Aims: Intracardiac echocardiography (ICE) is a relatively young technique used during complex electrophysiology proce-dures, such as atrial fibrillation (AF) ablation. The aim of this study was to assess whether the use ICE modifies radia-tion exposure at beginning learning curve in AF Materials and methods: In retrospective study, 52 patients, which catheter ablation for paroxysmal or persiste...

Murine leukemic lymphoblasts L5178Y-R (LY-R) undergo con version into their L5178Y-S (LY-S) variant as a result of pro longed (5 months to 4 years) cultivation in vitro. LY-R cells are highly tumorigenic in DBA/2 mice; resistant to X-rays [D0 (mean lethal dose [reciprocal of the slope of the linear portion of dosesurvival curve]) = 0.91 grays]; and sensitive to ultraviolet radia tion (D0 = 0.7 ...

Three-dimensional large-eddy simulations of a smoke cloud beneath a strong inversion are used to investigate how grid resolution aaects simulated entrainment rate. These simulations are generalizations of a 1995 GCSS (GEWEX Cloud System Studies) smoke cloud model intercomparison (MacVean et al. 1997). Radiative cooling at the top of the smoke cloud induces convection in the smoke cloud in a man...

Centralnym punktem niniejszego artykułu jest analiza jednej z rozmów przeprowadzonych na antenie Polskiego Radia 24 w ramach cyklu pod tytułem „Wojna cywilizacji”. Rozmówcy poświęcili ją przedstawieniu tezy (dla niektórych oczywistej, a dla innych absurdalnej), zgodnie którą przez świat przetacza się rewolucja polityczno-obyczajowa. Podstawowy cel rozmówców był jednoznaczny: powiedzieć słuchacz...

We have used irradiation to induce marker chromosome formation in a metastasizing murine tumor with a stable karyotype. The induced recombinant chromosomes then served to determine whether métastases were of clonal or multicellular origin. Cumulative data were obtained from four series of experiments on spontaneous métastasesoriginating from tumors grown from irradiated cells; 20 of these mé...

New NLO b → X s γ calculations have become available using resummed radia-tive corrections. Using these calculations we perform a global fit of the supergravity inspired constrained minimal supersymmetric model. We find that the resummed calculations show similar constraints as the LO calculations, namely that only with a relatively heavy supersymmetric mass spectrum of O(1 TeV) the b−τ Yukawa ...
