This article presents the information on the valorization of waste generated during the production of tissue paper. The possibility of bioconversion of the polysaccharide part of paper sludge into simple sugars has been evaluated. The options for processing the paper sludge before enzymic hydrolysis to achieve the maximum yield of monosaccharides have been considered. Pretreatment with acids has been found to be a key step before the biocatalytic cleavage of waste polysaccharides. An additional yield of enzymic hydrolysis products after pretreatment with acids has been obtained by pre-extraction of the paper sludge with spirit or acetone. It has been established that the most intense enzymic hydrolysis of readily available fractions of the paper sludge takes place in the first 10–12 hours. Further, the process slows down, probably due to the action of the remaining components of the fillers, as well as an increase in the proportion of the difficult-to-hydrolyze polysaccharide part. In all cases, the proportion of absolutely dry non-hydrolyzed residue has been about 43±2 % of the dry matter of the paper sludge. The main products of enzymic hydrolysis have been glucose and xylose. The resulting sugars have been used for mixotrophic cultivation of the Tetradesmus obliquus and Chlorella vulgaris algae. Yeast strains have been selected for the conversion of monosaccharides from the paper sludge. In a series of experiments on non-sterile yeast cultivation, the Candida utilis PAL D and Debaryomyces hansenii SWING R cultures have turned out to be the most productive (within 2.10±0.14 g of air-dry yeast weight/dm3 per 24 hours). The degree of conversion of hydrolysate sugars has been 70±2 %. Most of the remaining sugars (about 80 %) have been represented by xylose. Complete utilization of the sugars has taken place on the 2nd day when having added an extra nitrogen source to the medium. On the other hand, the spent nutrient medium after yeast separation has been suitable for mixotrophic cultivation of microalgae. It has been revealed that the economic costs of pre-treatment of the paper sludge with nitric acid can be leveled by using the resulting salts as a nitrogen source for cultivating yeast. In doing so, the yield of yeast biomass increases by almost 2 times.

At the Second All-Russian Congress on Psychoneurology in Petrograd (January 1924), Vygotsky delivered three papers. The first paper (“Methodology of Reflexological and Psychological Research”), was printed separately, but the text of the other two reports (“How Psychology Should Be Taught Now” and “Results of a Questionnaire on the Moods of Students of the Graduating Classes of the Gomel Schools in 1923”) has not survived. A brief account of these two reports, which appeared in the magazine Krasnaya Nov’ in 1924, is reprinted here for the first time. The author was the revolutionary M.I. Ginzburg (1877-1940), a researcher at the Moscow Psychological Institute in the mid-1920s. He wrote under the pseudonym G. Dayan. Ginzburg-Dayan was severely criticised in 1935 on charges of Trotskyism.

The paper presents detailed biostratigraphical division and lithological characteristics of the Turonian-Lower Santonian interval within the compiled Chukhonastovka section. The presence of the Lower Turonian deposits has been ascertained alongside with the unusual structure of the rock interval synchronous to the Lower Santonian “sponge” horizon.

The widespread use of risograph printing in printing houses requires an increase in the speed of equipment while maintaining the printing quality of the original layouts. The problem of risograph printing is not always obtaining high-quality images, since the risographs used in the standard driver (periodic, non-periodic) do not always allow you to get the printed image the same as in the original. This is reflected in the insufficiency of parameters such as image clarity and sharpness. Problems of poor quality of risograph printing can be solved by changing the settings of the risograph driver for the original layout with additional use of digital filtering and image rasterization. This will require the creation of additional image rasterization methods to improve the initial indicators of the original layout in contrast, clarity, and the correctness of the transmission of halftone images and will improve the quality of printed images, as well as ensure the efficiency of the printing process for a wide range of original layouts.

A representative complex of the Turonian-Santonian carbonate-producing invertebrates has been revealed. It comprised benthic foraminifers, diverse echinoderms, brachiopods, calcareous and siliceous sponges.

Relevance. At present, the problem of soil pollution with heavy metals, which are accumulated in the body of animals and plants, causing various toxic effects, is especially acute. Despite the existence of various methods of reclamation of disturbed lands, as a rule, their application is inefficient or expensive, especially when it comes to abnormally high concentrations of heavy metals. Thus, an extremely urgent task is to find effective and inexpensive ways to recultivate lands contaminated with high concentrations of heavy metals. The article considers one of the promising areas for the reclamation of such lands using a mixture obtained from the accumulated waste of lignin-containing sediments from the pulp and paper industry of Baikal Pulp and Paper Mill as sorbents. Aim. To study and evaluate the effectiveness of using a mixture, which includes frozen lignin-containing sediments of Baikal Pulp and Paper Mill, as heavy metal sorbent. Methods. To assess the sorption efficiency of the obtained sorbent from the frozen sediments of sludge-lignin, the samples of anomalously contaminated soils were taken from the industrial site of the former battery plant "Vostsibelement", located in Svirsk, Irkutsk region. To determine the surface structure of the obtained sorbent for the presence of micro-, meso-, and macropores, its surface was surveyed using a JEOL two-beam system. IR spectroscopy was used to establish the types of bonds between the sorbent and the extracted metals. Results. The studies have shown that the resulting sorbent from the frozen lignin-containing sediments of Baikal Pulp and Paper Mill has a porous structure with a predominance of mesopores, sorbing heavy metal ions, while a large number of micropores contributes to the occurrence of chemical sorption. The obtained IR spectra indicate the possibility of chemical sorption of lead as a result of the reaction of substitution of a hydrogen atom in various hydroxyl groups of the sorbent of the group of aromatic or carboxyl structures. At the same time, the resulting sorbent in terms of its sorption properties is not inferior to commercial natural sorbents – bentonite clay and grassroots peat. The conducted studies allow us to make a positive conclusion about the possibility of using the developed mixture as a sorbent for the immobilization of heavy metals during the reclamation of lands that are contaminated with high levels of heavy metals, including lead.

This article explores the bureaucratic, legal and economic dimensions of the neonatal care. Drawing analytically on the neo-Weberian approach in the sociology of professions [Freidson 2001] and the anthropology of bureaucracy in medicine [Berg 1996; Berg & Bowker 1997], we propose to analyse the medical documents and the practices of its composition as both a constitutive element of medical practice and as organisational infrastructure that ensures the coordination of different professional groups and their interactions with patients. Specifically, we define this part of the work of doctors, nursing staff and health care managers in the context of neonatal resuscitation care as a process of creating and modifying a 'paper body' for their patients, i.e. all the document flow that accompanies the processes of treating and routing the patient. Empirically, the study relies on qualitative data collected within ‘the Birth of the Patient’ project: diaries of included observations of a neonatal intensive care physician, ethnographic observations by social researchers, focus groups with neonatal intensive care unit staff and interviews with medical professionals and healthcare managers. As a result of this data analysis, we find that the documentary history of the newborn patient is shaped by multiple negotiations between different medical professionals and representatives of different health care institutions. In some cases, the patient's 'paper body' turns out to be a major determinant of his or her future trajectory of (de)hospitalisation. We also find that the formation of such a documentary biography of a newborn patient does not directly correlate with his or her clinical condition, but reflects the complex system of distribution of material and non-material resources that constitute the newborn care service and in some cases goes beyond it.

Introduction. Utilization of chemical cellulose fillers in construction industry is one of the ways of processing unused wastes from pulp and paper industry. Decorative, finishing, and heat insulation materials are widely used as construction materials. This paper proposes various compositions and insulation materials characterized by compressive strength of not less than 10 MPa, water tightness of 0.8, and density of not over 600 kg/m3. The likely curing mechanism is studied for cement systems. The possible mechanism of hardening structures formation in the systems is discussed. Methodology. Corrugated fibreboard МS-5B waste is used as a filler, high-early strength cement М-500 (CEM 47.5) – as inorganic binder, and elemental sulfur, polyethylene terephthalate, cementmodified polyurethane (PU) with the addition of nanosized silicon oxide are used as a polymeric matrix. Infrared spectroscopy, terahertz time-domain spectroscopy (THz-TDS), and scanning electron microscopy are used for investigations. Cement samples undergo compressive strength, water tightness and water absorption testing. Results and discussion. Physical and mechanical properties obtained for composites with the paper filler and polymeric matrix based on cement-modified PU, are described, and testing results are compared with the experimental data obtained for materials based on other binders. It is found that the paper filler–cement-modified PU composition is consistent with the purposes of this research. The understanding is improved for the curing mechanism of the polymeric matrix–paper filler system. The THz-TDS data demonstrate a correlation between the spectral transmission and thermal conductivity and density of synthesized heat insulation materials. Conclusion. Synthesized is the effective heat insulation material with relatively high compressive strength, low density, and high tightness to water. Scientific understanding of the curing mechanism is improved.

High lipoprotein(a) (LP(a)) level contributes as an independent risk factor to the development of cardiovascular diseases of atherosclerotic origin. The article contains data on the structural features of this particle, the genetic determination of its metabolism and content in blood plasma, and the pathogenic mechanisms of its proatherogenic, proinflammatory and prothrombotic effects. The authors analyzed epidemiological data on the frequency of elevated LP(a) levels in different population groups and its association with the risk of cardiovascular diseases. The data presented concern the indicators of LP(a) as a risk factor for the development of ischemic stroke (including recurrent stroke) and its individual pathogenetic subtypes, as well as the relationship between LP(a) levels and functional outcomes after cerebral accidents. Current recommendations for the treatment of patients with elevated LP(a) levels in the context of primary and secondary prevention of cardiovascular diseases are analyzed.

Introduction and purpose A pilonidal cyst also known as a pilondial sinus, is an inflammatory condition that occurs in the intergluteal region, which can lead to serious infections. It most commonly affects young men, with risk factors including the presence of hair in this area, excessive sweating, obesity, and poor hygiene. Symptoms include a lump, pain, and purulent discharge from openings in the skin. Diagnosis involves taking a medical history, a physical examination, and often an ultrasound. The aim of this paper is to present and compare the available methods for treating pilonidal cysts. Materials and methods Literature available in PubMed databases were reviewed using the following keywords: ‘’Pilonidal cyst’’, ‘’Hair cyst’’, ‘’Abscess’’, ‘’Treatment of pilonidal cyst’’,’’ Bascom II method’’,’’ Limberg flap’’,’’ Suchorski technique’’, ‘’V-Y or Z skin flap reconstruction’’,’’ the Karadakis’’ Results The available treatment methods can be divided into conservative and invasive approaches. Conservative methods include hair removal and improved hygiene. Among the surgical methods, there are traditional excision techniques and modern methods such as excision using the Bascom II method, Limberg flap, Suchorski technique, or V-Y or Z skin flap reconstruction. The Karadakis method, which involves shifting a skin flap, is particularly effective for obese patients. Conclusion Treatment of pilonidal cysts depends on the stage and symptoms. Abscesses require urgent surgical intervention, while asymptomatic cysts can be treated conservatively or surgically.

The article introduces attraction marketing methods employed by Russian monthly popular science magazine Diletant. The authors compared the printed version and the website. The paper magazine attracts the reader mainly by the topic name printed on its cover as a unique creolized text. The further semantics of the front media text includes various aspects of the main topic. Color highlights both topical issue and regular features. The comparative analysis with the online version revealed some significant differences. The website has a muted color scheme and minimal animation; it contains neither video nor audio materials. Like in the printed version, the function of attraction belongs mainly to illustrations and subtitles. Online Diletant is interactive in navigation, tests, and surveys, which are, however, the only form of interactivity: the site does not provide comments, forums, “likes”, etc. Such limited use of attention-seeking tools makes the digital version of Diletant uncompetitive and inferior to its paper issue.

The recycling of wood processing waste generated at pulp and paper and woodworking enterprises by reusing it in obtaining a high-yield semi-finished product for the production of paper and cardboard has been studied. The economic and environmental feasibility of wood waste recovery is beyond doubt. The aim has been to develop technology and modes for recycling wood waste from the production of high-yield pulp (birch sawdust) and woodworking (coniferous and the mix of coniferous and deciduous chips). In the course of the study, high-yield pulp has been obtained from birch sawdust using continuous technology (at Perm Pulp and Paper Company) and batch technology (at most pulp and paper industry enterprises). Cooking of wood chips has been carried out only using batch technology. It is shown that the recycling of birch sawdust to produce a fibrous semi-finished product for use in the production of paper and cardboard solves an important economic problem of the pulp and paper industry, which is the need to reduce the consumption of pulpwood and preserve forest resources. The process of recycling wood waste does not require changes to current technology. This produces high-yield pulp, which in terms of quality is not inferior to a similar semi-finished product made from birch technological chips and meets the enterprise standards. It has been revealed that wood chips from coniferous and deciduous wood from woodworking enterprises can also be used as a raw material for the production of high-yield pulp, but only together with sawdust from birch wood. High-yield pulp from the chips of coniferous and the mix of coniferous and deciduous wood is obtained with increased yield, but with low mechanical strength, since the neutral-sulfite method is intended for the production of a fibrous semi-finished product only from deciduous wood; coniferous wood is not boiled using this method. High-yield pulp with quality indicators corresponding to the enterprise standards from technological chips is produced by the ratios of chips and sawdust of 50:50 and 70:30. The yield of the semi-finished product from the raw materials of all used compositions is high – 75…82 %. Tests of high-yield pulp obtained from birch sawdust have shown that the fibrous semi-finished product can replace 20 % of the MS-5B waste paper mass in production in the production of paper and cardboard compositions.

The paper considers the question that has gained relevance in the last decade: whether the cryptocurrency bitcoin is money. The economic literature provides different opinions on this issue. The analysis shows that disagreements arise because of the different understanding of the category of ‘money’ rather than because of the nature of bitcoin. The author analyzes popular interpretations of money in terms of their applicability to the definition of the role and place of cryptocurrencies in the financial system. The purpose of this study is to define money as a financial instrument that linksthe creation of gross social product with its distribution. The author believes that money emerged and exists as a tool that ensures a connection between the contribution of each economic entity to the total product of society and the right to receive an equivalent amount of goods from this gross product. At the same time, the author defines money as an ‘ideal right’ to receive a share of the gross social product. In this regard, the analysis of bitcoin shows that this cryptocurrency allows obtaining goods from the gross social product in many countries, while bitcoin owners do not contribute to the gross social product. Based on this, bitcoin cannot be considered money; it is a money substitute, or surrogate money. At the same time, bitcoin was created as money and performs the functions of money, but to a limited extent. Bitcoin can only perform the functions of money as a supplement to an existing official currency. It is not capable of functioning as the only currency in a society. The interpretation proposed in this paper can be used for the purposes of developing the Russian law on cryptocurrencies is currently being worked on by the Government and the Central Bank of Russia.
