In the context of in-hospital care management, need for infusion therapies involves choice appropriate devices. Historically, there is no consensus about preference vascular accesses, although data present in literature would seem to favor peripheral ones due fearful complications and a non-negligible rate bloodstream infections. It also true decision central routes sometimes dictated by patien...

From March 1990 to May 1993,309 patients underwent redo cardiac surgery operation at the Shahid Rajai Heart Hospital in Tehran. Early mortality rates in these patients showed a significant increase in comparison to patients undergoing open heart surgery for the first time. Late mortality (at least one month after surgery) in the patients was slightly increased also but less than early morta...

BACKGROUND The use of antibiotics in the livestock sector is increasing to such an extent that it threatens negative consequences for human health, animal health and the environment. Homeopathy might be an alternative to antibiotics. It has therefore been tested in a randomised placebo-controlled trial to prevent Escherichia coli diarrhoea in neonatal piglets. METHOD On a commercial pig farm ...

Previous work has reported numerical and experimental results pertaining micro-scale laser shock processing, which imparts compressive residual stresses in metallic targets with higher spatial resolution. In this paper, the more detailed physical process of laser-liquid-solid interaction is considered to achieve more accurate simulation results of shock pressure and to provide values for coeffi...

Recently, lateral resolution of photoemission spectroscopy has been rapidly improving by several types of energy-filtered electron emission microscopes (PEEM) or by focused light sources.1–6) On the other hand, laser-based photoemission spectroscopy facilitates femtosecond time-resolution, revealing the dynamics of electrons and atoms on surfaces.7–11) The combination of lateral and temporal re...

This study investigates the influence of the acoustic properties of vowels on 6- and 10-month-old infants' speech preferences. The shape of the contour (bell or monotonic) and the duration (normal or stretched) of vowels were manipulated in words containing the vowels /i/ and /u/, and presented to infants using a two-choice preference procedure. Experiment 1 examined contour shape: infants hear...

A globally-averaged, pulsed inductive plasma model is reproduced and utilized to investigate pre-ionization conditions for a pulsed inductive plasma accelerator. Attention is given to better quantifying the formation and energy conversion/loss processes associated with the pre-ionization stage. Simulations are completed for different power input pulse duration, seed plasma density, and total in...

During the second year of life, infants exhibit a video deficit effect. That is, they learn significantly less from a televised demonstration than they learn from a live demonstration. We predicted that repeated exposure to televised demonstrations would increase imitation from television, thereby reducing the video deficit effect. Independent groups of 6- to 18-month-olds were exposed to live ...
