the effect of gibberellic acid (ga3) and benzyladenine (ba) on aloe vera was evaluated at pot cultivation conditions. this study was performed in two factorial test based on complete random plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 and ba at 0, 100, 200 and 400 mg.l-1 levels. the nu...

A new algorithm is proposed for polynomial or rational approximation of the planar offset curve. The best rational Chebyshev approximation could be regarded as a kind of geometric approximation along the fixed direction. Based on this idea, we developed a wholly new offset approximation method by changing the fixed direction to the normal directions. The error vectors follow the direction of no...

We report a 333 MHz femtosecond optical parametric oscillator in which carrier-envelope offset stabilization was implemented by using a versatile locking technique that allowed the idler comb to be tuned continuously over the mid-infrared range from 1.95 to 4.0 μm. A specially designed multi-section, multi-grating, periodically poled KTP crystal provided simultaneously phase-matched parametric ...

Experiments devoted to evaluate the performance of a MEMS thermal flow sensor in measuring gas volumes are described. The sensor is a single-chip platform, including several sensing structures and a low-offset, low-noise readout interface. A recently proposed offset compensation approach is implemented obtaining low temperature drift and excellent long time stability. The sensor is fabricated b...

Plunge milling is a machining process recognized to be efficient for roughing deep workpieces. This due the distribution of cutting forces on tool. Important axial and reduced radial lead more rigidity, eventually productivity. It commonly used in case hard cut materials, like titanium alloys. However, plunge can exhibit problem at end plunging phase, which increase forces. Within this paper, s...

and power efficiency for AJT = 0 which is typical for noncoherent receivers (cf. [3]). Thus, in practice, N has to be optimised with respect to the maximum expected frequency offset Af,,,. This also ensures an acceptable performance for smaller frequency offsets IAfl I Afmax. Optimisation with respect to a mean frequency offset Af,,,, is not recommended since a large performance degradation may...

We use L-band Advanced Land Observation Satellite PALSAR data to infer the distribution of subsurface fault slip during the Tarlay earthquake (Mw 6.8) in eastern Myanmar. We find the total length of surface rupture is approximately 30 km, with nearly 2 m maximum surface offset along the westernmost section of the Nam Ma fault (the Tarlay segment). Finite-fault inversions constrained by Interfer...
