This paper examines the feasibility of extracting cellulose from tissue paper wastes (TPW’s) using several methods: sonication (SC), subcritical (SU), microwave (MC), and microwave with diluted acid (MA). The chemical characterisation and morphological properties of nanocrystal cellulose were investigated using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and scanning electron microscopy with energy dispersive X-Ray analysis (SEM-EDX). TPW’s have a relatively high crystallinity index (CrI = 61.02%). It was found to be lower than that for cellulose extracted using SU and SC MC, MA methods, where CrI to 65.65%, 68.07%, 69.21% and 73.42%, respectively. The MA method yielded cellulose with the highest CrI and altered surface morphology. This cellulose was selected for cellulose acetate synthesis. After acetylation, the CrI decreased to 61.45%, and the morphological aspect was changed. In conclusion, nanocrystal cellulose was successfully extracted from TPW’s and effectively changed to its esterified form. [ABSTRACT FROM AUTHOR]

Conference proceedings are valuable sources for research, providing insights into individual or organisational projects. Australian library and information services (LIS) professionals have the opportunity to contribute to a robust conference culture, including the biennial library technology VALA conference. Practice-driven conferences can offer interpretations of LIS practitioner experiences, however, there is limited research focusing on Australian LIS conference proceedings. The VALA conference papers offer a unique record of technology's impact, influence, and implementation in Australian LIS organisations over the last forty years. This article will outline the objective and methodology of an ongoing research project undertaking historical analysis of VALA conference papers. The research project seeks to examine key themes, theories, and tools discussed in VALA conference papers and will attempt to identify if evolving technology influences the practices and attitudes of Australian LIS practitioners. The article will identify the research methods and the content analysis techniques that will be used in the project, and present preliminary results from a pilot study presented at the 2023 RAILS conference.

The complex mixture of pollutants found in industrial effluents creates a significant environmental challenge. Enzymatic treatment offers a promising alternative to traditional physiochemical techniques. With an emphasis on laccase enzymes, this review examines the potential of both free and immobilized biocatalysts for the treatment of industrial wastewater, especially from pulp and paper mills. Laccase has become one of the most popular options for bioremediation because of its broad substrate specificity and capacity to break down different kinds of organic pollutants. The different methods of laccase immobilization, including adsorption, encapsulation and cross-linking are examined, exploring their advantages and limitations. The benefits of immobilization for enzyme stability, reusability and operational efficiency in wastewater treatment processes are further discussed. By comparing the advantages and limitations of free and immobilized biocatalysts, this review aims to provide valuable insights for the development of efficient and sustainable enzymatic strategies for industrial wastewater treatment. Furthermore, this paper offers future possibilities for using biocatalyst in pulp and paper waste treatment. [ABSTRACT FROM AUTHOR]

Objectives. This study aimed to investigate 12-month and 7-day prevalence of musculoskeletal symptoms among workers of the pulp and paper industry, and assess the contribution of age, gender, body mass index (BMI) and physical activity (PA). Methods. The sample comprised 904 workers. Musculoskeletal symptoms were assessed using the Nordic musculoskeletal questionnaire. χ2 tests assessed the association between musculoskeletal symptoms and age/gender/BMI/PA, and multivariate logistic regression models predicted the 12-month occurrence of symptoms in the five most prevalent regions. Results. The five most affected body regions were the lower back, shoulders, neck, knees and wrists/hands. Older workers presented more symptoms in all body regions, except dorsal; female gender was associated with neck symptoms (p = 0.001); overweight was associated with a higher prevalence of lower back (p = 0.01), knee (p = 0.017) and ankle/foot (p = 0.037) symptoms; and a moderate PA level was associated with thigh/hip symptoms (p = 0.006). Age was a significant predictor in all five most affected regions; gender was a significant predictor for shoulders, neck and wrists/hands; and BMI was a significant predictor for lower back symptoms. Conclusion. The 12-month and 7-day prevalence of musculoskeletal symptoms among workers of the pulp and paper industry is higher in the lower back, shoulders, neck, knees and wrists/hands.

In this paper, a smartphone-assisted detection integrated with paper-based analytical device (PAD) functionalised with green emissive carbon dot (g-CDs) has been designed for on-site selective detection of Fe3+ ions. g-CDs have been prepared by one-step hydrothermal process using 4-aminophenol and ethylenediamine (EDA) as precursors. g-CDs were highly stable for more than three months in aqueous solution with a strong green emission, λem at 513 nm and 30.33% as a fluorescence quantum yield. Interestingly, Fe3+ selectively quenched the fluorescence intensity of the g-CDs and the quenching mechanism can be attributed to static quenching. Furthermore, under the optimal conditions, using conventional fluorimetry, the g-CDs could detect Fe3+ ions with a linear relationship from 0 to 90 μM (R2 = 0.9970) and the limit of detection was 0.35 μM. Visual mode integrated with smartphone detection on PAD was successfully prepared after loading g-CDs on the paper. The fluorescent colour variations of g-CDs on PAD were monitored under the UV lamp using smartphone for capturing images. The green channel intensities of images of the circle zones were processed using Colour Grab App for the RGB analysis. A linear working range was obtained from 0 to 0.8 mM, and the limit of detection was 0.05 mM. The PAD was used successfully for the detection of Fe3+ ions in human serum with a recovery from 87.93% to 96.86%. [ABSTRACT FROM AUTHOR]

Computer programming is essential nowadays but still challenging to learn due to its invisible thinking. Current programming environments are mostly designed for operating on computers directly to learn concrete programming, but this approach lacks the support for clarifying learners' thinking processes. On the other hand, using paper and pens shows usability in developing creative thinking, but it cannot help verify learners' thinking results due to its nature. To benefit from both paper and computers, we developed an interactive programming learning environment consisting of a paper board game, a computer system, and a digitalization mechanism. Learners can use the learning environment to draw down their thinking results and verify them by comparing them with the evaluation on the computer system immediately. Two experiments were conducted to compare this learning environment with paper board games and computer programming environments, respectively. The experimental results show that the subjects who learn in our environment can learn to program better than those who learn with the other two. The proposed environment is easy to prepare for learners in a classroom as their first step to programming learning. It can help learners cross over from paper board games for computational thinking to computer programming environments. [ABSTRACT FROM AUTHOR]

This study evaluates the impact of sales promotions that are featured in store flyers distributed by prominent retailers and their capacity to attract consumers to their establishments. A distinctive conceptual framework is introduced that scrutinizes the influence of ethically-minded consumer behavior, digital citizenship/literacy, and a retailer's orientation toward environmental sustainability and explicit ecological concerns. A quasi-experimental design was used to formulate four distinct scenarios from a possible set of eight, stemming from the combinations of three variables: 2 Retailer Positioning (green vs. without explicit ecological claims) × 2 Flyer Mediums (paper vs. digital) × 2 Discount Levels (5% discount vs. 30% discount). Through an online survey, a sample of 269 responses was garnered to gauge consumer reactions to these store flyers, evaluating their attitudes and receptiveness. The findings suggest that attitudes toward paper flyers were more favorable when presented by non-green retailers compared to their green counterparts. This can be attributed to a perceived inconsistency between a green brand positioning and the use of paper flyers. Furthermore, the propensity to transition to digital flyers was notably stronger for green retailers compared to non-green retailers, but this inclination was most pronounced when higher discounts were offered.

In this work, we describe a simple strategy for the preparation of a low-cost electrode material based on polypyrrole (PPy) film grown on an insulating cellulosic paper substrate via in-situ oxidative polymerisation technique and functionalised by silver nanoparticles (AgNPs) uniformly dispersed on its surface. The properties of the obtained AgNPs-PPy composites were characterised using X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray analysis. The electrocatalytic activity of the prepared electrode was investigated for the electroreduction of nitrate using cyclic voltammetry in 0.1 M KOH solution. Results demonstrated that the incorporation of AgNPs into the PPy matrix improves significantly the catalytic behaviour of this film. The effect on the electrode response of the amount of the incorporated AgNPs was also investigated. This paper highlights a simple procedure for the making of low-cost paper electrodes for the efficient reduction of nitrates. [ABSTRACT FROM AUTHOR]

BackgroundObjectiveMethodsFindingsConclusionsImpact statementPlain English SummaryThe Australian Commission on Safety and Quality in Health Care ‘National Standards’ require general hospitals to have systems for clinicians to recognise and respond to patients’ deteriorating mental state. The lack of an evidence-based operational definition and clear guidance challenges this requirement.To review governance mechanisms and assessment processes for deteriorating mental state in a metropolitan general hospital and propose an organisational framework.A qualitative document analysis using the READ approach systematically reviewed hospital committee reports, health district policies, and training programs to identify and synthesise key assessment points and processes.The study mapped assessment points for recognising and responding to deteriorating mental state across patient journey stages. An organisational systems infographic provides a blueprint for meeting National Standards accreditation criteria.Hospitals should establish comprehensive systems to observe, monitor, assess, and refer individuals with deteriorating mental state, involving multiple governance processes and frameworks.Our paper maps governance and assessment processes to enhance deteriorating mental state recognition in general hospitals, aligning with National Standards.General Hospital staff often need to recognise and respond to patients whose mental health is getting worse. This problem is serious because a worsening mental state can lead to harmful behaviours, such as self-harm or violence, and can result in poor healthcare experiences for patients. Our paper aimed to find ways to help hospital staff better identify and manage these situations. We looked at the systems and processes currently in place in hospitals to see how they could be used to meet national healthcare standards for mental health care. We created a detailed plan that hospitals can follow to improve their mental health responses. This plan includes steps for governance, assessment, and clinical pathways, ensuring that all parts of the hospital system work together to support patients with deteriorating mental states. Our findings suggest that using existing hospital processes, rather than creating new tools, can help staff more effectively recognise and respond to mental health issues. This approach not only meets accreditation requirements but also enhances patient safety and care quality. This paper provides valuable insights for healthcare practitioners and policymakers, showing that with the right systems in place, general hospitals can better manage mental health care, ultimately leading to better outcomes for patients.

This paper questions the hyper fixation on papers in producing citizens or proving citizenship, arguing that not papers but the agglomeration of legal, bureaucratic and social processes produce citizenship in Assam's Foreigners' Tribunals (FTs). Based on ethnographic fieldwork with members (presiding over cases), lawyers, border police officials and victims of citizenship examination processes, this paper shows that citizenship cannot be easily proved or disproved based on the possession or absence of papers, as the 'truth' about one's citizenship is produced equally outside these courts. One's citizenship status inside the court depends on a series of procedural, documentary and certificatory correlations accompanied by social performances (testimonies from family and community members). This is contingent on the truth produced outside through the suspicion of being a 'foreigner', easily cast in terms of one's physical appearance, social class, religion and language. Community structures outside courts also enable certain groups to be documented easily, aiding the production of the legal truth required inside for establishing citizenship status. Therefore, the way suspicion is informed and legal technicalities are deployed to generate information and knowledge along with the role of family and community social networks all contribute towards establishing one as a citizen or a 'foreigner'.

AbstractGraphene quantum dots (GQDs) were used for surface modification of a screen-printed paper electrode (SPPE) for the development of a mobile phone-integrated immunosensor for the detection of scrub typhus. GQDs were synthesized from a 1.8% starch solution via a hydrothermal method and characterized by ultraviolet–visible (UV–Vis) spectroscopy, fluorescence, Fourier transform infrared spectroscopy and dynamic light scattering. Furthermore, anti-56 kDa type specific antigen (TSA) antibodies were used for immobilization on the GQD-modified SPPE working electrode using EDC/NHS (N-ethyl-N′-(3-(dimethylamino)propyl)carbodiimide/N-hydroxysuccinimide) (1:1) chemistry. The TSA antigen was used at different concentrations to interact with specific antibodies, and the response was recorded via cyclic voltammetry, differential pulse voltammetry and electrochemical impedance spectroscopy using potassium ferricyanide K4[Fe(CN)6]− as a redox indicator. The developed immunosensor showed an excellent sensitivity of 17.40 µA cm−2 ng−1 and a limit of detection of 0.399 ng µL−1. The developed immunohybrid sensor is a novel mobile phone-integrated, highly specific and stable platform for Orientia tsutsugamushi. [ABSTRACT FROM AUTHOR]

Previous research has documented that students' reading comprehension performance in learning English as a foreign language (EFL) differs greatly between mobile-assisted and paper-based reading. The present study extends previous work by investigating whether reading cognitive load differs between mobile-assisted and paper-based EFL reading processes and exploring whether cognitive load mediates the relationship between reading medium and EFL reading comprehension performance. The instruments used are reading comprehension tests and questionnaire surveys administered to a sample of 191 first-year college students. A repeated-measures analysis of variance (ANOVA) indicates that cognitive load is significantly greater for mobile-assisted EFL reading than for paper-based EFL reading. In addition, structural equation modeling analyses indicate that cognitive load fully mediates the relationships between medium and reading comprehension performance; these mediation effects are independent of the level of English language proficiency. These results imply that cognitive load is a pivotal factor influencing students' reading comprehension across media. Reasons for differences in reading cognitive load and its role as a mediator are discussed. Recommendations for promoting students' reading experience on mobile phones are provided.

AbstractIn the rapidly evolving wireless communication landscape, achieving full-dimensional coverage poses a gamut of challenges such as intricacy, high hardware costs and energy consumption. In addressing these issues, reconfigurable metasurfaces are being considered as a potential solution. However, traditional methods of producing reconfigurable metasurfaces via printed circuit board (PCB) technologies possess limitations such as high cost and extended production cycles. Particularly, in the context of large-scale communication scenarios, reconfigurable metasurfaces can also present high energy consumption issues. Therefore, this paper proposes a novel type of intelligent reflection surface (IRS) characterized by lower production costs, reduced energy consumption, enhanced flexibility, ease of manufacture, and superior electromagnetic wave modulation capabilities. The proposed reconfigurable smart metasurface is a paper-based metasurface printed with conductive ink, which uses conductive ink to draw base metal blocks on a flexible substrate, and uses silver-tin as a metal patch between the metal blocks, and the phase response is reconstructed with silver ink. By adjusting the distribution of these metallic patches, we tailor the phase and amplitude distributions to generate specific scattering effects. This paper presents designs of six patterns that yield single-beam and dual-beam, with experimental results aligning closely with simulated results, validating the feasibility of the proposed method. This low-power, low-cost, and efficient IRS is expected to pave a new path for advanced 5 G/6G wireless communication technologies. [ABSTRACT FROM AUTHOR]

As cousins, we discovered a treasure trove of family papers, revealing the intricate relationship between precarity and privilege of our family from Salonica navigating the post-Ottoman transition. Recognising the potential of family history to provide a more intimate and complex historiography, this article offers our initial study of these family papers. By highlighting the challenges posed by the scarcity of such documents in Middle Eastern studies, emphasising women's roles in preserving family memory and focussing on the interplay between personal and political domains, we identify the preparation of a family tree as a gendered and socioeconomic project of preserving the past and shaping the present. By tracing our family's origins, including unsettling discoveries, we address matters of identity and memory before embarking on our analysis. By reconstructing the biographies of two generations, we characterise the family's socioeconomic struggle to sustain their precarious privilege amid shifting frontiers and along their journey from Ottoman Salonica to Kemalist Turkey. Ultimately, this article underscores the significance of family history as a transnational, intergenerational, intersectional and social history that enriches our understanding of the post-Ottoman transition through the lives of ordinary (and some extraordinary) Ottomans.

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.

The vision of the International Menopause Society (IMS) is that all women across the world will have easy and equitable access to evidence-based knowledge and health care, empowering them to make fully informed midlife health choices. The aim of this White Paper is to provide a well-balanced educational narrative of the menopause and menopause hormone therapy (MHT) from IMS experts, leading into World Menopause Day 2024. This is achieved by exploring the anthropology and history of menopause, the principles and controversies of prescribing MHT, and by placing this into regulatory and menopause society contexts. The White Paper also lays the groundwork for the forthcoming updated IMS recommendations on menopause and will act as a blueprint for the future ethical management of menopause from practical and aspirational perspectives. An important section of the paper is 'The 5Ws of prescribing MHT': WHO is MHT for; WHAT types and doses of MHT; WHEN should MHT be started and stopped; WHY is MHT important; WHERE can MHT be accessed? A key points summary of this information is provided for healthcare professionals and the public. The summary provides 'easy to access' advice regarding several recent controversial MHT prescribing issues in the healthcare and media spotlights. [ABSTRACT FROM AUTHOR]

This work engages with Karen Barad's philosophy and theory of agential realism through research practices of critical autoethnography and arts-based methods. The work explores how knowledge, memory, language, and experience remain alive within practitioners and inform who we become and how we inherit the stories involved in being educators and therapists. This paper presents two entangled research processes involving engagement with material artefacts related to the author's professional identity development and practice as an arts therapist in Aotearoa, New Zealand. Through Barad's theory of diffraction, engagement with and reassembling research artefacts supports a consideration of what can happen when we map and remember stories from different times and spaces in our lives. Elucidating and exploring the contours of memories and experiences can be helpful practices to engage in as narrative is the most potent mechanism for memory and teaching, and as therapists and educators, we are living through and practicing from the tangle of these narratives.

AbstractFluorotelomer-based acrylate polymers and surfactants used to grease-proof food contact paper (FCP) are potential sources of dietary exposure to perfluoroalkyl substances (PFAS). Food contact substances (FCS) containing polyfluorinated long-chains (≥C8) were voluntarily removed by their manufacturers from the U.S. market in 2011 due to health concerns and largely replaced with FCSs containing short-chain (≤C7) PFAS. In 2020, FDA findings of potential biopersistence of 6:2 FTOH (CF3(CF2)5CH2CH2OH) similarly prompted an additional voluntarily phase-out of FCSs containing 6:2 FTOH by their manufacturers that was completed by the end of 2023. To monitor the phase-out process, a screening method was developed to detect FCPs containing ester-linked polyfluorinated pendant chains. Direct Analysis in Real Time-Isotope Dilution-High Resolution Mass Spectrometry (DART-ID-HRMS) enabled rapid semi-quantitative detection of 6:2 FTOH in FCP saponification reaction headspace without requiring sample concentration or chromatography. 19F-NMR analysis confirmed 6:2 FTOH pendant chain identity and detection dependence on saponification. The speed and specificity of this approach arise from ester saponification in the presence of stable isotopically labeled 6:2 FTOH; high FTOH differential volatility relative to nonfluorinated matrix, and the facile production of FTOH gas-phase anions (e.g., [M + O2]·−, [M-H + CO2]−) under ambient ionization conditions. The efficiency of this simple workflow makes it well-suited for monitoring the phase-out of FCS containing ester-linked polyfluorinated chains from the U.S. marketplace. [ABSTRACT FROM AUTHOR]

Positive academic climates are critical to helping students thrive, and kindness innovations might enhance these climates. This conceptual paper's purpose is to share insights from a consensus building event focused on fostering relationships and knowledge-sharing among an international group of multidisciplinary students, faculty, and staff who explored ways to bring a kindness framework into post-secondary education. Participants underscored kindness as critical for students' experiences and university culture, and identified several levels of influence requiring intervention focus. Ideas and strategies emerging from the event might serve to encourage student-led kindness initiatives and prompt university personnel to integrate kindness into post-secondary institutions.

Stanley Kubrick's project on the Holocaust, Aryan Papers, was dear to his heart. He worked on it for a long time, but he could not, in the end, bring himself to complete the planned film. This article canvasses some of the reasons other scholars have supplied for this film remaining unmade, including the notion that the Holocaust is unrepresentable. However, it points to a novel explanation. I argue that Kubrick's plot modifications, particularly to the conclusion, doomed the project. Specifically, Kubrick has a Jewish woman take revenge for war-time atrocities. Discussing revenge in relation to the Holocaust has until recently been as impious as representing the Holocaust itself. Jewish revenge was unfashionable in Holocaust films of all kinds when Kubrick was working on Aryan Papers in the early 1990s. Kubrick's planned film was generically ahead of its times. The vengeful Jewish woman had to wait for Inglourious Basterds in 2009. [ABSTRACT FROM AUTHOR]

This article asks why Stanley Kubrick's longstanding wish to direct the film version of Louis Begley's 1991 novel Wartime Lies never came to fruition. In Begley's novel, the protagonist Maciek recounts the experience of living in hiding under a false identity in Nazi-occupied Poland. Kubrick drafted a series of quite different plotlines and conclusions for the film version, to be called Aryan Papers, in which Maciek's aunt Tania takes a highly dramatic role in their destiny. The more Kubrick changed Aryan Papers, in response to the pressure of Hollywood expectations and the cultural valorization of active Holocaust resistance, the less it resembled the very work he had chosen to adapt. This impasse shows why the director could not ultimately bring Aryan Papers to the screen. [ABSTRACT FROM AUTHOR]

The addition of calcium carbonate to cigarette paper can enhance its combustion performance and apparent properties. However, it does come at the cost of reduced paper strength. In this study, a flexible calcium carbonate (FCC) was developed through the in-situ formation of calcium carbonate on nanocellulose surfaces. The incorporation of FCC into cigarette paper offered the potential to improve filler retention and combustion performance while maintaining high paper strength. The results of the study demonstrated that when compared to the addition of 30% precipitated calcium carbonate (PCC), the filler retention rate in cigarette paper increased by 31.5% when 30% FCC was used. Scanning electron microscopy images showed that only a minimal number of inorganic particles were observed between the fibers in the FCC-containing paper, indicating appropriate air permeability and fiber-fiber bond strength. Furthermore, when compared to PCC-containing paper, the FCC-containing paper exhibited an 8.8% increase in tensile strength and a 7.5% increase in folding resistance. Additionally, thermogravimetric analysis of the cigarette paper revealed that the incorporation of flexible calcium carbonate effectively lowered the thermal decomposition temperature, leading to a 10.3% increase in the combustion rate of FCC-containing paper. The inclusion of FCC into paper fibers has the potential to enhance air permeability and regulate cigarette burning performance. Consequently, the FCC developed in this study holds promise as a substitute for traditional calcium carbonate fillers in cigarette paper applications. [ABSTRACT FROM AUTHOR]

AbstractResearchers face the challenge of efficiently navigating vast scientific literature while valuing printed papers in the digital age. Printed materials facilitate deeper engagement and comprehension, leading to active reading engagement and enhanced retention. However, existing digital tools often need to pay more attention to the needs of researchers who value the tactile benefits of printed documents. In response to this gap, we introduce AR-PaperSync, a solution that leverages Augmented Reality (AR) and cross-device interaction technology. AR-PaperSync integrates the physical experience of printed papers with the interactive capabilities of digital tools. Researchers can navigate inline citations, manage saved references, and synchronize reading notes across mobile, desktop, and printed paper formats. Our user-centric approach, informed by in-depth interviews with six researchers, ensures that AR-PaperSync is tailored to its target users’ needs. A comprehensive user study involving 28 participants evaluated AR-PaperSync’s significantly enhanced efficiency, accuracy, and system usability and reduced cognitive load in academic reading tasks compared to conventional methods. These findings suggest that AR-PaperSync enhances the reading experience of printed scientific papers and provides a seamless integration of physical and digital reading environments for researchers.

The primary heat transfer source in the conventional multi-cylinder drying of paper and board is conduction. Conduction is facilitated by high-tension contact with steam-heated cylinders, while convective drying, the main mass transfer source, operates as heated air flows over the article web in the pockets. This conduction process occurs at elevated temperatures and contact pressures to ensure effective contact between the wet paper web and the heated cylinders. The contact pressures and temperatures of the hot surface significantly influence the conductive drying characteristics. This research paper presents an experimental study that involves designing a simple lab-scale setup with in-situ and continuous sensing capabilities for various commercially available grades of paper and board. Embedded thermocouples measure the temperatures of the heated platen and the sheet, allowing the collection of flux data to determine heat transfer characteristics. The goal of this study is to ascertain the instantaneous contact coefficients for different basis weights as a function of moisture content. The acquired data will provide valuable insights and information toward process development, design, and simulation of the article drying process. [ABSTRACT FROM AUTHOR]

Imidazo[1,2-a] pyridine-based two probes with different substituents containing oxime and hydroxyl functional groups were synthesised and evaluated for detection of tabun nerve agent simulant diethylcyanophosphonate (DCNP). The nucleophile hydroxyl group present on both the probes can be rapidly phosphorylated by DCNP through a nucleophilic substitution reaction. The probes were fluorescent and on reacting with DCNP underwent fluorescence OFF, which can be visualised under a UV lamp at 365 nm wavelength. The limit of detection for probes 1 and 2 was calculated as 0.66 μM and 0.54 μM, respectively. The mechanism of detection was studied using spectroscopic techniques revealed that the hydroxyl group is involved in the reaction with DCNP. The probes were found selective for the detection of DCNP in presence of other electrophilic interfering agents. Results were obtained in aqueous media and probes can be used directly for the rapid and sensitive detection of DCNP in water without any pretreatment. [ABSTRACT FROM AUTHOR]

In response to the COVID-19 pandemic, many nation-states adopted militarized measures for rapid containment. China notably implemented extreme and enduring war-like procedures. This study aims to explore the implications of securitizing the pandemic through a feminist lens and suggest ethical and equitable strategies for understanding emergencies and coping with future crises. Employing discourse-based online ethnography, it analyzes social dynamics in China’s “pandemic war,” examining how gender and (in)security are co-constructed and the role of feminist activism within an authoritarian context. This article argues that framing the pandemic as war reinforces a masculinist stance of dominance, prioritizing state stability over human rights and security. State-centric securitization perpetuates state authority, gendered social hierarchies, and structural violence. The exclusionary nature of this approach created new avenues for feminist activism, both online and offline, advocating for marginalized groups, raising social and gender awareness, challenging state narratives, and fostering collective resistance. Drawing lessons from Chinese feminist initiatives during COVID-19, this study calls for alternative crisis responses focused on care, equity, ethics, and collaboration. [ABSTRACT FROM AUTHOR]

The article discusses the concept of permeable boundaries in psychoanalysis, tracing its historical development from Freud's principles to the introduction of Self Psychology by Kohut. The authors explore the therapeutic benefits of more emotionally involved and humane therapist-patient relationships. Different perspectives are presented by discussants, including the importance of empathy, mutual influence, and the dialectic tension in relationships. The article also addresses concerns about boundaries, love, and the clinical application of permeable boundaries. [Extracted from the article]

The comment reviews the rigid rules of psychoanalytic technique established by Freud and their grip on practice in the Heroic Period of psychoanalysis, despite the irony that Freud himself broke his own rules with abandon. Heinz Kohut made the conceptual transformations in the theory by placing empathy at the center of the project. Richard Geist and Meredith Nocek creatively extend this tradition in their work "Permeable boundaries: Therapeutic benefits." [ABSTRACT FROM AUTHOR]

Edible polymers are safe for consumption by humans and use in society. Shellac is a derivative of Lac, which has been used for a long time in many different industries due to its remarkable properties, which include film-forming, water resistance, thermoplastic, adhering, bonding, and simple solubility in spirit and aqueous alkali solvents. A paradigm shift has been observed in the variety of applications and uses of shellac due to the growing desire for natural products, particularly in the food, pharmaceutical, 3D printing, stealth technology, green electronics, and intelligent sensor industries. It is commonly used as an enteric coating in the pharmaceutical sector and as a preservative coating or confectioners glaze in the food industry. Being a natural and eco-friendly substance, shellac has a great deal of potential for more sustainable technologies. Due to the film's strength and polymerization, shellac, however, has limitations. The low stability and mechanical brittleness of shellac, which result from self-polymerization reactions, limit its application even though it has great potential as an environmentally benign protective covering. This review offers a comprehensive understanding of lac, encompassing its characteristics, its uses, and its prospects for the future. This study aims to investigate a new method that may mitigate some of the disadvantages of shellac coating whilst improving the material's stability and mechanical properties. [ABSTRACT FROM AUTHOR]

Publishing scientific articles is an expedition of tenacious efforts with patience and conscientious decision-making; however, even with such careful consideration, researchers may overlook the dubious activities of clandestine organizations or remain oblivious to the unethical aspects of publishing. Paper mills are the latest impediment to academic publishing's integrity. The increasing number of paper mill publications damages the credibility of genuine journals and jeopardizes academic integrity, adding to the vulnerability of research. This paper deals with the tactics, activity, detection, impact, and solving the menace of such fraudulent practices. This paper is a summary of existing literature and analysis that aims to increase awareness of fraudulent practices like paper mills among researchers and academicians. [ABSTRACT FROM AUTHOR]

Cellulose was isolated from recycled pulp and paper sludge and used to synthesize cellulose nanocrystals. Response surface methodology and Box-Behnken design model were used to predict, improve, and optimize the cellulose isolation process. The optimal conditions were a reaction temperature of 87.5 °C, 180 min with 4% sodium hydroxide. SEM and TEM results revealed that the isolated cellulose had long rod-like structures of different dimensions than CNCs with short rod-like structures. The crystallinity index from XRD significantly increased from 41.33%, 63.7%, and 75.6% for Kimberly mill pulp sludge (KMRPPS), chemically purified cellulose and cellulose nanocrystals, respectively. The TGA/DTG analysis showed that the isolated cellulosic materials possessed higher thermal stability. FTIR analysis suggested that the chemical structures of cellulose and CNCs were modified by chemical treatment. The cellulose surface was highly hydrophilic compared to the CNCs based on the high water holding capacity of 65.31 ± 0.98% and 83.14 ± 1.22%, respectively. The synthesized cellulosic materials portrayed excellent properties for high-end industrial applications like biomedical engineering, advanced materials, nanotechnology, sustainable packaging, personal care products, environmental remediation, additive manufacturing, etc. [ABSTRACT FROM AUTHOR]

During the early Cold War, it was difficult for American intelligence to penetrate the Iron Curtain but a potential solution soon arose: émigré intelligence groups such as the Magyar Harcosok Bajtársi Közössége (MHBK) or 'Association of Hungarian Veterans'. This group, however, turned out to be an intelligence 'paper mill'. Attempts at trans-Atlantic cooperation with the MHBK and similar groups failed as they lost most of their good sources and were penetrated by communist security services. By the mid-1950s, US intelligence cut these groups off, took over their good sources, and established a source registry to prevent recurrence of the problem. [ABSTRACT FROM AUTHOR]

Thiophene sulfide is difficult to be removed by hydrodesulfurization. In this study, ZnCl2-waste paper fiber activated carbon was used as adsorbent to remove thiophene sulfide from simulated oil by hydrothermal modification. Under the optimum condition of ammonia modification, the adsorption capacity of modified adsorbent to BT is 14.8 mg S/g, 2.98 times that of unmodified. BET, FTIR and Boehm analysis showed that the mesopore volume of ammonia modified adsorbent increased by 96.62% and the mesopore ratio increased from 12.58% to 43.40%, which was conducive to improving the adsorption rate. After modification, the basic groups on the surface of the adsorbent increased by 44.3 times, and –NH3+, –OH and –NH2 enhanced the electron attraction and hydrogen bonding force between the adsorbent and BT molecule. Adsorption isotherms, adsorption kinetics and adsorption thermodynamics show that the adsorption process is spontaneous, entropic and exothermic. The pseudo-second-order kinetic rate constant increases with the increase of adsorption temperature, indicating that the increase of temperature is beneficial to accelerate the adsorption rate. The adsorption desulfurization process follows the mechanism of single and multilayer adsorption mixing. The results of this study can help to reveal more clearly that biobased activated carbon can be modified to adsorb thiophene sulfide. Ammonia modified adsorbents enhance the adsorption capacity for benzothiophene [ABSTRACT FROM AUTHOR]

Here, we propose a sensing scheme based on an all-dielectric metamaterial with the smooth reflection and transmission spectral lines in 10-60THz, and verify the applications of the measuring the resonance characteristics of Xuan paper samples. The reflection and thermal conductivity of Xuan paper samples enhance with the concentration of alum water increasing and weaken due to the thickness increasing. These results provide a solid foundation for this metamaterials in measuring the reflective and thermal resonance properties of Xuan paper samples. [ABSTRACT FROM AUTHOR]

Starch is one of the oldest adhesives, and has been utilised for a variety of applications, including as a consolidant for artworks and archives, after cooking. Although widely available, cost-effective, and versatile it has limitations such as large particle size, which makes it challenging for the adhesive to penetrate deeply into objects. Attempts to increase the concentration of starch adhesives for enhanced strength often lead to increased viscosity, hindering penetration and causing an undesirable film on the surface. Achieving a workable consistency often leads to reduced adhesive power. An approach to using nanosized starch as a binder for paper and cellulose-based objects is presented. Starch nanoparticles (SNPs) from wheat, rice, maize and waxy maize were successfully synthesised using a 'top-down' approach that is facile as well as energy efficient. Size distribution measurements indicate most particles to be less than 50 nm, smaller than the pore size of most historic papers. SNPs could make a better sizing adhesive than traditionally-made starch paste, and they are also a green alternative to a variety of chemically formulated, organic solvent-based adhesives. The compatibility, non-toxicity, and biodegradability of starch remained uncompromised during the modification. [ABSTRACT FROM AUTHOR]

Ink-paper historical documents, which are an important part of cultural heritage, can be damaged by various materials on the outside and the inside of the paper. Cotton fiber sheets treated with iron gall ink and then treated with stabilization materials were studied. Nanosized Mg(OH)2 was used as a deacidification material and potassium bromide, tetrabutylammonium bromide, or propyl gallate as antioxidant materials were investigated as a stabilization system for iron gall ink-damaged paper. All samples were artificially aged in the air for 150 h at 65 °C in a UV/moisture chamber or 500 h at 90 °C. The pH and alkaline reserve (AR) measurements, monitoring of color change, and scanning electron microscopy analysis data confirm that the aging effect is more destructive to the iron gall inked paper. The experiment results show that using alkaline materials with antioxidants, such as nano-Mg(OH)2 and propyl gallate, positively affects color changes of ink-damaged paper. Treatment with a stabilization system such as nanosized Mg(OH)2, a binder hydroxypropyl cellulose (Klucel), and an antioxidant as propyl gallate is a suitable method for iron gall ink damaged paper stabilization and preservation, according to the study results.

The present article provides a comprehensive analysis of the aging phenomenon of transformer insulation and the corresponding changes in insulation performance that occur over time. The present manuscript outlines diverse insulating materials that are employed in transformers, the fundamental aging mechanism of the insulation, the function of space charges in the aging of the insulation, and various simulation methodologies utilized for diagnosing the insulation status of the transformer. The primary focus of this paper is to examine the various numerical techniques employed in modeling and analyzing the aging characteristics of transformer insulation. The mechanisms underlying the accumulation of charge and distortion of electric fields in insulation are explained through the utilization of numerical modeling techniques. This paper focuses on understanding the mechanism of insulation aging, thereby facilitating the optimization and maintenance of insulation performance throughout its operational lifespan.

In a project to preserve photographic archives in Southeast Asia, the authors sought to develop sustainable solutions with low environmental impact, avoiding air conditioning and using locally available materials. Dry cabinets were tested and implemented to store a glass plate negative collection that was rehoused in envelopes and boxes made locally. The project took just over a year to complete, and two years of monitoring environmental conditions have shown that relative humidity can be stabilized at low levels. However, the dry cabinets are airtight to limit the introduction of moisture and dust, preventing air exchange. In order to avoid the build-up of degradation by-products released by the stored materials, and in particular off-gassing of acetic acid from the cellulose acetate-based photographs, the use of an adsorbent is necessary. To achieve this, a cellulose-based composite with particles of a porous hybrid inorganic/ organic solid, denoted as a metal–organic framework (MOF), at a very high loading over 70% by weight and shaped as a sheet of paper, has been prepared and tested. This special paper maintains acetic acid-free air in the cabinets and also helps to reduce the energy consumption by reducing the need for cool storage. This MOF paper composite traps small carboxylic acids and was found to be an appropriate solution for maintaining clean air in the dry cabinets or any other confined space or enclosure. Additionally, it can also be designed to trap other noxious pollutants such as hydrogen sulfide or formaldehyde, by choosing other MOFs. [ABSTRACT FROM AUTHOR]

The 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.

Scientific papers and patents are reliable sources of knowledge carriers for measuring science and technology advances, predicting technological trends, and formulating technology strategies. Although the idea of entirely using the two knowledge carriers is rapidly emerging in academic discussion, a theoretical framing of the comparisons is still not present in literature. This study conducts bibliometrics on 2986 patent families and 4755 scientific papers related to silicon carbide metal–oxide-semiconductor field-effect transistor (SiC-MOSFET) to identify its technological trends and compare the similarities and differences in knowledge generation and diffusion in science and technology. Our methodological framework consists of a combination of geographic distribution (identifying the research developments and distribution), cooperation networks (analyzing organisation collaboration and individual research cooperation), noun phrase co-occurrence clusters (discovering hot research topics), and the global main path analyses of citation networks (tracking the trajectory of knowledge flows). Ultimately, our results contribute to recent bibliometric paradigms beyond discovering the role of scientific papers and patents in promoting science and technology integration.

This discussion of two related papers on political activism by Bettina von Lieres and Afarin Kohan focuses on the mechanism of transformation from psychic experience into political action. In both papers, the move to political action is seen as a consequence of collectivization, politics being understood as a function of groups, but a distinction is made between brute politics and the elaboration of the political as a psychoanalytic process. The original papers are seen as furthering the aims of social psychoanalysis and community psychoanalysis. [ABSTRACT FROM AUTHOR]

This paper/visual art/puppet show is about the more-than-human entities who help me include my whole self in my teaching and other research. It is about how generative it is to be our whole, sacred, profane, glorious selves. This art reminds us of the importance of dreaming beyond what we have been told is possible. It demonstrates how irreverent, gleeful, binary-challenging art makes oppression more visible, so that we can challenge it. This work is about interrupting hegemony/the status quo/the idea that some of us are ‘normal’ and the rest should be pecked to death. It is about resistance strategies for poking fun at power, especially our own (so we don’t become someone who attacks difference). The puppet collaboration aspect came from shared frustration with the Non-Profit Industrial Complex. This collaboration is part of our ongoing, decades-long experimentation. This paper includes art that I shared as a participant in dichotomy-challenging research, which uplifted the voices of Mad social workers. This art makes fun of my profession of social work. I was encouraged to have space to express my feelings, without being constrained by mere words. I invite you to share the dream of being our whole selves, beyond and within the confines of universities, professions, classrooms, societies and research. By continuing to play in unsafe circumstances, I am keeping myself, connection, dreaming beyond binary, and art as resistance. What are you fighting for? How are you making fun of yourself?

The use of the arts in social work is creating space to reimagine effective communication, meaningful relationships and social change. Peripheral to this growing body of knowledge is jewellery design and making, a lacuna that this paper addresses within the context of recovery journeys. The paper presents art as an activity which can lead to tangible outputs, understood as ‘boundary objects’ and as an embodied aesthetic and sensory experience, for building dialogical relationships. Using the concept of ‘boundary objects’ is a new, yet achievable ambition for social work. Insights are presented from a small qualitative study on the use of jewellery making for assisting women, who have experienced trauma, to develop a positive self-identity and confidence. Jewellery making is introduced as a method for reframing trauma narratives into tangible objects. Part of the women’s embodied experiences are situated in the jewellery, an object of adornment external to them, rather than remaining trapped inside their body. For social workers, identifying objects (a piece of jewellery, a photograph, or any range of items) that symbolises or contains meaning for service users, can unlock a conversation that can lead to a deeper understanding of the person, their past, present and future ambitions.

The pulp and paper industry stands out as an example of a technology based on a renewable resource, cellulose. The sludge, however, poses major environmental and public health problems. To effectively manage the sludge wastes, it is critical to fully evaluate its composition, possible environmental impacts, and the total amount of exploitable renewable resources. The study established the pH of the sludge to be 7.32 ± 0.98, an electrical conductivity (1.84 mS/cm), nitrogen concentration (2.65 ± 0.21%), and total organic matter (41.23 ± 3.11%). The cellulosic content was established to be 74.07 ± 2.71% which contributes to 53.07 ± 1.23% water holding capacity (WHC). The most abundant elements were C and O, followed by Cl, Si, Al, and Mg, with lower concentrations of S, Si, K, and iron. The polycyclic aromatic compounds (PAHs) levels ranged from 0.29 to 322.56 ng.g-1 with 1-methyl pyrene posting the highest concentration (322.56 ng.g-1. XRD peaks at 17.10°, 23.86°, 30.14°, and 36.57°, which imply the existence of CaCO3. SEM indicated that the sludge was majorly comprised of fibers materials with average particle sizes of 280 micrometers. TGA/DTG analysis showed that the sludge had the greatest cellulose and hemicellulose (64.7 wt. %). [ABSTRACT FROM AUTHOR]

Per- and polyfluoroalkyl substances (PFAS) analysis has become crucial due to their presence in the environment, their persistence and potential health risks. These compounds are commonly used in food contact materials (FCM) as a coating to provide water and grease-repellent properties. One of the pathways for PFAS to enter the human body is either through direct consumption of contaminated food or indirectly through migration from FCM into food. The purpose of this study was to investigate where the initial contamination of paper FCM occurs. We analysed paper material consisting of fresh fibre and secondary materials, intended to produce food packaging for the presence of PFAS. The samples were extracted and analysed for 23 different PFAS substances using the targeted approach with LC tandem mass spectrometry (LC-MS/MS). This analytical technique detects specific, easily ionisable PFAS with high sensitivity. However, one drawback of this approach is that it allows the identification of less than 1% of the PFAS known today. For this reason, we used combustion ion chromatography (CIC) to determine the content of extractable organic fluorine compounds (EOF) and compare it to the total fluorine content. The targeted analysis using LC-MS/MS measured an average sum concentration of PFAS of 0.17 ng g−1 sample. Our research shows that the primary PFAS contamination happens during the recycling process since all of the samples in which the targeted PFAS were measured belonged to the secondary material. The most frequently detected analytes were PFOA and PFOS, detected in 90% and 62% of the samples, respectively, followed by PFBS (in 29% of the samples). CIC showed that measured PFAS via LC-MS/MS amount to an average of 2.7 × 10−4% of total fluorine content, whereas the EOF was under the LOD in all of the measured samples. This result highlights the complexity of the accurate determination of PFAS compounds, displaying what kind of information the chosen methods provide. [ABSTRACT FROM AUTHOR]
