“Smart Harlequin” in the Avant-garde and Modern Ukrainian Theatre
Authors: Ганна Веселовська
Published: June 2020

The author is focusing on the term “Smart Harlequin” introduced by outstanding Ukrainian theatre director Les Kurbas. By this term Kurbas defined a new type of intellectual, a super-expressive, easy-going, and psychologically flexible actor capable to cope with tasks facing the art of avant-garde. According to Kurbas, only an educated actor-intellectual could be a full-fledged participant to the theatre art and social processes. An active creator ofspectacles, Smart Harlequin would transform on stage to become a primary carrier of the intellectual principle, as opposed to underlying the emotionality of the scenic environment. Besides, in the avant-garde Smart Harlequin would often assume the function of drama playwright, author of the text.Forms of the modern theatre—such as new drama, verbatim and devised theatre—normally combine in one person both an author and a performer, whom any actor-intellectual actually is and whose method ofscenic existence was foreseen by Les Kurbas. In front ofspectators, Smart Harlequin ofthe 21st century emerges as a researcher inviting the audience to think over problems the theatre selects for social actualisation through play situations. As a rule, that actor-researcher tries to solve the problem in several ways in an improvisational style, while clearly demonstrating his or her attitude to it. Aside from purely artistic tasks, the avant-garde would assign Smart Harlequin with a good many non-artistic ones, such as being an active creator of the new social environment and catalyst ofsocial processes.

The article explores the cultural, sociological etc. aspects ofreflections of the image of Rodolfo Valentino, legendary American actor of the 1920 s., in Ukrainian and foreign literature of the 20th century, from Irina Vilde and Yaroslav Galan to Aldous Huxley and Julio Cortazar. Velentino’s influence on the viewers and culture in general was so profound during his lifetime that even official Soviet propaganda could not diminish his popularity. Yet, the following generations developed rather ludicrous image of Valentino, treating him with depreciation and distaste
Principles of Functional Classification of Music in Cinema
Authors: Поліна Харченко
Published: June 2020

The article deals with the basic principles of the functional classification of music in contemporary cinema, with the use of new technologies in the process of creating music for movies, and innovations introduced by modern film composers. The basic principles of functional classification of music in modern cinema should be considered with regard to systemic, socio-cultural approaches, to the latest developments in cinema studies and musicology, as well as comparative-historical and logical-analytical methods. The main principles of sound and image interaction in cinema are established, being: mutual reinforcement and counterpoint between sound and visual components in film drama, consistency and logic in the development of the storyline and unfolding of the concept of the film, harmonization or intensifying the interaction between the inner sense and perception of this sense by the recipients. The main functions of music in cinema are defined: managing emotions; intensifying artistic communication; creation of intertextuality within the work; “background” support of the main plot line; combining the other components of the structure of the screenplay, including parts of the storyline. Nowadays, the following basic models of interaction of music with a plot function in cinema: illustrative, contrast, synchronous, communicative and structural. The basic principles and functions of music in modern cinema, caused by the development of compositional practice and changes in filmmaking technologies, are substantiated. The functions of music in cinema determine the certain models of interaction sound and visuals on screen.

Abstract. With the increased use of horses in sports of various modalities, sports medicine has been increasingly studied so as to have a better understanding of what happens to these animals during the proposed activity. Fitness and training are essential for proper performance and performance in equestrian events, being an important role in the routine of these animals. The aim of the present study was to evaluate changes in serum biochemistry (creatine kinase, glucose and lactate) in seven Mangalarga Marchador (MM) horses submitted to gait training. Three collections were performed within 60 days, divided into D0, D30 and D60 with the animals at rest and after exercise. The results were: regarding pre-training, mean CK values were obtained in 152.2 ± 50.9 IU/L, 277.2 ± 194.4 IU/L and 301.9 ± 125, glucose in 92. 3 ± 11.4 mg/dL, 97.0 ± 10.3 mg/dL and 87.6 ± 10.3 mg/dL, and lactate at 2.4 ± 0.5 mmol/L, 2.0 ± 0.4 mmol/L and 2.2 ± 0.6 mmol/L, respectively at D0, D30 and D60. Post-training mean CK values were 187.9 ± 25.5 IU/L, 358.6 ± 244.1 IU/L and 307.6 ± 116 IU/L, glucose 97.3 ± 11, 4 mg/dL, 119 ± 16.8 mg/dL and 108.6 ± 28 mg/dL and lactate at 3.3 ± 0.9 mmol/L, 3.6 ± 1.2 mmol/L and 4 ± 1 mmol/L at D0, D30 and D60 respectively. No significant increase in CK was observed under the type of exercise imposed, increasing the powders by 14.4% in the average of all collections. Of the lactated results, we had a significant increase in the pre-training average compared to the post in 39.4%. Already glucose was not significant having increased after 14.8% in the average days of the present study. We can observe that the change in glycemia was relatively different from lactate levels demonstrating the use of the aerobic route.

Published: June 2020

Canine Monocytic Ehrlichiosis is a disease caused by the obligate intracytoplasmic bacterium Erlichia canis, having as vector the tick of the dogs Rhipicephalus sanguineus. It has a clinical course based on acute, subclinical and chronic presentations, varying the intensity of the signs, being able to attend with anemia, depression and in chronic cases depletion. It has a worldwide distribution, but even with the vector intensely present in Rio Grande do Sul, the number of scientific clinical reports are very low. The objective of this work was to report a case of Canine Monocytic Ehrlichiosis in a dog in the state of Rio Grande do Sul. A female, 5-year-old, atopic, Shih Tzu was treated with complaint of lack of appetite and apathy. The hemogram showed intense macrocytic hypochromic anemia. The smear was positive for Erlichia sp. A treatment with doxycycline was instituted with subsequent stabilization of the condition. Three months later, the animal returned to the same symptomatology of apathy and lack of appetite, being diagnosed with hyperchromic normocytic anemia and hematocrit of 5%. Immediate blood transfusion and a new treatment with doxycycline of 15 days were instituted, being an improvement of the picture after this period. This work underscored the importance of correct diagnosis and treatment as well as incorporating the scientific literature on Canine Monocytic Ehrlichiosis in Rio Grande do Sul.

Authors: Borges Ana
Published: June 2020

This work aimed to evaluate the percentage of water and the presence of residues in fresh honey, sold informally at the Guará I-DF fair. Collections and analyzes of 30 honey samples were made. The physical and chemical standards of the product were evaluated following the standards of current legislation. The percentage of H2O, bee parts, starch and pollen were analyzed. It was observed that 0.3% (1/30) of the samples showed a percentage of water in the product outside the established standards. Regarding the presence of bee parts, starch and pollen, all samples had at least one of the residues. The results showed that honey in natura is subject to several changes and the presence of insoluble materials that are not allowed by law to be present in the food, often making it unfit for consumption as it can cause damage to the health of the consumer if ingested. Research has shown that honey inspection activity is of fundamental importance in order to ensure that the food reaches the consumer's table with safety and ideal quality to avoid damage to public health and consumer fraud.

This work was conducted to evaluate the influence of the packaging method (in a tray wrapped in film paper or vacuum) on pH, color, texture, lipid oxidation, and antioxidant activity of beef before aging (day 1) and aging for 3, 7 and 14 days. The samples of meat were obtained from 36 animals finished in feedlot for 84 days. After collection, Longissimus dorsi was filleted in 2.5 cm samples packed in a tray wrapped in film or vacuum for 3, 7 and 14 days. Meats in vacuum packaging showed lower pH (P < 0.001). The aging time reduced (P < 0.001) pH value of the meat in both methodologies. Cooking losses were higher (P < 0.001) for vacuum-packed meats and were reduced with aging time. The L* values were not changed (P > 0.05) by the packaging, but were reduced by aging. The values of a* were not altered (P > 0.05) by the packaging, but were increased by aging. The texture and lipid oxidation were not altered (P > 0.05) by the packaging, but the texture was improved by aging, while the lipid oxidation increased. The packaging and aging days had no effect (P > 0.05) on antioxidant activity of the meat as measured by three methodologies (ABTS, DPPH and FRAP).

Factors Influencing User Satisfaction with Information Systems: A Systematic Review
Authors: Kalankesh Leila R , Nasiry Zahra , Fein Rebecca , Damanabi Shahla
Published: June 2020

User satisfaction has been considered as the measure of information system effectiveness success. User satisfaction is difficult to define but is considered an evaluation construct. Globally health organizations, particularly hospitals, invest a huge amount of money on information system projects. If hospital information systems (HISs) are to be successful, factors influencing or related to user satisfaction should be taken into account at the time of designing, developing or adopting such systems. The current study aimed to provide a comprehensive review of factors related to user satisfaction with information systems. The researchers systematically searched PubMed, Science Direct, and IEEE electronic databases for articles published from January 1990 to June 2016. A search strategy was developed using a combination of the following keywords:  “model,” “user satisfaction,” “information system,” “measurement,” “instrument,” and “ tool.” Reported dimensions, factors, and their possible influence on user satisfaction with information systems were extracted from the studies wherever was possible. Overall factors influencing user satisfaction with information systems can be categorized in seven dimensions: Information quality, system quality, vendor support quality, system use, perceived usefulness, user characteristics, and organizational structure& management style. If all these factors are considered properly in the process of developing, designing, implementing, or purchasing information systems, the higher user satisfaction with the system will be likely. Otherwise, it would end up with unsatisfied users that will finally contribute to the system failure. [GMJ.2020;9:e1686]

Authors: ÇETİN Canan , DEDE Ezgi , ERYILMAZ Serdar
Published: June 2020

The aim of the study is to survey the influence of ethical leadership on work engagement and its dimenions. Furthermore, we examined the descriptive statistics, t- test, anova test, reliability, correlation and regression analysis. It is noted that this examination is based on a survey of humanitarian aid organizations and 1312 people working for humanitarian aid organizations in Turkey. Consequently, it is found that all established hypotheses are supported and they are positively related to each other. Ethical leadership has a significant effect on work engagement and its dimensions which are vigor, dedication and absorption. In addition to these results, the relationship between some demographic variables and ethical leadership and work engagement is also investigated. Employees who keep their business both at work and out of work are more dedicated and employees who keep their business only at work are more absorptive. Employees who don’t have much experience at work are more absorptive. Employees who are at the middle age group have greater sense of perceived ethical leadership and work engagement, more vigorous and absorptive. Employees whose ages are less than 30 and between the ages of 30 and 40 are more dedicated.

In an intensely competitive environment, the companies in the production sector fall behind as a result of not showing performance at desired levels, which and leads to companies leaving the sector. Particularly in terms of leadership, the trust of employees in the subordinate hierarchy of organizations, as well as their identification with the organization, should be managed with an accurate understanding. The aim of this study is to analyze the concepts of empowerment leadership and emotional intelligence, the trust of employees in the organization, and the relationships between them within an organization. When the data obtained through the study was analyzed, it was found that leadership and emotional intelligence had a positive effect in the formation of trust and organizational identity among employees. Within the scope of the study, surveys were conducted with 381 white-collar workers (administrative personnel) who work in the production sector. Analyzes were made using SPSS 25 and AMOS programs. In addition, sobel test and hayes process were performed in mediation variable analysis. After both confirmatory and explanatory factor analysis, as well as reliability analysis, correlation analysis and regression analysis were used.
Preoperative factors associated with adverse events during awake craniotomy: analysis of 609 consecutive cases
Authors: Takami Hirokazu , Khoshnood Nikki , Bernstein Mark
Published: June 2020

OBJECTIVE

Awake surgery is becoming more standard and widely practiced for neurosurgical cases, including but not limited to brain tumors. The optimal selection of patients who can tolerate awake surgery remains a challenge. The authors performed an updated cohort study, with particular attention to preoperative clinical and imaging characteristics that may have an impact on the viability of awake craniotomy in individual patients.

METHODS

The authors conducted a single-institution cohort study of 609 awake craniotomies performed in 562 patients. All craniotomies were performed by the same surgeon at Toronto Western Hospital during the period from 2006 to 2018. Analyses of preoperative clinical and imaging characteristics that may have an impact on the viability of awake craniotomy in individual patients were performed.

RESULTS

Twenty-one patients were recorded as having experienced intraoperative adverse events necessitating deeper sedation, which made the surgery no longer “awake.” In 2 of these patients, conversion to general anesthesia was performed. The adverse events included emotional intolerance of awake surgery (n = 13), air embolism (n = 3), generalized seizure (n = 4), and unexpected subarachnoid hemorrhage (n = 1). Preoperative cognitive decline, dysphasia, and low performance status, as indicated by the Karnofsky Performance Status (KPS) score, were significantly associated with emotional intolerance on univariate analysis. Only a preoperative KPS score < 70 was significantly associated with this event on multivariate analysis (p = 0.0057). Compared with patients who did not experience intraoperative adverse events, patients who did were more likely to undergo inpatient admission (p = 0.0004 for all cases; p = 0.0036 for cases originally planned as day surgery), longer hospital stay (p < 0.0001), and discharge to a location other than home (p = 0.032).

CONCLUSIONS

Preoperative physical status was found to be the most decisive factor in predicting whether patients can tolerate an awake craniotomy without complications, whereas older age and history of psychiatric treatment were not necessarily associated with adverse events. Patients who had intraoperative adverse events often had reduced chances of same-day discharge and discharge to home. Preoperative careful selection of patients who are most likely to tolerate the procedure is the key to success for awake surgery.

OBJECTIVE

Surgical decision-making and planning is a key factor in optimizing outcomes in adult spinal deformity (ASD). Minimally invasive spinal (MIS) strategies for ASD have been increasingly used as an option to decrease postoperative morbidity. This study analyzes factors involved in the selection of either a traditional open approach or a minimally invasive approach to treat ASD in a prospective, nonrandomized multicenter trial. All centers had at least 5 years of experience in minimally invasive techniques for ASD.

METHODS

The study enrolled 268 patients, of whom 120 underwent open surgery and 148 underwent MIS surgery. Inclusion criteria included age ≥ 18 years, and at least one of the following criteria: coronal curve (CC) ≥ 20°, sagittal vertical axis (SVA) > 5 cm, pelvic tilt (PT) > 25°, or thoracic kyphosis (TK) > 60°. Surgical approach selection was made at the discretion of the operating surgeon. Preoperative significant differences were included in a multivariate logistic regression analysis to determine odds ratios (ORs) for approach selection.

RESULTS

Significant preoperative differences (p < 0.05) between open and MIS groups were noted for age (61.9 vs 66.7 years), numerical rating scale (NRS) back pain score (7.8 vs 7), CC (36° vs 26.1°), PT (26.4° vs 23°), T1 pelvic angle (TPA; 25.8° vs 21.7°), and pelvic incidence–lumbar lordosis (PI-LL; 19.6° vs 14.9°). No significant differences in BMI (29 vs 28.5 kg/m2), NRS leg pain score (5.2 vs 5.7), Oswestry Disability Index (48.4 vs 47.2), Scoliosis Research Society 22-item questionnaire score (2.7 vs 2.8), PI (58.3° vs 57.1°), LL (38.9° vs 42.3°), or SVA (73.8 mm vs 60.3 mm) were found. Multivariate analysis found that age (OR 1.05, p = 0.002), VAS back pain score (OR 1.21, p = 0.016), CC (OR 1.03, p < 0.001), decompression (OR 4.35, p < 0.001), and TPA (OR 1.09, p = 0.023) were significant factors in approach selection.

CONCLUSIONS

Increasing age was the primary driver for selecting MIS surgery. Conversely, increasingly severe deformities and the need for open decompression were the main factors influencing the selection of traditional open surgery. As experience with MIS surgery continues to accumulate, future longitudinal evaluation will reveal if more experience, use of specialized treatment algorithms, refinement of techniques, and technology will expand surgeon adoption of MIS techniques for adult spinal deformity.
Anterior lumbar compared to oblique lumbar interbody approaches for multilevel fusions to the sacrum in adults with spinal deformity and degeneration

Published: June 2020

OBJECTIVE

In adult spinal deformity and degenerative conditions of the spine, interbody fusion to the sacrum often is performed to enhance arthrodesis, induce lordosis, and alleviate stenosis. Anterior lumbar interbody fusion (ALIF) has traditionally been performed, but minimally invasive oblique lumbar interbody fusion (OLIF) may or may not cause less morbidity because less retraction of the abdominal viscera is required. The authors evaluated whether there was a difference between the results of ALIF and OLIF in multilevel anterior or lateral interbody fusion to the sacrum.

METHODS

Patients from 2013 to 2018 who underwent multilevel ALIF or OLIF to the sacrum were retrospectively studied. Inclusion criteria were adult spinal deformity or degenerative pathology and multilevel ALIF or OLIF to the sacrum. Demographic, implant, perioperative, and radiographic variables were collected. Statistical calculations were performed for significant differences.

RESULTS

Data from a total of 127 patients were analyzed (66 OLIF patients and 61 ALIF patients). The mean follow-up times were 27.21 (ALIF) and 24.11 (OLIF) months. The mean surgical time was 251.48 minutes for ALIF patients and 234.48 minutes for OLIF patients (p = 0.154). The mean hospital stay was 7.79 days for ALIF patients and 7.02 days for OLIF patients (p = 0.159). The mean time to being able to eat solid food was 4.03 days for ALIF patients and 1.30 days for OLIF patients (p < 0.001). After excluding patients who had undergone L5–S1 posterior column osteotomy, 54 ALIF patients and 41 OLIF patients were analyzed for L5–S1 radiographic changes. The mean cage height was 14.94 mm for ALIF patients and 13.56 mm for OLIF patients (p = 0.001), and the mean cage lordosis was 15.87° in the ALIF group and 16.81° in the OLIF group (p = 0.278). The mean increases in anterior disc height were 7.34 mm and 4.72 mm for the ALIF and OLIF groups, respectively (p = 0.001), and the mean increases in posterior disc height were 3.35 mm and 1.24 mm (p < 0.001), respectively. The mean change in L5–S1 lordosis was 4.33° for ALIF patients and 4.59° for OLIF patients (p = 0.829).

CONCLUSIONS

Patients who underwent multilevel OLIF and ALIF to the sacrum had comparable operative times. OLIF was associated with a quicker ileus recovery and less blood loss. At L5–S1, ALIF allowed larger cages to be placed, resulting in a greater disc height change, but there was no significant difference in L5–S1 segmental lordosis.
The blood coagulation system of rats under the influence of laser radiation in different time parameters
Authors: Ketsa Oksana , Marchenko Mykhailo , Bodnarjuk Nadiia
Published: June 2020

The influence of different terms of laser irradiation on vascular-platelet and coagulation units of blood coagulation system is investigated. The rats were irradiated with a laser diode in the red spectrum (650 nm) with a power of 50 mW. Rats were divided into two groups: group I - rats, which were irradiated daily for 2 minutes; group II - rats, which were irradiated daily for 4 minutes. Euthanasia of animals was performed on the 7th and 14th days after the onset of irradiation. For the study of the blood coagulation system of rats used biochemical coagulogram with the analysis of the following indicators - the content of fibrinogen, thrombin and prothrombin time, activated partial thromboplastin time (APTT), platelet count. The content of lymphocytes and erythrocyte sedimentation rate were determined also. In the work used blood plasma with sodium citrate. It has been found that daily four-minute laser irradiation in the abdominal area for two weeks leads to a decrease in the concentration of factor I blood clotting (fibrinogen) and an increase in thrombin time. At the same time, prolongation of prothrombin time and APTT was detected, indicating a deficiency of other factors of blood coagulation - II, V, VII-XII, and the presence of anticoagulant status, which may be associated with inhibition of the internal pathway of clotting. Thrombocytopenia is probably caused by the increased destruction of platelets or their insufficient formation as a result of dysfunction of hematopoietic organs. The two-minute effect of laser irradiation does not affect the clinical and biochemical parameters of the blood coagulation system of rats after a weekly daily action of the laser diode. Two weeks irradiation is accompanied by processes of hypocoagulation, as evidenced by a decrease in fibrinogen levels, platelet counts, and a simultaneous increase in APTT, thrombin and prothrombin time.
Organization of 5S rDNA of field maple (Acer campestre L.)
Authors: Іshchenko Olha , Panchuk Irina , Volkov Roman
Published: June 2020

In recent decades, molecular methods have been widely used to study plant speciation and taxonomy. The 5S rDNA, which belongs to the class of repeated sequences present in the genomes of all eukaryotes, represents a convenient model for studying the patterns of molecular evolution in plants. Each of 5S rDNA repeated units consist of a coding region and an intergenic spacer (IGS). The coding sequence is highly conserved in evolution, whereas the IGS can differ between related species and even between populations of the same species. The molecular organization of the 5S rDNA in representatives of genus Acer is still poorly explored. Accordingly, the aim of the study was to investigate the organization and variability of the 5S rDNA of the European species Acer campestre. Analysis of the obtained sequences showed, that the 5S rDNA clones of A. campestre are identical. The level of IGS sequence similarity between A. сampestre and A. platanoides amounts to 96.1%, whereas the similarity between these species and A. pseudoplatanus is lower, namely – 81,9–82,4%. Therefore, A. campestre and A. platanoides can be considered as closely related species. Only one class of 5S rDNA repeats is present in the genome of A. сampestre. The potential external elements of the RNA polymerase III promoter localized in the IGS differ from those described early for representatives of other families of angiosperms.
Productivity of green algae Dunaliella viridis Teodoresco at different amount of NaCl in the culture medium
Authors: Cheban Larysa , Trebysh Yuliia , Marchenko Mykhailo
Published: June 2020

The study is devoted to an investigation of the effect of NaCl concentration on the productivity of halophilic algae D. viridis. This is a single-celled photosynthetic green algae that lack a cell wall. D. viridis can grow at extremely high salinities and light intensities. Salt was added to the culture medium at a concentration of 0.1 M, 0,5 M, 1,5 M and 2 M. The growth pattern of D. viridis depends on the concentration of NaCl in the culture medium. It was shown that such culture is resistant to high concentrations of salt. In the classical culture medium Artari, D. viridis grows very rapidly and accumulates maximum biomass at the end of the exponential growth phase. Changes in salt concentration of classical culture medium Artari changes the biomass growth rate. The maximal accumulation of biomass is observed on 12-th day of D. viridis growing at 1.5 M NaCl. The use of 0.1 M or 0.5 M salt slows the growth of algae culture. In the cultivation of D. viridis under conditions of varying availability of NaCl marked slight fluctuations in the pH level. However, they were not critical for this alga. Changing the amount of NaCl help to predict an increase in productivity of algae lipids or proteins. The biomass of D. viridis is characterized of maximal protein content while cultivating at 0.5 M or 1.5 M NaCl. The highest amount of lipids and carotenoids was observed in algae cultivated at 2 M salt. But they were also characteristic of the control environment. By the amount of biomass accumulated, protein content, levels of lipids and pigments, the Artari medium with 1.5 M NaCl is optimal for the production of D. viridis biomass with a higher protein content. Such D. viridis biomass can be used as a feed in aquaculture.

Published: June 2020

It was discovered that flora of the National Natural Park “Hutsulshchyna” consists of 836 species of higher vascular plants which belong to 411 generas, 111 families and 5 divisions. Magnoliophyta dominate -94,3%, Magnoliopsida to Liliopsida ratio is 1:3 which is characteristic of Central Europe flora. Ten leading families of the NNP “Hutsulshchyna” include 209 genera and 455 divisions, the rest 45,4% of divisions belong to 102 families. The flora ratio is 1:3,7:7,5; an average number of divisions in a genus is 2,0; the number of genera in a family is 3,7. The NNP’s flora ratio is close to Central Europe’s. Asteraceae and Poaceae families take the leading position in ranges of flora. Rosacea family is in the third position, which indicates typical Central European flora. The ratio of Asreraceae to Lamiaceae is 3,0, which is typical of Boreal and Nemoral areas flora. (2,5-3,8). The ratio of Asteraceae to Fabaceae in the NNP “Hutsulshchyna” is 2,2. The transition from Boreal flora area to Mediterranean can be demonstrated by the range the Karpatskyi NNP - NNP “Hutsulshchyna” - NNP “Vyzhnytskyi”, which corresponds to their location from north-east to south-west and to transition from mountainous to plain flora types. So our systematic analysis confirms that the Park’s flora is typically Central European with distinct Boreal traits. We present comparative characteristics of the flora of NNP “Hutsulshchyna” and the adjacent NNP “Vyzhnytskyi” and Karpatskyi NNP. The comparison of the indices of systematic structure of the investigated flora with floras of Boreal and Middle European regions is shown that more than half of the main indicators of the NNP "Hutsulshchina" coincide with the indicators in the flora of Boreal region.
The use of tropical and subtropical plants in the landscaping of metropolis

Published: June 2020

One of the promising areas of landscaping is container. The use of plants in containers in the central part of the city will create landscaping in areas where trees and shrubs cannot be planted directly into the soil. Perspective, in this regard, is the use in landscaping in the frost-free period of tropical and subtropical plants. This method does not solve the problem as a whole, but it can be a great original addition. The aim of this work was to analyze the participation of tropicogenic flora plants in the landscaping of the city of Kryvyi Rih and to identify perspectives for greening of metropolitan species from the collection of tropical and subtropical plants of the Kryvyi Rog Botanical Garden of the NAS of Ukraine. Surveying of the city's greening showed that the use of subtropical and tropical plants as a container container during the warm period is quite limited, and the single facts of their use in containers are revealed. For these purposes, plants of Chamaerops humilis L., Agave americana L., Brugmansia suaveolens (Humb. Et Bonpl. Ex Wild.), Chlorophytum comosum (Thunb.) Baker., Chlorophytum comosum 'Variegatum', Nerium oleander L. varieties were used. In the presence of extremely rich collections of tropical and subtropical plants in the botanical gardens of Ukraine, there is an opportunity to significantly expand this list. The Kryvyi Rih Botanical Gardens protected soil collection has 988 taxa. Based on study of plant biology, the collection identifies and identifies species that are appropriate for landscaping metropolitan areas by planting them in portable containers, and some of them directly into the soil as accent plants. When selecting plants for landscaping in the open ground it is important to take into account the features of their stay in the winter in the halls or greenhouses (temperature and light modes).
Pedogeochemical barriers of heavy metals’migration distribution in chernozems soil profile at Kryvorizhzhya
Authors: Savosko Vasyl'
Published: June 2020

The basic regularities of the distribution of heavy metals’migration pedogeochemical barriers in soil profile of the chernozems ordinary and southern at Kryvy Rih mining and metallurgical regions were analyzed. It was pointed out that heavy metals’migration pedogeochemical barriers is a part of the soil horizon or soil profile, where there is a significant concentration of individual chemical elements as a consequence of the substitution-reaction phenomenon. Pedogeochemical barriers are classified into five types: mechanical, physical, physical and chemical, chemical and biological. The spread of pedogeochemical barriers in Chernozem is determined by the peculiarities of distribution of their leading components: humus, clay, colloids, and carbonates. According to the coefficients of concentration, the maximum content Fe and Mn in chernozems ordinary and Fe, Mn, Zn and Cu in chernozems southern was found in the surface humus-accumulative horizon. In addition, the action of heavy metals’migration pedogeochemical barriers can be considered as leaching of metals such as: Pb and Cd, which is due to these metals a-biofilm. In chernozems ordinary, the most intensively pedogeochemical barriers act in the humus transitional and humus cumulative horizons. In chernozems southern, the pedogeochemical barriers act most intensively in the humus accumulative horizon.
Professor Veit Graber is the founder of the Zoological Institute at Franz Josef University in Chernivtsi. (Biographical Story, to the 175 anniversary of his birth)
Authors: Tkebuchava Iryna Tkebuchava , Andrjuschenko Tatiana
Published: June 2020

The article is devoted to the Veit Graber (1844-1892) – first director of the Zoological Institute and Zoological Museum of the University of Chernivtsi. The well-known Austrian zoologist worked at the Chernivtsi University for 16 years (in 1876-1892), twice as the dean of the Faculty of Philosophy (in 1879-80 and 1886-87 academic years), and he was rector of the university in 1886-87. Graber's scientific heritage is about 70 printed works (articles, books, monographs, tractates), most of which describe the anatomy, sensory organs, embryology, phylogeny of insects and other invertebrates (Annelida, Polychaeta; Echinodermata; Arachnida; Myriapoda). Some of his exhibits collected in scientific expeditions (in the Austrian Alps, to the Mediterranean, in Trieste, Naples) are still stored in the zoological collections of the Nature Museum Chernivtsi National University.
Experimental investigations for the modelling of anhydritic swelling claystones
Authors: Wanninger (-Huber) Tara
Published: June 2020

Anhydritic claystones are highly problematic for underground construction because of their swelling ability: When the rock comes into contact with water, the rock volume expands due to swelling of both clay as well as anhydrite. When the expansion is restricted, e.g., by an invert arch in tunneling, the swelling rocks can exert high pressures on the lining and damage the structure. The swelling behavior of purely argillaceous rock (containing solely swelling clays and no anhydrite) can be attributed mainly to osmotic processes and is well understood for the conceptual design of tunnels, as opposed to the swelling of anhydrite, where considerable knowledge gaps exist.
Swelling of anhydrite is caused by chemical processes: The anhydrite dissolves when it comes into contact with water, and from the dissolved ions in the pore water gypsum precipitates. The volume of gypsum is greater than that of anhydrite by 61%. During Anhydrite to Gypsum Transformation (hereafter denoted as AGT) the rock mass expands and the pore volume can also increase, for example due to cracking of the rock induced by the pressure exerted by the growing crystals upon a rigid rock structure ("crystallization pressure").
This PhD thesis seeks to establish a better understanding and quantification of the coupled chemomechanical swelling processes due to AGT and creates a basis for developing chemo-mechanical models of the swelling of anhydritic claystones.
The findings from the experiments verified kinetic models and assumptions related to AGT. Moreover, the systematic experimental investigations regarding the swelling behavior of anhydrite give an indication of a stress-strain relationship which can be implemented and used as a fundamental basis for future modelling of swelling due to AGT. This is necessary for practicing engineers in order to design underground structures in anhydritic rock. Furthermore, it was shown that the swelling due to anhydrite and clay can be de-coupled by varying the testing temperatures, which changes the equilibrium concentrations.
Politikevaluation und Evaluationspolitik
Authors: Straßheim Holger , Schwab Oliver
Published: June 2020

Es gibt inzwischen kaum ein Politikfeld, in dem Evaluierung nicht in irgendeiner Form praktiziert wird. Die Evaluierungslandschaft zeichnet sich dabei sowohl durch Vereinheitlichungs- als auch Pluralisierungstendenzen aus. In unterschiedlichen Evaluierungsarrangements kommen spezifische Akteure, Praktiken und Standards zusammen. Zudem handelt es sich nicht um politikfreie Räume. Vielmehr sind diese „Varieties of Evaluation“ selbst Ausgangspunkt, Medium und Gegenstand von Politiken der Evaluation, also der Auseinandersetzung um legitime Formen der Politikbewertung Der Themenschwerpunkt unternimmt eine Bestandsaufnahme, indem er die Formen und Folgen von Politikevaluation als Evaluationspolitik sowohl in theoretisch wie empirisch ausgerichteten Beiträgen nachzeichnet. In interdisziplinärer Absicht werden aktuelle Befunde der Politik- und Verwaltungswissenschaft, der Governance- und Policy-Analyse, der politischen Soziologie und der Soziologie der Bewertung vorgestellt.
Institutionalisierung der Evaluation in den politischen Systemen Europas. Eine vergleichende Analyse
Authors: Meyer Wolfgang , Stockmann Reinhard
Published: June 2020

Der Beitrag präsentiert die ersten vergleichenden Ergebnisse eines weltweiten Forschungsprojekts zur Institutionalisierung der Evaluation. Mehr als 30 Autorinnen und Autoren haben sich mit der Situation in 16 Ländern Europas beschäftigt und diese anhand eines einheitlichen Analyseleitfadens untersucht. Bei der Betrachtung der Integration von Evaluation innerhalb des politischen Systems standen drei Aspekte im Vordergrund: Die formalen Verankerungen in der Legislative (z. B. in Form von Gesetzen und Verordnungen) und in der Exekutive (z. B. der Evaluationspraxis in verschiedenen Politikfeldern, Ministerien und Behörden) sowie die Nutzung der Evaluationsergebnisse für evidence-based policies. Es handelt sich um die erste umfassende systematische Bestandsaufnahme der Institutionalisierung von Evaluation in den politischen Systemen Europas. Herausgearbeitet werden die Gemeinsamkeiten und Unterschiede sowie die unterschiedlichen Einflussfaktoren auf die nationalen Institutionalisierungsprozesse. In die Betrachtung gehen z. B. Spezifika nationaler politischer Systeme, die Einflüsse transnationaler Organisationen (insbesondere der Europäischen Union), die sektoralen Besonderheiten und ihre Leitfunktionen sowie die Rolle der Zivilgesellschaft mit ein.

Formen der Evaluierung experimenteller Politikgestaltung
Authors: Kaps Petra
Published: June 2020

Die Reformen der Arbeitsmarktpolitik der letzten 20 Jahre wurden von einer Reihe politischer Experimente begleitet, die jeweils anlassbezogen evaluiert wurden. An drei Beispielen – den Kombilohn- Experimenten, Experimenten zur Pauschalierung einmaliger Leistungen in der Sozialhilfe und am Wettbewerb zwischen Optionskommunen und Arbeitsagenturen in Arbeitsgemeinschaften mit den Kommunen – werden Evaluierungsarrangements als Kombinationen von Evaluierungsgegenständen, Evaluierungsaufträgen und Evaluierungspraktiken untersucht. Dabei wird nach Unterschieden und Gemeinsamkeiten zwischen diesen Arrangements, nach „varieties of evaluation“ (Schwab, 2017, S. 201), gefragt. Und es wird der Zusammenhang zwischen den institutionellen Rahmenbedingungen innerhalb des politisch-administrativen Systems und der Gestaltung dieser Evaluierungsarrangements untersucht. Dabei wird auch skizziert, welcher „politische Gehalt von Evaluierungsprozessen“ (ebd., S. 212) im Vergleich der Beispiele sichtbar wird.
