Authors: Yang Guofang , Jia Xiangru , Zhao Yabin , Ho Xinguang , Song Changzhong , Zhang Zijun
Published: January 2021

Coal gangue and sunflower straw biomass from Xilingguole, Inner Mongolia, China and Ulanqab Tsining District, Inner Mongolia, China, respectively, were burned separately and mixed in different proportions. The synergistic effect was analyzed by comparing the actual mixed combustion curve with the theoretical mixed combustion curve. The bar chart and TR (the mean of the difference between the experimental and calculated was divided by the mean of the calculated values) value curve were used to show the synergistic effect. The results showed that the synergistic effect of coal gangue and sunflower straw was optimal when the ratio (sunflower straw:coal gangue) was 2:8.

Authors: Verly Lopes Dercilio Junior , Bobadilha Gabrielly dos Santos , Grebner Karl Michael
Published: January 2021

This study reports the feasibility of using deep convolutional neural networks (CNN), for automatically detecting knots on the surface of wood with high speed and accuracy. A limited dataset of 921 images were photographed in different contexts and divided into 80:20 ratio for training and validation, respectively. The “You only look once” (YoloV3) CNN-based architecture was adopted for training the neural network. The Adam gradient descent optimizer algorithm was used to iteratively minimize the generalized intersection-over-union loss function. Knots on the surface of wood were manually annotated. Images and annotations were analyzed by a stack of convolutional and fully connected layers with skipped connections. After training, model checkpoint was created and inferences on the validation set were made. The quality of results was assessed by several metrics: precision, recall, F1-score, average precision, and precision x recall curve. Results indicated that YoloV3 provided knot detection time of approximately 0.0102 s per knot with a relatively low false positive and false negative ratios. Precision, recall, f1-score metrics reached 0.77, 0.79, and 0.78, respectively. The average precision was 80%. With an adequate number of images, it is possible to improve this tool for use within sawmills in the forms of both workstation and mobile device applications.

Authors: Sang Yizhou , McQuaid Michael , Englezos Peter
Published: January 2021

Response surface methodology was used with four factors to screen for the best starch and optimize the use of chemicals in order to maximize precipitated calcium carbonate (PCC) filler retention in a peroxide-bleached TMP suspension. Three commercial starches were used in conjunction with colloidal silica and flocculant. The PCC loading level and the interactions between PCC level, starch, flocculant, and silica were investigated, and empirical models were constructed. The empirical process models were then employed to predict the retention and drainage. It was found that medium-charged cationic starch (S858) gave the highest total and filler retention, whereas high-charged cationic starch (S880) resulted in the best drainage. The ash content of the handsheet can be pushed up to 40% using the retention system with medium (S858) and high (S880) charged cationic starch. The high-charged cationic starch (S880) gave stronger paper, probably because of its higher affinity with the fiber and fines.

Immunogenicity and duration of immunity of the polyvalent vaccine against chicken salmonellosis
Authors: Sen О. М. , Saliy О. О. , Mazurkevych V. I. , Sobko Y. A.
Published: January 2021

Poultry salmonellosis causes serious economic damage and must be prevented by disinfection, zoohygienic measures or by vaccination. To develop a new polyvalent vaccine against poultry salmonellosis, we used bacterial strains of Salmonella enteritidis, S. typhimurium and S. gallinarum. Antigenic and immunogenic efficacy of the vaccine was tested on specific-pathogen free chickens, which were divided into five groups of 10 birds in each group and were vaccinated intramuscularly at 8 and 12 weeks: group A (non-immunized control), group B (S. enteritidis mono-vaccine), group C (S. typhimurium mono-vaccine), group D (S. gallinarum mono-vaccine) and group E (trivalent vaccine Polimun Salmo). None of the immunized birds showed such adverse reactions as abnormal behaviour, mortality or signs of anorexia, depression or diarrhea. Two weeks after the revaccination, 5 birds in each group were challenged by watering 3 cm3 of working suspensions of S. gallinarum, S. typhimurium and S. enteritidis control strains at a concentration of 1 × 109 CFU. 72 h after the challenge, faeces were collected from all chickens in each group to identify Salmonella excretion with faeces, and the chickens were euthanized. Significant protection against the virulent challenge was observed in all immunized groups based on mortality and post-mortem lesions compared with the non-immunized control group. Blood samples were selected weekly from 5 chickens of each group for 184 days. The antigenic efficacy of the vaccines was studied by reaction of haemagglutination in the obtained serum. The potent antigen-specific response to lymphocyte activation found in all immunized groups indicated the induction of immune responses. Overall, the results showed that persistent immunity is formed in 4 weeks after the revaccination and lasts for a productive period. Immune response of chickens on day 184 after vaccination with Polimun Salmo was 1: 647, indicating that the developed polyvalent vaccine against common serovars of S. enterica in poultry is effective and immunogenic and can be further used in field studies.
Risk factor analysis for congenital heart defects in children
Authors: Lastivka I. V. , Pishak V. P. , Ryznychuk М. О. , Khmara Т. V.
Published: January 2021

Congenital heart defects (CHDs) are the most common malformations, occurring in almost 1.0 in 100 births. We investigated an association between risk factors and CHDs, because epidemiological studies have reported conflicting results regarding risk factors and CHDs recently. The study of CHD frequency was conducted in Chernivtsi region (Northern Bukovina) on the basis of the medical genetic center. A retrospective method of research by studying registration genetic maps was used to analyze risk factors. 91 cards of infants suffering from CHD (47 boys and 44 girls) aged 0–1 living in the territory of Northern Bukovina were selected. In order to identify risk factors, 133 cards of healthy infants (77 boys and 56 girls) were used. The analysis of risk factors revealed that the female gender of a child is a risk factor for CHD development. The analysis of the ordinal number of pregnancy revealed that the second and the third pregnancies are probable risk factors for the development of this pathology. It was found in our study that folic acid intake during the first trimester prevented CHD development (OR 2.33). The study revealed that among stressful risk factors are: unplanned pregnancy (OR 3.13); out-of-wedlock pregnancy and stress during pregnancy. Maternal CHD increased the CHD development in offspring approximately by two times. Some factors, such as a woman doing hard physical work during pregnancy, having sedentary work during pregnancy, the mother being a housewife or having an incomplete secondary education (OR 3.61), the mother’s secondary education, the father’s incomplete secondary education (OR 18.62), the father serving in the army (OR 2.15) or being a student at the time of woman’s pregnancy (OR 2.97) were significant for CHD development in the fetal stage. A young age of the father (up to 43 years) was also considered as one of the risk factors. This article is expected to provide timely information on risk factors for CHD development to a wide range of medical staff, including pediatric and adult cardiologists, pediatricians, thoracic surgeons, obstetricians, gynecologists, medical geneticists, genetic counselors and other relevant clinicians.
CHALLENGES FACING BANKING SUPERVISION AND ACCOUNTING IN CONTEMPORARY ECONOMIC SITUATION
Authors: Ivanov Nikolai
Published: January 2021

In recent decades there has been a dynamic process of political and economic liberalization, internationalization and globalization. Quite normally business development follows the general trend of the "opening" of markets, economic diffusion processes can be found at all levels, and the "intertwining" of national and foreign capital is considered natural course of economic development. The role of the banking sector in the development of any economy is undoubtedly important, but the whole process would not have been possible without the involvement of banks. In the light of the above, given the current economic crisis realities, given the financial sector in the creation of today's economic reality, the main goal of the study is to outline the challenges facing the banking supervision and bank accounts in relation to the sustainable development of the sector and national economy.
SITUATION AND PROSPECTS OF CUSTOMS POLICY AND AGENCY IN BULGARIA
Authors: Nencheva - Ivanova Iskra
Published: January 2021

The intense and multilateral development of international trade requires that optimal strategies are introduced into customs practice to simplify and speed up the customs process. The alignment of international customs legislation and the consolidation of unified technologies to customs control is a global trend validating in favor of current customs administrations and contemporary international trade patterns.
The development of this process requires the use of various forms of mediation between the trader and the customs authority. They appear to be an objective need of both sides in these relationships. The dynamics of the external trade flows presupposes that customs clearance takes place within regulated deadlines and at different geographic points, which of course necessitates a knowledge of at least two customs laws because the contemporary aspects of international economic relations have long gone beyond bilateral relations.

The aim of the study was to draw attention to the danger of vitamin D overdose. The beneficial effects of vitamin D are described in both scientific literature and popular science journals. On the other hand, papers on the symptoms of excess intake of vitamin D are scarce. Since vitamin D preparations are easily accessible, they are widely used in both adults and children without any medical supervision. We present a case of a 2-year-old boy with life-threatening hypercalcaemia due to excess vitamin D intake. The boy required prolonged hospital stay, intensive therapy to reduce blood calcium, complex pharmacotherapy and hemofiltration. Abdominal ultrasonography performed after therapy completion showed enlargement of both kidneys and persistent hyperechogenicity of renal cortex. Expert recommendations specify the route of administration and the dose of vitamin D. In the era of the Internet, however, opinions suggesting doses that are inconsistent with recommendations may be found. Such management may have serious health consequences and even be life-threatening in some cases.

Sakrament chrztu w świetle średniowiecznych ksiąg pokutnych
Authors: Story Marek
Published: January 2021

Księgi pokutne, które powstały w epoce późnej starożytności chrześcijańskiej i wczesnego średniowiecza, są świadectwem kształtowania się praktyki pokutnej w Kościele. Celem artykułu jest ukazanie w świetle tychże ksiąg różnych praktyk, także tych niewłaściwych, związanych z sakramentem chrztu, które powodowały obciążenie winnych dotkliwymi karami – pokutami wymagającymi odpowiedniego zadośćuczynienia, często trudnego do wykonania.W księgach pokutnych zwracano szczególną uwagę, że dziecko powinno zostać ochrzczone jak najszybciej, zwłaszcza w sytuacji, kiedy chorowało. Nakazywano ponadto spowiednikom, aby weryfikowali w ramach spowiedzi czas, w którym rodzice przynosili dziecko do chrztu. Penitencjały zwracają także uwagę na kwestię, kiedy sakrament chrztu, jest ważnie udzielony, a kiedy nie. Podkreślano, że chrzest ważnie udzielony nie może zostać ponowiony. W niektórych księgach pokutnych znajdujemy natomiast błędne rozumienie zależności życia moralnego szafarza i ważności udzielanego sakramentu. Pojawia się także zagadnienie, kto może pełnić rolę rodzica chrzestnego, jak i omówienie przeszkody pokrewieństwa duchowego mającego swe korzenie w analizowanym sakramencie.

This paper falls within the framework of the security of satellite images, in particular interferograms from an Interferometric Synthetic Aperture Radar (inSAR) system. The innovation of this work consists in the application of a cryptosystem based on two algorithms Advanced Encryption Standard (AES) and the Rivest, Shamir and Adleman (RSA) encryption algorithm for securing interferograms of inSAR systems. AES employs five encryption modes Electronic Code Book (ECB), Cipher Bloc Chaining (CBC), Cipher FeedBack (CFB), Output FeedBack (OFB), and counter-mode encryption (CTR). The use of the AES algorithm alone can only ensure the confidentiality function. In the proposed cryptosystem confidentiality is ensured by the AES algorithm, authenticity is guaranteed by the RSA algorithm, and integrity is ensured by two parameters; the correlation function between the adjacent pixels and the SSIM parameters (structural similarity index SSIM). For evaluation and analysis of security performance for interferogram encryption, several test metrics are employed. These metrics are: Analysis of histograms of the encrypted interferograms, correlation between the adjacent pixels, between the original interferogram and the encrypted interferogram, SSIM between the original interferogram and the decrypted one. Moreover, we exploit the analysis of resistance to error propagation for the five modes. The obtained results show a superiority of the OFB and CTR modes for the encryption of inSAR interferograms compared to ECB, CFB, and CBC modes. It is noteworthy, that the main criteria that can be used to choose between OFB and CTR for encryption of satellite images are propagation of errors and the complexity material for their locations on the edges of the satellites propagation of errors and the complexity material for their locations on the edges of the satellites. OFB mode is employed in satellites to minimize the number of on-board circuits, which is decisive for satellites. CTR mode is recommended by the CCSDS (Consultative Committee for Space Data Systems) for telemetry (TM) and remote control (TC) encryption.

The studied system contains a photovoltaic conversion chain with a total power of 7.2 kW, a wind conversion chain (5.1 kW), two-level inverter related to the electrical grid through an RL filter. The control systems of the simulation model include the Model Predictive Controller (MPC), which is mainly applied for both DC/DC converters and three-phase inverter. The MPC strategy uses the mathematical model of the considered power converters in order to predict the possible future behaviors of the different controlled variables. It permits selecting the optimal voltage vector, which is able to ensure a minimization of the specified cost function. Modeling and simulation are achieved using PSIM software in order to verify the system’s performances, highlighting many scenarios of varying meteorological conditions. The simulation responses prove that the proposed MPC algorithm can offer a fast transient response, an accurate reference tracking, a high-injected power quality with a low current THD (less than 1% in the steady state).

This study aims to develop a web-based system that evaluates the teaching process based on the course learning outcomes. It includes the active involvement of both the course teacher and the enrolled students on the course. Usually, the teacher delivers the course contents by following the course specification and the course learning outcomes. Here, the teacher is a source of equipping students with all the necessary information about the course and the assessment policies. The students participate in the scheduled assessments, and the teacher evaluates students’ performances based on the course learning outcomes. Significantly, the presented study applies the ordinal scale method for evaluating the students’ performances in the conducted assessments. The students’ performances are measured, and the outcomes help the teacher understand the students' learned skills of the course. Further, the result of the measured outcomes uses for the program performance evaluation at the end of the academic cycle. The presented approach is easy to adapt for any academic course in higher education and enables an effective approach for performance evaluation.

Authors: Tosun Cansu
Published: January 2021

Romantic relationship quality is affected by a number of individual and environmental factors. In evaluation process of romantic relationship, individual’s criteria and the resources that create these criteria have great importance as well. The main purpose of this study was to investigate the correlations among perceived parental relationship behaviors, dyadic perfectionism in romantic relationships, and relationship quality. The research sample comprised 246 students who studied in different departments at Trabzon University and had a romantic relationship at that time. As a result of the analysis, significant correlations were found between the perceived parental relationship behaviors and dyadic perfectionism in romantic relationships, and relationship quality. In addition, it was determined that order and social support scores of females were significantly higher than males. In line with the results, the previous studies reveal that negative patterns between parents and perfectionistic tendencies in relationships negatively affect romantic relationships.

Well-trained teachers will also lead to an increase in the quality of education. A well-trained teacher is expected to have a high motivation on many issues. The motivation to teach is one of the types of motivation that a teacher should have in the education and training process. Interest and aptitude to teach are among the determining factors of the motivation to teach. There are many variables associated with the motivation to teach. One of them is the anxiety of not to be appointed which can be described as the anxiety about not being employed as a result of the education received. The aim of this study was to determine the effect of pre-service teachers’ anxiety of not to be appointed on their motivation to teach. To this end, this study was conducted in the relational screening model with pre-service teachers studying in the final year of Fırat University Faculty of Education and in the pedagogical formation education program of the same faculty. As a result of the study, it was determined that pre-service teachers’ motivation to teach and anxiety of not to be appointed were high. Another result was that pre-service teachers’ motivation to teach decreased as their anxiety of not to be appointed increased.

Impact of Fiscal Policies on Western Balkan SMEs’ Growth: Evidence from Kosovo
Authors: Jusufi Gezim , Gashi-Sadiku Fillorete
Published: January 2021

This paper analyses the impact of fiscal policies on increasing the capacity of SMEs from the manufacturing sector in the Western Balkans, with particular emphasis on those in Kosovo. To achieve empirical results, the data obtained from the opinions of the 100 analysed SMEs were pro­cessed through logistic regression. The SPSS statistical software was also used for these statistics. Based on literature review and empirical results, it has been concluded that fiscal policies have an impact on Kosovo SMEs growth. Also in Kosovo and in other Western Balkan countries, fiscal poli­cies and packages have been adopted to support SMEs and have had a significant effect on their activities. Despite the fact that under normal circumstances fiscal support for SMEs has been provided by the governments of these countries, in the near future there should be greater fiscal support to SMEs by means of fiscal incentives due to the devastating effects of the COVID 19 pandemic on each country’s economy.

The aim of the investigation was to describe a clinical case of the development of interstitial lung lesions in a 57-year-old man with a large left atrial myxoma, which had a reverse development after myxomectomy.

Materials and methods. Patient V., 57 years old, was hospitalized in the therapeutic department of the City Clinical Hospital No. 1 named after N. I. Pirogov in connection with bilateral polysegmental pneumonia. A month before hospitalization, he underwent an outpatient examination for progressive dyspnea. Myxoma of the heart was diagnosed. Due to the progression of respiratory failure and the appearance of fever, he was hospitalized. Amidst the multistage antibiotic therapy, there was a torpid course of lung pathology with syndromes of bilateral dissemination and “ground glass”, bilateral lymphadenopathy of the mediastinum, high pulmonary hypertension, and systemic inflammatory reaction syndrome. Thromboembolism of the branches of the pulmonary artery, tuberculosis, sepsis, infective endocarditis, neoplastic processes of pulmonary and other localization were excluded.

Results. The clinical picture corresponded to interstitial lung lesions within the framework of paraneoplastic syndrome in heart myxoma. It was decided to urgently carry out myxomectomy.

Conclusion. The clinical case demonstrates the development of a rare variant of paraneoplastic syndrome in left atrial myxoma, which was suspected during the patient’s treatment for bilateral polysegmental pneumonia. The progression of the pulmonary lesion was explained by active interstitial inflammation and was supported by the immunological activity of the heart tumor.

The performed myxomectomy, despite the persisting syndrome of systemic inflammatory reaction and infiltration of the lung tissue, led in 2 weeks to complete resolution of interstitial lung lesions and pulmonary hypertension, which confirmed the causal relationship between myxoma of the heart and involvement in the pathological process of the lungs.
A new species of the enigmatic shark genus Nanocetorhinus (Chondrichthyes) from the Oligocene of Austria with palaeoceanographic implications
Authors: Feichtinger Iris , Pollerspöck Jürgen , Harzhauser Mathias
Published: January 2021

Deep-neritic sediments of the Eferding Formation (Egerian, Upper Oligocene) of Upper Austria from the Kamig kaolinite quarry revealed minute teeth of the putatively planktivorous shark genus Nanocetorhinus. This is the oldest unambiguous record of this rarely documented genus, which was known so far only from Miocene deposits of Europe, North America and Japan. Based on previous studies, which showed a positive correlation between sediments of nutrient rich waters and plankton blooms with a majority of ichthyoliths of Keasius and Nanocetorhinus, we argue for a filter-feeding and migratory lifestyle of the latter. Thus, it is supposed that Nanocetorhinus migrated seasonally for foraging, in a similar way to the extant basking shark Cetorhinus maximus. This mode of life and the wide paleogeographic distribution of the open marine genus Nanocetorhinus requires a deep and fully marine connection between the Paratethys and the Proto-Mediterranean Sea during late Oligocene times, which might have been established via the Slovenian Corridor.
A Middle Pleistocene steppe bison find within the Dürnstein Castle (Wachau, Lower Austria)

Published: January 2021

In the course of foundation works in the Dürnstein Castle cervical and front leg bones of a large Bison priscus bull were discovered in fluvial sediments. The small city of Dürnstein with its medieval centre is part of the UNESCO Wachau Cultural Landscape and is built mainly on Palaeozoic basement rocks. The find location is completely overbuilt, but remnants of fluvial sediments on the bones together with the altitude of the site approximately 17 m above the Danube point to a Middle Pleistocene fluvial aggradation level not younger than ca. 240,000 years, and the maximum age is 400,000 years. The fossil bearing location is interpreted as a small sandy bay of the Pleistocene Danube, protected from later degradation and erosion. Morphometric comparisons and taphonomic analyses of the bones allow the reconstruction of a scenario in which the bison probably had drowned in a flood and its carcass was buried quickly before destruction by scavengers or erosion. The study includes a comparison with bison specimens of an unpublished small megafaunal assemblage from adjacent Krems-Kreuzbergstraße. Processing marks on parts of these bones point to an anthropogenic Middle Palaeolithic influence and translocation. In addition, a tentative chronological sketch of the regional Bison species succession (B. menneri, B. schoetensacki, B. priscus) from the Early to the Late Pleistocene is presented.
