Pyrolysis Characteristic of Tobacco Stem Studied by Py-GC/MS, TG-FTIR, and TG-MS

Pyrolysis Characteristic of Tobacco Stem Studied by Py- GC/MS, TG-FTIR, and TG-MS

Pyrolysis characteristics and mechanism of tobacco stem were studied by pyrolysis coupled with gas chromatography/mass spectrometry (PyGC/MS), thermogravimetric analyzer coupled with Fourier transform infrared spectrometry, and mass spectrometry (TG-FTIR and TG-MS) techniques. The composition of evolved volatiles from fast pyrolysis of tobacco stem was determined by Py-GC/MS analysis, and the e...

TG-21 versus TG-25: a comparison for electrons.

Since 1984, the Radiological Physics Center (RPC) has used the American Association of Physicists in Medicine Task Group 21 (TG-21) protocol (absorbed dose determination) as the basis of its On-site Dosimetry Review visits to institutions participating in the National Cancer Institute's cooperative clinical trials. Subsequent to the TG-21 protocol, the Task Group 25 (TG-25) report on electron-b...

Analyzing uncertainty in TG protection graphs with TG/MC

We introduce TG/MC, a Monte-Carlo approach for evaluating the impact of uncertainty about vulnerabilities upon forecasts of security for a real-world system modeled by a protection graph. A TG/MC model defines a vulnerability as a potential change to an otherwise safe initial protection graph that, if exploited, leads to an unauthorized state, a violation of the system’s security policy through...

Polymer Analysis Using Pyrolysis-GC-FTIR-MS and GC-AED

Shallow Analysis Generation TG

Appointment scheduling is a problem faced daily by many individuals and organizations. Cooperating agent systems have been developed to partially automate this task. In order to extend the circle of participants as far as possible we advocate the use of natural language transmitted by email. We describe Cosma, a fully implemented German language server for existing appointment scheduling agent ...
