[297590] The Challenge of Developing Certified Reference Materials of Carbon Dioxide to Establish Traceability to Greenhouse Gases Monitoring Analysis
Autores: Andreia de Lima Fioravante, Claudia Cipriano Ribeiro, Viviane Fernandes Mello, Cristiane Rodrigues Augusto Chelles Iglesias, Valnei Smarçaro da Cunha
Resumo: In recent years the need for the quality control, reliability and traceability of analytical results has been strongly emphasised. The increase in the concentration of carbon dioxide (CO2) in the atmosphere has led the scientific community to investigate the adverse effects on humanity and nature, including the greenhouse effect, which contributes to global warming and can lead to climate change, besides the risks associated with human health. Due to the importance of metrological issues in the current scenario, the Laboratory of Gas Analysis (Lanag) of the National Institute of Metrology, Quality and Technology (Inmetro), is involved in improving measurement capabilities to provide confidence level regarding greenhouse gases standards by developing the methodology of preparation of such primary standard gas mixtures through gravimetry. This paper describes the development of certified reference materials of carbon dioxide in atmospheric synthetic air that are used to monitor its concentration in the atmosphere. Considering the contributions from gravimetry preparation and its verification analysis by cavity ringdown spectroscopy (CRDS) the relative expanded uncertainty of the standard mixture of carbon dioxide was lower than 0.5 % for the range studied from 370 to 550 μmol/mol, which is comparable to the average of 0.25% relative uncertainties presented on international standards mixtures.

[303386] Quantitative analysis of biodiesel in diesel fuel by UV-Vis spectroscopy
Autores: Simone de Britto, Erlon Henrique Martins Ferreira, Oleksii Kuznetsov
Resumo: A preliminary methodology for determination of biodiesel content in commercial diesel fuel by ultraviolet and visible absorption spectroscopy (UV-Vis) was developed seeking its potential application in optical sensors for monitoring the diesel/biodiesel mixtures in heavy vehicles. Absorbance of visible light between 400 nm and 500 nm showed a linear response of the optical signal as a function of the biodiesel content for the investigated volume concentration range of biodiesel varying from 0 % to 20 %. Multivariate analysis was used to validate the construction of different calibration curves, differentiated by feedstocks origins for the starting pure biodiesel and diesel components, and determine the optimal wavenumber to perform ordinary linear regression. A narrow range of the visible spectrum around 450 nm provided the best coefficient of correlation for all calibration curves. The effects of the supplier of base biodiesel and diesel components used to make the calibration curves on the predictions of the singlevariate model was also assessed.

[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
Autores: Raissa Bosich Antunes Jambo, Rodrigo Vivarelli Poggi Leal, Eliane Cristina Pires do Rego, Jhenifer Marques da Silva, Vanderléa de Souza
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.

[305909] Comparison of RT-qPCR and RT-ddPCR methodologies for the detection of Bovine Viral Diarrhea Virus (BVDV) RNA
Autores: Ariane de Mesquita Rodrigues, Aurea Valadares Folgueras Flatschart, Roberto Becht Flatschart, Mayane Ribeiro de Faria Henrique, José Lafaiete Palles Ramos Júnior
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.

Autores: Eliane Cristina Pires do Rego, Rodrigo Vivarelli Poggi Leal, Jane Luiza Nogueira Fernandes, Wagner Wollinger, Bruno Carius Garrido, Janaína Marques Rodrigues
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
Autores: Silvia Regina Pinheiro Lopes, Wagner Wollinger, Eliane Cristina Pires do Rego, Bruno Carius Garrido
Resumo: This work aimed to present the production of certified reference material (CRM) of methamphetamine hydrochloride, as an important tool to ensure the quality of forensic results. Methamphetamine is a synthetic drug derived from amphetamine, which potentially stimulates the central nervous system, and its prolonged use can cause excessive anxiety, euphoria, bipolar disorder, psychosis, among other health damages. To produce this batch of CRM, homogeneity and transport stability studies were carried out by HPLC-PDA using the results of chromatographic area corrected by the mass fraction of the sample in the analyzed solution. Evaluation of stability under storage conditions and characterization of the material were performed by 1H qNMR, a primary measurement procedure. The CRM showed neither considerable heterogeneity nor tendency to instability under transport conditions (temperature of 50 ºC up to 21 days) and storage conditions (20-25 °C). The certified purity value of methamphetamine hydrochloride was (999 ± 12) mg/g, equivalent to a mass fraction of (99.9 ± 1.2) g/100g (k = 2).

[306913] Preliminary results of ultrasonic output at different applied contact forces to the transducer
Autores: Alex Justen Teixeira, Ericles William Jesus Santos, Tiago Costa Dourado, Sandro Aureliano Miqueleti, Rodrigo Pereira Barreto Costa-Félix
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
Autores: Ericles William Jesus dos Santos, Mylena Kathleen Mosqueira de Assis, Alex Justen Teixeira, Tiago Costa Dourado, Sandro Aureliano Miqueleti, Rodrigo Pereira Barretto Costa-Félix
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.

[305898] Metrological evaluation of ultrasonic velocity in oils for commercial phantom development
Autores: Mylena Kathleen Mosqueira de Assis, Rodrigo Pereira Barretto da Costa Félix
Resumo: This study focuses on the metrological evaluation of ultrasonic velocity in materials to develop Tissue Mimicking Materials (TMM). TMMs are essential for assessing ultrasound equipment performance, safety, technical assessment, and studying the biological effects of ultrasound. Agar-based TMMs are commonly used but have limited durability, necessitating the development of commercially viable alternatives. Oil-based TMMs, such as mineral and lubricating, show promise due to their stability and favourable characteristics. The study aims to characterize the ultrasonic properties of oil-based materials, aiming to produce a stable TMM suitable for the transportation and evaluation of ultrasound diagnostic equipment. The results for each material were as follows: ethylene glycol (1727.0 + 4.6) m s-1, mineral oil (1397.0 + 5.7) m s-1, and lubricating oil (1472.0 + 4.7) m s-1. Thus, mineral oil and lubricating oil are the most suitable materials.

[306923] Estimation of the dynamic modulus of elasticity of concrete using contact ultrasonic and impulse excitation methods
Autores: Aline Marçal da Rocha, Ericles William Jesus Santos, Alex Justen Teixeira, Tiago Costa Dourado, Sandro Aureliano Miqueleti, Robson Luis Gaiofatto, Rodrigo Pereira Barretto Costa-Félix
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.

[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
Autores: Sara Gomes Mello Santiago, Davi Giordano Valerio, João Henrique Angelo, Roberto Romano, Henrique Takachi Moriya
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, highfrequency 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 80601-212:2020 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.

[306375] Monitoring and evaluation of regulation on pesticide labelling and packaging leaflets in Brazil: a conceptual model and indicators
Autores: Maria Fatima Ludovico de Almeida, Jessica Peres Medeiros
Resumo: Pesticide labelling and packaging leaflets are essential communication instruments between pesticide companies, health professionals, regulatory agencies, farmers, and consumers within the agri-food chain. This paper presents a conceptual model for ranking indicators to monitor and evaluate the outcomes of the current regulation on pesticide and wood preservative labelling and packaging leaflets in Brazil. The model applied to the Resolution of the Collegiate Board – RDC 296/2019, published by the National Health Surveillance Agency (Anvisa) in Brazil, could effectively demonstrate its adequacy and usefulness to help the Agency to monitor and evaluate label and packaging leaflet compliance with the regulatory framework on a national scale. The main results can be summarized as follows: (i) a fuzzy multicriteria tool for ranking indicators associated with the categories of legal requirements of the RDC 296/2019; and (iii) a set of 69 indicators ranked by these categories to be subsequently selected by the Agency.

Autores: Marcelle Cardoso Sabino de Deus, Edisio Alves de Aguiar Junior
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.

[303836] Ultrasonic characterisation of soybean biodiesel produced from different molar ratios
Autores: Pâmella de Assunção Oliveira, Raphaela de Melo Baesso, Rodrigo Pereira Barretto Costa-Félix
Resumo: The ultrasonic characterisation of soybean biodiesel produced from different alcohols and molar ratios was performed at 1 MHz. The measurement of the speed of sound of the biodiesel samples was performed using the pulse-echo technique. It was possible to observe that samples of biodiesel produced from different alcohols under the same molar ratio present a nonequivalent speed of sound. Samples produced at a molar ratio of 6:1 have the lowest speed of sound. The ultrasound could differentiate the biodiesel samples evaluated through the speed of sound parameter.

[304912] Gasoline composition monitoring using ultrasonics
Autores: Iris Trindade Chacon, Eving da Silva, Mylena Kathleen Assis, Rodrigo Pereira Barretto da Costa-Felix
Resumo: Monitoring the adulteration of fuels is a matter of interest as a means of protecting consumers, preventing fraud and protecting the environment. In Brazil, commercialized gasoline is a mixture of fuel with 27% anhydrous ethanol, called C gasoline. As a misleading practice, larger fractions of ethanol and organic solvents are used. Laboratory analyses are necessary to detect this irregularity, making inspection actions more difficult. Given the above, the article proposes using ultrasound to identify gasoline adulteration as an alternative method. Different samples were used: pure gasoline, gasoline with ethanol prepared for the study (gasoline C) and mixtures with kerosene. The study was based on measuring two monitoring parameters: propagation velocity and experimental attenuation. Ultrasound transducers with central frequencies 1 MHz and 5 MHz were used in the pulse-echo method. Paired comparisons (t-tests) were performed to assess whether the use of ultrasound was sensitive to changes in the medium with the addition of solvent. The experimental attenuation showed a statistical difference compared to gasoline without kerosene, proving to be a good parameter to be monitored. For the propagation speed, only the samples with 20% and 30% of kerosene and with the 1 MHz transducer proved adequate to the proposed method.

[303657] Trustworthiness of subsea assets degradation model estimations and its influence on the reliability of risk-based decisions
Autores: M B Demay, A L M de Oliveira, G. Pauli, G Donatelli, P H Z Machado
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
Autores: Tatiana Barbosa de Andrade, Rosana Medeiros Moreira, Edilvando Pereira Eufrazio, Tatiana Vianna Francisco, Elcio Cruz de Oliveira
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.

[306377] Análise de risco para avaliação de inspeções de retificação: Uma ferramenta quantitativa para gestão da qualidade industrial
Autores: Ricardo Luís d’Avila Villela
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.

[295440] Conformity assessment applied to custody transfer in the oil and gas industry: a brief review
Autores: Guilherme Lucarelli Orsay, Khrissy Aracélly Reis Medeiros, Elcio Cruz de Oliveira
Resumo: In the oil and gas industry, measurements must be highly reliable to avoid unnecessary conflicts in business relationships that could result in significant financial losses for the parties involved. This article highlighted the importance of using the measurement uncertainty tool for conformity assessment purposes in the oil and gas industry. Some methodological approaches and considerations within the context of conformity assessment were presented, such as the Bayesian theory of probability, global and specific risks, producer and consumer risks and the use of the guard band tool. Based on a literature review, it was observed that measurement uncertainty is widely applied in conformity assessment in various industries, such as pharmaceuticals, materials engineering, production, and quality engineering, as well as laboratory analysis. However, it was found that none of the reviewed studies proposed or used the measurement uncertainty tool to minimize the risk of false conformity assessments in the transfer of petroleum and its derivatives by producers and consumers. Therefore, it is considered that this tool can also be an excellent alternative to minimize the risks of inadequate compliance during custody transfer operations in the oil and gas industry. As a main contribution, we sought to highlight the relevance of the guard bands tool as a methodological resource in the treatment of data from oil and gas industry processes that require conformity assessment. Finally, it was concluded that the implementation of this approach can reduce risks and help in decision-making related to compliance assessments, ultimately avoiding significant losses for the parties involved.

[304580] Study of the feasibility of measuring vehicular natural gas (CNG) in Brazil by Equivalent Liter of Gasoline (ELG) or Equivalent Liter of Ethanol (ELE)
Autores: Regina Cássia Mattos de Paula, Edísio Alves de Aguiar Júnior, Janaína Tavares Goulart de Sá Belchior de Oliveira
Resumo: The natural gas used in Brazil is formed by a chain of hydrocarbons, mainly methane, in addition to gases in smaller proportions, such as ethane, propane, carbon dioxide, and nitrogen. It is a fossil fuel discovered in porous rocks derived from the organic matter of prehistoric animals and plants. The US calls natural gas shale gas. Its origin is from fossil residues identified in rocks with reduced porosity and permeability. The shale gas extraction method differs from the NG obtained in Brazil. CNG is measured in Brazil in volume (m3) and the US in Gallons of Gasoline Equivalent (GEG). The study points out measurement inconsistencies of CNG per volume (m3) and mathematics relates the amount paid in Reais for 1 m3 of CNG, in mass (kg), Gasoline Liter Equivalent (GLE), and Ethanol Liter Equivalent (ELE). Studies present an unreliable CNG measure in GLE or ELE and volume (m3) and recommend measuring CNG in mass (kg), in Brazil.

[303756] Dilemmas in the clinical investigation of clinical electrical thermometers in relation to the measurement method
Autores: Célio Henrique de Mattos Fraga, Rodrigo Freitas Guilherme, Rafael Feldmann Farias, Flávio Willians Sant’Ana
Resumo: The clinical electrical thermometer (CET) is a measuring instrument in the health area, with metrological technical regulation approved by Inmetro Ordinance No. 325 of July 28, 2021 (MTR No. 325/21). According to this regulation, there are two types of CET’s, depending on the algorithm of the manufactured model: non-predicting (thermal equilibrium) and predicting (calculating), with three possible application sites on the body: axilla, mouth (sublingual) and rectum. The type approval applicants of almost all models submitted for type evaluation were declared non-predicting. Still, while evaluating some of these models, the clinical tests submitted corresponded with the predictive method. Additionally, the aggravating factor is that the results of these clinical tests did not comply with the regulation, as the indication varied by more than 0.2°C between the moment of the alarms and after 5 minutes in most measurements.
Nonetheless, since are analyzed the clinical tests in a preliminary phase, allowing for document correction, the applicants submitted other clinical tests in the required format for non-predicting. For this measuring method, variations in CET indication are not required after finishing measurement alarms by the regulation, assuming they do not occur due to the thermometer being non-predicting. Consequently, the evaluation process could proceed normally, even with technical doubts about the actual measurement method and the understanding that the operation was inconsistent with the declared method. For a better understanding, we reviewed the literature on the physics of thermometers and human body physiology, a documentary analysis of previously approved models, and the requirements of MTR No. 325/21 to seek possible explanations for these occurrences. As a result, the need for improvements in this regulation was identified, and some changes in the type of evaluation procedures have already been implemented.

[303400] Influence of measurement uncertainty of associated quantities on the uncertainty of liquefied petroleum gas mass in a dynamic measurement system
Autores: Gustavo Pessanha Alvim, Elcio Cruz de Olveira
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.

[306256] Electrical characterization and modeling of PVDF thin-film for application in piezoelectric energy harvesting
Autores: Laís dos Santos Gonçalves, Maria Clara Morais, Khrissy Aracélly Reis Medeiros, Carlos Roberto Hall Barbosa
Resumo: Based on the necessity for cleaner and renewable energy and the growing global demand, energy harvesting stands out increasingly in this scenario. This technique is notable for the possibility of converting some types of energy that are generally neglected into electrical energy that can be used to power low-consumption electronic devices. In this context, piezoelectric materials demonstrate excellent applicability due to their ability to convert kinetic energy into electrical energy. Although these concepts and principles of conversion have been known for a long time, their use has increasingly grown in recent years. Thus, the present work objectively focuses on the electrical characterization of a thin-film piezoelectric sensor of Polyvinylidene Fluoride (PVDF) and a computational modeling of its behavior in LTSpice® software as a preliminary step of a study aimed at the development of a piezoelectric energy harvester (PEH). Consequently, this work allows for identifying and analyzing the intrinsic needs of the project, contributing to the optimization of the PEH performance.

[303021] The key role of metrology laboratories in shaping the future
Autores: João Alves e Sousa, Álvaro Silva Ribeiro, Carlos Pires, Luís Ribeiro
Resumo: Europe aims to maintain its leading role as a sustainable, fair, and competitive advanced economy embracing a swift and inclusive transition towards environmentally sustainable lifestyles and economies. A Green and Digital transition is being envisaged to keep the planet liveable and seize economic opportunities, where digital technologies will play a crucial role in achieving climate neutrality and reducing pollution, by measuring and controlling inputs with increased automation. Also, increased connectivity and integration provided by the internet of things, smart systems and smart cities, requires strengthen the flexibility of systems and networks, and new products, services and businesses. Thus, the need to have measurement in the centre of the process of green and digital transition is obvious, to ensure safety and quality for products traceability, requiring standards and conformity assessment, enhancing the pillars of the quality infrastructure where metrology, testing and inspection laboratories are key. In Metrology, data acquisition and treatment will remain as core activities to ensure the quality and validity of results, but larger volumes of data have a potential that is not available using common software tools, so that Artificial Intelligence tools and calibration through machine-readable harmonized digital formats are critical to cope with the new metrology ecosystem.

[297351] Attitude toward online privacy of Brazilian users with a focus on the Metrology community
Autores: 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.
