Abstract
In today’s world, information is one of the most important resources. Its large turnover in the media makes companies look for ways to automate processes related to labeling and storage of data. But often these processes are left on the shoulders of archive workers who have to review the footage in real-time and create metadata based on what they see, which will be transferred into the archive. This process is often very time-consuming. As a result of the analysis of approaches to video data processing, comparative analysis of the efficiency and availability of computer vision services, a software for searching faces, and forming metadata in the video archive of the VGTRK company was designed and implemented.

Published: October 2021

Abstract
The article discusses the possibilities for the development of automated processing of mammographic images based on the principles of a systematic approach. A structural diagram of an intelligent system for processing and analyzing mammographic images is proposed, which contains three main modules: a module for forming cascading windows, a module for combining cascading windows, and a module for classification and decision making. The software was developed in MATLAB 2018b environment. The possibilities of functioning of each module are considered. Experimental testing of the software of the intelligent system for the classification of breast radiographs according to the classes “no area of interest” or “area of interest” was carried out. A criterion for evaluating the results of classification of mammographic images is selected. Experiments on control samples showed diagnostic efficiency for the classes of radiographs “no region of interest” - “region of interest” not less than 90%.
Active tectonics of the Yogyakarta area (Central Java, Indonesia): preliminary findings obtained from a tectonic-geomorphic evaluation

Published: October 2021

AbstractThroughout the island of Java, several shallow faults located in the vicinity of densely populated areas accommodate the tectonic strain generated by the subduction of the Indo-Australian Plate beneath the Sunda Plate. These faults are characterized by a poor surface geomorphological expression due to the tropical climate that masks paleoseismological evidence making the identification of active faults in this environment challenging. We present preliminary data of a tectonic-geomorphic study that aims to identify and characterize active faults in the province of Yogyakarta (Central Java) as a basis to improve seismic hazard assessment. Here we focus on the Opak fault by describing its geomorphology and structure, using field data and remote sensing-based observations to contribute to the understanding of its geometry, kinematics, and tectonic activity. We show preliminary data supporting the Opak Fault as an active SW-NE transtensional left-lateral strike-slip reactivated normal fault consisting of several parallel fault strands. Although geomorphological expression of active tectonics is poor and diffuse, we found numerous field evidence of active tectonics ranging from tilted Quaternary fluvial terrace risers, triangular facets, and linear valleys to peculiar drainage patterns that allow us to provide evidence of the Holocene activity of the Opak Fault.

Abstract
Indonesia is a country located at the meeting of three tectonic plates. This condition makes Indonesia a disaster-prone region, especially caused by the movement of tectonic plates, one of which is the tsunami. Several tsunami occurs were recorded in Indonesia. Tsunami occur on a large scale and causes losses, both environmental damage and fatalities. Therefore, evacuation planning is needed to minimize the number of fatalities when a tsunami occurs. This study aims to find out the potential threat of tsunami hazard in Ciletuh Bay and analyze evacuation planning in the region. The method used in this research is the spatial modeling method which is divided into tsunami inundation modeling, population distribution, and estimated evacuation travel time. The result of this study is that potential tsunami hazard in Ciwaru Village id found in two hamlets with an area of 104.63 Ha. A total of 590 exposed residents can evacuate within 0 – 15 minutes. The selection of evacuation routes with the fastest travel time is needed so that residents can reach the evacuation collection point before the tsunami arrives. The availability of road access in the hamlet makes it easier for residents in tsunami-exposed areas to reach evacuation gathering points.

Published: October 2021

Abstract
Sufficient water supply can still be a big challenge in developing countries. A large number of households in Yogyakarta still relay on private dug wells to meet their daily demand. But water from shallow aquifers is prone to pollution from sewage systems, industry and agriculture. To assess the water quality in the basin of Yogyakarta, this study determines the chemical characteristics of the shallow groundwater in anthropogenically influenced and uninfluenced areas in and around the city of Yogyakarta. Therefore, a combination of on-site and laboratory analysis is used to distinguish areas of different water types. The observations give a major ion distribution for the whole research area and show significant anomalies in nitrate and phosphate concentrations especially in the city. Furthermore, high DOC values point out that the aquifer is widely polluted. There is a need for a better groundwater protection and remediation strategy to facilitate future use of those groundwaters.

Published: October 2021

Abstract
A geophysical survey using broadband magnetotelluric (MT) technology was carried out in Suwawa Geothermal Prospect Area, Gorontalo Province, Sulawesi Island, Indonesia. The target of that research is to evaluate the geothermal potential hidden below the surface, based on underground resistivity distribution. However, the information about resistivity alone is not enough to get a proper understanding of the geothermal system in this area. Another important subsurface feature that could be useful for the evaluation is temperature. In this study, an attempt to predict the subsurface temperature using resistivity and limited information from a shallow borehole thermogram was carried out. Employing the dependency between resistivity and temperature an indirect temperature estimator was built, thanks to the applicability of artificial neural network (ANN) to learn the pattern connecting both parameters. Comparing some neural network training data shows that the predictive powers of the calibrated neural network highly influenced by the geological difference between the location of borehole and MT station. The best trained ANN was then used to predict the temperature below the other MT stations. The result shows that a proper ANN architecture is important to improve the deeper temperature estimation. The best ANN estimator was obtained from the BT01 and AMT39 data pair, which has the highest correlation as well. This preliminary study gives useful insight into how resistivity could be an alternative tool to delineate the near-surface temperature profile, in order to get a more comprehensive image of the subsurface geothermal system.

Abstract
Debris avalanche deposit is formed by the failure of volcanic edifice and has a high potential to directly impact human civilization. The famous characteristic landform of debris avalanche deposit is hummocky hills. To understand the dynamics of avalanche flow, we investigate the morphometric characters of debris avalanche hummocks from Gunung Gadung in Raung Volcanic Complex. The collapse of Gunung Gadung follows two main flow direction with two different kinds of debris avalanche, i.e., freely spreading and valley filling. Our study recorded that there is no significant correlation between hummock size and distance from the source. The distribution of Gadung hummock size is mainly controlled by pre-existing morphologic feature such as Iyang-Argapura Volcanic Complex and Meru Betiri Mountains. We identify four domains area of Gadung debris avalanche flow based on hummock size distribution, which are Toreva domain, Hummock domain, Collision domain, and Oblique collision domain. Hummock orientation and displacement angle of Gadung debris avalanche deposit depend on structural regime existed in certain area. Compressional regime may occur because of collision between Gadung avalanche flow and Iyang-Argapura Volcanic Complex, or shifting of main flow direction. Meanwhile, extensional regime may happen due to decreasing in slope and spreading of avalanche flow.

Abstract
We present the first finding of skarn rocks in Cemorosewu area of East Jiwo Hill, Bayat, Central Java, Indonesia. The geological conditions of this area which related to the appearance of the skarn is also reported. The methods used in this research are DEM acquisition using drone to generate basemap for geological mapping and thin section petrographic analyses. The geological map shows that Cemorosewu area consists of metamorphic rocks (mica phyllite, graphite phyllite, with quartzite and marble lenses), sedimentary rocks (carbonate breccia and siltstone), and igneous rock (microdiorite). Based on the field observation and geological map, the regional metamorphic rocks are the oldest units in this area followed by sedimentary rocks and igneous rock which intruded both rocks. Skarn rocks were cropped out as a boulder along the Kluwihan creek with the maximum size of 8 m in length. The skarn consists of garnet, clinopyroxene, zoisite, actinolite, and minor quartz. Metasiltstone and skarn rock are suggested formed by contact metamorphism of microdiorite intrusion. The marble, which lenses within the phyllites, is suggested to be the protolith of the skarn formation in this area.
Need for system of protection against floods and high waters in mountain and foothill rivers of the Caucasus

Published: October 2021

Abstract
The article presents findings on the estimation of fast-forming floods parameters and hydrological forecasts for short-term changes in water content in the foothill and mountain rivers of southern Russia as exemplified by the Krasnodar Krai. The research aims to provide economic facilities and population with better protection against rapidly forming mixed-origin floods. The need to develop a system of protection against floods and high waters on the mountain and foothill rivers of the Caucasus are considered. The floods in the Tuapse region in October 2010, Krymsk in July 2012, Novomikhaylovsky in August 2012 are taken as an example. The causes of floods and high waters on rivers are different. Precipitation is the main and dominant source of floods and high waters (exclusive of natural and anthropogenic discharge breakthrough floods) in river basins. The North-West Caucasus territory and especially its Black Sea coast is distinguished by rain floods at any time of the year. The main reason for floods is rainfall with an intensity of minimum 50-100 mm/day. Considering that 1 mm of precipitation causes the fallout of 1 liter of water over 1 m2 of the earth’s surface, this amount of precipitation is equivalent to the flow of 50-100 liters of water per 1 m2 of mountain slopes. The surface of the slopes cannot immediately absorb and hold such an amount of water, and it rushes down into the rivers’ and streams’ beds. An increase in water content leads to a sharp rise in the water level and flooding of the territories adjacent to the river.

Published: October 2021

Abstract
The article presents the results of studies on the effect of the antioxidant beta-carotene and storage temperature on hydrolytic and oxidative processes occurring during storage of extra virgin olive oil obtained from olives grown in the soil and climatic conditions in Syria. The research aims to study the effect of temperature and beta-carotene on the kinetics of the hydrolysis reactions of triglycerides and fatty acids oxidation in olive oil during storage. The object of the study was extra virgin olive oil obtained from olives grown in Syria according to the generally accepted technology in 2019. And beta-carotene, produced by Ekoresurs, has been used as a natural antioxidant. The kinetics of the hydrolysis and oxidation reaction was evaluated by studying the change in the content of saturated and unsaturated fatty acids during storage of the control sample from olive oil (sample No. 1), and experimental samples with the addition of beta-carotene at concentrations of 400 mg/L (sample No. 2) and 600 mg/L (sample No. 3). These samples were stored at 18 ° C. And sample No. 4 was stored without adding beta-carotene at 4 ° C. Upon receipt for storage and during this process, the content of saturated and unsaturated fatty acids in the test samples was determined periodically by gas chromatography on an LC-20 Shimadzu chromatograph, and organoleptic quality indicators were evaluated on a five-point scale. In addition, the content of triacylglycerols, saturated and unsaturated fatty acids were determined based on the change in beta-carotene dose, temperature, and period of storage. Also, the rate constants of the fatty acid oxidation reaction have been calculated. It was shown that the minimum rate of free fatty acids oxidation during storage of extra virgin olive oil for 7 months was in the olive oil sample stored at + 18 ° C with the addition of 400 mg/L of beta-carotene, as well as in the olive oil sample stored in the refrigerator at + 4 ° C without adding antioxidant.

Abstract
The technology for the rational use of collagen-containing waste, namely the skin from cutting slightly salted herring, is presented. The technology for obtaining oil containing polyunsaturated fatty acids and collagen hydrolyzate from by-products of production of preserves from slightly salted herring was developed. The rational parameters of hydrolysis in gentle conditions using electrochemically obtained catholytes have been determined and substantiated, which ensures waste-free processing of raw materials and the reduction of oxidized nutrients. The cryoconcentration method was used to concentrate essential acids. We studied the phase transitions of the obtained lipids in the temperature range from + 15 ° C to minus 40 ° C in a calcium chloride environment using a low-temperature refrigeration unit. The properties of 5 lipid fractions formed during lipid phase transitions have been identified and studied. The technology was applied to fatty raw materials - skin from cutting slightly salted herring into fillets. The physical and chemical properties of raw materials and finished products have been investigated. The mass yields of fish oil and collagen hydrolyzate have been determined. Comparative analysis of fatty acid composition of fish skin before and after electrochemical treatment has been carried out.

Published: October 2021

Abstract
Currently, the issues of improving the heat transfer processes in air-cooled heat exchangers play a huge role in terms of increasing the cooling efficiency and thus reducing the size of heat exchangers. This significantly saves resources. There are several basic methods for increasing the heat transfer of fluids in air coolers, for example, such as: finning of tubes and heat exchange intensification with the help of tube inserts. The purpose of the study is to analyze the efficiency of different fin types and the use of tube inserts, as well as changes in the heat transfer coefficients of air and natural gas, depending on the changes in the types of fins and tube inserts, and their geometry. The application software is Xchanger Suite provided by the company HTRI to ITMO University. The result is the optimally selected geometry of the heat exchange intensifiers based on the analysis, what allows reducing the dimensions of the air- cooled heat exchangers, while providing the necessary heat load, the heat exchange surface reserve coefficient and the heat transfer coefficients.

Abstract
The refrigeration, air-conditioning and heat pumping industries are essential sectors of the world economy. The list of the major synthetic refrigerants characterized by the non-flammability, low toxicity, good thermophysical properties and stability are reviewed. The HCFCs and fully halogenated CFCs refrigerants are responsible for the destruction of stratospheric ozone. The paper details the effects of two allergens – the global climate change and the depletion of stratospheric ozone due to chlorofluorocarbons, hydrochlorofluorocarbons and hydrofluorocarbons. This situation has been estimated as sufficient to cause alarm. The urgent task today is to develop harmless refrigerants with zero ozone depletion potential and a minimal greenhouse effect potential.

Published: October 2021

Abstract
The paper analyzes the geological and physical characteristics of the White Tiger field, deep and estuary samples of oil and asphaltene-resin-paraffin (ARP) deposits, which revealed the main factors leading to the intensive accumulation of asphaltenes on tubing surface during oil production. First of all, these are high formation temperatures (80-120°C) in combination with high paraffin separation temperature (57°C) and a relatively large oil depth (up to 4,500 m). Experimental studies were carried out and chemical reagents consisting of a mixture of polyvinyl acetate and organic solvents were selected (naphthalene, toluene, aromatic derivatives), which affect paraffin separation, which, in turn, leads to a decrease in viscosity and dynamic shear stress at the same temperature, as well as a decrease in oil congelation temperature thereby promoting the inhibition of asphaltene-resin-paraffin deposits by interacting with an activator for gel formation, adsorption on the surface of rocks, i.e. preventing the formation of asphaltene during oil production.

Abstract
For the purpose of using the residual or wasted heat, many scientists are currently conducting research on the possibility of using the wasted heat. At the same time, an active search is underway for new materials and new technologies that will improve the characteristics to increase ecological efficiency of the thermal module and heat accumulator. To guarantee the transition to environmentally friendly energy when searching for or creating new materials and technologies, it is necessary to conduct an environmental analysis and confirm the safety of materials for the environment based on a life cycle assessment. Without a life cycle assessment, the claim that a product or service is safe for the environment will be unfounded. In addition, the transfer of the environmental load to the stage of obtaining materials can lead to the fact that the use of new energy converters will be much more dangerous and less efficient in terms of consumed natural resources than not using “lost” heat. In this regard, before introducing into mass production, it is advisable to analyze the life cycle of a new material (prototype) with obtaining confirmation of safety for the environment, which was done in this work. Based on the obtained results conclusions were drawn about the advisability of using auxiliary technologies that increase the energy efficiency of a traditional thermal installation.
