Recent discoveries in microbiota dysbiosis, cholangiocytic factors, and models for studying the pathogenesis of primary sclerosing cholangitis
Authors: Huang Yu , Zhang Shuai , Weng Jie-Feng , Huang Di , Gu Wei-Li
Published: May 2022

Primary sclerosing cholangitis (PSC) is a cholangiopathy caused by genetic and microenvironmental changes, such as bile homeostasis disorders and microbiota dysbiosis. Therapeutic options are limited, and proven surveillance strategies are currently lacking. Clinically, PSC presents as alternating strictures and dilatations of biliary ducts, resulting in the typical “beaded” appearance seen on cholangiography. The pathogenesis of PSC is still unclear, but cholangiocytes play an essential role in disease development, wherein a reactive phenotype is caused by the secretion of neuroendocrine factors. The liver–gut axis is implicated in the pathogenesis of PSC owing to the dysbiosis of microbiota, but the underlying mechanism is still poorly understood. Alterations in cholangiocyte responses and related signalling pathways during PSC progression were elucidated by recent research, providing novel therapeutic targets. In this review, we summarise the currently known underlying mechanisms of PSC pathogenesis caused by the dysbiosis of microbiota and newly reported information regarding cholangiocytes in PSC. We also summarise recently reported in vitro and in vivo models for studying the pathogenesis of PSC.
Analysis of pore morphology in oxide electroceramics by automatic image analysis
Authors: Schuster Alexander , Schulz Josef , Fischer Simon , Liersch Antje
Published: May 2022

Porosity represents one of the key parameters in the characterization of ceramic materials. Pores remaining after sintering often constitute the origin of direct mechanical or dielectric material failure. Isolated and large-scale pores in the microstructure are particularly problematic; many times these are larger than the average pore diameter. Their detection poses a particular challenge for analytics. The analytical methods used for ceramic materials either detects only part of the porosity or are greatly limited in view of area measurements. Moreover, the analysis of the morphology of detected pores is hardly possible or even impossible for the majority of methods.

This research paper offers a detailed account of the qualitative analysis of porosity in oxide ceramics, with the primary focus being on possibilities for pore detection, the measured distribution functions, and the advantages of this method. This paper will show that the use of digital light microscopy together with coaxial illumination is capable of determining pore morphology and distribution in a fraction of time that would be required by conventional methods. The comparison of the measurement results, aided by well established methods for pore characterization, such as the linear intercept method (according to DIN EN ISO 13383), will enable a reliable validation of the results. Final FESEM analysis was used to enable a detailed study of the identified pores and to verify the results.
Heat Treatment Tests for Reduction of Delta Phase in Alloy 718
Authors: Neidel Andreas , Giller Madeleine , Fischer Boromir
Published: May 2022

Large hot-rolled rings made of Alloy 718 were used as semi-finished product for turbomachinery components. Samples taken from one such ring exhibited non-uniform mechanical properties, partly below specified limits. Too high a volume fraction of delta phase in the microstructure was identified as the metallurgical root cause of failure. The case study presented in this contribution shows that such deviation from specified material properties does indeed constitute component failure, since the subject raw forging could not be used as is for fabrication of rotating equipment for gas turbine engines. To salvage the subject part and avoid having to scrap it at high cost, successful heat treatment tests were performed in the laboratory with the aim of eliminating delta phase to an extent, sufficient for property recovery. Heat treatment parameters were derived and recommended to the client. They were successfully applied before final machining and the subject hot-rolled ring was salvaged.

Authors: Panneerselvam Vivekanandan , Mohd Turan Faiz
Published: May 2022

Plastics have been heavily used in industries like automobile, manufacturing, electrical and electronics industry all over the world. Injection molding is one of the ways to process plastics polymers. However, one of the difficulties they have to face is to set the optimal parameter for the injection molding process. Incorrect parameter selection can lead to parts defects such as warpage, shrinkage, sink marks, weld marks and so on. In this study, the optimal process parameter of injection molding for manufacturing of plastic pallets which is used for warehousing was determined by the orthogonal array of Taguchi’s L9 which has 3 factors and 3 levels for each factor, experimental design, and Regression Analysis. The three main parameters such as Mold temperature, holding pressure and charging speed were choosen to study their effect on the Compressive strength. S/N ratios were utilized for determining the optimal set of parameters. According to the results, 230 °C of mold temperature, 98 RPM of charging speed, 25 MPa of Holding pressure make the products in the shape and proportion of the product satisfactory. Statically the most significant parameters were found to be as mold temperature and Charging speed for the Polypropylene moldings, respectively. Holding pressure had the least effect on the compressive strength of PP material. After the degree of significance of the studied process parameters was determined, the linear Regression model was generated and was shown to be an effective predictive tool for Compressive strength.

Published: May 2022

In this work, EFB fibers / Polypropylene matrix were prepared using hot pressing tool at 3 different ratio (5%, 10%, and 15% EFB/PP). Tensile test and impact test were done according to ASTM standard, ASTM D638 and ASTM D256, respectively. The results from tensile test and impact test showed that the prepared specimens of EFB/PP composite have slightly higher elastic modulus (1.95 GPa - 2.1 GPa) compared to pure PP (1.91 GPa) but at the same time they are lack of ductility and have low impact strength, at a range of 4.6 kJ/m2 to 5.5 kJ/m2 compared to pure polypropylene with impact strength value of 18.18 kJ/m2. From the fractured surface analysis, the initial micro cracks were seen mostly occurred at the interface of the EFB/PP and air voids which act as a crack propagation site.

Dialogue System Augmented with Commonsense Knowledge
Authors: Lasy Ilya , Marcinkevičius Virginijus
Published: May 2022

Building an open-domain dialog system is a challenging task in current research. In order to successfully maintain a conversation with human, a dialog system must develop many qualities: being engaging, empathetic, show a unique personality and having general knowledge about the world. Prior research has shown that it is possible to develop such chat-bot system that combines these features, but this work explores this problem further. Most state-of-theart dialogue systems are guided by unstructured knowledge such as Wikipedia articles, but there is a lack of research on how structured knowledge bases can be used for open-domain dialogue generation. This work proposes usage of structured knowledge base ConceptNet for knowledge-grounded dialogue generation. Novel knowledge extraction algorithm is proposed which is then used to incorporate knowledge into existing dialogue datasets. Current state-of-theart model BlenderBot is finetuned on new datasets which shows improvement in novelty of utterances generated by the model.

Intergenerational Social Mobility in Lithuania: Different Perspectives of Measurement
Authors: Vencius Tautvydas
Published: May 2022

Both scholarly analyses and main political documents have not focused enough on research into social mobility in Lithuania. Such a case is partly understandable as the issue of ensuring social mobility has never been a prevailing one on the political agenda. This article seeks to describe different perspectives on measuring social mobility between generations in Lithuania and to present their empirical expressions. Intergenerational mobility is understood as the difference between the socio-economic situation of parents and adult children, i. y. a comparison of the person’s current circumstances with those from which the person originated. Social positions that can be compared are usually based on occupational, income, education or other social class or socio-economic situation schemes. This article is based on European Social Survey data from wave 9 and reviews the intergenerational social mobility of 1970-1984 generation in terms of education, occupations, income and health dimensions.. The results show that occupational and educational mobility increases between generations. There has been a significant decline in the number of people with only a basic education and at the lowest levels of the occupational scale. However, there is a lack of data on intergenerational social mobility in health and income. Therefore, conclusions about this mobility can only be drawn from the work of previous researchers. Intergenerational mobility can also be a tool to achieve greater economic efficiency. Low intergenerational mobility may mean that some individuals are unable to realize their talents due to their low socio-economic status. Therefore, in the light of the findings of the study, it would make sense to consider developing a social mobility strategy.
Extraposed relative clauses in Role and Reference Grammar. An analysis using Tree Wrapping Grammars
Authors: Kallmeyer Laura
Published: May 2022

This paper proposes an analysis of extraposed relative clauses in the framework of Role and Reference Grammar (RRG), adopting its formalization as a tree rewriting grammar, specifically as a Tree Wrapping Grammar (TWG). Extraposed relative clauses are a puzzle since the link to the antecedent noun can be rather non-local but it seems nevertheless appropriate to model it as a syntactic dependency and not a purely anaphoric relation. Moreover, certain types of determiners require their NP to be modified by a (possibly extraposed) relative clause, and any comprehensive framework should account for this. We show that the tree wrapping operation of TWG, which is conventionally used to fill argument slots out of which some elements have been extracted, can be used to model extraposed relative clauses. The analysis accounts for the non-locality of the phenomenon while capturing the link to the antecedent NP in a local way (i.e., within a single elementary tree).

Authors: Lim Wei Juan , Ow Ji Ken , Cheong Xian Pei , bin Nordin Rusli , Lee Chuey Yan
Published: May 2022

Background: The Global Registry of Acute Coronary Syndrome (GRACE) risk score is used to provide an estimate of 6-month mortality among patients admitted for acute coronary syndrome (ACS). Methods: This study validated the GRACE score in a contemporary cohort of 428 patients aged ≥18 years admitted to Hospital Sultanah Aminah Johor Bahru between January and April 2018 for ACS. The survival status of patients 6 months after hospital discharge was calculated using the GRACE risk score, and the validity of the GRACE risk score was evaluated by assessing its calibration (Hosmer–Lemeshow test) and discriminatory capacity. Results: Of the 428 patients in this study, 92 (21.5%) were admitted for ST-elevation MI (STEMI), 128 (29.9%) were admitted for non-STEMI and 208 (48.6) were admitted for unstable angina. By 6 months after discharge, 66 (15%) patients had died. The GRACE risk score was calibrated and validated, showing an adequate capacity for discrimination with a receiver operating characteristic area under the curve of 0.831 (95% CI [0.778–0.884]; p<0.001). Conclusion: This study validated the GRACE score for predicting 6-month mortality among patients admitted to an Asian medical centre for ACS and recommended that it is used routinely.

A rapid and simple ultra-performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) method was developed and validated for simultaneous determination of six analytes from the Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. leaves (ESL) in beagle dog plasma for the first time, including 3-O-α-l-rhamnopyranosyl-(1→2)-α-l-arabinopyranoside-29-hydroxy oleanolic acid, 3-O-β-d-glucopyranosyl-(1→2)-α-l-arabinopyranoside-29-hydroxy oleanolic acid, 3-O-β-d-glucopyranosyl-(1→2)-α-l-arabinopyranosyl-30-norlean-12,20 (29) –dien-28-olic acid, ciwujianoside E, guaianin N, and eleutheroside K. The chromatographic separation was performed using an ACQUITY UPLC BEH C18 column (2.1 × 100 mm, 1.7 μm) using a gradient elution way with a mobile phase of acetonitrile-water containing 0.1% formic acid. Analytes were detected on a triple-quadrupole mass spectrometer equipped with an electrospray ionization (ESI) source with multiple reaction monitoring (MRM) mode. Calibration curves were all linear (r ≥ 0.9933) over the concentration range. The mean extraction recoveries and matrix effect of analytes and I.S. were ranged from 80.26% to 98.32% and from 91.27% to 111.67%, respectively. The intra-day and inter-day precision were ranged from 2.20% to 14.81%, and the accuracy range was 1.60–14.60%. The analytical method was successfully applied for the pharmacokinetic characteristics of the six analytes in beagle plasma after oral administration of ESL extracts. The T1/2 of six analytes was more than 3.09 ± 0.78 h.

Using nature-based solutions to support urban regeneration: A conceptual study
Authors: He Qingchang , Reith Andras
Published: May 2022

Nature-based solutions use a holistic viewpoint to address social challenges while providing environmental, social and economic benefits simultaneously. The Victoria Quay is a historical space with complex social and environmental issues. This study uses an investigation-oriented method to explore the re-planning strategies. The environmental problems are addressed by extending the green infrastructure into the site to recover the ecological corridor and alleviate flooding risks. The originally single land-use type is changed, and several historical buildings are transformed into landmarks to improve the connection with city center by linking the ‘golden route’. All the proposed measures tried to reactivate the various relationships rather than merely renew the Victoria Quay.

As neblinas de Diadorim
Authors: Soares Claudia Campos
Published: May 2022

Resumo Um aspecto de Grande sertão: veredas que tem sido pouco observado pela crítica diz respeito à utilização de estratégias que criam o efeito de suspense na narrativa. Riobaldo, o narrador-protagonista do livro, faz seguidamente afirmações descontextualizadas e ou vagas, sugerindo, ou mesmo afirmando, que elas se referem a acontecimentos determinantes de sua vida. Ao modo das narrativas de suspense, portanto, Riobaldo propõe mistérios e adia o seu esclarecimento. É o que ocorre em relação a Diadorim. Durante praticamente toda a narrativa, o ex-jagunço aponta comportamentos inusuais de seu companheiro dos tempos de jagunçagem e insinua, ou mesmo explicita, que este escondia segredos insuspeitáveis, de que só tardiamente teria tomado conhecimento. E promete que esses segredos serão revelados oportunamente. Esse suspense criado em torno da figura de Diadorim encontrará, ao final do livro, algum tipo de revelação, mas muito relativa. O esclarecimento oferecido não satisfaz o desejo do entendimento pleno, não fecha a questão; ao contrário, traz novas perguntas e mistérios. Este trabalho propõe-se a discutir alguns aspectos dessa estratégia e suas possíveis funções na narrativa.

Resistir na língua: a literatura indígena contra o silenciamento monolíngue
Authors: Cernicchiaro Ana Carolina
Published: May 2022

Resumo O presente trabalho propõe pensar a linguagem como terreno sobre o qual o colonialismo, a biopolítica e a necropolítica construíram suas bases, tanto porque a posse do logos é o que fundamenta a partilha do sensível e estabelece a cesura entre os que compartilham um comum e a parte dos sem parte, entre existência política e vida nua, quanto porque o monolinguismo é a engrenagem essencial da máquina colonial que, ainda hoje, mata idiomas e silencia histórias. Contra esse projeto excludente da língua nacional, a literatura indígena resiste com um devir-menor da língua maior, capaz de desestabilizar a unicidade do idioma, da história, da literatura e do próprio conceito de Povo brasileiro.

Resumo Este artigo estuda a representação dos anos finais da colonização portuguesa em Lourenço Marques (atualmente Maputo, capital de Moçambique) na obra literária Caderno de memórias coloniais (2009), da escritora Isabela Figueiredo. Trata-se de analisar a escrita colonial a partir da perspectiva de duas gerações distintas: o pai colonialista e a filha progressista. O romance acolhe os embaralhamentos promissores das escritas de si e dos paratextos, jogando luz nas interfaces entre a escrita individual e a memória coletiva portuguesa de um trauma nacional. Em sua tessitura romanesca, Figueiredo busca fugir dos perigos da história única (ADICHIE) e escreve, como ensina Walter Benjamin, uma história a contrapelo.

Resumo Neste artigo, apresentamos um breve resumo da análise crítica feita por Jean-Michel Adam e Ute Heidmann (ADAM; HEIDMANN, 2011) de duas versões francesas da narrativa kafkiana sobre quatro mitos de Prometeu, que, uma vez compilada, alterada e publicada por Max Brod, ficou conhecida como Prometheus, em alemão. Trazemos ainda um resumo da discussão feita pelos autores sobre as divergências entre o texto alterado por Brod e o manuscrito original de Kafka, que diverge do primeiro. Em seguida, elencamos duas traduções consagradas em português, duas em espanhol e duas em italiano do texto compilado por Brod. Tais traduções vêm acompanhadas de breves reflexões que fizemos sobre estratégias e decisões dos tradutores. Como suporte teórico, recorremos, na área específica da análise crítica de traduções, à teoria de Reiß (1986) e, no âmbito da poética do traduzir, a Meschonnic (2010) e Borges (1974). Por fim, apresentamos nossa proposta de tradução, em português, para o original de Kafka e o texto alterado por Brod.
Análise experimental da vida útil à fadiga de concretos submetidos à compressão cíclica de baixa frequência
Authors: Felix Emerson Felipe , Carrazedo Rogério , Possan Edna
Published: May 2022

RESUMO A degradação do concreto por fadiga está relacionada a deterioração e danificação do material compósito quando submetido a carregamento cíclico. De modo geral, é observado que a deterioração do material ao ser submetido a ensaios dinâmicos, ocorre semelhantemente ao de concretos avaliados por ensaios estáticos, entretanto, o modo de propagação de fissuras, a velocidade de propagação e o dano podem ser diferentes em função da taxa de carregamento aplicado. Sabendo disso, este trabalho apresenta uma investigação experimental com objetivo de avaliar a influência da frequência de carregamento, intensidade da carga e resistência à compressão do material, no comportamento à fadiga do concreto. Ensaios foram realizados considerando três frequências de carregamento (0,125, 0,25 e 0,5 Hz), dois níveis de tensão máxima (50% e 70% da resistência à compressão) e concretos com três classes de resistência (30, 50 e 70 MPa). Os resultados encontrados apontam que à medida que a frequência de carregamento é aumentada, a vida útil à fadiga cresce exponencialmente. No entanto, observou-se que a vida útil à fadiga é menor em concretos de alta resistência, e que a vida útil à fadiga possui uma relação inversa com a resistência à compressão.

Published: May 2022

Abstract The current study was conducted to examine the point prevalence of gastrointestinal parasites of migratory quails. Due to its economic importance, the control of ascaridiosis is critical. Migration of birds is considered to enhance the global spread and cross-species transmission of pathogens. The current study was aimed to detect A.galli in migratory quails, a potential contributory risk factor for transmission of this parasite to local birds. A total of 230 migratory quails were trapped using nets from migratory routes in Balochistan and examined under the compound microscope for the presence of A. galli. Conventionally, A. galli was identified by its morphology with the presence of three large lips and absence of posterior esophageal bulb. Results revealed that out of 230, 120 (52.17%) quails were positive for A. galli by targeting COX1 gene (533 bp) by using conventional PCR. Further, the amplicon was sequenced which showed 99% similarity with A. galli publically available in NCBI Gen Bank. Phylogenetic analysis of sequences of our isolated parasite indicated the close relationship with A.galli isolated from chickens. In conclusion migratory quails and other migratory birds may play a key role in spreading and transmission of these parasites and other pathogens to domestic chicken. Therefore, strict biosecurity measures should be adopted especially for commercial poultry farms.

Published: May 2022

ABSTRACT The action of photosystem I (PSI) inhibiting herbicides depends on light to cause oxidative stress in plants. However, their translocation is inhibited due to their rapid action in the presence of light. The aim was to evaluate the efficacy of the herbicide diquat for control of corn plants subjected to different periods of absence of light after application. Two experiments (field and greenhouse) were conducted, applying the herbicide diquat (200 g a.i. ha−1) to maize plants at stage V4. The plants were subjected to different periods of absence of light after diquat application: 0; 1; 2; 3; 4; 5 and 6 hours. A treatment without herbicide application was used as a control. The control (%) and biomass of corn plants were evaluated in both experiments, and photosynthetic activity and hydrogen peroxide (H2O2) accumulation in leaves were evaluated in the greenhouse experiment. The results showed that diquat needs at least 5 hours of absence of light after application to fully control corn plants. The plants recovered when using shorter periods (4 hours or less) of darkness, and injuries were restricted to points where the herbicide had contact with the plant. The ability of plants to recover was related to the higher photosynthetic activity and oxidative stress induction due to early light exposure. Thus, the lower production of H2O2 in plants kept in the dark for longer periods after herbicide application allows the translocation of the herbicide to meristems, which prevents regrowth of corn plants.

ABSTRACT Sour passion fruit is a fruit crop widely cultivated throughout Brazil, due to its adaptation to the tropical climate. However, in semi-arid regions its development is limited by the high concentration of soluble salts in the waters commonly used in irrigation. In this context, exogenous application of low concentrations of hydrogen peroxide can attenuate the damage caused by salt stress. The objective of this study was to evaluate electrolyte leakage, photosynthetic pigments and photochemical efficiency in sour passion fruit cv. BRS Rubi do Cerrado under irrigation with saline waters and foliar application of hydrogen peroxide. A completely randomized design was used, with treatments arranged in split plots, corresponding to five levels of irrigation water salinity - ECw (0.6; 1.2; 1.8; 2.4 and 3.0 dS m−1) and four concentrations of hydrogen peroxide - H2O2 (0; 15; 30 and 45 μM of H2O2) in plots and subplots, respectively. Irrigation with saline water reduced chlorophyll a and total chlorophyll contents of sour passion fruit plants cv. BRS Rubi do Cerrado, at 240 days after transplanting. Hydrogen peroxide at concentration of 15 μM stimulated chlorophyll a and total chlorophyll biosynthesis and, at 45 μM, relieved the effect of 3.0 dS m−1 water salinity on electrolyte leakage in the leaf blade of sour passion fruit. Salt stress did not affect the initial, maximum, variable fluorescence and quantum efficiency of photosystem II of sour passion fruit cv. BRS Rubi do Cerrado.

ABSTRACT Biological aspects and predatory capacity of Doru luteipes was assessed as a function of predation on Spodoptera frugiperda. The experiment was conducted under laboratory conditions of mean temperature of 25 ± 1 °C, relative humidity of 70 ± 10%, and 12:12 h (Light: Dark) photoperiod. To evaluate the biological parameters of D. luteipes, artificial diet, eggs and caterpillar (1st, 2nd, 3rd, 4th, 5th or 6th instars) of S. frugiperda were supplied. The completely randomized statistical design was used, with 10 replicates for each treatment. The nymphs (1st, 2nd and 3rd instars) and adult males and females of D. luteipes were individualized in Petri dish (9 cm diameter), with artificial diet as standard food (control). Nymphs of the 1st and 3rd instars of the predator lasted 4.5 and 6.9, days respectively, but they perished. The survival of D. luteipes is high, but there was variation when consuming the different instars of the caterpillar of S. frugiperda. Adults of D. luteipes did not consume caterpillars of the 4th, 5th and 6th instars of the prey. There was a significant difference for the feeding of D. luteipes with artificial diet, eggs and caterpillar of S. frugiperda with respect to the parameters number of eggs and preoviposition. Higher consumption of male and female D. luteipes occurs when they are fed with prey eggs.
A sustentabilidade fiscal e a oferta de serviços públicos: uma análise dos municípios brasileiros de pequeno porte

Published: May 2022

Resumo Em 2019, o Governo Federal enviou ao Senado a proposta de Emenda à Constituição nº 188/2019, denominada PEC do Pacto Federativo. Entre outras medidas, a PEC propõe incluir um dispositivo que obriga os municípios de até 5 mil habitantes a comprovar sua “sustentabilidade financeira”, definida como ter pelo menos 10% da receita total proveniente de impostos municipais. Tendo como universo de análise os pequenos municípios brasileiros, considerados de baixa sustentabilidade financeira, segundo os critérios estabelecidos pela PEC 188/2019, este trabalho busca avaliar o nível de eficácia da prestação de serviços públicos municipais, de modo a avaliar a real necessidade que justifica essa proposta de emenda. Como contraponto à avaliação meramente demográfica e/ou tributária foram analisados três indicadores de cobertura da prestação de serviços básicos tipicamente municipais: assistência social, cobertura de saúde e frequência escolar; os quais foram agrupados em um índice síntese denominado Índice de Qualidade de Serviços (IQS). Os resultados mostraram que os indicadores de cobertura dos serviços públicos analisados dos municípios com até 5 mil habitantes possuem desempenho similar aos demais municípios brasileiros, em muitos casos superior à média nacional, diferentemente do suposto na proposta de emenda constitucional. Boa parte dos municípios de pequeno porte populacional (população residente inferior a 5 mil) e de baixa razão de sustentabilidade fiscal (RSF menor que 10%) apresenta melhor desempenho na prestação de serviços públicos. As evidências apresentadas, ainda que preliminares, permitem que se questione a validade do critério de autonomia proposto pela PEC, considerando que as supostas eficiência e eficácia da gestão pública municipal não são resultado exclusivo da suposta “sustentabilidade financeira”.

Abstract: The optimal combination between sowing density and nitrogen (N) fertilization rate is a challenge for the production of high-quality seeds, considering the diversity of genotypes and environments. This study aimed to evaluate the yield and physiological quality of wheat seeds as a function of sowing density and N rate, under different edaphoclimatic conditions. The experiment was carried out in three environments (Londrina, Cascavel, and Ponta Grossa) in a randomized block design with four replications, considering a 2 × 3 × 4 factorial arrangement composed of two genotypes (BRS Anambé and WT 15-025), three sowing densities (250, 350, and 450 seeds.m−2), and four N rates (0, 40, 80, and 120 kg.ha−1). The following seed features were evaluated: yield, first germination count, final seed germination, seedling emergence, emergence speed index, seedling length, and seedling dry matter. Seed yield varied as a function of environment and genotype. BRS Anambé produced seeds with higher physiological quality. The optimal combination between sowing density and N rate that provided the more suitable economic yield, without affecting the physiological quality of wheat seeds, varied with the environment and was estimated in 250 seeds.m−2 × 0 kg.ha−1 N for Londrina and Cascavel, and 350 seeds.m−2 × 18 kg.ha−1 N for Ponta Grossa.

Abstract: Nitric oxide (NO) has been standing out as a seed germination process stimulator, mainly under stress conditions. This work aimed to evaluate the physiological and biochemical effects of NO on germination and vigor of pea seeds submitted to water deficit. Seeds of cv. Itapuã 600 were sown in moistened substrate with water (control), PEG 6000 solution (-0.15 MPa) and PEG 6000 solution with sodium nitroprusside (SNP) (-0.15 MPa + 50 μM), an NO donor. The germination, vigor (germination speed and seedling development), activity of antioxidant enzymes, reactive oxygen species, lipid peroxidation, and amylase activity were evaluated. Germination and vigor of pea seeds were reduced under water deficit, but the application of SNP was able to improve the physiological and biochemical performance of the seeds under this condition. Water deficit promotes an increase in oxidative stress, but the application of NO promotes greater activity of antioxidative apparatus enzymes and amylases, softening the damage caused by water deficit during seed germination and growth of pea seedlings.

Estado e sociedade no Brasil: um encontro adiado com a democracia
Authors: Botelho André , Ferreira Gabriela Nunes
Published: May 2022

RESUMO Três momentos decisivos das relações entre Estado e sociedade no pensamento social e político são abordados: no Império, o debate entre Tavares Bastos e o Visconde do Uruguai; na Primeira República, Oliveira Vianna é o autor central; na transição da ditadura civil-militar de 1964-1985 para a democracia, Raymundo Faoro e Florestan Fernandes são incontornáveis. Se no primeiro momento o debate sobre centralização e descentralização política concentra os interesses, no segundo a questão da adequação das instituições políticas à sociedade é o grande tema; mas, já no terceiro momento, o enfrentamento do problema da democracia nas relações entre Estado e sociedade não poderia ser mais adiado. Traçando esse histórico, no Bicentenário da Independência, queremos repensar impasses dessas relações que permanecem em aberto no presente.
As ciências na formação do Brasil entre 1822 e 2022: história e reflexões sobre o futuro

Published: May 2022

RESUMO Este artigo traça um panorama da história da atuação das ciências no processo histórico de formação do Brasil como nação. Entre 1822 e 2022, os cientistas deram contribuições cruciais ao debate sobre constituição do Estado; identidade nacional; cidadania; visões sobre populações; políticas públicas de saúde e educação; projetos de criação de universidades; circulação internacional de saberes; soberania, desenvolvimento nacional, inserção do Brasil no mundo e convivência entre o atraso e a modernidade. Sugere-se que esses temas centrais em 1822 e 1922 devem ser atualizados na agenda do Bicentenário da Independência. Tal atualização requer uma análise do processo histórico em que se destacam tendências acentuadas pela pandemia de Covid-19: a importância das ciências, e da sustentabilidade da atividade científica, na resposta à crise e aos desafios contemporâneos; a persistência das desigualdades, inclusive as relacionadas ao desenvolvimento científico e tecnológico, e a questão ambiental, transversal e incontornável para todas as áreas do conhecimento.
