Background & Aims of the Study Irradiation with ultraviolet light (UV) is used for the disinfection of bacterial contaminants in the production of potable water. The main objective of the study was to investigate and model Disinfection By-Products (DBPs) formation due to the UV Irradiation of the Tajan River water under different Irradiation conditions. Materials & Methods: &nbs...

PURPOSE We examined corneal surface response to an isolated thermal load. METHODS Cadaveric porcine eyes were pressurized and stabilized for processing and imaging. A carbon dioxide (CO2) laser (1.75 W) delivered a uniform disk of continuous wave thermal radiant energy to the exposed corneal stromal surface without ablation. Thermal load was determined by measuring corneal surface temperature...

OBJECTIVE Peri-implantitis is one of the most common reasons for implant failure. Decontamination of infected implant surfaces can be achieved effectively by laser irradiation; although the associated thermal rise may cause irreversible bone damage and lead to implant loss. Temperature increments of over 10ºC during laser application may suffice for irreversible bone damage. PURPOSE OF STUDY ...

Sic films have been prepared by photochemical vapour deposition using a D lamp from a gas mixture of CH3SiC13+H +Ar on a grapaite plate. The deposition temperature o$ the Sic films of a single phase was lowered by irradiation with a D2 lamp by 50°C as compared to that without irradiation. Furthermore, the deposition rate was increased with irradiation by 1.2-2.8 times as compared to that withou...

In this work an analytical equation of state has been employed to calculate the PVT properties ofternary refrigerant mixtures. The theoretical EoS is that of Ihm, Song and Mason, which is based onstatistical-mechanical perturbation theory, and the two constants are enthalpy of vaporization ΔHvapand molar density ρnb, both at the normal boiling temperature. The following three temperaturedepende...

The effect of microwave irradiation on DNA/DNA hybridization has been studied under controlled power and temperature conditions. It was discovered that microwave irradiation led to the melting of double-stranded deoxyoligonucleotides well below their thermal melting temperature and independent of the length of the deoxyoligonucleotides. These observations indicate a specific interaction of micr...

F-center and colloid particle formation have been studied in synthetic NaCl and natural rock salt crystals with apparatus for making optical absorption measurements during irradiation. Fcenter and colloid formation are functions of temperature, dose, dose rate, strain applied prior to irradiation and numerous other factors. Many of the observed properties are in accord with the Jain-Lidiard the...

Ultrasound in a liquid phase cause mass and heat transfer across the liquid through cavitational processes which act as nanoreactors to generate unstable mechanical equilibrium. The effect of 1 MHz ultrasound on the inactivation of Cryptosporidium parvum was investigated. Continuous irradiation of ultrasound (20 min) increased temperature due to cavitational phenomena. Ultrasound irradiation of...

We present results of a range of experiments of sputtering of water ice together with a guide to the literature. We studied how sputtering depends on the projectile energy and fluence, ice growth temperature, irradiation temperature and external electric fields. We observed luminescence from the decay of H(2p) atoms sputtered by heavy ion impact, but not bulk ice luminescence. Radiolyzed ice do...

The nature and properties of radicals produced by the action of electron and ^-radiation on adamantane have been investigated. Radicals produced by irradiation at 77 °K are stable to around room temperature, while irradiation at the latter temperature yields well resolved spectra of species stable to about 130 °C. The significance of the latter, assigned as the 1-adamantyl radical, in the forma...
