A catalogue of symbiotic stars

We present a new catalogue of symbiotic stars. In our list we include 188 symbiotic stars as well as 28 objects suspected of being symbiotic. For each star, we present basic observational material: coordinates, V and K magnitudes, ultraviolet (UV), infrared (IR), X-ray and radio observations. We also list the spectral type of the cool component, the maximum ionization potential observed, references to finding charts, spectra, classifications and recent papers discussing the physical parameters and nature of each object. Moreover, we present the orbital photometric ephemerides and orbital elements of known symbiotic binaries, pulsational periods for symbiotic Miras, Hipparcos parallaxes and information about outbursts and flickering.Comment: 32 pages, submitted to AA

Investigation of Glacial Retreat, Terrace Abandonment, and Catchment-wide Denudation Rates in the Vakhsh Catchment, Tajikistan

The development of the Vakhsh catchment is linked to the tectonic development of the Pamir during the India-Asia collision. The northward motion of the Pamir block relative to Eurasia, as well as its uplift and shortening, confined the Vakhsh River system between the western Tian Shan and the Pamir along the Pamir Thrust System deformation zone (PTS). The northern Pamir overthrusts the western Tian Shan and the Alai Valley experiences shortening along the PTS. At the present, the Vakhsh catchment drains two orogens along a thrust system and provides an opportunity for understanding denudation associated with plate convergence. During the Quaternary, the Vakhsh River catchment experienced changes in climatic conditions such as Quaternary glaciation and the Holocene thermal optimum, which caused fluctuations in sediment supply and water discharge. This study investigates the timing of glaciation, terrace formation as well as modern and paleo-denudation rates in the context of the tectonic and paleo-climatic conditions of the region. Glacial deposits, such as moraines, are archives that record advance and retreat cycles driven by climate change. Collecting spatial and temporal data about glaciations is essential for the reconstruction of both, the regional and global timing of ice ages and climate change. The investigation of glacial extent and timing in the Vakhsh River catchment was addressed by studying the glacial deposits near the former terminus of the Fedchenko Glacier. The Fedchenko Glacier is particularly important for understanding the glacial chronology in Central Asia, because it is the longest (~72 km) glacier outside the Polar Regions and the timing of its advance and retreat may be representative for the climate evolution of the Westerly-dominated Central Asia region. The present-day climate is dominated by the Mid-Latitude Westerlies and supplies the region with 400 – 1,000 mm annual precipitation. The present-day mean annual temperatures range between -6.7 and 12 ˚C. Inter alia, the interaction between precipitation and temperature induces flooding and increases mass movement events during snow melt. To understand and quantify the temporal and spatial influence of climate and tectonics on the evolution of mountain belts and the fluvial systems within is of a major importance for human existence in this challenging environment. To target the timing and possible causes for fluctuations in sediment supply, I investigated a flight of fluvial terraces along the main trunk. The incision into the investigated terraces started at Holocene times ~ 3 ka ago and was accompanied by high incision rates of 4 – 29 mm/yr. The paleodenudation rates associated with the terraces range between 1.75 ± 0.41 mm/yr and 2.01 ± 0.36 mm/yr. The modern denudation rates cover the same magnitude (1.28 ± 0.16 – 1.94 ± 0.26 mm/yr) along the main trunk. The investigation of the tributaries yielded the greatest variation in modern denudation rates in the western Tian Shan tributaries (0.18 ± 0.02 mm/yr to 2.05 ± 0.27 mm/yr). The Alai Valley displays an intermediate signal of 1.14 ± 0.14 mm/yr and the northern Pamir tributaries display rates (1.78 ± 0.23 mm/yr and 1.63 ± 0.21 mm/yr) at the higher end of the spectrum. Additionally 26Al/10Be ratios were used to test, whenever the tributaries are prone to store or mix fresh sediment with shielded material. The results indicate no immediate storage or mixing (26Al/10Be ratios: 6.0 ± 1.0 to 7.6 ± 1.2), except for one western Tian Shan catchment (26Al/10Be ratio: 5.2 ± 0.5)

IntroductionOral diseases can be prevented or improved with regular dental visits. Our objective was to assess and compare national estimates on self-reported oral health conditions and dental visits among pregnant women and nonpregnant women of childbearing age by using data from the National Health and Nutrition Examination Survey (NHANES).MethodsWe analyzed self-reported oral health information on 897 pregnant women and 3,971 nonpregnant women of childbearing age (15\u201344 years) from NHANES 1999\u20132004. We used \u3c72 and 2-sample t tests to assess statistical differences between groups stratified by age, race/ethnicity, poverty, and education. We applied the Bonferroni adjustment for multiple comparisons.ResultsOur data show significant differences in self-reported oral health conditions and dental visits among women, regardless of pregnancy status, when stratified by selected sociodemographic characteristics. Significant differences were also found in self-reported oral health conditions and dental visits between pregnant and nonpregnant women, especially among young women, women from minority race/ethnicity groups, and women with less than high school education.ConclusionWe found disparities in self-reported oral health conditions and use of dental services among women regardless of pregnancy status. Results highlight the need to improve dental service use among US women of childbearing age, especially young pregnant women, those who are non-Hispanic black or Mexican American, and those with low family income or low education level. Prenatal visits could be used as an opportunity to encourage pregnant women to seek preventive dental care during pregnancy.2014738

Implementation of a nonequilibrium condensation model in RELAP4/MOD7

RALAp, which is used to simulate the thermal hydraulic behavior of light water reactors subjected to various LOCA transients, is based on the assumption of thermodynamic equilibrium between liquid and vapor within fluid volumes. This assumption, while being appropriate for much of a LOCA transient, is not adequate during the ECC accumulator injection phase as determined by comparisons of code calculations with experimental data. To overcome this limitation, a general model to simulate the nonequilibrium phenomena associated with the mixing of subcooled water with saturated steam has been developed and is operational on preliminary versions of RELAP4/MOD7

The 1973 Ethiopian-Rift geodimeter survey

Remeasurement of the Adama, Lake Langana, and Arba Minch (Lake Margherita) geodimeter networks in 1973 has enabled Mohr's interpretation concerning possible surface ground deformation in the Ethiopian rift to be considerably developed. Extension appears to have occurred across the Mojjo-Adama horst at a rate of about 1 cm yr/1. The opposing rims of the Adama graben have not moved significantly relative to one another (between 1969 and 1973), but stations on the sliced graben floor show possible movement with a large rift-trend component. In the Wolenchiti quadrilateral, significant movement of station RABBIT is confirmed, but the radical change of vector (that of 1970-1971 to that of 1971-1973) casts doubt on a tectonic cause and seems to indicate that stations on steep hillslopes are liable to be unstable. South of the quadrilateral and east of the Adama graben, alternating rift-trend zones of extension and shortening appear to coexist. In the Lake Langana network, significant movements of the order of 0.5 cm yr/1 are directed perpendicular to the rift floor faulting
