The object of the study is the Sukhachivske industrial site, tailings storage facility section I (Ukraine). The main reason for conducting the study is to establish actual and forecast numerical values of absorbed and exposure dose rates. The state of radiation contamination of the tailing’s storage facilities of the Sukhachivske industrial site was analyzed. The actual and prolonged levels of equivalent dose rate, absorbed dose rate, and total personnel exposure dose were determined. Dependencies were established that allow determining approximate numerical values for specific conditions and certain areas using the finite element method with subsequent transfer of values to 2024–2027. Based on the conducted studies, the dynamics of contamination at the Sukhachivske tailings storage facility section I was predicted. The estimated, forecast, and actual values of personnel exposure doses were determined for the period from 2010 to 2023. New methods and algorithms for instrumental measurement of radiation parameters at the tailing’s facilities of the former uranium production facility of the Prydniprovsky Chemical Plant have been developed. The state of radiation contamination of the tailing’s facilities of the Sukhachivke industrial site has been analyzed. The actual and prolonged levels of equivalent dose rate, absorbed dose rate, total personnel exposure dose, and contamination levels of the territories adjacent to the tailings facilities have been determined. Monitoring studies over ten years have allowed to determine the actual values of the exposure dose rate, which range from 0.08 to 0.21 μSv/h with certain local values up to 0.26 μSv/h. In general, the total personnel exposure dose does not exceed 1.1–1.4 mSv/year. The obtained data on prognostic values, in turn, make it possible to predict the further radiation situation at the Sukhachivske industrial site in the coming years. As well as to improve the system for calculating the total effective radiation dose, both to the personnel of the radiation-hazardous facility and to the population living near the industrial site.
Study of lyophilic properties of natural clinoptilolite as a sorbent of oil and oil products
Authors: Hrynyshyn Stanislav , Znak Zenovii 
Published: January 2025

The object of research is natural clinoptilolite as a potential sorbent in the processes of water and soil purification from oil, petroleum products (A-95 gasoline, kerosene), industrial oil, benzene, toluene, hexane, water-gasoline emulsions, as well as water-organic condensate. It is known that this material has a high adsorption capacity for various organic media. Therefore, the lyophilic properties of different fractions of clinoptilolite in relation to the specified environments were investigated.
The lyophilic properties of clinoptilolite were studied using the lying drop method to measure the marginal wetting angle of different zeolite fractions using the specified media. The data obtained determined the suitability of clinoptilolite for cleaning soils and waters from these liquids.
The dependence of the wetting of clinoptilolite on the dispersion of clinoptilolite was established. All clinoptilolite fractions are characterized by high lyophilicity in all media except oil. The wettability of clinoptilolite with oil and the corresponding work of adhesion significantly depends on its dispersion. It was established that with an increase in the size of clinoptilolite particles from 0.1 to 2.5–3.0 mm, the work of adhesion increases from 13.5·10-3 to 51.2·10-3 J/m2. The influence of the surface morphology of clinoptilolite may cause this. An increase in temperature in the clinoptilolite-oil system contributes to the wetting of small fractions of zeolite with oil.
The obtained experimental data show that natural clinoptilolite with a wide fractional composition can be used to purify natural and wastewater waters and soils from the indicated organic and water-organic environments. At the same time, only clinoptilolite fractions over 1 mm are suitable for oil sorption.

The object of research is the problem of uniform distribution of bulk materials across the width of the working elements of the separation equipment. Such a problem limits the productivity and quality of the process of separation of bulk materials by aerodynamic and dimensional characteristics. To ensure uniformity of the layer of bulk material across the width, an integrated design of the loading device is proposed, which consists of a gable surface with a variable angle of inclination from the center of the feed to the extreme limits of the device. The working part of the device is made in the form of surfaces of variable width, and the width of each slope of the surface increases proportionally to the distance to the walls of the housing. This allows for controlled distribution of the material across the width. The studies were conducted using analytical and experimental methods. To determine the parameters of the movement of the bulk grain medium along the integrated inclined surface, analytical expressions were obtained that take into account the parameters of the proposed loading device and the properties of the bulk grain material. The patterns of change in the rate of descent of particles of bulk grain material from the inclined surface, as well as the dependence of the velocity of their fall to the hopper bottom, were obtained. Experimental studies were based on high-velocity video recording of the process with identification of dynamic parameters of bulk material and comparison with modeling data. The adequacy of the model was confirmed by experiments with a difference of up to 3.6 %. The influence of the following significant factors on the final velocity of particles of bulk grain material (BGM) was established: the length of the sloping surface at the level of 47.5–116.5 %, then the distance from the surface to the hopper bottom at the level of 76.7–85.6 % and the angle of inclination of the sloping surface at the level of 24.4–41.1 %. The ranges of variation of the BGM particle velocities were established: the initial velocity of particles on the sloping surface 0.82–1.27 m/s, the velocity of particles descending from the sloping surface 0.85–1.43 m/s, the velocity of falling particles 0.68–1.47 m/s. The research results were rational parameters of the integrated loading device, which provides excellent particle movement velocities and leads to uniform distribution of bulk grain material across the width of the separation equipment with an inlet to outlet ratio of (1:5). The results obtained prove the existence and method of scientific and technical solution to the problem, create conditions for further research and design of separation equipment with high technological indicators.

Aim. To explore cardiac interoception (probed by interoceptive accuracy in the mental tracking task) and its association with psychological characteristics in groups of patients with symptomatic and asymptomatic premature ventricular contractions (PVC) and controls.Material and methods. The study included 34 patients with PVC [17 individuals formed the group with symptomatic PVC (median age: 43 years) and 17 — formed the group with asymptomatic PVCs (median age: 42 years)] and 17 healthy subjects without cardiovascular diseases (median age: 40 years) in the control group. All study participants underwent 24-hour blood pressure and Holter monitoring. Interoception was assessed by interoceptive accuracy probed by behavioral test — mental tracking task. Participants completed questionnaires to assess levels of depression, anxiety, alexithymia and body perception.Results. Patients with symptomatic PVC had significantly higher levels of personal (p<0.001) and situational (p=0.011) anxiety compared to controls (p<0.001). The total alexithymia index was elevated in both symptomatic (p=0.004) and asymptomatic patients (p=0.028) compared to controls. Body perception (supradiaphragmatic scale of the Body Perception Questionnaire) was significantly higher in the group with symptomatic PVC compared to both the asymptomatic group (p=0.003) and the control group (p<0.001). A trend towards higher interoceptive accuracy was found in the group with symptomatic PVC (p=0.021; after correction p=0.064). No correlation was found between the level of interoception and psychological characteristics.Conclusion. Our findings suggest a possible role of cardiac interoception in the development of PVC symptoms, which may serve as a basis for the development of non-invasive and non-pharmacological treatment methods aimed at reducing the intensity of PVC symptoms, taking into account patients’ levels of anxiety, alexithymia and body perception.

Aim. To evaluate the quality of drug treatment of patients with cardiovascular diseases (CVD) at the remote stage of follow-up after hospitalization for new coronavirus infection (COronaVIrus Disease 2019, COVID-19) within the framework of the prospective TARGET-VIP registry.Material and methods. 1,130 people were included in the registry. The 473 (54.8%) patients with CVD were selected of the 863 patients discharged from the hospital with a diagnosis of COVID-19.Results. The frequency of proper prescriptions of medicines upon discharge from the hospital was 60%, after 3 years this indicator decreased to 41.4% (p<0.001). During the 3-year follow-up, a clear trend was recorded in a decrease in the frequency of intake of all drugs, while for some groups of drugs this decrease reached statistically significant differences. The frequency of taking angiotensin converting enzyme inhibitors in patients with cerebral stroke, statins in coronary heart disease and statins in patients with cerebral stroke MI did not change significantly, although the frequency of taking these drugs at all stages of follow-up was very low and did not exceed a third of the required prescriptions. New CVD were detected in 51 patients, and the average frequency of taking proper medications for CVD was higher than in patients with already known stable CVD, 74.2% and 66.2%, respectively, p=0.047. The presence of CVD did not affect the quality of therapy in the new cases of CVD, the average frequency of taking the necessary drugs in these groups was 77.8 and 63.2%, respectively, p=0.074.Conclusion. The quality of CVD therapy was insufficient at all stages of long-term follow-up: the frequency of proper prescriptions upon discharge from the hospital was 60%, after 3 years this indicator decreased to 41.4%. A clear trend was revealed in a decrease in the frequency of taking all drugs, while for some groups of drugs this decrease reached statistically significant differences. The quality of cardiovascular pharmacotherapy was higher with the appearance / development of new CVD in comparison with the group of stable patients with CVD, there was no significant improvement in the quality of therapy for previously observed CVD.

The implementation of discussion in learning activities based on problem in schools could improve students' critical thinking skills. However, in its implementation, there were still several problems, one of them was the lack of students' ability in solving the problems. So, there needs to be a learning model that could create the learning based on problem. This research aimed at knowing 1) difference of students' critical thinking abilities, 2) the effectiveness of learning using POGIL model based on SSI students' critical thinking skills. This research was conducted in the even semester of 2021/2022 Academic Year at X MIPA grade of Senior High School Taruna Mandiri Pekanbaru on electrolyte and non-electrolyte solutions materials. It was an experimental research with pretest and posttest nonequivalent control group design. T-test (knowing difference of students' critical thinking abilities) and N-gain test (knowing the level of effectiveness) were used for analyzing the data. The results of this research showed that 1) there was a difference of students' critical thinking skills between the experiment and control groups, the posttest average scores of critical thinking skills in the experiment group was 82.00 and the control group was 75.21, the result of t-test obtained that a significance value was 0.002 < 0.05, so that null hypothesis (Ho) was rejected and alternative hypothesis (Ha) was accepted. 2) Learning using the POGIL (Process Oriented Guided Inquiry Learning) model was effective on students' critical thinking skills. The N-gain value of the experimental group from each student: there were 28 students in the high N-gain category (93.33%) and 2 students in the medium N-gain category (6.67%) who were into the effective category. The conclusion was learning using the POGIL (Process Oriented Guided Inquiry Learning) model was effective on students' critical thinking skills.
