Propagation of waves in an incompressible rotating transversely isotropic nonlocal elastic solid
Authors: Singh Baljeet 
Published: July 2021

In this paper, the nonlocal elasticity theory is applied to study the propagation of plane wave and Rayleigh-type surface wave in an incompressible, rotating and transversely isotropic material. The governing equations of motion for an incompressible, rotating, transversely isotropic and nonlocal elastic medium are specialized for a plane. The medium is assumed rotating about an axis perpendicular to the plane. The transverse isotropy axis is taken perpendicular to the surface. The specialized governing equations are first applied to derive a velocity equation for homogeneous plane wave. The specialized governing equations along with traction free boundary conditions are also applied to derive the secular equation governing the wave speed of Rayleigh wave. The speeds of plane wave and Rayleigh wave are computed and illustrated graphically to observe the effects of nonlocality, rotation, anisotropy, frequency and propagation direction. It is noticed from the theory and numerical results that the speeds of both plane wave and Rayleigh wave decrease sharply with an increase in nonlocal parameter or rotation parameter. The speeds of plane wave and Rayleigh wave increase logarithmically with anisotropy material parameter. The feasible ranges of nonlocality, rotation or anisotropy parameters for the existence of plane wave or Rayleigh surface wave are determined for a given wave speed when the values of other parameters are fixed.

Published: July 2021

Purpose. This paper presents the innovative scientifically-based method on efficiency evaluation of the building production management for contracting companies. Otimisation models are substantially aimed at reducing the influence of negative factors and increasing the quality indexes of the organisational process of construction production. Methodology. Methodological approaches of the organisational processes optimisation of construction production are based on the establishment of a well-defined interconnection between the units of the functional structure, the definition of strategies hierarchy of the contracting company.The correlation of duration t and cost c in building production, its influence on the economic appropriateness for projects realisation in civil engineering are analyzed. Findings. Using mathematical analysing methods for cumulative distribution function S(t,c) of two-dimensional random value of construction duration and cost, the basic principles are shown that allow to qualitatively and quantitatively determine the level of influence of the construction market external factors on the implementation of organisational processes in the construction industry, in which a large number of forming elements are involved. The implementation of this methodology permits to assess the real state of organisational processes system in building production, its stability, the degree of determinate indicators structuring in a single functional system, to generate an economic justification in complex. On basis of simulation modeling, efficiency of organisational processes system in building production S(t,c) was determined and graphically illustrated. Originality. The results of the present study demonstrate that it amounted to 58.08 % within the established limits of acceptable risk (LAR) between 0.35 and 0.65. Practical value. It has been shown an implementation practicability of using this methodology by contracting companies at decision-making stage for construction projects initiation with determinate indicators of duration Td and cost Cd. The creation of theoretical and methodological foundations for the development of structural efficiency evaluation algorithms for the organisation of construction production will allow to achieve for contractor companies the highest level of competitiveness in the market of construction services.
Integration of complete elemental mass-balanced stoichiometry and aqueous-phase chemistry for bioprocess modelling of liquid and solid waste treatment systems – Part 1: The physico-chemical framework
Authors: CJ Brouckaert  , BM Brouckaert  , GA Ekama  
Published: July 2021

Bioprocesses interact with the aqueous environment in which they take place. Currently integrated bioprocess and three-phase (aqueous–gas–solid) multiple strong and weak acid/base system models are being developed for a range of wastewater treatment applications, including anaerobic digestion, biological sulphate reduction, autotrophic denitrification, biological desulphurization and plant-wide wastewater treatment systems. In order to model, measure and control such integrated systems, a thorough understanding of the interaction between the bioprocesses and aqueous-phase multiple strong and weak acid/bases is required. This first in a series of five papers sets out a conceptual framework and methodology for deriving bioprocess stoichiometric equations. It also introduces the relationship between alkalinity changes in bioprocesses and the underlying reaction stoichiometry, which is a key theme of the series. The second paper develops the stoichiometric equations for the main biological transformations that are important in wastewater treatment. The link between the modelling and measurement frameworks, which uses summary measures such as chemical oxygen demand (COD) and alkalinity, is described in the third and fourth papers. The fifth paper describes an equilibrium aquatic speciation algorithm which can be combined with bioprocess stoichiometry to provide integrated models of wastewater treatment processes.
Support of State and Private Institutions for Biomedical Start-ups in Russia
Authors: Guseva Olga 
Published: July 2021

This paper describes the differences between biomedical start-ups with state support and start-ups with support provided by private market participants in Russia as a country with limited private investments. Based on the sample of Skolkovo biomedical start-ups, we analyse ownership and management characteristics of start-ups as well as the performance of companies supported by these two types of institutions.
To compare start-ups supported from different sources, the sample of biomedical companies is divided into four clusters based on the presence of state and/or private support. The results of cluster characterization indicate that start-ups with different types of support vary significantly in ownership concentration, share of managerial ownership, gender diversity and CEO experience.Although tests for differences among the groups’ mean values showed the insignificance of performance variation among clusters, start-ups with private funding in the sample were mostly smaller-sized companies with fewer patentsand employees. At the same time, start-ups that were supported from both private and state sources performed better on average in the number of employees and patents and the presence of revenue. Although the causal relationship between the type of support and start-up performance is not investigated in this paper, our results suggest the importance of the synergy of state and private support for biomedical start-up performance in Russia.
Besides contributing to the literature on start-up support in emerging markets, this paper is, as far as we know, one of the first academic studies to provide insights into the market of Russian biotech start-ups.

Authors: Padmaja Nesegopu , Rao Venkateswara 
Published: July 2021

Chronic respiratory diseases account for 4 million deaths annually, and it is one of the most common health issues globally. The present study aims to determine bacterial isolates and their sensitivity pattern as the emergence of antibiotic resistance in the frequently isolated pathogens has complicated the use of empiric therapy with traditional agents. BAL fluid samples of patients with respiratory infections undergoing bronchoscopy in KIMS Hospital, Amalapuram, were collected under aseptic conditions and processed according to standard protocol over 15 months, from July 2018 to October 2019. The antimicrobial susceptibility was tested by the Kirby-Bauer disc diffusion method as per CLSI guidelines. Out of 135 samples, 52(58%) were positive for growth. Of these, 49 were bacterial isolates, and 3 were fungal isolates. The highest isolation rate was observed in the 51-60 yrs age group followed by 61-70 yrs. The common organisms isolated were GNB, predominant being Klebsiella pneumoniae 30(61%), followed by Pseudomonas 15(30%) and E.coli 4(8%). Resistance to allcephalosporins and sensitivity to amikacin followed by piperacillin-tazobactam and other aminoglycosides were noted.BAL has improved sensitivity and specificity in the diagnosis of respiratory infections. An updated antibiogram and monitoring of bacterial isolates and other susceptibility is attributed to antibiotic resistance and the changing pattern of bacterial pathogens.

Nadanie aptece szczególnego statusu prawnego poprzez uznanie jej za placówkę ochrony zdrowia publicznego, w której osoby uprawnione świadczą usługi farmaceutyczne, a także za miejsce sprawowania opieki farmaceutycznej oraz wykonywania zadań zawodowych przez farmaceutów, sytuuje to przedsiębiorstwo w sferze istotnego oddziaływania państwa i jego organów. Nakazuje również stosowanie odmiennych kryteriów oceny działalności tej kategorii przedsiębiorców, a nie jedynie ograniczanie się do kryterium zysku. Zmiana, jaka dokonała się w związku z wejściem w życie ustawy o zawodzie farmaceuty, odnosząca się do zakresu usług i świadczeń zdrowotnych udzielanych przez apteki ogólnodostępne, wzmocniła rolę i zadania apteki jako placówki ochrony zdrowia publicznego, wypełniając lukę w systemie ochrony zdrowia i odpowiadając na jego potrzeby związane z deficytami personelu medycznego oraz przeciążeniem systemu ochrony zdrowia. Tym samym uzasadnione jest pytanie o to, czy bezpieczeństwo pacjenta w tym obszarze zostało zapewnione na odpowiednim poziomie.
Certain Aspects of Arrest of Property in Light of the Case Law of the Appeal Chamber of the High Anti-Corruption Court
Authors: Bykov Denys 
Published: July 2021

The article explores the problems of a temporary seizure and arrest of property in the course of pre-trial investigation in light of the case law of the Appellate Chamber of the High Anti-Corruption Court and the European Court of Human Rights. It is outlined that investigators face particular problems with differentiation of material objects that are subject to seizure upon the decision of an investigator or a prosecutor and may be used for the purposes of the criminal proceedings and those which fall into the category of temporarily seized property, and the legality of their seizure is subject to control by an investigating judge. Investigating judges face the same difficulties which result in decisions on arrest imposed on biological, biometric traces, cigarette butts and other material objects that are not subject to arrest for they do not belong to the category of property. The author analyses whether documents, personal notes, and other items of the kind may be regarded as property and the criteria to categorize them as such. It is concluded that if these items are used as evidence in the criminal proceedings but have no characteristics of property, are not objects of civil rights, have no historical, artistic, scientific, literary, economic, or any other significant value in general or for a certain individual, they are not subject to judicial control and arrest and should be attached to the criminal proceedings in accordance with the rules prescribed by the Criminal Procedural Code of Ukraine.The author pays particular attention to the unfortunate wording of Part 7 of Article 236 of the Criminal Procedural Code of Ukraine, which prescribes that seized objects and documents not included in the list of items to be found in the course of a search, contained in the decision of the investigating judge onpermission to conduct a search, are considered temporarily seized property. This legal norm makes the issue of whether certain items belong to the category of property dependent upon their inclusion in thelist or absence in the list, contained in the decision of the investigating judge. Such an approach contradicts the basic principles of the property law. Therefore, the norm should be excluded from Part 7 of Article 236 of the Code. The author also suggests to change the wording of Part 7 of Article 237 of the Code and to clearly outline that documents, as a general rule, are seized and items that fall into the category of property are temporarily seized.The suggested approach will lead to harmonization of the norms of criminal procedural law with those of civil law, setting clear and understandable criteria for defining the legal status of items seized or temporarily seized in the course of examination or search and fulfilling the tasks of effective and impartial pre-trial investigation.
Collisions Regarding еhe Participation of the Prosecutor in Civil Procedure
Authors: Yarosh Illia 
Published: July 2021

The author of the article describes the collisions regarding the participation of the prosecutor in the civil procedure. It is mentioned that the emergence of collisions regarding the participation of the prosecutor in the civil procedure is associated with the reform and adoption of the new civil procedure legislation, as well as the amendments to the Constitution of Ukraine. The collisions which have arisen between the Constitution of Ukraine and the Law of Ukraine “On the Prosecutor’s Office” of 2014 and the Family Code of Ukraine are described. According to the Constitution of Ukraine, the prosecutor is deprived of the function of representation of citizens, and now has the function of representing the state in the civil procedure. It is mentioned that the legislator erroneously substantiates the existence in the laws of Ukraine, which contradict the constitutional norms, of such functions of the prosecutor as the representation of citizens and protection of children’s rights by the social role of the state. The State ombudsman should perform these functions, and the state should develop the institution of the free legal aid. The author analyzes the scientific publications of the last four years and emphasizes the contradictory points in them. It is mentioned that not all scientists have consistently considered the participation of the prosecutor in the civil procedure. Today not only society but also scientists interpret the laws differently due to the shortcomings of the legislation. It is separately substantiated that the prosecutor is the official representative of the state, defending its interests in court. So the plaintiff in cases, where there is no state body that can file a lawsuit, should be the state but not the prosecutor. It is emphasized that the legislation of Ukraine regarding the participation of the prosecutor in civil proceedings has to be brought in line with the provisions of the Constitution of Ukraine. The prosecutor must perform only the functions specified in the Constitution of Ukraine. In this case, the principles of the rule of law and a democratic social state will be maintained.

Published: July 2021

Background. The study of the growth of lung cancer (LC) has an important clinical significance for morphological verification, the choice of the treatment method, and the determining of prognosis. Investigation of this question allows to clarify the histogenesis of LC. The aim of our study was to compare the results of cytological studies of the material obtained during flexible bronchoscopy (FBS) and scrapings from the operated tumors of the bronchi to clarify the nature of LC growth. Design. To study the growth of tumors in the bronchi in relation to the bronchial mucosa, the cytological examination of the material obtained by FBS and scrapings from the surface of the operated bronchial tumors of 31 patients has been performed. Results. In the preoperative period, in the material of FBS, tumor cells were found only in 1/3 of patients. To obtain the optimal material from exophytic tumors of the bronchus, scrapings were carried out from the entire surface surgical material of the same patients. Cytological preparations of the obtained scrapings confirmed the presence of cancer cells in more than 1/3 of patients. In the rest of the observations, scrapings from the tumor surface contained only cells of the cylindrical epithelium. Conclusions. The cytological investigations made it possible to state that in 2/3 scrapings from surfaces of exophytic tumors of the bronchus contained only cells of the cylindrical epithelium; therefore, the tumors grow under it.

The study of the energy potential of forest bedding in the deciduous forest areas of the “Lisnyky” Nature Reserve of the Holosiivsky National Nature Park revealed the nonlinear nature of its annual dynamics. The main sources of replenishment of the organic stock of this component of broadleaf forest phytocoenosis were the active development of herbaceous vegetation in spring and significant leaf rainfall in autumn. At the same time, significant changes in the processes of accumulation and decomposition of organic matter of forest bedding occurred under the influence of climatic factors such as temperature and precipitation. The experimental site was located in moderately moist oak forest ass. Convallario majali-Quercetum roboris Shevchyk & V. Sl. in Shevchyk & al. 96. The age of the old Quercus robur oak trees, which occupy the first tier of the forest, exceeds 100 years. The second tier is formed by other broadleaf species, Acer platanoides, A. campestre, A. tataricum, Carpinus betulus, Fraxinus excelsior and Tilia cordata, up to 30 years old. The energy reserve was calculated from the dry organic matter content. The obtained data were compared with meteorological data of the corresponding month of the year and correlation coefficients were calculated. Correlation analysis confirmed the relationship between climatic factors and the energy potential of forest bedding. The inverse of the mean force (R = -0.515) shows the relationship between the energy potential of the forest bedding and the average monthly temperature and the high direct correlation between the energy potential and the amount of average monthly precipitation (R = 0.755). In general, forest bedding can be considered an important component of the ecosystem, which responds quickly to external factors and characterizes the state of the forest ecosystem, and its energy potential can be an effective indicator of forest ecosystem stability in climate change monitoring.

Increasing anthropogenic pressure, global climate change, and the lack of large introduction centers in the Chernihiv region makes it important to preserve rare species of flora ex situ outside this administrative region. The article presents the results of the study of taxonomic composition and evaluation of the success of the introduction of rare plant species of Chernihiv region in the M. M. Gryshko National Botanical Garden of National Academy of Sciences of Ukraine. The study of rare plant species and the development of methods for their effective reproduction was initiated in the NBG in 1970 in a separate section “Rare plants of the flora of Ukraine.” It is established that the collection grows and protects 57 phythorarites of Chernihiv region, of which 29 species are listed in the Red Book of Ukraine (III edition), and 28 species – in the “List of regionally rare plant species of Chernihiv region”. Most plants successfully recover ex situ with moderate care or without additional human intervention. The biomorphological spectrum of introduced plants is dominated by cryptophytes (50.88 %) and hemicryptophytes (42.11 %), the shares of phanerophytes, hamephytes and therophytes are insignificant. 17 species of phythorarites formed stable homeostatic populations. Of these: 5 species are listed in the Red Book of Ukraine (Allium ursinum, Crocus reticulatus, Epipactis helleborine, Galanthus nivalis, Pulsatilla pratensis) and 12 species – in the “List of regionally rare plant species of Chernihiv region” (Aster amellus, Corydalis intermedia, C. marschal, Daphne mesereum, Equisetum hyemale, Iris hungarica, Phlomis tuberosa, Primula veris, Pteridium aquilinum, Scilla bifolia, S. sibirica, Vinca minor). Thus, the cultivation of almost a third of the phythorarites of Chernihiv region in the M. M. Gryshko National Botanical Garden testifies to the effectiveness of their preservation ex situ.
