The impact of digitalization on the Intellectual capital formation and use (case of service enterprises)

The article discusses the directions, problems and results of using digital solutions in enterprises in the service sector. It is shown that digitalization in the service sector is due to the emergence of a new type of resource - a large amount of specific information about stakeholders. Digitalization has a direct effect on enterprises in the service sector in the form of the development of the institutional environment and the technical infrastructure of digitalization, as well as an indirect action related to the transformation of the enterprises of this industry themselves, their missions and goals. The areas of digitalization in the service sector are indicated. It is shown that the use of digital technologies affects cost reduction and sales growth, and also has a significant impact on the formation and use of the intellectual capital of service enterprises. The features of the formation of the intellectual capital of the enterprise at the stages of the life cycle are considered. The elements of intellectual capital are clarified, which have received an impetus for development due to digitalization. Possible positive directions of the impact of digitalization on the elements of intellectual capital are presented, and the dynamics of the impact of digitalization decisions on the elements of intellectual capital at the stages of the enterprise life cycle is considered

An assessment of the sewer tunnel stress-strain behavior during the reconstruction of an object of cultural heritage

The article offers an information about the work carried out on technical monitoring of the city sewerage system tunnel in the framework of the actual problem of recreating the objects of cultural heritage of St. Petersburg, which fall into the protected zone of underground engineering networks. The purpose of the study is to identify values of the stress-strain state of the tunnel lining at various stages of construction of a cultural heritage object located on the earth’s surface in the immediate nearness. For formation of a base of the analyzed values was undertaken geolocation of ground massive, conducted geodetic measurements, defined the deformation of the soil by inclinometer boreholes, was obtained graphs of precipitation the soil massive, developed by setup technology for strain gauge sensors linear displacement inside the tunnel, worked out the mathematical model in the specialized software. Analysis of the obtained results allowed us to associate values of the stress-strain state of the collector tunnel effect from the buildings under construction and structures, as well as to identify the actual task for further research to develop methods of rapid diagnosis of the stress-strain state of tunnel lining structures in terms of their special mode of operation

Assessment of in vivo estrogenic and anti-inflammatory activities of the hydro-ethanolic extract and polyphenolic fraction of parsley (Petroselinum sativum Hoffm.)

Ethnopharmacological relevance: Since the dawn of time, medicinal and aromatic plants (AMPs) represent a precious heritage for humanity, especially in developing countries, who exploit their virtues in traditional pharmacopoeia to cope with health problems such as diabetes, kidney stones, ulcer, and digestive disorders. Petroselinum sativum Hoffm. belongs to Apiaceae family. It is traditionally used to treat arterial hypertension, diabetes, cardiac disease, renal disease, and recently reported as a plant endowed with a female anti-infertility effect. Aim of the study: This study aims to evaluate the in vivo effect of hydro-ethanolic extract and polyphenols of Petroselinum sativum Hoffm. on cholesterol, protein and estrogen levels, and characterize the chemical composition of polyphenolic fraction. In addition, acute toxicity and anti-inflammatory activity of tested extract was also investigated. Materials and methods: Chemical composition of polyphenolic fraction was determined using High-Performance Liquid Chromatography with Diode-Array Detection (HPLC-DAD). First, toxicological investigations including sub-acute toxicity were performed by measuring animals' weights daily for four weeks. Afterwards, histopathological examination of livers and kidneys, and serum assay of ASAT and ALAT were also checked. Next, the acute in vivo anti-inflammatory study of the hydro-ethanolic extract and polyphenols of Petroselinum sativum Hoffm. versus Indomethacin was conducted. Furthermore, we evaluated the estrogenic effect of its hydroethanolic extract and the polyphenolic fraction following biochemical assays for the determination of proteins, cholesterol and estrogen levels. Results: The results revealed the presence of some phenolic compounds mainly ferulic acid, gallic acid and quercetin. Petroselinum sativum Hoffm. extracts also showed no evidence of hepatotoxicity nor nephrotoxicity, with remarkable anti-inflammatory activity, as well as a significant estrogenic effect compared to negative control. Conclusion: This study provides a scope of the potential use of Petroselinum sativum Hoffm. extracts in counteracting female infertility issues.Peer reviewe
