Authors: Будищева Н.Ф. , Яковлева К.М.
Published: July 2024

Статья посвящена вопросу о происхождении якутской косы-горбуши на материале мастеров с. Кэнтик Верхневилюйского улуса, который является одним из традиционных центров железоделательного производства на территории Якутии. Задачи исследования: 1) определить технологию использования косы; 2) изучить структуру косы и сравнить с косой-литовкой; 3) исследовать историю происхождения косы-горбуши. Систематизирован обширный опубликованный и неопубликованный материал о косе-горбуше. В научный оборот введены материалы из фондов историко-этнографического музея «Чап уустара» с. Кэнтик Верхневилюйского улуса, а также полевые материалы автора, собранные во время экспедиций в 2021‒2022 гг. В основном использованы данные, собранные в местности Кюрсюр Кэнтикского наслега на берегу р. Тонгуо и местности Кууну. Полевой материал собран посредством фото- и видеофиксации, включенного наблюдения, экспертного интервьюирования. Описаны две косы-горбуши из музейного фонда, проведено сравнение с косой-литовкой. На основе музейных материалов и полевого материала авторы приходят к выводу, что коса-горбуша не была заимствована из русской культуры, опровергая тем самым представления о том, что якуты не знали сенозаготовку. Авторы опираются на труды А.И. Гоголева о происхождении якутов и их традиционной культуры, в частности об историко-культурных связях якутов с современными народами Южной Сибири.

The article is dedicated to the origin of the Yakut hunchback scythe, based on material from the masters in the village of Kentik in the Verkhnevilyuysky district, which is one of the traditional centers for ironworking in Yakutia. Research objectives: 1. To determine the technology used to make the scythe. 2. To examine the structure of the scythe in comparison to the scythe-cast. 3. To investigate the origins of the hunchback scythe. Extensive published and unpublished materials on the hunchback scythe have been systematized. Materials from funds of the “Chap Uustara” historical and ethnographic museum, the village of Kentik, Verkhneviluysky district, as well as field materials collected by the author during expeditions in 2021-2022 have been put into scientific circulation. Data collected from the Kursuur area of Kentik nasleg, on the side of Tonguo River, and Kuunu area, were mainly used. Field material was collected through photo and video recording, observation, and expert interviews. Two hunchback scythes are described from museum funds, and a comparison is made with the scythe-cast. Based on museum and field materials, the authors conclude that hunchback scythe did not come from Russian culture. This refutes the idea that Yakuts did not know how to harvest hay. The authors rely on the works of A.I. Gogolev about the origin of the Yakuts and their traditional culture, in particular about the historical and cultural ties of the Yakuts with the modern peoples of Southern Siberia.

Authors: Роббек Л.В.
Published: July 2024

При лексикографировании языка якутского эпоса, который является специфичной формой национального языка, ортодоксальные словарные методы в преобладающем большинстве случаев оказываются непрофильными. Статья посвящена разработке оптимальной модели дефиниций в словаре языка олонхо. В результате проведенного исследования структурирован стандарт словарной дефиниции, адаптированный для рационального раскрытия самобытного значения устно-поэтического слова. Предложенная структура дефиниции состоит из базисной и комментирующей частей. При этом в базисной части дефиниции содержится общее определение вокабулы, а фольклорная коннотация раскрывается в комментирующей части.

The article is devoted to solving the problem of forming a certain structure of a dictionary definition that can sufficiently reveal the connotative meaning of words functioning in the language of the heroic epic Olonkho. The problematic nature of the issue under consideration has many roots and is associated with the prerequisites for the morphogenesis of the artistic system of folk poetic speech, the concepts of “folklore language”, “Olonkho language”, as a specific form of the national language. The subject of discussion touches on the problem of studying the origins of the development of the art of depicting the oral poetic word, denoting almost all the factors associated with the emergence of the phenomenon of “language of oral poetic creativity”. The problem is complicated by the fact that in the practice of folklore lexicography there is no tendency to use methodologies that take into account the peculiarities of the language systems of Turkic-speaking peoples. The article is intended to eliminate the existing white spot in the specified area. The purpose of the article is to conduct an integrative analysis of the lexical-semantic features of the Olonkho language, and to develop the basic principles for the formation of dictionary definitions in the Olonkho language dictionary. The study was conducted on the material of the olonkho text “Nyurgun Bootur the Swift” by K. Orosin as a result of the analysis, the structure of the definition in the Olonkho language dictionary was determined, consisting of a basic and commentary part. The function of revealing folklore connotation is assigned to the commentary part of the definition. The presented scheme for compiling a dictionary definition can be applied to all units of lexicographic description: stable verbal complexes and single lexemes.

Published: July 2024

В статье предложен алгоритм построения структуры данных на основе ограниченного сверху диапазона натуральных чисел. Эта структура позволяет осуществлять факторизацию чисел из данного диапазона в худшем случае за логарифмическое время и проверку на простоту за константное. Сопутствующим эффектом построения предложенной структуры является нахождение всех простых чисел в заданном диапазоне и представление их в виде двусвязного списка. В работе приведена оценка асимптотической сложности всех предложенных алгоритмов, в том числе показано, что асимптотическая сложность построения предложенной структуры не превышает линейную. Предложен подход к использованию построенных алгоритмов и структуры данных для реализации длинной арифметики в факторизованном виде. Рассмотрен класс прикладных задач, для решения которых целесообразно использовать длинную арифметику в факторизованном виде с предложенным алгоритмом факторизации.

In the article an algorithm for constructing a data structure is given which based on a range of natural numbers limited from above. This structure allows factorization of numbers from a given range in the worst case in logarithmic time and checking for primality in constant time. A side effect of constructing the proposed structure is to nd all prime numbers in a given range and represent them as a doubly linked list. The paper provides an estimate of the asymptotic complexity of all proposed algorithms, including showing that the asymptotic complexity of constructing the proposed structure does not exceed linear. An approach to using the constructed algorithms and data structure to implement long arithmetic in factorized form is proposed. A class of applied problems is considered, for the solution of which it is advisable to use long arithmetic in factorized form with the proposed factorization algorithm.
Precise estimation of activation energies in gas-phase chemical reactions via artificial neural network
Authors: Cao Guo-Jin , Lu Sheng-Jie
Published: July 2024

Various machine learning (ML) models are presented in this study, aiming to forecast the barrier heights (BHs) of gas-phase chemical reactions. The input features utilized in six distinct models were obtained from the structural and thermodynamic attributes of molecules, encompassing enthalpy, topological indices, and Morgan fingerprints derived from SMILES, using a dataset consisting of 5040 decomposition reaction records sourced from the Gas Phase Organic Chemistry database. Evaluating the effectiveness of the models included the application of essential metrics such as coefficient of determination, mean absolute error, and root mean square error. It is worth noting that artificial neural networks outperform the other models in this regard. Then we utilized Morgan fingerprints of different dimensions as inputs for the neural network models and conducted training with varying numbers of hidden layers. This endeavor led to slight improvements in the performance of gas-phase decomposition reactions, resulting in an average determination coefficient of 0.965 and a mean absolute error of 0.079 eV. Subsequently, the model was subjected to retraining using a comprehensive dataset comprising a wide range of chemical reactions. The results indicate that the artificial neural network approach has the capacity to generalize and adjust to a wider range of chemical reactions.
Highly Tolerant Living/Controlled Anionic Polymerization of Dialkyl Acrylamides Enabled by Zinc Triflate/Phosphine Lewis Pair
Authors: Akita Riki , Matsuoka Shin-ichi
Published: July 2024

Living polymerizations of polar vinyl monomers have been successful for decades. However, they still suffer the following challenges: fast propagation, air/moisture tolerance, and negligible side reactions even at elevated temperatures. Here, we developed an unprecedented polymerization that overcomes these limitations using a Lewis pair catalyst. The anionic polymerization of dialkyl acrylamides proceeded in a living/controlled matter using Zn(OTf)2/PPh3 within a wide temperature range of 25–100 °C for short times (1–10 min) even under open-air conditions. The recovery and reuse of Zn(OTf)2 without loss of polymerization activity were observed to be possible. The polymerization was retarded by excess Zn(OTf)2, additive methanol, and water, indicating equilibriums of the propagating species with them. The putative propagating zinc triflate-ate complex was tolerant to the protic additives and significantly selective for the propagation.
Commercially available carrageenans show broad variation in their structure, composition, and functionality
Authors: Hale Julia , Gerhäuser Julian , Gaukel Volker , Wefers Daniel
Published: July 2024

Carrageenans are polysaccharides from red algae which are widely used as food additives and in other applications. Their structure is often described by different disaccharide repeating units, although it was already demonstrated that reality is more complex. In many studies, commercial carrageenans were used to establish structure function relationships, but a structural and compositional analysis was rarely conducted. Therefore, the aim of our study was to systematically and comprehensively characterize a broad collection of commercial carrageenans with different specifications from different manufacturers. For a more detailed characterization, an analytical approach based on partial enzymatic hydrolysis in combination with HPLC-MS and HPSEC-RI was developed and applied. Furthermore, rheology was used to gain detailed insights into the functionality of selected samples. Our results demonstrate that significant structural variation can be observed for commercial carrageenans. The samples contained different cations and the carrageenan type specified by the manufacturer did not always represent the structure of the corresponding polysaccharides. This was especially true for λ-carrageenans: Of the six commercial samples analyzed, none contained structural elements from the λ-type. Instead, the corresponding carrageenans contained κ-, ι- and ν-units. The application of the developed enzymatic-chromatographic approach showed that different hybrid carrageenans are present. In addition, the rheological analysis of the commercial carrageenan samples showed clear differences in the gelling properties upon calcium addition which could influence their behavior in different applications. Our results demonstrate that before an investigation of structure-function relationships, commercial carrageenan samples should be analyzed for their structure and composition. We also showed that the enzymatic-chromatographic approach described in this study is well suited for this purpose.

Published: July 2024

In conventional photo-induced polymerization strategies, the active species that initiate the reaction tend to be exogenous radical species. Inspired by photo-induced cycloaddition reactions, in this study we investigated photo-induced polymerization from the perspective of energy transfer processes. Utilizing low-energy, highly reactive triplet species of olefin molecules as energy acceptors, a polymerization strategy without the need for exogenous active components was developed. Triplet species from various sources were able to induce polymerization, demonstrating the excellent versatility of this strategy. The reaction mechanism was thoroughly investigated with controlled experiments and spectroscopic methods using thiochromanone as a template. It was clearly established that the key to polymerization is an active triplet species rather than a conventional radical species. As a result, the findings of this study stimulate further discussion on the role of monomers in photo-induced polymerization.
CO2 activation on pristine and Cu-decorated ψ-graphene and its hydrogenated forms: A DFT(D)+ U Study
Authors: Kumar Kamal , de Leeuw Nora , Adam Jost , Mishra Abhishek Kumar
Published: July 2024

Research into novel materials with tailored properties is essential to improve CO2 adsorption and activation, a fundamental preliminary phase in catalytic CO2 conversion processes. Here, we have employed density functional theory-based calculations to investigate CO2 activation over the pristine and Cu-decorated carbon-based two-dimensional material ψ-graphene and its hydrogenated forms, i.e. ψ-graphone (half hydrogenated) and ψ-graphane (fully hydrogenated). ψ-graphene is a metallic allotrope of graphene containing 5-6-7 membered carbon rings. Our study found exothermic binding of CO2 at all three materials (for both pristine and Cu-decorated materials), indicating spontaneous physisorption. The presence of a single Cu atom plays a significant role in increasing the activity of ψ-graphene towards CO2 activation. By decorating ψ-graphene with Cu atoms, the adsorption energy at ψ-graphene increases about three times, whereas no significant variation is observed on ψ-graphone and ψ-graphane sheets. We used Bader charge analysis and electronic density of states plots to further quantify the nature of the interaction between CO2 and these materials.

Authors: Panesar Divyansh , Civil Ian
Published: July 2024

introduction: Intentional physical self-injury (IPSI) is a pressing health challenge and there is little awareness of injury patterns, management and outcomes. This study examines IPSI’s epidemiological and clinical aspects in one major Auckland hospital, highlighting demography, injury patterns and implications for clinical practice and prevention. methods: Using Auckland City Hospital Trauma Registry data, a retrospective, descriptive study was conducted covering adult patients admitted from January 2015 to December 2019. It assessed demographic characteristics, injury patterns and outcomes, using Mann–Whitney U tests, Fisher’s exact tests and Chi-squared tests. results: Among 137 IPSI admissions, 92 (67%) required surgery, and 24% experienced post-operative complications. Major trauma was identified in 39 (28.5%) admissions. Discharge destinations varied, with only 64 (47%) patients returning home unassisted. Injury severity did not significantly vary across sex, age or injury event location. Major injuries often resulted from falls (19 of 39) and minor injuries from lacerations/stabs (73 of 98). conclusions: IPSI represents a significant challenge to Auckland health services, with a notable burden of care. The study highlights the need for targeted interventions to reduce the incidence of IPSI and improve outcomes. It underscores the importance of multidisciplinary approaches to care, integrating surgical, mental health and rehabilitative services.
Graphical modeling of additive color mixing. Analyses of electromagnetic effects as colors of the vision analyzer
Authors: Ignatov I. , Popova T.P.
Published: July 2024

The human visual analyzer is a high form of evolution. Some jellyfish can distinguish light and dark objects with sensitive cells. Squids, octopuses, and nautiluses from Cephalopods family have eyes with which they can see objects. Visual information is processed in the brain. In fishes, the visual analyzer evolved. Fishes living below 100 m depth inhabit a world with blue light. The authors consider the evolution of vision in these fishes due to the lowest absorption of blue and violet colors of electromagnetic waves from the optical spectrum. Subsequently, on land, in humans vision evolved towards the green color. Green is the most prevalent color on the land. In humans, three light-sensitive cones evolved – S, M, and L. S cones are most sensitive to blue, M – to green, and L – to red color in the spectrum. Some humans retain sensitivity of S to genetic changes and disorders. Additive color mi­xing is a high form of color perception in humans. The additive mixing of different colors achieves a new color in the human visual analyzer. Remarkably, different individuals perceive observed images in varying manners. Mixing neighboring colors on the spectrum gives one, two, or three colors. This process is estimated using graphical modeling. The graphical modeling with two colors allows for the creation of additive colors. One, two, or three additive colors can be obtained. The production of colors results from the light sensitivity of S, M, and L cones. An analysis that phy­sically demonstrates the mixing of green and red colors, resulting in the colors yellow or orange. When blue and red are mixed, the resulting colors are green, yellow, and orange is proposed. The additive mixing of blue and yellow gives green. The subjective nature of visual perception, influenced by the viewer’s heightened sensitivity to one of the colors, beco­mes evident in the presence of two colors. Notably, when the background is violet, the sensitivity of the blue cones diminishes.

The effect of niobium carbide coating on wear behavior of grey cast iron via thermo-reactive diffusion process
Authors: Yakut Rifat
Published: July 2024

Wear is the limit for grey cast iron (GCI), which is utilized extensively in today’s industries. Coating the surface of a material can enhance its ability to withstand wear. In this study, thermo-reactive diffusion (TRD) process was used to coat the surface of grey cast iron with niobium carbide (NbC). The coatings were applied for 2, 4 and 6 hours at 950ºC and 1050ºC. The coated samples were subjected to metallographic examination to investigate the microstructure of the coating zone. For this purpose, optical microscopy examinations were carried out. Microhardness tests were carried out to assess the mechanical properties of the samples. The coated surfaces were analyzed using energy-dispersive X-ray spectrometry (EDS), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Wear tests were carried out on the coated surfaces to measure the volumetric wear loss, the wear rate and the changes in the coefficient of friction. Coating thickness rose as furnace waiting time increased, according to optical microstructures of coated surfaces. The hardness of the coated surfaces increased with a longer coating duration. Depending on the duration and temperature of the coating process, the layer thickness ranged from 6 to 52 µm. The lowest microhardness and the highest microhardness values of the coatings were determined at 950ºC for 2 hours and at 950ºC for 6 hours, respectively. Compared to the uncoated samples, the coated samples had a 6-9 times higher hardness value. In the abrasion tests, the loss of wear volume increased with increase in load.

Published: July 2024

Due to the high energy consumption of refrigerated display cabinets used in supermarkets, a life cycle cooling performance analysis to increase energy efficiency and reduce environmental impacts is the main subject of this study. It also emphasizes the need for cabinets that consume less energy and provide environmentally friendly working conditions. The Life Cycle Climate Performance (LCCP) of the two refrigerants R290 and R449-A was evaluated using measured data to compare the environmental impact of the refrigerants over the entire fluid and equipment life cycle, including energy consumption. Both vapor-compressed cooling cycles were thermodynamically modeled with the parameters taken from the experiments and the efficiency of system was calculated by using the EES software. The results show that the cabinet using R290 has lower compressor power utilization. The COP of the R290 system increased by 13% compared to the R449A system. The total daily energy consumption was also significantly lower for the R290 system. The energy efficiency index provides a standardized metric that can be used to compare the performance of different cooling systems. In this study, the energy efficiency index value was 17.3 points lower for the R290 system, indicating higher energy efficiency. The energy classes are “E” for the R449-A system and “C” for the R290 system, with the R290 system two classes higher in terms of energy class labeling. The EEI value of the system with R290 refrigerant has been reduced by 33% in comparison with the system with R449A refrigerant. The system using R290 refrigerant achieved a 33% reduction in energy consumption compared to the system using R449A refrigerant. The study also assessed the life cycle climate performance of the two systems. It was found that the R449-A system emits 19032.45 kg CO2e more over its lifetime compared to the R290 system. This was attributed to the relatively high global warming potential and energy consumption of R449-A refrigerant. However, when considering safety (flammability), it was concluded that R-449A has a lower environmental impact than R-290.

La fiabilidad es un aspecto crítico en las predicciones de inteligencia artificial no cubierto por la mayoría de redes neuronales. Al contrario, las redes neuronales bayesianas (BNN) ofrecen una solución permitiendo calcular métricas de incertidumbre junto a sus predicciones, a cambio de aumentar el coste de la inferencia. Este trabajo optimiza dicho proceso desarrollando una extensión personalizada de bajo coste y consumo para la arquitectura RISC-V.

Con el fin de estudiar una emulsión de un material de cambio de fase (PCM) en agua para su uso como fluido caloportador en un intercambiador de calor, se ha diseñado un banco de ensayos ubicado en la nave 2 del edificio Betancourt de la EINA.
La instalación consta de tres circuitos: uno para la emulsión, otro para agua fría, y otro para agua caliente. Se empleará un intercambiador de placas para estudiar la transferencia de calor entre la emulsión PCM y agua, realizando un ensayo de calentamiento con agua caliente y otro de enfriamiento con agua fría.
Se ha optimizado la disposición de los circuitos para minimizar su recorrido y reducir la pérdida de carga.
Inicialmente, se validarán los resultados experimentales con un intercambio de calor entre agua-agua, y posteriormente se probará experimentalmente el intercambio emulsión PCM-agua.

Unsupervised Learning of Disentangled and Interpretable Representations of Material Appearance
Sin mundo: poética globales del espacio fronterizo.
Authors: Matas Pons Àlex
Published: July 2024

La voluntad de conocer lo que llamamos mundo se tradujo en un esfuerzo imaginativo por el que un supuesto todo reunía sus partes y englobaba sus particularidades. La historiografía ilustrada europea combinó esta dialéctica entre lo universal y lo particular con otra dialéctica entre lo geográfico y lo histórico. Logró así justificar su política y económica al enlazar un hipotético centro geográfico occidental con el progreso político, el desarrollo científico y el refinamiento cultural. Una vez agotada la narrativa de dicha imaginación, desde el ámbito estético-político surgen dos alternativas. La primera opción está relacionada con el orden postsoviético y promovería la imaginación del “demasiado mundo” mediante el “comunismo literario”, a partir sobre todo de las propuestas de Jacques Rancière y Jean-Luc Nancy. La segunda opción se desmarcaría del cosmopolitismo retórico y promovería la imaginación cosmopolítica del sin mundo para pensar una hospitalidad literaria universal, sin límites ni restricciones.

Effective local government asset management is critical for the efficient operation and sustainability of public institutions regarding their responsibility and otonomy given by the central government of Indonesia. On local government level, Regional Development Planning Office (Bappeda) is responsible as asset managers on province level. This study evaluates the management of regional assets at the Bappeda Office of West Sulawesi Province. Data collected through survey and interview with the office representatives and employee, supplemented by literature analysis of Domestic Affairs Regulation Number 19 Year 2016 to evaluates the policy implementation in the office. Data suggest that current activities or policy implementation in the office are alligned as the national policy standards. Core acts in the office includes planning – budgeting, procurement, utilization, optimization, security – maintenance, assessment, transfer, disposal, deletion, administration, guidance – supervision – control, and compensation – sanctions. The practices align with the Ministry of Domestic Affairs Policy, ensuring correct and effective implementation. Out of 100, we scored 58 - 59 to the current conformity level at Bappeda office. Some challenges remain with end-users, as some desire to personally own the official vehicles, occasionally breaching the rules, ownership, disposal, etc. The study underscores the importance of following established asset management cycles and regulations for effective asset utilization and maintenance, while highlighting the need for strategies to improve user compliance.

Growth-stimulating properties of Bacillus amyloliquefaciens B-11265 and Bacillus aryabhattai B-13192 strains were studied, and the possibility of their co-cultivation for activity intensification was evaluated. The strains under study were found to be able to synthesize indolyl-3-acetic and gibberellic acids, siderophores: B. amyloliquefaciens B-11265 in the amount of 5.23 µg/ml, 1.05 mg/ml, 46.15%; B. aryabhattai B-13192 – 3.07 µg/ml, 0.84 mg/ml, 35.50%, respectively. The research results showed that the strains were biocompatible and did not inhibit each other's development, allowing them to be included in the same consortium. Joint cultivation of the strains showed that the ratio of microorganisms in the nutrient substrate has a significant effect on the yield of the target substances. At the ratio of B. amyloliquefacien and B. aryabhattai 1 : 1, inhibition of indolyl-3-acetic acid synthesis was observed; ratios of 2 : 3 and 3 : 2 led to a decrease in gibberellic acid production. It was found that three (B. amyloliquefacien) to one (B. aryabhattai) was the optimal ratio to increase the yield of the target substances compared to the average values characteristic of individual strains. In this variant, the synthesis of growth-stimulating substances by the consortium was: indolyl-3-acetic acid – 5.31 μg/ml, gibberellic acid – 1.23 mg/ml, siderophores – 51.27%. The results obtained indicate the high potential of the engineered consortium for agricultural applications. However, in order to develop a growth-stimulating preparation based on it, it is necessary to conduct a number of additional studies aimed at investigating the effect of the strain on agricultural crops in laboratory and field experiments.
