A part of life. The Hindu view.  

PubMed

A leading social anthropologist and founder of the Center for Advanced Studies in Sociology at Delhi University presents a Hindu view on teachings about birth and population control. The article states that Hinduism accepts the sacred scriptures of the "shruti" whom are respected authorities revealed by God to man and the "smrities" which are divine recollections of revealed truth. Shruti have greater authority, and divine works include the vedas or hymns of the Indo-Aryans to their gods. Dharma shastras are smriti and provide legal opinion on religion and social matters. Learned men interpret these scriptures for the common people. The Hindu scriptures do not mention anything contrary to birth control. Sex is an accepted way of life without prudery. Householdership is said to be one of the universal stages of life. The Kama Sutra, written by Vatsyayana in the early fourth century, and other works digress on the celebration of love. Human lovemaking is celebrated in panels appearing in the Khajuraho temples in Madhya Pradesh and in temple chariots in south India. Ayurvedic medicine and literature on erotics explains many devices for preventing conception. High Hindu castes are reported in this article as placing great emphasis on patrilineage and the need for sons to continue the male line. Adoption or limiting family size to 1-2 children is resorted to when there is no apparent male heir. This emphasis on sons contributes to female infanticide and neglect of daughters. The belief in "karma" or reincarnation was once considered to be antagonistic to the practice of contraception and birth control. Education and literacy have increased the acceptance of modern contraception. Awareness of population growth as a potential problem is prevalent among educated Hindus. The government of Mysore was the first in the world to establish a birth control clinic. The National Planning Committee of the Indian National Congress advocated family planning and birth limiting since 1935. PMID:12345274

Hindu and Buddhist children, adolescents, and families.  

PubMed

The language of psychotherapy that focuses on the individual may be problematic for Hindu and Buddhist families. The focus on child and adolescent development as a separation-individuation process that moves the child into an independent life with individual goals may run contrary to family cultural values and to the Hindu and Buddhist views of interconnectedness. For the Hindu family, however, when therapy can be seen as being compatible with an evolution toward the higher self and is consistent with the shared sense of family belonging, the goals can be complementary. With the fundamental views in Buddhism that suffering derives from emotional and conceptual misunderstandings and from the resultant actions, and that change is necessary to relieve that suffering, therapy and practice may share goals. The spiritual teachings can work alongside the therapeutic work, and the improved functioning is also spiritual growth. PMID:14723309

Health and health care--a Hindu perspective.  

PubMed

In the Hindu tradition, 'health' means the continued maintenance of the best possible working of the human body under normal, and sometimes even abnormal, environmental conditions. Hindu religious teaching on healthy living and ethical considerations culminate in spiritual objectives if the injunctions contained in the system are followed. Hatha yoga is a system of bodily care that is conducive to such health, which also corrects disease via the regulation of muscular action and in other ways. Other systems of medicine, such as Ayurveda and other traditional systems in Hindu culture, have been devised for the good of humanity. It is, however, the holistic approach to health in Hinduism that calls attention to such causes of ill health as climatic extremes, bacterial attack, nutritional deviance, stress, and other forms of emotional imbalance. A state of good health is within the reach of most persons if they cultivate habits that are conducive to physical and spiritual well-being. The concept of preventive medicine is probably also based on the tenet that the attainment of good health is a religious duty, and corresponding injunctions are found in abundance in Hindu scriptures. It is not the training of students in the medical profession that is most important for health care, but rather their concern for health and their willingness to apply themselves to the observation of the rules they would wish their patients to observe.

Background: A retrospective analysis of all cancer patients attending the radiotherapy outpatient department (OPD) of a single unit during the period of January 2005 till December 2006 was conducted to know the geographical distribution and incidence of the most common cancers, their stage of presentation, treatment compliance among the patients and follow-up. Materials and Methods: A total of 4,484 patients were registered in the Institute of Medical Sciences, Banaras Hindu University during the period of January 2005- December 2006; of which 1,975 registered in an individual unit were included for the retrospective analysis. Results: Most of the patients hailed from the various districts of UP and Bihar. Females outnumbered males with a ratio of 1.33:1. Females mostly belonged to the age group of 40-59 years; whilst males were a decade older. Major cancer sites in females were cervix and breast followed by head and neck. Leading cancer sites in males were head and neck, brain, bone, soft tissue and lung. Most of the cases presented in advanced stage of disease (74%). Squamous cell carcinoma was the most common histopathology (56%). A significant proportion of patients defaulted after undergoing preliminary investigations (16%). Only 53.9% of females and 58.5% of males took treatment out of which 68% and 63% completed the prescribed treatment. Compliance with follow-up was poor. Conclusions: The outcome of this study will significantly help us to define region specific strategies needed for cancer management in eastern Uttar Pradesh. PMID:24175765

'The History of Hindu Chemistry' is one of the rare, important books published in twentieth century.

The book in two volumes is in English and has achieved international recognition. The work became the cause of enlightening people specially, the Westerners about Indian Alchemy which, they were till then unaware of. In a way, 'globalization' of the concepts of Rasashastra has its starting point in the works of Sir P.C.Ray. The author has touched almost every area of Rasashastra of course, from the standpoint of modern Chemistry. A critical analysis of his contributions, the narration of the contents of the book are detailed in the paper. PMID:22557428

Contradictions in consciousness or variations in tradition: Hindu women in the South African diaspora.  

PubMed

The introductory section of this paper reviews previous studies of the Indian diaspora to show their lack of attention to gender issues. While ideals of Hindu fundamentalism and social conditions imposed by caste are unlikely to be recreated in South Africa, it is proposed that Hindu women in South Africa are custodians of Hindu values. The paper goes on to present a brief history of middle and upper-class Hindu women in South Africa to place them within the context of the Indian diaspora. After describing the fieldwork and methodology (data were gathered from extensive interviews with 20 women representing the four major linguistic groups currently living in Durban), some of the distinctive characteristics of women's experiences and the problems these present because they are either contradictions or variations of conditions in India are discussed. The study then demonstrates that the individual choices made by the women are inconsistent with the apartheid notions of unambiguous social boundaries and also challenge the opposing Marxist perspective that ethnic consciousness is false. It is concluded that cultural adornments and self-imposed limitations on travel and socialization publicize status and ethnic identity and continuity with tradition. Hindu women in South Africa emphasize this continuity through personal beliefs or through the way they present themselves in public. PMID:12292073

Chigger mites (Acari, Trombiculidae) parasitizing small mammals in the Eastern Hindu Kush and some other Afghan areas.  

PubMed

Chigger mites of Afghanistan were studied on the base of collections made in Eastern and Central Hindu Kush, Kabul, and some other localities. Fifteen chigger species parasitizing nine species of Rodentia, two species of Lagomorpha, and one species of Soricomorpha were found, including 13 species which were not previously recorded in Afghanistan. Eco-geographical variability is observed in Shunsennia oudemansi: Individuals of this species from high-mountain localities of Eastern Hindu Kush are characterized by larger values of most morphometric characters than the specimens collected in Kabul. Vertical and horizontal distribution of chiggers and chigger-host relationships in Eastern Hindu Kush is discussed. Comparison of our data with that on chigger fauna in the region of Tirich Mir clearly demonstrates the role of the Eastern Hindu Kush main ridge as a border between different chigger faunas.

Exploring Hindu Indian emotion expressions: evidence for accurate recognition by Americans and Indians.  

PubMed

Subjects were presented with videotaped expressions of 10 classic Hindu emotions. The 10 emotions were (in rough translation from Sanskrit) anger, disgust, fear, heroism, humor-amusement, love, peace, sadness, shame-embarrassment, and wonder. These emotions (except for shame) and their portrayal were described about 2,000 years ago in the Natyasastra, and are enacted in the contemporary Hindu classical dance. The expressions are dynamic and include both the face and the body, especially the hands. Three different expressive versions of each emotion were presented, along with 15 neutral expressions. American and Indian college students responded to each of these 45 expressions using either a fixed-response format (10 emotion names and "neutral/no emotion") or a totally free response format. Participants from both countries were quite accurate in identifying emotions correctly using both fixed-choice (65% correct, expected value of 9%) and free-response (61% correct, expected value close to zero) methods.

Directional migration in the Hindu castes: inferences from mitochondrial, autosomal and Y-chromosomal data.  

PubMed

Genetic, ethnographic, and historical evidence suggests that the Hindu castes have been highly endogamous for several thousand years and that, when movement between castes does occur, it typically consists of females joining castes of higher social status. However, little is known about migration rates in these populations or the extent to which migration occurs between caste groups of low, middle, and high social status. To investigate these aspects of migration, we analyzed the largest collection of genetic markers collected to date in Hindu caste populations. These data included 45 newly typed autosomal short tandem repeat polymorphisms (STRPs), 411 bp of mitochondrial DNA sequence, and 43 Y-chromosomal single-nucleotide polymorphisms that were assayed in more than 200 individuals of known caste status sampled in Andrah Pradesh, in South India. Application of recently developed likelihood-based analyses to this dataset enabled us to obtain genetically derived estimates of intercaste migration rates. STRPs indicated migration rates of 1-2% per generation between high-, middle-, and low-status caste groups. We also found support for the hypothesis that rates of gene flow differ between maternally and paternally inherited genes. Migration rates were substantially higher in maternally than in paternally inherited markers. In addition, while prevailing patterns of migration involved movement between castes of similar rank, paternally inherited markers in the low-status castes were most likely to move into high-status castes. Our findings support earlier evidence that the caste system has been a significant, long-term source of population structuring in South Indian Hindu populations, and that patterns of migration differ between males and females.

Geometry of the Pamir-Hindu Kush intermediate-depth earthquake zone from local seismic data  

NASA Astrophysics Data System (ADS)

We present new seismicity images based on a two-year seismic deployment in the Pamir and SW Tien Shan. A total of 9532 earthquakes were detected, located, and rigorously assessed in a multistage automatic procedure utilizing state-of-the-art picking algorithms, waveform cross-correlation, and multi-event relocation. The obtained catalog provides new information on crustal seismicity and reveals the geometry and internal structure of the Pamir-Hindu Kush intermediate-depth seismic zone with improved detail and resolution. The relocated seismicity clearly defines at least two distinct planes: one beneath the Pamir and the other beneath the Hindu Kush, separated by a gap across which strike and dip directions change abruptly. The Pamir seismic zone forms a thin (approximately 10 km width), curviplanar arc that strikes east-west and dips south at its eastern end and then progressively turns by 90° to reach a north-south strike and a due eastward dip at its southwestern termination. Pamir deep seismicity outlines several streaks at depths between 70 and 240 km, with the deepest events occurring at its southwestern end. Intermediate-depth earthquakes are clearly separated from shallow crustal seismicity, which is confined to the uppermost 20-25 km. The Hindu Kush seismic zone extends from 40 to 250 km depth and generally strikes east-west, yet bends northeast, toward the Pamir, at its eastern end. It may be divided vertically into upper and lower parts separated by a gap at approximately 150 km depth. In the upper part, events form a plane that is 15-25 km thick in cross section and dips sub-vertically north to northwest. Seismic activity is more virile in the lower part, where several distinct clusters form a complex pattern of sub-parallel planes. The observed geometry could be reconciled either with a model of two-sided subduction of Eurasian and previously underthrusted Indian continental lithosphere or by a purely Eurasian origin of both Pamir and Hindu Kush seismic zones, which necessitates a contortion and oversteepening of the latter.

velocities measured in the Pamir and surrounding regions show a total of ~30 mm/yr of northward relative motion between stable Pakistan and Eurasia. The convergence budget is partitioned into 10-15 mm/yr of localized shortening across the Trans-Alai Thrust, which bounds the Pamir on the north, consistent with southward subduction of intact lithosphere. Another 10-15 mm/yr of shortening is distributed across the Chitral Himalaya and Hindu Kush, suggesting that Hindu Kush seismicity might be related to northward subduction of Indian lithosphere. Modest shortening at <5 mm/yr occurs north of the Trans-Alai Thrust, across the South Tien Shan and between the Ferghana Valley and Eurasia. Negligible north-south shortening occurs within the high Pamir, but as much as 5 mm/yr, and perhaps 10 mm/yr, of east-west extension occurs within this region. This extension is matched by a comparable amount of east-west shortening in the Tajik Depression. The localization of shortening to the margins of the Pamir combined with observations of distributed internal extension implies that the east-west vertically averaged, horizontal compressive normal stress is smaller than the north-south compressive stress.

Thandai and chilam: traditional Hindu beliefs about the proper uses of Cannabis.  

PubMed

Hindu beliefs about appropriate use of cannabis illustrate the capacity of cultural systems to order and direct the course of complex phenomenal events. Cannabis manifests diverse and contradictory effects. These depend not only on dose, frequency and route of administration, but also on subjective and cultural contexts (e.g., Pihl, Shea & Costa 1979). It may very well be that the contradictory results of modern research investigations on cannabis stem from the intricacy of these interactions. Given the current state of the art, paradigms of research methodology may very well be inadequate to develop an understanding of such a paradoxical drug. The Hindu cultural system, on the other hand, accommodates the ambiguities of cannabis through its own complex nature. It provides diverse niches through which antithetical effects of the drug are expressed. Cannabis is said to both interfere with motivation to work and facilitate it. A closer examination reveals that these actions are probably related to the way in which this motivation toward action is defined, and the level of use of the drug. While cannabis appears to interfere with execution of highly complex tasks and the long-range planning that accompanies them, it may facilitate concentrated focus on repetitive endeavors. In some commonsense way, it may be quite simply that it changes a user's sense of time and the span of the present as well as the sense of relative importance of present and future. So long as an individual is under the influence of this effect (and living in the context that s/he has structured as a result of it), the urgency of accomplishment in the Western sense is diminished. The Hindu belief system accommodates this by prescribing use in such a way that this effect becomes beneficial. A key factor is that low potency preparations (bhang, thandai) are available. It allows individuals with complex life tasks, goals and obligations to indulge in moderation. The drug is also taken in a ritualized context, facilitating concentration and relaxation. It is taken at times, such as in the evening or on holidays, in which focus on the immediate present is a welcome change. Use of the more potent preparations (ganja, charas) is not condoned for this group. Above all, moderation is enjoined and popular folk belief warns of the potential problems of excess. Ganja and charas are regarded more ambivalently as poisons or semipoisons.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:3903086

Remarkable recurrence of M~7- intermediate-depth earthquakes beneath the Hindu Kush  

NASA Astrophysics Data System (ADS)

Recurrent activity of intermediate-depth earthquakes (h60-300km) is remarkable beneath the Hindu Kush, the western vicinity of the Himalayas where the Indian plate is colliding against the Eurasian plate. Utsu (1994) pointed out that beneath the Hindu Kush (around 36.4 degrees north, 70.8 degrees east, h220km) M7-class earthquakes had recurred five times about every nine years; 1956 (mb6.5), 1965 (mb7.5), 1974 (mb7.1), 1983 (Mw7.4), and 1993 (Mw7.0). Moreover, a Mw7.3 earthquake occurred at the same place in 2002. In order to examine whether these are characteristic earthquakes or not and to discuss the mechanism of their occurrence, we first relocated the 1956 main shock and the earthquakes beneath the Hindu Kush during the period from 1964 through 2007 by the Hurukawa's (1995) Modified Joint Hypocenter Determination method. The main shocks and aftershocks of later five large events are included in these events. Out of 4,103 earthquakes with depth range of 100-300km, 3,372 hypocenters were well relocated. The results show (1) a southward steeply dipping hypocenter distribution around the depth of 190 to 220 km, while the overall intermediate-depth seismicity shows almost vertical shape with slight northward-dipping. (2) The 1956, 1965, 1974, and 1983 main shocks occurred at almost the same place. The 1993 main shock took place about 15 km southeast of the formers. The 2002 main shock took place about 30 km northwest of the earlier four events. (3) These five hypocenters are within about 35 km alignment striking in the ESE-WNW direction. Focal mechanisms of all the five large earthquakes are very similar, showing ESE-WNW running and southward-dipping high-angle reverse faulting with a down-dip tension. We investigated their rupture processes by inversion analyses of teleseismic body-waves (Kikuchi and Kanamori, 2003) and obtained the following results: (1) Main slips of the 1965, 1974, and 1983 events existed almost at the same place. (2) The 1993 rupture propagated toward northwest and deep direction. The largest slip took place on the northeastern deep area near the initial rupture point. (3) The 2002 largest slip took place about 40 km southeast from the initial rupture point. (4) Concerning Mw and slip amounts, the 1965 (Mw 7.6/4.9m) event was the largest, the 1983 (7.4/2.7m) and 2002 (7.3/1.4m) ones were also large, but the 1974 (7.1/0.8m) and 1993 (7.1/0.8m) events were relatively small. Thus, these five large earthquakes are not considered to be exactly characteristic earthquakes, although their asperities were overlapping considerably. However, their rupture zones concentrated within a very narrow area, and if we take errors of hypocenter location and waveform analyses into account, it may be possible that they were repeating ruptures of an identical fault plane. Beneath the Hindu Kush, nearly vertical slab is inferred to exist down to 300 km or so, by seismic tomography. Probably there exists a certain mechanism of concentration of slab-pull tensional force to a narrow zone (h200-220km), which controls a surprisingly regular recurrence of M7-class earthquakes with a remarkably short repeat time. The next event may be imminent in this region.

Anasakti, the Hindu ideal, and its relationship to well-being and orientations to happiness.

Anasakti, a Sanskrit term for traits like non-attachment, equipoise, selfless duty orientation, and effort in the absence of concern for the outcome, can be regarded as a Hindu-ideal cluster of personality traits. The relationship of Anasakti with well-being and the three distinct happiness orientations was explored through a study of 676 college students and a sample of 65 yogic practitioners in India. The findings revealed that the yogic practitioners were markedly higher in Anasakti than the secular population. For the yogic population, there was a large correlation between Anasakti and the Orientation to Meaningful Life, and it accounted for more than 20% of the variance in the regression of Anasakti against all the measures of well-being. The yogic population's scores also correlated with several other measures of well-being. The scores of the secular population were less strongly related to the well-being scores; though, several correlation coefficients were statistically significant. PMID:20953711

Seismicity of the Pamir and Hindu Kush: new constraints on regional tectonics  

NASA Astrophysics Data System (ADS)

The Pamir and Hindu Kush regions in Central Asia host the most active zone of intracontinental seismic activity at intermediate depths (up to nearly 300km) in the world, which is still poorly understood in terms of its detailed structure and, most importantly, its origin. Being situated far from any typical subduction zone setting and displaying a change in its polarity along strike, this seismically active zone has been interpreted in numerous ways, e.g. as a single slab of Indian lithosphere originally subducted northwards which was subsequently overturned in its eastern part or as two adjacent subduction zones of opposing polarity. Several key questions concerning this region, among them the nature of subducted material (oceanic or continental?), the mechanism behind the generation of these intermediate-depth earthquakes and the region's tectonic framework have not been answered as of yet. As the seismological subpart of the TIPAGE project, we deployed a network of 40 seismometer stations for a total duration of two years (2008-2010) in Tajikistan and southern Kyrgyzstan, covering the Pamir mountains and surroundings. Complemented with two more temporary deployments and additional data from several permanent networks in adjacent areas, this constitutes a seismic dataset of unprecedented station density for this part of Central Asia. Showing the distribution of more than 9,500 earthquakes located with a highly precise double-difference method based on the cross-correlation of individual traces, fault plane solutions for shallow and deep earthquakes as well as preliminary results from traveltime tomography, we can resolve the exact geometry of the deep seismic zone and draw further constraints on the tectonic processes active in the region. The S-shaped region of intermediate-depth seismicity is clearly subdivided into two separate parts, hence termed Hindu Kush and Pamir seismic zones. The Hindu Kush seismic zone strikes due east-west at a latitude of about 36.4°N. Depth sections show that earthquakes extend from depths of 50 to around 250 km along a planar, steeply northward-dipping structure. Earthquakes are most frequent in the depth range from 180 to 220 km, whereas there is a seismic "gap" at about 150 km depth. Intriguingly, the Hindu Kush seismic zone features a small-scale reversal of dip polarity in its lower part (beneath the 150km gap) towards its eastern termination. The Pamir seismic zone forms an arc, the strike of which varies by 90 degrees from north-south at its southwestern end (where it borders the Hindu Kush seismic zone) to east-west at its eastern termination. The dip direction of the structure changes from due east to due south from west to east. Seismic activity outlines a narrow (10-15 km) Wadati-Benioff zone displaying a constant dip of about 50 degrees all along its extent. Whereas seismic activity ceases at depths of 130-150 km in the east, the south-western part of the zone shows earthquakes reaching depths of up to 240 km that outline a vertical structure beneath 150 km depth. All along the arc, the upper termination of seismic activity is found at depths of 60-80 km, leaving a gap to shallow seismic activity which is confined to the uppermost 20-25 km. Intermediate-depth earthquakes in the eastern Pamir and the low-velocity zone they are situated within can be linked with shallow seismic activity along the Main Pamir Thrust (MPT) further north, which implies ongoing intracontinental southward subduction, presumably of continental material, in the Alai Valley. Tracing the surface expression of the deep earthquakes along the Pamir arc, towards the southwest, proves complicated. It is possible that the western part of the Pamir seismic zone is linked to the ongoing east-west compression in the Tajik Depression seen by GPS, but evidence is scarce. Shallow seismic activity concentrates along the Pamir's northern rim (MPT) and in its western part, wheras the eastern Pamir is seismically quiet. Fault-plane solutions obtained by moment tensor inversion show predominance of sinistral st

Contrasted evolution of glacial lakes along the Hindu-Kush Himalaya mountain range between 1990 and 2009  

NASA Astrophysics Data System (ADS)

In this study, we present the first assessment of glacial lake distribution and evolution in the Hindu Kush Himalaya (HKH). Seven sites have been selected between Bhutan and Afghanistan, to capture the climatic variability along the 2000-km long mountain range. For each site, glacial lakes have been mapped with LANDSAT satellite imagery acquired in 1990, 2000 and 2009, using an automatic classification. In the East (India, Nepal and Bhutan) glacial lakes are bigger and more numerous than in the West (Pakistan, Afghanistan), and have grown continuously between 1990 and 2009 by 20% to 65%. Conversely, during the same period, the glacial lake coverage has shrunk in the Hindu Kush (-50%) and the Karakorum (-30%). This east/west pattern of lake changes seems in agreement with sparse glaciological measurements that suggest less (or even no) ice loss in the western part of the HKH.

The Status of Glaciers in the Hindu Kush-Himalayas from satellite data  

NASA Astrophysics Data System (ADS)

In contrary to general glacier retreat in this vast Hindu Kush-Himalayan (HKH) region, some of the glaciers are advancing in the Karakorum (Hewitt, 1985). To understand the climate change impacts on glaciers, it is crucial to update the glacier status. The bigger concern in the HKH region, however, is the lack of long-term information on glaciers at the regional level for any kind of credible baseline or assessment of change. Hence to provide the up to date glacier information the glacier inventory was carried out using a single source satellite images of latest date so far possible. The present mapping of glaciers is the first effort of homogeneous glacier inventory of entire Hindu Kush-Himalayan region, which made the first time reporting of glaciers from Myanmar and first generation of glacier mapping and inventory of Afghanistan and Jammu & Kashmir and Arunachal states of India for ICIMOD. For Nepal, Bhutan, Pakistan, some states of India (Himachal, Uttarakhand and Sikkim) and Ganges basin in China will be the second generation glacier mapping and inventory of ICIMOD. The inventory is based on Landsat 7 ETM+ satellite images from 2005±3 years and SRTM DEM. The methodology of semi-automatic mapping and inventory is developed and implemented in the present study for quick delivery of glacier database. A first attempt is also made to map and deliver the Clean Ice and Debris Cover glaciers data separately. The glacier parameters like Glacier ID (Watershed and GLIMS), Area (Debris Cover and Clean Ice), Elevation, Slope, Aspect, Thickness, Ice reserve and 100m Glacier Area-Altitude bins are generated. The glaciers with sizes larger than 0.02 km2 are mapped. From the entire HKH region about 54,800 glaciers are mapped with about 60,400 km2 glacier area and 6,100 km3 estimated ice reserves. It was found that the average glacier area of the HKH region is 1.10 km2 per glacier (Bajracharya and others 2011).

Glacier Debris Cover Variation in the Hindu Kush and Karakoram Himalaya  

NASA Astrophysics Data System (ADS)

Alpine glaciers in the Hindu Kush of Afghanistan and the Western Himalaya of Pakistan are heavily debris- covered and exhibit high spatial distribution and depth variability. This property of a glacier surface plays a major role in the energy balance and partially controls the ablation rate. Consequently as the GLIMS Regional Center for Southwest Asia, we wanted to determine if climate forcing and thinning glaciers would generate more debris cover that would have an influence on the mass- balance gradient. Therefore, we conducted a multi-temporal study of debris cover variation on selected glaciers using satellite imagery. Specifically, co-registered, multi-decadal satellite imagery (Landsat ETM, TM, MSS and ASTER) were orthorectified and overlaid, from which cloud-free, snow-free subareas of the glaciers were identified. Visual and quantitative comparisons were performed on 20 small glaciers and ice- cored rock glaciers in Afghanistan, and the Batura, Biafo, and Baltoro glaciers of the Karakoram, and Raikot and Buldar glaciers in the Nanga Parbat Himalaya in Pakistan. All subareas were classified using the ISODATA clustering algorithm. Comparison complexities caused by temporally irregular variations in satellite coverage through the ablation season make interpretation difficult. Nonetheless, our results indicate a general debris-cover increase through time, as would be expected in a climatic-warming scenario. For example, the small glaciers of the Hindu Kush are down-wasting and back-wasting where they are mostly clean ice, but where they are mostly debris covered the change is less visible. In the Karakoram multiple white-ice streams from ice falls flow down-glacier, interspersed with multiple high standing or ribbed medial moraines between. These medial moraines progressively converge down-glacier to form a continuous debris cover that itself looses its ribbed character and down-wastes into a chaotic terrain of hummocks, hollows, and supraglacial lakes. The white-ice streams form ogives, reticulated ice hills, ice pyramids, and smooth ice, the boundaries of which with the debris-covered ice, form distinctive spectral signatures that can be used effectively to interpret change. In general, the lower boundaries between white ice and debris-covered ice are seen to be retreating hundreds of meters up-ice whereas the thick debris-covered termini down-waste in place. An increase in debris cover with down-wasting represents a positive feedback that can accelerate down-wasting at progressively higher altitudes until thicker debris covers then results in a decrease of ablation rates.

Climate change implications for the glaciers of the Hindu-Kush, Karakoram and Himalayan region  

NASA Astrophysics Data System (ADS)

The Hindu-Kush, Karakoram Himalaya (HKKH) region has a negative average glacial mass balance despite anomalous possible gains in the Karakoram. However, changes in climate may influence the mass balance across the HKKH. We use high resolution climate modelling to analyse the implications of unmitigated climate change on precipitation, snowfall, air temperature and accumulated degree days for the Hindu Kush, Karakoram, Jammu-Kashmir, Himachal Pradesh and West Nepal regions, and East Nepal and Bhutan. In our analysis we focus on the climate drivers of change rather than the glaciological response. We find a complex regional response to climate change, with possible increases in snowfall over the western HKKH and decreases in the east. Accumulated degree days are less spatially variable than precipitation and show an increase in potential ablation in all regions. Overall, the eastern Himalayan glaciers are expected to be most sensitive to climate change due to the decreases in snowfall and increased ablation associated with warming. The eastern glaciers are therefore projected to decline over the 21st century despite increasing precipitation. The western glaciers are expected to decline at a slower rate over the 21st century as a response to unmitigated climate compared to the glaciers of the east. Importantly, the glacier response depends on important glaciological factors, such as the extent of debris cover, which may be of critical importance in moderating the response to climatic change. Decadal variability has a large effect highlighting the need for long-term observation records to fully understand the impact of climate on the glaciers of the HKKH cryosphere. Spatial variability in projected snowfall patterns are likely to be a key driver of glacier mass balance over the 21st century. Importantly, the regional trends in snowfall do not necessarily follow the trends in precipitation. A key change in the HKKH cryosphere is a switch from snowfall to rainfall in the eastern Himalaya. Although glacial mass balance is likely to be sensitive to climate change, as overall precipitation is projected to increase this may lead to an overall increase in water resources. In the west, projections suggest that glacial mass balance could respond less to climate change than those in the east. However, projection uncertainty covers a small increase to a decrease in precipitation for the western HKKH and Indus basin and as a result the water resources of the highly populated Indus region may be more vulnerable to unmitigated climate change.

Patterns of occurrence and concordance between subjective and objective hot flashes among Muslim and Hindu women in Sylhet, Bangladesh.  

PubMed

This study examined the pattern of occurrence and the rate of concordance between objective hot flashes measured by sternal skin conductance and the subjective experience of "gorom vap laga" (feeling steaming hot) among Muslim and Hindu women living in Sylhet, Bangladesh. Participants were aged 40-55, not pregnant or lactating, not using hormone therapy, and with no history of hysterectomy. Thirty women wore an ambulatory hot flash monitor for 8 h on average, from mid-morning to early evening. True positive, false negative, and false positive measures of hot flashes were examined in relation to demographic, reproductive, and lifestyle variables. On body diagrams, women were most likely to indicate hot flashes on the top of their head (64%) and upper chest (68%). The greatest number of objective hot flashes occurred during the hour of 17:00, perhaps due to the heat of the day, and the clothing and activity associated with prayer. Muslim participants demonstrated more objective hot flashes per woman than Hindu participants (1.5 vs. 0.1, P < 0.05), and Muslims had more false positive measures (86%) compared with Hindu participants (0%, P = 0.06). Among all women who reported subjective hot flashes (n = 19), the proportion of true positive scores was 19%. Overall, the frequency of objective hot flashes was low compared with reports from studies in the United States. The pattern of sweating assessed by body diagrams was not associated with variation in hot flash experience. PMID:18461600

The Mechanism of Intermediate-Depth Earthquakes in the Hindu Kush  

NASA Astrophysics Data System (ADS)

The Hindu Kush mountains, located near the borders of Afghanistan, Tajikistan, Pakistan, and China, formed from the collision of India with Eurasia beginning in the Eocene (~55 Ma). The collision resulted in the subduction of the Indian plate. The subduction history has been inferred from seismic tomography, earthquake locations, and thermal modeling. Some of these studies have suggested that the Indian plate subducted northward, started to overturn, and then gradually broke off towards the east. Earthquakes in this region occur down to ~250 km depth, but why they occur is unknown. They may be related to slab break-off or dehydration in the oceanic crust. To distinguish between these mechanisms, we investigate the rupture processes of 22 intermediate-depth earthquakes with Mw between 5.5 and 7.4 that occurred from 1991 to 2005. The ruptures tend to propagate subhorizontally. The earthquakes are located in 3 main clusters. Cluster I is located <150 km depth and has variable focal mechanism orientations. In Cluster II, which is located between 185 and 225 km depth, the focal mechanisms change their orientation gradually with the shape of the slab. Cluster III, located between 210 and 240 km depth to the east of Cluster II, is the most consistent one: most of the focal mechanisms are similar to one another and the rupture vectors tend to point outwards from the slab.

Western weather patterns and winter precipitation in the Hindu-Kush Karakoram  

NASA Astrophysics Data System (ADS)

In this work we study western weather patterns (WWP), westerly perturbations responsible for most of the precipitation falling over the Hindu-Kush Karakoram (HKK) during winter, and the mechanisms responsible for their regulation. WWP originate from the northeastern Atlantic and the Mediterranean, move eastward and often intensify east of about 40°E before they reach the HKK region. Particular attention is given to the analysis of the link between the North Atlantic Oscillation (NAO) and these systems. To this end, we use 1) an ensemble of precipitation datasets, including satellite TRMM observations, three raingauge-based datasets (APHRODITE, CRU and GPCC), the ERA40 reanalyses and the global climate model EC-Earth, 2) evaporation, specific humidity, geopotential and wind data from ERA40 and EC-Earth, 3) a NAO index computed for ERA40 and EC-Earth from sea level pressure data. Our analysis shows that winter precipitation over the HKK exhibits a high interannual variability and above (below) than normal precipitation is found in correspondence of the positive (negative) NAO phase. The Persian Gulf, the northern Arabian Sea and the Red Sea are important moisture sources for winter precipitation in the HKK and enhanced evaporation from these reservoirs occurs during the positive NAO phase. We investigate the association between enhanced evaporation, changes in surface wind intensity and humidity transport towards the HKK. EC-Earth is able to capture the NAO-precipitation signal over the HKK and the mechanisms associated with the WWP described above. Further investigations will include the possibility to repeat the WWP analysis with EC-Earth for the last century (from 1850) and for the future (until 2100) under different emission scenarios, in order to investigate possible changes that occurred and might occur in the WWP activity and the consequences for precipitation in the Karakoram.

The deep structure beneath the Pamir - Hindu Kush region from teleseismic tomography  

NASA Astrophysics Data System (ADS)

The Pamir - Hindu Kush orogenic system is surely one of the least studied corners along the India-Eurasia collisional belt despite featuring several tectonically unique features. The lack of modern geophysical data from the region left the deep processes and structures that cause and host the unique intermediate depth earthquakes here mostly in the dark. To shed light on some of these processes we image the seismic velocity structure in the upper mantle and transition zone. We implemented a tomographic inversion for P-wave velocities based on teleseismic earthquakes recorded at temporal and permanent seismic stations within the study region. Our study is mainly based on the temporary seismic deployments from the TIPAGE (Tien Shan Pamir Geodynamic Project), FERGHANA and TIPTIMON (Tien Shan Pamir Monitoring Program) projects. Within the framework of these projects, 40, 20 and 25 mostly broadband stations were deployed from mid-2008 to mid-2010 and from June 2012 onwards within Tajikistan and Kyrgyzstan. These data were complemented by a similar number of permanent stations covering in the course most of central Asia. We measured so far more than 30,000 phase arrivals from approx. 700 earthquakes occurring at epicentral distances between 20 to 180 degree. This data set is inverted simultaneously for velocity anomalies and station corrections. To account for the large variations of crustal thickness beneath the study region, we implemented a newly determined Moho model for the Pamir and surroundings, which is based on receiver function analysis. The resulting tomographic model extends to depths of approximately 500 km and covers the area between 67 to 79 degree East and 36 to 44 degree North. We will present preliminary P wave velocity images based on the currently available data set.

Debris-flow hazards on tributary junction fans, Chitral, Hindu Kush Range, northern Pakistan  

NASA Astrophysics Data System (ADS)

The Chitral district of northern Pakistan lies in the eastern Hindu Kush Range. The population in this high-relief mountainous terrain is restricted to tributary-junction fans in the Chitral valley. Proximity to steep valley slopes renders these fans prone to hydrogeomorphic hazards, including landslides, floods and debris flows.This paper focuses on debris-flow hazards on tributary-junction fans in Chitral. Using field observations, satellite-image analyses and a preliminary morphometry, the tributary-junction fans in the Chitral valley are classified into (1) discrete and (2) composite. The discrete fans are modern-day active landforms and include debris cones associated with ephemeral gullies, debris fans associated with ephemeral channels and alluvial fans formed by perennial streams. The composite fans are a collage of sediment deposits of widely different ages and formed by diverse alluvial-fan forming processes. These include fans formed predominantly during MIS-2/Holocene interglacial stages superimposed by modern-day alluvial and debris fans. Composite fans are turned into relict fans when entrenched by modern-day perennial streams. These deeply incised channels discharge their sediment load directly into the trunk river without significant spread on fan surface. In comparison, when associated with ephemeral streams, active debris fans develop directly at composite-fan surfaces. Major settlements in Chitral are located on composite fans, as they provide large tracts of leveled land with easy accesses to water from the tributary streams. These fan surfaces are relatively more stable, especially when they are entrenched by perennial streams (e.g., Chitral, Ayun, and Reshun). When associated with ephemeral streams (e.g., Snowghar) or a combination of ephemeral and perennial streams (e.g., Drosh), these fans are subject to frequent debris-flow hazards.Fans associated with ephemeral streams are prone to high-frequency (˜10 years return period) debris-flow hazards. By comparison, fans associated with perennial streams are impacted by debris-flow hazards during exceptionally large events with return periods of ˜30 years. This study has utility for quick debris-flow hazard assessment in high-relief mountainous regions, especially in arid- to semi-arid south-central Asia where hazard zonation maps are generally lacking.

Blood groups, ABH saliva secretion and colour vision deficiency in Hindu castes and religious groups of West Godavari, Andhra Pradesh, India.  

PubMed

The distribution of A1A2B0 and Rh(D) blood groups, ABH saliva secretion and red-green colour blindness among fourteen Hindu caste groups, besides Christian and Muslim populations of West Godavari District, Andhra Pradesh, India, is reported. All the Hindu castes except Brahmin, Kshatriya and Reddy exhibit relatively higher frequency of group B over group A. The subtyping of group A reveals that group A2 records an incidence ranging from 0.98% to 7.78%. The interpopulation chi-square tests for A1A2B0 blood group distribution indicate significant variation between several Hindu castes. The Vysya, Reddy and Adi Andhra castes not only differ from each other but also register significant variation from a majority of other populations. In the ABH saliva secretion also Vysya deviate from all other populations by recording the highest incidence (37.70%) of non-secretors, while the lowest frequency (19.98%) was observed among Kamma. The Rh(D) negative blood group is observed in all Hindu castes and religious groups with an incidence ranging from 1.04% in Vysya to 8.11% in Kamma. All the sixteen populations investigated exhibit prevalence of red-green colour blindness with a relatively higher frequency of deutan type over protan. PMID:7840536

Distribution of seismicity in the Pamir-Tien Shan-Hindu Kush region, central Asia, from TIPAGE seismic data  

NASA Astrophysics Data System (ADS)

The Pamir-Hindu Kush region in central Asia is unique as it hosts vigorous intermediate-depth (80-300 km) seismicity in the continental interior far away from oceanic plate subduction. The earthquakes occur within an S-shaped seismic zone extending from north-western Afghanistan into the Eastern Pamir plateau. This zone shows an intriguing geometry, with earthquake hypocenter locations resembling a Wadati-Benioff zone with significant change in its dip along strike, from sub-vertically northward in the Hindu Kush to shallower southward dipping in the Eastern Pamir. The interpretation of these observations and the nature of the seismic zone are still debated. Proposed models include two-sided subduction of Indian and Asian lithosphere, an overturned slab of exclusively Indian material as well as scenarios involving delamination of mantle lithosphere. Another unsolved question is whether the subducted material is of continental or oceanic nature. Plate reconstructions provide no ocean of fitting age, yet absence of hydrated oceanic lithosphere also takes away the mechanism to generate earthquakes at the pressure and temperature regime of the upper mantle. Analyzing two years of data (2008-2010) from a number of new temporary deployments as well as permanent stations in the region, we detected more than 15,000 earthquakes. The sheer number of events prohibits a manual determination of phase onsets. We therefore implemented an automatic scheme that uses state-of-the-art picking algorithms for both P and S phases including a quality assessment of the phase arrivals. The scheme involves several stages of picking, relocation, re-picking and weeding out spurious arrivals. We will demonstrate the robustness of the scheme by comparison with several hand-picked sub sets of the catalogue. We further refined the earthquake locations by determining differential travel times for clustered events using cross correlation and the double-difference relocation algorithm. Our results reveal some new details about the structure and geometry of the seismic zone: in the Eastern Pamir, intermediate-depth seismicity is confined to depths between 90 and 180 km and thus clearly separated from shallow seismicity along the Main Pamir Thrust, which does not reach depths in excess of 30 km. The lower crust throughout the Pamir appears to be completely aseismic. The gap between crustal and mantle seismicity persists along-strike, but becomes smaller towards the west. The mantle seismic zone appears continuous along its shallowest level (~90-100 km depth) all the way from the Hindu Kush to the eastern Pamir. On this "rack" hang three "curtains" with high seismic activity and increasing steepness and larger maximum depths from east to west.

Participation in Mass Gatherings Can Benefit Well-Being: Longitudinal and Control Data from a North Indian Hindu Pilgrimage Event  

PubMed Central

How does participation in a long-duration mass gathering (such as a pilgrimage event) impact well-being? There are good reasons to believe such collective events pose risks to health. There are risks associated with communicable diseases. Moreover, the physical conditions at such events (noise, crowding, harsh conditions) are often detrimental to well-being. Yet, at the same time, social psychological research suggests participation in group-related activities can impact well-being positively, and we therefore investigated if participating in a long-duration mass gathering can actually bring such benefits. In our research we studied one of the world's largest collective events – a demanding month-long Hindu religious festival in North India. Participants (comprising 416 pilgrims who attended the gathering for the whole month of its duration, and 127 controls who did not) completed measures of self-assessed well-being and symptoms of ill-health at two time points. The first was a month before the gathering commenced, the second was a month after it finished. We found that those participating in this collective event reported a longitudinal increase in well-being relative to those who did not participate. Our data therefore imply we should reconceptualise how mass gatherings impact individuals. Although such gatherings can entail significant health risks, the benefits for well-being also need recognition. Indeed, an exclusive focus on risk is misleading and limits our understanding of why such events may be so attractive. More importantly, as our research is longitudinal and includes a control group, our work adds robust evidence to the social psychological literature concerning the relationship between participation in social group activities and well-being.

Spatial Distribution of the Earthquakes beneath the Pamir-Hindu Kush Region: Implications for the Collision between two Oppositely Subducted Slabs  

NASA Astrophysics Data System (ADS)

We employed a double-difference algorithm (hypoDD) to relocate the Earthquakes reported by the International Seismological Center within the region bounded by 66~78°E and 32~42°N between 1964 and 2003. Among the listed 10224 events in the catalog, 7655 events have at least six P-wave arrival times recorded by 279 stations in the region within 60~90°E and 20~50°N. Totally we have about 135,000 P wave arrival picks and 42,000 S wave arrival picks. 269,365 P-phase pairs and 212,354 S-phase pairs are selected. The average offset between linked events is 10.74 km. The double-difference travel time match in the hypoDD program retains 6018 out of the 7655 events. Then 4751 events are grouped into 182 clusters recorded by 80 stations. The other 1267 events are outliers. Finally 2134 events are successfully relocated and 1479 of them have depth greater than 70 km. There is a distinct feature beneath Hindu Kush region, a double-layered Wadati-Benioff zone which has never been revealed before. Both layers are composed of two parts: the upper part and the lower part. However, the Wadati-Benioff zone in the Pamir region is totally different: it does not have double-layered structure. The Wadati-Benioff zone beneath the Hindu Kush region and the one beneath the Pamir region meet with each other at depth of about 130 km and form back-to-back bow shapes at the boundary region. This explicit feature not only gainsays the statement that a gap exists between the Wadati-Benioff zones beneath the Hindu Kush and the Pamir, but also gainsays the statement that the two Wadati-Benioff zones have geometrical coherence. Based upon above results, along with Harvard CMT solutions, seismological tomography results and geochemical evidences, we propose that beneath the Pamir-Hindu Kush region there exist two oppositely subducted slabs which are colliding with each other at depth of about 130 km. This new model is different from the tear model. It can reasonably explain the Harvard CMT solutions. It naturally relates the intermediate-depth earthquakes under the Pamir with both the intense shallow earthquakes along the northern boundary of the Pamir in Tajikistan and the Ophiolite belt facing south in northern Pamir zone. It also helps us find a way out of the difficulty that Punjab Wedge could not supply enough material diversely subducting into the deep Earth’s interior of Pamir region although it can exert strong extrusion to Pamir zone. When the plate coming from south does not have enough material deeply subducting into the Pamir region, south-concaved northern Pamir arc is indeed the right place for supplying enough material. This new model is also different from the traditional opposing subduction model. It is not based on chanciness. It supplies a reasonable solution to overcome the difficulty that we will face when we find that the seismic gap between the two Wadati-Benioff zones does not exist. When there are no strong evidences for the traditional opposing subduction model, “collision” is the key to reconcile all observations.

The short-form revised Eysenck personality questionnaire: A Hindi edition (EPQRS-H)  

PubMed Central

Background: There is a growing consensus about the validity of human personality traits as important dispositions toward feelings and behaviors (Matthews, Deary, & Whiteman, 2003). Materials and Methods: Here we examine the reliability of the Hindi translation of the Eysenck Personality Questionnaire-Revised Short Form (EPQR-S; Eysenck, Eysenck, & Barrett, 1985), which consists of 48 items that assess neuroticism, extraversion, psychoticism, and lying. The questionnaire was first translated into Hindi and then back translated. Subsequently, it was administered to 202 students (78 men and 124 women) from Banaras Hindu University. The internal consistency of the scale was evaluated. Results: The findings provide satisfactory psychometric properties of the extraversion, neuroticism and lie scales. The psychoticism scale, however, was found to be less satisfactory. Conclusion: It can be proposed that due to satisfactory internal consistency scores, the EPQRS-H is a reliable scale for the measurement of various personality traits.

Variability of GPS derived water vapor and comparison with MODIS data over the Indo-Gangetic plains  

NASA Astrophysics Data System (ADS)

The water vapor is one of the important constituents of the atmosphere that affects the thermodynamics of the atmosphere and has direct impact on the weather conditions. The total column atmospheric water vapor, obtained from Global Positioning System (GPS) and Moderate Resolution Imaging Spectroradiometer (MODIS), is found to be very dynamic over the Indo-Gangetic (IG) plains. In this paper, we present an analysis of GPS data recently deployed (as of May 2007) on the campus of Banaras Hindu University, Varanasi (latitude 25°15?N, longitude 82°59?E). Further, we have compared the variability of water vapor from Kanpur GPS, AERONET and MODIS water vapor data for the year 2007. The monthly variability of water vapor shows characteristic features and dynamics of water vapor between two closely spaced GPS stations, found to be controlled by monsoon dynamics and wind pattern.

Detection of the timing and duration of snowmelt in the Hindu Kush-Himalaya using QuikSCAT, 2000-2008  

NASA Astrophysics Data System (ADS)

The Hindu Kush-Himalayan (HKH) region holds the largest mass of ice in Central Asia and is highly vulnerable to global climate change, experiencing significant warming (0.21 ± 0.08 °C/decade) over the past few decades. Accurate monitoring of the timing and duration of snowmelt across the HKH region is important, as this region is expected to experience further warming in response to increased greenhouse gas forcing. Despite the many advantages and applications of satellite-derived radar scatterometer data shown for capturing ice and snow melt dynamics at high latitudes, similar comprehensive freeze/thaw detection studies at lower latitudes (including the HKH region) are still absent from the scientific literature. A comprehensive freeze/thaw detection study is utilized on perennial snow/ice and seasonal snow cover for the first time in the Himalayan and Karakoram regions. A dynamic threshold-based method is applied to enhanced QuikSCAT Ku-band backscatter observations from 2000 to 2008 that (a) provides spatial maps of the timing of melt, freeze, and melt season duration, and (b) emphasizes regional variability in freeze/thaw dynamics. The resulting average melt durations for 2000-2008 are 161 ± 11 days (early May-mid-October) for the eastern Himalayas, 130 ± 16 days (late May-early October) for the central Himalayas, 124 ± 13 days (mid-May-mid-September) for the western Himalayas, and 124 ± 12 days (late May-late September) for the Karakoram region. The eastern Himalayan region has on average an earlier melt onset, a later freeze-up, and therefore a longer melt season (~5 weeks) relative to the central and western Himalayan and the Karakoram regions. Snowmelt dynamics exhibit regional and interannual variability with clear connections to terrain features, in particular elevation and aspect. With respect to ongoing controversies surrounding melt in the Himalayan region, this study provides an overall perspective of regional differences in melt onset, freeze-up, and melt duration that have important implications for glaciological and hydrological processes across the HKH region.

Universal Usability  

NASA Astrophysics Data System (ADS)

Universal usability of World Wide Web (Web) environments—that is, having 90% of households as successful users—requires universal access, usability, and universal design. Factors such as Web technology and user-centered design contribute to universal access and usability, but key to universal usability is a universal design methodology. Universal design principles for the Web follow from universal design principles for the built environment, and emphasize perceptibility, self-explanation, and tailorability for the user. Universally usable Web environments offer the benefit of expanded participation, as well as the unanticipated benefits that generally follow from innovative design initiatives. However, to achieve Web universal usability, Web designers need tools that facilitate the design of intuitive interfaces without sacrificing universal access.

Our Universe  

NASA Astrophysics Data System (ADS)

The Universe in which we live is unimaginably vast and ancient, with countless star systems, galaxies, and extraordinary phenomena such as black holes, dark matter, and gamma ray bursts. What phenomena remain mysteries, even to seasoned scientists? Our Universe is a fascinating collection of essays by some of the world's foremost astrophysicists. Some are theorists, some computational modelers, some observers, but all offer their insights into the most cutting-edge, difficult, and curious aspects of astrophysics. Compiled, the essays describe more than the latest techniques and findings. Each of the ten contributors offers a more personal perspective on their work, revealing what motivates them and how their careers and lives have been shaped by their desire to understand our universe. S. Alan Stern is Director of the Department of Space Studies at Southwest Research Institute in Boulder, Colorado. He is a planetary scientist and astrophysicist with both observational and theoretical interests. Stern is an avid pilot and a principal investigator in NASA's planetary research program, and he was selected to be a NASA space shuttle mission specialist finalist. He is the author of more than 100 papers and popular articles. His most recent book is Pluto & Charon (Wiley, 1997).

If the equation of state for ''dark energy'' varies periodically, the expansion of the Universe may have undergone alternating eras of acceleration and deceleration. We examine a specific form that survives existing observational tests, does not single out the present state of the Universe as exceptional, and suggests a future much like the matter-dominated past: a smooth expansion without a final inflationary epoch.

Hemostasis research in India: past, present, and future.  

PubMed

Hemostasis research in India has a long history considering the fact that it is one of the youngest specialities in the world. If we take creation of prothrombin time (PT) test as one of the beginning of modern hemostsis research, then the specialty is no older than 60 years. School of Tropical Medicine Kolkata, Banaras Hindu University, All India Institute of Medical Sciences at Delhi, Christian Medical College at Vellore, Post Graduate Institute of Medical Education and Research at Chandigarh, and KEM Hospital at Mumbai contributed substantially in defining various bleeding disorders in our country. Unfortunately, some of these institutes are no longer as active in the field as they used to be. Currently, the Institute of Immunohaematology at Mumbai, Chrstian medical College at Vellore, and All India Institute of Medical Sciences at Delhi are actively engaged in hemostsis research in India. Developing prenatal diagnostic technologies, mutation detection of various hemostatic disorders, developing low-cost management technologies for hemophilia, and other bleeding disorders are becoming important present day research activity in the area of hemostasis in addition to age old areas of prevalence and unusual case description studies. Entry of many new corporate hospitals, development of structured postgraduate training program in hematology, and easy availability of instruments and reagents are likely to foster further growth in this area of medical research in India in future.

Diarrhea, CD4 counts and enteric infections in a hospital - based cohort of HIV-infected patients around Varanasi, India  

PubMed Central

Background As most of the studies in HIV patients with diarrhea were cross sectional, focusing on the etiological agents, we are reporting data on the rate of diarrhea, associations between diarrhea and CD4 counts and variation in frequency of identifying a pathogen with consistency of diarrhea and duration in a prospective hospital based study. Methods Stool specimens were obtained between Jan 2001 and April 2003 from HIV infected adults with diarrhea presenting to Infectious Disease clinic, Banaras Hindu University, Varanasi. In all patients with diarrhea, specimens were examined by microscopy and cultures to identify pathogens. Results During the study, 630 person years of observations with diarrhea were analyzed. 140 stool samples were collected representing 43% of episodes of reported diarrhea. Positivity of finding a pathogen from watery stools and formed stools were 40%&24% respectively (p < 0.01) probably due to associated inflammation is more in watery diarrhea. Patients having chronic diarrhea are 2.25 (95%CI 1.52–2.81) times at more risk of developing other opportunistic infections compared to those who don't have. However this is not true with the acute diarrhea where risk of harboring the opportunistic infections remain same. Conclusion Diarrhea was most strongly associated with low CD4 counts. Over two-thirds of diarrheal episodes were undiagnosed, suggesting that unidentified agents or primary HIV enteropathy are important causes of diarrhea in this population. There is a strong negative association between duration of diarrhea and CD4 levels

Effect of dust load on the leaf attributes of the tree species growing along the roadside.  

PubMed

Dust is considered as one of the most widespread air pollutants. The objective of the study was to analyse the effect of dust load (DL) on the leaf attributes of the four tree species planted along the roadside at a low pollution Banaras Hindu University (BHU) campus and a highly polluted industrial area (Chunar, Mirzapur) of India. The studied leaf attributes were: leaf area, specific leaf area (SLA), relative water content (RWC), leaf nitrogen content (LNC), leaf phosphorus content (LPC), chlorophyll content (Chl), maximum stomatal conductance (Gs(max)), maximum photosynthetic rate (A (max)) and intrinsic water-use efficiency (WUEi). Results showed significant effect of sites and species for DL and the leaf attributes. Average DL across the four tree species was greater at Chunar, whereas, the average values of leaf attributes were greater at the BHU campus. Maximum DL was observed for Tectona grandis at Chunar site and minimum for Syzygium cumini at BHU campus. Across the two sites, maximum value of SLA, Chl and Gs(max) were exhibited by S. cumini, whereas, the greatest value of RWC, LNC, LPC, A (max) and WUEi were observed in Anthocephalus cadamba. A. cadamba and S. cumini exhibited 28 and 27 times more dust accumulation, respectively, at the most polluted Chunar site as compared to the BHU campus. They also exhibited less reduction in A (max) due to dust deposition as compared to the other two species. Therefore, both these species may be promoted for plantation along the roadside of the sites having greater dust deposition. PMID:22367367

Universe: The Universe Beyond our Solar System  

NSDL National Science Digital Library

This Science Object is the fourth of five Science Objects in the Universe SciPack. It explores the more unknown parts of the universe beyond our solar system and provides an understanding of where and how we fit into the universe as a whole. Astronomers have carefully measured the changing positions of stars, leading them to believe that the Sun is located about half-way out from the center of a disk-shaped galaxy of stars, part of which can be seen as a glowing band of light that spans the sky on a very clear night. Although our Sun is a single star, most stars exist in systems of two or more stars orbiting around one another and are arranged in huge star clusters. Galaxies are isolated collections of billions of gravitationally bound stars and immense clouds of gas and dust. Galaxies are, in turn, grouped into galaxy clusters and super-clusters. The universe contains many billions of galaxies separated by immense distances of mostly empty space. Some of these distant galaxies are so far away that their light takes several billion years to reach Earth. This means that here on Earth we are seeing them as they were that long ago. Learning Outcomes:� Arrange various objects in order of size and distance, ranging from space probes and moons to galaxies and galactic clusters.� Catalogue, in simple terms, the objects within a galaxy.� Generally explain "what is within what" (planetary systems, star clusters, galaxies, etc.).� Describe the location of our solar system within the Milky Way galaxy.� Describe the limitations of using parallax, radar, and brightness to measure the distance of objects from Earth, and classify objects whose distance from Earth could be accurately measured using each type of measurement strategy.

The Universe is a bewildering place to the uninitiated. The concepts and theories that govern space seem complex and often contradictory. The Universe Revealed provides the keys to unlocking the wonders of the cosmos. Elegantly written and lavishly illustrated, it begins with the Sun and stretches through our solar system into deepest space. Lucid prose, written by many of the people who have shaped our current thinking on space, and spectacular photographs make the physics of the Universe accessible and provide a solid background for understanding the most recent astronomical discoveries. Covering the most intriguing features of the cosmos, the topics discussed range from the Earth and global warming to cosmic collisions and the size of the Universe. Major sections examine the Solar System, stars, galaxies, cosmology, and the observational techniques used by astronomers, both amateur and professional. The Universe Revealed represents the collaboration of internationally renowned experts in astronomy and cosmology, with contributions from authors including David Malin, F. Duccio Macchetto, Iain Nicholson, Neil Bone, Ian Ridpath, Seth Shostak, Mike Lancaster, Steve Miller, Ken Croswell, Geoff McNamara, and Steven Young.

IS THE UNIVERSE ROTATING?  

SciTech Connect

Models of a rotating universe have been studied widely since the work of Goedel, who showed an example that is consistent with general relativity. By now, the possibility of a rotating universe has been discussed comprehensively in the framework of some types of Bianchi's models, such as Type V, VII, and IX and different approaches have been proposed to constrain the rotation. Recent discoveries of some non-Gaussian properties of the Cosmic Microwave Background Anisotropies (CMBA), such as the suppression of the quadrupole and the alignment of some multipoles draw attention to some Bianchi models with rotation. However, cosmological data, such as those of the CMBA, strongly prefer a homogeneous and isotropic model. Therefore, it is of interest to discuss the rotation of the universe as a perturbation of the Robertson-Walker metric, to constrain the rotating speed by cosmological data and to discuss whether it could be the origin of the non-Gaussian properties of the CMBA mentioned above. Here, we derive the general form of the metric (up to second-order perturbations) which is compatible with the rotation perturbation in a flat LAMBDA-CDM universe. By comparing the second-order Sachs-Wolfe effect due to rotation with the CMBA data, we constrain the angular speed of the rotation to be less than 10{sup -9} rad yr{sup -1} at the last scattering surface. This provides the first constraint on the shear-free rotation of a LAMBDACDM universe.

Physics at Fisk University  

NASA Astrophysics Data System (ADS)

Fisk University was started in 1866 for predominantly Black students at the end of the Civil War. Its Department of Physics was started in 1931, under the chairmanship of Dr. Elmer Imes, Fisk '03, a research physicist in the field of infrared spectroscopy. Imes set the stage for Fisk's development of an infrared spectroscopy research laboratory. After Imes' untimely death in 1942, one of his early physics majors, James Lawson, chaired the Fisk Physics Department and soon obtained a research type infrared instrument from the University of Michigan. By the early 50's, five Fisk graduate students in physics published with their faculty mentors, the results of their M.A. degree research in infrared spectroscopy and read papers at the meetings of SESAPS. This active participation in SESAPS of Fisk's Black physicists was the impetus which caused SESAPS in 1954 to switch its meetings from segregated to unsegregated facilities. SESAPS then accepted the invitation of Fisk University to hold its 1955 annual meeting on the Fisk campus. But there is lots more to tell of Physics at Fisk University: research in ion optics and the solid state (like growing crystals in ``zero gravity"); research collaboration with Oak Ridge, Vanderbilt and Bordeaux, France; diversification of the physics student population; the impact of Fisk's physicists on the University's financial ``ups and downs"; etc. We will touch on all this and more!

The Biological Universe  

NASA Astrophysics Data System (ADS)

Throughout the twentieth century, from the furor over Percival Lowell's claim of canals on Mars to the sophisticated Search for Extraterrestrial Intelligence, otherworldly life has often intrigued and occasionally consumed science and the public. The Biological Universe provides a rich and colorful history of the attempts during the twentieth century to answer questions such as whether "biological law" reigns throughout the universe and whether there are other histories, religions, and philosophies outside those on Earth. Covering a broad range of topics, including the search for life in the solar system, the origins of life, UFOs, and aliens in science fiction, Steven J. Dick shows how the concept of extraterrestrial intelligence is a world view of its own, a "biophysical cosmology" that seeks confirmation no less than physical views of the universe. This book will fascinate astronomers, historians of science, biochemists, and science fiction readers.

Baby universe theory.  

NASA Astrophysics Data System (ADS)

The authors give an elementary review of the so called "the theory of baby universes" which is a series of ideas or speculations about some effects in quantum gravity, viz. the effect of a certain type of wormholes, representing the exchange of small 3-space universes called baby universes. They consider this "theory" as being physically and scientifically a very promising candidate for a theory of everything. It is, however, mathematically lacking any strong foundation at all. It solves several fine-tuning problems: First of all the cosmological constant problem, and also the strong CP-problem and the hierarchy problem. The authors also speculate that it might predict the possibility of influencing the probability distributions of the outcome of quantum mechanical measurements at one time by acts at a later time.

The Classification of Universes  

ScienceCinema

We define a universe as the contents of a spacetime box with comoving walls, large enough to contain measurable phenomena, but not much larger. This allows the construction of a local ensemble of such universes, given modest extrapolations of the observed properties of the cosmos. We then assume that further out similar universes can be constructed, but with different standard model parameters, strongly correlated with the size in a definite way, where by size is meant the Hubble scale at late times. This allows an estimate of the range of sizes supporting life as we know it. The result allows some understanding of the hierarchy problems of particle physics. Other possible implications of the assumptions made will be discussed, including a possible connection between the QCD vacuum structure and cosmological horizon structure. In all cases, our approach is as bottoms-up and as phenomenological as possible, suggesting that theories of the multiverse may eventually lay some claim of being scientific.

Here we develop a self-consistent theory of dynamical perturbations in complex systems, allowing us to systematically separate the contribution of the network topology and dynamics. The formalism covers a broad range of steady-state dynamical processes and offers testable predictions regarding the system's response to perturbations and the development of correlations. It predicts several distinct universality classes whose characteristics can be derived directly from the continuum equation governing the system's dynamics and which are validated on several canonical network-based dynamical systems, from biochemical dynamics to epidemic spreading. Finally, we collect experimental data pertaining to social and biological systems, demonstrating that we can accurately uncover their universality class even in the absence of an appropriate continuum theory that governs the system's dynamics.

Universality of geometry  

NASA Astrophysics Data System (ADS)

In models of emergent gravity the metric arises as the expectation value of some collective field. Usually, many different collective fields with appropriate tensor properties are candidates for a metric. Which collective field describes the "physical geometry"? We resolve this "metric ambiguity" by an investigation of the most general form of the quantum effective action for several metrics. In the long-distance limit the physical metric is universal and accounts for a massless graviton. Other degrees of freedom contained in the various metric candidates describe very massive scalars and symmetric second rank tensors. They only play a role at microscopic distances, typically around the Planck length. The universality of geometry at long distances extends to the vierbein and the connection. On the other hand, for distances and time intervals of Planck size geometry looses its universal meaning. Time is born with the big bang.

Visiting the Gödel universe.  

PubMed

Visualization of general relativity illustrates aspects of Einstein's insights into the curved nature of space and time to the expert as well as the layperson. One of the most interesting models which came up with Einstein's theory was developed by Kurt Gödel in 1949. The Gödel universe is a valid solution of Einstein's field equations, making it a possible physical description of our universe. It offers remarkable features like the existence of an optical horizon beyond which time travel is possible. Although we know that our universe is not a Gödel universe, it is interesting to visualize physical aspects of a world model resulting from a theory which is highly confirmed in scientific history. Standard techniques to adopt an egocentric point of view in a relativistic world model have shortcomings with respect to the time needed to render an image as well as difficulties in applying a direct illumination model. In this paper we want to face both issues to reduce the gap between common visualization standards and relativistic visualization. We will introduce two techniques to speed up recalculation of images by means of preprocessing and lookup tables and to increase image quality through a special optimization applicable to the Gödel universe. The first technique allows the physicist to understand the different effects of general relativity faster and better by generating images from existing datasets interactively. By using the intrinsic symmetries of Gödel's spacetime which are expressed by the Killing vector field, we are able to reduce the necessary calculations to simple cases using the second technique. This even makes it feasible to account for a direct illumination model during the rendering process. Although the presented methods are applied to Gödel's universe, they can also be extended to other manifolds, for example light propagation in moving dielectric media. Therefore, other areas of research can benefit from these generic improvements. PMID:18989011

Birth of inflationary universes  

SciTech Connect

A cosmological model is proposed in which the Universe is created by quantum tunneling from ''nothing'' into a de Sitter space. The tunneling is described by a de Sitter-- p Hawking--Moss instanton. After the tunneling, the model evolves along the lines of the inflationary scenario. It is argued that at any time there exist parts of the Universe which are still in the de Sitter phase, while other parts have already recollapsed. This model does not have a big-bang singularity and does not require any initial or boundary conditions.

The images reveal the structure that existed when the universe was a tiny fraction of its current age and 1,000 times smaller and hotter than it is today. Research carried out as part of this project is shedding light on some of cosmology's long-standing mysteries, such as the nature of the matter and energy that dominate intergalactic space and whether space is ''curved'' or ''flat.''(c) 2000 Optical Society of America.

Anisotropically inflating universes  

SciTech Connect

We show that in theories of gravity that add quadratic curvature invariants to the Einstein-Hilbert action there exist expanding vacuum cosmologies with positive cosmological constant which do not approach the de Sitter universe. Exact solutions are found which inflate anisotropically. This behavior is driven by the Ricci curvature invariant and has no counterpart in the general-relativistic limit. These examples show that the cosmic no-hair theorem does not hold in these higher-order extensions of general relativity and raises new questions about the ubiquity of inflation in the very early universe and the thermodynamics of gravitational fields.

There are solutions of Israel junction conditions that describe the detachment of a region of spacetime, a bubble, from what can be called the parent spacetime. In the past these solutions have been mostly considered in the context of inflationary cosmology (the so called baby universes). We will i) briefly review these ideas, ii) show that they can be of interest under more general settings and iii) present solutions where it is possible to create a universe at arbitrarily small energy cost. This could have interesting applications for quantum gravity and particle physics, besides cosmology.

Evolution of the Universe  

NASA Astrophysics Data System (ADS)

Cosmology is in the midst of a scientific revolution that is establishing its lasting foundations. The good agreement between many different sorts of observations and the predictions of the now-standard Lambda Cold Dark Matter (LCDM) theory gives us hope that this is humanity's first picture of the history of the universe as a whole that might actually be true. An unexpected feature of this new picture is that we humans appear to be central or special in many ways -- for example, we are made of the rarest stuff in the universe (stardust); we are intermediate in size between the smallest possible size (the Planck length) and the largest size (the cosmic horizon); and we are living at a pivotal time: the period in the history of the universe when its expansion began to accelerate rather than slow down, and in the middle of the ten-billion-year lifetime of our solar system and of the billion year most habitable period of our planet, and at what must be the end of the exponential growth of human impact on the earth. This talk will review key observations that support modern cosmology, describe some symbolic ways of understanding the modern cosmos, and discuss some possible implications of a cosmic perspective for our 21st century worldview. Based on a new book, The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos, by Joel R. Primack and Nancy Ellen Abrams (Riverhead Books, April 2006).

Universal Test Facility  

NASA Astrophysics Data System (ADS)

A universal test facility (UTF) for Space Station Freedom is developed. In this context, universal means that the experimental rack design must be: automated, highly marketable, and able to perform diverse microgravity experiments according to NASA space station requirements. In order to fulfill these broad objectives, the facility's customers, and their respective requirements, are first defined. From these definitions, specific design goals and the scope of the first phase of this project are determined. An examination is first made into what types of research are most likely to make the UTF marketable. Based on our findings, the experiments for which the UTF would most likely be used included: protein crystal growth, hydroponics food growth, gas combustion, gallium arsenide crystal growth, microorganism development, and cell encapsulation. Therefore, the UTF is designed to fulfill all of the major requirements for the experiments listed above. The versatility of the design is achieved by taking advantage of the many overlapping requirements presented by these experiments.

Universal newborn hearing screening  

PubMed Central

The present statement reviews the evidence for universal newborn hearing screening (UNHS). A systematic review of the literature was conducted using Medline and using search dates from 1996 to the third week of August 2009. The following search terms were used: neonatal screening AND hearing loss AND hearing disorders. The key phrase “universal newborn hearing screening” was also searched. The Cochrane Central Register of Controlled Trials and systematic reviews was searched. Three systematic reviews, one controlled non-randomized trial and multiple cohort studies were found. It was determined that there was satisfactory evidence to support UNHS. The results of the available literature are consistent and indicate clear evidence that without UNHS, delayed diagnosis leads to significant harm for children and their families; with UNHS, diagnosis and intervention occur earlier; earlier intervention translates to improved language outcomes; and in well-run programs, there is negligible harm from screening.

The quintessential universe  

NASA Astrophysics Data System (ADS)

Recent evidence suggests that most of the energy in the universe consists of some form of dark energy that is gravitationally self-repulsive and that is causing the expansion rate of the universe to accelerate. We review the evidence, including recent measurements of the cosmic microwave background by the DASI, BOOMerang and MAXIMA groups. The dark energy may consist of vacuum energy density (or, equivalently, a cosmological constant), or quintessence, a time-evolving, spatially inhomogeneous component with negative pressure. A key problem is to explain the initial conditions required to have the energy density nearly coincident with the matter density today. A possible solution is ``k-essence,'' a form of quintessence with an attractor-like solution which leads to cosmic acceleration today for a very wide range of initial conditions without fine-tuning and without invoking an anthropic argument. .

Universality in oscillating flows.  

PubMed

We show that oscillating flow of a simple fluid in both the Newtonian and the non-Newtonian regime can be described by a universal function of a single dimensionless scaling parameter omega tau, where omega is the oscillation (angular) frequency and tau is the fluid relaxation time; geometry and linear dimension bear no effect on the flow. Energy dissipation of mechanical resonators in a rarefied gas follows this universality closely in a broad linear dimension (10(-6) m < L < 10(-2) m) and frequency (10(5) Hz < omega/2pi < 10(8) Hz) range. Our results suggest a deep connection between flows of simple and complex fluids. PMID:19437646

Beyond universal precautions.  

PubMed Central

Universal precautions have gained wide acceptance in the literature and are promoted by major health care regulatory bodies as a measure to prevent nosocomial transmission of bloodborne diseases. Nevertheless, Dr. James G. Wright and associates (see pages 1089 to 1095 of this issue) provide evidence of the infrequent use of universal precautions by surgeons in Toronto. Their findings are consistent with those of similar studies and point to the limitations of any safety approach that relies on the active compliance of individuals rather than on passive, environmental controls. Successful approaches to optimizing workplace safety should first emphasize passive measures for risk abatement, including firm policies, the use of safer equipment and techniques, procedural safeguards and regular monitoring. Routine voluntary screening of patients undergoing procedures that pose a high risk of contamination may improve compliance to safety procedures by health care personnel. Further study is required.

The radioactive universe.  

SciTech Connect

In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosmology, depends crucially on the ratio between the energy densities stored in the radion and in the inflaton at the time of inflation. We discuss the general difficulties in reconciling models with low compactification scale (i.e., TeV scale) with the simple picture of inflation.

Universal Indicator Rainbow Trout  

NSDL National Science Digital Library

In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases. The initial coat of indicator changes the color of the paper (it will turn a salmon color if the paper is acidic, and green if it is considered acid-free). From there, adding acids (such as lemon juice) and bases (such as laundry detergent) will further change the color. Universal indicator responds to a wide range of acids and bases, so other home chemicals (shampoo, vinegar, etc.) could be tried to create different colors. For older learners, a paper pattern other than a "rainbow trout" (such as a rainforest bird or other colorful animal) can be used.

Universal quantum interfaces  

SciTech Connect

To observe or control a quantum system, one must interact with it via an interface. This article exhibits simple universal quantum interfaces--quantum input/output ports consisting of a single two-state system or quantum bit that interacts with the system to be observed or controlled. It is shown that under very general conditions the ability to observe and control the quantum bit on its own implies the ability to observe and control the system itself. The interface can also be used as a quantum communication channel, and multiple quantum systems can be connected by interfaces to become an efficient universal quantum computer. Experimental realizations are proposed, and implications for controllability, observability, and quantum information processing are explored.

The spacetimes corresponding to a weak version of the cosmological principle are considered. It appears that, starting from very different criteria, they were already obtained by Stephani and studied by Krasinski and Barnes. The only barotropic universes of this class are the Friedmann-Robertson-Walker ones. Among the others, some admit a general thermodynamic scheme; it is shown that, as for barotropic fluids, such a scheme also imposes additional symmetries.

The Molecular Universe  

NASA Astrophysics Data System (ADS)

During the last decade it has become more and more clear that the molecular universe is widespread and very diverse. The near and mid IR spectra of the diffuse interstellar medium of the Milky Way and other galaxies is dominated by the vibrational emission of large (50 C-atoms) Polycyclic Aromatic Hydrocarbon molecules. These emission features are also bright in many regions of massive star formation as well as in the ashes expelled by stars in their death throes. These ubiquitous molecules lock up about 1-10 % of all the available elemental carbon. It is now also clear that the Diffuse Interstellar Bands in the visible spectral range - which have presented a spectroscopic enigma since their discovery 75 years ago - are due to electronic transitions of interstellar molecules. Besides these PAHs, likely candidates include acetylenic C-chains and fullerenes. Similarly, spectroscopic studies of the rotational, millimeter and submillimeter spectra of molecular clouds - the birthsites of new stars - have revealed a rich inventory of molecules which increases at a pace of about 5 new molecules a year for the last 25 years. Molecules have now been discovered as far back as z = 4.7 when the first burst of star formation accompanied galaxy formation in the universe. Indeed, cooling by molecules probably played as key a role in star formation at that time as it does in the present universe. In the solar system, the chemical composition of comets still attests to its heritage of the interstellar cloud from which the solar system formed 4.5 billion years ago, while carbonaceous meteorites display a very diverse pattern of organic species including a wide variety of amino acids many of which are unknown in nature on Earth. This talk will review the richness of the molecular universe and the processes that play a role in the origin and evolution of these species.

A closed microuniverse that inflates into a macrouniverse loses its particle horizon. The conditions for this rule to apply are discussed.

Such a closed universe may display in vestigial form on the scale of superclusters the polytopal structure of the original microuniverse.

Inflation in the universe  

SciTech Connect

The hot big bang cosmology, or the standard cosmology as it is appropriately known, is a highly successful model, providing a reliable and tested accounting of the Universe from 0.01 sec after the bang until today, some 15 Gyr later. However, very special initial data seem to be required in order to account for the observed smoothness and flatness of our Hubble volume and for the existence of the small primeval density inhomogeneities required for the formation of structure in the Universe. Inflation offers a means of accounting for these special initial data, which is based upon physics at sub-planck energy scales (<< m/sub pl/ approx. = 10/sup 19/ GeV) and is motivated by contemporary ideas in particle theory. Here I review the status of the 'Inflationary Paradigm'. At present essentially all inflationary models involve a very weakly-coupled (quantified by the presence of a dimensionless parameter of order 10/sup -12/ or so) scalar field which is displaced from the minimum of its potential. Regions of the Universe where the scalar field is initially displaced from its minimum undergo inflation as the scalar field relaxes, resulting in a Universe today which resembles ours in regions much larger than our present Hubble volume (approx. = 10/sup 28/ cm), but which on very large scales (>> 10/sup 28/ cm) may be highly irregular. The most conspicuous blemish on the paradigm is the lack of a compelling particle physics model to implement it. I also review some other unresolved issues, and discuss in detail the all important confrontation between inflation and observational data. Finally, I discuss the possibility that inflation leads to large-scale, primeval magnetic fields of sufficient strength to be of astrophysical interest. 123 refs., 4 figs.

[Universal electrogustometer EG-2].  

PubMed

Electrogustometry is a method for taste diagnosis and measurement. The EG-2 project is being developed in cooperation between Warsaw University of Technology and Military institute of Medicine in Warsaw. The device is an evolution of the recent universal electrogustometer EG-1 prototype. Due to considerations and experiences acquired during prototype usage, many enhancements have been incorporated into device. The aim was to create an easy-to-use, portable, battery powered device, enabled for fast measurements. Developed electrogustometer is using innovative, low-power microprocessor system, which control whole device. User interface is based on 5.7" graphical LCD (Liquid Crystal Display) and touchscreen. It can be directly operated by finger or with optional stylus. Dedicated GUI (Graphical User Interface) offers simple, predefined measurements and advance settings of signal parameters. It is also possible to store measurements results and patients data in an internal memory. User interface is multilanguage. Signals for patients examinations, supplied with bipolar electrode, are generated by an on-board circuit using DDS (Direct-Digital Synthesis) and DAC (Digital-to-Analog Converter). Electrogustometer is able to generate DC, sinus, triangle or rectangle signals with current amplitude from 0 to 500 pA and frequency form 0 to 500 Hz. Device is designed for manual and automeasurement modes. By using USB (Universal Serial Bus) port it is possible to retrieve data stored in internal memory and charging of built-in Li-lon battery as a source of power. PMID:21735666

Universally coupled massive gravity  

NASA Astrophysics Data System (ADS)

We derive Einstein’s equations from a linear theory in flat space-time using free-field gauge invariance and universal coupling. The gravitational potential can be either covariant or contravariant and of almost any density weight. We adapt these results to yield universally coupled massive variants of Einstein’s equations, yielding two one-parameter families of distinct theories with spin 2 and spin 0. The Freund-Maheshwari-Schonberg theory is therefore not the unique universally coupled massive generalization of Einstein’s theory, although it is privileged in some respects. The theories we derive are a subset of those found by Ogievetsky and Polubarinov by other means. The question of positive energy, which continues to be discussed, might be addressed numerically in spherical symmetry. We briefly comment on the issue of causality with two observable metrics and the need for gauge freedom and address some criticisms by Padmanabhan of field derivations of Einstein-like equations along the way.

Manual for Afterschool Universe  

NSDL National Science Digital Library

This astronomy program is designed for middle school children in out-of-school-time settings. The program explores basic astronomy concepts (like invisible light, telescopes) and focuses on the universe outside the solar system (stars, galaxies, black holes). By offering programming on these topics outside of the classroom, where schedules are less constrained, Afterschool Universe engages students in science and keeps them interested. Afterschool Universe consists of 12 sessions, each typically requiring 45-60 minutes for implementation. The program is flexibly structured for use in a variety of settings, including astronomy days, summer camps, or year-long afterschool programming. Although sessions build concepts when attended sequentially, each session is intended to be freestanding as not all participants may attend every session. A comprehensive manual provides background information and detailed descriptions of how to conduct each activity. The manual has been written for leaders with little science background. A companion Wweb siteWeb site provides additional information and resources for the program leader. All the activities are done âin the real worldâ and do not require a computer. Suggestions for optional web-based activities are provided for locations with computers or for at-home extensions.

The Universal Ancestor  

NASA Astrophysics Data System (ADS)

A genetic annealing model for the universal ancestor of all extant life is presented; the name of the model derives from its resemblance to physical annealing. The scenario pictured starts when ``genetic temperatures'' were very high, cellular entities (progenotes) were very simple, and information processing systems were inaccurate. Initially, both mutation rate and lateral gene transfer levels were elevated. The latter was pandemic and pervasive to the extent that it, not vertical inheritance, defined the evolutionary dynamic. As increasingly complex and precise biological structures and processes evolved, both the mutation rate and the scope and level of lateral gene transfer, i.e., evolutionary temperature, dropped, and the evolutionary dynamic gradually became that characteristic of modern cells. The various subsystems of the cell ``crystallized,'' i.e., became refractory to lateral gene transfer, at different stages of ``cooling,'' with the translation apparatus probably crystallizing first. Organismal lineages, and so organisms as we know them, did not exist at these early stages. The universal phylogenetic tree, therefore, is not an organismal tree at its base but gradually becomes one as its peripheral branchings emerge. The universal ancestor is not a discrete entity. It is, rather, a diverse community of cells that survives and evolves as a biological unit. This communal ancestor has a physical history but not a genealogical one. Over time, this ancestor refined into a smaller number of increasingly complex cell types with the ancestors of the three primary groupings of organisms arising as a result.

Universe: The Origin and Evolution of the Universe  

NSDL National Science Digital Library

This Science Object is the fifth of five Science Objects in the Universe SciPack. It provides understanding of how the universe formed, how it has changed over time, and how it continues to change today. The 'big bang' theory of universe formation is supported by recent observations of the motion of galaxies, as well as observations of the energy left over from the formation of the universe. This evidence suggests that the origin of the universe occurred approximately 13.6 billion years ago, during a point in time when the state of the universe was much hotter and more dense. The fact that light seen from almost all distant galaxies has longer wavelengths than comparable light here on earth provides evidence that the whole universe has been expanding ever since the big bang (and continues to expand today). Learning Outcomes:� Provide a basic description of the conditions at the beginning of the universe.� Give the approximate age of the universe.� Recognize the scientific account of the current state of the universe given different explanations.� Explain the evidence for an expanding universe.� Describe, in simple terms, how scientists use observations of position and motion to learn about objects in the universe.

Universality of weak selection  

NASA Astrophysics Data System (ADS)

Weak selection, which means a phenotype is slightly advantageous over another, is an important limiting case in evolutionary biology. Recently, it has been introduced into evolutionary game theory. In evolutionary game dynamics, the probability to be imitated or to reproduce depends on the performance in a game. The influence of the game on the stochastic dynamics in finite populations is governed by the intensity of selection. In many models of both unstructured and structured populations, a key assumption allowing analytical calculations is weak selection, which means that all individuals perform approximately equally well. In the weak selection limit many different microscopic evolutionary models have the same or similar properties. How universal is weak selection for those microscopic evolutionary processes? We answer this question by investigating the fixation probability and the average fixation time not only up to linear but also up to higher orders in selection intensity. We find universal higher order expansions, which allow a rescaling of the selection intensity. With this, we can identify specific models which violate (linear) weak selection results, such as the one-third rule of coordination games in finite but large populations.

Open universe from inflation  

SciTech Connect

We present a natural scenario for obtaining an open universe ({Omega}{sub 0}{lt}1) through inflation. In this scenario, there are two epochs of inflationary expansion---an epoch of ``old inflation,`` during which the inflaton field is stuck in a false vacuum, followed by an epoch of ``new inflation,`` during which the inflation field slowly rolls toward its true minimum. During the first epoch, inflation solves the smoothness and horizon problems. Then an open universe (with negative spatial curvature) is created by the nucleation of a single bubble. In effect {Omega} is instantaneously ``reset`` to zero. During the subsequent ``new`` inflation {Omega} rises toward unity. The value of {Omega} today is calculable in terms of the parameters of the potential, and we show that obtaining values significantly different from zero or unity (though within the range 0{lt}{Omega}{lt}1) does not require significant fine-tuning. We compute the spectrum of density perturbations by evolving the Bunch-Davies vacuum modes across the bubble wall into its interior.

Universality in Bacterial Colonies  

NASA Astrophysics Data System (ADS)

The emergent spatial patterns generated by growing bacterial colonies have been the focus of intense study in physics during the last twenty years. Both experimental and theoretical investigations have made possible a clear qualitative picture of the different structures that such colonies can exhibit, depending on the medium on which they are growing. However, there are relatively few quantitative descriptions of these patterns. In this paper, we use a mechanistically detailed simulation framework to measure the scaling exponents associated with the advancing fronts of bacterial colonies on hard agar substrata, aiming to discern the universality class to which the system belongs. We show that the universal behavior exhibited by the colonies can be much richer than previously reported, and we propose the possibility of up to four different sub-phases within the medium-to-high nutrient concentration regime. We hypothesize that the quenched disorder that characterizes one of these sub-phases is an emergent property of the growth and division of bacteria competing for limited space and nutrients.

Physics in Universe's Youth  

NASA Astrophysics Data System (ADS)

Using a quasar located 12.3 billion light-years away as a beacon, a team of astronomers detected the presence of molecular hydrogen in the farthest system ever, an otherwise invisible galaxy that we observe when the Universe was less than 1.5 billion years old, that is, about 10% of its present age. The astronomers find that there is about one hydrogen molecule for 250 hydrogen atoms. A similar set of observations for two other quasars, together with the most precise laboratory measurements, allows scientists to infer that the ratio of the proton to electron masses may have changed with time. If confirmed, this would have important consequences on our understanding of physics. "Detecting molecular hydrogen and measuring its properties in the most remote parts of the Universe is important to understand the gas environment and determine the rate of star formation in the early Universe", said Cédric Ledoux, lead-author of the paper presenting the results [1]. Although molecular hydrogen is the most abundant molecule in the Universe, it is very difficult to detect directly. For the time being, the only way to detect it directly in the far Universe is to search for its telltale signatures in the spectra of quasars or gamma-ray burst afterglows. This requires high spectral resolution and large telescopes to reach the necessary precision. A team of astronomers, comprised of Cédric Ledoux (ESO), Patrick Petitjean (IAP, Paris, France) and Raghunathan Srianand (IUCAA, Pune, India), is conducting a survey for molecular hydrogen at high redshift using the Ultraviolet and Visible Echelle Spectrograph (UVES) at ESO's Very Large Telescope. Out of the 75 systems observed up to now, 14 have firm detection of molecular hydrogen. Among these, one is found having a redshift of 4.224. While using the 12.3 billion light-years distant quasar PSS J 1443+2724 as a beacon, the astronomers detected several features belonging to an unseen galaxy having a redshift of 4.224. In particular, many lines from molecular hydrogen were found, breaking the record for the detection of this element in the farthest object in the Universe. This also implies that the gas in this galaxy must be rather cold, about -90 to -180 degrees Celsius. ESO PR Photo 1r/06 Molecular Hydrogen in Distant Galaxy In addition, several lines from 'metals' are also seen, allowing the researchers to deduce the amount of various chemical elements. "From the abundance of Nitrogen observed, we argue that it had to be produced in the late stage of the life of 4 to 8 solar mass stars," said Patrick Petitjean. "Thus, star-formation activity must have formed at least 200 to 500 million years before we are observing the galaxy, that is, when the Universe was about one billion years old" [2]. If the galaxy went through a phase of intense star-formation activity, it is now, at the time of the observations, in a rather quiescent state. "These observations demonstrate the possibility to perform these studies at the highest redshift with ESO's VLT", said Raghunathan Srianand. "In particular, the possibility to observe the interstellar medium of distant galaxies revealed by using gamma-ray bursts as beacons will boost this field in the near future." [3] A similar set of accurate measurements of molecular hydrogen lines was made by the astronomers [4] with UVES on the VLT towards two others quasars, Q 0405-443 and Q 0347-383. This set of data allowed the scientists to compare the ratio of the mass of a proton to that of an electron in molecular hydrogen as it is now and how it was about 12 billion years ago [5]. To this aim, they performed extremely accurate measurements of spectral lines of hydrogen molecules in the laboratory and compared the results with the same lines observed in the spectra of these quasars. These measurements show that the mass ratio of the proton and the electron may have changed, becoming 0.002% smaller in the past twelve billion years. Albeit such a change may look tiny, it would have important consequences on our understa

Plasma and the universe  

SciTech Connect

Hannes Alfven has enjoyed a long and spectacular career in which he has time and again pioneered the path that other workers were able fruitfully to exploit. One thinks of the Alven waves, the concept of gyrocenter drift and the perturbation theory based on it, and the critical velocity phenomenon in the interaction of a plasma with a neutral gas. All of these discoveries have been of fundamental importance. By no means content to rest on his laurels, Alfven has, during the last decade, contributed to science in a major sense, especially in the field of cosmogeny. For example, he has used the latest data from the Voyager spacecraft to test his detailed predictions of the structure of the Saturnian rings. Alfven's current preoccupation is with the Plasma Universe and, as may be expected, some of his concepts are receiving observational support, while others are still controversial.

Self-Accelerated Universe  

NASA Astrophysics Data System (ADS)

It is widely believed that the large redshifts for distant supernovae are due to the vacuum energy dominance, which is responsible for the anti-gravitation effect. A tacit assumption is that particles move along geodesics for the background metric. This is in the same spirit as the consensus regarding the uniform Galilean motion of a free electron. However, apart from the Galilean solution, there is a self-accelerated solution to the Lorentz-Dirac equation governing the behavior of a radiating electron. Likewise, a runaway solution to the entire system of equations, both gravitation and matter equations of motion including, may exist, which provides an alternative explanation for the accelerated expansion of the Universe.

European Universe Awareness  

NASA Astrophysics Data System (ADS)

The European Universe Awareness (EU-UNAWE) programme uses the beauty and grandeur of the cosmos to encourage young children, particularly those from underprivileged backgrounds, to develop an interest in science and technology and to foster a sense of global citizenship. EU-UNAWE is already active in 40 countries and comprises a global network of almost 500 astronomers, teachers and other educators. The programme was recently awarded a grant of 1.9 million euros by the European Union so that it can be further developed in five European countries and South Africa. The grant will be used to organise teacher training workshops and to develop educational materials, such as an astronomy news service for children and games. During this presentation we will outline some of the biggest achievements of EU-UNAWE to date and discuss future plans for the programme.

Supply Side University  

NSDL National Science Digital Library

Those who are interested in the intricacies of supply-side economics will find Jude Wanniski's Supply Side University a useful site for understanding the concepts of this theory. Wanniski, a well-known supply-side advocate, maintains SSU as a free "weekend school in supply-side economics," where the subject is taught in a political context. Included at present are four essays and 23 lessons ranging from It's Time to Cut Taxes, to The World Trade Deficit, to Say's Law of Markets, to Two Kinds of Deflation (or Inflation). Much of the content is derived from Wanniski's articles in The Wall Street Journal and from his well-known book The Way the World Works. Lessons are driven by user questions, and Wanniski encourages "economists trained in Keynesian or monetarist theory [to] sneak in without embarrassment."

Universal Landau pole.  

PubMed

Our understanding of quantum gravity suggests that at the Planck scale the usual geometry loses its meaning. If so, the quest for grand unification in a large non-Abelian group naturally endowed with the property of asymptotic freedom may also lose its motivation. Instead, we propose a unification of all fundamental interactions at the Planck scale in the form of a universal Landau pole, at which all gauge couplings diverge. The Higgs quartic coupling also diverges while the Yukawa couplings vanish. The unification is achieved with the addition of fermions with vector gauge couplings coming in multiplets and with hypercharges identical to those of the standard model. The presence of these particles also prevents the Higgs quartic coupling from becoming negative, thus avoiding the instability (or metastability) of the standard model vacuum. PMID:23862991

Brane Universe: Global Geometry  

SciTech Connect

The global geometries of bulk vacuum space-times in the brane-universe models are investigated and classified in terms of geometrical invariants. The corresponding Carter-Penrose diagrams and embedding diagrams are constructed. It is shown that for a given energy-momentum induced on the brane there can be different types of global geometries depending on the signs of a bulk cosmological term and surface energy density of the brane (the sign of the latter does not influence the internal cosmological evolution). It is shown that in the Randall-Sundrum scenario it is possible to have an asymmetric hierarchy splitting even with a Z{sub 2}-symmetric matching of 'our' brane to the bulk.

Some toy sheet universes  

NASA Astrophysics Data System (ADS)

Our model is based on the model studied by Langer [1] and in more detail by Langer and Žofka [2]. In these papers we studied a toy closed universe which is flat except of a thin spherical shell. The model was constructed in the framework of the Israel formalism [3]. In this approach the history of a thin shell of matter is described by the time-like hypersurface ? which divides the spacetime into two parts V- and V+. The hypersuface ? is a common boundary of V- and V+ consequently its intrinsic metric induced by the geometries in both regions must be the same. However, the extrinsic curvatures of ? in V- and V+ are in general different. The jump in projections of the extrinsic curvature tensors on ? determines the surface energy-momentum tensor of matter on ?.

Fred Hoyle's Universe  

NASA Astrophysics Data System (ADS)

Fred Hoyle was a Yorkshire truant who became the voice of British astronomy. For fifty years, he spoke out for astronomy in the newspapers, on government committees, at scientific meetings, in popular books and on the radio. He devised a never-ending history of the universe, and worked out how the elements were made. He founded a prestigious institute for theoretical astronomy and built a giant telescope, and if it rained on his summer holiday, he sat in his caravan and wrote science fiction novels for his legions of fans around the world. Fred Hoyle also claimed that diseases fall from the sky, that the big bang never happened, and that the Astronomer Royal should be abolished. When the outspoken Fred Hoyle spoke out for astronomy, some astronomers really wished he had kept his mouth shut. This book tells the behind-the-scenes story of Hoyle's widely acclaimed and deeply controversial role in the ideas, organization and public face of astronomy in post-war Britain. It chronicles the triumphs, acrimony, jealousies, rewards and bitter feuds of a field in turmoil, and meets the astronomers, contemplating cosmic questions, keeping secrets, losing their tempers, winkling information out of distant stars and, over tea on the lawn, discussing the finer points of libel law. Fred Hoyle's Universe draws on previously confidential government documents, recently released personal correspondence and interviews with Hoyle's friends, colleagues and critics, as well as with Hoyle himself, to bring you the man, the science, and the scandal behind the genial and genteel facade of the most exciting period in the history of astronomy.

Acceleration of Black Hole Universe  

NASA Astrophysics Data System (ADS)

An alternative cosmological model called black hole universe has been recently proposed by the author. According to this model, the universe originated from a hot star-like black hole, and gradually grew up through a supermassive black hole to the present state by accreting ambient materials and merging with other black holes. The entire space is structured with an infinite number of layers hierarchically. The innermost three layers are the universe that we live, the outside space called mother universe, and the inside star-like and supermassive black holes called child universes. The outermost layer has an infinite radius and limits to zero for both the mass density and absolute temperature. All layers or universes are governed by the same physics, the Einstein general theory of relativity with the Robertson-Walker metric of space-time, and tend to expand outward physically. The evolution of the space structure is iterative. When one universe expands out, a new similar universe grows up from its inside. In this study. we will analyze the acceleration of black hole universe that accretes its ambient matter in an increasing rate. We will also compare the result obtained from the black hole universe model with the measurement of type Ia supernova and the result from the big bang cosmology.

Quantization of Bianchi type universe  

NASA Astrophysics Data System (ADS)

In this paper we have used the square root formulation of the Wheeler-De Witt equation to quantize a minisuperspace consisting of the Bianchi Type-I universe and a source of radiation field. We have derived a wavefunction of the universe with a conserved current and a positive-definite probability density. We have also explored the quantization of Bianchi Type-III universe using a procedure similar to that used in the ordinary quantum theory in curved spacetime. We have given the wavefunction satisfied by the Wheeler-De Witt equation. Regarding the wavefunction as an operator in a minisuperspace we have not only avoided the difficulty of probabilistic interpretation in quantum cosmology, but also obtained the conclusion of multiple production of universe. We have estimated the mean numbers of various types of universes generated from nothing and shown the distribution of the generated universes to be Planckian.

Universal mechatronics coordinator  

NASA Astrophysics Data System (ADS)

Mechatronic systems incorporate multiple actuators and sensor which must be properly coordinated to achieve the desired system functionality. Many mechatronic systems are designed as one-of-a-kind custom projects without consideration for facilitating future system or alterations and extensions to the current syste. Thus, subsequent changes to the system are slow, different, and costly. It has become apparent that manufacturing processes, and thus the mechatronics which embody them, need to be agile in order to more quickly and easily respond to changing customer demands or market pressures. To achieve agility, both the hardware and software of the system need to be designed such that the creation of new system and the alteration and extension of current system is fast and easy. This paper describes the design of a Universal Mechatronics Coordinator (UMC) which facilitates agile setup and changeover of coordination software for mechatronic systems. The UMC is capable of sequencing continuous and discrete actions that are programmed as stimulus-response pairs, as state machines, or a combination of the two. It facilitates the modular, reusable programing of continuous actions such as servo control algorithms, data collection code, and safety checking routines; and discrete actions such as reporting achieved states, and turning on/off binary devices. The UMC has been applied to the control of a z- theta assembly robot for the Minifactory project and is applicable to a spectrum of widely differing mechatronic systems.

Hydrogen fuel - Universal energy  

NASA Astrophysics Data System (ADS)

The technology for the production, storage, transmission, and consumption of hydrogen as a fuel is surveyed, with the physical and chemical properties of hydrogen examined as they affect its use as a fuel. Sources of hydrogen production are described including synthesis from coal or natural gas, biomass conversion, thermochemical decomposition of water, and electrolysis of water, of these only electrolysis is considered economicially and technologically feasible in the near future. Methods of production of the large quantities of electricity required for the electrolysis of sea water are explored: fossil fuels, hydroelectric plants, nuclear fission, solar energy, wind power, geothermal energy, tidal power, wave motion, electrochemical concentration cells, and finally ocean thermal energy conversion (OTEC). The wind power and OTEC are considered in detail as the most feasible approaches. Techniques for transmission (by railcar or pipeline), storage (as liquid in underwater or underground tanks, as granular metal hydride, or as cryogenic liquid), and consumption (in fuel cells in conventional power plants, for home usage, for industrial furnaces, and for cars and aircraft) are analyzed. The safety problems of hydrogen as a universal fuel are discussed, noting that they are no greater than those for conventional fuels.

Viscous dark fluid universe  

SciTech Connect

We investigate the cosmological perturbation dynamics for a universe consisting of pressureless baryonic matter and a viscous fluid, the latter representing a unified model of the dark sector. In the homogeneous and isotropic background the total energy density of this mixture behaves as a generalized Chaplygin gas. The perturbations of this energy density are intrinsically nonadiabatic and source relative entropy perturbations. The resulting baryonic matter power spectrum is shown to be compatible with the 2dFGRS and SDSS (DR7) data. A joint statistical analysis, using also Hubble-function and supernovae Ia data, shows that, different from other studies, there exists a maximum in the probability distribution for a negative present value q{sub 0{approx_equal}}-0.53 of the deceleration parameter. Moreover, while previous descriptions on the basis of generalized Chaplygin-gas models were incompatible with the matter power-spectrum data since they required a much too large amount of pressureless matter, the unified model presented here favors a matter content that is of the order of the baryonic matter abundance suggested by big-bang nucleosynthesis.

Quantum entanglement of baby universes  

SciTech Connect

We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in type IIA string theory compactified on the local Calabi-Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G=1 in hep-th/0504221. Non-perturbative terms can be organized into a sum over contributions from baby universes, and the total wave-function is their coherent superposition in the third quantized Hilbert space. We find that half of the universes preserve one set of supercharges while the other half preserve a different set, making the total universe stable but non-BPS. The parent universe generates baby universes by brane/anti-brane pair creation, and baby universes are correlated by conservation of non-normalizable D-brane charges under the process. There are no other source of entanglement of baby universes, and all possible states are superposed with the equal weight.

The age of universe  

NASA Astrophysics Data System (ADS)

The presence of short-lived isotope Curium-247 in the early Solar System complicates the job of dating the earliest events in the solar nebula. Primitive components in meteorites contain a detailed record of the conditions and processes in the solarnebula, the cloud of dust and gas surrounding the infant Sun. Determining accurately when the first materialsformed re-quires the lead-lead (Pb-Pb) dating method, a method based on the decay of uranium (U) isotopes toPb isotopes. The initial ratio of U-238 to U-235 is critical to determining theages correctly, and many studies have concluded that the ratio is constant for any given age. How-ever, my colleagues at Arizona State University(Frankfurt, Germany), and the Senckenberg Forschungsinstitut und Naturmuseum (also in Frankfurt) and I have found that some calcium-aluminum-rich inclusions (CAIs) in chondritic meteorites deviate from the conventional value for the U-238/U-235 ratio. This could lead to inaccuracies of up to 5 million years in the age of these objects, if no correction is made.Variations in the concentrations of thorium and neodymium with the U-238/U-235 ratio suggest that the ratio may have been lowered by the decay of curium-247, which decays to U-235 with a half-life of 15.6 million years. Curium-247 is created in certain types of energetic supernovae, so its presence suggests that a supernova added material to the pre-solar interstellar cloud between 110 and 140 million years before theSolar System began to form.

The Universe: An Introduction  

NSDL National Science Digital Library

Astronomy is a science that asks fundamental questions about the very fundament of things, the universe. How big and how far away are the planets and stars? How did they form and when? How do they move and why? Finding answers to those questions has been the highest adventure of the human mind, and yet the questions, in essence, are those of any child looking into the sky. The lessons in this issue of Smithsonian in Your Classroom address the questions, therefore, by first asking the students.In Lesson 1, the class works together to arrange pictures from space according to the studentsâ best ideas of size, distance, and age. This active introduction to the cosmos can be a pre-assessment for a unit on space science. Lesson 2 is a modeling exercise in which relationships in space are brought down to a scale of two inches. Both lessons are based on educational materials created by the Smithsonian Astrophysical Observatory, in cooperation with NASA. All images needed for the lessons can be downloaded from this page.The issue also includes a profile of Smithsonian astronomer Lisa Kaltenegger, who is in the burgeoning business of âÂÂplanet huntingâÂÂâÂÂthe discovery of planets outside of our solar system. The first âÂÂexoplanetâ was discovered in 1995. There have been hundreds of discoveries since. The work is bringing closer to the fore a question in the back of anyoneâÂÂs mind when looking at the sky: Is anyone else out there?

[Universal electrogustometer EG-1].  

PubMed

Electrogustometry has been used as a clinical tool for diagnosis and assessment of a variety of conditions. Since the lack of versatile electrogustometer for research and diagnosis, the new electrogustometer EG-1 was developed in 2006. It was done in cooperation between Warsaw University of Technology and Military Institute of Medicine in Warsaw. EG-1 allows quantitative estimation of taste perception threshold using both static and impulse electrogustometry with bipolar electrode. It is a fully autonomous, battery powered and portable instrument. Because of small size and weight, it can be easily placed in any environment. Microprocessor controlled measurement system and user-friendly interface (LCD display with simple keyboard) make EG-1 electrogustometer very handy and flexible in operation. Data obtained during measurements is stored in the internal device memory. After taste examinations measurement data can be transferred to a personal computer via inbuilt USB port for further analysis and storage. EG-1 can generate three predefined variously shaped current impulses: sinus-, saw- and rectangle-shaped. There is an optional possibility of creating own shapes of stimulus puls by the user. The electrical parameters of generated pulses are as follow: current amplitude 1-2000 microA regulated with 1 microA step, stimulus frequency 0(DC)-500 Hz regulated with 5 Hz step, controlable fulfillment factor and signal rise time (optional for automatic measurements). The operator can trigger the stimuli via a hand switch on the bipolar electrode (with gold-plated endings), via keyboard or via additional independent hand switch. Three years of experience collected during EG-1 exploitation allowed to design a new version of electrogustometer EG-2 with a touch panel and color graphical display. PMID:19886533

Entropy of viscous Universe models  

NASA Astrophysics Data System (ADS)

The cosmological event horizon entropy and the apparent horizon entropy of the ?CDM and the Bianchi type I Universe model with viscosity has been calculated numerically, and analytically in the large time limit. It is shown that for these Universe models the cosmological event horizon entropy increases with time and for large times it approaches a finite maximum value. The effect of viscosity upon the entropy is also studied and we have found that its role is to decrease the entropy. The bigger the viscosity coefficient is the less the entropy will be. Furthermore, the radiation entropy for the ?CDM Universe model with and without viscosity is investigated, and together with the cosmological event horizon entropy are used to examine the validity of the generalized second law of thermodynamics, which states that the total rate of change of entropy of the Universe is never negative, in this Universe model.

Acceleration of black hole universe  

NASA Astrophysics Data System (ADS)

Recently, Zhang slightly modified the standard big bang theory and developed a new cosmological model called black hole universe, which is consistent with Mach's principle, governed by Einstein's general theory of relativity, and able to explain all observations of the universe. Previous studies accounted for the origin, structure, evolution, expansion, and cosmic microwave background radiation of the black hole universe, which grew from a star-like black hole with several solar masses through a supermassive black hole with billions of solar masses to the present state with hundred billion-trillions of solar masses by accreting ambient matter and merging with other black holes. This paper investigates acceleration of the black hole universe and provides an alternative explanation for the redshift and luminosity distance measurements of type Ia supernovae. The results indicate that the black hole universe accelerates its expansion when it accretes the ambient matter in an increasing rate. In other words, i.e., when the second-order derivative of the mass of the black hole universe with respect to the time is positive ddot{M}(t) > 0. For a constant deceleration parameter q = -M(t) ddot{M}(t)/dot{M}(t) ˜-0.6, we can perfectly explain the type Ia supernova measurements with the reduced chi-square to be very close to unity, ? red˜1.0012. The expansion and acceleration of black hole universe are driven by external energy.

Constraining the universal lepton asymmetry  

NASA Astrophysics Data System (ADS)

The relic cosmic background neutrinos accompanying the cosmic microwave background (CMB) photons may hide a universal lepton asymmetry orders of magnitude larger than the universal baryon asymmetry. At present, the only direct way to probe such an asymmetry is through its effect on the abundances of the light elements produced during primordial nucleosynthesis. The relic light element abundances also depend on the baryon asymmetry, parameterized by the baryon density parameter (\\eta_{\\mathrm {B}} \\equiv n_{\\mathrm {B}}/n_{\\gamma } ) and on the early-universe expansion rate, parameterized by the expansion rate factor (S \\equiv H'/H ) or, equivalently, by the effective number of neutrinos (N_{\

Universality of hypercubic random surfaces  

NASA Astrophysics Data System (ADS)

We study universality properties of the Weingarten hyper-cubic random surfaces. Since a long time the model of hypercubic random surfaces with a local restriction forbidding surface self-bendings was thought to be in a different universality class from the unrestricted model defined on the full set of surfaces. In this paper we show that both models in fact belong to the same universality class with the entropy exponent ? = 1/(2) and differ by the finite size effects which are much more pronounced in the restricted model.

All physical systems register and process information. The laws of physics determine the amount of information that a physical system can register (number of bits) and the number of elementary logic operations that a system can perform (number of ops). The Universe is a physical system. The amount of information that the Universe can register and the number of elementary operations that it can have performed over its history are calculated. The Universe can have performed 10120 ops on 1090 bits ( 10120 bits including gravitational degrees of freedom).

Complexity, universality and intermediate degrees  

NASA Astrophysics Data System (ADS)

This paper is a philosophical account of complexity versus universality. It seems sustainable to equate universal systems to complex systems or at least to potentially complex systems. Post's problem on the existence of (natural) intermediate degrees (between decidable and universal ?01) then finds its analog in the Principle of Computional Equivalence (PCE). In this abstract we address possible driving forces -if any- behind PCE. Both the natural aspects as well as the cognitive ones are investigated. We postulate a principle GNS that we call the Generalized Natural Selection principle that together with the Church-Turing thesis is seen to be equivalent in a sense to a weak version of PCE.

Universal planetary tectonics (supertectonics)  

NASA Astrophysics Data System (ADS)

Universal planetary tectonics (supertectonics) G. Kochemasov IGEM of the Russian Academy of Sciences, Moscow, Russia, kochem.36@mail.ru The wave planetology [1-3 & others] proceeds from the following: "planetary structures are made by orbits and rotations". A uniform reason makes uniform structures. Inertia-gravity waves arising in planetary bodies due to their movements in Keplerian elliptical orbits with periodically changing accelerations warp these bodies in such way that they acquire polyhedron shapes (after interference of standing waves of four directions). Strong Newtonian gravity makes bodies larger than ~400 to 500 km in diameter globular and polyhedra are rarely seen. Only geomorphologic, geologic and geophysical mapping can develop these hidden structures. But small bodies, normally less than ~ 300 to 400 km in diameter, often show parts of the polyhedra, rarely fully developed forms (the asteroid Steins and satellite Amalthea present rather perfect forms of "diamond"). Depending on warping wavelengths (they make harmonics) various Plato's figures superimposed on each other can be distinguished. The fundamental wave 1 produces a tetrahedron, intrinsically dichotomic figure in which a vertex (contraction) always is opposed to a face (expansion). From the recent examples the best is the saturnian northern hexagon (a face) opposed to the southern hurricane (a vertex). The first overtone wave 2 is responsible for creation of structural octahedra. Whole ‘diamonds" and their parts are known [4, 5]. Other overtones produce less developed (because of smaller wave amplitudes) planetary shapes complicating main forms. Thus, the first common structural peculiarity of planetary bodies is their polyhedron nature. Not less important is the second common structural peculiarity. As all globular or smaller more or less isometric bodies rotate, they have an angular momentum. It is inevitably different in tropic and extra-tropic belts having uneven radii or distances to the rotation axe. But this unevenness is undesirable because it creates tectonic stresses and increases energetic status that is against the natural tendency to minimize these physical characteristics. So, a body tends to lower angular momentum of tropics and increase it in extra-tropics. With the same angular velocity it remains only mass and radius to play in this tendency. Tropical belt is destructed (for an example, the lithosphere disintegration in solid bodies), extra-tropical belts add dense material (plumes), expand - the constructive tendency [6]. Both tectonic peculiarities-polyhedrons and constructive - destructive tendencies - are common for celestial bodies of various classes. They are characteristic for our star, planets, satellites and small bodies. That is why a term "supertectonics" seems rather suitable. References: [1] Kochemasov G.G.

Astronomy in the Digital Universe  

NASA Astrophysics Data System (ADS)

The Digital Universe is an Internet project whose mission is to provide free, accurate, unbiased information covering all aspects of human knowledge, and to inspire humans to learn, make use of, and expand this knowledge. It is planned to be a decades long effort, inspired by the Encyclopedia Galactica concept popularized by Carl Sagan, and is being developed by the non-profit Digital Universe Foundation. A worldwide network of experts is responsible for selecting content featured within the Digital Universe. The first publicly available content is the Encyclopedia of Earth, a Boston University project headed by Prof. Cutler Cleveland, which will be part of the Earth Portal. The second major content area will be an analogous Encyclopedia of the Cosmos to be part of the Cosmos Portal. It is anticipated that this will evolve into a major resource for astronomy education. Authors and topic editors are now being recruited for the Encyclopedia of the Cosmos.

Neutrinos in the early universe  

NASA Astrophysics Data System (ADS)

The neutrinos from the Big Bang or the Cosmic Neutrino Background (CNB) carry precious information from the early epoch when our universe was only 1 s old. Although not yet directly detected, CNB may be revealed indirectly through cosmological observations due to neutrino important cosmological influence.We review the cosmological role of neutrinos and the cosmological constraints on neutrino characteristics. Namely, we discuss the impact of neutrinos in the early universe: the cosmic expansion, neutrino decoupling, the role of neutrinos in the primordial production of light elements, leptogenesis, etc. We briefly discuss the role of neutrino at later stages of the universe.Due to the considerable cosmological influence of neutrinos, cosmological bounds on neutrino properties from observational data exist. We review the cosmological constraints on the effective number of neutrino species, neutrino mass and mixing parameters, lepton number of the universe, presence of sterile neutrino, etc.

We report a 3-year-old boy born with light brown skin that progressively became much darker. The color change was insidious in onset at the age of 3 months, asymptomatic, and progressive involving the entire body surface. Hyperpigmentation may be congenital or acquired, hereditary or nonhereditary, localized or universal, of known or unknown origin. Universal acquired melanosis is a rare form of hyperpigmentation, which has been synonymously referred to as ''carbon baby.'' PMID:24010507

In this proceeding, the phenomenology of Universal Extra Dimensions (UED), in which all the Standard Model fields propagate, is explored. We focus on models with one universal extra dimension, compactified on an S{sub 1}/Z{sub 2} orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

A Universe without Weak Interactions  

SciTech Connect

A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical ''Weakless Universe'' is matched to our Universe by simultaneously adjusting Standard Model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the Weakless Universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multi-parameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure. The fine-tuning problems associated with the electroweak breaking scale and the cosmological constant therefore appear to be qualitatively different from the perspective of obtaining a habitable universe.

Universal particle flux pressure converter  

US Patent & Trademark Office Database

The design of Shaded Rotor devices to demonstrate the existence of a hypothetical Universal Particle Flux Field is presented. These devices should extract a measurable amount of energy from this Field. We believe the Universal Particle Flux Field can explain all invisible forces at a distance phenomena between masses, charged bodies, and magnetic materials. We propose that the Universal Particle Flux Field is a simultaneously convergent/divergent field, where the particle streams traverse to any point in the Universe from every other point in the Universe. The order of this Flux Field is a nearly perfect disorder, which is an order in itself. The strength of the gravitational component of this Field is conventionally denoted by "G". Two neutral masses immersed in such Flux Field will develop forces between them, which are consistent with Newton's Equation of Gravitation. This Field is also consistent with Electrostatic, and Magnetic Force Equations. A magnetic rotor is preferentially shaded with a magnetic stator so that a net torque exists on the rotor. This principle is also applied to an electrostaticly charged Shaded Rotor device. The possibilities that the Beta, the Muon, and the Tau Neutrinos are the Universal Particles and they are producing the Electrostatic, Magnetic, and Gravitational Force Fields respectively, are explored. Laboratory sized Shaded Rotor Devices can be constructed using magnetic and/or electrostatic components; detailed designs are described herein. Circumstantial evidences described herein, indicate that the Universal Gravitational Constant "G" hence the "g" of the Earth is direction and time variable, and it has significantly increased during the last several hundred million years; this may account for the demise of the Dinosaurs, and of the giant vegetation.

Traveling in the Computational Universe  

NASA Astrophysics Data System (ADS)

The concept of travel, specifically ``space travel'', cannot be separated from the concept of ``Universe'', because the Universe is where space and time acquire their significance, along with their properties, possibilities and limitations. Mankind is strongly focused on a four dimensional Universe, with its Lorentzian or Euclidean interpretation. It is still a puzzle about the fact that the four dimensional Universe seems to have a beginning, therefore there seem to be boundaries in space-time and we would like to know the nature of those boundaries and its endpoints. To better understand the deep significance of our best physical theories it could be interesting to compare our Universe with its models. It may happen that the differences between the model and reality can be made indistinguishable, to the point that it may seem acceptable to consider reality as a gigantic program, a ``mother computation'' running in a Universal Computer. The computational interpretation of reality is here adopted for introducing concepts that are common in computer science, they may offer a new insight. For instance, code and memory usage optimization techniques are common in computer science because they improve the performances at a reduced hardware cost. According to the concepts discussed in this paper, the possibility of recognizing the effects of optimization rules in a physical reality will allow us to discriminate if our reality is fundamental or the result of a large computation. Conversely, code and memory optimization has side effects, if it is present in our Universe it can produce many interesting phenomena, some seem readily recognizable, others only wait to be discovered. The science of Space Travel appears suitable for the experimental test of these conceptualizations.

Interdimensional universality of dynamic interfaces.  

PubMed

Despite the complexity and diversity of nature, there exists universality in the form of critical scaling laws among various dissimilar systems and processes such as stock markets, earthquakes, crackling noise, lung inflation and vortices in superconductors. This universality is mainly independent of the microscopic details, depending only on the symmetry and dimension of the system. Exploring how universality is affected by the system dimensions is an important unresolved problem. Here we demonstrate experimentally that universality persists even at a dimensionality crossover in ferromagnetic nanowires. As the wire width decreases, the magnetic domain wall dynamics changes from elastic creep in two dimensions to a particle-like stochastic behaviour in one dimension. Applying finite-size scaling, we find that all our experimental data in one and two dimensions (including the crossover regime) collapse onto a single curve, signalling universality at the criticality transition. The crossover to the one-dimensional regime occurs at a few hundred nanometres, corresponding to the integration scale for modern nanodevices. PMID:19360082

Tuning universality far from equilibrium.  

PubMed

Possible universal dynamics of a many-body system far from thermal equilibrium are explored. A focus is set on meta-stable non-thermal states exhibiting critical properties such as self-similarity and independence of the details of how the respective state has been reached. It is proposed that universal dynamics far from equilibrium can be tuned to exhibit a dynamical transition where these critical properties change qualitatively. This is demonstrated for the case of a superfluid two-component Bose gas exhibiting different types of long-lived but non-thermal critical order. Scaling exponents controlled by the ratio of experimentally tuneable coupling parameters offer themselves as natural smoking guns. The results shed light on the wealth of universal phenomena expected to exist in the far-from-equilibrium realm. PMID:23928853

Big questions about the universe  

NASA Astrophysics Data System (ADS)

Astronomy is not only a branch of science but also an important part of the culture and civilisations of peoples. Starting with archeoastronomy to the present day, it has always contributed to a better understanding of life, of humanity. After 400 years of modern astronomy, it still addresses major problems such as: Why there is something rather than nothing? Why is nature comprehensible to humans? How is cosmos related to humanity? Do multiverses exist? Is there life on other planets? Are we alone in the universe? Does the universe have a beginning? If so, what does it mean? How did the universe originate? All these questions are a challenge for interdisciplinary and transdisciplinary investigations, for philosophers, physicists, cosmologists, mathematicians, theologians. The new insights gained by pursuing in depth these common investigations will shape the society we live in and have important consequences on the future we are creating.

Dark matter in the universe  

NASA Astrophysics Data System (ADS)

What is the quantity and composition of material in the Universe? This is one of the most fundamental questions we can ask about the Universe, and its answer bears on a number of important issues including the formation of structure in the Universe, and the ultimate fate and the earliest history of the Universe. Moreover, answering this question could lead to the discovery of new particles, as well as shedding light on the nature of the fundamental interactions. At present, only a partial answer is at hand. Most of the radiation in the Universe does not give off detectable radiation; it is dark. The dark matter associated with bright galaxies contributes somewhere between 10 and 30 percent of the critical density; baryonic matter contributes between 1.1 and 12 percent of the critical. The case for the spatially flat, Einstein-de Sitter model is supported by three compelling theoretical arguments - structure formation, the temporal Copernican principle, and inflation - and by some observational data. If Omega is indeed unity, or even just significantly greater than 0.1, then there is a strong case for a Universe comprised of nonbaryonic matter. There are three well motivated particle dark matter candidates: an axion of mass 10 -6 eV to 10 -4 eV; a neutrino of mass 10 GeV to about 3 TeV; or a neutrino of mass 20 eV to 90 eV. All three possibilities can be tested by experiments that are either planned or are underway.

Universe Awareness For Young Children  

NASA Astrophysics Data System (ADS)

Universe Awareness (UNAWE) is an international programme that will expose economically disadvantaged young children aged between 4 and 10 years to the inspirational aspects of modern astronomy. The programme is motivated by the premise that access to simple knowledge about the Universe is a basic birth right of everybody. These formative ages are crucial in the development of a human value system. This is also the age range in which children can learn to develop a 'feeling' for the vastness of the Universe. Exposing young children to such material is likely to broaden their minds and stimulate their world-view. The goals of Universe Awareness are in accordance with two of the United Nations Millennium goals, endorsed by all 191 UN member states, namely (i) the achievement of universal primary education and (ii) the promotion of gender equality in schools. We propose to commence Universe Awareness with a pilot project that will target disadvantaged regions in about 4 European countries (possibly Spain, France, Germany and The Netherlands) and several non-EU countries (possibly Chile, Colombia, India, Tunisia, South Africa and Venezuela). There will be two distinct elements in the development of the UNAWE program: (i) Creation and production of suitable UNAWE material and delivery techniques, (ii) Training of educators who will coordinate UNAWE in each of the target countries. In addition to the programme, an international network of astronomy outreach will be organised. We present the first results of a pilot project developed in Venezuela, where 670 children from different social environments, their teachers and members of an indigenous tribe called Ye´kuana from the Amazon region took part in a wonderful astronomical and cultural exchange that is now being promoted by the Venezuelan ministry of Education at the national level.

Geometry for the accelerating universe  

SciTech Connect

The Lorentzian spacetime metric is refined to an area metric which naturally emerges as a generalized geometry in quantum string and gauge theory. Employing the area metric curvature scalar, the Einstein-Hilbert gravitational action is reinterpreted as dynamics for an area metric. The area metric cosmology of the radiation-dominated early universe does not depart from general relativity, enabling successful nucleosynthesis. But intriguingly, without the need for dark energy or fine-tuning, area metric cosmology explains the observed small acceleration of the late universe.

Can the universe afford inflation?  

SciTech Connect

Cosmic inflation is envisioned as the 'most likely' start for the observed universe. To give substance to this claim, a framework is needed in which inflation can compete with other scenarios and the relative likelihood of all scenarios can be quantified. The most concrete scheme to date for performing such a comparison shows inflation to be strongly disfavored. We analyze the source of this failure for inflation and present an alternative calculation, based on more traditional semiclassical methods, that results in inflation being exponentially favored. We argue that reconciling the two contrasting approaches presents interesting fundamental challenges, and is likely to have a major impact on ideas about the early universe.
