Vibrational anharmonicity of A-band related optical center and its temperature dependence studied by femtosecond laser excitation in bulk natural diamond
Authors: Kudryashov Sergey , Danilov Pavel , Smirnov Nikita , Kovalov Volodymyr
Published: April 2024

Unusual A-band spectra with well-resolved quasi-periodical phonon progressions of multiple peaks (N\(\sim \)9) were excited in a natural diamond by 515-nm, 300-fs laser pulses at variable pre-heating temperatures of 24-200oC. The non-radiative multi-phonon part of the relaxation path was comparable with the total relaxation energy (zero-phonon line energy), pointing out some extended defects (e.g., dislocations) as the recombination center of the A-band emission. The derived temperature dependences of the peak intensities, separations and half-widths of the separate spectral peaks in the A-band phonon progressions indicate the different trends for vibration-free zero-phonon transition and vibration-related lower-energy transitions to high vibrational levels of the bottom state – lower thermal damping and more softened phonon for the zero-phonon transition, also implying the extended defect origin of the A-band photoluminescence.
Puta ou Santa? Os antagônicos discursos sobre mulheres nas letras de funk interpretadas por homens
Authors: Peres Fabíola
Published: April 2024

Assim como o dinheiro, a ostentação, a violência e o crime, as relações sexuais e afetivas com mulheres compõem a masculinidade funk. Na maioria das letras escritas e interpretadas por homens, mulheres são descritas enquanto objetos sexualizados descartáveis, que conferem status aos seus “proprietários”. A análise e a categorização de letras de funk brasileiro dos últimos 15 anos possibilitam, entretanto, observar tratamento completamente contrário de outra figura feminina: a mãe. Em diversas canções do chamado “funk consciente”, cantores declaram amor por suas genitoras, caracterizado por uma certa devoção e um forte desejo de proporcionar a elas um futuro com segurança e estabilidade financeira. A partir de tais observações, este artigo destina-se a identificar as diferenças existentes na aparente oposição entre a figura da mãe e das demais mulheres no que se refere às letras de funk interpretadas por homens, as percebendo enquanto um dos elementos que constituem as masculinidades funk.

Published: April 2024

This study aims to coat Ti6Al4V alloy with Ti-xHA (x = 2.5−10 wt%) mixture to improve its surface properties. A new approach using a powder metallurgical pressure-assisted sintering method was applied to the coating process. The in situ sintering and coating process was performed at 950°C for 45 min in a vacuum atmosphere of 10–4 mbar. A pressure of 50 MPa was applied during the sintering process. Staphylococcus aureus (ATCC® 29213TM) and Escherichia coli (ATCC® 25922TM) cultures were used to determine the antibacterial activity of the sintered and coated samples. The electrochemical properties of the samples were studied by Tafel extrapolation and potentiodynamic polarisation tests. The results showed that the coating layer containing 7.5 wt% of hydroxyapatite (HA) increased the antibacterial property against gram-positive and gram-negative bacterial cultures. Furthermore, it was determined that the icorr value of the material decreased and the corrosion resistance improved with an increasing HA ratio. In addition, no active-passive oxidation zone formation was observed up to 2000 mV in the HA-added samples.
Collision Avoiding Max-Sum for Mobile Sensor Teams
Authors: Pertzovsky Arseniy , Zivan Roie , Agmon Noa
Published: April 2024

Recent advances in technology have large teams of robots with limited computation skills work together in order to achieve a common goal. Their personal actions need to contribute to the joint effort, however, they also must assure that they do not harm the efforts of the other members of the team, e.g., as a result of collisions. We focus on the distributed target coverage problem, in which the team must cooperate in order to maximize utility from sensed targets, while avoiding collisions with other agents. State of the art solutions focus on the distributed optimization of the coverage task in the team level, while neglecting to consider collision avoidance, which could have far reaching consequences on the overall performance. Therefore, we propose CAMS: a collision-avoiding version of the Max-sum algorithm, for solving problems including mobile sensors. In CAMS, a factor-graph that includes two types of constraints (represented by function-nodes) is being iteratively generated and solved. The first type represents the task-related requirements, and the second represents collision avoidance constraints. We prove that consistent beliefs are sent by target representing function-nodes during the run of the algorithm, and identify factor-graph structures on which CAMS is guaranteed to converge to an optimal (collision-free) solution. We present an experimental evaluation in extensive simulations, showing that CAMS produces high quality collision-free coverage also in large and complex scenarios. We further present evidence from experiments in a real multi-robot system that CAMS outperforms the state of the art in terms of convergence time.
USN: A Robust Imitation Learning Method against Diverse Action Noise
Authors: Yu Xingrui , Han Bo , Tsang Ivor W.
Published: April 2024

Learning from imperfect demonstrations is a crucial challenge in imitation learning (IL). Unlike existing works that still rely on the enormous effort of expert demonstrators, we consider a more cost-effective option for obtaining a large number of demonstrations. That is, hire annotators to label actions for existing image records in realistic scenarios. However, action noise can occur when annotators are not domain experts or encounter confusing states. In this work, we introduce two particular forms of action noise, i.e., state-independent and state-dependent action noise. Previous IL methods fail to achieve expert-level performance when the demonstrations contain action noise, especially the state-dependent action noise.  To mitigate the harmful effects of action noises, we propose a robust learning paradigm called USN (Uncertainty-aware Sample-selection with Negative learning). The model first estimates the predictive uncertainty for all demonstration data and then selects sampleswith high loss based on the uncertainty measures. Finally, it updates the model parameters with additional negative learning on the selected samples. Empirical results in Box2D tasks and Atari games show that USN consistently improves the final rewards of behavioral cloning, online imitation learning, and offline imitation learning methods under various action noises. The ratio of significant improvements is up to 94.44%. Moreover, our method scales to conditional imitation learning with real-world noisy commands in urban driving
IMPACT OF RECIRCULATION ZONES ON THE NEAR-FIELD ENTRAINMENT CHARACTERISTICS OF A SWIRLING LIQUID JET
Authors: Sahu Toshan Lal , Chetan Ujjwal , Kar Prabir Kumar , Dhopeshwar Saurabh , Mahato Jagannath , Das Prasanta Kumar , Lakkaraju Rajaram
Published: April 2024

Using three-dimensional numerical simulations, we analyze the entrainment of the ambient fluid at the interface of a swirling liquid jet for swirl numbers of 0.5 ≤ S ≤ 1.55 and moderate axial Reynolds number of Re = 50 and Re = 100. We have identified the generation of axial and azimuthal shear layers developing at the interface and visualized the path traced out by the ambient air. The results indicate that the surrounding air exhibits toroidal recirculation zones, which causes the accumulation of ambient air at the interface leading to the engulfment of the ambient fluid. We also observed that the entrainment rate is higher for higher swirl numbers. Furthermore, we have also estimated the entrainment coefficients for different swirl numbers, which range from 0 to 0.15.
Análisis de los sistemas de medición de la desnutrición para diseñar una política regional nutricional en América Latina y el Caribe
Authors: Herrero Olarte Susana
Published: April 2024

Una política regional nutricional en América Latina y el Caribe puede ofrecer herramientas clave que permitan erradicar la desnutrición. Para diseñarla es preciso cuantificar y localizar el problema. Existen cuatro sistemas generalmente aceptados para medir la desnutrición, de estos, el método antropométrico suele presentar los resultados más distintos. ¿Es este el método más adecuado para cuantificar la desnutrición? Para ello, se seleccionaron seis países de la región y se valoró cuál sistema presenta los datos más coherentes con otros indicadores socioeconómicos afectados por la desnutrición, como son: pobreza, salud, mortalidad y educación. Los resultados indican que el método basado en análisis antropométricos comparativos muestra datos menos coherentes con la realidad socioeconómica de cada país. Concluyendo así que, para diseñar una política nutricional regional, no se deberían utilizar métodos antropométricos debido a que no recogen, entre otros factores, las diferencias entre los grandes grupos étnicos de la región.
Animal Offerings in Ritual, Economic and Social Contexts in Britannia
Authors: Roberts David , Rainsford Clare
Published: April 2024

Animals were central to ritual activity at religious sites in Britannia, in sacrifice, iconography, structured deposition and feasting. While animal remains from shrine and temple sites have been regularly studied, there have been few attempts to integrate them with their ‘secular’ landscape context. Recent theoretical developments offer an opportunity to bridge that gap and better contextualize ritual and religious acts involving animals. Using the recently published South Wiltshire Temple, we argue that all animals, from major domesticates to wilder or more exotic animals such as deer, chickens and (figural representations of) leopards were invested with meaning through everyday practices and associations. These meanings accordingly influenced their use within ritual practices. Collectively, the ritualized deposition of animals may provide insights into the experience of the Roman world, providing a case study of how practice theory and glocalization can combine to produce innovative insights into Britannia.
Sensory and consumer science as a valuable tool to the development of quinoa-based food products: More than three decades of scientific evidence
Authors: Eduardo Karina , Bedoya-Perales Noelia , Escobedo-Pacheco Elias , Saldaña Erick
Published: April 2024

Solutions are needed to address both hunger and the promotion of healthy and sustainable diets. Quinoa, a nutritious and sustainable Andean grain, is a versatile option for creating new foods. Over the years, several technological advancements have been made to include quinoa in various food products. However, there is still a need for solid scientific evidence on the impact of quinoa on the product's acceptance. To address this scientific knowledge gap, this work aims to analyze the scientific literature over the last three decades regarding the sensory and hedonic impact of adding quinoa to food products. To do so, bibliometric methods based on the Scopus and Annual Scientific Production databases were used. After selecting and screening using the PRISMA method, seventy-four articles from 1991 to 2024 were analyzed, identifying relationships between keywords in the analyzed studies, forming a co-occurrence and co-authorship network. Results showed that quinoa has great nutritional potential when added to different food products, but its instrumental and sensory properties are modified. The nine-point hedonic scale was used to measure product acceptability in 47% of the articles. Studies on bakery products have shown that increasing the concentration of quinoa in the product formulation decreases the acceptance of the final product in 67% of cases. It is recommended to include consumer demands from a sensory and hedonic perspective when developing new products. The scientific and industrial community is encouraged to develop new food products catering to a broader consumer range.

Published: April 2024

Introdução: A demanda por alimentos e nutrientes possui crescimento exponencial, em razão do aumento populacional. Com isso, faz necessária a aplicação de técnicas que melhoraram os processos produtivos, e com sustentabilidade otimize a produtividade das áreas cultivadas, ou seja, que haja o aumento produtivo sem que haja a necessidade de aumento da área. Objetivos: O presente trabalho, avaliou a viabilidade do monitoramento de interferência de plantas infestantes através de drones. Materiais e Método: Para o desenvolvimento da pesquisa, foram implantadas as culturas agrícolas em áreas determinadas e entre as faixas de culturas florestais. Foram realizadas avaliações das plantas infestantes com o uso de imagens aéreas e imagens registradas com uso de câmeras de celulares nos locais onde aos gabaritos triangulares verticais, coloridos com escalas graduais utilizados na pesquisa foram instalados. Foram realizados registros de imagens com o uso do drone em diferentes alturas de voo. As imagens foram analisadas e ampliadas para a classificação de incidência e interferência das plantas infestantes. Além das imagens de drone, foram analisadas as imagens registradas com a câmera de celular a fim de comparar o reconhecimento e avaliação das plantas infestantes, buscando assim, determinar o melhor método de avaliação. Resultados: Após avaliação das imagens e comparações, foi possível verificar a metodologia de reconhecimento das plantas infestantes em suas diferentes fases de desenvolvimento. A avaliação de plantas infestantes por meio de drones traz ao produtor e/ou técnico uma visão ampla sobre a dominância das plantas infestantes ou do cultivo de interesse, ou seja, é possível com as imagens aéreas visualizar a área total, e o nível geral de ocupação do espaço pelas plantas infestantes, no entanto, a análise visual morfológica da planta como estádio vegetal, com as imagens aéreas não trouxeram uma eficiência relevante quando buscamos visualizar a interferência, pois devido qualidade das imagens capturadas não é possível o reconhecimento e a avaliação do estágio de interferência das plantas infestantes, em relação as culturas de interesse. Considerações finais: As imagens obtidas com a câmera do celular, trazem uma maior visualização da planta, e do real estádio vegetativo, porém, estas as imagens não permitem uma avaliação ampla da área produtiva. No desenvolvimento do projeto, nota-se que ambos os métodos são válidos, para contribuir na decisão sobre a implementação de técnicas de controle das plantas infestantes contudo ao analisar as imagens isoladamente é possível uma avaliação equivocada das necessidades de manejo. Com base no presente trabalho é recomendado que ambos os métodos sejam empregados em conjunto para otimizar o processo de avaliação e sua eficiência e não isoladamente.

Powder adhesion on tools during pharmaceutical tablet manufacturing
Authors:   , Thomas James V , Zavaliangos Antonios
Published: April 2024

The occurrence of defects in pharmaceutical tablets during manufacture can have disastrous consequences that impact quality, time, cost, and patients. 'Sticking', is a prominent tablet defect that results in the removal of material from the tablet surface after each compaction and its accumulation on the punch faces during tablet production. Currently, the understanding on the various mechanisms of sticking and methods of its assessment are inadequate. In this work, a novel laser reflection sensor was developed to quantify sticking with high sensitivity, live measurements, contact-free and simple to operate. The laser sensor compensates for the drawbacks of currently available techniques. Current techniques are largely unreliable or require large quantities of active drug or require stopping the press for assessment or not accessible as they require the use of specialized and complex instruments. Moreover, a novel material-sparing methodology (Single Tablet Multi-Compaction, STMC) for the assessment of sticking was introduced here. The results presented in this work demonstrate that STMC is a viable method which requires only a few tablets to assess sticking. Together, the STMC methodology and the laser sensor aim to address a pressing need in the pharmaceutical industry; that is to enable the early warning and mitigation of sticking to avoid its disastrous occurrence during production. In this work, the laser sensor enabled the discovery of a set of conditions that affect sticking that has not been reported before in literature. The effect of pre-compression pressure, punch temperature, and punch surface contamination were studied, and all found to strongly affect sticking. The results provide new insights into the complex mechanisms by which sticking occurs.
The Role of Mechanosensitive, IB4-Positive Nociceptive Afferent Input in Forelimb Motor Function and Rehabilitation after Spinal Cord Injury
Authors:   , Walker John Robert , Detloff Megan , Dougherty Kimberly J.
Published: April 2024

Cervical spinal cord injury (SCI) results in alterations in sensory input and motor output. These losses significantly reduce an individual's independence and quality of life. The highest priority for individuals living with SCI is regaining control and use of their arm and hand. Unfortunately, the current standard of care, physical rehabilitation, provides only minimal recovery, and promising technologies harnessing electrical stimulation, driving regeneration, and replicating motor outputs through brain-machine interfaces are still in their nascent stages. Therefore, it is of vital importance to understand the mechanistic underpinnings of rehabilitative paradigms with particular focus on alterations within neural circuits involved in sensorimotor processing so that therapies can be enhanced to improve outcomes. This dissertation focuses on the influence of aberrant nociceptive input to the spinal cord on reach-to-grasp function under normal conditions, following spinal cord injury, and during rehabilitation. Sprague-Dawley rats were given a C5 unilateral contusion on their dominant side and underwent rehabilitative strength training protocols at post-injury timepoints consistent with human treatment for SCI. Strength training after SCI improved pull force but failed to improve fine motor pellet retrieval tasks. The role of the mechanically sensitive nociceptor was tested by microinjecting a cytotoxin specifically targeted to IB4+ cells into the C7 and C8 dorsal root ganglia. More injured rats with ablated nociceptors were able to grasp food pellets compared to injured rats with intact nociceptors. When combined, mechanosensitive nociceptor ablation did not improve the efficacy of strength training after SCI. Thus, the limited effectiveness of strength training to improve reaching and grasping was determined to be independent of mechanosensitive nociceptor activity. The evidence that altered mechanosensitive nociceptor input after SCI is detrimental to the recovery of grasping provides a novel therapeutic target for motor control.

Authors:   College of Teacher Education, Batangas State University, Batangas City, Philippines, Montalbo Sherryl M.
Published: April 2024

This study developed a Teaching and Learning Material (TLM) with Augmented Reality (AR) to enhance the students’ metacognitive knowledge, namely declarative, procedural, and conditional knowledge in General Chemistry. The developed TLM has three components: the printed learning material that contains the AR trackers; a database of tactile 3D objects and animations that served as metacognitive scaffolds; and a dedicated smartphone software application specifically created for the retrieval, display and control of AR objects. The design-based research paradigm was used in the development of the Teaching and Learning Material with Augmented Reality, while the pre-experimental single group research design was employed in the assessment of the effect of scaffolds using AR on the students’ metacognitive knowledge. A Metacognitive Knowledge Test (MKT) was administered to the student participants before and after using the AR learning material system. Using the Hake factor test, the study found that the student participants achieved high learning gains for declarative and procedural metacognitive knowledge as signified by g values of 0.73 and 0.79, respectively. In terms of conditional metacognitive knowledge, the students registered a medium learning gain given by g = 0.68. It is recommended that teachers use innovative teaching and learning materials embedded with AR to enhance students’ learning attributes like metacognitive knowledge.
'The Tempest' Transformed: John Fletcher and Philip Massinger's 'The Sea Voyage'
Authors: Vaughan Virginia
Published: April 2024

This article examines John Fletcher and Philip Massinger's 1622 comedy, The Sea Voyage, as an offshoot of Shakespeare's Tempest. It traces Fletcher and Massinger's reimagination of Shakespeare's plot and characters in ways that reflect the differences between England's aspirations for the Virginia Colony in 1610 and the realities on the ground in 1621-2. Key transformations include the Fletcher-Massinger emphasis on the role of women in plantation economies as well as the hardships endured in the early days of the colony.
An Empirical Study on Cybersecurity Awareness, Cybersecurity Concern, and Vulnerability to Cyber-attacks
Authors: Mittal Chahak
Published: April 2024

The research aimed to delve into the landscape of cybersecurity awareness and concern levels within Punjab, India, shedding light on the specific demographic groups most susceptible to cyber-attacks. Through meticulous survey administration and data analysis, the study pinpointed a noteworthy vulnerability: young adult females aged 18 to 29 residing in rural Punjab, particularly those either engaged in student pursuits or currently unemployed. This demographic emerged as disproportionately prone to cyber threats.
Highlighting the gravity of this finding, the research underscores the urgency for tailored interventions to fortify the cyber defenses of this vulnerable population segment. A crucial facet of this approach involves the development of a prototype aimed at augmenting cybersecurity awareness and fostering ethical online conduct among the identified demographic. This prototype seeks to serve as a platform for delivering enhanced training modules tailored to the unique needs and challenges faced by young females in rural Punjab.
Moreover, the paper delineates a comprehensive roadmap for the implementation and evaluation of these recommendations. Central to this plan is the deployment of an application based on the proposed prototype, designed to facilitate the delivery of targeted cybersecurity education and gauge its efficacy in bolstering cyber resilience among the identified demographic.
This research not only illuminates the cybersecurity landscape in Punjab but also charts a proactive course of action aimed at mitigating vulnerabilities and empowering at-risk populations through informed intervention strategies. Through ongoing data collection and evaluation efforts, the efficacy of these interventions will be rigorously assessed, driving iterative refinement and optimization of cybersecurity initiatives tailored to the unique needs of Punjab's populace.

The estimators are based on a progressive first-failure censored plan. The study considers both maximum likelihood and Bayesian estimations using a gamma-informative prior distribution for the parameters, as well as the reliability function, hazard rate, and reversed hazard rate functions. To obtain the estimators, the paper employs Lindley’s approximation and utilizes Markov Chain Monte Carlo (MCMC) methods. The Bayes estimators are derived with respect to both symmetric (squared error) and asymmetric (linex and general entropy) loss functions. In order to assess the performance of the proposed estimators, the paper presents numerical results obtained through a simulation study involving different sample sizes.

Alienacja społeczna w dobie globalizacji na przykładzie twórczości Alda Novego
Authors: Kobylska Dominika
Published: April 2024

Analiza przedstawiona w monografii ma na celu dostarczenie odpowiedzi na pytania i hipotezy badawcze dotyczące fenomenu alienacji społecznej w dobie globalizacji ukazanego w utworach prozatorskich Alda Novego, włoskiego pisarza urodzonego w 1967 w Viggiù. Na podstawie współczesnej teorii o alienacji Rahel Jaeggi oraz wcześniejszych definicji tego terminu – m.in. w rozumieniu Marksa – przeanalizowane zostały wybrane utwory, które Włoch wydał od lat 90. ubiegłego stulecia do roku 2018. Książka podzielona jest na pięć rozdziałów, z których pierwszy poświęcony jest podejściu metodologicznemu, drugi recepcji dzieł pisarza w Polsce i na świecie, a ostatnie trzy właściwej analizie tekstów, podzielonych zgodnie z kolejnymi etapami kariery pisarza. Przedstawione badanie dowodzi, iż Nove ukazuje współczesne społeczeństwo jako wyalienowane w dobie mass-mediów oraz postępującego konsumpcjonizmu. Taki stan rzeczy przejawia się nie tylko w treści jego utworów, ale i poprzez ich formę oraz konstrukcję postaci. W ostatniej fazie swojej twórczości autor, mimo pesymistycznej wizji dzisiejszego świata, podaje możliwe remedium na stan wyalienowania człowieka. Odwołuje się w tym celu do poszukiwania przez niego transcendencji w celu nawiązania relacji ze sobą i ze światem (także tym ponadmaterialnym), co z kolei sprawia, że jego teksty mogą wpisywać się w kanon literatury post-sekularnej.

Biodegradable electronics have revolutionized the field of medical devices by offering inherent advantages such as natural disintegration after a useful functional period, thereby eliminating the need for removal surgery. This paradigm shift addresses challenges with long-term implantation, the risks of secondary surgeries, and potential complications, offering a safer and more patient-friendly approach to temporary implantable devices. This review delves into the dissolution kinetics of materials and strategies for lifetime control providing a comprehensive overview of recent advancements in biodegradable electronics. Understanding the kinetics is crucial for meeting the required functional lifetime for implantable medical applications, which varies based on application scope and target diseases. The dissolution kinetics of silicon and biodegradable metals form the core of the discussion, focusing on recent studies aimed at controlling the dissolution rate and enhancing properties. The exploration extends to ideas for accelerating material degradation or initiating on-demand degradation in biodegradable electronics after stable function. Additionally, the compilation of encapsulation layer materials and strategies enhances understanding of how to improve the stable operation time of devices. Emphasis is placed on efforts to adjust the lifetime of biodegradable electronics, particularly in medical applications.

Podocnemis unifilis é a espécie mais abundante do gênero, podendo atingir 50cm de comprimento e pesar até 12,5 kg. As brânquias cloacais compõem o sistema urogenital de quelônios semiaquáticos, desempenhando função de trocas gasosas. Este estudo teve como objetivo descrever aspectos morfológicos, histológicos e morfométricos das brânquias cloacais em espécimes coletados nos rios Tocantins e Javaés. Após a coleta, os espécimes foram submetidos a biometria e eutanásia. O órgão foi fixado e armazenado em álcool até o emblocamento em parafina, microtomia e coloração para microscopia de luz. O software ImageJ foi utilizado para morfometria. Para microscopia de varredura, as amostras passaram por protocolo específico até a fixação em "stubs", produção e análise de imagens. As brânquias cloacais apresentaram quatro camadas (mucosa, submucosa, muscular e serosa), com tecido epitelial estratificado cúbico sobre lâmina própria e tecido muscular liso. A presença abundante de capilares e vasos sanguíneos, sugere que as brânquias desempenham um papel nas trocas gasosas. Espécie do mesmo gênero com habitat diferente apresenta epitélio do tipo simples. Em contrapartida, uma espécie do gênero Phrynops, com habitat semelhante a espécie estudada possui tipo de epitélio igual, evidenciando que o tipo de epitélio das brânquias cloacais varia de acordo com o habitat.

Hospital infection (HI) is a public health problem in Brazil. Resistant bacteria increase the risk of superinfections and raise the number of deaths, factors that may be associated with failures in antiseptic and environmental disinfection processes, favoring cross-contamination. This study investigated the presence of microorganisms on hospital surfaces, on employees' hands and nostrils, and analyzed retrospective infections suspected of hospital infection at a Public Hospital in Palmas, TO. The results revealed the predominant presence of microorganisms of the genus Staphylococcus. The analysis indicated shortcomings in antiseptic and disinfection procedures, highlighting the urgent need for more rigorous biosafety measures. The research emphasizes the importance of appropriate antimicrobial protocols to prevent and treat Healthcare-Associated Infections (HAIs) and underscores the need for awareness and training of healthcare professionals. The study also points to the growing antimicrobial resistance and frequent identification of multidrug-resistant strains. These findings have significant implications for improving patient safety in hospital settings and provide a solid foundation for the development of effective strategies for the prevention and control of nosocomial infections, aiming to reduce the incidence of HI and enhance the quality of healthcare.

O arroz (Oryza sativa L.) constitui-se o alimento básico para cerca de 2,4 bilhões de pessoas, desempenhando importante papel tanto econômico quanto social. Apesar do Tocantins se destacar como terceiro maior produtor, tem potencial de aumentar a produtividade, desde que ocorra o controle eficaz das doenças. Entre as principais, a Mancha-parda se destaca, devido ao fungo Bipolaris oryzae também provocar a mancha dos grãos. Poucos estudos têm relacionado a resistência de cultivares do arroz com os mecanismos bioquímicos de respostas às infecções. Desta forma, o presente trabalho teve por objetivo avaliar a resistência de genótipos de arroz irrigado à mancha-parda e respostas fisiológicas e bioquímicas das plantas. Os resultados obtidos, em campo, por meio da Área Abaixo da Curva de Progresso de Doença (AACPD) e em ambiente controlado, por meio das atividades enzimáticas, demonstraram a variação na resistência à Mancha-parda. Com relação às enzimas mensuradas, houve diferenças entre as plantas inoculadas com B. oryzae e o tratamento testemunha, sem inoculação. Para a enzima Peroxidase de Fenóis (POx), verificou-se que não houve resposta enzimática em relação à infecção por B. oryzae. Por outro lado, para a Quit, houve maior nível enzimático nas plantas infectadas quando comparado às plantas não infectadas.
