    Human immunodeficiency virus (HIV) researchers often use calendar periods as an imperfect proxy for highly active antiretroviral therapy (HAART) when estimating the effect of HAART on HIV disease progression. The authors report on 614 HIV-positive homosexual men followed from 1984 to 2007 in 4 US cities. During 5,321 person-years, 268 of 614 men incurred acquired immunodeficiency syndrome, 49 died, and 90 were lost to follow-up. Comparing the pre-HAART calendar period (<1996) with the HAART calendar period (≥1996) resulted in a naive rate ratio of 3.62 (95% confidence limits: 2.67, 4.92). However, this estimate is likely biased because of misclassification of HAART use by calendar period. Simple calendar period approaches may circumvent confounding by indication at the cost of inducing exposure misclassification. To correct this misclassification, the authors propose an instrumental-variable estimator analogous to ones previously used for noncompliance corrections in randomized clinical trials. When the pre-HAART calendar period was compared with the HAART calendar period, the instrumental-variable rate ratio was 5.02 (95% confidence limits: 3.45, 7.31), 39% higher than the naive result. Weighting by the inverse probability of calendar period given age at seroconversion, race/ethnicity, and time since seroconversion did not appreciably alter the results. These methods may help resolve discrepancies between observational and randomized evidence. PMID:19318615

    The relationship between Mayan and our calendar is expressed by a coefficient known as `correlation' which is a number of days that we have to add to the Mayan Long Count date to get Julian Date used in astronomy. There is a surprisingly large uncertainty in the value of the correlation, yielding a shift between both calendars (and thus between the history of Maya and of our world) of typically several hundred years. There are more than 50 diverse values of the correlation, some of them derived from historical, other by astronomical data. We test here (among others) the well established Goodman-Martínez-Thompson correlation (GMT) based on historical data, and the Böhms' one (B&B) based on astronomical data decoded from the Dresden Codex (DC); this correlation differs by about +104 years from the GMT. In our previous works we used several astronomical phenomena as recorded in the DC for a check. We clearly demonstrated that (i) the GMT was not capable to predict these phenomena that really happened in nature and (ii) that the GMT predicts them on the days when they did not occur. The phenomena used till now in the test are, however, short-periodic and the test then may suffer from ambiguity. Therefore, we add long-periodic astronomical phenomena, decoded successfully from the DC, to the testing. These are (i) a synchrony of Venusian heliacal risings with the solar eclipses, (ii) a synchrony of Venus and Mars conjunctions with eclipses, (iii) conjunctions of Jupiter and Saturn repeated in a rare way, and (iv) a synchrony of synodic and sideric periods of Mercury with the tropical year. Based on our analysis, we find that the B&B correlation yields the best agreement with the astronomical phenomena observed by the Maya. Therefore, we recommend to reject the GMT and support the B&B correlation.

    Our aim is to evaluate the relevance of different factors influencing lifetime accumulated red bone marrow dose, such as calendar year, age and sex. The lifetime dose was estimated for controls interviewed in person (N = 2811, 37.5% women) of the population-based representative Northern Germany Leukemia and Lymphoma Study. Data were assessed in standardized computer-assisted personal interviews. The calculation of doses is based on a comprehensive quantification model including calendar year, sex, kind of examination, and technical development. In multivariate regression models the annual red bone marrow dose was analyzed depending on age, sex and calendar year to consider simultaneously temporal changes in radiologic practice and individual risk factors. While the number of examinations continuously rises over time, the dose shows two peaks around 1950 and after 1980. Men are exposed to higher doses than woman. Until 1970 traditional examinations like conventional and mass screening examinations caused the main dose. They were then replaced by technically advanced examinations mainly computed tomography and cardiac catheter. The distribution of the red bone marrow dose over lifetime depends highly on the technical standards and radiation protection survey. To a lesser extent it is influenced by age and sex of the subjects. Thus epidemiological studies concerning the assessment of radiation exposure should consider the calendar year in which the examination was conducted. PMID:24244286

    The present study aims at establishing a methodology for a comprehensive calendar ageing predictive model development, focusing specially on validation procedures. A LFP-based Li-ion cell performance degradation was analysed under different temperature and SOC storage conditions. Five static calendar ageing conditions were used for understanding the ageing trends and modelling the dominant ageing phenomena (SEI growth and the resulting loss of active lithium). The validation process included an additional test under other constant operating conditions (static validation) and other four tests under non-constant impact factors operating schemes within the same experiment (dynamic validation), in response to battery stress conditions in real applications. Model predictions are in good agreement with experimental results as the residuals are always below 1% for experiments run for 300-650 days. The model is able to predict dynamic behaviour close to real operating conditions and the level of accuracy corresponds to a root-mean-square error of 0.93%.

    Stern, Sacha

    This chapter surveys the history of Jewish calendars from Biblical origins to the later Middle Ages, with reference to their structure, astronomical basis, and cultural context. Special attention is given to the 364-day calendar (third century BCE-first century CE) and the fixed rabbinic calendar (from late Antiquity to the Middle Ages). The chapter concludes with a discussion of attempts to date the institution of the rabbinic calendar on the basis of its minor astronomical discrepancies.

    In 2001, in the northeast part of Macedonia, a site of impressive dimensions and with remarkable contents was discovered. Archaeological excavations in the following years have shown that the site represents a huge mountain sanctuary with enormous amount of artefact dated in XIX century B.C. In unison, performed archaeo-astronomical analysis exposed the fact that this site encompasses all characteristics of an ancient observatory built 3900 years ago as a result of which the site was called Megalithic Observatory Kokino. As any similar observatory, Megalithic Observatory Kokino was used for development of a calendar, by utilization of which, life in the community of ancient farmers was organized. By the end of 2006 and at the beginning of 2007, specially crafted stone markers for measurement of lunar month were discovered. This fact revealed that people of that time living in the area of Central Balkan Peninsula were familiar with the 19 years lunar cycle, according to which they prepared lunar calendar, today known as Kokino Calendar. In the course of 2007, additional evidences found verified that on the territory of the ancient observatory there is a specially crafted observation post and four stone markers used for observation of the Full Moon rise on the east horizon in the night of its total eclipse. These stone markers marked the cycles of eclipses in periods of 54 years and 34 days.

  10. Age-associated circadian period changes in Arabidopsis leaves

    As most organisms age, their appearance, physiology, and behaviour alters as part of a life history strategy that maximizes their fitness over their lifetime. The passage of time is measured by organisms and is used to modulate these age-related changes. Organisms have an endogenous time measurement system called the circadian clock. This endogenous clock regulates many physiological responses throughout the life history of organisms to enhance their fitness. However, little is known about the relation between ageing and the circadian clock in plants. Here, we investigate the association of leaf ageing with circadian rhythm changes to better understand the regulation of life-history strategy in Arabidopsis. The circadian periods of clock output genes were approximately 1h shorter in older leaves than younger leaves. The periods of the core clock genes were also consistently shorter in older leaves, indicating an effect of ageing on regulation of the circadian period. Shortening of the circadian period with leaf age occurred faster in plants grown under a long photoperiod compared with a short photoperiod. We screened for a regulatory gene that links ageing and the circadian clock among multiple clock gene mutants. Only mutants for the clock oscillator TOC1 did not show a shortened circadian period during leaf ageing, suggesting that TOC1 may link age to changes in the circadian clock period. Our findings suggest that age-related information is incorporated into the regulation of the circadian period and that TOC1 is necessary for this integrative process. PMID:27012281

    The ``Madonna di Loreto'' (Trinitapoli, Puglia) site is the largest Bronze Age sanctuary presently known in Italy. Inside its area, several hypogeal structures excavated in the calcareous rock and devoted to ritual use were found. The most impressive manifestation of the cult is however a set of more than 1000 circular holes, aligned in rows and covering the whole sacred area. The holes were excavated during many centuries, following a rigid plan and taking into account specific celestial points. The archaeoastronomical study of the rows revealed three main alignments: that with the highest frequency, i.e. with the highest number of holes, is along the meridian, thus referring to astronomical phenomena with a daily periodicity; that with an intermediate frequency to a phenomenon with annual periodicity (the azimuth of the sunrise on a peculiar day, near to the summer solstice), and that with the lowest frequency to the South major lunistice, a phenomenon with a long term (18.6 years) periodicity. This agreement has a very high statistical significance and it allows us to interpret the hole rows as elements of a complex calendric system with a ritual character.

    Longitudinal analysis investigates period (P), often as years. Additional scales of time are age (A) and birth cohort (C) Aim of our study was to use ecological APC analysis for women breast cancer incidence and mortality in Germany. Nation-wide new cases and deaths were obtained from Robert Koch Institute and female population from federal statistics, 1999–2008. Data was stratified into ten 5-years age-groups starting 20–24 years, ten birth cohorts starting 1939–43, and two calendar periods 1999–2003 and 2004–2008. Annual incidence and mortality were calculated: cases to 100,000 women per year. Data was analyzed using glm and apc packages of R. Breast cancer incidence and mortality increased with age. Secular rise in breast cancer incidence and decline in mortality was observed for period1999-2008. Breast cancer incidence and mortality declined with cohorts; cohorts 1950s showed highest incidence and mortality. Age-cohort best explained incidence and mortality followed by age-period-cohort with overall declining trends. Declining age-cohort mortality could be probable. Declining age-cohort incidence would require future biological explanations or rendered statistical artefact. Cohorts 1949–1958 could be unique in having highest incidence and mortality in recent time or future period associations could emerge relatively stronger to cohort to provide additional explanation of temporal change over cohorts.

    OBJECTIVE To investigate age-period-cohort effects on the temporal trend of type 1 diabetes in children age 0–14 years in Italian registries. RESEARCH DESIGN AND METHODS This report is based on 5,180 incident cases in the period 1990–2003 from the Registry for Type 1 Diabetes Mellitus in Italy (RIDI). Multilevel (random intercept) Poisson regression models were used to model the effects of sex, age, calendar time, and birth cohorts on temporal trends, taking into account the registry-level variance component. RESULTS The incidence rate was 12.26 per 100,000 person-years and significantly higher in boys (13.13 [95% CI 12.66–13.62]) than in girls (11.35 [10.90–11.82]). Large geographical variations in incidence within Italy were evident; incidence was highest in Sardinia, intermediate in Central-Southern Italy, and high in Northern Italy, particularly in the Trento Province, where the incidence rate was 18.67 per 100,000 person-years. An increasing temporal trend was evident (2.94% per year [95% CI 2.22–3.67]). With respect to the calendar period 1990–1992, the incidence rates increased linearly by 15, 27, 35, and 40% in the following time periods (P for trend < 0.001). With respect to the 1987–1993 birth cohort, the incidence rate ratio increased approximately linearly from 0.63 (95% CI 0.54–0.73) in the 1975–1981 cohort to 1.38 (1.06–1.80) in the 1999–2003 cohort. The best model, however, included sex, age, and a linear time trend (drift). CONCLUSIONS Large geographical variations and an increasing temporal trend in diabetes incidence are evident among type 1 diabetic children in Italy. Age-period-cohort analysis shows that the variation over time has a linear component that cannot be ascribed to either the calendar period or the birth cohort. PMID:20566665

  15. Wooden Calendars from Central Rhodopes

    Four wooden calendars from the village of Polkovnik Serafimovo, Smolyan region, in the Central Rhodopes are presented here, and three of them - for the first time. The shape and size, the kind of the signs and structure of the calendar record bear the characteristic features of the rest of the Bulgarian wooden calendars. The short notches on the edges represent the days of the year in the Julian (solar) calendar. The special signs on the sides mark the fixed festivals of the Orthodox Church calendar and are also influenced by the local tradition. The type of the signs confirms that the wooden sticks belong to the group of calendars from the Central Rhodopes. According to the beginning date of the calendar record on the sticks, two of the calendars are of the April (May) or October (November) type which corresponds to the very popular economic division of the year in the folk calendar into two periods -- warm and cold. The other two sticks, which are very similar to each other, make an exception in this respect among the rest of the Bulgarian wooden calendars. The months are divided into four groups (seasons) on each of the four edges of the stick (only one calendar from Burgas region has the same structure). The most interesting thing about the two sticks is that this is the only case among all known Bulgarian calendars that the beginning of the calendar record coincides with the beginning of the civil year on 1st January (January type) like some wooden calendars from Western Europe. Nowadays it is getting harder and harder to find wooden calendars in Bulgaria and in the neighbouring Balkan countries. The thorough knowledge about them could be helpful in various scientific fields, e.g. history of religion, ethnology, history of astronomy and mathematics, as well as semiotics.

    The study of the Egyptian calendar lends itself to a deeper analysis in which the original system of calendrics was based on the moon and the later one, organized by a simple device of 365 days per year. The latter, originally determined by the sighting of the star Sothis (Sirius) in the east after a period of 70 days of invisibility, is called the Civil Calendar. The change, however, brought with it an alteration in the names of the Egyptian months.

    Ziółkowski, Mariusz

    The ritual, central Inca calendar, adapted to the ecological, cultural, and ethnic realities of the Cuzco valley, was the basis of the imperial calendar, used for the administration of the Inca Empire. According to the main historical sources, it was composed of 12 synodic months calculated from new moon to new moon. The correlation of this cycle with the tropical year was achieved by the intercalation of an additional 13th month, every 2 or 3 years. Tom Zuidema's thesis about the existence of the "stellar lunar calendar" or "quipu-calendar" is also analyzed.

    2005-07-01

    The aging dynamics under a periodic shear of a concentrated suspension of saponite particles is measured. It is observed that the dynamics is fastened by the application of a moderate shear amplitude. Nevertheless, this acceleration does not affect the dynamics of the suspension when the shear is ceased. By applying a succession of shear of various amplitudes, we conclude that the dynamics of the suspension at a time t(w) after complete rejuvenation is independent of the shear history between times 0 and t(w) , as soon as the amplitude of the applied shear is smaller than the characteristic shear gamma(c) necessary to completely rejuvenate the suspension.

  5. Wooden Calendar Sticks in Eastern Europe

    NASA Astrophysics Data System (ADS)

    Koleva, Vesselina; Koleva, Svetlana

    Wooden calendar sticks have preserved an archaic time-keeping tradition, which, during the Middle Ages, was one of the tools for establishing and disseminating Christian chronology and the liturgical calendars of the Western and Eastern Churches. The calendars vary in size and shape, type of signs, and structure of the record. Christian symbols interwoven with signs and pictograms mark days of importance in the ritual and economic year cycle. The wooden calendars are considered one of the proofs of the syncretism between the pagan tradition and Christian rites in folk cultures.

  6. EVIDENCE IN CRATER AGES FOR PERIODIC IMPACTS ON THE EARTH

    Alvarez, W.; Muller, R.A.

    1984-01-01

    Recent evidence has indicated that the impact of a comet or asteroid may have been responsible for mass extinction at the ends of both the Cretaceous and the Eocene. Quantitative analysis by Raup and Sepkoski showed that mass extinctions occur with a 26-Myr period, similar to the period seen in qualitative pelagic records by Fischer and Arthur. To account for the possibility of periodic comet showers, Davis et al. proposed that such showers could be triggered by an unseen solar companion star as it passes through perihelion on a moderately eccentric orbit. To test a prediction implicit in this model we examined records of large impact craters on the Earth. We report here that most of the craters occur in a 28.4-Myr cycle. Within measurement errors, this period and its phase are the same as those found in the fossil mass extinctions. The probability that such agreement is accidental is 1 in 10.

    Getashen hydria was found in the tombs of the middle bronze age (the first third of the second Millennium B.C.) in Armenia (Lake Sevan). It shows a scene consisting of three friezes. On the lower frieze depicts six zoomorphic figures, on an average six frieze waterfowl, and on top, is the graphic signs. Calendar motives of this composition have a numeric expression, six zoomorphic figures on the lower and middle friezes. Division of the annual cycle into two parts is known in the calendars of the ancient Indo-Iranian ("great summer" and "the great winter"). Animals on the lower frieze of the second mark, "winter" road of the Sun, because in this period are the most important events, ensuring the reproduction of the economy of the society. This rut ungulates - wild (deer) and domestic (goats). Moreover, the gon goats end in December, almost coinciding with the onset of the winter solstice. A couple of dogs on the lower frieze marks the version of the myth, imprisoned in the rock hero - the Sun (Mihr - Artavazd), to which his dogs have to chew the chains, anticipating his exit at the winter solstice. This is indicated by the direction of their movement, the Sun moves from left to right for an observer, only when located on the South side of the sky (i.e., beginning with the autumnal equinox). The most important event of the period of "summer road" of the Sun is the vernal equinox, which coincide with the arrival of waterfowl (ducks, geese). Their direction on the second frieze (left to right) corresponds to the position of the observer, facing North.

  8. Korean Astronomical Calendar, Chiljeongsan

    NASA Astrophysics Data System (ADS)

    Lee, Eun Hee

    In fifteenth century Korea, there was a grand project for the astronomical calendar and instrument making by the order of King Sejong 世宗 (1418-1450). During this period, many astronomical and calendrical books including Islamic sources in Chinese versions were imported from Ming 明 China, and corrected and researched by the court astronomers of Joseon 朝鮮 (1392-1910). Moreover, the astronomers and technicians of Korea frequently visited China to study astronomy and instrument making, and they brought back useful information in the form of new published books or specifications of instruments. As a result, a royal observatory equipped with 15 types of instrument was completed in 1438. Two types of calendar, Chiljeongsan Naepyeon 七政算內篇 and Chiljeongsan Oepyeon 七政算外篇, based on the Chinese and Islamic calendar systems, respectively, were published in 1444 with a number of calendrical editions such as corrections and example supplements (假令) including calculation methods and results for solar and lunar eclipses.

    One hundred seven commercially available, off-the-shelf, 1.2-Ah cells were tested for calendar life and CS cycle- and CD cycle-life using the new USABC PHEV Battery Test Manual. Here, the effects of temperature on calendar life, on CS cycle life, and on CD cycle life; the effects of SOC on calendar life and on CS cycle life; and the effects of rest time on CD cycle life were investigated. The results indicated that the test procedures caused performance decline in the cells in an expected manner, calendar < CS cycling < CD cycling. In some cases, the kinetic law changed with test type, from linear-with-time to about t2. Additionally, temperature was found to stress the cells more than SOC, causing increased changes in performance with increasing temperature.

    One of the most difficult properties to derive for stars is their age. For cool main-sequence stars, gyrochronology relations can be used to infer stellar ages from measured rotation periods and Hertzsprung Russell diagram positions. These relations have few calibrators with known ages for old, long rotation period stars. There is a significant sample of old Kepler objects of interest, or KOIs, which have both measurable surface rotation periods and precise asteroseismic measurements from which ages can be accurately derived. In this work, we determine the age and the rotation period of solar-like pulsating KOIs to both compare the rotation properties of stars with and without known planets and enlarge the gyrochronology calibration sample for old stars. We use Kepler photometric light curves to derive the stellar surface rotation periods while ages are obtained with asteroseismology using the Asteroseismic Modelling Portal in which individual mode frequencies are combined with high-resolution spectroscopic parameters. We thus determine surface rotation periods and ages for 11 planet-hosting stars, all over 2 Gyr old. We find that the planet-hosting stars exhibit a rotational behaviour that is consistent with the latest age-rotation models and similar to the rotational behaviour of stars without detected planets. We conclude that these old KOIs can be used to test and calibrate gyrochronology along with stars not known to host planets.

    Aging of lithium-ion cells is an inevitable phenomenon limiting the lifetime. Undesirable side reactions during cycle or calendar aging may affect the performance of all components of the lithium-ion cell. This results in a decreased capacity and an increase in the overall cell impedance. Based on electrochemical and physical characterization methods, the aging behavior during calendar aging of a 18650-cell, containing a blend of LiMn2O4 and Li(Ni1/3Mn1/3Co1/3)O2 (NMC) as cathode material and graphite as anode material was systematically investigated. To understand how the safety behavior of a lithium-ion cell changes with aging, accelerating rate calorimetry (ARC) and differential scanning calorimetry (DSC) were applied. With these methods the thermal stability behavior of the complete lithium-ion cell and its respective cathode and anode material were investigated. The focus of this work was it to generate first cause-effect relations between the aging under one exemplary aging condition and the thermal stability of a lithium-ion battery both on cell and material level.

    This study focused on age-related changes in visual short-term memory using visual stimuli that did not allow verbal encoding. Experiment 1 examined the effects of age and the length of the stimulus presentation period on visual short-term memory function. Experiment 2 examined the effects of age, gender, and the length of the stimulus presentation period on visual short-term memory function. The worst memory performance and the largest performance difference between the age groups were observed in the shortest stimulus presentation period conditions. The performance difference between the age groups became smaller as the stimulus presentation period became longer; however, it did not completely disappear. Although gender did not have a significant effect on d' regardless of the presentation period in the young group, a significant gender-based difference was observed for stimulus presentation periods of 500 ms and 1,000 ms in the older group. This study indicates that the decline in visual short-term memory observed in the older group is due to the interaction of several factors. PMID:26745456

    A number of mentally handicapped individuals are able to solve difficult calendar date problems such as specifying the day of the week for a particular date, sometimes over spans of more than 100 years. These individuals are self-taught and do not follow procedures at all similar to the usual, published, algorithms. An investigation of one individual revealed that he retained considerable information about the structure of days in particular months, probably as visual images. His skill closely depended on the extent and form of his knowledge of calendars, and his errors were often a consequence of lack of knowledge about a particular time period. Mentally retarded individuals who perform calendar-date feats are often socially withdrawn and devote considerable periods of time to calendar dates. The most capable calendar-date calculators are usually individuals who have a strong interest in calendars as such. PMID:3167499

    Axonal transport is critical for supplying newly synthesized proteins, organelles, mRNAs, and other cargoes from neuronal cell bodies into axons. Its impairment in many neurodegenerative conditions appears likely to contribute to pathogenesis. Axonal transport also declines during normal aging, but little is known about the timing of these changes, or about the effect of aging on specific cargoes in individual axons. This is important for understanding mechanisms of age-related axon loss and age-related axonal disorders. Here we use fluorescence live imaging of peripheral nerve and central nervous system tissue explants to investigate vesicular and mitochondrial axonal transport. Interestingly, we identify 2 distinct periods of change, 1 period during young adulthood and the other in old age, separated by a relatively stable plateau during most of adult life. We also find that after tibial nerve regeneration, even in old animals, neurons are able to support higher transport rates of each cargo for a prolonged period. Thus, the age-related decline in axonal transport is not an inevitable consequence of either aging neurons or an aging systemic milieu. PMID:25443288

  20. Ancient Greek Calendars

    NASA Astrophysics Data System (ADS)

    Hannah, Robert

    Greek festival calendars were in origin lunar, eventually being aligned with the sun through various lunisolar intercalary cycles. Each city-state had its own calendar, whose month names have some, little, or no similarity with those of other city-states. These names often reflect gods or festivals held in their honor in a given month, so there is an explicitly sacred character to the calendar. New Year's Day could also differ from one state to another, but generally began with the sighting of the first new moon after one of the four tropical points. Even the introduction of the Roman Julian calendar brought little uniformity to the eastern Greek calendars. The calendar is one of the elements which can assist in understanding the siting of Greek sacred structures.

    Amyotrophic lateral sclerosis (ALS) is a disease of the motor neuron with poorly understood etiology. Recent studies have suggested that the incidence rate of ALS and the rate of death from ALS are increasing, but it is unclear whether this is due to changing exposures or improvements in diagnosis. We used age-period-cohort models to investigate trends in ALS incidence (hospitalization) from 1982 to 2009 and ALS mortality from 1970 to 2009 in Denmark. Among those 45 years of age or older, 4,265 deaths (incidence rate = 5.35 per 100,000 person-years) and 3,228 incident diagnoses (incidence rate = 5.55 per 100,000 person-years) were recorded. Age-adjusted mortality rates increased by an average of 3.0% annually between 1970 and 2009 and by an average of 2.1% annually after 1982. Age-period-cohort analyses suggested that the full age-period-cohort model provided the best fit to the mortality data (P < 0.001), although restriction to the post-1982 period suggested that the age-cohort model provided the best fit. Age-adjusted incidence rates increased by 1.6% annually after 1982 (P < 0.001), which was best explained by the age-period model, with borderline significant cohort effects (P = 0.08). A consistent finding regardless of parameterization or data subset appeared to be an increase in ALS incidence and mortality rate with later birth cohorts, up to a birth year of at least 1910.

    A new sample of solar analogs and twin candidates has been constructed and studied, paying particular attention to their light curves from NASA's Kepler mission. This Letter aims to assess their evolutionary status, derive their rotation and ages, and identify those which are solar analogs or solar twin candidates. We separate out the subgiants that compose a large fraction of the asteroseismic sample, and which show an increase in the average rotation period as the stars ascend the subgiant branch. The rotation periods of the dwarfs, ranging from 6 to 30 days and averaging 19 days, allow us to assess their individual evolutionary states on the main sequence and to derive their ages using gyrochronology. These ages are found to be in agreement with a correlation coefficient of r = 0.79 with independent asteroseismic ages, where available. As a result of this investigation, we are able to identify 34 stars as solar analogs and 22 of them as solar twin candidates.

    There is increasing evidence that aging is affected by biological (circadian) clocks - the internal mechanisms that coordinate daily changes in gene expression, physiological functions and behavior with external day/night cycles. Recent data suggest that disruption of the mammalian circadian clock results in accelerated aging and increased age-related pathologies such as cancer; however, the links between loss of daily rhythms and aging are not understood. We sought to determine whether disruption of the circadian clock affects lifespan and healthspan in the model organism Drosophila melanogaster. We examined effects of a null mutation in the circadian clock gene period (per01) on the fly healthspan by challenging aging flies with short-term oxidative stress (24h hyperoxia) and investigating their response in terms of mortality hazard, levels of oxidative damage, and functional senescence. Exposure to 24h hyperoxia during middle age significantly shortened the life expectancy in per01 but not in control flies. This homeostatic challenge also led to significantly higher accumulation of oxidative damage in per01 flies compared to controls. In addition, aging per01 flies showed accelerated functional decline, such as lower climbing ability and increased neuronal degeneration compared to age-matched controls. Together, these data suggest that impaired stress defense pathways may contribute to accelerated aging in the per mutant. In addition, we show that the expression of per gene declines in old wild type flies, suggesting that the circadian regulatory network becomes impaired with age. PMID:20157575

    The purpose of this study was to develop a complex exercise program integrating Eastern and Western complex exercise rehabilitation programs in order to examine the effects of it on the human body with the subjects for women of the II period of mature age with metabolic syndrome. The subjects of this study are 60 II period of mature aged women with metabolic syndrome living in G City, and the experimental group conducted Taekwon-aerobic exercise, European rehabilitation gymnastics, gym ball exercise, and elastic band exercise while the control group performed European rehabilitation gymnastics, gym ball exercise, and elastic band exercise which is the rehabilitation program being presently conducted in Russia, for 90 min per day for three weeks. Two-way ANOVA with repeated measures was utilized to verify pre and post-intergroup difference, and the significant level was set as P< 0.05. Whereas body weight, % fat, WHR, SBP, DBP and blood glucose were significant decreased, muscle weight and pulse wave velocity were significant increased after complex exercise rehabilitation programs Both Eastern and Western complex exercise rehabilitation programs showed positive effects on the body of the II period of mature aged women with metabolic syndrome, and if various exercise programs are conducted, it will be more effective in improving II period of mature aged women’s metabolic syndrome afterwards.

    The objective of our study was to evaluate the combined effects of ageing period and different freezing rates on meat quality attributes of beef loins. Pairs of loins (M. longissimus at 1 day post mortem) from 12 carcasses were divided into four equal portions and randomly assigned to four ageing/freezing treatments (aged only, frozen only, and 3 or 4 weeks ageing at -1.5°C then frozen). Two freezing methods (fast freezing by calcium chloride immersion or slow freezing by air freezer at -18°C) were applied to the loin sections. Fast freezing had no effect on shear force (P>0.05), but significantly improved the water-holding capacity of the aged/frozen loins by reducing purge and drip losses. Ageing-then-freezing significantly improved shear force values of loins compared to both the aged only and frozen only loins. These observations suggest that fast freezing will add more value to the aged/frozen/thawed meat by minimising the amount of water-loss due to the freezing/thawing process. PMID:26172242

    This research examined the development of materialism across the life span. Two initial studies revealed that (a) lay beliefs were that materialism declines with age and (b) previous research findings also implied a modest, negative relationship between age and materialism. Yet, previous research has considered age only as a linear control variable, thereby precluding the possibility of more intricate relationships between age and materialism. Moreover, prior studies have relied on cross-sectional data and thus confound age and cohort effects. To improve on this, the main study used longitudinal data from 8 waves spanning 9 years of over 4,200 individuals (16 to 90 years) to examine age effects on materialism while controlling for cohort and period effects. Using a multivariate multilevel latent growth model, it found that materialism followed a curvilinear trajectory across the life span, with the lowest levels at middle age and higher levels before and after that. Thus, in contrast to lay beliefs, materialism increased in older age. Moreover, age effects on materialism differed markedly between 3 core themes of materialism: acquisition centrality, possession-defined success, and acquisition as the pursuit of happiness. In particular, acquisition centrality and possession-defined success were higher at younger and older age. Independent of these age effects, older birth cohorts were oriented more toward possession-defined success, whereas younger birth cohorts were oriented more toward acquisition centrality. The economic downturn since 2008 led to a decrease in acquisition as the pursuit of happiness and in desires for personal growth, but to an increase in desires for achievement.

    We compile a unique 13-year record of groundwater age for 11 springs in Sagehen basin, a watershed in the Sierra Nevada Mountains of California, USA. Chlorofluorocarbon (CFC), sulfur hexafluoride (SF6), and tritium (3H) data collected in prior studies from 1997 to 2003 are re-interpreted and combined with new data collected in 2009 and 2010. The age record is analyzed to explore the potential value of groundwater age monitoring for (1) providing additional constraints on the age distribution in mixed-age samples, and (2) identifying temporal changes in groundwater recharge. Motivation for this study is provided by a lack of knowledge of how groundwater recharge and discharge (stream baseflow) in mountain watersheds might respond to climate change, and a resulting need to better understand mountain aquifer residence times, storage, and recharge. Piston-flow ages for the springs generally range from 10 to 50 yr. The plausibility of different age mixing models is tested by comparing observed temporal variations in age with those simulated using simple numerical models, and by examining plots comparing the concentrations of different age tracers. We find that most spring waters are best characterized by a bimodal mixing model consisting of a new (<1 yr old) fraction and a fraction that is older, but still modern (recharged after 1950). Identification of this mixing model would not have been possible without data from multiple age tracers and data from multiple years. Computed mean ages vary substantially (often by 3-7 yr) between sampling events for most springs, including those with ages of 20-50 yr. Mean age variations are likely controlled by variations in the magnitude of the new fraction, which is positively correlated with annual snowpack water content. Most springs show overall upward trends in mean age for the sampling period, consistent with decreasing recharge rates in response to diminishing snowpack. Groundwater age monitoring appears to be a potentially

    2016-01-01

    OBJECTIVES: Smoking prevalence among Korean men in their thirties is substantially high (approximately 50%). An in-depth analysis of smoking trends among young adults in their twenties is necessary to devise antismoking policies for the next 10 years. This study aimed to identify the contributions of age, period, and birth cohort effects on smoking prevalence in young adults. METHODS: Subjects comprised 181,136 adults (83,947 men: 46.3%; 97,189 women: 53.7%) aged 19 to 30 years from the 2008-2013 Korea Community Health Survey. Smoking prevalence adjusted with reference to the 2008 population was applied to the age-period-cohort (APC) model to identify the independent effects of each factor. RESULTS: For men, smoking prevalence rapidly escalated among subjects aged 19 to 22 years and slowed down among those aged 23 to 30 years, declined during 2008 to 2010 but stabilized during 2011 to 2013, and declined in birth cohorts prior to 1988 but stabilized in subjects born after 1988. However, in APC models, smoking prevalence increased with age in the 1988 to 1991 birth cohort. In this birth cohort, smoking prevalence at age 19 to 20 years was approximately 24% but increased to 40% when the subjects turned 23 to 24 years. For women, smoking prevalence was too low to generate consistent results. CONCLUSIONS: Over the past six years and in recent birth cohorts, smoking prevalence in adults aged 19 to 30 years has declined and is stable. Smoking prevalence should be more closely followed as it remains susceptible to an increase depending on antismoking policies or social conditions. PMID:27197740

    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.

    2014-01-01

    Background Cancer has become a global health problem. China still suffers continuous increasing cancer mortality. To study the trend of cancer mortality in rural China, this paper established an Age-Period-Cohort model to discuss the age effect, period effect and cohort effect on cancer mortality in rural China. Methods The data were collected from the “China Health Statistical Yearbook” from 1990 to 2010. Collected data were analyzed by Age-Period-Cohort model and Intrinsic Estimation method. Results The age effect on the total cancer mortality represented a V trend. Compared with Group 0–4, Group 5–9 showed 71.87% lower cancer mortality risk. Compared with Group 5–9, Group 75–79 showed 38 times higher cancer mortality risk. The period effect on the total cancer mortality risk weakened firstly but then increased. It increased by 35.70% from 1990 to 2010, showing an annual average growth of 1.79%. The cohort effect on the total cancer mortality risk weakened by totally 84.94% from 1906–1910 to 2005–2010. Three “deterioration periods” and three “improvement periods” were witnessed during this period. The malignant cancer mortality varied similarly with the total cancer mortality, while benign cancer mortality and other cancer mortality represented different variation laws. Conclusions Although the total cancer mortality risk is increasing at an accelerated rate, cancer mortality risk in recent born year is decreasing, indicating very important impact of social change on the cancer mortality in rural China.

    The calendar represents a few hundreds of biographies of scientists, artists and writers from everywhere, printed in chronological order and adjusted to their birthdays. A number of international and national holydays, including some refering to science are included in the Calendar. A great defect of the calendar is the introduction of the "International day of astrology" in the list of holydays. Another defect is the absence of the indication on the membership to the Communist Party for persons cited from the former Soviet Union.

    The mountain sanctuary Kokino is located in the northeast part of Macedonia, on the summit of a hill of volcanic origin. The archeological research that has been performed for more than a decade confirmed its use as a large extra-urban religious site during the whole period of the Bronze Age. Additional astronomical analyses showed that it has the characteristics of a megalithic observatory, with some of its religious cults related with the motion of the sun, moon and some of the brightest stars. For that purpose the periodic motion of these celestial objects was observed and their position on specific calendar dates marked by stone notches cut in the surrounding rocks. In this paper, we present the results of the astronomical investigation of a group of stone markers aligned toward the specific positions of the full moon and analyze their purpose in creating a simple solar and lunar calendar which was used in planning the everyday life of the Bronze Age people in the region.

  19. Understanding the effects of age, period, and cohort on incidence and mortality rates.

    Time trends for population-based disease rates often are summarized by using direct adjustment by period of diagnosis or death. Similarly, the effect of age often is presented graphically as age-specific rates for a given period of diagnosis. These approaches may be necessary if there is an absence of long-term data, as they provide a natural way for annually updating information when monitoring trends, or they may be a convenient way of summarizing a large amount of data (7, 10, 11, 39, 45). However, these summaries only can adjust for the effect of age in a given period; they implicitly ignore the cohort effect. The effect of cohort is an important factor in understanding time trends for many diseases. Thus, it is not advisable to use data analytic strategies that routinely ignore it. Another alternative to modeling is to give a graphical presentation of the age-specific rates themselves. As I noted in the introduction, some of the first analyses to identify the effect of cohort on diseases, such as tuberculosis and lung cancer, relied entirely on a graphical analysis. Although graphs certainly are an important part of the interpretation of time trends, it would be a mistake to limit your analysis to impressions of points on a graph. For example, such a perusal would not give an objective indication of the statistical significance of a particular pattern. Regression analysis forces us to recognize a fundamental problem with interpreting time trends in disease rates--a problem that you should remember, even when trying to understand a graphical display of time trends in age-specific rates.

  20. Calendars in the Gregorian Spirit

    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].

    A new sample of solar analogs and twin candidates has been constructed and studied, paying particular attention to their light curves from NASA's Kepler mission. This Letter aims to assess their evolutionary status, derive their rotation and ages, and identify those which are solar analogs or solar twin candidates. We separate out the subgiants that compose a large fraction of the asteroseismic sample, and which show an increase in the average rotation period as the stars ascend the subgiant branch. The rotation periods of the dwarfs, ranging from 6 to 30 days and averaging 19 days, allow us to assess their individual evolutionary states on the main sequence and to derive their ages using gyrochronology. These ages are found to be in agreement with a correlation coefficient of r = 0.79 with independent asteroseismic ages, where available. As a result of this investigation, we are able to identify 34 stars as solar analogs and 22 of them as solar twin candidates.

    The aim of this study is to explore the long-term trends of suicide mortality in China. We implemented the age-period-cohort (APC) framework, using data from the Global Burden of Disease Study 2013. Our results showed that the net drift of suicide mortality was −4.727% (95% CI: −4.821% to −4.634%) per year for men and −6.633% (95% CI: −6.751% to −6.515%) per year for women, and the local drift values were below 0 in all age groups (p < 0.01 for all) for both sexes during the period of 1994–2013. Longitudinal age curves indicated that, in the same birth cohort, suicide death risk increased rapidly to peak at the life stage of 20–24 years old and 15–24 years old for men and women, respectively, and then showed a decelerated decline, followed by a rise thereafter after 54 years old for men and a slight one after 69 years old for women. The estimated period and cohort RRs were found to show similar monotonic downward patterns (significantly with p < 0.01 for all) for both sexes, with more quickly decreasing for women than for men during the whole period. The decreasing trend of suicide was likely to be related to the economic rapid growth, improvements in health care, enhancement on the level of education, and increasing awareness of suicide among the public in China. In addition, fast urbanization and the effective control of pesticides and rodenticides might be the special reasons behind these trends we observed in this study. PMID:27527195

    The effects of abattoir, carcase weight (60 or 80 kg HCW), hanging method (Achilles or aitchbone) and ageing period (2 or 7 day post-slaughter) on eating quality attributes of pork were investigated in this 3×2×2×2 factorial study. A total of 144 Large White×Landrace female pigs were slaughtered at one of three abattoirs and sides hung from either the Achilles tendon or the aitchbone. After 24 h chilling, loin (M. longissimus thoracis et lumborum) and topside (M. semimembranosus) muscles were individually vacuum packaged and aged for 2 or 7 days post-slaughter. Consumers (n=852) evaluated eating quality. Neither abattoir nor carcase weight influenced tenderness, flavour or overall liking of pork. Improvements in tenderness, flavour and overall liking were found due to aitchbone hanging (P<0.001) and ageing (P<0.001) for 7 days compared with Achilles-hung carcases and pork aged for 2 days, respectively. This study demonstrated that aitchbone hanging and 7 day ageing can improve eating quality, but these effects were additive as the interaction term was not significant. PMID:24013699

    Background A rapid increase in the prevalence of obesity has been reported in France since 1990. We investigated the impact of birth cohort on the changes in obesity prevalence after taking into account age and survey period. Methods We analyzed data from four national surveys in 1997, 2000, 2003 and 2006. For each survey, self-reported data on weight and height were recorded on mailed questionnaires sent to a sample of 20 000 households, representative of the French population. Obesity was defined according to WHO criteria, BMI ≥ 30 kg/m2. We modeled the prevalence of obesity using logistic regression with age, cohort and period as explanatory variables. As these variables are linearly dependent, only nonlinear effects can be estimated uniquely and interpreted, after including specific chosen constraints in the models. Results There was a progressive increase in the prevalence of obesity between 1997 and 2006, attributable either to a period or to a cohort effect. There was a substantial departure from a linear trend for the cohort effect only, which appeared to be stronger in women: there was an acceleration in the prevalence of obesity with birth cohort for individuals born after the mid-1960s, in both sexes. Conclusions Our results are consistent with previous studies in other countries. Compared with older generations, men and women born in the late 1960s may have been subject to early exposures that increased their lifelong susceptibility to obesity. PMID:20375843

    Previously, Reither et al. (2015) demonstrated that hierarchical age-period-cohort (HAPC) models perform well when basic assumptions are satisfied. To contest this finding, Bell and Jones (2015) invent a data generating process (DGP) that borrows age, period and cohort effects from different equations in Reither et al. (2015). When HAPC models applied to data simulated from this DGP fail to recover the patterning of APC effects, B&J reiterate their view that these models provide "misleading evidence dressed up as science." Despite such strong words, B&J show no curiosity about their own simulated data--and therefore once again misapply HAPC models to data that violate important assumptions. In this response, we illustrate how a careful analyst could have used simple descriptive plots and model selection statistics to verify that (a) period effects are not present in these data, and (b) age and cohort effects are conflated. By accounting for the characteristics of B&J's artificial data structure, we successfully recover the "true" DGP through an appropriately specified model. We conclude that B&Js main contribution to science is to remind analysts that APC models will fail in the presence of exact algebraic effects (i.e., effects with no random/stochastic components), and when collinear temporal dimensions are included without taking special care in the modeling process. The expanded list of coauthors on this commentary represents an emerging consensus among APC scholars that B&J's essential strategy--testing HAPC models with data simulated from contrived DGPs that violate important assumptions--is not a productive way to advance the discussion about innovative APC methods in epidemiology and the social sciences.

    Sea surface temperature (SST), salinity, and flux of terrigenous material oscillated on millennial time scales in the Pleistocene North Atlantic, but there are few records of Holocene variability. Because of high rates of sediment accumulation, Holocene oscillations are well documented in the northern Sargasso Sea. Results from a radiocarbondated box core show that SST was {approximately} 1{degree}C cooler than today {approximately} 400 years ago (the Little Ice Age) and 1700 years ago, and {approximately} 1{degree}C warmer than today 1000 years ago (the Medieval Warm Period). Thus, at least some of the warming since the Little Ice Age appears to be part of a natural oscillation. 39 refs., 4 figs., 1 tab.

    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.

    Ruggles, Clive L. N.

    Over the widest possible range of human cultures, calendars serve to synchronize events, to arrange events chronologically, to provide a temporal framework for referencing and enacting events, and to determine durations (time intervals) between events. They are typically, although not exclusively, linked to one or more astronomical cycles such as the phase cycle of the moon, the seasonal cycle of appearances and disappearances of stars and asterisms, and the seasonal movement of the position of sunrise or sunset to and fro along the horizon. Cultural diversity, together with the fact that the principal astronomical cycles do not fit neatly together, has led different communities to create an extraordinary range of calendars fitted to particular situations and social needs, often showing remarkable ingenuity. This brief survey, which cross-references many other articles in the Handbook, begins by exploring the nature and purpose of calendars in broad terms before proceeding to examine some of the general characteristics of different types of calendar. The next section identifies some of the theoretical and methodological issues facing those who attempt to reconstruct elements of prehistoric calendars from material evidence alone. The article finishes with some remarks concerning calendrical evolution and development.

    The incidence of multiple sclerosis (MS) has doubled in over the last decades in women, whereas it has been almost unchanged in men. The purpose of this study was to investigate the risk factors of early onset multiple sclerosis in women during reproductive years. A retrospective longitudinal study conducted on 200 women aged 15 to 50 years with MS, registered by the MS Society in Isfahan. Data gathering was fulfilled by standard questionnaire including variables about reproductive period, demographic characteristics, and history of diseases. Kaplan-Mayer with log-rank test and Cox regression models were used in predicting of the age of effective factors in onset of MS. P values less than 0.05 were considered statistically significant. The mean age of studied women was 31.77 ± 8.13 years and the mean and median age of onset the symptoms of MS was 26.79 ± 7.77 and 26 years, respectively. Based on the cox results occurring menarche at 15 years and higher increase the risk of MS 2.8-fold than those their menarche occurred at 12 years and lower (HR: 2.81, 95 % CI; 1.58-4.98).In addition, having only one pregnancy is related to higher risk of MS than other parities and increase the risk of MS 4.5-fold comparing to without parities. Age of menarche and parity numbers was the most important reproductive factors of MS in women. Nevertheless, history of autoimmune diseases, animal bite, childhood disease, family history of MS, regional area (tropical), and living in rural area were not related to early onset of MS.

    Oxidative stress is worldwide recognized as a fundamental component of the aging, a process that begins before birth. There is a critical balance between free radical generation and antioxidant defenses. Oxidative stress is caused by an imbalance between the production of free radicals and the ability of antioxidant system to detoxify them. Oxidative stress can occur early in pregnancy and continue in the postnatal period; this damage is implicated in the pathophysiology of pregnancy-related disorders, including recurrent pregnancy loss, preeclampsia and preterm premature rupture of membranes. Moreover, diseases of the neonatal period such as bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, and periventricular leukomalacia are related to free radical damage. The specific contribution of oxidative stress to the pathogenesis and progression of these neonatal diseases is only partially understood. This review summarizes what is known about the role of oxidative stress in pregnancy and in the pathogenesis of common disorders of the newborn, as a component of the early aging process.

    Neonatal foals have unique pharmacokinetics, which may lead to accumulation of certain drugs when adult horse dosage regimens are used. Given its lipophilic nature and requirement for hepatic metabolism, metronidazole may be one of these drugs. The purpose of this study was to determine the pharmacokinetic profiles of metronidazole in twelve healthy foals at 1-2.5 days of age when administered as a single intravenous (IV) and intragastric (IG) dose of 15 mg/kg. Foals in the intravenous group were studied a second time at 10-12 days of age to evaluate the influence of age on pharmacokinetics within the neonatal period. Blood samples were collected at serial time points after metronidazole administration. Metronidazole concentration in plasma was measured using LC-MS. Pharmacokinetic parameters were determined using noncompartmental analysis and compared between age groups. At 1-2.5 days of age, the mean peak plasma concentration after IV infusion was 18.79 ± 1.46 μg/mL, elimination half-life was 11.8 ± 1.77 h, clearance was 0.84 ± 0.13 mL/min/kg and the volume of distribution (steady-state) was 0.87 ± 0.07 L/kg. At 10-12 days of age, the mean peak plasma concentration after IV infusion was 18.17 ± 1.42 μg/mL, elimination half-life was 9.07 ± 2.84 h, clearance was 1.14 ± 0.21 mL/min/kg and the volume of distribution (steady-state) was 0.88 ± 0.06 L/kg. Oral approximated bioavailability was 100%. Cmax and Tmax after oral dosing were 14.85 ± 0.54 μg/mL and 1.75 (1-4) h, respectively. The elimination half-life was longer and clearance was reduced in neonatal foals at 1-2.5 days as compared to 10-12 days of age (P = 0.006, P = 0.001, respectively). This study warrants consideration for altered dosing recommendations in foals, especially a longer interval (12 h). PMID:25271172

    According to model calculations, the meridional circulation is expected to intensify as a result of climate change, and mean age of stratospheric air is expected to decrease. However, an observational data set presented recently (Engel et al., 2009) and consisting of 27 balloon samples of the age of air tracers carbon dioxide and sulfur hexafluoride covering the years 1975 to 2005 did not confirm the model predictions. As a contribution to the ongoing discussion, an extensive observational data set, consisting of more than 1 Million SF6 vertical profiles distributed globally is presented here. It has been derived from the MIPAS instrument covering the period 2002 to 2010 and has been converted into mean age of stratospheric air by referring to a combined data set of in-situ and flask global mean tropospheric SF6 measurements provided by NOAA/ESRL. During conversion into age of air, the non-linearity of tropospheric SF6 increase has been corrected for by convolution with the age spectrum within an iterative approach. Monthly zonal means of mean age of air, binned at 10 deg latitude and 1-2 km altitude, were analyzed with respect to their temporal variation by fitting a regression model consisting of a constant and a linear increase term, 2 proxies for the QBO variation, sinusoidal terms for the seasonal and semi-annual variation and overtones for the correction of the shapes to the observed data set. The impact of subsidence of mesospheric SF6-depleted air and in-mixing into non-polar latitudes on mid-latitudinal absolute age of air and the age-of-air linear increase was assessed and found to be small. The linear increase of mean age of stratospheric air was found to be positive and partly larger than the trend derived by Engel et al. (2009) for most of the Northern mid-latitudes, the middle stratosphere in the tropics, and parts of the Southern mid-latitudes, as well as for the Southern polar upper stratosphere. Multi-year decrease of age of air was found for the

    We acquired large data sets of calendar performance from two autistic calendar savants, DG and RN. An analysis of their errors and reaction times revealed that (1) both individuals had knowledge of calendar information from a limited range of years; (2) there was no evidence for the use of memorized anchor dates that could, by virtue of counting away from the anchors, allow correct responses to questions about other dates; and (3) the two individuals differed in their calendar knowledge, as well as in their ability to perform secondary tasks in which calendar knowledge was assessed indirectly. In view of the fact that there are only 14 possible annual calendars, we suggest that both savants worked by memorizing these 14 possible calendar arrangements. PMID:17686947

  17. Should Age-Period-Cohort Studies Return to the Methodologies of the 1970s?

    Social scientists have recognized the importance of age-period-cohort (APC) models for half a century, but have spent much of this time mired in debates about the feasibility of APC methods. Recently, a new class of APC methods based on modern statistical knowledge has emerged, offering potential solutions. In 2009, Reither, Hauser and Yang used one of these new methods – hierarchical APC (HAPC) modeling – to study how birth cohorts may have contributed to the U.S. obesity epidemic. They found that recent birth cohorts experience higher odds of obesity than their predecessors, but that ubiquitous period-based changes are primarily responsible for the rising prevalence of obesity. Although these findings have been replicated elsewhere, recent commentaries by Bell and Jones call them into question – along with the new class of APC methods. Specifically, Bell and Jones claim that new APC methods do not adequately address model identification and suggest that “solid theory” is often sufficient to remove one of the three temporal dimensions from empirical consideration. They also present a series of simulation models that purportedly show how the HAPC models estimated by Reither et al. (2009) could have produced misleading results. However, these simulation models rest on assumptions that there were no period effects, and associations between period and cohort variables and the outcome were perfectly linear. Those are conditions under which APC models should never be used. Under more tenable assumptions, our own simulations show that HAPC methods perform well, both in recovering the main findings presented by Reither et al. (2009) and the results reported by Bell and Jones. We also respond to critiques about model identification and theoretically-imposed constraints, finding little pragmatic support for such arguments.

    Although treatment utilization for depression and anxiety symptoms has increased substantially in the United States and elsewhere, it remains unclear whether the underlying population distribution of psychological distress is changing over time. We estimated age, period, and cohort effects using data from 2 countries over more than 20 years, including National Health Interview Surveys from 1997 to 2010 (n = 447,058) and Canadian Community Health Surveys from 2000 to 2007 (n = 125,306). Psychological distress was measured with the Kessler Psychological Distress Scale. By period, both countries showed the highest levels of psychological distress in 2001 and the lowest levels in 2007. By age, psychological distress was highest in adolescence and during the late 40s and early 50s. By cohort, Canadian Community Health Survey results indicated a decreasing cohort effect among those born in 1922–1925 through 1935–1939 (β = −0.36, 95% confidence interval: −0.45, −0.27) and then a continuously increasing cohort effect during the remainder of the 20th century through 1989–1992 (β = 0.49, 95% confidence interval: 0.38, 0.61). The National Health Interview Survey data captured earlier-born cohorts and indicated an increased cohort effect for the earliest born (for 1912–1914, β = 0.44, 95% confidence interval: 0.26, 0.61). In sum, individuals in the oldest and more recently born birth cohorts have higher mean psychological distress symptoms compared with those born in midcentury, underscoring the importance of a broad, population-level lens for conceptualizing mental health.

    One of the core primary care reform initiatives seen across provinces in Canada is the introduction of inter-professional primary healthcare teams in which family physicians are encouraged to collaborate with other health professionals. Although a higher proportion of physicians are collaborating with various health professionals now compared to the previous decade, a substantial number of physicians still do not work in a collaborative setting. The objective of this paper is to examine the age, period and cohort effects of Canadian family physicians' decisions to collaborate with seven types of health professionals: specialists, nurse practitioners, nurses, dieticians, physiotherapists, psychologists and occupational therapists. To this end, this paper employs a multivariate probit model consisting of seven equations and a cross-classified fixed-effects strategy to explain the collaborative decisions of family physicians. Utilizing three cross-sectional physician surveys from Canada over the 2001-2007 period, cohorts are defined over five-year intervals according to their year of graduation from medical school. We find that newer cohorts of physicians are more likely to collaborate with dieticians, physiotherapists, psychologists and occupational therapists; newer female cohorts are more likely to collaborate with nurses while newer male cohorts are less likely to collaborate with nurses but more likely to collaborate with specialists. Older physicians are more likely to collaborate with specialists, physiotherapists, psychologists, and occupational therapists; the age effect for nurses is U-shaped for male physicians while it is inverse U-shaped for females. Family physicians are collaborating more with all seven health professionals in 2004 and 2007 compared to 2001. Belonging to a group practice has a largely positive influence on collaborations; and being paid by a fee-for-service remuneration scheme exerts a negative influence on collaboration, ceteris

    An extensive observational data set from MIPAS measurements, consisting of more than one million SF6 vertical profiles distributed globally has been condensed into monthly zonal means of mean age of air for the period September 2002 to January 2010, binned at 10° latitude and 1-2 km altitude. The data were analysed with respect to their temporal variation by fitting a regression model consisting of: a constant and a linear increase term, 2 proxies for the QBO variation, sinusoidal terms for the seasonal and semi-annual variation and overtones for the correction of the shapes to the observed data set. The impact of subsidence of mesospheric SF6-depleted air and in-mixing into non-polar latitudes on mid-latitudinal age of air and its linear increase was assessed and found to be small. The linear increase of mean age of stratospheric air was found to be positive and partly larger than the trend derived by Engel et al. (2009) for most of the Northern mid-latitudes, the middle stratosphere in the tropics, and parts of the Southern mid-latitudes, as well as for the Southern polar upper stratosphere. Multi-year decrease of age of air was found for the lowermost and the upper stratospheric tropics, for parts of Southern mid-latitudes, and for the Northern polar regions. Analyses of the amplitudes and phases of the seasonal variation shed light on the coupling between different stratospheric regions. In particular, the Northern mid-latitude stratosphere is well coupled to the tropics, while the Northern lowermost mid-latitudinal stratosphere is decoupled, confirming the separation of the shallow branch of the Brewer-Dobson circulation from the deep branch. We suggest an overall increased tropical upwelling, together with a weakening of mixing barriers, especially in the Northern hemisphere, as possible explanations for the observed patterns.

    We present paleoclimate evidence for rapid (< 100 years) shifts of ??? 2-4??C in Chesapeake Bay (CB) temperature ???2100, 1600, 950, 650, 400 and 150 years before present (years BP) reconstructed from magnesium/calcium (Mg/Ca) paleothermometry. These include large temperature excursions during the Little Ice Age (???1400-1900 AD) and the Medieval Warm Period (???800-1300 AD) possibly related to changes in the strength of North Atlantic thermohaline circulation (THC). Evidence is presented for a long period of sustained regional and North Atlantic-wide warmth with low-amplitude temperature variability between ???450 and 1000 AD. In addition to centennial-scale temperature shifts, the existence of numerous temperature maxima between 2200 and 250 years BP (average ???70 years) suggests that multi-decadal processes typical of the North Atlantic Oscillation (NAO) are an inherent feature of late Holocene climate. However, late 19th and 20th century temperature extremes in Chesapeake Bay associated with NAO climate variability exceeded those of the prior 2000 years, including the interval 450-1000 AD, by 2-3??C, suggesting anomalous recent behavior of the climate system. ?? 2002 Elsevier Science B.V.

    We present high precision photoelectric photometry of a sample of bright, single F, G, and K- type main-sequence and subgiant stars. Several of the stars are members of clusters or moving groups and thus have well determined ages. The majority of the stars are main-sequence to subgiant G-types stars that range in age from 70 Myr to 10 Gyr with directly measured rotation periods from 2.7 days up to 40-50 days. The observations have been carried out with Automatic Photometric Telescopes (APTs) located on Mt Hopkins, Arizona beginning in 1988; standard UBVRI \\ or uvby \\ filters were used. As expected, the youngest, fastest rotating stars in the sample typically have the largest, rotationally modulated starspot light variations. Some of the stars show relatively rapid changes in their light curves that are explained by differential rotation of the starspot groups. In addition, some of the stars that have been observed over several years show long-term, seasonal trends in their mean brightness levels that most likely arise from starspot cycles. The starspot properties (areal coverage, distribution, and temperature) are determined from the modelling of the multiwavelength light curves. For certain stars, comparisons of these photospheric starspots properties to their corresponding chromospheric, transition region, and coronal activity indicators obtained in the UV, EUV \\ and X-ray are presented and discussed. Analogies are also made to the magnetic properties of the Sun. This research is supported by NSF AST 86-16362, NASA NAG5-2160, and NAG5-2494.

  10. Historical and cultural background of the calendar of Yunnan minorities

    NASA Astrophysics Data System (ADS)

    Li, Wei-Bao

    Among the rich and varied culture of Yunnan minorities, the so-called Phenology Calendar, the solar calendar, and the lunar calendar had simultaneously existed for a long time, and suited the development of society and economics of various minorities in Yunnan. This phenomenon is closely associated with the migration of nationality. The YUE nation and the QIANG nation of early antiquity migrated to Yunnan as early as the ZHAN-GUO dynasty, possibly even in the New Stone Age. Large-scale migration of nation means migration of their culture, and the migration of nation may either promote the development of their culture or make their culture go backwards, depending on whether the nation draw advanced culture of other nation to develop themselves or not. Regional common cultural phenomena may be formed with the acception of some traditional culture of other nations, and the drum culture is a typical examples beside calendar.

  11. The Egyptian Civil Calendar: a Masterpiece to Organize the Cosmos

    2009-08-01

    The ancient Egyptians had just one calendar in operation, the civil one, during most of their history and before the overwhelming influence of Hellenic culture. This calendar may have been invented for a specific purpose in the first half of the third millennium B.C., when the previous local Nile-based lunar calendars were rendered useless, as the result of the unification of the country and new social, economic and administrative requirements. The civil calendar always started at the feast of Wepet Renpet in the first day of the first month of the Inundation season (I Akhet 1). Its peculiar length of only 365 days (without leap years) might have been established from simple astronomical (presumably solar) observations. Consequently, Wepet Renpet wandered throughout the seasons in a period close to 15 centuries. Our research has shown that this phenomenology was reflected in the Egyptian worldview by the orientation of most important sacred structures accordingly.

    The current paper describes the age, period and cohort effects on breast cancer mortality in Taiwan. Female breast cancer mortality data were collected from the Taiwan death registries for 1971-2010. The annual percentage changes, age- standardised mortality rates (ASMR) and age-period-cohort model were calculated. The mortality rates increased with advancing age groups when fixing the period. The percentage change in the breast cancer mortality rate increased from 54.79% at aged 20-44 years, to 149.78% in those aged 45-64 years (between 1971-75 and 2006-10). The mortality rates in the 45-64 age group increased steadily from 1971 to 1975 and 2006-10. The 1951 birth cohorts (actual birth cohort; 1947-55) showed peak mortalities in both the 50-54 and 45-49 age groups. We found that the 1951 birth cohorts had the greatest mortality risk from breast cancer. This might be attributed to the DDT that was used in large amounts to prevent deaths from malaria in Taiwan. However, future researches require DDT data to evaluate the association between breast cancer and DDT use. PMID:25020211

  13. Ancient Persian Skywatching and Calendars

    NASA Astrophysics Data System (ADS)

    Sołtysiak, Arkadiusz

    The peoples of Iran used lunisolar calendars until the early fifth century BCE when the 365-day calendar with 30 months and 5 epagomenal days was introduced. This calendar was not corrected to the actual length of the tropical year, and therefore, seasonal festivals gradually moved away from their seasons. Finally, around the turn of the fifth century CE, a partially successful calendar reform was undertaken, and the feasts were restored to their original seasons. In that time, Sasanian kings were interested in astrology, and some Greek and Hindu astrological texts were translated into Persian, but there is no evidence of indigenous contributions to skywatching.

    Background The objective of this study was to examine long-term trends in rates of ischaemic heart disease (IHD) mortality, a leading cause of mortality in Hungary. The study examined the effects of age, period, and cohort on IHD mortality rates and compared mortality rates between the capital (Budapest) and non-capital counties. Methods Data on IHD deaths and population censuses were obtained from the Hungarian Central Statistical Office. Age-period-cohort analysis utilized nine age-group classes for ages 40 to 84 years, eight time periods from 1970 to 2009, and 16 birth cohorts from 1886 to 1969. Results Age-adjusted IHD mortality rates for men and for women generally increased from 1970 to 1993 and from 1980 to 1999, respectively, decreasing thereafter for both sexes. IHD mortality rates for men and for women from Budapest were lower from 1991 and from 1970, respectively, than corresponding rates in non-capital counties, with the difference increasing after 1999. Age had a more significant influence on mortality rates for women than for men. The period effect increased from 1972 to 1982 and decreased thereafter for men, while the period effect decreased consistently for women from 1972 to 2007. The decline in period effect for both sexes was larger for individuals from the capital than for those from non-capital counties. The cohort effect for both sexes declined from birth years 1890 to 1965, with a steeper decline for individuals from the capital than for those from non-capital counties. Conclusions The findings indicate a need for programs in Hungary for IHD prevention, especially for non-capital counties. PMID:25986153

    Study purpose Whether or not socioeconomic status (SES)-related differences in the health of hemodialysis patients differ by age, period, and birth cohort remains unclear. We examined whether SES-related gaps in physical and mental health change with age, period, and birth cohort for hemodialysis patients. Methods Data were obtained from repeated cross-sectional surveys conducted in 1996, 2001, 2006, and 2011, with members of a national patients’ association as participants. We used raking adjustment to create a database which had similar characteristics to the total sample of dialysis patients in Japan. SES was assessed using family size-adjusted income levels. We divided patients into three groups based on their income levels: below the first quartile, over the second quartile and under the third quartile, and over the fourth quartile. We used the number of dialysis complications as a physical health indicator and depressive symptoms as a mental health indicator. We used a cross-classified random-effects model that estimated fixed effects of age categories and period as level-1 factors, and random effects of birth cohort as level-2 factors. Results Relative risk of dialysis complications in respondents below the first quartile compared with ones over the fourth quartile was reduced in age categories >60 years. Mean differences in depressive symptoms between respondents below the first quartile and ones over the fourth quartile peaked in the 50- to 59-year-old age group, and were reduced in age groups >60 years. In addition, mean differences varied across periods, widening from 1996 to 2006. There were no significant birth cohort effects on income differences for dialysis complications or depressive symptoms. Conclusion The number of dialysis complications and depressive symptoms in dialysis patients were affected by income differences, and the degree of these differences changed with age category and period.

  16. Growth of river delta networks: Thresholds, periodicity, aging and self similarity (Invited)

    2010-12-01

    The surfaces of river deltas and alluvial fans (collectively fans) are often dissected by a small number of channels radiating from the fan apex. These dispersive, depositional systems do not exhibit the fractal scaling typical of erosional drainage networks. On long timescales, fan channels migrate via avulsion - the process of channel bed deposition and abandonment. What governs the selection of new flow paths, or the ultimate number of active channels, is poorly understood. Here we present results of an experimental fan that allow us to examine the growth of a depositional channel network. Flow over the fan collapses into a single channel whose dimensions adjust to threshold transport conditions for the imposed sediment load. This channelization causes localized shoreline growth, which diminishes transport capacity of the channel until the slope drops below the threshold value. This leads to deposition within the channel and widespread flooding; avulsion is completed when a new channel path is selected. This cycle is remarkably periodic, and dynamics suggest that fan slope oscillates between two thresholds - entrainment and distrainment - analogous to static and dynamic angles of repose in grain flows. Selection of a new flow path is inherently stochastic, but previously abandoned channels act as significant attractors for the flow. In the early stages of fan growth, new channels are likely to be created. Once a critical density of flow paths has been established, however, the flow oscillates among the same 3-5 channels indefinitely. These dynamics are similar to the aging phenomenon observed in the growth of fractures in brittle materials under stress. We demonstrate that a directed random walk model with memory quantitatively reproduces these dynamics and limiting behavior, and is consistent with natural fans. Because our experimental fan is built by the recurring avulsion sequence, its shoreline shape is a series of lobes that indicate persistent upstream

    This study aimed to analyze temporal trends by gender and age in Clostridium difficile infection (CDI)-related hospitalization rates in the Autonomous Community of Madrid (Spain) over a 12-year period. A population-based cross-sectional study of all hospital admissions with a CDI diagnosis from 2003 to 2014 was carried out. Annual age-specific hospitalization rates were calculated by gender. All the analyses were performed separately for total hospitalizations and hospitalizations with CDI as the primary diagnosis. Joinpoint regression models were used to analyze time trends. A total of 13,526 hospital discharges were identified (26.8 % with CDI as the primary diagnosis). In both sexes, a gradient in age-specific rates was observed, ranging in 2014 from 5.92 hospitalizations per 100,000 person-years in patients <15 years of age to 378.96 in patients ≥85 years of age. Since 2009, in the age group of 15-44 years, both men and women presented an increasing trend of around 18 %. A significantly increasing trend was detected in women of age 45-84 years, with an estimated annual percentage of change of 7.6 % in the age group of 45-64 years, and rounding with 4.5 % in the age group of 65-84 years. In men of age 45-64 years, the average annual percentage of increase was 4.7 %, and it was 21.1 % between 2010 and 2014 in the age group of 65-74 years. No trends were identified in the 85 years and over age group. Surveillance methods to assess trends by age group should be implemented. Preventive and therapeutic initiatives should remain a priority. PMID:27056555

  1. Black bear femoral geometry and cortical porosity are not adversely affected by ageing despite annual periods of disuse (hibernation)

    Disuse (i.e. inactivity) causes bone loss, and a recovery period that is 2–3 times longer than the inactive period is usually required to recover lost bone. However, black bears experience annual disuse (hibernation) and remobilization periods that are approximately equal in length, yet bears maintain or increase cortical bone material properties and whole bone mechanical properties with age. In this study, we investigated the architectural properties of bear femurs to determine whether cortical structure is preserved with age in bears. We showed that cross-sectional geometric properties increase with age, but porosity and resorption cavity density do not change with age in skeletally immature male and female bears. These findings suggest that structural properties substantially contribute to increasing whole bone strength with age in bears, particularly during skeletal maturation. Porosity was not different between skeletally immature and mature bears, and showed minimal regional variations between anatomical quadrants and radial positions that were similar in pattern and magnitude between skeletally immature and mature bears. We also found gender dimorphisms in bear cortical bone properties: females have smaller, less porous bones than males. Our results provide further support for the idea that black bears possess a biological mechanism to prevent disuse osteoporosis. PMID:17261138

  2. Sex and age differences in hibernation patterns of common hamsters: adult females hibernate for shorter periods than males.

    In this study, we investigated the timing and duration of hibernation as well as body temperature patterns in free-ranging common hamsters (Cricetus cricetus) with regard to sex and age differences. Body temperature was recorded using subcutaneously implanted data loggers. The results demonstrate that although immergence and vernal emergence sequences of sex and age groups resembled those of most hibernators, particularly adult females delayed hibernation onset until up to early January. Thus, in contrast to other hibernators, female common hamsters hibernated for shorter periods than males and correspondingly spent less time in torpor. These sex differences were absent in juvenile hamsters. The period between the termination of hibernation and vernal emergence varied among individuals but did not differ between the sex and age groups. This period of preemergence euthermy was related to emergence body mass: individuals that terminated hibernation earlier in spring and had longer euthermic phases prior to emergence started the active season in a better condition. In addition, males with longer periods of preemergence euthermy had larger testes at emergence. In conclusion, females have to rely on sufficient food stores but may adjust the use of torpor in relation to the available external energy reserves, whereas males show a more pronounced energy-saving strategy by hibernating for longer periods. Nonetheless, food caches seem to be important for both males and females as indicated by the euthermic preemergence phase and the fact that some individuals, mainly yearlings, emerged with a higher body mass than shortly before immergence in autumn.

    This study investigated the effects of using medium voltage (~300 V) electrical stimulation (ES) and ageing on alpaca meat. A total of 50 huacaya alpacas were distributed across three age groups (18, 24 and 36 months) and two genders (females and castrated males). At 24h post mortem the m. longissimus thoracis et lumborum (LL) and m. semimembranosus (SM) muscles were removed and aged for either 5 or 10 days. In comparison to non-ES samples, ES significantly reduced: LL purge values by 3.0% and LL shear force (SF) at 5 and 10 days (by 21.6N and ageing further reduced tenderness by 6.6N), and SM SF by 5.8 N with significant age effects observed in both ES and non-ES SM samples, such that SF increased by 0.53 N with each month increase in animal age. Consumers rated ES samples higher on tenderness, juiciness, flavour and overall rating. ES and ageing of alpaca carcasses are recommended. PMID:26331964

  4. The relationship between the age of onset of musical training and rhythm synchronization performance: validation of sensitive period effects.

    A sensitive period associated with musical training has been proposed, suggesting the influence of musical training on the brain and behavior is strongest during the early years of childhood. Experiments from our laboratory have directly tested the sensitive period hypothesis for musical training by comparing musicians who began their training prior to age seven with those who began their training after age seven, while matching the two groups in terms of musical experience (Watanabe et al., 2007; Bailey and Penhune, 2010, 2012). Using this matching paradigm, the early-trained groups have demonstrated enhanced sensorimotor synchronization skills and associated differences in brain structure (Bailey et al., 2013; Steele et al., 2013). The current study takes a different approach to investigating the sensitive period hypothesis for musical training by examining a single large group of unmatched musicians (N = 77) and exploring the relationship between age of onset of musical training as a continuous variable and performance on the Rhythm Synchronization Task (RST), a previously used auditory-motor RST. Interestingly, age of onset was correlated with task performance for those who began training earlier, however, no such relationship was observed among those who began training in their later childhood years. In addition, years of formal training showed a similar pattern. However, individual working memory scores were predictive of task performance, regardless of age of onset of musical training. Overall, these results support the sensitive period hypothesis for musical training and suggest a non-linear relationship between age of onset of musical training and auditory-motor rhythm synchronization abilities, such that a relationship exists early in childhood but then plateaus later on in development, similar to maturational growth trajectories of brain regions implicated in playing music.

    Rotation periods are increasingly being used to derive ages for cool single field stars. Such ages are based on an empirical understanding of how cool stars spin down, acquired by constructing color-period diagrams (CPDs) for a series of open clusters. Our main aims here are to construct a CPD for M 48, to compare this with other clusters of similar age to check for consistency, and to derive a rotational age for M 48 using gyrochronology. We monitored M 48 photometrically for over 2 months with AIP's STELLA I 1.2 m telescope and the WiFSIP 4K imager in Tenerife. Light curves with 3 mmag precision for bright (V ~ 14 mag) stars were produced and then analysed to provide rotation periods. A cluster CPD has then been constructed. We report 62 rotation periods for cool stars in M 48. The CPD displays a clear slow/I-sequence of rotating stars, similar to those seen in the 625 Myr-old Hyades and 590 Myr-old Praesepe clusters, and below both, confirming that M 48 is younger. A similar comparison with the 250 Myr-old M 34 cluster shows that M 48 is older and does not possess any fast/C-sequence G or early K stars like those in M 34, although relatively fast rotators do seem to be present among the late-K and M stars. A more detailed comparison of the CPD with rotational evolution models shows that the cluster stars have a mean age of 450 Myr, and its (rotating) stars can be individually dated to ± 117 Myr (26%). Much of this uncertainty stems from intrinsic astrophysical spread in initial periods, and almost all stars are consistent with a single age of 450 Myr. The gyro-age of M 48 as a whole is 450 ± 50 Myr, in agreement with the previously determined isochrone age of 400 ± 100 Myr.

    Accurate high-precision [sup 14]C dating (i.e., [plus minus] 20 yr precision or less on the [sup 14]C date) provides the narrowest calendrical band width and, hence, the best age range determination possible. However, because of the structure in the [sup 14]C calibration curve, the calendar age range for a given [sup 14]C precision is not constant throughout the calibration range. In this study, they quantify the calendar band widths for a range of [sup 14]C precisions throughout the calibration range. They show that an estimate of the likely calendar band width in years can be obtained from the expression: Band width (yr) = 2.12 x [sup 14]C precision (1 [sigma]) + 54.6. They also show that calendar band widths are widest around 4000 Bp at the start of the Bronze Age, and become narrow through the later Bronze Age and Iron Age and back into the Neolithic.

    The use of astronomy for collective purposes, both religious and political, is apparent in the earliest astronomical records, from the evidence for Palaeolithic lunar calendars to megalithic monuments and Mesopotamian celestial-omen reports. This paper will consider the application of the heavens to the organisation of the ‘Cosmic State’, the human polity modelled on the assumption of a close relationship between society on the one hand and planetary and stellar patterns on the other. I will also examine the foundation of Baghdad within the tradition of celestial town planning and argue that the city may be seen as a ‘talisman’, designed to connect heaven to Earth and ensure peace, stability and political success by harmonising time and space.

    The role and importance of the number of awakenings and their duration in relation to increasing intervening wakefulness were investigated. The data were collected from a group of 38 subjects suffering from chronic primary insomnia, aged 17-70 years, polygraphically recorded; the analysis was made on the second night. With age, the total quantity of intervening wakefulness increases more quickly than the total number of awakenings. The amount of wakefulness due to awakenings lasting greater than or equal to 3 min increases with age. Older insomniacs wake up somewhat more often but, above all, they go back to sleep less quickly. Our hypothesis is that in old patients insomnia is linked to an increase in stability of wakefulness. PMID:7313262

    Objectives. This study delineates activities of daily living (ADL) and instrumental activities of daily living (IADL) black–white disparity trends by age, period, and cohort (APC) and explores sociodemographic contributors of cohort-based disparity trends. Method. We utilized multiple cross-sectional waves of National Health Interview Survey data (1982–2009) to describe APC trends of ADL and IADL disparities using a cross-classified random effect model. Further, we decomposed the cohort-based disparity trends using Fairlie’s decomposition method for nonlinear outcomes. Results. The crossover ADL and IADL disparities (whites > blacks) occurring at age 75 increased with age and reached a plateau at age of 80, whereas period-based ADL and IADL disparities remained constant for the past 3 decades. The cohort disparity trends for both disabilities showed a decline with each successive cohort except for ADL disparity among women. Discussion. We examined the role of aging on racial disparity in disability and found support for the racial crossover effect. Further, the racial disparity in disability will disappear should the observed pattern of declining cohort-based ADL and IADL disparities persist. Although education, income, and marital status are important sociodemographic contributors to cohort disparity trends, future studies should investigate individual behavioral health determinants and cohort-specific characteristics that explain the cohort-based racial difference in ADL and IADL disabilities.

    Rughiniș, Cosima; Humă, Bogdana

    2015-12-01

    In this paper we argue that quantitative survey-based social research essentializes age, through specific rhetorical tools. We outline the device of 'socio-demographic variables' and we discuss its argumentative functions, looking at scientific survey-based analyses of adult scientific literacy, in the Public Understanding of Science research field. 'Socio-demographics' are virtually omnipresent in survey literature: they are, as a rule, used and discussed as bundles of independent variables, requiring little, if any, theoretical and measurement attention. 'Socio-demographics' are rhetorically effective through their common-sense richness of meaning and inferential power. We identify their main argumentation functions as 'structure building', 'pacification', and 'purification'. Socio-demographics are used to uphold causal vocabularies, supporting the transmutation of the descriptive statistical jargon of 'effects' and 'explained variance' into 'explanatory factors'. Age can also be studied statistically as a main variable of interest, through the age-period-cohort (APC) disambiguation technique. While this approach has generated interesting findings, it did not mitigate the reductionism that appears when treating age as a socio-demographic variable. By working with age as a 'socio-demographic variable', quantitative researchers convert it (inadvertently) into a quasi-biological feature, symmetrical, as regards analytical treatment, with pathogens in epidemiological research.

    Adults as well as infants have the capacity to discriminate languages based on visual speech alone. Here, we investigated whether adults' ability to discriminate languages based on visual speech cues is influenced by the age of language acquisition. Adult participants who had all learned English (as a first or second language) but did not speak French were shown faces of bilingual (French/English) speakers silently reciting sentences in either language. Using only visual speech information, adults who had learned English from birth or as a second language before the age of 6 could discriminate between French and English significantly better than chance. However, adults who had learned English as a second language after age 6 failed to discriminate these two languages, suggesting that early childhood exposure is crucial for using relevant visual speech information to separate languages visually. These findings raise the possibility that lowered sensitivity to non-native visual speech cues may contribute to the difficulties encountered when learning a new language in adulthood. PMID:24312020

    The new brighter calibration of absolute luminosities of RR Lyrae stars by about 0.25 mag as a function of metallicity via the Oosterhoff period effect gives a revised age of the Galactic globular cluster system as 14 Gyr when used with the oxygen-enhanced main-sequence termination models of Bergbush and VandenBerg (1992). There is no correlation of cluster age with metallicity. The presence or absence of age differences between any two clusters is neither proof nor disproof of the Eggen-Lynden Bell-Sandage model of the formation of the Galaxy by collapse. If there were different density regimes within the initial density fluctuation that was the protogalaxy, then there has been a hierarchy of collapse times for the various parts of the present Galaxy. The age of the universe is 15 Gyr, based on the age of the Galaxy at 14 Gyr, to which 1 Gyr is added for the gestation time of the galaxies. The ratio of this age to the inverse Hubble constant with H(0) about 45 km/s Mpc, based on a recent concordant determination using supernovae of type Ia, is close to the critical value of 2/3 required if the deceleration is caused by a mean density just equal to that needed for closure. For the first time, these new data give the possibility that Omega = 1 from this timing test.

    The objectives of the IPP Project--Periodic Inspection on Crop Sprayers--are to develop methods for sprayer certification, analyze quality on spray operation, propose an inspection system for crop sprayers in Brazil, improve environmental quality on spray operation, and reduce costs on chemical control for plant protection systems. Periodic inspections on crop sprayers are performed in several countries and are compulsory in most of them, and it is becoming an important tool for improvement and optimization of use of chemicals. The IPP Project in Brazil is funded by FAPESP--Fundação de Amparo à Pesquisa do Estado de São Paulo. The results so far showed that all the sprayers presented failures. However, most of them could be approved with minor services. As an example, 56.6% of the sprayers with more than 2 years of use presented leaks, 47% of them had damaged hoses and 80.5% presented bad tips (nozzles). These results indicate the need for better procedures of use and maintenance of sprayers, justifying the periodic inspection system. PMID:15656181

    Background The incorporation of diagnostic and therapeutic improvements, as well as the different smoking patterns, may have had an influence on the observed variability in renal cancer mortality across Europe. This study examined time trends in kidney cancer mortality in fourteen European countries during the last two decades of the 20th century. Methods Kidney cancer deaths and population estimates for each country during the period 1981–2000 were drawn from the World Health Organization Mortality Database. Age- and period-adjusted mortality rates, as well as annual percentage changes in age-adjusted mortality rates, were calculated for each country and geographical region. Log-linear Poisson models were also fitted to study the effect of age, death period, and birth cohort on kidney cancer mortality rates within each country. Results For men, the overall standardized kidney cancer mortality rates in the eastern, western, and northern European countries were 20, 25, and 53% higher than those for the southern European countries, respectively. However, age-adjusted mortality rates showed a significant annual decrease of -0.7% in the north of Europe, a moderate rise of 0.7% in the west, and substantial increases of 1.4% in the south and 2.0% in the east. This trend was similar among women, but with lower mortality rates. Age-period-cohort models showed three different birth-cohort patterns for both men and women: a decrease in mortality trend for those generations born after 1920 in the Nordic countries, a similar but lagged decline for cohorts born after 1930 in western and southern European countries, and a continuous increase throughout all birth cohorts in eastern Europe. Similar but more heterogeneous regional patterns were observed for period effects. Conclusion Kidney cancer mortality trends in Europe showed a clear north-south pattern, with high rates on a downward trend in the north, intermediate rates on a more marked rising trend in the east than in the

    Continuous spectral EEG activity monitoring has been used in adults as a monitor of brain activity during anesthesia. It has not been used in infants. We studied 22 infants less than 7 months old undergoing minor surgery. Halothane alone or minimal Halothane anesthesia associated with caudal epidural anesthesia were used. Life-Scan analysis, in spite of wide individual variations, allowed us to detect infraclinical hypoxia episodes, it provided informations about operative confort, depth of anesthesia and added in the post-operative period an objective criteria to clinical evaluation of pain. A wide use of such a monitoring is warranted in infants. PMID:2631593

    The experiences we engage in during childhood can stay with us well into our adult years. The idea of a sensitive period--a window during maturation when our brains are most influenced by behavior--has been proposed. Work from our laboratory has shown that early-trained musicians (ET) performed better on visual-motor and auditory-motor synchronization tasks than late-trained musicians (LT), even when matched for total musical experience. Although the groups of musicians showed no cognitive differences, working memory scores correlated with task performance. In this study, we have replicated these findings in a larger sample of musicians and included a group of highly educated nonmusicians (NM). Participants performed six woodblock rhythms of varying levels of metrical complexity and completed cognitive subtests measuring verbal abilities, working memory, and pattern recognition. Working memory scores correlated with task performance across all three groups. Interestingly, verbal abilities were stronger among the NM, while nonverbal abilities were stronger among musicians. These findings are discussed in context of the sensitive period hypothesis as well as the debate surrounding cognitive differences between musicians and NM. PMID:22524355

    Background Studies have shown that hepatitis C virus (HCV) infection increased during the past decades in China. However, little evidence is available on when, where, and who were infected with HCV. There are gaps in knowledge on the epidemiological burden and evolution of the HCV epidemic in China. Methods Data on HCV cases were collected by the disease surveillance system from 2005 to 2012 to explore the epidemic in Henan province. Spatiotemporal scan statistics and age-period-cohort (APC) model were used to examine the effects of age, period, birth cohort, and spatiotemporal clustering. Results 177,171 HCV cases were reported in Henan province between 2005 and 2012. APC modelling showed that the HCV reported rates significantly increased in people aged > 50 years. A moderate increase in HCV reported rates was observed for females aged about 25 years. HCV reported rates increased over the study period. Infection rates were greatest among people born between 1960 and 1980. People born around 1970 had the highest relative risk of HCV infection. Women born between 1960 and 1980 had a five-fold increase in HCV infection rates compared to men, for the same birth cohort. Spatiotemporal mapping showed major clustering of cases in northern Henan, which probably evolved much earlier than other areas in the province. Conclusions Spatiotemporal mapping and APC methods are useful to help delineate the evolution of the HCV epidemic. Birth cohort should be part of the criteria screening programmes for HCV in order to identify those at highest risk of infection and unaware of their status. As Henan is unique in the transmission route for HCV, these methods should be used in other high burden provinces to help identify subpopulations at risk. PMID:26075599

    The incidence of congenital cytomegalovirus (CMV) disease is dependent on the rate of virus acquisition by susceptible women in temporal proximity to pregnancy. Information about serostatus may help to identify high-risk groups and target interventions. Each year from 1991 to 2000, cord blood specimens (surrogates for maternal serum) from 100 consecutive deliveries were obtained at three hospitals. The presence of CMV immunoglobulin G antibody was correlated with demographic data. Overall, 58% of 2992 women were seropositive. After stratification by socioeconomic status (SES), nonwhite race was strongly associated with seropositivity (odds ratio, 3.0; 95% confidence interval [CI], 2.5 to 3.8), and after stratification by race, lower SES also was associated (odds ratio, 2.0; 95% CI, 1.7 to 2.3). There were no trends in seroprevalence over time in any demographic group. However, among white women 21 to 29 years of age, a significant association was found with later birth cohort. Seropositivity ranged from 40% among older, white primigravidas of upper SES to 89% among older, nonwhite, multigravid women of lower SES. These data suggest high rates of CMV transmission among nonwhite women of lower SES. Because these women tended to deliver infants at younger ages, delaying pregnancy even a few years might reduce the incidence of congenital disease. In contrast, most white, upper SES women remain susceptible to primary infection during their childbearing years. Such women born after 1975 may be more likely to reach the childbearing years with CMV immunity as compared with women born before then. PMID:16215924

    Although it is known that the regenerative function of neural stem/progenitor cells (NSPCs) declines with age, causal mechanisms underlying this phenomenon are not understood. Here, we systematically analyze subventricular zone (SVZ) NSPCs, in various groups of rats across the aging spectrum, using in vitro and in vivo histological and behavioral techniques. These studies indicate that although NSPC function continuously declines with advancing age, there is a critical time period during middle age (13-15 months) when a striking reduction in NSPC survival and regeneration (proliferation and neuronal differentiation) occurs. The studies also indicate that this specific temporal pattern of NSPC deterioration is functionally relevant at a behavioral level and correlates with the decreasing expression of the redox-sensitive transcription factor, Nrf2, in the NSPCs. When Nrf2 expression was suppressed in 'young' NSPCs, using short interfering RNAs, the survival and regeneration of the NSPCs was significantly compromised and mirrored 'old' NSPCs. Conversely, Nrf2 overexpression in 'old' NSPCs rendered them similar to 'young' NSPCs, and they showed increased survival and regeneration. Furthermore, examination of newborn Nrf2 knockout (Nrf2 -/-) mice revealed a lower number of SVZ NSPCs in these animals, when compared to wild-type controls. In addition, the proliferative and neurogenic potential of the NSPCs was also compromised in the Nrf2-/- mice. These results identify a novel regulatory role for Nrf2 in NSPC function during aging and have important implications for developing NSPC-based strategies to support healthy aging and to treat age-related neurodegenerative disorders.

    This study was conducted to compare the carcass characteristics and quantity of carcass and non-carcass components of 2- and 3-year-old male camels fattened for either 3 or 6 months. Twelve 2-year-old camels with an average body live weight of 268.5 ± 21.4 kg and twelve 3-year-old camels with an average body live weight of 307.5 ± 29.9 kg were used in a completely randomized design with a 2 × 2 factorial arrangement. For carcass analysis, three camels from each group were selected and slaughtered. The results showed that camel age and fattening period had no significant effect on average daily gain (ADG). Older camels and a longer fattening period resulted in heavier hot and cold carcass weights. Three-year-old camels had a higher dressing percentage compared to 2-year-old camels, regardless of the period of fattening. Analysis of non-carcass components showed that the heaviest component was the hide and 2-year-old camels fattened for 90 days had the greatest weight of hide as percentage of cold carcass weight. Total muscle weight was greater for the 3-year-old camels compared to the 2-year-old ones, regardless of the fattening period, and camels fattened for 180 days had heavier weight than those fattened for 90 days, regardless of age at fattening. However, the greatest weight of total muscle was detected in camels at 2 years of age fattened for 180 days when it was expressed as percentage of carcass weight. The highest and the lowest total fat content as kilogram or as percentage of cold carcass was observed in 3-year-old camels fattened for 180 days and 2-year-old camels fattened for 180 days, respectively. Our results suggested that the best age for slaughtering is 2 years old with the fattening period of 180 days. PMID:27256367

    Wine is one of the world's higher value agricultural products. The present work is centred on Madeira wine, a fine and prestigious example among Portuguese liqueur wines,with the main goal to deepen our understanding of relevant phenomena going on during the winemaking process, in particular during ageing of "Malmsey" Madeira wine. In this paper we present the results obtained from the chemical characterization of how its aroma composition evolves during ageing, and the development of a robust framework for analyzing the identity of aged Madeira wines. An extended ageing period was considered, covering a time frame of twenty years, from which several samples were analyzed in terms of their aromatic composition. The multivariate structure of this chemical information was then processed through multivariate statistical feature extraction techniques such as principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA), in order to identify the relevant patterns corresponding to trends associated with wine ageing. Classification methodologies for age prediction were developed, using data from the lower dimensional sub-spaces obtained after projecting the original data to the latent variable spaces provided by PCA or PLS-DA. Finally, the performance for each classification methodology developed was evaluated according to their error rates using cross-validation methodologies (Leave-One-Out and k-fold Monte Carlo). Results obtained so far show that quite interesting classification performances can indeed be achieved, despite the natural variability present in wine products. These results also provide solid bases which can be used to build up available frameworks which assist quality monitoring and identity assurance tasks. PMID:20103138

    Several lines of evidence indicate that auditory temporal resolution improves over childhood, whereas other data implicate the development of processing efficiency. The present study used the masking period pattern paradigm to examine the maturation of temporal processing in normal-hearing children (4.8 to 10.7 yrs) compared to adults. Thresholds for a brief tone were measured at 6 temporal positions relative to the period of a 5-Hz quasi-square-wave masker envelope, with a 20-dB modulation depth, as well as in 2 steady maskers. The signal was a pure tone at either 1000 or 6500 Hz, and the masker was a band of noise, either spectrally wide or narrow (21.3 and 1.4 equivalent rectangular bandwidths, respectively). Masker modulation improved thresholds more for wide than narrow bandwidths, and adults tended to receive more benefit from modulation than young children. Fits to data for the wide maskers indicated a change in window symmetry with development, reflecting relatively greater backward masking for the youngest listeners. Data for children >6.5 yrs of age appeared more adult-like for the 6500- than the 1000-Hz signal. Differences in temporal window asymmetry with listener age cannot be entirely explained as a consequence of a higher criterion for detection in children, a form of inefficiency. PMID:23464028

    Purpose: To investigate the relationship between dental, chronological, and cervical vertebral maturation growth in the peak growth period, as well as to study the association between the dental calcification phases and the skeletal maturity stages during the same growth period. Methods: Subjects were selected from orthodontic pre-treatment cohorts consisting of 420 subjects where 255 were identified and enrolled into the study, comprising 145 girls and 110 boys. The lateral cephalometric and panoramic radiographs were examined from the archives of the Department of Orthodontics, Aristotle University of Thessaloniki, Greece. Dental age was assessed according to the method of Demirjian, and skeletal maturation according to the Cervical Vertebral Maturation Method. Statistical elaboration included Spearman Brown formula, descriptive statistics, Pearson’s correlation coefficient and regression analysis, paired samples t-test, and Spearman’s rho correlation coefficient. Results: Chronological and dental age showed a high correlation for both gender(r =0.741 for boys, r = 0.770 for girls, p<0.001). The strongest correlation was for the CVM Stage IV for both males (r=0.554) and females (r=0.68). The lowest correlation was for the CVM Stage III in males (r=0.433, p<0.001) and for the CVM Stage II in females (r=0.393, p>0.001). The t-test revealed statistically significant differences between these variables (p<0.001) during the peak period. A statistically significant correlation (p<0.001) between tooth calcification and CVM stages was determined. The second molars showed the highest correlation with CVM stages (CVMS) (r= 0.65 for boys, r = 0.72 for girls). Conclusion: Dental age was more advanced than chronological for both boys and girls for all CVMS. During the peak period these differences were more pronounced. Moreover, all correlations between skeletal and dental stages were statistically significant. The second molars showed the highest correlation whereas the

    Folk calendars are a good source for studying the knowledge and rituals of peoples from distant epochs. The turbulent history of the cultures in the Balkan Peninsula leads to a mixture of calendar traditions - different calendar types and naming systems of the calendar units (months and weekdays). Despite the differences, they share a common astronomical basis and the seasonal structure is of fundamental importance (i.e., dividing the year into two economic seasons - warm and cold). The Old Bulgarian 12-year calendar is also mentioned briefly.

    Background Root canal fillings are intended to prevent microbial proliferation over time in the canal after treatment. Objective To assess biofilm proliferation within the sealer-dentin interfaces of two methacrylate resin-based systems, self-etch (SE) and total-etch (TE), and an epoxy resin-based sealer (EP), aged for up to 6 months. Methods Standardized specimens (n=45) comprising the coronal 5 mm of human roots were filled with the test materials and gutta-percha. Specimens were either not pre-incubated (control; n=9), or incubated in sterile saline for 1 week, 1 month, 3 months or 6 months (n=3/group). Monospecies biofilms of Enterococcus faecalis were grown on the specimens for 7 days in a chemostat-based biofilm fermentor mimicking pathogenic oral conditions. The extent of E. faecalis proliferation within the sealer-dentin interface for each material and incubation period group was assessed using fluorescence microscopy of dihydroethidium-stained specimens. Results TE had less biofilm proliferation than both EP and SE (p<0.01). Deeper biofilm proliferation was detected in SE and EP specimens aged for 1 and 3 months than those aged for 1 week or 6 months (p<0.05). Maximum depth of biofilm penetration was recorded for SE at 1 month (p<0.05). Conclusion Within the test model used, the self-etch and epoxy resin-based sealers were more susceptible to interfacial biofilm proliferation than the total-etch restorative material. This susceptibility diminished after aging the materials’ interfaces for 6 months. PMID:22892745

    Beginning in the mid-1980s and extending into the early 1990s, the United States experienced a wave of increased youth violence and teenage pregnancy. Nevin (2000) proffers a cohort-based explanation that these trends can be attributed to corresponding trends in gasoline lead exposure during the youths' early years. He contends that the increased consumption of adversely impacted their intelligence levels (IQs). This decreased their intellectual ability, resulted in poor decisions made during their teen and young adult years, and in turn, led to disproportionally high level of criminal involvement and unwed pregnancies among this cohort. The present study evaluates Nevin's causal model by testing the connection between trends in lead exposure and youthful problem behavior with age-period-cohort-characteristic (APCC) models. Our research finds no support for this cohort explanation. PMID:15216841

    Two dimensional Difference Gel Electrophoresis (2-D DIGE) and mass spectrometry were applied to investigate the changes in metabolic proteins that occur over a seven day (day 1, 3 and 7) post mortem ageing period in porcine centrifugal exudate from divergent meat quality phenotypes. The objectives of the research were to enhance our understanding of the phenotype (water holding capacity) and search for biomarkers of this economically significant pork quality attribute. Major changes in protein abundance across nine phenotype-by-time conditions were observed. Proteomic patterns were dominated by post mortem ageing timepoint. Using a machine learning algorithm (l1-regularized logistic regression), a model was derived with the ability to discriminate between high drip and low drip phenotypes using a subset of 25 proteins with an accuracy of 63%. Models discriminating between divergent phenotypes with accuracy of 72% and 73% were also derived comparing respectively, high drip plus intermediate phenotype (considered as one phenotype) versus low drip and comparing low drip plus intermediate phenotype (considered as one phenotype) versus high drip. In all comparisons, the general classes of discriminatory proteins identified include metabolic enzymes, stress response, transport and structural proteins. In this research we have enhanced our understanding of the protein related processes underpinning this phenotype and provided strong data to work toward development of protein biomarkers for water holding capacity.

    Birth cohort effects in suicide rates are well established, but to date there is no methodological approach or framework to test the temporal stability of these effects. We use the APC-Detrended (APCD) model to robustly estimate intensity of cohort effects identifying non-linear trends (or ‘detrended’ fluctuations) in suicide rates. The new APC-Hysteresis (APCH) model tests temporal stability of cohort effects. Analysing suicide rates in 25 WHO countries (periods 1970–74 to 2005–09; ages 20–24 to 70–79) with the APCD method, we find that country-specific birth cohort membership plays an important role in suicide rates. Among 25 countries, we detect 12 nations that show deep contrasts among cohort-specific suicide rates including Italy, Australia and the United States. The APCH method shows that cohort fluctuations are not stable across the life course but decline in Spain, France and Australia, whereas they remain stable in Italy, the United Kingdom and the Netherlands. We discuss the Spanish case with elevated suicide mortality of cohorts born 1965–1975 which declines with age, and the opposite case of the United States, where the identified cohort effects of those born around 1960 increase smoothly, but statistically significant across the life course.

    Age is well-known to be a significant factor in both disease pathology and response to treatment, yet the molecular changes that occur with age in humans remain ill-defined. Here, using transcriptome profiling of healthy human male skin, we demonstrate that there is a period of significantly elevated, transcriptome-wide expression changes occurring predominantly in middle age. Both pre and post this period, the transcriptome appears to undergo much smaller, linear changes with increasing age. Functional analysis of the transient changes in middle age suggest a period of heightened metabolic activity and cellular damage associated with NF-kappa-B and TNF signaling pathways. Through meta-analysis we also show the presence of global, tissue independent linear transcriptome changes with age which appear to be regulated by NF-kappa-B. These results suggest that aging in human skin is associated with a critical mid-life period with widespread transcriptome changes, both preceded and proceeded by a relatively steady rate of linear change in the transcriptome. The data provides insight into molecular changes associated with normal aging and will help to better understand the increasingly important pathological changes associated with aging. PMID:27229172

  2. The calendar of the future. A world calendar with leap week

    NASA Astrophysics Data System (ADS)

    Urá, Josef

    There exists a unique perpetual (solar) calendar with leap week that could become the basis for an eventual world calendar reform. Unlike the Universal Calendar considered for such a reform by the UN in 1956, rejected in a vote, it does not interrupt the continuity of weeks, which was the chief objection against this calendar. Except for the mentioned serious chronological defect, the Universal Calendar would otherwise have had many advantages. The leap week concept had been suggested earlier, but was never elaborated properly. Relevant theoretical questions and a suitable form of the calendar based on this concept are discussed. There is also a glimpse of the possible form of our calendar in a very distant future and of a calendar in cosmic space. The new calendar proposed is an optimum compromise for a solar calendar. While preserving advantages of the Universal Calendar, it fulfills all modern requirements: constancy, uniformity, continuity, simplicity and accuracy. With the leap rule derived (with regard to uniform time) an error of one day would occur in the new calendar in an interval longer than 10000 years. It could obtain a global acceptance, because there would be no discordance in the day of the week with respect to other existing calendars having a weekly cycle (such as, e.g., Jewish, Muslim, etc.).

    Wooden calendars are a specific tool for preserving the church calendar in medieval Europe. The Christian symbols are skillfully interwoven with traditional signs, which mark the days of importance for the economic and ritual life in a year. The archaic method of time reckoning has turned into a tool for disseminating and establishing the Christian festival system, and is one of the proofs of the syncretism between the pagan tradition and the new religious ritualism. Bulgarian Christians used such objects until the beginning of the 20th century. The earliest date fixed on a wooden calendar is 1783. These calendars are also called rabosh in Bulgaria. The calendar presented here is based on the Julian (solar) calendar containing the major fixed feasts of the Orthodox Church. It has not been published so far and is kept in a private collection.

    Rhythm has been among the family planning methods endorsed since the start of the National Population Program in the Philippines, but it has not been given as much emphasis as the other methods such as oral contraception (OC), the IUD, and sterilization. For several years, no systematic effort was made to promote the effective use of rhythm. The 1978 Community Outreach Survey (COS) tried to determine the extent to which contraceptive methods were being used in the Outreach Project areas. The project covered 2,000 barangay service points (BSPs) with 1.76 million married couples of reproductive age (MCRA), representing 32% of the estimated total MCRA in the Philippines. The COS findings revealed that, of the total sexually active married women aged 15-49, 48% were using contraceptive methods. Of these, only 11.4% were using modern methods, 20% were using other program methods (rhythm, condom, and combination of rhythm and condom); and 16.7% were using nonprogram methods (withdrawal, abstinence, and others). When used in combination with other methods, rhythm had a monthly continuation rate of 96%; when used alone, 94%. The COS data showed that the rhythm method is practiced by a large number of Filipino couples. With the renewed interest in rhythm, it became imperative for the program to help rhythm acceptors use the method more effectively and thus reduce user failure. There continues to be need for data on the "product image" of rhythm. These include the emotions that come into play in the acceptance or rejection of rhythm, the perceived side effects as well as advantages of the method, the ways women communicate their "safe" and "unsafe" days to their husbands, the manner in which couples prevent sexual contact during "unsafe" days, and the attitude of couples toward abstinence. Among important study findings were the following: couples choose rhythm because it does not disturb the sexual act, has no side effects, and poses no religious objections; 1 of the

    We report periods for 33 members of Blanco 1 as measured from Kilodegree Extremely Little Telescope-South light curves, the first reported rotation periods for this benchmark zero-age-main-sequence open cluster. The distribution of these stars spans from late-A or early-F dwarfs to mid-K with periods ranging from less than a day to ∼8 days. The rotation period distribution has a morphology similar to the coeval Pleiades cluster, suggesting the universal nature of stellar rotation distributions. Employing two different gyrochronology methods, we find an age of 146{sub −14}{sup +13} Myr for the cluster. Using the same techniques, we infer an age of 134{sub −10}{sup +9} Myr for the Pleiades measured from existing literature rotation periods. These rotation-derived ages agree with independently determined cluster ages based on the lithium depletion boundary technique. Additionally, we evaluate different gyrochronology models and quantify levels of agreement between the models and the Blanco 1/Pleiades rotation period distributions, including incorporating the rotation distributions of clusters at ages up to 1.1 Gyr. We find the Skumanich-like spin-down rate sufficiently describes the rotation evolution of stars hotter than the Sun; however, we find cooler stars rotating faster than predicted by a Skumanich law, suggesting a mass dependence in the efficiency of stellar angular momentum loss rate. Finally, we compare the Blanco 1 and Pleiades rotation period distributions to available nonlinear angular momentum evolution models. We find they require a significant mass dependence on the initial rotation rate of solar-type stars to reproduce the observed range of rotation periods at a given stellar mass and are furthermore unable to predict the observed over-density of stars along the upper envelope of the clusters' rotation distributions.

    In this study 58 participants of the liquidation of the consequences of Chernobyl accident in 1986-1987 were investigated. All the patients complain of constant headaches, disorders of memory, general weakness, rapid fatigability, decreased sexual drive, emotional instability etc. The complex (comprehensive) modern methods of investigation were used to carry out the objective assessment of presented complains and of character of the central nervous system damage: complex computer quantitative analysis of mental capacity; analysis of personality traits by using the MMPI test; single photon emission tomography (with the drug of Ceretec); X-ray computer tomography; magnetic resonance computer tomography. The experimental study with examination of primates who were exposured in sum dose 1 Gy (by drop method) was carried out, too. The results of complex investigation of participants of liquidation of Chernobyl accident consequences enable to postulate the formation of premature aging of an organism in these persons. Data of the experimental study of primates irradiated in dose 1 Gy revealed formation of the brain atrophy in the remote period after low dose radiation exposure. PMID:18383710

    We are conducting a multiproxy, regional reconstruction of climate variability during the last two millennia including the Medieval Warm Period (MWP) and Little Ice Age (LIA) in eastern North America. Pollen, benthic foraminifers, ostracodes, and other proxies were analyzed from high-resolution sampling of continuous sedimentary records from lakes, wetlands, and estuaries in Florida, North Carolina, Chesapeake Bay, and Lake Champlain. These records document multi-decadal changes in vegetation, temperature, precipitation, and estuarine salinity across a latitudinal transect. During both the MWP and LIA, decreased precipitation altered plant community composition and distribution in the southeastern United States, and the LIA triggered threshold changes in vegetation that persisted until anthropogenic land-cover change overwhelmed the climate signature. In the mid-Atlantic region, progressively cooler and wetter late Holocene springs culminated in a cool, wet LIA; this trend correlates with observed oceanic changes. Trend analysis of the data suggest that inter-regional correlation of multi-decadal and centennial-scale Holocene climate events will be forthcoming.

    The present study demonstrates the effects of different muscle types and chiller ageing periods on the chemical composition, meat quality parameters, sensory characteristics and volatile compounds of Karean native cattle beed. Longissimus dorsi (LD) and Semitendinosus (ST) muscles aged for 7 days and 28 days were used. Moisture, cooking loss, total collagen and Warner-Bratzler shear force (WBSF) values for the ST were higher than the LD muscle regardless of ageing period (P < 0.05). The LD muscle had higher intramuscular fat (IMF) (P < 0.05). Ageing for 28 days decreased WBSF values whereas it increased thiobarbituric acid of both muscles. Moreover, tenderness, juiciness and flavor scores were significantly higher for the LD muscle at both ageing periods. Increased ageing time improved tenderness of both muscles, and increased juiciness of the LD muscle, whereas there was decreased flavor score of ST muscle (P < 0.05). The majority of the volatile compounds formed from the oxidation of lipids showed differences between the two muscles. Ageing for 28 days increased in the amounts of many volatile compounds; however, the amounts of some important volatile compounds were decreased. These results clearly demonstrate that muscle type and ageing have a potential effect on meat quality, sensory characteristics and volatile profile. PMID:23911040

    To delineate the temporal dynamics between alcohol tax policy changes and related health outcomes, this study examined the age, period and cohort effects on alcohol-related mortality in relation to changes in government alcohol policies. We used the age-period-cohort modeling to analyze retrospective mortality data over 30 years from 1981 to 2010 in a rapidly developed Chinese population, Hong Kong. Alcohol-related mortality from 1) chronic causes, 2) acute causes, 3) all (chronic+acute) causes and 4) causes 100% attributable to alcohol, as defined according to the Alcohol-Related Disease Impact (ARDI) criteria developed by the US Centers for Disease Control and Prevention, were examined. The findings illustrated the possible effects of alcohol policy changes on adult alcohol-related mortality. The age-standardized mortality trends were generally in decline, with fluctuations that coincided with the timing of the alcohol policy changes. The age-period-cohort analyses demonstrated possible temporal dynamics between alcohol policy changes and alcohol-related mortality through the period effects, and also generational impact of alcohol policy changes through the cohort effects. Based on the illustrated association between the dramatic increase of alcohol imports in the mid-1980s and the increased alcohol-related mortality risk of the generations coming of age of majority at that time, attention should be paid to generations coming of drinking age during the 2007–2008 duty reduction.

    physician fee schedule rates could and should be recalculated prospectively in the event that Congress provides the Department with legal authority to revise estimates used to establish the sustainable growth rates (SGR) and for 1998 and 1999 and the NVPS for 1990-1996. The other policy changes concern: the pricing of the technical component for positron emission tomography (PET) scans, Medicare qualifications for clinical nurse specialists, a process to add or delete services to the definition of telehealth, the definition for ZZZ global periods, global period for surface radiation, and an endoscopic base for urology codes. In addition, this rule updates the codes subject to physician self-referral prohibitions. We are expanding the definition of a screening fecal-occult blood test and are modifying our regulations to expand coverage for additional colorectal cancer screening tests through our national coverage determination process. We also make revisions to the sustainable growth rate, the anesthesia conversion factor, and the work values for some gastroenterologic services. We are making these changes to ensure that our payment systems are updated to reflect changes in medical practice and the relative value of services. This final rule also clarifies the enrollment of physical and occupational therapists as therapists in private practice and clarifies the policy regarding services and supplies incident to a physician's professional services. In addition, this final rule discusses physical and occupational therapy payment caps and makes technical changes to the definition of outpatient rehabilitation services. In addition, we are finalizing the calendar year (CY) 2002 interim RVUs and are issuing interim RVUs for new and revised procedure codes for calendar year (CY) 2003. As required by the statute, we are announcing that the physician fee schedule update for CY 2003 is -4.4 percent, the initial estimate of the sustainable growth rate for CY 2003 is 7.6 percent, and

    This study assessed trends in social inequalities in tooth loss in the United Kingdom between 1988 and 2009. Data from 20,126 adults who participated in the latest three national Adult Dental Health Surveys in England, Wales and Northern Ireland were used. Social class was determined using the 6-point Registrar General’s Social Class. Three indicators of tooth loss were analysed; the proportion of edentate people among all adults and the number of teeth and the proportion with functional dentition (defined as having 20+ teeth) among dentate adults. Trends were modelled within an age, period and cohort framework using partial least squares regression (PLSR). Confidence intervals for PLSR estimates were obtained using non-parametric bootstrapping. The Slope and Relative Index of Inequality (SII and RII) were used to quantify social inequalities in tooth loss. Between 1988 and 2009, absolute inequalities in total tooth loss narrowed (SII changed from −28.4% to −15.3%) while relative inequalities widened (RII from 6.21 to 20.9) in the whole population. On the other hand, absolute and relative social inequality in tooth loss remained fairly stable over time among dentate adults. There was an absolute difference of 2.5–2.9 in number of teeth and 22–26% in the proportion with functional dentition between the lowest and highest social classes. In relative terms, the highest social class had 10–11% more teeth and 25–28% higher probability of having functional dentition than the lowest social class. The findings show pervasive inequalities in tooth loss by social class among British adults despite marked improvements in tooth retention in recent years and generations. In the whole adult population, absolute inequalities in tooth loss have narrowed while relative inequalities have increased steadily. Among dentate adults, absolute and relative inequalities in number of teeth and proportion of people with functional dentition have remained significant but

    The Chinese calendar is a form of luni-solar calendar. The rules in operation today have remained unchanged since almost the very beginning of the last (Qing) dynasty - i. e. as far back as A.D.1645. It is the purpose of this article to explain these rules, particularly with regard to the determination of month numbers and intercalation.

    The Templo Mayor of Tenochtitlan was the principal symbol of political power and religious control of the Mexicas. Its orientation was chosen according to ancestral calendrical traditions that considered the Mesoamerican calendar as a sacred concern. The solar alignments incorporated into this emblematic building symbolized moments that divided the solar year according to basic properties of the Mesoamerican calendar.

    New crop calendars are produced for U.S. regions where several years of periodic growth stage observations are available on a CRD basis. Preexisting crop calendars from the LACIE are also collected as are U.S. crop calendars currently being created for the Foreign Commodities Production Forecast project. For the U.S.S.R. and Canada, no new crop calendars are created because no new data are available. Instead, LACIE crop calendars are compared against simulated normal daily temperatures and against the Robertson wheat and Williams barley phenology models run on the simulated normal temperatures. Severe inconsistencies are noted and discussed. For the U.S.S.R., spring and fall planting dates can probably be estimated accurately from satellite or meteorological data. For the starter model problem, the Feyerherm spring wheat model is recommended for spring planted small grains, and the results of an analysis are presented. For fall planted small grains, use of normal planting dates supplemented by spectral observation of an early stage is recommended. The importance of nonmeteorological factors as they pertain to meteorological factors in determining fall planting is discussed. Crop calendar data available at the Johnson Space Center for the U.S., U.S.S.R., Canada, and other countries are inventoried.

    As a result of the conquests of Alexander the Great, the lunisolar Macedonian calendar became the most widely circulated among all the lunisolar Greek calendars. However, despite its spread, two Roman calendars, generally unknown in the scientific community, were developed and used inside Macedonia itself during the Roman occupation of Greece. The older calendar used the so-called ‘Macedonian year’. This system started in 148 BC to emphasize the importance of the victory of the Roman general Quintus Caecilius Metellus Macedonicus against Pseudo-Philippus Andriscus, King of Macedonia. The newer calendrical system, which absorbed the older system, used the ‘Augustian or respectable year’ bearing its name from Octavius Augustus; its starting point was the date of the catalytic victory of Octavius over Marcus Antonius and Cleopatra at Actium (31 BC). The solar Octavian calendar survived until the sixth or seventh century in the Macedonian Territory.

  5. Age estimation of immature human skeletal remains from the diaphyseal length of the long bones in the postnatal period.

    Age at death in immature human skeletal remains has been estimated from the diaphyseal length of the long bones, but few studies have actually been designed specifically for the purpose of age estimation and those which have, show important caveats. This study uses regression and classical calibration to model the relationship between age and diaphyseal length of the six long bones, in a sample of 184 known sex and age individuals (72 females and 112 males), younger than 13 years of age, selected from Portuguese and English skeletal collections. Age estimation models based on classical calibration were obtained for each of the six long bones, and separately for each sex and for the sexes combined, and also for the entire sample and when it is subdivided into two subsamples at the age of 2 years. Comparisons between inverse and classical calibration show there is a systematic bias in age estimations obtained from inverse calibration. In the classical calibration models, the length of the femur provides the most accurate estimates of age. Age estimates are more accurate for the male subsample and for individuals under the age of 2 years. These results and a test of previously published methods caution against inverse calibration as a technique for developing age estimation methods even from the immature skeleton. Age estimation methods developed using cemetery collections of identified human skeletons should not be uncritically applied to present-day populations from the same region since many populations have experienced dramatic secular trends in growth and adult height over the last century.

  6. Aging.

    Park, Dong Choon; Yeo, Seung Geun

    2013-09-01

    Aging is initiated based on genetic and environmental factors that operate from the time of birth of organisms. Aging induces physiological phenomena such as reduction of cell counts, deterioration of tissue proteins, tissue atrophy, a decrease of the metabolic rate, reduction of body fluids, and calcium metabolism abnormalities, with final progression onto pathological aging. Despite the efforts from many researchers, the progression and the mechanisms of aging are not clearly understood yet. Therefore, the authors would like to introduce several theories which have gained attentions among the published theories up to date; genetic program theory, wear-and-tear theory, telomere theory, endocrine theory, DNA damage hypothesis, error catastrophe theory, the rate of living theory, mitochondrial theory, and free radical theory. Although there have been many studies that have tried to prevent aging and prolong life, here we introduce a couple of theories which have been proven more or less; food, exercise, and diet restriction.

  8. The age and origin of the "Younger Dryas climate event" in Greenland ice cores

    230Th/234U and 14C dating of Barbados corals has extended the calibration of 14C years B.P. to calendar years B.P. beyond the 9200 year tree ring series (Bard et al., 1990). This now permits the conversion of 14C chronozones, which delimit major climate shifts in western Europe, to calendar years. The Younger Dryas chronozone, defined as 11,000 to 10,000 14C years B.P., corresponds to 13,000 to 11,700 calendar years B.P. This calibration affects the interpretation of an intensely studied example of the "Younger Dryas climate event," the δ18O anomaly between 1785 and 1793 m in Dye 3 ice core. The end of the δ18O anomaly in Dye 3 ice core has been dated by measurements of 14C in air bubbles (Andree et al., 1984, 1986) and by annual layer counting (Hammer et al., 1986). The older 14C dates fall out of the range of the tree ring calibration series but can now be calibrated to calendar years using the Barbados 230Th/234U calibration. The 14Ccorrected age for the end of the δ18O event is 10,300 ± 400 calendar years B.P. compared to the annual layer counting age of 10,720 ± 150 years B.P. Thus, the "Younger Dryas" event in the Dye 3 ice core ends in the Preboreal chronozone (11,700 to 10,000 calendar years B.P.) and is not correlative with the end of the Younger Dryas event identified in pollen records marking European vegetation changes. The end of the Dye 3 δ18O event is, however, correlative with the end of meltwater pulse IB (Fairbanks, 1989), marking a period of intense deglaciation with meltwater discharge rates exceeding 13,000 km³/yr.

    To describe the temporal trends of breast cancer mortality in East Asia and to better understand the causes of these trends, we analyzed the independent effects of chronological age, time period and birth cohort on breast cancer mortality trends using age-period-cohort (APC) analysis. We chose three main countries in East Asia, namely China, South Korea, and Japan, which have reported death status to the WHO Mortality Database, and used the United States as a comparison population. Our study shows that in general, breast cancer mortality rates in females increased in all three East Asian countries throughout the study period. By APC analysis, we confirmed that there is, in fact, a difference in age-specific mortality rate patterns between the Eastern and the Western countries, which is presumably caused by the two-disease model. While the cause of the decrease from approximately the 1950s generation is still in question, we believe that increasing general awareness and improvements in the health-care system have made a significant contribution to it. Although the age and cohort effects are relatively strong, the period effect may be a more critical factor in the mortality trend, mainly reflecting the increase in exposures to carcinogens and behavioral risk factors.

    2014-01-01

    We provide evidence for multidirectionality, variability, and plasticity in the nature and direction of change in physical health, cognitive functioning, and well-being during the middle years of the life course. The picture of well-being in midlife based on longitudinal data from the Midlife in the United States (MIDUS) study is a more positive one than portrayed in previous cross-sectional studies. We present middle age as a pivotal period in the life course in terms of balancing growth and decline, linking earlier and later periods of life, and bridging younger and older generations. We highlight the role of protective factors and multisystem resilience in mitigating declines. Those in middle age play a central role in the lives of those who are younger and older at home, in the workplace, and in society at large. Thus, a focus on promoting health and well-being in middle age can have a far-reaching impact. PMID:25580043

    The aim of this study was to examine the effects of age, time period, and birth cohorts with dengue fever/dengue hemorrhagic fever (DF/DHF) in Bangkok, Thailand over the period 1981-2000. The age group at greatest risk for DF/DHF was 5-9 years old. The period effect shows a remittent pattern, with significant increases in 1986-1990 and 1996-2000. The birth cohort group showed a significant decreasing trend from the 1961-1965 group to the 1991-1995 group (R2 = 0.7620) with a decreasing rate of 0.1. We concluded that the temporal trend of DF/DHF is decreasing; especially for DHF. PMID:15916090

  18. Assessing the Significance of Cohort and Period Effects in Hierarchical Age-Period-Cohort Models: Applications to Verbal Test Scores and Voter Turnout in U.S. Presidential Elections

    Frenk, Steven M.; Yang, Yang Claire; Land, Kenneth C.

    2014-01-01

    In recently developed hierarchical age-period-cohort (HAPC) models, inferential questions arise: How can one assess or judge the significance of estimates of individual cohort and period effects in such models? And how does one assess the overall statistical significance of the cohort and/or the period effects? Beyond statistical significance is the question of substantive significance. This paper addresses these questions. In the context of empirical applications of linear and generalized linear mixed-model specifications of HAPC models using data on verbal test scores and voter turnout in U.S. presidential elections, respectively, we describe a two-step approach and a set of guidelines for assessing statistical significance.

    In recently developed hierarchical age-period-cohort (HAPC) models, inferential questions arise: How can one assess or judge the significance of estimates of individual cohort and period effects in such models? And how does one assess the overall statistical significance of the cohort and/or the period effects? Beyond statistical significance is the question of substantive significance. This paper addresses these questions. In the context of empirical applications of linear and generalized linear mixed-model specifications of HAPC models using data on verbal test scores and voter turnout in U.S. presidential elections, respectively, we describe a two-step approach and a set of guidelines for assessing statistical significance. The guidelines include assessments of patterns of effects and statistical tests both for the effects of individual cohorts and time periods as well as for entire sets of cohorts and periods. The empirical applications show strong evidence that trends in verbal test scores are primarily cohort driven, while voter turnout is primarily a period phenomenon. PMID:25392566

    The life history calendar is a data-collection tool for obtaining reliable retrospective data about life events. To illustrate the analysis of such data, we compare the model-based probabilistic event history analysis and the model-free data mining method, sequence analysis. In event history analysis, we estimate instead of transition hazards the cumulative prediction probabilities of life events in the entire trajectory. In sequence analysis, we compare several dissimilarity metrics and contrast data-driven and user-defined substitution costs. As an example, we study young adults' transition to adulthood as a sequence of events in three life domains. The events define the multistate event history model and the parallel life domains in multidimensional sequence analysis. The relationship between life trajectories and excess depressive symptoms in middle age is further studied by their joint prediction in the multistate model and by regressing the symptom scores on individual-specific cluster indices. The two approaches complement each other in life course analysis; sequence analysis can effectively find typical and atypical life patterns while event history analysis is needed for causal inquiries.

    Estimating reproductive success for birds with precocial young can be difficult because chicks leave nests soon after hatching and individuals or broods can be difficult to track. Researchers often turn to estimating survival during the prefledging period and, though effective, mark-recapture based approaches are not always feasible due to cost, time, and animal welfare concerns. Using a threatened population of Piping Plovers (Charadrius melodus) that breeds along the Missouri River, we present an approach for estimating chick survival during the prefledging period using long-term (1993-2005), count-based, age-class data. We used a modified catch-curve analysis, and data collected during three 5-day sampling periods near the middle of the breeding season. The approach has several ecological and statistical assumptions and our analyses were designed to minimize the probability of violating those assumptions. For example, limiting the sampling periods to only 5 days gave reasonable assurance that population size was stable during the sampling period. Annual daily survival estimates ranged from 0.825 (SD = 0.03) to 0.931 (0.02) depending on year and sampling period, with these estimates assuming constant survival during the prefledging period and no change in the age structure of the population. The average probability of survival to fledging ranged from 0.126 to 0.188. Our results are similar to other published estimates for this species in similar habitats. This method of estimating chick survival may be useful for a variety of precocial bird species when mark-recapture methods are not feasible and only count-based age class data are available. ?? 2009 Association of Field Ornithologists.

  2. Donepezil Treatment Restores the Ability of Estradiol to Enhance Cognitive Performance in Aged Rats: Evidence for the Cholinergic Basis of the Critical Period Hypothesis

    Recent studies suggest that the ability of estradiol to enhance cognitive performance diminishes with age and/or time following loss of ovarian function. We hypothesize that this is due, in part, to a decrease in basal forebrain cholinergic function. This study tested whether donepezil, a cholinesterase inhibitor, could restore estradiol effects on cognitive performance in aged rats that had been ovariectomized as young adults. Rats were ovariectomized at 3 months of age, and then trained on a delayed matching to position (DMP) T-maze task, followed by a configural association (CA) operant condition task, beginning at 12–17 or 22–27 months of age. Three weeks prior to testing, rats started to receive either donepezil or vehicle. After one week, half of each group also began receiving estradiol. Acclimation and testing began seven days later and treatment continued throughout testing. Estradiol alone significantly enhanced DMP acquisition in middle-aged rats, but not in aged rats. Donepezil alone had no effect on DMP acquisition in either age group; however, donepezil treatment restored the ability of estradiol to enhance DMP acquisition in aged rats. This effect was due largely to a reduction in the predisposition to adopt a persistent turn strategy during acquisition. These same treatments did not affect acquisition of the CA task in middle-aged rats, but did have small but significant effects on response time in aged rats. The data are consistent with the idea that estrogen effects on cognitive performance are task specific, and that deficits in basal forebrain cholinergic function are responsible for the loss of estradiol effect on DMP acquisition in aged ovariectomized rats. In addition, the data suggest that enhancing cholinergic function pharmacologically can restore the ability of estradiol to enhance acquisition of the DMP task in very old rats following long periods of hormone deprivation. Whether donepezil has similar restorative effects on other

    Until now celestial mechanicists have not been able to calculate an astronomical expiration date for the Gregorian Calendar. Why? Because one still has difficulties with the long-term prediction of the duration of the average day d, the average synodical month msyn and the average tropical year atrop. But at least the question can be put clearly now. From the calendar equations of the Gregorian Calendar [1] one obtains a domain, in which the values of atrop/d and msyn/d should remain. This domain is called th e leap-parameter trapezoid and will be presented. [1] Lichtenberg, H., and Richter, P.H., Calendars in the Gregorian Spirit, Poster-Abstract, this vol., p. 95

    This study aimed to describe past time trends of the prevalence of former smokers in Italy and to estimate prevalence projections using a Bayesian approach. An age-period-cohort (APC) analysis has been carried out in order to investigate the effect of the age, period and birth cohort on the prevalence of former smokers during 1980-2009. A Bayesian APC model with an autoregressive structure for the age, period and cohort parameters has been used to estimate future trends. Results showed that awareness of harm from smoking occurred at younger ages with each advancing cohort, and that women were more likely to attempt to stop smoking during pregnancies and breastfeeding, whereas men attempted to quit only when smoking-related diseases became evident. Projections of future trend recorded a further increase in the number of former smokers in future decades, showing an estimate of the "end of smoking" around years 2060 and 2055 in men and women, respectively. The application of the APC analysis to study the prevalence of former smokers turned out to be a useful method for the evaluation of past smoking trends, reflecting the effects of tobacco control policies on time and generations, and to make projections of future trend.

    Background The impact of screening mammography on breast cancer incidence is difficult to disentangle from cohort- and age-related effects on incidence. Methods We developed an age-period-cohort model of ductal carcinoma in situ (DCIS) and invasive breast cancer incidence in U.S. females using cancer registry data. Five functions were included in the model to estimate stage-specific effects for age, premenopausal birth cohorts, postmenopausal birth cohorts, period (for all years of diagnosis), and a mammography period effect limited to women aged ≥40 years after 1982. Incidence with and without the mammography period effect was calculated. Results More recent birth cohorts have elevated underlying risk compared to earlier cohorts for both pre- and postmenopausal women. Comparing models with and without the mammography period effect showed that overall breast cancer incidence would have been 23.1% lower in the absence of mammography in 2010 (95% CI 18.8, 27.4), including 14.7% (9.5, 19.3) lower for invasive breast cancer and 54.5% (47.4, 59.6) lower for DCIS. Incidence of distant-staged breast cancer in 2010 would have been 29.0% (13.1, 48.1) greater in the absence of mammography screening. Conclusions Mammography contributes to markedly elevated rates of DCIS and early stage invasive cancers, but also contributes to substantial reductions in the incidence of metastatic breast cancer. Impact Mammography is an important tool for reducing the burden of breast cancer, but future work is needed to identify risk factors accounting for increasing underlying incidence and to distinguish between indolent and potentially lethal early stage breast cancers that are detected via mammography.

    To characterize the temporal trends of stomach cancer mortality in Eastern Asia and to better interpret the causes of the trends, we performed age, period and cohort analysis (APC analysis) on the mortality rates in Japan, Hong Kong and Singapore during 1950-2004, as well as the rates in the US as a control population. For the APC analysis, Holford's approach was used to avoid the identification problem. Age-standardized mortality rates (ASMR) decreased consistently in all four areas during the observation period in both males and females. Japan had the highest ASMR in both sexes, followed by Singapore, Hong Kong and the US, but the differences in ASMR among the four areas diminished with time. The results of APC analysis suggested that the decreasing mortality rates in Eastern Asia were caused by the combination of decreasing cohort effect since the end of the 1800s and decreasing period effect from the 1950s. The US showed similar results, but its decreases in the period and cohort effect preceded those of Eastern Asia. Possible causes for the decrease in the cohort effect include improvement in the socioeconomic conditions during childhood and a decrease in the prevalence of H. pylori infection, while possible causes for the decrease in the period effect include a decrease in dietary salt intake and improvements in cancer detection and treatment. These findings may help us to predict future changes in the mortality rates of stomach cancer. PMID:21425256

    This study aimed to investigate the demographics, smoking behavior, and benefits of the calendar for a group of participants involved in smoking cessation. The Quit-Calendar, containing 37 question items, was developed to promote smoking cessation. Its use was assessed by the implementation of a study involving 80 participants: 40 in a study group and 40 in a control group. The participants in the study group underwent a routine cessation counseling process with additional Quit-Calendars, whereas those in the control group received routine cessation counseling only. The effectiveness of the Quit-Calendar, duration of quit times (known as survival times), and attitudes to the Quit-Calendar and regular cessation counseling were evaluated via descriptive and analytical statistics. The study found that most participants were male, aged between 30 and 41, and had completed primary to senior high school education. The members of the control group had a significantly higher intention to quit smoking compared to those in the study group (X = 4.20 and 3.35, respectively; p < 0.001). Survival times were measured at days 14 and 60. The results indicated that there were significant differences between the study and control groups on these specific days (p = 0.002 and 0.003, respectively). PMID:26513917

    Observations of the frequency dependence of the global brightness temperature of the redshifted 21 cm line of neutral hydrogen may be possible with single dipole experiments. In this paper, we develop a Fisher matrix formalism for calculating the sensitivity of such instruments to the 21 cm signal from reionization and the dark ages. We show that rapid reionization histories with duration {Delta}z < or approx. 2 can be constrained, provided that local foregrounds can be well modeled by low order polynomials. It is then shown that observations in the range {nu}=50-100 MHz can feasibly constrain the Ly{alpha} and x-ray emissivity of the first stars forming at z{approx}15-25, provided that systematic temperature residuals can be controlled to less than 1 mK. Finally, we demonstrate the difficulty of detecting the 21 cm signal from the dark ages before star formation.

    This report presents the test results of a special calendar-life test conducted on 18650-size, prototype, lithium-ion battery cells developed to establish a baseline chemistry and performance for the Advanced Technology Development Program. As part of electrical performance testing, a new calendar-life test protocol was used. The test consisted of a once-per-day discharge and charge pulse designed to have minimal impact on the cell yet establish the performance of the cell over a period of time such that the calendar life of the cell could be determined. The calendar life test matrix included two states of charge (i.e., 60 and 80%) and four temperatures (40, 50, 60, and 70°C). Discharge and regen resistances were calculated from the test data. Results indicate that both discharge and regen resistance increased nonlinearly as a function of the test time. The magnitude of the discharge and regen resistance depended on the temperature and state of charge at which the test was conducted. The calculated discharge and regen resistances were then used to develop empirical models that may be useful to predict the calendar life or the cells.

    The aim of this research is to develop a calendar variation model for forecasting retail sales data with the Eid ul-Fitr effect. The proposed model is based on two methods, namely two levels ARIMAX and regression methods. Two levels ARIMAX and regression models are built by using ARIMAX for the first level and regression for the second level. Monthly men's jeans and women's trousers sales in a retail company for the period January 2002 to September 2009 are used as case study. In general, two levels of calendar variation model yields two models, namely the first model to reconstruct the sales pattern that already occurred, and the second model to forecast the effect of increasing sales due to Eid ul-Fitr that affected sales at the same and the previous months. The results show that the proposed two level calendar variation model based on ARIMAX and regression methods yields better forecast compared to the seasonal ARIMA model and Neural Networks.

    Introduction This study aimed to assess the trends in tooth loss among adults with and without diabetes mellitus in the United States and racial/ethnic disparities in tooth loss patterns, and to evaluate trends in tooth loss by age, birth cohorts, and survey periods. Methods Data came from 9 waves of the National Health and Nutrition Examination Survey (NHANES) from 1971 through 2012. The trends in the estimated tooth loss in people with and without diabetes were assessed by age groups, survey periods, and birth cohorts. The analytical sample was 37,609 dentate (ie, with at least 1 permanent tooth) adults aged 25 years or older. We applied hierarchical age-period-cohort cross-classified random-effects models for the trend analysis. Results The estimated number of teeth lost among non-Hispanic blacks with diabetes increased more with age than that among non-Hispanic whites with diabetes (z = 4.05, P < .001) or Mexican Americans with diabetes (z = 4.38, P < .001). During 1971–2012, there was a significant decreasing trend in the number of teeth lost among non-Hispanic whites with diabetes (slope = −0.20, P < .001) and non-Hispanic blacks with diabetes (slope = −0.37, P < .001). However, adults with diabetes had about twice the tooth loss as did those without diabetes. Conclusion Substantial differences in tooth loss between adults with and without diabetes and across racial/ethnic groups persisted over time. Appropriate dental care and tooth retention need to be further promoted among adults with diabetes. PMID:26632952

    An association between the dietary intake of polyphenols and human health has been shown in many epidemiological studies. Since beverages are rich sources of polyphenols, we aimed to evaluate the polyphenol intake from beverages in Japanese individuals with a focus on differences according to year, age, gender and season. More than 10,000 Japanese male and female subjects aged 1-99 y old participated in this survey every year from 1996 to 2013, and their beverage consumption and amount of polyphenol intake were calculated. Polyphenol intake from beverages in Japan showed no tendency to increase or decrease over the 18-y period, and the major sources of polyphenols in Japanese daily life were coffee and green tea. Polyphenol intake was larger in participants with higher age up to 59 y old in both male and female subjects. There was a slight difference in polyphenol intake by gender, with adult males consuming more polyphenols than adult females. Polyphenols were consumed slightly more in the winter than the summer, although the seasonal difference in polyphenol intake was not large. Our results suggest that polyphenol intake from beverages is influenced by age rather than gender or season in Japan, and may not have changed over time, at least over the 18-y period beginning in 1996 in Japan.

    Populations of 2 parasitic mites, Dermanyssus hirundinis (Hermann) (63,169 collected individuals) and Ornithonyssus sylviarum (Canestrini et Fanzago) (3,425 collected individuals), in 305 penduline tit, Remiz pendulinus L., nests were studied in 1993 and 1994. The nests were divided into 4 groups: nests without eggs, nests with eggs, nests with nestlings, and nests just after fledging. The average percentage of infested nests increased from the nests without eggs to the nests after fledging (at 20% in both years of investigation), and the increase of mite abundance was exponential. Presence of nestlings in the nests stimulated intensive reproduction of parasitic mites. An increasing infestation intensity in nests was observed during the host breeding period. The 2 mite species exhibited similar age structure patterns in the nests of all the groups and during the entire penduline tit breeding period as well. A decrease in the proportion of adult mites (mainly females) and an increase of nymphs (above all of protonymphs) occurred at the time of fledging and at the end of host breeding period. The percentage of the ovigerous females increased in the individual nests, but decreased during the breeding period of penduline tit. The quantitative parameters of D. hirundinis populations in the highly infested nests depended on the individual nidification and nidobiology of the host, whereas the qualitative parameters (age structure) of these populations depended more on abiotic factors and life strategy of the ectoparasite.

    NASA Astrophysics Data System (ADS)

    Ben-Dov, Jonathan

    A corpus of ca. 20 calendrical texts dated mostly to the first century BCE was found among the Dead Sea scrolls. These documents attest to a year of 364 days, which was adopted from earlier Jewish Pseudepigrapha like the Books of Enoch and Jubilees. The 364-day year was the main time frame used by the sectarian community represented in the scrolls. It is not a solar year, as often stated, but rather a schematic-sabbatical year. Its main characteristic in the DSS is the absorption of many various calendrical frameworks. The 364-day calendar tradition is strongly based on the calculation of full creational weeks and of weeks of years (Shemitah). It incorporates the service cycles of the 24 priestly families in the temple, while in addition, it encompasses an additional cycle of lunar phenomena. This cycle is related to the Mesopotamian concept of "the Lunar Three". Finally, an awareness of the cycle of the Jubilee (49 years) produced a megacycle of 294 years. It remains unknown how and whether at all the 364-day year was intercalated to fit the tropical year of 365.25 days approximately.

  18. Some remarks on the calendar of Coligny

    Gropp, Harald

    The calendar plate of Coligny was found in Coligny (Dept. Ain), north of Bourg-en-Bresse, in 1897, together with a bronze statue of (probably) Mars. Today the calendar can be seen in Lyon in the Musee de la civilization gallo-romaine. The plate of 148cm times 90cm was broken into many pieces. 153 of these fragments were found which is estimated to be about 45 percent of the whole area. These fragments contain inscriptions in Gaulish, written in Latin script. The calendar describes 5 years or 62 months of 1832 days; 60 regular months and 2 intercalary months. There are 6 complete months of 30 days, 5 months of 29 days, and one month (Eqvos) having between 28 and 30 days depending on the year within the 5-year cycle. All the months are divided into 2 fortnights of 15 days or 15 days for the first fortnight and 14 days for the second one. The 2 intercalary months have 30 days each. Until recently the calendar has not become widely known among the general public, even not among astronomers or historians of science. The calendar is well known among language scientists, in particular among celtologists. In 1897 it was the first text in the Gaulish language known again, and is still the longest text in Gaulish. This language died out long ago. It was probably not only spoken in France, Switzerland, and Northern Italy, but also in other parts of Central Europe. The calendar was probably used in the first century BC until the Roman conquest of Gaul. After many linguistic investigations during the 20th century the calendar has been discussed also by mathematically and astronomically oriented scientists in several papers in Astronomie et sciences humaines after 1986 and in 3 recent books.

    Calendaricities, or the occurrence of weather anomalies on fixed calendar dates, are investigated for the Eastern Mediterranean (EM). The anomalies discussed here are the maxima and minima in the frequency of occurrence of the EM synoptic systems bearing rainfall. Those are mostly the Winter Lows passing over Cyprus en route eastward of the Ionian Sea where they are generated in situ or come to from N. Italy. The Winter Lows produce the rainfall over the central and northern EM areas, including Cyprus, Israel, Lebanon, NW Syria, W. Jordan. The southern EM areas, i.e. S. Israel and NE Egypt, get rainfall followed by floods due to the Winter Lows as well, and in addition, due to a small proportion of the mostly dry Red Sea Troughs that occasionally turn out to cause heavy rainfall. The analysis of the daily resolved data based on the NCEP/NCAR reanalysis is carried out. A comparison of two 28-yr periods, 1948-1975 and 1976-2003, different in global climatology, showed their similarity in the timing of peaks in EM cyclonic activity. The winter was found to have five maxima of cyclonic activity, centered on early February and nearly bell-shaped over their magnitudes. This supports the earlier hypotheses of multimodality in the EM rainfall. The Red Sea Troughs have their main peak of occurrence in the late October - early November, and their small rain-bearing proportion falls as well on this period of a year.

    ABSTRACT: Objective: Most infants become settled at night by 3 months of age, whereas infants not settled by 5 months are likely to have long-term sleep-waking problems. We assessed whether normal infant development in the first 3 months involves increasing sleep-period length or the ability to resettle autonomously after waking in the night. Methods: One hundred one infants were assessed at 5 weeks and 3 months of age using nighttime infrared video recordings and parental questionnaires. Results: The clearest development was in sleep length; 45% of infants slept continuously for ≥5 hours at night at 3 months compared with 10% at 5 weeks. In addition, around a quarter of infants woke and resettled themselves back to sleep in the night at each age. Autonomous resettling at 5 weeks predicted prolonged sleeping at 3 months suggesting it may be a developmental precursor. Infants reported by parents to sleep for a period of 5 hours or more included infants who resettled themselves and those with long sleeps. Three-month olds fed solely breast milk were as likely to self-resettle or have long sleep bouts as infants fed formula or mixed breast and formula milk. Conclusions: Infants are capable of resettling themselves back to sleep in the first 3 months of age; both autonomous resettling and prolonged sleeping are involved in “sleeping through the night” at an early age. Findings indicate the need for physiological studies of how arousal, waking, and resettling develop into sustained sleeping and of how environmental factors support these endogenous and behavioral processes.

    This study examined whether the method of hair cortisol analysis is applicable to orang-utans (Pongo spp.) and can help to advance the objective monitoring of stress in non-human primates. Specifically, we examined whether fundamental prerequisites for hair cortisol analysis are given in orang-utans and, subsequently, whether segmental hair analysis may provide a retrospective calendar of long-term cortisol levels. For this, hair samples were examined from 71 zoo-living orang-utans (38 males, mean age=22.5years; 33 females, mean age=24years) for which detailed records of past living conditions were available. Hair samples were cut from defined body regions and were analyzed either in full length or in segments. Results showed that hair cortisol concentrations (HCC) were unrelated to age or sex of the individual animal. HCC were found to be higher in orang-utans, with perceived long-term stressful periods (mean HCC=43.6±26.5pg/mg, n=13) compared to animals without perceived stressful periods (19.3±5.5pg/mg, n=55, P<0.001). In non-stressed animals, segmental hair analyses revealed that HCC was stable along the hair shaft even when hair reached >40cm. The possibility of obtaining a retrospective calendar of stress-related cortisol changes through hair analysis was further supported by data of three case studies showing close correspondence between the segmental HCC results and keeper reports of stress exposure during the respective time periods. Finally, low within-animal variation in HCC from different body regions (CV%: 14.3) suggested that this method may also be applicable to naturally shed hair, e.g., as found in nests of wild orang-utans and other great apes. Therefore, using HCC may provide an ideal non-invasive tool for both captive management as well as conservation in orang-utans and potentially other great apes. PMID:24239791

    There is significant geomorphologic evidence for the past presence of longitudinally widespread, latitudinally zoned deposits composed of ice-rich material at the northern and southern mid latitudes on Mars (lobate debris aprons, lineated valley fill, concentric crater fill, pedestal craters, etc.). Among these features, pedestal craters (Pd) are impact craters interpreted to have produced a protective layer on top of decameters-thick ice deposits now missing in intercrater regions. The time during which these various deposits were present is still highly debated. To address this question we have analyzed the distribution and characteristics of pedestal craters; here, we use a population of 2287 pedestal craters (Pd) to derive a crater retention age for the entire population, obtaining a minimum timescale of formation of ~90 Myr. Given that the ice-rich deposit has not been continuously present for this duration, the timescale of formation is necessarily longer than ~100 Myr. We then compiled impact crater size-frequency distribution dates for 50 individual pedestal craters in both hemispheres to further assess the frequency distribution of individual ages. We calculated pedestal crater ages that ranged from ~1 Myr to ~3.6 Gyr, with a median of ~140 Myr. In addition, 70% of the pedestal ages are less than 250 Myr. During the 150 Myr period between 25 Ma and 175 Ma, we found at least one pedestal age every 15 Myr. This suggests that the ice-rich paleodeposit accumulated frequently during that time period. We then applied these results to the relationship between obliquity and latitudinal ice stability to suggest some constraints on the obliquity history of Mars over the past 200 Myr. Atmospheric general circulation models indicate that ice stability over long periods in the mid latitudes is favored by moderate mean obliquities in the ~35° range. Models of spin-axis/orbital parameter evolution predict that the average obliquity of Mars is ~38°. Our data represent

    Introduction Although substantive declines in motor vehicle fatalities 1980–2010 have been observed, declines by position in the vehicle and alcohol involvement have not been well elucidated. Method Analyses of FARS data use the Intrinisic Estimator (IE) to produce estimates of all age, period, and cohort effects simultaneously by position in the car and by alcohol involvement. Results Declines in MVC deaths by position in the car vary for men and women by age and cohort over time. Cohorts born before 1970 had higher risks than those born later. Analyses using proxy indicators of alcohol involvement found highest risks for those aged 16–24. By period, these risks declined more rapidly than non- alcohol related traffic fatalities. Conclusion Changes in risk patterns are consistent with evidence regarding the contributions of new technologies and public policy efforts to reduce fatalities, but gains have not been shared evenly by sex or position in the car. Practical Application Greater attention is needed to reducing deaths among older drivers and pedestrians. Gender differences should be addressed in prevention efforts aimed at reducing MVCs due to alcohol involvement. PMID:25662882

    Italy was the second main asbestos producer in Europe, after the Soviet Union, until the end of the 1980s, and raw asbestos was imported on a large scale until 1992. The Italian pattern of asbestos consumption lags on average about 10 years behind the United States, Australia, the United Kingdom and the Nordic countries. Measures to reduce exposure were introduced in the mid-1970s in some workplaces. In 1986, limitations were imposed on the use of crocidolite and in 1992 asbestos was definitively banned. We have used primary pleural cancer mortality figures (1970-1999) to predict mortality from mesothelioma among Italian men in the next 30 years by age-cohort-period models and by a model based on asbestos consumption figures. The pleural cancer/mesothelioma ratio and mesothelioma misdiagnosis in the past were taken into account in the analysis. Estimated risks of birth cohorts born after 1945 decrease less quickly in Italy than in other Western countries. The findings predict a peak with about 800 mesothelioma annual deaths in the period 2012-2024. Results estimated using age-period-cohort models were similar to those obtained from the asbestos consumption model. PMID:15645436

  6. Astronomy, Community, and Modern Calendar Buildings

    This paper will look at Avon Tyrrell House, a “calendar house” dating from 1891 and an example of nineteenth-century astronomical architecture in England. The paper will suggest that “calendar buildings” may represent a genre of modern astronomical architecture which has, so far, not been studied, were designed to create stronger communities precisely because of their astronomical connections, and indicates scope for further investigation. The paper will contextualize the modern “calendar building” within the tradition of constructing cities and sacred sites as reflections or embodiments of the sky. By creating spaces which were connected to the celestial bodies, it was possible to create human communities which were linked to celestial ones, encouraging social stability and harmony. Such ideas underpinned traditions of the foundation of cities from China, through India, the Middle East, and Mesoamerica.

    An extensive set of accelerated aging tests has been carried out employing a Li-ion high energy 18650 system (2.05 Ah), negative electrode: carbon, positive electrode: Li(NiMnCo)O2). It is manufactured by Sanyo, labeled UR18650E, and is a commercial off-the-shelf product. The tests comprise both calendar life tests at different ambient temperatures and constant cell voltages and cycle life tests operating the cells within several voltage ranges and levels using standard test profiles. In total, 73 cells have been tested. The calendar life test matrix especially investigates the influence of SOC on aging in detail, whereas the cycle life matrix focuses on a detailed analysis of the influence of cycle depth. The study shows significant impact of the staging behavior of the carbon electrode on cycle life. Furthermore a strong influence of the carbon potential on calendar aging has been detected. Observed relations between aging and the different influence factors as well as possible degradation mechanisms are discussed. Analysis of C/4 discharge voltage curves suggests that cycle aging results in different aging processes and changes in material properties compared to calendar aging. Cycling, especially with cycles crossing transitions between voltage plateaus of the carbon electrode seems to destroy the carbon structure.

  16. Newton's Universal Calendar and Discovery of Linear Regression Analysis: Newton's Analysis of Hipparchus' Equinox Observations

    NASA Astrophysics Data System (ADS)

    Belenkiy, Ari

    2007-08-01

    Among the Newtonian manuscripts, owned by the Jewish National and University Library at Jerusalem and known as MS Yahuda 24, there is a proposal for the reform of the Julian and Ecclesiastical calendars, written in three drafts in early 1700. This was Newton's response to the challenge suggested by Continental mathematicians and astronomers, G.W. Leibniz in particular. This calendar, if implemented in England, would have become a formidable rival to the Gregorian calendar. Despite having a different algorithm, its solar part agrees with the latter until 2400 AD and is more precise in the long run, within a period of 5,000 years. Its lunar algorithm is simpler than the Gregorian, but remained incomplete. Though the calendar was buried under a pile of theological papers, were it now to be implemented it would have a glorious future, since it includes the most characteristic features of the Christian, Jewish, and Muslim calendars and can aspire to become the universal calendar. Looking for the best astronomical parameters Newton attempted to compute the length of the tropical year using the ancient equinox observations reported by Hipparchus of Rhodes. Though Newton had a very thin sample of data, he obtained a tropical year only a few seconds longer than the correct length. We show that the reason lies in Newton's application of a technique similar (though not identical) to the modern ordinary least squares method. Newton also had a clear understanding of qualitative variables. Open historic-astronomical problems related to inclination of the Earth's axis of rotation are discussed. In particular, ignorance about the long-range variation in inclination and nutation is likely responsible for the wide variety in the lengths of the tropical year assigned by different 17th century astronomers - the problem that led Newton to Hipparchus.

  17. Why does FGOALS-gl reproduce a weak Medieval Warm Period but a reasonable Little Ice Age and 20th century warming?

    2013-11-01

    To understand the strengths and limitations of a low-resolution version of Flexible Global Ocean-Atmosphere-Land-Sea-ice (FGOALS-gl) to simulate the climate of the last millennium, the energy balance, climate sensitivity and absorption feedback of the model are analyzed. Simulation of last-millennium climate was carried out by driving the model with natural (solar radiation and volcanic eruptions) and anthropogenic (greenhouse gases and aerosols) forcing agents. The model feedback factors for (model sensitivity to) different forcings were calculated. The results show that the system feedback factor is about 2.5 (W m-2) K-1 in the pre-industrial period, while 1.9 (W m-2) K-1 in the industrial era. Thus, the model’s sensitivity to natural forcing is weak, which explains why it reproduces a weak Medieval Warm Period. The relatively reasonable simulation of the Little Ice Age is caused by both the specified radiative forcing and unforced linear cold drift. The model sensitivity in the industrial era is higher than that of the pre-industrial period. A negative net cloud radiative feedback operates during whole-millennial simulation and reduces the model’s sensitivity to specified forcing. The negative net cloud radiative forcing feedback under natural forcing in the period prior to 1850 is due to the underestimation (overestimation) of the response of cloudiness (in-cloud water path). In the industrial era, the strong tropospheric temperature response enlarges the effective radius of ice clouds and reduces the fractional ice content within cloud, resulting in a weak negative net cloud feedback in the industrial period. The water vapor feedback in the industrial era is also stronger than that in the pre-industrial period. Both are in favor of higher model sensitivity and thus a reasonable simulation of the 20th century global warming.

    This study's objective was to investigate healthy aging in older French adults 5 years after a period of daily nutritional-dose supplementation with antioxidant nutrients. The study was based on the double-blind, randomized trial, Supplementation with Antioxidant Vitamins and Minerals (SU.VI.MAX) Study (1994-2002) and the SU.VI.MAX 2 Follow-up Study (2007-2009). During 1994-2002, participants received a daily combination of vitamin C (120 mg), β-carotene (6 mg), vitamin E (30 mg), selenium (100 µg), and zinc (20 mg) or placebo. Healthy aging was assessed in 2007-2009 by using multiple criteria, including the absence of major chronic disease and good physical and cognitive functioning. Data from a subsample of the SU.VI.MAX 2 cohort, initially free of major chronic disease, with a mean age of 65.3 years in 2007-2009 (n = 3,966), were used to calculate relative risks. Supplementation was associated with a greater healthy aging probability among men (relative risk = 1.16, 95% confidence interval: 1.04, 1.29) but not among women (relative risk = 0.98, 95% confidence interval: 0.86, 1.11) or all participants (relative risk = 1.07, 95% confidence interval: 0.99, 1.16). Moreover, exploratory subgroup analyses indicated effect modification by initial serum concentrations of zinc and vitamin C. In conclusion, an adequate supply of antioxidant nutrients (equivalent to quantities provided by a balanced diet rich in fruits and vegetables) may have a beneficial role for healthy aging.

    The effect of gender (entire male, female and castrate), ageing period (2 or 7days) and endpoint temperature (70 or 75°C) on consumer perceptions of cuts from the loin (Musculuslongissimus thoracis et lumborum), silverside (Musculus biceps femoris) and shoulder (Musculus triceps brachii (roast) and Musculus supraspinatus (stir fry)) when roasted or stir fried (all primals) or grilled as steaks (loin only) was investigated. Higher scores for juiciness (P=0.035), flavour (P=0.017), overall liking (P=0.018), quality grade (P=0.026) were obtained from castrates than entire males, with females intermediate. Neither ageing period nor endpoint temperature, as main effects, influenced sensory scores. Loin steaks and silverside roasts obtained lower (P<0.001) scores for all sensory traits except aroma; scores for shoulder cuts were highest (P<0.001). Cooking to 70°C improved (P<0.05) juiciness, flavor and overall liking scores of loin steaks compared with 75°C. Different pathway interventions are required to optimize eating quality of different pork cuts and the cooking methods used to prepare them. PMID:27348320

    The sources of variations that may cause physiological differences between blood serum biochemistry parameters of bulls have not been investigated in detail. Aim of the present study was to establish influence of different periods of the year and the age of breeding bulls on parameters of antioxidative status and oxidative stress in their serum and to correlate these monitored variables. Research was performed on two groups, each comprising 9 Simmental bulls: a younger group (YB) (aged 2-4 years) and older one (OB) (aged 5-10 years). Blood samples for biochemical analyses were collected from jugular vein in cold (CP) and warm periods (WP) of the year. Reduced glutathione (GSH), uric acid (UA), total protein (TP), albumin (ALB), thiobarbituric acid reactive substance (TBARS), and protein carbonyl content (PCC) serum concentration were determined, as well as activities of selenium-dependent glutathione peroxidase (Se-GSH-Px), total superoxide dismutase (TSOD), manganese superoxide dismutase (MnSOD), copper-zinc superoxide dismutase (CuZnSOD) and catalase (CAT). Serum values of SeGSH-Px, MnSOD, UA and TP in OB were significantly higher compared to those in YB during CP of the year. Significantly higher PCC concentration in serum of YB and OB were established in CP of the year than in WP. TBARS serum concentration in YB was significantly higher in comparison to that in OB during CP of the year. It can be concluded that both OB and YB show a great sensitivity to climate condition alterations during CP in comparison to WP of the year and that YB show even greater sensitivity. PMID:27288340

    Background: The importance of the characteristics of anesthesia and postoperative residual curarization (PORC) in the elderly population should be a growing concern in this century. Aims: To investigate the effect of sugammadex on the duration of the recovery from neuromuscular blocking agents and postoperative residual curarization in the young elderly and middle-aged elderly patients who underwent elective laparoscopic cholecystectomy, followed by a train of four (TOF) watch monitorization. Study Design: Prospective clinical trial study. Methods: Sixty patients over the age of 65 with American Society of Anesthesiologists I–III were divided into two groups according to their age (65–74 years old and ≥75 years old). Patients received sugammadex (2.0 mg/kg iv) at the reappearance of the second twitch of the TOF as an agent for reversal of neuromuscular blockage at the end of surgery. Patients were extubated at the time of TOF ≥0.9. The patients’ TOF responses were evaluated with regards to PORC in at the 5th minute and were followed up for one hour in the recovery room. Reintubation was applied for those patients who developed PORC and had peripheric oxygen saturation <90% despite being given 6 L oxygen per min with a face mask. Results: The onset time of neuromuscular blocking agent and time from T2 to achieve TOF ratio 90% (the duration of sugammadex effect) or over were found to be longer in the middle-aged elderly group than in the young elderly group. A statistically significant relationship was found between age and the duration of TOF ratio to reach 0.9 in the same direction. The PORC incidence and rate of reintubation were found to be 1.7% in all patients. Conclusion: In our opinion, it is necessary to remember that the duration of sugammadex effect on the recovery period is prolonged for patients who are aged ≥75 years compared to patients aged between 65–74 years.

  7. [Periodic abstinence: its possibilities].

    PubMed

    1981-05-01

    Experience with family planning mehods requiring periodic sexual abstinence has been varied. During the last decade interest has centered on 2 methods, the cervical mucus and the sympto-thermal, which are based on identifying the onset of the fertile period. During the 1970s, the Australian physicians John and Evelyn Billings developed the cervical mucus method, in which changes in the quanitity and characteristics of cervical mucus are used to determine the moment of ovulation. The sympto-thermal method depends on identification of the slight rise in basal body temperature that occurs in the latter part of the menstrual cycle as well as cervical mucus changes and sometimes the calendar to determine the fertile period. The Catholic Church has been the main proponent of periodic abstinence methods, but since 1973 the World Health Organization has invested US$3.3 million on research in such methods. The Billings method requires differentiating between dry, wet, and very wet mucus in the vagina and between different consistencies of mucus. The method ususally requires 1-3 months for instruction and sexual abstinence is usually recommended for the 1st month. The average number of days of required abstinence was 9 in a study of 66 women and 15-18 in a study of 870 women. Many women with short menstrual cycles do not experience postmenstrual dry days, in which case abstinence may be required as many as 13 days out of 23. 18.8% of users of periodic abstinence methods in 1 North American study became pregnant in the 1st year, but most were using the calendar method. Women who desired to terminate childbearing had only about 1/2 as many failures with periodic abstinence methods as did women wishing to postpone a birth. PMID:12311397

    An 18-year-old male subject who had had his left hemisphere removed at age eight was better than chance at calculating the day of the week upon which dates in the past and future fell. He was able to describe his method of calculation, which relied upon both visual memory and serial calculations. The use of a serial calculation method was supported by evidence that both response time and accuracy were related to the distance in years from the current year. The use of both visual and verbal "working" memory was supported by interference effects from calendar calculations and delayed visual and verbal memory tasks. The case is discussed in terms of theories regarding similar calculation skills in idiot savants. PMID:2009172

    NASA Astrophysics Data System (ADS)

    Matossian, M. K.

    The objective of this paper is to contribute to the decipherment of the Phaistos Disk. The present assumption is that the Disk was a solar calendar. The proposed method is used to recreate the night sky over Crete in the year 1613 B.C., beginning on September 1, and to follow the astral phenomena for a year thereafter. In addition, the figures on the Disk are interpreted by what is known about Bronze Age Cretan culture, especially agriculture. The result was a set of plausible interpretations of most of the icons found on the Disk. The conclusion is that the Phaistos Disk Unknown Script was created primarily to serve as a guide to the timing of agricultural activities and religious rituals.

    Background The World Health Organization and European Centre for Disease Prevention and Control have highlighted the importance of establishing systems to monitor severe influenza. Following the H1N1 (2009) influenza pandemic, a sentinel network of 23 Trusts, the UK Severe Influenza Surveillance System (USISS), was established to monitor hospitalisations due to confirmed seasonal influenza in England. This article presents the results of the first season of operation of USISS in 2010/11. Methodology/Principal Findings A case was defined as a person hospitalised with confirmed influenza of any type. Weekly aggregate numbers of hospitalised influenza cases, broken down by flu type and level of care, were submitted by participating Trusts. Cases in 2010/11 were compared to cases during the 2009 pandemic in hospitals with available surveillance data for both time periods (n = 19). An unexpected resurgence in seasonal A/H1N1 (2009) influenza activity in England was observed in December 2010 with reports of severe disease. Reported cases over the period of 4 October 2010 to 13 February 2011 were mostly due to influenza A/H1N1 (2009). One thousand and seventy-one cases of influenza A/H1N1 (2009) occurred over this period compared to 409 at the same Trusts over the 2009/10 pandemic period (1 April 2009 to 6 January 2010). Median age of influenza A/H1N1 (2009) cases in 2010/11 was 35 years, compared with 20 years during the pandemic (p = <0.0001). Conclusions/Significance The Health Protection Agency successfully established a sentinel surveillance system for severe influenza in 2010/11, detecting a rise in influenza cases mirroring other surveillance indicators. The data indicate an upward shift in the age-distribution of influenza A/H1N1 (2009) during the 2010/11 influenza season as compared to the 2009/10 pandemic. Systems to enable the ongoing surveillance of severe influenza will be a key component in understanding and responding to the evolving epidemiology of

    Yeso sika deer captured in winter around Lake Akan in Hokkaido were reared for 8-10 months at Tokyo University of Agriculture in Abashiri. Six 1-year-old females and males and six 2-year-old or older (adult) females and males were slaughtered and their carcasses were processed. The chemical composition, mineral contents and fatty acid composition of the loin were measured. No marked influence of gender or age was noted in the chemical composition of loin. In the mineral contents, significant differences were noted. The potassium and sulfur contents were lower and the sodium content was higher in adult deer meat (P < 0.05, respectively) and the potassium content was higher in male deer meat (P < 0.05). Arsenic, cadmium or lead were not detected. In the unsaturated fatty acid, a significant interaction was detected (P < 0.05), and it was high in 1-year-old female deer meat and low in 1-year-old male deer meat. Significant gender or age differences were noted only in the mineral contents in the loin of deer reared for a short period after capture. PMID:25186458

    Objectives Neglecting the presence of unobserved heterogeneity in survival analysis models has been showed to potentially lead to underestimating the effect of the covariates included in the analysis. This study aimed to investigate the role of unobserved heterogeneity of frailty on the estimation of mortality differentials from age 50 on by education level. Design Longitudinal mortality follow-up of the census-based Turin population linked with the city registry office. Setting Italian North-Western city of Turin, observation window 1971–2007. Population 391 170 men and 456 216 women followed from age 50. Primary outcome measures Mortality rate ratios obtained from survival analysis regression. Models were estimated with and without the component of unobserved heterogeneity of frailty and controlling for mortality improvement over time from both cohort and period perspectives. Results In the majority of cases, the models without frailty estimated a smaller educational gradient than the models with frailty. Conclusions The results draw the attention of the potential underestimation of the mortality inequalities by socioeconomic levels in survival analysis models when not controlling for unobserved heterogeneity of frailty.

    This study examined if temporal variations in daily cigarette smoking and never smoking among groups with different levels of education fit the pattern proposed by the theory of diffusion of innovations (TDI), while taking into account the separate effects of age, period and birth cohort (APC). Aggregated data from nationally representative interview surveys from Norway from 1976 to 2010 was used to calculate probabilities of smoking using an APC approach in which the period variable was normalized to pick up short term cyclical effects. Results showed that educational differences in smoking over time were more strongly determined by birth cohort membership than variations in smoking behavior across the life course. The probability of daily smoking decreased faster across cohorts among higher compared to lower educated. In contrast, the change in probability of never having smoked across cohorts was similar in the two education groups, but stronger among men compared to women. Moreover, educational differences in both daily and never smoking increased among early cohorts and leveled off among late cohorts. The results emphasizes the importance of birth cohort for social change and are consistent with TDI, which posits that smoking behavior diffuse through the social structure over time. PMID:25131273

    Brain ageing in mice leads to the progressive appearance and expansion of degenerative granular structures frequently referred as "PAS granules" because of their positive staining with periodic acid-Schiff (PAS). PAS granules are present mainly in the hippocampus, although they have also been described in other brain areas such as piriform and entorhinal cortices, and have been observed in other mammals than mice, like rats and monkeys. PAS granules have been identified as a wide range of brain deposits related to numerous neurodegenerative diseases, such as amyloid deposits, neurofibrillary tangles, Lafora bodies, corpora amylacea and polyglucosan bodies, and these identifications have generated controversy and particular theories about them. We have recently reported the presence of a neo-epitope in mice hippocampal PAS granules and the existence of natural IgM auto-antibodies directed against the neo-epitope in the plasma of the animals. The significance of the neo-epitope and the autoantibodies is discussed in this review. Moreover, we observed that the IgM anti-neo-epitope is frequently present as a contaminant in numerous commercial antibodies and is responsible of a considerable amount of false positive immunostainings, which may produce misinterpretations in the identification of the granules. Now that this point has been clarified, this article reviews and reconsiders the nature and physiopathological significance of these degenerative granules. Moreover, we suggest that neo-epitopes may turn into a useful brain-ageing biomarker and that autoimmunity could become a new focus in the study of age-related degenerative processes. PMID:26970374

    Sheep were among the first domesticated animals to appear in Estonia in the late Neolithic and became one of the most widespread livestock species in the region from the Late Bronze Age onwards. However, the origin and historical expansion of local sheep populations in Estonia remain poorly understood. Here, we analysed fragments of the hypervariable D-loop of mitochondrial DNA (mtDNA; 213 bp) and the Y-chromosome SRY gene (130 bp) extracted from 31 archaeological sheep bones dated from approximately 800 BC to 1700 AD. The ancient DNA data of sheep from Estonia were compared with ancient sheep from Finland as well as a set of contemporary sheep breeds from across Eurasia in order to place them in a wider phylogeographical context. The analysis shows that: (i) 24 successfully amplified and analysed mtDNA sequences of ancient sheep cluster into two haplogroups, A and B, of which B is predominant; (ii) four of the ancient mtDNA haplotypes are novel; (iii) higher mtDNA haplotype diversity occurred during the Middle Ages as compared to other periods, a fact concordant with the historical context of expanding international trade during the Middle Ages; (iv) the proportion of rarer haplotypes declined during the expansion of sheep from the Near Eastern domestication centre to the northern European region; (v) three male samples showed the presence of the characteristic northern European haplotype, SNP G-oY1 of the Y-chromosome, and represent the earliest occurrence of this haplotype. Our results provide the first insight into the genetic diversity and phylogeographical background of ancient sheep in Estonia and provide basis for further studies on the temporal fluctuations of ancient sheep populations.

    Centaur Chiron's Calendar is an educational activity incorporated in environmental education which combines the principles of inter-scientific approach with fundamental astronomy conception. It is performed in school as a yearly environmental project. The famous centaur was teaching the hero Jason (and others) navigation based on stellar observation and medicine based on Pelion herbs collected at the right time of the year. Students are guided to discover his method of determination of the right time. The project evolves the creation of a photographic calendar based on collected pictures from the sunset during the various seasons of the year. It is developed in the same region that Chiron lived (Mount Pelion) according to mythology but it can be modified for use in other regions. Sunset positions are recorded daily or weekly and plotted on a wide-angle picture of the western hill crest. Students are then called to predict the date of a given sunset position. Students also record sunset time and duration of the day in order to relate it with the photographic calendar. The activity combines knowledge from various scientific fields such as history, geography and astronomy. Development of practical skills such as accurate observation, photography techniques and digital image processing is a welcomed side effect of this educational activity.

  7. Rotation Periods for Cool Stars in the 4 Gyr old Open Cluster M67, The Solar–Stellar Connection, and the Applicability of Gyrochronology to at least Solar Age

    NASA Astrophysics Data System (ADS)

    Barnes, Sydney A.; Weingrill, Joerg; Fritzewski, Dario; Strassmeier, Klaus G.; Platais, Imants

    2016-05-01

    We report rotation periods for 20 cool (FGK) main sequence member stars of the 4 Gyr-old open cluster M67 (=NGC 2682), obtained by analyzing data from Campaign 5 of the K2 mission with the Kepler Space Telescope. The rotation periods delineate a sequence in the color–period diagram (CPD) of increasing period with redder color. This sequence represents a cross-section at the cluster age of the surface P = P(t, M), suggested in prior work to extend to at least solar age. The current Sun is located marginally (approximately 1σ) above M67 in the CPD, as its relative age leads us to expect, and lies on the P = P(t, M) surface to within measurement precision. We therefore conclude that the solar rotation rate is normal as compared with cluster stars, a fact that strengthens the solar–stellar connection. The agreement between the M67 rotation period measurements and prior predictions further implies that rotation periods, especially when coupled with appropriate supporting work such as spectroscopy, can provide reliable ages via gyrochronology for other similar FGK dwarfs from the early main sequence to solar age and likely until the main sequence turnoff. The M67 rotators have a rotational age of 4.2 Gyr with a standard deviation of 0.7 Gyr, implying that similar field stars can be age-dated to precisions of ∼17%. The rotational age of the M67 cluster as a whole is therefore 4.2 Gyr, but with a lower (averaged) uncertainty of 0.2 Gyr.

    The reasons for the development and collapse of Maya civilization remain controversial and historical events carved on stone monuments throughout this region provide a remarkable source of data about the rise and fall of these complex polities. Use of these records depends on correlating the Maya and European calendars so that they can be compared with climate and environmental datasets. Correlation constants can vary up to 1000 years and remain controversial. We report a series of high-resolution AMS 14C dates on a wooden lintel collected from the Classic Period city of Tikal bearing Maya calendar dates. The radiocarbon dates were calibrated using a Bayesian statistical model and indicate that the dates were carved on the lintel between AD 658-696. This strongly supports the Goodman-Martínez-Thompson (GMT) correlation and the hypothesis that climate change played an important role in the development and demise of this complex civilization.

    The Saptarishis Calendar of ancient India is based on precession of the equinoxes. It employs the tropical zodiac of the Greeks and the precessional rate of Hipparchus. The Saptarishis era has to be determined by naked eye observation of the sky. Currently, the line of reference goes through the stars Dubhe and Merak in the constellation of Ursa Major, touching both of them, and crosses the ecliptic in the sidereal Purvaphalguni Nakshatra of Simha Rashi at a point close to the star 59 Leonis. The angular difference between this 'Saptarishis pointer' and the vernal equinox gives the tropical lunar mansion in which Saptarishis resides at a given point in time.

    NASA Astrophysics Data System (ADS)

    Schaffer, Jeffrey P.

    In the May 10, 1994, issue of Eos, Cesare Emiliani suggested a new calendar, since the current one “singles out an event—the birth of Christ—which has no significance in non-Christian civilizations.” I am neither Christian nor religious, yet I have no problem with the current calendar. However, I do have problems with Emiliani's proposed calendar. First, set at exactly 10,000 B.C., it is tied directly to the birth of Christ, so if Emiliani has tried to select an arbitrary, non-Christian date, he has failed. Perhaps he ought to try 10,000 years before the first year of the Chinese calendar (if that could be precisely established.) After all, there are more Chinese on this planet than Europeans, their civilization and calendar preceded those of the Europeans, and they stand to be the superpower of the next century.

    2014-01-01

    We present the first U-series ages of corals from emergent marine deposits on the Canary Islands. Deposits at + 20 m are 481 ± 39 ka, possibly correlative to marine isotope stage (or MIS) 11, while those at + 12 and + 8 m are 120.5 ± 0.8 ka and 130.2 ± 0.8 ka, respectively, correlative to MIS 5.5. The age, elevations, and uplift rates derived from MIS 5.5 deposits on the Canary Islands allow calculations of hypothetical palaeo-sea levels during the MIS 11 high sea stand. Estimates indicate that the MIS 11 high sea stand likely was at least + 9 m (relative to present sea level) and could have been as high as + 24 m. The most conservative estimates of palaeo-sea level during MIS 11 would require an ice mass loss equivalent to all of the modern Greenland and West Antarctic ice sheets; the more extreme estimates would require additional ice mass loss from the East Antarctic ice sheet. Extralimital southern species of mollusks, found in both MIS 11 and MIS 5.5 deposits on the Canary Islands, imply warmer-than-modern sea surface temperatures during at least a part of MIS 11 and much warmer sea surface temperatures during at least a part of MIS 5.5. Both MIS 11 and MIS 5.5 marine deposits on the Canary Islands contain extralimital northern species of mollusks as well, indicating cooler-than-present waters at times during these interglacial periods. We hypothesize that the co-occurrence of extralimital southern and northern species of marine invertebrates in the fossil record of the Canary Islands reflects its geographic location with respect to major synoptic-scale controls on climate and ocean currents. Previous interglacials may have been characterized by early, insolation-forced warming, along with northward migration of the intertropical convergence zone (ITCZ), accompanied by weakened trade winds and diminished upwelling. This allowed the arrival of extralimital southern taxa from the tropical Senegalese faunal province. During later parts of the MIS 11 and 5

    Bank Indonesia (BI) as the central bank of Republic Indonesiahas a single overarching objective to establish and maintain rupiah stability. This objective could be achieved by monitoring traffic of inflow and outflow money currency. Inflow and outflow are related to stock and distribution of money currency around Indonesia territory. It will effect of economic activities. Economic activities of Indonesia,as one of Moslem country, absolutely related to Islamic Calendar (lunar calendar), that different with Gregorian calendar. This research aims to forecast the inflow and outflow money currency of Representative Office (RO) of BI Semarang Central Java region. The results of the analysis shows that the characteristics of inflow and outflow money currency influenced by the effects of the calendar variations, that is the day of Eid al-Fitr (moslem holyday) as well as seasonal patterns. In addition, the period of a certain week during Eid al-Fitr also affect the increase of inflow and outflow money currency. The best model based on the value of the smallestRoot Mean Square Error (RMSE) for inflow data is ARIMA model. While the best model for predicting the outflow data in RO of BI Semarang is ARIMAX model or Time Series Regression, because both of them have the same model. The results forecast in a period of 2015 shows an increase of inflow money currency happened in August, while the increase in outflow money currency happened in July.

    This paper demonstrates the potential of using Web search volumes for generating crop specific planting and harvesting dates in the USA integrating climatic, social and technological factors affecting crop calendars. Using Google Insights for Search, clear peaks in volume occur at times of planting and harvest at the national level, which were used to derive corn specific planting and harvesting dates at a weekly resolution. Disaggregated to state level, search volumes for corn planting generally are in agreement with planting dates from a global crop calendar dataset. However, harvest dates were less discriminatory at the state level, indicating that peaks in search volume may be blurred by broader searches on harvest as a time of cultural events. The timing of other agricultural activities such as purchase of seed and response to weed and pest infestation was also investigated. These results highlight the future potential of using Web search data to derive planting dates in countries where the data are sparse or unreliable, once sufficient search volumes are realized, as well as the potential for monitoring in real time the response of farmers to climate change over the coming decades. Other potential applications of search volume data of relevance to agronomy are also discussed.

    Patients with memory disorders have severely restricted learning and memory. For instance, patients with anterograde amnesia can learn motor procedures as well as retaining some restricted ability to learn new words and factual information. However, such learning is inflexible and frequently inaccessible to conscious awareness. Here we present a case of patient AC596, a 25-year old male with severe episodic memory impairments, presumably due to anoxia during a preterm birth. In contrast to his poor episodic memory, he exhibits savant-like memory for calendar information that can be flexibly accessed by day, month, and year cues. He also has the ability to recollect the exact date of a wide range of personal experiences over the past 20 years. The patient appears to supplement his generally poor episodic memory by using memorized calendar information as a retrieval cue for autobiographical events. These findings indicate that islands of preserved memory functioning, such as a highly developed semantic memory system, can exist in individuals with severely impaired episodic memory systems. In this particular case, our patient’s memory for dates far outstripped that of normal individuals and served as a keen retrieval cue, allowing him to access information that was otherwise unavailable.

  9. Calendar-effects and temperature-impacts in migratory waterbirds at three tropical Indian wetlands

    2012-08-01

    We analysed the relationships of the arrival and departure, abundance and assemblages of 13 migratory waterbirds in three tropical wintering abodes, with calendar-effect and air temperature. The birds arrive at the wetlands in October-November and most of the long-distance migrants spent 4-5 months, while the short-distance local migrants stayed there for almost 7 months. Much like the onset of autumn migration from the breeding ground, the period of arrival at these wintering abodes was influenced by photoperiod confounded with other calendar-date effects. There was a significant negative relationship between this variable and the abundance of all the 13 species and their maximum abundances corresponded closely with the shortest day length. The temperature tended to fine-tune the migration schedule. The migration phenology and abundances of all the species exhibited strong negative correlations with this environmental variable and maximum abundances were observed during the middle of January, which experienced the coldest temperatures of the region. The long-distance migrants left the wetlands earlier than the short-distance local migrants. Both the photoperiod confounded with other calendar-date effects and temperature affected dissolved oxygen concentration and phytoplanktonic productivity of the wetlands, which influenced the waterbirds. Dissolved oxygen concentration affected the abundances of most of these waterbirds probably through its impact on their food resources. Phytoplanktonic productivity might also influence overall food supply to the waterbirds.

  10. Non-algorithmic access to calendar information in a calendar calculator with autism.

    2006-02-01

    The possible use of a calendar algorithm was assessed in DBC, an autistic "savant" of normal measured intelligence. Testing of all the dates in a year revealed a random distribution of errors. Re-testing DBC on the same dates one year later shows that his errors were not stable across time. Finally, DBC was able to answer "reversed" questions that cannot be solved by a classical algorithm. These findings favor a non-algorithmic retrieval of calendar information. It is proposed that multidirectional, non-hierarchical retrieval of information, and solving problems in a non-algorithmic way, are involved in savant performances. The possible role of a functional rededication of low-level perceptual systems to the processing of symbolic information in savants is discussed. PMID:16453069

    Lack of competence teachers to educate basic science astronomy and space science in Indonesia implies that knowledge of astronomy and space science will be transmitted to the young generation improperly. Priority in curriculum of basic science include only small amount of general astronomy and public perception that astronomy is less importance than basic science both are disadvantage for developing astronomical community in Indonesia a country with more than 230 million people. Muslim community in Indonesia has a tradition to use a lunar calendar and a tradition to determine the first day the important month Ramadhan Syawal and Dzulhijjah. Recent disputeof determining the first day of the three important month partly due to the lack of knowledge the first visibility of lunar crescent. The challenge of introducing astronomy on wider community with less background on astronomical education will be discussed in this paper

    The last interglacial period has a timing and duration that can be estimated from U-series dating of emergent, coral-bearing deposits on tectonically stable coastlines. High-precision dating from Bermuda, the Bahamas, Hawaii, and Australia suggests that the last interglacial period had a sea level at least as high as present from ???128,000 to 116,000 yr B.P. Sea level reached a near-present level more quickly after the close of the penultimate glacial period than at the close of the last glacial period and the duration of high sea level is longer than that implied by the deep-sea record. ?? 2002 University of Washington.

  18. Age-Based Methods to Explore Time-Related Variables in Occupational Epidemiology Studies

    Although age is recognized as the strongest predictor of mortality in chronic disease epidemiology, a calendar-based approach is often employed when evaluating time-related variables. An age-based analysis file, created by determining the value of each time-dependent variable for each age that a cohort member is followed, provides a clear definition of age at exposure and allows development of diverse analytic models. To demonstrate methods, the relationship between cancer mortality and external radiation was analyzed with Poisson regression for 14,095 Oak Ridge National Laboratory workers. Based on previous analysis of this cohort, a model with ten-year lagged cumulative radiation doses partitioned by receipt before (dose-young) or after (dose-old) age 45 was examined. Dose-response estimates were similar to calendar-year-based results with elevated risk for dose-old, but not when film badge readings were weekly before 1957. Complementary results showed increasing risk with older hire ages and earlier birth cohorts, since workers hired after age 45 were born before 1915, and dose-young and dose-old were distributed differently by birth cohorts. Risks were generally higher for smokingrelated than non-smoking-related cancers. It was difficult to single out specific variables associated with elevated cancer mortality because of: (1) birth cohort differences in hire age and mortality experience completeness, and (2) time-period differences in working conditions, dose potential, and exposure assessment. This research demonstrated the utility and versatility of the age-based approach.

    This article is about Saharan calendars from precolonial times to the present. It shows that multiple calendar use has been a constant feature throughout the centuries, that the distinction between indigenous and imported has little meaning in this region of long-standing cultural exchange, and that many Saharan communities still simultaneously use differing official state, literate specialist, and local popular calendars. Social and political explanations of calendar pluralism are presented, contrasting the center view whereby calendars constitute a means of social control and the periphery view whereby communities may affirm their cultural autonomy through particular calendar choices.

    2015-01-01

    The treatment approach to patients 80 years of age and older with gastroesophageal cancer at Baylor Scott and White in Temple, Texas, has historically favored conservative measures in the form of palliation and observation. To evaluate this trend in practice, the administered treatments and subsequent patient outcomes of this group were retrospectively reviewed. The study group included all patients 80 years of age and older with a diagnosis of gastroesophageal cancer seen at our facility between 1991 and 2010. Of the 117 cases, 49% received none of the available treatment modalities. The median overall survival (OS) of patients who received treatment, however, was significantly longer than the OS of those who did not, regardless of modality. Specifically, surgical intervention offered an almost double median OS compared with no therapy (6.8 vs. 3.9 months, respectively; P = 0.02); chemotherapy, an almost 4-fold OS benefit (14.8 vs. 3.9 months; P = 0.03); and radiation therapy, a >3-fold OS benefit (11.1 vs. 3.5 months; P = 0.04). These results further substantiate chronological age as an inaccurate predictor of treatment benefit, and age alone should not dictate the administration or withholding of available treatment options.

    To evaluate the role of the razor clam Ensis directus in Dutch coastal waters, understanding its population dynamics is important. As such, the age structure of the population forms a key parameter. Accurate age determination in bivalve shells is not always straightforward due to the difficulty of interpreting externally visible growth lines. In the present paper, we aimed at validating the seasonality in growth line formation using visual techniques in combination with stable oxygen and carbon isotope analyses (δ18O and δ13C). High δ18O values in the shell coincided with growth marks on the external surface of the valve and in acetate peels of the shell's cross section. Most shell δ18O samples were assigned to the months from June to September. From November to March no samples were retrieved, indicating that the shell did not grow. The lowest reconstructed temperature (6.3 °C) suggests that ~ 6 °C may be the threshold temperature for growth. Nevertheless, most of the reconstructed values fell above 14.5 °C, indicating that growth occurred mainly in the summer at relatively high temperatures. Shell δ13C profiles followed a more or less seasonal cycle, but no direct relationship could be made between δ13C values and annual growth lines. Although counting external annual growth lines led to a correct estimation of age and consequently of growth rates, we recommend analysing acetate peels of cross sections to support the distinction between annual lines and disturbance lines.

  9. The horizontal-branch stars in globular clusters. I - The period-shift effect, the luminosity of the horizontal branch, and the age-metallicity relation

    Synthetic models of the horizontal branches in globular clusters are constructed from a grid of the standard horizontal branch evolutionary tracks. The models are used to study the period shifts at constant T(eff) between RR Lyrae variables in globular clusters of different metallicities and the variation in horizontal-branch luminosity with the Fe/H ratio. The results suggest that the observed differences in the mean periods of the ab variables and the fraction of c-type variables between the two Oosterhoff groups are caused by a difference in the mean luminosity of the ab variables of about 0.18 bolometric mass and by the uneven distribution of variables across the instability strip in the group II clusters.

    Radiocarbon measurements from foraminifera in marine sediment cores are widely used to constrain age models and the timing of paleoceanographic events, as well as past changes in ocean circulation and carbon cycling. However, the use of radiocarbon for both dating and palaeoceanographic applications is limited in sediment cores by a lack of knowledge about the surface ocean radiocarbon reservoir age and how it varies in both space and time. Typically, to convert a planktic radiocarbon age into a calendar age, an assumed constant reservoir age is applied. However, there is mounting evidence to suggest that this assumption of constant reservoir age through time is an oversimplification, particularly for the high latitude oceans during the cold climates of the last glacial and deglacial periods. Here we present new high-resolution radiocarbon records together with tephra tie points and 230-thorium (230Th) constrained sedimentation rates to improve estimates of radiocarbon reservoir age in the Northeast Atlantic Ocean. In addition we will explore the impact of the new reservoir ages for both the age models of the cores studied, as well as the palaeoceanographic implications of these reservoir age changes during intervals of rapid climate change over the past 40,000 years.

  11. Mishmarot Calendars from Qumran Cave 4: Congruence and Divergence

    Snyder, George, Jr.

    1997-09-01

    This study examines the calendar observed by the sect whose writings have been found in the caves of the Judean desert. Chapter I introduces the Qumran calendar as an outgrowth of the 364-day pseudo-solar year described in the astronomical chapters of 1 Enoch and defended in the Book of Jubilees. The Temple Scroll completes a calendric foundation by making canonical several summer harvest festivals not found in the Hebrew Scriptures. Chapters II through VII detail the eight mishmarot manuscripts, providing text, translation, and analysis toward understanding the fully developed calendric structure. These investigations manifest arguments that establish the beginning of the sect's lunar month at the full moon, present coordination methodologies that balance the 364-day solar year with the 354-day lunar one, and reveal two different arrangements of the festival cycle. The Conclusion gathers under the heads of Enoch and Jubilees evidence to propose two sectarian calendar traditions and brings forward other texts which could be similarly categorized. Three appendices and a glossary support the discussion from non-mishmarot calendars and presenting an eclectic six-year calendar in full detail.

    The general decline of science which took place in the first half of the 18th century was a cause of a huge quantity of calendars editing. Calendars substituted for the former scientific literature. Up to 1763 over 800 calendars appeared. A half of them was published in Cracov. Those calendars differed from the contemporary ones. Apart from dates, they included not only basic information in history, geography agriculture economy but, not seldom, medicine as well. Most often they were written by university professors with a few physicians among them. Obviously, the level of the presented medical knowledge was very low. There wenadductions to astrology, wizardry and Provinience. But some diagnoses and therapeutic advice being a kind of doctor's manual, useful to so-called domestic medicine are still worth of the attention. First of all, phytotherapy chapter based on the folk empiricism, was the most rational. Thought 18th century calendars did not have much in common with real medicine, they make an interesting source to search for history of the Polish medicine of the Saxon times. PMID:9245110

    Background While researchers have identified factors that contribute to youth violence, less is known about the details of violent incidents. In addition, substance use has been linked to youth violence; however, little is known about actual substance use on days in which violence occurs. Objective This study examined reasons for peer violence and the association between substance use and violence using daily calendar-based analyses among at-risk urban youth. Methods Data were collected from Emergency Department (ED) patients (ages 14–24; n=599; 59% male, 65% African American) who screened positive for substance use in the past 6 months. Daily data regarding past 30-day substance use and violence and reasons for violent incidents were obtained via semi-structured interviews. Multi-level multinomial regression models were conducted to test the associations between substance use and peer violence incidents (i.e., none, moderate and severe). Results Conflict over ‘personal belongings’ was a common reason for violence among males; ‘jealousy’/’rumors’ were common reasons among females. Moderate victimization was more likely to be reported on days in which participants reported alcohol and cocaine use. Severe victimization was more likely to be reported on days in which participants reported alcohol use. Moderate or severe aggression was more likely to be reported on days in which participants reported alcohol and non-medical sedative use. Conclusions Results suggest that youth violence prevention that addresses differential reasons for violence among males and females as well as substance use would be beneficial. PMID:25493643

    This report gives the results of the environmental activities and monitoring programs at the Princeton Plasma Physics Laboratory (PPPL) for Calendar Year 1989 (CY89). The report is prepared to provide the US Department of Energy (DOE) and the public with information on the level of radioactive and nonradioactive pollutants, if any, added to the environment as a result of PPPL operations. The objective of the environmental report is to document evidence that DOE facility environmental protection programs adequately protect the environment and the public health. During CY89, there were no accidents, incidents, or occurrences that had a significant impact on PPPL facilities or program operations. The accidental overfilling of an underground storage tank (UST) during 1988, along with the discovery of residual hydrocarbons in the soil of an area used for unloading fuel oil trucks over the last 30 years, has the potential for a minor environmental impact and has resulted in a costly clean up in this area. Surface water analyses for both radioactive and nonradioactive pollutants have shown nothing above normally expected background values. Ambient tritium levels at less than 100 pCi/liter (3.7 Bq/liter) were measured in D-site well water. New groundwater monitoring wells were added in 1989 as a requirement for the groundwater part of our New Jersey Pollutant Discharge Elimination System (NJPDES) permit. Initial sampling of these wells indicated the presence of lead in two shallow wells next to the detention basin. Radiation exposure via airborne effluents into the environment is still at insignificant levels; however, a stack monitor for tritium is planned for 1990 to ensure compliance with new EPA regulations. Off-site surface water, soils, and biota continued to be analyzed for radioactive baselines in CY89. 51 refs., 27 figs., 40 tabs.

    2015-07-01

    The two oldest Armenian calendars - the Haykian and Protohaykian calendars were connected with observations of celestial bodies. Particularly since 2341 B.C. the heliacal rising of the first star of Orion was used to determine the day of the main holiday - Nawasard. Before that the observations of the same star were used in Protohaykian calendar to determine both the beginning and the end of the year. The year was determined as the duration of visibility of the star Betelgeuse. The year started with the heliacal rising of this star and ended with its heliacal setting. The remaining duration was considered to be out of the year. There are also evidences in Armenian medieval literary sources concerning the observations of heliacal rising and setting of Pleiades. An attempt was made to substantiate that the large symbol carved on the rock platform of the small hill in Metzamor also concerns to the Pleiades and shows the direction of heliacal rising of Pleiades.

  1. Human and climatic impact on the environment as derived from colluvial, fluvial and lacustrine archives-examples from the Bronze Age to the Migration period, Germany

    2003-01-01

    Investigation of colluvial, fluvial and lacustrine sediment archives from 12 sites in Germany for the last ca 5000 years demonstrates that there is no synchronous development of the cultural landscape. This can only be explained, if climate is not the dominating control mechanism. However, to a certain degree there is a climatic influence, like during the slight climatic deteriorations immediately following the Holocene climatic optimum, or the stronger ones during the 1st millennium BC and during the Little Ice Age. As shown by all the different archives, human impact strongly increased and became the dominant factor which often made the climatic influence difficult to detect or even invisible. There are indications that human activities may have been triggered by climatic changes. Although the pattern of habitation was in general dependent on the environment offered by nature, also political and socio-economic factors have been involved, resulting in varying occupation patterns in prehistoric and medieval times.

    Dissertation is devoted to rotavirus infections in children 0-14 years of age hospitalized in the hospital of Zyrardów in 2000-2002. The first part of the work describes epidemiology of rotaviral infection in children, rotaviral vaccines and also presents data of rotaviral infections in the foreign and polish literature. The second part is concerning the data of rotaviral infection in children hospitalized in Zyrardów. Stool samples were examined in Bacteriological Laboratory of Powiatowa Stacja Sanitamo-Epidemiologiczna in Zyrardów for bacteria and for rotavirus by means of agglutination latex test Slidex Rota-Kit 2. All children with acute gastroenteritis rotaviral were hospitalized. The most of children were 0-4 years old. They had 89,1% of participation in the whole group of admitted children. In dissertation there were represented data in tables, concerning number of rotaviral diarrhea episodes in children 0-14 years with division into age groups, sex and urban-rural children, seasonality of infections and nosocomial rotaviral infections. The next part of the work is the anonymous survey containing five questions about social and family conditions of these children, which have fallen ill the rotaviral infection. The survey served to carry out the case-control research intending detection the risk factors for incidence of rotaviral infections in children. Conclusions of the survey: risk factors - sleeping with children in one room, more than three persons and improper sanitary conditions (lack of own bathroom in the apartment). PMID:17682758

    "If you lie awake worrying about the overnight transition from December 31, 1 b.c., to January 1, a.d. 1 (there is no year zero), then you will enjoy Duncan Steel's Marking Time."--American Scientist "No book could serve as a better guide to the cumulative invention that defines the imaginary threshold to the new millennium."--Booklist A Fascinating March through History and the Evolution of the Modern-Day Calendar . . . In this vivid, fast-moving narrative, you'll discover the surprising story of how our modern calendar came about and how it has changed dramatically through the years. Acclaimed author Duncan Steel explores each major step in creating the current calendar along with the many different systems for defining the number of days in a week, the length of a month, and the number of days in a year. From the definition of the lunar month by Meton of Athens in 432 b.c. to the roles played by Julius Caesar, William the Conqueror, and Isaac Newton to present-day proposals to reform our calendar, this entertaining read also presents "timely" tidbits that will take you across the full span of recorded history. Find out how and why comets have been used as clocks, why there is no year zero between 1 b.c. and a.d. 1, and why for centuries Britain and its colonies rang in the New Year on March 25th. Marking Time will leave you with a sense of awe at the haphazard nature of our calendar's development. Once you've read this eye-opening book, you'll never look at the calendar the same way again.

  13. Variation in fecal testosterone levels, inter-male aggression, dominance rank and age during mating and post-mating periods in wild adult male ring-tailed lemurs (Lemur catta).

    PubMed

    2007-12-01

    In primate species exhibiting seasonal reproduction, patterns of testosterone excretion in adult males are variable: in some species, peaks correlate with female receptivity periods and heightened male-male aggression over access to estrous females, in others, neither heightened aggression nor marked elevations in testosterone have been noted. In this study, we examined mean fecal testosterone ( f T) levels and intermale aggression in wild adult male ring-tailed lemurs residing in three groups at Beza Mahafaly Reserve, Madagascar. Results obtained from mating and post-mating season 2003 were compared to test Wingfield et al. [1990. Am Nat 136:829-846] "challenge hypothesis", which predicts a strong positive relationship between male testosterone levels and male-male competition for access to receptive females during breeding season. f T levels and rates of intermale aggression were significantly higher during mating season compared to the post-mating period. Mean f T levels and aggression rates were also higher in the first half of the mating season compared with the second half. Number of males in a group affected rates of intermale agonism, but not mean f T levels. The highest-ranking males in two of the groups exhibited higher mean f T levels than did lower-ranking males, and young males exhibited lower f T levels compared to prime-aged and old males. In the post-mating period, mean male f T levels did not differ between groups, nor were there rank or age effects. Thus, although male testosterone levels rose in relation to mating and heightened male-male aggression, f T levels fell to baseline breeding levels shortly after the early mating period, and to baseline non-breeding levels immediately after mating season had ended, offsetting the high cost of maintaining both high testosterone and high levels of male-male aggression in the early breeding period.

  14. Low reservoir ages for the surface ocean from mid-Holocene Florida corals

    The 14C reservoir age of the surface ocean was determined for two Holocene periods (4908-4955 and 3008-3066 calendar (cal) B.P.) using U/Th-dated corals from Biscayne National Park, Florida, United States. We found that the average reservoir ages for these two time periods (294 ?? 33 and 291 ?? 27 years, respectively) were lower than the average value between A.D. 1600 and 1900 (390 ?? 60 years) from corals. It appears that the surface ocean was closer to isotopic equilibrium with CO2 in the atmosphere during these two time periods than it was during recent times. Seasonal ??18O measurements from the younger coral are similar to modern values, suggesting that mixing with open ocean waters was indeed occurring during this coral's lifetime. Likely explanations for the lower reservoir age include increased stratification of the surface ocean or increased ??14C values of subsurface waters that mix into the surface. Our results imply that a more correct reservoir age correction for radiocarbon measurements of marine samples in this location from the time periods ???3040 and ???4930 cal years B.P. is ???292 ?? 30 years, less than the canonical value of 404 ?? 20 years.

    -fold higher than in controls (p<0.0001), probably reflecting increased cortisol levels throughout the third trimester of pregnancy. No differences in cortisol content were apparent for the second or third 3-cm segments in n-Mothers (p>0.2). When hair from mothers with 6-9 months old toddlers was analyzed, the hair segment representing the third trimester period contained the same amount of cortisol as the hair grown more recently in mothers with 3-4 months old toddlers only. Age of the women, hair curvature, hair color, and frequency of hair washes per week were unrelated to cortisol levels. We conclude that cortisol measured in human hair can be a valid reflection of increased cortisol production for a period of up to six months. Due to a rapid decline of cortisol levels in human adult hair, a retrospective calendar of cortisol exposure may be limited to the past six months. PMID:18947933

    Radiocarbon dating of short-lived sample materials is a useful tool applied to date deposits of volcanic eruptions. Several archaeological sites discovered and excavated in Campania witnessed important volcanic eruptions, which occurred in the Copper and Middle Bronze Ages. These eruptions come from the Somma-Vesuvius complex and the Phlaegrean Fields caldera. At least four Plinian eruptions have been identified in the eruptive history of Somma-Vesuvius, interspersed by interplinian events, called protohistoric, which occurred between Avellino and Pompeii. At S. Paolo Belsito a stratigraphic sequence below Avellino and above the first two protohistoric events after Avellino were highlighted; while Nola (Naples) gives new information on the chronology of Avellino. Sites like Caivano and Gricignano D'Aversa, involved by the Agnano 3, Paleoastroni 2 and Agnano Monte Spina eruptions were highlighted and investigated. In this work, we want to clarify the chronology of some eruptions by comparing our results with previous data. Charcoal, bone and seed samples were collected, treated and measured at the CIRCE laboratory in Caserta.

  17. Changes in dietary practices and social organization during the pivotal late iron age period in Norway (AD 550-1030): isotope analyses of Merovingian and Viking Age human remains.

    2014-11-01

    Human remains representing 33 individuals buried along the coast in northern Norway were analyzed for diet composition using collagen stable carbon and nitrogen isotope analysis. Where possible, both teeth and bone were included to investigate whether there were dietary changes from childhood to adulthood. A general shift was documented from the Merovingian Age 550-800 AD to the Viking Age AD 800-1050 (VA), with a heavier reliance on marine diet in the VA. Dietary life history data show that 15 individuals changed their diets through life with 11 of these having consumed more marine foods in the later years of life. In combination with (87) Sr/(86) Sr data, it is argued that at least six individuals possibly originated from inland areas and then moved to the coastal region where they were eventually interred. The trend is considered in relation to the increasing expansion of the marine fishing industry at this time, and it is suggested that results from isotope analyses reflect the expanding production and export of stockfish in this region.

    Ancient DNA methodology was applied to analyse sequences extracted from freshly unearthed remains (teeth) of 4 individuals deeply deposited in slightly alkaline soil of the Tell Ashara (ancient Terqa) and Tell Masaikh (ancient Kar-Assurnasirpal) Syrian archaeological sites, both in the middle Euphrates valley. Dated to the period between 2.5 Kyrs BC and 0.5 Kyrs AD the studied individuals carried mtDNA haplotypes corresponding to the M4b1, M49 and/or M61 haplogroups, which are believed to have arisen in the area of the Indian subcontinent during the Upper Paleolithic and are absent in people living today in Syria. However, they are present in people inhabiting today's Tibet, Himalayas, India and Pakistan. We anticipate that the analysed remains from Mesopotamia belonged to people with genetic affinity to the Indian subcontinent since the distribution of identified ancient haplotypes indicates solid link with populations from the region of South Asia-Tibet (Trans-Himalaya). They may have been descendants of migrants from much earlier times, spreading the clades of the macrohaplogroup M throughout Eurasia and founding regional Mesopotamian groups like that of Terqa or just merchants moving along trade routes passing near or through the region. None of the successfully identified nuclear alleles turned out to be ΔF508 CFTR, LCT-13910T or Δ32 CCR5. PMID:24040024

    2002-08-01

    This paper presents the test results and life modeling of special calendar- and cycle-life tests conducted on 18650-size generation 1 (Gen 1) lithium-ion battery cells (nominal capacity of 0.9 Ah; 3.0–4.1 V rating) developed to establish a baseline chemistry and performance for the Department of Energy sponsored advanced technology development (ATD) program. Electrical performance testing was conducted at the Argonne National Laboratory (ANL), Sandia National Laboratory (SNL) and the Idaho National Engineering and Environmental Laboratory (INEEL). As part of the electrical performance testing, a new calendar-life test protocol was used. The test consisted of a once per day discharge and charge pulse designed to have minimal impact on the cell yet establish its performance over a period of time such that the calendar-life of the cell could be determined. The calendar-life test matrix included two states-of-charge (SOCs) (i.e. 60 and 80%) and four test temperatures (40, 50, 60 and 70 °C). Discharge and regen resistances were calculated from the test data. Results indicate that both the discharge and regen resistances increased non-linearly as a function of the test time. The magnitude of the resistances depended on the temperature and SOC at which the test was conducted. Both resistances had a non-linear increase with respect to time at test temperature. The discharge resistances are greater than the regen resistances at all of the test temperatures of 40, 50, 60 and 70 °C. For both the discharge and regen resistances, generally the higher the test temperature, the lower the resistance.

    Objective—To determine whether implantable cardioverter-defibrillator (ICD) treatment is beneficial in elderly patients with life threatening ventricular tachyarrhythmias.
Design—Since January 1984, ICDs were implanted in 450 patients to evaluate surgical risk, complications and mean survival in relation to patient age; 81 patients (18%) were ⩽ 50 years at the time of ICD implant, 254 patients (56%) were between 51 and 64 years, and the remaining 115 (26%) were ⩾ 65 years. Epicardial lead systems were implanted in 209 patients (46%), while transvenous lead systems were implanted in 241 (54%).
Results—13 patients (3%) died perioperatively, more often after epicardial (11 of 209 patients, 5%) than after transvenous ICD implantation (one of 241 patients, < 1%) (p < 0.05). During a mean (SD) follow up of 28 (24) months (range < 1 to 114 months), 90 patients (20%) died. Of these, nine (2%) died from sudden arrhythmic death; five (1%) died suddenly, probably as a result of non-arrhythmic causes; 55 (12%) died from other cardiac causes (congestive heart failure, myocardial infarction); and 21 (5%) died from non-cardiac causes. The three, five, and seven year survival for arrhythmic mortality was 95% in patients ⩽ 50 years compared with a three year survival of 93% and a five and seven year survival of 91% in patients of 51 to 64 years, and a three, five, and seven year survival of 99% in patients ⩾ 65 years. 362 patients (80%) received ICD discharges (21 (43) shocks per patient), with a similar incidence among all three patient groups (⩽ 50 years, 80%; 51 to 64 years, 81%; ⩾ 65 years, 79%). The time interval between ICD implant and the first ICD treatment was shorter in patients ⩾ 65 years (8 (8) months) than in patients between 51 and 64 years (11 (14) months) or ⩽ 50 years (11 (11) months) (p < 0.05). Survival time following first appropriate shock was 30 (24) months in patients ⩽ 50 years, 30 (26

    We are revising the rules to automatically adjust each year, based on any increases in the national average wage index, the average monthly earnings guideline we use to determine whether work done by persons with impairments other than blindness is substantial gainful activity; provide that we will ordinarily find that an employee whose average monthly earnings are not greater than the "primary substantial gainful activity amount," has not engaged in substantial gainful activity without considering other information beyond the employee's earnings; increase the minimum amount of monthly earnings and the minimum number of self-employed work hours in month that we consider shows that a person receiving title II Social Security benefits based on disability is performing or has performed "services" during a trial work period, and automatically adjust the earnings amount each year thereafter; increase the maximum monthly and yearly Student Earned Income Exclusion amounts we use in determining Supplemental Security Income (SSI) Program eligibility and payment amounts for student children, and automatically adjust the monthly and yearly exclusion amounts each year thereafter. We are revising these rules as part of our efforts to encourage individuals with disabilities to test their ability to work and keep working. We expect that these changes will provide greater incentives for many beneficiaries to attempt to work or, if already working, to continue to work or increase their work effort. PMID:11503739

    New radiocarbon calibration curves, IntCal04 and Marine04, have been constructed and internationally ratified to replace the terrestrial and marine components of IntCal98. The new calibration datasets extend an additional 2000 years, from 0-26 ka cal BP (Before Present, 0 cal BP = AD 1950), and provide much higher resolution, greater precision and more detailed structure than IntCal98. For the Marine04 curve, dendrochronologically dated tree-ring samples, converted with a box-diffusion model to marine mixed-layer ages, cover the period from 0-10.5 ka cal BP. Beyond 10.5 ka cal BP, high-resolution marine data become available from foraminifera in varved sediments and U/Th-dated corals. The marine records are corrected with site-specific {sup 14}C reservoir age information to provide a single global marine mixed-layer calibration from 10.5-26.0 ka cal BP. A substantial enhancement relative to IntCal98 is the introduction of a random walk model, which takes into account the uncertainty in both the calendar age and the radiocarbon age to calculate the underlying calibration curve. The marine datasets and calibration curve for marine samples from the surface mixed layer (Marine04) are discussed here. The tree-ring datasets, sources of uncertainty, and regional offsets are presented in detail in a companion paper by Reimer et al.

  5. The Accuracy of the Five-planet Locations Calculated by the Chinese Ancient Calendar Named Shoushi Li

    NASA Astrophysics Data System (ADS)

    Li, Y.

    2011-01-01

    The calendar Shoushi Li is one of the most famous calendars in ancient China, which was recorded in the Lizhi (ancient calendar book of China) of Yuanshi (annals of the Yuan Dynasty from 1279 to 1367). There are seven important calculation parts, including solar terms, syzygies, corrections of the sun and the moon, eclipses and so on. The locations of the five-planet are also in the list. Almost every part has a corresponding section in the modern astronomical year book. It is the last calendar formulated only by Chinese astronomers and its period of usage (from 1281 to 1644) is the longest one in ancient China. It was also a new calendar system which cast off the traditional method by which calculations were carried out from the epoch of the distant past. The basic constants were obtained by meticulous observations and then used in calculations. In this paper, the calculation methods of planetary locations in Shoushi Li are investigated and recovered by studying the official texts of Yuanshi. (1) The locations of the ephemeris of Jupiter in 1299 are derived and our recovering method is affirmed by comparing with other studies. (2) The calculated accuracies of celestial longitudes of the five-planet from 1280 to 1650 are obtained. For Jupiter, Mars, Saturn, Venus and Mercury, the average values of absolute errors are 0.49°, 1.91°, 0.70°, 2.82° and 5.01°. Jupiter and Saturn have comparatively higher accuracies. (3) Zhoulu, Lilu, Dulu, Heying and Liying are used for planetary calculations in Shoushi Li. Their accurate values, instead of those adopted in Shoushi Li, are derived and calculated by modern astronomical methods and then inputted into Shoushi models. It is found that the accuracies of planetary locations are not improved. The errors of Jupiter and Saturn are 1.83°and 1.21°. But the errors of Mercury, Venus and Mars ascend to 30.04°, 54.86°and 10.82°, respectively. It is indicated that the accuracies can not be increased by revising some of the

    years ago) age offsets nearly doubled to around 4,000 calendar years. Because most of the deepest and oldest organic-rich soils in the LOP watershed are located in topographical lowlands in the northern Brooks Range region today, we hypothesize that these regions are where ancient organic matter was released during the HTM. The thick peat that now covers these lowlands is insulating the permafrost and likely stabilizing permafrost C in the face of recent warming causing lake sediment age offsets to be similar to those offsets during a period of relatively cold, and unproductive soils. The vulnerability of permafrost C is evidenced by the limit of peat stabilization that was apparently crossed during the ~ 2-3° C of rapid warming that occurred at the end of the Younger Dryas.

    Dicrocoeliasis of animals and humans is caused by trematode species of the genus Dicrocoelium, mainly Dicrocoelium dendriticum in ruminants of the Holarctic region. D. dendriticum may be considered an old parasite, probably related to the appearance and diversification of Eurasian ovicaprines, occurred 14.7-14.5 million years ago. The oldest palaeoparasitological findings of Dicrocoelium in domestic animals and humans date from more than 5000 years BC in Europe. Eggs of D. dendriticum have been found in a burial of a Bronze Age cemetery (2600-2200 BC) close to Yasuj city, southwestern Iran. This is the oldest finding of D. dendriticum in the Near East, where present human infection reports are more numerous than in other world regions where human dicrocoeliasis is rare and sporadic. This palaeofinding in the Zagros mountainous chain area is of interest by its location close to Persepolis, suggesting a narrow relationship between humans and herbivorous animals in these highlands. Domestic ruminant populations of these highlands were following a repeated contact with those of the western flat lowlands of the Fertile Crescent thanks to annual altitudinal transhumance migrations of the nomadic pastoral tribes with their herds living throughout Zagros Mountains in the several millennium period BC. It is concluded that D. dendriticum spread together with sheep and goats westward throughout Europe from the Fertile Crescent during the 8000-6000 year BC period and somewhat later southward into Africa, both spreads facilitated by the low specificity of that trematode species regarding the snail and ant intermediate hosts.

    1975-06-01

    The data of research which has been carried out for years, are summarized. They are presented in a succession conforming to the A.A. Ukhtomsky views on the gradual enlargement of amplitude of muscles contraction, on capacity for work, and on fatigue. In the early postnatal period the phenomenon of gradual enlargement of amplitude of muscles contraction does not yet exist. It only appears after realizaiton of standing posture, when skeletal muscles transit from the type of tonic activity to the phasic--tetanic type. This phenomenon is due to that the first contractions induce hyperrelaxation which leads to the subsequent higher amplitude of contraction. The steady state of work capacity of neuromuscular system without any changes of amplitude, in the conditions of undisturbed circulation in the organism as a whole, can be maintained in all the periods of age for a long time without any signs of fatigue. This phenomenon takes place during the intervals between the contraction activity, the anabolic process having ample time to be completed. Such a form of work capacity is called stability. If the anabolic processes are unable to be completed during the intervals between the contractions, their amplitude gradually decreases reflecting the beginning of fatigue. The contractile activity which is going on during the fatigue state, is called endurance. PMID:1093901

  15. Periodic Polymers

    NASA Astrophysics Data System (ADS)

    Thomas, Edwin

    2013-03-01

    Periodic polymers can be made by self assembly, directed self assembly and by photolithography. Such materials provide a versatile platform for 1, 2 and 3D periodic nano-micro scale composites with either dielectric or impedance contrast or both, and these can serve for example, as photonic and or phononic crystals for electromagnetic and elastic waves as well as mechanical frames/trusses. Compared to electromagnetic waves, elastic waves are both less complex (longitudinal modes in fluids) and more complex (longitudinal, transverse in-plane and transverse out-of-plane modes in solids). Engineering of the dispersion relation between wave frequency w and wave vector, k enables the opening of band gaps in the density of modes and detailed shaping of w(k). Band gaps can be opened by Bragg scattering, anti-crossing of bands and discrete shape resonances. Current interest is in our group focuses using design - modeling, fabrication and measurement of polymer-based periodic materials for applications as tunable optics and control of phonon flow. Several examples will be described including the design of structures for multispectral band gaps for elastic waves to alter the phonon density of states, the creation of block polymer and bicontinuous metal-carbon nanoframes for structures that are robust against ballistic projectiles and quasi-crystalline solid/fluid structures that can steer shock waves.

    OBJECTIVE To clarify whether the increase in childhood type 1 diabetes is mirrored by a decrease in older age-groups, resulting in younger age at diagnosis. RESEARCH DESIGN AND METHODS We used data from two prospective research registers, the Swedish Childhood Diabetes Register, which included case subjects aged 0–14.9 years at diagnosis, and the Diabetes in Sweden Study, which included case subjects aged 15–34.9 years at diagnosis, covering birth cohorts between 1948 and 2007. The total database included 20,249 individuals with diabetes diagnosed between 1983 and 2007. Incidence rates over time were analyzed using Poisson regression models. RESULTS The overall yearly incidence rose to a peak of 42.3 per 100,000 person-years in male subjects aged 10–14 years and to a peak of 37.1 per 100,000 person-years in female subjects aged 5–9 years and decreased thereafter. There was a significant increase by calendar year in both sexes in the three age-groups <15 years; however, there were significant decreases in the older age-groups (25- to 29-years and 30- to 34-years age-groups). Poisson regression analyses showed that a cohort effect seemed to dominate over a time-period effect. CONCLUSIONS Twenty-five years of prospective nationwide incidence registration demonstrates a clear shift to younger age at onset rather than a uniform increase in incidence rates across all age-groups. The dominance of cohort effects over period effects suggests that exposures affecting young children may be responsible for the increasing incidence in the younger age-groups. PMID:21680725

But to know the capacity of battery units is necessary, e.g. to select most equal cells for battery pack assembly or to decide whether single units of an aged battery pack are worthy to be reused in a 2nd-life application. So, a quick and easy approach to refer to the actual capacity is of great technical and economic interest. In this paper, the correlation between capacity and impedance of lithium-ion cells during calendar and cycle life is analyzed and assessed, whether it can serve as a base for capacity quick tests. Therefore, new cells, cells aged in the laboratory and those out of two identical electric vehicles are characterized to yield a broad set of data. Results of this work imply the feasibility of correlation based capacity quick tests. However, parameterization of needed functional dependencies between capacity and impedance must be done with laboratory aging data similar to the practical use as a strong dependency of the correlation behavior from the operational and storage conditions is observed. Especially high temperature leads to strong deviation which could be linked to the layered structure of the solid electrolyte interphase.

    Special ability in computing the day of the week from given dates was observed in a 18 years old male, L.E., suffering from autism. Neuropsychological testing revealed severe deficits in all cognitive domains and poor explicit knowledge of calendar structure. The subject scored well above the chance level on dates of the past and future decades. Error rate and response latency increased with temporal remoteness of dates. Most of errors were in indicating the weekday before or after that of date stimulus. The performance and error pattern suggest that L.E. used "encapsulated" computation algorithm(s) for the day of week task. PMID:16900402

    , when abrupt wet seasons follow drier ones every 30 to 40 years. We propose this cycle would match with the Pacific Decadal Oscillation, a pattern of change (warm or cool surface waters) in the Pacific Ocean's climate that occurs every 20 to 30 years. Furthermore, a major climatic shift around the 1600s is also apparent, when both δ18O and δ13C in the Dante Cave stalagmite decrease by ~ 3-4 ‰, indicating a dramatic change from dry to wet conditions. This change is followed by a shift to a drier climate from 1650 to 1950 for both DP1 and BC97-94. The abrupt change in isotopic data is coeval with the transition from the Medieval Climate Anomaly (prior to AD 1600) to the Little Ice Age (~AD 1350-1850), and possibly the onset of the Maunder Sunspot Minimum (1645-1715). The stalagmite data show that major Late Holocene climate events recorded in the Northern Hemisphere also impacted the Southern Hemisphere, including Southern Africa. The rapid changes in isotopic values are also mirrored by changes in stalagmite petrography. Crystals of calcite with a distinctly brownish/yellowish color in DP1 samples reflect the wet period in Namibia, and a Type E (erosional) layer-bounding surface in BC97-14 marks the onset of the very wet period in Botswana.

  1. Accelerated calendar and pulse life analysis of lithium-ion cells

    NASA Astrophysics Data System (ADS)

    Jungst, Rudolph G.; Nagasubramanian, Ganesan; Case, Herbert L.; Liaw, Bor Yann; Urbina, Angel; Paez, Thomas L.; Doughty, Daniel H.

    Sandia National Laboratories has been studying calendar and pulse discharge life of prototype high-power lithium-ion cells as part of the Advanced Technology Development (ATD) Program. One of the goals of ATD is to establish validated accelerated life test protocols for lithium-ion cells in the hybrid electric vehicle application. In order to accomplish this, aging experiments have been conducted on 18650-size cells containing a chemistry representative of these high-power designs. Loss of power and capacity are accompanied by increasing interfacial impedance at the cathode. These relationships are consistent within a given state-of-charge (SOC) over the range of storage temperatures and times. Inductive models have been used to construct detailed descriptions of the relationships between power fade and aging time and to relate power fade, capacity loss and impedance rise. These models can interpolate among the different experimental conditions and can also describe the error surface when fitting life prediction models to the data.

  2. How to find the sunrise and sunset times from a Sun clock and calendar

    The purpose of this article is to describe the construction of a Sun clock and calendar (SCandC) that will allow an observer to not only see the time but also the symmetry properties of the Sun-Earth relative movement. A set of circles drawn on the SCandC will allow the observer to see their associated dates as well as to perform a visual interpolation between any pair of consecutive circles to estimate an intermediate date. By introducing the sunrise and sunset horizon lines in the SCandC the observer will be able to find the sunrise and sunset times during most of the year. The observer will also be able to appreciate the difference in time duration between the spring-summer and autumn-winter periods, as a consequence of Kepler's second law, as well as to observe that there is a small difference between the circle radii of equidistant dates from the solstices in the spring-summer versus autumn-winter periods as a consequence also of Kepler's second law. The equations derived in the present article will be tested against data from a particular lighthouse.

Operations at the Knolls Site, Niskayuna, New York and the Kesselring Site, West Milton, New York and site closure activities at the S1C Site, Windsor, Connecticut, continued to have no adverse effect on human health and the quality of the environment during calendar year 2000. The effluent and environmental monitoring programs conducted by KAPL are designed to determine the effectiveness of treatment and control methods, to provide measurement of the concentrations in effluents for comparison with applicable standards, and to assess resultant concentrations in the environment. The monitoring programs include analyses of samples of liquid and gaseous effluents for chemical constituents and radioactivity as well as monitoring of environmental air, water, sediment, and fish. Radiation measurements are also made around the perimeter of each Site and at off-site background locations. Monitoring programs at the S1C Site were reduced in scope during calendar year 2000 due to completion of site dismantlement activities during 1999.

  4. Calendar effects in quantum mechanics in view of interactive holography

    NASA Astrophysics Data System (ADS)

    Berkovich, Simon

    2013-04-01

    Quantum mechanics in terms of interactive holography appears as `normal' science [1]. With the holography quantum behavior is determined by the interplay of material formations and their conjugate images. To begin with, this effortlessly elucidates the nonlocality in quantum entanglements. Then, it has been shown that Schr"odinger's dynamics for a single particle arises from Bi-Fragmental random walks of the particle itself and its holographic image. For many particles this picture blurs with fragments merging as bosons or fermions. In biomolecules, swapping of particles and their holographic placeholders leads to self-replication of the living matter. Because of broad interpretations of quantum formalism direct experiments attributing it to holography may not be very compelling. The holographic mechanism better reveals as an absolute frame of reference. A number of physical and biological events exhibit annual variations when Earth orbital position changes with respect to the universal holographic mechanism. The well established calendar variations of heart attacks can be regarded as a positive outcome of a generalization of the Michelson experiment, where holography is interferometry and ailing hearts are detectors of pathologically replicated proteins. Also, there have been already observed calendar changes in radioactive decay rates. The same could be expected for various fine quantum experiences, like, e.g., Josephson tunneling. In other words, Quantum Mechanics (February) Quantum Mechanics (August). [1] S. Berkovich, ``A comprehensive explanation of quantum mechanics,'' www.cs.gwu.edu/research/technical-report/170 .

  8. Deriving crop calendar using NDVI time-series

    NASA Astrophysics Data System (ADS)

    Patel, J. H.; Oza, M. P.

    2014-11-01

    Agricultural intensification is defined in terms as cropping intensity, which is the numbers of crops (single, double and triple) per year in a unit cropland area. Information about crop calendar (i.e. number of crops in a parcel of land and their planting & harvesting dates and date of peak vegetative stage) is essential for proper management of agriculture. Remote sensing sensors provide a regular, consistent and reliable measurement of vegetation response at various growth stages of crop. Therefore it is ideally suited for monitoring purpose. The spectral response of vegetation, as measured by the Normalized Difference Vegetation Index (NDVI) and its profiles, can provide a new dimension for describing vegetation growth cycle. The analysis based on values of NDVI at regular time interval provides useful information about various crop growth stages and performance of crop in a season. However, the NDVI data series has considerable amount of local fluctuation in time domain and needs to be smoothed so that dominant seasonal behavior is enhanced. Based on temporal analysis of smoothed NDVI series, it is possible to extract number of crop cycles per year and their crop calendar. In the present study, a methodology is developed to extract key elements of crop growth cycle (i.e. number of crops per year and their planting - peak - harvesting dates). This is illustrated by analysing MODIS-NDVI data series of one agricultural year (from June 2012 to May 2013) over Gujarat. Such an analysis is very useful for analysing dynamics of kharif and rabi crops.

  9. Age Rules

    NASA Astrophysics Data System (ADS)

    Taylor, G. J.

    2015-10-01

    The ages of rocks from the lunar highlands vary widely, even for a single rock sample. This makes it difficult to quantitatively test ideas for early lunar differentiation and formation of the crust. Lars Borg and Amy Gaffney (Lawrence Livermore National Laboratory), and Charles Shearer (University of New Mexico) have devised a set of guidelines to apply to geochronological data that leads to a relative ranking of the reliability of the age determined for a sample. Applying their guidelines to existing data for lunar highland rocks shows an upper limit on rock ages between 4340 and 4370 million years. This is essentially the same as the so-called model ages of the formation of KREEP (a chemical component enriched in potassium, rare earth elements, and phosphorous) and of the formation of the deep source regions that melted to produce mare basalts. The numerous ages close to 4370 million years suggests a complicated and protracted cooling of the primordial lunar magma ocean or a widespread vigorous period of magmatic activity in the Moon.

  10. Calendar effect on phase study in paleoclimate transient simulation with orbital forcing

    NASA Astrophysics Data System (ADS)

    Chen, Guang-Shan; Kutzbach, J. E.; Gallimore, R.; Liu, Zhengyu

    2011-11-01

    Several studies have shown that the use of different calendars in paleoclimate simulations can cause artificial phase shifts on insolation forcing and climatic responses. However, these important calendar corrections are still often neglected. In this paper, the phase shifts at the precession band is quantitatively assessed by converting the model data of the transient GCM climate simulation of Kutzbach et al. (Clim Dyn 30:567-579, 2008) from the "fixed-day" calendar to the "fixed-angular" calendar with a new and efficient approach. We find that insolation has a big phase shift in September-October-November (SON) when the vernal equinox (VE) is fixed to March 21. At high latitude, the phase bias is up to 60° (about 3650 years). The insolation phase bias in SON in Southern Hemisphere (SH) is especially important because it can influence the timing of the SH summer monsoon response due to the large heat capacity of ocean. The calendar correction has minor effect (±2°) on the phase relationships between forcing and precipitation responses of the six global summer monsoons studied in Kutzbach et al. (2008). After correcting the calendar effect, especial on SH ocean temperature, the new phase wheel results are more similar for both hemispheres. The results suggest that the calendar effect should be corrected before discussing the dynamics between orbital forcing and climatic responses in phase studies of transient simulations.

    Two calendrical sye parallely used in Macedonia during the Roman occupation. Both systems had kept the ancient greek names of the months as they were given in the ancient greek Macedonian Calendar. Also, both systems started with the same month Dios but they differed in the starting year. The older one started with the "Macedonian year" in 148 B.C., the year of the victory of the Roman Consul Q.C.Metellus against the revolution of Pseudo-Phillipus Andriscus. The second one started in 31 B.C., which was known as the "respectful" year. This year indicates the victory of Octavian Augustus over Marcus Antonius and Cleopatra in Aktion on September 2 of the year 31 B.C.

    The results of the effluent and environmental monitoring programs at the three Knolls Atomic Power Laboratory (KAPL) Sites are summarized and assessed in this report. Operations at the three KAPL Sites [Knolls Site, Niskayuna, New York; Kesselring Site, West Milton, New York; S1C Site, Windsor, Connecticut] during calendar year 1999 resulted in no significant release of hazardous substances or radioactivity to the environment. The effluent and environmental monitoring programs conducted by KAPL are designed to determine the effectiveness of treatment and control methods, to provide measurement of the concentrations in effluents for comparison with applicable standards, and to assess resultant concentrations in the environment. The monitoring programs include analyses of samples of liquid and gaseous effluents for chemical constituents and radioactivity as well as monitoring of environmental air, water, sediment, and fish. Radiation measurements are also made around the perimeter of each Site and at off-site background locations.

    We present a model-data comparison between the CMIP5/PMIP3 last millennium simulations and available individual temperature proxy records from across the globe. Our focus is to investigate the agreement in amplitude of the simulated and the reconstructed temperature difference between the Medieval Warm Period (MWP, here defined as AD 950-1250) and the Little Ice Age (LIA, here defined as AD 1400-1700). An emphasis is placed on analysing to what extent the high latitude and continental amplification of the temperature signal is the same in the model simulations as in the proxies. We further discuss to what extent the models have captured the spatial signatures that is shown in the proxy data. We have collected 125 calibrated proxy records - representing either annual mean, winter or summer temperature - extending back to at least AD 950. The proxies include data from a wide range of archives: ice-cores, marine and terrestrial sediments, tree-rings, speleothems and historical records. Only proxies with at least two observations per century were included. We calculated the amplitude of change between the MWP and the LIA in the individual proxy records using the temperature calibrations by the original authors. The last millennium simulations from 8 different models in CMIP5 database are used to compare with the proxy records. This model-data comparison reveals that the ensemble mean and median of the models mostly underestimate the amplitude of temperature difference between the MWP and the LIA as estimated from the proxy records at those locations where proxy records exist. The relative lack of proxy data from the tropics and the Southern Hemisphere, however, precludes a fully comprehensive model-data comparison. We also note large differences between the model simulations both in amplitude of the temperature change and in their spatial patterns. The use of an ensemble mean or median of the model simulations emphasizes the averaged signature within the model ensemble

  1. Measuring the lifetime experience of domestic violence: application of the life history calendar method.

    In the absence of a "gold standard," research on domestic violence relies primarily on self-report, the quality of which is known to decline as the length of the recall period increases. Eliciting valid and reliable self-report data is crucial to the development of prevention and intervention policies and services. Nevertheless, existing measures typically do not incorporate devices to facilitate respondents' recall of the lifetime experience of domestic violence. This article describes the application of the Life History Calendar (LHC) method (Freedman, Thornton, Camburn, Alwin, & Young-DeMarco, 1988) to increase a respondent's recall of domestic violence victimization over the lifecourse. The LHC method elicits memorable information of a personal nature (e.g., children's birth dates) and uses this information to facilitate the recall of less memorable events. A recent field test of this LHC measure indicates its utility in assessing domestic violence victimization, which takes place in a complex sequence of episodes and often involves multiple perpetrators over the lifecourse.

    Extremely high fine particulate matter (PM2.5) concentration has become synonymous to Beijing, the capital of China, posing critical challenges to its sustainable development and leading to major public health concerns. In order to formulate mitigation measures and policies, knowledge on PM2.5 variation patterns should be obtained. While previous studies are limited either because of availability of data, or because of problematic a priori assumptions that PM2.5 concentration follows subjective seasonal, monthly, or weekly patterns, our study aims to reveal the data on a daily basis through visualization rather than imposing subjective periodic patterns upon the data. To achieve this, we conduct two time-series cluster analyses on full-year PM2.5 data in Beijing in 2014, and provide an innovative calendar visualization of PM2.5 measurements throughout the year. Insights from the analysis on temporal variation of PM2.5 concentration show that there are three diurnal patterns and no weekly patterns; seasonal patterns exist but they do not follow a strict temporal division. These findings advance current understanding on temporal patterns in PM2.5 data and offer a different perspective which can help with policy formulation on PM2.5 mitigation. PMID:27561629

  12. The Characters of Leap Years in Qing Calendars (1644-1911)

    NASA Astrophysics Data System (ADS)

    Lu, Dalong

    In Qing Dynasty (1644-1911) three different calendars had been put into use which titles are Xiyang Xinfa Lishu (Treatise on Astronomy and Calendrical Science according to the New Method in West 1645-1666) Yuzhi Lixiang Kaocheng (Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1725-1742) and Yuzhi Lixiang Kaocheng Houbian (Sequel Compendium of Calendrical Science and Astronomy compiled by Imperial Order 1742-1911). The characters of leap years in the three calendars are different for the last one which is selected the year of 1723 as it epoch and named as Guimao Yuan Li. This calendar is based on the 33-year pattern of leap years (there is a rather exact accord between days and years over this interval with eight days being intercalated per 33 years) and is slightly different from the former two calendars. Therefore the calendars of Qing Dynasty complied by Western Jesuits and Chinese astronomers can be regarded as the remarkable achievements in the history of calendar in the world.

    Kokott, Wolfgang

    The refusal of most protestant communities in Germany and other countries to accept the calendar reform decreed by Pope Gregor XIII in 1582 was finally circumvented by the introduction of an ``Improved (Julian) Calendar''. It did provide for astronomical rather than cyclical calculation of the date of Easter. While for most years both calendars were identical except in name, some conflicts did eventually occur. This led finally, in 1775, to a decision in favour of the Gregorian mode of calculation.

  19. Pedogenic calcite as evidence for an early Holocene dry period in the San Francisco Bay area, California

    USGS Publications Warehouse

    Borchardt, G.; Lienkaemper, J.J.

    1999-01-01

    Rainfall at the site of Union City, California, during early Holocene time appears to have been about half that of today, 470 mm/yr. We base this conclusion on detailed descriptions and particle-size analyses of 12 soil profiles and 1:20 scale logs of the fluvial stratigraphy in two 100-m-long, 5-m-deep excavations dug perpendicular to the axis of an alluvial fan along the Hayward fault. Subsidence and right-lateral movement along the fault allowed an offset stream to produce a nearly continuous alluvial record documented by 35 14C ages on detrital charcoal. Bk (calcitic) horizons in paleosols developed in the fan suggest that a relatively dry climatic period occurred from 10 to 7 ka (calendar-corrected ages). The pedogenic calcite exists primarily as vertically oriented filaments and fine, cavernous nodules formed at ped intersections. Soils and paleosols formed before 10 ka or since 7 ka did not have Bk horizons. Bk horizons that were buried suddenly at 7 ka were overlain by leached zones averaging 41 ?? 3 cm thick - about half the current depth of leaching.

  20. Shifting Milestones of Natural Sciences: The Ancient Egyptian Discovery of Algol's Period Confirmed

    NASA Astrophysics Data System (ADS)

    Jetsu, Lauri; Porceddu, Sebastien

    2015-12-01

    The Ancient Egyptians wrote Calendars of Lucky and Unlucky Days that assigned astronomically influenced prognoses for each day of the year. The best preserved of these calendars is the Cairo Calendar (hereafter CC) dated to 1244-1163 B.C. We have presented evidence that the 2.85 days period in the lucky prognoses of CC is equal to that of the eclipsing binary Algol during this historical era. We wanted to find out the vocabulary that represents Algol in the mythological texts of CC. Here we show that Algol was represented as Horus and thus signified both divinity and kingship. The texts describing the actions of Horus are consistent with the course of events witnessed by any naked eye observer of Algol. These descriptions support our claim that CC is the oldest preserved historical document of the discovery of a variable star. The period of the Moon, 29.6 days, has also been discovered in CC. We show that the actions of Seth were connected to this period, which also strongly regulated the times described as lucky for Heaven and for Earth. Now, for the first time, periodicity is discovered in the descriptions of the days in CC. Unlike many previous attempts to uncover the reasoning behind the myths of individual days, we discover the actual rules in the appearance and behaviour of deities during the whole year.

Independently of the proposal he considers that the task of calendar regulating belongs to a state and for this reason a world conference gathering all states and churches aimed at calendar reform could be organized.

  4. SACRA - a method for the estimation of global high-resolution crop calendars from a satellite-sensed NDVI

    NASA Astrophysics Data System (ADS)

    Kotsuki, S.; Tanaka, K.

    2015-11-01

    To date, many studies have performed numerical estimations of biomass production and agricultural water demand to understand the present and future supply-demand relationship. A crop calendar (CC), which defines the date or month when farmers sow and harvest crops, is an essential input for the numerical estimations. This study aims to present a new global data set, the SAtellite-derived CRop calendar for Agricultural simulations (SACRA), and to discuss advantages and disadvantages compared to existing census-based and model-derived products. We estimate global CC at a spatial resolution of 5 arcmin using satellite-sensed normalized difference vegetation index (NDVI) data, which corresponds to vegetation vitality and senescence on the land surface. Using the time series of the NDVI averaged from three consecutive years (2004-2006), sowing/harvesting dates are estimated for six crops (temperate-wheat, snow-wheat, maize, rice, soybean and cotton). We assume time series of the NDVI represent the phenology of one dominant crop and estimate CCs of the dominant crop in each grid. The dominant crops are determined using harvested areas based on census-based data. The cultivation period of SACRA is identified from the time series of the NDVI; therefore, SACRA considers current effects of human decisions and natural disasters. The difference between the estimated sowing dates and other existing products is less than 2 months (< 62 days) in most of the areas. A major disadvantage of our method is that the mixture of several crops in a grid is not considered in SACRA. The assumption of one dominant crop in each grid is a major source of discrepancy in crop calendars between SACRA and other products. The disadvantages of our approach may be reduced with future improvements based on finer satellite sensors and crop-type classification studies to consider several dominant crops in each grid. The comparison of the CC also demonstrates that identification of wheat type (sowing in

    This report discusses the status and the accomplishments of the environmental protection program at Argonne National Laboratory for calendar year 2009. The status of Argonne environmental protection activities with respect to compliance with the various laws and regulations is discussed, along with the progress of environmental corrective actions and restoration projects. To evaluate the effects of Argonne operations on the environment, samples of environmental media collected on the site, at the site boundary, and off the Argonne site were analyzed and compared with applicable guidelines and standards. A variety of radionuclides were measured in air, surface water, on-site groundwater, and bottom sediment samples. In addition, chemical constituents in surface water, groundwater, and Argonne effluent water were analyzed. External penetrating radiation doses were measured, and the potential for radiation exposure to off-site population groups was estimated. Results are interpreted in terms of the origin of the radioactive and chemical substances (i.e., natural, Argonne, and other) and are compared with applicable environmental quality standards. A U.S. Department of Energy (DOE) dose calculation methodology, based on International Commission on Radiological Protection recommendations and the U.S. Environmental Protection Agency's (EPA) CAP-88 Version 3 (Clean Air Act Assessment Package-1988) computer code, was used in preparing this report.

    Background Overall, there is a dearth of research reporting mixed-method data collection procedures using the LHC within disability research. Objective This report provides practical knowledge on use of the life history calendar (LHC) from the perspective of a mixed-method life history study of mobility impairment situated within a qualitative paradigm. Methods In this paper the method related literature referring to the LHC was reviewed along with its epistemological underpinnings. Further, the uses of the LHC in disability research were illustrated using preliminary data from reports of disablement in Mexican American and Non-Hispanic White women with permanent mobility impairment. Results From our perspective, the LHC was most useful when approached from an interpretive paradigm when gathering data from women of varied ethnic and socioeconomic strata. While we found the LHC the most useful tool currently available for studying disablement over the life course, there were challenges associated with its use. The LHC required extensive interviewer training. In addition, large segments of time were needed for completion depending on the type of participant responses. Conclusions Researchers planning to conduct a disability study may find our experience using the LHC valuable for anticipating issues that may arise when the LHC is used in mixed-method research.

    Background and aims. Head and neck tumors are the most common complaints of people referring to different medical sections, especially in children. The aim of this study was to evaluate the prevalence of these tumors in children less than 12 years of age to provide a better perspective for future studies. Materials and methods. All the files in Department of Pathology at Tabriz Pediatric Hospital from 2001 to 2011 were screened for head and neck tumors in children under 12 years of age. Data including age and gender as well as the type, the location, and benign/malignant characteristic of the tumor were recorded. Data were analyzed by SPSS 15 statistical software, using descriptive statistics and chi-square test. Results. A total of 160 cases were identified. Most of the tumors were benign (68%) and most of the tumors occurred in the neck region (41%). The most frequent benign and malignant tumors were lymphangioma and non-Hodgkin lymphoma, respectively. The majority of benign tumors were found in children younger than 2 years old (P=0.007), but there was no age predilection for malignant tumors. Conclusion. According to our results, benign tumors were more prevalent than malignant ones. Although a low rate of benign tumors in males shows that more attention should be paid to the early diagnosis of head and neck tumors. PMID:26236435

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors. PMID:26365061

    Background Dating violence (DV) among youth is an important public health problem. This study examined reasons for physical DV and the association between substance use and youth DV using daily calendar-based analyses among at-risk urban youth. Methods Patients (ages 14–24) presenting to an urban Emergency Department (ED) for a violent injury and a proportionally-selected comparison sample of non-violently injured youth who screened positive for substance use in the past 6 months (n=599) were enrolled in this study. Multi-level, multinomial regressions were conducted using daily-level substance use data from Time Line Follow Back (TLFB) responses and physical DV data that were obtained by coding Time Line Follow Back –Aggression Module responses for the 30 days prior to visiting the ED. Results The two most commonly reported reasons for physical dating aggression and victimization, across sexes, were “jealousy/rumors” or “angry/bad mood.” Multi-level multinomial regression models, adjusting for clustering within individual participants, showed that among females, cocaine use and sedative/opiate use were associated with severe dating victimization and alcohol use was associated with severe dating aggression. Conclusions Use of TLFB data offers a unique opportunity to understand daily-level factors associated with specific incidents of DV in more detail. This study provides novel data regarding reasons for DV and the relationship between daily substance use and DV among urban youth, with alcohol, cocaine, and sedative/opiate use being associated with various types of DV. ED based DV interventions should be tailored to address youths’ reasons for DV as well as reducing their substance use. PMID:23219602

    This report provides summary results of the Calendar Year (CY) 1993 As Low As Reasonably Achievable (ALARA) Program at the Pacific Northwest Laboratory (PNL). This report includes information regarding whole-body exposures to radiation, and skin contaminations. The collective whole-body radiation dose to employees during 1993 was 0.58 person-sievert (58 person-rem). This dose was 11 percent lower than the projected dose of 0.65 person-sievert (65 person-rem). The Radiation Protection Section`s Field Dosimetry Services group projected that no PNL employee`s dose would exceed 0.02 sievert (2 rem) based on dosimeters processed during the year; no worker actually exceeded the limit by the end of CY 1993. There were 15 reported cases of skin contamination for PNL employees during 1993. This number of 60 percent of the projected total of 25 cases. There were an additional 21 cases of personal-effects contamination to PNL staff: Nine of these contamination events occurred at the 324 Building, nine occurred at the 325 Building, one occurred in the 327 Building, one occurred in the 3720 Building, and one occurred in the 326 Building. Line management set numerous challenging and production ALARA goals for their facilities. Appendix A describes the final status of the 1993 ALARA goals. Appendix B describes the radiological ALARA goals for 1994. The Radiation Protection Section of the Laboratory Safety Dept. routinely perform audits of radiological ALARA requirements for specific facilities with significant potential for exposure. These ALARA audits are part of a comprehensive safety audit of the facility, designed to evaluate and improve total safety performance.

It includes descriptions of the Laboratory site, its mission, the status of its compliance with applicable environmental regulations, its planning and activities to maintain compliance, and a comprehensive review of its environmental protection, surveillance and monitoring programs. Ames Laboratory is located on the campus of Iowa State University (ISU) and occupies twelve buildings owned by the Department of Energy (DOE). The Laboratory also leases space in ISU owned buildings. Laboratory activities involve less than ten percent of the total chemical use and approximately one percent of the radioisotope use on the ISU campus. In 1996, the Office of Assurance and Assessment merged with the Environment, Safety and Health Group forming the Environment, Safety, Health and Assurance (ESH and A) office. In 1996, the Laboratory accumulated and disposed of wastes under US Environmental Protection Agency (EPA) issued generator numbers. Ames Laboratory submitted a Proposed Site Treatment Plan to EPA in December 1995. This plan complied with the Federal Facilities Compliance Act (FFCA). It was approved by EPA in January 1996. The consent agreement/consent order was issued in February 1996. Pollution awareness, waste minimization and recycling programs, implemented in 1990 and updated in 1994, continued through 1996. Included in these efforts were a waste white paper and green computer paper recycling program. Ames Laboratory also continued to recycle salvageable metal and used oil, and it recovered freon for recycling. All of the chemical and nearly all of the radiological legacy wastes were properly disposed by the end of 1996. Additional radiological legacy waste will be properly disposed during 1997.

    During calendar year 1989, EG G Idaho completed the initial procurement and implementation of a major new Computer-Aided Engineering (CAE) system. Seventy new workstations and associated engineering applications were installed over 100 personal computers (PCs) were integrated into the environment, and communications links to the IBM mainframes and the Cray supercomputer were established. The system achieves integration through sophisticated data communications and application interfaces that allow data sharing across the entire environment. Applications available on the system facilitate engineering relate to full three-dimensional (3-D) piping, heating/ventilating/air conditioning (HAVC), structural and steel design, solids modeling and analysis, desktop publishing, design and drafting, and include automated links to various analysis codes on the Cray supercomputer. The system also provides commonly used engineering tools such as spreadsheets, language compilers, terminal emulation, and file transfer facilities. Although difficult to quantify, recent information has shown that projected annual productivity improvement to the Idaho National Engineering Laboratory (INEL) will be in excess of $2,000,000. This improvement will be generated in a variety of areas including improvement in the efficiency of individual users, checkplot production, data management, file transfers, plotting. design-analysis interfaces, and the benefit of full 3-D design. Current plans call for a significant expansion of the CAE system in 1990 with continued expansion through 1993. Additional workstations, system software and utilities, networking facilities and applications software will be procured and implemented. More than one hundred people will receive training on the various application packages during 1990. Efforts to extend networking throughout the INEL will be continued. 2 refs.

    Background Mortality in children under five years has been widely studied, whereas mortality at 5–9 years has received little attention. Using unique data from national registers in three Nordic countries, we aimed to characterize mortality directionality in children aged 0 to 9 years. Methods and Findings The cohort study included all children born in Denmark from 1973 to 2008 (n = 2,433,758), Sweden from 1973 to 2006 (n = 3,400,212), and a random sample of 89.3% of children born in Finland from 1987 to 2007 (n = 1,272,083). Children were followed from 0 to 9 years, and cumulative mortality and mortality rates were compared by age, gender, cause of death, and calendar periods. Among the 7,105,962 children, there were 48,299 deaths during study period. From 1981–1985 to 2001–2005, all-cause mortality rates were reduced by between 34% and 62% at different ages. Overall mortality rate ratio between boys and girls decreased from 1.25 to 1.21 with the most prominent reduction in children aged 5–9 years (from 1.59 to 1.19). Neoplasms, diseases of the nervous system and transport accidents were the most frequent cause of death after the first year of life. These three leading causes of death declined by 42% (from 6.2 to 3.6 per 100,000 person years), 43% (from 3.7 to 2.1) and 62% (from 3.9 to 1.5) in boys, and 25% (from 4.1 to 3.1 per 100000 person years), 42% (from 3.4 to 1.9) and 63% (from 3.0 to 1.1) in girls, respectively. Mortality from neoplasms was the highest in each age except infants when comparing cause-specific mortality, and half of deaths from diseases of the nervous system occurred in infancy. Mortality rate due to transport accidents increased with age and was highest in boys aged 5–9 years. Conclusions Mortality rate in children aged 0–9 years has been decreasing with diminished difference between genders over the past decades. Our results suggest the importance of further research on mortality by causes of neoplasms, and causes of transport

  6. Combinatorics of the christian calendar (French Title: Combinatoire du calendrier chretien)

    NASA Astrophysics Data System (ADS)

    Paoli, J.

    2005-09-01

    The main goal of the Roman calendar of Julius Caesar was to fix the dates of the seasons by introducing leap years. Christians adopted this calendar, but associated to it the Judaic cycle of the week for reference to some events of Christ's life. This paper defines some problems which arose from the empiric association of the two chronological scales. Solutions to these problems can be obtained by exhaustive computer generated enumeration. Here we will solve these problems by matrix analysis which displays all arithmetical operations involved thereby making the solutions verifiable.

  7. Trends in utilization and survival after autologous hematopoietic cell transplantation in North America from 1995 to 2005: Significant improvement in survival for lymphoma and myeloma during a period of increasing recipient age

    2013-01-01

    Autologous hematopoietic cell transplantation (autoHCT) is used for relapsed and recurrent malignant disorders and as part of initial therapy for selected malignancies. This study describes changes in utilization, techniques and survival in a population–based cohort including 68,404 patients who underwent first autoHCT in a US or Canadian center, 1994–2005, and were reported to the Center for International Blood and Marrow Transplant Research (CIBMTR). The highest annual mean autoHCTs performed (average 6,948 annually) occurred during 1996–1999, with a subsequent decrease (average 4,783 annually), mainly due to less autoHCTs for breast cancer. However, the annual mean of autoHCTs increased from 5,278 annually in 1994–1995 to 5,459 annually in 2004–2005, reflecting increased utilization for multiple myeloma (MM), non-Hodgkin (NHL) and Hodgkin lymphoma (HL). Despite an increase in the median age from 44 to 53 years, there has been a significant improvement in OS from 1994 to 2005 for patients with chemotherapy-sensitive relapsed NHL (Day +100 OS: 85 to 96%; 1 year OS: 68 to 80% P<0.001) and chemotherapy-sensitive MM (Day +100 OS: 96 to 98%; 1 year OS: 83 to 92% P<0.001). The OS improvement was most pronounced in middle aged (>40 years) and older (>60 years) individuals. PMID:23660172

  10. The age of peak performance in Ironman triathlon: a cross-sectional and longitudinal data analysis

    PubMed Central

    2013-01-01

    Background The aims of the present study were, firstly, to investigate in a cross-sectional analysis the age of peak Ironman performance within one calendar year in all qualifiers for Ironman Hawaii and Ironman Hawaii; secondly, to determine in a longitudinal analysis on a qualifier for Ironman Hawaii whether the age of peak Ironman performance and Ironman performance itself change across years; and thirdly, to determine the gender difference in performance. Methods In a cross-sectional analysis, the age of the top ten finishers for all qualifier races for Ironman Hawaii and Ironman Hawaii was determined in 2010. For a longitudinal analysis, the age and the performance of the annual top ten female and male finishers in a qualifier for Ironman Hawaii was determined in Ironman Switzerland between 1995 and 2010. Results In 19 of the 20 analyzed triathlons held in 2010, there was no difference in the age of peak Ironman performance between women and men (p > 0.05). The only difference in the age of peak Ironman performance between genders was in ‘Ironman Canada’ where men were older than women (p = 0.023). For all 20 races, the age of peak Ironman performance was 32.2 ± 1.5 years for men and 33.0 ± 1.6 years for women (p > 0.05). In Ironman Switzerland, there was no difference in the age of peak Ironman performance between genders for top ten women and men from 1995 to 2010 (F = 0.06, p = 0.8). The mean age of top ten women and men was 31.4 ± 1.7 and 31.5 ± 1.7 years (Cohen's d = 0.06), respectively. The gender difference in performance in the three disciplines and for overall race time decreased significantly across years. Men and women improved overall race times by approximately 1.2 and 4.2 min/year, respectively. Conclusions Women and men peak at a similar age of 32–33 years in an Ironman triathlon with no gender difference. In a qualifier for Ironman Hawaii, the age of peak Ironman performance remained unchanged across years. In contrast, gender

    Keller, S.L.

    1995-08-01

    This report provides summary results of the Calendar Year (CY) 1994 As Low As Reasonably Achievable (ALARA) Program performance at the Pacific Northwest Laboratory (PNL). This report includes data regarding performance in the area of personnel exposures to radiation, skin contaminations, control of contaminated areas, minimization of radioactive waste, and control of radioactive releases. In CY 1994: (1) The collective total effective dose equivalent to PNL employees during 1994 was 55 person-rem. The Field Dosimetry Services of the Radiological Control Department, Technical Support Section, projected that no PNL employee`s dose would exceed 2 rem based on dosimeters processed during the year; no worker actually exceeded the projection-by the end of CY 1994. The maximum dose to any individual was 1.11 rem. (2) There were 34 instances of skin and personal-clothing contamination events for PNL employees during 1994. Eighteen of these contamination events occurred at the 324 Building; eleven occurred at the 325 Building; two occurred in the 327 Building; one occurred in the 326 Building; one occurred in the 3708 Building; and one occurred in the RTL Building. (3) PNL facilities contained 12 Airborne Radioactivity Areas, and 60 Contamination Areas and High Contamination Areas. The area of the Airborne Radioactivity Areas was 383 m{sup 2}(4125 ft{sup 2}). The area of the Contamination Areas was 5290 m{sup 2}(56,947 ft{sup 2}). The area of the High Contamination Areas was 266 m{sup 2}(2863 ft{sup 2}). (4) PNL disposed of 10.5 m{sup 3}(371 ft{sup 3}) of compacted low level waste. Also disposed was 423 m{sup 3} (14,949 ft{sup 3}) of noncompacted low level and mixed waste that was not subject to volume reduction. The total radioactivity of the disposed waste was 1217 Ci. (5) PNL facilities released 165.2 Ci of noble gas, 3.0E-5 Ci of airborne particulate radioactive material, and 12.2 Ci of tritium to the environment.

    2013-01-01

    Purpose Our study aimed to examine the relationship between intelligence and health-related quality of life (HRQOL) in children (6-13 years old) diagnosed as having a brain tumor. Materials and Methods We administered a Korean version of the Wechsler Intelligence Scale for Children-III, the Pediatric Quality of Life Inventory, version 4.0 (PedsQL), the Korean version of the Parenting Stress Index-Short Form, and the Korean Version of the Parenting Sense of Competence (K-PSOC) scale before or after initial radiotherapy (T1) and after treatment termination (T2). In total, 13 patients completed both the T1 and T2 interviews. Results Scores significantly declined between T1 and T2 on the full-scale intelligence quotients (FIQ), verbal intelligence quotients (VIQ), performance intelligence quotients (PIQ), similarity and coding tests, as well as the K-PSOC, which measures parental anxiety. FIQ scores at T1 were correlated with the self-reported PedsQL total scores (r=0.739) and the parent proxy-report PedsQL scores for school functioning (r=0.706) at T2. Also, the FIQ scores at T2 were correlated with the self-reported PedsQL total scores (r=0.748) and scores for physical health (r=0.728) at T2. Conclusion The cognitive ability and intelligence level of the patients significantly declined between on and off treatment periods, and higher intelligence functioning at both on and off treatment was correlated with long-term higher HRQOL. Further investigations that monitor intelligence, HRQOL and parenting stress over a longer period, using a greater number of participants, are needed. PMID:23364961

  13. Aging blepharoplasty.

    PubMed

    Cho, Inchang

    2013-09-01

    In performing upper blepharoplasty in the elderly, looking younger and keeping the eyelids harmonious with the rest of the face have to be achieved at the same time. The most important goal in upper blepharoplasty for aging is correcting the drooping upper eyelid skin, and in this process, the surgeon may or may not create a double eyelid fold. The pros and cons have to be fully discussed with the patient, but the author personally prefers creating a double fold unless the patient refuses, because it is efficient in correcting and preventing further drooping of the skin. In most patients, the brow is elevated to compensate for the drooping eyelid, and when the drooping is corrected, brow ptosis may ensue. The surgeon has to prepare for these consequences before performing the procedure, and estimate the exact amount of skin to be excised. In the elderly, the skin and the orbicularis oculi muscle is thin, with a decreased amount of subcutaneous fat and retro-orbicularis oculi fat, and in most cases, excision of the skin alone is enough to correct the deformity. Removing large portions of soft tissue may also prolong the recovery period. Unlike younger patients, the lower skin flap should not be stretched too much in the elderly, as it may create an aggressive looking appearance. A few wrinkles in the lower flap should remain untouched to create a natural look. In this article, the author's own methods of performing an aging blepharoplasty are described specifically, with a step-by-step guide and surgical tips. PMID:24086798

    2016-01-01

    Objectives There are very little data on pre-excitation syndrome (PS) in the elderly. We investigated the influence of advancing age on clinical presentation, treatment and long-term outcome of PS. Setting Single-centre retrospective study of patient files. Participants In all, 961 patients (72 patients ≥60 years (mean 68.5±6), 889 patients <60 years (mean 30.5±14)) referred for overt pre-excitation and indication for electrophysiological study (EPS) were followed for 5.3±5 years. Usual care included 24 h Holter monitoring, echocardiography and EPS. Patients underwent accessory pathway (AP) ablation if necessary. Primary and secondary outcome measures Occurrence of atrial fibrillation (AF) or procedure-induced adverse event. Results Electrophysiological data and recourse to AP ablation (43% vs 48.5%, p=0.375) did not significantly differ between the groups. Older patients more often had symptomatic forms (81% vs 63%, p=0.003), history of spontaneous AF (8% vs 3%, p=0.01) or adverse presentation (poorly tolerated arrhythmias: 18% vs 7%, p=0.0009). In multivariable analysis, patients ≥60 years had a significantly higher risk of history of AF (OR=4.2, 2.1 to 8.3, p=0.001) and poorly tolerated arrhythmias (OR=3.8, 1.8 to 8.1, p=0.001). Age ≥60 years was associated with an increased major AP ablation complication risk (10% vs 1.9%, p=0.006). During follow-up, occurrence of AF (13.9% vs 3.6%, p<0.001) and incidence of poorly tolerated tachycardia (4.2% vs 0.6%, p=0.001) were more frequent in patients ≥60 years, although frequency of ablation failure or recurrence was similar (20% vs 15.5%, p=0.52). In multivariable analysis, patients ≥60 years had a significantly higher risk of AF (OR=2.9, 1.2 to 6.8, p≤0.01). Conclusions In this retrospective monocentre study, patients ≥60 years referred for PS work up appeared at higher risk of AF and adverse presentation, both prior and after the work up. These results suggest that, in elderly

  6. The neural architecture of expert calendar calculation: a matter of strategy?

    PubMed

    Fehr, Thorsten; Wallace, Gregory L; Erhard, Peter; Herrmann, Manfred

    2011-08-01

    Savants and prodigies are individuals with exceptional skills in particular mental domains. In the present study we used functional magnetic resonance imaging to examine neural correlates of calendar calculation in two individuals, a savant with Asperger's disorder and a self-taught mathematical prodigy. If there is a modular neural organization of exceptional performance in a specific mental domain, calendar calculation should be reflected in a considerable overlap in the recruitment of brain circuits across expert individuals. However, considerable individual differences in activation patterns during calendar calculation were noted. The present results indicate that activation patterns produced by complex mental processing, such as calendar calculation, seem to be influenced strongly by learning history and idiosyncratic strategy usage rather than a modular neural organization. Thus, well-known individual differences in complex cognition play a major role even in experts with exceptional abilities in a particular mental domain and should in particular be considered when examining the neural architecture of complex mental processes and skills.
