The recovery rate of paper products is a key factor in measuring the recyscling potential and the sustainability of the paper industry. Accurately measuring the recovery rate of paper products holds important theoretical and practical value. This paper took the non-recycling part and time factor into account and built the Koyck model to estimate the recovery rate, storage loss rate and recovery cycle of paper products. The model results showed that the recovery rate of Chinese paper products in 2017 increased to 58.05%, which was 10% higher than the results of methods that did not contain the non-recycling part or the time factor. The model results also showed that the storage loss rate of Chinese paper products was much higher than that of developed countries while the recovery cycle was close to the level of developed countries. The distribution analysis showed that the storage loss rate and recovery cycle of Chinese paper products varied significantly over time, which may be the result of policies and the change of consumption structure. It is suggested that the Chinese government should take measures to reduce the storage loss rate of paper products and enhance their recycling ability to achieve sustainable development.

The papers of Beck and Snider (this issue) grapple with the place of abortion in our psychoanalytic thought and practice, locating abortion within the larger cultural and political world. At the heart of much of the difficulty surrounding a thoughtful consideration of abortion is the accompanying dissociative pressure arising from the binaries of life and death, of maternal versus fetal well-being, and the confounding of socio-cultural and personal decision making. I offer an intergenerational lens juxtaposing the polarized present with the open and accessible abortion landscape of the late 1970s. In both eras, examples are discussed where the political and cultural zeitgeist exerts dissociative pressure on patient and therapist alike, leaving little room for psychoanalytic exploration. The role of both partners in any conception is also discussed. [ABSTRACT FROM AUTHOR]

This study seeks to profile the shoppers' propensity to reuse shopping bags and the type of shopping bags they reuse on the basis of demographics. The study used an observation method to record the consumers' shopping habits and a short questionnaire to record the participants' demographics. A binary regression analysis and a multinomial regression analysis were used to analyse data. The results indicated that the mature aged, women, and low income shoppers were more likely to practice reuse of plastic shopping bags than their respective counterparts. There were no statistically significant differences in the likelihood of young aged shoppers compared to mature aged shoppers and low income shoppers compared to high income shoppers using cotton bags than plastic bags. There were also no statistically significant differences in the likelihood of young aged shoppers compared to mature aged shoppers and male shoppers compared to female shoppers using paper bags than plastic bags. However, the results indicated a statically significant result in how males compared to females differed in their using of cotton bags than plastic bags and a statistically significant result in how low income shoppers compared to high income shoppers differed in their use of paper bags than plastic bags.

The aim of this study is to evaluate the performance of coagulation and flocculation (C/F) process and economic analysis for the advanced primary treatment in order to obtain a semi-closed water circuit in the pulp mills in the cardboard recycling industry. Since the high water quality level is not required in the pulpers, the dosages in this research were determined without pH changes or adjustment to decrease the capital and operational expenditures. The results showed that FeCl3 with the concentration of 2000 mg/L gave the best quality when coagulants were used solely. Moreover, using alum with the concentration of 1500 mg/L provided acceptable quality for the effluent re-circulation and the removal/reduction percentages of 42, 82, 71 and 97 were achieved for chemical oxygen demand (COD), total suspended solids (TSS), turbidity and colour, respectively. It was also found that the combination of coagulants did not improve the process performance significantly. The best combination was ferric chloride (500 mg/L) and alum (2000 mg/L) with the efficiency of 47% and 98% in terms of COD and colour removal/reduction, respectively, while the best couple in TSS removal was FeCl3 (500 mg/L) and CaCO3 (500 mg/L) with the efficiency of 88%. The chemicals coupled with cationic polyacrylamide (C-PAM) did not enhance the quality of pre-treated solutions when the settling time reduced up to 15 minutes. The cost analysis also showed that alum is the most cost-effective coagulant with the costs in the range of 0.06–0.12 $/kg removed TSS, 0.06 to 0.11 $/kg removed COD and 0.06–0.1 $/m3·reduced NTU whereas calcium carbonate is the economic coagulant regarding colour reduction with the cost of 0.003 $/m3·reduced unit and more than the reduction efficiency of 90%.

This article is a response to Amanda Kottler's paper on the concept of multiple self-states and the role of writing in understanding clinical moments. The author, Joye Weisel-Barth, discusses the symbolic presence of Isobel in Kottler's paper and how it represents a hidden self-state that brings about transformative experiences. Weisel-Barth also explores the use of fiction as a tool for self-discovery and emphasizes the importance of aesthetic engagement in uncovering hidden aspects of oneself. The article highlights the power of writing and imagination in gaining a deeper understanding of the self, and encourages readers to consider the broader implications of psychoanalysis in understanding the self and its connection to the surrounding environment.

This study aims to explore how e-textbooks with emotional design affect students' emotion, cognitive load and learning achievement. There were 147 freshman students in total: the experimental group I, II and control group consisted of 49, 47 and 51 students, using e-textbooks with emotional design, without emotional design and traditional paper textbooks. The results reveal the following: Students' emotion after using e-textbooks with emotional design is more positive than those using e-textbooks without emotional design and paper textbooks. Students' cognitive load after using e-textbooks with emotional design is significantly lower than those using etextbooks without emotional design. Students' learning achievement after using two types of e-textbooks is better than after using paper textbooks. Comparing all types of textbooks altogether, emotion has a significantly positive correlation with learning achievement, and both emotion and learnng achievement are significantly and negatively correlated with cognitive load. For the three types of textbooks, the relationship between emotion and learning achievement all becomes not significantly correlated. For two types of e-textbooks, cognitive load and learning achievement become not significantly correlated, disturbed by the digitalization of textbooks. Instructors are suggested to firstly adopt e-textbooks with emotional design, those without emotional design secondly, and paper textbooks rank last. [ABSTRACT FROM AUTHOR]

A descriptive annotated bibliography is presented of recent selected publications dealing with the reported health benefits and risks of fish and seafood consumption; fish and seafood including farmed and wild-caught finfish, crustaceans, mollusks, and seaweeds. The bibliography is presented in four parts, namely (1) review papers dealing with both the health benefits and risks of fish and seafood consumption, (2) specific papers dealing with health benefits related to: antioxidants; bone health; brain and mental health; cancer prevention; diabetes prevention; elderly and senior adults; fermentation; heart health and hypertension; immune response and allergies; infant and child health; lipids, fatty acids and sterols; minerals and trace elements; obesity and overweight reduction; polysaccharides; pregnancy and gestational health; proteins, peptides and amino acids; and vitamins and bioactive compounds; (3) specific papers dealing with health risks related to: algal blooms and shellfish biotoxins; antibiotics use and residues; cancer risks; chemicals; chronic kidney disease; microbial quality and safety; microplastics; minerals and heavy metals; parasites and pathogens; pesticides and persistent organic pollutants; public perception and media; seafood allergy; and smoking risks; and (4) supporting papers dealing with consumption advisories and dietary guidelines; improved decontamination and processing methods; and fish, food and nutrient security. A total of 552 papers are presented together with their annotated summaries. On the basis of the papers presented in this review, it is believed that the higher nutritional value and health benefits derived from increased fish and seafood consumption far out-way the potential negative risks to human health, and as such fish and seafood represent a valuable and much healthier alternative than processed fast-foods and many terrestrial animal food products in the global fight against heart disease and related health ailments.

The apps for drawing are present in our children's life. Nevertheless, little is known about the impact of mobile technology on the freehand drawing educational activity. There are few works which are contextualised within short periods of time, with teachers who are not theirs and, in some cases, outside the children's classroom. In this paper, we are focussed on the use of technology on freehand drawing activity. Thus, we have compared the graphics produced by 4- and 5-year-old children with paper&crayon in comparison with those with tablet-finger. Children made the drawings during a planned free-drawing activity, in their ordinary classrooms, with their teachers and during five sessions. Assessment of drawings has evidenced tablet feasibility for making graphics. Nevertheless, with the passing of time, quality of graphics (tablet-finger vs paper&crayons), are nearly matched, demonstrating the low impact level technology has on this activity. In addition, if drawings are analysed specifically according to ages, results have shown that both groups have to develop adaptation strategies of visual perceptual skills and fine motor skills for the touch screen in order to obtain the same quality in the drawings made on both support types.

The purpose of this note is to point out a problem related to stress-strength models in some published papers. This difficulty has occurred in the asymptotic variance of the maximum likelihood estimator of the stress-strength parameter. The asymptotic variance will be studied in general and then in the mentioned papers. Finally, the correct version of asymptotic variance is computed. [ABSTRACT FROM AUTHOR]

The mechanical properties of fiber metal laminates (FML) are influenced by several various factors. Interface adhesion plays a particularly crucial role in interlaminar strength. Enhancing the interlaminar strength of carbon fiber reinforced aluminum laminate (CARALL) composites present a persistent challenge due to inherent weaknesses between metal and composite elements. Therefore, this study focuses on improving the interlaminar performance of CARALL composites by introducing cellulose paper interlayer at the metal/composite interface. The cellulose paper interlayer offers the advantage of being cost-effective and sustainable. Cellulose paper-interleaved CARALL composites were fabricated by vacuum bagging method and exhibited noteworthy improvements in mechanical properties. Comparative analysis with pristine samples revealed substantial enhancements, including a 15% increase in tensile strength, a remarkable 42% improvement in flexural strength, and a significant enhancement in mode-I fracture toughness by 65%. Furthermore, the cellulose paper interleaving played a crucial role in stabilizing fracture formation at the fiber-matrix interface, with mode II fracture toughness witnessing a 3% increase. Visual examination revealed the underlying toughening processes occurring in the interfacial area. This innovative approach of interleaving laminated composites with cellulose paper emerges as a sustainable and effective strategy, demonstrating the potential to fortify and toughen the interlaminar zones of CARALL composites.

AbstractThe present paper is the second of three, constituting a whole project of translation and commentary composed of translated extracts from the “Catalogo n. 2 – Le madri di tutte noi,” published by the Milan Women’s Bookstore in 1982. The idea for the project was conceived by Silvia Niccolai and Angela Condello, who selected the extracts and provide the written commentaries on the original texts. The Yellow Catalogue, in which we find collective discussions, pages of personal diaries and, overall, the enterprise of a group of women debating over their literary symbolic mothers (who to read? And why?), is an interesting example of political use of literature. After forty decades from its publication, it still proposes inspiring and fresh suggestions for feminist political action and critique, while representing an interesting occasion for researching the philosophical roots of Feminism. The projects is composed like follows: Paper No1, In search of a feminine symbolic, by Angela Condello, already published on Law & Litterature and Paper No2, From Novels to the Figures, themes and strategies for a political practice. Paper No 2 is structured in two parts. Part One is the article here presented (Part One. “Interest in Reality.” For every woman’s autobiography) written by Silvia Niccolai; Part Two is the article Sexual difference: an occasion for being, coauthored by Angela Condello and Silvia Niccolai, which will be published in a forthcoming issue of this Journal.

The high production of paper, followed by a more significant concern with environmental and economic issues, has led to greater relevance to paper recycling and its raw uses as composite filler. Composites of polypropylene with 10, 20, and 30 wt.% of recycled office waste paper were produced by injection molding and characterized by mechanical and thermal properties. All composites presented a slight reduction of 15°C in thermal stability compared to the polymeric matrix. Moreover, as the filler amount increased, the degree of crystallinity was reduced proportionally. The mechanical test showed similar tensile strength values among neat polymer andcomposites but also showed an increase in the composite's tensile modulus, related to the stiffness of the natural filler. The composite with a higher percentage of waste paper (30 wt.%) maintained equivalent properties as neatpolypropylene and other composites (10 and 20 wt.%). Thus, 30 wt.% composites proved to be an excellent material with less synthetic polymer percentage, keeping thermal and mechanical properties comparable to the neat PP. Furthermore, this composite does not need chemical treatment or additives harmful to the environment. It is suitable for future applications in various plastic products such as packaging and domestic utensils. [ABSTRACT FROM AUTHOR]

In addition to the large volume, the generated wastewater in paper and cardboard recycling industry contains various organic compounds and dyes. Treatment of these wastewaters is difficult due to the diversity of contaminants and the complexity of their chemical structure. This study aimed to investigate the efficiency of the coagulation and flocculation process by the new mixture of coagulants for wastewater treatment in one of the paper and cardboard recycling industries. To determine the efficiency of the coagulation and flocculation process in removing the parameters, including turbidity, colour, TSS, and COD, the Jar Test was used in laboratory conditions. By changing the variables, such as pH, coagulant type (PAC/MgCl2, PAC/Polymer, MgCl2/Polymer, MgCl2/PAC, PAC/MgCl2/Polymer), coagulant dose, and polymer dose, the optimal conditions were determined. Based on the results, the highest turbidity removal efficiency was achieved for the combination of coagulant and coagulant aid (PAC/MgCl2/Polymer) at pH 11. According to the experiments, the highest removal efficiency of turbidity, colour, COD and TSS were95.43%, 25.16%, 16.16%, and 83.33%, respectively. According to the obtained results, the coagulation and flocculation is a suitable method to remove turbidity and suspended solids in the paper and cardboard recycling industry wastewater. However, in order to remove more colour and COD, additional treatment is required. [ABSTRACT FROM AUTHOR]

Depoliticization has emerged as a key concept in analyzing the changing political dynamics of capitalist democracies. Yet, the concept of public interest has been relatively absent in depoliticization literature. This article argues for a more systematic inclusion of public interest politics in scrutinizing de- and repoliticization. The argument is advanced through strategic-relational theory by interpreting public interest as (1) a terrain of political struggles, (2) a mode of doing politics and (3) a method of enquiry. These dynamics are examined in the empirical context of Finnish forest industry's political strategy in the Kaipola paper mill closure in August 2020. The forest conglomerate UPM-Kymmene politicized its paper mill shutdown by shifting the responsibility to the centre-left governmental coalition's purportedly business-hostile policies. However, analyzing the case through UPM strategies and the paper production crisis, the closure falls in line with the forest industry's long-term business strategy. The forest industry's and UPM's strategy is recognized as a forceful defense of a corporate polity where public interest is equated with the success of key economic actors. The article concludes with an argument for the politics of public interest as a vital research perspective for analyzing contradictions surrounding 'the economy'. [ABSTRACT FROM AUTHOR]

The use of printed paper electronics in consumer goods is expected to experience a mass development in the next future. The ink used in these devices contains silver nanomaterials that may be released into the environment at the product end-of-life. We report here the first evaluation of the fate of silver during a pilot-scale recycling of printed paper electronics, made of paper printed with a cellulose nanofibrils-silver nanowire ink. We show that the released effluents are mainly free from silver, which is retained in the pulp conserved for recycling. We use atomic force microscopy experiments to show that this strong pulp-silver bond is due to the embedding of the silver nanowires in the pulp by coils of cellulose nanofibrils. We propose an estimate of the resulting adhesion stress of the nanowires to the ink, high enough to keep the silver inside the pulp during the recycling procedure. [ABSTRACT FROM AUTHOR]

The alarming global deforestation rate has great impacts on the output of the Pulp and paper Industry since wood is the principal papermaking fiber material. Although, generally, bamboo is an alternative cellulolytic fiber source, the species and culm age have great effects on its papermaking potential. Based on the methods by the International Association of Wood Anatomists (IAWA), this work assessed the characteristics of fibers from the axial culm sections of six-month plantation-grown Oxythenantera abyssinica and Beema bamboo (which was cloned from Bambusa balcoaa) for paper production. The lengths of the fibers ranged from 1.89 to 2.39 mm while the diameters were 0.025–0.031 mm. The fiber lumen diameter and wall thickness were 0.014–0.018 mm and 0.004–0.006 mm, respectively. Fibers from the species had their runkle ratios below 1, slenderness ratios above 70 and flexibility ratios above 50. These characteristics compare well with the recommendations for fibers often used for the production of packaging, writing and printing papers. Establishment of plantations of Beema bamboo and O. abyssinica is encouraged as they will serve as good raw material base for the paper industry within six months of planting. Additionally, their planting will contribute to meeting Sustainable Development Goals 1 and 13. [ABSTRACT FROM AUTHOR]

Three grades of pectin xanthates (PX1, PX2, and PX3) have been prepared by the reaction of pectin with carbon disulfide (CS2) in an alkaline medium using NaOH, via the xanthation process. The percentage yield of prepared pectin xanthates has been found to be 87.06%, 90.38%, and 93.80% for PX1, PX2, and PX3, respectively. Prepared pectin xanthates and raw pectin were utilized for heavy metals (Cu(II) and Ni(II)) and lignin enriched paper industry wastewater (LEPIW) treatment. The removal percentage of pectin, PX1, P X2, and PX3 for Cu removal at optimum condition (adsorbent dose: 5.14 g/L, pH: 5 for Cu and 7 for Ni, optimum temperature: 50°C and time: 80 min for Cu(II) and 100 min for Ni(II)) has been found as 85%, 92.33%, 93.5%, and 94.66% and 76.66%, 89.44%, 91.66%, and 93.33%, respectively, for Ni removal. The LEPIW treatment efficacy for pectin, PX1, PX2, and PX3 has been found to be 54%, 77%, 83%, and 86% for the initial COD: 2000 mg/L, pH: 7, optimum temperature: 40°C in 105 min operation time. Adsorption isotherm studies suggest that Langmuir isotherm is most appropriate which indicates adsorption follows chemisorption. The adsorption capacities of PX1, PX2, and PX3 are found as 309.59, 352.11, and 380.22 mg/g for Cu(II) and 299.40, 315.45, and 328.94 mg/g and for Ni(II), respectively, which is very high in comparison with many other recent literature studies.

To understand the degradation behaviour of rolled hanging scrolls for future conservation treatments, we evaluated the degradation–position profiles of naturally aged hanging scrolls and their model samples, which were subjected to different storage conditions. For the sample immersed in a CuSO4・5H2O solution and rolled around a glass rod, accelerated ageing using the open method (80°C, 65% RH) revealed a tendency of lower pH and higher discolouration towards the central positions, where rolling caused the most tightness. However, no clear tendencies were observed for the concentration variations of organic acids. The degradation effects of the organic acids emitted from the paulownia wooden box were also examined using the sealed tube method by enclosing the rolled painting paper and acidic paper containing organic acids together in a glass tube. Large amounts of oxalic and formic acids were detected at the periphery and scant migration of the organic acids was observed towards the centre, thus indicating that the central positions of the painting paper were less susceptible to the influence of the organic acids emitted from the external environment. By contrast, glycolic acid diffused towards the centre. The analysis of two naturally aged hanging scrolls showed different degradation behaviours. One sample, stored open in the rolled state, showed severe discolouration with the naked eye at the outermost back surface of the scroll. This was possibly associated with the large amount of sulfate ions originating from the external atmosphere, which kept the pH lower and increased discolouration towards the peripheral positions of the painting paper. For the sample stored in a paulownia wooden box, discolouration was not observed with the naked eye at the outermost back surface of the scroll, although lower pH and higher discolouration were observed towards the central positions.

The present study aims to highlight the features of Connected Papers, a visual tool that can help researchers find and explore academic papers in their literature search. The authors describe how Connected Papers allow to create a network of all the literature available related to a chosen paper. One can use Connected Papers to pull together related papers on a chosen topic and see prior and derivative works based on that topic. Using the Connected Papers tool authors attempt to visualize the key literature on the topic "Blockchain in libraries." To date, most Blockchain technology applications in libraries are still in the conceptual stage. However, sooner or later, the development and implementation of the technology are expected to facilitate the transformation of how libraries provide services and organize information. This study contributes to examining the research being done to explore the potential of Blockchain technology in libraries through mapping and visualization. The paper is original in terms of the Visual tool used "Connected Papers." [ABSTRACT FROM AUTHOR]

The pulp and paper industry converts roundwood and recycled fibre, collected from wastepaper into printing and writing papers, and other specialty grades of paper. The pulp and paper mills in Ontario have been facing extreme competitive pressures, which have affected their performance leading to several mill closures. The purpose of this study is to evaluate and compare the relative performance of three types of Ontario's pulp and paper mills (using all fibre, only roundwood fibre, and only recycled fibre). This study uses bootstrap data envelopment analysis in analyzing and comparing the operational efficiency of the Ontario's pulp and paper mills, with 224 sample data observations over a period of 17 years. The results indicate low levels of overall technical and managerial efficiencies in the pulp and paper mills using recycled fibre. The results of the study highlight that the pulp and paper industry needs to divert their attention to streamlining the manufacturing processes, reducing costs, improving raw material usage, and making capital investments in the new and improved technology, in order to improve the operational efficiency and competitiveness of the Ontario's pulp and paper mills. The pulp and paper mills using recycled fibre require huge capital investments, especially for installing the latest de-inking technology. The results of this study provide policy makers with detailed performance analysis so that future input resources can be reallocated to improve the performance of the pulp and paper mills in Ontario.

Less than 65% of wastepaper can be recycled, and the remaining wastepaper may end up polluting groundwater and generating greenhouse gas emissions if disposed improperly by using traditional approaches. The concept of circular supply chain practices, which integrates circular thinking into supply chain practices that aim to reach zero waste by exploring novel business models and supply chain functions, has been proposed to address this issue. However, previous studies implementing this concept lacked appropriate methods for structuring an influential model to guide resource allocation, which caused difficulty in developing circular supply chain practices. Thus, a hybrid method is proposed to integrate factor analysis with fuzzy synthetic and decision-making and trial evaluation laboratory methods to enable visual analysis and boost understanding. The results reveal that awareness and engagement are the most influential factors in attempts to achieve zero waste, rather than the recycling, reuse and reduction practices emphasised by previous studies.

AbstractOpenAI’s ChatGPT is an advanced large language model AI that has caused both excitement and concern in academia. TurnItIn and similar software programs are widely used in higher education to detect potential plagiarism. However, the extent to which such software can identify papers produced by ChatGPT remains unclear. The current study partially addressed this question by submitting five versions of short essays about criminological topics generated from ChatGPT to the TurnItIn software. Overall, the results indicated that TurnItIn adequately detected that the essays were not original works (mean percent plagiarized score = 31%). The analyses further illustrated that ChatGPT wrote at an exceedingly high level (mean Flesch-Kincaid Grade Level = 15.1) atypical of essays in higher education. Consequently, it appears that detection of AI-generated writing may be easier than initially assumed although the technology is bound to improve. Accordingly, possible strategies for approaching AI in higher education are proposed. [ABSTRACT FROM AUTHOR]

An optimised method was established for the determination of four chloropropanols in paper straws, namely 1,3-dichloropropan-2-ol(1,3-DCP), 2,3-dichloropropan-1-ol (2,3-DCP), 3-monochloropropane-1,2-diol (3-MCPD) and 2-monochloropropane-1,3-diol (2-MCPD). After extraction with a food simulant, purification with matrix solid phase dispersion (MSPD), and derivatisation using heptafluorobutyrylimidazole (HFBI), the chloropropanols were analysed by gas chromatography–tandem mass spectrometry (GC-MS/MS), and quantified with a deuterated internal standard. Under the optimised conditions, the limit of detection (LOD) was 0.200 µg/L for the four target compounds. The recoveries were in the range of 71.4% – 119.4% with relative standard deviations (RSDs) of 0.4% – 9.9%. The method fulfilled the requirements of the European regulations for the quantification of 3-MCPD and 1,3-DCP. Fifteen paperboard straws were tested using the proposed method. The results showed that 1,3-DCP and 3-MCPD exhibited the highest detection rate among the four chloropropanols tested (93.3%). the method can be used to detect chloropropanol contamination in paperboard products, and further to guide food manufacturers to reduce the levels of chloropropanols in paperboard food contact materials.

Cellulose filter paper (CFP) was modified with poly(acrylic acid) (PAA) and/or poly(ethylene glycol)methacrylate (PEGMA), followed by Cu immobilization for 4-nitrophenol (4NP) reduction. Among these samples, Cu-immobilized CFP modified with PEGMA polymer (CFP@PEGMA-Cu) exhibited the highest Cu incorporation of 2.21%. Those having the copolymer (CFP@PAA-co-PEGMA-Cu) demonstrated the highest efficiency, completing 4NP reduction in 3 min with an impressive 99.45% conversion, a high-rate constant (k) of 27.5 × 10−3 s−1, and turnover frequency (TOF) of 18.36 h−1. Notably, the catalysts containing PAA maintained good reusability, preserving 97% conversion upon 9 cycles. These results suggest their promising applications in sustainable catalysis, offering the catalytic potential with simple preparation and low cost required. [ABSTRACT FROM AUTHOR]

Microbial fuel cells (MFCs) have attracted much interest as an alternative energy conversion technology and as a system for recovering and treating wastewater. MFC is a powerful technique for generating energy from various sources, including natural organic matter and renewable biomass. It has several possible applications, including power generation for many small electronic devices, wastewater treatment, and biosensors. However, the restricted power output of MFCs is the most significant impediment to their widespread use and up-scaling in practical applications. The anode electrode is the most critical component of an MFC, where poor anode electrode performance leads to poor MFC efficiency. Therefore, efforts have been made to modify electrodes to improve their performance. While power density is an essential metric in determining MFC efficiency, other parameters such as Coulombic efficiency, current density, cell voltage, and the removal rate of chemical oxygen demand (COD) should also be considered to evaluate the performance of MFC. This study reviews the most recent electrode modification techniques through anode treatments with metal oxides, conductive polymers, carbon nanotubes, and other chemical compounds as well as through cathode modifications. Different modified MFCs are compared in terms of their power density and the type of bacteria and membrane used. [ABSTRACT FROM AUTHOR]

One of the factors affecting the life expectancy of hanging scrolls is the storage environment. Our study focused on clarifying the degradation behaviour of painting paper, concentrating on the specific storage conditions that provide an airtight environment in a storage box and the stacked structure of the rolled paper rather than considering the materials of the wooden storage box or the gases generated from it. The degradation behaviour and rates for the sealed tube and moist heat ageing methods, excluding the additional effects of light and air pollutants, were compared. When the painting paper was immersed in a CuSO4・5H2O solution instead of a copper green pigment, the oxidation of the painting paper, attributed to Cu2+, proceeded faster with the sealed tube method than with the moist heat method. The co-occurring organic acids generated, namely glycolic and formic acids, which were secondary components, were detected in a higher amount in the first lining paper than the painting paper. This implies that the acids migrated from the painting paper into the lining paper. However, oxalic acid, which was the main component, did not significantly migrate and remained in the reaction system in the sealed tube without volatilising. This increased the hydrogen ion concentration in the painting paper and accelerated acid hydrolysis. Consequently, discolouration and a decrease in the degree of polymerisation and physical strength proceeded faster with the sealed tube method than with the moist heat method. Thus, although this result does not necessarily invalidate the storage system of a rolled hanging scroll in a box, the storage of a deteriorated hanging scroll in a closed system is expected to degrade the painting paper faster than it would in an open system.

In the present study, a kinetic model has been developed to predict the chemical oxygen demand (COD) removal efficiency of Fenton process for the treatment of pulp and paper mill (P&P) wastewater. In order to investigate the effects of main parameters including Fe(II) dosage, H2O2 dosage, and pH, 45 experiments have been carried out at three levels for each parameter, and thus COD removal efficiency has been obtained. The Fenton process was simulated by using 10main reactions, and the model was solved numerically according to a specific algorithm. All the pollutants in the P&P wastewater were assumed to be a pseudo-material, andapparent kinetic constant (k**)was calculated using a developed iterative method. The results of the numerical model indicated that the proposed model had a great potential to predict COD removal efficiency for P&P wastewater by Fenton in comparison to the first and second-order kinetic models. Accordingly, R-squared (R2), Root Mean Square Error (RMSE), and Mean Relative Error (MRE) of the numerical kinetic model were 0.93, 4.296 × 10−7, and 0.035, respectively, implying remarkable accuracy of the numerical model. Furthermore, at the optimum point of Fenton process,which was pH: 3,[H2O2]:0.015 Molar, and [Fe(II)]: 0.015 Molar, the COD removal efficiency of P&P wastewater reached 78%. As the basis of the numerical model was established according to mechanisms of Fenton process, the results demonstrated the great performance of the advanced kinetic model in the estimation of the COD removal efficiency, the behaviour of effective parameters such as pH, H2O2, and Fe(II) along with their effects on k**, and Fe(III) accumulation during Fenton process.

AbstractThe peroxidase-like properties of a graphene oxide/platinum-cobalt nanocomposite and the rapid color development mechanism of 3,3′,5,5′-tetramethylbenzidine (TMB) through the decomposition of ·OH from H2O2 were utilized to prepare a nonlabelled, simple, and sensitive paper-based colorimetric sensor. This sensor allows visualization of the results and instantaneous detection, enabling quantitative measurement of H2O2. The graphene oxide/platinum cobalt composite was synthesized using a two-step procedure. Its properties were investigated using transmission electron microscopy (TEM), Raman spectroscopy, and energy-dispersive X-ray spectroscopy (EDS). The composite was subsequently transferred onto a paper substrate to create the colorimetric sensor. The optimal catalytic conditions were a composite concentration of 201.17 µg/mL, a color development time of 3 min, a TMB concentration of 2 mmol·L−1, and a pH of 4. Using the optimal conditions, the paper-based colorimetric sensor has a linear range for H2O2 from 1.0 × 10−5 to 0.1 mol·L−1, with a limit of detection of 1.0 × 10−6 mol·L−1 which is comparable or better than comparable methods. This paper-based colorimetric sensor has potential applications for the rapid determination of hydrogen peroxide. [ABSTRACT FROM AUTHOR]

A novel approach for paper drying using airborne ultrasound technology is presented. A unique experimental setup is developed, and a systematic study is conducted using 23 factorial design of experiments and Analysis of Variance. Three controlling factors are considered in the experiments including the initial moisture content, basis weight and refining condition. The outcome of the experiments is compared to a previous work on direct-contact ultrasonic drying of paper. The results confirm that similar to direct-contact, for airborne ultrasonic drying, the basis weight/thickness of the sample is the most important factor in ultrasonic drying and it is followed by the effect of initial moisture content. Using linear regression model, a correlation for predicting the total time of ultrasonic drying is provided. Quality of the dried samples is evaluated, and the permeability measurements confirmed the effect of pore characteristics on ultrasonic drying. The analysis for energy consumption reveals that airborne ultrasonic drying is more efficient at higher moisture contents. [ABSTRACT FROM AUTHOR]

The growing awareness of the importance of bacterial-resistant surfaces has increased since the COVID-19 pandemic global problem. Therefore, the need for antibacterial surfaces has become urgent. The by-product bagasse papers (BPs) were modified with antimicrobial natural rosin, followed by the synthesised graphene oxide and silver nanoparticles (GO-Ag-NPs) through a spin coating approach. The modified samples exhibited a remarkable antibacterial activity towards E. coli (G−ve bacteria) and S. aureus (G+ve bacteria). The microstructure, as well as phase composition of the prepared composites, was identified using various techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscope (SEM) and hydrophilicity which was metered by water contact angle (WCA). The obtained results demonstrated that the halos of inhibition were noticed for decorated TBP samples by GO-Ag-NPs with various diameters ranging from 20 to 25 mm. Consequently, packaging applications could be extra developed with these renewable nanomaterials. [ABSTRACT FROM AUTHOR]

In this article, protic ionic liquids (PILs) and deep eutectic solvent (DESs) were explored to enrich the cellulose content of a paper mill sludge (PMS) received from a sanitary paper manufacturing plant. Compositional, morphological, physico-chemical, and thermal decomposition features of PMS were monitored using XRF, SEM, FTIR, XRD, and TGA. Triethylammonium hydrogen sulfate (TEAHSO4), which functioned selectively for the elimination of mineralogical content and cellulose enrichment of PMS, enhanced the cellulose content of the material from 45% to 74% following the pretreatment at 150 °C. Though DESs such as choline chloride-urea behaved poorly toward demineralization relative to PILs, they preserved cellulose effectively in the structure and gave satisfactory saccharification yields that reached over 90%. In addition to integrating the sustainable benefits of PILs and DESs into the valorization of PMS for the first time in literature, this work highlighted the competency of PMS as a cellulose-rich feedstock for biorefinery applications.

Time-limited exposure of electrode-free optically rewritable electronic paper is essential for applications, but performance characteristics can be modest. In this study we investigate whether image writer mode can improve kinetics of the photosensitive layer order parameter, which is described by the rotational diffusion model. The model that we developed allows adjusting the transmittance spectra of polarisers. We have found that fairly uniform transmittance spectra of polarisers enable to obtain competitive contrast ratio of 8:1 within 10 s of exposure. In comparison with the long-time exposure, the reflectance coefficient reduces by 24%. Computer-simulated image is consistent with the experimental observations. [ABSTRACT FROM AUTHOR]

This article discusses a scoping review of position papers aimed at enhancing the quality of life of people with intellectual disabilities. It describes the approach taken to conducting the scoping review and the position papers identified, and goes on to explore a range of issues that became apparent when carrying out the review. The authors argue that the people whose lives are most centrally impacted by position papers—people with intellectual disabilities and their families—should be included in the production and review of those papers. The article concludes by recommending a co-ordinated approach to the production and storage of position papers. [ABSTRACT FROM AUTHOR]

To study the life expectancy and difference in aging resistance properties of different modern repair bamboo papers, hydrothermal/dry-heat ageing experiments on repair bamboo paper samples were conducted. The mechanical strength (tensile strength and folding endurance) of different papers during the ageing process were analyzed. Furthermore, the chemical properties (degree of polymerization and pH) of the samples were tested to search for the immanent cause of paper ageing. The results indicated that the ageing resistance ability and durability of modern repair paper are strongly related to their production process, which corresponds with the initial properties of the paper. Mechanical pulp had a low degradation resistance, which was further exacerbated by the chemical bleaching process. In the long run, traditional handmade papers with solar bleaching processes will have longer-term stability and durability. [ABSTRACT FROM AUTHOR]

This study investigated an under-researched source of measurement error in high-stakes examinations, namely mistakes in examination papers (e.g. multiple-choice questions containing more than one correct answer). Such mistakes (henceforth errors) are important, as they can undermine students’ performance in the examination, while also eroding public confidence in the examination system. In light of this, this study sought to understand what gives rise to such errors. To this end, it drew upon in-depth interviews with 36 assessment professionals with knowledge and experience of the examination paper construction process. Through illuminating the demands of the paper construction process and the characteristics of the people who are involved in it, this investigation identified a number of ‘active’ and ‘latent’ human failures that can lead to errors in examination papers. The article argues that, to minimise the risk of error in examination papers, efforts to ‘adapt’ people to the demands of the paper construction process should be carefully combined with efforts to adapt the paper construction process to people requirements. Apart from contributing new knowledge to the field, the study’s findings have also practical implications: examination providers can use them to optimise their paper construction processes to enhance the quality of their assessment instruments.

mHealth applications (apps) are tools that can enhance research by efficiently collecting and storing large amounts of data. However, data collection alone does not lead to change. Innovation and practice change occur through utilisation of evidence. The volume of data collected raises questions regarding utilisation of data by nurses and midwives, and how data from mHealth apps can be used to improve person-centred practice. There is limited empirical evidence and a lack of direction from global health authorities to guide nurses and midwives in this area. To describe strategies for nurses and midwives that could enhance the effective use of data generated by mHealth apps to inform person-centred practice. The purpose of this paper is to stimulate reflection and generate actions for data utilisation when using mHealth apps in nursing research and practice. This discussion paper has been informed by current evidence, the integrated-Promoting Action on Research Implementation in Health Services (i-PARIHS) framework, and research experience as part of doctoral study. Before engaging in data collection using mHealth apps, nurses and midwives would benefit from considering the nature of the evidence collected, available technological infrastructure, and staff skill levels. When collecting data and interpreting results, use of a team approach supported by engaged leadership and external facilitation is invaluable. This provides support to operate apps, and more importantly use the data collected to inform person-centred practice. This paper addresses the limited available evidence to guide nurses and midwives when using mHealth apps to collect and use data to inform practice change. It highlights the need for appropriate technology, external facilitative support, engaged leadership, and a team approach to collect meaningful evidence using mHealth apps. Clinicians, leaders, and researchers can apply the strategies provided to enhance the use of mHealth apps and ensure translation of evidence into practice. [ABSTRACT FROM AUTHOR]

This article investigates from the WPR approach how educational digitalization is discursively constructed in China by analysing how policy papers construct different kinds of subject positions for educators and the educated. The paper identifies non-coherences at two levels. First, digital technology is alternatively profiled as a solution and as a cause of problems. Second, the subjectivities ascribed to educational actors oscillate between opposing poles. Students are expected to be creative, critical thinkers and they are required to leave crucial decisions over what to learn to digital tools. Teachers are seen as deserving technological support in the handling of countless tasks, and they are presented as objects of distrust. Parents are portrayed as deficient beings in need of re-education and as influential players entitled to monitor students and teachers. This article reveals a particular Chinese style of governance which encourages self-management and imposes disciplinary techniques. [ABSTRACT FROM AUTHOR]

My comments concern the significant errors in the crystallographic part of the commented paper. The diffraction patterns are erroneously analysed and the final chemical composition is different than those supposed in the paper. There are also some manipulations with data. [ABSTRACT FROM AUTHOR]

We investigate two research questions using a recent statewide transition from paper to computer-based testing: first, the extent to which test mode effects found in prior studies can be eliminated; and second, the degree to which online and paper assessments offer different information about underlying student ability. We first find very small mode effects for a more recent transition in Massachusetts. Second, we investigate the predictive evidence of validity for paper and online tests for predictions of future test scores and grades. We generally find minimal differences for the extent to which scores on paper tests can differentially predict future online versus paper test scores. Finally, online and paper test scores are similarly predictive of future grade point average. We conclude that the online test penalty can vary substantially by test and that extreme care should be taken when administering online tests to some students and paper tests to others.

This paper investigates retracted articles indexed in the Scientific Electronic Library Online (SciELO) Brazil, using bibliometric techniques to identify the characteristics of these retractions and relevant citation trends. All records of retracted articles from the first record in October 2004 to April 2022 were included. Sixty-seven retractions and 870 citations pre- and post-retraction were analyzed. Results indicate a change of scenario that began in 2015, with recurrences of retracted articles allegedly produced by paper mills. The prevalence of retractions derived from professional misconduct in health research and the frequency of post-retraction citations in health sciences raise concerns in the chain of stakeholders, public health, and scientific development.

BackgroundMethodsResultsDiscussionConclusionsThis paper considers weaknesses in a study by Cohen et al. (2006) on the impacts of community singing on health. These include high demand characteristics, lack of attention to attrition, flawed statistical analysis, and measurement. Nevertheless, the study is uncritically cited, in evidence reviews, with findings taken at face value.Google Scholar, SCOPUS and BASE citation functions for Cohen et al. identified 32 evidence reviews in peer-reviewed journals. Eleven of these reviews, published between 2010 and 2023, focused on creative arts interventions.We demonstrate limitations in the Cohen et al. research which undermine the conclusions they reach regarding the health benefits of group singing. Subsequent evidence reviews take the findings at face value and offer little critical commentary.We consider what is needed to improve evidence reviews in the field of creative arts and health research.A more robust approach is needed in reviewing research evidence in the field of arts and health. The Cohen et al. paper is not suitable for inclusion in future evidence reviews. [ABSTRACT FROM AUTHOR]
