DENSITY INHOMOGENEITIES AT THE BASE OF THE EARTH’S CRUST AND DETERMINATION OF ITS LOWER BOUNDARY
Authors: Кушнир Д.Г.
Published: August 2024

В последние годы благодаря развитию техники и технологии геофизических исследований глобальные геофизические обобщения глубинного геологического строения сочетаются с получением сверхдетальной информации по геотектонике и геодинамике. В основании новейших континентальных впадин по материалам глубинных сейсмических зондирований повсеместно фиксируется подъем характерных для мантии значений плотности и скорости распространения упругих колебаний. Согласно высокоплотным данным сейсморазведки на отраженных волнах, эти аномалии скорости и плотности соотносятся с развитием вещества коры, составляя с ней единый геодинамический механизм, обуславливающий прогибание. Широкое распространение коровых слоев, сопоставимых по своим свойствам с мантией, позволяет пересмотреть процессы образования континентов и открывает новые возможности для регионального прогноза минерагении.

In recent years, thanks to the development of technology and technology of geophysical research, global geophysical generalizations of the deep geological structure are combined with obtaining super-detailed information on geotectonics and geodynamics. At the base of the newest continental depressions, based on the materials of deep seismic sounding, anomalously high densities and propagation velocities of elastic vibrations characteristic of the mantle are recorded everywhere. According to high-density seismic data on reflected waves, these velocity and density anomalies correlate with the development of the crust substance, forming a single geodynamic mechanism with it, causing deflection. The wide distribution of crustal layers, comparable in their properties to the mantle, allows us to revise the processes of formation of continents and opens up new opportunities for the regional forecast of minerageny.

ULTRACONSOLIDATED SUPERCONTINENTAL EARTH CRUST ACCORDING TO THE TAIMYR GEOPHYSICAL POLYGON
Authors: Кушнир Д.Г.
Published: August 2024

Данные Таймырского геофизического полигона продемонстрировали, что крупнейшие прогибы маркируют концентрацию корового вещества, которая происходит за счет насыщения его мантийными флюидами и уплотнения, вплоть до полного превращения в эклогиты под наиболее выраженными депрессиями. Эта концентрация является предельно возможной, поскольку в основании прогибов кора состоит практически только из двух слоев - в разной степени дислоцированного осадочного чехла и эклогитизированной коромантийной смеси, то есть сосредоточение наиболее значимых масс на уровне раздела Мохоровичича в относительно тонком слое, обеспечивающем изостатическое прогибание, свидетельствует о ее сверхконсолидации. В то же время наибольшая плотность в сочетании с повышенной пластичностью обуславливает неустойчивость и разрушение консолидированного слоя интрузиями перидотитов верхней мантии, что неизбежно приводит впоследствии к изостатическому воздыманию и орогенезу депрессионного блока, лишенного массивного основания и обладающего существенным дефицитом плотности. Учитывая масштабы разуплотнения, связанного с максимально возможными мощностями осадков (до 30 км и более), орогенез, по-видимому, будет сопровождаться утолщением коры вплоть до экстремальных значений, и, следовательно, принимая во внимание предельную концентрацию корового вещества сегодня и неизбежное предельное утолщение в будущем, данный тип коры можно считать суперконтинентальным.

Data from the Taimyr geophysical polygon have demonstrated that the largest deflections mark the concentration of crustal matter, which occurs due to its saturation with mantle fluids and compaction, up to complete transformation into eclogites under the most pronounced depressions. This concentration is extremely possible, since at the base of the deflections the crust consists of practically only two layers - a dislocated sedimentary cover and an eclogitized coromantium mixture to varying degrees, that is, the concentration of the most significant masses at the level of the Mohorovichich section in a relatively thin layer providing isostatic deflection indicates its superconsolidation. At the same time, the highest density combined with increased plasticity causes instability and destruction of the consolidated layer by intrusions of upper mantle peridotites, which inevitably leads subsequently to isostatic uplift and orogeny of the depression block, devoid of a massive base and having a significant density deficit. Considering the scale of decompression associated with the maximum possible precipitation capacities (up to 30 km or more), orogeny is likely to be accompanied by a thickening of the crust up to extreme values, and, therefore, taking into account the maximum concentration of crustal matter today and the inevitable maximum thickening in the future, this type of crust can be considered supercontinental.

Среднеюрские отложения в пределах Среднекаспийского НГБ являются перспективным объектом для поиска залежей углеводородов и при этом слабоизученными: к настоящему моменту полный разрез среднеюрских образований на площади исследования вскрывает не более 10 скважин. По результатам предыдущих исследований в изучаемом разрезе было установлено наличие зоны аномально высокого порового давления (АВПД), приуроченной к терригенным преимущественно глинистым отложениям среднеюрского сиквенса 2-го порядка. В настоящей статье рассмотрено влияние АВПД на элементы среднеюрской углеводородной системы – коллектор, покрышку, нефтегазоматеринскую толщу, ловушку и взаимосвязь АВПД с протеканием процессов генерации, миграции и аккумуляции УВ. Для анализа и оценки вероятности наличия залежей в раз- резе была выполнена привязка элементов углеводородной системы с позиции сиквенсстратиграфии. Проведенный комплексный анализ позволил разделить территорию исследования на три зоны: непосредственно зону АВПД, зону разгрузки давления и зону гидростатического давления, оценить вероятность наличия элементов углеводородной системы и обозначить перспективы поиска залежей углеводородов (УВ) в каждой выделенной зоне. Результаты проведенного анализа могут выступать в качестве дополнительного материала для оценки перспектив нефтегазоносности слабоизученных среднеюрских отложений и планирования дальнейших геолого-разведочных работ в регионе.

Middle Jurassic formation of the Middle Caspian Basin is prospective target for oil and gas exploration, but is still understudied: only 10 wells have reached deep Middle Jurassic interval within the regional area of study. According to the previous studies the regional overpressure zone was identified in the terrigenous Middle Jurassic deposits of the 2nd order cycle sequence. The paper describes how overpressure affects the petroleum system elements, such as reservoir, seal, source rock, trap and petroleum fields processes, including generation, migration and accumulation. The play analysis for all petroleum system elements was based on sequence-stratigraphy model. The multidisciplinary study made it possible to divide the Middle Caspian basin area in three zones: overpressure zone, zone of pressure unloading and hydrostatic pressure zone and to estimate the probability of success for critical play elements and hydrocarbon potential for each zone. Obtained results provided additional data for oil-and-gas prospective estimation and planning of geological exploration directions in the Middle Caspian Basin.

Published: August 2024

Данное исследование посвящено построению и анализу синтетических AVO-сейсмограмм с использованием результатов петроупругого моделирования пород доманиковой формации, содержащих кероген. Исследование состоит из нескольких этапов. На первом этапе работы с помощью методов теории эффективных сред проведено теоретическое моделирование эффективных упругих свойств образцов пород доманиковых отложений. Далее были построены различные сейсмогеологические модели, в которых варьировалось содержание твердого органического вещества (керогена) в пласте и его пористость, ассоциированная с преобразованием керогена в нефть. На основе этих моделей были рассчитаны коэффициенты отражения от кровли и подошвы слоя, содержащего кероген. Для лучшей визуализации и анализа результатов построены синтетические AVO-сейсмограммы и проведен их анализ с учетом разного уровня зашумленности сейсмограмм.

This research is devoted to the theoretical modeling of synthetic AVO-seismograms using the results of petroelastic modeling of domanic formation rocks. The research consists of several stages: the first stage of the work consisted in the theoretical modeling of the effective elastic properties of rock samples of domanic deposits using the methods of the theory of effective media. Then various seismogeological models were constructed, where the content of solid organic matter (kerogen) in the formation and its porosity varied. Reflection coefficients were calculated based on these models. For better visualization and analysis, synthetic AVO-seismograms were constructed and analyzed.

В работе показаны результаты спектрально-временного анализа 3D сейсмоакустических данных МОГТ (метода отраженных волн в модификации общей глубинной точки) стандартного (СР) (частотный диапазон – 5–120 Гц), высокого (СВР) (90–500 Гц) и сверхвысокого (ССВР) (150–750 Гц) разрешения. Спектрально-временной анализ включал разложение сейсмических трасс на спектрограммы с использованием спектрально-временного преобразования Стоквелла. По полученным спектрограммам выявлены области интерференции, которые были учтены при выборе интервалов разреза для количественной оценки затухания. Анализ частотно-зависимого затухания сейсмических сигналов был основан на использовании метода сдвига центральной частоты.

The results of time-frequency analysis of 3D seismic reflection data surveys of standard (SR, 5–120 Hz), high (HR, 90–500 Hz) and very high (VH, 150–750 Hz) resolutions are presented. Time-frequency analysis included decomposition of seismic traces into spectrograms with the use of Stockwell Transform. According to the obtained spectrograms, interference areas were identified and taken into account when choosing the seismic section intervals for quantitative attenuation estimation. The analysis of the seismic impulse frequency-dependent attenuation is based on frequency shift method.

Стадийность геолого-поисковых работ заключается в переходе от общих поисков и, в случае положительных перспектив, к крупномасштабным работам, и заверочному бурению. Подчеркивается, что благодаря стадийности поиска удалось избежать дополнительных издержек. Весь комплекс работ, от аэрогеофизики до получения заключения о запасах и постановке на баланс, занял около 5 лет. Работы завершились открытием очень крупного золотого месторождения Роман и выделением ряда перспективных участков для последующих наземных заверочных работ специалистами компании Nordgold. Подтвержденные запасы золота составляют не менее 143 тонн.

here are several stages of geological survey: general survey, in the case of positive prospects, large-scale survey and well-drilling. We can avoid additional costs just using these stages consistently. The whole range of works, from airborne geophysics to receiving conclusions on reserves and putting on balance, took about 5 years. The whole work ended with the discovery of a very large gold deposit named Roman and the identification of a number of targets for ground survey by Nordgold specialists. Confirmed gold reserves are at least 5 Moz.

Published: August 2024

Рассмотрены структурно-геологические и термические условия образования и размещения антраксолитов – твердых битумов на территориях Пай-Хоя, о-ва Вайгач и архипелага Новая Земля. Обсуждается природа их появления в связи с геотермическим режимом недр. На основе численного моделирования рассчитаны температуры и плотность теплового потока в геометрии 2D вдоль сейсмогеологических профилей. Сделан вывод, что современная геотермическая обстановка в Пайхойско-Новоземельском поясе не способствует формированию антраксолитов, так как характеризуется относительно низкими температурами и тепловым потоком в земной коре. Локальное повышение температур можно ожидать только в разломных проницаемых зонах, где гидротермальная разгрузка может способствовать выведению антраксолитов с глубины.

The structural, geological and thermal conditions for the formation and placement of anthraxolites - solid bitumen in Pai-Khoi, Vaygach Island and the New Land territories are considered. Their appearance nature is discussed in connection with the geothermal regime of the subsoil. Based on numerical modeling, temperatures and heat flow were calculated in 2D geometry along seismic geological profiles. It is concluded that the current geothermal conditions in the Paikhoi-New Land belt are not promote to the anthraxolites formation, because characterized by relatively low temperatures and heat flow in the earth’s crust. Local increases in temperatures can be only expected in fault permeable zones, where hydrothermal discharge can facilitate the removal of anthraxolites from the depths.
Everyday practices of urban dwellers in the condi-tions of the COVID-19 pandemic: Russian and foreign experience
Authors: Ядова М. А.
Published: August 2024

Based on the results of Russian and foreign sociological research, the article analyses the changes that occurred in the everyday practices of city residents during the COVID-19 pandemic. The data of individual interviews conducted by the author with representatives of post-Soviet youth about their everyday practices and adaptation strategies in the conditions of lockdowns are presented. It is shown that for many ur-ban dwellers in Russia and abroad the stay in the regime of self-isolation became a time of not only limitations, but also new opportunities. For some people it became a time of mastering useful everyday online practices (creative, educational, leisure, labor, communicative, etc.), which they would like to keep in their lives even after the pan-demic. Some urban dwellers (especially young people) were involved in various forms of social activism and volunteering. It is noted that the COVID-19 pandemic, despite its many negative consequences, had an unusual positive emergent effect — in general, it contributed to the revitalization of some aspects of social life and gave impetus to the development of everyday social practices; this effect was especially noticeable in large cities where quarantine regimes were the most stringent. The author believes that the effective experience of young people adapting to the new coronavirus everyday life and similar unexpected crisis phenomena may be useful for the representatives of older generations
Scientific and methodological rationale for the development of a system of criteria for assessing the environmental safety of the urban environment
Authors: Цховребов Э. С.
Published: August 2024

The scientific and methodological substantiation of the system of criteria for assessing a safe urban environment was carried out in the study. The relevance of the study is due to the need to increase the level of validity and reliability of criteria for classifying events as an emergency situation (emergency), bearing environmentally ha-zardous consequences for life in cities. Currently, the Russian Federation has already developed criteria for information about natural and man-made emergencies; however, their effective and reasonable application is not possible due to an unreliable and un-clear assessment of the real impact of the event on the environment, as well as negative consequences for the natural environment and the life of the population under the influence of various factors, conditions, restrictions, taking into account cause-and-effect relationships. Such criteria have not been developed abroad in the format under study. The novelty of the approach proposed by the author lies in the development of scien-tifically based solutions and methods for the formation of a system of environmental criteria for emergency information, taking into account a risk-oriented preventive ap-proach to predicted adverse events. The competitive advantages of the work consist in solving a specific scientific and practical task of ensuring the effectiveness of the activi-ties of the Ministry of Emergency Situations of Russia in the field of ensuring the safe life of citizens in settlements. The purpose of the study was to update and improve methods, systems, technologies for forecasting and qualification of emergencies, to in-crease the level of validity and reliability of the criterion assessment of the attribution of events to emergencies and, as a consequence, the assessment of the safety of the urban environment. The proposed system is based on taking into account a complex of factors and parameters of environmental hazard, allows us to apply scientifically the criteria for the qualification of such events at the stages of the origin and occurrence of emergency situations (emergencies) with negative environmental consequences in settlements.

Published: August 2024

The article considers the methodology of generative design of urban infra-structure objects on the example of general educational institutions using ontology en-gineering. Generative design of urban infrastructure objects is an innovative approach to the creation of effective and optimal solutions in the field of urban planning. The proposed methodology initially defines the requirements and goals of facilities creation. Then the steps of developing an ontology model that describes the basic concepts such as object types, classes, territory and infrastructure, as well as the relationships between them are introduced. The normative documentation for the design of certain objects al-lows the creation of a strictly formalized model that reflects the current conditions and rules for the creation of urban infrastructure. At the final stage of the methodology, ge-nerative algorithms are introduced that allow to automate the design of new infrastruc-ture objects based on the specified parameters and rules from the ontological model. Such algorithms, for example, allow generating school building plans and the location of classrooms, taking into account the type of school and the number of students. The process of generative design of urban infrastructure objects using ontology engineering includes optimization and evaluation of the created solutions. The proposed methodol-ogy is an iterative process that allows to modify and improve models and algorithms based on the results and feedback. The case study of general education institutions con-sidered in the article demonstrates the effectiveness of such an approach, which takes into account various factors and constraints, and optimizes the use of resources and space

Published: August 2024

Nowadays, dietary fiber is no longer a modern food for teenagers in Indonesia. Dietary fiber has long been neglected as an important factor in dietary nutrition. This is due to a lack of public knowledge on the importance of consuming dietary fiber. Adolescence is a transition period from children to adult where they are easily influenced by the surrounding environment, easy to follow the latest trends where it is a determining factor for the quality of adolescents, such as the incidence of overweight in adolescents caused by lack of fiber consumption so that adolescents prefer fast food rather than fruit and vegetables. This study aims to determine the relationship between fiber consumption and the incidence of overweight in adolescent girls in Aceh Barat District. This research is a cross-sectional study with the sample of 50 adolescent girls aged 15-18 years old. Data was collected by means of a 24-hour food recall, weighing, and measuring their body height. Data analysis includes univariate and bivariate analysis with independent sample t-test. The results shows that there are 26% of adolescent girls who consume fiber well, while 76% of young women consume fiber bad. Fiber consumption affects the incidence of overweight in adolescent girls where the value of OR=13,588 (95% CI 1.591-116.032). So that fiber consumption has a 13.58 times chance of influencing adolescents girls not to be overweight.

Published: August 2024

Winged bean seeds are a source of vegetable protein and other important nutrients, and have the potential to be developed into ready-to-eat food to increase the level of consumption in society. The purpose of this study was to determine the effects of different levels of sterilization (F0) on the proximate composition of canned winged bean seeds. This study used a randomized block design (RBD) method with three levels of sterilization, F0 5, 7, and 9. The results showed that different levels of sterilization (F0 5, 7, and 9) had significant effects (P<0.05) on the moisture, carbohydrate, and protein content, but had no significant effect (P>0.05) on the ash and fat contents of sterilized winged bean seeds. The moisture and carbohydrate content increased as the F0 value increased. In contrast, protein levels of sterilized winged bean seeds decreased as the F0 value increased. Winged bean seeds sterilized with an F0 value of 9 had the highest levels of moisture and carbohydrates among the other two sterilization levels, but had the lowest protein content. The process of canning winged bean seeds using thermal sterilization is an alternative to maintaining the nutritional value of winged bean seeds. However, it still had a minimal effect on the nutritional content of winged bean seeds.

An essential aspect of food product development is the sensory evaluation of product characteristics to test consumer acceptance. Characteristic properties, such as color, texture, flavor, and aroma, significantly affect the perception and acceptance of consumers. This study aimed to determine the effect of adding various concentrations of Clitoria ternatea flower (CTF) extract to dadih jelly candy on the physical properties of color and sensory properties, especially on quality characteristics and levels of consumer acceptance, using a hedonic test. This study used an experimental randomized block design divided into five treatments with the addition of CTF extract at concentrations of 0%, 0.5%, 1%, 1.5%, and 2%. The results showed that the CTF extract had a significant effect on the level of brightness (L*), the hedonic quality of color, and the hedonic color test, but had no significant effect on the value of a* (redness), b* (yellowness), and the hedonic quality and hedonic test of texture, flavor, and aroma of dadih jelly candy. The addition of 0.5% CTF extract was characteristic of dadih jelly candy that the panelists liked the most. It has a slightly soft texture, slightly sweet flavor, slightly dadih aroma, and high brightness.

Moringa leaves (Moringa oleifera) is a vegetable plant from the Brassica order and belongs to the Moringaceae family, known as the “Magic Plant” which has a wide variety of protein content contained in it. Therefore, the bioactive compounds used are Moringa leaves (Moringa oleifera) which have such great potential that they can be developed as raw materials for medicine. However, because the secondary metabolite compounds contained by plants have hydrophobic properties. This property can be one of the obstacles for these secondary metabolites to be easily absorbed by the body because of their nature which is difficult to dissolve in body fluids so that they can be easily degraded by the body's enzymatic system, to overcome this problem Nanoparticles can be a solution in overcoming this problem. the manufacture of nanoparticles has been carried out. To produce nanoparticles of Moringa leaf bioactive compounds, synthesized using tween 80 surfactants, has been carried out using the spontaneous emulsion method. The bioactive compounds contained in Moringa leaves (Moringa oleifera) are: (1) 9-Octadecenoic acid (29.64%), (2) Hexadecanoic acid (18.42%), (3) Octadecanoic acid (7.07%), (4) Oleic Acid (5.88%), and (5) 14-Methyl-8-hexadesin-1-ol (5.47%). Synthesis using four different concentrate masses of these compounds, namely: 2 mg, 1.5 mg, 1 mg and 0.5 mg dissolved in 100 ml of ethanol, resulted in an average diameter of each nanoparticle of 15.9 nm; 15.5nm; 14.7nm; and 14.8 nm. The polydispersity index is 0.306; 0.258; 0.122; and 0.282. From the results above, it has been shown that the process of synthesizing nanoparticles of secondary metabolites of ethanol extract using the spontaneous emulsion method has produced small-sized particles. This allows the development of site results to be used in applications in various fields such as in the pharmaceutical field in the drug development process.

Living around the gold mining area, at risk of exposure to mercury (Hg). Pregnant women exposed to Hg alkyl can cause fetal brain damage so that the baby is born with d  efects. This is due to the target toxicity of Hg, especially the organic metal compounds are the nervous system. Based on a child development screening questionnaire, ±100 children were questioned about their development, motor development, language and social interaction. This research was to see a picture of the development of children living around the Gold Mining village of Kalirejo, Kokap district, Kulon Progo District, Yogyakarta.  The Longitudinal Observational Research Method with serial measurement measured the level of child development in five domains: cognitive, linguistic, motor, social, emotional and behavioral (adaptive behavior) with the Bayley Scale of Infant and Toddler Development Third Edition (BSID III) against 16 infants in the age range of 2-14 weeks (stage I) and 14-26 weeks. (tahap II). The baby's development observations resulted in an average composite development score of 85. Stage I obtained composite scores of cognitive domain; 102.81, language; 107.38, motor: 98.94, social emotional: 100,63 and behavioral: 90.00, while Stage II of each domain had the same scores as 105.94 : cognitive, 105.38: language, 104.81: motor, social-emotional: 98,69 and behavioural: 92.44. The conclusion that the composite child development score was in the average range of 90 - 109 for all domains, means that the child development composite score was still within the normal range (85-115), indicating that there is no developmental impediment. It is recommended to reduce Hg exposure, provide optimal nutrition to the baby and enhance developmental interventions with stimulation to stimulate auditorium, visual, tactile and kinesthetic, thereby improving the quantity and quality of brain cell synapses, to optimize brain function.

PT. Bridgestone Tire Indonesia is a tire manufacturing company. Machines that work continuously and lack of stock availability of machine spare parts cause damage and increase maintenance costs. To reduce the occurrence of damage and increase maintenance costs, it is necessary to have an optimal maintenance policy so that the machine can operate well. To overcome the problems in this research using the Reliability Centered Maintenance (RCM) method, the first step is determining the critical components on the machine, preparing the FMEA table based on the function data of the components and maintenance reports and calculating the Risk Priority Number (RPN), then calculating the MTTF and MTTR to determine maintenance and repair intervals and find optimal total maintenance costs. Machine building has the highest frequency of downtime so this research will focus on machine building components. The results of data processing show that the highest frequency of machine damage and total downtime is the cause of hose component failure due to poor hose quality and seal components becoming worn, causing increased frequency of damage, downtime and maintenance costs. Based on maintenance cost calculations using the RCM method, hose and seal components experienced a decrease in costs, namely hose components by 55.13% and seal components by 25.45%. The proposed building machine maintenance for hose and seal components in particular is to carry out scheduled tasks, scheduled exhaust tasks, and default actions with the task category of finding failures and results for maintenance time intervals for hose components of 280.81 hours and for seal components of 134.08 hours.

The palm oil processing system consists of several stages starting from receiving Fresh Fruit Bunches (FFB) to becoming palm oil or Crude Palm Oil (CPO). The palm oil processing process can be used in several stages carried out at each station. Based on interviews conducted, each station has a different level of risk of accidents, one of the stations that has a large risk of work accidents is the boiler station which is the heart of a palm oil factory where the steam boiler is the source of power and the source of the steam that will used to process palm oil. Boilers have potential dangers or risks when operated. The risks that often occur are falls, slips, burns, scalds, heat, noise, so it is very important to supervise and provide guidance regarding work safety. The size of the accident caused will certainly have a detrimental impact on the company. The severity of the accident can be determined through identification of potential dangers and risk assessment of all boiler operating activities at PT. Syaukath Agro. Based on the results of research conducted using the hirarc method, potential hazards found in boiler stations include: Unergonomic Working Attitudes, Noise Levels >84 dB with 8 Hours/Day Exposure, Working climate temperature (hot) 31°C on exposure >8 working hours/day, and oil buildup. Types of risk of work accidents at boiler stations consist of: Falls, injuries (slipping, slippery floors) Burns (in contact with hot objects around), Heat exhausting (Heat), Work accidents (fatigue ), hearing loss (noise), blisters (burns), health problems (muscles, bones), contact dermatitis (exposed to dangerous toxic radiation). Based on the results of risk control, it was found that the most appropriate type of control recommendation is administrative control and compliance with the use of personal protective equipment (PPE). Administration (Administration Control) is carried out by creating or providing a work system that can reduce the possibility of someone being exposed to potential dangers. The hierarchy of control of Personal Protective Equipment (PPE) is used to provide a boundary between exposure to the body and the potential danger received by the body.
