This study was conducted to assess the effectiveness of phytoremediation on a tailing dam located in Shimen County, Hunan Province. Quadrat survey method was employed to investigate and sample the dominant plant species growing on the rehabilitated tailing dam. The fertilities of the soils were assessed, and concentrations of arsenic and other heavy metals in the plant and soil samples were mea...

In November 2001 a new research facility has been proposed by GSI [1]. The proposed facility consists of two superconducting synchrotrons SIS100/200 and three cooler storage rings for radioactive ion and antiproton beams. The new accelerators will use the existing accelerators UNILAC and SIS18 as drivers. SIS100/200 is characterized by a number of demanding technical features. These are especia...

The SLAC electron-positron colliding beam facility and its associated magnetic detector facility are described. General experimental problems in performing photon-photon collision experiments at SPEAR and the proposed experiment of Masek et al. are discussed. -e (Talk presented at the International Colloquium on Photon-Photon Collisions in Electron-Positron Storage Rings, Paris, Sept. 3-4, 1973...

Emerging high-speed networks give rise to a new class of applications in the domain of multimedia. Multimedia applications commonly include the use of video and audio to represent information. Video On-Demand, Tele-Shopping, Teleconferencing, and multimedia games are typical examples of such applications. With the exception of purely conversational applications like Teleconferencing all other m...

Environmental storage conditions, particularly air temperature, relative humidity and air velocity, have a major role in maintaining fruit and vegetable quality during cold storage. The constant low temperature, high relative humidity (RH) and moderate air flow are important to limit perishable quality. Storage temperature controls must be well calibrated to maintain a precise level of control....

The Duke storage ring is a dedicated facility for the UV-VUV FEL operation. The low level computer control system for the Duke storage ring is developed using EPICS. The control hardware employs several different architectures including CAMAC, GPIB, Allen Bradley, and VME. The high level control is implemented in Tcl-Tk scripts running on SPARCstations. TclTk provides the global control capabil...

The results of field studies to study the siltation a reservoir and dynamics their are presented. article presents designs that allow reducing amount sediment entering bowl. structure will contain spillways located perpendicular bed supply channel, elements connecting structures, storage facility, lateral water outlet facility. has mark below bottom channel above maximum level in wall large peb...

We describe the design and implementation of a persistent object storage facility based on a dossier driven approach Objects are characterized by dossiers which describe both their language de ned and extra linguistic properties These dossiers are generated by a C preprocessor in concert with an augmented but completely C compatible class description language The design places very few burdens ...
