Gastrointestinal stromal tumors (GISTs) are the most frequent mesenchymal tumors of the gastrointestinal tract. A definition of a new entity among the gastrointestinal mesenchymal tumors called the gastrointestinal stromal tumors (GISTs) which express the kit (CD117) protein a growth factor trans-membrane receptor with tyrosine kinase activity. Surgery is the mainstay of therapy for non-metastatic GISTs. The c-kit tyrosine kinase inhibitor Imatinib (Glivec), was found to be useful in treating GISTs, leading to a 40-70% response rate in metastatic or inoperable cases.The current Response Evaluation Criteria in solid tumors are based on uni-dimensional tumor size, and do not take into account changes in responding GISTs such as a decrease in tumor density and decrease in the number of intra-tumoral vessels with CT. PET/CT is highly sensitive in assessment early response to Imatinib mesylate. Also, it is useful in predicting long-term response to imatinib in patients with metastatic GIST, however, widespread use of PET is limited because of cost constraints.

Text summarization systems generates summary of articles that makes users to quickly identify the theme of the retrieved articles. Summary can be viewed as gists, table of contents, outlines, minutes, previews, abstracts, synopses, reviews, digests, abridgments, biographies, bulletins, histories and sound bites. gist of an article offers important clues that can help the reader to quickly decide whether to skip, to scan or to read the article. An attempt is made to extract a generic text summary that identifies topic sentences of Hindi text article. Our method aims at to rank the sentences in the article by using different surface features and extract the higher ranked sentences in order to generate a summary with an extensive coverage of the main content of the news article. Various evaluation techniques are used to compare the machine generated output with human generated summaries.

Multiphase reactor analysis for Fischer-Tropsch...

Gas-inducing stirred tank reactors (GISTs) are very attractive for industrial chemical processes where efficient mixing holds the key to superior product yield and quality particularly in situations where the reaction has a low conversion per pass as is the case for the Fischer-Tropsch (FT) synthesis. However, the benefits can only be properly harnessed if there is a reliable set of quantitative relations between operating variables and the mixing attributes as well as reaction metrics. Thus, this book provides a pioneering investigation of electrical process tomography-aided GIST operation based on the FT reaction in order to correlate reaction metrics with mixing characteristics. The technique is non-invasive, using electrical signals corresponding to changes in the component distribution within the vessel with the aid of reconstruction algorithms. In addition, CFD also was used to elucidate the hydrodynamic behaviour within the system. In the FT reaction, the steady-state gas phase hold-up dependency on temperature was shown to be due to contributions from both thermal expansion and reaction-induced changes in the liquid phase.
