INFORMATION sharing , *CULTURE - Abstract
Since the 1970s, a continuous exchange of information about conservation between Europe and East Asia has greatly influenced approaches to the treatment of paper objects as well as the tools and materials used. This knowledge is often disseminated and absorbed in a purely practical manner, stripped out of its wider cultural context. However, what is considered 'appropriate' treatment is closely linked to how a particular culture has historically interacted with artworks and arguably the lack of broader cultural perspectives can lead to misguided assumptions in the evaluation of those practices. This article reflects on the differences between European and East Asian cultures of paper conservation. By taking into consideration the relevant cultural, philosophical and historical contexts, the article aims to explore how approaches to conservation, as well as to the profession itself, have developed in these two different parts of the world. It further encourages paper conservators to reflect on their own training and practices while offering an understanding of how these approaches can sometimes be mutually exclusive.

Modeling of the dryer section of a paper machine is of high importance in both designing and operation points of view. In this research, a novel thermodynamic and heat and mass transfer model has been introduced. The model is based on empirical equations of the literature and does not need fine discretization techniques such as finite difference method. The method used for calculation of convective heat and mass transfer coefficients of the dryer is a modification of the methods utilized in the literature. The trend of paper and air temperature in the dryer, the steam consumption of each cylinder, as well as the trend of drying process throughout the dryer has been calculated. Overall results of the dryer such as the total evaporated water and the specific steam consumption of the dryer have been obtained too. The results have been validated with experimental data of a previous research in the literature and show a relatively good agreement with the experimental data. Finally, the sensitivity of the results to some main parameters has been analyzed. [ABSTRACT FROM AUTHOR]

With the increasing importance of wood as a sustainable material and addressing challenges facing the wood products industry, there is an emerging need for innovation and collaboration across all industry sectors. The mapping of the wood products industry has become crucial for gaining an overview and overall understanding of material flow. It also proved beneficial for educational and research purposes. The outcome of this study should help seek new economic opportunities and promote sustainable resource management. A Generic Map was developed to navigate the entire wood products industry as well as Dive-in Chain Maps will guide the four major production chains: sawmill (I), veneer mill (II), reconstituted wood manufacturing (III), and pulp and paper mills (IV). In addition, a By-products Management Wheel Diagram was introduced to clarify waste management practices within these chains. Our approach sheds light on efficient material flow and utilization, revealing opportunities for innovation and the development of high-value products. It also offers strategies for minimizing waste and making informed end-of-life decisions. Ultimately, this study enhances the understanding and potential for circularity and sustainability in the wood products industry. [ABSTRACT FROM AUTHOR]

DIGITAL transformation ,BUSINESSPEOPLE ,SOCIAL capital ,FINANCIAL performance ,ELECTRONIC paper - Abstract
Current research on the relationship between digital transformation and financial performance (FP) remains inconclusive. This paper conceptualizes digital transformation as technology-based digital transformation (TDT) and market-based digital transformation (MDT), and explores their heterogeneous impacts on FP. It is further assessed how such distinctive effects are moderated by three types of entrepreneurs' social capital, i.e. entrepreneurs' technological social capital (ETSC), entrepreneurs' business social capital (EBSC), and entrepreneurs' institutional social capital (EISC). Using a carefully assembled dataset containing the relevant information of 2363 listed Chinese manufacturing firms covering the period of 2008–2018, these relationships are empirically examined, and the following is found: (1) TDT positively affects FP; (2) MDT has a time-lagged positive effect on FP; (3) ETSC positively moderates the relationship between MDT and FP; (4) EBSC positively moderates the impacts of TDT and MDT on FP. These findings enrich the understanding of the concept and application of digital transformation. [ABSTRACT FROM AUTHOR]

SDN architectures are frequently used by organizations for the management of their networks and the detection of anomalous traffic in a single domain. However, in the real world, anomalous traffic might result in attacks like distributed denial of service (DDoS) that affect numerous domains. During intrusion detection, each SDN domain has to send real traffic data of a large volume to the multi-domain controller, exposing its sensitive information. This paper proposes a smart multistage framework for detecting attacks and ensuring privacy at no additional cost. This work utilized the recent unbalanced InSDN dataset for experimentation. It also uses an oversampling technique that reduces the imbalance rate for each attack type and selects the smallest possible training size and feature set size for an increase in detection accuracy and a reduction in computational complexity. Then, a multi-class classifier method for intrusion detection that does not require regularization or hyperparameter tuning, called ensemble-learning-based shallow decision tree (ELSDT) is proposed. Furthermore, the performance of the proposed classifier on the InSDN dataset is assessed on an SDN testbed. Experimental results show the ability of the proposed smart multistage privacy-preserving framework to make a significant reduction in the training sample size and feature set size to 87% and 76%, respectively. It also shows its outperformance in recent literature works by 5.67% improved accuracy. [ABSTRACT FROM AUTHOR]

This study analyzes the production of knowledge in the field of eco-innovation, checking its state of the art in order to discuss topics of future research. Specifically, it assesses the pulp, paper, and paper products industry in Brazil in order to examine the drivers of the adoption of eco-innovation strategies. The study is essentially a review of the literature, with a methodology based on exploratory research, and using the documental and bibliographical qualitative method. The empirical research was based on a quantitative approach using the strategy of a cross-sectional survey by means of a self-administered online questionnaire. It was verified that the studies related to eco-innovation are still preliminary and that the subject lacks specific research with empirical data from survey and in-depth case studies. The following topics were checked for studies on innovation in environmental issues on conceptual and theoretical discussion; models and indicators for evaluating the eco-innovation; types; and political arguments for their development, with the proposition of research lines within this context. The results of the empirical research allow us to conclude that factors such as environmental regulation, the use of environmental incentives and innovation, reputation effects, top management support, technological expertise, and environmental formalization in the context of domestic enterprises are crucial to the adoption of eco-innovation. Further, the higher the extent to which companies embrace an environmental and innovative culture, the greater the internalization of eco-innovative practices. [ABSTRACT FROM PUBLISHER]

The existing waste paper recycling technologies are based on partial incorporation of recycled cellulose fibers into “new” paper products. The main usage is in low-grade products, such as paperboards or wrapping papers. However, due to electronization of mass media in combination with increasing quantities of leaflets and continuous downward pressures on paper production costs, the waste paper currently used in the recycling scheme is of lower quality than paper used decades ago. It contains much more fillers, adhesives, dyes, polishers, and similar additives that are problematic for conventional paper recycling technologies. A sharp growth of this trend encourages conceptual reengineering of the existing technological processes in waste paper management. A techno-economic analysis of energy utilization by means combustion, anaerobic fermentation (also accelerated by steam-explosion), and pyrolysis was carried out in a pilot scale. The results have revealed that if the current trend continues, it might be reasonable to divert waste paper from returning back into production (recycling) and to prefer its commercial pyrolysis.

The pulp and paper sector is the fourth largest industrial sector in terms of energy use in the world. Of the numerous processes involved in paper-making by a paper machine, the dryer section is the process that consumes the largest amount of energy. A model-based method for estimating energy-saving potentials of the dryer section was put forward in the present study. It was done by four steps: establishing a mathematical model about energy consumption, determining the model parameters, benchmarking the drying performance to obtain the corresponding energy-saving measures, and estimating the energy-saving potentials by using the mathematical model. In a case study, a multi-cylinder dryer section was selected to illustrate the method. After a fundamental field test and observation, several operating problems that restricted the energy performance of paper drying were found. And then several reasonable energy-saving measures were suggested to the operators. Finally, applying the mathematic model, it was found that 0.32 ton of steam will be saved when producing 1 ton of paper in recommended operating conditions. With the designed capacity of 200,000 tons/year, the annual steam-savings will be 64,000 tons. Generally, the price of steam is 130–150 Chinese Yuan (about US$21–24) in China, and the annual economic benefits will be 8.32–9.60 million Chinese Yuan (about US$1.344–1.536 million).

In this work, a hierarchical Al2O3carbon fiber (H-Al-CF) was successfully fabricated for application in the removal of iodide ions from water. High yields of Al2O3-coated carbon fiber were prepared by a sol–gel process using waste paper fibers as templates and carbon sources. The H-Al-CF is fabricated by an in-situ growth of AlOOH nanocrystals on the surface of carbon fibers following calcination. The synthesized H-Al-CF exhibits the developed porosity including mesopores and macropores, and has high-specific surface area (348.9 m2 g−1) and iodide ions' adsorption efficiency (92.3%). The in-situ growth process ensures that H-Al-CF has a more stable structure, further promoting higher adsorption efficiency. [ABSTRACT FROM PUBLISHER]

The international recovered paper trade serves two important functions: increasing raw material availability in the paper and board industry and providing economic incentives to recycle. The purpose of this paper is to shed further light on emerging patterns in this trade by empirically analysing the changes in the bilateral trade flows of recycled paper between 1992 and 2008. According to our estimations, two important changes occurred in the 1990s and 2000s. First, the growing importance of developing economies in global recycled paper trade plays a significant role in import demand as a determinant of trade flows. Second, the changes in global trade patterns necessitate investigating the transportation cost measures used in applied research. [ABSTRACT FROM AUTHOR]

Brittleness, discolouration, translucency, and solvent sensitivity are a few of the factors that need consideration when conserving transparent papers. These considerations coupled with the large format and the volume of transparent papers in collections makes effective preservation planning difficult. To address this problem a project was initiated to improve the standard of preservation for transparent papers in The National Archives’ collections. The significant outcomes of this one year project were a framework for preservation decision-making, and complementary tools designed to gather information to support better planning and treatment. The tools include survey questionnaires, a condition rating scale, a colour rating scale, and a database to capture information about the condition and types of transparent papers held by The National Archives.

The need for good quality paper for dye sublimation transfer printing has been reported previously as a principal requirement for the process. Pigmented coated papers have gained acceptance in the traditional paper printing industry, but, despite their importance, have inspired very few reports in literature about their application in heat transfer printing. In the current work, we studied the influence of both clay and ground calcium carbonate (GCC) pigments and the incorporation of plastic pigment on the surface structure and mechanical properties of the coated paper used for transfer printing. The results showed that paper coating significantly reduced the surface roughness of the paper. The mechanical properties of the prepared coated paper, including tensile strength, stretch, tensile energy absorption (TEA), and burst index, were improved when coated compared to those of uncoated paper. The addition of plastic pigment to the coating mixture helped improve the paper's properties. The optical density of the transfer-printed polyester fabric using the prepared coated paper was also compared with that of uncoated paper. It was shown that a slight increase in optical density was evident in the coated paper. The possibility of producing a second polyester print from the exhaust paper was also investigated. Coated paper incorporating plastic pigment, in particular, showed higher optical density than did uncoated paper. We found that coated paper based on clay, GCC, clay/plastic pigment, or GCC/plastic pigment consumed less dye paste than uncoated paper though producing printed fabric with higher optical density - especially in the second print.

Most of the micromineral inclusions generated by the RMR process in Schickler apatite appear to be REE minerals; an example EDS spectrum of a typical REE inclusion is shown in figure 2. The I T i I O i I T i modules within these minerals can be used to derive many mineral properties by first principles, e.g., habit, cleavage angles, and symmetry/polytypism (fig. 1). Among other minerals, striking red-brown apatite crystals, to 10+ cm, can be found hosted within the dissociated calcite-fluorite carbonatite matrix. However, the diversity of these modular rock-forming minerals results in complexity in terms of the crystal structures and crystal chemistries of this mineral family. [Extracted from the article]

Doreen Massey's academic repertoire, as a human geographer and political thinker, is almost unmatched. This review essay catalogues my experience of 'meeting' Massey through the eyes of David Featherstone and Diarmaid Kelliher, the editors of this collection of selected political writings. Highlighting Massey's contributions to theories of relationality, space, place, politics and praxis, I show how the collection captures her ability to synthesise everyday struggles and global political-economic processes. We also meet Massey in her various, intersecting guises: academic, political organiser, person. Where the book brings forth a vision of Massey as scholar and as public intellectual, I further comment on how her contributions are framed within geography and particularly her influence on feminist geographies.

In 2015, the Open Science Collaboration reported in the journal Science that a disturbingly large proportion of psychological studies cannot be replicated (Open Science Collaboration, 2015). The ensuing 'reproducibility crisis' became a lightning rod for contesting what counts as legitimate research, and for negotiating the relationship between communication infrastructures and research practice. In the psychological and cognitive sciences, the Open Science community has advocated widespread reforms to incentivize transparency, encourage replication, and detect and discourage questionable research practices. The model of 'openness' underlying mainstream Open Science centers on sharing information to increase science's self-correcting capacity. Against the backdrop of broad-scale transformations in Open Science, this case study depicts how scientists read. By examining the activity of a group of researchers 'virtually witnessing' an experiment together, this study reveals reading as a non-trivial process that matters for how research is apprehended and for how science is moved through time and space. The case complicates a disembodied, information-centric 'openness' pursued by mainstream Open Science reforms and advocates integrating situated and embodied resources into methods reforms, beginning with practices of reading.

In this study, we have developed a self-standing nanocomposite mat, which combined of copper (benzene 1,3,5-tricarboxylic acid) MOFs (Cu(BTC)MOFs) and carbon nanofibers (CNFs) and used as an enzyme-free electrochemical sensor for detection of 4-nitrophenol in phosphate buffer (pH = 7). The high specific surface area and variety of functional active adsorption sites of as-developed hybrid mat facilitated faster transport of analyte molecules across the electrode-electrolyte interface. The Cu(BTC)MOF@CNF-modified glassy carbon electrode (Cu(BTC)MOF@CNF/GCE) demonstrated improved electrocatalytic responses toward 4-nitrophenol. The as-developed electrode showed that an excellent sensitivity (2.3429 μA μM−1 cm−2) with good selectivity and outstanding cyclic stability. The hybrid sensor exhibited a widespread linear range from 5.0 to 400 µM along with a low detection limit of 87.12 nM, for 4-nitrophenol determination. The present sensor electrode showed anti-interference property and high selectivity with good storage stability up to 30 days. Lastly, the sensing performances of the Cu(BTC)MOF@CNF/GCE toward para-nitrophenol in real samples give the satisfactory results, which proved the practical applicability of the present hybrid material. Furthermore, the real sample analyses results validated through HPLC results, and it was observed that the current results are in comparable with high-performance liquid chromatography data.

In 2011, the Taiwanese Ministry of Education issued a policy on the internationalisation of schooling. The policy assumes that being 'international' has become necessary in order to maintain economic competitiveness in a globalising world. It was published in two languages: Mandarin, the official language in Taiwan, and English, presupposed as a lingua franca. Treating 'policy as discourse', the article analyses internationalism and its performativity through the publication and specific textual construction of this policy. The analysis considers the layout, target readerships, conceptual translation, and spatial representation and construction of 'Chineseness' in the two policy texts. This attempt at internationalisation is related to the very specific historical and geopolitical conditions of Taiwan and its liminal position in the globe. The significance of the article rests in expanding ideas of 'translation' in education policy studies and in the analysis of the specific geopolitics of East Asia. [ABSTRACT FROM AUTHOR]

The confluence of the two major challenges has combined to create special challenges for rural nonprofits serving victims of crime: the fluctuation of federal funding, and the Covid-19 pandemic. We discuss the challenges faced by Child Advocacy Centers in northwestern South Carolina in the context of these shifting challenges. From qualitative interviews conducted at 14 centers in this primarily rural region, we explain the challenges they face and the potential effects on the communities they serve interpreted through the lens of Resource Dependence Theory, which predicts that organizations reduce uncertainty of funding through increasing their partnership bonds with cooperative entities.

SUPERVISORS , *BANKING industry , *MONETARY policy - Abstract
After over a decade of crisis, the ECB's functions have expanded considerably, which in turn altered its relationship with other institutions. In particular, when the ECB assumed the role of Banking Supervisor under the Single Supervisory Mechanisms, it was generally accepted that this role would require more accountability than its traditional role in monetary policy. Yet, accountability requires transparency. However, there is a dearth of studies on the transparency of European banking supervision, and the few that exist are usually single case studies. This leaves us without a point of comparison that would help us understand what constitutes a 'transparent banking supervisor'. Therefore, the aim of this article is to situate the transparency of the ECB within the wider literature on the transparency of banking supervisors. This allows us to pinpoint more precisely its strengths and shortcomings and the potential for reforms. [ABSTRACT FROM AUTHOR]

Barrett, Thomas F.
- Abstract
Psychoanalysts have increasingly sought opportunities to move beyond their consultation rooms to find ways to provide service from a psychoanalytic point of view where it could be well utilized. While there is a long tradition of these endeavors, such as Freud's free clinics, for child analysts searching for ways to provide service and support for young children and for those who care for them has long been an ideal.

This study aims to validate a data collection tool's psychometric properties to explore whether business management research's relevance is a high-order construct made up of its perceived interest and perceived relevance. The authors conducted a confirmatory factor analysis to validate a two-factor scale. The sample was composed of 148 MBA students from a Peruvian business school. Results showed the appropriate levels of validity and reliability and confirmed the usefulness of this data set for exploring the relationship between perceived interest and relevance. Businesses and schools can replicate the validated tool for reviewing their curricula and teaching practices, exploring the gap between business and management research results and advancing managers' research literacy and evidence-based practice in business education and training.

To further enhance the performance of nano-silica modified M-phenylene isophthalamide (MPIA) insulation paper, nano-SiO2 particles are modified by 3-aminopropyltriethyloxy silane (APTS) surface into meta-aramid insulation paper to form grafting nano-silica particles (GNP). In order to find the relative best performance of the nanoparticle doping ratio, molecular dynamics simulations were used to study the effect of different GNP volume fractions on the mechanical parameters of the MPIA amorphous region, and the highest mechanical performance was obtained with a volume fraction of 9.4 vol. %. Under this doping condition, the interaction between GNP and MPIA fibers was enhanced by the formation of a large number of hydrogen bonds. The addition of GNP decreased the diffusion of water, acid and gas in MPIA fibers and the influence of these substances on the thermal stability of aramid fibers. All these indicate that the addition of GNP further improves the performance of aramid insulation paper, improves the thermal stability of aramid insulation paper and delays the aging process of oil-immersed aramid insulation paper. This article provides a reference and basis for the preparation of meta-aramid insulation paper with relatively good thermal stability. [ABSTRACT FROM AUTHOR]

Clear legal content of white papers provides certainty, stability and trust in the relations between all the participants in initial coins offering (ICO) procedures and contributes to the successful introduction of blockchain technologies in business. A white paper defines the relationship and interaction between a regulated social reality and program code, which is by itself not susceptible to legal regulation. This article investigates the legal conditions of the white papers that describe the projects of ICO. The author provides a legal analysis of numerous white papers published during ICO implementation around the world. Based on extensive data on implemented ICO projects, the correlation between the legal content of a white paper and the amount of funds collected as a result of the ICO is considered. Having analysed the determinants of the white paper legal content, the author suggests the legal provisions that any ICO white paper should have. [ABSTRACT FROM AUTHOR]

A two-step process involving coagulation-flocculation followed by solar photocatalysis – based Advanced Oxidation Process (AOP) using TiO
2 -Reduced Graphene Oxide (TRGO) nanocomposite as catalyst has been employed for the treatment of pulp and paper mill effluent. As the effluent is loaded with a high amount of organics with initial chemical oxygen demand (COD) as high as 3516, a pre-treatment is required before applying photocatalytic treatment. Coagulation-flocculation was identified as an effective pre-treatment strategy. Among the various coagulants tested, CuSO4 .5H2 O showed the best % COD reduction of 84 at pH 6, at a loading of 5 g/L. The primary treatment of coagulation improved the biodegradability index from 0.23 to 0.37. TRGO photocatalyst, employed in the second stage of photocatalytic treatment was synthesised by an ultrasound assisted solvothermal method and well characterised by various spectroscopic/analytical tools. The composite was found to be an efficient solar photocatalyst and achieved 1.76 and 2.1 times more COD reduction than synthesised TiO2 and commercial P25 respectively. The final effluent after the combined treatment was neutral and the biochemical oxygen demand (BOD) and COD were 11.7 and 120 mg/L respectively which were below the given limit of National Environmental Quality Standards.

The controversy over vaccines, which has recently intensified following the COVID-19 pandemic, provokes heated debates, with both advocates and opponents raising allegations of bias and fraud in research. Researchers whose work raises doubts about the safety of certain vaccines claim to be victims of discriminatory treatment aimed at suppressing dissent, including the unjustified retraction of their published research. Such practices have previously been discussed in other controversial fields in science (e.g., AIDS, the environment, and water fluoridation) but not in the field of vaccines. The purpose of this study was to analyze, for the first time, the subjective views of researchers whose papers were retracted. Study participants are active researchers, most with international reputations in their respective fields. They perceived retraction as a means of censoring and silencing critical voices with the aim of preserving the pro-vaccination agenda of interested parties. Participants also reported additional measures aimed at harming them personally and professionally. These findings point to the need for a fair, open, and honest discourse about the safety of vaccines for the benefit of public health and the restoration of trust in science and medicine.

KINSHIP , *RIGHT of asylum , *CITIZENSHIP , *SYRIAN refugees - Abstract
Seemingly mundane bureaucratic papers – such as birth and marriage certificates – are official proof of legal identities and relations to kin, usually issued by the state of origin. For Syrians who have sought asylum in Germany, these documents are necessary during the asylum procedure and beyond, for certain bureaucratic procedures and the recording of crucial life events. Retracing the crafting of these documents in Syria, and their encounter with German bureaucracy, captures the depth of the entanglement between the Syrian and German citizenship regimes, as well as their discrepancies in relation to paperwork and legality. Drawing on ethnographic research with Syrians in Lebanon and in Germany, this article argues that the legal production of legality in Germany can only be achieved through legally ambiguous, if not so-called illegal, practices in Syria.

RETIREMENT - Abstract
In my discussion of Picard's paper, I emphasize how she does not explain or justify her unilateral decision to close her practice but instead offers us a more direct access to her experience, with sensitivity to her patients' pain, her own conflicts and personal needs. I believe Picard's choice to be candid rather than explanatory provides the reader with a far stronger message about retiring a clinical practice. I suggest that the interests beyond analytic practice that both beckon her and sustain her into retirement relate to my concept of an essential "nonanalytic third." [ABSTRACT FROM AUTHOR]

This work aims to explore the potentialities of an end-user personalisation platform in industrial settings. In such a context, stakeholders with different roles and competencies collaborate to manage and control an environment where legacy machines coexist and interact with newer ones. Our goal is to provide a rule-based tool that allows end-users to build personalised solutions to respond quickly to the dynamic needs of factories. We report on a case study in the paper factory domain, in which the industrial aspects identified with expert stakeholders through interviews have been simulated and addressed through an extension of a personalisation platform. A first user test of the resulting environment has been carried out with a representative set of users, and has provided useful and encouraging feedback in terms of the potentialities of the proposed approach in industrial contexts.

This project, entitledOut of the Frame: Flight by Paper Plane, explores ways of utilising origami, and especially paper planes, to generate creative patterns in fashion design. It also explores ways in which paper plane crafts, as a mode of thinking, can be incorporated into ‘practice-led’ design research. Employing the practice-led research methods defined by Niedderer and Roworth-Stokes [(2007, November).The role and use of creative practice in research and its contribution to knowledge. Paper presented at the meeting of IASDR International Conference, Hong Kong Polytechnic University], this paper uses the following research process: 1. Practice as posing research problems: out of the frame: flight by paper plane; 2. practice as context: origami and fashion design; 3. practice as a method of investigation: paper plane practice-led design methodology; 4. practice as a means of generating research outcomes: project evaluation and reflection. Throughout the practice-led design process, origami structures of paper planes serve as a valuable medium for exploring illimitable structures for further application and involve the designer in a complex problem-solving process through which optimal structures are developed.

This paper quantitatively investigates the compositions of the gaseous pollutants in the ambient air of a secondary fiber paper mill. Total volatile organic compounds (TVOC), formaldehyde (HCHO), sulfur compounds (H2S), and hydrocarbon compounds (CxHy) were analyzed on six sampling sites with photo-ionisation detector, acetylacetone spectrophotometric method, and gas detector. The results revealed that, the high levels of TVOC and CxHywere detected at the wet end of paper machine and the office area, respectively; all the H2S contents on the six sites exceeded the limit (0.06 mg m−3) seriously; the HCHO concentrations at other five sites were out of the limit (0.10 mg m−3) except for the wastewater treatment plant. Furthermore, the necessary discussions about the possible pollution sources were considered on the process flow, the chemical agents used, and the ambient conditions in the paper mill. For the sake of air pollution control in paper mills, these remarkable results and analysis lay some technical basis in the following researches that should attract more attentions.

The sorption capacity of a substrate serving as sampling medium can be enhanced by adding another sorbent to its surface. This is usually achieved through an impregnation process by repeated dipping of the substrate in a slurry solution containing the powder of the sorbent. Because the impregnation process only deposits the sorbent powder on the surface of the substrate, the powder could detach and fall off during field deployment. In this study, a novel approach was explored to fix the added sorbent powder to the surface of the substrate. Methylcellulose (MC) in fine crystal form was selected as the fixing agent to secure the powder of polystyrene-divinyl benzene copolymer resin (XAD-4), with its high sorption capacity, to a cellulose filter paper (CFP). The process involved first mixing XAD-4 and MC in the presence of water to form a milky slurry solution that was then painted on to the surface of the paper and then allowed to dry. The painting technique resulted in a good reproducibility of the applied amount of XAD-MC mixture with a relative standard deviation (RSD) of 12% (n = 5). Scanning electron microscope (SEM) images showed that the XAD-4 powder was held to the surface of the filter paper. No free XAD powder was dislodged from the coated filter paper when coated paper was flicked with a finger. For use as an indoor passive air sampler (PAS), this new sampling medium was placed in a round housing made of electronically polished aluminium material and was tested for uptake of polybrominated diphenyl ethers and phthalic acid dialkylesters. Surface area specific uptake rates (ASUR) of PBDEs ranged from 1.14 to 2.82 m3/(dm2d), while ASUR of phthalates had a wider range from 2.74 to 5.66 m3/(dm2d). [ABSTRACT FROM PUBLISHER]

A novel methodology was used to create a highly porous foam-formed paper that is bonded with highly refined cellulose fiber. In this process, cellulose pulp suspension at various consistencies (0.5, 1.0, 1.5, and 2%) was dispersed in water, followed by foam formation under high shear forces in the presence of a surfactant. Various drying methods were used to achieve foam formation. These included freeze-drying (FD), vacuum-dewatered air-drying (VAD), and dewatered freeze-drying (VFD). Increasing the pulp's consistency and changing the drying techniques from freeze-drying to air-drying resulted in a more compact morphological structure and increased density of foam-formed paper samples. Densification of foam-formed samples was measured using a Dynamic Mechanical Analysis (DMA) machine and a sample with densification at lowest strain value was obtained by a 10 wt% addition of microfibrillated cellulose fiber (MFC). At 10 wt% MFC addition, denser foam-formed paper samples with enhanced microstructure were obtained. Air filtration efficiency and acoustic properties of foam-formed paper were also characterized and optimized by the addition of MFC. [ABSTRACT FROM AUTHOR]

- Abstract
The release of RNA-containing extracellular vesicles (EV) into the extracellular milieu has been demonstrated in a multitude of different in vitro cell systems and in a variety of body fluids. RNA-containing EV are in the limelight for their capacity to communicate genetically encoded messages to other cells, their suitability as candidate biomarkers for diseases, and their use as therapeutic agents. Although EV-RNA has attracted enormous interest from basic researchers, clinicians, and industry, we currently have limited knowledge on which mechanisms drive and regulate RNA incorporation into EV and on how RNA-encoded messages affect signalling processes in EV-targeted cells. Moreover, EV-RNA research faces various technical challenges, such as standardisation of EV isolation methods, optimisation of methodologies to isolate and characterise minute quantities of RNA found in EV, and development of approaches to demonstrate functional transfer of EV-RNA in vivo. These topics were discussed at the 2015 EV-RNA workshop of the International Society for Extracellular Vesicles. This position paper was written by the participants of the workshop not only to give an overview of the current state of knowledge in the field, but also to clarify that our incomplete knowledge - of the nature of EV(-RNA)s and of how to effectively and reliably study them - currently prohibits the implementation of gold standards in EV-RNA research. In addition, this paper creates awareness of possibilities and limitations of currently used strategies to investigate EV-RNA and calls for caution in interpretation of the obtained data.

The printing press helped to spread literacy, civic discourse, and even political dissent in colonial America. Without paper, however, the invention of the moveable type printing press would have been insignificant. This crucial communication medium was hobbled by a critical shortage of the raw material needed for printed matter. Paper was in short supply in the colonies and in the new nation as it could only be made from rags, and there was constant difficulty in obtaining enough rags to keep the presses rolling. Pleas for this essential ingredient were constantly seen in the newspapers in early America and there were severe shortages of both paper and the rags from which it was made during the American Revolution. This article examines how desperate were the early Americans for the paper which was necessary both for firing the muskets and for spreading the rhetoric of Revolution. [ABSTRACT FROM PUBLISHER]

Drying of sewage sludge is typically modeled as simultaneous heat and mass transfer phenomena. The capability of conventional models to take into account crust formation, cracks, and shrinking is limited. Artificial neural networks (ANNs) are suitable tools for dynamic representation of drying processes; however, obtaining a suitable database is a resource consuming task. Based on the Taguchi method, nine experiments were defined to set up a training database and to develop an ANN model. A high Pearson correlation coefficient was verified when comparing the drying kinetic curve generated by the ANN model with the one obtained during the validation experiments.
