Published: August 2020

The use of algorithms is a necessary activity for the design and construction, of any mobile robot. This study proposes an algorithm for future farm applications. Fertilization is an aspect that represents a third of the production costs. Robotics applied to agriculture, although in Mexico it is in the early stages of its development, the productive greenhouses are progressively automatized. Therefore, it is necessary to propose new automation strategies in the sector. As part of a stage of design and modeling of a virtual robot, this project proposes an algorithm of a 3D virtual robot prototype that allows visualizing and positioning in the 2D plane and thus having preliminary simulations for the subsequent construction of the Robot prototype.

Authors: Moreno-Zacarías Pedro Eduardo , Ramos-Dueñas Flor Del Carmen
Published: August 2020

Using natural extract of epazote (Chenopodium ambrosioides L.), has shown to control phytopatogenic fungi (P. Aguilar et al., 2013; y J. Black Solis et al., 2017). One mililiter of ethanolic extract at concentrations of 25%, 50%, 100% diluted on sterile distilled water (V:V) has been used to inhibit micelial developement of Fusarium oxysporum, and Fusarium solani, added to PDA Petri dish under a completely randomized experimental design, a statistical analysis was carried out by means of an ANOVA and comparison test of means with Tukey´s multiple range. After eight days of incubation, the outstanding inhibit effect has been observed with 100% and the average diameter of colonies was 62 mm., has been measured on both fungi species. In contrast, 62 mm., and 61 mm., was observed on F. oxysporum and F. solani respectively, and a statistical effect was observed (p≤0.05). With 25% and 50%, micelial inhibit developement has been measured, but no statistical differences between concentrations has been calculated (p≥0.05) for both fungi. The results suggest that ethanolic extract of epazote could be used to control both phytopathogenic fungi.

Published: August 2020

The objective of the present work was to offer an in vitro propagation alternative for the Oncidium sphacelatum orchid through the evaluation of the response to the crop in different concentrations of sucrose and the nutrient medium of Murashige and Skoog. Initially the seeds were sown in this culture medium at 100% of their concentration with the addition of 3.0% sucrose, once formed the protocorms the response to the application of different sucrose concentrations was evaluated (3.0, 2.25, 1.5, 0.75 and 0%) and of the nutrients of the culture medium (100, 75, 50, 25 and 0%) under a completely randomized experimental design of eight treatments with four repetitions. The analysis of variance showed statistical differences between treatments for the formation of buds in the protocorms, number of leaves per bud, plant height, root length and formation of pseudobulbs in the shoots. The highest outbreak formation in the protoorms was observed in treatments with 3.0% sucrose and nutrient concentrations at 50 or 25%. For the growth of the leaves and the root the concentration of 3.0% of sucrose was required combined with the concentrations of nutrients at 25, 50 and 100%. The formation of pseudobulbs in the outbreaks only occurred in the treatment with 3.0% sucrose combined with the 25% nutrient concentration.

Strategic planning (PE) has played a very important role in the development of formal alternatives to improve organizational performance in small and medium enterprises (SMEs). The following research aims to analyze the knowledge and application of SMEs in the city of Cancun, Quintana Roo with respect to PE. A quantitative, descriptive and transversal approach was carried out. 614 managers, businessmen or SME managers participated, who voluntarily supported us referenced by students who carried out their professional practices in the period May-August 2018, January-April 2019 and May-August 2019. The information was obtained through of an instrument of own elaboration. From the results it was found that 67.4% of SMEs do not know what PE is. An important aspect to highlight is that 73.6% of SMEs do not consider training as a strategy for innovation and growth of their business. Although many of the SMEs have several years of operation, 53.6% of them do not have any element of organizational identity, Organizational Philosophy (mission, vision or values). It is concluded that SMEs are willing to consider a training plan that suits their needs as long as it does not mean unnecessary expense. On the other hand they know the importance of having an administrator with the necessary skills to adapt to changes in consumers and the global market.

Published: August 2020

Pseudotsuga menziesii (Mirb.) Franco is a species of economic and ecological importance for Mexico. Several actions have been implemented for its ex situ conservation. However, the lack of characterization data is a limiting factor in genebanks. In this study, morphological characteristics and seed germination traits were evaluated in 12 accessions of P. menziesii from Tlaxcala and Puebla. Fifteen seed variables, germination percentage (PG), days to germination (DG) and radicle growth (CR) were measured in 100 seeds (four replicas of 25 seeds each) per accession. A principal component analysis, a cluster analysis and the estimation of the relationship between seed variables and germination traits were performed. The variables that had largest influence on the distribution of morphological variation were: LA, ASC, AS and AA/AS. The accessions were distributed in five general groups according mainly to their geographical origin. For some accessions, PG and CR had a direct relationship with seed size variables. These results showed the presence of variation and the influence of seed morphology on the germination of the evaluated accessions.

Published: August 2020

The psychologist's job within basic education schools is increasingly requested, however, it is important to think about what is expected of that role. Managers, administrators, teachers, students and parents have different imaginaries about what a psychologist is, and making them converge might seem like an impossible task. The clinical listening, the intervention and the clinical look can be generators of a large number of structural and subjective movements within basic education context; these allow the infant to resist the transition in that period of his formation. Therefore the objective of this article was to think about the clinical psychologist’s practice in basic education, from a direct type experience.

The technological advance has given greater growth towards the new digital platforms that facilitate or allow accessibility to assets. The following research work aims to analyze the scope of the regulation of the virtual asset market in Mexico. The methodology used for this research was the qualitative, which consists of reviewing international and national sources of studies in this area and analyzing the scope of the Fintech Law on the regulation of said assets. The investment in cryptocurrencies and their operation are very important for people, but they have their negative side for the global economy and can affect financial systems due to the inherent risks of the market. Once analyzed from different perspectives, it´s concluded that Mexico is a reference in Latin America in the regulation of said market, however, the Bank of Mexico does not recognize this type of assets as legal tender and that they lack the characteristics of value deposit, medium of exchange and unit of account. In addition, the law only regulates the internal operations of financial technology companies and does not support the operations carried out by the general public.

Nesta pesquisa, propomos-nos a analisar duas dimensões, o perfil profissional dos professores dos cursos de engenharia com menos de cinco anos de atuação, e os fios condutores das suas práticas pedagógicas em duas Instituições de Ensino Superior de Santa Catarina. O aporte teórico foi baseado em alguns autores como Huberman (1992); Nóvoa (1995) e Tardif (2008), para compreensão dos processos constitutivos e das fontes sociais de aquisição da formação docente. A presente pesquisa tem caráter qualitativo e realizou-se por meio de aplicação de questionário on-line com perguntas abertas, de múltiplas escolhas e questões seguindo uma escala de resposta do tipo Likert. Para a interpretação e análise das informações obtidas, aplicou-se a metodologia de Análise de Conteúdo, organizando os dados em categorias, as quais nos possibilitaram um mapeamento do perfil dos professores iniciantes que atuam nos cursos de engenharias, assim como os elementos que fortalecem e dificultam a docência e as principais práticas pedagógicas. As análises decorridas a partir dos dados obtidos reforçam os apontamentos contidos na literatura sobre a fragilidade da profissionalidade docente e dificuldades encontradas na trajetória nos primeiros anos de docência. Desse modo, o presente estudo nos proporcionou compreender os desafios presentes nas universidades, no que tange à complexidade e à singularidade em ser professor iniciante.

Este artigo objetivou analisar a relação trabalho e educação profissional do campo, na perspectiva de compreender de que forma a formação técnico-profissional do Instituto Federal do Pará – Campus Marabá Rural tem contribuído com a Educação do Campo. Toma-se como referência o curso técnico em agropecuária integrado ao ensino médio ofertado em parceria com o movimento social e sindical através do Programa Nacional de Educação na Reforma Agrária (PRONERA) no período de 2009 a 2013. Parte desta abordagem integra a pesquisa de mestrado profissional, cuja metodologia referenciou-se no materialismo histórico-dialético, incluindo também a pesquisa bibliográfica e documental, como procedimento. Os resultados da investigação apontaram o comprometimento da formação, materializado sob a perspectiva da Educação do Campo, com o projeto de desenvolvimento da agricultura familiar camponesa na região. A pesquisa apontou ainda uma nova de forma de produzir conhecimento, fundamentando a escola do campo na construção da nova matriz produtiva camponesa, colocando a concepção de educação profissional no plano da formação humana e não apenas da instrução.

Este texto aborda uma das dimensões exploradas em recente pesquisa de doutorado sobre as desigualdades de oportunidades educacionais como um fenômeno que se evidenciou no estudo do perfil social e acadêmico dos estudantes da UFMG, contemplados pelo programa de mobilidade internacional “Ciência sem Fronteiras”, criado em 2011, pelo governo federal. A despeito do principal objeto dessa pesquisa, os dados obtidos revelaram diversas expectativas dos entrevistados a respeito dos possíveis impactos desse intercâmbio em sua formação profissional e carreira. Portanto, esse trabalho tem o propósito de demonstrar as diferentes motivações subjacentes à opção pelo intercâmbio, relacionadas a esse factível impacto. A referência metodológica para essa questão de pesquisa baseou-se na análise de conteúdo, por meio do estabelecimento de categorias que orientaram o estudo qualitativo do discurso dos entrevistados. Constituíram-se como principais categorias de análise motivadoras do intercâmbio para fins profissionais e de carreira: a influência familiar, a opção pelo país e a universidade de destino, o estabelecimento de networkings (capital social), a aprendizagem de língua estrangeira para o aprimoramento profissional, o contato com diferentes culturas e ainda a possibilidade da pós-graduação, tendo em vista a especialização para a carreira de pesquisa e docência universitária. A conclusão é a de que o intercâmbio é uma oportunidade ímpar que se estende para além dos benefícios pedagógicos e culturais previstos.

A pandemia por SARS-CoV-2 traz graves consequências para o aparelho respiratório que se agrava quando há concomitante envolvimento cardíaco, o que não raramente ocorre, principalmente em pacientes internados. As alterações cardíacas são caracterizadas por reações inflamatórias sistêmicas, hipóxia generalizada, tromboses de coronárias epicárdicas ou de pequenos vasos, infecção viral do miocárdio, ou hipertensão pulmonar aguda como resultado do embolismo pulmonar ou trombose local. A lesão miocárdica medida pela elevação de troponina é ominosa. Achados de imagem, principalmente ecocardiograma à beira do leito, assim como a cineangiocoronariografia e a ressonância magnética cardíaca têm sido de grande utilidade para o reconhecimento da lesão. Assim como, arritmias, infarto do miocárdio, insuficiência cardíaca e choque são manifestações principais de envolvimento cardíaco. Nos casos leves a moderados, as medicações prévias, principalmente os inibidores da enzima de conversão da angiotensina (IECA), bloqueadores de receptores de angiotensina (BRA), estatinas e outros correlatos devem ser mantidos. Nos casos graves a atenção se volta para o uso de drogas vasoativas potentes. Uma atenção especial se volta para os cuidados de pacientes que precisam de atendimento pelas manifestações cardiológicas, principalmente o infarto agudo do miocárdio e a insuficiência cardíaca, nesse momento de receio de contaminação hospitalar. Os Serviços têm providenciado ao máximo as medidas de proteção com fluxo distinto para esses pacientes. Após a COVID-19, o retorno às atividades mais exigentes deve ser precedido de cuidadosa avaliação médica para orientações sobre possíveis sequelas.

A pandemia da COVID-19 trouxe um grande desafio para a equipe de unidade de terapia intensiva. Inicialmente pela grande quantidade de afluxo de pacientes, a falta de suprimentos gerou quadros mais severos de síndromes respiratórias agudas (SARS e outras) e mais longos nas unidades, em seguida os protocolos de não se por em risco a equipe laborativa e a falta de profissional qualificado para determinadas condições geradas pela doença, como a lesão renal aguda (LRA), criou um cenário estressante e desafiador para equipes médicas, para o doente e a família. Além disso, a falta de um conhecimento prévio sobre a doença colocou os médicos em posição de decisões para as quais ainda não havia literatura consubstanciada. Neste artigo tratamos desses desafios e das condutas relacionadas à necessidades geradas pela COVID-19 em UTIs principalmente no que concerne à ventilação mecânica.
