Тау-кен металлургия кешенінің кәсіпорындарында ауыр роторлы жабдықты іске қосу мәселесі түінді болып табылады. Үлкен инерциялық массасы бар жабдықты пайдалану кезінде іске қосу режимдері ең қолайсыз режимдер болып табылады. Жабдықтың бұл түрін іске қосу кезінде іске қосу құрылғыларына жүктемелердің бірнеше есе артуы байқалады, бұл олардың ресурсының төмендеуіне, электр қозғалтқышының істен шығуына, электр энергиясының пайдалану шығындарының жоғарылауына және т.б. алып келеді. Бұл мақалада ауыр роторлы машиналардың іске қосу тогының мөлшеріне соңғы ажыратқышты орналастыру нүктесінің және жүйедегі қысымның әсерін зерттеу мақсатында тіреуішті іске қосу құрылғысының стендтік сынақтарының нәтижелері келтірілген. Іске қосу тогының сильфон цилиндрінің қуысындағы әртүрлі қысымдардағы жылжымалы траекториядағы соңғы қосқышты орнату нүктесіне тәуелділігінің графиктері алынды
At the enterprises of the mining and metallurgical complex, there is a problem of starting equipment with a heavy rotor. When operating equipment with a large inertial mass, the most unfavorable modes are the starting modes. During the start-up of this type of equipment, there is a multiple excess of loads on the starting devices, which leads to a failure of the electric motor, increased operating costs for electricity, etc. This article presents the results of bench tests of a rack-and-pinion starting device, in order to study the influence of the location point of the limit switch and the pressure in the system on the value of the starting current of machines with a heavy rotor. Graphs of the dependence of the inrush current on the installation point of the limit switch on the sliding trajectory at different pressures in the cavity of the bellows cylinder are obtained

В статье приведены результаты исследований по изучению эффективности применения контурного взрывания в породах с повышенной трещиноватостью при проходке подземных горных выработок на примере месторождения Западный Каражал. Обоснование эффективности применения контурного взрывания производилось на основе численного анализа путем определения зон возможных обрушений законтурного массива после техногенного воздействия. Численное моделирование методом конечных элементов выполнялось в условиях применения обычного способа взрывания и контурного взрывания. На основе результатов численного анализа установлено, что с применением контурного взрывания наблюдается увеличение запаса прочности приконтурной части массива и уменьшение зоны возможного обрушения вокруг горной выработки, а также на порядок уменьшается влияние силы взрыва на законтурный массив по сравнению с обычным способом взрывания

The article presents the results of research on the effectiveness of the use of contour blasting in rocks with increased fracturing during the sinking of underground mine excavations using the example of the Zapadny Karazhal deposit. The justification of the effectiveness of the use of contour blasting was carried out on the basis of numerical analysis by determining the zones of possible collapses of the contour array after man-made impact. Numerical modeling by the finite element method was performed under the conditions of using the conventional method of blasting and contour blasting. Based on the results of numerical analysis, it was found that with the use of contour blasting, there is an increase in the margin of safety of the contour part of the array and a decrease in the zone of possible collapse around the mine, as well as an order of magnitude decrease in the effect of the explosion force on the contour array compared to the conventional method of blasting
Socialisation citoyenne et représentations de l’altérité : apprendre à re-connaitre les points de vue des élèves avant d’ « éduquer à… »

Dans cet article, nous avons formulé quelques réflexions à l’égard des manières d’éduquer les plus jeunes à un sentiment du « Nous » basé sur l’idée de diversité. Les approches pédagogiques descendantes sont questionnées en parallèle des approches plus horizontales et participatives. Le projet ANR Affirmatif nous a permis de mener une enquête quantitative sur les manières dont des élèves de lycée réagissent face aux enjeux posés par la migration humaine internationale, ainsi que les attentes qu’elles/ils nourrissent envers l’école en matière de socialisation citoyenne. Nous avons interrogé 1 300 jeunes fréquentant des lycées en Région PACA (M âge 16.7). Le cadre qui ressort est multidimensionnel : a) l’école ne semble pas vraiment un contexte de socialisation politique alors que les attentes des élèves en matière d’éducation à la diversité sont importantes, b) les questions posées par l’immigration internationale sont une donnée qui est bien inscrite dans leurs représentations de la société, malgré certains enjeux qu’elle suscite soient appréhendées par un œil craintif, c) l’adhésion aux valeurs républicaines génère des effets inattendus sur les préjugés et les représentations de la diversité. Dans la discussion, nous mettons en exergue l’importance de mener des actions d’éducation à la citoyenneté participatives et horizontales qui se fondent dans la reconnaissance sans préjugements des opinions et des représentations des élèves.
Hors du social, de la culture et du monde, mais pas hors de soi ni de l’entre-soi : comment une relation pédagogique peut ne pas être citoyenne ?

Comment former interculturellement à la citoyenneté ? La convergence internationale dans le domaine de la formation en faveur de l’interculturel, des questions vives (Legardez & Simmonneaux, 2011), des compétences, de la réflexivité (Joly, 2022 ; Lucy, 2023), s’inscrit dans le double panorama, plus large, plus ancien et plus universel, de l’articulation entre citoyenneté (Schnapper, 2000) et inégalités sociales (Bourdieu & Passeron, 1964, 1970 ; Lahire, et al., 2019). Partout, la citoyenneté devient alors perçue d’abord sous l’angle du risque systémique d’ethnocentrisme, moteur des inégalités en éducation, à neutraliser pour que puissent se développer de réelles compétences réflexives universelles à l’interculturel et, plus largement, à l’ensemble des questions vives à travers le monde. Notre exemple empirique est idéal-typique de la posture en développement des futur-es enseignant-es comme intellectuel-les professionnel-les. Leur ethnocentrisme réel ou potentiel de facto reste selon nous le principal obstacle à tout interculturalisme. La solution réside dans le modèle universel du rapport distancié à ce soi (Schön, 1994), contre un entre-soi empêchant toute sortie de soi synonyme de réflexivité, principal obstacle à une réelle formation, dont l’origine se trouve dans leur rapport à l’institution scolaire, qui favorise une citoyenneté d’entre soi coupée du social, de la culture et du monde.

Abstract. Deep convection initiated under different large-scale environmental conditions exhibits different precipitation features and interacts with local meteorology and surface properties in distinct ways. Here, we analyze the characteristics and spatiotemporal patterns of different types of convective systems over southeastern Texas using 13 years of high-resolution observations and reanalysis data. We find that mesoscale convective systems (MCSs) contribute significantly to both mean and extreme precipitation in all seasons, while isolated deep convection (IDC) plays a role in intense precipitation during summer and fall. Using self-organizing maps (SOMs), we found that convection can occur under unfavorable conditions without large-scale lifting or moisture convergence. In spring, fall, and winter, front-related large-scale meteorological patterns (LSMPs) characterized by low-level moisture convergence act as primary triggers for convection, while the remaining storms are associated with an anticyclonic pattern and orographic lifting. In summer, IDC events are mainly associated with front-related and anticyclonic LSMPs, while MCSs occur more in front-related LSMPs. We further tracked the life cycle of MCS and IDC events using the Flexible Object Tracker algorithm over southeastern Texas. MCSs frequently initiate west of Houston, traveling eastward for around 8 h to southeastern Texas, while IDC events initiate locally. The average duration of MCSs in southeastern Texas is 6.1 h, approximately 4.1 times the duration of IDC events. Diurnally, the initiation of convection associated with favorable LSMPs peaks at 11:00 UTC, 3 h earlier than that associated with anticyclones.
Potential of 14C-based vs. ΔCO-based ΔffCO2 observations to estimate urban fossil fuel CO2 (ffCO2) emissions

Abstract. Atmospheric transport inversions are a powerful tool for independently estimating surface CO2 fluxes from atmospheric CO2 concentration measurements. However, additional tracers are needed to separate the fossil fuel CO2 (ffCO2) emissions from non-fossil CO2 fluxes. In this study, we focus on radiocarbon (14C), the most direct tracer of ffCO2, and the continuously measured surrogate tracer carbon monoxide (CO), which is co-emitted with ffCO2 during incomplete combustion. In the companion paper by Maier et al. (2024), we determined discrete 14C-based and continuous ΔCO-based estimates of the ffCO2 excess concentration (ΔffCO2) compared with a clean-air reference for the urban Heidelberg observation site in southwestern Germany. The ΔCO-based ΔffCO2 concentration was calculated by dividing the continuously measured ΔCO excess concentration by an average 14C-basedΔCO/ΔffCO2 ratio. Here, we use the CarboScope inversion framework adapted for the urban domain around Heidelberg to assess the potential of both types of ΔffCO2 observations to investigate ffCO2 emissions and their seasonal cycle. We find that, although they are more precise, 14C-based ΔffCO2 observations from almost 100 afternoon flask samples collected in the 2 years of 2019 and 2020 are not well suited for estimating robust ffCO2 emissions in the main footprint of this urban area, which has a very heterogeneous distribution of sources including several point sources. The benefit of the continuous ΔCO-based ΔffCO2 estimates is that they can be averaged to reduce the impact of individual hours with an inadequate model performance. We show that the weekly averaged ΔCO-based ΔffCO2 observations allow for a robust reconstruction of the seasonal cycle of the area source ffCO2 emissions from temporally flat a priori emissions. In particular, the distinct COVID-19 signal – with a steep drop in emissions in spring 2020 – is clearly present in these data-driven a posteriori results. Moreover, our top-down results show a shift in the seasonality of the area source ffCO2 emissions around Heidelberg in 2019 compared with the bottom-up estimates from the Netherlands Organization for Applied Scientific Research (TNO). This highlights the huge potential of ΔCO-based ΔffCO2 to validate bottom-up ffCO2 emissions at urban stations if the ΔCO/ΔffCO2 ratios can be determined without biases.

Abstract. The Tibetan Plateau (TP) hosts a variety of vegetation types, ranging from broadleaved and needle-leaved forests at the lower altitudes and in mesic areas to alpine grassland at the higher altitudes and in xeric areas. Accurate and detailed mapping of the vegetation distribution on the TP is essential for an improved understanding of climate change effects on terrestrial ecosystems. Yet, existing land cover datasets for the TP are either provided at a low spatial resolution or have insufficient vegetation types to characterize certain unique TP ecosystems, such as the alpine scree. Here, we produced a 10 m resolution TP land cover map with 12 vegetation classes and 3 non-vegetation classes for the year 2022 (referred to as TP_LC10-2022) by leveraging state-of-the-art remote-sensing approaches including Sentinel-1 and Sentinel-2 imagery, environmental and topographic datasets, and four machine learning models using the Google Earth Engine platform. Our TP_LC10-2022 dataset achieved an overall classification accuracy of 86.5 % with a kappa coefficient of 0.854. Upon comparing it with four existing global land cover products, TP_LC10-2022 showed significant improvements in terms of reflecting local-scale vertical variations in the southeast TP region. Moreover, we found that alpine scree, which is ignored in existing land cover datasets, occupied 13.99 % of the TP region, and shrublands, which are characterized by distinct forms (deciduous shrublands and evergreen shrublands) that are largely determined by the topography and are missed in existing land cover datasets, occupied 4.63 % of the TP region. Our dataset provides a solid foundation for further analyses which need accurate delineation of these unique vegetation types in the TP. TP_LC10-2022 and the sample dataset are freely available at https://doi.org/10.5281/zenodo.8214981 (Huang et al., 2023a) and https://doi.org/10.5281/zenodo.8227942 (Huang et al., 2023b), respectively.

Published: July 2024

This work aims to present the generalized Cayley graph and identify its structure in a few specific scenarios. Assume that Ψ is a finite-group and that S is a non-empty subset of Ψ.e ∉ S and S^-1<=S. As a result, the vertices of the Cayley graph Cay (Ψ,S) are all members of Ψ, and two nearby vertices, x and y, are only adjacent if xy^−1 ∈S. The given generalized Cayley graph is defined as \(Cay_m(G,S)\) This is a graph whose vertex set is made up of every column matrix \(X_m\) It has two vertices and all of its components in Ψ. \(X_m\) and \(Y_m\) are adjacent ↔ \(X_m[(Y_m)^-1]^t ∈\) M(S), where \(Y_m^-1\) is a column matrix in which ∀ entry correlates to an associated element's inverse. Y-m and M(S) is a m×m matrix where every entry is in S ,[y^-1]^i is the opposite of y^-1 andM>=1 . In this study, we assign the structure of the new graph and highlight some of its fundamental aspects \(Cay_m(G,S)\) when \(Cay(G,S)\) is the \(P_2\) X \(P_2\) and \(P_2\) X \(C_2\).
Priority of Low-Income Consumer Behaviour in Visiting Market Places
Authors: K. Abraham  
Published: July 2024

Need of the study: The competition among the marketers is at cutthroat type so, the marketers have to search for new avenues or the new segments for selling their goods and services. The present study will pave the way to the marketers and producers to reach the markets where the low-income consumers are available to purchase the goods and services at their potentiality.
Objectives:

To find the market places being visited by the low-income consumers.
To know the level of consumption expenditure of low-income consumer in a particular market place.
To find the market place where the low-income consumer is spending much.

Irrespective of their income level, most of the respondents from low-income consumers preferred ‘public distribution shops’ for food provisions whatever was available there. Secondly, they preferred to visit ‘retail shops’, ‘towns’, and ‘district head quarters’ were cited as the third’, ‘vendors’ as the fourth, and lastly ‘other sources’ as their preferred market places, from where they buy their products and services. (Table no: 3). There is relation between literacy level and visiting market place for purchasing goods and services. To say clearly based on their literacy level the low-income consumers market place priority is changing. Based on post hoc test it is found that there exists some similarity in the consumption expenditure of retail shops and district headquarters. But not in the case of public distribution shops. (Table no: 9). Under the keen competition it is suggested to the marketers to provide the necessary goods at Public Distribution Shops to reach the market which they have never met so far.
