Unification of Ukrainian Society in a Postwar Period as a Preventive Mechanism to Avert the Crisis of State
Authors: Lavrynenko Hanna , Donaj Łukasz
Published: January 2024

The study involves the analysis of unification of Ukrainian society in a postwar period to prevent the crisis of state system. It is claimed, that upon the war termination the issue of creation of universal Ukrainian society forming model arises, which is supposed to represent a symbiosis of foundations of nationwide well-being and prospects of Ukraine strategic development. It is shown, that the existent division of society into those who stayed in Ukraine and those who left for other countries can scale up in a long run. The loss of conceptual univocity in the course of developing such categories as “victim,” “patriot,” “traitor” and “savior” in civil society bears evidence to the mobility of self-identification process of existing population clusters and possible appearance of new categories of populace in the not so distant future. The rationalization for human capital is provided as well as the necessity of having regard to the mentioned factor while elaborating the postwar country development strategy. Special attention is paid to the problem of implementation of repatriation policy. Its types are defined, and the mostly acceptable options for Ukraine are characterized, including the direct and active or in direct and mediated state’s stimulation of nationals’ returning to the ethnical Homeland. Based on the conducted analysis of current experience of European countries, it was concluded that it is the controlled process of return migration that is the key component of consistent country development.

Heat transfer within nonequilibrium dense aluminum heated by a heavy ion beam
Authors: Song Chiwan , Lee Seongmin , Bang Woosuk
Published: January 2024

Energetic laser-accelerated ions can heat a small solid-density sample homogeneously to temperatures over 10,000 K in less than a nanosecond. During this brief heating time, the electron temperature of the sample rises first, and then the ion temperature increases owing to the heat transfer between the hot electrons and cold ions. Since energy deposition from the incident heavy ion beam continues concurrently with the electron-ion relaxation process within the heated sample, the electron and ion temperatures do not reach equilibrium until the end of the heating. Here we calculate the temperature evolutions of electrons and ions within a dense aluminum sample heated by a laser-accelerated gold ions using the two-temperature model. For these calculations, we use the published stopping power data, known electron-ion coupling factors, and the SESAME equation-of-state (EOS) table for aluminum. For the first time, we investigate the electron and ion temperature distributions within the warm dense aluminum sample and the heating uniformity throughout the entire heating period. We anticipate that knowledge of the temperature evolution during heating will allow for the study of the stopping power, thermal conductivity, EOS, and opacity of warm dense matter heated by an energetic heavy ion beam.

Published: January 2024

Objectives

Neuronal ceroid lipofuscinosis type 11 (NCL11) is a rare disease that presents with progressive cognitive decline, epilepsy, visual impairment, retinal atrophy, cerebellar ataxia and cerebellar atrophy. We present herein a case of NCL11 in a patient diagnosed with neuromotor developmental delay, epilepsy, bronchiolitis obliterans and hypothyroidism.

Case presentation

A 4-year-old male patient was admitted to our clinic with global developmental delay and a medical history that included recurrent hospitalizations for pneumonia at the age of 17 days, and in months 4, 5 and 7. Family history revealed a brother with similar clinical findings (recurrent pneumonia, hypothyroidism, hypotonicity, swallowing dysfunction and neuromotor delay) who died from pneumonia at the age of 22 months. Computed tomography of the thorax was consistent with bronchiolitis obliterans, while epileptic discharges were identified on electroencephalogram with a high incidence of bilateral fronto-centro-temporal and generalized spike-wave activity but no photoparoxysmal response. Cranial MRI revealed T2 hyperintense areas in the occipital periventricular white matter and volume loss in the white matter, a thin corpus callosum and vermis atrophy. A whole-exome sequencing molecular analysis revealed compound heterozygous c.430G>A (p.Asp144Asn) and c.415T>C (p.Cys139Arg) variants in the GRN gene.

Conclusions

The presented case indicates that NCL11 should be taken into account in patients with epilepsy and neurodegenerative diseases.
Martyrdom in the Age of Mechanical Reproduction
Authors: O’Sullivan Lucy
Published: January 2024

A tradition of martyr photography flourished during Mexico’s religiously motivated Cristero War (1926–29). Graphic photographic prints and postcards depicting executed Catholic activists and priests circulated widely during the conflict as a form of antigovernment propaganda, justifying comparisons of the Cristeros to the earliest persecuted Christians. Taking into account the iconographic and material features of these photographs as well as the medium’s particular ontological qualities, I explore how Cristero martyr images fulfilled comparable functions to early martyr narratives and relics by providing a compelling visual testimony and material trace of the martyr’s sacrifice. In these photographic images, the testimonial value and heightened verisimilitude of the early martyr text finds a parallel in a graphic documentary visual language that emerged with the increased mediatization of violence during the Revolution (1910–17). At the same time, these visual mementos sought to appeal to viewers on an affective level by drawing from long-standing iconographic vocabularies and material modes of devotional experience, most notably the tactile intimacy of the portable relic. Approaching the Cristero conflict from the analytical perspectives of visual culture and material religion, my research sheds new light on how Catholic activists conceptualized and justified violent sacrifice in their struggle for religious freedom while also making novel contributions to the history of Mexican photography. These complex visual artifacts reveal how Cristero propagandists utilized familiar religious images and concepts to provide a meaningful religious framework for their activism while also adapting strategies of martyr memorialization to the age of mechanical reproduction.

During the first half of the twentieth century, representing the body was a pivotal means to reimagine national and regional identities at a moment when the legacies of colonial power structures were coming under increasing scrutiny. The body became a vehicle through which artists could envision new, expanded, and intersecting notions of race, gender, class, nation, and region. Through close readings of single images created in eight different countries—Guatemala, Bolivia, Brazil, Uruguay, Mexico, Venezuela, Colombia, and Cuba—this Dialogues contains essays by scholars from South America, Europe, and the United States that reveal the capaciousness for the body to encapsulate local racial, class, and gender dynamics, to illuminate regional and national politics, and to embody divides between socially progressive politics and entrenched conservative social systems and hierarchies. The authors pay careful attention to form, subject, and style to demonstrate the potency of modernist figuration, an international and vibrant visual language, to interrogate issues of race, ethnicity, indigeneity, and gender. Together, the essays point to the critical particularities of iconography, context, and style. In so doing, they reinforce the ability of representation to resonate in multivalent ways and assert the power of the image to stir debate, fix (or challenge) convictions, and raise questions about histories. The authors harness the power and visual variety of realisms and representation in Latin America, revealing the malleability of the modernist body and its efficacy as a carrier of meaning and locus for debates about power, progress, and identity.

Who Founded Quilcapampa?
Authors: Jennings Justin , Knobloch Patricia , Gibbon Elizabeth
Published: January 2024

During the Middle Horizon (600–1000 CE), the Wari state’s influence expanded across a broad swath of the central Andes. To better understand the organization of this state and its relationship to outlying regions, we conducted a social network analysis with a database of human images—cataloged as “agents”—as depicted on Wari-associated art. Agent analyses depended on trained, visual acuity for interpreting ancient artistic expressions that distinguished individual identities among various Middle Horizon cultures. The social network analysis used agent locations and co-occurrences on the same object to model the period’s complex social dynamics. The resulting networks suggest a Wari political structure that was more fractured and decentralized than previously imagined during the early Middle Horizon. This article explores aspects of these networks in relationship to four agents excavated at Quilcapampa, a short-lived Wari-affiliated enclave founded during the ninth century on the coastal plain of southern Peru. Considering the place of these agents within Middle Horizon social networks—when combined with what is known about Quilcapampa, the southern Peruvian coast, and the period in general—allows for a reconstruction of who founded Quilcapampa and the possible reasons for the settlement’s founding. The results provide insights into ninth-century changes to Wari’s organization that would be difficult to obtain from purely descriptive analyses of each agent, demonstrating the utility of social network analysis of the human image for investigating political relationships in societies without writing.
On Vertices and Ruptures
Authors: Binnie Mari Rodríguez
Published: January 2024

The 1970s presented a crux in critical discourse on the state of artistic vanguardism in Brazil, one set against a regional repositioning of intellectual and curatorial strategies in response to the ongoing Cold War. This article delves into exhibitions and criticism during this fraught period in order to elucidate the reverberations between the political imperatives for the region’s artists and critics, and the institutionalization of the now canonical narrative of Brazilian modern art. The seventies saw the cementing of the history of Brazilian modernism, a process that engaged but also contradicted the surge in Latin Americanism then occurring in response to the region’s charged political context. Yet a consequence of writing this canon was also the ensuing neglect of conceptual practices that emerged during this period, manifesting as collective and collectivist expressions of a shared regional precarity.

Published: January 2024

This study focuses on the role of concrete cover in enhancing the torsional resistance of peak load in under-reinforced fibrous high-strength concrete beams. In this study, the primary variable that varied from 17 mm to 53 mm was the concrete cover thickness. Four rectangular solid beams were cast and tested to determine the effect of concrete cover thickness on the behaviour of under-reinforced fibrous, high strength concrete beams subjected to pure torsional loading. The test results revealed an 80.6% improvement in the torsional resistance at peak load. In addition, at maximal loads, the twisting angle, shear strain in concrete, transverse reinforcement strain, and longitudinal reinforcement strain were reduced by 70.2%, 90%, 50.6%, and 34.5%, respectively.  It is therefore possible to draw the conclusion that the concrete cover has a new function, which is an improvement in torsional resistance at ultimate load that is in addition to protecting the reinforcement from corrosion.

Motorcycle fatalities comprised of 60% of the total fatalities in Malaysia. Weaving between traffic and speeding are among the contributors to the high motorcycle fatalities and there is not much understanding of the. This study was conducted with the objective to determine the lane preference of motorcyclists within various road cross-section and speed of motorcyclists when using the lanes. The lane usage was recorded with video camera and video was playback to count the count of motorcyclists using their respective lane. As for speed of motorcyclists, spot speed measurement was conducted covertly to avoid affecting motorcyclists’ behaviour. A total of 11 locations with different cross-section designs throughout the Malaysia was identified for observation. The empirical results show that more than 95% of the motorcyclists travelled on the non-exclusive motorcycle lane (NEML) when the NEML is presence at 2 lane single carriageway section. Meanwhile, paved shoulder about 2.2-2.3m wide was found to be used by majority of motorcyclists (75%). Apart from obtaining the lateral travel position of the motorcyclists, the spot speed data were also collected. The speed results revealed that motorcyclists travelled statistical significantly slower on NEML or Paved shoulder (PS) than on main travel lane. The findings of this study conclude that NEML and paved shoulder can affect motorcyclists to ride slower and thus enhance the safety of motorcyclists in term of speed exposure. In addition, the NEML and PS separate motorcyclists from other motorized vehicles which could reduce the risk of crashes of motorcyclists with another vehicle. Even though provision of NEML incurs high costs, however in long term, NEML would prove to be one of the most efficient allocation resources in reducing motorcycle crashes. However, further studies need to be carried out on the use of paved shoulder by motorcyclists.

Overall, from a Continual Quality Improvement (CQI) perspective, this study is important to improve, develop and evaluate the teaching, learning and assessment methods adopted for engineering education.
Numerical Study on the Torsional and Lateral Vibrations of Double Universal Joint Driveline System
Authors: Mohd Hazri Omar  , Ab Rahim Muhajir , Md Rejab Mohd Noor Arib
Published: January 2024

Utilizing a universal joint can lead to significant vibration within a driveline system. This study presents a model for analyzing the torsional and lateral vibrations of a driveline connected by a double universal joint. The governing equations of motion are derived, and the Runge-Kutta method computes steady-state responses across a spectrum of input rotational speeds. The focus is to examine the effect of system parameters, including static angular misalignment, load torque, and lateral stiffness. Relative amplification is used to analyze the effects of parameters on system vibration. Results indicated that the second-order component of input rotational speed induced by the universal joint was the factor that caused the vibrations. For the considered system, static angular misalignment significantly impacts both the torsional and lateral vibrations. Increasing the angular misalignment from 15° to 30° results in a threefold increase in lateral vibration amplification, while torsional vibration amplification is increased by nearly two times.  The effect of load torque is almost linearly proportional to torsional vibration but is nonlinear to lateral vibration. Thus, lateral vibration is significantly impacted compared to torsional vibration for higher load torque. Changing the stiffness leads to a modification of the natural frequency. Increasing the lateral stiffness shifts the critical speed to a higher speed range, resulting in reduced lateral vibration amplitude.  It is demonstrated that a slight fluctuation in angular misalignment due to lateral vibration will not affect the torsional vibration even if both vibrations are coupled. The findings may enhance understanding of how changing system parameters affects vibration.

THE EFFECT OF INTELLECTUAL CAPITAL ON OPERATIONAL PERFORMANCE AMONG DEPOSIT MONEY BANKS: MEDIATED BY INNOVATION
Authors: Adamu Danladi Abdulhamid , Alkali AU , Salisu Ali Hamza
Published: January 2024

The banking sector, like many other service industries, is frequently characterized by a high level of rivalry, driving enterprises to come up with innovative ideas and strategies to improve their chances for success. Over the years, Nigerian Deposit Money Banks' operational efficiency has been bad in terms of per customer service timing, time spent at the bank, and an unreliable network, among other things. This tendency might be linked to a lack of investment in the bank's intangible assets, often known as intellectual capital. This study examined the mediating effect of innovation in the relationship between intellectual capital (IC) and operational performance (OP) of deposit money banks (DMBs) in the Nigerian Banking sector. The study was built on the idea of Resource Base View Theory (RBV) and Human Capital Theory. Three dimensions of intellectual capital namely: Human Capital (HC), Structural Capital (SC) and Relational Capital (RC) were used. Cross-sectional survey design was adopted in this study and structured questionnaire was used to collect data from the operational employees of all the 13 DMBs operating in Jalingo, Taraba state, Nigeria. 399 questionnaires were distributed out of which 357 usable questionnaires were retrieved. The data was analyzed using PLS-SEM. Results of the analysis showed that all the components of IC (HC, SC and RC) have significant positive effect on operational performance of DMBs in Jalingo with human capital (HC) having the highest influence. In addition, results of the analysis also show that innovation mediates the relationship between intellectual capital and operational performance of DMBs. The study concludes that innovation (INV) plays a mediating role in the relationship between intellectual capital and operational performance of DMBs.

Published: January 2024

Manufacturers are increasingly substituting additive manufacturing for conventional manufacturing methods due to their ability to produce complex shapes. Polymer-based filament materials can be printed efficiently and inexpensively with fused deposition modeling. Coatings tend to augment the appearance of 3D printed objects as well as protect them from environmental influences. It is imperative to realize the physical and chemical properties of polymeric material like Acrylonitrile Butadiene Styrene (ABS) surfaces so as to design an optimal surface system. This work relates to the development of surface coatings on 3D-printed ABS parts. L9 orthogonal array was used with three 2 level factors for printing the samples. Specifically, the research compares surface characteristics of 3D-printed uncoated and coated ABS specimens. An aqueous solution containing Tricalcium phosphate and Chitin clear solutions in a 70:30 ratio was applied through immersion technique to create hydrophobic coatings. The coated and uncoated samples were characterized by employing various characterization tests, including dimensional accuracy (DA), surface roughness (SR), water contact angle (WCA), absorbency tests, scanning electron microscopy on fabricated parts. Assessment of wettability of 3D printed samples and impact of coating was accomplished via static contact angle measurements. In order to assess DA and SR before and after coating, digital vernier calipers were used in conjunction with a profilometer. In accordance with ASTM D570-98, water absorption tests were conducted for specified time. Results of investigation post coating showed no variation in dimensional accuracy, reduced SR and increased in WCA by ≥ 100 ̊. A reduction in water retention was observed after coating based on water absorption tests.

Authors: Datta Bharadwaz Yellapragada  , Kumari A. Swarna
Published: January 2024

The current work aims at characterizing the premixed charge compression ignition (PCCI) combustion with regression-based approach using response surface methodology. PCCI operating parameters such as load, pilot injection timing, main injection timing, pilot injection quantity, exhaust gas recirculation and injection pressure are considered as input variables. Engine performance indicators such as brake thermal efficiency, brake specific fuel consumption, carbon monoxide (CO), hydrocarbon (HC), oxide of nitrogen (NOx), smoke emissions, combustion phasing and combustion noise metric ringing intensity are considered as output responses. Experimental results validate the optimal solution from response surface methodology approach, and good agreement is found between mathematical models and experimental results. Comparative examination of optimized PCCI combustion versus conventional combustion showed a 66% and 44% decrement in NOx and smoke emissions. Except for CO and HC emissions, the percentage penalty of other responses with PCCI combustion is less than 10%. In addition to ringing intensity another combustion noise metric combustion noise level is computed from Fast Fourier Transform (FFT) analysis of cylinder pressure trace. A combustion noise level of 73.26 dB is obtained at optimized conditions.

Published: January 2024

This paper elaborates about the analyzing of Intelligent Quotient (IQ) and Emotional Quotient (EQ) of an engineering student based on Electroencephalogram (EEG) or brain signals using a computing tool such as MATLAB. The influence of individual’s IQ and EQ on the development of innovative thinking is significant. An IQ alone is not adequate to measure the success of a person. An EQ somehow is found to have a substantial correlation with individual’s performance which shows that both IQ and EQ are important in determining the character and manner of individual’s thinking skills. The main objective of this project is to analyze the output of EEG signals produced by an engineering student based on their IQ and EQ level. A comparison of which quotient influences the student’s thinking skill is also observed in this study. In this project, a single channel EEG amplifier is used to record the EEG signals from 6 different subjects with three different conditions: while not doing anything, during an IQ test and during an EQ test. The data is recorded using the EEG sensors with Unicorn Recorder software that is connected to the amplifier while recording is run. The result of the experiment also explained in terms of the mean value and standard deviation of the EEG bands for each subject and condition. The results of the study conclude that the IQ level of an individual is affected by the Beta band of the EEG signals. Meanwhile, Alpha band of the EEG signals is more dominant in the determination of EQ level of an individual. When Alpha band is higher than Beta band, it shows that the subject is dominant to an EQ dominant person. If Beta band is higher than Alpha band, then IQ is the dominant quotient for the subject. The highest k-NN classification accuracy is obtained at 80:20 classification with 81.84% accuracy using Mean features and 79.53% accuracy using Standard Deviaton features. This study also included the development of Graphical User Interface (GUI) in MATLAB. The GUI is used for the classification of the chosen EEG features. Theta, Alpha, and Beta power band are observed from the EEG signals to identify brain activity. In addition, IQ and EQ analyzer is constructed using Arduino microcontroller once the analysis of the EEG signals are done through GUI.

In advanced pancreatic neuroendocrine neoplasms (PanNEN), there are little data detailing the frequency of genetic alterations identified in cell free DNA (cfDNA), plasma–tissue concordance of detected alterations, and clinical utility of cfDNA. Patients with metastatic PanNENs underwent cfDNA collection in routine practice. Next-generation sequencing (NGS) of cfDNA and matched tissue when available was performed. Clinical actionability of variants was annotated by OncoKB. Thirty-two cfDNA samples were analyzed from 25 patients, the majority who had well-differentiated intermediate grade disease (13/25; 52%). Genomic alterations were detected in 68% of patients and in 66% of all cfDNA samples. The most frequently altered genes were DAXX (28%), TSC2 (24%), MEN1 (24%), ARID1B (20%), ARID1A (12%), and ATRX (12%). Twenty-three out of 25 (92%) patients underwent tumor tissue NGS. Tissue–plasma concordance for select genes was as follows:DAXX (95.7%), ARID1A (91.1%), ATRX (87%), TSC2 (82.6%), MEN1 (69.6%). Potentially actionable alterations were identified in cfDNA of 8 patients, including TSC2 (4; level 3b), ATM (1; level 3b), ARID1A (2; level 4), and KRAS (1; level 4). An ETV6:NTRK fusion detected in tumor tissue was treated with larotrectinib; at progression, sequencing of cfDNA identified an NTRK3 G623R alteration as the acquired mechanism of resistance; the patient enrolled in a clinical trial of a second-generation TRK inhibitor with clinical benefit. In metastatic PanNENs, cfDNA-based NGS identified tumor-associated mutations in 66% of plasma samples with a high level of plasma-tissue agreement in PanNEN-associated genes. Clonal evolution, actionable alterations, and resistance mechanisms were detected through circulating cfDNA genotyping.

У запропонованій статті автор висвітлює положення та діяльність греко-католицького духовенства у Чернівецькій губернії 1914–1917 рр. Представлено геополітичну ситуацію та нормативну базу політики контрольованої віротерпимості російської адміністрації щодо уніатського духовенства на окупованих територіях. На основі аналізу облікових, розпорядчих та звітних матеріалів проана- лізовано: 1. Вплив війни на чисельність греко-католицького духовенства у восьми деканатах Стани- славіської єпархії; 2. Релігійну, громадську, представницьку, опікунську діяльність священників УГКЦ. Встановлено, що саме греко-католицьке духовенство стало однією з причин провалу політики царської влади щодо ліквідації української ідентичності та включення краю до складу Російської імперії. Джерельною базою для статті стали документальні матеріали з фондів державних архівів Івано-Фран- ківської, Чернівецької та Тернопільської областей.

ТЕРЕНИ БУКОВИНИ У МОЛДАВСЬКІЙ ПОЛІТИЦІ КОРОЛЯ АВГУСТА ІІ СИЛЬНОГО (1697–1699 рр.)
Authors: BALUKH Oleksiy
Published: January 2024

Мета статті полягає у розкритті молдавської політики короля Августа ІІ Сильного, яка полягала у підпорядкуванні території Дунайських князівств Речі Посполитій у 1697–1699 рр., а також визначення на основі аналізу доступних джерел та монографічної літератури її наслідків для населення та економіки північномолдавських земель. Наукова новизна полягає у комплексному дослідженні полі- тики Августа ІІ у прикордонних з Річчю Посполитою територіях Північної Буковини на початку його правління. Встановлено, що північномолдавські землі стали розмінною монетою у зовнішній політиці монарха Речі Посполитої щодо Молдавії, оскільки за умовами Карловицького миру Молдавія залишалися в системі підвладних Порті територій, а Річ Посполита звільняла зайняту під час війни з османами пів- нічну частину Молдавської держави в обмін на Кам’янець та Поділля. Внаслідок військових дій Хотин- ська фортеця зазнала руйнувань і втратила роль форпосту на польсько-молдавському прикордонні. Усвідомлення того, яке значення при цьому відігравали буковинські землі, та які процеси відбувалися тут у вказаний період, є важливим для розуміння ситуації, що склалася. Результати дослідження важ- ливі для оцінки військово-політичної ситуації довкола Буковини у зв’язку з протистоянням Молдавії переважаючим силам Речі Посполитої та Османської імперії, а пізніше Австрії та Московії, про що буде йтися у наступних розвідках автора.

“La isla en peso”. Espacio literario e intertextualidad en Wide Sargasso Sea, de Jean Rhys
Authors: Goenaga Conde Beatriz María
Published: January 2024

El objetivo fundamental de este artículo está dirigido a valorar las funciones de la intertextualidad en la construcción del espacio insular caribeño en WideSargasso Sea, de la escritora dominiquesa Jean Rhys. Por tal motivo se analizaron las relaciones intertextuales entre Jean Eyre, de Charlotte Brontë, y Wide Sargasso Sea, de Jea Rhys, con énfasis en la isla en tanto espacio literario presentado de manera explícita. Como resultado se pudo constatar que la principal función de la intertextualidad en dicho texto responde a la intención calibanesca y desmitificadora de desmonte de los arquetipos en los que la imagen del otro ha sido construida en el discurso del poder. De igual manera, el presente análisis permite develar la riqueza de las connotaciones otorgadas en el texto al espacio isla y a sus significados añadidos. La red de significaciones encontradas refuerza su identidad cultural caribeña.
Identidad, memoria y la búsqueda del padre desaparecido desde la óptica de dos cineastas guatemaltecos
Authors: Contreras Ana Yolanda
Published: January 2024

Este artículo1 explora dos obras cinematográficas guatemaltecas, Polvo (2012) y Nuestras madres (2019), dirigidas por Julio Hernández Cordón y César Díaz correspondientemente. En ambos largometrajes la denuncia sobre la violación de derechos humanos durante el pasado conflicto armado guatemalteco, la búsqueda de padres o familiares desaparecidos y sus secuelas en las víctimas constituyen la temática central. Por tanto, el análisis se centra en la importancia que tiene la búsqueda del padre desaparecido en los hijos, quienes, a raíz de esta vivencia traumática, experimentan un vacío identitario, así como estragos individuales provocados por la falta de la figura paterna. Por otro lado, también se analizan el trauma y el silencio de las madres sobrevivientes como remanente del miedo/terror experimentado durante el conflicto armado, pero también como un mecanismo de protección para sus hijos. En especial, el análisis se auxilia teóricamente con el extenso trabajo realizado por el sociólogo uruguayo Gabriel Gatti sobre la desaparición forzada.

Xanthoceras sorbifolium Bunge oil exhibits favorable characteristics such as excellent low temperature fluidity, high flash point, and degradability. However, it also suffers from drawbacks including low kinematic viscosity at low temperatures and significant loss of kinematic viscosity at high temperatures. In view of these characteristics of X. sorbifolium oil, it was modified in this work with a combination of ethyl cellulose (EC), montmorillonite (MMT), and cetyltrimethylammonium chloride (CTAB). The effects of temperature, time, and additive content on the rheological properties of lubricating oil were studied. The kinematic viscosity of the prepared lubricating oil reached up to 433 mm2/s at 40 °C and 51.1 mm2/s at 100 °C. The coagulation point could be reduced to -25 °C, the friction coefficient was 0.026, and the average wear spot diameter was 0.81 mm, The anti-friction performance was enhanced, and the anti-wear performance decreased somewhat. The prepared lubricating oil had the characteristics of high kinematic viscosity at high temperature and excellent rheological properties at low temperature. It also met the energy and environmental application requirements of a green, environmentally friendly, and biodegradable sustainable development strategy. This study greatly broadens the application range of lubricating oil.
