Direct measurements of the abundance of argon in the lunar atmosphere were made in 1973 by instruments placed on the Moon during the Apollo 17 mission, but the total daytime abundance is unknown due to instrument saturation effects; thus, until we are able to return to the Moon for improved direct measurements, we must use remote sensing to establish the daytime abundance. In this paper, we pre...

introduction cold plasma is a self-sterilized, painless, and non-contact method in surgeries. these properties allow it to be applied to the living tissues and heat-sensitive parts. the aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...

In order to introduce carboxylic acid groups at the surface of poly (ethylene) ( P E ) films, an attempt was made to covalently link a preadsorbed layer of poly (acrylic acid) ( PAAc) on a P E film by an argon or tetrafluoromethane (CF,) plasma treatment. Surface analysis was performed by XPS (X-ray photoelectron spectroscopy) and water contact angle measurements. I t was shown that by treatmen...

The development of a handheld single and triple chamber atmospheric pressure coaxial dielectric barrier discharge driven by Flyback circuitry for helium and argon discharges is described. The Flyback uses external metal-oxide-semiconductor field-effect transistor power switching technology and the transformer operates in the continuous current mode to convert a continuous dc power of 10-33 W to...

The addition of N to a millisecond-pulsed glow discharge (PGD) allows diagnostic measurements of the PGD but 2 is found to drastically influence the transient signals arising from the argon and sputtered analyte atoms. Penning excitation between metastable argon atoms and ground state nitrogen molecules and charge transfer between argon ions and the added nitrogen reduce the degree of ionizatio...

Argon beam photocoagulation has gained popularity as an adjuvant therapy for the treatment of giant cell tumors of bone and other stage 2 or 3 benign-aggressive bone tumors. Although argon beam photocoagulation has been considered a safe and reasonable adjuvant treatment with acceptable recurrence rates, it has never been directly compared with the commonly described phenol as adjuvant. The pur...

BACKGROUND Following kidney transplantation, ischemia-reperfusion injury contributes to adverse outcomes. The purpose of this study was to determine whether a cold-storage solution saturated with noble gas (xenon or argon) could limit ischemia-reperfusion injury following cold ischemia. METHODS Sixty Wistar rats were randomly allocated to 4 experimental groups. Kidneys were harvested and then...
