La Fotografía de Lucha Libre Mexicana
Authors: Reyes Vázquez Juan Carlos , German Blanco Jimena
Published: February 2020

La imagen fotográfica se ha encontrado constantemente ante diversas encrucijadas: epistémicas, tecnológicas, estéticas y representacionales. En el caso de la fotografía de lucha libre, la imagen de esta personificación forma ya parte de un imaginario colectivo identitario. Por ello nuestro objetivo es realizar una propuesta sobre por qué la fotografía de lucha libre puede ser considerada una “imagen fuera de lugar”, una imagen de características liminales. De igual manera, pretendemos analizar por qué el fotógrafo de lucha libre en México podría ser considerado también un sujeto liminal. En concreto, se argumenta que dichas imágenes pueden ser consideradas liminales porque muestran espacios de “carnaval” en los que la lógica cultural habitual se paraliza y temporalmente aplican otras reglas. Para ello, plantearemos a través de los conceptos de catarsis, simulacro y espectáculo el por qué la fotografía de lucha libre puede ser considerada como una imagen “al margen”.
Arte transformador
Authors: Aguilar Hernández Yuri Alberto
Published: February 2020

Pensar el arte ampliando su campo de acción más allá del ambito profesional, nos permite internarnos en el espacio social y reflexionar en la utilidad social del arte. Un arte que indaga sobre la multidimensionalidad vinculante entre arte y sociedada,  comenzando con la noción de la escultura social, y continuando algunas prácticas instituyentes actuales. Talleres comunitarios, arquitecturas colectivas y tácticas urbanas son las herramientas artisticas utilizadas para la transformación social de algunas comunidades de Tlalpan y Xochimilco en la Ciudad de México. Donde la colaboración y producción cultural se entremezclan para potenciar y describir las posibilidades de agencia que tiene el arte actual. Metodológicamente se plantea las prácticas artisticas como formas de experimentación y la obsevación participante como herrameinteas de reflexión y análisis.

Published: February 2020

Preparation of different stem forages is a guarantee of balanced feeding of cattle with steady maintenance. The promising technology of harvesting stalk feed, which allows you to save in the selected mass of the most valuable fractions - leaves, buds and inflorescences, is the use in the technological process of press-pickers or pickup trucks-conveyors, which contain a beatter – blade grinding unit with active disk blades. The milling of the leaf mass is one of the most energy-intensive operations in the overall process of harvesting, which also depends on the final quality of the resulting feed. The shredder is the main working unit of the feed assembly, which defines its technological scheme and the location of the main units. The main structural features of different types of crushers are considered, namely: drum, disk, rotary and multi-plane cutting, with their disadvantages and advantages in the process of work. The purpose of the article is to evaluate the various forage harvesting units in the production of haymaking on competitiveness by comparing their technical and operational indicators. The design and principle of the proposed beatter - blade grinding unit is described. The main factors influencing the process of cutting the grass mass are established. The regression equation describing the change in the specific cutting operation is given, depending on the structural and technological parameters, in particular on the sectional area of the cut mass and its moisture content. It has been established that the size of the cross-sectional area of the material most influences the optimization criterion. At humidity of alfalfa 45-55% the specific work of cutting with increasing feed is constantly decreasing, respectively, from 23,6-19,6 kJ/m2 to 6,37-4,10 kJ/m2. The methodology for evaluating the competitiveness of technical means for the harvesting of cut alfalfa with simultaneous grinding on the dimensionless and generalized indicators of the 1st and 2nd species is described. It was found that the maximum value of the generalizing index of the first species is 0.6997, and for the II-th - 3.7960 and corresponds to the prototype PV-6, which is equipped with a multi-flat cutter.
ТНЕ FERMENTED SOUR-MILK DESSERTS WITH BIFIDOGENIC
Authors: Solomon Alla , Polyevoda Yurii
Published: February 2020

Probiotic cultures that provide a beneficial effect on the consumer's organism and normalize the composition and functions of the microflora of the gastrointestinal tract include such types of lacto-and bifidobacteria as Lactobacillusacidophilus, Lactobacilluscasei, Bifidobacteriumspp. (B. adolescentis, B. animalisssp. Lactis, B. bifidum, B. longum, B. breve). Bifidobacteria are one of the most important groups of intestinal microorganisms that dominate the anaerobic flora of the colon. The International Dairy Federation calls bioproducts such mixtures that contain at least 1 ∙ 106 bifidobacteria in 1 cm3. It should be noted that for most microorganisms that are representatives of the normal microflora of the human intestinal tract, milk is an unfavorable environment for their development. This is due to the fact that low-molecular compounds, such as free amino acids, monosaccharides, essential for the development of microorganisms are practically absent in milk, and the fact that most bacteria of the genus Lactobacillus, Lactococcus and Bifidobacterium belong to obligate anaerobes, which are negatively affected by air oxygen. Therefore, bifidobacteria that belong to anaerobes in milk develop very slowly.
Bifidobacteria are actively involved in the restoration of normal intestinal microflora in gastrointestinal diseases and after antibiotic treatment. To stimulate their development, it is necessary to use strains of bifidobacteria adapted to milk, to provide the necessary composition of the nutrient medium and growth stimulants for their development, and also to cultivate them together with lactic acid bacteria that have high β-galactosidase activity, which increases their own β-galactosidase activity bifidobacteria.

Authors: Bandura Valentyna , Popiak Oleksandr
Published: February 2020

The article reviews various techniques for mathematical modeling of the soybean drying process. The purpose of this paper is to review, analyze and compare existing approaches to mathematically describe the processes of moisture movement during microwave drying of soybeans. The only way to provide mathematical modeling of the processes occurring in the soybean grain is a combination of the transformation of microwave energy into heat, the heating of dipole water molecules existing in the seed, the processes of moving moisture from the center to the grain shell and evaporation of moisture. Today, microwave drying is one of the promising areas for research, because this method is much more efficient than traditional post-harvest grain drying methods and, at the same time, poorly understood. Factors on which the process of microwave drying depends on are the speed of movement of moisture in the micropores of the product, the initial temperature and humidity of the raw material, the placement of the main magnetron relative to the object of drying and the speed of movement of raw materials in the drying chamber. The object of the study in this article was to simplify the mathematical model of soybean seeds.
To intensify the process of microwave drying, it is advisable to use a combined effect, such as blowing, which increases the intensity and quality of the process of microwave dehumidification. In addition, in this case, the simultaneous use of two or more factors of influence, which allows for rapid processing of raw materials. This determines the relevance and prospects of this study. The developed criteria criterion is substantiated and described, which allows to simplify the complex calculation of microwave energy transfer processes, sample heating and moisture velocity in it.
The basic approaches to the construction of a mathematical model of the soybean drying process are considered, and their expediency is determined. The analysis of various methods of mathematical description of the drying process is carried out, the main disadvantages of these methods are identified. It is established that drying soybean seeds in the microwave field is one of the most promising. A mathematical model for a combined soybean drying process with a combination of microwave drying methods and air blowing is proposed.

The safety of milk and dairy products as a whole can be determined by a comprehensive indicator - animal health. Thus, in accordance with modern international requirements, the farm where raw milk is produced for the production of dairy products must: comply with the rules of hygiene and veterinary sanitation; meet the requirements of good manufacturing practice; carry out identification and registration of animals; ensure proper documentation on the receipt of feed, hygiene and sanitation of medicines; to monitor in the pre-fermer laboratory the quality and safety of milk; compulsory registration of feeds coming from animals because of the feed that can cause human health hazardous substances (hormones, antibiotics, etc.); record veterinary medicinal products used for the treatment of animals; to record the occurrence of those diseases in animals that threaten the safety of milk.
EU standards require strict compliance with food safety and quality requirements. The country, which cannot keep track of all stages of production, is closed to the European market.
The analysis of quality indicators of milk received for processing is made. It has been established that milk from households has low quality indicators. Higher- and first-grade milk comes from agricultural enterprises.
Milk quality means its high hygienic performance, the content of a certain amount of protein, fat, vitamins, enzymes, hormones, mineral salts and other substances. It should not contain any neutralizing substances (antibiotics, soda, hydrogen peroxide). The content of heavy metals, pesticide residues should not exceed the maximum permissible level.
Therefore, the safety of raw materials is a guarantee of the safety of finished products in the domestic market and its competitiveness in foreign markets.

Published: February 2020

Problems within agriculture, food, and natural resource (AFNR) systems are increasingly complex, expanding the need for students to develop problem-solving abilities alongside an understanding of their own thinking. In this effort, we explored the problem-solving abilities, metacognition, and systems thinking of current AFNR secondary school students. A descriptive correlational study design was employed. Data were collected via an online, Qualtrics survey. Student responses on the metacognition, systems thinking, and problem-solving ability survey items suggested opportunities for increased focus on these areas throughout their educational experience. In addition, statistically significant relationships between metacognition and systems thinking and systems thinking and problem-solving ability reinforced the importance of these topics within AFNR Education. Recommendations emerging from this work include additional emphasis on metacognition, systems thinking, and problem-solving skills within secondary school AFNR classrooms; utilization of specific strategies to increase systems thinking; operationalizing specific strategies to increase metacognitive knowledge and metacognitive regulation; along with a cross-cutting recommendation for teachers to make their thinking more explicit during instruction to increase metacognition, systems thinking, and problem-solving skills among learners.
Reinterpretando un sitio arqueológico en Pampa Seca

Published: February 2020

En el año 2006 comenzaron a realizarse en el Departamento General Roca (pcia. de Córdoba), estudios arqueológicos sistemáticos. El abordaje inicial del área, carente de investigaciones previas, fue realizado con premisas propias de la Ecología del Comportamiento Humano o Ecología Evolutiva (amplitud de la dieta, selección de parcelas y teorema de valor marginal, etc.). De esta forma se intentó conseguir un panorama de base amplio sobre las relaciones entre los grupos cazadores-recolectores y su ambiente. La nueva información recolectada posibilitó la utilización de diferentes perspectivas o vías de entrada al registro para complementar los modelos que se están utilizando. Algunas de las hipótesis puestas en discusión desde La Etnoarqueologia resultaron de especial utilidad para el abordaje sobre los sitios, su materialidad y su contexto ideológico.

Published: February 2020

El objetivo del presente trabajo es dar a conocer la secuencia temporal prehispánica de la Quebrada de Los Corrales, ubicada en el abra de El Infiernillo (Tucumán) e insertarla en el marco témporoespacial regional. Tradicionalmente las investigaciones en el NOA se han concentrado en ciertas áreas dejando de lado a otras áreas consideradas marginales como El Infiernillo. Sin embargo, nuestras investigaciones dan cuenta de la presencia de sociedades humanas desde momentos tempranos (anteriores a ca. 2500 años AP) y hasta momentos tardíos (ca. 600 años AP). La información generada durante cinco años de trabajo nos lleva a plantear que El Infiernillo y más precisamente la Quebrada de Los Corrales estuvo lejos de tener un carácter marginal en tiempos prehispánicos.

En este trabajo buscamos defi nir distintas lógicas espaciales en la construcción social de los entornos rupestres de las Sierras de El Alto-Ancasti. Para ello realizamos un análisis comparativo de diez sitios arqueológicos. Nuestra metodología considera la idea que una de las dimensiones fundamentales del arte rupestre es la visualidad y que ello defi ne la estructuración del espacio en torno a él. Defi nimos cuatro modalidades espaciales considerando las posibilidades de visualización, agregación de personas y movimientos corporales que los entornos rupestres promueven o limitan, entre otros elementos de análisis. Interpretamos dos de estas modalidades como estructuras espaciales de formas rituales particulares y exploramos los límites y alcances de la defi nición de estas lógicas espaciales en términos de la tensión entre lo general y lo particular en el arte rupestre a distintas escalas de análisis.

Para ello se plantea que el intercambio solo es posible como consecuencia de una estructura que pueda garantizar su efectividad y continuidad en el plano social y que esto es llevado a cabo por acciones colectivas en situaciones estructuradas. Se revisarán casos de análisis para discutir la naturaleza del tráfi co de bienes que comprenden la distribución de las obsidianas, las cerámicas San Francisco y La Isla. Estos casos serán útiles para discutir los mecanismos, agentes y organización política del intercambio. Por último, a partir de estas cuestiones teóricas y fácticas trataremos de ofrecer una serie de explicaciones plausibles acerca de las características del sistema de intercambio.
Lo pasado…arado: impacto del desarrollo agrícola moderno sobre el patrimonio arqueológico prehispánico del área pedemontana meridional de la provincia de Tucumán (Argentina)
Authors: Miguez Gabriel
Published: February 2020

esumen En este trabajo se indaga acerca del grado de impacto que el intempestivo avance de la frontera agrícola ha tenido sobre el patrimonio arqueológico de las tierras bajas de la provincia de Tucumán, con el énfasis puesto en la porción meridional del área pedemontana. Se aborda el tema integrando los datos obtenidos en recientes prospecciones arqueológicas con el análisis bibliográfi co de tópicos vinculados con el desarrollo de la agricultura moderna. A partir de ello se describen los principales mecanismos de alteración producidos por las actividades agrícolas sobre los restos arqueológicos y la incidencia de ciertos factores ambientales en dicho proceso destructivo. Se analiza también la magnitud de este impacto en perspectiva histórica y se refl exiona acerca de la difícil situación existente entre el progreso agrícola y la preservación de los sitios arqueológicos en la actualidad. Se concluye que las actividades agrícolas son la principal causa de alteración del patrimonio arqueológico en las tierras bajas tucumanas, afectándolo de múltiples maneras. La magnitud de este impacto ha ido en aumento desde hace más de un siglo, hecho que plantea la implementación de medidas urgentes para mitigar esta situación, algunas de las cuales se proponen aquí.
Guanacos, sexo y edad. El caso del sitio Las Vueltas 1 (Tierra del Fuego, Argentina)
Authors: Colasurdo María Belén , Santiago Fernando , Salemme Mónica
Published: February 2020

El sitio Las Vueltas 1 (Tierra del Fuego, Argentina) ha sido defi nido como sitio de matanza y procesamiento de guanacos; los diversos eventos de captura han dejado como registro un NISP total de 3404 huesos de guanaco (de los cuales 1751 provienen de la 3ra ocupación), donde todas las partes esqueletarias están representadas diferencialmente. El objetivo de este trabajo es dar a conocer el sexo y la edad de los guanacos cazados durante la ocupación más reciente de este sitio considerando que el análisis de la estructura sexual y etaria de los conjuntos zooarqueológicos aporta valiosa información para identifi car estrategias de caza, así como si las mismas se concentraron sobre algún grupo social, etario o sexual en particular. Para determinar el sexo y la edad de los guanacos de LV1 se tuvieron en cuenta análisis odontométrico y medidas osteométricas en pelvis, utilizando todos los fragmentos de maxilares, mandíbulas y de pelvis, recuperados en estratigrafía. La ocupación de la cual proviene el material está fechada en el Holoceno tardío.
Análisis preliminar del conjunto arqueofaunístico de El Taco 19, sierras de El Alto-Ancasti, Catamarca
Authors: Moreno Enrique , Quesada Marcos
Published: February 2020

Históricamente las investigaciones arqueológicas han tendido a construir a las sierras de El Alto-Ancasti en términos de frontera, de espacio límite, entre los desarrollos del área valliserrana, frecuentemente vinculados a una tradición cultural andina y los de la llanura chacosantiagueña. (González y Pérez Gollán 1976; González 1977). A otro nivel, estás serranías, como en general todas las tierras altas que rodean el valle central de Catamarca y aledaños, como el de Ambato, fueron también pensadas, en función de los pastizales de altura que se extienden en los sectores cumbrales, como un ámbito especializado en el pastoreo de camélidos integrado a una geografía económica y política centrada en los valles.
Nuevos relevamientos de estructuras líticas y piedras paradas en las nacientes del río Sauce Grande (Partido de Tornquist, Provincia de Buenos Aires)
Authors: Panizza María Cecilia , Oliva Fernando , Sfeir Anabella , Oliva Camila
Published: February 2020

Dentro del conjunto de evidencias arqueológicas documentadas para el Sistema Serrano de Ventania, se destacan por su número, los sitios arqueológicos que presentan estructuras líticas y/o piedras paradas. Los estudios de este tipo de registro se inician tardíamente en la década del ‘90 (Madrid 1991a, 1991b; Oliva y Roa 1998, Roa y Saghessi 2004) profundizándose la sistematización de los mismos en el último lustro dado el riesgo inminente de deterioro y alteración al que se ven expuestos (Devoto et al. 2012, Oliva 2011, Oliva y Panizza 2010, 2012; Sfeir y Oliva 2012). Los datos obtenidos permitieron establecer su área de ocurrencia fundamentalmente en la zona centrooriental, sector que corresponde a los cordones serranos de la Ventana y de Pillahuinco.
Midiendo decisiones locacionales. Una aproximación a la evaluación de la defensibilidad efectiva de sitios arqueológicos fortificados
Authors: Parcero-Oubiña César
Published: February 2020

La fortificación de los espacios de asentamiento es un fenómeno ampliamente extendido en el registro arqueológico. Determinar la función y sentido de esa fortificación es a menudo un elemento clave en la caracterización social y política de los contextos en los que ocurre. En este trabajo se presenta un procedimiento de análisis basado en el empleo de SIG que, sobre una base mensurable, aporta elementos para la evaluación de las decisiones locacionales y constructivas que puedan estar detrás de la fortificación de los asentamientos. Se parte de plantear dos hipótesis principales: que la construcción de las estructuras defensivas siga una lógica efectivamente defensiva, o una monumental. Se definen una serie de factores mensurables que puedan relacionarse con ambas hipótesis: dónde y cómo, dentro de un poblado, sería esperable ubicar las defensas si se buscase un efecto defensivo, y dónde y cómo si se buscase un efecto monumentalizador. A través de un caso de estudio en un poblado de la Edad del Hierro en Galicia (NW de España) se muestra una implementación de este procedimiento, y la manera en la que se ha considerado la medición de variables que permitan responder a esas preguntas. El objetivo del trabajo es presentar la lógica y los detalles de un procedimiento analítico fácilmente aplicable con herramientas SIG estándar, antes que explorar a fondo las posibilidades interpretativas que se derivan de sus resultados.
Chenques en patagonia centro-meridional: análisis de los patrones de distribución espacio-temporales
Authors: Zilio Leandro
Published: February 2020

Los chenques corresponden a una forma de enterratorio humano característica en la Patagonia durante el Holoceno tardío final. Estos se caracterizan por hallarse demarcados superficialmente por una cobertura de rocas y estar ubicados, en general, sobre elevaciones del terreno. Las descripciones que se han realizado de los chenques por parte de viajeros e investigadores, llaman la atención por las similitudes o regularidades en su conformación y ubicación, a pesar de su amplia distribución tanto geográfica como cronológica. Se propone como hipótesis que estas regularidades habrían sido consecuencia de conocimientos y creencias compartidas por las poblaciones, a partir de circuitos de movilidad e intercambio que conectaban a los grupos en el pasado. En este trabajo se analiza el registro de chenques en Patagonia centro-meridional que cuentan con dataciones radiocarbónicas, con el objeto de reconocer tendencias espacio-temporales de los chenques.

Variabilidad en la explotación y procesamiento de ungulados en el sector centro-oriental de la Región Pampeana
Authors: Acosta Alejandro , Loponte Daniel , Mucciolo Leonardo
Published: February 2020

Se analiza la explotación de ungulados por parte de los grupos cazadores-recolectores que ocuparon el sector centro-oriental de la región Pampeana durante la fase final del Holoceno tardío (<2000 años AP). Para ello, consideramos las características eto-ecológicas de los principales taxa explotados (Lama guanicoe, Blastocerus dichotomus y Ozotoceros bezoarticus) y comparamos la información arqueofaunística procedente de dos sitios arqueológicos situados en dos de las unidades del paisaje que integran la región bajo estudio. A partir de los resultados obtenidos, mediante la aplicación de diferentes índices, se postulan distintas hipótesis con el fin de establecer y discutir similitudes y diferencias relacionadas con la importancia económica que adquirieron dichas presas y las modalidades utilizadas para su procesamiento y consumo.
