The literature pertinent to various aspects of drop evaporation on a heated surface is reviewed. Both the laser shadowgraphic and direct photographic methods are employed to study thermal stability and flow structures in evaporating drops in all heating regimes. It is revealed that four flow regions exist in stable and unstable type drops at low liquid-film type vaporization regime. As the surf...

A typical electrothermal vaporization (ETV) using a tantalum was built for low-pressure ICP-AES. The analytical performance of the ETV was tested and compared with that of a PFA pneumatic nebulizer with a double membrane desolvator (DMD). The limits of detection of the ETV were obtained in the range of 3.4 ng to 758 ng for Zn, Cu, Co, Fe, and Mg, while those of the PFA nebulizer were in the ran...

The vaporization wave hypothesis Is discussed and Its merits and defects are examined. The vaporizing model is visualized on thermodynamic grounds as carrying the liquid metal through a continuous succession of states either on or near the liquidus line in the two-phase region. On this line the adiabatic sound speed for wet vapor will limit the rate of propagation of the vaporization front into...

OBJECTIVE In a series of cases of high-grade vaginal intraepithelial neoplasia (VaIN) at our institution, to analyze its clinicopathologic characteristics, diagnostic methodology, and therapeutic results obtained with the use of CO2 laser vaporization. MATERIALS AND METHODS Between January 2003 and December 2009, 28 patients with a diagnosis of high-grade VaIN were treated in our department u...

To investigate the factors that influence treatment satisfaction after high-power potassium-titanyl-phosphate (KTP) laser vaporization of the prostate, we compared the characteristics between patients who were satisfied and those who were not satisfied. In all, 97 patients aged between 53-82 years (median age 67 years) underwent high-power KTP laser vaporization of the prostate for lower urinar...

Activating droplets vaporization has become an attractive strategy for ultrasound imaging and physical therapy due to the significant increase in ultrasound backscatter signals and its ability to physically damage the tumor cells. However, the current two types of transitional droplets named after their activation methods have their respective limitations. To circumvent the limitations of these...

Droplet vaporization models that are currently employed in simulating sprays are based on a quasisteady, low-pressure formulation. These models do not adequately represent many high-pressure effects, such as nonideal gas behavior, solubility of gases into liquid, pressure dependence of gasand liquid-phase thermophysical properties, and transient liquid transport in the droplet interior. In the ...

Samples made of ABS material were produced on devices from three different manufacturers: Stratasys, Velleman, 3Novatica. The quality the printed surface was improved by vaporization with acetone vapours. Roughness measurements performed, which proved improvement after vaporization. structure samples also tested using a computer microtomography. It has been shown that excessive exposure to solv...
