Property requirements of vibration measurements in wind turbine drivetrain bearing condition monitoring
Authors: Strömbergsson D , Marklund P , Berglund K , Larsson P-E
Published: November 2021

Wind turbine drivetrain bearing failures continue to lead to high costs resulting from turbine downtime and maintenance. As the standardised tool to best avoid downtime is online vibration condition monitoring, a lot of research into improving the signal analysis tools of the vibration
measurements is currently being performed. However, failures in the main bearing and planetary gears are still going undetected in large numbers. The available field data is limited when it comes to the properties of the stored measurements. Generally, the measurement time and the covered
frequency range of the stored measurements are limited compared to the data used in real-time monitoring. Therefore, it is not possible to either reproduce the monitoring or to evaluate new tools developed through research for signal analysis and diagnosis using the readily available field
data. This study utilises 12 bearing failures from wind turbine condition monitoring systems to evaluate and make recommendations concerning the optimal properties in terms of measurement time and frequency range the stored measurements should have. The results show that the regularly stored
vibration measurements that are available today are, throughout most of the drivetrain, not optimal for research-driven postfailure investigations. Therefore, the storage of longer measurements covering a wider frequency range needs to begin, while researchers need to demand this kind of data.

Las limitaciones impuestas por el COVID 19 afectaron negativamente al desarrollo de las asignaturas de carácter práctico, en este caso la expresión musical, por lo que fue necesario buscar alternativas tecnológicas que permitieran la realización de actividades musicales colectivas. Esta experiencia se inició en el itinerario de Música del Máster universitario en profesorado de educación secundaria obligatoria, bachillerato, formación profesional y enseñanza de idiomas, dentro de la materia Proyectos de Innovación e Investigación Educativa en Música, siendo la primera vez que este itinerario se impartía en la UDC. Con el confinamiento, el trabajo final tomó forma de concierto, para demostrar que, aún desde el aislamiento, el aula de música seguía trabajando. A medida que el proyecto se conformaba, se fueron incorporando estudiantes de doctorado, que llevan varios años haciendo de mentores de alumnado de Música del Máster en Didácticas Específicas, así como el alumnado de Grado. El primer reto fue la ejecución de una obra orquestal estando cada intérprete en su domicilio. Para garantizar el cumplimiento del objetivo general, se estableció un organigrama y un cronograma con los repartos de roles y las diferentes fases de realización. Independientemente de algunas dificultades técnicas inevitables, los resultados superaron las expectativas iniciales, al recibir el reconocimiento de la comunidad universitaria, de la prensa y de los medios de comunicación.

Published: November 2021

Three-dimensional (3D) bioprinting has become a promising strategy for bone manufacturing, with excellent control over geometry and microarchitectures of the scaffolds. The bioprinting ink for bone and cartilage engineering has thus become the key to developing 3D constructs for bone and cartilage defect repair. Maintaining the balance of cellular viability, drugs or cytokines’ function, and mechanical integrity is critical for constructing 3D bone and/or cartilage scaffolds. Photo-crosslinkable hydrogel is one of the most promising materials in tissue engineering; it can respond to light and induce structural or morphological transition. The biocompatibility, easy fabrication, as well as controllable mechanical and degradation properties of photo-crosslinkable hydrogel can meet various requirements of the bone and cartilage scaffolds, which enable it to serve as an effective bio-ink for 3D bioprinting. Here, in this review, we first introduce commonly used photo-crosslinkable hydrogel materials and additives (such as nanomaterials, functional cells, and drugs/cytokine), and then discuss the applications of the 3D bioprinted photo-crosslinkable hydrogel scaffolds for bone and cartilage engineering. Finally, we conclude the review with future perspectives about the development of 3D bioprinting photo-crosslinkable hydrogels in bone and cartilage engineering.

The development of the Person-Centered Approach was divided into phases that presents the attitudes that are part of therapeutic relationship, regardless of the public served. However, in the specificity of child psychotherapy, the theoretical and practical development of the approach points to the existence of peculiarities. This study aims to present, through narrative literature review, based on Gadamer's philosophical hermeneutics, the possible characteristics related to the child therapy, starting from a return to the PCA phases. We discuss the foundations of child therapy in Rogers and Axline's classic perspective, understanding how child play therapy is characterized in non-directive, reflective, experiential and post-Rogerian phases. We discuss contemporary proposals in the European, American, and Brazilian contexts. We conclude that this delimitation enables a clearer perception of changes and improvements amongst to the Rogers and Axline's pioneering work, always having as its axis the relational dimension and the tendency to growth as a motor of the therapeutic process.

This study aimed to investigate the contributions of Phenomenology to Health Psychology based on Brazilian academic production. A search in the SciELO (Scientific Electronic Library Online), PePSIC (Electronic Psychology Journals) and LILACS (Latin American and Caribbean Health Sciences Literature) databases was performed and thirteen papers published between 2000 and 2018 were selected and analyzed. It was found that Phenomenology contributes in many ways while Edmund Husserl's epistemology, as well as an approach that presents a view of the world and human beings by means of a number of phenomenologists, and as a philosophical phenomenological method adapted to Psychology by various authors. As far as Health Psychology is concerned, research brings an understanding of the health-disease-care process both by the analysis of the experiences of users who turn to health services as well as by professional psychologists' practice within a biopsychosocial perspective. A plurality of theoretical conceptions and methodological pathways is observed both when it comes to Phenomenology and Health Psychology, thus further studies on Health Psychology stemming from the contributions of Phenomenology are promising.

The main feature of the nearest 5-km zone of the Chernobyl nuclear power plant is the maximum concentration of fuel fallouts due to the accident in 1986. It is a unique testing ground for radiobiological research in the natural habitat of animals. At present, the background radiation level in the 5-km zone of the Chernobyl nuclear power plant fluctuates from 0.1 to 20 μSv/h. Besides, electrons from the decay of 90Sr and 137Cs add a significant contribution to the radiation background. Even though a large amount of experimental data on dose loads on the fauna of affected areas has been accumulated to date, the results obtained do not give an unambiguous idea of the dose dependences of radiobiological effects in natural ecosystems. In this work, we studied the total dose of irradiation of two murine rodents species: the bank vole (Clethrionomys glareolus) and the yellow-necked mouse (Apodemus flavicollis), living in territories of different levels of pollution near the destroyed power unit 4 of the Chernobyl nuclear power plant. We have assessed the density of radioactive contamination of the territory and study the isotopic composition of the fallout. Soil samples were taken to a depth of 30 cm, considering the depth of burrowing of mouse-like burrows is 10-15 cm. The 90Sr, 90Y, and 137Cs concentrations were measured using β- and γ-spectrometric methods for the selected soil samples. The 90Sr, 90Y, and 137Cs βactivity spectra were measured using a developed scintillation beta-spectrometer with a thin entrance window. Soil samples' gamma spectrometric studies were carried out using an anti-Compton device with an HPGe detector. The method for processing complex Xray and gamma-spectra in the energy range of 10-100 keV is developed. It takes into account the complexity of describing X-ray lines and providing a processing error of ≤1%. We calculated the murine rodents' radiation doses using the obtained data on the concentration of 90Sr, 90Y, and 137Cs activities in soil samples and animal bodies. The doses were calculated due to external irradiation with γ-quanta and electrons and internal irradiation with 137Cs and 90Sr electrons. For the first time, we obtained data on external electrons' contribution to the total dose of irradiation of murine rodents living in the contaminated territories of the 5-km zone of the Chernobyl nuclear power plant. Doses of internal irradiation and external γ-quanta are in good agreement with the data obtained for these territories earlier. It was found that the radiation dose is formed mainly due to external electrons for most rodents. Since many studies, including genetic and biochemical ones, are tied to the radiation dose, the correct account of the contribution of electrons to the radiation dose is, in many cases, critical.

In a number of industrialized regions of the Russian Federation, even when using efficient high technologies in the manufacturing industry under the current linear economic model, especially in the context of pandemic (COVID-19) fails to implement the sustainable development goals in all of its ecological and economic requirements. This paper analyzes models and approaches to the implementation of the concept of renewable production and consumption in conditions of maximum use of resources, including those obtained by processing various types of waste. According to the analyzed one of the models, namely the circulation economic model, resources after consumption in the form of manufactured products and the resulting waste, suitable for processing into production resources, in the form of secondary. Within the framework of rational interaction of the industrially developed regions (Moscow and Kaluga), an experimental confirmation of the efficiency of waste processing of various types is given, by building an Ecotechnopark, implemented within the framework of public-private partnership, and obtaining secondary products. In the proposed circular economic model, resources after consumption in the form of production products are returned to production after processing. In addition, a possible indicator was identified and implemented that allows integrating traditional economic indicators into the "Green" gross national product (GNP), which is the sum of the natural capital of the region and its nominal GNP and is linked to the state of the ecosystem. Recommendations and conclusions on the performed studies are made.

Published: November 2021

The existing radar and radio navigation facilities sometimes do not satisfy the increased requirements for the accuracy, efficiency and reliability of information support for navigation in the organization of movement in the rough waters of the Arctic region in difficult climatic and meteorological conditions. This article offers a comprehensive approach to the information support of navigation based on technical solutions that significantly increase the capabilities of navigation tools in the rough waters of the Arctic zone. The proposed approach to the creation of fundamentally new high-precision information tools for solving a wide range of new tasks in the Arctic zone based on radar provides a higher class of accuracy and functionality compared to those currently used. The technical requirements for radar facilities are defined and the use of a new generation of highly informative multifunctional coastal radars in combination with new mobile pilotage terminals is proposed. The application of the proposed technical solutions and the principles of building navigation systems will significantly increase the safety and efficiency of navigation in waters with increased complexity of navigation organization. The proposed approaches will ensure the solution of the such tasks as: monitoring of air, surface and ground space, local navigation system for safe navigation of ships, helicopter flight, landing of helicopters on offshore drilling platforms and ground airfields, mooring of vessels to drilling platforms and terminal berths. It also support monitoring and dispatching of ship traffic in ports and the area of responsibility of terminals, including monitoring the position of ships at anchorage. Will be sufficient simplify high-precision operational assessment of the ice situation and the weather in the radar area of responsibility, protection of offshore drilling platforms and territories of onshore terminals, information support of means of protection against potential terrorist threats.

Published: November 2021

In a significant number of waters with difficult navigation conditions, especially in the waters of the sea and river ports of the Arctic, despite the presence of a wide range of modern information and navigation aids, pilotage is actively used. In some cases, the pilot's situational awareness in difficult meteorological conditions is insufficient, which necessitates the introduction of more advanced information sensors and communication tools. To solve this problem, it is necessary to develop proposals on the principles of building technical means for increasing situational awareness during pilotage in sea and river ports of the Arctic zone of Russia. This article proposes the concept of constructing a system for providing a pilot with additional highly detailed information based on the technology of broadband data transmission of a highly informative port radar station directly to the pilot's terminal with visualization of the real picture of the navigation situation. The application of the proposed principles of building information support systems for pilotage services in ports will improve the efficiency and safety of navigating ships in the port water area and on approaches to the port, increase the rate of information exchange between the control point and the ship's crew (pilot), and create prerequisites for automating ship management processes. The use of a new generation of highly informative radars and mobile terminals associated with them via broadband communication channels ensures the creation of a local navigation system for navigation. That ensures pilotage in the Arctic zone of ships of any type, including those without high-quality ship radars, and provides automation of the assessment of threatening situations and solutions for them prevention even with unstable operation of satellite navigation systems. In essence, this technology is the first step towards increasing the automation of navigation in ports and ship passages.

Among the most significant system properties of such complex technical objects as man-machine complexes, it should be noted the possibility of unauthorized actions of operators or control personnel in subjectively difficult situations. During operation, these properties determine the need to consider the area of potential situations of control of man-machine complexes that were not provided for by the developers during the design.Traditionally, this problem arises at the stage of the operation of the complexes, when situations of the system functioning unforeseen by the developers arise from time to time. Further, they form the basis of projects for the modernization or improvement of this type of equipment. The purpose of this work is to consider the constructive conceptual apparatus, methods of analysis, including formal means of identifying and assessing the functional redundancy of organizational structures of operational management systems and to develop principles for its use to ensure the homeostaticity of group activities of operators in conditions of negative influence of environmental factors. The article systematizes the basic concepts and definitions of homeostasis of group activity of operators of control groups of modern man-machine complexes. On the basis of the set-theoretic model, the conditions for increasing the stability of the activity of a group of operators in conditions of the negative impact of external factors are determined. The set-theoretical analysis of the functionally redundant organizational structure of operational management systems carried out in the article makes it possible to determine the conditions and mechanisms for expanding the area of homeostasis of the functioning of the organizational structures of control systems, the implementation of which is associated with the methods of coordinating and motivational influence on operators, improving the structure of their information and functional interactions and substitutions (emulation) of the functions of the operators of the degrading control group.

Published: November 2021

An increase in the productivity of oil wells is possible with the use of a promising technology based on implosion and a device for its implementation. It is known that the effectiveness of the technology depends on the design parameters of the device. Currently, a promising way to study processes is computer modeling based on modern information technologies. Therefore, solving forecasting problems using modern software based on artificial neural networks (ANNs) is an urgent task of scientific and practical interest. In this regard, the aim of the work is to develop a neural network model and its application to identify the features of the influence of the diameter and length of the implosion chamber of the device on the pressure of a water hammer during implosion. In the software environment, the following have been created and tested: a method for developing a neural network model; a method of conducting a computational experiment with it. The possibility of neural network modeling of the implosion process has been studied. The results of predicting the output parameter, in this case the pressure of the water hammer, on a pre-trained network, with a relative error of 3.5%, using the knowledge base are demonstrated. The results of applying the methodology for solving forecasting problems using software based on artificial neural networks are presented. It was found that the diameter and length of the implosion chamber significantly affect the pressure of the water hammer. The practical significance of the work lies in the ability to determine the required values of the diameter and length of the implosion chamber of the device at a given level of water hammer pressure.

The tasks of grouping, classifying, and clustering data are widely encountered nowadays in different areas of activity. These tasks need to be solved in librarianship and even in social networks. One of the complex and important tasks is a grouping of normative and reference information. Solving this problem will allow us to perform complex operations with the normativereference information: building a hierarchical structure from scratch, adding new entities or groups to the existing, and combining several lists of normative-reference information independently of the original hierarchical structure presence. This article includesdescription of using DBSCAN as an agglomerative-iterative clusterization algorithm. The iterative part of this algorithm is necessary forfull entity list clusterization on every hierarchical level. Clustering metrics such as adjusted Rand index, Jaccard index, Foulkes-Mallows index are considered. A new metric based on the previously mentioned metrics has been proposed. A combination of Word2Vec and TF-IDF algorithms is used to convert the textual names of objects to numerical form.

Authors: Manalu S. Rouli , Muhammad Rafky
Published: November 2021

This research examines how adolescents perceive their memberships and involvement in virtual forums and whether the young generations see this involvement facilitate their engagement with public issues surrounding them. The increase of political discussions and political debates over the Internet and social media in Indonesia has become the trigger of this research to see whether adolescents as the group of new voters, even first-time voters, use virtual forums to be critically engaged in a discussion of public issues. Alternatively, this research would see whether their engagement in virtual communities is mainly related to entertainment, social connections, and other matters not directly related to politics and discussion of public issues. By interviewing a group of adolescents from at least eight provinces in Indonesia, this research examines the phenomenological experiences regarding their action, perception, and evaluation of their involvement through various virtual communities. This research highlights the importance of understanding adolescents’ experiences in virtual communities to understand better their tendency and attitude in relating to issues in their online and offline environments.

The study aimed at assessing the contribution of VUP in poverty reduction especially in Kigabiro sector. This study has general objective which is to assess the contribution of Vision 2020 Umurenge programme on poverty reduction supported by three specific objectives which are to assess the contribution of public works on poverty reduction, to determine the contribution of financial services on poverty reduction, and also to evaluate the contribution of direct support services on poverty reduction especially in Kigabiro sector located in Rwamagana district, Eastern province. Internationally, poverty can describe different things in different part of the world to different people, but it can be defined as when people are not able to afford basic needs. USA has come a long way in addressing the problem, but progress seems to have slowed despite the recent years of economic recovery.  In Africa, hundred millions of people in the poorer countries are worries only with survival and elementary needs and average poverty rate for sub-Saharan Africa stands at about 41 percent, and of the world’s 28 poorest countries, 27 are in sub-Saharan Africa all with a poverty rate above 30 percent. Referring to Rwanda, because may people in Rwanda live in rural area, they also live-in poverty line which is so hard for GoR to answer each Rwandan’s problem but poverty alleviation program has been established in order to reduce gap of lower bad living condition of Rwandans due to genocide took place in 1994 against Tutsi. In 1994 the poverty rate was 78%, in year of 2000 poverty rate was 60.4%, 2011 poverty rate was 44.9%. 2014 poverty rate was 39.1% and in 2020 poverty rate was 20%. So, even if the poverty rate mentioned above are decreasing, poverty rate of 20% in 2020 is still high meaning that many people are in the poverty which is the main problem in this studies.

O artigo apresenta uma revisão das pesquisas empíricas realizadas sobre o reconhecimento da tortura no Distrito Federal, de 2015 a 2020. Em um primeiro momento, são trazidos dados levantados a partir de relatórios de organismos internacionais e organizações não governamentais e consultas ao serviço “Disque 100” da Secretaria de Direitos Humanos da Presidência da República, os quais permitem a identificação do perfil das denúncias de tortura no Brasil e, mais especificamente, no Distrito Federal. Na segunda etapa, foi elaborado perfil dos casos de tortura efetivamente julgados pelo Tribunal de Justiça do Distrito Federal e Territórios, de 2011 a 2020, apresentando dados coletados em audiências de custódia e com o Ministério Público do Distrito Federal e Territórios. Por fim, evidenciou-se a distância entre o perfil da tortura notificado a organismos internacionais, organizações não governamentais e ao serviço “Disque 100” e o perfil da tortura efetivamente processado, julgado e condenado no âmbito do sistema de justiça criminal, apontando os vazios institucionais seletivos desde a notícia da tortura, pelos canais à disposição da sociedade, e o reconhecimento desta conduta como crime. As metodologias utilizadas no presente artigo se inserem no campo quantitativo e na pesquisa de fluxo. Na conclusão, são levantadas as possibilidades de reforços para que se enfrente o problema da tortura, no Distrito Federal, como questão de segurança pública e como profundo déficit democrático.

A CONCEPÇÃO DE ESTADO E A INTERVENÇÃO ESTATAL À VIDA PRIVADA: O EXEMPLO DA CIRURGIA PLÁSTICA
Authors: Lima Marco Aurélio Schetino de
Published: November 2021

A intervenção do Estado, no Brasil, é crescente devido à herança social, cultural e jurídica da concepção de Estado ao próprio indivíduo, dada a maneira pela qual se articulou a formação da relação entre as pessoas e o Estado, a ponto de moldar premissas muito particulares que se prendem ao discurso jurídico, para legitimar a ausência de espaços, verdadeiramente, privados. A cirurgia plástica, como ato máximo de disposição individual, assume o papel de ícone da abrangência do espaço público e da inexistência de ambiente para o cultivo da cidadania.
Modern Imaging Techniques and Their Role in Contact Radiation Therapy (Brachytherapy) Planning
Authors: Nudnov N. V. , Titova V. A.
Published: November 2021

The paper considers an algorithm for the diagnostic study of patients with cancer of different localization, the possibility and feasibility of involving imaging techniques in radiation therapy and brachytherapy (BT) planning. The most widely used ultrasound in BT planning does not exclude a subjective assessment of the boundaries of the tumor and organs at risk, as well as the inaccuracies caused by endostatic devices. Magnetic resonance imaging (MRI) provides a high level of achievement of the criteria necessary for BT planning, but it has financial constraints and the need for individual selection of research conditions. Computed tomography (CT) is the most effective technique for visualizing the tumor, endostatic devices, and organs at risk for BT 3D planning. The involvement of MRI and positron emission tomography with CT in BT planning is a promising area that requires equipping with a mathematical tool for double and triple contouring of the tumor and organs at risk and for defining protection priorities. The prescribed and used focal dose should be controlled by direct dosimetry methods to ensure quality assurance.

Published: November 2021

Objective: to evaluate pharmacoeconomic advantages of the application of magnetic resonance imaging (MRI) with hepatobiliary-specific contrast agent – gadoxetic acid in addition to contrast-enhanced computed tomography (CT) in the diagnosis of hepatocellular carcinoma (HCC).

Material and methods. We performed the modeling and obtained the results of the pharmacoeconomic study: effectiveness analysis, cost analysis, and cost-effectiveness analysis. The cost analysis included only direct medical costs (the cost of contrast-enhanced CT, gadolinium-based contrast agent (GBCA) for MRI, and therapy per a patient with verified HCC diagnosis after diagnostic procedures). The financing was performed from the Compulsary Health Insurance Fund. The calculations were made per 1 patient.

Results. The effectiveness analysis showed that the diagnostic scheme CT + MRI with gadoxetic acid was the most effective complex for the diagnosis of HCC because its application provided 50% of patients with 5-year overall survival (4.8 years), which was significantly higher than in patients who were diagnosed HCC with CT + MRI with extracellular GBCA (2.3 years) or CT (3.7 years). The cost-effectiveness analysis showed that the diagnostic scheme with gadoxetic acid was dominant because each disability-adjusted life year required fewer costs (14 862 rubles) in comparison with CT + MRI with extracellular GBCA (25 293 rubles) or CT (46 540 rubles). According to the results of the incremental cost-effectiveness ratio analysis, the application of the diagnostic complex with gadoxetic acid was characterized by the lowest rate of additional costs per 1 disability-adjusted life year.

Conclusion. The pharmacoeconomic study showed that the application of MRI with a hepatospecific contrasting agent – gadoxetic acid in addition to contrast-enhanced CT was an effective and economically beneficial method of early HCC diagnosis.

Objective: to compare the results of staging the severity of viral pneumonia in patients with COVID-19 based on the results of chest computed tomography (CT) using the empirical visual scale CT 0–4 and chest CT severity score (CT-SS) point scale, as well as to assess their prognostic value.

Material and methods. Chest CT scans and anamnestic data in patients hospitalized to a non-specialized center repurposed for the treatment of new coronavirus infection, were analyzed. Chest CT analysis was performed by two radiologists using CT 0–4 and CT-SS scales.

Results. The time course of changes in the severity of lung parenchymal lesions, by using both scales, was found to be similar: the maximum magnitude of lung tissue changes was recorded on day 5 of the disease. In cases of death, there was a significantly more extensive lung parenchymal involvement at admission to the center than in recovered patients, which was also true for both CT data assessment systems. Bothscales demonstrated comparable diagnostic and prognostic value: there were no statistically significant differences in sensitivity, specificity, and predictive value of a fatal outcome. Both the CT 0–4 scales and the CT-SS are based on the estimation of the volume of the affected lung tissue, but when the CT 0–4 scale was employed, additional criteria were used in some cases: the presence of hydrothorax and the determination of the maximum score for the most affected lung. Not all patients with a pronounced CT picture of viral pneumonia had a fatal outcome, which may indicate the presence of other factors that increase its risk.

Conclusion. Both CT 0–4 and CT-SS scales have similar predictive values. The greater severity of parenchymal damage assessed by these CT scales was associated with the higher mortality rate.

Authors: Yadrentseva S. V. , Nudnov N. V. , Gasymov Emil’ G.
Published: November 2021

The paper presents two clinical cases of patients with giant renal angiomyolipomas (AML), in one of whom its course was complicated by intratumoral hemorrhage. It describes key diagnostic criteria for computed tomography (CT), as well as the distinctive features of other neoplasms that should undergo a differential diagnosis. The similar clinical presentations and morphological characteristics of different renal neoplasms can cause certain diagnostic difficulties; however, the carefully collected historical data and distinctive criteria allow AML to be identified. Due to its high sensitivity and specificity, abdominal contrast-enhanced CT is an effective imaging technique in the detection and differential diagnosis of giant renal AML.

Published: November 2021

The food allergy and allergen control are important for global health concerns. Latent allergens are a paramount problem in the specialized food products. Cross-contact and post-cleaning contamination are the main sources of these problems. According to the norms of the Technical Regulation Custom Union N 027/2012 and the Codex Stan 118-79 standard, the gluten content in food products should not exceed 20 mg / kg of the product. The purpose of this study was to analyze raw materials for the gluten-free food products manufacture to justify the HACCP system implementation. The samples of gluten-free flours were selected as research objects to assess the cleanliness of storage, transportation and production facilities in factories producing gluten-free products. In this study, we analyzed the samples of gluten-free flours to assess the cleanliness of storage conditions, transportation and industrial premises in gluten-free factories. The results showed that when using raw materials stored under improper conditions an increase in the gluten content in the final product is observed. We concluded that the gluten-free flours storage conditions in a room with gluten-containing raw materials are unacceptable, because the final product will have high gluten content. Thus, this product cannot be marketed as gluten-free. In addition, we analyzed the washes from the equipment after baking cookies from these flours. We found that in order to comply with regulations, it was necessary to conduct 3 consecutive washing
