“Surgical Treatment of Degenerative Mitral Valve Disease-Causing Mitral Regurgitation: State Of The Art”
Authors: Talukder Md Faisal
Published: July 2021

Degenerative Mitral Valve Disease (DMVD) is common in developed countries that frequently causes mitral regurgitation (MR). The natural history of DMVD is not well demonstrated. Therefore, timely and suitable interventions are the determinant of post-intervention clinical outcomes, life quality, and life expectancy of patients. The severity of MR can be precisely assessed by doppler-echocardiographic imaging. However, no medical management has been proven to be effective in averting the volume overload related sequel of asymptomatic degenerative MR. Therefore, mitral valve surgery (MVS) is the gold standard treatment strategy for DMVD. Notwithstanding, MVS is the only sorts of treatment strategy which provides long term natural and complication-free clinical outcome to otherwise healthy DMVD patients. However, mitral valve (MV) repair provides better clinical outcomes compared to MV replacement, along with the significant reduction of postoperative mortality rate about 70%. Currently, MVS is carried out using minimally invasive techniques or robotic-assisted techniques. Nonetheless, MVS using percutaneous techniques is evolving in the treatment for DMVD patients. This state-of-the-art-review is aimed to delineate the recent knowledge of DMVD, which includes the natural history of the disease, diagnostic modalities, recent treatment strategies, and clinical follow-up results.
The Impact of Social Media on Italian Shamanism and Folk Magic
Authors: Puca Angela
Published: July 2021

In the last decade, the use of social media has become widespread among all age groups in Italy. Facebook, in particular, has fostered the spreading of information and aided the gathering of like-minded individuals. This process has slowly but steadily affected communities involved with indigenous and trans-cultural shamanism. From the evolution towards a more inclusive and syncretic approach within autochthonous traditions to the wider reception and reinterpretation of imported shamanism, the narratives created online have translated into a tangible change of how practitioners position themselves within the affiliated tradition. By analysing data collected on a Facebook group I created ad hoc for my doctoral research and the content posted on public profiles and groups, I will argue that the use of Social Media reshapes the way practitioners construct their traditions and practices. In the case of vernacular healers, this prompted the development of a shared terminology while fostering a discussion on autenticity among trans-cultural shamans.
Determination of soil and ground sealing in functional zones of Volgograd based on remote sensing data
Authors: Gordienko O. A.
Published: July 2021

The paper presents the results of interpretation of sealed soils and ground for the territory of Volgograd and its various functional zones. Determination of the sealed portion was performed by means of automated method using ENVI 4.7 software by means of QuickBird space image classification using the “maximum likelihood” method. The study objects were the territories of all districts of Volgograd, as well as residential and recreational functional zones. It was found that the sealed surfaces occupy about 169.4 km2 (20.5% of the total area of the city). However, the city districts and functional zones differ significantly in proportion of sealed areas. The most sealed surfaces were those of Tractorozavodsky (24.2%), Voroshilovsky (33.0%), Dzerzhinsky (37.4%), Centralny (45.2%), Krasnooktyabrsky (39.4%) and Krasnoarmeisky (26.6%) districts of Volgograd. Soil cover of the Sovetsky (13.5%) and Kirovsky (12.9%) districts is least sealed. Sealing of functional zones also varies widely. Thus, the highest values of sealing (up to 63%) characterize the multi-, low- and medium-rise constructions zones. A wide range of values (from 26 to 51%) corresponds to the areas of individual residential development, as well as collective gardens and dachas (from 9.6 to 39.5%). In the recreational zone average sealing is at 27.6% level. Thus, the identified share of sealed surfaces on the territory of Volgograd and its functional zones will allow solving effectively the problems of territorial planning in the further implementation of works on gardening and landscaping of urban areas.

EXPERIMENTAL ASSESSMENT OF THE EFFECT OF EXPOSURE LEVEL ON THE RESOLUTION OF A DIGITAL PHOTOGRAPHIC SYSTEM
Authors: Pivtorak Diana
Published: July 2021

While photographing in a wide range of brightness within the frame, the exposure devices must provide exposure control for each elementary area of ​​the frame, i.e., provide local exposure control. Cameras which equipped by well-known exposure devices with local exposure control is used a multiplicative, additive or multifunction method of image recording.
Using of the multiplicative method leads to energy losses in the optical channel, which requires correction of the exposure control parameters. Using of the additive method makes it possible to reduce the effective shutter speed, but reduces the contrast of small images. The multiplicative method of image registration allows to suppress low-informative low-frequency components of the spectrum of the input signal, providing less losses from the image blur according to the multiplicative method and less losses from reducing the contrast of images of small parts according to the additive method.
Comparative evaluation of cameras’ effectiveness which are equipped by exposure devices with local exposure control, which are based on different methods of image registration, is convenient to assess the criterion of "resolution averaged over the frame field". According to the developed methodology of evaluating the effectiveness of this type of cameras, the averaged field resolution can be calculated in several ways, each of which assumes a preliminary calculation or obtaining the dependence of resolution from exposure (resolvometric characteristics of the camera).
The methodology of experimental determination of the resolvometric characteristic of a photographic image recorder equipped by exposure devices of local exposure control is proposed. This methodology is illustrated by the example of measuring the resolvometric characteristics of the digital camera nex-6 for different external conditions. The good convergence of results of theoretical and experimental researches is shown. The proposed methodology can be used in studies of the impact of the process of the multifunction method of image recording on the photographing efficiency.

Published: July 2021

During the control of technological processes of manufacturing various parts, which are required to increase the accuracy of processing, it is necessary to adhere to the systematic measurement of their geometric dimensions, tolerances, compliance with the shape and location of the surfaces of the parts. To date, this type of non-destructive testing is carried out using special optical systems and allows you to study different products, regardless of their type, design features and structure of the materials from which they are made. That is, the visual-optical method of measurement is one of the most important methods of non-destructive testing in production.

In the article the authors shared practical experience in the selection and optimal use of 3D video measuring system with limited resources. The choice of manufacturer and model (type) of video measuring system was made depending on the complexity of the measurement tasks. First of all, the error of measurement results was evaluated, which was determined by technical indicators and the composition of software functionality. For control in the manufacture of high-precision mechanical parts, the basic requirements for technical parameters and software of the video measuring system are defined.

Emphasis is placed on the economic effect by reducing the time of measurement of linear dimensions and angles in the plane of the controlled parts, while using high-quality functionality of video processing, which significantly reduces the likelihood of operator error. The choice between manual and automated measurement systems is justified: the main factors are the capacity and the required amount of measurements. Evaluated as a positive ability to save information files in Exel, Word, and SPC for statistical processing of information to improve the quality of parts.

Features of video measuring systems concerning: implementation of innovative metrological solutions - multisensory metrology, namely - inclusion in the program of measurements of optical, laser and contact research; Reverse Engineering of previous versions of parts for which drawings have already been lost and CAD models are not available.
HARDWARE AND SOFTWARE OF AUTOMATIC CONTROL SYSTEM OF FUEL COMBUSTION PROCESS IN LOW AND MEDIUM POWER BOILERS. PART 1. METHOD AND HARDWARE
Authors: Zaporozhets Arthur , Kuts Yurii
Published: July 2021

In Ukraine today there are more than 6000 boiler plants with a heating capacity of up to 1 Gcal/h with an efficiency of about 70 %, requiring replacement or modernization, 40 % of boilers are operated with an efficiency of less than 82 %, about 11000 boilers with a capacity of 100 kW to 1 MW have been in operation for over 20 years. Although the part of these boilers in the municipal heat power system of Ukraine does not exceed 14 %, the projected savings in natural fuel in these boilers is more than 130 million cubic meters per year. Thus, increasing the efficiency of the fuel combustion process in small and medium power boilers is an urgent task at the present time.

The article presents the results of creating a method and hardware that implements it, to increase the speed and reliability of monitoring the process of fuel combustion in boiler units based on measuring the concentration of residual oxygen in exhaust gases. The developed method is implemented by stepwise correction of the ratio of the air-fuel mixture entering to the furnace of the boiler for combustion, according to feedback signals from a broadband oxygen sensor manufactured by Bosch, located in the outgoing channel.

The air-fuel ratio control with automatic adjustment of the blower fan speed depending on the amount of fossil fuel supplied for combustion ensures low-toxic combustion of fuel with low emissions of nitrogen oxides and carbon monoxide, and high efficiency. Additional use of a variable frequency drive in the combustion control system allows to reduce energy consumption by 30-40 %, eliminate starting currents and motor overloads, reduce mechanical wear of equipment, increase the service life of contact switching equipment. In general, the developed fuel combustion control system allows to optimize the fuel combustion mode, taking into account the actual conditions, operating modes of the boiler unit and fuel characteristics; to reduce specific fuel consumption by at least 10%; to reduce the level of emissions of nitrogen oxides up to 40 % and carbon monoxide up to 50 %; to increase the efficiency by at least 5 %; qualitatively to simplify the work of the boiler maintenance personnel.
THE EFFICIENCY ESTIMATION OF MONITORING THE HUMAN RADIATION DOSES DURING COMPUTED TOMOGRAPHY
Authors: Rudoy Aleksey , Tereshchenko Mykola
Published: July 2021

X-ray imaging techniques have many advantages over other methods because they can be easily performed in a short time and are widely available, allowing doctors to quickly confirm or rule out a diagnosis with greater confidence. The main problem associated with the widespread use of radiological diagnosis and therapy is the significant exposure of patients. Over the last 30 years, the average radiation dose of the population and patients has doubled, despite the fact that exposure to natural factors has remained almost at the same level. The increase in the level of the average radiation dose of the population and patients of medical institutions is associated with an increase in the number of diagnostic procedures, despite the fact that the level of radiation with each procedure has decreased significantly. This is especially true in this period of coronary crisis - a rapid increase in the number of human diseases caused by the Covid-19 virus.

The paper considers the principles of monitoring the level of radiation doses in diagnostic and therapeutic complexes of medical institutions. The analysis of research methods, comparison of doses obtained experimentally, in which multifactor measurements were performed with dosimeters located in the areas of major vital organs and doses adopted by treatment protocols according to state and sanitary rules and regulations.

After the analysis and identification of the main problems of irradiation, a method of automated measurement of radiation doses with the installation of high-precision detectors and an algorithm for calculating irradiation parameters, according to the location of patients and staff during diagnostic or therapeutic procedures, as well as separately for each body, method assessment of the accumulation of the level of radiation doses.
Simulating angular momentum of gravitational field of a rotating black hole and spin momentum of gravitational waves
Authors: Matsuki Yoshio , Bidyuk Petro
Published: July 2021

In this research, we simulated the angular momentum of gravitational field of a rotating black hole and the spin momentum of gravitational waves emitted from the black hole. At first, we calculated energy densities of the rotating gravitational field and spinning gravitational waves as the vectors, which were projected on the spherical curved surface of the gravitational field and of the gravitational waves. Then we calculated the angular momentum and the spin momentum as the vectors perpendicular to the curved surface. The earlier research by Paul Dirac, published in 1964, did not select the curved surface to calculate the motion of quantum particles; but, instead, he chose the flat surface to develop the theory of quantum mechanics. However, we pursued the simulation of the gravitational waves in spherical polar coordinates that form the spherical curved surface of the gravitational waves. As a result, we found that a set of anti-symmetric vectors described the vectors that were perpendicular to the spherical curved surface, and with these vectors we simulated the angular momentum of the rotating black hole’s gravitational field and the spin momentum of gravitational waves. The obtained results describe the characteristics of the rotation of a black hole and of spinning gravitational waves.
Reduction conceptualization of oracle schemes

Published: July 2021

This work is aimed at developing an intersubjective paradigm and an active role of the subject in reduction conceptualization. For this purpose, the general oracular scheme of conceptualization is concretized by the complementarity of composition and decomposition as explications of synthesis and analysis of entities. Pragmatically conditioned enrichment of this complementarity is carried out with the involvement of compositional programming and nominal models of data, functions, and compositions. The oracular scheme of reduction is considered, the meaning of which is that it, based on existing compositions, naturally implements the paradigm of “divide and conquer” in understanding the active role of the subject in conceptualization, supporting the real complementarity of decomposition and compositional methods of conceptualization. Representative examples of reduction conceptualization are shown, which substantiate the technology of solving programming problems.

Published: July 2021

In this article, we assume that the beginning of the universe was before the Big Bang. In the beginning, all matter in the universe was combined in an infinitesimal spherical shape. This sphere was compressed to an incomprehensible value for a period, and then exploded and expanded time and space. We are referring to the negative time before the Big Bang. The evolution of the universe before the Big Bang, passing through the moment of the explosion to the end of the universe at the Big Rip, has been studied. In this article, we try to answer the questions; did the universe exist before the Big Bang? What is the origin of the universe and how did it arise? What are the stages of the evolution of the universe until the moment of the Big Rip? What is the length of time for the stages of this development?

Published: July 2021

Antibiotics are commonly used to treat infectious diseases. However, massive and inappropriate antibiotics usage cause many problems including the emergence and spread of antibiotic-resistant bacteria. To avoid this issue, in modern countries the interest of using probiotics in feed supplementation to promote health and prevent or treat intestinal infectious diseases in companion animals like dogs has been increasing. We evaluate the probiotic potential of Lactobacilli isolated from healthy dogs faeces. The isolated Lactobacilli were first confirmed by 16SrRNA sequencing, then in vitro tests were conducted to assess survival potential of Lactobacilli under simulated gastrointestinal conditions and adhesion ability to gut epithelia, effects on epithelial barrier function, anti-inflammatory activities, effects on defensin peptides (beta-defensin 3) and inhibitory effects on common pathogens. Lactobacilli showed considerable potential to survive in simulated gastrointestinal environmental conditions, low pH, high bile salt concentrations along with good adhesion properties with MODE-K cells. Pathogenic bacterial growth and their adhesion to MODE-K cells was significantly inhibited by Lactobacilli. Real-time PCR analyses further demonstrated that L. acidophilus strain AR1 and AR3 inhibit Salmonella-induced proinflammatory cytokines (IL-6, IL-8, 1ꞵ) production and reinforce expression of tight junction protein (occludin). None of the strain induce mRNA expression of beta-defensin 3 in MODE-K cells. Based on in vitro results the L. acidophilus strain AR1 has potential to be supplemented in canine feed. However, further in vivo studies investigating health-promoting effects are awaited.
Damage Detection on a Beam with Multiple Cracks: A Simplified Method Based on Relative Frequency Shifts

Published: July 2021

Identifying cracks in the incipient state is essential to prevent the failure of engineering structures. Detection methods relying on the analysis of the changes in modal parameters are widely used because of the advantages they present. In our previous research, we have found that eigenfrequencies were capable of indicating the position and depth of damage when sufficient vibration modes were considered. The damage indicator we developed was based on the relative frequency shifts (RFS). To calculate the RFSs for various positions and depths of a crack, we established a mathematical relation that involved the squared modal curvatures in the healthy state and the deflection of the healthy and damaged beam under dead mass, respectively. In this study, we propose to calculate the RFS for beams with several cracks by applying the superposition principle. We demonstrate that this is possible if the cracks are far enough from each other. In fact, if the cracks are close to each other, the superposition method does not work and we distinguish two cases: (i) when the cracks affect the same beam face, the frequency drop is less than the sum of the individual frequency drops, and (ii) on the contrary, cracks on opposite sides cause a decrease in frequency, which is greater than the sum of the frequency drop due to individual damage. When the RFS curves are known, crack assessment becomes an optimization problem, the cost function being the distance between the measured RFSs and all possible RFSs for several vibration modes. Thus, the RFS constitutes a benchmark that characterizes damage using only the eigenfrequencies. We can accurately locate multiple cracks and estimate their severity trough experiments and thus prove the reliability of the proposed method.

Published: July 2021

Diisocyanates, particularly toluene diisocyanate (TDI) are useful for the preparation of various polyurethanes with specific applications as leather-like materials, adhesives, insoles etc. Blocking agents can be used for the operational simplicity and reducing the hazards of TDI. In this paper we reported the use of 3-(4-bromo-phenyl)-1H-pyrazole to block toluene diisocyanate (TDI). FTIR, NMR, thermogravimetric analysis, contact angle and differential scanning calorimetry (DSC) and were used for characterization. Effectiveness of blocking was confirmed by spectroscopic techniques. DSC thermogram shows that blocked adducts deblock at 240 °C causing the regeneration of TDI and blocking agents to react with polyols of different molecular weights forming polyurethanes. The characterization of polyurethanes has been done by Infrared spectroscopy, Nuclear magnetic resonance spectroscopy, thermogravimetric analysis, differential scanning calorimetry and contact angle study.

Null-flux Electro-dynamic suspension (EDS) system promises to be one of the feasible high-speed maglev systems above 600 km/h. On account of its greater current-carrying capacity, superconducting magnet can provide super-magnetomotive force that is required for null-flux EDS system and cannot be provided by electromagnets and permanent magnets. There is already a relatively mature high-speed maglev technology with low temperature superconducting (LTS) magnets as the core, which works in the liquid helium temperature region (T≤4.2 K). 2-Generation high temperature superconducting (HTS) magnet winded by REBa2Cu3O7−δ (REBCO, RE=rare earth) tapes works above 20 K region and do not need to count on liquid helium which is rare on earth. This paper designed HTS no-insulation closed-loop coils applied for EDS system and energized with persistent current switch. The coils can work at persistent current model and has premier thermal quench self-protection. Besides, a full size double-pancake module was designed and manufactured in this paper, and it was tested in liquid nitrogen. The double-pancake module’s critical current is about 54 A and it is capable of working at persistent current model, whose average decay rate measured in 12 hours is 0.58%/day.

Published: July 2021

Deep neural networks (DNNs) have made a huge impact in the field of machine learning by providing unbeatable humanlike performance to solve real-world problems such as image processing and natural language processing (NLP). Convolutional neural network (CNN) and recurrent neural network (RNN) are two typical architectures that are widely used to solve such problems. Time sequence-dependent problems are generally very challenging, and RNN architectures have made an enormous improvement in a wide range of machine learning problems with sequential input involved. In this paper, different types of RNN architectures are compared. Special focus is put on two well-known gated-RNN’s Long Term Short Memory (LSTM) and Gated Recurrent Unit (GRU). We evaluated these models on the task of force estimation system in pouring. In this study, four different models including multi-layers LSTM, multi-layers GRU, single-layer LSTM and single-layer GRU) were created and trained. The result suggests that multi-layer GRU outperformed other three models.

A method was developed to perform shape optimization of a tidal stream turbine hydrofoil using a multi-objective genetic algorithm. A bezier curve parameterized the refrence hydrofoil profoil NACA 63815. Shape optimization of this hydrofoil maximized its lift-to-darg ratio and minimized its pressure coefficient, thereby increasing the turbines power output power and improving its cavitation characteristics. The Elitist Non-dominated Sorting Genetic Algorithm (NSGA-II) was employed to perform the shape optimization. A comparative study of two-and three-dimensional optimizations was carried out. The effect of varing the angle of attack on the quality of optimized results was also studied. predictions based on two-dimensional panel method results was also studied. Preditions based on a two-dimensional panel method and on a computational fluid dynamics code were compared to experimental measurments.

The Snooker Algorithm for Ultrasonic Imaging of Fatigue Cracks in order to use Parameter-Spaces to Aid Machine Learning
Authors: Nageswaran Channa
Published: July 2021

Fatigue cracks in a wide array of industrial components and structures pose a significant threat to their integrity. Detecting fatigue cracks using ultrasonic inspection techniques is a widespread activity for economic reasons but there are limitations to the techniques due to the morphology of fatigue cracks. In addition to detection there is a need to measure the size of the cracks which are often within the volume of the material. Ultrasonic techniques are well-suited to look inside the volume of the material but achieving sufficient sensitivity to the tip of the cracks in particular is practically difficult. Without an accurate knowledge of where the tip of the crack lies there can be significant uncertainty in sizing measurements. Machine Learning (ML) techniques are being developed to aid in the inspection and monitoring tasks but presenting the ultrasonic data in a suitable way for machine learning is very important. This paper presents a new approach to condition the ultrasonic data for machine learning settings so that they can be used effectively and confidently to detect and size fatigue cracks. The new approach, using images termed parameter-spaces, will also aid in conventional inspections as they are able to give information to human operators as to the existence or not of these very dangerous cracks.
BIOACCUMULATION OF METALS AND EVALUATION OF GOLDEN MUSSELS ENCRUSTED ON DIFFERENT SCREENS OF NET CAGES
Authors: BESEN Mateus Antonio , MARENGONI Nilton Garcia
Published: July 2021

This study aimed to evaluate the characterization and bioaccumulation of metals of the golden mussel encrusted in the screens of net cages installed in the reservoir of Itaipu Binacional. The experimental design was completely randomized, composed of two types of screens (PVC and Bezinal) distributed on four sides (Sides I, II, III, and IV) of the net cage. The total mass, the average mass, and the dimensions (width, height, and length) of the mollusks were evaluated. The mussels adhered to the Bezinal screen presented a higher average mass, length, height, and width than those colonized on the PVC screen (p <0.05). However, the PVC screen provided a greater (p <0.05) total mass of encrusted mussels. Regardless of the screen used, the average mass and length of mussels had higher values on Side I (p <0.05) than to the Sides II and IV, but not different from Side III. The mussels evaluated showed high levels of metals, and those encrusted in the Bezinal screen presented higher levels of Al, Zn and Cr than the individuals on the PVC screen (p <0.05). The use of a Bezinal screen is more efficient than a PVC screen, as an antifouling material. Mussels with shorterlengths had a higher incidence on the PVC screen. The mussels encrusted in the Bezinal screen bioaccumulate higher content of Al, Zn, and Cr. The type of screen used in the net cages influences the mass and size of adhered mussels, as well as can interfere with the metal accumulation in the golden mussel.

Ketersediaan air bagi tanaman pertanian sangat fluktuatif yang dipengaruhi oleh musim, lokasi sumber air, serta usaha-usaha konservasi air. Penyediaan air bagi lahan pertanian dapat diusahakan dengan pemberian irigasi, yang dimana dalam pemberian air irigasi pada lahan harus mengetahui laju infiltrasinya agar tidak terjadi run-off. Infiltrasi merupakan bagian yang penting dalam siklus hidrologi maupun dalam proses pengalihragaman hujan menjadi aliran di sungai. Pengukuran laju infiltrasi dilakukan dengan banyak metode salah satunya adalah dengan metode pengukuran langsung yaitu menggunakan Double Ring Infiltrometer dan dengan metode Horton. Tujuan penelitian ini adalah mengetahui laju infiltrasi yang terjadi di kebun percontohan Fateta Unipa. Metode yang akan digunakan adalah metode deskriptif analisis dengan pendekatan kuantitatif. Pengukuran laju infiltrasi di lapangan dilakukan pada 1 (satu) titik dengan 3 (tiga)kali ulangan. Pengolahan data dilakukan dengan 2 (dua) teknik pengolahan, yaitu dengan metode pengolahan data hasil pengukuran lapang secara langsung dan pengolahan data dengan menggunakan Model Horton.
