Undervalued Spiny Monkey Orange (Strychnos spinosa Lam.): An Indigenous Fruit for Sustainable Food-Nutrition and Economic Prosperity
Authors: Omotayo Abiodun Olusola , Aremu Adeyemi Oladapo
Published: December 2021

Strychnos spinosa Lam. is among the top nutrient-dense indigenous fruit species that are predominant in Southern Africa. It is a highly ranked indigenous fruit based on the nutrition and sensorial properties, which make it an important food source for the marginalized rural people. On the basis of the high vitamin C, iron, and zinc content, it has the capacity to improve the food- nutrition and the socioeconomic status of individuals, especially those in the rural areas of the developing nations. The nutritional composition of Strychnos spinosa compare favorably with many of the popular fruits, such as strawberries and orange. Additionally, Strychnos spinosa has antioxidant activity similar to well-known antioxidant fruits, which keeps it in the class of the popular fruits, giving it added nutrition–health-promoting benefits. In order to improve the availability of Strychnos spinosa, more research on the domestication, processing, preservation, value chain, and economic potential need to be further explored. Therefore, we recommend more concerted efforts from relevant stakeholders with interest in Strychnos spinosa fruit production as a possible sustainable solution to food shortage, food-nutrition insecurity, malnutrition, and austerity, mainly in the rural communities of the developing countries.

Published: December 2021

One of the major challenges currently in the field of material science is finding natural alternatives to the high-performing plastics developed in the last century. Consumers trust synthetic products for their excellent properties, but they are becoming aware of their impact on the planet. One of the most attractive precursors for natural polymers is tannin extracts and in particular condensed tannins. Quebracho (Schinopsis balansae) extract is one of the few industrially available flavonoids and can be exploited as a building block for thermoset resins due to its phenol-like reactivity. The aim of this study was to systematically investigate different hardeners and evaluate the water resistance, thermal behavior, and chemical structure of the quebracho tannin-based polymers in order to understand their suitability as adhesives. It was observed that around 80% of the extract is resistant to leaching when 5% of formaldehyde or hexamine or 10% of glyoxal or furfural are added. Additionally, furfuryl alcohol guarantees high leaching resistance, but only at higher proportions (20%). The quebracho-based formulations showed specific thermal behavior during hardening and higher degradation resistance than the extract. Finally, these polymers undergo similar chemistry to those of mimosa, with exclusive reactivity of the A-ring of the flavonoid.

Published: December 2021

The use of ultraviolet radiation (UV) technology for the crosslinking of acrylic pressure-sensitive adhesives (PSA) is the one of various crosslinking methods, being the alternative to the conventional crosslinking process of solvent-based acrylic systems. It also requires a photoinitiator to absorb the impinging UV and induce photocrosslinking. As previously mentioned, a photoinitiator is one of the important and necessary components in UV-inducted crosslinking of acrylic pressure-sensitive adhesives. The activity of multifunctional conventional saturated photoinitiators of type I and type II, especially benzophenone-based in the photoreactive UV-crosslinkable acrylic PSA was described. The effect of the multifunctional type-II photoinitiators on the acrylic PSA, such as tack, peel adhesion and shear strength were summarized.

Zero tillage is an important pathway to sustainable intensification and low-emission agriculture. However, quantifying the extent of zero tillage adoption at the field scale has been challenging, especially in smallholder systems where field sizes are small and there is limited ground data on zero tillage adoption. Remote sensing offers the ability to map tillage practices at large spatio-temporal scales, yet to date no studies have used satellite data to map zero tillage adoption in smallholder agricultural systems. In this study, we use Sentinel-2 satellite data, random forest classifiers, and Google Earth Engine to map tillage practices across India’s main grain producing region, the Indo-Gangetic Plains. We find that tillage practices can be classified with moderate accuracy (an overall accuracy of 75%), particularly in regions with relatively large field sizes and homogenous crop management practices. We find that models that use satellite data from only the first half of the growing season perform as well as models that use data throughout the growing season, allowing for the creation of within-season tillage maps. Finally, we find that our model can generalize well through time in the western IGP, with reductions in accuracy of only 5–10%. Our results highlight the ability of Sentinel-2 satellite data to map tillage practices at scale, even in smallholder systems where field sizes are small and cropping practices are heterogeneous.
AAU-Net: Attention-Based Asymmetric U-Net for Subject-Sensitive Hashing of Remote Sensing Images
Authors: Ding Kaimeng , Chen Shiping , Wang Yu , Liu Yueming , Zeng Yue , Tian Jin
Published: December 2021

The prerequisite for the use of remote sensing images is that their security must be guaranteed. As a special subset of perceptual hashing, subject-sensitive hashing overcomes the shortcomings of the existing perceptual hashing that cannot distinguish between “subject-related tampering” and “subject-unrelated tampering” of remote sensing images. However, the existing subject-sensitive hashing still has a large deficiency in robustness. In this paper, we propose a novel attention-based asymmetric U-Net (AAU-Net) for the subject-sensitive hashing of remote sensing (RS) images. Our AAU-Net demonstrates obvious asymmetric structure characteristics, which is important to improve the robustness of features by combining the attention mechanism and the characteristics of subject-sensitive hashing. On the basis of AAU-Net, a subject-sensitive hashing algorithm is developed to integrate the features of various bands of RS images. Our experimental results show that our AAU-Net-based subject-sensitive hashing algorithm is more robust than the existing deep learning models such as Attention U-Net and MUM-Net, and its tampering sensitivity remains at the same level as that of Attention U-Net and MUM-Net.
Experimental Investigations of Effective Thermal Conductivity of the Selected Examples of Steel Porous Charge
Authors: Wyczółkowski Rafał
Published: December 2021

In many cases of heat treatment of steel products, the heated charge has a porous structure. The examples of such charges include bundles of long steel components e.g., bars. The basic thermal property of the charge in this form is effective thermal conductivity kef. This paper presents the results of experimental examinations of effective thermal conductivity of the porous charge, which is composed from various types of steel long components. Due to the specific nature of the samples, a special measurement stand was constructed based on the design of a guarded hot plate apparatus. The measurements were performed for sixteen different samples across a temperature range of 70–640 °C. The porosity of the samples, depending on the type of components used, ranged from 0.03 to 0.85. Depending on these factors, the effective thermal conductivity ranged from 1.75 to 8.19 W·m−1·K−1. This accounts for 0.03 to 0.25 of the value of thermal conductivity of the solid phase of the charge, which in the described cases was low-carbon steel. It was found that the effective thermal conductivity rises linearly with temperature. The intensity of this increase and the value of coefficient kef depend on the transverse dimension of the components that form the charge. The results may represent the basis for the validation of various models of effective thermal conductivity with respect to the evaluation of thermal properties of the porous charge.

Published: December 2021

Exposure to metals poses potential health risks, including insulin resistance (IR), to those exposed to them in excess. Limited studies have examined such risks in occupational workers, including welders, and these have yielded inconsistent results. Thus, we examined the associations between exposure to welding metals and IR in welders. We recruited 78 welders and 75 administrative staff from a shipyard located in northern Taiwan. Personal exposure to heavy metals, including chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), and cadmium (Cd), was monitored through particulate matter with an aerodynamic diameter of less than 2.5 μm (PM2.5) and urine analysis by inductively coupled plasma mass spectrometry (ICP–MS). After each participant fasted overnight, blood samples were collected and analyzed for IR assessment through updated homeostasis model assessment (HOMA2) modeling. Air sampling in the personal breathing zone was performed during a Monday shift prior to the blood and urine sample collection the following morning. The welders’ median personal Cr, Mn, Fe, Ni, Cu, and Zn airborne PM2.5 levels and urinary Cd levels were significantly higher than those of the administrative staff. After adjustment for covariates, logarithmic PM2.5-Mn, PM2.5-Fe, PM2.5-Cu, and PM2.5-Zn levels were positively correlated with logarithmic fasting plasma glucose (P-FGAC) levels (PM2.5-Mn: β = 0.0105, 95% C.I.: 0.0027–0.0183; PM2.5-Fe: β = 0.0127, 95% C.I.: 0.0027–0.0227; PM2.5-Cu: β = 0.0193, 95% C.I.: 0.0032–0.0355; PM2.5-Zn: β = 0.0132, 95% C.I.: 0.0005–0.0260). Logarithmic urinary Zn was positively correlated with logarithmic serum insulin and HOMA2-IR levels and negatively correlated with logarithmic HOMA2-insulin sensitivity (%S; βinsulin = 0.2171, 95% C.I.: 0.0025–0.4318; βIR = 0.2179, 95% C.I.: 0.0027–0.4330; β%S = −0.2180, 95% C.I.: −0.4334 to −0.0026). We observed that glucose homeostasis was disrupted by Mn, Fe, Cu, and Zn exposure through increasing P-FGAC and IR levels in shipyard welders.

Published: December 2021

Muslims worship together more frequently than members of other religions. They pray in congregation at the mosque five times a day, causing the mosque to become a central hub for COVID-19 transmission. Therefore, the adoption of protective measures as a method of mitigating the COVID-19 pandemic in mosques is vital. This study aims to account for the implementation status of protective measures in mosques in Surakarta City, Indonesia, during the COVID-19 pandemic. A cross-sectional survey was conducted using a structured questionnaire sent to mosque caretakers as research participants. The mosques were chosen using a simple random sampling technique for a total sample of 247 mosques in Surakarta City. Participants were asked how often they implement the following protective measures in mosques, as recommended by the Majelis Ulama Indonesia: checking body temperature before entering the mosque, prayer distancing, carrying own prayer mat, wearing a mask when praying and no handshaking after prayer. The prevalence of the adoption of protective measures was revealed to be amongst 44.6% to 92.6%, with the lowest prevalence in checking body temperature before entering the mosque. Overall, only 33.7% of mosques implemented all protective measures. In mosques affiliated with Nahdlatul Ulama and the small mosques, the prevalence of protective measures was lower than in mosques affiliated with Muhammadiyah and the large mosques, respectively, suggesting that it is crucial to develop targeted health messages for these groups. Finally, as religious communities remain active in congregational worship during the outbreak, the contradictions between medical and religious practices must be addressed in society for believers to adopt public health policies and for policymakers to comprehend the importance of religious observances.
Continuity and Analyticity for the Generalized Benjamin–Ono Equation
Authors: Pan Xiaolin , Wang Bin , Chen Rong
Published: December 2021

This work mainly focuses on the continuity and analyticity for the generalized Benjamin–Ono (g-BO) equation. From the local well-posedness results for g-BO equation, we know that its solutions depend continuously on their initial data. In the present paper, we further show that such dependence is not uniformly continuous in Sobolev spaces Hs(R) with s>3/2. We also provide more information about the stability of the data-solution map, i.e., the solution map for g-BO equation is Hölder continuous in Hr-topology for all 0≤r<s with exponent α depending on s and r. Finally, applying the generalized Ovsyannikov type theorem and the basic properties of Sobolev–Gevrey spaces, we prove the Gevrey regularity and analyticity for the g-BO equation. In addition, by the symmetry of the spatial variable, we obtain a lower bound of the lifespan and the continuity of the data-to-solution map.

Chlorine is a widely used disinfectant and oxidant used for an array of municipal and industrial applications, including potable water, swimming pools, and cleaning of membranes. The most popular method to verify the concentration of free chlorine is the colorimetric method based on DPD (N, N-diethyl-p-phenylenediamine), which is fast and reasonably cheap, but DPD and its product are potentially toxic. Therefore, a novel, environmentally friendly colorimetric method for the quantification of residual chlorine based on the food additive pyridoxamine (4-(aminomethyl)-5-(hydroxymethyl)-2-methylpyridin-3-ol) was investigated. Pyridoxamine is a B6 vitamin with an absorption maximum at 324 nm and fluorescence emission at 396 nm. Pyridoxamine reacts rapidly and selectively with free chlorine, resulting in a linear decrease both in absorbance and in emission, giving therefore calibration curves with a negative slope. The pyridoxamine method was successfully applied for the quantification of free chlorine from 0.2 to 250 mg/L. Using 1 cm cuvettes, the limit of quantification was 0.12 mg Cl2/L. The pyridoxamine and the DPD methods were applied to actual environmental samples, and the deviation between results was between 4% and 9%. While pyridoxamine does not react with chloramine, quantification of monochloramine was possible when iodide was added, but the reaction is unfavourably slow.
Investigation of the Combined Effects of Rising Temperature and Pesticide Contamination on the Swimming Behaviour of Alpine Chironomids
Authors: Lencioni Valeria , Di Nica Valeria , Villa Sara
Published: December 2021

Some pollutants can be transported through the atmosphere and travel medium–long distances to be deposited in glaciers at high altitude and latitude. The increase in the rate of glacier melting due to global warming can release these pollutants in alpine streams. This study investigated the combined effects of rising temperatures and chlorpyrifos (CPF) contamination on the swimming behaviour of alpine chironomids collected in a shrinking alpine glacier. We assessed the individual and interaction effects of rising temperatures (2–11 °C) and CPF concentrations (0–110 ng L−1) on the swimming behaviour of Diamesa zernyi (Chironomidae) larvae. Distance (mm) and speed (mm s−1) were recorded using a video-tracking system after 24–72 h of treatment. The two stressors caused different effects on distance and speed, with increasing temperature generally causing hyperactivity and CPF from hyperactivity to reduced mobility. Two interactions were detected between stressors when combined: (i) CPF superimposed the effect of temperature on both behavioural endpoints i.e., with 110 ng L−1 of CPF, at 11 °C, larvae moved less; (ii) warming (11 °C) magnified the negative effect of CPF: the smallest distance and slowest speed were recorded at the highest values of the two stressors after 72 h. Our results suggest that water contamination by CPF, even at sub-lethal concentrations, might increase the sensitivity of chironomids to warming, and vice versa, raising concerns about freshwater biodiversity conservation under climate change.
Study on Parameters of Two Widely Used Cohesive Soils Erosion Models
Authors: Wang Qiusheng , Zhou Pengzhan , Fan Junjie , Qiu Songnan
Published: December 2021

The erosion rate of cohesive soils was typically modeled with the excess shear stress model and the Wilson model. Several kinds of research have been conducted to determine the erodibility parameters of the two models, but few attempts have been made hitherto to investigate the general trends and range of the erodibility parameter values obtained by the commonly used Erosion Function apparatus. This paper collected a database of 177 erosion function apparatus tests to indicate the variability of all erodibility parameters; the range of erodibility parameters is determined by data statistics and parameter theoretical value derivation. The critical shear stress (τc) and erodibility coefficient (Z0) in the over-shear stress model have a positive proportional relationship when the data samples are sufficient. However, there is no such relationship between the erodibility coefficient (b0) and erodibility coefficient (b1) in the Wilson model. It is necessary to express the soil erosion resistance by considering all erosion parameters in the erosion model. Equations relating erodibility parameters to water content, plasticity index, and median particle size were developed by regression analysis.

Published: December 2021

The knowledge of climate change effects on variations of winter wheat yields are crucial for productions. Our objectives were to investigate the relationship between yield-related indices of winter wheat and the related climatic variables (selected using variance inflation factors) at the 20 sites of Xinjiang, China over 1981–2017. The background of climate and yield changes was analyzed from temporal and spatial respects. The number of independent climatic variables was selected with the variance inflation factor method to remove the multicollinear feature. The Pearson correlation was conducted between the first difference values of climatic variables and yield-related indices of winter wheat (namely plant height, growth period duration, 1000-kernel weight, kernel number per ear, biomass and yield) to find the key climatic variables that impacted winter wheat growth and yields. The multi-variate linear and nonlinear functions were established step by step using the selected key climatic variables. The best function was determined for each site (significant for p < 0.05). From the results, there were general wetter and warmer trends of the climatic variables. Correspondingly, shortened winter wheat phenology and increased growth and yields were observed for most sites. Still, the climatic trends had mixed effects on winter wheat yields. The effects of precipitation, mean air temperature and relative humidity on plant height and growth period duration agreed well. Different sites had different major climatic drivers for winter wheat growth or yields, and the best functions of growth and yields could be linearly or nonlinearly, mostly described by multi-variate functions. The winter wheat growth or yield indices were also found to be closely connected with the soil water content status at the eight sites. The relationship between winter wheat growth or yield and climate provided useful references for forecasting crop production and for projecting the impact of future climate changes.
Water Management Balance as a Tool for Analysis of a River Basin with Conflicting Environmental and Navigational Water Demands: An Example of the Warta Mouth National Park, Poland
Authors: Pusłowska-Tyszewska Dorota
Published: December 2021

Allocating finite water resources between different water uses is always a challenging task. Searching for a solution which satisfies the water needs (requirements) of all water users without compromising the water requirements of river ecosystems calls for analyzing different water management options and their expected consequences. Water management balances are usually used for comparison of water resources with the needs of water users. When aquatic and water dependent ecosystems are considered in a similar manner as other users, searching for the optimum water resources allocation, without neglecting requirements of the natural environment, is possible. This paper describes basic modeling assumptions and methodological solutions, which allow for taking into account some tasks related to the protection of aquatic and water dependent ecosystems. The water balance model, developed for a catchment comprising the Warta Mouth National Park, was applied to find out whether supplying adequate amounts of water for conservation (or restoration) of wet meadows and wetland habitats in the area is possible, while still satisfying the demands of other water users.
Ciudades emblemáticas del pasado: de la ciudad primigenia (Uruk-Warka) a la megalópolis arquetípica (Teotihuacan)
Authors: Manzanilla Linda R.
Published: December 2021

Este trabajo aborda un tipo particular de asentamiento urbano que fue excepcional en su área, y constituyó un arquetipo en el centro de México; se trata de un asentamiento que experimentó procesos precoces de cambio en lo que V. Gordon Childe denominó “la revolución urbana”. Cuando se compara Teotihuacan (durante el periodo Clásico de Mesoamérica, 100-650 d.C.) con los primeros asentamientos urbanos de la Baja Mesopotamia durante el periodo Uruk tardío (3500-3100 a.C.), como Uruk-Warka, las respectivas transformaciones cualitativas que implicaron estos procesos crearon formas innovadoras de vida civilizada, un nuevo tipo de sitio en cada región, y novedosas formas de interacciones sociales y especializaciones en la población urbana. Sin embargo, existen diferencias entre estas dos regiones que deben ser enumeradas. La jerarquía desarrollada de asentamientos con cuatro niveles que es característica de la Baja Mesopotamia no está presente en la cuenca de México durante el periodo Clásico; la retícula urbana ortogonal y la sociedad multiétnica de Teotihuacan son nuevos fenómenos no compartidos por las ciudades tempranas de la Baja Mesopotamia, aun cuando probablemente se presentaron en el valle del río Indo algunos siglos después.
La expansión Uruk y el proceso de urbanización: una perspectiva desde la Alta Mesopotamia
Authors: Constanze Lima Leandro
Published: December 2021

En la región de la Alta Mesopotamia, durante el período que abarca el Calcolítico Tardío 4 y 5 (3600-3000 a.C.) se observa la aparición de diversos asentamientos con características urbanas. El surgimiento de estos sitios y el material arqueológico hallado en los mismos planteó diversas cuestiones respecto a su origen. En este artículo proponemos un relevamiento del acervo teórico, haciendo foco en los modelos que relacionan a estos centros urbanos con una dinámica de centro-periferia y el análisis desde la perspectiva de las redes de intercambio regionales, sin dejar de lado el desarrollo propio interno de cada asentamiento. Consideramos particularmente tres sitios específicos que presentan vertientes distintas de formación urbana donde la intensidad de la injerencia externa también es variable. En el yacimiento de Habuba Kabira observamos una fuerte presencia de población Uruk, lo que podría responder al asentamiento de una diáspora dominante proveniente de la Baja Mesopotamia. Mientras que en el sitio de Hacinebi Tepe parecen convivir una comunidad local y una comunidad foránea autónoma inserta en ella. Finalmente, en Tell Brak se manifiesta un centro autóctono independiente que, según nuestro parecer, se habría apropiado de ciertos rasgos culturales Uruk.
La destrucción de Jericó a fines de la Edad del Bronce Antiguo III: un análisis preliminar de diferentes interpretaciones
Authors: Kifer Katherine
Published: December 2021

El objetivo del presente artículo es analizar las perspectivas sobre las transformaciones ocurridas en Jericó a fines de la Edad del Bronce Antiguo III (ca. 2700/2650-2300 a.C.). Para esto se comparan brevemente los restos materiales correspondientes al Bronce Antiguo III y el período siguiente, el Bronce Antiguo IV (ca. 2300-1950 a.C.). Tras ello, se pretende debatir sobre si estos cambios deben interpretarse como un “colapso” del sistema o una “adaptación paulatina” a las nuevas condiciones y demandas regionales. Al respecto, cabe señalar que mientras muchos sitios eran abandonados, Jericó experimentó un tiempo de florecimiento económico y desarrollo urbano sin precedentes, pero que en torno al 2350 a.C. se vio interrumpido de manera abrupta: al parecer, ingresaron enemigos a la ciudad, saqueando todo lo que allí había, incluidas las riquezas del palacio y el templo. En simultáneo, es probable que incendiaran las murallas de la ciudad. Años después, el asentamiento sería rehabitado por grupos de pastores-guerreros procedentes, aparentemente, de la Alta Mesopotamia, quizás motivados a trasladarse por causa de las alteraciones medioambientales en sus tierras de origen.

Published: December 2021

Using the regression model, a method that accommodates variables related to each other is called the simultaneous equation method. The study aims to determine the factors affecting inflation and rupiah exchange rate and model simultaneous equations towards the factors affecting inflation and rupiah exchange rate in Indonesia using Two-Stage Least Square. Data used in this study are secondary data obtained from the website of Statistics of Indonesia. Findings on the simultaneous equation model with two-stage least squares reveal that variables that significantly affect inflation are the Indonesia rupiah exchange rate and money supply. At the same time, variables that significantly affect the Indonesian rupiah exchange rate are inflation and money supply. The predictive value using the inflation and rupiah exchange rate equation indicates that the obtained MAPE (Mean Absolute Percentage Error) value does not exceed 50%. In conclusion, the prediction result using the inflation and Indonesia rupiah exchange rate equation is accurate.

Крім того, вона зацікавилася народним мистецтвом, а ще міфологією і фольклором, побутом і обрядами Волині й Полісся як регіонів України, ставши їх гарним знавцем. Про це свідчить, наприклад, здійснений нею в художньому творі точний опис рідкісного природного явища, яке на Волині і Поліссі називається Перелесником. Крім того, в статті стверджується про вплив ідей гілозоїзму на світогляд, мислення та естетичні спонуки творчості письменниці, як засвідчує авторський текст і фабула її драми-феєрії "Лісова пісня". При аналізі такого явища, як "естетика чудесного", в даному дослідженні також розглянуто зв'язок естетичного і міфологічного компонентів цього художнього твору.
ФІЛОСОФСЬКИЙ ДИСКУРС СВІТУ ТВАРИНИ М. ХАЙДЕГГЕРА
Authors: Чаплінська О.
Published: December 2021

У статті здійснено філософську рефлексію світу тварини у курсі лекцій 1929–1930 рр. М. Хайдеггера. Визначено, що його феноменологічно-екзистенціалістський аналіз тварини розкриває її навколишнє середовище через тезис ''тварина бідна у світі (weltam)'', що реалізується у негативний спосіб через позбавлення, а властивий їй спосіб буття розуміється як заціпеніння (Benommenheit) і є умовою поведінки. Онтологічний статус тварини усвідомлюється ним як відкритість без розкриття.
Образи соціального зла у творах Альбера Камю
Authors: Савонова Г.
Published: December 2021

У статі обґрунтовується проблема соціального зла в творчості А. Камю, робиться акцент на антихристиянському компоненті розуміння зла філософом у творах ''Сторонній'', ''Калігула'', ''Праведники''. З’ясовується, що дихотомія зла прямо пропорціональна абсурдності людського існування, залежить від кількості та якості соціального добра, його розуміння людством. Досліджується проблема життя та смерті, як дилема етичної дії особистості, робиться акцент на філософії зла, що витікає з проблеми абсурдності людського існування в межах питання: ''жити, чи померти''.

La presente tesis hace inicialmente un acercamiento teórico a la comunicación desde una perspectiva decolonial, como propuesta que se opone a la modernidad/colonialidad, para lo cual fue necesario recorrer los postulados de estos estudios planteados desde la filosofía y la sociología y aterrizarlos en la comunicación. Este acercamiento permitió definir las categorías que sirvieron de análisis para las prácticas comunicativas de los pueblos originarios suramericanos tomados como muestra: colonialidad y decolonialidad del poder, colonialidad y decolonialidad del saber, colonialidad y decolonialiad del ser, colonialidad y decolonialidad del lenguaje y colonialidad y decolonialidad de la naturaleza. En una segunda parte se hace un acercamiento general a las prácticas comunicativas ancestrales de los pueblos originarios: Mapuche, Mbyá guaraní, Aymara, Panzaleo y Nasa, para luego adentrarse en la particularidad de cinco medios de comunicación representativos de cada una de estas comunidades: Canal Wall Kintun de la comunidad Mapuche Buenuleo ubicada en San Carlos de Bariloche, provincia de Río Negro, Argentina; Emisora Che Iro Arapoty de la parcialidad Mbya Apytere, localidad Juan Eulogio Estigarribia (conocida como Campo 9), departamento de Caaguazú, en la república de Paraguay; Proyecto plurinacional de la Coordinadora Audiovisual Indígena de Bolivia CAIB, que abarca comunicadores de las diferentes nacionalidades, especialmente Aymaras, Quechuas y guaraní bolivianos; Canal TV MICC del pueblo Kichwa Panzaleo, ubicado en Latacunga, provincia de Cotopaxi, Ecuador y Tejido de comunicaciones Wejia Ka’asenxi, del Cabildo Nasa, ubicado en Corinto, Cauca, Colombia. Cada una de estas prácticas comunicativas mediáticas originarias son analizadas desde las categorías coloniales y decoloniales del poder, saber, ser, lenguaje y naturaleza. Una tercera parte de la tesis analiza de manera general el comportamiento en conjunto de las cinco prácticas trabajadas, lo que desde los pueblos originarios se denomina como el ‘caminar de la palabra’, en relación con las categorías coloniales y decoloniales planteadas. Finalmente se hace una prospectiva de la comunicación originaria suramericana y mediante herramienta diagnóstica se plantean resultados y conclusiones que muestran unas prácticas con mayor manifestación decolonial.

Оценка интенсивности ощутимых землетрясений, зарегистрированных КФ ФИЦ ЕГС РАН до
1 сентября 2017 г., осуществлялась специалистами по шкале сейсмической интенсивности MSK64 [1]. С 1 сентября 2017 г. для оценки макросейсмической интенсивности введен впервые
национальный стандарт РФ ГОСТ Р 57546–2017 – шкала сейсмической интенсивности ШСИ-17 [4].
Затем с 1 сентября 2019 г. в качестве национального стандарта РФ введен принятый 20 декабря
2018 г. межгосударственный стандарт ГОСТ 34511–2018 – макросейсмическая шкала интенсивности
землетрясений МШИЗ-18 [2]. Обе шкалы в настоящее время являются действующими.
Установленный в них порядок получения оценки интенсивности ощутимого землетрясения в баллах
позволяет использовать шкалы в автоматической обработке макросейсмической информации,
полученной через online-анкету КФ ФИЦ ЕГС РАН (http://www.emsd.ru/lsopool/poll.php) [3]. В работе
представлено сравнение результатов автоматических оценок интенсивностей двух алгоритмов,
используемых в шкалах ШСИ-17 и МШИЗ-18, по данным ощутимых землетрясений до 5 баллов.

Существующие в настоящий момент методы определения периодов повышения сейсмической
активности на Камчатке [7] на основе анализа только ионосферных прогностических признаков не
дают ответа на вопросы ни о силе события, ни о месте его возникновения. Возникает необходимость
объединения методов мониторинга сейсмического режима на основе анализа каталога землетрясений
(среднесрочный прогноз) и геофизического мониторинга на основе изучения ионосферных
параметров (краткосрочный прогноз) с целью разработки методов предупреждения о грозящей
опасности, определяя возможную область и период ожидания землетрясения. В данной работе
произведены прогностических оценок вероятности, возможной области ожидания и временного
периода наступления сильных землетрясений с энергетическим классом KS≥13.5 (M≥6.0) в
Камчатском регионе за 01.01.2019‒01.06.2021 гг. на основе совместного анализа аномальных
значений сейсмического прогностического признака, полученного на основе вероятностной модели
сейсмического режима, и комплекса ионосферных предвестников.
СЕЙСМИЧЕСКАЯ АКТИВНОСТЬ ТЕРРИТОРИИ ПРИМОРСКОГО КРАЯ И ЯПОНСКОГО МОРЯ ЗА ПЕРИОД 2019-2020 ГОДЫ
Authors: Лисунов Е.В.
Published: December 2021

Территория приморского края и прилегающей акватории Японского моря являются
относительно спокойным сейсмоактивности регионом с точки зрения сильных сейсмических
событий. Ежегодно, за время работы Регионального Информационно-обрабатывающего Центра
«Владивосток» (РИОЦ), здесь регистрируется в среднем от 15 до 30 сейсмических событий [2, 4]. Как
правило, большая часть очагов землетрясений расположена на больших глубинах (100-600 км).
Оставшиеся мелкофокусные землетрясения являются достаточно слабыми, с магнитудами 1-3.
Однако иногда происходят сейсмические события, которые ощущаются местными жителями и
вызывают небольшие колебания зданий. Известно о большом количестве проявлений сейсмической
активности в Лазовском, Хасанском, Тернейском и в Пожарском районах, а также во Владивостоке,
Артёмовском городском округе и в близи озера Ханки [1, 3]. Помимо территории Приморского края,
наблюдение за акваторией Японского моря представляет не меньшую важность. История
наблюдений показывает, что достаточно сильные землетрясения в Японском море способны вызвать
цунами с высотой волны до 4-5 метров на восточном побережье края. Последнее ощутимое ценами
произошло в 1993 году в результате землетрясения магнитудой 7.7 в районе острова Хоккайдо,
Япония. Все эти случаи подтверждают важность и необходимость непрерывного сейсмического
мониторинга в регионе. В сети РИОЦ «Владивосток» находится 4 сейсмостанции: VLAR-RU
(Владивосток), MSH (м. Шульца), PSTR-RU (Посьет), PLTR-RU (Полтавка). Основная деятельность
СП СПЦ РИОЦ «Владивосток» - круглосуточный мониторинг землетрясений Приморского края, и
ближайших приграничных территорий, а также Японского моря, в зоне ответственности – 1000 км от
г. Владивосток.
НОВОЕ О ПРИРОДЕ ГЛУБОКОФОКУСНЫХ ЗЕМЛЕТРЯСЕНИЙ
Authors: Родкин М.В.
Published: December 2021

Давно известен парадокс сейсмичности [2, 3, 6, 8, 9, 12 ]. Легко показать, что в условиях температур и давления недр Земли хрупкое разрушение по модели Рида невозможно на глубинах более 30-50 км. В то же время, землетрясения более-менее непрерывно продолжаются до глубин более 700 км, причем никаких изменений в параметрах очагов землетрясений от глубины, несмотря на значительные усилия, выявлено не было. Выявляются только некоторые второстепенные различия; у глубоких землетрясений в среднем меньше афтершоков, и характер излучения глубоких очагов имеет более симметричные нарастание и спад [12, и др.]. Для объяснения глубоких землетрясений были предложены модели, предполагающие решающую роль процессов дегидратации и фазовых переходов. Модель дегидратации является самой распространенной для объяснения промежуточных землетрясений, с глубинами от 70 до 300 км [3, 10-12, и др.]. Предполагается, что высокое давление выделяющегося флюида компенсирует рост давления с глубиной и позволяет реализоваться обычным сдвиговым подвижкам. Отметим, что предположение о таком механизме предполагает возможность реализации такого же механизма и в вышележащих слоях, куда флюид внедряется под высоким давлением. Меньше единодушия в вопросе о природе глубоких землетрясений, с глубиной очага более 200-300 км. Обычно предполагалась связь с фазовыми превращениями в верхней мантии, тем более что в распределении числа землетрясений с глубиной (рис. 1) намечаются максимумы сейсмичности на глубинах фазовых превращений [3, 4, 7, 8, 10, и др.]. Графики, аналогичные представленному на рис. 1, традиционно используются в качестве свидетельства связи глубоких землетрясений с превращениями вещества погружающихся литосферных плит.
