Numerical Simulations of Spread Characteristics of Toxic Cyanide in the Danjiangkou Reservoir in China Under the Effects of Dam Cooperation

Many accidents of releasing toxic pollutants into surface water happen each year in the world. It is believed that dam cooperation can affect flow field in reservoir and then can be applied to avoiding and reducing spread speed of toxic pollutants to drinking water intake mouth. However, few studies investigated the effects of dam cooperation on the spread characteristics of toxic pollutants in reservoir, especially the source reservoir for water diversion with more than one dam. The Danjiangkou Reservoir is the source reservoir of the China’ South-to-North Water Diversion Middle Route Project. The human activities are active within this reservoir basin and cyanide-releasing accident once happened in upstream inflow. In order to simulate the spread characteristics of cyanide in the reservoir in the condition of dam cooperation, a three-dimensional water quality model based on the Environmental Fluid Dynamics Code (EFDC) has been built and put into practice. -

Based on two long-term, hourly (10:30–11:30 and 13:10–14:10) meteorological over-lake observations and data from Shenxian meteorological station, nearby Dongping Lake, the Penman-Monteith equation and reference evaporation ratio algorithm were used to calculate lake evaporation in Dongping Lake, China, from 2003 to 2010. The variation trend of evaporation of Dongping Lake was analyzed, and the influences that caused changes in lake evaporation were also discussed. The results show that (1) the total annual evaporation in Dongping Lake increased -

Bell Astronomy Program, University of Maryland Received 1979 December 28; accepted 1980 February 26 ABSTRACT Low-resolution CTIO SIT vidicon spectra of seven upper-main-sequence stars in 47 Tucanae (NGC 104) reveal differences in CN X3883 (0, 0) band strengths. Spectrum synthesis calculations suggest that the star-to-star nitrogen abundances differ by factors of ^5, i.e., by amounts com- parable to those required to explain observations of highly evolved stars in the same cluster. If a primordial origin of the variations is to be rejected, our observations require identification of a mixing mechanism or other process capable of affecting the main-sequence atmospheric abundances of CNO group elements independently of heavier ones.

Philip M. Fearnside(1) National Institute for Research in the Amazon (INPA), Manaus, Brazil Summary. -- China's plans for the Three Gorges Dam on the Yangzi River are a focus of controversy both inside and outside of China. The dam is one of the "Fatal Five" World Bank projects criticized by environmental groups in the United States. The dam entails strategic, social and cultural costs that go far beyond its substantial monetary price. Strategic vulnerability is a major concern. The consequences would be catastrophic should the dam fail as a result of warfare, earthquakes, or other causes. Resettlement of population displaced by the reservoir, especially farmers, presents a formidable obstacle in the mountainous and already-crowded land around the reservoir site. Resettlement could affect minority groups if population is moved to border areas. The reservoir would sacrifice cultural landmarks holding great significance for many Chinese. Erosion and reservoir siltation may impede navigation within a few years, and in the longer term will reduce storage volume, thereby reducing power generation and flood control effectiveness. -
U Antliae — a Dying Carbon Star
THE BIGGEST, BADDEST, COOLEST STARS ASP Conference Series, Vol. 412, c 2009 Donald G. Luttermoser, Beverly J. Smith, and Robert E. Stencel, eds. U Antliae — A Dying Carbon Star William P. Bidelman,1 Charles R. Cowley,2 and Donald G. Luttermoser3 Abstract. U Antliae is one of the brightest carbon stars in the southern sky. It is classified as an N0 carbon star and an Lb irregular variable. This star has a very unique spectrum and is thought to be in a transition stage from an asymptotic giant branch star to a planetary nebula. This paper discusses possi- ble atomic and molecular line identifications for features seen in high-dispersion spectra of this star at wavelengths from 4975 A˚ through 8780 A.˚ 1. Introduction U Antliae (U Ant = HR 4153 = HD 91793) is classified as an N0 carbon star with a visual magnitude of 5.38 and B−V of +2.88 (Hoffleit 1982). It also is classified as an Lb irregular variable with small scale light variations. Scattered light optical images for U Ant have been made and these observations are consistent the existence of a geometrically thin (∼3 arcsec) spherically symmetric shell of radius ∼43 arcsec. The size of this shell agrees very well with that of the detached shell seen in CO radio line emission. These observations also show the presence of at least one, possibly two, shells inside the 43 arcsec shell (Gonz´alez Delgado et al. 2001). In this paper, absorption lines in the optical spectrum of U Ant are tentatively identified for this bright cool carbon star.
