    Development of Biological Aerated Filters: A Review (1999)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 13 (1999), S. 0 
    Details
    ISSN: 1747-6593

    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Biological aerated filters are wastewater-treatment systems which contain support media for the development of a biofilm and provide oxygen at the base of the reactor for aerobic microbial processes. The origins of this type of filter date back to the early 1900s, and modern designs can provide a high level of treatment in small reactor ‘footprints’.This paper provides a review of the technology and development of biological aerated filters and submerged aerated filter systems.

    Effects of Plastic Support Media on the Diffusion of Air in a Submerged Aerated Filter (1998)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 12 (1998), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: The established procedures for quantifying the aeration capacity of diffusers used in submerged aerated filter wastewater-treatment systems do not consider the effects of support media; this may lead to ineffective design and sizing of diffused-air systems. The study was carried out to determine the factors affecting aeration in a submerged aerated filter containing high-voidage random-packed plastic media. Tests were conducted in a full-scale model reactor with and without support media.

    Notes: [Auszug] Quantum bits (qubits) are the fundamental building blocks of quantum information processors, such as quantum computers. A qubit comprises a pair of well characterized quantum states that can in principle be manipulated quickly compared to the time it takes them to decohere by coupling to their ...

    Effects of Pulverized Fuel Ash on the Moisture Characteristics of Soils (1967)
    [s.l.] : Nature Publishing Group

    Details
    ISSN: 1476-4687

    Notes: [Auszug] The largest addition of ash significantly increased the AWC and there were small but non-significant increases with the lower rates of application (Table 1). This effect resulted from the progressive increase in the moisture retained at the upper limit of available water with increasing quantities ...

    Terahertz-frequency electronic coupling in vertically coupled quantum dots (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 77 (2000), S. 4356-4358 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We have studied terahertz absorption of samples containing two layers of self-aligned, self-assembled InAs quantum dots separated by a thin GaAs barrier. The vertically coupled dots were charged with electrons by applying a voltage bias between a metal gate and a doped layer beneath the dots. For a positive gate bias corresponding to flatband conditions, an absorption peak was observed near 10 meV (2.4 THz). The absorption is attributed to the inhomogeneously broadened transition between the quantum mechanically split levels (bonding and antibonding states) in the vertically coupled quantum dots. © 2000 American Institute of Physics.

    Saturation of THz-frequency intraband absorption in InAs/GaAs quantum dot molecules (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 77 (2000), S. 510-512 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: We have investigated the far-infrared absorption in InAs/GaAs quantum dot molecules. The quantum dot molecules consist of two vertically coupled InAs self-assembled quantum dots separated by a GaAs barrier. The electronic coupling between the dot states results in an intraband absorption at THz frequencies. We show that this absorption can be bleached under high excitation intensity delivered by a free-electron laser. The saturation intensity is found to be on the order of 1 W cm−2. The electron relaxation time T1 is estimated from the saturation intensity. A lower limit for T1 of the order of 30 ps is deduced. © 2000 American Institute of Physics.

    Time-resolved photoresponse of a gallium-doped germanium photoconductor using a variable pulse-width terahertz source (2000)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 76 (2000), S. 262-264 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: Picosecond to nanosecond-wide terahertz pulses are used to study the fast photoresponse of a gallium-doped germanium (Ge:Ga) photoconductor operating at 4.2 K. A recombination time of about 2 ns is observed in the time-resolved photoresponse. Laser-activated semiconductor reflection switches are used to "slice" the variable-width terahertz pulses from the quasicontinuous-wave output of a free-electron laser. © 2000 American Institute of Physics.

    Notes: This paper describes the performance of a small packaged plant serving about 70 people and incorporating submerged aerated filters. The diurnal variation was typical of a small sewage-treatment works, and the final effluent was well stabilised with average BOD and amm.-N concentrations of 12 mg/l and 3.8 mg/l respectively.

    Constructed Wetlands for the Treatment of Runoff from the Newbury Bypass (2001)
    Oxford, UK : Blackwell Publishing Ltd
    Water and environment journal 15 (2001), S. 0 
    Details
    ISSN: 1747-6593
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: The A34 Newbury bypass crosses sensitive watercourses and incorporates runoff-control systems. The series of treatment stages of each system comprises an oil interceptor, silt trap, grassy slope and constructed wetland. In December 1998, a monitoring programme was initiated for one of the systems to evaluate the removal and behaviour of pollutants, and this paper presents the initial results. Future work will examine the mechanisms involved in metal removal and the fate of other pollutants.

    Use of DSC as a quality control tool (1989)
    Brookfield, Conn. : Wiley-Blackwell
    Journal of Vinyl and Additive Technology 11 (1989), S. 166-170 
    Details
    ISSN: 0193-7197
    Keywords: Chemistry ; Chemical Engineering

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A differential scanning calorimeter (DSC) has been found to be a very useful quality control tool for a manufacturer of rigid PVC products. It is particularly good at measuring the consistency of lubricants such as paraffin waxes, and ethylene bis-stearamide. Test results are presented which clearly show the difference between two paraffin waxes, both of which were considered identical from normal wax specifications, but which performed differently in production equipment. Also presented are the statistics used to draft raw material specifications which include DSC measurements.
