The Performance “Memory” in the Context of the Creative Searches of the Soviet Ballet Theater of the 1960s—1970s
Authors: Melovatskaya Anna E.
Published: April 2023

The period of the 1960s—1970s was the heyday of the Soviet ballet theater. At that historical stage, a whole generation of innovative choreographers worked in many theaters of the USSR, and their work was based on loyalty to traditions and willingness to present their own vision of the ballet theater development. The article addresses the past of the Soviet ballet theater and examines the early period of creativity of G.G. Malkhasyants (1937—2008), one of the choreographers of the sixties. The author reconstructs the ballet “Memory” — one of his early performances, staged at the Voronezh Opera and Ballet Theater in 1973. The performance was the opener of the One-Act Ballet Evening. The second performance was “Carmen Suite” by G. Bizet — R. Shchedrin, and the final of the Evening was “Naughty Ditties” by R. Shchedrin. The purpose of the reconstruction of the ballet, which has left the stage and does not have a video recording, is to determine the context of the era during which the performance was staged, and to recreate the very image of the performance.

G.G. Malkhasyants’ creativity has hardly been studied; scientific work in this direction has just begun. For the first time, the article uses materials from the choreographer’s family archive — newspaper reviews, pre-premiere and premiere reports, photos from rehearsals and performances, handbills and announcements of performances. The relevance of their introduction into scientific circulation lies in the need to analyze the works of innovative choreographers of the second half of the 20th century, in particular — to reconstruct performances that have left the stage and do not have a video recording.

In the 1970s, G.G. Malkhasyants put into practice his own idea and understanding of the staging process in choreography and developed various choreographic techniques and directing principles. His work reflects the continuity of the generation of choreographers of the 1960s in relation to the ballet theater of the 19th — first half of the 20th century and proves the need to rely on traditions and achievements of choreographers of the past. Considering G.G. Malkhasyants’ creative searches and experiments, it is possible to trace the main trends in the development of the Russian ballet theater of the second half of the 20th century. The study helps to understand the prospects for the modern choreographic art development.

Polymers’ performance, biodegradability and recyclability can be tuned during synthesis by adopting monomers with differ-ent chemical characteristics. Recent research has shown the aptness of enzyme hydrolysis to depolymerize polyester under mild conditions with respect to chemical approaches. Herein, we engineered a cutinase from T. cellulosilytica (Tc_Cut2NVWCCG) for improved thermostability (up to 91°C) and performance, and compared it with previously reported leaf-branch compost cutinase (LCCWCCG) for the hydrolysis of oligomers, aliphatic and aromatic polyester homopolymers and co-polyester. Higher hydrolysis rates were observed towards aliphatic with respect to aromatic homopolyesters. SEC-MS revealed that the hydrolysis of aliphatic/aromatic co-polyesters preferentially occurred at the aliphatic monomers, significant-ly reducing the molecular weight and changing the end-group composition. These results underline the importance of co-polymer composition in the bio-degradation of co-polymer systems. Moreover, it underlines the potential to use enzymes to selectively reduce the molecular weight of synthetic polymers and characterize the distribution of polyester co-polymers.

Published: April 2023

With growing interest in solid-state nanopore sensing—a single molecule technique capable of profiling a host of analyte classes—establishing facile and scalable approaches for fabricating molecular size pores is gaining considerable traction. The introduction of nanopore fabrication by controlled breakdown (CBD) has transformed the economics and accessibility of nanopore fabrication. Here, we present an Arduinobased, portable CBD device, with an estimated cost of less than 120 USD (≳10x cheaper than most laboratory implementations), to fabricate pores of less than 5 nm in diameter. Using this device, 40 pores with sizes between ~2.5 nm and ~12.6 nm diameter were fabricated. The device is constructed with offthe-shelf readily available components, powered through the same cable used for data transmission, and controlled using a highly customizable MATLAB application, which has capabilities encompassing pore fabrication, pore enlargement, and current-voltage acquisition for pore size estimation. This creates a holistically portable sensing platform when coupled with portable amplifiers: a critical step towards onfield solid-state nanopore sensing applications.
Switching Lead for Tin in the ‘De-Leadification’ of PbHfO3: Noncubic Structure of SnHfO3

Published: April 2023

The removal of lead from commercialized perovskite-oxide-based piezoceramics has been a recent major topic in materials research owing to legislation in many countries. In this regard, Sn(II)-perovskite oxides have garnered keen interest due to their predicted large spontaneous electric polarizations and isoelectronic nature for substitution of Pb(II) cations. However, they have not been considered synthesizable owing to their high metastability. Herein, the perovskite lead hafnate, i.e., PbHfO3 in space group Pbam, is shown to react with SnClF at a low temperature of 300 °C, and resulting in the first complete Sn(II)-for-Pb(II) substitution, i.e. SnHfO3. During this topotactic transformation, a high purity and crystallinity is conserved with Pbam symmetry, as confirmed by X-ray and electron diffraction, elemental analysis, and 119Sn Mössbauer spectroscopy. In situ diffraction shows SnHfO3 also possesses reversible phase transformations and is potentially polar between ~130-200 °C. This so-called ‘de-leadification’ is thus shown to represent a highly useful strategy to fully remove lead from perovskite-oxide-based piezoceramics, and opening the door to new explorations of polar and antipolar Sn(II)-oxide materials.

We developed the Interdisciplinary Science Program in Research and Entrepreneurship (INSPIRE) to address the changing career landscape that students with an interest in Physical Chemistry, Biophysics and Biochemistry face. Third and fourth-year undergraduate Chemistry and Physics students participated in a 4-week, hands-on program that introduced applications of biophysical and biochemical techniques to drug discovery, while simultaneously engaging in a crash course on entrepreneurship and pharma. The principal objective of the program was to introduce students to the interdisciplinary nature of Chemistry and Physics research in the Life Sciences while simultaneously introducing the idea of translating their future graduate work into a career in biotechnology.
Comparison of click-capable oxaliplatin and cisplatin derivatives to better understand Pt(II)-induced nucleolar stress
Authors: Guerrero Andres , O'Dowd Paul , Pigg Hannah , Alley Katelyn , Griffith Darren , DeRose Victoria
Published: April 2023

Pt(II) chemotherapeutic compounds have been used as predominant anticancer drugs for nearly fifty years. Currently there are three FDA-approved chemotherapeutic Pt(II) compounds: cisplatin, carboplatin, and oxaliplatin. Until recently, it was believed that all three compounds induced cellular apoptosis through the DNA damage response pathway. Studies within the last decade, however, suggest that oxaliplatin may instead induce cell death through a unique nucleolar stress pathway. Pt(II)-induced nucleolar stress is not well understood and further investigation of this pathway may provide both basic knowledge about nucleolar stress as well as insight for more tunable Pt(II) chemotherapeutics. Through a previous structure-function analysis, it was determined that nucleolar stress induction is highly sensitive to modifications at the 4- position of the 1,2-diaminocyclohexane (DACH) ring of oxaliplatin. Specifically, more flexible and less rigid substituents (methyl, ethyl, propyl) induce nucleolar stress, while more rigid and bulkier substituents (isopropyl, acetamide) do not. These findings suggest that a click-capable functional group could be installed at the 4- position of the DACH ring while still inducing nucleolar stress. Herein, we report novel click-capable azide-modified oxaliplatin mimics that cause nucleolar stress. Through NPM1 relocalization, fibrillarin redistribution, and γH2AX phosphorylation studies, key differences have been identified between previously studied click-capable cisplatin mimics and these novel click-capable oxaliplatin mimics. These compounds provide new tools to identify cellular targets and localization through post-treatment Cu-catalyzed azide-alkyne cycloaddition and may help to better understand Pt(II)-induced nucleolar stress. To our knowledge, these are the first reported oxaliplatin mimics to include an azide handle, and cis-[(1R, 2R, 4S) 4-methylazido-1,2-cyclohexanediamine]dichlorido platinum(II) is the first azide-functionalized oxaliplatin azide derivative to induce nucleolar stress.
FACTORS AFFECTING THE ADOPTION OF SECURE SOFTWARE PRACTICES IN SMALL AND MEDIUM ENTERPRISES THAT BUILD SOFTWARE IN-HOUSE
Authors:   Independent Researcher Ottawa Canada, Umeugo Wisdom
Published: April 2023

Software has grown enormously in value because of its wide use for domestic, public, and economic activities. Software must be secure because exploited software vulnerabilities can negatively affect individuals’ and organizations' financial, health, and economic well-being. Various authors recommended practicing a secure software development lifecycle (SSDLC) to ensure that software is released secured. Software small and medium enterprises (SMEs), the dominant software publishers, have not widely adopted the SSDLC. This study approached the problem of software SMEs’ inadequate adoption of SSDLC from an innovation adoption perspective based on the diffusion of innovation theoretical framework (DOI). Five DOI factors, relative advantage, compatibility, complexity, trialability, and observability, were assessed for significance to software SMEs’ intention to adopt SSDLC. A random sample of 200 participants from a population of software security decision-makers of software SMEs based in the United States that develop software in-house were surveyed via an online close-ended questionnaire. Relative advantage, compatibility, and trialability were statistically significant to SME SSDLC adoption intention. Complexity and observability were not statistically significant to SME SSDLC adoption intention. Trialability was the strongest predictor of SME SSDLC adoption intention. SME software security decision-makers may find that the results of this study help to determine the factors they should consider when deciding to introduce the SSDLC into their software development process. The result of the study has implications for practice and social change because increased SME SSDLC adoption potentially results in the development of more secure software and fewer software security incidents.

Published: April 2023

This work reports the modification of West Java natural bentonite as an effective adsorbent for rhodamine B dye. The modification was finished by sodium intercalation at room temperature to get low-energy preparation. Characterization of bentonite-modified adsorbent was used SEM, XRD, FTIR, and BET analysis. The material pore size and surface area were increased by 0.303 nm and 178.710 m2/g on Na-bentonite. The adsorption mechanism conformed well with the Freundlich isotherm model and pseudo-second-order kinetics equations. The adsorption process by thermodynamic analysis was endothermic and advantageous. Under the optimum condition of pH 6 (confirmed by pHpzc), initial dye concentration of 125 mg/L, and the adsorbent dosage of 0.09 g for 65 minutes, the Na-bentonite has a larger adsorption capacity (Qm) of 142.86 mg/g, while the different adsorbent dosages of 0.11 g for 75 minutes, the adsorption capacity of natural bentonite (Qm) reaches 140.85 mg/g. This work provides a method for establishing a low-energy preparation adsorbent of bentonite-based on Na intercalant as a low-cost and valuable adsorbent for waste dye removal.

Authors: Adetunji Ademola , Sabri Shamsul Rijal Muhammad
Published: April 2023

The classical Poisson distribution assumes equidispersion and this is hardly the case when given count observations. To improve efficiency and general applicability for dispersed data, this paper obtains a new mixing probability distribution using quadratic transmutation map on the weighed exponential distribution. The mixing distribution is used to obtain a new three parameter mixed Poisson distribution. The new distribution has unimodal shape with positive skewness and tends to zero speedily. Basic properties of the new distribution like the distribution function, moments, and dispersion index are obtained. Maximum likelihood estimates of the parameters of the distribution are obtained. Applications are made using four claims frequencies from different insurance companies. Results show that the new distribution gives a good fit in comparisons with some referred discrete distributions.

Published: April 2023

Greed is one of the most common features in human nature, and it has recently attracted increasing research interest. The purpose of this work is to study the age-specific characteristics of determining own greed and its evaluation in others. We continue our research on greed as a personal trait, the presence of which leads to the maximum satisfaction of our own interests, at the expense of the well-being of others or as a result ignoring their needs. The problem of greed gained momentum with the advent of the Covid-19 pandemic, people of all ages and social status were forced to redistribute their material and intangible resources, save and save,when the others, on the contrary, increased their wealth through economic changes. So how has this critical situation affected the greed in all age people and their assessment of the greed in others? The following methods were used in the study: correlation, comparative and qualitative analysis of the results obtained by the method of semantic differential, incomplete sentences, situational tasks and the author's method of determining greed. As a result, it is shown that young people more often than adults consider greed as a personality trait inherent in everyone. Adult subjects to a greater extent equate the greed for experiencing negative emotions - evil, fear and aggression. In both groups, greed is defined as own limitation that prevents one from enjoying a full life, but through greed you can control your expenses, save and be responsible for your consumer behavior. Researchers of young and mature age believe that the greed of others limits their ability to live comfortably, satisfy their desires, achieve goals and live in abundance. Young and adult people's assessment of their own greed and the greed of others is moderate. Self-assessment of own greed and assessment of the greed of family and friends are similar. The assessment of city and country leader’s greed is higher than their own assessment of greed.

Published: April 2023

The aim of the study was to adapt a very popular in the world screening questionnaire for assessment of children psychosocial functioning. Both (parent and youth) versions of Pediatric Symptom Checklist (PSC, Y-PSC) of M. S. Jellinek, J. M. Murphy et al. were validated in Ukraine so to find out their cross-cultural universality and usefulness. The total number of study participants was 532: 281 parents fulfilled PSC-Ukr and 251 children fulfilled Y-PSC-Ukr. The sample included ordinary children, ones from families with domestic abuse and small clinical sample. Clinical interview, Kinetic Family Drawings and Sentence Completion Test were used with PSC questionnaires. Methods of classical test theory, confirmatory factor analysis and ROC-analysis were used for tests validation. Adapted versions appeared reliable and valid but had unusually low cut-offs and two-factor structure (internalizing and externalizing symptoms without separate attention deficit factor). Weak economy, military actions and upbringing peculiarities can be the reasons of unusual cut-off and factor structure of adapted tests. This test will be useful for practitioners and researchers in mental health and social work areas. PSC-Uke Y-PSC-Ukr can be recommended for use with problematic populations like children from families with domestic abuse as these methods reveal forms and degrees of children’s psychosocial dysfunction through negative growth conditions.

Published: April 2023

After the beginning of the full-scale Russian invasion of Ukraine, the situation for families with young children with developmental delays or disabilities and children at risk was characterized by a significant loss of stability and predictability, which are necessary conditions for the child's development. The war destroyed the foundations of stable life, daily routines and relationships in families, on which the early childhood intervention is based. With the beginning of the war, the question arose about the ability of the early intervention service to carry out effective activities in support and accompaniment of families raising young children developmental delays or disabilities and children at risk. The purpose of the study was to determine the features of the functioning and possibilities of the early intervention service in support and accompaniment of families with young children in a war situation. A questionnaire was developed for the research. The analysis of the obtained results was carried out using the method of constant comparison. It has been proven that the early intervention service makes it possible to provide support to parents, ensure their awareness, emotional stability, sensitivity, and supports the parents' ability to "see" the child, understand his real needs. And this creates favorable conditions for the formation of child-parent relations, allows strengthening the existing and finding new family resources for experiencing traumatic events related to the war situation.

Belief in a Just World and Infantilism as Predictors of Subjective Well-Being
Authors: Kryazh Iryna , Baranov Vladyslav
Published: April 2023

The article describes the results of a study of belief in a just world, psychological infantilism, and suggestibility as predictors of subjective well-being. The collection of empirical data was carried out in August-September 2022 with citizens of Ukraine. The sample consisted of 71 people (71.8% - women). It was established: Personal beliefs in a just world is a significant predictor of cognitive and emotional components of subjective well-being. The change of residence forced by the martial law increases the emotional discomfort. At the same time, the negative impact of the change of residence on the emotional state of the individual is partially compensated by the strengthening of the personal beliefs in a just world. Psychological infantilism, primarily infantilism of coping behavior, is a negative predictor of subjective well-being. Suggestibility is not a significant predictor of subjective well-being. At the same time, it is directly related to the infantilism of coping-behavior and position of dependency. By supporting these manifestations of infantilism, suggestibility can make a certain contribution to reducing subjective well-being. The article discusses the limitations of empirical research.

Published: April 2023

Objetivou-se com esse estudo avaliar o efeito da terapia do cone de ouvido em cães para o controle do medo e ansiedade, especificamente sobre aspectos comportamentais e parâmetros clínicos. Assim, 13 cães com comportamento associado ao medo e ansiedade foram submetidos a sessões de aplicação de terapia do cone de ouvido, que ocorreu semanalmente, durante quatro semanas. A cada sessão, os cães foram avaliados clinicamente. Durante a anamnese, os tutores responderam um questionário sobre a frequência e intensidade do comportamento indesejado associado ao medo e ansiedade apresentados pelos cães durante a semana anterior à sessão. Em seguida, realizou-se exame físico completo dos cães e os parâmetros clínicos foram mensurados antes da aplicação da terapia (M1), e imediatamente após a sessão (M2). Tanto nos comportamentos mais frequentes, presentes ?60% dos cães (tremor, vocalização excessiva, comportamento autodestrutivo e agressividade), quanto nos menos frequentes (salivação excessiva, urinação e defecação em momentos e locais inadequados e comportamento destrutivo) foram observadas reduções em frequência e/ou intensidade. As frequências cardíaca e respiratória apresentaram redução entre os momentos, enquanto os outros parâmetros variam pouco ou não variaram, estando dentro dos limites normais para a espécie canina. A terapia do cone de ouvido mostrou-se satisfatória em diversos aspectos, apresentando redução das frequências cardíaca e respiratória, bem como mudanças comportamentais relacionadas à sensação de medo dos animais, proporcionando um relaxamento momentâneo em mais de 65% dos cães estudados.
Effectiveness of sleep hygiene strategies on sleep quality and level of stress among adolescents
Authors: Shital Pethkar-Padalkar , Bijayalakshmi Devi L.
Published: April 2023

Adolescents are developmentally vulnerable to sleep problems due to their transitional stage. According to the literature, recent lifestyle changes and poor sleep hygiene have increased the prevalence of sleep disorders. A quantitative approach with a pre-test and post-test control group design is used to assess the effectiveness of sleep hygiene strategies on sleep quality and the level of stress among adolescents. Sixty-four adolescents (51% male) in grade 9 are recruited using a probability-computerized simple random sampling technique and divided into experimental and control groups. The validity and reliability of the tool are established using Cronbach's alpha test. The experimental group received an online intervention on sleep hygiene strategies for 5 days, including Surya Namaskar and deep breathing exercises, while the control group received standard interventions per institute policy. The data is gathered using an online structured questionnaire that includes demographic variables, the sleep quality scale, and a stress scale at baseline (T0), immediately following the intervention (T1), and at the 1-week follow-up (T2). Both groups have kept an online sleep hygiene diary for the last 2 weeks. The findings showed that post-intervention sleep quality (T1 and T2) and stress levels (T2) are significantly (P < 0.05) higher than baseline (T0) levels in the experimental group. The result demonstrates that participants in the experimental group adhered to the recommendations made in the sleep hygiene diary. Hence, it was concluded that early detection of poor sleep hygiene and stress in adolescents is required for timely intervention. The implementation of sleep hygiene strategies is a novel approach to addressing a prevalent problem and can help motivate adolescents to adopt healthy sleeping habits.

Published: April 2023

O artigo retoma as discussões sobre a reflexão docente e as experiências vivenciadas em tempos líquidos (onde o clicativismo e mercantilização se fazem presentes) compreendendo-as como conhecimento significativo e potente para sua aprendizagem a partir da alternância (alter-ego). Deste modo, pensar sobre os impactos que as ferramentas digitais têm engendrado no cotidiano das escolas ao deparar-se com os sentidos ativos e hiperativos que o digital produz e seus latentes efeitos se faz necessário, pois a atenção ao conhecimento acadêmico parece ter sido perdida em detrimento das potencialidades oferecidas pelas redes. Sendo assim, olhar para o professor e seu espectro de ação (que inclui elementos da saúde mental, emocional, relacional, além de outros), se faz célere ao exercício formativo, pois, diz sobre o tempo de pensar, um debruçar na compreensão conceitual produtiva entre o homem e a máquina.

Brackish water in swelling soil stabilization with lime and sugarcane bagasse ash (SCBA)
Authors: Silvani Carina , Guedes João , Silva Jucimara , Tenório Eduardo , Nascimento Renan
Published: April 2023

This research shows that brackish water increases the unconfined compressive strength of swelling soil/sugarcane bagasse ash (SCBA)/lime blends. Therefore, brackish water may substitute tap water in soil stabilization. Sodium chloride (NaCl) has been used in lime-ashes-soil treatments. In northeast Brazil, swelling soils are usual and artesian wells sometimes provide brackish water containing NaCl. Northeast Brazil also has a strong sugar and ethanol industry producing sugarcane bagasse ash (SCBA) as a byproduct. Therefore, brackish water can be used in soil-SCBA-lime stabilization. Hence, this work aims to evaluate the use of brackish water as a substitute for tap water in swelling soil- SCBA-lime blends stabilization. Two series of unconfined compression tests were carried out: one with tap water and the other with brackish water. In each group, the lime content varied from 4% to 8%, and the dry density from 13 kN/m3 to 15 kN/m3. All tests were carried out with a swelling soil-SCBA proportion of 75/25 and a water content of 22%. Results have shown that increasing lime content or dry density or using brackish water allowed to increase unconfined compression strength of swelling soil-SCBA-lime blends. The porosity/volumetric content of lime index (η/Liv) was suitable to predict the unconfined compressive strength of swelling soil-SCBA-lime blends, no matter if tap or brackish water was used in the molding process. Thus, brackish can be a feasible substitute for tap water in swelling soil-SCBA-lime stabilization, increasing blends unconfined compression strength, and preserving tap water, a scarce asset in Northeast Brazil.

Se aplicó la Escala Latinoamericana y Caribeña de Seguridad Alimentaria, se recolectaron datos sociodemográficos, antropométricos y se compararon entre niveles de inseguridad alimentaria. Se calcularon razones de prevalencia para identificar factores sociodemográficos asociados a mayor riesgo de inseguridad alimentaria.  Resultados: Se encontró una alta prevalencia de sobrepeso + obesidad e inseguridad alimentaria de 86.4% y 76.1% respectivamente. Las personas con inseguridad grave presentaron mayor índice de masa corporal, índice cintura/talla y circunferencia de cintura; así como menor nivel socioeconómico y escolaridad del jefe del hogar. La presencia de menores de 18 años aumentó el riesgo de inseguridad alimentaria en 27% [RP=1.27; IC:1.02-1.58)]. Conclusiones: Los bajos ingresos económicos, la baja escolaridad del jefe del hogar y tener menores de 18 años incrementan la probabilidad de que los hogares se posicionen en alguna clasificación de inseguridad alimentaria.

Published: April 2023

The purpose of this study was to determine the effect of the diameter of the heat exchanger on the formation of fuel oil from plastic waste. The raw material for plastic is polypropylene (PP), which is used to package mineral water. The research method used is an experiment to make plastic oil by pyrolysis. The procedure uses a kilogram of polyethylene. The raw material is cut into small pieces before being put into the pyrolysis tube. The result of this study is that the maximum temperature of the reactor (Tmax) is inversely proportional to the diameter of the heat exchanger used. The average volume of fuel oil produced in each variation of heat exchanger diameter is 0.625 L, 0.8 L, and 1 L, respectively. The average calorific value of the fuel produced in pyrolysis with a heat exchanger diameter of 1/2 inch, 3/4 inch, and 1 inch, respectively, is 10899.67 cal/gr, 10945.33 cal/gr, and 11062.33 cal/gr.
