Zinc and cadmium hexacyanocobaltates(III) were prepared, and their porous networks were explored using 129Xe spectroscopy. The crystal structures of these two compounds are representative of porous hexacyanometallates, cubic (Fm-3m) for cadmium and rhombohedral (R-3c) for zinc. In the cubic structure, the porosity is related to systematic vacancies created from the elemental building block (i.e...

We present a progress report on a program to develop a high–power second harmonic magnicon amplifier at 11.4 GHz for linear accelerator applications. The experiments are being carried out on the NRL Long–Pulse Accelerator Facility using a plasma cathode to create the electron beam. Typical beam parameters are 500–700 kV, 170–250 A, 5.5 mm diameter, with a ~300 nsec voltage flattop. The accelera...

The acid-base balance parameters (ABB) of blood are used in the diagnostics and therapy of acidosis or alkalosis type disorders. Nowadays, some reports on the attempts to use the body cavity fluid for the diagnostics of the ABB disorders have appeared in the human medicine. The study has aimed at comparing the acid-base balance parameters (ABB): pH, pCO2, and HCO3(-) determined in the arterial ...

A 330-pL chromatographic bed was fabricated on a glass substrate as part of an electroosmotically pumped microfluidic system. Two weirs within a sample channel formed a cavity in which octadecylsilane (ODS) coated silica beads (1.5-4 microns diameter) were trapped. ODS beads were mobilized into and out of the cavity using electroosmotic flow through a bead-introduction channel which accessed th...

We investigate the suitability of toroidal microcavities for strong-coupling cavity quantum electrodynamics sQEDd. Numerical modeling of the optical modes demonstrate a significant reduction of the modal volume with respect to the whispering gallery modes of dielectric spheres, while retaining the high-quality factors representative of spherical cavities. The extra degree of freedom of toroid m...

INTRODUCTION Peritoneal loose body(PLB) is usually small, therefore giant Peritoneal loose body(gPLB) with a diameter >5cm has rarely been described in the literatures. We report a case of two gPLB simultaneously found in one patient. PRESENTATION OF CASE A healthy 79-year-old man palpated himself a solid mass with alternating localizations in his peritoneal cavity 6 months ago. It was not th...

The aim of the research is to study the possibilities of ultrasound sonography in children with generalized purulent appendicular peritonitis (GPAP) complicated with intestinal paralysis (IP). This should help to assess motor activity of the intestine, as well as development of pathological process in a peritoneal cavity. 93 patients (children from 2 to 15 years) with appendicular peritonitis w...

PURPOSE The goal of this study was to characterize features of normal and neoplastic oral mucosa using reflectance confocal microscopy. EXPERIMENTAL DESIGN Oral cavity biopsies were acquired from 17 patients at the Head and Neck Clinic of The University of Texas M. D. Anderson Cancer Center who were undergoing surgery for squamous cell carcinoma within the oral cavity. Reflectance confocal im...

Potassium channels enable K(+) ions to move passively across biological membranes. Multiple nanosecond-duration molecular dynamics simulations (total simulation time 5 ns) of a bacterial potassium channel (KcsA) embedded in a phospholipid bilayer reveal motions of ions, water, and protein. Comparison of simulations with and without K(+) ions indicate that the absence of ions destabilizes the st...

The availability of commercial 325 MHz, 2.5 MW klystrons initiated the development of linac resonators which fit to that power level source: this will lead to a significant overall linac cost reduction. This is achieved if individual cavity modules can be rf coupled efficiently. At IAP Frankfurt a coupling cell for CH – cavity modules was designed, which at the same time can house a transverse ...
