A 78-year-old woman was found dead in her basement. Qualitative screening of available postmortem specimens detected the presence of diltiazem and pentoxifylline. Quantitations were carried out by gas chromatography using nitrogen-phosphorus detection and confirmed by gas chromatography-mass spectrometry with the following results: blood, 0.59 mg/dL diltiazem and 0.63 mg/dL pentoxifylline; urin...

in the present study, an investigation was carried out on parvadeh coal mine in tabas, iran, to survey the effect of fractures on unusual methane gas emission in coal mines. this coal mine was chosen for investigating because of its high methane gas content in the coal body and available data from sensors in desired locations. gas concentration monitoring programs were carried out at the mine s...

in this study, medium density fiberboard (mdf), was produced by dry process using refined fibers from choob khazare caspian amol factory, with 3 levels of urea formaldehyde adhesive at 8, 10, and 12 percent, and 3 levels of paraffin at 0.5, 1, and 1.5 percent. from every treatment, cylindrical samples for permeability measurement with 13 mm in diameter, and 30 mm of height were cut using hole-s...
