It is known that the state of Pernambuco will suffer impacts on precipitation due to the increase in CO2 in the atmosphere. In an attempt to contribute to the prognosis of these impacts, this study aims to develop a model that makes a prognosis or creates future scenarios for the state of Pernambuco. For that, the autoregressive method of moving averages, ARIMA, was used. The model adjustment was performed using the normalized Bayesian information criterion function. The results showed that the developed model presents a strong fit. The model was better adjusted for the Agreste and West of the state. The model projects a precipitation decrease trend for the western state of Pernambuco of approximately 15% below the historical average until 2027. The model projected rainfall above the historical average for the Agreste of Pernambuco, of approximately 17%, until 2027. It concludes It is believed that rainy years will occur more frequently in the Agreste region of Pernambuco, and we will have more frequent dry years in the west of the state. In applying the results of this study and simulation with the model SUPER-System of Hydrological Response Units for Pernambuco, it is concluded that there will be more flood peaks in the Mundaú basin until 2027.

The article is devoted to the analysis of the changes in economic and legal context for commercial application of intellectual property created under federal budgetary financing. Special attention is given to the role of the state and to comparison of key elements of mechanisms for commercial application of intellectual property that are currently under implementation in Russia and in the West. A number of practical suggestions are presented aimed at improving government stimuli to commercialization of intellectual property created at budgetary expense.

What is an underground? Is it possible to embed this particular way of life into any definition? After all, even underground did not have the need to define itself at the beginning. The presented text represents a brief reflection of the development of underground in Czechoslovakia; attention is paid to the impulses from the West, which had a significant influence on the underground. The text focuses on the key events that influenced the underground. For example, the “Hairies (Vlasatci)” Action, which took place in 1966, and the State Security activity in Rudolfov in 1974. The event in Rudolfov was an imaginary landmark and led to the writing of a manifesto that came into history as the “Report on the Third Czech Musical Revival.”

The paper deals with the organization and decisions of the conference of the Minister-Presidents of German lands in Munich on June 6-7, 1947, which became the one and only meeting of the heads of the state governments of the western and eastern occupation zones before the division of Germany. The conference was the first experience of national positioning of the regional elite and clearly demonstrated that by the middle of 1947, not only between the allies, but also among German politicians, the incompatibility of perspectives of further constitutional development was existent and all the basic conditions for the division of Germany became ripe. Munich was the last significant demonstration of this disunity and the moment of the final turn towards the three-zone orientation of the West German elite.

This short essay focuses on three issues: how science studies may facilitate the rapprochement between the philological study of scientific texts and Middle East history; how it may help us reconsider ambiguous if not “black-boxed” terms such as the “state,” “Islam,” and the “West”; and finally, how it may build thematic and theoretical bridges with other histories and geographies of science currently emerging from a more global, and not merely local, perspective.

Key Points In almost all U.S. states, pregnancies reported as occurring at the right time or being wanted sooner than they occurred comprised the largest share of pregnancies in 2017, though proportions varied widely by state. The proportion of pregnancies that were wanted later or unwanted was higher in the South and Northeast than in other regions, and the proportion of pregnancies that occurred at the right time or were wanted sooner was higher in the West and Midwest. From 2012 to 2017, the wanted-later-or-unwanted pregnancy rate fell in the majority of states. However, no clear pattern emerged for any changes in the rate of pregnancies that were reported as wanted then or sooner or in the rate of those for which individuals expressed uncertainty.
