  9. Electric vehicle almanac

    SciTech Connect

    Brewer, D.E.

    1995-12-31

    Electric Vehicle Almanac presents an overview of the current activity in electric vehicle development. Brief highlights are given for different types of vehicles--ranging from mini town cars to high tonnage industrial trucks--produced by 48 different EV developers around the world. Most of these vehicles are concept cars, prototypes and demonstration vehicles. However, a few are cars actually in modest-volume production in Europe. Extensively covered in the almanac are research and development activities for EV batteries. As widely attested, current battery state-of-the-art is--in terms of both energy storage capacity and instant power response--at least one order of magnitude shy of putting EVs in any sort of contention with internal combustion vehicles. Two sections are worth special mention. One is excerpted from an EV thermal management study by Arthur D. Little, a renowned consulting company. This study suggests that current technology exists to make EVs practical for cold weather driving, typical of the Northeastern US. The other highlights an examination by the US Environmental Protection Agency into the energy efficiencies and costs of EVs viz-a-viz internal combustion vehicles.

  15. Stars on Local Time: A Personal Almanac

    NASA Astrophysics Data System (ADS)

    Gottlieb-Roberts, M.

    2016-01-01

    First presented at INSAP VIII, the artwork A Personal Almanac is my interpretation of the familiar seasons-of-life allegory. The booklet's eight pairs of seasonal pages— spring equinox through the cross-quarter Groundhog Day—portray a life in the decades from the 1940s to the 2010s under the stars of rural Georgia, France, Miami, West Africa and the other places I have lived. A Personal Almanac is included in the art book A Durable Tale, the illustrated story of my thirty-year search in the Southeast United States and in West Africa for living memories of old star almanacs. In that odyssey I uncovered some very deep roots for an oral literature of the African desert, the nomadic bard's star story that I believe inspired creation of the first nine tablets of the standard version Babylonian Gilgamesh.

    NASA Astrophysics Data System (ADS)

    Han, In-Woo; Shin, Junho

    1994-12-01

    In Korea Astronomy Observatory, we developed a S/W package to compile the Korean Nautical Almanac. We describe the motivation to develop the S/W and explain the S/W package in general terms. In appendix, we describe the procedure to calculate the polaris table in more detail. When we developed the S/W, we paid much attention to produce accurate data. We also made great effort to automate the compilation of Nautical Almanac as far as possible, since the compilation is time consuming labour extensive. As a result, the S/W we developed turns out to be very accurate and efficient to compile Nautical Almanac. In fact, we could compile a Korean Nautical Almanac in a few days.

  5. Explanatory Supplement to the Astronomical Almanac (3rd Edition)

    NASA Astrophysics Data System (ADS)

    Urban, Sean E.; Seidelmann, P. K.

    2014-01-01

    Publications and software from the the Astronomical Applications Department of the US Naval Observatory (USNO) are used throughout the world, not only in the Department of Defense for safe navigation, but by many people including other navigators, astronomers, aerospace engineers, and geodesists. Products such as The Nautical Almanac, The Astronomical Almanac, and the Multiyear Interactive Computer Almanac (MICA) are regarded as international standards. To maintain credibility, it is imperative that the methodologies employed and the data used are well documented. "The Explanatory Supplement to the Astronomical Almanac" (hereafter, "The ES") is a major source of such documentation. It is a comprehensive reference book on positional astronomy, covering the theories and algorithms used to produce The Astronomical Almanac, an annual publication produced jointly by the Nautical Almanac Office of USNO and Her Majesty's Nautical Almanac Office (HMNAO). The first edition of The ES appeared in 1961, and the second followed in 1992. Several major changes have taken place in fundamental astronomy since the second edition was published. Advances in radio observations allowed the celestial reference frame to be tied to extragalactic radio sources, thus the International Celestial Reference System replaced the FK5 system. The success of ESA's Hipparcos satellite dramatically altered observational astrometry. Improvements in Earth orientation observations lead to new precession and nutation theories. Additionally, a new positional paradigm, no longer tied to the ecliptic and equinox, was accepted. Largely because of these changes, staff at USNO and HMNAO decided the time was right for the next edition of The ES. The third edition is now available; it is a complete revision of the 1992 book. Along with subjects covered in the previous two editions, the book also contains descriptions of the major advancements in positional astronomy over the last 20 years, some of which are

  6. The future of almanac services --- an HMNAO perspective

    NASA Astrophysics Data System (ADS)

    Bell, S.; Nelmes, S.; Prema, P.; Whittaker, J.

    2015-08-01

    This talk will explore the means for delivering almanac data currently under consideration by HM Nautical Almanac Office in the near to medium future. While there will be a need to continue printed almanacs, almanac data must be available in a variety of forms ranging from paper almanacs to traditional web services through to applications for mobile devices and smartphones. The supply of data using applications may call for a different philosophy in supplying ephemeris data, one that differentiates between an application that calls on a web server for its data and one that has built-in ephemerides. These ephemerides need to be of a reasonably high precision while maintaining a modest machine footprint. These services also need to provide a wide range of applications ranging from traditional sunrise/set data though to more specialized services such as celestial navigation. The work necessary to meet these goals involves efficient programming, intuitive user interfaces, compact and efficient ephemerides and a suitable range of tools to meet the user's needs.

  7. 150 Years of the American Nautical Almanac Office

    NASA Astrophysics Data System (ADS)

    Dick, S. J.

    1999-05-01

    In 1849, 50 years before the founding of the American Astronomical Society, the American Nautical Almanac Office was established in Cambridge, Massachusetts. Although the British had published a Nautical Almanac since 1767, both patriotic and practical reasons lay behind the founding of an American Nautical Almanac Office in the context of the growth of science in the United States. Lt. Charles Henry Davis served as the first Superintendent. In 1866 the Office moved to Washington, D. C., and beginning in 1893 it was physically located at the new (present) site of the U. S. Naval Observatory, of which it became a part over the next few years, and where it has since remained. >From its beginning the work of the Office was much broader than the publication of data for navigation. The Office also sought to improve the theories of motion of the Sun, Moon and planets, and the astronomical constants on which the Almanac was based. Under Simon Newcomb, Superintendent of the Office from 1877 until his retirement in 1897, a consistent system of constants was devised; some of these constants remained unchanged until 1984. The American Nautical Almanac Office was dominated before World War II by its Directors William S. Eichelberger (1910-1929) and A. James Robertson (1929-1939). During the War years Wallace J. Eckert introduced punched card techniques to the Office. Gerald Clemence used these techniques to improve planetary theories during his years as Director (1945-1958), and also ushered in the era of the electronic computer for both research and production. International collaboration was a hallmark of the tenures of Clemence, Edgar Woolard, Raynor Duncombe and P. K. Seidelmann, who also implemented changes necessitated by the Space Age. Since 1990 the Nautical Almanac Office has been part of the Astronomical Applications Department of the Naval Observatory.

  9. Astronomy and Geography vs. Navigation: Defining a Role for an American Nautical Almanac, 1844-1850

    NASA Astrophysics Data System (ADS)

    Waff, C.

    1997-12-01

    Between 1844 (when he was appointed the first superintendent of what would become the U.S. Naval Observatory) and 1848, Navy Lieutenant Matthew Fontaine Maury repeatedly advocated, both to the Navy Department and members of Congress, the production of an American Nautical Almanac. Maury apparently envisioned a nautical almanac, as its name implies, as being used solely by navigators, and he argued that American ships, both naval and maritime, should not have to rely on the almanacs produced by Great Britain and other European nations. In 1849, however, when an American Nautical Almanac was authorized by Congress, an anonymous writer (possibly Benjamin Apthorp Gould) and Navy Lieutenant Charles Henry Davis (the first superintendent of the Almanac office) pointed out that astronomers and geographers also made use of almanacs or astronomical ephemerides (as they are alternatively called), and they argued that, primarily for the benefit of such users, a new almanac/ephemeris more accurate than the European ones should be produced as a showcase of the skills and talents of the emerging American astronomical community. Whether the newly authorized Almanac should be produced for navigators or for astronomers and geographers was hotly debated in late 1849 and early 1850 after Davis proposed using, primarily for the benefit of the latter group, an American prime meridian as the basis for the Almanac's tables. This debate ultimately led to the Almanac, for many years, having separate sets of tables based on the Greenwich prime meridian (favored by navigators) and on a prime meridian passing through the Naval Observatory. Congress's endorsement of this compromise, which was coupled with a stated preference for an American prime meridian, was another decisive step (following the establishment of the Naval Observatory) in the federal government's promotion of the science of astronomy in the United States.

  10. The Liberating Role of Astronomy in an Old Farmer's Almanac: David Rittenhouse's "Useful Knowledge" and a Benjamin Banneker Almanac for 1792

    NASA Astrophysics Data System (ADS)

    Walker, Theodore, Jr.

    2012-06-01

    Traditionally, astronomy met theology and political ethics in almanacs. As presented in early New England almanacs of the farmer's type, astronomy was deity-affirming and liberty-oriented. The old English label for astronomy that affirms theology was "Astro-theology" (William Derham, 1715). The New England rendering of astro-theology was so strongly oriented towards liberty that it can now be labeled astro-liberation theology. This 21st century label is appropriate because 18th century New England printers and astronomers used astronomy to demonstrate the glory of the Creator (astro-theology) and to encourage liberation from colonialism and slavery (astro-liberation theology). A philosophy of astronomy as "useful knowledge' expressed by David Rittenhouse in 1775 - and implicit in a Benjamin Banneker almanac for 1792 - included liberty-oriented visions of planet Earth as seen from outer space, and liberty-oriented visions of intelligent life on other planets orbiting other stars.

  12. Ceque System of Cuzco: A Yearly Calendar-Almanac in Space and Time

    NASA Astrophysics Data System (ADS)

    Zuidema, R. Tom

    The Incas used for the administration of Cuzco, the capital of their empire, and its valley a system of 41 directions, called ceque, as viewed from their central temple of the Sun. This system registered their concerns with space, including ritual space, hierarchy, and time, the latter in the form of a detailed calendar-almanac of weekly, monthly, seasonal, and yearly activities. From Inca times are also preserved some textiles that represent different regular calendars concerning the sun, moon, and stars. Detailed ethnohistoric evidence allows the reconstruction of the Ceque calendar-almanac.

  13. Analysis of Time Data in Chinese Astronomical Almanacs of the Late 18th Century

    NASA Astrophysics Data System (ADS)

    Lee, K.-W.; Mihn, B.-H.; Ahn, Y. S.; Choi, G.-E.

    2012-09-01

    We investigated the time data in Chinese astronomical almanacs of the late 18th century in order to estimate the accuracy of the Shixian calendar. It is known that the calendar was enforced during the period of the Ching dynasty (1664--1912), and several astronomical almanacs using the calendar are preserved in the Kyujanggak Institute for Korean Studies of Korea; these almanacs cover the years 1772, 1773, 1774, 1780, 1781, 1783, 1785, and 1787. We compiled the times of the new moon, sunrise/sunset, and twenty-four seasonal subdivisions from the almanacs and compared them with the results of modern calculations. As a result, we found that the times of the new moon and twenty-four seasonal subdivisions show average differences of ˜ 3.35 ± 4.43 and ˜ 9.67± 13.24 min, respectively. Regarding he sunrise/sunset time, however, we found that the difference was less than 1 min when we defined the time as the moment that the zenith distance (z) of the Sun is 90°, unlike the modern definition, z=90° 50'. We expect that this study to contribute to the understanding of the accuracy obtained by Shixian calendar in calculations of the movements of celestial bodies.

  10. Study of the star catalogue (epoch AD 1396.0) recorded in ancient Korean astronomical almanac

    The study of old star catalogues provides important astrometric data. Most of the researches based on the old star catalogues were manuscript published in Europe and from Arabic/Islam. However, the old star catalogues published in East Asia did not get attention. Therefore, among the East Asian star catalogues we focus on a particular catalogue recorded in a Korean almanac. Its catalogue contains 277 stars that are positioned in a region within 10° of the ecliptic plane. The stars in the catalogue were identified using the modern Hipparcos catalogue. We identified 274 among 277 stars, which is a rate of 98.9 per cent. The catalogue records the epoch of the stars' positions as AD 1396.0. However, by using all of the identified stars we found that the initial epoch of the catalogue is AD 1363.1 ± 3.2. In conclusion, the star catalogue was compiled and edited from various older star catalogues. We assume a correlation with the Almagest by Ptolemaios. This study presents newly analysed results from the historically important astronomical data discovered in East Asia. Therefore, this star catalogue will become important data for comparison with the star catalogues published in Europe and from Arabic/Islam.

  5. Almanac 2013: cardiac arrhythmias and pacing.

    PubMed

    Liew, Reginald

    2013-10-01

    Important advances have been made in the past few years in the fields of clinical cardiac electrophysiology and pacing. Researchers and clinicians have a greater understanding of the pathophysiological mechanisms underlying atrial fibrillation (AF), which has transpired into improved methods of detection, risk stratification, and treatments. The introduction of novel oral anticoagulants has provided clinicians with alternative options in managing patients with AF at moderate to high thromboembolic risk and further data has been emerging on the use of catheter ablation for the treatment of symptomatic AF. Another area of intense research in the field of cardiac arrhythmias and pacing is in the use of cardiac resynchronisation therapy (CRT) for the treatment of patients with heart failure. Following the publication of major landmark randomised controlled trials reporting that CRT confers a survival advantage in patients with severe heart failure and improves symptoms, many subsequent studies have been performed to further refine the selection of patients for CRT and determine the clinical characteristics associated with a favourable response. The field of sudden cardiac death and implantable cardioverter defibrillators also continues to be actively researched, with important new epidemiological and clinical data emerging on improved methods for patient selection, risk stratification, and management. This review covers the major recent advances in these areas related to cardiac arrhythmias and pacing.

    Compaction of the eukaryotic genome into the confined space of the cell nucleus must occur faithfully throughout each cell cycle to retain gene expression fidelity. For decades, experimental limitations to study the structural organization of the interphase nucleus restricted our understanding of its contributions towards gene regulation and disease. However, within the past few years, our capability to visualize chromosomes in vivo with sophisticated fluorescence microscopy, and to characterize chromosomal regulatory environments via massively-parallel sequencing methodologies have drastically changed how we currently understand epigenetic gene control within the context of three-dimensional nuclear structure. The rapid rate at which information on nuclear structure is unfolding brings challenges to compare and contrast recent observations with historic findings. In this review, we discuss experimental breakthroughs that have influenced how we understand and explore the dynamic structure and function of the nucleus, and how we can incorporate historical perspectives with insights acquired from the ever-evolving advances in molecular biology and pathology.

  20. Almanac 2011: acute coronary syndromes. The national society journals present selected research that has driven recent advances in clinical cardiology.

    Knight, Charles J; Timmis, Adam D

    2011-12-01

    This overview highlights some recent advances in the epidemiology, diagnosis, risk stratification and treatment of acute coronary syndromes. The sheer volume of new studies reflects the robust state of global cardiovascular research but the focus here is on findings that are of most interest to the practising cardiologist. Incidence and mortality rates for myocardial infarction are in decline, probably owing to a combination of lifestyle changes, particularly smoking cessation, and improved pharmacological and interventional treatment. Troponins remain central for diagnosis and new high-sensitivity assays are further lowering detection thresholds and improving outcomes. The incremental diagnostic value of other circulating biomarkers remains unclear and for risk stratification simple clinical algorithms such as the GRACE score have proved more useful. Primary PCI with minimal treatment delay is the most effective reperfusion strategy in ST elevation myocardial infarction (STEMI). Radial access is associated with less bleeding than with the femoral approach, but outcomes appear similar. Manual thrombectomy limits distal embolisation and infarct size while drug-eluting stents reduce the need for further revascularisation procedures. Non-culprit disease is best dealt with electively as a staged procedure after primary PCI has been completed. The development of antithrombotic and antiplatelet regimens for primary PCI continues to evolve, with new indications for fondaparinux and bivalirudin as well as small-molecule glycoprotein (GP)IIb/IIIa inhibitors. If timely primary PCI is unavailable, fibrinolytic treatment remains an option but a strategy of early angiographic assessment is recommended for all patients. Non-ST segment elevation myocardial infarction(NSTEMI) is now the dominant phenotype and out-comes after the acute phase are significantly worse than for STEMI. Many patients with NSTEMI remain undertreated and there is a large body of recent work seeking to define the most effective antithrombotic and antiplatelet regimens for this group of patients.The benefits of early invasive treatment for most patients are not in dispute but optimal timing remains unresolved. Cardiac rehabilitation is recommended for all patients with acute myocardial infarction but take-up rates are disappointing. Home-based programmes are effective and may be more acceptable for many patients. Evidence for the benefits of lifestyle modification and pharmacotherapy for secondary prevention continues to accumulate but the argument for omega-3 fatty acid supplements is now hard to sustain following recent negative trials. Implantable cardioverter defibrillators for patients with severe myocardial infarction protect against sudden death but for pri-mary prevention should be based on left ventricular ejection fraction measurements late (around 40 days)after presentation, earlier deployment showing no mortality benefit.

    Important advances have been made in the past few years in the fields of clinical cardiac electrophysiology and pacing. Researchers and clinicians have a greater understanding of the pathophysiological mechanisms underlying atrial fibrillation (AF), which has transpired into improved methods of detection, risk stratification, and treatments. The introduction of novel oral anticoagulants has provided clinicians with alternative options in managing patients with AF at moderate to high thromboembolic risk and further data has been emerging on the use of catheter ablation for the treatment of symptomatic AF. Another area of intense research in the field of cardiac arrhythmias and pacing is in the use of cardiac resynchronisation therapy (CRT) for the treatment of patients with heart failure. Following the publication of major landmark randomised controlled trials reporting that CRT confers a survival advantage in patients with severe heart failure and improves symptoms, many subsequent studies have been performed to further refine the selection of patients for CRT and determine the clinical characteristics associated with a favourable response. The field of sudden cardiac death and implantable cardioverter defibrillators also continues to be actively researched, with important new epidemiological and clinical data emerging on improved methods for patient selection, risk stratification, and management.This review covers the major recent advances in these areas related to cardiac arrhythmias and pacing.

    The appareant coordinates in the printed material almanacs have inconsistencies concerning the reference frame. These inconsistencies produce secular errors of about 0.001 arcsec/century in the equatorial coordinates and periodic errors of about 0.04 arcsec in the ecliptic coordinates. It is recommended that the calculation of apparent places of planets should be based on a consistent reference frame as well as on a consistent system of astronomical constants.

    Schilling, K.E.; Kiniry, J.R.

    2007-01-01

    Reed canarygrass (Phalaris arundinacea) commonly invades meadow wetlands, effectively dominating water use and outcompeting native plants. Objectives of this study were to (i) estimate daily, seasonal and annual water use by reed canarygrass using shallow water table fluctuations; and (ii) calibrate the ALMANAC (Agricultural Land Management Alternative with Numerical Assessment Criteria) model to accurately simulate water uptake by this grass. Using a groundwater well, the water table under an area in Iowa dominated by reed canarygrass was monitored hourly. Differences between water level measurements taken each hour were averaged to determine the hourly water table change in each month. Using these estimates of water use, the ALMANAC model was then calibrated to simulate plant transpiration values close to these water table use rates. Average monthly calculated daily plant water use rates were 3.3 mm d-1 in July and 2.3-2.8 mm d-1 in May, June, August, and September. Simulated bimonthly values for measured water use and plant transpiration simulated by the ALMANAC model differed by 14% or less. From May to October the mean ratio of measured to simulated values was 94%. Thus, the similarity between simulated plant transpiration and water use from the water table showed promise that this process-based model can realistically simulate water use under such grassland systems. ?? 2007 Elsevier B.V.

Hell's scientific merits won him the membership in several European Academies, and his name is found on the lunar maps.

  18. Influence of Ephemeris Error on GPS Single Point Positioning Accuracy

    NASA Astrophysics Data System (ADS)

    Lihua, Ma; Wang, Meng

    2013-09-01

    The Global Positioning System (GPS) user makes use of the navigation message transmitted from GPS satellites to achieve its location. Because the receiver uses the satellite's location in position calculations, an ephemeris error, a difference between the expected and actual orbital position of a GPS satellite, reduces user accuracy. The influence extent is decided by the precision of broadcast ephemeris from the control station upload. Simulation analysis with the Yuma almanac show that maximum positioning error exists in the case where the ephemeris error is along the line-of-sight (LOS) direction. Meanwhile, the error is dependent on the relationship between the observer and spatial constellation at some time period.

  19. Chinese Calendar and Mathematical Astronomy

    NASA Astrophysics Data System (ADS)

    Sun, Xiaochun

    The Chinese calendar (li 历) was a system of mathematical astronomy that included mathematical techniques for the computation of celestial movements. It was the basis for producing astronomical ephemerides and annual almanacs. Calendar making started early in China. Since the Great Inception calendar reform in 104 BC, China has produced about 100 calendars (astronomical systems). The focus of calendar making was the prediction of solar, lunar, and planetary motions. As astronomy developed, new observational discoveries were incorporated into the calendar to make the system more precise. The history of astronomy in ancient China was largely a history of calendar making.

    This report outlines the algorithms developed at the Colorado Center for Astrodynamics Research to model yaw and predict the axial ratio as measured from a ground station. The algorithms are implemented in a collection of Matlab functions and scripts that read certain user input, such as ground station coordinates, the UTC time, and the desired GPS (Global Positioning System) satellites, and compute the above-mentioned parameters. The position information for the GPS satellites is obtained from Yuma almanac files corresponding to the prescribed date. The results are displayed graphically through time histories and azimuth-elevation plots.

    This paper contains a collection of computational algorithms for determining geocentric ephemerides of Earth satellites, useful for both mission planning and data reduction applications. Special emphasis is placed on the computation of sidereal time, and on the determination of the geocentric coordinate of the center of the Sun, all to the accuracy found in the Astronomical Almanac. The report is completely self-contained in that no requirement is placed on any external source of information, and hence, these methods are ideal for computer application.

    Astronomical data making such as forming a calendar, period of day, determining the time of rising/setting of the sun and the onset of twilight are essential in our daily lives. Knowing the calendar day of the past is particularly crucial for studying the history of a clan or a nation. To verify previous studies in the calendar day of the Joseon dynasty (1392 -- 1910), we investigate the sexagenary cycle of the new moon day (i.e., the first day in a lunar month) by using sources such as results of the calculations using the Datong calendar (a Chinese Calendar of the Ming Dynasty) and the data of Baekjungryeok (a Perpetual Calendar; literally, a one hundred-year almanac). Compared with the study of Ahn et al., we find that as many as 17 sexagenary cycles show discrepancies. In the cases of nine discrepancies, we find that the sexagenary cycles of this study are identical to those of the almanacs at that time. In addition, we study five sexagenary cycles by using the historical accounts of Joseon Wangjo Sillok (Annals of the Joseon Dynasty), Seungjeongwon Ilgi (Daily Reports of Royal Secretariat), Chungung Ilgi (Logs of Crown Prince), and so forth. For the remaining discrepancies, we present historical literature supporting the results of this study. This study will greatly contribute to the identification of the lunisolar calendar days during the Joseon dynasty as the dates of the modern (i.e., Gregorian) calendar.

  5. Colonial American Astronomy

    While a foundation of German scientific methods enabled the rapid growth of North American Astronomy in the nineteenth century, during the seventeenth and most of the eighteenth centuries, the colonial men of science looked only to the English mother country for scientific patronage and guidance. An essay on fundamental astronomy appeared in one of the annual colonial almanacs as early as 1656, telescopic observations were made about 1660 and the first original colonial astronomical work was published by Thomas Danforth on the comet of 1664. By 1671 the Copernican ideas were so espoused at Harvard College that a physics class refused to read a Ptolemaic textbook when it was assigned to them by a senior instructor. At least in the Cambridge-Boston area, contemporary colonialist had access to the most recent scientific publications from the mother country. Observations of the great comet of 1680 by the Almanac maker, John Foster, reached Isaac Newton and were used and gratefully acknowledged in his Principia. During the seventeenth century the colonial interest in astronomy was more intense than it was for other sciences but colonists still occupied a position in the scientific backwater when compared with contemporary European scientists. Nevertheless, the science of astronomy was successfully transplanted from England to North America in the seventeenth century.

    librations of the moon was adopted by The Astronomical Almanac. This improved the method of calculating selenographic coordinates. The selenographic coordinates computed by SUNTRACKER are identical to the pre-1981 Astronomical Almanac values. A comparison between the program's values and the 1993 Astronomical Almanac's values found the maximum deviations in longitude and latitude to be .030 deg. and .034 deg. respectively. The average deviations were .013 deg. in selenographic co-longitude and .017 deg. in selenographic latitude. SUNTRACKER is written in FORTRAN 77 for IBM PC compatible computers running MS-DOS. The sample executable included on the media requires 64K of RAM and the Lahey FORTRAN 77 run time library for execution. The standard distribution medium for this program is a 5.25 inch 360K MS-DOS format diskette.

  7. Increased induced abortion rate in 1966, an aspect of a Japanese folk superstition.

    1975-04-01

    Adecrease of about 463 000 live births occurred in Japan in 1966, constituting a sharp departure from the linear trend before and after. This was partly caused by contraception and partly by induced abortion. The induced abortion rate, 43.1 per 1000 births in the year (a total of 65 000), was significantly higher than the 30.6 expected (46.200 total) from the regression trend computed from the years 1963 to 1969. No epidemics were reported in 1966 which might have caused the increase in abortion. It is more likely to be due to observance of Hinoe-Uma (Elder Fire-Horse), which comes round every sixty years by zodiac almanac. This event represents a superstition observed only by the Japanese, in whcih it is a bad omen for female babies to be born in the year. 1966 was the most recent year of Hinoe-Uma.

    With the cost of consuming resources increasing (both economically and ecologically), homeowners need to find ways to curb consumption. The Almanac of Minutely Power dataset Version 2 (AMPds2) has been released to help computational sustainability researchers, power and energy engineers, building scientists and technologists, utility companies, and eco-feedback researchers test their models, systems, algorithms, or prototypes on real house data. In the vast majority of cases, real-world datasets lead to more accurate models and algorithms. AMPds2 is the first dataset to capture all three main types of consumption (electricity, water, and natural gas) over a long period of time (2 years) and provide 11 measurement characteristics for electricity. No other such datasets from Canada exist. Each meter has 730 days of captured data. We also include environmental and utility billing data for cost analysis. AMPds2 data has been pre-cleaned to provide for consistent and comparable accuracy results amongst different researchers and machine learning algorithms.

    The 260 day Mesoamerican ``Sacred Almanac", or sacred calendar, indirectly contains all the solar system information embodied within the law first proposed by Bode in 1772. However, the sacred 260 day calendar of Mesoamerica is more accurate on average, and over two millennia older (Milbrath 1999). Furthermore, it will be shown that the Mesoamerican 260 day calendar is one of the most efficient calendars that can be constructed for tracking planetary motions, but only when the planet Mercury is included in the planet set. This suggests that the calendar's design was intentional, and that Mercury was known to ancient new world astronomers. The number of observational experiments needed to establish the 260 day calendar has also been estimated. In fact, the information burden is substantial, and it is tempting to suggest that the need for astronomical recordkeeping may have given rise to the development of writing in the new world.

    2014-12-01

    The adoption of IAU 2006 precession theory (Capitaine et al. 2003) introduced some small changes in IAU 2000A nutation theory, relevant at the mircroarcsecond level. These adjustments were derived in Capitaine et al. (2005) and are currently considered in international standards like, for example, IERS Conventions (2010) or in the Explanatory Supplement to the Astronomical Almanac (2013). We reexamine the issue, working out the induced modifications due to a change in the value of the obliquity of the ecliptic and to the secular variation of the Earth dynamical flattening. In particular, within the framework of the Hamiltonian theory of the rotation of the Earth we derive analytical expressions of those changes for the motion of the figure axis. These expressions and their corresponding numerical contributions will be compared with those obtained in Capitaine et al. (2005).

    In 1986, during the first year of graduate school, the lead author was sampling the water from a pitcher pump in front of “The Shack,” the setting of the opening essays in Aldo Leopold's renowned book A Sand County Almanac. The sampling was part of my Master's work that included quarterly monitoring of water quality on the Leopold Memorial Reserve (LMR) near Baraboo, Wisconsin. The Shack was already a well-known landmark, and it was common to come upon visitors and hikers there. As such, I took no special note of the man who approached me as I was filling sample bottles and asked, as was typical, “What are you doing?”

    This is a qualitative, descriptive and exploratory research, aiming to describe the set of ideas and knowledge that guide the use of complementary and integrative health practices (CIHP) by nurses, and analyze the challenges facing the applicability of these therapies by nurses in the hospital setting. The subjects were nurses in public hospital institutions of Rio de Janeiro. Data collection was done through semi-structured interviews and a technique of creativity and sensibility called Almanac. The results showed that the hegemony of the biomedical model in the formation and performance of health professionals hinders implementation of CIHP in hospital. However, as this model does not account for the complexity of the human being emerges the possibility of sharing with CIHP in care aiming, therefore, at comprehensiveness of the human being.

    The WATTS' charts provide the elevation of the limb of the moon using 1800 contour maps (step of 0.2deg) that cover all libration ranges of the moon. The contours of the maps were digitised by H.M. Nautical Almanac Office in the late 1960's, and then converted to a grid format by US Naval Observatory in the early 1970's. These charts are present in 2 forms: as an ascii file watts.dat (without carriage-return or line-feed!), or as a 3-D FITS file watts.fit (transformed from the ascii files with the program "make_fit.c"). More details, especially about the transformations between the original charts and the files stored here, and the special processing of the 36.0{deg} map (map#181), can be found in the "doc.txt" file.

    Hoskin, Michael

    Expertly written and lavishly illustrated, The Cambridge Illustrated History of Astronomy offers a unique account of astronomical theory and practice from antiquity to the present day. How did Moslems of the Middle Ages use astronomy to calculate the direction of Mecca from far-flung corners of the Islamic world? Who was the only ancient Greek to suspect that the earth might revolve around the sun? How did Christopher Columbus abuse his knowledge of a lunar eclipse predicted by an astronomical almanac? Packed with anecdotes and intriguing detail, this book describes how we observed the sky and interpreted what we saw at different periods of history; how this influenced our beliefs and mythology; and how great astronomers contributed to what we now know. The result is a lively and highly visual history of astronomy - a compelling read for specialists and non-specialists alike.

  20. Spatial forecasting of switchgrass productivity under current and future climate change scenarios.

    Evaluating the potential of alternative energy crops across large geographic regions, as well as over time, is a necessary component to determining if biofuel production is feasible and sustainable in the face of growing production demands and climatic change. Switchgrass (Panicum virgatum L.), a native perennial herbaceous grass, is a promising candidate for cellulosic feedstock production. In this study, current and future (from 2080 to 2090) productivity is estimated across the central and eastern United States using ALMANAC, a mechanistic model that simulates plant growth over time. The ALMANAC model was parameterized for representative ecotypes of switchgrass. Our results indicate substantial variation in switchgrass productivity both within regions and over time. States along the Gulf Coast, southern Atlantic Coast, and in the East North Central Midwest have the highest current biomass potential. However, these areas also contain critical wetland habitat necessary for the maintenance of biodiversity and agricultural lands necessary for food production. The southern United States is predicted to have the largest decrease in future biomass production. The Great Plains are expected to experience large increases in productivity by 2080-2090 due to climate change. In general, regions where future temperature and precipitation are predicted to increase are also where larger future biomass production is expected. In contrast, regions that show a future decrease in precipitation are associated with smaller future biomass production. Switchgrass appears to be a promising biofuel crop for the central and eastern United States, with local biomass predicted to be high (>10 Mg/ha) for approximately 50% of the area studied for each climate scenario. In order to minimize land conversion and loss of biodiversity, areas that currently have and maintain high productivity under climate change should be targeted for their long-term growth potential.

Direct knowledge sharing with farmers was done through (i) the implementation of five development projects, (ii) the organisation of so-called Farmers' Days (a dozen in total) in which research findings were demonstrated in the field, and (iii) the development of three extension manuals (two in the local Tigrigna language and one in English). In a bid to better reach the rural community, to hand the knowledge directly to the farmers, and hence to empower them, we took inspiration from 'almanacs' as they had been used in northwest Europe. One of the traditional functions of such almanacs is, in view of the close links between a calendar and farm works, to make them most useful to the peasant majority of the population. Hence, the objectives of the research reported here were to (1) develop a booklet in local Tigrigna language that holds basic research findings as well as local knowledge on land conservation, expressed in simple words in Tigrigna language, and combined with other useful and sometimes lighter information; (2) distribute it among farmers in our main research district with the aim that it is not only read by farmers but also passed on and discussed within the communities (farmer-to-farmer extension); and (3) evaluate the take-up of the messages contained in the booklet.

  2. Daytime Celestial Navigation for the Novice

    What kinds of astronomical lab activities can high school and college astronomy students carry out easily in daytime? The most impressive is the determination of latitude and longitude from observations of the Sun. The ``shooting of a noon sight'' and its ``reduction to a position'' grew to become a daily practice at the start of the 19th century1 following the perfection of the marine chronometer by John Harrison and its mass production.2 This technique is still practiced by navigators in this age of GPS. Indeed, the U.S. Coast Guard exams for ocean-going licenses include celestial navigation.3 These techniques continue to be used by the military and by private sailors as a backup to all-too-fallible and jammable electronic navigation systems. A sextant, a nautical almanac,4 special sight reduction tables,5 and involved calculations are needed to determine position to the nearest mile using the Sun, Moon, stars, or planets. Yet, finding latitude and longitude to better than 30 miles from measurements of the Sun's altitude is easily within the capability of those taking astronomy or physics for the first time by applying certain basic principles. Moreover, it shows a practical application of astronomy in use the world over. The streamlined method described here takes advantage of the similar level of accuracy of its three components: 1.Observations using a homemade quadrant6 (instead of a sextant), 2. Student-made graphs of the altitude of the Sun over a day7 (replacing lengthy calculation using sight reduction tables), and 3. An averaged 20-year analemma used to find the Sun's navigational coordinates8,9 (rather than the 300+ page Nautical Almanac updated yearly).

    Dr. Alan Dale Fiala, astronomer and expert on solar eclipses, died on May 26, 2010 in Arlington, Virginia, of respiratory failure after a brief illness. He was 67. Fiala had been a staff astronomer at the U.S. Naval Observatory in Washington, D.C., for his entire professional career, where he rose from a position as a summer intern to become the Chief of the Nautical Almanac Office, responsible for annual publications for astronomy and navigation that are used the world over. He retired from the observatory in 2000. Although a childhood case of polio affected his mobility for the rest of his life, he seldom let his physical constraints limit his activities, which were many and varied. Alan Fiala was born in Beatrice, Nebraska on November 9, 1942, the middle son of Emil A. ("John") and Lora Marie Fiala. Fiala's father was a postal clerk and Civil Service examiner. Fiala expressed interest in astronomy at a very young age. He contracted polio when he was 9. He graduated from Beatrice High School in 1960 with a straight-A average and went on to study at Carleton College. He received his B.A. summa cum laude after three years, in 1963, with a major in astronomy and minors in physics and mathematics. He was elected to Phi Beta Kappa, Sigma Xi, and Pi Mu Epsilon (mathematics). In 1962, Alan Fiala obtained a job as a summer intern at the Naval Observatory in Washington, working in the Nautical Almanac Office (NAO). He entered the graduate program at Yale University and continued to work summers at the observatory. He received his Ph.D. in 1968, under Gerald Clemence. His dissertation was titled "Determination of the Mass of Jupiter from a Study of the Motion of 57 Mnemosyne." After receiving his doctorate, Fiala became a permanent member of the Naval Observatory staff. Computers were just being introduced there and he participated in the automation of many procedures used to prepare the annual publications of the Nautical Almanac Office. One of his first assignments was

    On 21 August 2017, “…as the last ray of sunlight vanishes, a scene of unexampled beauty, grandeur, and impressiveness…” (Newcomb 1890) will break upon fortunate observers along a narrow band, approximately 73 mi (118 km) wide, that crosses twelve states from Oregon to South Carolina. In response to growing interest in the first total solar eclipse to sweep the continental United States in nearly a century, the U.S. Naval Observatory has developed an on-line resource center with direct links to 2017-specific services: the 2017 August 21 Total Solar Eclipse page (http://aa.usno.navy.mil/data/docs/Eclipse2017.php). The Solar Eclipse Computer (http://aa.usno.navy.mil/data/docs/SolarEclipses.php) calculates tables of local circumstances for events visible throughout the world. A similar service is available for lunar eclipses, Lunar Eclipse Computer (http://aa.usno.navy.mil/data/docs/LunarEclipse.php). The USNO Eclipse Portal (http://astro.ukho.gov.uk/eclbin/query_usno.cgi) provides diagrams and animations showing the global circumstances for events visible throughout the world and local circumstances for events visible at selected locations. The Web site, which includes both solar and lunar eclipses, is a joint effort with Her Majesty’s Nautical Almanac Office. The Eclipses of the Sun and Moon page (http://aa.usno.navy.mil/data/docs/UpcomingEclipses.php) links to electronic copies of the visibility maps from The Astronomical Almanac. The Eclipse Reference List (http://aa.usno.navy.mil/faq/docs/eclipse_ref.php) is a representative survey of the available literature for those interested in delving into these phenomena, either technically or historically. Less than 7 years after the 2017 total solar eclipse, another such spectacular event will cross a different swath of the continent on April 8, 2024. The U.S. Naval Observatory is planning a resource center for that event as well. If your plans for 2017 are not yet made, visit the 2017 August 21 Total Solar

    2014-01-01

    More and more Global Navigation Satellite Systems (GNSSs) have been developed and are in operation. Before integrating information on various GNSSs, the differences between the various systems must be studied first. This research focuses on analyzing the navigation data differences between the Chinese BeiDou Navigation Satellite System (BDS) and the United States' Global Positioning System (GPS). In addition to explaining the impact caused by these two different coordinate and time systems, this research uses an actual open service signal in space (SIS) for both GPS and BDS to analyze their current system performance. Five data quality analysis (DQA) mechanisms are proposed in this research to validate both systems' SIS navigation data. These five DQAs evaluate the differences in ephemeris and almanac messages from both systems for stability and accuracy. After all of the DQAs, the different issues related to GPS and BDS satellite information are presented. Finally, based on these DQA results, this research provides suggested resolutions for the combined use of GPS and BDS for navigation and guidance. PMID:25195848

    The activities on the outreach issues in the National Astronomical Observatory of Japan (NAOJ) are mainly conducted by the Public Relations Center established in June 1998. Its mission is to present the latest findings in astronomy to the public in a manner that is understandable, contemporary, and exciting. For this purpose, we provide a wide range of services and deliver a variety of scientific information through multiple ways. We also maintain an effective partnership with lots of dissemination experts working at the public observatories, the science museums, and the planetariums in Japan. The representative outreach activities in NAOJ are follows. • Telephone service to answer the questions on astronomy (about 10,000 calls a year) • Press release (about 60 a year) to about 100 registered journalists • Press Members' Lounge" for registered journalists • A special seminar for science journalists every year • Service of astronomical ephemeredes, and nautical almanacs. • Weekly news letter service named "Astro-Topics" • Monthly paper magazine "NAOJ news" • Web site service (http://www.nao.ac.jp/) (about 10^7 hits a year) • Open campus or visitor service to the public • Regular star party using a modern 50-cm reflector twice a month • Coordination and cooperation with other astronomical facilities.

    The information in this booklet was compiled to answer inquiries received by the U.S. Geological Survey from students; teachers; writers; editors; publishers of encyclopedias, almanacs, and other reference books; and people in many other fields of work. The elevations of features and distances between points in the United States were determined from surveys and topographic maps of the U.S. Geological Survey or obtained from other sources. In most cases, the elevations were determined from surveys and from 1:24,000- and 1:25,000-scale, 7.5-minute topographic quadrangle maps. In Alaska, information was taken from 1:63,360-scale, 15-minute topographic quadrangle maps. In a few cases, data were obtained from older, 1:62,500-scale, 15-minute maps; these maps are being replaced with larger-scale 7.5-minute coverage.

    With the cost of consuming resources increasing (both economically and ecologically), homeowners need to find ways to curb consumption. The Almanac of Minutely Power dataset Version 2 (AMPds2) has been released to help computational sustainability researchers, power and energy engineers, building scientists and technologists, utility companies, and eco-feedback researchers test their models, systems, algorithms, or prototypes on real house data. In the vast majority of cases, real-world datasets lead to more accurate models and algorithms. AMPds2 is the first dataset to capture all three main types of consumption (electricity, water, and natural gas) over a long period of time (2 years) and provide 11 measurement characteristics for electricity. No other such datasets from Canada exist. Each meter has 730 days of captured data. We also include environmental and utility billing data for cost analysis. AMPds2 data has been pre-cleaned to provide for consistent and comparable accuracy results amongst different researchers and machine learning algorithms. PMID:27271937

    It is a continuing policy of the Nautical Almanac Office to prepare issues of the series of Naval Observatory Circulars containing detailed information for observing most total solar eclipses and some annular solar eclipses. This is a service to the international scientific community, based on agreements with Commissions and Working Groups of the International Astronomical Union. A total eclipse of the Sun will occur on Thursday, 17 March and Friday, 18 March 1988. It will be preceded by an associated short partial eclipse of the Moon on 3 March. The duration of totality of the solar eclipse will approach 4 minutes at maximum, the longest since 11 June 1983. Not much of the path is over land. First landfall will occur just after sunrise at the west coast of Sumatra, at Oh 28m U.T. The track will cross Sumatra in three minutes, with the umbral shadow growing so as to increase both the width of the path and the duration of totality. Palembang lies near the central line, and is probably one of the most accessible such places. Bangka Island, just off the east coast of Sumatra, is relatively flat and a mining area. The path will reach Borneo at Oh 36m U.T. with the umbral shadow continuing to expand. It will take approximately 13 minutes to cross the island, and the track will lie completely within Indonesian territory on Borneo. The other major land mass in the path of totality is the southern tip of Mindanao.

    According to IAU 2000 resolutions, a reform of IAA RAS publications has been carried out during 2003-2006. In "The Astronomical Yearbook for 2007" the ephemerides of the Sun, the Moon and major planets are based on EPM 2004 theory developed in IAA RAS with accuracy adequate to DE405/LE405. Apparent places of stars are given in FK6/HIPPARCOS system referred to ICRS, and are calculated taking into account the new IAU 2000 model of nutation and the new IERS 2003 precession model which is practically close to P03 model. The sidereal time was determined by the Earth rotation angle. Coordinates of pole X, Y, CIO locator s and the equation of the origins are also presented. Matrixes of conversions from ICRS to the true equator and the equinox of date, as well as to the celestial intermediate origin and the true equator date are given. Navigating ephemerides are issued as "The Nautical Astronomical Yearbook" and "The Nautical Astronomical Almanac" biennial on the basis of DE405/LE405, new precession-nutation model, FK6/HIPPARCOS catalogues and the classical concept of the equinox. Nevertheless, the implementation of the new CIO concept in navigating ephemerides tables cannot be planned yet. At IAA RAS, the electronic versions of astronomical yearbooks have been developed allowing to calculate topocentric ephemerides. All the calculations are made with a specialized ERA programming system created in IAA RAS using the problem-oriented programming language for the solution of problems of ephemeris and dynamic astronomy.

    It has been generally known that Datong-li (a Chinese calendar in the Ming dynasty)was first introduced into Korea in the nineteenth reign of King Gongmin (1370) of the Goryeo dynasty and lasted to the third reign of King Hyeojong (1652) of the Joseon dynasty. This understanding is based on the records of Goryeo-sa (History of the Goryeo dynasty) and of Seoungwan-ji (Official book of Seoungwan)/ Jeungbomunheon bigo (Explanatory Notes of Library ocument). To verify the period of the use of Datong-li in Korea, we develop a Fortran code to calculate the calendar day by Datong-li and also investigate historical literatures and extant almanacs. As a result, we find the possibility that Datong-li had been in use since 1389 at least. However,we cannot confirm whether Datong-li was first enforced in 1370 or not. On the other hand, we confirm that Datong-li was used until 1653 and reintroduced during the period from 1667 to 1669. Also, we find that previous studies had some errors in the sexagenary cycle of the real first day of a month. We think that this study will contribute to understanding the calendrical history of the Joseon dynasty.

    At the age of 42, Franklin retired from his prosperous printing business, ``to have leisure to read, study, and make experiments." The scope of his scientific work was remarkable. Beyond his key contributions to understanding electrcity, Franklin wrote major papers on population growth, on meterology, on heat conduction and evaporation, charted the Gulf Stream, studied bioluminescence and the stilling of water waves by a surface layer of oil. He also advanced arguments in favor of conservation of mass and the wave theory of light. Although always alert for practical applications, his style was that of an explorer, eager for adventure and insight. However, Franklin did not consider science as important as public service. He promoted many civic projects in Philadelphia, including a circulating library, fire department, paving of streets, hospital, and was the prime mover in founding the American Philosophical Society and an academy that evolved into the University of Pennsylvania. As well as publishing the most widely read newspaper in the colonies and his bestselling almanac, he became public printer for several of the colonies and postmaster. He lived in England 14 years as a trade representative, largely struggling in vain. At the age of 70, he undertook a decade of service as minister to France, achieving against great odds crucial diplomatic triumphs.

The new IAU2006/2000 precession - nutation models, and the FK6/HIPPARCOS stellar catalogues were used in these editions. Ephemeris editions are based on the domestic EPM2004 (IAA RAS) theory of movement of planets, Sun and Moon. The electronic versions are developed for two editions. The important stage of work is creation of “The Personal Astronomical Yearbook ”’ (PersAY). The system gives ample opportunities to the user to put and to solve tasks of calculation of ephemerides for any moment in various time scales, and for any location of the observer on a terrestrial surface. Also in PersAY it is possible to calculate by means of DE405/LE405 theory to make comparison with others ephemeris editions. The time interval of validity of the system makes 2010 - 2015. Besides system of the removed access the "Navigator" was developed. It intended to solve some the navigating tasks describe d in NAA - 2. The system is accessible on a site http://shturman.ipa.nw.ru/ (in Russian). In electronic systems as in Y the same reduce theories and the theory of movement of planets, the Sun, the Moon are used. All calculations are work out on the basis of the multifunctional software system ERA.

    2000-11-01

    The Great Patent Medicine Era (1865-1907) was the golden age of secret remedies--quack, non-prescription medicinal products, sold over-the-counter. Making outrageous and unsubstantiated claims, the makers of dental nostrums purported to effectively treat stained teeth, bad breath, diseased gums, toothache and teething discomfort. No proof was required to substantiate the safety and effectiveness of these concoctions. Advertisements for patent medicines were widespread, appearing in newspapers, almanacs, magazines, trade cards and multiple other media forms. Many dental patent medicines contained acids, abrasive substances, alcohol and/or narcotics, such as heroin, cocaine and morphine. Sozodont Tooth Powder, the most widely promoted and successful dentifrice of this era, claimed to "harden and invigorate the gums, purify and perfume the breath and beautify and preserve the teeth from youth to old age." Early dental researchers found that this remedy contained harsh ingredients (such as acid, sharp abrasives and astringents) which could destroy tooth substance. Mrs. Winslow's Soothing Syrup, an extremely popular dental nostrum, was intended to quiet a fretful child during the teething process. However, it contained generous levels of alcohol and morphine sulfate which could cause coma, addiction or death in an infant. Although somewhat chemically altered, these two products were eventually removed from the market in the 1930s.

    2007-12-01

    In 2007 the Astronomical Society of the Pacific awarded the 100th Catherine Wolfe Bruce gold medal for lifetime contributions to astronomy. The first medalist, Simon Newcomb in 1898, was a celestial mechanician who supervised the computations of orbits and compilation of almanacs, while the second, Arthur Auwers in 1899, observed visually and compiled catalogs of stellar positions and motions. In contrast the last two medalists, Martin Harwit in 2007 and Frank Low in 2006, are pioneers of infrared astronomy from airplanes and satellites. In between have come theoretical and experimental physicists, mathematicians, and radio astronomers, but the majority of medalists have been optical observers, celestial mechanicians (in the early years) and theoretical astrophysicists. Although astronomers are usually honored with the medal twenty to sixty years after their best work is done, we are starting to see more practitioners of the new astronomies, but to date there have been few representatives of the large teams that now dominate astronomical research. I will present an overview of the medalists and how their fields, styles and demographic characteristics have changed.

    During the whole period of the Second World War, England and the USA have exchanged astronomical ephemerides with Germany, even though these data were used for the navigation of warships and aircraft and were therefore of war importance. This astonishing fact is attested by numerous documents which survived in the archives of the Astronomisches Rechen-Institut (ARI). In Germany, the exchange was even explicitly authorized by the ministry which supervised the ARI (i.e. the Reichserziehungsminister). We present here examples of ephemerides for the Sun, the Moon, planets and stars, and explain the position determination by means of astronomical data. Ephemerides were published in almanacs which were computed and issued by special ephemeris institutes. We describe the agreements on the international exchange of ephemerides which were reached in peace times, and the continuation of this exchange during the war using intermediaries in neutral countries, first in the USA (U.S. Naval Observatory, USNO), and, from 1942 onwards, in Sweden (Stockholm Observatory). Involved persons were especially H. Spencer Jones (Astronomer Royal, Greenwich), J. F. Hellweg und W. J. Eckert (USNO), B. Lindblad (Sweden), and A. Kopff (ARI). All those relevant documents which are hold in the archives of the ARI, are described and annotated in detail. Scans of these documents are presented in a separate supplement.

  19. Trauma and the full moon: a waning theory.

    Coates, W; Jehle, D; Cottington, E

    1989-07-01

    There exists a popular belief in the causal relationship between the moon's phase and the incidence of major trauma. In this retrospective study we reviewed 1,444 trauma victims admitted to the hospital during one calendar year. Full moons were defined as three-day periods in the 29.531-day lunar cycle, with the middle day being described in the world almanac as the full moon. Victims of violence included those patients sustaining blunt assault, gunshot wounds, and stabbings. There was no statistical difference in number of trauma admissions between the full moon, 129 patients per 36 days (mean, 3.58), and nonfull moon days, 1,315 patients per 330 days (mean, 3.98). Mortality rate, 5.4% versus 10.3%; mean Injury Severity Score, 13 versus 15; and mean length of stay, ten versus 12 days, were not significantly different during the full moon and nonfull moon days. Victims of violence were admitted at a similar frequency on full moon, 16 patients per 36 days (mean, 0.444), and nonfull moon days, 183 patients per 330 days (mean, 0.555). We conclude that the belief in the deleterious effects of the full moon on major trauma is statistically unfounded.

  20. An approximation to the outer planet ephemeris errors in JPL's DE 200

    1990-01-01

    The outer planet positions of JPL's recent planetary ephemeris, DE 202, have begun to show significant differences from DE 200, the basic ephemeris of the major national almanacs. The differences DE 202 - DE 200 are plotted and are assumed to approximate the errors of DE 200. For Jupiter, the difference in right ascension varies over the planet's 12 yr period between -0.1 and -0.2 arcsec throughout the century; for Saturn, the right ascension also varies over the 30 yr period, but in addition, shows a drift which reaches -0.25 arcsec at present; for Uranus, the difference is small through the first half of the century, but now has reached -0.4 arcsec; for Neptune, the error was +0.6 arcsec at 1900 and is near -1.0 arcsec by the year 2000; the error for Pluto exceeds +2.0 arcsec by the end of the century and is rapidly increasing. The declination errors are generally periodic and smaller than the right ascensions.

    2004-01-01

    NASA Goddard Space Flight Center (GSFC) is developing a new space-borne GPS receiver that can operate effectively in the full range of Earth orbiting missions from Low Earth Orbit (LEO) to geostationary and beyond. Navigator is designed to be a fully space flight qualified GPS receiver optimized for fast signal acquisition and weak signal tracking. The fast acquisition capabilities provide exceptional time to first fix performance (TIFF) with no a priori receiver state or GPS almanac information, even in the presence of high Doppler shifts present in LEO (or near perigee in highly eccentric orbits). The fast acquisition capability also makes it feasible to implement extended correlation intervals and therefore significantly reduce Navigator s acquisition threshold. This greatly improves GPS observability when the receiver is above the GPS constellation (and satellites must be tracked from the opposite side of the Earth) by providing at least 10 dB of increased acquisition sensitivity. Fast acquisition and weak signal tracking algorithms have been implemented and validated on a hardware development board. A fully functional version of the receiver, employing most of the flight parts, with integrated navigation software is expected by mid 2005. An ultimate goal of this project is to license the Navigator design to an industry partner who will then market the receiver as a commercial product.

    More and more Global Navigation Satellite Systems (GNSSs) have been developed and are in operation. Before integrating information on various GNSSs, the differences between the various systems must be studied first. This research focuses on analyzing the navigation data differences between the Chinese BeiDou Navigation Satellite System (BDS) and the United States' Global Positioning System (GPS). In addition to explaining the impact caused by these two different coordinate and time systems, this research uses an actual open service signal in space (SIS) for both GPS and BDS to analyze their current system performance. Five data quality analysis (DQA) mechanisms are proposed in this research to validate both systems' SIS navigation data. These five DQAs evaluate the differences in ephemeris and almanac messages from both systems for stability and accuracy. After all of the DQAs, the different issues related to GPS and BDS satellite information are presented. Finally, based on these DQA results, this research provides suggested resolutions for the combined use of GPS and BDS for navigation and guidance.

  3. CALCM: The untold story of the weapon used to start the Gulf war

    The Conventional Air Launched Cruise Missile (CALCM) was developed from the strategic ALCM, AGM-86, by integrating GPS navigation into the missile in place of terrain correlation (TERCOM). In addition, the nuclear warhead was replaced by conventional explosives. The CALCM was developed, tested, and fielded in a single year (mid-1986 - mid-1987) by the Boeing Company where the author was then employed. Although the GPS technology used, a Rockwell single channel aided receiver, has been eclipsed by newer receivers with additional capabilities and newer technology, many innovative things were done in completing the CALCM integration: the external loading of almanac data along with other mission data, three satellite navigation capability, and the use of a single channel receiver in a dynamic flight environment. This effort demonstrated that GPS outputs can be integrated quickly into an existing weapon system using the traditional loosely coupled 'cascaded filter' approach. Although this approach is not as ideal as a tightly coupled integration using raw GPS data, the use of cascaded filters resulted in a weapon that was able to be rapidly fielded. The Air Force had sufficient confidence in the missile, that after four years of operational testing, 35 of these missiles were targeted at key sites at the start of the Gulf War in 1991. This effort, which was declassified in 1992, resulted in the first weapon in the DoD inventory to be operational using GPS navigation. The effort deserves consideration as a model as to how GPS integration can be performed.

    Personal characteristics of patients and environmental factors at psychiatric hospitals have been identified as predictors of absconding. This study seeks to establish a relationship between time of the year and absconding. All characteristics of absconders were analysed over a two-year period using hospital records (N= 104). Public holidays and lunar phases were obtained through almanacs for each year; and school vacation period was determined by reference to a school academic calendar. Friday was the most popular day of the week for absconding, males tend to escape more on the weekends compared to females, females tend to escape more during the wet season, and Christmas was the most popular holiday season for absconding to take place. The full moon phase had the largest percentage of absconding when compared to other phases. Recommendations are that the system of patient care should be client driven at all times and greater supervision of patients is needed on weekends, vacation periods and during the full moon phase.

Although many unicentric and multicentric observational studies validated by complete axillary dissection could demonstrate that SNB is accurate and suitable for all operable clinically node-negative breast cancers, longterm results and especially the incidence of axillary recurrence and its sequelae are outstanding. Findings of ongoing large prospective randomized trials like NSABP 32, Z0010 and Z0011 of the American College of Surgeons (ACOSOG), the AMAROS-Trial of the European Organisation of Research and Treatment of Cancer (EORTC) and the ALMANAC-Trial of the British Association of Surgical Oncology (BASO) will give a conclusive answer. Significant improvement in morbidity and quality of life measurements could be revealed several times in unicentric and even in muticentric studies like ALMANAC. Sentinel node biopsy is a team approach, requirements are good cooperation and well-defined stuctures of quality indicators and documentation. Participation in national clinical studies is recommended.

    Seidelmann, P. Kenneth

    2004-12-01

    Julena Steinheider Duncombe died on 13 September 2003, just eight days before her 92nd birthday. Julena Steinheider was born September 21, 1911 on a farm in Dorchester, Nebraska and grew up in Goehner, Nebraska. Her parents were Frederick and Ella Beenders Steinheider, and she had four brothers. She began college at the age of 17 and graduated at 21 from Doane College in Crete, Nebraska with a major in mathematics and a minor in astronomy. She started teaching in a one-room schoolhouse, where, with assistance from her family, she started possibly the first school lunch program by fixing lunches on the schoolhouse stove to provide food for children who only had popcorn to eat. Then she taught in Minatare and Scotts Bluff, Nebraska, and in a Japanese Relocation Camp in Wyoming. In 1945 she moved to Washington DC to begin working at the US Naval Observatory (USNO). She was the first woman observer on the 6-inch transit circle. She worked as an observer and mathematician reducing and analyzing observations of the Sun, Moon, planets, and stars. At the Naval Observatory she met Raynor Duncombe and married him in Goehner, Nebraska, in January 1948. She resigned from the USNO in 1948 to go with her husband to Yale University. At Yale the Duncombes introduced punched card equipment into the Astronomy Department. Ray also took graduate classes and Julie worked on Astrographic Catalog reductions. Upon returning to USNO in 1950 she joined the Nautical Almanac Office. She supervised the punched card operated typewriter to produce tables of positions of celestial bodies for air and sea navigation. With Dorrit Hoffleit she directed the keypunching of over 150 star catalogs, approximating 1.5 million cards. Several thousand errata to the catalogs were discovered and corrected on the cards and tape versions of the catalogs. This activity was the basis for future stellar databases. From 1963 she was responsible for producing the tabular predictions and maps for solar and lunar

  8. Calendars in the Gregorian Spirit

    Lichtenberg, Heiner; Richter, Peter H.

    The Gregorian Calendar is an adaptable cyclic, lunisolar time-reckoning system [1]. It assumes the following equations: atrop &=& 1461/4 - s/(100 × P1) quad days msyn &=& atrop / (235/19 + e/(3000 × P2))quad day s for the average tropical year atrop and the average synodical month msyn, respectively [2]. s is the number of leap years reverting to common years at the secular boundaries of the period P1, measured in centuries. e is the number of (net) adjustments of the epact at the secular boundaries of the period P2, measured in centuries. The particular form of this rational approximation characterizes the Gregorian spirit; the standard integers s = 3, P1 = 4, e = -43, P2 = 100 are open for adjustment. Truncated continued fraction expansions should be used to successively improve the accuracy. For atrop = 365.2422 d and msyn = 29.530588 d, we find that s = 3, P1 = 4, e = -19, P2 = 44 is slightly better than the standard values. Its fundamental equation 2,508,000 atrop = 31,019,639 msyn = 916,028,190 d defines a period about half as long as for the usual Gregorian calendar, 5,700,000 atrop = 70,499,183 msyn = 2,081,882,250 d [3].

    Genetic variants of ESR1 have been implicated in multiple diseases, including behavioral disorders, but causative variants remain uncertain. We have searched for regulatory variants affecting ESR1 expression in human brain, measuring allelic ESR1 mRNA expression in human brain tissues with marker SNPs in exon4 representing ESR1-008 (or ESRα-36), and in the 3'UTR of ESR1-203, two main ESR1 isoforms in brain. In prefrontal cortex from subjects with bipolar disorder, schizophrenia, and controls (n = 35 each; Stanley Foundation brain bank), allelic ESR1 mRNA ratios deviated from unity up to tenfold at the exon4 marker SNP, with large allelic ratios observed primarily in bipolar and schizophrenic subjects. SNP scanning and targeted sequencing identified rs2144025, associated with large allelic mRNA ratios (p = 1.6E10-6). Moreover, rs2144025 was significantly associated with ESR1 mRNA levels in the Brain eQTL Almanac and in brain regions in the Genotype-Tissue Expression project. In four GWAS cohorts, rs2104425 was significantly associated with behavioral traits, including: hypomanic episodes in female bipolar disorder subjects (GAIN bipolar disorder study; p = 0.0004), comorbid psychological symptoms in both males and females with attention deficit hyperactivity disorder (GAIN ADHD, p = 0.00002), psychological diagnoses in female children (eMERGE study of childhood health, subject age ≥9, p = 0.0009), and traits in schizophrenia (e.g., grandiose delusions, GAIN schizophrenia, p = 0.0004). The first common ESR1 variant (MAF 12-33% across races) linked to regulatory functions, rs2144025 appears conditionally to affect ESR1 mRNA expression in the brain and modulate traits in behavioral disorders.

    Field studies that address the production of lignocellulosic biomass as a source of renewable energy provide critical data for the development of bioenergy crop models. A literature survey revealed that 14 models have been used for simulating bioenergy crops including herbaceous and woody bioenergy crops, and for crassulacean acid metabolism (CAM) crops. These models simulate field-scale production of biomass for switchgrass (ALMANAC, EPIC, and Agro-BGC), miscanthus (MISCANFOR, MISCANMOD, and WIMOVAC), sugarcane (APSIM, AUSCANE, and CANEGRO), and poplar and willow (SECRETS and 3PG). Two models are adaptations of dynamic global vegetation models and simulate biomass yields of miscanthus and sugarcane at regional scales (Agro-IBIS and LPJmL). Although it lacks the complexity of other bioenergy crop models, the environmental productivity index (EPI) is the only model used to estimate biomass production of CAM (Agave and Opuntia) plants. Except for the EPI model, all models include representations of leaf area dynamics, phenology, radiation interception and utilization, biomass production, and partitioning of biomass to roots and shoots. A few models simulate soil water, nutrient, and carbon cycle dynamics, making them especially useful for assessing the environmental consequences (e.g., erosion and nutrient losses) associated with the large-scale deployment of bioenergy crops. The rapid increase in use of models for energy crop simulation is encouraging; however, detailed information on the influence of climate, soils, and crop management practices on biomass production is scarce. Thus considerable work remains regarding the parameterization and validation of process-based models for bioenergy crops; generation and distribution of high-quality field data for model development and validation; and implementation of an integrated framework for efficient, high-resolution simulations of biomass production for use in planning sustainable bioenergy systems.

    In anticipation of the 2017 August 21 total solar eclipse over the continental United States, the history of U.S. Naval Observatory eclipse observations illustrates the changes in science, technology, and policy over the past 148 years.USNO eclipse observations began in 1869, when staff traveled to Des Moines, Iowa and the Bering Strait to look for intra-mercurial planets and to observe the solar corona. During the golden age of eclipse expeditions, the USNO officially participated in a dozen expeditions between 1869 and 1929. Seven of these expeditions were to US locations: 1869 in Iowa; 1878 in Colorado, Wyoming, and Texas; 1880 in California; 1900 in Georgia and North Carolina; 1918 in Oregon; 1923 in California; and 1925 in New York. A total solar eclipse has not traced a path across the width of the continental US since 1918 although several eclipses have passed over parts of the US since then.A few official expeditions occurred later in the 20th century to measure the solar diameter, including a total eclipse in the northwest US in 1979 and an annular eclipse across the southeast in 1984. However, observations began transitioning to mostly personal adventures as individual astronomers arranged unofficial trips.Historians can use the USNO Multi-year Interactive Computer Almanac (MICA) to compute local circumstances for solar eclipses world-wide starting with the annual eclipse of 1800 April 24, which was visible from Alaska. Those looking to make history in 2017 may consult the USNO 2017 August 21 Solar Eclipse Resource page (http://aa.usno.navy.mil/data/docs/Eclipse2017.php).

    Gamma-amino butyric acid (GABA) and glutamate are the major inhibitory and excitatory neurotransmitters in the mammalian central nervous system, respectively, and have been associated with suicidal behavior and major depressive disorder (MDD). We examined the relationship between genotype, brain transcriptome, and MDD/suicide for 24 genes involved in GABAergic and glutamatergic signaling. In part 1 of the study, 119 candidate SNPs in 24 genes (4 transporters, 4 enzymes, and 16 receptors) were tested for associations with MDD and suicidal behavior in 276 live participants (86 nonfatal suicide attempters with MDD and 190 non-attempters of whom 70% had MDD) and 209 postmortem cases (121 suicide deaths of whom 62% had MDD and 88 sudden death from other causes of whom 11% had MDD) using logistic regression adjusting for sex and age. In part 2, RNA-seq was used to assay isoform-level expression in dorsolateral prefrontal cortex of 59 postmortem samples (21 with MDD and suicide, 9 MDD without suicide, and 29 sudden death non-suicides and no psychiatric illness) using robust regression adjusting for sex, age, and RIN score. In part 3, SNPs with subthreshold (uncorrected) significance levels below 0.05 for an association with suicidal behavior and/or MDD in part 1 were tested for eQTL effects in prefrontal cortex using the Brain eQTL Almanac (www.braineac.org). No SNPs or transcripts were significant after adjustment for multiple comparisons. However, a protein coding transcript (ENST00000414552) of the GABA A receptor, gamma 2 (GABRG2) had lower brain expression postmortem in suicide (P = 0.01) and evidence for association with suicide death (P = 0.03) in a SNP that may be an eQTL in prefrontal cortex (rs424740, P = 0.02). These preliminary results implicate GABRG2 in suicide and warrant further investigation and replication in larger samples.

    The Spitz Fulldome Curriculum (FDC) for the SciDome digital planetarium ushered in a new and innovative way to present astronomical pedagogy via its use of the unique teaching attributes of the digital planetarium. In the case of the FDC, which uses the ubiquitous Starry Night planetarium software as its driving engine, these engaging and novel teaching techniques have also been made usable to desktop computers and flat-screen video projectors for classroom use. Volume 2 of the FDC introduces exciting new classes and mini-lessons to further enlighten and invigorate students as they struggle with often difficult three dimensional astronomical concepts. Additionally, other topics with related astronomical ties have been created to integrate history into planetarium presentations. One of the strongest advantages of the SciDome is its use of Starry Night as its astronomical engine. With it students can create their own astronomical configurations in the computer lab or at home, using the PC or Mac version. They can then simply load their creations onto the SciDome planetarium system and display them for their classmates on the dome. This poster will discuss and illustrate some of the new content that has been developed for Volume 2. Topics covered in Volume 2 include eclipses, plotting planet locations on a curtate orbit chart by observing their positions in the sky, time and timekeeping (including sidereal day, hour angles, sidereal time, LAST, LMST, time zones and the International Date Line), teaching to the Boy Scout Merit Badge requirements, plotting scale analemmas on the surface of planets and interpreting them, precession, astronomical events in revolutionary Boston, the Lincoln Almanac Trial, eclipsing binaries, lunar librations, a trip through the universe, watching the speed of light move in real time, stellar sizes and the Milky Way.

  14. The Newcomb-Michelson velocity of light experiments

    Carter, Wiiliam E.; Carter, Merri Sue

    In 1877, at age 42, Simon Newcomb became the superintendent of the Nautical Almanac Office (NAO), U.S. Naval Observatory in Washington D.C. That same year, at age 25, Ensign Albert Michelson began his new assignment as a professor of physics and chemistry at the U.S. Naval Academy in Annapolis, Maryland [Reingold, 1964]. While they worked for the same agency less than 1 hour apart by train, the two men lived in very different worlds. Newcomb had already achieved international acclaim for his studies of the orbits of Neptune and Uranus and had his choice of any number of prestigious and powerful positions at scientific institutions and astronomic observatories throughout the nation. As a junior naval officer Michelson could, at best, expect to spend a few years teaching at the Naval Academy before being reassigned to sea duty. Within 2 years of graduating, Michelson had already served aboard five ships of the line, sailing to ports as distant as Rio de Janeiro [Livingston, 1973]. Newcomb had direct access to the secretary of the Navy and members of Congress, and when he learned that Michelson had begun to work on velocity of light experiments, he did not hesitate in having the young ensign detailed to the Naval Observatory. Together they assembled and perfected an apparatus that measured the velocity of light more accurately than had ever been possible before, and the value obtained from the complete set of experiments performed in Washington—299,810 km/s—was not bettered for more than 4 decades.

  15. Hawk and Handsaw

    NASA Astrophysics Data System (ADS)

    Usher, Peter D.

    2008-05-01

    In Shakespeare's Hamlet, Prince Hamlet states, "I am but mad north-north-west. When the wind is southerly, I know a hawk from a handsaw." This celebrated yet perennially baffling passage is readily understood in the context of the cosmic allegorical interpretation of the play (BAAS 28, 1305, 1996; Hamlet's Universe, 2006). The first direction points from Tycho Brahe's observatory on Hven to the fictional home of the geocentric Pyolemaic worldview at Elsinore, and the second from Hven to the home of Copernican heliocentricism at Wittenberg. The directions correspond to the two influences on Tycho's geo-heliocentric World model. Anyone at Elsinore who advocates the new organon of the New Philosophy is "mad," whereas sanity prevails at Wittenberg. "Hawk" refers to a bird of prey, the leonard, and to Leonard Digges, inventor of the world's first two-element telescope. "Handsaw" refers to the artistic tool necessary to sever the hands depicted in de Gheyn's two quasi-mirror-imaged portraits of Tycho at age 40, which show hands affixed to the wrong arms. Elsewhere in Hamlet, Shakespeare substantiates the New Astronomy through descriptions of planets and stars that could only have been determined telescopically. Therefore, the passage in question contrasts two modes of observing in the early modern era, viz. visual and telescopic. Shakespeare completed writing Hamlet in about 1601 and the Second Quarto appeared in 1604, so the first substantial account of astronomical telescopy is now over 400 years old. In addition, 432 years ago Thomas Digges published the first account of the New Astronomy in a popular almanac. These two means of presentation may seem odd by present standards, but contemporary culture was intolerant of 'natural magic,' and furthermore, it was prudent to minmize the risk of domestic persecution and threats from Continental armies and the European and Spanish Inquisitions.

    High biomass production potential, wide adaptability, low input requirement, and low environmental risk make switchgrass an economically and ecologically viable energy crop.The inherent variablity in switchgrass productivity due to variations in soil and variety could affect the sustainability and eco-friendliness of switchgrass-based ethanol production. This study examined the soil and variety effects on these variables. Three locations in Mississippi were selected based on latitude and potential acreage. Using ALMANAC, switchgrass biomass yields were simulated for several scenarios of soils and varities. The simulated yields were fed to IBSAL to compute energy use and CO2 emissions in various operations in the biomass supply From the energy and emissions values, the sustainability and eco-friendliness of ethanol production were determined using net energy value (NEV) and carbon credit balance (CCB) as indicators, respectively. Soil and variety effects on NEV and CCB were analyzed using the Kruskal-Wallis test. Results showed significant differences in NEV and CCB across soils and varieties. Both NEV and CCB increased in the direction of heavier to lighter soils and on the order of north-upland , south-upland, north-lowland, and south-lowland varieties. Only north-upland and south-lowland varieties were significantly significantly different because they were different in both cytotype and ecotype. Gaps between lowland and upland varieties were smaller in a dry year than in a wet year. The NEV and CCB increased in the direction of dry to wet year. From south to north, they decreased for lowland cytotypes but increased for upland cytotypes. Thus, the differences among varieties decreased northwards.

  17. Tools for Implementing the Recent IAU Resolutions: USNO Circular 179 and the NOVAS Software Package

    The resolutions on positional astronomy adopted at the 1997 and 2000 IAU General Assemblies are far-reaching in scope, affecting both the details of various computations and the basic concepts upon which they are built. For many scientists and engineers, applying these recommendations to practical problems is thus doubly challenging. Because the U.S. Naval Observatory (USNO) serves a broad base of users, we have provided two different tools to aid in implementing the resolutions, both of which are intended for the person who is knowledgeable but not necessarily expert in positional astronomy. These tools complement the new material that has been added to The Astronomical Almanac (see paper by Hohenkerk). USNO Circular 179 is a 118-page book that introduces the resolutions to non-specialists. It includes extensive narratives describing the basic concepts as well as compilations of the equations necessary to apply the recommendations. The resolutions have been logically grouped into six main chapters. The Circular is available as a hard-cover book or as a PDF file that can be downloaded from either the USNO/AA web site (http://aa.usno.navy.mil/) or arXiv.org. NOVAS (Naval Observatory Vector Astrometry Subroutines) is a source-code library available in both Fortran and C. It is a long established package with a wide user base that has recently been extensively revised (in version 3.0) to implement the recent IAU resolutions. However, use of NOVAS does not require detailed knowledge of the resolutions, since commonly requested high-level data _ for example, topocentric positions of stars or planets _ are provided in a single call. NOVAS can be downloaded from the USNO/AA web site. Both Circular 179 and NOVAS version 3.0 anticipate IAU adoption of the recommendations of the 2003-2006 working groups on precession and nomenclature.

    With the total solar eclipse of 2017 August 21 over the continental United States approaching, the U.S. Naval Observatory (USNO) on-line Solar Eclipse Computer can now be accessed via an Android application, available on Google Play.Over the course of the eclipse, as viewed from a specific site, several events may be visible: the beginning and ending of the eclipse (first and fourth contacts), the beginning and ending of totality (second and third contacts), the moment of maximum eclipse, sunrise, or sunset. For each of these events, the USNO Solar Eclipse 2017 Android application reports the time, Sun's altitude and azimuth, and the event's position and vertex angles. The app also lists the duration of the total phase, the duration of the eclipse, the magnitude of the eclipse, and the percent of the Sun obscured for a particular eclipse site.All of the data available in the app comes from the flexible USNO Solar Eclipse Computer Application Programming Interface (API), which produces JavaScript Object Notation (JSON) that can be incorporated into third-party Web sites or custom applications. Additional information is available in the on-line documentation (http://aa.usno.navy.mil/data/docs/api.php).For those who prefer using a traditional data input form, the local circumstances can still be requested at http://aa.usno.navy.mil/data/docs/SolarEclipses.php.In addition the 2017 August 21 Solar Eclipse Resource page (http://aa.usno.navy.mil/data/docs/Eclipse2017.php) consolidates all of the USNO resources for this event, including a Google Map view of the eclipse track designed by Her Majesty's Nautical Almanac Office (HMNAO).Looking further ahead, a 2024 April 8 Solar Eclipse Resource page (http://aa.usno.navy.mil/data/docs/Eclipse2024.php) is also available.

  19. It's About Time:Mark Twain's ``My Watch'' and Relativity

    NASA Astrophysics Data System (ADS)

    Henderson, Hugh

    2005-09-01

    Over three decades before Einstein's year of miracles, the American humorist Mark Twain published an essay titled "My Watch," in which he recounts his experiences with a previously reliable pocket watch and those who tried to rehabilitate it. He begins his essay by confessing his first error: My beautiful new watch had run eighteen months without losing or gaining, and without breaking any part of its machinery or stopping. I had come to believe it infallible in its judgments about the time of day, and to consider its constitution and its anatomy imperishable. But at last, one night, I let it run down. I grieved about it as if it were a recognized messenger and forerunner of calamity. Twain then sets the watch by guess, and takes it to the "chief jeweler's to set it by the exact time." To Twain's dismay, the jeweler insists on opening it up and adjusting the regulator inside the watch, and the watch begins to gain time. It gained faster and faster day by day. Within a week it sickened to a raging fever, and its pulse went up to a hundred and fifty in the shade. At the end of two months, it had left all the timepieces of the town far in the rear, and was a fraction over thirteen days ahead of the almanac. It was away into November enjoying the snow, while the October leaves were still turning. It hurried up house rent, bills payable, and such things, in such a ruinous way that I could not abide it.

    This is a brief note to a problem on the Rift Valley in the eastern Africa. It is said that this valley was formed in an age 20,000,000 years before present though the valley is yet continuing to move eastward at an annual rate of about 5 cm/year in a geographical trend. Adding to some of the scientists tell that the separation threat of the easternAfrica from the mother land of the Africa under the effect of African crust motion over the magma. However, it is now geological understanding that the land of the Africa has been kept its basic coastal configulation in geographic pattern since the time more than 20,000,000 years before present. Sothat, it is hard to consider the above noted African land separation by part could be in the next age in a time scale of 20,000,000 years. As far as, we concern the geographic data obtaoned by the ground based survey of the African typical mountain peaks, the highest mountain peak 5885m (in 1980) is for Kilimanjaro, Kibo Peak though one of the scientific almanacs tells us its peak height as 5890m (in 2009). As for the Mount Kenia, the peak height is as 5199m (in 1980) and 5200m(in 2009). At a glance, it looks to be a trend in altimetry of the African typical mountain. Now, what trends are noted for the peak heights could be taken to suggesting the geological activity on the earth surface to maintain in a spherical shape approximately on the orbit around the Sun. In these several ten years, the digitizing of the data has been promoted even for the topographic patterns on the earth though its time scaling is extremely short comparing to the geological time scaling. Now, it should be found what is effective to monitor any trends of the African crust in motion as well as variations of the mountain peaks.

  1. Ancient Indian astro-mathematical tradition: Evolution and linkages

    Indian astronomical tradition is characterized by antiquity, continuity and interaction with the outside world. From 6th century CE till the time of Kepler's laws, Indian astronomers were probably the only ones in the world who could calculate eclipses with any degree of accuracy. In the 12th century, an astronomer in Central India, Padmanabha by name, predicted the lunar eclipse of 8 November 1128 and was rewarded by the king with a land grant (Mirashi 1933-34). The tradition was alive well into the 19th century. By means of shells arranged on the ground and using mathematical tables memorized ``by means of certain artificial words and syllables'', a ``Kalendar maker residing in Pondicherry'' calculated the lunar eclipse of 31 May-1 June 1825, with an error of no more than +4 minutes for the beginning (Neugebauer 1983, p. 436). Even now, traditional astronomical almanacs in India, known as panchangas, used in India for ritual and religious purposes base their calculations on ancient texts. It is only in the case of eclipse that they borrow data from modern sources. The beginnings of astronomy are related to the requirements of the ritual in early cultures. Ritual was seen as a means of securing divine approval and support for terrestrial actions. To be effective, it had to be elaborate and welltimed, so that a careful distinction could be made between auspicious and inauspicious times. Since planetary motions provided a natural means of time keeping and were seen as embodiment of divine signals, astronomy developed as an intellectual discipline (see Yano 2003). Similarly mathematics grew as an aid to designing sacrificial altars. The oldest geometry texts in India are the Sulvasutras which dealt with questions like the square root of two. Different scholars place the earlier of these texts anywhere between 800 BCE and 400 BCE. Astronomy texts are decidedly older. Subsequent developments in mathematics came about as an astronomical aid.

    We, as water resource professionals, are faced with a truly monumental challenge - that is feeding the world's growing population and ensuring it has an adequate supply of clean water. As researchers and educators it is good for us to regularly remember that our research and outreach efforts are critical to people around the world, many of whom are desperate for solutions to water quality and supply problems and their impacts on food supply, land management, and ecosystem protection. In this presentation, recommendations for successful applied research on agricultural impacts on water resources will be provided. The benefits of building multidisciplinary teams will be illustrated with examples related to the development and world-wide application of the ALMANAC, SWAT, and EPIC/APEX models. The value of non-traditional partnerships will be shown by the Soil Health Partnership, a coalition of agricultural producers, chemical and seed companies, and environmental advocacy groups. The results of empowering decision-makers with useful data will be illustrated with examples related to bacteria source and transport data and the MANAGE database, which contains runoff nitrogen and phosphorus data for cultivated, pasture, and forest land uses. The benefits of focusing on sustainable solutions will be shown through examples of soil testing, fertilizers application, on-farm profit analysis, and soil health assessment. And the value of welcoming criticism will be illustrated by the development of a framework to estimate and publish uncertainty in measured discharge and water quality data. The good news for researchers is that the agricultural industry is faced with profitability concerns and the need to wisely utilize soil and water resources, and simultaneously state and federal agencies crave sound-science to improve decision making, policy, and regulation. Thus, the audience for and beneficiaries of agricultural research are ready and hungry for applied research results.

    The interest of man in outer space began long ago among uncivilized peoples to whom the face of the sky was clock and almanac; the celestial bodies, objects of worship. Exploration was at first by visual observation, later aided by armillary spheres and quadrants, and still later by more precise measuring instruments, telescopes, and spectroscopes. The information obtained was that borne by the light that was transmitted from the distant celestial object through the atmosphere to the observing instrument on the ground. In recent years the light waves have been supplemented by radio waves as carriers of information from the stars and planets. Men of many nations have contributed through the centuries to the exploration of space by the methods of astronomy. The history of advances in astronomical knowledge and technique includes the records of Chinese, Babylonians, Greeks, Arabians, and of nearly every nation of the modern world. International cooperation was early recognized as essential and beneficial; the countless number of the stars and the vastness of space present mankind with a truly global task. The picture of the universe obtained by the astronomers early stirred the imagination of men to speculate about the existence of life elsewhere in the universe, about means of communication with distant stars, and in the last centuries about the possibility of the travel of man to the moon and planets. Some sought to apply the science and engineering of their day to describe the vehicles to be used. For example, Jules Verne published in 1865 in "From the Earth to the Moon" a description of a gun-launched projectile carrying passengers to orbit the moon. Today we have taken the first steps to bring this inspired vision to reality. The exploration of space by unmanned vehicles carrying scientific apparatus began on October 4, 1957; exploration by man will follow in due course.

    How do astronomical methods make it possible to calculate dates and times for Vincent van Gogh's night-sky paintings? Why is there a blood-red sky in Edvard Munch's The Scream? How can the 18.6-year cycle of the lunar nodes and the Moon's declination on the night of August 29-30, 1857, explain a long-standing mystery about Abraham Lincoln's honesty in the murder case known as the almanac trial? Why is a bright star described in Act 1, Scene 1, of Hamlet? There is a long tradition of astronomical methods employed to analyze works of art, to understand historical events, and to elucidate passages in literature. Both Edmond Halley and George Biddell Airy calculated lunar phases and tide tables in attempts to determine the landing beach where Julius Caesar invaded Britain in 55 B.C. Henry Norris Russell computed configurations of Jupiter and Saturn to determine a date for a 14th-century celestial event mentioned in Chaucer's Troilus and Criseyde. In this tradition, our Texas State group has published a series of articles in Sky & Telescope over the last two decades, applying astronomy to art, history, and literature. Don Osterbrock worked with us 3 years ago when my students and I calculated dates for moonrise photographs taken by Ansel Adams in Yosemite National Park. The peaks of the Sierra Nevada crest in Yosemite are more than 125 miles from Lick Observatory, but the mountains can become visible from Lick on clear winter days and were photographed from there on early infrared-sensitive plates during the 1920s and 1930s. As we tested our topographic software by identifying the peaks that appear in the Lick plates, it was a pleasure to come to know Don, a former director of Lick Observatory and the person in whose honor this talk is dedicated.

    George William Hill (1838-1914) has long been considered one of the most famous and talented celestial mechanicians of the past century and a half. However, many people have never heard of him and his work. Simon Newcomb said he "will easily rank as the greatest master of mathematical astronomy during the last quarter of the nineteenth century.” After receiving a B.A. at Rutgers in 1859, Hill began work in 1861 at the office of the American Ephemeris and Nautical Almanac in Cambridge, MA. He moved to Washington with the group in 1882 which then became part of the U. S. Naval Observatory. Newcomb, beginning his work on planetary motion, assigned the theory of Jupiter and Saturn to him, calling it about the most difficult topic. Hill's work was published by the USNO in 1890 as A New Theory of Jupiter and Saturn. From 1898 to 1901, Hill lectured on the subject of celestial mechanics at Columbia University in a position created just for him. After 1892 and until his death, he lived at the family homestead in West Nyack, NY. He never married, was something of a recluse, and spent most of his time with his books and research. Hill was an amateur botanist and enjoyed exploring on long walks in the countryside. Many honors and awards came to him during his lifetime, both from the U.S. and abroad, including serving as president of the American Mathematical Society. All of Hill's mathematical and astronomical research was incorporated in The Collected Mathematical Works of George William Hill. This work, containing a preface in French by Poincare, was published in 4 large volumes by the Carnegie Institution of Washington in 1905.

    The Astronomical Almanac lists Mt.Evans Observatory as the world's highest (Georgetown, Colorado, elev. 4,313 meters). We report on site observations conducted since our initial report (1993 Bull.A.A.S. 24:1240). Evidence will be provided that the site is competitive with the best, currently operational optical-infrared sites. The elevation difference between Denver and the summit is 9,000 feet, which strongly reduces the scattered light contribution to sky brightness. Astronomical seeing tests, as well as regional cloud cover statistics will be presented. The mid-continental location and elevation are responsible for minimal amounts of precipital water vapor (directly measured at 0.8mm in 1993 Sept. and estimated from observed temperature, pressure and relative humidity at the site to be even lower in winter months), giving the Mt.Evans site excellent infrared transparency. Three years of automated weather station data from the summit show the daily and annual temperature variations to be far from extreme, and the average wind field peaks daily at 20 knots out of the west. The treeless summit topography is favorable for laminar flow, which enhances optical/infrared image quality. Because Mt. Evans offers a potentially superior observatory site, we will also address the possiblities for future telescope development. The summit is easily accessible via a paved State Highway, and the unobstructed line of sight to the DU campus enhances the possibilities for remote operations. We are grateful to the estate of William Herschel Womble for providing funds in support of this investigation.

  8. Simon Marius vs. Galileo: Who First Saw Moons of Jupiter?

    In his almanac for 1612 and book Mundus Iovalis of 1614, Simon Marius in Germany reported his discovery of moons around Jupiter, which he started writing down in late 1609 in the Julian calendar, which translated to 8 January 1610 in the Gregorian calendar in use by Galileo in Italy. Is Marius to be believed? Galileo certainly did not. But a Dutch jury of experts about three hundred years later reported that they validated the claim that Marius independently discovered the moons of Jupiter one day after Galileo first both saw and wrote down his discovery! There is no doubt that the names Io, Europa, Ganymede, and Callisto came from Marius (to whom they were suggested by Kepler). See JMP's Journal for the History of Astronomy article, 46(2), 218-234 (2015).Marius wrote that he had been observing the moons around Jupiter since November 1609 (Julian), using a neighboring nobleman's telescope, which would mean that he actually saw the Jupiter satellites first (though publish or perish). Whether this feat was technically possible comes down to discussions of the capabilities of telescopes in the early 17th century.The quadricentennial of Marius's book was celebrated in Nuremberg with a symposium that is now in press in German with an English translation expected. One of us (AVH) has recently prepared a complete English translation of Marius's book, superseding the partial translation made 100 years ago. There is no evidence that, whether he saw what we now call the Galilean satellites first or not, Marius appreciated their cosmological significance the way that Galileo soon did. And Marius was certainly the first to publish tables of the moons of Jupiter.We thank the Chapin Library of Williams College and the Huntington Library for assistance with first editions of Marius's 1614 book, and we thank Pierre Leich of the Simon Marius Gesellschaft for his consultations.

    Field studies that address the production of lignocellulosic biomass as a potential source of renewable energy are making available critical information for the development, validation, and use of bioenergy crop models. A literature survey revealed that 14 models have been developed and validated for herbaceous and woody bioenergy crops, and for Crassulacean acid metabolism (CAM) crops adapted to arid lands. These models simulate field-scale production of biomass for switchgrass (ALMANAC, EPIC, and Agro-BGC), miscanthus (MISCANFOR, MISCANMOD, and WIMOVAC), sugarcane (APSIM, AUSCANE, and CANEGRO), and poplar and willow (SECRETS and 3PG). Two models are adaptations of dynamic global vegetation models and simulate biomass yields of miscanthus and sugarcane as plant function types at regional scales (Agro-IBIS and LPJmL). A model of biomass production in CAM plants has been developed (EPI), but lacks the sophistication of the other models. Except for CAM plants, all the models include representations of leaf area dynamics, radiation interception and utilization, biomass production, and partitioning of biomass to roots and shoots. A few of the models are capable of simulating soil water, nutrient, and carbon cycle processes, making them especially useful for assessing environmental consequences (e.g., erosion and nutrient losses) associated with the field-scale deployment of bioenergy crops. Similar to other process-based models, simulations are challenged by computing and data management issues and an integrated framework for model testing and inter-comparison is needed. Considerable work remains concerning the development of models for unconventional bioenergy crops like CAM plants, generation and distribution of high-quality field data for model development and validation, and development of an integrated framework for efficient execution of large-scale simulations for use in planning regional to global sustainable bioenergy production systems.

    Cigarette smoking is a leading cause of preventable mortality worldwide. Nicotine dependence, which reduces the likelihood of quitting smoking, is a heritable trait with firmly established associations with sequence variants in nicotine acetylcholine receptor genes and at other loci. To search for additional loci, we conducted a genome-wide association study (GWAS) meta-analysis of nicotine dependence, totaling 38,602 smokers (28,677 Europeans/European Americans and 9925 African Americans) across 15 studies. In this largest-ever GWAS meta-analysis for nicotine dependence and the largest-ever cross-ancestry GWAS meta-analysis for any smoking phenotype, we reconfirmed the well-known CHRNA5-CHRNA3-CHRNB4 genes and further yielded a novel association in the DNA methyltransferase gene DNMT3B. The intronic DNMT3B rs910083-C allele (frequency=44-77%) was associated with increased risk of nicotine dependence at P=3.7 × 10(-8) (odds ratio (OR)=1.06 and 95% confidence interval (CI)=1.04-1.07 for severe vs mild dependence). The association was independently confirmed in the UK Biobank (N=48,931) using heavy vs never smoking as a proxy phenotype (P=3.6 × 10(-4), OR=1.05, and 95% CI=1.02-1.08). Rs910083-C is also associated with increased risk of squamous cell lung carcinoma in the International Lung Cancer Consortium (N=60,586, meta-analysis P=0.0095, OR=1.05, and 95% CI=1.01-1.09). Moreover, rs910083-C was implicated as a cis-methylation quantitative trait locus (QTL) variant associated with higher DNMT3B methylation in fetal brain (N=166, P=2.3 × 10(-26)) and a cis-expression QTL variant associated with higher DNMT3B expression in adult cerebellum from the Genotype-Tissue Expression project (N=103, P=3.0 × 10(-6)) and the independent Brain eQTL Almanac (N=134, P=0.028). This novel DNMT3B cis-acting QTL variant highlights the importance of genetically influenced regulation in brain on the risks of nicotine dependence, heavy smoking and consequent lung cancer

    With the total solar eclipse of 2017 August 21 over the continental United States approaching, the U.S. Naval Observatory (USNO) on-line Solar Eclipse Computer can now be accessed via an application programming interface (API). This flexible interface returns local circumstances for any solar eclipse in JavaScript Object Notation (JSON) that can be incorporated into third-party Web sites or applications. For a given year, it can also return a list of solar eclipses that can be used to build a more specific request for local circumstances. Over the course of a particular eclipse as viewed from a specific site, several events may be visible: the beginning and ending of the eclipse (first and fourth contacts), the beginning and ending of totality (second and third contacts), the moment of maximum eclipse, sunrise, or sunset. For each of these events, the USNO Solar Eclipse Computer reports the time, Sun's altitude and azimuth, and the event's position and vertex angles. The computer also reports the duration of the total phase, the duration of the eclipse, the magnitude of the eclipse, and the percent of the Sun obscured for a particular eclipse site. On-line documentation for using the API-enabled Solar Eclipse Computer, including sample calls, is available (http://aa.usno.navy.mil/data/docs/api.php). The same Web page also describes how to reach the Complete Sun and Moon Data for One Day, Phases of the Moon, Day and Night Across the Earth, and Apparent Disk of a Solar System Object services using API calls.For those who prefer using a traditional data input form, local circumstances can still be requested that way at http://aa.usno.navy.mil/data/docs/SolarEclipses.php. In addition, the 2017 August 21 Solar Eclipse Resource page (http://aa.usno.navy.mil/data/docs/Eclipse2017.php) consolidates all of the USNO resources for this event, including a Google Map view of the eclipse track designed by Her Majesty's Nautical Almanac Office (HMNAO).

    Energy sorghum (Sorghum bicolor L. Moench) could be the ideal feedstock for the cellulosic ethanol industry because of its robust establishment, broader adaptability and drought tolerance, water and nutrient use efficiency, and the relatively high annual biomass yields. Of concern, however, is the limited research data on harvest thresholds, subsequent environmental impacts and the potential cumulative effects of harvesting equipment-induced soil compaction. Indiscriminate harvests of the high volume wet energy sorghum biomass, coupled with repeated field passes, could cause irreparable damage to the soil due to compaction. Furthermore, biomass harvests result in lower soil organic matter returns to the soil, making the soil even more susceptible to soil compaction. Compacted soils result in poor root zone aeration and drainage, more losses of nitrogen from denitrification, and restricted root growth, which reduces yields. Given the many positive attributes of conservation tillage and crop residue retention, our research and extension expectations are that sustainable energy sorghum cropping systems ought to include some form of conservation tillage. The challenge is to select cropping and harvesting systems that optimize feedstock production while ensuring adequate residue biomass to sustainably maintain soil structure and productivity. Producers may have to periodically subsoil-till or plow-back their lands to alleviate problems of soil compaction and drainage, weeds, insects and disease infestations. Little, however, is known about the potential impact of these tillage changes on soil productivity, environmental integrity, and sustainability of bioenergy agro-ecosystems. Furthermore, 'safe' energy sorghum feedstock removal thresholds have yet to be established. We will apply the ALMANAC biophysical model to evaluate permissible energy sorghum feedstock harvest thresholds and the effects of subsoil tillage and periodically plowing no-tilled (NT) energy sorghum

    Deductive inference is applied to choreograph the cooperation of multiple knowledge sources to respond to geospatial queries. When no one source can provide an answer, the response may be deduced from pieces of the answer provided by many sources. Examples of sources include (1) The Alexandria Digital Library Gazetteer, a repository that gives the locations for almost six million place names, (2) The Cia World Factbook, an online almanac with basic information about more than 200 countries. (3) The SRI TerraVision 3D Terrain Visualization System, which displays a flight-simulator-like interactive display of geographic data held in a database, (4) The NASA GDACC WebGIS client for searching satellite and other geographic data available through OpenGIS Consortium (OGC) Web Map Servers, and (5) The Northern Arizona University Latitude/Longitude Distance Calculator. Queries are phrased in English and are translated into logical theorems by the Gemini Natural Language Parser. The theorems are proved by SNARK, a first-order-logic theorem prover, in the context of an axiomatic geospatial theory. The theory embodies a representational scheme that takes into account the fact that the same place may have many names, and the same name may refer to many places. SNARK has built-in procedures (RCC8 and the Allen calculus, respectively) for reasoning about spatial and temporal concepts. External knowledge sources may be consulted by SNARK as the proof is in progress, so that most knowledge need not be stored axiomatically. The Open Agent Architecture (OAA) facilitates communication between sources that may be implemented on different machines in different computer languages. An answer to the query, in the form of text or an image, is extracted from the proof. Currently, three-dimensional images are displayed by TerraVision but other displays are possible. The combined system is called Geo-Logica. Some example queries that can be handled by Geo-Logica include: (1) show the

  14. The Venus "Shell-over-Star" hieroglyph and Maya warfare: An examination of the interpretation of a Mayan symbol

    NASA Astrophysics Data System (ADS)

    Voit, Claudia Ann

    For decades, Maya scholars have associated the Mayan "Shell-Star" (also referred to as "Star-War") hieroglyph with Maya warfare. Put forward by scholars such as Floyd Lounsbury and David Kelley, and later advanced by Linda Schele, David Freidel, Ian Graham, Peter Matthews, Anthony Aveni and others, there are now dozens of published articles and chapters relating the hieroglyph to Venus and warfare. Venus is one of the most notable celestial objects outside of the Sun and Moon and was highly visible to the inhabitants of the Maya world. The Dresden Codex (an astronomical almanac) contains important information about the planet Venus, and the calendar section was deciphered by the librarian and mathematician, Ernst Förstemann in the late 1800s. In his decipherment, he deduced that the numbers contained in the tables must be connected to the orbital period of the planet. There is no other planet with the same orbital period 3 as Venus. Förstemann suggested that the decoded astronomy tables were used by the Maya to determine when to wage war. This interpretation, along with others, like Floyd Lounsbury`s study of Venus and the Long Count date at Bonampak were the seeds that have led to methodological errors that first began to take root in Maya research. The idea of the Venus association with warfare took hold and continues to propagate. Many scholars continue to assert that the "shell-star" glyph is related to warfare events. Others, like Gerardo Aldana, and Stanley Guenter, have recently come forward to reexamine and question the hieroglyph and its relationship, if any, to Maya warfare. I suggest, further, that methodological errors may have occurred along the way. I propose that these errors include data lost in translation, and inaccurate translations. In addition, the statistical analysis of Venus cycles has weak points. If this identification of the errors is correct, we need to re-evaluate the weakened foundation on which we are building our assertions about

  15. A CMIP5 Ensemble Assessment of Climate Change Impact on Durum Wheat Production in North Dakota, USA

    NASA Astrophysics Data System (ADS)

    Dillon, T. D.; Kirilenko, A.

    2016-12-01

    North Dakota is the main US and one of the world's leading producers of durum wheat (Triticum durum), the hardest wheat variety with high protein content, used in multiple food products. We investigated potential change in durum wheat production in connection with climate change. The study accounted for variations in environmental conditions by running a dynamic wheat yield model in thirteen climatically different regions of the state. North Dakota climate is representative of highly productive agricultural lands of the Northern Great Plains, which encompass five US states and two Canadian provinces. Eastern part of North Dakota has humid continental climate while the western past is semi-desert with distinct west-to east precipitation gradient. Low mean average temperatures (cir. +4C), and high temperature variability lead to relatively short growing season (cir. 130 days). Combined with limited rainfall (cir. 350 mm in the East and 560 mm in the West), it makes agriculture highly dependent on temperature and precipitation. Accordingly, climate change has high potential impact on crop production in the region. We used the ALMANAC crop growth model to simulate the production of durum wheat. Model performance was estimated by comparison of simulated yields with historical observations; and was found satisfactory (RMSE < 1.00 T/ha*yr). To account for uncertainty in projected future climate, we used an ensemble of 17 CMIP5 GCMs run under four IPCC AR5 RCP scenarios, for two time periods characteristic of the 2040s and the 2070s. GCM output data were further downscaled using MarkSim weather generator. We found statistically significant reductions in mean yields in 96% of model runs for both time periods (t-test for independent samples; p<.05). In 2040s climate, yield decrease varied from 17% for RCP 2.6 to 45% for RCP 8.5; in 2070s climate - from 35% for RCP2.6 to 73% for RCP 8.5. Further research will concentrate on crop fail risk analysis and geographical

    Background Substantial regional health inequalities have been shown to exist in Turkey for major health indicators. Turkish data on hospitals deserves a closer examination with a special emphasis on the regional differences in the context of the rapid privatization of the secondary or tertiary level health services. This study aims to evaluate the change in capacity and service delivery at public and private hospitals in Turkey between 2001-2006 and to determine the regional differences. Methods Data for this retrospective study was provided from Statistical Almanacs of Inpatient Services (2001-2006). Hospitals in each of the 81 provinces were grouped into two categories: public and private. Provinces were grouped into six regions according to a development index composed by the State Planning Organisation. The number of facilities, hospital beds, outpatient admissions, inpatient admissions (per 100 000), number of deliveries and surgical operations (per 10 000) were calculated for public and private hospitals in each province and region. Regional comparisons were based on calculation of ratios for Region 1(R1) to Region 6(R6). Results Public facilities had a fundamental role in service delivery. However, private sector grew rapidly in Turkey between 2001-2006 in capacity and service delivery. In public sector, there were 2.3 fold increase in the number of beds in R1 to R6 in 2001. This ratio was 69.9 fold for private sector. The substantial regional inequalities in public and private sector decreased for the private sector enormously while a little decrease was observed for the public sector. In 2001 in R1, big surgical operations were performed six times more than R6 at the public sector whereas the difference was 117.7 fold for the same operations in the same regions for the private sector. These ratios decreased to 3.6 for the public sector and 13.9 for the private sector in 2006. Conclusions The private health sector has grown enormously between 2001-2006 in

    In the Kazan University computer simulation is carried out for observation of lunar physical libration in projects planned installation of measuring equipment on the lunar surface. One such project is the project of ILOM (Japan), in which on the lunar pole an optical telescope with CCD will be equipped. As a result, the determining the selenographic coordinates (x and y) of a star with an accuracy of 1 ms of arc will be achieved. On the basis of the analytical theory of physical libration we developed a technique for solving the inverse problem of the libration. And we have already shown, for example, that the error in determining selenographic coordinates about ɛ seconds does not lead to errors in the determination of the libration angles ρ and Iσ larger than the 1.414ɛ. Libration in longitude is not determined from observations of the polar star (Petrova et al., 2012). The accuracy of the libration in the inverse problem depends on accuracy of the coordinates of the stars - α and δ - taken from the star catalogs. Checking this influence is the task of the present study. To do simulation we have developed that allows to choose the stars, falling in the field of view of the lunar telescope on observation period. Equatorial coordinates of stars were chosen by us from several fundamental catalogs: UCAC2-BSS, Hipparcos, Tycho, FK6 (part I, III) and the Astronomical Almanac. An analysis of these catalogues from the point of view accuracy of coordinates of stars represented in them was performed by Nefediev et al., 2013. The largest error, 20-70 ms, found in the catalogues UCAC2 and Tycho, the others have an error about a millisecond of arc. We simulated the observations with mentioned errors and got the following results. 1. The error in the declination Δδ of the star causes the same order error in libration parameters ρ and Iσ , while the sensitivity of libration to errors in Δα is ten time smaller. Fortunately, due to statistics (30 to 70, depending on

    In 1879 Benjamin Apthorp Gould published in Buenos Aires, Argentina, the Uranometria Argentina catalog of 7756 stars south of declination +10 degrees. This included all those stars he considered magnitude 7 or brighter and some fainter stars which are close companions to brighter stars or to each other and have combined magnitude 7 or brighter. Star positions are in 1875 coordinates, and constellation boundaries also in 1875 coordinates were defined within the aforementioned declination range. With only a few small changes these were incorporated into the boundaries adopted by the IAU in 1930 and subsequently universally accepted. In terms of accurate photoelectric magnitude measurements the Uranometria Argentina is nearly complete to magnitude 6.5 in its declination range. In each constellation the individual stars considered to be magnitude 7 and brighter were numbered in sequence of increasing right ascension in 1875 coordinates, except that in a few cases this sequence was somewhat adjusted so that stars close together could be listed on adjacent lines of text. The numbering system is analogous to that in the Flamsteed Catalogus Brittanicus and now widely used. Star numbers from the Uranometria Argentina rarely appear in the 21st century despite the potential utility of their use. They were included in the American Ephemeris and Nautical Almanac until 1978, and in the FK5 catalog until 1999, always with the letter G following the number in the Uranometria Argentina catalog. This serves to distinguish Flamsteed numbers with no following letters from Gould numbers, and is utilized in this presentation and recommended for general use. The file catalog.dat includes every star in the original Uranometria Argentina. In the original the constellations were presented in sequence of increasing distance from the south pole and numbered accordingly. For the convenience of 21st century astronomers the constellations are presented here by alphabetical sequence in

    Transits of Venus, in which the planet Venus crosses the face of the Sun as seen from Earth, are rare phenomena that occur at intervals of 105.5 years, 8 years, 121.5 years, and 8 years, respectively. Two such transits occurred in the 19th century, in 1874 and 1882. The importance of these transits was that by precisely timing the motion of Venus accross the Sun, they provided a method of determining the solar parallax, and thus Earth-Sun distance and the scale of the solar system, one of the great unsolved problems in the history of astronomy at the time. In a broader sense the worldwide efforts to observe this phenomenon are important because of the debate over photographic techniques, and because they are part of the overall history of the determination of the astronomical constants. Eight American expeditions were fitted out in 1874, organized by the Transit of Venus Commission, with Simon Newcomb as Secretary. The U. S. Congress appropriated funds totalling an astounding \\177,000 for the expeditions. Although Newcomb considered the result of the 1874 observations disappointing due to inherent difficulties in the method, at the urging of Naval Observatory astronomer William Harkness, in 1882 Congress once again appropriated some \\10,000 for improving the instruments, and \\$75,000 for sending eight more expeditions. Despite reservations about the method, Newcomb (now Superintendent of the Nautical Almanac Office) led an expedition to South Africa, and among the four northern stations, Asaph Hall led the expedition to San Antonio, Texas. The value of the observations made by the 1882 American expeditions also caused considerable dispute. Newcomb's statement in his Reminiscences (1903) that the 1882 results were never officially published has been taken to mean that no results were ever produced. In fact Harkness spent a considerable part of his career analyzing the data, producing a value for the solar parallax, and putting it in context of other astronomical

    initio within the relativistic framework presented in the other resolutions (in that regard, there still exist some difficult problems to solve), their relativistic terms are accurate enough for all the current and near-future observational techniques. At that level, the Earth rotation models are consistent with the general relativity framework recommended by the IAU and considered in this book. The chapter presents practical algorithms for implementing the recommended models. The appendices to the book contain a list of astronomical constants and the original text of the relevant IAU resolutions adopted by the IAU General Assemblies in 1997, 2000, 2006, and 2009.

    Georgetown University studying astronomy. On July 6, 1963, Tom Van Flandern married Barbara Ann Weber in Kentucky. They remained together until his passing 46 years later. They had four children, Michael, Constance, Brian, and Kevin. Also in 1963, Tom began work in the Nautical Almanac Office of the U.S. Naval Observatory in Washington, DC. He became an expert on refining the lunar orbit from timings of lunar occultations, then the best observations for that purpose. He encouraged observations by providing observers with predictions of occultations for their locations. He designed a cable system connecting all observers timing a grazing occultation, to record their observations at a central station. After a 1964 success, four amateur astronomical societies built similar cable systems. Tom Van Flandern relished efforts to simplify computer calculations. He and Henry Fliegel developed an algorithm to calculate a Julian date from a Gregorian date that would fit on a single IBM card. They published this in a paper, "A machine algorithm for processing calendar dates" in 1968 in the Communications of the Association for Computing Machinery. This was used in countless business applications worldwide. With Kenneth Pulkkinen, he published "Low precision formulae for planetary positions", in Ap. J. Supp. in 1979. The paper set a record for the number of reprints requested from that journal. Tom Van Flandern earned a PhD in astronomy from Yale University in 1969. His thesis was "A discussion of 1950-1968 occultations of stars by the Moon," advised by Prof. G. M. Clemence. In 1976 Van Flandern asserted that the orbits of 60 long-period comets traced to a common origin, supporting Michael Ovenden's exploded planet hypothesis. He founded the non-profit Meta Research, Inc. in 1990 to provide support for alternative theories in astronomy. The Meta Research Bulletin reported the newest discoveries and how they presented difficulties to accepted astronomical theories, such as the Big Bang and

    Brian Geoffrey Marsden was born on 1937 August 5 in Cambridge, England. His father, Thomas, was the senior mathematics teacher at a local high school. It was his mother, Eileen (nee West), however, who introduced him to the study of astronomy, when he returned home on the Thursday during his first week in primary school in 1942 and found her sitting in the back yard watching an eclipse of the sun. Using now frowned-upon candle-smoked glass, they sat watching the changing bite out of the sun. What most impressed the budding astronomer, however, was not that the eclipse could be seen, but the fact that it had been predicted in advance, and it was the idea that one could make successful predictions of events in the sky that eventually led him to his career. When, at the age of 11, he entered the Perse School in Cambridge he was developing primitive methods for calculating the positions of the planets. He soon realized that earlier astronomers had come up with more accurate procedures for doing this over the centuries, and during the next couple of years this led to his introduction to the library of the Cambridge University Observatories and his study of how eclipses, for example, could be precisely computed. Together with a couple of other students he formed a school Astronomical Society, of which he served as the secretary. At the age of 16 he joined and began regularly attending the monthly London meetings of the British Astronomical Association. He quickly became involved with the Association's Computing Section, which was known specifically for making astronomical predictions other than those that were routinely being prepared by professional astronomers for publication in almanacs around the world. Under the watchful eyes of the director and assistant director of the Computing Section, this led him to prepare and publish predictions of the occasions when one of Jupiter's moons could be seen to pass directly in front of another. He also calculated the
