The frequency and character of community-acquired pneumonia comparison before and during the COVID-19 epidemic in the multi-specialty hospital
No full textBACKGROUND: The 2019 coronavirus disease outbreak (COVID-19) quickly swept the world in just a month. Polymerase chain reaction (PCR) is used in the diagnosis of this disease, but this test has limitations related to false negative results, as well as PCR is a time-consuming procedure. Under these conditions, chest computed tomography (CT) can become one of the main methods in the Clinician’s Arsenal used for early detection of COVID-19 in patients who first seek medical help. AIMS: comparison of the frequency of community-acquired pneumonia and its characteristics according to CT data before and during the COVID-19 epidemic and study of the possibilities of their timely detection and differential diagnosis. MATERIALS AND METHODS: A retrospective analysis of chest CT scans results was performed in Davydovsky hospital (Moscow) from April 1 to April 17, 2020. It included all patients diagnosed with viral pneumonia at the CT. All patients with suspected diagnosis of viral pneumonia underwent PCR testing. Retrospective analysis of chest CT data from patients admitted to the hospital with suspected pneumonia for the same period in 2019 was taken as a comparison group. RESULTS: For the period from April 1 to April 17, 2020 according to chest CT, pneumonia was diagnosed in 140 cases, of which 65 (46.4%) were described as viral, compared with the same period in 2019 − 7 diagnoses of viral pneumonia (10.3%) were described a significant increase in cases of viral pneumonia (5.723; p
USSR ETHNIC POLICY IN PRE-WAR PERIOD (1938-1941)
No full textIn the article the author analyses the main aspects of the Soviet ethnic policy course during the period preceding the Great Patriotic War (1938-1941): strengthening of the Russian ethnic factor, formation of the ‘Soviet patriotism’concept, propaganda of ‘the friendship of peoples’, as well as the conjugation of the new directions of the ethnic policy and ‘the proletarian internationalism’. The author shows that the ethnic policy implemented during the mentioned period laid the basis for moral mobilizing of the Soviet people during the war, though this policy was not brought to the conclusion
Τὰ Ὅπλα Τῶν Γεφυρέων Wojny perskiej: Herodot o wygnaniu barbarzyńców z Europy i kwestia kompletności pierwszych „Dziejów”
No full textW artykule poddano dyskusji problem zawartości dzieła Herodota. Zadano pytanie, w jakim stopniu „Ojcu historii” udało się wypełnić zamierzenia. Pojawił się problem, czy dzieło Herodota dotarło do naszych czasów w całości? Analizując problem ostatniej partii dzieła, .Autor pracy zwraca uwagę na fragment Herodota IX.121, w którym odniesiono się do kwestii przekroczenia granic Europy przez Barbarzyńców.The article discusses the principal “Herodotean question” of the completeness of the work done by the historian. How well did Herodotus manage to accomplish his design? Should we regard his work in the form it has reached us as complete and integral? Or does it end abruptly at the events of 479/8 BC, despite “the Father of History” having planned to continue his account of the Greek-Persian wars? Over the last century and a half, pluralism in the views the researchers on the issue of the completeness of Herodotus’ work has emerged. The author ventures some observations on the finale of the The Histories and draws our attention to the passage Hdt. 9.121 in which Herodotus emphasizes the fact that the barbarians transgressing the geographical boundaries of Europe had been punished: the cables of the bridges which the Persians had used to tie Asia and Europe were taken to Hellas by the victors. According to the author, the historian’s testimony τὰ ὅπλα τῶν γεφυρέων ὡς ἀναθήσοντες ἐς τὰ ἱρά symbolizes the end of the war against the Barbarian, hence, the accomplishment of Herodotus’ design – the completion of the account of “great and marvellous deeds done by Greeks and foreigners and especially the reason why they warred against each other”
Dynamics of Grain Yields in European Russia in the 19th — Early 20th Centuries: The Extent of Knowledge of the Issue
No full textThis article deals with the problems of research in national science of the dynamics of grain yields in European Russia between the nineteenth and early twentieth centuries.
For the purpose of the article, the author refers to crop statistics. Disputes about their reliability have been going on for about two hundred years, however, no irrefutable evidence of their unreliability has been presented. This is also true about the discussion of the early twenty-first century, where the source was criticised by B. N. Mironov and M. A. Davydov, and their opponents were S. A. Nefedov, A. V. Ostrovsky, and I. A. Kuznetsov.
Interest in the dynamics of productivity emerged in the late nineteenth century. The focus of attention was the question of whether there was an increase in productivity in the period under review or not. At the turn of the twentieth century, A. F. Fortunatov and R. I. Preger maintained that productivity had increased, and I. Kh. Ozerov argued that it had not.
In the 1920s, three views on the character of yield dynamics formed. V. G. Mikhailovsky and M. I. Semenov talked about a growth in yield combined with cyclical and random fluctuations. F. Cherevanin wrote that the yield in European Russia changed exclusively cyclically. V. M. Obukhov and A. L. Weinstein argued that grain yields grew, obscured by random fluctuations, in the absence of a cyclical component.
It was the third point of view that prevailed with B. S. Yastremsky, A. S. Nifontov, A. V. Ostrovsky, V. G. Rastyannikov, and I. V. Deryugina following it. Only N. O. Voskresenskaya questioned the widespread increase in productivity.
However, the previously used research methods (interval enlargement, correlation-regression analysis) are imperfect, and therefore the findings require rechecking using methods that are not in demand by national science for the analysis of crop statistics (hypothesis of the averages, Foster — Stewart method), which will help to better understand the nature grain yield dynamics in European Russia in the nineteenth and early twentieth centuries
Ethnic Factor in Nazi Occupation Policy During the First Stage of the Great Patriotic War (June 1941 - November 1942)
No full textIn the article the author analyzes the main aspects of the Nazi government ethnic policy implemented on the occupied territory of the Soviet Union during the first stage of the Great Patriotic War (June 1941 - November 1942) in the «civic» sphere (local administering, regulating ethno-cultural activities, mobilizing labor force, etc.). The authour shows the peculiarities of using the «ethnic factor» by Nazi occupants, and identifies its main trends, including promotion of nationalism, separatism, and russophobia, as well as the contradictions of the Nazi policies in the matter of granting self-government to the peoples of the Soviet Union
ETHNOPOLITICAL CONSEQUENCES OF GERMAN OCCUPATION POLICY IN USSR (1944-1945)
No full textThe article analyses the main outcomes and consequences of the Nazi occupation of the Soviet territory in its ethnic aspect: the extent of pro-German sentiments; the surge of ethnic conflicts and anti-Soviet insurgency; the issues of collaborationism and ‘non-return’ of Soviet citizens. The author shows that at the final stage of the Nazi occupation there became obvious the failure of the German policy and propaganda on the occupied Soviet territory, which was based on the principles of chauvinism and incitement of ethnic hatred
„Archeologia” historiografii jako retoryczna gra. O porównaniu greckich autorów w „Liście do Pompeiusza” Dinizjosa z Halikarnasu
No full textDionysius of Halicarnassus in his short theoretical treatise entitled “A Letter to Pompeius” (Epistula ad Pompeium) presents an exciting discussion on rhetoric mastership and scholarship written in an epistolary genre. The treatise begins with critical remarks Dionysius once addressed to Plato. The author admits to his addressee (Cn. Pompeius Geminus) that he is enchanted by Plato’s dialogues. From the trio of Greek speech-makers who are recognized as the most brilliant in this respect – Isocrates, Plato, and Demosthenes (such was Dionysius’s selection) – the Halicarnassean rhetorician deliberately dwells on Plato (Lysias, Isocrates, Demosthenes and other Greek orators are the subject of his other aesthetic works). Embarking on a wider discussion, Dionysius repeatedly points out that these studies are always aimed at establishing the truth. The longest chapter, 3 compares works of the first Greek historians and the mastery of their style. Dionysius points out the rivalry of the many masters of the genre, but the main characters of the chapter are Herodotus and Thucydides. The “father of history” (Dionysius’ contemporary and paragon) surpasses the Athenian historian on all counts examined by the author. This article examines συγγραφεύς / συγγραφεῖς or συγγραφή occurring in the Pomp. by Dionysius of Halicarnassus. The rhetorician, when referring to Herodotus, Thucydides (ch. 3), Theopompus (ch. 6), Hellanicus, Charon (3.7) and the Greek historians en masse (6.7), calls them “syngraphers”. Dionysius uses the word συγγραφή only as applied to historical works of Theopompus of Chios (6.2, 3, 6). The article also draws upon the Halicarnassian philologist’s other works in which he mentions syngraphers-historians, who are set off against poets and orators. Dionysius regards the words συγγραφεύς, ὁ ἱστορικός, ἱστοριογράφος as equivalent and interchangeable. In this work, Dionysius examines different styles of ancient writers. Here, by examining the works by the authors of the 5th and 4th centuries BC (written three to four centuries before his time) he seems to be performing a peculiar experiment of theoretical “archaeology”. But the rhetoric and philological “archaeological” study conducted by Dionysius of Halicarnassus reveals not only his scholarly interest in the analysis of works of the writers of the past, but also his focus on the present – both in literary and cultural aspects. Plato is under the influence of Thucydides, but Thucydides is inferior to Herodotus, Herodotus produces works that surpass those of Charon and Hellanicus, while Theopompus is superior in style to Demosthenes himself and surpasses Isocrates – the “most brilliant” rhetoricians of the past. By presenting this gallery of names, Dionysius shows comparison as agon – of styles, genres, authors, their subject matters, intensive narrative, and he himself contends with the writers of the past. Seeing mastery of rhetoric as a peculiar agon stretching over centuries and across the agon of rhetoricians, philosophers and historiographers, Dionysius identifies the circle of best writers, and himself joins it. He claims that in the scholarly rhetoric “the truth is dearer still” and establishes the criteria to judge the classic writers. And the critic realizes that he will be judged according to the same (his own) criteriaDionizjos z Halikarnasu w teoretycznym traktacie zatytułowanym „List do Pompejusza” zawarł dyskusję na temat retorycznego mistrzostwa i nauki. Traktat rozpoczynają krytyczne uwagi Dionizjosa, adresowane do Platona. Autor przyznaje jednak, iż jest zachwycony dziełami Platona. Pośród trzech greckich mówców, uznawanych za najwybitniejszych – Izokratesa, Platona, Demostenesa – Dionizjos z Halikarnasu celowo studiuje Platona. Prowadzi szeroką dyskusję. Dionizjos wielokrotnie podkreśla, że wskazani autorzy mają na celu ustalenie prawdy. Najdłuższy rozdział oznaczony jako 3, dotyczy historyków greckich i stylu ich prac. Dionizjos zauważa rywalizacje mistrzów, ale głównymi bohaterami rozdziału stali się Herodot i Tukidydes. Dinozjos zauważa, że „ojciec historii” przewyższa ateńskiego historyka. Prezentowany artykuł dotyczy użycia słowa συγγγραφεύς. Słowa tego retor użył w odniesieniu do Herodota, Tukidydesa, Hellanikosa i innych historyków. Dionizjos wskazuje na styl autorów, tematykę ich prac
