We perform a linguistic analysis of documents during indexing for information retrieval. By eliminating index terms that occur only in subordinate clauses, index size is reduced by approximately 30% without adversely affecting precision or recall. These results hold for two corpora: a sample of the world wide web and an electronic encyclopedia.
We present an efﬁcient algorithm for the redundancy elimination problem: Given an underspeciﬁed semantic representation (USR) of a scope ambiguity, compute an USR with fewer mutually equivalent readings. The algorithm operates on underspeciﬁed chart representations which are derived from dominance graphs; it can be applied to the USRs computed by large-scale grammars. We evaluate the algorithm on a corpus, and show that it reduces the degree of ambiguity signiﬁcantly while taking negligible runtime. ...
Compared with hydrophilic drugs not undergoing transport, lipophilic drugs are more rapidly taken up from the blood into hepatocytes and more readily gain access to mixed-function oxidases embedded in sER membranes. For instance, a drug having lipophilicity by virtue of an aromatic substituent (phenyl ring) (B) can be hydroxylated and, thus, become more hydrophilic (Phase I reaction, p. 34). Besides oxidases, sER also contains reductases and glucuronyl transferases. The latter conjugate glucuronic acid with hydroxyl, carboxyl, amine, and amide groups (p.
Explain the role of biotransformation in toxicokinetics. • Describe how biotransformation facilitates elimination of toxicants. • Distinguish between Phase I and Phase II reactions. • Define bioactivation or toxication.
Self-controlling over work can help people to actively carry out their work, flexibly solve problem and feel owning the result
It highly and intrinsically motivates employees.
But old style managers have tried to control what, when and how their people perform work.
It causes contaminant in work place.
Pressures for local responsiveness
The solid product is a wet sludge of calcium sulfate which can be disposed of easily. So
FGD does not eliminate pollution. What it does accomplish is to convert a big problem
(emission of large volumes of air contaminated by harmful levels of gaseous SOx) into a
small problem (collection and disposal of scrubber sludge).
Dealing with the problem of air pollution is not cheap. An FGD system installed in a
newly constructed power plant represents about one-third of the total cost of building the
