Gravity-feed drilling is the most commonly used method for micro-hole drilling in glass with spark assisted chemical engraving (SACE). This paper proposes a method allowing the systematic characterization of this drilling method. The influences of voltage, ...
The effect of RC attenuation was not correctly taken into account. This led to a misinterpretation of the photocurrent response data that was in Figure 3a on page 17717 and further discussion. Under operating conditions, electrons are accumulated throughou ...
Systematic evaluation of different trickle irrigation design and management scenarios must consider the impact of a particular design on crop response at different soils, climatic conditions, and management options. Anecdotal evidence suggests that differe ...
Catalytic chemical vapour deposition (CCVD) is currently the most promising technique to produce carbon nanotubes (CNTs) on a specific site as well as on a large-scale. Here, we review our recent experimental studies on CNTs grown by CCVD. The yield as wel ...
[1] Nutrient transfer from soils to surface waters is associated with large, hydrologically induced fluctuations. Consequently, stream-based estimation of long-term changes in nutrient leaching is masked by variations of stream discharge. Using high-resolu ...
We realized an experimental setup to study the dynamics of cavitation bubbles inside spherical water drops produced in microgravity (8th Student Parabolic Flight Campaign, European Space Agency ESA). Water volumes of up to 8 ml (25 mm diameter) were expell ...
We have observed the filamentation of optical pulses in carbon disulfide(CS2) using femtosecond time-resolved optical polarigraphy(FTOP)1. A pump-probe setup is used to capture the propagation of a 150 femtosecond laser pulse in CS2. The probe pulse propag ...
This paper presents a first assessment of the hydrometeorological potential of a C-band doppler weather radar recently installed by the Royal Meteorological Institute of Belgium near the town of Wideumont in the southern Ardennes region. An analysis of the ...
Regions of positive slope in the pressure-discharge characteristics are one of the major concerns in design and operation of centrifugal pumps, as they are limiting the admissible operating range to values above the critical discharge. The industrial pump ...
Dielectric barrier discharges (DBDs) are investigated in helium and nitrogen as a function of pressure from 5 to 1000 mbar. Different regimes are observed: glow, Townsend, multi-peak and filamentary, depending on pressure, power and electrode gap. In heliu ...
