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...

1. Bronchodilatation was produced in eight normal subjects by inhalation, on separate occasions, of the atropine-like drug ipratropium bromide (0.16 mg by pressurized inhaler; 1 mg nebulized) and the beta 2-sympathomimetic salbutamol (0.8 mg by pressurized inhaler; 5 mg nebulized). 2. Mean specific airways conductance (sGaw) increased from a mean value of 0.185 +/- SE 0.002 to 0.292 +/- 0.023 s...

The paper presents new, transient simulation results of condensing steam in the event of emergency core cooling where water is injected into the cold leg during a postulated loss-of-coolant-accident (LOCA) of a pressurized water reactor (PWR), a phenomenon known as Pressurized Thermal Shock (PTS). The model is first validated for the Lim et al. (1984) experiment involving a smooth to wavy turbu...

Some hydraulic applications are characterized by systems originally flowing in free-surface conditions that subsequently undergo flow regime transition into pressurized flow during rapid filling events. Currently, models simulating these flow regime transitions are classified by approaches that either track the location of the pressurized front or use the Preissmann slot concept. While Preissma...

Pressurized aerosols of sympathomimetic drugs are widely used in the treatment of bronchial asthma. The efficacy of this form of treatment is diminished in a number of patients by difficulties in coordination between the aerosol actuation and the inhalation. In order to improve the intrapulmonary deposition of terbutaline, an extension tube has been adapted to the regular pressurized aerosol de...

Each year there are approximately 76 million foodborne illnesses and fresh produce is the second most common vehicle for such illnesses. Small fruits have been implicated in several outbreaks although none have been bacterial. Prior to market small fruits are not washed or treated in any manner so as to extend their shelf life. Washing alone is not a viable option and the use of novel technolog...

During recent years, foundry industry has witnessed an increasing awareness about the importance of the filling stage for the production of metallurgically sound and dimensionally stable castings. The metallurgical soundness of a casting is strongly influenced by the way the liquid metal flows through various parts of the gating system and fills the mould cavity. Owing to the importance of fill...

The mechanisms of flow-induced vascular remodeling are poorly understood, especially in the coronary microcirculation. We hypothesized that application of flow in small coronary arteries in organoid culture would cause a nitric oxide (NO)-mediated dilation and inhibit inward remodeling. We developed an organoid culture setup to drive a flow through cannulated arterioles at constant luminal pres...

The object of this paper is to study the effects of lubricant film flow, pressurized and sheared between two parallel rough surfaces in sliding motion. The influence of microscopic surface roughness on lubricant film flow macroscopic behavior is described through five nondimensional parameters called flow factors. These macroscopic transport parameters are related to the local geometry of apert...
