in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
in chapter 1, charactrizations of fragmentability, which are obtained by namioka (37), ribarska (45) and kenderov-moors (32), are given. also the connection between fragmentability and its variants and other topics in banach spaces such as analytic space, the radone-nikodym property, differentiability of convex functions, kadec renorming are discussed. in chapter 2, we use game characterization...
this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...
In the last lecture we discussed applications of log concavity of real rooted polynomials in designing a deterministic approximation algorithm for permanent. We also introduced the class H-stable polynomial. Recall that a polynomial p(z1, . . . , zn) is H -stable if p(z1, . . . , zn) 6= 0 whenever =zi > 0 for all i. In the last lecture we saw that any univariate H-stable polynomial (with real c...
For n<105 all coefficients of Fn(x) are ±1 or 0. For n = 10S, the coefficient 2 occurs for the first time. Denote by A w the greatest coefficient of Fn(x) (in absolute value). Schur proved that lim sup -4n= °°. Emma Lehmer proved that An>cn l,z for infinitely many n. In fact she proved that infinitely many such w's are of the form pqr with p, q, and r prime. In the present note we are going to ...
the current thesis is composed in five chapters in the following fashion: chapter two encompasses the applied framework of the project in details; the methodology of carl gustav jung to explain the process of individuation, the major archetypes and their attributes and his techniques to assess the mind’s strata are all explained. moreover, the austrian psychoanalysts, heinz kohut’s models of a...
The complexity of calculating the coefficients of the Tutte polynomial of a graph is considered. The calculation of some coefficients is shown to be # P-complete, whereas some other coefficients can be computed in polynomial time. However, even for a hard coefficient, it can be decided in polynomial time whether it is less than a fixed constant.
