Results of broadband dielectric spectroscopy (BDS) in Saccharomyces cerevisiae (baker's yeast), in situ as the function of pressure are presented. They show a clear evidence of a threshold to the new pattern of the pressure evolution of the static dielectric permittivity and DC electric conductivity already for Pt  ≈ 200MPa at T = 5 oC and Pt  ≈ 300MPa at T = 25 oC. BDS monitoring versus pressu...

ll is now accepted that inhaled bronchodilator therapy is, whenever possible, to be preferred to oral treatment in the routine management of reversible airflow obstruction [1). However, during the last two decades we have repeatedly been reminded that many patients have great difficulty in using the conventional pressurized metered dose inhaler (MDI) [2-6], today's most frequently prescribed in...

The absolute systemic availability and pulmonary deposition of budesonide inhaled from a pressurized metered-dose inhaler (pMDI) attached to a Nebuhaler spacer was determined in 15 healthy subjects. The study was of an open cross-over design. Each subject randomly received three single doses of budesonide on separate days: 0.5 mg given intravenously and 1.0 mg (0.2 mg x 5) by inhalation from a ...

To investigate alternative mechanisms generating artificial circulation during cardiopulmonary resuscitation (CPR), an electrical model of the circulation was developed. Heart and blood vessels were modeled as resistive-capacitive networks; pressures in the chest, abdomen, and vascular compartments as voltages; blood flow as electric current; blood inertia as inductance; and the cardiac and ven...

OBJECTIVE Assess paranasal sinus distribution of topical solutions following endoscopic sinus surgery (ESS) using various delivery devices. STUDY DESIGN Experimental prospective study. SUBJECTS AND METHODS Ten cadaver sinus systems were irrigated with Gastroview before surgery, after ESS, and after medial maxillectomy. Delivery was via pressurized spray (NasaMist), neti pot (NasaFlo), and s...

This paper presents a computational study of the fluid-structure interaction (FSI) mechanism in pressurized commodity tank cars in railroad application. Within the Lagrangian framework of Abaqus/Explicit, finite element analysis (FEA) is conducted to predict the structural response of tank cars under dynamic impact loading. A three-phase approach is adopted that explicitly models pressurized ga...

Fusion reactors are expected to be safer, more environmentally friendly, and have a lower nuclear proliferation risk, compared with other energy systems. However, it is widely recognized that large amount of radioactive materials will produced by fusion reactor. Therefore, important fully understand the overall radiation risk level wastes (radwaste) existing Studies on treatment radwaste been c...

Stable feeding of biomass powders into reactors represents a technical operational challenge for renewable energy generation. The injection sawdust has been recently published with horizontal pressurized gas injector under several experimental conditions. Valid numerical models based on computational fluid dynamics (CFD) are useful hydrodynamics characterization different equipment scales. In t...
