Lactic acid (LA) is an organic compound used in several industries, such as food, textile, chemical, and pharmaceutical. The global interest  in  this  product  is  due  to  its  use  for  the  synthesis  of  numerous  chemical  compounds,  including  polylactic  acid,  a  biode-gradable thermoplastic and substitute for petroleum-derived plastics. An in-depth overview of the use of industrial and household wastes as inexpensive substrates in order to reduce the cost of LA production is presented. A review is carried out of the biotech-nological aspects that must be taken into account when using some wastes with high transformation potential to produce LA in a submerged  culture,  as  well  recommendations  for  their  use.  The  advantages  and  disadvantages  of  different  types  of  treatments used for the transformation of waste into suitable substrates are considered. Several methods of fermentation, as well as genetic strategies for increasing the production, are summarized and compared. It is expected that in a few years there will be many ad-vances in these areas that will allow greater large-scale production of LA using agroindustrial or household wastes, with potential positive economic and environmental impact in some regions of the planet.

The article analyzes the evaluation of the transformation potential of valuable urbanised landscape. Many of the old towns formed as valuable urbanised landscapes. However, the transformation of urban structures of viable cities, which also entails transformation of urbanised landscapes, is inevitable. Basically, there are only two ways of transformation – either it happens in its own way or it can be professionally controlled. In this article the problem of urbanised landscape transformation is illustrated by the analytical work carried out for the eastern part of the Old Town of Vilnius (UNESCO heritage site). In the eastern part of the Old Town of Vilnius there are two architectural ensembles that form the characteristic panoramas and silhouettes of the Old Town. In this part of the city, various new built-up initiatives have been active since 2007. The article discusses the urban research, the purpose of which was to answer the question about the potential height of the newly designed built up in a former historic suburb of Vilnius. The potential impact of new buildings on the panoramas, silhouettes, dominant elements, and perspectives as well as nominal spaces of that concrete street of the historical suburb is assessed based on the analysis of the towns cape seen from typical external and internal viewing points of the Old Town. The article describes an integrated method of assessing visual effect on the urbanised landscape.

Introduction. The existing diversity of plant raw materials and products predetermine the prospects of studying their potential as sources of pectin substances. However all current classifications are either fragmented or inconsistent. Study objects and methods. Our theoretical ivestigation aimed to develop an adequate classification for all taxa of plant origin, as well as their tissues and derivatives as pectin-containing materials. We developed criteria for assessing transformation potential of the protopectin complex based on the mass fractions of biologically active non-uronide components, native water-soluble pectin, the protopectin complex, and pectin substances. Individual boundary conditions were based on individual pectin potential, protopectin fragmentation potential, and pectin isolation potential. Results and discussion. Based on the boundary conditions, we defined an universal criterion space that included a set of points M in the coordinates expressed by three main criteria. According to individual boundary conditions, the criterion space was divided, or zoned, into four domains corresponding to protopectin fragmentation potential. They were characterized by: 1) lack of pectin potential, 2) ineffective protopectin fragmentation, 3) ineffective isolation of fragmentation products, and 4) effective isolation. Finally, we developed a generalized algorithm to determine the location of points M[μ1, μ2 , μ3 ] in the zoned criterion space, characterizing the plant tissue. Conclusion. Our approach can be used to assess any plant tissue for its protopectin transformation potential, which determines the technological influence on its pectin potential. This approach is universal, i.e., applicable to both plant tissue and its derivatives.

Disruptive technologies such as IoT, big data analytics, blockchain, and AI have changed the ways businesses operate, with AI holding immense marketing transformation potential. AI is influencing marketing strategies, business models, sales processes, customer service options, and customer behaviors. AI-CRM's improving ability to predict customer lifetime value will generate an inevitable rise in implementing adapted treatment of customers, leading to greater customer prioritization and service discrimination in markets. CSPs are working through the challenging process of digital transformation, driven by the need to compete with fast-moving OTT and consumer tech players. CSPs need to move quickly and can advance digital transformation with solutions that leverage AI which can drive value across the business from network optimization and data analytics through to customer care and marketing engagement. The chapter tries to identify how AI is impacting the CRM in the telecom industry and leveraging the benefits of this technology for better customer management and growth.

AbstractWe present the case of the transformation of an enchondroma in the middle phalanx of the fourth finger of the left hand into a chondrosarcoma. The patient presented a lesion with clinical history, examination, and radiology findings consistent with an enchondroma, which was conservatively treated. Two years later, the patient came for a medical visit with a clinical and radiological variation of the lesion. Computed tomography scans and biopsy revealed a lesion with sarcomatous degeneration which was confirmed after the controlled amputation of the fourth finger. The malignant transformation potential of an enchondroma must be considered.
