Baru tree (Dipteryx alata) is an arboreal, fruitful plant native to the Cerrado Biome with an important socioeconomic impact. This study aimed to identify and characterize new microsatellite loci for D. alata. From the development of a genomic library enriched in microsatellites, ten pairs of primers were synthesized. Of these, seven were polymorphic, providing a total of 49 alleles, with an average of 5 to 5.57 alleles per locus. A significant content of polymorphic information was obtained, as indicated by the average expected heterozygosity (uHE), with a total average of 0.58 to 0.65 per locus. The average value of the observed heterozygosity (Ho) was also high, with a total average of 0.73 to 0.85 per locus. Some of the loci are in linkage disequilibrium, such as (Dalat G6 with Dalat B3, H3 and B4), in addition to (Dalat B4 with B5). The estimate of the combined loci for the probability of paternity exclusion obtained an average value of 1.00 for all loci, and the average combined probability of identity, the values were (1.210^−5) to (4.410^−6). The results obtained here show that the markers developed for D. alata are informative and suitable for studies on genetic diversity and population structure, aiming at the conservation and management of the species.

To assess the consistency of the model parameters the cumulative sum of recursive residuals test and the cumulative sum of recursive residuals squares tests are used.Additionally, cointegration equations such as the Fully Modified Ordinary Least Square Dynamic Ordinary Least Squares, and Canonical Cointegration Regression are applied to check the long-run elasticities in the concerned relationship.
Prioritizing Post Disaster Recovery Needs: Academicians versus Practitioners
Authors: Nejat Ali , Moradi Saeed
Published: June 2021

Effective knowledge transfer between researchers and practitioners within the hazards and disaster domain has long been a challenging task. The diversity of hazard researchers and practitioners, as well as the high stakes of applying research outcomes, have contributed to the issue. This research aims to explore potential discrepancies between researchers and practitioners’ perspectives regarding post-disaster recovery needs. To achieve the objective of this research, a survey was developed and conducted during the 2019 Natural Hazards Workshop in Broomfield, Colorado, which is host to individuals from various career backgrounds, including researchers, practitioners, policymakers, students, etc. Exploratory factor analysis and elastic net regression were used to provide a link between individuals’ awareness of these challenges and their personal attributes. Results highlighted the discrepancies between researchers and practitioners in how they perceive and prioritize recovery needs. Results from this research can be used to bridge the existing perception gap with the goal of devising policies that can improve recovery by addressing the needs more realistically.

SARS-CoV-2 variants of concern (VOCs) have emerged worldwide, with implications on the spread of the pandemic. Characterizing the cross-reactivity of antibodies against these VOCs is necessary to understand the humoral response of non-hospitalized individuals previously infected with SARS-CoV-2, a population that remains understudied. Thirty-two SARS-CoV-2-positive (PCR-confirmed) and non-hospitalized Canadian adults were enrolled 14-21 days post-diagnosis in 2020, before the emergence of the B.1.351 VOC (also known as Beta). Sera were collected 4 and 16 weeks post-diagnosis. Antibody levels and pseudo-neutralization of the ectodomain of SARS-CoV-2 spike protein/human ACE-2 receptor interaction were analyzed with native and B.1.351 variant spike proteins. Despite a lower response observed for the variant spike protein, we report evidence of a sustained humoral response against native and B.1.351 variant spike protein among non-hospitalized Canadian adults. Furthermore, this response inhibited the interaction between the spike protein variant of concern and ACE-2 receptor for ≥16 weeks post-diagnosis.

Das Individuum muss in der Risikogesellschaft Lebensentscheidungen treffen und damit verbundene Risiken eigenverantwortlich tragen (Beck 1986). Zudem sind Optimierungsimperative allgegenwärtig, die als Disziplinierungen gesellschaftlich produktiv und für das Individuum zugleich einschränkend sein können (Foucault 1976, 265). Durch technischen Fortschritt gleichen diese heute mehr denn je «ultra-schnellen Kontrollformen mit freiheitlichem Aussehen» (Deleuze 1993, 255). Besonders sichtbar werden sie als Self-Tracking-Apps. Sie versprechen z. B. eine Steigerung der körperlichen Fitness oder der individuellen Leistungsfähigkeit. Jedoch sind etwa durch Datenmissbrauch, utopische Zielvorstellungen und Verdatung auch zahlreiche Risiken mit der Nutzung verbunden (Selke 2016). In unserem Beitrag werden wir die unterschiedlichen Facetten des Phänomens auf Basis einer qualitativen Studie mit Studierenden diskutieren. Wir arbeiten in einer zweiteiligen Analyse heraus, wie sich verändernde Selbst-/Weltbezüge im Spannungsfeld zwischen Kontrolle und Selbstermächtigung konstituieren. Zur Verdeutlichung rekonstruieren wir an einem Beispiel, wie sich das konturierte Spannungsfeld in die Self-Tracking-App Time Reduction einschreibt, und zeigen an Interviewmaterialien, wie sich ein Student zu diesem in Beziehung setzt.
Geophysical search for fragments of the Sterlitamak meteorite
Authors:   Bulashevich Institute of Geophysics of the Ural Branch of RAS, Arkadiy Vasil’evich OVCHARENKO
Published: June 2021

Relevance is determined by the fact that meteorites are of great importance for the direct study of the substance of the Universe, therefore, when new meteorites fall, maximum efforts are made to detect them and study the conditions of the fall. The purpose of the work is to further study the meteorite crater and search for large fragments of the Sterlitamak meteorite not found at the first stage of study using geophysical methods. The story of the fall and searches for the main fragment of the Sterlitamak meteorite, which fell on August 17, 1990 at 23 h 25 min, on the field of the Sterlitamak state farm is described. When it fell, a crater with a diameter of 10 m and a depth of 4 m was formed. The fall was accompanied by a bright glow and thunderous rumbles. A glow was observed over the crater in the dark. A high-speed searching for the meteorite was organized by collecting meteorite debris around the crater. At the same time, a mine detector was used. The crater was excavated with an excavator to a depth of 18–20 m. Fragments weighing 6.6; 3.06; 0.875; 0.363 kg were found. A year later, the main body weighing 315 kg was accidentally found in the dumps. Chemical analysis of the substance showed that it is an iron-nickel meteorite, 98% of the thickness are the minerals kamacite, tenite and schreibersite. Results. In 2014–2015, the authors carried out magnetic surveying around the crater and on the ice of the lake, which was formed at the excavation site, in order to search for fragments of the meteorite, which were probably missed at the initial stage. Maps of the magnetic field and terrain of the crater are given. Magnetic anomalies are identified, which are presumably associated with new fragments of the meteorite. The probable depths of the meteorite fragments are 2–4 m. In-depth sections of the magnetization for these anomalies obtained by the method of magnetic tomography, are given, as well as the results of a surface survey of the dump area using a metal detector. Weakly magnetic samples were found containing sprayed metal and metal balls with a diameter of 0.5–1.0 mm. These samples originally formed a zone of impact metamorphism, which was destroyed by excavation operations. It is shown that the territory is promising for searching for new large fragments of the meteorite and studying the processes of impact metamorphism. It is planned to further study the crater by means of electrical exploration and GPR sounding.

Relevance of the study. In the current context, there are quite negative trends in the coal industry: instability of the situation in the coal markets and increased competition, which creates risks of financial instability of enterprises. In these conditions, it is important to develop a financial strategy aimed at fulfilling promising production tasks. The purpose of the study is to substantiate the financial strategy of large coal producers. Research methods – scientific generalization, logical analysis, methods of comparison and analogies. Results of the study. The key points of the financial strategy have been identified: the goal of the effective development of a coal producer; time – long-term benchmarks; mechanisms – financing; directions – the implementation of financial activities; conditions – external and internal environment. The development of a financial strategy is based on a system of financial ratios used to form an acceptable structure of working capital. Calculation formulas are proposed to determine the required amount of cash, short-term financial investments, accounts receivable and the amount of stock in the composition of working capital. The quantitative values of these indicators that are acceptable from the point of view of the financial strategy have been determined: not less than 25%, not more than 25%, not more than 50%, respectively. The set of financial ratios for the formation of an acceptable ratio of own and borrowed funds, their calculation formulas and recommended values are recommended. The values of the coefficient Kз/с of the ratio of borrowed and own funds, which determines the possibility of using borrowed funds, are given. In direct connection with Кз/с, the autonomy coefficient is considered and its reasonable values are justified. Conclusions. The specified conditions for the formation of a financial strategy are primarily related to large coal producers, where there are opportunities for revenue growth and a reduction in the duration of the production cycle. The proposed acceptable values of financial ratios will make it possible to achieve sustainable financial independence of enterprises and ensure their effective development.
Stock price reactions to information about top managers
Authors: Cao Mai Phuong Lai
Published: June 2021

This article uses an event study to investigate the response of a bank’s stock price to information related to these banks’ top managers. In the first event, the Vice Chairman of the founding board of Asia Commercial Bank (ACB) was arrested and the Chief Executive Officer (CEO) of this bank was summoned by the police for questioning. The second event related to the immediate resignation of the Chairman of the Board of Directors of Sacombank (STB) after he received a summons from the investigating police agency. Both of these events happened in Vietnam. The research results showed that unanticipated events (the first event) caused the share prices of both banks to react more strongly, and the impact time was longer than the second event. The first event resulted in the cumulative abnormal returns of ACB and STB being –23.6% and –9.1%. The second event has been found to be directly related to STB, but does not significantly affect this stock, but has a significant effect on the abnormal return of ACB (AR (1) = –4.6%). Asymmetric information, inattention and investor fear of event-related losses may explain this phenomenon.

Published: June 2021

There are many problems related to audit quality, which are often associated with audit failures. Internal government auditors in Indonesia also have issues with audit quality. Therefore, this study aims to present empirical evidence on the relationship between independence, competence, motivation, and audit quality. It will also determine the moderating effect of time budget pressure on the relationship between factors and audit quality. Data of this study were collected through a google form, in which 57 questionnaires were sent to internal auditors of government within the Principal Inspectorate of Indonesia’s Supreme Audit Institution for at least two years. The study adopted a quantitative approach using purposive sampling. Data were analyzed using Structural Equation Modeling (SEM) with PLS version 3.0. The result findings of this study revealed that competence and motivation have a significantly positive effect on the quality of audit while independence does not. Time budget pressure does not significantly moderate such a relationship. In addition, these results have several significant implications for internal auditors as an object of consideration and evaluation relating to audits in the government sector, and information for government internal auditors to improve and maintain the quality of audit.

Authors:   Assistant Professor of English, Institute of Honors and Integrated Studies, Kurukshetra University Kurukshetra, Haryana, India., Pal Virender
Published: June 2021

Chigozie Obioma is a novelist of Nigerian origin who has published two novels so far. He has been hailed as an ‘heir to Chinua Achebe’ the master African novelist. The comparison of Obioma with Achebe is obvious because both of them belong to the same tribe, but what is more important is that Obioma seems to carry from the point where Achebe left. In his debut novel The Fishermen, Obioma foregrounds the problems that plague postcolonial Nigeria. In the novel, he confirms that whatever Achebe prophesied about the future of Nigeria has come true. Like his illustrious predecessor, he is critical of colonial institutions that have decimated the national culture of Nigeria. The paper is a study of Obioma’s novel The Fishermen.

Drawing on Amitav Ghosh’s novel Gun Island (2019) together with his nonfictional The Great Derangement (2016), the article strives to present that while advancing endless desires, human-centric culture and the idea of ‘good life’ drive climate change and environmental deterioration. It seeks to enumerate the devastating consequences of changing climatic conditions and degenerating ecosystems and their cumulative impacts on the humankind and non-human world. It aims to locate how human life at the margins has been affected by these cataclysmic consequences through analysing Ghosh’s Gun Island. It attempts to show that human interventions had significantly fuelled the global climate crisis in the seventeenth century, decoding the myth of Bonduki Sadagar that Ghosh identifies in Gun Island.
Conversations through Web 2.0 tools: Nurturing 21st century Values in the ESL Classroom
Authors:   Department for Training and Development, School of English Language Education, The English and Foreign Languages University, Hyderabad, India., Jose Kshema
Published: June 2021

21st century skills framework proposed by the World Economic Forum (2015) suggests that the development of foundational literacies, competencies and character qualities in students can help them function as responsible and productive global citizens. However, most educational systems focus only on developing foundational literacies like reading and writing, numeracy, scientific literacy, etc. This paper describes an exploratory research conducted to investigate how the 21st century ESL teacher can nurture the development of competencies and character qualities through language development tasks delivered using digital tools. The paper is based on the premise that since character qualities are both social and individualistic in nature, they are ideally delivered through collaborative events and acquired best through self-reflection. Reporting from an ESL teacher’s perspective, the paper elucidates how participating in the communication, collaboration, critical thinking and creativity activities mediated through web 2.0 tools can facilitate the acquisition of character qualities like curiosity, persistence, adaptability, social and cultural awareness, etc. It was found that certain features of web 2.0 tools like participatory environments, asynchronicity and ease of use for creating content offered students multiple opportunities for meaningful, sustained and reflective conversations. Using observational data, the researcher identifies the acquisition of character qualities and the development of competencies in students through these conversations.
Passive defense in water resources
Authors: Alashti Habib Akbri , Bozorg-Haddad Omid , Bocchiola Daniele
Published: June 2021

Today, both freshwater and wastewater treatment plants are tremendously important for humans and their health. Additionally, water and water systems are sensitive because of their impacts on economic performance. At the same time, economic and population growth, and rising standards of living lead to increased water demand, and freshwater can be scarcely available. The increasing importance of water in modern society has increased the sensitivity and vulnerability of water systems, and the concern about the consequences of any disruption to them, leading to the growing importance of passive defense. Passive defense plays an important role in identifying vulnerability and likely threats, making emergency response plans, and preventing and responding to such threats. Water infrastructures could be physically destroyed, cyber-attacked, or contaminated through the introduction of chemical and biological agents. These threats can have different origins. Some of them may be unintentional and even natural disasters, while others may be due to terrorist attacks, or to regional conflicts and disputes over local water resources. In this chapter, a review of the types of threats pending on water systems is presented, together with a short history of these threats. The vulnerability of water systems is investigated, and approaches to prevent and respond to them is reported.
Citizen science

Published: June 2021

Today, developments in science and technology have made people more sensitive to their surroundings, as well as to the problems and challenges that surround them or threaten their lives in the future. This change in the way people look at the problems and big challenges of life today has led them to increasingly use science and technology. Scientific and technological progress has enabled humans to solve challenges that were once thought insoluble. These problems often involve three main limiting factors: cost, time and the need to collect lots of data. Today, in most countries, a solution called ‘citizen science’ is used to solve these big problems and projects. Indeed, the main foundation of citizen science is that it is used to conduct extensive experiments by ‘citizen scientists’ in areas such as sampling and other time-consuming and costly activities. This chapter explains how, after an initial research plan is presented and has been evaluated, the decision is made by scientists whether or not to employ citizen scientists. In the next stages, described below, scientists attract volunteer citizens, then carefully plan the details of the subject and the relevant training and education needed to carry out the various stages of the research proposed. After completing these training courses, citizens scientists enter the stage of conducting experiments and collecting the required data. Finally, scientists analyze the information collected by scientists. The chapter describes this complete process, and supplies suitable examples.
ADR in Journals: Are They Translated into Regulatory Frameworks?
Authors: Kolupoti Annapurna , Chakraborty Ananya , Shahistha K.
Published: June 2021

Introduction:

An adverse drug reaction case report refers to a scientific publication that
is written by a health care professional who suspects a casual relationship between a drug and an
adverse drug reaction (ADR). ADR case reports help to identify potential risks associated with the
use of drug. Most of the case reports do not mention about reporting the ADR to regulatory authorities.
With this objective, the aim of this study was to analyze the number of Adverse Drug Reactions
(ADR) published as case reports (PubMed indexed journals) from January 2018 to June 2019,
and observe if they are translated in regulatory frameworks like Vigibase, and package inserts.

Materials And Methods:

321 ADRs were obtained with the keywords “Adverse Drug Reaction”.
Out of those, 158 were independently extracted by two investigators, observed and categorized according
to classes of the drugs, geographic location, severity, hospitalization, Completeness of
ADR, whether reported to the regulatory authority (Vigibase), or listed in the package insert. Literature
review articles were excluded.

Results:

Out of the 158 ADRs, antibiotics accounted for 12.65%, CNS drugs and monoclonal antibodies11.39%,
anticancer drugs 9.49%, CVS drugs 4.43%, anti-viral 3.79%, others 45.56%, respectively.
According to geographic region, 26 ADRs published were from USA, Australia 4, Italy 3,
India 17, Turkey 9, Singapore and UK 1, China 20, Denmark and Canada 2, Japan 10, France 9,
Austria 1, Korea 5, South America 3, Switzerland 2, respectively. Depending upon the severity,
causality assessment was done only for 45 ADRs, and not done for 113 ADRs. 41.13% patients
(from 65 case reports) were hospitalized. Among the 158 ADRs, 14 ADRs were not found in Vigibase.
32 ADRs were not mentioned in the Drug package inserts. When categorized according to
the completeness of case reports, weight accounted for1.89%, lab values and procedure for diagnosis,
96.8%, risk factors, 95.56%, prior exposure, 88.60%, Post ADR status, 60.12%, start-stop medication,
route of administration, first dose, last dose, duration of illness accounted for 100%, respectively.

Conclusion:

Depending upon our observation, we have noticed that there is deficiency in reporting
of suspected ADRs to regulatory authorities. Reporting can be included as mandatory criteria for
ADR case reports. Also, there is an increased need to aware various healthcare workers for reporting
ADR.

Proper regulation of the innate immune response to bone biomaterials after implantation is pivotal for successful bone healing. Pro-inflammatory M1 and anti-inflammatory M2 macrophages are known to have an important role in regulating the healing response to biomaterials. Materials with defined structural and topographical features have recently been found to favourably modulate the innate immune response, leading to improved healing outcomes. Calcium phosphate bone grafts with submicron-sized needle-shaped surface features have been shown to trigger a pro-healing response through upregulation of M2 polarised macrophages, leading to accelerated and enhanced bone regeneration. The present review describes the recent research on these and other materials, all the way from benchtop to the clinic, including in vitro and in vivo fundamental studies, evaluation in clinically relevant spinal fusion models and clinical validation in a case series of 77 patients with posterolateral and/or interbody fusion in the lumbar and cervical spine. This research demonstrates the feasibility of enhancing biomaterial-directed bone formation by modulating the innate immune response through topographic surface features.

Real Time Night Vision Surveillance using Improved Dark Channel Prior
Authors: Bhushanam M. V. Naga
Published: June 2021

Videos taken under low lighting conditions usually result in severe loss of visibility and contrast and are uncomfortable for observation and analysis. Night vision cameras that cater to the needs are expensive and less versatile. To be cost effective and extract maximum information from videos taken in low lit conditions, video enhancing techniques must be used. Though there are many night vision enhancement techniques available in literature, this paper particularly emphasizes about Improved Dark Channel Prior algorithm and its results. This approach suits well for real time night video enhancement. It has been found that a pixel-wise inversion of a night video appears very similar to the video obtained during foggy days. The same idea of haze removal approach is used to boost the visual quality of night videos. An improved dark channel prior model is presented that is integrated with Gaussian Pyramid operators for local smoothing. The experimental results show that the proposed method can boost the perceptual quality of detailing in night videos.
Implementation of Sparse Techniques for MIMO Channel Estimation
Authors: Ramith S.
Published: June 2021

Channel estimation plays a very important role on the performance of wireless communication systems.Channel estimation can be carried out in different ways: with or without the help of a parametric model, using frequency and/or time correlation properties in the wireless channel, blind methods or those based on training pilots, adaptive or non-adaptive methods. As more antennas are added to Multiple Input Multiple Output (MIMO) system more computational resources and power are required. There is a need to address this problem of the overhead in training symbol based models for channel estimation. Compressed Sensing (CS) algorithms are beneficial in addressing these limitations in the system to increase the spectral efficiency can help free up resources and prevent additional taxing on the hardware. Compressed sensing the pilot symbols by using CS algorithms like OMP, SP, and CoSaMP algorithms. The channel coefficients are obtained through LS, MMSE and LMS techniques. Then, a very small amount of frequency-domain orthogonal pilots are used for the accurate channel estimation.The traditional algorithms like LS , MMSE and LMS combined with CS algorithms have better performance at low SNRs compared to conventional techniques alone in terms of computational time complexity and Normalised Mean Square Error(NMSE) performance. There is a halving of pilot symbols used for training by using the CS algorithm. MSE performance is increased with increase in sparsity level. CoSaMP performs better than SP and OMP at low SNRs. With increase in sparsity level after 50K, the performance of SP is comparable to that of CoSaMP. OMP is simple to implement but MSE performance is less and computational time is more compared to SP and CoSaMP.
Multi Class Data Classification to Improve Accuracy in Sentiment Analysis using Machine Learning
Authors: Vishnu Daram
Published: June 2021

Sentiment analysis means classifying a text into different emotional classes. These days most of the sentiment analysis techniques divide the text into either binary or ternary classification in this paper we are classifying the movie reviews into 5 classes. Multi class sentiment analysis is a technique which can be used to know the exact sentiment of a review not just polarity of a given textual statement from positive to negative. So that one can know the precise sentiment of a review . Multi class sentiment analysis has always been a challenging task as natural languages are difficult to represent mathematically. The number of features are also generally large which requires huge computational power so to reduce the number of features we will use parts-of-speech tagging using textblob to extract the important features. Sentiment analysis is done using machine learning, where it requires training data and testing data to train a model. Various kinds of models are trained and tested at last one model is selected based on its accuracy and confusion matrix. It is important to analyze the reviews in textual form because large amount of reviews is present all over the web. Analyzing textual reviews can help the firms that are trying to find out the response of their products in the market. In this paper sentiment analysis is demonstrated by analyzing the movie reviews, reviews are taken from IMDB website.

Published: June 2021

The project we designed is used to develop a distance measurement system using ultrasonic waves and interfaced with Arduino UNO. We know that the human audible range is from 20hz to 20khz. We can use these frequency range waves through ultrasonic sensor HC-SR04. The main advantages of this sensor are when this sensor is interfaced with Arduino which is a control system and a sensing system, a proper calculation of the distance measurement can be done by using different types of new techniques. As huge amounts are spent on hundreds of inflexible circuit boards, the Arduino board will allow the business to bring many more unique devices. These distance measurement systems are mostly used as range meters and as proximity detectors in the different types of industries. The hardware part of the ultrasonic sensor is interfaced with the Arduino Uno board. This type of measuring distance is an efficient way to measure even small distances accurately. The distance of an object from the sensor is measured by using an ultrasonic sensor. After knowing the speed of the sound wave the distance of an object can be calculated.

Rotary draw bending an ongoing process. It’s an at-hand service proffered within the current market. However, each draw bender features a divergent mechanism with its pros and cons, thanks to its main advantages; the rotary draw bender was selected. Pipe bending machines have progressed many enhancements and augmentations over the amount. The sort of pipe bending plays a critical role in industries, instruments, and transporting of fluids. The first concern is that the required bend angle that this pipe will bend on. The following report will include an outline of the accessibility of this machine. The crucial variables that ought to be accounted for within the pipe bending is bend radius bend angle, pipe diameter, and thickness. The concept of press bending is employed to hold out the operation; thus, the specified force is administered with the help of a hydraulic jack. Also, other important variables are accounted for, like the bending force, bending torque, simulation outcomes about the work piece analysis, and eventually the machine design. Moreover, a prototype that satisfies the specified constraints is manufactured and assembled. Being a manual bending machine means no use of electricity is required, leading to no power consumption. Additionally, this machine is favorable, feasible, affordable, low maintenance, and higher accuracy.
Post Covid-19: Outbreak of Mucormycosis
Authors: Kawale Ajit
Published: June 2021

The main aim of Corona is transmission of disease from person to person, and it had also been declared as a global pandemic which has caused disaster in the respiratory system of more than five million people and killed more than half a billion people across the world. Patients surviving from Covid-19 have lower immunosuppressive CD4+ T and CD8+ T Cells. And most of the patients are in severe need of mechanical ventilation. This is the reason for a longer stay in hospital for a particular patient. Gradually, these patients have been discovered to develop fungal co-infection. This infection is deadly leading to loss of hearing, loss of sight and eventually death. The fungal infection is referred to as Mucormycosis, the black fungus. The causative agent for this infection is Mucormycotina which is a member of Mucorales. Mucormycotina usually habitats in soil and decaying organic matter. The infection of Mucormycotina is associated with a wide range of human diseases including arthritis, gastritis, renal disorders and pulmonary diseases. This infection is closely associated with the mucous layer of skin, precisely cutaneous layer. This infection is present in the nasal and upper respiratory tract. In the lower respiratory tract these infections are difficult to diagnose and treat due to the lack of precise methods. It was found those neutroponia patients are more prone to this infection. This is caused by extensive use of chemotherapy resulting in impaired immunity. In recent times, in the case of pulmonary Mucormycosis, necrotizing pneumonia is a major symptom. A combination of antifungal and antimicrobial agents is being used for a higher clinical recovery in the Mucormycosis case.

Efficient Local Secret Sharing for Distributed Blockchain Systems
Authors: Latha G.
Published: June 2021

Blockchain system store transaction data in the form of a distributed database where each peer is to maintain an identical copy. Blockchain systems resemble repetition codes, incurring high storage cost. Recently, distributed storage blockchain (DSB) systems have been proposed to improve storage efficiency by incorporating secret sharing, private key encryption, and information dispersal algorithms. However, the DSB results in significant communication cost when peer failures occur due to denial of service attacks. In this project, we propose a new DSB approach based on a local secret sharing (LSS) scheme with a hierarchical secret structure of one global secret node and several local secret nodes. The proposed DSB approach with LSS improves the storage and recovery communication costs.

Published: June 2021

The possibilities of creating solar reusable megawatt-class interorbital tugs are analyzing. A comparison of solar and nuclear power plants is given, and the advantages of using solar systems are justified. On the basis of a comparative analysis of analogues, such as solar sails, solar reflectors for illumination from Earth's orbit, solar panels of space power plants, the advantages of using frameless centrifugal solar panels in comparison with frame analogues are justified. It is indicated that the design and development, as well as the production and technological reserve and test base are sufficient for the creation of a solar power plant in the Russian Federation. The authors point out the prospect of using oxygen-hydrogen fuels obtained by electrolysis of water in space, which greatly increase the speed of transport operations, and the need to create electro-magnetic accelerators for launching from Earth with large cargo flows. The design evaluation of the parameters of centrifugal solar panels with a capacity of 1 and 5 MW is given. The necessary funding for the work was estimated.
National Identity and the Associative-Verbal Network: on a Hypothesis of Yu.N. Karaulov
Authors: Ufimtseva Natalya V. , Balyasnikova Olga V.
Published: June 2021

The article presents the results of the study dedicated to native speakers sites of memory associated with key images of the Russian national culture. The investigation was inspired by the work of French historians Les lieus de mmoire (1984), whose ideas Yuri Nikolayevich Karaulov applied to the Russian Associative Dictionary (RAD). The study was initiated with the hypothesis elaborated by Yu. N. Karaulov that the Russian national memory could be studied through associative dictionaries. This provision is based on the linguistic personality concept formulated by Yu. N. Karaulov that is regarded as a personality expressed in a language / text and can be reconstructed on the basis of linguistic means. The texts that a language personality produces reflect the peculiarities of a persons vision of the environment (worldview). The hypothesis is tested on associative fields of the toponym Moscow and the lexemes war and Sunday using the data of several associative dictionaries compiled from 1988 to the current moment, i.e., the Russian Associative Dictionary, and Yu. N. Karaulov among the authors, as well as a number of later dictionaries developed on the basis of massive associative experiments carried out in the regions of Russia. The content and structural analyses of the associative fields of stimuli Moscow , war , and Sunday show that the associative material largely reflects the discursive space of the language personality and its functioning in texts that reproduce these sites of memory in a precedent form. The latter, however, can be found as various types of reactions (predications) of a non-stereotyped nature. Therefore, the sought-for data exist in different guises, obviously depending on the historical time and the discursive experience of native speakers of a language/culture, as well as on the region of their residence. This study confirms the psycholinguistic concept of meaning (including the associative one) as a sociocultural phenomenon.
Values and Image of the Future of Generation Z: Systemic Particularity
Authors: Bubnova Irina A.
Published: June 2021

The article presents the results of a pilot experiment carried out within the framework of psycholinguistics and aimed identify the structure and content of the value system and the image of the future of generation Z. The relevance of such studies is substantiated; a complex of methods is described that allows: 1) reveal the specifics of the value system and the image of the future as its subsystem; 2) highlight the most significant signs of the studied phenomena in the group consciousness; 3) draw conclusions on the motives determining the hierarchy of values. The results of the analysis allow us conclude that at present there is a change in the connections between the elements of the structure of values, the core of which is the desire for life only by the interests of the inner circle of people and material prosperity. It is assumed that the experimentally recorded trend could be explained either by the ongoing gradual replacement of the values of traditional culture with the values of an individualistic society, or by the contradiction between social archetypes (according to K. Kasyanova), which determine the national type of linguistic personality (according to Yu.N. Karaulov) and the external form of the state as that society section, which quite rigidly tries to fix the main parameters of society of a certain state. It is argued that the lack of a clear understanding of the causes of what is going on, as well as the importance of the problem for society, determines the need for further research in this direction.
