Simple synthesis of floating Fe2O3/Luffa catalysts for the photo-Fenton degradation of methyl orange at near neutral pH
Authors: Quynh Nhu Le Thi , Thi Quynh Trang Ly , Anh Tien Nguyen , Quoc Thiet Nguyen , De-Hao Tsai , Tien Khoa Le
Published: June 2024

Although widely used in the textile industry, methyl orange is considered one of the most toxic dyes, which have negative impacts on the aquatic environment and needs to be removed from water bodies. Hence, the present paper reports the synthesis of new floating photo-Fenton catalysts based on the immobilization of Fe2O3 nanoparticles on the surface of Luffa sponges for the oxalate-induced-degradation of methyl orange. The floating catalytic sponges were prepared through a simple precipitation method followed by a reflux heating process and then characterized by field emission scanning electron microscopy, X-ray diffraction, atomic absorption spectrometry, and nitrogen adsorption-desorption experiments. According to the experimental results, methyl orange was effectively degraded over our floating catalytic sponges underlight illumination at near neutral pH. The catalytic activity was also found to be enhanced with the increase in crystallinity of Fe2O3 nanoparticles, which can be achieved by the reflux heating. Besides, owing to the floating feature, these sponges are easily separated from the solution, thereby not forming a secondary source of pollution for water

Protocols for assembly of a serine integrase-based platform for functional validation of genetic switch controllers in eukaryotic cells v1
Authors: A. de Oliveira Marco
Published: June 2024

This is a collection of protocols for assembly of a serine integrase-based platform for functional validation of genetic switch controllers in eukaryotic cells in human, animal and plants. Serine integrases (Ints) are a family of site-specific recombinases (SSRs) encoded by some bacteriophages to integrate their genetic material into the genome of a host. Their ability to rearrange DNA sequences in different ways including inversion, excision, or insertion with no help from endogenous molecular machinery, confers important biotechnological value as genetic editing tools with high host plasticity. Despite advances in their use in prokaryotic cells, only a few Ints are currently used as gene editors in eukaryotes, partly due to the functional loss and cytotoxicity presented by some candidates in more complex organisms. To help expand the number of Ints available for the assembly of more complex multifunctional circuits in eukaryotic cells, this protocol describes a platform for the assembly and functional screening of serine-integrase-based genetic switches designed to control gene expression by directional inversions of DNA sequence orientation. The system consists of two sets of plasmids, an effector module and a reporter module, both sets assembled with regulatory components (as promoter and terminator regions) appropriate for expression in mammals, including humans, and plants. The complete method involves plasmid design, DNA delivery, testing and both molecular and phenotypical assessment of results. This platform presents a suitable workflow for the identification and functional validation of new tools for the genetic regulation and reprogramming of organisms with importance in different fields, from medical applications to crop enhancement, as shown by the initial results obtained. This protocol can be completed in 4 weeks for mammalian cells or up to 8 weeks for plant cells, considering cell culture or plant growth time.

Authors: Amaya Avalon , Swapp Jackie
Published: June 2024

This protocol describes a semi-customized workflow to perform water restriction with mice designated for future experiments. Water restriction is a common method used to increase engagement and motivation of mice performing behavioral experiments that use water as a reward. Water restriction timeline summary: Mice should have three daily weights collected, which are averaged to determine their baseline weight. The target weight will be a percentage (desired) of their baseline weight. The first day of water restriction begins on the last day of the mouses weight collection and is given 1.0mL of water. The mouse should be weighed and provided at least 1.0mL of water daily while under water restriction. All calculations should be individually determined for each mouse. Mice under water restriction should be closely monitored for health concerns due to the effects of dehydration. All mice should receive 1.0mL of water daily. Follow IACUC and veterinary requirements for water restricting mice.
A Deep Dive into Self-Regulated Learning: Reflective Diaries Role and Implementation Strategies
Authors:   Karlstad University, Ahmad Muhammad O.
Published: June 2024

Reflective learning diaries can help students develop self-regulated learning (SRL), a critical skill for success. For teachers such learning diaries can be a valuable tool for formative evaluation of SRL. However, there is limited research on the use of reflective diaries in software engineering and information systems education. To address this gap, we conducted a case study in which reflective learning diaries were used in a course. The goal of this research is to investigate the potential of using reflective diaries to formatively evaluate three key features of SRL: conceptions of knowledge, conceptions of learning, and strategies for monitoring and regulating learning. Our findings suggest that reflective diaries are a valuable tool for formative evaluation of SRL in software engineering education. Reflection on learning experiences helps students develop self-awareness of their SRL skills and identify areas for improvement. Instructors can use this information to provide students with targeted feedback and support. By using reflective diaries to promote dialogic feedback, instructors can help students to develop a deeper understanding of their learning and become more effective self-regulated learners. The study concludes with lessons learned that provide practical recommendations for educators who are swiftly moving toward online teaching.

The article analyzes the impact of new emerging relationships in financial markets across the world through analysis of new financial operations principles that emerged from such relationship. These principles include the further encouraging of the automation of financial transaction, supporting democratization of finance, self-governance of cryptocurrency exchanges and financial market participants. Such new features of financial market had irrevocably led to appearing of new issues, problems and challenges for law and financial market policymakers. Through analyzing deeply these features by comparing different legal ways to approach it, the possible solutions could be found. However, in no way such solution will be peculiar to only one country. As article demonstrates, all these principles are cross jurisdictional and govern the problems not for one country within its border, but for the essence of it itself that is without border and often without any physical realization. Herein the idea that takes place in these principles such as absence on intermediary, less bureaucracy and capital market not only for professionals should be regulated properly. Thus, the way to it is yet to be found, however understanding the essence of these new principles for financial market operations will help to found effective approach. Moreover, such effective approach may be based on FinTech, RegTech or SupTech that are also analyzed in this article.
CONCEPTUALIZATION OF RISK MANAGEMENT IN THE CORPORATE GOVERNANCE SYSTEM OF MULTINATIONAL ENTERPRISES
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Rushkovskyi M.
Published: June 2024

The purpose of the article is to summarize and present the fundamental trends of the last decade related to the formation of the role and place of risk management in the system of corporate governance of multinational enterprises (MNEs). The analysis is based on the latest research by leading international researchers, such as American scientists Warren Bennis, Bert Nanus, Hugh Grove and Lorenzo Patelli, British scientists Mingzhui Wang, Elizabeth Kelan and Kevin Crowley, international organizations Basel Committee on Banking Supervision, Group of Thirty, Institute of international finance and the Organization for Economic Cooperation and Development. The conducted analysis clearly indicates that failures in MNEs risk management over many years led to catastrophic losses in various industries, when such failures, as in the energy sector, led not only to financial, but also to significant environmental consequences. Among the most significant incidents, we can highlight the accidents on the oil platform "Deepwater Horizon" of the British oil and gas company BP in 2010 in the Gulf of Mexico and the Japanese nuclear power plant Fukushima-1 in 2011. Often these failures also contributed to failures in corporate governance, where boards of directors did not fully consider the risks that MNEs were taking and/or imperfect risk management systems. Thus, the conceptualization of risk management in the system of corporate governance of MNEs becomes an important component of achieving medium and long-term strategic goals of MNEs in conditions of growing macroeconomic and geopolitical uncertainty.

Authors: Gökçe Muhammet Mustafa , Duman Erkan
Published: June 2024

In today's world, where economic and industrial development continues, the importance of electrical energy is constantly increasing. Energy demand should be forecast as precisely as possible to reduce lost energy costs in the system, to plan generation expenditures appropriately, to ensure that market players are not economically harmed, and to deliver quality and uninterrupted energy to system consumers. Balancing the electric energy supply and demand of the system is possible with a forecasting plan. Our research aims to generate hourly electricity consumption load forecasts for the period 2018-2021 using Turkish Electricity Consumption Data and meteorological data, with the addition of time and public holiday features. The forecasting performance of the models is evaluated by training multiple machine learning models and deep neural network-based time series models with the data. When the prediction results of our load demand forecasting problem were evaluated, it was seen that deep learning methods gave higher results in prediction success compared to machine learning models. It has been observed that the prediction success of the LSTM model, one of the deep learning methods we use, is higher than the RNN and GRU models. The analysis envisages the elimination of mismatches between energy supply and demand.

Enerji ihtiyacı insanlığın teknolojik ürünleri kullanması ve gelişimine yönelmesiyle günümüze kadar artarak devam etmiştir. Bu enerji talebindeki artış hatlardan iletilen güç miktarında da artışa neden olmuştur. Bu güç artışı iletim ve dağıtım hatlarına olumsuz bir etki olarak yansımıştır. Bu artışı telafi etmek için üretim artmakla kalmayıp aynı zamanda iletim hatlarının da bu enerji akışı için kordine edilmesi gerekmektedir. İletim hatlarında düzenleme yapılmadığı taktirde artan enerji ihtiyacına karşılık iletilen enerji yeterli gelmeyecek, hatlarda gerilim düşümü ve kayıplar ciddi derecede artacaktır. İletim hatlarından aktarılan güç her zaman sabit değildir, belirli zamanlarda düşüş veya artış göstermektedir. Bu düşüş veya artış iletim sistemi endüktansında ve kapasitesinde farklılıkar meydana getirir. Düşük yük durumlarında kapasitif etkiler meydana gelmektedir ve bunun sonucunda hattan akan kapasitif akım değerinde artış olmaktadır. Bu artış reaktif güç üretimini de beraberinde getirmektedir. Üretilen reaktif gücün tüketilmesi ve hattan iletilen akımın büyüklüğünün azaltılması gerekmektedir. Bu sorunun çözümü için birden fazla yöntem mevcut olmasına rağmen ayarlanabilir reaktif güç kapasitesiyle manyetik kontrollü reaktör en uygun çözümlerden biridir. Manyetik kontrollü şönt reaktörler son yıllarda yaygınlaşan, güç elektroniği ve transformatör sektörünün birleşmesiyle ortaya çıkan efektif bir üründür. Yapılan bu çalışmada, teorik olarak tasarlanan manyetik kontrollü şönt reaktörün elektromanyetik analizleri yapılmış, ürün üretilmiş ve sonuçlar tartışılmıştır.

Society through the prism of constitutional legislation Russia and China
Authors: Komarova V. V.
Published: June 2024

In the article, the author proceeds from the premise that the dynamics of the modern world is reflected in constitutional regulation. At the same time, one of the modern trends in the development of constitutional legislation is the institutionalization of society. The author has shown that the system of universal values, their balance, is the constitutional basis for both a manageable future and for the sustainable development of society and the state. Challenges and threats pose global challenges that States often cannot adequately solve — it requires the consolidation of forces and capabilities not only of the states themselves, but of forces within the state: individual and collective subjects of civil society, the implementation of constitutionally established goals and objectives.
Current trends in the development of legislation on foreign investment in strategic sectors of the economy
Authors: Milchakova O. V.
Published: June 2024

The article deals with some topical issues of the evolutionary development of legal norms on foreign investment in sectors of the economy that are strategically important for the state. It is noted that for 15 years since its formation, the legislation in this area has been intensively improved and in the process of its development, despite some point adjustments to ease administrative regulation, it is generally characterized by increased control of foreign participation in the strategic sectors of the Russian economy. At the same time, the number of areas of economic activity in which foreign investments are subject to state control, the circle of persons subject to restrictive measures for investing in strategic sectors of the economy, as well as the types of transactions of foreign investors subject to mandatory prior notification by state authorities have been increased. These trends are predetermined by the national priorities of the state at a certain stage, the need to ensure economic sovereignty and prevent threats to the country’s defense and (or) state security in the face of international political and economic instability.
The Limitation and Outlet of «Notice-and-Takedown» Rule Applied in New Network Service
Authors: Wang Ya-Peng
Published: June 2024

With the rapid development of Internet technology and business model innovation, new network services such as the small program platform and cloud server in our country develop rapidly. However, there are many problems in the judicial practice of the platform that violates the «Notice-and-Takedown» obligation in the new network service. The correct understanding and flexible application of the «Notice-and-Takedown» rule is the necessary meaning of the new online service platform trading services in accordance with the Tort Liability Law of the People’s. In order to balance the interests between Internet service providers and right holders, the legal positioning of «Notice-and-Takedown» rule should be clearly defined in the application of law, so as to correctly apply it as an exemption clause.

At the same time, when Internet infringement cases occur, the «necessary measures» that Internet service providers should take should be properly determined according to the specific circumstances. Specifically, the application of the «Notice-and-Takedown» rule to the new network service can be solved by clarifying the disclaimer attribute of the «Notice-and-Takedown» rule, taking the «transfer notice» as an implementable necessary measure and requiring the new network service provider to disclose the information of specific developers when necessary.

BACKGROUND: When creating models utilizing artificial neural networks, the quantity of training data and the distribution of data need to be considered, particularly when making gender predictions.
AIM: This study seeks to determine the potential impact of using the synthetic minority oversampling technique (SMOTE) on gender prediction using the artificial neural networks model.
MATERIALS AND METHODS: The current study utilized a dataset consisting of 297 cephalometric measurements from Indonesian patients, comprising 229 samples from females and 68 samples from males. WebCeph is used to measure certain parameters, such as Sella-Nation-Point A (SNA) angle, mandibular length, mandibular angle, Sella-Glabella-Point A (SGA) angle, and diagnosis. Data processing and artificial neural networks model creation were conducted using Python.
RESULTS: The gender identification accuracy of the artificial neural networks model is 87% for females and 0% for males, resulting in an overall average accuracy of 78%. When using SMOTE, the accuracy is 22%, with 0% for females and 37% for males. However, when using SMOTE and normalization, the accuracy increases to 71%, with 82% for females and 30% for males. The accuracy of normalization without SMOTE is 76%, with 86% for females and 14% for males.
CONCLUSIONS: This research has proven the efficacy of SMOTE in improving the classification of male matrices. Nevertheless, this study reveals that the overall accuracy results of SMOTE are suboptimal in comparison to the absence of SMOTE and normalization. The application of data balancing strategies is necessary to achieve optimal accuracy in gender prediction when artificial neural networks, and other parameters must be applied.

Psychosocial stress and its consequences among modern university students: the megalopolis factor
Authors: Rozanov V. A. , Laskaja D. A. , Radionov D. S. , Ruzhenkova V. V.
Published: June 2024

BACKGROUND: Students, who comprise a significant proportion of society, are a vulnerable group that often experiences high levels of stress, affecting their psychological well-being. At the same time, students’ stress has to be assessed comprehensively, taking into account various factors such as living conditions and academic demands, AIM: To assess the psychosocial stress and psychological well-being of students, taking into account the characteristics of the university and the urban environment, whether it is a megalopolis or a regional center. MATERIAL AND METHODS: A cross-sectional study was conducted among students from St. Petersburg State University (SPbSU) and Belgorod State University (BSU) using an online survey method with a snowball sampling technology. The survey questionnaire aimed to gather both qualitative and quantitative data on key stressors, indicators of psychosocial maladaptation and mental health issues using the DASS-21 scale. The collected data was analyzed using IBM SPSS Statistics v. 27. RESULTS: Students at SPbSU exhibited more pronounced signs of psychological distress, such as anxiety, stress, depression, loneliness, fatigue, and a need for psychological assistance. They also, reported facing challenges in in their daily lives, including issues with nutrition and transportation. Additionally, they were more likely to use nonproductive coping mechanisms, such as excessive use of social media and engaging in addictive behaviors. On the other hand, the students at BSU demonstrated a closer and more trusting relationship with their parents, as well as and higher level of financial dependence on their families. However, as for main indicators of academic stress, particularly in relation to the use of online technologies during the pandemic, there were no significant differences between the students of both universities. CONCLUSION: The influence of living in a megalopolis is likely to be the primary factor contributing to the observed disparities in psychosocial maladaptation among the surveyed student populations. More attention should be paid to the adaptation of students to life in large cities, with a focus on support from families and university administrations.

Published: June 2024

BACKGROUND: About a half a century ago, the concept of physiological regeneration of bone tissue was introduced, which is based on the functioning of basic multicellular units (BMUs). Later, such an approach can also be used to understand the regularities of reparative regeneration. Bone grafting using gene-activated synthetic replacement materials introduces additional features into the reparative process because the material becomes an active participant in the process. Bone grafts sequentially undergo resorption and metabolism and become a matrix on the basis of which the BMUs implement regenerative osteogenesis.
AIM: To reveal the function of BMUs in a human bone wound during implantation of a gene-activated osteoplastic material from octacalcium phosphate.
MATERIALS AND METHODS: Microfocal computed tomography, histological and immunohistochemical studies, histomorphometry were analyzed and processed statistically.
RESULTS: When using an ordinary product and a gene-activated material based on octacalcium phosphate, the bone regenerate was represented by a multi-tissue structure formed by bone beams surrounding non-resorbed fragments of bone replacement products. In the histomorphometric analysis of gene-activated material, the median area of the unresorbed granules was 0.039 [0.013; 0.079] mm2, and the median area of the osteoclasts was 67 [22; 235] cells/mm2. In the group using an ordinary product, the values were 0.029 [0.009; 0.068] mm2 and 15 [0; 79] cells/mm2, respectively.
CONCLUSION: BMUs that are in various phases of functional activity (resorption, reversion, formation, and rest) can be detected at the gene-activated material–bone interface. The last phase appears only in cases when the components of the material do not induce osteogenesis.
Are The Beatles Different? A Computerized Psychological Analysis of Their Music
Authors: North Adrian C. , Krause Amanda E.
Published: June 2024

There has been little quantitative research by psychologists concerning the music of The Beatles. The present research compared their music against a database of 169,909 songs for which data was obtained via the Spotify application programming interface concerning acousticness, danceability, duration, energy, key, loudness, mode, popularity, tempo, and valence. The Beatles' music differed from the overall dataset by being more positively-valenced, more energetic, faster, louder, less acoustic, and shorter; and differed from their 1960s contemporaries by being more danceable, energetic, faster, louder, less acoustic, and shorter. Of these, only the loudness and valence of The Beatles' music was related positively to its popularity. The Beatles were able to avoid the overall trend for distinctive music to be less commercially successful, suggesting that they were able to innovate without sacrificing popularity. However, on further analysis, The Beatles' music was no more innovative (defined in terms of musical differences from other music) than that of their contemporaries for each year of the 1960s except 1969. The ongoing public acclaim of The Beatles can therefore be attributed to their music being louder and more emotionally positive, being no more musically-innovative than their peers, but when they did innovate, being relatively successful compared to their peers.
Melodic Pattern Repetition and Efficient Encoding: A Corpus Study
Authors: Temperley David
Published: June 2024

Melodies are full of repeated patterns of pitch, interval, and rhythm. It has been suggested that these repeated patterns aid the listener in creating an efficient encoding; this raises the possibility that compositional practice might have evolved to facilitate this process. I propose three specific hypotheses about compositional practice: 1) Repeated intervallic patterns tend to be metrically parallel, with each instance of the pattern falling at the same position in relation to the metrical structure; 2) Purely intervallic repetitions tend to be confined to short distances (longer-distance repetitions tend to involve repetition of scale-degrees as well); 3) Repeated intervallic patterns tend to involve multiple intervals rather than single ones. In each case, I explain how such a compositional strategy might facilitate efficient encoding. Corpus analyses of classical themes and European folk songs find support for all three hypotheses.
Are The Beatles Really Different? Commentary on North and Krause (2023)
Authors: Condit-Schultz Nathaniel
Published: June 2024

This article is a commentary on "Are The Beatles Different? A Computerized Psychological Analysis of Their Music," by North and Krause (2023), in which they analyze features extracted from the Spotify API and ultimately claim that The Beatles' music is statistically "innovative" compared to other music. In this commentary, I explore potential methodological issues with some of their analyses. Chiefly, I show that applying their analysis to other artists results in similar results in most cases. I conclude that The Beatles' innovativeness, whether real or imaginary, cannot be statistically determined from Spotify's acoustically derived features.

Currently, users of Biacore SPR biosensors (�Cytiva�, USA) are faced with sanctions restrictions on the purchase of consumables (primarily optical chips) for this type of equipments. In this regard, the use of commercially available analogues of the optical chips has become relevant. In this work, a comparative study of molecular interactions was performed on a Biacore X100 SPR biosensor using an original Biacore CM5 optical chip (�Cytiva�, USA) and its analogue CMD500M (�XanTec bioanalytics GmbH�, Germany). Protein A was immobilized on both chips as a molecular ligand, often used in scientific research and biotechnological works to immobilize antibodies on various carriers (biosensor chips, sorbents, nano- and microparticles). An IgG antibody was used as a protein analyte. A comparative study of the interaction of various concentrations of antibodies with protein A immobilized on two versions of the chips was carried out. The values of the kinetic rate constants for the association (kon) and dissociation (koff) of complexes, as well as the equilibrium dissociation constant (Kd), were calculated from the obtained sensorgrams using the interaction model 1:1 (Langmuir) binding. The results of comparative measurements showed similar values of the rate constants and interaction affinities. The differences between the values of kon, koff and Kd were 18%, 10% and 9%, respectively. Thus, this study confirmed the interchangeability of the original SPR chips CM5 and their analogues CMD500M.

Authors: Kusuma Wijaya , Andriatno Ardi , Seno Budhi Hami
Published: June 2024

Background: Lung cancer patients are at high risk for depression, which is associated with poor treatment adherence. Medical hypnosis can improve symptoms of depression and affect interleukin-6 levels. This study aims to determine the effectiveness of medical hypnosis in improving depression and reducing IL-6 levels in lung cancer patients.
Methods: This study is a quasi-experimental study with a pretest and post-test control group design. It assessed depressive symptoms using BDI-II scores and serum IL-6 levels in an intervention group receiving medical hypnosis and standard therapy compared to a control group receiving standard therapy. Data analysis was conducted using univariate tests, followed by Pearson correlation tests and effect size measurement with Cohen's d test.
Results: The Wilcoxon test showed a decrease in IL-6 levels in the intervention group by 14.66±19.45 (p=0.008) and a reduction in BDI-II scores by 8.26±4.78 (p=0.001). Correlation tests indicated a significant relationship between IL-6 levels and BDI-II scores (r=0.472; p=0.009). Cohen's d test showed the effect size of medical hypnosis on IL-6 levels was 0.754 (moderate=0.5<ES<0.8).
Conclusions: Medical hypnosis is effective in improving depressive symptoms and reducing IL-6 levels in lung cancer patients.

La ecología dinámica del hábito alimentario de alevines de bocachico (Prochilodus magdalenae) en condiciones controladas
Authors: Takatsuka Masashi
Published: June 2024

Diversas investigaciones han aportado conocimientos biológicos y ecológicos sobre el bocachico (Prochilodus magdalenae). Aunque se pensaba que el bocachico no aceptaría alimento concentrado debido a sus hábitos alimentarios naturales, se demostró que ingería alimento concentrado en forma de tortas húmedas. Por otro lado, la curva de crecimiento de las postlarvas puede considerarse un modelo de referencia para el manejo adaptado a cada etapa en un programa de producción, pues los resultados de las pruebas con el método de bootstrap han evidenciado una distribución normal, lo que indica que las condiciones de cría, entre ellas, la calidad y la cantidad de alimento, así como otros factores, han sido apropiadas. También se observó que las postlarvas cambiaban sus hábitos alimentarios, pasando del consumo de zooplancton al de organismos presentes en el bentos, y que cuando no había presas en el fondo del estanque de cría, migraban hacia la superficie y allí adoptaban el comportamiento de alimentación llamado “boqueo”; en ese momento las postlarvas tomaban la torta húmeda y se dirigían al fondo para consumirla. Este modelo de hábito alimentario puede considerarse similar al que ocurre en la naturaleza, cuando, después de alimentarse de zooplancton, los bocachicos se dirigen al fondo y se alimentan de flóculos de materia orgánica y fitoplancton. Este es un hallazgo importante para el desarrollo de técnicas de acuicultura sostenible de la especie. Por otra parte, durante el período de alimentación con zooplancton, las postlarvas toman selectivamente cladóceros, principalmente Moina micrura, debido a su tamaño y gran capacidad reproductiva; esta especie, además, sufre una descomposición física al pasar por la faringe y el tracto digestivo y su fluido protoplasmático se absorbe directamente en forma de nutrientes, lo que es una característica crucial de alimento vivo ideal para las postlarvas. Se encontró, igualmente, que cuando la cantidad y calidad del zooplancton, particularmente de M. micrura, son altas durante la etapa de postlarva, los individuos tienen un crecimiento saludable y rápido. Por último, el estudio del índice intestinal relativo y del contenido digestivo sugiere que el cambio en los hábitos alimentarios comienza cuando las postlarvas alcanzan una longitud de aproximadamente 18 mm y adquieren una capacidad digestiva similar a la de los peces de tallas entre 25 y 30 mm.

Este trabalho apresenta um estudo energético e exergético detalhado de um sistema de refrigeração por absorção de vapor de duplo efeito em série com disposição em torre. Esse sistema, que emprega água e brometo de lítio como fluidos de trabalho, usa como fonte de energia térmica para acionar o gerador de vapor, a queima direta do gás natural, e tem como propósito principal a produção de água gelada para um sistema de climatização. Desenvolvido e refinado no Laboratório de Energia Sustentável do Instituto de Energia Sustentável da Universidade Federal da Paraíba, este estudo serve como um suporte valioso e um parâmetro crucial para a otimização do protótipo do sistema. No âmbito da análise termodinâmica realizada, são examinados aspectos energéticos e exergéticos para avaliar tanto quantitativa quanto qualitativamente as irreversibilidades e eficiências dos componentes do sistema em estudo. Utilizou-se o software Engineering Equation Solver para resolver as interações no processo de modelamento matemático dos processos analisados. O chiller de absorção em análise é composto por dois geradores de vapor, um sistema de condensação, evaporador, absorvedor, válvulas de expansão, bomba de solução e um trocador de calor. Os resultados da análise exergética revelam que, em termos de eficiência de segunda lei (racional), o evaporador destaca-se como o componente mais eficiente, registrando uma eficiência de 76,14%, seguido pelo gerador de vapor 1 e o trocador de calor, com eficiências de 53,31% e 51,96%, respectivamente. Em relação às irreversibilidades, o gerador de vapor I e II apresentaram, respectivamente, 58,93% e 22,59% do total das irreversibilidades do sistema. O coeficiente de desempenho do sistema ficou em 1,183.

This descriptive research was conducted with a qualitative approach. The study included three MSMEs of convection in Kudus because Muslimah clothing convection in Kudus is increasing. However, in the production process, several defective products are still found. The existence of these defects indicates the presence of waste in the production process. Therefore, the purpose of this research was to find out the causes of defects in the production process and take corrective steps to reduce defects. Based on the waste identification that has been done, the most critical waste defects are selected using the AHP questionnaire. Then the DPMO calculation was carried out, which showed the sigma level value for the three MSMEs, namely 3.75, 3.57, and 3.64. Next, the root causes of waste was analyzed using fishbone diagrams and FMEA tables. Recommendations for improvements are given to reduce the occurrence of these root causes. If the recommendations for improvement are implemented, there will be an increase in the sigma level for the three MSMEs, namely 4.02, 4.19, and 3.97.
