Authors: Gómez-Rodríguez Dustin Tahisin
Published: December 2021

El objetivo general del artículo fue analizar las tendencias globales en las que se desenvuelve la agroindustria, así como mostrar algunos instrumentos que se pueden utilizar para medir la sostenibilidad tanto fuerte como débil en aras del desarrollo sostenible como eje trasversal de Agenda 2030 como los Objetivos de Desarrollo del Milenio. La metodología fue de corte cualitativo y el método fue de revisión documental. La conclusión principal, es que la agroindustria a medida que pasa el tiempo tiene mayor relevancia en el desarrollo de las sociedades dado su relación directa con la obtención de calorías por parte de los animales humanos y no humanos. Acotando que las tres tendencias en las que se desenvuelve son la Bioeconomía, la Biotecnología y la Agroindustria 4.0.
Dynamics of Suffering of Female Brazilian Psychology Students: Interfaces with the COVID-19 Pandemic
Authors: Sobral Maria Eduarda Carvalho
Published: December 2021

The asymmetric construction of gender roles in the Brazilian society contributes to the fact that, currently, women's experiences in the university environment are marked by gender bias. This situation was aggravated by the pandemic. The present research aimed to evaluate the dynamics of pleasure and suffering in the academic work of undergraduate psychology students at the University of Brasília, Brazil, as well as to identify the main strategies used by them to face it. The theoretical-methodological perspective adopted was the psychodynamics of work and female work. The research is characterized as descriptive, quantitative and qualitative. The Work-Related Injury Scale was applied to 196 female students and eight focus groups were held, with an average of 4 (four) participants each. As a result, in the quantitative stage, it was found that, in the three factors of the scale, a median result was obtained, which means a state of alert regarding the harm and psychosocial risks related to work. In the qualitative stage, six categories were identified: "Being a woman and being a student", "Intersections of suffering", "Impact of the pandemic at work", "Collective mediation strategies", "Individual mediation strategies" and "Socio-professional relationships". The results are discussed considering that women still have to deal with the triple workload overload, and that they do not feel safe to freely occupy the university environment, implying the need to promote more institutional listening and welcoming spaces, so that it is possible to build strategies to transform the organization of work. Shortterm actions are recommended so that the alert state in relation to risks at work is not aggravated.
Death Avoidance Behavior of Accidentally Injured Cub in Platyrrhini: An Opportunistic Observation Record
Authors: Nogueira de S Romes Bittencourt
Published: December 2021

Introduction: Infraorder Platyrrhini is composed of species with complex social structures, but information about their interaction with death is scarce in the literature, as already registered for old world monkeys. This work concern of death avoidance behavior recorded in a group of Callithrix penicillata (E. Geoffroy, 1812) (Primates, Callitrichidae). Material and Methods: This is a study made it through opportunistic observation of an interaction between a mother and her cub, accidentally injured and on the deathbed. The detailed description of the phenomenon occurred through all occurrence sampling, and was counted on the testimony of local residents. For better data exposure, an etogram was constructed, containing all the observed behaviors, in sequence, from the beginning to the end of the sampling. Results: In all, 10 individuals participated in the observations, and 16 behavioral acts were observed during 6 days of observation of the interaction mother-child injured-other individuals. The behaviors indicated a high degree of stress on the part of all involved, as well as the mother's attempt to withdraw her cub from the area in which was. The mother also tried to bring it to your back. There were other individuals in the group, possibly to assist in caring for the cub. 1 Conclusion: This work is unpublished for the specie in question and reaffirms its social character. The observations open spaces for further investigation into similar behaviors in human and non-human primates as well as the phylogenetic relationship between them.
Testicular Cancer - An Unexpected Course of the Disease
Authors: Gamulin Marija
Published: December 2021

There are two major histologic types of testicular cancer: pure seminoma and nonseminomatous germ cell tumours which include embryonic carcinoma, choriocarcinoma, yolc sac tumours and teratomas. Rarely, in 2% of cases, teratomas may contain elements of somatic cancer, such as sarcoma or adenocarcinoma and it is then referred to as a ''teratoma with somatic type malignancy''. The histology of somatic malignant elements most commonly includes adenocarcinoma and various types of sarcomas; however, so far as the primitive neuroectodermal tumors (PNETs) are concerned the experience is quite limited. Here we report an unusual case of a testicular seminoma that relapsed 6 months after surgery as a teratoma with somatic neuroendocrine differentiation situated in retroperitoneal lymph nodes.

La legalidad de los actos relativos a los métodos especiales de investigación criminal
Authors: Bravo-Tuárez Temístocles Lastenio
Published: December 2021

Los delitos no convencionales, también llamados delitos de cuello blanco y la criminalidad organizada, son un tema recurrente en las sociedades modernas que transgrede las barreras territoriales y requiere de métodos especiales de investigación criminal con el fin de buscar material probatorio. Así mismo, los métodos especiales de investigación criminal, como formas o mecanismos de enfrentar hechos de esta naturaleza, con una significativa complejidad, tanto en la ejecución y los medios utilizados, formas de participación, estructuras y organización delincuencial. Temas que para Cuba se vuelven complejos, en tanto solo se regulan en normativas institucionales y no en las leyes penales sustantivas o adjetivas.

The Progress of Regulation and Implementation of E-Democracy in Colombia
Authors: Silva-Arroyave Sergio Orlando
Published: December 2021

Para identificar los avances del gobierno colombiano en la regulación de la democracia electrónica y mejorar su implementación es necesario aclarar el concepto de gobierno electrónico y distinguirlo de la democracia electrónica. Esto se debe a que el uso actual del gobierno electrónico excede sus límites teóricos y dogmáticos y entra en el significado de democracia electrónica. Esta confusión se da en Colombia desde el diseño de la primera política de “Gobierno en línea", que perseguía “la construcción de un gobierno más eficiente, transparente y participativo y la oferta de mejores servicios a los ciudadanos y empresas, a través del uso de la Información y la Comunicación Tecnologías”. Por lo tanto, esta confusión debe ser aclarada, porque de lo contrario se corre el riesgo de creer erróneamente que todos los avances que se realicen en el área del gobierno electrónico necesariamente tienen como objetivo generar avances hacia la democracia electrónica. Este artículo de investigación, siguiendo un método analítico-descriptivo, busca identificar si el uso de las TIC por parte del gobierno colombiano realmente ha mejorado la calidad de su democracia y reconocer las acciones que debe tomar para implementar eficientemente la regulación de la democracia electrónica.
Entre la nueva ruralidad y la nueva educación: Hacia un contexto reflexivo desde un enfoque pedagógico crítico
Authors: Montoya-Soto David , Muñoz-Gaviria Diego Alejandro
Published: December 2021

El presente trabajo se inscribe en la corriente de pensamiento crítico, que desde Karl Marx hasta Paulo Freire centra su interés académico y político en la emancipación humana. Por ello, el siguiente escrito se dirige a la comprensión de la pedagogía y la educación en clave crítica en especial en un contexto rural. En donde se hacen necesarias nuevas prácticas emancipatorias. Es así como para la tradición crítica el conocimiento sólo se legitima en tanto práctica de la libertad, es decir, en tanto praxis transformadora de realidades opresoras. Construir conocimiento crítico, teoría crítica y no tradicional como lo apunta (Horkheimer, 2003), es asumir el reto de cambiar las formas de vida en la intención de propiciar en todos los espacios, tiempos y prácticas que intensifiquen en el ser humano la conquista de su libertad, emancipación o autonomía.

Recensie: prentenboek ‘Spiedie’, epilepsievoorlichting voor jonge kinderen
Authors: Van de Corput John
Published: December 2021

Een epilepsieaanval kan veel impact hebben, zeker als het een tonisch-clonische of complex partiële aanval betreft. In mijn contacten met kinderen en jongeren met epilepsie,hun ouders en scholen blijkt dat onbekendheid met epilepsie en het feit dat aanvallen onverwacht gebeuren er mede de oorzaak van zijn dat men van een aanval schrikt. Goede epilepsievoorlichting aan leerkrachten en klasgenoten is daarom van belang. Op die manier kan epilepsie beter worden herkend en kan er meer begrip komen voor de aanvallen.
Performance of Different Clones of Morus alba for Morphometric Traits in a Clonal Evaluation Trial
Authors: Thakur I.
Published: December 2021

Variation among different traits along with their correlation were studied in twenty seven clones of Morus alba . The significant differences were found among clones with respect to various morphometric traits. Moderate phenotypic coefficient of variation (PCV), genotypic coefficient of variation (GCV), heritability and genetic gain were recorded for green leaf yield, ramet height, leaf length, leaf width and basal diameter indicating that these characters can be more reliable for effective selection in future. Ramet height showed positive and significant correlation with basal diameter (0.5287), leaf length (0.4671), number of branches (0.6043), and green leaf yield (0.6893). Basal diameter, leaf length and leaf width also exhibited positive and significant correlation with green leaf yield i.e. 0.4705, 0.5714, 0.4813, respectively. Hence, these correlations can be useful in the indirect selection of the species.

Authors: KHOSRAVI YOUNES , LASHKARI HASAN , ASAKEREH HOSEIN
Published: December 2021

In this study two regression models, ordinary least square and geographically weighted regression as widely applied techniques, were used in modeling the regression relationships between water vapour and related geographic features, i.e., longitude, latitude, elevation, slope and aspect. Accordingly, the water vapour data in south and southwest of Iran were collected in pixels in the time interval 1981-2010. According to the general OLS regression, the relationship between WV and latitude, elevation and aspect were reverse and with longitude and slope were positive. Analyzing the relationship between geographic features and WV by GWR model determined that greatest coefficients of explanatory variables were in longitude, latitude, slope, aspect and elevation, respectively. Regarding to the model performance, GWR showed an improvement over OLS in estimating the WV and provided more realistic and useful results. So that the R2, Adjusted R2 and AICc for GWR were 0.967, 0.968 and 9329.38, respectively while these factors for OLS were 0.8478, 0.8475 and 14559.04.

Published: December 2021

Extreme rainfall events are a significant cause of loss of life and livelihoods in Odisha. Objectives of the present study are to determine the trend of the extreme rainfall events during 1991-2014 and to compare the events between two periods before and after 1991. Block level daily rainfall data were used in identifying the extreme rainfall events, while district level aggregation was used in analysing the trend   in three categories, viz., heavy, very heavy and extremely heavy rainfall as per criteria given by India Meteorological Department (IMD). The state as a whole received one extremely heavy, nine very heavy, and forty heavy rainfall events in a year. When percentage of occurrence of each category out of the total extreme events over different districts was considered, maximum % of extremely heavy rainfall occurred in Kalahandi (5.8%), very heavy rainfall in Bolangir (23.8%) and heavy rainfall in Keonjhargarh (85.4%). Trend analysis showed that number of extreme rainfall events increased in a few districts, namely, Bolangir, Nuapada, Keonjhargarh, Koraput, Malkangiri, and Nawarangapur and did not change in other districts. In Puri district, extremely heavy rainfall frequency decreased. New all-time record high one-day rainfall events were observed in twenty districts during 1992 to 2014, surpassing the earlier records, which could be attributed to  climate change induced by  global warming. Interior south Odisha was found as the hot spot for extreme rainfalls.
Understanding the uncertainty cascaded in climate change projections for agricultural decision making
Authors: RAMARAJ A. P. , GEETHALAKSHMI V. , BHUVANESWARI K.
Published: December 2021

Climate projections have confirmed the need to adapt to a changing climate, but have been less beneficial in guiding how to effectively adapt. The reason is the uncertainty cascade, from assumptions about future emissions of greenhouse gases to what that means for the climate to real decisions on a local scale. Each of the steps in the process contains uncertainty and these uncertainties from various levels of the assessment accumulate. This cascade of uncertainty should be critically analyzed to inform decision makers about the certain range of future changes. Most widely used approaches like Bayesian and Monte Carlo gives specific values of parameters and their confidence, yet for agricultural decision making the range of possible changes itself is required as such to understand impact at every point of these ranges. This paper addresses these issues and examines the uncertainties in climate projections at a local scale. In the study locations (Coimbatore and Thanjavur), irrespective of the models, scenarios and time slices, the maximum and minimum temperatures are projected to increase with seasonal variations. With certainty, the projected increase in maximum and minimum temperature over Coimbatore is 0.2 to 4.1 ºC and 0.3 to 5.3 ºC and over Thanjavur is 0.3 to             4.6 ºC and 0.2 to 5.2 ºC, respectively. Rainfall is projected to vary between a decrease of 15.0 to an increase of 73.1 percent for Coimbatore and a decrease of 15.3 to an increase of 80.7 per cent for Thanjavur during the 21st century. On comparing the monsoon seasons, southwest monsoon (SWM) is projected to have a higher increase in both maximum and minimum temperature than northeast monsoon (NEM) for both the study locations, similar to their current trends. Rainfall is projected to increase more in NEM than in SWM.
A statistical analysis of the differences between rainfall estimated by Chennai DWR and conventional rainfall data on monthly and seasonal scales during the Indian northeast monsoon season
Authors: AMUDHA B. , RAJ Y. E. A. , THAMPI S. B.
Published: December 2021

The first Doppler Weather Radar (DWR) of India Meteorological Department has been functional at Chennai since the year 2002 providing various meteorological and hydrological products. Validation and statistical analysis  of  the DWR estimated rainfall (RERF, x) data with rain gauge measured rainfall (RGRF, y) of 34 land based stations located in the semi-circular land area within 100 km radius of  Chennai DWR (CDLR100) has been performed for  the northeast monsoon (NEM) season of October-November-December (OND)  for the  12 year period 2002-13. The monthly and seasonal data have been derived using more than 1.42 lakh discrete daily RERF values available at a high resolution of 333 m × 333 m.
         The major objective of the study is to compute the various statistical parameters of x and y including the bias between them on monthly and seasonal scales and to draw certain inferences. The analysis was done using three different types of averaging.  The yearly means  of  x and  y for OND over CDLR100 manifested both positive and negative epochs with the mean absolute deviation (MAD) computed as 11 cm (17% of mean). The short term normals over CDLR100 are derived as 274.9, 262.6, 96.5 and 629.8 mm for x and 243.8, 254.6, 128.0 and 627.4 mm for y for October, November, December and OND yielding bias values of -31.2, -8.0, 31.5 and -2.4 mm respectively.  The MAD for OND rainfall computed by pooling in all the 12 ´ 34 values is quite substantial at around 19 cm (30% of mean). The RF bias for each month / NEM season is shown to be independent of the geographical locations of the stations using correlation analysis.  Based on the raw values of  x and a proportional correction technique, estimated values of at the 1.42 lakh grid points  of  CDLR100  were derived yielding spatial means  of  273.3, 262.2, 92.5 and 628.4 mm for  x  and 243.4, 254.3, 122.9 and  622.1 mm  for   for the three months and OND respectively. The importance of size  of  the bias in the correct interpretation  of  x  has been discussed.  A few suggestions  based  on certain  statistical considerations have been putforth for decreasing the bias.
Role of weather factors in development of late leaf spot (Phaeoisariopsis personata) on groundnut (Arachis hypogaea)
Authors: DEY UTPAL , DHUTRAJ D. N. , TALUKDAR DIGANGGANA , DAS ANUP
Published: December 2021

The field experiment was conducted during Kharif 2012 and 2013 to find out the influence of weather parameters viz., temperature, relative humidity, rainfall, rainy days and wind velocity on the intensity of late leaf spot disease and defoliation in four groundnut cultivars viz., JL-24, LGN-1, TAG-24 and TG-26. The prevailing weather condition viz., average temperatures of 30.92 °C (max.) and 22.31 °C (min.), average RH of 89.67 % (morning) and 64.25 % (evening), well distributed average rainfall of 50.33 mm, average rainy days of 2.67 and average wind velocity of 4.24 km/hr were found to be conducive for the initiation, development and spread of late leaf spot disease in susceptible groundnut Cv. JL-24, TAG-24 and tolerant Cv. LGN-1, TG-26. As a result, overall average maximum disease intensity of 33.97 (21.96 to 46.37 %) per cent and 29.06 (18.62 to 39.01 %) per cent, were recorded in JL-24 and TAG-24, respectively. Groundnut Cv. JL-24 and TAG-24 (susceptible) exhibited comparatively maximum average defoliation in the range of 6.65 to 14.05 (Av. 10.29 %) and 5.64 to 11.82 per cent (Av. 8.80 %), respectively. The correlation coefficient between weather variables and disease intensity in both the years indicated that maximum temperature had negative and non significant effect in all the groundnut cultivars; whereas, minimum temperature had positive and significant effect on the disease intensity in all the groundnut cultivars. Relative humidity (morning and evening) played significant positive role on the disease intensity in all the groundnut cultivars.
Modelling long memory in maximum and minimum temperature series in India
Authors: PAUL RANJIT KUMAR
Published: December 2021

Time series analysis of weather data can be a very valuable tool to investigate its variability pattern and, maybe, even to predict short- and long-term changes in the time series. In this study, the long memory behaviour of monthly minimum and maximum temperature of India for the period 1901 to 2007 by means of fractional integration techniques has been investigated. The results show that the time series can be specified in terms of autoregressive fractionally integrated moving average (ARFIMA) process. Both the series were found to be integrated with orders of integration smaller than 0.5 ensuring the long memory stationarity. Wavelet methodology in frequency domain with Haar wavelet filter was applied in order to see the oscillation at different scale and at different time epochs of the series. Multiresolution analysis (MRA) was carried out to explore the local as well as global variations in both the temperature series over the years. The variability in minimum temperature is found to be more than maximum temperature. Though there is no clear significance trend in the temperature series in the long run, but there are pockets of change in the temperature pattern. The predictive ability of ARFIMA model was investigated in terms of relative mean absolute percentage error.
Brinquedos no museu: ensinamentos e sentimentos nos usos da cultura material
Authors: Becker Morales Martha Helena
Published: December 2021

Este artigo apresenta os resultados de uma pesquisa realizada em torno de um conjunto de brinquedos doados ao Museu Paranaense entre 2014 e 2015. Três ênfases recaem sobre a análise da cultura material: em primeiro lugar, a agência das doadoras que, antes de repassá-los à instituição, classifica e seleciona os objetos conforme suas expectativas de consolidação da memória. Em segundo lugar, o museu e a transformação de experiências particulares em um discurso representativo de coletividades. Por fim, há o destaque às muitas possibilidades interpretativas que o novo acervo musealizado permite, direcionando olhares de pesquisador e visitante – duas categorias presentes no cotidiano do museu. Em termos práticos, o artigo problematiza os brinquedos em questão como pedagogias culturais materiais que agem na intersecção do consumo pretendido no início do século XX com o potencial explicativo no contexto museológico do início do século XXI. Assim, diferentes ensinamentos, sentimentos e usos são abordados para delinear práticas de poder e construção de papéis específicos a serem viabilizados pela cultura material.
Retratos escolares: representações e artefatos da cultura escolar – Foto Bianchi, Ponta Grossa-PR (1936-1938)
Authors: Barbosa Audrey Franciny
Published: December 2021

O presente artigo analisou de que forma o espaço e as relações escolares foram representadas nos retratos escolares produzidos pelo estúdio fotográfico Foto Bianchi (1913-2001), em Ponta Grossa-PR, durante sua primeira geração de fotógrafos – período correspondente aos anos entre 1913-1943. Para este momento, o que se propôs foi refletir de que forma os retratos escolares analisados pela pesquisa se apresentam enquanto artefatos da cultura material escolar, cujas representações fotográficas desempenharam funções simbólicas e materiais. Para isso, a análise se deteve nos retratos de normalistas produzidos pelo fotógrafo no espaço interno do estúdio entre os anos de 1936-1938, um pequeno corpo documental, composto por dez retratos, que suscitou a problemática acerca das poses, técnicas, usos, consumo e circulação desses retratos. Diante disso, o trabalho encontrou respaldo teórico nas discussões da História Cultural articulada à Cultura Visual e à História da Educação, uma vez que compreendeu os retratos fotográficos como representações e artefatos visuais que nos dão indícios sociais/culturais de seu contexto de produção e dos sentidos na escola no período. Por fim, a metodologia empregada consistiu na iconografia/iconologia revisada (KOSSOY 2009, 2014) em diálogo com as formas de expressão e conteúdo (MAUAD, 1996), tendo em mente as discussões acerca do circuito social da fotografia (MAUAD, 1996).

In the present work a comparison of the three model distribution of DM (NFW, Moore and Burkert) with varying degrees of singularity in the center, or without it, is carried out for four low surface brightness galaxies. Contrary to the claims in the literature, the results of fitting the observed rotation curves do not allow one to speak of the unique preference for any one of the models. For two of the four galaxies the highest levels of significance has the NFW model, and for the other two – the Burkert model. Simulation is carried out also taking into account the criteria of marginal gravitational stability of galactic disks. A comparison with the photometric data shows that the disks of galaxies under consideration, are perhaps overheated, because modeling without this criterion gives better agreement with the photometric data and better values of the chi-square test for rotation curves

Published: December 2021

This work continues the research on modeling of passive methods of management of flow regimes in the boundary layers of compressed gas. Authors consider the influence of pressure gradient on the evolution of perturbations of different nature. For low Mach number M = 2 increase in pressure contributes to an earlier transition of laminar to turbulent flow, and, on the contrary, drop in the pressure leads to a prolongation of the transition to turbulence. For high Mach number M = 5.35 found that the acoustic disturbances exhibit a very high dependence on the sign and magnitude of the external gradient, with a favorable gradient of the critical Reynolds number becomes smaller than the vortex disturbances, and at worst – boundary layer is destabilized directly on the leading edge

Experimental studies of the hydrogen combustion in the round and plane microjet in cross acoustic field at low Reynolds numbers are presented. The results are compared with the results obtained during the combustion of propane, studied earlier in the same experimental conditions. It is shown that the lifted flame of propane at diffusion combustion in a round microjet, under the influence of a transverse acoustic field, subject to bifurcation. This phenomenon is associated with the development of a sinusoidal oscillation process occurring under the influence of a transverse acoustic field. For the case of hydrogen combustion of plane microjet to lift the flame also failed, but the bifurcation effect is manifested at velocity close to 450 m/s. In this case acoustic disturbances generated by the jet, and a sinusoidal instability is typical for the plane jets
