Purpose: Chronic otitis media (COM) is one of the common infectious diseases of the middle ear caused by bacterial or viral pathogens. The purpose of the present study was to investigate the efficacy of boric acid (BA) in the treatment of COM by comparing topical 4% and 8% BA applications with systemic ciprofloxacin in a Pseudomonas aeruginosa (P. aeruginosa) inoculation-induced model of COM in rats.

Materials and Methods: Forty-two Sprague Dawley rats were divided into seven equal groups. The COM model was created with P. aeruginosa. Clinical, histopathological and, immunohistochemical comparisons were performed between the control, COM, topical 4% and 8% BA treatment, a systemic ciprofloxacin treatment, and topical 4% and 8% BA contact groups.

Results: In the COM model, moderate edema, inflammation, degeneration and moderate tumor necrosis factor-alpha (TNF-α) expression were detected with the application of 4% BA. Mild edema, inflammation, degeneration, and mild TNF-α expression were detected with 8% BA application.

Conclusion: Both 4% and 8% BA treatment provided significant clinical, histopathological and immunohistochemical improvement. The application of 8% BA was found to exhibit greater therapeutic efficacy, with no harmful effect on the middle ear mucosa.

Published: September 2022

In the quality analysis of contemporary industrial production of praseodymium-neodymium (Pr-Nd) alloys, the amount of carbon content is mainly determined using chemical analysis methods. To overcome the shortcomings of the long durations and high costs of quality inspection cycles,
this study proposes a non-destructive model for determining the carbon content of Pr-Nd alloys using acoustic emission signals collected using a mel frequency cepstral coefficient (MFCC) long short-term memory (LSTM) network (MFCC-LSTM) model and a data acquisition system. The MFCC ensures
accurate signal feature extraction and data dimensionality reduction and the LSTM enables learning of the extracted features. The recognition rate of the MFCC-LSTM model reaches up to 97.53%, which can satisfy the quality inspection requirements for the industrial production of Pr-Nd alloys.
In model evaluation, the receiver operating characteristic (ROC) curve shows good performance indices, indicating that the model is robust. Real-time verification of the model shows that the proposed method greatly shortens the time of each quality inspection link; the quality inspection time
for a single piece of Pr-Nd alloy is only 0.3-0.65 s, which is a good real-time parameter.

Published: September 2022

Valves and other actuators may fail and cause economic losses or safety accidents. To ensure the stable operation of a control system, it is necessary to identify the failures of various valves and carry out the corresponding maintenance. Several methods are designed and implemented
for valve fault diagnosis in this paper. In particular, a novel fault diagnosis method based on a time-series convolution network (FDM-TSCN) is proposed, which is built on a time-series data feature extracting and convolutional neural network. FDM-TSCN can classify 18 out of 19 types of fault,
while many other methods cannot. This algorithm is presented in detail and implemented as a prototype system. Comprehensive simulations are performed on valve fault datasets that are generated by the development and application of methods for actuator fault diagnosis in industrial systems
(DAMADICS). The simulation results prove the effectiveness and superiority of the proposed FDM-TSCN method. All of the source codes and related data in the paper are made available, which enables other researchers to verify the work easily and may inspire them to carry out more informed research.
Fault Orientation and Relocated Seismicity Associated with the 12 December 2018 Mw 4.4 Decatur, Tennessee, Earthquake Sequence
Authors: Daniels Clara , Peng Zhigang
Published: September 2022

Small-to-moderate size earthquakes have occurred along the Eastern Tennessee Seismic Zone (ETSZ) for decades, resulting in the second highest seismicity rate in Central and Eastern United States following the New Madrid Seismic Zone. However, the underlying tectonic setting of seismicity in the ETSZ remains unclear. The recent December 2018 Mw 4.4 earthquake near Decatur, Tennessee, provides an opportunity to study one of the largest recent events in this region, after the 2003 Mw 4.6 Fort Payne, Alabama, earthquake. Here, we use a matched filter technique to detect additional microearthquakes around the Mw 4.4 mainshock. We create templates from 967 cataloged earthquakes spanning over 15 yr (January 2005–July 2020) in the ETSZ. These templates are used to detect missing events four weeks before to four weeks after the mainshock. We calculate the magnitudes of new events using principle component fitting between templates and newly detected events. Two relocation algorithms, XCORLOC and hypoDD, are used comparatively to relocate detected events. We construct focal mechanism solutions for earthquakes around the mainshock using HASHpy, and refine the focal mechanism and depth solution of the mainshock using the cut-and-paste method. The mainshock appears to have occurred at a depth of approximately 5–6 km, which is deeper than the decollement (4–5 km) that separates the Grenville-age basement rock and the Paleozoic sedimentary rock. In addition, the mainshock appears to rupture bilaterally along an east–northeast-trending strike-slip fault, which is consistent with the relocated aftershock locations and one of the nodal planes of the mainshock. The occurrence of the 2018 Mw 4.4 mainshock at a relatively shallow depth and its close proximity to the Watts Bar Nuclear Power Plant highlight the need to reevaluate seismic hazard associated with moderate-size earthquakes along the ETSZ.

Dimensionless and criterial complexes are successfully used in many technical fields. They play an important role in research and design. There are a large number of dimensionless and criterial complexes, which have their advantages and are chosen depending on the topic and specific objectives of the study. The article considers dimensionless and criterial complexes most often used in studies of turbomachines, in particular vortex expansion machines - relative internal (isoentropic) efficiency, degree of pressure drop, adjusted wheel speed, speed coefficient, adjusted diameter, flow factor and coefficient. The authors processed the data of the experimental study of the turbogenerator with a peripheral-side channel and presented them in the form of graphical dependences using these complexes. The improvement of these energy-saving turbogenerators is important because they are used to generate electricity from excess gas pressure, are considered environmentally friendly and are needed for the development of distributed energy. Vortex expansion machines with a peripheral-lateral channel are also poorly understood, so the topic is relevant. In this study, their area of use was determined and reflected in the ns - Ds diagram among radial and other vortex expansion turbomachines to facilitate their comparison and design.

Authors: Fang Lingling , Liu Yu , Qiu Junfeng , Wan Weiqing
Published: September 2022

The rising global incidence of cancer and high attrition rates of anticancer drugs make it imperative to design novel screening platforms to increase the success rate of chemotherapeutic agents. Advances in cell culture models from two-dimensional to three-dimensional platforms, along with microfluidics, have resulted in the creation of tumor-on-a-chip technology, which enables high-throughput molecular screening and helps to simulate the dynamic tumor microenvironment. Furthermore, advancements in bioprinting have allowed the structural and physiological aspects of the tumor to be recreated accurately and help to mimic cell-cell interactions and cell-extracellular matrix. This paper provides a comprehensive review of three-dimensional bioprinting to fabricate a tumor-on-a-chip platform to advance the discovery and screening of anticancer agents and provides a perspective on the challenges and future directions associated with the adoption of this technology to advance cancer research.

Precise and shape-matching osteotomy models are determinants of the experimental homogeneity in the assessment of orthopedic biomechanical properties. At present, however, publications on detailed description of osteotomy in bone biomechanical study are scanty. The purposes of this study were to design a new method of osteotomy-aided module production for bone biomechanical study with the help of three-dimensional (3D) printing and computer-aided design (CAD) and to test the accuracy of osteotomy. Fourteen fourth-generation composite femurs were analyzed. The composite bone was scanned using computed tomography (CT) scanner and loaded in Mimics for reconstruction and, then, imported into 3-Matic software to design intertrochanteric region, distal femur, and rotation control lever models. 3D printer was used to print each component. After assembling Sawbones and osteotomy modules, a horizontal band-saw was used to create fracture models. The volume and mass of intermediate fragments were calculated and analyzed. Satisfactory osteotomies of all composite Sawbones were achieved. The mean volume and mass of intermediate fragments were 21.0 ± 1.5 mm3  and 19.0 ± 1.2 g, respectively. Range of deviation from average of volumes was −1.9 – 2.8 mm3 and most of these deviations fall within the range of −1.4 – 2.1 mm3 . Range of deviation from average of mass was −2.0 – 1.6 g and most of these deviations fall within the range of −1.4 – 1.6 g. One-dimensional histogram of deviation from average shows the precise and stable osteotomy performed based on the modules accordingly. A new method of osteotomy-aided module production for bone biomechanical study with the help of 3D printing and CAD was designed and the accuracy of osteotomy was verified. This method is expected to achieve homogeneity and standardization of osteotomy in bone biomechanical study

Published: September 2022

While the tension of COVID-19 is still increasing, patients who recovered from the infection are facing life-threatening consequences such as multiple organ failure due to the presence of angiotensin-converting enzyme 2 receptor in different organs. Among all the complications, death caused by respiratory failure is the most common because severe acute respiratory syndrome coronavirus 2 infects lung’s type II epithelial, mucociliary, and goblet cells that eventually cause pneumonia and acute respiratory distress syndrome, which are responsible for the irreversible lung damage. Risk factors, such as age, comorbidities, diet, and lifestyle, are associated with disease severity. This paper reviews the potential of three-dimensional bioprinting in printing an efficient organ for replacement by evaluating the patient’s condition.
The Role of Islamic Religiosity on the Relationship Between Risk, Trust, and Intention to Use Digital Payments During the COVID-19 Pandemic
Authors: Sutarso Yudi
Published: September 2022

There has been limited study on risk perception faced by digital payment customers, particularly during the COVID-19 pandemic, motivating this study to analyze the role of risk and trust on the intention and use of digital payments and confirm the moderating role of Islamic religiosity in the model. This study used the Partial Least Squares -Structural Equation Model (PLS-SEM) method, including a survey of 270 customers of three digital payment service providers: OVO, Gopay, and Dana. The key finding revealed that security and operational risks significantly impacted trust, even though they did not affect the intention to continue. Another significant result uncovered that Islamic religiosity moderated the effect of operational risk on trust. In this case, customers with a lesser religiosity level were more sensitive to the risk's impact. The significant contribution of this study is an expanding theory on the relationship between perceived risk, trust, and the use of digital payments. The study also offers recommendations to practitioners on managing risk and trust to increase the likelihood of using digital payment in the future. Furthermore, practitioners must consider religiosity regarding risk management, trust, and consumer protection.

Authors: Sari Indah Permata , Birton M Nur A , Muluk M Adrian
Published: September 2022

Research aims: This study aims to critically analyze the account administration of confiscated funds from criminal cases at the Public Prosecution Service of the Republic of Indonesia using three-dimensional Isomorphism of DiMaggio Powel’s New Institutional Theory. Design/Methodology/Approach: We employ qualitative approach using three-dimensional Isomorphism of DiMaggio Powel’s New Institutional Theory; coercive pressure, mimetic pressure dan normative pressure. We interviewed 21 informants including officials from Special Crimes and General Crimes Section who are responsible for the account administration of confiscated funds. Also, with auditors from the Supreme Audit Institutions who audited the Public Prosecution Service of the Republic of Indonesia, and the Corruption Eradication Commission officials to get new views on how the conduct the account administration of confiscated funds.Research findings: The results indicate that there is coercive pressure in making regulations for account administration of confiscated funds in the form of repeated findings from the Supreme Audit Institutions and the Minister of Finance Regulation of 182/PMK.05/2017. Mimetic pressure is also indicated with the requirement to imitate succeeded similar organizations. The General Attorney's Office has to clarify organizational structure for the Evidence and Confiscation Management Section at the District Attorney's level and establish competency standards for all officials. This means less professionalism due to the absence of procedure supported by information system, which becomes normative pressure.Theoretical contribution/Originality: This study contributes to the literature on exploring public sector phenomena in the perspective of three-dimensional Isomorphism of New Institutional Theory; as well as explaining changes in policy and organization structure for the account administration of confiscated funds from criminal cases.Practitioner/Policy implication: This study provides input to reform the account administration of confiscated funds from criminal cases to make it more accountable on its policies and organization structure.Research limitation/Implication: This study only explains and evaluates the weaknesses of account administration of confiscated funds. There is the need of aspects reconstruction based on three-dimensional Isomorphism of DiMaggio Powel’s New Institutional Theory in order to be accountable on its policies and organization structure.

Background: Ectopic pregnancy occurs when a fertilized ovum implants at a site outside the uterine cavity.Methods: A retrospective study was conducted in patients of ectopic pregnancy at a tertiary care centre. All ectopic pregnancies reported during this time period were selected and case sheets were analysed. The risk factors causing the ectopic pregnancies were obtained by clinical history and physical examination mentioned in case sheets. A menstrual practice questionnaire (WHO) was filled telephonically to assess menstrual hygiene practices in our patients of ectopic pregnancy.Results: Risk factors found in our study were age group 21-30 years, multiparity, previous tubal surgeries, low socioeconomic status, past history of PID and poor menstrual hygiene.Conclusions: PID stands out as the most modifiable risk factor. Awareness for the same among adolescents, sexually active females and newlywed couples may prove of paramount importance to reduce the incidence of ectopic pregnancy in long term.
Correlation of endometrial morphology by transvaginal sonography with histopathological examination in patients with abnormal uterine bleeding
Authors: Srinivasan Suguna
Published: September 2022

Background: Abnormal uterine bleeding (AUB) is the most common complaint worldwide. Among Indian women, AUB not only affects the quality of life but also leads to serious consequences such as anemia. prolonged and frequent periods lead to morbidity, diminished quality of life and social embarrassment. Hence this study is undertaken to correlate the endometrial morphology by transvaginal ultrasound with histopathological findings of endometrium in women with AUB.Methods: In this study 173 women suffering from AUB were included. This cross-sectional study was conducted by Transvaginal ultrasound using a 7.5 Mhz Philips Transvaginal sonography (TVS) probe to study endometrial morphology (ET). It is measured at the thickest part in the longitudinal plane and included both endometrial layers. Endometrial sampling and histopathological examination were done.Results: It is observed in our study, AUB is more common among the perimenopausal women (50.9%) and also in multiparous women (86.7%). The commonest problem in our study population is heavy menstrual bleeding (HMB) (45.7%). In our study, the endometrial morphology assessed by TVS correlated statistically with the histopathology of endometrium (p<0.001). Hence, TVS, which is affordable and non–invasive can be used as the first line investigation of AUB, but histopathology of the endometrium always gives the confirmatory result.Conclusions: TVS can be used as the initial investigation for AUB, as it is affordable, non–invasive and has good acceptability by the patients. The endometrial morphology assessed by TVS correlated statistically with histopathological examination.

Authors: Hafiz Aamir , Showkat Showkat A. , Bashir Seerat
Published: September 2022

Background: The parotid gland and the other salivary glands provide a crucial role in the oral cavity by secreting saliva that makes eating, swallowing, speaking, and digesting easier. In order to explore the prevalence of parotid gland tumours by age and gender, clinical modes of presentation, surgical treatments, histological pattern of parotid gland tumours, assess treatment success, and assess consequences, a prospective clinicopathological research was conducted.

Methods: The study was conducted among patients who presented in the outpatient department of ear, nose and throat (ENT) and head and neck surgery (HNS), Government Medical College (GMC), Srinagar with lesions of the salivary glands. The present study was an observational study conducted over a period of 18 months w.e.f. May 2020 up to October 2021.  

Results: A total of 220 subjects were enrolled in the present study. More than half of patients were males. The participants were (33.89±15.7) years old on an average. Males predominated over females among the recruited individuals (59% versus 41%). Sub-mandibular gland lesions were most common in the patients (50.4%), followed by parotid gland lesions (38.6%), minor salivary gland lesions (6%) and sub-lingual gland lesions (5%). Pleomorphic adenoma was the most prevalent neoplastic lesion (29.4%). The most prevalent non-neoplastic lesion was parotitis (21.1%).

Conclusions: More often than malignant tumours, benign parotid tumours are more common. Malignant parotid tumours usually present at a later clinical stage and begin to develop at a younger age than other tumour types. Accurate clinical diagnosis, with the use of fine needle aspiration cytology (FNAC) and imaging as needed, is essential for effective therapy. The primary therapeutic option is a safe operation called a parotidectomy.
Employee Trust and Performance Constraints in Public Sector Organizations
Authors: Vlaicu Razvan , Keefer Philip
Published: September 2022

Theory suggests that employee trust is key to productivity in organizations, but empirical evidence documenting links between trust and constraints on performance is scarce. This paper analyzes self-collected data on public sector employees from eighteen Latin American countries and finds that individual-level trust is relevant to three types of performance factors. First, high-trust employees are more willing to collaborate and share information with coworkers and are more supportive of technological innovation. Second, high-trust respondents have different perceptions of organizational constraints: they are less concerned with low staff quality or lack of discretion to innovate, and more concerned with staff shortages. Third, trust in coworkers is associated with stronger mission motivation. Instrumental variable strategies based on the transmission of trust through social and professional channels account for potential sources of endogeneity. A survey experiment on preferences for social distancing policies provides further evidence that trust enhances mission motivation: employee policy preferences align better with the implied government policy when their trust in the public sector is higher.
Ideas and Values of the "Yellow Vests" Movement in France
Authors: Stepanov Mikhail
Published: September 2022

The "yellow vests" movement that stirred up France in November 2018 was a complete surprise not only for its leaders, but also for the whole world. Spontaneously arising in the depths of social networks from a simple petition for refusing to raise taxes on petroleum products, the horizontal, decentralized association of ordinary citizens has become the largest social protest movement since the student unrest of 1968 and the longest in the history of the Fifth Republic. It made it possible to reveal serious problems in the social organism of the country, about which it was not customary to speak publicly before, and to begin to conduct a comprehensive dialogue on them. It also created a new symbol of the struggle of the grassroots of society for social justice - the yellow vest, which has already acquired an international status. This work is devoted to the study of the ideas and values of the "yellow vests" movement in France. Based on the analysis of a wide range of scientific literature, the results of sociological surveys, statistical data and media materials, an attempt is made to identify and describe the ideas and values of the "yellow vests" movement. Achieving this goal allowed us to get an idea of what motivated people who regularly went to protest rallies in 2018 - 2019. The results of the study can be useful both in the study of modern social protest movements and for conducting a general assessment of the French domestic political situation during the current "five-year plan".
“Crossroads of Memory”: Discussions on the Role of the Slavic Movement during the Second World War
Authors: Boldin Vladimir
Published: September 2022

Modern science is experiencing a real “memorial boom”. Memory studies have become a leading topic in social and humanitarian studies. At the same time, the politicization of the phenomenon of memory is also taking place. Today memory stopped to be the subject of philosophy only. One of the “memory nodes” of modern society is the Second World War. Revisionist tendencies in the interpretation of its causes and consequences are especially strong in the countries of Central and Eastern Europe, which are in the process of constructing their own national identity. Slavic countries are no exception, and memory about the War and the role of the “Slavic movement” in it are becoming very relevant. That is why this article attempts to show the evolution of attitudes towards the Slavic movement and the idea of Slavic unity – from the return of the Slavic theme to historiography, to the political institutionalization of the Slavic movement.

Published: September 2022

A qualidade da arquitetura e do ambiente construído esteve sempre relacionada à saúde pública. Historicamente, com a evolução das técnicas construtivas e de desenho urbano, o ambiente construído foi auxiliando a diminuição de problemas recorrentes, como a cólera. Atualmente, os problemas mais comuns nas sociedades urbanas são outros: o sobrepeso, a obesidade, e outras doenças relacionadas a pouca movimentação física da população.  Sendo a sociedade norte-americana uma das quais tais problemas se manifestam de forma mais aguda, a cidade de Nova Iorque, em parceria com instituições de arquitetura locais, liderou a iniciativa de criar um guia de diretrizes que aplica o conceito active design, ou projeto ativo. O guia dá subsídios para a elaboração de projetos, na escala da edificação e urbana, com a preocupação de gerar um ambiente que estimule a atividade física dos usuários. Analisando-se dados de saúde pública brasileira, há indícios de que o sedentarismo também é responsável, cada vez mais, por doenças que afetam uma parcela significativa da população nacional.  A partir dessa constatação, o objetivo deste trabalho é uma avaliação preliminar do contexto brasileiro atual, averiguando em que nível os projetos de edificações contemporâneas contemplam estratégias de projeto ativo. O método de pesquisa contemplou a estratégia Estudo de Caso. Para tanto foram selecionados projetos de edificações no Brasil, que apresentassem potencialmente  estatégias de desenho ativo. Cada projeto foi analisado segundo os critérios indicados pela publicação de Nova Iorque, Active Design Guidelines. As análises foram sistematizadas utilizando o checklist de estratégias adotadas, proposto pelo material de referência, criando-se um comparativo entre os casos selecionados. Os resultados elencam e evidenciam as estratégias mais comumente aplicadas no cenário da arquitetura brasileira e apontam os principais aspectos neglicenciados.

Published: September 2022

Białka ARGONAUT (AGO) są integralnymi elementami regulatorowych szlaków znajdujących się pod kontrolą małych RNA (ang. small RNA, sRNA), o fundamentalnym znaczeniu dla właściwego funkcjonowania komórek eukariotycznych. AGO, jako wysoce wyspecjalizowane platformy wiążące specyficzne sRNA, koordynują wyciszanie genów poprzez interakcję z innymi czynnikami białkowymi (tworząc tzw. kompleks RISC, ang. RNA-induced silencing complex), przyczyniając się do endonukleolitycznego cięcia docelowego mRNA i/lub wpływając na proces translacji. Coraz więcej dowodów potwierdza również udział białek AGO w kilku innych procesach komórkowych, takich jak np.: regulacja transkrypcji, sekwestracja, zależna od RNA metylacja DNA, naprawa uszkodzeń DNA, synteza siRNA niezależna od białek DCL (ang. DICER-like), czy też kotranskrypcyjna regulacja ekspresji genów MIRNA i splicingu intronów. Poszczególne gatunki roślin charakteryzują się obecnością różnej liczby białek AGO, w wielu przypadkach o nieznanej jeszcze regulatorowej i/lub biologicznej funkcji. Niniejszy artykuł przeglądowy obejmuje aktualną wiedzę na temat funkcji roślinnych AGO w biologii komórki i rozwoju roślin.

Published: September 2022

The application of enzymes in extraction processes within the food industry has not been widely explored. In this paper, an enzyme-assisted water extraction method was employed and optimized to extract the antioxidative and phenolic compounds from the pericarp of Garcinia mangostana L. Fractional factorial design (FFD) was developed to screen out the significant factors from five extraction parameters, including enzyme concentration, liquid-solid ratio, reaction temperature, pH and reaction time. Next, a central composite design approach was used to optimize the significant parameters after the screening process. The optimal conditions according to statistical analysis were 1.46% w/w of enzyme (Celluclast® 1.5L & Pectinex® Ultra SP-L) concentration, 22.80 liquid-solid ratio, reaction temperature of 30 °C, pH 3 and 30 min of reaction time. Under the optimized conditions, antioxidant activities indicated by the 2,2-Diphenyl-2-picrylhydrazyl (DPPH) and 2,2’-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) values and total phenolic content obtained were 86.51%, 86.77% and 21.222 mg gallic acid equivalent (GAE)/g, respectively.
Associated fungal pathogens and causes of postharvest losses in the avocado value chain in Hossana town market, Ethiopia

Published: September 2022

A significant proportion of post-harvest loss of agricultural produce is experienced in Ethiopia, especially in perishable horticultural commodities like fruits (mango, banana, papaya, avocado, sweet orange) and vegetables. Postharvest diseases derived from biotic sources such as microbial pathogens, or physiological disorders caused by abiotic sources contribute to shortening the postharvest life of the avocados, leading to loss in fruit quality. This study aimed to assess post-harvest losses and identify post-harvest pathogens associated with the decay of avocado fruits in Hossana town shops and a market which opens once a week. Random sampling method was used to select shops for survey and sample collection. Avocado fruits with different damage levels and disease symptoms were collected from 14 shops and the Hossana Market, packed using cartons then transported to the laboratory. A survey was conducted in selected shops and the market and identification of disease-causing pathogens was done through incubation of the samples taken from different parts of the fruits using potato dextrose agar (PDA) for seven days. Data was analyzed using SPSS, statistical software. Results from the survey revealed that postharvest loss of avocado varies across different post-harvest handling stages and the highest loss was recorded during storage (40%) followed by harvesting (26.7%). The most mechanical damage was observed in the MS shop (100%) followed by the HM (83.3%). This may be due to poor harvesting practices: unsuitable field or marketing containers and crates, which may have fractured wood, sharp edges, poor nailing or stapling. Disease incidence assessment showed that in three shops (AD2, MN2 and MS), 100% of fruits were infected. The highest disease severity index rated as 5 (>75%) was also observed in the same three shops (AD2, MN2 and MS) and the HM, followed by 3 shops (AD3, GM3 and NR) rated as 4 (51-75%). A total of 82 fungal colony growths were observed with Colletotrichum gloeosporioides being the most frequently isolated species (60 %) followed by Fusarium spp (26.67 %). Appropriate post-harvest handling technology and disease management strategy should be implemented from farm to fork to reduce post-harvest losses.

Post‑crisis Economic Environment of Two Central and Eastern European Regional Centres: A Comparative Approach
Authors: Zsibók Zsuzsanna , Egyed Ildikó
Published: September 2022

Our research studies the economic background of recovery and catching‑up after the global financial and economic crisis, comparing the case study areas of Cluj‑Napoca in Romania and Pécs in Hungary. We use explorative statistical data analysis to describe the post‑crisis regional economic environment in the context of the differential outcomes of the high‑pressure economy in these two countries. Then, we analyse the evolution of the per capita gross domestic product in a decomposed form which provides insights into the main challenges of regional development in the two regional centres. The results show that long‑run economic challenges must be handled with an efficiency‑oriented regional policy that relies upon capital and knowl­edge‑intensive growth.
Using Acemoglu and Robinson’s Concept to Assess Leviathans in CEECs in the Long Term
Authors: Matera Rafał
Published: September 2022

The main objective of the paper is to use the following terms of Daron Acemoglu and James Robinson – Despotic, Real, Paper, Shackled Leviathans – to check and evaluate the state of democracy, governance and social power in Central and Eastern European Countries (CECCs). Six states were included in the study: Poland, Czechia, Slovakia (before 1993 Czechoslovakia), Hungary, Romania and Bulgaria. Based on a historical analysis, Leviathan types were identified in the interwar period, communism, and the transition time. In the most recent period (the twenty‑first century), eight democracy and freedom indices were presented, which take into account the quality of governance, the state of institutions and the potential of social capital in the six CEECs. The usefulness of these indices for assessing whether (and when) a country managed to shackle Leviathan were checked.

Published: September 2022

Member countries of the Organisation of Petroleum Exporting Countries (OPEC) are always in the news regarding the prices and supply of crude oil to the international market. One of the economic reasons for this is liquidity and the desire to accumulate international reserves by the respective countries. This paper examined the determinants of international reserves among the cartel against the backdrop of the motives for keeping reserves. With data from 2005 to 2018, the adopted variables that were tested with the system of generalised methods of moments (Sy‑GMM) are inflation, exchange rates, oil prices, crude oil dependence, economic crises and others. The results and outputs show that inflation was negatively impactful externally and internally, while FDI inflows recorded negative significance. Economic crises and economic openness were positively significant, while oil prices and exchange rates were not significant determinants of international reserves accumulation. The paper recommends the maximisation of opportunities available by members during economic crises to accumulate reserves that will enable them to diversify from dependence on crude oil exports to include other products and a higher level of openness to open the economy up for competition to make the economies stronger.
Cryptocurrency Market and Tax Regulations in Turkey: an Analysis in the European Emerging Economy
Authors: Zengin Burcu , Kocoglu Sahnaz
Published: September 2022

The aim of the article: The purpose of this study is to provide a thorough review of the current state of cryptocurrency market and how governments perceive and deal with the threats and opportunities brought by the block chain technology. Cryptocurrencies were certainly the most popular investment in the last decade with a skyrocketing trading volume. However, cryptocurrency abilities in money laundering, financing terrorism and tax evasion overshadow the great opportunities and potential of this new technology. Therefore, the major economies in the world have been working on an efficient and effective strategy to control and tax the cryptocurrency market. In this study, the current state in Turkey regarding cryptocurrency taxation is analysed and a tax system is proposed. The authors claim that the Tobin tax, or in other words, low tax rates would be the best tax system to be applied in Turkey.

Methodology: The study is based on a detailed literature review on the subject, academic papers, news releases and legal acts of the USA, Europe and Turkey. Different attitudes of varied groups are discussed and proposed solutions in the subject are being considered.

Results of the research: Cryptocurrency market has a great potential and block-chain technology is full of opportunities. However, it is essential to control this market without harming the appeal of cryptocurrencies, yet this is not an easy task. Therefore, we argue that Turkey should extend the usage of cryptocurrencies, create a tax strategy with low tax rates and we claim that a regulation similar to the Tobin tax application would be effective here.

Authors: Abbas Rabia J. , Al-Jrrah Issa A. Thamir
Published: September 2022

Background: This study was conducted to investigate the effects of natural and synthetic sources of lycopene on performance, egg quality and some blood characteristics of Japanese quail layers. Methods: The 252 eight-week-old quail hens were randomly divided into seven treatments with three replication. The first treatment was fed basal diet (control). Second and third treatments were given diets containing tomato fruit powder (TOM) at a level of 17 and 34 g/kg equal to 50 and 100 mg/kg lycopene, fourth and fifth treatments were given red bell pepper fruit powder (RBP) at level 16.23, 32.46 g/kg equal to 50 and 100 mg/kg lycopene, while synthetic lycopene powder at a rate of 50, 100 (mg/kg) was supplemented to sixth and seventh respectively. Result: The final body (T4-T6), hen day egg production (except for T3 and T6), egg weight, egg mass (T4, T5), feed intake, FCR were improved as compared to control. Significant effect on the weight of eggshell, yolk, albumen and albumen (height and diameter). Yolk (height, diameter, index) improved as compared to control. Significant (P≤0.05) increase in total protein and HDL, while cholesterol (except T2 and T7), triglycerides (except T2) and LDL were decreased significantly (P≤0.05). It could be concluded that supplementary TOM, RBP and LY, have beneficial effects on laying performance, egg quality traits and some biochemical indices of quails.

Background: Artificial insemination with chilled sperm is a reproductive biotechnology often used in horse breeding. However, maintaining the acceptable sperm quality after cooling, which affects the frequency of pregnancy, remains an urgent problem at the present time. Therefore, clarifying the role of important physiological metabolites, such as L-carnitine and nitric oxide, is a significant aspect in terms of possible improvement of the quality of cryopreserved sperm. Methods: The study included 35 breeding stallions, 27 of which were stallions of the Arabian breed and 8 were of the Soviet heavy draft breed. The content of total, free and bound carnitine and NO metabolites was determined by photometric method in the samples of seminal plasma and blood plasma. The correlation coefficient between the content of L-carnitine and the level of NO metabolites was also determined. Result: We have found a direct moderate correlation between the level of total and free L-carnitine in the seminal plasma and blood plasma. The study has also revealed a positive correlation between the level of all L-carnitine fractions and NO metabolites in seminal plasma. In addition, there was a positive correlation between the total L-carnitine of blood plasma and NO metabolites in seminal plasma.
