A technique for stator-resistance-based thermal monitoring suitable for low-cost vector controlled three phase induction motor (IM) drive is suggested in this paper. Estimated stator resistance can be used for motor thermal protection, or for compensation of parameter variations in control algorithm. The technique is specifically selected to provide robust temperature estimation while rotor is ...

several methods are available to produce haploid plants. one of the most efficient methods is especially microspore culture. stress as a triggering factor is essential for embryogenesis induction in microspores. in the first experiment, the effect of different thermal stresses including cold treatments and heat stress and the control were evaluated. in the second experiment, the effect of 2,4-d...

The shrimp Rimicaris exoculata swarms around hydrothermal black smoker chimneys at most vent sites along the Mid-Atlantic Ridge. This species maintains close proximity to the hydrothermal fluid, where temperatures can reach 350 degrees C and steep thermal and chemical gradients are expected. We performed in vivo experiments in pressurized aquaria to determine the upper thermal limit [critical t...

pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...

Glass with embedded metal and sulfides (GEMS) is a major component of chondritic porous interplanetary dust particles. Although GEMS one the most primitive components in Solar System, its formation process conditions have not been constrained. We performed condensation experiments gases system Mg-Si-O (MgSiO3 composition) S-free CI composition (Si-Mg-Fe-Na-Al-Ca-Ni-O system) induction thermal p...
