Experimental solubility curves and tie-line data for the (water + phenol + 2-ethyl-1-hexanol) system was obtained at T = 298.2 K and atmospheric pressure. The tie-line data was determined by techniques karl-fischer and refractometry. This ternary system exhibits type-2 behavior of LLE. Distribution coefficients and separation factors were measured to evaluate the extracting ability of the solve...

inguinal hernias sometimes surprise surgeons with unexpected contents. this article reports a 46-year-old male with a painless inguinal mass. surgical exploration showed three smooth yellowish concretions in the hernia sac. to our knowledge, this is the first report of hernial sac lithiasis.

This review highlights several important electrocatalytic reactions performed over single-atomic synergistic structures, including SAC-nanoparticles (SAC-NPs), SAC-clusters (SACCs), dual-atom sites (DACs), and alloys (SAAs).

in spite of being histologically benign, sacrococcygeal teratoma (sct) may recur either as a benign or malignant tumor. a total of 26 patients with benign neonatal scts were treated in taleghanee and mofid medical centers from 1986 to 2000. investigations included radiography,abdominal ultrasound and computed tomography (ct) scan and measurement of tumor marker (α-fetoprotein). initial surgical...

A continuous flow apparatus was applied to measure the phase equilibrium at 523 K and 573 K. The performance of analysed with determination vapor pressures water temperatures ( T = 453 473 K). measured deviated from literature values less than 1 %. Vapor n -dodecane, -hexadecane phenol were 523–623 K) and, bubble point -dodecane + pure components compared values. Relative pressure value 2 % for...

in a prospective survey, 200 cases of operated chronic dacryocystitis were divided into three groups according to the kind of operation, and the respective results are as follows: group i includes 100 cases in whom the lacrimal bone was removed (8mm x 8mm) and a 6mm diameter catheter was used (as a duct between the lacrimal sac and nasal cavity). the recurrence rate within one year was 24 % . g...
