the increase in spatial envelope caused by the outward buckling of inactive or low-pressure motor units. It was found that at full activation of recruitment states 1, 2, and 3, the tendoned configuration has a significantly higher volumetric energy density than the fixed-end configuration, indicating that the tendoned configuration has more actuation potential for a given spatial envelope. Overall, the results show that using a resistive force mitigation strategy such as tendons can completely eliminate resistive forces, increase volumetric energy density, and increase system efficiency for certain loading cases. Thus, there is a compelling case to be made for the use of tendoned FAMs in variable recruitment bundles.
