Authors: Wang Yin , Zeng Xiaolan , Li Qiao , Jin Jiyuan , Xiao Shuang , Xu Xiaotang , Ding Wenchuan
Published: September 2024

To promote adsorption capacity of biochar as engineering material, pinewood biochar (PC) and bamboo biochar (BC) were prepared by slow pyrolysis (700 °C) and then directly irradiated with UV light at room temperature. The elemental analysis, SEM, FTIR, XPS, and Boehm titration measurements showed that UV irradiation significantly increased the BET surface area, porosity, and surface oxygen functional groups of the biochar. After UV treatment, the BET surface areas of PC and BC were increased by 63.0% and 217%, while the amount of total (acidic) groups increased by 62.0% (155%) and 24.9% (28.2%), respectively. FTIR and XPS measurements suggested that photochemical reactions, including photodegradation and photooxidation processes, may play primary roles in altering biochar the pore structure and surface functional groups of biochar. The Langmuir model capacities (qmax) of modified PC and BC were increased by 94.5% and 50.5% for Pb (II), 18.5% and 13.7% for Cd (II), respectively, compared to their unmodified counterparts. This study examined the effects of UV irradiation on the surface properties of biochar and demonstrate its potential as an effective, simple, and green method for functionalizing biomass material.

Published: September 2024

Finger joints are one of the most important and widely used joints in the wood and wood products industry. The design, type of construction, and the type of glue used, etc., are the most important things in this joint that determine its final quality. In this research, the effect of cellulose nanofiber and nanoclay in polyvinyl acetate (PVA) glue at levels of 0, 0.4, and 1.5% in finger joints with lengths of two fingers of 5 and 10 mm was investigated by the free vibration in free-free beam method. In joints without nanoparticles, finger joints with a finger length of 10 mm had better acoustic properties than joints with a finger length of 5 mm, except for the acoustic conversion efficiency factor. The results showed that by adding cellulose nanofiber (CNF) and nanoclay in both finger lengths of 5 and 10 mm at both 0.4% and 1.5% levels, the dynamic modulus of elasticity, elastic stiffness, acoustic coefficient, and acoustic conversion efficiency increased significantly, while the damping factor values showed a significant decrease. In general, the effect of CNF on the acoustic properties of both types of joints was better than that of nanoclay.

En este trabajo de investigación, se analizó un mineral de la zona de Yarusyacán, cuya mineralogía reveló la presencia de esfalerita tipo 2 con una granulometría de 35 a 150 micras, además de especies como cuarzo, pirita, pirrotita, silicatos de calcio y potasio, carbonatos cálcicos, galena, calcopirita e hidróxidos y óxidos de hierro. Sobre la base de la caracterización mineralógica, se realizaron pruebas a nivel de laboratorio que demostraron que la recuperación y la calidad de los concentrados de zinc pueden ser controladas a partir de la dosificación de un colector secundario, cuprocianuro, en la alimentación de la tercera limpieza. Los resultados de las pruebas demostraron que la dosificación de 35 g/t recuperó el 73.80% de Zn; en cambio, la dosificación de 50 g/t recuperó solo el 52.94%. De esta manera, quedó demostrado que tanto la ley como la recuperación de zinc aumentan cuando se dosifica cuprocianuro en mayor cantidad; sin embargo, el exceso de este reactivo tiende a disminuir estos valores.
La inteligencia emocional y su relación con los accidentes de trabajo de los colaboradores de una entidad financiera, 2019
Authors: Zubieta Burga Luz de Maria
Published: September 2024

The main objective of the research was to determine the relationship between emotional intelligence and workplace accidents among the employees of a financial institution in 2019 given the high rate of workplace accidents due to personal factors. A sample of 70 employees was selected and the abbreviated Emotional Quotient Inventory (Bar-On EQ-i) was administered to them. Additionally, workplace accident investigation reports were reviewed to identify the main personal factors that caused workplace accidents. The study found a significant relationship between emotional intelligence and workplace accidents, with a rho value of −0.51. This shows an average negative correlation between emotional intelligence and workplace accidents, meaning that the variables are related to each other in an inversely proportional manner. In other words, the lower the level of emotional intelligence, the higher the number of workplace accidents.

Published: September 2024

Peripheral facial palsy (PFP) is a sudden weakness or paralysis of the facial muscles on one side of the face due to injury of the facial nerve. There are different approaches to PFP in children, which can range from pharmacological, physiotherapy or surgery. Botulinum toxin type A (BoNT) has been used for various conditions, including the treatment of muscle spasticity, migraines and sweating hyperhidrosis. The use of BoNT type A in peripheral facial paralysis has been studied as a potential treatment to improve facial symmetry and reduce complications such as synkinesis. The clinical case presented, reports the results of BoNT in a 1 year old toddler with PFP. Most of the research into BoNT for facial paralysis has been carried out in adult populations, although some larger-scale studies have explored the safety and efficacy of BoNT in children with other neurological and musculoskeletal conditions. Given the limited research on BoNT for pediatric PFP, more studies are needed to establish safety, efficacy, and optimal treatment protocols for this population.
Understanding the complex relationship between population and climate change mitigation

Published: September 2024

The world is currently facing a climate crisis with associated health and plane-tary consequences, and human activity is central to this crisis. Debates on the relationship between population and climate change provide a mixed picture, ranging from demonstrat-ing a clear link between large populous countries and greenhouse gas emissions to pointing to spurious associations between population growth and climate change. We submit that as the interaction between population dynamics and climate change is complex, a nuanced approach to climate mitigation and adaptation strategies is needed. Finding a solution to the climate crisis requires a concerted effort by all nations, whether rich or poor. While there is an urgent need for more industrialized nations to reduce their greenhouse gas (GHG) emissions, poorer countries with fast-growing populations must do their part in climate mitigation even as they pursue economic development. Addressing intertwined issues of population growth, economic development and climate change necessitates purposeful measures and long-term commitments to a world in harmony with nature.

Simvastatin alleviates experimental autoimmune encephalomyelitis through regulating the balance of Th17 and Treg in mice
Authors: Xu Dongsheng , Wang Manxia , Wang Lijuan
Published: September 2024

The aim of this study was to elucidate the therapeutic effect of simvastatin on experimental autoimmune encephalomyelitis (EAE) by regulating the balance between Th17 and Treg cells in mice. C57BL/6 mice were randomly divided into four groups: normal group, EAE group, simvastatin (2 and 10 mg/kg) group, and AG490 group (with AG490 serving as the positive control). Neurological function scores of mice were assessed daily. The four groups received treatments of normal saline, normal saline, and simvastatin (2 and 10 mg/kg), respectively. In the AG490 group, mice were injected intraperitoneally with AG490 (1 mg) every other day, and treatment was halted after 3 weeks. The spinal cord was stained with hematoxylin and eosin (H&E), and immunohistochemical staining for retinoic acid receptor-related orphan receptor γ(RORγ) and Foxp3 (Foxp3) was performed. Spleen samples were taken for Th17 and Treg analysis using flow cytometry. The levels of interleukin-17 and transforming growth factor-β (TGF-β) were detected using enzyme-linked immunosorbent assay (ELISA). In the simvastatin and AG490 groups, recovery from neurological impairment was earlier compared to the EAE group, and the symptoms were notably improved. Both simvastatin and AG490 reduced focal inflammation, decreased RORγ-positive cell infiltration, and significantly increased the number of FOXP3-positive cells. The number of Th17 cells and the level of IL-17 in the spleen were decreased in the simvastatin and AG490 treatment groups, while the number of Treg cells and TGF-β levels were significantly increased across all treatment groups. Simvastatin exhibits anti-inflammatory and immunomodulatory effects, potentially alleviating symptoms of neurological dysfunction of EAE. Regulating the balance between Th17 and Treg may represent a therapeutic mechanism for simvastatin in treating EAE.

Authors: Vechiato Fernando Luiz , Vidotti Silvana Aparecida Borsetti Gregorio
Published: September 2024

Nos últimos anos, as empresas de Perfumaria têm criado soluções tecnológicas baseadas em Inteligência Artificial (IA) visando, entre outras finalidades, otimizar o processo de criação de fragrâncias. Observa-se que a Ciência da Informação (CI), enquanto campo interdisciplinar, pode contribuir com a aplicação de IA na Perfumaria, bem como investigar outros aspectos relacionados ao próprio campo científico nesse contexto. Este artigo objetiva apresentar as contribuições da IA para a Perfumaria e identificar perspectivas de estudo para a CI. Para isso, foi realizada pesquisa bibliográfica no Portal de Periódicos da CAPES e, devido a escassez de literatura científica a respeito das temáticas quando combinadas, foram também utilizados web sites de notícias  ou outros considerados importantes a partir de busca no Google, bem como das próprias empresas de Perfumaria. Os resultados revelam as seguintes contribuições da IA para este setor: otimização da fórmula, análise de tendências e insights baseados em dados; personalização de fragrâncias; sustentabilidade e preservação de aromas; reprodução de fragrâncias; educação; experiência imersiva e interativa, e realidade virtual; design visual e marketing; e tradução de aromas em emoções, cores e palavras. Como perspectivas de investigação na CI foram identificadas as seguintes possibilidades: investigação epistemológica e teórica da informação olfativa; investigação sobre metadados específicos ao campo da Perfumaria; estudo das classificações de famílias olfativas e das descrições de notas olfativas e sua terminologia; elaboração de vocabulários controlados, tesauros e ontologias específicos para o campo da Perfumaria; gestão de dados gerados pelas soluções baseadas em IA; estudos e aplicações de Arquitetura da Informação, de Encontrabilidade da Informação e de Serendipidade; investigação dos estudos olfativos na perspectiva da memória olfativa; e reflexão sobre criação de iniciativas para a difusão da cultura do perfume em ambiências informacionais.

Authors: Vieira Leonardo Araújo , Carvalho Fabio Fortunato Brasil de , Bernardo Debora , Galvão Lucas Lima , Andrade Douglas Roque , Bocalini Danilo Sales
Published: September 2024

Introdução: A atividade física (AF) é uma das pautas estratégicas na agenda da saúde pública e no Brasil é estabelecida enquanto um direito da população. O Ministério da Saúde financia pesquisas orientadas pela Agenda Nacional de Prioridades de Pesquisa em Saúde (ANPPS), portanto, a ANPPS pode aproximar as pesquisas em AF das políticas do Sistema Único de Saúde (SUS). O estudo teve como objetivos analisar: a) a evolução temporal do número, do valor total e valor por pesquisa; b) os eixos; c) as subagendas da ANPPS. Métodos: Trata-se de um estudo descritivo, quantitativo, das pesquisas em AF financiadas pelo Ministério da Saúde no período entre 2002 e 2023, realizado por meio de consulta no repositório público “Pesquisa Saúde”. Foi realizada a análise de tendência temporal do número, valor total deflacionado e valor deflacionado por pesquisa. Os valores absolutos e relativos do número e valor total foram analisados por meio de estatística descritiva. Resultados: Foram financiadas 234 pesquisas em AF e o valor total deflacionado foi de aproximadamente R$ 60,0 milhões, o que corresponde a um investimento médio de R$ 256,5 mil por pesquisa. Esse quantitativo representa respectivamente 3,2% e 1,7% do quantitativo e do valor total deflacionado para pesquisas em saúde. Foram reveladas importantes oscilações no número e no financiamento, com tendência decrescente para o número, valor total e valor por pesquisa no período analisado. O eixo de consequências para a saúde foi o que recebeu o maior número de pesquisas e de recursos financeiros. A subagenda com maior número de pesquisas foi a de doenças crônicas não transmissíveis e a que recebeu o maior montante de recursos foi a de epidemiologia. Conclusão: A AF esteve presente nas pesquisas financiadas pelo Ministério da Saúde, contudo é necessário avançar, principalmente no aumento do montante de recursos e na indução do fomento específico para o eixo de políticas, visando ampliar a produção do conhecimento sobre AF enquanto política pública de saúde.

Dois leitores de Carl Schmitt no Brasil: Francisco Campos e Sérgio Buarque de Holanda
Authors: Veçozzi Regasson Bruno
Published: September 2024

Este artigo tem como questão central interpretar a influência de Carl Schmitt em Francisco Campos e Sérgio Buarque de Holanda. O trabalho apresenta evidências diretas e interpretativas que demonstram esta influência. As recepções são diferentes, mas existe proximidade notável: a valorização do personalismo na política e a proximidade a um projeto de democracia plebiscitária. O artigo argumenta que esta comum referência ajuda a localizar os autores no contexto intelectual nacional do começo do século XX. No caso de Campos, explicita diferenças significativas entre ele e os intelectuais autoritários do período. No caso de Holanda, faz o contrário: mostra sua proximidade com a crítica antiliberal à Primeira República.

The role of expert, institutional and media communication in the pandemic emergency is crucial, since it contributes to spread collective interpretations of the crisis that drive community responses. Based on social representations theory approach, and specifically relying on the notions of collective symbolic coping and polemical social representations, the study presents 10 country-based case studies of public communication with the aim of exploring the social representations of COVID-19 during the first wave of the outbreak. Multiple communication sources from ten countries in five geo-cultural contexts (Europe, North America, Latino America, Asia, Africa) were selected and analysed: institutional websites; international/national/local newspapers and news channels; national/international press agencies; and social media platforms. Results highlighted the prevalence of multi-vocality and polemical social representations, along with outgroup blaming and stigmatisation processes, the use of military and naturalistic metaphors, antinomies, and discourse polarisation. Implications for effective public communication in crisis management are discussed.
Le rôle des experts dans les politiques de lutte contre la COVID-19 au Japon
Authors: Grivaud Arnaud
Published: September 2024

The outbreak of COVID-19 in Japan – the first country to officially report a case outside China – was an opportunity to revive the debate on the relationship between policymakers and scientific experts. The latter, selected and convened in a committee by the government, played a very important role in defining policy responses to coronavirus and in risk communication to the Japanese public. Criticism then fluctuated between the denunciation of a so-called “government of experts” lacking democratic legitimacy (scientifization of politics) and that of “experts at the mercy of the government” whose scientific legitimacy had been manipulated (politicization of science). In order to go beyond these two archetypal representations, this chapter analyses in detail the ways in which experts and their opinions were integrated into the decision-making process, as well as the reactions of the actors involved in the Japanese political and media ecosystem during the COVID-19 pandemic. To do so, this study draws on the literature on knowledge brokers – intermediary actors between science and politics – and on official documents (reports, legal texts, etc.), press articles and testimonies of experts and political actors. This study shows that the relationship between experts and policy-makers was built in a trial-and-error manner, with readjustments according to the balance of power, the perception of their respective roles, as well as the ambivalent and paradoxical reactions of the media, the public and some external specialists. In this context of uncertainty and high “social request for expertise”, although political actors have relied on experts as an essential source of legitimacy for their decisions, the latter have not hesitated to express their disagreements with the government, as well as to demand a clearer division of responsibilities and more transparency, in order to create a decision-making process that would be both more attentive to scientific research and more democratic.
Expert, experts et expertise pendant la crise de la COVID-19 – le cas tchèque
Authors: Kotherová Zuzana , Perottino Michel
Published: September 2024

The COVID-19 crisis has shed new light on a category of experts already well known in the Czech Republic, but long neglected and underfunded: epidemiologists. Faced with challenges that no one could have predicted, one name among epidemiologists stands out above all others: that of Professor Roman Prymula. At the outbreak of the pandemic, he was already part of the ministerial structure, in an important position (deputy minister), a position that had absolutely no link with his expertise as an epidemiologist. The pandemic and the uncertainty of the overwhelmed Czech authorities gave him new and an increasingly important role. When the first peak was over, Prymula left to let other epidemiologists take over. In reality, however, he never really disappeared, and his place - especially in the media - remained strong. Moreover, the prime minister offered him a new position - created ad hoc for him. Finally, during the second COVID wave, he was appointed Minister of Health. Thanks to a series of gradually opening windows of opportunity, Roman Prymula made his breakthrough. His meteoric rise, especially in the media, can certainly be attributed to his expertise and previous positions (soldier, director of a state hospital, links with the pharmaceutical industry), but also to his style (strict, even combative) and high ambition. The transformation of public health from a neglected sector to one of the most important and closely monitored in the health system is also not to be overlooked. Although Prymula was not the only epidemiologist in the Czech Republic, he was perceived as a leading, if not the only, expert. Another problem, less personal but no less important, is that in the Czech Republic we have seen the emergence of protests against the strict containment measures in the event of a pandemic. These protests are coming from other experts, particularly doctors and economists. This raises a new question(s): who can really be called an expert and on what basis, and who is an expert in what? More generally, the aim of the chapter is not only to highlight the meteoric rise of one expert, but also to explain the context, both political and medical-epidemiological, that made this rise possible.
Experts et politiques dans la gestion de la crise de la COVID-19 en Belgique : conflit de territoires et récit médiatique
Authors: Durin Esther , Buidin Baptiste
Published: September 2024

The coronavirus crisis has upset the Belgian institutional balance, leading to an exceptional transfer of power to the federal government. This shift has remarkably put an end to the political crisis that the country was going through since the elections of May 2019. The Belgian management of the Covid-19 first followed its consociational tradition, through interinstitutional dialogue and cooperation with civil society. However, this cooperation was soon shaped by the evolution of relations between politicians and experts and conflicts over the definition of their respective roles and identities. To what extent have the experts assumed a political role? By doing so, did they act as partners, competitors, opponents, or even substitutes to the public authorities, particularly regarding communication with the citizens? To what extent has the collective and consensual ethos of the epistemic community given way to confrontational individual ethos? Drawing on political science research, this paper employs qualitative discourse analysis for studying the relations between politicians and experts during the COVID-19 crisis as painted by the press. Its corpus includes institutional and expert discourses, as well as their coverage by the main Belgian media, between 13 March and 30 November 2020. The analysis first aims at showing the role of self and other representations in the intersubjective construction of meaning and in the building of power relationships between main actors. It secondly focuses on the discursive formation and professional identity they use in their discourse : do they show themselves as knowledge producers or as political decision-makers? The results of the analysis outline three successive configurations. Within the first collegial configuration, political decision remains with the government, even if it relies on scientists’ expertise. Within the second configuration, still marked by collegiality but moving towards co-decision, the experts become partners of the political authorities. The third configuration breaks the collegiality and puts forward individualities – “super-experts” – in competition for decision-making and public communication ownership. The debate moved from consultation bodies’ meetings and press conferences to multiple and more pervasive public spaces. The press coverage of these alternative public spheres emphasises the constant renegotiation of identities between experts and politicians, leading towards a government of experts.
‘To Make Britain Concrete Minded’: Peter László Peri’s London Life in Concrete (1938)
Authors: Aukland-Peck Tobah J
Published: September 2024

In 1938, sculptor Peter László Peri staged a solo exhibition in London titled London Life in Concrete, a selection of sculptural works fabricated out of concrete. Contemporaneous critics enthused about Peri’s experiments with the exciting new medium. Multi-coloured relief works, set on a high ledge that encircled the room, showed scenes of everyday life in the capital: figures of shoppers, builders, and commuters arrayed across flattened backgrounds. The simple format of these sculptures belied the political entanglements of Peri’s chosen material. Rough finishes typify Peri’s concrete works, both those exhibited in London Life in Concrete and those later commissioned to decorate a post-war public housing complex in London. Their explicitly modelled surfaces present the medium as one tied to human labour and equate the work of builder and of artist. London Life in Concrete was sponsored by the Cement and Concrete Association (CCA), a new trade group established to promote the use of concrete in building projects in Britain. This paper traces the history of Peri’s concrete sculptures and the relationship between Peri and the CCA. It reveals the role that Peri’s work played in the commercial project to establish concrete as the architectural material best suited—both practically and ideologically—to the homes of the British working class.
We Need To Talk About Climate: How Citizens’ Assemblies Can Help Us Solve The Climate Crisis
Authors: Smith Graham
Published: September 2024

Citizens’ assemblies bring the shared wisdom of ordinary people into political decision making on the climate and ecological crisis. They are increasingly being used at local, national and even global levels. But with what impact? Can they take us beyond the shortcomings of electoral and partisan politics? Can they make a real difference? This book explains why climate assemblies have captured the imagination of governments and activists alike, exploring the ways they can have a meaningful impact on climate politics. This book charts the development of climate assemblies across Europe and beyond. It explores what ordinary people want, highlighting the ways in which assembly recommendations take us beyond current government policies and offer new visions and directions for change. It shows that not all assemblies are the same and that the context and design of climate assemblies have differed quite profoundly – as have their impacts on policy and public discourse. The book also lays out the key elements needed for climate assemblies to have sustained impact, providing essential insights for anyone wanting to run or advocate for them, and concludes with reflections on what we can expect from assemblies as they evolve. The transition to net zero and climate resilient societies requires deep social and economic transformations that will have significant impacts on citizens’ choices and behaviours. Such a transition needs to engage the public directly and this book shows how climate assemblies can achieve this, allowing us to address the issues we all face together.

Published: September 2024

O foco do trabalho pericial está direcionado em identificar e recolher os vestígios em cenas de crime. Todo o material recolhido pode passar por análises, como de DNA, que possibilita determinar autoria do delito, por meio da utilização de marcadores moleculares. O objetivo do presente trabalho é apresentar um relato de caso, destacando a viabilidade, eficiência do trabalho pericial tanto na cena de crime, quanto no Laboratório de Biologia em união com a investigação policial. Trata-se de um crime sexual envolvendo dois indivíduos do sexo masculino, em cuja cena do crime foram coletadas amostras questionadas para realizar a comparação entre as amostras dos envolvidos. Os perfis genéticos das amostras 2 (unhas postiças da vítima) e 3A e 3B (preservativo do quarto), apresentaram correspondência com a amostra referência da vítima. A amostra questionada 4A (preservativo sanitário parte externa) apresentou uma mistura de material genético de duas pessoas do sexo masculino e já as amostras questionadas 4B (preservativo sanitário parte interna) e 5 (lençol da cama) apresentaram perfil correspondente ao suspeito. É interessante mencionar que o fluxo das atividades investigativas permitiu a busca do suspeito mesmo após o término das análises laboratoriais.  Assim, a garantia de que todos os procedimentos foram adotados para manter a cadeia de custódia, permitiu que novas análises do caso fossem realizadas com sucesso. As análises do suabe oral do suspeito encaminhado posteriormente pelo IML, levaram à sua inclusão juntamente com a vítima, como produtor de um dos perfis genéticos da mistura extraída no preservativo.  Destacam-se pontos importantes para o desfecho exitoso apresentado no presente relato de caso. O primeiro se refere à adequada coleta e preservação dos vestígios biológicos encontrados no local, permitindo a adequada obtenção de produtos de amplificação de DNA nos procedimentos laboratoriais. O segundo se refere à garantia de manutenção da cadeia de custódia, além da integração entre atividades investigativa e pericial durante o trabalho policial.
POLYMERIC COMPOSITES OR NANOCOMPOSITES OBTAINING USING FRICTION MIXING METHOD
Authors: Khabrat Ghulam Rasoul , Puzin Yuri I.
Published: September 2024

Due to the low density and high chemical resistance of polymers compared to metals, the use of polymer composite materials in various industries is growing. On the other hand, because of the low strength of polymers, it is necessary to reinforce them, including micro- and nanoparticles.In recent years, one of the achievements in the industry of plastics and composite materials has been the nanocomposites development and production. They found application in automobile and airplane construction, household appliances and medical equipment.There are various processes for nanocomposite production, such as extrusion and mixing. The limitation of these processes is the high cost, multi-stage production process and the amount of nanosized reinforcing particles (not more than 5 % by mass). Recently, studies on the use of friction with mixing (friction mixing) method for the composite and nanocomposite production were conducted. Using this method for polymer composites and nanocomposites production, in the main polymer sheet a groove of certain sizes is made, and nanoparticles are inserted into this groove. Then the rotating tool is loaded into the sheet and moved along the groove to distribute the particles on the main material.
THERMODYNAMIC INTERPRETATION OF SOLID HYDROCARBON SOLUBILITY IN KETONE-AROMATIC SOLVENTS

Published: September 2024

In modern science and industry, the study of solid hydrocarbon solubility in various solvents plays a key role in optimizing the processes of oil refining, petrochemistry and other industries. Understanding the interactions between the components of mixtures is critical to developing efficient production technologies and ensuring high quality final products. The study of experimental and calculated data, as well as a detailed analysis of literature sources, led us to a convincing conclusion that the slope of the solubility graph really plays an important role in determining patterns in solubility processes. This criterion opens up new perspectives for the study and understanding of physicochemical processes associated with solubility. Experiments and calculations were carried out, and the slope of the solubility graph was determined for each solvent composition. The technique is based on an analysis of the dependence of the cloud point of the solution on the content of solid hydrocarbons and the composition of the solvent. This work examines the study of the solubility of solid hydrocarbons in the most common ketone-aromatic solvents. Experimental and computational studies aimed at establishing patterns in the dependence of the tangent of the angle of inclination on the solvent composition and other factors are described. The research results are important for optimizing technological processes and increasing production efficiency in various industries. One of the important parameters characterizing the solid hydrocarbon solubility in solvents is the slope of the solubility curves. This parameter allows one to judge the nature of the solvent, its ability to interact with dissolved components, as well as the rate of temperature change required for paraffin precipitation.The considered problem is related to the need to study the influence of the solvent composition on solid hydrocarbon solubility processes. The hypothesis is that the slope of the solubility graph can provide insight into the nature of the solvent. In this paper the results of experiments and calculations that confirm this hypothesis are presented.
