Comments on "arsenic release provided by MTA and Portland cement" by Duarte MA, et al.

The authors presented their data from atomic absorption tests, stating that the cements released less than 0.0007 ppm of arsenic after a week of soaking in weakly acidic solution. That is, the cements released 0.7 ppb from their worst sample. My first comment is on the atomic absorption technique for arsenic. According to the EPA method 7062 for detection of arsenic by atomic absorption using s...

A sensitive and selective liquid chromatography tandem mass spectrometry (LC–MS/MS) method for determination of meropenem in rabbit plasma was developed. After addition of triazolam as internal standard (IS), protein precipitation by acetonitrile was used in sample preparation. Chromatographic separation was achieved on a Restek Allure (TM) PFP Propyl (2.1 mm × 100 mm, 5 μm) column with acetoni...

A sensitive and simple liquid chromatography/electrospray mass spectrometry (LC-MS/MS) method for determination of gefitinib in rat plasma using one-step protein precipitation was developed. After addition of estazolam as internal standard (IS), protein precipitation by acetonitrile was used as sample preparation. Chromatographic separation was achieved on an SB-C18 (2.1 mm × 50 mm, 3.5 μm) col...

NING MA et al: FUSION OF WORD CLUSTERING FEATURES FOR TIBETAN PART OF SPEECH TAGGING

Tibetan Part of Speech (POS) tagging, the foundation of Tibetan natural language processing, judges word classification according to contextual information of words. Based on the framework of the maximum entropy model, the paper studied the fusion of morphological features for Tibetan part of speech with maximum entropy model with the integration of word clustering features. Experimental result...
