Abstract This research aims to investigate the syntactic representation of the perfect aspect. More specifically, we intend to verify the morphosyntactic realizations of universal perfect (UP), resultative perfect (ResP) and experiential perfect (ExP) associated to the past and to the indicative mood in Brazilian Portuguese (BP). For this purpose, five hours of spontaneous speech were analyzed and a gap-filling task was applied to 62 native speakers of BP. The results evidenced that UP is conveyed by the imperfective past and the auxiliary verb “estar” (‘to be’) in the imperfective past + gerund; ResP is conveyed by past perfect (with the auxiliary verbs “ter” (‘to have’) and “haver” (‘there to be’), simple past, past perfect simple and “acabar” (‘to finish’) in the past perfect compound with the auxiliary verb “ter” (‘to have’) + ‘de’ (‘of’) + infinitive; and ExP is conveyed by the past perfect compound with the auxiliary verbs “ter” (‘to have’) and “haver” (‘there to be’), simple past and past perfect simple. We discussed that the results corroborate Rodrigues and Martins’s (2019) proposal that there are three perfect phrases in the syntactic tree: Universal Perfect Phrase (UPerfP) to UP, Resultative Perfect Phrase (ResPerfP) to ResP, and Experiential Perfect Phrase (ExPerfP) to ExP.

Resumo Objetiva-se, nesta pesquisa, investigar a representação sintática do aspecto perfect. Mais especificamente, pretende-se verificar as realizações morfossintáticas de perfect universal (PU), resultativo (PRes) e experiencial (PEx) associados ao tempo passado e ao modo indicativo no português brasileiro (PB). Para tanto, foram analisadas cinco horas de fala espontânea e foi aplicado um teste de preenchimento de lacunas a 62 falantes nativos do PB. Os resultados evidenciam que o PU é veiculado por meio de pretérito imperfeito e “estar” no pretérito imperfeito + gerúndio; o PRes é veiculado por meio de pretérito mais-que-perfeito composto (com auxiliares “ter” e “haver”), pretérito perfeito, pretérito mais-que-perfeito simples e “acabar” no pretérito mais-que-perfeito composto com auxiliar “ter” + preposição “de” + infinitivo; e o PEx é veiculado por meio de pretérito mais-que-perfeito composto (com auxiliares “ter” e “haver”), pretérito perfeito e pretérito mais-que-perfeito simples. Os resultados corroboram a proposta de Rodrigues e Martins (2019) de que há três sintagmas de perfect na árvore sintática: o Sintagma de Perfect Universal (UPerfP) para o PU, o Sintagma de Perfect Resultativo (ResPerfP) para o PRes e o Sintagma de Perfect Experiencial (ExPerfP) para o PEx.

ABSTRACT. Food production in a sustainable way is based on the association between animals and vegetables to minimize costs, environmental impact, and the use of insums in the breeding process. The objective of this work was to evaluate the effect of the inclusion of pumpkin seed flour (Cucurbita pepo L.) in the diet on the performance of early-stage pigs and the reduction of endoparasites in a commercial rearing system. The experimental design was completely randomized, with three treatments and six replicates, and the experimental unit consisted of two animals, totaling 36 animals. The treatments were the basal diet and two levels of inclusion of pumpkin seed: 5 and 10%. The animals were of the Agroceres line, with 42 days of age and an average weight of 12 kg. The animals and rations were weighed at the beginning and at the end of the 35-day experimental period to obtain the performance variables. A bromatological analysis was performed to evaluate the composition of pumpkin seed and for parasitic analysis, feces were collected individually from the animal. There was no significant effect for the Tukey test at the level of 5% probability, of the inclusion of pumpkin seed flour on in the parameters of weight gain and feed conversion. Was observed the reduction of helminth eggs present in feces using egg count and oocysts per gram of feces (OPG), performed at the beginning and end of the experiment. It is indicated the inclusion of 10% of pumpkin flour in the feeding of pigs in the initial phase by reducing contamination by verminosis and does not alter animal performance.

Abstract This study presents findings from research conducted with indigenous and peasant students (n = 53) in their first year of the Rural Education Degree (Countryside Education) program at a public university in the Brazilian Midwest. We investigated previous knowledge and methods for developing entomological knowledge using structured questionnaires with open, closed, and multiple-choice questions. As a result, we discovered 24 distinct types of animals known as insects. Indigenous peoples conceptualized insects using ecological principles, whereas peasants approached the subject from health and emotional perspectives. Our findings revealed that indigenous students’ prior entomological knowledge was primarily developed within their families, while peasant students developed it at school. This study provides important insights into pre-existing knowledge and the development of entomological understanding in an intercultural setting. It encourages reflection on the interactions of traditions, folk knowledge, and scientific understanding. n 53 Countryside Midwest open closed multiplechoice multiple choice questions result 2 principles perspectives families school preexisting pre existing setting traditions 5

ABSTRACT The use of substances that can mitigate the harmful effects of salt stress is a promising alternative for the use of saline water, especially in semi-arid regions. The aim of this study was to evaluate the effect of different concentrations of hydrogen peroxide in mitigating salt stress in the mini watermelon grown in a hydroponic system. The study was carried out in a greenhouse, in an area belonging to the Federal University of Campina Grande, Pombal, Paraíba. The experimental design was completely randomised using a split-plot factorial scheme with four levels of electrical conductivity for the nutrient solution-ECns (2.1, 3.1, 4.1, and 5.1 dS m-1) considered the plots, and four concentrations of hydrogen peroxide-H2O2 (0, 20, 40, and 60 μM) the subplots, with five replications. The foliar application of hydrogen peroxide in concentrations of between 17 and 20 µM mitigated the effects of salt stress on stomatal conductance, the rate of CO2 assimilation, carboxylation efficiency, and carotenoid content in the mini watermelon up to an ECns of 5.1 dS m-1. Foliar application of hydrogen peroxide in concentrations greater than 20 µM intensified the effects of salt stress on gas exchange and the synthesis of photosynthetic pigments in the mini watermelon. Furthermore, there was an increase in electrolyte leakage in the leaf blade. water semiarid semi arid regions system greenhouse Grande Pombal Paraíba splitplot split plot solutionECns solution 2.1, 21 2 1 (2.1 31 3 3.1 41 4 4.1 51 5 5. m1 m m-1 plots peroxideH2O2 peroxideHO H2O2 H O peroxide-H2O 0, 0 (0 40 6 μM subplots replications conductance CO assimilation efficiency m1. 1.

Resumo Este estudo teve como objetivo determinar e comparar os valores de energia metabolizável e os coeficientes de metabolizabilidade de três tipos de óleo de milho (bruto, semi-refinado e ácido) em frangos de corte. Foram usados 240 frangos da linhagem Cobb500™, distribuídos aleatoriamente em gaiolas metabólicas com quatro tratamentos, 10 repetições e 6 aves por unidade experimental. As aves foram alimentadas com rações específicas para cada tratamento, e a coleta total de excretas foi realizada dos dias 23 a 27. Os valores de energia bruta (EB), energia metabolizável aparente (EMA) e energia metabolizável aparente corrigida pelo balanço de nitrogênio (EMAn) foram calculados para cada tipo de óleo. Os coeficientes de metabolizabilidade do extrato etéreo (CMEE) também foram determinados. A análise estatística dos resultados foi realizada por meio do teste de Tukey ao nível de 5% de probabilidade. Houve diferença significativa para os valores de EMA e CMEE (P<0,05). O óleo de milho bruto apresentou maiores valores EMA quando comparado ao óleo de milho ácido. O mesmo comportamento foi verificado para o CMEE (P<0,05). Os valores encontrados para os óleos foram: óleo de milho bruto - EB: 9330 kcal/kg, EMA: 8916,84 kcal/kg, EMAn: 8905,60 kcal/kg, CMEE: 97,14%; óleo de milho semi refinado - EB: 9480 kcal/kg, EMA: 8547,99 kcal/kg, EMAn: 8303,46 kcal/kg, CMEE: 96,64%; óleo de milho ácido - EB: 9114 kcal/kg, EMA: 7197,73 kcal/kg, EMAn: 7515,68 kcal/kg, CMEE: 96,17%. bruto, (bruto semirefinado corte 24 Cobb500 Cobb Cobb500™ tratamentos 1 experimental tratamento 2 27 EB, EB , (EB) (EMA EMAn (EMAn (CMEE determinados 5 probabilidade P<0,05.

Abstract This study aims to determine and compare the metabolizable energy values and metabolizability coefficients of three types of corn oil (crude, semi-refined, and acid) for broiler chickens. 240 Cobb500™ chickens were randomly allocated into metabolic cages, resulting in four treatments, ten replicates, and six birds per experimental unit. The birds fed on diets specific to each treatment. Total excreta was collected from the day 23rd to the 27th. Gross energy (GE), apparent metabolizable energy (AME), and nitrogen-corrected apparent metabolizable energy (AMEn) were calculated for each oil type. The metabolizability coefficient values of ether extracts (MCEE) were also determined. Statistical analysis was performed using Tukey test at a 5% probability. There was a significant difference in AME and MCEE values (P<0.05). Crude corn oil showed higher AME and MCEE values than acid corn oil. The findings are crude corn oil - GE: 9,330 kcal/kg, AME: 8,916.84 kcal/kg, AMEn: 8,905.60 kcal/kg, MCEE: 97.14%; semi-refined corn oil - GE: 9,480 kcal/kg, AME: 8,547.99 kcal/kg, AMEn: 8,303.46 kcal/kg, MCEE: 96.64%; acid corn oil - GE: 9,114 kcal/kg, AME: 7,197.73 kcal/kg, AMEn: 7,515.68 kcal/kg, MCEE: 96.17%. crude, (crude semirefined, semirefined semi refined, refined 24 Cobb500 Cobb cages treatments replicates unit treatment rd 27th th GE, GE , (GE) AME, (AME) nitrogencorrected nitrogen corrected AMEn (AMEn type (MCEE determined 5 probability P<0.05.

Resumo Toxoplasma gondii é um coccídio que infecta quase todos os animais de sangue quente, incluindo aves. A Reserva Biológica do Atol das Rocas, localizada no Nordeste do Brasil, é o único atol do Atlântico Sul que abriga a maior população de aves marinhas tropicais do oeste do Oceano Atlântico. O objetivo deste estudo foi verificar a ocorrência de anticorpos anti-T. gondii em aves marinhas do Atol das Rocas que foram capturadas manualmente. Amostras de sangue foram obtidas e anticorpos avaliados pelo teste de aglutinação modificado (>5). Foram amostradas 267 aves de sete espécies, pertencentes a três famílias (Sternidae, Fregatidae e Sulidae) e duas ordens (Charadriiformes e Suliformes). Das 267 aves, 20 (7,3%) foram soropositivas sendo: nove das 48 viuvinhas-marrons (Anous stolidus), uma das 26 viuvinhas-negras (Anous minutus), três das 20 fragatas (Fregata magnificens), cinco dos 95 trinta-réis-das-rocas (Onychoprion fuscatus) e dois dos 20 atobás-de-pés-vermelhos (Sula sula). Nenhum dos 33 atobás grandes (Sula dactylatra) e dos 25 atobás-pardos (Sula leucogaster) estavam soropositivos. Os títulos de anticorpos foram 5 (n=6), 10 (n=4), 20 (n=3), 40 (n=6) e 160 (n=1).

Abstract Toxoplasma gondii is a coccidian that infects almost all warm-blooded animals, including birds. Rocas Atoll Biological Reserve, located in the northeast of Brazil, is the only atoll in the South Atlantic, and home to the largest population of seabirds in the western Atlantic. In this study the occurrence of T. gondii antibodies in seabirds from Rocas Atoll were determined. Birds were manually captured, blood samples were taken, and antibodies detected by the modified agglutination test (>5). In total, 267 birds of seven species belonging to three families (Sternidae, Fregatidae and Sulidae) and two orders (Charadriiformes and Suliformes) were sampled. Out of the 267 samples, 20 (7.3%) were seropositive: nine out of 48 brown noddies (Anous stolidus), one out of 26 black noddies (Anous minutus), three out of 20 magnificent frigatebirds (Fregata magnificens), five out of 95 sooty terns (Onychoprion fuscatus) and two out of 20 red-footed boobies (Sula sula). None of the 33 masked boobies (Sula dactylatra) and the 25 brown boobies (Sula leucogaster) were seropositive. The antibody titers were 5 (n=6), 10 (n=4), 20 (n=3), 40 (n=6) and 160 (n=1). Due to the uniqueness of this environment, monitoring the seabirds is suggested to maintaining this Conservation Unit. warmblooded warm blooded animals Reserve Brazil Atlantic T determined captured taken >5. >5 .

Abstract This article presents the development of a liquid-level sensor using fiber optic Bragg gratings (FBG). The sensor comprises a carbon-fiber-reinforced polymers (CFRP) diaphragm packaging an embedded FBG to measure strain. A mathematical analysis determines the FBG response to the pressure exerted by a liquid column over the packaged sensor. The experimental arrangement consists of an acrylic tube with a sensor at the bottom. FBG signals were acquired using a DI 410 optical interrogator manufactured by HBM. A finite element simulation with Ansys was performed to determine the most reposeful position from the FBG sensor. The experimental results show the analysis of eight repetitions of the water column ranging from 10 cm to 60 cm using 10 cm steps. The sensor showed a linear response, with a coefficient of determination of 0.999, and a sensitivity of 4.1 pm/cm; and the maximum standard deviation is 0.64 pm. Although water is used in the calibration process, other liquids could also be used, obtaining a different angular coefficient depending on the density of the liquid used. liquidlevel level FBG. .

Abstract Objective The present study compares the analgesic efficacy of two techniques to perform non-surgical reduction: fracture hematoma block and radial nerve supracondylar block. Methods Forty patients with fractures of the distal third of the radius, who required reduction, were selected in a quasi-randomized clinical trial to receive one of the anesthetic techniques. All patients signed the informed consent form, except for those who did not wish to participate in the study, had neurological injury, had contraindication to the procedure in the emergency room, or with contraindication to the use of lidocaine. To measure analgesia, the numerical pain rate scale was used at four different moments: preblock, postblock, during reduction, and after reduction; then three differences were calculated: the first between before and after blocking; the second between during reduction and after blockade; and the third between before blocking and after reduction. Results The fracture hematoma and supracondylar block groups showed the following mean values, respectively: 3.90 (1–10) and 3.50 (-6–10) in difference 1; 4.35 (-5–10) and 5.00 (-3–10) in difference 2; and 4.65 (1–10) and 3.80 (-3–10) in difference 3.

Resumo Objetivo O estudo compara a eficácia analgésica de duas técnicas para realizar redução incruenta: o bloqueio de hematoma da fratura e o bloqueio supracondilar de nervo radial. Métodos Quarenta pacientes com fraturas do terço distal do rádio, que necessitassem redução, foram selecionados em um ensaio clínico quasi-randomizado, para receber uma das técnicas anestésicas. Todos os pacientes assinaram o termo de consentimento ou assentimento, com exceção daqueles que não desejassem participar do estudo, tivessem lesão neurológica, com contraindicação ao procedimento na sala de emergências, ou com contraindicação ao uso da lidocaína. Para aferir a analgesia foi utilizada a escala numérica da dor em quatro momentos distintos: pré-bloqueio, pós-bloqueio, durante a redução e após a redução; em seguida, foram calculadas três diferenças: a primeira entre antes e após o bloqueio; a segunda entre durante a redução e após o bloqueio; e a terceira entre antes do bloqueio e após a redução. Resultados Os grupos do bloqueio de hematoma de fratura e bloqueio supracondilar apresentaram respectivamente os seguintes valores médios: 3.90 (1–10) e 3.50 (-6–10) na diferença 1; 4.35 (-5–10) e 5.00 (-3–10) na diferença 2; e 4.65 (1–10) e 3.80 (-3–10) na diferença 3.

Abstract In this work, measuring capabilities of a Sagnac Interferometer-based Distributed Optical Fiber Sensor (DOFS) system are demonstrated by comparing its results to a conventional amplitude-based Distributed Acoustic Sensing (DAS) system. Through a set of three different experiments, it was demonstrated that both sensing systems can detect and locate dynamical deformation along the fiber, in addition to determining its frequency components. The coherent amplitude-based DAS presented a lower background noise. In contrast, even though the Sagnac interferometry-based system presented low-frequency noise in the measurements, it is less susceptible to harmonic distortion for higher amplitude deformations since its sensing principles rely on the measurement of the accumulated phase rather than the amplitude of the backscattered signal purely.

The FBG sensor is applied to one subject's forearm to measure the deformation as a result of the index and middle fingers when moved individually. It is possible to control a one joint model prosthesis allied to a compliant hand mechanism through signal analyses. Each finger movement has its features, such as its amplitude, which opens the possibility of using those to control different parts of the prosthesis, joint rotation by the middle finger, and compliant hand movement by the index finger. This paper presents results regarding prosthesis assembling, Hypertext Transfer Protocol (HTTP) communication latency between prosthesis and computer and tests with pre-acquired and processed FBG signal data. The prosthesis wrist rotation movement is related to the middle finger signal, and its compliant mechanism actuation is due to index finger signal. The communication between prosthesis and the computer had a mean latency of 140 ms and a standard deviation of 18 ms. The results demonstrate the potential for using the sensor system and automated prosthesis in other applications involving real-time forearm sensing, multi-finger signal analysis, and prosthetic movement.

Abstract Vibration analysis systems are used to assess the operational condition of machines and electromechanical components in various applications. This work presents a measurement and feature extraction system that analyzes dynamic strain patterns in signals measured by fiber Bragg grating (FBG). The features were used to identify different simulated operational conditions in an electromechanical relay. The selection of the best feature space in the first approach was performed by statistical criteria that determine the threshold values and frequency bands to calculate each signal's switching time and power spectral density (PSD). These parameters are used in the support vector machine (SVM) algorithm, which presents 98 % accuracy for distinguishing four distinct conditions. Another methodology for extracting features, called wavelet scattering transform (WST), was used to demonstrate that it is possible to achieve even better performance levels. The results allow extending the methodology to more complex systems. applications FBG. FBG . (FBG) relay signal s PSD. PSD (PSD) SVM (SVM algorithm 9 WST, WST , (WST) levels (FBG (PSD (WST

In this study, a hydroxyapatite (HA) coating derived from the scales of the Amazonian fish pirarucu (Arapaima gigas) was produced using calcination at 500 and 750 °C and deposited on AISI 316 stainless steel substrate using the process of thermal spraying, high velocity suspension plasma spray (HVSPS). To verify its potential, this material was characterized by X-ray diffraction (XRD), by which characteristic peaks of hydroxyapatite were evidenced. Via X-ray fluorescence (XRF) of the samples, it was observed that the Ca/P ratio was equal to 2.00. Using the Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy, it was possible to observe the characteristic bands of the HA. For the coating, the mechanical nanoindentation test showed mean Vickers microhardness (VH) values of 93.25 VH for the hydroxyapatite and of 196.57 HV for the substrate. The modulus of elasticity (EIT) was 77.85 GPa for the hydroxyapatite coating and 136.45 GPa for the substrate. Optical microscopy showed that the coating was homogeneously deposited. study HA (HA Arapaima gigas 50 75 C 31 spraying HVSPS. HVSPS .
