A forma dos perfis longitudinais dos cursos d’água associada à distribuição das planícies aluviais adjacentes permitem identificar trechos com predomínio de processos agradacionais e denudacionais nos sistemas fluviais. Este trabalho identifica trechos dos perfis longitudinais dos rios a montante do Parque Estadual de Terra Ronca, no nordeste do estado de Goiás, que possuem tendências diferentes para transferência de sedimentos para jusante. Os rios cujos perfis longitudinais mais atenuam o potencial de transferência de sedimentos são: o São Vicente, da Lapa e Angélica. A forma dos perfis e a distribuição das planícies aluviais estão intrinsecamente ligados aos compartimentos geomorfológicos da área do Parque Estadual de Terra Ronca e à evolução do relevo regional, influenciando o transporte de sedimentos da rede de drenagem.The Role of the Longitudinal Profile in the attenuation of the Potential of Transport of Sediments in Watersheds: the case of the Terra Ronca State Park (GO), Brazil A B S T R A C TThe shape of the longitudinal profiles of rivers associated with the distribution of the adjacent floodplains allows identifying sections with predominance of aggradational and denudational processes in the fluvial systems. This paper identifies stretches of the longitudinal profiles of the rivers upstream of the Terra Ronca State Park, in the northeast of the state of Goiás, which have different trends to transfer of sediments to downstream. The rivers whose longitudinal profiles more attenuate the sediment transfer potential are: São Vicente, Lapa and Angélica. The shape of the profiles and the distribution of alluvial plains are intrinsically linked to the geomorphological compartments of the Terra Ronca State Park’s area and the evolution of the regional relief, influencing the sediment transportation of the fluvial drainage network.Keywords: sediment transportation, alluvial plains, geomorphological compartmentation.

AbstractOn continents, besides lake and bogs, we observe non-continuous sedimentation where particular layers or whole members represent time intervals of various lengths separated by breaks of different origin. Both, fluvial and slope sediments or forms carry climatic signal. By analyzing sources of sediments, factors of transfer, duration of deposition we reconstruct climatic changes (mainly temperature, precipitations and circulation of water). We order the collected records after age and tracing longitudinal profiles of slopes and river valleys. The slopes and valley floors inform us about spatial differentiation of extreme climatic-hydrological events and on their reflection in degradation or aggradation. All this information sums up the records collected in various projects or commissions like IGCP-158 and GLOCOPH (Starkel ed. 1982–1996; Starkel et al. 2007), Climatostratigraphy of the Holocene of Polish territory (Starkel et al. 2013) as well INTIMATE (Starkel et al. 2015; Gębica et al. 2015). It may be concluded that fluctuations in temperature combined with expansion of permafrost were the leading factors in transformation of landscape of analyzed area of Southern Poland during last cold stage, which is in contrary to the Holocene, when variations in humidity especially in frequency of extreme events played a leading role. The continental records very well express the role of transitional phases.

Do So

SummaryThe role of intravascular coagulation in the production of the generalized Shwartzman phenomenon has been evaluated. The administration of endotoxin to animals prepared with Thorotrast results in activation of the coagulation mechanism with the resultant deposition of fibrinoid material in the renal glomeruli. Anticoagulation prevents alterations in the state of the coagulation system and inhibits development of the renal lesions. Platelets are not primarily involved. Platelet antiserum produces similar lesions in animals prepared with Thorotrast, but appears to do so in a manner which does not significantly involve intravascular coagulation.The production of adrenal cortical hemorrhage, comparable to that seen in the Waterhouse-Friderichsen syndrome, following the administration of endotoxin to animals that had previously received ACTH does not require intravascular coagulation and may not be a manifestation of the generalized Shwartzman phenomenon.

Revolutionary Politics

This book is designed to remove Peter Kropotkin from the framework of classical anarchism. By focusing attention on his theory of mutual aid, it argues that the classical framing distorts Kropotkin's political theory by associating it with a narrowly positivistic conception of science, a naively optimistic idea of human nature and a millenarian idea of revolution. Kropotkin's abiding concern with Russian revolutionary politics is the lens for this analysis. The argument is that his engagement with nihilism shaped his conception of science and that his expeditions in Siberia underpinned an approach to social analysis that was rooted in geography. Looking at Kropotkin's relationship with Elisée Reclus and Erico Malatesta and examining his critical appreciation of P-J. Proudhon, Michael Bakunin and Max Stirner, the study shows how he understood anarchist traditions and reveals the special character of his anarchist communism. His idea of the state as a colonising process and his contention that exploitation and oppression operate in global contexts is a key feature of this. Kropotkin's views about the role of theory in revolutionary practice show how he developed this critique of the state and capitalism to advance an idea of political change that combined the building of non-state alternatives through direct action and wilful disobedience. Against critics who argue that Kropotkin betrayed these principles in 1914, the book suggests that this controversial decision was consistent with his anarchism and that it reflected his judgment about the prospects of anarchistic revolution in Russia.

ABSTRACT The role of luteinizing hormone (LH) for the maintenance of pregnancy, parturition and lactation was investigated by immunological and histochemical methods in the rat. Neutralisation of endogenous rat-LH with Rabbit-Anti-Bovine-LH-Serum (selective hypophysectomy) from days 7-12 of pregnancy resulted in reabsorption of the foetuses and the reappearance of strong 20α-hydroxysteroid-dehydrogenase (20α-OHSD) activity in the corpora lutea (CL) of pregnancy, which normally show no such activity at that time. This effect could be prevented in part by concurrent pregnenolone administration and fully by progesterone, but was not influenced by oestrogen or prolactin. It is concluded that in early pregnancy LH is the main luteotrophic hormone in the rat even though prolactin might act synergistically with it. Antiserum treatment after the 12th day of gestation had no influence on the state or duration of pregnancy or on parturition. LH-injections during the first half of pregnancy had no luteolytic effects i. e. they did not activate 20α-OHSD activity. After day 16 they advanced the reappearance of the enzyme, but delayed parturition or resulted in stillbirths. Neither LH nor antiserum seemed to alter lactation. Since progesterone prevented both the termination of pregnancy and the recurrence of 20α-OHSD activity, it should have some regulatory properties on the enzyme. It is discussed whether the gonadotrophin-dependent progesterone level could regulate the 20α-OHSD activity rather than result from it.

The aim of the article was to defi ne the role of the radioactive environment contamination in the formation of ecosystem services strategy. Methods. Monographic, systemic and structural, factor analysis, abstract and logical research methods have been used. The data from the State Statistics Service of Ukraine, the Ministry of Agrarian Policy and Food of Ukraine, the Ministry of Ecology and Natural Resources of Ukraine, materials of scientifi c researches, international materials and reports and other literary sources on the issues investigated have been used as an information base. Results. Retrospective analysis of sources and state of radioactive eco- systems contamination was conducted and the priority steps in developing the concept of ecosystem services in conditions of radiation contamination were found. Conclusions. The current socio-ecological paradigm of the transition from environmental use to environmental management should be refl ected in the relevant envi- ronmental management mechanisms. Currently, when assessing the state of ecosystem services in Ukraine and worldwide one must take into account the changes in food demand of residents of radioactively contaminated areas, the exploitation of radioactively safe ecosystems growth, their overload and degradation. All of this re- quires an inventory of ecosystem services by type, region, consumers, etc. and the formation of a state register of ecosystem services with a clear assignment of area of responsibility for appropriate natural ecosystems. This will help to make the economic evaluation of different ecosystem services and mechanisms of charges for ecosystem services.
