Resumo O uso de preservativos pode ser influenciado por aspectos psicológicos e socioculturais, que podem ser modulados por atitudes individuais. O objetivo foi propor uma versão em português brasileiro da Short-Form Condom Attitude Scale (Short-Form CAS), descrevendo os procedimentos de tradução, adaptação transcultural e avaliação das propriedades psicométricas em uma amostra de universitários. Trata-se de estudo transversal com estudantes matriculados na Universidade de São Paulo (USP), Campus Ribeirão Preto (n = 491; 61,2% feminino; média de idade: 22 anos; desvio-padrão: quatro anos). Foi realizada análise fatorial confirmatória. O modelo unifatorial com sete itens apresentou boa validade fatorial e confiabilidade, sugerindo ser a melhor solução fatorial para a Short-Form CAS. Há poucos estudos sobre os fatores comportamentais associados ao uso de preservativos em populações-chave, o que pode ser influenciado pela falta de instrumentos. A principal contribuição deste estudo foi propor uma versão simples e adaptada transculturalmente da Short-Form CAS com algumas propriedades psicométricas verificadas. Uma vez que o uso de preservativos é um componente do comportamento sexual de risco, a escala se apresenta como uma nova opção para futuros estudos na população brasileira. socioculturais individuais ShortForm Short Form CAS, , CAS) tradução universitários Tratase Trata USP, USP (USP) n 491 612 61 2 61,2 feminino idade anos desviopadrão desvio padrão desvio-padrão anos. . anos) confirmatória confiabilidade populaçõeschave, populaçõeschave populações chave, chave populações-chave instrumentos verificadas risco brasileira (USP 49 6 61, 4

Abstract The condom use can be influenced by psychological and sociocultural aspects, which can be modulated by individual’s attitudes. The aim was to propose a Brazilian Portuguese version of the Short-Form Condom Attitude Scale (Short-Form CAS), describing all procedures of translation, transcultural adaptation, and psychometric properties evaluation when applied to undergraduate students. A cross sectional study was conducted among students enrolled at University of São Paulo (USP), Campus Ribeirão Preto (n = 491; 61.2% female; average age: 22 years; standard deviation: four years). Confirmatory factor analysis was performed. A one-factor model with seven items exhibited good factorial validity and reliability, suggesting to be a better factorial solution of the Short-Form CAS in the sample. Few studies have been carried out on the behavioral factors associated with condom use in key populations, which can be exacerbated by a lack of appropriate scales. Therefore, the main contribution of the present study was to propose a simplified and transculturally adapted version of the Short-form CAS with some psychometric properties verified. Since the use of condoms is a component of the study of sexual risk behavior, this scale might be an option to be applied in various Brazilian population segments for this purpose. aspects individuals individual s attitudes ShortForm Short Form CAS, , CAS) translation adaptation USP, USP (USP) n 491 612 61 2 61.2 female age years deviation years. . years) performed onefactor one reliability sample populations scales Therefore Shortform form verified behavior purpose (USP 49 6 61. 4

Abstract Introduction: Chronic kidney disease is usually asymptomatic, and its diagnosis depends on laboratory tests, with emphasis on serum creatinine and proteinuria. Objective: To assess knowledge on the role of serum creatinine as a biomarker of kidney function in a sample of the Brazilian population. Method: Cross-sectional observational study conducted in São Paulo (SP, Brazil), in which a random adult population was interviewed. Results: A total of 1138 subjects were interviewed, with a median age of 36 years old (27–52); 55.1% were female. Regarding the “creatinine” biomarker, 40.6% stated they had never performed such a test. When asked about their knowledge on the usefulness of this exam, only 19.6% knew its function. The other responses were “I don’t know” (71.6%), evaluating heart function (0.9%) and liver function (7.8%). Of those who reported they had already taken a creatinine test, only 29.4% correctly identified the role of creatinine. When dividing the groups into “knows” and “does not know” the function of creatinine, a statistically significant difference (p < 0.05) was observed regarding level of education, female sex, being a healthcare student/worker, having ever measured creatinine, knowing someone with kidney disease and older age. In the multivariate analysis, the main variable related to knowing the creatinine role was having previously taken the test (OR 5.16; 95% CI 3.16–8.43, p < 0.001). Conclusion: There is a significant lack of knowledge about creatinine and its use in checkups. The results indicate that greater efforts are needed from healthcare professionals to raise awareness on the role of serum creatinine.

Resumo Introdução: A doença renal crônica costuma ser assintomática e seu diagnóstico depende da realização de exames laboratoriais, com destaque para a creatinina sérica e pesquisa de proteinúria. Objetivo: Avaliar em uma amostra da população brasileira o conhecimento sobre o papel da creatinina sérica como marcador de função renal. Método: Estudo observacional transversal realizado na cidade de São Paulo (SP, Brasil), em que foi entrevistada uma população adulta aleatória. Resultados: Foram entrevistados 1138 indivíduos, com idade mediana de 36 anos (27–52); 55,1% do sexo feminino. Com relação ao marcador “creatinina”, 40,6% afirmaram que nunca realizaram tal dosagem. Quando questionados quanto ao conhecimento sobre a utilidade desse exame, somente 19,6% sabiam a sua função. As outras respostas foram “não sei” (71,6%), avaliar o funcionamento do coração (0,9%) e fígado (7,8%). Dos que afirmaram já terem realizado o exame de creatinina, somente 29,4% acertaram a função da creatinina. Ao dividir os grupos em “sabe” e “não sabe” a função da creatinina, percebeu-se diferença estatisticamente significante (p < 0,05) em relação ao grau de escolaridade, sexo feminino, ser aluno/trabalhador da saúde, ter dosado creatinina alguma vez, conhecer alguém com doença renal e maior idade. Na análise multivariada, a principal variável relacionada com conhecer a função da creatinina foi ter realizado o exame anteriormente (OR 5,16; IC 95% 3,16–8,43, p < 0,001). Conclusão: Há grande desconhecimento sobre a creatinina e seu uso em check-ups. Os resultados indicam que é necessário maior esforço por parte dos profissionais de saúde para divulgar o papel da creatinina sérica.

Abstract The flotation mechanism of galena with xanthate as the collector is generally explained based on the mixed potential of the pulp, in which an anodic electron transfer reaction from the collector to the mineral is combined with an O2 cathodic reduction. Sodium sulphide, often used as a mineral activator, strongly influences the pulp's mixed potential, and depending on the dosage applied, it can become a galena depressor reagent. In this way, the current study assesses galena flotability in the absence of collector, as well as in the presence of the collector potassium amyl xanthate (PAX) and sodium sulphide. The effect of an extremely cathodic potential was also studied through the addition of hydrogen peroxide. In addition, the effect of different stages in the oxidation of the galena surface on the flotability was investigated. Moreover, the zeta potential was measured and contact angle (wettability) tests were carried out. The contact angle measurements were taken for a distilled water, PAX solution and for a mixture of PAX and sodium sulphide solution on the oxidized and non-oxidized surface of galena. All the results showed that galena could be floated in all the PAX concentrations tested. It was observed that a moderate oxidation in the galena surface may contribute to an improvement of its flotation with PAX. However, extremely anodic and cathodic potentials cause flotability close to zero. The zeta potential results showed that sodium sulphide affected the interaction between PAX and galena. The measurements of the contact angle corroborated the results obtained in the microflotation tests. pulp O reduction activator pulps s applied reagent way (PAX peroxide investigated Moreover wettability (wettability out water nonoxidized non tested However zero

Abstract Background: Methotrexate (MTX) is an alternative treatment for patients with moderate/severe atopic dermatitis (AD). Objective: The authors evaluated the effect of MTX on the cutaneous expression of cytokines and chemokines that are involved in the inflammatory response in adult AD patients who received treatment with methotrexate for 24 weeks. Methods: The authors conducted a prospective single-institution cohort study with 12 adults with moderate/severe AD who received oral MTX (15 mg/wk for 24 wks) and 10 non-atopic matched controls. The comparison was made of skin biopsies of lesional and non-lesional skin, pre- and post MTX treatment. The authors analyzed mean epidermal thickness and expression of IL-31, IL-31RA, OSMR, TSLP, Ki67, IL-4 mRNA, IL-6, IL-10, TNF-α, IFN-γ, TARC, and CCL-22. Results: There was a reduction in mean epidermal thickness (p = 0.021), an increase in IL-31RA expression (immunohistochemistry) in the epidermis (p = 0.016) and a decrease in IL-31 gene expression (p = 0.019) on lesional AD skin post-MTX treatment. No significant changes in the cutaneous expression of the other evaluated markers were identified. Study limitations: Small sample size and limited length of follow-up. Conclusions: Treatment with MTX in adults with moderate/severe AD reduced epidermal hyperplasia and changed the cutaneous expression of inflammatory cytokines and receptors that are mainly related to pruritus, including IL-31 and IL-31RA.

ABSTRACT: This study evaluated the effect of dietary supplementation with glutamine and glutamic acid (Gln+Glu) on performance, intestinal morphometry, and carcass characteristics of broiler quails. Eight hundred birds were used, distributed in an entirely randomized design with 20 birds per experimental unit, and given five treatments (0.0; 0.2; 0.4; 0.6; and 0.8% Gln+Glu supplementation) with eight replicates. At 1-21 days of age, lower (P < 0.05) feed intake at 0.6 and 0.8% Gln+Glu supplementation and lower weight gain at 0.8% Gln+Glu supplementation compared to the control treatment were observed. By regression analysis, excluding the control treatment, there was an increasing linear effect (P < 0.05) for feed intake at 22 to 42 days of age. For intestinal morphometry, Gln+Glu supplementation only favored the villus development of the ileum (P < 0.05), giving it greater height at 0.2, 0.6, and 0.8% supplementation. Carcass characteristics, cuts, and edible viscera of the birds at 42 days were not affected (P > 0.05) by Gln+Glu supplementation levels. Thus, the glutamine and glutamic acid supplementation affected the performance and intestinal morphology of 21-d-old quails, decreasing feed intake and weight gain associated with the improvement of ileum morphology; conversely, performance and carcass characteristics at 42 days were not affected by amino acid supplementation.

RESUMO: Objetivou-se avaliar o efeito da suplementação dietética de glutamina e ácido glutâmico (Gln+Glu) sobre o desempenho, a morfometria intestinal e as características de carcaça de codornas de corte. Foram utilizadas 800 aves, distribuídas em delineamento inteiramente casualizado, com cinco tratamentos (0,0; 0,2; 0,4; 0,6 e 0,8% de suplementação de Gln+Glu) e oito repetições com 20 aves por unidade experimental. Na fase de um a 21 dias, constatou-se menor (P < 0,05) consumo de ração aos níveis de 0,6 e 0,8% de Gln+Glu e menor ganho de peso ao nível 0,8% de Gln+Glu em comparação ao tratamento controle; e, pela análise de regressão, excluindo-se o tratamento controle, houve efeito linear crescente (P < 0,05) para consumo de ração na fase 22 a 42 dias de idade. Para morfometria intestinal, a suplementação de Gln+Glu apenas favoreceu o desenvolvimento vilos do íleo (P < 0,05), conferindo-lhe maior altura aos níveis de 0,2; 0,6 e 0,8% de suplementação. As características de carcaça, cortes e vísceras comestíveis das aves aos 42 dias não foram afetadas (P > 0,05) pelos níveis de suplementação de Gln+Glu. Assim, a suplementação de glutamina e ácido glutâmico influenciou o desempenho e a morfometria intestinal de codornas de corte aos 21 dias de idade, promovendo redução do consumo de ração e do ganho, associado ao aumento morfométrico do íleo; por outro lado, o desempenho das aves e as suas características de carcaça aos 42 dias não foram afetados pela suplementação dos aminoácidos.

ABSTRACT Background: Microscopic colitis (MC) is a chronic inflammatory bowel disease causing non-bloody diarrhea, and several cases are undiagnosed as a hidden cause of chronic diarrhea. Objective: We aimed to report the symptoms, delay diagnosis and the treatment of MC in a case series. Methods: All patients were treated at a Gastroenterology reference office from May 2022 to June 2023. Personal history including preexisting disorders, use of medications and smoking habits were collected. The delay between the onset of symptoms and the correct diagnosis was informed. All patients consented to use budesonide MMX (Corament®) off label. Results: During the study period, six Caucasoid patients were diagnosed with MC, five females and one male, between the ages of 65 and 74. All patients had comorbities and were taking multiple prescription drugs. Laboratory findings showed negative serology for celiac disease for all patients, normal levels of albumin and vitamin B12. The delay between the symptoms and the MC diagnosis varied from 2 months to 6 years. All patients had a previous diagnosis of irritable bowel syndrome. All patients were in complete clinical remission during the treatment and referred no side effects of the drug. Conclusion: Older females using high-risk medications are suggestive of MC. Preventing delay in the diagnosis of MC is crucial to improvement in patients´ quality of life. Budesonide MMX appears to be effective, safe and well-tolerated.

Objetivo: Esse estudo visou relatar os sintomas, qual o atraso diagnóstico e o tratamento da CM em uma série de casos. Métodos: Todos os pacientes foram atendidos em um consultório de referência em Gastroenterologia no período de maio de 2022 a junho de 2023. Foram coletados antecedentes pessoais, incluindo distúrbios preexistentes, uso de medicamentos e tabagismo. Foi buscado o período entre o início dos sintomas e o diagnóstico correto. Todos os pacientes consentiram em usar budesonida MMX (Corament®) off label. Resultados: Durante o período do estudo, seis pacientes caucasóides foram diagnosticados com CM, cinco mulheres e um homem, com idades entre 65 e 74 anos. Todos os pacientes apresentavam comorbidades e faziam uso de vários medicamentos prescritos. Os achados laboratoriais mostraram sorologia negativa para doença celíaca em todos os pacientes, níveis normais de albumina e vitamina B12. O atraso entre os sintomas e o diagnóstico de CM variou de 2 meses a 6 anos. Todos os pacientes tinham diagnóstico prévio de síndrome do intestino irritável. Todos os pacientes apresentaram remissão clínica completa durante o tratamento e não referiram efeitos colaterais da droga. Conclusão: As mulheres mais velhas que usam medicamentos de alto risco são sugestivas de CM. Evitar o atraso no diagnóstico de CM é fundamental para melhorar a qualidade de vida dos pacientes.

ABSTRACT. Conservation practices such as no-tillage are necessary to maintain, and/or improve agricultural soil quality. However, straw formation and maintenance in tropical regions is a limiting factor to adopting this system. In this sense, this research aimed to study the effect of cover crops on straw formation, soil quality indicators, and cowpea yield under no-tillage in the Amazon savanna. Two experiments were carried out in consecutive years, on a Latossolo Amarelo. The treatments consisted of the straw of cover crops in a single (S) and intercrop (I) system, as follows: Urochloa brizantha (UBS), Pennisetum glaucum (PGS), Crotalaria juncea (CJS), Canavalia ensiformis (CES), Mucuna aterrima (MAS), U. brizantha and C. juncea (UBCJI), U. brizantha and C. ensiformis (UBCEI), P. glaucum and C. juncea (PGCJI), P. glaucum and C. ensiformis (PGCEI), and spontaneous vegetation (SV). Cowpea was cultivated after desiccation of the cover crops. Most of the straw favored soil particle aggregation, except for C. juncea and SV, which negatively influenced this variable. Basal soil respiration, organic carbon content, potassium, base saturation, geometric mean diameter, macroaggregates, and macroporosity at layer of 0-0.10 m were the most sensitive indicators for improving soil quality in a savanna environment.

Abstract A checklist of recent and fossil fishes of the Order Characiformes is presented herein and believed to be complete through 2022. A total of 47 collaborators checked and provided information about their taxa of expertise. The list is arranged in alphabetical order by family and then genus and includes all available synonyms. From a total of 3,087 species group names and 527 genus group names, 2,334 species are currently treated as valid, and assigned to 301 genera and 24 families. This total includes 25 species known only from the fossil record, of which 21 are assigned to eight extant families and four are Incertae sedis in Characiformes, but does not include five species based on fossil which were wrongly treated in Characiformes. The status of 79 nominal species remains unresolved. When there are two competing hypotheses about the validity of a name, one of them is chosen and the alternate interpretation is provided in the remark section of that name. Distributional summaries are presented as numbers that correspond to areas for which there is a record of occurrence of the species. A list of unavailable names is provided at the end since some of those names may need additional research to certify their status. 2022 4 expertise synonyms 3087 3 087 3,08 52 2334 2 334 2,33 valid 30 7 unresolved name 202 308 08 3,0 5 233 33 2,3 20 0 3, 23 2,

ABSTRACT: This trial evaluated the production performance, gastrointestinal nematode infection (GIN), and selected blood analytes, in Corriedale lambs during the finishing phase in an integrated crop-livestock system (ICLS) with 2 stocking rates. Fifty-two Corriedale lambs were divided into 4 groups: a semi confinement system with a low stocking rate (T1) for 70 days; a semi confinement system with a high stocking rate (T2) for 70 days; confinement for 28 days, followed by semi confinement with a low stocking rate (T3) for 42 days; and confinement for 28 days, followed by semi confinement with a high stocking rate (T4) for 42 days. Body weight, dry matter intake, blood collection, and faecal analysis of nematode eggs were performed for each animal. The stocking rates did not influence body weight gain for the semiconfined lambs (T1 and T2) or for the confined/semiconfined lambs (T3 and T4). All treatments had lower EPG counts at the end of the experimental period. The nematode genera identified during the experiment trial were Haemonchus and Trichostrongylus. There were no significant differences (P > 0.05) for packed cell volume, total plasma protein, and eosinophil means between treatments. These results suggested that the confinement followed by semi confinement in an ICLS, was an option for lamb production during the finishing phase which could be useful in reducing GIN without affecting the production performance.

RESUMO: O objetivo deste experimento foi avaliar o desempenho produtivo, infecção por nematódeos gastrointestinais (GIN) e variáveis sanguíneas selecionadas, em cordeiras Corriedale durante a fase de terminação em sistema integrado lavoura-pecuária (ICLS) com duas taxas de lotação. O experimento utilizou 52 cordeiras Corriedale divididas em quatro grupos: sistema de semiconfinamento com baixa taxa de lotação por área (T1) por 70 dias; sistema de semiconfinamento com alta lotação por área (T2) por 70 dias; confinamento por 28 dias, seguido de semiconfinamento com baixa lotação por área (T3) por 42 dias; e confinamento por 28 dias, seguido de semiconfinamento com alta lotação por área (T4) por 42 dias. Peso corporal, ingestão de matéria seca, coleta de sangue e análise fecal para ovos de nematódeos foram avaliados para cada animal. As taxas de lotação não influenciaram no ganho de peso dos cordeiros semiconfinados (T1 e T2) ou nos confinados/semiconfinados (T3 e T4). Todos os tratamentos apresentaram contagens menores de EPG no final do período experimental. Os gêneros de nematódeos identificados durante o experimento foram Haemonchus e Trichostrongylus. Não houve diferença significativa (P > 0.05) para hematócrito, proteína plasmática total e média de eosinófilos entre os tratamentos. Esses resultados sugerem que o confinamento seguido de semiconfinamento em ICLS pode ser uma opção para a produção de cordeiras na fase de terminação e pode ser útil para a redução da GIN sem afetar o desempenho da produção.

Abstract Brazil has emerged as the world's largest producer of annatto seeds (Bixa orellana L.). Fortunately, the increase in national production has been accompanied by an improvement in the quality of this raw material. Annatto is a typical crop of small producers who usually use their empirical knowledge to evaluate the quality of the crop. Thefore, the visual observation of the color of annatto seeds has been considered a quality standard by many producers. To evaluate the scientific evidence, the present study evaluated annatto seeds from 51 accessions of the germplasm bank of the Agronomic Institute (Instituto Agronômico de Campinas - IAC) to determine a possible correlation between the pigment’s contents and the color of annatto seeds as well as the influence of humidity on this correlation. The correlations between the concentrations of pigments, humidity, lipids, and color (L*, a*, b*) were also evaluated. The color was evaluated using a colorimeter with measurements of the CIE L*, a*, b* scale. Only the correlation between the variables moisture and lipids was considered strong through the simple correlation, while the variables bixin content and coordinate a* presented a significant correlation while eliminating the effect of moisture (partial correlation). Thus, a correlation between the red color and the bixin concentration of annatto seeds was observed even though it was a weak correlation. In turn, the color difference (ΔEab) between the samples with higher and lower bixin contents was only 1.44. This difference indicates that large variations in the bixin concentrations may lead to small color changes in the annatto seeds, impairing the use of this criterion for quality control of these seeds. worlds world s Bixa L..

Resumo O Brasil tem se firmado como o maior produtor mundial de sementes de urucum (Bixa orellana L.). Felizmente, o aumento da produção nacional tem sido acompanhado por uma melhoria da qualidade dessa matéria-prima. O urucum é uma cultura típica de pequenos produtores, que em geral usa seu conhecimento empírico para avaliar a qualidade do material que está produzindo. A observação visual da cor das sementes de urucum tem sido considerada padrão de qualidade por muitos produtores. Para avaliar as evidências científicas, o presente estudo avaliou amostras de sementes de urucum de 51 acessos do banco de germoplasma do Instituto Agronômico de Campinas (IAC), para determinar se existe correlação entre as concentrações de pigmentos com a cor das sementes e a influência da umidade nessa correlação. Foram avaliadas também as correlações entre as concentrações de pigmentos, umidade, lipídios e a cor (L*, a*, b*). Para a avaliação da cor, utilizamos um colorímetro com a medida da cor pelo sistema CIE L*, a*, b*. Apenas a correlação simples entre as variáveis Umidade e Lipídios foi considerada forte, pela classificação usada neste estudo. Quando se remove o efeito da Umidade (correlação parcial), apenas as variáveis bixina e a* apresentaram correlação significativa, considerada fraca pela classificação utilizada. Portanto, mesmo considerada fraca, há uma correspondência entre a cor vermelha das sementes de urucum com a concentração de bixina das amostras estudadas. Contudo, a diferença da cor (ΔEab) entre as amostras com maior e menor teor de bixina foi de apenas 1,44. Essa diferença indica que grandes variações nas concentrações de bixina nas sementes de urucum podem levar a pequenas variações de cor, dificultando o uso desse critério para o controle de qualidade desses grãos.

ABSTRACT Hematopoietic stem cell transplant (HSCT) recipients are at -increased risk for severe COVID-19. The aim of this study was to evaluate the burden of COVID-19 in a cohort of HSCT recipients. This retrospective study evaluated a cohort of adult hospitalized HSCT recipients diagnosed with COVID-19 in two large hospitals in São Paulo, Brazil post-HSCT, from January 2020 to June 2022. The primary outcome was all-cause mortality. Of 49 cases, 63.2% were male with a median age of 47 years. Allogeneic-HSCT (51.2%) and autologous-HSCT (48.9%) patients were included. The median time from HSCT to COVID-19 diagnosis was 398 days (IQR: 1211-134), with 22 (44.8%) cases occurring within 12 months of transplantation. Most cases occurred during the first year of the pandemic, in non-vaccinated patients (n=35; 71.4%). Most patients developed severe (24.4%) or critical (40.8%) disease; 67.3% received some medication for COVID-19, primarily corticosteroids (53.0%). The probable invasive aspergillosis prevalence was 10.2%. All-cause mortality was 40.8%, 51.4% in non-vaccinated patients and 14.2% in patients who received at least one dose of the vaccine. In the multiple regression analyses, the variables mechanical ventilation (OR: 101.01; 95% CI: 8.205 – 1,242.93; p = 0.003) and chest CT involvement at diagnosis ≥50% (OR: 26.61; 95% CI: 1.06 – 664.26; p = 0.04) remained associated with all-cause mortality. Thus, HSCT recipients with COVID-19 experienced high mortality, highlighting the need for full vaccination and infection prevention measures. (HSCT increased COVID19.

Abstract The transport capacity of the slurry pipelines is related to the internal roughness of the pipe. Thus, the application of corrosion protection methods is of fundamental importance, both in the operational phase and in times of temporary shutdown. In addition, corrosion also affects the service life of the duct. The studied pipeline was hibernated with nitrogen using the ABNT NBR 15280-2 standard as a reference and remained hibernated for 3.5 years. Chemical, mineralogical, and microstructural analyses were carried out on samples of materials removed from the pipeline interior during the hibernation period. The most striking phase found was magnetite, with botrioidal morphology, formed by the oxidation of steel in the pipeline. After reactivation, the pipeline was inspected by smart pigs with ultrasound and MFL technologies. It was found that the corroded regions are more concentrated in the initial kilometers of the sections, where important depths of corrosion were also observed, as well as higher rates of corrosion and erosion, which show the influence of the operational phase in the development of the pipeline corrosive process and wear. Thus, the application of the nitrogen hibernation process in long-distance pipelines proved to be feasible for long periods of time. However, improvements are suggested in this article to make the process more robust. pipe Thus importance shutdown addition duct 152802 15280 2 15280- 35 3 5 3. years Chemical mineralogical period magnetite morphology reactivation technologies sections observed erosion wear longdistance distance time However robust 1528 152 15 1

ABSTRACT. Tomato is a demanding crop in terms of handling, mainly because irrigation has a strong influence on fruit production and quality. Salinity changes the absorption, transport, assimilation, and distribution of nutrients in the plant. In general, such effects are analyzed using statistical tests. However, fuzzy models allow simulations between points that are not verified in agricultural experimentation. Currently, systems with artificial intelligence have excelled in the field of applied sciences, particularly fuzzy systems applied to mathematical modeling. The objective of this research was to use fuzzy modeling to analyze the biometric variables during the development of hybrid tomatoes under two different conditions: the first concerning different water tensions in the soil and the second concerning different salinity doses in irrigation. To this end, two models were developed based on an experiment carried out at São Paulo State University (UNESP), School of Agriculture, Botucatu, São Paulo State, Brazil. Both models sought to estimate the values of biometric variables of the tomato crop. Thus, two models were developed: Model 1 regarded water tensions and days after sowing (DAS), while Model 2 featured salinity and DAS. Fuzzy models provided results that verified the effects of irrigation and salinity layers. Two Fuzzy Rule-Based Systems (FRBS), an input processor with two variables, a set of linguistic rules defined from statistical procedures with percentiles, the Mamdani fuzzy inference method, and the center of gravity method to defuzzification were elaborated for this purpose. The range between −25 and −10 kPa (for Model 1) and between 0.08 and 3 dS m−1 (for Model 2) provided the development within the ideal parameters for the complete development of the plant cycle. The use of fuzzy logic has shown effectiveness in evaluating the development of tomato crops, thus showing potential for use in agricultural sciences. Moreover, the created fuzzy models showed the same characteristics of the experiment, allowing their use as an automatic technique to estimate ideal parameters for the complete development of the plant cycle. The development of applications (software) that provide the results generated by the artificial intelligence models of the present study is the aim of future research.
