Published: March 2024

The aviation industry faces an ever increasing pressure to reduce its cost in order to gain competitive advantages. Since aircraft maintenance contributes strongly with about 17% to the overall direct operating cost (DOC), maintenance providers are required to continuously reduce their cost share as well. As a result, a lot of effort is put into the exploitation of the potential of emerging digitalization technologies to predict upcoming system faults and, therefore, reduce the projected maintenance impact. The detection of early stage faults and prediction of remaining useful lifetimes (RUL) for various systems, including aircraft engines as high-value assets, has been a focal point for many research activities already. A key aspect – necessary for an accurate prediction of future behavior – is the correct mapping of ambient conditions that have led to the respective system condition. Therefore, it is necessary to combine data information throughout an aircraft’s life from different stakeholders to gain valuable insights. However, as the aviation industry is strongly segregated with many parties involved, trying to gain their own competitive advantage, the required information about the operating condition is often not available to independent maintenance providers. Thus, modeling engine degradation often needs to rely on estimated nominal conditions, limiting the ability to precisely predict engine faults. With this paper, we will develop a model that allows users to estimate the experienced engine load during take-off by only using publicly available information, i.e. airport weather information reports and public flight data. The calculated engine load factors are computed in terms of an engine pressure ratio (EPR) derate. The results are benchmarked with the actual engine derate, obtained for different operators and various ambient conditions, to enable an identification of challenges for the load prediction and areas of improvement. The developed model will help to adjust engine failure projections according to the experienced ambient conditions and, therefore, supports the development of better engine degradation models.

Published: March 2024

Power electronic modules undergo electro-thermal stresses due to power losses that lead to several kinds of degradations, and finally to failure. In order to prevent power electronic module failure, one should assess its state of health in real-time operation. For this purpose, Prognostics and Health Management (PHM) approach could be a promising tool for reliability evaluation for an IGBT device. The Insulated Gate Bipolar Transistor is a three-terminal power semiconductor device used as an electronic switch which combines high efficiency and fast switching. In this paper, an analytical model is proposed that describes the metallization to wire-bond contact resistance. This model computes the crack length and then using online measurement the rate of crack propagation is computed and used to predict the future crack lengths with the assumption of linearity in crack propagation. The main failure mechanism of the IGBT device in this paper is the crack propagation in the wire-bond interconnection. The usual aging indicator of such damages is the voltage between the collector and the emitter of current (VCE) that increases with degradation. The analytical model is related to this indicator and it is based on the contact resistance theory and constriction current lines. The proposed model is hence used to build a prognostics model for estimating the remaining useful lifetime (RUL) of IGBT power modules. The prognostics model is illustrated using aging data coming from accelerated power cycling tests with different stress conditions. The first cycling test is under the conditions of stress duration ton = 3sec and junction temperature swing amplitudes ΔTj = 110 ºC and the second cycling test is under ton = 3sec and ΔTj = 90ºC. Results show a prognostics capability.

Published: March 2024

The automotive industry is being transformed by the application of artificial intelligence and big data analysis. In particular, predictive analytics is becoming a powerful tool for anticipating component failure. This key area of research provides automotive industry manufacturers with lower warranty expenses and incremental service parts revenue while rewarding customers with higher uptime. These benefits are particularly important for commercial vehicles operations such as bus and truck fleets, since analytics led predictive maintenance can prevent inconvenient and costly interruptions of vehicle mission. Accurate prediction models for component failures are especially challenging. This paper describes one such effort for failure prediction of transit bus NOx (Nitrogen Oxides) sensors.

Stringent emissions regulations have made diesel exhaust aftertreatment systems mandatory in nearly all global markets, and NOx sensors play a critical role in control and diagnostic algorithms used by these systems. NOx is measured before and after the SCR (Selective Catalytic Reduction) system with two different components namely Engine out (EO) NOx and System out (SO) NOx. Due to differences in operating conditions and failure rates these two components were studied separately. The results of different Machine Learning algorithms were obtained and compared to get the optimal predictions. Moreover, early life and late life failures were also studied separately to differentiate between random and wear-out failure modes. Highlights of the paper are: - the data collection process, feature engineering and feature selection process, as well as explainable AI (Artificial Intelligence) built on top of the machine learning model. Efforts were also taken to keep the approach generic and not become too component specific so that it can easily be replicated for predicting other failures on other product lines or of different components.
Post-prognostics decision making for a two-stacks fuel cell system based on a load-dependent deterioration model

Published: March 2024

Multi-stacks proton exchange membrane fuel cell (PEMFC) system has been applied to combined heat and power system (CHP), and serves as an alternative energy device due to its high efficiency and zero emission. Owing to the limited durability and larger power supply demand, the management of multi-stacks PEMFC system to obtain a longer service time has received recently growing attention. From the prognostics and health management (PHM) point of view, a post-prognostics decision making for multi-stacks PEMFC system is addressed in this work. Firstly, a load-dependent stochastic deterioration model is proposed for PEMFC. The overall ohmic resistance is chosen as the health indicator of PEMFC. Then the resistance is modeled using a Gamma process whose shape parameter is taken as a function of the current load applied to the stack. Finally, for the post-prognostics decision making phase, a decision probability based load repartition criterion is built to identify the optimal load split between the two stacks. The decision probability is calculated based on the system lifetime results (EoL) in each decision step. The EoL results of the decision phase are further compared with the system EoL that calculated without decision making strategy. The comparison result shows that extended service time can be achieved using the proposed post-prognostics decision making method.
Ninotsminda Oil and Gas Field Development Through the Methods of Hydrodynamic Impact on the Formation
Authors:   Georgian Technical University, Durglishvili Giorgi , Sharikadze Mevlud ,   Georgian Technical University
Published: March 2024

Ninotsminda oil-and-gas bearing deposit connected with the fractured-cavernous reservoirs of the Middle Eocene volcanogenic-sedimentary suite is in its final, 4th stage of development (operates since 1979). Its energy potential is determined by water drive and gas drive regimes. The main of the prevailing issues is the rapid pace and the scale of production becoming water-cut. Productive suite, that is mainly built with tuff, is anisotropic due to numerous parameters. Respectively, intervals and sections with high and low-filtration properties are identified in the geological cross-section. In addition, the producer well coverage is not dense enough and undeveloped oil-bearing zones (lenses) remain in the spaces between the wells. All of the above indicates that the field is unevenly developed, and certain oil reserves are remaining there. In the period of 2000-2006 and since 2015 the methods of horizontal well drilling and injection of technical water into the productive layer were applied to increase the oil recovery factor. In the result, production (oil and gas) noticeably increased. Application of the complex hydrodynamic methods in the future will enable us to significantly increase the remaining oil production from the stratigraphically lower, water-cut horizons of the productive suite.

Wells for the extraction of precious metals at the poly deposit of Bolnisi municipality are drilled with EPIROC Christensen 140 Crawler Tier III and Atlas Copco Christensen CS 140 drilling rigs. In order to reduce the time required for lowering and removing the drill pipes and to remove the core qualitatively, without loss, and quickly, the Canadian detachable coring gun is used. Drilling wells is produced with CR-650 polymer powder (polyacrylamide) based drilling polymer solution, which, along with the removal of the drilled rock particles, lubricates and cools the drilling tools, and also prevents muds from hardening and, therefore, narrowing of the wellbore and jamming of the drill pipes. When drilling a well in fractured rock, a buffer solution is used to prevent absorption of the drilling fluid. The use of the above-mentioned modern methods has significantly improved the working time balance and technical-economic indicators of drilling.

Published: March 2024

The appropriateness of teaching design thinking to architecture students in Georgia is discussed. Design thinking is a user-centered method that was developed about 60 years ago and is widely used in almost all areas of design, including architecture. Leading architectural firms embrace design thinking. This method also has many opponents, who complain about the lack of creativity, its collective work, and more. In contrast, advocates of design thinking argue that design thinking approaches do not necessarily limit creativity, and that contemporary architecture has become so complex that specialists of only one field cannot account for everything. It is interesting that the main opposition to this methodology was met in the country where it was born – the USA. As for Georgia, the survey of students conducted by the authors of the article at the International Design School of the Georgian Technical University found that the majority of them have a positive attitude and intend to use design thinking in their future activities.

Authors: S Manjula , M Krishna Kumar
Published: March 2024

Objective: The present survey-based study aims to gather clinicians’ perspectives regarding the antibiotic prescription pattern for the management of infections and enteric fever in Indian settings. Methodology: The current multiple-response questionnaire-based survey consisted of 17 questions pertaining to clinical observations, clinical experience, and antibiotic prescription practice of specialists involved in the management of infections and enteric fever. Result: Out of 246 participants, 89% recommended cefixime as the preferred monotherapy drug for enteric fever. The recommended combination therapies for enteric fever were cefixime and ofloxacin, cefixime and azithromycin, and cefpodoxime and ofloxacin, as indicated by 38%, 32%, and 25% of clinicians, respectively. Approximately 61% of the clinicians reported frequently prescribing cefixime for urinary tract infections (UTI). According to 68% of the clinicians, the recommended cefixime dose for treating typhoid fever is 15-20 mg/kg. More than half (55%) of the clinicians recommended amoxicillin/clavulanic acid for the treatment of respiratory infections. Majority (78%) of the clinicians chose cefixime as an effective option for managing recurring infections. A considerable proportion (76%) of clinicians reported no side effects following antibiotic therapy. Conclusion: The study provides valuable insights into the use of antibiotics in infection and enteric fever in Indian settings. Cefixime therapy is recommended by clinicians in the treatment of enteric fever, UTI, and recurring infections. The preferred treatment option for enteric fever includes a combination of cefixime with either ofloxacin or azithromycin. The recommended cefixime dose for typhoid fever is in the range of 15-20 mg/kg. Respiratory infections are typically treated with amoxicillin/clavulanic acid.

Published: March 2024

Acute cerebrovascular accident throughout the world remains the main cause of subsequent disability in persons who have suffered a stroke.
One promising area is neuromuscular stimulation. Functional electrical stimulation is a subtype of neuromuscular stimulation in which stimulation promotes functional and goal-oriented movements in the individual.
A course of functional electrical stimulation was administered while walking to a 74-year-old patient in the late recovery period of an ischemic stroke (the right middle cerebral artery). 14 procedures were performed lasting from 20 to 30 minutes. Before and after the functional electrical stimulation course, a clinical study and a study of the biomechanics of walking were conducted.
The results obtained showed an improvement in clinical indicators, inconsistent changes in the time parameters of the step cycle, an increase in amplitudes in the hip and knee joints, as well as normalization of the function of the knee and ankle joints of the paretic side. Functional EMG research showed both an improvement in muscle activity and normalization of their activity profile, as well as processes of function restructuring that require further study.
During functional electrical stimulation, there were no negative reactions from the patient or irritation of the skin at the locations of the electrodes.
The method of functional electrical stimulation requires further study and reasonable application in this category of patients.

Extracorporeal blood purification is intended to eliminate dysregulation of the immune system. The concept of extracorporeal therapy is based on the nonspecific clearance of inflammatory mediators and triggers, which attenuates the systemic expression of inflammatory mediators. The main types of extracorporeal therapy are hemoadsorption and plasma exchange. Hemoadsorption is used primarily as an adjuvant treatment for septic shock and other severe inflammatory conditions, including severe forms of COVID-19 with cytokine storm.
Reliable data demonstrating the benefit of hemoadsorption in critically ill patientsis is limited. Recommendations for the use of hemoadsorption devices are often based on incomplete data or questionable interpretations of available data. Given the lack of evidence for the benefit of hemoadsorption in the treatment of severe inflammation, sepsis, liver failure and rhabdomyolysis, its routine use in clinical practice is not justified until the mechanisms underlying these findings are fully elucidated.
Plasma replacement is a potentially life-saving invasive extracorporeal blood purification procedure that replaces plasma with a substitute fluid (saline, albumin solution, fresh frozen plasma, or a combination of these) with the risk of side effects and complications. There is still uncertainty regarding the timing, type of plasma exchange, volume and frequency of plasma filtration. Although plasma replacement is considered to be relatively safe, there is still insufficient evidence to support its inclusion in sepsis treatment protocols.
Reports of the use of extracorporeal methods in the treatment of patients with severe refractory systemic inflammation provide evidence of decreased levels of inflammatory biomarkers, improved hemodynamic parameters, and decreased organ failure. However, according to the results of randomized clinical trials, extracorporeal therapy does not affect clinical outcomes, and in some even increases mortality. To clarify the effectiveness of extracorporeal therapy, it is necessary to study the mechanisms of interaction of the devices used with target and non-target blood components and large-scale randomized controlled trials assessing the ability of this therapy to improve clinical outcomes.
IDENTIDADE DOCENTE:

Published: March 2024

No campo da Educação, as últimas décadas foram marcadas pelo direcionamento das discussões na formação docente à esfera mais subjetiva, compreendendo o professor não mais como mero reprodutor de lições, mas como indivíduo dotado de especificidades que se torna docente através de processos socializadores na profissão. Desse contexto emerge o conceito de identidade profissional docente (IPD), considerado, em linhas gerais, como o resultado – não fixo, mas dinâmico – da imersão do sujeito na docência. Compreendendo que abordar as identidades de professores sem demarcar a base teórica que sustenta e delineia a definição dessa categoria pode acarretar imprecisões ou descontextualizações, este artigo tem por objetivo discutir a IPD a partir do conceito de identidade, sob as óticas sociológica, psicossocial e profissional. O debate proposto intenciona, dessa forma, contribuir com pesquisas sobre identidade docente, considerando a complexidade desse objeto de estudo e demarcando elementos fundantes das discussões sobre processos identitários de professores.

Trazer à luz das discussões o debate em torno da Educação de Tempo Integral (ETI) é um dos objetivos deste artigo, que se fundamenta num estudo bibliográfico e numa pesquisa de campo exploratória para investigar o que dizem os professores de uma escola de Ensino Fundamental e os professores de uma escola estadual do Ensino Médio do município de Palmas (TO) sobre a educação de tempo integral em seu contexto institucional de atuação. Para isso, foi realizada a análise do posicionamento dos docentes no que tange à vivência e à experimentação na implementação da ETI a partir de aplicação de questionários com perguntas semiestruturadas via plataforma Google Forms confrontando as bases teóricas. O artigo aborda as legislações e políticas públicas brasileiras que garantem a implementação da metodologia de ensino e as percepções dos docentes na prática diária. Os resultados da pesquisa provocam reflexões acerca da temática, demonstrando que é preciso que se consolide na prática o que está estabelecido na legislação educacional brasileira. Embora os professores tragam alguns aspectos e pontos positivos, de modo geral suas percepções remontam à necessidade de efetivação das propostas e leis para que de fato a educação integral se concretize como uma educação pública, gratuita e de formação integral do sujeito no Brasil. Essas reflexões estimulam repensar as políticas públicas, bem como as estruturas físicas, materiais, humanas e pedagógicas das instituições.

Este estudo visa promover um debate mais aprofundado sobre as questões de gênero e sexualidade, analisando os materiais didáticos utilizados por professores da disciplina Projeto de Vida no Ensino Médio de Tempo Integral de uma escola do município de Mossoró (RN). O presente estudo se alinha a uma problematização teórica, reflexiva e político-discursiva com os estudos desenvolvidos na perspectiva pós-crítica, ancorados na Teoria do Discurso de Ernesto Laclau e Chantal Mouffe e em diálogo com o Ciclo de Políticas de Stephen Ball e colaboradores. A análise desses documentos se faz importante principalmente para tentar compreender como essas instâncias estão organizadas, as articulações discursivas, os significantes privilegiados e as intenções postas em um contexto marcado por investidas da globalização neoliberalista, que está cada vez mais invadindo o campo da educação, com discursos sedutores que tentam “vender” suas propostas como eficientes e salvadoras dos problemas educacionais. Em se tratando das questões de gênero e sexualidade, a própria ideia de construção do Projeto de Vida contribui para o apagamento do diálogo sobre as diferenças. Esse debate é fundamental para ampliar as possibilidades de enfrentamento das temáticas de gênero e sexualidade, correlacionando-as com os aspectos pessoais, familiares, escolares, configurando-se como importantes e necessárias para o desenvolvimento dos seus processos de subjetivação.

Tarihi çevrelerde yaşanan silüet değişimi, genellikle değişim ve gelişim olmaktan çok sorun şeklinde ortaya çıkmaktadır. Tarihi çevrede silüet sorunsalı, ulusal ve uluslararası gündemi meşgul eden önemli konulardan biri olarak son yıllarda dikkat çekmektedir. Bu çalışma kapsamında, tarihi silüetlerde yaşanan sorunlar konu edilmiş ve ulusal haberlere yansıyan durumlar dikkate alınarak Türkiye örnekleminde bir araştırma yapılmıştır. Çalışmada; medya aracısı olarak haber kaynakları, -güncel olma ve kültürel miras farkındalığı konusunda etkili olma gibi özellikleriyle- tarihi çevrelerde silüete olumsuz etki oluşturan uygulamaları tespit etmek amacıyla seçilmiş ve bu haberlere ulaşmak amacıyla Google haberler arama motorundan yararlanılmıştır. Google haberler arama motoru üzerinde; “tarihi çevre”, “silüet”, “kentsel görünüm, “kentin genel görünümü” anahtar kelimeleri ile yapılan taramalar sonucunda ilgili haberler tespit edilmiş ve içerik analizi yöntemiyle incelenmiştir. İncelemede; tespit edilen örnekler, koruma ile ilgili hazırlanmış ulusal ve uluslararası belgelerde yer alan silüete etki eden tasarım parametreleri doğrultusunda değerlendirilerek açıklanmıştır. Elde edilen bulgular ışığında silüet konusunda ulusal gündem aktarılmış ve tarihi silüet denetimine eleştirel bir altlık oluşturulmak istenmiştir. Çalışma sonucunda; silüetin üçüncü boyut etkisinin göz ardı edilmesi, silüet denetimindeki belisizlikler ve yönetim karmaşası gibi nedenlerin özgün görünümlerin korunmasında büyük açıklar yarattığı tespit edilmiştir. Ayrıca silüet konusu ile ilgili ulusal ve uluslararası ilkelerin tasarıma etki etmesi ve tarihi dokularda yeni yapıların özgün görünümler üzerindeki etkisine dikkat edilerek gerçekleştirilmesi gerektiğine dikkat çekilmektedir.

This study aims to explore the effect of a comprehensive treatment scheme comprising conservative surgery, postoperative continuous subcutaneous infusion of gonadotrophin-releasing hormone agonist, rehabilitation training, and rivaroxaban on patients with adenomyosis complicated with lower extremity deep venous thrombosis and to provide a clinical reference. The study results showed that compared to the conventional treatment regimen, patients with adenomyosis combined with lower extremity deep venous thrombosis exhibited significant improvements in uterine function, thrombotic status, and coagulation after the combination therapy. In addition, they demonstrated superior nutritional status and a reduced risk grade for malnutrition. Based on these results, we believe that the combination of conservative surgery, postoperative continuation of gonadotrophin-releasing hormone agonist, rehabilitation, and rivaroxaban has higher clinical value in the treatment of adenomyosis combined with lower extremity deep venous thrombosis than the conventional treatment regimen.

To probe the effect of whole-process nutrition management on the nutritional status of patients with esophageal cancer undergoing radiotherapy, 100 patients were allocated to the control group (n = 50) and observation group (n = 50). Patients in both groups underwent routine treatment after admission. The control group adopted conventional nutrition management, while the observation group was given whole-process nutrition management. Compared to the control group, the patient-generated subjective global assessment score in the observation group declined after intervention (P < 0.05). Levels of prealbumin, albumin, transferrin, immunoglobulin A, immunoglobulin G, immunoglobulin M, CD3+, and CD4+ in the observation group were elevated compared to the control group after intervention (P < 0.05). According to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, the observation group exhibited higher scores in the aspects of family understanding and cooperation, mental condition, appetite, daily life, and sleep quality than the control group after intervention (P < 0.05). Furthermore, the incidence of adverse reactions in the observation group was lessened compared to the control group (P < 0.05). Hence, implementing whole-process nutrition management in patients undergoing radiotherapy can promote their nutritional status and quality of life.
Hexachlorobenzene as a differential modulator of the conventional and metronomic chemotherapy response in triple negative breast cancer cells

Aim: Triple negative breast cancer (TNBC) is usually treated with high doses of paclitaxel, whose effectiveness may be modulated by the action of environmental contaminants such as hexachlorobenzene. High doses of paclitaxel cause adverse effects such as low cellular selectivity and the generation of resistance to treatment due to an increase in the expression of multidrug resistance proteins (MRPs). These effects can be reduced using a metronomic administration scheme with low doses. This study aimed to investigate whether hexachlorobenzene modulates the response of cells to conventional chemotherapy with paclitaxel or metronomic chemotherapy with paclitaxel plus carbachol, as well as to study the participation of the MRP ATP-binding cassette transporter G2 (ABCG2) in human TNBC MDA-MB231 cells. Methods: Cells were treated with hexachlorobenzene alone or in combination with conventional or metronomic chemotherapies. The effects of treatments on cell viability were determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and the nuclear factor kappa B pathway participation was evaluated using a selective inhibitor. ABCG2 expression and its modulation were determined by western blot. Results: Results confirmed that paclitaxel reduces MDA-MB231 cell viability in a concentration-dependent manner. Results also showed that both conventional and metronomic chemotherapies reduced cell viability with similar efficacy. Although hexachlorobenzene did not modify cell viability per se, it did reverse the effect induced by the conventional chemotherapy, without affecting the efficacy of the metronomic chemotherapy. Additionally, a differential modulation of ABCG2 expression was determined, mediated by the nuclear factor kappa B pathway, which was directly related to the modulation of cell sensitivity to another cycle of paclitaxel treatment. Conclusions: The findings indicate that, in human TNBC MDA-MB231 cells, in the presence of hexachlorobenzene, the metronomic combination of paclitaxel plus carbachol is more effective in affecting the tumor biology than the conventional therapeutic administration scheme of paclitaxel.
