Balance model of dissolved nitrogen and phosphorus transportation and metabolism in the Dniester estuary system
Authors: Ilyin Yu. P. , Berlinsky N. А. 
Published: July 2022

In order to obtain quantitative estimates of water and nutrient fluxes into the Dniester estuary system, the biogeochemical modeling approach recommended by the international program LOICZ was used. The integral (reservoir) model of the system consists of balance equations for water, salinity and dissolved forms of nitrogen and phosphorus. The research involves the information of the annual cycle (from November 2003 to October 2004) of hydrochemical studies at the mouth of the Dniester River and at the exit of the estuary to the Black Sea carried out within the framework of the international project GEF/BSERP, as well as the data of hydrometeorological observations at Belgorod-Dniestrovsky hydrometeorological station, Tzargorod Gyrlo hydrometeorological post and Odesa State Environmental University training base.
The water balance equation takes into account the flows of river runoff, precipitation and evaporation. Uncertainty associated with the failure of taking into account the underground runoff still remained. The use of an independent empirical assessment of the advective water flow through the Tzargorod Strait made it possible to estimate the degree of non-stationarity of the model equations on the scale of variability from a month to a year. The flow of turbulent exchange between the estuary and the adjacent sea is estimated by means of the salt balance equation and is determined by the difference between the estuary and marine water salinity.
By calculating the monthly and yearly values it was established that, for the Dniester estuary and similar systems, the water balance equation can be considered as stationary while the precipitation and evaporation flows can be neglected: compared to the river runoff, advective and turbulent water exchange flows they are several orders of magnitude lower, that is, below the limit of errors of horizontal water flows.
The joint action of the advective and diffusion flows ensured the overall removal of nutrients from the estuary ecosystem. During the annual cycle of 2003-2004 observations 73% of total dissolved phosphorus and 92% of total dissolved nitrogen entered the sea from the estuary compared to the amount reaching the estuary with the Dniester River runoff.
Stoichiometric analysis of biogeochemical residuals showed that, for most of the year, the ecosystem of the Dniester estuary produced organic matter and consumed dissolved phosphorus, while the nitrogen fixation in the ecosystem outweighed the denitrification process.
Forecasting the atmospheric air pollution caused by nitrogen dioxide in the City of Odesa
Authors: Chugai A. V. , Terzeman V. V. 
Published: July 2022

In most of Ukrainian large cities with a high concentration of population the air quality often does not meet the requirements. The air quality is also a critical component for Odesa, a recreational and resort center of Ukraine. Moreover, Odesa is a city with a million inhabitants and a large number of vehicles, freight traffic resulting from the presence of the seaport. And nitrogen dioxide is one of the main pollutants. It is emitted to the air basin mainly by motor vehicles.
The paper presents the results of testing the certain methods of short-term forecasting of the atmospheric air nitrogen dioxide-related pollution level in Odesa. The study is based on the data taken from the materials of the National Report on the State of the Environment in Ukraine and the observations of air pollution using the network of stationary observation points.
The obtained results of the forecast for the winter period using the UkrSIHMI's method indicated that the dynamics of changes in the actual values of the indicator Q coincides with the prognostic values of such indicator. In summer the actual value of Q in almost all cases coincides with the prognostic indicators. The accuracy of the forecast according to the UkrSIHMI's method for the winter period averaged 96.6 %, and for the summer period – 98.3 %. According to the method of pattern recognition for the winter and summer periods the percentage of accuracy of predictions was only 67 %.
The UkrSIHMI's method proved to be more reliable than the method of pattern recognition. The low percentage of reliability of the forecasting results obtained via the method of pattern recognition may be due to modeling problems and small variance of pollution classes in the studied sample, as well as to the focus of the methodology on determining a pollution class rather than a level of pollution. The disadvantage of using the UkrSIHMI's method is the impossibility of using it in autumn and spring.
Forecasting the air pollution is one of the main ways to solve air quality problems in both industrial and urban agglomerations. Development of an effective prognostic scheme for forecasting the air pollution in our city can prevent further air quality deterioration.

Background: Squalene, as an isoprene, is one of the components of amaranth oil and makes up about 8% of this oil. Squalene has anti-inflammatory and antioxidant effects that have been considered in many studies. In people with uncontrolled diabetes, there is an increase in total cholesterol and low-density lipoprotein (LDL) alongside a decrease in high-density lipoproteins (HDL).According to studies, squalene can be useful in lowering total cholesterol and triacylglycerol.Objective: The aim of this study was to investigate whether squalene has an effect on lipid profile and a number of oxidative biomarkers in patients with type 2 diabetes.Methods: In the present study, 30 healthy volunteers were selected as the control group and 120 volunteers with type 2 diabetes mellitus (T2DM) were selected. Subjects with diabetes were randomly divided into 4 groups. Group 1 was untreated with squalene and groups 3, 4, and 5 were treated with different doses of squalene for 84 days. Lipid profiles and oxidant biomarkers were examined on days 1, 14, 28, 56, and 84 according to the relevant protocols in all groups.Results: Significant differences (P < 0.05) were observed between control and diabetic groups in the study of cholesterol, triglycerides, LDL, HDL, very low-density lipoproteins (VLDL), oxidized low-density lipoprotein (Ox-LDL), and malondialdehyde. There was a significant difference between the studied groups in the levels of parameters expressed in some different doses and days.At the levels of the parameters expressed in some doses and different days, a significant difference was observed between the groups treated and untreated with squalene.Conclusion: This study shows that squalene as a bioactive compound can be effective to manage certain symptoms of diabetics including HDL, LDL, total cholesterol, and VLDL. From our findings, we observed that squalene consumption over the duration of 84 days resulted in increased levels of HDL in diabetic patients. It also resulted in decreased levels of total cholesterol, LDL, and VLDL in diabetic patients. Keywords: Squalene, lipid profile, oxidative biomarkers, diabetes mellitus

Aim: The detection and segmentation of cerebral microbleeds (CMBs) images are the focus of clinical diagnosis and treatment. However, segmentation is difficult in clinical practice, and missed diagnosis may occur. Few related studies on the automated segmentation of CMB images have been performed, and we provide the most effective CMB segmentation to date using an automated segmentation system.Materials and Methods: From a research perspective, we focused on the automated segmentation of CMB targets in susceptibility weighted imaging (SWI) for the first time and then constructed a deep learning network focused on the segmentation of micro-objects. We collected and marked clinical datasets and proposed a new medical micro-object cascade network (MMOC-Net). In the first stage, U-Net was utilized to select the region of interest (ROI). In the second stage, we utilized a full-resolution network (FRN) to complete fine segmentation. We also incorporated residual atrous spatial pyramid pooling (R-ASPP) and a new joint loss function.Results: The most suitable segmentation result was achieved with a ROI size of 32 × 32. To verify the validity of each part of the method, ablation studies were performed, which showed that the best segmentation results were obtained when FRN, R-ASPP and the combined loss function were used simultaneously. Under these conditions, the obtained Dice similarity coefficient (DSC) value was 87.93% and the F2-score (F2) value was 90.69%. We also innovatively developed a visual clinical diagnosis system that can provide effective support for clinical diagnosis and treatment decisions.Conclusions: We created the MMOC-Net method to perform the automated segmentation task of CMBs in an SWI and obtained better segmentation performance; hence, this pioneering method has research significance.
