Sensitivity Analyses of the Seepage and Stability of Layered Rock Slope Based on the Anisotropy of Hydraulic Conductivity: A Case Study in the Pulang Region of Southwestern China
Authors: Xia Chengzhi , Lu Guangyin , Bai Dongxin , Zhu Ziqiang , Luo Shuai , Zhang Guangkeng
Published: August 2020

In the study of the seepage characteristics of layered rock slope under rainfall conditions, the majority of previous research has considered the hydraulic conduction to be isotropic, or only considered the anisotropy ratio of the hydraulic conductivity, ignoring the anisotropy angle. In the current study, a layered rock slope in the Pulang region was selected as an example. Then, based on the fitting parameters of the Van Genuchten model, pore water pressure sensitivity analyses of the layered rock slope were carried out. The anisotropy ratio and anisotropy angle were used to analyze the sensitivity of the seepage and stability of the layered rock slopes. The results show that as the anisotropy angle of hydraulic conductivity of layered rock slope decreased, the maximum volume water content of surface (MWCS) of layered rock slope gradually increased. Additionally, as the anisotropy ratio decreased and the anisotropy angle increased, the rising heights of the groundwater (RHG) of layered rock slope gradually increased. When the hydraulic conduction of layered rock slope was considered isotropic, the factor of safety (FS) tended to be overestimated. As the anisotropy ratio decreased and the anisotropy angle increased, the factor of safety (FS) of layered rock slope decreased. Prevention should be the objective for rock slopes with larger dip angles in the bedding plane in the Pulang region. This study provides feasible schemes for the evaluation of the seepage and stability of layered rock slopes in Pulang region of southwestern China.
Virtual Tracers to Detect Sources of Water and Track Water Reuse across a River Basin

Published: August 2020

Water managers around the world face the increasingly challenging task to evaluate the impacts of technological measures and policy mechanisms from the local to the river basin scale. A toolset providing quantitative, actionable information on dependencies and trade-offs between upstream and downstream water users is currently lacking. Yet, any intervention needs to be assessed in terms of consequences for downstream water users. This study evaluates the potential of a tracer-like approach, implemented in the water allocation software WEAP, to quantitatively track return flows and their downstream reuse in the river basin context. The WEAP-Virtual Tracer (WEAP-VT) approach was successfully applied to one of Europe’s driest river basins, the Segura River Basin in Spain. For each water demand site, the different original sources of water supply, dependency on upstream return flows, and downstream reuse of its return flow were assessed. Based on these results, agricultural, urban, and environmental water users were evaluated in terms of their suitability for water saving measures and their vulnerability to the reduction in upstream return flows. A scenario analysis simulating the improvement of local efficiency improvements shows that specific irrigation schemes and ecosystems become deprived of water. Hence, efficiency improvement in water-scarce basins should be considered with caution. The demonstrated ability to quantify key water reuse indicators for individual water users and at different aggregation levels makes WEAP-VT a valuable tool to support water resource management decisions.

In wastewater treatment plants, most microbial characterization has focused on bacterial, archaeal, and fungal populations. Due to the difficult isolation, quantification, and identification of viruses, only a limited number of virome studies associated with wastewater treatment plants have been carried out. However, the virus populations play an important role in the microbial dynamics in wastewater treatment systems and the biosafety of effluents. In this work, the viral members present in influent wastewater, mixed liquor (aerobic bioreactor), excess sludge, and effluent water of a conventional activated sludge system for the treatment of urban wastewater were identified. Viral members were observed by transmission electron microscopy and studied through next-generation sequencing studies. The results showed the dominance of bacteriophages in the viral community in all samples, with the dominant viral phylotype classified as Escherichia coli O157 typing phage 7. Moreover, different human viruses, such as Cynomolgus cytomegalovirus and Gammaherpesvirus, were also detected.

Published: August 2020

Seasonal water level fluctuations (WLFs) impose dramatic influences on lake ecosystems. The influences of WLFs have been well studied for many lake biotas but the microeukaryotic community remains one of the least-explored features. This study employed high-throughput 18S rRNA gene sequencing to investigate the spatiotemporal patterns of microeukaryotic communities in the dry and wet seasons with concomitant change of nutrients in Poyang Lake, which experiences huge seasonal WLFs. The results showed that the dry season and wet season had distinct microeukaryotic community compositions and structures. In the dry season, Ciliophora (13.86–40.98%) and Cryptomonas (3.69–18.64%) were the dominant taxa, and the relative abundance of these taxa were significant higher in the dry season than wet season. Ochrophyta (6.88–45.67%) and Chlorophyta (6.31–22.10%) was the dominant taxa of microeukaryotic communities in the wet season. The seasonal variation of microeukaryotic communities was strongly correlated to seasonal nutrient variations. Microeukaryotic communities responded significantly to dissolved organic carbon, total nitrogen, nitrate, and soluble reactive phosphorus in the dry season, and correlated to nitrate and total phosphorus in the wet season. The microeukaryotic community showed different modular structures in two seasons, and nutrient variations were the key factors influencing seasonal variations of the modular structures. Moreover, microeukaryotic community networks based on different seasons indicated that the microeukaryotic community co-occurrence patterns were not constant but varied largely associating with the nitrogen and phosphorus variations under the effects of WLFs. Our results are important for understanding how microeukaryotic communities respond to nutrient variation under seasonal water level fluctuation.
Estimating the Effect of Rain Splash on Soil Particle Transport by Using a Modified Model: Study on Short Hillslopes in Northern China
Authors: Wang Yanjun , Yang Fan , Qi Shenglin , Cheng Jinhua
Published: August 2020

Splash erosion is an important soil erosion process in sloping lands. This study aims to improve the model of rain splash transport based on the results of previous studies and field experiments involving rainfall simulation. A field study was conducted to examine the effects of rainfall properties, herbaceous cover and surface flow on splash processes on hillslopes in northern China. On the basis of the experimental results, a comprehensive model of rain splash was established through the quantitative analysis of the interactive effects of rainfall kinetic energy, vegetation coverage and overland runoff depth on splash erosion rate and the probability density of splashed particles and maximum splash distance. The results showed that the estimated and observed values of splash transport exhibit high consistency and adaptability. However, several discrepancies were observed between the estimated and observed values for events with high vegetation coverage. These differences can be ascribed to the variation in overland runoff connectivity and the differences in soil surface cohesion at various wetness degrees. The proposed model provides insights into splash erosion characteristics and suggestions for erosion control practices on hillslopes.
Special Issue “Public Policy Analysis of Integrated Water Resource Management”
Authors: Ingold Karin , Tosun Jale
Published: August 2020

Public policy analysis is interested in how policies emerge and develop in order to address societal problems. Issues related to water, such as the contamination of surface waters, floods, or plastic pollution in oceans are often highly complex, concern different jurisdictions, and require the collaboration of public and private actors. This complexity is addressed through integrated water management principles. However, these principles give room to open questions such as: what are the main challenges of policy analysis (research and practice) in terms of multi-level actor involvement (politics), cross-sectoral solutions (policies), and new institutional arrangements (polity)? To answer these questions, the seven papers of this Special Issue combine approaches borrowed from policy analysis with principles of Integrated Water Resources Management (IWRM). Each article tackles a complex, water-related problem and collectively, the papers present empirical evidence from case studies located around the world. We learn from all these analyses that adopting a policy perspective helps disentangling the procedural components of IWRM (the involvement of actors, the definition of the appropriate management area, the attribution of competences, etc.) from more substantial ones (like the development of a management plan and the implementation of measures). Addressing cross-sectoral and multi-level challenges is a difficult task, and policy analysis can help shedding light on both, the legitimacy of processes, and the effectiveness of their outputs and outcomes.
A Statistical Vertically Mixed Runoff Model for Regions Featured by Complex Runoff Generation Process

Published: August 2020

Hydrological models for regions characterized by complex runoff generation process been suffer from a great weakness. A delicate hydrological balance triggered by prolonged wet or dry underlying condition and variable extreme rainfall makes the rainfall-runoff process difficult to simulate with traditional models. To this end, this study develops a novel vertically mixed model for complex runoff estimation that considers both the runoff generation in excess of infiltration at soil surface and that on excess of storage capacity at subsurface. Different from traditional models, the model is first coupled through a statistical approach proposed in this study, which considers the spatial heterogeneity of water transport and runoff generation. The model has the advantage of distributed model to describe spatial heterogeneity and the merits of lumped conceptual model to conveniently and accurately forecast flood. The model is tested through comparison with other four models in three catchments in China. The Nash–Sutcliffe efficiency coefficient and the ratio of qualified results increase obviously. Results show that the model performs well in simulating various floods, providing a beneficial means to simulate floods in regions with complex runoff generation process.
Performances of the New HEC-RAS Version 5 for 2-D Hydrodynamic-Based Rainfall-Runoff Simulations at Basin Scale: Comparison with a State-of-the Art Model
Authors: Costabile Pierfranco , Costanzo Carmelina , Ferraro Domenico , Macchione Francesco , Petaccia Gabriella
Published: August 2020

The Hydrologic Engineering Centre-River Analysis System (HEC-RAS), developed by the US Army Corps of Engineers, is one of the most known, analyzed and used model for flood mapping both in the scientific literature and in practice. In the recently released version (release 5.0.7), the HEC-RAS model has been enriched with novel modules, performing fully 2-D computations based on the 2-D fully dynamic equations as well as the 2-D diffusion wave equations; moreover the application of rainfall to each cell of the two-dimensional domain is now possible. Contrarily to the common applications for flood propagation in river reach, this specific module has never been analyzed in the literature. Therefore, the main purpose of this work is to assess the potential and the capabilities of the 2-D HEC-RAS model in rainfall-runoff simulations at the basin scale, comparing the results obtained using both the options (fully dynamic equations and diffusion wave equations) to the simulations obtained by using a 2-D fully dynamic model developed by the authors for research purposes. Both models have been tested in a small basin in Northern Italy to analyze the differences in terms of discharge hydrographs and flooded areas. The application of a criterion for hazard class mapping has shown significant variations between the two models. These results provide practical indications for the water engineering community in the innovative research field related to the use of 2-D SWEs at the basin scale.
Comparing the Effects of Types of Electrode on the Removal of Multiple Pharmaceuticals from Water by Electrochemical Methods
Authors: Liu Yu-Jung , Huang Yung-Ling , Lo Shang-Lien , Hu Ching-Yao
Published: August 2020

Considering the lack of information on simultaneously removing multiple pharmaceuticals from water or wastewater by electrochemical methods, this study aimed to investigate the removal of multiple pharmaceuticals by electro-coagulation and electro-oxidation based on two types of electrodes (aluminum and graphite). The synthetic wastewater contained a nonsteroidal anti-inflammatory drug (diclofenac), a sulfonamide antibiotic (sulfamethoxazole) and a β-blocker (atenolol). The pharmaceutical removal with electro-oxidation was much higher than those with the electro-coagulation process, which was obtained from a five-cell graphite electrode system, while the removal of pharmaceuticals with aluminum electrodes was about 20% (20 µM). In the electro-coagulation system, pharmaceutical removal was mainly influenced by the solubility or hydrophilicity of the compound. In the electro-oxidation system, the removal mechanism was influenced by the dissociation status of the compounds, which are attracted to the anode due to electrostatic forces and have a higher mass transformation rate with the electro-oxidation process. Therefore, atenolol, which was undissociated, cannot adequately be eliminated by electro-oxidation, unless the electrode’s surface is large enough to increase the mass diffusion rate.
Clarice’s Secret. On The Foreign Legion (A legião estrangeira, 1964) by Clarice Lispector
Authors: Radulova Nadezhda
Published: August 2020

The 13 stories of the collection The Foreign Legion (A legião estrangeira, 1964), the first appearance of Clarice Lispector in Bulgarian, are a piece of hypnotic writing that is difficult to compare with any other writer’s language of that time. On the one hand, this prose has a memory of the European modernism with the experimental spirit of the Left Bank of the Seine, with elements of literary cubism and delicate traces of Judaic mysticism… On the other hand, the European refinement and suffistication are literally shaken by the local culture with its smell of jungle and its colorfully hysterical Latin American Catholicism.

Background

An epidemic of CKD in Central America predominantly affects males working in certain industries, including sugarcane. Urinary tract infections are commonly diagnosed among men in Nicaragua, who often receive antibiotics and nonsteroidal anti-inflammatory drugs for urinary symptoms.

Methods

We followed 251 male Nicaraguan sugarcane workers in seven job tasks over one harvest and measured urine dipstick parameters, kidney injury biomarkers, and eGFR. We administered a questionnaire about urinary symptoms, health-related behaviors, and medication history. We cultured urine in a subset of workers.

Results

The study population was composed of factory workers (23%), cane cutters (20%), irrigators (20%), drivers (16%), agrichemical applicators (12%), seeders/reseeders (6%), and seed cutters (4%). The mean age of participants was 33.9 years, and mean employment duration was 10.1 years. Cane cutters reported higher proportions of urinary-related symptoms compared with agrichemical applicators, irrigators, and seeders/reseeders. Seed cutters were more likely to take antibiotics (22%), whereas drivers and seeders/reseeders were more likely to take pain medications (27% and 27%, respectively). Proteinuria was uncommon, whereas dipstick leukocyte esterase was relatively common, especially among cane cutters, seed cutters, and seeders/reseeders (33%, 22%, and 21% at late harvest, respectively). Dipstick leukocyte esterase at late harvest was associated with a 12.9 ml/min per 1.73 m2 (95% CI, −18.7 to −7.0) lower mean eGFR and 2.8 times (95% CI, 1.8 to 4.3) higher mean neutrophil gelatinase-associated lipocalin. In general, workers who reported urinary-related symptoms had higher mean kidney injury biomarker levels at late harvest. None of the workers had positive urine cultures, including those reporting urinary symptoms and/or with positive leukocyte esterase results. Amoxicillin, ibuprofen, and acetaminophen were the most commonly used medications.

Conclusions

Job task is associated with urinary symptoms and dipstick leukocyte esterase. Urinary tract infection is misdiagnosed based on leukocyte esterase, which may be an important predictor of kidney outcomes.
Prácticas cuestionadas: acusaciones contra los oficiales de la justicia regia en el corregimiento de Murcia y Lorca a finales del siglo XV.
Authors: Membrado Sofia
Published: August 2020

Este artículo analiza las denuncias sobre los corregidores de las ciudades de Murcia y Lorca, de manera casi permanente a lo largo del reinado de los Reyes Católicos. Si bien se trató de un período marcado por importantes hitos normativos que buscaban moldear la institución del corregimiento, delineando atribuciones y deberes, así como faltas y castigos a las mismas, el proceso era incipiente y coexistía con otras tendencias. La percepción de aranceles, penas y multas que dictaban los corregidores al desempeñar su oficio de justicia da cuenta de esto. Aunque las normas establecían límites a estas prácticas, eran a la vez toleradas, permitidas y alentadas en algunos casos. De la observación de las acusaciones por esta materia y de su tratamiento obtenemos información relevante para caracterizar al corregimiento bajomedieval a través de la práctica de sus agentes.
La concesión de la ciudadanía romana por el emperador como acto de evergetismo

Published: August 2020

La concesión de la ciudadanía romana por el emperador tenía que responder a estrictos criterios de justicia, para evitar ser considerada un acto arbitrario, y por lo tanto tiránico. En este caso, la justicia dictaba que el fin de este favor imperial sólo podía ser el de incrementar el número de ciudadanos, lo que en sí mismo era un acto de evergetismo, pues proporcionaba un sólido fundamento a la res publica.
El irrealizado vicariato del amor: Jerónimo Gracián y la búsqueda de autoridad en el Carmelo descalzo post teresiano (1582-1614)
Authors: Macías Facundo
Published: August 2020

El presente artículo se adentra en la construcción de un lugar de autoridad ejecutada por el fraile Jerónimo Gracián dentro y fuera del Carmelo Descalzo tras el deceso de quien fuera su símbolo aglutinante, Teresa de Ávila (1515-1582). Tras un breve repaso por su vida y señalando su brusco ascenso y descenso desde la cúspide de la descalcez, nos detendremos en su intento por presentar un vínculo cercano con la visionaria de Ávila como elemento legitimador de su persona y obra. Finalmente, observaremos que el componente que Gracián presenta como eje unitivo entre él y Teresa se funda en la noción renacentista del amor platónico, haciendo del acto de amarla premisa de una autoridad vicaria que finalmente quedó más en el orden del anhelo que de la práctica.
Hierarchical Capillary Coating to Biofunctionlize Drug-Eluting Stent for Improving Endothelium Regeneration

Published: August 2020

The drug-eluting stent (DES) has become one of the most successful and important medical devices for coronary heart disease, but yet suffers from insufficient endothelial cell (EC) growth and intima repair, eventually leading to treatment failure. Although biomacromolecules such as vascular endothelial growth factor (VEGF) would be promising to promote the intima regeneration, combining hydrophilic and vulnerable biomacromolecules with hydrophobic drugs as well as preserving the bioactivity after harsh treatments pose a huge challenge. Here, we report on a design of hierarchical capillary coating, which composes a base solid region and a top microporous region for incorporating rapamycin and VEGF, respectively. The top spongy region can guarantee the efficient, safe, and controllable loading of VEGF up to 1 
μ
g/cm

in 1 minute, providing a distinctive real-time loading capacity for saving the bioactivity. Based on this, we demonstrate that our rapamycin-VEGF hierarchical coating impressively promoted the competitive growth of endothelial cells over smooth muscle cells (ratio of EC/SMC~25) while relieving the adverse impact of rapamycin to ECs. We further conducted the real-time loading of VEGF on stents and demonstrate that the hierarchical combination of rapamycin and VEGF showed remarkable endothelium regeneration while maintaining a very low level of in-stent restenosis. This work paves an avenue for the combination of both hydrophobic and hydrophilic functional molecules, which should benefit the next generation of DES and may extend applications to diversified combination medical devices.
The Diaspora Chinese Gospel: Pursuit of Success on Philippians 3:7-14
Authors: Gong Rev. Wenhui
Published: August 2020

Traditional Western guilt-based culture evangelical tools are not effective when reaching out to non-Western people ingrained with an honor/shame culture, such as the Diaspora Chinese. This in-depth exegesis of Philippians 3:7-14 from the standpoint of Paul's pursuit of success, along with personal testimony, stories, and experiences from the author's life, presents a culturally relevant perspective to reach Diaspora Chinese for the Gospel.
The goal of Paul's pursuit was a personal relationship with Jesus Christ, not worldly success. The way of his pursuit was to achieve righteousness through faith in Christ. The difference in emphasis between sin in a guilt-based culture and righteousness in an honor/shame culture is an important distinction. Paul continued his pursuit by pressing on to reach others with the message of relationship and righteousness with Christ. He focused on "one thing," the prize, his missions to reach others with the Gospel message.
The Gospel message must be contextualized for the recipients but the core must never change. Contextualization is the dynamic process to deliver the Gospel message in a concrete cultural situation.

Intertextuality, as a cross-linking of one meaning with another, refers to the link with other texts and the contributions they make to offer various interpretative and creative possibilities. It is considered a central element of the complexity of conceptual and semantic relationships to give meaning to communication, it incorporates and validates the culture of the subject in the democratization process in order to understand and participate in it. This research was carried out graduates of regular basic education to measure the domain of intertextuality, two prose readings were used, both by the writer and poet César Abraham Vallejo Mendoza, (1) Los Caynas, and (2) Beyond life and death, for the collection of information observable and measurable behavioral indicators were chosen, observation and a checklist were used. It was found that 62.1% was at the low level, 29.3% at the high level and 8.6% at the medium level. It is recommended that in future investigations, representative samples be used to compare and explain the literary competence and reading experience that would be basic elements of intertextuality.

Authors: Devdoss Prem Kumar , Srinivasa Rao H Prasanna
Published: August 2020

Objective:
The objective of this retrospective study is to identify the elimination half life of CA 125 biomarker in women receiving neoadjuvant chemotherapy for newly diagnosed advanced epithelial ovarian cancer at our centre and develop it as a surrogate marker of response to chemotherapy.

Methods:
Medical records of women who were newly diagnosed with inoperable advanced ovarian cancer stages III and IV at our centre were selected. Only people with completely documented records in the years 2017 & 2018 were selected. Clinical information on age, menopausal status, BMI, radiological PCI, stage, histology, chemotherapy drugs used, CA 125 levels before and after neoadjuvant chemotherapy were noted and information analysed.
Only 40 patients were identified meeting all required criteria.
The patients were divided into 3 sets based on CA 125 elimination half life group 1(t ½ < 10 days), group 2 (t ½ 10- 20 days) and group 3 (t ½ > 20 days). The base line characters and outcomes of surgery and pathological responses were compared between these groups.
Results:
Optimal cytoredcution was possible in 19/21(90.4%) patients in group 1, 6/10(60%) in group 2 & 2/9(22.2%) in group 3. Clinical complete response was found in 12/21 (57.1%), 2/10(20%) & 0/9(0%) respectively. Progressive disease was noted in 4/9(44%) of group 3 patients. There was striking differences between the groups with respect to clinical and pathological response.
Conclusion:
In summary, CA 125 elimination half life measurement is a reproducible tool that can be used to assess chemotherapy sensitivity in patients with newly diagnosed advanced ovarian cancer following neoadjuvant chemotherapy. The CA 125 half life value is a helpful measurement that allows the clinicians to measure the degree of chemosensitivity prior to cytoreductive surgery.

A Low-Complexity Modulated Model Predictive Current Control Scheme for PMSM based Starter Generator Control System in More Electric Aircraft
Authors: Wang Qi , Yu Haitao , Li Chen , Yeoh Seang Shen , Lang Xiaoyu , Yang Tao , Rivera Marco , Bozhko Serhiy , Wheeler Patrick
Published: August 2020

Modulated model predictive control (M2PC) has recently emerged as a possible solution for control in starter generator systems in the more electric aircraft (MEA), due to its advantages of fixed switching frequency, fast response and good performance. However, conventional M2PC requires the prediction of each possible output voltage vector, which involves a heavy computational burden for the processor, especially for multilevel converters. This is an obstacle for practical industrial applications. To solve this problem this paper introduces a new, low-complexity modulated model predictive control (LC-M2PC) for a starter generator control system with a neutral point clamped (NPC) converter. The proposed LC-M2PC only needs prediction action once in each control interval, which can reduce the computational burden of processor. Fixed switching frequency is maintained and it can achieve a lower total harmonic distortion (THD) current than conventional M2PC, using space vector modulation (SVM). This proposed LC-M2PC method is validated on a prototype electrical starter generator (ESG) system test rig with three-level NPC converter. Experimental results verify the effectiveness of the proposed method.

Published: August 2020

The possibility for using of surface plastic deformation when applying ultrasonic vibrations to the instrument
to form microgeometric state of the parts surface made of copper M1 and aluminum alloy D16 are studied. Two
ultrasonic machining schemes are compared: when the direction of vibration is normal to the surface of the part
and tangent to this surface. It is shown that the use of tangent scheme changes the interaction nature of the tool
with the surface of the part and the trajectory of the tool motion. It is established that the angle β between the direction
of the rotation speed vector of the part and the vibration speed vector of the tool significantly affects on the
microgeometry being formed. Therefore, angle β together with the main motion speed, feed, static load, frequency
and amplitude of the tool’s vibrations, is technological parameter that extend the capabilities of tangential scheme
in surface roughness forming. It is revealed that processing according to this scheme allows escaping the intensive
flow of material in the deformation zone and the formation of waves on the surface of the part.
Relations entre les débits liquides et les flux de matières en suspension dans la haute Tafna : cas de la partie amont du sous-bassin versant de l’oued Sebdou (Nord-Ouest algérien)

Le présent article se concentre sur les phénomènes de crues qui engendrent un transport solide en suspension abondant, dans la haute Tafna (partie amont du bassin versant de l’oued Sebdou). Afin de mieux comprendre la dynamique sédimentaire dans ce bassin versant, on s’est basé sur l’exploitation des données des couples de débits liquides et des concentrations en matières en suspension à l’échelle instantanée, fournies par l’Agence nationale des ressources hydriques (ANRH). On a choisi les crues les plus importantes et les plus représentatives sur une période de 30 ans allant de 1970 à 2000, afin d’établir les relations d’hystérésis qui permettent de faire une classification en cinq catégories, présentant ainsi des dynamiques de transfert très différentes selon les crues. Les résultats obtenus dans ce travail ont montré l’existence de cinq classes de crue, celles qui dominent sont celles de la classe 2, avec une hystérésis de forme boucle ouverte sens horaire (sens des aiguilles d’une montre), elles se manifestent surtout en hiver et au printemps. Par ailleurs, les crues de la classe 3 qui présentent une hystérésis de forme boucle ouverte sens antihoraire (sens contraire des aiguilles d’une montre), apportent les valeurs maximales des flux solides et liquides, soit 37 % des charges en matières en suspension contre 29 % de flux liquide, tout en se manifestant par le même nombre de crues, sept durant l’automne, le printemps et l’été.

Повседневная жизнь советского прошлого рождала культурные коды и поведенческие стереотипы, которые вызывают сегодня не только ностальгические воспоминания людей, рожденных в СССР, но и заслуженный интерес новых поколений, все более увлекающихся антропологией советскости.

Everyday life of the Soviet past brought into the world cultural codes and behavioral stereotypes, which today evoke not only nostalgic memories of people born in the USSR, but also the time-honored interest of new generations, who are are attracted by the anthropology of Sovietism.
