Wuhan city in Hubei Province is endowed with unique natural water resources and numerous lakes. It has a good framework of natural “green sponge”, which provides a broad space for stormwater regulation and storage. However, with the increase of infrastructure construction in Wuhan, many lakes have been buried and the city is becoming a “hard shell city” made of steel and cement. This article combines the natural landform of Wuhan and the pocket park system theory to make an organic combination of the ongoing urban infrastructure construction and the restorative construction of the municipal water supply system in Wuhan, so as to make an exploratory research for the early construction of Wuhan into a sponge city.

AbstractIn the attempt to foster circular economy (CE), cities are increasingly adopting urban living labs (ULLs) as sites of co-production aimed at testing alternative solutions based on the reuse of products, reduction of consumption and recycling of materials. Taking this perspective, our study adopts an exploratory research design to discover the pragmatic implications emerging from a case study. The City of Turin joined proGIreg, a European project that entails the regeneration of former industrial districts by means of nature-based solutions (NBS). Ranging from aquaponics to green roofs, seven NBS have been experimented in Turin, which rely on the use of natural systems to tackle social, economic and environmental challenges efficiently and sustainably. Among them, the most promising is related to the production and test of the ‘new soil’, a blend obtained by mixing earth materials coming from construction sites with compost, zeolites and mycorrhizae. The case herein presented is interesting to analyse for the multi-stakeholder management setting used, where public institutions, private companies, research institutions, citizens and associations collaborated in the co-creation and testing phase of the NBS. Consequently, the data collected through participant observation and direct interviews allow researchers to describe multi-stakeholders’ dynamics and how they work. Thus, this paper narrates a micro-contextual experience while providing a critique. Results include an analysis of the unique combination of different stakeholders, which strongly impacted on the management and the effectiveness of the entire project. By consequence, the paper offers both theoretical contributions to the relational branch of stakeholder theory and practical evidence in demonstrating the importance of the relational branch of the theory over a more traditional transactional view.

The relevance of multidimensional and porous crystalline materials to nuclear waste remediation and storage applications has motivated exploratory research focused on materials discovery of compounds, such as actinide mixed-oxoanion phases, which exhibit rich structural chemistry. The novel phase K1.8Na1.2[(UO2)BSi4O12] has been synthesized using hydrothermal methods, representing the first example of a uranyl borosilicate. The three-dimensional structure crystallizes in the orthorhombic space group Cmce with lattice parameters a = 15.5471(19) Å, b = 14.3403(17) Å, c = 11.7315(15) Å, and V = 2615.5(6) Å3, and is composed of UO6 octahedra linked by [BSi4O12]5− chains to form a [(UO2)BSi4O12]3− framework. The synthesis method, structure, results of Raman, IR, and X-ray absorption spectroscopy, and thermal stability are discussed.

This paper presents a framework of objectives and indexes for sponge cities implementation in China. The proposed objectives and indexes aims to reflect whether the city is in accord with the sponge city. Different cities have different objectives and indexes as each city has its own geologic and hydrogeological conditions. Therefore, the main problems (e.g., water security and flood risks) in the central urban area of Changzhou city, China were evaluated scientifically. According to the local conditions, four objectives and eleven indexes have been made as a standard to estimate the sponge city and set a goal for the city development to reach the goal of sustainable urban development. The strategy of process control was implemented to improve the standard of urban drainage and flood control facilities, regulate total runoff and reduce storm peak flow, and the ecological monitoring of the function of the rivers and lakes. The objectives of sponge cities include water security, water quality improvement, healthy water ecosystems, and water utilization efficiency. Urban flood prevention capacity, river and lake water quality compliance, and annual runoff control are the key objectives to encourage the use of non-conventional water resources.

In this article we intend to analyze what is the state of the art in which the São Paulo City is in relation to the concept of Mil Cities, instituted in 2018 by UNESCO. From a group of metrics developed by the institu­ tion, we intend to see and measure effective actions that have already been implemented or are under development, that can serve as a basis to enable the construction of a MIL City in the analyzed public institu­ tion. In this tracking we want to understand how public communication from the perspective of public interest can establish itself as a paradigm, when governments, organizations and society demand a new and higher level of interlocution and exchange, with the purpose of transforming reality for a project that can transform the city of São Paulo into a MIL City. We use exploratory research in primary and secondary sources as a methodology.

As the number of favelas and poor residents of Rio de Janeiro grew quickly by the mid-20th century, they became the object of policymaking, social science research, real estate speculation, and grassroots mobilization. After a decade in which local authorities recognized the de facto presence of favelas but without legally ascertaining the right of permanence, the 1960s and early 1970s witnessed the era of mass eradication. Seemingly contradictory—but complementary—policies also included the development of massive low-income housing complexes and innovative community development and favela urbanization experiences empowered by community organizations with the assistance of experts committed to improving the lives of poor Cariocas (residents of Rio). Favelas in Rio were at the crossroads of a particular interplay of forces: the urgent need to modernize Rio’s obsolete and inadequate urban infrastructure; the new administrative status of the city after the inauguration of Brasilia; and the redefinition of the balance of power between local, municipal, and federal forces in a time of radical politics and authoritarian and technocratic military regimes, Cold War diplomacy, and the transnational flows of expertise and capital.

Развитие торговли и экономических связей привело к необходимости строительства специальных заведений, предназначенных для торговцев, путников, с помещениями для вьючных животных. Это в свою очередь привело к появлению постоялых дворов. У каракалпаков постоялый двор назывался шарбақ. Он были двух видов: для кратковременного пребывания, расположенный в черте города недалеко от базара, и долговременного пребывания, устанавливавшийся при въезде в город. Второй из них предпочитали путешествующие издалека. Посетители же первых постоялых дворов останавливались в нем для разгрузки привезенного для продажи товара, реализовав который в течение дня, покидали заведение. Функции шарбақ заключались не только в предоставлении приюта, возможности отдыха, размещения товаров и животных, но и в общении, обмене новостями. В базарные дни сюда стекались жители со всей округи для того, чтобы узнать последние новости. Для старшего поколения шарбақ был, в первую очередь местом проведения досуга. Постоялый двор играл важную роль в жизни каракалпаков. Об этом свидетельствует их количество. К середине XX века постоялый двор начинает терять свою значимость в связи с развитием городской инфраструктуры и появлением гостиниц. The development of economic ties entailed arranging special establishments for traders and travelers, with premises for beasts of burden. This resulted in the construction of hostelries. The Karakalpaks called them sharbak. There were two types of sharbaks: located within the city near the bazaar, intended for a short stay, and installed at the entrance of the city for the long-term visitors. Travelers from far away preferred the second type. Guests of the first type of hostelries usually stayed there just to unload the goods and sell them at the bazaar during the day. The sharbaks not only provided shelter, recreation, and accommodation of goods and animals, but also served as a place for communication and news exchange. On market days, residents from all over the area flocked there to find out the latest news. For the older generation, sharbak was a place of leisure. The hostelry played an important role in the social life of the Karakalpaks, which is evidenced by their large number. By the middle of the 20th century, the sharbak began to lose its significance due to the development of urban infrastructure and modern hotels

The city of Aripuana is one of the largest wood producer in the state of Mato Grosso, Brazil. Wood residues are used in the electricity generation at three thermoelectric plants in this region. However, the plants have high costs in transporting the wood residues (due to poor road conditions). Hence, this paper compares the energy performance of wood residues in natura and compacted as briquettes by calculating the heating value and determining the influence of moisture content on the energy characteristics of wood residues. The goal is to demonstrate the viability of using briquettes in order to improve thermoelectric generation. The wood residues from this region are affected by the high humidity of the biome. An alternative to improve the use of energy contained in the wood residues is to produce briquettes with lower humidity. This allows one to maintain high levels of heat energy in a lower volume, facilitating handling and storage. The results show that the use of briquettes improved the performance of thermoelectric plants, generating 1 MW of electricity power with less than 1 ton of briquettes. This contributes to the preservation of the environment, reducing operating costs, transportation and storage of the raw materials.

Modern urban youth sports cultures are notable for their diverse and complex nature. The question arises as to what analytical approach should be used to study their multifaceted character. Using the St Petersburg skateboard scene as an example, the article shows the advantages in applying the concept of the post-sport cultures to understand how the common functions of urban infrastructure are redefined, what trends exist on the scene, how they shape the meanings attributed to them by the scene participants, and how those signs are read.  The study also employs the solidarity approach to describe the interactions between the scene participants through the ideas and ideological controversies shared by them. The focus of the paper is how to apply solidarity approach to study the nature of urban post-sport cultures based on St Petersburg skateboard scene case study. Given the lack of Russian publications on the topic, the study is also aimed at inscribing the Russian skateboarding experience into the Western academic context.

This article looked at the quantity and storage time of attiéké produced and sold in the town of Daloa. It also examines the microbiological characteristics of attiéké-femme and attiéké-garba from this locality during storage. The study was carried out on the one hand through a field survey carried out on the producers and sellers. On the other hand, a sample was taken from 10 sellers of attiéké-garba and 10 sellers of attiéké-woman. The study found that the women producers sell 87% of their production in the city of Daloa and export 13%. In addition, attiéké can be kept for 2 days at the producers and beyond 2 days at the sellers before their stock runs out. Therefore, a weekly production of more than 200 kg for the majority of the producers is observed. Microbiological analyses showed high levels of germs (MAG: 6.106 CFU/g; Yeasts and moulds: 2.7.106 CFU/g) for attiéké-women and (2.106 CFU/g of GAM and 1.6.103 CFU/g of Yeasts and moulds) for attiéké-garba. Total coliforms and faecal coliforms were only found in attiéké-women. No salmonella was observed. In view of the results, it should be noted that female attiéké is the most contaminated type of attiéké.
