The rates of oxidation of four chelating agents with Ce(IV) in HC104 solutions, have been studied by the stopped-flow technique. The rates first increase with increasing acidity, reach maxima which are characteristic of the chelating agent and the medium, then progressively decrease with further increasing acid concentration. At their maximum reactivities, the tendencies for oxidation decrease ...

x-acetylaminofiuorene N-hydroxy-2-acetylamino fluorene x-hydroxy-2-acetylamino fluorene 2-hydroxylaminonaphthalene Recently it has become apparent that an increasing number of carcinogens are capable of interacting with nucleic acids (10, 14, 923). These observations may be causally related to the mech anism of carcinogenesis as being a special case of mutagenesis. The chemical reactions of som...

An inference based method for modeling complex non linear systems is presented that integrates current approaches to mod eling of microwave devices within a gen eralized non linear framework Familiar techniques for characterizing and emulat ing linear and non linear systems are em bedded in an automated weighting mech anism so that globally complex behavior is approximated by a number of simple...

The continuous mobilization of vehicles has led to a surge in the number road accidents across world. To get better at this, government is trying focus on safest and most preventive measures traffic. practice direct observation found be time taking lot human effort needed. So, our main idea introduce helmet license plate detection mech- anism. This project attempts implement process through few...

The collapse of the Fundão dam is one greatest socio-environmental calamities. In order tospeed up repair and compensation process, Fundação Renova was created, an entity resposible for Me-diated Indemnity Program (MIP), designed to deter-mining amounts be paid. Faced with ex-posed situation, this paper analyzes obstacles negotiator's dilemma access justice, through mediation, based on adversit...

We describe SCC kS a Speculative Concurrency Control SCC algorithm that allows a DBMS to use e ciently the extra computing resources avail able in the system to increase the likelihood of timely commitment of transactions Using SCC kS up to k shadow transactions execute speculatively on behalf of a given uncommitted transaction so as to protect against the hazards of blockages and restarts SCC ...

HST observations have contributed significantly to our knowledge on the behaviour of Isolated Neutron Stars (INSs) as optical emitters. First, HST has been instrumental both to discover new optical counterparts (PSR B1055-52, PSR B1929+10, PSR B0950+08) and to confirm proposed identifications (PSR B0656+14). Second, HST multicolor photometry provided useful information to characterize the optic...

The paper describes some experintental investigations of the formation and collapse of cavitation bubbles. The experiments were carried on in the high-speed water tunnel of the Hydrodynantics Laboratory of the California Institute of Technology under the sponsorship of the Research and Development Division of the Bureau of Ordnan ce of the U. S. Navy and the Fluid Mechanics Section of the Offic...

When agents have quasi-linear preferences, every incentive compati-ble social choice function can be implemented by a simple extensive form mech-anism, even if agents are allowed to use mixed strategies. The second stage of themechanism, which is used to elicit the agents' true preferences, is not reached inequilibrium; it gives agents strict dominant strategies, so equilibrium ...

Possibilistic logic is an important uncertainty reasoning mech anism based on Zadeh s possibility theory and classical logic The deduc tion rules of possibilistic logic have been obtained from classical resolu tion rule by attaching possibility or necessity weight to ordinary clauses However since not all possibility valued formulae can be converted into equivalent possibilistic clauses the res...
