Abstract. The pH of coastal seawater varies based on several local forcings, such as water circulation, terrestrial inputs, and biological processes, and these forcings can change along with global climate change. Understanding the mechanism of pH variation in each coastal area is thus important for a realistic future projection that considers changes in these forcings. From 2020 to 2021, we performed parallel year-round observations of pH and related ocean parameters at five stations around the Japanese coast (Miyako Bay, Shizugawa Bay, Kashiwazaki Coast, Hinase Archipelago, and Ohno Strait) to understand the characteristics of short-term pH variations and their forcings. Annual variability (~1 standard deviation) of pH and aragonite saturation state (Ωara) were 0.05–0.09 and 0.25–0.29, respectively, for three areas with low anthropogenic loadings (Miyako Bay, Kashiwazaki Coast, and Shizugawa Bay), while it increased to 0.16–0.21 and 0.52–0.58, respectively, in two areas with medium anthropogenic loadings (Hinase Archipelago and Ohno Strait in Seto Inland Sea). Statistical assessment of temporal variability at various timescales revealed that most of the annual variabilities in both pH and Ωara were derived by short-term variation at a timescale of < 10 days, rather than seasonal-scale variation. Our analyses further illustrated that most of the short-term pH variation was caused by biological processes, while both thermodynamic and biological processes equally contributed to the temporal variation in Ωara. The observed results showed that short-term acidification with Ωara < 1.5 occurred occasionally in Miyako and Shizugawa Bays, while it occurred frequently in the Hinase Archipelago and Ohno Strait. Most of such short-term acidified events were related to short-term low-salinity events. Our analyses showed that the amplitude of short-term pH variation was linearly correlated with that of short-term salinity variation, and its regression coefficient at the time of high freshwater input was positively correlated with the nutrient concentration of the main river that flows into the coastal area.

Published: May 2023

Abstract. The paper considers the problem of identifying game events in a video game of beach volleyball. As a method for solving the problem, a combined approach is proposed based on recognizing the trajectory of the ball and constructing skeletal representations of the players. Temporal localization of game events is carried out by searching for the changes in the ball trajectory using the construction of a composite Bezier curve. Spatial localization is performed by the positioning of the ball and the players in the frame at the moment of the trajectory change. The classification is based on the skeletal representation of the player touching the ball. The experiments performed show that the algorithm is able to perform spatiotemporal localization with high precision and recall.
MULTIMODAL PERSON RE-IDENTIFICATION IN AERIAL IMAGERY BASED ON CONDITIONAL ADVERSARIAL NETWORKS

Published: May 2023

Abstract. Person Re-Identification (Re-ID) is the task of matching the same person in multiple images captured by different cameras. Recently deep learning-based Re-ID algorithms demonstrated an exciting progress for terrestrial-based cameras, still, person Re-ID in aerial images poses multiple challenges including occlusion of human feature parts, image distortion, and dynamic camera location. In this paper, we propose a new Person Aerial Re-ID framework Robust to Occlusion and Thermal imagery (ParrotGAN). Our model is focused on cross-modality person Re-ID in aerial images. Furthermore, we collected a new large-scale synthetic multimodal AerialReID dataset with 30k images and 137 person ID. Our ParrotGAN model leverages two strategies to achieve robust performance in the task of person Re-ID in thermal and visible range. Firstly, we use a latent space of StyleGAN2 model to estimate the distance between two images of a person. Specifically, we project each real image into the latent space with a correspondent latent vector z. We use the distance between latent vectors to provide a Re-ID similarity metric. Secondly, we use a generative-adversarial network to translate a color image to a synthetic thermal image. We use synthetic image for a cross-modality Re-ID. We evaluate our ParrotGAN model and basleines on our AerialReID and PRAI-1581 datasets. The results of the evaluation are encouraging and demonstrate that our ParrotGAN model competes with baselines in visible range aerial person Re-ID and outperforms them in the cross-modality setting. We made our code and dataset publicly available.

Published: May 2023

Abstract. One of the most dangerous complications during brain surgery is bleeding. Hemostasis can be difficult due to the lack of visibility caused by blood filling the surgical wound. To restore the visibility of the surgical area it is proposed to use NIR-camera data and Shearlet transform with color-coding algorithms. At the same time it is also assumed to conduct brightness characteristics enhancement of images (frames) and segmentation of biological tissues of interest. NIR beams are able to penetrate deeper into tissues than visible light and NIR is also absorbed to a greater extent by hemoglobin than by surrounding tissues. The blood has a significantly higher absorption coefficient of NIR rays in the range from 800 nm to 1050 nm in comparison with the absorption coefficient of the same spectrum by the tissues involved during the operation. Due to this effect there is the potential to detect structures of interest despite bleeding in the wound cavity. During experimental study it was found that it becomes possible to visualize all tissues that are at a depth of up to 3 mm. Use of BCET algorithm with the mask for processing made it possible to improve the image contrast from 34.20% to 198.73% depending on the depth of biological structures. In case of model images processing the best average accuracy of determining ROI contours taking into account depth was 0.961 ± 0.021 according Dice similarity coefficient.
AN ALGORITHM FOR AUTOMATED DETECTION OF DELAYED BRAIN ISCHEMIA INDICATOR FROM VIDEO-EEG MONITORING DATA
Authors: Murashov D. , Obukhov Y. , Kershner I. , Sinkin M.
Published: May 2023

Abstract. In this work, we propose a new algorithm for detecting the indicator of delayed cerebral ischemia from video-EEG monitoring data. The proposed algorithm combines an algorithm for detecting the effect of interchannel time-frequency synchronization of wavelet spectrogram ridges of EEG signals and an algorithm for detecting motion artifacts in video recording frames. Using the EEG analysis algorithm, we identify an indicator that is used to predict the occurrence of ischemia. By analyzing the optical flow, we exclude time intervals in which erroneous fixation of ischemia indicators is possible. The developed algorithm was tested on the clinical data of video-EEG monitoring. The preliminary results obtained during testing confirm the fundamental possibility of detecting the ischemia indicators and the acceptable accuracy of detecting motion artifacts leading to an erroneous diagnosis.

ADAPTIVE ILLUMINATION CORRECTION ALGORITHM BASED ON RETINEX TECHNOLOGY FOR CAMERA TRAP IMAGES
Authors: Zotin A. G. , Proskurin A. V.
Published: May 2023

Abstract. Camera traps generating a huge number of images help to study and monitor the wildlife. However, camera traps work at any time of the day and under any weather conditions. Therefore, many images have low or high illumination, blurring, and other defects. This complicates image analysis by both humans and computer systems. In this study, we develop an adaptive illumination correction algorithm based on a modified Multi-Scale Retinex (MSR). First, we accelerate computation by using recursive implementation of the Gaussian filter and utilizing look-up tables to find logarithms and new brightness values. Second, response of the MSR function is transformed by a modified threshold normalization to improve image quality. The upper and lower thresholds are calculated based on statistical information. Finally, we offer automatic adjustment of parameters depending on the area of the image in order to increase usability. Proposed algorithm was tested with various settings on a set of images obtained from camera traps. Experimental results show a high potential for its application.
CASE STUDY FOR UAS-ASSISTED BRIDGE INSPECTIONS
Authors: Bartczak E. T. , Bassier M. , Vergauwen M.
Published: May 2023

Abstract. Bridge inspections are typically expensive and time-consuming, especially in regards of the inspection of difficult-to-reach areas. In recent years, unmanned aerial systems (UASs) have gained attention due to their flexible data acquisition. However, UAS inspections generate large quantities of image and video data, which are currently analysed manually. Additionally, identified damages are currently not assessed accurately in their geometric characteristics and location. In this paper, we propose a time-effective framework for a UAS-based bridge inspection methodology that combines 3D information from photogrammetry and machine learning based object detection to allow direct measurements in the images. Concretely, we propose the use of a two-step flight planning to accurately reconstruct the bridge using limited manual effort. Second, we detect frequently occurring damages such as exposed rebars and concrete spalling on the inspection imagery. Finally, we use the spatial location of the imagery to significantly improve the detection results and geolocate them. We evaluate our proposed framework on a decommissioned concrete bridge. The trained YOLOv8 models prove capable of transfer learning on both our own data and online benchmarks. The photogrammetric reconstruction also proves to be sufficiently reliable. Overall, these are the first steps in automating routine bridge inspections and provide crucial evidence to continue developing the method.

Authors: Filin A. , Kopylov A. , Gracheva I.
Published: May 2023

Abstract. Benchmarking of haze removal methods and training related models requires appropriate datasets. The most objective metrics of assessment quality of dehazing are shown by reference metrics – i.e. those in which the reconstructed image is compared with the reference (ground-truth) image without haze. The dehazing datasets consist of pairs where haze is artificially synthesized on ground-truth images are not well suited for the assessment of the quality of dehazing methods. Accommodation of the real-world environment for take truthful pairs of hazy and haze-free images are difficult, so there are few image dehazing datasets, which consists with the real both hazy and haze-free images. The currently researcher’s attention is shifting to dehazing on “more complex” images, including those that are obtained in insufficient illumination conditions and with the presence of localized light sources. It is almost no datasets with such pairs of images, which makes it difficult of objective assessment of image dehazing methods. In this paper, we present extended version of our previously proposed dataset of this kind with more haze density levels and depths of scenes. It consists of images of 2 scenes at 4 lighting and 8 haze density levels – 64 frames in total. In addition to images in the visible spectrum, for each frame depth map and thermal image was captured. An experimental evaluation of state-of-the art haze removal methods was carried out on the resulting dataset.

Clustering of eruptive events from high-precision strain signals recorded during the 2020–2022 lava fountains at the Etna volcano (Italy)
Authors: Carleo Luigi , Currenti Gilda , Bonaccorso Alessandro
Published: May 2023

Abstract. Lava fountains at the Etna volcano are spectacular eruptive events characterized by powerful jets that expel hot mixtures of solid particles and volcanic gases, easily reaching stratospheric heights. Ash dispersal and fallout of solid particles affect the inhabited areas, often causing hazards both to infrastructure and to air and vehicular traffic. We focus on the extraordinary intense and frequent eruptive activity at Etna in the period of December 2020–February 2022, when more than 60 lava fountain events occurred with various ejected magma volume and lava fountain height and
duration. Differences among the events are also imprinted in tiny ground
deformations caught by strain signals recorded concurrently with the lava
fountain events, reflecting a strict relationship with their evolution. To
characterize this variability, which denotes changes in the eruption style,
we clustered the lava fountain events using the k-means algorithm applied on the strain signal. A novel procedure was developed to ensure a high-quality clustering process and obtain robust results. The analysis identified four groups of strain variations which stand out for their amplitude, duration and time derivative of the signal. The temporal distribution of the clusters
highlighted a transition in different types of eruptions, thus revealing
the importance of clustering the strain variations for monitoring the
volcano activity and evaluating the associated hazards.

Published: May 2023

Abstract. Over the last 2 decades, the topic of
earthquake-triggered landslides (EQTLs) has shown increasing relevance in
the scientific community. This interest is confirmed by the numerous
articles published in international, peer-reviewed journals. In this
work we present a database containing a selection of articles published on
this topic from 1984 to 2021. The articles were selected through a
systematic search on the Clarivate™ Web of Science™ Core
Collection online platform and were catalogued into a web-based GIS (web-GIS),
which was specifically designed to show different types of information.
After a general analysis of the database, for each article the following aspects were identified:
the bibliometric information (e.g. author(s), title, publication year), the
relevant topic and sub-topic category (or categories), and the earthquake(s) addressed. The
analysis allowed us to infer general information and statistics on EQTLs (e.g.
relevant methodological approaches over time and in relation to the scale of
investigation, most studied events), which can be useful to obtain a spatial
distribution of the articles and a general overview of the topic.
Brief communication: Non-linear sensitivity of glacier mass balance to climate attested by temperature-index models
Authors: Vincent Christian , Thibert Emmanuel
Published: May 2023

Abstract. Temperature-index models have been widely used for glacier-mass projections
spanning the 21st century. The ability of temperature-index models to
capture non-linear responses of glacier surface mass balance (SMB) to high deviations in air temperature and solid precipitation was recently discussed in the context of mass-balance simulations employing advanced
machine-learning techniques. Here, we performed numerical experiments with a
classic temperature-index model and confirmed that such models are capable
of detecting non-linear responses of glacier SMB to temperature and precipitation changes. Non-linearities derive from the change in the degree-day factor over the ablation season and from the lengthening of the
ablation season.

Published: May 2023

Abstract. Lake ice melting and breakup form a fast, nonlinear process with
important mechanical, chemical, and biological consequences. The process is
difficult to study in the field due to safety issues, and therefore only
little is known about its details. In the present work, the field data were
collected on foot, by hydrocopter, and by boat for a full time series of the
evolution of ice thickness, structure, and geochemistry through the melting
period. The observations were made in lake Pääjärvi in 2018
(pilot study) and 2022. In 2022, the maximum thickness of ice was 55 cm with
60 % snow ice, and in 40 d the ice melted by 33 cm from the surface
and 22 cm from the bottom while the porosity increased from less than 5 %
to 40 %–50 % at breakup. In 2018, the snow-ice layer was thin, and bottom
and internal melting dominated the ice decay. The mean melting rates were
1.31 cm d−1 in 2022 and 1.55 cm d−1 in 2018. In 2022 the
electrical conductivity (EC) of ice was 11.4 ± 5.79 µS cm−1, which is
1 order of magnitude lower than in the lake water, and ice pH was 6.44 ± 0.28, which is lower by 0.4 than in water. The pH and EC of ice and water
decreased during the ice decay except for slight increases in ice due to
flushing by lake water. Chlorophyll a was less than 0.5 µg L−1 in
porous ice, approximately one-third of that in the lake water. The results
are important for understanding the process of ice decay with consequences
for lake ecology, further development of numerical lake ice models, and
modeling the safety of ice cover and ice loads.
Were COVID pedestrian streets good for business? Evidence from interviews and surveys from across the US
Authors: Andersen Hayden , Fitch Dillon , Handy Susan
Published: May 2023

During the COVID pandemic, at least 97 US cities closed downtown streets to vehicles to create commercial pedestrian streets with the goal of encouraging active travel and economic activity at safe social distances. This study addressed three questions about these programs for businesses located on a pedestrian street: 1) what factors influenced their feelings about the program; 2) what concerns did businesses located on pedestrian streets have; and 3) how did the pedestrian street program impact a business’s revenue as compared to other businesses in the area on streets that did not close. We created a geographic database of these pedestrian streets and identified nearly 14,000 abutting businesses, from which we collected interview and survey data. The interviews and survey results highlight key issues surrounding businesses’ experiences with pedestrian streets. Businesses abutting pedestrian streets had a slightly higher opinion of these programs than businesses not abutting these streets. A test of the effect of pedestrian street interventions on business revenue using a pseudo-control group showed the effect to be uncertain but, on average, negligible. The findings point to steps that cities can take to maximize the benefits of pedestrian streets for local businesses.

Exploring the Action of Homoeopathic Constitutional Medicines in Rhinosinusitis in Age Group 18 to 55 years – An Experimental Study
Authors: Kharbuli Bethshida , Papiah Sammaia
Published: May 2023

Introduction: Rhinosinusitis is one of the most common chronic diseases with a high prevalence seen in everyday life. It is a condition which is characterized by inflammation of the nasal mucosa and paranasal sinuses. The presenting symptoms include episodes of pain in the face and affections of any sinus i.e., frontal, maxillary, ethmoidal which are frequently seen along with nasal obstruction, nasal discharge, polypoidal changes. Frequent tendencies to rhinosinusitis can best be treated with homoeopathic approach of individualistic treatment that is with constitutional medicines.
Materials and Method: An experimental study was conducted with a sample size of 30 fulfilling the inclusion and exclusion criteria. The sample size was chosen by simple sampling method and patients selected fulfilled the diagnostic criteria of rhinosinusitis. With every follow up, symptoms severity was evaluated using a self-designed assessment scale for disease severity. Pre-treatment assessment score and post-treatment assessment score of each follow up was compared to assess the overall improvement in the patient. The alternative hypothesis was accepted using the Wilcoxon signed rank test.
Results: Wilcoxon Signed Rank test shows that the significance value is 0.000. Since the significance value < P value 0.05, the difference between two scores is statistically significant. It can be then concluded that difference between pre-treatment score and post-treatment score is significant and hence we reject the null hypothesis and proves the action of constitutional homoeopathic medicines in treating rhinosinusitis.
Conclusion: Constitutional homoeopathic medicines are effective in treating cases of rhinosinusitis.

Comparative Study between Indigenously Developed Multi-Axis Prosthetic Foot and SACH Foot in Terms of Gait Parameters and Energy Expenditure in the Patients with Unilateral Transtibial Amputation
Authors: R. Thakre Devidas , Kumar Tiwari Manoj , P. Prabhu Deepak
Published: May 2023

Background: There are a large number of commercially available, prosthetic feet. Properly selecting prosthetic foot-ankle components with appropriate design characteristics is critical for successful amputee rehabilitation. However, currently developed prosthetic foot designs are high performance, dynamic response, energy restoring, and multi-axial motion properties. These are all made from carbon composite material, with superior strength and weight ratio. In fitting an artificial limb, the goal of the prosthetist is to restore the ability of the amputee to perform everyday activities in an easy, natural, and comfortable manner, all prosthetic foot attempt to return some of the lost gait function. But for the average individual in a developing country like India, amputees cannot afford such types of feet, which are more expensive. There is a need for a new prosthetic foot in economically developing countries that is technically simple yet functionally more equivalent to a dynamic response foot. The new design of a multi-axial prosthetic foot has been developed in this study, mechanically tested with 5000 cycles, and its effectiveness is compared with a time-tested SACH foot. The multi-axial prosthetic foot is the most effective and significant prosthetic foot design. The anatomical foot has multi-axial motion property, which is cautiously accommodated in this design characteristics deemed necessary by patients in achieving natural gait motion, including dorsiflexion, plantarflexion, inversion, and eversion mimics biomechanical characteristics of the prosthetic foot.
Study Design: Experimental interventional prospective study
Objective: To design and develop a multi-axis prosthetic foot that allows the same triplanar motion as a normal human ankle and foot and compare its effectiveness with the SACH foot in terms of gait parameters and energy expenditure by calculating the Physiological Cost Index.
Methods: 30 participants with unilateral transtibial amputation were recruited randomly and evaluated with SACH foot and multi-axial foot. The primary outcomes were gait parameters and energy expenditure.
Results: The multi-axial prosthetic foot has to be found to be more efficient than the SACH foot; at the p<0.05, there was a significant difference in the patient’s gait parameters and energy expenditure.
Conclusion: Multi-axial prosthetic foot improved patient’s gait as they covered more distance than SACH foot while walking on level ground. A newly designed multi-axis prosthetic foot mimics the normal human anatomical ankle. It helps to increase step length, stride length, cadence, and speed; hence subjects walk more efficiently with less energy consumption.

O modo de fazer política numa cidade do interior da Paraíba: entraves à política pública a partir da lógica dos favores.
Authors:   , Maria Antonino Brito Tereza
Published: May 2023

O presente trabalho tem por objetivo estabelecer a relação entre política pública e a cultura da dádiva da qual as relações são mediadas pelas trocas de favores, tendo como lócus de pesquisa o município de Serra Branca. A questão que nos conduziu a realizar essa pesquisa foi: De que forma a cultura da dádiva inibe a construção de políticas públicas? A nossa hipótese é a de que a lógica da dádiva se fundamenta nas relações sociais pautadas pela pessoalidade, enquanto que a política pública relaciona-se ao princípio da impessoalidade. Em termos metodológicos, foi realizado levantamento bibliográfico e trabalho de campo, bem como observação participante com anotações no Diário de Campo e entrevistas previamente elaboradas acerca de algumas questões que dizem respeito à temática. As questões foram aplicadas a 12 pessoas que trabalham ou trabalharam no espaço da prefeitura e no legislativo municipal, bem como as pessoas que recebem “ajudas” do poder público de Serra Branca. O estudo pode contribuir para uma nova percepção acerca das políticas públicas, percebendo os principais entraves a partir da lógica cultural que legitima práticas de violências simbólicas e de profundas desigualdades, as quais são aparentemente resolvidas através das “ajudas”.
A Análise do processo de execução fiscal do IPTU na cidade de Sumé - PB.
Authors:   , Mendonça de Lima Evandro
Published: May 2023

O IPTU é considerado um imposto importante na receita tributária dos municípios, onde a arrecadação contribui para custear as despesas da administração pública, os serviços básicos de infraestrutura e outros serviços sociais. O não pagamento desse imposto causa prejuízo a toda a população, dificultando administração de despenhar as melhorias para o município. Neste sentido esse trabalho se propôs verificar as taxas de inadimplência no Município de Sumé-Pb, tomando como base os anos 2007 a 2012 e identificar os fatores que dificulta o processo de execução fiscal do IPTU. A metodologia aplicada foi bibliográfica e descritiva; na bibliográfica utilizou-se de livros e artigos publicados na internet, abordando autores do direito tributário buscando explicar as normas do Código Tributário Nacional (CTN), completado com a pesquisa de campo através de coletas de dados fornecidos pela prefeitura pôde-se formular tabelas e fazer um diagnóstico da situação do processo de execução fiscal do IPTU . Foi possível identificar a deficiência do setor de tributos junto com a secretaria de finanças do município, no que diz respeito a execução judicial dos débitos atrasados dos contribuintes inadimplentes do IPTU, e com uma entrevista feita através de questionário com o chefe de tributos da prefeitura de Sumé chegou-se ao resultado de que os fatores políticos interferem na cobrança do IPTU, na medida em que a prefeitura a deixa de executar os contribuintes inadimplentes. Espera-se que o estudo venha servir de alerta a administração pública de Sumé.

Despite the interesting structure of the generic thiacalix[4]arene containing four coordinating sulfur atoms bridging four phenolic units, there are only a few reported examples of thiacalixarene-based coordination complexes that are used as electrocatalysts. Herein, we report electrocatalytic hydrogen evolution reaction (HER) by a thiacalix[4]arene-based copper(II) complex (1). As expected, two reduction waves were appeared (-0.48 V and -1.30 V vs Ag/AgCl) for Cu2+/Cu+ and Cu+/Cu reduction couples. The HER by proton reduction occurs at -1.03 V with a shift of 0.27 V compared to the second peak potential at -1.30 V. The increase in the number of acetic acid equivalents, from 0 to 17.5 with a frequency of 2.5 eq, was accompanied by an increase in the peak current that reached a maximum value of 183 and#181;A for 15 equivalents of acetic acid.

A model of the physical properties and structure changes inside the gap between the swcnt and surface is proposed. The swcnt was viewed in the model as anode, the surface as cathode, and the gap between them as the time-changed homogeneous media. The electrical erosion occurs in this gap according to probabilistic nature. The aim of the paper was to propose the model to stimulate particle emissions from the gap, namely, to ejects particles from the space to prevent electrical corrosion. This stochastic model investigates the stream of the micro- and nanosized particles generated and detached from the surfaces of the anode and the cathode considering the movement of the particle flow, orientation of the gap in space, and the stream density change. The result demonstrates the impact of the orientation angle of the space on the parameters of the erosion particle flow. The findings are in a good agreement with the experimental studies of many investigations.

Published: May 2023

The influence of microwave heating of liquids in a microreactor using beam-type source on the intensity of the current chemical process is considered. It is shown that а non-uniform heating of the reagents over the microreactor length stimulates the development of the thermal capillary convection phenomenon and substantially accelerates the chemical process. A numerical evaluation of maximal velocities of the thermal capillary motion developed at the interface of contacting liquids depending on the specific power of internal heat sources and the longitudinal temperature gradient is given.

Published: May 2023

An algorithm of the stage-by-stage synthesis of combined energy sources based on a high-voltage electrochemical explosion (HVECHE) was developed. The algorithm provides the necessary space-time force and energy impact on processing objects to perform specified technological operations. At the first stage, the synthesis of an energy source based on a high-voltage electric discharge in condensed media was done by means of solving inverse synthesis problems and, as a result, determining the required total energy with its subsequent optimal separation into electrical and chemical components. Experimental studies of the dependence functions of the force impact on the processing object on the energy characteristics of the HVECHE were carried out. Based on those studies, the criteria for the optimal proportion between the electrical and chemical components of the required total energy were determined. An example of a specific use of the developed algorithm for the synthesis of a combined energy source based on the HVECHE was given, which confirms the possibility to use this algorithm for engineering calculations.

EFFICIENT USE OF STEAM THERMAL ENERGY

Published: May 2023

The results of theoretical studies of the use of selective steam of various parameters in consumer installations

are presented. The values of heat losses during the transportation of steam to the consumer are determined.

Heat losses during transportation are insignificant and do not exceed 0.05%. A TH-diagram of the thermodynamic

process of operation of selected steam during adiabatic expansion and condensation is presented. It is shown that

the main share of the thermal energy of steam is determined by the process of its condensation (up to 90% of the

initial heat content). To convert the thermal energy of the selected steam into mechanical energy during its adiabatic

expansion in the drive turbines of the consumer, it is necessary to choose the steam of the highest pressure.

This will allow saving up to 50% of heat compared to low pressure steam. An exergy analysis of the system for

the use of selective steam prior to its condensation has been carried out. The degree of thermodynamic perfection

of steam use in this area is 45%.

The steam parameters for heat exchange units with condensation are determined by the temperature difference

in the final section of the heat exchange path; otherwise, the initial steam parameters are practically

indifferent to them. The main requirement for such installations is the presence of a steam trap in the condensate

removal path and a reliable system for diagnosing its technical condition.
