Memória e testemunho em livros jornalísticos
Authors: Maia Marta Regina , Fernandes José Carlos
Published: September 2023

As novas alterações no campo jornalístico proporcionaram a ampliação das produções autorais dos jornalistas a partir das produções em livros, como foi o caso dos jornalistas Zuenir Ventura e Teresa Urban que fizeram dos acontecimentos de 1968, no Brasil, uma plataforma para conciliar, na narrativa, elementos como memória e testemunho. Em seus livros – ela numa articulação entre quadrinhos e a colagem; ele em uma reportagem, com flerte da crônica na divisa do depoimento – acabaram por produzir dois documentos “vivos” que representam o jornalismo de fronteira, em que informação, história e literatura formam um conjunto que desafia a rigidez da linguagem jornalística. Temos como objetivo, portanto, fazer uma análise da narrativa dos livros 1968 – O ano que não terminou e 1968 ditadura abaixo a partir de dois operadores metodológicos, que são a memória e o testemunho. Os livros permitem aproximações entre os operadores, mostrando como é possível aliar experiência, história e relatos em uma perspectiva fronteiriça da linguagem que se direciona ao jornalismo narrativo.
Práticas de Representação: uma Cartografia de Experimentações na Cultura Midiática
Authors: Carvalho Nilton Faria de
Published: September 2023

Os sentidos produzidos nas representações midiáticas atravessam os territórios simbólicos e imaginários. O cenário atual, de autoritarismos, precariedade do trabalho e pós-verdade, é preciso retomar práticas mais plurais e a representação midiática é arena importante. Busca-se neste texto uma reconfiguração de perspectivas representacionais capaz de dar respostas ao nosso tempo. Pensando a cultura das mídias como semiosfera (LOTMAN, 1996), locus de semioses diversas, a base conceitual e teórica parte de Stuart Hall (2003) e seu entendimento sobre as práticas de representação nas mídias para, em seguida, propor o deslocamento de grandes pressupostos rumo a um ato de pensar criativo frente aos signos (DELEUZE, 2006) e propõe experimentos de linguagem, nos termos Giorgio Agamben (2017), para reposicionar a representação em novas bases éticas e políticas. Pelo método cartográfico aplicado à comunicação, este trabalho identifica um corpus inicial que passa por dois eixos: jornalismo e cultura pop.
Entre o objetivo e o subjetivo: a presença de novos valores-notícia no jornalismo esportivo
Authors: Leal Daniel , Mesquita Giovana
Published: September 2023

O jornalismo esportivo comporta-se com atrevimento capaz de desafiar determinadas regras basilares da profissão para se tornar uma espécie de laboratório de experimentação, explorando novos caminhos narrativos e formatos (TORRIJOS, 2022). Neste sentido, este artigo propõe uma revisão bibliográfica para abordar alguns dos conceitos relativos à noticiabilidade, ao valor-notícia e à seleção noticiosa, especialmente a partir da visão de Nelson Traquina e Mauro Wolf, para realizar uma correlação de como essas classificações dialogam com o jornalismo esportivo. Observamos que este campo é capaz de ressignificar determinados valores e fazer aparecer outros, sendo um fértil produtor de debates que dialogam com o objetivo e o subjetivo. Além disso, este trabalho também propõe novos valores-notícia surgidos, essencialmente, por via das mudanças sociais, do impacto da audiência potente (MESQUITA, 2022) e da evolução tecnológica.

Authors: Fritz Susan , Barbuto John E. , Marx David , Etling Arlen , Burrow Shawn
Published: September 2023

This study explored motives and identified strategies for service recognition of a sample (714) of Nebraska 4-H organizational andproject volunteer leaders. On average, volunteers sampled were 43 years of age, parents of children in 4-H, and had been involved as a 4-H member more than 7 years. Respondents were predominately motivated by affiliation, and, therefore, identified most strongly with volunteering because of a desire to help others, associate with youth, and to be with their children involved in 4-H. Volunteers preferred to be recognizedfor their service by 4-H members in various forms. No relationship was established between motives to volunteer and preferred forms of recognition.
A QUALITATIVE STUDY OF URBAN AND SUBURBAN ELEMENTARY STUDENT UNDERSTANDINGS OF PEST-RELATED SCIENCE AND AGRICULTURAL EDUCATION BENCHMARKS
Authors: Trexler Cary J.
Published: September 2023

The purpose of this qualitative study was to determine the understandings of pest-related science by elementary students f (N = 9). Guided by theoretical frameworks for science education and studies on agricultural literacy, clinical interviews were used to surface fifth graders thinking about three benchmarks for the concept of human management of crop growth. Data analysis included validating benchmarks and language to guide the discourse, generating conceptual proposition maps, coding student responses for comparison with expert propositions, and confirming or disconfirming patterns among students. Out-of-school experiences were the strongest determinant of student ability to engage in discourse that was compatible with experts. Students held incomplete understanding of pest-related benchmarks as indicated in their lack of ability to make connections between scientific, societal, and technological concepts. Informants lacked language to accurately articulate an understanding of the pest-related benchmarks. Most informants, especially urban, nongardening students lacked an understanding of pests and their control in the growth of plants for food. Core biological concepts, e. g. plant growth needs, may provide a structure for integrating agri-food system principles into the elementary school curriculum.

Published: September 2023

This research is motivated by the limited human resources and educational facilities in Kuta Inang Village compared to the community's need for Islamic education. The need for teachers or Quran teachers and educational facilities such as Taman Pendidikan Alquran is still very limited. The aim of this research is to make children accustomed to reciting the Quran, memorizing some short surahs, and daily prayers. In addition, it aims to provide religious lectures by STAI As-Sunnah KKL students to villagers as enlightenment and guidance to continue their enthusiasm for seeking knowledge of Islamic religion. The method applied in this research is Asset Based Community Development (ABCD) with 5 stages of asset reinventing through data collection (observation and FGD), designing types of activities, communicating the activities to potential beneficiaries, implementing the activities, and evaluating them. The results show that participants in the Quranic recitation quarantine have been able to memorize short surahs that they can read during prayer. In terms of performing ablution and prayer, the participants have also mastered the techniques. During the competition, they were very enthusiastic about participating in the activities. From these results, continuity of the activities is needed to address the challenges of limited Islamic teaching in Kuta Inang Village through a collaborative program between the village officials and campus/NGO partners.
Midline and Extended Dwell Catheters for IV Antibiotics
Authors: Hao Qiukui , Horton Jennifer
Published: September 2023

Midline catheters may be associated with longer uncomplicated indwelling time and a lower overall risk of catheter-related complications than extended dwell catheters.

The rates of catheter-related complications were low across different peripheral catheter types.

Midline catheters may have a lower proportion of catheter-related bloodstream infections, drug leakage from the exit site, and complete catheter occlusion, but a higher proportion of catheter-related thrombosis events compared with extended dwell catheters.

The findings were derived from 1 retrospective cohort study with imbalanced baseline characteristics of patients, and the limitations of the study may have favoured midline catheters; future studies are needed to confirm our findings.

We did not find any systematic reviews, health technology assessments, randomized controlled trials, or evidence-based guidelines that met our inclusion criteria.

Objetiva-se, portanto, apresentar a literatura como uma ferramenta de superação da crise, ao proporcionar um ensino mais reflexivo e menos automatizado do direito. Para tanto, procede-se à pesquisa bibliográfica sobre a história do curso de direito no Brasil, os fatores que culminaram na crise e o movimento "direito e literatura". Finalmente, serão analisados estudos que evidenciam o papel da literatura como agente de formação crítica e humanizada. Parte-se da hipótese de que a literatura pode contribuir para repensar o ensino jurídico, fornecendo uma abordagem mais humanizada e empática na formação do jurista, resultando em profissionais mais bem preparados para enfrentar as complexidades da atualidade, sendo, assim, fator de superação na crise do ensino jurídico. Isso porque a literatura possui imenso potencial humanizador e, ao expor o leitor a realidades diversas, instiga o pensamento crítico, fomentando a possibilidade de mudanças na realidade social brasileira. Acredita-se que a presente pesquisa possa trazer benefícios significativos para a formação dos juristas no Brasil, resultando em uma prática mais reflexiva, crítica e humanizada no campo do direito.
Methane retrievals from airborne HySpex observations in the shortwave infrared

Published: September 2023

Abstract. Monitoring anthropogenic emissions is a crucial aspect in understanding the methane budget. Moreover, a reduction of methane emissions could help to mitigate global warming on a short timescale. This study compares various retrieval schemes for estimating localized methane enhancements around ventilation shafts in the Upper Silesian Coal Basin in Poland using nadir observations in the shortwave infrared acquired from the airborne imaging spectrometer HySpex. Linear and nonlinear solvers are examined and compared, with special emphasis put on strategies that tackle degeneracies between the surface reflectivity and broad-band molecular absorption features – a challenge arising from the instrument's low spectral resolution. Results reveal that the generalized nonlinear least squares fit, employed within the Beer InfraRed Retrieval Algorithm (BIRRA), can measure enhanced methane levels with notable accuracy and precision. This is accomplished by allowing the scene's background covariance structure to account for surface reflectivity statistics. Linear estimators such as matched filter (MF) and singular value decomposition (SVD) are able to detect and, under favorable conditions, quantify enhanced levels of methane quickly. Using k-means clustering as a preprocessing step can further enhance the performance of the two linear solvers. The linearized BIRRA fit (LLS) underestimates methane but agrees on the enhancement pattern. The non-quantitative spectral signature detection (SSD) method does not require any forward modeling and can be useful in the detection of relevant scenes.
In conclusion, the BIRRA code, originally designed for the retrieval of atmospheric constituents from spaceborne high-resolution spectra, turned out to be applicable to hyperspectral airborne imaging data for the quantification of methane plumes from point-like sources. Moreover, it is able to outperform well-established linear schemes such as the MF or SVD at the expense of high(er) computing time.

Abstract. Cloud seeding experiments for modifying cloud and precipitation have been underway for nearly a century; yet practically all the attempts to link precipitation enhancement or suppression to the presence of seeding materials remained inclusive. In 2019, the Cloud-Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) implemented a novel method to detect seeded clouds during its operations in Solapur, India. In this experiment, residuals of cloud hydrometeors in seeded and non-seeded clouds were analyzed with an airborne mini-Aerosol Mass Spectrometer (mAMS). The mAMS instrument was utilized in conjunction with a counterflow virtual impactor (CVI) inlet, which had a cutoff diameter size of approximately 7 µm. Upon traversing the CVI inlet, the cloud droplets underwent a drying process, enabling the subsequent examination of cloud residuals through the mAMS instrument to identify potential seeding signatures. The Chlorine (Cl) associated with hygroscopic materials, i.e., Calcium Chloride (CaCl2) and potassium (K), which serve as the oxidizing agents in the flares, is found in relatively higher concentrations in the seeded clouds compared to the non-seeded clouds. After seeding, small-size cloud droplet concentrations increased in the convective and stratus clouds. In the convective clouds, flare particles propagated to higher cloud depths (≈ 2.25 km, vertical distance from cloud base) and modulate cloud microphysical properties to initiate warm rain. This new technique help to trace activated flare particles in seeded clouds and identify the post-seeding chain of cloud microphysical processes.
Parallel electric fields produced by ionospheric injection
Authors: Saka Osuke
Published: September 2023

Abstract. It is well known that there exists a thin layer in the lower boundary of the
ionosphere between altitudes of 80 and 140 km in which collisional ions
and collisionless electrons mix. Local breakdown of charge neutrality may be
initiated in this layer by electric fields from the magnetosphere as well as
by electric fields generated there by the local neutral winds. The breakdown
may be momentarily canceled by Pedersen currents, but complete neutralization is prevented because some ionospheric plasmas are released as
outflows by parallel electric fields. Those parallel electric fields are
produced by inherent plasma processes in the polar ionosphere and act as
auroral drivers. A new scenario creating parallel potential gradients is
proposed.
Rethinking the deployment of static chambers for CO2 flux measurement in dry desert soils
Authors: Bekin Nadav , Agam Nurit
Published: September 2023

Abstract. The mechanisms underlying the soil CO2 flux (Fs) in dry
desert soils are not fully understood. To better understand these processes,
we must accurately estimate these small fluxes. The most commonly used
method, static chambers, inherently alters the conditions that affect the
flux and may introduce errors of the same order of magnitude as the flux
itself. Regional and global assessments of annual soil respiration rates are
based on extrapolating point measurements conducted with flux chambers. Yet,
studies conducted in desert ecosystems rarely discuss potential errors
associated with using static chambers in dry and bare soils. We hypothesized
that a main source of error is the collar protrusion above the soil surface.
During the 2021 dry season, we deployed four automated chambers on collars
with different configurations in the Negev, Israel. Fs exhibited a
repetitive diel cycle of nocturnal uptake and daytime efflux. CO2 uptake
measured over the conventionally protruding collars was significantly lower
than over the collars flushed with the soil surface. Using thermal imaging,
we proved that the protruding collar walls distorted the ambient heating and
cooling regime of the topsoil layer, increasing the mean surface
temperatures. Higher soil temperatures during the night suppressed the flux
driving forces, i.e., soil–atmosphere CO2 and temperature gradients,
ultimately leading to an underestimation of up to 50 % of the actual Fs.
Accordingly, the total daily CO2 uptake by the soil in the conventionally
deployed collars was underestimated by 35 %. This suggests that desert
soils are a larger carbon sink than previously reported and that drylands,
which cover approximately 40 % of Earth's terrestrial surface, may play a
significant role in the global carbon balance.
Failure strength of glacier ice inferred from Greenland crevasses
Authors: Grinsted Aslak , Rathmann Nicholas Mossor , Mottram Ruth , Solgaard Anne Munck , Mathiesen Joachim , Hvidberg Christine Schøtt
Published: September 2023

Abstract. Ice fractures when subject to stress that exceeds the material failure strength. Previous studies have found that a von Mises failure criterion, which places a bound on the second invariant of the deviatoric stress tensor, is consistent with empirical data. Other studies have suggested that a scaling effect exists, such that larger sample specimens have a substantially lower failure strength, implying that estimating material strength from laboratory-scale experiments may be insufficient for glacier-scale modelling. In this paper, we analyze the stress conditions in crevasse onset regions to better understand the failure criterion and strength relevant for large-scale modelling. The local deviatoric stress is inferred using surface velocities and reanalysis temperatures, and crevasse onset regions are extracted from a remotely sensed crevasse density map. We project the stress state onto the failure plane spanned by Haigh–Westergaard coordinates, showing how failure depends on mode of stress. We find that existing crevasse data is consistent with a Schmidt–Ishlinsky failure criterion that places a bound on the absolute value of the maximal principal deviatoric stress, estimated to be (158 ± 44) kPa. Although the traditional von Mises failure criterion also provides an adequate fit to the data with a von Mises strength of (265 ± 73) kPa, it depends only on stress magnitude and is indifferent to the specific stress state, unlike Schmidt–Ishlinsky failure which has a larger shear failure strength compared to tensile strength. Implications for large-scale ice-flow and fracture modelling are discussed.
Non-mycorrhizal root-associated fungi increase soil C stocks and stability via diverse mechanisms
Authors: Stuart Emiko K. , Castañeda-Gómez Laura , Buss Wolfram , Powell Jeff R. , Carrillo Yolima
Published: September 2023

Abstract. While various root-associated fungi could facilitate soil carbon (C) storage and therefore aid climate change mitigation, so far research in this area has largely focused on mycorrhizal fungi, and potential impacts and mechanisms for other fungi are largely unknown. Here, we assessed the soil C storage potential of 12 root-associated, non-mycorrhizal fungal isolates (spanning nine genera and selected from a wide pool based on traits potentially linked to soil C accrual) and investigated fungal, plant and microbial mediators. We grew wheat plants inoculated with individual isolates in chambers allowing continuous 13C labelling. After harvest, we quantified C persistence, and pools of different origin (plant vs soil) and of different stability with long-term soil incubations and size/density fractionation. We assessed plant and microbial community responses, as well as fungal physiological and morphological traits in a parallel in vitro study. While inoculation with three of the 12 isolates resulted in significant total soil C increases, soil C stability improved under inoculation with most isolates – as a result of increases in resistant C pools and decreases in labile pools and respired C. Further, these increases in soil C stability were positively associated with various fungal traits and plant growth responses, including greater fungal hyphal density and plant biomass, indicating multiple direct and indirect mechanisms for fungal impacts on soil C storage. We found more evidence for metabolic inhibition of microbial decomposition than for physical limitation under the fungal treatments. Our study provides the first direct experimental evidence in plant-soil systems that inoculation with specific non-mycorrhizal fungal strains can improve soil C storage, primarily by stabilising existing C. By identifying specific fungi and traits that hold promise for enhancing soil C storage, our study highlights the potential of non-mycorrhizal fungi in C sequestration and the need to study the mechanisms underpinning it.
An optimisation method to improve modelling of wet deposition in atmospheric transport models: applied to FLEXPART v10.4
Authors: Van Leuven Stijn , De Meutter Pieter , Camps Johan , Termonia Piet , Delcloo Andy
Published: September 2023

Abstract. Wet deposition plays a crucial role in the removal of aerosols from the atmosphere. Yet, large uncertainties remain in its implementation in atmospheric transport models, specifically in the parameterisation schemes that are often used. Recently, a new wet deposition scheme was introduced in FLEXPART. The input parameters for its wet deposition scheme can be altered by the user and may be case-specific. In this paper, a new method is presented to optimise the wet scavenging rates in atmospheric transport models such as FLEXPART. The optimisation scheme is tested in a case study of aerosol-attached 137Cs following the Fukushima Daiichi nuclear power plant accident. From this, improved values for the wet scavenging input parameters in FLEXPART are suggested.
Evaluation of multi-season convection permitting atmosphere - mixed layer ocean simulations of the Maritime Continent

Published: September 2023

Abstract. A multi-season convection permitting regional climate simulation of the Maritime Continent using the Met Office Unified Model with 2.2-km grid spacing is presented and evaluated. The simulations pioneer the use of atmosphere-ocean coupling with the multi-column K profile parametrisation (KPP) mixed layer ocean model in atmospheric convection permitting climate simulations. Comparisons are made against a convection parametrised simulation in which it is nested, and which in turn derives boundary conditions from ERA5 reanalysis. This paper describes the configuration, performance of the mean state and variability of the two simulations compared against observational datasets. The models both have minor sea surface temperature (SST) and wet precipitation biases. The diurnal cycle, representation of equatorial waves and relationship between SST and precipitation are all improved in the convection permitting model compared to the convection parametrised model. The MJO is present in both models with a faster than observed propagation speed. However, it is unclear whether fidelity of the MJO simulation is inherent to the model or whether it predominantly arises from the forcing at the boundaries.
AutoATES v2.0: Automated avalanche terrain exposure scale mapping
Authors: Toft Håvard Boutera , Sykes John , Schauer Andrew , Hendrikx Jordy , Hetland Audun
Published: September 2023

Abstract. This paper documents substantial improvements to the original automated avalanche terrain exposure mapping (AutoATES v1.0) algorithm. The most significant drawbacks of AutoATES v1.0 have been addressed by including forest density data, improving the avalanche runout estimations in low-angle runout zones, accounting for overhead exposure and open-source software. The algorithm also supports the new ATES v2.0 terrain class ‘extreme’ terrain. We used two benchmark maps from Bow Summit and Connaught Creek to validate the improvements from AutoATES v1.0 to v2.0. For Bow Summit, the F1 score (a measure of how well the algorithm performs) improved from 64.01 % to 77.30 %. For Connaught Creek, the F1 score improved from 39.81 % to 71.38 %. The main challenge limiting large-scale mapping is the determination of optimal input parameters for different regions and climates. In areas where AutoATES v2.0 is applied, it can be a valuable tool for avalanche risk assessment and decision. Ultimately, our goal is for AutoATES v2.0 to enable efficient, large-scale, and potentially global ATES mapping in a standardized manner rather than based solely on expert judgement.
Monitoring main ocean currents of the IBI region
Authors: de Pascual-Collar Álvaro , Aznar Roland , Levier Bruno , Sotillo Marcos García
Published: September 2023

Abstract. The Iberia-Biscay-Ireland (IBI) region is located on the eastern margin of the North Atlantic. This geographical position results in a diverse array of currents, primarily including southward surface currents (associated to the North Atlantic subtropical gyre) and poleward slope currents at intermediate depths following the continental margins of Africa and Europa. Ocean currents have significant climatic, environmental, economic, and social implications, making them a crucial parameter whose variability needs to be monitored to anticipate diagnosis and support decision-making in the face of changing scenarios. The present study proposes a methodology that allows for systematic monitoring of ocean currents. This methodology is based on calculating volume transports within monitoring windows defined using: (i) present knowledge of the ocean and (ii) delineation of the water mass to be monitored based on its density range. The proposed indicator is computed using various sources of observational and modeling data, resulting in a multiproduct output. This approach provides not only an Ocean Monitoring Indicator (OMI) of transport anomalies but also an analysis of uncertainties. The calculation of this OMI on the currents in the IBI region shows that, despite the high uncertainties, the index is capable of detecting events of high/low transport intensity as well as significant transport trends superimposed on the interannual variability of some of the analyzed currents.
Basal Sliding and Hydrological Drainage at Baltoro Glacier

Published: September 2023

Abstract. Surface meltwater directly influences glacier velocity, as liquid water at the bed allows the glacier to slide. However, prolonged discharge of water at the bed increases the efficiency of the drainage system and decreases the amount of sliding. Due to the presence of an insulating debris mantle, debris-covered glaciers respond in a more complex way to changes in climate than those that are debris-free. The influence of higher temperatures on melt processes and, subsequently, supraglacial lake formation, and the triggers of basal sliding have not yet been sufficiently analyzed and understood. We present a spatio- temporal analysis of key glacier characteristics for the Baltoro Glacier in the Karakoram, from October 2016 to September 2022 based from Earth Observation data and climate parameters extracted from the High Asia Refined analysis (HAR) data set. For the glacier variables, we used surface velocity, supraglacial lake extent, snowmelt, and runoff derived from Earth Observation data. For climate variables, we focused on air temperature and precipitation. The relationship and dependency between the variables were examined with Pearson correlation and linear regression, respectively. Additionally, the temporal delay between snowmelt peak and glacier flow acceleration was determined. The surface velocity of the Baltoro Glacier was characterized by a spring speed-up, summer peak, and fall speed-up with the largest increase in spring of 1.0–1.7 m d-1 triggered by the onset or an increase of basal sliding. Snowmelt has the largest impact to the spring speed-up, summer velocity peak, and to the transition from inefficient to efficient drainage. The temporal delay between the initial peak of seasonal snowmelt and the first relative velocity maximum seems to decrease during the observation period. Drainage from supraglacial lakes contributed to the fall speed-up, which showed a lower magnitude by 0.1–0.2 m d-1 than the summer velocity peak. Wet snow covered up to 64 % (353 km2) of the complete Baltoro Glacier and reached up to to 4700 m a.s.l. during the first melt peak and up to 5600 m a.s.l. during summer. In comparison, the supraglacial lake area ranged between 3.6–5.9 km2. Most of the runoff can be attributed to snowmelt. However from mid-June onwards, the lakes play an increasing role, even though their contribution is estimated to be only about half of that of the snowmelt. The observed increase in summer temperatures influences the magnitude of snowmelt, as well as the formation of supraglacial lakes. This tendency is expected to intensify in the future.
Chrzest Polski

Źródła zanotowały ścisłą datę (rok) przyjęcia chrztu św. przez naszego pierwszego historycznego władcę — Mieszka I. Ponieważ nie mamy żadnego powodu powątpiewać w jej ścisłość, jubileusz obchodzony w roku 1966 był jest wynikiem nie konwencji, ale rzeczywiście jubileuszem tysiąclecia chrystianizacji naszego państwa. Był to moment niewątpliwie najważniejszy w naszych dziejach. Bez niego nie bylibyśmy tym, czym jesteśmy, gdyż nie przyjąwszy chrześcijaństwa nie zachowalibyśmy się jako osobny, żyjący i rozwijający się naród. Utraciwszy wcześniej czy później państwo, utracilibyśmy z pewnością indywidualność narodową. Przyjąwszy chrześcijaństwo od Kościoła rzymskiego staliśmy się częścią świata kultury łacińskiej. Autor w poniższym artykule poddał analizie dostępne źródła historyczne dotyczące tego ważnego wydarzenia w dziejach naszego narodu.

. The aim of the work is to identify the geological and geochemical features of the granitoids of the Akchatau massif. This article discusses the petrochemical data of the first and second phase introduction of the Akchatau massif, as well as the petrogenesis of rocks and the distribution conditions of tungsten and molybdenum. To diagnose the distribution of elements, the data were normalized by UCC. According to the results of the analysis, it was found that the chemical analysis of REE for granites is less than for leukogranites. It was also found that the REE distribution graph in the rocks of the Akchatau massif repeats the line of the upper crust.

The main goal of the research work described in the article is to determine the optimal operating mode of the future electric pulse silencer to solve the problem of efficient cleaning of exhaust gases of an internal combustion engine (ICE) by an electric pulse. According to the purpose of the study, a number of research methods are used in the article, in particular, the physical essence of the process of electropulse cleaning of exhaust gases of internal combustion engines of cars is described and an analysis of known patents in this direction is carried out, as well as experimental installations designed to determine the mode of neutralization of exhaust gases based on such parameters as voltage, duty cycle, distance between electrodes. The devices were made from various electrically conductive materials. Preliminary experiments on the units showed that under the action of an electric pulse, an increased oxygen content was observed in the exhaust gas, which gave rise to a hypothesis about the possibility of determining the optimal operating mode of an electric pulse silencer. In support of the hypothesis put forward, the task was to develop the design of an electric pulse silencer and a method for cleaning exhaust gases to optimize its operation. As a result of the implementation of the task, a patent was obtained for a utility model that characterizes the design of an electric pulse silencer and the method of gas cleaning by an electric pulse
