Enterovirus (EV) is an RNA virus that has circulated with different serotypes and genotypes worldwide. Enterovirus 71 (EV71) is a major neurotropic virus that causes severe brain stem encephalitis (BE) in infants and young children. The most vulnerable age for fatal infection is 6 to 11 months. This is associated with the coincident decline in maternal antibodies. The current report describes o...

A novel blue-emitting Sr3.5Y6.5O2(PO4)1.5SiO4(4.5) :Eu2+ phosphor was synthesized via a solid-state reaction. Powder X-ray diffraction (XRD) analysis demonstrated that the Sr3.5Y6.5O2(PO4)1.5(SiO4)4.5 host had a hexagonal crystal structure in the space group P6(3) /m and unit cell parameters a = 9.418 Å, c = 6.900 Å. The as-prepared phosphor showed a blue emission and all the main emission peak...

The number of electric vehicles (EVs) and solar photovoltaic panels (PVs) are rapidly increasing in many power grids. An important emerging challenge is managing their less desirable consequences (e.g. grid instability and peak load), particularly urban environments. We present a solution that matches the temporal nature PV generation EV charging. This simple coordination strategy for chargi...

Recently, a cell-culture independent protocol for detection of enteroviruses from clinical specimen was recommended by the WHO for surveillance alongside the previously established protocols. Here, we investigated whether this new protocol will show the same enterovirus diversity landscape as the established cell-culture dependent protocols. Faecal samples were collected from sixty apparently h...

2014 The 0.839 eV luminescence line in GaAs : Cr is generally interpreted as an internal transition in Cr2+ ion (5E-5T2) on gallium site. This interpretation does not agree with E.P.R. and far-infrared absorption results. White has proposed an interpretation as an excitonic recombination on an isoelectronic deep centre. We propose an alternative explanation in which the 0.839 eV line would be a...

Bend magnet beamline 6.3.1 at the Advanced Light Source operates from 200 eV to 2000 eV, primarily used for x-ray absorption fine structure investigations. The beamline optics consist of a compact, entrance-slitless, HettrickUnderwood type variable-line-spacing plane-grating monochromator and refocusing mirrors to provide a 25 μm x 500 μm spot at the focal point in the reflectometer end station...

Extracellular vesicles (EV) in breast milk carry immune relevant proteins and could play an important role in the instruction of the neonatal immune system. To further analyze these EV and to elucidate their function it is important that native populations of EV can be recovered from (stored) breast milk samples in a reproducible fashion. However, the impact of isolation and storage procedures ...
