Published: May 2024

The shift towards sustainable transportation is an urgent worldwide issue, leading to the investigation of creative methods to decrease the environmental effects of traditional vehicles. Electric vehicles (EVs) are a promising alternative, but the issue lies in establishing efficient and environmentally friendly charging infrastructure. This review explores the existing research on the subject of photovoltaic-powered electric vehicle charging stations (EVCSs). Our analysis highlights the potential for economic growth and the creation of robust and decentralized energy systems by increasing the number of EVCSs. This review summarizes the current knowledge in this field and highlights the key factors driving efforts to expand the use of PV-powered EVCSs. The findings indicate that MATLAB was predominantly used for theoretical studies, with projects focusing on shading parking lots. The energy usage varied from 0.139 to 0.295 kWh/km, while the cost of energy ranged from USD 0.0032 to 0.5645 per kWh for an on-grid system. The payback period (PBP) values are suitable for this application. The average PBP was demonstrated to range from 1 to 15 years. The findings from this assessment can guide policymakers, researchers, and industry stakeholders in shaping future advancements toward a cleaner and more sustainable transportation system.

Published: May 2024

The article entitled The Influence of Socio-Cultural Aspects on Village-Owned Enterprises (BUMDes) Maju Bersama Wolotolo Village, Ende Regency, East Nusa Tenggara aims to examine the influence of social and cultural aspects in the formation, participation or selection of business units, as well as the recruitment of BUMDes members between 2016-2017.The focus of this research is to see how customs, traditions and cultural values become the basis and influence the formation process of BUMDes. This research utilizes Structural Functionalism and Social Capital theories. A qualitative approach is used in this research to collect and analyze data. Data were collected through interviews, observation and documentation. Based on the research, it was concluded that the traditions and customs of the local community influenced the pattern of cooperation based on the tradition of gathering together in the village, the recruitment of administrators who were influenced by customs based on closeness and kinship factors, and the pattern of work that was strongly influenced by the development of local community habits to be very fund-oriented. This then brings positive impacts such as loyalty, but on the other hand there are also many negative impacts such as the low professionalism, skills and capacity of the management, the exclusion of other parties from the management of the BUMDes, as well as making a work pattern that always sees the availability of funds as a benchmark for organizing activities so that all of that leads to the stagnation of business activities in the BUMDes.

This article aims to see how metacommunication in the phenomenon of online begging on TikTok social media. TikTok is one of the social media that is currently popular. Like other social media, TikTok should be used to interact virtually between one person and another. Researchers found the phenomenon of changes in meaning in the use of TikTok social media by several individuals. Some of the people in question use TikTok to beg online. This of course makes the meaning of social media change meaning. The problem is focused on the metacommunication that occurs on TikTok social media, which is currently found in many online begging phenomena. The method used in this research is descriptive qualitative using literature studies from several journals. This study concludes that metacommunication has occurred on TikTok social media where TikTok, which is known as a social media for interacting in cyberspace, has changed its meaning to become a place to carry out begging activities. The things that online begging actors do are dancing, sleeping in the garden and even taking a mud bath if someone gives a gift with various characters as a form of digital substitute for money with different amounts. Researchers also found that the mention of online begging activities with "Challenge Merchants" or "Non-Playable Character live streaming".

Published: May 2024

Key Points

Psychotropic medication use is prevalent in the pediatric CKD population.

Central nervous system stimulant usage was more common in male patients, and antidepressant usage was more frequently reported at follow-up visits during teenage years.

Background

Mental health disorders within the pediatric CKD population are prevalent. The frequency is unknown with which psychotropic medications that commonly treat these conditions are used in this population.

Methods

Data from the CKD in Children (CKiD) cohort study were used to describe the use of psychotropic medications and patient-related characteristics of use. Medications were classified into three groups: antidepressants, central nervous system (CNS) stimulants, and antipsychotic/mood stabilizing medications. Participant age, sex, CKD severity, and duration of medication use were ascertained. Medication use was evaluated in parallel with CKD disease type, presence of urological comorbidity, and hypertension. Chi-square tests compared subgroup medication use.

Results

Among 1074 CKiD participants (median baseline age 9.8 years), 6% (n=60) used psychotropic medications at study entry with 11% reporting incident use of any medication category (n=120). CNS stimulants were most common at baseline. Antidepressants were more frequent among incident users at 7%. Use of two or more medications was rare (3%). Median eGFR at medication initiation was 45 ml/min per 1.73 m2. CNS stimulants were reported at a higher rate in male compared with female participants (P < 0.05).

Conclusions

Eleven percent of CKiD patients report incident use of any psychotropic medication, with 7% reporting incident use of antidepressants. Future work is warranted to better ascertain the frequency, safety, and efficacy of psychotropic medication usage in relationship to formal mental health disorder diagnoses in the pediatric CKD population.
Predicting Foliar Nutrient Concentrations across Geologic Materials and Tree Genera in the Northeastern United States Using Spectral Reflectance and Partial Least Squares Regression Models
Authors: Teng Wenxiu , Yu Qian , Mischenko Ivan C. , Rice Alexandrea M. , Richardson Justin B.
Published: May 2024

Spectral data can potentially offer a rapid assessment of nutrients in leaves and reveal information about the geologic history of the soil. This study evaluated the capability of the partial least squares regression (PLSR) for estimating foliar macro- and micronutrients (Ca, Mg, K, P, Mn, and Zn) using spectral data (400 to 2,450 nm). First, filter-based wavelength selection was conducted to reduce the independent variables. PLSR performance was then assessed across 4 geologic materials (coarse glacial till, glaciofluvial, melt-out till, and outwash) and 4 dominant tree genera (
Acer
,
Betula
,
Fagus
, and
Quercus
) in the northeastern United States. The spectral ranges 400 to 500 nm and 1,800 to 2,450 nm were found to be the most important spectral regions for estimating foliar nutrient concentrations. The developed PLSR model predicted 6 foliar nutrients with moderate to high accuracy (adjusted
R
2
from 0.60 to 0.75). Foliar macronutrient concentrations were estimated with higher accuracy (mean adj.
R
2
= 0.69) than micronutrient concentrations (mean adj.
R
2
= 0.635). The prediction for the individual tree genera group and the individual geologic materials group outperformed the combined group; for instance, the adj.
R
2
for estimating Ca and P was 39% higher for American beech (
Fagus grandifolia
) than all tree genera combined. Spectral measurements combined with wavelength selection and PLSR models can potentially be used to quantify foliar macro- and micronutrients at regional scales, and taking into account geologic materials and tree genera will improve this prediction.
A Scalable, High-Efficiency, Low-Energy-Spread Laser Wakefield Accelerator Using a Tri-Plateau Plasma Channel
Authors: Liu Shuang , Li Fei , Zhou Shiyu , Hua Jianfei , Mori Warren B. , Joshi Chan , Lu Wei
Published: May 2024

The emergence of multi-petawatt laser facilities is expected to push forward the maximum energy gain that can be achieved in a single stage of a laser wakefield acceleration (LWFA) to tens of giga-electron volts, which begs the question—is it likely to impact particle physics by providing a truly compact particle collider? Colliders have very stringent requirements on beam energy, acceleration efficiency, and beam quality. In this article, we propose an LWFA scheme that can for the first time simultaneously achieve hitherto unrealized acceleration efficiency from the laser to the electron beam of >20% and a sub-1% energy spread using a stepwise plasma structure and a nonlinearly chirped laser pulse. Three-dimensional high-fidelity simulations show that the nonlinear chirp can effectively mitigate the laser waveform distortion and lengthen the acceleration distance. This, combined with an interstage rephasing process in the stepwise plasma, can triple the beam energy gain compared to that in a uniform plasma for a fixed laser energy, thereby dramatically increasing the efficiency. A dynamic beam loading effect can almost perfectly cancel the energy chirp that arises during the acceleration, leading to the sub-percent energy spread. This scheme is highly scalable and can be applied to petawatt LWFA scenarios. Scaling laws are obtained, which suggest that electron beams with parameters relevant for a Higgs factory could be reached with the proposed high-efficiency, low-energy-spread scheme.
Brain Short-Chain Fatty Acids Induce ACSS2 to Ameliorate Depressive-Like Behavior via PPARγ–TPH2 Axis

Published: May 2024

Short-chain fatty acids (SCFAs) have been increasingly evidenced to be important bioactive metabolites of the gut microbiota and transducers in controlling diverse psychiatric or neurological disorders via the microbiota–gut–brain axis. However, the precise mechanism by which brain SCFAs extert multiple beneficial effects is not completely understood. Our previous research has demonstrated that the acetyl-coenzyme A synthetase short-chain family member 2 (ACSS2) is a novel target of the rapid and long-lasting antidepressant responses. Here, we show that micromolar SCFAs significantly augment both total cellular and nuclear ACSS2 to trigger tryptophan hydroxylase 2 (TPH2) promoter histone acetylation and its transcription in SH-SY5Y cells. In chronic-restraint-stress-induced depression mice, neuronal ACSS2 knockdown by stereotaxic injection of adeno-associated virus in the hippocampus abolished SCFA-mediated improvements in depressive-like behaviors of mice, supporting that ACSS2 is required for SCFA-mediated antidepressant responses. Mechanistically, the peroxisome-proliferator-activated receptor gamma (PPARγ) is identified as a novel partner of ACSS2 to activate TPH2 transcription. Importantly, PPARγ is also responsible for SCFA-mediated antidepressant-like effects via ACSS2–TPH2 axis. To further support brain SCFAs as a therapeutic target for antidepressant effects,
d
-mannose, which is a naturally present hexose, can significantly reverse the dysbiosis of gut microbiota in the chronic-restraint-stress-exposure mice and augment brain SCFAs to protect against the depressive-like behaviors via ACSS2–PPARγ–TPH2 axis. In summary, brain SCFAs can activate ACSS2–PPARγ–TPH2 axis to play the antidepressive-like effects, and
d
-mannose is suggested to be an inducer of brain SCFAs in resisting depression.

Severing Ties: A Pedagogy for Envisioning New Typologies of Environmentally-Attuned Architecture
Authors:   Rensselaer Polytechnic Institute, Bennett Christianna
Published: May 2024

The relationship between architecture and landscape must undergo fundamental change to deal with the urgency of the climate crisis, adapt to changing cultural values, and support local environmental conditions. Although there has been progress in modifying architectural construction methods and implementing the use of sustainable materials, structures continue to depend on extractive infrastructure through integrated building systems such as electricity, telecom, heating, and cooling. The ongoing reliance on extractive infrastructure bonds architecture to exploitative technologies and industries, which has fundamentally altered its relation to landscape. At present, architecture relies on an abundance of fuel from distant locations to operate, and ignores its surroundings as a result.In recent design studios, I ask students to generate alternate connections between architecture and environment. Specifically, I teach students how to critically disengage from extractive processes and systems, and instead knit architecture into local ecosystems. This is achieved through critical analysis of existing infrastructure and the design of new systems. Supported by the integration of interdisciplinary perspectives, the rewiring of systems results in new, speculative architectural typologies that engage reciprocally with complex ecologies. According to this framework, students interrogate the role architecture plays in the sustenance of the environment and are challenged to design in ways that depart from the status quo. Lessons include a) direct observation and interpretation of nature, b) translation of observations and interpretation into systems-focused interventions, c) an integrative approach linking systems and objects, and d) exercises in ‘making worlds’ and ‘futuring,’ for forming speculative narratives about architecture’s future role in the environment. By addressing these issues, architecture becomes an instrument for reimagining human relationships with nature and serves as the basis for forming new bonds with the environment.
Geothermal Cultures in Para-Climate Change Iceland
Authors:   Rhode Island School of Design, Chen Debbie
Published: May 2024

The road to decarbonization is a web of woven pathways – while the building sector works hard to reduce embodied andoperational carbon, governments and utilities should pivot cities away from fossil fuels and incentivize renewable energyinfrastructure. On this latter point, architectural design could play an important role on how renewable energy is adoptedinto the everyday life of its users. Beyond energy models and smart envelopes, design has an under-appreciated influenceon how cultural value is perceived or produced through any given built infrastructure or utility. Furthermore, constructinga larger cultural framework around renewable energy systems helps to accelerate and substantiate the green transition. Inquestioning how architecture participates in this cultural rethinking, this paper focuses on Iceland integration of geothermal energy into everyday cultural practices and how architectural effects work in tandem to produce this cultural-infrastructural bind.Iceland’s survival through anthropogenic change is both age-old and ever-present. Volcanic eruptions and high ratesof soil erosion provide scarce arable land, yet geothermal and hydroelectric power sustain the country with 85% renewableenergy. Simultaneously bountiful and limited in resources, Iceland’s integration of geothermal energy into multiple cultural spheres is a harbinger for a built environment practicing climate adaptation and survival. The research, conducted in Summer 2023, involves the documentation of geothermal sites (active geothermal fields, energy generation facilities, greenhouses, heritage sites, food vendors, etc.) and the analysis of material, formal, haptic, and tectonic qualities attached to these systems. As an ongoing project, Geothermal Cultures will continue to focus on how renewable energy systems, cultural practices, and architectural form work together to encourage public support towards renewable infrastructure.
Places & Plants: Exploring Weeds And Other Self-Seeded Plants As Architectural Forensics
Authors:   University of Arizona College of Architecture, Planning, and Landscape Architecture, Despland-Lichtert Noémie
Published: May 2024

While much of contemporary architectural discourse around plants tends to focus on their aesthetic aspects, origins, and potential uses—such as to provide ornament, drought- resistance and/or cooling, etc.—self-seeded plants, weeds and other undesirables tend to be less of a direct subject of interest and object of study within the discipline.This paper proposes an alternative relationship between architecture and plants, in which urban and self-seeded flora are used as forensic material and studied as evidence of urban change, spatial politics and movements of people, ideas, and construction materials. For example, it looks at seeds traveling with construction materials, or under trains, as well as plants resurfacing as a consequence of bulldozed or demolished sites. The research argues that plants, rather than simply a soft landscape material counterpoint to the concrete reality of building, can be used to study the resilience of landscapes and uncover site-specific histories. Specifically, the paper introduces a series of case studies by describing participatory workshops hosted in Canada, the United States, and Germany developing a methodology for fieldwork, community engagement, and oral history through carefully investigating a chosen site and its weeds. The methodology also serves to question the so-called“vacant” and “abandoned” nature of the chosen site within the larger context & discourse about public revitalization and other gentrification endeavors. By reframing weeds as valid and worthy of interest, this paper contests the devitalized or under-vitalized nature of chosen sites by opening conversations around social, public, and environmental interactions at large. Ultimately, this presentation also explores a range of discursive models to complexify revitalization discourse, articulating a nascent model for public engagement with architecture and site-specific histories through urban botany.
Trans-scalar Architectures for Earth: Rain Check
Authors:   University of Colorado Denver, Ibarra José
Published: May 2024

Water is a precious and contested resource in Colorado, the seventh driest state in the United States. Throughout its geologic history, this territory has seen innumerable configurations spearheaded mostly by uplifting and erosion. During its human history, the land has also seen several important infrastructural and other changes, especially as they relate to water usage. Responding to these conditions, this pedagogical exercise recontextualized “nature” by designing for and with geological systems. The studio combined models of design-build pedagogy, paired with a continuous focus onmulti-scalar relationships, water-power relations, and speculative thinking. Students developed a prototypical pavilion made to treat water, host a number of plant ecosystems, and engage human publics by educating them about water and interspecies collaborations.Through a combination of surrealist methodologies, environmental simulations, materials assessments, applied design/research work, and reading discussions, the class responded to the pre-existing site and climatic conditions much like asurrealist artist would respond to pre-drawn lines on a page. This allowed us to reimagine forms of authorship for architecture in the Anthropocene, welcoming new agents to the design of our shared planet while engaging the extreme dryness and desertness of our environment. Ultimately, the project aims to render the Colorado water and environmental crises visible through a public space-defining installation that can remediate ecosystems.
Sage Hill : A Post-Natural Geoform for Multi-Species Restoration

Published: May 2024

As humans continue to develop, build, and rebuild on areas around the globe, the integrity of the soils that are built on continue to be compromised through this distribution and environmental conditions. With the accelerating damage and effects of climate change, the technologies employed in environmental engineering are expected to provide protection, as well as an ecologically sensitive application. The clearing and replacement of existing landscape is inherently human centric, as it disregards the other cyclical relationship at play between the vertical elements of a root stabilizing tree stands and their surrounding biodiversity. Joyce Hwang in her essay, Living Among Pests, has suggested that the needed reconnection of biodiversity with our urban buildings will force a re-examination of “articulation [of our built surfaces] to take on more responsibilities. Ornament will become performative.1” The project, Sage Hill, re-imagined the practice of soil-stabilized geotextiles, through new material and technical investigations towards a post-natural condition. A small hill was designed and composed of a series of 3d printed earthenware geo-textiles that wove together, informing a topo-graphic chain, providing both soil stabilization as well as habitat establishment for both flora and fauna.

Adaptive reuse is the process of renovating old buildings for new use. It is often seen as a more sustainable option than demolition and new construction, as it can help to reduce waste and conserve resources. However, there has been limited research on the environmental benefits of adaptive reuse from a life cycle perspective. This study aims to provide empirical evidence of the environmental benefits of adaptive reuse by conducting a life cycle analysis (LCA) of a three-story historical building in Zabrze, Poland. The LCA compared the environmental impacts of the historical building to those of a proposed adaptive reuse project. Five impact categories were assessed: global warming potential, ozone depletion potential, acidification potential, eutrophication potential, and smog formation potential. The results showed that adaptive reuse was effective in avoiding environmental impacts across most impact categories. Global warming potential demonstrated the highest avoided impact (82%), followed by smog formation potential (51%), acidification potential (27%), and eutrophication potential (21%). These findings provide quantifiable evidence of the environmental benefits of adaptive reuse and emphasize focusing on the adoption of adaptive reuse as an effective way to reduce carbon emissions and mitigate environmental impacts from the built environment.
Obesidad

Published: May 2024

Difícil resulta pretender dar una definición original a la vez que científica del síndrome obesidad. Decir que es el aumento exagerado de peso de un sujeto con relación a su estatura, es dar una idea clara y gráfica de lo que representa la obesidad desde un punto de vista estético y patológico, pero no científico. Encarado el síndrome desde alguna de sus diferentes partes constitutivas (Etiopatogenia, sintomatología o formas clínicas) la dificultad se atenúa, pero el objetivo se diluye. Armonizando estos diferentes factores, podemos decir que la obesidad es una perturbación del metabolismo, caracterizado por la tendencia anormal a la acumulación de la grasa en todo o parte del cuerpo y que trae por consecuencia una disminución de la capacidad funcional del organismo. Esta acumulación exagerada de la grasa rompe si la relación entre peso y estatura; pero hasta que límite se puede llevar esta relación sin que el individuo pueda ser catalogado de obeso?. La gordura es el síntoma más ostensible del síndrome, pero ya veremos bajo que condiciones. No basta aplicar la fórmula de Broca o de Von Noordon o la de Bornhardt, para hacer un diagnóstico de obesidad. Ya los pueblos de la historia antigua, Egipcios, Griegos y Romanos hablaban de obesidad, pero bajo un concepto simplista de estética» Hoy hablamos de obesidad diciendo que es una hiperlipofilia tisular de naturaleza constitucional, cuya distribución en el cuerpo está regulada por el sistema neuro-endódrino.

La hidronefrosis no es una enfermedad ni una afección mórbida, es una lesión anatómica determinada por otras lesiones o condiciones anatómicas.
Las competencias socioemocionales de los docentes y su rol en el aula
Authors: Muñoz Dilsa
Published: May 2024

The main objective of this article was to determine the socioemotional skills of teachers in a school in Colombia. These skills allow for self-recognition and recognition of others, as well as acceptance and assertive action in response to feelings. The school, as a space for encounter, interaction, and continuous learning, becomes a conducive environment for the proper emotional management of both students and teachers, with the latter being fundamental pillars. In this study, we present research conducted with 40 teachers from an educational institution. Participants completed the TMMS-24, Trait Meta-Mood Scale on Emotional States, which provided a quantitative approach for data collection. The main aim was to analyze how this group of teachers manages emotions and, furthermore, to use these results as an opportunity to raise awareness among teachers about the importance of being aware of their own emotions and those of their students in the day-to-day classroom dynamics and relationships established within it. Findings revealed that the majority of teachers demonstrate adequate emotional management, as evidenced by the three dimensions investigated in the questionnaires, indicating that most are at an appropriate level of recognition, comprehension, and management of emotions. This translates into better job performance, higher levels of satisfaction among teachers, and a better understanding of the individual situations of each student.

The service life of heavily loaded shafts is largely determined by the degree of stress in the transition area from one diameter to another. There are a fairly large number of methods for reducing the stress concentration of these areas, but a special place in this case is occupied by strengthening the surfaces of non-profile, heavily loaded shafts. First of all, their fillets are subjected to hardening, which leads to the formation of uniformly distributed compressive stresses in the technological zone and, accordingly, an increase in the fatigue strength of such parts. The method has become especially widespread when hardening crankshafts. Along with this, surface hardening is applied to the abovementioned part to eliminate its bending. This technological process is especially important in the case of restoration of rotating parts. Meanwhile, existing work in this area does not solve existing issues. In this regard, it is necessary to give a critical analysis of the methods and designs for PPD fillets with the development of appropriate proposals, which determines the relevance of the work. The purpose of the study is to consider devices and methods for strengthening fillets of bodies of rotation of PPD, their classification and development of recommendations for improvement. To reveal the goal, the authors conducted a comprehensive review of the information available in the public domain regarding the strengthening of fillets by cold hardening. This made it possible to identify their advantages and disadvantages. First of all, this is the lack of a unified classification system, as well as methods for preventing the formation of a “wave of deformation”. Based on the analysis, a classification is proposed based on the factors that determine the properties of the shafts and the quality of their surface layers and the functional purpose of the processing. A proprietary scheme for processing SPD surfaces is proposed, which ensures the prevention of a “wave of deformation” in one pass of the working tool, which is based on the well-known principles of the theory of the introduction of a ball indenter into a solid.

Research on the effect of ozone treatment on metal corrosion is presented in the article. The results of experiments on changes in the state of metals and steels when they are in aggressive environments in the presence of ozone are analyzed. In most cases, the ozone-air mixture has a negative effect on various metals and welded joints, increasing the rate of corrosion. Considering that recently the popularity of ozone technologies in all industries has been steadily growing, the massive use of ozone in agriculture is a matter of time. Therefore, there is a need to conduct research aimed at studying the corrosion resistance of various steels and alloys used in the agricultural sector. It has been analytically established that one of the most accessible alloying elements resistant to ozone treatment is chromium. However, its content in steel grades Steel 08kp, Steel 45, 45X, Steel 60S2, which are most widely used in agricultural engineering, ranges from 0.1 to 1.1%. This chromium content may be insufficient and therefore similar studies need to be carried out. It was established that the most common Steel 08kp showed sufficient resistance to aggressive environments in the presence of ozone as a result of the experiment, quite comparable with more expensive alloys. At the same time, the introduction of ozone into a solution of 70% acetic acid reduced the weight loss per unit area of steel grades Steel 08kp, Steel 45, 45X, Steel 60S2 by 2...7 times. This suggests that ozone blocks metal atoms and prevents exposure to aggressive environments.

Mixers with technical characteristics established by GOST 20680-2002 are not suitable for mixing solutions of polymer nanocomposites when restoring bearing fits. The optimal design parameters of a multi-bladed turbine mixer with full-length inclined blades for mixing solutions of polymer nanocomposites were determined at the Lipetsk State Technical University. Formulas for calculating the pumping effect and power when designing multi-blade turbine mixers of various sizes are obtained using these parameters. The average value of the peripheral speed coefficient, which is k≈0.92, was determined experimentally. A formula for calculating power when designing multi-blade turbine mixers of various standard sizes with full-length inclined blades is proposed. The experiment showed a high convergence of calculated and actual values of power consumed by a turbine mixer when mixing nanocomposite solutions. An experiment was carried out to evaluate and select a similarity criterion for the design of multi-bladed turbine mixers of various standard sizes. Reynolds and Froude similarity criteria were studied. The light transmission coefficient of the solution after stirring at a rotation frequency determined by the Reynolds criterion is Kc=57%. A similar parameter of the solution after treatment in the mode determined by the Froude criterion is 2.2 times lower and amounts to Kc = 26%. A higher quality index according to the Froude criterion is confirmed by the fact that the strength of the samples is σ = 27.308 MPa, which is 1.24 times greater than the strength of samples obtained from nanocomposite solutions processed in the mode determined by the Reynolds criterion. A formula for calculating the power of multi-bladed turbine mixers with inclined blades was proposed as a result of the research. Modeling of the design and operating parameters of multi-blade turbine mixers of various standard sizes should be carried out according to the Froude criterion.

Research of the interrelationships between the time periods of stabilization of the technological process of trier grain cleaning from: feeding the grain mixture into the trier; its initial contamination; speed mode of operation and angular position of the output tray relative to the horizon are satisfied. They were carried out using experimental equipment that provided separate, regulated and continuous supply of grain mixture components into the trier with a looped movement of purified grain. Standard methods and instruments, as well as special instruments developed at the Federal State Budgetary Institution VNIITiN, were used to assess the physical and mechanical properties of the components of the grain mixture. It was found that with a supply of 1.2 t/h, an initial contamination of 1.3% and a lifting angle of the output tray of 55°, the speed mode of operation of 36.0 rpm is excessive, while stabilization of the process is not completed even after 15 minutes (92% ), the length of the free section of the cellular surface is 0.70 - 0.75 m, which increases the level of residual grain contamination to 0.025 - 0.04%, which does not meet the requirements for seeds of the OS category. The possibility of reducing the comparable level of process stabilization by 6 times when the operating speed is reduced to 34.6 rpm (by 3.9%) has been confirmed. Reducing the operating speed to 34.0 rpm leads to an increase in process losses to 16.85%. It has been established that with an increase in the initial contamination of the grain mixture to 2.6%, the stabilization period of the process at a speed mode of 34.6 rpm increases from 4.5 to 5.5 minutes, and technological losses reach the maximum permissible value (5%). The method for calculating the actual degree of stabilization of the process with its assessment based on the removal of impurities has been refined.

Issues of increasing the reliability of working parts of agricultural machines interacting with the soil surface are discussed in the article. A loading model based on taking into account microroughness of the surface soil layer using a fractal surface model constructed using the diamondsquare algorithm is proposed. It is shown that the parameters of microroughness of the soil surface, calculated using the proposed model, correspond to experimental data obtained by profiling the soil surface during pre-sowing treatment and during the preparation of flax. A comparative calculation of the loading of the needle harrow tooth and the tiller tooth was carried out in accordance with the model of a flat soil surface and a soil surface with a microrelief, modeled according to the proposed model. It is shown that the mechanical stresses in the working bodies interacting with the soil surface, loaded according to the proposed model, are 14% greater during pre-sowing treatment, and 25% greater when preparing flax trust, than when calculated using a model of a flat soil surface. The use of a microrelief model is optimal both when calculating soil tillage machines and when calculating other flax harvesting machines (pulling machines, flax sliver fluffers, balers and other units) that are not intended for direct tillage of the soil, but have contact with it during the technological process.
