Authors: Szelényi Zoltán , Győri Dorottya , Boldizsár Szabolcs , Kovács Levente , Répási Attila , Molnár László , Szenci Ottó
Published: March 2019

The aim of this study was to examine the effect of twin pregnancy, fetal laterality, the number of corpora lutea (CL) and cavitary CL on pregnancy losses in Holstein-Friesian cows with a positive pregnancy diagnosis based on ultrasonography between days 29–42 after AI. Pregnancy was confirmed by transrectal palpation between days 57–70 after AI and at the time of drying-off as well. Twin pregnancy rate was 8.4% at the time of the early pregnancy examination. Pregnancy loss did not differ between singleton- and twin-carrying animals either between days 57–70 of gestation or at drying-off. More losses occurred in singletons between days 29–42 and 57–70 in cows with cavitary than in cows with noncavitary CL (12.1% vs. 3.6%; P < 0.05) and in cows with double CL than in cows with single CL (7.3% vs. 3.6% %; P < 0.05). Between days 57–70 of gestation and drying-off this difference was still significant (20.7% vs. 3.7%; P < 0.001), while it was non-significant between cows with one CL (5.7%) vs. double CL (3.7%). Cavity occurrence was not affected by hormone therapy prior to AI (either PGF2α or OvSynch; 4.4% vs. 5.4%, respectively); however, the number of CL was reduced by the treatments (11.6 vs. 19.6%; P < 0.0005). In twin pregnancies there was no difference in the pregnancy losses between bilateral and unilateral pregnancies at any time point. The length of gestation was 278.2 ± 10.5 (singleton) and 267.4 ± 31.2 (twin) days, respectively (P < 0.01). The stillbirth ratio was higher in twin carriers than in singleton carriers (19.5% vs. 5.3%; P < 0.001).

Published: March 2019

This article presents a hybrid numerical scheme for a class of linear and nonlinear singularly perturbed convection delay problems on piecewise uniform. The proposed hybrid numerical scheme comprises with the tension spline scheme in the boundary layer region and the midpoint approximation in the outer region on piecewise uniform mesh. Error analysis of the proposed scheme is discussed and is shown $\varepsilon$-uniformly convergent. Numerical experiments for linear and nonlinear are performed to confirm the theoretical analysis.
Policy Instrument Supply and Demand: How the Renewable Electricity Auction Took over the World
Authors: Fitch-Roy Oscar W , Benson David , Woodman Bridget
Published: March 2019

The selection and design of renewable electricity support instruments is an important part of European Union (EU) energy policy and central to the governance of the Energy Union. In 2014, the European Commission published updated guidelines for state aid that effectively mandate the EU-wide implementation of auctions for allocating revenue support to commercial scale renewable electricity generation. This article argues that the RES auction’s rapid ascent towards dominance is explained by a coincidence of an activist interpretation of EU state aid law creating demand for knowledge about the instrument and the emergence of a ready source of supply from a burgeoning community of a RES auction specialists and experts. Knowledge gained through EU-wide implementation of auctions further adds to supply of auctions expertise among the community. The implications of positive feedback between instrument demand and the growing supply of knowledge about an instrument reinforces the importance of critical engagement between policymakers and policy experts.
The Effect of European Integration on Swiss Energy Policy and Governance
Authors: Van Baal Paul Adrianus , Finger Matthias
Published: March 2019

The unique “Swiss way” of association with the European Union (EU) has received increasing attention in light of recent events such as Brexit as it is based on sectoral agreements without an overarching institutional framework. As such, Europeanization of Swiss domestic policy does not follow a straightforward process. We examine the external governance processes that drive the Europeanization of Swiss energy policy. Switzerland and the EU are highly interdependent in energy due to Switzerland’s geographical position but there is a relatively low level of policy alignment, as there is no formal EU-Swiss energy agreement nor has Switzerland autonomously implemented legislation equivalent to the EU energy acquis. The EU has fully liberalized the energy market and is focusing on consumer empowerment and decarbonization through the Clean Energy Package, whereas the Swiss energy sector remains only partially liberalized. Through a series of expert interviews with key stakeholders, we reconstruct the historical developments in Swiss energy policy, focusing on the relationship with, and the influence of the EU. We observe elements of each of the three ideal modes of governance—markets, hierarchies, and networks. The relative importance of these modes of coordination in governing EU-Swiss energy relations has shifted considerably over time. Gradual harmonization of EU energy markets and certain key events have driven Swiss exclusion from EU network governance processes, leading to more hierarchy. We identify the strengths and weaknesses of each mode of governance for EU-Swiss energy relations in their historical setting and discuss the implications for energy policy in Switzerland in the context of the Clean Energy Package and EU external relations in general.
EU Agencies and the Energy Union: Providing Useful Information to the Commission?
Authors: Jevnaker Torbjørg , Saerbeck Barbara
Published: March 2019

The development of the energy policy of the European Union (EU) has been accompanied by organizational reforms of the EU’s energy bureaucracy. Much attention has been paid to Commission President Juncker’s reorganization of the European Commission, including how this has influenced the Energy Union initiative. The establishment of EU agencies has also expanded the EU administration and the capacity for developing new initiatives and coordinating implementation of EU legislation. However, recent research has not been sufficiently connected to policy studies on energy, climate and environment. This article analyses the extent to which two EU agencies—the Agency for the Cooperation of Energy Regulators, and the European Environmental Agency—augment the policymaking capacity of the Commission by providing information that aids its work. The article ends with a discussion of the potential implications of agencification.
Organised Interests in the Energy Sector: A Comparative Study of the Influence of Interest Groups in Czechia and Hungary
Authors: Horváthová Brigitte , Dobbins Michael
Published: March 2019

In this article, we explore civil society mobilisation and the impact of organised interests on the energy policies of two post-communist countries—Hungary and Czechia—and specifically nuclear energy. Drawing on numerous hypotheses from the literature on organised interests, we explore how open both political systems are for civil society input and what interest group-specific and socio-economic factors mediate the influence of organised interests. Based on the preference attainment method, our case studies focus on the extent to which organised interests have succeeded bringing nuclear energy legislation in line with their preferences. We find that while both democracies are open to civil society input, policy-making is generally conducted in state-industrial circles, whereby anti-nuclear and renewable energy advocates are at best able to make minor corrections to already pre-determined policies.
CALCULATION OF THE AMOUNT OF HEAVY METALS ENTERING TO THE NEAR-MOTORWAYS GEOSYSTEMS WITH VEHICLE EMISSIONS
Authors: Halahan O. , Korogoda N.
Published: March 2019

The article presents the method of obtaining data on the amount of heavy metals (HM), which enter to the near-motorways geosystems with vehicle emissions, with their refinement in accordance with the natural and anthropogenic features of the territory. Firstly, the model calculations take into account the intensity of the impact of the emission source, which depends on the parameters of the traffic flow. To clarify the amount of fuel consumed and, the emissions, as a result, were proposed: indicator Рf,, that defining part of cars, which used different types of fuel in a transport group. The need for this indicator is determined by the fact that different types of fuel have a varied spectrum of impurities in the exhaust gases, as a result of which they are sources of emission of various heavy metals. The next corrective indicator is Рf (age m), which determines the part of cars with different periods of use, because the amount of fuel used depends on it. The “refined” data thus obtained allows us to calculate the amount of heavy metals that “delivers” the traffic flow in a section of a highway during a certain period of time. Secondly, the methodology takes into account the natural conditions of the territory, which determine the spatial characteristics of the primary field of pollution. Because the natural features of the territory also affect changes in fuel consumption. In accordance with this, a number of coefficients are introduced in the calculation methods. Orographic coefficients allow taking into account the differences in fuel consumption by the traffic flow on the road sections with different absolute heights (Кa.h.) and the slope of the roadway (Кsl). Climatic “corrective” coefficients make it possible to clarify the additional fuel consumption arising from the operation of a vehicle on days with low temperatures (coefficient Кt) and days with adverse weather conditions (coefficient Кex). It will be possible to talk about the estimated amount of fuel consumed and, as a consequence, the emissions of heavy metals that form the primary field of contamination.
The proposed approach allows determining the degree of influence of motor transport to the near-motorways geosystems and is part of a general algorithm that describes the formation of actual level of contamination in the soil of near-motorways geosystems by heavy metal compounds.
The actual level of contamination, in the proposed algorithm, is proposed to be defined as the difference between the volumes of HM, which were introduced into the soil of geosystems for a certain period of time and taken out of its limits and / or excluded from migration flows during the same time interval.
Turning Points in Horse Breeding in the Eurasian Steppes and the Near East
Authors: Kovalevskaya V. B.
Published: March 2019

This article discusses the pivotal points in horse domestication on the Eurasian steppes and the Near East in the 5th to 2nd millennia BC, from the initial time and place of the domestication of horses to the emergence of various types of horse harnesses. On the basis of 5th and 4th millennia BC Eurasian horse-headed scepters, the means for handling horses are reconstructed. Six types of head harnesses are described, and their evolution is traced from simple muzzles (type 1) and more complex ones (types 2 and 3) to those supplemented with drop nosebands (type 4) and snaffl e (type 5) and non-snaffl e bridles (type 6). A unique 3rd millennium BC document—an Elamite clay tablet from Susa, listing horse farms, has made it possible to assess the structure of each farm, and evaluate the size of the domestic horse population in Elam. Training techniques of chariot horses were described by the “master horse trainer Kikkuli of Mitanni”. These techniques were further developed by the proto-Indo-Aryans on the Eurasian steppes in the early 2nd millennium BC, and became known to the Hittites and Assyrians via the Mitanni horse breeders. On the basis of the Rigveda, the type and exterior of those swift horses with which the Indo-Aryans spread over Asia are characterized.
Early Iron Age Pyramidal Kurgans in Western Siberia
Authors: Matveeva N. P.
Published: March 2019

Ditches encircling the Early Iron Age Sargatka kurgans in the Western Siberian forest-steppe are described. Most of them are nonagonal, decagonal, and dodecagonal, but hexagonal, heptagonal, octogonal and those with 14 angles occur as well. Kurgan shape does not correlate with size, platform diameter, or number of burials. The analysis of data regarding the micro-relief of the kurgan surface and of sources relevant to early nomadic religion enables us to interpret various types of ditches. Those of the hexaand heptagonal type encircled a wooden and earthen pyramid, presumably symbolizing the World Mountain. Those with 9, 12, and 14 angles result from a proportionally larger size of elite kurgans. Indeed, inside such kurgans, hexa- and heptagonal wooden platforms are found. Unclosed ditches likely indicate unfi nished kurgans, and those with 11 and 13 angles result from a distortion of the initial layout by secondary burials. Ditches are associated only with male burials and were apparently meant to protect the dead against evil forces and against the possible intrusion of potentially hostile ancestors, whose cult was reconstructed on the basis of offerings in elite burials. The architecture of the Sargatka kurgans evidences remnants of Indo-European myths transformed by inter-ethnic contacts and cultural innovations on the periphery of the Scytho-Siberian world.
A Central Asian Helmet from the Northern Kazakhstan Regional Museum
Authors: Bobrov L. A. , Ismailov D. M.
Published: March 2019

We describe a richly decorated iron helmet owned by the Northern Kazakhstan Regional Museum in Petropavlovsk. It consists of a low solid hemispherical crown, a slightly convex plate, made of copper alloy, with an opening for a (missing) tube in which the plume was inserted, a wide iron hoop, and a bipartite visor of the box type. The two last-named elements are covered with Arabic inscriptions inlaid in gold. Those on the hoop are verses from the Quran 2, 255–257, Al-Baqarah — The Cow. That on the “shield” of the visor is a prayer for protection, known as the “message of peace” read before a long journey or a diffi cult and dangerous enterprise, such as a battle. Such helmets were common in Central Asia between the late 16th and the mid-18th centuries. This specimen was likely manufactured in Mawarannahr, Xinjiang, or some town on the Syr Darya, for a high-ranking Uzbek, Uyghur, or Kazakh warrior. This accounts for the combination of a solid crown and a hoop with Arabic inscriptions with a box-type visor typical of helmets worn by Mongolian and Turkic nomads during the Late Middle Ages and the Early Modern Age. The closest parallels are found in the museums of Kazakhstan. Judging by the traces of repair and reconstruction, this helmet was used for a long time.
Wearing Folk Costumes as a Mimetic Practice in Russian Ethnographic Field Studies
Authors: Kucherskaya M. A.
Published: March 2019

Wearing folk costumes was a mimicry practiced by certain mid-19th-century Russian ethnographers and folklorists. The most consistent of these was Pavel Yakushkin, who posed as a peddler when doing fi eld work in villages. In this he followed the instructions written by the famous writer, historian, and antiquary Mikhail Pogodin. The sources of Pogodin’s ideas on how a folklorist and ethnographer should look were the Slavophiles’ perception of the Russian costume, Alexander Pushkin’s habit of wearing a red shirt, as well as court jokes and folk legends about top-ranking persons wearing folk costumes. While the changing of clothes fi rst used by Yakushkin was later adopted by other ethnographers, such as Sergey Maksimov and Pavel Rybnikov, political reasons prevented it from spreading. Nevertheless, in the 1870s, at the peak of the movement of the Narodniki (Populists), using folk costumes re-emerged as a way of bringing the intelligentsia closer to the peasants and workers. The erosion and eventual disappearance of class boundaries in Soviet Russia made such ways of winning confi dence pragmatically irrelevant; however, wearing traditional folk costumes as a political gesture is meaningful even today.
Types of Winter Clothing Worn by Descendants of the Russian Pioneers in Siberia (Late 19th to Early 20th Centuries)
Authors: Fursova E. F.
Published: March 2019

Warm clothing was an important cultural adaptation, enabling the Russian pioneers to survive in the harsh climate of Siberia. The sources for the study are archival documents, including V.K. Multinov’s manuscript “Clothing of the Angara People” (1926), results of fi eld studies in the 1970s and 1980s by the present author, museum artifacts, and collection inventories compiled by A.N. Beloslyudov, S.P. Shvetsov, I.I. Baranova, and I.I. Shangina, as well as data collected by climatologists, technologists, and designers. Types of winter clothing, including outfi ts for hunting and fi shing, worn by the Russians living on the Angara, in the Altai, and Trans-Baikal, are described. These include cloth-covered and non-covered fur coats, short fur coats, those with the fur on the inside, robes, as well as warm pants, fur hats, boots, and mittens. Protection from the cold was ensured by the use of high-volume insulating materials, several layers, and by habits such as tucking one piece of clothing into another (the so-called “Siberian one-piece garment”). Specific features in Siberia are observed, including the use in winter hunting outfi ts of certain elements of native Siberian clothing (specifi cally that of the Tungus clothing on the Angara), and the women’s habit of wearing men’s garments with belts.
MORPHOLOGICAL AND FUNCTIONAL SYSTEM OF GRAFT-ARTERY JUNCTIONS
Authors: Frolov A. V.
Published: March 2019

The review describes current state of myocardial revascularization using both venous and arterial grafts in terms of their morphology and function. A new framework of the graft-artery junction as a separate morphological and functional system has been proposed. Taking into account numerous data and separate evidences, this system may be separated into a single unit characterized by mutual relations. On the one hand, the graft produces favorable effects on the coronary artery protecting from atherosclerosis, on the other, the coronary artery itself may provoke specific changes in the graft. The proposed graft-artery junction provides new insight into the decision-making process for the graft selection in coronary artery bypass grafting.
HOSPITAL OUTCOMES IN PATIENTS WITH NON-ST-SEGMENT ELEVATION ACUTE CORONARY SYNDROME ACCORDING TO CLINICAL PRACTICE
Authors: Sinkov M. A. , Kochergin N. A. , Ganyukov V. I.
Published: March 2019

Background. Non-ST elevation acute coronary syndrome (NSTE-ACS) is a common cause of hospital admissions of coronary artery disease patients.

Aim. To assess clinical and epidemiological patterns and hospital outcomes of treatment of NSTE-ACS in Kemerovo in period from 2015 to 2017.

Methods. 4884 patients with NSTE-ACS admitted to the Kemerovo healthcare facilities in the period from 2015 to 2017 were included in a retrospective observational study. In-hospital period was subjected to the analysis.

Results. The morbidity of NSTE-ACS increased by 16.92% (from 267.78 cases in 2015 to 302.13 cases per 100 thousand population in 2017). The rate of invasive treatment strategies in patients with NSTE-ACS did not change significantly within the study period (about 33%). In-hospital mortality from NSTE-ACS slightly decreased (from 3.74% in 2015 to 3.21% in 2017, p = 0.681).

Conclusion. The observational study reported a tendency towards increasing prevalence of NSTE-ACS in a large industrial center within the 3-year period by 16.92%. Nevertheless, the availability of invasive treatment in Kemerovo within the study period remained high (33%). However, relatively high in-hospital mortality rate (3.36%) in NSTEMI has been determined and requires additional studies.

Aim. To study the relationship of the perception of illness and coping strategies in patients with ischemic heart disease before coronary artery bypass grafting with purpose in life orientation. Methods. The study included 108 males aged 45 to 73 years with a diagnosis of ischemic heart disease. Clinical and psychological diagnostics included the study of the patient's perception of illness using the Personal Questionnaire of the Bekhterev Institute, the coping strategies were assessed with the Ways of Coping scale developed by Lazarus and Folkman. To study the purpose in life orientation (formation of goals in life, the level of self-realization of a person, meaningfulness and saturation of life in the past and present, plans for the future), the «Purpose-in-Life Test» by D.A. Leont'ev was used. Results. The study showed the predominance of adaptive variants of the perception of illness and moderate use of both productive and unproductive coping strategies in the studied group, as well as the preservation of aims and guidelines for the future in the situation of preparing for coronary bypass surgery. A positive relationship was found between the indicators of general meaningfulness of life, dedication, satisfaction with the process of activity and achievement of results with the indicators of adaptive variants of the perception of illness and productive coping behavior. Low levels of overall meaningfulness of life, inability to set goals and achieve them, as well as lack of satisfaction from past events, are associated with high rates of maladaptive variants of the perception of illness and the choice of unproductive coping strategies. Conclusion. A high level of purpose in life orientation in patients with ischemic heart disease can lead to the formation of adaptive variants of the perception of illness variants and productive coping strategies, whereas a low level of purpose in life orientation probably leads to the risks of the formation of maladaptive perception of illness variants and coping strategies.

Published: March 2019

Aim. To study the role of oxidative protein modification of bone tissue proteins in the formation of destruction of temporal bone structures in chronic otitis media. Methods. The study included 139 patients aged 16-75 years with a verified diagnosis of chronic otitis media, who are candidates for surgical treatment. Depending on the method of surgical treatment, patients are divided into four groups (by nosology and complications and reoperations): patients with tubotympanic otitis media and epitympanic antral otitis, without complications and with local or intracranial complications, after reconstructive sanitizing ear surgery. The state of the processes of oxidative modification of proteins was evaluated in the bone tissue of the middle ear cavities, obtained intraoperatively, by the content of carbonyl products with the use of spectrophotometry. The data were processed by descriptive statistics and were presented in the form of a median and a range between quartiles with an estimate of the reliability of the intergroup differences by the Mann-Whitney U-criterion. Results. A comparison of the indicators characterizing the oxidative modification of bone tissue proteins of the temporal bone in patients with complicated and recurrent forms of chronic otitis media demonstrates a greater degree of free radical destruction of proteins, primarily markers of early stages of protein damage and an increase of aldehyde products, both at the basal level and in response to induction in a complicated course of the disease. Conclusion. The obtained data allow drawing a conclusion about a high level of oxidative stress in bone tissue in destructive forms of chronic otitis media accompanied by relapses and complications, and about the perspectives of antioxidant pre-operative use taking into account the features of oxidative stress in bone tissue in patients with chronic otitis media.

Published: March 2019

Aim. To study the dynamics of indicators of microcirculation during a single episode of hypothermia of moderate degree in rats, both immediately after cessation of cooling, and in different periods of posthypothermia. Methods. The study was performed on 25 Wistar rats. The animals were subjected to a single immersion cooling in water at a temperature of 5 °C until reaching a rectal temperature of 27-30 °C. Analysis of the microvasculature was carried out immediately upon reaching a moderate degree of hypothermia, 2, 5, 10 and 14 days after the cooling. The microcirculation parameters were estimated using a laser analyzer of capillary circulation LAKK-02 (SMO «Lazma», Russia) at a wavelength of 0.63 μm. The main parameters of microcirculation were recorded, and the amplitude-frequency spectrum of blood flow oscillations was analyzed. Results. Immediately after reaching a moderate degree of hypothermia, vasospasm was recorded, which was confirmed by a decrease in the rate of perfusion and wave amplitudes of all frequency ranges. 2 days after stopping the cooling perfusion index returned to baseline, a decrease in amplitude of endothelial, vasomotor and respiratory waves was observed with an increase in pulse waves. On day 5, perfusion increased by 5 times was observed along with decreased amplitudes of the waves of all ranges. By day 10, the level of blood flow returned to its original values, and the wave amplitudes of all frequency ranges remained at the same low level. By day 14, a progressive decrease of the factors of bloodflow modulation was associated by the decrease of perfusion. Conclusion. Single cooling to a moderate degree of hypothermia leads to a progressive decrease of tissue perfusion and deep inhibition of active and passive factors of bloodflow modulation.
Current views on the possibility of cervical insufficiency correction
Authors: Yakovleva O V , Glukhova T N , Rogozhina I E
Published: March 2019

The main role in spontaneous abortion in 2nd and 3d trimesters is assigned to cervical insufficiency. According to a number of researchers, bed rest, elevated lower limbs, restriction of physical activity, tocolysis, antibacterial therapy do not affect the prolongation of pregnancy and are ineffective for preventing premature spontaneous labor. Correction of cervical insufficiency can be carried out by a vaginal form of progesterone, cerclage, pessary. The use of vaginal progesterone is justified in women with recurrent miscarriage, a history of premature birth, and shortening of the cervix to less than 25 mm. Indications for surgical correction are limited to patients with habitual loss of pregnancy due to cervical weakness or a history of premature birth. In the absence of significant obstetric history, cerclage has no advantages over the use of progesterone. The optimal time for cerclage is up to 20 weeks of pregnancy. Unlike progesterone cerclage has complications, the frequency and severity of which are attributable to the timing and indications for correction. Transabdominal cerclage is performed only when there is a technical impossibility of vaginal access due to the absence of a vaginal part of the cervix or after unsuccessful attempts of vaginal cerclages. Most often, the use of a pessary is associated with the diagnosis of a short cervix in terms of more than 24 weeks of gestation in the absence of an aggravated history. The combined use of gestagens, pessary and cerclage does not increase the efficiency of carrying a singleton pregnancy. Methods for the prevention of preterm delivery in multiple pregnancy, such as the introduction of a specialized outpatient service, bed rest, antibacterial therapy, progesterone, preventive cerclage or the insertion of a pessary do not change the incidence and mortality of newborns.
The problem of routing of patients using psychoactive substances
Authors: Pichugin A N
Published: March 2019

Alcoholism and drug addiction are concomitant or indirect causes of death in almost all subclasses of diseases, as well as frequent causes of violent death. In the field of detection, treatment, prevention and support of the studied group of patients, there is a huge number of problems, such as anosognosia, possible limitation of patients' rights, socially restrictive nature of addiction care, etc. As a result, patients taking psychoactive substances, have significantly reduced motivation to appeal to narcologists. There are many systemic organizational problems in the work of the addiction service, which significantly hamper the routing of patients, which differs from the routing of patients of somatic profile. In relation to this, scientific research aimed at optimizing drug addiction service is of particular relevance. In addition, each subject of the Russian Federation has a number of features (territorial, economic, i.e.), and this indicates the need to study certain types of specialized assistance, taking into account the characteristics of each specific region. There are several levels of patient routing, each of which includes certain tasks, components, and indicates the expected result. The routing of addictive patients has its own peculiarities, related both to temporary isolation of patients and to further long-term rehabilitation. As a result, the model of highly specialized care for patients using psychoactive substances does not allow involving the greatest possible number of people in need in each stage of therapy and does not contribute to solving the main public health problems. Despite the obvious availability of this type of assistance, for most potential customers it remains unattractive.
Entre o teatro e a História: a peça Secretário d’El Rei de Oliveira Lima
Authors: Carvalho Ricardo Souza de
Published: March 2019

O artigo discute as relações entre teatro e História a partir do estudo da peça Secretário d’El Rei (1904) de Oliveira Lima. Embora seja a única produção do autor no gênero e jamais tenha sido encenada, a peça mostra-se como um caso relevante sob esse aspecto, ao se articular tanto com a experiência de Oliveira Lima com o teatro português do final do século XIX, quanto com o seu trabalho de historiador. Além disso, buscando aliar vivacidade à fidelidade com o espírito de uma época, Oliveira Lima concentrou-se na exploração dos caracteres históricos, ao dramatizar a relação entre Alexandre de Gusmão e D. João V, motivada por uma situação ficcional.
“criticismo de gêneros” na poética de Guimarães Rosa

Published: March 2019

Resumo: Autor de contos, novelas e do romance Grande sertão: veredas, Guimarães Rosa é reconhecido pela engenhosidade de suas narrativas e por um estilo que seria expressão de uma personalidade artística ímpar na literatura brasileira. O poder que suas narrativas têm de surpreender os leitores em suas expectativas convencionais se manifesta de modo singular no último livro do escritor. Neste artigo, pretendemos apresentar e analisar o modo como Tutaméia: terceiras estórias está sistematicamente voltado a desautomatizar o leitor das convenções na apreensão da verossimilhança e como suas estórias e prefácios encenam aquilo que, segundo Bakhtin, seria a característica do romanesco enquanto gênero: o “criticismo”.Palavras-chave: Guimarães Rosa; Tutaméia; Bakhtin; romanesco; teoria dos gêneros.Abstract: Author of a range of literary genres, such as short stories, novels and the well-known novel Grande Sertão: Veredas, Guimarães Rosa is recognized for the ingenuity of his narratives. Moreover, the author is acknowledged for a style which is the expression of a unique artistic personality in Brazilian literature. The power of his narratives to astonish readers’ conventional expectations is manifested in his last book, Tutameia: Terceiras Estórias, in quite a singular way. In this article we intend to present and analyze the way in which Tutameia: Terceiras Estórias is systematically aimed at de-automating the readers’ conventions regarding their apprehension of verisimilitude. In addition, it is intended to show how Guimarães Rosa stories and forewords stage what Bakhtin would define as the characteristic of the Romanesque as a genre: the “criticism”.Keywords: Guimarães Rosa; Tutameia; Bakhtin; romanesque; genre theory.

Ideas of inheritance, incompleteness, and reinvention contribute to a thought on the creations that move among prose, verse and song, overcoming specific thresholds of artistic-literary genres.Keywords: Guimarães Rosa; Celso Adolfo; Sagarana; literature; music.
“A Rosa da palavra”
Authors: Marchioro Camila
Published: March 2019

Resumo: O estudo que se segue é uma tentativa de analisar Primeiras estórias (1962) a partir da hipótese de que existe, na escrita de Guimarães Rosa, uma provocação meditativa que se dá por meio da presença de um elemento causador de estranhamento, ostraniênie. Para auxiliar a investigação, foram usados como base os estudos de Viktor Shklovsky (1976) e Carlo Guinzburg (2001) sobre o estranhamento em cotejo com algumas noções manifestas em cartas e entrevistas de Guimarães Rosa em que o escritor fala sobre seu processo de criação. Utilizam-se ainda, a fim de aprofundar a questão da meditação e do autoconhecimento nas Primeiras estórias, algumas referências vindas do cânone budista, uma vez que os sutras e koans são exemplos antigos do uso de estranhamento com o objetivo de prender a atenção do ouvinte ou leitor e de fazê-lo meditar sobre um tema. Os resultados mostram que uso do estranhamento é eficaz como modo de provocação meditativa e que a meditação é de fato algo relevante para o processo de composição e recepção da obra de Guimarães Rosa.Palavras-chave: meditação; estranhamento; Primeiras estórias.Abstract: The following study attempts to analyze the book Primeiras Estórias (1962) from the hypothesis that in the writing of Guimarães Rosa exists a meditative provocation which occurs through the presence of an estrangement element, ostraniênie. To help the investigation, Viktor Shklovsky’s (1976) and Carlo Guinzburg’s (2001) studies are used in comparison with some letters and interviews by Guimarães Rosa in which he talks about his creative process. In order to deepen the question of meditation and self-knowledge in Primeiras Estórias, some references from the Buddhist canon are used, since sutras and koans are ancient examples of the use of estrangement in order to hold the listener’s/reader’s attention and to make one meditates on a subject. The results show that the use of ostraniênie is a mode of meditative provocation and meditation is indeed something relevant to the process of composition and reception of the work of Guimarães Rosa.Keywords: meditation; estrangement; Primeiras Estórias.
Connections from trivializations
Authors: Kurek Jan , Mikulski Włodzimierz
Published: March 2019

Let P be a principal fiber bundle with the basis M and with the structural group G. A trivialization of P is a section of P. It is proved that there exists only one gauge natural operator transforming trivializations of P into principal connections in P. All gauge natural operators transforming trivializations of P and torsion free classical linear connections on M into classical linear connections on P are completely described.

Authors: Cavalheiro Albo Carlos
Published: March 2019

In this work we are interested in the existence and uniqueness of solutions for the Navier problem associated to the degenerate nonlinear elliptic equations \begin{align} {\Delta}(v(x)\, {\vert{\Delta}u\vert}^{p-2}{\Delta}u) &-\sum_{j=1}^n D_j{\bigl[}{\omega}_1(x) \mathcal{A}_j(x, u, {\nabla}u){\bigr]}+ b(x,u,{\nabla}u)\, {\omega}_2(x)\\ & = f_0(x) - \sum_{j=1}^nD_jf_j(x), \ \ {\rm in } \ \ {\Omega} \end{align} in the setting of the weighted Sobolev spaces.

Authors: Bielak Halina , Broniszewska Katarzyna
Published: March 2019

In this paper we show some properties of the eccentric distance sum index which is defined as follows \(\xi^{d}(G)=\sum_{v \in V(G)}D(v) \varepsilon(v)\). This index is widely used by chemists and biologists in their researches. We present a lower bound of this index for a new class of graphs.

Authors: Bohner Martin , Geetha Srinivasan , Selvarangam Srinivasan , Thandapani Ethiraju
Published: March 2019

The aim of this paper is to investigate the oscillatory and asymptotic behavior of solutions of a third-order delay difference equation. By using comparison theorems, we deduce oscillation of the difference equation from its relation to certain associated first-order delay difference equations or inequalities. Examples are given to illustrate the main results.

Antydyskryminacyjna rola geografii w kształtowaniu postaw tolerancji wobec mniejszości narodowych i etnicznych
Authors: Zatorski Michał Jan
Published: March 2019

W trakcie podstawowej szkolnej edukacji geograficznej uczniowie nie mają świadomości, że nabyte wiadomości i umiejętności są tymi niezbędnymi do właściwej percepcji i obserwacji zjawisk społecznych i przyrodniczych. Wdrażając elementy edukacji antydyskryminacyjnej do realizowanych treści geograficznych, pozwoli na wzmocnienie praktycznej i wychowawczej roli geografii. To uczyniłoby z geografii naukę pojednania pomiędzy narodami, w myśl słów prof. Stanisława Pawłowskiego „Jedna jest Ziemia i jeden człowiek na niej". Dodatkowo korelacja z treściami historycznymi byłaby odpowiedzią  na systemowe rozwiązanie braku edukacji antydyskryminacyjnej w polskich szkołach.
Funkcjonowanie ekomuzeów w Bieszczadach i Beskidzie Niskim w świetle badań ankietowych
Authors: Buczek-Kowalik Małgorzata , Mitura Teresa
Published: March 2019

W artykule przedstawiono teoretyczne zasady funkcjonowania ekomuzeów w przestrzeni geograficznej wybranych regionów europejskich. Zaprezentowano rozwój ekomuzeów w Polsce, a w szczególności w Bieszczadach i Beskidzie Niskim. Do analizy i oceny funkcjonowania  wybrano następujące  ekomuzea – Trzy Kultury, Hołe (Bieszczady) oraz Beskidzkie Wędrowanie (Beskid Niski). W badaniach zastosowano metodę MACDAB, na podstawie której zidentyfikowano problemy związane z ich działalnością, a także wskazano na elementy, które poprawiłyby jakość ekomuzeów jako jednego, spójnego produktu turystycznego.

 Otrzymane wyniki wskazują, że najwyższą liczbę punktów otrzymało Ekomuzeum Trzy Kultury, zaś najniższą – Ekomuzeum Hołe. Według przyjętych kryteriów wszystkie z analizowanych ekomuzeów, znalazły się drugiej grupie tzn. wykazują trudności w przyjmowaniu zasad „wzorcowego ekomuzeum”.
W celu poprawy działalności ekomuzea powinny w szerszym zakresie współpracować ze sobą i innymi podobnymi ośrodkami w kraju i za granicą.  Poza tym należałoby  uskutecznić działalność promocyjno – marketingową poprzez m.in. wspólną stronę internetową, wydawanie wspólnych materiałów promocyjno – reklamowych oraz współpracę ze szkołami czy podmiotami zajmującymi się  organizacją imprez turystycznych
Uwarunkowania klimatyczne turystyki w Wietnamie
Authors: Matuszko Dorota , Kopaczka Diana , Celiński-Mysław Daniel
Published: March 2019

Wietnam jest krajem coraz chętniej odwiedzanym przez turystów z całego świata. Warunki klimatyczne tego kraju mogą być pewnym ograniczeniem dla osób przybywających z innej strefy klimatycznej z powodu wysokiej temperatury i dużej wilgotności powietrza oraz częstych opadów. Jednak duża rozciągłość południkowa Wietnamu i urozmaicona rzeźba terenu pozwalają znaleźć okres najbardziej korzystny do zwiedzania lub wypoczynku. Celem opracowania jest charakterystyka wybranych elementów klimatu Wietnamu, które sprzyjają lub utrudniają turystykę w tym kraju oraz wpływają na postrzeganie jego walorów turystycznych.

W pracy wykorzystano dane meteorologiczne z 28 stacji, rozmieszczonych równomiernie na terenie Wietnamu z lat 2001 do 2015. Przedstawiono i dokonano analizy przebiegu rocznego sum opadów, liczby dni z opadem,  temperatury maksymalnej oraz wilgotności względnej na wybranych stacjach.

W Wietnamie północnym najbardziej dogodnym sezonem do uprawiania turystyki pod względem warunków pogodowych jest okres od listopada do marca. W tym czasie panuje sytuacja antycyklonalna, temperatura maksymalna waha się średnio od 20.0oC do 30.0oC, wilgotność względna jest najmniejsza, a częstość dni z opadem jak i same sumy opadów są stosunkowo niskie. Najmniej korzystnym sezonem dla turystyki są miesiące od maja do sierpniu z powodu wysokiej temperatury, przekraczającej 30.0oC, dużej wilgotności (powyżej 80%) oraz obfitych i częstych opadów.

W Wietnamie środkowym najwyższe temperatury panują od kwietnia do maja, a maksimum opadów przypada na miesiące od sierpnia do listopada.

Na południu Wietnamu klimat jest bardziej stabilny, wilgotność i temperatura powietrza wysoka (powyżej 30.0oC) ale prawie wyrównana w ciągu roku. Na okres od maja do października przypada pora deszczowa. Charakteryzuje się ona prawie codziennymi ulewami, bardzo silnymi ale krótkotrwałymi, zazwyczaj wieczorem. Jednak przy bardzo dużej wilgotności w ciągu dnia taki opad może przynosić ulgę i poprawę samopoczucia. Z tego względu w Wietnamie południowym trudno wyróżnić miesiące szczególnie korzystne dla turystyki. W zasadzie region ten można zwiedzać cały rok, ale należy być przygotowanym na dużą wilgotność i wysoką temperaturę powietrza. Na wybrzeżu, szczególnie w rejonie delty Mekongu w porze deszczowej występują tajfuny. Są one najbardziej niebezpieczne w sierpniu i we wrześniu.

 
Line × tester analysis in rapeseed: Identification of superior parents and combinations for seed yield and its components
Authors: Rameeh Valiollah
Published: March 2019

This research was carried out to investigate the genetic structure of the 20 F1s rapeseed hybrids established from five female moderate maturity lines and four early maturity male testers, to determine parents showing general combining ability (GCA) and detect crosses showing specific combining ability (SCA). Significant variance of parents and crosses for all the traits indicated the existence of significant genetic variation among the parents and their F1 cross combinations. Significant variance of parents vs. crosses revealed significant average heterosis for all the traits except first pod height and seeds per pod. High narrow-sense heritability estimates for number of branches and pods length, indicate the importance of additive genetic effects for these traits. Hybrid performance was generally better than parental performance for all the traits except number of branches and also the genetic variation of lines × testers for all the traits were more than lines and testers. Most of the crosses with high mean value of pods per plant were yielded from the parental lines with high mean value of this trait. The crosses including L41×Foma2, Zafar×R42 and L22B×R38 with significant positive SCA effects of seed yield had also high mean values (3400, 3311.3 and 2904.2 kg ha-1 , respectively) of this trait.
Water parameters and species composition of macrophytes in reclamation lakes in the area of a former sulphur borehole mine (SE Poland)
Authors: Krawczyk Rafał , Lis Łukasz , Urbaniak Jacek
Published: March 2019

Macrophytes and selected physical-chemical water properties were studied in 17 post-mining lakes of Jeziórko Sulphur Mine – one of the largest borehole sulphur mines in the world. Artificial lakes were constructed in subsidence depressions during the reclamation process of mining fields. They were characterized by high mineralization – conductivity ranged from 723 to 2295 μS/cm. The reaction was near neutral, or more frequently, slightly alkaline. Concentrations of phosphorus and organic matter were low. In the group of hydrophytes, Ceratophyllum demersum, Myriophyllum spicatum, Najas marina, Utricularia vulgaris, Eleocharis acicularis, Potamogeton pectinatus, Potamogeton natans and Potamogeton pusillus were frequently dominant. In several lakes, large macroscopic algae dominated – charophytes forming large, dense Chara meadows. In marsh communities, Phragmites australis was the most expansive. Reclamation process had a positive effect on diversity, some of the species found in the study area are regionally rare, including one species which is threatened in Poland (Najas minor). No alien species were recorded.
