THE STATUS OF THE DOUBLE EPIGRAPH TO THE POEM “YOUR WAY”
Authors: Prozorova Natalya
Published: January 2023

Epigraphs to the works of O. F. Bergholz have not been studied specifically until now. The two-part epigraph to the poem “Your Way” (1945) was not approved for publication during the poet’s lifetime and was first published in 1989. In the initial position of the epigraph is a biblical quote from Psalm 136, which begins with the words “If I forget you, Jerusalem...”; in the second — the line “Die and become!” from the poem “Blissful longing” by Goethe. The biblical quote was a precedent text and a core attitude for the poetess long before the poem “Your Way” was written. The besieged Leningrad was interpreted as the “Leningrad Jordan.” The image of the besieged Jordan (later excluded by editors and/or censors) is the most important sign indicating the semantic connection of the biblical epigraph with the text of the poem. Bergholz built a single spiritual space and set the “Jerusalem” — “Leningrad Jordan” vector; familiarization with the “burning” waters of the river meant an assimilation of the bitter blockade experience. At the same time, Bergholz built a vertical context: the sacred waters of the Jordan symbolized the rebirth to a new life (baptism), the self-discovery of man. The image of the Leningrad font correlated with the epigraph from Goethe, in which the theme of initiation is explicitly stated. The author of the article suggests that epigraph “Die and become!” was intended by Bergholz for the poem “February Diary” (1942), but was excluded from the text by A. P. Grishkevich, head of the press sector of the Leningrad City Committee of the CPSU(b). Goethe’s dictum has become the motto of the poetess since the time of the “Averbach case” repressions (1937). The double epigraph gave a semantic and philosophical perspective to the poem “Your Way.” The editorial intrusion (the exclusion of epigraphs and lines about the “Leningrad Jordan”) destroyed the connection of the title with the epigraph and the text, and impoverished the perception of the poem by contemporary readers. The two-part epigraph correlates with Bergholz’s entire blockade narrative, emphasizing the themes of memory and initiation as the spiritual formation of a Leningrad blockade runner.
RUSSIAN HANDWRITTEN WORKS ON THE “IMMUTABILITY OF THE DESTINIES OF GOD” (THE PLOT OF “MARCO THE RICH”)
Authors: Pigin Alexander
Published: January 2023

The article is devoted to handwritten works of the 17th–19th centuries, in which the global plot known as “Marko the Rich” in Russian materials, is used: a rich man receives a prophecy that his son-in-law and heir will be the son of poor parents; he tries to ruin the boy, but the prediction comes true. The plot was known both in Europe and in the East, it penetrated into Russian literature in the Middle Ages. The focus is on four works: “Example” (Priklad) about the Caesar Conrad and the knight’s son from the “Roman Acts” (Gesta Romanorum), “The Tale of a Rich Merchant,” a short novel without a title from the manuscript codex of the Library of the Russian Academy of Sciences (Arkhangelsk collection, S. No. 138), “The Short Novel About the Rich and the Poor, and How God’s Destinies are Immutable” from the manuscripts of the 19th-century Pechora Old Believer scribe I. S. Myandin. The last two works are being examined for the first time. The article examines the composition and plot of the literary works, as a comparative material, folklore tales about Marko the Rich are used. Literary works differ in origin (“Example” is a translated work, the rest are original), in the time of creation, and in plot development. At the same time, they are all religious works that affirm the idea of the dependence of human fate on God’s providence. Genetic connections between the works are not clearly traced, and the appearance of certain motifs in the texts is explained by the influence of folklore tales.
Incidence of Acute Kidney Injury in Hospitalized Children: A Meta-analysis
Authors: Meena Jitendra , Mathew Georgie , Kumar Jogender , Chanchlani Rahul
Published: January 2023

BACKGROUND AND OBJECTIVES

There is limited literature on the incidence of acute kidney injury (AKI) and associated mortality in hospitalized children. To systematically assess the worldwide incidence of AKI in hospitalized children to inform policymakers regarding appropriate health resource allocation.

METHODS

Three different databases were searched (PubMed, Embase, Web of Sciences) from March 2012 to January 2022 without language or geographical restrictions. We included cohort and cross-sectional studies that reported AKI incidence in hospitalized children. Eligible studies had at least 100 participants and used the standard Kidney Disease Improving Global Outcomes criteria to define AKI. Two authors extracted data on the study and patients’ characteristics and outcomes (incidence and AKI-associated mortality) and performed the risk of bias assessment. We used a random-effects meta-analysis to generate pooled estimates.

RESULTS

We included 94 studies (202 694 participants) from 26 countries. The incidence of any AKI was 26% (95% confidence interval: 22–29), and that of moderate-severe AKI was 14% (11–16). The incidence of AKI was similar in high-income 27% (23–32), low-middle-income 25% (13–38), and low-income 24% (12–39) countries. Overall, AKI-associated mortality was observed in 11% (9–13) of the pediatric population. AKI-associated mortality rate was highest at 18% (11–25) and 22% (9–38) in low-income and low-middle-income countries, respectively.

CONCLUSIONS

AKI was observed in one-quarter of the hospitalized children and is associated with increased mortality risk. Low-income and low-middle-income countries had observed higher mortality rates compared with high-income countries despite a similar AKI burden.
КОНЦЕПТ ІСТИНИ У ДАВНЬОГРЕЦЬКІЙ ФІЛОСОФІЇ: ΑΛΗΘΕΙΑ ЯК СЕМАНТИЧНИЙ КЛАСТЕР
Authors: Pavlenko Igor
Published: January 2023

Розглядається давньогрецьке поняття істини щодо мови та мовних контекстів. Істина представляється як металінгвістичний контекст, який породжує численні смислові об’єкти, що функціонують як семантичні поля. Аналізується уявлення про істину як семантичну структуру у зв’язку з особливостями використання поняття ἀλήθεια в античній філософії, пропонується програма дослідження поняття істини у давньогрецькій мові. Дослідження є першим наближенням до реконструкції алетіології давньогрецької філософії класичного періоду. Для цього передбачається розглянути поняття ἀλήθεια як семантичну домінанту або наддомінанту, за якою слідують її приватні локалізації. Необхідною складовою такого дослідження є також систематизація та класифікація контекстів, у яких використовується дане поняття. Мова йде про контексти істини, або про саму істину як суму контекстів, у яких протікає життя людини. Тут істина може розглядатися, в одному випадку, як конгломерат, хаотичне поєднання розрізнених елементів або ж як система смислових зв’язків, що охоплюють різні області дискурсу, де природна мова виступає в якості першоджерела, матеріалу, мега-нарративу, вихідного для будь-якого можливого розгляду істини.
Indirect self-destructiveness in women with schizophrenia
Authors:   Pracownia Psychologii Klinicznej i Psychoterapii, Katedra Psychologii, Uniwersytet Jana Kochanowskiego w Kielcach, Kielce, Polska, Tsirigotis Konstantinos
Published: January 2023

Background: Many authors emphasise the influence of gender differences on mental health and the course and experience of mental illness, and/or postulate a gendered perspective in mental health research. Research holistically considering indirect selfdestructiveness in women with schizophrenia is hard to find in the international literature; studies have been performed on the sole basis of some discrete manifestations of indirect self-destructiveness. Aim: The aim of this study was to explore the indirect self-destructiveness syndrome and its categories in women with schizophrenia. Method: A group of 125 women with paranoid schizophrenia, aged 27–57, were examined by using the Polish version of the Chronic Self-Destructiveness Scale (CS-DS); for comparison, a group of 175 men with schizophrenia and a sociodemographically well-matched group of 125 healthy women were examined. Results: The intensity of indirect self-destructiveness and most of its categories were found to be greater in the group of women with schizophrenia compared to men with schizophrenia (transgression, poor health maintenance, personal and social neglects) and healthy women (transgression, personal and social neglects, lack of planfulness, helplessness). Nevertheless, women with schizophrenia displayed signs of better psychosocial adjustment than schizophrenic men. Conclusions: Comprehensive therapeutic, i.e. psychiatric, psychological and social, interventions should serve to enhance the “self ” defence and self-care functions, and improve the evaluation of adequacy and efficiency in women with schizophrenia. Working with such patients towards increasing their life satisfaction, although life did not spare them suffering, seems to be equally important in (psycho) therapy. The mobilisation and orientation of their actions towards those in favour of their development and health appear as crucial.

Authors: Ajay Babu M. , Shanmukh Kumar J.V. , Naresh N. , Mankumare Sharad D.
Published: January 2023

A rapid, stability indicating reverse phase liquid chromatographic method was developed for the determination of purity of Felodipine in active pharmaceutical substance form in the presence of its impurity and its degradation products. To develop the method which is also compatible to liquid chromatographic mass spectroscopic technique. The developed method is also used to determine the assay of Felodipine in bulk drug form. The drug is subjected to various stress conditions like acidic, basic, oxidation, UV light and thermal conditions. Considerable degradation was observed during base hydrolysis. Two degradation products were identified. The Waters Acquity UPLC BEH C18, 2.1 × 100 mm, 1.7 µm Column was used to achieve chromatographic separation. The gradient conditions, diluent and injection volume were optimized to achieve the acceptable resolution between impurities and its degradation products from Felodipine and to get good peak shapes. The masses were determined for main compound and its identified degradation products. Further, the characterization studies for main compound and its degradation products were performed using LCMSMS Q-TOF.
Microdosing psychedelics – Does it have an impact on emodiversity?
Authors: Pop Ioana , Dinkelacker Jannis
Published: January 2023

Background and aims

Previous research has proposed that microdosing, i.e., the repeated use of sub-threshold doses of serotonergic hallucinogens, has an impact on mood by increasing emotional awareness. We propose that increased emotional awareness could translate into higher emodiversity, a balanced experience of emotions in which emotions are experienced with more similarity in intensity and duration. We examine the effect of microdosing, the day after, as well as the cumulative effect of microdosing on overall, positive and negative emodiversity.

Methods

We use data collected over a period of 28 days sampled between February to June 2020 from 18 users that already had an active practice of microdosing at the start of the data collection. We assessed emotional states using ESM methods, i.e., signal-contingent sampling with triggers sent 5 times a day. The working dataset has a number of 224 observations days. We used mixed effects models to test our hypotheses.

Results

When taking into account the level of average affect, we found that during microdosing days positive and overall emodiversity were significantly lower. No evidence was found for a mediating role of the level of average affect. Higher cumulative instances of microdosing were not related to any of the emodiversity indexes. Participants experienced more “awe, wonder, or amazement”, “ashamed, humiliated, or disgraced” as well as less “joyful, glad, or happy” emotions during microdosing days.

Conclusion

A microdosing practice may increase the centrality of certain emotions on microdosing days, resulting in a decrease in emotional diversity.
Preparation of polyvinyl acetate composite as a new backing material for the manufacture of ultrasonic transducers
Authors: Barakat Mirham A. Y. , El-Wakil A. A.
Published: January 2023

Polyvinyl acetate (PVAc) composites were loaded with varying amounts of nano-metal alloy (Ag–Sn–Cu–Pt) and stearic acid. They are used as backing materials for ultrasonic transducers to prevent back-echoes from reverberating into the piezoelectric element and to reduce noisy echoes. The novelty of this work is the usage of these newly prepared PVAc/alloy composites as backing material in ultrasonic transducers with a polyvinylidene fluoride (PVDF) active element. The X-ray diffraction (XRD) technique was used to examine the structure of the composites. The ultrasonic technique investigated the ultrasonic attenuation coefficient, the acoustic impedance, the mechanical properties, and other parameters. The transducers with the new backing composites gained high sensitivity, broadband, short ringing, and so on. These characteristics were improved by increasing the nano-metal alloy content in the backing composites. The study also proved the efficiency of the PVAc/alloy composite as new backing material in ultrasonic transducers.

Graphical abstract

Sketch of fabricated ultrasonic transducers with backing materials from PVAc/alloy composites (B1, B2, B3, B4, B5, and B6) and their important features (BW is transducers’ band width and S is transducers’ sensitivity).
The Five Principles of Middle Way Philosophy: Living Experientially in a World of Uncertainty
Authors: Ellis Robert M.
Published: January 2023

This second book in the ‘Middle Way Philosophy’ series develops five general principles that are distinctive to the universal Middle Way as a practical response to absolutization. These begin with the consistent acknowledgement of human uncertainty (scepticism), and follow through with openness to alternative possibilities (provisionality), the importance of judging things as a matter of degree (incrementality), the clear rejection of polarised absolute claims (agnosticism) and the cultivation of cognitive and emotional states that will help us resolve conflict (integration). These are discussed not only in theory, but with links to the wide range of established human practices that can help us to follow them. Like all of Robert M. Ellis’s work, this book is highly inter-disciplinary, drawing on philosophical argument, psychological models and values that prioritize practical application.
W stronę teologii nauki – na kanwie myśli ks. prof. Michała Hellera
Authors: Maziarka Tomasz
Published: January 2023

Artykuł podejmuje zagadnienie relacji nauki do teologii, w oparciu o myśl ks. prof. Michała Hellera, i zmierza ku takiemu ujęciu obydwu dyscyplin, w którym nauka staje się przedmiotem zainteresowania teologii. Punktem wyjścia jest refleksja nad fenomenem racjonalności świata. Racjonalność stanowiąca warunek uprawiania nauk przyrodniczych domaga się usprawiedliwienia. Teologiczną prawdą, która może przyjść z pomocą, jest wiara w istnienie Logosu; Boska Mądrość, przenikając wszystko, nie tylko stanowi fundament struktury świata fizycznego, ale określa również istnienie świata wartości i sensu. Skoro Bóg stanowi filozoficzne a priori każdej z nauk, nauki przyrodnicze mogą prowadzić dialog z teologią, a nawet – co postuluje ks. Michał Heller – możliwe jest stworzenie programu teologii nauki. Celem takiego przedsięwzięcia jest wzbogacenie spojrzenia na naukę przez uwzględnienie tych aspektów, które są widoczne jedynie przy użyciu metody teologicznej.
Septuaginta – pragnienie poznania Biblii
Authors: Łabuda Piotr
Published: January 2023

The Septuagint which contains texts not presented in the Hebrew Bible is at the same time its formal and ancient translation. It is not just an interpretation either. It is not meant only for the ancient societies, but should be treated as a valuable Text by contemporary people as well. The Book was created as a result of the need to learn the Bible. The Septuagint made the texts of the Hebrew Bible accessible for both the Jews and the Greeks. The Greek Bible became useful for literary, legal and synagogical purposes. Undeniably it helped people get closer to the mystery of Jesus Christ.
„Nienawiści karmi nas pucharem” . Rozpad Jugosławii w latach 90. XX w. w imaginacjach geopolitycznych polskiej muzyki popularnej
Authors:   Uniwersytet Zielonogórski, Macała Jarosław
Published: January 2023

The article focuses on the interference of Polish popular music and geopolitics after 1989. Songs selected from various trends of the Polish popular music made the source material of the text. The basic study method involved critical discourse analysis of the lyrics. The hierarchical East-West axis, which was also applied to the Balkans and Yugoslavia, was fundamental to Polish geopolitical perceptions. The musical image of Yugoslavia from the 1990s seemed repulsive with its strangeness and “Easternness”, which were proven by bloody wars and crimes in Bosnia and Kosovo. In the name of superiority of the Western world and geopolitical interests, musicians appealed to Western countries for military interventions in the former Yugoslavia. At the same time, they strengthened the direction towards the occidentalization of Poland as a condition for its security and development at the price of submission to the dominance of the West in the world and in Europe.
Nacjonalizm integralny jako sposób budowania narodu za pośrednictwem autorytetu monarchy. Analiza myśli Charles’a Marie Maurrasa w odniesieniu do współczesnych monarchii europejskich
Authors:   Uniwersytet Śląski w Katowicach, Bieniek Barbara
Published: January 2023

The aim of the article is to analyze Charles Maurras’ concept of integral nationalism, in which he assumed the restoration of the limited monarchy to be the only appropriate governance model which enables a nation to develop. The first part outlines Ch. Maurras’ perception of integral nationalism and the role of monarchy in relation to the nation. The latter part is an attempt to use the French version of nationalism in modern European monarchies and find a set of characteristics that should represent the new royal power. The results of the research show that Maurras’ new version of nationalism was not as utopian as it was claimed by his critics and has applications in modern European monarchies.

The main objective of the paper is to analyse the impact of the COVID-19 pandemic on the situation of Polish women whose common features are uncertain life circumstances. In March and April of this year, we held a qualitative study on this subject (Focus Group Interview). The choice of this research tool allowed for collecting testimonials that resulted in better understanding of problems and attitudes of women who due to their specific life circumstances were likely to endure more severely the consequences of the pandemic. Our analysis of presented input also leads to a conclusion about the dysfunctional nature of social policy.
Korupcja jako zaburzenie międzyludzkiej komunikacji w świetle nauczania papieża Franciszka
Authors:   Uniwersytet Papieski Jana Pawła II w Krakowie, Nęcek Robert
Published: January 2023

The Pope, as the head of the Church and the head of the State, is obliged to undertake appropriate forms of criticism and counteract the improper functioning of the institutions of the Church and the State. The point is that the task of politics and the state is to strive for the common good, and one of its functions is to integrate society. In both cases, there must be undisturbed communication, and this is precisely what corruption is disturbing. In the teachings of Pope Francis, a corruption disorders a communication in a way that it creates crisis of trust and arouses suspicion among the people. It ignores the truth which is a guarantee of clarity and understanding. The corruption, that grows and continues to evolve, is transmissible and it justifies itself by creating its own doctrine. Corruption is a rejection of solidarity. Pope Francis says about halitosis and sclerosis of a spiritual heart. He says about a sin and a corruption. Corruption evokes a social paralysis, which unfortunately is paid for by the poorest. Francis claims that it is not enough to sentence corrupted people, but it is important to pray for their conversion.
Mobile eye tracking applied as a tool for customer experience research in a crowded train station
Authors: Schneider Andrea , Vollenwyder Beat , Krueger Eva , Miller David B. , Thurau Jasmin , Elfering Achim
Published: January 2023

Train stations have increasingly become crowded, necessitating stringent requirements in the design of stations and commuter navigation through these stations. In this study, we explored the use of mobile eye tracking in combination with observation and a survey to gain knowledge on customer experience in a crowded train station. We investigated the utilization of mobile eye tracking in ascertaining customers’ perception of the train station environment and analyzed the effect of a signalization prototype (visual pedestrian flow cues), which was intended for regulating pedestrian flow in a crowded underground passage. Gaze behavior, estimated crowd density, and comfort levels (an individual’s comfort level in a certain situation), were measured before and after the implementation of the prototype. The results revealed that the prototype was visible in conditions of low crowd density. However, in conditions of high crowd density, the prototype was less visible, and the path choice was influenced by other commuters. Hence, herd behavior appeared to have a stronger effect than the implemented signalization prototype in conditions of high crowd density. Thus, mobile eye tracking in combination with observation and the survey successfully aided in understanding customers’ perception of the train station environment on a qualitative level and supported the evaluation of the signalization prototype the crowded underground passage. However, the analysis process was laborious, which could be an obstacle for its practical use in gaining customer insights.
Discriminating Borders: Nationality, Racial Ordering, and the Right to Exclude
Authors: Menge Torsten
Published: January 2023

State borders allocate access to basic goods, opportunities, rights, and protections along lines of nationality, race, and gender. However, the discriminatory effects of state borders rarely appear as an issue in the self-understanding of liberal-democratic societies and their political theorizing. In this paper, I explore how the category of nationality has been and continues to be used to exclude people who have been negatively racialized by European colonialism. I draw on a number of studies that reconstruct the colonial history of states' claims to authority over people's movements and over the composition of their populations. The idea of territorial nationalities allowed nation-states, in particular those emerging from the settler colonies and metropoles of European empires, to continue practices of racial ordering without using explicit racial categories. With the help of these studies, I criticize liberal nationalists such as David Miller for appealing to the value of national identities to support a right of states to exclude would-be immigrants. I suggest that using genealogical and phenomenological methods allows us to undermine the default authority that is often accorded to the category of nationality.
Способы повышения эффективности территориальных систем энергоснабжения

Published: January 2023

Исследованы системы энергоснабжения, в составе которых имеются источники, использующие различные технологии совместного производства тепловой и электрической энергии. В крупных городах России высока доля поставок тепловой энергии от теплоэлектроцентралей, но в больших и средних – доминирует ее производство на котельных. Соотношение объемов производимой совместным способом тепловой и электрической энергии с общим потреблением позволяет судить о состоянии и эффективности территориальных систем энергоснабжения. Практически повсеместное отсутствие коммунальных мини-ТЭЦ и ограничение на поставку электроэнергии, произведенной крупными ТЭЦ в теплофикационном режиме на розничный рынок, ведут к снижению эффективности городских и региональных систем энергоснабжения. Основное число потребителей, кроме предприятий, использующих собственные когенерационные источники, ограничены в доступе к недорогой тепловой и электрической энергии. Актуально увеличение доли когенерационного производства энергии. Необходим показатель, характеризующий уровень интеграции источников совместного производства тепловой и электрической энергии в системах энергоснабжения. Основной потенциал создания интегрированных систем энергоснабжения сосредоточен в больших и средних городах, где производство тепловой энергии осуществляется на котельных. Их преобразование в мини-ТЭЦ соответствует стратегии энергетического перехода к распределенной энергетике, но требует внесения изменений в процесс управления развитием муниципальной и региональной энергетики. Наличие благоприятных условий для частных инвестиций в развитие интегрированных систем энергоснабжения соответствует целям устойчивого социально-экономического развития территорий.

The UN Paris Climate Agreement requires unprecedented efforts to prevent global warming above 1,5-2°C. Despite geopolitical, economic and other disruptions, cooperation in climate sphere is one of the key directions of international interaction among the world leading economies. Many countries adopted decarbonization strategies and carbon neutrality targets by 2050-2070. The economic analysis the decarbonization scenarios showed that zero-carbon technologies in energy, industries and other sectors can play a crucial role in reduction of carbon emissions worldwide. Achievement of Paris Agreement goals can be more efficient if the mechanisms of international climate cooperation, carbon pricing and regulation would be broadly applied.

Authors: Botova N.D.
Published: January 2023

The program “State Final Attestation: Step Forward (online mode)” is one of the options for psychoprophylactic assistance to graduates in line with the formation of competencies that help ensure the psychological readiness of schoolchildren for the State Final Attestation. A feature of the course is the ability to implement it in an online format at all stages, relying on the interactive capabilities of online technologies using a combination of traditional methods (training, mini-lecture, discussion) and innovative methods implemented using modern technologies (interactive projective exercises, creation of a “digital story” by the participants). The program is effective as a prevention of stress factors associated with the need to comply with increased security measures, anxiety about the health of loved ones, with a decrease in the quantity and quality of direct communication. 36 students of comprehensive schools in the city of Chelyabinsk took part in the approbation of the program. The factor of personal interest and desire of graduates to participate in the program acted as a determining factor for participation in the program.

To accomplish these goals, the authors conducted a series of surveys and empirical analyses utilizing reliability analysis, validity check, regression model analysis and moderate regression model analysis.
Those analyses brought the result that Supply Chain Management practice has positive effect on the performance in Korean sample companies. Further research analyses showed the results that delegation of authority demonstrates positive moderating effect on relationship between Supply Chain Management practice and the performances, while job satisfaction does not. lt implies an managerial implication that implementing investments on and making efforts on Supply Chain Management practice and delegation of authority concurrently can provide companies with more improvement in the performance because of a synergistic effect between the two. Moreover, one possible reason that job satisfaction does not demonstrates synergetic effect can be explained by the characteristic that job satisfaction have to be sought over long, not short, time span to expect improvements in performance in connection with other types of managerial efforts or investments.

Published: January 2023

This study conducted keyword network analysis on domestic and international articles related to food cold chain to figure out major research issues reflecting influences of COVID-19 and to derive implications. For this purpose, 409 papers (8,166 keywords) were collected from the time the first paper was published in domestic and international journals in Scopus, Web of Science, and Korea Citation Index(KCI) to the overall publication period (international journals from 1996 to the end of April, 2022 and domestic journals from 2004 to the end of April, 2022). As non face-to-face food purchases through e-commerce have soared due to the prolonged COVID-19, researches on new technologies such as the IoT, machine learning, and blockchain are actively conducted in domestic and international papers. Recent international papers mainly deal with the subject of non face-to-face cold chain food transaction management, but domestic studies mainly have been conducted on online cold chain food purchase decisions. And this study presented the characteristics and future tasks of domestic food cold chain research through comparative analysis of domestic and international papers considering the COVID-19 period.
Ground-motion amplification in the Santa Monica area: Effects of shallow basin-edge structure

Published: January 2023

The 1994 Northridge earthquake produced ground motions in the northwest portion of the Los Angeles basin that were significantly larger than rock-site motions observed at locations just north of the basin. The Santa Monica area was hit particularly hard, with numerous structures being damaged or destroyed by the strong ground shaking. In this region, the basin-edge geology is controlled by the active strand of the east-west-striking Santa Monica fault, and virtually all of the structural damage occurred at or south of the fault location. We have used 2D finite-difference ground-motion simulations to investigate the effect of the basin-edge structure in amplifying ground response. Constraints on the basin-edge structure come from geologic cross sections, geophysical data, and seismological observations. Our simulations indicate that the shallow basin-edge structure (1 km deep) formed by the active strand of the Santa Monica fault creates a large amplification in motions immediately south of the fault scarp, in very good agreement with mainshock damage patterns, recorded ground motions, and locations of elevated site response. This large amplification results from constructive interference of direct waves with the basin-edge-generated surface waves and is quite similar to the basin-edge effect associated with the 1995 Kobe earthquake. In addition, we find that focusing effects created by the deeper basin structure (3 to 4 km deep) cannot explain the large motions observed immediately south of the fault scarp. This strongly suggests that the deep-basin focusing models proposed by Gao et al. (1996) and Alex and Olsen (1998) are not likely explanations of the observed pattern of ground-motion amplification in the Santa Monica area.
Evaluating the Impact of Inclusion Metakaolin and Silica Fume on the Green and Mechanical Properties of Low Calcium Fly Ash Concrete

Generally, low calcium fly ash concretes (FFACs) subjected to ambient temperatures exhibit low initial strengths. Thus, FFACs require higher temperatures to improve the monomer dissolutions, but that increases the energy consumption. Thus, this paper aims to evaluate the influence of the incorporation of different dosages of silica fume (SF) and metakaolin (MK) on the green and hardened properties of FFACs cured at room temperature of 21 ˚C. Slump and air content tests were applied to evaluate the green characteristics of the designed geopolymer concrete mixes (GPCMs). The hardened properties of FFACs were assessed in terms of compressive, flexural, and splitting tensile strengths at different curing ages. Outcomes revealed that the slump and air content of GPCMs declined with improving SF or MK percentages. The 28 days flexural, compressive, and splitting tensile strengths of FFACs manufactured with the optimum dosages of 20% MK and 10% SF cured at 21 ˚C were evidently higher than those of FFACs (100 % FFA) subjected to curing temperatures ranging from 10-to-50 ˚C. Also, the strength enhancement of MK was relatively comparable to those of SF with less requirement for superplasticizers.

Patients in randomized controlled trials (RCTs) must be successfully randomized to reduce or eliminate bias. Because pre-treatment symptoms have prognostic significance in cancer patients, qualitative and quantitative tools were developed to assess similarity of baseline pre-treatment symptoms across different treatment arms of RCTs as one measure of randomization success. Clinician-reported symptom data from two colorectal cancer RCTs, CO.20 and CO.17, were used to demonstrate the utility of a qualitative visualization tool and quantitative machine learning K-means tool, which grouped patients into clusters using baseline symptoms. Qualitatively, reflection bar graphs (RBGs) visualized potential imbalances in baseline symptoms (i) across treatment arms and (ii) by corresponding patient clusters identified within each treatment arm. RBGs found that the treatment arms for both RCTs had similar symptom profiles, while the lack of significant differences in the proportions of patients in each cluster across treatment arms further confirmed successful randomization. This paper details the creation of visualization, machine-learning, and statistical tools to compare baseline symptoms across RCT treatment arms, demonstrating that the CO.20 and CO.17 trials were successfully randomized by baseline symptoms and are comparable. These tools can therefore be implemented easily to ensure an extra layer of quality assurance of the randomization process for study assessment.

Published: January 2023

Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune disease of the central nervous system (CNS) that prompts immediate potent treatment. Delaying treatment could leave debilitating sequelae. As erythropoietin (EPO) has shown neuroprotective effects, we studied the effects of adding EPO to intravenous methylprednisolone (IVMP) in patients with acute attacks of NMOSD.
Methods: NMOSD cases with acute attacks were included. Cases of optic neuritis (ON) and those with myelitis were separated. After randomization [with block sizes of 2 (1:1 ratio)], the patients in the intervention group received IVMP 1000 mg/day and intravenous (IV) EPO 20000 U/day for five days. IVMP 1000 mg/day and normal saline (NS) were administered in the control group. Staged eye score and motor forces were evaluated in the patients with ON and myelitis, respectively, at the time of the attack and three months later. Primary patient allocation and clinical assessments were blinded to the physicians.
Results: Mean age of participants was 53.87 ± 11.53 years. At follow-up, in the ON arm, the median improvement in staged eye score was 2 in the control and 5 in the intervention group. The difference was significant (P < 0.001). In the myelitis group, none of the patients in the control group had improvement in motor forces. All the patients in the intervention group showed substantial improvement with minimal or no remaining weakness. The difference was statistically significant (P = 0.029).
Conclusion: The results show the possible benefit of adding EPO to the classic IVMP in attacks of NMOSD in both visual and motor aspects.
Trend of incidence and mortality of brain and central nervous system cancer in Iran from 1990 to 2017: A global burden of disease-based study
Authors: Abbastabar Hedayat
Published: January 2023

Background: Brain and central nervous system (CNS) cancers make up about 3% of all cancers around the world and are more common among men than women. Present study aimed to evaluate the occurrence trend of brain and CNS cancers in Iran from 1990 to 2017.
Methods: This study using global burden of disease (GBD) 1990 to 2017 data demonstrated the trend of incidence and mortality of brain and nervous system cancer in Iran. All-age, sex-based, age-standardized, age-specific (from 1990 to 2017), and age distribution of incidence and mortality rates of brain and nervous system cancer were estimated in Iran during 2017.
Results: Both incidence and mortality rates of brain and nervous system cancer increased from 1990 to 2005 in Iran, Eastern Mediterranean Region, and global level. During 1990, incidence and mortality rates of brain and nervous system cancer were higher in women than men, but gradually both rates increased in men and exceeded women in Iran. From 1990 to 2017, the value of age-adjusted rate was higher than all-age rate of brain and nervous system cancer. The most incidence and mortality of brain and nervous system cancer from 1990 to 2017 occurred in age group of > 70 and the least values were seen in 15-49-year-old group in Iran.
Conclusion: The brain tumor occurrence and mortality in Iran was higher than other Eastern Mediterranean Region countries. Incidence and mortality of this cancer has an increasing trend in Iran and this trend somewhat was independent from population aging.
