El bisfenol A (BPA) es un monómero empleado en la fabricación de policarbonato y resinas epoxi por lo cual es fabricado extensivamente a nivel mundial. No obstante, el BPA tiene un aspecto poco deseado ya que diversos estudios lo relacionan con distintas enfermedades especialmente por su efecto como disruptor endocrino. Actualmente el BPA es tema de controversia entre comunidades científicas y agentes gubernamentales, específicamente en relación a su ingesta diaria admisible (IDA). Por otra parte, los tickets de papel térmico son agentes de contaminación en plantas de reciclaje de papel, en consecuencia desde el Laboratorio de Química Industrial (LQI) se empleó la extracción Soxhlet con solventes orgánicos con el fin de eliminar BPA contaminante en muestras de papel térmico usado.

The article analyzes the speech of the Zig-Zag magazine in relation to the city of Arica, as a collaborator in a propaganda policy of Chileanization, in the context in which Peru and Chile must prepare for the Treaty that will resolve the geopolitical and sovereignty conflict over the cities of Tacna and Arica. From this perspective, the research question is: How do the reproduction and dissemination of the Zig-Zag's photographs collaborate, and what lies behind the news regarding the city of Arica between 1910 and 1930 in the construction of the Chileanizing discourse? From this city? In this line the news and photographic images of the Zig-Zag magazine referring to the city of Arica, referred to a systematic violence towards the Peruvian population of the area, focused on the invisibility of the original inhabitants and the negative and derogatory language towards the Peruvians. Granting an exorbitant relevance: to the actions of the Chilean State in the area, to the objectivity and rationality of its political authorities to resolve the conflict with Peru, and to repeatedly expose the Chilean army as the greatest military force prepared in Latin America.

A biosimilar (BS) is a biological drug that contains a version of the active substance of an already authorized original biological product. The BSs are marketed after patent period of the original drug has ended and once it has been demonstrated that the differences regarding the innovative medicine have no relevant effect on its safety or clinical efficacy. The Spanish Society of Rheumatology, in line with the European Medicines Agency, considers that because of its nature and complexity of production, a BS cannot be considered to be the same as a generic drug. The Spanish Society of Rheumatology expresses an unequivocal commitment to the sustainability of the health system in our country and our steadfast alignment with all measures designed to ensure continuity, without reducing the quality of care. Therefore, we believe that the advent of BSs will likely facilitate access of patients with rheumatic diseases to the biological drugs. This article reviews the European Medicines Agency requirements for authorization, the Spanish legal framework and controversies on BS and presents the position paper of the Spanish Society of Rheumatology on these drugs.

The process of convergence with the European Higher Education Area led to the publication of the White Paper on the qualification of the Degree in Psychology (ANECA, 2005) in which an extensive analysis was carried out of the situation of university studies in psychology in Spain and guidelines were produced to adapt the degree to the European requirements. Ten years later, the present paper aims to analyze the implementation rate of the guidelines included in the White Paper, as well as to develop prognostic models based on the trends observed using time series analyses. The results show a constant and progressive increase in the educational training offered, the number of new faculties, and other closely associated indicators related to this growth. Different explanations and reasons for these results are discussed. We also reflect on the detrimental impact on job security amongst psychologists, the high unemployment rates, and the negative consequences for a sustainable model of professional development.

The objective of this paper is to provide the physical bases that allow more accurate diagnosis of the conditions of paper machines for better maintenance. The diagnostic of the mechanical condition of press felts and rolls in the press section of paper machines using the classical vibration analysis is complex, so maintenance of these elements is done in a preventive and not predictive way. In this work a mathematical model that describes the dynamic behavior of the presses in paper machines is developed. Through numerical simulations, the motion equation of the proposed model is solved and compared with measurements done in industrial machines. It is concluded that the proposed model properly describes the vibratory behavior of presses and provides the vibratory symptoms that allow the diagnosis of the problems that they may have.

This article presents the results of a research in the classroom in the subject Programming I, initial course of computer programming in Systems Engineering and Computing. The research pretend to approach the impact of two methodologies of problem solving based on programming logic and the use of programming languages for its implementation. We use a qualitative perspective, as far as the students' performance as programmers, and quantitative, in what corresponds to the qualification of the written evaluations. It has been used to structure two parallel courses, using different methodologies for solving programming problems. With the first group, a methodology was implemented based on the conceptual resolution of these problems using solutions on paper and with the other one we use resolution of problems based on the intensive use of the computer. The results show a very interesting trend that allows us to make some important inferences regarding the promotion of logic and the approach of solutions in the paper against the use of the computer and the deepening in the purely technological knowledge. Conclusions leave open doors of the discussion about the different and possible ways that the students of programming to appropriate, assimilate and apply the own knowledge of this area.

The article reflects on the monetary and economic history during the independence of Peru taking place between 1820 and 1823. The imperial money system, the Auxiliary Bank of Paper Money in Peru and Peruvian president José de San Martín's influence on these systems are discussed by the author. The traditional Spanish monetary system, its policies and its influences on Peru's monetary system are addressed. The paradox of the money shortages in Peru during José de San Martin's protectorate are described by the author as machines without money.

In the digital age the ways of reading have experienced transformations that alter traditional dynamics and coordinates of space and time. For more than five hundred years the written language- printed and linear- has been characteristically at the epicenter of knowledge, leaving in a subordinate position other ways of acquiring knowledge. This paper describes the characteristics of digital reading, that establishes a first step toward a grammar of digital reading. Further, those characteristics are defined through cognitive, haptics and hipertextual issues. This paper emphasizes how screen reading does not aspire to compete with traditional reading because the past and present can be conjugated in new forms of cultural hybridizations. It also outlines an overview of the role of reading in the transmedia narrative. Understanding the aspects that interest the nature of digital reading is one of the ways to move forward with critical knowledge in virtual scenarios that offer us new possibilities of creation and access to knowledge.

In recent years, experts from around the world have warned that printed newspapers may disappear in the medium term. In some cases, even specific dates were given. The proliferation of digital media and the paradigma shift in our society are usually mentioned among the causes of this disappearance, especially when it comes to the media. Focusing particularly on theSpanish case, this paper offers an alternative vision, providing evidence that it's not the first time a possible disappearance of printed newspapers is being discussed, that the Internet isn't the main reason for the crisis hitting the sector, and that newspapers aren't facing the worst crisis in thirty years. Although both printed newspapers and printed books could disappear in a still distant future, no concluding evidence points in that direction and this kind of statements are not to be recommended.

This article presents the papers which, before Medellin, and together with the opening discourse of Paul VI, marked the course of the Second Conference and exposed: the reality of the poor and believing people, the listening to their cry, the discernment of the signs of the times, and pastoral options. Medellin was a creative reception of Vatican II for Latin America and signaled the emergence of a poor, missionary and paschal Church. [ABSTRACT FROM AUTHOR]

In this paper it has been presented the results about the study with high pressure steam schemes for the energy integration of a sugar mill with a pulp paper factory. The hypothesis for the integration is that it is possible to produce heat and electricity for both factories with the biomass of the sugar cane. This study includes the diversification of the production whit an ethanol factory for the pulp. The by bibliography, energy, material and cost balances are the main subjects for the best alternative of integration with high pressure schemes. The scheme with 61 ata and 440 °C was the best technically but not in the economic sense. [ABSTRACT FROM AUTHOR]

INTRODUCTION. This paper reports on the digital practices of 18 high school students' when taking notes with the text processor Word about the characteristics of on-line dictionaries--Spanish and English monolingual dictionaries and English-Spanish and Spanish-English bilingual dictionaries. The students explored the dictionaries and, in order to get familiar with them, they worked with the English verb get. The approach implemented refers to literacy in digital textuality. METHOD. The study contemplates the identification of multimedia resources and textual modalities in the dictionaries and the description of digital writing in the notes. Classification and textual analysis involves the informativity criteria identified in the dictionaries: language use, digital searches, textual designs, intertextuality sources, coherence and interactivity, as well as digital cohesion in descriptive and expositive writing, intertextuality by means of images, hyper links and lexical and graphic references. RESULTS. The notes show a predominant use of practical tools in the dictionaries in comparison to coherence and interactivity. They also evidence difficulties to integrate expositive and descriptive writing with digital modalities of intertextuality, hypertextuality and referentiality. DISCUSSION. Consideration and identification of various aspects of textuality in dictionaries show various degrees of intentionality and performance through digital and multimodal resources. However, teaching and practice support is necessary to fully appreciate the information, as well as the digital writing in notes. [ABSTRACT FROM AUTHOR]

Objectives. To characterize, by means of bibliometric indicators, the scientific publications of the Peruvian Experimental Medicine and Public Health Journal, 2010-2017. Materials and Methods. A bibliometric study in which the publications were retrieved from the data base of Scopus. The bibliometric production indicators were: number of publications per year and type of publication. Brief original and original articles were considered as units of analysis based on number of authors, institutional affiliation, and country of corresponding author, type of research and study design. The impact indicators were: number of citations by publication according to Scopus, metric of impact, such as CiteScore, Scimago Journal & Country Rank (SJR), and SciELO Public Health. Results. A total of 1,045 publications were made by the RPMESP: 40.1% of publications corresponded to original articles and original briefs; 1,837 authors contributed with these publications; 134 institutional affiliations were declared by the corresponding authors; 48,0% were research works on determinants of a health problem; on the other hand, 90.5% corresponded to observational studies. The publications analyzed received 945 citations, of which 78.5% were for publications for the 2010-2013 period. Conclusions. Four of ten publications of the RPMESP correspond to brief original or original articles. According to diverse formulas of calculation, the impact metric of the RPMESP shows an ascending trend; however, their magnitude is lower versus other regional journals. [ABSTRACT FROM AUTHOR]

From an historical analysis as well as considering the scientific, economical, social and political facts and consequences of scientific publications, a critical and updated review of scientific journals is made using a research perspective. It realizes the changes in the communication of Science, especially through twenty centuries. The historical analysis reveals that valuation of scientific knowledge, did not originate for commercial reasons, but responds to the political and economic evolution of society. The current situation of scientific publications reveals its enormous contribution to both knowledge and human development, but also inequities, social, economic and ethical conflicts.

Background: The use of isotretinoin is indicated in the treatment of severe acne; however, its adverse effects are important. Objective: To update the first Mexican Consensus on the use of isotretinoin in severe acne vulgaris, which took place in 2009. Methods: It was carried out a literature search between June 2009, and February 2015, in order to evaluate topics to be discussed; materials were sent to the experts to promote the debate among participants. The topics of interest were analyzed during the consensus with the Delphi modified method, using an instrument previously validated. 15 certified dermatologists with experience in handling acne with isotretinoin took part in the study; seven of them were involved in the previous consensus. Results: Several cases of isolated adverse events were identified. Neither systematic reviews, meta-analyses nor comparative, randomized, controlled clinical trials were published during the observation period. Conclusions: Isotretinoin is still the best treatment for severe nodulocystic acne. However, it must be taken into consideration its teratogenic effect on pregnant women and its association with inflammatory bowel disease, depression and suicidal ideas. Monitoring with laboratory tests is a tool for identifying possible adverse events. [ABSTRACT FROM AUTHOR]

In 2014 the Mexican government implemented taxes to reduce the consumption of sugar-sweetened beverages and nonessential energy-dense foods. In this manuscript, we analyze the scientific evidence linking the consumption of these products to chronic diseases, and summarize the studies that have evaluated the observed and expected impact of food taxes in Mexico. The implementation of taxes to unhealthy foods has reduced purchases of sugar-sweetened beverages in 7.6% and nonessential energy-dense foods in 7.4%. A reduction in consumption could decrease obesity prevalence by 2.5%; prevent 20 000 cardiovascular disease events; 189 000 diabetes cases; and 20 000 cardiovascular deaths. Additionally, this impact could save nearly 1 173 million dollars from healthcare costs. Taxes to unhealthy foods should be strengthen up and remain as an integral part of the national strategy to reduce obesity and chronic diseases in Mexico. [ABSTRACT FROM AUTHOR]

This note describes an experience of archival work with born-digital records. The remarkable presence of digital tools and techniques on the historian's desktop and the growing series of binary documents originates questions and problems in the daily intellectual work. The tensions between archival practices with dispositions pertaining to the print culture and the kind of experience described in this note call for new and enriching approaches. Two approaches are presented here that renew questions about the notion of Archive. [ABSTRACT FROM AUTHOR]

A model of a paper napkins winder based on Newton's second law is described. A method for controlling angular velocity with a splitter controller developed in a PLC to enhance the action of the controller present on a Siemens SINAMICS drive line is proposed. The tension is measured by a sensor and converted to current signal to be sent to the PLC Splitter in order to soften it before entering Sinamics PID controller to keep the process within the desired range of control. A simulation of the industrial application is performed by Matlab's Simulink® and validates the real controller design. Finally, obtained and verified control is implemented on a paper napkins processing machine, where the results show the effectiveness of the proposed controller. [ABSTRACT FROM AUTHOR]
