Published: November 2021

As the automotive industry shifts from internal combustion engine (ICE) vehicles to electric vehicles (EVs), many countries are setting new strategies in their transportation sector. The Li-ion battery is currently the most common battery used in EVs due to its high energy density, durability, safety, and cost competitiveness. Nickel is predicted to be an essential component for the lithium nickel cobalt manganese oxide (NMC) as a cathode material of choice for EV applications. Indonesia, one of the world’s largest nickel ore suppliers, put an export ban on nickel ore effective from 2020. The bold movement was intended to initiate the domestic EV industry and encourage investors abroad to drive their manufacturing activities into the country. On the other hand, the global Li-ion battery manufacturers who imported nickel from Indonesia had to restrategize their businesses. This review discussed the chronological events leading to the ban and after the ban from the media, government regulations, and literature reviews. The authors of this study also conducted interviews and attended seminars with the national experts and key players in the battery and EV industry to gain their most pertinent insights. The SWOT analysis of the reviewed materials indicated that while the Indonesian battery industry is still new, it needs to diversify its research and development activities and collaborate internationally to optimize the utilization of its resources and meet the purchasing power of the domestic EV market. Finally, this study summarized six key factors to support Indonesia’s ambition to be a new regional hub for EVs. These factors are: (1) pricing, (2) technology, (3) policy, (4) investment, (5) infrastructure, and (6) compliance with sustainability standards.

Published: November 2021

Metschnikowia pulcherrima is a non-conventional yeast with potential to be used in biotechnological processes, especially those involving low-cost feedstock exploitation and biocontrol applications. The combination of traits that supports these industrial applications in M. pulcherrima also makes it an attractive option to study in the context of livestock health. In this study, we examined the specific interactions between M. pulcherrima and multiple avian pathogenic bacteria. We tested individual bacteria–yeast interactions and bacterial combinations in both solid and liquid media and in variable nutrient environments. Across multiple isolates of M. pulcherrima, we observed different levels of antimicrobial activity, varying from supporting the growth of competing bacteria through suppression and bacterial killing, and we found that these responses varied depending on the bacterial strains and media. We identified multiple molecular routes, including proteins produced by M. pulcherrima strains, that acted to control these microbial interactions. Furthermore, protein screening revealed that M. pulcherrima strains were induced to produce proteins specifically when exposed to bacterial strains, suggesting that fine-tuned mechanisms allow M. pulcherrima to function as a potential lynchpin in a microbial community.
Recovery of Altered Diabetic Myofibroblast Heterogeneity and Gene Expression Are Associated with CD301b+ Macrophages
Authors: Haas MaryEllen R. , Nguyen Darlene V. , Shook Brett A.
Published: November 2021

Diabetic wound healing is associated with impaired function and reduced numbers of myofibroblasts, a heterogeneous cell population with varying capacities to promote repair. To determine how diabetes alters myofibroblast composition, we performed flow cytometry and spatial tissue analysis of myofibroblast subsets throughout the healing process in diabetic (db/db) and control (db/+) mouse skin. We observed reduced numbers of profibrotic SCA1+; CD34+; CD26+ myofibroblasts in diabetic wounds five days after injury, with decreased expression of fibrosis-associated genes compared to myofibroblasts from db/+ mouse wounds. While the abundance of myofibroblasts remained reduced in db/db mouse wounds compared to controls, the altered myofibroblast heterogeneity and gene expression in diabetic mice was improved seven days after injury. The natural correction of myofibroblast composition and gene expression in db/db wound beds temporally corresponds with a macrophage phenotypic switch. Correlation analysis from individual wound beds revealed that wound healing in control mice is associated with CD206+ macrophages, while the rescued myofibroblast phenotypes in diabetic wounds are correlated with increased CD301b+ macrophage numbers. These data demonstrate how diabetes impacts specific subsets of myofibroblasts and indicate that signaling capable of rescuing impaired diabetic wound healing could be different from signals that regulate wound healing under nonpathological conditions.

Autologous antigen-specific therapies based on tolerogenic dendritic cells (tolDC) offer the possibility to treat autoimmune diseases by restoring homeostasis and targeting specifically autoreactive responses. Here, we explore the hypothesis that systemic inflammation occurring in autoimmune diseases, such as multiple sclerosis (MS), can generate a disease-specific environment able to alter the functionality of tolDC. In this context in fact, a combined therapy of tolDC with an immunomodulatory treatment could potentiate the beneficial effect of this antigen-specific cell therapy. For this purpose, we analyzed the efficacy of a combined therapy based on the use of vitamin D3 (VitD3)-tolDC plus interferon beta (IFN-beta) in MS. VitD3-tolDC were generated from healthy donors and MS patients and co-cultured with allogeneic peripheral blood mononuclear cells, in the presence or absence of IFN-beta. In vitro, VitD3-tolDC treatment reduced the percentage of activated T cells and allogeneic proliferation, whereas VitD3-tolDC+IFN-beta treatment enhanced the suppressive ability of VitD3-tolDC and, additionally, induced a shift towards a Th2 profile. To determine the clinical benefit of the combined therapy, C57BL/6-experimental autoimmune encephalomyelitis (EAE)-induced mice were treated with antigen-specific VitD3-tolDC and/or IFN-beta. Treatment of EAE mice with combined therapy ameliorated the disease course compared to each monotherapy. These results suggest that a combined therapy based on antigen-specific VitD3-tolDC and IFN-beta may represent a promising strategy for MS patients.

Published: November 2021

Matrix metalloproteinase (MMP) dysregulation is implicated in several diseases, given their involvement in extracellular matrix degradation and cell motility. In lymphangioleiomyomatosis (LAM), a pulmonary rare disease, MMP-2 and MMP-9 have been detected at high levels in serum and urine. LAM cells, characterized by a mutation in the tuberous sclerosis complex (TSC)1 or TSC2, promote cystic lung destruction. The role of MMPs in invasive and destructive LAM cell capability has not yet been fully understood. We evaluated MMP-2 and MMP-7 expression, secretion, and activity in primary LAM/TSC cells that bear a TSC2 germline mutation and an epigenetic modification and depend on epidermal growth factor (EGF) for survival. 5-azacytidine restored tuberin expression with a reduction of MMP-2 and MMP-7 levels and inhibits motility, similarly to rapamycin and anti-EGFR antibody. Both drugs reduced MMP-2 and MMP-7 secretion and activity during wound healing and decreased their expression in lung nodules of a LAM mouse model. In LAM/TSC cells, MMP-2 and MMP-7 are dependent on tuberin expression, cellular adhesion, and migration. MMPs appears sensitive to rapamycin and anti-EGFR antibody only during cellular migration. Our data indicate a complex and differential modulation of MMP-2 and MMP-7 in LAM/TSC cells, likely critical for lung parenchyma remodeling during LAM progression.
RETRACTED: Animal Models in Bladder Cancer

Published: November 2021

Background: Bladder cancer (urothelial cancer of the bladder) is the most common malignancy affecting the urinary system with an increasing incidence and mortality. Mouse models of bladder cancer should possess a high value of reproducibility, predictability, and translatability to allow mechanistic, chemo-preventive, and therapeutic studies that can be furthered into human clinical trials. Objectives: To provide an overview and resources on the origin, molecular and pathological characteristics of commonly used animal models in bladder cancer. Methods: A PubMed and Web of Science search was performed for relevant articles published between 1980 and 2021 using words such as: “bladder” and/or “urothelial carcinoma” and animal models. Animal models of bladder cancer can be categorized as autochthonous (spontaneous) and non-autochthonous (transplantable). The first are either chemically induced models or genetically engineered models. The transplantable models can be further subclassified as syngeneic (murine bladder cancer cells implanted into immunocompetent or transgenic mice) and xenografts (human bladder cancer cells implanted into immune-deficient mice). These models can be further divided—based on the site of the tumor—as orthotopic (tumor growth occurs within the bladder) and heterotopic (tumor growth occurs outside of the bladder).

A práxis freiriana  tem sido vivenciada no Projeto de Extensão “Cultura da Palavra e Saúde Mental” da Universidade Federal de São Paulo, desde 2016, em processos de ensino/ aprendizagem e de cuidado em saúde mental em 4 Centros de Atenção Psicossocial (CAPS) na cidade da Santos/SP. A partir dos conceitos freirianos de leitura de mundo, dialogicidade, círculo de cultura e conscientização, este artigo apresenta a sistematização das experiências vividas ao longo do ano de 2020. O processo de sistematização realizado, inspirado no clássico livro “Para sistematizar experiências” (JARA, 1996), possibilitou aos sujeitos envolvidos uma melhor compreensão do trabalho realizado, a problematização da prática dos(as) educadores(as), análise da relação entre educadores(as), educandos(as) e serviços, e a construção de conhecimentos a partir da educação popular.
Por uma formação inicial de professores(as) de Moçambique na perspectiva freiriana: possibilidades e limites

Published: November 2021

Este artigo apresenta resultados de uma investigação que teve como objetivo examinar o atual estado da formação inicial de professores de Moçambique, com vistas a sugerir reformulações baseadas na proposta freiriana de educação. Com relação aos procedimentos metodológicos, optou-se pela abordagem qualitativa, com ênfase na investigação temática de Paulo Freire. A coleta de dados foi realizada por meio do Círculo de Cultura freiriano. Foram sujeitos desta pesquisa sete alunos e cinco alunas do Instituto de Formação de Professores de Inhamizua, no Município da Beira de Moçambique. A análise dos dados foi realizada pela técnica de Análise de Conteúdo temático-categorial. Os resultados permitiram concluir que a formação inicial de professores de Moçambique ainda se encontra norteada pelos princípios de uma educação bancária, o que obstaculiza a autonomia intelectual do(a) educando(a). Assim, inferiu-se que as práticas docentes moçambicanas não favorecem uma reflexão crítica sobre a prática de educadores(as) e educandos(as). Concluiu-se, portanto, que será preciso investir em formações continuadas que possibilitem uma práxis educativa crítico-reflexiva, por meio de uma pedagogia dialógica.
Por uma Pedagogia dos direitos humanos em Paulo Freire
Authors: Santos Ivone Laurentino dos
Published: November 2021

Paulo Freire, na sua compreensão ético-político-antropológica de uma epistemologia crítico-educativa, que tem como ponto central a humanização das sofridas gentes, dedicou-se à luta pelos plenos direitos e igualdade de oportunidades para todos e todas. Com base na premissa de que a práxis de Freire é indissociável da luta pela dignidade humana, torna-se necessário o resgate de sua pedagogia libertária, potencializando as vidas dos que se encontram à margem da sociedade, de modo a evidenciar a substantividade dos Direitos Humanos. Este texto tem como objetivo ampliar e qualificar o debate sobre a importância de uma Pedagogia dos Direitos Humanos em Paulo Freire, a partir da análise teórica e conceitual da sua 'ética universal do ser humano', na interface com os Direitos Humanos. A defesa do acesso à Justiça pelos vulneráveis sociais atravessa todo o pensamento de Freire, na sua luta incessante e engajada pela garantia dos Direitos Humanos. Freire expressou solidariedade pessoal aos excluídos da ética de mercado, afirmando o Direito como prática para a libertação. A teoria de Freire é, em síntese, um Tratado dos Direitos Humanos, visto que atravessada pela problematicidade, politicidade, eticidade e amorosidade. A proposta de uma Pedagogia dos Direitos Humanos em Freire, encontra legitimidade no fato de que, o discurso freiriano, nascido do real e concreto, em favor dos condenados da terra, dos oprimidos, dos esfarrapados do mundo, pode ser uma grande ferramenta na luta para se garantir condições de vida digna àqueles e àquelas que, em pleno Sec. 21, ainda sofrem com a negação de suas liberdades.

Freire e seu olhar dialógico: uma proposta de leitura de literatura em língua estrangeira para a construção da alteridade
Authors: Cerqueira Aliana Georgia Carvalho
Published: November 2021

Neste trabalho, discorre-se sobre uma proposta de leitura em defesa de que as ideias freireanas continuam necessárias e seu olhar tem contribuições relevantes até mesmo para a leitura de literatura em língua estrangeira. A educação problematizadora de Paulo Freire aponta para uma abordagem de leitura dialógica que visa um leitor autônomo como parte do processo de leitura e o professor como mediador desta na construção dos sentidos possibilitados pelo texto, inclusive, literário. Utiliza-se a pesquisa bibliográfica e, mostrando convergências entre conceitos de Bakhtin e o pensamento de Freire, propõe-se que ler é encontrar-se com o Outro, é (re)construir linguagens, é saber-se parte de um todo, de uma cultura que parecia alheia, porém, que define o Eu como sujeito no mundo. Isto é, na aproximação entre uma filosofia da linguagem bakhtiniana e uma teoria pedagógica freireana, entende-se o lugar da literatura nas relações sociais. Consequentemente, o processo de ensino-aprendizagem de leitura de literatura em um novo idioma deve realizar-se pela perspectiva da dimensão social da linguagem. Mediar a leitura de narrativas literárias em língua estrangeira é construir pontes entre a cultura do aluno e a cultura ensinada de forma sistemática, utilizando estratégias de leitura, desenvolvendo a curiosidade de que trata Freire, promovendo o diálogo entre o modo de ver o mundo e a janela de possibilidades que se abre para a compreensão da/pela narrativa literária. Finalmente, a dialogia dessa abordagem mostra-se presente, também, na construção da alteridade, isto é, uma identidade marcada pelo outro.

Published: November 2021

Electrolysis is one of the methods used to remove heavy metal mercury (Hg). The electrolysis process is carried out on residual liquid waste from gold processing by utilizing chemical reactions through electrodes immersed in an electrolyte solution. This research method is experimental. We conducted laboratory tests to see the electrolysis process on the residual liquid waste from gold processing in a 10-liter container. We took samples from 10 different containers, 1 liter each from each tub. Sampling time was carried out in the morning, afternoon, and evening. The results showed a significant decrease in mercury (Hg) levels up to 1.30% with 12 volts of electricity for 100 minutes. In contrast, the lowest decrease occurred in the electric current of 3.3 volts within 25 minutes. We use the electrolysis method. This heavy metal removal technique can be applied and managed properly by the community and local government to minimize heavy metal pollution such as mercury in the surrounding environment due to waste from the community's traditional gold processing.

Imaginarios sociales de los trabajadores ferroviarios de Junín (1948-1973)
Authors:   , Sagastume Ana Leticia
Published: November 2021

Esta tesis aborda el estudio de los imaginarios sociales que se constituyeron en torno a la actividad ferroviaria en la ciudad de Junín, provincia de Buenos Aires, desde el enfoque de la historia oral. Se lo hace a partir de los testimonios sobre las experiencias y las representaciones de los trabajadores ferroviarios de la ciudad, que ingresaron a la empresa durante las décadas de 1940 y 1950. Se considera que resulta un aporte a la historiografía ferroviaria desde la perspectiva de los imaginarios sociales, a partir del estudio de un período de veinticinco años signado por algunos acontecimientos fundamentales, tales como la nacionalización de la empresa en 1948 y la crisis ferroviaria que se evidenció en la década de 1960, los cuales suscitaron profundas transformaciones en la interpretación de las experiencias y en los valores del colectivo. Además, hacia el final de la década, se analiza la elaboración y puesta en práctica de algunos proyectos implementados a escala local que intentaron brindar una respuesta superadora a la crisis ferroviaria del país. Estas iniciativas, a pesar de que no perduraron en el tiempo dieron lugar a poderosas representaciones sobre la capacidad técnica de los trabajadores ferroviarios de Junín.

Authors: Belenkevich N. I. , Ilyinkov V. A.
Published: November 2021

A single mathematical model of time characteristics of signals, links and responses of telecommunications and radioelectronics systems is suggested. It embodies Dirac- and Heaviside responses of all types of linear links, as well as their responses to the input in the form of periodic signals, no periodic finite and no periodic eternal signals. On the basis of the suggested model the algorithm for calculation of time characteristics was developed, which allows creation of effective automated simulations procedure of signals, links and responses in time-domain. The comparative quantitative analysis of accuracy of the suggested algorithm and discrete Fourier transformation (DFT) algorithm was carried out.
Structures of processors for calculating the instant Walsh spectrum
Authors: Budzko A. A. , Dvornikova T. N.
Published: November 2021

The work is devoted to the development of circuits for fast Walsh transform processors of the serialparallel type. The fast Walsh transform processors are designed for decoding error-correcting codes and synchronization; their use can reduce the cost of calculating the instantaneous Walsh spectrum by almost 2 times. The class of processors for computing the instantaneous spectrum according to Walsh is called serialparallel processors. Circuits of the fast Walsh transform processors of serial-parallel type have been developed. A comparative analysis of the constructed graphs of the fast Walsh transform processors is carried out. A method and a processor for calculating the Walsh transform coefficients are proposed, which allows increasing the speed of the transformations performed. When calculating the conversion coefficients using processors of parallel, serial and serial-parallel types, it was found that controllers of the serial-parallel type require 2(N–1) operations when calculating the instantaneous spectrum according to Walsh. The results obtained can be used in the design of discrete information processing devices, in telecommunication systems when coding signals for their noise-immune transmission and decoding, which ensures the optimal number of operations, and therefore the optimal hardware costs.
Interperiod coherent integration of the received signal with a variable repetition period of the probing signal
Authors: Heister S. R. , Semashko P. G.
Published: November 2021

Interperiod coherent integration of the received signal provides an increase in the signal-to-noise ratio and is simply implemented with a fixed repetition period of the probing signals. In practice, pulsed radars use a variable repetition period to protect against blind speeds. The algorithms of the interperiod coherent integration with a variable repetition period have been developed and their features have been revealed, which are advisable to take into account in the practical implementation in the radars. These features determine the complexity of the interperiod coherent integration algorithm, the radial velocity (Doppler frequency) survey interval and the spectrum features. An algorithm is developed with simultaneous interperiod coherent integration of the received signal and a single-delay clutter cancelation in the spectral domain in the case of variable repetition period of the probing signals. The quantitative indicators obtained by modeling are presented and a comparative analysis is carried out.

One of directions of improving parameters of analog integrated circuits is a development of new and modernization of existing designs of integrated elements without significantly changing of a technological route of integrated circuit manufacturing with a simultaneous creation of new integrated elements models. The article considers the results of experimental studies of the double gate junction field-effect transistor manufactured according to the 3CBiT technological route of JSC Integral. Based on the obtained results, the electrical model of double gate junction field-effect transistor is proposed, which describes the features of its application in analog integrated circuits. Comparison of I-V characteristics of measurements results and created model simulation are presented. A small capacity and a reverse current of a double gate junction field-effect transistor top gate, an ability to compensate for the DC (direct current) component of an input current provide a significant improvement in the characteristics of analog integrated circuits such as electrometric operational amplifiers and charge-sensitive amplifiers. The developed double gate junction field-effect transistor can be used in signal readout devices required in the analog interfaces of space instrument sensors and nuclear electronics.

Introdução: A obesidade infantil é uma doença que apresenta uma série de prejuízos para a saúde das crianças, as quais são mais propensas a desenvolver futuramente doenças cardiovasculares, como hipertensão, acidente vascular cerebral, diabetes e dislipidemia. Observa-se que há um aumento da sua prevalência no Brasil e em outros países do mundo. Os dados mostram uma alta presença dessa doença, chegando a uma taxa de 10% entre crianças de 5 a 9 anos de idade. Alguns fatores aumentam as chances do aparecimento de obesidade na infância, como a obesidade materna durante a gestação, o baixo nível socioeconômico e a baixa escolaridade materna. Dessa forma, por ser uma doença com sérias consequências, deve-se haver uma maior atenção voltada para identificação e intervenção precoces a fim de reduzir a sua prevalência e as suas complicações clínicas. Objetivo: Verificar a prevalência de obesidade infantil na atenção primária em uma cidade do alto sertão no Brasil. Metodologia: Tratou-se de um estudo de campo de caráter exploratório, descritivo, com abordagem quantitativa. A pesquisa foi realizada em 5 UBS’s da cidade de Cajazeiras-PB, a qual conta com 17 UBS’s urbanas. A população foi de crianças na faixa etária de 2 a 11 anos que estavam sendo acompanhadas pela puericultura e realizando suas medidas antropométricas no dia do peso. A coleta de dados foi realizada com um questionário semiestruturado com parâmetros, como peso, idade, sexo e altura, para a caracterização das crianças e foi feita entre os meses de novembro de 2017 e fevereiro de 2018. A amostra foi composta por 98 crianças com idade entre 2 e 11 anos. Resultados e Discussão: A prevalência de crianças com sobrepeso foi de 12,2% e de crianças com obesidade foi de 25,5%, confirmando, dessa forma, uma alta taxa de participantes com excesso de peso. Tais dados são bastante preocupantes, pois a obesidade é uma doença que apresenta sérias consequências para a saúde, diminuindo a qualidade de vida dos seus portadores. Entre as crianças com sobrepeso e obesidade, 32,4% das mães ainda não tinham concluído o ensino fundamental. Muitos estudos analisados conseguiram apontar relação entre o grau de escolaridade da mãe e presença de obesidade em seus filhos. Conclusão: Por meio da análise, percebe-se que houve a caracterização das crianças quanto ao grau de obesidade e sobrepeso e sua prevalência. Alguns fatores sociodemográficos foram relacionados à ocorrência de obesidade na infância, como a baixa escolaridade materna. Assim, espera-se que essa pesquisa contribua para alertar as pessoas que essa doença vem progredindo de forma preocupante na sociedade e se não evitada de forma adequada, pode causar sérias consequências para a saúde da população infantil.

The Government of Indonesia, through the Ministry of Education and Culture, mandates each university to organize quality education. To produce graduates who meet national standards of higher education (SN-Dikti). Hence, each university must evaluate its performance to know its current condition. Unfortunately, most universities in Indonesia have difficulty in measuring their performance. Therefore, the university becomes difficult to establish a strategic plan forward. This study aims to produce a performance dashboard that can help university leaders evaluate their performance. This Performance Dashboard visualizes Key Performance Indicator (KPI) information from a strategic plan in one screen. This research uses a user-centric approach with four main stages, namely, identification of needs, planning, prototype design, and prototype review to produce the performance dashboard. The Performance Dashboard produces interactive gauge charts (baseline, targets, and performance achievements) so that it can visualize university KPI information. The results of user reviews showed that the KPI visualization by the performance dashboard was declared correct and could be useful as a guide in preparing a self-evaluation.

Website Design, Information Systems, Information, SMA Negeri 1 Sambuara Essang, Talaud SMA Negeri 1 Sambuara, South Essang District, Talaud Islands Regency is one of the educational institutions that must also manage the data to facilitate information for both the school and the community. Based on the observations, the information management system for SMA Negeri 1 Sambuara still use input system manually, e.g. school profiles, student data, teacher data, and lesson schedule information. The public can only find the information out regarding schools and Teaching & Learning Activities (KBM) by visiting the school directly. This research aims to find out the problem before building an Information System at SMA Negeri 1 Sambuara Based on a Website, it is hoped that this system can facilitate socialization or promote the school to the wider community by using the website. From the results of this discussion, it can be concluded that; this system will make it easier for the school to provide information about student data to visitors or the public, and this system can also make it easier for visitors or the public to find information about student data without knowing distance and time. Comparison of the old system and the new system i.e. The old system is still done manually, while the new system has been carried out in a computerized system, the old system is not efficient and effective, while the new system is the opposite. In the new system, students can input their data directly into the system.

Epidemiological studies link increased fall risk to obesity in older adults, but the mechanism through which obesity increases falls and fall risks is unknown. This study investigates if obesity (Body Mass Index: BM I> 30 kg/m2 ) influenced gait and standing postural characteristics of community dwelling older adults leading to increased risk of falls. One hundred healthy older adults ( age 74.0 ± 7.6 years, range of 56-90 years ) living independently in a community participated in this study. Participants’ history of falls over the previous two years was recorded, with emphasis on frequency and characteristics of falls. Participants with at least two falls in the prior year were classified as fallers. Each individual was assessed forpostural stability during quiet stance and gait stability during 10 meters walking. Fall risk parameters of postural sway ( COP area, velocity, path-length ) were measured utilizing a standard forceplate coupled with an accelerometer affixed at the sternum. Additionally, parameters of gait stability ( walking velocity, double support time, and double support time variability ) were assessed utilizing an accelerometer affixed at theparticipant’s sternum. Gait and postural stability analyses indicate that obese older adults who fell have significantly altered gait pattern ( longer double support time and greater variability ) exhibiting a loss of automaticity in walking and, postural instability as compared to their counterparts ( i.e., higher sway area and path length, and higher sway velocity ) further increasing the risk of a fall given a perturbation. Body weight/BMI is a risk factor for falls in older adults as measured by gait and postural stability parameters.

The aim of this paper is to propose a comprehensive approach for the predictive maintenance of complex equipment. The approach relies on a physics of failure ( PoF ) model based on expert knowledge and data. The model can be represented as a multi-state Petri Net where different failure mechanisms have been discretized using physical degradation states. Each physical state can be detected by a unique combination of symptoms that are measurable using diagnostic tools. Based on actual diagnostic information, a diagnostic algorithm is used to identify active failure mechanisms and estimate their propagation using the Petri Net technique. Specific maintenance actions and their potential effects on the system can be associated with target states. A prognostic algorithm using a colored Petri Net propagates active failure mechanisms through the target physical states. A predictive maintenance approach is therefore proposed by allowing specific maintenance actions to be determined in a reasonable timeframe. A case study is presented for an actual hydro-generator. Finally, model limits are discussed and potential areas for further research are identified.

The Environmental Control Systems ( ECS ), used to provide air to the aircraft cabin at the correct pressure and temperature, is a key driver of maintenance interruptions for military and civil aircraft. Fault detection is particularly difficult, due to the lack of instrumentation and the ability of the ECS’s control system to mask symptoms. Understanding how component degradation affects measurable thermodynamic parameters is key to developing a condition monitoring system for an ECS. This work focuses on the development of a thermodynamic model of a Boeing 737-200 ECS capable of simulating faults in three types of component: heat exchangers, valves, and water separators. The thermodynamic model has been validated using data collected on a ground-based instrumented B737-200 ECS. The results show how a thermodynamic model can be used to simulate the change of temperatures and pressures across the ECS when components degrade.

Készülő doktori disszertációmban a Fehér megyei Tövis magyar közösségének identitás-konstrukcióját vizsgálom, melynek része a közösségi és egyéni önkép. E tanulmányom az önképformálás lokális és (erdélyi) regionális szórványsajátosságainak, az auto- és heterosztereotípiák leírásának, a románság magyarokról alkotott vélt és tényleges véleményének vizsgálatával az identitás alakulását érő főbb, a téma szempontjából releváns hatásokra mutat rá. A magyarság önképét két dimenzióban értelmezem: a többi magyar közösségéhez képest és a románságéhoz viszonyítva – román nemzetiségű adatközlőimtől a magyarokról alkotott képüket illetően érdeklődtem.
