Published: April 2023

New geopolitical challenges that necessitate the formation of a nationally oriented education system require a multidimensional analysis, socio-cultural understanding and the search for new formats for the organization of higher education in Russia. In the conditions of the post-Bologna reality, Russia needs to create its own model of higher education, which will be able to provide the economy with highly qualified personnel, which will coopt all the best from the classical Soviet system of education and will be able to build on the national traditions, interests of students, their parents, teachers and employers. In this regard, it is relevant to analyze and evaluate the requests of nowadays students for these changes and the nature of those changes.The article is based on the materials of the authors’ sociological research (N=123977 people), conducted in 2022.The problematic area of the research supposed that the revision of the existing predominantly two-level (bachelor and master) structure of higher education requires a transition to the optimal and traditional for Russia model of the specialist program with the introduction of more flexible forms of work, the possibility of changing the educational trajectory in the learning process, the search for new ways of academic mobility and universities cooperation.The research data are compared with the data of similar works of Russian and foreign analysts. An analysis of the opinion of Russian students showed that in the process of learning and gradually entering a specialty, some students need certain changes in the chosen training program made upon admission. The possibility or impossibility of implementing these changes determines their motivation for learning, academic achievements, further educational and professional trajectories, and satisfaction with education in general. Based on the analysis done and the results obtained, the authors propose practical steps to form a new structure of higher education based on the specialist program. They suggest recommendations on the necessary changes in the legislative, organizational, educational and methodological nature related to this process.

Published: April 2023

The article deals with the practices and specifics of the implementation of transformation projects in Russian universities. Particular attention is focused on the direct performers – members of project teams. The specifics of their formation are considered, the criteria necessary for employees to be included in a project team, as well as the peculiarities of such team functioning and development for more effective and productive activities are studied. The peculiarities of exclusion and withdrawal of employees from the project team – what are the reasons for it and what actions are taken by the head of the team to replace the withdrawn participant (selection of a new or redistribution of functions of the withdrawn to the remaining employees or another option) are considered separately.The conclusions presented in the article are based on the materials of an empirical sociological study conducted during the year (in the period from December 2021 to December 2022) by the method of indepth semi-formalized interviews with 78 representatives of administrative and managerial staff, scientific and pedagogical workers, heads of departments and deans of universities in three regional classical universities (in Siberian and Volga Federal Districts of the Russian Federation).Based on the results of the empirical study, the authors come to several conclusions. The transformation projects implemented in universities are associated with many diverse problems, key among which were: the destruction of agreements due to geopolitical risks; lack or complete absence of funding; varying financial success of projects; disunity of the team and lack of understanding of common goals and objectives of the project; lack of practical implementation of the project, etc.The success of the transformation project is signaled by both classical criteria called in the theory and practice of project management, for example, compliance with project deadlines, project execution within the allocated resources, and criteria less frequently mentioned in research, for example, the development of the project team, the formation of project values and norms of project culture, satisfaction of stakeholders and others. Transformation project teams are often formed spontaneously, the basis is often the potential candidate’s belonging to the required position or function, the competencies of candidates are rarely assessed, and their future competence and role statuses are planned.

Published: April 2023

<p>Foundation piles have the potential to improve the economic and <a href="https://www.sciencedirect.com/topics/engineering/technical-feasibility" target="_blank">technical feasibility</a> of ground source heat pump (GSHP) systems. They simultaneously provide structural support and energy for space heating and cooling. In this study, a thoroughly verified and validated numerical model of a novel in-ground heat exchanger for GSHP systems is developed and used to simulate and optimize performance. Commercially available helical steel casings with nominal sizes according to the American Petroleum Institute (API) of API 13.5, API 23, API 29, API 53, API 60, and API 68 were considered. The flow rates considered were 1 L/min, 2 L/min and 4 L/min for <a href="https://www.sciencedirect.com/topics/engineering/laminar-flows" target="_blank">laminar flow</a> and lower pressure drops. Results show the performance to increase with increasing pile size owing to improved heat transfer and longer residence times. Optimizing performance with an API 68 steel casing, (with a 2” nominal plastic pipe) gives a capacity increase of 0.01 ton/pile (or 8.3%), which would reduce the approximate pile array required for a 3 ton cooling system from 13 to 12. Doubling the size of this pile while keeping other parameters constant gives an 18.5% capacity improvement with an output capacity of 0.28 ton/pile, and an 11, 20 m pile array requirement to meet a 3 ton cooling load. With a maximum heat exchange rate of 58.6 W per meter depth, this shallow in-ground heat exchanger has the potential to minimize energy and costs for small-scale implementation. In addition, the possible low flow rates help reduce pumping power requirements. This study provides a foundation for sizing and design of helical steel piles. Moreover, the study also gives insights into pile performance in multi-layered soils where the <a href="https://www.sciencedirect.com/topics/engineering/thermal-conductivity" target="_blank">thermal conductivity</a> varies with depth.</p>

Authors: Bagdi Zsolt , Bakó Gábor , Molnár Zsolt 
Published: April 2023

Maintaining and enhancing aviation safety at all times is an essential factor at various airports around the world. It is not enough to keep it at that level, as we also see from history that the volume of air traffic doubles almost every 15 years. The number of aircraft in traffic is constantly increasing, and airport infrastructure needs to be developed. Consequently, the challenges for aviation are also greater. Electronic Terrain- and Obstacle Data Collection (eTOD) at airports and their surroundings are an essential procedure for aviation safety that aims to organize databases of potentially dangerous flight obstacles. The process is based on passive optical aerial remote sensing from a fixed-wing aircraft. With the help of point cloud and geoinformatics software created during the processing of in-flight recordings and additional data, strictly defined terrain- and obstacle data can be organized into databases, the format of which is regulated by international standards and documents, according to which the obstacle database can be used internationally. These data sets are needed not only because they are required by law, but also because they form the basis for the design of various aircraft procedures and make a major contribution to safe aviation.

Con el objetivo de diseñar una pirámide cuadrangular de base y apotema iguales al Número Áureo, se calcularon las Secciones Áureas para relacionarlas con las Constantes Físicas Universales y sus vínculos con la Física Cuántica. Existe poca información que expongan las propiedades de los prismas en relación al efecto fotoeléctrico. Se realizó una compilación bibliográfica y revisión audiovisual para analizar los contenidos temáticos.
Para el diseño geométrico se utilizaron los programas: Autocad (ver. 2017), el editor matemático Daun Equation Editor (ver. 2018) y la calculadora Magic Number 2 (ver. 2018). La pirámide diseñada es geométricamente armónica y matemáticamente contiene valores puros. Existe una relación que asocia al Número Áureo con el Número de Balmer (B), la Constante de la Estructura Fina (α) y la Constante de Rydberg (Rh). Estas re­laciones desvelan las propiedades de un prisma de cristal (pirámide) que refracta un rayo de luz para revelar que la luz blanca está compuesta por los colores del arcoíris, perturbación ondulatoria electromagnética que se percibe a través de nuestra vista y que se observa por medio del proceso de dispersión. Los resultados de este trabajo permitirán exponer la analogía geométrica de un prisma en relación a la física cuántica.

Graphical AbstractMechanisms by which exposure to cisplatin disrupts the inner ear system are not yet known. Here, we show that cisplatin exposure is associated with dysregulation of oxidative stress in the inner ear of the rodent. Furthermore, we found that, unlike controls, the response parameters of auditory cells of rats exposed to cisplatin were related to an imbalance in copper metabolism. These data suggest that curcumin related changes in the inner ear are depend on their effects on the mechanism of balance of the copper metabolism and that exposure to cisplatin can disrupt the plastic copper metabolism mechanisms needed to restore normal processing in peripheral auditory cells after hearing loss.

BackgroundNew multi-purpose prevention technology (MPT) products are needed to prevent human immunodeficiency virus (HIV) and herpes simplex virus type 2 (HSV2). In this study, we evaluated a fast-dissolve insert that may be used vaginally or rectally for prevention of infection.ObjectiveTo describe the safety, acceptability, multi-compartment pharmacokinetics (PK), and in vitro modeled pharmacodynamics (PD) after a single vaginal dose of an insert containing tenofovir alafenamide (TAF) and elvitegravir (EVG) in healthy women.MethodsThis was a Phase I, open-label, study. Women (n=16) applied one TAF (20mg)/EVG (16mg) vaginal insert and were randomized (1:1) to sample collection time groups for up to 7 days post dosing. Safety was assessed by treatment-emergent adverse events (TEAEs). EVG, TAF and tenofovir (TFV) concentrations were measured in plasma, vaginal fluid and tissue, and TFV-diphosphate (TFV-DP) concentration in vaginal tissue. PD was modeled in vitro by quantifying the change in inhibitory activity of vaginal fluid and vaginal tissue against HIV and HSV2 from baseline to after treatment. Acceptability data was collected by a quantitative survey at baseline and post treatment.ResultsThe TAF/EVG insert was safe, with all TEAEs graded as mild, and acceptable to participants. Systemic plasma exposure was low, consistent with topical delivery, while high mucosal levels were detected, with median TFV vaginal fluid concentrations exceeding 200,000 ng/mL and 1,000 ng/mL for up to 24 hours and 7 days post dosing, respectively. All participants had vaginal tissue EVG concentrations of &gt; 1 ng/mg at 4 and 24 hours post dosing. The majority had tissue TFV-DP concentrations exceeding 1000 fmol/mg by 24 – 72 hours post dosing. Vaginal fluid inhibition of HIV-1 and HSV-2 in vitro significantly increased from baseline and was similarly high at 4 and 24 hours post dosing. Consistent with high tissue TFV-DP concentrations, p24 HIV antigen production from ectocervical tissues infected ex vivo with HIV-1 significantly decreased from baseline at 4 hours post dosing. HSV-2 production from tissue also decreased post treatment.ConclusionsA single dose of TAF/EVG inserts met PK benchmarks, with PK data supporting an extended window of high mucosal protection. PD modeling supports mucosal protection against both HIV-1 and HSV-2. The inserts were safe and highly acceptable.Clinical trial registrationClinicalTrials.gov, identifier NCT03762772.

IntroductionRecent evidence suggests that the bone marrow (BM) plays a key role in the diffusion of P. falciparum malaria by providing a “niche” for the maturation of the parasite gametocytes, responsible for human-to-mosquito transmission. Suitable humanized in vivo models to study the mechanisms of the interplay between the parasite and the human BM components are still missing.MethodsWe report a novel experimental system based on the infusion of immature P. falciparum gametocytes into immunocompromised mice carrying chimeric ectopic ossicles whose stromal and bone compartments derive from human osteoprogenitor cells.ResultsWe demonstrate that immature gametocytes home within minutes to the ossicles and reach the extravascular regions, where they are retained in contact with different human BM stromal cell types.DiscussionOur model represents a powerful tool to study BM function and the interplay essential for parasite transmission in P. falciparum malaria and can be extended to study other infections in which the human BM plays a role.
