Legal issues and prospects for delimitation of continental shelf in the Arctic
Authors: Moroz Elena Nikolaevna
Published: September 2021

This article is dedicated to the relevant problem of delimitation of the Arctic territories. There are currently several different approaches towards this question, but the effective one is the mechanism proposed by the United Nations Convention on the Law of the Sea. The absence of consensus on delimitation of continental shelf is substantiated by the intersection of interests of the countries in the Arctic region and strategically crucial consequences of dividing the Arctic: this is the matter of national security, geopolitical supremacy, increase of economic potential, energy and environmental security. The goal of this research consists in the analysis of recent achievements and prospects for delimitation of continental shelf. The subject of this article is the problems of delimitation of the jurisdiction of countries in the Arctic region. Methodological framework is comprised of the chronological method and method of analysis. The conclusion is made that the definition of state boundaries in the Arctic is a long process; since the decisions of the Commission on the Limits of the Continental Shelf is of advisory nature, it may lead to the disputes between the countries over the rendered decisions. It should be noted that international law has the essential mechanisms and means for the peaceful delimitation of maritime boundaries in Arctic waters. The author believes that the final definition of boundaries in the Arctic would be achieved through the compromise between the polar countries, and thus signing bilateral agreements without relying on recommendations of the Commission. It is underlined that the conventional principle of delimitation of boundaries in the Arctic Ocean does not meet the national interests of the Arctic Five, and requires a different approach due to the peculiarities of the ocean. The scientific novelty lies in the analysis of existing principles, instruments and problems of delimitation of boundaries in the Arctic, as well as in conclusions formulated by the author. The solution to the outlined problems can become the preservation of the international seabed within the framework of the concept common heritage of mankind in the area of the Gakkel Ridge, and in the area of Lomonosov Ridge delineation by the sectoral principle.

Authors: Stearns Zachary R. , Carvalho Marissa L. , Beneciuk Jason M. , Lentz Trevor A.
Published: September 2021

Background

Psychological factors influence or are associated with physical function, pain, and health care costs among individuals with musculoskeletal pain conditions. Recent clinical practice guidelines recommend screening for psychological factors (also referred to as “yellow flags”) in physical therapy practice to help understand prognosis and inform shared decision making for treatment.

Clinical Question

Despite the urgings of clinical practice guidelines and evidence of the influence of psychological factors on clinical outcomes, screening for yellow flags is uncommon in clinical practice. Clinicians may feel uncertain about how to integrate screening tools into clinical practice, and how screening results might inform decision making and care coordination.

Key Results

We outline a 3-step framework for routine yellow flag screening in physical therapy practice: (1) establish a standard first-line screening instrument and process, (2) interpret the results to inform shared decision making, and (3) monitor treatment progress. Four case examples illustrate how yellow flag screening can help clinicians and patients decide whether the patient might benefit most from standard physical therapy, psychologically informed physical therapy, psychologically informed physical therapy with referral to another health care provider, or immediate referral.

Clinical Application

Consider incorporating a standard yellow flag screening process into usual musculoskeletal health care. We present a framework to guide yellow flag screening in practice (1) to help inform treatment pathway selection and (2) to enhance interdisciplinary communication.

Published: September 2021

The emergence of videos as instructional media in the EFL learning contexts has provided meaningful values to learners’ learning experiences. There have been many studies investigated the effectiveness of the videos in EFL field. However, this study presents a gap in the literature regarding the acceptance of videos usages of Indonesian senior high school students who learn English as a foreign language. This study employed quantitative survey research by distributing a closed questionnaire to one hundred fifteen students from the tenth grade of a state senior high school. Overall, participants showed positive voices towards using videos to support their learning in terms of ease of use, learning opportunities, learning experience, and preferences. With regard to the actual use of videos in learning, most students spent at least 1-2 hours watching videos in and outside the classrooms. The availability of smartphones contributes significantly to ease video access. Moreover, social media networking, such as Youtube, Instagram, and WhatsApp, provides more video sources for the student. Amongst the video types enjoyed by the students, videos of interviews, tutorials, explanations, vlogs, profiles, and testimonials were their preferences.

Published: September 2021

Nutrition is a very important part of growth and development. Community problems are considered serious if the prevalence of underweight is between 10.0-14.0%, and is considered critical if it is greater than 15.0% (WHO, 2010). In 2013, nationally the prevalence of underweight in children under five was still 12.1%. For Jambi Province itself, cases of malnutrition tended to increase over the last two years, in 2017 there were 85 cases of malnutrition and four cases died, while in 2018 it rose to 92 cases with six of them died. This study is an analytical study with a cross-sectional design that aims to determine the relationship between diet and mother's knowledge with the nutritional status of children under five in Talang Babat Village, Tanjung Jabung Timur Regency in 2019. This research was conducted in July 2019. The population in this study was 220 toddlers. The number of samples was calculated based on Ariawan's formula as many as 67 people. The sampling technique was carried out by means of quota sampling. Data analysis used the chi-square test with a significant limit of = 5%. The results of the study Most of the respondents had normal nutritional status as many as 50 respondents (74.6%), had a good diet for toddlers as many as 37 respondents (55.2%) and had less knowledge about the nutritional status of toddlers as many as 43 respondents (64.2%). Based on the chi-square statistical test with p-values ​​of 0.028 and 0.001 which means there is a significant relationship between diet and knowledge with the nutritional status of children under five in Talang Babat Village, Tanjung Jabung Timur Regency. From the results of the study, it can be concluded that there is a significant relationship between diet and knowledge with the nutritional status of toddlers in Talang Babat Village, Tanjung Jabung Timur Regency.

The aim of this study was to estimate the prevalence of animal trypanosomosis and its impact on the Packed red Cell Volume (PCV) in Vogan sheep (VS) and Djallonke sheep (DS) in two administrative regions of southern-Togo (Maritime and Plateau Regions). A total of 206 samples (104 VS and 102 DS) were analysed by microscopic observation of buffy coat, PCR and indirect ELISA. Using the three diagnostic techniques, the prevalence was 24.51% in Djallonke sheep and 20.19% in Vogan sheep with a clear predominance of Trypanosoma vivax infection. Geographical location (canton) influenced significantly the prevalence of trypanosome infections and the PCV; the highest recorded prevalence was obtained in Dagbatchi and Sevagan locations, associated with the lowest PCV. No significant difference was observed between PCV of VS and those of DS in Maritime Region. We concluded that even with a phenotype of Sahelian sheep, VS is well adapted in this area and has developed a certain degree of trypanotolerance similar to DS. However, Djallonke sheep in the Maritime Region (Vo Prefecture) might have become less trypanotolerant comparatively to those originating from the Plateau Region. These results could be used to update the epidemiological situation of trypanosomosis in this region and showed that the sheep genetic improvement strategies should take into account animal trypanosomosis.

Ce travail présente les résultats d’une méta-analyse de quatre études menées sur les Amphibiens à Kasugho, Butembo, Mambasa et Kisangani en République Démocratique du Congo. L’objectif principal était de vérifier le lien entre le taux d’anthropisation des habitats et la fréquence des espèces observées afin d’identifier d’éventuelles espèces indicatrices des perturbations anthropiques. L’observation directe a généré 815 Amphibiens capturés dans les habitats anthropisés (étang piscicole, jachère) et non anthropisés (marécage, forêt secondaire, forêt primaire). Sur les 37 espèces identifiées, 2 (Amietophrynus kisoloensis, Hoplobatrachus occipitalis) vivent uniquement dans les habitats anthropisés et 11 (Afrixalus quadrivittatus, Amietophrynus gracilipes, Arthroleptis variabilis, Cardioglossa gracilis, C. leucomystax, Hyperolius viridiflavus, Leptopelis aubryioides, L. ocellatus, Phrynobatrachus auritus, Ptychadena anchietae, P. chrysogaster) préfèrent uniquement les habitats non anthropisés. La plus forte similarité entre les habitats anthropisés et non anthropisés a été observée à Mambasa (étang piscicole, marécage, jachère, forêt secondaire, forêt primaire) et la plus faible entre les habitats à Butembo (marécage, jachère). Un test de Chi-carré souligne un lien entre le statut d’habitat et les abondances d’Amphibiens. Une corrélation linéaire significative confirme qu’il n’y a pas de relation directe entre les fréquences dans les deux statuts d’habitat. La présente étude confirme le potentiel des Amphibiens comme indicateurs de perturbations anthropiques des écosystèmes.

L’objectif de cet article est d’identifier, parmi sept nouveaux génotypes (P 625-1, P 746-1, Q 674-2, Q 723-4, Q 792-2, R 663-4 et R 689-1) de cotonnier, ceux dont les performances sont supérieures à celles des trois variétés actuellement vulgarisées au Bénin (ANG956, OKP768, KET782). De 2015 à 2017, 146 essais variétaux ont été conduits en milieux contrôlé et paysan. Tous les nouveaux génotypes sont évalués en milieu contrôlé alors que seuls P 625-1 et P 746-1 sont testés par les paysans. Le dispositif expérimental est un Bloc Aléatoire Complet. Une analyse de variance suivant un modèle linéaire mixte a été conduite. L’interaction génotype x environnement a été estimée par le modèle Additve Main effects and Multiplicative Interaction (AMMI). Les rendements étaient faibles en 2015 et se sont progressivement améliorés, sans interactions génotype x année significative. L’interaction génotype x zone est faible (1,5 %) mais significative (P<0,001). Les génotypes R 663-4 et P 625-1 sont les plus performants en milieu contrôlé respectivement dans les zones nord et sud. En milieu paysan, le génotype P 746-1 est meilleur dans la zone nord. Il en est de même pour le génotypes P 625-1 dans la zone sud.

Published: September 2021

This study reports on the evaluation of 46 Acacia mangium provenances and varieties, which were planted in 2006 on the Ibi-Batéké Plateau, Democratic Republic of the Congo. After seven years, tree height and diameter, biomass and carbon stocks of the 46 Acacia mangium provenances, together with soil carbon and nitrogen concentrations, were compared with savannah soils in which Acacia was no present. Heights and diameters of 20 to 25 trees per provenance were measured. Carbon in the biomass was determined by the direct method. In total, 25 trees were harvested and weighed for each carbon compartment (leaves, branches, litter, trunks and roots). Ninety soil samples were collected at three different depths in the provenance plots and on the savannah and analyzed for their C and N concentrations. There were differences in height and diameter growth and in accumulated carbon among trees of different origins (provenances). Finally, soil C and N differed under different provenances, and with depth. Carbon and nitrogen tended to decrease with depth. The results of the study revealed better performance for provenances originating from Papua New Guinea, Australia, Malaysia, Vietnam, China, Fiji and the Philippines.

Systems of Pain/Networks of Resilience (Nebraska) is a performance for camera. Chapters of the work have developed in Omaha, Nebraska, upstate New York, Galesburg, Illinois and Santa Fe, New Mexico. (Nebraska) is the first chapter, originally performed live at the Bemis Center for Contemporary Arts. Within the project, pain is understood as trauma, loss, disruption—everything from polluted landscapes to neglect, from abusive relationships to work stress. Resilience is similarly embraced in an expansive, cross-disciplinary way, invoking everything from the ability of an ecosystem to adapt to disruption, to a human’s ability to cope with traumatic events.

Published: September 2021

One of the psychological problems experienced by stroke patients is self-efficacy. Stroke patients on average lack confidence in themselves to do exercises or activities that will have an impact on the recovery process of stroke patients. Several factors that vary related to low self-efficacy in stroke patients are one of the causes. The scoping review aims to identify factors related to self-efficacy in a post-stroke patient. The methods use a systematic review through review articles relevant to the topic from CINAHL database, MEDLINE, Academic search ultimate, science direct, and Taylor & Francis with a publication year spanning 2015 to 2020 and with the keyword “self-efficacy” and “stroke” then analyzed using a synthesis matrix. The inclusion criteria in this study were articles in English with longitudinal study design or cross-sectional study and self-efficacy as the dependent variable. The results of a review of four journals that met the inclusion criteria found factors related to self-efficacy in a post-stroke patient including depression, age, vascular history, fear, physical activity, Body Mass Index (BMI) and emotional function. The study concludes that depression, age, vascular history, fear, physical activity, Body Mass Index (BMI) and emotional function are factors related to self-efficacy in post-stroke patients. The factor most strongly associated with post-stroke patients self-efficacy is depression.

Published: September 2021

In 1992, a pilot project for collecting information on the socioeconomic and nutritional status of children and their mothers as part of the early warning system was implemented in two villages in Kassala Province, Sudan. The objectives were to test the feasibility of local participation in socioeconomic and nutritional data collection, analysis and utilization;and to incorporate socioeconomic data into the food and nutrition information system, and examine its usefulness in early warning. The pilot project also included the introduction of new parameters such as adult anthropometry, i. e. body mass index of the mothers of the children seen, to monitor the nutritional status of both children and their mothers at the same time. This led to very interesting results which played a major role in determining the type of intervention needed

Published: September 2021

To determine the importance of sinusitis as a cause of orbital cellulitis, the causative organisms and peak age of occurrence, 25 patients hospitalized with orbital cellulitis (ages 8 months to 17 years; 80%, 1-4 years) were studied. Complete blood counts were carried out and radiographic sinus examinations and eye swabs (for culturing) performed prior to antibiotic treatment. Sinusitis was evident in 72% of the patients. Eye swab cultures indicated 80% had streptococcal, staphylococcal or enterococcal infection. The data indicate that sinusitis is an important cause of orbital cellulitis. The most common causative organisms were Streptococcus viridans (44%) and Staphylococcus aureus (32%). Initial antibiotics should therefore cover both organisms.

Published: September 2021

A species-specific polymerase chain reaction [PCR] assay was used to identify the species composition of the Anopheles fluviatilis complex in the Islamic Republic of Iran. All the amplified DNA samples from specimens collected from different areas yielded a fragment of 450 bp size, a PCR product corresponding to that of the species denoted as Y. The sequence data from 21 ITS2 [second internal transcribed spacer] regions were compared with those publicly available in the GenBank database and confirmed that the specimens were 100% identical to species Y of India. Species Y is presumably the same as species T that has no role in transmission of malaria in India, whereas An. fluviatilis is known as a secondary vector of malaria in the Islamic Republic of Iran

However, the business undertaken is a monopoly that makes it village unit cooperatives difficult to compete with other parties.
Variación en la intensidad de la isla de calor urbana por efecto del cambio climático en ciudades chilenas
Authors: Henríquez Ruiz Cristian , Smith Pamela , Contreras Paulina , Qüense Jorge
Published: September 2021

La Isla de Calor Urbano (ICU) es la principal característica del clima urbano y se define como la diferencia entre la temperatura urbana y la temperatura rural. Su existencia se explica por el diseño y materiales de construcción de la ciudad, superficies impermeables y no evapotranspirantes, y sus efectos son de diversa índole. La magnitud e intensidad de la ICU depende, a su vez, del tamaño de la ciudad y por ello, del volumen de población concentrada espacialmente. El objetivo de esta investigación es proponer una metodología que permita estimar la intensidad máxima de la ICU presente y futura mediante una aproximación de múltiples modelos (climáticos y de usos de suelo) y considerando los efectos del cambio climático. Los resultados demuestran que la ICU promedio de las principales ciudades chilenas analizadas es consistente con valores de estudios internacionales, destacando el caso del Gran Santiago que llegaría a tener una ICU mayor 10 ºC.
El riesgo de contaminación por ozono en dos ciudades españolas (Madrid y Sevilla). Un estudio realizado con técnicas de modelado espacial y SIG
Authors: Cañada Torrecilla María Rosa
Published: September 2021

El ozono troposférico es uno de los contaminantes que más incide en la salud de las personas y alcanza valores elevados en muchas ciudades españolas durante períodos de alta insolación y elevadas temperaturas. De ahí el interés de analizar su distribución espacial en dos ciudades españolas, Madrid y Sevilla. Dada la escasez de información disponible se ha planteado un doble enfoque. Por un lado, analizar los datos registrados por las estaciones de medición y por otro, los datos estimados mediante interpolación espacial, para conocer la contaminación en todo el espacio urbano. La técnica empleada ha sido la media ponderada por el inverso de la distancia (IDW) por lograr los mejores resultados en cuanto a grado de confianza y criterios estadísticos y geográficos. Los resultados alcanzados muestran que las zonas suburbanas o rurales son las más contaminadas por ozono, constituyendo espacios de riesgo para la población, mientras que en el centro de las ciudades los valores de ozono son mucho más bajos.

Theory of turbulence is an important part of the open flow dynamics. The interes in the research of experimental turbulence increased with the development of mathematical modeling of open flows and the need to obtain materials for the parameters of turbulence models, with numerical modeling of turbulent flows. The purpose of this research was to study characteristics of the turbulent flow during the planned expansion with the formation of whirlpool zones and to obtain practical recommendations for the analysis and calculation of the kinematic structure of such flows. There was used an experimental research method. Experimental graphs for determining the turbulent shear stresses at the interface were obtained and dependences were given for determining the coefficients of turbulent mixing. There were identified zones of intense pulsation of speed which is of a practical interest and allows to predict an increase in the erosion ability of the flow in these places and to obtain recommendations for strengthening the channel and extinguishing energy in the downstream. The results allow us to use this data in further study of the conditions of origination, development and decaying of turbulence, to consider the mechanism of turbulence of energy transformation.

A critical assessment of the methodological decisions taken by the scientific community in the development of thematic maps-schemes of forest zoning is given. It is indicated that in most cases the authors operate with landscape, climatic and geobotanical characteristics of territories, do not rely on the concepts of taxa as elementary territorial units united in homogeneous groups. Most of the zoning schemes recommended for practical use are based on the intuitive and subjective judgments of the authors and, often, do not have a criterion-proven statistical reliability. Most of the zoning schemes recommended for practical use are based on the intuitive and subjective judgments of the authors and, often, do not have a criterion-proven statistical reliability. The article, using the example of the Nizhny Novgorod region, presents a methodology for developing models of multidimensional zoning of forests growing in 40 forest areas (taxa), endowed with 35 indicators characterizing the geographical coordinates of forest centers, soil productivity in 6 classes, climate in 7 indicators, the structure of forest lands in 17 categories, productivity and closeness of plantings under 3 types of forests. In the multidimensional classification (grouping) of forest areas, the methods of factor, cluster and discriminant analysis were used. As a result of analytical calculations, 7 typical forest areas were identified on the territory of the subject of the Russian Federation. The reliability of the classification of forest areas and the resulting zoning map-scheme is confirmed by the statistical criteria of the total intercluster and intracluster distance of Mahalanobis, the Wilkes lambda and Pearson’s Chi-square criteria.

Purpose: increasing the resource potential of objects of reclamation systems by developing a digitalization mechanism and an expert system for managing the efficiency of operation. An algorithm for the formation of the digital identity of individual reclamation systems is proposed, which presents the process of solving the logical problem of assessing the residual resource of individual objects of the reclamation system. The characteristics of the parameters of reclamation objects included in the Database of the expert system, focused on the creation of a flexible platform in the cloud environment with the prospect of predictive forecasting of the functioning efficiency, is given. The expediency of including the digital identity module in the passport of the melioration system has been substantiated. The factors influencing the efficient operation of the objects of reclamation systems are considered. The ranking of normative documents by the classification level of responsible persons has been completed. Requirements have been established for the level of competence of performers in the end-to-end document flow of monitoring the state of objects of reclamation systems throughout the entire period of operation. The fulfilled analysis of the structural elements of the objects of reclamation systems shows that the system of scheduled maintenance and repairs on demand, although it is sufficient to maintain the operable state of reclamation systems as a whole, does not include measures aimed at maintaining the modern level of workability of obsolete facilities. Particular attention in the research is paid to the issue of reducing the cost of operating reclamation facilities by carrying out a phased modernization of not only mechanical systems, but also by including additional modules of digital systems in the design that provide monitoring of the state and control of the complex in real time. The concept of formation of digital identity of objects of reclamation systems is proposed as a mechanism for increasing control over management and resource provision.

The features of the survey, design and operation of irrigation and drainage systems in the area of the international airport «Zhukovsky» located in the Moscow region, Russia. Design surveys included an ornithological survey of the reclaimed area. Bird species, nesting sites and the number of nests were identified. The number of nests before reclamation averaged 200 ± 1.5 (mean ± standard error). Hydro reclamation in the airport area eliminated local swamping areas and nesting areas disappeared. Draining was carried out by open drains. The distance between the open drains is 120 m, the length is from 700 to 1200 m. There are no capital irrigation and drainage facilities. On the polder site the project provides for open drains and drains. The state of the land reclamation system has been deteriorating since 2001. Periodic waterlogging of a part of the polder area and the formation of a nesting area for black-headed gulls are noted. Airbus A321 aircraft fl y over the chicks while feeding at an altitude of 231.5 m, the size of which in the eyes of the chicks is comparable to the size of the parent gulls.

The article discusses an advanced method for cleaning closed horizontal drainage systems in the irrigation zone. The technological process of cleaning from sediment is carried out by dragging winches of a special cable with a ruff, previously laid inside the horizontal closed drainage during primary cleaning with the help of the PDT-200 machine, through adjustable and fixed blocks. While the ruff has the ability to deviate and rotate along the longitudinal axis of the drainage pipe, and the mounting frames are installed in the inspection wells, fixed with bolts and sequentially re-installed from one well to another. The use of this method allows you to reduce the labor intensity, reduce the number of expensive reclamation machines used, special hoses and pumping equipment, as well as the use of manual labor and the consumption of a large amount of water. The improved method will significantly increase the productivity, quality and reliability of the technological process by eliminating the shortcomings in the spring and autumn cleaning of closed horizontal drainage. The effectiveness of the improved method is to increase the productivity and quality of cleaning the closed horizontal drainage from sediments, as well as to a sharp decrease in the level of mineralized groundwater.

The aim of the study is to reduce the negative impact of sewage sludge from the production of cardboard and paper products on the soil by dewatering them with a dehydrator and preparing them for further disposal. Large-scale wastewater sludge from industrial enterprises during utilization is placed at disposal landfills which inevitably leads to a negative impact on the soil cover, littering of territories and withdrawal of the land fund from the economic turnover. In the course of the performed study, the well-known methods of dehydration of moisture-containing material were investigated and there was considered a technical solution to reduce the volume of formation of this type of waste using the example of cardboard and paper production. An electroosmotic installation is proposed, comprising an electrical insulation housing with electrodes: an anode made in the form of a current conductive cover and a cathode made in the form of a conductive perforated bottom of the housing which have a space between them for dehydrated waste. To study the process of sludge dewatering, a series of experiments was carried out on the dehydrator unit with variable voltage parameters between the electrodes. The results of the experimental study were the basis for statistical expressions of the mutual voltage influence between the electrodes, the duration of waste processing, the amount of removed moisture. A model has been obtained that describes the amount of moisture removed during waste treatment. The most productive operating mode of the installation, the time for treatment of waste portion have been established. It has been proven that with the help of an electroosmotic device, up to 70% of moisture is effectively removed from the volume of waste sludge. This makes it possible to significantly decrease their volumes, reduce areas for possible or temporary placement and reduce the ecological load on the environment.

The article analyzes the indicators of the gross harvest of potatoes in the Moscow region in recent years. It has been proven that an increase in acreage does not always lead to an increase in gross harvest. It is equally important to provide comfortable conditions for the growth and development of plants. Precipitation in the Moscow region in the spring and summer period falls extremely unevenly: days with heavy rains forming a layer of precipitation of tens of millimeters alternate with non-precipitating days and weeks. The necessity of additional irrigation to create an optimal water – air balance for the development of plants is substantiated and the advantages of using drip irrigation for these purpose which allows the delivery of irrigation water directly to the root zone of the plant are estimated. It is recommended to combine operations on the formation of potato ridges with the laying of a drip tape since in the initial period of development the plant has enough moisture reserves of the mother tuber and additional watering is not required. The design of the drip tape stacker based on the Grimme GF-75/4 ridge former has been developed to increase the degree of mechanization when laying the drip tape. At a working speed of 3.2…5.5 km/h the productivity of the machine was 0.51…0.97 ha/h. In the course of further research the irrigation rate was calculated taking into account the elliptical shape of the humidification contour which made it possible to exclude excessive watering. After the installation of the drip irrigation system, irrigation was carried out at a constant rate when the moisture capacity reached 70% of the uultimate field moisture capacity with the adjustment of the time between irrigations. The use of the drip irrigation system made it possible to increase the yield of potatoes of the varieties Red Scarlett and Zhukovsky Early by 26.5% … 28%, respectively.

Corner retaining walls are one of the most common structures of waterworks. Most of them were designed and built several decades ago and have been in operation for a long time. In some cases, there is a deviation from the design prerequisites and the strengthening of reinforced concrete structures of retaining walls is required. The main reason for these deviations is incomplete consideration of the characteristic features of retaining wall structures (including horizontal inter-block joints and secondary inclined cracks), as well as the nature of the loads acting on them. As a result, design horizontal transverse reinforcement is practically not installed in retaining walls that is not required by calculation based on traditional calculation methods.Traditional reinforcement schemes for retaining walls do not provide for the presence of horizontal inter-block joints and horizontal transverse reinforcement. As a result of the research carried out,the method for calculating the stress-strain state and strength of reinforced concrete structures of corner retaining walls with inter-block joints has been improved taking into account secondary stresses. Reinforcement schemes for retaining walls have also been improved.
