Cut-elimination is one of the most important techniques in proof theory. Roughly speaking, eliminating cuts from a proof generates a new proof without lemmas, which essentially consists of the syntactic material of the proven theorem. Traditionally cutelimination served the purpose to show consistency of calculi and thus played a central role in metamathematics. In this traditional context the ...

Newton, in an unauthorized textbook, described a process for solving simultaneous equations that later authors applied specifically to linear equations. This method — that Newton did not want to publish, that Euler did not recommend, that Legendre called “ordinary,” and that Gauss called “common” — is now named after Gauss: “Gaussian” elimination. (One suspects, he would not be amused.) Gauss’s...

it has been estimated that nearly half of the world’s population is at the risk of contracting malaria with sub saharan africa being the most risky area. the existing frontline malaria control interventions are not only expensive but also become ineffective owing to the emergence of insecticide and drug resistance. it calls for an innovative approach in terms of potential and reliable vaccine a...

Propene dissociation channels were characterized by ab initio CCSD(T)/6-311++g(d,p) calculations. Inthis work the detailed mechanism of propene dissociation to C2H4+CH2, C2H2+H+CH3, C2H2+CH4 andC3H3+H2+H have been investigated. According to our calculations, ten fragments can be classified intofive dissociated channels. Our results point out that two mechanisms come into play in the H2 eliminat...

We believe that NGOs, engaged in leprosy control in metropolitan cities where there are many dermatologists in medical colleges, or in private practice, have a special responsibility in implementing leprosy work in an integrated manner. It may be worthwhile narrating the experience of over 3 decades of the Bombay Leprosy Project (BLP) as the Project has been constantly striving to practise all ...

the sources of groundwater pollution such as, industrial effluents, sewage and extensive farming have lead to agrochemical pollution. mathematical modeling helps to analyze the existing situation, allows forecasting, and to evaluate the effects of changes in the surrounding water quality. the present research has been focused mainly towards understanding the various processes affecting the tran...

one of the most paramount processes that play a considerable role in reducing the concentration of heavy metals during estuarine mixing is flocculation. not only does such a process cause a huge percentage of metals to come into the particulate phase, but also it provides ample nutrients for the aquatic life. in the present study, impact of such factors as salinity, ph and do on flocculation of...
