El surgimiento de las sociedades aldeanas tempranas trajo aparejado, además del establecimiento en viviendas permanentes, el desarrollo de nuevas estrategias productivas y la incorporación de productos domesticados a las prácticas alimenticias. Los ingredientes vegetales que fueron paulatinamente integrados a la dieta y recetas de quienes habitaban estas aldeas requirieron conocimientos acerca de cómo obtenerlos y cultivarlos y la implementación de diversas técnicas de procesamiento que permitieran adquirir subproductos a partir de los cuales crear alimentos. En este trabajo, a través de un abordaje que incluye el estudio de macro y microrrestos vegetales y de las materialidades implicadas en la elaboración de alimentos, nos centraremos en dirimir cuáles fueron las técnicas implementadas para procesar productos vegetales en Puesto Viejo, un sitio aldeano ocupado durante el primer milenio D.C. (Quebrada de Los Corrales, Tucumán, Argentina). Las evidencias analizadas permiten afirmar que las sociedades que habitaron este sitio manejaron, para su consumo, una gran diversidad de vegetales domesticados y silvestres, aplicando distintas técnicas y modos de elaboración centrados en el hervido y tostado.

Identificamos que las metodologías permiten una construcción de la solución de manera eficiente mediante fases apoyadas en herramientas, modelos y frameworks para su construcción; siendo la metodología empírica la más utilizada para la construcción de estas soluciones de inteligencia de negocios.

El trabajo tiene como objetivo determinar las maderas preferidas a partir del análisis de diferentes atributos para la elaboración de muebles en la provincia de Cabinda, Angola. Se evalúa una población perteneciente a los municipios Cabinda, Cacongo, Buco Zau y Belice. El método utilizado para medir las preferencias de los especialistas fue el Proceso de Análisis Jerárquico, a partir de una encuesta al personal especializado en el procesamiento y utilización de la madera y profesores de la Carrera de Ingeniería Forestal en la Universidad 11 de noviembre en Cabinda. Para la determinación de la calidad del cepillado de maderas de gran abundancia en Cabinda se empleó la Norma ASTM-D-1666-2004. Las maderas de mayores preferencias en el mercado del mueble son Guarea cedrata, Lovoa trichiliodes, Grossweilerodendrum balsimifera, Ballonella toxisperma y Clorophora excelsa. El resultado del análisis jerárquico del proceso expone que la especie de mayor aceptación de manera es Grossweilerodendrum balsimifera, al presentar un rango de aceptación del 56 %. Se aprecia una preferencia de maderas con colores claros, lo cual se sustenta por el hecho que, entre las cinco maderas preferidas, tres presentan coloración con matices claros, representando el 70,33 % del total de la muestra analizada. Durante el análisis de la calidad del cepillado se aprecian resultados positivos para las especies Entandrophragma angolensis, Entandrophragma cilindricum y Terminalia superba; al presentar un promedio de 24,4 marcas de cuchilla por centímetro.

The objective of the study is to determine the preferred woods based on the analysis of different attributes for the production of furniture in the province of Cabinda, Angola. A population belonging to the municipalities of Cabinda, Cacongo, Buco Zau and Belize is used. The method used to measure the preferences of the specialists was the Hierarchical Analysis Process, based on a survey of personnel specialized in the processing and use of wood and professors of the Forestry Engineering Course at the University "11 de Noviembre" in Cabinda. To determine the quality of planning of highly abundant woods in Cabinda, the ASTM-D-1666-2004 Standard was used. The favorite woods in the furniture market are Guarea cedrata, Lovoa trichiliodes, Grossweilerodendrum balsimifera, Ballonella toxisperma and Clorophora excelsa. The result of the hierarchical analysis of the process shows that the most widely accepted species is Grossweilerodendrum balsimifera, presenting an acceptance range of 56%. There is a preference for woods with light colors, which is supported by the fact that, among the five preferred woods, three have light shades, representing 70.33% of the total sample analyzed. During the analysis of brushing quality, positive results are seen for the species Entandrophragma angolensis, Entandrophragma cilindricum and Terminalia superba; since they have an average of 24.4 blade marks per centimeter.

The obtaining of BiFeO3 in the form of a thin film represents a critical issue for its application in electronic devices since this is the required geometry for the integration of this material in microelectronic circuits. There are several techniques for this purpose, from those that use a gas or plasma phase to transport the precursors to the substrate, which would be included within the PVD or CVD techniques (for its acronym Physical Vapor Deposition and Chemical Vapor Deposition) to those that use a phase liquid for this transport, which would be included under the CSD (Chemical Vapor Deposition) techniques. However, among the large number of published papers, there is much controversy about which of them would be most suitable. It has been clearly demonstrated that all of them have the sufficient capacity to produce uniform and homogeneous thin films in thickness throughout the entire substrate, and although in many articles pure BiFeO3 films have been obtained with an exploitable functional response, others have reported the typical drawbacks that usually entails the obtaining this material: appearance of secondary phases, high leakages or a poor functional response. Nevertheless, there is a common aspect in the specialized literature that seems to be in agreement: the first group of techniques require very sophisticated equipment that involves high energy consumption in terms of temperature and pressure (vaccum), while the techniques that are based on solutions are characterized by their higher simplicity. In this context, the purpose of the present review is to summarize the main aspects of each technique in the obtaining of BiFeO3 thin films, from those that are more sophisticated to the simplest and environmentally benevolent ones, in order to provide an easier understanding of them. Resumen: La obtención de BiFeO3 en forma de lámina delgada representa una cuestión crítica para su aplicación en dispositivos electrónicos ya que es la geometría requerida para la integración de este material en circuitos microelectrónicos. Existen varias técnicas para este fin, desde las que utilizan una fase gaseosa o plasmática para transportar los precursores al sustrato, que se englobarían dentro de las técnicas PVD o CVD (por sus siglas en inglés de Physical Vapor Deposition y Chemical Vapor Deposition) hasta las que utilizan una fase líquida para este transporte, que se englobarían dentro de las técnicas CSD (Chemical Vapor Deposition). Sin embargo, entre el gran número de trabajos publicados, hay mucha controversia sobre cuál de ellas sería la más adecuada. Se ha demostrado claramente que todas ellas tienen la capacidad suficiente para producir películas delgadas uniformes y homogéneas en espesor a lo largo de todo el sustrato, y aunque en muchos artículos se han obtenido películas puras de BiFeO3 con una respuesta funcional aprovechable, otros han reportado los típicos inconvenientes que suele conllevar la obtención de este material: aparición de fases secundarias, corrientes de fuga altas o una pobre respuesta funcional. Sin embargo, hay un aspecto común en la literatura especializada que parece coincidir: el primer grupo de técnicas requiere de equipos muy sofisticados que implican un consumo energético alto en términos de temperatura y presión (vacío), mientras que las técnicas que se basan en disoluciones se caracterizan por su mayor simplicidad. En este contexto, el propósito de la presente revisión es resumir los principales aspectos de cada técnica en la obtención de películas delgadas de BiFeO3, desde las más sofisticadas hasta las más sencillas y respetuosas con el medio ambiente, con el fin de facilitar su comprensión.

El presente estudio se basa en el análisis de una empacadora de camarón, con el objeto de evaluar el paradigma de la economía circular. Para esto, se realizó un enfoque de información con el objetivo de plantear mejoras para el reciclaje y reutilización de los residuos con la aplicación de métodos basados en la economía circular dentro de la empresa. El tipo de investigación que se utilizó es la descriptiva y de campo porque se caracterizó parte de la producción de camarón y las variables de economía circular. Se dispuso de una lista de chequeo para su evaluación. En los resultados obtenidos, se determinó que la producción de la empacadora de camarón está trabajando en una economía lineal, y que la empresa tiene una economía circular en un nivel medio de aplicación. Esto permitiría mejoras en la sostenibilidad incrementando más la economía circular.

The objective of this study was to determine the main preferred woods for the furniture manufacture in the provinces of Pinar del Rio and Artemisa. The method used to measure the preferences of the specialists was the so-called Hierarchical Analysis Process through the application of a survey to 350 individuals related to the consumption of wooden articles. The results obtained allowed us to define that the most preferred woods for the production of furniture are Swietenia mahagoni (L.) Jacq., Cedrela odorata L., Cordia gerascanthus (L.) Moldenke, Hibiscus elatus L. y Tectona grandis Sw. From the application of the hierarchical analysis of the species selection process, it is stated that the most accepted species is Swietenia mahagoni, presenting an acceptance range of 100 %. Respondents also state that the attributes associated with quality aspects have a great impact on the preference of the product over the designs, when the furniture is made of solid wood. Based on the forest management project of the Costa Sur (Artemisa), Pinar del Río and Macurije (Pinar del Rio) agroforestry companies, it was defined that Pinus caribaea var caribaea, Eucalyptus saligna, Samanea saman, Gmelina arborea y Acacia mangium have the potential to be used in the furniture industry based on their volumes and permanence in the forest heritage of the companies studied.

The article reflects on the cooperative thinking of Alexander Chayanov and its application in two case studies in Argentina: the Agricultural Union of Avellaneda in Santa Fe and La Riojana in La Rioja. The importance of studying the material conditions of the members and the objectives of the cooperatives is highlighted, as well as the need to link organizational structures with the sociocultural context and economic needs of the peasantry. The contributions of Chayanov to agricultural cooperativism are analyzed, and the transformations and challenges of Argentine cooperatives are described. The Agricultural Union of Avellaneda has diversified its activities and has taken on the marketing and industrialization of various sectors, except partially in the poultry sector. La Riojana, on the other hand, is a wine cooperative that has obtained the Geographical Indication "Valles del Famatina" and has become the largest producer of organic wines in Argentina.

This work presents a proposal for a Recovery Plan for Degraded Areas for the headwaters of the Mandaguari stream, located in the city of Catalão-GO. The recovery plan is of paramount importance to protect native vegetation and ensure compliance with the requirements brought by Law 12.651/2012. The objective of this work is to use satellite images, orthophoto created using the DJI Mavic 2 PRO drone, for the elaboration of diagnosis, prognosis, intervention proposal and management of the study area. Using drone and image processing applications (dronedeploy), an orthophotomosaic of the study area was carried out, which through geoprocessing software (qgis) maps of location, delimitation of springs and watercourses and land use were prepared. The use of the land in the area points to the existence of areas of native vegetation in its interior, together with the predominance of regions of pasture, forestry, roads, silted area, area of planting of native species. From the diagnosis, it was noted that the area has, within the permanent preservation areas - APP, pastures, roads, eucalyptus, in addition to a part of the stream being silted up, without showing signs of natural regeneration. The prognosis of the study area points to the need for intervention to ensure the recovery of the area and prevent the emergence of erosion processes. This intervention is detailed in the proposal, where an intervention technique was determined for each area, in addition to establishing the monitoring and maintenance strategies necessary for the proper implementation of the plan.

ProGas v1.1 was developed to support researchers in the preprocessing and data analysis of in vitro gas production of ruminant foods. For the implementation of this program, Microsoft Office Excel 2007 was used. The conversion of data to volume (mL g-1 incOM) was carried out with an established equation. The duration of the gas production phases was estimated by means of the average variation rates and the critical points. A total of six sheets were designed in the program: general, enter pressures, accumulated volume, critical points, graphs and help. It is concluded that the proposed program allowed preparing the experimental data for its subsequent modeling. In addition, the methodology that was applied to estimate the critical points did not require a mathematical model to calculate the duration of the in vitro gas production phases, which facilitated the description of the degradation kinetics of the evaluated foods.

En el proceso penal es fundamental que los tribunales posean todos los medios de pruebas posibles para poder enervar el Derecho Fundamental a la Presunción de Inocencia. Es frecuente que, ante la escasez de pruebas directas, los juzgadores tengan que hacer uso de la prueba basada en indicios para fundamentar la culpabilidad del investigado. En este sentido, la concurrencia de huellas dactilares, pruebas de ADN, testigos o hechos observados durante la inspección ocular son necesarios para que los juzgadores alcancen la certeza jurídica sobre la culpabilidad del sujeto. Sin embargo, actualmente, no se está prestando atención a las características del olor humano, que permanece en la escena del crimen y permite que los canes puedan identificarlo rápidamente. En esta línea, la odorología forense, a través del informe pericial odorológico, puede constituirse como un elemento más de prueba que, junto a la pluralidad de indicios que requiere la jurisprudencia española, permitan reforzar el carácter unidireccional e indirecto de la prueba indiciara.

Este trabajo tiene como objetivo estudiar las diferencias de procesamiento que se producen al aplicar una lógica de tipo deductivo frente a una lógica por defecto. Como los entrañamientos se fundamentan en la lógica deductiva, mientras que las implicaturas conversacionales generalizadas (ICG) se construyen a partir de la lógica por defecto, se propusieron dos cuestionarios destinados a registrar la eficacia de procesamiento entendida como el número de aciertos por minuto. Los datos recogidos muestran que existe una diferencia significativa en el procesamiento de los entrañamientos y de las ICG: los entrañamientos se procesan de forma más eficaz que las ICG y, por tanto, se concluye que la lógica por defecto exige un mayor esfuerzo cognitivo.

This paper proposes a double reflection on the cognitive differences between humans and machines from ethics. In the first place, I will try to differentiate between human thought and machine processing through etymological, semantic and comparative methods that will reveal why it is not possible to attribute thinking capacities to artificial intelligences. On the other hand, these terms will be related to the praxis of representative democracy through various examples. This analysis is based on three aims: the need for mutual recognition through language; the commitment acquired through the word; and democracy as an expression of justice. [ABSTRACT FROM AUTHOR]

Para la detección de las altas capacidades (AC) se ha enfatizado las pruebas de inteligencia y no otros criterios. Obtener una baja puntuación en la velocidad de procesamiento (VP) posiblemente afecta en la identificación de AC. Esto repercute en que a estos sujetos se les limite la posibilidad de potenciar sus capacidades en programas educativos específicos. Para comprobar en qué medida la VP es baja en niños susceptibles de AC se evaluó a 32 participantes, de entre 8 a 16 años, con las siguientes pruebas: escala de inteligencia Weschler (WISC-5), pruebas de creatividad TCI (Evaluación del pensamiento creativo en educación primaria), PIC-N o PIC-J (Prueba de imaginación creativa en niños), aplicadas dependiendo de la edad del niño, y CPT3 (Conners Continous performance test 3rd edition). Se encontró efectivamente que la VP esta disminuida en relación con los otros índices de los resultados en el WISC-5. Sin embargo, en el estilo de respuesta del CPT3, se encontró una tendencia clara al equilibrio ante una tarea cognitiva, lo que significa que la precisión y la velocidad se corresponden. Por lo tanto, siguiendo los criterios convencionales y según los resultados encontrados en el coeficiente intelectual total (CIT) de la prueba de inteligencia, tan solo el 6,2% del total de los participantes serían identificados con AC. Así mismo se beneficiarían del acceso a programas educativos especializados y adaptaciones curriculares. Se concluye que para la detección de AC se debería tomar en cuenta otros aspectos aparte del rendimiento intelectual, como la creatividad, personalidad, entorno de desarrollo, motivación e intereses, ya que la velocidad no dicta la capacidad del sujeto para culminar satisfactoriamente una tarea cognitiva, puede que para ciertos sujetos implique mayor cantidad de recursos cognitivos en la resolución de problemas.

La visión artificial es una disciplina de la inteligencia artificial que aplica el procesamiento de imágenes para el reconocimiento de patrones, con el uso algoritmos en ambientes controlados con una cantidad de iteraciones en el procesamiento de imágenes.

Esta fue una investigación aplicada, de tipo cuasi experimental, con corte transversal, la población y muestra de estudio fueron 8 patrones de imágenes, la técnica fue la verificación con lista de chequeo, aplicada a 2 grupos, un grupo control y un grupo experimental. Se concluyó que el tiempo de procesamiento para el reconocimiento de 8 patrones de imágenes del grupo experimental fue de 10,75 segundos y de 67,75 segundos para el grupo control y con un grado de relación entre el reconocimiento de patrones y el sistema de visión artificial de 72 %.

Currently, the food industry seeks to offer fresh food products but also have a long shelf life. There are several techniques that need heat treatment which allow prolonging the shelf life of food but these can affect the final quality of the product. High hydrostatic pressure and homogenization by high pressure are new non-thermal techniques that allow to act on food at low process temperatures, lengthening the shelf life and preserving the nutritional quality. High hydrostatic pressure has been applied to different minimally processed fruits to preserve their freshness and nutritional properties, including peaches, mango, cherries, strawberries, orange pulp, melon, custard apple and olives where it has been determined that this technique better preserves the properties of these plant materials compared to conventional heat treatments. Regarding high pressure homogenization, it has been applied in apple, strawberry, mango, watermelon, grapefruit and orange juice juices, obtaining a good inactivation of microorganisms and a better preservation of bioactive compounds that improve nutritional and functional properties.

Blancmange is a dairy product commonly consumed in Latin America. In Colombia, a large part of its production is artisanal and is carried out by small and medium-sized enterprises (SMEs). The quality standards of manjar blanco processing in these SMEs can be improved through Hazard Analysis and Critical Control Points (or HACCP). In this study, a HACCP plan for the manufacturing process of manjar blanco in a dairy products company in Popayán (Cauca). Initially, the sanitary profile of the company was assayed, detecting 70 % compliance. Then, a descriptive study was carried out by application of the seven principles of HACCP; hazards were identified for raw materials and supplies and for the process. The proposed plan contains: description of the product and its use, flowchart of the process, hazard analysis, table of plan control with the critical control points (CCP), preventive actions and the establishment of documentation and verification procedures. Processing stages identified as PCC were fresh milk reception, final concentration, dosage, cooling, sealing & labeling, and storage. The incidence of chemical and biological hazards identified on the safety of the product must be verified experimentally. [ABSTRACT FROM AUTHOR]

Laguna Las Vegas is a high integrity and high resolution site. It is a penecontemporaneous record that was formed around 3050-3210 BP which is remarkable due to the high frequency of guanaco bones (Lama guanicoe) and, to a lesser extent, of cauquén remains (Chloephaga sp.). Additionally, a high frequency of bone pounders and chalcedony scrapers was recorded. We propose that this site was a campsite originated by an attritionally discard behavior within a short time frame, in which whole preys (guanacos) were taken for processing, consumption, and subsequent transport of their axial skeleton. The fact that cauquén remains were found suggests that human occupations took place, at least, during spring and summer. Due to these features, Laguna Las Vegas stands out as a valuable site, one which adds useful information about faunal resource management and mobility of the hunter-gatherer populations of the Coyle River middle basin.

The increase in companies and the incessant productive growth of the different economic sectors have increased programs that contribute to the sustainable consumption of electrical energy, all to foster a culture of savings. The use of standardized and calibrated tools is essential, with a constant monitoring of the various electrical parameters of the industry can be done. The prototype has a STM32F7 as a microcontroller system for digital signal processing in real time, as well as the choice of voltage and current sensors for its correct functionality. The prototype can rival with commercials meters since its range error in tests is minimal, being thus an average error that does not exceed 10 %. With the results obtained, we conclude that the prototype is applicable, this being a viable and economical option for an energy audit, limited only by the number of prototypes that can be created for a possible solution for its application.

On the other hand, for the Eucaliptussaligna and Samaneasaman the most adequate resulted the combination 1 (speed rate 7,32 m*min-1, number of knife 3, cutting angle 200 and cutter-head speed 6200 rpm).

En la actualidad existen varias técnicas para evaluar la conducta ansiolítica en animales de laboratorio, debido a que su comportamiento es muy similar al del ser humano, dichas técnicas incluyen métodos manuales y visuales, donde el evaluador debe observar atentamente todo el experimento y documentar cada uno de los eventos de interés realizados por el ratón, o a su vez adquirir equipos electrónicos que cumplan esta función, sin embargo, esta alternativa podría ser demasiado costosa. El presente artículo plantea el diseño e implementación de dos equipos evaluadores de ansiedad de bajo costo (Laberinto en Cruz Elevada y Cuarto Claro Obscuro) mediante procesamiento digital de imágenes, los mismos que después de la validación del funcionamiento entrega resultados de manera automática a través de una aplicación desarrollada en Matlab. Los resultados brindados por la aplicación coinciden con aquellos que un observador obtendría de forma manual y visual, lo que facilita las labores del evaluador y reduce notablemente los posibles errores humanos y de ambigüedad existentes en las pruebas manuales.

Con el objetivo de seleccionar los materiales de papa con mejor adaptación a las diferentes localidades consideradas se evaluaron clones promisorios (382151.22, 382121.25, 386528.7), variedades comerciales (Dorinia, Marilinia, Muskainia, Cristalinia) y las variedades de uso local (Montañita y Sin Nombre Táchira), como testigo se usó la variedad Granola, en cinco localidades del estado Mérida, Venezuela.

This paper analyzes plant processing through lithic instruments from a multi-proxy approach for hunter-gatherers contexts of Patagonia. This region presents an archaeobotanical record reflecting the use of diverse species and plant organs, as well as abundant lithic record with evidences of plant processing in different occupational periods. An experimental program combining plant micro-residues studies of two taxa common in the archaeological record with the use-wear analysis of lithic material is proposed here in order to generate functional, technological and methodological interpretations. Cell elements, stains and traces of use are characterized. The program was applied to a sample of different archaeological instruments of the Central plain and the North coast of Santa Cruz province. Micro-residues and use-wear traces identified from these artifacts, together with other contextual information allow us to infer diverse plant processing and manufacture practices.

The present investigation was developed with the objective of valuing the energy potential of the available agroindustrial residuals of tomato in the Factory "19 de Abril" of Mayabeque province, for the biofuel production. It was carried out the characterization of the residual mixtures of tomato through physical-chemical and energy indicators to estimate the energy potential that would be contributed starting from their use in the bio-ethanol obtaining; in turn the necessary conditions were valued for the recycled of these residuals. Starting from the gathered information and the identification of the agroindustrial residuals generated in the factory, it was evidenced that the tomato residuals are those that bigger frequency and quantity present. The physical-chemical characterization of these residuals evidenced the necessity to use indirect roads of prosecution, as well as the formation of mixtures with other residuals obtained in this factory that it optimizes the prosecution conditions. As main result it was considered the energy potential of the mixture of the available agroindustrial residuals of tomato, being evidenced the possibility of bioethanol production, starting from the adaptation of the methods of prosecutions, conditions and alternative to the characteristics of the residual mixture and those of the means where it is developed in a viable and sustainable prosecution. It is recommended for future studies to identify the most efficient process and to improve the way and the conditions of storage of the residuals in the factory for their possible recycled.
