Water Hammer Simulation Method in Pressurized Pipeline with a Moving Isolation Device
Authors: Zhang Kang , Zeng Wei , Simpson Angus R. , Zhang Shimin , Wang Chao
Published: June 2021

Smart isolation devices (SIDs) are commonly used in pressurized subsea pipelines that need to be maintained or repaired. The sudden stoppage of the SID may cause large water hammer pressures, which may threaten both the pipeline and the SID. This paper proposes a simulation method by using a coupled dynamic mesh technique to simulate water hammer pressures in the pipeline. Unlike other water hammer simulations, this method is the first to be used in the simulation in pipelines with a moving object. The implicit method is applied to model the moving SID since it has the mutual independence between the space step and the time step. The movement of the SID is achieved by updating the size of the computational meshes close to the SID at each time step. To improve the efficiency of the simulation and the ability of handling complex boundary conditions, the pipe sections far away from the SID can also be simulated by using the explicit Method of Characteristics (MOC). Verifications were conducted using the simulated results from the Computational Fluid Dynamics (CFD) numerical simulation. Two scenarios have been studied and the comparisons between the simulated results by using the dynamic meshes in 1D methods and those by the CFD simulation show a high correlation, thus validating the new method proposed in this paper.
Diversity and Activity of Aquatic Cellulolytic Bacteria Isolated from Sedimentary Water in the Littoral Zone of Tonle Sap Lake, Cambodia
Authors: Chantarasiri Aiya
Published: June 2021

Tonle Sap Lake is the largest freshwater lake in Southeast Asia, and it is regarded as one of the most biodiverse freshwater ecosystems in the world. Studies concerning aquatic cellulolytic bacteria from Tonle Sap Lake remain scarce. Cellulolytic bacteria and their cellulases play a vital role in the biogeochemical cycles of lake environments, and their application in biotechnological industries is likewise an important component of their usage. This study aimed to assess the isolation, genetic identification, bioinformatic analyses, and activity characterization of aquatic cellulolytic bacteria. The cellulolytic bacteria isolated from sedimentary water samples in the littoral zone of the lake belong to the genera Aeromonas, Bacillus, and Exiguobacterium. Several isolated aquatic bacteria were designated as rare cellulolytic microbes. Remarkably, B. mojavensis strain REP303 was initially evidenced by the aquatic cellulolytic bacterium in freshwater lake ecosystems. It was considered a highly active cellulolytic bacterium capable of creating a complete cellulase system involving endoglucanase, exoglucanase, and β-glucosidase. The encoded endoglucanase belongs to the glycosyl hydrolase family 5 (GH5), with a carboxymethylcellulase (CMCase) activity of 3.97 ± 0.05 U/mL. The optimum temperature and pH for CMCase activity were determined to be 50 °C at a pH of 7.0, with a stability range of 25–55 °C at a neutral pH of 7.0–8.0. The CMCase activity was enhanced significantly by Mn2+ and was inhibited considerably by EDTA and ethyl-acetate. In conclusion, this study is the first to report data concerning aquatic cellulolytic bacteria isolated from the littoral zone of Tonle Sap Lake. A novel strain of isolated cellulolytic B. mojavensis could be applied in various cellulose-based industries.

It is a well–known fact that heavy metal pollution in sediments causes serious problems not only in the Danube basin, but also in the large and small adjacent river streams. A suitable method for assessing the level of heavy metals and their toxicity in sediments is the calculation of pollution indices. The present research aims to assess heavy metal pollution in the Lower Danube surface sediments collected along the Danube course (between 180 and 60 km) up to the point where the Danube River flows into the Danube Delta Biosphere Reserve (a United Nations Educational, Scientific and Cultural Organization—UNESCO, protected area). In addition, this monitored area is one of the largest European hydrographic basins. Five heavy metals (Cd, Ni, Zn, Pb, Cu) were analyzed in two different seasons, i.e., the autumn of 2018 and the spring of 2019, using the Inductively Coupled Plasma Mass Spectrometry (ICP– MS) technique. Our assessment of heavy metal pollution revealed two correlated aspects: 1. a determination of the potential risks of heavy metals in sediments by calculating the Potential Ecological Risk Index (RI), and 2. an evaluation of the influence of anthropogenic activities on the level of heavy metal contamination in the surface sediments, using three specific pollution indices, namely, the Geo–Accumulation Index (Igeo), the Contamination Factor (CF), and the Pollution Load Index (PLI). The results of this pioneering research activity in the region highlighted the presence of moderate metal (Ni and Cd) pollution and a low potential ecological risk for the aquatic environment.

Published: June 2021

Quantitatively assessing fecal indicator bacteria in drinking water from limited resource settings (e.g., disasters, remote areas) can inform public health strategies for reducing waterborne illnesses. This study aimed to compare two common approaches for quantifying Escherichia coli (E. coli) density in natural water versus the ColiPlate™ kit approach. For comparing methods, 41 field samples from natural water sources in Kentucky (USA) were collected. E. coli densities were then determined by (1) membrane filtration in conjunction with modified membrane-thermotolerant E. coli (mTEC) agar, (2) Idexx Quanti-Tray® 2000 with the Colilert® substrate, and (3) the Bluewater Biosciences ColiPlate kit. Significant correlations were observed between E. coli density data for all three methods (p < 0.001). Paired t-test results showed no difference in E. coli densities determined by all the methods (p > 0.05). Upon assigning modified mTEC as the reference method for determining the World Health Organization-assigned “very high-risk” levels of fecal contamination (>100 E. coli CFU/100 mL), both ColiPlate and Colilert exhibited excellent discrimination for screening very high-risk levels according to the area under the receiver operating characteristic curve (~89%). These data suggest ColiPlate continues to be an effective monitoring tool for quantifying E. coli density and characterizing fecal contamination risks from water.
Performance Assessment System for Energy Efficiency in Wastewater Systems
Authors: Jorge Catarina , Almeida Maria do Céu , Covas Dídia
Published: June 2021

Performance assessment is essential to effectively evaluate and monitor the activity of water utilities, support decision making, and encourage continuous improvement. Performance assessment systems (PAS), covering several service objectives and criteria, have been successfully applied in water supply and wastewater systems. Tailored approaches focusing on the assessment of the energy use and efficiency in wastewater systems are still limited. This paper aims at the development and demonstration of a comprehensive PAS for energy efficiency, tailored for wastewater systems, incorporating criteria related to energy consumption, operation and maintenance (O&M) costs, and environmental impacts, such as untreated discharges and greenhouse gases emissions, among others. Management and control of excessive or undue inflows to these systems is specifically addressed by several novel criteria and metrics. The proposed PAS should be adapted by each utility to be aligned with the objectives of the organisation and with the implemented asset management strategy. The proposed approach and the resulting consolidated PAS are thoroughly described. Results from the application of the PAS to several Portuguese utilities are discussed. This PAS aims at contributing to a reliable and replicable process to assess energy efficiency in wastewater systems and to encourage a more rational energy management.

Published: June 2021

Two labscale aerobic moving bed biofilm reactor (MBBR) systems, with a different type of biocarrier in each (K3 and Mutag BioChip), were operated in parallel for the treatment of real saline bilge water. During the operation, different stress conditions were applied in order to evaluate the performance of the systems: organic/hydraulic load shock (chemical oxygen demand (COD): 9 g L−1; hydraulic retention time (HRT): 48–72 h) and salinity shock (salinity: 40 ppt). At the same time, the microbiome in the biofilm and suspended biomass was monitored through 16S rRNA gene analysis in order to describe the changes in the microbial community. The dominant classes were Alphaproteobacteria (families Rhodospirillaceae and Rhodobacteraceae) and Bacteroidia (family Lentimicrobiaceae), being recorded at high relative abundance in all MBBRs. The structure of the biofilm was examined and visualized with scanning electron microscopy (SEM) analysis. Both systems exhibited competent performance, reaching up to 86% removal of COD under high organic loading conditions (COD: 9 g L−1). In the system in which K3 biocarriers were used, the attached and suspended biomass demonstrated a similar trend regarding the changes observed in the microbial communities. In the bioreactor filled with K3 biocarriers, higher concentration of biomass was observed. Biofilm developed on Mutag BioChip biocarriers presented lower biodiversity, while the few species identified in the raw wastewater were not dominant in the bioreactors. Through energy-dispersive X-ray (EDX) analysis of the biofilm, the presence of calcium carbonate was discovered, indicating that biomineralization occurred.

Objective. The study deals the influence of different biofeedback (BFB) depth for support reaction on the performance of a short course (3 sessions) for a motor-cognitive training of static and dynamic types in the rehabilitation of patients after a radical mastectomy.
Subjects and methods. 21 patients between the ages of 40 and 74 years after radical mastectomy for breast cancer (BC) were examined and performed rehabilitation with the BFB depth for support reaction with a change normal sensitiveness of the force platform by 15, 30, 45 and 60 %. The 1st group included aged 40–54 patients, and the 2nd group included aged 57–74 patients.
Results and conclusion. It was found that after 3 courses of the motor-cognitive training of dynamic type (“Lights”), conditionally “younger” patients showed an increase of their results from the fi rst to the third session in all four variants of the changing BFB depth (15, 30, 45, 60 %) from the normal sensitiveness of the force platform. These results weren’t found in dynamics in the 2nd group of patients. Data from static training (“Target”) shows that changing of the BFB depth in the range from 15 to 60 % don’t affect the results of exercises in both groups throughout 3 sessions. These types of training for older patients weren’t as effective as for younger patients over such a short period. Probably, these results of dynamic training depend on multitasking and learning difficulties. The obtained results should be taken into account when a training plan will be drowned up because the incorrect selection of the BFB depth and the short period of medical rehabilitation will reduce the eff ect of training.

The results of the treatment of women (n = 94) suffering from genital endometriosis are presented. The first (control, n = 30) group of women received standard drug therapy; the second (main, n = 64) group of women additionally had hirudotherapy procedures using medical leeches. The course of treatment consisted of 10–12 procedures. The state of cerebral circulation was assessed according to the rheoencephalography data before and after the treatment, as well as after 1, 3, 6, and 9 months. As a result, in patients in the 2-nd (main) group receiving complex treatment, the state of cerebral circulation improved signifi cantly. Moreover, according to the statistical regression analysis, it was possible to predict its further decrease by two periods ahead, compared with the treatment results in patients in the 1-st (control) group.
Dynamics of a simplified nonlinear model offering insights into the hammering type brake squeal initiation process
Authors: Sen Osman Taha , Singh Rajendra
Published: June 2021

This article develops a simplified mechanical system model that offers insights into the hammering type brake squeal initiation process while overcoming a void in the literature. The proposed formulation derives a nonlinear two-degree-of-freedom model where a mass is in contact with
a rigid frictional surface that moves with constant velocity. The kinematic nonlinearities arise from an arrangement of springs that support the mass, as well as from contact loss between the mass and frictional surface. First, the nonlinear governing equations are numerically solved for several
normal force vector arrangements, and a wide range of dynamic responses are observed. Results show that some assumptions made in prior articles are not valid. Second, the nonlinear governing equations are linearized, and the existence of quasistatic sliding motion is sought for selected inclined
spring arrangements. Third, the dynamic stability of the linearized system is examined and compared with the results of a nonlinear model. The coupled modes are found even though some contradictions between the model assumptions and linearized system solutions are observed. Finally, the nonlinear
frequency responses are calculated using the multi-term harmonic balance method although only the contact loss nonlinearity is retained. Shifts in the resonant frequencies during the motion of the pad are clearly observed. In conclusion, the contact loss nonlinearity is found to be crucial,
and as such, it must not be ignored for the squeal source investigation. Finally, the new model offers insight into the squeal initiation process while revealing the limitations of linearized system analyses.

The organization of the technological process of manufacturing concrete products with the use of electrothermal treatment with high-frequency currents at both large and small industrial enterprises is considered. This technology is also useful for winter concreting and field concrete work. The technology is based on the use of a centralized high-frequency power supply, made using high-power transistor voltage converters, for simultaneous processing of several products. A pilot plant for the implementation of such a technology and the results of an experiment with its use are presented. The plant capacity was estimated based on the developed work schedule. Using the example of manufacturing foundation blocks of the FBS 12.4.6 type, it is shown that the actual schedule of work on the manufacture of products using electrothermal treatment with high-frequency currents leads to the fact that the power consumed from the supply network has a relatively small value (13.2 kW), which almost any enterprise can afford.

A variant of the crack resistance criterion and the strength criterion of plane-stressed structures made of high-strength fiber-reinforced concrete, fiber-reinforced concrete is proposed. The criteria are based on the theory of plasticity of concrete and reinforced concrete G.A. Genieva. In general, the condition for crack resistance of a plane-stressed fiber-reinforced concrete element is presented in the form of an ellipse with jumps on the coordinate axes of the main reduced stresses. The strength condition of a fiber-reinforced concrete element is described by a complex figure that takes into account cracking in the element under a plane stress state. The characteristic points on the coordinate axes are calculated from the physical and mechanical characteristics of concrete strength, obtained as a result of testing high-strength fiber-reinforced concrete for uniaxial compression and uniaxial tension with “dissolved” fiber in the concrete body and reinforcement reduced to concrete. The results of a comparative analysis of the criteria for crack resistance and strength of high-strength concrete and high-strength fiber-reinforced concrete are given, depending on the percentage of fiber in the concrete body and the type of fiber used. The proposed analytical dependences can be used to analyze the crack resistance and strength of plane-stressed reinforced concrete beams-walls reinforced with fiber, corner zones of shallow shells and other plane-stressed structures made of high-strength fiber-reinforced concrete and fiber-reinforced concrete.

The moments in reinforced concrete during bending with torsion were determined, the new first hypothesis of linear deformations and its filling of the diagram during bending with torsion for the analytical second functional as a function of three functions - an exponent, a straight line and a parabola curve. A simple new method is found (from the family of mesh methods) and a summed function of additional deplanation is proposed. The new second hypothesis of angular deformations and its filling of the diagram in reinforced concrete during bending with torsion is constructed. The analytical first general undefined functional is a function of functions, as well as transitions, operations between functions. At the same time, a spatial triple integral of arguments from longitudinal deformations for the first hypothesis was obtained, as well as the third and fourth functionals (indefinite and definite) from moments (bending and twisting) with the projection of the coefficients of the diagram of "deformations - stresses" of compressed concrete and the filling coefficients of the diagrams of compressed concrete for their shoulders to the neutral axis for a field of small squares. The bending and torque moments from the compressed area of concrete and working reinforcement are determined (folded for their levels or expanded into algebraic functions from the synthesis of the computational model of reinforced concrete blocks). In this case, we have new functionals (from the first to the fourth functional), proposed hypotheses (first and second), as well as cross sections (from small squares) to a spatial crack. There are also jumps (cracks) lateral, normal, etc., from the first - third stage of average deformations of concrete and working reinforcement.

Textile concrete is an innovative composite material that has been the subject of intensive research since the beginning of the 90s of the last century. After the approval of the rules and regulations on its application to strengthen floor slabs, an important step was taken towards its entry into the building materials market. Questions regarding the reinforcement of rod-shaped load-bearing elements of building structures need additional research. Despite the great potential available, the method of tying load-bearing supports and columns is still not well understood. There is a need for research on a wide range of geometric parameters and the reinforcement systems used. The Institute of Reinforced Concrete of the Higher Technical School in Leipzig tested various samples of carbon-reinforced samples in a wide range of geometrical parameters. Their goal was to assess the effect on a possible increase in the bearing capacity of carbon-reinforced columns at a concentrated point load.

White faeces syndrome is one of the major disease problems in shrimp aquaculture, resulting in enormous economic losses to farmers. Although white faeces syndrome is usually associated with Enterocytozoon hepatopenaei (EHP) infections, it may not be the sole cause for the occurrence of white faecal strings on the pond water surface. There is limited information on the microbial dynamics in a pond affected by white faeces syndrome. Hence, this study aimed at the bacterial community changes occurring on the surface of shrimp Penaeus vannamei Boone, 1931 afflicted by the white faeces syndrome and the pond water in which it was reared. The pond water and the shrimp surface shared >45 % of the operational taxonomic units (OTUs), reflecting the influence of water quality on the bacterial community composition on the shrimp surface. Among these, the Proteobacteria formed the principal phyla and remained unaltered throughout the culture period. Bacteroidetes formed the second largest group across samples, followed by Cyanobacteria, Actinobacteria, Planctomycetes, Verrucomicrobia and Chloroflexi. The relative abundance levels of health indicator bacterial families such as Thiotrichaceae,Microbacteriaceae and Chitinophagaceae showed significant fluctuations on the shrimp surface. Disease indicators such as Rickettsiaceae, Mycobacteriaceae showed an increase in numbers on the shrimp surface. PICRUSt functional predictions revealed higher abundances of genes involved in metabolism and genetic information processing. The study provides valuable findings on the bacterial communities of rearing water and shrimp surface associated with white faeces syndrome.

The authors consider features of the triple structure of Ag-Cu-S solid solution decomposition resulted from redistribution of matter in the ores of the epithermal Au-Ag Teploye deposit due to the spatial combination of volcanogenic Au-Ag mineralization, with relatively later copper porphyry. The discovery of the mckinstryite, copper-silver sulfide, permits to consider the occurrence of copper in acanthite a non-structural impurity element, while the term "cupreous acanthite" appears insufficiently substantiated. It has been suggested that the mckinstryite-jalpaite (+ acanthite) structure was formed not by the decomposition of a solid solution or the crystallization of a normal hydrothermal solution, but but in the course of solidification of the sluggish, viscous, colloid-like substance in a metastable environment under low-temperature conditions, and was accompanied by structural rearrangement of its mineral constituents.

Catching of Lesser Sandhill Cranes of the Eurasian population was carried out to study the features of their migration using GPS-GSM transmitters. During 2018-2019 we caught 11 adult flying cranes using self-tightening leg loops in the Chaun Lowland, Chukotka, Eastern Siberia. The method has been proven to be the most effective and non-traumatic for catching cranes during summer. Setting of loops along the edge of feeding habitat, the lake with abundant invertebrates primarily crustaceans Conchostraca, was found to be the most effective method of capturing. The construction is cheap and easy to use, install and transport.

YYoğun kentleşme hareketleri, aşırı tüketim, enerji kaynaklarının bilinçsiz kullanımı, çeşitli sebeplerle insanların büyük kentlere göç etmesi ve hızlı nüfus artışı günümüz kentlerinin ortak sorunlarıdır. Kentlerle ilgili sorunların farkına varan bazı yerel yönetimler 1999 yılında İtalya’da Yavaş Kent Hareketi (Cittaslow Movement) adında bir kentsel hareket başlatmışlardır. Yavaş Kent Hareketi’nin temel hedefi, mekanların gelişimini iyi yemek, sağlıklı çevreler, sürdürülebilir ekonomi ve toplumsal yaşamın geleneksel ritüelleri esas alınarak beslemektir. Yavaş Kent olmaya aday kentler; yerel sanat ve zanaatleri teşvik etmenin yanı sıra ürünleri bölgeyi tanımlı kılan, bölgeye kimlik ve imaj kazandıran modern endüstrinin desteklenmesini de sağlamak üzere faaliyet gösterirler. Ayrıca, yapılı çevrenin karakterinin korunması, ağaç dikimi; yeşil alanların, bisiklet yollarının ve yayalaştırılmış bölgelerin arttırılması, meydanların reklam panoları ve neonlardan arındırılmış olması, araba alarmlarının yasaklanması, gürültü kirliliğinin, ışık kirliliğinin ve hava kirliliğinin azaltılması, alternatif enerji kullanımının desteklenmesi, toplu taşımanın ve yeni düzenlemeler içinde ekoloji dostu mimarinin geliştirilmesi de Yavaş Kent’lerin zorunlu uygulamalarından bazılarıdır.Bilecik ili Ankara, İstanbul, Eskişehir, Bursa gibi büyük kentlere yakın olmasıyla coğrafi olarak, çeşitli uygarlıklara ev sahipliği yapması ve Osmanlı Devleti’nin kuruluşunda merkez görevi görmesi ve Kurtuluş Savaşı’nda verdiği mücadelelerle tarihi olarak önemli bir konumdadır. Çalışma ile Osmaneli kentinin Yavaş Kent Hareketi’ne katılmaya uygunluk durumunun incelenmesi, Yavaş Kent Hareketi’ne katılmanın Osmaneli kent imajını geliştirmeye yönelik yapacağı olumlu fiziksel etkilerin saptanması ve tasarıma yönelik önerilerin geliştirilmesi hedeflenmiştir.

This study was carried out to determine the strength of long span stone bridges and stress areas of a historical bridge by using finite element method during earthquakes, floods, and vehicle traffic. The possible earthquake impact of the region and the behavior of the bridge under the effect of the 2011 Van earthquake were investigated. The stresses that will be caused by hydrostatic and vehicle loading applied to the bridge are dwelled on. This study aimed to shed light on future restoration work. As a result of the vehicle, hydrostatic load and dead load analysis, the biggest deformation occurred in the arch K9, which has the largest arch span. According to the results of the earthquake analysis, maximum deformation occurred in the K10 arch, which is one of the arches with the largest arch span of the bridge. In addition, inearthquakes affected in the X and Z direction, it was observed that the arches and piers in the middle of the bridge, that is, these relatively higher structural elements were subjected to more stress. It has been determined that the A11 pier of the bridge is the structural element exposed to the most pressure.

Pineapple fruit is included in the type of tropical fruit, which is quite popular because it contains a lot of Vitamin C, which is quite high. Pineapple is a local fruit in the Kampar area, this fruit can be consumed directly and become other local processed products. Therefore, the quality of pineapple ripeness must be maintained. The problem that occurs at this time is that the pineapple fruit selection process is still done manually, by looking at it visually, so mistakes can occur in the process of clarifying pineapple fruit identification according to standards. Therefore, it is necessary to research the ripeness of pineapples using the Color Space Algorithm Hue Saturation Intensity (HIS). The variables to be input are based on photos of ripe, half ripe, and raw pineapples using a smartphone camera or DSLR camera with a minimum resolution of 8 MP. Clarifying the results with image processing and Hue Saturation Intensity (HIS) transformation has an accuracy rate of 80% for the 20 image test data. So that the expected results can help pineapple farmers in detecting the level of maturity of pineapple fruit, which is difficult, can minimize errors in determining the ripeness of pineapple fruit

Chitosan is a natural polymer, which presents, according to studies made up to present, low toxicity and goodbiocompatibility. Recent studies are focused not only on its antimicrobial effects on textiles, because this polysaccharideleads to improvements such as: shrink resistance, dye uptake etc. Two Romanian traditional shirts were non-invasively tested by applying Chitosan and by investigating the SEM images,before and after applying the chitosan. The paper underlines the surface modifications of tested textiles using chitosan.The odd agents on the fibres surfaces were removed and the limitation of the number of microorganisms was observed
Matoniaceous ferns from the Lower Jurassic strata of the Holy Cross Mountains (SE Poland). Revision of historical specimens and description of some new materials
Authors: Pacyna Grzegorz
Published: June 2021

Ferns from the family Matoniaceae are characteristic but not very numerous elements of Early Jurassic floras of the Holy Cross Mountains. Based on historical specimens from the Geological Institute of the Polish Academy of Sciences, only partly published by Raciborski and Makarewiczówna, and a new collection gathered recently from the Gromadzice outcrop, two taxa are here recognised: Matonia braunii and Phlebopteris angustiloba, of which only P. angustiloba is rather frequent. Both species are represented by sterile and fertile specimens well comparable with historical and recently published material of these species from Greenland, Germany and Sweden. Specimens referred by Raciborski to Laccopteris elegans (illegitimate name) do not belong to Matoniaceae.

Authors: Almeida Fernando
Published: June 2021

Entrepreneurship education aims to contribute to the emergence of innovative skills, abilities, and competencies in people, in the most diverse sectors and branches of activity of contemporary society, regardless of the intention to establish a new start-up. This study explores the development of entrepreneurial competencies, intentions and attitudes offered by a higher education institution through the adoption of the eValueComp assessment tool. It offers significant contributions to the business education field particularly aimed at higher education professors who intend to place the student in a more active position and provide an entrepreneurial education, which will be useful for their future professional career. The findings revealed a significant increase of entrepreneurial competencies, general entrepreneurial attitudes, and perception of entrepreneurial feasibility. However, entrepreneurial intentions have evolved only marginally. Furthermore, the age and number of years of professional experience are two correlated factors that contribute to students having a greater perception of the risks associated with the entrepreneurship process.

The problem of normal oscillations of a viscous stratified fluid with an elastic membrane
Authors: Tsvetkov D.O.
Published: June 2021

Normal oscillations of a viscous stratified fluid partially filling an arbitrary vessel and bounded above by an elastic horizontal membrane are studied. In this case, we consider a scalar model problem that reflects the main features of the vector spatial problem. The characteristic equation for the eigenvalues of the model problem is obtained, the structure of the spectrum and the asymptotics of the branches of the eigenvalues are studied. Assumptions are made about the structure of the oscillation spectrum of a viscous stratified fluid bounded by an elastic membrane for an arbitrary vessel. It is proved that the spectrum of the problem is discrete, located in the right complex half-plane symmetrically with respect to the real axis, and has a single limit point $+\infty$. Moreover, the spectrum is localized in a certain way in the right half-plane, the location zone depends on the dynamic viscosity of the fluid.

Published: June 2021

Ukraine’s healthcare system faces unprecedented national security challenges in the third wave of the COVID-19 pandemic. A particularly acute issue is countering counterfeit pharmaceuticals, preventing drug shortages, joining efforts of the authorities and national manufacturers of drugs and medical supplies. According to the UN, more than 60 % of the population lives below the poverty line in Ukraine. Timely response to these challenges and taking preventive measures will save lives, minimize the volume and consequences of the pandemic. The paper provides an economic and legal analysis, trends, risks and threats to national security of the state and health protection during a pandemic, in order to protect intellectual property rights, adequate coordination of actions at the national and international levels. The impact of counterfeiting on the criminal landscape in the EU, and also business and economy, is shown based on the analysis of studies by the OECD, the EU Intellectual Property Office (EUIPO) and Europol. The foundations of anti-counterfeiting management, measures to implement a standard anti-counterfeiting strategy are proposed.
