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...
• We propose an algorithm that unifies the distance and recall criteria for approximate k-Nearest-Neighbor problem. The is first one studied problem provides theoretical guarantee on both approximation criteria. achieves sub-linear query time while providing guarantees. In this paper we k-Nearest-Neighbors According to existing researches, there are two kinds of One criterion, other criterion. ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
Given the reduced freshwater supplies across the world, seawater desalination is one of the appropriate methods available for producing freshwater. Selecting an optimal location is crucial in the installation of these plants owing to the environmental problems they cause. The present study was conducted to identify optimal locations for installing desalination Plants in the coastal areas of sou...
Abstract Adhesion between an elastic body and a smooth, rigid substrate can lead to large tensile stresses them. However, most macroscopic objects are microscopically rough, which strongly suppresses adhesion. A fierce debate has unfolded recently as whether local or global parameters determine the crossover small Here, we report simulations revealing that dependence of pull-off force F n on su...
Background and aims: HSE performance assessment is one of important requirement for HSE improvement. Apparently, the previous HSE performance assessment models have not considered all of the performance assessment criteria. On the other hand, foreign models can not culturally be applied in describing HSE performance in Iranian organizations. Therefore, this study was conduct...
An indicator variable was developed that may be used to visualize and detect bi–directionality in wind tunnel strain–gage balance calibration data. First, the calculation of the indicator variable is explained in detail. Then, an empirical criterion is proposed that may be used to decide which load components of a balance have bi–directional behavior. The criterion could be used, for example, t...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
ii abstract the legend of human being’s refulgence was distorted completely in the age of modernity. this new age, had some drastic negative effects, besides its positive qualities. one significant negative effect of it was the emergence of neurosis in human beings. aldous huxley’s brave new world was one of the novels of the 02 th century that contained the prophecy of criticizing ...
