Batman e Coringa: complexidades da dinâmica relacional expressa nos quadrinhos

Os quadrinhos causam reações estéticas e processos de identificação que permitem acessar conflitos e compreender aspectos subjetivos. Este artigo busca analisar a dinâmica relacional entre os personagens principais dos quadrinhos da série Batman. Para tal, foi empregado o Método Objetivo Analítico sobre o quadrinho Batman: A Piada Mortal. Individualmente, as histórias dos personagens são marcadas por perdas e ambientes ausentes de um cuidado necessário à afetividade. Este contexto leva-os a manter uma relação de agressividade calcada na dependência e na busca de reparação das perdas. Conclui-se que os quadrinhos permitem observar sutilezas da experiência humana de relevância clínica, apresentando um interessante potencial pedagógico.Comics cause aesthetic reactions and identification processes that allow addressing conflicts and understanding subjective aspects. This article aims to analyze the relational dynamics between the main characters of the Batman comic series. To do so, the Objective Analytical Method was used for the comic book Batman: The Killing Joke. Individually, the characters’ stories are affected by losses and environments deprived of a care necessary for affection. This context leads them to sustain an aggressive relationship based on mutual dependence and on the search for repairing their losses. It is concluded that comics shed light on clinically relevant subtleties of the human experience, presenting an interesting pedagogical potential

Morphogenic Responses of Two \u3cem\u3eBrachiaria\u3c/em\u3e Genotypes in Response to Clipping Frequency

Tropical grasslands represent an important resource for the Brazilian cattle industry, which is heavily dependent on grazed pastures. Total pasture area in the country totals 196 M ha (23% of the country’s land area) (FAO 2013). The genus Brachiaria represents around 85% of cultivated pastures in Brazil (Moreira et al. 2009), 40% of which are established with B. brizantha cv. Marandu (Barbosa 2006). Mulato II is a new hybrid brachiaria grass cultivar which has been developed to improve agronomic characteristics, broaden the range of adaptation, and to ensure high forage production and nutritive value. It has also been viewed as a means of reducing the dependence on the Marandu palisade grass monoculture (Argel et al. 2007). The use of new cultivars should be based on adequate understanding of physiological processes and growth potential under a range of management practices. Morphogenic characteristics allow for accessing herbage accumulation potential through the measurement of tissue synthesis and senescence in forage plants. Management practices such as defoliation frequency can modify assimilate partitioning in the forage plant, affecting morphogenic characteristics related to growth rate and forage nutritive value. The objective of this research was to describe and explain morphogenic differences between Marandu palisade grass and Mulato II brachiaria grass as affected by harvest frequency

Climate impact and adaptation to heat and drought stress of regional and global wheat production

Wheat (Triticum aestivum) is the most widely grown food crop in the world threatened by future climate change. In this study, we simulated climate change impacts and adaptation strategies for wheat globally using new crop genetic traits (CGT), including increased heat tolerance, early vigor to increase early crop water use, late flowering to reverse an earlier anthesis in warmer conditions, and the combined traits with additional nitrogen (N) fertilizer applications, as an option to maximize genetic gains. These simulations were completed using three wheat crop models and five Global Climate Models (GCM) for RCP 8.5 at mid-century. Crop simulations were compared with country, US state, and US county grain yield and production. Wheat yield and production from high-yielding and low-yielding countries were mostly captured by the model ensemble mean. However, US state and county yields and production were often poorly reproduced, with large variability in the models, which is likely due to poor soil and crop management input data at this scale. Climate change is projected to decrease global wheat production by −1.9% by mid-century. However, the most negative impacts are projected to affect developing countries in tropical regions. The model ensemble mean suggests large negative yield impacts for African and Southern Asian countries where food security is already a problem. Yields are predicted to decline by −15% in African countries and −16% in Southern Asian countries by 2050. Introducing CGT as an adaptation to climate change improved wheat yield in many regions, but due to poor nutrient management, many developing countries only benefited from adaptation from CGT when combined with additional N fertilizer. As growing conditions and the impact from climate change on wheat vary across the globe, region-specific adaptation strategies need to be explored to increase the possible benefits of adaptations to climate change in the future.info:eu-repo/semantics/publishedVersio

Efeitos de períodos de descanso fixo e variável no acúmulo de forragem e estrutura do dossel de capim-bermuda 'Jiggs' e 'Tifton 85' sob pastejo

The objective of this work was to evaluate the effects of variable and fixed rest periods on the forage production, plant-part composition, and canopy structural characteristics of 'Tifton 85' and 'Jiggs' Bermuda grass (Cynodon spp.) pastures under rotational stocking. The treatments were two grass cultivars (Jiggs and Tifton 85) and two rest periods (grazing starting whenever the canopy reached 25 cm or every 28 days, regardless of canopy height). A completely randomized experimental design, with a 2×2 factorial arrangement (two grass cultivars and two managements), was used with three replicates. The experiment was carried out during the summer growing season in Piracicaba, SP, Brazil. Pre- and post-grazing forage mass chacteristics were evaluated. 'Jiggs' and 'Tifton 85' canopies had similar light interception (96.8%) at pre-grazing, for fixed and variable rest periods; however, they showed different canopy structural characteristics. 'Jiggs' had greater stem proportion, greater canopy height during pre-grazing, and lower leaf area index. There were no differences between strategies and between grass cultivars for total yield, which averaged 16.8 Mg DM ha-1. Fixed and variable rest periods can be used for 'Tifton 85' and 'Jiggs' Bermuda grass.O objetivo deste trabalho foi avaliar os efeitos do uso de períodos de descanso fixo e variável sobre a produção de forragem, a composição morfológica e as características estruturais de dosséis dos pastos de capim‑bermuda 'Tifton 85' e 'Jiggs' (Cynodon spp.), sob lotação rotacionada. Os tratamentos consistiram de duas cultivares de capim (Jiggs e Tifton 85) e dois períodos de descanso (pastejo sempre que o dossel atingisse 25 cm ou a cada 28 dias, independentemente da altura do dossel). Utilizou-se o delineamento inteiramente casualizado, em arranjo fatorial 2x2 (duas cultivares de capim e dois manejos), com três repetições. O experimento foi realizado durante o cultivo de verão, em Piracicaba, SP. Avaliaram-se as características de massa de forragem no pré- e no pós-pastejo. Dosséis de 'Jiggs' e 'Tifton 85' apresentaram valor similar de interceptação da radiação incidente (em média, 96,8%) no pré-pastejo, nos períodos de descanso fixo e variável; no entanto, apresentaram diferenças quanto às características estruturais do dossel. 'Jiggs' apresentou maior proporção de colmo, maior altura do dossel no pré-pastejo e menor índice de área foliar. Não houve differenças entre as estratégias de pastejo e entre as cultivares quanto ao acúmulo total de forragem, que obteve produção média de 16.8 Mg ha-1 MS. Os períodos de descanso fixo e variável podem ser utilizados para os capins 'Tifton 85' e 'Jiggs'

Spatial distribution of equine seroreagent to Leptospira spp. in Northeastern Brazil

Considering the importance of leptospirosis in both equine husbandry and public health, as well as the relevance of knowledge of current serogroup and the small number of studies addressing this disease in equines in Northeastern Brazil, the present study performed a serological survey of Leptospira spp. in a serum bank of 1,267 equines originating from 177 municipalities, located in four states in Northeastern Brazil: Ceará, Rio Grande do Norte, Paraíba and Pernambuco. The microscopic agglutination test (MAT) was used for diagnosis of leptospirosis using 24 serovars as antigens. The frequency of reagent equines was 29.7% (376/1,267), and 68.9% (122/177) of municipalities had at least one positive reaction. The serogroups reagent were Australis (37.2%), Icterohaemorrhagiae (29.3%), Tarassovi (9.6%), Sejroe (5.8%), Pomona (5.3%), Grippotyphosa (4.5%), Pyrogenes (2.4%), Bataviae (1.9%), Ballum and Hebdomadis (1.3%), Mini (0.5%), Celledoni, Shermani, and Javanica (0.3% each). There were significant statistical differences regarding sex and age, with a higher frequency in females (P= 0.014), and in animals ≥ 6 years (P=0.001). We concluded that seropositivity to Leptospira spp. is high in equines in Northeastern Brazil, with a predominance of serologic reactions to the Australis serogroup in the border areas between the states, and the Icterohaemorrhagiae serogroup in coastal areas or their vicinity. The high degree of seropositivity found points to the need to implement prophylactic strategies, both intraspecies infection prophylaxis and rodent control. We also recommended avoiding animal crowding and separating animals according to sex and age group during handling.Considerando a importância da leptospirose na equinocultura e na saúde pública, bem como a relevância do conhecimento dos sorogrupos circulantes e do pequeno número de estudos realizados sobre esta doença em equinos no Nordeste do Brasil, o presente trabalho foi delineado para realizar um inquérito sorológico de Leptospira spp. em um banco de soros de 1.267 equinos provenientes de 177 municípios distribuídos em quatro estados: Piaui, Ceará, Paraíba e Pernambuco, localizados na região Nordeste do Brasil. Os soros foram examinados com o teste de Soroaglutinação Microscópica (SAM), utilizando uma coleção de 24 sorovares como antígenos. A frequência de equinos reagentes foi de 29,7% (376 / 1.267) e 68,9% (122/177) dos municípios que tiveram pelo menos uma reação positiva. Os sorogrupos reagentes foram Australis (37,2%), Icterohaemorrhagiae (29,3%), Tarassovi (9,6%), Sejroe (5,8%), Pomona (5,3%), Grippotyphosa (4,5%), Pyrogenes (2,4%), Bataviae (1,9%), Ballum e Hebdomadis (1,3%), Mini (0,5%), Celledoni, Shermani e Javanica (0,3%). Houve diferenças estatisticamente significantes quanto ao sexo e idade, com maior frequência no sexo feminino (P = 0,014) e no animal com idade ≥ 6 anos (P = 0,001). Conclui-se que a infecção por Leptospira spp. tem ocorrência significativa em equídeos do Nordeste do Brasil, com predominância de reações para o sorogrupo Australis nas áreas de fronteira entre os estados e para sorogrupo Icterohaemorrhagiae nas áreas litorâneas ou em suas proximidades. O alto grau de soropositividade encontrado aponta para a necessidade da implementação de estratégias profiláticas tanto intraespécies quanto relacionadas ao controle de roedores. Também recomenda-se evitar superlotações de animais em piquetes e manejá-los em grupos de acordo com o sexo e a faixa etária

Optimizing Winter Wheat Resilience to Climate Change in Rain Fed Crop Systems of Turkey and Iran

Erratic weather patterns associated with increased temperatures and decreasing rainfall pose unique challenges for wheat breeders playing a key part in the fight to ensure global food security. Within rain fed winter wheat areas of Turkey and Iran, unusual weather patterns may prevent attaining maximum potential increases in winter wheat genetic gains. This is primarily related to the fact that the yield ranking of tested genotypes may change from one year to the next. Changing weather patterns may interfere with the decisions breeders make about the ideotype(s) they should aim for during selection. To inform breeding decisions, this study aimed to optimize major traits by modeling different combinations of environments (locations and years) and by defining a probabilistic range of trait variations [phenology and plant height (PH)] that maximized grain yields (GYs; one wheat line with optimal heading and height is suggested for use as a testing line to aid selection calibration decisions). Research revealed that optimal phenology was highly related to the temperature and to rainfall at which winter wheat genotypes were exposed around heading time (20 days before and after heading). Specifically, later winter wheat genotypes were exposed to higher temperatures both before and after heading, increased rainfall at the vegetative stage, and reduced rainfall during grain filling compared to early genotypes. These variations in exposure to weather conditions resulted in shorter grain filling duration and lower GYs in long-duration genotypes. This research tested if diversity within species may increase resilience to erratic weather patterns. For the study, calculated production of a selection of five high yielding genotypes (if grown in five plots) was tested against monoculture (if only a single genotype grown in the same area) and revealed that a set of diverse genotypes with different phenologies and PHs was not beneficial. New strategies of progeny selection are discussed: narrow range of variation for phenology in families may facilitate the discovery and selection of new drought-resistant and avoidant wheat lines targeting specific locationsinfo:eu-repo/semantics/publishedVersio

Hexapoda Yearbook (Arthropoda: Mandibulata: Pancrustacea) Brazil 2020: the first annual production survey of new Brazilian species

This paper provided a list of all new Brazilian Hexapoda species described in 2020. Furthermore, based on the information extracted by this list, we tackled additional questions regarding the taxa, the specialists involved in the species descriptions as well as the journals in which those papers have been published. We recorded a total of 680 new Brazilian species of Hexapoda described in 2020, classified in 245 genera, 112 families and 18 orders. These 680 species were published in a total of 219 articles comprising 423 different authors residing in 27 countries. Only 30% of these authors are women, which demonstrates an inequality regarding sexes. In relation to the number of authors by species, the majority of the new species had two authors and the maximum of authors by species was five. We also found inequalities in the production of described species regarding the regions of Brazil, with Southeast and South leading. The top 10 institutions regarding productions of new species have four in the Southeast, two at South and with one ate North Region being the outlier of this pattern. Out of the total 219 published articles, Zootaxa dominated with 322 described species in 95 articles. The average impact factor was of 1.4 with only seven articles being published in Impact Factors above 3, indicating a hardship on publishing taxonomic articles in high-impact journals.The highlight of this paper is that it is unprecedent, as no annual record of Hexapoda species described was ever made in previous years to Brazil.Fil: Silva Neto, Alberto Moreira.

Evidence for increasing global wheat yield potential

Wheat is the most widely grown food crop, with 761 Mt produced globally in 2020. To meet the expected grain demand by mid-century, wheat breeding strategies must continue to improve upon yield-advancing physiological traits, regardless of climate change impacts. Here, the best performing doubled haploid (DH) crosses with an increased canopy photosynthesis from wheat field experiments in the literature were extrapolated to the global scale with a multi-model ensemble of process-based wheat crop models to estimate global wheat production. The DH field experiments were also used to determine a quantitative relationship between wheat production and solar radiation to estimate genetic yield potential. The multi-model ensemble projected a global annual wheat production of 1050 ± 145 Mt due to the improved canopy photosynthesis, a 37% increase, without expanding cropping area. Achieving this genetic yield potential would meet the lower estimate of the projected grain demand in 2050, albeit with considerable challenges.Fil: Guarin, Jose Rafael.

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
