Authors: Bolognesi C. M. , Manfredi V.
Published: February 2024

Abstract. The research question underlying this short essay refers to the possibility of realizing through a well-established workflow a high level of immersivity in the VR representation of Cultural Heritage to be used as a working tool by architects and renovators as well as heritage scholars. At present active or passive 3D scanning techniques are a known reality where the choice of data acquisition system depends both on the final purpose and characteristics of the object to be surveyed. With the maturity achieved in point cloud acquisition, post processing phases and the development of BIM-based systems, the model has given the possibility to become a repository of information related to the existing, to be used for maintenance or renovation processes. If the model can represent the existing with a certain level of detail, it can be assumed that a differentiated Level of Immersivity can be organized depending on the specific needs it intends to fulfil. In the context of renovation or preservation of Cultural Heritage, the potential offered by VR becomes more interesting when it can provide a realistic portrait not only of the geometry, but also of the materiality and state of preservation of the buildings. This research opens new possibilities to develop tools to aid designers and renovators in degradation analysis, intervention projects, and scheduled maintenance. The research question starts analyzing the possibility of creating photorealistic immersive environments that are easy to access, organized based on surveys of existing heritage buildings using specific datasets.
“Al infierno, para siempre jamás”: la política afectiva del miedo en la primera parte de Sermones de los misterios de nuestra Santa Fe Católica, de Fernando de Avendaño
Authors: Saito Gutiérrez Gabriela
Published: February 2024

Desde el enfoque de la historia cultural para la lectura detallada de la prosa colonial, se plantea que la (re)presentación de una pedagogía paternalista y castigadora en la primera parte de los Sermones de los misterios de nuestra Santa Fe Católica, de Fernando de Avendaño, implica la constitución e implementación tanto de una pragmática como de una retórica del miedo a Dios, al infierno y a la naturaleza humana del pecado para crear una metanoia cristiana, en última instancia, colonial. Considerando al miedo como una política afectiva y a la metanoia como la conversión cristiana e integral de las formas de vida tras la refutación de un sistema religioso-cultural no cristiano, se propone analizar cómo este corpus, bajo el discurso ideológico de la ortodoxia colonial, organiza una pedagogía del miedo como instrumento de construcción y de control del sujeto indígena.
La solterona: arquetipo del horror proyectivo en las narrativas de lo siniestro
Authors: Poblete Alday Patricia
Published: February 2024

Este artículo analiza el tratamiento narrativo de la figura de la solterona en algunas obras de ficción contemporánea escritas por mujeres en Hispanoamérica, que se inscriben en la línea de lo fantástico que hemos denominado como “siniestro”. A través de una breve revisión histórica del surgimiento y aplicación del término “solterona”, se busca mostrar cómo, pese a los avances en materia de reivindicación de género, este arquetipo mantiene prejuicios sociales y morales que querríamos asumir como obsoletos. Se revisan someramente obras de Patricia Esteban Erlés, Cecilia Eudave, Giovanna Rivero, Claudina Domingo, Mariana Enríquez, Mónica Ojeda y Bibiana Camacho para profundizar, luego, en el análisis de sendos relatos de Yeniva Fernández y Solange Rodríguez Pappe. Las conclusiones muestran cómo la solterona se yergue, en esta narrativa, como una figura del horror proyectivo, que revela nuestros miedos e inseguridades como sociedad antes que las (supuestas) carencias y defectos de quien nunca ha contraído nupcias.

Raising temperature of the blast-furnace air is one of the well-known ways to save coke in iron production. To heat the blast-furnace air, hot-blast stoves are used, which are usually heated by blast furnace gas. Since the composition and calorific value of blast furnace gas are insufficient to achieve a blast furnace gas combustion temperature that ensures sufficient heating of the nozzles of hot-blast stoves to heat the blast-furnace air at 1160-1230 °C, various methods are used to increase the blast furnace gas combustion temperature. This paper investigates the effectiveness of one of these methods – the use of a mixture of atmospheric air, flue gases, and process oxygen as an oxidant for combustion of blast furnace gas in a hot-blast stove. To prepare the mixture, the hot-blast stoves are equipped with additional equipment: a heat generator for combustion of blast furnace gas with atmospheric air, and a mixer, where high-temperature flue gases generated during fuel combustion in the heat generator are mixed with atmospheric air and process oxygen to form a gas mixture containing 21% of oxygen. The use of the gas mixture prepared in this way increases the combustion temperature of the fuel in the hot-blast stoves, provides an increase in the heating temperature of their nozzle and increases the temperature of the blast-furnace air. The results of the work include a comparison of the efficiency of this method with other known methods of increasing the combustion temperature of blast furnace gas in the hot-blast stoves: enrichment of blast furnace gas with natural gas, heating of air and blast-furnace gas before combustion, and enrichment of combustion air with process oxygen. The paper shows that the use of a mixture of atmospheric air, flue gases, and process oxygen has some advantages over other methods, namely, it does not lead to a significant reduction in the rate of flue gases generated during fuel combustion in the hot-blast stoves, does not decrease heat exchanger in the nozzles, and increases the full use of the enterprise's own energy resources (blast furnace gas and process oxygen) in the presence of their excess. The disadvantages of using the mixture include the possibility of forming an explosive mixture when mixing process oxygen with high-temperature fuel combustion products that may contain carbon monoxide. Therefore, the issues of safe implementation of mixing flue gases, process oxygen and atmospheric air require further research and detailed development of the mixer design.

The aim of the work is to increase the efficiency and stability of the desulphurization process by blocking the resulfurization of pig iron in the process of technological operations for the preparation of blast furnace pig iron for converter processing at Azovstal Iron and Steel Works. Technological control of each of the technological operations on the route "blast furnace - desulphurization - slag pumping - mixer department" was performed, with sampling of pig iron, slag and chemical composition control to establish the actual sulfur content transferred from slag to pig iron in the process of pig iron release from the blast furnace to the iron ladles. The research carried out at Azovstal Iron and Steel Works in the process of iron discharge from blast furnaces and pouring into ladles includes 20 discharges or 53 ladles. The results obtained during the process control confirmed the previously established regularities that technological operations with desulphurized pig iron before it is poured into converters are not accompanied by pig iron resulfurization. It was found that the sulfur content in the mixers after the controlled portions of desulphurized pig iron were poured out, with almost no deviations (within the error of the rapid analysis), corresponded to the calculated values determined taking into account the mass of pig iron in the mixer and the sulfur content in it before overflow. Recommendations for corrections to the initial sulfur content for blast furnaces have been developed, which will increase the stability of the results achieved during the desulfurization of cast iron in the cast iron desulfurization department when setting the required consumption of magnesium reagent. The obtained results of the studies have shown that in order to increase the efficiency of technological and technical solutions for sulfur control, it is advisable to rationalize ladle slag regimes, including by adjusting the composition of ladle slag and thoroughly cleaning cast iron from high-sulfur slag.

Today, the metallurgical industry, as the main producer of structural material, sets new, increased requirements for the operational qualities of steels, which determine the reliability and durability of parts and structures. The methods of improving the properties of steels are quite diverse, but an important place among them is alloying, including nitrogen. The nitrogen alloying allows to reduce the content of more valuable elements in alloys while maintaining the necessary strong structure and high corrosion characteristics of alloys, plasticity, etc. Nitrogen is a fairly widespread chemical element and has long been known as an alloying agent, but its limited solubility in iron alloys, especially with a high content of other components, prevents its widespread use. Different methods of gas activation are used to increase the solubility of nitrogen. The authors investigated the option of activation by creating an electric discharge on a physical stand. The area of the lance at the outlet for the supply of purging gas was subject to modeling, on the path of which a gas activation device was placed by creating an electric discharge between the electrodes. It was established that to ensure electrical activation of a nitrogen-containing gas jet, it is possible to create an electric arc or corona discharge, the type of which depends on the distance between the electrodes. In order to ensure the effective interaction of the gas flow with the electric discharge, it is necessary to ensure the gas pressure at the level of 0.8-1.2 atm, and to place the blowing device at a height above the electric discharge at the level of 20-40 gauges. Compliance with the specified parameters will ensure effective interaction of the gas jet with the electric discharge in the form of an electric arc or corona discharge.

The work is devoted to the consideration of the feasibility of developing in the converter shop of PJSC "Kametstal" (DMK) the technology of vacuum degassing of carbon and flake-sensitive steel grades using modern equipment for the appropriate purpose in order to reduce the content of gases and non-metallic inclusions in metal products. Vacuuming of liquid metal outside a steel-smelting unit has opened up fundamentally new opportunities for increasing the entire complex of physical and mechanical properties of steel for various purposes and the efficiency of metallurgical production. The manifestation of significant interest in this process in the twentieth century was caused by the fact that it opened up new, more advanced technological capabilities in the implementation of deep deoxidation, decarbonization, alloying and degassing, which provided a significant increase in the quality of the steel produced. An important feature of the vacuum degassing process is the possibility of carrying out, at a slight vacuum (0.5-5.0 mm Hg), a sufficiently deep deoxidation of the metal contained in it with carbon, during which dissolved gases are simultaneously removed. This makes it possible to abandon the use of manganese, silicon, and in some cases aluminum as deoxidizers and thus solve the most difficult problem of steelmaking - obtaining clean steel in terms of the content of non-metallic inclusions and gases. At domestic metallurgical and machine-building enterprises, with the help of chamber-type vacuum degassing installations (VD), the production of steel of various grades has been mastered. One circulation-type degassing unit (RH) is also in operation in Sumy. At modern foreign metallurgical and machine-building enterprises, effective use of vacuum degassing installations of RH, DH (batch type) and VD types has been found. Moreover, in the last decade, the use of the RH method has expanded significantly, especially in the metallurgical industry of European countries, the USA and Japan. The current work is devoted to the consideration of an important issue for DMK - the determination of methods for vacuum degassing of steel that are acceptable for the conditions of the enterprise, taking into account the characteristics of the grade of steel produced now and in the near future.

It is known that steel production involves the use of various solid additive materials, which are introduced into the liquid metal bath at the stages of converting and outfurnace processing. The vast majority of such materials are supplied in lump form and in significant quantities. The volume of the additive can vary from 0.05 to several tens of kilograms per ton of molten steel, depending on the technological production conditions and other requirements. Until now, various studies and calculations on the efficiency of using additive materials in steel production were based on considering the behavior of their separate piece in a liquid metal bath. At the same time, the theoretical description of the hydrodynamic state of the metal bath did not take into account the influence of the amount of added additive. At the same time, as it seems to the authors of the article, it is precisely this factor that can influence the accuracy of the calculated results and, most importantly, increase the error in further assessment of the effectiveness of using high-value and mainly imported materials. The article, as the first stage of theoretical consideration and assessment of the influence of variable factors on the degree of use of additive materials and in order to increase the efficiency of their use, presents a theoretical interpretation and shows the feasibility of taking into account in improved mathematical models the processes of melting (dissolution) and assimilation of solid materials by the metal melt introduced quantitative factor, as one of the significant parameters of complex physical and chemical processes. Using the example of lump ferromanganese grade FeMn78, as an additive material, which was introduced in different quantities (from 0,2 to 2 kg/t) into a ladle with a capacity of 250 tons during metal processing in a ladle-furnace unit (LF) with simultaneous bottom argon purging within the range of 200 – 800 l/min through each of the two tuyeres, the dependence of the influence of the amount of additive on the change in the hydrodynamics of the liquid metal bath is shown.

The aim of the study is to analyze and generalize the properties of slags within the CaO-SiO2-Al2O3-MgO-CaF2 system in different ratios of components and their concentrations, which is the basis of refining slags in modern steelmaking. To ensure the technological functions, the slag melt should have a set of optimal values of physical and chemical properties, in particular: viscosity, surface tension, electrical conductivity, melting temperature (beginning and end), enthalpy, density and others, which significantly affect the kinetics of heat and mass transfer processes in the "metal-slag" system. The information resource of researches is provided by own experimental data and data of databases "Slag" and "SFM" containing information about technological properties of melts of slag and oxide systems. The analysis of the data on the dependence of the properties of oxide systems on their chemical composition and temperature was performed. Oxide systems within the chemical composition CaO-SiO2-Al2O3-MgO-CaF2 are considered. The connection of the chemical composition of slag systems with the properties of their melts from the point of view of the concept of directed chemical bonding using integral parameters is established: ρ is the stoichiometry index; ∆e is the average number of electrons localized in the direction of the cation-anion (K-A) bond; d is the average inter-nuclear distance K-A; tgα is the change in the electron density in the direction of the K-A bond; ZA(A-A), ZK(K-A), ZK(K-K) are the weighted average values of cation and anion charges in the A-A, K-A, K-K bonds. Based on the results of experimental and analytical studies, predictive models of the properties of the considered oxide systems were obtained, namely for the calculation of viscosity, electrical conductivity, crystallization temperature and density of slag melts in the range of their temperatures from 1200°C to 1800°C. The presented method of predicting the properties of refining slags can be used to evaluate the use of slags of different composition in the ladle, for example, in ladle-furnace installations.

Dephosphorisation and desulphurisation are the most important stages of high-quality steel production, characterized by complex physical and chemical processes of interaction in the metal-slag system. The article is devoted to studying the results and evaluating the efficiency of steel refining processes at different stages of its refinement in modern Ukrainian conditions. The aim of the work is to develop a methodology for assessing the physical and chemical interaction in the metal-slag system during steel refining from the perspective of the concept of a cooperative ion exchange process using the parameters of interatomic interaction in melts. As a result of studying the regularities of sulphur and phosphorus distribution depending on the chemical composition of different steel grades from two plants and their corresponding slags, a methodology has been developed that includes the reasonable use of parameters of interatomic interaction in melts as criteria for assessing the degree of completion of ion exchange processes during steel refining. Along with the use of integral physical and chemical parameters of the chemical and charge state of metal and slag melts (chemical equivalent of metal composition ZY(e) and slag Δe(e), effective charge of element Ze(e)), the paper shows the key role of the influence of the "recharge" parameter of the element ΔZе on the process of interfacial distribution of sulfur and phosphorus. This parameter has also shown its efficiency as a criterion for assessing the deviation of the metal-slag system from equilibrium at different stages of steelmaking and finishing at the ladle furnace unit (LFU). The proposed approach makes it possible to assess the level of completion of steel refining processes in order to develop effective technological solutions. In addition, it lays the foundation for solving specific applied problems at a new level, allowing optimizing existing technologies and developing new methods and reagents for producing steels with reduced sulphur and phosphorus content.

Metallurgy is one of the leading sectors of the economy of Ukraine, by 2022 it was be the second largest and profit article of Ukrainian exports. Steelmaking production is the second stage in the total production cycle of ferrous metallurgy. In general, Ukraine is one of the leaders of the steel producers in the world. In 2021, Ukraine took 14 place in the global rating of world manufacturers of steel according to World Steel Association (WSA) data. During 2021 year in Ukraine was produced 21366 thousand tons of steel. In the modern metallurgical industry of Ukraine, the main methods of steel making is the oxygen converter process, Marten process and electrometallurgical process. The ratio in the overall production of steel between these of technological processes changes every year. As of 2017, in Ukraine, the fate of steel produced in converter was 71.7% from total steel produced. Converter process is predominantly using for obtained the common steel marks. Today, there are three large metallurgical enterprises in Ukraine with oxygen converter department in the structure: PrAT "KAMET-STAL", PrAT "ArselorMyttal Kryvyy Rih", PrAT "Dniprovsʹkyy metalurhiynyy zavod". In the structure of which is has 11 converters, a from 60 to 250 tons, adapted to the technology of LD process with the use of multinozzel top tuyere. Steel production with converter process has the potential for further development in the country and increasing it is production. According to the data, produced steel with converter process is the most favorable in cost compared to other basic ways of the steel producing in Ukraine. For example, an electric steel, which is obtained by the process of smelting in arc steelmaking furnaces. The marks of electric steels similar to the converter steel assortment can be more expensive in the range from 7.8% to 95.6%. The marten steel is more expensive than converter steel from 24.5 % to 102.9%. Such data indicate the expediency of predominant use for the common marks of steels the converter process.

Additive manufacturing (AM) is a modern set of technologies that make it possible to quickly and qualitatively create products with a unique geometry that are impossible or difficult to manufacture by traditional methods of production. Currently, researchers pay attention to two major areas, namely AM quality systems and the search for new regularities in already well-known materials that were produced in a traditional way. Internal residual stresses in polycrystalline materials are classified according to three main classes, namely: stress of type I (macrostress), type II (microstress) and type III (intracrystalline residual stress). Accumulation of internal residual stresses generated during the manufacturing process as a result of local heating and cooling (cooling rates from 103 to 108 K/s) can cause damage and possible failure of parts during service. Thus, the reduction of residual internal stresses is considered one of the most urgent and important problems in the field of AM. As a result of the analysis of the works, it was established that during the process of manufacturing parts with the help of SLP, it is actually characteristic that tensile internal stresses develop on the surfaces, which are balanced by compressive internal stresses in the volume. Since the research was carried out on samples of a simple shape, the obtained results are difficult to compare with the details of products of a complex geometric shape, which have significant changes in the geometric dimensions of the cross-section.

Baculovirus entry into the central nervous system of Spodoptera exigua caterpillars is independent of the viral protein tyrosine phosphatase
Authors: Gasque Simone Nordstrand
Published: February 2024

Neuroparasitism concerns the hostile take-over of a host’s nervous system by a foreign invader, in order to alter the behaviour of the host in favour of the parasite. One of the most remarkable cases of parasite-induced host behavioural manipulation comprises the changes baculoviruses induce in their caterpillar hosts. Baculoviruses may manipulate caterpillar behaviour in two ways: hyperactivity (increased movement in the horizontal plane) and/or tree-top disease (movement to elevated levels in the vertical plane). Those behavioural changes are followed by liquefaction and death of the caterpillar. In Autographa californica multiple nucleopolyhedrovirus (AcMNPV)-infected Spodoptera exigua caterpillars, an enzymatic active form of the virally-encoded protein tyrosine phosphatase (PTP) is needed for the expression of hyperactivity from 3 days post infection (dpi). Using eGFP-expressing recombinant AcMNPV strains we show that infection of the caterpillar’s central nervous system (CNS) can be observed primarily from 3 dpi onwards. In addition, we demonstrate that the structural and enzymatic function of PTP does not play a role in infection of the CNS. Instead we show that the virus entered the CNS via the trachea, progressing caudally to frontally through the CNS and that the infection progressed from the outermost cell layers towards the inner cell layers of the CNS, in a PTP independent manner. These findings help to further understand parasitic manipulation and the mechanisms by which neuroparasites infect the host nervous system to manipulate host behaviour.

Despite the implementation of diverse policies and systems by the government aimed at mitigating severe disasters such as deaths, the occurrence of fatal incidents within the construction industry remains alarmingly high, comprising 53% of the industry as a whole. Consequently, this research endeavor was undertaken with the aim of identifying an efficacious approach for KOSHA-MS(Korea Occupational Safety and Health Agency Management System), the pivotal component of the construction site accident prevention system, to enhance its efficacy and effectiveness. In this study, the independent variables were comprised of four human factors and two occupational factors. These variables were constructed based on interviews with forty safety and health management managers, as well as safety managers, from twenty construction sites operated by S Construction. A review of previous research was also conducted. The dependent variable, on the other hand, was the configuration of KOSHA-MS. A survey encompassing a total of 151 construction employees and workers was conducted between 1, November, 2023, and 21, November, 2023. The gathered data underwent statistical analysis utilizing the SPSS program.
The study found that the survey items had good validity and reliability. Additionally, the roles of safety and health managers and management supervisors, were identified as significant human factors, while hazardous work was identified as a significant occupational factor impacting KOSHA-MS. The findings of this study indicate that effective managerial roles and the management of hazardous work take part in a crucial role in the practical and effective implementation of KOSHA-MS.

This study is a quasi-experimental study with a non-equivalent control group pretest-posttest design conducted to determine the effect on knowledge and performance confidence in injection safety by applying an injection safety education program using a mobile application to nursing students. The study subjects were 49 second-year nursing students at a university in C province. Data analysis was performed by using the IBM SPSS 26.0 program. The experimental group was provided with printed materials on injection safety and the mobile application, while the control group was provided with the printed materials only. Both groups were allowed to self-study for seven days. General characteristics were analyzed with descriptive statistics. The homogeneity between the two groups was analyzed using a t-test, χ2 test, Mann-Whitney U test, and Fisher’s exact test, and pre-and post-test differences in knowledge and performance confidence between the experimental and control groups were analyzed with an independent t-test. The experimental group had significantly higher knowledge of injection safety (t=3.07, p=.004) and performance confidence (t=3.53, p=.001) than the control group. In addition, the difference in scores of knowledge (t=2.20, p=.034) and performance confidence (t=3.08, p=.003) in the experimental group significantly improved, compared to the control group. This study identified that the injection safety application was effectively improved nursing students’ injection safety knowledge and performance confidence. In addition, the results of this study will provide substantial evidence for the use of applications as an educational medium for nursing students’ injection safety practices in the future.

Published: February 2024

Anemia in kidney transplant recipients can stem from a diverse array of etiologies, including dietary deficiencies, inflammatory processes, allograft dysfunction, as well as viral and bacterial infections. We present a case of refractory anemia in a 49-year-old male patient occurring within the initial month following a kidney transplant, which persisted despite numerous transfusions, posing a formidable challenge. The patient was maintained on the standard immunosuppressant regimen—Tacrolimus, Mycophenolate, and Prednisolone. Diagnostic evaluations eliminated well-established causes such as dietary deficiencies, gastrointestinal losses, and prevalent infections. Subsequently, after viral PCR testing, a diagnosis of Pure Red Cell Aplasia (PRCA) due to infection with parvovirus B19 was made. Although the patient had a reduction in the immunosuppression drugs and received a course of Intravenous Immunoglobulins (IVIG) on two separate occasions spanning two months, the anemia relapsed. Subsequently, after an additional dose of IVIG with further modification and reduction of the immunosuppressant regimen, including stopping the mycophenolate and switching tacrolimus with cyclosporine, the patient ultimately achieved successful resolution of his symptoms and a significant decrease in viral load. Our case highlights the significance of unconventional etiologies when confronted with anemia in the setting of kidney transplantation. Furthermore, it also provides further insights into therapeutic avenues for addressing PRCA in kidney transplant recipients.

Congenital unilateral absence of the vas deferens
Authors: Owens Winston , Hakim Jonathan
Published: February 2024

Introduction: A 65-year-old male with a known history of unilateral renal agenesis was found to have concurrent absence of the vas deferens ipsilaterally.

Case Report: The patient presented with organic erectile dysfunction and wanted to proceed with surgical management. Routine pre-operative evaluation confirmed history of a left solitary kidney, and physical exam revealed absence of the right vas deferens. Previous imaging confirmed right renal agenesis, and with subsequent absence of the right vas deferens noted on physical exam, this confirmed embryological arrest as the cause of the anatomic abnormality.

Conclusion: Congenital unilateral absence of the vas deferens (CUAVD) is an uncommon finding that is largely found during infertility evaluations and vasectomy consults. It is important to understand genetic components and embryological origins of CUAVD to appropriately evaluate patients for additional defects.

Food allergy prevention: where are we in 2023?
Authors: Venter Carina , Smith Peter K. , Fleischer David M.
Published: February 2024

Food allergy prevention involves recommendations to the maternal diet during pregnancy and breast feeding, early life feeding and introduction of solid foods. Pregnant and breastfeeding women are not recommended to exclude any food allergens from their diet, but data are lacking to support active consumption of food allergens for prevention of food allergy. Breastfeeding is recommended for the many health benefits to the mother and child but has not shown any association with reduction in childhood food allergies. There is currently no recommendation regarding the use of any infant formula for allergy prevention, including the use of partially or extensively hydrolyzed formulas. Once the introduction of solid food commences, based on randomized controlled trials, it is advised to actively introduce peanuts and egg early into the infant diet and continue with consumption of these. Although there are limited data with respect to other major food allergens and whether early introduction may prevent allergy development, there is no need to delay the introduction of these allergens into the infant diet. Interpreting food allergen consumption in the context of cultural food practices has not been studied, but it makes sense to introduce the infant to family foods by 1 year of age. Consumption of foods typical of the Western diet and foods high in advanced glycation end products may be associated with an increase in food allergies. Similarly, intake of micronutrients, such as vitamin D and omega-3 fatty acids in both the maternal and infant diet, needs further clarification in the context of food allergy prevention.
