Study and analysis of the Chalcolithic Period of the Mughan Plain based on the archaeological data of Yataq-Tepesi, Northwest of Iran
Authors: Karimikiya A. , Rezalou R. , Abedi A. , Javanmardzadeh A. , Mohammadi M.R.
Published: September 2022

The rivers, including Aras, in the Mughan region played an important role in the formation of the prehistoric sites. The Mughan Plain has not received particular attention in terms of the archaeological investigations, as the extensive scientific activities concentrated on the Lake Urmia basin. Yataq-Tepesi is a prehistoric site in the city of Germi (Mughan Region) that became the subject of the scientific research. The main aim of this paper is to discuss the pottery traditions at the site and to determine the chronological sequence of the studied region. In view of further detailed studies on the cultural relations of Mughan population with other territories, and to establish its chronological sequence, two main questions are posed: how do we date Yataq-Tepesi on the basis of cultural information, including pottery traditions? The main hypothesis suggested here is that the site development took place during the Middle Chalcolithic and Late Chalcolithic periods, somewhere between 4500 and 3700 / 3600 BC. The second question relates to the geographical regions that Yataq-Tepesi was in contact with through cultural relations and trade with other regions of northwestern Iran, especially with the region of Qaradagh and the Lake Urmia basin, as well as with the Southern Caucasus.
Shapes of the pottery vessels from the burial ground of the Late Bronze Age near the village of Peschanka in the Southern Transurals
Authors: Klimova A.D.
Published: September 2022

In this article, the first experience of applying methods of the historical-and-cultural approach to the analysis of the shapes of the pottery of the Alakul Culture is presented. Eighteen vessels from 13 burials of the Peschanka cemetery were used. The aim of this work is to demonstrate the capabilities of the historico-cultural approach in the study of pottery vessel shapes of the Alakul Culture with the example of the burial ground of the Late Bronze Age in the Southern Transurals. The analysis has been carried out within the framework of the historical-and-cultural approach developed by A.A. Bobrinsky. The study of the vessel shapes is conducted at three levels of the analysis: (i) general proportionality of the vessels; (ii) natural structure of the vessel shapes; (iii) the degree of formedness of the functional parts of the vessels. The author has identified the features that characterize the leading trends in the traditions of creating forms of clay vessels in the studied population. At the level of general proportionality, the vessels are evenly distributed among stages 33–35. At the level of the natural structure, a five-part construction ‘lip + neck + brachium + body + base’ dominates. At the degree of formedness of the functional parts, most vessels exhibit a rudimentary neck, an unformed brachium, and the fully formed body. The listed features of the forms characterize the cultural core of the traditions of molding forms of the clay vessels at the Peschanka burial ground. The traditions of the cultural core are indicative of an early phase of the existence of this cemetery. Shapes of the vessels which differ from the core in their structures and degree of formedness of the body are representative of the later phase of the site's existence. This is confirmed by the traits of independent cultural and chronological features of the morphology of the Alakul and Srubnaya-Alakul ceramics, as well as by two available radiocarbon dates. The results of the conducted research showed the possibility of: a) deriving a cultural core of the traditions, with the example of the specific site; and b) establishing a chronology of burial complexes on the basis of data on the traditions of creating the vessel shapes.
Lead bullets of the Russian warrior host of 1582–1585 (based on the materials from the settle-ment of Isker)
Authors: Adamov А.А.
Published: September 2022

The capital of the Siberian Khanate, the Isker hillfort, is located on the right bank of the Irtysh River, 17 km up from the mouth of the Tobol River. A large collection of bullets has been assembled on the monument, which were left by the soldiers who participated in the Yermak's campaign. For the first time, the data on 30 bullets from Isker were reviewed by A.P. Zykov in a joint monograph published in 2017, which included the bullets stored in Tobolsk Museum Reserve. However, some conclusions made by the researcher were not supported by the mu-seum's collections. In total, 23 bullets are stored in the museum, and there are no bullets less than 8 mm in di-ameter, no bullets with a lead funnel, and no cylindrical bullets produced by cutting a lead rod into pieces. In total, our work made use of the data on 139 bullets that are stored in Tobolsk Museum Reserve and bullets that we found during the field research and collection of artefactual remains from the Isker hillfort since 2007. The bullets can be divided into two groups: molded (137 items) and mechanically manufactured (2 items). For the bullets, 12 variants of the traits, which characterize some features of their manufacture, and traces of impact on the projec-tiles before expulsion and those that appeared afterwards, were identified. During the manufacture, the bullet shape was attempted to be made spherical; this was recorded for 37.4 % of the items. Twenty-three percent of the bullets feature a seam from the mold sections, 14.4 % of the bullets preserved areas from lead shrinkage when cooling in the mold, 1.4 % of the bullets preserved a lead funnel, and 27.3 % of the bullets have notches made to increase their lethality. Furthermore, 58.3 % of the bullets bear traces of shooting — striation caused by friction of the projectile against the smooth barrel and traces of deformation caused by hitting a hard surface; only 10.1 % of the bullets are significantly undermolded or cut in halves. Summarizing the data on the bullets from the Isker hillfort, it must be noted that the Russian warrior host of 1582–1585 were armed with Russian-made muskets of small calibers of 8–15 mm. At the same time, the vast majority of them had a caliber of 10–14 mm, of which almost 2/3 were of a 12–13 mm caliber. The warriors campaigning in Siberia did not feel a noticeable shortage of ammunition, conducting annual target practice shooting at hard targets. Ball bullets were used, without lead funnels, which were cast from a precisely meas-ured amount of lead. Notched bullets were quite widely used.

Published: September 2022

Purpose – In an uncertain economic condition, maintaining companies’ profitability is essential. This study aims to analyze and assess the factors that affect bank profitability by focusing on internal factors such as capital, size, asset quality, and liquidity risk. This study also observed the effect of Islamic and conventional banking in Indonesia with a comprehensive profitability analysis as measured by ROA, ROE, and NIM/NOM.Methodology – The method used in this research was panel data regression. The data studied were derived from the quarterly reports of Islamic and conventional banking in Indonesia for five years, from 2016 to 2020.Findings – The results showed that conventional banking in Indonesia had a higher level of profitability than Islamic banking. The profitability of conventional banks is significantly influenced by the level of equity, size, CKPN, and LDR. On the other hand, Islamic banking in Indonesia generally has a lower level of profitability, but in terms of individual performance, the value was not inferior to conventional banking. Variables that significantly influence the profitability of Islamic banking included equity, CKPN, and FDR.Implication – Banks in Indonesia must improve their performance so that the development of asset size can be in line with the level of profitability generated, maintain asset quality so that the health of the bank is maintained, and has proportional equity and LDR/FDR value.Originality – This research used three profitability ratios: ROA, ROE, and NIM/NOM, and analyzed Islamic and conventional banking, considering that Indonesia has a dual banking system, so the analysis carried out was more comprehensive.

Published: September 2022

Tuberculosis is the 13th trigger of death causes around the world. Even after Covid-19, tuberculosis ranks 2nd as a contagious killer disease. In 2020, Indonesia ranks 2nd out of 8 countries with the highest contributor to tuberculosis sufferers after India. East Java Province is the region with the largest number of tuberculosis cases in order of 8. Tuberculosis cases in East Java in 2020 have decreased, but when viewed from the success rate of treatment of tuberculosis cases per district/city in East Java, it was found that 53% still did not meet the target of 90%. According to (World Health Organization), gender affects the occurrence of tuberculosis disease, where men are more susceptible than women. In finding treatment for all tuberculosis incidents in East Java, the highest patient was male. This study was conducted to model tuberculosis in men in the East Java area. The results of the study prove that the modeling of male tuberculosis in East Java used linear regression and GWR  (Geographically Weighted Regression) obtained the best model was GWR with Fixed Gaussian Kernel weighting, CV value of 5.68, and R2 86.47%. Variables that have a significant effect on male tuberculosis in East Java are BCG immunization for male infants, public places meeting health requirements, youth who smoke tobacco every day, sex ratio, and households with access to proper sanitation facilities.

Published: September 2022

Intervention analysis is a method for processing time series data that can be used to explain the effect of an intervention that is influenced by external and internal factors. One application of this method is the data on the number of foreign tourist visits. Since the emergence of COVID-19 in Indonesia, especially in March 2020, Indonesia has begun to implement a lockdown policy and restrict foreign tourists from entering Indonesia. Lockdown policy caused the number of foreign tourist arrivals to decreased drastically. The purpose of this study was obtained a model and forecast results for the number of foreign tourist arrivals for the period November 2021 to November 2022 used a step function intervention analysis. The results of the analysis was shown that the ARIMA intervention model (0,1,1) with a step function with an intervention orde of b=0, s=0, and r=0 was the best model. The results of forecasting the number of foreign tourist visits to Indonesia will increase slowly from November 2021 to November 2022 with a MAPE value 9.91%.

Authors: Sintia Ineu , Suyitno Suyitno , Hayati Memi Nor
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.

Properties and detectability of rogue synthetic biology (SynBio) products in complex matrices
Authors: Jung Carina , Indest Karl , Carr Matthew , Lance Richard , Carrigee Lyndsay , Clark Kayla
Published: September 2022

Synthetic biology (SynBio) aims to rationally engineer or modify traits of an organism or integrate the behaviors of multiple organisms into a singular functional organism through advanced genetic engineering techniques. One objective of this research was to determine the environmental persistence of engineered DNA in the environment. To accomplish this goal, the environmental persistence of legacy engineered DNA building blocks were targeted that laid the foundation for SynBio product development and application giving rise to “post-use products.” These building blocks include genetic constructs such as cloning and expression vectors, promoter/terminator elements, selectable markers, reporter genes, and multi-cloning sites. Shotgun sequencing of total DNA from water samples of pristine sites was performed and resultant sequence data mined for frequency of legacy recombinant DNA signatures. Another objective was to understand the fate of a standardized contemporary synthetic genetic construct (SC) in the context of various chassis systems/genetic configurations representing different degrees of “genetic bioavailability” to the environmental landscape. These studies were carried out using microcosms representing different environmental matrices (soils, waters, wastewater treatment plant (WWTP) liquor) and employed a novel genetic reporter system based on volatile organic compounds (VOC) detection to assess proliferation and persistence of the SC in the matrix over time.
Stability analysis of Old River Low Sill Structure
Authors: Walshire Lucas , Dunbar Joseph , Breland Benjamin
Published: September 2022

An updated stability analysis was performed on the Old River Low Sill Structure due to a change in the operating conditions from historic river sedimentation. Sedimentation of the Mississippi River channel since the 1973 spring flood has caused higher river stages at lower discharges. Numerical methods used included nonlinear analysis of pile group stability, seepage analyses, and limit equilibrium methods. The structure’s foundation was compromised during the 1973 flood, and emergency repairs were conducted to prevent scouring and undermining of the foundation by the flood scour. Rehabilitation included the reconstruction of a failed wing wall on the left abutment, rock and riprap fill in the forebay channel, and emergency grouting to fill the scour hole beneath the structure. An operating restriction was emplaced to limit the differential head across the structure due to flood damage. Taking these conditions into account, results from an updated analysis showed that full headwater uplift caused increased tension in the piles, while the increased body load caused increased compressive loads in the piles. Review of piezometric monitoring and the seepage analyses showed that full headwater uplift is unlikely, indicating the foundation grouting adequately sealed the scour hole beneath the structure. Analysis results exhibited lower magnitude compression and tension loads in the piles with design load cases compared to previous analyses. Recommendations from these analyses indicate that increased monitoring and additional investigation may support increasing the differential head limitation.
Evaluation of 11 buildings in the Fort McCoy cantonment
Authors: Adams Sunny , Story Madison , Smith Adam
Published: September 2022

The United States Congress codified the National Historic Preservation Act of 1966 (NHPA), the nation’s most effective cultural resources legislation to date, mostly through establishing the National Register of Historic Places (NRHP). The NHPA requires federal agencies to address their cultural resources, which are defined as any prehistoric or historic district, site, building, structure, or object. Section 110 of the NHPA requires federal agencies to inventory and evaluate their cultural resources, and Section 106 requires them to determine the effect of federal undertakings on those potentially eligible for the NRHP. Fort McCoy is in west-central Wisconsin, entirely within Monroe County. It was first established as the Sparta Maneuver Tract in 1909. The post was renamed Camp McCoy in 1926. Since 1974, it has been known as Fort McCoy. This report provides historic context and determinations of eligibility for buildings in the cantonment constructed between 1946 and 1975 and concludes that none are eligible for the NRHP. In consultation with the Wisconsin State Historic Preservation Officer (WISHPO), this work fulfills Section 110 requirements for these buildings.
Methane Diffusion Through Nanopore-Throat Geometry: A Molecular Dynamics Simulation Study
Authors: Sun Runxuan , Xu Ke , Huang Tianjia , Zhang Dongxiao
Published: September 2022

Molecular diffusion dominates over pressure-driven convection as the major mass transport mechanism in nanoporous media with <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
Authors: Kudryavtseva O. V. , Serebrennikov E. V.
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.

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.

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.

Published: September 2022

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.

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.

Environmental 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).
