The effectiveness of the use of a light-transforming shelter of vegetation structures consisting of a polypropylene spunbond with an organic photoluminophore integrated into its structure during the rooting of physiologically active stem cuttings of Hungarian lilac was studied. The object of the study was reproductively mature Hungarian lilac plants located in the arboretum of the Nizhny Novgorod State Agricultural Academy with geographical coordinates 56°14'32.7” N 43°57'20.7”E. The unequal reaction of the tested samples of Hungarian lilac to the use of luminophore in the shelters of vegetation structures during the rooting of cuttings was established, which manifested itself in all characteristics of regeneration processes. High rates of callus formation were in the shelter variants with a higher concentration of luminophore: 73.16 ± 5.95% and 65.25± 4.80%. Lower than in other shelters, the result was recorded in the variant with the lowest luminophore density: 47.00 ± 3.62%.

Abstract In this work, mechanism and conformation changes of cellulose regenerated from ionic liquid by anti-solvents (water, ethanol and acetone) were investigated by molecular simulations. Cellulose model consists of seven glucose single chains were constructed. In order to depict the regeneration mechanism, both the dissolution and regeneration processes of cellulose in [Bpy][OAc] IL were simulated. The methyl hydroxyl group of cellulose will change its conformation during dissolution and regeneration. The conformation of initial cellulose crystal is mainly the tg conformation. After dissolved in ILs, the cellulose conformation changes into the gt conformation and the gg conformation. After regenerated by anti-solvent, the proportion of the gg and gt conformation changes, and the gg conformation increased and the gt conformation decreased. Based on energy analysis, it is concluded that the energy for tg is the lowest, and the tg widely exists in cellulose I. After cellulose is dissolved in ILs, the conformation changes into two higher energy conformations, the gt and gg. In the subsequent regeneration process, with the completion of regeneration, the gg conformation increases and the gt conformation decreases.

According to the current European scenario, cultural, creative, and community-led policies play an increasingly important role in influencing local resources, systems, and infrastructures management and demand a novel approach in governing, financing, and monitoring urban regeneration processes. Therefore, cities become contexts where cultural and creative practices can be implemented, integrating social cohesion principles based on communities, shared values, and collaborative decision-making approaches, with particular attention to enhancing cultural heritage, mainly unused or underutilised. The purpose of this research is to explore how the Cultural and Creative Cities Monitor (CCCM) methodological framework, developed by the Joint Research Centre of the European Commission, can be integrated at the local scale to assess the impacts of urban regeneration processes in an interactive and dynamic way, through the data emerging from the monitoring of urban regeneration experiences activated with the communities. The paper describes the “Play ReCH (Re-use Cultural Heritage)” approach, that promotes a process of collaboration, gamification, and innovation in cultural heritage reuse, as an opportunity to test how cultural, creative, and community-led urban strategies can support the enhancement of heritage generating enabling environments and culturally vibrant contexts. The Play ReCH approach and the “Hack the City Salerno” mission, activated in the Salerno historic centre (Italy), open the reflection on some relevant issues related to how citizens become makers of cultural and creative cities’ policies, and contribute to evaluating and monitoring their implementation at diverse urban scales. The Play ReCH mission underlines how new evidence suggests declining the CCCM conceptual framework and related urban policies assessment, co-defining suitable community-based indicators.

Abstract Within the last decades, the reorganisation of the Armed Force left many voids in the territories. Being located in highly lucrative and desirable locations, former military sites can be redeveloped into either profit-driven spaces or proper urban commons. This paper focuses the attention on the Italian case and scrutinises former military barracks in the dichotomies between the generation of profit-driven spaces and urban commons. Also, the analysis questions the actual role of these voids in guaranteeing the right to the city, especially in times of severe shortage of public resources to undertake urban regeneration processes.

This paper reflects on Common-places (2019), a project that was developed in Sheffield on the invitation of Site Gallery to participate in their ‘City of Ideas’ programme. Amidst the urban regeneration processes that are reshaping the city, this programme offered the opportunity to think about novel approaches that art and interdisciplinary practices could bring to processes of urban change. Common-places was proposed as a participatory workshop that engaged the local community, by inviting them to recognise the things they ‘hold dear’ about the areas in which they live or work. The premise was to identify forms of material and immaterial value that would reveal the ‘character’ of a place and its forms of use-value that are important to a local community. The intention was to develop a set of tools to highlight, map, commemorate and ultimately protect this intangible heritage in the context of urban regeneration in Sheffield. The project addressed some of the existing challenges of integrating an expanded notion of heritage in urban planning. Moveover, it reflects on the importance of identifying the use-value of intangible heritage and embraces a more integral and holistic approach to city planning.

The deployment of photocatalysis for remediation of water has not yet been realized, although laboratory-scale studies have demonstrated promise. Accomplishing this requires the development of photocatalysis as a process, including studying its efficiencies in remedying water when high volumes of water are processed, and addressing the recovery, possible regeneration and reuse of the photocatalysts. To that end, this work is aimed at demonstrating the use of a custom-built mobile platform for disinfecting large quantities of water. The benchtop platform built is capable of processing 15.14 L (4 gallons) per minute of water, with possibility for further scale-up. Preliminary studies on the catalyst recovery, regeneration and reuse via gravity-assisted settling, centrifugation and air plasma treatment indicated that 77% of Aeroxide® P25 titania (TiO2) nanoparticle and 57% of porous TiO2 nanowire photocatalysts could be recovered and regenerated for further use. Overall, this study indicated that process improvements, including increasing the kinetics of the photocatalysis, and optimization of the efficacies of the catalyst recovery and regeneration processes will make it useful for water remediation on any scale. More importantly, the portable and flexible nature of the benchtop photocatalysis system makes it amenable for use in conjunction with existing technologies for remedying large quantities of water.

Functional hypothalamic amenorrhea (FHA) is a very common condition affecting women of procreative age. There are many reasons for this disorder, including a low availability of energy in the diet, low micro- and macronutrient intake, overly intensive physical activity, disturbed regeneration processes, sleep disorders, stress, and psychological disorders. The main determinant is long-term stress and an inability to handle the effects of that stress. FHA is a very complex disorder and often goes undiagnosed. Moreover, therapeutic interventions do not address all the causes of the disorder, which could have implications for women’s health. As shown by scientific reports, this condition can be reversed by modifying its causes. This review of the literature aims to update the current knowledge of functional hypothalamic amenorrhea and underscores the complexity of the disorder, with particular emphasis on the nutritional aspects and potential interventions for restoring balance.
