The aim of the article is to improve the quality and productivity of sorting by developing a method and an intelligent device for automatic recognition and inspection of substandard potato tubers. The article describes a prototype of an automatic sorting machine designed to recognize external defects in potato tubers and automatically inspect them with a jet of compressed air. The recognition process consisted of three main modules: segmentation, tracking a potato moving in a frame along a conveyor belt, and classification using a trained artificial neural network. For the segmentation of potato tubers against the background of the transporting conveyor in real time, a method based on the calculation of the color threshold was used. The centroid tracking algorithm was used to track moving potato tubers. To train the artificial neural network, we created our own dataset consisting of images of marketable and defective potato tubers. A prototype of an automatic sorting machine has been developed, which is based on the concept of intelligent data analysis, according to which the images of potato tubers obtained from a video camera are processed and formed into images with subsequent recognition and signaling to the executive device of the automatic inspection system in the form of a single pulse signal when determining the tuber as substandard.

The rate of the feed velocity and specific load in the air separator are interrelated and require a rational approach to their choice, because reducing the rate of velocity increases grain flow thickness, which adversely affects the efficiency of grain separation in the separation zone, but limits separator performance. Based on the research of many authors, it was concluded that the feed velocity of grain material into the pneumatic separation channel should be in the range of 0.4… 0.6 m/s. Taking into account that using a feeder unit for multilevel grain input, the total thickness of grain flow is divided by the number of the involved levels of input. The main condition is to ensure a single layer of grain feed at the velocity at which the most intense release of light impurities. Therefore, the purpose of the study is to identify rational parameters of the guide gravitational surface of the feeder unit with the provision of appropriate performance characteristics of the grain flow during its multilevel feeding into the pneumatic separating channel. As a result of experimental research, the dependences of the modes of movement of grain material on the gravitational guide curve on its main parameters, namely, the length of the acceleration section Lp, its angle α and the radius of the arcuate section r. On the basis of the carried-out research parameters of a gravitational guide surface at which a single-layer mode of movement of grain material for a range of specific loadings is reached are established qB = 250 – 500 kg/hour. Accordingly, for the conditions of movement of grain material with a thickness of one grain with the velocity of feeding into the pneumatic separation channel vв = 0.5…0.6 m/s, the rational parameters of the guide gravity curve for cereals with the internal friction coefficient φтер = 0.47…0.73 there are: the length of the acceleration section Lp = 0.2 m, the angle of its inclination α = 33° and the radius of the arcuate section r = 0.15 m.

Published: April 2021

The article analyzes resource scheduling algorithms in a distributed computing environment. The main task that distributed computing technologies solve is providing access to globally distributed resources using special tools. The complexity of managing global resources is due to the fact that access to the necessary data can occur on different computers. In addition, global distributed computing networks formed from autonomous resources can change their configuration dynamically. Resource management in heterogeneous distributed computing systems requires the search for new models of computation and resource management. Analysis of recent research and publications has shown that currently the implementation of resource planning in a distributed computing environment requires the search for new approaches and new algorithms. Most of the work on resource planning methods in a distributed computing environment is used to solve specific tasks related to specific applications and therefore cannot be universal. The aim of the work is to analyze resource planning algorithms in a distributed computing environment in order to find methods and algorithms for resource management in a problem-oriented distributed environment, taking into account the specifics of individual tasks and use the possibility of parallel execution of different tasks. The analysis of resource planning algorithms in a distributed computing environment shows that to date, a large number of planning algorithms focused on use in a distributed computing environment. But often such algorithms do not take into account the problem-oriented specifics of the environment, and this affects the efficiency of planning. In this regard, a promising area is related to the development of resource planning algorithms in a distributed computing environment, which would create an efficient and effective resource planning system.

To create a database and systematize the seeds of samples of small-seeded crops, it is necessary to determine the patterns of influence of morphological parameters on their physical and mechanical properties. The development of the latest technologies and technical devices for cleaning and separation is possible due to the understanding of the characteristic morphological parameters for each of the small-seeded crops. The aim of the research is to determine the physical and mechanical properties of the seed material of small-seeded crops (mustard, flax, ryegrass, rapeseed), necessary to increase the efficiency of their cleaning and separation processes. To achieve this goal, a plan of experimental research was developed, which provided for the determination of physical and mechanical parameters of seeds of small-seeded crops, namely: indicators that characterize the flowability of seeds (angle of natural bias); frictional properties of seeds (static coefficient of friction); porosity (density) and density; size and mass characteristics of seeds (length, width, thickness, effective diameter, weight of 1000 seeds). It is established that the physical and mechanical properties of seeds of small-seeded crops are greatly influenced by its humidity. With increasing humidity, the performance of the test material increases. This is due to the fact that with increasing humidity, the shape of the seed almost turns into a spherical, which, in turn, leads to an increase in the curvature of the surface and reduce the points of contact between the seeds. As a result, the angle of natural inclination increases. The coefficient of friction of seeds of small-seeded crops depends on the roughness of the friction surface and decreases with increasing humidity. This is due to the fact that with increasing humidity decreases the forces of molecular attraction of the seed coat to the surface of the material. Seed density increases with increasing humidity. From this we can conclude that the absorption of moisture by the investigated material increases the total weight of the seed, and as a result - increases its specific weight.

The article presents considerations for creating conditions for the intensification of the process of grain separation by geometric features. The review of constructions and the analysis of work of known sieve surfaces from a position of possibility of maintenance of high indicators of technological efficiency at the expense of acceleration of orientation of particles concerning sieve apertures is carried out. It is established that the most favorable orientation conditions are provided by the surfaces formed by longitudinal elements of small cross-section of streamlined shape, which minimize the possibility of placing particles on them in positions of stable equilibrium. Theoretical possibilities of increasing the living cross-sectional areas and live cross-sectional coefficients of sieve canvases without cross-sections are revealed. The dependences of the total width of the longitudinal sections and the coefficient of the living cross section of the sieves on the width of the longitudinal sections for different sieves are given. This makes it possible to visually assess the need to increase the living cross section of the sieves by reducing the width of the longitudinal sections that form them. A significant reduction in the width of the partitions is possible due to the use of new materials - braided cords made of ultra-high molecular weight polyethylene type Spectra / Dyneema, which provide high mechanical strength and wear resistance with «absolute» inextensibility.

Published: April 2021

In agriculture and feed production, seeds and grains of various crops that require cleaning and separation are used as sowing material and raw materials. For seed and grain cleaning and separation the separators of different type are used. During operation, these separators take into account the physical and mechanical properties of the raw material. The article proposes the design of bulk material separator of scissor type, which has small dimensions and is easy to maintain. The efficiency of separator depends on the uniformity of the bulk material loading on the sieve surface. Therefore, substantiation of rational parameters of separator is an extremely important task. So, the aim of the study is to model the loading process of bulk material from the unloading hole of the hopper on an inclined flat sieve of the scissor-type separator, which performs oscillating motion. The proposed mathematical model of the bulk material loading from the hopper to the separator sieve allows us to determine the trajectory of the particle falling and to describe the position of the sieve, which changes due to the rotation of the eccentric. Also, modeling allows us to justify the rational parameters of the separator, taking into account the kinematic mode of its operation. Under these parameters, a layer of material of the same height will be formed on the sieve, which will provide favorable conditions for the separation process. In addition, the mathematical model allows us to determine the rational parameters of the relative position of the hopper and the sieve. In this case the entire surface of the sieve is used effectively.

The aim of the research is to increase the efficiency of harvesting the non-grain part of the sunflower crop for energy purposes by developing technology and substantiation of technical means. The analysis of sunflower harvesting technologies is carried out; the method of harvesting the crushed mass of the non-grain part of the sunflower crop with the formation of windrows of high linear mass at the edge of the field is substantiated. The results of laboratory field research of harvesting, selection and pressing of the crushed mass of the non-grain part of the sunflower crop are presented. Directions of improvement of the baler for harvesting of a non-grain part of sunflower harvest are noted. The constructional-technological scheme of the trailed hopper and windrow-former to the combine harvester for formation of windrows of a non-grain part of a crop of sunflower with the increased running weight is offered. The results of laboratory field studies confirmed the hypothesis of the possibility of selecting the rolls of the crushed mass of the non-grain part of the sunflower crop with a running weight of more than 20 kg per meter at a level of losses not exceeding 20%. The efficiency of harvesting the non-grain part of the sunflower crop for energy purposes can be increased by collecting the crushed mass passed through the combine harvester in a trailed digger and forming rolls with high running weight at the edge of the field for drying and subsequent selection by serial balers. It is established that at the level of yield of sunflower seeds within 3 ton per ha the volume of harvesting by the combine harvester of the crushed weight of non-grain part makes 7.5-8.5 center per ha. When picking with a baler, rolls with a density of 75-90 kg per m3 were formed at an average humidity of 23%.

Published: April 2021

The regularities of specific loading distribution of loose mixture on the area of a working surface of the inclined tray are established in the work. The studies were performed on the experimental setup consisting of a storage hopper and inclined flat trays of different lengths. The material of the study was a grain mixture of winter wheat variety "Myronivska 30". The magnitude of the load was determined using a receiving device, which allowed to obtain the specific load distribution on the width and length of the tray and over time. The specific loading of the tray is uneven in the area of the working surface: the central section is overloaded, and the wall is underloaded. The largest deviations of the specific load at the inlet of the tray, but with length they decrease, approaching a uniform distribution. The specific load profile across the width of the tray is asymmetric and has a local extremum. As the tray length increases, at the certain initial speed and angle, the specific load decreases and the mixture flow slows down. With a constant supply of material from the hopper, there is a gradual accumulation of the mixture in the tray, compaction and growth of the layer, which leads to complete cessation of flow. Uneven loading of the tray occurs due to uneven supply of material from the storage hopper, in which the movement begins. The initial feed varies across the width of the tray and over time, and the nature of the specific load profile formed at the entrance to the tray is preserved for almost its entire length. The movement of the mixture flow in the inclined tray is non-stationary, the specific load varies significantly over the entire surface area and largely depends on the initial conditions of movement. The obtained regularities of specific loading on the working surface area of the tray can be used in the calculation of the modes of loose mixtures movement and substantiation of the equipment parameters for loading the working bodies of machines.

The article compiled and solved a system of differential equations of motion of a material point along a porous (air-permeable) surface, which is inclined at an angle to the horizon. Based on the analysis of solutions to this system of differential equations, it is proposed to change the speed of grain movement by the frequency of oscillations of the support surface, the angle of inclination of the support surface to the horizon and the coefficient of friction. Also, the graphical dependences of the speed of grain movement on the angle of inclination of the support surface to the horizon, the coefficient of friction and the frequency of oscillations were obtained. The possibility of decelerating the vibration movement of grain by an air flow, which is fed from the bottom of the porous support surface against (at an angle) the direction of grain movement, as well as using an asymmetrically corrugated support surface with vertical perforations, is theoretically substantiated. A linear regression dependence of the change in the vibration displacement speed has been experimentally determined, which makes it possible to form the required speed mode of vibration displacement of grain by changing the parameters: the inclination of the vibrating plane is 50 ÷ 90, the vibration frequency is 45 ÷ 55 s-1, the air flow speed is 0.1 ÷ 2 m/s in optimal operating modes. installations for high-intensity heat treatment of grain with a vibratory conveyor.

Este artigo apresenta uma análise sobre as contratações diretas dispostas na Lei n° 8.666/1993 e na Lei n° 13.979/2020, durante a pandemia Covid-19. Dito isso, ele tem como objetivo investigar quantos foram os gastos efetuados pelo Estado do Pará nesses últimos 10 anos em contratações diretas realizadas, especialmente, através da dispensa de licitação. Trata-se de uma pesquisa bibliográfica sobre o tema, que buscou contribuir e salientar a compreensão dos aspectos que abrangem as compras públicas. Nesse ínterim, ela ainda se caracteriza como um estudo de caso que objetivou identificar os valores gastos pelo governo em compras, efetuados apenas pelo estado do Pará. Para a realização da pesquisa, os dados coletados foram obtidos através dos portais de transparência de compras “compraspara.pa.gov.br” que dispõe dos processos de compras públicas efetuados pelos órgãos e o “transparenciacovid19.pa.gov.br” associado as compras e contratações emergenciais referentes ao Covid–19, sendo, posteriormente, realizado uma análise de conteúdo do tema proposto. Em suma, de acordo com os resultados, foi possível verificar que houve uma antecipação do Estado do Pará em gastar 202 milhões em compras logo no início da pandemia quando se havia poucos dados científicos como respaldo para as decisões políticas, o que até o final do primeiro semestre de 2020 esse valor já havia alcançado 419 milhões. Gastos esses que não evitaram que o estado do Pará apresentasse o maior índice de casos notificados e óbitos confirmados dentre as unidades federativas, ultrapassando até o Estado de Minas Gerais que, se comparado, possui o dobro de habitantes.

No ensino da leitura na contemporaneidade, a hermenêutica é uma prática que diz respeito a interpretação do discurso em diferentes contextos de produção de sentidos. Compreender e interpretar são processos indissociáveis nesta prática. Originando-se de tempos em que havia a necessidade de uma técnica que esclarecesse os escritos sagrados, e as leis jurídicas, a leitura hermenêutica passa por uma longa trajetória que a consolida em tempos contemporâneos como uma prática universal. Visto a necessidade de incentivar o aluno à leitura, este artigo tem por objetivo apresentar os diferentes aspectos conceituais da hermenêutica, centrada na questão da produção de sentidos e na intersubjetividade no ensino da leitura. Em seus aspectos metrológicos, a pesquisa sobre hermenêutica tem por finalidade evidenciar o valor da interpretação criativa (que dá liberdade ao aluno para argumentar sobre o texto), a fim de que a mediação do ensino da leitura seja diferenciada. Este trabalho foi realizado através de uma metodologia baseada na pesquisa teórica, que se propôs a apresentar os diferentes pensamentos sobre a leitura, a interpretação e a hermenêutica. Com base nos autores referenciados, a prática hermenêutica oferece à educação, orientações que promovem um entendimento de como o intérprete pode chegar a real compreensão do texto lido, identificando gêneros e relacionando suas semelhanças e diferenças, no que diz respeito a sua linguagem, a sua estrutura e o seu funcionamento social. A aplicação da leitura hermenêutica em sala de aula estimula a presença e o envolvimento dos alunos na busca pelo desvendamento dos segredos presentes no texto, segundo a visão do outro (escritor). Desta forma, o aluno é incentivado a identificar e a divulgar a sua interpretação sobre o texto e os sentidos atribuídos a ele durante a leitura, de modo a compreender este cenário, não como a própria realidade, mas como mais uma dimensão da realidade.

Le trasformazioni occorse nel tempo nella cultura del sistema penale e peni-tenziario hanno inciso sulla identità professionale dei professionisti della funziona-lità giuridico-pedagogica. Il passaggio ad una cultura "rieducante" del sistema-carcere nel secondo dopo-guerra ha messo in luce una nuova identità, un nuovo ruolo cui non sempre si accompagnano nuove consapevolezze e pratiche educative. Il contributo intende ricostruire l'identità di ruolo del funzionario giuridico-pedagogico all'interno delle professioni educative e formative. A tal fine sono utilizzati elementi di rappresentazioni degli attori organizzativi e prospettive identita-rie legate al modo in cui ogni istituto costruisce il senso della professionalità giuridi-copedagogica con i dispositivi in uso e alimenta la cultura del lavoro educativo in carcere. Il contributo si conclude con alcune riflessioni sulla configurazione del funzionario giuridico-pedagogico come "specialista del trattamento" in relazione alla sua capacità di gestire ogni elemento del proprio lavoro in chiave educativa e di co-struire in autonomia il senso del suo ruolo professionale.
Come valutare le biografie professionali? L'importanza formativa ed educativa delle Narrative Skills nei contesti professionali
Authors: Togni Fabio
Published: April 2021

Il saggio, partendo dalla diffusione delle Professional Bio, con un taglio di se-miotica pedagogica, indaga il valore formativo della narrazione mettendo in evidenza i suoi aspetti tecnico-formali, i suoi espedienti e i suoi schemi principali. Questi tre elementi vengono analizzati per evidenziare il profilo delle Narrative Skills degli autori di questi testi, di coloro che sono chiamati a valutarli e, infine, di coloro che hanno compiti di formazione nei contesti professionali e intendono utilizzare strategie narrative. In conclusione, viene proposto uno strumento per la va-lutazione della competenza narrativa in tutti i contesti in cui essa si manifesta.
Il mercato del lavoro dei professionisti dell'educazione e della formazione
Authors: Gasca Paolo
Published: April 2021

Ci troviamo oggi a combattere una guerra contro un nemico invisibile, che ha impattato pesantemente non soltanto sulla dimensione familiare e sociale di ciascuno, ma anche sulla sfera lavorativa. Il contratto psicologico che lega gli individui e le organizzazioni è stato stravolto e ridisegnato, lasciandosi alle spalle valori quali "sicurezza" e "appartenenza". Quello che si prospetta è un futuro del tutto nuovo, in cui i concetti di "habitat professionale" e di "work-life balance" assu-mono nuove accezioni e in cui appare necessario riscoprire il rapporto fra azienda e persone, per dare vita a un nuovo "umanesimo aziendale" che recuperi la centra-lità della persona e permetta all'individuo di esprimere se stesso e tutte le proprie potenzialità. Come? Attraverso modalità maieutiche capaci di sviluppare nuove capacità e qualità individuali e di accompagnare le persone in un ineludibile riposi-zionamento professionale e, soprattutto, personale. Occorre passare dall'obiettivo di gestire a quello del "prendersi cura" delle persone dando un nuovo senso, una nuova prospettiva al contratto psicologico. E qui entrano in gioco i professionisti della formazione, la cui sfida è, oggi più che mai, quella di dare vita a un nuovo pensiero gestionale, a nuove idee, e di sostenere le persone in un percorso di crescita che permetta loro di confermarsi come il vero differenziale di competitività.
The Effect of Sense of Movement in Audiovisual Media: A Study on Kineticism as a Formant of Expression in Globo News’ Institutional Motion Sequence Intolerância
Authors: Lopes Davi Médola Ana Silvia , Da Silva Pereira Henrique
Published: April 2021

This article analyzes the Brazilian cable television channel Globo News’ institutional motion sequence Intolerância. Israeli designer, Noma Bar, illustrated and directed Intolerância, which reveals in its discursive structures how the gaze of a Latin American country hegemonic media on the identity conflicts between West and East is aligned with Western powers. In the wake of Floch’s theoretical developments in plastic semiotics and Bergson’s postulations on the mechanism of the philosophy-centered filmmaking movement, this study aims to consider kineticism as a constitutive formant of visuality in audiovisual texts. The analyzed motion sequence is a notably exemplary object of establishing such hypothesis.
In vitro activity of Indian almond (Terminalia catappa) leaf crude extracts against selected dermatophytes
Authors: Colendres Roxanne Joy , Pradera Carl Leonard
Published: April 2021

Fungal infections caused by Trichophyton mentagrophytes, Aspergillus fumigatus , and Malassezia pachydermatis are among the major contributors to multisystemic health problems such as dermatitis, otitis, and respiratory disorders among humans and animals. This study was conducted to determine the in vitro antifungal activity of Terminalia catappa leaf crude aqueous and ethanolic extracts against these fungal pathogens by measuring the zone of inhibition (ZI) using the agar well diffusion technique. Qualitative phytochemical screening tests were also performed to determine bioactive compounds present in the plant extract.
Results show that the plant’s crude aqueous (CAE) and ethanolic extracts (CEE) were found to be effective against all test fungi. M. pachydermatis showed susceptibility towards CAE and CEE from T1 (100%), T2 (75%), T3 (50%) and T4 (25%), with the highest mean ZI of 18.33mm and 13.33, respectively. On the other hand, T. mentagrophytes was inhibited by CAE and CEE at T1 (100%), T2 (75%) and T3 (50%) with the highest mean ZI of 9.67mm and 10.33mm, respectively. At the same time, it was observed that A. fumigatus had reactive sensitivity towards CAE and CEE at T1 (100%) and T2 (75%), with the highest mean ZI of 9.33mm and 10.33mm, respectively. Moreover, phytochemical tests showed that the plant’s leaf crude extracts contain alkaloids, saponins, and tannins, which could potentially inhibit fungal growth.

Цель исследования. Разработка способа психологической коррекции эмоционального состояния беременной женщины перед амбулаторным стоматологическим лечением.
Объекты и методы исследования. В группу исследования вошли 92 женщины, группу сравнения составили 93 беременные пациентки, обратившиеся к врачу-стоматологу по направлению ведущего акушера-гинеколога. Определяли тревожность пациентов по шкале Спилбергера-Ханина и темперамент тестированием по Айзенку. В зависимости от типа темперамента с целью снижения уровня ситуативной тревожности использовали рациональную психотерапию, используя: объяснение и разъяснение; убеждение; переориентацию; психогогику. У пациенток группы сравнения в речи врача использовалось лишь вежливое и внимательное обращение.
Результаты исследования и их обсуждение. Снижение уровня ситуативной тревожности по Спилбергеру-Ханину у беременных женщин от исходного в первом триместре на 16,8% ±1,6, во втором на 20,5 ±2,5% и устойчивый уровень полезной тревожности в третьем триместре в сравнении с контрольной группой. По результатам работы был разработан и зарегистрирован «Способ коррекции эмоционального состояния беременной женщины при проведении стоматологических вмешательств» (патент № 2571323 от 23 ноября 2015 г.).
Заключение. Применение разработанного способа психологической коррекции тревожности беременной женщины методами поведенческой психотерапии перед проведением стоматологического вмешательства повышает безопасность стоматологического лечения.

Percursos e Geografia: Uma reflexão sobre o trabalho de campo
Authors: De Castro Lívia Simões
Published: April 2021

Este trabalho propõe uma reflexão sobre o percurso enquanto noção fundamental para os trabalhos de campo de Geografia na educação básica. A Geografia possui uma longa tradição em construir conhecimento a partir do deslocamento no espaço e o trabalho de campo é, atualmente, uma das formas mais difundidas. A compreensão desenvolvida neste artigo acerca do trabalho de campo, o considera enquanto um percurso, ou seja, um sistema de lugares, um conjunto articulado de paradas e deslocamentos, em que a associação sequenciada destas paradas compõe uma narrativa. Com o intuito de analisar como a noção de percurso pode ser aplicada aos trabalhos de campo, acompanhamos algumas práticas realizadas por professores de Geografia da educação básica. A análise desses percursos demonstrou a importância do trabalho de campo na construção de narrativas e na apresentação de determinados conteúdos sobre os lugares.

Enclave de natureza rodeado por asfalto e concreto: trabalho de campo na cidade de Águas Claras-DF e os componentes físico-naturais
Authors: Farias Ricardo Chaves de , Cunha Leonardo Ferreira Farias da
Published: April 2021

Esse texto é fruto de uma prática pedagógica realizada pelo professor de Geografia com uma turma de Sétimo Ano do Ensino Fundamental - Anos Finais, na cidade de Águas Claras - DF. Trata-se de um Trabalho de Campo no espaço ao redor da escola, realizado a partir de uma mediação didática processual e organizada em três etapas, de modo a permitir a problematização (pré-campo), sistematização (campo) e síntese (pós-campo). Utilizou-se um caderno de campo organizado pelo professor para o registro de informações e interação com espaço.  Delimitou-se quatro pontos de exploração, na então denominada, Unidade Territorial de Aprendizagem. Entre eles, utilizou-se o Parque Ecológico da cidade para a construção de conhecimentos vinculados à dinâmica físico-natural presente, embora ocultada pelos prédios ao redor. Constatou-se que o espaço escolar pode ser aproveitado como ambiente para a realização de trabalhos de campo e que a mediação didática é um método eficiente para a construção de conhecimentos, a partir de um protagonismo dos estudantes.
Uma geografia emocional antirracista na sala de aula
Authors: Lima Ivaldo
Published: April 2021

Neste texto, aborda-se o domínio socioemocional com vistas à sensibilização moral do antirracismo por meio da educação geográfica escolar. O objetivo é apresentar as possibilidades de as competências e habilidades socioemocionais enriquecerem o ensino-aprendizagem da disciplina geográfica, à luz dos debates contemporâneos sobre as geografias emocionais. Para tanto, é ensejado um debate sobre a categoria Outro visando à inserção dos debates no âmbito da relação formada entre geografia e ética. A emoção moral da empatia é tomada como mote metodológico para a evidenciação do potencial didático-pedagógico das competências não-cognitivas. Por seu turno, o exemplo da arte pública do grafite, especificamente expressa na imagem de Marielle Franco, situa o debate ensejado na dimensão empírica do espaço urbano.
