Issues of technology and conditions of smelting of low-silicon cast iron in blast furnaces
Authors: Kobelev V. A. , Onorin O. P. , Spirin N. A.
Published: November 2023

The issues of technology are considered and the conditions for smelting cast iron with a low silicon content (0.2‒0.3%) in blast furnaces are discussed. The relation between the regime parameters of the blast furnace and the silicon content in the cast iron is analyzed using actual data. One of the conditions for obtaining the cast iron with a low silicon content is a reduced heating of smelting products, i.e. the implementation of the technology of cold blast furnace smelting. It is shown that low-sulfur low-silicon cast iron is possible with a decrease in the fluctuation of the chemical composition of iron ore raw materials and an improvement in the quality of coke, in the production of raw materials in which silica is bound into hard-to-recover silicates, while controlling the chemical composition of all raw materials in the stream. To reduce the concentration of silicon in cast iron, it is necessary to increase the basicity of the slag (CaO/SiO2) and increase the concentration of MgO in the slag with a ratio in the slag Al2O3/MgO = 0.85‒1.10. In this case, calcium silicates CaO•SiO2 (or even bicalcium silicate 2CaO•SiO2) are formed in the slag system), from which silicon reduction is more “hard” than from free silica. The transition of silicon from the gas phase to cast iron depends on the reaction surface area of the metal-gas contact. Therefore, by reducing the thickness of the cohesion zone and the residence time of the melts in this zone, it is possible to reduce the saturation of cast iron with silicon. It is shown that in the production of low-silicon cast iron it is necessary to work with the opened center ‒ to carry out the axial gas flow. The contact time of cast iron and gas in the cohesion zone is also determined by the properties of coke ‒ primarily by its hot strength. With low hot strength, coke significantly impairs the properties of the coke oven nozzle and increases the metal filtration time in the lower part of the furnace ‒ in the coke oven nozzle zone, thereby contributing to the saturation of cast iron with silicon. The silicon reduction process is accompanied by an increase in the volume of the gas phase. Therefore, increasing the pressure in the blast furnace makes it difficult to recover the silicon. In the production of low-silicon cast iron, smelting must be carried out at high blowing pressure. As the blast pressure increases, it is necessary to increase the excess pressure of the top gas, establishing the necessary difference in gas pressure along the height of the charge layer. Increasing the specific productivity of the blast furnace is an effective factor in reducing the concentration of silicon in cast iron. This is associated with an increase in the flow rate of liquid melting products, a reduction in their residence time in the cohesion zone and, consequently, to a decrease in the silicon content in cast iron.
Analysis of phase equilibria in liquid chromium-manganese steels in the presence of calcium. Report 1. Phase diagrams of oxide systems.
Authors: Mikhailov G. G. , Makrovets L. A.
Published: November 2023

The metallurgical industry produces a wide range of chromium-manganese steels, deoxidized and modified with calcium. To determine the non-metallic inclusions (NI) that can form in the Fe–Ca–Cr–Mn–C–O system, it is necessary to study the double and triple phase diagrams included in the FeO–CaO–MnO–Cr2O3 system. Divalent chromium oxide, which is also included in the oxide melt in the Fe–Ca–Cr–Mn–C–O system, practically does not occur in the literature as a component of double or triple state diagrams; therefore, the activity of chromium(II) oxide was equated to its ion fraction and state diagrams with it were not considered in this work. The state diagrams of oxide systems FeO–CaO, FeO–MnO, FeO–Cr2O3, CaO–MnO, MnO–Cr2O3, and FeO–MnO–Cr2O3 were previously studied by the authors. In this work, the state diagrams of the CaO–Cr2O3, FeO–CaO–Cr2O3, FeO–CaO–MnO, and CaO–MnO–Cr2O3 systems are calculated and plotted. The mixing energies are selected to determine activities in solid (theory of regular ionic solutions) and liquid (theory of subregular ionic solutions) oxide solutions to calculate the coordinates of the liquidus and solidus lines of these state diagrams. The enthalpy (103.4 KJ/mol) and entropy (21.958 J/(mol•K)) of melt-ing of calcium chromite CaCr2O4 are specified. The invariant points of the state diagrams of the FeO–CaO–Cr2O3 and CaO–MnO–Cr2O3 systems have been determined. The study of double and triple phase diagrams belonging to the FeO–CaO–MnO–Cr2O3 system will make it possible to determine all possible NIs that can form in chromium-manganese steels in the presence of calcium under equilibrium conditions.
Manufacturing, curing and mechanical testing of BREX from electric arc furnace dust
Authors: Grigor’ev E. V. , Kapelyushi Yu. E.
Published: November 2023

At present the acute issue is utilization and recycling of metallurgical production wastes; one of which is electric arc steelmaking dust (EAF). In Russia there are up to 30 million tons of dust in the dumps of metallurgical plants and additionally up to 780 thousand tons are added to this amount annually. Considering the amount, the main value is zinc, which content reaches 25 wt%, as well as iron, which content varies from 20 to 50 wt%. The paper presents the results of studies on briquetting of the EAF dust using the technology of stiff extrusion and obtaining brackets. The chemical composition of the initial EAF dust was studied by X-ray spectral analysis using JEOL JSM-7001F electron microscope. The amount of reducing agent was selected based on results of thermodynamic modeling using the TERRA software package. The BREX were produced in a laboratory extruder assembled from an electric motor, a reduction gear, a screw, and a die. Two types of dies were used in the briquetting study. For each type the optimum moisture and binder were selected. The influence of the binder and moisture on the quality of the finished briquettes was evaluated. The BREX drying was studied in order to find out the optimum curing time in the air. In addition, drying at 110 °C was carried out for a comparative assessment of the strength of briquettes depending on the method of drying. The drop tests of the finished briquettes were carried out according to GOST 25471‒82 “Iron ores, sinter and pellets; method for determining dumping strength”. The test results showed the possibility of transportation of the EAF dust briquettes
Influence of the technology of thermal diffusion chroming on the depth of the diffusion layer
Authors: Shaburova N. А. , Pashkeev I. Yu.
Published: November 2023

Previously, the author’s works were shown that the introduction of powders of electron emitters or oxygen anions into the composition of the technological filling creates an electric field between the particles of the filling and the part to be saturated. The cumulative effect of this field and the diffusion flow leads to the intensification of diffusion processes and an increase in the diffusion depth of the main saturating element, chromium. This paper presents new results on improving the technology of thermal diffusion chromium plating of structural steels through the use of an internal emission field. In the experiments, the saturation of 35X2H3 steel samples was carried out in sealed containers at a temperature 1000°C for 24 hours. The elemental composition of the diffusion layer was monitored on transverse sections in the direction from the saturated surface to the base metal of the sample using a JEOL JSM-6460LV universal scanning electron microscope. The microhardness of the coatings was measured on an FM-800 microhardness tester. It is shown that partial or complete replacement of aluminum oxide in the technological filling with powders of natural and artificial oxide materials (serpentine and scheelite) has a positive effect not only on the knock-out of parts from containers, but also significantly increases the depth of the chromium diffusion layer. Moreover, the most effective is the use of scheelite powder in the saturating mixture. The use of additional equipment for thermal diffusion chromium plating in the form of cumulative gratings, both for chromium plating in mixtures of traditional composition and in mixtures with minerals, provides an increase in the depth of chromium diffusion by at least 2 times and an increase in the hardness of coatings from 10 to 70 HV. It also enriches the surface layers of the saturated part with the lattice metal element.

The price of medicines is an important factor in ensuring accessibility for the population in the healthcare. Ukraine actively implements pricing policies in the healthcare in accordance with the recommendations of the World Health Organization (WHO). WHO recommendations aim to achieve two important objectives. First, they seek to ensure the availability of effective medicines for the population so that every patient has the opportunity to receive necessary treatment. Second, it is to create conditions for pharmaceutical companies to have incentives to continue their innovative activities in the field of medicine. The purpose of the research is to analyze and evaluate pricing policies that ensure the accessibility of medicines for the Ukrainian population through state budget funding and their compliance with WHO recommendations. It has been established that in Ukraine, there are several directions aimed at ensuring the population's accessibility to medicines through state budget funding: the purchase of medicines within the National Essential Medicine List, the «Affordable Medicines» program, centralized procurement of medicines and the purchase of innovative medicines through Managed Entry Agreements. Pricing for medicines under various programs is carried out using different approaches. An analysis of the legislative environment regulating medicine pricing in Ukraine in accordance with WHO-recommended pricing policies has revealed that several pricing policies are functioning at a satisfactory level. These include external and internal reference pricing, mark-up regulation, cost-based pricing, as well as tax exemptions or reductions for medicines. However, there are policies that require further development and improvement. These include promoting price transparency, conducting tenders and negotiations, consolidating procurement, promoting the use of generics and biosimilars with guaranteed quality, as well as introducing cost-plus pricing to determine medicine prices. Thus, standardization of the lists of medicines and pricing approaches is one of the most important tasks on the path to European integration. Monitoring market prices with control over their compliance is a necessary step to improve the population's access to effective medicines.

This paper reviews the key risk factors and clinical manifestations of blue sclerae, which include a large group of diseases of various origins. Generally, this syndrome is genetically determined and is a constant phenotypic sign of osteogenesis imperfecta. In addition to the classic triad of blue sclera, brittle bones, and hearing loss, many authors refer glaucoma to as an ocular manifestation of brittle bone disease in addition to thin cornea and low corneoscleral rigidity. The combination of osteogenesis imperfecta type 1 and primary open-angle glaucoma is a novel phenotypic association. The most effective way of controlling intraocular pressure (IOP) in this condition is surgical intervention. Case report of a combination of glaucoma and syndromic connective tissue disease that appeared 15 years after the first visit to an ophthalmologist for recurrent ocular hypertension is presented. Selective laser trabeculoplasty and a fixed-dose combination of 0.3% bimatoprost and 0.5% timolol provided normal IOP levels. Ultrathin corneas and systemic hypotension do not rule out the need for further surgery. KEYWORDS: blue sclera, glaucoma, osteogenesis imperfecta, corneal thickness.

Surface area values for the human stomach including changes in length and diameter or width with meal volume
Authors: Hurr Thomas
Published: November 2023

To quantify the amount of solid, liquid or gas that can be adsorbed on to a surface, the surface area must be known. Equations were developed to calculate the macroscopic surface area of the adult human stomach in vivo, at any given meal volume. For a meal volume of V≈0-2000 cm3, the surface area SA≈113-1030 cm2 and by using a cylinder-shaped stomach model, the diameter D≈2.4-10.3 cm, length L≈27-32 cm and width W≈ 7.5-32 cm. The cylinder model found for a given volume, the standard deviation in average surface area values may result from fluctuations in both length, diameter and width, indicating the stomach, by changing shape, changes surface area.

Authors: Zhang Minghui , Xu Juncai , Zhang Xiaoping
Published: November 2023

In the context of global warming, changes in precipitation patterns and the increase in extreme weather events have had a serious impact on regional development. In order to grasp the temporal and spatial distribution characteristics and trend changes of precipitation in Xinjiang, this paper uses TRMM3B43v7 data to interpolate with radial basis function method, inverse distance weighting method, ordinary kriging method and ANUSPLIN interpolation method, and uses evaluation indicators to determine the best interpolation method. The results show that the applicability of TRMM data in Xinjiang is good, but it is overestimated, and the average monthly scale is 1.30mm higher. Precipitation in Xinjiang is mainly concentrated in the north of the Tianshan Mountains, and less in the south. From 1998 to 2019, the precipitation trend in Xinjiang showed an increasing trend, with more than 63.64% of the total area of Xinjiang showing an increasing trend, and the western region showed a significant increase, while the eastern region showed a slight decreasing trend.

Some features of the bioecology of the apple moth Cydia pomonella L. in the conditions of the Moscow region
Authors: Zeynalov A. S. , Orel D. S.
Published: November 2023

Relevance. Cydia pomonella L. (Lepidoptera: Tortricidae) is a dominant pest that annually causes significant damage to apple crops. Without a detailed study of the bioecological features of the development of the phytophage in specific study areas, which have undergone noticeable changes under the influence of global warming, it is impossible to build an effective protection system and ensure their environmental safety.

Methods. The object of research is C. pomonella. When studying the age gradation and timing of the presence of caterpillars in fallen fruits, conventional and original methods were used; the width of the caterpillar head capsule was measured under an MBS-10 stereoscopic microscope using eyepieces with microscopic rulers. The study of the influence of the photoperiod on the behavior of C. pomonella under short day conditions was carried out in the laboratory in special containers, under natural light and at room temperature (about 21 °C).

Results. Studies have shown that not all C. pomonella caterpillars leave fallen fruits within a maximum of one day. After three days of selection and analysis of fallen damaged fruits, caterpillars were found in 34.6–35.5% of them: 18.3–28.3% – age V, 18.3–30.2% – age IV, 28.3–47.9% – III age, 13.2–14.1% – II age, 1.4% – I age. In the laboratory, under short day conditions, according to the years of research, during October – November, 20–21.4% of butterflies flew out of the number of caterpillars of the last age that did not have time to form cocoons in the field.

Published: November 2023

The purpose of the research is to monitor rare species of narrow–leaved peony (Raeopia tenuifolia L.) and Biberstein peony (R. biebersteiniana (Rupr.) in places of natural growth – at the foot of Mount Strizhament and on the western slope of the Nedremanny ridge (from the side of the farm of the Novokavkaz Stavropol Territory) (in 2008–2022) – and culture. Monitoring showed that the composition and structure of the steppe cenosis were changed by grazing farm animals, digging and collecting bouquets. The initial stage of pasture degression occurs. The population of the narrow – leaved peony varies from 10 to 25 pcs/m². At the same time, the total number of the species is decreasing. The age spectrum is changing towards a decrease in young plants, in particular juvenile plants, more plants are in the generative phase. Seedlings and young plants decreased by half during the observations – from 38 to 19%, at that time no prussic individuals were found. The population is still self-regenerating due to annual seed-bearing. The occurrence of Biberstein peony plants is from 3 to 19 pcs/m2. The population is also self–healing, the projective coverage is up to 80%. But there is also a tendency to decrease the proportion of young plants due to uncontrolled grazing (the foot of Mount Strizhament) and annual haymaking (the western slope of the Nedremanny ridge from the side of the Novokavkazsky farm). The narrow-leaved peony and the Biberstein peony are resistant to diseases and pests in the conditions of culture, reproduce vegetatively and by seeds, retain habit, and are very promising for gardening.

Published: November 2023

The influence of the composition of the diet on the productive indicators of cows, in particular on the chemical composition of milk, is analyzed. A reduction in the supply of succulent feed to 46.6% of the total energy nutrition and an increase in the proportion of concentrates (up to 53.4% of the exchange energy) for dairy cows were unacceptable. During the study, the level of milk productivity of black-andwhite cows increased very slightly – by 0.7 kg head /day. It is possible that in the first days of the change of the cow's diet, the total gross milk yield increases, but this period does not last long, and soon cows with acidosis and other metabolic disorders appear on the farm. The increase in the level of concentrated feed in the farm negatively affected the physico-chemical composition of milk, which became unsorted. A negative consequence of the change in the diet of cows was a deterioration in the quality of milk. Thus, the ratio of «fat – protein» has changed in the opposite direction, the urea content has increased (to 48.58–52.97 mg / 100 ml), the titrated acidity of milk has increased (to 19.49–21.04 °T) and the content of somatic cells in milk (to the level of 354.41–450.54 thousand / cm3) in cows of all lactations.

Технологія портфоліо дозволяє вчителеві продемонструвати свій рівень професійної компетентності, узагальнити й презентувати результати педагогічної діяльності, професійні досягнення, набуті знання й навички, методичні вміння, володіння інноваційними педагогічними технологіями, об’єктивно оцінити власні можливості, а також спланувати дії для досягнення кращих результатів. У нормативних освітніх документах затверджено вимогу щодо створення вчителем електронного портфоліо. Перевагою електронного портфоліо є те, що його можна публікувати на сайті ЗЗСО, власному блозі чи сайті, розміщувати в педагогічних спільнотах, у соціальних мережах, демонструючи в такий спосіб рівень професіоналізму педагога та його досягнення. З’ясовано, що у процесі створення педагогічного е-портфоліо здобувачі вищої освіти набувають умінь педагогічної рефлексії, необхідної для професійного розвитку і кар’єрного зростання, вчаться об’єктивно оцінювати та презентувати власні педагогічні досягнення, оволодівають навичками створення особистісно-професійного іміджу, що сприяє формуванню професійної компетентності майбутнього фахівця. Авторами статті змодельовано й описано структуру електронного портфоліо майбутнього вчителя початкових класів. Його компонентами визначено: особисту інформація; навчальну діяльність; науково-дослідну діяльність; міжнародну діяльність, культурно-освітню діяльність; самооцінку професійної компетентності та рівня розвитку професійно-особистісних якостей. Визначено цифрові інструменти для створення е-портоліо: ресурси для створення презентацій (PowerPoint, Canva, Prezi); сервіси Google Sites, Wakelet; платформи для створення власних сайтів Wix, Onepage.

У статті обґрунтовано поняття гейміфікації як одного з методів для проведення занять інформатики в початковій школі. Описано важливість активізації пізнавальної діяльності учнів та формування в них цифрової грамотності, залежно від доцільного використання педагогом методів та інструментів для досягнення найкращого результату в навчанні. Аналіз літературних джерел дозволив трактувати поняття гейміфікації як концепцію, що базується на використанні ігрових елементів в процесі навчання. Сформовано основні принципи важливості використання ігрових методів в процесі навчання, а саме зацікавленість та мотивація, розвиток навичок співпраці та комунікації, формування аналітичного та критичного мислення. Здійснено аналіз основних переваг та недоліків, спричинених використанням ігрових методів в педагогічній діяльності. До переваг віднесено підвищення мотивації учнів, розвиток ключових навичок, індивідуалізація навчання. Серед недоліків виділено: негативний вплив на здоров’я дитини при тривалому використанні комп’ютерних пристроїв, складність використання та впровадження ігрової діяльності в навчальний процес. Досліджено програмні складові та веб-сервіси як інструменти в процесі використання гейміфікації на уроках. Описано характеристики та вимоги до них, як інструментів для ігрової діяльності на уроках в початковій школі. Наведено переваги та недоліки програмних та вед-сервісів, можливості їх використання. Доведено твердження, що гейміфікація на уроках інформатики для молодших школярів являється дієвим та ефективним методом навчання. Вона підвищує мотивацію учнів, сприяє розвитку ключових навичок та індивідуалізації навчання. Отже, використання гейміфікації в освіті слід розглядати як перспективний шлях до покращення якості навчання та підготовки молодого покоління до викликів сучасного світу.

Sistem Kredit Poin atau SKP merupakan sebuah wadah yang disediakan oleh fakultas untuk meningkatkan kompetensi mahasiswa. Kompetensi tersebut dapat berupa prestasi akademik maupun non akademik, selain itu keikutsertaan mahasiswa dalam kegiatan ormawa (organisasi mahasiswa) juga dapat dihitung dengan poin-poin tertentu dalam SKP ini. Banyaknya mahasiswa di lingkungan Fakultas Teknik dan Kejuruan membuat penginputan SKP dengan cara manual dinilai kurang efektif dan efisien. Data poin SKP yang tercatat dalam buku secara manual menyebabkan sering terjadinya kekeliruan antara pencatat dengan mahasiswa. Selain itu, pengadaan buku SKP juga membuat fakultas harus mengeluarkan anggaran setiap tahunnya untuk mencetak buku, dan saat pengisian SKP mahasiswa juga diwajibkan untuk datang ke sekretariat BEM FTK yg dirasa kurang efisien. Berdasarkan permasalahan tersebut, solusi yang ditawarkan adalah pembuatan Sistem Informasi Layanan SKP berbasis Website di BEM FTK Undiksha. Dengan Sistem Informasi Layanan ini, bagian pendataan dan juga administrasi akan lebih dipermudah sehingga dapat meminimalisir adanya kekeliruan penginputan poin
