Published: March 2022

Von Willebrand's disease (VWD) bleeding is less likely to endanger life, unlike hemophilia. The lack of a significant decrease the quality of life leads to decrease in the compliance of patients with VWD. To improve the situation, the staff of the Department of Hemostasis Disorders, Russian National Research Center for Hematology conducted this program in Moscow and the Moscow region. Determine the patients' compliance to therapy, as well as the difficulties and wishes associated with the treatment of VWD. Survey of patients with VWD on a visit to a hematologist or via phone calls. Questions included information on diagnosis, safety, efficacy, and convenience of replacement therapy, communication, bleeding control, and social standing. The study was approved by the Independent Ethics Committee and the Scientific Council of the National Medical Research Centre for Hematology of the Ministry of Healthcare of the Russian Federation. 41 patients took a part in it: 17 male and 24 female. The majority of initial visits to a specialist are associated with bleeding from the nose and gums (26%), with hematomas (20%), dental operations (13%) and injuries (11%). Most often, the diagnosis was installed by a pediatrician (47%), less often by a surgeon (14%) or genetic inheritance (14%), gynecologists (9%), dentists (7%), otorhinolaryngologists (2%) and doctors of other specialties (7%). Completely satisfied with the therapy are 76% of the respondents. However, one patient considers the therapy ineffective. VWD is the most common coagulopathy, which can be encountered by a doctor of any specialty. Our survey identified a need to educate patients about intravenous injections. The communication between patient and doctor and the therapy correction on time could be improve compliance and reduce the cost of the state for the treatment of complications associated with non-compliance of patients.

Authors: Abdullah Suhaib Q. , Abdullah Ahmed N.
Published: March 2022

The Harmonic Oscillator (HO) and Gaussian (GS) wave functions within the Binary Cluster Model (BCM) were employed to investigate neutron, proton and matter densities of the ground state as well as the elastic proton form factors of one neutron 8Li and 22N halo nuclei. The long tail is a property that is clearly shown in the neutron density. The existence of a long tail in the neutron densities of 8Li and 22N indicates that these nuclei have a neutron halo structure. Moreover, the matter rms radii and the reaction cross section  of these nuclei were calculated using the Glauber model.

Good and God: The Enlightenment Projects in Europe and China
Authors:   Faculty of Humanities, University of Manchester, Manchester, UK, Lee Keekok
Published: March 2022

This paper will explore the following themes: (1) To argue that the concepts of Good and God belong to distinctly different discourses – the former to ethics or moral philosophy, the latter to religion; (2) There is no necessary logical link between Good and God; (3) Far from God logically preceding Good, it is Good which logically precedes God and guarantees its existence as a supernatural entity; (4) From above it follows that a society can be moral and not subscribe to a religion which postulates the existence of God as a supernatural entity; (5) Chinese history, its culture and its civilisation which have lasted and continues to endure for at least two and a half thousand years constitutes a refutation of the thesis that there can be no morality without religion and that a society resting solely on Good and not God could survive; (6) European Enlightenment which occurred in the 18th century is about dispensing with God and religion, ushering in secularism and humanism as an alternative philosophical foundation for society; (7) The Chinese has been secular and humanistic since the Spring and Autumn period when Kongzi and other philosophers lived and taught. This means that the Chinese Enlightenment Project has occurred, more than two thousand years before the European Enlightenment Project; (8) Furthermore, there is compelling circumstantial evidence that the Chinese Project could have played a role in the emergence of the European Project via the Jesuit route of knowledge transmission from the East to the West.

Published: March 2022

For modern universities, social media is a competitive environment and a platform to increase their brand awareness in global and national rankings and promote educational, scientiﬁc and innovative services to a social media audience using marketing tools. The positioning of a modern university in social media is an activity focused on presenting the university and its services in the most advantageous way, popularising science. The aim of the study is to examine global trends in the positioning and digital transformation of university media activity in social media based on open statistical data. The authors analysed university presence indices in eight social networks (VK, Instagram, Facebook, YouTube, Telegram, Twitter, OK, Tik-Tok) of universities from the top 10 media activity rankings (2021), taking into account the speciﬁcs of each social network. The universities with the maximum media presence in each social network are highlighted. It is noted that a prominent presence on social media is based on working on the university’s positive media image and implementing global media positioning trends into strategic development. Two different strategies for positioning in the media space have been detected, and social networks with great potential for positioning higher education institutions in terms of age and the market segment capacity they cover are noted. The study can be useful to sociologists, economists, marketing experts and university professors.
Opportunities and threats of digital transformation management education
Authors: Krotenko T. Yu.
Published: March 2022

The changes taking place in the world presuppose the inevitable entry of business, science, education into the digital space. For such a serious step, Russian organisations in any ﬁeld of activity need a comprehensive readiness of the entire system, supported not only by the enthusiasm of employees and the ability of managers to experiment. Without thoughtful high-quality preparation of all system elements and connections, digital transformation can turn out to be an untimely costly measure that hinders the development of organisations. The article analyses the barriers to the economic digitalisation and management education that affect the digital transition success. Education is viewed as a leading factor in socio-economic development, therefore, the demand for digitalisation is addressed primarily to education. The article raises the problem of the lack of a convincing scientiﬁc psychological and pedagogical concept of digital learning, which could be used by subjects of education as a basic one. The results of a students’ survey of management specialties of the university showed: the professional competencies of modern managers necessary for activities in the era of the digital revolution have to be expanded, the question arises of the reasonable disciplines inclusion that correspond to real needs in the educational programs of the management university.
Autonomous retrosynthesis of nanoscale structures via spectral shape matching
Authors: Vaddi Kiran , Chiang Huat Thart , Pozzo Lilo D
Published: March 2022

Synthesizing complex nanostructures and assemblies in experiments involves careful tuning of design factors to obtain a suitable set of reaction conditions. In this paper, we study the application of Bayesian optimization (BO) to achieve autonomous retrosynthesis of a specific nanoparticle or nano-assembly structure, shape, and size starting from a set of reagents selected a priori. We formulate the BO as a shape matching problem given target spectra as a structural proxy with a goal to minimize the shape discrepancy. The proposed framework is grounded in analyzing the spectra as belonging to function spaces and a Riemannian metric defined on them. The metric decomposes spectral similarity into amplitude and phase components and provides a near convex function to optimize as opposed to nearly flat functions produced from the commonly used mean squared error (MSE). Applying the framework to both experimental and simulated spectra, we demonstrate the advantage of shape matching over MSE and other generic functional distance measures.
Unraveling Molecular Assembly and Tracking Lipid Droplets Dynamics using Fluorescent Phenanthroimidazole Derivatives

Published: March 2022

A judicious structural modification of molecular building units imparts significant variation in the evolution dynamics of supramolecular self-assembled architectures and their functional properties. The incorporation of alkyl chains into the rigid and π-conjugated molecular backbone not only directs the self-assembly but also enhances the hydrophobicity of the probe, facilitating specific interactions with hydrophobic organelle like lipid droplets (LDs). Such a fluorescent molecular probe is ideally suited for elucidation of complex self-assembly processes and to decipher the intracellular dynamics of LDs. Invoking the concept, the main skeleton of 1,4-bis(1H-phenanthro[9,10-d]imidazol-2-yl)benzene abbreviated as BPIB, was functionalized with a varying number of octyl chains to obtain BPIB1 and BPIB2. The alkyl chains were crucial to circumvent the π-π stacking leading to the strong fluorescence in aggregates and solid-state. Contrary to BPIB and BPIB2, intermolecular interactions-driven spontaneous self-association of BPIB1 having an amine nitrogen center and a long alkyl chain resulted in a stimuli-responsive fluorescent organogel. We deciphered the reversible morphological transformation between supramolecular fibers and spherical nanoaggregates using fluorescence lifetime imaging microscopy. The gradual progression in the fluorescence lifetime provides a unique strategy for exploring the dynamics of the self-assembly process. Furthermore, BPIB1 was found to be a specific marker for LDs in multiple cell lines. The fluorescence correlation spectroscopy revealed the microenvironments near LDs. Highly photostable BPIB1 was employed for the real-time tracking of the LDs dynamics in live cells. Thus, a combined microscopic and spectroscopic approach demonstrated in the present study opens up new avenues for further exploration of intriguing molecular aggregation and intracellular dynamics.

Authors: Matar Samir F. , Etourneau Jean , Solozhenko Vladimir L.
Published: March 2022

The purpose of this work is to predict the existence of novel equiatomic SiCN based on tetragonal C6 structure (“glitter”), the elementary building unit being the 1,4 cyclohexadiene molecule comprising both tetrahedral (sp3) and trigonal (sp2) carbons. From crystal chemistry rationale the structural transformations of C6 to SiC2 and then to the ternary SiCN were fully relaxed to the ground states using first principles DFT-based calculation. Like early proposed C6 and SiC2, SiCN was found bonding and structurally stable from the elastic properties on one hand and dynamically stable from the phonons, on the other hand. The Vickers hardness of SiCN is close to that of cubic silicon carbide, a conventional superabrasive, whereas hardness of tetragonal SiC2 is slightly lower. Besides the abrasive properties, the electronic band structure indicates metal-like behavior of SiCN thus suggesting the potential for heat dissipation in operating conditions.
Strategy facilitating the transfer of zirconium-oxide nanotubes onto zirconia-based ceramic implants
Authors: Vakamulla Raghu Swathi Naidu , Hartwich Patrick , Pritzel Christian , Killian Manuela S
Published: March 2022

We report on the synthesis route for metal-oxide nanotubes via electro-chemical anodization of zirconium foil resulting in the formation of zirconia nanotubular (ZrNT) films, subsequently transferred onto pre-formed zirconia (ZrO2) implant material. The approach was based on a direct transfer of ZrNT films onto the ceramic implant via an acetone bath. The ZrNT film was detached from the metal-foil using regular adhesive-tape prior to transfer. This simple technique allows to impart a robust micro-nanoscale structure to bulk-ceramics that can potentially offer enhanced surface-reaction sites and functionality in the field of ceramic-biomaterial applications.

Published: March 2022

Deep eutectic solvents (DES) are an attractive class of materials with low toxicity, broad commercial availability, low costs and simple synthesis, which allows for tuning of their properties. We develop and demonstrate the use of high-throughput and data-driven strategies to accelerate the investigation of new DES formulations. A cheminformatics approach is used to outline a design space, which results in 3,477 hydrogen bond donor (HBD) and 185 quaternary ammonium salt (QAS) molecules identified as good candidate components for DES. The synthesis methodology is then adapted to a high-throughput protocol using liquid handling robots for the rapid synthesis of DES combinations. High-throughput electrochemical characterization and melting point detection systems are used to measure key performance metrics. To demonstrate the new workflow, a total of 600 unique samples are prepared and characterized, corresponding to 50 unique DES combinations at 12 HBD/QAS molar ratios. After synthesis, a total of 230 samples are found liquid at room temperature and further characterized. Several DES display conductivities above 1 mS/cm, with a maximum recorded conductivity of 13.7 mS/cm for the combination of Acetylcholine Chloride (20 mol %) and Ethylene Glycol. All liquid DES samples show stable potential windows greater than 3 V. We also demonstrate that these DES are electrochemically limited by viscosity, both in the conductivity and in the limiting processes on their cyclic voltammograms. Comparison with literature reports show good agreement for properties measured in the high-throughput study, which helps to validate the workflow. This work demonstrates new methods to accelerate the collection of key DES metrics, providing data to formulate robust property prediction models and obtaining insight on interactions between molecular components. Data-driven high-throughput experimentation strategies can accelerate DES development for a variety of applications. Moreover, these approaches can also be extended to tackle other materials challenges with large molecular design spaces.

Published: March 2022

The anticonvulsant activity of 2-aminoethanesulfonic derivatives - magnesium bis-acetamino-2-aminoethanesulfonate (LHT-317) and zinc cyclo-bis-acetamino-2-aminoethanesulphonate (LHT-318) derivatives was studied in the model of pilacorpine epileptogenesis. The studies were performed on 30 white laboratory rats, in which epilepsy was modeled by intraperitoneal administration of pilocarpine hydrochloride at a dose of 320 mg/kg. Within 4 weeks after the formation of epilepsy rats were got intragastrically LHT-31, LHT-318 and Carbamazepine at doses of 2.5% and 5% of the LD50 determined for rats with this route of administration. Carbamazepine was used as the reference drug. The frequency, duration and severity of seizures were assessed using the Krushinsky scale. Morphological studies of the brain in the hippocampus and dentate sulcus were profiled by Nissl staining using 0.4% cresyl violet. The results were evaluated using an Olympus Bx50 digital microscope, x400 magnification over an area of 1000 µm2. The zinc salt of 2-aminoethanesulfonic acid LHT-318 exhibited anticonvulsant properties: it reduced the severity of acute convulsive paroxysm, prevented the formation of spontaneous convulsive activity, and was comparable in activity to the reference drug carbamazepine. LHT-317 did not demonstrate antiepileptic activity in this model. Compounds LHT-317 and LHT-318 at course administration prevented the depth of morphological changes characteristic of pilocarpine epileptogenesis, while it should be emphasized that complete prevention of morphological disorders is not observed in any case. Thus, based on the study, we can conclude that the zinc cyclic salt of 2-aminoethanesulfonic acid can be considered as a potential drug for the treatment of epilepsy.

FUNDAMENTAL CONCEPTS AND RECENT APPLICATIONS OF FACTORIAL STATISTICAL DESIGNS
Authors: MAINARDI Pedro Henrique , BIDOIA Ederio Dino
Published: March 2022

Factorial designs have been increasingly used in scientific investigations and technological development. The designs, through the use of matrices with all the treatment combinations, have been capable to effectively characterize the relationships between the variables of multi-factor experiments, assess the experimental variabilities, and derive mathematical functions that represent the behavior of the responses. Factorial designs were fractionalized, which substantially reduced the number of treatments without the loss of relevant information. The addition of central and star points to the factorial arrays has given them the orthogonality and rotatability characteristics, frequently used to fit models with curvature and identify critical regions of interest. Literature reports indicated that factorial designs, also called factorial experiments, were successfully applied in different types of investigations, including in cost evaluations and time-series studies. They were capable to estimate important features of the experiments, like the individual and combined effects of factors, the magnitude of residuals, additionally to express the relationships of the variables in polynomial equations, draw response surface and contour plots, and determine optimal combinations of parameters. In this review, the fundamental aspects of the Complete, Fractional, Central Composite Rotational and Asymmetrical factorial designs were conceptualized, and recent applications of these powerful tools were described.
MAN AND THE WORLD IN A SITUATION OF CHANGE: A TRANSDISCIPLINARY APPROACH
Authors:   Psychological Institute of the Russian Academy of Education, Guseltseva Marina S.
Published: March 2022

The problem of studying the transformations of modernity is relevant today in psychology and social sciences. The most well-founded changes in man and the world were considered in international anthropology, starting from the second half of the twentieth century. At the specific scientific level of methodology, research strategies were developed here and new directions arose – anthropology of contemporary, anthropology of globalization, anthropology of the future. At the general scientific level of methodology, the instrument for studying the transformations of man and the world is a transdisciplinary approach that integrates the studies of psychology and social sciences. At the same time, transdisciplinarity manifests itself today not only as a conscious methodological strategy, but also as a spontaneous practice in a problem-oriented cognitive space. The issues of identity formation, socialization of the younger generations, personal development in the context of globalization and in a situation of change constitute today the general problem field of psychology, anthropology and other social sciences. Psychology in this cognitive context is able to expand the horizon of ideas about man and the world, including through the reception of modern anthropological concepts. One of the problems that is being considered today in psychology, sociology, and anthropology is the clash in one socio-cultural space of different values, lifestyles and worldviews. Discussed in the context of the anthropology of contemporary, the forms of socialization are united by a transdisciplinary approach, which, integrating these studies at the general scientific level of methodology, at the specific scientific level, reveals the antinomies of simplicity and complexity, commonality and differences, constancy and change, structures and processes. Normative diversity is introduced as a construct that reflects the idea of positive socialization in modern society, characterized by increased sociocultural mobility, creolization (cultural mixing) phenomena, and diversification of life strategies.

On a sample of siblings at the age of early adulthood, the structure of links between the locus of control and other psychological characteristics is considered. The sample included 106 pairs of siblings (212 respondents in total) with an age difference of no more than 5 years; the average age of the older sibling is 24.51 ± 4.56, the younger one is 21.73 ± 4.17 full years. Each member of the sibling couple completed 5 questionnaires: Level of Subjective Control, Short Big Five Portrait Inventory, Short Version of the Uncertainty Tolerance Inventory, Short Version of the Sensation Seeking Inventory, and the Dirty Dozen Inventory. The data obtained during the study are studied in two subgroups - older and younger siblings of each pair. It was revealed that, on average, older and younger siblings do not differ from each other in the localization of control over significant events for themselves, both in life in general and in particular specific situations (health status, achievements, failures, family, workplace and interpersonal relationships). At the same time, the study of the structure of the links between the level of subjective control and other psychological characteristics in the groups of older and younger reveals a number of differences.

The problem of psychological safety in the modern school is highly relevant at the moment, but a broad interpretation of this category requires specification. The article sets the task of identifying teachers’ attitudes towards interaction with students and teachers’ ideas about the school as a whole. This research task allows us to address the issue of psychological aspects of the safety of the educational environment from a new angle. The study is exploratory in nature. The respondents were 77 secondary school teachers with an average teaching experience of 24.2 years. The results showed that the respondents, first of all, are unanimous in their ideas about the school as an important institution of education and upbringing, with a high goal and achievement orientation, formalization and structure. Teachers are focused on maintaining a favorable climate in the children’s environment, removing conflict, supporting psychological comfort, supporting children in their endeavors and self-expression. However, the emotional side of the relationship does not occupy a dominant position, although empathy for students, trust in communicating with them, is recognized as an important component of creating a friendly atmosphere.

The results of a study of professional burnout among employees of a commercial organization are presented in the article. The study involved employees of a pharmaceutical company (N=101) with different experience, higher education, aged 22 to 60 years (SD=8.62), men 21.8%, women 78.2%. Socio-demographic variables (gender, age), characteristics of professional activity (length of service, position, predominant content of work tasks, compliance of responsibilities with education) are not associated with the severity of burnout in this sample. The traits of the “dark triad” “Machiavellianism” and “psychopathy” are significantly higher in the group of more burned-out employees; the indicators on the “narcissism” scale did not show significant differences. Indicators of “proactive overcoming”, “reflexive overcoming”, and “strategic planning” turned out to be significantly higher in less burned-out employees, and the intensity of psychological defenses did not differ. Proactive coping strategies are associated with burnout in all respondents, psychopathy is associated with burnout in respondents with moderate burnout severity, and personality defense mechanisms are associated with burnout in respondents with high burnout severity. The burnout of the pharmaceutical company employees who took part in this study turned out to be associated with the psychological characteristics of the respondents, and not the characteristics of the organization of their professional activities. In particular, Machiavellianism, psychopathy, proactive coping, and psychological defenses were associated with burnout, and the connections of these psychological characteristics differ among respondents with different burnout severity. The results of the study indicate the expediency of studying the psychological factors of burnout, taking into account the severity and phase of burnout.
The Influence Of Ph And Concentration Of Phosphonate Inhibitor - Tests On Change Of Barium Sulfate Scale Morphology By Using Scanning Electron Microscope
Authors: Makmur Tjuwati
Published: March 2022

Water injection is often used to keep maintaining reservoir pressure. Injected water (high in sulphate) mixes with formation water (high in barium) leading to the deposition of barium sulfate scale in the near wellbore, reservoir, production tubulars and topside equipment. Barium sulfate scale is unique scale deposit and the least soluble of the scales. The deposition of oil field scale is a potentially damaging problem which reduces fluid flow resulting in a decline in oil production. The best approach to solving the problems of scale formation is to prevent or inhibit deposition and this is more effective than scale removal. The use of scale inhibitor can be effective method for preventing scalealthough their effectiveness is controlled by experimental conditions. Therefore, it is very important to know factors that influence barium sulfate scale. The maintopic of this paper is “The Influence of pH and Concentration of Inhibitor Solution - Tests on Change of Barium Sulfate Scale Morphology by Using Scanning Electron Microscope”. Hopefully, the results of laboratory test presented this paper give useful and valuable information not only for LEMIGAS, but also for oil industry, chemical manufacturers and universities, then other institutions.
Development Of Waterflood Profile Modification Using Brightwater Technology

Water flooding, in many mature fields is facing a common problem of low sweep efficiency in the late production period. The breakthrough of injection water is very early when high permeability streaks or thief zones exist in the formation, and resulted in excessive water production. Two kind of technologies commonly are used to modify the permeability streak i.e. MPM (Microbial Profile Modification), and polymer gel with cross linkers material. A new technology which is called Bright Water has been intensively studied. Bright Water is capable of in-depth placement into high permeability streaks in the reservoir. To improve the water flood sweep efficiency, studies of examination a fluid injection design have been evaluated. The objective of this study is to set-up core flooding tests and to determine the effective- ness of the Bright Water to reduce the permeability, and also include optimization of Bright Water formulation, resistance factor determination, and gelling time evaluation.
The advantages of electric vehicles that their current consumers can highlight in order to inspire other consumers to choose a sustainable option

Electric vehicles have a number of advantages that help people live a more sustainable lifestyle, but the role of their users in encouraging others to embrace them has not been studied. Recent studies have identified three major motivations for people to embrace electric vehicles as a sustainable mode of transportation: personal benefits, moral standards, and hedonic. In this study, we focused on the key benefits of electric vehicles to see what motivations they elicit among car buyers, so that current owners of electric vehicles could highlight them while encouraging other groups of consumers to select electric cars over conventional ones. We noticed that reducing GHG emissions and ownership costs motivate at least two of the key motivations, increasing the likelihood of persuading people to accept EVs to join the consumers with responsible lifestyles.
