Rapid growth and catastrophic destruction events of Planchón Volcano, Southern Andes
Authors: Naranjo José Antonio , Romero Jorge , Contreras Juan Pablo , Orihashi Yuji , Scott Kevin , Haller Miguel , Sumino Hirochika
Published: January 2024

During the Late Pleistocene-to-Holocene, the mafic Planchón volcano (35.2 °S, Southern Andes) experienced two important destructive events: a sector collapse to the west and a multiphase explosive eruption transforming the east summit area. We provide new field and laboratory evidence, including geochemical, geochronologic, and geological-morphological analysis, to reconstruct the evolution, triggering mechanisms, and physical parameters of these events.The lateral collapse (48~ka BP) was mainly predisposed by a tectonically westward-inclined substratum and rapid edifice growth rates (0.3–0.48 km3 ka-1). The resulting Planchón-Teno debris avalanche became valley-confined traveling at c. 260 km h-1 up to 95 km distance and forming an 8.6 ± 1.3 km3 deposit. The resulting 4.1 km wide amphitheater was later destroyed at c. 7 ka BP by the multiphase Valenzuela phreatomagmatic eruptions, forming a c. 2.5 km diameter caldera. The case of the Planchón volcano warns that rapidly growing mafic volcanoes imply a substantial catastrophic hazard increase for the surrounding areas.

ON THE QUESTION OF GENRES RESEARCH IN UKRAINIAN ETHNOORGANOLOGY
Authors:   I. Franko Lviv National University, Acad. Filaret Kolessa Ukrainian Folklore Studies Department, FEDUN Iryna
Published: January 2024

The term “genre”, as well as the name of the scientific discipline “genrology” or “genology” is rather novel, but were promptly incorporated into scientific use in various fields of cultural research. The study of arts’ genera has nevertheless a long history and is comprehensively elaborated in literary criticism. Instead, Ukrainian ethnomusicologists have very few special works devoted to the study of traditional music’s genres. Therefore, some information about its generic-gender relations can be derived from the principles of collections’ systematization or performers’ repertoire characteristics in scientific works. Thus, folk instrumental music compositions are divided by structure, function, performing means, origin, etc. However, all known repertoire grouping in ethnoorganology (single or multi-level), unfortunately, are not devoid of logical contradictions. After all, the artistic genre is a heterogeneous and systemic concept; therefore genre systematization is “doomed” to failure because of the inability to adhere to the elementary logical classification principles (unity of the basis, means and proportions, incompatibility and continuity). So it is no accident that the direction of nihilism emerged in genrology. But there is always a need to streamline the analyzed material, so despite all the imperfections of genre classifications, you have to choose the most optimal ones. One of these is the division of art, known since the ancient Greece times, into epic, lyric and drama. Similar to this triad, the division of music into singing (lyrics), dance and moves (drama) and listening (epic) was formed in the Ukrainian ethnoorganology. Author suggests to apply current division for the Ukrainian folklore as well. Therefore, depending on the research purpose, we can group instrumental compositions into certain parameters for the convenience of manipulating the material, but with the awareness of multiplicity of criteria applied to various formal categories.

Relevance of the study. The relevance of this study is that for the first time in Ukrainian theater studies, a comprehensive analysis of the scenographic decision of “Romeo and Juliet” ballet by V. Shakespeare was performed on the stage of Solomiya Krushelnytska Lviv State Academic Theatre of Opera and Ballet in 2014 and an analysis of its ideological, content and stylistic features. The first and the second editions of stage design by Yevhen Lysyk were mentioned and compared for the ballet «Romeo and Juliet» by V. Shakespeare on stage of I. Franko Lviv State Academic Opera and Ballet Theater (first premiere – 19th of April 1968 and the second – 27th of December 1988). It also analyzed in detail the cross-section of the styles and ideas of the artist in the scenography to the revised edition of the ballet (2014) and deciphered scenographic codes in which the universal, cosmic world view of the master on the universe is recorded. Main objective(s) of the study. The purpose of the study is to analyze, compare and explore the three scenographic decisions and find out their common and distinctive features. Methodology. The following research methods have been used in this scientific work: historical, comparative, and hermeneutical. Through historical and comparative methods, we investigated the common and distinctive features of the scenography. Using the hermeneutic method, we were able to scrupulously analyze the main three scenographic codes laid down by Yevhen Lysyk in the scenography of the ballet «Romeo and Juliet» by V. Shakespeare. Results (how the study was done). Summarizing the above, we can conclude that the handwriting of artist Yevhen Lysyk is philosophical, courageous, modern and innovative. The artist refuses to be an observer and speaks to the viewer using allegory and symbolism. Especially these particularities were emphasized by the reviewers of the scenographer’s work literary critic Maria Vallo and musicologist and researcher in the history of the theater Oksana Palamarchuk. Significance for art. This publication helps to understand the contribution of the national Ukrainian painter Yevhen Lysyk in the field of scenographic art, revealing the artist’s handwriting and his outlook. Results/findings and conclusions. Consequently, the main results and conclusions of the study are the identification of the recurrent scenographic codes of Yevhen Lysyk. This is a conflict of worldviews and the Renaissance and Middle Ages; a stone prison that embodies hostility and strife between two families; faith, reaction to the cataclysms (canvas «Resurrection»); cosmogonic motives: sun, lakes, mountains, sky

The environment for the formation of the identity of the Greek Catholic metropolitan Andrey Sheptytsky
Authors:   Lomonosov Moscow State University, Pshenichnyi Aleksandr
Published: January 2024

The article discusses the origins of the identity of Andrey Sheptytsky (secular name Roman), which have significant scientific relevance for a better understanding of the activities of this notable figure of the Greek Catholic Church in the national and confessional spheres. We will examine the Sheptytsky family, their family traditions, political views, social status, attitude towards religion, the hierarch parents’ national self-awareness, and their surroundings. The essence of the formation of gente Rutheni – natione Poloni, to which the metropolitan’s father belonged, is described. Information is provided about Andrey Sheptytsky’s mother, Zofia, the daughter of the famous Polish playwright A. Fredro. Priority attention is given to the period of Roman Sheptytsky’s secular education, both secondary and higher. The political and religious atmosphere of Krakow is analyzed, including the educational institutions in which the future metropolitan studied. The article reveals the motives for Sheptytsky’s choice of the path of monasticism, focuses on the influence of people whose authority influenced this decision of a young man. The conclusion is drawn that a whole range of factors (the complex national and confessional history of the Sheptytsky family, the presence of carriers of ultramontanism and paternalistic conservatism around the young Sheptytsky, acquainted with the spirit of the era of modernization and able to provide answers to its challenges) influenced the formation of the future metropolitan’s identity and his choice of his life path.
From the background of the Russo-Turkish War of 1877–1878: the Russian-Romanian military Convention and the agreement with the partnership of Greger, Horvitz and Kogan
Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Frolova Marina
Published: January 2024

The article reveals, based on published and archival documents, the reasons the Russian command of the Danube Army on the eve of the Russo-Turkish war of 1877–1878 concluded an agreement for the supply of food and fodder with the partnership of Greger, Horvitz and Kogan. The path of the Russian army to the theater of military operations on the right bank of the Danube passed through the territory of Romania. The draft of Russian-Romanian military convention was drawn up in November 1876, and the convention was signed on April 4 (16), 1877, just before the declaration of war on April 12 (24), 1877. The low capacity of the railways of the Principality prevented timely delivery of food and fodder from Russia. In the absence of a convention, it was impossible to publicly make purchases in Romania, to prepare warehouses officially and in advance. The Ministry of Finance of Russia allocated only credit rubles to cover expenses, and in Romania only hard money was in use. The Commander-in-chief believed that under such circumstances it was possible to arrange the provision of troops abroad only through the medium of private commission agents. The partnership of Greger, Horwitz and Kogan was chosen, since it had considerable capital, offered to supply the entire list of required products, not only its individual items, as indicated in the calls of other commission agents, and received payment in credit rubles, not gold. In addition, its members had a good business reputation.
Proto-Slavic *čerěnъ and *černъ. I. Vault (of the hearth)
Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Saenko Mikhail
Published: January 2024

In etymological literature, one can come across the reconstruction of several homonymous words *černъ and/or *čerěnъ in the Proto-Slavic language. The highest number of reconstructed words is four while the lowest number is two. The reconstructions differ both in form and semantics. This article attempts to determine which position is best supported by facts and to clarify the reconstructed meanings. The analysed material suggests that we should differentiate between *černъ ‘handle’ and *čerěnъ / *čerěnь / *čerenъ / *čerenь (?), which denoted a certain part of the hearth, most likely the vault. It is highly probable that certain designations of nets in West Slavic languages are also continuants of the latter word. Etymologically, *čerěnъ / *čerěnь / *čerenъ / *čerenь is most probably related to the verb *kuriti (sę), although alternative explanations are possible.
“In Line with” and “Against the Current”: Changes in Ideological and Artistic Focus in Dominik Tatarka’s Works
Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Shirokova Liudmila
Published: January 2024

The Slovak writer Dominic Tatarka has been working for more than forty years, and his writings fully reflect the dramatic shifts both in his personal life and that of the country as a whole. Tatarka has written in many genres. He started with existentialist and surrealist novellas (“The gloom of searching”, 1942; “The lady enchantress”, 1944), moving on to a socio-psychological novel (“The parish republic”, 1948), which reflected the author’s own experience during the war. His novels on the formation of the new man were written according to the canons of socialist realism (“The first and second strikes” (1950), “The day of joy” (1954), “The friendship years” (1954)). The 1956 satirical pamphlet “The demon of agreement” clearly showed the author’s political disillusionment. In the “Endless conversations” (1959) and “Wicker chairs” (1963) novellas, Tatarka returned to the examination of complex spiritual issues, reexamining his personal emotional experience. From mid-1960s onwards the writer mostly wrote non-fiction works, focusing on the issues of national identity and culture. After the events of 1968, Tatarka was excluded from public and intellectual life. His later works, “Bad Weather” (1978), “Notes” (1984), “One against the night” (1984), “Letters to eternity” (1988), “Records with Dominic Tatarka” (2000), “Letters to beloved Lutetia” (2013) were written as essays, employing inner monologue, dialogues with imaginary or real characters, reminiscences, political reflections and erotic sensations.

Authors: Bhandari Samir Raj , Chhetri Aasish , Rai Anil , Rawal Madan , Deub Rabin
Published: January 2024

Solar energy has been one of the most promising energy sources since the 1990s. However, the efficiency of solar panels is reduced due to dust accumulation over modules, which blocks the incident light from the sun. The efficiency of a solar panel depends on various factors, such as the quality of the solar cells, the design of the panel, the temperature and intensity of the sunlight, and the presence of any shading or obstructions. High-efficiency solar panels can produce more electricity from the same amount of sunlight, resulting in higher energy production and cost savings over the system’s lifetime. The study used a semi-automatic cleaning mechanism, which is one of the recent developments made on automated cleaning systems of solar photovoltaic modules. Aims of this study is to improve the efficiency of solar panels by designing and implementing a semi-automatic dust-cleaning mechanism. This study found that the experimental model shows improved efficiency by about 7 percent. The study’s findings are consistent with previous research that emphasizes the importance of regular cleaning of solar panels to improve their efficiency and reliability. This research has important implications for improving the efficiency and reliability of solar energy systems. Solar panel owners can improve the profitability and sustainability of their system, leading to more widespread adoption of solar energy by optimizing the cleaning process and reducing maintenance costs.

Authors: Luitel Pramisha , Luitel Nishaka , Thapa Neha , Bajracharya Anup Muni
Published: January 2024

Objectives: To evaluate the antibacterial activities of different honey samples against clinically isolated bacteria and also to compare the antibacterial activity of honey with standard antibiotics
Methods: A study was conducted to evaluate the potent attributes of eight distinct types of honey against five pathogenic bacteria which were collected from Bharatpur Hospital of Chitwan. The susceptibility of isolates to honey was evaluated using the Agar well diffusion method. In addition, the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of the effective honey samples were determined using tube macro-dilution method. MIC represents the lowest concentration at which visible inhibition of bacterial growth occurs, offering insights into the honey’s inhibitory potential. Furthermore, MBC, determined by sub-culturing the non-turbid wells from the MIC assay, elucidates the minimal concentration required for complete bactericidal activity.
Results: Among the eight types of honey processed, Rudilo honey exhibited remarkable effectivity against Escherichia coli and Staphylococcus aureus, with zone of inhibition of 39 mm and 36 mm, respectively. Conversely, Manuka and Chiuri displayed heightened efficacy against Klebsiella pneumoniae with zone of inhibition 34 mm) and Proteus vulgaris (38 mm). Among the tested bacteria, Pseudomonas aeruginosa demonstrated notable resistance to all honey samples except Rudilo, Manuka, and Multiflora. Furthermore, Manuka and Rudilo exhibited the lowest MIC (6.25% v/v) against Proteus vulgaris and Staphylococcus aureus, while Rudilo displayed the lowest MBC (25% v/v) against the same pathogens. However, Chiuri presented the highest MIC and MBC against the tested bacteria. It was found that honey samples showed a greater zone of inhibition than antibiotics used against Escherichia coli, Proteus vulgaris, Klebsiella pneumoniae, and Staphylococcus aureus but for Pseudomonas aeruginosa antibiotics were found to be more effective than sampled honey.
Conclusion: The study revealed that honey exhibited antibacterial properties even at its minimum inhibitory concentration (MIC), showcasing effectiveness against infections caused by Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae and Proteus vulgaris. However, its efficacy in treating infections attributed to Pseudomonas aeruginosa might be limited.

Published: January 2024

Objective: The gut and salivary gland contain diverse micro biota and play an important role in vector competence and disease transmission. In light of this, this study aimed to screen the salivary gland and midgut microbiota associated with Aedes aegypti and Aedes albopictus from Kathmandu and Lalitpur districts of Nepal.
Methods: An analytical cross-sectional study was conducted from April 2017 to October 2017 in Kathmandu and Lalitpur districts of Nepal. The fi eld collected mosquitoes larvae were reared in the laboratory until the adult emergence and identified morphologically using standard key. The dissected salivary gland and gut samples were homogenized, suspended in phosphate buffered saline and inoculated in the culture media for bacterial growth which were further identified.
Results: Pseudomonas aeruginosa was predominant bacteria in the gut and salivary gland of Ae. aegypti. Similarly, in Ae. albopictus, Serratia marcescens was predominant in gut while, Acinetobacter spp. was predominant in salivary gland. Simpsons diversity index (D), Shannon weaver diversity index (H) and Evenness (E) were found to be the highest viz, 0.81, 1.83 and 0.88 in the gut of Ae. aegypti.
Conclusion: This study had provided a comprehensive overview of the bacterial population in the gut and salivary gland of Aedes aegypti and Aedes albopictus. It was found that the most bacterial genera were common to both vectors, although some variation was found in gut and salivary gland. This distribution suggests that there are no host-specific bacterial genera.
Doing Big Things in a Small Way: A Social Media Analytics Approach to Information Diffusion During Crisis Events in Digital Influencer Networks
Authors: Kishore Shohil , Errmann Amy
Published: January 2024

Digital influencers play an essential role in determining information diffusion during crisis events. This paper demonstrates that information diffusion (retweets) on the social media platform Twitter (now X) highly depends on digital influencers’ number of followers and influencers’ location within communication networks. We show (study 1) that there is significantly more information diffusion in regional (vs. national or international) crisis events when tweeted by micro-influencers (vs. meso- and macro-influencers). Further, study 2 demonstrates that this pattern holds when micro-influencers operate in a local location (are located local to the crisis). However, effects become attenuated when micro-influencers are situated in a global location (outside of the locality of the event). We term this effect ‘influencer network compression’ – the smaller in scope a crisis event geography (regional, national, or international) and influencer location (local or global) becomes, the more effective micro-influencers are at diffusing information. This shows that those who possess the most followers (meso- and macro-influencers) are less effective at attracting retweets than micro-influencers situated local to a crisis. As online information diffusion plays a critical role during public crisis events, this paper contributes to both practice and theory by exploring the role of digital influencers and their network geographies in different types of crisis events.

Los genotipos fueron agrupados de acuerdo a su comportamiento relativo en los dos años para un conjunto de 14 variables agronómicas y de calidad física de grano, y analizados por análisis de grupos. Se estudiaron las variables que explicaron en cada caso la separación de grupos. Los testigos mostraron la capacidad de mantener un buen rendimiento y calidad de grano en condiciones climáticas limitantes. En el año de alta producción varios genotipos introducidos superaron a los mejores testigos, pero ninguno mantuvo ese comportamiento superior en condiciones ambientales limitantes. Este comportamiento se asoció a ciclos a espigazón más largos y períodos de llenado de grano más cortos, que dificultan la adaptación a las condiciones nacionales. El uso de germoplasma introducido resultó un camino ineficiente para el logro de altos potenciales de rendimiento que se asocien a niveles altos y estables en calidad de grano.

En el presente trabajo se incluyen datos de cinco ensayos (dos en invierno, dos en primavera y uno en otoño), realizados en el criadero de cerdos de la Facultad de Agronomía (Uruguay), donde se estudiaron tres sistemas de calefacción para lechones. El objetivo fue el de evaluar, térmica y productivamente, los sistemas de calefacción. Se utilizaron 39 cerdas con sus camadas, alojadas en parideras individuales del tipo semiabierto. Los sistemas, combinación de dos fuentes de calefacción una en cada mitad de la lactación (56 días), fueron: S1= lámpara infrarroja y común de 100W con techo, S2= lámpara común de 150W con techo y techo sin fuente, y S3=nido de madera sin fuente. El S1 fue común a todos los ensayos, S2 en los dos primeros y S3 en los restantes. Los datos fueron analizados en tres períodos: inicial (0-28d), final (29-56d) y total (0-56d). Los promedios generales registrados fueron: TM=25.1 ºC; tm=17.9 ºC; GPI=11.7 kg; EC=0.61; lechones destetados 7.33; mortalidad 21.4%; incidencia de diarrea 5.2%; peso al destete: individual 13.2kg, camada 90.4 kg y; consumo total ración 7.22 kg. Se detectaron diferencias significativas para: *) las temperaturas máximas (TM) y mínima (tm) siempre mayores para el S1, menos para la primera mitad en el ensayo II donde S2>S1 (P<.01); *) la ganancia individual (GPI) ensayo II S2>S1 (P=.099) y, ensayo V S3>S1 (P=.083); y *) la eficiencia de conversión (EC) ensayo III S3 mejor que S1 (P=.088). Se puede concluir que es factible sustituir a la lámpara infrarroja por lámparas comunes o nidos de madera, como forma de protección de los lechones contra las bajas temperaturas.

Se estudió la respuesta productiva del tangor “Ellendale”, a diferentes fechas de anillado, bajo las condiciones de cultivo de España y Uruguay. El anillado realizado en caída de pétalos y treinta días después, disminuyó la abscisión de estructuras reproductivas en ambas situaciones. el cuajado final se incrementó en forma significativa con respecto al testigo, elevándose de 1.6% del total de flores formadas, a un máximo de 2.3% en España y de 1.6% a 2.7%en Uruguay. Como consecuencia, los rendimientos se incrementaron en forma significativa en ambas fechas de anillado. En la parcela de España, fechas posteriores de anillado, no mejoraron el comportamiento del testigo. En Uruguay, en el segundo año de estudio, la densidad de floración disminuyó significativamente en los árboles anillados el año anterior, con valores de 55 flores/100 nudos en el testigo y de 24 y 20 flores/100 nudos en ambas fechas, respectivamente. El porcentaje de cuajado aumentó de 5.3% en el testigo, a 7.0% y 11.7% en los dos momentos de anillado, pero no fue suficiente para compensar la menor floración, lo que resultó en una disminución de los rendimientos en el segundo año. Se discuten los resultados en términos de las relaciones floración-fructificación de este híbrido.

ABSTRACT
The Complete Systematic Land Registration Program (PTSL) is one of the initiatives of the Ministry of Agrarian and Spatial Planning/National Land Agency to register land ownership throughout Indonesia. In its execution, the PTSL program still gives rise to various issues, including cluster 3. The emergence of Cluster 3 poses a substantial challenge to the attainment of the PTSL program's objectives. This circumstance is plausible due to cluster 3 (referred to as "K3") being a product of the PTSL, with its implementation phase yet to culminate in the issuance of certificates. The implementation of the PTSL program could encounter impediments arising from the manifestation of the K3 cluster issue. This study aims to scrutinize the resolution strategies pertaining to the K3 clusters at the Semarang City Land Office. Employing a qualitative methodology under a case study framework, the research focuses on the identification of cluster 3 occurrences within the Gajahmungkur and Candisari Districts. Data collection techniques encompass observation, document analysis, and interviews. The findings of this study reveal that several initiatives have been undertaken to address K3 matters, notably K3.1 and K3.3 clusters. The resolution endeavors encompass both administrative and technical measures, entailing the augmentation of rights through compliance with the prerequisites specific to each cluster 3, alongside the deactivation of K3 parcel identity numbers (NIB K3) and the utilization of NIB K3.

INTISARI
Program Pendaftaran Tanah Sistematis Lengkap (PTSL) merupakan salah satu program Kementerian Agraria dan Tata Ruang/Badan Pertanahan Nasional untuk mendaftarkan kepemilikan tanah di seluruh Indonesia. Dalam pelaksanaannya, PTSL masih meninggalkan berbagai permasalahan termasuk masalah klaster 3. Munculnya klaster 3 menjadi masalah serius dalam pencapaian program PTSL. Hal ini dimungkinkan karena K3 adalah produk PTSL yang tahap implementasinya belum mencapai penerbitan sertifikat. Implementasi PTSL akan terhambat oleh munculnya klaster K3. Penelitian ini bertujuan untuk mengkaji penyelesaian klaster K3 di Kantor Pertanahan Kota Semarang. Penelitian ini menggunakan metode kualitatif dengan pendekatan studi kasus. Studi kasus dilakukan pada temuan klaster 3 di Kecamatan Gajahmungkur dan Kecamatan Candisari. Teknik pengumpulan data dilakukan melalui observasi, studi dokumen, dan wawancara. Dari hasil penelitian ini diketahui bahwa telah dilakukan beberapa upaya untuk menyelesaikan lapangan K3, terutama K3.1 dan K3.3. Penyelesaian dilakukan secara administratif dan teknis, yaitu melalui peningkatan hak dengan memenuhi persyaratan masing-masing Klaster 3 dan menonaktifkan Nomor Identifikasi Bidang (NIB K3) serta memanfaatkan NIB K3.

Cheeses are among the most popular dairy products consumed worldwide. Their popularity is explained by excellent taste qualities, the content of proteins of high biological value (having all essential amino acids in their composition in the optimal ratio), easily digestible milk fat and a widely represented assortment. Developed countries of the world consume cheese in the amount of 15-20 kg per capita per year. The cheese-making industry includes both large industrial enterprises with a capacity of up to 800 tons of processed raw material per shift, and small enterprises whose raw material processing volume does not exceed 100 liters per shift. The use of ultrafiltration in the technology of producing solid and semi-solid cheeses is a promising direction in the dairy industry. Semi-permeable membranes allow to separate or concentrate heterogeneous (heterogeneous) mixtures, regulating their composition and properties. This paper provides data on physicochemical and microbiological parameters of milk raw materials during their membrane treatment. With the introduction of membrane methods for the separation of raw materials, the concentration of proteins and fat in the separated phase increases. The identified trend allows us to conclude that it is necessary to use these methods of cheese making more widely.
O NEOLIBERALISMO, A SUPREMACIA DO MERCADO E A CRÍTICA À IDEIA DE JUSTIÇA SOCIAL
Authors: Bedin Gilmar Antonio , Felzke Schonardie Elenise
Published: January 2024

O domínio da agenda política dos países do Ocidente pelas ideias neoliberais está fechando um ciclo de cinquenta anos de história. Em relação a esta hegemonia, pode-se fazer várias perguntas. Uma destas perguntas é qual o conceito de direito e de justiça que esta forma de pensar a organização da sociedade sustenta e busca implementar? O presente trabalho apresenta uma das respostas e o faz a partir da análise da obra de um dos seus mais importantes formuladores teóricos: Friedrich August Von Hayek. Por isso, o artigo destaca quem é o autor e quais são os principais pressupostos de sua obra sobre o tema. O objetivo é demonstrar que o autor formula uma visão muito restrita do direito e da justiça e que, se as mesmas continuarem a ser sustentadas, as rupturas sociais hoje presentes nas sociedades democráticas ocidentais continuarão a se aprofundar. É que o núcleo central de sua proposta tem ajudado a manter a supremacia do mercado como um sistema autorregulado e reduzido a ideia de justiça social apenas a um conceito oco, que ninguém sabe o que significa. O método de pesquisa utilizado foi o hipotético-dedutivo, a técnica de pesquisa usada foi a bibliográfica e a interpretação feita foi a jurídica.

This study aims to isolate cellulolytic bacteria that have the potential to degrade cellulose by taking home-scale diaper waste samples. This research was also conducted to isolate and determine the ability of bacteria to degrade cellulose based on the Congo red test and filter paper degradation test. This research method is descriptive qualitative. Isolation of cellulolytic bacteria was carried out using selective Carboxymethyl Cellulose (CMC) media. The characterization was carried out by growing selected pure isolates on CMC media and then dropping congored drops to test their cellulolytic potential (cellulolytic potential is indicated by the appearance of a clear zone around the colony). The results showed that the results of isolating bacteria obtained 12 isolates that were able to grow and utilize cellulose as a carbon source. In the Congo red test isolate DS07 cellulolytic bacteria of the Hafnia genus had the highest cellulolytic index value of 2.5 mm. Isolate DS03 with the genus Bacillus had the highest ability to degrade cellulose on the Whatman No. filter paper test. 1 of 16.66%.
