SG 3524 based modified sine-wave inverter driver circuit, a step-up. Modified sine wave inverter is designed to using pic microcontroller and push pull topology. output of control circuit for modified sine wave inverter The ...

A Particle-in-Cell (PIC) code, called Parsek2D, for the simulation of astrophysical and space plasmas is presented. Parsek2D enables simulations with large grid spacing and long time step, by means of implicit time differentiation and parallel computing. An implicit formulation of the PIC algorithm removes the severe numerical stability constraints of explicitly time-differenced PIC. Parallel s...

Pentobarbital (PB) and picrotoxin (PIC) bind to allosterically coupled sites on the GABAA receptor complex but have opposite effects on GABA receptor currents. PB, an anesthetic/anticonvulsant, enhances, and PIC, a convulsant, inhibits GABA receptor currents. PB and PIC also had opposite effects on single main conductance channel GABA receptor currents recorded from excised outside-out patches ...

Transcription consists of a series of highly regulated steps: assembly of the preinitiation complex (PIC) at the promoter, initiation, elongation, and termination. PIC assembly is nucleated by TFIID, a complex composed of the TATA-binding protein (TBP) and a series of TBP-associated factors (TAFs). One component, TAF7, is incorporated in the PIC through its interaction with TFIID but is release...

A constitutively active population of alpha(1D)-adrenoceptors in iliac and proximal, distal, and small mesenteric rat arteries was studied. The increase in resting tone (IRT) that evidences it was observed only in iliac and proximal mesenteric and was inhibited by prazosin (pIC(50) = 9.57), 5-methylurapidil (pIC(50) = 7.61), and BMY 7378 (pIC(50) = 8.77). Chloroethylchlonidine (100 micromol/l) ...

The dendrites of motoneurons are not, as once thought, passive conduits for synaptic inputs. Instead they have voltage-dependent channels that provide the capacity to generate a very strong persistent inward current (PIC). The amplitude of the PIC is proportional to the level of neuromodulatory input from the brainstem, which is mediated primarily by the monoamines serotonin and norepinephrine....
