In recent decades, metal-containing nanocomposites have attracted considerable attention from researchers. In this work, for the first time, a detailed analysis of the preparation of reactive indicator papers (RIPs) based on silver-containing nanocomposites derived from silver fumarate was carried out. Thermolysis products are silver-containing nanocomposites containing silver nanoparticles uniformly distributed in a stabilizing carbon matrix. The study of the optical properties of silver-containing nanocomposites made it possible to outline the prospects for their application in chemical analysis. RIPs were made by impregnating a cellulose carrier with synthesized silver fumarate-derived nanocomposites, which change their color when interacting with chlorine vapor. This made it possible to propose a method for the determination of chloride ions with preliminary oxidation to molecular chlorine, which is then separated from the solution by gas extraction. The subsequent detection of the active zone of RIPs using colorimetry makes it possible to identify mathematical dependences of color coordinates on the concentration of chloride ions. The red (R) color coordinate in the RGB (red-green-blue) system was chosen as the most sensitive and promising analytical signal. Calibration plots of exponential and linear form and their equations are presented. The limit of detection is 0.036 mg/L, the limits of quantification are 0.15–2.4 mg/L, and the time of a single determination is 25 min. The prospects of the developed technique have been successfully shown in the example of the analysis of the natural waters of the Don River, pharmaceuticals, and food products.

In the past decade, the Chinese paper industry, which is highly polluting and energy intensive, has shown overall increases in production, sales, income, and profit, although the growth rate has declined. Overall, China’s paper industry exhibits small-scale and scattered distribution, characterized by continuous overcapacity and outdated technical knowledge. This has inevitably resulted in a variety of serious environmental problems during its development. Owing to the environmental problems resulting from the development of the paper industry, various environmental regulatory policies and measures have been adopted in China, mainly command-and-control, market-based, and voluntary policies and measures. This study identifies and analyzes particular issues inherent to China’s environmental regulatory policies and measures regarding the paper industry and proposed policy suggestions for improving the environmental regulation of China’s paper industry.

Paper has been increasingly used in recent years as a substrate in the structure of sensors to determine diverse biological and pharmaceutical molecules and ions. Potentiometric sensors built with paper offer certain improvements since they are cost–effective, portable, biodegradable, eco–friendly, disposable and easy to manufacture. Paper is also an ideal substrate to be used, considering that it is flexible, lightweight, mechanically–resistant, a good medium for immobilization and trapping, and that it can be easily chemically and physically modified for customized applications, it can adsorb and transport liquid via capillary forces, can close the electrical circuit between electrodes when wet, it can be produced in diverse geometrical dimensions and porosities. Due to these characteristics, paper–based potentiometric sensors are more eco–friendly, suitable to be used in resource–limited areas, can be used in remote locations or on–site settings with low–cost analytical instrumentation. To our knowledge, the most recent advancements in the field have not been collectively reviewed, and this is of high importance considering the rapid developments made in paper–based potentiometric sensors lately. In these review, we covered paper–based potentiometric devices developed in the very recent years, detailed their structures, and compared their certain performance parameters including detection limit, linear concentration range, response time and applicability.

This research employs critical discourse analysis (CDA) to examine a news article titled "KPU Chief Rebuffs Allegations of Bias during VP Debate" from the Jakarta Post, focusing on the transition from print to online media or E-Paper. In this research, the two main methods used to collect data are documentation via the Jakarta Post e-paper news page and content review. This approach provides the advantage of exploring information in depth and comprehensively related to the phenomenon or event that is the focus of the research. Utilizing Teun A. van Dijk's CDA framework, the analysis encompasses macro, superstructure, and micro structures. The macro-structural analysis reveals the social and political context, identifying social groups and emphasizing narrative importance. The critical discourse superstructure analysis delves into linguistic patterns, representations of power, and strategic language use. Finally, the micro-structural analysis explores word choice, grammar, writing style, and sentence structure to understand how language constructs arguments and responds to accusations. Through these lenses, the study provides a comprehensive understanding of how the news shapes and reflects social and political dynamics, contributing valuable insights into media discourse surrounding political events in Indonesia.

Abstract To reduce pollution emissions and achieve a cleaner production in paper industry, it is essential to understand the inner links between concentrations of gaseous pollutants, types of final products and production techniques. In this study, the concentrations of four potential gaseous pollutants, total volatile organic compounds (TVOC), formaldehyde (HCHO), hydrogen sulfide (H 2 S), and hydrocarbon compounds (C x H y), in the ambient air on thirty sampling points of five pulp and paper mills were detected and analyzed. The results were summarized with respect to the following aspects: (1) Levels of four gaseous pollutants on all the sampling points in five mills. It was obvious that the situation of gaseous pollution from pulp mill was much more serious than those from paper mills. (2) Gaseous pollutant distinctions due to different production processes. The levels of gaseous pollutants from five mills were greatly influenced by the utilized raw materials and the applied paper chemical agents (flavor, coating materials and additives) in mills. (3) Gaseous pollution comparisons at common points. At the two common points in five mills, i.e. the wet end of paper machine and the wastewater treatment process, TVOC and HCHO, C x H y and H 2 S were the main gaseous pollutants, respectively. In addition, some feasible measures to realize a cleaner production in pulping and papermaking process were also put forward in the article. Highlights • We analyze the levels of 4 gaseous pollutants on 30 sites of 5 pulp & paper mills. • Gaseous pollution distinctions due to different production processes are studied. • Feasible measures to realize the cleaner production in the processes are suggested. • Gaseous pollution are greatly affected by raw materials and added paper chemicals.

Alkyl ketene dimer (AKD) is the reactive synthetic sizing agent that is used in alkaline or neutral papermaking conditions to provide certain level of hydrophobicity to the paper and board. The sizing mechanism of AKD involves its reaction with the hydroxyl groups on cellulose. However, all of AKD does not chemically react with fibers; some of it may undergo hydrolysis in water to form unstable β-keto acids, which decarboxylate to the corresponding ketone. This portion of AKD remains non-reacted (unbound) and adsorbs onto fibers. The sizing effect depends mainly on the quantity of chemically reacted (bound) AKD in paper, while the role of unbound forms, that is ketone and oligomer, is still not clear. Both bound and unbound portions of AKD have their own effect on paper. It is important to know the proportion of bound and unbound form of AKD in paper. The different techniques have been adopted for the separation and analysis of bound and unbound AKD present in paper. The aim of this paper is to review and summarize the various techniques provided by the researchers to separate the different forms of AKD and highlight the most important aspects for their separation.

This paper explains recent findings that the paper-bill spread helps forecast consumption spending using an intertemporal optimizing model of consumption and portfolio allocation. The spread is simply the opportunity cost in terms of foregone future consumption of homing government debt rather than higher yielding private debt. Thus, if government debt appears along with consumption in the single period utility function, the spread appears in one of the Euler equations for consumption and asset accumulation. Empirical tests strongly support the model. Finally, including the spread in a rule of thumb model of consumption reduces the importance of non-optimizing behavior. (JEL E21, E43, C22, C32), I. INTRODUCTION One of the more interesting recent findings in empirical macroeconomics is that the paper-bill spread, the difference between the yields on six month prime commercial paper and six [...]

The digitalization era of public relations is increasingly affecting the means of presenting information about the economic activities of an enterprise, in particular financial, in the context of a global pandemic, which was caused by the global COVID-19. Increasingly, in our environment, there is a transition from paper to electronic information carriers. The financial information generated by business entities both in Ukraine and in the world as a whole is no exception. The purpose of the study is to systematize the existing digital formats for presenting financial information as a basis for analyzing and auditing the business activities of enterprises in Ukraine. The basis of the study is the methodological recommendations on the use of Taxonomy UA XBRL IFRS, instructions for the revision of the Ukrainian IFRS taxonomy, specialized software products, legislative framework of Ukraine. The following methods were used: graphical (to visualize the results of the study), and grouping (to systematize the advantages and disadvantages of software that uses tax services to conduct e-audits). Digital formats for the presentation of financial information were analyzed. They are the basis for the analysis and audit of the enterprise's activities. The structure and characteristics of the legal framework for the disclosure of financial information in electronic XBRL format in Ukraine were given. Comparative analysis of financial information in digital format XBRL and SAF-T UA were carried out. It has been determined that XBRL can be used as a basis for analyzing financial information in electronic format using special software, for example, to assess the financial condition, calculate indicators of financial stability, liquidity, solvency, business activity, enterprise profitability, etc. It has been proved that the electronic format of financial information SAF-T UA is used when conducting an electronic audit (e-audit) of taxpayers, and can also be used to calculate the tax burden (tax return, tax efficiency ratio) used by the State Tax Service of Ukraine for the purpose of control completeness of calculation and payment of relevant taxes and fees to the state budget.

This study focused on the behavior of the paper-polypropylene-paper (PPP) laminate while aging in hot oil in the absence of voltage stress. The results provide an understanding of both the quality of the interfacial bond and the performance of this bond during service. X-ray photoelectron spectroscopy performed on two different peeled laminates suggest that the bond failed primarily adhesively. Weibull statistical analysis of the peel strength data obtained on unaged laminates and those aged in polybutene oil at 90 ° C for 120 hours showed that the strength loss is consistent with one failure mechanism and the failure rate increases with applied stress. For the aged sample, Weibull analysis results are consistent with the prior loss of peel strength due to the aging. Experiments on the solubility of the oil show that lamination reduces the amount of absorption in comparison to the unlaminated composite. Swelling experiments on the individual components show differential swelling between the paper and polypropylene to be the source of the strength loss. The polypropylene swells, and the paper shrinks. Measurements on the laminate show that both paper and polypropylene shrink, indicating that the paper governs the laminate swelling process. During aging, the differential swelling generates internal stresses on the interface. In addition to yielding the magnitudes of these stresses, finite element analysis also predicts plastic deformation and creeping of the polypropylene as well as tensile stresses between the paper and polypropylene at a free edge. Very likely these processes damage the bond and contribute to the loss of bond strength., INTRODUCTION The PPP laminate has been shown to be an acceptable insulation for the high pressure oil-filled high voltage power cable on the basis of dielectric properties and economic feasibility.
