detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
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...
Neural Correlates of Contrast Detection at Threshold
Human psychophysical studies have demonstrated that, for stimuli near the threshold of visibility, detection of motion in one direction is unaffected by the superimposition of motion in the opposite direction. To investigate the neural basis for this perceptual phenomenon, we recorded from directionally selective neurons in macaque visual area MT (middle temporal visual area). Contrast threshol...
متن کاملEquivalence of threshold detection with and without dead time.
The correlation function between g, and g 2 is generally represented in the frequency plane by G1(f)G 2 *(f), where G 2 *(f) is the complex conjugate of G 2 ([). In the case of a real function g 2 , G 2 *(f) = G 2 (-f). Thus, considering Eq. (8), the axis x now contains the correlation between g, and g 2 , since the frequency axis for G 2 has been reversed. Values of 0 other than J45 0 provide ...
متن کاملA Comparative Study of Hearing Threshold in Women With and Without Iron Deficiency Anemia
Background: Iron Deficiency Anemia (IDA) is the most common form of anemia. Understanding the relationship between IDA and hearing loss may provide new insights into managing hearing loss. Objective This study aimed to investigate the relationship between IDA and hearing loss in women aged 12-45 years referred to Amir Al-Momenin and Al-Zahra hospitals in Rasht City, Iran. Methods: In this cas...
متن کاملShot boundary detection without threshold parameters
Automatic shot boundary detection is a field, where many techniques and methods have been proposed and have claimed to perform reliably, especially for abrupt scene cut detection. However, all the proposed methods share a common drawback: the necessity of a threshold value, which is used as a reference for detecting scene changes. The determination of the appropriate value or the dynamic reesti...
