Authors: Ibrahim Anas , Ahmad Azura , Azuddin Fitri Muhammad Luqman , Yahaya Noryani Natasha , Kamarudin Faizah , Abdullah Muhammad Sofian
Published: October 2023

The conventional geotechnical investigation method using borehole drilling and sampling was usually performed for subsurface exploration. However, it is -time-consuming, invasive and requires the closing of railway lanes that disrupts the train service. To avoid this problem, a geophysical method is an alternative that can be proposed to assess the conditions of the soil subgrade under the railway track. Electrical resistivity is one of the geophysical methods that study the nature of the electricity flow in the soil by injecting the electric current into the soil and measuring the generated potential difference. The field investigation was conducted at two different locations using electrical resistivity methods to identify the properties of the soil. Two railway track site locations selected were Pinang Tunggal, Pulau Pinang (KM 23), and Alor Setar, Kedah (250 m from the station in the north direction). ABEM Terrameter LS was used in field work that applied two configurations of an array, the Wenner and Schlumberger arrays, to infer the subsurface soil layer. The results concluded that the apparent resistivity data need to be inverted into an actual resistivity data set using Resistivity 2D Inversion (RES2DINV) software. The analysis found that the soil properties are both classified as soft soil with electrical resistivity values ranging from 0 - 100 Ω-m.

Published: October 2023

Fly ash-bottom ash of coal is a solid waste in many industries and electric power plants. One method to reduce that solid waste is by using it to produce artificial zeolite. The Filicium decipiens charcoal was added into artificial zeolite to increase its performance to adsorb water pollutants. The pumice stone is also used in this work as a source of silica. The manufacture of artificial zeolite was carried out by the hydrothermal method by optimizing the composition of sodium silicate from Lampung pumice silica, sodium aluminate from aluminum scrap, and charcoal of Filicium decipiens. From the characterization of the LCR meter, the optimum artificial zeolite obtains the conductivity value from 9.14×10-6 (S/cm) to 6.09×10-6 (S/cm), confirming that artificial zeolite is a semiconductor material. The highest conductivity of artificial zeolite will increase its performance as a catalyst and absorbent. The composition of the artificial zeolite after XRF characterization was aluminum, silica, phosphorus, potassium, calcium, titanium, vanadium, chromium, Mangan, and ferrite. From the XRD characterization result obtained, the dominant phase is Zeolite-A. SEM-EDX characterization results obtained a spherical and cylindrical microstructure of artificial.
Representaciones visuales de la magia renacentista
Authors: Pap Betsabé
Published: October 2023

El objetivo de este trabajo es analizar una serie de representaciones pictóricas renacentistas con el fin de indagar tanto en su poder para legitimar cierto pensamiento mágico —nos centraremos en su deriva astrológica—, como, sobre todo, para adentrarnos en su capacidad para deslegitimar a la llamada magia popular, mediante la producción del estereotipo de la bruja lujuriosa, demoníaca y herética. Para ello problematizaremos la eficacia de las imágenes como dispositivos capaces de influir sobre las acciones del espectador, y para afianzar y reproducir ciertas relaciones de fuerza. Indagaremos asimismo en las complejas relaciones que se dieron entre la construcción visual de la imagen de la bruja, su concepción conceptual —tal como aparece en un texto clásico renacentista para la caza de brujas: el Malleus Maleficarum—, y el contexto de producción y circulación de las obras analizadas.

Música popular en dictadura
Authors: Rocha Alonso Amparo
Published: October 2023

En el marco de una investigación sobre políticas culturales en Brasil y en Argentina entre 1964 y 1985, nos proponemos analizar la producción de la música popular argentina, teniendo en cuenta las relaciones de tensión existentes entre tradición y renovación, tanto desde el punto de vista musical como poético. Consideraremos particularmente, a los fines del análisis, la música popular para escuchar, aquella compuesta por autores a partir de materiales populares para una situación de concierto (Fischerman, 2004).2 Arriesgaremos una comparación con lo sucedido en Brasil por la misma época. La hipótesis es que en ambos países la música popular vio afectado su desenvolvimiento por las interrupciones de la vida institucional democrática.

Untargeted metabolomic profiling of dogs with myxomatous mitral valve disease and congestive heart failure shows metabolic differences associated with the presence of cardiac cachexia
Authors: Freeman Lisa M. , Rush John E. , Karlin Emily T.
Published: October 2023

OBJECTIVE

To determine the effects of cardiac cachexia on the metabolomic profile in dogs with myxomatous mitral valve disease (MMVD).

ANIMALS

3 groups of dogs with MMVD enrolled between November 30, 2018, and April 7, 2022: (1) Dogs with congestive heart failure (CHF) and cachexia (CHF-cachexia group; n = 10); (2) dogs with CHF that had no cachexia (CHF-no cachexia group; n = 10); and (3) dogs with asymptomatic disease (American College of Veterinary Internal Medicine [ACVIM] Stage B2) with no cachexia (B2 group; n = 10).

METHODS

Metabolomic profiles were analyzed from serum samples using ultra-high-performance liquid chromatography-tandem mass spectroscopy. Dogs in the 3 groups were compared, with statistical significance defined as P < .05 with a low false discovery rate (q < .10) and nominal statistical significance defined as P < .05 but q > .10.

RESULTS

Numerous metabolites were significantly (n = 201) or nominally significantly (n = 345) different between groups. For example, when comparing the CHF-cachexia vs CHF-no cachexia groups, lipids were the predominant metabolite differences, including many medium- and long-chain dicarboxylates and dicarboxylate acylcarnitines. For comparisons of the CHF-cachexia vs B2 groups and the CHF-no cachexia vs B2 groups, amino acids, nucleotides, and cofactors/vitamins were the predominant metabolite differences.

CLINICAL RELEVANCE

Some significant metabolite differences were identified between dogs with and without cardiac cachexia.
Oh What Tangled Webs We Weave—Unpacking (and Unpicking) the Majority Opinion in Dobbs, State Health Officer of the Mississippi Department of Health et al. v. Jackson Women's Health Organization et al.
Authors: Loveland Ian
Published: October 2023

This paper evaluates the majority judgment in the United States Supreme Court in Dobbs v. Jackson Women's Health Organization. It is suggested that much of what is said in the majority opinion ostensibly appears eminently defensible if viewed solely from a narrowly legalistic perspective. But closer analysis suggests that the majority's reasoning has some weaknesses when viewed within that limited paradigm. A further line of inquiry assesses whether adopting such a ‘legalistic’ approach to the question of abortion rights is in any event an appropriate position for the Court to adopt. The final section of the paper explores two additional contextual issues: the first relates to the personal ethical integrity of some of the majority judges; the second to the adequacy of State political processes as a means to address the abortion rights controversy.
From Crown Privilege to State Secrets1
Authors: Weaver William G. , Fisher Louis
Published: October 2023

The state secrets privilege is the most formidable evidentiary privilege available to the United States government. Available only to the executive branch, it is used to protect national security information from disclosure during litigation, and is habitually acquiesced to by courts. Once invoked, the privilege prevents covered material from being put into evidence that touches sensitive matters of national security. It is apparent that this privilege is subject to abuse by the executive branch to shield activities and personnel from judicial scrutiny and legal inquiries for reasons other than to protect national security. The privilege derives from British and Scottish doctrines of Crown Privilege that allow government to withhold evidence from legal proceedings to protect the public interest. The derivation of the state secrets privilege from the tradition of Crown Privilege has never been thoroughly explored. This article traces the influence of Crown Privilege in the development and evolution of the state secrets doctrine in the United States.
Analysis of Labor Market Transformation in the Context of Industry 4.0
Authors: Stryzhak Olena
Published: October 2023

The digitalization of the economy and society in the context of Industry 4.0 affects the labor market. New jobs are being created with new personnel requirements. At the same time, digitalization processes affect countries and sectors of the economy in different ways. The number of employed is declining in some sectors and increasing in others. The ratio of people employed in different industries also differs from country to country. As the digitalization of production relations intensifies, transformation processes in the labor market will increase. In the context of the actualization of digital changes in modern society, the aim of the article is to analyze the labor market under the digitalization of economic relations. The World Development Indicators (WDI) and Digital Intelligence Index (DII) were used to realize the purpose of the study. The study covers 89 countries for 2019. Correlation analysis, standardization, cluster analysis and analysis of variance were used as methods in the research. As a result of the study, the following conclusions were obtained. A strong relationship was found between Gross Domestic Product (GDP) and DII for the whole sample. The cluster analysis process found that the variables form three clusters with values of most indicators by group: at the high, the average and the low levels. Plots of mean and confidence intervals for the variables in each cluster were also plotted. Correlation coefficients were calculated for each cluster. It was found that each group has its own internal patterns.
A corpus-assisted discourse study on the construction of ‘obesity’ in Indonesian news media
Authors: Al Fajri Muchamad Sholakhuddin , Abdul Rahim Hajar , Rajandran Kumaran
Published: October 2023

Obesity is one of the health issues that is susceptible to discursive contestation and negotiation. The way it is portrayed in news media can affect public opinions and policymakers. This study aims to investigate the construction of ‘obesity’ in Indonesian online news media over a five-year period (2017-2021). The analysis was based on a corpus consisting of 1.418 news articles that mentioned the word ‘obesitas’ (obesity) by drawing upon corpus-assisted discourse study framework and legitimation theory. The findings showed that ‘obesity’ was predominantly constructed as a problem of personal responsibility, where individuals were viewed as solely responsible for minimising the risk of obesity and its associated health issues by losing or regulating their weight. This was frequently legitimised through expert authority by referring to medical experts’ interviews, or through impersonal authority by referring to scientific research. Meanwhile, the societal responsibility discourse which focused on the role of government and the food industry in creating conditions that led to obesity was very scarce. It is argued that this may reflect the presence of prevailing neoliberal ideology in Indonesian society. More balanced reporting, therefore, is recommended to lessen the stigmatisation of people with obesity and to recognise the variety of determinants of and solutions to obesity, reflecting its complexity more accurately.
Speech intelligibility of the diastratic varieties of Philippine English
Authors: Tak Jin-young , Zipagan Maribel , Kwak Eun Joo
Published: October 2023

The rise of English globalization has prompted speech production variations that reveal the cultural and social backgrounds of the different speakers. However, intelligibility issues of the different varieties have also become a concern. Thus, the present study attempted to assess the intelligibility of Philippine English (PE) diastratic varieties’ speech recordings produced by local Cebuano speakers. Further, it aimed to specifically evaluate the speakers’ production differences, rate the intelligibility of the language varieties, and determine the effect of language variety on the listener-evaluators in terms of intelligibility and distraction ratings. Using an exploratory sequential mixed method design, the speech participants in this study were carefully chosen through multistage sampling first by social class and then by phonological variations. The three final sample speakers out of the initial eighteen were finally categorized as acrolect, mesolect, and basilect. The evaluating groups included English language users from the USA, the Philippines, Korea, and Thailand, and each group represented a region in Kachru’s concentric circle of the World Englishes model. The results identified acrolect as the most intelligible variety followed by mesolect. Basilect, on the other hand, was considered very distracting to the evaluator groups, resulting in a significantly low intelligibility score. Thai evaluators gave the lowest intelligibility ratings, which may be attributed to two factors, L1 interference and unfamiliarity of L2 variation. Finally, future directions and implications in the classroom and industry are stated to create a sense of cultural awareness and to promote a deeper intercultural understanding that comes with international intelligibility.

Congenital hypothyroidism diagnosed on the sixth day of life: a case report.
Authors: Ertel Douglas , Ferrini Filho Aldo , Sales Ludmila , Oliveira Dayana , Zaconeta Carlos
Published: October 2023

Introduction - Congenital hypothyroidism results from insufficient secretion of thyroid hormones, which are related to the maturation of the central nervous system, being the main cause of preventable intellectual disability in childhood. The diagnosis can be suspected from the neonatal screening test, revealing its importance, since most cases are asymptomatic or oligosymptomatic at birth with nonspecific manifestations, as well as the classic manifestations become evident only later, causing neurological damage. Objective - describe a clinical case of a patient diagnosed with congenital hypothyroidism on the sixth day of life, screened through the neonatal screening test, with subsequent laboratory confirmation, highlighting points of diagnosis, treatment and clinical follow-up, avoiding the progression of late diagnosis. Case report - male patient, born through normal delivery without complications, who developed asymptomatic hypoglycemia at the first hours of life, treatment resistant. The patient presented alterations compatible with congenital hypothyroidism in the neonatal screening test, with subsequent confirmation through laboratory tests. Thyroglobulin replacement was started on the seventh day of life, with progressive improvement in hypoglycemia and favorable clinical evolution throughout the first months of life. Conclusion - Congenital hypothyroidism is the main cause of preventable intellectual disability in childhood, it must be diagnosed as early as possible, demonstrating the importance of neonatal screening tools. After the institution of appropriate treatment and clinical follow-up, the evolution is favorable, avoiding the drastic progression of late diagnosis.

Authors: Florêncio Livia , Lange Eloana , Pereira Elizandra , Silva Mariana , Haddad Gabriela
Published: October 2023

Objectives: Acrodermatitis Enteropathica (AE) is a rare disease that can be transmitted by autosomal recessive inheritance, it can be related to parenteral nutrition without zinc, or it can be secondary to malabsorptive syndromes. Clinically, it is characterized by the triad of acral and periorificial dermatitis, alopecia and diarrhea, accompanied by growth restriction. The condition can be fatal if left untreated. Methods: We describe the case of a child with AE and Crohns Disease (CD), with AE being a known complication, secondary to malabsorption caused by CD. Results: Treatment for CD was started with systemic steroids, Azathioprine and Mesalazine, and local care with the diaper area. Oral zinc replacement was also started. The child showed significant clinical and dermatological improvement within a few weeks. Conclusions: The diagnosis of AE is made with serum zinc levels lower than 70 ug/dL. Treatment involves zinc supplementation, at a dose ranging from 1 to 3 mg/kg/day. In the case described, the zinc value was 65 ug/dL. In this case, we started replacement with 2mg/kg/day, with rapid clinical improvement. Zinc deficiency AE is a well-known complication of CD, secondary to malabsorption. In the case described, the cutaneous condition came after the intestinal condition, with the deficiency in the absorption of zinc being secondary to Crohns Disease, leading to a condition with extensive lesions, but with a quick response to the treatment and with an important improvement of the condition.

Published: October 2023

Objective: To report the case of a newborn with a pre-pyloric mucosal diaphragm with repercussions on weight gain and food acceptance. This is a rare congenital gastrointestinal malformation and corresponds to approximately 1% of all etiologies of gastrointestinal obstruction in newborns. Description: Female NB, started post-feeding vomiting at 4 hours of life. Multiple attempts of oral feeding reintroduction were performed, episodes of post-feeding vomiting and inadequate weight gain were maintained. Imaging exams did not show intestinal obstruction, an upper digestive endoscopy (UDE) was performed on the 19th day of life, which identified and corrected a pre-pyloric mucous diaphragm with transposition of the membrane by the device. Formula was reintroduced, with a gradual increase in supply and satisfactory weight gain. He was discharged at 24 days of life, with total acceptance of the diet and complete remission of the condition. Comments: This study shows that it is important to consider the performance of UDE in cases of prolonged neonatal vomiting, after excluding more prevalent causes, such as APLV and GERD, as it is capable of diagnosing and treating some causes of obstruction of the gastrointestinal tract, such as the diaphragm prepyloric mucosa.

Published: October 2023

OBJECTIVE: To analyze the infant mortality rate due to intrauterine hypoxia and perinatal asphyxia in the State of Pará from 1996 to 2019. METHODS: A retrospective, descriptive and quantitative study was conducted using data from the DATASUS database from the Ministry of Health. RESULTS: The annual infant mortality rate due to intrauterine hypoxia and birth asphyxia in the state of Pará has been decreasing since 1996 to 2019, albeit at a slower rate compared to the national average. The state of Pará has seen a 41% reduction in infant mortality between 1996 and 2019, a smaller decrease compared to the national and North Region indices which were respectively 64% and 72%. Pará was the state in the North region that least managed to reduce infant mortality related to the condition, becoming the holder of the highest infant mortality rate in the North region in 2019.
Factors medicated that influence the production of breast milk
Authors: Vasconcellos Patricia , Colvero Mauricio , Fiori Humberto
Published: October 2023

Introduction: Several factors may affect the production of breast milk - among them, the difficulty in breastfeeding per se, the reduction of oxytocin due to stress, and the use of medication. In this study, a systematic review of the subject has been made through the use of the following databases: PubMed, Scielo, and LILACS. Objective: To evaluate the factors medicated that influence breas tmilk production. Discussion: Medications such as galactagogues and lactation inhibitors interfere in the process - either increasing or decreasing the volume of milk produced by the mothers. Conclusão: On the other hand, medications like metoclopramide, sulpiride, and domperidone are galactagogues, that is, they increase milk production. Among the medications that may inhibit lactation, pseudoephedrine stands out. However, further studies are necessary to evaluate the actual safety of mothers use of medication while breastfeeding.

Translation features of BBC media article headlines (evidence from English and Russian equivalents)
Authors: Filyasova Yu.A.
Published: October 2023

The aim of this paper is the analysis of the translation features, typical of BBC article headlines. The material included 107 news headlines selected randomly, which had their Russian equivalents. A semantic and comparative analysis served as the research method. The close attention to media texts in the era of digital technology proliferation explains the relevance of the study. The findings show that translation equivalents convey both the communicative and pragmatic potential of the original headlines. For this purpose, a complex of semantic transformations is used for maintaining the adequate meaning of original news in the target language, considering background knowledge of the target audience. The theoretical value lies in the fact that media headlines constitute an individual sub-genre which requires special research. The results can be used in the practice of teaching translation techniques to students specializing in linguistics and translation studies.

Variability in journalistic discourse in the German language
Authors: Shubina E. L.
Published: October 2023

This work is devoted to the problem of syntactic organization of nominal groups with the first component, denoting the names of groups of animals, namely Rudel (flock), Schwarm (swarm), Herde (herd). Interest in phrases of this type is due to the increased frequency of use in journalism in Germany, as well as the peculiarities of syntactic construction. The corpus of journalistic texts made it possible to see the quantitative distribution of models with the help of which phrases such as ein Rudel Wölfe (pack of wolves) were formed, and also demonstrated a partial discrepancy between the use and regulatory requirements. Substantive groups with an uncommon second component were designed according to the models: eine Herde + Subst. Singular (Plural) (eine Herde Schafe, Vieh); eine Herde + Subst. Attr. Genitiv (einem Rudel Gleichgesinnter); eine Herde + von+ Subst. Attr. Dativ (einer kleinen Herde von Gläubigen); einer Herde (Dativ)+Subst. Plural (Dativ) (einem Rudel Hunden). Substantive groups in which there is an adjective or participle before the second component were constructed according to the models: eine Herde + Attr. + Subst. Genitiv (ein Rudel friesischer Hunde); eine Herde + von (mit, an, aus) + (Numeralien)+ Attr.+ Subst. Plural (Dativ) (Herden von kamelartigen Alpakas); eine Herde+Attr.stark+Subst.=Herde (ein Rudel braune Krankenschwestern). Corpus data showed that a significant proportion of phrases do not have case marking, that is, the case of the second component is not determined, just as the type of syntactic connection is not determined. The proportion of ambivalent forms was 18% for groups with Herde, 28% for combinations with the first component Schwarm, and 41% for groups with Rudel. In contexts with case marking, models with genital control and prepositional control compete. It turned out that models with the coordination of eine Herde + Attr.stark + Subst.=Herde and einer Herde (Dativ) + Subst. Plural (Dativ) are represented by single examples, although authoritative normative grammarians consider these models to be valid for organizing these noun groups. Another important difference from the recommendations of authoritative grammars is that prepositional control is represented by a more diverse list of prepositions (von, mit, an, aus). It can be assumed that prepositions help a native speaker to overcome uncertainty in the choice of case, since the realized use of a preposition imposes strict restrictions on the case of a noun.

Authors:   University of Piraeus, Faculty of Industrial Management and Technology, Piraeus Greece, Zampeta Vicky , Chondrokoukis Gregory ,   University of Piraeus, Faculty of Industrial Management and Technology, Piraeus Greece
Published: October 2023

Purpose: The article aims to highlight the concept of risk management in maritime transportation accidents in the specialized literature on the Web of Sciences database through existing materials. Design/methodology/ approach: The keyword study identifies several keywords as they have been set in this study and as they appear in the Web of Science database. Using VOSviewer our main concern is to identify and highlight the most essential and questioned words associated with the “maritime accidents” and “other issues related with maritime accidents” concept. We extracted 456 articles, underlined 259 keywords with the similar meaning to the keywords we have selected in the previous stage. Findings: We found that the maritime transportation accidents (MTA) topic has limited expansion in the literature. The gaps are considerably big leaving space for further research. The analysis of the keywords proves an interconnection between the MTA, the risk models, safety, management organization and more. Research limitations/implementations: Although there has been an increased interest in this field especially among countries with the shipping sector highly developed (maritime universities in China, London Poland, etc.), we have noticed that the related studies are still at the beginning, especially if we consider the accounting side of this subject. Originality value: The present article can only be the beginning of a set of studies in MTA, given that the issue has an increasing interest in academia. For future research, we can consider using a larger sample, more keywords, and additional databases.
The Effect of the Movement in 52-Week High on Momentum Profit: The Evidence from Taiwan
Authors:   School of Economics and Management, Xi'an University of Technology, China, Liao Li-Chuan , Chang Tzu-Pu , Wang Ping-Huang ,   Department of Finance, National Yunlin University of Science and Technology, Taiwan,   Department of Finance, National Yunlin University of Science and Technology, Taiwan
Published: October 2023

Purpose: This paper aims to examine the impact of price movements in 52-week highs on a 52-week high momentum strategy. This study refers to the upward or downward movement in 52- week highs as an updating effect and determines how this effect influences the profitability of the original 52-week high momentum strategy. Design/methodology/approach: This paper decomposes the ratio of stock price to 52-week high into denoted two components: price change and updating components. We construct two momentum strategies, each focusing on adjusting either the price change or the updating component. Additionally, we employ a portfolio approach and Fama-MacBeth regression analysis to investigate the profitability of each proposed momentum strategy. Findings: The empirical results reveal that removing the price change component (updating component) from the original 52-week high measure can increases (decreases) the momentum profit, implying that the updating component dominates the price change component. Moreover, our analysis shows that when a high ratio of stock price to 52-week high is driven by a downward updating event, the subsequent positive momentum for a winner portfolio is more substantial. Research limitations/implications: This paper investigates the influence of 52-week highs movement on momentum strategies, utilizing data from Taiwan stock market. The findings reveal that accounting for the updating effect of 52-week highs can enhance the profitability of the original momentum strategy. However, it is important to note that this conclusion is currently limited to relatively inefficient stock markets. The impact on relatively efficient markets remains an area that requires further research for a comprehensive understanding. Originality/value: The finance literature widely acknowledges the 52-week high price as a reference point that can impact investors' trading psychology. Numerous empirical studies have confirmed the profitability of the 52-week high momentum investing strategy. However, these studies have not thoroughly explored the implications and effects of price movements within the scope of a 52-week high momentum strategy. Taking behavioral perspectives into account, this paper considers that the updating of 52-week high prices can influence investors' attention and subsequently impact the profitability of the momentum strategy.

Space Launch System Unsteady Forces Developed from Unsteady-Pressure-Sensitive-Paint–Based Corcos Model Parameters
Authors: Soranna Francesco , Heaney Patrick S. , Sekula Martin K. , Piatak David J. , Ramey James M.
Published: October 2023

During atmospheric ascent, launch vehicles (LVs) experience large dynamic loads at transonic conditions where aerodynamic buffet is most critical. To estimate buffet loads, coupled loads analyses typically utilize suitable forcing functions, called buffet forcing functions (BFFs). One of the key buffet environment contributors is the turbulent boundary layer (TBL) acting on the LV outer skin. The cross-spectral density function of TBL-induced fluctuating pressures can be estimated using the widely accepted Corcos model. In the context of transonic buffet, the performance of this model is not well established, partly because of lack of data. To fill this gap, NASA recently acquired extremely high-spatial-density data for the Space Launch System vehicle using the unsteady-pressure-sensitive-paint (uPSP) optical measurement technique. A methodology is developed for extraction of the Corcos model parameters using these unique data, with a focus on the LV design application. The model hypotheses are verified, and the model parameters are empirically tuned. For selected panels on the vehicle, force coherence factors are derived based on the Corcos model, and the associated panel BFFs are compared to uPSP data. It is shown that the modeled BFFs are in agreement with direct integration of uPSP data, except for regions where pressure fluctuations are spatially nonuniform. In those regions, the Corcos-based BFFs exhibit inherent limitations of BFF estimation methods that rely on discrete pressure measurements. Lastly, extending the present implementation of the Corcos model to frequencies impacted by vortex-shedding phenomena can result in underconservative BFF estimates at the subharmonic of the vortex shedding.

The Fire Dynamics Simulator (FDS) model was utilized in this study to replicate a full-scale aircraft postcrash experiment conducted within the C-133 test facility by the Federal Aviation Administration. FDS is a computational fire field model that incorporates submodels for soot formation, pyrolysis, and thermal radiation transport. It solves three-dimensional time-dependent Navier–Stokes equations and is grounded in the large-eddy simulation approach and the eddy dissipation concept, serving as turbulence and combustion models. The obtained results, including the heat release rate and temperature, were validated against experimental data and compared with earlier prediction studies employing different turbulence and combustion models. The results from this simulation closely align with the experiment’s findings. The impact of fire-blocking layers and carry-on baggage on interior material was examined. Moreover, two boundary conditions were imposed on the fuselage structure: 1) the adiabatic wall, and 2) heat loss within the wall. Both the fire-blocking layers and the adiabatic boundary condition played a significant role in the flashover occurrence. The large-eddy simulation and eddy dissipation concept approaches have demonstrated a reliable ability to predict flashover and general fire properties to a considerable extent.

One of the main tasks of the development of the oil refining industry at the moment is: involvement in the processing of increasingly heavy oils with a high content of high-boiling fractions and residues, sulfur, resins and metals; increasing the depth of oil refining; tightening environmental requirements for fuel quality; meeting the growing demand for high-quality motor fuels. At the same time, the climatic conditions of the Russian Federation cause a great need for high-quality low-pour-ing diesel fuels, which is currently provided by less than half. Taking into account the special requirements in the northern regions of Russia for the lowtemperature characteristics of motor fuels, the task of producing low-solidification diesel fuels that meet modern and future environmental requirements is especially relevant. This article describes the current industrial technologies for the production of low pour point diesel fuels, their advantages and disadvantages, as well as their prevalence in the world.

The possibility of using both gas-phase (CO2) and liquid-phase (HNO3, H2O2) modification of cellular carbon foam with the study of changes in the content of oxygen-containing groups on its surface is shown. It has been established that when the cellular carbon foam is activated in a CO2 at a temperature of 350°C, there is no loss of mass of the initial sample, and an increase in the activation time from 1 to 3 hours leads to an increase in the number of functional groups by 11 rel.%. Liquid-phase oxidation allowed us to establish that an increase in the concentration of the oxidant, as well as the temperature and duration of the process leads to an increase in the number of functional groups on the surface.

A persistent pupillary membrane (PPM) is a congenital eye condition characterized by the presence of remnants of tissue in the eye that normally regresses during fetal development. A 37-year-old male patient complained of bilateral blurred vision for distance that had been present from childhood and was accompanied by glare and photophobia. On examination, uncorrected distance visual acuity was 20/30 in the right eye and 20/40 in the left eye, and there was no improvement with pinhole. The slit-lamp examination showed PPM with covering pupil partially in both eyes. The management of PPM depends on the severity of the condition and its impact on vision and ocular health.
