Координаталарды анықтаудың жерсеріктік технологияларын іске асыру жер қойнауын игеру кезінде геодезиялық негіз құру және кеніштерде маркшейдерлік-геодезиялық жұмыстарды жүргізу үшін жаңа мүмкіндіктер ашады. Осыған байланысты эллипсоидтың бетінде автоматтандырылған әдіспен алынған координаттарды қалыпты тік сызыққа бағытталған көлденең жергілікті проекцияға аударудың маңызы өте зор. Бұл тәсіл жер қойнауын игеру кезінде геодинамикалық полигон (ГДП) құруда, және де жобалық шешімдерді нақтылы жерге көшіруге мүмкіндік береді. Мақалада топоцентрлік координаттары бар жергілікті тегіс бетті қолданудан тұратын геодинамикалық полигонды қалыптастырудың өзекті ұстанымы ұсынылған. Сонымен қатар, геоцентрлік жүйеден топоцентрлік жүйеге координаталарды аударудың еспетеулері мен өлшеу нәтижелерін теңестірудің нақтылы мысалдары келтірілген
The introduction of satellite technologies for determining coordinates opens up new opportunities both for creating a geodetic basis for the development of the subsoil, and for the production of surveying and geodetic works at mines. In this regard, it seems very promising to transfer the coordinates obtained by an automated method on the surface of an ellipsoid to a horizontal local projection oriented normally to a vertical line. Such an approach to the creation of a geodynamic polygon (GDP) during the development of the subsoil will certainly make it possible to more accurately make design decisions in kind. The article proposes an up-to-date approach to the formation of a geodynamic polygon, which consists in the use of a local flat surface with topocentric coordinates. Calculations and concrete examples of the translation of coordinates from a geocentric system to a topocentric one are given, in which the measurement results are equalized
Внедрение в жизнь спутниковых технологий определения координат открывает новые возможности как для создания геодезической основы при освоении недр, так и производства маркшейдерско-геодезических работ на рудниках. В этой связи представляется весьма перспективным перевод координат, получаемых автоматизированным способом на поверхности эллипсоида, на горизонтальную локальную проекцию, ориентированную нормально отвесной линии.Такой подход к созданию геодинамического полигона (ГДП) при освоении недр безусловно позволит точнее выносить проектные решения в натуру. В статье предложен актуальный подход к формированию геодинамического полигона, заключающийся в применении локальной плоской поверхности с топоцентрическими координатами. Приводятся выкладки и конкретные примеры перевода координат из геоцентрической системы в топоцентрическую, в которой производится уравнивание результатов измерений

В данной статье рассмотрен способ крепления вентиляционного шурфа на месторождении Жаман-Айбат, Карагандинской области, т.к. в настоящее время стенки шурфа остаются незакрепленными. В условиях рудника Жомарт шурфы были пройдены задолго до возведения крепи, поэтому секционный способ крепления не может быть реализован для горных выработок. Исходя из зависимости параметров крепи основной части ствола, от действующих в массиве напряжений, выполняется оценка напряженно-деформированного состояния. Для данного рудника определена длина анкеров и расстояние между ними. Определена технология крепления бортов и устьев шурфов, расчитаны длина анкеров и толщина торкретбетона. Крепь шурфа должна состоять из двух частей: возле устья закреплена монолитной железобетонной крепью и основную часть ствола рекомендуется крепить комбинированной крепью
Бұл мақалада Қарағанды облысы, Жаманай-Айбат кен орнында желдеткіш шурфты бекіту әдісі қарастырылған, себебі қазіргі уақытта шурфтың қабырғалары бекітілмеген күйінде қалып отыр. Жомарт кенішінің жағдайында шурфтар бекіткіш тұрғызылғанға дейін ұзақ уақыт өткен, сондықтан секциялық бекіту әдісін тау-кен қазбалары үшін іске асыру мүмкін емес. Магистральдың негізгі бөлігін бекіту параметрлерінің массивтегі кернеулерге тәуелділігіне сүйене отырып, кернеулі деформацияланған күйді бағалау жүргізіледі. Бұл кеніш үшін якорьдің ұзындығы және олардың арасындағы қашықтық анықталады. Шурфтардың бүйірлері мен сағаларын бекіту технологиясы анықталды, якорьдің ұзындығы мен бетон торкретінің қалыңдығы есептелді. Шурфтың бекіткіші екі бөліктен тұруы керек: сағаның жанында монолитті темірбетон бекіткішпен бекітілген және магистральдың негізгі бөлігін біріктірілген бекіткішпен бекіту ұсынылады
This article discusses the method of fixing the ventilation pit at the Zhaman-Aybat deposit, Karaganda region, because at present the walls of the pit remain not fixed. In the conditions of the Zhomart mine, the pits were passed long before the construction of the support, so the sectional method of fastening cannot be implemented for mining. Based on the dependence of the parameters of the support of the main part of the trunk on the stresses acting in the array, the stress-strain state is evaluated. The length of the anchors and the distance between them are determined for this mine. The technology of fixing the sides and mouths of the pits is determined, the length of the anchors and the thickness of the shotcrete concrete are calculated. The pit support should consist of two parts: it is fixed near the mouth with a monolithic reinforced concrete support and it is recommended to attach the main part of the trunk with a combined support

Abstract. Chemical ionization mass spectrometry (CIMS) is widely used in atmospheric chemistry studies. However, due to the complex interactions between reagent ions and target compounds, chemical understanding remains limited and compound identification difficult. In this study, we apply machine learning to a reference dataset of pesticides in two standard solutions to build a model that can provide insights from CIMS analyses in atmospheric science. The CIMS measurements were performed with an orbitrap mass spectrometer coupled to a thermal desorption multi-scheme chemical ionization inlet unit (TD-MION-MS) with both negative and positive ionization modes utilizing Br-, O2-, H3O+ and (CH3)2COH+ (AceH+) as reagent ions. We then trained two machine learning methods on this data: 1) random forest (RF) for classifying if a pesticide can be detected with CIMS, and 2) kernel ridge regression (KRR) for predicting the expected CIMS signals. We compared their performance on five different representations of the molecular structure: the topological fingerprint (TopFP), the molecular access system keys (MACCS), a custom descriptor based on standard molecular properties (RDKitPROP), the Coulomb matrix (CM) and the many-body tensor representation (MBTR). The results indicate that MACCS outperforms the other descriptors. Our best classification model reaches a prediction accuracy of 0.85 ± 0.02 and a receiver operating characteristic curve area of 0.91 ± 0.01. Our best regression model reaches an accuracy of 0.44 ± 0.03 logarithmic units of the signal intensity. Subsequent feature importance analysis of the classifiers reveals that the most important structural fragments are NH and OH for the negative ionization schemes and nitrogen-containing groups for the positive ionization schemes.
Precipitation extremes in Ukraine from 1979 to 2019: climatology, large-scale flow conditions, and moisture sources

Abstract. Understanding extreme precipitation events (EPEs) and their underlying dynamical processes and moisture transport patterns is essential to mitigating EPE-related risks. In this study, we investigate the dynamics of 82 EPEs (≥100 mm d−1) over the territory of Ukraine in the recent decades (1979–2019), of which the majority occurred in summer. The EPEs are identified based on precipitation observations from 215 meteorological stations and posts in Ukraine. The atmospheric variables for the case study analysis of selected EPEs and for climatological composites and trajectory calculations were taken from ERA5 reanalyses. Moisture sources contributing to the EPEs in Ukraine are identified with kinematic backward trajectories and the subsequent application of a moisture source identification scheme based on the humidity mass budget along these trajectories. The large-scale atmospheric circulation associated with EPEs was studied for a selection of representative EPEs in all seasons and with the aid of composites of all events per season. Results show that EPEs in summer occur all across Ukraine, but in other seasons EPE hotspots are mainly in the Carpathians and along the Black Sea and Sea of Azov. All EPEs were associated with a surface cyclone, with most having an upper-level trough, except for the winter events that occurred in situations with very strong westerly jets. Isentropic potential vorticity anomalies associated with EPEs in Ukraine show clear dipole structures in all seasons, however, interestingly with a different orientation of these anomaly dipoles between seasons. The analysis of moisture sources revealed a very strong case-to-case variability and often a combination of local and remote sources. Oceanic sources dominate in winter, but land evapotranspiration accounts for 60 %–80 % of the moisture that rains out in EPEs in the other seasons. Taken together, these findings provide a novel insight into large-scale characteristics of EPEs in Ukraine, a region with a unique geographical setting and with moisture sources as diverse as Newfoundland, the Azores, the Caspian Sea, and the Arctic Ocean.

ABSTRACT
Currently, the tire industry is exploring eco-friendly tires with improved rolling resistance, traction, abrasion resistance, and fatigue properties. The present study investigates the potentiality of the hydrogenated styrene butadiene rubber (HSBR), a special and modified grade of styrene butadiene rubber (SBR) as a tyre tread material. The rheological, mechanical, dynamic mechanical, abrasion resistance, fatigue resistance, aging resistance and ozone resistance properties of the developed HSBR-based composites were critically evaluated and compared with those of conventional rubbers such as natural rubber (NR), emulsion styrene butadiene rubber (ESBR) and solution styrene butadiene rubber (SSBR) based composites. Interestingly, the HSBR-based vulcanizates exhibited superior modulus, tensile strength, abrasion resistance, fatigue crack growth resistance, resistance to thermo-oxidative aging, and ozone resistance as compared to the conventional SBR–based vulcanizates. The modulus at 300% elongation of the HSBR-based vulcanizate was approximately 74% and 11% higher than that of the ESBR- and SSBR-based composites, respectively, whereas the improvements in tensile strength were approximately 88% and 64% and the improvements in abrasion resistance were approximately 250% and 200% than that of the ESBR and SSBR vulcanizates, respectively. The tensile strength and fatigue resistance characteristics of the HSBR vulcanizate were also nearly similar to those of the NR vulcanizate. The findings demonstrate that HSBR can be a potential tire tread material with robust physico-mechanical properties and durability.
Commercialization: A hatch in the sociological diagnosis of our time
Authors: Genov Nikolai 
Published: July 2024

<p> Max Weber feared a social future dominated by rational specialists “without spirit”. He considered this development a possible outcome of the interplay between all-embracing commercialization (marketization, monetization) with the rationalization (bureaucratization) of structures and processes in industrialized societies. Another observation of Weber concerned the ongoing replacement of medieval religious values with secularized-rationalist and profit-oriented ones. The predominance of such values usually fosters work productivity but also raises profound questions about the changing specifics of money. They have become central to the value systems at local, regional, and global levels. Weber was pessimistic concerning the fate of commercialization. Edward A. Ross substantially contributed to the study of commercialization as part and parcel of his efforts to put a sociological diagnosis on American society after WWI. He selected and analysed a dozen constructive and destructive cases of commercialization. Talcott Parsons studied the phenomenon in detail and called it “instrumental activism”. George Ritzer’s study on McDonaldization as a rationalization process is an effort to put a sociological diagnosis on global society. There are open questions concerning the capacity of contemporary societies and individuals to manage innovations for coping with commercialization. The empirical reference for the discussion is SpaceX, led by Elon Musk.</p>

O objetivo desse trabalho foi avaliar o desempenho agronômico de variedades comerciais de soja lançadas para a safra 2022/2023, no município de Palmeiras de Goiás, Goiás. O ensaio experimental foi realizado em campo, conduzido em delineamento em blocos casualizados, com sete cultivares (B43, DM 69IX6912X, Olimpo, TMG 2279, FT 3165, STINE 77EA40 e M7601) e quatro repetições. Cada parcela experimental foi constituída por cinco fileiras de 4 m e com espaçamento entre linhas de 0,5 m. A área do ensaio experimental foi de 16 x 38 m, totalizando 608 m². Para a avaliação do desempenho agronômico foram avaliados os seguintes caracteres: porcentagem de emergência (PE), produtividade de grãos (PROD), número de vagens por planta (NVP), número de grãos por planta (NGP), peso de 100 grãos (P100), altura de plantas (ALT), área foliar (AF), concentrações foliares de clorofilas (Cl a+b) e carotenoides totais (CARAT). Os dados foram submetidos a análise de variância e a comparação das médias pelo teste de Tukey, a 5% de probabilidade, utilizando o software R. Os resultados da ANOVA apresentaram diferenças significativas (P < 0,05) entre as cultivares para as variáveis: PE, CLA, CLT, PROD, P100, NGP, ALT e AF. No entanto, não foram encontradas diferenças significativas para a variável teor de clorofila B (CLB), CARAT e AF. As cultivares avaliadas possuíam descrições técnicas similares quanto à resistência e produtividade, entretanto, na safra 2022/2023, na cidade de Palmeiras de Goiás a cultivar FT 3165 apresentou uma maior produtividade, quando comparada as demais, demonstrando-se ser a mais adaptada nessa região. Embora, todas as cultivares avaliadas tenham apresentado uma produtividade abaixo da média nacional obtida para a safra 2022/2023, o que provavelmente está relacionado às condições climáticas, como o veranico ocorrido logo após o plantio.
