Abstract. 451 lethal outcomes of 5581 casualties with gunshot wounds occurring at the medical treatment facilities have been analyzed. Total lethality rate was 8,1%. Lethal outcome time varied from 1 to 19 days (10,61,9). 50,3% of casualties died during the advanced trauma management (Role 2), 17,3% at the Role 3 hospitals, 32,4% at the Role 4 hospitals. The predominant injury localization causing death was abdominal wounds 34,8%, and head injuries 23,1%. The main cause of death of wounds casualties arriving at the medical treatment facilities was life-threatening injury consequences (34,8%) and developing complications (45,5%). Fatal injuries to the major organs and permanent blood loss were considered to be the cause of death in 19,7% of casualties. 37% of the total number of lethal outcomes died because of acute blood loss, in 77,2% of cases it was internal hemorrhage, in 22,8% external hemorrhage. In 1% of cases early death was caused by acute respiratory failure. In general, the development of more than one third of lethal outcomes could be prevented. Special medical products and equipment were developed by the Department of War Surgery Kirov Military Medical Academy, RF Ministry of Defense in cooperation with the leading research and educational establishments and production enterprises. They are: equipment for the prehospital hemorrhage control, asphyxia management, open and tension pneumothorax management, traumatic shock treatment and complication prevention, as well as activities for creating devices controlling internal hemorrhage. All these form the basis for elimination of life-threatening consequences of injuries at the prehospital stage. This allows us to discuss the development of the idea of a traumatic disease, being put forward by professor Ilia Deriabin, in terms of the concept of the early-stage pathogenetic treatment of the severe injuries and traumas.

Abstract. The effectiveness of the influence of autologous mesenchymal stem cells on the function of liver tissue in liver cirrhosis of alimentary etiology is considered, as well as the possibility of visualization of the introduced cell structures with subsequent cytological confirmation. To be able to track autologous mesenchymal stem cells introduced in the patients body, they were labeled with iron oxide nanoparticles. Visualization of the introduced cell structures was performed using magnetic resonance imaging and ultrasound examination of the liver. 6 months after the cell therapy, clinical and biochemical blood tests, lidocaine test results, elastography indicators were evaluated, and the dynamics of hepatic encephalopathy was evaluated. The effectiveness of using autologous mesenchymal stem cells was evidenced by the improvement of the above indicators. Also, 6 months after treatment, a liver tissue biopsy was performed from the sites of fixation of previously introduced cell structures. Histological examination revealed the largest number of labeled cells in the liver micro-nodes, as well as at the borders of micro-nodes and fibrous septa. The use of cell therapy in a patient suffering from liver cirrhosis of alimentary etiology helped to improve the indicators of laboratory and instrumental research methods. No complications were detected during the procedure.

Abstract. This piece of work has evaluated the quality of medical care provided in 2015 to 1,158 patients with acute gastrointestinal bleeding in 11 medical institutions of Saint Petersburg that are licensed to provide in-patient examination and treatment for people with acute surgical diseases abdominal organs. The data on the possible correlative relationship of negative consequences for the implementation of the medical treatment and diagnostic process in cases of insufficient activity in terms of conducting clinical expert work on the profile of emergency abdominal surgery have been analysed in particular. It has been shown that providing medical care to patients with gastrointestinal bleeding is associated with defects in the medical diagnostic process in almost every second case. In the structure of inaccuracies, there prevailed cases of improper examination and treatment of patients (48 and 36%, respectively). Defects in making diagnosis and providing continuity comprise 13 and 3% respectively. The most significant drawback in providing medical care to patients with gastrointestinal bleeding was the use of low-effective anti-ulcer drug therapy schemes (16% of observation cases) and attempts to perform hemostasis by using outdated technologies of intraluminal endoscopy (16% of cases). It is noted that in cases of providing medical care to patients with acute gastrointestinal bleeding, a differentiated principle should be observed. It is proved that the proper quality of medical care for patients with acute gastrointestinal bleeding can be achieved by consistent, programmed provision of it with coordinated activities not only of surgeons directly involved in the treatment and diagnostic process, but also with their purposeful interaction with specialists of other medical fields.

Аbstract. The current regulatory framework of the Ministry of Health and the Ministry of Defense of the Russian Federation on the regulation of the provision of medical assistance to military personnel affected by the infection caused by the SARS-CoV-2 coronavirus is considered. The state of the problem of information support for the provision of medical care to military personnel of this category is assessed. The developed methodology and the draft regulatory document for organizing the collection of medical information in the register of military personnel affected by the infection caused by the SARS-CoV-2 coronavirus are presented, and a regulation on this register is developed. The content, scope and algorithm of creating an information-analytical system for registering this pathology among military personnel, as well as the need to introduce new medical document management technologies into the medical service of the Armed Forces of Russia based on personified records of military personnel and the medical and psychological assistance provided to them, are substantiated. It is shown that for the smooth functioning of the register within the framework of a justified list of tasks, the presence of high-speed secure communication channels between the participating military units, institutions and medical service management bodies will be required. Consequently, the improvement of the information support system for managing the medical support of troops in peacetime and wartime is an important component of increasing the effectiveness of managing medical support for military.

Abstract. In 1940, having baggage of three fatal two-stage pancreatoduodenal resections, during the demonstration surgery, the famous American surgeon Allen Whipple performs the first successful one-stage pancreatoduodenal resection for pancreatic head cancer. It is immeasurable surprise and respect that such a volume of intervention was not planned, since the patient was diagnosed with a tumor of the antral part of the stomach before the operation. The complexity of the situation didn`t stop Allen Whipples plans, and the subsequent success, which gave not only 9 years of life of the operated patient, but also to the whole world the original method of operation, became the starting point of a new era of pancreatic surgery Whipples contribution to surgery is not limited to performing one-stage pancreatoduodenal resection. He pioneered the reform of postgraduate medical education in the United States of America, founded the worlds first plastic surgery training program, developed new methods of intra- and perioperative management of patients with colon cancer, criteria for diagnosing insulinoma, which are today called the Whipples triad. The study of the structure of the spleen, as well as its role in the spread of tumor cells, made it possible to determine the indications and contraindications for splenectomy. He also developed and applied porto-caval and splenorenal shunting operations, which reduce pressure in the portal vein system in patients with liver cirrhosis.

A comparative analysis of clinical and epidemiological data and results of treatment of 7 patients suffering from myocardial infarction without obstructive coronary artery disease (main group) and 54 patients with their lesions (control group) aged 45,69,3 and 62,714,2 years, respectively. Both groups were dominated by men (85,7% and 72,2%, respectively). In the main group, dyslipidemia and hypertension were less common (14,3 and 28,6%, respectively) than in the control group (61,1 and 72,2%, respectively). At the same time, the former had a more burdened history of early cardiovascular events in close relatives in 28,6% of cases, and the latter-only in 5,6% of cases. Surgical tactics and features of double antiplatelet therapy in myocardial infarction without obstructive coronary artery disease did not differ from the standard approach. In both groups, active surgical tactics prevailed, consisting in performing percutaneous coronary intervention and installing a coronary stent in the infarct-related artery (85,7 and 83,3%, respectively). The choice of dual antiplatelet therapy in the main group did not differ from the control group and was characterized by a significantly higher frequency of clopidogrel administration (71,4 and 72,2%, respectively). When comparing the left ventricular ejection fraction before and after percutaneous coronary intervention, it turned out that in patients of the main group, in contrast to the control group, the value of the left ventricular ejection fraction did not change significantly (52,56,4 and 51,39,5, respectively). The etiology and pathogenesis of myocardial damage in patients suffering from myocardial infarction without obstructive coronary artery disease is characterized by significant heterogeneity, which requires additional examinations and differential diagnostics to identify the underlying causes of this condition.

Comparative analysis of laboratory data of 46 patients suffering from pneumonia caused by SARS-CoV-2 and 12 patients - pneumonia of bacterial etiology is given. It was established that in patients with COVID-19 compared to patients with bacterial pneumonia, the level of direct bilirubin is 84% more, and thrombocrit is three times more, which can indicate intravascular hemolysis and activation of the hemostasis system. Sex differences in laboratory indicators in patients with COVID-19, which go beyond the known limits of the physiological norm, were not detected. However, in men, hematocrit, hemoglobin, and plasma creatinine values were statistically higher than in women, but the amount of C-reactive protein in women was 5 times greater. However, these laboratory measures in COVID-19 have low prognostic significance. Therefore, conventional laboratory measures do not reveal clinic-critical differences in bacterial pneumonia and pneumonia caused by SARS-CoV-2. When conducting multifactorial analysis, it turned out that the laboratory indicators of patients suffering from bacterial pneumonia are not clustered and it is impossible to form predictor models from them. While laboratory indicators of patients suffering from pneumonia caused by COVID-19 form a directed pathogenetic response of the body as a whole, which causes multi-branch associated changes in homeostasis. Unfortunately, the amount of data available to us did not allow a qualitative discriminant analysis, which, with a very large amount of data, could lead to discriminant equations that are resistant to random emissions. This would allow, according to the available key individual laboratory indicators, to identify patients suffering from COVID-19 in the early stages already in the first hours of admission to the clinic.

Experimental study of specific activity and harmlessness of simultaneous application of five vaccines (abdominal, Zonne dysentery, viral hepatitis A, meningococcal and live yellow fever vaccine) in complex immunoprophylaxis of dangerous infectious diseases was carried out. It has been found that the simultaneous administration of these vaccines is safe and has high immunogenicity and protective efficacy for each infection not inferior to, and in some cases superior to, vaccines administered separately. In particular, the immunogenicity of vaccines against typhoid fever and viral hepatitis A administered jointly was four times higher than with their separate administration, which may indicate the presence of a certain adjuvant effect on the part of other vaccines, as well as the absence of antagonism in their joint use. It was revealed that complex vaccinations do not negatively affect the functional state of cells involved in the initial stage of immunogenesis. The absence of a negative effect of complex vaccinations on the components of nonspecific resistance of the body was almost completely confirmed in the conditions of infection of immunized animals with influenza virus, that is, in modeling heterologous infection. In addition, immunization with a complex of vaccines does not lead to allergic animals, which is confirmed by the absence of any manifestations of allergic reactions or anaphylactic activity.

Published: July 2021

This paper presents the summarized information on the mechanisms of neuroimmunoendocrine organism reaction to external adverse impacts (irrespective of their etymology), and on the key elements in these reactions development. It is found that adverse external factors are responsible for a change of an organisms functional state, involving neuroendocrinal and immune systems in the (stress) reaction formation. Neuroendocrinal and immune systems act like coordinators of the intersystemic and interorgan relations in the setting of both adaptive and pathological processes. The combination of feed-forward and feedback (positive and negative) connections controlled by hormones, neuromediators, neuropeptides, cytokines and their corresponding receptors, serves as the basis of neuroendocrinal and immune systems interaction. Through mediators and hormones, the neuroendocrinal system modulates the immune system, and the latter can modulate functions of the former due to its cytokine network. Along with humoral mechanisms, the vagal nerve which enables the reflectory control of immunity, is the key component of the system providing the functional unity of nervous and immune system. The conversion of immune signals to neural ones is done through activation of vagal afferent fibers by proinflammatory cytokines, whereas its efferent fibers, forming the cholinergic anti-inflammatory pathway, ensure the descending central nervous system effects which prevent the hyperactivation of innate and adaptive immune reactions. The body balance control is based on the integrative activity of nervous, endocrinal and immune systems both under normal and pathological conditions (traumas, infections, stress, physical and chemical exposures, etc). The systematization of information about the coordinated neuroimmunoendocrine interaction provides background for theoretical underpinning of the upcoming trends in search of means and ways to correct the negative influence of adverse external factors on a living organism.

Published: July 2021

Since SARS-CoV-2 first appeared in humans, the scientific community has tried to gather as much information as possible in order to find effective strategies for the containment and treatment this pandemic coronavirus. We reviewed the current published literature on SARS-CoV-2 with an emphasis on the distribution of SARS-CoV-2 in tissues and body fluids, as well as data on the expression of its input receptors on the cell surface. COVID-19 affects many organ systems in many ways. These varied manifestations are associated with viral tropism and immune responses of the infected person, but the exact mechanisms are not yet fully understood. We emphasize the broad organotropism of SARS-CoV-2, as many studies have identified viral components (RNA, proteins) in many organs, including immune cells, pharynx, trachea, lungs, blood, heart, blood vessels, intestines, brain, kidneys, and male reproductive organs. Viral components are present in various body fluids, such as mucus, saliva, urine, cerebrospinal fluid, semen and breast milk. The main SARS-CoV-2 receptor, ACE2, is expressed at different levels in many tissues throughout the human body, but its expression levels do not always correspond to the detection of SARS-CoV-2, indicating a complex interaction between the virus and humans. We also highlight the role of the renin-angiotensin aldosterone system and its inhibitors in the context of COVID-19. In addition, SARS-CoV-2 has various strategies that are widely used in various tissues to evade innate antiviral immunity. Targeting immune evasion mediators of the virus can block its replication in COVID-19 patients. Together, these data shed light on the current understanding of the pathogenesis of SARS-CoV-2 and lay the groundwork for better diagnosis and treatment of patients with COVID-19.
On Docetic Christology in Early Christianity. Pt. 2.1
Authors: Khosroyev Alexandr L.
Published: July 2021

According to the doctrine of so-called docetic Christology, earthly Jesus and heavenly Christ were two different persons; it was Jesus who suffered on the cross, Christ just entered Jesus body for a while and abandoned it before his death on the cross; consequently, the suffering of Christ was mere appearance. On the basis of some passages from Gnostic texts containing examples of docetic Christology, the author attempts here to trace the origin of that concept, starting with the New Testament (Pt. 1: Synoptic Gospels); in this part of the article, he deals with Pauls and Deutero-Pauline letters (Pt. 2). To be continued.

For the first time in the history of Russian Oriental Studies, the author conducts a comparative analysis of Safaite, Hismaite and Samudi texts and acquaints the Russian reader with the major deities of the North-Arabian pantheon. On the basis of this analysis, the work marks the two levels of Safaite Olympus: the cosmic one, represented by common Arab deities (al-Lat, Belshmin and Radw), and the tribal one, which includes the mythical characters of Salam, Yath, Dath and gadd-deities. In addition, the author observes the use of the reviewed theonyms by the denizens of pre-Islamic Arabia for the purposes of nomination.
“Grammar is the bridge to all knowledge”: short poems on the flyleaves in a manuscript of the metrical grammar
Authors: Pritula Anton D.
Published: July 2021

The article examines short poems written in the hand of ʿAbdīōʿ of Gāzartā, East Syrian patriarch (15551570), poet and scribe, in his own copy of Bar ʿEbrōyōs Metrical Grammar (12261286). The short works in question were added by the scribe himself between the larger texts, as well as on the flyleaves. The question of the relation of these poems, as regards their contents, to the main text of the Metrical Grammar is essential. This paper discusses the poetic features of these short texts, mainly quatrains, which illustrate the complex processes in the literary life of Christian communities during the Ottoman period. In addition, a general typology of these previously unknown texts is constructed.

Film uyarlamaları, özellikle edebiyattan uyarlananlar hem ana akım hem de bağımsız film endüstrilerinden gelen uyarlamaların miktarı nedeniyle son yıllarda hızlı bir şekilde büyümektedir. Bununla birlikte, bu çalışmaların odak noktası, genellikle edebi tarzın beyaz perdeye kolaylıkla uyarlanabilir olanların arasından en çok satan yapıtlara yöneliktir; ancak, uyarlama sürecinin tamamen farklı bir şekilde sonuçlandığı durumlar da vardır. Lev Tolstoy’un 1878 yılında kitap olarak yayınlanan Anna Karenina romanı, şimdiye kadar tiyatro, film, televizyon, bale, müzikal, opera ve edebiyat formlarında birden fazla kez uyarlanmıştır. Joe Wright’in 2012 yılında aynı isimle uyarladığı Anna Karenina, yönetmenin yaptığı cesur değişimler ile o zamana kadar romandan filme uyarlanmış diğer yapımlardan oldukça farklıdır. Uyarlama filmin yayınladığı çağın, çağın seyircisinin, sinemanın olanaklarının ve izleme pratiklerinin çeşitliliği de göz önünde bulundurulduğunda roman ve sinemanın farklı teknikler kullanarak hem seyircisine hem de okuruna nasıl bir dünya sunduğu inceleme konusu haline gelmektedir. Bu çalışma, Anna Karenina romanının 2012 yapımı uyarlaması ile birlikte ilk sesli film versiyonu olan 1935 yapımının romandan filme uyarlanırken ne gibi değişikliklere uğradığını dönemin romantik aşka bakışını da içine alacak şekilde içerik ve biçim analizi yöntemi ile değerlendirilmesini içermektedir.

Oyun, zaman ve yer kavramına bağlı olarak şekil değiştirerek evrensel boyutta varlığını her çağda sürdürmektedir. Dijitalleşme birçok alanda olduğu gibi oyunun da dönüşümünde rol oynamış ve oyunlar dijital ortamlarda varlık göstermeye başlamıştır. Sosyal ağ kullanıcıları dijital mecralarda genellikle oyunun katılımcısı olurken aynı zamanda oyun oynayanların da izleyicisi olabilmektedir. İzlence kültürünün bir aracı olan YouTube ise bu bağlamda işlevsel olarak kullanılmaktadır. Bu çalışma, YouTube’da çocuk oyun kanallarında dolaşıma sunulan oyun oynama videolarını ebeveynin onay ve kurgu süreci, çocuğun oyunun öznesi konumundan nesnesine dönüşmesiyle birlikte pasifize olma durumu ve sosyal ağlarda çocuğun kazanç aracı olarak kullanılmasıyla metalaşması noktasında sorunsallaştırmaktadır. Çalışma, işaret edilen çerçevede Goffman’ın dramaturji teorisi kapsamında abone sayısı yüksek ve aktif paylaşım yapan YouTube çocuk oyun kanallarının sosyal medyada benlik sunumunu analiz etmeyi amaçlamaktadır. Bu bağlamda, oyunun dijital çağdaki dönüşümüne odaklanılarak; çocukların videolarda sergiledikleri performansların ve kişisel vitrinlerine ait olan öğelerin ağ oluşturma pratiklerinde nasıl bir rol oynadığı değerlendirilmiştir. Analiz sonucunda, oyun alanının gösteri kültürünün bir parçası haline dönüşerek özünde var olan paylaşım ilişkilerinin kolektif süreçten uzaklaştığı, çocuk ile ebeveyn rollerinin akışkanlaştığı, gerçek ve hayal ayrımının da bulanıklaştığı saptanmıştır.

Published: July 2021

By analyzing a novel dataset on publications by the Inter-American Development Bank (IDB), we shed light on the extent to which the knowledge production of a multilateral development bank can reach its beneficiaries. We find that IDB publications are downloaded mostly in the American continent, with Colombia, Peru, Mexico and the United States leading the ranking. Moreover, during the COVID-19 pandemic downloads of IDB publications increased, both in the world and in Latin America and the Caribbean. Some characteristics of publications are significantly associated with higher numbers of downloads, such as the language of publications: documents in at least two languages or in Spanish only are downloaded more often than documents in English only, suggesting that it is important to disseminate research in the language of the targeted audience. As for the online discussion on the IDB, we find that mentions of the IDB touch different sectors important for development (especially modernization of the state, health, labor markets and financial markets), they increase when a document is published, and also when a loan is approved.

Authors: Ayano Mekonnen Shiferaw
Published: July 2021

The present study dealt with heat and mass transfer rate, and motile micro-organisms for convective micropolar nanofluid flow in a porous medium. The nanofluid contains the influence of both Brownian motion and thermodiffusion (thermophoresis). The problem considered finds applications in the areas of engineering such as reducing greenhouse effects and in the pharmaceutical applications enhancing mixing and slowing down settling particles can be mentioned. The numerical results are obtained and discussed. The results obtained suggest that micropolar fluids enhance the flow and decrease the temperature, nanoparticles concentration and gyrotactic microorganisms concentration profiles compared to viscous fluid. It is also noted that Hall parameter increases skin friction, the heat transfer rate, the mass transfer rate and density of the motile microorganisms.

Published: July 2021

This paper considered an existing subsea pipeline transporting an oil and gas flow, and proposed to find the best thermal insulating material and the required thickness of insulation necessary to meet an output temperature of 40℃ and a pressure of 2.4MPa so as to avoid flow assurance issues. MATLAB and PIPESIM software were employed to run the simulations of the temperature and pressure profiles along the considered pipeline. Data used for the simulations were obtained from open literature. Results obtained from our simulations in MATLAB are validated using PIPESIM software, measured values and prediction model from literature. The temperature model was then used to thermally design an insulation thickness for the 50 km long pipeline using three insulating materials which are: black aerogel, polyurethane and calcium silicate. Results from the analysis showed that the black Aerogel material with a critical thickness of 10.16 cm is most effective to satisfy the criterion design. The effect of the selected insulating material was also investigated on the phase envelop. Results shows that for proper insulation thickness the flowing fluid temperature can be maintained at a temperature above which no flow assurance issues can be observed.
A Study on Bituminous Coal Base Acid Ratio to the Slagging Factor at Large Scale Boiler
Authors: Samsudin Salmi , Aziz Nuraini Abdul , Hairuddin Abdul Aziz , Masuri Siti Ujila
Published: July 2021

Different types of coal have different characteristics and performances. In thermal coal plant, deposition of coal ash inside the furnace causes slag formation inside the boiler rear path and consequently reduces the heat transfer process and boiler efficiency. Besides, accumulation of ash on the boiler tube surfaces form layers of slags and blocks the flue gas flow out of the boiler. Therefore, the purpose of this study is to investigate the relationship between sub-bituminous coal base acid ratio towards the heat transfer process inside large-scale boilers. The base acid ratio for sub-bituminous coal is measured before firing inside large-scale boiler of studied the thermal plant which has a generation capacity of 700 MW. This study found correlation between high furnace rear path temperature (FRPT) that is observed to be above 800℃, with the build up of ash accumulation inside the boiler, for the studied coal. Thus, a high base acid ratio causes the accumulation of coal ash, thus reducing the heat transfer process which results in high FRPT of the boiler. Therefore, it proves that a base acid ratio is an indicator for coal performance during firing inside the boiler.

Published: July 2021

The significant interpretation of this model is to explore the influence of temperature-dependent heat source/sink on laminar free-convective flow in an annular porous region such as petroleum engineering, thermal technique and groundwater hydrology. For a unified solution of the Brinkman-Darcy model, the regulatory equations solved analytically by applying the variation of parameter technique in terms of Bessel's functions for the heat source and sink. Moreover, we have investigated the Variations of Darcy number, Heat source/sink and viscosity ratio in the presence of isothermal and constant heat flux sequentially. As a result, we received the critical value of the velocity for the radii ratio (R = 2.05 and 2.92) in both the cases of source and sink (S = 1.0 and Si = 0.1) respectively which is exhibited through the graphs. Further, the numerical outcomes present of the skin friction including volume flow with annular gap by the graphs as well as tables.

Published: July 2021

The involvement of non-linear convection effects in a natural convective fluid flow and heat transfer along with the effects of magnetic field in a porous cavity is studied numerically. Cu-water filled cavity of higher temperature at the left wall and lower temperature at the right wall. The governing equations are organized to achieve the required flow by using two-dimensional equations of energy, continuity and momentum. Vorticity-stream function based dimensionless equations are solved using the finite difference techniques. The results are discussed for various dimensionless parameters such as the Darcy number, non-linear convection parameter, Hartmann number, Rayleigh number and solid volume fraction of the nanoparticles. An augment in streamline velocity and convection heat transfer are observed by increasing the Rayleigh number, non-linear convection parameter and Darcy number. The non-linear convection parameter has a lesser effect on the lower Rayleigh numbers. Diminished streamline intensity and reduction in convection heat transfer are noted for an increase in the strength of the applied magnetic field irrespective of the non-linear convection parameter.

Miejsce Norwida w kulturze
Authors: Masłowski Michał
Published: July 2021

Norwida, nawet w obecnej fazie „postnowoczesności”, nie sposób sprowadzić do jednej formuły – jest raczej „konstelacją”, wymagając od czytelników „dyskusji nieustającej” problemów czasu. W centrum uwagi znajduje się człowiek w perspektywie dualistycznej, zmuszającej do poszukiwania syntezy materii z duchem, w perspektywie uniwersalizmu etycznego. Odwołuje się do „kopuły„monologu-nieustannie-się-parabolizującego”: kultury jako paraboli świata. Oryginalna estetyka „bieli” odwołuje się jakby do „łagodnego powiewu wiatru” z Biblii świadczącego o przejściu Boga i jest znakiem sprzeciwu wobec romantycznego uwielbienia wulkanu, któremu przeciwstawia wagę pracy. Filozofia ta, rozwinięta przez Brzozowskiego, Tischnera i Jana Pawła II doprowadziła do samoograniczającej się rewolucji „Solidarności” lat 1980-81, i ostatecznie do delegitymizacji i upadku komunizmu; po dwusetletnim panowaniu krwawego mitu rewolucji francuskiej – do przemiany paradygmatu przemian historycznych w świecie.
Norwid opracowywał romantyzm epoki przemysłowej, i przeciwstawiając się mesjanizmowi martyrologicznemu narodu wypracował swoisty „mesjanizm pracy”. Łączył go z wizją Kościoła człowieka, który „przepala glob, Sumieniem”. Kościołowi globu – przeciwstawiał parafiańszczyznę, „kościół zmieniony w salonik”. Liczy się człowiek a nie instytucja, dobro a nie Sakrament formalny. Chodzi o zmartwychwstawanie świata, a sztuka jest kościołem pracy. Bliska mu była perspektywa antropocentryczna, gdzie człowiek wezwany jest do „od-poczynania”, poczynania na nowo, w drugiej potędze – błędów przeszłości.
Swoim językiem i stylem Norwid konstruował nową warstwę społeczną – inteligencji – (Łapiński) jako rodzaj kopuły narodu, zwornika sumienia, świadomości zbiorowej. Tworząc rodzaj międzyosobowej transcendencji poziomej zarówno wzwyż jak wszerz społeczeństw.
Przeciwieństwem narodu ze swoją kulturą jest „cesarstwo” – źródło niewoli. Zniewalające zwłaszcza Europę Środkowo-Wschodnią. Szczególnie ważne jest starcie się cywilizacji azjatyckiej z chrześcijaństwem, czyli Europą zachodnią, „rzymską”. Poeta stawia jednak Słowianina w opozycji zarówno do Wschodu jak do Zachodu. Pada nacisk na procesualny a nie esencjonalistyczny charakter kultur narodowych.
Problem dialogiczności Norwida czy dominującego monologu dzieli badaczy. Ale Norwid jest w pewnym sensie Mistrzem, nauczycielem, który wciela Innego, wciela Mądrość własnym Głosem i Gestem. Istota Mądrości jest antropocentryczna, gdyż człowiek jest kapłanem, choć „bezwiednym / I niedojrzałym”, co obala podział na sacrum i profanum. Poprzez swój uniwersalizm etyczny Norwid przynosi odpowiedzi również na Oświeceniowy kryzys pojęcia uniwersalizmu racjonalności. Emancypacja jednostki nie powinna bowiem prowadzić do rezygnacji z przynależności, co jest wspólne modernizmowi Norwida i Europy środkowej (Ch. Delsol).
Kultury jako wyraz pragnienia zbiorowego kształtują odpowiedzialność i poczucie przynależności – są też odpowiedzią na kryzys indywidualizmu narcystycznego naszej epoki.
Norwid w poezji współczesnej. Formy obecności
Authors: Kudyba Wojciech
Published: July 2021

Artykuł odpowiada na pytanie o to, jaki kształt mają odniesienia do Norwida w tekstach poetów reprezentatywnych dla naszej współczesności. Przedmiotem opisu sąfunkcje takich intertekstualnych nawiązań – najpierw na terenie świadomości zbiorowej. Okazuje się, że w dwudziestoleciu międzywojennym i w czasie wojny sięgano do dzieł romantycznego mistrza na wszystkich etapach budowania własnej literackiej tożsamości. Czytano nie tyle teksty Norwida, ile raczej samych siebie w obliczu jego dzieł. Natomiast po 1956 roku obecność Norwida we wspólnotach pisarzy wyrasta raczej z potrzeb historyków literatury niż z rzeczywistych odniesień międzytekstowych. Ta tendencja obecna jest także na terenie badań twórczości pojedynczych autorów. Zdarza się – zwłaszcza wtedy, gdy mówimy o implicytnych śladach obecności Norwida w poezji współczesnej – że płaszczyzna relacji pomiędzy autorami nie jest przez interpretatorów przywoływana. Bywa, że dialog jako kategoria badawcza znika z pola ich obserwacji, a korpus dzieł Norwida jest traktowany jedynie kontekstowo – staje się pewnego rodzaju lustrem, które służy pełniejszej prezentacji jakieś właściwości twórczości wybranego autora lub motywu, który w niej występuje. Najważniejszych formy funkcjonowania autora Quidama w naszej współczesności to te, które osiągają wymiar spotkania (udanego lub nieudanego). Tak dzieje się w przypadku fascynacji poezją Norwida obecnej m.in. w tekstach Mieczysława Jastruna, Juliana Przybosia, czy też Tadeusza Różewicza.
„Taki to mistrz...”. Norwid w późnej liryce Tadeusza Różewicza
Authors: Halkiewicz-Sojak Grażyna
Published: July 2021

Na początku lat dziewięćdziesiątych XX w. Tadeusz Różewicz przygotowywał swój autorski wybór wierszy Norwida. Antologia nie powstała, ale śladem pracy nad nią jest Różewiczowski szkic pt. To, co zostało z nienapisanej książki o Norwidzie, a głębszym rezultatem – intensywna obecność nawiązań do poezji i biografii Norwida w liryce Różewicza z ostatniego ćwierćwiecza twórczości. Tematem artykułu jest rekonstrukcja dialogu poety z dziewiętnastowiecznym prekursorem podjętego w późnej twórczości (analizowana przy zastosowaniu niektórych aspektów koncepcji badania wpływów literackich Harolda Blooma): wskazanie miejsc wspólnych i kwestii polemicznych. Materiałem skupiającym uwagę autorki, poddanym analizie i interpretacji, są przede wszystkim wiersze ze zbiorów poetyckich Różewicza szczególnie wyraziście nasyconych nawiązaniami do Norwida: z Płaskorzeźby, szarej strefy, nożyka profesora, recyklingu, wyjścia. Konkluzje wynikające z szeregu szczegółowych, komparatystycznych interpretacji pozwoliły odnaleźć współbrzmienia tematyczne (temat egzystencjalnego braku i niedopełnienia, które dotykają i podmiot wierszy, i lirycznych bohaterów, predylekcja do kreowania postaci niezrozumianych, niepozornych, ale i wewnętrznie wydrążonych…), pokrewne predylekcje warsztatowe (np. eliptyczność, oszczędne i precyzyjne obrazowanie, przywiązywanie wagi do graficznego kształtu wiersza). Różewicz znajduje jednak w poezji Norwida i takie cechy, które go odpychają, jak np. poetyka wzniosłości czy zmysłowa powściągliwość i przesłanianie symbolicznymi obrazami dosłowności zła.

The water protection zone of the Tsimlyansk reservoir was chosen as the object of research. The subject of the study was the assessment of the intensity of manifestation of dangerous coastal processes of the reservoir: abrasion-latency, erosion activity. A method for monitoring erosion processes in water protection zones of water bodies using a software and hardware complex based on unmanned aerial vehicles and GIS technologies has been developed and tested. The optimal type of digital elevation models has been determined for assessing the density of the erosion net-work, determining the types of banks and the intensity of manifestation of abrasion and landslide processes, measuring the morphometric characteristics of erosional landforms. The types of erosional landforms were determined and the zoning of the territory of the water protection zone of the Tsimlyansk reservoir was carried out according to the density of the erosional dissection of the relief. Studies have shown that the predominant erosional forms of the relief of the water protection zone of the Tsimlyansk reservoir are ravines and gullies. The maximum average value of the density of the erosional network of the relief within the boundaries of the administrative districts of the reservoir coast falls on the Surovikinsky district. In the Kalachevsky district, the maximum value of the density of the erosion network is noted within the water protection zone of the Tsimlyansk reservoir.
Features of the Organization and Location of Gambling Zones in Different Countries of the World

The features of the organization and spatial placement of gambling zones in various countries of the world are considered. It is noted that this process (prohibition, restriction or widespread permission) is primarily influenced by the cultural characteristics of the population, which translates into the attitude of the authorities and administration in certain states towards the gambling business. As a result of the study, it was revealed that the states on this issue are divided according to civilization. In countries where Islam is the dominant religion, gambling is, as a rule, prohibited (although betting on races and dog fights is allowed). In countries belonging to the orbit of the Anglo-Saxon world (the vast majority of countries in America, Africa, Europe, Australia and Oceania), gambling is allowed everywhere, with some restrictions. In the monarchies of the East, gambling is allowed for foreigners, but the local population is prohibited from playing. In Russia, non-Islamic Asia (Orthodoxy, world oriental religions), measures have been taken to restrict the gambling business - it is allowed only in specially designated areas - gambling zones. This suggests a conclusion about the need for a compromise between society, government bodies and business when organizing these zones in the Russian Federation. At the same, it is worth taking into account and adapting foreign experience to Russian conditions.
