Serial numbers are marks present on several day-to-day objects, created by manufacturers for purposes such as quality control, product tracking and to prevent counterfeiting. In the case of firearms, these characters can be obliterated or damaged by natural processes or intentionally by criminals to prevent positive identification of stolen property. One non-destructive method employed by crime laboratories for the restoration of obliterated characters is the magnetic particle method. The present work aims to study the synthesis and application of waste-made magnetic nanoparticles in the recovery of adulterated markings. A set of analytical-grade materials and metallic waste magnetic nanoparticles were synthesized for comparison purposes. Chemical characterization tests by X-ray fluorescence, morphological tests by scanning electron microscopy (SEM), and magnetization tests by vibrating sample magnetometer (VSM) were performed. The efficacy of the synthesized nanoparticles was tested on 1020 steel plates previously engraved and adulterated by sanding. Both homemade magnetic nanoparticles demonstrated superior performance compared to commercial magnetic particles. The application of homemade magnetic particles, especially using waste as the source of production, decreases the cost of the material and is environmentally friendly. The development of this material makes magnetic serial number restoration a better option for widespread use in forensic procedures. daytoday day objects control counterfeiting firearms property nondestructive non destructive wastemade made markings analyticalgrade analytical grade Xray X ray fluorescence SEM, SEM , (SEM) VSM (VSM performed 102 sanding particles production friendly procedures (SEM 10 1

Bredemeyera Willd. is a genus of the Polygalaceae family, occurring in Brazil. This research aims to evaluate the phytochemical and antifungal potential, in vitro and in silico, of Bredemeyera brevifolia extracts. The identification of fatty acids by gas chromatography-mass spectrometry and their quantification by gas chromatography-flame ionization detector showed that palmitic (36.55 mg g−1), margaric (3.66 mg g−1), linolelaidic (108.82 mg g−1), oleic (7.86 mg g−1), stearic (41.11 mg g−1), dihomo-γ-linolenic (85.48 mg g−1), and arachidic (209.00 mg g−1) acids are present in the hexane extract. From the chloroform extract, 1-hydroxy-3,7-dimethoxyxanthone was isolated and identified. The minimum inhibitory concentration assay with methanolic extract demonstrated antifungal activity against species of the genus Candida, Sporothrix, and Trichophyton for up to 96 h, with values ranging from 64-1024 μg mL−1. The in silico study with the chemical compounds of this species showed fungal inhibition potential of sterol-14-α-demethylase, highlighting 1-hydroxy-3,7-dimethoxyxanthone, which presented an affinity energy of -8.8 kcal mol−1, greater than that observed for fluconazole (−8.3 kcal mol−1). The fatty acids interacted with the active site of the enzyme but presented energies ≥ −7.4 kcal mol−1. Compounds isolated from this species have pharmacokinetic potential for the development of pharmaceutical formulations.

This study aimed to employ bibliometric methodologies to provide an overview of silver nanoparticles used as antimicrobial agents over the past decade. According to research conducted using the Scopus and Web of Science databases, a total of 2504 articles were published globally, of which 109 were from Brazilian institutions. Notably, approximately 70% of the leading article-producing countries are in Asia, with India emerging as the primary contributor with 1892 articles. Brazil ranked sixth in terms of publication volume, contributing 366 articles. Predominantly, the Southeastern region of Brazil exhibited the highest publication output, constituting 61% of the total, with the state of São Paulo playing a central role. Despite a gradual increase in the number of publications, most studies focused on synthesis methodologies, mainly producing aqueous silver nanoparticle solutions and their correlation with antimicrobial applications. The scarcity of publications addressing their efficacy in final commercialized products poses challenges for regulatory actions, quality control, and sanitary surveillance. Bibliometric studies are valuable tools for guiding future research efforts with significant potential impacts to foster a deeper understanding of this topic within the scientific community. decade databases 250 globally 10 institutions Notably 70 articleproducing article Asia 189 volume 36 Predominantly output 61 role applications actions control surveillance community 25 1 7 18 3 6 2

ABSTRACT Ornamental pepper plants have genetic variability, which can be accessed through morphological and molecular traits. Genotype selection to form the base population for breeding can be performed through the joint analysis of several types of data, providing greater selection accuracy. From this perspective, this study aimed to evaluate the diversity among pepper accessions based on analysis of phenotypic traits and molecular markers and to select the best ones to use as parents in breeding programs. The study was carried out at the Centro de Ciências Agrárias of the Universidade Federal da Paraíba, Paraíba, Brazil. Sixteen ornamental pepper genotypes were used and characterized for eight quantitative traits, nine qualitative traits, and 18 pairs of microsatellite primers. Simultaneous variable analyses were performed using Tocher’s clustering method, Ward’s clustering algorithm, and the dissimilarity matrix. The clustering methods were efficient in separating the genotypes, identifying genetic variability, and accuracy in the selection through the joint analysis of quantitative, qualitative, and molecular data. Different groups were formed among the genotypes by Tocher’s method (six groups) and Ward’s method (three groups). There is genetic variability among ornamental pepper genotypes considering the joint analysis of quantitative, qualitative, and molecular data. Qualitative traits are important in the identification of genetic divergence among ornamental pepper accessions. The UFPB genotypes 46, 134, 137, 443 and 449, the mini pepper Akamu, and the cultivar Calypso are indicated for selection and can be used to carry out crosses and continue the breeding program. data perspective programs Paraíba Brazil 1 primers Tochers Tocher s Wards Ward algorithm matrix six three groups. . 46 134 137 44 449 Akamu program 4 13

Food contamination is a public health problem, and the search for natural additives to increase food stability and safety is challenging. This research aimed to study nanoemulsions produced with coriander essential oil and kefiran, an exopolysaccharide extracted from kefir grains. The composition of coriander essential oil was evaluated, revealing linalool as the main component. An experimental design consisting of six trials was conducted. The NE2 formulation (0.5% kefiran and 1.5% coriander essential oil) exhibited smaller particle size, monodispersity, a lower centrifugal stability coefficient, and higher absolute zeta potential values (> 30 mV), indicating high electrical stability. Morphology, thermal stability, and toxicity tests were performed. The minimum bactericidal concentration was determined and applied to commercial cheese. Thermal stability tests demonstrated an increase in the stability of NE2 compared to its individual components, and it was also proven to be non-toxic. The concentration of 25% m v-1 was identified as the minimum bactericidal concentration and was applied to commercial cheese. problem challenging grains evaluated component conducted NE 0.5% 05 0 5 (0.5 15 1 1.5 size monodispersity coefficient > ( 3 mV, mV , mV) Morphology performed cheese components nontoxic. nontoxic non toxic. toxic non-toxic 25 v1 v v- 0.5 (0. 1. 2 0.

This paper presents an analytical multiresidue method for the quantification of 7 nitroimidazoles, 19 anthelmintics, 3 amphenicols, and 4 dyes in poultry, pork, beef, horse, shrimp, and fish samples by isotope dilution ultra-high performance liquid chromatography coupled with tandem mass spectrometry (UHPLC-MS/MS) in a single 6 min run. Samples were prepared using a modified quick, easy, cheap, effective, rugged and safe (QuEChERS)-type extraction with ethyl acetate and Na2SO4-NaCl (2:1), concentration into dimethyl sulfoxide (DMSO), and defatting by liquid-liquid extraction (LLE) with n-hexane. No clean-up using solid-phase extraction (SPE) cartridges or dispersive solid-phase extraction (DSPE) was necessary. The linearity ranges (in μg kg-1) were 0.10-0.60 for chloramphenicol, 0.50-3.0 for dyes, 1.5-9.0 for nitroimidazoles, and 5.0-30.0 for the other drugs. The limits of quantitation (LOQ) were established at the lowest calibration curve levels. Except for chloramphenicol in the horse matrix, analyte recovery and reproducibility were satisfactory (recovery (fREC): 75.0 to 116.6%; coefficient of variation (CV): 1.2 to 29.9%). For the unapproved substances and the substances with a maximum residue level (MRL), respectively, the decision limits (CCα) were 0.14-4.10 and 5.28-1003.60 μg kg-1, while the detection capabilities (CCβ) were 0.13-3.33 and 5.46-11.56 μg kg-1. nitroimidazoles 1 anthelmintics amphenicols poultry pork beef shrimp ultrahigh ultra high UHPLCMS/MS UHPLCMSMS UHPLC MS/MS MS (UHPLC-MS/MS run quick easy cheap effective QuEChERStype QuEChERS type Na2SO4NaCl NaSONaCl Na2SO4 NaCl Na SO 21, 21 2 , (2:1) DMSO, DMSO (DMSO) liquidliquid LLE (LLE nhexane. nhexane n hexane. hexane n-hexane cleanup clean up solidphase solid phase SPE (SPE DSPE (DSPE necessary kg1 kg kg-1 0.100.60 010060 0.10 0.60 0 10 60 0.10-0.6 0.503.0 05030 0.50 3.0 50 0.50-3. 1.59.0 1590 1.5 9.0 5 9 1.5-9. 5.030.0 50300 5.0 30.0 30 5.0-30. drugs LOQ (LOQ levels matrix fREC (fREC) 750 75 75. 116.6% 1166 116 CV (CV) 12 1. 29.9%. 299 29.9% . 29 29.9%) MRL, MRL (MRL) respectively CCα (CCα 0.144.10 014410 0.14 4.10 14 0.14-4.1 5.281003.60 528100360 5.28 1003.60 28 1003 5.28-1003.6 kg1, 1, CCβ (CCβ 0.133.33 013333 0.13 3.33 13 33 0.13-3.3 5.4611.56 5461156 5.46 11.56 46 11 56 5.46-11.5 kg1.

RESUMO O aporte de resíduos vegetais ao longo dos ciclos da cana-de-açúcar favorece o incremento de matéria orgânica e atividade de microrganismos no solo, especialmente nas camadas superficiais. A textura do solo também tem um efeito importante nos processos ecológicos e na qualidade do solo. Nesse sentido, o objetivo desta pesquisa foi avaliar atributos biológicos do solo em diferentes ciclos de cultivo de cana-de-açúcar sob colheita mecanizada, em um Latossolo da região de cerrado do Brasil Central. O estudo foi realizado em áreas comerciais de cultivo de cana-de-açúcar na safra 2018/2019, consideradas homogêneas em termos de condições edafoclimáticas, tendo como fonte de variação entre as áreas os ciclos de cultivo (C1: um ciclo de cultivo; C3: três ciclos de cultivo; C7: sete ciclos de cultivo) e uma área de vegetação de cerrado selecionada como referência. Foram determinadas variáveis microbiológicas nas camadas de 0-0,10 e 0,10-0,20 m. As variáveis relacionados à biomassa microbiana e textura foram submetidos à análise de componentes principais. Áreas com ciclos de cultivo de cana-de-açúcar mais longos apresentaram maior proporção de carbono da biomassa microbiana no carbono orgânico total nas camadas subterrâneas (quociente microbiano). O desempenho da comunidade microbiana do solo, expresso pelos indicadores carbono orgânico total e nitrogênio da biomassa microbiana foi associado à maior presença de argila e silte, ou seja, partículas de solo menores que 0,02 mm. canadeaçúcar cana açúcar superficiais sentido mecanizada Central 20182019 2018 2019 2018/2019 edafoclimáticas C1 C (C1 C3 C7 referência 00,10 0010 0 0,10 10 0-0,1 0,100,20 010020 0,20 20 0,10-0,2 m principais quociente microbiano. microbiano . microbiano) silte seja 002 02 0,0 mm 2018201 201 2018/201 (C 00 00,1 001 010 0,1 1 0-0, 100 0,100,2 01002 020 0,2 2 0,10-0, 0, 201820 2018/20 00, 01 0-0 0,100, 0100 0,10-0 20182 2018/2 0- 0,100 0,10- 2018/

ABSTRACT The contribution of plant residues throughout the sugarcane cycles favors the increase of organic matter and the activity of microorganisms in the soil, especially in the surface layers. Soil texture also has an important effect on ecological processes and soil quality. In this context, the objective of this study was to evaluate soil biological attributes in different sugarcane cultivation cycles under mechanized harvesting in an Oxisol in the Savanna region of Central Brazil. The study was conducted in commercial areas under sugarcane cultivation during the 2018/2019 season, which were considered homogeneous in terms of soil and climatic conditions, with the source of variation among the areas being the cultivation cycles (C1: one cultivation cycle; C3: three cultivation cycles; C7: seven cultivation cycles) and a savanna vegetation area selected as a reference. Microbiological variables were determined in two layers, 0-0.1 and 0.1-0.2 m. The variables related to microbial biomass and texture were subjected to principal component analysis. Areas with longer sugarcane cultivation cycles show higher proportion of microbial biomass carbon in the total organic carbon in subsurface layers (microbial quotient). The performance of the soil microbial community, as expressed by total organic carbon and microbial biomass nitrogen indicators, was associated with higher presence of clay and silt, i.e., soil particles smaller than 0.02 mm. quality context Brazil 20182019 2018 2019 2018/201 season conditions C1 C (C1 cycle C3 C7 reference 00.1 001 0 0.1 1 0-0. 0.10.2 0102 0.2 2 0.1-0. m analysis quotient. quotient . quotient) community indicators silt ie i e i.e. 002 02 0.0 mm 2018201 201 2018/20 (C 00 00. 01 0. 0-0 10 0.10. 010 0.1-0 i.e 201820 20 2018/2 0- 0.10 0.1- 20182 2018/

RESUMO A salinidade desencadeia uma série de efeitos nocivos na nutrição mineral das plantas, o que causa perda na produção. O objetivo deste estudo foi avaliar os efeitos do uso de água salobra com irrigação por gotejamento por pulso e contínua no acúmulo de nutrientes na cultura de amendoim (Arachis hypogaea). O delineamento experimental utilizado foi o de blocos casualizados sob esquema fatorial (6 × 2), constituído por seis níveis de condutividade elétrica da água de irrigação (CEa: 0,2; 1,6; 2,8; 4,0; 5,2 e 6,4 dS m-1) e dois tipos de manejo da irrigação (por pulsos e contínua) com quatro repetições. Após 63 dias de semeadura, o acúmulo e a exportação de macronutrientes, sódio e cloro foram quantificados. A irrigação por pulso mitigou os efeitos deletérios da salinidade sobre a cultura do amendoim e proporcionou um maior acúmulo de nutrientes pela cultura em relação a irrigação contínua. A ordem decrescente de acúmulo de nutrientes pelas plantas sob irrigação por pulso e contínua foi: K > N > Ca > Mg > P > S.

ABSTRACT High salinity levels trigger harmful effects on plant mineral nutrition, causing production losses. The objective of this study was to evaluate effects of using pulse or continuous drip irrigation with brackish water on the accumulation and exportation of nutrients in peanut (Arachis hypogaea) crops. A randomized block experimental design with four replications was used, in a 6×2 factorial arrangement consisting of six levels of electrical conductivity of irrigation water (ECw: 0.2, 1.6, 2.8, 4.0, 5.2, and 6.4 dS m-1) and two irrigation regimes (pulse and continuous). Accumulation and exportation of macronutrients, sodium, and chloride were quantified at 63 days after sowing. Pulse irrigation mitigated the harmful effects of high salinity levels on peanut crops and promoted greater nutrient accumulation by plants compared to continuous irrigation. The descending order of nutrient accumulation by plants under pulse and continuous irrigation was: K > N > Ca > Mg > P > S. Pulse irrigation is effective in mitigating the detrimental effects of using brackish water on peanut crops. nutrition losses Arachis hypogaea used 62 6 2 6× ECw (ECw 02 0 0.2 16 1 1.6 28 8 2.8 40 4 4.0 52 5 5.2 64 6. m1 m m-1 continuous. . continuous) macronutrients sodium sowing S 0. 1. 2. 4. 5. m-

RESUMO O potássio é um dos nutrientes mais importantes para o algodoeiro, sendo um elemento que participa de muitas funções fisiológicas na planta. Além disso, sua adequada disponibilidade favorece melhor desempenho produtivo à cultura. Logo, objetivou-se avaliar nesta pesquisa os componentes agronômicos em cultivares de algodão naturalmente colorido adubadas com doses de potássio no Semiárido brasileiro. Para isto, dois experimentos foram conduzidos na Fazenda Experimental Rafael Fernandes, localizada no município de Mossoró, RN, nos períodos de julho a novembro de 2019 e julho a novembro de 2021. O delineamento experimental foi o de blocos casualizados, arranjados em parcelas subdivididas, com quatro repetições. Nas parcelas, foram alocadas as doses de potássio (0, 60, 120, 180 e 240 kg ha-1 de K2O); e, nas subparcelas, as quatro cultivares de algodão naturalmente colorido (BRS Rubi, BRS Safira, BRS Verde e BRS Topázio). As cultivares de algodão colorido respondem à adubação potássica em função das condições edafoclimáticas as quais estão expostas. A cultivar BRS Topázio obteve maior produtividade e porcentagem de fibra nas duas safras de cultivo, destacando o seu potencial para a região. A dose de 240 kg ha-1 de K2O aumentou a produtividade do algodão colorido, em cultivo de segunda safra.

ABSTRACT Potassium is one of the most important nutrients for the cotton plant, being an element that participates in many physiological functions. In addition, its adequate availability favors better production performance of the crop. Therefore, the objective of this study was to evaluate the agronomic components in naturally colored cotton cultivars fertilized with potassium doses in the Brazilian semiarid region. For this, two experiments were conducted at Rafael Fernandes Experimental Farm, located in the municipality of Mossoró, RN, from July to November 2019 and July to November 2021. The experimental design was randomized blocks, arranged in split plots, with four repetitions. Potassium doses (0, 60, 120, 180, and 240 kg ha-1 of K2O) were allocated in the plants; and four naturally colored cotton cultivars (BRS Rubi, BRS Safira, BRS Verde, and BRS Topázio) were allocated in the subplots. Colored cotton cultivars respond to potassium fertilization depending on the edaphoclimatic conditions to which they are exposed. BRS Topázio cultivar had higher lint cotton yield and fiber percentage in both growing seasons, highlighting its potential for the region. The dose of 240 kg ha-1 of K2O increased the yield of colored cotton, in second crop cultivation. The cultivars BRS Safira, BRS Rubi, and BRS Verde were not very productive. plant functions addition Therefore region Farm Mossoró RN 201 2021 blocks plots repetitions 0, 0 (0 60 120 180 24 ha1 ha 1 ha- KO K O plants Rubi Safira subplots exposed seasons cultivation productive 20 202 ( 6 12 18 2

RESUMO Os coeficientes genéticos precisam ser calibrados para as cultivares mais representativas do mercado, portanto, é necessário adicionar novas cultivares a modelos como o SimulArroz. Portanto, o objetivo deste estudo foi calibrar e avaliar o modelo SimulArroz para duas novas cultivares de arroz irrigado. Os experimentos foram conduzidos no município de Goianira em Goiás durante quatro safras (2014/15, 2015/16, 2016/17, 2017/18) e no Rio Grande do Sul nos municípios de Alegrete (2015/16), Cachoeirinha (2015/16), Capão do Leão (2016/17, 2017/18), Santa Vitória do Palmar (2017/18) e Uruguaiana (2014/15, 2015/16). O delineamento utilizado foi o de blocos casualizados, com quatro repetições no Rio Grande do Sul e com parcelas de semeadura em Goianira.

ABSTRACT Given genetical coefficients need to be calibrated for the most important cultivars on the market, new cultivars must be added to models such as SimulArroz. Thus, the aim of this study was to calibrate and evaluate the SimulArroz model for two new irrigated rice cultivars. The experiments were conducted in the municipality of Goianira in Goiás state during four growing seasons (2014/15, 2015/16, 2016/17, 2017/18) and in Rio Grande do Sul state in the municipalities of Alegrete (2015/16), Cachoeirinha (2015/ 16), Capão do Leão (2016/17, 2017/18), Santa Vitória do Palmar (2017/18) and Uruguaiana (2014/15, 2015/16). A randomized block design was used, with four replicates in Rio Grande do Sul and sowing plots in Goianira. The BRS Catiana and BRS Pampa cultivars were used and the Haun stage (HS), phenology, shoot dry matter biomass and yield were evaluated. The root mean square error (RMSE) for above-ground dry matter ranged from 51.7 to 577 g m-2, and for yield, the normalized root mean square error (NRMSE) ranged from 24 to 32% and 22 to 35% for the potential and high technological levels, respectively. The SimulArroz model was able to satisfactorily predict the growth, development, and yield of the BRS Catiana and BRS Pampa cultivars, increasing their area of application, including the tropical region of Brazil. market Thus 2014/15, 201415 2014 15 (2014/15 201516 2015 16 2015/16 201617 2016 17 2016/17 2017/18 201718 2017 18 , (2015/16) 2015/ (2015 16, 16) (2016/17 2017/18, (2017/18 2015/16. . 2015/16) HS, HS (HS) phenology evaluated RMSE (RMSE aboveground above ground 517 51 7 51. 57 m2, m2 m 2, 2 m-2 NRMSE (NRMSE 32 35 levels respectively growth development application Brazil 2014/15 20141 201 1 (2014/1 20151 2015/1 20161 2016/1 2017/1 20171 (2015/16 (201 (2016/1 (2017/1 (HS 5 m- 3 2014/1 20 (2014/ 2016/ 2017/ (2015/1 (20 (2016/ (2017/ 2014/ (2014 (2 (2016 (2017 (

RESUMO A alface (Lactuca sativa) é a hortaliça folhosa de maior importância econômica no Brasil, sendo o tipo crespa a mais popular entre os produtores. Entretanto, em regiões de clima quente, a alface apresenta limitações de produção devido ao pendoamento precoce, exigindo o conhecimento do comportamento das cultivares disponíveis no mercado. Assim, o objetivo do presente estudo foi caracterizar o desempenho de cultivares de alface crespa quanto aos aspectos produtivos, fisiológicos e de qualidade pós-colheita, cultivadas em condições de cultivo hidropônico e alta temperatura. O ensaio foi conduzido em condição de casa de vegetação, sendo as plantas cultivadas em sistema hidropônico tipo DFT. A temperatura média durante o experimento foi de 30,33 °C. O delineamento experimental utilizado foi o inteiramente casualizado com nove tratamentos (Veneranda, Cristina, Olinda, Mônica, Cinderela, Grand Rapids, Itapuã Super, Crocantela e Simpson Black Seed) e quatro repetições. As cultivares foram analisadas quanto ao seu desempenho produtivo, fisiológico e de qualidade pós-colheita. As cultivares Olinda e Cristina apresentaram melhor desempenho nos parâmetros de crescimento, fisiológicos e pós-colheita. Entretanto, estas cultivares apresentaram características sensoriais distintas. Verificou-se que o pendoamento precoce afetou negativamente as trocas gasosas, a produção e a qualidade pós-colheita das cultivares de alface Veneranda, Mônica, Grand Rapids e Cinderela. Além disso, observou-se que o teor de pigmentos não foi determinante para a expressão do pendoamento. Portanto, este estudo recomenda o uso das cultivares Olinda e Cristina para o cultivo hidropônico em condições de alta temperatura.

ABSTRACT Lettuce (Lactuca sativa) is the most economically important leafy vegetable in Brazil, with the crisp type being the most popular among producers. However, in regions with hot climates, lettuce has production limitations due to bolting, requiring knowledge on the behavior of cultivars available on the market. Thus, the objective of the present study was to characterize the performance of crisp lettuce cultivars in terms of their productive, physiological, and postharvest quality aspects when grown under hydroponic cultivation and high temperature conditions. The assay was performed in a greenhouse and the plants were grown in a hydroponic system of DFT type. The average temperature during the experiment was 30.33 °C. The experimental design used was completely randomized with nine treatments (Veneranda, Cristina, Olinda, Mônica, Cinderela, Grand Rapids, Itapuã Super, Crocantela, and Simpson Black Seed), with four replications. The cultivars were analyzed in terms of their productive, physiological, and postharvest quality performances. The Olinda and Cristina cultivars showed the best performance in growth, physiological, and postharvest variables. However, the cultivars had distinct sensory characteristics. Bolting negatively affected gas exchange, production, and postharvest quality of lettuce cultivars Veneranda, Mônica, Grand Rapids, and Cinderela. In addition, it was observed that the pigment content was not determinant for the expression of bolting. Therefore, this study recommends the use of cultivars Olinda and Cristina for the hydroponic cultivation under high temperature conditions.

RESUMO A correlação canônica é usada para correlacionar grupos de variáveis distintas. O objetivo deste estudo foi utilizar análise de correlação canônica para avaliar a interação entre atributos de qualidade da água causadores de entupimento e o desempenho hidráulico de gotejadores não autocompensantes operando com diluições de efluente de aquicultura em água de poço. O experimento foi conduzido em delineamento inteiramente casualizado, em esquema de parcelas subsubdivididas, com três repetições, com cinco diluições nas parcelas (Diluição 1: 100% de efluente de aquicultura; Diluição 2: 75% de efluente de aquicultura + 25% de água de poço; Diluição 3 : 50% efluente de aquicultura + 50% água de poço; Diluição 4: 25% efluente de aquicultura + 75% água de poço; e Diluição 5: 100% água de poço), três emissores nas subparcelas (ST (1,6 L h-1) , SL (1,6 L h-1) e NJ (1,7 L h-1)), e três tempos de operação nas subsubparcelas (início do experimento, 80 e 160 horas, em que 0 horas de operação significa o início das avaliações). As análises estatísticas realizadas foram matriz de correlação e análise canônica. A análise de correlação canônica indicou que quando as concentrações dos atributos aumentam, o desempenho hidráulico dos gotejadores diminui. A interação desse grupo de atributos indica que o entupimento dos gotejadores que operam com as cinco diluições de efluente de aquicultura em água de poço ocorre pela ação combinada de agentes físicos, químicos e biológicos. O gotejador ST foi o menos sensível ao grupo de atributos de qualidade das diluições, enquanto o mais sensível foi o gotejador SL. distintas casualizado subsubdivididas repetições 1 100 2 75 25 50 4 5 poço, poço) 1,6 16 6 (1, h1 h h-1 1,7 17 7 h1, h-1)) 8 avaliações. avaliações . avaliações) aumentam diminui físicos biológicos 10 1, (1 h- (

ABSTRACT The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance of non-pressure compensating drippers operating with dilutions of aquaculture effluent in well water. The experiment was in a completely randomized design in a split-split-plot scheme with three replicates, with five dilutions in the plots (Dilution 1: 100% aquaculture effluent; Dilution 2: 75% aquaculture effluent + 25% well water; Dilution 3: 50% aquaculture effluent + 50% well water; Dilution 4: 25% aquaculture effluent + 75% well water; and Dilution 5: 100% well water), three emitters in the sub-plots (ST (1.6 L h-1), SL (1.6 L h-1) and NJ (1.7 L h-1)), and three operating times in the sub-subplots (0, 80 and 160 hours, in which 0 hours operating time means the start of evaluations). The statistical analyses performed were correlation matrix and canonical analysis. The canonical correlation analysis indicated that when the concentrations of attributes increase, the hydraulic performance of the drippers decreases. The interaction of this group of attributes indicates that the clogging of drippers operating with the five dilutions of aquaculture effluent in well water occurs by the combined action of physical, chemical, and biological agents. The ST dripper was the least sensitive to the group of quality attributes of the dilutions, whereas the most sensitive was the SL dripper. variables cloggingcausing causing nonpressure non pressure splitsplitplot split plot replicates 1 100 2 75 25 3 50 4 5 water, , water) subplots sub 1.6 16 6 (1. h1, h1 h h-1 1.7 17 7 h-1)) subsubplots 0, (0 8 evaluations. evaluations . evaluations) increase decreases physical chemical agents 10 1.

Objetivo: Este estudo avaliou a viabilidade da ULDCT em adultos na urgência com suspeita de pneumonia. Foram medidos a dose de radiação, o tempo entre a solicitação e os relatórios do exame, prescrições de antimicrobianos também foram correlacionadas. Métodos: Este estudo avaliou a viabilidade da ULDCT em adultos na urgência com suspeita de pneumonia. Foram medidas a dose de radiação, o tempo entre a solicitação e a disponibilização dos relatórios do exame, e também foram correlacionadas as prescrições de antimicrobianos. Entre outubro de 2017 e dezembro de 2018, incluímos prospectivamente adultos com suspeita de pneumonia adquirida na comunidade, sem diagnóstico definitivo por avaliação clínica. Os critérios de exclusão abrangeram condições clínicas que pudessem afetar a interpretação da imagem. Resultados: Foram incluídos 131 pacientes elegíveis (idade média de 43,5 anos; 57% homens) encaminhados para ULDCT. Dezoito (13,7%) foram excluídos. A dose média de radiação da ULDCT foi de 0,14 mSv. O intervalo de tempo entre a solicitação médica e o resultado da ULDCT foi de 43 minutos. Conclusão: A ULDCT mostrou-se viável para pacientes adultos com suspeita de pneumonia em contexto de urgência. Os relatórios foram disponibilizados num intervalo razoável e os resultados negativos foram associados a uma baixa taxa de prescrição de antibióticos.

Abstract Background: The role of ultra-low-dose chest CT (ULDCT) in the emergency department is unknown. Purpose: This study sought to examine feasibility of ULDCT in adults presenting to the emergency department for whom pneumonia was suspected. Radiation dose and time interval between medical request and ULDCT results were measured, antibiotic prescriptions were correlated. Methods: Between October 2017 and December 2018, we prospectively enrolled consecutive healthy adult patients in a single-center for whom community-acquired pneumonia was suspected and for whom no definitive diagnosis was possible by clinical judgment. Exclusion criteria comprised all chronic conditions that could impact severity and interpretation of image. Results: 131 eligible patients (mean age 43.5 years; 57% men) were enrolled to ULDCT. Eighteen (13.7%) patients were excluded. Average CT radiation dose was 0.14 mSv. Time interval between medical request and ultra-low-dose chest CT result was 43 minutes. Only 15.9% of patients with negative CT received antibiotics. Conclusion: Ultra-low-dose chest CT was feasible for almost all patients in a group of healthy adults presenting to the emergency department with suspected community-acquired pneumonia. Results were made available in a reasonable interval, and negative ones were associated with a low antibiotic prescription rate.

RESUMO O amendoim (Arachis hypogaea) é uma importante cultura agrícola no Brasil, considerada uma das mais importantes oleaginosas cultivadas. O uso de bactérias solubilizadoras de fertilizantes pode mitigar o estresse salino. O objetivo deste estudo foi avaliar as trocas gasosas, o crescimento e a eficiência do uso da água da cultura do amendoim irrigado com água salobra sob adubação fosfatada e inoculada com bactérias do gênero Bacillus sp. O delineamento experimental utilizado neste estudo foi inteiramente casualizado, em esquema fatorial 4 × 2 × 2, com 5 repetições, referente às formas de adubação (F1 - 0% fósforo, F2 - 50% fósforo, F3 - 100% fósforo e F4 - bovino biofertilizante), presença e ausência do inoculante e dois níveis de condutividade elétrica da água de irrigação (CEa - 0.3 e 4.0 dS m-1). As adubações com fertilizante orgânico (100% de biofertilizante) e mineral (50 e 100% de fósforo) associada a Bacillus sp. mitigou os danos causados pelo estresse salino e proporcionou maior eficiência no uso da água, índice de clorofila, concentração interna de CO2 e diâmetro do caule. O tratamento controle (sem adubação fosfatada e sem estresse salino) e a aplicação de Bacillus sp., promoveu maior desempenho na fotossíntese líquida, taxa de transpiração, condutância estomática e altura das plantas em plantas de amendoim.

ABSTRACT Peanut (Arachis hypogaea) is an important agricultural crop in Brazil, considered one of the most important oilseed crops cultivated. The use of fertilizer-solubilizing bacteria can mitigate salt stress. The objective of this study was to evaluate the gas exchange, growth, and water use efficiency of the peanut crop irrigated with brackish water under phosphate fertilization and inoculated with bacteria of the genus Bacillus sp. The experimental design used in this study was completely randomized, in a 4 × 2 × 2 factorial scheme, with 5 replicates, referring to the forms of fertilization (F1 - 0% phosphorus, F2 - 50% phosphorus, F3 - 100% phosphorus, and F4 - bovine biofertilizer), presence and absence of the inoculant and two levels of electrical conductivity of the irrigation water (ECw - 0.3 and 4.0 dS m-1). Fertilization with organic fertilizer (100% biofertilizer) and mineral fertilizer (50 and 100% phosphorus) associated with Bacillus sp. mitigated the damage caused by salt stress and promoted greater water use efficiency, chlorophyll index, internal CO2 concentration and stem diameter. The control treatment (without phosphate fertilization and without salt stress) and the application of Bacillus sp. promoted greater performance in net photosynthesis, transpiration rate, stomatal conductance, and plant height in peanut plants.

RESUMO O uso de Bacillus sp. atenua o estresse salino e aumenta o rendimento produtivo em plantas de soja. Neste contexto, o objetivo do presente estudo foi avaliar a produção da soja cultivada sob diferentes formas de adubação e estresse salino, inoculada com Bacillus sp. O experimento foi realizado na área experimental da Universidade da Integração Internacional da Lusofonia Afro-Brasileira (UNILAB), Redenção, Ceará. Utilizou-se um delineamento inteiramente casualizado em esquema fatorial 4 x 2 x 2, com cinco repetições, correspondente a quatro formas de adubação (F1 = 100% da recomendação de NPK; F2 = 50% da recomendação de NPK; F3 = 100% de biofertilizante bovino; F4 = organomineral - 50% de NPK + 50% de biofertilizante bovino), duas condutividades elétricas da água de irrigação (CEa - 0,3 e 4,0 dS m-1), com e sem inoculação de Bacillus sp. As formas de adubação orgânica com 100% da recomendação através de biofertilizante bovino, adubação organomineral - 50% mineral e 50% orgânica com biofertilizante bovino e 50% da recomendação de NPK, proporcionam maior desempenho produtivo da cultura soja irrigada com água de menor salinidade. A adubação organomineral - 50% mineral e 50% orgânica com biofertilizante bovino, foi mais eficiente para produção da cultura da soja, na ausência ou presença de Bacillus sp.

ABSTRACT The use of Bacillus sp. mitigates salt stress and increases the productive yield in soybean plants. In this context, the objective of the present study was to evaluate the production of soybean grown under different forms of fertilization and salt stress, inoculated with Bacillus sp. The experiment was performed in the experimental area of the University of International Integration of Afro-Brazilian Lusophony (UNILAB), Redenção, Ceará, Brazil. A completely randomized design was used in a 4 x 2 x 2 factorial scheme, with five replications, corresponding to four forms of fertilization (F1 = 100% of the NPK recommendation; F2 = 50% of the NPK recommendation; F3 = 100% bovine biofertilizer; F4 = organomineral fertilization - 50% NPK + 50% bovine biofertilizer), two electrical conductivities of the irrigation water (ECw - 0.3 and 4.0 dS m-1), with and without inoculation of Bacillus sp. The forms of fertilization organic with 100% of the recommendation through bovine biofertilizer, organomineral fertilization - 50% mineral and 50% organic with bovine biofertilizer, and 50% of the NPK recommendation promote greater productive performance of the soybean crop irrigated with water of lower salinity. Organomineral fertilization - 50% mineral and 50% organic with bovine biofertilizer was more efficient for soybean production, in the absence or presence of Bacillus sp. Salt stress negatively affected the production components of soybean crop under all forms of fertilization. sp plants context AfroBrazilian Afro Brazilian UNILAB, UNILAB , (UNILAB) Redenção Ceará Brazil scheme replications F1 F (F 100 50 biofertilizer) ECw 03 0 3 0. 40 4. m1, m1 m 1 m-1) salinity (UNILAB 10 5 m-1 m-
