all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
let g=(v,e) be a graph with vertex set v and edge set e.for two vertices u,v of g ,the closed interval i[u,v] ,consists of u,v and all vertices lying in some u-v geodesic in g.if s is a set of vertices of g then i[s]is the union of all sets i[u,v]for u,v ? s. if i[s]=v(g) , then s is a geodetic set for g.the geodetic number g(g) is the minimum cardinality of geodetic set.the maximum cardinalit...
abstract venlafaxine, 1–[2–(dimethylamino)–1–(4–methoxyphenyl) ethyl]cyclohexanol hydrochloride is a novel non-tricyclic antidepressant. venlafaxine is a second generation antidepressant drug, has a neuropharmacologic profile distinct from that of existing antidepressants including tricyclic compounds, selective serotonin reuptake inhibitors and monoamine oxidase inhibitors. venlafaxine impart...
Theoretical Study of the Spatial Resolution of X-ray Microanalysis in Analytical Electron Microscopy
The spatial resolution of X-ray microanalysis has been investigated by Monte Carlo calculatio~s, including knock-on secondary electron production. The results for AuMa in a lOOOA thin Au film at 100 keV showed an appreciable difference from the ones without knock-out events. Also calculations have been done with the Mott cross-section instead of the screened Rutherford cross-section for elastic...
where the functions Ga(x1, x2), Eb(x ′ 1, x ′ 2) and Êc(z1, z2) are the twist-3 quantities representing, respectively, the transversely polarized distribution, the unpolarized distribution, and the fragmentation function for the pion. δqa(x) is the transversity distribution in p↑. a, b and c stand for the parton’s species, sum over which is implied. δqa, Eb and Êc are chiral-odd. Corresponding ...
An interactive modeling system for implicit curves is presented. Unlike other interactive algorithms, ours displays connected polygonal approximations instead of several unconnected points. We also guarantee that the topology of our polygonal approximation matches the topology of the true curve. The system currently handles only 2-D blobby curves, but will be extended to include general 3-D imp...

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 this paper, an ultra low carbon high strength low alloy grade steel was subjected to a two-step forging processand this was followed by different post cooling methods. the highest strength was obtained at a faster coolingrate due to the highly dislocated acicular ferrite structure with the fine precipitation of microalloying carbides andcarbonitrides. at a slow cooling rate, the strength fel...
