Abstract Two isostructural (in room temperature) complexes of Bi(III) with halogens and sulfur ligands have been investigated in terms of the solid-to-solid phase transitions indicated by temperature. Both chloride and bromide (X) complexes of the general formula (µ2-X)-(BiX2L2)2 exhibit some phase transitions between 100 and 333 K, which, apart from the numerous similarities, show significant differences, which have been noted and analyzed in detail in this paper by using different techniques, i.e., powder and single crystal diffraction or DSC. The obtained results have also been collated with those obtained for solid solutions of both complexes.

Rationale is the search for an answer to the question that concerns many today, whether it is possible to ensure the security of the individual and the state as a whole by means of language in a communicative space filled with threats of a different nature. The aim of the study is to prove that raising of speech culture level as an extremely relevant field of knowledge and a sphere of practical competences in the face of new challenges of modernity should become the subject of closer comprehension not only of specialists but also of the native speakers of the Russian language, since the contemporary speech is one of the components of national well-being. Materials and methods. The data used are works on the culture of speech, orthology, and communicativism, legislative acts, as well as various linguistic factual materials inherent in modern discourse. The analysis was carried out by means of descriptive, stylistic, statistical, and contextual methods; the study of the factual material was carried out by means of observation and questioning. Results. The results of the study showed that improving the speech culture of modern Russian speakers cannot an aim, and the approach to solving this problem is formalized and not aligned with the new reality. In the current conditions, when communicative activity becomes difficult to regulate, a special life-saving means is the speech culture of a person, often in the literal sense of the word, ensuring his or her physical survival. Results application. The results might be applied in the course “Russian Language and Speech Culture” as well as might be useful for the teachers who teach this cycle of disciplines in institutions of higher education.

In this paper we consider a fractional order Logistic model with Caputo-Fabrizio fractional derivative. By applying two-step Adams-Bashforth scheme, we obtain a system of difference equations. By using the Schur-Cohn criterion, stability conditions of the positive equilibrium point of the discrete system are obtained. It is observed that the discrete system shows much richer dynamic behaviors than its fractional-order form such as Neimark-Sacker bifurcation and chaos. The direction and stability of the Neimark-Sacker bifurcation are determined by using the normal form and center manifold theory. In addition, the effect of fractional order parameter on the dynamical behavior of the system is investigated. Finally, numerical simulations are used to demonstrate the accuracy of analytical results.

Bread wheat (Triticum aestivum L) is one of the three main staple crops worldwide contributing 20% calories in the human diet. Drought stress is the main factor limiting yields and threatening food security, with climate change resulting in more frequent and intense drought. Developing drought-tolerant wheat cultivars is a promising way forward. The use of holistic approaches that include high-throughput phenotyping and genetic markers in selection could help in accelerating genetic gains. Fifty advanced breeding lines were selected from the CIMMYT Turkey winter wheat breeding program and studied under irrigated and semiarid conditions in two years. High-throughput phenotyping was done for wheat crown root traits and canopy senescence dynamics using vegetation indices (green area using RGB images and Normalized Difference Vegetation Index using spectral reflectance). In addition, genotyping by KASP markers for adaptability genes was done. Overall, under semiarid conditions yield reduced by 3.09 t ha-1 (-46.8%) compared to irrigated conditions. Genotypes responded differently under drought stress and genotypes 39 (VORONA/HD24-12//GUN/7/VEE#8//…/8/ALTAY), 18 (BiII98) and 29 (NIKIFOR//KROSHKA) were the most drought tolerant. Root traits including shallow nodal root angle under irrigated conditions and root number per shoot under semiarid conditions were correlated with increased grain yield. RGB based vegetation index measuring canopy green area at anthesis was better correlated with GY than NDVI was with GY under drought. The markers for five established functional genes (PRR73.A1 -flowering time, TEF-7A -grain size and weight, TaCwi.4A - yield under drought, Dreb1- drought tolerance, and ISBW11.GY.QTL.CANDIDATE- grain yield) were associated with different drought-tolerance traits in this experiment. We conclude that-genotypes 39, 18 and 29 could be used for drought tolerance breeding. The trait combinations of canopy green area at anthesis, and root number per shoot along with key drought adaptability makers (TaCwi.4A and Dreb1) could be used in screening drought tolerance wheat breeding lines.

hotosynthetic response to light was measured on the leaves of two cultivars of Rosa hybrida L. (Escimo and Mercedes) in the greenhouse to obtain light-response curves and their parameters. The aim was to use a model to simulate leaf photosynthetic carbon gain with respect to environmental conditions. Leaf gas exchanges were measured at 11 light intensities from 0 to 1,400 µmol/m2s, at 800 ppm CO2, 25°C, and 65 ± 5% relative humidity. In order to describe the data corresponding to different measurement dates, the non-linear mixed-effects regression analysis was used. The model successfully described the photosynthetic responses. The analysis indicated significant differences in light saturated photosynthetic rates and in light compensation points. The cultivar with the lower light compensation points (Escimo) maintained a higher carbon gain despite its lower (but not-significant) quantum efficiency. The results suggested acclimation response, as carbon assimilation rates and stomatal conductance at each measurement date were higher for Escimo than Mercedes. Differences in photosynthesis rates were attributed to the adaptive capacity of the cultivars to light conditions at a specific day when the experiments were undertaken.

ABSTRACT Objectives: to examine the effects of urethroplasty surgery on sexual functions by taking into account age, location of stenosis, length of stenosis and surgical technique parameters. Materials and Methods: The prospective study was conducted between January 2015 and August 2017 with 60 cases. Patients were categorized according to age groups (19-65 / 65-75 years), surgery technique and stricture localization and length. Before the urethroplasty operation and postoperative 6th month follow-up, the international index of erectile function (IIEF) form (15 questions), was filled, the relevant domains of sexual function; erectile function (Q1,2,3,4,5,15), orgasmic function (Q9,10) and overall satisfaction (Q13,14) were assessed. Results: The mean age of the cases is 54 ± 13. However, preoperative IIEF, sexual satisfaction and orgasmic function averages of patients with a stenosis segment length of 1-3 cm was found to be significantly higher than that of patients with a stenosis segment length of 4-7 cm. Between stenosis segment length groups, there was no statistical difference in terms of preoperative and postoperative sexual functions. And also, there was no statistically significant change in patients’ preoperative and postoperative sexual function scores in terms of localization of stricture and surgery techniques. However, there were statistically significant change in the postoperative IIEF and sexual satisfaction averages according to preoperative averages. Conclusion: Our study suggests that urethroplasty surgery itself does not significantly affect erectile function, orgasmic function, and general sexual satisfaction regardless of the type of surgery, localization and length of stenosis. Besides, there was a significant decrease in erectile function in senior adults.

Background: Each year, millions face natural disasters, encountering mass fatalities and severe medical issues such as crush injuries and crush syndrome. Crush syndrome, marked by acute kidney injury (AKI) and hyperkalemia, correlates with mortality. This study focuses on presenting epidemiological data on kidney disease resulting from the February 6, 2023 earthquakes centered in Kahramanmaras., Methods: This retrospective analysis included patients diagnosed with crush syndrome after the 2023 Kahramanmaras earthquakes, treated in regional hospitals or referred elsewhere in Turkey. Patient data were documented using the web-based system developed by the Turkish Nephrology Association Renal Disaster Working Group., Results: Of the 1024 analyzed patients from 46 centers, 515 (50.3%) were women. The mean age was 41 ± 16 years, with a median duration of 12 h under rubble, and the median presentation time to the first health facility was 4 h after extrication from the rubble. Upon admission, 79.8% received intravenous fluid therapy, all potassium-free. Initial serum creatinine, K + , and creatinine kinase levels averaged 2.59 ± 2 mg/dl, 5.1 ± 1 mmol/L 38,305 ± 54,303 U/L, respectively. Intensive care unit (ICU) admissions were 53.6%, with mean hospital and ICU stays of 20 and 11 days, respectively. Compartment syndrome occurred in 40.8% of patients, with 75.8% undergoing fasciotomy. Acute kidney injury developed in 67.9% of patients, with 70.3% undergoing hemodialysis, totaling 3016 sessions on 488 patients. The overall in-hospital mortality rate was 9.8%., Conclusion: Earthquakes have a significant impact on kidney health. Although our study indicates some progress compared to previous earthquake responses, there remains a crucial need for drills emphasizing post-earthquake initial response, fluid-electrolyte balance management, and emergency dialysis protocols., Competing Interests: Declarations.

Purpose: In this study, we will investigate the possible side effects of psoriasis patients using long-term topical corticosteroids (TCS) such as adrenal insufficiency, Cushing's Syndrome (CS) and osteoporosis and determine how these side effects develop., Material and Methods: Forty-nine patients were included in the study. The patients were divided into two groups based on the potency of the topical steroid they took and the patients' ACTH, cortisol and bone densitometer values were evaluated., Results: There was no significant difference between the two groups regarding the development of surrenal insufficiency, CS and osteoporosis. One patient in group 1 and 4 patients in group 2 were evaluated as iatrogenic CS. ACTH stimulation tests of these patients in group 2 showed consistent results with adrenal insufficiency, while no adrenal insufficiency was detected in the patient in Group 1. Patients who used more than 50g of superpotent topical steroids per week compared to patients who used 50g of superpotent topical steroids per week. It was identified that patients who used more than 50g of superpotent topical steroids had significantly lower cortisol levels, with a negatively significant correlation between cortisol level and the amount of topical steroid use ( p  < .01).Osteoporosis was detected in 3 patients in group 1 and 8 patients in Group 2. Because of the low number of patients between two groups, statistical analysis could not be performed to determine the risk factors., Conclusions: Our study is the first study that we know of that investigated these three side effects. We have shown that the development of CS, adrenal insufficiency and osteoporosis in patients who use topical steroids for a long time depends on the weekly TCS dosage and the risk increases when it exceeds the threshold of 50 grams per week. therefore, our recommendation would be to avoid long-term use of superpotent steroids and to choose from the medium-potent group if it is to be used.

Energy-efficient wastewater treatment plants (WWTPs) utilize systems like high-rate activated sludge (A-stage) system to redirect organics from wastewater are redirected into energy-rich sludge (A-sludge). Anaerobic membrane bioreactors (AnMBRs) offer lower footprint and higher effluent quality compared to conventional digesters. In this study, the biological treatment and the filtration performances of AnMBRs for A-sludge digestion under mesophilic and thermophilic conditions were comparatively evaluated through lab-scale experiments, mass balancing and dynamic modeling. Under thermophilic conditions, a higher COD fraction of the influent sludge was converted into methane gas than under mesophilic conditions (65% versus 57%). The energy balance indicated that the surplus energy recovery under thermophilic conditions was less than the additional energy required for heating the AnMBR, resulting in a more than three-fold higher net energy recovery under mesophilic conditions. Therefore, operating an AnMBR for sludge digestion under mesophilic conditions has a higher potential to improve the energy balance in WWTPs., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Background/Objectives : The Naples prognostic score (NPS), reflecting inflammation and nutritional status, has prognostic value, especially in cancer. This study evaluated its ability to predict in-hospital mortality in acute ischemic stroke (AIS) patients undergoing endovascular treatment (EVT). Methods : We retrospectively studied 244 patients with AIS who were admitted between April 2020 and December 2023. Patients were included if they presented within 6 h of symptom onset with evidence of intracranial proximal arterial occlusion. The EVT was performed using aspiration catheters, stent retrievers, or both. The NPS was calculated based on the neutrophil-lymphocyte ratio, lymphocyte-monocyte ratio, and albumin and total cholesterol levels. Results : We found a significant association between higher NPS scores and in-hospital mortality. Patients with a high NPS (3 or 4) had a mortality rate of 41.6% compared to 21.0% in the low-NPS group (0, 1, or 2). The full model incorporating NPS showed superior predictive ability for in-hospital mortality compared with the baseline model (areas under the curve 0.881 vs. 0.808). A receiver-operating characteristic analysis at a cutoff of >2.5 for the NPS showed a sensitivity of 86.6% and specificity of 41.9%. This study demonstrated that incorporating the NPS into the predictive model improved the accuracy and calibration for predicting in-hospital mortality. A decision curve analysis showed the net benefit of using the full model incorporating NPS over the baseline model, emphasizing its potential clinical application in prognostication. Conclusions : NPS is a reliable predictor of in-hospital mortality in AIS patients undergoing EVT. Incorporating NPS into clinical practice could help to identify high-risk patients and improve outcomes through tailored interventions.

The Sub-Saharan African (SSA) region remains the world's largest recipient of remittances. Due to growing concerns over climate change issues, recent studies have examined how these financial flows have affected environmental quality. Sundry variables were controlled in such studies concerning the remittances-environment nexus, including institutional quality. Notwithstanding that remittance and institutional quality are imperative, their combined effect on environmental quality has been overlooked. The present study has inspected how remittances and institutional quality have jointly influenced environmental quality in 44 economies in the SSA region between 2000 and 2022. Using PMG-ARDL analysis, the findings revealed that remittances had a negative long-term impact on environmental quality. Conversely, the study found that institutional quality positively affected the per capita ecological footprints, as measured by the six indicators' average. Furthermore, the results indicated that improvements in institutional quality over time mitigated the adverse impact of remittances on the environment in the sampled SSA countries. Additionally, a threshold level of institutional quality effectively moderates remittances' detrimental effects on environmental quality were identified. Therefore, most regional countries must enhance their institutional quality to mitigate the negative environmental impact of remittances., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

It is important to examine the ocular hemodynamic changes after carotid artery stenting (CAS) and carotid endarterectomy (CEA) in patients with internal carotid artery stenosis (ICAS). We aimed to compare the differences in retinal and optic nerve head blood flow after 2 surgical methods. The ipsilateral eyes of 34 patients who had over 50% ICAS with no ocular findings and 30 healthy controls were included in the study. Foveal avascular zone vessel density in the superficial retinal capillary plexus, deep retinal capillary plexus (DCP), and radial peripapillary capillary plexus (RPCP) were measured with an optical coherence tomography angiography device. These measurements were repeated 1 month after CAS or CEA in patients with ICAS. The preoperative and postoperative values of the patients were compared both within themselves and with the control group. When patients with ICAS were compared with the control group, lower vessel density values were found in the DCP parafovea, RPCP whole image, and peripapillary regions both before and after the procedure. There was no significant difference in terms of other parameters. Furthermore, there was no significant difference in any parameter examined between the pre- and postprocedural values of the patients who underwent CAS and CEA. DCP and RPCP are mostly affected in patients with ICAS. We observed that after application of the CAS and CEA methods, the effects on ocular blood flow were similar., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Unlike previous studies that have examined the association between different economic development parameters and environmental sustainability, the present study utilised an index of productive capacity to offer an in-depth understanding of the ecological impact of improving a nation's productive resources. It also emphasised the importance of remittances in reducing environmental degradation in uncertain economic and political environments. This study applied the system GMM technique and an advanced panel quantile regression technique to 36 Sub-Saharan Africa (SSA) region countries from 2000 to 2022. The findings showed that improvements in productive capacity might exert pressure on environmental quality, uncertainty, and the inflow of remittances, which tended to have a positive effect, ultimately leading to better environmental outcomes. Furthermore, the study indicated that these variables' impacts differed depending on each country's prevailing ecological conditions. It is, therefore, vital that efforts to achieve sustainable development in the SSA region consider the combined impact of these factors on environmental quality., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Peritoneal dialysis (PD) remains understudied in disaster nephrology. This retrospective multicenter study explores the experiences of PD survivors following the February 6, 2023, Kahramanmaraş Earthquake., Methods: Adult PD patients from 11 affected cities were analyzed to assess challenges faced during and postearthquake, alongside clinical outcomes., Results: Among 101 participants (median age: 45 years, median PD duration: 24 months), 57 were female, with 79 on continuous ambulatory PD. Challenges included power outages and water shortages, with primary shelter in kin's houses (33%) and homes (28%). Twelve patients experienced PD program delays, and three lacked assistance postdisaster. Sixteen patients changed PD modalities, with seven experiencing postearthquake peritonitis. Clinical parameters remained stable, except for a slight decrease in hemoglobin levels., Conclusion: Despite challenges, PD survivors exhibited resilience, highlighting the importance of addressing peritonitis and unusual pathogens in disaster preparedness initiatives., (© 2024 International Society for Apheresis and Japanese Society for Apheresis.)

The study aimed to determine the CCl 4 -induced liver fibrosis model in pinealectomized rats and biochemically, immunohistochemically, and histopathologically investigate the therapeutic effect of melatonin on liver fibrosis. The surgical procedure for pinealectomy was performed at the beginning of the study, and the sham and pinealectomized rats were administered CCl 4 dissolved in corn oil (1:1) alone every other day to induce liver fibrosis or together with melatonin (10 mg/kg) therapy for 15 days. Melatonin is an essential therapeutic agent and offers an alternative therapeutic strategy in CCl 4 -induced liver fibrosis by suppressing inflammation, oxidative stress, and the TGF-β1 signaling pathway. Treatment with melatonin ameliorated CCl 4 -induced liver fibrosis by restoring hepatocellular damage and reducing plasma AST, ALT, and ALP values. Melatonin increases the activity of SOD and CAT, which are important enzymes for antioxidant defence, and raises GSH levels, which further enhances antioxidant function. Also, melatonin reduced hepatic inflammation (IL-6 and IL-1β) and oxidative stress indices. Moreover, histopathological changes and immunohistochemical expression of TGF-β1 were restored following melatonin supplementation in the CCl 4 -induced liver fibrosis model in pinealectomized rats. Our study shows that melatonin supplementation has a beneficial effect in protecting the liver fibrosis induced by CCl 4 in pinealectomized rats., (© 2024. The Author(s).)

Objective: Uremic pruritus is a distressing complication of chronic kidney disease (CKD), associated with mortality, and negatively impacts quality of life. The 5D-Itch Scale (5D-IS) is an easy-to-apply technique that evaluates 5 different dimensions of itching such as duration, severity, course, disability, and prevalence. We aimed to investigate the prevalence of itching in different CKD stages using the 5D-IS and to investigate the factors associated with itching in CKD patients., Materials and Methods: 5D-IS was used to evaluate itching in chronic hemodialysis (HD) and Stage 3-5 CKD patients. Total itching score and sub-scores consist of duration, severity, course, disability and distribution were obtained. Itching scores and prevalence according to CKD stages were investigated. Also the relationships between itching scores and some laboratory and clinical parameters such as iPTH, Ca, P, CRP levels were examined., Results: 158 CKD patients included in the study included (110 Stage 3-5 and 48 HD). The frequency of itching was higher in HD patients than in predialysis patients (62.5% vs 46.4%; p = 0.04). The total itching score increased along with CKD stages 3 to 5 (7.75 ± 3.39, 7.82 ± 4.11 and 9.08 ± 5.12 respectively; p = 0.14). The severity, duration and course scores of itching were similar between the groups, but the distribution scores increased as the CKD stage increased. The laboratory and clinical characteristics of patients with and without itching were not different. Even if a significant positive correlation was detected between the parathyroid hormone levels and both the total 5D-IS scores and all of the sub-scores, Ca and P values were not correlated with itching scores. In the multiple regression analysis, the only parameter that had an effect on the total 5D-IS Score was the parathyroid hormone level., Conclusion: In CKD, itching affects 40-70% of patients from the early stages. As the CKD stage increases, itching spreads throughout the body. The only parameter that seems to be associated with itching is the PTH level., (© 2024.

Aim: The aim of the study is to investigate the relationship between negative acute-phase reactants and positive acute-phase reactants with in-hospital mortality in patients diagnosed with acute ischemic stroke (AIS) in the emergency department (ED)., Methods and Materials: Patients aged 18 and older who presented to the ED of a tertiary hospital with AIS were included in the study. Demographic and clinical characteristics, laboratory parameters, acute-phase reactants, National Institutes of Health Stroke Scale (NIHSS), and outcome data of the included patients were recorded on a standard data form., Results: A total of 588 patients were included in the study. When the in-hospital mortality of patients was examined, the mortality rate was 17.7%. In the analysis for predicting mortality, it was determined that albumin had the highest predictive power between the area under the curve (AUC) and the determined predictive values (AUC: 0.759, 95% CI 0.707-0.810, p  < 0.001). The analyses of the study data revealed that albumin (<0.001) and TF ( p  = 0.049), which are negative acute-phase reactants, were independent predictors of mortality. According to our study data, in patients with AIS, for each unit decrease in albumin level at the time of ED admission, the risk of mortality increased by 0.868 times, and for each unit decrease in TF level, the risk of mortality increased by 0.593 times., Conclusion: According to the study data, albumin and TF levels, which are negative acute-phase reactants, are independent determinants of in-hospital mortality in patients with acute ischemic stroke in the emergency department.

The impact of climate change has malformed the world's ecosystem, thus making humans call for environmental protection. Climate change, the biggest trauma of the twenty-first century, has made humans switch towards natural consumption. In this regard, the growing phenomenon of industrialization has spurred consumers to invest more in ecological products. Consuming eco-friendly products has several benefits; however, countries are still unable to satisfy the consumer's concern for the environment. The current study presents literature on environmental concerns, psychological well-being, willingness to pay for pro-environmental products, pro-environmental self-identity, and pro-environmental consumer behavior, which are required to ensure the consumer's organic behavior. The research used a questionnaire-driven methodology to gather data from 379 participants. Data analysis was conducted using statistical software packages, specifically SPSS (Version: 4.1.0.0). The suitability of the measurement model was evaluated through structural equation modeling (SEM), which was performed utilizing the SmartPLS. According to the research findings, there is a positive relationship between variables in the study, and individuals with greater levels of psychological well-being are more likely to engage in behaviors that promote sustainable consumption. In order to foster more sustainable consumption patterns in society, policymakers, marketers, and educators may find these findings to be valuable insights. As a result of its empirical exploration of these relationships, the study contributes to the growing body of literature on environmental psychology and sustainable marketing, emphasizing the important role psychological factors play in promoting a greener environment., (© 2024.

Rapid economic growth and human activities have seriously damaged the environment and hindered the achievement of Sustainable Development Goals (SDGs). Hence, this study aims to explore the impact of economic complexity, uncertainty, and remittance on environmental degradation in 134 countries from 2000 to 2022. In addition, it examines whether uncertainty moderates the relationship between remittance and environmental degradation. Two proxies (ecological footprint and CO 2 ) were used to measure environmental degradation. The analysis was conducted using a cross-sectional dependency test, second-generation unit root test, and panel quantile regression. The results revealed that economic complexity significantly and positively impacted environmental degradation, while uncertainty and remittance significantly and negatively impacted environmental degradation. Furthermore, uncertainty weakened the negative relationship between remittance and environmental degradation. Accordingly, this paper discusses various recommendations and policy implications regarding economic complexity, uncertainty, remittance, and environmental degradation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Purpose: Many countries have implemented unprecedented health measures since the World Health Organisation declared the novel coronavirus disease 2019 (COVID-19) a global pandemic. These measures have resulted in delays in the diagnosis of differentiated thyroid cancer (DTC). However, there is limited data on the impact of restrictions imposed during the pandemic on DTC management. Thus, the aim of this study is to analyse the clinicopathological and follow-up data of DTC patients diagnosed before and during the COVID-19 outbreak., Methods: This retrospective study included 191 DTC patients that were diagnosed between December 2018 and June 2021. The patients were divided into two groups: patients diagnosed before (December 2018 to February 2020) and during (March 2020 to June 2021) the COVID-19 pandemic. The clinicopathological and follow-up data between the two groups were compared., Results: Similar preoperative cytology results were obtained from the two groups. No difference with regard to tumour size, lymphovascular invasion and extrathyroidal invasion was observed between the two groups. While the American Thyroid Association risk stratification was similar between the two groups, radioactive iodine (RAI) therapy was applied less during the COVID-19 period. Although RAI therapy was administered at a lower rate during the COVID-19 period, the recurrence rates among patients after two years of follow-up were similar to those during the pre-COVID-19 period., Conclusion: Although the COVID-19 pandemic restrictions during the pandemic period caused difficulties in the management of DTC patients, this did not negatively affect their prognosis. These findings can confirm the applicability of active surveillance in DTC patients and may help change the real-life treatment practices in selected low-risk DTC patients., (© 2024.

Worldwide economies are determined to achieve sustainable development. In this pursuit, the role of SMEs and ICT has emerged as an inevitable choice for sustainable development. The literature on the impact of SMEs and ICT on sustainable development, particularly in China's context, is scarce. Therefore, the analysis aims to investigate the impact of SMEs and ICT on sustainable development in China for the period of 1998-2020. We have applied the ARDL model for empirical analysis. The short and long-run estimates attached to SMEs are significant and positive, confirming that SMEs help to achieve sustainable development. Similarly, the estimates attached to ICT are positive and significant both in the short and long run, confirming the beneficial role of ICT in achieving sustainable development. The estimates attached to institutional quality and R&D control variables are positive and significant in the long run, but only R&D estimates are significant in the short run. In particular, digitalization and SMEs development provide a win-win situation for China to mitigate climate change in the long run and become more environmentally sustainable., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

The objective of this study is to develop a mechanistic model to predict the long-term dynamic performance of High-Rate Activated Sludge (HRAS) process, including the removal of carbon (COD), nitrogen (N), and phosphorus (P). The model was formulated with inspiration from Activated Sludge Models No. 1 and 3 (ASM1 and ASM3) to incorporate essential mechanisms, such as adsorption and storage substrate, specific to HRAS systems. A stepwise protocol was followed for calibration with dynamic data from a pilot-scale HRAS plant. Sensitivity analysis identified influential model parameters, including maximum specific growth rate (μ), growth yield (Y H ), storage yield (Y STO ), storage rate (k STO ), decay rate (b), and half saturation of the readily biodegradable substrate for growth (K S1 ). The calibrated model achieved prediction efficiencies above the normalized Mean Absolute Error (MAE) of 70 % for mixed liquor suspended solids (MLSS), total chemical oxygen demand (TCOD), soluble COD (SCOD), particulate COD (XCOD), total nitrogen (TN), ammonia nitrogen (SNH), total phosphorus (TP), soluble TP (STP), and particulate TP (XTP). Uncertainty analysis revealed that SCOD was underestimated. Based on the dynamic profiles of uncertainty bands and observed data, there is potential for improving the estimation of dynamic behavior in STP. The observed discrepancies may be attributed to variations in wastewater characteristics during the monitoring period, particularly concerning the phosphorus (P) fractions of the readily biodegradable substrate (S S ) and soluble inerts (S I ), which were not considered as dynamically changing parameters in the model., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

The world is currently facing urgent climate and environmental issues, such as global warming, ecosystem collapse, and energy shortages. In this context, this study selected data from 2000 to 2021 and employed the Method of Moment Quantile Regression (MMQR) to thoroughly investigate the impact of renewable energy consumption, economic complexity, and geopolitical risks on the ecological footprint of the Group of Twenty (G20) countries. The results indicate that in countries with lower quantiles, renewable energy consumption significantly reduces the ecological footprint, whereas its effect is not prominent in countries with higher quantiles. Economic complexity has a negative impact on the ecological footprint, and this impact becomes stronger as the quantile of the ecological footprint rises. Additionally, economic complexity moderates the effect of renewable energy on the ecological footprint. Geopolitical risks facilitate the growth of the ecological footprint. Likewise, robustness tests such as DOLS, FMOLS, and quantile regression confirm these estimates in the same framework. This study has conducted a profound analysis of global environmental issues, offering innovative perspectives and recommendations for achieving goals related to sustainable energy utilization, mitigating climate change, and improving the ecological environment. The findings of this research will guide policymakers in G20 countries to adopt more effective environmental protection measures, thereby contributing to the construction of a sustainable future., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Coal is crucial for economic progress but equally baneful to the environment. Thus, the coal consumption-environmental sustainability nexus attracted the attention of both policymakers and scholars. This study evaluates the coal consumption-environment nexus in developed and developing countries over the period 2000-2020. We used panel data econometric techniques and the Augmented Anderson-Hsiao (AAH) two-step GMM estimator to assess and compare the impact of coal consumption on CO 2 . The findings revealed that the consumption of coal aggravates environmental pollution and hinders environmental sustainability. Thus, this study confirms the environment-destroying effect of coal consumption. However, the findings reveal that the negative consequence of coal consumption on the environment is more for the sample of developed countries than that of developing countries. This suggests that coal use harms the environment developed economies than the developing countries. Specifically, we found that the carbon emissions emanating from a one percent (1%) increase in coal consumption of the developed countries is about six-fold more than that of the developing countries. Therefore, this study suggests a gradual phase-out, rather than sudden phase-out, of coal consumption with greater emphasis on developed countries. The implementation of the coal phase-out policy and the removal of fossil fuel subsidies should start with the developed countries or be made more stringent in such countries than the developing economies. The developed countries should relinquish a greater proportion of their coal consumption than the developing countries., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.
