The effect of bamboo virgin pulp addition to the recycled pulp in enhancing the recycled paper's mechanical properties was evaluated. Malaysian bamboo virgin pulp used in this research were Bambusa vulgaris (Aur bamboo), Gigantochloa levis (Beting bamboo), and Gigantochloa scortechinii (Semantan bamboo). The addition of 2.5, 5, 7.5, and 10 wt% of bamboo virgin pulp improved the burst index, folding endurance, tearing index, and tensile index of the recycled paper from 2.27 to 3.17 kPa.m2/g, 7 to 15 double folds, 5.98 to 8.27 mN.m2/g, and 24.86 to 32.40 Nm/g, respectively. These were equivalent to the increment percentage for burst index, folding endurance, tearing index, and tensile index at the range of 6.61 to 39.65%, 28.57 to 114.29%, 15.72 to 38.59%, and 10.50 to 33.87%, respectively. The application of bamboo virgin pulp is very promising in improving the recycled paper's mechanical properties and this could be further extended in enhancing the other properties such as physical and optical paper properties.

The main objective of this work was to explore the prospects of producing pulp and paper from leftover lignocellulosic fibers. In this study discarded Cocos nucifera fibers were collected from an abandoned site and were washed thoroughly. FTIR analysis, chemical composition and fiber morphology studies were conducted. FTIR showed the presence of holocellulose and lignin in the fibers. Chemical analysis showed the holocellulose content as 37.8 wt%. Fiber length, fiber diameter, lumen diameter and cell wall thickness were observed using microscope and derived fiber indices that determine the possibility of producing paper were evaluated. The derived indices such as Runkel index, slenderness ratio, co-efficient of rigidity, flexibility coefficient, Luce’s shape factor and Solids factor of the fibers were evaluated as 67.9%, 44.11, 58.83%, 0.199, 0.49 and 278.53x10³ respectively. All these indices are in good agreement with fibers recommended and used for pulp and paper production. High lignin content present in the fibers is a limitation and it can be removed through appropriate delignification techniques. Thus the study showed that discarded fibers can be used for producing pulp, paper and allied products. [ABSTRACT FROM AUTHOR]

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

The relationship between environmental regulation and firm productivity has been widely debated but inconsistencies in findings across different studies. Using detailed firm-level micro-data from 2000 to 2007, this paper employs difference-in-difference combined with matching based on entropy balancing method to explore the effect of environmental regulation on firm total factor productivity (TFP) in pulp and paper industry in China. Our main findings are as following: Firstly, stricter environmental regulation, as represented by the Wastewater Discharge Standards for Pulp and Paper Industry in Shandong province, increases firm TFP significantly. Moreover, the coefficients of interest are robust to multiple robustness checks. Secondly, dynamic effects estimates reveal that when faced with this phase-in environmental regulation, firms take the foreseeably increasing strictness into account from the very beginning and prefer to take one-step adjustment to reach full compliance. Thirdly, potential mechanism analysis finds that the positive effect mainly comes from the improvement of resource allocation efficiency within firms. Fourthly, the heterogeneity test indicates that the effect of environmental regulation on firm TFP is heterogeneous across firms with different sizes, ages, ownerships, capital intensity, and export status. Finally, this paper provides convincing and insightful evidence that environmental regulation has the potential to achieve the dual goals of environmental sustainability and economic growth and is thus of broader significance for understanding the enforcement of environmental regulation in developing countries.

Predictive maintenance strategies are becoming increasingly more important with the increased needs for automation and digitalization within pulp and paper manufacturing sector. Hence, this study contributes to examine the most efficient pre-processing approaches for predicting sensory data trends based on Gated Recurrent Unit (GRU) neural networks. To validate the model, the data from two paper pulp presses with several pre-processing methods are utilized for predicting the units' conditions. The results of validation criteria show that pre-processing data using a LOWESS in combination with the Elimination of discrepant data filter achieves more stable results, the prediction error decreases, and the predicted values are easier to interpret. The model can anticipate future values with MAPE, RMSE and MAE of 1.2, 0.27 and 0.30 respectively. The errors are below the significance level. Moreover, it is identified that the best hyperparameters found for each paper pulp press must be different. [ABSTRACT FROM AUTHOR]

The demand for particleboard has been increasing over the years. Currently, most particleboards are produced from wood which may not be sustainable in the long term. Therefore, there is need of exploring alternative materials such as making particleboards from waste materials. This study investigated the mechanical properties of particleboard consisting of waste leather shavings and waste papers blended together by unsaturated polyester. A single-layered particleboards were manufactured using compression method. Different resin contents (60%, 70%, 80%, and 90%) and leather/paper ratios (100:0, 25:75, 50:50, 75:25) were used to determine the effects on the mechanical properties (internal bond, bending strength, compression, and impact strength) of fabricated boards. From the results of this study, it was found that leather shavings and waste papers can be used as alternative raw materials for particleboard production and that mechanical properties were depended on the resin content and the blend ratio. Also, mechanical properties were reduced with resin content increment, except for impact strength, and improved by high paper blend ratio. It could be concluded that the produced particle panels could be used for indoor application or interior equipping. Additionally, it is recommended that further studies can be done on morphological analysis to establish the bonding between the particles and matrix. [ABSTRACT FROM AUTHOR]

The paper highlights how significant characteristics of liver can be modeled in tissue-engineered constructs using unconventional scaffolds. Hepatic lobular organization and metabolic zonation can be mimicked with decellularized plant structures with vasculature resembling a native-hepatic lobule vascular arrangement or silk blend scaffolds meticulously designed for guided cellular arrangement as hepatic patches or metabolic activities. The functionality of hepatocytes can be enhanced and maintained for long periods in naturally fibrous structures paving way for bioartificial liver development. The phase I enzymatic activity in hepatic models can be raised exploiting the microfibrillar structure of paper to allow cellular stacking creating hypoxic conditions to induce in vivo-like xenobiotic metabolism. Lastly, the paper introduces amalgamation of carbon-based nanomaterials into existing scaffolds in liver tissue engineering. Plain Language Summary Unconventional scaffolds have the potential to meet the current challenges in liver tissue engineering- loss of hepatic morphology and functions over long-term culture, absence of native-like cell-cell and cell-matrix interactions, organization of hepatocytes into lobular structures exhibiting metabolic variations-which hinder pharmaceutical analysis, regenerative therapies and artificial organ development. Paper with cellulose microfibril network develops cellular aggregates with hypoxic conditions that influence enzymes of xenobiotic metabolism proving to be a better scaffold for hepatotoxicity testing compared with conventional monolayers in tissue culture plates. Decellularized plant stems provide already-built vasculature to be exploited for the development of intricate vessel networks that exist in hepatic lobules aiding in regenerative medicine for hepatic pathologies. Fibrous plant structures are excellent materials for the immobilization of hepatocytes and improve albumin secretion enabling their use in bioartificial liver development. Biomimicry of metabolic zonation in hepatic lobules can be achieved with perfusion culture using silk blend scaffolds with varying proportions of the liver matrix that orchestrate cellular function. The mechanical properties of silk allow the fabrication of structures that resemble liver anatomy to generate native-like hepatic lobules. Nanomaterials have immense potential as a component of composite material development for scaffolds to achieve improved predictive ability in pharmacokinetics. Most of these unconventional scaffolds have the added advantage of being readily available, accessible, affordable and sustainable for liver tissue engineering applications. Conclusively, the shift of attention away from conventional scaffolds poses a promising future in the field of tissue engineering. Graphical Abstract Article highlights Limitations of 2D culture: Current 2D culture practices cannot achieve the complexity of hepatic tissue including metabolic zonation, lobular organization, extensive vasculature, existence of multiple cell types. Splenic scaffold: Spleen proves to be the excellent choice of decellularized organ for liver tissue regeneration, however, this cross-organ recellularization procedure is not ideal for clinical translation. Plant-based scaffold: Selecting plant material that matches hepatic tissue mechanical properties and anatomical features including the channel arrangements (central vein and portal triad) help hepatic regeneration and pathological modeling. Naturally fibrous plant materials have the potential to be excellent platforms for bioartificial liver development based on high hepatocyte adherence and function. Paper-based scaffold: Hepatocyte culture on functionalized filter paper forms a physiologically more relevant model for hepatotoxicity assessment particularly because of higher activity of drug metabolizing enzymes. Silk-based scaffold: Hepatic lobular organization that supports metabolic zonation can be mimicked by varying ECM content in silk blend scaffolds to create native-like oxygen and nutrient gradient. CNT-based scaffold: Exceptional properties of carbon nanotubes make them ideal to mimic liver ECM allowing formation of hepatic spheroids with in vivo like characteristics- bile canaliculi, polarity and drug clearance.

In Nazi Germany (1933–45), reclaiming waste became an intrinsic component of the regime's economy as well as its ideological, racial, and expansionist ambitions. National Socialist interventions into waste streams began in 1934 with salvage campaigns. The state then brought urban waste policies and municipal waste services under its control, restructuring and 'Aryanising' the waste salvage trade. Moreover, both consumers and producers were prompted to collect and reprocess waste. Over time, the gradual expansion of the Nazi waste recovery policies and campaigns – here referred to as the 'Nazi waste exploitation regime' – brought forth a determined vision of a circular economy in which no waste whatsoever should escape its reclamation for the national community or Volksgemeinschaft. This article sketches the actors, structures, and objectives of this waste exploitation regime for the case of rags and paper and uncovers its entanglement with Nazi racist and genocidal ideology and expansionism.

Prophylaxis with emicizumab, a bispecific monoclonal antibody that mimics FVIII function, has shown encouraging results in clinical trials in terms of efficacy and safety. However, current experience is limited, and many areas of concern to clinicians have yet to be reviewed. This paper reviews the experience of hemophilia A patients treated with emicizumab based on the results of clinical trials and real-life studies. The authors place special emphasis on issues such as the management of these patients in situations of hemorrhage and/or surgical interventions, joint health or laboratory monitoring. Treatment with emicizumab has been shown to improve joint health and reduce bleeding, of particular interest to patients with inhibitors and high bleeding rates. However, there are still concerns about its administration in neonates and previously untreated patients due to limited reported experience. Laboratory monitoring is not strictly necessary due to the stable pharmacokinetics emicizumab has been shown to exhibit, however, tests that globally assess hemostasis may be useful especially in cases of bleeding or surgery. The authors are also of the opinion that prophylaxis before minor surgery is not necessary and that major surgeries can be safely performed with additional prophylactic coagulation factor.

In Ethiopia, the dairy cows' major feed resources are natural pasture and crop residues, both of which are nutritionally low and do not even satisfy the maintenance requirement. Consequently, dairy productivity per head is low in the country. This paper reviews the existing knowledge of negative energy balance (NEB) and summarizes its implication on production and reproduction parameters, as well as the monitoring tools as a means of intervention in minimizing the effect on dairy cows. The presence of NEB in late gestation and early lactation of dairy cows could contribute to both short and long-term negative effects on production and reproduction ability. Lower body condition, reduced milk production, a change in the milk fat to protein ratio, an increasing incidence of health problems, a late time to become estrus, delayed ovarian cycle, and a lower conception rate are the common implications. Through the knowledge created so far, it can be concluded that NEB is almost a common phenomenon in transitional high milking dairy animals, but there is a possibility to shorten its persistence through strategic supplementation using the NEB monitoring tools.

The article examines Soviet paper reuse as an ideological, economic daily practice, implemented through the advanced, but hitherto undescribed Soiuzutil'waste collecting system by the early 1930s as the reverse side of Stalinist industrialization. It argues that Soiuzutil'waste paper handling attempted to form a new socialist collective by reworking old print while cultivating citizens as classless scrap-collectors, for the sake of an (ir)rational resource optimization. While World War II intensified recycling efforts among the Allied and Axis powers, invasion and evacuation damaged Soviet waste collection to a point where no return of paper into a centralized system was possible. War forced printers and consumers to retreat to local self-supply networks, as paper remained a crucial, yet scarce resource. By analyzing technical-educational literature and correspondence of the reutilization offices, the article demonstrates the changing attitudes in the Stalinist war economy, the industries, and the population towards mobilizing and saving paper.

A simple method for preparing chelated calcium from black liquor produced in the paper industry was studied. Various factors influencing the chelation rate of Ca2+ were studied, including the system pH, reaction temperature, reaction time, reaction solution ratio. The optimum reaction conditions are as follows: the system pH, reaction temperature, reaction solution ratio (V(CaCl2):m (Black liquor)) and time were 5.6, 25°C, 1:20 and 60 min, respectively. The maximum Ca2+ chelation rate was 88.75%. The characteristics of chelated calcium fertilizer in black liquor were studied by Fourier transform infrared, scanning electron microscope. The results indicated that the CaCl2 could be chelated by the black liquor from paper-making industry, and showed a high chelating rate. [ABSTRACT FROM AUTHOR]

The aim of this study was to investigate the properties of concrete with waste paper ash (WPA) as cement replacing material. The chemical composition of WPA was reported, and Portland cement was partially replaced with 0%, 5%, 10%, 15%, and 20% of WPA to explore its effect on both fresh and hardened properties of C—25 concrete. The result of this study indicated that the chemical compositions of WPA were not classified as Pozzolanic material. Setting times of blended cement paste with WPA were lengthened and its consistency was also increased. The cement paste with replacement up to 10% showed a normal consistency within the standard range. The workability of concrete was tested immediately after preparing the concrete mix, whereas the compressive strength was tested after 7 and 28 days of curing. The results indicated that the workability of concrete containing WPA decreases as the WPA content increases. This study also revealed that there is a significant improvement in the compressive strength of concrete. Replacement of ordinary Portland cement by WPA up to 10% results in better compressive strength than that of the control mix. An improvement of 5.6% & 1.2% was observed, respectively, when compared with the 28-day compressive strength of the control mix. But the compressive strength decreases as the WPA replacement increases over 10%. Maximum compressive strength of 37.89 MPa was obtained for concrete containing 5% of WPA. [ABSTRACT FROM AUTHOR]

Strength properties of paper are of great significance in terms of its mechanical performance and are attributed to cellulosic fibers. When filler is used in papermaking, the cost and strength properties get reduced but optical properties are improved. So far, modification of fillers using chitosan (CH) is not explored in such a way that all aspects of wet-end of papermaking get covered. The novelty lies in showing the effect of CH as filler modifier at various doses on different fillers and the wet-end application of modified fillers at different doses along with other additives used in papermaking. The impact of addition of modified fillers on end paper properties is also analyzed. Here, CH was applied to modify fillers characteristics so that the ash in paper can be increased without compromising the strength properties. Three different doses (0.25%, 0.50% and 1.00%) of CH were added to the fillers. The addition of modified fillers to bleached mixed hardwood (BMHW) pulp increased the filler retention in paper while the reduction in strength properties was found to be less and in some properties even an increase was observed. The particle size distributions of fillers were found to be affected after modification of fillers. [ABSTRACT FROM AUTHOR]

This paper deals with the study of the chemical composition of cow dung and the paper-making from cow dung. With the insight into such data, we considered the effect of cooking temperatures and the potassium hydroxide concentration on paper performance. The relationship between cow dung fiber, such as morphology, chemical composition, crystallization, and chemical state structure, and paper performance were studied. Meanwhile, the mechanical performance of cow dung paper and the degradation of cow dung paper in soil were investigated in this work as well. At 100°C, the residue from cooking cow dung decreased and stabilized. Fiber yield in cow dung peaked at 10% KOH concentration. The lignin-hemicellulose C=O bonds were completely broken making the material softer and looser. At 42 °SR Schopper - Riegler’s Degree (SR) pulping, the polymerization was 1126, and the average fiber length and width were 1245 μm and 18.3 μm. Cow dung paper had the best mechanical performance at 42 °SR of 2.48 KPam² /g burst index, 4.83 mNm² /g tear index, and 26.72 Nm/g tensile index, respectively. This work demonstrates that cellulose fiber, extracted from cow dung, is suitable for paper applications and provides new insight into cow dung recycling. [ABSTRACT FROM AUTHOR]

This report explores the history of Puerto Rico's relationship with the United States military and the resistance against militarization. Since the U.S. invasion in 1898, Puerto Rico has experienced the progressive takeover of land for military purposes, resulting in environmental damage and health repercussions. The resistance against militarism has taken various forms, including civil disobedience, marches, and armed struggle. The report showcases a collection of political propaganda, such as posters and pasquines, which were used to spread anti-militarist messages and mobilize people. These materials provide insight into the themes, styles, and campaigns of leftist propaganda between 1960 and 2000, highlighting the power imbalance between the armed forces and the common people. The report includes images and descriptions of selected propaganda pieces, demonstrating the diversity of styles and messages. [Extracted from the article]

Pineapple leaf fibers (PALF) were biopulped using Trametes versicolor, and the resulting biopulp was bleached with xylanase-enzymatic treatments. The biopulping was extensively described using determinations of fiber morphology, color, chemical composition, extractive content, and thermal stability using the structural characteristics determined by XRD and paper properties. The results showed that the chemical and enzymatic treatments shortened the fiber, almost to 50%, and the Kappa index decreased from 27 to 13. Cellulose and holocellulose contents increased from 65% to 74% and from 86% to 91%, respectively, but extractives, lignin (from 12% to 4%), pentosans (from 25% to 14%) and the crystallinity decreased from 58% to 67% in both chemical bleaching and further xylanase-enzymatic processing. Xylanase)enzymatic processing allowed us to obtain whiter (increased lightness color and decreased redness and yellowness tonality) and heavier paper, even though it presented decreased mechanical properties (decreased stress resistance, rupture length, tear resistance and index longitudinal tearing). The xylanase-enzymatic treatment with the best pulping and paper proper)ties is when the biopulp is treated with a xylanase enzyme concentration of 0.04% (w/w). [ABSTRACT FROM AUTHOR]

The deterioration of fiber properties during recycling processes, especially the loss of tensile strength, raises concerns that paper products made from recycled fibers might not satisfy quality requirements. The purpose of this paper is to estimate the deterioration of tensile strength and the damage in paper sheets made of recycled fibers using the theory of damage mechanics and machine learning methods. Experiments were carried out to recycle wood fibers and nonwood fibers four times, and the physicochemical properties of the handsheets made from these fibers were measured after each recycling. Water retention value and relative bonded area were selected as the features to estimate and predict tensile strength during recycling because they had strong correlations with tensile strength. This paper proposed a damage index to quantitatively express the severity of the damage in paper sheets based on the experimental investigation and the theory of damage mechanics. Thus, the deterioration of tensile strength could be estimated and predicted. To determine the damage index, a curve fitting model based on the hyperbolic theory of pulp properties was developed. The proposed quantitative expression of the damage index is: D = (Ds - h)²/a2 - (Dh - k)²/b2, where the coefficients were determined through the curve fitting model. This paper also developed a long short-term memory recurrent neural network model to determine the damage index according to the sequence of recycling. Both models were trained with the experimental data of water retention value and relative bonded area. The estimation and prediction by the curve fitting model were more accurate than those of the neural network model. The root mean square errors by the curve fitting model were 0.0278 for estimation, 0.1667 for prediction; and by the neural network model were 0.2445 for estimation, 0.2206 for prediction, respectively. After the damage index was determined, the deterioration of tensile strength then could be calculated as T = T0 (1-D). [ABSTRACT FROM AUTHOR]

Publications in Renal Failure in Science Citation Index Expanded (SCI-EXPANDED) between 1992 and 2021 were analyzed. Six publication indicators: total, independent, collaborative, first author, corresponding author, and single author publications as well as their related citation indicators, were used to compare performances of countries, institutes, and authors. Comparison of the highly cited papers and journal's impact factor (IF) contributors was discussed. In addition, the main research topics in the journal were presented. Results show that China published the most total articles and reviews, as well as the first-author papers and corresponding-author papers in the journal. The Chang Gung Memorial Hospital in Taiwan ranked the top in five publication indicators: total, single-institution, inter-institutionally collaborative, first author, and corresponding-author papers. A low percentage of productive authors emerged as a journal IF contributor. Similarly, only a limited relationship between highly cited papers and IF contributing papers was found. Publications related to hemodialysis, chronic kidney disease, and acute kidney injury were the most popular topic, while meta-analysis was new focus in the last decade in the journal.

"Settler Colonial City: Racism and Inequity in Postwar Minneapolis" by David Hugill examines the history of racism, inequity, and settler-colonial structures in Minneapolis, particularly focusing on the post-World War II era. The book explores the impact of urban change, racialized policing, and American imperialism on marginalized communities, with a particular emphasis on Indigenous peoples. Hugill highlights the structural barriers faced by marginalized groups and the need to dismantle white supremacist and settler-colonial structures. While the book primarily focuses on the violent aspects of settler-colonial urban policy, it also touches on the need to examine more subtle elements such as access to education, healthcare, and legal services. Overall, the book provides a critical perspective on the history of Minneapolis and challenges the perception of the city as progressive and inclusive. [Extracted from the article]

Bamboo leaves are a resource of cellulose fibers that can be further developed into value-added products. In this research, cellulose nanofibers were obtained from Tinwa bamboo leaves, and then chemically modified with (i) hexadecyltrimethoxysilane (HDTMS) and (ii) perfluorooctyltriethoxysilane (POTS). The modified nanofibers were then used as a hydrophobic biopolymer coating on paper, as an alternative to commonly used fossil-based coatings. Hydrophobicity in terms of surface and bulk properties of the coated paperboards was investigated. The results showed that the hydrophobic coatings obtained provided a high contact angle up to 141° and a decrease of water penetration speed during immersion up to 94% when using ultrasonic technique. The coated paperboards exhibited color difference values compared with an uncoated paperboard in the range of 0.4 to <2 which is hardly distinguishable from the human eye. These results suggest that a biopolymer obtained from modified bamboo leaves does in fact provide a suitable replacement for hydrophobic coating on paper. [ABSTRACT FROM AUTHOR]

Commercial Chinese ink was employed to disperse pristine vapor-grown carbon nanofibers (VGCNFs) in aqueous suspensions via horizontal ball milling. The obtained suspension was used to fabricate conductive paper-based composites through filtration-deposition onto filter paper. It was found that the carbon black particles from the Chinese ink helped separate VGCNFs and acted as connection points between the VGCNFs, while the glue reinforced the conduction network. Thus, the VGCNF-ink/paper ternary composite showed sufficiently low sheet resistance. With merely 2.5 mg·cm−2 VGCNFs, the sheet resistance could be reduced to 4.5 Ω·sq−1. As a proof of concept, these paper-based composites were directly used as electrodes of solid-state symmetric electronic double-layer capacitors (EDLCs) and the substrate for the electrodeposition of MnO2 to achieve higher electrochemical performances. The EDLCs fabricated with 2.5 mg·cm−2 VGCNFs showed a specific capacitance of 224 mF·cm−2 at a current density of 1 mA·cm−2, which was retained by 86.4% after 10,000 charge-discharge cycles. Moreover, thanks to the high electrical conductivity and the porous structure, the MnO2 decorated paper-based composites exhibited dramatically enhanced specific capacitance. It is believed that our finding offers an idea to directly utilize commercial Chinese ink for the fabrication of electrode materials. [ABSTRACT FROM AUTHOR]

This article shows how companies can circumvent competition legislation by developing new informal ways of cooperation. We focus on the case of the Nordic pulp and paper industry which was particularly eager to set up cartels. Scholars analysing this sector can utilise exceptionally rich sources that reveal how industrialists reacted to the introduction and development of European competition policies. The article shows that companies defended their collusive practices by making them less transparent and more informal than before, a change that did not automatically lessen their effectiveness. Tougher competition policies also encouraged industrialists to create new giant companies. [ABSTRACT FROM AUTHOR]

Despite the advancement of technologies and tools used to design and display building elements in construction, design communication on construction sites still heavily relies on 2-dimensional drawings. Paper-based floor plans often reference other paper drawings to deliver design intent to construction site crews. This complicated process sometimes results in the poor transfer of design intent between the designers and construction crews, which can cause quality, safety, and productivity issues in construction sites. How can the process of access to information in 2D drawings be improved to reduce the need to reference different sheets? This study responds to this question by implementing an AR workflow that provides more straightforward access from paper-based floor plans to digital design information without the need to refer to other sheets. In this paper, the current process of viewing and accessing information using 2D drawings was investigated. Then an AR workflow was created to facilitate access to the design information. Finally a case study was used to test the AR workflow against the conventional method of using 2D drawings, considering variables such as time, error, and user preference. The results showed that the AR workflow is more favorable and could improve time and reduce errors. [ABSTRACT FROM AUTHOR]

Reproducibility, the ability to reproduce the results of published papers or studies using their computer code and data, is a cornerstone of reliable scientific methodology. Studies where results cannot be reproduced by the scientific community should be treated with caution. Over the past decade, the importance of reproducible research has been frequently stressed in a wide range of scientific journals such as Nature and Science and international magazines such as The Economist. However, multiple studies have demonstrated that scientific results are often not reproducible across research areas such as psychology and medicine. Statistics, the science concerned with developing and studying methods for collecting, analyzing, interpreting and presenting empirical data, prides itself on its openness when it comes to sharing both computer code and data. In this article, we examine reproducibility in the field of statistics by attempting to reproduce the results in 93 published papers in prominent journals using functional magnetic resonance imaging (fMRI) data during the 2010–2021 period. Overall, from both the computer code and the data perspective, among all the 93 examined papers, we could only reproduce the results in 14 (15.1%) papers, that is, the papers provide both executable computer code (or software) with the real fMRI data, and our results matched the results in the paper. Finally, we conclude with some author-specific and journal-specific recommendations to improve the research reproducibility in statistics. [ABSTRACT FROM AUTHOR]

The Continental Congress foray into printed money during the American Revolution was so disastrous that the United States printed no more money for nearly a century, the one exception being a brief period during the War of 1812. After that Congress chartered and unchartered its national bank twice. The American economy henceforth (1816–1836) was often structurally short of coins, and without any national coinage Americans had to find substitute forms of currency to finance the burgeoning economy. The Supreme Court ruled that sovereign States and individuals could authorize both State and private banks to issue their own notes. In consequence, nearly all paper money in circulation was either State or private banknotes based on a limited reserve of gold. This generally proved insufficient to adequately fund major infrastructure projects. The federal government also had no institution for raising or transferring large amounts of money to fund these national improvements. Nonetheless, Hamilton's U.S. Bank, without the help of a national currency, was an institutional precursor for what would not take final form until 1913. There would be no Federal Reserve today without the Whig-Republican agenda institutionally incarnated in the First and Second U.S. Bank. [ABSTRACT FROM AUTHOR]

In cotton yarn bundles and fabric layers, wicking and rate are accounted as crucial indigenous liquid transportation properties, playing a significant role in temperature reduction on their surfaces and being used to extend the food and agricultural storage life. In this article, manual test methods are described to measure water wickability and wicking rate of cotton yarn bundles and plain weave fabric layers. These methods described the water flow through the in-plane surface of yarn bundles and fabric layers oriented in either vertical or horizontal lines without external force. The wicking lengths and wicking growth rates in both untreated and treated cotton yarn bundles and fabric samples in either in-plane vertical or horizontal orientations were compared. The highest to lowest wicking length and rate were found in the treated yarn bundles, treated fabric layers, untreated yarn bundles, and untreated fabric strips, respectively. The wicking height and length obtained in untreated yarn bundles and untreated fabric layers was lower than the Kraft paper. The higher wicking and rate values indicate a considerable potential for liquid water migration. The results indicated that treated yarn bundles and fabric layers that are oriented horizontal direction are the best options for constructing capillary evaporative cooling. [ABSTRACT FROM AUTHOR]

Creativity is an important skill for engineers but many students face a lack of experience in idea generation, often compounded by low-self efficacy towards creativity. Providing students with online training modules has been suggested as one solution. However, the literature demonstrates using a computer can influence performance and self-efficacy in a different manner to using pen-and-paper. There is a current lack of research on whether computers may influence self-efficacy during idea generation tasks. Two experiments involving computer-based and pen-and-paper groups were designed. Groups were provided with templates that guided them through the process of applying an idea generation technique and were given sixteen minutes to generate ideas to solve a presented problem. Results revealed that students' performance was similar and using a computer does not negatively influence self-efficacy. This shows that students can engage in idea generation learning tasks using computer-based modes without negatively influencing performance or self-efficacy, suggesting an avenue for educators to engage students with building creativity skills.

Residential owned solar panels mounted on roof-tops generated 1.4% of the U.S. electricity supply in 2022. Utilities compensate residential customers using a net metering system by which each kilowatt-hour generated by the customer reduces the customer's bill by the amount the utility charges for one kilowatt. Despite the small impact of roof-top solar on the total market, in 2022, thirty-two states conducted ninety-four proceedings investigating whether to change the net metering system. In these proceedings, utilities advocated changing the rates to discourage residential investment in solar panels. Utilities argue that net metering provides a subsidy to solar customers because the rate the utility pays is greater than the avoided cost of energy. That excess payment allows solar customers to avoid paying for the distribution network. The cost of the distribution network is shifted to non-solar customers. This article will evaluate these claims. It will show that if the social cost of carbon were in the calculation, it would generate a Kapp cost shift from solar customers to non-solar customers. The size of the Kapp cost shift is greater than the cost of distribution networks, reversing any private cost shift that utilities have estimated. [ABSTRACT FROM AUTHOR]

Introduction: Freezing cold injuries (FCI) are a common risk in extreme cold weather operations. Although the risks have long been recognised, injury occurrences tend to be sparse and geographically distributed, with relatively few cases to study in a systematic way. The first challenge to improve FCI medical management is to develop a common nomenclature for FCI classification. This is critical for the development of meaningful epidemiological reports on the magnitude and severity of FCI, for the standardisation of patient inclusion criteria for treatment studies, and for the development of clinical diagnosis and treatment algorithms. Methodology: A scoping review of the literature using PubMed and cross-checked with Google Scholar, using search terms related to freezing cold injury and frostbite, highlighted a paucity of published clinical papers and little agreement on classification schemes. Results: A total of 74 papers were identified, and 28 were included in the review. Published reports and studies can be generally grouped into four different classification schemes that are based on (1) injury morphology; (2) signs and symptoms; (3) pathophysiology; and (4) clinical outcome. The nomenclature in the different classification systems is not coherent and the discrete classification limits are not evidence based. Conclusions: All the classification systems are necessary and relevant to FCI medical management for sustainment of soldier health and performance in cold weather operations and winter warfare. Future FCI reports should clearly characterise the nature of the FCI into existing classification schemes for surveillance (morphology, symptoms, and appearance), identifying risk-factors, clinical guidelines, and agreed inclusion/exclusion criteria for a future treatment trial.

The inner lining of the urinary bladder (urothelium and lamina propria, or bladder mucosa) has an important role as a tissue barrier between stored urine and the underlying smooth muscle, as well as in the modulation and regulation of bladder contractility. However, the individual influence of the apical urothelial layer on the contractile activity of this tissue is uncertain. The aim of this experiment was to identify the contractile activity of the lamina propria after removal of the urothelium. Several methods were used to mechanically disrupt the urothelium, including dabbing the tissue with a paper towel, longitudinal swipes with a cotton bud, or a longitudinal scrape with the edge of a scalpel. Hematoxylin-eosin staining was utilized to determine the level of removal of the apical urothelial cells. Spontaneous contractile activity was measured in organ baths, and responses to the agonists carbachol and isoprenaline were obtained. Three longitudinal swipes with a cotton bud was found to be the optimal method to remove the majority of the urothelium without damaging the lamina propria. Upon removal of the urothelium, the spontaneous activity of the tissue was unaltered. Similarly, responses to carbachol (1 µM) and isoprenaline (1 µM) were not affected after removal of the urothelium. The urothelium can be effectively removed without damaging the lamina propria. This apical tissue layer is not responsible for mediating the increases to spontaneous phasic activity or tonic contractions of the bladder mucosa (urothelium with lamina propria) when muscarinic or adrenergic receptors are stimulated. This research presents the lamina propria as the important cell layer mediating the overall contractile activity of the bladder wall. [ABSTRACT FROM AUTHOR]

A paper-based electrode is a very attractive component for a disposable, nontoxic, and flexible biosensor. In particular, wearable biosensors, which have recently been attracting interest, not only require these characteristics of paper-based electrodes but must also be able to detect various ions and biomolecules in biological fluids. In this paper, we demonstrate the detection ability of paper-based metal electrodes for wearable biosensors as part of a wireless potentiometric measurement system, focusing on the detection of pH and sodium ions. The paper-based metal electrodes were obtained by simply coating a silicone-rubber-coated paper sheet with a Au (/Cr) thin film by sputtering then modifying it with different functional membranes such as an oxide membrane (Ta2O5) and a fluoropolysilicone (FPS)-based Na+-sensitive membrane, corresponding to the targeted ions. Satisfactory and stable detection sensitivities of the modified paper-based Au electrodes were obtained over several weeks even when they were bent to a radius of curvature in the range of 6.5 to 25 mm, assuming use in a flexible body patch biosensor. Moreover, the Na+ concentration in a sweat sample was evaluated using the paper-based Au electrode with the FPS-based Na+-sensitive membrane in a wireless and real-time manner while the electrode was bent. Thus, owing to their complex mesh structure, flexible paper sheets should be suitable for use as potentiometric electrodes for wearable wireless biosensors. [ABSTRACT FROM AUTHOR]

This study investigates the ability of cellulose filter paper coated with silver nanoparticles to removeEscherichia colifrom drinking water. The cellulose filter paper was coated with silver nanoparticles by a chemical reduction method using two different ratios of sodium borohydride and silver nitrate. In consideration of drinking-water quality standards and non-carcinogenic health risks, the optimum sodium borohydride:silver nitrate ratio for coating the cellulose filter paper was determined by comparing the silver in the effluent afterE. coliremoval. For both ratios, 100%E. coliremoval was realised. In terms of the silver in the effluent, only the first two lowest concentrations for both ratios of sodium borohydride and silver nitrate were compliant with the drinking-water quality standards, demonstrating hazard quotients (HQs) between 0.084 and 0.484. On the basis of the highest level ofE. coliremoval with the lowest HQ value, the optimum sodium borohydride:silver nitrate ratio for coating the cellulose filter paper as an antibacterial water filter was 2:1 molar ratio (0.002 M:0.001 M). Silver nanoparticle-coated cellulose filter paper was found to be an inexpensive and easy-to-use emergency antibacterial water filter to generate clean drinking water. [ABSTRACT FROM PUBLISHER]

At a time when the world is critical of the Brazilian government and the loss of Amazonian rainforest, Brian J. Godfrey casts his 40-year gaze on Rio de Janeiro. Geographer Godfrey deftly uses various scales of analysis - global, hemispheric, national, regional, metropolitan, and neighborhood - to point out how memory can be used to reinvent places both in Rio and elsewhere. Godfrey's real nugget is chapter 3's examination of Little Africa in Rio. [Extracted from the article]

This article presents a case study of how the Renminbi won the currency war in Shanghai between 1949 and 1950. This case study supports the proposition of chartalism and MMT that money is a creature of the state, and in two ways deepens our understanding of the role of the state in the sovereign currency system. First, taxation is not the only way to drive money. The Shanghai government also drove money by supplying goods. Second, the outcome of a currency war depends on many historical factors, and the government plays an important role by changing the conventions that shape people's monetary behavior. The Shanghai government adopted anti-inflation policies to transform the conventions of valuing commodities and metallic currencies over paper currencies. [ABSTRACT FROM AUTHOR]

Environmental sustainability urgently needs to be embraced as a driver of development for society and industry. While researchers and practitioners herald numerous benefits when adopting eco-efficiency and circular economy approaches, these green solutions are yet to become pervasive principles for designing and operating industrial systems. This study reviews the last ten years of research contributions from the International Federation for Information Processing Working Group 5.7 (IFIP WG5.7) on Advances in Production Management Systems (APMS) through its dedicated annual conference. A systematic literature review method was employed to map the APMS conference papers against eco-efficiency principles and to identify how these principles have been addressed by this research community. A cross-thematic analysis further describes the trends around dominant themes in production research. Finally, the paper concludes with an update on eco-efficiency principles applied to manufacturing and a proposed framework to consider more systematically the environmental implications of advances in production research.

This paper proposed phytoliths as promising for identifying and distinguishing sources of fibre in Chinese handmade papers. For an initial methodological exploration, two types of Raw Xuan (unprocessed Xuan paper) and the two plant materials used in making them—namely rice straw and bark from blue sandalwood (Pteroceltis tatarinowii Maxim.)—were collected. The dry ashing method was used to extract phytoliths from Raw Xuan and its plant materials. The results can be summarized as follows. First, phytoliths characteristic of rice (Oryza sativa) were abundant in both rice straw and Raw Xuan. By looking for rice phytoliths, it is possible to tell whether or not rice straw fibre is used in a particular paper. Second, hair cell phytoliths were observed in considerable quantities in blue sandalwood bark, but absent in the examined papers. Heat experiments showed that phytoliths in blue sandalwood were resistant to long-term heat and they would unlikely be eliminated when exposed to the heat in papermaking (with heat source barely above 200°C). It is hypothesised that they dissolved while cooked in an alkaline pH (limewater). Further studies are necessary to understand whether phytoliths in blue sandalwood—while cooked in limewater—undergo morphological changes and, if yes, how. [ABSTRACT FROM AUTHOR]

This project investigated airborne particle releases derived from paper shredding. The characteristics of these emissions have not been studied previously. The objective of this project was to characterize released particles in terms of particle size distribution, particle mass and number concentration, particle morphology and chemical composition, as well as the structure of paper fibers. A significant amount of paper particles were found in the close vicinity of an unenclosed paper shredder during shredding and the manual manipulation of shredded paper. The particle release from shredding using two types of printer paper, two types of shredders, and various shredding frequencies was measured inside the shredder basket. The particles released from paper shredding were found to be in the nanometer to micrometer size ranges, and the particles contained calcium and other metal elements. Manual stirring of shredded paper released the highest particle concentration as measured at the opening of the container. Shredding with 30-s intervals increased the duration of airborne particle release as compared to intermittent shredding. Multiple quantitative analyses were employed to evaluate released particles at various particle size ranges. Two real-time instruments which measured thoracic (<10 μm) and respirable (<4 μm) particle sizes showed comparable concentrations measured inside and outside of the shredder basket.
