[303721] Development and characterization of a system for measuring and analyzing the frequency response of transducers used in the ventilation of neonates and premature infants.
Palestrante: Sara Gomes Mello Santiago
Resumo: Intensive care equipment in premature neonates need specific pulmonary ventilation settings, due to their unique lung compliance and resistance, so as to avoid hyperventilation with large tidal volumes (VT) that can lead to lung injury. Thus, high-frequency ventilation has emerged as a strategy for newborns and preterm infants since it uses a volume below dead space at extremely high frequencies (between 5 and 15 Hz; 300-900 cycles/min), making it possible to obtain higher mean pressures in the airway with minimal volumetric variation in the alveolus. Lung ventilators need to be tested to assess their functioning and essential performance, and in Brazil the ISO IEC 80601-2-12:2020 standard describes the required performance tests with parameter tables for compliance, resistance, tidal volume, respiratory rate and pressure that simulate the ventilation characteristics of a newborn baby. The analysis of the frequency response of the sensors that make up the pulmonary ventilation system is important in the design and development phase of the medical equipment industry, and for this purpose a device that generates a sinusoidal signal for the frequency range of interest in ventilation therapy for premature neonates was developed. This system has a load that simulates the resistance and compliance parameters described in the regulatory standard. The device was characterized in terms of its linearity and frequency response, in order to enable evaluation of the ventilator transducers in respiratory rates, compliance parameters and pulmonary resistances that simulate a premature neonate.

Palestrante: Marcelle Cardoso Sabino de Deus
Resumo: Atualmente, o mercado de gás natural no Brasil tem apresentado expansão devido às
perspectivas de utilização do gás do pré-sal, à venda de ativos da Petrobras e ao estímulo à
entrada de novos agentes, por intermédio de programas governamentais. Simultaneamente,
aumenta o desafio na indústria para manter os parâmetros de segurança das operações. Uma
análise dos resultados de auditorias provenientes da agência reguladora ANP (Agência
Nacional do Petróleo, Gás e Biocombustíveis) possibilitou identificar desvios reincidentes nos
sistemas de gestão de segurança operacional, por parte dos agentes regulados. Neste contexto,
este artigo apresenta o mapeamento dos principais pilares do arcabouço regulatório brasileiro
de segurança operacional, bem como uma proposta de guia (roadmap) para atendimento das
respectivas diretrizes regulatórias. Adicionalmente, é sugerida a utilização dos mecanismos de
avaliação da conformidade já existentes na Infraestrutura Nacional da Qualidade.

[303642] Validação de método de CLAE-EM/EM para determinação de lactose em baixas concentrações em leite em pó a ser aplicado no estudo de viabilidade de um MRC
Palestrante: Raissa Bosich Antunes Jambo
Resumo : Um método confiável e sensível de cromatografia líquida de alta eficiência acoplada à espectrometria de massas em série (CLAE-EM/EM) foi desenvolvido e validado para determinação de lactose em amostras comerciais de leite em pó zero lactose, utilizando a sacarose como padrão interno. O procedimento de preparo das amostras envolveu somente a diluição das amostras de leite em pó no solvente acetonitrila/formiato de amônio (70:30, v/v), utilizando agitação em vórtex para homogeneização e centrifuga para separação. No estudo de seletividade, foi verificado o efeito de matriz para o método, através do teste t para inclinação das curvas, sendo necessário a utilização de curva por adição padrão para a determinação da fração mássica de lactose. O método foi linear (r > 0,99) e homocedástico (aprovado pelo teste de Cochran), dentro da faixa de trabalho (0,1 – 0,8 μg/g). O limite de detecção foi de 130 μg/g e o limite de quantificação foi de 390 μg/g para a amostra em sua forma original, atendendo a legislação brasileira que estabelece o limite permitido de lactose em produtos classificados como isento de lactose. A recuperação variou na faixa entre 97 % e 100 % e a repetibilidade (RSD ≤ 3,7%) foram adequadas para todos os dias de estudo. A precisão intermediária também foi satisfatória, comprovada pelo teste de variância. Os dados de LQ, recuperação e precisão confirmam a aplicabilidade do método proposto para a quantificação da lactose residual.

[305959] Produção de Materiais de Referência Certificados para análises de resíduos em alimentos: soluções de calibração de agrotóxicos
Palestrante: Eliane Cristina Pires do Rego
Resumo: A segurança alimentar é uma grande preocupação mundial e o monitoramento da contaminação de alimentos e rações por resíduos de agrotóxicos é implantando por diversos países, sendo um desafio para a metrologia química e garantia de qualidade. Para garantir a rastreabilidade metrológica nas análises de resíduos de agrotóxicos, devem ser usados Materiais de Referência Certificados (MRCs) de soluções de calibração, que nem sempre estão disponíveis. O uso de soluções certificadas de agrotóxicos traz confiabilidade e comparabilidade para os resultados analíticos. O Inmetro produziu gravimetricamente um lote de lambda-cialotrina em acetronitrila (1267 ± 29 μg.g-1, k=2) e um lote de carbofurano em acetonitrila (1298 ± 32 μg.g-1, k=2) e realizou estudos de caracterização, homogeneidade e estabilidade, disponibilizando os dois primeiros MRCs de agrotóxicos em solução produzidos no Brasil.
[306138] Development of Certified Reference Material of methamphetamine hydrochloride
Palestrante: Silvia Regina Pinheiro Lopes
Resumo: The Bovine Viral Diarrhea Virus is responsible for causing infection of great importance in cattle, being highly disseminated in the world and endemic in Brazil. This virus is also described as the main contaminating virus of Fetal Bovine Serum (FBS), a supplement routinely used in cell cultures and which can become a source of contamination for these cells. Qualitative methods for detecting BVDV RNA can be used both for the diagnosis of the disease in animals and to detect the infection of cultures. In this study, we compared the results of a commercial diagnostic method by Real Time RT-PCR (RT-qPCR) to the RT-Droplet Digital PCR (RT-ddPCR) method using the same set of probe and primers. Serial dilutions of the BVDV RNA standard from the commercial kit and also the BVDV RNA produced in MDBK cells were evaluated by both methods. RT-qPCR showed 100% sensitivity and 80% to 83% specificity compared to the RT-ddPCR method. Points of disagreement between the two techniques arose at low RNA concentrations.

[306913] Preliminary results of ultrasonic output at different applied contact forces to the transducer
Palestrante: Alex Justen Teixeira
Resumo: Ultrasound is a powerful tool for medical and industrial applications. However, with the new opportunities of Industry 4.0, it is natural that measurement protocols become increasingly robust. In contact ultrasound measurements, no studies were identified that systematically evaluated the effect of the transducer contact force on the ultrasonic properties. Therefore, this work aims to study the state of the art of this problem and present a measurement protocol in which it is planned to evaluate the ultrasonic behaviour under different contact forces experimentally. The quantities of interest will be the ultrasonic velocity and the relative amplitude of the propagation signal. Three carbon steel samples were selected for the evaluation planned in this preliminary study. This material was chosen mainly because of its low roughness, which should mean greater control over variations in said properties. For these measurements, the pulse-echo method, with a 5 MHz central frequency transducer, was used to evaluate the amplitudes of the three first reflections and the longitudinal velocity measured from the transit times of the amplitude peaks of the referred reflections. The results of this study will indicate that the increase in the contact force improves the coupling conditions, increasing the amplitude of the ultrasonic signal available to the system. Regarding propagation time, no changes in propagation speed were identified.

[306915] Metrological approach for Poisson modulus measurement of aluminium samples from longitudinal and transverse ultrasonic velocities
Palestrante: Ericles William Jesus dos Santos
Resumo: Destructive tests are widely used in the industry to determine the mechanical
properties of materials. However, usually, they are time-consuming, expensive, and can cause
damage to the materials. In this context, nondestructive ultrasound tests emerge as a viable
alternative to determine mechanical properties without harming the material. The main objective
of this study was to determine the Poisson coefficient of aluminium samples using nondestructive
ultrasound testing. Additionally, a metrological approach was implemented to assess the
quantities, and their respective measurement uncertainty was presented, showing a high
confidence level in the results. The study also highlighted the economic viability of
nondestructive ultrasound testing, as it does not cause damage to the materials and allows for the
evaluation of multiple mechanical properties in a single test, saving time and resources.
Furthermore, the test contributes to quality control in the manufacturing and service of materials
by detecting flaws and variations in their mechanical properties. In this work, Poisson modulus
was determined as 0.3488 and associated with a measurement uncertainty of 0.0133. The results
demonstrated that the Poisson modulus determined in this work, following resources ultrasound
test, was consistent with literature data and technical standards. Therefore, it is reinforced that
nondestructive ultrasound testing is reliable, safe, and efficient in characterising the Poisson
modulus, providing compliance and safety in using materials.

[306923] Estimation of the dynamic modulus of elasticity of concrete using contact ultrasonic and impulse excitation methods.
Palestrante: Aline Marçal da Rocha
Resumo: It is extremely important to know the mechanical resistance to compression of concrete, precisely because it is related to the safety, quality, and durability of structures. However, when designers find themselves in a modeling stage of a structure, knowledge of the modulus of elasticity is essential. In practical terms, it is possible to estimate this property based on pre-established normative values. This practice, although avoiding costly experimental measurements, can lead to oversizing. For this research, this property was obtained and evaluated based on contact ultrasound tests and compared with the results obtained with the excitation method using the Sonelastic® system. To obtain the dynamic modulus of elasticity, the ultrasonic wave propagation test was used for concrete at 14 and 28 days with compressive strength selected to 20 MPa, 30 MPa, 40 MPa, and 50 MPa. All four mixes were made with the addition of a super plasticizer additive, which obtained the lowest water/cement ratio and dosages according to ABNT NBR 6118:2014 Concreto Armado – Procedimento. A set of 84 samples of cylindrical concrete specimens 100mm in diameter and 20mm in height were cast. The measurements allowed establishing comparisons among themselves between the selected acoustic methods for estimating the dynamic modulus of elasticity, as well as comparing with results of static modulus of elasticity established in ABNT NBR 6118:2014.

[303657] Trustworthiness of subsea assets degradation model estimations and its influence on the reliability of risk-based decisions
Palestrante: A L M de Oliveira
Resumo: Although subsea assets in the oil and gas (O&G) industry are very robust equipment, the consequences of their failures may be catastrophic for people, environment and companies.
Nevertheless, the inspection procedures comprise measurement in loco with ROVs, which involve a high resource allocation in costs and planning. For this reason, O&G industries have been pushing a massive investment in digital technologies, like digital twins, with important
simulation tools to estimate and predict the behavior of a process or the conditions of an asset.
Digital twins for integrity management lay on several degradation models, the most relevant ones which subsea assets undergo, such as erosion and corrosion. In this context, the decision
to inspect (or not) is driven by the outcomes from these degradation models, which are always a compromise between resource allocation and the risk associated with a catastrophic failure. It
is called risk based inspection (RBI). This work aims to analyze how uncertainties related to the modeling process can influence the model outcomes and hence the reliability of the
decisions based on them.

[306121] Evaluation of impact energy absorption in natural fiber composites
Palestrante: Tatiana Barbosa de Andrade
Resumo: In response to the increasing concerns about motorcyclists’ safety and advancements in the motorcycle industry, this study investigated the potential of natural fibers as a sustainable means to enhance helmet protection. Leveraging statistical tools such as the Shapiro-Wilk test, Chauvenet’s criterion, and the Interquartile Range, we compared the impact energy absorption of composites reinforced with natural fibers to that of expanded polyurethane (PU) prototypes.
The results, assessed through confidence intervals, indicated that composites reinforced with 5 % sugarcane bagasse, 5 % and 10 % coconut, and 10 % and 15 % sisal demonstrated a notably superior impact absorption performance than pure PU. These insights emphasize the potential of natural fibers in enhancing helmet safety and suggest promising directions for future research into the ideal composite materials for motorcycle helmets a line of inquiry currently in progress.

Resumo: A riqueza de informação contida num resultado de medição completo, expresso pela distribuição de probabilidade do mensurando, é comumente negligenciada em inspeções de recebimento por amostragem e inspeções retificadoras. Dessa forma, a desconsideração da incerteza de medição nas inspeções impossibilita a otimização da configuração de uma inspeção segundo as perspectivas da gestão da qualidade e da produção. Este trabalho propõe o uso e ilustra a aplicação da análise de risco na avaliação da conformidade como ferramenta quantitativa para delineamento da configuração de inspeções retificadoras, considerando, conjuntamente, a incerteza de medição e outros fatores que impactam a eficácia da inspeção retificadora e a produção de itens inspecionados.

[303400] Influence of measurement uncertainty of associated quantities on the uncertainty of liquefied petroleum gas mass in a dynamic measurement system
Palestrante: Gustavo Pessanha Alvim
Resumo: Liquefied Petroleum Gas (LPG) is a versatile and widely used fuel that is crucial in various sectors. Its significance as a combustible gas stem from its high energy content and ease of storage and
transportation. Its lower environmental impact than other fossil fuels further enhance its appeal as a cleaner energy alternative. This fuel finds extensive applications in industries, commercial establishments, and agricultural activities, which sheds light on its measurement systems. Based on the calculation algorithms for LPG mass, which is the trading unit of the product, and the regulatory ordinance, this study aimed to evaluate the critical factors that impact the calculation of the mass
measurement in a dynamic measuring system. This work introduces the measurement function for mass calculation and the associated uncertainty calculation. Furthermore, it presents the concept and
functioning of a measuring system, along with the critical factors and associated quantities, which significantly impact the calculation of the expanded uncertainty of LPG mass: correction factors for the
effects of pressure, density, and temperature. Approximately, these factors have, respectively, the following weights in the total uncertainty value, based on the arithmetic average of the conducted
experiments: 45 %, 43 % and 9 %. The study concludes that the prescribed uncertainty limits established by the Brazilian Institute of Metrology, Quality, and Technology regulations for secondary (or
associated) quantities have limited practical significance. It occurs because all indications suggest that the uncertainty values exceeding the prescribed limit for individual uncertainty can still meet the
maximum uncertainty of the output variable – LPG mass – which is the crucial aspect. Lastly, a future study to optimize individual acceptance criteria calibration is proposed.

[297351] Attitude toward online privacy of Brazilian users with a focus on the Metrology community
Palestrante: Vinicius Coutinho de Oliveira
Resumo: As Industry 4.0 comes into reality, Metrology must evolve with it. The digital transformation in Metrology implies data transport instead of measuring instrument transport. Hence, massive amounts of data will be exchanged between calibration laboratories and client facilities, where the measuring devices are placed. Since sharing data poses risks, controls are necessary to protect information assets. Nevertheless, the human element is often the weakest link in the Information Security chain and deserves attention. This study evaluates the attitude toward privacy of Brazilian internet users with a focus on the Metrology community by surveying 324 respondents to assess their attitudes, worries, and perception of privacy, the use of privacy tools, and the susceptibility to providing data through a simple social experiment. Data analyses consisted of descriptive statistics and hypotheses testing. Results do not indicate differences between the Metrology and the general public groups. Users are aware of online threats, but this awareness needs to translate into actions to increase privacy. Such actions, in turn, depend on user training. This paper points out the privacy tools less used – whose adoption should be encouraged – and brings recommendations for the digital transformation in Metrology to take place in compliance with basic data protection requirements.

Resumo: This work presents an educational web application about dimensions and properties related to nanomaterials. The application brings information through a simulated experience with the presentation of nanomaterials images in 2D, 1D and 0D formats. Comparisons between objects of different sizes are also made, allowing to approach the basic notions of metrology, such as magnitudes and scales. As an educational resource, it helps in learning and discovering the properties and applications of nanomaterials related to the change of scale and its consequences in an interactive way. The scope was limited to carbon nanomaterials in order to meet the objectives more efficiently. The validation was done using the inverted classroom model with a post-high school technical course class. The validation process showed that the application, besides serving as an educational resource for high school classes, can be extended to several classes or even to the general public, and is also suitable for learning methodologies that incorporate new technologies.
