Calculating How Many Particles Are Released Into the Environment When Car Brake Pads Are Worn
No full textThis article describes the procedures for calculating the quantity of particles discharged into the atmosphere due to brake lining deterioration during vehicle braking, accounting for the wheel\u27s adhesion coefficient to the road. The quantity of particles that automobiles release into the atmosphere was determined theoretically, taking into consideration the fact that the resource period of brake pads varies based on the adhesion coefficient of the wheel with the road. Analysis of the metal concentration distribution in the particles created by brake lining wear during vehicle braking is extensively discussed. It was discovered that the car\u27s brake samples included high concentrations of metal components such iron, copper, zinc, chromium, tin, and antimony. There is already information available regarding the harm that automobile brake particulates cause to the environment. A comparative examination of theoretic and experimental findings on the brake lining wear rate in relation to the road adhesion coefficient is showcased. The average wear speed of car brake pads varies depending on the adhesion coefficient of the road; this variation in wear speed has been proven by a comparative comparison of the theoretical calculation results
The Method of Improving Fuel Efficiency Indicators and Ensuring Environmental Safety of Gas Cylinder Vehicles in Low Temperature Weather Conditions
No full textThe number of vehicles is increasing, and the energy resources needed for them are lacking. Also, the use of
petroleum fuels in vehicles causes their negative impact on the environment to increase. The use of energy-efficient
technologies and environmentally safe alternative fuels in the operation of vehicles is currently considered to be very
important. Also, technological adjustment of vehicles for different climatic conditions is one of the effective solutions to
ensure fuel economy and environmental safety.
The scientific paper analyzes the methods of minimizing petrol consumption in low-temperature operating conditions
of gas cylinder vehicles (GCV) with a universal fuel supply system running on compressed natural gas (CNG) fuel in order
to ensure the operational efficiency and environmental safety of vehicles. Recommendations for saving fuel consumption
and ensuring environmental safety of GBA in low-temperature operating conditions have also been developed

System Analysis of Space Imagery Processing Methods
No full textFor educational purposes, it is very important to apply new methods, technologies and break down each stage of processing into a common cross-industry activity and further by their types of activity. To quickly master the processing in one instance, for example, when entering the analysis, narrow specialists require ready-made materials for preliminary pre-processing. If in the process of work there is a discrepancy between the results and the set goals, then the material significance of the processing can be guaranteed to achieve the results, which can reduce the pace of the study. One of the advantages of a narrow specialization is the formulation of the problem of a database from data, that is, the verification of preparation, data from space, cartographers and materials obtained from terrestrial measurements. The learning process begins with the choice of processing methods that happen and apply to use special methods, it is very important to know the choice of image, which satellite and how to create a complete material from raw data for automatic interpretation.
The scientific paper presents an overview and analysis of satellite data processing methods. Existing satellite data processing methods do not describe the model of user interaction with a computer system, where the user can independently set the processing parameters (algorithms and their parameters). Such interaction is in demand by users and is associated with the selection of algorithms and their specified parameters to obtain the final result

Queering as Process: Disrupting Scientific Imperialism for Health Justice Using Kitchen Table Pedagogy
No full textThis article is a composite narrative case study exploring my experience of facilitating workshops around food and eating with participants who have a conflicted relationship with food or are confused by nutrition messages. Many of the workshops have been with queer, especially trans and gender-expansive, participants. I use a Freirean, interactive, story-based teaching style that I call ‘kitchen table pedagogy’.
An aim is to investigate any role that thinking beyond the binary - or queering as process - may have in helping us relate to food and our bodies in new ways that are more conducive to personal flourishing as entangled with collective liberation and hence climate justice. I illustrate how a liberatory pedagogy and queer praxis address the root of oppression by considering the provocation “How does public health nutrition perpetuate a racist, capitalist cisheteropatriarchal world view as normal, desirable, inevitable and how can queer(ing) food narratives interrupt this drive and replace it with something liberatory and life-affirming?
Training Dietitians to Champion LGBTQ+ Health: An Appreciative Inquiry of Dietetic Education in the UK
No full textHealth inequalities experienced by LGBTQ+ people motivate a call for the queering of dietetics, through an embodiment of queer pedagogies in dietetic training. A critical review of LGBTQ+ inclusion strategies identified a paucity of focused pedagogic research, limiting the queering of dietetic training programs. This study appraised such teaching practices in the UK through a positive focus on “what works?”. An interview study was undertaken with 14 participants who were dietitians, dietetics lecturers, or current dietetics students, all identifying as LGBTQ+ people. Semi-structured interviews generated qualitative data on LGBTQ+ journeys through dietetic training and into practice. An appreciative inquiry approach was used to develop a solutions-focused template analysis to appraise innovative, imagined, and inspired practices in the queering of dietetic training in the UK. Thematic outputs were informed by appreciative inquiry’s positive modalities of change, illustrating diverse perspectives on the definition of cis-heteronormativity in dietetics, and the discovery, dreaming, design, and deployment of queering practices to support their disruption. The analysis generated complex multi-stakeholder actions to bring about the queering of dietetic training, and appraising current educational practices in universities, clinical placement, and other learning environments. The study revealed opportunities for the queering of dietetic training, exposing spaces of educational queering far beyond the classroom. For the queering of dietetic training, we present recommendations concerning the development of LGBTQ+ inclusive curricula, teaching practices, and wider professional strategy through the dietetics governing bodies. Further studies should expand appreciative exploration of the queering of dietetic training to allies and LGBTQ+ patients
