Authors: Goloviznin S. M. , Petrov I. M. , Ivantsov A. B.
Published: November 2022

The paper continues the previous authors’ works in the field of wet wire drawing. The process of wet fine brass-plated steel wire drawing is considered. The subject of the paper is increase of the wire die wearability. The analysis of various wire drawing tools (hard alloy dies, synthetic diamond dies, natural diamond dies) was carried out for the relevance of its application for small diameter wire drawing. The authors studied the wire die wearability. The research methodology is presented, which include the procedure and conditions for measurements, industrial equipment and type of wire drawing machine. In the paper, the comparative analysis of the experimental data with the results of other authors for similar wire drawing tool was carried out. The authors calculated the main characteristics of the wire die wearability distribution (asymmetry, kurtosis, coefficient of variation). A statistical analysis of the array of experimental data for selection of more than 500 samples was performed. A high correlation of the drawing die wearability with the ratio of breaking stress to draw stress and a weak correlation with the drawing force and stress were revealed. The highest and most stable die life results are achieved when ratio of breaking stress to draw stress has values of 1.9 – 2.5. A formula was proposed for determining the optimal value of the ratio of breaking stress to draw stress, depending on the wire diameter. The formula allows one to determine the maximum die wearability values, depending on the wire drawing schedule. The work results can be used when designing new wet wire drawing schedules using synthetic diamond dies.
Determination of chlorine in dusty waste in ferronickel production: Analysis and estimation of uncertainty
Authors: Mitrofanova S. A. , Murav’eva I. V.
Published: November 2022

A key stage in ferronickel production is sulfate-chlorination roasting, after which and at subsequent stages (up to the final product) exhaust gases are formed in the system accompanied by dust and metal chloride vapors outlet in roasting furnace. Enrichment of wastes during their removal with condensed chlorides indicates a decrease in the efficiency of sulfate-chlorination roasting. Therefore, the control of mineral chlorine in filter sediments is important both from the standpoint of environmental monitoring and evaluation of the technological process efficiency. In order to determine mineral chlorine in dusty waste during the ferronickel production, a quantitative chemical analysis procedure based on the ionometric method was developed in the testing laboratory of the South Ural Nickel Plant. This paper proposes a procedure for estimating the results uncertainty in determining chlorine in the sample. It consists of the following steps: compiling a mathematical model to determine the chloride-ion mass fraction, estimating the input quantities in the mathematical model and their uncertainties, estimating the output quantities in the mathematical model and their uncertainties, budgeting for uncertainty, determining the expanded uncertainty and presenting the results. The paper considers the results of calculating the total expanded uncertainty in determining the chloride-ion mass fraction – U(XCl – ) = ±9.4 % (kp = 2, P = 95 %) – for the samples with chlorine mass fraction from 0.4 to 0.8 %. Application of the proposed methodology in calculating uncertainty ensures reliable results in determining chlorine in dusty wastes of ferronickel production, which has a positive effect on the technological process and environmental monitoring efficiency.

Authors: Kolomeichenko A. V. , Logachev V. N. , Deev V. B. , Dudareva N. Yu.
Published: November 2022

The method of electric arc metallization has both undeniable advantages and some disadvantages. For example, there is a burnout of alloying elements and a high content of oxides in the applied coating. Aerosol fluxing during metallization can solve this problem and neutralize the negative oxidative effect of interaction of the applied metal with air oxygen. This article discusses an effective method to improve physical and mechanical properties of an electrometallization coating using aerosol fluxing. The essence of this method is introduction of an aerosol together with compressed air into a torch of molten metal. This aerosol consists of an aqueous solution of the chemical inorganic materials. Such the aqueous solution is poured into a hydrodispergator, which is connected to the air channel of the metallizer. Aerosol fluxing makes it possible to deoxidize and ligate metal during electric arc metallization. As a result, the physical and mechanical properties of the metal increase. The paper considers the results of topographic studies of electrometallization coatings. Formed coatings have a structure with grain sizes from 200 to 2500 nm and also have pronounced and subtle grain boundaries. Aerosol fluxing with electric arc metallization forms a coating with finer-grained structure, which increases their strength. It is established that formed coatings have a finer-grained structure and increased strength when using aerosol fluxing during electric arc metallization. Metallographic studies showed that the thickness of the electrometallization coating varies from 2490 µm to 2586 µm. The use of aerosol fluxing during electric arc metallization does not significantly affect the coating thickness. The microhardness of electrometallization coatings was studied. This study showed that the use of aerosol flux consisting of Na2CO3 , Na3AlF6 , Na2B4O7 during metallization increases microhardness of electrometallization coatings by 1.6 – 1.9 times.

Published: November 2022

The objective of the research was to identify transitional diffusion layers in the steel wire – brass coating system. Brass wire is used in the production of steel cord. Such wire made from steel 80 by dry drawing, two-stage deposition of brass coating (Cu + Zn) and subsequent diffusion annealing was used for this research. The chemical composition was studied using a TESCAN Vega3 SBH scanning electron microscope with an Oxford Instruments attachment for X-ray microanalysis (MRSA). To obtain maps of the elements distribution, the overlay of the received frames was used. The authors studied chemical composition of the brass coating of steel wire for steel cord by spectra; the copper concentration gradient was determined; iron content in the coating and copper content in the steel core were revealed. The presence of a transitional diffusion layer from a brass coating to a steel core on a wire for wet drawing with a diameter of 1.67 mm and 1.85 mm was determined in two parts with different thicknesses of a brass coating in opposite sections (maximum and minimum). A map of the elemental distribution of Fe, Cu and Zn is shown, as well as a general map of overlay of Fe, Cu and Zn content; graphs of the elements’ content for two studied cross-sections are presented. It was established that the transition diffusion layer has gradient transition in concentrations of Fe, Cu and Zn, which characterizes good connection of the brass coating with steel. Diffusion layer of a brass coating of a steel wire with a diameter of 0.30 mm, produced by wet drawing of a steel wire with a diameter of 1.67 mm, was studied. An image of the coating was obtained by overlaying frames. Thickness of the coating together with the diffusion layer was determined, the average value of which is 1.4 µm with an apparent coating thickness of 0.5 µm.

Published: November 2022

The authors investigated the intensity of heating of a moving strip of thermally thin metal on a finite length section by a system of attacking neutral gas jets. The article is devoted to solving the problem of creating a system for heating a strip of moving metal by attacking jets of neutral gas by estimating the intensity of heating a metal strip using mathematical modeling methods. The main options for heat treatment of sheet metal are named. The article describes the differential heat conduction problem and its subsequent simplification, considering the assumptions made to obtain an effective calculation algorithm; the empirical relations selected for calculating local and average values of heat transfer coefficients; and the basic parameters for variant calculations. For comparative modeling, a 20m-long section was considered, where a strip entering with a temperature of 500 °С is heated by neutral gas with temperature of 800 °С. The results of calculating the dependence of average cross-sectional temperature of the strip on its movement speed (in the range from 0.1 m/s to 2 m/s) at two values of the gas flow velocity (20 m/s and 40 m/s) are presented, on the basis of which the authors concluded that acceptable heating intensity is achieved only at low speeds of the strip, and the gas flow rate (in the considered range) is not a reserve for a significant increase in this intensity.

Authors: Araujo Clemerson Luiz Pereira de , Carvalho Joelson Gonçalves de
Published: November 2022

This article analyzes the implementation of the policy to decentralize public environmental management, focusing on the municipalization of environmental licensing. The mechanisms adopted by the municipality of Araraquara, SP, for its environmental licensing were methodologically compared to the mechanisms used in the municipality of São Carlos, SP, by the state of São Paulo, through the CETESB, which is the state environmental control agency. A bibliographic survey and document analysis of the public agencies were conducted. The research elucidated that municipalized environmental licensing did not decrease the time required to approve licenses and that no investments were made to update the analysis processes, unlike the state, which went through a process to virtualize its license requests. However, the municipality of Araraquara conducts a more thorough analysis of licensed businesses to mitigate environmental impacts. This municipality also has greater contact between municipal public officials and the community, which demonstrates benefits in decentralization.
Climate Change Analysis Based on Satellite Multispectral Image Processing in Feature Selection Using Reinforcement Learning
Authors: Firdaus Muhammad Yus , Kamil Mustofa
Published: November 2022

Currently private and government agencies use remote sensing images (RSI) for various applications from military applications to agriculture growth. The images can be multispectral, panchromatic, ultra-spectral, or hyperspectral of terra bytes. RSI classification is considered one important application for remote sensing. Climate change detection especially affects numerous aspects of day-to-day lives, for instance, forestry management, weather forecasting, transportation, agriculture, road condition monitoring, and the detection of the natural atmosphere. Conversely, certain research works had a focus on classification of actual weather phenomenon images, generally depending on visual observations from humans. The conventional artificial visual difference between weather phenomena will take more time and error-prone. This paper develops a new reinforcement learning based climate change analysis on satellite multispectral image processing (RLCCA-SMSIP) technique. In order to properly determine climate change, the RLCCA-SMSIP technique employs residual network (ResNet-101) model for feature extraction. Next, deep reinforcement learning (DRL) approach is utilized for climate classification. Finally, parameter selection of the RLCCA-SMSIP technique involves sine cosine algorithm (SCA) for DRL model. For assuring the enhanced outcomes of the presented RLCCA-SMSIP model, comprehensive comparison results are assessed. The obtained values denote the supremacy of the RLCCA-SMSIP model on climate classification.

Published: November 2022

Lead (Pb) is a potential pollutant that readily accumulates in soils. IAA and NAA belongs to plant hormone auxin that promote plants growth. This work aim at examining possible ameliorative effects of Indole acetic acid (IAA) and Naphthalene acetic acid (NAA) on some biochemical parameters of soybean exposed to Pb toxicity. Seeds of soybean (TGX 1835-10E) genotype were sown in 5kg bags of soil containing 1000mg/L of Lead nitrate (PbNO3). 40mg/L, 80 mg/L and 120mg/L each of IAA and NAA were prepared and applied by foliar method after 5 weeks of planting. Photosynthetic pigments, mineral elements and antioxidant enzymes were determined on the root, stem and leaf after 7 weeks of planting. Data were analysed using anova at 5% level of significance. The results showed that the level of chlorophyll a, b and carotenoid, mineral elements and antioxidant enzymes significantly increased in the root, stem and leaf of soybean treated with different concentration of Indole acetic acid (IAA) and Naphthalene acetic acid (NAA) as compared with the control (C+ve). All bioregulators (IAA and NAA) concentrations significantly decreased in the level of Pb2+ (except 40mg/L IAA in the root and leaf while all concentration have significant effects in the stem) and also all concentration of (IAA and NAA) significantly increased in the level of biochemical parameters to different extent as compared to control(C+ve). These results show that Indole acetic acid (IAA) and Naphthalene acetic acid (NAA) could ameliorate the Pb toxicity and therefore will be of relevance to agricultural producers.

Backgraund: The presence or absence of fungi on the seed surface is an important aspect that determines the quality of seeds. Since the data on the presence of Fusarium spp. and other seed-borne pathogens on vegetable pea in Serbia are scarce, the aim of this study was to isolate seed-borne pathogens and identify the disease-causing Fusarium spp. from the infected pea seed. Methods: Colony morphology and microscopic characters of isolated Fusarium species were recorded from the cultures grown on PDA and CLA, respectively. In order to confirm the morphological identification at the species level, a single-spore culture of the representative isolates was subjected to genomic DNA extraction and gene amplification using the translational elongation factor 1α (TEF-1α) region. The PCR products were sequenced and the sequences were compared against the GenBank nucleotide database by using the BLAST alignment. Result: Based on morphological and microscopic characteristics, as well as molecular identification by sequencing the TEF gene, the presence of Fusarium equiseti and F. proliferatum was confirmed on the representative isolates Ps18, Ps19 and Ps1, Ps36 obtained from vegetable pea seeds, respectively. According to our knowledge and research, this is the first report of F. equiseti and F. proliferatum on vegetable pea seeds in Serbia.

Aim: To investigate feasibility and acceptability of positive psychotherapy for acute psychiatric ward patients and staff, when delivered by non-psychology clinical staff, and co-produced with staff with lived experience. Method: Group or individual strengths-based positive
psychotherapy was led by an activity coordinator and co-facilitated by a peer support worker with lived experience of mental health problems. It was delivered for acute ward patients and staff. Feasibility was measured by completion of session components and percentage of participants able
to identify a strength, plan a strength-based activity, and activity completion. Acceptability was measured by comparing pre- and post-session mood, and with helpfulness ratings and narrative feedback. Results: Participants (n = 22) included 12 patients and 10 staff members. Participants
were mainly female and of white or mixed ethnicity. Most patients had a psychotic disorder. Staff were nurses and healthcare assistants. The most identified strengths were self-regulation, social intelligence and perseverance. Typical activities included activity-scheduling, sleep hygiene,
walking, gardening and cooking. High completion rates for components and activities indicated feasibility. Lack of adverse effect on mood, high helpfulness ratings, and positive feedback indicated acceptability. Conclusion: This evaluation indicates that non-psychology staff can deliver
psychological interventions, that interventions can be co-produced with staff with lived experience, and that patient and staff participants can collaborate on these interventions. This shows how psychological interventions on acute wards can be inclusive, positively impact on ward culture,
and be more widely delivered to support patients and staff.

Walking is said to increase endurance, burn calories and improve cardiovascular health. To monitor the steps when walking, we need a tool that is a gyroscope sensor MPU6050. Making this tool uses a gyroscope sensor for monitoring footsteps because Gyroscope is used to measure or determine the orientation of an object based on the provisions of angular momentum. This tool has been tested by foot with a number of different steps. The device test carried out by one person testers.Data obtained from these tests resulting from the detection lower limit value and upper limit value of X axis angle data is used in data processing is the value of the X-axis is converted into a sine wave form chart. To detect footsteps, each wave has the upper value limit is 20o and the bottom value is -20o. Once the step is detected, these measures will be multiplied by the width of the foot when walking, then obtained distance

On the development of the database currently has become a very important thing, each will plan something, consider any thing we will need and use existing data in a database, The development of the database currently has become a very important thing, when we want to plan something and consider everything,  we will need and use existing data in a database, PostgreSQL is one Object Relational Database Management Systems (DBMS) open source with a lot of features that are not less sophisticated to commercial databases. On daily use, it sometimes occurs  a case that requires a dynamic column, therefore we should make the new columns to meet those needs. However, if each row of the table column requires  different  column and potentially need another ones, then it is going to be useless. On the research of utilizing the technology of JavaScript Object Notation (JSON),Json_encode PHP programming language can simplify the use of the column so that  a new column is  no longer needed when we want to create a new column on the table, we only need a new column that stores an array that has been converted into a JSON string forms the result of json_encode that represents the column name and the content of the columns of a table.
Massive Spatial Well Clustering Based on Conventional Well Log Feature Extraction for Fast Formation Heterogeneity Characterization

Published: November 2022

Recent enhancements in computational capacity provide an opportunity for harnessing the enormous amount of reservoir data already acquired and extracting useful information for hydrocarbon exploration, development, and production. This article reports a three-step clustering technique to determine well groups based on subsurface geological heterogeneity using feature extraction, hierarchical ensemble clustering, and spatial mapping. The first step of the presented methodology is to group the wells into different clusters based on the formation rock composition and property features extracted from well logs using the expectation maximization algorithm. The one-dimensional (1D) stacking pattern of each well log curve is expressed through a two-dimensional (2D) transformation scheme. Thus, the clustering can capture the vertical stacking patterns of well logs, which is essential for reservoir heterogeneity characterization. This base clustering process generated a feature matrix which is further grouped through the hierarchical ensemble clustering in a latent space of well logs in the second step. Through the ensemble clustering, different clustering proposals obtained from the base clustering are integrated corroboratively to reflect a comprehensive feature of all studied logs. In the third step, the spatial clustering is performed based on the ensemble results, considering the spatial distances between well locations in the target area. The results of the 2D spatial map may provide insights into the sedimentary depositional environment in terms of the lateral geological heterogeneity features. Therefore, the proposed clustering technique can present a fast geological modeling method to integrate geological heterogeneity features presented in multiple well logs, which is not yet fully utilized in traditional geomodeling approaches. The results can also support further reservoir studies, such as petrophysical modeling, reservoir modeling, and fluid flow simulation studies.
