Microagglutination tests were used to show the relationship of a nongroupable strain of Neisseria meningitidis (RAS-10) to other serological groups. RAS-10 antiserum has been prepared and studied for the first time. Antibodies to the RAS-10 strain were shown to be present in many grouping antisera obtained from different sources. These antibodies were absorbed from antisera to heterologous sero-groups with the RAS-10 strain. This procedure was shown to make antisera more specific by eliminating serological cross-reactions and false grouping of RAS-10 strains. Antisera before and after absorption with RAS-10 cells were studied by using double diffusion in gels. An antigen-antibody precipitation line for the RAS-10 meningococci was shown to be removed by this procedure. Antiserum to group 29E meningococci was absorbed with group Z cells, and precipitation lines for Z cells were removed. Group 29E antiserum agglutinated group 29E and group Z cells in the slide agglutination test but was specific for group 29E cells in this test after absorption with group Z cells.

Впервые в мире создана популяция зубров на территории 60 градусов северной широты. В новых климатических условиях разведения и сохранения зубров определены и проанализированы факторы существования вида на севере Европейской части РФ. Выявлены признаки, динамика численности, которые являются составной частью системы, предназначенной для управления биоразнообразием. Интродукция, являясь процессом введения в экосистему нехарактерных для нее видов, может усиливать изменения биоценозов как положительно, так и отрицательно. Насколько быстро и успешно проходит процесс адаптации заселенного вида, и усматривается его влияние на окружающую среду зависит дальнейшее существование зубров и в целом биоразнообразия. В статье обсуждаются вопросы взаимоотношения зубров с другими видами копытных и хозяйственной деятельностью человека, а также дальнейшим использованием зубров в сельскохозяйственном производстве. Пластичность зубров, выявление изменений и их анализ при вселении видов в новые условия обитания необходимы не только для определения развития или деградации биоценозов и в целом экосистемы, но и прогноза социально-экономических последствий интродукции как одного из методов сохранения редких и исчезающих видов фауны.For the first time in the world, a bison population has been created in an area of 60 degrees north latitude. In the new climatic conditions of breeding and preservation of bison, the factors of the species existence in the north of the European part of the Russian Federation are identified and analyzed. The signs, dynamics of abundance, which are an integral part of the system designed to manage biodiversity are identified, since the preservation of biological diversity on the planet is one of the main problems of our time. Introduction, being the process of introducing non-typical species into an ecosystem, can enhance changes in biocenoses, both positively and negatively. The question posing sounds especially when it comes to such a large hoofed animal as the European bison. How quickly and successfully the process of adaptation of the universe takes place and its environmental impact is seen depends on the continued existence of bison and biodiversity in general. The article discusses the relationship of bison with other types of ungulates and human activities, as well as the further use of bison in agricultural production. How these issues will be resolved positively depends on the future of these animals. Thus, the plasticity of bison, the identification of changes and their analysis, with the introduction of species into new habitat conditions is necessary not only to determine the development or degradation of biocenoses and the ecosystem as a whole, but also to predict the socio-economic consequences due to the introduction as one of the methods of preserving rare and endangered species of fauna.

Abstract This article addresses in depth for the first time the irregularly shaped canvases known as tableaux chantournés (cut-out paintings) that were produced in vast numbers by leading academicians between the 1730s and 1750s and occupy a tenuous place between fine and applied or decorative arts. Through an examination of the term’s first uses in regard to painting and eighteenth-century critics’ responses to these works, tableaux chantournés are positioned as a means of rethinking the extraction of painting from a richer visual field and the relationship of this medium-specific agenda to the historiography of the rococo.

This article examines the life and times of Richard Scheringer, an army officer and supporter of Adolf Hitler who became famous during the early 1930s for his high-profile conversion to communism. Known in the closing years of the Weimar Republic as a point-man for Communist efforts to win support from the radical right, Scheringer survived the Third Reich to become a leading figure in the postwar Communist Party. His well-documented but little-studied career, bridging critical caesurae of modern Germany history, highlights the unique political constellation of the interwar period, demonstrating fundamental continuities in the relationship of German communism to the nation before and after 1945.

The relationship of the manuscripts of the Middle-English poem Ipotis has been studied in detail by Dr. Hugo Gruber on the basis of the nine mss. known to him. In addition to these there are five others, four of which are printed for the first time below. One of these, unfortunately a fragment, is of the greatest importance, since it carries back the date of the poem at least fifty years. On the basis of the earliest manuscript known to him—ms. Vernon, written about 1385—Gruber assigned the Ipotis to the second half of the fourteenth century. But in the light of the new evidence, the composition of the poem is pushed back to the very beginning of the century.

AbstractIn 1789 in Leipzig, a slim pamphlet of 128 pages appeared that sent shock waves through the German republic of letters. The pamphlet, bearing the title Mehr Noten als Text (More notes than text), was an ‘exposure’ whose most sensational element was a list naming numerous members of the North German intelligentsia as initiates of a secret society. This secret society, known as the German Union, aimed to push back against anti-Enlightenment tendencies most obviously manifest in the policies promulgated under the new Prussian king Frederick William II. The German Union was the brainchild of the notorious theologian Carl Friedrich Bahrdt (1741–92). But who was responsible for the ‘exposure’? Using material culled from several archives, this article pieces together for the first time the back story to Mehr Noten als Text and in doing so uncovers a surprisingly heterogeneous network of Freemasons, publishers, and state officials. The findings prompt us to reconsider general questions about the relationship of state and society in the late Enlightenment, the interplay of the public and the arcane spheres and the status of religious heterodoxy at this time.

The predictability of maximal O2 intake (max Vo2) was studied in four groups of normal men, 18–24 years of age. Prediction of max Vo2 was made from pulse rate and Vo2 at a single submaximal workload at an ambient temperature of 78 F by use of the nomogram of Åstrand and Ryhming (1954) and underestimated actual max Vo2 by 27 ± 7% and 14 ± 7% in a sedentary group, before and after 2frac12–3 months of physical training, and by 5.6 ȁ 4% in a group of ten endurance athletes. Accuracy of prediction in all groups varied with approximation of pulse rate to 128 beats/min at 50% of max Vo2. Nonspecific stresses increased predictive errors in all groups. Constants b (slope) and A (intercept) in the regression equation Vo2 = bP – A (where P is pulse rate), were determined from Vo2 and pulse measured at four submaximal workloads requiring 13–28 ml O2/kg min. Prediction of max Vo2 by extrapolation of the slope to maximal pulse rate resulted in underestimation of 700–800 ml O2/min. Removal of 14% of circulating hemoglobin decreased max Vo2 by 4% but there was no change in pulse rates or predicted max Vo2. The relationship of RQ to V22 during work provided no reliable basis for prediction of max Vo2. exercise pulse rate, oxygen intake, relationship; pulse rate, oxygen intake relationship in exercise; metabolic rate, maximal aerobic prediction of; aerobic metabolic rate, maximal, prediction of; phlebotomy, effect on maximal oxygen intake, pulse rate; blood loss, effect on maximal oxygen intake, pulse rate; training, effect on maximal oxygen intake, pulse rates; physical conditioning, effect on maximal oxygen intake, pulse rates Submitted on October 4, 1963

For the first time, a mycological analysis of outdoor urban environment (air, leaves, sealed surfaces) was carried in the cities of subarctic (Murmansk) and temperate (Moscow) climatic zones. The chemical composition of dust deposited on leaves of dominant tree species was taken as an indicator of the air quality. Assessment of the complex impact of factors (climate zone, type of substrate, anthropogenic load) on the quantitative and qualitative parameters of mycobiome was performed. Compared to Moscow, Murmansk was characterized by an increased number and concentrations of pollutants in the deposited dust. The number of culturable airborne fungi in Murmansk was substantially lower than in Moscow. Half of the species belonged to the opportunistic in both cities. Most dangerous opportunistic fungi were absent in the air of recreational zones but present on leaves surface and in road dust in all assessed zones of the cities. Dust chemical composition affected the diversity of fungi species. While the relationship of biological parameters with concentration of potentially toxic metals was generally negative, Cd increased the fraction of opportunistic fungi in road dust. The study revealed an importance of substrate in determining the sensitivity of outdoor mycobiome to pollution and highlighted its biological characteristics sensitive to climate.

Introduction: at present the reader’s audience is particularly interested in creative experiments in which the historical fate of the Russian peasantry in the «turning» eras is artistically comprehended. The article is devoted to the study of the problem-thematic range of modern Mordovian historical prose. The subject of analysis is the peculiarity of the reception of the period of collectivization and dekulakization in the story by Erzyan prose writer A. Doronin «A Wolf Ravine». Objective: to reveal the features of the artistic reconstruction of the events of the 1930s, the modeling of the relationship between a man and society in the story by A. Doronin «A Wolf Ravine».Research materials: the story by A. Doronin «A Wolf Ravine». Results and novelty of the research: the historical story « A Wolf Ravine » for the first time becomes the object of scientific understanding and is introduced into the context of Finno-Ugric literary criticism. A. Doronin artistically interprets the real events and circumstances of the resettlement of dispossessed peasants of the Volga region to the uninhabited steppes of Kazakhstan. As a result of the study, we conclude that the actualization of this problem-thematic cluster is due to the creative concept of the historical writer; the individual author’s approach to the reconstruction of historical narrative can be traced in the writer’s desire to realistically reveal the relationship of personality and society in the tragic 1930s; to analyze intentions of people and of the psychological states of the characters. Problems of a sociopolitical nature, actualized in the story, are filled with philosophical, axiological content, and lead to a multi-faceted understanding of the «man and history» problem.

Abstract. The aim of this work is to investigate the relationship between indicators of cicatricial digestion and linearity of cows. Methods. The research was carried out in the breeding enterprises of the Sverdlovsk region on the livestock of Ural-type cows. Cicatricial fluid was collected with an oropharyngeal rubber probe, and a wooden yaw was also used. Cicatricial content was assessed at the Chelyabinsk Interregional Veterinary Laboratory. The pH value was determined by the electrometric method, VFA – in the Markgam apparatus, ammonia – by the microdiffusion method. Ciliates – in Goryaev’s chamber and under a microscope, bacteria – under a microscope with the addition of sodium chloride solution. Statistical data processing was carried out in the Microsoft Office Excel 2010 program. Results. In terms of the number of ciliates and bacteria in the rumen fluid, the Montwick Chieftain cows, characterized by high productive qualities, had an advantage. In terms of pH and VFA, the Vis Back Ideal line was the best. There were no significant differences between the groups in terms of the amount of ammonia in the rumen. The best animals from the point of view of influence on cicatricial metabolism were the animals of the Vis Back Ideal and Montwick Chieftain lineage. Scientific novelty. Studies have shown that linearity is associated with cicatricial digestion in cows. The relationship of bull lines with indicators of cicatricial metabolism of cows has been determined for the first time. The food in the rumen is digested due to the action of bacteria, ciliates, and fungi. An environment has been created in the rumen for the active development of microflora. Bacteria are able to synthesize amino acids and vitamins. The proventriculus can contain up to 50 species of ciliates.

Adolescent subcortical structural brain development might underlie psychopathological symptoms, which often emerge in adolescence. At the same time, sex differences exist in psychopathology, which might be mirrored in underlying sex differences in structural development. However, previous studies showed inconsistencies in subcortical trajectories and potential sex differences. Therefore, we aimed to investigate the subcortical structural trajectories and their sex differences across adolescence using for the first time a single cohort design, the same quality control procedure, software and a general additive mixed modeling approach. We investigated two large European sites from ages 14 to 24 with 503 participants and 1408 total scans from France and Germany as part of the IMAGEN project including four waves of data acquisition. We found significantly larger volumes in males versus females in both sites and across all seven subcortical regions. Sex differences in age-related trajectories were observed across all regions in both sites. Our findings provide further evidence of sex differences in longitudinal adolescent brain development of subcortical regions and thus might eventually support the relationship of underlying brain development and different adolescent psychopathology in boys and girls.
