Modelling the integration of bagasse pyrolysis into sugar mill energy systems
Authors: Matsueda Yu , Sheehan Madoc , Gilberd Jonathon
Published: October 2024

Pyrolysis degrades biomass under low oxygen conditions to produce an energy-rich gas, bio-oil, and carbon-dense biochar. The resulting bio-oil and gas can be combusted for high energy production, while biochar is a high-value product with potential as a fertiliser and soil amendment product. However, very few studies have been on integrating pyrolysis into the sugar mill energy system. This study aimed to model the integration of bagasse pyrolysis into an energy system based on Victoria Mill. The model was well-validated from previous literature on bagasse pyrolysis and mill system data. The pyrolysis unit’s operating conditions were optimised for steam production, carbon emission reduction, and product value, resulting in 20% less steam production, 16% reduced CO2 emissions, and 76% higher economic profit than current operations. Full steam production could be maintained by bypassing 30% of the bagasse to the pyrolysis unit and 70% directly to the boiler. This configuration led to 12% reduced CO2 emissions and 32% greater economic profits when compared to the current process. Overall, this research showed that the integration of bagasse pyrolysis into sugar mill energy systems has potentially substantial benefits, and its adoption in sugar milling deserves careful analysis.
Novel Methodology to Detect Non-Compliant Usage of Seat Belt in a Passenger Car
Authors: Rajakumaran Sriram , Jinka Divyajyothi
Published: October 2024

Seat belts are fundamental and legally required safety feature in a vehicle. They are designed to protect occupants from fatality in the event of an accident. Seat belts, if used correctly, could significantly reduce the risk of injury and be lifesaving in accidents of varying severity. There is immense push on the technology front by automotive regulatory bodies and independent organizations like NCAP (New Car Assessment Program) enforcing motor vehicle users to wear safety belts. While there are many technological advancements like Seat Belt Reminder (SBR) system and the importance of seat belt usage cannot be more emphasized, there are still significant passenger car users who do not wear seat belts, for various underlying reasons. This paper lists different possible misuse cases that the occupant can be creative about to not wear the seat belt. We develop a sophisticated methodology that can caveat each misuse case which are not addressed by state-of-the-art techniques. For a given occupant, there is a certain length of seat belt that gets exposed outside the pillar trims while it is deployed, and this length is different when the belt is misused in a non-compliant way. The methodology uses the idea of seat belt length to classify between a use case and a misuse case. The logic derived from this methodology would be fed to the ECUs of vehicle components and alert the system and occupant about the non-compliant usage of seat belts.

Development of Oxidation Resistance Coating on Tungsten Based Electrical Contacts of Automotive Disk Type Electromechanical Horn
Authors: Dr. Shirish C. Bali  , Vaibhav Bhavsar
Published: October 2024

In electromechanical horns, electrical contacts made out of tungsten are generally used to connect and disconnect the electrical circuit. Tungsten is used for this application due to its high melting point, high hardness, good abrasion & wear resistance. However, due to tungsten’s poor oxidation resistance, these electrical contacts undergo severe high-temperature oxidation during contact making and breaking. Thus, development of high-temperature oxidation-resistant coatings on tungsten contact under different pack composition such as concentration of master alloy (15 – 40 % Al for aluminizing and 30 - 40% Cr for chromizing), activators (2 - 5 % NaF /NH4F for aluminizing, 2 - 5% NH4I / NH4Cl for chromizing) and fillers (55 – 83 % calcined alumina/ calcined alumina + chromium for aluminizing, 55 – 68 % of standard compound known China clay) at different temperature (750 - 1100 °C for aluminizing, 900-1200 °C for chromizing) for different soaking time (5-15 for aluminizing, 18-24 for chromizing) inside constant hygon (95 % Ar + 5 % H2) environment is attempted. Effect of above-mentioned parameters on coating behaviour such as coating thickness, composition, structure and hardness is reported in this research paper. By optimizing the above-mentioned parameters Aluminizing coating at 750 °C for 10 h soaking time with 15% Al powder source as master alloy, 3 % NaF as activator and 82 % calcined alumina as filler resulted into 15 - 20 μm coating thickness, single phase – WAl3.5 structure throughout coating having average micro-hardness of 550.4 HV0.05. Chromizing coating at 1200 °C for 24 h soaking time with 40 % Cr powder source as master alloy, 3 % NH4I as activator and 57 % China clay as filler resulted into 25-30 μm coating thickness, gradient phase change of structure from Cr9.6FeW0.9 to Cr6.5Fe5.3 from outer to inners side of coating having average micro-hardness of 751.5 HV0.05

Geometrical Characteristics of Kerf width on Titanium Alloy by Abrasive Water Jet Machining
Authors: Dr. U Ashok Kumar  , P. Anunay  , G. Sai Seemanth  , M. Bala Gangadhar Tilak
Published: October 2024

This study investigates the effect of abrasive water jet (AWJ) machining parameters on the kerf width geometric characteristics of Ti-alloy workpieces. Taguchi's design of experiments were used to evaluate the influence of standoff distance, abrasive mass flow rate, and traverse speed on kerf width The results indicate that nozzle traverse speed is the most significant factor affecting the top kerf width. This suggests that controlling the traverse speed is crucial for achieving desired kerf width and maintaining machining precision. Water pressure emerges as the second most significant factor influencing the kerf taper angle and the surface roughness. This implies that water pressure plays a dual role in shaping the kerf geometry and affecting surface quality. The abrasive flow rate is found to have the least significant impact on the kerf characteristics. This suggests that the erosive power of the AWJ jet is primarily governed by the water pressure and the traverse speed, while the abrasive mass flow rate plays a secondary role. Overall, the study highlights the importance of understanding the interplay between AWJ process parameters and their influence on kerf geometry and surface quality. Optimizing these parameters can lead to improved machining precision and enhanced product quality in Ti-alloy manufacturing.

Authors: Damayanti Cory Nelia , Hannan Mujib , Hidayat Syaifurrahman
Published: October 2024

Leprosy is still a health problem in endemic countries, one of which is Indonesia. It is caused by the lack of information about leprosy, which affects the self-care management of leprosy sufferers to increase the risk of leprosy severity. Leprosy is a chronic granular infection caused by the obligate intracellular organism M. leprae. These germs initially attack the peripheral nervous system, then the skin, mucosa, respiratory tract, retinal system, eyes, retina, bones, and tissues. This study aims to determine the relationship of information on self-care management in leprosy patients in the Sumenep Regency. This type of research was an observational analysis using a cross-sectional study approach. The population was 32 respondents, with a sample of 30 respondents. The sampling technique used simple random sampling. Data collection used a questionnaire, and data analysis used Rho Spearman with a significance level of p<0.005. The analysis result obtained significance, or the value of information availability (0.000) was much more standard significant than 0.05 or (p < a), then H0 was rejected, and H1 was accepted, which means that there is a relationship between information and self-care management in leprosy patients. Information can affect self-care management in leprosy patients. Self-care management has an important role in preventing the severity and transmission of leprosy. With enough information, leprosy patients can carry out good self-care- management and reduce the impact of leprosy effectively.

Authors: Hazzard Iyawnna , Batiste Maryann , Luo Tianyu , Cheung Cyrus , Lui Forshing
Published: October 2024

Alzheimer’s disease (AD) is the leading cause of dementia worldwide. The disease is characterized by the abnormal accumulation of amyloid β (Aβ) protein creating neuritic plaques, hyperphosphorylated tau (p-tau) protein forming intracellular tangles, and neuronal degeneration. Pathological changes related to abnormal Aβ and p-tau accumulation may begin more than fifteen years before the clinical diagnosis of AD is made. The glymphatic system is the brain’s waste clearance pathway that prevents the accumulation of these abnormal proteins and macromolecules. Glymphatic clearance is negatively affected by physiological conditions such as sleep deprivation, and pathological conditions such as traumatic brain injury and hemorrhagic strokes. These physiological and pathological conditions are strong risk factors for AD. In conclusion, impaired glymphatic clearance is an important pathogenetic mechanism for AD.
Quasi-resonant Zero Voltage Switching Modified Boost Converter
Authors: Himmelstoss Felix A.
Published: October 2024

To reduce the switching losses in a DC/DC converter the quasi-resonant concept can be applied to the converter. With an additional resonant capacitor and an additional resonant inductor, the voltage across or the current through the electronic switch is influenced, so that the switching of the transistor can be done at zero voltage or zero current. The zero voltage switching concept is applied to the modified Boost converter. The modification concerns the position of the bulk capacitor. It is not connected between the output terminals but between the positive input and output connectors. This reduces the voltage stress of the capacitor and avoids the inrush current when connected to a stable DC grid or large batteries. The converter is explained step by step with the help of equivalent circuits and calculations. A very instructive method to analyze resonant circuits is the uZi diagram which is also applied. LTSpice simulations are used to prove these considerations.

Authors: Adam Adil , Kacar Firat , Uzunoglu Cengiz Polat
Published: October 2024

The growth of using medium-voltage drivers (MVDs) to control medium-voltage motors has led to more complicated designs to cover the market demand. Multi-phase transformers (MPT) are one of the most preferred components for AC-DC-AC converters. MPT in MVD systems has essential functions: harmonic filtering between the grid and rectifier, Isolation between the grid and rectifier, converting voltage to suitable voltage for the rectifier, and preventing block common-mode voltages, which could cause failure in motor winding insulation. MPTs are critical to motor drivers because of their pure sine wave, low THD, grid isolation from the motor, efficacy, and cost-effectiveness. This work addresses the configuration, winding turn ratios, selection factors, and calculations of power, weight, and design procedure for shifting transformers. The proposal design is confirmed by simulation results, which support the experimental studies validated by different load levels. The result determines the inductance value for cost-effectiveness, low-harmonics, and power factor improvement. This work provides an experimental method to specify the IPT inductance value, which improves the power rating and reduces the THD. Mathematical specification, an experimental method, was applied to calculate the optimal value of the IPT inductance. The simulation and experimental results analysis were studied and verified. The optimal value of inductance obtained by the simulation result is 25mH; at this value, the THD equals 4.6%.

The increasing prevalence of Learning Management Systems (LMS) in higher education worldwide highlights the importance of investigating LMS effectiveness. This is especially pivotal for the successful execution of the national agenda promoting globalized online education. Given the near-mandatory nature of LMS adoption in higher education, the emphasis shifts from the intention to use the LMS to understanding how the utilization of LMS contributes to its effectiveness. The premise is that students who actively engage with the LMS are likely to perceive it as an effective tool for their educational needs. Therefore, this study aims to construct a model for LMS effectiveness within Malaysian universities, utilizing the Technology Acceptance Model (TAM) with LMS use as the mediating factor. The fundamental TAM factors, along with two additional elements: student self-efficacy and student attitude have been employed as predictor variables. Our Partial Least Squares analysis results reveal a noteworthy mediating role of LMS use in the relationship between student self-efficacy and LMS effectiveness, as well as between student attitude and LMS effectiveness. Moreover, the impact of LMS use on LMS effectiveness is found to be substantial.

Investigating the assessability of speaking proficiency in a group discussion context
Authors:   Meiji University, Garside Paul
Published: October 2024

The main purpose of this exploratory study was to attempt to measure the construct of speaking proficiency in a group discussion context. Although peer-discussion activities are commonly used in ESL/EFL classrooms, little is known about how to adapt this format for testing purposes and whether it can be done so reliably. In this study, an analytic rubric was used to assess the proficiency of Japanese university students during group discussions. Rasch (MFRM) analysis was then conducted to investigate the extent to which the students, raters, and category items (i.e., subcategories of the rubric) fit the model. Results showed that although the raters differed in terms of severity, they maintained internal consistency, therefore allowing MFRM to control for this disparity. Following this procedure, students could be separated into approximately three levels of proficiency. Furthermore, all category items fit the model sufficiently well to conclude that a single construct was being measured. These findings support the idea that group oral testing can be conducted reliably as an aspect of L2 speaking assessment. Keywords: group speaking assessment, Rasch analysis, facets, MFRM
FEATURES OF THE MECHANISMS OF PSYCHOLOGICAL COUNSELING INDIVIDUALLY AND IN SMALL GROUPS
Authors:   Mirzo Ulugbek National University of Uzbekistan Jizzakh branch of Kazan Federal University co-educational, Uzbekistan, Makhmudova S. Z.
Published: October 2024

Psychological counseling is the process of helping an individual in search of resolution for his difficulties adjust to the demands of life situations and make adequate decisions. Adjustment should be voluntary and painless for the client. Psychological counseling should not be confused with therapeutic intervention, in which the individual is supposed to return to a normal condition after being under stress due to negative changes in his life situation. Instead of changing the condition of the individual, counseling focuses on the efforts to ensure harmonious matching of the individual’s level of functioning with age-appropriate requirements. In this sense, counseling is a frontier between psychotherapy and pedagogical intervention. The concept of the counseling mechanism is popular in studies of educational, social, and psychological counseling. It includes features of individuals, conditions, and processes that define the role of counseling in bringing about changes in personal development and behavior. The content of mechanisms reflects the structure and functional aspects of a phenomenon under study, the latter being viewed as a system. Psychological counseling is a complex multi-level system reflecting various social, psychological, and personal relations. In broad terms, it includes a subject, object, conditions, and processes of interaction between the counseling agent and the counseling recipient. Multiple approaches may be employed to conduct psychological counseling. They will be reviewed and analyzed here in regard to their psychological basis and the features of their application. Three of the most significant approaches are the psychodynamic, cognitive-behavioral, and humanistic. Significant attention is focused on the first two approaches since they are the most popular in the perspective of the countries of the former Soviet Union. As a basis of the psychodynamic approach, the role of the unconscious is emphasized, and it utilizes defense mechanisms. Numerous psychotherapeutic techniques are developed, mainly of a verbal nature, designed to bring the unconscious content of conflicts and desires into consciousness. These techniques are used both in monological and dialogical forms. An essential part of the dialogical techniques is free association, and a key monological technique is interpretation. The clinical terminology of the psychodynamic approach is extensive and systematically elaborated, including concepts of conflict, drive, impulse, symptom, resistance, transference, counter-transference, interpretation, regret, and gloom. All these concepts were created on the basis of clinical observations of various forms of behavior of subjects and are logically organized in the theory of personality.

Published: October 2024

Kebebasan pers merupakan harapan bagi para pekerja media agar dapat menjalankan tugas dan fungsinya sebagai jurnalis sesuai dengan amanat negara dalam undang-undang pers. Namun, kasus-kasus kekerasan yang masih terjadi kepada wartawan hingga data indeks demokrasi dan kebebasan pers yang mengalami penurunan selama satu dekade terakhir yang mencapai 6,3 pada 2020 menjadi salah satu fakta bahwa kebebasan tersebut ternyata masih belum dirasakan oleh para jurnalis, maka dari itu peneliti tertarik meneliti tentang kebebasan pers di era Jokowi. Metode yang digunakan dalam penelitian ini adalah kualitatif deskriptif dengan menggunakan teori fenomenologi Alfred Schutz yang membagi pada tiga aspek penting dalam mengkonstruksi makna dari realitas sosial atau fenomena yang terjadi, yaitu aspek pemahaman, aspek pengalaman, dan aspek pemaknaan. Informan dalam penelitian ini adalah empat Pemimpin Redaksi media massa di Surabaya yang sudah tersertifikasi oleh Dewan Pers. Dari hasil penelitian yang dilakukan bersama keempat informan, persepsi mereka tentang kebebasan pers di era kepemimpinan Presiden Jokowi yang mereka rasakan adalah Jokowi dalam memperlakukan media-media yang kritis tidak lagi dengan cara-cara yang koersif, dengan kekuasaan, dengan ancaman ataupun dengan tekanan politik seperti era-era sebelumnya tapi dengan memanfaatkan bisnis media di era ini yang pengendalinya market sebagai salah satu cara yang dilakukan pemerintah untuk melemahkan media yang kritis terhadap pemerintah yaitu dengan terbatasnya akses-akses ekonomi yang akan mereka dapatkan.

Fucoidan is a sulfate polysaccharide compound that is widespread in the sea, especially in brown algae. Previous fucoidan pharmacokinetics studies have shown that fucoidan nanoparticles have the effect of increasing the immunomodulatory ability of fucoidan, but fucoidan consumed orally has a half-life in plasma of about 3 hours so that to reduce the amount of fucoidan supplement use in a day, fucoidan can be formulated into sustained release tablet preparations. The purpose of this study was to determine the optimal composition of Na. Alginate and HPMC as polymers in sustained-release tablet preparations containing purified fucoidan from brown seaweed to produce tablets with characteristics that meet the compendial requirements of the Indonesian Pharmacopoeia and can maintain fucoidan release in plasma with only one consumption per day to improve user compliance. Fucoidan extraction from brown seaweed was carried out using hot extraction. Purified fucoidan tablets were prepared by the Simplex Lattice Design method using Design Expert version 10.1. The concentration of Na. Alginate and HPMC used as much as 2–5% with 8 formulas, which were then printed on a tablet printing tool. The optimum formula was tested as an immunomodulator in mice with parameters for lymph weight, phagocytosis index, and stimulant index. Optimum formula for Na. alginate: HPMC (3.252:3.748%) with flow speed 8.552 g/sec, compressibility 15,648%, hardness 3.726 kg, friability 0.044%, MC 3.296, Crushing time 21.34 minutes, Q15 34.608%, Q45 34.824%. The optimum formula for the immunomodulatory effect had a significant effect on the lymph weight of mice.

O estresse laboral pode desencadear uma série de consequências prejudiciais, afetando diretamente a saúde dos profissionais e a qualidade dos serviços que prestam. Os sintomas resultantes desse estresse crônico podem culminar na síndrome de burnout (SB), um estado debilitante caracterizado por esgotamento emocional, despersonalização e falta de realização no trabalho, frequentemente provocado por jornadas prolongadas. Entre os diversos ramos de atividade, profissões de saúde estão entre as que mais estão associadas a doenças ocupacionais, com a SB sendo notadamente reconhecida. Este estudo tem como objetivo caracterizar os aspectos gerais da SB, com foco nas profissões do campo da saúde, examinando os impactos na vida cotidiana dos indivíduos afetados. Dada a alta proporção de profissionais afastados devido ao aumento da exaustão física e psíquica, é essencial que pesquisas futuras se concentrem em desenvolver estratégias para melhorar as condições de trabalho dos profissionais de saúde, buscando abordagens que promovam uma melhor saúde ocupacional para esses profissionais, o que, por sua vez, se refletirá em um impacto positivo em sua qualidade de vida e resultará em uma melhoria na qualidade dos serviços prestados.

A menopausa é uma fase de transição significativa para as mulheres, frequentemente associada a sintomas como depressão, insônia e deterioração da saúde física e mental, o que compromete a qualidade de vida e o bem-estar geral. Estratégias não-hormonais, como intervenções psicossociais e exercícios físicos, podem melhorar a qualidade de vida e o manejo da saúde mental e da depressão em mulheres na menopausa e pós-menopausa.Este estudo teve como objetivo avaliar, por meio de uma revisão sistemática, a eficácia dessas intervenções e sua influência na autopercepção das mulheres no contexto social. Foram analisados seis artigos selecionados das bases de dados PubMed Central, Scielo e LILACS de acordo com buscas dos termos "Menopause" e "Postmenopause" combinados com "Quality of Life" e "Mental Health", após esta triagem foi realizada a exclusão de publicações relacionadas a "Hormonal", "drug therapy" e "hormone". Os resultados destacaram a eficácia dos exercícios, incluindo aeróbicos, resistidos, aquáticos e práticas como ioga, na melhoria dos sintomas não fisiológicos (mentais e emocionais) em mulheres na menopausa. As intervenções não hormonais, mostraram-se seguras e eficazes para melhorar a saúde psicológica e a qualidade de vida. A continuidade dessas práticas é crucial para alcançar resultados duradouros, embora sua eficácia varie conforme as características individuais. Pesquisas futuras são necessárias para otimizar essas metodologias e maximizar seus benefícios.
EDUCAÇÃO ANTIRRACISTA NA BAHIA: UMA REFLEXÃO A PARTIR DA LEI 10.639/2003

Published: October 2024

O Brasil possui a segunda maior população negra do mundo, sendo a Bahia o estado com a maior proporção de pessoas que se identificam como negras. A partir disso, o estado da Bahia, através de uma política de educação antirracista nas escolas, torna obrigatório o ensino da História e Cultura Afro-Brasileira e Indígena. Assim, este artigo objetiva analisar as produções acadêmicas, relacionadas à educação antirracista, com foco na implementação da Lei nº 10.639/2003, desenvolvidas em programas de pós-graduação stricto sensu na Bahia. A pesquisa analisou teses e dissertações produzidas entre os anos de 2019 e 2024 em universidades baianas, revelando avanços e desafios na aplicação dessas políticas. Apesar de progressos representativos, como a inclusão de temas étnico-raciais nos currículos, persistem dificuldades, como a falta de formação continuada para educadores e a resistência a mudanças. O estudo destaca a importância de uma abordagem integrada e contínua para enfrentar o racismo estrutural e promover uma educação inclusiva, evidenciando a necessidade de estratégias pedagógicas inovadoras e o envolvimento ativo das comunidades escolares.
UM OLHAR CIENTÍFICO PARA O BIOCAMPO HUMANO: PESQUISAS RECENTES, AVANÇOS, LIMITAÇÕES TECNOLÓGICAS E DESDOBRAMENTOS NA ÁREA DA SAÚDE
Authors: Santos Elias

O biocampo humano ainda é um assunto pouco explorado na comunidade científica mundial por várias razões limitantes, incluindo a sua complexidade. Atualmente, a ciência do biocampo é considerada uma área emergente de estudos, que busca prover uma fundamentação científica para entender a regulação homeodinâmica dos sistemas vivos. Estudos recentes têm apresentado avanços significativos no entendimento do biocampo e o assunto vem recebendo cada vez mais atenção e aceitação da comunidade científica. Neste sentido, o objetivo do presente capítulo é apresentar um panorama atualizado desse assunto em uma linguagem didática e acessível para uma grande audiência, proporcionando maior conhecimento sobre o tema e promovendo a sua divulgação científica. Por exemplo, estudos recentes têm mostrado que o corpo humano emite fótons e possui um campo magnético que se estende além do corpo físico. Esses fenômenos podem estar relacionados a mecanismos de comunicação entre o corpo físico e o seu biocampo, mas que ainda não há comprovação científica. Além disso, este processo de comunicação vem sendo abordado por alguns autores como um exemplo de entrelaçamento quântico, e que o mesmo desempenha um papel importante na regulação e saúde do organismo vivo. Em terapias energéticas e medicina integrativa é entendido que a comunicação entre o biocampo e o corpo físico pode ser intermediada pelo terapeuta, resultando em equilíbrio, bem-estar e contribuição para a cura do paciente. O biocampo humano é um sistema complexo e a sua ciência ainda está na infância. A sua compreensão vai além do conhecimento científico contemporâneo e mais investigações são necessárias para o progresso da ciência do biocampo, o que trará grandes contribuições para diversas áreas, principalmente a da saúde.
