Physical activity induces oxidative stress which causes fatigue which can be acute or chronic in athletes, responsible for a reduction in physical performance. The objective of the study was to evaluate the antioxidant activity of the aqueous extract of Cymbopogon citratus and its effects on the lipid profile in albino rats of the Wistar strain subjected to forced swimming.   Twenty (25) male rats were fed a standard laboratory ration and divided into 5 batches of 5 rats, then subjected to a 14-day treatment with distilled water, 100 mg/kg, 200 mg/kg or 400 mg/kg of extract and swam every 2 days. On the 14th day, the rats except the control groups were subjected to the forced swimming test with a load of 10% of body weight attached to the tail. The results showed that Cymbopogon citratus reduces the DPPH radical and prevents tissue lipid peroxidation, dose dependent by decreasing Malondialdehyde level (p ˂ 0.001) in liver, lung and gastrocnemius muscle, increases dose dependent cellular concentrations of reduced Glutathione in liver (p ˂ 0.05) and studentthe specific activity of Superoxide dismutase in the lungs (p < 0.001). C. citratus reduced serum levels of total cholesterol (p ˂ 0.05) and LDL-cholesterol (p ˂ 0.01).  C.citratus fights against oxidative stress induced by physical activity in rats. It would be interesting to test its action on other rat strains and endurance models.

Published: January 2025

A neurodegenerative illness characterised by chronic inflammation and demyelinating symptoms, multiple sclerosis (MS) mostly affects young people's central nervous systems. The condition is complex and variable due to multiple environmental and genetic factors. A disorder mediated by the immune system is what it is. Symptoms of neurological dysfunction that last a few days or weeks and can be recovered are common in the early stages of the disease, which include clinically isolated syndrome and relapsing-remitting multiple sclerosis. Turmeric, whose scientific name is Curcuma longa Linn. (C. longa), is a member of the Zingiberaceae family of plants that has a rich history of use in traditional medicine. In Unani and Ayurvedic medicine, C. longa has been used topically for inflammation and ulcers, and internally for jaundice and liver blockage. Blood purification, asthma, haemorrhoids, bronchitis, tumours, wounds, indigestion, colds, dental problems, skin infections, and hepatic illnesses are all helped by its antiseptic properties. The crucial phase that starts this cascade is when Th17 enters the central nervous system (CNS) through the blood-brain barrier (BBB) through damaged tight junctions. Interleukin (IL)-17 and IL-22 attach to their BBB receptors, allowing the migration to proceed. Then symptoms of neuromuscular diseases, such as axonal degeneration, start to show themselves. The Zingiberaceae family plant Curcuma longa is the source of curcumin, the active ingredient in turmeric. There is hope for the treatment of multiple sclerosis (MS) thanks to recent findings about the properties of curcumin, namely its ability to suppress the release of proinflammatory cytokines. When it comes to treating MS, this study will look at curcumin's many features and major impacts.

Published: January 2025

The D-optimal mix design was utilized in the new product development process of the Moringa oleifera effervescent tablet to optimize the acid-base ratio in the recipe. The antioxidant activity and chemical profile of the Moringa oleifera extract were assessed. Measurements were made on the physicochemical and sensory properties of the effervescent Moringa oleifera tablet. Because moringa leaves, which are a component of the Moringa Oleifera plant, have a high antioxidant content, they help the body fight off free radicals. Additionally, the contents of the leaves may be turned into effervescent granules, a functional drink. The kind and proportion of the effervescent agent have a significant impact on the granule's physical properties, stability, and acceptability. Because they both offer a texture and mouthfeel that is acceptable, sodium bicarbonate and citric acid were employed as the effervescent agents in this investigation. Three formulations (designated as F1, F2, and F3) with varying ratios of citric acid to sodium bicarbonate were chosen. The wet granulation process was used to create these formulations. The three formulations' effervescent granules demonstrated good particle size distribution and flow capabilities. Furthermore, an extract from Moringa oleifera displayed IC50 values of 320µg/ml. Acceptability-wise, all of the recipes had a somewhat bitter taste, which could be attributed to the extract's tannins and phenolic components. Addition of flavoring agents, such as lemon and strawberry, is unable to mask the bitter taste of the final tablet. Here in, the first Moringa leaves effervescent tablet prepared using wet granulation was successfully formulated.
Creutzfeldt-Jakob Disease (CJD): A Deadly Neurodegenerative Condition; Its Epidemiology, Monitoring, Current Status of Prevention and Circumvention
Authors: Yash Srivastav  , Abdul Hameed
Published: January 2025

Creutzfeldt-Jakob Disease CJDis a rare brain ailment that causes dementia. It is often referred to as Creutzfeldt-Jakob. It is a member of a class of illnesses called prion disorders that affect both humans and animals. Alzheimer's disease and Creutzfeldt-Jakob disease symptoms can be comparable.A rare yet deadly neurodegenerative condition is Creutzfeldt-Jakob disease (CJD). According to reports, it affects one in one to one and a half million people worldwide each year, with less than 1,000 cases occurring in the US.A deadly neurodegenerative condition, Creutzfeldt-Jakob disease (CJD) is also referred to as subacute spongiform encephalopathy or neurocognitive dysfunction caused by prion disease. Memory issues, behavioural changes, poor coordination, and visual impairments are some of the early indications. Dementia, uncontrollable movements, blindness, paralysis, and coma are later signs. Within a year, almost 70% of people pass away.In 1922, Walther Spielmeyer coined the term "Creutzfeldt–Jakob disease" in honour of the German neurologists Hans Gerhard Creutzfeldt and Alfons Maria Jakob. A protein called a prion folds abnormally to cause CJD. Misfolded proteins known as infectious prions can cause other misfolded proteins to do the same.People with CJD experience a variety of symptoms, such as uncontrollable muscle spasms or mobility issues, memory loss, and cognitive challenges. Because CJD causes so much damage, it is ultimately fatal.The diseases CJD and variant CJD (vCJD) are not the same, despite their very similar names. They're both prion illnesses. But eating meat from cows with bovine spongiform encephalopathy, also known as Mad Cow Disease, is linked to variant CJD. CJD mostly happens seldom and is sometimes referred to as "classic CJD" to prevent confusion.Although there isn't a known cure for Creutzfeldt-Jakob disease (CJD), the National Prion Clinic is doing clinical research to look at potential therapies. Currently, the goal of treatment is to keep the patient as comfortable as possible while using medications to lessen symptoms.The present state of Creutzfeldt-Jakob disease (CJD), its underlying causes, and possible treatments are assessed in this article.

Authors: Nandini . , Dash Smruti Swagatika , Kachhwaha Rajendra
Published: January 2025

Background: Frozen shoulder is a condition that is characterized by pain, decrease in range of motion, stiffness in shoulder joint. It also leads to restriction of daily living activities. Frozen shoulder is reported to affect 2% to 5% of the general population. It affects mostly age group of 30 to 60 years. In frozen shoulder, capsule become hard, thick and tight and there is loss of axillary pouch and joint volume which leads to lack of motion of shoulder joint. Shoulder capsule get thick with mild chronic inflammation and fibrosis along with infiltrate.
Recent advancements in physiotherapy, including techniques like movement with mobilization, matrix rhythm therapy, sleeper's stretch, gongs mobilization, and myofascial release, show promise in improving outcomes. However, there is a lack of comprehensive research comparing the effectiveness of these modern physiotherapy approaches. This study aims to address this gap by evaluating and identifying the most effective treatments for managing frozen shoulder, thereby enhancing clinical practice and patient outcomes.
Conclusion: This study concluded that matrix rhythm therapy, Gong’s mobilization and MWM techniques showed significant improvement in reducing pain, improving ROM and shoulder functions among patients with frozen shoulder.

Recent Advances in Physiotherapy Treatment Techniques for Plantar fasciitis- A Narrative Review
Authors: Sharanya Kamisetty Vishnu Sai , Dash Smruti Swagatika , Kachhwaha Rajendra
Published: January 2025

Background: Plantar fasciitis (PF) is a common musculoskeletal disorder primarily characterized by degeneration rather than inflammation of the heel's plantar fascia, causing localized pain. It affects approximately one in ten individuals during their lifetime, with factors such as reduced ankle dorsiflexion angle and calf muscle stiffness contributing to its development. PF typically presents with severe pain upon initial weight-bearing after rest, improving with movement throughout the day. Diagnosis involves tenderness at the medial calcaneal tubercle and pain upon passive dorsiflexion of the first toe.
Despite its high prevalence, effective and early diagnosis of PF remained challenging. A better understanding of its underlying mechanisms, such as the role of calf muscle stiffness and ankle dorsiflexion limitations, was needed to improve prevention and treatment strategies. Additionally, research into the long-term outcomes of various treatments for PF, particularly conservative methods versus more invasive interventions, was crucial to guide evidence-based clinical practice
Conclusion: Extracorporeal shockwave therapy, Tapping, Local vibration, stretching exercises and Dry needling with electrotherapy shows significant improvement in reducing pain, improving ROM and foot functions among patients with plantar fasciitis.

Authors: Akpan Mfon
Published: January 2025

This study investigates the correlation between the number of views and non-fungible tokens (NFTs) valuation, explicitly focusing on Sandbox land assets. This study uses data from the OpenSea marketplace to examine various valuation metrics, including current price, offer price, and floor price. It develops a digital investment valuation and analysis (DIVA) model to predict NFT valuations. This study employs a quantitative research design, incorporating descriptive statistics, correlation analysis, and multiple regression analysis to analyze the data. The findings reveal significant positive correlations between views, offers, and current prices, highlighting the critical role of attention in NFT valuation (Wang et al., 2021). The validated DIVA model demonstrates strong predictive power, explaining 75 percent of the variance in current prices. These insights are crucial for investors, creators, and platform operators, emphasizing the importance of visibility and engagement in maximizing NFT values (Sun, 2024). This study aims to contribute to the literature on digital asset valuation and offers insights that may inform investment strategies and market efficiency in the evolving NFT market. Future research should consider more extensive and diverse samples and explore additional variables to refine the valuation model.

Published: January 2025

Introduction: against the background of the ongoing incidence of coronavirus infection, the selection of therapy often requires individual approaches, especially in comorbid patients. Despite the emergence of specific prevention methods and new antiviral drugs, there are risk groups for severe disease and high mortality.

Target. To evaluate the effectiveness and safety of the use of SARS­CoV­2 neutralizing antibodies for the treatment of comorbid patients with coronavirus infection.

Materials and methods: A retrospective study was conducted to evaluate the clinical efficacy of virus­neutralizing antibodies for the treatment of comorbid patients with coronavirus infection who were hospitalized in 2022. A total of 244 patient records (mean age 60.0±14.2 years) with confirmed SARS­CoV­2 coronavirus infection were analyzed. The first group consisted of patients who received monoclonal virusneutralizing antibodies (monotherapy with Sotrovimab or Regdanvimab, combination therapy with Casirivimab and Imdevimab, or Bamlanivimab and Etesevimab), and the second group consisted of patients without therapy. All patients were comorbid. The most frequently observed nosologies were: hypertension (74.1%), chronic kidney disease (55.2%), malignant neoplasms (31%), 1–3 degree of obesity (22.4%), diabetes mellitus (17.2%), and autoimmune diseases (17.2%). In the comparison groups, the duration of the disease, the area of lung tissue damage, the duration of respiratory support, the percentage of complications, the need to use immunosuppressive therapy, as well as the percentage of fatal outcomes, were assessed.

Results: The duration of the disease in patients who received monoclonal virus­neutralizing antibodies was 16.0±8.1 days, the area of lung tissue damage was on average 14.9±13.0%, the duration of respiratory support was 2.2±3.1 days, complications of coronavirus infection were noted in 31%, the mortality rate decreased to 1.7%. In patients without therapy with these drugs, complications of the disease were detected 2 times more often – in 64% of cases, the duration of the disease was 20.0±6.1 days, the area of lung tissue damage was on average 21.7±12.1%, and the duration of respiratory support was 8.0±6.1 days. Immunosuppressive therapy was used significantly more often in patients without therapy with antiviral monoclonal antibodies (51.2%) than with it (3.4%). A study of the clinical efficacy of various monoclonal antibodies showed an advantage in using Regdanvimab in comorbid patients, as indicated by the absence of fatal outcomes and a reduction in the duration of the disease to 9.8±4.8 days.

Conclusions: Preparations of synthetic recombinant monoclonal neutralizing antibodies to SARS­CoV­2, provided that they are used in the early stages of the disease, significantly reduce the severity of coronavirus infection, the development of complications and significantly reduce mortality in comorbid patients.

Trade value prediction (TVP) is major for understanding financial dynamics
and directing policy decisions in the perspective of complex systems
science. The study emphases on an analytical model intended to predict
future trade values by evaluating financial indicators, past trade data,
and geopolitical powers. By using advanced statistical models and machine
learning techniques, the model explores relationships and patterns in trade
flows among countries. The perceptions increased from this technique offer
beneficial support for policymakers and businesses, guiding them to
forecast the effects of financial and policy changes on global trade. Also,
the study emphasizes the importance of a complicated method to enhance the
accuracy of trade predictions and aid tactical decision-making in a
worldwide interconnected economy. This study proposes trade value
prediction using hybrid graph convolutional recurrent neural network with
Lion optimizer algorithm (TVP-HGCRNNLOA) methodology. The objective function
of the TVP-HGCRNNLOA methodology is to develop an accurate predictive model
for trade values between countries. Primarily, the TVP-HGCRNNLOA approach
undergoes the data normalization by employing linear scaling normalization
technique. Then, the hybrid graph convolutional recurrent neural network
(HGCRNN) method is used for forecasting process. At last, the TVP-HGCRNNLOA
model performs the hyperparameter tuning by utilizing the Lion optimization
algorithm model. The experimental analysis of the TVP-HGCRNNLOA methodology
is investigated in terms of various measures under mean squared error, mean
absolute error, and mean absolute percentage error. The performance
validation portrayed the superior performance of the TVP-HGCRNNLOA
methodology over other existing approaches.

Pheochromocytoma: Therapeutic Agents against the Disease and Chromatographic Methods for their Determination in Biological Fluids
Authors: CJ Mbah
Published: January 2025

Pheochromocytoma is a neuroendocrine tumour of the adrenal medulla and manifests itself by sustained or paroxysmal
hypertension due to excessive production of catecholamine’s. The symptoms require medical diagnosis and because of
hormones secreted such symptoms may include high blood pressure, headache, rapid heartbeat, and sweating. Biochemical
tests to confirm elevated levels of metanephrine and normetanephrine (catecholamine metabolites), imaging studies (magnetic
resonance imaging, computed tomography, scintigraphy) are generally used to diagnose the disease and its metastases. The
purpose of the study was to summarize therapeutic agents used to treat pheochromocytoma and provide some of the liquid
chromatographic analytical methods utilized to determine the therapeutic agents in biological fluids. The methodology
involved literature review covering the title of the study. It was carried out by utilizing library scientific journals; scientific
online databases such as Drug Bank, Embase, International Pharmaceutical Abstracts, Medline, PubChem, PubMed, Science
Direct, and Scopus. These databases provided the required information. Results obtained revealed that treatment of the
disease involved surgical removal of the tumour (gold-standard treatment), radiotherapy and chemotherapy (catecholamine
blockade). Several analytical methods namely chromatographic, electrochemical, spectroscopic methods have been described
to measure these therapeutic agents used to treat pheochromocytoma in biological fluids. In conclusion, treatment of
pheochromocytoma involves therapeutic agents such as alpha1 (α1) adrenoceptor antagonists, beta (β)-adrenoceptor
antagonists, calcium channel blockers, and anti-neoplastic agents. Amongst the chromatographic methods, hyphenated liquid
chromatographic methods are of the most interest to analytical scientists.
Analysis of Protein Metabolism by Biochemical Parameters in Holstein Cows for Preventing the Reproductive System Pathologies
Authors: Novak M. D. , Novak A. I.
Published: January 2025

Introduction. Protein metabolism disorder (dysproteinemia) in dry and freshly calved cows often becomes a complicating factor during mastitis and endometritis and leads to the animal's liveweight decrease. Timely detection of physiological disorders and diseases in the highly productive animals by means of a biochemical blood test is the basic method to preserve the optimal indicators of herd productivity and prevent the economic losses, however, this issue is insufficiently followed up in the dairy farms. The aim of the present research is to analyse the protein metabolism in highly productive Holstein cows by biochemical parameters for timely prevention of the dysproteinemia and pathologies of the reproductive system.

Materials and Methods. The research was carried out in the conditions of a large dairy farm in the Central district of the Russian Federation in the period from March to June 2019. The objects of the research were 45 highly productive Holstein cows (dry, freshly calved and milking cows — 15 heads in each group). To analyse the protein metabolism and inflammatory processes in the tissues and organs of dry and freshly calved cows, the following biochemical blood parameters were studied: total protein, albumin, globulin, urea, creatinine, uric acid, transferase enzymes — ASAT and ALAT. The analysis was carried out by comparing the results obtained with the normal values of physiological parameters.

Results. In 5 out of 15 dry cows, the albumin level was 5.3–16% lower, and in freshly calved cows it corresponded to the lower limit of the physiological norm values. The total protein in the blood of the freshly calved cows was lower than normal by 20–23%, on average. The concentration of urea in blood of all cows under research was reduced by 1.5– 2.5 times, creatinine was 2–2.5 times elevated (56–89%). The ASAT enzyme activity in 75% of dry and in all freshly calved cows was 2–4 times higher. The reserve alkalinity parameter was 0,6–2,4 times less than the physiological norm values in all animals under research.

Discussion and Conclusion. During the research it was found that the compliance of the protein level in the diet of productive animals with the biological needs of their organisms should be determined by the concentration of total protein and albumin in the blood serum, and dysproteinemia and various pathologies of the reproductive system — by the content of urea, creatinine and activity of the aspartate aminotransferase (ASAT) enzyme.

Comparison of EPM with Rusle for soil erosion modeling in the Strumica river basin
Authors: Trendafilov Bozhin , Minchev Ivan , Trendafilov Aleksandar , Blinkov Ivan
Published: January 2025

The most recent climate change scenarios indicate an increase in extreme climate events (rainfall) and therefore an increase in soil loss. Strumica River is a tributary of river Struma/Strimon – a transboundary basin in North Macedonia (Strumica), Bulgaria and Greece that flows to the Aegean Sea. Most of the models incorporated in several software packages, use the USLE (Universal Soil Loss Equation). USLE-based models (RUSLE, MUSLE) are designed to model soil loss on gentler slopes and in agricultural areas. Furthermore, the model considers soil removal, but not the mass movement processes. On the other hand, the EPM (Erosion Potential Method by Gavrilovic), considers all soil particles (including rocks and mass movement) as well as all slope topography. The EPM considers the whole basin area. The aim of this research is to assess the differences between the two methods in the case study of the Strumica river basin. The results show differences in the quantities of the produced sediment. On the basin level, according to EPM, the quantity of annual produced sediment is 3.38 m3 ha year-1 while RUSLE depicted an annual soil loss at 1.59 t ha-1year-1. When observing just the agricultural land, according to EPM, the annual produced sediment is 4.22 m3 ha year-1 while according to RUSLE, the annual produced sediment is 2.84 t ha-1year-1. The EPM yields higher quantities because it takes into account the gully erosion and mass movement processes.
Internal reserves of cities: a new approach to assessing the transformation of urban space under the influence of brownfields
Authors: Dregulo Andrei M.
Published: January 2025

The disadvantage of the traditional approach to territorial planning of the past years is associated with an underestimation of the essence and multifaceted social brownfields and their importance in the sustainable development of urban areas in post-industrial society. The prospects for the development of the inner space of the city and the quality of life of people largely depend on the presence of brownfields since most of the brownfields can have a negative impact on the environment. This is especially noticeable in large cities and agglomerations. In this paper, we analyze the spatial distribution of brownfields in the largest agglomeration of Russia, comparing their prospects for redevelopment with the analysis of 10 dominant criteria of local priority affecting the transformation of the urban area. The article discusses in detail the reasons for making decisions about the nature of the impact of brownfields and the priority tasks of their elimination: the environmental situation and the economic interests of stakeholders. The study shows that the practice of making decisions on the liquidation of brownfields largely depends on their inclusion in the state register of objects of accumulated environmental damage, which makes it possible to accumulate environmental damage in the near future. However, the entry of accumulated environmental damage into the state register of objects is (1) a practiced procedure because it implies co-financing of the brownfield liquidation project by the federal authorities and (2) an insufficiently objective procedure for assessing the impact (lack of local priority criteria). Based on the conducted research, we believe that the elimination or urbanization of brownfields should be based on the analysis of local priorities in the transformation of urban areas (different from the criteria of modern practice of introducing the state register of brownfields), including the features of the territorial organization of public space, ecological and geographical environment, and public opinion.
Physical-geographical characteristics of the Una river basin – contribution to the analysis of the state and possibilities of radioactive waste disposal in the border zone
Authors: Korjenić Aida
Published: January 2025

The selection of a location for the disposal of radioactive waste, used sources and spent nuclear fuel in the Republic of Croatia began to be considered as early as 1988. However, in the last 10 years, intensive activities have been undertaken regarding the selection of this location. One possible location is Čerkezovac in the Trgovska Gora area, which is located in the Una River basin and less than 1 km away from the border with Bosnia and Herzegovina. It is planned to establish a Radioactive Waste Management Center in Čerkezovac, where all spent radioactive sources located at two sites in Croatia, all institutional waste owned by Croatia, as well as low and intermediate level radioactive waste from the Krško Nuclear Power Plant, would be accommodated. According to the ESPOO Convention (Art. 1, paragraph VIII), transboundary impact implies any impact, not exclusively of a global nature, within the jurisdiction of the signatory state caused by a planned activity, whose physical origin is wholly or partially within the jurisdiction of another signatory state. The majority of the influential surface area of the radioactive waste disposal site (assuming a distance of 5 km from the Čerkezovac site in the Trgovska Gora area) is located within the territory of Bosnia and Herzegovina. This influence could have negative implications on the natural values and protected areas in the Una River valley in Bosnia and Herzegovina, as well as the life of the population.In this paper, based on the analytical-synthetic research approach, the basic physical-geographical characteristics of the Una River basin have been determined. During the analysis, it was concluded that the connection of physical-geographic components within the Una River basin created a series of natural values that formed the basis for the designation of protected areas. This refers to the fluvial and karst landforms that dominate this area, as well as phytogeographic formations, which stand out for their uniqueness and irreplaceability, morphography and morphometry, and the degree of preservation of physical-geographic phenomena and processes. The results of the research can contribute to a better understanding of the potamological characteristics of the Una, its hydrological significance, as well as the need for environmental protection in the context of the possibility of nuclear waste disposal in the border zone of the Una basin. The processing of all parameters relevant to the study and cartographic representation in this paper were performed in the ArcGIS software package.

Authors: Krupnova Tatyana G. , Rakova Olga V. , Simakhina Valeria I. , Vykhodtseva Ekaterina A. , Kochegorov Valeriy M.
Published: January 2025

This work studies the variations in daily and seasonal concentrations of surface ozone (O3), and nitrogen oxides (NO and NO 2) as its precursors in Chelyabinsk, a large industrial city in Russia. A monitoring station located outside the zone of influence of large industrial and transport local sources of air pollution was chosen for the research. The research was carried out during 2019, which can also be considered as a “background” period, because in 2020, during the COVID-19 lockdown, there was a decrease in concentrations of precursors. However, in 2022–2024 concentrations of precursors increased due to increased production capacity. Daily O3 variations are characterized by three peaks that correlate with changes in concentrations of nitrogen oxides (NOx) determined by peak loads and emission intensity of thermal power stations. There are two seasonal peaks of surface O3 concentrations. The spring peak in March is caused by natural processes. In March 2019, an advection of an air mass with different properties and gas composition was observed from areas with powerful sources of precursor gases or saturated with O3 from the south (areas in Kazakhstan). During episodes of high O3 levels, Chelyabinsk was located on the crest of a cyclone, in the warm sector, where low-level jets formed. The summer maximum of surface O3 in June was caused by photochemical reactions during anticyclones and prolonged inversions.

Assessment of urban green infrastructure is a task of strategic planning and tactical implementation of decisions taken in the context of sustainable development of urban territories. One of the directions of such an assessment is to identify instances of land misuse within cities’ public green areas. It reflects the legal fairness of the use of urban green spaces, but currently has a weak scientific justification. Therefore, it is pertinent to develop a methodology for evaluating urban green infrastructure in order to pinpoint areas with inappropriate usage Critical analysis and synthesis allowed us to justify the assessment of the misuse of land within urban green zones as an equal element of the urban green infrastructure assessment system. A geospatial database was created to assess public green spaces. Using the results of remote sensing of territories, as well as the «boxplot» method in combination with the Python programming, the NDVI was calculated, and a classification of vegetation elements and artificial objects located within public green spaces in cities was carried out. Based on the obtained classification categories, a mechanism for identifying «green» areas with misuse of land was proposed, and a list of public green areas with similar violations in St. Petersburg was determined. The practical results of the study include: technology for assessing urban green infrastructure to identify public green spaces with misuse; geospatial databases of public green spaces for St. Petersburg; identified public green spaces with obvious violations of their use, including unauthorized parking, littering, sand dumps, unauthorized placement of industrial, warehouse, retail, transport, or other non-recreational facilities within the boundaries of PGS, vehicle collisions with «green» areas; erroneous inclusion of residential buildings and adjacent courtyards, non-residential facilities, as well as organized parking spaces within PGS’s boundaries.

Contemporary distributed hydrological models are detailed and mathematically rigorous, but their calibration and testing can be still an issue. Often it is based on the quadratic measure of the calculated and observed hydrographs proximity at one outlet gauge station, typically on the Nash-Sutcliffe model efficiency coefficient (NSE). This approach seems insufficient to calibrate a model with hundreds of spatial elements. This paper presents using a multi-dimensional estimator of modeling quality, being a natural generalization of the traditional NSE but which would aggregate data from several hydrological stations using Principal Component Analysis (PCA). The method was tested on the ECOMAG model developed for a sub-basin (24,400 km2, with 15 gauges) of the Ussuri River in Russia. The results show that the presented version of the multi-dimensional NSE with PCA in calibration of spatially-distributed hydrological models has a number of advantages compared to other methods: the reduced dimensionality without loss of important information, straightforward data analysis and the automated calibration procedure; objective separation of the deterministic signal from the noise, calibration using the “informational kernel” of data, leading to more accurate parameters’ estimates. Additionally, the introduced notion of the “compact” dataset allow to interpret physical-geographical homogeneity of the basins in mathematic manner, which can be valuable for hydrological zoning of the basins, hydrological fields analysis, and structuring the models of large basins. There is no doubt that further development and testing of the proposed methodology is advisable in solving spatial hydrological problems based on distributed models, such as managing a cascade of reservoirs, creating hydrological reanalyses, etc.

Fiscal decentralization is closely tied to a country's economic development, with one of its main objectives being the enhancement of public service efficiency, particularly government spending. Government expenditures reflect policy decisions, including providing essential services such as education through HDI. However, many studies dispute the notion that decentralization automatically improves resource allocation efficiency. This research aims to: 1) assess the efficiency of government spending on education in regencies and cities before and after fiscal decentralization, and 2) identify factors influencing this efficiency. The study uses Data Envelopment Analysis (DEA) to evaluate efficiency levels and Tobit regression to analyze the factors affecting efficiency. DEA results show that regencies and cities in Papua have the lowest efficiency (63%), while those in Sumatera have the highest (92%). The Tobit regression model indicates that, for the pre-decentralization period, only the student-teacher ratio is significant, while after decentralization, population size, student-teacher ratio, and region dummy become significant. The findings suggest that improving efficiency in education spending, both before and after decentralization, is critical. Future research should expand the study period, include other sectors like health, and consider the role of the private sector in education. This study contributes to understanding fiscal decentralization's impact on education efficiency and its broader implications for regional and national development.

The anthology of short stories “Ketika Saatnya” is one of the literary works depicting the Buginese woman image written by Darmawati Majid, a Bugis woman. The problem with this article is how the literature illustrates the Buginese woman’s image based on Spivak’s idea of the subaltern and Islamic perspectives on women’s behaviours. This qualitative method, such as postcolonial discourse analysis, involves classifying data according to certain attributes and elements pertinent to the research aims to acquire research outcomes. It categorizes women as a subordinate demographic within society, politics, and geography, subject to the authority of a dominant group, particularly men. Buginese tradition signifies the supremacy of one male faction over another. This research indicates that Bugis women have consistently been placed in subordinate positions. The marginalized minority is portrayed as endeavouring to articulate their viewpoints and attain acknowledgement despite being labelled as “women of underprivileged areas” caught between conventional and Muslim ideologies.

External economic and financial control - Comparative constitutional perspective
Authors: Gera Anton
Published: January 2025

There can be no talk of external economic and financial control in a dictatorial state. Consequently, external control is a significant component of democratic states. As for the definition of external audit, it consists of an assessment carried out by an independent and competent entity. This assessment allows the compilation of an opinion in relation to national or international standards on the financial status, internal control of the institution, procedures and any activity of a given institution. Audit is an independent assessment that aims to obtain evidence in relation to a specific object and its objective assessment to determine to what extent predetermined criteria have been met or not. The concept of audit can be applied both in the public and private sectors, where it was invented. Regarding auditing in the public sector, there should be a distinction between internal and external audit. Internal Audit is an independent activity that provides objective assurance and advice to management designed to add value and improve the operations of a public entity. As for the origins of auditing in general through the use of inventory, it is found in Domesday, created by William I of England. In the late Middle Ages, there are references to auditors and auditing in Italy, France and England as an activity and as a formalization of the institution of control. In this sense main objective of this manuscript is a comparative constitutional perspective of the economic and financial control.
