The two main electrode techniques for fullerenes production; the direct arc technique and the resistive heating of graphite rod were employed in this work. One of the electrodes was resistively heated to high temperature and subjected to arc discharge along its length by the second graphite rod. Fullerenes solid were extracted from carbon soot samples collected from an installed arc discharge s...

To better understand how positive bias and deposition pressure affect the plasma flow properties in chamber during bias-enhanced MPCVD process, a two-dimensional axisymmetric model based on discharge mechanism of pure H2 was constructed. The coupling process between different physical field models electromagnetic field, plasma, temperature reactor is realized. We studied influence voltage varia...

The discharge muffler of the rotary compressor is used to reduce the discharge noise produced by pressure pulsations. In order to obtain the transmission loss of discharge muffler, four microphone experimental devices used to measure the transmission loss of the muffler is established. The device is based on the transfer function method on the assumption that there is only plane wave in the tub...

<p>In this paper we present a novel methodology for time-domain characterization of full anechoic chamber using the finite integral method. This approach is considered fast, accurate and not intensive computer resources. The validation carried out on CST-microwave studio intended antennas measurement applications electromagnetic exposure evaluation cellular network. Low, medium high gain ...

Stormwater runoff is a known pollutant source capable of causing surface water degradation, especially in highly populated areas such as Central Florida. Wet detention ponds manage this stormwater, but most of the ponds do not remove enough nutrients, specifically nitrogen and phosphorus, to meet TMDL regulations. This paper presents the use of a Chamber Upflow Filter and Skimmer (CUFS) filled ...

State = R≥0 ×R≥0 For an abstract state (d, a), we call dist(d, a) = d+ a the energy-adjusted distance. The computational state comprises: • A simple distance d ∈ R≥0 to the base station, like the simple distance of an abstract state. • An energy level e ∈ Energy. • An energy-faithful adjustment f ∈ R≥0 capturing energy deficiencies along the route to the base station. • A table nt containing en...

High current discharge channels are an interesting alternative for the transport of intense ion beams. A sufficiently dense plasma can neutralize both beam-space charge and current and provides a strong focusing magnetic field all the way along the channel. Laser initiated discharge channels were subject to detailed investigations in the past few years at GSI [1, 2]. Recently, stable discharges...

Parkinson disease (PD) is a chronic, progressive and debilitating disease. This study aimed to determine the relationship between the dimensions of Roy Adaptation Model (RAM) and General Health (GH) and Satisfaction with Life (SWL) in PD patients. This was a cross-sectional study. Samples were selected from the PD patients in 2016. The data was gathered by demographic, RAM, GH and SWL Scale que...
