This study introduces a Vorticity Index (VI) and an Imminent Vortex Separation Condition (IVSC), which are considered valuable indicators to quantify the vorticity impact on vertical axis wind turbines (VAWTs) operation. The VI IVSC specifically applied H-Darrieus turbine (VAWT). Findings show that these two parameters display direct relationship with aerodynamic forces govern performance of th...

Abstract Hericium is a well-known genus that comprises edible and medicinal mushrooms with fleshy, distinctive white spines hang from tough, unbranched clump, grows on dying or dead wood. In preparation for the artificial cultivation of these in Thailand, an optimization mycelial growth different agar culture media, various conditions (including temperature, pH, cereal grains, agricultural wast...

The influence of the wing root junction on laminar separation bubble forming suction surface a semispan NACA 0018 cantilevered from wind tunnel test section wall is studied using flow visualisations, particle image velocimetry and pressure measurements at chord Reynolds number 125 000 an angle attack 6 $^\circ$ . boundary layer upstream turbulent, spanwise extends well beyond thickness.

In recent years, there has been an increased interest in the old NACA four-digit series when designing wind turbines or small aircraft. One of airfoils frequently used for this purpose is 0018 profile. However, since 1933, over 70 almost no new experimental studies profile have carried out to investigate its performance regime and medium Reynolds numbers as well various turbulence parameters. T...

This paper reports a miniaturized resonant Lorentz-force magnetometer that exploits blue-sideband actuation to attain better sensitivity and resolution. The consists of double-ended tuning fork (DETF) resonator with cavity slots optimize thermoelastic dissipation, as well generator structure transduce the magnetic force axial resonator. proposed device demonstrates 5.5 mV/nN, noise floor 1.25 <...

We have performed detailed high-resolution spectroscopic analysis on seven metal-poor stars (BD+75 348, BD+09 3019, HD238020, HE0319-0215, HE0507-1653, HE0930-0018, HE1023-1504) and derived their atmospheric parameters T$_{eff}$, log$g$, [Fe/H], mictroturbulent velocity ($\xi$). The metallicity range is found to be -2.57$<$[Fe/H]$<$-0.42. elemental abundances of 17 light elements 12 heavy are e...

This study focuses upon a new permeable topology design concept as an alternative to porous metal foams, for turbulent boundary layer trailing-edge (TBL-TE) noise attenuation. The present has unconventional characteristics with respect the foams: combination of low flow resistivity r and high form drag coefficient C. are realized by Kevlar-covered 3D-printed perforated structure. An experimenta...

Pseudobulbar affect (PBA) is a dysfunction of emotional expression characterized by involuntary outbursts of crying or laughing disproportionate or unrelated to mood, occurring in patients with various underlying neurologic disorders. This review describes the clinical data supporting dextromethorphan (DM) hydrobromide combined with quinidine sulfate (Q) as treatment of PBA and briefly surveys ...
