Research of the Quality of Motor Oils of Heavy Dump Trucks during Operation under Conditions of High Temperatures
No full textStudies of the contamination of lubricating oils operating in engines of heavily loaded mining transport equipment during operation in hot climates (air temperature in summer exceeds +50° C) and high dust content of air (the length of quarry roads is 65-70 km) show that motor oils are intensively contaminated with mechanical impurities. Dust is the determining cause of wear in piston engines, so its amount in the air significantly affects their reliability. The Muruntau quarry is a unique mountain object. Its depth today is more than 620m. The width is more than 2.9 km and the length is more than 3.2 km. The length of quarry roads is 65-70 km. The amount of dust increases to 5–10 g/m3, i.e. is several orders of magnitude higher than the air dust content. The purpose of this work is to study the influence of air dust on the performance of engine parts in operating mining and transport equipment. For this purpose, the characteristics of working motor oils SAE15W-40, API CI-4 selected from the engine of BelAZ-7513, BelAZ-75307, BelAZ-75310 dump trucks were determined. Taking into account all the experimental data we have received, we recommend additionally adding additives to the engine oil, which consists of phosphorus 4.5%, sulfur 14%, molybdenum 10.6%. According to the results of laboratory studies, when adding MoPS-14 3% additive to SAE15W-40, API CI-4 motor oil, the physicochemical indicators gave a positive result compared to SAE15W-40, API CI-4 base oils

Enhancing Thermal Performance of Solar Parabolic Through Collector by using Corrugated Absorber Tube
No full textThis study investigates the potential for enhancing the thermal efficiency of solar Parabolic Trough Collectors (PTCs) by employing corrugated absorber tubes. Through the CFD modeling, the research explores the impact of corrugated designs on heat transfer efficiency and overall system performance. Computational fluid dynamics (CFD) model simulations are carried out with COMSOL Multiphysics 6.1 with Time-dependent solver configuration. Results indicate that corrugated absorber tubes offer significant improvements in thermal efficiency, with enhanced heat transfer characteristics and increased energy conversion efficiencies compared to traditional absorber tubes. Temperature variations and useful heat gains of the absorber tube is presented in the discussion section of the article. The findings suggest promising opportunities for advancing solar energy technologies and promoting sustainable energy solutions
The influence of the Quality of Hydraulic Fluid and its Operating Temperature on the Reliability of Automatic Transmissions
No full textThis article is devoted to the analysis of the influence of the quality of hydraulic fluid and its temperature on the reliability of automatic transmissions (AT). Based on the completed analytical review and operational observations, the authors of the article recommended: the introduction into the hydraulic system of highly efficient filters for hydraulic fluid (oil) with a screening fineness of no more than 10 microns. Also recommended for hot climate conditions is the frequency of hydraulic fluid replacement, which should be 15-20% lower compared to non-hot climate conditions
Drawing up a Road Plan in Difficult Sections
No full textThe railway is the busiest transport and properly designed and used will further improve efficiency. For this reason, this article gives the most convenient transition model in the section of rail lifting from one plane to another. That is, in order for the movement of the train in the ascent section to be smooth, the trajectory in the turn section must be an arc of a circle. The plane in which the train stands should be an attempt at this circle. It is optimal that the upper plane is also in the wobbling position along the circular arc on the lifting par
Biopsychosocial aspects of COVID-19 among individuals living with diabetes in Mali: A cross sectional analysis
No full textWith a view to better documenting care practices influenced by the lifestyle habits of diabetics, research is being carried out to analyse the biopsychosocial aspect of COVID-19 in diabetics in Mali from 2020 to 2023. This cross-sectional study describes the biopsychosocial aspect of COVID-19 among diabetics in Mali between March 2020 to December 2023. Findings suggest an association between psychologist consultation and physical exercise, alcohol and cigarette consumption (p <0.05) during the pandemic. As well, we found an increase in diabetic complications and physical exercise, alcohol consumption and cigarette smoking (p <0.05) during the pandemic. Lifestyle habits during COVID-19 have altered the health status of individuals living with diabetes
Guerre et Paix
No full textParmi les tambours de la guerre et l’effondrement des institutions médicales au Liban, ces deux poèmes contrastent les péripéties d\u27une enfance traumatisante durant la guerre civile à la paix paradoxale d’une naissance paisible dans une famille unie, au sein d’un hôpital français de Beyrouth.
Amidst the sounding drums of war and the near complete collapse of the healthcare infrastructure in Lebanon, these two poems contrast a traumatizing childhood during the civil war to the paradoxical peace of a peaceful birth within a united and loving family at a French hospital in Beirut
Beyond the \u27God-trick\u27: Multisensory Storytelling and Documentary Epistemology
No full textAs immersive media develops, creative technologies and the creative practices that they enable are introducing forms of multisensory experience which displace the visuality that has dominated media to date, reflecting a cultural emphasis on sight that, as Brian Winston has shown (1996) can be traced right back to the invention of perspective in the Renaissance. Immersive media experiences can be multi-modal and multi-sensory, with content reaching us not just through our eyes and ears but through forms of embodied experience including smell, touch and proprioception. These mediated forms of sensory engagement now intersect with documentary themes within Virtual Reality (VR), Mixed Reality and Augmented Reality experiences, prompting a discourse concerned with the expanded fields and rhetorical and political affordances of immersive nonfiction (Kim, 2022; Rose, 2018).
This paper will offer an initial mapping of projects that harness the opportunities represented by these multisensory registers. Through reference to case studies by The Feelies (Munduruku 2017), Anagram (Messages to a Post Human Earth 2021) and Marshmallow Laser Feast (We Live in An Ocean of Air 2018) we will explore how the entanglement with media allowed by novel sensory affordances is being deployed. Expanding on the entanglement of the immersant and the multi-modal media interface we will investigate what multisensory forms of storytelling might bring to the documentary project of illuminating, critiquing and reshaping our shared world.
With media criticism dominated by visual and textual interpretation, we will turn to phenomenological film criticism as a starting point for an analysis of the forms of knowledge that emerge when documentary engages senses beyond the visual and aural modalities of the 20th century. We will draw on Laura Marks’ (2000) phenomenological conceptualisation of the body and embodied knowledge within cinematic experience. Marks calls the forms of knowledge derived from embodiment ‘tactile epistemologies’. These, she writes, ‘conceive of knowledge as something gained not on the model of vision, with its connotations of dominance, but through physical contact’. The paper will propose tactile epistemology as a rich conceptual framework through which to consider the forms of knowledge production at play within the multisensory engagements emerging within VR and MR nonfiction.
With reference to content that engages environmental themes, we will explore the hypothesis that this generation of multisensory immersive experiences holds potential for an epistemological shift from a nonfiction media that relies on the ‘god-trick’ (Haraway 1988) of seeing everything from nowhere towards a paradigm based in situated knowledge. In this model, meaning emerges as the immersant explores their media surround and pays attention to the effects that their multisensory interaction produces. Knowledge isn’t gained through mastery but through openness, even vulnerability, in what Marks has called ‘a compassionate involvement with the world’ or Michael Taussig has termed a ‘yielding-knowing’. Within this framework, entanglement is not only a characteristic of the multisensory interface and its way of producing meaning, but a documentary methodology that encourages a relational perspective on the human position vis a vis the environment and the more-than-human world.  
What’s Our Name? : Migrant Communities, Identity and Football in Latin America. Decolonising the British informal Empire in Chile and beyond
No full textArgentinian legend, Diego Maradona, stated: “Football isn\u27t a game, nor a sport, it\u27s a religion.” (Growler, 2018) Viewed in this way, Benedict Anderson’s theory of ‘imagined communities’ – proposing nationalism is more about cultural construct – suggests we can understand football allegiances within migrant communities as “a deep, horizontal comradeship” which culturally resonates more profoundly than merely supporting a chosen team linked to ethnic identity. (Anderson, 2016)
Sport provides the portal for this interactive participatory documentary, through which social history and cultural aspects of identity, citizenship and community entanglements are explored, while charting the spread of ‘the beautiful game’ by migrant communities across Latin America.
Chile’s premier football league features four clubs established by migrant populations: Club Deportivo Palestinos, founded in 1920, Audax Italiano (1910), Union Espanola (1897), and... Everton de Vina del Mar (1909). During the last 150 years there have been numerous recorded clubs called Everton across Latin America. Vina del Mar is one of seven that still exist. All these clubs have a direct connection to Everton FC in Liverpool, founded in 1878, just a few years before the first Latin American team bearing the same name. No other club has such a storied link to the continent.
The formation of these clubs is rooted in the industrialisation of Latin America in the late 1800s and early 1900s. They reflect the arrival of thousands of merchants and entrepreneurs associated with banking, mining industries, utility companies and railway construction; employing tens of thousands of railway engineers and labourers, many of whom migrated from Merseyside to establish the first rail networks serving mercantile export throughout Chile, Argentina, Uruguay and Paraguay. (Reeder, 2020)
A major trading hub in the British informal Empire, Valparaíso became the cradle of football in Chile. This is documented in the Foxley family archive, to which the research project has exclusive access and in The Anglophone Chile Project newspaper archive residing in the Universidad Adolfo Ibanez, which is collaborating with the project. (Prain, 2010)
Later iterations of the interactive site will feature the whole of Latin America, where Everton clubs proliferated and migrant communities celebrated their identity through football clubs such as the Italian ‘Gringos’ in Coronel Moldes, British railway workers in Cruz Alta, Cañada de Gómez and various communities in La Plata, Argentina and Rosario, Uruguay.
Drawing upon Latin America\u27s tradition of magical realism, the interactive documentary will incorporate XR content and feature narration from different historical perspectives, including those of the Mapucha, early mining communities, railway labourers, wealthy European merchants and Everton’s inspiring tour of the continent in 1909.
This is a case study; an approach which can be applied to other sports and regions of the world. Whilst storytelling is at it\u27s core, the documentary will encourage empathy, awareness of local issues, culture and history and inspire conversation; building more inclusive local, national and transnational communities. Interactivity will empower diverse participatory audiences to upload their own stories and personal reflections, building a unique resource of social history, lived experience and enhanced cultural understanding.  
Media and Architecture: How Cityscapes and Built Environment are Defined by Cinema in India in the New Millennium
No full textThis paper proposes to study the influence of cinema and media on the built environment in contemporary India. Following the reorganisation of the states since the new millennium there has been a demand to build cities, either as ‘new’ capital cities for the bifurcated states or as globally inflected cities for trade, commerce, and employment. This city-making effort, often environmentally unsustainable, has developed peculiar and unique association with cinema and the new media. This can be witnessed in the example of the proposed capital city of Amaravati for the Telugu-language state of Andhra Pradesh, after its separation from Telangana. The then Chief Minister of the state, Mr. Nara Chandra Babu Naidu (CBN) in 2017, inducted a well-known Telugu film director, S.S. Rajamouli (SSR), as the government’s representative to advise architects, Norman Foster + Partners.
SSR who was enjoying the success of Baahubali, a two-part fantasy Telugu film across India, had begun to develop a pan-India base for his films. SSR’s rendition of a fiction city, ‘Mahishmati’ in Bahubali had reportedly brought him on-board to envision a real city for his people in its real time and space. The larger-than-life visuals of the fictional city and the grandeur of the sets of Bahubali took the country by storm, making the film the largest grossing film of the times.
The revised designs emerged as a confluence of the global architectural trends and a contrived notion of the cultural symbolism of the region. Despite all these efforts, Naidu failed to impress the public. His eventual defeat in the following elections left Amaravati in a state of limbo, of perennial uncertainty. The purposed paper examines these links-- the significance of image-based aesthetics inspired by cinema that dictate the planning and development of cities, and the eventual deadlock towards sustainable cities in contemporary society
