Abstract

Introduction
Feline panleukopenia is a contagious viral disease caused by the feline panleukopenia virus (FPV). A closely related pathogen is canine parvovirus (CPV), and amino acid substitutions in this virus allow it to acquire a feline host range. In feline hosts, the disease induced by CPV manifests with similar symptoms to those caused by FPV or milder ones, leading to its underdiagnosis. The aim of this study was to determine the presence of CPV type 2 (CPV-2) in cats with clinical symptoms of panleukopenia and to assess the use of commercial CPV antigen tests for the clinical diagnosis of FPV.

Material and Methods
Samples from 59 cats from central Slovakia were included in the study. Rectal swabs were collected and clinically tested for parvovirus infection using a commercial antigen test. Antigen-positive samples were confirmed by PCR targeting the viral VP2 gene. The sequences of the PCR products were established with the Sanger method.

Results
Of 59 samples, 23 were revealed to be positive for parvovirus infection by both antigen and PCR test (38.9%). Analysis with the National Center for Biotechnology Information BLASTn application showed 99.78–100% pairwise identity with FPV. The mortality rate of parvovirus-infected cats included in this study was 8.69% (2/23).

Conclusion
Although feline disease with CPV-2 was not confirmed, the CPV antigen test was able to detect FPV infection.

Objective: This research aimed to compare two methods for determining soil organic carbon, in two soils with different textures.

Method: Soil samples were collected in three locations (Dourados-MS, Chapadão do Sul-MS and Cassilândia-MS), with different textures (clayey and sandy), at a depth of 0-20 cm, to determine organic carbon . The results were subjected to statistical analysis, using the SAS version 6 software and the means were compared using the t test (p < 0.05). In the correlation study, linear regression analyzes were performed.

Result and conclusion: There was variation in the soil organic carbon content (SOC) between the methods studied for both soils. Measuring soil samples by volume (spectrophotometer) modifies the results, regardless of the soil texture. There is greater variation between the data obtained in soils with a higher COS content than in soils where the COS content is lower. Furthermore, the results indicate the need for new studies in which soils from agricultural areas and under native vegetation are selected by soil classes, textures and types of land use.

Research implications: Research related to comparison studies of SOC determination methods is of paramount importance, as there is a lack of information regarding the definition and recommendation of the most appropriate method.

Originality/value: With this study it is possible to disseminate to the scientific community methods for determining SOC that make it possible at the same time to reduce the use of chemical reagents, without this negatively interfering with the quality of soil organic carbon determination.
The Impact of a Common Currency on the European Union
Authors: Abraham Mensah  , Ayooluwa Tomiwa Animashaun  
Published: April 2024

This study examines the ramifications of adopting a common currency within the European Union (EU), focusing on introducing the euro. Initially prompted by optimistic expectations of economic stimulation and balanced budgets, the research critically assesses the economic, trade, and policy dimensions associated with a unified currency. Utilizing Mundell's optimal currency regions concept, the methodology establishes prerequisites for a successful monetary union, emphasizing vulnerability to macroeconomic shocks, labor market flexibility, and intra-regional commerce. Findings reveal that while a common currency eliminates foreign exchange expenses, reduces uncertainty in bilateral exchange rates, and facilitates investments, member states must sacrifice autonomy in monetary and exchange rate policies. The advantages include streamlined cross-border payments, enhanced trade, and improved movement of labor and products, while the drawbacks involve rigid monetary policies and limitations on policy tailoring to specific economic conditions.
To maximize benefits, the research proposes measures such as deepening economic integration, ensuring macroeconomic stability, and promoting political unity. The study emphasizes the importance of sound economic policies to complement the adoption of a common currency and mitigate potential challenges. In conclusion, the research offers a comprehensive understanding of the advantages and disadvantages associated with a common currency in the EU, providing a roadmap for effective navigation and suggesting interventions to ensure successful implementation.
Public Financial Management (PFM) Laws and Audit Quality in Ghana: The Moderating Role of Auditor-Client Relationship
Authors: Amofa-Sarpong, Kwabena  , Dr. Tornyeva Kingsley  
Published: April 2024

Purpose: This study examines the extent to which public financial management (PFM) laws contribute to audit quality in the public sector and how the auditor-client relationship moderates this effect.
Design/Methodology/Approach: This study used a quantitative survey research design to collect data from about 400 public sector auditors working with Ghana's Supreme Audit Institution (SAI), the Audit Service, by adopting the contextual factor of the IAASB's framework for Audit Quality using the PLS-SEM method of analysis.
Findings: The study found that in the Public Sector, Public Financial Management (PFM) laws positively influence audit quality, while auditor-client relationships also negatively contribute to audit quality.
Furthermore, it was also established that the auditor-client relationship negatively moderated the relationship between Public Financial Management (PFM) laws and audit quality.
Implications/Research Limitation: The results of this study extend and add to the growing empirical studies on Public Financial Management (PFM), audit quality and the field of public sector auditing. However, the study will be limited to only public sector auditors working with Ghana's Supreme Audit Institution (SAI), the Audit Service.
Practical Implication: The study results have the prospect of encouraging policy-makers to strengthen the independence and improve the capacity of the State Auditor (i.e. Ghana Audit Service) through appropriate PFM laws that seek to improve auditor-client relationships through relevant compliance and enforcement mechanisms.
Originality/Value: This study is the first to directly examine how the Public Financial Management (PFM) laws contribute to audit quality in Ghana and how the auditor-client relationship moderates this effect.
Nevertheless, this study differs from other prior empirical research on the basis of the method employed and the context of the study.
Remittances, Debt Service Payments and Economic Growth in Nigeria
Authors: Yussuff, Rukayat Omobolanle  , Israel Emmanuel  
Published: April 2024

The study investigates the intricate relationship between the effects of remittances (REMIT) and debt service payments (DSP) on economic growth (RGDP) as well as other key variables, external reserve (ER), foreign direct investment (FDI), and external debt (EXTD) on economic growth (RGDP) in Nigeria from 1995 to 2021. Various statistical techniques, such as Ordinary Least Square (OLS), Augmented Dickey Fuller (ADF) tests and ARDL, were used. The result indicates the existence of a positive correlation between RGDP and FDI; DSP and ER exhibit a moderate negative correlation, while REMIT and DSP show a strong negative correlation. ER and REMIT indicate a correlation, while EXTD and ER indicate a negative correlation. All variables are I(1) and the ARDL Bound test for co-integration indicates that a long-run relationship exists between dependent and independent variables. ARDL estimation shows that only the coefficient of external debt is significant. The R2 shows that 84% of the variation in RGDP is explained by the independent variables. The test for autocorrelation (DW = 2.33) indicates no autocorrelation in the error term.
This study recommends that policymakers should implement measures to attract and retain foreign investments, given the positive impact of FDI on RGDP, and Policymakers should explore strategies to channel remittances into productive sectors, such as investments in infrastructure, education, and small-scale enterprises.

This third article examines such genres of cinema as war films, detectives and comedies the latest in the line of Arctic films. Thereby we draw a line under Arctic films, that have not received due attention from film critics and the public until now. The need to return to the past to take a fresh look at the solar, including its storyboard, taking into account the deep rethinking of the war and the direct depiction of what was experienced, to show a truthful and accurate image of the war on the example of the fate of one or many of its participants. Cinematographers constantly return to the theme of the war, its individual episodes, the people who took part in it, who noted their heroism in it, its new reading caused by changing socio-political views and access to previously censored circumstances, what is now called «trench truth».«Another war» in pleacetime was reflected in the Arctic detectives. The enemy appears in them as criminal elements, sometimes was sophisticated and insidious plans, which in the conditions of the north require a special approach to solve then. Comedies have no geographical boundaries. Humor and laughter in the snow and ice is special, very often associated with the behavior of animals, especially dogs.

Published: April 2024

Needless to say that telecommunications’ operators are showing increasing interests toward solving the dilemma of optimizing network resources while offering state-of-the-art quality of service. Recently, operators have shown an increasing interest to investigate solutions for better control on network utilization, service usage and monetization. They also noticed a significant growth in Diameter signaling and more specifically in signaling related to policy management. A massive introduction of Voice over LTE (VoLTE) service will have a significant impact on the systems handling policy signaling, as VoLTE will reshape the landscape of Long Term Evolution (LTE) policies and completely change the way policy management works. However, this massive approach is meant to provide significant competitive advantages for operators offering LTE services and still require circuit-switched network to provide voice service. The biggest challenge for those operators is to find an appropriate solution, scalable enough to handle the unpredictable growth of Diameter signaling. In this paper, a model, based on Network Function Virtualization (NFV) technology is proposed, able to address the challenges of massively introducing VoLTE, without impacting existing services and without jeopardizing current revenues. In presented approach, the standard VoLTE call flows, referenced user’s behavior and latest experiments’ results on NFV technology are used.

ASSESSMENT OF BOTTOM SEDIMENT POLLUTION IN SMALL RIVERS, VLADIMIR REGION
Authors: Chesnokova S. M. , Savel’ev O. V. 
Published: April 2024

The results of assessing pollution of bottom sediments in four small rivers of the Vladimir region with heavy metals (HM) and phosphates are presented. According to HM concentration coefficients characterizing the concentration (anomaly) of elements in bottom sediments in respect to their background content in the region, the zones of technogenic multi-element geochemical anomalies in the channels of all studied watercourses and their structure were identified. It has been established that Fe, Pb, Co, Cu, Zn, Cr, and Mn are the priority metals of technogenic geochemical anomalies in bottom sediments. The highest pollution of bottom sediments with these metals is typical for the zones influenced by the runoff from the territories of collective orchards, livestock complexes, large industrial cities and rural settlements. According to the total pollution indicator (Zc), which reflects the additive excess of the background content of a group of heavy metals that are part of technogenic geochemical anomalies, the studied watercourses are located in the following order: Sodyshka Kamenka Rpen Ilevna, and according to the phosphate content: Sodyshka Rpen Kamenka Ilevna. Correlations between the components of bottom sediments have been studied. The average load of heavy metals and phosphates on watercourses was assessed.
DRIFTING TIMBER FORMATION ON MUDFLOW RIVERS ON SAKHALIN ISLAND
Authors: Rybalchenko S. V. 
Published: April 2024

The paper considers the regional features of the phenomena of timber drifting on mudflow rivers on Sakhalin Island. The regularities of mudflow formation in Sakhalin rivers and their mudflow regime are established and the factors causing timber drifting in the debris flow watercourses of Sakhalin Island are studied. Due to the history of Sakhalin terrain and macrorelief formation, the main mountain structures are composed of marine sediments. This promotes mudflows on rivers, the active development of exogenous processes on river slopes, and the flow of solid phase and woody vegetation into the channel and talvegs. As a result, the density of streams increases, their eroding and abrasive ability rises, which affects significantly channel deformations and involves timber drifting. High-density flows have an elevated transporting capacity, since they increase the pulling force of the flow affecting the midsection of the drifting timber root system, and also raise the timber buoyancy due to an increase in the pushing Archimedean force. Also, regional features include a large amount of liquid precipitation, the annual amounts of which in the valleys and on the coast are 800–1200 mm, and in mountainous areas can reach 1500–2000 mm. The main species of drifting timber drifting include broad-leaved trees (willow and alder), which, unlike coniferous wood, are more prone to form logjams and are most hazardous for culverts.

Authors: Yuganova T. I. , Putilina V. S. 
Published: April 2024

Incineration is a common method for treating municipal solid waste, which reduces its mass by 70% and volume by up to 90%. However, most of the non-combustible components are subsequently concentrated in a relatively small amount of incineration residues – bottom ash and fly ash – which must be further processed and / or landfilled. The article describes the formation and composition of incineration residues, issues of recycling and environmental regulation, leaching of pollutants and the problems of its testing, methods of treating incineration residues to reduce environmental impact.
FUNCTIONAL DIVERSIFICATION OF THE CAROTENOID-<i>CIS-TRANS</i>-ISOMERASES CrtISO, CrtISO-L1, AND CrtISO-L2 IN TOMATO SPECIES (<i>SOLANUM</i>, SECTION LYCOPERSICON)
Authors: Efremov G. I. , Shchennikova A. V. , Kochieva E. Z. 
Published: April 2024

The expression of the genes of carotenoid-cis-trans isomerases CrtISO, CrtISO-L1 and CrtISO-L2 was studied in comparison with the content of carotenoids in tomato species with different ripe fruit colors: green (Solanum habrochaites), yellow (S. cheesmaniae) and red (S. pimpinellifolium and S. lycopersicum). More ancient origin of CrtISO-L2 was shown in relation to CrtISO and CrtISO-L1. A similar content of total carotenoids (leaves) and β-carotene (ripe fruits) was found between the samples. Unlike fruits of S. habrochaites and S. cheesmaniae, red fruits accumulated lycopene and 20-30 times more total carotenoids. The highest level of transcripts both in leaves and in ripe fruits was detected for CrtISO. The CrtISO-L1 and CrtISO-L2 were transcribed high in leaves and low in fruits, except for the high expression of CrtISO-L2 in S. lycopersicum fruits. No relationship was observed between the content of carotenoids and the level of gene expression in the fruit. In the leaves, a positive correlation between the amount of carotenoids and the levels of CrtISO-L1 and CrtISO-L2 transcripts was found.

The results of a geochronological study (U–Pb SHRIMP-II) of zircon from granodiorites and plagiogranites of the main phase of the Tallain pluton of the Baikal-Vitim belt are presented. The obtained estimates of the age of the magmatic cores of zircon from granodiorite and plagiogranite coincide with each other within errors and are interpreted as the age of crystallization of rocks of the main phase of the Tallain pluton 661 ± ± 6 million years. The weighted average age of the metamorphic zircon shells of these rocks is 637 ± 5 million years. High positive values of ɛNd (660) +7.2 and +7.3 in the rocks of the main phase indicate a juvenile source of the parent melts. Based on new and previously published geochronological data, a conclusion is made about the formation of similar late Neoproterozoic juvenile gabbro-granite associations of the Baikal-Vitim belt at the turn of 660 million years (Tallain complex) and 603–615 million years (Padorinsky complex).

The age relationships between the alkaline rocks from the region of the rare-metal (Y, REE, Nb, Ta) Aryskan deposit have been determined. Metamict zircon with high content of U, Th was used as a geochronometer. A dedicated treatment protocol was used for sample preparation for geochronological U–Pb (ID TIMS) studies. Dating of zircon from alkaline granites of the Aryskan and nearby Astyg massifs showed that their formation occurred almost simultaneously, 448 ± 1 and 446 ± 1 million years ago, respectively. The supposed genetic relationship of alkaline granites with the accomodating alkaline-feldspar syenites formed 472 ± 2 million years ago (zircon, U–Pb, ID TIMS), has not been confirmed.

U–Th–Pb LA-ICP-MS was used for dating detrital zircons extracted from the cement of the Neoarchean and Palaeoproterozoic polymictic conglomerates of the Karelian province, Fennoscandian shield. For the first time obtained a chemical composition of terrigenic and volcanogenic rocks of the gimolskaya formation. Obtained data showed that the detrital zircons from the cement of conglomerates of different ages yield similar results of about 2750 Ma. In the Neoarchean conglomerates of the Sukkosero area dominate clasts of the gneissic tonalite and plagioporphyry. They are identical in chemical composition with the Neoarchean (2.78–2.73 Ga) TTG, granodiorite, and metadacite of the Central-Karelian domain. The feature of these rocks is increased content of Ba (900–1200 ppm), Sr (600–700 ppm), and ratios Sr/Y = 34–90, (La/Yb)n = = 17–30. The chemical composition of the cement (the values of CIA 55 and the negative values of the function DF(x)) is similar to the composition of clasts, which means cement is composed of finer clasts of the same rocks. The Paleoproterozoic conglomerates of the Vottomuks area contain zircon from felsic rocks of the Neoarchean basement/ The chemical composition of the cement of the Paleoproterozoic conglomerates and the predominance of basaltic andesites of sumii is evidence of the post-sumii (2.45 Ga) age of these rocks. The absence of the Paleoproterozoic zircon in cement can be the result of the absence of it in the Paleoproterozoic source rocks. The age of Neoarchean conglomerates from the gimolskaya formation is less than 2.75 Ga.

Authors: Guseva A. S. , Petrov V. A. 
Published: April 2024

Since 2012 the territory of Moscow has increased by 2 times, the Troitsky and Novomoskovsky administrative districts (TiNAO) were annexed to Moscow. Due to the fact that earlier this territory was part of the Moscow region, detailed studies of the ecological state of soils were not carried out. In the period from 2019 to 2020 years to assess the soil pollution with heavy metals of certain areas of New Moscow, both in forest areas and near man-made objects that are potential sources of pollution, samples were taken up to 10 cm deep and analyzed by X-ray fluorescence analysis for the content of V, Ni, Pb, Cu, Zn. It was revealed that at present the surveyed areas are characterized by an acceptable level of pollution, exceeding the maximum permissible concentrations was not detected. It is shown that anthropogenic activity contributes to technogenic soil pollution. It is recommended to conduct annual environmental monitoring for the purpose of early detection of pollution foci.
