A stable L-form of Streptococcus faecalis (T(53)) was transferred in media containing decreasing concentrations of sucrose until it grew in medium without added osmotic stabilizer. This L-form (designated T(53I)) was compared with T(53) from which it was derived. The survival of these two L-forms suspended at different osmolalities showed that maximal survival for T(53I) was 350 to 400 milliosm...

In situ band gap mapping of the V2O5(001) crystal surface revealed a reversible metal-to-insulator transition at 350-400 K, which occurs inhomogeneously across the surface and expands preferentially in the direction of the vanadyl (V=O) double rows. Supported by density functional theory and Monte Carlo simulations, the results are rationalized on the basis of the anisotropic growth of vanadyl-...

We present recent near-infrared detections of circumstellar disks around the two old PMS Herbig stars HD141569 and HD100546 obtained with the HST/NICMOS2 camera. They reveal extended structures larger than 350–400 AU in radius. While the HD100546 disk appears as a continuous disk down to 40AU, the HD141569 environment seems more complex, splitted at least into two dust populations. As a convinc...

In this study, microalloyed steels were joined by using the submerged arc welding method at different welding currents of 350 A, 400 A and 450 A. The effects of selected welding parameters on the microstructure and mechanical properties of welded materials were investigated. Tensile tests and microhardness measurements were performed. Microstructural changes have been identified in the welding ...

The taxonomy and distribution of the five species of Hypolycaena in Maluku are discussed and new locality records given. Corrections are made to the published taxonomy and distribution of Hypolycaena phorbas (Fabricius, 1793). This clarification enables a better understanding of the biogeography of the genus. Hypolycaena asahi Okubo, 2007, was originally described from a single female from Ambo...

Recent neuroimaging evidence suggests that visual inputs arising beyond the fovea can be 'fed back' to foveal visual cortex to construct a new retinotopic representation. However, whether these representations are critical for extra-foveal perception remains unclear. Using transcranial magnetic stimulation we found that relatively late (350-400 msec) disruption of foveal retinotopic cortex impa...

A two-wavelength laser-induced fluorescence technique is described for detecting and classifying biological aerosols. Single aerosols, smaller than 10 mm, are interrogated with 266 nm and 355 nm laser pulses separated in time by 400 ns. Fluorescence signals excited by these pulses are detected in three broad spectral bands centered at 350 nm, 450 nm and 550 nm. The results indicate that bacteri...

The solubility of cupric and cuprous oxides was measured in water over the range 25 to 350 °C in the presence of various chemical agents (NaOH, NH3, B(OH)3, H3PO4, (OHCH2)3CNH2, (OHCH2)3CN(OHCH2CH3)2, HF3CSO3, HNO3 and mixtures thereof), and in steam to 400 °C as a function of pressure. Large discrepancies exist between the various experimental studies, especially at high temperatures for cupro...
