Michał Wiszniewski (1794-1865), italianista, studioso e traduttore di Dante
Authors:   Uniwersytet Jagielloński w Krakowie, Pifko-Wadowska Anna
Published: November 2021

This study focuses on Michał Wiszniewski’s interest in Dante. Wiszniewski was a professor of history and literature at the Jagiellonian University of Krakow and was fond of Italy. This work aims to outline Wiszniewski’s contribution to the Polish reception of Dante in the first decades of the 19th century. The study recalls Wiszniewski’s three Italian trips and his book, Podróż do Włoch, Sycylii i Malty (A Journey to Italy, Sicily and Malta), which contains numerous mentions of Alighieri. The main part of the study is dedicated to the analysis of his manuscript Dante Alighieri, kept in the Jagiellonian Library (ms. 948 fasc. 7), which has not been carefully examined until now. This manuscript features an outline of a portion of a literature course taught by Wiszniewski in the 1830s, a lesson concerning the life and work of Dante (particularly the Commedia). The professor describes the two faces of Dante: the scholastic one (in prose) and the poetic one (in verse); explains the poem’s title and the structure of the afterlife; admires the extraordinary plasticity of Dante’s images; and translates into Polish a passage from the Convivio and three episodes from the Inferno. The content of his lesson is compared with other earlier and contemporary Polish studies (of very limited number) on the Poet, as well as with the general trends of Dante criticism of that time and with the Dante scholarship of the Polish Romantic poets. The analysis carried out shows that Wiszniewski’s contribution to Dante studies is, in principle, close to Romantic criticism, but it also follows some Neoclassical trends. In the present study, we do not analyse the article Studia nad Dantem (1847) because of its uncertain attribution (as we try to show).

Abstract It aims on evaluate the effect of the test environment on static fatigue behavior of lithium disilicate-based (LD), and yttrium oxide-stabilized zirconia (YSZ) ceramics. Specimens of LD (IPS e.max CAD, Ivoclar Vivadent) and YSZ (IPS e.max ZirCAD MO, 3 mol% Y2O3, Ivoclar Vivadent) were randomly allocated into three groups: tested in air, inert (paraffin oil, Sigma Aldrich) or distilled water. The static fatigue test (n=15) was performed using a piston-on-three ball assembly, adapted from ISO 6872, as follows: starting load 100 N for LD and 300 N for YSZ; loading application time set to 1 hour for each loading step; step size of 50 N for LD and 100 N for YSZ, applied successively until fracture. Data from static fatigue strength (MPa) and time to fracture (hours) were recorded. Fractographic analysis was executed. Survival analysis corroborates absence of influence of environment on static fatigue outcomes (fatigue strength, time to fracture and survival rates) for YSZ. For LD, specimens tested in air presented statistically superior survival rate and static fatigue strength (p= 0.025). In regards of time to fracture, LD tested in air were superior than when tested in distilled water (p=0.019) or inert (p=0.017) environments. No statistical differences for Weibull modulus were observed. Failures started on the tensile stress surface. Thus, the test environment did not affect slow crack growth (SCG) mechanisms during static fatigue test of YSZ ceramics, but it plays a significant role for the static fatigue behavior of lithium disilicate-based glass ceramics, indicating a high susceptibility to SCG.

Abstract This in vitro study evaluated the effect of the beam homogeneity of a multiple-peak light-curing unit on the surface microhardness and the effect of toothbrushing wear on the microhardness, surface roughness, roughness profile, volume loss, and gloss retention of incremental and bulk-fill resin-based composites (RBCs). A LED light-curing unit (VALO) with four LEDs at the tip end (405, 445, 465A, and 465B nm emission peak) was used according to each manufacturer-recommended time to obtain disks (n=10) of six RBCs: Estelite Sigma Quick, Charisma Classic, Tetric EvoCeram Bulk Fill, Filtek Z250, Filtek Supreme Ultra, and Filtek Bulk Fill. Microhardness values were obtained according to each LED positioning of the light-curing unit on the top surface of the RBCs and were analyzed before and after toothbrushing regarding microhardness, surface roughness, roughness profile, volume loss, and gloss retention. Microhardness was considered homogeneous on the top surface regardless of the type of RBC or wavelength tested (p>0.05). Overall, toothbrushing did not reduce the microhardness of the RBCs but influenced the gloss values for most RBCs (p<0.001). Charisma Classic presented the greatest surface roughness and roughness profile after toothbrushing (p<0.05). Volume loss did not differ among RBCs (p>0.05). In conclusion, different wavelengths of the LED did not affect the top surface microhardness, regardless of the RBCs tested; and bulk-fill composites presented similar surface changes (microhardness, surface roughness, roughness profile, volume loss, and gloss retention) when compared to conventional composites after toothbrushing.

Abstract This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administered for 48 hours, starting 1 hour before the in-office bleaching. Two bleaching sessions were performed with 35% hydrogen peroxide gel with 1-week interval. TS was recorded up to 48 hours after dental bleaching with a 0-10 visual analogic scale (VAS) and a 5-point numeric rating scale (NRS). The color was evaluated with VITA Classical and VITA Bleachedguide scales (ΔSGU) and VITA Easyshade spectrophotometer (ΔE*ab and ΔE00). The absolute risk of TS in both groups was evaluated using Fischer's exact test. Comparisons of the TS intensity (NRS and VAS data) were performed by using the Mann-Whitney test and a two-way repeated measures ANOVA, respectively. The color alteration between the groups was compared with the Student's t test. The significance level was 5%. There was no statistically significant difference between the groups for the absolute risk of TS (p = 1.00) or for the intensity of TS (p > 0.05). A bleaching of approximately 7 shade guide units was observed on the Vita Classical and Vita Bleachedguide scales, with no statistical difference between the groups. It was concluded that coadministration of ibuprofen and caffeine did not reduce the absolute risk or intensity of TS and did not interfere with the efficacy of dental bleaching.

Abstract The host defense response to microbial challenge emerging from the root canal system leads to apical periodontitis. The aim of this study was to evaluate the expression of inflammatory cytokines and Nitric Oxide (NO) by macrophages after interaction with Enterococcus faecalis in the: plankton and dislodged biofilm mode; intact biofilm mode stimulated by calcium hydroxide (CH), CH and chlorhexidine (CHX) or Triple Antibiotic Paste (TAP). For this purpose, culture of macrophages from monocytes in human peripheral blood (N=8) were exposed to the different modes of bacteria for 24 hours. Subsequently, the cytokines, such as, Tumor Necrotic Factor- alfa (TNF-α), interleukin (IL)-1β, IL-6, IL-10; and NO were quantified by Luminex xMAP and Greiss reaction, respectively. In addition to the potential therapeutic effects of the intracanal medication, their antimicrobial activity against Enterococcus faecalis biofilm were also tested in vitro by confocal microscopy. The experiments` data were analyzed by the Kruskal-Wallis test with the Dunn post hoc test (α < 0.05). Bacteria in dislodged biofilm mode were shown to be more aggressive to the immune system than bacteria in plankton mode and negative control, inducing greater expression of NO and TNF-α. Relative to bacteria in intact biofilm mode, the weakest antimicrobial activity occurred in Group CH. In Groups CH/CHX and TAP the percentage of dead bacteria was significantly increased to the same extent. Interestingly, the biofilm itself did not induce the release of pro-inflammatory cytokines - except for NO - while the biofilm treated with TAP and CH based pastes enhanced the levels of IL-6 and TNF-α; and IL-1 β, respectively. In contrast, the levels of a potent anti-inflammatory (IL-10) were increased in Group TAP.

ABSTRACT: The coati (Nasua nasua, Linnaeus 1766) is a generalist species, feeding on often-discarded human food in dumpsters around ecological tourism sites. We investigated the body weight and some blood chemistry variables related to the diet of wild coatis from three parks: Parque Municipal das Mangabeiras (PM), Parque Nacional do Caparaó (PNC) e Estação Ecológica Água Limpa (EEAL). We tested the plasma of 53 coatis for high-density lipoprotein (HDL), alanine transaminase (ALT), aspartate transaminase (AST), gamma-glutamyl transferase (GGT), cholesterol (Chol), triglycerides (Trig), and alkaline phosphatase (ALP). Male and female adults did not significantly differ on the weight (P > 0.05) and blood chemistry indexes (P > 0.05). The adult coatis of the PM were heavier than the adult coatis of the other two parks. There were significant differences in HDL (P < 0.04), AST (P < 0.001), ALT (P < 0.001), and GGT (P < 0.001) between adults of the three parks. Only ALT and ALP were significantly different (P < 0.05) among the young coatis. The results suggested the coatis of the three parks have different health status. The consumption of discarded human food seems to affect body weight of the PM coatis. The coatis from PNC and EEAL had blood chemistry profiles suggestive of liver disorder. We recommend carrying on environmental education programs to visitors and additional clinical investigations on coatis from these parks.

Abstract This study was carried out to evaluate the effect of Glutamine, as a dipeptide or a free amino acid form, on the progression of burn injuries in rats. Thirty male Wistar rats were burned with a comb metal plate heated in boiling water (98 °C) for three minutes, creating four rectangular full-thickness burn areas separated by three unburned interspaces (zone of stasis) in both dorsum sides. The animals were randomized into three groups (n=10): saline solution (G1-Control) and treated groups that orally received Glutamine as dipeptide (G2-Dip) or free amino acid (G3-FreeAA). Two and seven days after burn injury, lesions were photographed for unburned interspaces necrosis evolution assessment. Seven days after injury, glutathione seric was measured and histopathological analysis was performed. By photographs, there was a significant reduction in necrosis progression in G3-Free-AA between days two and seven. Histopathological analysis at day 7 showed a significantly higher stasis zone without necrosis and a higher number of fibroblasts in G2-Dip and G3-FreeAA compared with G1-Control. Also, glutathione serum dosage was higher in G2-Dip. The plasmatic glutathione levels were higher in the G2-Dip than the G1-Control, and there was a trend to higher levels in G3-FreeAA. The reduction in histological lesions, greater production of fibroblasts, and greater amounts of glutathione may have benefited the evolution of burn necrosis, which showed greater preservation of interspaces.
Nomes e pronomes na Língua Portuguesa: a questão sexista no idioma e na academia
Authors: Nodari Sandra
Published: November 2021

Resumo: Neste ensaio, discuto a invisibilidade de pesquisadoras por conta das normas da Língua Portuguesa e das normas de referenciação das publicações acadêmicas pelo viés de gênero com relação à creditação de mulheres. É regra geral, com exceção de algumas revistas feministas, que autores e autoras sejam apresentados em artigos, dissertações e teses pelo sobrenome, o que pode reduzir a percepção das mulheres que são citadas em pesquisas científicas. As discussões com relação ao sexismo do idioma, trazidas por vezes pela imprensa a partir de discussões sociais, são considerações aqui tratadas. A pergunta que surge é se pode haver um movimento de revisão da forma de creditar as mulheres em trabalhos científicos. Para tanto, após a revisão da literatura, haverá uma proposta de que a creditação das autoras mulheres seja feita de forma completa, com nome, sobrenome e uso dos pronomes adequados.

Abstract The objective of this study was to evaluate the effect of using increasing levels of cassava root meal in the diet of broilers, estimated by the performance and yield of carcasses, cuts, and viscera over, in the period 10 to 42 days of life. A completely randomized design was carried out, with four treatments and four repetitions. The experimental unit consisted of 16 male and female Cobb 500 chickens (a total of 256 birds) that were 10 to 42 days old. The treatments consisted of four diets with 0%, 7.5%, 15%, and 22.5% of cassava root meal (CRM) in three feeding programs. At 42 days old, four birds per unit were slaughtered and the carcass yield, main cuts, and edible viscera were evaluated. The inclusion of levels of 15% and 22.5% of CRM in the diet of broiler had a negative influence on weight gain, food consumption, and feed conversion in the initial period and in the overall growth of the birds. Carcass yield, cuts, and viscera were not influenced by the diet. Based on the results, it is recommended that a maximum of 7.5% of the cassava root bran may be used in the diet of broilers of the Cobb 500 strain, over 10 to 42 days, without compromising the zootechnical performance of the birds or the yield of edible carcasses, cuts, and viscera.

ABSTRACT Objective: Therefore, the purpose of the currently study was to analyze the expression of the STRO-1 stem cell marker and the marker related to Hsp25 differentiation and dental development during odontogenesis in rats. Methods: Eighteen-day Wistar rat embryos and 7-day-old animals were analyzed morphologically via Hematoxylin and Eosin (HE) staining and via immunohistochemical marking for Stro-1 and Hsp25 in 5uM serial sections. Results: In the HE morphological analysis in 18-day embryos, the stage of tooth development was in the cap phase, while in the 7-day old animals it was in the bell phase. Conclusion: The expression of STRO-1 in the embryos was not found in the region of the dental papilla or enamel organ, however, in the 7-day-old animals, STRO-1-positive cells were found in the region of the dental follicle and dental papilla. As for the Hsp25, this exhibited weak marking in the cap phase while in the bell phase, there was a reaction, mainly in the odontoblasts. The expressions in the site of these markers vary according to the stage of tooth development.

RESUMO Esta pesquisa filia-se aos postulados do Círculo de Bakhtin no que se refere ao dialogismo da linguagem, em especial, à responsividade ativa atribuída a todo discurso que se faz em resposta a outros. Situada no âmbito da Análise Dialógica do Discurso, propomos uma interface com alguns elementos da Gramática Discursivo-Funcional para a análise linguística dos enunciados. Nosso objetivo é avaliar como a atitude responsiva se instaura no discurso do Governo do Estado de São Paulo em relação a declarações do governo federal, de modo a construir uma política institucional em tempos de pandemia da covid-19. Por meio da análise de dois vídeos, constatamos que a atitude responsiva que o Governo de São Paulo procura demonstrar não configura, necessariamente, atitudes de responsabilidades perante os menos favorecidos, entretanto, alcança seu objetivo, que é contrapor o discurso do governo federal para orientar as atitudes da população no cenário pandêmico.

Published: November 2021

Abstract: The aim of this study was to evaluate changes in the physiological quality of soybean seeds throughout a storage period in two environments, and to evaluate how these changes are related to metabolites of the phenylpropanoid pathway. A completely randomized experimental design was used in a 4 × 8 factorial arrangement (storage periods × cultivars) with four replications. We used seeds from cultivars with contrasts in lignin content, color, and presence of anthocyanin in the seed coat, and isoflavone content in the seed. The seeds were kept for six months under cold and dry storage and in a non-controlled environment. Germination, first germination count, seedling emergence, and tetrazolium testing were performed on the seeds every two months. The physiological quality of the seeds declines during the storage period, with higher rates of decrease in the non-controlled environment. The metabolites of the phenylpropanoid pathway that were studied, especially lignin, affect seed storage potential. Cultivars with higher lignin content show greater storage potential, especially in a non-controlled environment.

Published: November 2021

Abstract: The aim of this study was to establish a methodology to determine physiological vigor in small and large seeds of Hymenaea courbaril L. non-scarified seeds and scarified by the electrical conductivity test and period of seed soaking in water aiming at maximum capacity of emergence and seedling vigor. The design was completely randomized, in a 2 x 2 x 5 factorial scheme (two classes of seed mass, non-scarified seeds and scarified and five periods of soaking in water), with 10 replicates of 10 seeds each. The variables evaluated were electrical conductivity (μS cm-1.g-1), emergence speed (index), seedling emergence (%) and mean time of emergence (days), obtained by means of daily counts until stabilization in the values. Maximum vigor of Hymenaea courbaril seedlings is obtained with large seeds subjected to scarification and soaked in water for six hours. Water content of 18.7% in large seeds of Hymenaea courbaril scarified promotes the production of 100% of vigorous seedlings. Small and large seeds of Hymenaea courbaril non-scarified seeds and scarified, soaked for six hours, had shorter mean time for seedling emergence. Water content of 20.6% in small seeds of Hymenaea courbaril scarified promotes 100% seedling emergence. The electrical conductivity test applied to Hymenaea courbaril seeds can be adopted to determine seed vigor, showing speed in the obtaining of results and ease of execution.

Furthermore, it can increase gross regional domestic product, employment opportunities, and opening up opportunities of other industrial sectors growth.
Biocontrol in practice in Canadian floricultural greenhouses
Authors: Singh Poonam , Nykolyshyn Tiffany
Published: November 2021

Abstract The environment inside Canadian prairie greenhouses differs from greenhouses built in other northern latitude locations in terms of lighting, temperature, humidity, and photoperiod. Since the performance of biocontrol agents depends upon several interactive environmental variables, their effectiveness to control pests in a particular crop growing under certain climatic conditions does not directly translate to another crop or location. So, we analyzed research trials assessing the efficacy and compatibility of various biocontrol agents (Amblyseius cucumeris, Amblyseius cucumeris, Phytoseiulus persimilis, Encarsia formosa, Aphidius colemani, Aphidius ervi, and Steinernema feltiae) on key pests (Western flower thrips, two-spotted spider mites, greenhouse whiteflies, and aphids) of spring bedding plants grown in a commercial floricultural greenhouse. Were analyzed several compatible combinations of biocontrol agents and observed a significant reduction in pest densities and plant damage symptoms as compared to untreated control plants. The results demonstrate that P. persimilis controlled two-spotted spider mites successfully in calibrachoa crop. The combination of Amblyseius cucumeris and S. feltiae resulted in significantly better control of Western flower thrips than the use of Amblyseius cucumeris alone in sweet potato vine plants. The application of E. formosa and Amblyseius cucumeris individually reduced greenhouse whiteflies on calibrachoa plants as compared to control, but their combination performed better resulting in a significantly lower number of whiteflies on plants. Another combination of Aphidius colemani and Aphidius ervi controlled green peach aphids and foxglove aphids effectively on the pansy crop. The biocontrol agents were effective for managing a variety of pests in a commercial greenhouse setting.

Published: November 2021

Abstract The lisianthus culture is demanded to produce cut flowers and pot vases, grown in a greenhouse using advanced techniques. The present study aimed to evaluate the pigments of different lisianthus cultivars in different photoselective shade nets. The cultivars Flare Deep Rose (pink), Echo Blue BL (purple) and Allemande White BI (white) were cultivated under light-diffusing polyethylene film cover and blue and red color photoselective nets with a shading capacity of 30%, in addition to the control treatment, without the use of the net. The results showed higher values of chlorophyll b and total in the red photoselective net, independent of the cultivar. Leaf colorimetry showed the most intense shade of green was from the cultivar Echo Blue BL. On the other hand, the control showed more intensity, with no significant difference in the leaf green intensity on the blue and red shade nets. In the petals, the cultivar Echo Blue BL showed a more intense blue shade in the red net, however low grade of anthocyanin than in the blue one. In the anthocyanin pigment, this cultivar had lower levels in the treatment of the red net. The results indicate that the use of photoselective shade nets in the culture of lisianthus changes the content of the pigments studied, in varying intensity, depending on the cultivar.

Abstract Vernalization, natural or artificial, is a physiological requirement of some plants to meet the need for low temperatures for its complete development to occur. The objective of this article is to describe a protocol of transforming a domestic refrigerator into a BOD (Biochemical Oxygen Demand) prototype aimed at vernalizing propagating materials statice crop. The first step is to install a temperature controller to maintain a constant temperature inside the refrigerator (10 °C). Thinking of seedling vernalization, it is still necessary to install a system of lights inside the refrigerator. The control of the time that the lights remain on inside the prototype is carried out by installing a Timer adjusted so that the lights remained on, uninterruptedly, for 10 hours. To test the effective ness of the prototype, an on-farm experiment was carried out with the statice (Limonium sinuatum L.) crop at 5 locations in Rio Grande do Sul, Brazil. The seedlings were vernalized at an internal temperature of 10 °C and photoperiod of 10 hours for 3 weeks. The duration of this experiment was 8 months and at the end of this observed that statice plants were correctly vernalized because the plants emitted flower stems and showed satisfactory development throughout the growing cycle. Therefore, that the adaptation of a domestic refrigerator as a BOD economically viable and easy mounting prototype is possible. Being an excellent alternative to small producers.

RESUMO O objetivo da pesquisa foi analisar a configuração da pós-graduação stricto sensu em Educação Física no Brasil a partir da compreensão de coordenadores e egressos de dois programas da área. Realizou-se uma entrevista semiestruturada com os sujeitos pesquisados. As informações foram discutidas à luz da teoria eliasiana. Evidenciou-se que a organização interna, a produção intelectual, o status acadêmico e a formação são elementos que influenciam essa configuração e que se firma uma polarização entre pesquisa e docência na formação em voga. É possível concluir que, os avanços que decorrem dessa dinâmica favorecem o fortalecimento da atividade científica da área e que a polarização identificada não favorece uma formação mais ampliada para os estudantes.
Comparação entre métodos de estimativa de evapotranspiração de referência no município de São José dos Ausentes (RS), Brasil

Published: November 2021

RESUMO A evapotranspiração de referência é uma componente muito importante do balanço hídrico e sua estimativa é essencial para execução de projetos agrícolas e ambientais, estudos de balanço hídrico, projetos e manejo de irrigação, modelagem de processos climatológicos e planejamento do gerenciamento dos recursos hídricos. O método de Penman-Monteith é considerado pela Food and Agriculture Organization of the United Nations como padrão para estimar a evapotranspiração de referência, contudo, dada a dificuldade de se obter um número grande de variáveis meteorológicas que são empregadas nesse método, tem-se utilizado vários outros métodos para estimar a evapotranspiração de referência.

RESUMO Os sistemas de recuperação de biogás contribuem para a mitigação de gases do efeito estufa, além de agregarem valor econômico ao processo de decomposição anaeróbia da matéria orgânica. O presente trabalho busca analisar os potenciais energéticos e a viabilidade econômica de implementação de um sistema de recuperação de biogás de aterro sanitário (cenário 1) ou de uma usina de digestão anaeróbia (cenário 2) para o Consórcio do Maciço de Baturité no estado do Ceará, Brasil. Para isso, foi estimada a projeção populacional, seguida da estimativa da produção de biogás pelo software LandGEM. Para o sistema de recuperação de biogás do aterro sanitário, foi obtida a potência ótima de 460 kW, com geração de energia máxima de 3.223.680 kWh/ano, enquanto, para a usina de digestão anaeróbia, foram obtidos valores de potência e energia de 252 kW e 1.986.754,86 kWh, respectivamente. De acordo com a análise econômica, ambos os projetos possuem inviabilidade de implementação, todavia o preço da unidade de energia gerada (kWh) é 42,42% maior para a usina de digestão anaeróbia em relação ao do sistema de recuperação de biogás do aterro sanitário. A metodologia aplicada pode ser utilizada para estudos preliminares em outros tipos de consórcio, contribuindo para melhores gerenciamento de resíduos e aproveitamento energético de sistemas de biogás no país.

Published: November 2021

RESUMO A urbanização conduz ao acréscimo de superfícies de baixa permeabilidade nas bacias hidrográficas, o que resulta em aumento no volume de água pluvial escoado superficialmente nos terrenos e, consequentemente, na ampliação de poluentes carreados aos cursos de água receptores, o que pode prejudicar a qualidade de suas águas. O objetivo principal da presente pesquisa foi analisar a variação da qualidade da água ao longo do dia em um córrego impactado por área urbana por meio do índice de qualidade das águas (IQACETESB) e dos parâmetros envolvidos no seu cálculo. A coleta de amostras foi realizada uma vez ao mês, durante o período de sete meses, nos seguintes horários: 8h, 14h e 19h. No geral, foram encontradas baixas concentrações de oxigênio dissolvido e altos teores de matéria orgânica e nutrientes no córrego avaliado. A amostragem em diferentes períodos do dia foi eficiente em relação ao entendimento dos processos antrópicos que acontecem na sub-bacia estudada (e.g., lançamento de esgoto doméstico in natura e aporte intenso de fósforo no período da manhã). Além disso, foi observada uma oscilação significativa no valor do IQACETESB entre os três períodos do dia, tal como em junho de 2018: 52 (manhã) e 23 (noite). Dessa forma, a avaliação do IQACETESB conduzida em apenas um horário do dia pode deixar passar informações essenciais para os gestores ambientais, resultando em uma visão errônea do problema.

ABSTRACT The presence of waterborne pathogens, when associated with the water supply system, poses risks to public health. This study investigated the occurrence of (oo)cysts of Cryptosporidium spp. and Giardia spp. in two Water Treatment Plants, with full-cycle technology, and assessed the microbiological risk to consumers’ health. The membrane filtration technique was employed to identify the protozoan load in 24 samples of raw and filtered water. Physicochemical and bacteriological parameters were also analyzed. The Quantitative Microbial Risk Assessment model was used to determine the risk of daily and annual infection associated with the ingestion of filtered water. A total of 66.67% of raw water samples were positive for Cryptosporidium; and 33.33%, for Giardia. The maximum concentrations of 200 (oo)cysts/L and 50 cysts/L were detected in the Cerrado stream (located in Sanclerlândia, state of Goiás, Brazil), due to the predominance of grazing areas and intense agricultural activity. Water Treatment Plants did not completely remove the protozoa and the retention efficiency was lower than that recommended by the United States Environmental Protection Agency, with average values of 1.27 log for cysts and 1.04 log for oocysts. The probability of annual infection by cysts (100%) was higher than that of oocysts (86.61 - 98.32%) as for consumption of filtered water, and in the dry season, there was a higher risk of infection, due to the low performance of the Water Treatment Plants and higher concentration of pathogens. According to the results, the continuous intake of filtered water above the warning level can cause infectious diseases in the supplied population.

Published: November 2021

Abstract Steel-concrete slim flooring system using precast concrete hollow core slabs and steel beam with web openings is an innovative construction system designed to combine the high bending resistance of both precast prestressed hollow core slabs and steel beam with web openings. This system can provide floor systems with a minimum constructional depth in comparison with ordinary composite floors. The aim of this study was to evaluate in an exploratory way the shear transferring mechanism between the steel beam with circular web opening and the precast hollow-concrete slab. The shear connection is formed by in-situ concrete passes through the web openings and infill the voids of the precast slabs. One push-out test was conducted to investigate the shear transferring mechanism of shear connection and the experimental results were compared to analytical methods. The shear resistance of the shear connection was predicted with good accurate by analytical methods.

Allogeneic hematopoietic stem cell transplantation (HSCT) is the treatment for many diseases, however can induce important complications such as Oral Mucositis (OM) and Graft-versus-Host Disease (GVHD). The neutrophil-lymphocyte ratio (NLR) is a peripheral biomarker of systemic inflammation and an independent prognostic factor in several inflammatory diseases. Objective: The aim of this study was to evaluate the association of NLR with OM and GVHD in patients undergoing allogeneic HSCT. Methods: Patients who underwent  allogeneic HSCT at the Bone Marrow Transplant Service at the Hospital de Clínicas Complex of the Federal University of Paraná were included in the study. Sociodemographic data and blood count were collected from patients' medical records. NLR was calculated and associated with OM and GVHD. Results: 45 patients were included in the study. NLR was considerably higher in patients who had OM and oral GVHD when compared to patients who did not present these conditions, nonetheless no statistically significant difference was observed. Conclusion: Although both OM and GVHD are associated with inflammatory response as well as to the immune system, it was not associated with NLR. A further investigation considering other variables related to the HSCT might find possible association as it could favor patients management and prevention.
Probabilistic long-term resilience of bridges under seismic and deterioration processes
Authors: Qian Jing , Dong You , Frangopol Dan M.
Published: November 2021

Accurate long-term risk and resilience assessments of bridges are of paramount importance to aid rational decision making under seismic hazards. Both earthquakes and structural deterioration exhibit time-varying features. It has been found that the occurrence of large earthquakes is dependent on time, due to energy accumulation, whereas the widely adopted homogeneous Poisson process assumes a time-independent hazard occurrence. Bridges can deteriorate over time due to environmental exposure, resulting in increased seismic vulnerability. The time-varying characteristics associated with earthquakes and deterioration, which have compound effects on structures, should thus be incorporated in long-term seismic risk and resilience assessments. An approach for assessing the long-term resilience of bridges incorporating the time-varying characteristics of earthquakes and deterioration is presented. The Brownian passage time model, capturing energy accumulation and release, is used to model the time-varying characteristics of earthquakes. Bridge seismic vulnerability is computed in a time-varying manner considering deterioration. Subsequently, long-term bridge resilience loss is computed by considering earthquakes and deterioration over the entire service life of the bridge. The proposed approach is illustrated on a highway bridge subjected to time-dependent seismic hazard and structural deterioration.
Pyrolysis of waste polyolefins and e-component to produce renewable green fuel over cadmium carbonate
Authors: Singh Man Vir , Kumar Sudesh
Published: November 2021

The interest and relevance of the present paper are in the current waste plastic valorisation scenario. The rapid depletion of fossil source carbon as crude oil and its ever-increasing costs have led to an intensive search for alternative fuels. An alternative or renewable green fuel (RGF) was obtained from waste low- and high-density polyethylene or polyolefins and computer body plastics through a pyrolysis process using cadmium carbonate (CdCO3) from 23 to 400°C. Five types of hydrocarbons were observed through two-dimensional gas chromatography and time-of-flight mass spectrometry (GC×GC-TOFMS): 7.621% paraffins, 53.668% branched/cyclic hydrocarbons, 14.083% aromatics, 0.327% phenanthrenes and 24.301% unclassified compounds. The research octane number of the RGF was 88.29. The bromine number of the RGF was 34.03%. The RGF was suitable for diesel engines and diesel furnaces without any upgrading. During the first, second and third pyrolysis experiments, 98, 95 and 100 g (wt%) waste granules with 2, 5 and 0 g (wt%) cadmium carbonate into RGFs were collected at 85, 89 and 80%; uncondensed gases were collected at 14.22, 10.15 and 19.52%; and the residue was collected at 0.78, 0.85 and 0.48%.
Molecular Sovereignty: Building a Blood Screening Test for the Brazilian Nation
Authors: Kameda Koichi
Published: November 2021

This article interrogates the relationship between the development of national diagnostic technologies and the exercise of sovereignty, by analysing a Brazilian project to produce a nucleic acid test (NAT) for the country’s blood screening programme. The concept of ‘molecular sovereignty’ is proposed to demonstrate that exercising sovereignty demands not only technological resources but also a sufficiently powerful and national imaginary to support local knowledge production as a means of advancing national healthcare priorities. First, this research article contextualises the political importance of blood safety for Brazil during its transition to democracy in the 1980s and the creation of its universal healthcare system. Then, it investigates how adopting the NAT led the state to invest in the production of a national technology. Third, the article unpacks the diagnostic test to consider how certain aspects of the project might ultimately strengthen the ability of global capital to cross national boundaries and create new markets. Lastly, it discusses how the project ended up creating a centralised and ‘closed’ system to avoid leaving the country vulnerable to the entry of global diagnostic companies. This case demonstrates how the molecularisation of blood, through the construction of a unified healthcare system driven by the constitutional right to health, can be deployed to construct imagined communities on the scale of a nation.
