<title>Abstract</title> The management of sludge waste remains a critical challenge, as improper disposal can contaminate soil and water sources, impacting ecosystems and human health. In this study, polyaluminum chloride (PACl), coagulant was used to enhance the capturing process of domestic sludge waste using surface-active natural rubber latex (NRL) films. The NRL films were manufactured using the compounding and curing methods. The surface-active NRL film facilitated sludge removal by utilizing electrostatic interactions between the film and sludge particles. The incorporation of coagulant increased the sludge particle size and reduced the zeta potential of sludge water, enhancing aggregation. FTIR analysis confirmed the presence amines, proteins and peptides on the NRL film surface after the capturing process, indicating the captured sludge on the surface. The sludge deposition on the NRL films surfaces is more pronounced when the coagulant was incorporated. These findings demonstrate the effectiveness of surface-active NRL films in sludge waste removal, highlighting their potential for water treatment applications.

Our perspective piece does not include a formal abstract; however, it addresses key topics such as the transition from undergraduate studies to an industry career, the challenges associated with this new phase of life, and the strategies we have developed to emphasize work-life balance and personal fulfillment

To examine the association between local health department (LHD) accreditation and COVID-19 community outcomes, including rates of adult vaccination, hospitalization, and death. We examined county level rates of adult vaccination, hospitalization, and death by LHD accreditation status over the course of the COVID pandemic. Additional independent variables included time period, COVID-19 Community Vulnerability Index (CCVI), state public health governance structure, and state policy environment. We used hierarchal linear mixed modeling with random intercept for county level data to account for repeated observations and fixed effects for all other variables. This study examined all communities in the United States of America. LHDs and the communities they serve. Rates of adult vaccination, hospitalization, and death due to COVID-19. Among accredited LHDs, the adult population was more likely to be fully vaccinated when compared to unaccredited LHDs ( P <.01). Additional variables in the model, which were also significant, included time period, CCVI, state policy environment, and state public health governance structure. There were no significant differences in the hospitalization rates in jurisdictions with an accredited LHD compared to jurisdictions where the LHD is not accredited. Death rates in jurisdictions with an accredited LHD were statistically significantly lower than death rates in jurisdictions where the health department was not accredited ( P <.001). This relationship was significant with other key variables in the model, including time, CCVI, state policy environment, and state public health governance structure. This study demonstrates that there is an association between LHD accreditation and community health outcomes. Furthermore, we found that other factors, such as social determinants of health, state policy environment, and state public health governance structure impact community health outcomes.

The purpose of this study was to examine the physical and genetic variations of ants at a former landfill, the Holtsville Wildlife and Ecology Center (HWEC), to infer if the biodiversity of these organisms, and thus the site, has been influenced by potential pollutants present at the center that could harm humans.Methods of phenotypic and genotypic analysis of the ants were used to understand species diversity at the HWEC.Ants are known as an indicator species, which made them viable organisms for use in this study and to view the impact of pollutants on human health.It was hypothesized that the presence of pollutants at the HWEC would be signaled by low ant biodiversity at different collection locations since biodiversity corresponds to ecosystem stability.Ants were collected from three distinct locations at the HWEC.Out of twenty-seven collected ants, twenty were selected for analysis.Using a silica extraction method, DNA was isolated and sequenced from these specimens.After sequencing, ten samples were removed from consideration due to poor results.Sequencing the ants from site 1 resulted in the species Tetramorium caespitum to be found.Ants from site 2 were the most diverse, containing the species Lasius alienus and Lasius neoniger.At site 3, ants returned as the species Tetramorium immigrans.Considering the entire HWEC's biodiversity, the presence of four species of ants suggests high biodiversity, indicating overall stability.Since approximations of this stability came from ant biodiversity measurements and ants are described as excellent bioindicators, it is defended further, supporting the conclusion that there are no harmful pollutants in the center.This refutes this paper's hypothesis, relieving concerns that the status of this specific center (HWEC) as a landfill-turned-park could cause human health issues, and illustrating that ant biodiversity can be indicative of pollutant presence at former landfills.

Children with weight-for-age z-score (WAZ) <-3 have a high risk of death, yet this indicator is not widely used in nutrition treatment programming. This pooled secondary data analysis of children aged 6-59 months aimed to examine the prevalence, treatment outcomes, and growth trajectories of children with WAZ <-3 versus children with WAZ ≥-3 receiving outpatient treatment for wasting and/or nutritional oedema, to inform future protocols. Binary treatment outcomes between WAZ <-3 and WAZ ≥-3 admissions were compared using logistic regression. Recovery was defined as attaining mid-upper-arm circumference ≥12.5 cm and weight-for-height z-score ≥-2, without oedema, within a period of 17 weeks of admission. Data from 24,829 children from 9 countries drawn from 13 datasets were included. 55% of wasted children had WAZ <-3. Children admitted with WAZ <-3 compared to those with WAZ ≥-3 had lower recovery rates (28.3% vs. 48.7%), higher risk of death (1.8% vs. 0.7%), and higher risk of transfer to inpatient care (6.2% vs. 3.8%). Growth trajectories showed that children with WAZ <-3 had markedly lower anthropometry at the start and end of care, however, their patterns of anthropometric gains were very similar to those with WAZ ≥-3. If moderately wasted children with WAZ <-3 were treated in therapeutic programmes alongside severely wasted children, we estimate caseloads would increase by 32%. Our findings suggest that wasted children with WAZ <-3 are an especially vulnerable group and those with moderate wasting and WAZ <-3 likely require a higher intensity of nutritional support than is currently recommended. Longer or improved treatment may be necessary, and the timeline and definition of recovery likely need review.

In this study, a three-dimensional numerical model of an ejector is established, which is based on a 40 W power proton exchange membrane fuel cell (PEMFC) system. Computational Fluid Dynamics (CFD) technique is used to analyze the ejector in low power condition. The effects of two key structural parameters (distance from the mixing chamber to the nozzle and the mixing chamber diameter) on the ejector performance at different currents are investigated. It is found that ejector entrainment ratio changes slightly with the distance from mixing chamber to nozzle. The ejector entrainment ratio increases first and then decreases with the mixing chamber diameter. Moreover, with the increase of mixing chamber diameter, the turbulent kinetic energy and turbulent dissipation rate decrease obviously.

Abstract The grave challenges of inequality, hunger and poverty are escalating in most of developing countries including India, thereby jeopardizing the overall growth of our country as well as the global economy. Under such crippling situations of poverty and inequality, the magnitude of inefficient and unsystematic lending practices, lack of monitoring by lenders and related fraudulent activities are on the rise, thereby causing a substantial build-up of non-performing assets as one of the emerging risks for the financial sector. The available finance management tools, in fact, lack the capability of real-time execution, fund deployment, credit risk assessment and project viability monitoring. This manuscript describes how a combination of process modeling, execution and measurement can be deployed for assessing financial traceability with accounting, billing, inventory &amp; real-time project tracking and monitoring updates. The explicit process accounts primarily for due diligence framework; controls financial traceability; as well as geo-mapping, fencing &amp; tagging based tangible process assessment of projects prior to lending, during and post implementation. Ultimately, the proposed blockchain secured finance solution (B-Bank™) will cause optimization of credit risk capital at both stages of pre-sanction, pre-disbursement and post implementation of projects, thereby balancing and strengthening the financial institutions and ultimately the global economy.
