SEEDLING PRODUCTION CATTLEYA ELDORADO IN SUBSTRATES WITH NUTRITIVE SOLUTION UNDER SHADING SCREENS

Further researches are necessary to better understand the various technical and physiological aspects entailed by the use of substrates, shading and mineral fertilization resulting otimization in their application in the production of Cattleya eldoradoseedlings. The study was conducted with the aim of verify the effect of shading screens in the initial growth of Cattleya eldoradoseedlings in substrates fertilized with nutritive  solution. The experimental design was completely randomized 2x3x2 factorial with four replications. The studied factors: (T1)= crushed cupuaçupeel (sub1); (T2)= industrialized coconut fiber (sub2); (T3)= blend 50% sub1 + 50% sub2 with and without nutritive solution under red or black cromatinet. The analyzed variables were: aerial part height, number of leaves and chlorophyll a and b throught 300 days. Fertilization with nutritive solution promotes height growth and number of leaves results in higher levels of chlorophyll a and b, under red as black cromatinet, indicated for seedlings growth.Pesquisas adicionais são necessárias para se entender melhor os vários aspectos técnicos e fisiológicos acarretados pelo uso de substratos, sombreamento e fertilização mineral, a fim de otimizar sua aplicação na produção de mudas de C. eldorado. Diante do exposto, o trabalho foi realizado com objetivo de verificar o efeito de telas de sombreamento no crescimento inicial de mudas de C. eldoradoem substratos fertilizados com adição de solução nutritiva. O delineamento experimental utilizado foi o inteiramente casualizado em esquema fatorial 2x3x2 com quatro repetições. Os fatores em estudo foram: (T1)= casca de frutos de cupuaçu triturada (sub1); (T2)= fibra de coco industrializada (sub 2); (T3)= 50% mistura de sub1 + 50% mistura de sub2 com e sem adição de solução nutritiva sob cromatinet vermelha e cromatinet preta. As variáveis avaliadas foram: a altura da parte aérea, número de folhas e clorofila a e b, ao longo de 300 dias após o transplantio. A fertilização com adição de solução nutritiva favorece o crescimento em altura e o número de folhas e resulta em maiores índices de clorofila a e b tanto em cromatinet vermelha quanto preta, sendo indicada para crescimento de mudas de C. eldorado

Factors Associated with Emotion Regulation in Men with Internet Access Living in Brazil during the COVID-19 Pandemic

Publisher Copyright: © 2022 by the authors. Licensee MDPI, Basel, Switzerland.Objective: to evaluate the factors associated with emotion regulation in men with internet access living in Brazil during the COVID-19 pandemic. Method: an epidemiological survey, conducted with 1015 men. An electronic form was applied containing sociodemographic and occu-pational characteristics, support and coping strategies, as well as emotional and behavioral aspects. Emotion regulation was assessed using the Emotion Regulation Questionnaire. Results: The prevalence values observed were 44.6% for Low Cognitive Reappraisal and of 47.1% for High Emotional Sup-pression. The following factors were identified as associated: (a) with Low Cognitive Reappraisal: being aged 30 years old or more, practicing physical activity, worrying about social distancing and having positive emotions and feelings; and (b) with High Emotional Suppression: being heterosexual, non-white race/skin color, having security support or public administration, not sanitizing food, worrying about lack of physical activity and not having negative emotions. Conclusion: the adoption of emotion regulation strategies was associated with individual, contextual and emotional/behavioral characteristics. Masculinity ideals seem to exert an influence on these relationships.publishersversionpublishe

Men’s feelings and emotions in the covid-19 framing

O objetivo deste artigo é compreender como os sentimentos e as emoções de homens contribuem para o enquadramento da doença Covid-19 no Brasil. Estudo sócio-histórico, qualitativo, realizado com 200 homens residentes no Brasil, mediante pesquisa online em plataforma digital. Os dados apreendidos foram analisados pelo método do Discurso do Sujeito Coletivo à luz do referencial de doença epidêmica proposto por Charles Rosemberg. Prevaleceram sentimentos negativos e ansiedade como consequência do conhecimento acerca do crescente número de hospitalizados e mortos pela pandemia veiculada nos noticiários. Para os homens, o otimismo é necessário para encorajar atitudes com responsabilidade e confiar de que a crise será superada. Na sequência os homens apresentam um conjunto de atitudes e comportamentos para o enfrentamento da pandemia. E, a aceitação sinaliza a emergência do quarto ato dramatúrgico do enquadramento da Covid-19. Os sentimentos e as emoções de homens, no presente contexto histórico, atravessam três dos quatro atos de enquadramento da Covid-19 no Brasil. Objective to understand how men’s feelings and emotions contribute to the Covid-19 framing in Brazil. Method: Asocial-historical, qualitative study, carried out with 200 men resident in Brazil, through online search on digital platform.The grasped data were analyzed by the Collective Subject Discourse method in the light of the reference of epidemic disease proposed by Charles Rosemberg. Results: Negative feelings and anxiety prevailed due to the knowledge about the growing number of hospitalized patients and deaths from the pandemic conveyed in the news. For men, the optimism is necessary to encourage attitudes with responsibility and trust that the crisis will be overcome.Subsequently, men present a set of attitudes and behaviors for coping with the pandemic.Moreover,the acceptance signals the emergence of the fourth dramaturgical act of the Covid-19framing. Conclusion: Men’s feelings and emotions, in this historic context, pervade three of the four acts of the Covid-19 framingin Brazil.publishersversionpublishe

Measurement of the cosmic ray spectrum above 4×10184{\times}10^{18} eV using inclined events detected with the Pierre Auger Observatory

A measurement of the cosmic-ray spectrum for energies exceeding $4{\times}10^{18}$ eV is presented, which is based on the analysis of showers with zenith angles greater than $60^{\circ}$ detected with the Pierre Auger Observatory between 1 January 2004 and 31 December 2013. The measured spectrum confirms a flux suppression at the highest energies. Above $5.3{\times}10^{18}$ eV, the "ankle", the flux can be described by a power law $E^{-\gamma}$ with index $\gamma=2.70 \pm 0.02 \,\text{(stat)} \pm 0.1\,\text{(sys)}$ followed by a smooth suppression region. For the energy ($E_\text{s}$) at which the spectral flux has fallen to one-half of its extrapolated value in the absence of suppression, we find $E_\text{s}=(5.12\pm0.25\,\text{(stat)}^{+1.0}_{-1.2}\,\text{(sys)}){\times}10^{19}$ eV.Comment: Replaced with published version.

Energy Estimation of Cosmic Rays with the Engineering Radio Array of the Pierre Auger Observatory

The Auger Engineering Radio Array (AERA) is part of the Pierre Auger Observatory and is used to detect the radio emission of cosmic-ray air showers. These observations are compared to the data of the surface detector stations of the Observatory, which provide well-calibrated information on the cosmic-ray energies and arrival directions. The response of the radio stations in the 30 to 80 MHz regime has been thoroughly calibrated to enable the reconstruction of the incoming electric field. For the latter, the energy deposit per area is determined from the radio pulses at each observer position and is interpolated using a two-dimensional function that takes into account signal asymmetries due to interference between the geomagnetic and charge-excess emission components. The spatial integral over the signal distribution gives a direct measurement of the energy transferred from the primary cosmic ray into radio emission in the AERA frequency range. We measure 15.8 MeV of radiation energy for a 1 EeV air shower arriving perpendicularly to the geomagnetic field. This radiation energy -- corrected for geometrical effects -- is used as a cosmic-ray energy estimator. Performing an absolute energy calibration against the surface-detector information, we observe that this radio-energy estimator scales quadratically with the cosmic-ray energy as expected for coherent emission. We find an energy resolution of the radio reconstruction of 22% for the data set and 17% for a high-quality subset containing only events with at least five radio stations with signal.Comment: Replaced with published version.
