Published: June 2023

In an article based on unpublished archival documents from the funds of the Department of Public Education, the Office of the minister S. S. Uvarov and the collection of the Imperial decrees, rescripts and loyal reports, the “restraining” elements of the imperial policy in education, their mechanisms and features on the territory of the “provinces returned from Poland” are analyzed. Particular attention is given to the reasons of administrators’ struggle with Polish influence in educational institutions. In the context of the “depolonization” policy, minister S. S. Uvarov’s project on the creation of the University of St. Vladimir in Kiev and its practical implementation are examined. The problem of the limited power of the Ministry of Public Education in the entrusted affairs due to the predominance of emergency mechanisms of administrative and police control in the territory of the Kiev educational district is also being investigated.
Biological stations in the Russian empire: organization and financing
Authors:   St. Petersburg branch of S. I. Vavilov Institute for the History of Science and Technology RAS, Zharova Ekaterina Yu.
Published: June 2023

The article presents the features of the organization and financing of marine and freshwater biological stations. The history of the biological stations was described from the point of mainly biography or the scientific interests of the researchers who worked there. However, this shows only one side of their activity. This article comes to the other side, how the stations were organized and who controlled them, as well as who gave money for their activities. The founders of the stations were mostly university professors; however, the stations were not directly subordinated to universities, but to scientific societies. Such subordination was the reason of bureaucratic obstacles: in order to organize stations at universities, it was necessary to obtain official permission from the minister, and then receive funds from the university, which itself needed them. This was the reason that professors preferred to use scientific societies that provided money from membership fees, or use their own funds. The patronage was also used. The ministries of public education and agriculture and state property, which were the most interested in the stations, gave money extremely reluctantly and irregularly. Therefore, the stations experienced chronic financial needs and needed funding all the time during the imperial period.
Photoredox catalysis enabling decarboxylative radical cyclization of γ,γ-dimethylallyltryptophan (DMAT) derivatives: formal synthesis of 6,7-secoagroclavine
Authors: Regni Alessio , Bartoccini Francesca , Piersanti Giovanni
Published: June 2023

An unusual photoredox-catalyzed radical decarboxylative cyclization cascade reaction of γ,γ-dimethylallyltryptophan (DMAT) derivatives containing unactivated alkene moieties has been developed, providing green and efficient access to various six-, seven-, and eight-membered ring 3,4-fused tricyclic indoles. This type of cyclization, which was hitherto very difficult to comprehend in ergot biosynthesis and to accomplish by more conventional procedures, enables the synthesis of ergot alkaloid precursors. In addition, this work describes a mild, environmentally friendly method to activate, reductively and oxidatively, natural carboxylic acids for decarboxylative C–C bond formation by exploiting the same photocatalyst.

The Nonlinear Effect of Population Aging and Socio-economic Conditions on Carbon Emission: An Empirical Analysis of 30 Provinces and Regions in China
Authors:   The Korean Data Analysis Society, Luo Zhenxing , Zhao Yanwei , Lim Jungmin
Published: June 2023

The central aim of this paper is to provide a comprehensive analysis of the impact of population aging on carbon emissions in China. In order to attain a deeper comprehension of this effect, this study investigates the non-linear relationship between population aging and carbon emissions through empirical analysis of 30 provinces and regions in China from 1997 to 2019 using a panel threshold model. Our primary research findings indicate that the correlation between population aging and carbon emissions demonstrates nonlinearity. Population aging has had an inhibitory effect on carbon emissions; however, as the aging population continues to increase, its effect on suppressing carbon emissions will weaken. Moreover, we have also uncovered non-linear relationships between energy intensity, per capita GDP, industrial structure, and carbon emissions. Notably, despite rapid growth in total fossil energy consumption, energy intensity has shown a decreasing trend in China, which has mitigated the upsurge in carbon emissions attributed to fluctuations in energy intensity. The positive correlation between GDP per capita and carbon emissions is evident, but there is little variation observed across different threshold levels. Finally, the relationship between industrial structure and carbon emissions is considerably intricate, our results show that a U-shaped curvilinear relationship exists between the two variables.

MULTIPALEOIBERIA: hacia un nuevo escenario sobre las dinámicas de poblamiento y adaptaciones culturales de los últimos neandertales y primeros humanos modernos en el interior de la península ibérica
Authors: Alcaraz-Castaño Manuel
Published: June 2023

Históricamente, la península ibérica ha presentado un registro de gran relevancia para el conocimiento de las sociedades paleolíticas. Sin embargo, en lo referido a la primera ocupación de humanos modernos y la desaparición de los neandertales, dicho registro presenta un problema fundamental: la anómala escasez de evidencias en las amplias regiones del interior peninsular. El proyecto MULTIPALEOIBERIA, financiado por el Consejo Europeo de Investigación (ERC), asume que dicha escasez se debe a un déficit histórico de la investigación. Por ello, plantea la hipótesis de que la ocupación humana del interior de Iberia durante este periodo fue más compleja y duradera de lo asumido tradicionalmente, y tiene como objetivo principal obtener nuevos datos para contrastar las visiones clásicas. Se plantea como un macro-proyecto interdisciplinar y colaborativo aplicado a varios territorios de las dos submesetas ibéricas, y con la interacción entre cultura, ambiente y clima como marco de investigación fundamental. Su metodología implica la búsqueda de nuevos yacimientos, trabajo de campo en al menos 24 localizaciones arqueológicas, paleoecológicas o rupestres, un amplio programa de datación cronométrica, una detallada reconstrucción paleoambiental multi-proxy, así como el análisis de las estrategias tecno-económicas, simbólicas, de movilidad y uso del territorio de los últimos neandertales y primeros humanos modernos en el interior peninsular. Se espera que sus resultados presenten un alto impacto en temas como la potencial pervivencia tardía de neandertales en el sur de Europa, la naturaleza y cronología de la primera ocupación de humanos modernos de la península, o las adaptaciones culturales de cazadores-recolectores pleistocenos a contextos de rigurosidad climática y alto riesgo ecológico. En este artículo se presentan las hipótesis, objetivos, marco teórico-metodológico y primeros resultados de MULTIPALEOIBERIA.

Businesses that engage in sustainable marketing can benefit both the world and their bottom line. Earlier, companies could satisfy many customers by simply providing low pricing and high-quality goods. However, people's concern for the environment and other social concerns have grown, and so has their desire to support groups that share their beliefs. Because they often generate strong market returns and demonstrate durability during economic downturns, many investors want to support businesses that use sustainable business methods. Also, these businesses are more likely to comply with social and environmental laws. Several companies use sustainable marketing to succeed in today's ethical and ecologically sensitive marketplace. Organizations must finance sustainability programs in order to practice sustainable marketing. But, it can also improve employee engagement, promote regulatory compliance, raise revenues, and build brand loyalty.
Sustainable Healthcare Reforming Model Based on Marketing
Authors: Djakeli Kakhaber
Published: June 2023

Discourse about sustainable marketing is not finished. The theme is very current, and it involves either business or government responsibility of sustainability, green marketing, and sustainable lifestyle. Sustainability marketing in healthcare reforming is oriented to societal goals and special type of approaches to society as a whole. The healthcare reforming must be totally devoted to people, but environmental and societal scanning is the business of societal marketing. What can be the special type of advantage of health marketing and reform marketing? If health reformers try to meet present goals of society and at the same time consider the environmental, green policies, societal problems, and meet the goals of next generation, such health reforming, they can be called sustainable health reforms.

Identifying SARS-CoV-2–specific T cell epitope–derived peptides is critical for the development of effective vaccines and measuring the duration of specific SARS-CoV-2 cellular immunity. In this regard, we previously identified T cell epitope–derived peptides within topologically and structurally essential regions of SARS-CoV-2 spike and nucleocapsid proteins by applying an immunoinformatics pipeline. In this study, we selected 30 spike- and nucleocapsid-derived peptides and assessed whether these peptides induce T cell responses and avoid major mutations found in SARS-CoV-2 variants of concern. Our peptide pool was highly specific, with only a single peptide driving cross-reactivity in people unexposed to SARS-COV-2, and immunogenic, inducing a polyfunctional response in CD4+ and CD8+ T cells from COVID-19 recovered individuals. All peptides were immunogenic and individuals recognized broad and diverse peptide repertoires. Moreover, our peptides avoided most mutations/deletions associated with all four SARS-CoV-2 variants of concern while retaining their physicochemical properties even when genetic changes are introduced. This study contributes to an evolving definition of individual CD4+ and CD8+ T cell epitopes that can be used for specific diagnostic tools for SARS-CoV-2 T cell responses and is relevant to the development of variant-resistant and durable T cell–stimulating vaccines.
Use of Hunting Tooth for Gear Fault Detection
Authors:   GPMS International Inc., Becchoefer Eric
Published: June 2023

This paper looks at the use of the hunting tooth (HT) time synchronous average (TSA) to improve fault detection on gears. HT analysis is based on the period at which two damaged teeth mesh. The HT frequency tends to be low, requiring a long acquisition in order to calculate the TSA. Because of the long acquisition, the HT TSA may improve the signal-to-noise of some gear fault pairs, such as seen in the epicyclic gearbox planet/ring gear mesh. This study develops two CIs based on the HT TSA from two different data sets. The first data set has been used to quantify the performance of gear algorithms using statistical separability. The second data set is from an OH-58 gearbox that was seeded with a damaged planet gear. Planet gears are typically difficult to analyze as if only one planet has damage, and the fault may be masked by the other good planets, making early fault detection difficult. The proposed CI showed good fault detection and trends for both data sets and was superior for the epicyclic gearbox. The performance of the HT TSA and new CIs is quantified relative to other gear CIs.

Additive friction stir deposition (AFSD) is a novel additive manufacturing (AM) technology in which solid-state, friction-stirred metal is deposited layer-by-layer to build three-dimensional parts. Unlike the mainstream fusion-based AM methods, AFSD does not cause metal melting and solidification. Therefore, AFSD can eliminate defects such as lack-of-fusion, key-holing, and large residual stress. Currently, the understanding of AFSD is based on the friction stir welding (FSW) process that has been widely studied for the past two decades. However, the material feeding and spreading in AFSD is essentially different from FSW and can complicate the thermal field and material flow. In this work, a computational fluid dynamics (CFD) model is created to simulate the temperature and fluid flow for AFSD of aluminum 7050 alloys. The predicted temperature is validated against both literature and thermocouple measurements. The current work lays the foundation for a quantitative understanding of AFSD process physics and the simulation-guided process design to tailor the thermal-mechanical field.

Published: June 2023

Virtual V-22 critical azimuth data was collected in the Manned Flight Simulator at Naval Air Station Patuxent River using a new developmental un-validated blade-element-model. The virtual data was compared to live data that had mirrored test conditions as a way to create a process for model validation. Pilot ratings and comments enabled assessment of the relative workloads between the live and simulated test points. In the future, this quantitative and qualitative data will be one of the building blocks to help with simulation validation for multiple type/model/series aircrafts. The process is defined here and initial comparisons with the un-validated model return promising results.
Development of Parametric Rotor Control Equivalent Turbulence Input (RCETI) Models for Rotorcraft
Authors:   Georgia Institute of Technology, Hayajnh Mahmoud , Prasad J.V.R.
Published: June 2023

This paper presents an extension of previous research that aims to generalize the hover/low-speed Control Equivalent Turbulence Inputs (CETI) models for different helicopter configurations. The rotor hub-loads are utilized as the outputs to which the turbulence-related spectra are matched in order to achieve this generalization. Additionally, the rotor swash-plate deflections are considered as inputs to create what is referred to herein as the Rotor Control Equivalent Turbulence Inputs (RCETI) model. The development of the RCETI model, which aims to produce rotor loads spectra similar to those generated by vertical turbulence, is conducted using a representative model of the UH-60 helicopter in FLIGHTLAB®. The analysis is performed as a Multiple-Input Multiple-Output (MIMO) case, and the results are compared to the Single-Input Single-Output (SISO) cases. Furthermore, the effect of altering the rotor parameters on the RCETI model is studied and presented in the paper.

Published: June 2023

The emergence of Urban Air Mobility (UAM) as a novel mode of transportation presents new challenges to government and commercial stakeholders: new vehicle types are being introduced for which supporting infrastructure, such as new routes and vertiports, needs to be designed and put in place, often in the vicinity of airports; community concerns need to be addressed; and inclement weather is a potential disruptive factor. In this new UAM paradigm, simulation modeling is an indispensable tool for aviation planners in identifying optimal solutions to these challenges. AvMet and Kimley-Horn have developed an efficient process for UAM simulation study planning and execution, facilitating rapid turnaround through collaborative model development. This streamlined process, from UAM airspace design and flight schedule development to fast-time simulation modeling, to advanced 3D visualization, can greatly reduce the study completion time and allow for a variety of UAM scenario alternatives to be explored, evaluated from a cost-benefit perspective, and presented to stakeholders. A key component of this process is AvMet's state-of-the-art UAM Simulation Model (USM). In this paper, we provide UAM scenario setup examples and simulation results utilizing the USM, as well as describing the study planning and modeling process.

Wildfires are an annual torment in many parts of the world. They can spread very quickly and destroy forests, wildlife, buildings, infrastructure, and homes, as well as risk human life before they are able to be controlled. Because of the rapid response time that is necessary to extinguish a wildfire before it becomes too large, the quantity and speed of water delivery are extremely important - helicopters are a great tool for accomplishing this goal. They can fly directly to the fire and refill their water supply from smaller, more remote water sources than other aerial platform options require. There are several water tank options to transport and drop water on the fire from a helicopter. This paper focuses on four of these options: an external rigid tank, an accordion tank, a Bambi Bucket® 1, and an internal tank in addition to the outlining some of the options for remote water sourcing. Each of these tank types have various advantages and disadvantages which are discussed using models developed for evaluating helicopter firefighting applications.
Development of an Operational Analysis Tool for Urban Air Mobility
Authors:   Georgia Institute of Technology, Smith Marilyn , Crawford Aaron , Carozza Kyle
Published: June 2023

The current interest in autonomous urban/advanced air mobility (U/AAM) capabilities raises important questions regarding the safety, maintenance, cost, and life cycles of UAM vehicles to produce a business case, in particular as operations will be in significantly different environments. Accurately estimating a vehicle's aerodynamic and structural behavior, combined with a knowledge of material properties and operational sensor data, permits the prediction of vehicle fatigue throughout its life cycle. This should result to less scheduled maintenance, less time out of operation, and therefore a lower overall operational cost. Under NASA University Leadership Initiative (ULI) funding, Georgia Tech and their partners are addressing this problem through the development of an Operation Analysis Tool (OAT) for U/AAM platforms of varying size and configuration. The OAT seeks to provide a framework for real-time analysis of UAM vehicles in various flight conditions allowing for rapid prediction of structural responses and other safety-related events. The current version of the tool, along with planned improvements are described in this paper.

Published: June 2023

The combined adhesive wear resistance of both all-steel and hybrid (Si3N4 and steel) interfaces lubricated by rotorcraft gearbox lubricants was evaluated. Bench-level tribological tests were utilized to rank selected material and lubricant combinations. Material pairings of M50 balls with M50 cylinders, and Si3N4 balls with M50NiL cylinders, were selected for the comparison. This work includes three fully formulated aerospace oils: 1. a MIL-PRF-32538 9 cSt polyol ester, 2. an unclassified ISO VG 68 synthetic hydrocarbon, and 3. a DOD-PRF-85734 5 cSt polyol ester. The results offer a relative comparison of rotorcraft gear oil formulations and their efficacy in reducing the onset of adhesive wear in both all-steel and hybrid interfaces.

Authors:   Hexagon, Mahmoud Hanafy , Scott Phillip
Published: June 2023

Electric powered vertical take-off and landing (eVTOL) vehicles are in development for urban air mobility, as they have zero emissions and support a reduction of traffic congestion. A long-range eVTOL aircraft requires a propulsion unit with challenging requirements for power and torque densities, efficiency, reliability, safety, and environmental sustainability. This paper deals with designing an efficient high-TRL direct-drive electric machine (E-machine) with high power and torque density for the propulsion unit. As an example, City Airbus eVTOL's requirements have been considered as a baseline. The work-flow proposed demonstrates the feasibility of designs that push both active power density and torque density of the studied E-machine to more than the twice that of the current system. The proposed approach includes investigations of the optimum slot/pole combination, air-gap length, number of three-phase groups and advanced materials. Furthermore, a fast multi-objective optimization approach based on a meta-model of optimized prognosis (MOP) has been applied.

Published: June 2023

In this work, the procedure for experimental validation of a pericyclic transmission is described. From its conception in 1970's, the nutating (now pericyclic) mechanical transmission has undergone several years of rigorous analysis in hopes of addressing common drivetrain considerations of noise, maintenance, and power density. These analytical studies have led to the fabrication of a 50 HP 32:1 reduction ratio prototype, meant to demonstrate whether it can achieve the theoretical design goals. The final analyses will be detailed characterizations of the system's torque transmission, thermal efficiency, and vibration under dynamic load. This paper outlines the successful assembly and alignment procedures, validated by contact pattern and tooth strain, as well as the experimental layout for the dynamic testing of a pericyclic transmission.
