This work aims to provide the scientific community with a comprehensive overview of the most challenging aspects of 5G mobile networks and present latest research on 5G+ promising techniques in 6G evolution. 5G mobile telecommunications technology meet the required ITU-R IMT-2020 standard to support an all Internet Protocol (IP) network for faster data rates, higher connection density, and much lower latency than previous generations. With the completion of the first full set of standards in the past 5 years, the initial commercial deployment of 5G mobile networks has begun with full cruising speed, nowadays. Consumers and businesses are looking to a 5G wireless connection to enable faster downlink/uplink speeds and high quality of service (QoS) that’s secure and reliable in new vertical applications of Smart transportation, industrial IoT, eHealth, Smart cities. As the commercial deployment of the 5G cellular networks is well underway, academia as well as industrial research organizations turn their attention to what comes next. 6G will focusing on the gap between beyond 2020 societal and business expectation driven by new technologies considered too immature or which are outside the defined scope of 5G. We identified three kinds of 5G+ core services for enhanced performance. Mobile broad bandwidth and low latency (mBBLL) service will provide a high-quality experience (QoE) in typical applications of mobile AR/VR and holographic teleconferencing. Next, massive broad bandwidth machine type (mBBMT) service enhances 5G mobile broadband and machine communication in typical application of tactile IoT. And finally, massive low latency machine type (mLLMT) service enhances ultra-reliable and low-latency communication in typical application of large scale industrial IoT. It was adopted a gradual evolution strategy and performance enhancement mechanisms based on investment in more spectral and hardware resources. However, we would point out current research progress towards 6G with some revolutionary technologies of wireless terahertz communications and artificial intelligence (AI). The advancement of wireless communications is highly restricted by basic sciences, especially mathematics and physics. Terahertz wireless communications is a rapidly growing and the recent significant progress anticipates the THz wireless systems realizable in the near future. AI-empowered 6G would enable the transformation from cognitive radio to intelligent radio as well as series of new features of self-aggregation, context awareness, self-configuration and opportunistic set-up. To justify our vision of future networks, we point out the need for closer connection of academia, standardizing bodies, industrial organizations and governments in demand-oriented roadmap. Research activities in 6G should not simply aim at adding more functions without considering the value of the implemented service in real-world.

11.00-11.45 Gagik Shmavonyan, Professor, National Polytechnic University of Armenia, Armenia. Title: Unique Nanostripes and Sheets of 2D Atomic Materials Obtained by Substrates Rubbing Technology.
2D atomic material unique nanostripes and sheets are obtained by substrates rubbing technology suggested by us. The substrates rubbing technology of making 2D atomic materials (atomic nanostripes, films, structures and devices) comprises putting pristine bulk (graphite, hexagonal boron nitride, molybdenum disulfide, etc.) layered material between two solid state (i.e. inorganic) substrates and rubbing the substrates against each other manually or mechanically in any direction, so that the crystalline powder uniformly spreads between them and covers the surfaces of two substrates with it. After a few circular rubbings of the powder with two substrates mono- and few layer nanostripes appear on the surfaces of both substrates. This technology for mass production of high quality and large-size mono- and few layer 2D materials has advantages over the similar technologies:
a) simple (one step), can be obtained even by hand, without using complicated nanotechnology equipment, hazardous toxic chemicals and high temperatures,
b) short-lasting (lasts a few tens of seconds),
c) cost-efficient (a few times, as no complicated nanotechnology equipment, hazardous toxic chemicals and high temperatures needed),
d) highly productive (production yield is almost 100 % and production rate is a few tens of tons/year),
e) ecologically clean,
f) controllable,
g) universal and unique (any 2D material can be obtained by rubbing technology).
The substrates rubbed nanostripes are mono-, few- and multiple atomic layers of exfoliated flakes organized in self-assembled narrow bands of nano-sized quantum dots, which are reported for the first time. The nanostripes consist of arrays of quantum dots, while sheets consist of nanostripes, and 2D atomic devices consist of sheets with nanostripes. 2D material nanostripes are obtained by rubbing graphite or other layered bulk materials on dielectric, semiconducting and metallic substrates at atmospheric pressure conditions. The size, shape and density-controlled nanostripes, embedded in different devices, as well as other factors greatly affect the device performance.

13.00-13.45 Nicolae Diga, Postdoctoral Researcher Engineer, Politehnica University of Bucharest, Romania. Title: Use of Modern Software Supports Specialized in Designing Induction Motors with Special Destinations.
In this paper, the authors propose to approach the design of three-phase induction motors with special destinations, using the modern specialized software supports. In this respect, by creating and exemplifying clear procedures for defining and simulating the generic model of a three-phase induction motor with squirrel-cage rotor, it is possible to respond quickly to the demands of the beneficiaries and to provide them optimal constructive variants. In this study, the software support “ANSYS Electronics Desktop” was used for the modelling and simulation from the electromagnetic point of view of an induction motor with a squirrel-cage rotor of 6 kV medium voltage having the rated power 225 kW, intended for the electrical pumping systems. The motors of this type drive mineral oil pumps for starting boilers or heavy fuel oil transfer pumps, within the own services of a thermoelectric power station. Thus, it was used for the analysis of the studied motor, the product ANSYS RMxprt Design which is an additional software tool to the ANSYS Maxwell Design solution, dedicated to electric machines designers. The software generates as interfaces, the simulation results of the analysis performed on the studied motor (performances, complete detailed design data, curves). The performances of the studied motor will constitute the input data for the subsequent analysis of the electromagnetic field performed by the finite element method. The simulation is performed both in operating regime at rated load and no load, starting, running with blocked rotor, the software also providing the consumption of materials necessary for motor construction. The software generates a custom file with the design data of the analyzed three-phase induction drive motor, which contains: general data; stator data; rotor data; consumption of materials; operation at rated load; operation no load; starting; operation with blocked rotor; detailed data when operating at rated load; the arrangement of the windings. With the help of this software product, the performances of the machine were calculated at different load levels in the domain (0.25 … 1.25)∙PN. Due to the facilities offered by the “Optimetrics” module of the software product used, a number of technical characteristics could be compared, such as the variation as a function of speed of: efficiency, η = f(n); power factor, cosφ = f(n); developed (useful) output power, P2 = f(n); the developed couple, M = f(n); the supply current from the stator winding, I = f(n), etc. Thus recommendations could be made regarding the adoption of solutions to ensure the efficient operation of this motor in terms of loading regime.

15:00-15:45 Ethel Petrou, Professor and Chair, Department of Physics, Erie Community College, State University of New York, USA. Title: The Challenges of Lab Teaching during the COVID 19 Pandemic
Science, Technology, Engineering and Mathematics (STEM) programs that attract and sustain student interest feature learning that is experiential, investigative, hands-on, personally significant to both students and faculty, connected to other inquiries, and suggestive of practical application to students’ lives. Such learning flourishes in a community in which faculty are committed equally to teaching, to maintaining their own intellectual vitality, and to partnering with students in learning, and in which institutional support for such a community exists. The CSIE (Creative Scientific Inquiry Experience) Program at Eastern Michigan University is involved in retaining and increasing the number of STEM graduates by including faculty professional development, student connectedness to the sciences and mathematics through academic service-learning, and curricular reform. Participants will share their own institutional experiences and strategies for recruiting and retaining their STEM majors, developing culturally relevant, community-based courses, and will explore ways for implementing such a program on their campuses.

17.00-17.45 Leslie Kerby, Assistant Professor, Idaho State University, USA Title: Using Data Analytics to Improve Government Financial Efficiency.
The goal of improving cost efficiencies is a constant endeavor of all organizations. This is especially true for governments, where public perception often has the ability to effect budget allocations. This paper explores the budget expenditures of the state of Idaho in the United States using data analytic techniques and suggests areas where improvements could be possible. Visualizations will be used extensively throughout the paper to illustrate results.
Data Exploration
The data used in this analysis consisted of publicly available state expenditures from 2018 and 2019. The dataset contains over 2 million state expenditures across all state agencies. Analysis was performed using Python and the pandas library. Visualizations were created using the matplotlib and seaborn packages. The data exploration showed that Idaho’s Departments of Health and Welfare, Education, and Transportation spent the most in this time period, with Health and Welfare spending the most by a large margin. This is of interest as health costs and insurance premiums have dramatically increased over the last 5 years and the future of this industry is uncertain. Changes in the year-to-year expenditures of the individual state agencies and vendors were investigated. In the area of health care, it was found that nearly all health districts in Idaho experienced a 3% average increase between 2018 and 2019. Assuming inflation cost on health care to be between 1 and 2 percent, it appears the cost of state expenditures in health increased close to 1% above inflation. Analysis of Idaho’s transportation costs shows that the state spent 40% of its transportation budget on out-of-state travel, with out-of-state lodging costing 88% more than in-state lodging and flight expenses costing nearly 34% more vs. in-state travel. Other areas of interest explored included university expenditures, corrections spending and computer technology expenses.
State-by-State Comparison
Data on Idaho’s spending in education, health and transportation was compared to publicly available records for the states of Iowa, California, Arkansas and Texas to see how Idaho compares to other states. Initial analysis has shown that on a per capita basis, the state of Idaho spent significantly less on healthcare services than the states of Iowa and California, while spending more on education than Iowa, but less than California. In the area of transportation, Idaho’s per capita spending is in line with both states. On a percentage basis, the initial analysis shows that Idaho has spent a larger portion of its budget on correction services than the state of Arkansas, and close to 30% more of its budget on transportation when compared to the state of Texas. Health care costs between Idaho and Arkansas are similar, with each state spending approximately 29% of its budget on health services. In education services, Idaho spent significantly less than both Texas and Arkansas. The analysis shows that Idaho spent less than 7% of its budget on education, while Arkansas and Texas spent 35% and 15%, respectively.
Conclusions and Recommendations
Cost efficiency in the area of transportation may be improved by increasing the use of video conferencing technology, providing incentives for workers to reduce travel expenses, capping personal vehicle reimbursement and considering contracts for out-of-state travel. Possible areas for improved efficiencies in health expenses include more accountability controls for redacted agents and the implementation of cost transparency standards for state approved providers. The analysis of Idaho’s expenditures, as well as the comparison between Idaho and other state budgets, allows for areas of potential improvement or waste to be identified. The ability to do this effectively with free tools, such as pandas, could entice local governments to expand their data science and analytic capabilities, as the benefits could save potentially millions of tax dollars.

09.00-09.45 Dimitris Argyropoulos, Finland Distinguished Professor of Chemistry, North Carolina State University, USA. Title: Limitations in Creating Lignin-Derived Carbon Fibers.
Single component lignin-derived carbon fibers have been under development for many years, but strength properties are still inferior to those of commercial carbon fibers. The extent of graphitization is an overlooked limitation to lignin-derived carbon fiber development, particularly for high-modulus fibers treated at high temperatures. The tensile moduli of commercial carbon fibers increase with temperature during graphitization, however, lignin-derived carbon fiber moduli stay the same or decrease. This review exposes the inability of lignin-derived carbon fibers to graphitize in a manner similar to commercial carbon fibers, thereby providing rationale for the aforementioned discrepancy in tensile moduli-temperature trends and offering possible tangible future areas of research and development.

We reported synthesis of organic-inorganic hybrid gels by hydrosilylation reaction of cyclic siloxane compound or cage silsesquioxane compound, as a joint monomer, and α,ω-nonconjugated diene, as a linker monomer, using a Pt catalyst. The reactions successfully yielded transparent gels, and their mesh size measured by a scanning microscope light scattering device ranged from about 1 to 2 nm. We have controlled the affinity between the network structure and the organic solvent of the organic-inorganic hybrid gels, and found out some reaction systems, which can form porous polymers. In the present examination, mixed solvents of toluene and methanol (and acetone) were used to control solubility parameter (SP) of the solvents. Toluene is a good solvent, and methanol and acetone are poor solvents for the siloxane compound. In the process of forming a network structure by hydrosilylation, it is expected that a porous polymer will be formed when polymerization induce phase separation occurs via spinodal decomposition in the mixed solvents. We selected 1,3,5,7,9,11,13,15-octakis(dimethyl- -silyloxy)pentacyclo[9,5,1,1,1,1] octasilsesquioxane (POSS), or 2,4,6,8-tetramethylcyclotetrasiloxane (TMCTS), as the joint molecules, and 1,5-hexadiene, divinyl or diallylsilane compounds, as the linker monomer. In this report, effect of the reaction conditions, SP values of the solvent, molecular structure of the joint and linker monomers, and monomer concentration on the production state and morphology of the porous polymers was precisely studied. In the case of the reaction of POSS and HD, the production state changed from transparent gel to porous polymer by increasing the SP value using a mixed solvent of toluene and methanol. The monomer concentration in POSS-HD reaction system affected the morphology of the porous polymer, and changed from the particle linked structure to the particle linked structure with increasing of the monomer concentration, at the boundary of 10 wt%. The monomer concentration may influence the structure in the phase separation via spinodal decomposition and the subsequent immobilization. In the reaction systems using divinylsilane compounds, the difference in the side chain structure, methyl group or phenyl group, affected the porous structure of the polymer produced. The reaction using divinyldiphenylsilane formed globules connected structure independent of the monomer concentrations, whereas the reaction using divinyldimethylsilane resulted porous polymer formed by small fine particles.

In the modern world the largest firms in the global economy noted on the Forbes Global 2000 list create the command and control function of cities. Of the ten possible sectors on the list, the materials sector was studied, which consists of firms in two subsectors: specialized chemicals and diversified chemicals. The materials sector is one of the weakest of the ten Forbes sectors. This is why it is important to examine the financial condition of firms in this sector, especially its largest firms. The purpose of the paper is to determine the financial rank of the largest firms in the materials sector noted on the Forbes Global 2000 list and their effects on the command and control function of cities. In this paper, we present a new comprehensive index of potential for selected cities based on revenue from sales, net profits, assets, and market value for selected sectors of the economy. A command control index (CCI) was created based on a comprehensive index of potential, number of sectors, and number of corporate headquarters. It has been shown that the materials sector is one of the weaker sectors among the largest world companies, both in terms of its totality and the financial performance of constituent firms, even though its value increased more than sixfold in the period 2006-2018. The materials sector is very often found in smaller cities – home to only one company generating their command and control function. This is very disadvantageous, as in the event of a crisis at this one company, the entire city may lose its command and control function. On the other hand, in large cities, its share is less than 10%. However, it is possible to identify cities where the significance of the materials sector has increased in the generation of the command and control function (Beijing, Shanghai, Hong Kong), and where it has substantially decreased (New York, Tokyo, London, Paris). A general increase in the significance of the sector has occurred in Asia, while a general decline has occurred in Western Europe and North America.

12.00-12.45 Eman Alam, Lecturer, Al-Azhar University, Egypt. Title: Pharmaceutical Biotechnology for the Production of Some Active Phytochemicals Against Tropical Diseases from Some Wild Egyptian Medicinal Plants.
Oxidative stress is the result of an imbalance in the body between the oxidizing system, consisting mainly of free radicals, reactive oxygen species (ROS) and reactive nitrogen species (RNS) (Camini FC et al., 2017), and antioxidant systems that neutralize these free radicals capable of multiple deleterious effects. This oxidative stress is involved in fighting many diseases such as; aging (Liguori I et al., 2018) and also it is found in certain chronic pathologies such as diabetes mellitus, cancers, hypertension, coronary heart disease, etc. (Yaribeygi H, 2020) and certain infections, particularly by the RNA viruses (Zhang Z et al., 2019), a family to which belong corona viruses (FMPMC-PS, 2020). It is well known that, oxidative stress is triggered by a wide variety of different viral infections (Zhang Z et al., 2019 and Ivanov AV et al., 2016) including HIV 1, viral hepatitis B,C,D viruses, herpes viruses, respiratory viruses, most of the RNA viruses (Ivanov AV et al., 2016) probably also corona viruses belonging to this family. Corona viruses are encapsulated RNA viruses with different types: the classic coronaviruses, responsible for moderate respiratory infections in general, the SARS-CoV and MERS-CoV involved in epidemics of more severe respiratory infections (FMPMC-PS, 2020) and the new coronavirus (SARSCoV2) discovered in January 2020 is responsible for infectious disease called COVID-19 which is currently experiencing a worldwide outbreak (Public Health France, 2020). Generally, viral infections lead to an increase in the production of free radicals and a depletion of antioxidants and as a result oxidative stresses will be accumulated inside the body (Camini FC et al., 2017). To fight Covid-19 infection, all the possible treatments deserve to be taken into account. Relying on the complex pathophysiology of this viral infection (COVID-19), the use of antioxidant agents must be taken in consideration during the treatment process (Marie-Pierrette Ntyonga-Pono, 2020). This study includes a survey on some Egyptian medicinal plants those have strong antioxidant activities (in addition to the use of green biotechnologies in the production of important antioxidant phytochemicals from these plants) to be suggested to be used in the treatment of COVID-19. The production of these phytochemicals is often low (less than 1% dry weight) and depends greatly on the physiological and developmental stages of the plant life. Applicable methods used for the enhancement of the in vitro production of these important antioxidant phytochemicals will be discussed also in this review article: 1. Selection of source materials. 2. Selection of superior cell lines. 3. Optimization of culture conditions. 4. Alteration of controls of secondary metabolism pathways. 5. Elicitation. 6.

The integration of STEAM domains (science, technology, engineering, arts and mathematics) is not an easy task, but it allows for greater stakeholder engagement, improved creativity, opportunities for innovation and tools for problem-solving and provides cognitive benefits for a holistic view of the situation. The ability to link these thematic areas and the sharing of these areas of knowledge allows for an improvement in teamwork skills, an incentive for critical thinking, a stimulation of interpersonal communication and adaptability (fundamental characteristics in the industry 4.0). It should also be noted that the union of these abilities illuminates the field of abstract thought, allows spatial resolution, openness to new ideas, experiences and new curiosities. The actions promoted by the STEAM concept give ideas a boost, stimulate risk taking and learn from mistakes. Experimentation of materials and manufacturing processes are mandatory in proposing new engineering ideas, as they carry the materiality of the product and / or system and thus the formal expression of the designer responsible for the project. Following the justification and relevance of this proposal, it is noteworthy that the interdependence between human and materials and process has made these incorporated into human culture becoming “substance of action” of civilizations over time. Just remember that the various ages through which man has gone through are characterized by the degree of development and utilization of materials and process: stone age (chipped and polished), bronze age, iron age; nowadays maybe we could say polymer age, composite age, multi-material age… What is certain is that knowledge of manufacturing processes and materials are almost always indispensable to materialize a conceptual project. In this sense, examples of integration between materials and manufacturing techniques notably in 3D printing and laser engraving and cutting will be presented and their relevance to materialize STEAM projects will be shown. The importance of STEAM concepts about personalization and industry 4.0 will also be discussed: can the STEAM approach be used in the future to better answer the issue of personalized product demand? Can it give new paradigms to better answer some 4.0 issues? Given this scenario it can be concluded that STEAM theme combines transdisciplinary, interdisciplinarity, multidisciplinary and even cross-cutting disciplines and is with an Integration of science, technology, engineering, arts and mathematics facing new paradigms in material selection, manufacturing processes and design that we can move forward in new challenges of design research and industrial engineering in the coming days.

14.00-14.45 Doros Petasis, Professor, Allegheny College, USA Title: Low Temperature EPR and Magnetic Susceptibility Studies of Cerium Nitrate-Triphenylphosphine Oxide and Cerium Vanadate Complexes.
Phosphine oxide and orthovanadate complexes of rare earth ions have many potential technological applications in a wide array of fields, especially in materials physics, chemistry and biomedical engineering. Many of these applications are due to the unique magnetic properties of these complexes. The present work is focused on electron paramagnetic resonance (EPR) and magnetic susceptibility experiments we carried out on phosphine oxide and orthovanadate complexes of the rare earth ion Ce (III). Low temperature EPR measurements of Ce (III) doped in a La (III) nitrate complex with triphenylphosphine oxide and Ce (III) doped in La (III) vanadate have been carried out in order to gain a better understanding of the electronic properties of Ce in these compounds. The complexes Ce:La(NO3)3(Ph3PO)4(Me2CO) (1) and Ce:La(NO3)3(Ph3PO)2(EtOH) (2) have been synthesized using established methods such as the reaction of Ce/La nitrate hexahydrate and triphenylphosphine oxide in acetone (1) or ethanol (2) in air. Ce:LaVO4 solutions were prepared by reacting Ce/La nitrate hexahydrate (Ce/La(NO3)3∙6H2O) and sodium orthovanadate (Na3VO4) in an aqueous environment. Single crystals of these complexes were grown under a variety of conditions to ensure that the crystals were free of defects and inclusions. X-band EPR spectra of the crystals were collected at liquid helium temperatures to allow the determination of the order and energy separation of the three Kramers doublets J=5/2; Jz=1/2, J=5/2; Jz=3/2 and J=5/2; Jz=5/2 in the 2F5/2 ground state manifold of Ce (III). The information from EPR experiments, along with AC magnetic susceptibility measurements, will allow us to better understand how the crystal field influences the magnetic properties of these crystals. The EPR spectra and magnetic susceptibility measurements as well as the crystal synthesis techniques will be presented along with some potential applications of these interesting complexes.

17.00-17.45 Jeffrey Busch, Senior Consultant and Adjunct Professor, Portland State University, USA. Title: Agile-Stage-Gate Approach: Exploratory Research on the Structure, Roles, and Responsibilities.
One of the more prominent methodologies gaining recognition in recent years is the Agile-Stage-Gate approach. The relatively new hybrid model is a combination of the Stage-Gate and the Agile-Scrum models. A number of companies that are using the Stage-Gate process have recently adopted the Agile-Stage-Gate approach to improve their product development and project management practices. However, each of these companies made adjustments and modifications to the new approach in order to accommodate their specialized needs and to achieve the goals that are unique to their company. Therefore, no fixed structure or standardized features have been explicitly assigned to this hybrid approach. Instead, each company incorporated different features and manipulated the new approach to fit whatever needs that would arise from moment to moment along the way. This ambiguity leads to the question of whether the structure, roles, and responsibilities of this new approach can be defined and if so, how clear and consistent definitions could improve productivity, efficiency, communication and market response time. The purpose of this study was to explore the structure, roles, and responsibilities within this new approach and to identify patterns that emerge during the product development and project management processes. The research questions presented were administered and examined through a qualitative survey. Fifty-two complete responses were collected from experienced individuals who have varying degrees of experience with the Agile-Stage-Gate approach. These findings revealed many similarities and differences between the structure, roles, and responsibilities of this approach, many of which were also dependent on the product and project type being considered. The most apparent similarities between roles and responsibilities were found in the combined software development with the new product development projects. The findings support most of the research outcomes as outlined in the literature review. The study also revealed that the hybrid approach can also improve the management of stand-alone product development projects as well, which is a very promising result for manufacturing firms that are willing to adopt this hybrid approach for their projects. Along with the significant and undeniable impact on team communication and performance, the Agile-Stage-Gate approach was shown to improve overall quality and productivity. Another important finding from this study is the significant benefit of the Agile-Scrum model that was not limited to a specific stage of typical product development life-cycles. Rather, manufacturing firms indicated that they can apply this integrated approach throughout all life-cycle stages within the Stage-Gate model. This research provides strong evidence that the hybrid approach is a promising model when it comes to managing in a combined manner, technology and new product development projects.
