AbstractThree small molecules consisting of thieno‐fused naphthalimide units connected via aromatic linkers were synthesized to study the effect of fused thiophene rings on the properties of naphthalimide‐based molecules. A protocol for the synthesis of thienonaphthalimide‐based molecules without prior preparation and use of thienonaphthalimide precursors and organoelement compounds (organolithium, organotin, or organoboron compounds) was developed. The protocol is based on double thienannulation of bis‐alkyne substrates with sodium sulfide. The thin‐film morphology, photophysical and electrochemical properties of the obtained small molecules were studied. Single‐layer non‐doped organic light‐emitting diodes based on fluorene‐bridged thienonaphthalimide dimer showed yellow emission with luminance of 2200 cd/m2, and current efficiency of 0.35 cd/A. Combination of transient electroluminescence and photo‐CELIV methods allowed to estimate electron and hole mobility in the synthesized compounds; both are in order of 10−6 cm2V−1 s−1.

AbstractA novel strategy of visible‐light photoredox catalysis ipso‐annulation of activated alkynes with polychloroalkanes for the synthesis of 3‐polychloroalkyl spiro[4,5]trienones, which used 4‐methoxybenzenediazonium tetrafluoroborate salt as a hydrogen atom transfer reagent, is described. This polychloroalkylation/ spirocyclization of alkynes offers a widely range of 3‐polychloroalkyl‐spiro[4,5]trienone derivatives in high yields with a broad substrate scope via selective C(sp3)‐H homolytic cleavage. The results of controlled experiments showed that this method involves a radical process. The polyhaloalkyl radical species generated from intermolecular hydrogen atom transfer (HAT) between aryl radical and polychloroalkanes.

Published: December 2023

AbstractThis work describes a carbon composite modified electrode (CCME) easily prepared using a simple mixture of a commercial cation exchange resin (Amberlite IR 120H) as modifier, graphite powder and paraffin, which was successfully used for spontaneous preconcentration and voltametric determination of carbendazim (CBZ) in juice samples. Parameters such as amount of resin used in the composition of the electrode, pH and preconcentration time as well as instrumental parameters of differential pulse voltammetry (DPV) were studied. Under optimized conditions, the proposed sensor shows to be able to preconcentrate CBZ at an open circuit potential (OCP) condition and presented the highest analytical response in comparison to the unmodified electrode. An analytical curve was obtained for the CBZ determination employing the proposed CCME and showed a linear dynamic range (LDR) between 80.0 nmol L−1 to 2.0 μmol L−1, with a LOD of 19 nmol L−1 and LOQ of 65 nmol L−1. The effect of concomitants on the voltametric response was evaluated by addition and recovery study and a good selectivity was found. The proposed sensor was successfully applied for the determination of CBZ in spiked mango juice samples without any pretreatment.

Published: December 2023

AbstractThis work addresses the ongoing challenge of optimizing sand control screens, attributed to a limited understanding of screen blocking. A novel one‐way computational fluid dynamics and discrete element method (CFD–DEM) coupling technique is presented to analyze the structural parameters of unconsolidated prepacked gravel screens (PPGS). CFD–DEM involves systematically investigating the width of the punched slot on the outer protective screen, the size of the gravel, and the efficiency of gravel packing to improve the antiblocking capability of unconsolidated PPGS. Results from numerical simulations reveal that under conditions of effective sand control, the amount of sand entering the gravel layer to the bridge (referred to as the sand pass rate) is positively correlated with the antilocking ability (referred to as oil productivity index) for unconsolidated PPGS. The efficiency of gravel packing has the most substantial effect on the antilocking performance of unconsolidated PPGS. The data suggest that appropriately reducing the efficiency of gravel packing can enhance the antilocking capability of unconsolidated PPGS. To design an unconsolidated PPGS with enhanced antilocking capability, the efficiency of gravel packing be determined first. Then, the gravel size is designed based on this efficiency, and the width relative to the gravel size is decided. This contemporary design principle diverges considerably from previous design principles for gravel‐packed sand control screens. Supporting validation experiments agree with simulation outcomes, suggesting the established one‐way CFD–DEM coupling method in this paper is suitable for analyzing the plugging mechanism of unconsolidated PPGS. Thus, the CFD–DEM coupling method improves the design of such screens for improved antiblocking performance.

Published: December 2023

AbstractWith the advancement of coal resources mining to the deep part, the control of the surrounding rock of the roadway has become one of the main problems in the field of mining. At the present stage, the bolt support technology of the roadway in China still faces problems such as unclear support mechanism and poor support effect. Based on the mechanism of bolt support, through theoretical analysis and experimental research, this study proposes the differentiated support technology for roadways based on the mechanical response of the plastic zone and applies this method in the Gada Coal Mine. The results of the study showed that the plastic zones with different shapes have different mechanical responses. compared with other plastic zone shapes, the control method of the roadway with a butterfly‐shaped plastic zone is more complex. Consequently, the support design of a bolt should not only consider the scope of the plastic zone of support construction but also grasp the development law of the plastic zone. Effective support measures should be taken as early as possible for roadways with butterfly‐shaped plastic zones to prevent aggressive development of the butterfly‐shaped plastic zone. Field tests show that this support method realizes the ideal supporting effect in practical applications.

Published: December 2023

AbstractResponse coordination design becomes an inevitable trend based on the multidisciplinary optimization design (MOD) in the development of the design for complex mechanical structures. Aiming at the problem of unclear mechanism of response coordination for main loaded structures, a response coordination design technology characterized by a response coordination evaluation system is proposed based on an analytic hierarchy process. In addition, a nondominated sorting elephant herding optimization (NSEHO) algorithm is proposed by introducing the Pareto optimization theory into elephant herding optimization and combining fixed‐sized candidate set adaptive random testing algorithm to overcome inherent limitations of the traditional algorithm in response coordination design. Taking the main bearing assembly structure as an example, the response coordination design is conducted based on the proposed technology and NSEHO algorithm. The response coordination design scheme of the main bearing assembly structure is experimentally verified. The results show that the Pareto frontier of NSEHO is smoother and is closer to the real Pareto frontier compared to NSGA‐II in condition of small population size and restricted iteration generations, revealing the advancement of the solving ability of NSEHO. The coordination coefficients of strength, stiffness, contact strength, and mass of the main bearing assembly structure are increased by 13.91%, 14.96%, 2.63%, and 0.07%, respectively, and the overall coordination coefficient are increased by 11.10%. The indicators of strength, stiffness, and contact strength of the response coordination scheme are better than those of the original scheme by experimental verification, demonstrating the effectiveness of the response coordination design technology. The proposed technology reveals the response coordination mechanism of the main loaded structures of internal combustion engines and provides an important guiding significance to MOD for complex mechanical structures.

Published: December 2023

AbstractThe NOVA food classification system is a simple tool that can be used to assess the consumption levels of different categories of foods based on their level of processing. The degree to which food is processed has a significant impact on health outcomes. In Ghana, no study exists on the consumption of the different NOVA food groups among tertiary students and how it relates to their metabolic outcomes. This study assessed the frequency of food intake according to the NOVA classification and how they relate to body mass index, waist circumference, and blood pressure. The barriers to the consumption of healthy foods among students were also assessed. This was a cross‐sectional study conducted among 352 students of the Takoradi Technical University. Questionnaire was used to obtain sociodemographic information as well as data on perceived barriers to healthy food consumption. Food frequency questionnaire was used to obtain data on dietary intake. The weight, height, waist circumference, waist‐to‐hip ratio, and blood pressure of all participants were measured. Chi‐square was used to compare categorical variables between males and females and to determine the association between the frequency of food intake according to the NOVA classification and metabolic indicators. The prevalence of overweight and obesity was 23.8%. More than half (51.1%) of the students had elevated blood pressure. The majority of study participants (54.2%) had a high frequency of consumption of both unprocessed and ultra‐processed foods. Male students who frequently consumed ultra‐processed foods (1–6 times/day) had significantly high blood pressure. High consumption of both ultra‐processed and unprocessed foods was also associated with elevated blood pressure among male students. Limited time to prepare healthy meals and the high cost of unprocessed foods were among barriers to which most students strongly agreed to. Establishment of canteens that provide affordable healthy foods, teaching students time management, and nutrition education can mitigate barriers to healthy food consumption.
The advantages of general anesthesia subthalamic deep brain stimulation for Parkinson's disease in the enhanced recovery after surgery: A randomized clinical trial
Authors: Guo Cunbao , Gao Taihong 
Published: December 2023

AbstractBackground and AimsWith advancements in imaging and microelectrode recording techniques, general anesthesia (GA) has emerged as an alternative option for Parkinson's disease (PD) patients undergoing subthalamic nucleus deep brain stimulation (STN‐DBS). In this study, we compared the advantages and disadvantages of using GA and local anesthesia for STN‐DBS in enhanced recovery after surgery (ERAS).MethodsSurgical outcomes of STN‐DBS were evaluated using the unified PD rating scales (UPDRS). CT and magnetic resonance imaging scans are used to evaluate intracranial conditions. State‐trait anxiety inventory and hospital anxiety and depression scale are used to evaluate patients' perioperative psychology.ResultsAnesthesia method does not significantly impact the accuracy of microelectrode placement or the improvement of postoperative symptoms. However, the local anesthesia group had a higher incidence of intracranial air, as well as higher rates of postoperative complications such as headache, dizziness, vomiting, and delirium. GA effectively alleviated preoperative anxiety and resulted in lower levels of perioperative anxiety and psychological stress compared to local anesthesia. Additionally, the GA group had shorter surgery duration, earlier ambulation, and a shorter average hospital stay.ConclusionDBS under GA is safe and effective. Due to shorter surgical duration, reduced occurrence of perioperative complications, effective reduction of preoperative anxiety, and faster postoperative recovery, DBS under GA is better aligned with the concept of ERAS.
Physical modeling and numerical investigation of fluid flow and solidification behavior in a slab caster mold using hexa‐furcated nozzle
Authors: Sharma Kapil Kumar , Kumar Rajneesh , Jha Pradeep Kumar 
Published: December 2023

AbstractSlag entrapment from metal–slag interface during continuous casting operations has been a major area of concern for steelmakers globally. The presence of inactive regions in the upper region of the mold poses another challenge. Proper flow behavior of the molten metal coming out of the nozzle in the mold is required to overcome these challenges. Nozzle design greatly affects the flow pattern of the molten steel inside the mold. The present investigation is an attempt to study the flow and solidification behavior in a slab caster mold with the use of a novel‐designed hexa‐furcated nozzle using numerical investigation results. The casting speed and submerged entry nozzle (SEN) depth are varied to study the effect of these parameters on minimizing the inactive zones in the mold and the steel/slag interface fluctuations. The results show that the interface fluctuation increases at higher casting speed and lower SEN depth. The residence time distribution (RTD) analysis was also performed for different cases to investigate the flow behavior. The validation of the fluid flow and RTD curve inside the computational domain is carried out with the use of physical modeling.
Victimization and cybervictimization: The role of school factors
Authors: Menabò Laura , Skrzypiec Grace , Slee Phillip , Guarini Annalisa 
Published: December 2023

AbstractIntroductionVictimization and cybervictimization can negatively affect the subjective experience of well‐being. This effect can be mediated by school factors, even if a deep understanding of these factors still needs to be determined. The present study examined how peer network, teacher support, and school connectedness mediated the relationship between victimization, cybervictimization, and well‐being. We developed two mediation models, considering victimization (Model 1) and cybervictimization (Model 2) as predictors, well‐being as the outcome, peer network, teacher support, and school connectedness as parallel mediators, and gender as a covariate variable.MethodsThe sample comprised 563 Italian students (Mage = 11.5; 45% females). Students filled out a purpose‐built questionnaire investigating victimization and cybervictimization, peer network, teacher support, school connectedness, and well‐being. Two multiple mediation models were run using Process.ResultsThe two models showed similar patterns [Model 1: F(8, 169) = 34.35, p ≤ .001, R2 = .34; Model 2: F(8, 169) = 40.13, p ≤ .001, R2 = .34]. Indeed, victimization (Model 1) and cybervictimization (Model 2) had negative significant effects on peer network, teacher support, and school connectedness. However, their direct effects on well‐being were not significant, as peer network and school connectedness emerged as complete mediators between victimization (Model 1) and cybervictimization (Model 2) and well‐being. Males displayed higher levels of well‐being compared to females.ConclusionsPeer network and school connectedness play a crucial role in mediating the impact of victimization and cybervictimization on well‐being. Educators and policymakers should prioritize fostering supportive peer network and strengthening school connectedness to create an environment that mitigates the negative effects of victimization and cybervictimization, enhancing overall student well‐being.

Published: December 2023

AbstractWe examined associations between a validated, multidimensional measure of social determinants of health and population‐based hospitalization rates among children <18 years across 18 states from the 2017 Healthcare Cost and Utilization Project State Inpatient Databases and the US Census. The exposure was ZIP code‐level Child Opportunity Index (COI), a composite measure of neighborhood resources and conditions that matter for children's health. The cohort included 614,823 hospitalizations among a population of 29,244,065 children (21.02 hospitalizations per 1000). Adjusted hospitalization rates decreased significantly and in a stepwise fashion as COI increased (p < .001 for each), from 26.56 per 1000 (95% confidence interval [CI] 26.41–26.71) in very low COI areas to 14.76 per 1000 (95% CI 14.66–14.87) in very high COI areas (incidence rate ratio 1.8; 95% CI 1.78–1.81). Decreasing neighborhood opportunity was associated with increasing hospitalization rates among children in 18 US states. These data underscore the importance of social context and community‐engaged solutions for health systems aiming to eliminate care inequities.
