This paper describes an image analysis technique for automated estimation of the percentages of epithelium and stroma in (tumor) tissue. The program is evaluated on ovarian tumors of the serous, mucinous, and endometrioid type. From standard paraffin sections, stained with pararosanilin Feulgen and naphthol yellow, a blue-yellow image pair was recorded. The blue image was used for the determina...

External quantum efficiency of industrial-grade green InGaN light-emitting diodes (LEDs) 14 has been measured in a wide range of operating currents at various temperatures from 13 K to 300 15 K. Unlike blue LEDs, the efficiency as a function of current is found to have a multi-peak character, 16 which could not be fitted by a simple ABC-model. This observation correlated with splitting of LED 1...

Atmospheric parameters (Teff , log g and log nHe nH ) are derived for 42 hot horizontal branch (HB) stars in the globular cluster NGC6752. For 19 stars Mg II and Fe II lines are detected indicating an iron enrichment by a factor 50 on average with respect to the cluster abundance whereas the magnesium abundances are consistent with the cluster metallicity. This finding adds to the growing evide...

To evaluate which dye is effective in a plate assay for detecting extracellular cellulase activity produced by fungi, four chromogenic dyes including remazol brilliant blue, phenol red, congo red, and tryphan blue, were compared using chromagenic media. For the comparison, 19 fungal species belonging to three phyla, ascomycota, basidiomycota, and zygomycota were inoculated onto yeast nitrogen-b...

Little information is available on private payer claims cost experience for specific categories of health care. A study was conducted in which physician-claims cost experience and trends among 15 Blue Cross and Blue Shield Plans were compared. Between 1986 and 1988, physician claims cost per covered person increased at an average annual rate of 17 percent, approximately 6 percentage points high...

(FT) Raman spectroscopy is used for the first time to identify pigments used in 19 & 20 century Japanese and Vietnamese Lacquerwares. IR spectroscopy is used to assess the Lacquer matrix. Different operative conditions and parameters were experimented with on a limited number of lacquerwares in order to determine the optimal procedure for the identification of pigments/dyes as potential chronol...

purpose: ‏to determine the visual and anatomic outcomes of epikeratoplasty in 7 eyes of 6 patients with keratoglobus. method: in a retrospective interventional case series, seven eyes of six patients with keratoglaobus (kgb) aged 5 to 39 years underwent epikeratoplasty. three patients (3 eyes) had blue sclera, hypermobile joints, and consanguineous parents and 3 patients (4 eyes) had only kgb. ...

background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...
