Interval traffic analysis of multichannel queuing systems
Authors: Likhttsinder Likhttsinder Ya. , Privalov Alexander Yu.
Published: August 2023

The passage of streaming video traffic through the backbone switch of the communication node is considered. The features of video traffic, which has a pronounced burst character, are analyzed. The influence of the characteristics of such flows on the sizes of queues in the nodes of telecommunication networks is studied. The results of analytical consideration and simulation modeling are presented. The generalized Khinchin-Pollachek formula is considered and for group flows a linear dependence of the numerator of this formula on the load factor is shown. It is shown that, in contrast to Poisson flows, the queue sizes in multichannel queuing systems with video traffic flows practically do not decrease with an increase in the number of channels.
Modelling and control of hydrogen production processes based on electrolysis
Authors: Mironov Egor A.
Published: August 2023

Currently, hydrogen is considered as one of the most promising energy carriers, the production of which is possible from various raw materials, including water, natural gas, hydrogen sulphide, coal, etc. The article presents the main results of an analysis of global technological trends in the development of hydrogen generation methods in the period from 2010 to 2038, which aims to identify in-demand and popular technological solutions for hydrogen energy. The analysis is based on the International Energy Agency's database published in October 2022, which contains the most comprehensive information on the key characteristics of 990 hydrogen projects based in sixty countries: output, installed electrical power, carbon dioxide emissions, type of output, stage and timing of implementation. The analysis shows the steady leadership of electrolysis hydrogen generation technologies in the context of the search for the most widespread method of hydrogen production. At the same time, the global hydrogen energy industry has clearly expressed trends towards the increased introduction of alternative (non-electrolysis) technologies in large-scale industrial production. Based on the existing empirical Ullerberg model, a modified universal structural simulation model of hydrogen electrolysis generation in plants with alkaline electrolysers and with proton exchange membrane has been proposed. The modified model has been developed in MATLAB application package and Simulink dynamic simulation environment using Simscape physical simulation elements. Verification procedure of the developed model showed good agreement of simulation results with the experimental data available in the open sources and obtained at the alkaline electrolysis and proton exchange membrane electrolysis plants. To increase the energy efficiency of hydrogen production process, a single-loop system for automatic regulation of feed water temperature supplied to the proton-exchange membrane electrolysis unit was developed.
Goethes "Märchen" und Essays zur "Spiraltendenz" – eine posthumanistische Lektüre
Authors: Gries Ines
Published: August 2023

Das Märchen ist der Abschluss von Goethes Erzählzyklus Unterhaltungen deutscher Ausgewanderten und als unlösbares Rätsel angelegt. In dieser Eigenschaft bietet es sich als experimenteller Verhandlungsort epistemologischer Grundsatzfragen an, wie sie in jüngster Zeit von kritisch-posthumanistischen Theorien formuliert werden. Die Figuren der Irrlichter und Schlange dieses Textes von 1795 repräsentieren in dem hier vorliegenden Versuch Goethes Kritik am wissenschaftlichen Systemdenken um 1800, für welches er mit zwei späten Aufsätzen zur Spiraltendenz 1831 eine Alternative zu konzipieren weiß. Ausgehend von Fragen des Einflusses auf Theoriebildungen der Gegenwart, zeigen sich Goethes wissenschaftskritische Überlegungen damit erstaunlicherweise in nächster Verwandtschaft zu Forderungen nicht-anthropozentrischer Erkenntniskonzepte.

Commemorating Madison Grant in California State Parks
Authors: McIntosh David G.
Published: August 2023

A memorial in Prairie Creek Redwoods State Park in Northern California continued to honor the name of Madison Grant (1865–1937) until 2021. De Forest Grant (Madison’s younger brother), John D. Rockefeller Jr., the New York Zoological Society, and others dedicated the monument in 1948. Madison Grant’s most well-known book, The Passing of the Great Race (1916), became the basis for monumental atrocities leading up to and during World War II. This article explores Grant’s racist legacy and claims he made that successfully convinced lawmakers to pass legislation restricting the rights of non-White peoples and immigrants. His book and the ideas it contained continue to serve as a basis for hate and exclusion in the United States.

Approach to Hyperamylasemia and Hyperlipasemia
Authors: Lee Se Hee , Cho Woohyun , Yang Min Jae
Published: August 2023

Hyperamylasemia and hyperlipidemia occur when the amounts of amylase and lipase that enter the blood overweigh the kidney and liver reticuloendothelial system clearance of the enzymes. In normal homeostasis, most of these enzymes are excreted from the apical membrane of the acinar cells into the ductal system of the gland. However, in pathological conditions, this apical exocytosis is blocked, and the leakage of these enzymes at the basolateral membrane is increased. Therefore, these enzymes are released into the bloodstream. Many different pancreatic pathologies and Gullo syndrome can cause this type of leakage in the pancreas. This mechanism can also cause basolateral leakage in other organs that secrete amylase and lipase. In small bowel inflammatory conditions, amylase and lipase are absorbed through the inflamed mucosa and introduced into the bloodstream due to increased vascular permeability. Regardless of the enzymes that enter the blood circulation, several kidney and liver diseases prevent the excretion and metabolism of serum amylase and lipase. When the amylase and lipase are combined with immunoglobulins, they escape normal glomerular filtration due to the development of macroenzymes and accumulate in the blood. These situations related to the clearance of the enzymes are also crucial mechanisms of serum enzyme elevation that should not be overlooked.

Angle-independent cellulosic photonic crystals for smart and sustainable colorimetric sensing
Authors: Xie Mingzhen , Chen Junjie , Zhang Tiantian , Sun Xiaohang
Published: August 2023

Cellulose nanocrystals, as well as hydroxypropyl cellulose, can form lyotropic liquid crystals, which can be processed into pigments or glitter products for sustainable coloration. Some stimuli-responsive polymers or nanoparticles are expected to form colorimetric sensors via co-assembly with these cellulosic photonic crystals. The co-assembly behavior of CNCs with polymers is determined by the hydrogen bonds and physical adsorption. Thus, adjusting the molecular chain structure, hydrophilicity, and electrostatic interaction of co-assembled polymers can lead to flexible and tunable colorimetric cellulosic sensors. Despite the advantages of cellulose-based amorphous photonic crystal (APC) pigments or glitters as sustainable and visually captivating sensors, there are still problems in efficient preparation and co-assembly conditions. This editorial will provide a brief discussion of the benefits, applications, and challenges of cellulose-based APCs.
Establishing a Fetal Center in a Freestanding Pediatric Hospital
Authors: Ogunleye Oluseyi , Johnson Mickey , Stocker Christy , Texter Karen , Seabrook Ruth , Etchegaray Adolfo , Olutoye Oluyinka
Published: August 2023

Advances in antenatal imaging have allowed early and accurate diagnosis of many fetal anomalies. This, together with the increasing understanding of the natural history of many fetal diseases, has opened the door to the possibility of offering timely fetal interventions in progressive or life-threatening conditions with the intention of improving perinatal outcomes. These interventions can occur at an adult hospital with obstetrical services (with or without pediatric care) or at a freestanding pediatric hospital. In this article, we provide an overview of the approach to develop a comprehensive fetal care center in a freestanding pediatric hospital. Services included prenatal consultation, advanced diagnostics, innovative fetal therapy, research, and special delivery services. We also review the importance of continuous improvement in achieving this goal.
In Utero Presentation of Left Ventricular Aneurysm
Authors: Ansah Deidra A. , Lawrence Emily J. , Kearney Debra L. , Qureshi Athar M.
Published: August 2023

Congenital left ventricular aneurysm, pseudoaneurysm, and diverticulum are rare entities. These diagnoses can be made pre- and/or postnatally. Although these entities overlap clinically and morphologically, important distinctions can allow for accurate diagnoses. Appropriate diagnosis can be imperative for risk stratification and guidance of prenatal and postnatal management. The case described in the present report highlights a challenging case of a fetal left ventricular aneurysm, management during the prenatal and postnatal periods, and important differentiating features from a ventricular diverticulum and pseudoaneurysm.
Outdoor Cold Air Versus Room Temperature Exposure for Croup Symptoms: A Randomized Controlled Trial
Authors: Siebert Johan N. , Salomon Coralie , Taddeo Ilaria , Gervaix Alain , Combescure Christophe , Lacroix Laurence
Published: August 2023

OBJECTIVES

Croup is the most common cause of acute upper airway obstruction in children. The benefits of treating croup with steroids are well established, with an onset of effect 30 minutes after administration. We investigated whether a 30-minute exposure to outdoor cold air might improve mild to moderate croup symptoms before the onset of action of steroids.

METHODS

This open-label, single-center, randomized controlled trial, enrolled children aged 3 months to 10 years with croup and a Westley Croup Score (WCS) ≥2 attending a tertiary pediatric emergency department. Participants were randomized (1:1) to either a 30-minute exposure to outdoor cold (<10°C) atmospheric air or to indoor ambient room air immediately after triage and administration of a single-dose oral dexamethasone. The primary endpoint was a decrease in WCS ≥2 points from baseline at 30 minutes. Analyses were intention to treat.

RESULTS

A total of 118 participants were randomly assigned to be exposed to outdoor cold air (n = 59) or indoor room temperature (n = 59). Twenty-nine of 59 children (49.2%) in the outdoor group and 14 of 59 (23.7%) in the indoor group showed a decrease in WCS ≥2 points from baseline at 30 minutes after triage (risk difference 25.4% [95% confidence interval 7.0–43.9], P = .007). Patients with moderate croup benefited the most from the intervention at 30 minutes (risk difference 46.1% [20.6–71.5], P < .001).

CONCLUSIONS

A 30-minute exposure to outdoor cold air (<10°C), as an adjunct to oral dexamethasone, is beneficial for reducing the intensity of clinical symptoms in children with croup, especially when moderate.

Resucitar a Kāla: tiempo que muere y tiempo que mata en los Purāṇas
Authors: Ferrández Formoso Raquel
Published: August 2023

El dios Śiva encarna el tiempo y la inmortalidad, el deseo y la sublimación del deseo, la muerte y el poder que el yogui tiene para conquistarla; por ello, el dios de los ascetas es a un tiempo el límite que impone la naturaleza y el poder oculto en esa misma naturaleza, capaz de sobrepasar sus propios límites. Kāla, el dioshindú del tiempo, nos hace madurar y luego nos engulle, devorándose a sí mismo. Pero también puede morir por un golpe de impaciencia, cuando despierta la furia ígnea del dios Śiva, vencedor de la muerte (mṛtyunjāya) y señor del tiempo (mahākāla). Cuando esto sucede, los mortales le imploran a Śiva que le devuelva la vida, pues el tiempo es sinónimo de aliento vital (prāṇabhuta). La literatura purāṇica muestra,a lo largo de tramas narrativas solidarias, las reacciones contrarias que suscita en nosotros la experiencia del tiempo: cuando Kāla se asocia con Māyā, puede hacer que experimentemos un instante como si fuesen años. Además, la experiencia cíclica de la reencarnación invierte el orden lógico de las relaciones, pues el niñopuede ser más sabio, por más viejo, que sus propios padres.
yoga perfecto: La historia de Śuka en el Mahābhārata
Authors: Figueroa Óscar
Published: August 2023

Este artículo investiga la interrelación de dos matrices de representación del yoga en el Mahābhārata: como un poder mágico para dominar la realidad; como una técnica para morir en una actitud de renuncia emancipativa. Para ello, se analiza la historia del joven Śuka (12.309-320). Con base en una selección de pasajes, traducidos por primera vez al español, se muestra que la historia integra visiones distintas sobre el yoga de camino a una imagen de totalidad armónica, en la que la narrativa desempeña un papel crucial, ignorado a la fecha. Así, concebido como modelo de perfección, el yoga de Śuka constituye un caso inmejorable para explorar las relaciones entre yoga, filosofía y literatura en la India clásica.

Este artículo pretende ser una breve introducción a la crítica de la economía política de género de Roswitha Scholz en el contexto de las nuevas lecturas de El capital. En un primer momento se analiza la crítica de Moishe Postone al marxismo tradicional, para comprender el sentido de la crítica de Roswitha Scholz al feminismo marxista tradicional. Se muestra, con ello, el objetivo de la teoría de Scholz: validar la categoría de género como una categoría central del capitalismo y central para pensar la opresión de las mujeres. Posteriormente se exponen y analizan los elementos centrales de la teoría de la forma valor/escisión de Roswitha Scholz. Por último, se evalúan las implicaciones de la teoría de Roswitha Scholz para comprender la opresión de las mujeres en el capitalismo.

Sobre el antimaterialismo de la forma valor (y sus teorías). Naturalismo ontológico y límites a la dialéctica del capital
Authors: Martín Facundo Nahuel
Published: August 2023

Trataré de articular la teoría antinaturalista de la forma valor con el naturalismo ontológico eco-marxista. Retomaré la dialéctica sistemática de Christopher Arthur. Como es no-total, esta dialéctica remite a algo externo al valor, incluida la naturaleza. La teoría antinaturalista del valor, así, puede situarse en un marxismo ecológico ontológicamente naturalista.
¿Qué hacer con los escritos de Marx sobre arte y estética? El modo de presentación y sus límites
Authors: Durán Medraño José María
Published: August 2023

Los fragmentos de Marx sobre arte y estética son un problema teórico. En el texto se sostiene que las lecturas realizadas hasta la fecha de estos fragmentos no le hacen justicia al edificio teórico de Marx. Se propone leer a Marx de una manera que nos haga reflexionar acerca de la necesidad de abrir un nuevo campo de investigación. Para ello, se hace uso de los conceptos y categorías que Marx desarrolla en la crítica de la economía política de una manera que completa los fragmentos de arte y estética y los transforma en una teoría materialista del arte.

Racionalidad y ética en Franz Hinkelammert: La crítica hinkelammertiana a la teoría ortodoxa de la acción racional
Authors: Mora Jiménez Henry
Published: August 2023

El artículo desarrolla la distinción fundamental que establece Franz Hinkelammert entre racionalidad instrumental medio-fin y racionalidad reproductiva de la vida, y por qué la primera (sin negar su estatus teórico y práctico) debe supeditarse a la segunda. Se distinguen tres tipos de juicios: juicios medio-fin, juicios vida-muerte y juicios de valor. Solo si descartamos los juicios vida-muerte (que son juicios de hecho), los juicios de valor resultan ser ajenos a la discusión científica, ya que serían vistos como simples juicios de gusto. A partir de lo anterior se plantea otra distinción fundamental entre éticas funcionales y ética para la vida. Esta última resulta crucial para el estudio de las consecuencias del actuar humano sobre las condiciones de posibilidad de la vida.

Feminismos multiespecies: ecofusión entre cuerposterritorios. Una crítica a la colonización de la naturaleza desde una “poética erótica de la relación”
Authors: Bidaseca Karina
Published: August 2023

El texto explora las relaciones de cuidado interespecífico con el mundo vegetal, para cuestionar el ecocidio que afecta a los cuerpos/territorios y a los conocimientos ancestrales tomando la práctica performativa de land art de la artista cubana Ana Mendieta con su cuerpo como primer territorio desde una “poética erótica de la relación”, inspirado en Audre Lorde y Édouard Glissant. Considera nuestro cuerpo como locus de experimentación constante en las luchas descoloniales de agencias humanas y no humanas (fotofilia o amor por las plantas), para apelar a una justicia multiespecie (Haraway).

El presente artículo sintetiza elementos literarios y teológicos contenidos en los relatos conocidos como “la pasión” de Jesúsen los evangelios canónicos. A partir de una ubicación en el género narrativo y en la labor de la memoria como reconstrucción selectiva, se presentan las principales conclusiones que la historiografía y la exégesis contemporáneas han obtenido de los textos que se refieren a la muerte de Jesús para, finalmente, comprender los mismos como narraciones rituales primitivas que responden a la degradación sufrida por la muerte ignominiosa y repentina de su líder en la cruz.
estudos decoloniais e as interfaces entre extensão e pesquisa na formação de pesquisadores
Authors: Poso Fabiana de Freitas , Monteiro Bruno Andrade Pinto
Published: August 2023

Usualmente a extensão universitária se manifesta como prestação de serviços de caráter assistencial ou mercantil, reproduzindo, assim, a visão de mundo do colonizador. No entanto, ela deveria ser sinônimo de aproximação entre a universidade e a sociedade, de democratização dos saberes, de transformação social e de retroalimentação nas mudanças das universidades. Desta forma, foi elaborado um curso de extensão a partir da interação de três grupos de pesquisas que estão interligados pelos estudos decoloniais, com o escopo de auxiliar na formação dos seus respectivos organizadores e de possibilitar o reconhecimento e a compreensão dos cursistas dos principais conceitos e temas decoloniais, contextualizando, assim, com suas práticas e atribuindo estas informações às suas atividades profissionais. Foram realizadas entrevistas com os organizadores, tomando como pilar a Análise de Conteúdo, demonstrando que embora tenha sido um grande desafio, foi um momento ímpar de aprendizagem, de trocas e de aproximação com grandes pesquisadores desta temática.
Investigation of the stability of one difference equation with complex coefficients
Authors:   Perm National Research Polytechnic University, Aksenenko Ilya
Published: August 2023

We study the stability of a linear autonomous difference equation with two (generally speaking, complex) coefficients. The starting point of the study is the Schur-Kohn theorem on the location of the roots of the characteristic equation with respect to the unit disk in the complex plane. To construct the domain of exponential stability in the parameter space, we use the D decompodition method, which consists in constructing curves (or surfaces) such that the number of roots of the characteristic equation outside the unit disk changes when passing through the curves; then the area is determined, which corresponds to the zero number of such roots; this is the area of stability. We implement this scheme for the above difference equation: geometric stability criteria are found and the domains of exponential stability in a four-dimensional space of coefficients are described, as well as their three-dimensional, two-dimensional and one-dimensional sections. The Lyapunov stability is studied separately, which is corresponded by the domain of exponential stability supplemented by a part of its boundary. To describe Lyapunov stability exactly we use a "multiplicity curve", which is a line such that all its points correspond to multiple roots of the characteristic equation. In addition, we find and construct a domain of absolute stability with respect to one of the parameters of the initial equation. For this domain, we formulate criteria of exponential stability and Lyapunov stability.The results obtained can be applied to the study of processes in physics, technology, economics, biology, which are modeled using discrete models in the form of difference equations.
Valuation of used machinery based on the new model of its degradation
Authors:   Central Economics and Mathematics Institute of Russian Academy of Sciences, Smolyak Sergey
Published: August 2023

We propose a new model of equipment degradation. In it, the machine is subjected to random latent failures, the danger of which depends on the equipment condition and after each failure the intensity of the equipment's benefits decreases by a random amount. Equipment that brings negative benefits is subject to decommissioning. The model parameters are found based on known information about the average value and the coefficient of variation of the equipment lifetime. Market value of equipment is determined by discounting the flow of benefits from its future use. This allows us to find the dependence of the equipment’s market value on the benefits it brings. Assessing the market value of new equipment is usually not difficult, but it is much more difficult to do this for used equipment items. Appraisers are usually unable to estimate the value of the work performed by equipment, and when valuing a used equipment, they have to rely on its age. To do this, the market value of a similar new equipment is usually reduced by a depreciation factor or multiplied by Percent Good Factor (PGF, relative value), depending on the age of equipment being valued. However, equipment of the same age may be in different conditions and, therefore, have a different market value. Therefore, such PGFs, in fact, relate to the average equipment that has survived to the appropriate age. Appraisers determine them by formulas or tables that are usually not supported by proper justifications. The proposed model makes it possible to build the dependence of the average PGF on age and calculate the market value of the work performed by machines, even if such works are not traded on the market. It turns out that it is possible to take into account the influence of the utilization cost of the machine and inflation in the model. The results of experimental calculations performed using the model (with calibration parameters selected appropriately) are in good agreement with the market prices of some types of construction equipment.
Survival of Four Conical Implant Abutment Connections After Removal of the Abutment Screw and Simulated Cyclic Loading: An In Vitro Comparative Study
Authors: Yao Kuang-Ta , Chang Tsai-Yu , Huang Guan-Jhong , Fang Hsu-Wei , Wang Ding-Han , Hsu Ming-Lun
Published: August 2023

This in vitro study evaluated the mechanical behavior of different conical connection implant systems after abutment screw withdrawal. Four conical connection systems were selected based on different conical half-angles: Ankylos (5.7°), Cowell (7.0°), Straumann (7.5°), and Astra (11.0°). In each system, 5 implants and abutments were used (n = 5). According to the recommended value, each abutment screw was torqued to settle the abutment and then withdrawn through a predesigned hole of the cemented crown. The retentiveness of the abutment was evaluated by the following mechanical testing. All specimens were subjected to cyclic loading of 20–200 N, 30°, and 4-mm off-axis to the implant axis, for 106 cycles. The pullout forces and axial displacements of the abutments were measured. The data of the Cowell system was obtained from our previous work. All groups other than Astra group, in which abutment loosened after abutment screw withdrawal, passed the cyclic loading test. Straumann group demonstrated a significantly lower pullout force (27.4 ± 21.1 N) than Ankylos (160.1 ± 41.4 N) and Cowell (183.7 ± 30.5 N) groups. All groups showed abutment rebound after screw withdrawal except Straumann group. In addition, Ankylos, Cowell, and Straumann groups demonstrated axial displacement after cyclic loading. In terms of the retentiveness of the abutment after abutment screw withdrawal examined in this study, Ankylos and Cowell groups had much higher retentiveness than Straumann group, while Astra group had none. Conical angle could be a key design parameter to make abutment screw withdrawal after conical abutment settlement feasible, but more studies must be conducted for clinical application.

Authors: Shariff Jaffer Ahmed , Gurpegui Abud Daniela , Bhave Manasi B. , Tarnow Dennis P.
Published: August 2023

Selective serotonin reuptake inhibitors (SSRI) are commonly prescribed to treat mental health disorders, and previously published literature, although scarce, has shown a significant association between SSRI use and dental implant failure. This systematic review and meta-analysis aimed to examine whether such an association exists and, if so, to determine its strength. Reviewers performed an extensive search of the literature, last accessed in June 2022 in PubMed/Medline, Embase, and Cochrane databases using MeSH terms. Retrospective and prospective observational cohort and experimental studies evaluating the role of SSRI on dental implant failure among individuals ≥18 years of age, with a minimum follow-up of 6 months after implant placement, were deemed eligible. The search yielded a total of 6 eligible studies, all retrospective cohorts. Statistical analyses were performed using the statistical software R 4.1.3. Results showed higher implant failure rates among SSRI users vs non-SSRI users at both the patient level (5.6%–19.6% vs 1.9%–8.0%) and the implant level (5.6%–12.5% vs 1.9%–5.8%). The pooled relative risk (RR) of implant failure was more than double among SSRI users at the patient level (pooled RR: 2.44, 95% confidence interval [CI]: 1.68–3.55, P < .01) and at the implant level (pooled RR: 2.34, 95% CI: 1.74–3.15, P < .01) compared with non-SSRI users. DerSimonian and Laird estimates showed homogeneity of the studies (I2 = 0%, P > .05), and funnel plots and Egger’s test determined no publication bias across all selected studies at both patient and implant levels. In conclusion, SSRI use is significantly associated with higher implant failure. Providers should be aware of this association and educate patients on the risk of implant therapy when obtaining informed consent.

Published: August 2023

This paper is to characterize $L$-concavities and $L$-convexities via some derived forms of relations and operators. Specifically, notions of $L$-concave derived internal relation space and $L$-concave derived hull space are introduced. It is proved that the category of $L$-concave derived internal relation spaces and the category of $L$-concave derived hull spaces are isomorphic to the category of $L$-concave spaces. Also, notions of $L$-convex derived enclosed relation space and $L$-convex derived hull space are introduced. It is proved that the category of $L$-convex derived enclosed relation spaces and the category of $L$-convex derived hull spaces are isomorphic to the category of $L$-convex spaces.
A note on CSP rings
Authors: MA Haitao , SHEN Liang
Published: August 2023

A ring $R$ is called right CSP if the sum of any two closed right ideals of $R$ is also a closed right ideal of $R$. Left CSP rings can be defined similarly. An example is given to show that a left CSP ring may not be right CSP. It is shown that a matrix ring over a right CSP ring may not be right CSP. It is proved that $\mathbb{M}_{2}(R)$ is right CSP if and only if $R$ is right self-injective and von Neumann regular. The equivalent characterization is given for the trivial extension $R\propto R$ of $R$ to be right CSP.

This article presents the results of a study of the quality indicators of flour streams, which affect the formation of the water absorption capacity of the final flour. The studies were carried out on five mills with a productivity of 60 to 300 tons per 24 hours. With the help of an original technique for removing the quantitative balance of the milling process, the yield of each individual flour stream and the yield of the final flour were determined, which depended on the productivity of the mill and varied from 75.9-76.1% – for mills with low productivity to 79.0-80.6% – for mills with productivity above 150 tones per 24 hours. Significant changes in the quality indicators of flour streams have been established. During milling at the mill plant with productivity of 150 t / 24 h ash content increased from 0.39% to 2.21%, protein content – from 11.0% to 17.4%, starch damage – from 17.6 UCD to 32.5 UCD. As result the water absorption capacity increases during the milling process from 54.0 to 69.6%. The variation in ash content, protein content, starch damage and other properties of the mill streams are due to the anatomical parts they come from, as result it influence the quality of the final flour. A simple correlation analysis carried out made it possible to evaluate the effect of ash content, protein content, and damaged starch content on the evolution of water absorption capacity. The variations of starch damage and ash content in the flour streams seems to be the principal factor of the increase in water absorption variation, while protein content has the least influence. Despite fluctuations in flour quality indicators on individual systems, it was found that strongly determines the overall quality of the final flour is the mill stream flour yield. That’s why optimization of grinding and sieving modes of systems (B1, B2, C1, C2, B3, Siz1) which have flour streams with the highest yield and the greatest impact on the grinding process is a fundamental step in achieving the set values for the final flour quality indicators. Knowledge and understanding of the patterns of change on individual systems of values of flour yield and their quality indicators that affect water absorption capacity will allow to more effectively manage the water absorption capacity. This will make it possible to optimize the properties of the dough according to the requirements of specific technological lines and to regulate the quality of the finished product at bakery and confectionery enterprises.

The history of the pseudo-Apostles movement has come down to our time in the presentation of those who defeated them. The personalities of Gerard Segarelli and Fra Dolcino, the leaders of the pseudo-Apostles movement, can also be considered from the perspective of the presence of elements inherent in the lifetime cult of saints in the dogmatic Christian understanding, which are similar to the worship cults formed around the leaders of religious associations in the XIII-XIV centuries.

Published: August 2023

In this paper, the question of whether the efforts of businesses on environmental, social and corporate governance (ESG) investments are also reflected in their financial performance is tried to be answered. In this context, the effects of ESG scores of non-financial firms between 2009-2019 on market-based and accounting-based performance indicators were examined. According to the findings, ESG scores positively affect the performance indicators of companies. According to the results of the additional analyzes using the sub-components of the ESG, it was found that while all three components of the environmental dimension affect performance positively, some sub-components related to the social and corporate governance dimensions are not statistically related to performance.

Pipe cleaning is currently the most effective method to improve the cleanliness and corrosion resistance of pipes. In this paper, a new method of pipe cleaning is proposed, combining mechanical and chemical cleaning, offline tank cleaning and online cycle cleaning. Through experiments and characterization of the morphology changes, the mechanism of pickling and passivation of Q235 steel was explored, and the entire process of microstructure and morphology changes on the pipe wall’s surface was analyzed to verify the feasibility of this technology. The cleaning process was optimised using response surface analysis to determine the optimum cleaning conditions. This study is of great relevance to the effective operation of continuous-casting equipment over a long period of time.
INFLUENCE OF THE THERMAL CONDITION OF STEEL ON THE TRANSFORMATION TEMPERATURES OF TWO CHROMIUM HOT-WORK TOOL STEELS
Authors: Balaško Tilen , Medved Jožef
Published: August 2023

The influence of the thermal condition of the steel on the transformation temperatures of two chromium hot-work tool steels was investigated. The steels studied were in two different thermal states: the soft -annealed state and the hardened-and-tempered state. The soft-annealed condition, i.e., the fully annealed condition, is a thermal state of steels in which the matrix is ferritic, and the carbon is chemically bonded in spherical carbides. The hardened-and-tempered condition, on the other hand, means a fully hardened-and-tempered martensitic matrix with uniformly distributed (primary and secondary) carbides. The samples were analysed in a simultaneous thermal analyser (STA) using the differential scanning calorimetry (DSC) method to determine the transformation temperatures. We also performed calculations based on the CALPHAD method to obtain the equilibrium temperatures of the transformations. The aim of the study was to determine the influence of different thermal conditions of chromium hot-work tool steels on the transformation temperatures such as solidus/liquidus temperatures, eutectoid transformation temperatures (A1 and A3), austenite solidification temperature and martensite transformation start temperatures. Since DSC analysis also measures thermal influence, we were able to determine the energies absorbed during eutectoid transformation and melting (endothermic processes) and the energies released during the solidification of δ-ferrite and γ-austenite (exothermic processes), as well as the energies released during martensite transformation. It was found that hardening and tempering reduce both eutectoid transformation temperatures and that the solidification intervals are closer to those calculated. From an energetic point of view, hardening and tempering reduce the energies absorbed during melting.
