The eighteenth century books from the collection of the old digital library of the Library University Seville are analyzed to locate the parts made with decorated papers, in order to classify and describe them according to the proposals of specialized literature. For this, the records included in the repository of the digital collection are recovered, the digital reproductions of the books are visualized, the parts with decorated papers are identified and described following the decorated papers classification model, previously elaborated, based on the research of Professor Carpallo Bautista. The model is made up of 6 techniques and their variants. Of the more than 6.700 records from the 18th century in the collection of the digital ancient collection, 511 include decorated papers in their bindings. [ABSTRACT FROM AUTHOR]

Amate (amatl) is a handmade paper of Mexico made by Otomi Indians. This craft is made from bark of tree bark amate or jonote. It is originally developed in the states of Puebla, Hidalgo and Veracruz especially in San Pablito, Puebla. However, amate paper is sold as background Nahua paintings by artists from the state of Guerrero. Amate paper paintings are a combination of Nahua and Otomi traditions. While there have been some minor innovations, the amate paper is still done with the same basic process used in the pre-Hispanic period by obtaining a classical amate tree bark fiber. This is negatively affecting the ecosystem of the North of Puebla and forcing vendors bark in search of other species, so it is necessary to make paper amate more sustainably, including new types of bark from other species and by-products of agro-industries such as rice, coffee sugar cane, and other types of fiber that have highavailability The objective of this work was to analyze and compare the Chemical pulp of coffee characteristics, as raw material for amate paper of higher quality than that produced from the bark of other species. The results showed that the structural and chemical characteristics of coffee pulp cellulose pulp showed ease of paper making, due to its properties of adherence, formation and agglutination of fibers similar to the high quality of the final product as the amate tree bark-derived paper.

Democracy is considered to be the ideal foundation of societies today. In a democratic society, news media play a highly relevant role as avenues by which public and political powers can interact with society and facilitate civic participation. The public’s perception of the news media’s reputation is a crucial factor for enhancing trust and citizen engagement. This article presents a study of the reputation of the media (paper press, digital press, radio and television) in ten European countries: Austria, Belgium, France, Germany, Italy, Poland, Portugal, Romania, Sweden, and the United Kingdom. A quantitative method was applied to the results of a survey conducted to determine the reputation of news media among a sample of the informed population in those countries (1,000 residents of legal age who used media at least two or three times a week). The concept of reputation is thereby characterized in its association with the media, identifying its integrating attributes and assessing its incidence in each type of medium. The results indicate that, although television is the most widely used medium, the printed press enjoys a higher reputation in most of the countries studied, being seen as having the attributes of credibility and informative rigor. This study provides a detailed analysis of the scores given to media reputation attributes in the considered countries. It also offers a ranking of the media with the highest reputation in the countries examined, as well as a description of the reputational position of each medium. [ABSTRACT FROM AUTHOR]

The objective of the research was to analyze the role of machine data learning in systematic literature reviews. The Natural Language Processing technique called topic modeling was applied to a set of titles and abstracts collected from the Scopus database. Specifically, the Latent Dirichlet Assignment (LDA) technique was used, from which it was possible to discover and understand the underlying themes in the collection of documents. The results showed the usefulness of the technique used in the exploratory literature review, by allowing the results to be grouped by theme. Likewise, it was possible to identify the specific areas and activities where machine learning has been applied the most, in relation to literature reviews. It is concluded that the LDA technique is an easy-to-use strategy and whose results allow a wide collection of documents to be approached in a systematic and coherent manner, notably reducing the review time.

The psychometric properties of the Argentinian version of the ASSIST and its factorial invariance for two administration formats (paper-pencil and online), were analyzed. Two samples were employed. In one of them, the participants (n=700) completed the ASSIST in paper and pencil format, and in the other (n=835), they responded online. The model fit for both samples was tested obtaining adequate indices. A factorial invariance analysis then compared the model for the two administration formats, verifying adequate metric invariance. Furthermore, the internal consistency of the instrument dimensions for each sample was analyzed and compared. Results showed good coefficients. Finally, the comparison of dimension scores between the samples did not produce variations. The results and their practical implications are discussed. [ABSTRACT FROM AUTHOR]

The objective of this work was to verify the potentiality from the pulps to the soda-antraquinona of pine for the production of papers wave, liner and newspaper (blended with trash pulp), using adapted technological outlines of one manufactures of trash pulps. The work was carried out with pine chips coming from the north area of Missions, according to a prosecution indicated by Tucumán paper mill. In the case of liner and wave, the reached yield was of 67 % and the results indicated that the used process (soda-AQ of pine, with impregnation of 25 % of the chips) it is adapted for the obtaining of pulp brown semichemical. The obtained pulp presented a quality more than enough to be used in the production of papers liner, being in the inferior limit of quality for the production of papers wave (130 g/m², RCT 1,56 kN/m, CMT 172 N). with regard to the periodic paper, the pulp with yield of 61 % was refined blended with trash pulp in different proportions and it was whitened with NaClO with an objective target of 70 %ISO. The best mixture was that of 90% of trash pulp and 10 % of pulp pine semichemical. [ABSTRACT FROM AUTHOR]

Paper machines consume large amounts of energy and in most cases savings are possible. The drying section in the paper machine has been structurally modified through 60 years of operation, with limited use of the heat recovery system. The objective of the work is to assess the opportunities for energy conservation, through the application of energy management systems in the paper factory.Methodologies are applied for energy balance and heat integration, taking into account the requirements specified by the Cuban standard ISO 50001 for energy management systems in terms of energy review. Pinch analysis is applied using HENSAD and Aspen Energy Analyzer computing resources. The proposed energy performance indicators constitute a reference for the definition of an energy baseline. Energy conservation opportunities are identified with a total annual saving of $ 48,902 that makes it feasible to execute a project of $ 35 546, whose capital cost is estimated to be recovered in 2 years.

Antecedentes: la producción de papel está soportada principalmente en la madera debido a su alto contenido de celulosa. Sin embargo, actualmente se buscan fuentes alternativas que desestimulen el uso de este recurso favoreciendo la protección de los recursos naturales. La producción de cacao es una actividad económica importante en Colombia, sin embargo, genera grandes cantidades de residuos orgánicos. La cascarilla de cacao es uno de los residuos más significativos de la industria del cacao y representa alrededor del 12 % del peso total de la semilla. Objetivo: evaluar las propiedades fisicoquímicas del papel obtenido a partir de la cascarilla de cacao de la variedad TCS 01. Métodos: se identificó y cuantificó la composición de celulosa, hemicelulosa y lignina de la cascarilla de cacao. Se realizó un diseño experimental para analizar las condiciones de extracción y elaboración del papel obtenido de la celulosa de la cascarilla y se evaluaron seis parámetros de calidad basado en la norma NTC 5342 (muestreo para determinar la calidad de papel y cartón): adsorción, tensión, escritura, color, textura y apariencia. Resultados: se obtuvo un porcentaje de celulosa, hemicelulosa y lignina de 12,5, 21,5 y 15,6 % en peso respectivamente. A partir del diseño experimental para la elaboración del papel, se observó que a una temperatura de 80°C y durante 8 horas se obtuvo el mejor tratamiento, mostrando las mejores características de calidad y cumpliendo lo requerido por la NTC 5342. Se observó que la masa límite de celulosa fue de 4,21 g de muestra húmeda la cual tuvo una absorción de 3,5 ml de agua. Los ensayos de tensión mostraron resultados de 8,2 N en las muestras de papel. Conclusiones: aunque el material obtenido no cumple a cabalidad con las características necesarias para catalogarse como papel, este material puede ser utilizado en la producción de envases y embalajes donde se requiere resistencia mecánica moderada o en la producción del material llamado “cartón paja”. Además, su alta adsorción medida en la prueba realizada indica que este material podría ser utilizado como absorbente en las industrias alimentaria o de construcción. [ABSTRACT FROM AUTHOR]

This paper evaluates economically build a new cogeneration plant with clean energy from forest biomass company Norske Skog Bio Bio (NSBB). This is to show that this plant-based forest biomass for electricity generation is a viable option in Chile from the economic and environmental perspective. For this evaluation, we propose an approach that uses “real options theory" based on the application of log-transformed binomial method with six steps. Also, comparing the results obtained with this approach, the results using traditional methods. It is found that for all cases studied, the value yielded by the real options method was higher than estimated by traditional methods. It is concluded that this alternative profitable investment.

This research study proposes a classification system to identify and prevent occupational accidents in fiber storage warehouses at a pulp and paper facility. The present analysis is based on variables including pedestrian circulation, bobcat, trailer trucks, access, pedestrian circulation zones, and handrails. The proposed methodology defines and trains the system by using occupational accident event data collected at the facility. Three different predicting algorithms are used: J48 decision-making trees, Naive Bayes, and Bayesian nets. The results show that the J48 decision-making tree algorithm accurately identifies possible occupational accidents 90% of the time. It is concluded that identifying variables involved in occupational accidents allows generating a C4.5 (J48) decision-making tree that can be used as a support tool to prevent occupational accidents.

In 1848 Dr. Castro Madriz issued the decree which established the Republic of Costa Rica and its new coinage. An oak tree (Quercus sp.) was engraved on silver coins as a symbol of the strength and hospitality of the new Republic. These coins were minted between 1850 and 1862 (1/4, 1/8 and 1/16 of Peso) and between 1864 and 1875 (50, 25, 10, and 5 cents of Peso). This paper provides information on the significance of the oak tree in the socio-political context of mid XIX century Costa Rica. It also provides estimates of the number of pieces minted of each value for a total of approximately 1.871.000 coins. The quarter Pesos of 1853 and 1855 are scarce while the 50 cents of 1875 are relatively common, and all denominations with little wear are rare. The Q. salicifolia tree is similar to that engraved on the coins. After 1880 an oak branch was engraved in different issues of paper money, mainly as a crown for the head of Liberty. The last bill with this symbol was issued in 1943, with a value of 1 colón. [ABSTRACT FROM AUTHOR]

This paper shows the methodology and results of the evaluation of the cleaning system of a Kraft paper mill. This evaluation was made keeping in mind variables of that system such as the pulp stock consistency percentage, ash content, air level in the pulp stock, and differential of pressure through the cleaners, for the analysis of a series of samplings carried out during the production of the different paper grades. On the basis of the results, possible modifications or improvements of the cleaning system were proposed, which will allow a reduction in pulp and water losses, energy consumption, and the amount of air required in the paper machine.
