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.

Research paper publication has a well defined process that is framed in the context of academic activity; the refusal to publish the research paper is an academic work rejection that can lead the researcher to academic duel, condition that the researcher must overcome soon. [ABSTRACT FROM AUTHOR]

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.

This study analyzed feasibility of manufacture of composite particleboards resinated with a mixture of phenol.formaldehyde resin and 4,4Œ-methylenediphenyl isocyanate in the weight ratio 70:30. For this purpose 3-layer particleboards were produced with varying shares of Kraft scrap paper pulp in the core. Experimental boards were manufactured applying 0, 10, 15, 25, 50 and 75% substitution of wood chips with Kraft paper pulp. Analyses were conducted to determine physico-mechanical properties of boards, i.e. bending strength, modulus of elasticity, internal bond before and after the boiling test and swelling in thickness after 24 soaking in water. Based on recorded testing results it was stated that moisture resistant composite boards manufactured with a 25% substitution of wood chips with Kraft paper pulp meet the requirements of the EN 312 standard for boards used in humid conditions in terms of their strength and moisture resistance specified in the internal bond after the boiling test.

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.

In 2009, the Colombian Constitutional Court issued ruling Auto 004, declaring 34 indigenous groups as being at risk of extermination due to the internal armed conflict and ordered the Colombian government, led by the Interior Ministry, to protect them. Since then, although the critical situation persists, the government has proven its compliance with the Court's order through a documentation process. The purpose of this article is to examine the role of documentation in mediating legal protection in a violent context. Based on yearlong participant observation at the Colombian Interior Ministry, the study approaches the production of the government's documentary response as an artifact. It addresses its formulation and context within the institutional setting, the discussions regarding what to include and what to exclude, and the decisions that shape its content. It highlights how the assembled document enchants, by skillfully combining the aesthetics and technical aspects. It illustrates how numbers that portray compliance are constructed and displayed in the document, while concealing the failure to make the changes that were ordered: a phenomenon termed here as complying incompliantly. The paper's originality lies in deconstructing the powerful governmental sophism of money invested as compliance with an obligation, through ethnographic attention to the document. Likewise, the analysis is part of the challenge dealt with by studies of the gap between law and reality, by suggesting that the problem lies not in a gap between well-intended law and the violent reality that overflows it but rather in the way this "gap" is filled by complex documenting processes. As such, the paper contributes to the anthropological studies on law, documentation and accountability. [ABSTRACT FROM AUTHOR]

Within the pharmaceutical policies, the State has been interested in the medical prescription as a legal document of prescription and dispensing medicines and health products contributing to the improvement in patient safety. To measure the degree of compliance of the prescriptions that arrive at the community pharmacy, a cross-sectional observational study was conducted for two months of 2019 to review all the prescriptions on paper presented for dispensing in five pharmacies. Within this period, a total of 33463 prescriptions were received 30085 (89.90%) were electronic and 3378 (10.10%) were on paper. Of these, 841 (25%) came from the public health system, 931 (27%) from MUFACE, 362 (11%) from ISFAS, 28 (1%) from MUGEJU, 201 (6%) other organizations and 1015 (30%) from private healthcare. When the number and percentage of paper prescriptions that could be legally dispensed was analysed, it was observed that only 130 (65%) prescriptions of other organizations, 30 (4%) of the public health system and 34 (3%) of private healthcare were correctly completed. Therefore, only 194 of the 3,378 paper prescriptions (6%) received during two months in the five community pharmacies could be dispensed according to current law. When the prescriptions are not correctly filled, with the mandatory basic data, indispensable for the validity of the medical prescription, the patient's safety can be compromised and the prescribing health professionals and those who dispense the medications are exposed to sanctions.

In this paper we present a classification of sources and the strategies used by writers of theses and research papers in order to identify a research gap in Humanities. Based both on a qualitative study and a corpus analysis, we aim to determine the variation of such communicative act (identifying a research gap) in theses and research papers in the Humanities. The results show that identifying a research gap is carried out in both genres, though it is more frequent in the theses, possibly due to its evaluative nature. Thus, regardless the genre, it is easy to present an own research gap (without the reference to other sources). Finally, data show that specific strategies for identifying a research gap in the Humanities are not the same in both genres that are analyzed. [ABSTRACT FROM AUTHOR]

The content of the 847 papers presented by authors from Spanish universities at the six conferences of the Spanish Association for Communication Research (AE-IC) is analyzed. The six conferences were held in Santiago de Compostela (2008), Malaga (2010), Tarragona (2012), Bilbao (2014), Madrid (2016), and Salamanca (2018). The research variables of study are: author's profiles, geographic location, gender, home university, most commonly studied topics, and considered media. The results confirm that the gender divide no longer exist: in fact, there are more female than male authors. Universidad Complutense de Madrid and Universitat Autònoma de Barcelona exhibit the highest rates of participation, and Madrid and Catalonia are the most active regions, followed by Andalusia and Valencia. The topics treated are quite diverse, with the study of media content standing out, mainly those focused on political communication. Other common topics are the impact of the digital age, and audiovisual media structure. [ABSTRACT FROM AUTHOR]

The research and development of new products that could partially or completely replace raw materials used for energy production, high value-added chemical products, and even the production of paper, has allowed industrial hemp (Cannabis sativa L.) to become the main raw material for the reactivation of a bio-based economy with high production conditions and capacities. Based on this, the objective of this research is to deepen on the potential use of hemp fiber in the paper industry, supported by studies carried out by the Colombian State regarding the availability of forest crops for commercial purposes, which are basically used for planting and the production of wood resources such as pine and eucalyptus. It has been considered important to demonstrate that hemp, as a source of primary production, provides competitive economic, environmental, and social advantages over traditional crops, even for new sources of bio-based research.

Most of the national and international documentary heritage are on paper. From industrialization in the manufacture of such material, paper with acidity levels has been produced which, together with other factors, has been causing the deterioration of this type of documentary heritage. In recent decades, with the incorporation of new paper production processes this problem has been partly solved. The international standards organism ISO has drafted two rules in this connection: ISO 9706 and ISO 11108. With the spread and recommendation for the use of permanent paper for preservation of documentary heritage in the long term, it is essential to know the standards and be well informed. This article describes the variables in the manufacture of paper that influence the permanence of the papers. It also identifies the concepts and history that surround both ISO standards and the main characteristics and component parts of them. The annex provides a glossary of key technical terms used.

The use of varnishes as a final coat in graphic work fulfills an aesthetic and protective function. Over time, or due to adverse conditions, these varnishes undergo a series of degradations in their color that can distort the original appearance of the underlying work. Knowing the chromatic variations of these materials is essential for their selection as a conservation varnish. This work collects the results obtained from the colorimetric study carried out on a series of samples of paper with varnish exposing to different physical-chemical tests (humidity, immersion in water, dry heat and accelerated aging) tests that recreate adverse conditions to which this type of woks may be exposed as a consequence of its natural aging, the action of certain degradation factors or the restorative action. For this purpose, Somerset 100% cotton paper has been selected, which has been applied different varnishes of traditional use in graphic works: shellac, gum arabic, egg white, rosin and dammar. The color of these samples has been studied following the CIEL*a*b* 1976 system, calculating the colorimetric differences from the comparison between the reference samples and the samples after the physical-chemical tests.
