This study reports the practical problems involved in the use of a miniature Geiger counter to detect the site of bleeding into the intestine. The observations so far have been made in dogs but its possible application in man is proposed.

In this research, the polar decomposition (PD) method is applied to experimental Mueller matrices (MMs) measured on two-dimensional microstructured surfaces. Polarization information is expressed through a set of parameters of easier physical interpretation. It is shown that evaluating the first derivative of the retardation parameter, δ, a clear indication of the presence of defects either bui...

T H E R E are on the market automatic counters which can rapidly assess the percentage of cells in a population which have a single simple characteristic. An excellent example is the Coulter counter which can assess the size distribution of the cells in a suspension by means of the change in electrical properties that they cause in the surrounding fluid. Another is the scanning microscope which...

Octahedral and cubic NiS2 nanocrystals enclosed by {111} and {100} planes were separately used as counter electrodes (CEs) incorporated into Pt-free dye-sensitized solar cells (DSSCs). The DSSC assembled by NiS2 octahedrons exhibited a conversion efficiency of 5.98%, better than that by NiS2 cubes (5.43%). DFT calculations indicate that the better catalytic effect could be ascribed to higher su...

The killing and postantibiotic effects (PAE) of cefotaxime, ciprofloxacin, and gentamicin against Escherichia coli were determined in Mueller-Hinton broth (MHB) and pooled human cerebrospinal fluid (CSF). MICs performed in MHB and CSF were within one dilution for all antimicrobial agent-organism combinations. At two times the MIC, CSF significantly (P less than 0.05) increased the duration of t...
