Validation of the German version of the Perceived Cohesion Scale.

Team or group cohesion is a multifaceted construct with a variety of definitions and measurement instruments. However, most of these measures are context and group-specific and/or time-consuming. There is no adaptable and economic measure of group cohesion in Germany. Therefore, the aim of this study was to validate the German version of the 6-item Perceived Cohesion Scale (PCS) in a sample of adult nurses in a German University Hospital. The German version of the PCS was generated according to existing guidelines. Confirmatory factor analysis was conducted to assess factor structure. Reliability was tested via internal consistency. To assess convergent and divergent validity, the authors applied the Copenhagen Psychosocial Questionnaire (COPSOQ), the Enhancing Recovery in Coronary Heart Disease Patients (ENRICHD) Social Support Inventory (ESSI), the Effort-Reward Imbalance (ERI) scale and the Patient Health Questionnaire (PHQ-4). The confirmatory factor analysis confirmed a 2-factor structure. Psychometric properties of the German PCS prove satisfactory. Internal consistency was excellent for the whole scale (α = 0.95), as well as for both subscales: sense of belonging (SOB) (α = 0.94) and morale (MOR) (α = 0.93). Moderate to strong correlations with the subscales of COPSOQ (Kendall's Tau (τ) = 0.239 - 0.471) indicated very good convergent validity. Regarding divergent validity, the correlations of the PCS subscales and the PHQ-4 were low (τ = -0.109-[-0.143]), as were the correlations with ESSI (τ = 0.045-0.136). Correlations with ERI were low to moderate (τ = -0.181-0.283). The German version of the PCS showed good psychometric properties. Due to its economic and universal deployment, group cohesion can be measured in a variety of contexts and settings. Int J Occup Med Environ Health. 2024;37(4).

An Update of the Promise of Glycine Supplementation for Enhancing Physical Performance and Recovery.

Glycine, the simple amino acid, is a key component of muscle metabolism with proven cytoprotective effects and hypothetical benefits as a therapeutic nutrient. Cell, in vitro, and animal studies suggest that glycine enhances protection against muscle wasting by activating anabolic pathways and inhibiting proteolytic gene expression. Some evidence indicates that glycine supplementation may enhance peak power output, reduce lactic acid accumulation during high-intensity exercise, and improve sleep quality and recovery. This literature review critically explores glycine's potential as an ergogenic aid and its relevance to muscle regeneration, muscle strength, endurance exercise performance, and sleep quality. It also underscores key areas for future research. It is concluded that more randomized controlled clinical trials in humans are needed to confirm glycine's potential as a dietary supplement to support muscle function, recovery, and overall athletic performance as an ergogenic aid and to establish nutritional recommendations for athletic performance. Also, it is essential to consider that high doses (>500 mg/kg of body mass) could induce cytotoxic effects and contribute to acute glutamate toxicity.

The Clinical Effectiveness of Transcutaneous Electrical Nerve Stimulation on Enhancing Recovery after Cesarean Section: A Systematic Review and Meta-Analysis

Background: The transcutaneous electrical nerve stimulation TENS was used following several surgical procedures involving gynecological ones and has shown a successful pain reduction rate. TENS was proposed to enhance recovery after cesarean section CS. Objective: This systematic review and meta-analysis were conducted to evaluate the clinical effectiveness of Transcutaneous electrical nerve stimulation TENS in enhancing recovery after a cesarean section. Methods: We performed the Meta-analyses using RevMan software. Data were pooled as mean difference (MD) if continuous and risk ratio (RR) if dichotomous, and the 95% confidence interval (CI) as calculated. Results: This systematic review included 12 RCTs, with a total of 1,116 women studied. The TENS effectively reduced the intensity of pain just by following its application (SMD=-0.61; 95% CI [-0.82, -0.39], P<0.00001), one day after (SMD=-0.25; 95% CI [-0.47, -0.04], P=0.02), and two days after (SMD=-0.27; 95% CI [-0.50, -0.03], P=0.03). Conclusion: The TENS effectively reduces the pain intensity following its application and after one or two days. TENS has no effect on the cumulative dose of diclofenac. Because of the inadequacy of safety data, we recommend conducting further RCTs.

Enhancing recovery of gold(III) from hydrochloric acid solutions using gemini surfactant microemulsions: The effect of spacer group

The recovery of precious metals from waste has garnered significant attention owing to their non-renewable nature and essential role in the burgeoning information industry. However, enhancing the extraction efficiency of microemulsions remains a significant challenge. In this study, three water-in-oil microemulsions were formulated using gemini surfactants with different spacers (14-OH-14, 14-SO4-14, and 14-3-14) as emulsifiers, supplemented with n-butanol as a cosurfactant, n-heptane as the oil phase, and NaCl aqueous solution as the internal aqueous phase. These microemulsions were employed for the extraction of gold(III) from hydrochloric acid solutions. The results illustrate that all three microemulsions effectively extracted gold(III) through a spontaneous, exothermic, enthalpy-driven anion-exchange mechanism, achieving notable extraction efficiency. In contrast to 14-3-14, incorporating –OH into the spacer significantly augments the positive electrostatic potential through the cationization of –OH in an HCl solution, resulting in a higher binding constant (2.43) and thereby improving the extraction efficiency. However, the presence of −SO4 diminishes the positive electrostatic potential through partial neutralization, resulting in a lower binding constant (1.17), which is detrimental to the extraction process. Response surface optimization revealed that concentrations of C(14-OH-14) and V(1-butanol) significantly influence extraction efficiency and exhibit pronounced interaction. At optimal conditions (C(14-OH-14) = 0.09 mol·L−1, V(1-butanol) = 47.41 %, R=20, and C(NaCl) = 1.57 mol·L−1), over 95.54 % of gold(III) can be extracted from actual e-waste solutions. This study offers an alternative approach for designing or selecting surfactants in microemulsion-based extraction of gold(III) from e-waste.

Association of social support and health status outcomes in peripheral artery disease

ObjectiveA critical goal in the care of patients with peripheral artery disease (PAD) is to optimize their health status; that is, their symptoms, function, and quality of life. Social support has been proposed to be a predictor of disease-specific health status in patients with PAD. However, the prevalence of low perceived social support, the association with health status outcomes, and the interaction with other biopsychosocial variables, is unknown. Our aim was to assess the association of baseline perceived social support with health status at 12 months in patients with PAD. MethodsThe Patient-Centered Outcomes Related Treatment Practices in Peripheral Arterial Disease: Investigating Trajectories (PORTRAIT) registry, which enrolled patients with PAD in the United States, the Netherlands, and Australia from 2011 to 2015, was used. Perceived social support was assessed at baseline with the Enhancing Recovery in Coronary Heart Disease Patients (ENRICHD) Social Support Inventory (ESSI), and disease-specific (Peripheral Artery Disease Questionnaire [PAQ]) and generic health status (Euro-Quality of Life Visual Analog Scale [VAS] and EQ-5D-3L Index) questionnaires were assessed at baseline and 12 months. Low social support was defined as a score of ≤3 on two items and an ESSI score of ≤18. A hierarchical mixed level linear regression model adjusting for biopsychosocial variables was used to assess the association between low perceived social support and the ESSI score with health status at 12 months. ResultsA total of 949 patients were included (mean age, 67.64 ± 9.32 years; 37.9% female), with low social support being present in 18.2%. Patients with low social support were more likely to not be married or to be living alone (50.0% vs 77.5%; P < .001); have more financial constraints; have more depressive, stress, and anxiety symptoms; and have lower disease-specific and generic health status at baseline and at 12 months. In the unadjusted model, low social support was associated with a −7.02 (95% confidence interval [CI], −10.97 to −3.07) point reduction in the PAQ, −7.43 (95% CI, −10.33 to −4.54) in the VAS, and −0.06 (95% CI, −0.09 to −0.03) in the EQ-5D-3L Index. Adjusting for biopsychosocial factors minimally attenuated these associations (PAQ: −6.52; 95% CI, −10.55 to −2.49; P = .002; VAS: −5.39; 95% CI, 8.36 to −2.42; P < .001; EQ-5D-3L Index: −0.04; 95% CI, −0.07 to 0.01; P = .022). The ESSI per-point score was associated with a decrease of 0.51 (95% CI, 0.18-0.85; P = .003) in PAQ and 0.46 (95% CI, 0.12-0.61; P = .004) in the VAS. ConclusionsAmong patients with PAD, low social support was frequent and associated with a lower health status at 1 year independent of other biopsychosocial variables. Improving social support could improve health status and outcomes in PAD.

Enhancing recovery in post-earthquake adolescents: examining the impact of a psychoeducational intervention on traumatic stress symptoms and coping strategies

Adolescents exposed to natural disasters are among the most vulnerable groups to the devastating effects of these events, including experiencing mental health issues such as Post-Traumatic Stress Disorder (PTSD), depression, and anxiety disorders. The study aims to evaluate the impact of an early-term psychoeducational intervention (2 months after the disaster) on adolescents who were exposed to the February 6th earthquakes in Turkey regarding symptoms of post-traumatic stress disorder (PTSD), depression, anxiety, and coping styles. The study employed AB experimental design with a single-group, pre-test, post-test, and follow-up test evaluation. The sample consisted of 8 individuals aged between 12 and 18, relocated to another city (Istanbul) with their families to a container camp after exposure to the earthquake. Participants underwent an 8-session (one session per week) psychoeducational program developed by researchers composed of psychologists 2 months after the earthquake. To assess the effectiveness of the psychoeducational intervention, the Child and Adolescent Post-Traumatic Stress Disorder Reaction Index, Brief Symptom Inventory, and Coping Styles Scale-Brief Form was employed at three different time points (pre-intervention, post-intervention, and 4-month follow-up). Percentage distribution and the Friedman Test for comparisons were done for the data to be analyzed. Following the psychoeducational intervention, a statistically non-significant decrease in depression symptoms was observed, but the effect of the intervention was maintained over the 4-month follow-up period. While no change in anxiety symptoms was noted after the intervention, a significant decrease was observed in the follow-up. However, no improvement was observed in PTSD symptoms. Participants showed a statistically significant increase in religious coping, whereas a non-significant increase in planning, using emotional social support, and positive reinterpretation coping styles were observed. After large-scale disasters affecting numerous individuals, early psychological interventions should be planned and tailored for specific groups and specific needs instead of including every member of the group would be more time and cost-efficient.

Enhancing recovery and reducing readmissions: The impact of remote monitoring on acute postoperative care in outpatient total joint arthroplasty

IntroductionOutpatient total joint arthroplasty (TJA) is gaining popularity in the United States. With a shift towards value-based healthcare and bundled payment models, the importance of safe discharge after TJA is pertinent in reducing readmissions and subsequent cost of care. However, many acute issues or complications may not occur until after discharge which can result in emergency department visits and readmission. Our study aims to characterize the effect of remote monitoring devices on acute postoperative recovery in TJA discharged within 24 h. We hypothesized there would be a decreased readmission rate in the remote home monitoring cohort. MethodsThis prospective cohort compared 50 outpatient TJAs (primary total hip and total knee replacements) defined as discharged within 24 h with a remote home monitoring device to 50 outpatient TJAs who did not receive remote monitoring. Demographics, hospital length of stay, American Society of Anesthesiology scores, and Charlson Comorbidity Index were compared with no significant difference observed between cohorts (p > 0.05). Patients’ vital signs were transmitted to a virtual response center for up to 48 h after discharge. An on-call medical team reviewed the transmissions and if prompted, would contact the patient to troubleshoot and triage. Primary outcome was 30-day hospital readmissions rates, while 30-day ED visits and patient satisfaction scores for the remote home monitoring were measured as secondary outcomes. ResultsWithin the remote monitoring cohort there was a 20 % incidence (10 patients) of abnormal vitals captured and 2 patients visited the ED, however there were no readmissions attributed to this group. Readmission rates and ED visits in the control non-monitored group were significantly higher at 12 % (p = 0.03), secondary to syncope, uncontrolled postoperative pain, cellulitis, hip dislocations, and postoperative fever. Of the patients who received remote monitoring, 14 % had trouble connecting the device to their smartphone, 44 % felt home monitoring helped in their care while recovering at home, 52 % made them feel safer, and 70 % would recommend this program. ConclusionsRemote home monitoring with a virtual response team after outpatient TJA is a feasible way to mitigate readmissions in the acute postoperative period and increase patient satisfaction. Efforts to minimize costs should not be implemented at the expense of patients’ health outcomes with a goal to find an appropriate balance between both agendas.

Quantitative characterization of 3D pore structures and percolation characteristics in bioturbated reservoir media based on X-ray micro-CT: a case study of the Neogene Sanya Formation in the Qiongdongnan Basin, Northern South China Sea

Organisms alter the primary texture of sediments, leading to alteration in petrophysical properties mediated by a textural and mineralogical contrast between burrow-fill and sediment host, which affects reservoir properties and fluid flow characteristics. In this article, in order to understand the microscopic pore structure and flow state of fluids in microscopic pores of bioturbated reservoirs, Ophiomorpha-bearing bioturbated reservoirs in the Neogene Sanya Formation of the Qiongdongnan Basin in the northern South China Sea were selected to research. Micro-CT was applied to scan selected core plugs, and a 3D pore structure model was established. The geometric characteristics of the microscopic pore structure were quantitatively and visually characterized by a modified maximal ball algorithm, and connectivity analysis of the pore structure was carried out. Numerical simulations of the percolation characteristics of the analyzed bioturbated reservoir samples were performed using digital core software (Avizo) and multi-physics field simulation software (Comsol). The results show that: (1) 3D pore structures reveal that pore volume, pore area, pore equivalent radius, throat area, throat equivalent radius and throat length have a large distribution range; among them, the pore volume has the largest distribution range, which can vary by six orders of magnitude, indicating that the pore size distribution of the bioturbated reservoir is uneven and has strong heterogeneous characteristics; (2) the connected pore structure is very complex, and as the equivalent radius of connected pore increases, the coordination number also gradually increases, the better the connectivity. Numerical percolation simulation results also suggested that larger connected pore space plays a key role in the effective permeability of the reservoir. This study has important implications for analyzing the modification effect of bioturbation on oil and gas reservoirs, and enhancing production and recovery in the study area.

The roles of health literacy and social support in the association between smartphone ownership and frailty in older adults: a moderated mediation model

BackgroundUnderstanding the role of smartphones to promote the health status of older adults is important in the digital society. Little is known about the effects of having smartphones on physical frailty despite its positive effect on the well-being of older adults. This study aimed to explore the association between smartphone ownership and frailty in community-dwelling older adults and its underlying mechanism.MethodsWe used data from the Korean Frailty and Aging Cohort Study and analyzed 2,469 older adults aged 72–86 years. Frailty, health literacy, and social support were assessed by Fried’s frailty phenotype, the Behavioral Risk Factor Surveillance System health literacy module, and the Enhancing Recovery in Coronary Heart Disease (ENRICHD) Social Support Instrument, respectively. The mediation model and moderated mediation model were estimated, where the mediator was health literacy and the moderator was social support, to explore the relationship between smartphone ownership and frailty.ResultsOf our study participants, 58.9% owned smartphones, and 10.9% were classified as frail. Smartphone ownership was negatively associated with frailty (β = −0.623, p < 0.001). Health literacy mediated the relationship between smartphone ownership and frailty (β = −0.154, boot confidence interval [CI] = − 0.222, − 0.096), and social support moderated the mediation effect (β = −0.010, Boot CI = − 0.016, − 0.004).ConclusionsOwning smartphones among older adults could reduce the risk of frailty. Promoting health literacy and social support among older adults with smartphones would be effective to prevent frailty.

Enhancing Recovery of Ultra-Fine Magnetite from Low-Iron-Grade Cyanidation Tailings by Optimizing Flow Field Parameters of Low-Intensity Magnetic Separation (LIMS)

The characteristics of iron minerals in cyanidation tailings with a low iron grade were determined via chemical composition analysis, iron phase analysis, and mineral liberation analysis (MLA). The results showed that the cyanidation tailings contained 15.68% iron, mainly occurring in the form of magnetite (19.66%) and limonite (79.91%), in which 16.52% magnetite and 65.90% limonite particles were fully liberated. Most ultra-fine magnetite grains were adjacent and wrapped with limonite to form complex intergrowths, which resulted in low-efficiency magnetite recovery in low-intensity magnetic separation (LIMS) and adversely affected the downstream high-gradient magnetic separation (HGMS) process. Thus, in this work, the optimization of the flow field was proposed to enhance the separation of ultra-fine magnetite from the cyanidation tailings using pilot-scale LIMS separation, and the controllable parameters (including feed flow, separation gap, drum rotating speed, and solid weight) affecting ultra-fine magnetite capture were investigated. Under optimized conditions, a high-grade magnetite concentrate assaying 63.31% Fe with 86.46% magnetite recovery was produced, which, respectively, increased by 0.76% and 15.22%, compared with those obtained from industrial production. In addition, from the flow dynamics simulation, it was found that the magnetite particles in the −6 µm ultra-fine fraction were lost much more easily than those of coarser fractions due to the relatively enhanced hydrodynamic drag force acting on the particles compared with the magnetic force. However, this loss would be effectively reduced with the regulation and control of the flow field. The iron recoveries in the −16~+6 µm and −6 µm fractions of magnetite concentrate increased by 3.66% and 4.42%, respectively, under optimized hydrodynamic conditions. This research outcome provides a valuable reference for the economic and effective utilization of iron resources from such solid wastes.

Data-driven personalized medicine approaches to cognitive-behavioral therapy allocation in a large sample: A reanalysis of the ENRICHED study

BackgroundAlthough effective treatments for common mental health problems are available, individual responses to treatments are difficult to predict. Treatment efficacy could be optimized by targeting interventions using individual predictions of treatment outcomes. The aim of this study was to develop a prediction algorithm using data from one of the largest randomized controlled trials on psychological interventions for common mental health problems. MethodsThis is a secondary analysis of the Enhancing Recovery in Coronary Heart Disease study investigating the effectiveness of cognitive behavioral therapy (CBT) and care as usual (CAU) for depression and low perceived social support following acute myocardial infarction. 2481 participants were randomly assigned to CBT and CAU. Baseline social-demographics, depression characteristics, comorbid symptoms, and stress and adversity measures were used to build an algorithm predicting post-treatment depression severity using elastic net regularization. Performance and generalizability of this algorithm were determined in a hold-out sample (n = 1203). ResultsTreatment matching based on predictions in the hold-out sample resulted in inconsistent and small effects (d = 0.15), that were more pronounced for individuals matched to CBT (d = 0.22). We identified a small subgroup of individuals for which CBT did not appear more efficacious than CAU. LimitationsLimitations are a poorly defined CAU condition, a low-severity sample, specific exclusion criteria and unavailability of certain baseline variables. ConclusionsSmall matching effects are likely a realistic representation of the performance and generalizability of multivariable prediction algorithms based on clinical measures. Results indicate that future work and new approaches are needed.

Predictors of Adherence and Response to Exercise Interventions in Schizophrenia

Abstract Exercise can be considered a feasible and efficient add-on treatment in schizophrenia. However, there remain two major challenges with regard to feasibility and efficiency: First, drop-out rates during exercise programs appear to be relatively high, ranging between 30 to 80 percent. Second, only between 30 and 50 percent of patients clinically respond to exercise interventions. Hence, we aimed to identify factors that predict adherence and response to exercise programs in people with schizophrenia. Based on data from 180 patients with schizophrenia enrolled in the Enhancing Schizophrenia Prevention and Recovery through Innovative Treatments (ESPRIT) C3 study, we examined clinical baseline characteristics that may predict study completion and number of attended trainings (adherence), as well es clinically relevant improvements in symptomatology and functioning (response). We found that only levels of functioning at baseline, but not symptom severity, cognitive functioning, or physical health, predicted adherence. Further, we provide preliminary evidence suggesting that patients with higher cognitive abilities and higher education who performed regular exercise already prior to the study participation were more likely to respond. To conclude, our findings indicate that exercise is particularly helpful for a subgroup of patients characterized by higher levels of functioning, higher cognitive abilities and education, and more pronounced affinity to exercise. Future studies should additionally include environmental, genetic, and neural data to predict adherence and response to exercise.Disclosure of InterestNone Declared

Effectiveness of Art Therapy Programs in Enhancing Recovery and Rehabilitation in Sports Medicine

Purpose: The general aim of the study was to examine the effectiveness of art therapy programs in enhancing recovery and rehabilitation in sports medicine.&#x0D; Methodology: The study adopted a desktop research methodology. Desk research refers to secondary data or that which can be collected without fieldwork. Desk research is basically involved in collecting data from existing resources hence it is often considered a low cost technique as compared to field research, as the main cost is involved in executive’s time, telephone charges and directories. Thus, the study relied on already published studies, reports and statistics. This secondary data was easily accessed through the online journals and library.&#x0D; Findings: The findings reveal that there exists a contextual and methodological gap relating to the effectiveness of art therapy programs in enhancing recovery and rehabilitation in sports medicine. Preliminary empirical review revealed that art therapy interventions offer a holistic approach to healing, addressing athletes' physical, emotional, and social needs during the recovery process. Through a comprehensive review of empirical studies, the findings demonstrated consistent positive outcomes, including improved physical function, pain management, psychological well-being, and overall recovery among athletes. The study highlighted the importance of interdisciplinary collaboration and patient-centered care in sports medicine rehabilitation, as well as the potential cost-effectiveness of incorporating art therapy into standard practice. These findings underscored the value of art therapy as a complementary intervention in optimizing athletes' recovery and facilitating their successful return to sport.&#x0D; Unique Contribution to Theory, Practice and Policy: The Social Cognitive theory, Self- Determination theory and Biopsychosocial model may be used to anchor future studies on the effectiveness of art therapy programs in enhancing recovery and rehabilitation in sports medicine. The study provided recommendations that contributed to theory, practice, and policy. The findings emphasized the importance of grounding art therapy interventions in established theoretical frameworks, integrating them into standard rehabilitation protocols, advocating for policy support and reimbursement, fostering collaboration and partnerships, developing standardized protocols and outcome measures, and advancing research and evaluation efforts. These recommendations aimed to optimize the use of art therapy as a holistic and effective intervention for athletes recovering from sports injuries, ensuring equitable access to these services and fostering a culture of innovation in sports medicine rehabilitation.

Disparities in 30-Day Readmission Between Medicare/Medicaid and Private Insurance Among Patients With Heart Failure Screened for Cognitive Impairment.

Racial disparities exist among patients with heart failure (HF). HF is often comorbid with cognitive impairment. Appropriate self-care can prevent HF hospital readmissions but requires access to resources through insurance. Racial differences exist between insurance types, and this may influence the disparity between races and patients with HF and cognitive impairment. The objectives of this study were to examine the relationships between insurance type and self-care stratified by race and to assess for differences in time-to-30-day readmission among patients with HF with cognitive impairment. This is a secondary analysis of data collected among hospitalized patients with HF with cognitive impairment. Patients completed surveys on self-care (Self-Care of Heart Failure Index), HF knowledge (Dutch Heart Failure Knowledge Scale), depression (Geriatric Depression Scale), and social support (Enhancing Recovery in Coronary Heart Disease Social Support Inventory). Socioeconomic data were collected. Linear models were created to examine the relationships between insurance type and self-care by race. Kaplan-Meier curves and Cox regression were used to assess readmission. The sample of 125 patients with HF with cognitive impairment was predominantly Black (68%, n = 85) and male (53%, n = 66). The sample had either Medicare/Medicaid (62%, n = 78) or private insurance (38%, n = 47). Black patients with HF with cognitive impairment and private insurance reported higher self-care confidence compared with Black patients with HF with cognitive impairment and Medicare/Medicaid (P < .05). Medicare/Medicaid was associated with a higher frequency of 30-day readmission and a faster time-to-readmission. Patients with HF with cognitive impairment and Medicare/Medicaid insurance reported lower self-care confidence and more likely to be readmitted within 30 days.

Enhancing Recovery Yield of Vegetable Oil Methyl Ester for Bioresin Production: A Comparison Study Using Acid Neutralization

Vegetable oil methyl ester has promising properties for bio-based resin production due to its higher degree of unsaturation. The initial low methyl ester yield from corn oil compared to soybean and canola oils requires further investigation of the influence of neutralization at the end of the transesterification reaction. To evaluate the neutralization effect with HCl, corn, canola, and soybean oil were transesterified using NaOH at 60 °C with a 6:1 methanol–oil ratio. This research also investigated the effect of reaction times (0.5–1.5 h) with varying neutralization levels (0–100%) on the corn oil methyl ester yield. The yield of corn, canola, and soybean methyl ester was increased significantly by 16–25% through neutralization, indicating the positive impact of neutralization. The corn oil methyl ester yield ranged from 45 to 79% across different neutralization levels and reaction times. With 25% neutralization, the yield increased by 20%. On the other hand, the yield reduced by 18–24% over time when there was no neutralization. A statistical model was developed where the yield varied significantly with the acid amount, reaction time, and their interactions. The quality of the corn methyl ester was found to be within the limits of standard pure methyl ester. Overall, the effect of neutralization showed promise in increasing the yield of quality methyl ester from commercial corn oil.

Enhancing Data Backup and Recovery in Cloud Computing with Secure Database Monitoring

The company uses unregistered data to improve performance, but this comes at the cost of limited backup options, data loss, and a voluntarily damaging week-long downtime. Even if they have backup systems, they cannot meet the SLA recovery time. To solve these problems, this work presents a secure database monitoring method for cloud computing. This approach adjusts the backup speed according to the data volume; This is important when data grows at least 30% per year. For the some companies, the data doubles every 3-4 years or more and SLAs and recovery targets need to be updated. At the same time, business needs for data recovery continue to grow, highlighting the need for more robust and responsive data management strategies.

Enhancing nickel grade and recovery with counter-current washing of the concentrated bubbly-zone of a single stage REFLUX™ Flotation Cell

The recovery and concentration of the nickel sulphide mineral, pentlandite, present several challenges due to its relatively slow flotation, leading to excessive hydrophilic gangue minerals in the concentrate. The REFLUX™ Flotation Cell (RFC™) offers the potential for a significant hydrodynamic advantage over conventional flotation. Much of this advantage is due to the replacement of the pulp and froth phases with a concentrated bubbly zone, which in turn supports more intense counter-current washing by permitting a powerful and effective positive bias flux. Thus, the aim of this study was to investigate the nickel recovery and silica rejection in the RFC™, by applying a wide range of positive bias fluxes. The focus was on a single stage of separation in the RFC™ using a feed flux of 0.63 cm/s at a feed nickel grade of 2.1%. At the lowest bias flux of 0.1 cm/s, a nickel grade of 7.5% was obtained at a single stage recovery of 70.2%. By increasing the bias flux to 0.42 cm/s, the grade increased to 9.7% but the recovery fell to 64.9%. With an extreme bias flux of 1.04 cm/s, the grade reached 12.3%, while the recovery fell to 54.7%. The selectivity, given by the nickel recovery relative to the silica recovery, was estimated to be 121 at the highest bias flux, declining sharply with a reduction in the bias flux. The performance ratio proposed by Parkes et al (2022) was quantified by comparing the RFC™ performance with the batch kinetic results from a mechanical cell, the product grade being ∼7%. The performance ratio was based on the experiment at the lowest bias flux used in the RFC™, and found to be at least 6, meaning the RFC™ footprint would be reduced by a factor of ∼6 for a similar product grade. Based on the higher product grades achieved in the RFC™ using the higher positive bias fluxes, the performance ratio would likely exceed 10-fold given the need for the mechanical cell concentrate to undergo at least one further stage of flotation.

Postoperative Nutritional Strategies for Lung Cancer Patients: Enhancing Recovery and Well-Being

Lung cancer is a common and serious malignancy, and dietary management plays a pivotal role in the postoperative recovery process for lung cancer patients. This study explores the nutritional requirements, dietary challenges, and dietary strategies for postoperative lung cancer patients.
