This project explored Japan’s changing security attitudes from 1972 to 2014 under the scope of its official defense white papers, using a method of sentiment analysis. Consistent with previous studies, Japan was highly cooperative with China during the period from 1972 to 1992, a period rightfully characterized as the “Golden Age.” Starting from 1993, faced with a rising China, Japan maintained an overall neutral posture on the official and legal level towards China, but subtle attitudinal changes could be seen. While Japan had praised China for its cooperative efforts to denuclearize the Korean peninsula and active involvement in UN peacekeeping, it also pointed to China’s covert purposes for engaging in such activities and repeatedly raised concerns about a perceived violation of state sovereignty by China on the “Senkaku Islands,” as well as over Beijing’s human rights issues and lack of transparency in military spending. The current project shows that Japan has continued to adopt non-confrontation, non-provocative language even when describing its disputes with China.

WOS:000967659000009 The utilization of plant extraction products from Oeneanthe pimpinelloides (Apiaceae family) seeds were investigated in terms of their use as an insecticide control of packaging materials. The aim was to investigate their insecticidal effects against the flour beetle Tribolium castaneum. The Oeneanthe pimpinelloides seeds were extracted with methanol. By using the liquid-liquid extraction method, the hexane extract (II) was separated from the methanol extract (I) and hexane and methanol were evaporated. Then, the chemical composition of each sample was determined via gas chromatography–mass spectrometry. The methanol extract predominantly contained tetrahydrofuran, 1-methoxy-2-propanol, 1-methoxy, 2-butoxyethanol, 1-phenylethanone, cyclohexene carboxylate derivative, (3-phenyl-2-propynylidene) cyclopropane, diphenyldiazene, and dihydroxypropyl ester components, while the hexane fraction contained nonane, 1-octanol, decane, undecane, tridecane, alkyl benzene, benzene sulfonic acid, benzoxazine, and hexadecanoic acid components, as well as some derivatives of them. Each fraction was dissolved in DMSO for impregnation on filter paper. The insecticide effects of the paper samples were determined against Tribolium castneum. According to the results, the mortality started after 3 d for each fraction. After 4 d, the hexane fraction indicated total mortality in comparison with the methanol fraction, which showed partial mortality (3/5).

Background: Intelligent food packaging that can monitor food quality and safety is essential in modern commercial trade. Research on the fabrication of environmentally friendly colorimetric labels that can indicate the freshness of food through color changes are needed. Methods: In this study, paper-based colorimetric labels were prepared using filter paper dipped into a solution of Roselle flower extract, and their performance in monitoring shrimp spoilage was investigated. Results: The labels’ response to ammonia vapor shows a distinct color variation from red to greenish-grey, corresponding to a sharp increase in the total color difference (ΔE = 32). The labels are relatively stable during storage at 4°C for up to 20 days. In shrimp freshness monitoring, the color changes from red to purple, which corresponds to increasing levels of total volatile basic nitrogen (TVB-N), and can be observed easily with the naked eye. Conclusion: This suggests that our paper-based colorimetric labels impregnated with Roselle extract show superior performance in detecting shrimp spoilage.

From the end of the nineteenth century and one hundred years onward, home sewing was an important part of many women’s duties, but it was also a pleasure, something that existed parallel with the emerging mass-produced ready-to-wear industry. The paper patterns used for home dressmaking were often sold and distributed through women’s magazines. These pattern sections were both a kind of reader service and a conscious strategy to capture the female target group. This article, based on an analysis of three Swedish magazines, is the first in-depth survey of patterns for home sewing of women’s clothes in Sweden. The study shows how the magazines adapted to changes in society with increasingly easier patterns and ready-cut fabric for their readers. By highlighting women making their clothes in the home, this article contributes to an often-neglected area of women’s memory and fashion history.

本稿では、製紙業界の新市場開拓に向けたイノベーションの効果について寡占市場を前提に理論的に捉え、新市場の拡大が企業の生産性・効率性にどのように影響するのか、大王製紙を例にしてシミュレーション・データによる実証分析を試みた。その結果、新市場の開拓は、長期的に製紙企業の効率性を向上させる効果があり、大王製紙のケースでは、2050年時点の効率性は、好景気であった1990年の効率水準に並ぶことが明らかになった。, This paper takes a theoretical view of the effect of innovation on the development of new markets in the paper industry, assuming an oligopoly market, and attempts an empirical analysis of how the expansion of new markets affects the productivity and efficiency of companies, using Daio Paper as an example, through simulation data. The results showed that the development of new markets has the effect of improving the efficiency of paper companies over the long term, and in the case of Daio Paper Corporation, the efficiency in 2050 is on par with the efficiency level in 1990, when the economy was booming., 特集 経済制度と社会秩序の形成に関する理論実証分析, Special issue: Theoretical and empirical studies on the evolution of economic institutions and social order, 論説(Article)

研究ノート

本研究は日本の大学2 回生が初めて書く英語によるアカデミックペーパーにおいて、文献参照をどのように行っているかを分析したものである。分析には先行研究で提示された5種類の指標を用いた。その指標とはcitation category, integral/non-integral, reportingstructure, rhetorical functions, writer’s stance である。その結果、対象ペーパーの全体の傾向は、同じく学生のペーパーを対象とした類似研究とほぼ共通した特徴を示していることが分かった。また、ライティング経験がより高い対象を分析した先行研究とは、若干の相違点が認められた。

In this work, electrodes based on laser-scribed reduced graphene oxide were fabricated using filter paper as the substrate. To fabricate the electrodes, a water suspension of graphene oxide was filtered to produce a continuous and uniform film of graphene oxide on the filter paper surface. Subsequently, a CO2 laser was used to "write" the working, counter and reference eelctroes by reducing graphene oxide in specific areas to define complete sensors. Referecnce electrodes were then coated with a commercial Ag/AgCl conductive paste to produce a quasi Ag/AgCl reference. As fabricated devices were employed as electrochemical sensors for detection of phosphate ions in water by employing the molybdenum blue method. This method exploits the reaction between molybdate and phosphate ions in acidic media leading to a Keggin-type complex (PMo12O3 40) which, being electrochemically active, enables the indiret detection of phosphate ions. Sensors exhibited high selectivity and sensitive detection of phosphate ions in a wide linear range, from 1 to 20 & mu;M; with a limit of detection of 0.4 & mu;M. To demonstrate that sensors could be utilized for in-situ phosphate ion detection, paper substrate was first pre-loaded with sul-phuric acid and molybdate ions. During analysis, these chemicals were then desorbed directly into the test sample eliminating the need for any kind of external manipulation or reagent addition. Thus, this paper presents the fabrication of a portable, easy-to-use, biodegradable and fast phosphate ions sensor for in situ and real-time monitoring of water quality.

This research was realized with an academic scholarship at the recommendation of Izuru Shinmura, whom under Jugaku studied. From October 1937 to March 1940, Jugaku visited 96 towns and villages on 15 trips. Ryoichi Mizutani, Director of the Labor Division of the Cabinet Statistics Bureau, who was a fellow of Mingei, cooperated with the survey plan. In the survey, Shizuko recorded the scenery of her travels, and Jugaku recorded the professional papermaking process. Jugaku took pictures, collected papers, and brought them home. The culmination of their research is “Papermaking Village Travel Diary” by Jugaku Bunsho and Shizuko. It is highly regarded for its excellent binding. It has scientifically researched and described contents about papermaking at that time. Jugaku strongly criticizes the use of chemical materials to make paper more efficient. Jugaku, who sees paper as a craft, appreciates paper made by old methods using materials that cannot be mixed, but there is a gap between paper manufacturing as an industry and as a craft., 特集 : 近代京都と文化, Special Issue : Modern Kyoto Culture

Foam-assisted web forming and chemical application technologies have great potential to improve manufacturing efficiency and product quality in the paper and nonwovens industries. In this study, the benefits of foam forming and foam-assisted application of chemicals were demonstrated in a pilot machine trial. Uniform high-bulk webs of unrefined bleached softwood kraft pulp (BSKP) and viscose fibers were manufactured by foam forming. It was shown that foam formed low-grammage and high-bulk viscose fiber webs can be strengthened by foam-assisted application of latex onto the wet web. Correspondingly, foam-assisted application of carboxymethyl cellulose (CMC) and anionic polyacrylamide (A-PAM) improved the strength of the foam formed low-grammage and high-bulk BSKP web. Overall, the pilot machine results indicated that material cost savings could be achieved and a high-performance product could be manufactured with foam-based technologies.

Cellulose-based materials represent a renewable, biodegradable, and environmentally friendly alternative to plastic from fossil resources. Nanopaper is a strong and lightweight material formed from cellulose nanofibrils (CNFs). Paper and nanopaper have been considered as excellent alternatives to plastics for use in agriculture and for packaging applications. However, common for both paper and nanopaper is their hydrophilic character, and consequently, poor water-resistance properties. ORMOCER®s are a class of inorganic–organic polymers with excellent barrier and protective properties used for a range of coating applications. Here we present ORMOCER®-coated paper and nanopaper. The coated papers and nanopapers are characterized, both in terms of their morphology, hydrophobicity, and mechanical properties. We demonstrate that the pressure used during the pressing and drying of paper and nanopaper influence their tear and tensile—properties, and that the morphology of the coated nanopaper differs significantly from that of the coated paper. While the ORMOCER® was impregnated within the porous network of the paper, a well-defined two-layered morphology was obtained with the coated nanopaper. Further, the biodegradability of the nanopaper with and without coating was assessed. The degradation study demonstrated that both the pressure used during the pressing and drying of the nanopaper, and the composition of the ORMOCER®, influenced the rate of degradation. Taken together, ORMOCER®-coated paper and nanopaper are promising for the preparation of materials that are both water-resistant, renewable, and biodegradable.

Currently, tissue product producers try to meet consumers’ requirements to retain their loyalty. In perforated products, such as toilet paper, these requirements involve the paper being portioned along the perforation line and not outside of it. Thus, it becomes necessary to enhance the behavior of the perforation line in perforated tissue papers. The current study aimed to verify if the perforation line for 0° (the solution found in commercial perforated products) is the best solution to maximize the perforation efficiency. A finite element (FE) simulation was used to validate the experimental data, where the deviations from the experiments were 5.2% for the case with a 4 mm perforation length and 8.8% for a perforation of 2 mm, and optimize the perforation efficiency using the genetic algorithm while considering two different cases. In the first case, the blank distance and the perforation line angle were varied, with the best configuration being achieved with a blank distance of 0.1 mm and an inclination angle of 0.56°. For the second case, the blank distance was fixed to 1.0 mm and the only variable to be optimized was the inclination angle of the perforation line. It was found that the best angle inclination was 0.67°. In both cases, it was verified that a slight inclination in the perforation line will favor partitioning and therefore the perforation efficiency.

The object of research in this scientific paper is the treatment of waste generated by paper production in industrial landfills. In the part of the paper production process, i.e. in its subsystem for wastewater treatment, a significant amount of solid waste is generated, which ends up in industrial landfills. The reason for the impossibility of returning to the production process lies in the fact that the sludge contains larger amounts of moisture and present chemical components that are isolated in the paper production process or during wastewater treatment. In the experimental part of the paper, a “trial plot” was selected on which seedlings of the paulownia elongate plant were planted in the waste sludge. The process of plant growth was monitored for two years and bioremediation, i.e. transfer of elements from sediments to plants, was analysed by modern instrumental methods. Based on the results obtained by research, it can be said with certainty that Paulownia elongate can be used in bioremediation of areas where these sediments are deposited.

In an article to study the effect of sizing agent and filler on the structural features of paper from the cellulose mass of the inner layer of the bark of mulberry tree branches, mechanical strength, absorbency and sorption properties were studied. Tensile strength was determined on a tensile testing machine by the force causing the destruction of the sample. Surface absorbency at one side wetting was determined by the method of Cobb(30), by determining the mass of water absorbed by the surface of the paper when wetting one side of the test sample. Sorption properties were studied on a high-vacuum setup with mercury gates and McBain quartz balances according to water vapor sorption data. It was found that the internal 2% sizing of the paper pulp with cherry tree resin glue contributes to the strengthening of the paper structure, which is confirmed by the values of mechanical strength and surface absorbency when unilaterally wetted with water, relative to the values obtained when sizing with pine oleoresin rosin glue. When using glue from cherry resin, it is advisable to add 2 g of kaolin to 100 g of pulp from the inner layer of the bark of mulberry tree branches, since the increase negatively affects mechanical strength and hydrophobicity., В статье для исследования влияния проклеивающего вещества и наполнителя на структурные особенности бумаги из целлюлозной массы внутреннего слоя коры веток тутового дерева изучены механическая прочность, впитывающая способность и сорбционные свойства. Прочность на разрыв при растяжении определяли на разрывной машине по усилию, вызывающему разрушение образца. Поверхностную впитываемость при одностороннем смачивании определяли по методу Кобб(30), путем определения массы воды, поглощенной поверхностью бумаги при смачивании одной стороны испытуемого образца. Сорбционные свойства исследовали на высоковакуумной установке с ртутными затворами и кварцевыми весами Мак-Бена по данным сорбции паров воды. Выявлено, что внутренняя 2%-ная проклейка бумажной массы клеем из живицы черешневого дерева способствует упрочнению структуры бумаги, что подтверждается значениями механической прочности и поверхностной впитываемостью при одностороннем смачивании водой, относительно значений, полученных при проклейке канифольным клеем из сосновой живицы. При использовании клея из живицы черешневого дерева целесообразно к 100 г целлюлозной массы из внутреннего слоя коры веток тутового дерева добавлять каолин в количестве 2 г, так как увеличение отрицательно влияет на механическую прочность и гидрофобность.

Lead (Pb) pollution from local mines and industrial use increases risks for human, animal, and plant health. Pectin is an effective chelator of Pb, and it has been shown that a unicellular green alga, Penium margaritaceum, synthesizes pectin in the cell wall. In this study, the ability of P. margaritaceum to remove Pb from an aqueous solution was investigated. Energy dispersive X-ray spectroscopy revealed that two strains of P. margaritaceum accumulated Pb on the cell surface. Hence, P. margaritaceum cells were immobilized on cellulose filter paper. The immobilized algal cells were soaked in 1.0 mg/L Pb solution with gentle shaking for 8 h, and Pb in the solution and on the filter paper was measured by flame atomic absorption spectrometry. The immobilized algal cells continuously decreased the Pb concentration to less than 0.5 mg/L and recovered 31.8–32.7% of added Pb. The specific decrease in Pb and increase in Ca were observed in the presence of 1.0 mg/L each of Ca, Mg, Na, and K. Fourier transform infrared spectra suggested that the carboxylic acid group would be responsible for the adsorption of Pb. This study is the first to demonstrate the effectiveness of the immobilized P. margaritaceum cell in removing Pb from aqueous solutions with simple solid–liquid separation.

Four organic solid wastes (coffee grounds, ground nut shell, paper money sewage sludge and cork powder) have been investigated as bloating inducing agents in lightweight aggregate (LWA) manufacturing when mixed in small proportions (2.5 wt.%) with three types of clays. The pellets obtained were fired in a rotary kiln at the maximum feasible temperature for 4 min. A similar impact was observed both in the working conditions and in the properties of the LWAs, showing that the differences between said residues are not as decisive as those of the clays to which they are added. The organic wastes have played a crucial role in achieving reducing conditions inside the aggregate. Thus, their addition has led to substantial improvements both from an operational point of view, lowering the working temperature, and from a technological perspective, favoring bloating and the development of a highly porous and lightweight structure. Leachate studies have shown that the LWAs meet the regulatory limits. The outcomes of this investigation show that, in line with the precepts of the Circular Economy, the recovery of organic wastes of different nature can have a place in the production of environmentally friendly LWAs

Background Huntington’s disease is a complex neurodegenerative hereditary disease with symptoms in all domains of a person’s functioning. It begins after a healthy start in life and leads through the relentless progression over many years to complete care dependency and finally death. To date, the disease is incurable. The long progressive complex nature of the disease demands multiple disciplines for treatment and care of patient and family. These health care providers need inter- and multidisciplinary collaboration to persevere and be efficacious in this devastating disease trajectory. Discussion The position paper outlines current knowledge and experience alongside the experience and consensus of a recognised group of HD multidisciplinary experts. Additionally the patient’s voice is clear and calls for health care providers with a holistic view on patient and family. Building long-term trust is a cornerstone of the network around the patient. This paper describes a managed care network comprising all the needed professionals and services. In the health care system, the role of a central coordinator or case manager is of key importance but lacks an appropriate guideline. Other disciplines currently without guidelines are general practitioners, nurses, psychologists, and social workers. Guidelines for neurologists, psychiatrists, geneticists, occupational therapists, speech and language therapists, physiotherapists, dieticians, and dentists are being discussed. Apart from all these profession-specific guidelines, distinctive inter- and multidisciplinary collaboration requirements must be met. Conclusions and recommendations The complex nature of Huntington's disease demands multidisciplinary treatment and care endorsed by international regulations and the lay association. Available guidelines as reviewed in this paper should be used, made available by a central body, and updated every 3–5 years. Time needs to be invested in developing missing guidelines but the lack of this ‘proof’ should not prevent the ‘doing’ of good care.

This is a proposal for publishing resource papers as registered reports in the Northern European Journal of Language Technology. The idea is that authors write a data collection plan with a full data statement, to the extent that it can be written before data collection starts. Once the proposal is approved, publication of the final resource paper is guaranteed, as long as the data collection plan is followed (modulo reasonable changes due to unforeseen circumstances). This proposal changes the reviewing process from an antagonistic to a collaborative enterprise, and hopefully encourages NLP resources to develop and publish more high-quality datasets. The key advantage of this proposal is that it helps to promote responsible resource development (through constructive peer review) and to avoid research waste.

Today, legal regulations, along with social awareness, have made waste management a necessity. Depending on the type of waste, technological developments have enabled an increase in the number of approaches, e.g., reusing, recycling, and manufacturing of different products. In this study, low-density boards were produced using different proportions of office waste paper, wood chips, and chopped E-glass fiber. Waste paper and glass fiber formed the middle layer of the boards and wood chips comprised the surface layers. The density, water absorption, and thickness swelling properties of the boards were investigated. Among the mechanical properties, the modulus of rupture, modulus of elasticity, and internal bond strength were determined. The use of wastepaper led to a reduction in the modulus of rupture and modulus of elasticity of the boards. An increase in the glass fiber ratio contributed positively to the water absorption and thickness swelling properties, whereas it directly led to decreases in the internal bond strength, and the modulus of rupture and modulus of elasticity values. Nonetheless, the low-density boards were able to meet the minimum modulus of rupture and modulus of elasticity specified in ANSI 208.1 standards, while only one variation met the IB requirements., U današnje je vrijeme zakonska regulativa, uz društvenu svijest, gospodarenje otpadom učinila nužnošću. Ovisno o vrsti otpada, tehnološki je razvoj omogućio povećanje broja pristupa gospodarenju otpadom, npr. pri ponovnoj uporabi, recikliranju i proizvodnji različitih proizvoda. Za ovo su istraživanje izrađene ploče niske gustoće s različitim udjelima otpadnoga uredskog papira, drvnog iverja i usitnjenih staklenih vlakana. Pritom su otpadni papir i usitnjena staklena vlakna iskorišteni za izradu središnjeg sloja, a drvno je iverje upotrijebljeno za vanjske slojeve ploča. Izrađene su ploče ispitane i utvrđena je njihova gustoća, moć upijanja vode i debljinsko bubrenje. Dodatno su određeni modul loma, modul elastičnosti i čvrstoća raslojavanja. Rezultati ispitivanja pokazali su da je uporaba otpadnog papira pridonijela smanjenju vrijednosti modula loma i modula elastičnosti. Istodobno je povećanje udjela usitnjenih staklenih vlakana imalo pozitivan učinak na vrijednosti upijanja vode i na debljinsko bubrenje, ali je izravno utjecalo i na smanjenje čvrstoće raslojavanja, modula loma i modula elastičnosti. Ipak, izrađene ploče niske gustoće zadovoljile su minimalne zahtjeve norme ANSI 208.1 glede modula loma i modula elastičnosti, a samo je jedna skupina eksperimentalno izrađenih ploča zadovoljila uvjete čvrstoće raslojavanja.

Spatially resolved fluid-flow modulation and its corresponding integration becomes a crucial aspect to consider when designing high-performing paper-based analytical devices. As such, high demand exists for cost-effective techniques able to selectively control flow in patternable regions of the device. In this regard, a solution composed of potassium alum and animal glue; sizing materials used in the fabrication of calligraphy Xuan paper, is successfully adapted for the first time in a revolutionary approach to efficiently modulate the capillary flow in paper microfluidic channels. Flow delays are achieved by coating the substrate systematically through the variation of parameters such as the ratio of alum to glue, the concentration of alum-glue in the solution, and the number of subsequent coating layers of alum-glue. Moreover, digitized patterning with alum-glue is developed to achieve programmable wicking profiles of accelerating, decelerating, and quasi-linear flow displacement by alternating coated and uncoated zones in the channel. Additionally, the influence of alum-glue when performing biometric assays is investigated by performing a horseradish peroxidase activity colorimetric assay and found to have negligible effects on reading, where a negligible difference of 5.2% was observed in an assay performed in a coated paper substrate, compared to an uncoated one.

In the paper by Inna Ganschow, the camp experience in the Soviet Union as a result of forced conscription will be treated, specifically in its artistic processing: secretly written diaries and letters by Luxembourg Wehrmacht soldiers. Contemporary historical research today calls them ego documents – private, handwritten texts of a personal nature. The range of texts to be examined in the lecture ranges from the smuggled out notes and letters that their released comrades took with them to Luxembourg, through diaries, speeches and self-made dictionaries to poems, short stories and drawings, some of which were in the camp and some immediately after the return from Tambov and other camps in the Soviet Union. The focus is on the question of dealing with the thesis of the Auschwitz concentration camp survivor Viktor Frankl, psychiatrist and neurologist from Vienna, that the meaning of camp life - logotherapy - can have a self-healing effect and increase the self-healing powers, which increases the chances of survival.

This study looked at how using small or large pieces of Rice Husk Ash and Waste Paper Sludge Ash can affect how strong and how much the concrete shrinks when it dries. When Rice Husk Ash (RHA) and Waste Paper Sludge Ash (WPSA) were added to concrete, more water was needed. However, the mechanical properties of the concrete were similar or better than the concrete made with just Ordinary Portland Cement (OPC). Finer RHA and WPSA gave the best improvements. Rice husk and waste paper ash made things shrink a lot because of tiny particles that cause it to happen. This research looked at using waste paper sludge ash instead of some of the cement in a kind of concrete called M20 mix. They tested different amounts of the ash (0%, 5%, 10%, 15%, 20%, and 25%) to see how strong it made the concrete. They tested the strength of the concrete up to 28 days after it was made and compared it to normal concrete. Waste paper sludge can be used as fuel because it has a lot of heat energy. Afterwards, the remaining ash can be used to replace some of the cement.

We propose a unique form of dye-sensitized solar cells (DSSCs), paper DSSCs based on carbon-nanotube (CNT) composite papers, and the use of a gel electrolyte for the paper DSSC. In our previous study, we succeeded in developing the paper DSSC. However, its performance and lifetime were not sufficient. We considered that the problem was the use of liquid-type electrolyte. To improve the performance of the paper DSSC, a gel electrolyte was introduced to increase safety and durability. Here, a polymer gel electrolyte was synthesized using a copolymer of polyethylene glycol (PEG) and polyvinylidene fluoride (PVDF) as a matrix, mixed with iodine and potassium iodide. The resulting paper DSSC had a fill factor (FF, a performance indicator) of 0.248 and a conversion efficiency of 2.43 × 10−5% with an extended working time (lifetime) of more than 110 min. Further modifications were made to the metallic CNT composite paper and the gel electrolyte, resulting in an increased conversion efficiency of 2.02 × 10−3%. This study suggests the potential of gel electrolytes in enhancing the performance of paper DSSCs, providing new insights for their future applications.

The aim of this study is to propose a test method for the determination of the quality of transformer paper insulation. For this purpose, the oil/cellulose insulation systems were exposed to various accelerated aging tests. The results of the aging experiments of normal Kraft and thermally upgraded papers, two different types of transformer oil (mineral and natural ester), and copper are shown. Aging was carried out in various experiments at 150 °C, 160 °C, 170 °C, and 180 °C with dry (initial values ≤ 0.5%) and moistened cellulose insulation (initial values 3–3.5%). Following insulating oil and paper, degradation markers were measured: the degree of polymerization, tensile strength, furan derivates, methanol/ethanol, acidity, interfacial tension, and dissipation factor. It was found that the aging of cellulose insulation in cycles was 1.5–1.6 times faster in comparison to continuous aging, due to the more pronounced effect of hydrolytic mechanism in cyclic aging owing to the produced and absorbed water. Furthermore, it was observed that the high initial water content in cellulose increases the aging rate two to three times more than in the dry experimental setup. The proposed aging test in cycles can be used to achieve faster aging and to compare the quality of different insulating papers.

Microfluidic paper-based analytical devices (μPADs) are emerging as powerful analytical platforms in clinical diagnostics, food safety, and environmental protection because of their low cost and favorable substrate properties for biosensing. However, the existing top-down fabrication methods of paper-based chips suffer from low resolution (200 μm). Additionally, papers have limitations in their physical properties (e.g., thickness, transmittance, and mechanical flexibility). Here, we demonstrate a bottom-up approach for the rapid fabrication of heterogeneously controlled paper-based chip arrays. We simply print a wax-patterned microchip with wettability contrasts, enabling automatic and selective assembly of cellulose microfibers to construct predefined paper-based microchip arrays with controllable thickness. This paper-based microchip printing technology is feasible for various substrate materials ranging from inorganic glass to organic polymers, providing a versatile platform for the full range of applications including transparent devices and flexible health monitoring. Our bottom-up printing technology using cellulose microfibers as the starting material provides a lateral resolution down to 42 ± 3 μm and achieves the narrowest channel barrier down to 33 ± 2 μm. As a proof-of-concept demonstration, a flexible paper-based glucose monitor is built for human health care, requiring only 0.3 μL of sample for testing.

In the European Union (EU), Regulation (EC) 1935/2004 provides a harmonized legal EU framework and sets out the general principles for safety and inertness for all Food Contact Materials (FCMs) and Food Contact Articles. From a food safety point of view, however, specific EU legislation for paper and cardboard FCMs is lacking, while at Member State level, national legislation differs among countries. More than 11,000 chemicals have been identified in all types of FCMs, most of them without any information on toxicity or migration potential from FCM to food. The present review shows a wide variability of protocols, approaches, and conditions used in scientific studies, which are difficult to compare. In this regard, procedures and conditions laid down in EU legislation for plastics and European Standards (EN protocols) may serve as a good basis for the future sample preparation procedures in the framework of paper and cardboard FCMs safety assessment. Challenges on sample preparation procedures are presented involving the interlinked steps of sample preparation, conditions used and their impact in chemical analysis and in vitro bioassay testing.

Publisher Copyright: © 2022 Elsevier Ltd Laser-induced graphene from paper (paper-LIG) was applied in non-enzymatic electrochemical sensing of uric acid (UA) in human urine. Paper-LIG was formed by CO2 laser modification of paper into a 3D graphene arrangement. Kinetic analysis of paper-LIG electrodes returned effective heterogeneous electron transfer standard rate constants of 1.4 × 10−3 cm s−1 and 7.8 × 10−4 cm s−1 for [Ru(NH3)6]2+/3+ and [Fe(CN)6]4−/3− redox probes, respectively. These electrodes were able to detect and quantify uric acid in PBS within the 10–300 μM range at pH between 5.6 and 7.4. At pH 7.4, a linear response (R2 = 0.999) from 10 to 250 μM was achieved, with a limit of detection of 3.97 μM and a sensitivity of 0.363 μA cm−2 μM−1. Paper-LIG electrodes denoted adequate selectivity in synthetic urine as well as in ascorbic acid (AA) and dopamine (DA)-containing electrolytes. Determination of urinary UA content in human samples returned a concentration of c.a. 1.8–1.9 mM, within the range for healthy individuals. Recoveries of samples spiked with 50 and 100 μM UA were 100.6% and 95.4%, respectively, with satisfactory reproducibility and stability. These cheap, lightweight, flexible, and eco-friendly paper-LIG biosensors for non-enzymatic quantification of UA in human urine pave the way to widespread application in the detection of other important biomarkers. publishersversion published

In the European Union (EU), Regulation (EC) 1935/2004 provides a harmonized legal EU framework and sets out the general principles for safety and inertness for all Food Contact Materials (FCMs) and Food Contact Articles. From a food safety point of view, however, specific EU legislation for paper and cardboard FCMs is lacking, while at Member State level, national legislation differs among countries. More than 11,000 chemicals have been identified in all types of FCMs, most of them without any information on toxicity or migration potential from FCM to food. The present review shows a wide variability of protocols, approaches, and conditions used in scientific studies, which are difficult to compare. In this regard, procedures and conditions laid down in EU legislation for plastics and European Standards (EN protocols) may serve as a good basis for the future sample preparation procedures in the framework of paper and cardboard FCMs safety assessment. Challenges on sample preparation procedures are presented involving the interlinked steps of sample preparation, conditions used and their impact in chemical analysis and in vitro bioassay testing. Currently, there is no general consensus on the criteria for structuring, evaluating, and tuning sample preparation procedures for paper and cardboard FCMs. For this purpose, a set of modified criteria and a decision tree are proposed based on the literature. Along this, mass transfer processes occurring in paper and cardboard FCMs and parameters affecting chemical migration need to be accounted for prior to reaching general consensus on criteria for sample preparation procedures.

Businesses, which provide the production and mediation of goods and services needed by the society, are organizations that have goals such as growth, development, making profit, establishing a sustainable structure, and realizing social responsibility projects. It is important for businesses to have a financially strong structure in order to achieve their goals. In order to establish a sustainable financial structure, analyzes are carried out with various methods using the historical data of the enterprises and future decisions are taken with these analysis outputs. One of the financial sustainability measures for businesses is performance measurement. In many academic studies in the literature, it is observed that Multi-Criteria Decision Making (MCDM) methods are used for financial performance measurement. With MCDM methods, companies are compared financially within themselves, by years and with the sector. This study was carried out to measure the financial performance of businesses operating in the BIST Paper and Paper Products Printing Sector. As a sample, the data of 9 companies operating in the BIST Paper and Paper Products Printing Sector were used. The financial ratios of the enterprises for the years 2016-2021 were obtained and the analysis was carried out with COPRAS and MOORA, which are MCDM methods. Using two analysis methods provides the opportunity to evaluate financial performance rankings from different perspectives. As a result of the study, the financial performance rankings of 9 companies in the sector were evaluated according to both methods.

Paper is one of the most common wastes produced by humans, this paper waste is often found in household activities as well as offices and schools. Processing recycling of paper can add many advantages including being able to reduce waste in the environment, save energy, reduce the impact of global warming and can also generate income. This recycled paper can also be used to make various handicraft products that can be made by people who have creative values and an artistic spirit. The works of this recycled paper can be used as home decoration knick-knacks, stationery and office equipment, You can also make unique and creative multi-purpose containers that housewives can be interested in. Apart from that, they can be used for materials for student craft assignments as well as school students. Paper waste management certainly requires more attention, this can be overcome by efforts to reduce it by converting paper waste into recycled paper which has a selling value and is useful.

Microfibrillated cellulose (MFC) was prepared from post-consumer old corrugated container (OCC) material, which was first disintegrated in water, cleaned to remove impurities, and then fibrillated by grinding. Those processed MFCs were treated with in-situ formation of calcium carbonate by adding calcium oxide and injecting carbon dioxide into the mixture up to the ratio of 1:40 (MFC : calcium carbonate) by weight. The MFCs had a dark brown color initially but turned into high brightness materials similar to commercial ground calcium carbonate (GCC) after the in-situ formation process. The MFCs that had calcium carbonate attached on their surfaces, which were lengthy and flexible, were called flexible calcium carbonate from OCC (FCCO). Paper containing FCCO gave higher bulk, higher stiffness, and higher tensile index without lowering smoothness when compared to the paper containing commercial GCC. However, brightness was slightly lowered because of initial low brightness of the OCC. This study also demonstrated the feasibility to substitute wood fibers up to 5% with FCCO without lowering essential properties for printing paper. Benefits of the waste paper are savings of both wood resources and production cost.

Evidentiality refers to the speaker’s attitude towards the source of information and the reliability of the information conveyed and is one of the most important micro features of academic discourse. This study compared how Chinese and American researchers differed in the use of evidential verbs in their texts, the use of evidential verbs in 200 Chinese and American oil and gas experimental research papers is compared in this study using a combination of quantitative and qualitative methodologies based on a comparative corpus. It was found that both Chinese and American students were able to learn the evidential verbs of empirical research and use more appropriate language to describe the course of the experimental research and its results, but Chinese students used less verbs, particularly perceptual, cognitive, and verbal evidential verbs. Chinese scholars struggle to take ownership of discourse and tend to employ negative verbs less frequently and their essays use a more homogeneous vocabulary. These findings highlight some of the writing issues Chinese scholars encounter while writing papers in the English language; this paper analyzes these issues and offers suggestions for academic writing.

Compared to students in other countries, Japanese university students tend to sleep less. Because there are many individual differences in sleep habits, a specific intervention is not necessarily appropriate. In this study, the sleep habits of university students were investigated using a sleep diary during a semester. Participants were 13 undergraduates who completed sleep diaries for one consecutive week on three separate occasions during the semester. The results showed that university students' sleep habits could be divided into three groups. While one group had no subjective sleep disorders, the other two groups reported poor sleep quality and went to bed late: one of the group tended to wake up early and sleep shorter, and the rest woke up later. Changes in bedtime were observed throughout the semester. University students may try to cope with events during the semester by changing their bedtimes. This study revealed that time management that keeps bedtime ahead of schedule without shifting the wake-up time through the semester is important for students with sleep difficulty.

Bacterial nanocellulose (BNC), due to its inherent nanometric scale and strength properties, can be considered as a good candidate to be used in papermaking. This work explored the possibility of using it in the production of fine paper as a wet-end component and for the paper coating. Filler-containing handsheet production was performed with and without the presence of common additives typically used in the furnish of office papers. It was found that, under optimized conditions, BNC mechanically treated by high-pressure homogenization could improve all the evaluated paper properties (mechanical, optical and structural) without impairing the filler retention. However, paper strength was improved only to a small extent (increase in the tensile index of 8% for a filler content of ca. 27.5%). On the other hand, when used at the paper surface, remarkable improvements in the gamut area of >25% in comparison to the base paper and of >40% in comparison to only-starch coated papers were achieved for a formulation having 50% BNC and 50% of carboxymethylcellulose. Overall, the present results highlight the possibility of using BNC as a paper component, particularly when applied at the paper substrate as a coating agent aiming at improving printing quality., Fundacão para a Ciência e a Tecnologia (FCT), Portugal is acknowledged by SFRH/BDE/108095/2015 grant and Strategic Research Centre Project (UIDB/00102/2020).

Vrsta študij ugotavlja, da likovne dejavnosti prispevajo k razvoju različnega znanja in spretnosti. Študij, ki bi empirično preverjale in dokazovale tovrstno napredovanje, je sicer manj, kar je tudi eden od razlogov udejanjanja naše raziskave. Pestrost likovnih dejavnosti je povezana z različnimi vrstami veščin, zato smo raziskovanje omejili na enega od najpogosteje uporabljanih materialov v predšolskem obdobju, tj. papir. Otroci se v vrtcu vsakodnevno srečujejo in rokujejo s papirjem. Z razvojem fine motorike otroci usvojijo prstne spretnosti, ki so potrebne za obdelavo papirja. To so mečkanje, pregibanje, trganje in uporaba orodij za obdelovanje papirja (škarje in šablona ali ravnilo) (Kurikulum za vrtce, 1999). Nekoliko kasneje k razvijanju drobnih gibov prispeva tudi rezanje in oblikovanje majhnih koščkov papirja. Pri tem imajo pomembno vlogo izkušnje in vaja. Slednja je najučinkovitejša, če je zasnovana v obliki igre. Papir so iz rastlinskih vlaken izdelovali že stari Kitajci, v Evropi pa ga poznamo od 9. stoletja naprej. Papir pridobivajo pretežno iz rastlinskih vlaken, katerim očistijo necelulozne sestavine. Uporaba papirja v likovnih delih je bolj vsestranska, kot si morda mislimo (Čadež-Lapajne, 1983). Vsaka likovna tehnika potrebuje primerno vrsto papirja. Seveda je pri tem pomembnih več lastnosti, od vpojnosti, gramature, pa vse do videza in teksture. Pred uporabo je pomembno, da poznamo osnovne značilnosti papirja. Pri nekaterih likovnih tehnikah pomembno vlogo igra tudi potek vlaken. To vpliva na zgibanje, trganje, rezanje in tudi zvijanje (Brodek, 2013). Akvarelni papir, recikliran papir, papir za origamije in prosojni papir so le nekatere vrste papirja, ki se med seboj precej razlikujejo. V vrtcu so sprva bolj prisotne preproste tehnike obdelovanja papirja, s katerimi razvijamo soročne spretnosti, kot so: mečkanje, trganje, gubanje in pregibanje, kasneje pa tudi rezanje, in lepljenje ter celo prebadanje, luknjanje in spenjanje. Pri rezanju, lepljenju, luknjanju in spenjanju za obdelavo potrebujemo orodja, medtem ko ostale tehnike izvajamo brez orodij. V vrtcu največkrat uporabljamo otroške škarje, škarje z vzorcem, luknjač, spenjač in različna ravnila oziroma šablone (Milčinovič, 1997). Otroške škarje se razlikujejo po velikosti, obliki držala, barvi, dolžini in obliki rezil (imajo zaobljeno rezilo), lahko so desnoročne ali levoročne, nekatere imajo pomagalo za odpiranje škarij, ki olajšajo uporabo. Otroci v vrtcu ravnila uporabljajo redkeje. Poleg klasičnega ravnila poznamo še trikotna ravnila in ravnila krivih oblik za risanje krivih črt. Če imajo ravnila na podlagi prazne prostore, namenjene risanju različnih likov in oblik, jim pravimo šablone. Pri risanju črt z ravnilom je pomembno, da držimo konico svinčnika tik ob stranici ravnila. Ta mora biti nagnjena v smeri, kamor vlečemo črto (Fošnarič, Slukan, Virtič, Puncer, 2004). S pomočjo luknjača v papirnatih gradivih izsekamo odprtino. Poznamo luknjače, s katerimi s pomočjo kladiva na trdi podlagi izsekamo luknjo, in tiste, ki so avtomatski (prav tam). Izbira spenjača je odvisna od števila listov papirja, ki jih želimo naenkrat speti. Namizni pisarniški spenjači lahko spnejo od 2 do 50 listov. Tudi ročni spenjači ali spenjalne klešče spnejo od 2 do 40 listov. Več listov pa lahko spnejo električni spenjači. Za odstranjevanje sponk iz spetega gradiva pa uporabljamo razpenjač. A number of studies have found that art activities contribute to the development of different skills. There are fewer studies that empirically test and prove this kind of progression, which is one of the reasons I decided to investigate it. The variety of art activities is linked to different types of skills, so I have limited my research to one of the most commonly used materials in the preschool period, i.e. paper. Children in kindergarten encounter and handle paper on a daily basis. As children develop fine motor skills, they acquire the finger skills necessary for working with paper: creasing, folding, tearing and the use of paper tools (scissors and a jig or ruler) (Kindergarten Curriculum, 1999). A little later, cutting and shaping small pieces of paper also contributes to the development of fine motor skills (Curriculum for Kindergarten, 1999). Experience and practice play an important role here. The latter is most effective if it is designed in the form of a game. Paper was made from plant fibres by the ancient Chinese and has been known in Europe since the 9th century. Paper is mainly made from plant fibres, which are stripped of their non-cellulosic components. The use of paper in fine art is more versatile than we might think (Čadež-Lapanje, 1983). Each artistic technique needs a suitable type of paper. Of course, several properties are important, from absorbency, grammage, to appearance and texture. Before using it, it is important to know the basic characteristics of the paper. In some fine art techniques, the fibre course also plays an important role. This influences folding, tearing, cutting and even curling (Brodek, 2013). Watercolour paper, recycled paper, origami paper and transparency paper are just some of the types of paper that differ considerably from each other. In kindergarten, simple papermaking techniques are more prevalent at first, which helps us develop related skills such as creasing, tearing, folding and creasing. Later, we develop cutting, gluing and even punching, hole-punching and stapling.Cutting, gluing, punching and stapling require tools, while the other techniques are carried out without tools. In kindergarten, children's scissors, pattern scissors, hole punch, stapler and various rulers or stencils are most commonly used (Milčinovič, 1997). Children's scissors vary in size, shape of handle, colour, length and shape of blades (they have a rounded blade). They can be right-handed or left-handed, and some have a scissor opening aid to make them easier to use. Rulers are less frequently used by children in kindergarten. Beside classic ruler, we also know triangular rulers and curved rulers for drawing curved lines. If rulers have blank spaces on the base for drawing different shapes and figures, they are called stencils. When drawing lines with a ruler, it is important to hold the tip of the pencil right against the side of the ruler. This should be inclined in the direction where the line is drawn (Fošnarič, Slukan, Virtič, Puncer 2004). Using a hole punch helps us to cut an opening in paper materials. There are punches that use a hammer to punch a hole in a hard substrate and those that are automatic (ibid.). The choice of stapler depends on the number of sheets of paper to be stapled at one time. Desktop office staplers can staple from 2 to 50 sheets. Manual staplers or staplers can also staple from 2 to 40 sheets. Electric staplers can staple more sheets. Paper clip remover are used to remove staples from stapled material.

Developing a convenient detection method for dopamine holds a significant incentive due to its high clinical significance. Herein, we synthesize crystalline MnOOH nanowires (MNWs) via a simple solvothermal treatment of KMnO4 and demonstrate that they possess excellent oxidase-like activity owing to the presence of pure Mn3+ sites on the MNWs. Particularly, MNWs catalyze the rapid oxidation of dopamine into aminochromes, which show a vivid brown color. The dopamine oxidase-like activity of MNWs follows the typical Michaelis–Mentenkinetics with excellent storage stability. Based on the affirmative catalytic features, a paper dipstick incorporating MNWs in the detection zone is constructed for the one-step colorimetric detection of target dopamine. By immersing the dipstick into the sample solution for 30 min, the sample spontaneously moves to the detection zone due to capillary force, yielding a brown color proportional to the amount of dopamine, which is quantified from an image acquired using a smartphone. With the MNW-containing solution-based assay and MNW-incorporated paper dipstick, dopamine is successfully determined with high selectivity, sensitivity, and detection precision when using spiked human serum and pharmaceutical dopamine injection samples, respectively. Successful analytical values such as the dynamic linear ranges of 3–60 μM and 0.05–7 mM are achieved with the solution-based assay and paper dipstick, respectively, along with excellent detection accuracy (95–99%) and precision (1.0–3.1%). Hence, we developed a simple and efficient nanozyme-based paper dipstick biosensor for dopamine that can be used in point-of-care testing environments.

The reliability and performance of technological equipment largely depends on timely and reliable diagnostics of less durable assembly units, which include rolling bearings. An effective tool for determining state of the mechanical rotational systems on rolling bearings is vibration diagnostics. The variety vibration diagnostic method which are used on practise is due to the complexity extracting an informative component for estimation and predicting the state of rolling bearings from the general vibration signal of the study unit. The article is dedicated information content study of narrow frequency ranges of the vibration signal operation bearing assemblies paper machines and their use as diagnostic parameters for vibration diagnostics of rolling bearings. The paper presents the analysis results of vibration diagnostics existing methods of bearing assemblies of the technological equipment and establishes the determination defects in rolling bearings by changing the vibration level on the characteristic frequencies components of the vibration spectrum and the bypass spectrum provides more specific information about the nature damage of the bearing and its operation. On the processing experimental data base i.e. the average vibration velocity spectra signal taken from the bearing assembly paper machine, we offer a relative indicator for current state bearing estimation and its state prediction progress, which helps to make a decision on the suitability or unsuitability bearing, Надійність та продуктивність роботи технологічного обладнання значною мірою залежить від вчасної і надійної діагностики найменш довговічних складальних одиниць, до яких належать підшипники кочення. Ефективним інструментом визначення стану механічних обертових систем на підшипниках кочення є вібраційна діагностика. Різноманітність методів вібродіагностики, що застосовуються на практиці, обумовлена складністю виділення інформативної складової для оцінки і прогнозування стану підшипників кочення із загального вібраційного сигналу досліджуваного вузла. Стаття присвячена дослідженню інформативності вузьких діапазонів частот вібраційного сигналу роботи підшипникових вузлів папероробних машин та їх застосуванню як діагностичних параметрів для вібродіагностики підшипників кочення. У роботі наведено результати аналізу існуючих методів вібродіагностики підшипникових вузлів технологічного обладнання та встановлено, що визначення дефектів підшипників кочення за зміною рівня вібрацій на характерних частотах складових спектра вібрації та спектра обвідної надає більш конкретну інформацію щодо характеру пошкодження підшипника та його експлуатації. На підставі обробки експериментальних даних ‒ усереднених спектрів віброшвидкості сигналу, знятого з підшипникового вузла папероробної машини, – запропоновано відносний показник оцінки поточного стану підшипника та прогнозу розвитку його стану, з визначенням якого є можливість винесення рішення про придатність чи непридатність підшипника.

The aim of this white paper is to draw attention to the roles and responsibilities of higher education and research organisations in addressing gender-based violence. These roles and responsibilities may not be recognised or are downplayed, and this results in institutions failing to take appropriate action to ensure safe environments for students and staff. Secondly, the white paper aims to explicate the essential features and elements of effective policies and actions and lastly, to highlight the critical role of institutional leadership in making the policy frameworks and actions work. This white paper is primarily intended for: institutional leaders and top management; staff responsible for the design, adoption and implementation of institutional policies; staff appointed to support victims and survivors; and any other member of the academic community committed to ending gender-based violence. It builds on the results of the UniSAFE research, including the prevalence study (Lipinsky et al. 2022, Humbert et al. 2022), the institutional policy analysis (Huck et al. 2022), case studies (Ranea-Triviño et al. 2022), interviews (Blazyte and Pilinkaite 2022), and stakeholder and expert workshops (Yellow Window 2023a, 2023b), the purpose of which have been to gain insight into and test emerging policy solutions.

In the last two decades computer-based assessment has become an important part in support of teaching and learning. It is seen as a solution to implement assessment for learning in school and provide immediate feedback on students’ performance in real-time. Research literature on computer-based assessment suggests that every measurement instrument developer before implementation of a test has to provide evidence that computer-based and paper-based versions are equivalent and provide consistent measures. There is a risk that properties of computer-based assessment including unfamiliarity with the system and proficiency level of digital skills can seriously affect students’ performance. This paper focuses on computer-based diagnostic assessment system designed to support numeracy and literacy teaching and learning. The aim of this study is to confirm that literacy and numeracy learning measurement instruments elaborated in diagnostic assessment system provide consistent results as paper-based versions of both instruments. Data were collected administering four tests. Two of the assessments were computer-based literacy and numeracy diagnostic assessments and two were paper-based versions. By analyzing both versions of assessments using various statistical techniques we explore differences in students’ performance. Our results showed that at this development phase of the computer-based diagnostic assessment system the students who completed computer-based test versions showed similar or better performance than their counterparts who completed paper-based versions.
