Published: September 2022

Abstract
Geographically Weighted Poisson Regression (GWPR) is a Poisson regression model which is applied on spatial data. The parameter estimation of GWPR is done in each observation location through spatial weighting. This study aims to determine the GWPR model of the number of leprosy cases in each province of Indonesia 2020 and to find the influencing factors. The research uses secondary data collected from Indonesian Ministry of Health and Central Statistics Agency. The spatial weighting is calculated by using the adaptive bisquare function, while the optimum bandwidth is determined by using Generalized Cross-Validation criteria (GCV). The parameter estimation of GWPR uses Maximum Likelihood Estimation (MLE) method. The result of research show that the closed form of Maximum Likelihood (ML) estimator can not be found analytically and that the approximation of ML estimator is found by using Newton-Raphson iterative method. Based on the parameter significance test of the GWPR model, the factors that influenced the number of leprosy cases locally are the percentage of households that have access to proper sanitation, population density, the percentage of people who experience health complaints and outpatient, the number of health workers, the percentage of poor people, the percentage of districts/cities that carry out healthy living community movement (GERMAS) and the percentage of habitable houses. While the factors that globally affected the number of leprosy cases are the percentage of households that have access to proper sanitation, population density, the percentage of people who experience health complaints and outpatient, the number of health workers, the percentage of poor people, the percentage of districts/cities that carry out GERMAS.

Methane Diffusion Through Nanopore-Throat Geometry: A Molecular Dynamics Simulation Study
Authors: Sun Runxuan , Xu Ke , Huang Tianjia , Zhang Dongxiao 
Published: September 2022

SummaryMolecular diffusion dominates over pressure-driven convection as the major mass transport mechanism in nanoporous media with &lt;10-nm pores, which is typical pore size for shale gas recovery. To study fluid behavior at this scale, molecular dynamics (MD) simulation has been widely applied. Nevertheless, classic capillary tube or slit models are of uniform geometry that miss the converging-diverging pore-throat feature, while more realistic models lose simplicity and generality.In this work, we propose a novel geometric model that can reproduce the realistic converging-diverging structure in subsurface porous media without any additional complexity compared to classic slit or capillary models. In this pore-throat model, we are able to identify how nonuniform geometry affects the methane diffusion for both pure methane and for methane mixtures with water, carbon dioxide, and helium.For a pure methane system, we demonstrate the fundamental impact of throat width on diffusion coefficient when the throat width is narrower than 20 Å and identify a critical throat width that determines whether methane can self-diffuse though the throat. This critical throat size is regulated by the energy barrier at the throat rather than by molecular size. We then introduce a semianalytical model to predict self-diffusion coefficient as a function of pressure, temperature, and throat width.For mixtures, we observe the key impact of spatially nonuniform fluid distribution in determining diffusion. Water or carbon dioxide can locally concentrate at the throat, which reduces methane diffusivity, while helium prefers to stay in the pore body, which mildly enhances methane diffusivity. Specifically, although residual water reduces methane diffusion (26% reduction for 20% water molar fraction), it completely blocks the throat and thus prohibits pressure-driven methane convection. By comparison, the dominance of molecular diffusion over convection can be extended to larger pores in presence of residual water. It provides an explanation on shale gas production when connate water is expected to block the flow path.
Using mathematical research methods for analyzing environmental and economic prospects of the Russian arctic oil and gas producing shelf projects

Published: September 2022

Objective: to study the ecological and economic prospects of Russian Arctic oil and gas offshore projects by the method of functional analysis.Methods: mathematical modeling, comparative analysis, empirical analysis.Results: a method is proposed for assessing the financial provision of measures to eliminate the alleged environmental damage caused by hydrocarbon spills in Arctic offshore oil and gas production projects; models of oil spills in the “Prirazlomnoye” and “Pobeda” Arctic offshore fields are considered; the cost of measures to eliminate these incidents is estimated.Scientific novelty: for the first time, the paper investigates the function of financial provision for measures to eliminate the alleged environmental damage due to hydrocarbons spills at the “Prirazlomnoye” and “Pobeda” Arctic offshore oil and gas fields with the mathematical method of functional analysis, calculation of the maximum costs, as well as the time from the start of the spill, which accounts for these functional values. The assumption of the mathematical model is the hypothesis of the constancy of the well flow rate (the top estimate is the characteristic flow rate of the per second production of the entire field), as well as the neglect of changes in the physical properties of liquid hydrocarbons (viscosity, density) due to the characteristic annual temperature dynamics of the Arctic regions and consideration of the dynamics of the oil spill spread on the sea surface in the inert phase without taking into account the gravitationally viscous and surface modes.Practical significance: the mathematical modeling data on spills can be used by insurance companies in the calculation of insurance premiums, by Rosprirodnadzor Agency in the calculation of fines, and by other supervisory agencies in the underwriting of oil and gas Arctic projects.

Abstract
Objective
This paper aims to explore the influence of family function, work engagement, and sleep on the mental health of nurses in China's top three hospitals.
Method
The convenience sampling method was adopted to select 1147 clinical nurses from Taihe Hospital Affiliated to Hubei University of Medicine, during the period of August-September 2018 as the survey subjects. APGAR, UWES-9, PSQI,SCL-90 were employed to conduct a questionnaire survey on nurses’ family function, work engagement, sleep quality, and mental health status. Correlation analysis was performed to explore the relationship between clinical nurses’ mental health and family function, work engagement, and sleep quality. Multiple linear regression analysis and structural equation model were adopted to analyze the influencing factors of clinical nurses' mental health.
Results
Multiple linear regression analysis demonstrated that the main influencing factors of clinical nurses’ mental health include the length and emotional degree of family function, sleep quality, and the vitality dimension in work engagement (with t values of 1.996, -3.313, 17.524, and − 2.571, respectively, P < 0.05).
Conclusion
The clinical nurses have good family function, sleep quality, and mental health status, and the level of work engagement is average. Besides, work engagement is closely related to mental health.

Abstract
Drought indices have been commonly used in drought monitoring and assessments, but selecting the most appropriate one under different geographical and climatic conditions is difficult. We constructed a multi-timescale integrated drought index, the Ensemble Drought Index (EDI), for more robust and reliable drought assessments with the widely used Standardized Precipitation Index (SPI), the Palmer Drought Severity Index (PDSI), the self-calibrated Palmer Drought Severity Index (scPDSI), and the Standardized Precipitation Evapotranspiration Index (SPEI) using the Thornthwaite and the Penman-Monteith methods. The EDI can more accurately describe the major historical drought events, and has high and significant correlation with historical monthly soil moisture and annual runoff data all over China, regardless of regional differences. in region among those indices participating in integration. We also showed that the EDI greatly improved monitoring accuracy in the arid and semi-arid regions of China, where the assessments are always thorny. In the meantime, we revealed how the reference period of fitting statistical parameters affects the accuracy of drought assessments, and concluded that the long-term stationary climate variables series (i.e., without trend) can bring more accurate conclusions.

Published: September 2022

Abstract
In order to keep the home and occupational environment clean and noninfectious, the consumption of the cleaners and disinfectants, including cosmetics, is increasing. Excessive use of the products results in their accumulation in an aquatic environment. The conventional wastewater treatment plants are unable to effectively remove the emergent pollutants, including the personal care products. The article is focused on the monitoring the presence of the personal care products in surface waters in two river basins in the Slovak Republic, in terms of the surfactant content. Ecotoxicological evaluation of the selected samples from monitored river basins is performed by an acute toxicity test using the test organism Daphnia magna. The monitoring results indicate the presence of the personal care products in the aquatic environment, where pose an ecological and environmental risk. Monitoring in the Hron and Nitra river basins confirmed contamination with the surfactants, to which the measures related to the COVID-19 pandemic contributed. The content of the surfactants in the personal care products is significant and their impact on the aquatic environment is not sufficiently monitored.

Authors: Herman Alexander , Duraiswamy Nandini , Nandy Poulomi , Price Veronica , Gibeily George , Hariharan Prasanna 
Published: September 2022

Abstract
Background:

Tissue containment systems (TCS) are medical devices that may be used during morcellation procedures during minimally invasive laparoscopic surgery. TCS are not new devices but their use as a potential mitigation for the spread of occult malignancy during laparoscopic power morcellation of fibroids and/or the uterus has been the subject of interest following reports of upstaging of previously undetected sarcoma in women who underwent a laparoscopic hysterectomy. Development of standardized test methods and acceptance criteria to evaluate the safety and performance of these devices will speed development, allowing for more devices to benefit patients.

Methods:

As a part of this study, a series of preclinical experimental bench test methods were developed to evaluate the mechanical and leakage performance of TCS that may be used in power morcellation procedures. Experimental tests were developed to evaluate mechanical integrity, e.g., tensile, burst, puncture, and penetration strengths for the TCS, and leakage integrity, e.g., dye and microbiological leakage (both acting as surrogates for blood and cancer cells) through the TCS. In addition, to evaluate both mechanical integrity and leakage integrity as a combined methodology, partial puncture and dye leakage was conducted on the TCS to evaluate the potential for leakage due to partial damage caused by surgical tools.
Samples from 7 different TCSs) were subjected to preclinical bench testing to evaluate leakage and mechanical performance.

Results:

The performance of the TCSs varied significantly between different brands. The leakage pressure of the TCS varied between 26 mmHg and >1293 mmHg for the 7 TCS brands. Similarly, the tensile force to failure, burst pressure, and puncture force varied between 14 MPa and 80 MPa, 2.5 and 78 psi, and 2.5 N and 45 N, respectively. The mechanical failure and leakage performance of the TCS were different for homogeneous and composite TCSs.

Conclusions:

Test methods have been developed to evaluate the mechanical and leakage performance of TCS. These test methods may facilitate the development and regulatory review of these devices, may help compare TCS performance between devices, and increase provider and patient accessibility to improved tissue containment technologies.

Abstract
This cross-sectional study was conducted to determine and compare the concentrations of heavy metals (Zn, Pb, Cd, and Hg) in carp-farming water and muscle of various carp species including common carp ‎‎(Cyprinus carpio), bighead carp (Hypophthalmichthys nobilis), silver ‎carp ‎‎(Hypophthalmichthys ‎molitrix) and grass carp (Ctenopharyngodon idella) collected from three major warm-water fish farms in ‎Mazandaran Province (Iran) during March 2018 to March 2019. In addition, bioaccumulation of heavy metals (BCFs), and carcinogenic and non-carcinogenic risk assessments of consumers exposed to heavy metals through fish consumption were estimated. The water concentration of all metals in this study was lower than permissible limits. The ‎concentration of Zn in the water (10.21–17.11 µg.L− 1) was higher than that of other metals in all ‎sites, followed by Pb > Cd > Hg.‎ In fish muscle, Zn concentration in silver carp was the highest, and the lowest concentrations were related to Hg and Cd in common carp and grass carp, respectively. The target hazard quotients (THQ) indicated that the non-carcinogenic health risk to humans was relatively low by consuming four farmed carp species products. The carcinogenic risk of inorganic Pb was ‎1.24E-04 (common carp) to 2.11E-04 (grass carp) for adults‎, which is within the acceptable range. The values of BCFs for all metals demonstrated that farmed carp muscle could not be considered a bioaccumulative tissue for heavy metals. The results indicated that the concentrations of heavy metals in the farmed carp species in North Iran were relatively low, and did not cause considerable human health risks.

Published: September 2022

AbstractEnvironmental conditions and temperature oscillations can influence wood properties. Accordingly, the performance of wood connections such as nails could be affected by freezing and heating temperature. Thus, in the present work, the impact of freezing/heating temperatures on the nail withdrawal power of Norway Spruce (Picea abies(L.) H. Karst.) and European Larch (Larix deciduaMill.) has been studied. Three types of the wood nail; smooth, helically threaded, and annularly threaded were studied, and two different freezing heating steps have been implemented (-15°C/70°C and − 25°C/70°C). Withdrawal capacity was distinguished on two various anatomical directions; radial and tangential surfaces. The freezing could cause a considerable destructive impact on the nail withdrawal capacity of both wood species. The highest drop has found for smooth nail (A) for larch wood in the tangential direction with 73% and 69% decrease and radial direction, with 70% and 63%, at temperatures − 15°C/70°C and − 25°C/70°C, respectively. Furthermore, spruce wood exhibited a meaningful reduction for both tangential (69% and 63%) and radial (54% and 56%) directions and smooth nail (A), at temperatures − 15°C/70°C and − 25°C/70°C, respectively. The highest reduction was found for annularly threaded nails (C).
Conceptualising engagement with HIV care for people on treatment: the Indicators of HIV Care and AntiRetroviral Engagement (InCARE) Framework

Published: September 2022

Abstract

Background

As the crisis-based approach to HIV care evolves to chronic disease management, supporting ongoing engagement with HIV care is increasingly important to achieve long-term treatment success. However, ‘engagement’ is a complex concept and ambiguous definitions limit its evaluation. To guide engagement evaluation and interventions to improve HIV outcomes, we sought to identify critical, measurable dimensions of engagement with HIV care for people on treatment from a health service-delivery perspective.

Methods

We used a pragmatic, iterative approach to develop a framework, combining insights gained from researcher experience, a narrative literature review, framework mapping, expert stakeholder input and a formal scoping review of engagement measures. These inputs helped to refine the inclusion and definition of critical elements of engagement behaviour that could be evaluated by the health system

Results

The final framework presents engagement with HIV care as a dynamic behaviour that people practice rather than an individual characteristic or permanent state, so that people can be variably engaged at different points in their treatment journey. Engagement with HIV care for those on treatment is represented by three measurable dimensions: ‘retention’ (interaction with health services), ‘adherence’ (pill-taking behaviour), and ‘active self-management’ (ownership and self-management of care). Engagement is the product of wider contextual, health system and personal factors, and engagement in all dimensions facilitates successful treatment outcomes, such as virologic suppression and good health. While retention and adherence together may lead to treatment success at a particular point, this framework hypothesises that active self-management sustains treatment success over time. Thus, evaluation of all three core dimensions is crucial to realise the individual, societal and public health benefits of antiretroviral treatment programmes.

Conclusions

This framework distils a complex concept into three core, measurable dimensions critical for the maintenance of engagement. It characterises elements that the system might assess to evaluate engagement more comprehensively at individual and programmatic levels, and suggests that active self-management is an important consideration to support lifelong optimal engagement. This framework could be helpful in practice to guide the development of more nuanced interventions that improve long-term treatment success and help maintain momentum in controlling a changing epidemic.
