Deteriorating Women's Health Due to Rising Exposure to Per and Polyfluoroalkyl Substances (PFAS): A Review
Authors: Sand Tangri , Kumari R.
Published: January 2024

A major class of water pollutants emerging as a threat to human health, particularly women's health, is Per-and-poly-fluoroalkyl substances (PFAS). PFAS belongs to a group of fluorine-containing frequently used synthetic chemicals in consumers and products manufactured by industries. The major concern linked to PFAS is that they exhibit bioaccumulation potential as their perfluorocarbon moieties do not degrade or degrade extremely slowly when exposed to natural elements. The reason PFAS has been termed "forever chemicals." These chemicals are disposed of in aquatic bodies via improper disposal methods, PFAS also build or concentrate in the aquatic environment because they are persistent. These chemicals further enter the human food chain via drinking water. Consumption of PFAS by women leads to catastrophic health effects such as disruption of reproductive functions, development of fetal irregularities in pregnancy, alteration of hormone secretions, menstrual cyclicity irregularities, etc. They have even been linked to life-threatening diseases, such as the development of cancer in women. In this study, we have reviewed the existing research works available to understand the alarming consequences of PFAS on female health and the various challenges being faced due to inadequate treatment and management of these chemicals. Further, the scope of developing mathematical models for studying the extent of the harmful effects of PFAS on women's health as well as devising proper management and disposal practices, is discussed in this paper.

In the modern era, there are numerous ways for drug delivery. The change in time has led to the progress of drug delivery systems gaining significant development. Even though most of the drugs are administered orally i.e., in conventional dosage form it has its limitations too like poor patient compliance, metabolism in the liver's first passage, poor absorption, and fluctuations in plasma level.Because our skin is indeed the largest organ, transdermal medication administration has received increased attention in recent years. Many lipids nanovesicles like Liposomes, Niosome, Ethosome, and Transfersomes have been developed as a carrier for transdermal drug delivery. But out of them, Transfersomes are the ones which are of great interest as they show better permeation among all as most of the other carriers cannot pass through the stratum corneum. The method of transdermal medication administration has been used to provide controlled and targeted action and can act as topical and dermal preparation. This review provides basic information about Transfersomes, their mechanism of action, applications, and comparison with other lipid nanocarriers.

Published: January 2024

In this paper, we report on extensive experiments conducted to evaluate Internet of Things (IoT) sensor performance in monitoring urban air quality. As certified sensors showed a considerably reduced air quality measurement error of 4.3% compared to uncalibrated sensors at 8.5%, our results highlight the crucial function of sensor calibration. The performance of sensors was impacted by environmental factors; higher temperatures produced better accuracy (3.6%), while high humidity levels caused sensors to react more quickly (2.3 seconds). The average air quality index (AQI) recorded by inside sensors was 45, but outside sensors reported an AQI of 60. This indicates that the positioning of the sensors had a substantial influence on the air quality data. Additionally, the methods of data transmission were examined, and it was found that Wi-Fi-transmitting sensors had lower latency (0.6 seconds) and data loss (1.8%) than cellular-transmitting sensors. These results emphasize the significance of environmental factors, sensor placement strategy, sensor calibration, and suitable data transmission techniques in maximizing IoT sensor performance for urban air quality monitoring, ultimately leading to more accurate and dependable air quality assessment.

Published: January 2024

This study analyzes the sea currents, temperature, and salinity in the Malacca Strait during the northeast (NE) and southwest (SW) monsoons of 2022, represented by monthly average data from the Copernicus Marine Service (CMEMS) data portal for January and July, respectively. Vertical sections are created to visualize the layer structure and variations of sea parameters within the water column. The findings reveal differences in sea currents, temperature, and salinity between the NE and SW monsoons. July (SW monsoon) records consistently warmer temperatures than January (NE monsoon), both at the sea surface and seabed. Surface salinity is higher in July than in January, while seabed salinity is greater in January than in July. In January, the salinity-influenced mixed layer depth (MLD) appears to be thicker than the temperature-influenced MLD. There are no significant differences in the thickness of the temperature- and salinity-influenced MLDs during July. These variations in sea currents, temperature, and salinity at different depths provide a comprehensive understanding of the marine environmental structure and dynamics of the Malacca Strait.

Transformers play a pivotal role in the distribution of electrical energy, particularly in electronic devices. Load resistance significantly influences transformer efficiency. This study employs an experimental methodology with the objective of assessing the congruence between experimental data analysis and theoretical calculations. The experimental setup involves testing a step-up transformer characterized by the following primary coil specifications: Np (number of turns) = 500, rp (resistance) = 2.5 Ω, Lp (self-inductance) = 9 mH, and secondary coil specifications: Ns (number of turns) = 1000, rs (resistance) = 9.5 Ω, Ls (self-inductance) = 36 mH. Load resistance (R) is varied within the range of 10 to 500 Ω. The outcomes reveal a progressive enhancement in transformer efficiency with the increasing load, up to 300 Ω, after which efficiency experiences a decline. In the case of a step-down transformer, possessing identical specifications as the step-up variant, efficiency displays an analogous pattern of augmentation with load resistance up to 80 Ω, beyond which it diminishes. Furthermore, the Root Mean Square Error (RMSE) for the step-up transformer stands at 0.0012, with an R-square (R2) value of 0.99. Similarly, for the step-down transformer, RMSE registers at 0.0060, accompanied by an R-square (R2) of 0.99. These findings affirm the exceptional adequacy of the employed theory in elucidating the intricate interplay between transformer efficiency and load resistance.

Published: January 2024

The era of technology has opened space to facilitate daily tasks. Security cameras have nowadays become a necessity for every expert’s safety environment. A buzzer, PIR sensor, PI camera, and Raspberry Pi are used to create home security systems. The PIR sensor detects motion, the PI camera snaps an image, and the buzzer beeps. A notification will be delivered immediately to the owner’s Telegram account when the camera captures the person’s face and enables the posting of live video of that moment. It enables the user to record the incidents that happen at home. The purpose of developing the Telegram application is mainly to provide the owner with an Android application because nowadays society is more dependent on mobile technology. PIR sensors will be active when they detect people or animals, but they will deactivate when they detect breezes. As a result, the PI Camera will only record images of things like people and animals, not the wind. The PIR sensor, PI camera, and buzzer will all have a linear relationship to one another. When the PIR sensor is turned on, the PI camera and buzzer will also turn on, and vice versa.

Published: January 2024

This research seeks to investigate how corporate social responsibility (CSR) and environmental performance impact the financial profitability of a company. The approach employed is a quantitative methodology utilizing cross-sectional regression analysis with a sample comprising 72 manufacturing companies listed on the Indonesia Stock Exchange (IDX). The study findings reveal that the impact of CSR (
b=0,11;p-value=0,07) on financial performance is inconclusive. This is due to companies being unable to validate that their social responsibility aligns with community expectations, indicating no clear effect of CSR and environmental performance on company profitability.. On the other hand, environmental performance(
b=0,07;p-value=0,00) affects the profitability of the company. This condition can be achieved because within the framework of legitimacy theory, the public considers that industrial waste processing carried out by the companies that are the sample in this study has a good impact on the company’s environment, which in turn will increase competitive advantage and ultimately increase company profits.

Published: January 2024

The paper considers one of the unique fields in terms of geological reserves. The paper also analyzes the development of the D3ps formation sections of the Devonian terrigenous layer of the studied field. A detailed geological and hydrodynamic model was constructed based on the consolidation of all available information. An integrated analysis of actual well performance data, field geophysical tests, geological and technical measures, results of infill drilling, as well as geological and hydrodynamic modeling confirmed the localization of reserves primarily in the upper bed of D3ps.1. The analysis of all performed studies revealed higher values of current oil saturation in the upper bed – up to 0.8 unit fractions and lower values in the lower bed – up to 0.68 unit fractions. Similar results were obtained from 87 sidetracks. Drilling of wells and sidetracks is proposed in areas with no well stock. Despite the final stage and high degree of field development, the proposed strategy will support oil production levels, increase remaining recoverable reserves, increase the efficiency of reserve recovery and improve the economic performance of field development. The introduction of modern development technologies, approaches to the analysis and monitoring of development will increase the target value of the final recovery factor from 0.608 to 0.613 unit fractions, which, with a significant amount of in-place reserves, made it possible to increase the remaining recoverable reserves by 35%. The strategy will make it possible to achieve higher oil recovery rates. The approaches used to solve the tasks set in the study can be applied to the fields of the Volga region.
Analysis of the effect of anthropogenic load the vital forest condition Arctic zone of the Russian Federation
Authors: Surina E.A. , Yakovenko N.V.
Published: January 2024

The influence of anthropogenic factors on the state of forest stands is manifested mainly in the Arkhangelsk region, in the Murmansk region and in the Krasnoyarsk territory. It has been established that the action of anthropogenic factors in the forests of the Arkhangelsk region was not the primary cause of the weakening of the forest stand. At the same time, an extremely insignificant degree of damage was noted, in comparison with other causes of weakening and death of plantings. The reason for the death of the vast majority of forests in the region as a result of the anthropogenic factor was a violation of the rules of tapping, when ripe and overmature pine forests, after use, were not cut down and are now a potential source of occurrence and spread of foci of diseases and forest pests. When drying out, not only the likelihood of developing large forest fires increases, but also mass reproduction of forest pests occurs. First of all, arrays of old (age 150-250 years) trees are affected, which were not cut down in a timely manner due to the inaccessibility for industrial harvesting and removal of commercial timber. Therefore, forest protection measures need to be given more attention. It is possible to preserve and increase forest wealth only through sustainable forest management, preserving biological diversity, productivity, the ability to restore, viability and the ability to perform important ecological, economic and social functions at the local, national and global levels in the present and future

Irrigation is a method of applying water to land or soil to assists the growth of crops. Moisture loss is a common problem in the agricultural situation in developing countries. Therefore, a study was conducted to set up a controlling system for irrigation that is based on the moisture content of soil of the crop field to prevent water and electrical waste using a singlephase water pump and to test the performance of the machine at the field level. The irrigation control machine functions with the help of two electrodes used to measure the soil water content were developed successfully using the low-cost electrical and electronic accessories which functions with DC voltage. This study highlights that the automatic machine was successfully performed in the field. When the machine was used in the field, the vegetative parameters such as average plant height and mean leaf area of the maize plants which was grown under the irrigation of an automatic irrigation system were significantly greater than the normally irrigated plants. Further, the maize plants grown under the automatic irrigation system showed early flowering and 34% average individual plant yield improvement compared to the conventional irrigation system.

For the first time, data were obtained on the use of the cyanobacteria Arthrospira platensis endometabolite complex and its modifications, fortified (additionally enriched) with nutrients B, Se, and P in soybean cultivation technology, which acted not only as growth regulators, but also as adaptogens to external abiotic stress factors during the growing season of the studied crop. It was found that the use of complexes fortified with phosphorus and selenium in pre-sowing seed treatment (0.6 l/t) and foliar top dressing of vegetative soybean plants in the phase of 1-3 triple leaves provides the greatest increase in grain yield by 0.23 and 0.2 t/ha, or by 10.1 and 8.8% in the indeterminate Mezenka variety, and protein collection at the same time is 1022.5 and 1012.7 kg/ha, respectively.

The work is aimed at assessing the potential of using the yeast culture Wickerhamomyces anomalus CBS605T in bread baking. The in vitro antimicrobial activity of the yeast culture Wickerhamomyces anomalus (CBS605T) against the causative agent of potato disease, Bacillus subtilis, was studied. A rheoenzymemetric assessment of the gas-forming and gas-retaining abilities of the studied strain during fermentation in wheat dough was carried out. The study showed that the yeast culture Wickerhamomyces anomalus (CBS605T) effectively inhibits the growth of Bacillus subtilis and has higher fermentation activity than the control organism Saccharomyces cerevisiae var. boulardii (Y3925), also known for antimicrobial activity against the pathogen of potato disease.

Published: January 2024

The CME review presented here is intended to explain the significance of pleural sonography to the interested reader and to provide information on its application. At the beginning of sonography in the 80 s of the 20th centuries, with the possible resolution of the devices at that time, the pleura could only be perceived as a white line. Due to the high impedance differences, the pleura can be delineated particularly well. With the increasing high-resolution devices of more than 10 MHz, even a normal pleura with a thickness of 0.2 mm can be assessed. This article explains the special features of the examination technique with knowledge of the pre-test probability and describes the indications for pleural sonography. Pleural sonography has a high value in emergency and intensive care medicine, preclinical, outpatient and inpatient, in the general practitioner as well as in the specialist practice of pneumologists. The special features in childhood (pediatrics) as well as in geriatrics are presented. The recognition of a pneumothorax even in difficult situations as well as the assessment of pleural effusion are explained. With the high-resolution technology, both the pleura itself and small subpleural consolidations can be assessed and used diagnostically. Both the direct and indirect sonographic signs and accompanying symptoms are described, and the concrete clinical significance of sonography is presented. The significance and criteria of conventional brightness-encoded B-scan, colour Doppler sonography (CDS) with or without spectral analysis of the Doppler signal (SDS) and contrast medium ultrasound (CEUS) are outlined. Elastography and ultrasound-guided interventions are also mentioned. A related further paper deals with the diseases of the lung parenchyma and another paper with the diseases of the thoracic wall, diaphragm and mediastinum.

Computable general equilibrium analysis of neutral carbon trading scheme and revenue recycling impacts on income distribution in China
Authors: Qi Lingli , Zhao Lei , Zhang Yongqiang , Jiang Shiqi , Lin Xinyue , Ren Yishuai
Published: January 2024

Utilizing a dynamic computable general equilibrium (CGE) model, this paper critically assesses the potential distortions and efficacy of various revenue-neutral carbon emission trading schemes (ETSs) in China, through government subsidies and value-added tax (VAT) relief strategies aimed at achieving peak carbon emissions before 2030. The analysis reveals that reallocating market revenues to the production sector, either through government subsidies or VAT reductions, can feasibly attain carbon peaking before 2030, with minimal impact on GDP. Notably, both government subsidies and VAT cuts foster output growth in the oil, gas, and ETS-covered sectors. Moreover, directing carbon market revenue toward ETS-covered industries via VAT relief emerges as the most effective approach to reducing income disparities. In contrast, redistributing carbon market revenue to non-ETS-covered industries via VAT relief is found to be the least effective in promoting social equity. The study emphasizes that the reallocation of carbon market revenues to ETS-covered sectors is paramount. This strategy not only regulates the overall energy consumption effectively but also steers the nation towards a more sustainable and optimized energy consumption pattern. In light of these findings, this paper offers detailed insights and tailored policy recommendations, aiming to assist policymakers in striking a balance between environmental goals and economic and social imperatives.

Published: January 2024

We prove sharp estimates on the time-average behavior of the squared absolute value of the Fourier transform of some absolutely continuous measures that may have power-law singularities, in the sense that their Radon–Nikodym derivatives diverge with a power-law order. We also discuss an application to spectral measures of finite-rank perturbations of the discrete Laplacian.
