The Long and the Short of It: Approaching the (Un-)Representable in China Miéville’s “The Tain” (2002) and “The Condition of New Death” (2014)
Authors: Reinfandt Christoph
Published: June 2021

How can the genre of the short story accommodate the ‘inflationary tendency’ of weird fiction (Carl Freedman)? This article will trace how a very long and a very short story by China Miéville establish their respective weird elements in order to function as ‘placeholders for the unrepresentable’ (China Miéville). As will be shown, “The Tain” frames the weird in an elaborate and intricatenarrativeconstruction which is clearlyliterarywhile “The Condition of New Death” is basicallyexpositoryand partly relies on thenon-literarygenre conventions of the academic report and the manifesto. In both instances, however, there is a reflexive turn which insists on the text itself not only in its representational but also in its performative (telling stories, writing) and material (print, paper, screen) dimensions as a constitutive part of what makes reality real for human beings. The article concludes with a brief placing of the New Weird short story in the wider field of (post-)modern(ist) literature and fiction and in the conceptual shift from deconstruction to more recent theoretical approaches like Actor-Network-Theory and the New Materialisms.
Formation of Ultrafine Single-Variant Martensite from Prior Ferrite + Cementite Microstructure and Its Mechanical Properties
Authors: Torizuka Shiro , Oya Ryusuke , Prasad Kartik , Ito Atsushi
Published: June 2021

In the present investigation, changes in the single-variant martensite structure of 0.1%C-2%Si-5%Mn steel with a decrease in the prior austenite grain size have been investigated. While prior austenite grain size in the range of 150 to 24 µm led to the formation of martensite with a multi-packet and multi-block structure, a single packet and multi-block martensite structure formed from the prior austenite grain size of about 7 µm. Furthermore, the prior austenite grain size of about 2 µm led to the formation of a single-variant (single-block) martensite structure. This microstructural analysis indicates that the critical prior austenite grain size to form martensite with a single-variant structure is about 2 µm. The tensile strength (TS, 1,490 MPa), uniform elongation (UEL, 7.1 %), and total elongation (TEL, 14.2 %) of the single-variant martensite was found to be higher than that of the multi-packet multi-block martensite (TS = 1,270 MPa, UEL = 6.2 %, and TEL = 13.6 %). The improvement in the mechanical properties of the single-variant martensite was attributed to enhancement in its strain-hardening rate as a result of change in the structure from the multivariant to the single variant.

Published: June 2021

Background: A postinfarction ventricular septal defect (pVSD) as a complication of acute myocardial infarction (AMI) is associated with high mortality. This retrospective, single-center study aimed to identify predictors of early and long-term outcomes in patients undergoing primary surgical repair of pVSD managed by various surgical techniques.
Methods: We reviewed data from 77 consecutive patients who underwent primary surgical repair after pVSD in our institution. Prospectively collected demographic and perioperative data were analyzed retrospectively. Predictors of 30-day mortality and long-term outcome were assessed.
Results: pVSD was anterior in 45 patients (58.4%) and posterior in 32 (41.6%). Buttressed mattress suture (n = 9, 11.7%), simple single septal patch (n = 34, 44.2%), simple double septal patch (n = 2, 2.6%), sandwich double patch (n = 1, 1.3%), and the infarct exclusion technique (n = 31, 40.3%) were performed for surgical closure. Fifty-three patients (68.8%) had preoperative cardiogenic shock. The 30-day mortality was 42.8% (33 patients). Independent risk factors of 30-day mortality were duration between AMI and surgery <7 days (odds ratio [OR] 5.229, P = .011), preoperative absence of diuretics (OR 6.913, P = .005), and preoperative cardiogenic shock (OR 3.558, P = .011). Cumulative survival rates at 1, 5, and 10 years were 57.1%, 57.1%, and 31.2%, respectively.
Conclusion: In pVSD, the 30-day mortality remains high, and preoperative cardiogenic shock significantly influenced mortality in our study. None of the surgical techniques or materials used in our investigation influenced the outcome.

Published: June 2021

Background: This study aimed to examine the long-term functional results of patients with isolated discrete subaortic stenosis who underwent subaortic membrane resection and myectomy, using transthoracic M-mode echocardiography and 2D speckle-tracking echocardiography.
Methods: Twenty patients operated for isolated discrete subaortic stenosis and 31 controls were included in the study. Patients underwent subaortic membrane resection and myectomy. During the long-term follow up, patients were evaluated with transthoracic M-mode echocardiography and 2D speckle-tracking echocardiography for functional assessment.
Results: The mean age at operation and mean duration of follow up was 8.1±5.6 years and 7.2±3.3 years, respectively. Interventricular septal thickness at diastole (0.9±0.1 vs. 0.8±0.1 cm, P = 0.001), ejection time (285.7±26.2 vs. 261.2±24.3 msec, P = 0.001), and aortic strain (15.6±3.7 vs. 10.5±4.0, P < 0.001) were significantly higher in patients. On the other hand, ejection fraction (64.9±6.1 vs. 75.1±5.4 %, P < 0.001), fractional shortening (35.0±5.1 vs. 43.7±5.1, P < 0.001), and corrected velocity circumferential fiber shortening (0.12±0.02 vs. 0.17±0.03, P < 0.001) were significantly lower, when compared with the controls. Longitudinal strain value significantly differed among the groups, with patients having significantly lower strain (18.8±1.8 vs. 20.1±2.1, P = 0.021).
Conclusion: In patients operated for isolated discrete subaortic stenosis, aortic gradient seems to continue in the long-term, with the persistence of low longitudinal strain.
Congenital Lobar Emphysema: Perioperative Evaluation and Management
Authors: Elsawy Abd Elaziz Montaser , Gaber Elsayed Mohamed , Ahmed El-hag Aly Mohamed
Published: June 2021

Background: Congenital lobar emphysema (CLE) is a lung malformation characterized by overdistension and air trapping in the affected lobe. It is one of the causes of neonatal and infantile respiratory distress. This study aimed to evaluate our experience regarding perioperative and surgical management in children with CLE.
Methods: A retrospective observational study was done for all CLE patients who underwent surgery at Menoufia University Hospital. Perioperative data collected included demographic, clinical, and radiological findings, as well as operative and postoperative data.
Results: We included 30 neonates and infants who suffered from CLE between January 2013 and December 2020; the mean age was 111.43 ± 65.19 days, and 21 were males. All cases presented with respiratory distress; 19 had cyanosis, and 15 had recurrent pneumonia and fever. Plain chest x-ray and computed tomography (CT) revealed emphysema in all cases. Lobectomy was done in all cases; the mean age at surgery was 147.58 ± 81.49 days. Postoperative complications occurred in 5 patients, and 2 of them needed mechanical ventilation. The follow-up duration ranged from 3 months to 1 year (except 1 case lost to follow-up after 3 months), and all patients were doing well.
Conclusion: CLE is a rare bronchopulmonary malformation that requires a high index of clinical suspicion, especially in persistent and recurrent infantile respiratory distress. Chest CT is the most useful diagnostic modality. Early management of CLE improves outcome and prevents life-threatening complications. Surgical management is the treatment of choice in our center, without recorded mortality.

Published: June 2021

Objective: Ichthyoses are cornification disorders in which irregular epidermal separation and desquamation result in a faulty epidermal membrane. Harlequin ichthyosis (HI) was a rare and extreme type that led to neonatal death. It was caused by mutations in the ABCA12 gene, and the inheritance pattern is autosomal recessive. Case report: We present a case of HI that was diagnosed postnatally by clinical review. Extreme ectropion, eclabium, flattened nose, and primitive ears were discovered in the fetus. As a result of HI complications, the fetus died. Conclusion: The presence of HI was linked to a poor prognosis and a high mortality rate. Prenatal ultrasound and genetic analysis were critical for prenatal diagnosis of HI, but genetic modalities were not available and were prohibitively costly, despite their utility in providing appropriate prenatal therapy to families with HI babies. This case was recorded because of its rarity, as well as to draw attention to the connection between.

Published: June 2021

Objective: Determine the strengths and weakness of asymptomatic screening for COVID-19 in pregnant women. Analyze the results an percentage of positives in asyntomatic pregnant women. Design: Descriptive retrospective observational study. Setting: Mancha-Centro Hospital (Spain). Population: Asymptomatic pregnant women that get in to the hospital. Methods: Between the 12th of April and 1th of June 2020, all the asymptomatic pregnancies were screened with diagnostic test for SARS-CoV-2. Data collection was done by reviewing the medical records. Main outcomes measures: Clinical characteristics, management, treatment, and obstetric and neonatal outcomes. Results: A total of 117 patients were routinely screened using serological tests in maternal blood and PCR in nasopharyngeal exudate to detect COVID-19 patients. Of the 117 patients screened, 24 (20.5%) were positive in at least one of the two tests used for screening, of which 19 (79%) were asymptomatic and 5 (21%) symptomatic. Conclusions: We recommend universal screening of all pregnant woman for COVID-19 during the pandemic because of the limits of the symptomatic screening seen in the actual literature and the importance of transmission between asymptomatics patients.

Published: June 2021

Objective: Emergency Cesarean Section (ECS) improves maternal and neonatal outcomes but can be associated with complications including Surgical Site Infections (SSI). Prophylactic antibiotics reduce SSIs but inappropriate use increases antibiotic resistance. The study aim was to assess single versus multiple-dose antibiotic prophylaxis for SSI prevention in a limited-resource setting. Methods: All patients undergoing ECS in a rural district hospital were assessed for eligibility from 2015 to 2016. Participants were randomized, Group A received one dose of 2 g Ampicillin 15 to 60 minutes before skin incision and Group B received 2 g prior to skin incision with additional 1g every 8 hours over 72 hours. Participants were followed for 30 days, Demographic and clinical data were collected by chart review and patient phone interviews were performed on Days 3, 7, 15 and 30. Results: Three hundred and one participants were analyzed (147 in Group A; 154 in Group B). There were 8 surgical site infections in Group A and 4 in Group B (p=0.089). The overall prevalence of surgical site infections was lower than expected (4.00%). Most of SSIs cases were diagnosed on day 7 (66.6% of all cases of SSI) and only 22.2% of cases were diagnosed at discharge (day 3). Only 1 additional case was diagnosed at day 15. Conclusion: Compliance to infection control measures can reduce the rate of SSIs. There was no significant difference between the use of a single vs multiple doses of prophylactic antibiotics in our study but the SSI rate was low.

Upper pliocene diatom complexes and its significfnce to establish lower boundary of quarter (South of the Far East)
Authors:   Far East Geological Institute of the Far East Branch of the Russian Academy of Science, 159 100-Letiya Ave., Vladivostok 690022, Russia, Pushkar V.S.
Published: June 2021

An analysis of the evolutionary distribution of diatoms in the outcrops of the Late Cenozoic shows that, upon reaching the level of the Annensky Horizon (Gelazian stage), the extinct species disappear almost completely. A predominance of the alluvial type of sedimentogenesis and reduction in the lake basins areas are clearly registered for deposits of the diatom zone Aulacoseira praegranulata var. praeislandica f. praeislandica. A cooling in the Late Pliocene with the pronounced temperature minimum at the level about 2,58 million years is fairly bright reflected in the ecological structures of diatomic associations (upper complex): the benthic arcto- and north-boreal flora predominates. Of that time, a total absence of the pollen of the broad-leaved species is also characteristic and paleo-landscapes become close to the Eopleistocene ones. From this moment on, the coexistence and expansion of the polar ice sheets begin (transition of planet from the “Green house” mode to the “Ice house” mode) which determine the formation of the modern climatic system of the Earth which emphasizes the globality of the palaeoclimatic event. From the lithological point of view, the bottom of the red rocks strata of the Annensky Horizon corresponding to the Gelazian stage bottom (2,58 million years) coincides with this boundary in the southern Primorye. The age changes of the Quarter boundary to this chronostratigrahic level is well founded.
Unattached Cystoseira s. l. in the Black Sea: taxonomy of Gongolaria barbata f. repens comb. nov.
Authors:   M.G. Kholodny Institute of Botany, NAS of Ukraine, 2 Tereschenkivska Str., Kyiv 01601, Ukraine, Sadogurska S.S.
Published: June 2021

Brown algae of the genus Cystoseira s. l. are key species in the Mediterranean basin, including the Black Sea and the Sea of Azov. In addition to the typical attached forms of Cystoseira sensu lato (Ericaria crinita f. bosphorica (Sauvageau) S.S.Sadogurska, J.Neiva et A.Israel, and Gongolaria barbata (Stackhouse) Kuntze), an unattached form was previously described for the Black Sea. The taxonomic status of this taxon remained uncertain. According to the results of a comparative morphological analysis, it is shown that the Black Sea unattached samples belong to the species Gongolaria barbata. But unattached thalli, collected in the Dzharylhach Bay in the seagrass meadows of Zostera marina L., have morphological differences. Thalli are 30–50 cm long, light brown or yellow-brown; the holdfast is absent, the main axis is reduced or, if present, very short and thin (2–4 mm). Lateral branches are thin (2–3 mm), smooth; their length is 15–30 cm. The ultimate branches are filamentous, sometimes with oval-shaped aerocysts, single or arranged in chains. Receptacles are rarely present, spindle-shaped, 8–12 mm in length, without spines, but with a sterile mucron at the end. Therefore, a new nomenclature combination is proposed: Gongolaria barbata f. repens (A.D. Zinova & Kalugina) S.S. Sadogurska comb. nov. It is shown that the nomenclature combination Cystoseira concatenata f. repens A.D.Zinova & Kalugina is invalid. In addition, it is shown that the unattached Gongolaria barbata f. repens is not synonymous with the species Cystoseira aurantia Kützing sensu Orellana et al. (2019), which authors previouslyrearranged to the genus Cystoseira s.s. Analysis of phylogenetic trees from the works by different authors showed that unattached samples from the Mediterranean Sea and the Atlantic Ocean do not belong to the Gongolaria barbata clade and may be unattached forms of other species.

The quantitative (colony size, valve diameter and mantle height, the ratio of mantle height to valve diameter, number of areola rows and areolae in 10 µm on the mantle, ring-shaped diaphragm size) and qualitative (short pointed spines, areolae arrangement on the valve face and the mantle) morphological characteristics correspond to the diagnosis of A. pusilla (F.Meister) A.Tuji & A.Houki, a new species for the flora of Ukraine. In the analyzed material, minimum values of the mantle height and the height/diameter ratio are lower than in the published data.
SOIL RESOURCES OF UKRAINE: STATE, PROBLEMS AND STRATEGY OF SUSTAINABLE MANAGEMENT
Authors: Baliuk S.A. , Kucher A.V. , Maksymenko N.V.
Published: June 2021

The purpose of this study is to propose the concept of a strategy for sustainable management of soil resources in Ukraine based on the analysis of the dynamics and current state of soils and their fertility. In this study, we used such main methods: analysis, synthesis, monographic, expert assessments, calculation-and-analytical, abstract-and-logic, cartographic. Despite the intensification of soil degradation (losses of humus and nutrients, especially phosphorus and potassium, erosional losses of the upper fertile layer, physical degradation of soils; acidification of soils, especially in the Polissya and in the Carpathian region; secondary alkalinization and salinization of irrigated soils), there is a reduction in funding for soil protection measures. The area of degraded and infertile soils in Ukraine is over 8 mln ha, and direct annual losses of income only from crop failure due to the main types of soil degradation reach about 33.6 bln UAH in the country as a whole. The novelty of the study is that the provisions on the strategy of sustainable management of soil resources of Ukraine were further developed, in particular, in terms of a holistic macroeconomic approach to the scale of soil degradation and its environmental-and-economic consequences, and a holistic solution through a set of strategic measures of soil fertility reproduction. One of the first attempts to substantiate the strategy of sustainable management of soil resources of Ukraine from the standpoint of an interdisciplinary approach, which provides for: improvement of legislative and regulatory support; improving information and institutional support; effective international cooperation; technological and financial support of sustainable soil management, as well as forecast economic, environmental and social effects of solving the problem of soil degradation. The practical value of the obtained results is that their application should help increase the efficiency and performance of sustainable management of soil resources and achieve land degradation neutrality in Ukraine.
GLOBAL INITIATIVE «4 PER 1000» AND POSSIBILITIES OF ITS IMPLEMENTATION IN UKRAINE
Authors: Pozniak Stepan , Hnatyshyn Maria
Published: June 2021

The goals and objectives of the «4 per 1000» international initiative are highlighted in the article. The idea of the initiative is to increase carbon sequestration in soil, thereby reducing its amount in the atmosphere. This would be one of the opportunities to counteract global warming, while simultaneously contributing to the improvement of soil productivity and thus to the increase in food production. Increased soil carbon sequestration underlies a number of sustainable development goals. Global carbon dioxide emissions are steadily increasing. In Ukraine, unlike in the world, CO2 emissions are steadily declining. However, such a reduction is primarily due to the country’s GDP decline rather than the introduction of measures to green the economy. The carbon intensity of Ukrainian GDP is one of the highest in the world. The implementation of the «4 per 1000» initiative in Ukraine can be one of the tools to curb the growth of carbon dioxide in the atmosphere and at the same time to increase the productivity of agricultural land and to green the economy.
DEVELOPMENT DIRECTIONS OF UKRAINE ACCORDING TO DIFFERENT GLOBALIZATION SCENARIOS
Authors: Dronova Olena , Nahornyi Tymofii
Published: June 2021

The paper identifies the features of participation of Ukraine in neoliberal globalization processes, as well as the course of the 2020-2021 Global hiatus related to the current world financial crisis, COVID-19 pandemic and the “great lockdown” as its consequence. Among others, the study methods include the analysis of relevant scientific publications, screening and content analysis of analytical sources, statistical reports and open media. The research goal is to forecast possible ways of socio-economic development of Ukraine after the COVID-19 crisis using the potential options of the global future proposed by A.T. Kearney (2016). Using SWOT analysis, the prospects for the development of Ukraine and its regions are detailed according to the four very different potential scenarios: globalization 3.0, polarization, islandization and commonization, that highlight the scientific novelty of the research. The most probable (symbiosis of globalization and polarization) and the most preferable (commonization) scenarios are determined. At the same time, a contribution to the international scientific discourse on the Global hiatus concept was made, as well as to the discussion on the importance of increasing the regulatory impact of state, in particular on social issues and environmental protection, and to the discourse on rejection of neoliberal fundamentalism with further transition to post-liberalism and alter-globalization.

Published: June 2021

The purpose of the study is to identify the peculiarities of the local econetwork of Vinnytsia for the sustainable urban development. Methods: field research (key, area and route), literary-cartographic, analytical-cartographic analysis, collecting and processing of statistical information, theoretical generalization and systematization of facts, analysis, abstraction, analogy, synthesis. Results. 30 key territories, which occupy 15.9% of the city area, are distinguished in the structure of Vinnytsia econetwork. According to the peculiarities of vegetation and modern landscapes, all key territories are grouped into the following groups: forest, forest-meadow, forest-swamp, pond, garden-park and cemetery. Forest key territories that correspond to the background landscapes in the past are predominant (81.7% of the area). Key territories are joined by two national and twenty five local ecological corridors, which cover 12% of the city area. River-valley ecocorridors prevail among them in area and length while street-road ecological corridors prevail in their quantity. Buffer areas, that cover 4.8% of the city’s territory, are designed around key territories and ecological corridors. Thirteen recovery territories, which occupy 0.9% of Vinnytsia area, are potential for increasing the area of key territories and ecocorridors in the future. In perspective, seven interactive elements, projected mainly by stream valleys, occupying 0.6% of the city territory, may pass into the category of ecocorridors. The novelty of the study is that for the first time: since the change of Vinnytsia’s borders in 2015, the city econetwork project has been developed; peculiarities of interactive elements and ecotechnical junctions are identified and specificated; peculiarities of the landscape complexes of the territory were taken into account while justifying the choice of structural elements of the econetwork.
INTANGIBLE NATURE USE: «INFORMAL SECTOR» IN ENVIRONMENTAL SCIENCES
Authors: Karasov O. , Chervanyov I.
Published: June 2021

The goal was to substantiate the concept of intangible nature use and review the methodological approaches to quantitative assessment of intangible natural resources. We reviewed a state-of-the-art body of knowledge in environmental protection and transformation of economic policy responding to the sustainable development goals. In this paper, we generalised a large research direction regarding relational values of nature – intangible nature use. This research direction has been increasingly recognised within the natural resources frameworks, as evident from the experience of intergovernmental (IPBES) and national initiatives, and a recent shift of global GDP’s structure towards intangible components. Such a research direction is fruitful in the context of reprioritisation of values of nature of industrial era towards informational industries to resolve the contradictions between the potentially endless economic growth (based on instrumental values of nature) and nature protection activities. For the first time, we demonstrate how the international academic community (using diverse terminology and methodological frameworks, and often indirectly), gradually constitutes a new research domain on intangible nature use. We also highlight the prospects for decision-making and implementation of sustainable development practises in Ukraine.

Transcatheter mitral valve repair with the MitraClip, a catheter-based percutaneous edge-to-edge repair technique to correct mitral regurgitation (MR), has been demonstrated in Western studies to be an effective and safe MR treatment strategy. However, randomised clinical trial data on its use in Asian-Pacific patients is limited. Hence, the Asian Pacific Society of Cardiology convened an expert panel to review the available literature on MitraClip and to develop consensus recommendations to guide clinicians in the region. The panel developed statements on the use of MitraClip for the management of degenerative MR, functional MR, and other less common indications, such as acute MR, dynamic MR, hypertrophic obstructive cardiomyopathy, and MR after failed surgical repair. Each statement was voted on by each panel member and consensus was reached when 80% of experts voted ‘agree’ or ‘neutral’. This consensus-building process resulted in 10 consensus recommendations to guide general cardiologists in the evaluation and management of patients in whom MitraClip treatment is being contemplated.
The effects of a four weeks combined resistance training programme on cricket bowling velocity
Authors: Taliep Mogammad Sharhidd , Maker Rifqah
Published: June 2021

Background: Despite the importance of resistance training for cricket pace bowlers, there is limited research displaying meaningful improvements in ball release velocity following resistance training.

Objectives: The study aimed at investigating the effects of a four weeks combined resistance training programme on ball release velocity in club cricket pace bowlers.

Methods: Eighteen adult male club level pace bowlers were allocated into a combined resistance training (CRT) group or a traditional cricket training (TR) group. The CRT group (n=9) performed two training sessions a week for four weeks, consisting of a combination of core and lower body strength exercises, plyometric exercises, and weighted implement training. The TR group (n=9) did no resistance training and only bowled with regular weighted cricket balls. Pre- testing/post-testing variables were ball release velocity, bowling accuracy, and upper and lower body neuromuscular performance.

Results: The CRT group significantly increased their ball release velocity by six percent (5.1 km·h-1), effect size (ES) =0.65, p<0.001) after four weeks of training, while there was no significant difference in the TR group (0.00 km·h-1, ES=0.0, p=0.674). There was no statistically significant difference in the bowling accuracy and lower body neuromuscular performance for both groups and the upper body neuromuscular performance for the CRT group.

Conclusion: This study provides evidence of a combined resistance training programme that can be used to improve bowling velocity in cricket pace bowlers. This increase in ball velocity was not related to any of the neuromuscular performance variables measured.

What properties of non-electrolyte solutions does a DNA molecule feel?
Authors:   Frumkin Institute of Physical Chemistry and Electrochemistry of RAS, Malenkov George G.
Published: June 2021

As early as in 1953 it was reported that at low relative humidity of the atmosphere (about 70 %) DNA films were in A-form, while at higher humidity (more than 80%) they were in B-form. Relative humidity of the atmosphere corresponds to the water activity in the system. It was found in the beginning of the 70th that DNA transfers to the A-form when non-electrolytes, such as monoatomic alcohols, dioxane, tetrahydrofurane were added to water. It was reasonable to suppose that B to A transition of DNA occurs in the non-electrolyte solutions at the same values af water activity as in the moist atmosphere. This prediction was borne out. But in water solutions of very polar non-electrolytes such as methanol and ethylene glycol B to A DNA does not occur even at very low water activity values. It was supposed that A form of DNA can arise only in the medium with sufficiently low polarity. We used hyperfine splitting constant (A) of a nitroxide spin label determined from the EPR spectra as a measure of the liquid solvent polarity. It was found that DNA transition into B form occurs when A reached a certain value. Polarity of methanol and ethylene glycol is much higher than that of the solutions in which B to A DNA transition takes place. This transition also occurs in water solutions of trifluoroethanol. But in these solutions the transition takes place at hyperfine splitting values, which are much greater than in other non-electrolyte solutions. Water activity in the zone of B-A DNA transition in trifluoroethanol solutions does not correspond water activity which was calculated for other nob-electrolyte solutions in which B-A transition is observed.

Autocorrelation function of the particle velocity Z(t) is calculated using the molecular dynamics method in the models of liquid argon and water. The large size of the models (more than a hundred thousand particles) allowed us to trace these functions up to 50 picoseconds in argon and up to 10 picoseconds in water, and to achieve a calculation accuracy sufficient for analytical analysis of their shape. The difference in the determination of the self-diffusion coefficient using Einstein's law and the integral of Z(t) (Green-Kubo integral) is analyzed and it is shown to be 3% at best when t is of the order of several picoseconds. The asymptote of the function Z(t) in argon is close to the power law αt–3/2 predicted by hydrodynamics, but with an amplitude that depends on the time interval under consideration. In water, the asymptote of Z(t) has nothing in common with that in argon: it has α < 0 and the exponent is close to -5/2, and not to -3/2.

The monoethanolamine (MEA)-water system has been studied by IR spectroscopy and quantum-chemical calculations (DFT B3LYP). It was found that spatial networks both of water and MEA are continuously rearranging depending on the content of the system components. Water molecules are embedded into the net of MEA, and molecules of MEA into the water net, thereby forming a mixed network of hydrogen bonds.

The work is devoted to the comparative characteristics of the salting-in –salting-out effect of potassium formate, nitrate and perchlorate on the binary liquid water + n-butoxyethanol system with a closed delamination region in a temperature range of 10–150°C. The introduction of potassium formate or potassium nitrate into the mixtures of the critical composition of the binary water + n-butoxyethanol system leads to a decrease in the LCST (lower critical solution temperature) and an increase in the UCST (upper critical solution temperature) of this system, while the addition of potassium perchlorate leads to an increase in the LCST and a decrease in the UCST. For three ternary systems potassium salt + water + n-butoxyethanol, the distribution coefficients of n-butoxyethanol between the aqueous and organic phases of the monotectic state were calculated for several temperatures. It has been found that the distribution coefficient increases with temperature in each system. It has been established that potassium formate and potassium nitrate have a salting-out effect, the former having a particularly strong one. Potassium perchlorate at low concentrations and relatively low temperatures is characterized by a salting-in effect, which turns into a weak salting-out effect at higher temperatures. The results obtained can be used to develop practical recommendations for carrying out selective extraction of organic solvents and extractive crystallization of salts.
