Biosensor technologies is an interdisciplinary science related to the development of biological and information sciences, based on the creation of devices with biocomputing components forming neural network structures, also used for the identification of animals. (Research purpose) The aim of the study is studying and structuring information on the use of biosensor devices and systems in livestock, find the possibilities for subsequent introduction into industry’s practice through effective engineering solutions of pattern recognition, adaptive management of animal behavior, etc. (Materials and methods) We have used methods of collection, study, systematization, analysis of scientific information obtained from livestock practices, expert assessments made in accordance with the technological regulations of the scientific-and- technical funds, patent and license sources, innovative developments of leading manufacturers of machinery and equipment for the beef cattle identification. (Results and discussion) Theory and practice of biosensor science in animal-based biomedical research proved that a balanced, workable system of biosensor control reaches the value of 1,0 e10 - 1,0 e12 of individual cells-sensors. The pulse time of the neuron of 2-5 milliseconds is enough for evaluation of the animal’s habitus, as well as speed of movement, body temperature. It is possible to determine information about the physiological condition of the animal: rut, fatness, location or identity of animal, quality of sperm, embryos, authenticity of origin and other parameters on selected DNA samples by using smart laser and ultrasonic biosensors that transmit these data to smart chips. The article shows that the linear biological parameters of the object obtained with the sensors can be converted by calculation into nonlinear ones, with further telemetry transmission of information to the animal’s biochip and stationary receiving software device. Biocalculation devices are able to calculate and control the change in live weight of animals of different breeds up to 6 months of age, adjusted for the variability of the trait. It was found that the coefficient of variation Cv reaches 1.5-2.5 percent, and as the animal grows, it reaches of 15-18 percent. (Conclusion) The solution of engineering problems in animal husbandry with the help of biosensors and sensors of a new generation depends on the biochemical nature of the recognition element (its action algorithm can be calculated). Biocomputing devices are capable not only to accept, but also to count and to control various parameters of animals. The use of engineering biosensor intelligent systems and neurocybernetic in animal husbandry expands the possibilities of the industry, makes them attractive to the manufacturer and gives a great economic effect.

Authors: Budnikov Dmitriy A.
Published: October 2020

Classical thermal methods of grain drying are characterized by high energy intensity. The study of grain processing modes using electrical technologies allows to reduce the cost of drying. When studying, it is necessary to take into account the technological requirements for the processed material, types of electrical technologies, and the operating mode of the intensifying equipment (constant, pulse, and others). (Research purpose) The research purpose is obtaining dependences of the energy efficiency of drying wheat grain using the energy of the microwave field for different states of the layer. (Materials and methods) A diagram of a laboratory installation has been used. Experimental studies were performed to determine the drying curves and the energy intensity of drying the layer of wheat grain. (Results and discussion) The two-factor experiment was conducted to determine the effect of the power of the field and the density of the grain mound on the energy intensity of the grain drying process. Article presents the required dependencies. (Conclusions) Data has been obtained as a result of an experiment on drying a grain layer located in a dense, fluidized and suspended layer under the influence of a microwave field at an initial grain humidity of 17 percent. It was found that the use of an ultra-high-frequency field in the process of drying grain crops is advisable when the humidity of the processed material is close to the standard one (17-18 percent for wheat). It was found that the use of an ultra-high-frequency field makes it possible to intensify the drying process when humidity is close to the standard by 3-4 times and reduce the overall energy consumption of the drying process in areas of humidity close to the standard by 20-40 percent. It was found that in order to increase the reliability of data, it is necessary to increase experiments on large-scale models that allow predicting the energy intensity of drying in industrial plants.

Published: October 2020

When repairing and replacing electrical wiring in enterprises, the main difficulty is the lack or poor quality of documentation, plans for conductors laying. Distinguishing wires (cables) and their cores by the color of the shells or using tags attached to the ends is difficult if the shells have the same color and there are no tags. Devices and technical solutions used to identify wires and cables do not allow recognizing conductors without breaking the electrical circuit, removing insulation, and de-energizing the network. Searching for the right conductor is a time-consuming operation. (Research purpose) The research purpose is developing a new microcontroller device for identifying wires using an acoustic signal. (Materials and methods) Literature sources has been searched for devices for conductors identifying. (Results and discussion) The article proposes a method that involves feeding an acoustic signal to a wire at one point and capturing it at another, in order to recognize the desired wire. The article presents results of comparison of the developed microcontroller device for identifying conductors using an acoustic signal with known devices and methods for conductors recognizing. (Conclusions) The article reveals the shortcomings of existing methods and means of identifying wires and cables. Authors performed a theoretical calculation of the sound pressure in the conductor at a given distance. The article presents the calculation of speed of acoustic waves in conductors with different types of insulation. Authors designed a microcontroller device for identifying conductors using an acoustic signal and tested it. It was determined that the device increases the safety of work, reduces the cost of operating internal wiring and identification time; eliminates the violation of wire insulation, the need to disable electrical receivers. The convergence of theoretical calculations and experimental data was shown.

Published: October 2020

Creating and maintaining a microclimate in animal housing is an energy-intensive technological process that consumes up to 70 percent of the thermal energy consumed on cattle farms. Improving heating and ventilation systems aimed at reducing energy consumption is an urgent task. (Research purpose) The research purpose is to analyze the theoretical models for calculating air curtains and evaluate the possibility of their use for agricultural production facilities and to identify promising directions in the design solutions for thermal air curtains aimed at rural consumers. (Materials and methods) The article considers the theoretical justification and calculation of air curtains. The authors studied the physical model of interaction of air jets in openings, which serves as the basis for mathematical calculation of air curtains in engineering practice. The article describes the features of using the models for calculating air curtains for agricultural objects and the energy parameters of the curtains depending on the design characteristics and external environmental factors. (Results and discussion) The effect of the air curtain on the energy characteristics of the room has been studied. It was found that it is necessary to determine the type of air curtain that is optimally suitable for protecting the gate opening, with or without heating the air curtain. Authors have found that the engineering methods of calculation are based on different experimental data, which leads to a discrepancy in the results of evaluating the effectiveness of the designed curtain, overestimating its energy intensity and power. The calculation of heat curtains, operating modes should be carried out taking into account the variable effects of external physical factors, the equipment should correspond to a specific room. (Conclusions) The use of air curtains reduces or eliminates the penetration of external cold air into the room through the openings of external gates, requires a smaller volume of air supplied by the curtain, compared to the mass of the incoming air flow.

Resumen: Puerto Madryn, ciudad patagónica en expansión, es un destino elegido por migrantes senegaleses en el verano, para mejorar las ganancias del comercio ambulante, una práctica laboral que genera conflictos y negociaciones con sectores de la sociedad receptora. “Para entender las relaciones urbanas, hay que comprender las burocracias que las rigen y los medios de comunicación que las representan” sostiene Perelman (2017: 13). En esta etnofotografía indago en el modo articulado en que Inspección municipal y el periódico El Chubut custodian un modelo de ciudad de servicios y turismo dominante en Puerto Madryn, “amenazado” con la llegada de migrantes negros que venden en el sector costanero y representan una “anomalía socio-urbana” que los sectores dominantes buscan corregir, aplicando mecanismos de control social del campo de la contravencionalidad y de la objetivación discursiva. La disputa por el acceso a la ciudad también involucra decisiones y resistencias que los migrantes ejercen según las posibilidades y haciendo un uso estratégico de los recursos disponibles.Palabras clave: Ciudad patagónica argentina.

This is a labor practice that lead to conflict and negotiations with sectors of the receiving society. "To understand urban relations, we must understand the bureaucracies that govern them and the media that represent them" says Perelman (2017: 13). Through an ethnophotography I analyze the articulations between the Municipal Inspection and the newspaper El Chubut to guard a dominant city model of services and tourism in Puerto Madryn. This model is “threatened” since the arrival of black migrants who sell in the coastal sector and represent a “socio-urban anomaly” that the dominant sectors seek to correct by applying mechanisms of social control, of the field of contraventionality and discursive objectification. The struggle over access to the city also involves migrants’ decisions and resistance according to existing possibilities and making an strategic use of available resources.Keywords: Argentinian Patagonian city.

Um olhar sobre o cinema pelas lentes do imaginário
Authors: Fantinel Danilo
Published: October 2020

Resumo: Pesquisas acadêmicas brasileiras e europeias apresentem convergências entre os estudos do imaginário e as teorias do cinema, porém o pensamento sobre as relações entre os conteúdos simbólicos e as produções cinematográficas não está refletido em ampla bibliografia no formato livro. Ainda assim, entre obras consagradas como O cinema ou o homem imaginário, de Edgar Morin, ou O significante imaginário, de Christian Metz, trabalhos menos conhecidos, como Le cinéma et l’imaginaire, de Michel Serceau, podem ser úteis na compreensão da influência do imaginário sobre a sétima arte.Palavras-chave: Imaginário, imagem, cinema, pesquisa, teoria LOOKING AT THE CINEMA THROUGH THE LENSES OF THE IMAGINARY Abstract: Brazilian and European researches have been converging imaginary studies and film theory over the years. Nevertheless, there is a lack of books on the relations between symbolic meanings and film productions. Despite this, amongst well known publications as Edgar Morin’s Le cinéma ou l'homme imaginaire or Christian Metz’s Le signifiant imaginaire, lesser-known works like Michel Serceau’s Le cinéma et l’imaginaire could be useful to comprehend the 7th art under the influence of the imaginary.Keywords: Imaginary, image, cinema, researche, theory
A Cidade de Manaus a partir da Etnografia do Circuito do “RAP AM”
Authors: Norberto Rafael Branquinho Abdala
Published: October 2020

Resumo: Levo a cabo neste artigo a proposta de apresentar a cidade de Manaus a partir da etnografia do circuito do “Rap AM” - como MCs/rappers, DJs, beatmakers e produtores musicais reconhecem o circuito da música Rap em Manaus -, trazendo interpretações e narrativas etnográficas fruto do encontro intersubjetivo com os colaboradores desta pesquisa de doutorado (2016-20) realizada em quase oito meses de trabalho de campo na referida metrópole amazônica. Parto do amparo teórico/teórico-metodológico interdisciplinar  (etnomusicologia/antropologia) através dos paradigmas da etnografia da música/etnografia urbana enfatizando três eixos centrais da pesquisa: 1. a cidade de Manaus a partir da lente do etnógrafo; 2. o olhar do “Rap de quebrada” e suas interpretações da cidade ao empregar as categorias “periferia”, “quebrada” e “favela”; 3. o olhar do “Rap regional” e a sua demanda por uma “Manaus étnica”. Ressalto as potencialidades desta etnografia ao propor outros olhares/escutas das/nas cidades amazônicas, ao passo que problematizo o imaginário comum em torno de uma Amazônia predominantemente “rural”.Palavras-chave: Música Rap.

Antropologia Urbana. MANAUS (A METROPOLIS FROM AMAZON REGION, BRAZIL): PERSPECTIVES FROM THE ETHNOGRAPHY OF “RAP AM” CIRCUIT Abstract: I present on this paper Manaus (a metropolis from Amazon region, Brazil) from the ethnography of “Rap AM” circuit - how MCs/rappers, DJs, beatmakers, and music producers recognize the Rap music circuit in Manaus -, bringing to light both interpretations and ethnographic narratives from the intersubjective encounter with collaborators of this PhD research (2016-20) carried out in almost eight months of fieldwork. I based myself in the interdisciplinary encounter of ethnomusicology and anthropology through the paradigms of music ethnography and urban ethnography. I emphasize the following issues throughout the paper: 1. Manaus city from the lens of the ethnographer; 2. "Ghetto Rap" subgenre and its interpretations of the city through categories such as “periphery” and “favela” ("slum area"); 3. “Regional Rap” subgenre and its demand for an “ethnic Manaus”. I underline potentialities of this ethnographic research for proposing other views and points of listening of and in Amazonian cities, and for problematize the common imaginary around a predominantly “rural” Amazon.Keywords: Rap Music.
