The plate archive of the Sternberg Astronomical Institute
Program available at: http://www.imcce.fr/hosted_sites/naroo/program.htmlInternational audienceThe photographic observations in the Sternberg Astronomical Institute started in 1895. Observations were made with sept telescopes in Moscou and Crimea. In total, until 2004, almost 60 000 photographic plates have been accumulated. Most of them have been made to study variable stars and galaxies. Only the 9 000 from 60 000 photographic plates were made to determine the coordinates of Mars, Venus and selected asteroids. These photographic plates are processed. Some of obtained results are published. These 9 000 plates may be the subject of a new processing with the new star catalogs after they are scanned. This work can be undertaken if there is interest in new astrometric data with a modest accuracy for Mars, Venus, and selected asteroids. This year, work has begun to search for objects of the solar system in other 51 000 photographic plates made to study variable stars and galaxies. The main interest was in finding the planets with natural satellites. For given moments of exposure and the coordinates of the field center using a relevant software, we determine the presence of planets on each plate. A significant problem is that most of plates are identified only by the name of the galaxy or star. Our problem is also that only for 25 000 plates we have the moments and the coordinates recorded in the files. For the remaining 26 000 plates these data are still noted on paper. Of the 25 000 examined plates only on 340 of them the planets were found. We should also identify and write to file such data for 26,000 plates to search for planets with our software. For half of the 51 000 plates expected astrometric accuracy is of about 0.2 arcseconds and for other plates the accuracy is not better than 1 arcsecond of arc. About 1 700 photographic plates were scanned for photometric purposes. However astrometric accuracy of the scan does not match the possible accuracy of photographic plates
ESPriF: the Echelle Spectropolarimeter of the BTA Primary Focus. Correction of Low-Frequency Variations in the Star Image
The development of a corrector for low-frequency variations in the star image
at the input of ESPriF, the echelle spectropolarimeter of the BTA primary
focus, is reported. New technical solutions have made it possible to extend the
operating frequency range to 10Hz for stars brighter than 13^m.Comment: 9 pages, 2 figure

.The article will discuss the evolution of biography in ancient Mesopotamia and the relationship between biography and the cult calendar. The civilizations of the ancient East are divided into those where the biographies of people of a non-royal family are known (Egypt and China), and those where there are no biographies. The question arises as to why the literary genre of biography did not develop in ancient Mesopotamia. In the process of research, such genres of texts as royal inscriptions, annals, royal hymns, incantations, menologies, horoscopes of birth, death and activity are considered. It is shown that the genre of biography could not take shape in ancient Mesopotamia due to the constant projection of human actions onto natural phenomena or the appearance of celestial bodies, which deprived the individualβs behavior of free will and prevented the perception of his actions as independent.ΠΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΠ΅ Π²ΡΠΏΠΎΠ»Π½Π΅Π½ΠΎ ΠΏΡΠΈ ΠΏΠΎΠ΄Π΄Π΅ΡΠΆΠΊΠ΅ Π³ΡΠ°Π½ΡΠ° Π ΠΠ€ β 19-18-00085 Β«ΠΠ°Π»Π΅Π½Π΄Π°ΡΠ½ΡΠ΅ ΠΏΡΠ°Π·Π΄Π½ΠΈΠΊΠΈ Π΄ΡΠ΅Π²Π½Π΅Π³ΠΎ ΠΠΎΡΡΠΎΠΊΠ°: ΠΊΠ°Π»Π΅Π½Π΄Π°ΡΠ½ΡΠΉ ΡΠΈΡΡΠ°Π» ΠΈ ΡΠΎΠ»Ρ ΡΠ΅ΠΌΠΏΠΎΡΠ°Π»ΡΠ½ΡΡ

The Role of Pension Funds in Financing US Federal Debt
The article examines main trends in financing the federal debt, pointing out its structure, with focus on the role of pension funds as a source of financing; because the surplus of Social Security funds is loaned to the rest of the government; interlinks concerning this process and possible problems; the peculiarities of the federal government pension systemβs investment in the government bonds. The US public debt as a share of GDP is much less than in many countries, but its volume is near 20 trln. doll. It may be classified by marketable and non-marketable securities, which are mainly owed to certain government trust funds such as the Social Security trust fund. So the Social Security trust fund, in effect is exchanging one type of debt for the other, taking into consideration that the non-marketable securities represent amounts owed to the beneficiaries. The reserves are in effect borrowed for a time by the rest of the government, and then repaid with interest when the trust funds need them back. Looking ahead Social Security will continue to be financed through its own receipts, mainly payroll tax; and Social Security Trust Fund surplus will become diminishing, with less possibilities to finance federal debt
The Role of Pensioners in the American Electorate
The article examines fundamental demographic changes in the USA that have been shifting the electorate and as a result - American politics; with wide gaps between the generations on key social, economic, political issues. The US presidential elections since 1980 were dominated by baby boomers (born 1946-1964) and prior generations, who have cast the vast majority of votes in every presidential election. The 2016 electorate has been the most diverse in the US history due to strong growth of young generations, and especially among Hispanic eligible voters. Millennials (born 1981β1998) and X generation (born 1965-1980) surpassed Baby Boomers and more old generations whose choices differ significantly in many fields; but the key problem is who really votes. The age structure of the American electorate and its influence on the election results; the role of pensioners and those, whoβll retire in the nearest future, as voters at the federal and state levels are in focus
