A Europe-wide inventory of citizen-led energy action with data from 29 countries and over 10000 initiatives.

Numerous case studies show that citizens engage in various ways in renewable and low carbon energy projects, thereby contributing to the sustainable energy transition. To date, however, a systematic and cross-country database on citizen-led initiatives and projects is lacking. By performing a major compilation and reviewing copious data sources from websites to official registries, we provide a Europe-wide inventory with over 10,000 initiatives and 16,000 production units in 29 countries, focusing on the past 20 years.

[Pathogenesis of arthrosis deformans of the knee joint].

The authors have studied the biochemical characteristics (type, aminoacid composition, carbohydrate component content) of the collagene proteins in the articular cartilage in normal conditions and in various expression of deforming arthrosis of the knee joint. The results (collagen of the its type formation, disturbances in the aminoacid composition of collagen of the 1st and 2nd types, changes in the carbohydrate component content, accumulation of procollagen of type 2) allowed to suggest that already at the early stages of development of deforming arthrosis there are distortion of synthesis and disturbance in postsynthetic transformations of the collagen proteins of hyaline cartilaginous tissue which lead to disturbances in the structure and in the function of the matrix and progressive degradation of the articular cartilage.
