Radiation safety standards during 3D CBCT imaging: A review in dentistry
Authors: Bhateja Sumit , Thamman Sheena , Jasmine  , Arora Geetika
Published: March 2023

The development of cone-beam computed tomography (CBCT) technology altered the practise of oral and maxillofacial radiology. When compared to medical computed tomography, CBCT was quickly adopted in dentistry settings due to its small size, relatively reduced cost, and decreased ionising radiation exposure. CBCT referrals are still being made incorrectly due to a lack of sufficient education among dentists and specialists. Furthermore, in order to get high-quality pictures, operators may raise the radiation dose, exposing the patient to unnecessary hazards. The objective of this review is to give an insight into 3D imaging with CBCT technology and a prudent radiation monitoring during CBCT for the benefit of both patients and dentists.
Behavioural patterns of children as risk factors of oral hygiene and dental caries- A short study
Authors: Agarwal Nidhi , Jabin Zohra , Anand Ashish , Tanvir Zoya
Published: March 2023

Oral health is an important aspect affecting general health and quality of life. All children have different health considerations including oral health. Children have their own basic nature and this behaviour variability may influence their understanding and acceptability towards maintenance of oral hygiene. Some children may not follow the proper oral hygiene regimes due to variable behaviour which can drastically affect their oral status. Thus, the behaviour of child can act as an obstacle in maintaining oral hygiene.

The present study was aimed at finding the association of child behaviour with dental caries and oral hygiene status.

: A convenient sample of 100 children aged 6-11 years visiting the Department of Pediatric and Preventive Dentistry were taken for the study. A questionnaire was designed to assess the behaviour of children. Oral hygiene Index and Caries Index of the samples to be studied were recorded. The obtained data was tabulated and subjected to statistical analysis

A statistically significant association was found between child behaviour and dental caries(deft). Also, different types of behaviour pattern showed difference in oral hygiene and caries index. a correlation between oral hygiene and child behaviour was also found.

Oral health status has a multifactorial etiology with child behaviour as an influential factor. Especially in young children, it may directly or indirectly influence caries risk and oral hygiene status. If identified in initial phase, working upon it may help in promoting better oral health of children in the long run.

Published: March 2023

Background: Leafy vegetables could be contaminated with parasitic infective stages, making them possible sources of human parasitic infections. This study aimed to assess parasites contamination level among five different leafy vegetables collected from open marketplaces in Giza, Egypt.
Methods: Hundred vegetable samples were collected from dill, parsley, coriander, rocca, and mint (20 of each). Samples were processed using sedimentation and concentration methods and the sediments were examined as wet smears either unstained or stained with Lugol's iodine. Also, modified trichrome and Ziehl-Neelsen stains were used to detect Microsporidia spores and coccidian oocysts. Statistical software SPSS version 20 was used for data analysis.
Results: A total of 86% of the examined samples were found contaminated with parasite's eggs, cysts, oocysts, and larvae. Coriander was the most contaminated vegetable with contamination rate of 95% while dill was the least contaminated (80%). Also, protozoan parasites contamination rate (77.1%) was higher than helminths parasites contamination rate (22.9%). Entamoeba histolytica/dispar was the most prevalent parasite (40.6%) followed by Blastocystis hominis (39.5%), Ascaris lumbricoides (18.6%), Cyclospora spp. (15.11%), Giardia lamblia (11.6%), E. coli (9.3%); while Cryptosporidium spp., Iodamoeba bütschlii, Trichuris trichiura, Enterobius vermicularis, Fasciola, and hookworms’ eggs were the least prevalent parasites (1.1%).
Conclusion: Leafy vegetables in Giza, Egypt had an extremely high parasite contamination rate. So, consuming such vegetables without proper washing facilitates transmission of parasitic infections which could pose a major health risk to Egyptians.

Published: March 2023

Background: The demand for vegetable oils is on the increase. Deep frying is the commonest method by which vegetable oils are consumed. The aim of this study was to extract oil from an underutilized oil seed and compare its physicochemical properties, frying, and oxidative stability with those of commercial refined palm oil.
Methods: Oil was extracted from Monodora myristica seeds using a soxhlet fat extractor and the percentage oil yield was determined. The physicochemical, oxidative, and frying stabilities of the extracted M. myristica Seed Oil (MMSO) were evaluated based on the standard procedure of the Association of Official Agricultural Chemists and official methods and recommended practices of the American Oil Chemists Society and compared with those of commercial refined palm oil- Kings Vegetable Oil (KVO). Data were statistically analyzed using SPSS version 20.
Results: The oil yield of M. myristica seed was 37.64%. The refractive index, specific gravity, moisture content (%), and peroxide value (mEq/kg) were respectively 1.470, 1.468, 0.923, and 0.917 for MMSO; and 0.220, 0.253, 1.05, and 3.50 for KVO. MMSO had better oxidative stability and showed 80% lesser peroxide formation than KVO. The frying stability of MMSO was better as it showed a lower increase in FFA (28.4%) and peroxide value (9.54 mEq/kg) than KVO (45.99% and 26.19 mEq/kg, respectively) after frying.
Conclusion: Deteriorative effect of oxidation and polymerization was lower in MMSO than in KVO indicating MMSO to be superior frying oil suitable for repeated frying.
Usos sociais das TICs em dinâmicas de transnacionalismo e comunicação migrante em rede: uma aproximação à diáspora senegalesa no Sul do Brasil
Authors: Brignol Liliane Dutra
Published: March 2023

Mesmo que as relações entre Brasil e África tenham se estabelecido em meio a muitos processos sócio-históricos, o continente ainda representa um desconhecido no contexto brasileiro. O artigo parte de uma discussão sobre os conceitos de Atlântico Negro e diáspora, em sentidos mais híbridos de cultura e identidades, para pensar fluxos migratórios que reatualizam as relações entre os dois âmbitos. O texto integra pesquisa sobre comunicação e dinâmicas de migração entre Senegal e Rio Grande do Sul e tem o objetivo de explorar o processo de consumo das tecnologias da informação e comunicação por migrantes senegaleses em cidades gaúchas. A análise valoriza dois aspectos centrais assumidos pelas TICs no processo migratório: o papel de conexão transnacional e a consolidação de dinâmicas de comunicação em rede com implicações intra e interculturais.
O corpo como sintoma da cultura
Authors: Santaella Lúcia
Published: March 2023

Este artigo busca refletir sobre a contemporânea onipresença do corpo em todas as esferas da cultura. Para alguns autores, o corpo virou uma verdadeira obsessão. Está perturbadoramente em todas as partes. Indo além da mera constatação, o argumento que desenvolvo neste artigo é o de que o corpo está obsessivamente onipresente porque se tornou um dos sintomas da cultura do nosso tempo. Diferentemente dos sintomas histéricos do século XIX, que se davam no corpo, que marcavam o corpo, gradativamente esses sintomas foram crescendo até tomar o corpo ele mesmo como sintoma da cultura. Como o conceito de sintoma exige, o tratamento teórico da discussão que aqui se desenvolverá está baseado na psicanálise, especialmente de Freud e Lacan.

Abstrat:

This paper discusses the contemporary omnipresence of the body in every cultural sphere. For some authors, the body has become a real obsession. It is disturbingly everywhere. Going beyond the mere recognition of the problem, this article argues that the body is obsessively present because it has become a symptom of our cultural era. Different from the nineteenth century hysterical symptoms that occurred in the body, that marked the body, gradually these symptoms grew to the extent of turning the body itself into a symptom of the culture. As the concept of symptom demands, the theoretical treatment of this discussion is based on psychoanalysis, especially on Freudian and Lacanian discourses.

Cisneros, o poder e os limites da mídia
Authors: Arbex Jr. José
Published: March 2023

Na Venezuela, os meios de comunicação de massa funcionam como o principal articulador da oposição ao presidente Hugo Chávez. Por meio de seu empresário mais importante, Gustavo Cisneros, organizaram um fracassado golpe de Estado, em abril de 2002, e tentaram construir uma agenda política destinada a criar uma situação de ingovernabilidade do país. Sucessivas vitórias políticas de Hugo Chávez, consagradas pelos resultados do referendo revogatório de 15 de agosto de 2004, entretanto, demonstram claramente os limites da mídia como protagonista político, bem como a capacidade da sociedade de resistir organizadamente às tentativas de manipulação do imaginário. Trata-se de um caso particularmente importante para aqueles que tentam entender de que maneira funcionam as imbricações entre mídia e poder político.

Abstract:

In Venezuela, the broadcasting corporations work as the main organizers of the opposition to president Hugo Chávez. Articulated by their most important entrepreneur, Gustavo Cisneros, they organized an unsuccessful coup d'état, in April of 2002, and they tried to build a political agenda destined to create a situation of political and social chaos in the country. Successive political victories of Hugo Chávez, consecrated by the results of the revocatory referendum, of August 15, 2004, however, clearly demonstrated the limits of the media as a political protagonist, as well as the capacity of the society to organize itself in order to resist the attempts of manipulation of the imaginary. It is a particularly important case for those who try to understand how media corporations relate to political power.

Published: March 2023

As estruturas de um indutor acoplado com dois e três enrolamentos têm ganhado popularidade nas aplicações de conversores de alto ganho de tensão. Essas células permitem gerar uma infinidade de topologias de conversores. Porém, até o momento, não há uma discussão comparativa entre ambos os modelos. Assim, esse artigo apresenta uma avaliação de conversores CC-CC de alto ganho de tensão baseados na estrutura empilhada da topologia boost com indutor acoplado com dois e três enrolamentos. Para demonstrar as vantagens, desvantagens e limitação de cada técnica, inicialmente, se analisa o princípio de operação dos conversores Boost-Flyback empilhados, com dois e três enrolamentos de indutor acoplado e células multiplicadoras de tensão no conversor com três enrolamentos. Para isso, se considera a mesma relação de transformação do indutor acoplado, N = 3 e diferentes valores de razão cíclica (D) com o mesmo ganho de tensão (M). Posteriormente, verificam-se os ganhos estáticos dos conversores, seus respectivos esforços de tensão (Total Voltage Stress) e corrente (Total Current Stress). Além disso, uma comparação das topologias semelhantes também são apresentadas. A fim de validar as análises teóricas, três protótipos foram construídos em laboratório. Das topologias avaliadas, o melhor resultado de rendimento foi 95%. Por fim, a distribuição das perdas dos componentes foi elaborada com o intuito de demonstrar os benefícios de cada técnica.

Authors:   Instytut Nafty i Gazu – Państwowy Instytut Badawczy, Szpunar Tadeusz , Majkrzak Marcin ,   Instytut Nafty i Gazu – Państwowy Instytut Badawczy
Published: March 2023

W artykule przedstawiono sposób oceny rozkładu temperatury w produkcyjnym otworze geotermalnym w sytuacji dopływu mieszaniny wody złożowej (solanki) oraz – planowanego jako główny nośnik energii cieplnej – dwutlenku węgla w zakresie nadkrytycznych parametrów ciśnienia i temperatury. We wstępie podkreślono znaczenie ograniczenia emisji dwutlenku węgla do atmosfery, omówiono krótko charakterystykę przemian fazowych CO2 oraz przedstawiono sposób jego alternatywnego zagospodarowania. Zyskującym w ostatnich latach na popularności sposobem ograniczenia szkodliwego oddziaływania dwutlenku węgla jest jego wykorzystanie jako medium roboczego przy pozyskiwaniu energii geotermalnej, tj. wprowadzenie go do obiegu w układzie otworów (zatłaczającego i produkcyjnego) do wyeksploatowanych złóż węglowodorów (ropy lub gazu). W pracy zobrazowano zasady pracy takich otworów, przedstawiono korzyści wykorzystania w systemach geotermalnych dwutlenku węgla jako płynu roboczego oraz określono warunki niezbędne do efektywnego działania omawianego układu. Jednym z elementów publikacji jest bilans wymiany ciepła pomiędzy płynem przemieszczającym się ze złoża na powierzchnię a górotworem. W ramach rozwiązania problemu zaprezentowano model bilansowy przyjętych i oddanych ilości ciepła przez mieszaninę solanki i dwutlenku węgla w otworze geotermalnym. Przedstawione zostały ponadto procedury określania parametrów CO2 w funkcji ciśnienia i temperatury w odwiercie, w tym lepkość, gęstość i współczynnik przewodzenia ciepła w mieszaninie. Podano również sposób obliczania parametrów koniecznych do określenia współczynnika przejmowania ciepła pomiędzy cyrkulującym płynem a ścianą rury okładzinowej. Na potrzeby obliczeń założono, że temperatura na ścianie odwiertu zmienia się liniowo wraz z głębokością, tzn. zgodnie z tak zwanym gradientem geotermicznym. Podano też zależność umożliwiającą określenie ilości ciepła przekazywanego od górotworu do przepływającej mieszaniny solanki i CO2. Jako element końcowy przedstawiono zależność wielkości temperatury płynu wypływającego z otworu od jego głębokości całkowitej, przyjętego natężenia przepływu i zmiennych proporcji CO2 i solanki w składzie mieszaniny. Wszystkie obliczenia przeprowadzono z uwzględnieniem właściwości CO2 w zakresie parametrów nadkrytycznych ciśnienia i temperatury, wzięto w nich również pod uwagę stopień izolacji cieplnej odwiertu. Przedstawiona została procedura obliczeń, a wyniki przykładu obliczeniowego zestawiono w formie tabelarycznej i graficznej. Na ich podstawie podjęto próbę wskazania, który z rozpatrywanych parametrów wpływa najsilniej na końcową wielkość temperatury wypływającego z odwiertu płynu.

Published: March 2023

The aim of this study is to present the pathological lesions observed in a skeleton (male, about 35–38 years old) from Radom (Poland), dated to the 18th–19th century. Bone changes were observed in both femurs and both pelvic bones. The head of the femur is enlarged and deformed, described as “mushroom-shaped”, with areas of smooth cortex and cavities, or possible cystic residues. The neck of femur is short and thick. The bone shaft and distal epiphysis do not show any changes. The changes were also observed in both acetabularies of the hip joint (marginal bone formation, subchondral bone remodelling). Radiographic images show bilateral necrosis of the femoral head. There is a significant sclerotization of the femoral head, with a discrete visible crescent sign. These macroscopic and radiological changes match the symptoms associated with Legg-Calvé-Perthes disease. This is the first case of the disease described in bioarchaeological materials from Poland.
Using quartzofeldspathic waste to obtain foamed glass material
Authors: Kazmina Olga V. , Tokareva Anna , Vereschagin Vladimir
Published: March 2023

The present paper proposes a method for the processing of mine refuse non-ferrous metal ore in the production of foamed glass. The subject of this research is a low-temperature frit synthesis (<900 °C), allowing for the high-temperature glass melting process to be avoided. The technology for the production of frit without complete melting of the batch and without using glass-making units offers a considerable reductionin energy consumption and air pollution. It was found that material samples obtained with a density of up to 250 kg/m3 are of rigidity (up to 1.7 MPa) in comparison with the conventional foamed glass (1 MPa). This increased rigidity was due to the presence of crystalline phase particles in its interpore partition of less than 2 μm in size. Material with a density of 300 kg/cm3 is recommended for thermal insulation for the industrialand construction sectors. At densities above 300 kg/cm3 and a strength of 2.5 MPa, the purpose becomes heat-insulating construction material. The proposed method for obtaining a porous material from waste widens our choice of raw materials for foamed glass, whilst saving resources and energy.
Theoretical analysis of biogas potential prediction from agricultural waste
Authors: Achinas Spyridon , Euverink Gerrit Jan Willem
Published: March 2023

A simplistic theoretical study of anaerobic digestion in order to predict the biogas amount of agricultural waste is proposed. A wide variety of models exist, but most of them rely on algebraic equations instead of biochemical equations and require many input parameters as well as computation time. This work provides a simplified model that predicts the biogas amount produced and could be applied for agricultural energy feasibility studies for instance dimensioning bioreactors digesting animal waste slurries. The method can be used for other feedstock materials and repeated for other similar applications, in an effort to expand anaerobic digestion systems as a clean energy source.

Authors: Radhakrishnan T. K. , Sahoo Akaash , Chinta Sankar Rao
Published: March 2023

Process industries generate large amount of heat that needs to be transferred. Shell and tube heat exchangers are extensively used in industriesfor utilization of the heat energy generated from different processes. For definite utilization of this energy, the temperatures of the hot and coldfluids passing through the heat exchanger should be monitored and controlled efficiently. A proper model of heat exchanger is required for thepurpose of monitoring and control. The objective of the paper is to mathematically model the heat exchanger using system identification methodsand experimentally evaluate the effectiveness of two PID controller tuning methods such as Internal Model Control (IMC) and relay auto-tuningfor temperature control. The Auto Regressive–Moving-Average model with eXogenous inputs (ARMAX) model of the heat exchanger is obtainedfrom the Pseudo Random Binary Signal (PRBS) experiment performed on the heat exchanger system. The outlet temperature of the cold fluid isconsidered as the controlled variable. Based on the obtained model, PID settings are designed using the two tuning methods, and the closed loopresponses such as servo and regulatory are compared experimentally. It is seen from the experimental results that the IMC based controller showsbetter results than the relay auto tuning method in terms of time integral error (i.e., ISE and ITAE).
Modelling and control of crystallization process

Published: March 2023

Batch crystallizers are predominantly used in chemical industries like pharmaceuticals, food industries and specialty chemicals. The nonlinearnature of the batch process leads to difficulties when the objective is to obtain a uniform Crystal Size Distribution (CSD). In this study, a linearPI controller is designed using classical controller tuning methods for controlling the crystallizer outlet temperature by manipulating the inletjacket temperature; however, the response is not satisfactory. A simple PID controller cannot guarantee a satisfactory response that is why anoptimal controller is designed to keep the concentration and temperature in a range that suits our needs. Any typical process operation hasconstraints on states, inputs and outputs. So, a nonlinear process needs to be operated satisfying the constraints. Hence, a nonlinear controller likeGeneric Model Controller (GMC) which is similar in structure to the PI controller is implemented. It minimizes the derivative of the squared error,thus improving the output response of the process. Minimization of crystal size variation is considered as an objective function in this study. Modelpredictive control is also designed that uses advanced optimization algorithm to minimize the error while linearizing the process. Constraints arefed into the MPC toolbox in MATLAB and Prediction, Control horizons and Performance weights are tuned using Sridhar and Cooper Method.Performances of all the three controllers (PID, GMC and MPC) are compared and it is found that MPC is the most superior one in terms of settlingtime and percentage overshoot.

This review summarizes industrial applications of inorganic and organic polyvalent (hypervalent) iodine compounds. Inorganic iodate salts have found some application as a dietary supplements and food additives. Iodine pentafluoride is used as industrial fluorinating reagent, and iodine pentoxide is a powerful and selective oxidant that is particularly useful in analytical chemistry. Common organic hypervalent iodine reagents such as (dichloroiodo)benzene and (diacetoxyiodo)benzene are occasionally used in chemical industry as the reagents for production of important pharmaceutical intermediates. Iodonium salts have found industrial application as photoinitiators for cationic photopolymerizations. Various iodonium compounds are widely used as precursors to [18F]-fluorinated radiotracers in the Positron Emission Tomography (PET).

Relationship Obsessive Compulsive Disorder: A Systematic Review
Authors: MISIRLI Melis , KARADAYI KAYNAK Gamze
Published: March 2023

Obsessive Compulsive Disorder (OCD) is a disorder characterized by obsessions and compulsions and negatively affects the functionality of individuals. OCD symptoms with romantic relationship content have been investigated in the literature for the last 10 years. OCD symptoms with romantic relationship content are divided into two types: relationship-centered and partner-focused. The aim of this systematic review was to examine the relationship between OCD symptoms with romantic relationship content and individual and relational variables. Studies in the literature were reviewed in detail in order to evaluate the results regarding the relationship between OCD symptoms in romantic relationships and individual and relational factors. In the national and international literature, no systematic review study on this subject was found. Accordingly, studies published between 2012 and 2022 in internationally accepted electronic databases using the terms "relationship obsessive compulsive disorder", "relationship centered obsessive compulsive symptoms" and "partner focused obsessive compulsive symptoms" were reviewed. As a result of the search, according to the inclusion criteria, 12 empirical studies on the relationship between OCD in romantic relationships and individual and relational variables with full-text access and written in English were analyzed. The methodological characteristics and results of the 12 included studies are presented in this systematic review study. The results of the studies suggest that symptoms related to romantic relationships negatively affect the functioning of individuals similar to OCD. When the variables associated with obsessive-compulsive symptoms in romantic relationships are analyzed in individual and relational context, they are related to many factors such as psychopathologies, attachment styles, self and relationship satisfaction. In this context, there is a need for empirical studies carried out with clinical samples, exploring the effectiveness of psychotherapy and cross-cultural studies on obsessive-compulsive symptoms related to romantic relationships.

Science teachers’ informal reasoning regarding energy-related local socioscientific issues and factors influencing their informal reasoning
Authors: TEKİN Nurcan , ASLAN Oktay
Published: March 2023

This study examines the informal reasoning of science teachers about energy-related local socioscientific issues and the factors influencing their informal reasoning. Since socioscientific issues are open-ended and do not have a clear solution, socioscientific reasoning is considered important in discussions on these issues. Thirty-eight science teachers from the Central Anatolian Region of Türkiye took part in this qualitative descriptive study. Three scenarios were used in relation to energy-related local socioscientific issues (nuclear power plants, thermal insulation, and solar energy) for teachers’ reasoning. The teachers engaged in a reasoning process that focused on proposing solutions to local controversial dilemmas. Researchers asked teachers whether they agreed with these scenarios and to explain their reasons. Data were analysed using content analysis. Teachers' informal reasoning patterns were classified into three: rationalistic, emotive and intuitive reasoning. Also, factors influencing their reasoning were grouped according to SEE-STEP. The results of the study indicated that the science teachers mostly used rationalistic reasoning about the local socioscientific issues and environmental and economic factors affected their reasoning. Finally, the implications for reasoning on local socioscientific issues are discussed.
Understanding Max Weber
Authors: Malinkin Alexander
Published: March 2023

The book of the famous Russian sociologist L.G. Ionin about Max Weber attracts attention with its unusualness. The review describes various facets of its unusual genre, highlights and examines the levels of the author's consideration of his subject — the personality of an outstanding Western sociologist. It is concluded that the author applied the Freudian methodology to explain the twists and turns in the fate of M. Weber, since they are closely related to the intimate side of his life. The creative approach of L.G. Ionin to understand the hero of his “intellectual novel” in the context of his classic sociological doctrine is analyzed. In conclusion, the reviewer dares to make his own assumptions about what Max Weber's “drama of life” consisted of.
Soviet/Russian Publication Flow Dynamics Analysis for Physics Subject Area and 1980–2020 Period
Authors: Glushanovskiy Aleksey
Published: March 2023

The scientific document’s (published in USSR (until 1991) then in Russia) flow included in the SCOPUS database Subject Area «Pphysics and Astronomy») for the period 1980-2020 is considered. It is shown that the flow dynamics development, in general, corresponds to the dynamic’s development of this branch world flow, and the share of the Soviet / Russian part of it, without ever falling out of the “top ten”, is increasing, reaching the third place among all participants by 2020. The number of documents types included in this flow varies from three to ten, but more than 90% of the total is always document types: the journal article and conference proceedings, publication. From so these two types of documents are considered below. The analysis revealed a quantitative increase (after 2018) in the share of conference proceedings, with a corresponding decrease in the share of journal publications. The point of view was verified that this is a purely Russian feature associated with taking into account the results of scientific work, however, a similar trend was revealed in the world publication’s flow and in the publications flows of a number of another countries, although in the Russian publications flow it is more pronounced. In general, this phenomenon requires a special additional study. Next, the citations of journal articles included to the Russian document’ flow were analyzed. Citations for three publications flow (1980, 1990 and 2000 years) were analyzed separately. This analysis showed a noticeable decrease in the number of uncited documents in the flow of 2000, which indicates a general interest in Russian publications increase. At the same time, it was found that a twenty-year period is not enough to get a complete picture of documents citing for a certain year of publication, included to this interval. A separate analysis of the citing for published documents with and without foreign co-authorship was carried out. `It has been established that the uncited documents percentage among documents with foreign co-authorship is significantly lower, and the average citation is significantly higher. The citing documents authors affiliation for citing Soviet/Russian publications was also analyzed. It was found that more than 80% of citing documents do not have authors with Russian affiliation. At the same time, among the first three affiliation countries for the citing documents authors of all publications of the three years under consideration are the USA and Germany, as well as (once) Japan and China.
Brutto Assessment of the Early Stage of Research Activity
Authors: Aryngazin Askar
Published: March 2023

Indices are widely included in the tools of modern scientometrics. However, there is no reliable numerical criterion for distinguishing between the assessment of the level of various candidate or PhD dissertations, despite the huge differences, sometimes hundreds times, in impact indicators of journals in which work of different doctorates is published. The article discusses brutto evaluation at an early stage of research activity in a wider discourse using the example of a simple scientometric index of publications, ab-index. Case of its calculation, analysis of its features, role in stimulating and ensuring coverage, connection with research impact, comparison with Hirsch index, and recommendations for its use are given. We provide facts, data, reasons, invite to discussion, and illustrate that some indexes have a useful advisory function only if their status is indicated, their scope of applicability is delicately outlined, their place in the overall structure and processes is indicated, discrimination based on one or another index value is eliminated, and appropriate compensatory or transformational measures are deployed to development of scientific and technological ecosystem, instead ofengaging in the production of more indicators, characterized as a mechanism for suppressing knowledge, technologies, and competencies.
The image of the Russian clergy in the works of A.P. Chekhov
Authors: Lipuntsov Mikhail I.
Published: March 2023

The study is devoted to the consideration of the images of representatives of the clergy of the Russian Orthodox Church in the artistic work of A.P. Chekhov. The relevance is due to the problem of rejection of society from the Church in the second half of the XIX century. The purpose of the study is to show the features of the image of church life in the works of art by A.P. Chekhov. With the help of tables, the types of clergymen and their assessment by the writer and his characters are demonstrated. The relationship between secular society and the clergy that developed in the second half of the 19th century is considered. In the writer’s work, it is impossible to single out negative, positive or transitional types of clergy, since often the assessment of one or another clergyman by one of the characters and/or a group of persons in the narrative is subjective, which cannot be said about the narrator, whose assessment is often positive and sympathetic. The conclusions made by protopresbyter Alexander Schmemann in a lecture recorded on audiotape in the 1970s are analyzed and substantiated. in San Francisco. It is concluded that only A.P. Chekhov in the second half of the 19th century managed to truly discern and depict in Russian fiction a “living” priest with his essence: the inner spiritual world and relationships with others.
Gamification elements in event marketing
Authors: Romashkin Viktor A.
Published: March 2023

We consider the specifics of using gamification elements in event marketing from the standpoint of involving and retaining participants in special event. Gamification is defined as the use of game mechanics in non-game situations. Gamification techniques are used in education, business, and marketing. In the promotion system, gamification techniques demonstrate consistency in the struggle of companies and brands for the attention of the audience. The work clarifies the boundaries of the concepts of “game” and “gamification”. As the established practice shows, gamification can be used at various stages of the implementation of special event: at the stage of announcement, at the stage of greeting and meeting participants before the start of event, gamification elements can be included in the structure of individual blocks of special event. Gamified solutions can be used to collect feedback at the end of event. When using gamification elements in event marketing, it is important to follow a number of rules, namely: gamification should have a clear, achievable goal that is relevant for the player; gamification rules should be clear to participants; gamification should have simple tasks to complete; game mechanics should fully and accurately reflect the progress of the player; you cannot completely turn the gamification process into a game and offer only virtual achievements for participation, etc.

Este livro contém dados de pesquisa sobre variáveis socioeconômicas, de saúde física e mental, psicológicas e sociais associadas à prevalência e a incidência de fragilidade em amostras de idosos residentes na cidade de Campinas (SP) e no distrito de Ermelino Matarazzo, na Grande São Paulo. A fragilidade é uma síndrome multifatorial e multideterminada que resulta em aumento da vulnerabilidade dos idosos à incapacidade, a doenças crônicas, às demências, à depressão e ao isolamento social. Prediz de forma robusta quedas, hospitalização, institucionalização e mortalidade em 2 a 3 anos. As pesquisas foram conduzidas por pesquisadores da Universidades Estadual de Campinas e da Escola de Artes, Ciências e Humanidades da Universidade de São Paulo. Uma adequada gestão da fragilidade em pessoas idosas por agências públicas e privadas de assistência à saúde requer intervenções precoces nos fatores de risco evitáveis para acometimentos que prejudicam o bem-estar dos mais velhos. Acreditamos que a ciência pode ajudar na produção de protocolos de intervenção e de investigação úteis ao manejo da fragilidade.

Exploitation of geothermal taonga at Ohaki has resulted in irreparable damage to whānau land, tribal land and the marae reservation, including major land subsidence, devastation of wāhi tapu, and groundwater impacts. The whānau, determined to shift from grievance mode to (eco)development mode, are committed to caring for and regenerating their whenua. This article outlines a whānau journey of re-establishing papakāinga. Their narratives provide insights and key eco-development factors which provide a blueprint for resilient whānau-based living, based on the practice wisdom of their tūpuna. Key factors include: whakapapa, whenua, whanaungatanga; science, technology and innovation; and partnerships and collaboration. These components and the overall model have been tested in the context of another whānau grouping whose positive feedback and applicability of the model gave the authors confidence to share it wider. Hopefully encouraging other whānau to consider papakāinga establishment, and more confident in determining their own resilient futures.

Alfalfa (Medicago sativa L.) is the most cultivated forage legume around the world. Under a variety of growing conditions, forage yield in alfalfa is stymied by biotic and abiotic stresses including heat, salt, drought, and disease. Given the sessile nature of plants, they use strategies such as differential gene expression to respond to environmental cues. Transcription factors control the expression of genes that contribute to or enable tolerance and survival during periods of stress. Basic-leucine zipper (bZIP) transcription factors have been demonstrated to play a critical role in regulating plant growth and development as well as mediate the responses to abiotic stress in several species, including Arabidopsis thaliana, Oryza sativa, Lotus japonicus, and Medicago truncatula. However, there is little information about bZIP transcription factors in cultivated alfalfa. In the present study, 237 bZIP genes were identified in alfalfa from publicly available sequencing data. Multiple sequence alignments showed the presence of intact bZIP motifs in the identified sequences. Based on previous phylogenetic analyses in Arabidopsis thaliana, alfalfa bZIPs were similarly divided and fell into 10 groups. The physicochemical properties, motif analysis, and phylogenetic study of the alfalfa bZIPs revealed high specificity within groups. The differential expression of alfalfa bZIPs in a suite of tissues indicates that particular bZIP genes are specifically expressed at different developmental stages in alfalfa. Similarly, expression analysis in response to ABA, cold, drought, and salt stresses, indicates that a subset of bZIP genes are also differentially expressed and likely play a role in abiotic stress signaling and/or tolerance. These expression patterns were further verified by qRT-PCR. However, further functional characterization of bZIP transcription factors in alfalfa will help illuminate the role they play in stress tolerance mechanisms in legumes and facilitate the molecular breeding of stress tolerance in alfalfa.
Development of a Computational Fluid Dynamics Model for Ice Formation: Validation and Parameter Analysis

Published: March 2023

In the history of civil aircraft transportation, ice formation has been identifies as a key factor in the safety of flight. Anti-icing and deicing system have emerged through the years with the aim to prevent or to eliminate ice formation on wing airfoil, control surface and probes. Modern flying machine demand more efficiency in order to reduce the carbon footprint and increase the sustainability of flight transport. In order to achieve this goal the need to have efficient aircraft with efficient and low power consuming system is fundamental. This paper proposes a new model for ice accretion using computational fluid dynamics (CFD). This model permits to simulate the shape of the ice formed over a profile varying boundary conditions (i.e.- speed, liquid water content and so on). The proposed model takes into account also the amount of heat transferred between water and the surrounding environment and includes the effects of air turbulence on the ice formation process. The CFD simulations have been validated with NASA experimental outcome and show good agreement. The proposed model can be also used to investigate the effects of various parameters such as air speed, Liquid Water Content and air temperature on the ice formation process. The results evidences that the proposed model can accurately predict ice formation process and is suitable to optimize the design of anti-icing or deicing system for aircraft and helicopters. This approach is not limited to aerospace but can also be exported to other applications such as transportation, wind turbine, energy management and infrastructure.

Background: Bibliometric analysis provides insight into knowledge gaps of a specific field. We want to know what part of medical care has been the subject of research in a group of Mexican physicians. The Instituto de Seguridad y Servicios Sociales de los Trabajadores del Estado (ISSSTE) cares for a wide spectrum of disease and it provides a unique vision of what specialists has investigated about health. Methods: Papers belonging to “ISSSTE” affiliation were harvested and downloaded to .csv Excel files from the Scopus database including most bibliometric variables. VOSviewer, biblioshiny and bibliometric were used to conduct the bibliometric. Results: 2,063 papers were found and re-trieved; internal medicine had the greatest number of papers with 831; nine institutions were listed claiming “ISSSTE” as their mother affiliation; original papers represent 82% of the total and 52% of them were written in Spanish. Research production in Mexico City and the most productive center is Centro Médico Nacional 20 de Noviembre. Discussion: We identified main institutions, prolific authors, top-cited researchers and their affiliations, however, our paper is a call to action for the medical community in Latin America to join our efforts in building a solid group of researchers for the future of science.
Microbiome and Volatile Metabolic Profile of Acetic Acid Fermentation using Multiple Starters for Traditional Grain Vinegar

Published: March 2023

Traditional grain vinegar is fermented using multiple acetic acid bacteria (AAB) at various temperatures. A single AAB showed high acid–producing ability at 30 °C with a 5% alcohol concentration and an initial pH adjusted to 4.0. Multiple AAB were similar to single AAB, but the optimal initial pH was 3.0. Acid production ability according to the type of AAB was higher in multiple AAB than that for single AAB. That is, using multiple AAB helped to increase the titratable acidity of traditional grain vinegar. In addition, increasing the titratable acidity and content of volatile flavor compounds was advantageous when two, rather than four, AAB types were mixed and used. Titratable acidity was high at medium temperatures (30 °C), but volatile flavor compounds increased at low temperatures (20 °C) under multiple AAB. A 16S rDNA–based microbiome taxonomic profiling analysis identified differences in beta diversity due to multiple AAB and fermentation temperatures. In particular, beta diversity analysis revealed a specific pattern when a mixture of Acetobacter ascedens GV–8 and Acetobacter pasteurianus GV–22 were fermented at low temperature (20 °C). Therefore, we propose the application of multiple AAB with acidic and flavor–producing properties in traditional grain vinegar.
Historic Syrian Cities in the Post-War Period: Balancing Cul-tural Preservation and Tourism Investment
Authors: Noaime Emad
Published: March 2023

This paper explores the challenges and opportunities of balancing cultural preservation and tourism investment in historic Syrian cities in the post-war period. The Syrian conflict has caused significant damage to the country's cultural heritage, including its ancient cities, which are UNESCO World Heritage sites. Key issues raised include what challenges local governments to face, the impact of the war on the preservation of historic sites, how tourism can be used as a tool for economic development, and how to ensure that cultural heritage is preserved while also allowing for tourism investment. To gain an in-depth understanding of the old Syrian cities, extensive research has been conducted, including a review of existing literature and interviews with key stakeholders. The researcher found that rebuilding historic Syrian cities is a complex task that requires balancing cultural preservation with tourism investment. It will require collaboration between government officials, preservationists, developers, and local communities to ensure that these cities are restored in a way that respects their history and culture while also promoting economic growth through tourism.
