Digital mucous cysts are common tumours of the distal interphalangeal joint, causing pain, cosmetic disfigurement and nail deformities. This study describes six patients suffering from digital mucous cysts, some of which recurred after surgery. Carbon dioxide laser vaporization was performed under local anaesthesia, resulting in complete remission in four out of six patients. In two patients, t...

The main goal of the work is to investigate the behavior of a geothermal reservoir containing salty water when its physical parameters exceed the critical values, i.e. when the vaporization process cannot be described by the asymptotic self-similarity solution. We consider a low-permeability rock, where salty water vaporizes at a sharp front, because of fluid extraction at constant pressure. If...

The exact amount of vaporization losses and melt layer thickness resulting from a plasma disruption are very important to fusion reactor design and lifetime. Experiments using ion or electron beams to simulate the disruption effects have different environments than the actual disruption conditions in fusion reactors. A model has been developed to accurately simulate the beam-target interactions...

Recent efforts using perfluorocarbon (PFC) nanoparticles in conjunction with acoustic droplet vaporization has introduced the possibility of expanding the diagnostic and therapeutic capability of ultrasound contrast agents to beyond the vascular space. Our laboratories have developed phase-change nanoparticles (PCNs) from the highly volatile PFCs decafluorobutane (DFB, bp =-2 °C) and octafluoro...

The relationship between the Randic , Wiener, Hosoya , Balaban, Schultz indices, Harary numbers andDistance matrix to enthalpies of formation (Airf), heat capacity, (Cp) , enthalpies of combustion (AH °c ),enthalpy of vaporization (AH °vap) and normal boiling points (bpK)of C2 C10 normal alkanes isrepresented

A method for measuring the vapor pressures of a wide range of materials using a conventional thermobalance and standard sample holders is described. The equipment is calibrated using pure reference materials of known vapor pressure and exploiting the relationship between volatilization rate and vapor pressure based on the Langmuir equation for free evaporation. Enthalpies of vaporization and su...

A computational heat and mass transfer model of ceramic precursor solution containing droplets injected into a combustion flame is presented. Upon heat-up and vaporization, the precursor in droplets precipitate and ultimately form the ceramic material. Temperature and solute concentration distributions were computed to estimate the precipitation zones within droplets based on a simple homogeneo...
