Published: January 2022

The theory of combined systems of extreme control, which is used in technical systems, was developed and adapted in socio-ecological-economic systems. For example, river basins are such systems. A combined extreme control system has been formalized to control the dilution of mineralized mine waters in river sections. A mathematical model of the distribution of water masses and pollution in river beds from point and diffuse sources is proposed on the basis of a system of difference balance equations under the influence of stochastic uncontrolled disturbances. With regard to such conditions as adequate instrumentation, a combined control system has been developed that uses decision-making according to environmental and economic criteria based on the analysis of input and output data simultaneously, identification and tracking of the optimum in conditions of displacement under the influence of the disturbances of extreme characteristics of the system. The structural and functional diagram is represented by the open-loop diagram, the identification of which is carried out on the basis of modeling the process of water dilution in various situations at a specific object. A closed part with a recognition system as a corrector provides feedback. Formalized mathematical models of the dynamics of water masses and pollution from point and diffuse sources are of a general nature and can be used for the basins of other rivers. The extreme control system can adapt to the hydrological conditions and water quality parameters of a particular river.
A mathematical model has been formalized for the combined extreme control of mine water dilution in the section of the Ingulets river. The water for dilution comes from a storage pond in the Svystunov gully. Regulatory actions that maintain water quality without exceeding the normative values ​​of maximum permissible discharge are determined. At the same time, water consumption for dilution is minimized. The scenario analysis of the options showed a saving of up to 30% of water resources, namely 17.5 million m3, compared to the dilution carried out in February-March 2021 according to the existing individual regulations.

The results of experimental researches on studying of features of formation of a water mode of soils, water consumption processes, and corn yield under different schemes of irrigation pipelines (IP) under subsurface drip irrigation (SDI) in the Steppe of Ukraine. The wetting zone of dark-chestnut residual-saline sandy soil (SI "SF "Brylivske") changed. There is a shift of the center relative to the drip water outlet into deeper horizons of the soil profile (up to 52 cm) with the increasing norm; soil layer 0-15 cm is almost not moistened, regardless of watering rate. At a distance of IP 1,0 m closing of wetting zones, occur at irrigation rates of 2,7 m3/100 running meter (r. m), and at a distance of IP 1,4 m does not occur even at irrigation rates of 3,7 m3/100 r. m, while the depth of wetting reaches 90 cm. The wetting zone of chernozem sandy loam on the loess species (SI "SF "Velyki Klyny") with irrigation rates of 2,7 m3/100 r. m was observed on the soil surface. The maximum depth of wetting, with irrigation norms of 3,7 m3/100 r. m, reached 70 cm with a maximum diameter of 79 cm at a depth of 25 cm. Closing of wetting zones was not observed.
Studies at SI "SF "Brylivske" have confirmed that the depth of IP placement (on the soil surface or at a depth of 30 cm) influenced the formation of the soil water regime and the corn yield. The minimum total water consumption was 6271 m3/ha under drip irrigation (DI) (IP 1,4 m), 17 % more than SDI (IP 1,4 m), and 29% more than SDI (IP 1,0 m). The highest yield was obtained in the case of DI (IP 1,4 m) of 15,72 t/ha. SDI (IP 1,0 m) received 13,93 t/ha, and SDI (IP 1,4 m) received 13,50 t/ha.
The distance between the IP in 1,0 m and 1.4 m of the SDI system did not significantly affect corn yield (13.93 and 13.50 t/ha, respectively), but at a distance of IP 1.4 m, the water consumption ratio was 6.8% less compared to IP 1,0 m. The value of the irrigation rate in the variants SDI (IP 1.0 m) was higher than SDI (IP 1,4 m) by 13,6 %. Therefore, in terms of irrigation water consumption and capital expenditures, the SDI (IP 1,4 m) is more economical.
Experimental studies conducted in the SI "SF "Velyki Klyny" show that the depth of placement of IP (on the soil surface or at a depth of 20 cm) did not affect the corn yield. For DI (IP 1,0 m) the yield was 12,00 t/ha and for SDI (IP 1.0 m) was 12,10 t/ha, with a water consumption ratio of 533,8 m3/t, and for DI (IP 1,0 m) by 3,6 % more.
The research results confirm the importance of the parameters of SDI system for the formation of soil water regime and, accordingly, the realization of the potential of varieties and hybrids of crops for their cultivation by SDI.

Published: January 2022

The current state of water quality formation in surface water bodies, which serve as sources of drinking water supply in the Dnieper river basin, was considered. The water treatment technologies currently used in Ukraine, were analyzed. The inconsistency of these technologies with the current water quality in these sources of water supply was established, as these technologies are not quite suitable for the purification of water with a significant organic component of any genesis. It was found that one of the main factors that influences the quality of water in water bodies in the warm period is phytoplankton, especially during their "flowering. The factors accompanying this phenomenon were shown, the development trends and their influence on the operating water treatment systems were analyzed. It was considered the feasibility of using reagents with the effect of oxidation of the organic component of the source water, in particular chlorine dioxide, the use of which is effective in disinfection of chlorine-resistant microbiota and phenols oxidations. Moreover, in the conditions of the expected increase in the concentration of mycocystins, chlorine dioxide can be, by analogy with ozone, a fairly effective oxidant of these toxins with a prolonged disinfection effect.
The potential development areas of water treatment systems by intensifying bio-physico-chemical processes on the basis of the existing typical capacitive and package units of water treatment plants are given. The perspective areas of scientific and technological developments for substantiation of effective solutions on modernization of existing water treatment facilities were established in these conditions, namely it is reasonable to consider only those solutions, which provide effective purification of water with high concentration of phytoplankton without comprehensive or radical change of water treatment technology. That is, these approaches should make maximum use of existing treatment facilities, either by their reconstruction, or with the use of new reagents, or a combination of both.

Authors: Adhikari Manandhar Seerina , Amatya Mrigendra 
Published: January 2022

Introduction: Blood grouping, bleeding time (BT) and clotting time (CT) are important hematological parameters investigated before any surgical procedure. The association of blood groups with many diseases are established, such as epistaxis with blood group “O”. This study aimed to assess the relationship of BT and CT among different blood groups and to find any gender difference in these parameters.
Materials and methods: A cross-sectional observational study was conducted among healthy medical students. Blood grouping was done by agglutination method, BT by Duke’s method, and CT by capillary tube method. Mean bleeding and clotting times (seconds) were compared among groups.
Results: The study was completed in 351 students (160 males, 191 females), with age ranging from 19-23 years. Both BT and CT values were highest in the blood type O, BT was lowest in type B, and CT was lowest in type AB, although the differences were statistically not significant (p>0.15). Females had higher values of BT as well as CT than males (p values <0.001). A very highly significant correlation between the bleeding and clotting times was also noticed (Pearson’s correlation coefficient, P = 0.495, p<0.001).
Conclusions: The study hinted a tendency for higher risk for hemorrhagic condition and lower risk for thrombotic event in blood group O compared to groups A, B or AB. Multicentric study including larger population with the emphasis on finding plasma vWF level may be helpful to verify findings, identify the risk groups, and take prior preventive measures.
On Karol Wojtyła’s Aristotelian Method Part II Induction and Reduction as Aristotelian Induction (ἐπαγωγή) and Division (διαίρεσις)
Authors: Wagner Daniel C. 
Published: January 2022

This is the second of a two-part study treating Karol Wojtyła’s Aristotelian methodology. Having presented Aristotle’s method of induction (ἐπαγωγή/epagoge) and analysis (ἀνάλῠσις/analusis) or division (διαίρεσις/diairesis) in Part I, Part II discloses the logical form and force of Wojtyła’s method of induction and reduction as Aristotelian induction and division. Looking primarily to the introduction to The Acting Person, it is shown that Wojtyła utilizes the logical forms of reductio ad impossibile and reasoning on the hypothesis of the end, or effect-cause reasoning, which is special to the life sciences and the power-object model of definition as set down by Aristotle. By use of this Aristotelian methodology, Wojtyła obtains definitive knowledge of the human person that is necessary and undeniable: he discloses the εἶδος (eidos) or species of the person in the Aristotelian, Thomistic, and Phenomenological sense of the term.
Human Person in the Code of Canon Law of John Paul II
Authors: Přibyl Stanislav 
Published: January 2022

The Code of Canon Law, promulgated by John Paul II in 1983, is a synthesis of the earlier 1917 Code and the doctrine of the Second Vatican Council. The Code contains norms which go well beyond a reform of the inner legal relations within the Catholic Church. A lot of them deal with the value and dignity of the human person, which shows a clear impact of the pontificate of John Paul II, who put a lot of emphasis on the given issue. The article discusses the fields of legal regulations in the Code which touch upon the issue of the human person, esp. freedom of religion, protection of unborn life, social rights, legal standing of women and the education of future generations. It points out the main difference between civil law (which also serves the dignity of the human person) and canon law, namely, the latter aims at the salvation of souls.

Published: January 2022

Nanozymes are particles with diameters in the range of 1–100 nm, which has been widely studied due to their biological enzyme-like properties and stability that natural enzymes do not have. In this study, several reducing agents with different structures (catechol (Cc), hydroquinone (Hq), resorcinol (Rs), vitamin C (Vc), pyrogallic acid (Ga), sodium citrate (Sc), sodium malate (Sm), and sodium tartrate (St)) were used to prepare colloidal gold with a negative charge and similar particle size by controlling the temperature and pH. The affinity analysis of the substrate H2O2 and TMB showed that the order of activities of colloidal gold Nanozymes prepared by different reducing agents was Cc, Hq, Rs, Vc, Ga, Sc, Sm, St. It was also found that the enzyme activity of colloidal gold reduced by benzene rings is higher than that of the colloidal gold enzyme reduced by linear chains. Finally, we discussed the activity of the colloidal gold peroxidase based on the number and position of isomers and functional groups; and demonstrated that the nanozymes activity is affected by the surface activity of colloidal gold, the elimination of hydroxyl radicals and the TMB binding efficiency.

Published: January 2022

Background:The development of atherosclerosis was considered as the common cause of the stenosis of coronary artery grafts. Left internal mammary artery (LIMA) was the best artery graft for further effectiveness of coronary artery bypass grafting (CABG). We sought to assess the impact of known conventional cardiovascular risk factors (RFs) on LIMA graft stenosis.Methods:A retrospective study including 618 participants, who had recurrence of chest pain after CABG, aged ≥18 years, hospitalized for coronary angiography in Beijing Anzhen hospital between 2010 and 2017 was performed. All the participants were confirmed to have LIMA graft. Multivariate analysis was conducted to determine the relationship between conventional RFs and LIMA graft stenosis.Results:Of the study, 220 (35.6%) participants continued to smoke, 504 (81.6%) were overweight or obese, and 411 (66.5%) and 242 (39.2%) reported concomitant hypertension and diabetes, respectively. LIMA graft stenosis occurred in 161 participants (26.1%). Postoperative smoking, a CABG duration of ≥10 years and hyperglycemia without diabetes had an increased risk of LIMA graft stenosis, the odds ratio (OR) was 1.86 [95% confidence interval (CI): 1.26–2.78], 2.24 (95%CI:1.33–3.478), and 2.44(95% CI:1.39–4.32), respectively. Statin use (OR, 0.28; 95% CI: 0.25–0.5) and low-density lipoprotein cholesterol (LDL-C) &lt; 1.8 mmol/L (OR, 0.27; 95% CI: 0.14–0.53) had a significantly decreased risk of LIMA graft stenosis. While, only 15.4% (95/618) achieved the target LDL-C level.Conclusions:Postoperative smoking and hyperglycemia without diabetes had an increased risk of LIMA graft stenosis. Statin use and LDL-C &lt;1.8 mmol/L decreased the risk.

Introduction:Little is known about the clinical performance of single-chamber leadless pacemaker (LLPM) in patients without atrial fibrillation (AF) as pacing indication. The aim of this study was to describe the clinical characteristics of patients who underwent single chamber LLPM implantation at three tertiary referral centers and to compare the safety and effectiveness of the single-chamber LLPM among patients with or without AF.Materials and Methods:All the consecutive patients who underwent LLPM implantation at three referral centers were analyzed. The indications to LLPM in a real-world setting were described. The study population was divided into two groups according to AF as pacing indication. We assessed the procedure-related complications; moreover, we compared syncope, cardiac hospitalization, pacemaker syndrome, and all-cause death recurrence during the follow-up between patients with and without AF as pacing indication.Results:A total of 140 consecutive patients (mean age, 76.7 ± 11.24 years, men 64.3%) were included in the study. The indication to implantation of LLPM was permanent AF with slow ventricular response (n: 67; 47.8%), sinus node dysfunction (n: 25; 17.8%), third atrioventricular block (AVB) (n: 20; 14.2%), second-degree AVB (n: 18; 12.8%), and first degree AVB (n: 10; 7.1%). A total of 7 patients (5%) experienced perioperative complications with no differences between the AF vs. non-AF groups. During a mean follow-up of 606.5 ± 265.9 days, 10 patients (7.7%) died and 7 patients (5.4%) were reported for cardiac hospitalization; 5 patients (3.8%) experienced syncope; no patients showed pacemaker syndrome. No significant differences in the clinical events between the groups were shown. The Kaplan–Meier analysis for the combined endpoints did not show significant differences between the AF and non-AF groups [hazard ratio (HR): 0.94, 95% CI: 0.41–2.16; p = 0.88].Conclusion:Our real-world data suggest that LLPM may be considered a safe and reasonable treatment in patients without AF in need of pacing. Further studies are needed to confirm these preliminary results.

Published: January 2022

A new gravimetric geoid model, the KW-FLGM2021, is developed for Kuwait in this study. This new geoid model is driven by a combination of the XGM2019e-combined global geopotential model (GGM), terrestrial gravity, and the SRTM 3 global digital elevation model with a spatial resolution of three arc seconds. The KW-FLGM2021 has been computed by using the technique of Least Squares Collocation (LSC) with Remove-Compute-Restore (RCR) procedure. To evaluate the external accuracy of the KW-FLGM2021 gravimetric geoid model, GPS/leveling data were used. As a result of this evaluation, the residual of geoid heights obtained from the KW-FLGM2021 geoid model is 2.2 cm. The KW-FLGM2021 is possible to be recommended as the first accurate geoid model for Kuwait.
