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...
Woody vegetation landscape features, such as hedges, tree patches, and riparian vegetation, are important elements of biotic diversity. For the reason that biodiversity loss is one major ecological problems in EU, it necessary to establish efficient workflows for registration monitoring woody features. In paper, we propose evaluate a methodology automated detection changes features from digital...
Dissolved organic nitrogen (DON) and phosphorus (DOP) represent themost abundant formof their respective nutrient pool in the surface layer of the oligotrophic oceans and play an important role in nutrient cycling and productivity. Since DOP is generally more labile than DON, it provides additional P that may stimulate growth of nitrogen-fixing diazotrophs that supply fixed nitrogen to balance ...
The degree of polarization (DOP) of luminescence of III-V materials is a sensitive function of the strain in the material. The DOP can be measured with a spatial resolution of roughly 1 μm and an rms noise equivalent to a strain difference of 2H10. The DOP can be measured on cleaved facets, surfaces free of metals, or luminescent layers buried by transparent materials or thin films. Thus maps o...
Amphetamine (AMPH) poses a serious hazard to public health. Defining the molecular targets of AMPH is essential to developing treatments for psychostimulant abuse. AMPH elicits its behavioral effects primarily by increasing extracellular dopamine (DA) levels through the reversal of the DA transporter (DAT) cycle and, as a consequence, altering DA signaling. In Caenorhabditis elegans, an excess ...
A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...
In this paper we employ a most recent approach to Data Oriented Parsing (DOP), which has named Double-Dop, for Persian sentences. Like other DOP models, Double-Dop parser utilizes syntactic fragments of arbitrary size from a treebank to analyse new sentences, but it extracts a restricted yet representative subset of fragments. It uses only those which are encountered at least twice. The accurac...
Data-Oriented Parsing (DOP) models of natural language propose that human language processing works with representations of concrete past language experiences rather than with abstract linguistic rules. These models operate by decomposing the given representations into fragments and recomposing those pieces to analyze new utterances. A probability model is used to select from all possible analy...
