Gooseberry is one of the common berry crops in Siberia. But despite its merits, the gooseberry is characterized by a weak development of plant phytomass when propagated by stem cuttings, and as a result, a decrease in the quality of planting material. The results of studies of various backgrounds of non-root fertilizing showed that the variant using exogenous treatments of Zn 1% + Cu 1% + 6 micronutrient elements showed an increase in the area of the leaf blade to 12.9 cm2. The accumulation level of copper, zinc, manganese and cobalt on plots using leaf fertilizing exceeded the control. Non-root feeding of Zn 1% + Cu 1% + 6 micronutrients of gooseberry when growing planting material by the green cuttings method increases the level of micronutrient accumulation (Zn, Co, Mn) in the leaves and activates growth processes – contribute to the development of assimilation surface.

Subject. The study addresses the improvement of risk management efficiency and the quality of lending decisions made by banks. Objectives. The aim is to present the bank management with a fair algorithm for risk management motivation on the one hand, and the credit management (business) on the other hand. Within the framework of the common goal to maximize risk-adjusted income from loans, this algorithm will provide guidelines for ‘risk management’ and ‘business’ functions on how to improve individual and overall efficiency. Methods. The study employs the discriminant analysis, type I and II errors, Lorentz curve modeling, statistical analysis, economic modeling. Results. The paper offers a mechanism for assessing the quality of risk management decisions as opposed to (or in support of) decisions of the lending business when approving transactions. The mechanism rests on the approach of stating type I and II errors and the corresponding classical metric of the Gini coefficient. On the ‘business’ side, the mechanism monitors the improvement or deterioration of the indicator of changes in losses in comparison with the market average. Conclusions. The study substantiates the stimulating ‘rules of the game’ between the ‘business’ and ‘risk management’ to improve the efficiency of the entire business, to optimize interactions within the framework of internal competition. It presents mathematical tools to calculate corresponding indicators of the efficiency of internally competing entities.

We share our experience on the implementation of a multidisciplinary aerodigestive program comprising an aerodigestive team (ADT) so as to evaluate its feasibility. We performed a retrospective chart review of the patients discussed at the monthly ADT meetings and analyzed the data. A total of 98 children were referred to the ADT during the study period. The number of cases increased steadily from 3.5 cases per month in 2019 to 8.5 cases per month in 2020. The median age of patients was 34.5 months, and 55% were male. Among the chronic comorbidities, neurologic disease was the most common (85%), followed by respiratory (36%) and cardiac (13%) disorders. The common reasons for consultation were suspected aspiration (56%), respiratory difficulty (44%), drooling/stertor (30%), regurgitation/vomiting (18%), and feeding/swallowing difficulty (17%). Following discussions, 58 patients received active interventions, including fundoplication, gastrostomy, laryngomicrosurgery, tracheostomy, and primary dilatation of the airway. According to the questionnaire of the caregiver, the majority agreed that the main symptoms and quality of life of patients had improved (88%), reducing the burden on caregivers (77%). Aerodigestive programs may provide comprehensive and multidisciplinary management for children with complex airway and digestive tract disorders.

In Italy, after the introduction of the Code of Cultural Heritage and Landscape in 2004, the Regional Landscape Plan (RLP) has acquired a coordination role in the urban planning system, for the implementation of policies for landscape protection and valorisation. The case study of the RLP of Sardinia is a paradigmatic application to the coastal area of the island, which is considered most vulnerable and subject to settlement pressure. The objectives of preservation and valorisation of the territorial resources should be transferred into local planning instruments by adopting strategies aimed at the preservation of the consolidated urban fabric, at the requalification and completion of the existing built-up areas according to the principles of land take limitation and increase in urban quality. The paper investigates the state of implementation and the level of integration of landscape contents in the local plans that have been adapted to the RLP, using a qualitative comparative method. In addition, the results of the plan coherence checks, elaborated by the regional monitoring bodies after the adaptation process, have been analysed to identify the common criticalities and weaknesses. The results highlight the lack of effectiveness of the RLP, after more than a decade since its approval, considering the limited number of adequate local plans and the poor quality of their analytical and regulative contents in terms of landscape protection and valorisation. Conclusions suggest some possible ways to revise the RLP, focusing on the participation of local communities and the development of a new landscape culture.

The knowledge of the topological structure and the automatic fare collection systems in urban public transport produce many data that need to be adequately analyzed, processed and presented. These data provide a powerful tool to improve the quality of transport services and plan ahead. This paper aims at studying, from a mathematical and statistical point of view, the Barcelona metro network; specifically: (1) the structural and robustness characteristics of the transportation network are computed and analyzed considering the complex network analysis; and (2) the common characteristics of the different subway stations of Barcelona, based on the passenger hourly entries, are identified through hierarchical clustering analysis. These results will be of great help in planning and restructuring transport to cope with the new social conditions, after the pandemic.

Unsatisfactory quality of root canal treatment is one of the most important problems of modern dentistry. One of the reasons is the limited knowledge of dentists about the regional features of the endodontic teeth anatomy, which is becoming particularly relevant in the rise of migration activity of the Russian population. But compared to other countries, there are very few studies and publications in this field in Russia. Objective. Study the features of first molars' root canals' anatomy in patients from different regions of Russia. Materials and methods. 363 cone-beam computed tomography (CBCT) scans of the jaws of patients 26 to 64 years of age, living in Moscow and StPetersburg for at least four generations have been considered. The endodontic anatomy of 347 first molars of the upper and 611 lower jaws was studied. The number of roots and root canals, their structure and shape were determined. Results. Anatomical differences in the structure of the first molars' root canals were established in residents who resided in Moscow and StPetersburg for several generations. Variations in the number of roots and root canals were found in the upper jaw molars. As for the canal-root system of the lower molars, most often they were characterised by different variants of the cross-section and the number of canals in the distal root. Conclusions. The results of the study can be used in practical dentistry, as they allow the dentists of StPetersburg and Moscow to expand the current understanding of the root system structure and the frequency of possible variations in these regions.

Creative participation refers to citizens’ invention of, and engagement in, new action forms that aim to influence, or take responsibility for, the common good in society. By definition, these action forms are constantly evolving and cannot be listed or summarized. Yet some, like guerrilla gardening, have over time become more established in political repertoires, and specific arenas are known to be particularly productive sites for their development. These include in particular the Internet, and lifestyles and consumption. The constant changes in how citizens become active represented by creative participation present considerable challenges for scholars of political participation—both in terms of theory and methodology. In particular, such forms test our ability to distinguish political from nonpolitical activities. However, how political creative participation is, is often subtle and implicit, and therefore hard to establish. Yet being able to do so is essential for an ongoing assessment of the quality of participatory democracy. With conventional forms of participation declining and creative participation becoming more common, scholars must be able to agree on definitions and operationalizations that allow for the comparison of participatory trends. For instance, a key concern has been whether creative forms of participation crowd out more conventional ones, like voting or lobbying politicians. Developments in survey research have been able to show that this is not the case and that creative participation may in fact increase conventional participation. In addition, qualitative research methods like focus groups and ethnography, allow for more open-ended explorations of this elusive research topic. As to who participates, creative participation has enabled traditionally underrepresented groups like women and young people to catch up with, and sometimes overtake, those older men who have long dominated conventional political participation. Still, education remains a key obstacle even to creative participation. The COVID-19 crisis that took hold of the world in 2020 has compromised access to collective action and public space. It has thereby once more put the onus on citizens to engage creatively with ways to influence, and take responsibility for, society. At the same time, the crisis presents a need and opportunity for political participation scholarship to engage more deeply with theoretical debates about what it means to be political or to participate.

The first experience of transplanting large-sized coniferous dendrointroducents (Picea glauca (Moench) Voss, Larix sibirica Ledeb.) in the spring-summer period without preliminary prepara-tion of the root system in the urban conditions of the Polar region was presented. Four specimens of middle-aged plants of both species were selected. The transplant was carried out with the max-imum use of mechanized equipment, which ensures good preservation of the lump and the tree it-self. There were four mutually related stages of work (preparatory, digging out plants, transporta-tion, planting), the quality of which depends on the success of plant survival. A brief description of the decorative qualities, morphometric parameters and the state of the experimental plants has been given. It has shown that due to the peculiarities of the soil and the location of the root system in coniferous introduced species, a clod of earth should be at least 60 cm thick, with a diameter of 110 to 130 cm. The main agrotechnical methods for the creation and care of plantings from large-sized plants were given.
