Harmfulness of moulding sands with bentonite and lustrous carbon carriers
Metalurgija, 2012 Procedures have been developed to determine the volume, rate and composition (particularly BTEX: benzene, toluene, ethylbenzene and xylenes and PAHs (polycyclic aromatic hydrocarbons)) of gas evolution from moulds and cores prepared with various binders ...

MRI of Neurogenic Human Motor Units Following Poliomyelitis
Muscle &Nerve, EarlyView.ABSTRACT Introduction/Aims Surviving motor units in neurogenic diseases demonstrate collateral reinnervation. Scanning electromyography (EMG) reveals normal motor unit corridor length, but with “silent regions,” suggesting that reinnervation does not result in increased motor unit size but may increase motor unit complexity.

Improve the humidity resistance of sodium silicate sands by ester-microwave composite hardening
Metalurgija, 2014 An easy hardening method of sodium silicate sands, ester-microwave composite hardening, could decrease the sands mould absorbing moisture and the mould materials requirement. And it was performed by hardening the sodium silicate sands with a little ester,

Influence of EDTA Coverage Density on Optical Fiber Sensor for Heavy Metal Ion Detection
Nano Select, EarlyView.This study investigates the influence of chelating agent coverage on the performance of optical fiber sensors for heavy metal ion detection. Ethylenediaminetetraacetic acid (EDTA) was employed to functionalize single‐mode 28 optical fibers (SMF‐28), and the influence of surface coverage uniformity on zinc ion sensing performance was investigated ...
