Fruits of Schinus terebinthifolia Raddi were investigated. A fast and efficient method for the simultaneous determination of 11 polyphenolic substances by high performance liquid chromatography-diode array detector (HPLC-DAD) was applied. Limits of quantification ranged between 0.78 and 3.14 mg L-1. High concentrations of kaempferol were found. An exploratory evaluation was performed using principal component analysis (PCA) for fruit origin differentiation. Total phenolic content (TPC) ranged from 274 to 517 mg GAE 100 g-1; total flavonoid content (TFC) ranged from 101 to 283 mg QE 100 g-1. In vitro analyses showed that antioxidant capacity with 2,2-diphenyl-1-picrylhydrazyl (DPPH) ranged from 1.7 to 7 µM DPPH 100 g-1. The bacteriostatic and bactericidal effect were also evaluated against: Bacillus subtilis, B. cereus, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella choleraesuis, Candida albicans and C. glabrata, using broth microdilution assay. It can be inferred that S. terebinthifolia Raddi fruit has the potential to act as an ally in the search for new alternatives in the action against pathogens, and it can be used as a potential natural antioxidant and antimicrobial agent. Metals (Cu, Fe, Mg, Mn and Zn) were also determined by flame atomic absorption spectrometry (FAAS), with emphasis on high concentrations of Mg, Zn and Fe. investigated 1 chromatographydiode chromatography diode HPLCDAD HPLC DAD (HPLC-DAD applied 078 0 78 0.7 314 3 14 3.1 L1.

The species Oryza sativa (rice) and Musa cavendishii (banana) are sources of cellulose-rich waste biomass in the Amazon region, Tocantins State. This research investigates the nanoscale production of cellulose through the interactions between three choline amino acid ionic liquids Ch[AA]IL and the respective fibers by pretreatment. To this end, the synthesis of three ILs was carried out: choline arginate Ch[Arg], choline glycinate Ch[Gly] and choline lysinate Ch[Lys], characterized by Fourier transform infrared spectroscopy (FTIR). The samples resulting from the pretreatment were analyzed by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). It was possible to infer from the SEM micrographs that Ch[Arg] caused greater fiber breakage than the other ILs. The TEM analyses identified fibers up to 16 nm in diameter. Positive effects were observed in the diffractograms, although no crystallinity was obtained in the pretreated samples. Thermogravimetry curves showed that the fibers treated with Ch[Arg] showed higher thermal stability. rice (rice banana (banana celluloserich rich region State ChAAIL Ch AA IL end out ChArg, ChArg Arg , ChGly Gly Ch[Gly ChLys, ChLys Lys Ch[Lys] FTIR.

In silico and in vitro tests can reveal promising anti-leishmania activity for natural products and their derivatives. The aim of this study was to investigate in silico the pharmacological activities of potential new chalcones and their leishmanicidal potential in vitro. The in silico study was carried out using the PASS, MolPredictX and Molegro Virtual Docker 6.0 programs. Antiparasitic activity was assessed in axenic promastigote and amastigote forms of Leishmania braziliensis. The cytotoxicity tests used the J77G8 cell line. The chalcones exhibited 50% cytotoxic concentration values (CC50) values > 50 μM. Chalcone 4 (named FERAI) presented the best activity with concentration for 50% of promastigotes and intracellular parasites forms (EC50) of 9.75 ± 1.7 and 10.13 ± 1.7 μM for promastigote and amastigote, respectively. Reactive oxygen species (ROS) testing presented increased ROS levels in the parasite at the FERAI concentrations of 10 μM (56.33%), 20 μM (61.76%) and 30 μM (67.13%). Molecular docking revealed interactions (binding energy) between FERAI and the enzymes UDP-glycosyl pyrophosphorylase (-56.8384), dihydroorotate-dehydrogenase (-132.276) and trypanothione-reductase (-151.281). Our results demonstrated the anti-leishmanial activity of chalcones, especially FERAI, with a noted raising of ROS levels in the parasite.

Cupuaçu (Theobroma grandiflorum Schum.) is an Amazonian fruit rich in antioxidants potential due to its phenolic compounds. Its seeds produce cupulate, a chocolate-like product, and the residue remains rich in biocompounds. This study aimed to optimize and compare microwave-assisted (MAE) and high pressure/temperature extraction (HPTE) of polyphenolic and flavonoid compounds from cupuaçu seed by-products. A Box-Behnken 33 factorial design assessed the influence of extraction time, solid/liquid ratio, and ethanol concentration. Responses included total polyphenol content, total flavonoid content, and anti-radical power via the ABTS (2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid) method. In optimum conditions, MAE had the highest total polyphenol content and HPTE for flavonoids. Optimal conditions for both methods were 65% (m/v) ethanol concentration, 45 min extraction time, and 0.03 g mL−1 solid/liquid ratio. MAE and HPTE achieved greater recovery of (−)-epicatechin and (−)-epigallocatechin-3-gallate compared to percolation. Both techniques proved viable for recovering polyphenols from cupuaçu seed by-products, in less time and with less solvent. Thus, cupuaçu by-products can be a sustainable and functional food source, with MAE and HPTE providing high yields and quality extracts rich in polyphenols. Theobroma Schum.

The present work aims to extract and test cashew nut peel oil as a natural antioxidant in the oxidative stabilization of biodiesel. Therefore, determinations of the ideal time of Soxhlet and thermal extractions, Fourier transform infrared spectroscopy (FTIR) analyses, and evaluation of the oxidative stability by Rancimat method were carried out. FTIR analyses revealed that the 3rd cycle of extraction was sufficient to extract all the oil, with an average yield of 30.0%. For the thermal extraction of the laboratory technical cashew nut peel oil, the best extraction, based on statistical analysis, was 60 min, yielding 20.0%. The FTIR analysis of the extracted cashew nut peel oil showed characteristic peaks of phenolic groups and organic acids, showing differences in the intensities of the absorption bands. The oxidative stability showed induction period of 8 h 40 min for the hydraulic press extraction, 10 h 35 min for the Soxhlet extraction, and 10 h 65 min for the industrial technical extraction of the cashew nut peel oil. All values were below the 12-h limit established by the National Agency for Petroleum, Natural Gas and Biofuels (ANP). The technical cashew nut peel oil extracted in the laboratory presented an induction period of 11 h 12 min, close to that recommended by ANP, proving to be a promising natural antioxidant. Cardanol presented satisfactory results with 25 h 22 min, double that suggested by ANP. Thus, cashew nut peel oil showed important and promising results as a natural antioxidant for biodiesel. biodiesel Therefore extractions (FTIR out rd 300 30 0 30.0% 6 200 20 20.0% acids bands 4 1 3 12h Petroleum ANP .

ABSTRACT The consumption of atmospheric carbon dioxide by weathering buffers the greenhouse effect on Earth on a geological timescale. This mechanism is called the silicate carbon sink (SCS). Saprolite represents part of the weathering front of the Earth’s mantle, but historically, it has not received much attention from geoscientists. On a global scale, Brazil is the largest contributor to the SCS and the fourth largest contributor to the number of saprolite publications. In this study, Brazilian scientific production on the subject from 1990 to 2022 was assessed, considering publications indexed in the Web of Science, SciELO and Scopus databases. One hundred-eighty scientific articles were retrieved. In the last decade, seven articles were published per year. Over the 32 years under consideration, the number of articles on saprolite has increased. Most of the studies were concentrated in the southeastern region of Brazil, where the state of Minas Gerais led in terms of the number of publications (28.49%). The main areas in which the articles were published were related to ecology, Earth, and marine; however, they were cited by several others, including the areas of health and politics. A comparison of the number of publications per basin and the size of the SCS showed that there were fewer studies from the Amazon Basin than from the Paraná Basin. In conclusion, the geographical frontier for the study of saprolite in the Brazilian territory is the Amazon River Basin, and the methodological frontier is related to fluid/gas dynamics and the role of microbes in weathering at depth. timescale SCS. .

RESUMO O consumo de dióxido de carbono atmosférico pelo intemperismo tampona o efeito estufa na Terra em escala de tempo geológica. Esse mecanismo é chamado de sumidouro de carbono de silicato (SCS). Saprolito representa parte da frente de intemperismo do manto terrestre, mas historicamente não recebeu muita atenção dos geocientistas. Em escala global, o Brasil é o maior contribuinte para o SCS e o quarto maior contribuinte em número de publicações sobre saprolito. Neste estudo, a produção científica brasileira sobre o assunto de 1990 a 2022 foi avaliada, considerando publicações indexadas nas bases de dados Web of Science, SciELO e Scopus. Foram recuperados cento e oitenta artigos científicos. Na última década, sete artigos foram publicados por ano. Ao longo dos 32 anos considerados, o número de artigos sobre saprolito aumentou. A maioria dos estudos foi concentrada na região sudeste do Brasil, onde o estado de Minas Gerais liderou em termos de número de publicações (28,49%). As principais áreas em que os artigos foram publicados estavam relacionadas à ecologia, Terra e marinha; no entanto, foram citados por várias outras, incluindo as áreas de saúde e política. Uma comparação do número de publicações por bacia e o tamanho do SCS mostrou que havia menos estudos da Bacia Amazônica do que da Bacia do Paraná. Em conclusão, a fronteira geográfica para o estudo do saprolito no território brasileiro é a Bacia do Rio Amazonas, e a fronteira metodológica está relacionada à dinâmica de fluídos/gases e ao papel dos micróbios no intemperismo em profundidade. geológica SCS. .

ABSTRACT Struvite (NH4MgPO4∙6H2O) is a slow-release fertilizer obtained through phosphorus and/or nitrogen recovery from wastewaters, usually by adding magnesium salts. In this sense, the aim was to evaluate the viability of replacing commercial magnesium sources with alternative ones in the struvite precipitation process regarding ammonium and phosphate removal and precipitated crystal quantification and characterization. Experiments were conducted on a bench scale in a completely randomized design at pH 9.5 by precipitation of synthetic wastewater solution with four magnesium sources: MgCl2∙6H2O, MgSO4∙7H2O, MgO, and magnesite (MgCO3). After pre-acidification, derived solutions from low-cost alternative sources of magnesium removed above 55 and 90% of ammonium nitrogen and phosphate in solution, respectively, and reached around 10 g L-1 of precipitated crystals. Results proximity obtained with solutions derived from commercial sources of magnesium (46ꟷ56% of ammonium nitrogen removal, 97% of phosphate removal, and more than 6 g L-1 of precipitate formed) indicated that alternative reagents could easily substitute commercial ones if submitted to the previous digestion process, making magnesium available in solution. Qualitative analysis by X-ray diffraction confirmed the presence of both struvite and newberyite in most precipitates.

RESUMO A estruvita (NH4MgPO4∙6H2O) é um fertilizante de liberação lenta obtido através da recuperação de fósforo e/ou nitrogênio de águas residuais geralmente pela adição de sais de magnésio. Neste sentido, objetivou-se avaliar a viabilidade da substituição de fontes comerciais de magnésio por fontes alternativas no processo de precipitação de estruvita, em termos de remoção de amônio e fosfato, e quantificação e caracterização do cristal precipitado. Os experimentos foram conduzidos em escala de bancada sob delineamento inteiramente casualizado a pH 9,5 através da precipitação de uma solução de efluente sintético com quatro diferentes fontes de magnésio: MgCl2∙6H2O, MgSO4∙7H2O, MgO e magnesita (MgCO3). Após pré-acidificação, soluções derivadas de fontes alternativas de baixo custo de magnésio removeram acima de 55 e 90% de nitrogênio amoniacal e fosfato em solução, respectivamente, e alcançaram por volta de 10 g L-1 de cristais precipitados. A proximidade dos resultados obtidos com soluções derivadas de fontes comerciais de magnésio (46ꟷ56% de remoção de nitrogênio amoniacal, 97% de remoção de fosfato, e mais de 6 g L-1 de precipitado formado) indicou que reagentes alternativos puderam facilmente substituir os comerciais se submetidos ao prévio processo de digestão, a fim de tornar o magnésio disponível em solução. A análise qualitativa por difratometria de raios-X confirmou a presença de estruvita e newberyita na maioria dos precipitados.

ABSTRACT The introduction of 2,4-D-tolerant soybeans (ENLIST®) offers a new potential for herbicide application. Therefore, the present study aimed to (a) evaluate the effect of combinations of post-emergent herbicides on the control of Conyza spp. and (b) assess the selectivity of the post-emergent herbicide association in soybeans, ensuring effective application without compromising the health of the crop. A field experiment with 2,4-D-tolerant soybeans utilized a randomized complete block design with 14 treatments across four replications. Treatments included various combinations of 2,4-D with glyphosate, chlorimuron-ethyl, cloransulam-methyl, imazethapyr, bentazon, and imazamox. These were applied either as a single treatment or sequentially 15 days after treatment (DAT) using glufosinate-ammonium alongside two controls without herbicide application. The results showed less than 15% control across all treatments. At 21 DAT, only the treatments applied sequentially showed significant control, with effectiveness exceeding 80% against Conyza spp. In contrast, the single applications of the herbicide combinations with 2,4-D were ineffective for post-emergence control of Conyza spp. 2,4Dtolerant 24Dtolerant Dtolerant 2,4 D tolerant 2 4 ENLIST® ENLIST (ENLIST® Therefore (a postemergent post emergent spp b (b crop 1 replications 2,4D 24D glyphosate chlorimuronethyl, chlorimuronethyl chlorimuron ethyl, ethyl chlorimuron-ethyl cloransulammethyl, cloransulammethyl cloransulam methyl, methyl cloransulam-methyl imazethapyr bentazon imazamox DAT (DAT glufosinateammonium glufosinate ammonium 80 contrast postemergence emergence 4Dtolerant 24 2, (ENLIST 4D 8

RESUMO A introdução da soja tolerante a 2,4-D (ENLIST®) oferece um novo potencial para a aplicação de herbicidas. Dessa forma, o presente trabalho teve como objetivo: (a) avaliar o efeito das combinações de herbicidas pós-emergentes no controle de Conyza spp., e (b) a seletividade da associação de herbicidas pós-emergentes em soja, garantindo uma aplicação eficaz sem comprometer a saúde da cultura. Um experimento de campo com soja tolerante ao 2,4-D utilizou um delineamento experimental de blocos casualizados, com 14 tratamentos em quatro repetições. Os tratamentos incluíram várias combinações de 2,4-D com glifosato, chlorimuron, cloransulam, imazethapyr, bentazona e imazamox. Estes foram aplicados como um único tratamento ou sequencialmente 15 dias após o tratamento (DAT) usando glufosinato de amônio, juntamente com dois controles sem aplicação de herbicida. Os resultados mostraram menos de 15% de fitotoxicidade em todos os tratamentos. Aos 21 DAT, apenas os tratamentos aplicados sequencialmente mostraram controle significativo, com eficácia superior a 80% contra Conyza spp. Em contraste, as aplicações únicas das combinações de herbicidas com 2,4-D foram ineficazes para o controle pós-emergência de Conyza spp. 2,4D 24D D 2,4 2 4 ENLIST® ENLIST (ENLIST® forma objetivo (a pósemergentes pós emergentes spp b (b cultura casualizados 1 repetições glifosato chlorimuron cloransulam imazethapyr imazamox DAT (DAT amônio herbicida significativo 80 contraste pósemergência emergência 4D 24 2, (ENLIST 8

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.

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) stands for being the most serious epidemic (so far) of the 21st century. However, only a few computational studies have investigated the molecular mechanisms underlying the neutralization of the spike protein by antibodies of different classes. Hence, bioinformatic methods were employed to unravel the factors contributing to the remarkable neutralization capacity exhibited by specific antibodies. Initially, crystallographic structures of IgA monomeric / dimeric, IgG, and IgM antibodies binding with the receptor-binding domain region of the SARS-CoV-2 spike protein were retrieved. Subsequently, rigid molecular docking and molecular dynamic simulations were performed over 100 ns with explicit water solvation. Lastly, an energy decomposition was conducted to estimate the binding affinity using the last frames from molecular dynamics. The results revealed a higher binding affinity for both monomeric and dimeric forms of IgA antibodies against the spike protein. Additionally, a greater number of hydrogen bonds were observed during their interaction with the spike protein, as well as greater structural instability along the time and especially a more thermodynamically favorable interaction affinity.

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

ABSTRACT Chinch bugs [Blissus pulchellus Montandon (Hemiptera: Blissidae)] suck the phloem from susceptible forage grasses, injecting toxins that destroy plant vessels and compromise the flow of water and nutrients, leading to plant death. Thus, the aim of this study was to assess eight forage grasses for antixenosis resistance to B. pulchellus and compare the anatomical characteristics of leaf sheath tissue from resistant and susceptible species/cultivars. Experiments were conducted in a laboratory and greenhouse, using choice and no-choice tests with the following forage grasses: Urochloa ruziziensis, U. humidicola, U. brizantha ‘Piatã’, U. brizantha ‘Paiaguás’, U. brizantha ‘Marandu’, Panicum maximum ‘Mombaça’, P. maximum ‘Zuri’, and Andropogon gayanus. The oviposition results demonstrated that in the choice test there was a change in the stink bug’s behavior in relation to grasses four hours after infestation, with U. humidicola, P. maximum ‘Mombaça’ and ‘Zuri’, U. brizantha ‘Marandu’ and A. gayanus, proving to be less attractive to insects. It is concluded that U. humidicola, P. maximum ‘Mombaça’ and ‘Zuri’, U. brizantha ‘Marandu’, and A. gayanus are less attractive to B. pulchellus. A. gayanus and P. maximum ‘Mombaça’ and ‘Zuri’ showed non-preference resistance (antixenosis) to oviposition by B. pulchellus. The resistance of U. humidicola, P. maximum ‘Zuri’, and A. gayanus to B. pulchellus may be associated with greater compaction and lignification of the parenchyma and sclerenchyma cells of leaf sheaths.

RESUMO Os percevejos-das-gramíneas [Blissus pulchellus Montandon (Hemiptera: Blissidae)] sugam a seiva de espécies forrageiras suscetíveis e injetam toxinas que destroem os vasos condutores e dificultam o transporte de água e nutrientes, levando as plantas a morte. Assim, o objetivo deste estudo foi avaliar a resistência por antixenose e tolerância em oito poáceas forrageiras à B. pulchellus e comparar as características anatômicas dos tecidos das bainhas foliares de espécies/cultivares resistentes e suscetíveis. Os ensaios foram conduzidos em laboratório e casa de vegetação, em testes com e sem chance de escolha, utilizando-se as forrageiras: Urochloa ruziziensis, U. humidicola, U. brizantha ‘Piatã’, U. brizantha ‘Paiaguás’, U. brizantha ‘Marandu’, Panicum maximum ‘Mombaça’, P. maximum ‘Zuri’, e Andropogon gayanus. Os resultados de oviposição demonstraram que no teste de escolha houve uma mudança no comportamento do percevejo em relação às gramíneas quatro horas após infestação, sendo U. humidicola, P. maximum ‘Mombaça’ e ‘Zuri’, U. brizantha ‘Marandu’ e A. gayanus menos atrativos para os insetos. Conclui-se que U. humidicola, P. maximum ‘Mombaça’ e ‘Zuri’, U. brizantha ‘Marandu’, e A. gayanus são menos atrativas a B. pulchellus. A. gayanus, e P. maximum ‘Mombaça’ e ‘Zuri’ apresentam resistência do tipo não-preferência para oviposição a B. pulchellus. A resistência de U. humidicola, P. maximum Zuri, e A. gayanus a B. pulchellus pode estar associada a maior compactação e lignificação das células dos tecidos parenquimático e esclerenquimático das bainhas foliares. percevejosdasgramíneas percevejos Blissus Hemiptera (Hemiptera Blissidae Blissidae) nutrientes morte Assim B espéciescultivares cultivares vegetação utilizandose utilizando se ruziziensis U humidicola ‘Piatã, Piatã ‘Piatã , ‘Piatã’ ‘Paiaguás, Paiaguás ‘Paiaguás ‘Paiaguás’ ‘Marandu, Marandu ‘Marandu ‘Mombaça, Mombaça ‘Mombaça P ‘Zuri, Zuri ‘Zuri infestação insetos Concluise Conclui nãopreferência não preferência

ABSTRACT Introduction: The superiority of the functional results of robot-assisted radical prostatectomyis still controversial. Despite this, it is known that minimally invasive surgery obtains better results when analyzing blood loss, blood transfusion and length of stay, for example. Several studies have analyzed the impact of the resident physician's involvement on the results of urological surgeries. The simple learning curve for robot-assisted radical prostate surgery is estimated to be around 10 to 12 cases. Learning curve data for robotic surgeons is heterogeneous, making it difficult to analyze. Rare studies compare the results of a radical prostatectomy of an inexperienced surgeon starting his training in open surgery, with the results of the same surgeon, a few years later, starting training in robotic surgery. Objective: to analyze the results of open radical prostatectomy surgeries (ORP) performed by urology residents, comparing them to the results of robot-assisted radical prostatectomy (RARP), performed by these same surgeons, after completing their training in urology. Materials and methods: a retrospective analysis of the cases of only 3 surgeons was performed. 50 patients underwent ORP (group A). The surgeons who operated on the ORP patients were in the 3rd and final year of the urology residency program and beginners in ORP surgery, but with at least 4 years of experience in open surgery. The same surgeons, already trained urologists, began their training in robotic surgery and performed 56 RARP surgeries (group B). For the comparative analysis, data were collected on age, number of lymph nodes removed, surgery time, hospitalization time, drain volume, drain permanence time, indwelling bladdercateter (IBC) permanence time, positive surgical margin, biochemical recurrence, risk classification (ISUP), intra and postoperative complications, urinary incontinence (UI) and erectile dysfunction (ED). The console used was the Da Vinci Si, from Intuitive®. For statistical analysis, the Shapiro-Wilk test verified that the data did not follow normality, the Levene test guaranteed homogeneity, and the Mann-Whitney test performed the comparative analysis of the quantitative data. For the analysis of qualitative data, the Chi-square test was used for nominal variables and the Mann-Whitney U test for ordinal variables. Additionally, the Friedman test analyzed whether there was an improvement in the perception of UI or ED over the months, for each group individually (without comparing them), and the post-hoc Durbin-Conover test, for the results with statistically significant difference. We used a p-value < 0.05, and the Jamovi® program (Version 2.0). Results: there was no statistically significant difference between the groups for age, number of lymph nodes removed, positive surgical margin, biochemical recurrence, risk classification and urinary incontinence. Additionally, we observed that the surgical time was longer in group B. On the other hand, the length of stay, drain volume, drain time, IBC time, complication rate and levels of erectile dysfunction in the third and sixth months were higher in group A, when compared to group B. We also observed that there was no evolutionary improvement in ED over the months in both groups, and that there was a perception of improvement in UI from the 1st to the 3rd month in group A, and from the 1st to the 6th month, and from the 3rd to the 12th month, in group B. Conclusion: the learning curve of RARP is equivalent to the curve of ORP. In general, the results for the robotic group were better, however, the functional results were similar between the groups, with a slight tendency of advantage for the robotic arm.

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.

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- (
