THE DEVELOPMENT AND VALIDATION OF VISIBLE SPECTROPHOTOMETRIC METHODS FOR SIMVASTATIN DETERMINATION IN PURE AND THE TABLET DOSAGE FORMS [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2008
Two simple and sensitive spectrophotometric methods have been developed for the determination of simvastatin (SMT) in pure form and in tablets using insitu generated bromine, and p-phenylenediamine (PPDA) or o-dianisidine (ODA) as reagents.

Determinants of Collateral [PDF]

open access: yesSSRN Electronic Journal, 2004
This paper draws upon the theory of contracting under asymmetric information to postulate and test several hypotheses concerning the relationship between the use and amount of collateral in financial loans to firms, the risk profile of the borrower, business cycle and monetary conditions of the economy, strength of the lending relation between borrower

Reality, Determination, Imagination

open access: yesOpen Philosophy, 2020
In contemporary debates, the realist position (here speculative realism/materialism is of particular interest) not only implies a belief in what is real, but also allows us to ascertain a certain possibility of accessing reality, thus bringing about the ...

Stabilizer group of generalized determinant [PDF]

open access: yesarXiv, 2017
In this paper, we consider linear combination of determinant and permanent, which we call generalized determinant, and determine the stabilizer group of it.

Determining Determiner Sequencing: A Syntactic Analysis for English [PDF]

open access: yesarXiv, 1994
Previous work on English determiners has primarily concentrated on their semantics or scoping properties rather than their complex ordering behavior. The little work that has been done on determiner ordering generally splits determiners into three subcategories.

Enumeration of Point-Determining Graphs [PDF]

open access: yesarXiv, 2007
Point-determining graphs are graphs in which no two vertices have the same neighborhoods, co-point-determining graphs are those whose complements are point-determining, and bi-point-determining graphs are those both point-determining and co-point-determining.

Moment determinants as isomonodromic tau functions [PDF]

open access: yes, 2008
We consider a wide class of determinants whose entries are moments of the so-called semiclassical functionals and we show that they are tau functions for an appropriate isomonodromic family which depends on the parameters of the symbols for the functionals.
