The Effect of Wearing Masks for a Prolonged Duration on Concentration Level and Thinking Capability
Authors: Das Barun , Priyadarshini Anchita
Published: January 2022

The COVID-19 pandemic has forced us all to adapt to a new normal that requires a lot of contributions and sacrifices from one's side, keeping in sync with the restrictions put forth by the WHO. The newness is yet to become normal because there is undoubtedly a mass population of people struggling to overcome this challenge. The most affected ones are the children and the old citizens who show a greater vulnerability of contracting the virus. The basic shield we can put against it is our mask, which has become an integral part of our lives now and a great responsibility to prevent contact with the virus as well as its transmission. Since there is no alternative to masks, people of all age groups, starting from neonatal care to old age homes have to don them. On our personal experiences of donning masks for too long, we perceive that we face a constriction in the smooth processing of our thoughts and decisions while wearing a mask. It takes away a part of our concentration and hinders productivity and effectiveness in our daily work. We surveyed to examine how our brains and reflexes function on prolonged durations of wearing a mask, with participants from different age groups and work backgrounds. This survey's results had an interesting outcome and revealed that children and senior citizens find it the most difficult to process their thoughts and in giving clear answers. Though its reasons are still unclear, it raises a plethora of questions: do masks hamper oxygen flow to the brain and thus our thought processes? Do masks make us feel conscious about their presence and deprive our full concentration? Or is it just psychological that we cannot give our full attention when we have our masks on?
CRYPTOGRAPHIC TECHNIQUE FOR COMMUNICATION SYSTEM
Authors: Nabeel Mohd
Published: January 2022

In Today’s world Sensitive data is increasingly used in communication over the internet. Thus Security of data is the biggest concern of internet users. Best solution is use of some cryptography algorithm which encrypts data in some cipher and transfers it over the internet and again decrypted to original data. The field of cryptography deals with the procedure for conveying information securely. Cryptography includes a set of techniques for scrambling or disguising data so that it is available only to someone who can restore the data to its original form. Cryptography or communication by using secret code was used by the Egyptians some 4000 years ago. However, the science of cryptography was initiated by Arabs since 600s. Cryptography becomes vital in the twentieth century where it played a crucial role in the World War I and 2. This paper focuses on the analysis of the two types of key cryptography exists, based on the availability of the key publicly: Private key Cryptography, and Public Key Cryptography. Both the sender and the recipient share a key that must be kept private.

Problems and Solutions for Women Entrepreneurs in India
Authors: Pandey Shilpika
Published: January 2022

The fact is universally accepted that “if a woman grows, along with her grows the family, the society and the nation”. But this same family, society and nation act as a roadblock in the development of the status of women. Entrepreneurship is the most promising avenue for being financially and socially independent for the female population. In a developing country like India women constitute around 10% of total population of entrepreneurs. They have emerged as the rising stars of economies like India to bring wealth and prosperity. But still their valuable contributions are left ignored due to numerous societal and economical barriers. In this fast moving economy the government, NGOs, social scientists and international agencies have been showing interest in social upliftment of women entrepreneurs by initiating development programs and policies. On the other hand the obstacles created by society and women themselves have hindered their growth. Certain behavioral, social, institutional and government measures have been instrumental in empowering women entrepreneurship but their actual impact can be viewed only if these developmental policies are implemented eliminating societal and economic disparities. Keywords: Meaning of women entrepreneur, challenges of Indian women entrepreneurs, factors influencing women entrepreneurship, measures taken by the Indian government

Authors:   «OilGasScientificResearchProject» Institute, SOCAR, Baku, Azerbaijan, Aliyeva U. J.
Published: January 2022

Extensive exploratory investigations and borehole surveys have confirmed the high prospect of oil and gas potential of the Upper Cretaceous-Maikop deposits in numerous structures in the Ganja oil and gas region. The structures identified in the OGR have a complex structure and are also complicated by multidirectional fractures. Although the regularity of field formation has been clarified, an individual approach to prospecting and exploration operations at each block is necessary. It is necessary to direct prospecting and exploration operations to obtain direct geophysical parameters representing oil and gas potential in other blocks, taking into account the results of recent comprehensive geophysical surveys at the Gazanbulag-Chaily and Naftalan-Godakboz fields. Taking into account the available geophysical data and using appropriate geophysical complexes for predicting of oil and gas potential in anticlinal and non-anticlinal structures, determination of their boundaries and depths, elements of traps and stratigraphic affiliation is an effective way for further exploration of oil and gas. Keywords: seismic survey; refracted wave; gravity-magnetic survey; seismic and gravimetric anomaly; trap; oil and gas field; upper Cretaceous-Maikop.

Authors:   «OilGasScientificResearchProject» Institute, SOCAR, Baku, Azerbaijan, Huseynov R. M.
Published: January 2022

Oligocene-Miocene deposits, after the main oil-gas suit of Azerbaijan – the Productive Suit, are one of the most studied objects. This complex is classified as mature rocks and, according to the stratigraphic scale, is associated with Maykop, Chokrak, and diatom deposits. Therefore, studies of the conversion of organic substances to hydrocarbons under favourable sedimentation and thermobaric conditions are of great importance. In addition, the determination of hydrocarbon generation zones, the presence of appropriate paleotectonic and paleostructural conditions for their further migration and accumulation in traps are also important tasks requiring clarification. For this purpose, maps of the Maykop and Mid- and Upper Miocene sediments were constructed, models reflecting their paleostructural position by the end of the century of the productive stratum, and predicted paleotemperatures are indicated on the diagrams. As a result, it was found that the reducing-alkaline environment existing during sedimentation in the Maykop and Chokrak period was favourable for the conversion of organic substances into hydrocarbon. Keywords: Western Absheron; oligocene-miocene sediments; source rock; organic matter; oil window; vitrinite; geochemical condition; source of generation; migration; traps; paleostructure.

Microbial enhanced oil recovery is considered to be one of the most promising methods of stimulating formation, contributing to a higher level of oil production from long-term fields. The injection of bioreagents into a reservoir results in the creation of oil-displacing agents along with significant amount of gases, mainly carbon dioxide. In early, the authors failed to study the preparation of self-gasified biosystems and the implementation of the subcritical region (SR) under reservoir conditions. Gasified systems in the subcritical phase have better oil-displacing properties than non-gasified systems. Because, in a heterogeneous porous medium, the filtration profile of gasified liquids in the SR should be more uniform than for a degassed liquid. Based on experimental studies, the superior efficiency of oil displacement by gasified biosystems compared with degassed ones has been demonstrated. The possibility of efficient use of gasified hybrid biopolymer systems has been shown. Keywords: self-gasified; biosystem; microbial; subcritical region; slippage effect; enhanced oil recovery.

Published: January 2022

A modified Capacitive Resistive Model (CRM), with a non-linear Productivity Index (PI), has been suggested to evaluate efficiency of waterflooding in heterogeneous reservoirs. CRM model is based on continuity equation between production and injection, and has several additional advantages. The technique does not require sophisticated geological and hydrodynamics numerical simulation modeling, which would require expensive computing time and based on actual hydrodynamic data. The model adequately describes depletion process and can be used for production forecasting and waterflooding mechanism. Capacitance-resistance model with non-linear productivity index has been tested against numerical model as well as actual production data. Additionally, non-linear productivity index based CRM model was compared against the CRM model with linear productivity index function. The calculations algorithm does not require building static geological models and running dynamic simulations, nor it demands extensive computational resources and time, thanks to using production and injection history only, therefore it can be deployed easily. Keywords: waterflooding; capacitance-resistance model; non-linear productivity index; efficiency; monitoring; forecast.
Evaluation the volume of distribution of the injected water and the interaction between injection and production wells probabilistic and statistical methods
Authors:   Perm National Research Polytechnic University, Perm, Russian Federation, Ponomareva I. N.
Published: January 2022

The article describes the application of probabilistic-statistical methods for solving the urgent problem associated with determining the direction of movement of filtration flows. Today, the oil industry enterprises for these purposes use methods of hydrolistening and indicator research. These methods can most accurately assess the direction of movement of the filtration flows, but due to the high cost and duration of these studies in the Perm Krai fields are not often carried out. In this paper, we propose to study the interaction between production and injection wells by correlating the accumulated characteristics of their work. An analysis of the dynamics of the correlation coefficient between the accumulated values of water injection and liquid production performed in this way made it possible to establish qualitative indicators of the waterflooding system within the considered element of the development system. The obtained qualitative indicators of the waterflooding system demonstrate a high reliability of practical application, which is confirmed by the materials of tracer studies, as applied to the carbonate deposits of the Gagarinskoye field. Keywords: tracer studies; oil production; water injection; filtration flows; correlation coefficient; angular coefficient; carbonate reservoir.

The CMT-2 assessment, a computerized version of the original Contextual Memory Test (CMT), evaluates memory and meta-memory skills. Assessing these skills among adolescents’ is important for the development of interventions improving daily function. The objectives of this study were to evaluate (1) test re-test reliability, (2) internal consistency, (3) and concurrent validity with the Weekly Calendar Planning Activity (WCPA). Method: Twenty-two Israeli teenagers (12 boys and 10 girls) aged 12-18 years were recruited by convenience sampling. Participants completed the CMT-2 assessment, followed by the WCPA. Results: The reliability between raters was (r=0.94-0.96), indicating good results. Significant positive correlations were found between performance estimations of the immediate and delayed recall memory tasks (internal consistency) (r=0.519, p<0.05), as well as between the total number of strategies used and the total number of items remembered. Moreover, a significant positive correlation was found between the number of strategies and self-awareness (r=0.343, p<0.05). However, concurrent validity with the WCPA measure was not found. Conclusions: The findings of the study suggest that the CMT-2 measure can be used to assess memory and memory strategies in adolescents. Nonetheless, future research is required to adapt the CMT-2 to the Israeli population, and to determine concurrent validity with a different measure evaluating similar cognitive elements.

Background: Smartphones have the potential to foster independence for people facing functional cognition disabilities. According to the literature, this technology is seldom used as a rehabilitative tool given that OT’s are frequently are unfamiliar with these tools or feel insecure in their usage due to a lack of training. Needs Assessment Objectives: To examine the perception and the extent of use of smartphone applications, as a means of improving the independence of people dealing with functional cognitive disability. OTs and among those individuals dealing themselves with mental illness. Additionally, this study will examine OT’s interest in becoming more informed on this topic. Method: A needs assessment included conversations with policy makers in the Ministry of Health and OTs working in the field. An electronic survey was distributed on social media. Recipients of the surveys were OTs who work in mental health (N=58), the physical domain (N = 51), and people who were coping with mental health illness (N = 30). Results: A need for mobile applications as a means of functional cognitive intervention was found. Most of the patients (82.7%) responded that they could benefit from functional cognitive therapy using mobile technology, and 79.9% said that instructions given by professionals about its use were lacking. All mental health clinicians (100%), and 94.1% of those in the physical domain, responded that functional cognitive therapy using mobile technology would help their clients. Most mental health clinicians (89.5%) and 100% of those in the physical domain responded that they would like to gain more knowledge about mobile technology as a means of functional cognitive therapy. Conclusions: A project will be developed that will include a training booklet for functional cognitive therapy, accompanied by a lecture given by an expert OT in the field of technology. The goal of the project is to increase the use of mobile applications, as a means of improving the daily functioning of people who cope with functional cognition disabilities. Expected Clinical Implications: The training booklet and lecture will add to the knowledge about adapting and using mobile applications, as a functional cognitive tool, in the mental and physical fields. We expect that this knowledge will promote the use of applications in therapy, as well as improve the therapist's ability to use them.

Czechoslovakia and Latin America’s Guerrilla Insurgencies
Authors: Zourek Michal
Published: January 2022

An examination of the intelligence cooperation between Cuban and Czechoslovak secret services in returning Latin American nationals from Cuba to their home countries. It shows transfers via Czechoslovakia—known as Operation Manuel--were carried out at the Cuban leadership’s request after the Cuban Missile Crisis. Zooming in on the Czechoslovak government’s involvement in this operation, the chapter also shows that the Soviet Union's efforts to maintain strong political and economic ties with the Castro government were crucial. While the Czechoslovak secret service was relatively indifferent to Cuban efforts to promote its revolutionary model abroad and increasingly tried to cut off assistance in the context of rising complaints from Latin American governments, the Soviet Union insisted it should continue until Havana terminated the agreement. Czechoslovakia was therefore a center for communist organizations, a supplier of arms to subversive groups, and a crossroads in the transit of guerrillas. Drawing on archival documents, published memoirs, and personal interviews with “Manuelistas,” this chapter about Operation Manuel tells about Eastern Europe–Latin America relations and the Latin American Revolutionary Left’s global linkages.
The Influence of Latin America’s Revolutionary Left in Europe
Authors: Tristán Eduardo Rey
Published: January 2022

This chapter analyzes the diffusion of ideas that originated in Cuba and were developed by Latin America’s revolutionary groups during the sixties. Specifically, it examines the role played by key left-wing publishers in Europe: notably the Italian Giangiacomo Feltrinelli, France’s François Masperò, Germany’s Klaus Wagenbach, and Switzerland’s Nils Andersson. The chapter reflects on the dynamics of political-ideological diffusion within the third wave of international political violence, as well as on some of the actors who were key to this process taking place. The chapter is part of a broader reflection on the transnational dimensions of revolutionary violence in the 1960s and 1970s, and the links established between the two shores of the Atlantic.

Authors: Storck Carlos R. , Duarte-Figueiredo Fátima
Published: January 2022

The Fifth Generation (5G) cellular network is a good infrastructure option to connect vehicles through the Cellular-based Vehicle-to-Everything (C-V2X) technology. C-V2X aims to provide drivers comfort, road safety, autonomous steering for reliable connections and Advanced Driver Assistance Systems (ADAS). To 5G effectively provide C-V2X communications, there are many questions to answer and many problems to solve. One of them is the absence of an architecture that absorbs and characterizes the vehicles as special things in the Internet. The connectivity continuity guarantees after a handover is a huge problem because the vehicles have high mobility. It raises their handover occurrences as well as failed and unnecessary handovers. The thesis titled "A 5G Vehicle-to-Everything Ecosystem with Internet of Vehicles based Approaches" goals were the characterization of the IoV (Internet of Vehicles) the architecture supported by a 5G network on C-V2X communications, proposition of a 5G V2X ecosystem, the presentation of an user-centered Virtual Cells (V-Cells) selection probabilistic approach, a vehicular handover decision solution based on complex network metrics for 5G Ultra-Dense Network (UDN) and the validation of a structured model as a new 5G service provider facilitator. This thesis proposal and contributions include FiVH (5G Vehicular Handover) a solution that does the virtual cells selection and conformation and deals with the frequent handovers to provide many IoV services, such as on board video entertainment applications. The C-V2X applications can be efficiently supported by the 5G vehicle-to-everything ecosystem IoV communications.

Fog Computing-based Traffic Management Support forIntelligent Transportation Systems
Authors: Brennand Celso A. R. L. , Guidoni Daniel Ludovico , Villas Leandro Aparecido
Published: January 2022

Traffic in large urban centers contributes to problems ranging from decreasing the population's quality of life and security to increasing financial costs for people, cities, and companies. Considering the advance of communication, processing, and sensing technologies, Intelligent Transport Systems (ITS) have emerged as an alternative to mitigate these problems. The interoperability of ITS with new technologies, such as vehicular networks (VANETs) and Fog computing, make them more promising and effective. VANETs ensure that vehicles have the computing power and wireless communication capabilities providing a new range of security and entertainment services for drivers and passengers can be developed. However, these types of services, especially traffic management, demand a continuous analysis of vehicle ﬂow conditions on roads. Thereby, a huge network and processing resources are required making the development of ITS solutions more complex and difficult to scale. Fog computing is a decentralized computing infrastructure in which data, processing, storage, and applications are distributed at the network edge, thereby increasing the system's scalability. In the literature, traffic management systems do not adequately address the scalability problem, resulting in load balancing and response time problems. This doctoral thesis proposes a traffic management system based on the Fog computing paradigm to detect, classify, and control traffic congestion. The proposed system presents a distributed and scalable framework that reduces the aforementioned problems in relation to state of the art. Therefore, using Fog computing's distributed nature, the solution implements a probabilistic routing algorithm that balances traffic and avoids the problem of congestion displacement to other regions. Using the characteristics of Fog computing, a distributed methodology was developed based on regions that collect data and classify the roads concerning the traffic conditions shared by the vehicles. Finally, a set of communication algorithms/protocols was developed which, compared with other literature solutions, reduces packet loss and the number of messages transmitted. The proposed service was compared extensively with other solutions in the literature regarding traffic metrics, where the proposed system was able to reduce downtime by up to 70% and up to 49% of the planning time index. Considering communication metrics, the proposed service can reduce packet collision by up to 12% reaching 98% coverage of the scenario.

They can result in descensus of bladder, uterus, vagina or rectum and are often accompanied by incontinence. Symptoms like downward pressure, pain, incontinence or bladder voiding dysfunction develop slowly and are still highly taboo. Gynecology differentiates between descensus of the anterior, central and posterior compartment. A descensus in the anterior compartment causes a cystocele, with can either present as a pulsation cystocele or a traction cystocele. A descensus of the apical compartment leads to a uterine prolapse or vaginal stump descensus, while a descensus of the posterior compartment results in a recto- or enterocele. Urinary incontinence can be divided into stress and urge incontinence. The most important tool for the diagnosis of pelvic floor disorders is the clinical examination. Regarding the therapy of pelvic floor disorders, conservative therapy measures should first be offered. If these fail, an individually optimized surgical therapy should follow. The spectrum of surgical possibilities has expanded considerably in the last three decades. In particular, implanting alloplastic meshes has improved long-term stability. Finally, preventive measures also play a central role.
Becoming an Expert on Purpose: How Deliberate Practice Informs Teacher Effectiveness
Authors: G. Grant David
Published: January 2022

The call for teacher improvement has long been advocated in educational circles. Hargreaves & Fullan asserted it takes 8 years to reach the highest level. The important direct relationship of teacher effectiveness to student achievement was summarized by John Hattie. Many pathways to developing teacher effectiveness have been explored. A unique body of literature exploring expertise and it acquisition led to the articulation of deliberate practice theory with application in the domains of chess, music, medical training, and professional domains. Although a robust set of reviews have synthesized knowledge of deliberate practice in other domains, a comparable review could not be found in the field of education. Therefore, this chapter synthesizes the literature applying deliberate practice theory to the cultivation of teacher effectiveness.
Curcumin-Alginate Mixed Nanocomposite: An Evolving Therapy for Wound Healing
Authors: Sahu Sulata , C. Mallick Bairagi
Published: January 2022

A lot of advancements have taken place in the wound dressing materials and in wound healing process. Alginate based wound dressings materials are more preferable due to their biocompatibility and non-toxic unique biological characteristics. There’s always a need to increase the efficacy of alginates by combining with other biopolymers like chitosan, collagen and cellulose etc. However, the recent trend towards the natural and herbal bio-compounds are more likely attracting to develop alginate based wound dressing materials with higher efficiency, antimicrobial and anti-inflammatory potency. Out of many natural compounds tested, curcumin has shown high potency and more effectively used for wound healing purpose. Due to curcumin’s bio-medical properties it has been used as a vital ingredient combined with alginate and other biopolymers to prepare wound dressing materials. Based on the available literatures, this review chapter on alginate-curcumin nanocomposite will help the reader to develop better wound healing materials with evolutionary therapeutic applications.
Rheumatoid Arthritis and Periodontal Disease
Authors: B. Badiger Apoorva , M. Gowda Triveni
Published: January 2022

Rheumatoid arthritis (RA) is an immune-mediated inflammatory disease (IMID), chronic progressive causing inflammation in the joints and resulting in painful deformity and immobility, especially in the fingers, wrists, feet, and ankles. Periodontitis is defined as an inflammatory disease of supporting tissues of teeth caused by specific microorganisms or their groups, resulting in progressive destruction of the periodontal ligament and alveolar bone with periodontal pocket formation, clinical attachment loss, or both. Individuals manifesting both periodontitis and RA may suffer from a unifying underlying systemic dysregulation of the inflammatory response. In the past few years, increasing attention has been given to aspects of oral health in patients with rheumatoid arthritis, especially related to associations with periodontal disease. In this chapter we will be reviewing about the pathophysiology of RA and role of inflammation, periodontal disease: a gateway to RA, oral manifestations of RA, immunogenetics of RA and periodontitis, treatment implications for RA and periodontitis based on common pathophysiology.
Prophets, Land, and Law: Maori Holy Spirit Movements and the Domesday Book
Authors: Rosenfeld Jean E. ,   Academic Publishing
Published: January 2022

The experience of colonialization and Christianization among the Maori of Aotearoa (New Zealand), the Polynesians’ furthest settlement in the Southern Hemisphere, resulted in significant population decline of the Maori, land alienation, the rise of nativist revitalization movements, and British laws regarding land tenure that conformed to a Domesday Book tradition of conquest and social stratification. Nativist religious movements attempted to regain the land, reverse Maori population decline, and avoid the pathological consequences of aporia, a Greek word that signifies “without a bridge.” Three successive “Holy Spirit” movements arose to heal the breach between the old world of the Polynesians and the new world of British colonization and Christianization. Adherents assumed an identity as Israelites—the children of Shem—and challenged the Christian dominance of the Pakeha (European New Zealanders). From this culture clash came the Land Wars of the nineteenth century and the emergence of a new, biracial nation.
Why Environmental Philosophers Should Be "Buck-Passers" about Value
Authors: Stabell Espen Dyrnes ,   Center for Environmental Philosophy, The University of North Texas
Published: January 2022

The value of nature has been extensively debated in environmental ethics. There has been less discussion, however, about how one should understand the relation between this value and normativity, or reasons: if something in nature is seen as valuable, how should we understand the relation between this fact and claims about reasons to, for example, protect it or promote its existence? The “commonsense” view is that value gives rise to reasons. The buck-passing account of value (BPA), on the other hand, implies that for an entity or state of affairs in nature to be valuable just is for it to have properties (other than that of being valuable) that provide reasons to promote or have a pro-attitude towards it. BPA has been extensively debated, but has received little attention in environmental philosophy. In this paper, it is argued that the view suggests a “reasons first” approach to environmental ethics, and that it should be preferred to competing accounts of value in the context of environmental ethics.
How Identity Politics Objectifies People and Undermines Rational Agency
Authors: Shields Philip ,   Philosophy Documentation Center
Published: January 2022

In our contemporary society it is widely recognized that public discourse has become increasingly polemical and polarized, as claims to truth and justice are cynically dismissed as manipulative power plays. We argue first that this growth of power politics reflects the triumph of the objectifying stance of the social sciences, and the consequent loss of any distinction between legitimate and illegitimate power, and second that it is ad hominem to dismiss or accept people’s arguments simply because of their identity interests, their positionality, instead of considering the explicit meaning and validity of what they say. By adopting the objectifying perspective of the social sciences, identity theorists on the left and the right reduce “power” to coercion and fail to appreciate the power of persuasion, and the normative conditions that make rational agency possible. This tendency is ultimately contemptuous of human dignity because it undermines the rational agency and moral responsibility of everyone concerned, from the objectified human subjects to the objectifying theorists.
Adding new “C”s to our lexicon when considering the future of comparative education research: Complexity, care, and caution
Authors: Sider Steve
Published: January 2022

This article explores the question “What can inclusive comparative and international education research look like?” I situate my own experience in comparative research to consider three “Cs” for the future of comparative and international education: Complexity, care, and cautions. Complexity refers to the divisive and challenging global issues that exist and in which comparative education research takes place. As comparative and international education researchers, we need to practice an ethic of care in engaging in research in increasingly complex times. I conclude by providing three cautions for the future of research: transparency, positionality, and ethical relationality.
