Ion tracks formed in amorphous Ge by swift heavy-ion irradiation have been identified with experiment and modeling to yield unambiguous evidence of tracks in an amorphous semiconductor. Their underdense core and overdense shell result from quenched-in radially outward material flow. Following a solid-to-liquid phase transformation, the volume contraction necessary to accommodate the high-densit...

the genus ebola virus first was recognized in 1976, when two outbreaks occurred in zaire and sudan. ebola virus disease (evd) is a highly contagious disease that can affect both human and nonhuman primates: zaire ebolavirus (zebov), sudan ebolavirus (sebov), côte d’ivoire ebolavirus (cebov), bundibugyo ebolavirus (bebov) and reston ebolavirus (rebov) are five members of the filoviridae family t...

background: underlying diseases and aggressive procedures, such as different types of surgery and care, for patients with critical conditions in intensive care units (icu) may be associated with physiological disorders. objectives: this study intended to determine the effect of therapeutic touch on physiological variables of patients undergoing mechanical ventilation in icu. methods: this rando...

background: for effective treatment of organophosphate (op) poisoning, development of a standardized protocol with flexible dose regimen for atropine and pralidoxime is an essential step. in this study, we aimed to assess the protocol devised in our setting; bach mai hospital poison treatment center, for treatment of op poisoning that included a higher dose regimen of pralidoxime (2pam). method...

Interface modification for control of ultrafast magnetic properties using low-dose focused ion beam irradiation is demonstrated for bilayers of two technologically important materials: Ni81Fe19 and Pt. Magnetization dynamics were studied using an all-optical time-resolved magneto-optical Kerr microscopy method. Magnetization relaxation, precession, damping and the spatial coherence of magnetiza...

Ion microbeams are important tools in radiobiological research. Still, the worldwide number of ion microbeam facilities where biological experiments can be performed is limited. Even fewer facilities combine ion microirradiation with live-cell imaging to allow microscopic observation of cellular response reactions starting very fast after irradiation and continuing for many hours. At SNAKE, the...

We studied electrostatic charging of ice films induced by the impact of 1−200-keV Ar+ ions and their subsequent discharging postirradiation. We derived the positive surface electrostatic potential from the kinetic energy of sputtered molecular ions and with a Kelvin probe. Measurements were performed as a function of film thickness, temperature, and ion energy. Charging requires that the projec...

We have studied the compaction of vapor-deposited amorphous solid water by energetic ions at 40 K. The porosity was characterized by ultraviolet-visible spectroscopy, infrared spectroscopy, and methane adsorption/desorption. These three techniques provide different and complementary views of the structural changes in ice resulting from irradiation. We find that the decrease in internal surface ...

UNLABELLED The purpose of this study was to determine the orogastric transit time of standard 131I capsules and the incidence of transit delay. METHODS We studied 58 consecutive subjects receiving outpatient diagnostic and therapeutic 131I dosages. A standard ion chamber survey meter, placed over the left upper quadrant of the abdomen, monitored orogastric transit. Each subject had ample wate...
