Nomination of heroes in the Anglo-Saxon epic "Beowulf"
Authors: Wuren Gaowa
Published: September 2023

The subject of the study are the peculiarities of the nominations of heroes in the archaic Anglo-Saxon epic "Beowulf". The language nomination, which is a complex and multifaceted phenomenon, is closely related to a person's understanding of the surrounding world and plays an important role in language. However, despite its importance, the study of this issue remains insufficiently studied. The purpose of this study is to examine the uniqueness of the hero nominations in Beowulf, analyzing the hero nominations not only etymologically, but also considering their potential meanings in context. To achieve the purpose of the study, various methods were used, including interpretive, word-formation, descriptive and etymological approaches. The results of the study can be used in teaching lecture courses on the Old English history and lexicology of English and, in reading special courses on linguocultural studies. The scientific novelty of the study lies in the fact that it conducted a comprehensive review of the system of hero nominations in the epic poem "Beowulf". It is concluded that the nominations of heroes in Beowulf are characterized by the use of proper names, which can be classified into monothematic, dithematic and suffix-monothematic names. On the other hand, there are various nominations based on common names, enriched with rich stylistic techniques, such as kenning, metaphor, etc. The nomination of heroes can change in different situations, reflecting the language, culture and values of the ancient Anglo-Saxon society.

Do Early Words from New Ventures Predict Fundraising? A Comparative View of Social Media Narratives
Authors: Havakhor Taha , Golmohammadi Alireza , Sabherwal Rajiv , Gauri Dinesh
Published: September 2023

Online equity markets have significantly changed the dynamics of connecting angels and individual equity investors to new ventures that seek early-stage capital. However, for those early-stage investors, information pointing to the success of business-to-business (B2B) new ventures (B2BNVs) is scattered and disconnected. This paper focuses on social media narratives (SMNs) as a source of insight for such investors and proposes that predicting a B2BNV’s likelihood of success requires a comparative view, i.e., a comparison of its SMNs with those of its competitors and customers. We expect that higher (lower) lingual similarity between the SMNs of an early-stage B2BNV and those of its prospective customers (competitors) predict its success. Using a longitudinal panel of 574 B2BNVs resulting in more than 2,700 venture-round observations, we find that a comparative view of a venture’s SMNs can give early-stage investors reliable predictions about the B2BNV’s ability to manage its market presence and its success in later stages. Our models show that a comparative view of SMNs increases the accuracy of predicting a B2BNV’s later-stage fundraising success by an average of 15%. Furthermore, predictive models can reliably point to a successful market presence in later stages, including the landing of customers, the winning of awards and competitions, the receiving of endorsements, the generating of revenue, and the successful patenting of products. Our study contributes to existing literature that focuses on the business impacts of social media by demonstrating the usefulness of comparative linguistics in social media analytics, i.e., comparing the firm’s social media communications to those of its competitors and business customers in the prediction of the entrepreneurial firm’s success.
Standardize or Let a Thousand Flowers Bloom? Interface Design Coordination between Software Platforms and Hosted Apps
Authors: Zhang Cheng , Song Peijian , Lim Kai
Published: September 2023

Software platform ecosystems are emerging as a dominant model for IT-based services. To accelerate third-party development, platform owners often waive restrictions on app user interfaces to provide app developers with more autonomy in interface design. The literature has indicated, however, that standardized interface design across products is a strategic necessity for firms to introduce and manage their product lines, suggesting that platform owners should not waive restrictions on app user interfaces. This tension between the two approaches raises a crucial research question: Does standardized interface design used by apps and their host platform benefit the platform and apps that it hosts? Specifically, does the coordinated design approach enhance or hinder usage between the platform and apps such that apps attract usage from their host platform and vice versa? Drawing on the theory of basic Gestalts, we theorize the three interface design properties of interface similarity, embeddedness, and synchrony, and extend the theory to investigate how these properties help both apps and their host platform attract each other’s users, thus reflecting derivative usage between them. We performed a randomized field experiment to test the proposed hypotheses. The results reveal that interface similarity, embeddedness, and synchrony of the app-platform interface design strengthen users’ grouping perception of the platform and its apps, thus enhancing platform-to-app forward derivative usage. Contrary to our expectations, we found that this strengthened grouping perception does not improve the app-to-platform backward derivative usage. These findings have crucial implications for the value of interface design in software platform ecosystems.
The Power of Identity Cues in Text-Based Customer Service: Evidence from Twitter
Authors: Gao Yang , Rui Huaxia , Sun Shujing
Published: September 2023

Text-based customer service is emerging as an important channel through which companies can assist customers. However, the use of few identity cues may cause customers to feel limited social presence and even suspect the human identity of agents, especially in the current age of advanced algorithms. Does such a lack of social presence affect service interactions? We studied this timely question by evaluating the impact of customers’ perceived social presence on service outcomes and customers’ attitudes toward agents. Our identification strategy hinged on Southwest Airlines’ sudden requirement to include a first name in response to service requests on Twitter, which enhanced customers’ perceived level of social presence. This change led customers to become more willing to engage and more likely to reach a resolution upon engagement. We further conducted a randomized experiment to understand the underlying mechanisms. We found that the effects were mainly driven by customers who were ex ante uncertain or suspicious about the human identity of agents, and the presence of identity cues improved service outcomes by enhancing customers’ perceived levels of trust and empathy. Additionally, we found no evidence of elevated verbal aggression from customers toward agents with identity cues, although a mechanism test revealed the moderating role of customers’ emotional states. Our study highlights the importance of social presence in text-based customer service and suggests a readily available and almost costless strategy for firms: signal humanization through identity cues.

Published: September 2023

QSAR models capable of predicting biological, toxicity, and pharmacokinetic properties were widely used to search lead bioactive molecules in chemical databases. The dataset’s preparation to build these models has a strong influence on the quality of the generated models, and sampling requires that the original dataset be divided into training (for model training) and test (for statistical evaluation) sets. This sampling can be done randomly or rationally, but the rational division is superior. In this paper, we present MASSA, a Python tool that can be used to automatically sample datasets by exploring the biological, physicochemical, and structural spaces of molecules using PCA, HCA, and K-modes. The proposed algorithm is very useful when the variables used for QSAR are not available or to construct multiple QSAR models with the same training and test sets, producing models with lower variability and better values for validation metrics. These results were obtained even when the descriptors used in the QSAR/QSPR were different from those used in the separation of training and test sets, indicating that this tool can be used to build models for more than one QSAR/QSPR technique. Finally, this tool also generates useful graphical representations that can provide insights into the data.
Switching Nanoscale Temperature Fields with High-Order Plasmonic Modes in Transition Metal Nanorods
Authors: Setoura Kenji , Tamura Mamoru , Oshikiri Tomoya , Iida Takuya
Published: September 2023

Metal nanostructures exhibit various plasmonic modes, including dipolar, quadrupolar, and hexapolar modes, depending on photo-irradiation conditions. In the present work, we numerically demonstrated that these high-order plasmonic modes can be used to switch nanoscale temperature distributions in plasmonic heating of a manganese (Mn) nanorod; the key feature of Mn is its low thermal conductivity. In general, when noble metal nanostructures are used for the plasmonic heating, nanostructure surface will be almost isothermal regardless of the order of the excited plasmonic modes, because of high thermal conductivities of noble metals: e.g. a themal conductivity of gold is 314 [W m−1K−1]. However, in contrast to noble metals, Mn possesses a significantly lower thermal conductivity of 7.8 [W m−1K−1]. Due to this lower thermal conductivity value, the distinct spatial characteristics of high-order plasmonic modes can be clearly transcribed into nanoscale temperature fields; this is achieved through the generation of polarization currents by the high-order plasmons within the nanorod. These findings strongly suggest that high-order plasmonic modes hold significant potential for advanced and precise manipulation of heat generation at the nanometer scale in the field of thermoplasmonics.
First-principles simulation of excitation energy transfer and transient absorption spectroscopy in the CP29 light-harvesting complex
Authors: Saraceno Piermarco , Sláma Vladislav , Cupellini Lorenzo
Published: September 2023

Abstract The dynamics of delocalized excitons in light-harvesting complexes (LHCs) can be investigated using different experimental techniques, and transient absorption spectroscopy (TA) is one of the most valuable methods for this purpose. A careful interpretation of TA spectra is essential for the clarification of excitation energy transfer (EET) processes occurring during light-harvesting. However, even in the simplest LHCs, a physical model is needed to interpret transient spectra, as the number of EET processes occurring at the same time is too large to be disentangled from measurements alone. Physical EET models are commonly built by fittings of the microscopic exciton Hamiltonians and exciton-vibrational parameters, an approach that can lead to biases. Here we present a first-principles strategy to simulate EET and transient absorption spectra in LHCs, combining molecular dynamics and accurate multiscale quantum chemical calculations to obtain an independent estimate of the excitonic structure of the complex. The microscopic parameters thus obtained are then used in EET simulations to obtain the population dynamics and the related spectroscopic signature. We apply this approach to the CP29 minor antenna complex of plants, for which we follow the EET dynamics and transient spectra after excitation in the chlorophyll b region. Our calculations reproduce all the main features observed in the transient absorption spectra and provide independent insight on the excited-state dynamics of CP29. The approach presented here lays the groundwork for the accurate simulation of EET and unbiased interpretation of transient spectra in multichromophoric systems.
Temperature-Dependent Spin-Driven Dimerization Determines the Ultrafast Dynamics of a Copper(II)-Bound Tripyrrindione Radical

Published: September 2023

Radicals and other open-shell molecules play a central role in chemical transformations and redox chemistry. While radicals are often highly reactive, stable radical systems are desirable for a range of potential applications ranging from materials chemistry and catalysis to spintronics and quantum information. Here we investigate the ultrafast properties of a stable radical system with temperature-dependent spin-tunable properties. This radical complex, Cu(II) hexaethyl tripyrrin-1,14-dione, accommodates unpaired electrons localized on both the copper metal center and on the tripyrrolic ligand. Two-dimensional electronic spectroscopy measurements of Cu(II) hexaethyl tripyrrin-1,14-dione were collected at room temperature and at 77 K. At room temperature, the molecules are present as monomers and have short, picosecond lifetimes. At 77 K, the molecules are present in a dimer form mediated by ferromagnetic and anti-ferromagnetic coupling. This reversible spin-driven dimerization changes the optical properties of the system, generating long-lived excitonic states.
Droplet tilings in precessive fields: Hysteresis, Elastic Defects, and Annealing
Authors: Molina Anton , Prakash Manu
Published: September 2023

Two-component Marangoni contracted droplets can be arranged into arbitrary two-dimensional tiling patterns where they display rich dynamics due to vapor mediated long-range interactions. Recent work has characterized the centered hexagonal honeycomb lattice, showing it to be a highly frustrated system with many metastable states and relaxation occurring over multiple timescales [Molina et al., PNAS, 2021, 18, 34]. Here, we study this system under the influence of a rotating gravitational field. High amplitudes are able to completely disrupt droplet-droplet interactions, making it possible to identify a transition between field-dominated to interaction-dominated regimes. The system displays complex hysteresis behavior, the details of which are connected to the emergence of linear mesoscale structures. These mesoscale features display an elasticity that is governed by the balance between gravity and long-ranged vapor-mediated attractions. We find that disorder plays an important role in determining the dynamics of these features. Finally, we demonstrate the ability to anneal the system by progressively reducing the field amplitude, a process that reduces configurational energy compared to a rapid quench. The ability to manipulate vapor-mediated interactions in deliberately designed droplet tilings provides a novel platform for table-top explorations of multi-body interactions.

Intraventricular septum rupture is a rare mechanic complication of myocardial infarction associated with high mortality. This case describes STEMI in recovered patient after COVID 19 associated pneumonia, which was complicated by ventricular septum rupture followed by cardiogenic shock. It was managed by percutaneous occluder implantation. The procedure was complicated by right ventricular wall rupture. Postmortem examination of myocardium showed the signs of inflammation infiltrate and myocyte necrosis, according to histopathological Dallas criteria diagnosis of COVID-19 associated myocarditis was established. The COVID-19 pandemic has contributed to increasing cardiovascular mortality. This is typically attributed to diminishing resources for timely and appropriate medical care, and patients late presentations for fear of contracting the infection. Cardiovascular complication of COVID-19 may be another contributing factor. Further research is needed to improve our understanding of the mechanisms and long-term sequelae of myocardium damage in COVID-19, to optimize treatment strategy and subsequent follow-up in such patients.
LOCAL DISTRICT CENTERS IN THE SETTLEMENT SYSTEM OF THE TVER REGION

Published: September 2023

Статья посвящена традиционной, но не особо популярной теме отечественной географии населения и населенных пунктов – изучению районных центров. Несмотря на реформирование муниципального устройства в России и замену муниципальных районов округами, название «районный центр» сохраняет свою актуальность и является общеупотребимым. Проводимые преобразования и отказ от двухуровневой системы муниципалитетов означают централизацию управления, что неизбежно ведет к возрастанию роли районных центров в жизни окружающей территории. На примере Тверской области проведена классификация современных райцентров по нескольким признакам. В основу легли людность центра, его административный статус, ЭГП, наличие межрайонных функций, оцененный экспертным путем уровень экономического развития. Итоговая группировка включила семь групп районных центров, пять – основных и две – дополнительных. Исследование показало сильные различия между «крайними» группами райцентров, обусловленные их разной ролью как центров расселения и развития Тверского региона.

The article is devoted to a special category of settlements – local district centers. Despite the reform of the municipal structure in Russia, the name «district center» remains relevant and is commonly used. The ongoing transformations and the rejection of the two-tier system of municipalities mean the centralization of management, which inevitably leads to an increase in the role of local district centers in the life of the surrounding territory. On the example of the Tver region, a classification of modern district centers was carried out according to several criteria. The population size of the center, its administrative status, geographical position, the presence of inter-district functions, and the level of economic development formed the basis of classification. The final grouping included seven groups of district centers, five - main and two - additional. The study showed strong differences between the «extreme» groups of district centers, due to their different roles as centers of settlement and development of the Tver region.

El osciloscopio es un equipo de medición ampliamente utilizado para visualizar señales, analizar fenómenos eléctricos que colabora en la verificación, depuración y solución de problemas múltiples campos. Este instrumento permite la visualización de señales eléctricas en el tiempo y así mismo la medición de las respectivas características de estas señales (por ejemplo: amplitud, valor pico a pico, valor promedio, periodo, frecuencia). En sus primeros acercamientos al osciloscopio, los estudiantes suelen presentar temor en su manipulación, debido a que su panel frontal ofrece una amplia cantidad de controles, a que es un instrumento al cual no se tiene amplio acceso convencionalmente, como sí puede ser un multímetro digital, y que debido a su costo prefieren limitar su manejo para evitar daños. Dado que es de gran importancia promover en los estudiantes de carreras de ingeniería tales como ingeniería electrónica, ingeniería eléctrica, ingeniería mecatrónica, redes y telecomunicaciones y otras más, habilidades para obtener la correcta visualización y así mismo realizar las mediciones con el osciloscopio e interpretar los resultados de esas mediciones, se desarrolló un objeto virtual de aprendizaje (OVA) que permite a los estudiantes manipular los controles de este equipo sobre un panel de control simulado. Esto permite que los estudiantes puedan explorar el equipo con anterioridad a las prácticas de laboratorio y también repasar lo aprendido en dichas prácticas, ya que este OVA les permite obtener realimentación en tiempo real sobre el uso de las diferentes opciones utilizadas para visualizar correctamente las señales y los resultados obtenidos en la medición. El desarrollo de este objeto virtual de aprendizaje hace parte de un proyecto colaborativo entre una universidad pública y otra privada, de forma que la validación de este material didáctico es realizada en diferentes contextos (provincia y capital).

Published: September 2023

Current methods for profiling DNA methylation require costly reagents, sequencing, and labor time. We introduce fragmentation at methylated loci and sequencing (FML-seq), a sequencing library protocol that greatly reduces all these costs. Relative to other techniques tested on the same human cell lines, FML-seq produces similar measurements of absolute and differential cytosine methylation at a fraction of the price. FML-seq enables inexpensive, high-throughput experimental designs for large-scale epigenetics research projects.

Published: September 2023

The primary aim of this paper is to present the key elements that characterise online course design, addressing the process of designing, implementing, and evaluating an online course for Bachelor’s degree students that focuses on developing their academic writing skills. These skills are essential for university students as they provide the knowledge necessary to express themselves effectively, analyse texts, think critically, cite correctly, and avoid plagiarism. Academic writing is also the foundation for responsible research practice. The Research Integrity Competency Profile Model, which includes four main areas, namely values and principles, research practice, publication and dissemination, and violations, was createdprior to the design of the course and the skills students need to acquire at the Bachelor’s level for successful academic writing were identified. A small private online course was carefully designed in 2020. It consisted of a variety of assignments, including interactive elements such as quizzes, videos, and work in international interdisciplinary groups. The participants of the course were 36 students from Slovenia, the Netherlands, and the Czech Republic. The course lasted four weeks and covered topics such as literature analysis, writing a research paper, avoiding plagiarism, paraphrasing, and citation styles, among others. The course was launched in 2021 for two consecutive instances. The participating students evaluated the course positively, describing the assignments as motivating, useful, and well-structured. However, they concluded that they need more practice in this area, and we suggest that a university course be established to provide all students with the necessary academic writing skills.

Published: September 2023

Government Upper Primary School Puracherry is situated in the Madayi educational district within the Kannur district of Kerala. The school comprises 322 students and 18 teachers, offering classes from 1st to 7th standard. During the Covid- 19 pandemic, the government declared lockdown measures, resulting in the closure of schools. During this period, "First Bell," an initiative of the General Education Department of Kerala, was launched on June 1, 2020, serving as an interim solution while state public schools remained closed. Throughout the academic year 2020-21, Government Upper Primary School Puracherry implemented numerous innovative programs aimed at ensuring that no student missed classes during the pandemic, all while monitoring the safe stay of children at home. The investigator intends to study the educational, economic, technological, and social aspects of the quality-sustaining practices of Government Upper Primary School Puracherry. The study sample includes 4 teachers, 4 parents, and 4 students from Government Upper Primary School Puracherry. The findings revealed that the majority of students and parents favored these qualitysustaining practices, with approximately 80% of children ensuring their access to classes. This study is limited to one school in Kerala, but its findings can benefit educationalists, curriculum developers, teachers, parents, and students in other schools across India.
Online instruction in the face of covid-19 crisis: An examination of early childhood and elementary teachers' practices
Authors: Jale Aldemir , Jambunathan
Published: September 2023

The COVID-19 pandemic had significant impacts on every facet of society, and its implicit effects on education were felt most by younger learners. In this instrumental case study, the online remote teaching experiences of early childhood and early elementary teachers in a school district located in the Northeastern U.S. were surveyed. The results revealed that the teachers initially struggled to adapt to a multitude of technological tools and software offered, all the while trying to maintain a human connection with their students. The teachers encountered several issues during online remote learning, such as the availability of reliable internet and technology, students' home environment conditions, and a lack of knowledge regarding the pedagogical use of technology. The administrative and peer support helped them cope with the difficulties they experienced. The information from the study could be used to build a better alternative teaching infrastructure.
Investigating Rupture Cascades on the Alpine Fault and Marlborough Fault System Using Lacustrine Paleoseismology
Authors:   , Matheson Alexandra
Published: September 2023

Rupture cascade describes a pattern of earthquake occurrence whereby a high-magnitude earthquake on one fault hastens the occurrence of failure on nearby faults, potentially resulting in sequences of large earthquakes on timescales of years to decades. Earthquake simulations and paleoseismic data suggest that rupture cascades may be a prevalent behaviour of the interconnected Alpine Fault and Marlborough Fault System (A-MFS), and that large earthquakes on the Alpine Fault may trigger rupture cascades on the Marlborough Fault System (MFS). However, to date there has not been a robust test of the temporal sequencing of large earthquakes on the A-MFS. Although major earthquakes on the central Alpine Fault are precisely dated, paleoearthquake ages on the MFS span centuries, precluding identification of earthquakes that occurred within years to decades of each other. More precise paleoearthquake chronologies are required from the MFS to determine if rupture cascades triggered by the Alpine Fault have occurred in the past. Lake sediments may provide suitable paleoseismic records because they can provide long, continuous records of earthquakes that have decadal temporal precision.

This thesis applied a lacustrine paleoseismology approach to Lake Tennyson, on the western MFS, to test the hypothesis that large earthquakes on the central Alpine Fault can trigger rupture cascades on the MFS. A paleoseismic record was developed using sedimentology, seismic survey data, and geochemical and paleo-ecological analyses, and dated with decadal precision using numeric age control (210Pb and 14C) in conjunction with Bayesian age modelling. The ages of eight earthquakes, spanning the last ~2000 years, were then compared with lacustrine paleoseismic records from the central Alpine Fault and two other lake sites on the western MFS to investigate spatio-temporal patterns of rupture on the A-MFS. Results showed that at least two of the last five central Alpine Fault earthquakes were followed within a maximum of 60 years by an earthquake on a western Marlborough fault, supporting the hypothesis that the Alpine Fault rupture can trigger rupture cascades in the MFS. The results from this research demonstrate the usefulness of lacustrine paleoseismology for investigating spatio-temporal patterns of rupture across the A-MFS, and future research should use more lake sites from the wider MFS, in conjunction with quantitative fault source modelling, to better understand the behaviour of this complex fault system.
Spatial Distribution and Influencing Factors of Urban Shrinkage from the Perspective of Factor Flow - A Case Study of National Urban Agglomerations
Authors: Sun Yuheng , Ma Zhifei , Huang Huan
Published: September 2023

This paper examines national urban agglomerations by taking factor flows as the focal point as the researchsubject. By dividing the stages of urban agglomeration development, a comprehensive framework of urban shrinkage is constructed, encompassing economic, population, and social shrinkage. The study explores the spatial distribution characteristics of urban shrinkage during different stages of urban agglomeration and investigates the influencing factors using a geographic detector model. The findings reveal that urban shrinkage within urban agglomerations is widely spread, predominantly in peripheral areas. During the diffusion stage, urban shrinkage is scattered, with population shrinkage concentrated in peripheral regions, economic shrinkage concentrated on old industrial cities, and social shrinkage concentrated on the northeast. The outcomes of the geographic detector model indicate that traffic flow, capital flow, information flow, node importance, network connectivity, government investment, openness, and environmental regulations all play significant roles in shaping the spatial distribution of urban shrinkage.

O artigo apresenta as considerações dos alunos ao final do 9º ano do ensino fundamental, sendo um ano depois investigados, cursando as 1ª séries do NEM de uma escola da rede estadual de Educação Básica de Santa Catarina. A investigação buscou analisar as expectativas e realidades dos alunos para o NEM, apreender as aspirações sobre o processo de ensino e aprendizagem dos Componentes Curriculares Eletivos, identificar o ensejo dos alunos em relação a aprendizagem e desenvolvimento no Projeto de Vida e analisar as intenções de frequentar um curso, ingressar no Jovem Aprendiz ou em um emprego durante o NEM. Em suma, o objetivo central da pesquisa propôs a análise das expectativas e realidade vivenciada pelos alunos no NEM de uma escola da rede estadual de Educação Básica de Santa Catarina. Como procedimento de análise optou-se pela Análise de Conteúdo (BARDIN, 2011), por meio de um questionário com perguntas abertas que registrou os relatos de 83 alunos no 9º ano, destes, 46 permaneceram matriculados na escola na 1ª série do NEM. As respostas apontaram sobre o desenvolvimento pessoal e emocional dos alunos, a insatisfação a respeito da metodologia das aulas no NEM, a aspiração de realizarem cursos e conseguirem um emprego.

Introduction. The article summarizes the experience of the teachers of the Department of Biogeography of Lomonosov Moscow State University, accumulated during remote teaching and organizing field practices for students under restrictive measures during the COVID-19 pandemic in 2020-21. The sudden introduction of remote learning required an urgent adaptation of academic programmes, the modification of existing teaching technologies to the new format, and a rapid restructuring of the educational process.

Materials and Methods. The use of a new textbook with presentations and video materials, archival materials, educational and methodological and scientific publications, video recordings describing characteristics of individual plant and animal species, the structure and composition of particular phytocenoses, issues of their protection and anthropogenic transformation. Published materials on the biological and landscape diversity of Moscow City and the Moscow Region and on the specifics of anthropogenic transformation in this territory and ongoing conservation measures are used.

Results. Determination of the methodological basis and development of principles for organizing and conducting classes and field practices in the context of anti-COVID-19 restrictions and analysis of the experience gained in order to determine the possibility of its application in similar circumstances.

Discussion and Conclusions. In the context of distance learning, approaches to the demonstration of visual materials during classes were changed, the presentations that replaced the explanations of teachers in the exposition of the Museum of Geography of Moscow State University (the main training ground for practical work on the course "Ecology with the basics of biogeography") were created. Field practices were reduced, moved to new locations and reformatted in terms of approaches to the study of flora, geobotanical profiling and writing a report. The experience gained was positive and the work results received high marks in the surveys of students and teachers. The developed approaches can be used in case of new restrictions, as well as when working with people with disabilities.

In the article under consideration, an assessment of meat productivity and the biological value of the meat of local Tuvan goats is given. The object of research were local Tuvan goats at 8, 12, 18 months of age. Upon reaching this age, a control slaughter of goats was carried out, as well as carcass cutting in accordance with GOST 31777 - 2012. It was established that at the age of 18 months the carcasses of goats were full-fleshed witha fairly high content of muscle and adipose tissue, and the meat was characterized by high biological value.
