Abstract This study investigated the effect of dolomitic lime incorporation on the microstructure and mechanical properties of metakaolin-based geopolymers activated by alkaline solution. Five geopolymer mixtures were prepared with the addition of 0.0%, 2.5%, 5.0%, 7.5%, and 10.0% dolomitic lime. The microstructure of the geopolymers was evaluated by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction analyses (XRD). The compressive strength of the mixtures ranged between 53.2 and 63.0 MPa after 28 days of ambient curing. SEM/EDS analyses showed that the main phases formed were the N-A-S-H gel together with the C-A-S-H and N-M-A-S-H gels in the mixtures with dolomitic lime. In summary, the results showed that the incorporation of dolomitic lime can significantly improve the microstructure and properties of geopolymers. metakaolinbased metakaolin based solution 00 0 0.0% 25 2 5 2.5% 50 5.0% 75 7 7.5% 100 10 10.0 SEM, SEM , (SEM) energydispersive energy dispersive Xray X ray EDS, EDS (EDS) XRD.

ABSTRACT The different stakeholder groups and their influence on value distribution have received increasing attention from organizations and academia. In the recent stakeholder literature, there has been a theoretical development on value distribution, considering the attributes of strategic importance and power; however, the literature still lacks empirical studies to analyze and understand the relationship. This paper examines the association between stakeholders’ power and strategic importance and the value distribution to them by publicly traded companies on the Toronto Stock Exchange (TSX). To obtain relevant information on companies’ treatment of their stakeholders, we analyzed the content of 104 prospectuses for the TSX IPO process from 2008 to 2019. The results reveal that power and strategic importance are relevant to the distribution of value to stakeholders and that the strategic importance of stakeholders has a more significant influence than their power.

ABSTRACT. Cotesia flavipes parasitizes Diatraea saccharalis, a pest that causes major losses to sugarcane production. The mass production of C. flavipes and its subsequent release onto sugarcane is one form of biological control of D. saccharalis. An essential factor for successfully fighting this pest is the development of host diets that can increase the efficiency of C. flavipes production. Palm oil contains saturated fatty acids, unsaturated fatty acids, and polyunsaturated linoleic acid. However, little is known about the effects of palm oil on C. flavipes production in the laboratory. Different concentrations of palm oil were added to the D. saccharalis diet and its nutritional indices were analyzed. Subsequently, the production and sex ratio of C. flavipes were determined. Our results indicated that the addition of higher palm oil concentrations to an artificial diet generated a high relative consumption rate (RCR) in D. saccharalis, and consequently a high relative metabolic rate (RMR), which resulted in a lower production of the parasitoid. In contrast, the lowest palm oil concentration in the artificial diet generated a low RMR and resulted in high-efficiency conversion of ingested food (ECI), enabling D. saccharalis to yield more C. flavipes. This suggests that palm oil influences the quantity of D. saccharalis ingested, which determines the number of C. flavipes that will be generated. In this study, supplementation of a D. saccharalis diet with 0.25% palm oil increased the production of C. flavipes. Therefore, this level of palm oil supplementation can aid in the production of C. flavipes on a laboratory-scale. Further research, including increasing the number of parasitoids, must be performed to mass-produce the augmentative releases of C. flavipes to manage D. saccharalis.

Abstract This study aimed to assess whether dentists correctly understand the benefit of a dental treatment when it is presented using absolute numbers or relative risk reduction (RRR). This parallel-group randomized controlled trial recruited dentists from 3 postgraduate courses in Rio de Janeiro, Brazil. Participants received, in sequentially numbered sealed opaque envelopes, the description of a hypothetical scenario of the benefit (avoidance of multiple tooth loss) of nonsurgical periodontal treatment without or with antibiotics. Treatment benefit was presented in 2 different formats: absolute numbers or RRR. Dentists were given 10 minutes to read the treatment scenario and answer 5 questions. The final sample for analysis included 101 dentists. When asked to estimate the number of patients out of 100 who would avoid multiple tooth loss without antibiotics, 17 dentists (33%) in the absolute numbers group and 12 (25%) in the RRR group provided the correct response (p = 0.39). Regarding treatment with antibiotics, 26 dentists (50%) in the absolute numbers group and 14 (29%) in the RRR group provided the correct response (p = 0.04). Only 16 dentists (31%) in the absolute numbers group and 12 (25%) in the RRR group gave correct answers for both questions (p = 0.51). Most dentists did not correctly understand the benefit of the treatment, irrespective of the format it was presented. Slightly more dentists correctly understood the benefit of the treatment when it was presented as absolute numbers than as RRR. .

Abstract Introduction The non-carious degradation of the dentin matrix is a natural process throughout life; however, when associated with the presence of excessive acidic substances, it leads to lesions in dental structures. Objective This study developed an experimental solution based on antioxidant polyphenols from the yellow passion fruit seed (Passiflora edulis) and assessed its preventive potential on eroded dentin. The experimental polyphenolic solution was obtained from passion fruit seeds through drying and cold pressing. Material and method Thirty samples of bovine cervical root dentin were acquired and randomized into three groups (n=10): G1 – distilled water; G2 – experimental solution of phenolic antioxidants from passion fruit; G3 – Commercial anti-erosion toothpaste. Erosive cycling and treatment were conducted over 3 days. Subsequently, non-contact 3D confocal microscopy was employed to measure volumetric (Sa) and linear (Ra) roughness, as well as erosive wear. A one-way ANOVA/Tukey test was performed (α=0.05). Result The G2 group had lower Ra and Sa values compared to the other groups and demonstrated the lowest erosive wear in µm compared to G1 and G3. Conclusion: The experimental solution based on antioxidant polyphenols from Passiflora edulis showed promising performance on eroded dentin in this investigation. Nevertheless, further research is required to establish its effectiveness and potential use in developing a new product. noncarious non carious life however substances structures pressing n=10 n10 n 10 (n=10) G water antierosion anti erosion toothpaste days Subsequently noncontact contact D (Sa (Ra roughness oneway one way ANOVATukey ANOVA Tukey α=0.05. α005 α α=0.05 . 0 05 (α=0.05) Conclusion investigation Nevertheless product n=1 n1 1 (n=10 α00 α=0.0 (α=0.05 n= (n=1 α0 α=0.

Low-cost adsorbents promote the valorization of locally sourced waste materials and are still a significant challenge for removing toxic metal ions from industrial effluents. In this sense, Castor (Ricinus communis L.) stalks (CS) were activated with an alkaline solution and tested as an adsorbent to remove nickel, copper, cadmium, and lead ions. A 24-1 factorial design was carried out and showed a correlation and influence of the variables, such as pH, adsorbent mass, agitation rate, and initial concentration in the adsorption process. The adsorbents in their natural, activated, and saturated states were characterized. After activation, X-ray diffraction results revealed a change from cellulose I to cellulose II. The X-ray fluorescence showed that the ion exchange adsorption mechanism occurred. For the kinetic adsorption studies, the equilibrium time was reached up to 15 min. Different isotherm models described the adsorption process, with the Sips model providing the best fit to the experimental data. Five cycles of sorption/desorption using 0.1 mol L-1 HCl elution were carried out with a minimal loss in sorption capacity and physical degradation. Nickel and copper ions exhibited the lowest desorption rates. Due to their efficiency, CS can be a promising and low-cost alternative for removing metal ions.

ABSTRACT Knowledge on the viability of the seeds is important in the management of the Germplasm Bank, as it allows monitoring the longevity and the need for regeneration of the accessions. The objective was to validate the efficiency of the Gomez-Campo methodology for seed conservation by evaluating physical dormancy and physiological quality of 11 Stylosanthes spp. accessions stored between seven and 13 years in the Forage Germplasm Bank of the State University of Feira de Santana (FGB-UEFS). One-hundred seed were used to determine moisture degree (%) and the viability with the descriptors: percentage of germination (G), germination speed index (GSI), synchronicity (Z) and average germination time (AGT). Sowing was done in plates moistened with water, arranged under controlled conditions (BOD chambers: at 20/30 °C and 12 hours/light) and in a completely randomized design in a 2 x 11 factorial scheme (scarified/non-scarified seeds and 11 accessions). After 14 days, it was observed that most of the accessesion presented high G (greater than 70%), GSI less than 2 seeds.day-1, Z with a mean value of 0,52 and AGT with a mean value of 2 days, characterizing a synchronous and rapid event.

ABSTRACT Salinity is considered an obstacle to the production system that limits the growth and yield of crops around the world. Therefore, it is essential to develop strategies to minimize the effects of salinity and increase yield, especially in the semi-arid region of the Northeast, which has limited water resources of good quality for irrigation. The objective was to evaluate the effects of applying paclobutrazol on zucchini crop under salt stress. The experiment was conducted in a greenhouse, in a randomized block experimental design, in a 2 × 5 factorial scheme, with two salinity levels of irrigation water (0.6 and 4.0 dS m-1) and five concentrations of paclobutrazol - PBZ (0; 2; 4; 6 and 8 g L-1), and with four repetitions. Application of 8 mg L-1 PBZ increases stem diameter in zucchini under irrigation of 4.0 dS m-1. Chlorophyll b and total chlorophyll contents increase with PBZ concentration of 4 mg L-1 and irrigation of 0.6 dS m-1. PBZ concentration of 4 mg L-1 increases the relative water content while reducing electrolyte leakage in zucchini under salinities of 4.0 and 0.6 dS m-1 respectively. Root, stem and leaf dry mass of zucchini increases when plants are irrigated with water of 0.6 dS m-1 and subjected to PBZ concentration of 8 mg L-1.

Abstract This research investigates the impact of using the h-index in the evaluation of scientific journals. Specifically, we aim to assess the use of these metrics to categorize a set of Brazilian journals from the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior Communication and Information area. The methodological approach involves an exploratory examination in which data from 20 scientific journals in the area were extracted from Google Scholar Metrics on July 4, 2022. The data collection also included recording authorship metadata, publication URL, periodical, year, and the total number of citations received. Data analysis was conducted through a calculation to measure each journal's self-citation, and one journal had its analysis highlighted. The results demonstrated that two journals stood out in terms of citation percentage, the volume of citations resulting from metadata errors, and the lack of structured metadata for source analysis. Therefore, despite the h-index being an interesting metric for evaluating journals in the Communication and Information area, it is considered that it could be complemented by qualitative evaluations capable of understanding the ethical challenges necessary to ensure a fair and adequate evaluation of academic research. hindex h index Specifically 2 4 2022 URL periodical year received s selfcitation, selfcitation self citation, self-citation highlighted percentage errors Therefore 202

Abstract Theoretically delimited to Linguistic Historiography, this article answers the following question: how was the presence of formalisms in linguistics in Brazil in the 1960s-1970s? Such question leads to the objectives of the analysis: (i) to characterize formalist linguistics in Brazilian linguistics; (ii) to delimit scientific guidelines of these formalisms; (iii) to identify social processes of institutionalization to aforesaid linguistics. The corpus consists of (a) journal articles, scientific bulletin texts, reviews, historical review books and chapters; (b) theses and dissertations; (c) manuals; (d) official documents; (e) testimonies, interviews. The material was selected and analyzed through three phases: 1st) heuristic: definition of periodization and selection/treatment of the corpus; 2nd) hermeneutic: establishment of ruling guidelines for historiographic analysis; 3rd) expository: presentation of results in a historiographic narrative. In the 1960s-1970s, Brazilian linguistics was largely a linguistics of domain of structures through the adoption of methodological instruments that identified systematic regularities (at different levels that highlighted the structural nature of languages) and supported rhetorics in defense of scientific positions. This historical characterization is defended in this article.

Resumen Delimitado teóricamente a la Historiografía Lingüística, este artículo contesta a la siguiente pregunta: ¿cómo fue la presencia de formalismos en la lingüística en Brasil durante las décadas de 1960-1970? Esta pregunta lleva a los objetivos del análisis: (i) caracterizar lingüísticas formalistas en la lingüística brasileña; (ii) delimitar directrices y alcances científicos de estos formalismos; (iii) identificar procesos sociales de institucionalización de dichas lingüísticas. El corpus está compuesto por (a) artículos de revistas, textos de boletines científicos, reseñas, libros y capítulos de reseña histórica; (b) tesis y disertaciones; (c) manuales; d) documentos oficiales; (e) testimonios, entrevistas. Este material se seleccionó y se analizó en tres fases: 1ª) heurística: definición de periodización y selección/tratamiento del corpus; 2ª) hermenéutica: establecimiento de directrices para el análisis; 3ª) expositiva: presentación de resultados en una narrativa historiográfica. En los años 1960-1970, la lingüística brasileña fue en gran medida una lingüística del dominio de las estructuras mediante la adopción de un instrumental metodológico que identificaba regularidades sistemáticas (en diferentes niveles que evidenciaban la naturaleza estructural de las lenguas) y ofreció apoyo para retóricas de defensa de posicionamientos científicos. Esta caracterización histórica se defiende en este artículo.

RESUMO O declínio-da-goiabeira é uma doença complexa, causada por Meloidogyne enterolobii em interação com Neocosmospora falciformis (sin. Fusarium solani). Por causa disso, a seleção de genótipos resistentes a M. enterolobii dentro do gênero Psidium é muito importante para o controle da doença. A detecção desta resistência em Psidium guajava seria, ainda, de maior impacto. Assim, este trabalho teve por objetivo avaliar a reação de P. guajava ‘Paluma’ a diferentes densidades de inóculo de M. enterolobii. Mudas de goiabeira foram inoculadas com 500, 1000, 5000, 10000 e 20000 ovos + juvenis de segundo estádio (J2) de M. enterolobii/planta. Aos 70 e aos 135 dias após a inoculação (DAI), foram avaliadas as massas de matérias frescas de raiz, de parte aérea e de matéria seca de parte aérea, bem como o comprimento de raiz, a altura da planta e o diâmetro do colo. Os números totais de ovos + J2 de M. enterolobii nos sistemas radiculares e os fatores de reprodução foram as variáveis nematológicas determinadas. A multiplicação do nematoide nas raízes não foi proporcional ao aumento da densidade de inóculo inicial e, por isso, nas menores densidades, encontraram-se as melhores respostas de multiplicação do nematoide na cultivar avaliada. Observou-se, então, que, conforme se aumentou a densidade de inóculo, obtiveram-se menores fatores de reprodução médios nas duas avaliações (70 e 135 DAI). declíniodagoiabeira declínio complexa sin. sin (sin solani. solani . solani) disso M seria ainda impacto Assim P ‘Paluma Paluma 500 1000 5000 2000 J (J2 enterolobiiplanta enterolobii/planta 7 13 DAI, DAI , (DAI) raiz colo determinadas isso encontraramse encontraram avaliada Observouse, Observouse Observou se, Observou-se então que obtiveramse obtiveram (7 DAI.

ABSTRACT Guava decline is a complex disease caused by the interaction between Meloidogyne enterolobii and Neocosmospora falciformis (Syn.: Fusarium solani). Thus, selecting M. enterolobii-resistant genotypes within the genus Psidium is essential for controlling this disease, and developing a resistant cultivar of Psidium guajava could significantly impact this issue. Thus, the objective of this study was to assess the response of the guava plants of the cultivar Paluma to different densities of M. enterolobii inoculum. Guava seedlings were inoculated with 500, 1,000, 5,000, 10,000, and 20,000 eggs + second-stage juveniles (J2) of M. enterolobii per plant. Root and shoot fresh weights, shoot dry weight, root length, plant height, and stem base diameter were evaluated at 70 and 135 days after inoculation (DAI). Total number of M. enterolobii eggs + J2 in the root system and nematode reproduction factor nematode were assessed. Nematode multiplication in roots was not proportional to increases in initial inoculum density; thus, the best plant responses to nematode multiplication in the evaluated cultivar were found for the lowest tested densities. The reproduction factor decreased as the inoculum density was increased, at both evaluations (70 and 135 DAI). Syn.

Abstract The genus Stylosanthes has economic importance in semi-arid regions and requires studies that reveal complex relationships between species involving different ploidies. The aim of this study was to cytogenetically investigate accessions of Stylosanthes identified as S. scabra, in order to properly identify the number, morphology, and pattern of distribution of heterochromatin, analyzing the karyological variability of these species. Accessions with 2n=40 and 2n=20 were identified, exhibiting semi-reticulate interphase nuclei, symmetric karyotype, varied morphology, with differences in average chromosomal size, and genome length. The analysis with the fluorochromes chromomycin (CMA) and 4’,6-diamidino-2-phenylindole (DAPI) allowed the visualization of two CMA+ blocks in the subterminal region of the short arm in all accessions, and DAPI+/CMA- bands in S. scabra accessions. This suggests that not only chromosomal rearrangements, but also changes in the composition of heterochromatin, may have occurred during the speciation of this genus, and that S. scabra may be undergoing chromosomal evolution based on the observed karyological differences. In addition to the ploidy level, the distribution pattern of CMA+ heterochromatin reinforces the separation between S. scabra and S. seabrana. Thus, this genus represents an interesting group of plants for further studies on the content and quantity of repetitive and non-repetitive DNA sequences. semiarid semi arid ploidies S number morphology 2n40 n 2n 40 2n=4 2n20 20 2n=2 semireticulate reticulate nuclei karyotype size length CMA (CMA 4,6diamidino2phenylindole 46diamidino2phenylindole diamidinophenylindole 4 ,6 diamidino 2 phenylindole 6 DAPI (DAPI DAPI+/CMA DAPICMA rearrangements level seabrana Thus nonrepetitive non sequences 2n4 2n= 2n2 6diamidino2phenylindole ,
