Pulse nebulization in pneumatic devices.
Aerosols of a physiological salt solution and aqueous solutions of salbutamol, sodium cromoglicate, and dornase alfa were generated in a pneumatic nebulizer and analyzed in a system with controlled humidity of air as a carrier gas. Mass distribution of aerosol particles and yield of generation for pulse nebulization were measured. Pulsation of generation was realized with an attachment maintain...
متن کاملThe GnRH Pulse Generator
The pulsatile secretion of hormones is an efficient way of coding a large variety of chemical messages. The GnRH pulse pattern determines which gonadotropin is released when and at what concentration, prescribing a detailed set of instructions to the gonads that produce changes in the steroid hormone milieu. Although GnRH neurons possess some inherent rhythmicity, they are diffusely situated wi...
متن کاملCompact Nanosecond Pulse Generator
A compact nanosecond pulse generator was designed and tested. The generator has a specially designed unit consisting of an HCEIcap 1000.2 capacitor and a multigap switch. The total inductance of the unit is 20 nH. The modifications made in the design allowed an increase in energy density up to 370 J/l at an electric field strength of 200 kV/mm. The volume of the capacitor active part is 2.3 l. ...
متن کاملPosition Control of a Pulse Width Modulated Pneumatic Systems: an Experimental Comparison
In this study, a new adaptive controller is proposed for position control of pneumatic systems. Difficulties associated with the mathematical model of the system in addition to the instability caused by Pulse Width Modulation (PWM) in the learning-based controllers using gradient descent, motivate the development of a new approach for PWM pneumatics. In this study, two modified Feedback Error L...
متن کاملPulse generator design
The techniques normally used for generating pulses in low-cost monolithic technology (CMOS or BiCMOS) are different from those usually used in hybrid technologies. The latter mainly use edge combination methods generated from SRD diodes via quarter-wave lines or stubs (Jeongwoo Han et al., 2004). In a low-cost context, these techniques are not possible, as they cannot be integrated into the des...
