Role of prophylactic central neck lymph node dissection for papillary thyroid carcinoma in the era of de-escalation
Authors: Pavlidis Efstathios T , Pavlidis Theodoros E
Published: July 2023

It is now well established that the biology of cancer is influenced by not only malignant cells but also other components of the tumour microenvironment. Chronic inflammation and fibrosis have long been postulated to be involved in carcinogenesis. Chronic inflammation can promote tumorigenesis via growth factor/cytokine-mediated cellular proliferation, apoptotic resistance, immunosuppression; and free-radical-induced oxidative deoxyribonucleic acid damage. Fibrosis could cause a perturbation in the dynamics of the tumour microenvironment, potentially damaging the genome surveillance machinery of normal epithelial cells. In this review, we will provide an in-depth discussion of various diseases characterised by inflammation and fibrosis that have been associated with an increased risk of malignancy. In particular, we will present a comprehensive overview of the impact of alterations in stromal composition on tumorigenesis, induced as a consequence of inflammation and/or fibrosis. Strategies including the application of various therapeutic agents with stromal manipulation potential and targeted cancer screening for certain inflammatory diseases which can reduce the risk of cancer will also be discussed.

In this paper, a testing technique based on supply current verifying is presented, for fault detection of analog circuits containing CMOS operational amplifiers. This testing technique is employed and developed to maximize the fault coverage of the circuit under test (CUT) using transient and frequency responses of the supply current. This testing method is based on the over-sighting of the quiescent supply current (Iddq) of the CMOS operational amplifier operating in its quiescent mode and the supply current of the CMOS operational amplifier used as a Sallen-Key band pass filter in the AC and transient operating domains. The faults investigated in our study are of bridging and open circuit types that occur at the CMOS transistor level. The Pspice software was used for the CUT simulation by applying Monte-Carlo analysis in faulty and fault free conditions. Test parameters are extracted and selected to be used as input features of our classifier.

Authors:   Birla Institute of Technology, Kumari Sakshi , Gupta Vibha R. ,   Birla Institute of Technology
Published: July 2023

This paper presents a laminated paper-based Planar Inverted F Antenna (PIFA) for wireless body area network (WBAN) applications. The major challenges like providing adequate thickness, uniformity of surface, and water wet ability associated with paper substrate have been transcended in this antenna design by laminating the substrate with a transparent sheet. The simulated and measured reflection coefficients of the fabricated antenna in free space and on human arm are remarkably good, validating the prototype’s utility. It can operate effectively in GSM, WMTS, GPS, DCS, ISM, WiMAX, HIPERLAN, WLAN, and UWB frequency bands with S11 less than -10 dB and the gain ranging from 0.94 to 9.53 dB (free space) and 1.03 to 6.07 dB (on-body). The electrical size of the proposed antenna is 0.16 λg x 0.12 λg at 0.7 GHz with a group delay below 2.3 ns over the desired frequency bands. The performance characteristics are also investigated on-body and it encompasses most of the desired frequency bands for the body area network. This paper also analyses the specific absorption rate (SAR) of the designed antenna by placing it on a tissue-layered human arm model, which is 0.64 Watt/kg, complying with the SAR safety guidelines.
The Effect of Mindfulness-Based Interventions on Insecure Attachment Styles
Authors: Zhong Yuling
Published: July 2023

Mindfulness has been spreading rapidly in the study and practice of Western psychology. Large amounts of research have shown that mindfulness training is effective in improving a variety of symptoms associated with physical and psychological disorders such as chronic pain, anxiety and depression. Moreover, mindfulness training is also proven to improve the level of dispositional mindfulness as well as psychological well-being. Since individuals with insecure attachment styles who have either high anxiety or high avoidance in intimate relationships were found to have more severe psychological anguish, such as depression and anxiety, mindfulness training may be applied to alleviate the negative effects brought by insecure attachment styles. This article is aimed at reviewing related studies on attachment and mindfulness and exploring how the negative effects of insecure attachment can be alleviated by the application of mindfulness training. The author came to the conclusion that the negative effects of insecure attachment on individuals’ well-being and emotion regulation can be alleviated by mindfulness-based interventions. In addition, the author predicts that mindfulness-based interventions can effectively improve attachment insecurity, but more meta-analyses are needed.

Authors: Velasco Nicolas , Buteler Laura
Published: July 2023

El presente trabajo investiga sobre la incorporación de los resultados de investigación en didáctica de las ciencias en las clases de las asignaturas disciplinares de los Profesorados de Física de Nivel Superior de la Provincia de Córdoba. La información se obtiene de las respuestas a un cuestionario por parte de los docentes encargados de los espacios disciplinares de física de los Institutos de Enseñanza Superior de la Provincia de Córdoba y de entrevistas focales a cuatro de ellos. Del análisis es posible advertir que: 1) los docentes reconocen algunas potencialidades de abordar la Naturaleza de la Ciencia en la enseñanza, pero estos contenidos siguen teniendo un lugar secundario en las propuestas. 2) Los docentes dicen frecuentemente problematizar el contenido utilizando múltiples recursos. 3) Los trabajos prácticos de laboratorio como investigaciones son usados con poca frecuencia. En general los docentes utilizan los laboratorios como experiencias demostrativas o para ilustrar la teoría. 4) Los docentes mencionan que usualmente fomentan la participación de los estudiantes y sus aportaciones son escuchadas, pero pocas veces se promueven instancias desde las cuales surjan nuevos aprendizajes a partir del trabajo en pequeños grupos. Finalmente, 5) En relación a la frecuencia con la que los docentes trabajan desde las ideas previas de los estudiantes, se ha encontrado que existen dificultades semánticas sobre qué es una idea previa o un modelo alternativo y lo que es un conocimiento normativo no aprendido
A Rare Periprosthetic Knee Joint Infection With Clostridium perfringens, the Result of 2-Stage Exchange Treatment: A Case Report and Review of Current Literature
Authors: Stokey Phillip , Canova Tyler , Elsaghir Hend , Hanna Maged
Published: July 2023

Prosthetic joint infections (PJIs) commonly result from aerobic gram-positive organisms and can lead to detrimental outcomes. However, it is rare for Clostridium perfringens to cause a PJI. Owing to its rarity, current literature lacks a comprehensive guide for the proper management of these PJIs. We report on the case of an 80-year old man who presented to our institution with concerns for sepsis secondary to a PJI with C. perfringens 25 years status post total knee arthroplasty. The patient was managed with two-stage revision and exchange. After stage one, the patient developed cholecystitis, which has been reported in prior cases of PJI due to C. perfringens. After concerns for sepsis had resolved and stage 1 was complete, the patient was managed with 6 weeks of IV antibiotics. Treatment was directed at gram-positives with IV vancomycin along with anerobic coverage determined by anerobic susceptibility testing. After the second stage, the patient was discharged with 3 months of oral antibiotic therapy. At the final 1-year follow-up, the patient was doing well without residual infection. This report reviews previous evidence on the management of C. perfringens PJI and presents a case demonstrating the successful diagnostic, surgical, and antimicrobial management of a PJI with C. perfringens.
A NEW PHILOSOPHY FOR SUSTAINABLE CONSUMERISM
Authors:   Business Consultant, Auckland, New Zealand, THARIAN Bibin
Published: July 2023

With growing awareness of unsustainable practices, communities are forcing businesses and governments to take serious steps towards sustainability. Microplastics enter the food chain and eventually reach humans. The threat of global warming and recurrent climate disasters necessitate immediate action. However, all governments and corporations rely on an ‘increase in demand’ as a growth metric, which prevents them from doing anything meaningful to ensure our planet’s long-term viability. Against the above paradox, this article explores a compromise between sustainability, consumption, and economic growth. It is a theoretical framework for proposing a solution in which businesses can expand in tandem with our planet’s long-term future or a glance through the areas where the Keynesian economy can coexist with environmentalists’ concerns. The proposed framework claims significance in terms of practicality than the perfection of a solution.

JOURNEY THROUGH THE PAST: A CONTINUITY OF ECOLOGICAL CHALLENGES
Authors:   CERGAM, Aix-Marseille University, France, PACHÉ Gilles
Published: July 2023

While ecological challenges are more and more systematically placed at the heart of the news, with the multiplication of activist groups carrying out sometimes violent actions of protest, it is usual to consider that environmental degradation is relatively recent. It is true that the first alarmist reports date from the early 1970s. However, numerous historical studies underline that ecological challenges were extremely significant as early as the Middle Ages in Europe, which forced political authorities to intervene to successfully limit environmental degradation in cities. A review of history sheds light on current issues, highlighting the importance of political interventionism to meet ecological challenges.

Communicative-Language Assessment Approach and the Effect of Technology in Designing Speaking Rubrics
Authors: Algazzaz Wala Ahmad
Published: July 2023

This paper delves into the complicated realm of communicative language evaluation, intricately examining the multifaceted impact of technology on the construction of speaking rubrics. At its core, the assessment technique for communicative language staunchly upholds the notion of language as a vibrant tool of communication. It emphasizes the imperative to assess language learners based on their ability to effectively engage in real-life linguistic interactions within the target language. In stark contrast to the mere regurgitation of grammatical rules and vocabulary, this method underscores the contextual employment of language skills. In turn, speaking rubrics are language-evaluation instruments that are used to measure learners’ verbal skills. They are intended to test students’ abilities to use language in context and communicate successfully in the target language.

Authors: Alhumud Manal , Moore Simon , Morgan Kelly
Published: July 2023

OBJECTIVE: To estimate the prevalence and socio-economic determinants of energy drink (ED) consumption and related health outcomes in Riyadh, Saudi Arabia.

METHODS: A self-report survey was used to collect data from 2,024 students (aged 13-20 years). Logistic regression was used to determine the relationship between ED consumption, diet and health-related outcomes.

RESULTS: In total, 54% of young people reported ED consumption at least once and 25.5% at least weekly. The most common (38.65%) reason for ED consumption was the enjoyable flavour. Male students reported higher ED consumption compared to females (OR = 1.26, 95% CI 1.08 to 1.46). ED consumption was associated with an unhealthy diet (OR = 1.69, 95% CI 1.53 to 1.87), tobacco use (OR = 5.91, 95% CI 3.47 to 10.07), poor quality sleep (OR = 0.73, 95% CI 0.47 to 0.99). Those who regularly ate breakfast were less likely to report ED consumption (OR = 0.89, 95% CI 0.83 to 0.95).

CONCLUSION: More than 1 in 2 young people reported ED consumption among a sample of Riyadh-based students. Consumption was found to be associated with a poor-quality diet and negative health outcomes. Findings suggest that there is a public health need to reduce the consumption of EDs among this population.

The purpose of this study was to find out how the fulfillment of religious education learning services at Elementary School (SD) Inpres I Nimbokrang 2, Nimbokrang District, Jayapura Regency, Papua, Indonesia, is in accordance with each student’s religion from an early age in the context of instilling the values of religious moderation in a multicultural society. This study uses descriptive qualitative methods so that researchers can see directly the problems that occur in the field with data collection techniques in the form of observation, interviews, and documentation. The results showed that even though the school did not provide teachers for one of the students’ religions due to limited human resources, namely Buddhism, the school worked closely with non-formal educational institutions at the Vihara. The attitude of religious moderation can be realized through fulfilled religious education. Such as an understanding of living side by side amidst cultural differences in the school environment and the community environment, applying an attitude of tolerance, loving one another, and understanding the concept of karma. Strengthening the values of religious moderation needs to be taught to children from the elementary school level on so that they are able to behave moderately and prevent conflicts that ignite due to cultural, ethnic, and religious differences in the future when they go through the stages of maturation.

A Study on the Formation Process and Characteristics of Korean TV Dramas: Focusing on Soap opera
Authors:   The Academy of Real Korean History, Lee Jiyeon
Published: July 2023

This study examined the formation process and historical trends of Korean television dramas, particularly morning dramas, and explored the impact and characteristics of changes in the media and broadcasting environment. Soap opera, similar to other daily dramas, serve as a vivid documentation of modern Korean life. These dramas are composed of everyday events that are realized through personal narrative relationships. They have evolved through the reenactment of significant family-related rituals and private events, such as birth, death, romance, marriage, and divorce. However, by the end of October 2021, Soap opera had disappeared from Korean society. The reasons for this are: First, weakening revenue and low ratings for content distribution due to economic burdens from the mid-2010s; Second, production burden due to low profitability of Soap opera;; and Third, viewers' boredom and TV viewing platform for the unreasonable development of last-minute dramas. lack of competitiveness due to environmental changes. K-drama is a symbolic means to feel familiarity and liking for Korean society and culture, and this serves as an opportunity to look forward to a more contextual analysis and multi-layered thinking on the phenomenon of transnational cultural distribution.
The Ancient Liaodong Recorded in the Sagi (史記)
Authors:   The Academy of Real Korean History, Choi Won-Tai , Jung Ahm
Published: July 2023

The location of the Liaodong (遼東) in ancient China was different from that of today. The Liaodong at the time was a major indicator of the western boundary of Old Joseon (古朝鮮), the first Korean nation. According to literature including Sagi (史記), Liaodong in ancient was a place name first used to point to the Far East of China. However, over time, it has also apply to name of the administrative district and princely states in China. Example of the former both includes Liadong-gun (遼東郡), an administrative district established after the Yan (燕) defeated Dongho (東胡) and Old Joseon, built their Great Wall, and is Liaodong-gun, an administrative district established during the Qin (秦) and Western Han (西漢) period. Example of the latter was Liaodong-guk (遼東國), an princely states established by dividing the land of the former Yan in the early Han Dynasty.
The Liaodong before invasion Dongho and Old Joseon by Jingae (秦蓋) (approximately BC 300) seem to have pointed to outside the eastern border of the Yan, that is, the area between the Chisu (治水) River (currently Yeongjeongha 永定河) and the Gosu 沽水) River (currently Jobaekha 潮白河). After the invasion of Jingae, it went beyond the region and pointed to the east part of Yusu (濡水) River (currently Nanha 灤河). The Liaodong-gun which was established during the Jingae period, the Liaodong-gun which was established during the Qin Dynasty, and Liaodong-guk which was established during the Western Han were geographically overlapped on the same region. Therefore, we argue that the Liaodong from the ancient Yan to the Western Han period was a region limited to the east part of the lower stream of Yusu (濡水) River (currently Nanha 灤河).

In order to be able to carry out their activity and at the same time comply with the restriction measures imposed by the governments of the world with the aim of limiting the spread of the novel coronavirus, economic entities tested their resilience and adaptability, using much more the digital technology. Whether they were prepared for this purpose or not, it seems that the pandemic caused by the novel coronavirus has amplified the digitization process. In this context, the purpose of our study is to identify whether digital transformations have impacted sustainability and the transition to a green economy. Our sample consists of the entities listed at the Bucharest Stock Exchange (BSE) that published their annual reports in the period 2019-2021. Thus, with the help of the NVivo program, we extracted the keywords found in the European Green Deal. Then, with the help of the RapidMiner program, we were able to analyze the annual reports published in the three years to identify, based on the selected keywords, the green initiatives undertaken by the entities from our sample. The results reflect the fact that, in pandemic times, annual reports present information more and more succinctly, and weaker financial results are embellished by focusing on the positive aspects undertaken, such as the efforts started in the sphere of sustainable development.
COMPUTATIONAL STUDIES OF HELICOPTER AERODYNAMICS
Authors:   Georgia Southern University, Statesboro, USA, ILIE Marcel , Semenescu Augustin ,   University Politehnica, Bucharest; Academy of Romanian Scientists
Published: July 2023

The present research concerns the helicopter aerodynamics and the blade-vortex interaction phenomenon. The computational studies are carried out using the large-eddy simulation approach for subsonic incompressible flow of Reynolds number Re=1.3x106. The helicopter aerodynamics is dominated by the blade-vortex interaction (BVI) phenomenon which is responsible for noise and vibrations. During the helicopter flight, a tip-vortex filament is formed and its interaction with the advancing blade causes the blade-vortex interaction phenomenon. The study shows that the blade-vortex interaction causes oscillations of the aerodynamic coefficients. Due to the turbulence phenomenon, the oscillations exhibit a non-linear behaviour.
NEW MEDICAL APPROACHES IN CROHN’S DISEASE TREATMENT
Authors:   Colentina Clinical Hospital, Bucharest, Romania, MIRON Miruna-Ioana
Published: July 2023

Crohn's disease is a lifelong, relapsing systemic inflammatory disease of unknown etiology, mainly caused by an impaired immune response, characterized by chronic inflammation of any part of the gastrointestinal tract, with an increasing incidence worldwide. This disease is associated with multiple extraintestinal manifestations and patients frequently present persistent diarrhea, abdominal pain and weight loss. It affects people of all ages, but its onset generally occurs at a young age. Several triggers have been implicated in the etiopathology of Crohn's disease, including a dysregulated immune system, an altered intestinal microbiome, genetic susceptibility and environmental factors, but the main cause of the disease still remains an enigma. Due to its debut at a young age, in most cases, a long-term and early established treatment is undoubtedly required to prevent its progression with multiple intestinal and extraintestinal complications. Nowadays, novel biologic therapies or small-molecule drugs may deeply change the innate history of this pathology and could also decrease the rate of complications and the need for surgery. In order to establish the proper diagnosis, endoscopy with the histological evaluation of biopsy specimens represents the most reliable method, even if less invasive biomarkers are being developed. Crohn's disease is a comprehensive disease and the treatment should be adapted to each patient’s underlying pathogenetic mechanism.

Published: July 2023

Limanların askeri amaçlı kullanımları zaman içinde deniz üssü tabirini ortaya çıkarmıştır. Nitekim askeri deniz üsleri genel anlamda gemilerin imal, bakım, onarım ve barınma ihtiyacını karşılayan, uzak bölgelere etkili harekât yapıl-masını sağlayan ve donanmanın gerek asker gerekse lojistik ihtiyaçlarına cevap verebilen yerler olarak değerlendirile-bilir. Bu noktada Sinop limanı, coğrafi ve stratejik olarak son derece elverişli özelliklere sahip olması itibariyle Ka-radeniz’in en iyi deniz üsleri arasında yer almaktadır. Osmanlı Devleti zamanında Sinop’un askeri bir deniz üssü olarak en faal kullanıldığı dönem şüphesiz XVIII. yüzyıldır. Zira bu dönemde Osmanlı Devleti’ni sınırlarının ötesinde en çok uğraştıran sorunların başında Rusya ile girişilen mücadeleler gelmektedir. Sinop’un başta Kırım olmak üzere ülkenin kuzeyine yakınlığı sebebiyle Anadolu’dan gelen asker, mühimmat ve zahire naklinin Sinop'tan deniz yolu ile yapılması ve Osmanlı donanmasının her türlü ihtiyacını karşılayacak kapasitede olması burayı Osmanlı-Rus savaşlarında ön plana çıkarmıştır. Neticede Sinop, XVIII. yüzyılda gerek stratejik konumu ve bünyesinde barındırdığı doğal korunaklı limanları gerekse tersanesi ile Osmanlı Devleti için önemli bir askeri deniz üssü konumunda olmuştur denilebilir.

A researcher-structured questionnaire was used to assess whether students in four schools in the metropolis had been exposed to ACEs. A 10-item instrument‑ the Adverse Childhood Experience Questionnaire (ACE‑Q) by Felitti et al. (1998) and a self-report scale‑ Rosenberg Self-Esteem Scale (RSES) (Rosenberg, 1965) were adopted to collect data on the students’ ACEs and self-esteem respectively. Results showed that there is a moderate negative relationship between adverse childhood experiences and students’ self-esteem (R=-.484). The coefficient of determination (.234) shows the variation in students’ self-esteem due to adverse childhood experiences. Furthermore, the results showed that gender has a low moderating effect on the association of ACEs with self-esteem among students (R=-.485). It was recommended, among others, that the government should ensure that policies are formulated to reduce the incidence of ACEs and the harms associated with ACEs when they occur. It is important that schools provide adequate counselling services to students who have low self-esteem as a result of ACEs. Teachers and school psychologists should also make a conscious effort to give adequate social and psychological support to children who are prone to low self-esteem as a result of prior exposure to ACEs.

The objective of this study was to determine how the effect of supplier development and proactive product recall on quality performance. The study used a reliability test and regression analysis using SPSS version 22. The data was collected from 139 supply chain professionals working at various organizations located in Karachi, Pakistan. A Likert scale questionnaire was used to gather the research's primary data. The data collected was then measured using a statistical technique. This study suggested that the quality performance of the firm is positively affected by proactive product recall. In comparison, quality performance does not significantly impact supplier development. This study helps managers in management practice in managing the quality performance of firms. It also helps them to understand the critical role of quality performance. It is recommended that the data be taken from more respondents, increasing its reliability. Due to the questionnaire design, answer errors can be found while collecting the data, and it could be overcome by gathering data through interviews with preferred supply chain professionals face to face.

A genetically diverse condition, maturity-onset diabetes of the young (MODY), frequently develops before the age of 25. MODY is caused by disease-causing sequence variations in the
PAX4 gene, which is found on chromosome 7q32.1. Additionally, it has also been observed that variants in
PAX4 have also been associated with neurodevelopmental disability. Whole exome sequencing (WES) followed by Sanger sequencing was performed for all the available affected and unaffected members of the family. Data analysis revealed a novel heterozygous nonsense variant (c.61C>T; p.Gln21*) in the
PAX4 gene in the affected individuals, which segregated perfectly with the disease phenotype. The present study adds to the
PAX4 mutation spectrum and reports on the first case of MODY associated with neurodevelopmental disorders in humans.

The new ways of interacting with computers, smartphones, and other devices have brought new challenges, such as the need to ensure that different types of users can easily use the same system. Adaptive User Interface (AUI) systems have been recognized as a solution to this matter. They change the user interface to better meet the needs of different users. However, developing such systems is not trivial. It is necessary to capture the users’ characteristics and preferences and constantly adapt the system accordingly. In this paper, we discuss the use of ontologies to support the development of AUI systems. We argue that by providing structured knowledge about such systems, ontologies help understand how they work and offer a basis to structure them, identify the necessary adaptations and implement mechanisms to make them happen in run-time. We have explored the use of ontologies from an ontology network (i.e., networked ontologies) to develop a social network about academic subjects that automatically adapts its interface according to the low vision and colorblind user’s needs and usage characteristics. This exploratory study showed that using networked ontologies to develop an AUI system is useful and feasible. The ontology was useful at the conceptual level by serving as a basis to define the system’s structural model and at the operational level by providing the semantics used in a reasoning engine to adapt the UI at run-time. The first version of an ontology-based process to guide the development of AUI systems emerged from this experience and it is also presented in this paper.

In the context of integrated pest management, the compatibility between the products used and even with the natural enemies of crop pests should still be elucidated. In this study, interviews were done with about 60 coffee growers to assess the use of pesticides in the protection of coffee berries. Then, in vitro tests were used to evaluate the effects of extracts of the seed powders of Thevetia peruviana, Azadirachta indica, the chlorpyriphos-ethyl insecticide and the chlorothalonil + dimethomorph fungicide, on the development parameters of the entomopathogenic fungus Beauveria bassiana, the natural enemy of the coffee berry borer, Hypothenemus hampei. The said tests consisted of the method of poisoning the culture medium with pesticides, observation and counting of spores under the optical microscope. The analysis of the collected data showed that depending on the type and severity of the pest pressure, growers apply several types of mainly chemical pesticides. Among the pesticides tested, extracts of T. peruviana, A. indica and chlorpyriphos-ethyl considerably reduced the development of B. bassiana. These results show that in crop protection, the use of biological or chemical substances should be done in a judicious way, to ensure the conservation and the valorization of natural enemies of phytosanitary pressures.
Gamma Irradiation as Tool for Mutation Breeding in Wheat
Authors: von Well Eben , Booyse Mardé , Fossey Annabel
Published: July 2023

Mutation breeding is used to modify a specific character of a plant, while all other characteristics remain the same. Adaptation obtained through mutation breeding to biotic (disease and insect pest resistance) and abiotic (aluminum toxicity, drought, high temperature, salt tolerance) stresses leads to better harvest growth, yield and quality. The main aim is to promote the efficiency of energy conversion into growth as a tool for the prediction of the optimal gamma irradiation dosage for mutation breeding in wheat. Cytogenetic analysis done on Triticum turgidum ssp. durum cv. Orania will be presented in the form of nucleolar activity to determine incomplete mitosis as well as in the form of bridges, fragments, micronuclei and ring chromosomes that will be compared with the efficiency of energy conversion into growth. Studies done on two Triticum aestivum cultivars, namely Ratel and Kwartel, included observation of double spikes, reduction in fertility and determination of the window for the optimal dosage for mutation breeding. Cultivars/breeding lines that are more resistant to gamma irradiation have a wider window for the optimal dosage range for mutation breeding. The ideal gamma irradiation dosage range for the three cultivars, namely, Orania, Ratel and Kwartel were determined.
Fluidization Behavior of Binary Mixtures of Coal in a Top-Fed Bubbling Fluidized Bed Gasifier
Authors: Can Sivri Ali
Published: July 2023

Bubbling Fluidized Bed Gasifier (BFBG) technology is an efficient and economical way of producing syngas from various feedstocks, such as coal, biomass, and municipal waste. However, the prediction of the gasification process inside the BFBG is quite complex due to many factors, including multiphase flow hydrodynamics. This study analyzed the hydrodynamics of a bench-scale top-fed bubbling fluidized bed coal gasifier with sand or glass beads used as bed materials at different bed aspect ratios. Two separate test rigs were built with the same dimensions for cold flow (without reaction) and hot flow (with reaction) studies, respectively. The cold flow test rig was used to investigate the hydrodynamics of BFBG fluidization. Bed pressure drop, minimum fluidization velocity, and mixing were analyzed in the test room conditions. Following that, gasification tests were carried out in the hot flow BFBG test rig with a novel feeding system using the optimum hydrodynamical parameters determined from cold flow analyses. Results showed that syngas was successfully produced at an adequate composition. This study contributes to a better understanding of the fluidization hydrodynamics of the binary coal and bed material mixtures in a top-fed BFBG for a more optimum gasification process and easier operation of the BFBG.
