PURPOSE To evaluate in a retrospective study the long-term usefulness of red 647 nm krypton and 670 nm diode laser for transscleral contact cyclophotocoagulation (CPC) in the treatment of therapy-resistant inflammatory glaucoma. METHODS The authors treated 48 eyes of 38 consecutive patients (mean age 36.8 years, range 6-81 years) with therapy-resistant inflammatory glaucoma secondary to chron...

The manuscript reports a study of Kr ion implantation in a Zn target in the 10-50 keV energy range at different source parameters, which combines experimental data and simulation with the SRIM package. The implanted thickness for the 45 keV was found to be 10 μm. The ion penetration depths for different films at different energies (10-50 keV) were calculated using SRIM computer program and foun...

We present an analysis of high resolution HST Space Telescope Imaging Spectrograph (STIS) observations of Kr I λ1236 absorption in seven sight lines that probe a variety of interstellar environments. In combination with krypton and hydrogen column densities derived from current and archival STIS and FarUltraviolet Spectroscopic Explorer data, the number of sight lines with reliable Kr/H ISM abu...

2014 We present simultaneous measurements of adsorption isotherms and dielectric isotherms for krypton on lamellar halides. The comparison between the two isotherms shows that dielectric method is well adapted to characterize the multilayer formation. The evolution of dielectric properties from a two-dimensional system towards the bulk is also obtained. J. Physique 42 (1981) 559-564 AVRIL 1981,

The NA48 collaboration is preparing a new experiment at CERN aiming to study CP violation in the K K0 system with an accuracy of 2 10 4 in the parameter Re( = ). Decays into two 's will be recorded by a quasi-homogeneous liquid krypton calorimeter. A liquid krypton calorimeter has been chosen to combine good energy, position and time resolution with precise charge calibration and long-term stab...

Adsorption of para-hydrogen on the surface of graphite pre-plated with a single atomic layer of krypton, is studied theoretically by means of path integral ground state Monte Carlo simulations. We compute energetics and density profiles of para-hydrogen, and determine the structure of the adsorbed film for various coverages. Results show that there are two thermodynamically stable monolayer pha...

For the first time, magnetic resonance imaging (MRI) with hyperpolarized (hp) krypton-83 (83Kr) has become available. The relaxation of the nuclear spin of 83Kr atoms (I = 9/2) is driven by quadrupolar interactions during brief adsorption periods on surrounding material interfaces. Experiments in model systems reveal that the longitudinal relaxation of hp 83Kr gas strongly depends on the chemic...

In the following sections we report the results obtained studying the role of threebody interatomic potentials on noble gas coexisting phases. Section 3.1 gives details of the Gibbs ensemble simulations for vapour-liquid coexisting phases of argon, krypton and xenon as pure fluids and of an argon-krypton mixture. In section 3.2 we report the analytic expression of an effective potential which w...

ANUMBER of methods have been developed for detecting left-to-right shunts during cardiac catheterization of which the most frequently employed is determining the difference in oxygen saturations. This method has limited application in the presence of small shunts, however, since the minimal changes are often within the error of this method.' Therefore, other more sensitive technics have been em...

The dynamics of the noble-gas liquids underlies that of all liquids making them an important prototypical model system. Using optical Kerr-effect spectroscopy we show that for argon, krypton, and xenon, both the librational and diffusional contributions to the spectrum are surprisingly complex. The diffusional relaxation appears as a stretched-exponential, such as widely found in studies of str...
